Description

Technical Field

[0001] This utility model relates to the field of cable engineering technology, and in particular to an auxiliary device for cable engineering quantity statistics. Background Technology

[0002] Accurately calculating the length of cables used is a fundamental and crucial task in cable laying, warehousing management, and project settlement.

[0003] Currently, the length measurement of coiled or stacked cables mainly relies on manual operation. Workers measure in sections using tape measures or spread the cables out on the ground for marking and measurement.

[0004] Manual measurement requires a large amount of manpower to drag and arrange the cables, which is time-consuming and labor-intensive, resulting in low work efficiency. In addition, it is difficult to keep the cable perfectly straight during the measurement process. Any bend or slack will introduce measurement errors, making it difficult to guarantee the accuracy of the measurement results.

[0005] To improve efficiency, handheld or simple rolling measuring wheels have emerged in the industry. However, during measurement, operators need to manually press the measuring wheel tightly against the cable surface. Instability in the clamping force can cause the measuring wheel to slip or bounce between the measuring wheel and the cable surface. At the same time, for cables of different diameters, there is a lack of effective clamping and guiding mechanisms, and the cable will deviate laterally when passing through. These factors directly affect the accuracy and reliability of measurement.

[0006] Therefore, this utility model proposes an auxiliary device for cable engineering quantity statistics to address the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems in the existing technology of cable quantity statistics, such as low efficiency due to reliance on manual operation, inaccurate measurement results, and low measurement accuracy due to the inability of simple measuring devices to effectively clamp the cable and apply constant pressure, this utility model aims to provide a cable quantity statistics auxiliary device with an improved structure that can effectively solve the above problems.

[0008] This utility model provides an auxiliary device for cable engineering quantity statistics, including a base and a clamping and positioning device and a pre-tightening mechanism disposed on the base; the clamping and positioning device includes a support plate, a turntable, a gear, a support rod, a clamping block, and a limiting block; the pre-tightening mechanism includes a moving column, a hollow column, a piston, a support block, a roller, and a cylinder; the support plate is fixed to the base, the gear drives the turntable to rotate, the outer wall of the support rod is slidably connected to the arc-shaped groove on the surface of the turntable and the guide groove on the surface of the support plate, the support rod is fixedly connected to the clamping block, and the limiting block is connected to the clamping block and slides in the limiting groove on the surface of the support plate; simultaneously, the cylinder drives the moving column slidably connected to the base, the piston slides in the hollow column fixedly connected to the moving column and is subjected to pre-tightening force by an elastic component, and the roller is rotatably connected to the support block fixedly connected to the piston.

[0009] Preferably, the gear is meshed with the outer periphery of the turntable.

[0010] Preferably, the right side of the limiting block is fixedly connected to the left side of the clamping block.

[0011] Preferably, the right end of the support rod is fixed to the side of the clamping blocks that are far apart from each other.

[0015] Preferably, the center of the surface of the roller is rotatably connected to the right side of the support block.

[0016] Preferably, a recording component for recording the number of rotations of the roller is installed inside the support block.

[0017] This utility model has the following beneficial effects: 1. This utility model, by setting up a linkage mechanism consisting of a turntable, an arc groove, a support rod, and clamping blocks working together, enables a single rotation drive to be converted into a synchronous centripetal clamping motion of multiple clamping blocks. This solves the problems of cumbersome operation, low efficiency, and inaccurate positioning caused by the inability to automatically adapt to different wire diameters when manually aligning and clamping cables in the prior art. It realizes rapid, automatic centering and stable clamping of cables of different wire diameters.

[0018] 2.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example: Please refer to Figures 1 to 4 This utility model provides a cable engineering quantity statistics auxiliary device, including a base 1, which serves as the installation platform for the entire device. The base 1 is equipped with a clamping and positioning device for clamping cables and a pre-tightening mechanism 2 for measuring cable length. The clamping and positioning device includes a support plate 3 fixedly connected to the top of the base 1. The support plate 3 provides installation and guidance references for other components of the clamping and positioning device.

[0023] The clamping and positioning device also includes a turntable 6 and a gear 8 that drives the turntable 6 to rotate. The turntable 6 is rotatably located at the far left end of the base 1. The gear 8 is meshed with the outer periphery of the turntable 6. The gear 8 is driven to rotate by an external drive source, thereby driving the turntable 6 to rotate. The surface of the support plate 3 is provided with a guide groove 4, and the surface of the turntable 6 is provided with an arc groove 7.

[0024] The clamping and positioning device also includes a support rod 9, the middle of the outer wall of the support rod 9 is slidably connected to the guide groove 4, the left end of the outer wall of the support rod 9 is slidably connected to the arc groove 7, and the clamping and positioning device also includes a clamping block 10, the right end of the support rod 9 is fixed on the side of the clamping block 10 that is far away from each other, so that the support rod 9 is driven to slide in the guide groove 4 by the rotation of the turntable 6, and the clamping block 10 is moved.

[0025] The clamping and positioning device also includes a limiting block 11. The right side of the limiting block 11 is fixedly connected to the left side of the clamping block 10. The surface of the support plate 3 is also provided with a limiting groove 5 for the limiting block 11 to slide. The limiting groove 5 and the guide groove 4 together constrain the clamping block 10 to perform synchronous centripetal or centrifugal movements.

[0026] like Figure 1 and Figure 3 and Figure 4 As shown, the pre-tightening mechanism 2 includes a movable column 201, the bottom surface of which is slidably connected to the front and rear sides of the top of the base 1. The pre-tightening mechanism 2 also includes a cylinder 206 mounted on the bottom of the movable column 201 on a side away from each other. The cylinder 206 drives the movable column 201 to slide freely on the top of the base 1. The top of the movable column 201 is fixedly connected to the bottom of the hollow column 202, allowing the hollow column 202 to slide synchronously with the movable column 201. The inner wall of the hollow column 202 is slidably connected to the outer wall of the piston 203. The side of the piston 203 that is away from each other is connected to the hollow column 202. An elastic component is provided between the inner walls. The elastic component continuously pushes the piston 203 to provide a preload. The adjacent side of the piston 203 is fixedly connected to the opposite side of the support block 204. The center of the surface of the roller 205 is rotatably connected to the right side of the support block 204. A recording component for recording the number of rotations of the roller 205 is installed inside the support block 204. Driven by the cylinder 206, the roller 205 approaches and adheres to the cable from the front and rear sides. Under the preload provided by the elastic component, the roller 205 rotates with the movement of the cable, and the length is measured by the recording component.

[0027] Please refer to Figure 1 , Figure 2 and Figure 3The bottom of the support plate 3 is fixedly connected to the top leftmost end of the base 1. The support plate 3 is provided with a guide groove 4 and a limiting groove 5. The guide groove 4 and the limiting groove 5 provide a precise sliding track for the moving parts of the clamping and positioning device. The turntable 6 is rotatably set at the left front end of the base 1. The surface of the turntable 6 is provided with an arc groove 7. The gear 8 meshes with the outer periphery of the turntable 6 and is driven to rotate by an external motor, thereby providing rotational power for the turntable 6.

[0028] The support rod 9 serves as a transmission link. The middle of the outer wall of the support rod 9 is slidably connected to the guide groove 4 on the surface of the support plate 3. Simultaneously, the left end of the outer wall of the support rod 9 is slidably connected to the arc-shaped groove 7 on the surface of the turntable 6. The right end of the support rod 9 is fixed to the side of the clamping block 10 that is far from it. The clamping block 10 is a clamping component that directly contacts the cable. To further constrain the movement trajectory of the clamping block 10, a limiting block 11 is fixedly connected to the left side of the clamping block 10. The outer wall of the limiting block 11 is slidably connected to the limiting groove 5 on the surface of the support plate 3. When the external motor drives the gear 8 to rotate, the gear 8 drives... Turntable 6 rotates synchronously. Due to its non-circular geometric contour, the arc groove 7 on turntable 6 pushes the support rod 9 sliding in the groove, forcing the support rod 9 to reciprocate linearly along the guide groove 4 on the support plate 3. Since the support rod 9 is fixedly connected to the clamping block 10, the clamping block 10 moves synchronously with the support rod 9. Under the cooperation of the limiting block 11 and the limiting groove 5, the movement of the clamping block 10 is precisely limited to the preset radial path, ensuring that multiple clamping blocks 10 can always remain synchronous during the movement, thereby realizing stable centripetal clamping or centrifugal release of the cable from different directions.

[0029] Specifically, in order to achieve precise driving of the clamping and positioning device, a stable transmission connection is formed between the gear 8 and the turntable 6. The outer teeth of the gear 8 mesh with the gear ring integrally formed on the outer circumference of the turntable 6. When the external drive source drives the gear 8 to rotate, the power can be transmitted to the turntable 6 without slippage, ensuring that the rotation angle of the turntable 6 corresponds precisely to the output of the drive source, and providing a stable and reliable power input for the subsequent linkage of the entire clamping and positioning device.

[0030] To ensure the stability and accuracy of the movement of the clamping block 10, a robust assembly structure is formed between the support rod 9, the clamping block 10, and the limiting block 11. The right side of the limiting block 11 is fixedly connected to the left side of the clamping block 10 by welding or bolting, while the right end of the support rod 9 is also fixed to the side of the clamping block 10 that is far away from it by welding or bolting. This allows the driving force transmitted by the support rod 9 to act directly on the clamping block 10, and the guiding constraint force of the limiting block 11 sliding in the limiting groove 5 can also be directly applied to the clamping block 10. This ensures the stability of the clamping block 10's posture during reciprocating motion, preventing deflection or wobbling.

[0031] To drive the measuring component, a cylinder 206 is installed at the bottom of the moving column 201. The cylinder body of the cylinder 206 is fixed to the moving column 201, and the extended end abuts against or connects to a fixed stop block provided on the base 1. When the cylinder 206 works, it pushes the moving column 201 in the opposite direction. The bottom of the moving column 201 forms a sliding connection with the top of the base 1. A linear guide rail is provided on the top of the base 1, and a slider is correspondingly provided on the bottom of the moving column 201. The slider cooperates with the linear guide rail, so that the moving column 201 can only slide smoothly along a preset straight line direction.

[0032] In order to establish a continuous and stable preload pressure between the roller 205 and the cable, the adjacent side of the piston 203 is fixedly connected to the opposite side of the support block 204. The elastic component is preferably a compression spring, which is housed in the inner cavity of the hollow column 202. The two ends of the compression spring abut against the opposite end face of the piston 203 and the bottom end of the inner wall of the hollow column 202, respectively. This arrangement ensures that the elastic component is always in a pre-compressed state, thereby generating a continuous outward thrust on the piston 203, and transmitting this thrust to the support block 204 and the roller 205 through the piston 203.

[0033] To achieve accurate length measurement, the center of the surface of the roller 205 is rotatably connected to the right side of the support block 204 via a rolling bearing, ensuring that the roller 205 can rotate freely with extremely low frictional resistance. The support block 204 is designed as a hollow cavity structure, and the recording component is preferably a high-precision rotary encoder. The high-precision rotary encoder is installed and fixed in the internal cavity of the support block 204, and the rotation shaft of the high-precision rotary encoder is coaxially and fixedly connected to the rotation shaft of the roller 205, so that any rotation of the roller 205 can be detected and converted into a digital pulse signal in real time and accurately by the high-precision rotary encoder.

[0034] Working principle: When it is necessary to measure the cable length, the cable is first passed through the central channel formed by the clamping block 10. Then, the clamping and positioning device is activated, and the external drive source drives the gear 8 to rotate. Since the gear 8 is meshed with the outer periphery of the turntable 6, the turntable 6 rotates synchronously. The rotation of the turntable 6 causes the arc groove 7 on the surface to push the support rod 9 which is slidably connected in the groove. Since the support rod 9 is also slidably connected in the guide groove 4 on the surface of the support plate 3, the movement of the support rod 9 is constrained to be linear displacement along the path of the guide groove 4. Since the support rod 9 is fixedly connected to the clamping block 10, the clamping block 10 moves synchronously with the support rod 9. At the same time, the limiting block 11, which is fixedly connected to the clamping block 10, slides in the limiting groove 5 of the support plate 3, further ensuring that the clamping blocks 10 can only move closer to each other or further away from each other, realizing automatic centering and four-way stable clamping of the cable, and solving the problem of inaccurate manual alignment. After the cable is clamped and positioned, the cylinder 206 of the pre-tightening mechanism 2 is activated. The cylinder 206 pushes the moving column 201 to slide on the top of the base 1. The measuring assembly, consisting of the hollow column 202, piston 203, support block 204, and roller 205 fixedly connected to the moving column 201, moves closer to the cable. When the roller 205 contacts the cable surface, the elastic component inside the hollow column 202 begins to apply a continuous thrust to the piston 203. This thrust is transmitted to the roller 205 through the support block 204 fixedly connected to the piston 203, ensuring that the roller 205 is always in close contact with the cable surface, achieving a pre-tightening effect to prevent slippage during measurement. When the cable passes through the device under external traction, the roller 205 rotates with the movement of the cable. The recording component installed inside the support block 204 records the number of rotations of the roller 205 in real time and calculates the length of the cable based on the preset circumference, thereby efficiently and accurately completing the engineering quantity statistics.
