Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a moving cart for a rotating machine, which can securely fix the rotating machine to the floor after transporting the rotating machine to a predetermined location, and quickly and accurately move the five-turn machine to other interlocking equipment. The present invention relates to a movable trolley that can be connected to each other and that can mount a variety of rotating machines.

In particular, one aspect of the present invention is an engine dynamometer device for testing the dynamic performance of automobiles, in which a prime mover (particularly an engine) directly connected to a drive shaft is transported to a predetermined installation location, fixed there, and axially aligned.
It is also an extremely convenient mobile trolley for mounting many types of prime movers.

The engine that rotates the dry shaft of this type of engine dynamometer has conventionally been transported on a trolley without any equipment, but due to uneven cross-sections and sloped surfaces, there is a risk of the engine shaking during transportation and falling off the trolley. With,
The engine had to be lowered to its installation location, mounted on a separate frame, aligned, and directly connected to the engine and drive shaft, which required a great deal of time and effort.

Another method is to transport the engine to the installation location using a hoist.

This also has to be fixed to another mount in the same way as above,
Either method has the problem of requiring a lot of time to set up the engine prior to the engine performance test.

The present invention has been proposed in view of the above-mentioned conventional drawbacks.

According to the present invention, the movable trolley has a plywood board that can be moved up and down by a lift jack, and the engine is mounted and fixed thereon so that the height and installation angle can be adjusted freely. The plywood can be lowered and fixed to the floor with fixing bolts,
Direct connection between the engine and drive shaft can be easily achieved.

The base plate is also equipped with a mounting device.

Many types of engines with different shapes and dimensions can be easily installed.

Additionally, if the engine is being transported on a sloping or uneven road surface that is dangerous, the plywood can be lowered onto the floor using a hydraulic release lever at any time.

Hereinafter, embodiments of the present invention will be described in order with reference to the drawings.

In Fig. 1, 1 is an engine mounted on a mobile cart 2, 3 is a drive shaft, 4 is a flywheel, and 5 is a drive shaft.
is a dynamometer.

In the above, the engine 1 and the drive shaft 3 are directly connected with each other with centering, and the structure of the movable trolley 2 is shown in FIGS. 2 and below.

To explain this next, 2a is a truck frame, and wheels 6. γ is the attachment.

8 is a lifting platform. Parallel links 13 and 1 are connected to the front and rear of the bogie frame 2a via pivots 9 and 10 and 11 and 12, respectively.
The engine 1 is mounted on this elevating platform 8.

15 is a lift jack that raises and lowers the elevator platform 8.

16 is its operating lever.

The tip of the operating lever 16 is pivotally supported by a support shaft 1γ on the arm 2a' of the truck frame 2a, and by pushing one gripping rod 16a up and down, the rod 15a of the lift jack 15 can be raised, and conversely, the lowering operation handle 18 By this, the hydraulic pressure can be released and the rod 15a can be lowered.

The lowering operation handle 18 is attached to the upper end of a steering handle 19 rising from the arm 2a' of the truck frame, and its operation shaft 18a rotates to release hydraulic pressure.

The rod 15a is lowered, the details of which will be described later.

The rod 15a of the lift jack 15 and the arm plate 8a of the lifting platform 8 are connected by a link 20.
By raising 5a, the lifting platform 8 can be pulled up diagonally upward via the link 20.

Therefore, at this time, the lifting platform 8 uses one of the support shafts 9, 11 of each link 13.14 as a fixed support, and the other support shaft 10.
By the rotation of the link with 12 as a movable fulcrum, it is lifted diagonally upward, and rises relative to the two-bogie frame 2a, allowing it to float above the floor.

Conversely, when the rod 15a descends, the elevator platform 8 descends.

In Figures 2, 3, and 5, the lifting platform 8 is lowered.

The leg 8b is shown on the floor, and FIG. 6 shows the leg 8b off the floor.

In each figure. The floor surface 21 is provided with a plurality of engagement grooves 21a, 21a, .
The head of a fixing bolt 22 is engaged with 1a so as to be slidable along the groove but not pulled out, and its threaded portion projects upward from the floor surface.

On the other hand, a base plate 8b integrally provided at the lower end of the leg 8b
' is a U whose end into which the fixing bolt 22 fits is open.
A long hole 23 is provided so that the nuts 1-24 can be tightened and fixed from the upper side of the base plate 8b'.

Therefore, as shown in FIG. 6, the lift jack 15 lifts the platform 8 by a height h from the floor surface 21, and the wheels 6. γ moves the mobile cart 2 to a predetermined installation location, and lifts the platform 8.
When it is lowered and landed on the floor and the nuts 24 are tightened on the fixing bolts 22 protruding from the U-shaped elongated holes 23, the floor surface 21, the movable cart 2, and the elevator platform 8 are securely fixed.

Since the U-shaped elongated hole 23 is an elongated hole with an open end, it is possible to search for the fixing bolt 22 from the material side after the movable cart is placed on the floor.

Reference numeral 25 is an idle roller whose mounting shaft 25a is fixed to the engagement groove 21a in the center, and a guide plate 26 disposed parallel to the back side of the lifting platform 8 engages with this guide roller.

Since the tip 26a of the guide plate 26 expands outward, when the moving cart 2 moves, one end 26a of the guide plate is guided by the guide roller 25 even if the direction is slightly deviated. This automatically corrects any misalignment and allows the device to be placed at a predetermined location.

Reference numeral 2γ denotes an oil reservoir provided under the lifting platform 8, and an oil drain pipe 28 led out from the lower part is led to the side of the leg 8b.

A drain cock 29 is provided at its tip, so that oil leaked from the engine 1 can be received in the core oil reservoir 2γ and drained by opening the drain cock 29.

Next, to explain the lift jack 15 and its related operating mechanism, in FIGS. 5, 7, 8, etc., 30 is a hydraulic pressure raising rod attached to the rod 15a with the link 20 pivotally supported at the upper end. The lower hydraulic chamber 31 is a pressure circuit 32
The pressure circuit 32 is connected to the hydraulic chamber 35 of the rod 15a through a ball valve 33, and the no-load circuit 36 is connected to the cylinder of the rod 15a through a ball valve 38.39. Oil chamber 3 formed on the outer periphery of 15b
It communicates with γ.

The upper end of the hydraulic pressure raising rod 30 and the base end of the operating lever 16 of the lift jack are connected by a spring 41 via a shaft 40 and a hydraulic pressure raising lever 42.

therefore. By operating the operating lever 16 up and down, pressure oil is supplied from the pressure circuit 32 to the hydraulic chamber 35, the rod 15a is raised, and the elevator platform 8 is lifted up via the link 20.

The pressure circuit 32 also leads to the receptacle of the respective ball valve 4γ, 48 of the valve actuation rod 43,44.

Furthermore, the return circuits 45, 46 are connected to the ball valves 41, 48
The housing part communicates with the upper and lower parts of the oil chamber 37.

The tip of one of the valve operating rods 43 is threaded, and its upper end is connected to the lower end of the lowering operation handle 18 of the lift jack via a shaft joint 18b.

The other valve operating rod 44 is of a sliding type, and its end is in contact with the tip of a rotating lever 50 that is pivotally supported on a pivot 49.

The lower end of a cable wire 51a housed in a tube 51 is connected to the other end of the rotating lever 50, and the upper end of the cable wire 51a is led to the upper part of the steering handle 19, and an emergency release lever 52 is attached. There is.

Therefore, when moving the mobile cart 2 to the engine installation location and slowly lowering the elevator platform 8, turn the lowering operation handle 18, screw the valve operating rod 43 along the threaded portion, and slowly move it upward. By opening the ball valve 47, the pressure oil in the pressure circuit 32 communicating with the hydraulic chamber 35 can be gradually returned to the oil chamber 3γ through the return circuit 46,
Therefore, the lifting platform 8 can be lowered by lowering the rod 15a.

On the other hand, if an emergency situation occurs, such as when the cart 2 on which the engine 1 is mounted is tilted on an uneven road surface or a slope, and there is a risk that the engine will fall, the valve operating rod 44 is released by operating the emergency release lever 52. The ball valve 48 is rapidly opened by sliding the rod 15 , and the pressure oil in the pressure circuit 32 is returned to the oil chamber 31 through the return circuit 45 .
It is possible to make a steep drop.

At this time, since the lifting platform 8 descends and lands on the ground, the engine mounted thereon comes to a standstill, eliminating the risk of falling.

Next, details of the mounting device 53 for mounting the engine 1 on the lifting platform 8 will be explained with reference to FIGS. 9 to 12.

The mount device 53 is used to mount engines of different models and models, adjust the height of the engine, and ensure reliable connection with the drive shaft 3, and can be raised and lowered as shown in the plan view in FIG. They are placed on both sides of platform 8.

Both ends of the engine 1 are supported.

In each figure, 55c is a mounting base fixed to the lifting table 8, and 55 is a support stand integrated with the mounting base.

A ring nut 56 having a handle 56a on the outer periphery is rotatably supported on the support base 55, and
It can be fixed with a fixing bolt 55a provided on the support stand 55.

5γ is a support using a square threaded rod screwed into a ring nut 56, and a base 58 is attached to the upper end of the support.

The keyway 57a fits into the key 55b of the support base 55.

59 is a bottom plate 59a fixed to the movable base 60 with bolts 61
and side plates 59b, 59b standing up from both ends of the bottom plate.
The engine mounting consists of a fixing bracket for the engine.

Further, 62 is a flat plate 62a and side plates 62 attached to both ends thereof.
This is a movable bracket for mounting an engine, consisting of 62b and 62b.

A boss 59c is provided at the rear end of the upper end of the side plate of the fixed bracket 59 and at the rear end of the flat plate 62a of the movable bracket 62.

59c and 62c are fixed, and the pivot 65 passes through them.

Further, the side plates 62b, 62b of the movable bracket 62 have a plurality of bolt holes 63,
63... and the side plate 59b of the fixed bracket 59.

59b is also provided with a plurality of screw holes 64.

Therefore, the flat plate 62a of the movable bracket 62 that supports the engine 1 in the state shown in FIG. can be inserted into the screw hole 64 and locked in the inclined position.

67 is a scale indicating the angle of the flat plate 62a, 68 is a bolt insertion hole for fixing the engine provided in the flat plate, and as shown in Fig. 12, the engine bracket N
d is fixed via an elastic body 80.

Movable base 60 to which the bottom plate 59a of the fixed bracket 59 is attached
An engagement groove 60a is provided on the back surface of the holder.

It is slidably fitted into an engaging protrusion 58a provided on the base 58 via a key 69.

A nozzle 7 is provided at the end of the central recess 70 of the engagement protrusion 58a.
A rotary threaded rod γ1a having a diameter of 1 is inserted, and a movable piece γ2 screwed thereto is connected to the movable base 60.

Therefore, by operating the handle γ1, the movable base 60 is moved to the ninth position.
It can be moved in the direction of the arrow in the figure, and after being moved to a predetermined position, it can be fixed with the fixing pole l-60b.

Therefore, according to the mounting device 53 described above.

Before moving the movable trolley 2 to the installation location, the engine can be set in the preparation room in the following order, and the movable trolley 2 only needs to be fixed at the installation location.

That is, first of all, turn the ring nut 56 and tighten the support 5.
The height of the engine is adjusted by raising and lowering γ, and the movable bracket 62 is roughly rotated around the pivot 65, so that the width of the inclined bottom and the angle of inclination are different depending on the model and size of the engine 1. Decide the inclination angle according to
In one operation, the movable bracket 62 can be moved to the bottom of the engine and brought into contact with the sloping bottom of the bottom of the engine.

The reason why the mounting device 53 is configured to be movable in this manner is due to the size of the engine 1 as described above.

Depending on the model, the width of the lower part and the bottom slope 1a
This is because the angles of inclination (as shown in the third figure) are different, and the support is made accordingly.

Reference numerals 73 and γ3 designate engine support members disposed at intermediate positions on both sides of a pair of opposing mounting devices 53 and 53, which are composed of Pandagraph jacks γ3a, and the support fittings 73b at the upper end are attached to the front and rear sides of the back surface of the lower part of the engine. 1b (second illustration).

and. The front side (steering handle side) pandagraph jack 73a is fixed on the lifting table, and the rear side (counter-steering handle side) can be moved along a guide γ4 provided on the lifting table.

The Pandagraph Jacket γ3a is used when transporting the engine and is subjected to longitudinal shaking, but it is lowered during testing.

In addition, γ5 protects the engine fan 1c, and
A net-like fan cover is attached to the lifting platform 8 via a support member γ6 to prevent the risk of touching the fan cover during operation.

Further, the gripping rod 16a of the operating lever 16 can be rotated upward about the pivot 71 and folded.

Furthermore, when a particularly large engine is mounted, 78 is provided to support it, and is a support member using a panda graph jack.

As explained above, according to two aspects of the present invention, a rotating machine such as an engine is transported by a moving carriage exclusively for the rotating machine, and in particular, the rotating machine is installed on the lifting platform of the moving carriage and is movable in both directions. In addition, since it is supported by a mounting device that can be adjusted to any inclination angle, it is not only possible to simply transport the single-rotation machine, but also to fix it to a fixed plate or attach it to another equipment after moving it to the specified installation location. Centering with rotating machine 2
Direct connection becomes reliable and easy, and the time required for setting can be greatly shortened.

Furthermore, the lifting platform has a simple structure and can be raised and lowered arbitrarily via a lift jack, so that during transportation,
When an emergency situation arises, such as a possibility that the rotating machine may fall, the lifting platform can be quickly placed on the floor, making transportation safe and reliable.
