Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to a self-guiding roller device for the longitudinal beam of a detachable garbage bin. Background Art

[0002] A garbage station is a place for storing or recycling garbage. A garbage collection vehicle will collect the garbage generated in living areas such as surrounding communities and factories, and transport the collected garbage to a garbage transfer box (a pull-arm hook box) for storage. Then, a semi-trailer will transport the garbage stored in the garbage transfer box to a garbage treatment plant or a landfill for treatment.

[0003] For the existing garbage transfer box, if a pull-arm hook vehicle is used to place the box on a semi-trailer, it is necessary to set up a box placement and pulling box limit track on the semi-trailer to enable the transfer box to move on the semi-trailer track through the bottom rollers and be placed at a preset position. The existing problems include: 1. Installing a limit track on the semi-trailer does not meet the requirements of vehicle modification regulations; 2. In order to move and place the transfer box on the semi-trailer, it is necessary to lay a track on the girder. Since the transfer box is relatively heavy, the track needs to be strengthened, which increases the weight of the trailer itself and reduces the effective loading mass of the trailer; 3. For transfer boxes manufactured by different manufacturers, the wheelbase of the bottom rollers is not of a unified size, and the tracks on which the walking wheels of the box body rely will be different, greatly limiting the versatility of the trailer. Summary of the Utility Model

[0004] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the utility model is how to provide a self-guiding roller device for the longitudinal beam of a detachable garbage bin with a simpler and more reasonable structural design, which can rely more on the original structure of the skeleton semi-trailer to complete the guiding and loading, and can reduce the weight and improve the transportation capacity.

[0005] To achieve the above object, the utility model provides a self-guiding roller device for the longitudinal beam of a detachable garbage bin, which is characterized in that: it includes two longitudinal beams arranged at intervals along the transverse direction of the transfer box body on the bottom surface of the transfer box body. At the front end of the longitudinal beam, a guiding roller is rotatably installed vertically through an installation bracket, and the lower surface of the guiding roller is located below the lower surface of the longitudinal beam; the guiding roller is integrally designed in a conical structure with a larger inner diameter and a smaller outer diameter; and the distance between the two guiding rollers is matched with the two longitudinal girders on the skeleton semi-trailer; when the pull-arm hook vehicle drives the transfer box body to move longitudinally on the skeleton semi-trailer for loading, the two guiding rollers can roll and cooperate on the two girders to complete the guiding.

[0006] In this way, in the above structure, by arranging two longitudinal beams on the bottom surface of the transfer box, and then installing and setting guiding rollers at the front ends of the longitudinal beams through mounting brackets, and designing the guiding rollers as a conical structure as a whole, and making the distance between the two guiding rollers match the two longitudinal girders on the skeletal semi-trailer; when the pulling arm hook vehicle drives the transfer box body to move longitudinally on the skeletal semi-trailer for loading, the two guiding rollers can roll and cooperate on the two girders to complete guiding. Due to the conical structure design of the guiding rollers, it has a self-centering effect. And the distance between the guiding rollers conforms to the distance position of the girders of the skeletal semi-trailer specified by the national standard, which makes it have better versatility. Secondly, it can rely more on the original structure of the skeletal semi-trailer to complete the guiding loading, reducing the modification of the semi-trailer, reducing the addition of extra components, and being able to reduce the weight and improve the transportation capacity.

[0007] As an optimization, the girder includes a support backing plate with an overall elongated structure design above; a limiting block with an L-shaped structure design is arranged at the front end of the support backing plate.

[0008] In this way, by setting the support backing plate, it can play a role in protecting the girder; and setting the limiting block can play a role in limiting the transfer box.

[0009] As an optimization, the guiding roller includes a limiting shoulder section at the inner end; and the distance dimension between the two outer end faces of the two limiting shoulder sections is set to be less than or equal to the distance dimension between the two inner side faces of the two support backing plates.

[0010] In this way, the set limiting shoulder section can play a role in restricting the axial position of the guiding roller, making the guiding roller better cooperate with the support backing plate.

[0011] As an optimization, chamfer structures are respectively arranged on the two outer end faces of the limiting shoulder section.

[0012] In this way, by setting the chamfer structures on the limiting shoulder section, the design is more reasonable.

[0013] As an optimization, the guiding roller includes a guiding column section integrally formed at the outer end outside the limiting shoulder section, and the guiding column section is designed as a conical structure with a larger inner diameter and a smaller outer diameter; and the distance dimension between the two outer end faces of the two guiding column sections is set to be less than or equal to the distance dimension between the two outer side faces of the two support backing plates.

[0014] In this way, the structural design of the guiding roller is more reasonable, and the designed guiding column section can better complete the guiding.

[0015] As an optimization, the mounting bracket includes a cushion block disposed on the inner side surface of the front end of the longitudinal beam. On the outer side surface of the cushion block and the outer side surface of the front end of the longitudinal beam, a bracket plate disposed forward is fixedly connected respectively. Between the outer ends of the two bracket plates, the guiding roller is mounted through a mounting shaft.

[0016] In this way, the structural design of the mounting bracket is simpler and more reasonable, and can better install the guiding roller.

[0017] As an optimization, at the front end of the bottom surface of the transfer box body and at the outer side positions of the two guiding rollers, a first locking block is mounted respectively. On the girder, a first locking mechanism is provided corresponding to the first locking block respectively; at both sides of the rear end of the lower surface of the transfer box body, a second locking block is provided respectively; and at the rear end of the girder, a cross beam is provided. On the cross beam, a second locking mechanism is provided corresponding to the second locking block respectively.

[0018] In this way, after the transfer box moves into place, it can be better fixed to ensure the stability during transportation.

[0019] As an optimization, at the front end of the bottom surface of the transfer box body and at intervals along the transverse direction, two walking wheels are provided, and the two walking wheels are located outside the two guiding rollers.

[0020] In this way, by providing the walking wheels, the transfer box can be better moved on flat ground.

[0021] To sum up, the above device has the characteristics that the structural design is simpler and more reasonable, can more rely on the original structure of the skeleton semi-trailer to complete the guiding and loading, and can reduce the weight and improve the transportation capacity.
