Description

Technical Field

[0001] This utility model relates to the field of traction machine manufacturing technology, specifically to a traction machine grinding brake and loading test equipment. Background Technology

[0002] After assembling the brakes, the traction machine exhibits the following problems: First, due to positional errors in component manufacturing and misfitting between the brake shoes and the brake wheel's arc surface, the percentage of contact between the mating surfaces is insufficient, affecting the braking torque. Second, the brake clearance during production and commissioning differs from the actual clearance after the elevator is in use and loaded. A larger clearance results in excessive brake noise, while a smaller clearance poses a risk of brake dragging. Therefore, the braking torque and clearance of the traction machine must meet both standard and application requirements upon leaving the factory. Utility Model Content

[0003] The purpose of this invention is to provide a traction machine brake grinding and loading test device for detecting the performance of the brake and traction machine after assembly.

[0004] The purpose of this utility model is achieved as follows.

[0005] A traction machine brake wear and loading test device includes a base. A reducer and a load cell are mounted on one side of the base, with the pressure surface of the load cell contacting the reducer. A motor connecting plate is driven to the reducer facing a positioning platform. A positioning platform is mounted on the other side of the base for mounting the traction machine via a fastening mechanism. A first bearing housing, a servo cylinder, and a tension sensor are located between the reducer and the positioning platform on the base. The tension sensor is connected to one end of a hanging belt, and the other end of the hanging belt is connected to the actuating end of the servo cylinder. The hanging belt forms a accommodating position for placing the traction machine. A splined connecting plate is horizontally rotatably mounted on the first bearing housing, with one end of the splined connecting plate driven to the motor connecting plate. The splined connecting plate has a splined shaft, and a sliding splined connecting plate is mounted on the splined shaft. The sliding splined connecting plate and / or the splined shaft can move axially. A control device is also mounted on the base, electrically connected to the reducer, the load cell, the servo cylinder, and the tension sensor. After the traction machine is installed, the control device has brake wear mode and loading mode.

[0006] Grinding Brake Mode: The servo electric cylinder moves to prevent the belt from contacting the traction machine, the sliding spline connecting plate moves to connect with the rotating part of the traction machine, and the reducer drives the traction machine to rotate and grind the brake. The reducer is pressurized by the rotation and oscillation of the balance sensor, and the grinding brake torque is displayed through the control device.

[0007] Loading mode: The sliding spline connecting plate moves to disengage from the traction machine, and the servo electric cylinder moves in the opposite direction to make the belt contact the traction machine for loading. Loading stops when the tension sensor reaches the set pressure to adjust the braking clearance.

[0008] This invention enables the testing of the braking torque of the traction machine and the actual clearance after loading, meeting the pre-delivery debugging requirements and improving production efficiency.

[0009] Furthermore, the base has a first clearance opening, through which the reducer's geared motor passes downwards. A motor connecting disc is provided at one end of the geared motor's shaft extension. The structure is simple, the appearance is clean, and implementation is easy.

[0010] Furthermore, the base is provided with a base on each side of the first clearance opening, and a second bearing seat is provided on the base. The two shaft ends of the geared motor are rotatably connected to the corresponding second bearing seats. The one shaft end of the geared motor facing the positioning table and the motor connecting plate are positioned between the second bearing seat and the first bearing shaft seat.

[0011] Furthermore, the base is equipped with a positioning block, the positioning block has a step, and the weighing sensor is mounted on the step, with the pressure surface of the weighing sensor in contact with the outer surface of the reducer. This prevents the weighing sensor from being subjected to impact forces.

[0012] Furthermore, the spline connecting plate is connected to the motor connecting plate via a set of tapered bolts and rubber rings. The spline connecting plate has spline holes, and the spline shaft is axially telescopically positioned within these holes. This allows for adjustments to accommodate different distances from traction machines of varying sizes, and is easy to make.

[0013] Furthermore, the sliding spline connecting plate is slidably mounted on the end of the spline shaft that extends from the first bearing housing toward the positioning table. The sliding spline connecting plate has at least one set of arc-shaped grooves, and at least one handle is provided on the side of the sliding spline connecting plate facing the reducer. The sliding spline connecting plate can slide axially, facilitating movement and connection with the traction machine.

[0014] Furthermore, the positioning platform is fixed to the base with bolts. The positioning platform has multiple sets of positioning holes, and at least one set of positioning holes contains two movable positioning pins. The positioning pins are used to position the traction machine and the positioning holes. The structure is compact and is conducive to fixing traction machines with various foot hole positioning sizes, that is, to achieve lateral limiting of the traction machine.

[0015] Furthermore, the fastening mechanism includes pressure plates disposed around the positioning platform, which are used to press the traction machine firmly onto the positioning platform. The pressure plates achieve vertical limiting of the traction machine.

[0016] Furthermore, the base has a second clearance opening corresponding to the receiving position. The servo cylinder and the tension sensor are respectively located on both sides of the centerline of the reducer and the positioning platform below the base. The tension sensor and the servo cylinder are positioned within the second clearance opening. The hanging strap is connected to the servo cylinder and the tension sensor respectively via connectors. Loading is easy, and the hanging strap is less prone to movement interference.

[0017] Furthermore, the control device is equipped with two reducer control buttons, two servo cylinder control buttons, an emergency stop button, and a display screen. The control device facilitates the control of the traction machine's brake grinding and the operation of the loading test equipment.

[0018] This invention enables the testing of the braking torque and actual clearance of traction machines after loading, meeting pre-shipment debugging requirements and improving production efficiency. The overall structure is rationally arranged and compact, capable of accommodating brake wear and loading test clearances for traction machines of different sizes, thus meeting usage requirements.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1, see Figure 1-4 As shown, a traction machine brake grinding and loading test device includes a base 1, a reducer 2, a positioning platform 3, a control device 4, a motor connecting plate 5, a spline connecting plate 6, a spline shaft 7, a sliding spline connecting plate 8, a servo electric cylinder 9, a tension sensor 100, a weighing sensor 200, a hanging belt 400, a first bearing seat 10, and a second bearing seat 13.

Specifically, the base 1 has a first clearance opening 11. Bases 12 are respectively provided on both sides of the base 1 corresponding to the first clearance opening 11. A second bearing seat 13 is fixed on the base 12. The reducer motor 21 of the reducer 2 passes through the first clearance opening 11 and faces downward. The two shaft ends of the reducer motor 21 are respectively provided with bushings 22 and motor connecting discs 5, and are rotatably connected to the corresponding second bearing seats 13.

A spline connecting plate 6 is horizontally rotatably mounted on the first bearing housing 10. The spline connecting plate 6 is connected to the motor connecting plate 5 via a set of tapered bolts and rubber rings 61. The spline connecting plate 6 has spline holes, and the spline shaft 7 is axially telescopically mounted on these holes. A sliding spline connecting plate 8 is slidably mounted on the end of the spline shaft 7 that extends from the first bearing housing 10 towards the positioning table 3. The sliding spline connecting plate 8 has three sets of arc-shaped grooves 81, and two handles 82 are located on the side of the sliding spline connecting plate 8 facing the reducer 2. The second bearing housing 13 and the first bearing housing 10 can be the same bearing housing.

[0027] A positioning platform 3 is provided on the other side of the base 1. The positioning platform 3 is used to install the traction machine 300 through a fastening mechanism. Specifically, the positioning platform 3 is fixed to the base 1 with bolts. The positioning platform 3 has multiple sets of positioning holes 31, and at least one set of positioning holes has two movable positioning pins 32. The positioning pins 32 are used to pass through the foot holes of the traction machine 300 and the positioning holes 31 for positioning, thereby achieving lateral displacement limitation of the traction machine 300. The fastening mechanism includes four sets of pressure plates 16 arranged around the positioning platform 3. The pressure plates 16 can be moved up and down by a cylinder. The pressure plates 16 are used to press the traction machine 300 tightly onto the positioning platform 3, thereby achieving vertical displacement limitation of the traction machine 300.

[0028] The servo cylinder 9 and the tension sensor 100 are positioned between the positioning platform 3 and the first bearing seat 10. The tension sensor 100 is connected to one end of the hanging belt 400, and the other end of the hanging belt 400 is connected to the actuating end of the servo cylinder 9. The hanging belt 400 forms a receiving position 401 for placing the traction machine 300. Specifically, the base 1 has a second clearance opening 17 corresponding to the receiving position 401. The servo cylinder 9 and the tension sensor 100 are respectively located on both sides of the centerline between the reducer 2 and the positioning platform 3 below the base 1 surface. The tension sensor 100 and the servo cylinder 9 are positioned within the second clearance opening 17. The hanging belt 400 is connected to the servo cylinder 9 and the tension sensor 100 respectively via connectors. There are two second clearance openings 17, one corresponding to the servo cylinder 9 and the other to the tension sensor 100. Alternatively, there may be only one second clearance opening 17, spanning the centerline, with both the servo cylinder 9 and the tension sensor 100 positioned within the same second clearance opening 17.

[0029] The control device 4 is electrically connected to the reducer 2, the load cell 200, the servo cylinder 9, and the tension sensor 100. The control device 4 is equipped with two control buttons for the reducer 2 (i.e., reducer 2 start button 41 and stop button 42), two control buttons for the servo cylinder 9 (i.e., servo cylinder 9 up button 43 or down button 44), an emergency stop button 45, and a display screen 40.

[0030] After installation, the traction machine 300 control device 4 has a brake-breaking mode and a loading mode.

[0031] Grinding mode: The servo cylinder 9 rises and moves to lift the belt 400, preventing it from contacting the traction machine 300. The mounting holes of the traction machine 300 are positioned with the two positioning pins 32. Four sets of pressure plates 16 press the traction machine 300. Three positioning screws 302 are evenly distributed on the traction sheave 301 of the traction machine 300. The hand grips the handle 82 to slide the sliding spline connecting plate 8 on the spline shaft 7 until it is in contact with the end face of the traction sheave 301. The reducer 2 is started, and the reducer 2 rotates and... The motor connecting plate 5, spline connecting plate 6, spline shaft 7 and sliding spline connecting plate 8 rotate. The three sets of arc grooves 81 and positioning screws 302 of the sliding spline connecting plate 8 limit each other. That is, the sliding spline connecting plate 8 drives the hub 303 of the traction sheave 301 to rotate relative to the brake 304 of the traction machine 300. Due to the reaction force, the reducer 2 rotates to pressurize the load cell 200. The display screen 40 displays the torque curve and torque value. When the torque reaches the standard, it stops automatically.

[0032] Loading mode: After the sliding spline connecting plate 8 moves to disengage from the traction machine 300 and the traction sheave 301, the servo cylinder 9 moves downward to bring the belt 400 into contact with the traction machine 300 for loading. That is, the belt 400 is driven by the connecting piece to apply simulated pressure to the traction sheave 301. The actual tension is fed back by the connected tension sensor 100. When the set pressure is reached, the loading stops, and the brake clearance is adjusted to ensure the clearance between the wheel hub 303 and the brake 304 is reached.
