Abstract
Description
Technical Field
[0001] This utility model relates to the field of quantitative cable laying technology, specifically a quantitative cable laying device for high-voltage construction. Background Technology
[0002] High-voltage electrical engineering mainly includes: residential electricity, power electricity, commercial electricity, landscape lighting electricity, office electricity, etc. High-voltage electrical engineering in building construction is a crucial link that determines whether the project can pass the acceptance smoothly and be used in a long-term standardized manner. During the cable laying process, the cable is usually laid manually by hand. However, it is difficult to guarantee real-time quantitative laying during manual laying. Therefore, metering wheels are usually used for auxiliary measurement.
[0003] However, if the pressure of the measuring wheel is not properly adjusted, or if there is oil or dust on the surface of the cable, the friction between the measuring wheel and the cable will be insufficient, which will easily lead to slippage or free spin, causing serious inaccuracy in the counting of the measuring wheel. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a quantitative wire laying device for high-voltage construction.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A quantitative wire laying device for high-voltage power construction, comprising:
[0007] Cable reel;
[0008] A U-shaped frame is located on one side of the cable reel, and a guide wheel is provided inside the U-shaped frame for rotation.
[0009] A metering pulley is rotatably mounted within a U-shaped frame, and the metering pulley guides and measures the cable on the cable reel via a guide wheel.
[0010] A buffer sleeve is fitted inside the guide groove in the metering pulley, and a guide groove is provided on the outer circumferential surface of the buffer sleeve to laterally restrict the position of the cable.
[0011] A guide ring is symmetrically arranged on the inner sidewall of the guide groove of the metering pulley. The inner sidewall of the guide ring is inclined and forms an angle α with the inner sidewall of the metering pulley, where α is between 120° and 150°.
[0012] When the buffer sleeve deforms, it expands radially outward to the inclined surface of the guide ring. This inclined surface forces the buffer sleeve to be squeezed from both ends toward the middle, while the opening of the guide groove clamps the side wall of the cable.
[0013] Preferably, it also includes a U-shaped plate, which is evenly spaced around the middle of the metering pulley guide groove, and the U-shaped plate is parallel to the axis of the buffer sleeve. At the same time, the U-shaped plate is inserted into the corresponding fitting grooves on the inner side and two end faces of the buffer sleeve.
[0014] Preferably, the two side walls at the opening of the guide groove are provided with multiple sets of hemispherical protrusions at equal intervals along the circumference, and the protrusions are located close to the semi-circular surface of the cable away from the buffer sleeve.
[0015] Preferably, the arc-shaped bottom surface of the guide groove is uniformly provided with multiple sets of C-shaped ridges along the circumference, and the ridges are parallel to the axis of the buffer sleeve.
[0016] Preferably, the measuring pulley is rotatably disposed within a U-shaped frame, and two sets of guide wheels are rotatably disposed at the two ends of the U-shaped frame, with the measuring pulley located between the two sets of guide wheels. At the same time, the cable passes under the guide wheels and wraps around the measuring pulley in a Z-shape.
[0017] Preferably, the buffer sleeve is made of high-performance polyurethane elastomer.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] By coordinating the metering pulley, buffer sleeve, guide ring, U-shaped frame, and guide wheel, this device allows the cable to squeeze the buffer sleeve of the metering pulley under the limit of the guide wheel when quantitatively feeding the cable. This allows the buffer sleeve to form a lateral squeezing clamp on the cable under the guidance of the inclined surface of the guide ring, increasing the contact area and improving the frictional resistance. This enhances the stability of the synchronous movement of the cable and the metering pulley, effectively reducing the probability of slippage or free rotation between the metering pulley and the cable due to insufficient friction, and improving the counting accuracy of the metering pulley.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0029] Example
[0030] like Figures 1 to 6 As shown, a quantitative wire laying device for high-voltage construction includes:
[0031] Cable reel 3;
[0032] The U-shaped frame 4 is located on one side of the cable reel 3, and a guide wheel 41 is rotatably provided inside the U-shaped frame 4;
[0033] Measuring pulley 2 is rotatably mounted inside U-shaped frame 4. Measuring pulley 2 guides and measures the cable on cable reel 3 through guide wheel 41.
[0034] A buffer sleeve 22 is fitted into a guide groove in the metering pulley 2, and a guide groove 221 is provided on the outer peripheral surface of the buffer sleeve 22 to laterally restrict the position of the cable.
[0035] Guide ring 211 is symmetrically arranged on the inner side wall of the guide groove of metering pulley 2. The inner side wall of guide ring 211 is inclined and forms an angle α with the inner side wall of metering pulley 2, where α is between 120 degrees and 150 degrees.
[0036] When the buffer sleeve 22 deforms, it expands radially outward to the inclined surface of the guide ring 211. This inclined surface forces the buffer sleeve 22 to be squeezed from both ends toward the middle, while the opening of the guide groove 221 clamps the side wall of the cable.
[0037] Specifically, the cable reel 3 is rotatably mounted on the inner surface of the mounting frame 1 to reel in and unload the cable, while the U-shaped frame 4 is fixedly mounted on the inner side wall of the mounting frame 1, and the U-shaped frame 4 is higher than the top of the cable reel 3. The guide wheel 41 and the metering pulley 2, which are rotatably mounted inside the U-shaped frame 4, are both located on the cable reel path. When the cable is unloaded from the cable reel 3, the metering pulley 2 will rotate synchronously with the movement of the cable, so as to measure the length of the unloaded cable and guide the cable.
[0038] The metering pulley 2 consists of a side plate 21, a transmission rod 23, a buffer sleeve 22, and an encoder 24. The buffer sleeve 22 is fitted onto the middle of the transmission rod 23. Two side plates 21 are fitted onto both ends of the transmission rod 23 and abut against the end face of the buffer sleeve 22. A guide ring 211 is provided on the side of the side plate 21 opposite to the buffer sleeve 22. The outer diameter of the guide ring 211 is larger than the outer diameter of the buffer sleeve 22. The transmission rod 23 is rotatably mounted inside the U-shaped frame 4, while the encoder 24 is fixed to the outer wall of the U-shaped frame 4, and the rotation shaft of the encoder 24 is fixed to the transmission rod 23.
[0039] The inner surface of the mounting frame 1 is provided with a motor assembly 12 and a carrying plate 11. The carrying plate 11 is rotatable, and the cable reel 3 is placed and fixed on the surface of the carrying plate 11. The motor assembly 12 has a built-in electrically connected PLC module. The drive wheel of the output shaft of the motor assembly 12 meshes with the evenly spaced toothed grooves on the circumference of the carrying plate 11, so that the main motor can drive the carrying plate 11 and the cable reel 3 to rotate synchronously, reducing the difficulty of quantitative cable laying during high-voltage construction. The outer side of the U-shaped frame 4 is fixed with an encoder 24. The rotation shaft of the encoder 24 is fixed to the end face of the transmission rod 23 in the metering pulley 2. Then the encoder 24 can transmit the rotation data of the metering pulley 2 to the electrically connected PLC module in real time. When the rotation data reaches the preset value input by the worker in the PLC module, the PLC module can automatically shut down the motor assembly 12 to improve the accuracy of quantitative cable laying.
[0040] Meanwhile, with the assistance of the guide wheel 41, the cable passes over the metering pulley 2 in a Z-shape, which then squeezes the guide groove 221 of the buffer sleeve 22. The buffer sleeve 22 deforms radially under the force, and the deformed part of the buffer sleeve 22 is squeezed from both ends to the middle under the guidance of the inclined surface of the guide ring 211. This allows the two side walls at the opening of the guide groove 221 to press and clamp the side walls of the cable inside. That is, the axial cross section of the opening of the guide groove 221 changes from U-shaped to C-shaped, thereby increasing the pressing area and frictional resistance between the metering pulley 2 and the cable, reducing the probability of slippage or free rotation between them, and ensuring the accuracy of cable laying and metering.
[0041] It also includes a U-shaped plate 212, which is evenly spaced around the middle of the guide groove of the metering pulley 2. The U-shaped plate 212 is parallel to the axis of the buffer sleeve 22, and the U-shaped plate 212 is inserted into the corresponding fitting grooves on the inner side and two end faces of the buffer sleeve 22.
[0042] Specifically, the U-shaped plate 212 is circumferentially arranged on the transmission rod 23 in the metering pulley 2. The arrangement of the U-shaped plate 212 can divide and limit the inner wall of the buffer sleeve 22. Then, when the guide groove 221 on the outer wall of the buffer sleeve 22 is squeezed by the cable, the U-shaped plate 212 can limit the deformation direction of the squeezed part of the buffer sleeve 22, enhance the radial deformation effect of the buffer sleeve, and thus help enhance the pressure and clamping effect of the guide groove 221 on the cable.
[0043] The two side walls at the opening of the guide groove 221 are provided with multiple sets of hemispherical protrusions at equal intervals along the circumference, and the protrusions are located close to the semi-circular surface of the cable away from the buffer sleeve 22.
[0044] Specifically, the protrusions allow multiple tiny protrusions to form on the sidewall of the guide groove 221 opening in the circumferential direction, thereby enhancing the squeezing effect of the guide groove 221 opening against the two sides of the cable and increasing the frictional resistance between the buffer sleeve 22 and the cable.
[0045] The guide groove 221 has multiple sets of C-shaped ridges evenly arranged circumferentially on its arc-shaped bottom surface, and the ridges are parallel to the axis of the buffer sleeve 22.
[0046] Specifically, the textured structure at the bottom of the guide groove 221 can both help increase the frictional resistance of the contact surface when the cable is squeezed into the buffer sleeve 22 and help improve the deformation effect of the buffer sleeve 22.
[0047] The metering pulley 2 is rotatably mounted inside the U-shaped frame 4, and two sets of guide wheels 41 are rotatably mounted at both ends of the U-shaped frame 4. The metering pulley 2 is located between the two sets of guide wheels 41, and the cable passes under the guide wheels 41 and wraps around the metering pulley 2 in a Z-shape.
[0048] Specifically, through the cooperation of the guide wheel 41 and the metering pulley 2, the moving path of the cable when passing through the U-shaped frame 4 is in the shape of a zigzag, which can enhance the stability of the cable pressing the buffer sleeve 22 in the metering pulley 2 when moving, and reduce the probability of the cable and the metering pulley 2 spinning freely or slipping.
[0049] The buffer sleeve 22 is made of high-performance polyurethane elastomer.
[0050] Specifically, it can be made of cast polyurethane (CPU) or thermoplastic polyurethane (TPU), with a hardness between Shore A70 and A85. This range provides sufficient support and wear resistance while ensuring good elastic clamping effect.
[0051] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
