Description

Technical Field

[0001] The present invention relates to the technical field of traction machine testing, and particularly relates to an automatic shaft alignment system for elevator traction machine testing. Background Art

[0002] An elevator traction machine is the power equipment of an elevator, mainly divided into two categories: geared traction machines and gearless traction machines. With the development of frequency conversion, motor design, and control technologies, permanent magnet synchronous gearless traction machines have gradually become the mainstream. It mainly consists of a motor, a traction wheel, a brake, a machine base, an encoder, etc., and the power is directly transmitted from the motor to the traction wheel.

[0003] The performance detection of elevator traction machines is an important task for the design and use of elevator traction machines, and it has received extensive attention in the industry. According to the requirements of the "Elevator Type Test Rules", each testing institution and manufacturing unit has designed and developed professional elevator traction machine testing devices to detect various functions of elevator traction machines. Due to the uniqueness of its structure, the elevator traction machine needs to be connected to the testing device, and generally a flange structure matching the traction wheel is used.

[0004] The current testing devices for elevator traction machines mainly consist of a companion motor, a speed reducer, sensors, and the traction machine to be tested, and the test device is fixed on the platform through various tooling such as pads, pressing blocks, and bolts. The installation and fixation work has the following difficulties:

[0005] (1) The center height of the test system is fixed, and only by adjusting the traction machine to be tested can the same height be achieved. It is necessary to install several pads with different specifications at the bottom of the permanent magnet synchronous gearless traction machine to be tested. The types of pads are required to be diverse and the process is cumbersome, and it is very difficult to adjust them to be exactly the same;

[0006] (2) In order to ensure the test accuracy, the coaxiality between the traction machine to be tested and the test device cannot be greater than 1 mm. Currently, the form of using a dial indicator is basically adopted, and it is necessary to continuously adjust the position of the traction machine to be tested to adapt to the test system. The traction machine to be tested is as light as 300 kg and as heavy as 4 - 5 tons. Despite the assistance of a cantilever crane or a traveling crane, there are still relatively high work intensity and operation risks, with a high difficulty coefficient and large work intensity, and the overall accuracy can only be barely qualified after completion. Summary of the Invention

[0007] The main purpose of the present invention is to overcome the problems of difficult adjustment of the center height of the test system and complex processes in the prior art, and provide an automatic shaft alignment system for elevator traction machine testing. In this system, the traction machine to be tested is convenient to move, can quickly and automatically realize the spatial positioning and accurate adjustment of the position of the traction machine to be tested, can meet the automatic shaft alignment of elevator traction machines of different models and specifications, significantly improve the system accuracy, greatly improve the work efficiency, and reduce the potential safety risks during work.

In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention. Embodiment

[0040] Please refer to Figure 1-2 , an automatic shaft alignment system for elevator traction machine testing, comprising:

[0041] Testing system: The testing system includes a DC loading motor 1. A sensor stabilizing shaft 3 is arranged on one side of the DC loading motor 1. A torque sensor 2 is arranged between the DC loading motor 1 and the sensor stabilizing shaft 3. A flange extending mechanism 4 is arranged on one side of the sensor stabilizing shaft 3. One end of the flange extending mechanism 4 is fixedly connected to a connecting flange 6, and a binocular vision scanner 9 is arranged above. The binocular vision scanner 9 includes a projector and two high-precision CCD cameras. The system space needs to be calibrated before the test starts.

[0042] Among them, a first mounting seat is fixedly installed below the DC loading motor 1 and the torque sensor 2. A second mounting seat is fixedly installed below the sensor stabilizing shaft 3. The outside of the flange extending mechanism 4 is connected and supported through a connecting seat, and the binocular vision scanner 9 is fixedly installed at the top of the connecting seat.

[0043] System under test: The system under test includes a tested traction machine 8. An installation plate 11 is arranged below the tested traction machine 8. A left-right adjustment mechanism 10 is fixedly installed above the installation plate 11, and a base 5 and a lifting platform 7 are fixedly installed below. The base 5 is fixedly installed at the four corner positions of the installation plate 11, and the lifting platform 7 is fixedly installed at the middle position of the installation plate 11. The bottom of the tested traction machine 8 is slidably connected to the installation plate 11 and is simultaneously arranged on the left-right adjustment mechanism 10. One side of the tested traction machine 8 is fixedly connected to the connecting flange 6.

[0044] The left-right adjustment mechanism 10 is used to adjust the left-right position of the tested traction machine 8, and the lifting platform 7 and the base 5 are used to adjust the up-down position of the tested traction machine 8, facilitating the alignment connection between the tested traction machine 8 and the connecting flange 6; among them, the lifting platform 7 is a hydraulic automatic lifting rod, and the base 5 adopts a 4-plunger structure.

[0045] Specifically, the binocular vision scanner 9 includes a projector and two high-precision CCD cameras. The system space needs to be calibrated before the test starts. The projector projects light spots and cooperates with a calibration plate to perform scans at different angles and positions, extract the spatial image for grayscale processing, and use Gaussian filtering for noise reduction. After binaryzation processing of the noise-reduced image, a binary image is obtained, and the overall spatial position coordinates are calculated (subsequently, the overall system space is stable, and the coordinate values of the testing system space are basically unchanged). The binocular vision scanner 9 is used to scan the tested traction machine 8 to achieve spatial positioning, and the lifting platform 7, the left-right adjustment mechanism 10, and the flange extending mechanism 4 are used to quickly and automatically adjust the tested traction machine 8 to the accurate spatial coordinate position.

[0046] The specific operation process is as follows:

[0047] Lift the tested traction machine 8 and hoist it to the middle position of the mounting plate 11, and then power it on so that the system can control its rotation;

[0048] Use the binocular vision scanner 9 to cooperate with the rotation of the traction wheel of the tested traction machine 8 to locate the spatial coordinate values of the tested traction machine 8 (mainly to locate the traction wheel of the tested traction machine 8. The 6 holes used for the installation of the traction wheel are used as spatial landmark points, and the spatial coordinates (X, Y, Z) of the traction wheel are calculated);

[0049] Compare the spatial coordinates (X, Y, Z) of the traction wheel with the spatial coordinate values of the system, and obtain the required spatial coordinate values (X1, Y1, Z1) to be moved after conversion;

[0050] Control the hydraulic device of the lifting platform 7. The control unit adjusts the pressure, speed, and position of the hydraulic pump station based on the full-closed-loop digital control method, and can transmit the current platform movement speed and position information in real time, and lift the platform by the distance Z1 to the specified position.

[0051] Control the four groups of left-right adjustment mechanisms 10 on the lifting platform. With the help of the servo motor 1005 controller, control the left-right adjustment mechanisms 10 to move left and right and adjust the attitude (deflection, etc.). Determine the displacement of the servo motor 1005 according to the spatial movement coordinate values, and then determine the pulses released by the servo driver, and move the tested traction machine 8 to the specified position (X1, Y1);

[0052] Control the flange extension mechanism 4. The flange extension mechanism 4 can extend and retract like a telescopic rod, and move the connecting flange 6 to the traction wheel of the tested traction machine 8. At this time, the tested traction machine 8 and the test system have completed the shaft alignment and connection hole position matching. Finally, it is necessary to manually connect and fix it with bolts. Embodiment

[0053] Please refer to Figure 1-4 , on the basis of the above embodiment, for the automatic shaft alignment system of the elevator traction machine, the left-right adjustment mechanism 10 includes two first convex blocks 1001, and the two first convex blocks 1001 are arranged in parallel and fixedly connected by a slide bar 1003. A lead screw 1007 is arranged in the middle of the first convex block 1001, and both ends of the lead screw 1007 are rotatably connected to the first convex block 1001;

[0054] A second convex block 1002 is also arranged between the two first convex blocks 1001. Both ends of the second convex block 1002 are slidably connected to the slide bar 1003, and the middle end is threadedly connected to the lead screw 1007. By rotating the lead screw 1007, the second convex block 1002 can slide on the slide bar 1003.

[0055] A connecting rod 1004 is fixed to the top end of the second convex block 1002. One end of the connecting rod 1004 passes through the inside of the top end of one of the first convex blocks 1001. The connecting rod 1004 is slidably connected to the first convex block 1001, and one end thereof is fixedly connected to the bottom end of the traction machine 8 to be measured. When the second convex block 1002 moves, it can drive the connecting rod 1004 to move, thereby pulling or pushing the traction machine 8 to be measured to move left and right on the mounting plate 11.

[0056] A speed reducer 1006 is provided at one end of the lead screw 1007. The speed reducer 1006 is fixedly installed on another first convex block 1001, and a servo motor 1005 is fixedly installed on one side thereof. Through the settings of the servo motor 1005 and the speed reducer 1006, the lead screw 1007 can be driven to rotate, so that the second convex block 1002 moves on the slide bar 1003, and then the traction machine 8 to be measured is pulled or pushed to move left and right on the mounting plate 11.

[0057] Furthermore, four sets of the overall components of the left and right adjustment mechanism 10 are provided and symmetrically distributed on both sides of the bottom end of the traction machine 8 to be measured. The connecting rods 1004 are all fixedly connected to the bottom end of the traction machine 8 to be measured. Under the action of the four sets of servo motors 1005 and speed reducers 1006, the four sets of lead screws 1007 can be simultaneously rotated synchronously, so that the second convex blocks 1002 move synchronously on the slide bar 1003, so as to apply force in the same direction to pull or push the traction machine 8 to be measured to move left and right on the mounting plate 11.

[0058] Specifically, in use, through the settings of the servo motor 1005 and the speed reducer 1006, the lead screw 1007 can be driven to rotate, so that the second convex block 1002 moves on the slide bar 1003. The second convex block 1002 can drive the connecting rod 1004 to move inside the top end of the first convex block 1001, thereby pulling or pushing the traction machine 8 to be measured to move left and right on the mounting plate 11.

[0059] Moreover, through the settings of the four sets of left and right adjustment mechanisms 10, with the help of the servo motor 1005 controller, the left and right adjustment mechanisms 10 can be independently controlled to cooperate with each other, so that the attitude of the traction machine 8 to be measured is adjusted (such as deflection, etc.).

[0060] The solutions in this embodiment can be selectively combined and used with the solutions in other embodiments. Embodiment

[0061] Please refer to Figure 3-4, on the basis of the above embodiments, in the automatic shaft alignment system for elevator traction machine testing, a front-back movement mechanism is provided between the mounting plate 11, the lifting platform 7 and the base 5. The front-back movement mechanism includes a load-bearing plate 12. The load-bearing plate 12 is arranged between the mounting plate 11, the lifting platform 7 and the base 5, and is fixedly connected to the lifting platform 7 and the base 5;

[0062] A slider 1211 and a slide rail 1212 are provided between one end of the load-bearing plate 12 and the mounting plate 11 for sliding connection. The slider 1211 is fixedly installed at the bottom of the mounting plate 11, and the slide rail 1212 is fixedly installed above the load-bearing plate 12.

[0063] A convex plate 1201 is fixedly connected above the other end of the load-bearing plate 12. A guide rod 1202 is slidably connected inside one end of the convex plate 1201, and a movable groove 1204 is provided. The guide rod 1202 penetrates through the movable groove 1204 and is slidably connected inside the convex plate 1201. One end of the guide rod 1202 is fixedly connected to the side wall of the mounting plate 11. A cushion block 1203 is fixedly connected to one side of the guide rod 1202, and the cushion block 1203 is flush with the notch of the movable groove 1204;

[0064] Two first movable rods 1205 are hinged to one side of the cushion block 1203. One ends of the two first movable rods 1205 are hinged in a V shape. A bent rod 1206 is hinged to one side of the first movable rod 1205. The bent part of the bent rod 1206 is hinged to a movable plate 1207. A second movable rod 1208 is hinged to one end of the movable plate 1207. One ends of the bent rod 1206 and the second movable rod 1208 are hinged by a clamping plate 1209; By moving the two clamping plates 1209 closer to or away from each other, the clamping plate 1209 can drive one end of the bent rod 1206 and the second movable rod 1208 to move closer to or away from each other.

[0065] The two bent rods 1206 are cross-arranged and are fixed above the convex plate 1201 through a rotating shaft at the middle position; Since the two bent rods 1206 are cross-hinged at the middle, the other ends of the bent rods 1206 move away from or close to each other in opposite directions, and thus, in cooperation with the first movable rod 1205, the mounting plate 11 is pulled or pushed to move back and forth.

[0066] Further, a through groove 1210 is provided inside the other end of the convex plate 1201, and the through groove 1210 is arranged corresponding to the position of the clamping plate 1209. Through the arrangement of the through groove 1210, it is convenient to fixedly connect the movable plate 1207 to the first moving plate 1301 and the second moving plate 1302.

[0067] Specifically, when in use, when the traction machine 8 to be measured needs to move in the direction of the connecting flange 6 in cooperation with the flange extending mechanism 4, by moving two clamping plates 1209 closer to or away from each other, the clamping plates 1209 can drive one end of the bending rod 1206 and the second movable rod 1208 to move closer to or away from each other. As a result, the other end of the bending rod 1206 moves away from or closer to in the opposite direction, and then, in cooperation with the first movable rod 1205, the mounting plate 11 is pulled or pushed to move back and forth, so that the traction machine 8 to be measured moves in the direction of the connecting flange 6, facilitating the connection with the connecting flange 6.

[0068] The solution in this embodiment can be selectively combined with the solutions in other embodiments for use. Embodiment

[0070] A upper toothed plate 1303 is fixedly connected to one side of the first moving plate 1301, and a lower toothed plate 1304 is fixedly connected to one side of the second moving plate 1302.

[0071] A driving gear 1305 is rotatably connected to the horizontal plate portion of the I-shaped plate 13. The driving gear 1305 is simultaneously meshed with the upper toothed plate 1303 and the lower toothed plate 1304. By rotating the driving gear 1305, it drives the upper toothed plate 1303 and the lower toothed plate 1304 to move in opposite directions, so that the first moving plate 1301 and the second moving plate 1302 move away from or close to each other, and thus the two clamping plates 1209 move away from or close to each other.

[0072] Furthermore, two groups of driving gears 1305 are provided, and the middle ends thereof are fixedly connected to a transmission rod 1309, one end of the transmission rod 1309 passes through the horizontal plate part of the I-shaped plate 13, and is fixedly connected to a driven pulley 1306, one side of the driven pulley 1306 is connected to the driving pulley 1308 through a belt transmission, and one side of the driving pulley 1308 is fixedly connected to a driving motor 1307, and the driving motor 1307 is fixed to the bottom of the load-bearing plate 12 through a base; the driving motor 1307 can drive the driving pulley 1308 to rotate, and then drive the driven pulley 1306 to rotate through the belt transmission, thereby driving the driving gear 1305 to rotate.

[0073] Specifically, during use, when the two clamping plates 1209 need to be moved closer to or away from each other, the driving motor 1307 is used to drive the active pulley 1308 to rotate, and then the belt transmission is used to drive the driven pulley 1306 to rotate, thereby driving the driving gear 1305 to rotate, and then the driving gear 1305 drives the upper toothed plate 1303 and the lower toothed plate 1304 to move in opposite directions, so that the first movable plate 1301 and the second movable plate 1302 move away from or closer to each other, thereby making the two clamping plates 1209 move away from or closer to each other, and finally, in cooperation with the front and rear moving mechanism, the tested winch 8 is moved toward the connecting flange 6, which is convenient for the connecting flange 6 to be connected.

[0074] The solution in this embodiment can be selectively combined with the solutions in other embodiments for use.
