Description

Technical Field

[0001] This utility model relates to the field of cable construction technology in civil engineering, decoration and electromechanical installation engineering, and in particular to a cable dragging tool, or a cable dragging tool for decoration and installation. Background Technology

[0002] In the field of civil engineering pipeline construction, to maintain the aesthetics of buildings, pipelines are usually laid in concealed locations such as behind walls and under floors. However, in actual construction, due to design changes, engineering repairs, or construction omissions, the internal cables are often not run through the pipeline after it is sealed, or they need to be re-run. Currently, the industry mainly uses the following two construction methods:

[0003] Traditional open-cut repair method: This involves excavating the wall or floor to expose the pre-installed pipe channel (or removing the installed pipe), and then repairing the cable after it has been threaded through. This method not only relies on skilled workers, but also has high construction costs, low efficiency, and difficulty in completely restoring the repaired area, affecting aesthetics and structural integrity.

[0004] The steel rod pulling method involves threading a long steel rod through the pipe, binding the cable, and then dragging it to complete the cable threading. However, this method is only suitable for short-distance pipes. If the pipe is too long, the operation becomes difficult, and the rigid insertion of the steel rod can easily damage the inner wall of the pipe, posing a construction safety hazard.

[0005] Existing technological shortcomings:

[0006] Poor economic efficiency: The excavation and repair method requires repeated construction, and the material and labor costs are high;

[0007] Safety hazard: Improper use of steel rods may cause pipe rupture or personal injury;

[0008] Aesthetically unappealing: Repairs easily leave obvious marks, affecting the overall appearance of the building.

[0009] Therefore, there is an urgent need for an efficient, low-cost, and non-destructive pipeline wiring device and method to overcome the limitations of existing technologies. Utility Model Content

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] The purpose of this invention is to provide a cable dragging tool to solve the problems existing in the prior art. The active component uses magnetic attraction to drive the driven component to move, thereby dragging the cable. This allows the cable to be moved along a specified path without damaging the structure, and has the advantages of high efficiency, low cost and simple operation.

[0039] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] like Figures 1 to 7 As shown, this utility model provides a cable dragging tool, mainly used in decoration and electromechanical installation projects, for dragging cables to complete cable construction. Of course, this utility model does not exclude applications in other areas. The cable dragging tool includes a driven component 1 and an active component 2. The driven component 1 is located on one side of an obstruction, which can be a partition 4 (such as a wall, floor, etc.) or a pipe 5. The driven component 1 includes a first body 11 and a dragging part 12 connected to the first body 11. The first body 11 can be a block, vehicle body, etc. The dragging part 12 is used to connect the cable 3, and the connection can be made by clamping, binding, or other methods. The active component 2 is located on the other side of the obstruction. The active component 2 includes a second body 21 and a drive unit connected to the second body 21. The second body 21 can be a block, a vehicle body, etc. The drive unit is used to drive the second body 21 to move. The drive unit can be a handheld component or an electric drive component. Therefore, the second body 21 can move by manual drive or by its own electric drive component. When the second body 21 moves, it drives the first body 11 to move by magnetic attraction with the first body 11.

[0041] This invention places the active component 2 and the driven component 1 on both sides of the obstruction. The active component 2 and the driven component 1 have a magnetic attraction. When the active component 2 is driven to move, the magnetic attraction can be used to drive the driven component 1 to move, thereby dragging the cable 3 without contacting it. This allows the cable 3 to be moved along a specified path without damaging the structure (here referring to the partition 4 or pipe 5, etc.), which has the advantages of high efficiency, low cost and simple operation.

[0042] The separate design of the driven component 1 and the active component 2 allows for disassembly and assembly, and either the driven component 1 or the active component 2 can be replaced individually to save costs. Due to its small size, it is easy to carry and has strong applicability. Only the active component 2 needs to be controlled to drag the driven component 1 and the cable 3, which does not require professional technicians. It is simple to operate and easy to use, reducing labor costs.

[0043] Because the driven component 1 and the active component 2 can transmit force without contact, cable 3 can be dragged without destroying the existing structure, avoiding secondary repairs, saving costs and improving efficiency. The cable dragging tool can also be used as a dedicated cable pulling tool, which is safe and efficient, improves construction methods, reduces costs, manpower consumption and personnel skill requirements, saves expenses, and improves construction efficiency, construction quality and safety.

[0044] In one implementation, such as Figures 4-6 As shown, the driven component 1 also includes a first traveling wheel 13, which is mounted on the first main body 11. During installation, the first traveling wheel 13 is arranged in a rectangular or triangular pattern. The wheel surface of the first traveling wheel 13 contacts the obstruction, allowing the driven component 1 to roll along one side of the obstruction. The first traveling wheel 13 reduces the frictional resistance between the driven component 1 and the obstruction, making it easier for the driven component 1 to move. It can roll forward quickly in different environments, improving threading efficiency and enabling rapid completion of threading work.

[0045] In one implementation, such as Figure 7 As shown, the active component 2 also includes a second traveling wheel 23, which is installed on the second main body 21. During installation, the second traveling wheel 23 is arranged in a rectangular or triangular pattern. The wheel surface of the second traveling wheel 23 contacts the obstruction, allowing the active component 2 to roll and move on the other side of the obstruction. The second traveling wheel 23 reduces the frictional resistance between the active component 2 and the obstruction, making it easier for the active component 2 to move. It can roll forward quickly in different environments, improving threading efficiency and enabling rapid completion of threading work.

[0046] In one implementation, such as Figure 7As shown, the driving part is a handle 22 provided on the second body 21. The handle 22 extends along the length of the second body 21. The handle 22 is easy for the hand to hold. By holding the handle 22, the position of the second body 21 can be moved manually, thereby driving the first body 11 of the driven component 1 to move, and finally realizing the dragging and moving of the cable 3.

[0047] In one embodiment, the drive unit is a rotation drive mechanism connected to the second traveling wheel 23. The rotation drive mechanism can be a motor, which drives one or more of the second traveling wheels 23 to rotate, thereby driving the second traveling wheels 23 to move. The speed of the motor is controllable, thereby controlling the traveling speed of the second traveling wheels 23. In addition, for easy steering, a steering control mechanism can be provided, which can be remotely operated to conveniently control the direction of movement.

[0048] In one implementation, such as Figures 4-6 As shown, the drag unit 12 includes two support plates 123 and at least one retaining shaft 124. The two support plates 123 are arranged in parallel with a distance between them. The support plates 123 are connected to the tail end of the first main body 11. The retaining shaft 124 is vertically connected between the two support plates 123. The cable 3 can be fixed by wrapping around the retaining shaft 124.

[0049] In one implementation, such as Figure 6 As shown, there are two retaining shafts 124, which are set in parallel with a distance between them. When fixing the cable 3, the cable 3 can be wrapped around the two retaining shafts 124 in a figure-eight shape, which further improves the fixing effect of the cable 3.

[0050] In one implementation, such as Figure 6As shown, the drag section 12 also includes a locking plate 121 and a pin 122. The locking plate 121 is hinged to the end of the support plate 123 near the first body 11, or the locking plate 121 is hinged to the end of the first body 11 near the support plate 123, and the locking plate 121 can rotate about its hinge axis. The pin 122 is connected to the free end of the locking plate 121, for example, by welding. The pin 122 can be a single piece, in which case the pin 122 is connected to the end face of the locking plate 121 and extends to both sides beyond the width of the locking plate 121; or, two pins 122 can be used, with the two pins 122 respectively connected to the two sides of the locking plate 121. The support plate 123 has a U-shaped socket 1231. The size and depth of the socket 1231 match the pin 122. The socket 1231 is located on the rotation path of the pin 122 (the pin 122 rotates with the rotation of the clamping plate 121). The pin 122 can be engaged into the socket 1231, thus securing the clamping plate 121. A clamping area for the cable 3 is formed between the clamping plate 121 and the clamping shaft 124. To ensure the clamping effect on the cable 3, the distance between the clamping plate 121 and the clamping shaft 124 is less than the diameter of the clamped cable 3, or the former is greater than the latter's diameter. In this case, multiple strands of cable 3 need to be overlapped and clamped within the clamping area. Of course, binding and clamping methods can be used simultaneously to further ensure the fixation effect on the cable 3.

[0051] In one implementation, such as Figure 6 As shown, the width of the clamping plate 121 in the direction parallel to the length of the clamping shaft 124 is less than or equal to the distance between the two support plates 123. In this case, the clamping plate 121 can enter between the two support plates 123 to a certain depth. That is, when clamping the cable 3, the clamping plate 121 can be inserted into the two support plates 123, achieving a larger clamping range for the cable 3. The pin 122 is located in the area between the clamping surface and the non-clamping surface of the clamping plate 121. When the pin 122 is inserted into the socket 1231, the clamping surface is completely located between the two support plates 123, while the non-clamping surface is located outside the two support plates 123. If the distance between the pin 122 and the non-clamping surface is equal to the depth of the socket 1231, the non-clamping surface can also be flush with the top surface of the support plate 123. Therefore, after clamping the cable 3, the top surface of the entire driven assembly 1 remains flush (e.g., ...). Figure 3 (As shown), to reduce or avoid jamming between the driven component 1 and the obstruction when the component moves.

[0052] In one embodiment, the first body 11 is a permanent magnet, and the second body 21 is a ferromagnetic object, which can attract each other; alternatively, the first body 11 is a ferromagnetic object, and the second body 21 is a permanent magnet, which can attract each other; or, both the first body 11 and the second body 21 are permanent magnets, with opposite magnetic poles on the sides of the two permanent magnets that are close to each other. The permanent magnet can be a strong magnet to provide a strong magnetic force and ensure the strength of the magnetic attraction.

[0053] When using this utility model cable dragging tool, the cable 3 is fixedly connected to the driven component 1, and the driven component 1 and the driving component 2 are driven into the starting end of the obstruction (pipe 5 or partition 4). At this time, the driven component 1 and the driving component 2 are located on both sides of the obstruction, and they attract each other by magnetism. By moving the driving component 2, the driven component 1 and the cable 3 can be driven to move. During the movement, the movement trajectory can be referenced by the wiring diagram, or the movement resistance can be sensed at all times. If the resistance is abnormal, it means that the trajectory has deviated or the driven component 1 has separated from the driving component 2, which needs to be corrected in time. Finally, after the construction is completed, the cable is driven out from the end of the obstruction.

[0054] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
