Description

Technical Field

[0001] This utility model relates to the field of elevator safety technology, and in particular to a steel belt fastening structure. Background Technology

[0002] An elevator typically consists of a car, counterweight, composite steel belt, and traction machine. The composite steel belt is used to pull the car and counterweight. The composite steel belt engages frictionally with the traction sheave, allowing the traction machine to drive its movement. Due to potential errors during elevator installation, the composite steel belt can easily slip out of the guide grooves of the guide sheaves during operation. Once out of the guide grooves, the composite steel belt deviates, severely abrading the sidewalls of the guide grooves. Furthermore, the composite steel belt itself also suffers wear from the guide grooves, reducing its lifespan and posing a safety hazard. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a steel strip fastening structure, which aims to solve the problem that the composite steel strip will deviate when it jumps out of the guide groove in the prior art.

The adjusting assembly is located on the frame, and the pressing wheel is connected to the adjusting assembly. The adjusting assembly is used to drive the pressing wheel to press the steel strip into the guide groove along the radial direction of the guide wheel.

[0005] Furthermore, the adjustment assembly includes an adjustment frame, a fixed shaft, and a threaded rod. The adjustment frame is mounted on the platform, and the adjustment frame has a groove extending radially along the guide wheel. The extrusion wheel is rotatably connected to the shaft of the fixed shaft, and the end of the fixed shaft slides in the groove. One end of the threaded rod extends into the groove and connects to the end of the fixed shaft, while the other end is threadedly connected to the adjustment frame. The threaded rod is used to screw to drive the fixed shaft to slide within the groove.

[0006] Furthermore, the adjusting frame includes an adjusting block, a fixing block, and a bolt. The slide groove is formed on the adjusting block, and the fixing block is fixed to the adjusting block by the bolt to close the open end of the slide groove. One end of the threaded rod is threadedly connected to the fixing block.

[0007] Furthermore, a limiting nut is provided at the end of the fixed shaft, which is used to limit the axial position of the extrusion wheel on the adjusting frame.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figures 1 to 5 This utility model provides a steel strip fastening structure, including a frame 1, a guide wheel 2, a steel strip 3, a pressing wheel 4, and an adjusting component 5. The guide wheel 2 is rotatably connected to the frame 1, and a guide groove 21 is provided on the guide wheel 2. The steel strip 3 is wound around the guide groove 21. The adjusting component 5 is provided on the frame 1, and the pressing wheel 4 is connected to the adjusting component 5. The adjusting component 5 is used to drive the pressing wheel 4 to press the steel strip 3 into the guide groove 21 along the radial direction of the guide wheel 2.

[0020] Specifically, the frame 1 is also equipped with a traction machine, and the guide wheel 2 is located on the power output end of the traction machine. Several guide grooves 21 are opened along the circumferential direction of the guide wheel 2. Correspondingly, several steel belts 3 are also provided. Due to differences in the installation environment when the steel belt 3 is wound around the guide wheel 2, the distance between the steel belt 3 and the extrusion wheel 4 varies. The adjusting component 5 can adjust the distance between the extrusion wheel 4 and the guide wheel 2, while ensuring the extrusion wheel 4 exerts sufficient pressure on the steel belt 3, avoiding excessive compression of the steel belt 3.

[0021] In one feasible embodiment, the adjusting assembly 5 includes an adjusting frame 51, a fixed shaft 52, and a threaded rod 54. The adjusting frame 51 is mounted on the platform 1 and has a groove 511 extending radially along the guide wheel 2. The extrusion wheel 4 is rotatably connected to the shaft of the fixed shaft 52, and the end of the fixed shaft 52 slides within the groove 511. One end of the threaded rod 54 extends into the groove 511 and connects to the end of the fixed shaft 52, while the other end is threadedly connected to the adjusting frame 51. The threaded rod 54 is used to screw to drive the fixed shaft 52 to slide within the groove 511. Specifically, a nut is welded to the adjusting frame 51, and the threaded rod 54 is threadedly connected to the nut. When the gap between the extrusion wheel 4 and the steel belt 3 is too large, screwing the threaded rod 54 pushes the fixed shaft 52 to slide within the groove 511, causing the extrusion wheel 4 to move closer to the steel belt 3. When the gap between the extrusion roller 4 and the steel belt 3 is too small, resulting in excessive extrusion force of the extrusion roller 4 on the steel belt 3, the screwing thread rod 54 drives the fixed shaft 52 to slide in the slide groove 511, so that the extrusion roller 4 moves away from the steel belt 3, and the pressure received by the steel belt 3 is kept at an appropriate level.

[0022] Further, the adjusting frame 51 includes an adjusting block 512, a fixing block 513, and a bolt 514. A groove 511 is formed on the adjusting block 512. The fixing block 513 is fixed to the adjusting block 512 by the bolt 514 to close the open end of the groove 511. One end of the threaded rod 54 is threadedly connected to the fixing block 513. In this embodiment, the groove 511 is formed along one side of the adjusting block 512 to facilitate the direct placement of the fixing shaft 52 into the groove 511 during installation. When the fixing shaft 52 is placed in the groove 511, the fixing block 513 is closed and fixed to the adjusting block 512 by the bolt 514. The fixing block 513 has a through hole through which the threaded rod 54 can pass.

[0023] In one feasible embodiment, a limiting nut 524 is provided at the end of the fixed shaft 52. The limiting nut 524 is used to limit the axial position of the extrusion wheel 4 on the adjusting frame 51. Specifically, both ends of the fixed shaft 52 are provided with limiting nuts 524. The limiting nuts 524 can effectively prevent the fixed shaft 52 from moving in its axial direction, thereby determining the position of the extrusion wheel 4 in the axial direction, so that it can better correspond to the position of the steel strip 3 and effectively prevent the steel strip 3 from shifting. Further, the edge of the extrusion wheel 4 is provided with a limiting protrusion 41 along its radial direction, and the limiting protrusion 41 corresponds to the edge of the steel strip 3.

[0024] In one feasible implementation, the platform 1 is equipped with a detection device 6, which is used to detect whether the steel strip 3 has shifted. Specifically, the detection device 6 can be a capacitive displacement sensor or a laser displacement sensor. When the steel strip 3 undergoes lateral displacement, the capacitance between the electrode of the capacitive displacement sensor and the steel strip 3 changes. As the steel strip 3 shifts, the change in capacitance value is detected by the sensor and converted into an electrical signal, thereby determining the amount of shift of the steel strip 3. The laser displacement sensor uses a laser beam emitter and receiver to determine the displacement of the steel strip 3 by measuring the change in distance between the laser beam and the surface of the steel strip 3. When the steel strip 3 undergoes lateral displacement, the position where the laser beam hits the surface of the steel strip 3 changes, and the time or intensity change of the reflected laser signal received by the sensor can be converted into the amount of displacement of the steel strip 3. When the detection device 6 detects that the steel strip 3 has shifted, it can issue an alarm in a timely manner to ensure the safe operation of the elevator.

[0025] In one feasible embodiment, the detection device 6 is equipped with a roller 61, which corresponds to the edge of the steel strip 3. This embodiment is applicable to a pressure position sensor. When the steel strip 3 undergoes lateral displacement, the roller 61 contacts the steel strip 3, and the steel strip 3 compresses the roller 61, causing the pressure position sensor to issue an alarm. The roller 61 reduces wear on the steel strip 3 caused by the detection device 6 when the steel strip 3 deviates.
