Description

Technical Field

[0001] The utility model relates to the technical field of power transmission line engineering, in particular to a hinged traction walking board. Background Art

[0002] The traction walking plate is a special tool used to connect the traction wire rope and each sub-conductor during the tension wire laying construction of the transmission line project. There are different types such as one-pull-two, one-pull-three, one-pull-four, and one-pull-six.

[0003] A Chinese patent discloses a traction board (authorization announcement number CN207166033U). This patented technology can work all day long and has a traction board with luminous indicators. It has a wide range of applications. In addition to normal use during the day, it can also be used for nighttime construction, effectively solving the problem of real-time understanding of the running position and status of the traction board during nighttime conductor laying construction.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the existing traction walking plate is welded in one piece, and cannot swing according to the position of the pulley groove when the traction plate passes the pulley, resulting in increased resistance when the traction plate passes the pulley. Utility Model Content

[0005] The technical problem to be solved by the utility model is that: the prior art has the disadvantage that the traction board cannot be swung according to the position of the pulley when passing the pulley, so we propose a hinged traction walking board.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a hinged traction walking board, including a walking board body, the front end of the walking board body is fixedly connected to a first connecting block, the front end rotating shaft of the first connecting block is connected to a front end hinge, the front end of the front end hinge is fixedly connected to a traction rope fixing rod, the rear end of the walking board body is fixedly connected to a second connecting block, the rear end rotating shaft of the second connecting block is connected to a rotating rod, the rear end rotating shaft of the rotating rod is connected to a rear end hinge, and the rear end of the rear end hinge is fixedly connected to a sub-conductor fixing rod.

[0007] Preferably, there are multiple second connection blocks.

[0008] Preferably, a guide plate is fixedly connected to the bottom of the walking plate body, the number of the guide plates is the same as the second connecting blocks, and the second connecting blocks and the guide plates are on the same line.

[0009] Preferably, a first sliding groove is provided at the rear end of the walking plate body, a connecting rod is slidably connected inside the first sliding groove, a through hole is provided on the left side of the connecting rod, a round rod is rotatably connected inside the through hole, and a balancing tail hammer is fixedly connected at both ends of the round rod.

[0010] Preferably, a second slide groove is provided at the front end of the first slide groove, the interior of the second slide groove is slidably connected to a sliding block, and the rear end of the sliding block is fixedly connected to the front end of the connecting rod.

[0011] Preferably, a fixing block is fixedly connected to the top of the connecting rod, a threaded rod is internally threadedly connected to the fixing block, and a knob is fixedly connected to the rear end of the threaded rod.

[0012] Technical effects and advantages of the utility model:

[0013] In the utility model, the user fixes the traction rope on the traction rope fixing rod, fixes the rope for laying the circuit to the sub-conductor fixing rod, and pulls the traction rope to pull the rope for laying the circuit to the required position. Since the front hinge and the walking board body are chain-connected, the walking board body can swing when it is subjected to force when passing the pulley, thereby reducing the resistance when the walking board passes the pulley and making traction more labor-saving.

[0014] In the utility model, when the user pulls the traction rope to drive the walking board body to move, the balancing tail hammer at the rear end of the walking board body keeps the walking board body balanced, preventing the walking board body from flipping over during the traction process and causing the laid line to be entangled. When the laid line is odd, the walking board body will tilt due to different weights on both sides, causing the walking board body to be unable to pass the pulley normally. The balancing tail hammer is driven to move by moving the connecting rod, so that the weights on both sides of the walking board body are kept the same. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figure 1 As shown, the utility model provides a technical solution: a hinged traction walking board, including a walking board body 1, a first connecting block 2 is fixedly connected to the front end of the walking board body 1, a front end rotating shaft of the first connecting block 2 is connected to the front end hinge 3, a front end of the front end hinge 3 is fixedly connected to a traction rope fixing rod 4, a rear end of the walking board body 1 is fixedly connected to a second connecting block 5, a rear end rotating shaft of the second connecting block 5 is connected to a rotating rod 6, a rear end rotating shaft of the rotating rod 6 is connected to a rear end hinge 7, a rear end of the rear end hinge 7 is fixedly connected to a sub-wire fixing rod 8, a user fixes the traction rope on the traction rope fixing rod 4, fixes the sub-wire to the sub-wire fixing rod 8, and pulls the sub-wire to a required position by pulling the traction rope. Because the front end hinge 3 and the walking board body 1 are chain-type connected, the walking board body 1 can swing under force when passing the pulley, thereby reducing the resistance of the walking board when passing the pulley and making traction more labor-saving.

[0022] Reference Figure 1 As shown, in this embodiment: the number of second connecting blocks 5 is several, and the user selects the walking board body 1 corresponding to the number of second connecting blocks 5 according to the number of sub-conductors that need to be towed, fixes the traction rope on the traction rope fixing rod 4, fixes multiple sub-conductors to the sub-conductor fixing rod 8, pulls the traction rope, and pulls the sub-conductors on the sub-conductor fixing rod 8 to the required position.

[0023] Reference Figure 2 As shown, in this embodiment: a guide plate 9 is fixedly connected to the bottom of the walking board body 1, the number of the guide plates 9 is the same as the second connecting block 5, and the second connecting block 5 and the guide plate 9 are on the same line, and the user pulls the traction rope to pull the sub-conductor to the required position. In the process of the walking board body 1 passing the pulley, the guide plate 9 at the bottom of the walking board body 1 guides the sub-conductor fixing rod 8, and guides the sub-conductor behind the sub-conductor fixing rod 8 into the groove of the pulley, thereby reducing the resistance during traction.

[0024] Reference Figure 3 and Figure 4As shown, in the present embodiment: a first slide groove 10 is provided at the rear end of the walking board body 1, a connecting rod 11 is slidably connected inside the first slide groove 10, a through hole 12 is provided on the left side of the connecting rod 11, a European round rod 13 is rotatably connected inside the through hole 12, and a balancing tail hammer 14 is fixedly connected at both ends of the round rod 13. When the user pulls the traction rope to drive the walking board body 1 to move, the balancing tail hammer 14 at the rear end of the walking board body 1 keeps the walking board body 1 balanced to prevent the walking board body 1 from flipping over during the traction process and causing the sub-conductor to be entangled. When the sub-conductor is odd, the walking board body 1 will tilt due to different weights on both sides, causing the walking board body 1 to be unable to pass the pulley normally. The balancing tail hammer 14 is driven to move by moving the connecting rod 11, so that the weights on both sides of the walking board body 1 remain the same.

[0025] Reference Figure 4 As shown, in the present embodiment: a second slide groove 15 is provided at the front end of the first slide groove 10, and a sliding block 16 is slidably connected inside the second slide groove 15, and a rear end of the sliding block 16 is fixedly connected to the front end of the connecting rod 11. When the user moves the connecting rod 11 to keep the walking board body 1 horizontal, the second slide groove 15 at the rear end of the connecting rod 11 slides inside the sliding block 16 and limits the connecting rod 11 at the same time to prevent the connecting rod 11 from escaping from the first slide groove 10.

[0026] Reference Figure 4 As shown, in the present embodiment: the top of the connecting rod 11 is fixedly connected with a fixing block 17, the internal thread of the fixing block 17 is connected with a threaded rod 18, and the rear end of the threaded rod 18 is fixedly connected with a knob 19. When the user moves the connecting rod 11 to keep the walking board body 1 horizontal, the second slide groove 15 at the rear end of the connecting rod 11 slides inside the slider 16, and at the same time limits the connecting rod 11 to prevent the connecting rod 11 from escaping from the first slide groove 10. After the position of the connecting rod 11 is adjusted, the knob 19 is rotated to drive the threaded rod 18 to rotate and move forward at the same time, so as to fit with the rear end of the walking board body 1, increase friction, fix the position of the connecting rod 11, and prevent the walking board body 1 from tilting due to displacement during traction.

[0027] The practical working principle of the present invention is as follows: the user fixes the traction rope on the traction rope fixing rod 4, fixes the sub-conductor to the sub-conductor fixing rod 8, and pulls the sub-conductor to the required position by pulling the traction rope. Because the front hinge 3 and the walking board body 1 are chain-connected, the walking board body 1 can be swung by force when passing the pulley, so that the resistance of the walking board passing the pulley is reduced, and the traction is more labor-saving. According to the number of sub-conductors to be towed, the walking board body 1 corresponding to the number of second connecting blocks 5 is selected, and the traction rope is fixed on the traction rope fixing rod 4, and multiple sub-conductors are fixed. The sub-conductor fixing rod 8 is fixed to the sub-conductor fixing rod 8, and the traction rope is pulled to pull the sub-conductor on the sub-conductor fixing rod 8 to the required position. The traction rope is pulled to pull the sub-conductor to the required position. In the process of the walking board body 1 passing the pulley, the guide plate 9 at the bottom of the walking board body 1 guides the sub-conductor fixing rod 8, and guides the sub-conductor behind the sub-conductor fixing rod 8 into the groove of the pulley to reduce the resistance during traction. In the process of the user pulling the traction rope to drive the walking board body 1 to move, the balance tail hammer 14 at the rear end of the walking board body 1 keeps the walking board body 1 balanced. The balance tail hammer 14 is driven by the moving connecting rod 11 to move the balance tail hammer 14, so that the weight on both sides of the walking board body 1 remains the same. In the process of moving the connecting rod 11 to keep the walking board body 1 horizontal, the second slide groove 15 at the rear end of the connecting rod 11 slides inside the slider 16, and the connecting rod 11 is limited to prevent the connecting rod 11 from being separated from the first slide groove 10. In the process of moving the connecting rod 11 to keep the walking board body 1 horizontal, the second slide groove 15 at the rear end of the connecting rod 11 slides inside the slider 16, and the connecting rod 11 is limited to prevent the connecting rod 11 from being separated from the first slide groove 10. After the position of the connecting rod 11 is adjusted, the rotating knob 19 drives the threaded rod 18 to rotate and move forward at the same time, and fits with the rear end of the walking board body 1 to increase the friction force, fix the position of the connecting rod 11, and prevent the walking board body 1 from tilting due to displacement during traction.
