Description

Technical Field

[0001] The invention relates to the field of electric power, and in particular to a cable corner laying assistant. Background Art

[0002] In the power industry, laying cables in cable trenches is a common operation in the early stages and during maintenance. Due to the complex conditions of the cable trenches and the large number of corners, the conventional method of operation is to assign at least one person to assist in laying the cables at each corner of the trench to avoid the cables being worn or broken at the corners. This results in high labor costs and low efficiency in laying cables.

[0003] Patent document CN201720546161.X discloses a portable special device for laying optical cables, including an angle iron with an opening facing the cable support arm, the angle iron including a vertical surface and a horizontal surface arranged on the top of the vertical surface, an axle seat is fixedly arranged on the vertical surface of the angle iron away from the cable support arm surface, two axle seat holes are vertically arranged on the axle seat, and the two axle seat holes are arranged along the length direction of the angle iron, the device also includes two rotating shafts, the bottom ends of the two rotating shafts are respectively arranged in the axle seat holes through bearings, the top ends of the two rotating shafts are respectively provided with axial holes, an axle cover plate is arranged between the two rotating shafts, the axle cover plate includes a flat plate and a pin shaft arranged under the flat plate and adapted to the axle hole, and the pin shaft is perpendicular to the flat plate; since the device has two rotating shafts at the corner, the optical cable passes between the two rotating shafts, the optical cable will not be worn or squeezed off, and there is no need to equip cable laying personnel at the corner, which can improve the laying efficiency and save costs, and it has a simple structure, low cost and easy installation.

[0004] The above scheme has the following problems: 1. When the cable is laid and encounters multiple reverse cable trench corners, the cable only bypasses the two shafts alternately, and it is easy to slide to the connection between the shaft and the angle iron, resulting in locking;

[0005] 2. After the cable is laid, the separation of the cable and the entire device requires the removal of the shaft cover. This process requires the separation of the shaft bearing from the shaft cover. In the machinery industry, it is not easy to separate the bearing and the shaft. Moreover, frequent separation of the bearing and the shaft will affect the service life of the bearing and the shaft.

[0006] 3. The corner of the cable trench is generally a 90° corner, but the straight angle iron used in the above scheme is not convenient to fix and has poor ability to adapt to corners.

[0007] 4. When the cable is released quickly, the two rotating shafts will shake obviously, and the shaking amplitude is proportional to the cable release speed. If it is not controlled, it will cause damage to the entire device when the cable is released quickly. Summary of the invention

[0008] In view of the above-mentioned technical problems, the present invention provides a cable corner laying assistant.

[0009] In order to achieve the above object, the technical solution adopted by the present invention is:

[0010] A cable corner laying assistant, comprising:

[0011] Two unit bottom plates, which can be detachably matched to allow placement on both sides of the cable corner, and can be detachably connected to the cable support wall;

[0012] Two shaft seats are detachably connected to the upper surfaces of the two unit bottom plates, and bearings are arranged in the shaft seats;

[0013] Two unit top plates, which are detachably matched, are provided with shaft holes at the bearings corresponding to the two shaft seats, and bearings are provided in the shaft holes;

[0014] Two rotating shafts, both of which are provided with pulleys in the middle, and the two rotating shafts are respectively overfitted in the corresponding shaft seat bearings and the bearings of the unit top plate;

[0015] The buffer is detachably connected between the two unit top plates and the cable corner wall to absorb the shaking energy of the two rotating shafts when the cable is released.

[0016] Furthermore, the above-mentioned cable corner laying assistant has two unit bottom plates and two unit top plates respectively provided with a first through hole near the joint, and also includes a connecting piece, the connecting piece is hexahedral, and a middle part is provided with an embedding groove that can be snapped into the joint of the two unit bottom plates or the two unit top plates, and the connecting piece is provided with a second through hole corresponding to the first through hole. After the connecting piece is snapped into the joint of the two unit bottom plates or the two unit top plates, the two unit bottom plates or the two unit top plates and the connecting piece are detachably connected by passing bolts through the first through hole and the second through hole.

[0017] Furthermore, in the above-mentioned cable corner laying assistant, the buffer part includes a first connecting block, a second connecting block, a telescopic spring and a wall connecting part, wherein the telescopic spring is arranged between the first connecting block and the second connecting block, the first connecting block is detachably connected to the connecting part of the two unit top plates, and the wall connecting part is hinged to the hinge seat on the corner wall of the cable trench through a hinge shaft.

[0018] Furthermore, in the above-mentioned cable corner laying assistant, a third through hole is provided on the unit bottom plate, and a corresponding fourth through hole is provided on the shaft seat, and a detachable connection between the shaft seat and the unit bottom plate is achieved by passing bolts through the third through hole and the fourth through hole.

[0019] Furthermore, in the above-mentioned cable corner laying assistant, the unit bottom plate is provided with a connecting hole, and a fastener is inserted into the connecting hole to realize a detachable connection between the two unit bottom plates and the cable support wall.

[0020] Furthermore, in the above-mentioned cable corner laying assistant, the unit bottom plate and the unit top plate are linear, arc-shaped or irregular in shape.

[0021] Furthermore, in the above-mentioned cable corner laying assistant, the unit bottom plate and the unit top plate are arc-shaped.

[0022] Compared with the prior art, the beneficial effects of the solution provided by the present embodiment are:

[0023] 1. Pulleys are arranged on the two rotating shafts. The cables alternately pass through the pulley grooves of the two rotating shafts. The pulley grooves limit the cables. Therefore, when the cables encounter multiple reverse cable trench corners during laying, the cables will not slide down to the connection between the rotating shaft and the unit bottom plate, thus avoiding the problem of locking the cables and the rotating shafts and improving the smoothness of cable laying.

[0024] 2. After the cable is laid, you only need to dismantle the connection between the buffer and the corner wall of the cable trench and the connection between the two unit top plates, and then rotate the shaft to stagger the two unit top plates at a certain angle, and then you can take the cable out from between the two shafts. There is no need to separate the shaft and the bearings in the shaft hole of the unit top plate, which improves the efficiency of taking out the cable and prolongs the service life of the shaft and the bearings in the shaft hole of the unit top plate;

[0025] 3. The unit bottom plate and unit top plate are designed to be arc-shaped, which is not only convenient for fixing with the cable support wall, but also improves the applicability to different cable trench corners;

[0026] 4. The buffer can absorb the energy of the shaft shaking when the cable is released quickly, so that the cable release operation can be carried out quickly while ensuring the stability of the device, thereby improving the cable release efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] Embodiment 1:

[0032] like Figure 1 and Figure 2 As shown, the present invention provides a cable corner laying assistant, comprising:

[0033] Two unit bottom plates 1 can be placed on both sides of the cable corner after being detachably matched, and can be detachably connected to the cable support wall (not shown). Specifically, a connection hole 14 is provided on the unit bottom plate 1, and a fastener (not shown) is inserted into the connection hole 14 to realize the detachable connection between the two unit bottom plates 1 and the cable support wall;

[0034] Two shaft seats 2 are detachably connected to the upper surfaces of the two unit bottom plates 1, respectively. A bearing 3 is arranged in the shaft seat 2. Specifically, a third through hole 12 is arranged on the unit bottom plate 1, and a corresponding fourth through hole 13 is arranged on the shaft seat 2. The detachable connection between the shaft seat 2 and the unit bottom plate 1 is realized by passing a bolt 11 through the third through hole 12 and the fourth through hole 13;

[0035] Two unit top plates 4, which are detachably matched, are provided with shaft holes 5 at the bearings 3 corresponding to the two shaft seats 2, and the shaft holes 5 are provided with bearings 3;

[0036] Two rotating shafts 6, both of which are provided with pulleys 7 in the middle, and the two rotating shafts 6 are respectively overfitted in the corresponding bearings 3 of the shaft seat 2 and the bearings 3 of the unit top plate 4, so that two unit bottom plates 1 are fixed on the cable support wall, and the two unit top plates 4 are rotated on the two rotating shafts 6, and the unit top plates 4 are not connected to the cable support wall and the corner wall of the cable trench;

[0037] The buffer member 8 is detachably connected between the two unit top plates 4 and the cable corner wall, and is used to absorb the shaking energy of the two rotating shafts 6 when the cable is released.

[0038] like Figure 2 As shown, the two unit bottom plates 1 and the two unit top plates 4 are respectively provided with a first through hole 9 near the joint, and also include a connecting member 10. The connecting member 10 is hexahedral, and a mounting groove 10a is provided in the middle portion which can be snapped into the joint of the two unit bottom plates 1 or the two unit top plates 4. The connecting member 10 is provided with a second through hole 10b at the position corresponding to the first through hole 9. After the connecting member 10 is snapped into the joint of the two unit bottom plates 1 or the two unit top plates 4, the two unit bottom plates 1 or the two unit top plates 4 and the connecting member 10 are detachably connected by passing bolts 11 through the first through hole 9 and the second through hole 10b.

[0039] like Figure 2As shown, the buffer member 8 includes a first connecting block 80, a second connecting block 81, a telescopic spring 82 and a wall connecting member 83, wherein the telescopic spring 82 is arranged between the first connecting block 80 and the second connecting block 81, and the first connecting block 80 is detachably connected to the connecting member 10 of the two unit top plates 4, that is, the first connecting block 80 is detachably connected to the two unit top plates 4. Since there are many detachable connection methods, the connection between the first connecting block 80 and the two unit top plates 4 here also belongs to a conventional method, which is not specifically listed here. The wall connecting member 83 is hinged to the hinge seat (not shown) on the cable corner wall through a hinge shaft; in the fast During the rapid cable-releasing operation, since the cable moves rapidly on the pulleys 7 of the two rotating shafts 6, the two unit bottom plates 1 are fixed on the cable support wall, playing a supporting and positioning role for the entire cable-releasing auxiliary device, and the two unit top plates 4 are excessively fitted on the two rotating shafts 6. During the rapid cable-releasing operation, the two unit top plates 4 and the two rotating shafts 6 have a periodic shaking motion with a certain amplitude toward and away from the corner wall of the cable trench. Since one side of the two unit top plates 4 is connected to the corner wall of the cable trench through the buffer member 8, at this time, when the two unit top plates 4 and the upper ends of the two rotating shafts 6 are shaking toward and away from the corner wall of the cable trench, the telescopic spring 82 absorbs the shaking energy of the two unit top plates 4 and the two rotating shafts 6 to prevent the upper ends of the two unit top plates 4 and the two rotating shafts 6 from approaching and moving away from the corner wall of the cable trench, thereby reducing the shaking amplitude of the two unit top plates 4 and the two rotating shafts 6, thereby improving the operational stability of the rapid cable-releasing operation and reducing the risk of the cable-releasing auxiliary device being damaged during the rapid cable-releasing operation.

[0040] like Figure 2 As shown, the unit bottom plate 1 and the unit top plate 4 can be set in a straight line, arc or irregular shape. In this solution, an arc is specifically adopted. The arc-shaped unit bottom plate 1 is not only convenient for fixing to the cable support wall, but also improves the applicability to different cable trench corners.

[0041] Directions:

[0042] 1. First, take out two unit bottom plates 1, use the connecting piece 10 to align the two unit bottom plates 1 and connect them, fix the two unit bottom plates 1 on the cable support arm at the corner of the cable trench through fasteners, and then use the bolts 11 to fix the shaft seat 2 on the unit bottom plate 1, then take out two rotating shafts 6 and set them in the bearings 3 of the shaft seat 2, take out two unit top plates 4, use the connecting piece 10 to align the two unit top plates 4 again, and then over-fit the other ends of the two rotating shafts 6 into the bearings 3 of the shaft holes 5 of the two unit top plates 4; then connect the first connecting block 80 of the buffer 8 to the connecting piece 10 of the two unit top plates 4, and the wall connecting piece 83 of the buffer 8 is hinged to the hinge seat set on the wall of the corner of the cable trench through the hinge axis;

[0043] 2. When laying, place the cable on the cable drum, and one or more people hold the free end of the cable and move forward along the cable trench. When encountering the corner of the cable trench, alternately pass the cable through the pulley 7 groove of the rotating shaft 6 before and after the corner of the cable trench, and then repeat the above operation;

[0044] 3. After the cable is laid, at each corner of the cable trench, remove the connection between the wall connecting piece 83 at the end of the buffer 8 and the corner wall of the cable trench, then remove the connection between the two unit top plates 4 and the connecting piece 10, then rotate the shaft 6 to stagger the two unit top plates 4 by a certain angle, and then take the cable out from between the two shafts 6, and finally remove the connection between the two unit bottom plates 1 and the cable support wall.
