Description
The technical field is as follows:
the utility model belongs to the technical field of the semitrailer technique and specifically relates to a low flat-bed semitrailer cat ladder convenient to maintenance.
Background art:
a semitrailer is a transportation tool for connecting a trailer with a traction vehicle head through a traction pin. In order to obtain larger bearing capacity, semi-trailers are mainly two-axle or three-axle semi-trailers, and the semi-trailers can be classified into a warehouse-rail semi-trailer, a low-bed semi-trailer and the like.
The body part of the low-flat-plate semitrailer is not provided with a baffle plate, is usually used for loading and transporting small and medium-sized vehicles, excavators, forklifts, harvesters and the like, and is suitable for long-distance transportation of engineering machinery and other large and heavy-load goods which cannot be disassembled. In order to facilitate various self-propelled equipment (such as excavators, harvesters and the like) to get on and off, a left ladder climbing device and a right ladder climbing device are additionally arranged at the tail parts of a plurality of trailers. With the ladder stand device, various self-propelled equipment can get on and get off along the ladder stand by oneself, so that the trouble of using a crane is avoided, and the use cost is reduced. But at the same time, because of the heavy structure, the ladder is difficult to maintain when the ladder breaks down.
The invention content is as follows:
for solving the problem, overcome the not enough of prior art, the utility model provides a low flat-bed semitrailer cat ladder of the maintenance of being convenient for of simple structure, the maintenance of being convenient for.
In order to achieve the purpose, the utility model provides a low flat-bed semitrailer ladder convenient to maintain, which comprises a frame, wherein the tail end of the frame is hinged with two ladders; the tail end of the frame is also hinged with an oil cylinder, and the other end of the oil cylinder is hinged with the middle part of the ladder stand; the upper surface of cat ladder is provided with the panel, is provided with the maintenance mouth on the panel.
Furthermore, a sealing plate is arranged on the maintenance port, an insertion groove is formed in one end of the maintenance port, a connecting plate is arranged at the other end of the maintenance port, an insertion plate is arranged at the position, corresponding to the insertion groove, of the sealing plate, and the insertion plate is arranged in the insertion groove in a pluggable mode.
Furthermore, the closing plate is connected with the connecting plate through a bolt.
Furthermore, the lower part of the ladder stand is hinged with a support leg.
Further, the cat ladder sets up to two segmentation structures, and the both ends cat ladder is connected through articulated mode.
The beneficial effects of the utility model are that:
the utility model provides a low flat-bed semitrailer cat ladder convenient to maintenance has that structural strength is big, the difficult seepage polluted environment's advantage, and the upper surface of cat ladder is provided with the panel, is provided with the maintenance mouth on the panel, can directly maintain the various structures at the cat ladder back through the maintenance mouth, has solved the condition of maintenance difficulty.
When normally using, the shrouding fixed mounting can not influence its use on the cat ladder. When inner structure broke down, can dismantle down the shrouding, maintain inner structure, maintain from upper portion simultaneously, space and operable scope are bigger, can improve maintenance efficiency, improve the maintenance environment.
Description of the drawings:
FIG. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic structural view of a maintenance opening of the present invention;
in the drawings: 1. the frame, 2, cat ladder, 3, panel, 4, maintenance mouth, 5, landing leg, 6, hydro-cylinder.
The specific implementation mode is as follows:
in order to make the purpose, technical solution and advantages of the present invention clearer, the following will combine the attached figure 1 of the present invention to perform more detailed description of the present invention.
The utility model provides a low flat-bed semitrailer ladder 2 convenient to maintain, which comprises a frame 1, wherein two ladders 2 are hinged at the tail end of the frame 1; the tail end of the frame 1 is also hinged with an oil cylinder 6, and the other end of the oil cylinder 6 is hinged with the middle part of the ladder stand 2; a panel 3 is arranged on the upper surface of the ladder stand 2, and a maintenance opening 4 is arranged on the panel 3; a sealing plate is arranged on the maintenance port 4, an inserting groove is formed in one end of the maintenance port 4, a connecting plate is arranged at the other end of the maintenance port 4, an inserting plate is arranged at the position, corresponding to the inserting groove, of the sealing plate, and the inserting plate is arranged in the inserting groove in an inserting mode; the sealing plate is connected with the connecting plate through a bolt; the lower part of the ladder stand 2 is hinged with a support leg 5; the ladder stand 2 is arranged into a two-section structure, and the ladder stands 2 at two ends are connected in a hinged mode.
The utility model discloses a one of them embodiment as follows:
low flatbed semitrailer cat ladder 2 convenient to maintenance, including frame 1, the tail end of frame 1 articulates there are two cat ladders 2, for improving availability factor, makes things convenient for various vehicles from top to bottom, and cat ladder 2's width is bigger, and frame 1's tail end still articulates there is hydro-cylinder 6, and hydro-cylinder 6's the other end is articulated with cat ladder 2's middle part, packs up and sets level through hydro-cylinder 6 drive cat ladder 2.
