[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] The following is an explanation of the preferred embodiments of the device of the utility model.

[0030] See also Figure 1-5 As shown, the movable unloading platform includes a base 1, a cargo platform 2 and a vertical plate 7. The base 1 is symmetrically arranged with two groups. The bases 1 on both sides are connected and fixed as a whole by supporting plates 101. A horizontal plate 102 is horizontally arranged on the rear side of the base 1. Positioning members 5 are arranged at both ends of the outer side of the horizontal plate 102. The vertical plates 7 are fixedly installed on the opposite sides of the bases 1 on both sides. The cargo platform 2 is slidably connected with the inner grooves formed by the vertical plates 7 on the base 1. A turntable 3 is provided on the upper end surface of the cargo platform 2, and a fixing component 4 is provided on the turntable 3. A guide groove 201 is provided along the periphery of the turntable 3 of the cargo platform 2, and side frames 202 are installed on both sides of the cargo platform 2. Slide blocks 17 sliding in the inner grooves of the vertical plates 7 are fixedly connected to the outer sides of the side frames 202 on both sides, and second mounting plates 16 are fixedly connected to the outer sides of the side frames 202. The front and rear ends of the cargo platform 2 are movably connected with receiving plates 203.

[0031] Furthermore, a mounting frame 8 is connected to the outer side of the vertical plate 7 toward the rear side of the base 1, and the side portions of the mounting frames 8 on both sides are connected as a whole via a connecting plate 9. A first mounting plate 10 is installed on the connecting plate 9, and a guide wheel 11 is movably connected to the upper end surface of the first mounting plate 10. A fixing block 15 is provided on the outer surface of the mounting frame 8 close to the vertical plate 7.

[0032] Furthermore, mounting blocks 6 are symmetrically provided on the outer sides of the bases 1 on both sides, and a hydraulic telescopic rod 12 is inserted into the mounting block 6. A sprocket 13 is installed on the upper end of the output end of the hydraulic telescopic rod 12, and a chain 14 is wrapped around the outer surface of the sprocket 13. One end of the chain 14 is fixed to the fixing block 15, and the other end of the chain 14 is fixed to the second mounting plate 16.

[0033] Furthermore, the rear receiving plate 203 of the cargo platform 2 abuts against the inner side of the connecting plate 9 .

[0034] Furthermore, moving wheels 18 are installed at the front and rear ends of the bottom of the base 1.

[0035] Specifically, the receiving plate 203 at the front end of the cargo platform 2 is naturally overlapped with the ground to form a smooth transition bridge, and then the cargo is pushed onto the cargo platform 2 through the external pushing mechanism, and the cargo is fixed by the setting of the fixing component 4, and the device is moved to the rear of the loaded vehicle through the moving wheel 18, and the position is fixed by the positioning member 5, and then the hydraulic telescopic rod 12 is started, and its output end drives the sprocket 13 to rotate, thereby driving the chain 14 to move, one end of the chain 14 is fixed to the fixing block 15, and the other end is fixed to the second mounting plate 16, so that as the chain 14 moves, the cargo platform 2 will move along the vertical The groove on the inner side of the plate 7 slides up or down, and the hydraulic telescopic rod 12 is activated to drive the cargo platform 2 to rise above the height of the guide wheel 11. At this time, the receiving plate 203 abutting the rear end will naturally fall to the top of the guide wheel 11, and the rear receiving plate 203 overlaps with the rear end of the truck to form a smooth transition bridge. The fixing component 4 is then rotated by the turntable 3, and the opening direction of the fixing component 4 is changed with the assistance of the guide block 410 sliding along the guide groove 201, so that the goods fixed on the fixing component 4 are directed toward the rear end of the truck, and then pushed again by the external pushing mechanism to deliver the goods to the loaded truck compartment. The operation is simple.

[0036] It should be further explained that the height of the guide wheel 11 can be adjusted to be flush with the truck compartment.

[0037] In another embodiment provided by the present invention, Figure 4 and 5 As shown, the fixing assembly 4 includes a bearing plate 401, a fixing rod 402, an arc frame 403, a right-angled opening 404, a mounting sleeve 405, a fixing plate 406, a first spring buffer rod 407, a second spring buffer rod 408 and a pressing plate 409. The bearing plate 401 is arranged on the upper end surface of the turntable 3 and is symmetrical about the axis of the turntable 3. The fixing rod 402 is installed on the top of the bearing plate 401. The upper and lower ends of the outer surface of the fixing rod 402 are connected to the arc frame 403. The arc frame 403 A right-angle opening 404 is correspondingly opened on the inner side, and the upper outer surfaces of the symmetrical fixing rods 402 are sleeved with mounting sleeves 405, and fixing plates 406 are provided on the opposite sides of the mounting sleeves 405 on both sides, and the fixing plates 406 are correspondingly provided with first spring buffer rods 407 and second spring buffer rods 408. The first spring buffer rods 407 and the second spring buffer rods 408 are distributed in two groups up and down, and the opposite sides of the first spring buffer rods 407 and the second spring buffer rods 408 on both sides are connected with pressure plates 409.

[0038] Furthermore, the fixing assembly 4 further includes a guide block 410 , and the guide block 410 slides in the guide groove 201 .

[0039] Furthermore, the length of the first spring buffer rod 407 is shorter than that of the second spring buffer rod 408 , and the pressure plates 409 on both sides are in an eight-shaped shape.

[0040] Specifically, when the cargo is pushed to the cargo platform 2, the cargo first contacts the pressure plate 409. Due to the eight-shaped setting of the pressure plate 409, the cargo will squeeze the pressure plate 409. As the cargo squeezes the pressure plate 409, the first spring buffer rod 407 is compressed first. Due to its short length, the first spring buffer rod 407 can provide a quick response, absorb a portion of the impact force of the cargo, and provide preliminary buffering for the subsequent fixing process. As the pressure of the cargo continues to be applied, the second spring buffer rod 408 also begins to be compressed. Due to its long length, the pressure plate 409 is tilted, and the second spring buffer rod 408 can provide a larger buffer stroke, further absorb the impact force of the cargo, and generate a larger pressure. Under the joint action, the pressure plates 409 on both sides begin to gradually shrink from an eight-shaped shape to a parallel line shape. During this process, the contact area between the pressure plates 409 and the goods gradually increases until it finally fits horizontally to the outer surface of the goods. When the pressure plates 409 are completely in contact with the outer surface of the goods, the pressure of the first spring buffer rod 407 and the second spring buffer rod 408 act on the goods together to ensure that the goods are subjected to uniform restraint force in the horizontal direction, and then continue to push the goods to make them contact with the arc frame 403, and make the corner edge of the goods embedded in the right-angle opening 404. The setting of the right-angle opening 404 further increases the restraint force on the goods and enhances the fixing effect of the entire fixing component 4 on the goods. This design not only improves the stability of the goods, but also reduces the risk of damage to the goods due to shaking or displacement during transportation.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
