Description

Technical Field

[0001] The utility model relates to the technical field of positioning for power design, and particularly provides a multi-point positioning device for power design. Background Technique

[0002] Power design includes power engineering design and power equipment design. Power engineering design includes power generation, power transmission, power transformation, power distribution design, etc. Power equipment design includes the design of primary and secondary equipment such as switchgear, power transmission equipment, power distribution equipment, complete sets of equipment, and relay protection. In the process of power design, the laying of power lines is essential. When installing power lines with a large span, it is often necessary to install a multi-point positioning device for the line at certain intervals to improve the overall anti-interference ability of the line.

[0003] A multi-point positioning device for power design provided by the publication number "CN215580276U" adjusts the distance between each line by rotating the limit seat. The servo motor is started, and the rotating shaft rotates uniformly under the action of the reducer. The belt rotates accordingly. At this time, the belt drives the threaded rod to rotate, and the sliding seat moves linearly upward on the threaded rod, so that each cable rises to an appropriate height. The servo motor is turned off to complete the positioning of the circuit cable. The utility model can adjust the distance between each cable by using the multi-point positioning device and adjust the height of the cable at the same time.

[0004] However, the above technical solution and the existing technologies have the following defects:

[0005] First of all, although the multi-point positioning device for power design can complete the adjustment of the cable spacing by rotating the limit seat, the spacing cannot be adjusted after the cable is installed. Moreover, the upper positioning plate and the lower positioning plate in this device cannot be adjusted back and forth during use, and the cable fixing positions cannot be staggered. Secondly, when adjusting the height of the upper positioning plate and the lower positioning plate, this device can only be adjusted as a whole, and the height of a single set of upper positioning plate and lower positioning plate cannot be adjusted separately, and the adjustment range is limited, so the practicality needs to be improved. Content of the Utility Model

[0006] The purpose of the utility model is to provide a multi-point positioning device for power design to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution:

Inside the support frame, there is an adjustment component, and the adjustment component is used to adjust and position the multiple electric wires for power design in multiple directions. Inside the side support plates, there is a support component, and the support component is used to adjust the use height of the support frame, so as to make the use flexibility of this device better.

[0009] Preferably, the adjustment component includes a longitudinal support rod, a longitudinal adjustment sleeve, a vertical adjustment sleeve, a connecting suspension rod, a left clamp seat, a right clamp seat, a limit through groove, and an extension screw rod.

[0010] Preferably, a positioning nut is installed on the annular side surface of the extension screw rod. A fixing screw is installed at the middle position of the upper end surface of the longitudinal adjustment sleeve. A locking screw is installed at the middle position of the left end face of the vertical adjustment sleeve.

[0011] Preferably, the support component includes a lifting plate, a vertical lead screw, a worm, and a worm gear. A vertical lead screw is installed inside the side support plate. A worm gear is arranged on the lower side of the annular side surface of the vertical lead screw. A worm is meshed with the rear side of the annular side surface of the worm gear. Lifting plates are symmetrically arranged on the left and right end faces of the support frame.

[0012] Preferably, a vertical internal thread through hole is opened inside the lifting plate, and the vertical internal thread through hole is meshed with the vertical lead screw. A limit cavity is opened on the inner wall of the side support plate, and the limit cavity is matched with the lifting plate.

[0013] Preferably, a limit ring is arranged on the right side of the annular side surface of the worm. A hand turntable is arranged at the right end of the worm. A limit cover is installed on the right end face of the support base.

Anti-slip silicone sheets are adhered to both the inner wall of the left clamp seat and the inner wall of the right clamp seat. Both the left clamp seat and the right clamp seat are matched with the electric wires for power design.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. After the device clamps and fixes the wires used in electrical design through the left clamp seat and the right clamp seat, by loosening the fixing screws, the longitudinal adjusting sleeve can be displaced back and forth, thereby adjusting the front and back usage positions of the left clamp seat and the right clamp seat. By loosening the positioning nuts, the longitudinal struts can be moved left and right, thereby adjusting the left and right spacing between the longitudinal struts. By loosening, disassembling and assembling the locking screws, the vertical adjusting sleeve can be displaced slightly up and down, so that the staff can separately adjust the usage height of the left clamp seat and the right clamp seat according to requirements, thereby increasing the adjustment range of the device and making the applicable range of the device better.

[0017] 2. After the device is transferred to the required position at the electrical design construction site, by rotating the worm forward, the worm gear can drive the vertical lead screw to rotate in reverse, and the reverse rotating vertical lead screw will drive the support frame to move downward through the lifting plate. Similarly, when the worm is rotated in reverse, the lifting plate can drive the support frame to move upward, so that the staff can adjust the usage height of the support frame according to requirements. And because the worm and the worm gear have self-locking ability, the support frame will not fall back during use. At the same time, this structure does not require a separate external power supply during use, and the usability is good. Description of the Drawings

[0036] Working principle: When multi-point positioning of the wire 6 for electrical design is required, the staff first push the device to the required position at the electrical design construction site. At this time, step on the foot brake of the movable caster 2 for positioning to prevent the device from moving again. Then, rotate the worm 44 forward through the hand turntable 442, so that the worm 44 can drive the vertical lead screws 42 on the left and right to reverse synchronously through the worm wheels 45 on the left and right. The two reversed vertical lead screws 42 drive the support frame 5 to move downward through the lifting plate 41, and the support frame 5 will drive the adjustment component 7 to descend together. Similarly, when the worm 44 is reversed, the support frame 5 will drive the adjustment component 7 to rise, so that the staff can adjust the use height of the adjustment component 7 and the support frame 5 according to the needs. After adjusting to the required height, stop rotating the worm 44; Subsequently, the staff loosen the multiple fixing screws 711 respectively. At this time, the multiple longitudinal adjusting sleeves 72 can be displaced forward and backward respectively, and the adjusting sleeve will drive the left clamping seat 75 and the right clamping seat 76 to move forward and backward through the connecting suspension rod 74 and the vertical adjusting sleeve 73, so that the staff can adjust the forward and backward use positions of the left clamping seat 75 and the right clamping seat 76 according to the needs. After adjusting to the required position, tighten the multiple fixing screws 711 respectively to prevent the multiple longitudinal adjusting sleeves 72 from moving forward and backward again; When the multiple positioning nuts 79 are loosened respectively, the multiple longitudinal struts 71 can be moved left and right, so that the staff can adjust the distance between the multiple longitudinal struts 71 according to the needs. After the adjustment is completed, tighten the multiple positioning nuts 79 respectively, and the multiple longitudinal struts 71 can be positioned through the multiple extension screws 78; When the multiple locking screws 712 are loosened, disassembled and assembled respectively, the multiple vertical adjusting sleeves 73 can be displaced slightly up and down respectively, and the vertical adjusting sleeve 73 will drive the left clamping seat 75 and the right clamping seat 76 to move up and down together, so that the staff can adjust the use height of the left clamping seat 75 and the right clamping seat 76 according to the needs. After the adjustment is completed, install and fix the multiple locking screws 712 in the corresponding internal thread fixing holes 741 respectively to prevent the multiple vertical adjusting sleeves 73 from falling back and slipping; At this time, the staff can remove the right clamping seat 76 by loosening and disassembling the installation screws with the help of an external wrench. Then, lean the wire 6 for electrical design against the right end of the left clamping seat 75. Immediately afterwards, install and fix the right clamping seat 76 on the right end face of the left clamping seat 75 with the help of the installation screws, so that the left clamping seat 75 and the right clamping seat 76 can clamp and fix the wire 6 for electrical design. And in this process, only by placing multiple such devices at certain intervals at the electrical design construction site, multi-point support and positioning of the wire 6 for electrical design can be achieved, so as to ensure the overall anti-interference ability of the wire 6 for electrical design.
