Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable laying equipment, in particular to a cable laying device for power construction and a use method thereof. BACKGROUND

[0002] At present, with the continuous improvement of people's living standards, the demand for mechanical and electrical equipment in daily life is also increasing. With the increase in the number of mechanical and electrical equipment, the number of outdoor mechanical and electrical equipment is also increasing, so it is necessary to redesign and construct the circuit laying method of outdoor mechanical and electrical equipment.

[0003] Cable laying is a process often involved in power construction. The usual construction method is to support the cable shaft on the ground, and pull the end of the cable to lay the cable by manual operation. When the length of the cable is large, multiple workers need to pull the cable at the same time, which consumes manpower. When laying cables outdoors, a cable trench is usually dug first, and multiple supports are installed at equal intervals on the side wall of the cable trench along the preset cable laying path. When the cable needs to be laid in the cable trench, the worker needs to pass the cable through the supports along the laying path one by one, and fix the cable on the supports by a tie.

[0004] In view of the related technology in the above, because the cable trench is relatively narrow and the space occupied by the support is relatively large, in order to pass more cables in the limited space, the supports in the cable trench are generally provided with multiple layers. When laying the bottom layer of cable, the worker needs to pull the cable to a support first, and then pull the cable at the previous support, which is laborious and inconvenient. There is a great safety hazard for the construction personnel to walk between the metal supports and pull the heavy cable. SUMMARY

[0005] In order to improve the problem that manual pulling of the cable is laborious and inefficient due to the small space in the cable trench, the present application provides a cable laying device for power construction and a use method thereof.

[0006] The cable laying device for power construction and the use method thereof provided by the present application adopt the following technical scheme:

[0007] A cable laying device for power construction and a method thereof, comprising a base provided with a roller at the bottom, a rotating disc is rotatably installed on the base, two grippers for clamping the cable are rotatably connected to the rotating disc, the two grippers are respectively located on the two opposite sides of the outer arc side of the rotating disc, a first driving member for driving the rotating disc to rotate is arranged on the base, two sets of tensioning assemblies for driving the grippers to open or close are arranged on the base, the two sets of tensioning assemblies are respectively located on the two opposite sides of the outer arc side of the rotating disc, and one set of the tensioning assemblies drives the first gripper to open at the same time that the other set of the tensioning assemblies drives the second gripper to close; when the grippers are in the open state and rotate to the cable laying track, the end of the gripper away from the rotating disc is located between the cable and the rotating disc.

[0009] Optionally, the rotating disc is provided with a mounting seat, the gripper is mounted on the mounting seat, the gripper comprises two opposite clamping jaws, a first gear is hinged to each clamping jaw, and the two first gears on the same mounting seat are meshed with each other; a first connecting rod is hinged to the middle of the clamping jaw, the other end of the first connecting rod is hinged to the mounting seat, a second connecting rod is hinged to the end of the clamping jaw close to the mounting seat, the other end of the second connecting rod is hinged to the mounting seat, the first connecting rod is parallel to the second connecting rod and has the same length as the second connecting rod; and the base is provided with an intermittent driving assembly for driving the first gear to rotate intermittently.

[0010] By adopting the above technical scheme, the first gear is driven to rotate intermittently through the intermittent driving assembly, when the first gear rotates, the two clamping jaws are close to each other to clamp the cable due to the fact that the clamping jaw is hinged to the first gear and the two ends of the first connecting rod are respectively hinged to the mounting seat and the clamping jaw, so as to realize the effect of driving the gripper to clamp, the first gear is driven to stop rotating through the intermittent driving assembly, and the gripper continuously clamps in the clamped state, thereby improving the problem of loose cable falling off the gripper.

[0011] Optionally, the intermittent driving assembly comprises a grooved wheel coaxially fixed with the first gear, a dial is rotatably connected to the mounting seat, and the dial is adapted to the two grooved wheels on the same mounting seat; and the mounting seat is further provided with a second driving member for driving the dial to rotate.

[0012] By adopting the technical scheme, the dial is driven to rotate by the second driving member, the dial enters the sliding slot of the ratchet wheel and drives the ratchet wheel to rotate, the ratchet wheel drives the first gear to rotate, the two first gears on different claws are engaged with each other, and the two first gears rotate simultaneously, the dial is stopped from rotating by the second driving member when the claws are clamped or separated, and the effect that the first gear is driven to rotate intermittently is realized.

[0015] The mounting seat is rotatably connected with two bevel gears engaged with each other, one of the bevel gears is coaxially fixed with the dial, and the other bevel gear is coaxially fixed with the second gear.

[0016] By adopting the technical scheme, when the gripper rotates to the cable laying track, the auxiliary rack is engaged with the second gear, the second gear is engaged with the auxiliary rack and rotates because the auxiliary rack is fixed and the dial still drives the gripper to rotate, the second gear drives the coaxially fixed bevel gear to rotate, the bevel gear drives the other bevel gear engaged with it to rotate, and then drives the dial to rotate, when the gripper rotates away from the cable laying direction, the second gear is disengaged from the auxiliary rack and stops rotating, so that the dial also stops rotating, and the effect that the dial is driven to rotate intermittently is realized.

[0017] Optionally, a screw rod is threaded through one end of the claw away from the dial, and the two claws are rotatably connected with pads on the side close to each other.

[0018] By adopting the technical scheme, when different specifications of cables are laid, the worker drives the two pads to move close to or away from each other by rotating the screw rod, and the two pads hold the cable tightly, the setting of the pads not only enhances the clamping effect of the gripper on the cable, but also increases the contact area between the gripper and the cable, and improves the problem of damaging the cable during the process of the gripper clamping the cable.

[0019] Optionally, two oppositely arranged rotating rollers are rotatably connected to the side of the base facing the traction direction of the cable.

[0020] By adopting the technical scheme, the cable moves forward and drives the rotating rollers to rotate, the rotating rollers guide the moving cable, so that the cable enters the gripper more smoothly, and the setting of the rotating rollers makes the cable held and rotated by the gripper always in a taut state, and the rotating rollers improve the problem of the cable winding before entering the gripper.

[0022] By adopting the above technical solution, when the turntable rotates, the upright foot is always on the ground. When it needs to be moved, after the gripper clamps the cable, the drive component drives the drive rod to move towards the end closer to the upright foot, and the upright foot falls to the ground and stabilizes on the ground, which improves the problem of the base being unstable due to excessive force when pulling the cable.

[0023] Optionally, a limiting groove is provided on the drive rod, and the drive assembly includes a third gear rotatably connected to the base, a slide rod hinged to the third gear, and the slide rod slidably connected in the limiting groove; two arc-shaped racks are fixed to the outer periphery of the turntable, and the two arc-shaped racks are respectively located at the two ends of the turntable near the chuck, and the third gear and the arc-shaped racks mesh with each other; when the third gear meshes from one end of the arc-shaped rack to the other end, the third gear rotates exactly one revolution, and when the third gear rotates one revolution, the slide rod slides back and forth in the limiting groove.

[0024] By adopting the above technical solution, when the gripper rotates to the cable laying track, the third gear contacts and meshes with the arc-shaped rack. The arc-shaped rack drives the third gear to rotate, and the third gear drives the slide rod to slide in the limit groove. The slide rod drives the drive rod to move, thus achieving the effect of driving the drive rod to move.

[0025] Optionally, the end of the base away from the roller is fixed with anti-slip spikes.

[0026] By adopting the above technical solution, the anti-slip spikes improve the problem of slippage when standing on the ground inside the cable trench, making it easier to stand more stably.

[0027] Optional, the following steps may be included:

[0028] S1. Before construction, move the base into the cable trench and position the gripper above the bracket, and place the cable between the two claws;

[0029] S2.

By adopting the technical scheme, before the cable is laid, the base is moved to a suitable position, the cable is placed between the grippers, and then the first driving member is started to drive the rotating disc to rotate, the rotating disc drives the gripper to rotate, the cable is tightly held by the gripper when the gripper is in the cable laying direction, and the other gripper is separated at the same time, the rotation of the gripper drives the cable to move forward, and when the gripper rotates by half, the cable is released by the gripper, and the other gripper holds the cable, thereby improving the problem that manual traction of the cable is laborious and low in efficiency due to small space in the cable trench.

[0037] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0038] This application discloses a cable laying device for power construction and its usage method. (Refer to...) Figure 1 , Figure 2 A cable laying device for power construction includes a base 1 with rollers 11 at the bottom, a turntable 2 rotatably mounted on the base 1, and two grippers 3 for clamping cables 7 rotatably connected to the turntable 2. The two grippers 3 are located at two opposite ends of a diameter of the turntable 2. The base 1 is provided with a first driving member 12 for driving the turntable 2 to rotate. The first driving member 12 can be a DC motor or an AC motor. In this embodiment, the first driving member 12 is a DC motor. The base 1 is provided with a tensioning component for driving the grippers 3 to open or close. The base 1 is also fixed with a pusher (not shown in the figure) for easy pushing by workers.

[0039] Reference Figure 1 , Figure 2 To improve the problem of contact and collision between the gripper 3 and the cable 7 during the movement from the open position to the closed position, the two tensioning components are respectively located on two opposite sides of the outer arc side of the turntable 2, and one set of tensioning components drives the first gripper 3 to open while the other set of tensioning components drives the second gripper 3 to close; when the gripper 3 is in the open state and rotates to the cable 7 laying track, the end of the gripper 3 away from the turntable 2 is located between the gripper 3 and the turntable 2.

[0040] The user opens the gripper 3 through the tensioning assembly, puts the cable 7 into the gripper 3, and then closes the gripper 3 through the tensioning assembly. The first driving member 12 drives the rotation of the rotating disc 2, and the rotating disc 2 drives the gripper 3 to move along the circumference of the rotating disc 2. The gripper 3 drives the cable to move forward, and the other gripper 3 moves in the direction of approaching the cable 7. When the gripper 3 is in the open state and rotates to the laying track of the cable 7, the end of the gripper 3 away from the rotating disc 2 is located between the gripper 3 and the rotating disc 2, and the gripper 3 does not collide with the cable 7, thereby improving the problem of labor and low efficiency caused by small space in the cable trench.

[0041] In order to realize the tensioning of the gripper 3 for clamping the cable 7, referring to Figure 1 、 Figure 2 The rotating disc 2 is rotationally connected with a mounting seat 21, and the gripper 3 is mounted on the mounting seat 21. The gripper 3 includes two opposite clamping jaws 31, and the clamping jaw 31 is hingedly connected with a first gear 32. The first gears 32 on the two clamping jaws 31 on the same mounting seat 21 are in meshing connection. The clamping jaw 31 is hingedly connected with a first connecting rod 331 at the middle part, and the other end of the first connecting rod 331 is hingedly connected with the mounting seat 21. The end of the clamping jaw 31 close to the mounting seat 21 is hingedly connected with a second connecting rod 332, and the other end of the second connecting rod 332 is hingedly connected with the mounting seat 21. The first connecting rod 331 is parallel to the second connecting rod 332 and has the same length. The two ends of the first connecting rod 331 are hingedly connected at the two ends of the second connecting rod 332, and the four intersection points of the parallelogram are formed. The base 1 is provided with an intermittent driving assembly for driving the first gear 32 to rotate intermittently.

[0042] The first gear 32 is driven to rotate intermittently by the intermittent driving assembly. When the first gear 32 rotates, the clamping jaw 31 is hingedly connected with the first gear 32, and the two ends of the first connecting rod 331 are hingedly connected with the mounting seat 21 and the clamping jaw 31, respectively. The two clamping jaws 31 are close to each other to clamp the cable 7. Since the first connecting rod 331 and the second connecting rod 332 cooperate with the clamping jaw 31 and the mounting seat 21 to form a movable parallelogram, the two clamping jaws 31 are close to each other while extending away from the rotating disc 2, thereby achieving the effect of driving the gripper 3 to clamp. When the intermittent driving assembly drives the first gear 32 to stop rotating, the gripper 3 is continuously in the clamping state, thereby improving the problem of the gripper 3 loosening and falling off the cable 7.

[0043] In order to drive the first gear 32 to rotate intermittently, referring to Figure 1 、 Figure 2The intermittent driving assembly comprises a groove wheel 34 coaxially fixed with the first gear 32, a dial 35 rotatably connected to the mounting base 21, and the dial 35 is adapted to the groove wheel 34 on the two clamping jaws 31 on the same mounting base 21 and located between the two groove wheels 34, and when the dial 35 rotates half a circle, the distance between the two clamping jaws 31 moves from maximum to minimum or from minimum to maximum; the mounting base 21 is further provided with a second driving member for driving the dial 35 to rotate.

[0044] In another possible embodiment, the intermittent driving assembly can comprise a second gear 39 engaged with the two first gears 32 and located between the two first gears 32, and the mounting base 21 is provided with a motor for driving the second gear 39 to rotate intermittently. Considering that the control of the motor is difficult to control completely accurately, after the distance between the two clamping jaws 31 is adjusted appropriately, the dial 35 is disengaged from the sliding groove of the groove wheel 34, the arc surface part of the dial 35 is attached to the arc surface part of the groove wheel 34, the groove wheel 34 stops rotating, and the problem that the adjusted distance between the clamping jaws 31 deviates due to the difficulty in controlling the motor is improved.

[0045] The dial 35 is driven to rotate by the second driving member, the dial 35 enters a sliding groove of a groove wheel 34 and drives the groove wheel 34 to rotate, the groove wheel 34 drives the first gear 32 to rotate, and since the two first gears 32 on different clamping jaws 31 are engaged with each other, the two first gears 32 rotate at the same time. When the clamping jaws 31 are clamped or separated, the dial 35 is stopped from rotating by the second driving member, and the effect of driving the first gear 32 to rotate intermittently is achieved.

[0046] In order to drive the dial 35 to rotate, the second driving member can be a servo motor. However, considering the problem that it is troublesome and wastes energy to control the opening and closing of the motor, with reference to Figure 1 、 Figure 2 The base 1 is fixedly connected with a support 131, the height of the support 131 is the same as the height of the axis of the rotating disc 2, the second driving member comprises two auxiliary racks 132 fixedly connected to the support 131 and a second gear 39 engaged with the auxiliary racks 132, the auxiliary racks 132 are provided with arc surfaces identical to the arc surface of the rotating disc 2 and the tooth parts are directed to the center of the rotating disc 2, and the second gear 39 is rotatably connected to the mounting base 21; when the second gear 39 rotates from one end of the auxiliary rack 132 to the other end, the two clamping jaws tightly hold or release the cable 7; when the gripper 3 rotates to the laying track of the cable 7, the two auxiliary racks 132 are engaged with the two second gears 39, respectively; the mounting base 21 is rotatably connected with two bevel gears 36 engaged with each other, one of the bevel gears 36 is coaxially fixed with the dial 35, the other bevel gear 36 is coaxially fixed with the second gear 39, and the mounting base 21 is further provided with a limiting member for limiting the direction of the rotation axis of the bevel gear 36 coaxially fixed with the dial 35.

[0047] When the gripper 3 rotates to the cable 7 laying direction, the auxiliary rack 132 is engaged with the second gear 39, and since the auxiliary rack 132 is fixed and the rotating disc 2 is still driving the gripper 3 to rotate, the second gear 39 is engaged with the auxiliary rack 132 and rotates, the second gear 39 drives the coaxially fixed bevel gear 36 to rotate, the bevel gear 36 drives another bevel gear 36 engaged therewith to rotate, thereby driving the dial 35 to rotate, when the gripper 3 rotates away from the cable 7 laying direction, the second gear 39 is disengaged from the auxiliary rack 132 and stops rotating, so that the dial 35 also stops rotating, thereby achieving the effect of intermittently driving the dial 35 to rotate.

[0048] In view of the clamping process of the gripper 3, in order to be suitable for more specifications of the cable 7, with reference to Figure 1 、 Figure 2 , a threaded rod 37 is threaded through the end of the gripper 3 away from the rotating disc 2, the axial direction of the threaded rod 37 is the same as the clamping direction of the gripper 3, in view of the fact that when the cable 7 is replaced, the specification difference between the two cables 7 may be large, which may cause the local clamping force to be too large and damage the protective sleeve of the cable 7, the end of the threaded rod 37 close to the gripper 3 is rotationally connected with an arc-shaped pad 38, the pad 38 can be a foam layer, a rubber layer or the like with soft texture, in the embodiment of the present application, the pad 38 is a rubber layer.

[0049] When laying cables 7 of different specifications, the worker rotates the threaded rod 37 to make the two pads 38 close to or away from each other, the two pads 38 tightly hold the cable 7, the arrangement of the pad 38 not only enhances the clamping effect of the gripper 3 on the cable 7, but also increases the contact area between the gripper 3 and the cable 7, thereby improving the problem of damaging the cable 7 during the process of the gripper 3 clamping the cable 7.

[0050] In view of the fact that the cable 7 may not be completely straight due to bending, which makes it difficult for the gripper 3 to tightly hold the cable 7, with reference to Figure 1 , two oppositely arranged rotating rollers 41 are rotationally connected to the base 1, the rotating rollers 41 are "V"-shaped rollers, grooves 42 for the cable 7 to pass through are formed in the rotating rollers 41, and the rotating direction of the rotating rollers 41 is the same as the rotating direction of the rotating disc 2; in addition, rotating rollers 41 are rotationally connected to both ends of the base 1 along the laying direction of the cable 7.

[0051] The cable 7 moves forward and drives the rotating rollers 41 to rotate, the rotating rollers 41 guide the moving cable 7, so that the cable 7 more smoothly enters the gripper 3, and the arrangement of the rotating rollers 41 makes the cable 7 held and rotated by the gripper 3 always in a taut state, thereby improving the problem of the cable 7 winding before entering the gripper 3.

[0052] In view of the fact that the force for pulling the cable 7 is large, since the base 1 is provided with the rollers 11 below for easy movement, the base 1 may not be stable during pulling, with reference toFigure 1 The base 1 is provided with a stand 14, one end of the stand 14 is hinged to the base 1, and the side of the base 1 away from the roller 11 is slidingly connected with a driving rod 51. The base 1 is provided with a driving assembly for driving the driving rod 51 to move.

[0053] When the rotating disc 2 rotates, the stand 14 is always on the ground. When it is necessary to move, after the gripper 3 clamps the cable 7, the driving rod 51 is driven to move to the end close to the stand 14 by the driving assembly, the stand 14 falls to the ground and is stabilized on the ground, thereby improving the problem that the base 1 is unstable due to excessive force of pulling the cable.

[0054] In order to realize the movement of the driving rod 51, with reference to Figure 1 The driving rod 51 is provided with a limiting groove 511. The driving assembly comprises a third gear 54 rotatingly connected to the base 1, a sliding rod 52 hinged to the third gear 54, and a limiting piece 53 fixed to the end of the sliding rod 52 away from the third gear 54 to prevent the sliding rod 52 from falling out of the limiting groove 511. The outer circumferential side of the rotating disc 2 is fixed with two arc-shaped racks 22, which are respectively located at the two ends of the rotating disc 2 close to the clamping jaw 31. The third gear 54 is engaged with the arc-shaped racks 22. When the third gear 54 is engaged from one end of the arc-shaped rack 22 to the other end, the third gear 54 rotates exactly one turn. When the third gear 54 rotates one turn, the sliding rod 52 slides one round trip in the limiting groove 511.

[0055] When the gripper 3 rotates to the cable laying direction, the third gear 54 is in contact with and engaged with the arc-shaped rack 22. The arc-shaped rack 22 drives the third gear 54 to rotate. The third gear 54 drives the sliding rod 52 to slide in the limiting groove 511. The sliding rod 52 drives the driving rod 51 to move, thereby realizing the effect of driving the driving rod 51 to move.

[0056] In order to facilitate the stand 14 to be more stably located on the ground in the cable trench, the end of the base 1 away from the roller 11 is fixed with anti-skid spikes. The arrangement of the anti-skid spikes improves the problem of slippage of the stand 14.

[0057] Considering that the height of the support is different under different working conditions, with reference to Figure 1 The base 1 is provided with a height adjusting assembly 6 for adjusting the height of the rotating disc 2. The height adjusting assembly 6 can be a hydraulic cylinder, a stepping motor, a servo motor, etc. In the embodiment of the application, the height adjusting assembly 6 is a hydraulic cylinder. The height of the rotating disc 2 is adjusted by the height adjusting assembly 6, thereby increasing the applicability of the application.

[0058] In order to improve the problem of cable 7 winding and knotting on the gripper 3, the gripper 3 can be equidistantly arranged along the circumference of the rotating disc 2, each gripper 3 only grips the cable 7 to advance a certain distance, and the size of the groove wheel 34 and the position and size of the auxiliary rack 132 are correspondingly modified.

[0059] The method comprises the following steps:

[0060] S1. Before construction, the base 1 is moved into the cable trench and the gripper 3 is located above the support, and the cable 7 is placed between the two clamps 31;

[0061] S2. The cable is moved, the gripper 3 far from the end face of the cable 7 is closed while the gripper 3 close to the end face of the cable 7 is opened by the second driving member, the first driving member 12 is started to drive the rotating disc 2 to rotate the gripper 3 along the circumference of the rotating disc 2, and the gripper 3 drives the cable 7 to move forward. Before laying the cable, the base 1 is moved to the appropriate position, the cable 7 is placed between the grippers 3, and then the first driving member 12 is started to drive the rotating disc 2 to rotate, the rotating disc 2 drives the gripper 3 to rotate, the gripper 3 tightens the cable 7 when the gripper 3 is located in the direction of cable laying, and the other gripper 3 is opened, the rotation of the gripper 3 drives the cable 7 to move forward, and when the gripper 3 rotates half a circle, the gripper 3 releases the cable 7 while the other gripper 3 tightens the cable 7, which improves the problem of laborious and low efficiency of manually pulling the cable due to the small space in the cable trench.

[0062] The implementation principle of the cable laying device for power construction and the use method thereof is that the user drives the dial 35 to rotate through the second driving member, the dial 35 enters the sliding groove of one groove wheel 34 and drives the groove wheel 34 to rotate, the groove wheel 34 drives the first gear 32 to rotate, the two clamps 31 are close to each other to clamp the cable 7, the gripper 3 is opened, the cable 7 is placed in the gripper 3, the dial 35 is driven to rotate through the second driving member again, the dial 35 enters the sliding groove of one groove wheel 34 and drives the groove wheel 34 to rotate, the groove wheel 34 drives the first gear 32 to rotate, and then the dial 35 is stopped from rotating through the second driving member, the gripper 3 is in a clamped state, the rotating disc 2 is driven to rotate through the first driving member 12, the rotating disc 2 drives the gripper 3 to move along the circumference of the rotating disc 2, and the gripper 3 drives the cable to move forward, which improves the problem of laborious and low efficiency of manually pulling the cable due to the small space in the cable trench.

[0063] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
