Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, and in particular to a cable measuring device for power engineering construction. Background Technology

[0002] Electrical cables are a large category of electrical wire products used to transmit electricity and convert electromagnetic energy, and are widely used in various power systems. When measuring cables, a length counter is typically used to measure the cable length. The length counter uses a Hall effect switch to pick up the number of rotations of the guide roller of the measured material and adds the circumference of the guide roller itself to calculate the length.

[0003] In existing technologies, when measuring cables using a meter counter, a measuring wheel is used to hold the cable in place, and pulling the cable causes the measuring wheel to rotate. An encoder picks up the number of rotations of the measuring wheel, and the control box displays the cable length. However, in practical applications, when pulling the cable, the measuring wheel rotates, and after the cable has completely passed the measuring wheel, it often fails to stop immediately due to inertia, resulting in certain errors in the measurement data. Therefore, an improved cable measuring device for power engineering construction is proposed. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a cable measuring device for power engineering construction, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a cable measuring device for power engineering construction, including a base, a mounting frame fixedly connected to the base, a guide wheel rotatably connected to the mounting frame, a support wheel rotatably connected to the mounting frame, a support plate rotatably connected to the mounting frame, a measuring wheel rotatably connected to the end of the support plate, an encoder provided on the support plate, a control box provided on the base, and a tension spring provided between the mounting frame and the support plate;

[0007] A horizontal plate is fixedly connected to the support plate and disposed on one side of the measuring wheel. A movable plate is inserted into the horizontal plate, and a spring is disposed between the movable plate and the horizontal plate. A pawl is fixedly connected to one side of the movable plate, and a ratchet is fixedly connected to one side of the measuring wheel.

[0008] Preferably, in any of the above embodiments, the mounting bracket is disposed on one side of the base, and the guide wheels are in two sets and are respectively disposed at both ends of the mounting bracket.

[0009] Preferably, in any of the above embodiments, the support roller is positioned in the middle of the mounting frame, and limit plates are provided at both ends of the measuring roller.

[0010] The above technical solution employs the following: A base provides an installation platform for the upper structure. A mounting frame is installed on the base, providing a platform for components such as guide wheels and support wheels. Guide wheels guide the cable; two sets of guide wheels are positioned at both ends of the mounting frame, allowing the cable to pass smoothly between the measuring wheel and the support wheels. Support wheels support the cable from the bottom and cooperate with the measuring wheel for cable passage. A support plate is installed on the mounting frame, providing an installation platform for the measuring wheel. The support plate is rotatably connected to the mounting frame, allowing it to move the measuring wheel.

[0011] Preferably, in any of the above embodiments, a connecting plate is fixedly connected to the mounting bracket, and the tension spring is disposed between the connecting plate and the support plate.

[0012] Preferably, in any of the above solutions, the horizontal plate adopts an L-shaped structure, and an end plate is fixedly connected to the top of the movable plate.

[0013] The above technical solution employs the following: an encoder is used to pick up the number of rotations of the measuring wheel and transmit the information to the control box, which displays the cable length. A tension spring is used to tie the support plate, ensuring that the measuring wheel adheres to the support roller when no external force is applied, so that the measuring wheel presses against the cable during measurement. A horizontal plate is installed on the support plate, providing a mounting platform for the movable plate. The movable plate is inserted into the horizontal plate, allowing it to move under external force. An end plate is installed at the top of the movable plate, providing a mounting platform for the spring.

[0014] Preferably, the bottom surface of the movable plate is inclined, and a constraint rod is fixedly connected to the horizontal plate and inserted into the top end plate of the movable plate.

[0015] Preferably, in any of the above embodiments, the spring is disposed between the horizontal plate and the top end plate of the movable plate, and the spring is sleeved on the outside of the constraint rod on the horizontal plate.

[0016] The above technical solution works as follows: When the cable passes between the measuring wheel and the support wheel, the cable pushes the movable plate upward, which in turn moves the pawl upward, disengaging it from the ratchet and releasing the measuring wheel from its constraint. The cable can then be pulled to rotate the measuring wheel for measurement. When the cable has completely passed between the measuring wheel and the support wheel, the movable plate, under the influence of gravity and the spring, moves downward to its original position, causing the pawl to return to its original position. The pawl then locks the ratchet, thus locking the measuring wheel and preventing it from continuing to rotate due to inertia, which could affect the accuracy of the measurement results.

[0017] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0018] 1. This cable measuring device for power engineering construction utilizes a structure consisting of a horizontal plate, a movable plate, springs, pawls, and ratchet. During measurement, the cable passes through the guide wheel, and the support plate is moved, causing the measuring wheel to move and pass between the measuring wheel and the support wheel. Releasing the support plate causes the tension spring to pull the support plate, pressing the measuring wheel onto the cable. As the cable passes between the measuring wheel and the support wheel, it pushes the movable plate upwards, which in turn moves the pawl upwards, disengaging it from the ratchet and releasing the measuring wheel from its constraint. The cable can then be pulled to rotate the measuring wheel for measurement. When the cable has completely passed between the measuring wheel and the support wheel, the movable plate, under the influence of gravity and the spring, moves downwards to its original position, causing the pawl to return to its original position and lock the ratchet, thus locking the measuring wheel. This prevents the measuring wheel from continuing to rotate due to inertia, which could affect the accuracy of the measurement results, resulting in more precise measurements.

[0019] 2. In this cable measuring device for power engineering construction, a tension spring is used to tie the support plate, so that the measuring wheel is attached to the support wheel when there is no external force, so that the measuring wheel presses on the cable during measurement work. The bottom surface of the movable plate is inclined to facilitate the cable pushing the movable plate upward.

[0029] like Figures 1-4 As shown, this utility model includes a base 1, a mounting frame 2 fixedly connected to the base 1, a guide wheel 3 rotatably connected to the mounting frame 2, a support wheel 4 rotatably connected to the mounting frame 2, a support plate 5 rotatably connected to the mounting frame 2, a measuring wheel 6 rotatably connected to the end of the support plate 5, an encoder 7 provided on the support plate 5, a control box 8 provided on the base 1, and a tension spring 9 provided between the mounting frame 2 and the support plate 5.

[0030] A horizontal plate 10 is fixedly connected to the support plate 5 and is located on one side of the measuring wheel 6. A movable plate 11 is inserted into the horizontal plate 10. A spring 12 is provided between the movable plate 11 and the horizontal plate 10. A pawl 13 is fixedly connected to one side of the movable plate 11 and a ratchet 14 is fixedly connected to one side of the measuring wheel 6.

[0031] Example 1: The mounting frame 2 is located on one side of the base 1. Two sets of guide wheels 3 are respectively located at both ends of the mounting frame 2. Support wheels 4 are located in the middle of the mounting frame 2, and limit plates are provided at both ends of the measuring wheel 6. The base 1 provides a mounting platform for the upper structure. The mounting frame 2 is installed on the base 1, providing a mounting platform for components such as the guide wheels 3 and support wheels 4. The guide wheels 3 are used to guide the cable. Two sets of guide wheels 3 are located at both ends of the mounting frame 2, allowing the cable to pass smoothly between the measuring wheel 6 and the support wheels 4. The support wheels 4 support the cable from the bottom and cooperate with the measuring wheel 6 to allow the cable to pass through. A support plate 5 is installed on the mounting frame 2, providing a mounting platform for the measuring wheel 6. The support plate 5 is rotatably connected to the mounting frame 2, allowing it to drive the measuring wheel 6 to move.

[0032] Example 2: A connecting plate is fixedly connected to the mounting bracket 2, and a tension spring 9 is disposed between the connecting plate and the support plate 5. The horizontal plate 10 has an L-shaped structure, and an end plate is fixedly connected to the top of the movable plate 11. The encoder 7 is used to pick up the number of rotations of the measuring wheel 6 and transmit the information to the control box 8, which displays the length of the cable. The tension spring 9 is used to tie the support plate 5 so that the measuring wheel 6 is attached to the support wheel 4 when there is no external force, so that the measuring wheel 6 presses against the cable during measurement. The horizontal plate 10 is set on the support plate 5, and the horizontal plate 10 provides a mounting platform for the movable plate 11. The movable plate 11 is inserted into the horizontal plate 10, allowing it to move under the action of external force. An end plate is set at the top of the movable plate 11 to provide a mounting platform for the spring 12.

[0033] Example 3: The bottom surface of the movable plate 11 is inclined, and a constraint rod is fixedly connected to the horizontal plate 10 and inserted into the top end plate of the movable plate 11. A spring 12 is positioned between the horizontal plate 10 and the top end plate of the movable plate 11, and is sleeved on the outside of the constraint rod on the horizontal plate 10. When the cable passes between the measuring wheel 6 and the support wheel 4, the cable pushes the movable plate 11 upwards. This upward movement of the movable plate 11 then drives the pawl 13 upwards, disengaging it from the ratchet 14, thus releasing the constraint on the measuring wheel 6. The cable can then be pulled to rotate the measuring wheel 6 for measurement. When the cable has completely passed between the measuring wheel 6 and the support wheel 4, the movable plate 11 moves downwards and resets under the influence of gravity and the spring 12, subsequently resetting the pawl 13. The pawl 13 then locks the ratchet 14, locking the measuring wheel 6. This prevents the measuring wheel 6 from continuing to rotate due to inertia, thus ensuring the accuracy of the measurement results.

[0034] The working principle of this utility model is as follows:

[0035] S1. Pass the cable through the guide wheel 3 and move the support plate 5 to move the measuring wheel 6, so that the cable passes between the measuring wheel 6 and the support wheel 4. Release the support plate 5, and the tension spring 9 pulls the support plate 5 to move, causing the measuring wheel 6 to press on the cable;

[0036] S2. When the cable passes between the measuring wheel 6 and the support wheel 4, the cable pushes the movable plate 11 upward. The upward movement of the movable plate 11 then drives the pawl 13 upward, disengaging the pawl 13 from the ratchet 14, thus releasing the constraint on the measuring wheel 6. The cable can then be pulled to rotate the measuring wheel 6 for measurement. When the cable has completely passed between the measuring wheel 6 and the support wheel 4, the movable plate 11 moves downward and resets under the action of gravity and the spring 12, subsequently driving the pawl 13 to reset. The pawl 13 then locks the ratchet 14, thus locking the measuring wheel 6.

[0037] S3, encoder 7 is used to pick up the number of rotations of measuring wheel 6 and transmit the information to control box 8. Control box 8 displays the length of the cable.

[0038] Compared with the prior art, the present invention has the following advantages:

[0039] 1. This cable measuring device for power engineering construction, through the arrangement of a horizontal plate 10, a movable plate 11, a spring 12, a pawl 13, and a ratchet 14, allows the cable to pass through the guide wheel 3 during measurement. The support plate 5 is then moved, causing the measuring wheel 6 to move and pass between the measuring wheel 6 and the support roller 4. Releasing the support plate 5 causes the tension spring 9 to pull the support plate 5, pressing the measuring wheel 6 onto the cable. As the cable passes between the measuring wheel 6 and the support roller 4, the cable pushes the movable plate 11 upwards, which in turn moves the pawl 13 upwards. The pawl 13 disengages from the ratchet 14, releasing the measuring wheel 6 from its constraint. The cable can then be pulled to rotate the measuring wheel 6 for measurement. When the cable passes completely between the measuring wheel 6 and the support wheel 4, the movable plate 11 moves down and resets under the action of gravity and the spring 12, which in turn drives the pawl 13 to reset. The pawl 13 locks the ratchet 14, thus locking the measuring wheel 6. This prevents the measuring wheel 6 from continuing to rotate under inertia and affecting the accuracy of the measurement results, making the measurement results more accurate.

[0040] 2. In this cable measuring device for power engineering construction, the tension spring 9 is used to tie the support plate 5, so that the measuring wheel 6 is attached to the support wheel 4 when there is no external force, so that the measuring wheel 6 presses on the cable during the measurement work. The bottom surface of the movable plate 11 is inclined, which facilitates the cable to push the movable plate 11 to move upward.
