JPS5826865Y2 - Box-shaped loading platform structure for power transport vehicles - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a box-shaped loading platform structure for a power carrier that transports and throws earth and sand while loading it.

The opening/closing lid for the loading platform of the power transport vehicle remains closed when the loading platform is in the normal position, but opens automatically when the loading platform rises and becomes slanted to throw away dirt, etc.

When loading long objects on a loading platform, the opening/closing lid must be removed before transportation, so the opening/closing lid is detachable from the side lid. In order to fit the mounting pin of the opening/closing lid, a hole with an opening was provided in the support plate of the side lid, and the opening of the hole with the opening was kept open at all times. This made opening and closing operations difficult.

Therefore, the purpose of this invention is to eliminate the above-mentioned drawbacks and to facilitate the transportation of dirt, etc. by providing a fitting body that prevents the intrusion of dirt, etc. into the hole opening of the support plate of the side cover into which the mounting pin fits. It is something to do.

The mode of implementation of the present invention will be described in detail below with reference to illustrative drawings. 1 is a machine frame body of a power carrier placed on the upper part of a crawler type traveling device 2, and a box-shaped loading platform frame 3 is equipped on the front part so as to be freely tiltable. It is equipped with a prime mover 4 and a driver's seat 5.

Reference numeral 6 denotes a hydraulic cylinder interposed between the lower part of the carrier frame 3 and the lower part of the machine frame main body 1, and by its extension operation, the carrier frame 3 can be raised and tilted as shown by the imaginary line in FIG.

Reference numeral 7 denotes a fulcrum pin that connects the front end of the machine frame body 1 and the front end of the loading platform frame 3.

Further, in FIG. 2, reference numeral 8 denotes an opening/closing lid provided on the front side of both side lids 9, 9 of the loading platform frame 3, and has shaft-shaped mounting pins 10.degree. 10 protruding from both upper sides a9a.

The distal end of the mounting pin 10 has notches 11 on both sides.
, 11 are provided to form the narrow portion A.

12 is a mounting plate that fixes the mounting pin 10; 13 is a loading platform frame 3;
Fitting hole 1 is fixed to the front upper part of both lids 9, 9.
4, and as shown in FIG. 4, the mounting pin 10 is fitted and supported so that the opening/closing etc. 8 can be hung freely.

The fitting hole 14 of the support plate 13 is provided with an opening 15 in the narrow portion B, as shown in FIG.

Reference numeral 16 denotes a fitting body loosely fitted onto the mounting pin 10, and a fitting piece 17 integrally protruding from the support plate 130 is fitted into the end portion 15 of the support plate 130 to close it.

The present invention has the above-mentioned configuration, and therefore, when the opening/closing lid 8 is attached to the front end of the loading platform frame 3, the opening/closing lid 8 is
Lift it up and position it in a substantially horizontal position, and insert the narrow part A of the mounting pin 100 of the opening/closing lid 8 into the opening 15 of the narrow part B of the support plate 130 as shown in FIG. 5, and move it sequentially forward. Completely fit into the fitting hole 14.

Further, the fitting piece of the fitting body 16 provided on the mounting pin 10 fits into the opening 15 and closes it.

As shown in FIG. 2, the entire opening/closing lid 8 is made of gold.

Moreover, when removing the opening/closing lid 8, it can be easily removed by lifting the opening/closing lid 8 and pulling it out rearward, contrary to the above.

As described above, according to the present invention, shaft-shaped mounting pins with small diameter notches are provided protrudingly on both sides of the upper part of the opening/closing lid of the loading platform, and the mounting pins are fitted with support plates fixed to the upper parts of both lids of the loading platform. In a case where the entire opening/closing lid is made of metal by fitting into the hole, a narrow opening is provided inwardly in the fitting hole of the support plate to allow the mounting pin to be engaged and removed, and the support plate is inserted into the mounting pin. Since the fitting body, in which the fitting body piece that fits into the opening is integrally protruded, is rotatably mounted, the fitting body can always fit into and close the opening of the support plate.

There is no possibility that dirt or the like will enter the opening, and wear of the mounting pins can be prevented, so that the lid can be opened and closed smoothly at all times.
