Description

Technical Field

[0001] This utility model belongs to the field of elevator technology, and in particular relates to a novel speed limiter rope clamping device for elevators. Background Technology

[0002] In modern architecture, elevators have become an indispensable vertical transportation tool. With their high efficiency and convenience, they greatly meet people's needs for rapid movement in high-rise buildings and are widely used in various building scenarios such as residential, commercial, and office buildings. As a key component of the elevator safety system, the rope clamp can quickly activate when the elevator speed exceeds a set threshold, tightly clamping the elevator wire rope with its clamping plate to effectively prevent further speeding and serious safety accidents. However, most rope clamps on the market are difficult to disassemble during actual use, making the clamping plate prone to wear after long-term use due to frequent friction with the wire rope. This not only affects the clamping effect and reduces its ability to limit elevator speed, but may also lead to the failure of the rope clamp due to excessive wear of the clamping plate, greatly increasing the safety hazards of elevator operation and threatening the lives of passengers. Therefore, we propose a new type of speed limiter rope clamping device for elevators. Utility Model Content

[0003] The purpose of this utility model is to provide a novel rope clamping device for elevator speed governors. It features a disassembly mechanism. Specifically, when the rope clamping plate needs replacement, loosening the bolts causes the spring to contract, moving the connecting piece and the positioning pin, disengaging the positioning pin from the I-shaped block, thus easily removing the rope clamping plate. During installation, the I-shaped block is inserted, the fixing plate is pressed to insert the positioning pin into its limit position, and then bolts are used to secure it. This facilitates the disassembly and installation of the rope clamping plate, making maintenance and replacement easier. It also prevents wear and aging issues from affecting the clamping effect on the elevator rope during long-term use, thus solving the problem of difficulty in disassembling the rope clamping plate in most rope clamps currently on the market.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a novel rope clamping device for elevator speed governors, comprising a drive box and two movable plates. The drive box is equipped with a disassembly mechanism and a rope clamping mechanism.

[0006] The disassembly mechanism includes rope clamping plates fixedly connected to one side of two moving plates that are close to each other. I-shaped blocks are fixedly connected to the opposite sides of the two rope clamping plates. Mounting plates are fixedly connected to the opposite sides of the two moving plates. I-shaped grooves are formed on the opposite sides of the two moving plates. The opposite sides of the two I-shaped grooves extend into the interior of the corresponding mounting plates. The opposite sides of the two I-shaped blocks extend into the interior of the corresponding I-shaped grooves and are slidably connected to the corresponding I-shaped grooves. The rope clamping mechanism includes a motor fixedly connected to the top of the drive box.

[0007] Furthermore, both of the two mounting plates have sliding grooves on their left and right sides, and the inner walls of several sliding grooves are slidably connected with positioning pins. One end of several positioning pins extends into the interior of the corresponding I-shaped block and is slidably connected to the corresponding I-shaped block, while the other end of several positioning pins extends to the exterior of the corresponding mounting plate.

[0008] Furthermore, each of the locating pins has a connecting piece fixedly connected to its outer wall, and a spring is wound around the outer wall of each of the locating pins. One end of each of the springs is fixedly connected to the corresponding connecting piece, and the other end of each of the springs is fixedly connected to the inner wall of the corresponding slide groove.

[0009] Furthermore, each of the locating pins has a fixing plate fixedly connected to one end away from the corresponding I-shaped block, and each of the fixing plates has two bolts threadedly connected to the corresponding mounting plate.

[0010] Furthermore, the output shaft of the motor is fixedly connected to a worm gear via a coupling, and the bottom end of the worm gear passes through the drive housing and is rotatably connected to the drive housing.

[0011] Furthermore, two rotating shafts are rotatably connected to the left inner wall of the drive box, and worm gears are fixedly connected to the outer walls of the two rotating shafts. The two worm gears mesh with worms. A guide rod is fixedly connected to the inner wall of the drive box, and two movable plates are slidably connected to the outer wall of the guide rod.

[0012] Furthermore, rhomboid blocks are fixedly connected to the outer walls of both rotating shafts, and connecting plates are hinged between the two rhomboid blocks and the two movable plates. Several guide grooves are provided on the left side of the drive box, and the left sides of the two movable plates extend to the outside of the drive box and are slidably connected to the corresponding guide grooves.

[0013] Furthermore, a frame is fixedly connected to the left side of the drive box, and several guide rods are fixedly connected to the frame. Several sliders are fixedly connected to the left side of each of the two movable plates, and the sliders are slidably connected to the corresponding guide rods.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a disassembly mechanism, when it is necessary to replace the rope clamping plate, after loosening the bolts, the spring contracts and drives the connecting piece and the positioning pin to move, so that the positioning pin disengages from the I-shaped block, and the rope clamping plate can be easily removed; during installation, insert the I-shaped block, press the fixing plate to make the positioning pin insert into the limit position, and then fix it with bolts. This facilitates the disassembly and installation of the rope clamping plate, makes maintenance and replacement easier, and avoids the problems of wear and aging that occur during long-term use, which affect the clamping effect on the elevator rope.

[0016] 2. By setting up a rope clamping mechanism, specifically, when the elevator overspeeds, the motor drives the worm gear to rotate, meshing with the worm wheel to rotate the shaft. The diamond-shaped block drives the sliding plate two through the connecting plate, which in turn causes the sliding plate one to drive the rope clamping plate to clamp the wire rope. When the speed is normal, the motor reverses and releases the clamp. Utilizing the self-locking performance of the worm gear and worm wheel, when the motor stops driving, the worm gear and worm wheel can remain relatively stationary, keeping the rope clamping plate in a clamped state. This prevents the rope clamping mechanism from loosening due to unexpected factors (such as motor failure, power outage, etc.), further improving the safety and reliability of elevator operation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6As shown, this utility model is a novel rope clamping device for an elevator speed governor, including a drive box 1 and two movable plates 21. The drive box 1 is equipped with a disassembly mechanism 2 and a rope clamping mechanism 3. The disassembly mechanism 2 includes rope clamping plates 22 respectively fixedly connected to the sides of the two movable plates 21 that are close to each other. I-shaped blocks 23 are fixedly connected to the sides of the two rope clamping plates 22 that are far apart from each other. Mounting plates 25 are fixedly connected to the sides of the two movable plates 21 that are far apart from each other. I-shaped grooves 24 are formed on the sides of the two movable plates 21 that are close to each other. The two I-shaped grooves 24 are far apart from each other. The two I-shaped blocks 23 extend into the interior of the corresponding mounting plate 25 on the side away from each other. The two I-shaped blocks 23 also extend into the interior of the corresponding I-shaped groove 24 and slide in connection with the corresponding I-shaped groove 24. The rope clamping mechanism 3 includes a motor 31 fixedly connected to the top of the drive box 1. Slide grooves 26 are provided on the left and right sides of both mounting plates 25. Positioning pins 27 are slidably connected to the inner walls of several slide grooves 26. One end of each positioning pin 27 extends into the interior of the corresponding I-shaped block 23 and slides in connection with the corresponding I-shaped block 23. The other end of each positioning pin 27 extends into the interior of the corresponding I-shaped block 23. On the exterior of the mounting plate 25, connecting pieces 28 are fixedly connected to the outer walls of several positioning pins 27, and springs 29 are wound around the outer walls of several positioning pins 27. One end of several springs 29 is fixedly connected to the corresponding connecting piece 28, and the other end of several springs 29 is fixedly connected to the inner wall of the corresponding slide groove 26. A fixing plate 210 is fixedly connected to the end of several positioning pins 27 away from the corresponding I-shaped block 23. Two bolts 211 are threadedly connected between several fixing plates 210 and the corresponding mounting plate 25. A disassembly mechanism 2 is provided. Specifically, when the rope clamping plate 22 needs to be replaced, after loosening the bolt 211, the spring 29 contracts and drives the connecting piece 28 and the positioning pin 27 to move, so that the positioning pin 27 disengages from the I-shaped block 23, and the rope clamping plate 22 can be easily removed. During installation, the I-shaped block 23 is inserted, the fixing plate 210 is pressed to make the positioning pin 27 insert into the limit position, and then the bolt 211 is used to fix it. This facilitates the disassembly and installation of the rope clamping plate 22, makes it easy to maintain and replace, and avoids the problems of wear and aging that occur during long-term use of the rope clamping plate 22, which affect the clamping effect on the elevator rope.

[0029] The output shaft of motor 31 is fixedly connected to worm gear 32 via a coupling. The bottom end of worm gear 32 passes through drive housing 1 and is rotatably connected to drive housing 1. Two rotating shafts 33 are rotatably connected to the inner wall of the left side of drive housing 1. Worm wheels 34 are fixedly connected to the outer walls of both rotating shafts 33, and both worm wheels 34 mesh with worm gear 32. A guide rod 35 is fixedly connected to the inner wall of drive housing 1. Two movable plates 36 are slidably connected to the outer walls of guide rod 35. Rhomboid blocks 37 are fixedly connected to the outer walls of both rotating shafts 33. Connecting plates 38 are hinged between the two rhomboid blocks 37 and the two movable plates 36. Several guide grooves 39 are provided on the left side of drive housing 1. The left side of the second movable plate 36 extends to the outside of the drive box 1 and is slidably connected to the corresponding guide groove 39. The left side of the drive box 1 is fixedly connected to a frame 312, and several guide rods 310 are fixedly connected to the frame 312. Several sliders 311 are fixedly connected to the left side of the two movable plates 21, and the sliders 311 are slidably connected to the corresponding guide rods 310. By setting the rope clamping mechanism 3, specifically when the elevator overspeeds, the motor 31 drives the worm gear 32 to rotate, meshes with the worm wheel 34 to make the shaft 33 rotate, and the diamond block 37 drives the second movable plate 36 to slide through the connecting plate 38, thereby causing the first movable plate 21 to drive the rope clamping plate 22 to clamp the wire rope. When the speed is normal, the motor 31 reverses and releases, thereby utilizing the self-locking performance of the worm 32 and worm wheel 34. When the motor 31 stops driving, the worm 32 and worm wheel 34 can remain relatively stationary, keeping the rope clamping plate 22 in a clamped state. This prevents the rope clamping mechanism from loosening due to unexpected factors (such as motor failure, power outage, etc.), further improving the safety and reliability of elevator operation.

[0030] A specific application of this embodiment is as follows: When it is necessary to disassemble the rope clamping plate 22, first loosen the bolt 211 and remove it. After the bolt 211 is removed, the fixing plate 210 loses its fixation, and the spring 29 returns to its original position and contracts under its own elastic potential energy, thereby driving the connecting piece 28 to move. When the connecting piece 28 moves, it drives the positioning pin 27 to move, so that the end of the positioning pin 27 inserted into the I-shaped block 23 is disengaged from the I-shaped block 23. Then, the rope clamping plate 22 is moved away from the moving plate 21, so that the rope clamping plate 22 drives the I-shaped block 23 to disengage from the I-shaped groove 24, and the rope clamping plate 22 can be disassembled. When installing the rope clamping plate 22, first loosen the bolt 211 and remove it. The I-shaped block 23 on the rope plate 22 is inserted into the I-shaped groove 24 on the moving plate 21. Then, the fixing plate 210 is pressed, causing the fixing plate 210 to move the positioning pin 27. This allows the end of the positioning pin 27 away from the fixing plate 210 to be inserted into the I-shaped groove 24, limiting the movement of the I-shaped groove 24. When the positioning pin 27 moves, it also moves the connecting piece 28. The movement of the connecting piece 28 then stretches the spring 29. Finally, the fixing plate 210 is fixed to the mounting plate 25 by the bolt 211, so that the fixing plate 210 and the positioning pin 27 cannot move. This completes the installation of the rope clamping plate 22.

[0031] When the elevator speed exceeds the speed limit, the control system starts the motor 31. The output shaft of the motor 31 drives the worm gear 32 to rotate. The worm gear 32 meshes with the worm wheel 34, causing the worm wheel 34 and the connected shaft 33 to rotate. The diamond block 37 on the shaft 33 rotates accordingly, pushing or pulling the second moving plate 36 through the connecting plate 38, so that it slides under the guidance of the first guide rod 35 and the guide groove 39. The movement of the second moving plate 36 is transmitted to the first moving plate 21 through the slider 311 and the second guide rod 310, so that the two moving plates 21 move closer to each other, causing the rope clamping plate 22 to clamp the elevator wire rope, thereby limiting the elevator speed. When the elevator speed returns to normal, the motor 31 reverses, causing the rope clamping plate 22 to release the wire rope.
