Description

Technical Field

[0001] This utility model relates to the field of lifting tool technology, specifically to a lifting tool used in the production of air conditioning refrigeration components. Background Technology

[0002] Lifting tools commonly used include specialized rigging such as hooks, wire ropes, and chains. Lifting suction cups, clamps, and forks can be used permanently as dedicated lifting tools on cranes, or as replaceable auxiliary lifting tools attached to hooks for temporary use. Lifting tools used in the production of air conditioning and refrigeration components are mainly used for lifting, transporting, and installing various equipment and components in air conditioning systems. These lifting tools typically need to have strong load-bearing capacity and durability to ensure the safe lifting and positioning of components during the production process, improving production efficiency and reducing operational risks.

[0003] In the prior art, such as the Chinese patent with publication number CN212832503U entitled "A Lifting Device for the Production of Air Conditioning Refrigeration Components," the disclosed technical solution describes a device that adjusts the height of the top plate via an electric push rod to change the lifting height of the components; it also uses suction cups to contact and adhere to the ground, fixing the entire lifting device and preventing movement when the components are placed. However, while this device can prevent movement by suspending the air conditioning refrigeration components on the hook, the components may still sway on the hook, potentially leading to them falling off or being damaged during subsequent transportation and processing. Utility Model Content

[0004] This utility model provides a lifting tool for the production of air conditioning refrigeration components to solve the above-mentioned problems.

[0005] This utility model adopts the following technical solution: a hoist for the production of air conditioning refrigeration parts, including a mounting frame and a suspension mechanism; a hydraulic telescopic rod is fixedly installed on the mounting frame, and a lifting plate is fixedly installed on the upper end of the hydraulic telescopic rod, with a sliding groove provided on the lifting plate; the suspension mechanism includes a sliding block, a hook, a clamping assembly, and a limiting assembly; multiple sliding blocks are provided, and the multiple sliding blocks are slidably installed in the sliding groove; the hook is fixedly installed at the lower end of the sliding block; the clamping assembly is located at the lower end of the sliding block and is used to prevent the refrigeration parts from swaying on the hook; the limiting assembly is located on the sliding block and is used to limit the sliding block; the hydraulic telescopic rod extends and retracts to drive the lifting plate to rise and fall, and the height of the lifting plate is adjusted to adapt to the height of different refrigeration parts; the distance between the multiple sliding blocks is adjusted according to the width of the refrigeration parts; and the refrigeration parts are suspended on the hook.

[0006] Furthermore, the clamping assembly includes a mounting plate, a bidirectional screw, and clamping plates; the mounting plate is fixedly mounted on the lower end of the sliding block; the bidirectional screw is rotatably mounted on the mounting plate, with the threads at both ends of the bidirectional screw rotating in opposite directions; two clamping plates are provided, symmetrically arranged on both sides of the hook, and the clamping plates are threaded onto the bidirectional screw; a rotating handle is fixedly mounted on one end of the bidirectional screw; after the refrigeration component is suspended on the hook, rotating the bidirectional screw by rotating the handle causes the clamping plates on both sides of the hook to move closer to each other, clamping the refrigeration component and preventing it from swaying on the hook.

[0007] Furthermore, the limiting assembly includes a guide rod and a limiting screw; the guide rod is fixedly installed in the sliding groove, and the sliding block and the guide rod are slidably connected; a limiting screw is threaded onto the sliding block, and a limiting block is rotatably installed at the lower end of the limiting screw; a limiting groove is formed at the lower end of the limiting block, and a friction plate is fixedly installed in the limiting groove; rotating the limiting screw causes the limiting screw to drive the limiting block to move downward, thereby causing the limiting groove and the guide rod to abut against each other, thus fixing the sliding block.

[0008] Furthermore, a caster wheel is fixedly installed at the lower end of the mounting frame; a first screw is rotatably installed on the mounting frame, and a suction cup is rotatably installed at the lower end of the first screw; the caster wheel facilitates the movement of the entire lifting device; when it needs to be fixed, the first screw is rotated to make the suction cup adhere to the ground.

[0009] The beneficial effects are: after the refrigeration parts are suspended on the hook, turning the handle causes the double-ended screw to rotate, thereby driving the clamps on both sides of the hook to move closer to each other and tighten the refrigeration parts, effectively fixing the suspended refrigeration parts and preventing them from falling off or being damaged due to shaking during transportation or processing.

[0010] The lifting plate is driven to rise and fall vertically by a hydraulic telescopic rod, and the sliding block slides in the sliding groove to adjust the spacing, so that the lifting device can adapt to refrigeration components of different heights and widths, thus improving its versatility.

[0018] An embodiment of a lifting fixture for the production of air conditioning refrigeration components according to this utility model, such as... Figures 1 to 4 The image shows a hoist used in the production of air conditioning refrigeration components, comprising a mounting frame 100 and a suspension mechanism. A hydraulic telescopic rod 110 is fixedly mounted on the mounting frame 100, and a lifting plate 120 is fixedly mounted on the upper end of the hydraulic telescopic rod 110. The lifting plate 120 has a sliding groove 121. The suspension mechanism includes a sliding block 200, a hook 210, a clamping assembly, and a limiting assembly. Multiple sliding blocks 200 are provided and are slidably installed in the sliding groove 121. The hook 210 is fixedly installed at the lower end of the sliding block 200. The clamping assembly is located at the lower end of the sliding block 200 and is used to prevent the refrigeration component from swaying on the hook 210. The limiting assembly is located on the sliding block 200 and is used to limit the sliding block 200. The extension and retraction of the hydraulic telescopic rod 110 drives the lifting plate 120 to rise and fall, adjusting the height of the lifting plate 120 to adapt to the height of different refrigeration components. The distance between the multiple sliding blocks 200 is adjusted according to the width of the refrigeration component. The refrigeration component is then suspended on the hook 210.

[0019] The clamping assembly includes a mounting plate 201, a bidirectional screw 220, and a clamping plate 230. The mounting plate 201 is fixedly mounted on the lower end of the sliding block 200. The bidirectional screw 220 is rotatably mounted on the mounting plate 201, and the threads at both ends of the bidirectional screw 220 rotate in opposite directions. There are two clamping plates 230, which are symmetrically arranged on both sides of the hook 210 and threaded onto the bidirectional screw 220. A rotating handle 221 is fixedly mounted on one end of the bidirectional screw 220. After the refrigeration component is suspended on the hook 210, the bidirectional screw 220 is rotated by rotating the handle 221 to bring the clamping plates 230 on both sides of the hook 210 closer together, clamping the refrigeration component and preventing it from swaying on the hook 210.

[0020] The limiting assembly includes a guide rod 240 and a limiting screw 250. The guide rod 240 is fixedly installed in the sliding groove 121, and the sliding block 200 is slidably connected to the guide rod 240. The limiting screw 250 is threadedly installed on the sliding block 200, and a limiting block 251 is rotatably installed at the lower end of the limiting screw 250. A limiting groove 252 is opened at the lower end of the limiting block 251, and a friction plate is fixedly installed in the limiting groove 252. Rotating the limiting screw 250 causes the limiting screw 250 to drive the limiting block 251 to move downward, thereby causing the limiting groove 252 and the guide rod 240 to abut against each other, thus fixing the sliding block 200.

[0021] The mounting bracket 100 is fixedly mounted with casters 130 at its lower end; a first screw 140 is rotatably mounted on the mounting bracket 100, and a suction cup 150 is rotatably mounted at the lower end of the first screw 140; the casters 130 facilitate the movement of the entire lifting device; when it is necessary to fix it, the first screw 140 is rotated to make the suction cup 150 adhere to the ground.

[0022] Based on the above embodiments, the working principle and process of this utility model are as follows: After moving the entire lifting device to the working position using the universal wheels 130, the first screw 140 is rotated to make the suction cup 150 adhere to the ground; the hydraulic telescopic rod 110 extends and retracts, driving the lifting plate 120 to rise and fall, adjusting the height of the lifting plate 120 to adapt to the height of different refrigeration components; the distance between multiple sliding blocks 200 is adjusted according to the width of the refrigeration components, and then the limiting screw 250 is rotated to make the limiting block 251 move downward, thereby causing the limiting groove 252 and the guide rod 240 to abut, fixing the sliding block 200; after suspending the refrigeration components on the hook 210, the bidirectional screw 220 is rotated by rotating the handle 221 to make the clamping plates 230 on both sides of the hook 210 move closer to each other, clamping the refrigeration components and preventing them from swaying on the hook 210.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
