Description

Technical Field

[0001] The utility model relates to the technical field of cable measuring tools, in particular to a simple tool for measuring the length of a cable. Background Technique

[0002] In the practical use of cables, as the service time of the cable increases, the length of the cable is consumed during use, and at the same time, the length spray code on the cable is worn and lost. During use, it is very difficult to master the actual length of the cable, which is a problem for cable management. Therefore, a rangefinder is needed to measure the distance of mining cables. However, some existing rangefinders are not convenient to move on the outer surface of mining cables, and the rangefinder is not convenient to be fixed on the outer surface of the cable, and it is not convenient to disassemble and install. In order to assist the measurement, a limit structure is generally used to assist the measurement of the rangefinder.

[0003] For example, a portable cable length electronic measuring tool with the publication number CN217953389U includes a mounting plate, a rangefinder, a spring locking device, a clamping wheel, a mining cable and a taking-out device. Two mounting grooves are opened on one side of the mounting plate. A spring locking device and a taking-out device are arranged inside the two mounting grooves. Sliding grooves are opened on both sides of the inner wall of each mounting groove. A clamping wheel is arranged on one side of each mounting groove. A mining cable is arranged between the two clamping wheels. A rangefinder is arranged on one side of the mounting plate, and one side of the rangefinder is fixedly connected to one side of the mounting plate. In the utility model, by setting the mounting plate, the clamping wheel and the measuring wheel, the mounting plate plays a role in mounting the two clamping wheels. One side of the clamping wheel is rotatably connected to the side surface of the sliding block, and the clamping wheel can slide on the outer surface of the mining cable.

[0004] The above cable measuring tool combines a clamping wheel and a measuring instrument, which is convenient to slide on the outer surface of the cable during the process of clamping the cable, increasing the measurement convenience. However, the whole sliding measurement process requires the measurer to hold and slide the operation by hand, especially for the measurement of vertical or inclined cables, which is very inconvenient. Therefore, we propose a simple tool for measuring the length of a cable. Content of the Utility Model

[0005] This part of the content of the present application is used to introduce the concept briefly, and these concepts will be described in detail in the following detailed implementation part. This part of the content of the present application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0006] The purpose of the utility model is to provide a simple tool for measuring the length of a cable to solve the problems raised in the above background technique.

One end of the telescopic frame is connected to a magnetic pulley, and scale grooves are distributed on the outer wall of the magnetic pulley. A motor is connected to one side of the axis of the magnetic pulley. A rangefinder is provided on one side of the middle of the cylindrical cavity.

[0008] Further, the telescopic frames and the magnetic pulley are annularly distributed along the inner wall around the inner cavity frame, and the scale grooves are annularly formed along the outer wall around the magnetic pulley.

[0009] Further, the telescopic frames are elastically telescoped and matched with the inner wall around the inner cavity frame through the sliders and springs.

A rotating shaft is connected to the other side of the frame body, and an equipment frame is fixed on the top surface of the frame body.

[0011] Further, the frame bodies are symmetrically distributed up and down through the rotating shaft, and the frame bodies are connected and fixed through the buckle frame and the bolts.

[0012] Further, the equipment frame includes a frame box, and an MCU main control chip is provided inside the frame box. A receiver module is provided on one side of the MCU main control chip.

It cooperates with the springs and sliders to maintain elastic telescopic adjustment. During the measurement process, there is no need for manual holding and sliding. Only by relying on wireless means to cooperate with the equipment frame to operate the motor and drive the magnetic pulley to clamp and drive along the cable, this tool can be placed and automatically slide and measure in cooperation with the rangefinder without manual holding throughout the process, providing convenience.

[0016] This cable measuring tool adopts a cylindrical frame design, which can be rotated and unfolded by means of a rotating shaft. Then, it clamps and limits the outside of the cable to be measured, and is connected and fixed by means of a buckle frame and bolts, providing stability for the subsequent measurement process and preventing the equipment from detaching and being damaged.

[0017] This measuring tool can receive the radio wave control signal generated by the operation of the remote control through the receiver module installed in the frame box, convert it into a digital signal, and then transmit the digital signal to the MCU main control chip. The MCU main control chip decodes it to form an instruction to cooperate with the connected motor control module to regulate the motor, maintaining the controllability of the sliding during the automatic measurement process.

[0027] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0028] The present utility model provides a tool for simply measuring the length of a cable as Figures 1-4 shown, which includes a cylindrical frame 1. A measurement cavity 2 is arranged inside the cylindrical frame 1, and an equipment frame 3 is connected to the top end of the cylindrical frame 1. The cylindrical frame 1 includes a frame body 101, and a buckle frame 102 is connected to one side of the frame body 101. Bolts 103 are distributed at both ends of the buckle frame 102. A rotating shaft 104 is connected to the other side of the frame body 101, and the equipment frame 3 is fixed on the top surface of the frame body 101;

[0029] To assist the stable use of the overall tool during the cable measurement process, as Figure 1 shown, this cable measurement tool is designed with a cylindrical frame body 101, which can be rotated and unfolded by cooperating with the rotating shaft 104, and then the outside of the cable to be measured is clamped and limited. It is connected and fixed by cooperating with the buckle frame 102 and the bolts 103 to provide stability for the subsequent measurement process and prevent the equipment from detaching and being damaged.

[0030] As Figures 2-3 shown, the measurement cavity 2 includes a cylindrical cavity 201, and an inner cavity frame 202 is connected to the inner wall of the cylindrical cavity 201. Telescopic frames 203 are distributed around the inner wall of the inner cavity frame 202. Sliders 204 are connected to the outer walls on both sides of the telescopic frames 203. The telescopic frames 203 and the inner wall of the inner cavity frame 202 form an elastic structure through springs 205. One end of the telescopic frame 203 is connected to a magnetic pulley 206, and groove lines 207 are distributed on the outer wall of the magnetic pulley 206. A motor 208 is connected to one side of the axis of the magnetic pulley 206. A rangefinder 209 is arranged on one side of the middle end of the cylindrical cavity 201;

[0031] To provide convenience for the cable measurement process, as Figures 2-3As shown in the figure, this cable measurement tool can maintain stable clamping around the outer wall of the cable through the magnetic pulleys 206 distributed on the inner walls around the cylinder cavity 201. It cooperates with the spring 205 and the slider 204 to maintain elastic telescopic adjustment. During the measurement process, there is no need for manual hand-held sliding. Only by relying on wireless means to cooperate with the equipment rack 3 to operate the motor 208, driving the magnetic pulleys 206 to drive along the cable clamping, this tool can be automatically slid and measured after being placed, without the need for manual hand-held use throughout the process, providing convenience.

[0032] As Figure 4 shown in the figure, the equipment rack 3 includes a rack box 301, and an MCU main control chip 302 is arranged inside the rack box 301. A receiver module 303 is arranged on one side of the MCU main control chip 302, and a motor control module 304 is arranged on one side of the receiver module 303, and the motor control module 304 is electrically connected to the motor 208;

[0033] Finally, in order to maintain stable control during the sliding process, as Figure 4 shown in the figure, this measurement tool can receive the radio wave control signal generated by the remote control operation through the receiver module 303 carried in the rack box 301, convert it into a digital signal, then transmit the digital signal to the MCU main control chip 302, and then the MCU main control chip 302 decodes it to form an instruction to cooperate with the connected motor control module 304 to control the motor 208, maintaining the controllability of the sliding during the automatic measurement process.

[0034] In summary, when this cable measurement tool is used for measurement, first unfold the frame body 101, buckle the outer wall of the cable, then rotate and buckle the unfolded frame body 101 along the rotating shaft 104, and then tighten the bolt 103 to fix the buckle frame 102. After the placement is completed, the internally distributed magnetic pulleys 206 are gradually pressed tightly with the telescopic frame 203 through the spring 205 to maintain stable synchronous clamping around the cable. Subsequently, the operator can control it through the remote control, emit a radio wave signal, receive the radio wave control signal generated by the remote control operation through the receiver module 303 carried in the rack box 301, convert it into a digital signal, then transmit the digital signal to the MCU main control chip 302, and then the MCU main control chip 302 decodes it to form an instruction to cooperate with the connected motor control module 304 to control the motor 208. Subsequently, the motor 208 drives the connected magnetic pulleys 206 to drive synchronously, enabling the overall device to slide and measure along the cable, causing the magnetic blocks of the magnetic pulleys 206 to generate voltage high and low signals with the Hall element inside the distance measuring instrument 209, and measuring the cable length by calculating the circumference of the measuring wheel and the frequency of the high and low levels, thus completing the measurement process.
