Modular pulley assembly

Abstract

This utility model provides a modular trolley assembly, relating to the field of cargo lifting technology. It includes a trolley body; a lifting rope, which is disposed on the surface of the trolley body to transmit and bear loads; a hook, disposed inside the trolley body for hooking cargo; and a protective device, detachably installed on the outside of the trolley body for protection. When the protective device is needed to protect the trolley body, it is fitted onto the connecting rod through the limiting hole and wraps around the trolley body. Then, washers and nuts are screwed onto the connecting rod in sequence, and finally, the first protective plate and the connecting plate are fixed with screws to complete the assembly. This utility model solves the problem that when using a trolley for lifting, the swinging of cargo can cause the trolley to collide with other objects, or the trolley to collide with other equipment or walls during movement, resulting in localized dents and corner deformation of the frame, especially at unprotected corners. Over time, this affects the service life of the trolley and hinders cargo lifting.

Description

Technical Field

[0001] This utility model relates to the field of cargo lifting technology, specifically to a modular trolley assembly. Background Technology

[0002] Cargo lifting pulleys are core equipment used to lift or move goods in industrial lifting and logistics handling scenarios. They work in conjunction with pulley blocks and ropes (chains, wire ropes) to save effort by leveraging the principle of leverage, while simultaneously achieving vertical lifting or horizontal movement of goods.

[0003] When using a trolley for lifting, the swinging of the cargo can cause the trolley to collide with other objects, or with other equipment or walls during movement. This can result in localized dents and corner deformations of the frame, especially at unprotected corners. Over time, this can affect the lifespan of the trolley and hinder cargo lifting. Utility Model Content

[0004] This invention provides a modular trolley assembly that solves the problems mentioned in the background section.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] An embodiment of this utility model provides a modular trolley assembly, comprising:

[0007] Main body of the trolley;

[0008] The suspension rope is set on the surface of the trolley body and serves to transmit and bear the load.

[0009] A hook, which is installed inside the trolley body, is used to hook and hang goods;

[0010] A protective device is provided, which is detachably installed on the outside of the trolley body to protect the trolley body.

[0011] With the above technical solution, when it is necessary to use a trolley for lifting goods, the protective device can be easily installed on the trolley by tightening the nuts and screws. The rubber pad can effectively reduce the impact force of other objects on the trolley, thus protecting the trolley from impacts by other objects during lifting or movement.

[0012] Furthermore, the protective device includes two limiting components, each of which includes two connecting rods. The two connecting rods are fixedly connected to the surface of the trolley body, and baffles are fixedly connected to the surface of the two connecting rods. Washers are threadedly connected to the surface of the two connecting rods, and nuts are threadedly connected to the surface of the two connecting rods.

[0013] Through the above technical solution, the setting of the limiting component can fix the position of the protective device, thereby protecting the main body of the trolley in all directions.

[0014] Furthermore, the protective device includes an outer frame assembly, the outer frame assembly includes a first protective plate, a connecting plate is detachably mounted on the surface of the first protective plate, and a second protective plate is fixedly connected to the surface of the connecting plate.

[0015] The above technical solution allows for the complete enclosure of the trolley body by setting up an outer frame component, protecting the trolley body from impacts by external objects.

[0016] Furthermore, the surfaces of the first and second protective plates are provided with limiting holes, the inner walls of the limiting holes are slidably connected to the surface of the connecting rod, and the size of the limiting holes is adapted to the circumferential surface of the connecting rod.

[0017] The above technical solution involves a connecting rod that is slidably connected to the limiting hole, allowing the entire protective device to slide up and down. After the hook catches the goods, the protective device is released, and it slides down under the influence of gravity, thus blocking the hook and preventing it from accidentally snagging on other objects when the goods are being lifted or moved.

[0018] Furthermore, an anti-collision component is fixedly connected to the surface of the outer frame assembly. The anti-collision component includes a mushroom cap, which is fixedly connected to the surface of the outer frame assembly. A rubber pad is detachably installed on the surface of the mushroom cap, and a square indentation is provided on the surface of the rubber pad. The size of the square indentation is adapted to the surface of the mushroom cap.

[0019] Through the above technical solution, the rubber pad can effectively reduce the impact force of external objects. By setting a square indentation, the mushroom cap can be embedded in the rubber pad, and it is also convenient to replace the rubber pad.

[0020] Furthermore, screws are threaded onto the surface of the first protective plate.

[0021] Through the above technical solution, screws can make the outer frame components more tightly connected.

[0022] Furthermore, a support rod is rotatably connected to the inner wall of the outer frame assembly, and a roller is fixedly connected to the surface of the support rod (417).

[0023] Through the above technical solution, the setting of the roller can effectively prevent the suspension rope from rubbing against the protective device during operation, thus preventing the suspension rope from being damaged or broken, thereby ensuring the normal operation of the trolley.

[0024] The above-described solution of this utility model has at least the following beneficial effects:

[0025] This invention allows for the convenient installation of a protective device on a trolley when it is needed for lifting goods. The device can be easily installed by tightening nuts and screws. The rubber pad effectively reduces the impact force of other objects on the trolley, protecting it from impacts during lifting or movement. The roller effectively prevents friction between the lifting rope and the protective device, thus preventing damage and breakage of the rope. This design protects the trolley without affecting its normal operation.

[0026] In this invention, when goods need to be hung with a hook, the protective device is slid upwards. The protective device will slide on the connecting rod through the limiting hole, thereby exposing the hook. After the goods are hooked, the protective device is released, and the protective device will slide down under the action of gravity, thereby blocking the hook and preventing the hook from accidentally getting caught on other objects when the goods are lifted or moved.

[0036] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0037] like Figures 1 to 5 As shown, an embodiment of the present invention provides a modular trolley assembly, including: a trolley body 1; a suspension rope 2 disposed on the surface of the trolley body 1; a hook 3 disposed inside the trolley body 1; and a protective device 4 detachably installed on the outside of the trolley body 1. The protective device 4 includes two limiting components 409, each including two connecting rods 410. The two connecting rods 410 are fixedly connected to the surface of the trolley body 1. A baffle 411 is fixedly connected to the surface of the two connecting rods 410. A washer 412 is threadedly connected to the surface of the two connecting rods 410. A nut 413 is threadedly connected to the surface of the two connecting rods 410. The protective device 4 includes an outer frame assembly 401, which includes a first protective plate 402. A connecting plate 403 is detachably mounted on the surface of the first protective plate 402. A second protective plate 404 is fixedly connected to the surface of the connecting plate 403. Limiting holes 414 are formed on the surfaces of the first protective plate 402 and the second protective plate 404. The inner wall of the limiting hole 414 is slidably connected to the surface of the connecting rod 410. The size of the limiting hole 414 is adapted to the circumferential surface of the connecting rod 410. A screw 415 is threadedly connected to the surface of the first protective plate 402.

[0038] In this embodiment of the utility model, when the protective device 4 is required to protect the trolley body 1, the protective device 4 is fitted onto the connecting rod 410 through the limiting hole 414 and wraps around the trolley body 1. Then, the gasket 412 and nut 413 are screwed onto the connecting rod 410 in sequence. Finally, the first protective plate 402 and the connecting plate 403 are fixed with screws 415 to complete the assembly. When the hook 3 is needed to hang goods, the protective device 4 is slid upward. The protective device 4 will slide on the connecting rod 410 through the limiting hole 414, thereby exposing the hook 3. After the goods are hooked, the protective device 4 is released. The protective device 4 will slide down under the action of gravity, thereby blocking the hook 3 and preventing the hook 3 from accidentally getting caught on other objects when the goods are lifted or moved.

[0039] like Figure 4 and Figure 6 As shown, a support rod 417 is rotatably connected to the inner wall of the outer frame assembly 401, and a roller 416 is fixedly connected to the surface of the support rod 417.

[0040] In this embodiment of the utility model, by setting up a roller 416, when the hoisting rope 2 is running, it will occasionally touch the protective device 4. The surface of the roller 416 is supported by a support rod 417, which can rotate on the surface of the outer frame assembly 401 through a bearing. This can effectively prevent the hoisting rope 2 from rubbing against the protective device 4 and causing damage or breakage of the hoisting rope, thereby ensuring the normal operation of the trolley.

[0041] like Figure 4 and Figure 7 As shown, an anti-collision component 405 is fixedly connected to the surface of the outer frame component 401. The anti-collision component 405 includes a mushroom cap 406. The mushroom cap 406 is fixedly connected to the surface of the outer frame component 401. A rubber pad 408 is detachably installed on the surface of the mushroom cap 406. A square indentation 407 is provided on the surface of the rubber pad 408. The size of the square indentation 407 is adapted to the surface of the mushroom cap 406.

[0042] In this embodiment of the utility model, by setting up the anti-collision component 405, when the rubber pad 408 of the anti-collision component 405 needs to be replaced after long-term use or damage, the staff only needs to remove the rubber pad 408 from the mushroom cap 406, and then insert the mushroom cap 406 into the rubber pad 408 through the square indentation 407 to complete the replacement.

[0043] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
