Description

Technical Field

[0001] The utility model relates to a bending tool, more specifically, it relates to a bending tool for cable laying. Background Art

[0002] In residential projects, the reserved channels are often small, and the operating space for workers is also limited. The cables need to be bent and shaped at the bends to avoid wear and tear caused by friction between the cables and the bridge or the ground. However, in the actual working environment, the bending angle of the reserved area cannot be fixed, and it is difficult for workers to bend the cables to the appropriate angle in advance. This limited work link adds considerable difficulty to the workers' construction, and the installation quality is also difficult to control. Whether the cable is bent manually or by an electric hoist, if the cable cross-sectional area or hardness is large, it is difficult to install and the force is not easy to control. If it cannot be bent into shape in one time, repeated bending may damage the cable. Therefore, a bending tool for cable laying is needed, which can bend the cable according to the actual reserved bending angle.

[0003] In view of the above reasons, how to perform qualitative bending operations on the cable according to the actual reserved bending angle is exactly the problem considered in this application. Utility Model Content

[0004] In view of the deficiencies in the prior art, a bending tool for cable laying is provided, which can perform qualitative bending operations on cables according to an actually reserved bending angle.

[0005] To achieve the above-mentioned purpose, the following technical solution is provided: a bending tool for cable laying, comprising a frame, on which are mounted two bending components and two movable components symmetrically arranged at both ends of the frame, the bending components being connected to a fixing component for fixing the cable, and two lubrication components respectively arranged under the corresponding bending components and used for releasing lubricating liquid are also installed at the bottom of the frame, the bending component comprising a rotating wheel for bending the cable, the rotating wheel being fixedly connected to a transmission shaft rotatably connected to the frame, and the movable component comprising a first roller which is detachably connected to the transmission shaft and respectively arranged at the upper and lower ends of the frame.

[0006] In summary, the above technical solution has the following beneficial effects: since the channel is usually made of cement, the inner wall is usually rough, and the first roller can keep the movement of the frame stable by friction with the rough inner wall. When the frame needs to move, traction ropes can be connected to both sides of the frame respectively, and the traction ropes are pulled by the motor to realize the movement of the frame. Since there are two moving components, when driving the frame to move, the two traction ropes can be pulled to set a differential speed so that the frame can turn.

[0007] When the rack moves, since the first roller always contacts the inner wall of the channel, the rack can always move along the bending angle of the channel, so that the bending angle of the cable can be made consistent with the bending angle of the channel by bending and shaping the cable through the bending component, and when there are a large number of cables arranged flat, the position of the cables can be fixed by the fixing component, so that multiple cables can be bent at the same time;

[0008] When the cable extends into the channel, it will be slightly bent first. If it is not bent and shaped, it will return to its original shape by itself. On the one hand, the cable will rub against the rough inner wall when it returns to its original shape, causing damage. On the other hand, when the cable returns to its original shape by itself, multiple cables may be intertwined, which will cause trouble for subsequent cable maintenance. Therefore, it is necessary to use fixed components to make multiple cables appear nearly flat. In addition, the rack cannot directly shape the cable after one movement, so it needs to be moved back and forth multiple times to eliminate the internal stress of the cable and prevent the cable from returning to its original state.

[0009] The lubrication component can continuously release lubricating liquid at the bottom, which can reduce the friction between the rack and the channel at the bottom. On the other hand, multiple cables will naturally form an arch after being laid flat and bent. After the two ends of the arch are bent and shaped, they will still generate friction when they contact the channel. The lubricating liquid released by the lubrication component can also reduce the friction between the cables at both ends of the arch and the channel through the lubricating liquid, reducing the possibility of damage due to friction.

[0010] The cables at both ends can speed up the overall bending speed by squeezing the cables in the middle. Therefore, the cables at both ends receive greater pressure. The rotating wheel not only speeds up the bending of the cables, but also reduces the friction force received by the cables at both ends, thus preventing the cables at both ends from being worn.

[0011] The utility model realizes the bending of the cable by setting two moving components, and the first roller is always in contact with the inner wall of the channel, so that the bending angle of the cable is consistent with the bending angle of the channel. In addition, a rotating wheel is set to assist the cable bending, so as to achieve the purpose of bending the cable qualitatively according to the actual reserved bending angle.

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] Reference Figure 1-5 As shown, a bending tool for cable laying includes a frame 1, on which are mounted two bending components 2 and two moving components 3 symmetrically arranged at both ends of the frame 1, the bending components 2 are connected to a fixing component 4 for fixing the cable, and the bottom of the frame 1 is also equipped with two lubricating components 5 respectively arranged below the corresponding bending components 2 and used for releasing lubricating liquid, the bending component 2 includes a rotating wheel 21 for bending the cable, the rotating wheel 21 is fixedly connected to a transmission shaft 22 rotatably connected to the frame 1, and the moving component 3 includes first rollers 31 detachably connected to the transmission shaft 22 and respectively arranged at the upper and lower ends of the frame 1;

[0026] Since the channel is usually made of cement, the inner wall is usually rough. The first roller 31 can keep the movement of the frame 1 stable by friction with the rough inner wall. When the frame 1 needs to move, traction ropes can be connected to both sides of the frame 1 respectively, and the traction ropes are pulled by the motor to realize the movement of the frame 1. Since there are two moving components 3, when driving the frame 1 to move, the two traction ropes can be pulled to set a differential speed so that the frame 1 can turn.

[0027] When the rack 1 moves, since the first roller 31 always contacts the inner wall of the channel, the rack 1 can always move along the bending angle of the channel, so that the bending angle of the cable can be made consistent with the bending angle of the channel by bending and shaping the cable through the bending component 2, and when there are a large number of cables arranged flat, the position of the cables can be fixed by the fixing component 4, so that multiple cables can be bent at the same time;

[0028] When the cable extends into the channel, it will be slightly bent first. If it is not bent and shaped, it will return to its original shape by itself. On the one hand, the cable will rub against the rough inner wall when it returns to its original shape, thereby causing damage. On the other hand, when the cable returns to its original shape by itself, multiple cables may be intertwined, which will cause trouble for subsequent cable maintenance. Therefore, it is necessary to use a fixing component 4 to make multiple cables appear nearly flat, and the rack 1 cannot directly shape the cable after one movement, so it needs to be moved back and forth multiple times to eliminate the internal stress of the cable and prevent the cable from returning to its original state.

[0029] The lubricating component 5 can continuously release lubricating liquid at the bottom, which can reduce the friction between the rack 1 and the channel at the bottom. On the other hand, multiple cables will naturally form an arch after being laid flat and bent. After the two ends of the arch are bent and shaped, friction will still occur after contacting the channel. The lubricating liquid released by the lubricating component 5 can also reduce the friction between the cables at both ends of the arch and the channel through the lubricating liquid, thereby reducing the possibility of damage due to friction.

[0030] The cables at both ends can accelerate the speed of overall bending by squeezing the cables in the middle, so the cables at both ends receive greater pressure. The rotating wheel 21 not only accelerates the bending of the cables by rotating, but also reduces the friction force received by the cables at both ends, thereby preventing the cables at both ends from being worn.

[0031] The utility model realizes the bending of the cable by setting two moving components 3, and the first roller 31 always contacts the inner wall of the channel, so that the bending angle of the cable is consistent with the bending angle of the channel. In addition, a rotating wheel 21 is set to assist the cable bending, so as to achieve the purpose of bending the cable qualitatively according to the actual reserved bending angle.

[0032] Furthermore, the moving assembly 3 further includes a partition plate 32 rotatably connected to the transmission shaft 22 and rotatably connected to the first roller 31, and a first gasket 33 rotatably connected to the rotating wheel 21 is fixedly connected to the side of the partition plate 32 facing the rotating wheel 21;

[0033] The partition 32 is connected to the two transmission shafts 22 at the same time, which can stabilize the frame 1. Since screws are required to install the partition 32, in order to prevent the screws from affecting the rotation of the rotating wheel 21, a first gasket 33 is provided to separate the partition 32 from the rotating wheel 21.

[0034] Furthermore, the rotating wheel 21 is also provided with an annular groove 23 for accommodating the cable and arranged along the rolling direction of the rotating wheel 21, and the cross section of the annular groove 23 is semicircular;

[0035] In order to prevent the cable from sliding when being bent, an annular groove 23 is provided for accommodating the cable, and the cross section of the annular groove 23 is semicircular, so as to facilitate fixing the position of the cable together with the fixing component 4 .

[0036] Further, the fixing assembly 4 includes a plurality of upper splicing pieces 41 and a plurality of lower splicing pieces 42. The upper splicing piece 41 is symmetrically provided with two first empty grooves 411 with a cross section of a quarter circle at the bottom, and the lower splicing piece 42 is symmetrically provided with two second empty grooves 421 with a cross section of a quarter circle at the top. The cross-sectional circle radius of the first empty groove 411, the cross-sectional circle radius of the second empty groove 421 and the cross-sectional circle radius of the annular groove 23 are consistent.

[0037] A plurality of first positioning blocks 34 are fixedly connected to one end of the partition plate 32 facing the upper assembly piece 41, a first positioning groove 412 for accommodating the first positioning blocks 34 is provided at the top of the upper assembly piece 41, a plurality of second positioning blocks 11 and a second gasket 12 for raising the lower assembly piece 42 are fixedly connected to one end of the frame 1 facing the lower assembly piece 42, and a second positioning groove 422 for accommodating the second positioning block 11 is provided at the bottom of the lower assembly piece 42;

[0038] The first positioning block 34 cooperates with the corresponding first positioning groove 412 to prevent the upper assembly 41 from moving in the horizontal direction, and under the action of the partition 32 and the cable, the lower assembly 42 is prevented from moving in the horizontal direction. The second positioning block 11 cooperates with the corresponding second positioning groove 422 in the same manner.

[0039] The first empty groove 411 of an upper splicing piece 41 and the second empty groove 421 of a lower splicing piece 42 can form a complete accommodating channel with the annular groove 23 of the rotating wheel 21. Similarly, the first empty grooves 411 of the two upper splicing pieces 41 and the second empty grooves 421 of the two lower splicing pieces 42 can also form a complete accommodating channel. The cable passes through the accommodating channel, and when the frame 1 turns, the inner wall of the accommodating channel contacts the cable, so that the cable can bend, thereby realizing the bending and shaping operation of the cable.

[0040] Furthermore, two symmetrically arranged first fixing grooves 413 are further arranged in the upper splicing piece 41, and the upper splicing piece 41 is further fixedly connected to two first fixing pieces 414 which are respectively arranged in the corresponding first fixing grooves 413 and are symmetrically arranged. The cross section of the first fixing piece 414 is "L"-shaped, and the first fixing piece 414 is detachably connected to a first connecting piece 415 which is detachably connected to another first fixing piece 414. The height of the first fixing groove 413 is greater than the sum of the height of the first fixing piece 414 and the height of the first connecting piece 415.

[0041] The lower assembly piece 42 is further provided with two symmetrically arranged second fixing grooves 423, and the lower assembly piece 42 is further fixedly connected with two second fixing pieces 424 which are respectively arranged in the corresponding second fixing grooves 423 and are symmetrically arranged. The cross section of the second fixing piece 424 is "L"-shaped. The second fixing piece 424 is detachably connected with a second connecting piece 425 which is detachably connected with another second fixing piece 424. The height of the second fixing groove 423 is greater than the sum of the height of the second fixing piece 424 and the height of the second connecting piece 425.

[0042] The two upper splicing pieces 41 are relatively fixed by two first fixing pieces 414 and one first connecting piece 415 to prevent the upper splicing pieces 41 from falling apart. Since the first connecting piece 415 is detachably connected to the first fixing piece 414 by plugging in the vertical direction, and the upper splicing piece 41 has been restricted from moving in the vertical direction, the upper splicing piece 41 can be prevented from detaching. The same is true for preventing the lower splicing piece 42 from detaching.

[0043] Furthermore, the lubrication assembly 5 includes a storage compartment 51 detachably connected to the frame 1 and used to store lubricating oil, a plurality of liquid outlets 52 and a ball seat 53 disposed at the liquid outlet are provided at the bottom of the storage compartment, and a ball 54 is placed in the ball seat 53;

[0044] The ball 54 can bring lubricating oil with a certain viscosity when rolling, and the lubricating component 5 cannot flow out from the liquid outlet due to its own tension when the ball 54 does not roll, so the lubricating oil is released only when the cable bending and shaping operation is performed, thereby preventing the lubricating oil from being wasted.

[0045] Furthermore, a brush 55 is fixedly connected to the bottom of the storage compartment 51 .

[0046] Furthermore, the storage compartment 51 is cylindrical and the axial center of the storage compartment 51 is arranged on the same line as the axial center of the transmission shaft 22. The storage compartment 51 is also rotatably connected to a second roller 56, and the shape of the second roller 56 is the same as that of the first roller 31.

[0047] The function of the second roller 56 is similar to that of the first roller 31 , and the second roller 56 is arranged below the frame 1 , while the first roller 31 is arranged above the frame 1 , so as to further stabilize the movement of the frame 1 .

[0048] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
