Description

Technical Field

[0001] The present invention relates to the field of testing of ground drive devices, and in particular to a testing platform for ground drive devices. Background Art

[0002] Oil production engineering is the process technology of lifting oil and gas from the bottom of the well to the wellhead. The ground drive device is a mechanical device used in oil production engineering to lift oil and gas from the bottom of the well to the wellhead. During the production process of the ground drive device, the test of the ground drive device is related to product performance and field use effect; in order to achieve the best performance, performance testing is required before leaving the factory to optimize the operating parameters of the drive device.

[0003] In order to ensure the production and maintenance quality of the ground drive device before leaving the factory, guarantee its use quality and improve its safety performance, the invention patent CN105201813A proposes a screw pump ground drive device test system and its use method. Although it can comprehensively test the performance of the screw pump ground drive device, it requires the operator to accurately and correctly fix the screw pump ground drive device to be tested before measurement, which is difficult to operate. If it is not fixed in place, the screw pump ground drive device to be tested will move during the test, which may cause inaccurate test results at the least and parts may fall off and splash, affecting the operator's life safety at the worst. Utility Model Content

[0004] The purpose of this solution is to provide a test platform for a ground drive device to solve the problem of difficulty in installing and operating the ground drive device and the test device when testing the ground drive device before leaving the factory.

[0005] In order to achieve the above-mentioned purpose, the present scheme provides a test platform for a ground drive device, comprising: a support frame, a prime mover and a ground drive device, the prime mover is fixedly connected to the support frame, a bearing seat is fixedly connected to the support frame, the bearing seat is coaxially rotatably connected to a pulley shaft, the pulley shaft is coaxially fixedly connected to a pulley, the belt of the pulley is windingly connected to the prime mover for transmission, the support frame is also fixedly connected to a torque meter, one end of the torque meter is fixedly connected to the pulley shaft, a mounting tray is slidably connected to the bottom end of the support frame, the mounting tray is fixedly connected to the ground drive device, a split coupling is fixedly connected between the ground drive device and the other end of the torque meter, the main body of the split coupling is fixedly connected to the other end of the torque meter, and the coupling sleeve of the split coupling is fixedly connected to the ground drive device.

[0006] The principle of this scheme is as follows: before the test, the ground drive device is fixedly connected with the mounting tray and the coupling sleeve of the split coupling, the ground drive device is slid into the inside of the support frame through the mounting tray, and the ground drive device is tightly fixedly connected with the torque meter through the split coupling; during the test, the prime mover drives the belt drive connected to the transmission, the belt drives the pulley to rotate, the pulley drives the coaxial fixedly connected pulley shaft to rotate, the pulley shaft transmits the torque force (rotational force) to the fixedly connected torque meter, and the torque meter collects the operating parameters of the ground drive device.

[0007] During the inspection, the prime mover and the torque meter are fixed on the support frame; the pulley shaft between the prime mover and the torque meter is limited in its movement range by the bearing seat, and the pulley and the pulley shaft can only rotate together; the support frame fixes the vertical distance between the mounting tray and the torque meter (fixes the installation range of the ground drive device), and the mounting tray fixes the horizontal direction and vertical distance of the ground drive device.

[0008] The technical effects of this solution are: (1) When the operator installs the ground drive device on the test device, he only needs to first fix the ground drive device on the installation tray, then fix the coupling sleeve of the split coupling on the ground drive device, and finally push the installation tray into the support frame to connect the coupling sleeve of the split coupling to the main body. Each of the above three steps is very simple, and the combination of the three steps is also very simple. It can be seen that this solution reduces the difficulty of installing the test device. (2) This solution fixes multiple components on the test device to the support frame, increases the fixation and support of the test device, and accurately limits the movement range of the test parts, making it difficult for components to fall off and splash during the test, thereby improving the safety of the operator's operating environment.

[0009] Furthermore, a step is provided on the bearing seat, a bearing is fixedly connected between the pulley shaft and the bearing seat, the bearing is fixedly connected to the step, and an axial keyway is provided on the pulley shaft, and the keyway is slidably connected to the pulley.

[0010] The bearing can limit the position of the pulley shaft on the bearing seat without affecting the rotation of the pulley shaft, which not only provides a stable rotation environment for the pulley shaft, but also prevents the pulley shaft from falling off and splashing; the step can prevent the pulley shaft from sliding off the bearing seat; the keyway makes the installation of the pulley easier and more accurate, and can fix the pulley and the pulley shaft more tightly, which is more conducive to the stable transmission of kinetic energy from the pulley to the pulley shaft. It further increases the stability of the test device operation, reduces the difficulty of the operator to install the test device, and improves the safety of the operator's operating environment.

[0011] Furthermore, it also includes a first universal joint and a second universal joint, wherein two ends of the first universal joint are respectively fixedly connected to the torque meter and the pulley shaft, and two ends of the second universal joint are respectively fixedly connected to the split coupling and the torque meter.

[0012] The universal joint can change the direction and angle of power transmission when transmitting power. When the fixed connection between the torque meter and the pulley shaft or the split coupling becomes loose, the universal joint can reduce the impact of the misalignment of the torque meter, the split coupling and the pulley shaft, and prevent the parts in the test device from falling off and splashing under high-speed operation, further improving the safety of the operator's operating environment and increasing the stability of the test device operation; at the same time, the universal joint can also play a role in buffering and shock absorption while transmitting rotational force to the torque meter, further increasing the stability of the test device operation.

[0013] Furthermore, it also includes a variable frequency intelligent control cabinet, which is electrically connected to the prime mover and the torque meter. The variable frequency intelligent control cabinet is mainly used to set the operation and protection parameters of the ground drive device under test, realize automatic measurement and control, and display the data transmitted by the torque meter.

[0014] The variable frequency intelligent control cabinet displays the data transmitted by the torque meter and the method thereof, which allows the operator to stay away from the detection device when the detection device is running, further improving the safety of the operator's operating environment; at the same time, the operating and protection parameters of the ground drive device under test are set to realize automatic measurement and control, which further simplifies the operator's test operation and improves the work efficiency of the test work.

[0015] Furthermore, the outer wall of the main body of the split coupling is provided with a first keyway, and the inner wall of the coupling sleeve of the split coupling is provided with a second keyway matching the first keyway; the coupling sleeve of the split coupling is a full diameter, the diameter of the coupling sleeve is slightly larger than the main body of the split coupling, and the outer wall of the coupling sleeve is fixedly connected with a handle.

[0016] The setting of the first keyway and the second keyway can intuitively reflect the relative position between the ground drive device and the torque meter, making it easy for the operator to observe and adjust the installation angle of the ground drive device, so that the ground drive device can be accurately installed in the detection device, improving the accuracy of the detection data of the detection device. The setting of the diameter and the handle can make the docking work of the coupling sleeve and the main body of the split coupling simpler and more accurate, so that the ground drive device can be accurately installed in the detection device, and further reduce the difficulty of the installation work.

[0017] Furthermore, protrusions are symmetrically arranged on the bottom of the coupling sleeve, and the curvature of the protrusions matches the groove of the main shaft of the ground driving device.

[0018] The raised setting can make the coupling sleeve and the ground drive device more closely fixed together, so that the ground drive device and the coupling sleeve are not easy to fall off and splash out when the detection device runs at high speed, further improving the safety of the operator's operating environment and increasing the stability of the test device operation.

[0019] Furthermore, a protective net is provided around the supporting frame, and the protective net is fixedly connected to the supporting frame.

[0020] When parts of the detection device accidentally fall off and splash, the protective net can prevent some parts from flying toward the operator and causing harm to the operator, further improving the safety of the operator's operating environment.

[0021] Furthermore, a slide rail is fixedly connected to the bottom end of the support frame, and the slide rail is slidably connected to the bottom of the mounting tray.

[0022] The setting of the slide rail makes it easy for the operator to install the point ground drive device on the test device; at the same time, the slide rail can also limit the lateral movement of the installation tray, increase the stability of the installation tray, thereby increasing the stable fixation of the ground drive device during the test process, so that the test device can read the operating data of the ground drive device more accurately.

[0023] Furthermore, a pulley protective cover is fixedly connected to the upper end of the pulley.

[0024] The pulley guard can prevent the belt from breaking during operation, and can also prevent foreign objects from falling into the area and causing accidents. BRIEF DESCRIPTION OF THE DRAWINGS
