Description

Technical Field

[0001] This utility model relates to beam-column structures, and in particular to a wire rope position adjustment mechanism for an electric hoist. Background Technology

[0002] Hydraulic engineering projects often involve numerous sluice gates, some of which require electric hoists for opening and closing. These hoists are connected to the gates via steel wire ropes. In some renovation projects, friction sometimes occurs between the steel wire rope and the hoisting hole when the rope passes through it, potentially leading to serious safety accidents. There are two main solutions to this problem: one is to replace the hoist with a specially designed one and reinstall the lifting rails; the other is to rebuild the entire foundation slab and alter the beam structure. Both solutions require extensive civil engineering work, resulting in massive projects. Furthermore, due to the varying widths of the hoisting holes, the spacing of the steel wire rope cannot be adjusted accordingly, limiting their applicability. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a wire rope position adjustment mechanism for an electric hoist, which solves the problem that when the wire rope passes through the lifting hole, there is sometimes friction between the wire rope and the lifting hole, which can lead to serious engineering safety accidents. At the same time, due to the different widths of the lifting holes, it is impossible to adjust the spacing of the wire rope according to the lifting hole, which limits its use.

[0004] To solve the above-mentioned technical problems, this utility model provides a wire rope position adjustment mechanism for an electric hoist, including a frame, a winding roller rotatably arranged inside the frame, a load-bearing wire rope wound on both sides of the winding roller, the load-bearing wire rope being connected to a movable pulley through a pulley mechanism, a hook being provided on one side of the movable pulley, the pulley mechanism being mounted on an adjustment mechanism, the pulley mechanism including a first I-beam steel frame and a second I-beam steel frame, a first mounting frame being provided on one side of the first I-beam steel frame, a first upper fixed pulley being provided inside the first mounting frame, a second mounting frame being provided on one side of the second I-beam steel frame, a second upper fixed pulley being rotatably arranged inside the second mounting frame, wherein the adjustment mechanism is mounted on the bottom beam of the gate chamber.

[0005] Preferably, a first auxiliary fixed pulley is arranged horizontally on one side of the first mounting frame, and a second auxiliary fixed pulley is arranged horizontally on one side of the second mounting frame. This can tension the load-bearing wire rope and reduce the spacing of the load-bearing wire rope, allowing the load-bearing wire rope to pass through the lifting hole.

[0006] Preferably, the load-bearing steel wire rope has a first upper fixed pulley, a second upper fixed pulley, a first auxiliary fixed pulley, and a second auxiliary fixed pulley on one side, and is connected to a movable pulley.

[0007] Preferably, the load-bearing steel wire rope is also connected to a top fixed pulley, which is mounted on the frame to enable stable winding and unwinding of the load-bearing steel wire rope.

[0008] Preferably, the adjusting mechanism includes a first crossbeam and a second crossbeam, which are mounted on the bottom beam of the gate chamber. A mounting groove is provided on one side of the first crossbeam, and a bidirectional ball screw is rotatably mounted in the mounting groove. A first screw nut and a second screw nut are provided on both sides of the bidirectional ball screw. The first screw nut is connected to a first I-shaped steel frame, and the second screw nut is connected to a second I-shaped steel frame. This allows for adjustment of the distance between the first and second I-shaped steel frames to accommodate different widths of lifting holes.

[0009] Preferably, one end of the bidirectional ball screw is connected to the drive shaft of the drive motor, and the drive motor is located on one side of the first crossbeam and can control the rotation direction of the bidirectional ball screw.

[0010] Preferably, a first guide block is provided on one side of the bottom of the first I-shaped steel frame, and a second guide block is provided on one side of the bottom of the second I-shaped steel frame. One end of the first guide block and the second guide block are slidably disposed in the guide groove, which is disposed on the second crossbeam, so as to guide the movement of the first I-shaped steel bar and the second I-shaped steel frame.

[0011] The beneficial effects of the utility model are:

[0012] 1. This application, by setting a first upper fixed pulley, a second upper fixed pulley, a first auxiliary fixed pulley, and a second auxiliary fixed pulley on both sides of the lifting hole, can shorten the spacing of the load-bearing wire rope, thereby allowing the load-bearing wire rope to pass through the lifting hole and preventing the load-bearing wire rope from rubbing against the lifting hole, thus ensuring high safety.

[0013] 2. This application can adjust the spacing between the first I-shaped steel bar and the second I-shaped steel frame according to different widths of lifting holes, thereby meeting the needs of lifting holes of different widths and having a wide range of applications.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All directional indicators (such as up, down, left, right, front, back, etc.) in the present utility model are only used to explain the relative positional relationship and movement of each component in a certain posture (as shown in the accompanying drawings). If the specific posture changes, the directional indicator will also change accordingly.

[0022] Please see Figures 1-4 A wire rope position adjustment mechanism for an electric hoist includes a frame 6, a take-up roller 8 rotatably mounted inside the frame 6, a load-bearing wire rope 9 wound on both sides of the take-up roller 8, the load-bearing wire rope 9 being connected to a movable pulley 10 via a pulley mechanism 1, a hook 11 being provided on one side of the movable pulley 10, a take-up motor 5 for rotating the take-up roller 8 being provided on one side of the frame 6, the pulley mechanism 1 being mounted on an adjustment mechanism 4, the pulley mechanism 1 including a first I-beam steel frame 103 and a second I-beam steel frame 104, a first mounting frame 102 being provided on one side of the first I-beam steel frame 103, a first upper fixed pulley 101 being provided inside the first mounting frame 102, a second mounting frame 105 being provided on one side of the second I-beam steel frame 104, a second upper fixed pulley 106 being rotatably mounted inside the second mounting frame 105, wherein the adjustment mechanism 4 is mounted on a gate chamber bottom beam 2.

[0023] A first auxiliary fixed pulley 107 is horizontally arranged on one side of the first mounting bracket 102, and a second auxiliary fixed pulley 108 is horizontally arranged on one side of the second mounting bracket 105. This can tension the load-bearing steel wire rope 9 and reduce the spacing of the load-bearing steel wire rope 9, allowing the load-bearing steel wire rope 9 to pass through the lifting hole 3. The first upper fixed pulley 101, the second upper fixed pulley 106, the first auxiliary fixed pulley 107, and the second auxiliary fixed pulley 108 on one side of the load-bearing steel wire rope 9 are connected to the movable pulley 10.

[0024] In use, the first I-beam steel frame 103 and the second I-beam steel frame 104 are erected on both sides of the gate chamber bottom beam 2. Then, the load-bearing steel wire ropes 9 pass through the first upper fixed pulley 101 and the first auxiliary fixed pulley 107 on both sides, pass through the second upper fixed pulley 106 and the second auxiliary fixed pulley 108, and then pass through the lifting hole 3 and connect to the movable pulley 10. When the winding motor 5 winds the winding roller 8, the distance between the load-bearing steel wire ropes 9 can be shortened through the transmission of the first upper fixed pulley 101, the second upper fixed pulley 106, the first auxiliary fixed pulley 107 and the second auxiliary fixed pulley 108, thereby lifting the heavy object through the hook 11.

[0025] Furthermore, the load-bearing steel wire rope 9 is also connected to the top fixed pulley 7, which is mounted on the frame 6, enabling the load-bearing steel wire rope 9 to be stably wound and unwound.

[0026] Please see Figure 5 and Figure 6 The adjusting mechanism 4 includes a first crossbeam 401 and a second crossbeam 402. The first crossbeam 401 and the second crossbeam 402 are mounted on the bottom beam 2 of the gate chamber. An installation groove 407 is provided on one side of the first crossbeam 401. A bidirectional ball screw 408 is rotatably installed in the installation groove 407. A first screw nut 405 and a second screw nut 409 are provided on both sides of the bidirectional ball screw 408. The first screw nut 405 is connected to the first I-shaped steel frame 103, and the second screw nut 409 is connected to the second I-shaped steel frame 104. The distance between the first I-shaped steel frame 103 and the second I-shaped steel frame 104 can be adjusted to meet the use of different width lifting holes 3. One end of the bidirectional ball screw 408 is connected to the drive shaft of the drive motor 403. The drive motor 403 is located on one side of the first crossbeam 401 and can control the rotation direction of the bidirectional ball screw 408.

[0027] After the first crossbeam 401 and the second crossbeam 402 are installed on the bottom beam 2 of the gate chamber, the distance between the first I-beam steel frame 103 and the second I-beam steel frame 104 can be adjusted by the width of the hoisting hole 3. The drive motor 403 drives the bidirectional ball screw 408 to rotate, and the first screw nut 405 and the second screw nut 409 move in opposite directions. The first screw nut 405 drives the first I-beam steel frame 103 to move, and the second screw nut 409 drives the second I-beam steel frame 104 to move, thereby adjusting the distance between the first I-beam steel frame 103 and the second I-beam steel frame 104, so as to meet the use of hoisting holes of different widths.

[0028] Furthermore, a first guide block 404 is provided on one side of the bottom of the first I-shaped steel frame 103, and a second guide block 410 is provided on one side of the bottom of the second I-shaped steel frame 104. One end of the first guide block 404 and the second guide block 410 are slidably disposed on the guide groove 406, which is disposed on the second crossbeam 402. The movement of the first I-shaped steel frame 103 causes the first guide block 404 to move within the guide groove 406, and the movement of the second I-shaped steel frame 104 causes the second guide block 410 to move within the guide groove 406, thereby guiding the movement of the first I-shaped steel frame 103 and the second I-shaped steel frame 104.

[0029] 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.
