Description

Technical Field

[0001] This utility model relates to the field of telescopic pole technology, specifically to a telescopic lifting test pole system. Background Technology

[0002] In radio frequency and microwave electromagnetic environment characteristic testing and some special test scenarios, it is necessary to raise the transmitting antenna to a certain height to reduce the reflection of electromagnetic waves on the ground in order to accurately collect the radiated electromagnetic environment of the transmitting antenna. Currently, commonly used antenna support devices include multi-section cylinders, multi-mast devices, and integral guide rail structures. Multi-section cylinders and multi-mast devices have simple structures and are easy to raise and lower, but their rigidity and stability are poor and cannot meet the requirement of the antenna being fixed at any height. The invention patent with authorization announcement number CN108953899B discloses a non-metallic vertical lifting test device, including a movable base and a retractable test rod on the base. The test rod is movably mounted on the base and is retracted and extended by a test rod retraction and unfolding mechanism. The test rod is extended and retracted by a lifting drive mechanism. Retractable support legs and fixing devices for fixing the base are symmetrically arranged on both sides of the base. This device can effectively realize the functions of fixing the test instrument, automatically adjusting the lifting height, and flexibly moving, and will not have an adverse effect on radio frequency microwave testing. However, the stability of the test rod is poor when it is extended to the highest point, and the roller is prone to wire tangling when winding and unwinding, requiring manual assistance in wire winding. Manual wire winding is dangerous and labor-intensive. Utility Model Content

[0003] The purpose of this invention is to provide a telescopic lifting test rod system, which solves the problems of poor stability when the existing test rod is extended to its highest point, easy wire tangling during the winding and unwinding of the roller, and the need for manual assistance in wire winding operations.

[0004] It can achieve electric lifting, has good cable laying and telescopic length measurement capabilities, good overall stability, simple and compact structure, simple and convenient lifting operation, and strong practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A telescopic lifting test rod system includes a support base, an electric roller mounted on top of the support base, and a telescopic rod assembly mounted on top of the support base. The electric roller and the telescopic rod assembly are connected by a telescopic control rope. A combing assembly is also mounted on top of the support base. The combing assembly includes a combing bracket mounted on top of the support base, a lead screw motor fixedly mounted on top of the combing bracket, a slide rail fixedly mounted on top of the combing bracket, a slider powered to the output end of the lead screw motor, and a combing shaft rotatably mounted on the slider. The slider is slidably mounted on the slide rail and reciprocates along the slide rail under the drive of the lead screw motor. The telescopic control rope passes through the combing shaft.

[0006] Preferably, an auxiliary support assembly is also provided on the top of the support base, and four sets of the auxiliary support assembly are arranged at circumferential intervals along the telescopic rod assembly.

[0007] Preferably, the auxiliary support assembly includes an auxiliary mounting base, an auxiliary drive motor fixedly mounted on the top of the auxiliary mounting base, a grooved wheel fixedly mounted on the output shaft of the auxiliary drive motor, and a tension rope disposed in the grooved wheel. One end of the tension rope is disposed on the top of the telescopic rod assembly via a connector.

[0008] Preferably, a tension sensor is provided on the connector, and one end of the tension rope is connected to the tension sensor. The tension sensor is used to measure the tension value when the tension rope is tensioned.

[0009] Preferably, the electric roller includes a base support, a main drive geared motor fixedly installed on the top of the base support, and a roller fixedly installed on the output shaft of the main drive geared motor, with the telescopic control rope wound around the roller.

[0010] Preferably, the telescopic pole assembly includes multiple pole cylinders that are sequentially nested from the outside to the inside. Adjacent pole cylinders are slidably connected by guide sliders. A guide pulley is provided at the top of the pole cylinder, and a transition hole is provided at the bottom of the pole cylinder. The telescopic control rope passes through the guide pulley at the top of the outermost pole cylinder, then through the transition hole at the bottom of the innermost pole cylinder, and then around to the second guide pulley. This process is repeated sequentially around the pole cylinders and then fixedly connected to the transition hole at the bottom of the innermost pole cylinder.

[0011] In this invention, the combing assembly can comb the rope during the electric drum's winding process, ensuring the telescopic control rope is neatly arranged on the electric drum. This results in good combing performance and reduces manual rope arrangement. Four sets of auxiliary support components are arranged circumferentially around the telescopic rod assembly to provide auxiliary fixation, ensuring good stability after extension.

[0013] The present invention will be further described below with reference to the accompanying drawings: like Figure 1 , Figure 2 , Figure 3 and Figure 4 The system illustrates a telescopic lifting test rod system, comprising a support base 1, an electric roller 2 mounted on top of the support base 1, and a telescopic rod assembly 3 mounted on top of the support base 1. The electric roller 2 and the telescopic rod assembly 3 are connected by a telescopic control rope 4. The electric roller 2 includes a base bracket 20 fixedly mounted on top of the support base 1, a main drive geared motor 21 fixedly mounted on top of the base bracket 20 by fasteners, and a roller 22 fixedly mounted on the output shaft of the main drive geared motor 21. One end of the telescopic control rope 4 is wound around the roller 22. The system also includes a controller, through which the operator controls the forward and reverse rotation and rotation speed of the main drive geared motor 21 to control the lifting speed of the telescopic rod assembly 3.

[0014] The telescopic pole assembly 3 includes multiple pole cylinders 30 that are sequentially sleeved from the outside to the inside. Specifically, the telescopic pole assembly 3 has a 3-10 level telescopic structure and can be adapted to the actual length to be extended. Two adjacent rod cylinders 30 are slidably connected by a guide slider 31, which is slidably connected to the outer wall of the inner rod cylinder 30. A guide pulley 32 is provided at the top of each rod cylinder 30, and a transition hole 33 is provided at the bottom of each rod cylinder 30. The telescopic control rope 4 passes through the guide pulley 32 at the top of the outermost rod cylinder 30, then through the transition hole 33 at the bottom of the innermost rod cylinder 30, and then winds along its outer wall to the second guide pulley 32 at the top. This process is repeated sequentially around all the rod cylinders 30 and then fixedly connected to the transition hole 33 at the bottom of the innermost rod cylinder 30. When the electric drum 2 drives the telescopic control rope 4 to wind, the multiple rod cylinders 30 located inside the outermost rod cylinder 30 rise together. When the electric drum 2 is controlled to rotate in the opposite direction, the telescopic control rope 4 is released in the opposite direction, and the multiple rod cylinders 30 located inside the outermost rod cylinder 30 fall together under the action of gravity, thus realizing the lifting and lowering control.

[0015] A combing assembly 5 is also provided on the top of the support base 1. The combing assembly 5 includes a combing bracket 50 fixed to the top of the support base 1 by fasteners, a lead screw motor 51 fixed to the top of the combing bracket 50 by bolts, a slide rail 52 fixed to the top of the combing bracket 50 by fasteners, a slider 53 powered to the output end of the lead screw motor 51, and a combing shaft 54 ​​rotatably mounted on the slider 53 by a pin. The slider 53 is slidably mounted on the slide rail 52. Driven by the lead screw motor 51, the slider 53 slides back and forth along the slide rail 52, and the telescopic control rope 4 passes through the combing shaft 54. A nut adapted to the lead screw of the lead screw motor 51 is provided on the slider 53. The lead screw motor 51 is the output shaft of the motor. When the lead screw motor 51 is energized and rotates, it can drive the slider 53 to slide on the slide rail 52. During the lifting operation, under the synchronous control of the controller, the lead screw motor 51 drives the slider 53 to move synchronously with the winding position of the telescopic control rope 4, ensuring the stability and orderliness of the combing.

[0016] An auxiliary support assembly 6 is also fixedly installed on the top of the support base 1. Four sets of auxiliary support assemblies 6 are arranged at intervals along the circumference of the telescopic rod assembly 3. The auxiliary support assembly 6 includes an auxiliary mounting base 60 fixedly installed on the top of the support base 1 by fasteners, an auxiliary drive motor 61 fixedly installed on the top of the auxiliary mounting base 60 by fasteners, a grooved wheel 62 fixedly installed on the output shaft of the auxiliary drive motor 61 by a coupling, and a tension rope 63 wound in the grooved wheel 62. One end of the tension rope 63 is set on the top of the telescopic rod assembly 3 through a connector 8, specifically connected to the top of the rod cylinder 30 located at the center of the telescopic rod assembly 3. A tension sensor 9 is set on the connector 8. One end of the tension rope 63 is connected to the tension sensor 9, and the other end of the tension sensor 9 is connected to the connector 8. The tension sensor 9 is used to measure the tension value when the tension rope 63 is tensioned. The controller determines the stability of the telescopic rod assembly 3 after extension based on the tension value of the tension sensor 9.

[0017] During the extension and retraction of the system, the auxiliary drive motor 61 is linked with the electric drum 2 to synchronize the rope release or retraction of the auxiliary support assembly 6 with that of the extension control rope 4. Alternatively, the rotation speed of the auxiliary drive motor 61 can be controlled based on the tension value measured by the tension sensor 9, which measures the tension of the tension rope 63 in real time. During rope release, if the tension value measured by the tension sensor 9 exceeds a preset value, the controller increases the speed of the auxiliary drive motor 61 to coordinate the rope release or retraction of the extension control rope 4; if the tension value measured by the tension sensor 9 is lower than the preset value, the controller decreases the speed of the auxiliary drive motor 61 to coordinate the rope release or retraction of the extension control rope 4. During rope retraction, if the tension value measured by the tension sensor 9 is lower than the preset value, the controller increases the speed of the auxiliary drive motor 61 to coordinate the rope release or retraction of the extension control rope 4.

[0018] The above embodiments are merely illustrative of the concept and implementation of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical solutions without substantial changes are still within the scope of protection.
