Description

Technical Field

[0001] This application relates to the field of elevators, and more particularly to a silent elevator safety clamp. Background Technology

[0002] An elevator safety clamp is a safety device that, under the control of the speed governor, brings the elevator car to an emergency stop and clamps it onto the guide rails when the elevator speed exceeds the speed limit (or rated speed) set by the speed governor, or in the event of a breakage or slack in the suspension rope. It provides effective protection for the safe operation of the elevator and is typically installed on the car frame or counterweight frame.

[0003] Among the many safety components of an elevator, the safety clamp plays a crucial role. The main function of the safety clamp is to quickly clamp the guide rails and stop the elevator when it is overspeeding or descending out of control, thereby protecting the lives of passengers. However, traditional elevator safety clamps often generate a lot of noise during operation, which not only affects the passenger's riding experience but may also have a negative impact on the overall performance of the elevator. Utility Model Content

[0004] To reduce the noise generated, this application provides a silent elevator safety clamp.

[0005] The silent elevator safety clamp provided in this application adopts the following technical solution:

[0006] The clamp includes a fixed plate fixedly installed on one side of the clamp body. The inner side of the clamp body is provided with rollers, and two rubber rings are sleeved on the outer side of the rollers. A fixed shaft is fixedly installed on one side of the rollers. The inner side of the clamp body is provided with a guide groove for guiding the movement direction of the fixed shaft. The inner side of the clamp body is provided with a placement groove for accommodating the rollers. A circular hole is opened on the other side of the rollers, and an installation head is fixedly sleeved on the inner side of the circular hole.

[0007] By adopting the above technical solution, the fixed installation of the fixed plate and the clamp body allows the roller to move in the placement groove. The mounting head installed on one side of the fixed plate can restrict the movement of the roller. By setting a rubber ring, it is easy to install a rubber ring on the outside of the roller, which can effectively reduce the friction noise and vibration noise generated when the clamp body is in direct contact with the elevator guide rail.

[0008] Preferably, a mounting hole is provided on one side of the clamp body, and a fixing bolt is threaded on the inner side of the mounting hole. The fixing plate is fixedly installed to the clamp body by the fixing bolt.

[0009] By adopting the above technical solution, the fixing plate and the clamp body can be fixed together by setting fixing bolts, and the roller can be stored inside the placement groove, so that the roller can be guided along the guide groove between the clamp body and the fixing plate.

[0010] Preferably, the surface of the fixing plate is provided with a strip-shaped groove corresponding to the guide groove, and the mounting head passes through the strip-shaped groove and is fixedly sleeved with the roller.

[0011] By adopting the above technical solution, and by setting guide grooves and strip grooves, the roller can be guided along the guide grooves and strip grooves between the clamp body and the fixed plate.

[0012] Preferably, the clamp body has a through groove for the guide rail to pass through, the through groove is connected to the placement groove, and the guide groove is connected to the placement groove.

[0013] By adopting the above technical solution, when the elevator is overspeeding or descending out of control, the rollers move along the guide groove and the slotted opening to quickly clamp the guide rail passing through the through groove, thereby stopping the elevator and protecting the lives of passengers.

[0014] Preferably, a first magnetic field generator is fixedly installed on the inner side of the clamp body, and a first mounting groove for installing the first magnetic field generator is provided on the inner bottom of the clamp body.

[0015] By adopting the above technical solution, and by setting a first magnetic field generator, the magnetic force of the first magnetic field generator can attract the roller to move and reset, thereby turning off the brake on the elevator when there is no fault.

[0016] Preferably, a second magnetic field generator is fixedly installed on the inner side of the clamp body, and a second mounting groove for installing the second magnetic field generator is provided on the top of the clamp body.

[0017] By adopting the above technical solution and setting a second magnetic field generator, the magnetic force of the second magnetic field generator can attract the roller to clamp the guide rail, thereby activating the braking of the elevator when a malfunction occurs.

[0018] Preferably, the first mounting slot is connected to the placement slot, and the second mounting slot is connected to the placement slot.

[0019] By adopting the above technical solution, the top of the first mounting groove is connected to the placement groove to ensure that the magnetic force of the first magnetic field generator can attract the roller to move, and the bottom of the second mounting groove is connected to the placement groove to ensure that the magnetic force of the second magnetic field generator can attract the roller to move.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] The design incorporates rubber rings on the outer side of the rollers. Rubber, as a soft and elastic material, can effectively absorb and isolate noise and vibration. When the clamp body contacts the guide rail, the rubber rings reduce the direct contact area between the metal parts, thereby reducing friction and vibration noise. By placing rubber rings on the outer side of the rollers, the friction and vibration noise generated when the clamp body directly contacts the elevator guide rail or other metal parts is effectively reduced, providing passengers with a quieter and more comfortable riding experience.

Detailed Implementation

[0028] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0029] This application discloses a silent elevator safety clamp, including a fixing plate 2 fixedly installed on one side of the clamp body 1. A roller 8 is provided on the inner side of the clamp body 1. Two rubber rings 16 are sleeved on the outer side of the roller 8. A fixing shaft 15 is fixedly installed on one side of the roller 8. A guide groove 6 for guiding the movement direction of the fixing shaft 15 is provided on the inner side of the clamp body 1. A placement groove 7 for accommodating the roller 8 is provided on the inner side of the clamp body 1. A circular hole 17 is opened on the other side of the roller 8. An installation head 9 is fixedly sleeved on the inner side of the circular hole 17.

[0030] Reference Figure 1 , Figure 2The clamp body 1 has a mounting hole 14 on one side, and a fixing bolt 3 is threaded on the inner side of the mounting hole 14. The fixing plate 2 is fixedly installed to the clamp body 1 by the fixing bolt 3.

[0031] The fixed installation of the fixing plate 2 and the clamp body 1 allows the roller 8 to move within the placement groove 7. The mounting head 9 installed on one side of the fixing plate 2 restricts the movement of the roller 8. The rubber ring 16 is installed on the outside of the roller 8, which effectively reduces the friction and vibration noise generated when the clamp body 1 is in direct contact with the elevator guide rail. The fixing bolt 3 fixes the fixing plate 2 and the clamp body 1 together, and the roller 8 is housed inside the placement groove 7, allowing the roller 8 to move along the guide groove 6 between the clamp body 1 and the fixing plate 2.

[0032] Reference Figure 1 , Figure 2 The surface of the fixing plate 2 is provided with a strip-shaped slot 4 corresponding to the guide groove 6. The mounting head 9 passes through the strip-shaped slot 4 and is fixedly sleeved with the roller 8. The inner side of the clamp body 1 is provided with a through groove 5 for the guide rail to pass through. The through groove 5 communicates with the placement groove 7, and the guide groove 6 communicates with the placement groove 7.

[0033] By setting the guide groove 6 and the strip groove 4, the roller 8 can be guided along the guide groove 6 and the strip groove 4 between the clamp body 1 and the fixed plate 2. When the elevator overspeeds or descends out of control, the roller 8 moves along the guide groove 6 and the strip groove 4 to quickly clamp the guide rail passing through the through groove 5, so as to stop the elevator and protect the lives of passengers.

[0034] Reference Figure 1 , Figure 2 A first magnetic field generator 10 is fixedly installed on the inner side of the clamp body 1, and a first mounting groove 12 for installing the first magnetic field generator 10 is opened at the bottom inner side of the clamp body 1; a second magnetic field generator 11 is fixedly installed on the inner side of the clamp body 1, and a second mounting groove 13 for installing the second magnetic field generator 11 is opened at the top of the clamp body 1.

[0035] By setting a first magnetic field generator 10 and a second magnetic field generator 11, the magnetic force of the first magnetic field generator 10 can attract the roller 8 to move and reset, thus closing the brake on the elevator when there is no fault. The magnetic force of the second magnetic field generator 11 can attract the roller 8 to move and clamp the guide rail, thus activating the brake on the elevator when a fault occurs.

[0036] Reference Figure 1 , Figure 2 The first mounting slot 12 is connected to the placement slot 7, and the second mounting slot 13 is connected to the placement slot 7.

[0037] The first mounting groove 12 is connected to the placement groove 7 at its top, ensuring that the magnetic force of the first magnetic field generator 10 can attract the roller 8 to move. The second mounting groove 13 is connected to the placement groove 7 at its bottom, ensuring that the magnetic force of the second magnetic field generator 11 can attract the roller 8 to move.

[0038] The implementation principle of a silent elevator safety clamp according to an embodiment of this application is as follows: In use, the fixed shaft 15 at one end of the roller 8 is installed in the guide groove 6. Then, the fixing plate 2 is fixedly installed on one side of the clamp body 1 by rotating the fixing bolt 3. Then, the mounting head 9 is fixedly connected to the round hole 17 on one side of the roller 8 through the strip groove 4. The first magnetic field generator 10 is installed in the first mounting groove 12, and the second magnetic field generator 11 is fixedly installed in the second mounting groove 13. When the elevator overspeeds or descends out of control, the magnetic force of the second magnetic field generator 11 attracts the roller 8 to move and clamp the guide rail, thus braking the elevator. When the elevator is fault-free, the magnetic force of the first magnetic field generator 10 can attract the roller 8 to move and reset, so that the elevator can operate normally.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
