Description

Technical Field

[0001] This utility model belongs to the technical field of large mining truck ladders, specifically relating to the ladder of the 730E truck. Background Technology

[0002] The ladder on the front of the 730E truck is usually not removable. When a breakdown occurs and the truck needs to be towed, the ladder can easily be squeezed and damaged when the trailer turns. Summary of the Invention

[0003] The purpose of this utility model is to solve the problems existing in the prior art and to provide a ladder for the 730E truck. The ladder is modified to be connected by a hinge at one end and a screw at the other end. When needed, the screw can be removed and one end of the ladder can be lifted up for easy towing.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] The 730E truck ladder includes an upper platform, a ladder body, and a small platform. Its features include: the top of the ladder body is connected to the upper platform via a hinge; the bottom of the ladder body is connected to the small platform via screws. When the truck breaks down and needs to be towed, the screws securing the bottom of the ladder body to the small platform are loosened, and the platform is suspended by ropes. At this time, the ladder body rotates counterclockwise upwards around the hinge axis at a certain angle, preventing the trailer from colliding with the ladder body when turning. The upper platform is fixed to the vehicle body, and the small platform is fixed to the front bumper.

[0006] Compared with the prior art, this utility model has the following advantages:

[0007] The ladder body and the upper platform of this utility model are connected by hinges, and the bottom end of the ladder body is connected to the small platform by screws. When needed, the bottom end of the ladder body can be disassembled and suspended, which is convenient for moving with a trailer in case of failure. Attached Figure Description

[0012] like Figure 1 , Figure 2 and Figure 3 As shown, the 730E truck ladder includes an upper platform 1, a ladder body 2, and a small platform 3. Its features are as follows: the top of the ladder body 2 is connected to the upper platform 1 via a hinge 4; the hinge 4 is connected to the upper platform via hinge fixing screws 4-1; the hinge 4 is welded to the ladder body 2; the bottom of the ladder body 2 is connected to the small platform 3 via screws 2-3; the upper platform 1 is equipped with an upper platform railing 1-1; the ladder body 2 is equipped with a ladder railing 2-1; and the small platform 3 is equipped with a small platform railing 3-1.

[0013] The distance between the outer side of the upper platform railing 1-1 and the front plane of the truck is greater than the distance between the ladder railing 2-1 and the front of the truck, so as to prevent the railing from contacting the ladder body 2 when it is lifted.

[0014] When the truck breaks down and needs to be towed, loosen the screws 2-3 that fix the bottom of the ladder body on the small platform 3, and suspend it with ropes. At this time, the ladder body 2 rotates counterclockwise upwards at a certain angle around the hinge axis, so that the trailer does not collide with the ladder body 2 when turning. The upper platform 1 is fixed to the vehicle body, and the small platform 3 is fixed to the front bumper.
