Description

Technical Field

[0001] The utility model relates to the technical field of loading and unloading two containers onto a skeleton type semi-trailer through a hook truck, in particular to a garbage transfer box with longitudinal beam self-locking rollers. Background Art

[0002] The problems existing in the prior art are:

[0003] If the existing garbage transfer box is placed on the trailer by a hook truck, a track must be laid on the trailer where the transfer box roller passes, so that the box roller can move on the track. The problems of placing the box on the trailer are:

[0004] (1) Installing tracks on trailers does not comply with vehicle manufacturing regulations;

[0005] (2) In order to move the transfer box on the trailer, it is necessary to lay rails on the track. The transfer box is heavy, so the track must be strengthened, which increases the weight of the trailer itself and reduces the effective loading mass of the trailer;

[0006] (3) When the transfer boxes are different and the wheelbases of the rear wheels of the transfer boxes are different, the tracks to which the running wheels of the boxes are attached are different. In this way, the versatility of the trailer is greatly limited. Summary of the invention

[0007] The utility model aims to overcome the deficiencies of the prior art and provide a garbage transfer box with longitudinal beam self-locking rollers, which can be placed on a trailer by a hook truck without modifying the skeleton semi-trailer.

[0008] The purpose of the utility model is achieved in this way:

[0009] A garbage transfer box with longitudinal beam self-locking rollers, comprising a transfer box body, two longitudinal beams parallel to each other are symmetrically arranged at the bottom of the transfer box body, two running wheels are arranged at the rear end of the bottom of the transfer box body, the two running wheels are symmetrically located on both sides of the two longitudinal beams, the bottom ends of the two running wheels are lower than the lower surface of the longitudinal beams, the rear ends of the two longitudinal beams are respectively fixed with mounting seats, the rear bottom ends of the mounting seats are provided with mounting grooves, longitudinal beam self-locking rollers are arranged in the mounting grooves, the longitudinal beam self-locking rollers are installed on the mounting seats through roller shafts, the outer wheel rim ends of the longitudinal beam self-locking rollers are tangent to the lower surface of the longitudinal beams, or the outer rim bottom ends of the longitudinal beam self-locking rollers are higher than the lower surface of the longitudinal beams, and the rear ends of the longitudinal beam self-locking rollers protrude from the rear end surface of the longitudinal beams;

[0010] When the hook box of the hooklift truck is loaded, the front part of the transfer box is in a raised state, the self-locking rollers of the longitudinal beam are supported on the frame semi-trailer beam, and the longitudinal beam is separated from the frame semi-trailer beam;

[0011] When the garbage transfer box is loaded and straightened, the self-locking rollers of the longitudinal beam are separated from the frame semi-trailer frame, the longitudinal beam contacts the frame semi-trailer frame to form static friction, and the transfer box body is in a locked state.

[0012] Preferably, the mounting seat is welded and fixed to the rear ends of the two longitudinal beams, the lower surface of the mounting seat is higher than the lower surface of the longitudinal beam, and the bottom end of the longitudinal beam self-locking roller protrudes from the lower surface of the mounting seat.

[0013] Preferably, the installation spacing of the self-locking rollers of the longitudinal beam is consistent with the spacing position of the frame semi-trailer beams specified in the national standard.

[0014] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0015] 1. The running wheels of the garbage transfer box and the self-locking rollers of the longitudinal beam perform their respective functions without interfering with each other. The installation spacing of the self-locking rollers of the longitudinal beam is consistent with the spacing of the vehicle beams specified in the national standard. Therefore, this method of movement has strong versatility;

[0016] 2. Due to the installation of self-locking rollers on the longitudinal beam, there is no need to modify the skeleton semi-trailer, and the box can be rolled and moved on the trailer under the action of the hook truck to place the box;

[0017] 3. If there is no self-locking roller on the longitudinal beam, and the garbage transfer box moves by the walking wheels, a new track must be built on the trailer. On the one hand, the weight of the trailer itself will increase, thereby reducing the effective load capacity. On the other hand, there is a suspicion of illegal modification of the special vehicle.

[0018] 4. In the past, gantry cranes, reach stackers and other equipment were mainly used to load and unload garbage transfer boxes onto trailers. The equipment had poor versatility and high equipment investment. The use of a hook truck with strong versatility, no site requirements, and powerful functions (which can transfer boxes in garbage stations and load and unload boxes onto trailers) will further reduce equipment investment and operating costs.
