Description

Technical Field

[0001] This utility model relates to the field of ship hoisting technology, specifically to a small ship repair hoisting auxiliary device. Background Technology

[0002] On grease and ball bearing tracks, small vessels are usually towed directly onto the slipway using winches to facilitate repair or maintenance. However, due to the limited height of the winch and the long towing path, it is difficult to tow small vessels taller than the winch to the slipway. Therefore, some people have designed an auxiliary device, such as the Chinese utility model patent with announcement number CN115432613B, which specifically discloses a hoisting auxiliary device for small vessel repair.

[0003] However, in actual use, it has been found that when the hoisting auxiliary equipment used for small ship repairs is working on the rotating roller, the rope can easily slide left and right on the roller. Once the rope slides, the ship is likely to sway, which greatly increases the safety hazard. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hoisting auxiliary device for small ship repair, comprising a moving component, a lifting component, and a sliding roller component, wherein the lifting component is disposed above the moving component, and the sliding roller component is disposed above the lifting component.

[0006] The sliding roller assembly includes a U-shaped frame, a rotating roller, a bidirectional lead screw, a lead screw slider, and a limiting plate. The rotating roller is rotatably connected to the inner side of the U-shaped frame via a sliding bearing, and a groove is formed on the inner side of the U-shaped frame. The bidirectional lead screw is rotatably connected to the inner side of the groove, and a lead screw slider is symmetrically threaded onto the bidirectional lead screw. A limiting plate is fixed on the lead screw slider, and the limiting plate is sleeved on the outer side of the rotating roller. By setting the limiting plate on the outer side of the rotating roller, the left and right sliding range of the pull rope can be adjusted by adjusting the distance between the limiting plates.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a hoisting auxiliary device for small ship repair, including a moving component 1, a lifting component 2 and a sliding roller component 3, wherein the lifting component 2 is disposed above the moving component 1 and the sliding roller component 3 is disposed above the lifting component 2.

[0023] The sliding roller assembly 3 includes a U-shaped frame 301, a rotating roller 302, a bidirectional lead screw 303, a lead screw slider 304, and a limiting plate 305. The rotating roller 302 is rotatably connected to the inner side of the U-shaped frame 301 via a sliding bearing, and a groove 3011 is provided on the inner side of the U-shaped frame 301. The bidirectional lead screw 303 is rotatably connected to the inner side of the groove 3011, and the lead screw slider 304 is symmetrically threaded onto the bidirectional lead screw 303. The limiting plate 305 is fixed on the lead screw slider 304 and is sleeved on the outer side of the rotating roller 302. By setting the limiting plate 305 on the outer side of the rotating roller 302, the left and right sliding range of the pull rope can be adjusted by adjusting the distance between the limiting plates 305.

[0024] Furthermore, the movable component 1 includes a base plate 101, casters 102, support feet 103, and push rod 104. The casters 102 and support feet 103 are both located below the base plate 101, and two casters 102 and two support feet 103 are symmetrically arranged. The push rod 104 is fixed to the side of the base plate 101. The casters 102 facilitate the movement of the device, the support feet 103 provide support, and the push rod 104 facilitates lifting the support feet 103 to push the device.

[0025] Furthermore, the support foot 103 is provided with fixing holes, which can be used with bolts to fix the device to the ground.

[0026] Furthermore, the lifting assembly 2 includes a hydraulic cylinder 201, which is fixed on the base plate 101. A reinforcing rib 202 is fixed on the side of the hydraulic cylinder 201. A U-shaped frame 301 is fixed at the output end of the hydraulic cylinder 201. The hydraulic cylinder 201 is used to adjust the height of the sliding roller assembly 3, and the reinforcing rib 202 is used to improve the stability of the hydraulic cylinder 201.

[0027] Furthermore, one end of the bidirectional lead screw 303 passes through the U-shaped frame 301 and is connected to a knob 3031. The knob 3031 is mainly for facilitating the rotation of the bidirectional lead screw 303.

[0028] Furthermore, the lead screw slider 304 is fitted against the inner wall of the slide groove 3011, and the lead screw slider 304 and the slide groove 3011 are slidably connected, thereby restricting the lead screw slider 304.

[0029] In summary, when using this device, simply move it to a specific position using the casters 102, then secure it using the support feet 103. The hoisting rope is then passed over the rotating roller 302 for normal use. Before use, the knob 3031 can be rotated to drive the bidirectional lead screw 303, which in turn drives the two lead screw sliders 304 to move closer or further apart. This, in turn, moves the limiting plates 305, adjusting the distance between the two limiting plates 305 to adjust the left and right sliding range of the rope, thus improving its stability during use. The hydraulic cylinder 201 can also be activated to adjust the height of the roller assembly 3.

[0030] It is worth noting that the entire device is controlled by a central control console. Since electrical control equipment is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
