Example 1

[0026] In order to improve the stability of the hydraulic freight elevator, a high-stability hydraulic freight elevator is designed. The specific plan is as follows:

[0027] like Figure 1-3 As shown, a high-stability hydraulic freight elevator includes a base plate 1, four moving wheels 2 are installed at the bottom end of the base plate 1, a lifting structure 4 is provided on the base plate 1, a supporting structure 3 is provided on the base plate 1, the supporting structure 3 includes a connecting seat 301 and a screw rod 303, the top of the base plate 1 is fixedly connected to the connecting seat 301, the connecting seat 301 is rotatably connected to the screw rod 303, two sliders 304 are threadedly connected to the screw rod 303, the sliders 304 are slidably connected to the connecting seat 301, the slider 304 is fixedly connected to the guide shaft 305, the connecting seat 301 is slidably connected to a support plate 308, the bottom end of the support plate 308 is fixedly connected to two guide plates 307, the guide plate 307 is provided with two guide grooves 306, and the two ends of the same guide shaft 305 respectively extend to the inside of the two guide grooves 306 and are slidably connected to the guide plates 307.

[0028] like Figure 3As shown, one end of the screw rod 303 is fixedly connected to the rotating rod 302 , and the rotating rod 302 passes through the screw rod 303 and is perpendicular to the screw rod 303 , so the screw rod 303 can be easily rotated.

[0029] like Figure 3 As shown, the threads at both ends of the screw rod 303 are in opposite directions, and the two sliders 304 are symmetrically distributed about the middle of the connecting seat 301 , so that the two sliders 304 can move in opposite directions during the rotation of the screw rod 303 .

[0030] like Figure 3 and Figure 4 As shown, the middle of the guide groove 306 is inclined, and both ends of the guide groove 306 are horizontally arranged, so when the guide shaft 305 moves at the inclined position in the middle of the guide groove 306, the guide plate 307 can drive the support plate 308 to move toward the ground.

[0031] like Figure 3 and Figure 4 As shown, the support plate 308 penetrates the bottom plate 1 and is slidably connected to the bottom plate 1. The cross section of the end of the support plate 308 is a T-shaped structure, so the contact area between the end of the support plate 308 and the ground can be increased.

[0032] like Figure 1 and Figure 3 As shown, the lifting structure 4 includes a support frame 401 and a hydraulic cylinder 402, two support frames 401 are fixedly connected to the base plate 1, the hydraulic cylinder 402 is installed on the support frame 401, a cross bar 403 is slidably connected to the support frame 401, the extended end of the hydraulic cylinder 402 is fixedly connected to the cross bar 403, and two mounting seats 404 are installed at the bottom end of the cross bar 403, the mounting seats 404 are rotatably connected to guide wheels 405, and a connecting rope 406 is wound around the guide wheel 405, one end of the connecting rope 406 is fixedly connected to a placement plate 407, and the other end of the connecting rope 406 is fixedly connected to the support frame 401, both ends of the placement plate 407 are slidably connected to the two support frames 401, and the support frame 401 is a rectangular frame structure, and the support frame 401 is perpendicular to the base plate 1, so that the goods can be transported.

[0033] like Figure 1 , Figure 3 and Figure 3As shown, two first guardrails 5 are fixedly connected to the top of the placement plate 407, a second guardrail 9 is engaged between the two first guardrails 5, a retaining frame 6 is rotatably connected to one side of the placement plate 407, a connecting sleeve 7 is fixedly connected to one side of the first guardrail 5, and a stopper 8 is fixedly connected to the connecting sleeve 7, the retaining frame 6, the two first guardrails 5 and the second guardrail 9 can be used to resist the goods placed on the placement plate 407, thereby preventing the goods from falling from the placement plate 407 during transportation, thereby improving the safety of use.

[0034] The high-stability hydraulic freight elevator of the present scheme is provided with four moving wheels 2. When in use, the four moving wheels 2 can facilitate the movement of the freight elevator. When the hydraulic freight elevator moves to the designated position, it can rotate the screw rod 303, and the screw rod 303 makes the two sliders 304 move in opposite directions. The slider 304 drives the guide shaft 305 to move inside the guide groove 306. When the guide shaft 305 moves in the inclined position in the middle of the guide groove 306, the two guide plates 307 drive the support plate 308 to slide toward the ground on the connecting seat 301. The screw rod 303 is continuously rotated until the bottom end of the support plate 308 is tightly pressed against the ground. Since the end of the cross-section of the support plate 308 is in a T-shaped structure, the contact area with the ground can be increased. The contact between the support plate 308 and the ground can prevent the freight elevator from moving during loading and unloading of goods, thereby effectively improving the stability of use.

[0035] Instructions for use:

[0036] When in use, the four moving wheels 2 can facilitate the movement of the freight elevator. When it moves to the specified position, the screw rod 303 can be rotated by the rotating rod 302. The screw rod 303 threads drive the two sliders 304 to move in opposite directions. The movement of the slider 304 drives the guide shaft 305 to move inside the guide groove 306. When the guide shaft 305 moves in the inclined position in the middle of the guide groove 306, the two guide plates 307 will drive the support plate 308 to slide toward the ground on the connecting seat 301. The screw rod 303 is continuously rotated until the bottom end of the support plate 308 is tightly pressed against the ground. Since the end of the cross-section of the support plate 308 is in a T-shaped structure, the contact area with the ground can be increased. The contact between the support plate 308 and the ground can prevent the freight elevator from moving when loading and unloading goods, thereby effectively improving the stability of use.

[0037] Then, the goods to be transported can be moved to the placement board 407. When the goods are placed, the blocking frame 6 can be rotated. When one side of the blocking frame 6 contacts the first guardrail 5, the blocking block 8 can be used to block the blocking frame 6. At this time, the blocking frame 6 cannot be rotated. The blocking frame 6, the two first guardrails 5 and the second guardrail 9 can block the goods placed on the placement board 407, thereby preventing the goods from falling off the placement board 407 during transportation, thereby improving the safety of use.

[0038] Then, the two hydraulic cylinders 402 can be started at the same time. The extension of the hydraulic cylinder 402 drives the cross bar 403 to move. The movement of the cross bar 403 will drive the two mounting seats 404 to move. The movement of the mounting seats 404 will drive the guide wheel 405 to move. During the movement of the guide wheel 405, the connecting rope 406 will drive the guide wheel 405 to rotate. At the same time, the four connecting ropes 406 will simultaneously drive the placement plate 407 to move. The movement of the placement plate 407 will drive the movement of the goods, thereby realizing the transportation of the goods. When the goods are transported to the specified height, the hydraulic cylinder 402 will stop extending. At this time, the second guardrail 9 can be removed from the first guardrail 5, so that the second guardrail 9 does not block the goods, thereby facilitating the movement of the goods.
