Description

Technical Field

[0001] This invention relates to the field of power construction technology, specifically to a cable stripping and polishing device for construction sites. Background Technology

[0002] Cable stripping and polishing are crucial steps in the construction, operation, and maintenance of power cables. When stripping cables, select appropriate tools should be used to ensure a smooth process without damaging the wire core. Special care must be taken when the insulation layer needs to be retained. Cable polishing removes burrs: Burrs may remain at the cable ends after stripping; polishing removes these burrs, improving the cable's conductivity and safety. It also smooths the surface: Polishing makes the cable end surface smoother, facilitating subsequent connections and installation. Improved contact quality: Polished cable ends make a tighter contact with connectors or equipment, improving contact quality and reducing contact resistance and heat generation.

[0003] However, the existing peeling and polishing are done separately, and both are done using sandpaper or sanding belts, which is labor-intensive, inefficient, and produces poor polishing results. Summary of the Invention

[0004] The purpose of this invention is to solve the above problems and provide a cable stripping and polishing device for construction sites, which can realize the simultaneous stripping and polishing of cables, improve efficiency, and ensure polishing effect.

[0005] The technical solution adopted by this invention to solve its technical problem is: A cable stripping and polishing device for construction sites includes an inner ring, an outer ring, and a rotating ring disposed between the inner ring and the outer ring, which are supported on and move on the cable. The rotating ring is provided with a stripping mechanism and a polishing mechanism. The stripping mechanism includes mounting plates symmetrically arranged around the cable, a first guide rod symmetrically arranged between the two mounting plates, and a moving block symmetrically arranged on the first guide rod and moving on the first guide rod. A cutter is provided on the left moving block, and the cutter is inclined backward from bottom to top. The grinding mechanism includes a lifting plate mounted on the rotating ring and moving up and down on the rotating ring, and a grinding belt mounted on the lifting plate and running on the lifting plate.

[0006] Furthermore, the inner ring is provided with wheels that travel on the cable.

[0007] Furthermore, a support wheel is provided in the middle of the right-side movable block, and support wheels are symmetrically provided on the inner side of the left-side movable block.

[0008] Furthermore, a first compression spring is provided between the right-side moving block and the corresponding mounting plate; The mounting plate on the left is provided with a first clamping screw. The first clamping screw passes through the mounting plate on the left and is threadedly connected to the mounting plate on the left. One end of the first clamping screw contacts the moving block on the left.

[0009] Furthermore, the movable block on the left is provided with a mounting groove, the bottom of which slopes backward from bottom to top, the cutter is disposed in the mounting groove, and a pressure block for fixing the cutter is provided in the mounting groove.

[0010] Furthermore, the rotating ring is provided with a second guide rod, the lifting plate is provided with a slider that cooperates with the second guide rod, and the second guide rod is provided with a second compression spring that pushes the lifting plate upward.

[0011] Furthermore, the lower end of the lifting plate is provided with a groove.

[0012] Furthermore, the lifting plate is provided with pulleys at both ends that cooperate with the grinding belt, and a motor is provided on the rotating ring. The output shaft of the motor is connected to the rotating shaft of one end of the pulley through a connecting mechanism.

[0013] Furthermore, the connecting mechanism includes a first connecting rod, a second connecting rod, a first belt, and a second belt. The first connecting rod and the second connecting rod are hinged together, and a rotatable pin is provided at the hinge point. The end of the first connecting rod away from the second connecting rod is rotatably connected to the motor output shaft, and the end of the second connecting rod away from the first connecting rod is rotatably connected to the shaft of the pulley. The shaft of the pulley is connected to the motor output shaft through the first belt and the second belt.

[0014] Furthermore, a handle is provided on the outer cylindrical surface of the outer ring.

[0015] The beneficial effects of this invention are: 1. The present invention includes an inner ring, an outer ring, and a rotating ring disposed between the inner ring and the outer ring, which are supported on and move on the cable. The rotating ring is provided with a stripping mechanism and a polishing mechanism. The inner ring is fitted onto the cable, and then the rotating ring rotates. The stripping mechanism rotates with the rotating ring to strip the cable, while the polishing mechanism polishes the stripped wire core. This allows the cable stripping and polishing to be carried out simultaneously, improving work efficiency.

[0016] 2. The stripping mechanism of this invention includes mounting plates symmetrically arranged around the cable, a first guide rod symmetrically arranged between the two mounting plates, and a moving block symmetrically arranged on the first guide rod and moving on the first guide rod. A cutter is provided on the left-side moving block, and the cutter is inclined backward from bottom to top. After the inner ring is placed on the cable, the rotating ring rotates. In the initial state, the cutter contacts the end of the cable rubber layer. The cutter rotates and cuts off the cable rubber layer as the rotating ring rotates. Since the cutter is inclined, a force is generated along the cable direction when rotating and cutting off the cable rubber layer, thereby causing the inner ring to move along the cable to complete the cable stripping work. It does not require a separate motor to drive the inner ring to move along the cable, which reduces costs.

[0017] 3. The grinding mechanism in this invention includes a lifting plate that is mounted on the rotating ring and moves up and down on the rotating ring, and a grinding belt that is mounted on the lifting plate and moves on the lifting plate. When the stripping mechanism peels off the rubber layer of the cable, the grinding belt grinds the cable core accordingly. In conjunction with the rotation of the rotating ring, the grinding belt has a good grinding effect on the core. Attached Figure Description

Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0022] like Figure 1 As shown, a cable stripping and polishing device for construction sites includes an inner ring 1, an outer ring 2, and a rotating ring 3 positioned between the inner ring 1 and the outer ring 2, all supported on and moving along the cable. The rear ends of the inner ring 1 and the outer ring 2 are connected as a single unit by a connecting rod. The rotating ring 3 is supported on the inner ring 1 by a slewing bearing and rotates on the inner ring 1. A rack is provided on the outer cylindrical surface of the rotating ring 3. A motor is provided on the outer ring 2, and a gear meshing with the rack is provided on the motor output. When the motor is running, the rotating ring 3 rotates under the action of the rack and gear. This is existing technology and will not be described in detail here. The rotating ring 3 is equipped with a stripping mechanism and a polishing mechanism. The inner ring 1 is fitted onto the cable, and then the rotating ring rotates. The stripping mechanism rotates with the rotating ring to strip the cable, while the polishing mechanism polishes the stripped wire core. This allows for simultaneous cable stripping and polishing, improving work efficiency.

[0023] like Figure 2 and Figure 4 As shown, the stripping mechanism includes mounting plates 4 symmetrically arranged around the cable, first guide rods 5 symmetrically arranged between the two mounting plates 4, and moving blocks 6 symmetrically arranged on the first guide rods 5 and moving on the first guide rods. The mounting plates 4 are fixed to the rotating ring 3. The two ends of the first guide rods 5 are respectively fixedly connected to the corresponding mounting plates 4. A cutter 7 is provided on the left moving block 6. The cutter 7 is inclined from bottom to top and backward. After the inner ring 1 is put on the cable, the rotating ring 3 rotates. In the initial state, the cutter 7 contacts the end of the cable rubber layer. The cutter 7 rotates and cuts off the cable rubber layer as the rotating ring 3 rotates. Since the cutter 7 is inclined, when it rotates and cuts off the cable rubber layer, it generates a force along the cable direction, thereby causing the inner ring 1 to move along the cable and complete the cable stripping work. It does not require a separate motor to drive the inner ring 1 to move along the cable, which is low cost.

[0024] like Figure 3 and Figure 4As shown, the polishing mechanism includes a lifting plate 8 that is mounted on the rotating ring 3 and moves up and down on the rotating ring 3, and a polishing belt 9 that is mounted on the lifting plate 8 and runs on the lifting plate 8. When the stripping mechanism peels off the rubber layer of the cable, the polishing belt 9 polishes the cable core accordingly. In conjunction with the rotation of the rotating ring 3, the polishing belt 9 has a good polishing effect on the core.

[0025] like Figure 2 As shown, the inner ring 1 is provided with a traveling wheel 10 that travels on the cable. The outer cylindrical surface of the traveling wheel 10 is provided with a rubber layer to increase the friction between it and the cable and prevent the inner ring from rotating on the cable.

[0026] like Figure 5 As shown, a support wheel 11 is provided in the middle of the right-side movable block 6, and a support wheel 11 is symmetrically provided on the inner side of the left-side movable block 6. The support wheel 11 is supported on the cable.

[0027] like Figures 5 to 7 As shown, a first compression spring 12 is provided between the right movable block 6 and the corresponding mounting plate 4; a first clamping screw 13 is provided on the left mounting plate 4. The first clamping screw 13 passes through the left mounting plate 4 and is threadedly connected to the left mounting plate 4. One end of the inner side of the first clamping screw 13 contacts the left movable block 6. During installation, to overcome the elastic force of the first compression spring, the right movable block 6 is first supported on the cable. The first clamping screw is rotated to drive the left movable block 6 to clamp the cable. At the same time, the first compression spring can play a buffering role and can adapt to cables of different diameters.

[0028] The movable block 6 on the left is provided with a mounting groove 14. The bottom of the mounting groove 14 is inclined backward from bottom to top. The cutter 7 is set in the mounting groove 14 and is close to the bottom of the mounting groove 14. The mounting groove 14 is provided with a pressure block 15 for fixing the cutter 7. The pressure block 15 is fixed to the movable block 6 by screws.

[0029] like Figure 3 and Figure 4 As shown, the rotating ring 3 is provided with a second guide rod 16, and the lifting plate 8 is provided with a slider that cooperates with the second guide rod 16. The second guide rod 16 is provided with a second compression spring 17 that pushes the lifting plate 8 upward. The lower end of the second compression spring 17 contacts the lower end support plate of the second guide rod 16, and the upper end of the second compression spring 17 contacts the slider on the lifting plate. The rotating ring 3 is provided with a second clamping screw 18. The second clamping screw 18 passes through the support plate at the upper end of the second guide rod 16 and is threadedly connected to the support plate. The lower end of the second clamping screw 18 contacts the lifting plate 8. After the inner ring is installed on the cable and the rubber layer of the cable is cut off at one end, the lifting plate 8 descends, and the grinding belt 9 contacts the wire core to grind the wire core.

[0030] like Figure 3 As shown, the lower end of the lifting plate 8 is provided with a groove 19 to prevent interference between the lifting plate 8 and the cable.

[0031] like Figure 3 As shown, the lifting plate 8 has pulleys 20 at both ends that cooperate with the grinding belt 9. A motor is mounted on the rotating ring 3, and the motor output shaft is connected to the rotating shaft of one pulley 20 via a connecting mechanism. The connecting mechanism includes a first connecting rod 21, a second connecting rod 22, a first belt 23, and a second belt 24. The first connecting rod 21 and the second connecting rod 22 are hinged, and a rotatable pin is provided at the hinge point. The end of the first connecting rod 21 away from the second connecting rod 22 is rotatably connected to the motor output shaft, and the end of the second connecting rod 22 away from the first connecting rod 21 is rotatably connected to the rotating shaft of the pulley 20. The rotating shaft of the pulley 20 is connected to the motor output shaft via the first belt 23 and the second belt 24.

[0032] Since the lifting plate can be raised and lowered, and the rotation of the pulley 20 requires it to be connected to the motor output shaft, the rotation of the motor output shaft drives the pulley 20 to rotate to perform the grinding action, which can be achieved through the connecting mechanism.

[0033] In use, when the motor output shaft rotates, it drives the first belt 23 to move, which in turn drives the second belt 24 to move, causing the shaft of the pulley 20 to rotate as well. Here, two coaxial pulleys are fixed on the pivot pin that is hinged between the first connecting rod 21 and the second connecting rod 22. One pulley is connected to the motor output shaft through the first belt 23, and the other pulley is connected to the shaft of the pulley 20 through the second belt 24.

[0034] like Figure 1 As shown, a handle 25 is provided on the outer cylindrical surface of the outer ring 2.
