Description

Technical Field

[0001] The invention relates to the technical field of electric power construction, in particular to an electric power construction cable laying device. Background Art

[0002] Cables usually refer to cables similar to ropes made of several or several groups of wires twisted together. Each group of wires is insulated from each other and often twisted around a center. The entire outer layer is covered with a highly insulating covering. Cables have the characteristics of being energized inside and insulated outside. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multiple strands of wires and an insulating layer, and are used to connect circuits, electrical appliances, etc.

[0003] In the process of power construction, in order to meet the complex circuit transmission requirements, a large amount of cable laying is required. Cable trenches or cable tunnels will be used in the foundation construction process for laying cables. Cables are laid in cable trenches and tunnels, and are generally fixed with brackets. Common brackets are angle steel brackets and prefabricated brackets. There are 7 different models and specifications of angle steel brackets used in cable trenches. Cable brackets include fiberglass cable brackets, composite cable brackets, embedded cable brackets, screw-type cable brackets, combined cable brackets, etc. Cable brackets generally need to have the advantages of high strength, good toughness, corrosion resistance, high insulation performance, and good flame retardancy.

[0004] After the bracket is installed in the cable trench, the internal space is small and complex, and the cable wiring process is also relatively complicated. Therefore, the current cable laying in the cable trench is still mainly done manually. Generally, multiple workers stand in the cable trench, transfer each cable in turn, and place the cables on the corresponding brackets in turn. After the arrangement is completed, they are manually tied and fixed. During the circuit construction process, the cable laying process occupies a lot of workload and construction time, which is the main reason for the long project period.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 8 In an embodiment of the present invention, a cable laying device for power construction includes a base 1; a wiring structure 7, a guide structure 6 and a transmission structure 3 are sequentially installed on the base 1; the guide structure 6 includes a turntable 61 rotatably installed on the base 1, and opposite support rods 64 and auxiliary rods 62 are vertically installed on both sides of the turntable 61; a plurality of positioning structures 9 are installed on the support rod 64, and a cross bar 63 is rotatably installed on the outer side of the positioning structure 9, and the cross bar 63 is connected to the auxiliary rod 62 through a snap-on structure 8; an outlet structure 5 is installed at one end of the cross bar 63 away from the auxiliary rod 62, and the outlet structure 5 includes a support frame 51 installed at one end of the cross bar 63, and a plurality of parallel-arranged outlet rollers 52 are installed on the support frame 51; a plurality of cables 4 passing through the wiring structure 7 are placed on the wiring structure 7, and after passing through the transmission structure 3, the cables 4 are sequentially placed in parallel on each outlet roller 52;

[0033] The routing structure 7 is used to limit the position of the pulled cable 4, and the transmission structure 3 is used to drive the cable 4 to output to one side of the outgoing structure 5;

[0034] The guide structure 6 is used to install the outgoing wire structure 5, and the outgoing wire structure 5 is fixed to both sides of the base 1 by rotating the turntable 61;

[0035] The positioning structure 9 is used to adjust the height of the cross bar 63 and the outlet structure 5 so that the outlet structure 5 is inserted into the gap between the two rows of cable brackets. The buckle structure 8 is used to limit the cross bar 63 so that the cross bar 63 is in a horizontal state.

[0036] The device can be pushed by an operator and moved in the cable trench. Before use, the device is placed at one end of the cable trench, and the turntable 61 is rotated and fixed so that the outgoing wire structure 5 is located on one side of the cable 4 to be laid, and the position of the positioning structure 9 is adjusted so that each outgoing wire structure 5 is located at a position higher than each cable bracket. The cable 4 to be laid passes through the routing structure 7 from the side opposite to the cable 4 to be laid, then bypasses the transmission structure 3, and finally reaches the outgoing wire structure 5, and is laid on the corresponding outgoing wire roller 52. The middle part of the outgoing wire roller 52 is concave, which is convenient for limiting the position of the cable 4. After the preliminary arrangement is completed, the end position of the cable 4 is fixed, and then the device is pushed to move in the cable trench. As the device moves forward, the transmission structure 3 continuously pulls the cable 4 from the side of the routing structure 7 as a supplement, and the cable 4 is transported to the outgoing wire structure 5, rolls down along the outgoing wire roller 52, and just falls on the corresponding cable bracket.

[0037] This device can lay multiple cables 4 at a time, and can lay all the cables 4 on the same side of the cable trench in one round of operation, and automatically complete the work of pulling the cables 4 and placing the cables 4 on the corresponding cable racks. Therefore, this device can significantly improve the efficiency of laying the cables 4 and reduce the workload.

[0038] The cross bar 63 and the support bar 64 are connected in a rotating manner so that after use, the width of the device can be reduced by lowering the cross bar 63, making the device easier to move, and when the output line structure 5 is rotated, it can also avoid collision between the output line structure 5 and the routing structure 7.

[0039] As another embodiment of the present invention, please refer to Figures 1 to 5, a limit plate 53 is buckled and installed on the support frame 51, and the limit plates 53 are connected to the support frame 51 on both sides by limit screws 54. The limit plate 53 is fixed to the support frame 51 by the limit screws 54. After the initial fixation of the cable 4 is completed, the position of the cable 4 can be further limited to avoid the movement of the cable 4 during the laying process, which leads to the problem of chaotic laying. The limit plate 53 and the limit screw 54 are not restrictive structures, but an improved structure that can be selected. In order to further improve the use effect, the corresponding outlet roller 52 can also be installed on the inner side of the limit plate 53 to further locate the position of the cable 4. The limit screw 54 is only an optional connection method, and a hinged connection with a lock buckle or other connection methods can be used as an alternative.

[0040] See also Figure 5 , Figure 7 and Figure 8 , a plurality of wedge-shaped positioning saw teeth 641 are respectively provided on both sides of the support rod 64, and the positioning structure 9 includes a positioning box 91 sleeved on the support rod 64, and wedge-shaped positioning blocks 92 are slidably installed on both sides of the interior of the positioning box 91, and the shapes of the positioning blocks 92 and the positioning saw teeth 641 cooperate with each other. The upper end of the positioning saw teeth 641 is a horizontal plane, and the lower end is inclined. The positioning block 92 is stored inside the positioning box 91, and the positioning box 91 can slide up and down along the support rod 64 to change the height of the cross bar 63 and the outlet structure 5. After reaching the specified height, the positioning block 92 moves inward and is inserted into the corresponding recess of the positioning saw teeth 641, so that the positioning box 91 can be fixed at the current position.

[0041] See also Figure 5 , Figure 7 and Figure 8 The two sides of the positioning box 91 are respectively provided with rotating shafts 911, and the cross bar 63 is provided with a through slot 632 which is sleeved on the positioning box 91. The rotating shaft 911 passes through the through slot 632 and is rotatably connected with the cross bar 63. The rotating shaft 911 is located on both sides of the positioning box 91. Since the cross bar 63 of the device needs to have a rotating function, the cross bar 63 is installed in a rotatably connected manner with the rotating shaft 911.

[0042] See also Figure 5 , Figure 7 and Figure 8, a top block 94 penetrating the rotating shaft 911 is inserted into the positioning box 91, and one end of the top block 94 inserted into the positioning box 91 is connected to the inner wall of the positioning box 91 through a primary spring 95, and both sides of the top block 94 are connected to the positioning blocks 92 located on both sides of the support rod 64 through connecting rods 93. The top block 94 passes through the rotating shaft 911, and the primary spring 95 has a tendency to stretch, so that the top block 94 remains in a state of passing through the rotating shaft 911, and the top block 94 pulls the connecting rod 93, so that the connecting rod 93 drives the positioning block 92 to move toward the middle and get stuck on the support rod 64, and the top block 94 is pressed inward, so that the positioning block 92 is squeezed outward and disengaged from the positioning serrations 641. In this state, the positioning box 91 and the cross bar 63 can slide on the support rod 64.

[0043] See also Figure 7 A groove 631 corresponding to the position of the cross bar 63 is formed at one end of the cross bar 63 close to the auxiliary bar 62, and a mounting groove 633 is formed inside the cross bar 63. The buckle structure 8 includes an insertion rod 81 slidably inserted into the mounting groove 633. A plurality of through holes 621 are formed on the auxiliary bar 62. The insertion rod 81 passes through the through holes 621. The insertion rod 81 is connected to the inner wall of the mounting groove 633 through a secondary spring 83. An operating rod 82 is installed on the insertion rod 81 and passes through the surface of the cross bar 63. The groove 631 on the cross bar 63 is sleeved on the auxiliary rod 62, and the through hole 621 on the auxiliary rod 62 is used to position the insertion rod 81. The cross bar 63 can rotate relative to the positioning box 91, so the connection between itself and the auxiliary rod 62 is a movable connection. When the outer end of the cross bar 63 droops, the cross bar 63 does not contact the auxiliary rod 62. During the wiring process, the cross bar 63 is in a horizontal state, and the insertion rod 81 is inserted into the corresponding through hole 621 to fix the cross bar 63. When the direction of the output structure 5 needs to be changed, the insertion rod 81 is moved backward by the operating rod 82, and the cross bar 63 will be released from the connection with the auxiliary rod 62, and the output structure 5 can be tilted and drooped.

[0044] See also Figures 1 to 4The base 1 is connected to a top plate 14 through a support column 12, an inverted V-shaped baffle 13 is installed between the base 1 and the top plate 14, and the baffle 13 covers the area of ​​the transmission structure 3. The transmission structure 3 includes a driving roller 32 rotatably installed between the base 1 and the top plate 14, and a motor 34 connected to the driving roller 32 is installed on the top plate 14. Auxiliary rollers 33 located on both sides of the driving roller 32 are installed on the base 1, and a plurality of horizontally recessed wire grooves 331 are opened on the auxiliary rollers 33. The top plate 14 is fixed by the support column 12, and cooperates with the base 1 to enhance the stability of each rotatable mechanism. The baffle 13 is located at the front end of the device. During the movement of the device, it can block the cable bracket at the front to avoid the problem of collision between the cable bracket and the internal structure of the device due to the tilt of the moving track. The motor 34 can drive the driving roller 32 to rotate, and the cable 4 is wound around the driving roller 32. As the driving roller 32 rotates, the cable 4 can be pulled. The auxiliary rollers 33 on both sides are used to stabilize the cable 4 at the required height. Since the cable 4 has a large weight and the cables 4 of the device are arranged vertically, in order to prevent the cable 4 from sliding down and accumulating at the driving roller 32, resulting in the problem of ineffective traction, the wire grooves 331 on the auxiliary rollers 33 are needed to support the cable 4 and prevent the cable 4 from falling prematurely. The height difference between the cable 4 at the driving roller 32 and the outlet structure 5 can also make the cable 4 discharge more smoothly.

[0045] See also Figures 1 to 5 The base 1 and the top plate 14 are respectively provided with telescopic structures 2, a pressure roller 31 is connected between the telescopic structures 2, the pressure roller 31 and the driving roller 32 are parallel to each other, the telescopic structure 2 includes a telescopic rod 21 installed on the base 1 and the top plate 14, the telescopic rod 21 is connected to the mounting block 23, the pressure roller 31 is rotatably connected to the mounting block 23, and a three-stage spring 22 is sleeved on the telescopic rod 21. The pressure roller 31 is pressed on the surface of the driving roller 32 to increase the pressure between the cable 4 and the driving roller 32. The telescopic structure 2 uses the three-stage spring 22 to push the pressure roller 31, which can maintain the pressure of the pressure roller 31 and meet the transmission requirements of cables 4 of different diameters. The telescopic structure 2 of the device can be replaced by a hydraulic telescopic structure 2 or a screw telescopic structure 2, etc. In addition, the number of the pressure rollers 31 can also be set to two or more as needed, and the description in this regard is not restrictive.

[0046] See also Figure 4 and Figure 6The base 1 is provided with a semicircular primary limiting groove 15 and a secondary limiting groove 17 around the turntable 61, and two opposite positioning posts 614 are respectively installed at both ends of the turntable 61, and the positioning posts 614 are respectively inserted into the primary limiting groove 15 and the secondary limiting groove 17, and pin holes 612 corresponding to the positions of the primary limiting groove 15 and the secondary limiting groove 17 are respectively opened at both ends of the turntable 61. A connecting plate 611 is provided on the turntable 61, and column pins 613 passing through the two pin holes 612 are respectively installed at both ends of the connecting plate 611, and the column pins 613 are respectively inserted into the primary limiting groove 15 and the secondary limiting groove 17. The turntable 61 is rotatably connected to the base 1, and the positioning column 614 inserted into the primary limit groove 15 and the secondary limit groove 17 is used to enhance the connection effect. The device requires the turntable 61 to be able to rotate 180 degrees, so a connecting plate 611 and a pin 613 are set. The pin 613 and the positioning column 614 located on the same annular surface are respectively located on both sides of the turntable 61, that is, a pin 613 and a positioning column 614 are respectively installed at both ends of the primary limit groove 15, and a pin 613 and a positioning column 614 are also respectively installed at both ends of the secondary limit groove 17. Through the restriction in two directions, the turntable 61 can be fixed. When rotation is required, the connecting plate 611 is operated to pull out the pin 613, and the turntable 61 can be rotated 180 degrees and then fixed again. The above structure is only used as a demonstration of the connection method between the turntable 61 and the base 1, and is not restrictive. In addition to using the turntable 61 structure of the present device, screws and other methods can also be used to fix the turntable 61. Since the present device can directly change the limit relationship by raising or lowering the connecting plate 611 during operation, it is more convenient to use than other installation methods.

[0047] See also Figures 1 to 4 The wiring structure 7 includes two wiring rods 72 relatively installed on both sides of the base 1, and a plurality of vertically arranged wiring rollers 71 are installed on the outer side of the wiring rods 72.

The wheels 11 at the bottom cooperate with the drive system 16 to realize the automatic movement of the device, and the drive system 16 is also used to provide drive for the motor 34 and realize the linkage between the drive roller 32 and the wheel 11. The wiring rods 72 are located on both sides of the device. The wiring rods 72 on one side can be selected for use as needed. The path for the cable 4 to be supplemented forward is located on the side of the operator, which does not affect the operator's operation of the device.

[0048] The working principle of the present invention is:
