Description

Technical Field

[0001] The present invention relates to the technical field of cable laying, and in particular to a power system cable laying device and a use method thereof. Background Art

[0002] Cable is a collection of conductors used to transmit electrical energy, signals or data. It is widely used in power systems, communication systems and various industrial and civil fields. Cable is mainly composed of conductor, insulation layer, shielding layer and sheath.

[0003] The existing cable laying technology is to set up the cable roller near the cable conveyor. The workers are at the front end of the conveyor output direction. During the process of conveying the cable through the conveyor, the workers pull the end of the cable forward. Since the cable body is thick and has a certain weight, when laying underground, when the walking route becomes narrow or encounters obstacles, the workers need to stop and adjust the position of the cable to facilitate cable laying. During this process, if the cable is continuously released and output forward, it will cause cable accumulation and excessive bending of the line body, and may also hit the workers' limbs. In addition, since the cable is evenly wound on the roller, when released, the cable near the two ends of the roller will be in a state of oblique pulling with the conveyor, which will increase the resistance of the cable when released, which is not conducive to protecting the cable structure, so it needs to be improved.

[0014] Preferably, the wire-releasing box is symmetrically provided with limiting holes, and the aperture of the limiting holes is larger than the diameter of the connection between the guide wheel and the wire-releasing box.

[0015] Preferably, a method for using a power system cable laying device comprises the following steps:

[0016] S1: Before the cable laying begins, the spacing between the movable frame and the fixed frame is enlarged by rotating the adjustment rod, and the two ends of the roller shaft wrapped with the cable are respectively installed on the movable frame and the fixed frame. The two turntables on the movable frame and the fixed frame clamp the two ends of the roller shaft. During this process, the top rod is clamped in the straightening frame, and then the end of the cable is inserted into the wire-releasing box through the hole. Then the drive motor is started, the worm gear drives the worm wheel to rotate, and the worm gear drives the fan-shaped gear to swing back and forth through the connecting rod. During the process, the transmission double-headed gear rotates continuously, and the rack slides back and forth on the frame. Through the clamping hole and the clamping head, the connecting seat and the wire-releasing box are driven to slide back and forth on the frame. During the cable release process, the cable on the roller shaft is always kept in a straight and flat state;

[0017] S2: During the movement of the cable pay-off box, the connecting rod 2 pulls the turntable to rotate continuously, and the turntable always keeps unidirectional rotation. During the rotation, the limit head is frequently pushed, and the limit head prevents the one-way wheel from reversing. The top of the one-way wheel rotates the rotating rod continuously through the bevel gear 1 and the bevel gear 2. Through the rotation, the two bevel gears 4 drive the bevel gear 3 to rotate. During the rotation, the guide wheel and the end of the cable are in a close contact state. The two guide wheels rotate in opposite directions, so that the cable is output and passes through the cable pay-off box. The cable is continuously output for laying work;

[0018] S3: When the cable laying path is blocked, the operator holds the hand between the bracket and the control rod, operates the control rod to rotate toward the bracket, and the half gear rotates to drive the tooth plate to slide downward. During the frame moving downward, the clamping head is disengaged from the clamping hole of the rack, and the wire box is disconnected from the driving mechanism. The wire box stops moving, and then the roller contacts the side of the wedge plate when the frame continues to move downward, so that the two wedge plates are squeezed and move toward the middle of the wire box at the same time, and the two guide wheels are driven relatively close to each other by the connecting piece. The two guide wheels clamp the cable Tighten to prevent the cable from loosening. During this process, the mounting ring slides a corresponding distance in the guide groove. While the clamp moves downward, the pressure plate is pressed down to drive one end of the pry bar to move downward, and the other end of the pry bar is tilted upward to move the push rod upward. When the push rod moves upward, it generates friction with the arc piece and pushes the arc piece, so that the arc piece approaches the edge of the live frame, thereby driving the brake piece to move synchronously. The inner side of the brake piece sticks to the rotating disk of the live frame. After friction is generated, the rotating disk slows down and stops rotating, preventing the cable from continuing to be released due to inertia when the laying path is blocked.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, the drive mechanism is set up so that the rack drives the wire box to slide back and forth on the frame through the clamp head and the connection seat. During the working process, the cable is driven to move back and forth for laying, so that the inclined angle of the cable close to the two ends of the roller shaft is greatly reduced when it is released, and the resistance generated thereby is reduced, which is conducive to the smooth release of the cable and the protection of the cable body structure;

[0021] 2. In the present invention, by setting a control lever, when the cable laying path is blocked, the operator of the device pulls the control lever to make the tooth plate slide downward through meshing with the half gear, so that the clamp installed at the bottom of the frame is disengaged from the rack, and the release box stops moving. When it is necessary to stop releasing the cable, the active output power of the cable can be quickly cut off, which is convenient for protecting the main structure of the cable and the personal safety of the workers;

[0022] 3. In the present invention, after the cable output is cut off, the drum pushes the two wedge blocks to be relatively close to each other during the downward movement, so that the connecting member drives the two guide wheels to be relatively close to each other when they are synchronously close to each other, so that the clamping force applied by the two guide wheels to the cable sheath is strengthened, and the cable is finally clamped, so that the cable will not continue to be output outward due to inertia, so as to better control the cable output distance;

[0023] 4. In the present invention, by means of the arranged pry bar, during the downward movement of the chuck, one end of the transmission pry bar tilts upward, causing friction between the top rod and the arc piece, and pushing the arc piece and the brake piece toward the rotating disk of the movable frame, generating friction with the rotating disk and finally sticking to it, and at the same time of stopping the cable output, the cable roller stops rotating, preventing the cable roller from continuing to rotate due to inertia, thereby causing the cable to continue to be released for a certain distance, which is beneficial to further protect the cable body structure and improve the safety during the laying process.

[0048] Embodiment three:

[0049] The side end of the pressure plate 509 is rotatably connected to a pry bar 512, the middle part of the pry bar 512 is rotatably connected to the base 1, the top of the pry bar 512 away from the pressure plate 509 is rotatably connected to a push rod 513, the push rod 513 is in contact with the outer surface of the arc piece 208, the outer surface of the brake plate 207 is fixedly connected to the arc piece 208, and the shape of the arc piece 208 is a skewed arc;

[0052] The use method and advantages of the present invention: The use method of the power system cable laying device, the working process is as follows:

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 As shown:

[0054] S1: Before the cable laying begins, the spacing between the movable frame 203 and the fixed frame 202 is enlarged by rotating the adjusting rod 204, and the two ends of the roller shaft wrapped with the cable are respectively installed on the movable frame 203 and the fixed frame 202. The two turntables 503 on the movable frame 203 and the fixed frame 202 clamp the two ends of the roller shaft. During this process, the top rod 513 is clamped in the straightening frame 205, and then the end of the cable is inserted into the wire-releasing box 601 through the perforation 602. Then the driving motor 301 is started, and the worm 302 drives the worm wheel 303 to rotate. The worm wheel 303 drives the fan-shaped tooth piece 305 to swing back and forth through the connecting rod 1 304. During the process, the transmission double-headed gear 306 rotates continuously, and the rack 307 slides back and forth on the frame 4. Through the clamping hole 308 and the clamping head 617, the connecting seat 501 and the wire-releasing box 601 are driven to slide back and forth on the frame 4. During the cable release process, the cable on the roller shaft is always kept in a straight and flat state;

[0055] S2: During the movement of the wire-releasing box 601, the connecting rod 2 502 pulls the turntable 503 to rotate continuously, and the turntable 503 always keeps unidirectional rotation. During the rotation, the limit head 511 is frequently pushed, and the limit head 511 prevents the one-way wheel 504 from reversing. The top of the one-way wheel 504 makes the rotating rod 507 rotate continuously through the bevel gear 1 505 and the bevel gear 2 506. Through the rotation, the two bevel gears 4 607 drive the bevel gear 3 604 to rotate. During the rotation, the guide wheel 603 is in a close contact with the end of the cable, and the two guide wheels 603 rotate in opposite directions, so that the cable is output and passes through the wire-releasing box 601, and the cable is continuously output for laying work;

[0056] S3: When the cable laying path is blocked, the operator holds the support 611 and the control rod 613, operates the control rod 613 to rotate toward the support 611, and drives the tooth plate 612 to slide downward when the half gear 614 rotates. The frame 615 follows the downward movement, so that the clamping head 617 is disengaged from the clamping hole 308 of the rack 307, and the wire box 601 is disconnected from the driving mechanism 3. The wire box 601 stops moving, and then the roller 616 contacts the side of the wedge plate 609 when the frame 615 continues to move downward, so that the two wedge plates 609 are squeezed and move toward the middle of the wire box 601 at the same time, and the two guide wheels 603 are relatively close to each other through the connecting member 605. 03 Clamp the cable to prevent it from loosening. During this process, the mounting ring 606 slides a corresponding distance in the guide groove 508. While the clamping head 617 moves downward, the pressing plate 509 is pressed down, so that the pressing plate 509 drives one end of the pry bar 512 to move downward, and the other end of the pry bar 512 tilts upward, so that the push rod 513 moves upward. When the push rod 513 moves upward, it generates friction with the arc piece 208 and pushes the arc piece 208, so that the arc piece 208 approaches the edge of the living frame 203, thereby driving the brake piece 207 to move synchronously. The inner side of the brake piece 207 sticks to the rotating disk of the living frame 203. After friction is generated, the rotating disk is decelerated and stopped, thereby preventing the cable from continuing to be released due to inertia when the laying path is blocked.

8. The method for using the power system cable laying device according to claim 1, characterized in that: The steps include: S1: Before the cable laying starts, the distance between the movable frame (203) and the fixed frame (202) is enlarged by rotating the adjustment rod (204), and the two ends of the roller shaft wrapped with the cable are respectively installed on the movable frame (203) and the fixed frame (202). The two rotating disks (503) on the movable frame (203) and the fixed frame (202) clamp the two ends of the roller shaft. During this process, the top rod (513) is clamped in the straightening frame (205), and then the end of the cable is inserted into the wire box (601) through the perforation (602), and then the start The driving motor (301) drives the worm (302) to rotate the worm wheel (303), and the worm wheel (303) drives the fan-shaped tooth piece (305) to swing back and forth through the connecting rod (304). During the process, the transmission double-headed gear (306) continues to rotate, and the rack (307) slides back and forth on the frame (4). Through the clamping hole (308) and the clamping head (617), the connecting seat (501) and the wire release box (601) are driven to slide back and forth on the frame (4). During the cable release process, the cable on the roller shaft is always kept in a straight and flat state; S2: During the movement of the cable release box (601), the connecting rod 2 (502) pulls the rotating disk (503) to rotate continuously, and the rotating disk (503) always keeps unidirectional rotation. During the rotation, the limit head (511) is frequently pushed, and the limit head (511) prevents the one-way wheel (504) from reversing. The top of the one-way wheel (504) causes the rotating rod (507) to rotate continuously through the bevel gear 1 (505) and the bevel gear 2 (506). Through the rotation, the two bevel gears 4 (607) drive the bevel gear 3 (604) to rotate. During the rotation, the guide wheel (603) is in a close contact with the end of the cable. The two guide wheels (603) rotate in opposite directions, so that the cable is output and passes through the cable release box (601). The cable is continuously output for laying work; S3: When the cable laying path is blocked, the operator holds the support (611) and the control rod (613) by hand, operates the control rod (613) to rotate toward the support (611), so that the half gear (614) rotates and drives the tooth plate (612) to slide downward, and the frame (615) follows the downward movement, so that the clamping head (617) is disengaged from the clamping hole (308) of the rack (307), and the wire release box (601) is disconnected from the driving mechanism (3), and the wire release box (601) stops moving. Then, when the frame (615) continues to move downward, the roller (616) contacts the side of the wedge plate (609), so that the two wedge plates (609) are squeezed and move toward the middle of the wire release box (601), and the two guide wheels (603) are relatively close to each other by a short distance through the connecting member (605), so that the two The guide wheel (603) clamps the cable to prevent it from loosening. During this process, the mounting ring (606) slides a corresponding distance in the guide groove (508). When the clamp head (617) moves downward, the pressing plate (509) is pressed down, so that the pressing plate (509) drives one end of the pry bar (512) to move downward, and the other end of the pry bar (512) tilts upward, so that the push rod (513) moves upward. When the push rod (513) moves upward, it generates friction with the arc piece (208) and pushes the arc piece (208), so that the arc piece (208) approaches the edge of the movable frame (203), thereby driving the brake plate (207) to move synchronously. The inner side of the brake plate (207) sticks to the rotating disk of the movable frame (203). After friction is generated, the rotating disk is decelerated and stops rotating, thereby preventing the cable from being released due to inertia when the laying path is blocked.
