Description

Technical Field

[0001] The invention relates to an elevator roller guide shoe, and more particularly to an elevator roller guide shoe adjusting device. Background Art

[0002] Due to the high speed of high-speed elevators, the nylon slider guide shoe lining cannot resist the wear at high speed. Therefore, in order to meet the relative movement friction between the car and the guide rail of the high-speed elevator, a roller guide shoe is used to replace the nylon slider in the rolling friction movement on the guide rail. At the same time, it also reduces the noise generated by the friction between the guide rail and the guide shoe during operation, but it requires higher quality for the adjustment of the guide rail, and also increases the manufacturing cost of the elevator.

[0003] Most of the roller guide shoes in the prior art are adjustable elastic roller guide shoes, that is, a pressure spring is arranged beside the roller to limit the combination posture of the roller and the elevator guide rail, and an adjusting nut is arranged on the pressure spring, and the combination posture of the roller and the elevator guide rail can be adjusted by screwing the adjusting nut.

[0004] In actual use of the elevator, due to the uneven load inside the elevator, the elevator's posture will shift in one direction, and the combination posture of the roller guide shoe at the offset end and its matching guide rail will change. At this time, it is necessary to manually climb to the roller guide shoe at the top of the elevator when the elevator is stopped to adjust the pressure spring so that the combination posture of the roller and the elevator guide rail is restored. Each time the pressure spring is adjusted, an elevator maintenance test needs to be performed. Therefore, in the process of completely restoring the combination posture of the wheel and the elevator guide rail, the elevator needs to be stopped many times and the manual climb up the elevator many times to adjust the pressure spring, which is time-consuming and labor-intensive, and the safety factor needs to be improved. Summary of the invention

[0011] By adopting the above technical solution, after the employee installs the device on the roller guide shoe, the employee can remotely control the device to remotely adjust the roller guide shoe, which is convenient and safe.

[0012] The present invention is further configured such that a reduction gearbox is disposed in the housing, the servo drive component is transmission-connected to the clamp component via the reduction gearbox, and the reduction gearbox is disposed between the clamp pile and the fixed pile.

[0013] By adopting the above technical solution, the reduction box can increase the torque output by the clamp, thereby helping to reduce the volume of the servo drive component, and the location of the reduction box is also conducive to reducing the volume of the device.

[0014] The present invention is further configured such that a power connection point between the servo drive and the reduction box is close to a power connection point between the reduction box and the clamp, and is also close to the screw nut.

[0016] The present invention is further configured such that a power connection point between the servo drive and the reduction box, a power connection point between the reduction box and the clamp, and the screw nut are coplanar.

[0017] By adopting the above technical solution, the power connection point is coplanar with the screw nut, so that there is no recoil offset that deviates from the coplanarity on the device, which helps to ensure that the posture of the device on the roller guide shoe remains unchanged.

[0018] The present invention is further configured such that a clamping groove is provided on a side of the fixing pile away from the clamping pile.

[0027] By adopting the above technical solution, the fixing part absorbs the roller guide shoe and presses the reinforcing rib toward the roller guide shoe. The fixing part does not directly contact the roller guide shoe, thereby increasing its service life. The reinforcing rib is close to or attached to the roller guide shoe due to the pressure of the fixing part, and is more difficult to deform due to external force when the device is screwed, thereby increasing the degree of reinforcement of the reinforcing rib.

[0033] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] An elevator roller guide shoe adjustment device, such as Figure 1 and Figure 2As shown, it includes a housing 1 made of metal material, a clamping pile 2 is provided in one end of the housing 1, and a fixing pile 3 is provided in one side of the clamping pile 2, that is, the other end of the housing 1. The fixing pile 3 is used to clamp the protruding part on the roller guide shoe, and the ends of the housing 1 close to the clamping pile 2 and the fixing pile 3 are both set as arc-shaped ends. The clamping pile 2 and the fixing pile 3 work together to keep the posture of the housing 1 on the roller guide shoe unchanged. A clamping member 4 for clamping a screw nut is rotatably connected in the housing 1, and the clamping member 4 can be a sleeve for adjusting the screw nut on the pressure spring. After the housing 1 is installed on the roller guide shoe, the sleeve is sleeved on the screw nut. A threaded hole is opened on the housing or the clamping pile 2, and a positioning bolt 15 can be connected by bolts. The end of the positioning bolt 15 away from the housing 1 is welded or bolted with an auxiliary bracket 16, and the auxiliary bracket 16 can be directly welded or bolted to the roller guide shoe. Auxiliary bolts 17 are welded or bolted to the auxiliary bracket 16, and the auxiliary bolts 17 are used to connect with the fixing piles 3. The auxiliary bracket 16 fixes the position of the housing 1 on the roller guide shoe. In other cases, the housing 1 may only be provided with clamping piles 2 without fixing piles 3, and the clamping piles 2 are fixedly connected to the auxiliary bracket 16 by positioning bolts 15. In other cases, such as Figure 2 As shown, a threaded hole is provided on the housing 1, a positioning bolt 15 is threadedly connected to the threaded hole and an auxiliary bracket 16 is connected via the positioning bolt 15, and the auxiliary bracket 16 is fixedly connected to the roller guide shoe via two bolts, thereby fixing the housing 1 on the roller guide shoe.

[0035] like Figure 1 and Figure 3 As shown, an adjustment component 5 for providing power for rotating the screw nut is provided next to the clamp pile 2, and the adjustment component 5 includes a reduction box 6, a servo driver 7, a controller 8 and a first wireless module 9 connected in sequence. The servo driver 7 can be a servo motor or a servo stepper motor, and the reduction box 6 is arranged in the housing 1. The servo driver 7 is connected to the clamp 4 through the reduction box 6 to drive the clamp 4 to rotate. In some other cases, the reduction box 6 is arranged between the clamp pile 2 and the fixed pile 3. The reduction box 6 can increase the torque output by the clamp 4, thereby helping to reduce the volume of the servo driver 7, and the position of the reduction box 6 is also conducive to reducing the volume of the device. The power connection point between the servo driver 7 and the reduction box 6 is close to the power connection point between the reduction box 6 and the clamp 4, and is also close to the screw nut, shortening the power transmission path and improving the power transmission efficiency. In some other cases, the power connection point between the servo drive 7 and the reduction box 6, the power connection point between the reduction box 6 and the clamp 4, and the screw nut are coplanar. The power connection point and the screw nut are coplanar, so that there is no recoil offset that deviates from the coplanarity on the device, which helps to ensure that the posture of the device on the roller guide shoe remains unchanged.

[0036] The controller 8 can adopt the MSP430 series low-power single-chip microcomputer, and can drive the servo motor or servo stepper motor through the built-in communication protocol to realize the control of the rotation direction and speed of the driving part. The controller 8 sends or receives data information through the first wireless module 9. The first wireless module 9 can select the 2.4GHz NRF24101 wireless module or the 433MHz wireless module for wireless communication. The communication protocol and other technical information of the above wireless modules are all prior art, which will not be repeated in this article. The controller 8 can also send or receive data information through the first wired module. The first wired module can select the CAN bus module or the RS485 bus module for wireless communication. The communication protocol and other technical information of the above wired modules are all prior art, which will not be repeated in this article. The servo driving part 7 is located in a protruding part, and the protruding part is glued with the antenna of the first wireless module 9. The antenna is arranged on the protruding part to better generate or receive electromagnetic wave signals. The protruding part can also be welded or the cable of the first wired module. The cable is arranged on the protruding part and will not affect the transmission of the signal. The device also includes a control terminal 10, which can be made of an Android smartphone or a mobile platform device. The control terminal 10 is electrically connected to a second wireless module 11 or a second wired module, and the first wireless module 9 is paired with the second wireless module 11, or the first wired module is paired with the second wired module. The control terminal 10 sends or receives data information through the second wireless module 11 or the second wired module. After the employee installs the device on the roller guide shoe, it can be remotely controlled to remotely adjust the roller guide shoe, which is convenient and safe.

[0037] A clamping groove 12 is provided on the side of the fixing pile 3 away from the clamping pile 2. The opening direction of the clamping groove 12 is away from the clamping pile 2. The clamping groove 12 can facilitate the fixing pile 3 to be clamped or disengaged from the protrusion on the roller guide shoe, and can also provide deformation within the allowable range when the screw nut is rotated, so that the servo drive 7 produces a preliminary displacement, which is conducive to the servo drive 7 to continue to rotate the screw nut. A fixing piece 13 for fixing it on the roller guide shoe is welded on the housing 1. The roller guide shoe is made of iron. The fixing piece 13 can be made of a neodymium magnet and adsorbed on the roller guide shoe, so that the device is more stable after being installed on the roller guide shoe. The fixing piece 13 is welded between the protrusion and other parts of the housing 1. The fixing piece 13 can strengthen the structural strength between the protrusion and other parts of the housing 1. A reinforcing rib 14 is welded between the protrusion and other parts of the housing 1. At the same time, the fixing piece 13 is welded and fixed to the reinforcing rib 14, and the reinforcing rib 14 is located between the fixing piece 13 and the roller guide shoe. The fixing member 13 absorbs the roller guide shoe and presses the reinforcing rib 14 toward the roller guide shoe. The fixing member 13 does not directly contact the roller guide shoe, and no friction is generated, thereby increasing the life of the roller guide shoe. The reinforcing rib 14 can be close to or attached to the roller guide shoe under the pressure of the fixing member 13, which increases the difficulty of the reinforcing rib 14 to deform away from the roller guide shoe, thereby increasing the degree of reinforcement of the reinforcing rib 14.

[0038] The implementation principle of this embodiment is as follows: when the employee uses it, he first climbs onto the top of the car and installs the housing 1 on the roller guide shoe. The clamping pile 2 is installed on the screw nut, and the fixing pile 3 is clamped on the protruding part of the roller guide shoe, so that the housing 1 is fixed on the roller guide shoe and the posture of the housing 1 remains unchanged, wherein the power connection point for transmitting power is coplanar with the screw nut, so that the device does not have a recoil offset that deviates from the coplanarity, and the housing 1 of the device does not have a twist deformation on the roller guide shoe, so as to ensure the stable operation of the device. The fixing part 13 can also improve the stability of the reinforcing rib 14, so that the device will not deviate from the screw nut when it moves, and improve the working stability. The employee operates the control terminal 10, and the control terminal 10 sends data information to the first wireless module 9 through the second wireless module 11, and the controller 8 receives remote data information through the first wireless module 9. Alternatively, the employee operates the control terminal 10, and the control terminal 10 sends data information to the first wired module through the second wired module, and the controller 8 receives remote data information through the first wired module. Then the servo motor is controlled, and the servo motor drives the clamp 4 through the reduction box 6 to rotate the screw nut, so as to realize remote adjustment, which is highly safe. When the screw nut needs to be adjusted multiple times, there is no need to climb onto the car top, and the adjustment process is simple. After the adjustment is completed, the elevator is stopped, and then the device can be removed by climbing onto the car top.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
