Description

The present invention relates to a transport vehicle for transporting luggage in a premises such as a wholesale market, a factory, or a warehouse, and in particular, provides a transport vehicle having a novel frame structure of an equipment storage room provided at the front of a vehicle body. Is.

The transport vehicle includes a device storage chamber at the front of the vehicle body, and a device that drives a front wheel or the like is stored in the device storage chamber (see, for example, Patent Document 1). FIG. 6 is a side view showing a conventional transport vehicle. As shown in FIG. 6, the transport vehicle is provided with an equipment storage room ES and a cab DS for storing the drive system DR of the front wheels FW and the like at the front part of the vehicle body, and provided in the vehicle body longitudinal direction at the lower part of the vehicle body. A side frame BF is provided. A handle HA for a passenger to steer the front wheel FW is provided at the upper part of the equipment storage room ES, and this handle HA is connected to a drive source DR via a shaft SH extending downward. Further, the side frame BF is provided with a bearing BF for the swivel base CI that rotatably supports the drive source DR, and the front wheels FW are connected to the drive source DR via a power transmission mechanism TR. The equipment storage chamber ES includes a cylindrical side cover SC standing directly on the side frame BF and a plurality of columns SU that support the side cover SC. Then, when the passenger steers the handle HA, the drive source DR and the front wheel FW are turned, and the vehicle body can be steered.
Japanese Patent Laid-Open No. 6-144239, FIG.

By the way, in such a transport vehicle, the rider directly rides on the cab DS and controls the cab DS, so that the cab DS is quickly soiled and the cab DS needs to be washed frequently. According to the transport vehicle described above, since the cab DS and the side cover SC of the equipment storage room are directly attached on the side frame BF, when the cab DS is washed, the cleaning water is operated with the side cover SC. It remains attached to the joint with the base DS. The driver's cab DS is for the driver to ride on and is made of a relatively thick iron plate to withstand the driver's weight, while the side cover SC prevents the front wheel FW drive system from becoming dirty. Therefore, it is composed of a lightweight, relatively thin iron plate.

Therefore, the side cover SC is relatively weak despite being provided near a driver's cab that is frequently cleaned, and thus corrodes early due to the adhering water, thereby causing frequent replacement and cost of maintenance. Becomes very high.

Further, according to the transport vehicle, each support SU is erected on the side frame BF independently, and each support SU is connected and supported by the connecting member extending in the horizontal direction. Therefore, when performing maintenance of the drive source DR in the equipment storage room ES, it is necessary to remove the side cover SC and to perform the removal work for each column SU and each connecting member, which is extremely troublesome and quick. It becomes an important problem for the required maintenance.

Therefore, the present invention is intended to solve these problems, and an object thereof is to provide a new frame structure of a transport vehicle that can prevent early corrosion of a side cover or the like.

The transport vehicle according to the present invention is provided with a front wheel below a device storage chamber provided at a front portion of a vehicle body, a rear wheel is provided below a loading platform mounted on a rear portion of the vehicle body, Left and right side frames provided in the front-rear direction at a predetermined interval in the left-right direction, a front frame provided by connecting the front portions of the side frames, and supporting the equipment storage room, the equipment storage room, and the loading platform And a cab that spans each side frame, and a front frame that is laid across each side frame, the top surface of which is substantially flush with the top surface of the cab, and a floor member A side cover that protects the equipment stored in the equipment storage room from the side through a gap of a predetermined distance from the floor member and the upper surface of the cab. S Characterized in that attached to the over preparative member.

By arranging the side cover of the equipment storage room above the upper surface of the driver's cab and floor member to provide a gap, the cleaning water for cleaning the driver's cab does not adhere to the side cover, so the side cover is prematurely corroded. Can be prevented.

In addition, the device storage chamber is supported by a support member, a side cover that is attached to the support from the outside and protects the device from the side, and a top cover that is disposed above the side cover and protects the device from above. The support column is supported by the support member via a space with respect to the upper surface of the floor member and the cab, and the side cover is attached to the support member via the support column.

By disposing the support column of the equipment storage room above the upper surfaces of the driver's cab and the floor member to provide a gap, the cleaning water does not adhere to the support column and the side cover, so that early corrosion of these can be prevented. Furthermore, by providing a top cover, the upper part of the apparatus can be protected from the washing water.

Preferably, the front wheel is provided with its upper part protruding upward from the upper surface of the floor member and the cab, and the support member is provided so as to cover the upper part of the front wheel and to the upper surface of the floor member and the cab. A support member is provided projecting outward from the outer surface through the gap, and the support column is supported by the support member.

The cab can be lowered by projecting the front wheels upward from the upper surface of the cab, so that it is possible to easily get on and off the transport vehicle, and the front wheels are covered with a support member, so that mud from the front wheels can be obtained. Since it is possible to prevent splashes and the like from climbing up to the cab, cleaning effort and corrosion can be suppressed.

A plurality of support columns are provided along the outer periphery of the support member, and two adjacent columns are connected via a connection member. Furthermore, the holding member which hold | maintains the distribution line to the apparatus accommodated in the apparatus storage chamber is provided in the connection member distribute | arranged to the position closest to the vehicle body among connection members.

Rigidity can be improved by connecting two adjacent struts via a connecting member, and the equipment storage chamber can be firmly protected. Furthermore, by holding the distribution line at the position closest to the front of the vehicle body, it is possible to distribute the distribution line at a position away from the cab, so that the influence of dirt from the cab can be minimized, and an important distribution line. Can be held firmly, and dangers such as electric leakage can be prevented. In addition, by fixing the position of the distribution line with the holding member, the distribution line is not caught in a drive source that turns in the equipment storage chamber.

As described above, according to the present invention, early corrosion of the side cover can be prevented, and important distribution lines can be firmly guarded.
