Description

Technical Field

[0001] This utility model relates to the technical field of hoists, and in particular to a guiding device for a hoist. Background Technology

[0002] The guiding device of a cargo hoist is a device used to keep cargo moving vertically. It typically consists of guide wheels, guide plates, or guide grooves to ensure that cargo moves along a prescribed track during the hoisting process.

[0003] In the actual operation of cargo hoists, the guide wheels of the guiding device often face a common and troublesome problem—wear. Over time, the guide wheels wear down due to friction with the track. When the guide wheels wear down, their shape and size may change, reducing the contact area with the track. When the guide wheels wear down to a certain extent, they will no longer be able to provide sufficient and stable contact force to reliably guide the cargo. This makes it highly likely that the cargo will deviate from the intended track during the hoisting process, which will not only damage the cargo itself but may also cause a series of safety hazards.

[0004] Furthermore, existing cargo hoist guiding devices have significant safety design flaws, and in most cases, they lack comprehensive safety protection mechanisms. If a traction component breaks unexpectedly during operation, the lack of effective braking and protection measures will cause the cargo to plummet rapidly under gravity, and the entire hoist system will instantly lose control, easily leading to serious safety accidents and causing irreparable personal injury and property damage. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, the purpose of this utility model is to propose a guiding device for a hoist that can effectively ensure a continuous and stable guiding force for the goods, significantly reduce the risk of the goods deviating from the track, and greatly improve the stability and safety of the goods transportation; at the same time, it can respond quickly in case of emergencies such as the breakage of the traction component, brake in time and protect, effectively avoid the goods falling and the system losing control, effectively protect the lives of personnel and reduce property losses.

[0007] To achieve the above objectives, this utility model proposes a guiding device for a hoist, comprising a U-shaped slide rail, a U-shaped sliding plate, two sets of directional mechanisms, two limiting mechanisms, a transmission mechanism, and a drive assembly.

The two sets of directional mechanisms are slidably mounted on the U-shaped sliding plate, and are movably connected to the two sides of the U-shaped slide rail, wherein the two sets of directional mechanisms are staggered. The two limiting mechanisms are respectively mounted on the two side walls of the U-shaped sliding plate, and are respectively abutting against the corresponding limiting grooves. The transmission mechanism is rotatably mounted on the U-shaped sliding plate, and is respectively connected to the two limiting mechanisms. The drive assembly is mounted on the side wall of the U-shaped sliding plate, and is connected to one of the limiting mechanisms.

[0020] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] The guiding device of the hoist according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0022] like Figures 1-3 As shown, the guiding device of the hoist in this embodiment of the present invention may include a U-shaped slide rail 10, a U-shaped slide plate 20, two sets of orientation mechanisms 30, two limiting mechanisms 40, a transmission mechanism 50 and a drive assembly 60.

[0023] The U-shaped slide plate 20 is slidably mounted on the U-shaped slide rail 10, and multiple longitudinally arranged limiting grooves 11 are respectively provided on the two side walls of the U-shaped slide rail 10.

[0024] Two sets of orientation mechanisms 30 are slidably mounted on the U-shaped slide plate 20, and the two sets of orientation mechanisms 30 are movably connected to the two sides 12 of the U-shaped slide rail 10, wherein the two sets of orientation mechanisms 30 are staggered. Each set of orientation mechanisms 30 includes at least two equidistant side-by-side positioning mechanisms 30.

[0025] It is understandable that by distributing the two sets of orientation mechanisms 30 in a staggered manner, the guiding performance and stability can be effectively improved. When one orientation mechanism 30 fails, it will not affect the operation of the other orientation mechanisms 30 or the overall guiding stability.

[0026] Two limiting mechanisms 40 are respectively installed on the two side walls of the U-shaped slide plate 20, and the two limiting mechanisms 40 are respectively connected to the corresponding limiting grooves 11. The two limiting mechanisms 40 are used to limit the U-shaped slide plate 20, aiming to respond quickly and brake in time in case of emergencies such as breakage of the traction component, so as to prevent the U-shaped slide plate 20 from slipping and causing the goods to fall.

[0027] The transmission mechanism 50 is rotatably mounted on the U-shaped slide plate 20 and is connected to two limiting mechanisms 40 respectively. The drive assembly 60 is mounted on the side wall of the U-shaped slide plate 20 and is connected to one of the limiting mechanisms 40. The drive assembly is used to drive the transmission mechanism 50 to move the two limiting mechanisms 40 away from the limiting groove 1, thereby releasing the limiting effect on the U-shaped slide plate 20.

[0028] To clearly illustrate the previous embodiment, in one embodiment of this utility model, as follows: Figure 1As shown, the orientation mechanism 30 may include a slider 31, a telescopic rod 32, a spring 33, and a guide wheel 34.

[0029] The U-shaped slide plate 20 has multiple longitudinally arranged grooves 21, and the slider 31 is slidably disposed in the corresponding groove 21.

[0030] The telescopic rod 32 is horizontally set in the slide groove 21, and one end of the telescopic rod 32 is fixedly connected to the slider 31, while the other end of the telescopic rod 32 is fixedly connected to the end wall of the slide groove 21.

[0031] Spring 33 is sleeved on telescopic rod 32, with one end of spring 33 fixedly connected to the end wall of slide groove 21 and the other end of spring 33 fixedly connected to slider 31. Guide wheel 34 is rotatably mounted on slider 31 and is rollingly connected to the edge 12 of U-shaped slide rail 10.

[0032] Understandably, when the guide wheel 34 wears down, the tension of the spring 33 can push the slider 31 to move the guide wheel 34 toward the edge 12 of the U-shaped slide rail 10, ensuring that the guide wheel 34 always remains in contact with the edge 12 of the U-shaped slide rail 10. This effectively ensures a continuous and stable guiding force for the goods, significantly reducing the risk of goods deviating from the track and greatly improving the stability and safety of cargo transportation.

[0033] In one embodiment of this utility model, such as Figures 1-3 As shown, the limiting mechanism 40 may include a bracket 41, a support shaft 42, a drive bevel gear 43, a pawl 44, and a spring plate 45.

[0034] The bracket 41 is fixedly mounted on the side wall of the U-shaped slide plate 20, and the support shaft 42 is rotatably mounted on the bracket 41. One end of the support shaft 42 is connected to the active bevel gear 43, and the other end of the support shaft 42 is connected to the pawl 44. The pawl 44 is in contact with the corresponding limiting groove 11.

[0035] One end of the spring plate 45 is fixedly connected to the bracket 41, and the other end of the spring plate 45 abuts against the pawl 44.

[0036] To clearly illustrate the previous embodiment, in one embodiment of this utility model, as follows: Figure 1 As shown, the transmission mechanism 50 may include a transmission shaft 51 and two driven bevel gears 52, wherein the transmission shaft 51 is rotatably mounted on the U-shaped slide plate 20.

[0037] Two driven bevel gears 52 are respectively disposed at both ends of the transmission shaft 51, and the two driven bevel gears 52 mesh with the corresponding driving bevel gears 43 respectively.

[0038] Furthermore, in one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the drive assembly 60 may include a gear 61, a telescopic mechanism 62, and a rack 63.

[0039] The gear 61 is sleeved and fixed on the support shaft 42, and the telescopic mechanism 62 is set on the U-shaped slide plate 20. The output end of the telescopic mechanism 62 is fixedly connected to one end of the rack 63. When the output end of the telescopic mechanism 62 extends, the rack 63 meshes with the gear 61 and drives the gear 61 to rotate.

[0040] It should be noted that the telescopic mechanism 62 described in this embodiment can be an electric telescopic rod, a pneumatic cylinder, or a hydraulic cylinder.

[0041] Specifically, when the traction component breaks, the pawl 44, under the tension of the spring plate 45, abuts against the limiting groove 11 and limits the sliding U-shaped slide plate 20 to prevent the goods from falling. When it is necessary to release the limit on the U-shaped slide plate 20, the operator can control the output end of the telescopic mechanism 62 to extend and push the rack 63 towards the gear 61 until the rack 63 drives the gear 61 to rotate.

[0042] When gear 61 rotates, the rotating gear 61 drives pawl 44 to rotate and disengage from limiting groove 11 via support shaft 42. At the same time, the rotating support shaft 42 drives driven bevel gear 52 to rotate via driving bevel gear 43. Driven bevel gear 52 drives another driven bevel gear 52 to rotate synchronously via transmission shaft 51. The other driven bevel gear 52 drives another pawl 44 to rotate synchronously and disengage from the corresponding limiting groove 11, thereby releasing the limitation on U-shaped slide plate 20.

[0043] In summary, the guiding device of the hoist in this embodiment of the utility model can effectively ensure a continuous and stable guiding force for the goods, significantly reduce the risk of the goods deviating from the track, and greatly improve the stability and safety of the goods transportation; at the same time, it can respond quickly in the event of emergencies such as the breakage of the traction component, brake in time and protect, effectively avoid the goods falling and the system losing control, effectively protect the lives of personnel and reduce property losses.
