Description

Technical Field

[0001] This invention relates to the field of cable laying technology, and in particular to a cable laying device. Background Technology

[0002] A cable is an electrical or signal transmission device composed of multiple conductors. In order to store, transport and use cables, cables are collected using reels during production and laid out using cable laying equipment to facilitate the laying of cable lines.

[0003] Currently, the cable laying equipment on the market consists of a support frame and jacks. There are two support frames, each with a straight slot. A jack is installed in each straight slot. In use, the support frame is placed on both sides of the shaft of the cable reel, and the shaft is aligned with the jack in the straight slot. Then, the jack is used to lift the cable reel, which ultimately serves to fix and support the cable reel.

[0004] However, in the existing technology, the winding reel is supported and fixed by a support frame and jacks. The structure is simple, easy to move, and has good applicability. However, when supporting and fixing the winding reel, it is necessary to constantly adjust the height of the two jacks to make them at the same height and in a parallel state. The operation is relatively cumbersome and inconvenient to use. Moreover, during the adjustment process, the winding reel is in a tilted state. If it is subjected to external impact, it is easy to collapse, which poses a safety hazard. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the problem that in the prior art, when supporting and fixing the winding reel, it is necessary to constantly adjust the height of the two jacks to make them at the same height and in a parallel state. This operation is cumbersome and inconvenient to use. Moreover, during the adjustment process, the winding reel is in a tilted state, and if it is subjected to external impact, it is easy to collapse, which poses a safety hazard.

[0006] To solve the above-mentioned technical problems, the present invention provides a cable laying device, including a frame; the frame has symmetrically arranged straight slots; a cable reel is rotatably connected in the straight slots; a first leg is fixedly connected to one side of the bottom of the frame; a third leg is fixedly connected to the other side of the bottom of the frame; a second leg is fixedly connected to the top of the frame at a position corresponding to the first leg; a first roller is rotatably connected in each of the first legs; a second roller is rotatably connected in each of the third legs; a handle is fixedly connected between the second legs; a limiting component is fixedly connected between the first rollers, and the limiting component is used to restrict the rolling of the first rollers.

[0007] In one embodiment of the present invention, the limiting component includes a first shaft; ratchet gears are fixedly connected to both ends of the first shaft at positions corresponding to the inner sides of the first leg; a first fixing rod is fixedly connected to each of the first legs at positions corresponding to the ratchet gears above the first leg; a first top block is rotatably connected to each of the first fixing rods; a second fixing rod is fixedly connected to each of the first legs at positions corresponding to the ratchet gears above the first leg; a second top block is rotatably connected to each of the second fixing rods; and a magnet block is fixedly connected to each of the first legs at positions corresponding to the first fixing rods above the first leg.

[0008] In one embodiment of the present invention, a sliding rod is fixedly connected to the lower end of the second top block; the first support leg is provided with an arc-shaped groove at the position corresponding to the sliding rod, and the sliding rod is slidably connected in the arc-shaped groove; when the sliding rod is located at the upper end of the arc-shaped groove, the second top block is perpendicular to the first top block.

[0009] In one embodiment of the present invention, the frame body has a sliding hole at the position corresponding to the straight groove; an L-shaped insert rod is slidably connected in the sliding hole; a cut is provided at the top of the sliding hole, and the cut is arranged at a 45° angle to the side of the frame body.

[0010] In one embodiment of the present invention, the inner sidewall of the frame is fixedly connected with symmetrically arranged second shafts; hollow tubes are rotatably connected to each of the second shafts, and the outer surfaces of the hollow tubes are in contact with the coils.

[0011] In one embodiment of the present invention, a polygonal hole is provided at one end of the spool; a hand crank is provided on the outside of the spool, and a plug corresponding to the polygonal hole is fixedly connected to it, and the hand crank is inserted into the spool in cooperation with the plug and the polygonal hole.

[0012] In one embodiment of the present invention, the straight slot is opened on the frame, and the center of the other end of the straight slot does not coincide with the center of the frame.

[0013] In one embodiment of the present invention, the first leg, the second leg, and the third leg form an isosceles right triangle with the first leg as the vertex and the second leg and the third leg as the base angles, and are fixedly connected to the frame.

[0014] In one embodiment of the present invention, the grip is fixed between the middle part and the outer end of the second leg; the outer end of the second leg is in the shape of a barb and is arranged perpendicular to the straight groove.

[0015] In one embodiment of the present invention, the shaft is fixed with anti-slip texture at the middle.

[0016] The technical solution of the present invention has the following advantages compared with the prior art:

[0017] This invention discloses a cable laying device. The device includes two states: before and after fixing the cable reel. Before fixing the reel, the first and second rollers contact the ground, with the straight groove parallel to the ground. The reel can be rolled directly until the central shafts at both ends of the reel are engaged in the corresponding straight grooves, or the device can be moved to engage the straight grooves on the corresponding central shafts at both ends of the reel. After fixing the reel, the first roller and the second leg contact the ground, and the straight groove is now perpendicular to the ground. The reel, under its own weight, is located at the end of the straight groove. During the state transition, the reel rotates 90° with the frame, remaining engaged in the straight groove, and the reel changes from being in contact with the ground to being suspended in the air. Cable laying can then be performed. Compared to existing technologies, this device is easy to move, applicable to many scenarios, and convenient to operate. Pulling the cable is also easier after the reel is suspended in the air.

[0018] The present invention provides a cable laying device. In order to fix the frame during cable laying and prevent the frame from being immobilized, the second top block has two states: before the frame rotates and after the frame rotates. Before the frame rotates, the second top block hangs down under the action of gravity and does not interfere with the first top block and the ratchet, and the frame can still move forward. After the frame rotates, that is, after the cable reel is fixed, the second top block hangs down under the action of gravity and makes perpendicular contact with the first top block, restricting the movement of the first top block. At this time, with the cooperation of the first top block and the second top block, the ratchet is locked and cannot rotate in two directions, thus achieving the purpose of automatically fixing the frame.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0030] Please see Figure 1 - Figure 8 This invention provides a cable laying device, including a frame 1; symmetrically arranged straight slots 2 are provided on the frame 1; a cable reel 3 is rotatably connected within the straight slots 2; symmetrically arranged first legs 4 are fixed to one side of the bottom of the frame 1; symmetrically arranged third legs 6 are fixed to the other side of the bottom of the frame 1; symmetrically arranged second legs 5 are fixed to the top of the frame 1 corresponding to the positions of the first legs 4; a first roller 7 is rotatably connected to the inner side of the first legs 4; a second roller 8 is rotatably connected to the inner side of the third legs 6; a handle 16 is fixed between the second legs 5; a limiting component is fixed between the first rollers 7, and the limiting component is used to restrict the rolling of the first rollers 7. To achieve the effect of conveniently fixing the cable reel 3 and improving the stability of the device, in specific use, the device includes two states: before and after fixing the cable reel 3.

[0031] Before fixing the wire reel 3, first use the first roller 7 and the second roller 8 to contact the ground, with the straight groove 2 parallel to the ground. At this time, the wire reel 3 can be rolled directly until the central shafts at both ends of the wire reel 3 are inserted into the corresponding straight grooves 2, or the device can be moved to insert the straight grooves 2 onto the corresponding central shafts at both ends of the wire reel 3.

[0032] After the reel 3 is fixed, the first roller 7 and the second support leg 5 contact the ground. The straight groove 2 is then perpendicular to the ground, and the reel 3 is located at the end of the straight groove 2 under its own weight. The process of changing the state of the device from before the reel 3 is fixed to after the reel 3 is fixed is as follows: After the operator inserts the central shafts at both ends of the reel 3 into the straight groove 2, he holds the handle 16 with both hands, steps on the limiting component with one foot, and then applies a downward force to the handle 16, causing the frame 1 to rotate about 45°. At this time, the force is relatively low. The device achieves an easily controllable balance. The foot holding the limit component is removed, and then both hands continue to apply force until the frame 1 rotates 90°, bringing the second leg 5 into contact with the ground. During this process, the cable reel 3 remains locked on the straight slot 2 as the frame 1 rotates 90°, and the cable reel 3 changes from being in contact with the ground to being suspended in the air. At this point, cable can be laid out from the cable reel 3. Compared to existing technologies, this device is easy to move, applicable to many scenarios, and convenient to operate. Pulling out the cable is also convenient after the cable reel 3 is suspended in the air.

[0033] It is worth noting here that the above positional relationships are all based on... Figure 1 and Figure 2 The state is described.

[0034] Furthermore, such as Figure 1 , Figure 3 and Figure 5As shown, the limiting assembly includes a first shaft 9; ratchet gears 91 are fixedly connected to both ends of the first shaft 9 at positions corresponding to the inner sides of the first leg 4; a first fixing rod 92 is fixedly connected to the first leg 4 at a position above the ratchet gears 91; a first top block 93 is rotatably connected to each of the first fixing rods 92; a second fixing rod 94 is fixedly connected to the first leg 4 at a position above the ratchet gears 91; a second top block 95 is rotatably connected to each of the second fixing rods 94; and a magnet block 98 is fixedly connected to the first leg 4 at a position above the first fixing rod 92. To facilitate the switching between the two states of the equipment, during the switching process, the operator steps on the first shaft 9 to fix the bottom of the frame 1, allowing the operator to apply force using the lever principle. Simultaneously, to prevent the frame 1 from moving backward and posing a hazard to operators behind, the first top block 93 engages with the ratchet 91 to restrict the rotation of the first shaft 9. In this state, the equipment can only move forward and will not slide backward to avoid hazard to operators. If backward movement is required, the first top block 93 can be attracted by the magnet 98, releasing the engagement between the ratchet 91 and the first top block 93. This design allows for better control of the frame during line laying. 1. To fix and prevent the frame 1 from being immobilized, before the frame 1 rotates, the second top block 95 hangs down under the action of gravity, which will not interfere with the first top block 93 and the ratchet 91. The frame 1 can still move forward. After the frame 1 rotates, that is, after the coil 3 is fixed, the second top block 95 hangs down under the action of gravity. The second top block 95 and the first top block 93 are in perpendicular contact, forming a triangular abutment relationship, which obstructs the deflection path of the first top block 93. At this time, the movement of the first top block 93 is restricted. With the cooperation of the first top block 93 and the second top block 95, the ratchet 91 is locked and cannot rotate in two directions, thus achieving the purpose of automatically fixing the frame 1.

[0035] Furthermore, such as Figure 3 and Figure 5 As shown, a sliding rod 96 is fixedly connected to the lower end of the second top block 95; the first support leg 4 has an arc-shaped groove 97 at the position corresponding to the sliding rod 96, and the sliding rod 96 is slidably connected within the arc-shaped groove 97; when the sliding rod 96 is located at the upper end of the arc-shaped groove 97, the second top block 95 is perpendicular to the first top block 93. In order to limit the position of the second top block 95 and prevent the second top block 95 from failing to cooperate with the first top block 93 to lock the ratchet 91 when the wire reel 3 is fixedly laid out, the sliding rod 96 cooperates with the arc-shaped groove 97. After the equipment is rotated 90° as a whole, the second top block 95 can deflect towards the first top block 93 by its own weight, in conjunction with the sliding rod 96 and the arc-shaped groove 97. This allows the first top block 93 and the second top block 95 to form a triangular abutment relationship under the action of gravity, thereby indirectly achieving the effect of locking the ratchet 91.

[0036] Furthermore, such as Figure 6As shown, the frame 1 has a sliding hole 11 corresponding to the position of the straight slot 2; an L-shaped insert rod 13 is slidably connected in the sliding hole 11; a cut 12 is opened at the top of the sliding hole 11, and the cut 12 is arranged at a 45° angle to the side of the frame 1. In order to limit the position of the coil 3 and prevent the coil 3 from falling off when the operator rotates the angle of the frame 1, a sliding hole 11 is opened on the straight slot 2. The L-shaped insert rod 13 hangs down at the bottom of the sliding hole 11 by gravity. The bottom of the L-shaped insert rod 13 can restrict the coil 3 in the straight slot 2. When it is necessary to remove the coil 3, the end of the L-shaped insert rod 13 can be hung at the cut 12 to avoid the L-shaped insert rod 13 from blocking the sliding hole 11 due to gravity. Setting the cut 12 at a 45° angle to the side of the frame 1 makes it convenient for the palm to control the point of action on the L-shaped insert rod 13.

[0037] Furthermore, such as Figure 6 As shown, symmetrically arranged second shafts 14 are fixed to the inner wall of the frame 1; hollow tubes 15 are rotatably connected to each of the second shafts 14, and the outer surfaces of the hollow tubes 15 are in contact with the cable reel 3. In order to support the cable reel 3 without hindering cable laying, the second shafts 14 are provided inside the frame 1. When the cable reel 3 is fixed for laying, the hollow tubes 15 support the cable reel 3 and support the central shafts at both ends of the cable reel 3. When laying, the cable reel 3 will rotate. At this time, the rolling of the hollow tubes 15 and the cable reel 3 changes the static friction between the central shafts at both ends of the cable reel 3 and the straight groove 2 to the rolling friction between the bottom of the cable reel 3 and the hollow tubes 15. This can achieve low-resistance cable laying of the cable reel 3 and avoid the static friction generated by the close contact of the central shafts at both ends of the cable reel 3 with the straight groove 2, which would hinder the cable laying of the cable reel 3.

[0038] Furthermore, such as Figure 7 As shown, a polygonal hole 31 is provided at one end of the cable reel 3; a hand crank 32 is provided on the outside of the cable reel 3, and a corresponding plug 33 is fixed to the hand crank 32, and the hand crank 32 is inserted into the cable reel 3 with the cooperation of the plug 33 and the polygonal hole 31. In order to facilitate manual intervention in the cable laying effect, a polygonal hole 31 is provided at one end of the cable reel 3, and a corresponding plug 33 is fixed to the hand crank 32. By inserting the plug 33 into the polygonal hole 31, the operator can apply force to the hand crank 32 to drive the cable reel 3 to rotate, thereby achieving the purpose of intervening in the cable laying.

[0039] Furthermore, such as Figure 1 and Figure 8As shown, the straight groove 2 is opened on the frame 1, and the center of the other end of the straight groove 2 does not coincide with the center of the frame 1. In order to achieve the effect of the spool 3 being suspended after it is fixed, the center of the other end of the straight groove 2 is not coincided with the center of the frame 1. As the spool 3 rotates with the frame 1, its height is raised, so that the bottom of the spool 3 is lifted off the ground.

[0040] Furthermore, such as Figure 8 As shown, the first leg 4, the second leg 5, and the third leg 6 form an isosceles right triangle with the first leg 4 as the apex and the second leg 5 and the third leg 6 as the base angles, and are fixed to the frame 1. To ensure high stability of the frame 1 before and after rotation and to facilitate the installation and fixation of the reel 3, the first leg 4, the second leg 5, and the third leg 6 are arranged in the position of an isosceles right triangle with the first leg 4 as the apex and the second leg 5 and the third leg 6 as the base angles. During rotation, they all rotate around the first leg 4 as the center of rotation, facilitating operation.

[0041] Furthermore, such as Figure 1 and Figure 8 As shown, the grip 16 is fixed between the middle and outer ends of the second leg 5; the outer end of the second leg 5 is in the shape of a barb and is arranged perpendicular to the straight groove 2. In order to further improve the stability of the frame 1 and facilitate the operation of the grip 16 by the operator, the grip 16 is fixed between the middle and outer ends of the second leg 5 to prevent the grip 16 from pressing the palm to the ground after the frame 1 rotates. The outer end of the second leg 5 is in the shape of a barb and is arranged perpendicular to the straight groove 2, which can increase the contact area between the second leg 5 and the ground. Placing stones or other weights at the barb can increase stability.

[0042] Furthermore, such as Figure 2 As shown, the shaft has anti-slip grooves 10 fixed in the middle. This prevents workers from slipping when stepping on the second shaft 14, thus improving safety.

[0043] Working principle:

[0044] The device includes two states: before and after fixing the wire reel 3.

[0045] Before fixing the wire reel 3, the first roller 7 and the second roller 8 first contact the ground, and the straight groove 2 is parallel to the ground. At this time, the wire reel 3 can be rolled directly until the central shafts at both ends of the wire reel 3 are inserted into the corresponding straight grooves 2, or the device can be moved to lock the straight grooves 2 onto the corresponding central shafts at both ends of the wire reel 3. After fixing the wire reel 3, the first roller 7 and the second support leg 5 contact the ground. At this time, the straight groove 2 is perpendicular to the ground, and the wire reel 3 is located at the end of the straight groove 2 under its own weight.

[0046] The process of the device transitioning from the state before and after the cable reel 3 is fixed is as follows: After the operator inserts the central shafts at both ends of the cable reel 3 into the straight groove 2, they hold the handle 16 with both hands, step on the limiting component with one foot, and then apply a downward force to the handle 16, causing the frame 1 to rotate about 45°. At this point, the force is in a relatively easy-to-control equilibrium state. The foot stepping on the limiting component is then removed, and the force is continued to be applied with both hands until the frame 1 rotates 90°, reaching the state where the second leg 5 is in contact with the ground.

[0047] During this process, the reel 3 rotates 90° with the frame 1 and remains locked on the straight slot 2. The reel 3 changes from being in contact with the ground to being suspended in the air. At this time, the reel 3 can be used for cable laying. Compared with the existing technology, this device is easy to move, applicable to many scenarios, and easy to operate. After the reel 3 is suspended in the air, it is more convenient to pull out the cable.

[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
