[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-5 As shown, a labor-saving material transfer device includes: a main support 1, tires 2, a clamping mechanism, and a support mechanism. The tires 2 are rotatably mounted at both ends of the main support 1. An installation platform 3 is fixedly mounted on the top of the main support 1, and a lever 4 is fixedly mounted on the installation platform 3. A suspension rope 5 is fixedly mounted on the left end of the lever 4. A clamping mechanism for gravity clamping of the photovoltaic pier is fixedly mounted at the bottom end of the suspension rope 5, and a support mechanism for auxiliary transfer is fixedly mounted at the front end of the main support 1.

[0028] A toolbox 25 is fixedly installed on the top of the installation platform 3, which is convenient for operators to store commonly used items such as tools and gloves. A handle 26 is fixedly installed on the right end of the lever 4, which is convenient for operators to grip and press down the lever 4.

[0029] In one embodiment, such as Figure 2 and Figure 3 As shown, the clamping mechanism includes a rack 6 fixedly mounted at the bottom end of the suspension rope 5, a sliding bracket 7 located below the suspension rope 5, the rack 6 slidingly mounted on the inner wall of the sliding bracket 7, a limiting plate 8 fixedly mounted at the bottom end of the rack 6, a rubber block 9 fixedly mounted at the top of the limiting plate 8, a gear 10 rotatably mounted on the inner wall of the sliding bracket 7, the rack 6 meshing with the gear 10, a clamping arm 11 fixedly mounted on the periphery of the gear 10, and an adjustment component for adjusting the clamping of photovoltaic piers of different sizes slidably mounted on the clamping arm 11.

[0030] The inner wall of the sliding bracket 7 is provided with a square groove that matches the rack 6. The front and rear sides of the sliding bracket 7 are provided with sliding protrusions that match the square groove. The gear 10 is located on both sides of the rack 6 and meshes with the rack 6 at the same time.

[0031] Align the clamping plates 15 with the two sides of the photovoltaic pier, grasp the handle 26 and press the lever 4 downward. Using the lever principle, the other end will drive the rack 6 to slide upward. The sliding bracket 7 slides downward under the action of gravity. When the rack 6 and the sliding bracket 7 slide relative to each other, the rack 6 drives the gear 10 to mesh and rotate, so that the two gears 10 drive the two clamping arms 11 to clamp towards the middle in sync. Under the action of gravity, the clamping force continuously increases.

[0032] The adjustment assembly includes an adjustment bracket 12 that is slidably mounted on the clamping arm 11. Both the clamping arm 11 and the adjustment bracket 12 are provided with positioning holes 13. An insertion rod 14 is slidably mounted on the inner wall of the positioning hole 13. A clamping plate 15 is fixedly mounted on the bottom of the adjustment bracket 12.

[0033] The operator can adjust the length of the adjusting bracket 12 to match the photovoltaic pier by sliding it on the clamping arm 11, and then insert the insertion rod 14 into the positioning hole 13 located on the clamping arm 11 and the adjusting bracket 12 for locking.

[0034] In one embodiment, such as Figure 4 and Figure 5 As shown, the support mechanism includes a mounting plate 16 fixedly mounted on the front end of the main support 1. A rotating shaft 17 is fixedly mounted on the bottom edge of the mounting plate 16. A threaded rod 18 is rotatably mounted on the rotating shaft 17. Two connecting rods 19 are symmetrically fixed along the circumferential direction on the arc surface of the threaded rod 18, located on the left and right sides of the threaded rod 18 respectively. A locking bracket 20 is fixedly mounted on the bottom end of the connecting rod 19. A sliding rod 21 is slidably mounted on the inner wall of the threaded rod 18 and the locking bracket 20. A universal wheel 22 is fixedly mounted on the bottom end of the sliding rod 21. A threaded sleeve 23 is threadedly connected to the inner wall of the threaded rod 18. A fixing buckle 24 adapted to the sliding rod 21 is fixedly mounted on the mounting plate 16.

[0035] The top of the locking bracket 20 is provided with a pressing ramp that matches the sliding rod 21. A torsion spring is provided at the rotational connection between the rotating shaft 17 and the threaded rod 18. When the lever 4 moves upward, it drives the torsion spring to twist and store force, which facilitates the clamping mechanism to clamp the photovoltaic block. Then the torsion spring drives the threaded rod 18 to reset, which helps the operator to share the pressure. By setting a fixed buckle, the threaded rod 18 can be rotated and stored when not in use. The lower half of the threaded rod 18 is a hollow structure, which facilitates its cooperation with the locking bracket 20.

[0036] By manually adjusting the sliding rod 21 to a suitable length by sliding it along the inner wall of the threaded rod 18, and then turning the threaded sleeve 23, the threaded sleeve 23 and the threaded rod 18 are connected by threads, causing the threaded rod 18 to move downwards when rotating. At the same time, the inner diameter of the threaded rod 18 presses against the compression ramp at the top of the locking bracket 20, causing it to move towards the center, thereby clamping and locking the sliding rod 21. Before performing the clamping operation, the operator can adjust the threaded rod 18 to the predetermined position. When the lever 4 moves upwards, it drives the torsion spring to twist and store force, which facilitates the clamping mechanism to clamp the photovoltaic block. Then, the torsion spring drives the threaded rod 18 to reset, and the universal wheel 22 at the bottom of the sliding rod 21 is released from rolling on the ground, thereby helping the operator to share the pressure.

[0037] The above embodiment discloses a labor-saving material transfer device. The operator aligns the two clamping plates 15 with the sides of the photovoltaic pier, grasps the handle 26, and presses down the lever 4. Using the lever principle, the rack 6 moves upward, while the sliding bracket 7 moves downward synchronously under gravity. The relative sliding between the rack 6 and the sliding bracket 7 forces the gear 10 to mesh and rotate, causing the clamping arms 11 on both sides to contract synchronously towards the center, forming a self-amplifying clamping force that linearly increases with displacement under gravity. An adjusting bracket 12 is provided on the clamping arm 11, which can slide along its length to adapt to the size of the photovoltaic pier. After adjustment, the insertion rod 14 is inserted into the positioning hole 13 of the clamping arm 11 and the adjusting bracket 12 to complete the locking. After manually adjusting the sliding rod 21 to the target length, the threaded sleeve 23 is tightened. Its threaded engagement with the threaded rod 18 drives the threaded rod 18 to move downward. The compression slope of the inner wall of the threaded rod 18 forces the locking bracket 20 to contract towards the center, clamping the sliding rod 21. Before clamping, the threaded rod 18 is pre-adjusted to the working position. When the lever 4 is raised, it is reset by the torsion spring energy storage auxiliary mechanism. After reset, the universal wheel 22 at the bottom of the sliding rod 21 touches the ground and rolls, sharing the weight of the equipment and improving the ease of movement.

[0038] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
