Description

Technical Field

[0001] The utility model relates to the technical field of traction machine detection, and specifically, to a detection platform for rapid clamping of a traction machine. Background Art

[0002] Traditional elevator products are commonly used in public places. The number of products is relatively small and the unit price is relatively high, forming a relatively stable working mode of manual + mechanical assistance. Therefore, during the detection stage, the transformation and application of assembly line are not considered.

[0003] In recent years, with the improvement of people's living standards, the scale of the home elevator market has been continuously expanding. This kind of elevator has a relatively simple structure compared with shared elevators, relatively lower performance, and relatively lower cost, resulting in a certain scale production effect. However, the quality inspection process and standards of elevators are unified. For the quality inspection of traction machines, 100% load tests need to be completed. The efficiency of the traditional manual + mechanical assistance mode is insufficient, becoming a shortcoming in the production link of home elevators.

[0004] In the load test link of the traction machine, the assembly and combination of the traction machine and the test system are laborious and time-consuming. After the traction machine and the detection equipment are positioned, they need to be connected through a cross universal joint flange. Each time a test is performed, it needs to be disassembled and assembled once, which takes the most time. Therefore, it is necessary to design a more convenient detection platform to improve the positioning and connection efficiency, achieve rapid detection, and improve production efficiency. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, and thus provide a detection platform for rapid clamping of a traction machine, which improves the connection efficiency through a plug-in connection method, designs a positioning structure to ensure the installation accuracy, and ensures accurate positioning through sensor detection.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: a detection platform for rapid clamping of a traction machine, including a companion testing machine, a drive shaft assembly, a plug-in coupling, a linear slide table assembly, a test bench, and a ranging sensor;

[0007] The companion testing machine is installed on the test bench. The output shaft of the companion testing machine is drivingly connected to the drive shaft assembly. The drive shaft assembly is installed based on the test bench. One end of the plug-in coupling is connected to the output end of the drive shaft assembly;

[0008] The linear slide table assembly is installed on the test bench. The sliding direction of the linear slide table assembly is the same as the axial direction of the drive shaft assembly. The moving end of the linear slide table assembly is used to install the traction machine under test. The input shaft of the traction machine under test is connected to the other end of the plug-in coupling;

[0009] The ranging sensor is installed on the test bench and is used to detect the moving position of the linear slide assembly. The ranging sensor is linked with the power part of the linear slide so that after the two ends of the plug-in coupling are plugged and matched, the linear slide is stopped and locked.

[0010] Preferably, the accompanying test machine and the transmission shaft assembly are driven and connected through a universal coupling.

[0011] Preferably, a torque sensor is connected between the universal coupling and the transmission shaft assembly.

[0012] Preferably, the plug-in coupling includes a plug end and a socket end. The plug end is provided with a plurality of axially extending and circumferentially distributed plugs. The socket end is provided with a plurality of circumferentially distributed sockets. The positions of the plugs and the sockets match. The plug end is connected to the transmission shaft assembly, and the socket end is used to connect to the input shaft of the tested traction machine.

[0013] Preferably, the linear slide assembly includes an electric lead screw assembly and a linear guide rail assembly. The orientation of the linear guide rail assembly is the same as the axial direction of the transmission shaft assembly. The tested traction machine is installed on the movable carrier of the linear guide rail assembly through a Yanshao pin.

[0014] Preferably, the ranging sensor is installed at the end of the electric lead screw assembly.

[0015] Preferably, the ranging sensor is a laser rangefinder or an infrared rangefinder.

[0016] Preferably, the sensing probe of the ranging sensor is arranged facing the movable carrier of the linear guide rail assembly.

[0017] Preferably, the motor of the electric lead screw assembly is a motor with a self-locking function.

[0018] Preferably, a polyurethane sleeve is arranged on the contact surface between the plug end and the socket end of the plug-in coupling.

[0019] The utility model has substantial features and progress compared with the prior art. Specifically, the utility model uses a plug-in coupling to replace the traditional cross universal joint flange connection method, greatly improving the connection speed. The plug-in coupling itself has a certain positioning ability, saving the adjustment and positioning work after connection and improving the detection efficiency.

[0020] By setting the transmission form of the universal coupling and the transmission shaft assembly between the accompanying test machine and the tested traction machine, the positioning requirements are further reduced and the power transmission is more stable.

[0021] Adding a torque sensor can obtain torque information in real time and provide data support for the tested process.

[0022] The contact surface of the plug-in coupling is provided with a polyurethane sleeve, which plays a role in buffering and shock absorption.

[0023] The linear slide table assembly is used as the bearing device of the tested traction machine, which has a self-locking brake ability. Cooperating with the laser distance sensor, it can achieve high-precision positioning and ensure stability during the testing process.

[0024] The linear slide table uses an electric screw rod assembly and a linear guide rail in cooperation to carry a higher load.

[0025] The transmission shaft assembly has high rigidity, protects the torque sensor from the influence of system vibration, and the measurement is more accurate. Description of the Drawings

[0030] Next, through the detailed embodiment, the technical solution of the present utility model will be further described in detail.

[0031] As Figures 1-3 shown, a detection platform for a quick clamping of a traction machine includes a companion test machine 1, a universal coupling 2, a torque sensor 3, a transmission shaft assembly 4, a plug-in coupling 5, a linear slide table assembly, a test bench 8 and a distance sensor 10.

[0032] The companion test machine 1 is installed on the test bench 8. The output shaft of the companion test machine 1 is directly connected to the universal coupling 2. The other end of the universal coupling 2 is connected to the torque sensor 3. The other end of the torque sensor 3 is connected to the transmission shaft assembly 4. The other end of the transmission shaft assembly 4 is connected to the plug end of the plug-in coupling 5, forming a driving power assembly of the tested traction machine.

[0033] The linear slide assembly is installed on the test bench 8. In this embodiment, the linear slide assembly includes an electric lead screw assembly 7 and a linear guide rail assembly 9. The orientation of the linear guide rail assembly 9 is the same as the axial direction of the transmission shaft assembly 4. The traction machine 6 to be tested is installed on the movable stage of the linear guide rail assembly 9. In this embodiment, the linear guide rail assembly 9 adopts the HCW type and has a high load capacity.

[0034] The input shaft of the traction machine 6 to be tested is connected to the other end of the plug-in coupling 5.

[0035] In this embodiment, the plug-in coupling 5 includes a plug end 51 and a socket end 52. The plug end 51 is provided with a plurality of axially extending and circumferentially distributed plugs. The socket end 52 is provided with a plurality of circumferentially distributed sockets. The positions of the plugs and sockets match. The plug end 51 is connected to the transmission shaft assembly 4, and the socket end 52 is used to connect to the input shaft of the traction machine 6 to be tested.

[0036] Due to the frequent collision phenomenon during the loading and unloading process, a polyurethane sleeve is provided on the contact surface between the plug end and the socket end of the plug-in coupling to prevent collision damage.

[0037] The distance measuring sensor 10 is installed on the test bench 8 and is used to detect the moving position of the linear slide assembly. The distance measuring sensor 10 is a laser distance meter or an infrared distance meter.

[0038] Specifically, in this embodiment, the distance measuring sensor 10 is installed at the end of the electric lead screw assembly 7. The sensing probe of the distance measuring sensor 10 is arranged facing the movable stage of the linear guide rail assembly 9. The motor of the electric lead screw assembly 7 is a motor with a self-locking function.

[0039] The distance measuring sensor 10 is linked with the power part of the linear slide, that is, the motor of the electric lead screw assembly 7, so that after the two ends of the plug-in coupling 5 are plugged and matched, the linear slide is stopped and locked.

[0040] Working principle description:

[0041] After assembling the traction machine to be tested with the socket end of the plug-in coupling and placing it on the movable stage of the linear guide rail assembly 9, the anchor bolts are fixed by pin limits, which is convenient and fast. Then, control the servo motor to be powered on, control the electric lead screw assembly 7 to drive the linear guide rail assembly 9 to move, and the two ends of the plug-in coupling approach each other until they are plugged and connected.

[0042] At the same time, the laser distance sensor synchronously senses the moving position of the linear guide rail assembly 9. After reaching the set position, the servo motor is powered off and self-locked for braking. At this time, the plug-in coupling is fully mated, and the detection process can be started.

[0043] According to the detection procedure, the tested traction machine is subjected to a load test through the accompanying test machine.

[0044] After the detection is completed, the linear slide table assembly is operated in the reverse direction to remove the tested traction machine, and the detection of the next traction machine is carried out. The disassembly and assembly efficiency of the entire detection process is greatly improved compared with the traditional scheme.

[0045] Finally, it should be noted that the above has described the preferred embodiments of this patent in detail, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can also be made without departing from the gist of this patent.
