[0028] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0029] See also Figure 1-5 This embodiment provides a tractor specifically used to pull a cage truck loaded with express parcels. It should be noted that currently all major express delivery companies have express parcel sorting systems. After sorting, express parcels will be delivered to the cage trucks at the corresponding exits. After packaging and loading, the cage trucks will be transferred to the vans for transportation to the next destination. In order to save the transportation volume, the cage trucks are not powered, so they need to be manually pulled to be transferred to the vans. When the express parcels placed on the cage trucks are too heavy, it will be very difficult to pull the cage trucks manually. Based on this, the existing cage trucks are all equipped with tractors, and the tractors pull the cage trucks to move.

[0030] In addition, it should be noted that the existing cage cart has a rectangular frame formed by four cross bars perpendicular to each other at the bottom, and a bottom plate is arranged on the top of the frame. Universal wheels are arranged at the bottom of the four corners of the frame, and a fence is arranged around the edge of the bottom plate on the top of the bottom plate. A storage space with a top opening is formed between the fence and the bottom plate, and the express is placed in the storage space.

[0031] The tractor of the present invention comprises a moving assembly 1 and a lifting assembly 2, wherein the lifting assembly 2 is mounted on the moving assembly 1, and the lifting assembly 2 is used to lift the rear end of the cage car, and the moving assembly 1 is used to drive the cage car to move; the lifting assembly 2 comprises a lifting unit 201 and a lifting block 202, wherein the lifting unit 201 is vertically arranged on the top of the moving assembly 1, and the output end of the lifting unit 201 is connected to the lifting block 202, and is used to control the height of the lifting block 202, and the lifting block 202 is matched with the cross bar at the rear end of the bottom of the cage car, and the cage car can be controlled to move by operating the moving assembly 1. Compared with the steps of the existing tractor pulling the cage car, the operating steps of the operator manually tightening the connecting piece and the cage car are saved, and the problem of the current tractors being fixedly connected to the cage car by providing a connecting piece, and since the connecting piece and the cage car are tightened by manual bolts, the staff needs to match the position of the cage car and the connecting piece, and then manually tighten the bolts, and then operate the tractor to pull the cage car, and this connection method greatly reduces the work efficiency of the staff.

[0032] Furthermore, in order to ensure that the cage car does not separate from the tractor when the tractor is pulling the cage car, the lifting assembly 2 of the present scheme needs to be able to match the cage car with the lifting assembly 2 after completing the lifting of the cage car. Based on this, the top of the lifting block 202 of the present scheme is concave to form a groove for the cross bar at the rear end of the bottom of the cage car to be placed in. The groove width of the lifting block 202 is greater than the width of the cross bar at the bottom of the cage car. It is worth noting that the top opening width of the lifting block 202 of the present scheme is smaller than the length between the diagonals of the cross bars at the bottom of the cage car. The lifting block 202 of this solution is a rectangular tube with an open top. The initial height of the lifting block 202 is lower than the height of the crossbar of the cage car. When the lifting block 202 moves to the bottom of the crossbar of the cage car, the lifting unit 201 controls the lifting block 202 to rise until the lifting block 202 and the crossbar of the cage car are matched. Due to the structural characteristics of the lifting block 202, the lifting block 202 is wrapped around one of the crossbars of the cage car, which is equivalent to the crossbar of the cage car being matched with the lifting block 202 and unable to separate from the tractor alone. Then the lifting assembly 2 continues to control the lifting block 202 to rise, so that the cage car and the lifting block 202 are One end of the cage is lifted, and the two universal wheels that match one end of the bottom of the cage are separated from the ground, while the two universal wheels that match the other end of the bottom of the cage are still slidingly matched with the ground. It should be noted that since the cage is tilted at this time, and the top opening width of the lifting block 202 of this scheme is smaller than the length between the diagonals of the cross bars at the bottom of the cage, after the cage is tilted, there are three points of contact between the lifting block 202 and the cross bar that it matches, corresponding to the three surfaces inside the lifting block 202. This arrangement ensures that the cage will not move relative to the tractor when the tractor is pulling the cage.

[0033] Furthermore, as mentioned above, when one end of the cage car is lifted, there are three points of contact between the lifting block 202 and the cross bar it cooperates with, which correspond to the three surfaces inside the lifting block 202 respectively. Specifically, there are three points between the lifting block 202 and the cross bar it cooperates with, one of which is located at the top of one end of the lifting block 202 close to the cage car. This position can also be understood as the top of one end of the lifting block 202 away from the lifting unit 201. Based on this, in order to improve the force-bearing capacity here, the lifting block 202 of the present scheme is tilted toward the inside of the lifting block 202 away from the top of one end of the lifting unit 201. By changing the mutual resistance angle and force length between one end of the lifting block 202 and the cage car here, the load capacity of the lifting block 202 here is improved.

[0034] Furthermore, as mentioned above, the lifting block 202 needs to be moved to the bottom of the cage car cross bar before the lifting unit 201 can be operated to control the lifting block 202 to rise, thereby realizing the lifting of the cage car cross bar by the lifting block 202. In order to improve the speed and accuracy of the lifting block 202 moving to the bottom of the cage car cross bar, the lifting assembly 2 of the present scheme also includes a positioning block 203, which is arranged on the top of the lifting block 202. The positioning block 203 is used to cooperate with the side wall of the cage car. When the positioning block 203 and the side wall of the cage car are in contact with each other, the lifting block 202 is located just below the cross bar of the cage car.

[0035] Furthermore, the present solution also includes a flexible block 204, which is arranged at one end of the positioning block 203 that abuts against the side wall of the cage car. From top to bottom, the openings of the flexible block 204 and the lifting block 202 do not overlap each other, and the flexible block 204 abuts against the side wall of the cage car. Through such an arrangement, the present solution, firstly, before the lifting assembly 2 lifts the cage car, the purpose of setting the flexible block 204 is to reduce the wear between the positioning block 203 and the cage car. It should be noted that, since the top opening width of the lifting block 202 is greater than the crossbar width at the bottom of the cage car, when the flexible block 204 and the side wall of the cage car fit each other, the positioning block 203 is still just below the crossbar of the cage car. Secondly, after the lifting assembly 2 completes lifting the cage car, the flexible block 204 is still in contact with the side wall of the cage car, so that the tractor of this solution has an additional contact point with the cage car, further ensuring the stability of the cooperation between the tractor and the cage car of this solution.

[0036] Furthermore, the mobile component 1 of the present scheme includes a small wheel unit and a large wheel unit, the small wheel unit includes two front end wheels 101 and a front end connecting piece 102, the two ends of the front end connecting piece 102 are respectively connected to the two front end wheels 101, the large wheel unit includes two rear end wheels 103 and a rear end connecting piece 104, the front end connecting piece 102 is connected to the rear end connecting piece 104 through a connecting piece, and the lifting component 2 is arranged on the front end connecting piece 102. It is worth noting that in order to ensure the normal operation of the device, the height of the front end wheel 101 is lower than the bottom height of the cage car.

[0037] Furthermore, the mobile component 1 of the present solution also includes a drive motor 105, a handle 106 and a control component 107. The drive motor 105 is coaxially connected to any rear end wheel 103, the handle 106 is connected to the rear end connecting component 104, and the control component 107 is coaxially arranged on the handle 106 for controlling the rotation of the drive motor 105.

[0038] Furthermore, the lifting assembly 2 of the present solution further includes a control rod 205 , which is disposed on the handle 106 , and is used to control the lifting movement of the output end of the lifting unit 201 .

[0039] It is worth mentioning that the present solution also includes a lifting status indicator light 3, which is arranged at the top of the handle 106. The lifting status indicator light 3 has three light colors, which respectively correspond to the position of the lifting block 202 being in the lowest state, the position of the lifting block 202 being in the middle state, and the position of the lifting block 202 being in the highest state.

[0040] It should be noted that the present solution has a plurality of lifting blocks 202 , which are evenly spaced on the lifting component 2 along the height direction of the lifting component 2 , and the groove widths of the plurality of lifting blocks 202 are inconsistent so as to adapt to cross bars of different specifications.

[0041] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
