Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention provides a lid remover for removing a lid placed on a gutter from the gutter for purposes such as cleaning the gutter, drainage work, or replacing the lid. Regarding machines.

(Prior Art) It takes a lot of effort to remove a cover placed on a side gutter as shown in FIG. The reasons for this are that the lid is a so-called drop lid that fits into the lid mounting step of the gutter and is a continuous joint lid, that the lid itself is heavy and thick, and that dirt and dust accumulate in the gap between it and the gutter. This may cause clogging.

Traditionally, the main methods have been to pry it open with a crowbar or pull it up with a clamp, but both require skill and effort, and are likely to damage the lid or injure the worker, and are difficult to do alone. Can not. Attempts have been made to use hydraulic machinery, but the equipment is large and difficult to handle.
It cannot be said that it is a popular type.

In addition, by pushing down on the handle, the bottom side is lifted from the wheel (more precisely, it moves in a circular motion),
There are some gutter cover removal machines that remove the gutter cover between the front and rear claws attached to the bottom side.
In this type of groove lid removal machine, when there is no gap between the joint surfaces of the lids (which is almost the case in recent construction), the groove lids are in a continuous state where the lids are stuck together due to the above circular movement. The first sheet cannot be removed and the last sheet cannot be closed, so it has not become very popular.

(Problems to be Solved by the Invention) The present invention has been made in view of the above-mentioned conventional circumstances, and is capable of quickly, easily, safely and reliably removing the lid with the simple operation of one worker's hands and feet. It is also possible to return the lid (i.e., put the lid on) by reverse action.Furthermore, even when there is no gap between the joint surfaces of the lids, it is possible to use a compound movement that combines vertical movement and rotational movement. The present invention aims to provide a gutter lid removal machine that can smoothly remove and return the lid.

[Structure of the Invention] (Embodiment) To explain the following with reference to the embodiment shown in the drawings, reference numeral 1 denotes a vehicle chassis having front wheels 2 and rear wheels 3, and a holder portion 1a facing diagonally upward is provided at the front portion of the chassis. A tip end 5a of an operating rod 5 is pivotally attached to the holder portion 1a via a pivot 4, and a spring 10 wound around the pivot 4 is locked to the holder portion 1a.

The operating rod 5 is integrally fixed with a rear claw piece 6 having a hook portion 6a formed at its tip in the direction of extension of the most distal end, and is attached to a holder portion 5b formed upwardly of the tip portion 5a at a predetermined angle with the operating rod 5. The proximal end of a sliding shaft 7 that holds and can rotate outside the corner is pivotally connected via a pivot pin 8.

This sliding shaft 7 has an adjustment hole 11a and an adjustment bolt 1.
It consists of a base tube shaft 11 having a diameter of 1b and an insertion shaft 12, and a front claw piece 9 is provided in a direction perpendicular to the tip of the insertion shaft 12.
is fixed.

In the drawing, 13 is a handle of the operating rod 5, and 14 is a support rod fixed downwardly in the middle of the operating rod 5.

(Function) The lid removing operation performed by the machine of the present invention having the above-described configuration will be explained step by step as shown in FIG.

(a) First, position the machine in the longitudinal direction of the gutter and move it forward to the target gutter cover G while pushing up the handle 13 (therefore, the operating rod 5).

(b) Then, insert the front claw piece 9 at the tip of the sliding shaft 7 and the rear claw piece 6 at the tip of the operating rod 5 into the abutment notch H of the gutter cover G, and then move it forward slightly to tighten the tip hook of the rear claw piece 6. Hook the part 6a onto the lower edge of the lid H.
That is, as a result, the lid H is held between the front claw piece 9 and the rear claw piece 6 (at this time, the vehicle platform 1 rises by a predetermined angle above the ground with the pivot 4 as the base point).

Even if you try to pull down the operating rod 5 in this state, since the movement of the sliding shaft 7 accompanying the pulling down movement is a circular motion, the lids G, which are installed continuously without any gaps, will collide with each other, making it impossible to remove the lid G. be.

(c) Then, from this state, press the rear end of the chassis 1 slightly as if it were a pedal. Then, the front wheels 2 move forward slightly, and the holder part 1a at the front of the chassis 1 resists the spring 10 to levitate the aircraft due to the action of the lever, so a vertical force is applied to the lid G held between the front and rear claws 9 and 6. works, and the thick lid G slips out from the lid mounting step of the side gutter.

(iv) From this state, the operating lever 5 is further lowered by the action of the lever, and the sliding shaft 7 is given circular motion about the pivot shaft 4 to completely remove the lid G.

In other words, collision between the lids H is avoided by adding vertical motion immediately before starting the circular motion and shifting the pivot point position of the circular motion upward. Therefore, the above (c) and this (d) are performed almost simultaneously in time as a compound movement.

(e) Then, with the operating rod 5 lowered to the bottom dead center (the position where the support rod 14 hits the chassis 1 part), pull the handle 13 toward you to carry it to an appropriate location, (f) Finally, move the chassis 1 While depressing the button, push up the operating rod 5 again to remove the lid H from the front and rear claws 9 and 6.

It will be easily understood that the lid can be restored (covered) by reversing the above sequence of operations.

[Effects of the Invention] As described above, the present invention allows the lid H to be opened extremely quickly, easily, and safely and reliably by the simple operation of the double levers of the operating rod 5 and the chassis 1 by one worker's limb movements. The lid can be removed or put on, and by adding vertical movement to the sliding shaft 7 just before the circular motion, a vertical upward force is applied to the lid held by the claws, which prevents the lids from sticking together. In this way, even the first piece of the groove cover can be easily removed in a continuous state with no gaps on the joint surface, and the last piece can be returned smoothly. This is a truly advantageous solution.

In terms of manufacturing, it can be mass-produced at a relatively low cost, and it does not take up much space to store, so it has sufficient potential for general use.
