Description

Technical Field

[0001] The utility model relates to the technical field of winches, and more particularly to a winch. Background Art

[0002] A winch is a light and small lifting device that winds a steel wire rope around a drum to lift or tow an object. The winch can rotate the reel to vertically lift, horizontally or obliquely tow heavy objects.

[0003] In coal mine production, winches are usually used for underground hoisting work. To ensure the normal operation of the winch, the winch needs to be installed on a platform at a certain height. In the prior art, the winch is generally installed on a platform with a certain height such as a scaffolding. However, as the working face changes, the winch may be applied between multiple different scaffolds. Due to different support structures of different scaffold platforms and different spacings between the support rods of the scaffolds, the base of the winch may not be able to be installed on the scaffold. Currently, a wooden board is usually temporarily processed according to the required size, and the winch is installed on the scaffold through the wooden board. However, the operation of temporarily processing the wooden board underground is relatively cumbersome, and such temporary supports are also unstable, affecting the safety of the hoisting work.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention and its application or use. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0029] As Figure 1 and Figure 2 shown, an embodiment of the present invention provides a winch, which includes a body, a bottom plate 100 and a driving assembly 200. Among them, the body is used for winding a cable, the body is arranged on the bottom plate 100, the bottom plate 100 has an installation cavity penetrating along the extending direction, two connecting plates 110 are symmetrically arranged in the installation cavity, the two connecting plates 110 are adjustable in distance along the extending direction, and the connecting plate 110 is provided with an installation hole 111, and the installation hole 111 is used for fixing the bottom plate 100. The driving assembly 200 is arranged on the bottom plate 100, and the driving assembly 200 is respectively drivingly connected to the two connecting plates 110, and is used to drive the two connecting plates 110 to approach or separate from each other, so as to adjust the distance between the installation holes 111 on the two connecting plates 110.

[0030] Applying the technical solution of the present invention, the bottom plate 100 of the winch can be fixed on the scaffolding through the installation holes 111 of the connecting plates 110 to hoist the underground construction equipment. In this application, the two connecting plates 110 are movably arranged in the installation cavity, and the driving assembly 200 is used to drive the two connecting plates 110 to move relatively away or close to each other, so as to be able to adjust the relative distance between the installation holes 111 on the two connecting plates 110, so that the bottom plate 100 can adapt to the scaffolding support structures with different distances. With such a setting, compared with the technical solution of temporarily processing wooden boards underground and fixing the winch on the wooden boards in the traditional technical solution, the position of the installation holes 111 on the bottom plate 100 can be adjusted at any time, simplifying the installation process and improving the installation efficiency of the equipment. Moreover, through the installation holes 111, the bottom plate 100 can be directly fixed on the scaffolding without placing it on the scaffolding through a wooden board or other support plates, and the connection with the scaffolding is more stable. When the winch hoists the equipment, the risk of the winch tipping or falling can be reduced, ensuring the personal safety of the personnel during underground construction.

[0031] Specifically, the installation hole 111 can be a threaded hole or other structures to facilitate threaded connection with the frame body or connecting piece of the scaffolding.

[0032] In a specific embodiment of the present application, the driving assembly 200 is disposed in the installation cavity. The driving assembly 200 includes a driving rod, two nuts 230, and a rotating motor 240. Among them, the driving rod includes a first thread section 210 and a second thread section 220 that are spaced apart along the extending direction. The thread directions of the first thread section 210 and the second thread section 220 are opposite. The two nuts 230 are arranged in one-to-one correspondence with the two connecting plates 110. The nut 230 is fixedly connected to the corresponding connecting plate 110. One of the nuts 230 is in threaded engagement with the first thread section 210, and the other nut 230 is in threaded engagement with the second thread section 220. The rotating motor 240 is drivingly connected to the driving rod to drive the driving rod to rotate. Through the above arrangement, the rotating motor 240 can drive the first thread section 210 and the second thread section 220 on the driving rod to rotate. When the first thread section 210 and the second thread section 220 rotate, since the connecting plate 110 is limited by the inner wall of the installation cavity in the installation cavity, the nut 230 fixedly connected to the connecting plate 110 cannot rotate. Due to the threaded engagement of the nut 230 with the first thread section 210 and the second thread section 220, the nut 230 will move linearly along the extending direction of the driving rod. Since the thread directions of the first thread section 210 and the second thread section 220 are opposite, when the driving rod rotates, the moving directions of the two nuts 230 are opposite, and the two nuts 230 can drive the two connecting plates 110 to move in opposite directions, realizing the adjustment of the distance between the mounting holes 111 on the two connecting plates 110. Moreover, through the above-structured arrangement, the distance between the mounting holes 111 on the two connecting plates 110 can be adjusted more conveniently. The two connecting plates 110 are connected by the driving rod, and the connecting plates 110 can also be fixed in the installation cavity, improving the structural stability of the parts in the installation cavity.

[0033] Optionally, the rotating motor 240 can be a motor with bidirectional output. The driving rod is separately provided. The first thread section 210 and the second thread section 220 are respectively arranged on two sections of the driving rod. The rotating motor 240 is arranged between the two ends of the driving rod to drive the first thread section 210 and the second thread section 220 to rotate simultaneously, realizing the synchronous movement of the two connecting plates 110.

[0034] Optionally, there can be two rotating motors 240, and they are motors with unidirectional output. One of the rotating motors 240 is drivingly connected to the first thread section 210, and the other rotating motor 240 is drivingly connected to the second thread section 220. In this way, one of the rotating motors 240 can be controlled separately to drive one of the connecting plates 110 to move, realizing the separate adjustment of the connecting plate 110. When one of the connecting plates 110 is fixed on the scaffold, the length of the other connecting plate 110 extending out of the installation cavity can be adjusted according to the actual installation position, without affecting the position of the main body in the horizontal direction while completing the installation.

[0035] In other embodiments of the present application, the driving assembly 200 may be other manually adjustable mechanisms fixed by limiting members, such as a structure using a clamping block and a sliding groove. A sliding groove is provided on the bottom plate 100, and a protruding adjusting block is provided on the connecting plate 110. The adjusting block is movably arranged in the sliding groove. The position of the connecting plate 110 is manually adjusted through the adjusting block, and the movement of the connecting plate 110 is restricted by restricting the adjusting block with a clamping block, so that the connecting plate 110 is relatively fixed in the installation cavity. Compared with the solution driven by the rotating motor 240 in the present application, such a setting can reduce the production cost of the winch.

[0036] Furthermore, a guiding assembly is also provided between the connecting plate 110 and the installation cavity to guide the movement of the connecting plate 110. Through the above setting, the guiding assembly can play a guiding role on the connecting plate 110, ensuring that the movement direction of the connecting plate 110 will not deviate, and improving the accuracy of the distance adjustment between the mounting holes 111 on the two connecting plates 110.

[0037] In a specific embodiment of the present application, the guiding assembly includes a slide rail 120 and a plurality of sliders 130. The slide rail 120 is arranged in the installation cavity and extends along the extending direction of the bottom plate 100. Each connecting plate 110 is fixedly connected with a slider 130, and the slider 130 is movably arranged on the slide rail 120. Through the above setting, the slider 130 can move along the slide rail 120 to guide the movement of the connecting plate 110.

[0038] Furthermore, there are two slide rails 120. The two slide rails 120 are arranged at intervals along the width direction of the bottom plate 100. Connecting rods 140 are arranged on both nuts 230. The two connecting rods 140 are arranged in one-to-one correspondence with the two connecting plates 110. The connecting rods 140 extend along the width direction of the bottom plate 100 and are fixedly connected with the corresponding connecting plates 110. Sliders 130 are arranged at both ends of each connecting rod 140. Due to the sliding friction between the slider 130 and the slide rail 120, through the above setting, sliders 130 are arranged at both ends of the connecting rod 140, which can improve the stability of the movement of the connecting plate 110 in the installation cavity, prevent the connecting plate 110 from being stuck due to the asynchronous movement on both sides of the connecting plate 110, and ensure the stability of the movement of the connecting plate 110.

[0039] Specifically referring to Figure 2 As shown, a support rod 160 is also provided between the connecting rod 140 and the connecting plate 110 to improve the structural stability of the connecting rod 140.

[0040] Specifically in this embodiment, a guiding groove may be provided on the slider 130, and the slide rail 120 is in guiding cooperation with the guiding groove. The slider 130 moves along the slide rail 120 through the guiding groove.

[0041] In other embodiments of the present application, an extension groove can be directly provided on the side wall of the installation cavity, and the slider 130 is movably arranged in the extension groove to guide the movement of the connecting plate 110. Further, the connecting plate 110 can also be integrally guided and cooperated with the extension groove to further improve the stability of the movement of the connecting plate 110.

[0042] As Figure 3 shown, the guiding assembly further includes a plurality of pulleys 150. A pulley 150 is fixedly arranged on the side wall of each connecting plate 110, and the pulley 150 is slidably engaged with the inner wall of the installation cavity to guide the movement of the connecting plate 110. Through the above arrangement, the plurality of pulleys 150 can reduce the sliding friction between the connecting plate 110 and the inner wall of the installation cavity by rolling, and further improve the stability of the movement of the connecting plate 110.

[0043] Further, in order to improve the space utilization rate, a receiving groove can be formed on the surface of the connecting plate 110 to receive the pulley 150.

[0044] Specifically, in the present application, two limiting blocks 250 are arranged in the installation cavity. The two limiting blocks 250 are arranged at intervals along the length direction of the bottom plate 100 and are both located between the two connecting plates 110 to limit the movement of the two connecting plates 110 approaching each other. Through the above arrangement, the two limiting blocks 250 can prevent the two connecting plates 110 from approaching too closely and prevent the installation hole 111 from entering the installation cavity, so as to ensure that the installation hole 111 is always located outside the installation cavity and ensure the normal use of the installation hole 111.

[0045] Further, the two limiting blocks 250 are correspondingly arranged, and both ends of the driving rod are rotatably connected to the two limiting blocks 250 respectively. The limiting block 250 can stop the movement of the nut 230 to limit the movement of the two connecting plates 110 moving away from each other. Through the above arrangement, the driving rod can be rotatably erected in the installation cavity through the two limiting blocks 250, and the two limiting blocks 250 can limit the displacement of the two connecting plates 110 moving away from each other while limiting the movement of the two connecting plates 110 approaching each other, making the space in the installation cavity more compact and making full use of the space in the bottom plate 100.

[0046] In other embodiments of the present application, the distance for limiting the movement of the two connecting plates 110 approaching each other can also be adjusted by arranging a plurality of limiting blocks 250.

[0047] Specifically, blind holes are provided on the end faces of the two limiting blocks 250 arranged oppositely. Both ends of the driving rod are respectively inserted into the two blind holes and can be cooperated with the inner walls of the blind holes through bearings to reduce the friction between the limiting block 250 and the driving rod.

[0048] Specifically, the main body includes a reel 300 for winding a cable. The winch further includes a pressing assembly 400 disposed on the base plate 100 and configured to abut against the surface of the cable wound on the reel 300 to press the cable. After the cable is wound around the reel 300 for a certain number of turns, the cable may become disordered. By providing the pressing assembly 400, the wound cable can be pressed by the pressing assembly 400 to prevent the cable from loosening, facilitating the movement of the winch between different scaffolds.

[0049] Specifically referring to Figure 4 As shown, the pressing assembly 400 includes an arc-shaped plate 410 and an elastic member 420. Among them, the arc-shaped plate 410 extends along the extension direction of the reel 300, and the concave surface of the arc-shaped plate 410 abuts against the surface of the cable; a plurality of elastic members 420 are provided, and the plurality of elastic members 420 are spaced apart along the extension direction of the arc-shaped plate 410. The elastic member 420 is configured to provide an elastic force in the direction towards the reel 300 for the arc-shaped plate 410. Through the above arrangement, the elastic member 420 provides an elastic force for the arc-shaped plate 410 to ensure that the arc-shaped plate can closely adhere to the surface of the cable.

[0050] Specifically, the elastic member 420 can be in the structure of a sleeve, with a spring disposed between the inner sleeve and the outer sleeve to provide an elastic force for the arc-shaped plate 410.

[0051] Furthermore, a plurality of arc-shaped plates 410 can also be provided, and the plurality of arc-shaped plates 410 are correspondingly arranged with the plurality of elastic members 420, so that the plurality of arc-shaped plates 410 press the cable according to the situation of the cable wound at different positions along the axial direction of the reel 300.
