Description

Technical Field

[0001] This utility model relates to the field of winch housings, and more specifically, to a lightweight housing structure for a small crane. Background Technology

[0002] Small cranes typically use winches as their power source, which drive the lifting rope to rotate and lift objects. Patent publication number CN219603116U discloses a vehicle-mounted small crane, relating to the field of road construction technology. It includes a base and a column, with the column fixedly connected to the top of the base. A connecting seat is rotatably connected to the outer side of the column's top, and a connecting frame is fixedly connected to the top of the connecting seat. A connecting shaft is fixedly installed inside the top of the connecting frame, and three first adjustment holes are provided on the top of the connecting frame. A telescopic boom is rotatably connected to the outer side of the connecting shaft. The telescopic boom consists of a main boom and an auxiliary boom, with the auxiliary boom located inside the main boom. Three second adjustment holes are provided on the surfaces of both the main boom and the auxiliary boom, and a third adjustment hole is provided at one end of the main boom. A first fixing pin is installed inside the first adjustment hole, and a second fixing pin is fixedly installed inside the second adjustment hole. This utility model is portable, easy to use, and significantly reduces safety hazards while saving labor costs.

[0003] In existing technologies, when the aforementioned winches are in use, both the wound wire and the winch itself are exposed to the outside without a casing to protect them. Especially when used outdoors, the wound area is a dangerous part, and the winch vibrates and generates significant noise during operation, reducing the quality of the working environment. Therefore, there is a need for a casing that can effectively isolate and protect the wound area and also eliminate the noise generated by the winch during operation. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a lightweight body shell structure for a small crane. It can enclose the exterior of the winch without affecting its heat dissipation, effectively reducing the noise generated and improving the quality of the working environment. Secondly, the isolation component can effectively protect and isolate the winding area, ensuring that the wire does not pose a threat to the outside world during the winding process. At the same time, it also protects the wire in the winding area from dust accumulation and other damage caused by pressure during the winding process, thus extending the service life of the device.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] (1) This solution can effectively isolate the winding area by using the isolation component, and the use of the wire groove can reduce the friction generated during the winding process and extend the service life of the wire. In addition, it can be locked with the noise reduction component to complete the fixation on both sides and improve the overall stability of the casing.

[0019] (2) This solution uses noise reduction components to wrap the winch, which can partially eliminate the noise generated during operation. It can also be connected to the fixed rod, making the isolation components and noise reduction components more reliable, improving the quality of the working environment and the overall practicality of the machine casing.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Example 1:

[0030] Please see Figure 1-4 A lightweight body shell structure for a small crane includes a mounting plate 1. A main boom 2 is fixedly mounted on the bottom end of the mounting plate 1. A pulley 3 is fixedly mounted on the top right end of the main boom 2. A wire body 4 is slidably mounted on the surface of the pulley 3. A partition 5 is fixedly mounted on the top end of the mounting plate 1. A winch 6 is fixedly mounted on the side of the partition 5. A rotating shaft 7 is fixedly sleeved on the output shaft of the winch 6. An isolation component 8 is slidably mounted inside the partition 5. A noise reduction component 9 is detachably mounted on the outside of the winch 6. The left end of the wire body 4 is wound and mounted on the surface of the rotating shaft 7.

[0031] It should be noted that the connection methods of the winch 6 and the line body 4, as well as the mounting plate 1 and the main boom 2 in this utility model are consistent with the connection methods of the same components in the prior art. The structure of the component connected at the end of the line body 4 is also the prior art in the prior art, so it will not be described in detail in this utility model.

[0032] The isolation assembly 8 includes an isolation housing 801, a fixing rod 802 fixedly installed inside the isolation housing 801, a wire groove 803 opened on the front of the isolation housing 801, rollers 804 rotatably installed at both the upper and lower ends of the wire groove 803, a baffle 805 rotatably installed on the front of the isolation housing 801 on one side of the rollers 804, a plastic clip 806 adhered to the baffle 805, and a groove opened inside the isolation housing 801, the size of the groove being adapted to the size of the plastic clip 806;

[0033] Specifically, the size of the groove is matched with the size of the plastic clip 806 to make the baffle 805 stand in a vertical position with a certain degree of stability. When the isolation housing 801 moves, it opens to allow the line to pass through. The surface of the roller 804 rotates with the surface of the line 4 to reduce friction between them and extend the service life of each component. Finally, the isolation housing 801 and the fixing rod 802 are used to strengthen the fixation between the partitions 5 and the safety of the rotation range of the rotating shaft 7.

[0034] The noise reduction component 9 includes a housing cover 901. A heat dissipation groove 902 is provided on one side of the housing cover 901. Sound-absorbing cotton 903 is fixedly adhered to the inner wall of the housing cover 901. A protruding plate 904 is fixedly installed on the outer wall of the housing cover 901. A threaded rod 905 is fixedly installed on the outer side of the outer end of the protruding plate 904. A hexagonal nut 906 is threadedly installed on the surface of the threaded rod 905. The housing cover 901 is wrapped around the outside of the winch 6 by the sound-absorbing cotton 903. The position of the threaded rod 905 corresponds to the position of the fixed rod 802. The hexagonal nut 906 can be threadedly connected to the end of the fixed rod 802.

[0035] Specifically, by rotating a portion of the hexagonal nut 906 to connect it to the fixed rod 802, and by threading the other portion to the threaded rod 905, a fixed connection is achieved between the housing 901 and the isolation housing 801, ensuring overall stability. Secondly, the sound-absorbing cotton 903 is arranged around the hoist to partially absorb the noise generated by the hoist 6 during operation, improving the quality of the working environment.

[0036] The working principle of this utility model is as follows: After the wire is wound around the surface of the rotating shaft 7, the isolation housing 801 is moved so that the fixing rod 802 passes through the round hole on the surface of the partition plate 5. The wire then passes through the baffle 805 and enters the inside of the wire groove 803. Then the baffle 805 is closed, so that the plastic clip 806 enters the groove and is fixed. At this time, the outer end of the fixing rod 802 is in contact with the threaded rod 905. Then the hexagonal nut 906 is rotated so that the end of the hexagonal nut 906 near the fixing rod 802 is gradually threaded onto the surface of the fixing rod 802 to complete the fixation. The heat dissipation groove 902 is used to dissipate heat and prevent the winch 6 from being overloaded. The sound-absorbing cotton 903 locally absorbs the noise generated by the winch 6.

[0037] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
