Description

Technical Field

[0001] The present invention relates to the technical field of building electrical construction, and particularly relates to a cable installation device for building electrical construction. Background Art

[0002] A cable is made of one or more mutually insulated conductors and an outer insulating protective layer, and is a wire for transmitting electricity or information from one place to another. During the construction of building electrical engineering, it is necessary to use a traction installation device to traction and guide the cable to be installed, so as to lay it. As long as the cable to be traction is passed through between two tracks, the two tracks drive the cable to move horizontally all the time, which can play a role in traction for the cable.

[0003] When the traction device lays and installs the cable, due to the complex construction site environment, external dust particles are easily attached to the surface of the cable. The dust may contain some sharp particles, such as sand grains, etc. During the process of the track traction of the cable, these sharp particles will generate friction with the relative movement of the cable and the track, which may scratch the outer skin of the cable. Once the outer skin of the cable is damaged, its insulation performance and protection ability will be reduced, and it is easy to cause the conductor inside the cable to be affected by the external environment, such as moisture, oxidation, etc., thereby affecting the normal use and service life of the cable.

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] Referring to Figures 1 - 14 , a cable installation device for building electrical construction, including a bottom plate 1, a driving mechanism 2 is fixedly installed on the upper surface of the bottom plate 1, a mounting plate 3 is fixedly installed on the upper surface of the bottom plate 1, two pairs of symmetrically distributed rotating openings are formed on the surface of the mounting plate 3, idler rollers 4 are rotatably installed in the rotating openings, a crawler belt 5 is wound around every two idler rollers 4, and multiple idler rollers 4 are controlled to rotate by a driving assembly. The driving assembly includes a driving motor 14 fixedly installed on the surface of the driving mechanism 2, the output shaft of the driving motor 14 is fixedly connected to one of the reciprocating lead screws 12, first gears 15 are fixedly sleeved on two of the idler rollers 4, the two first gears 15 are meshed and connected, and a liquid storage tank 6 is fixedly installed on the upper surface of the bottom plate 1.

[0020] The surface of the mounting plate 3 is symmetrically provided with mounting openings, and mounting rods 7 are fixedly installed in the mounting openings. One end of the mounting rod 7 is provided with a circular groove, and a piston rod 8 is slidably and sealingly inserted into the circular groove. The side wall of the mounting rod 7 is fixedly connected to the liquid storage tank 6 through a liquid inlet pipe 9. The surface of the mounting rod 7 is provided with a water outlet 10, and a liquid outlet pipe 11 is fixedly installed on the surface of the mounting rod 7. One end of the liquid outlet pipe 11 covers the water outlet 10, and the other end of the liquid outlet pipe 11 is fixedly installed with a spray head 45. First one-way valves are provided in both the liquid inlet pipe 9 and the liquid outlet pipe 11. The conduction direction of the first one-way valve in the liquid inlet pipe 9 is from the inside of the liquid storage tank 6 to the inside of the circular groove, and the conduction direction of the first one-way valve in the liquid outlet pipe 11 is from the inside of the circular groove to the spray head 45. The ends of two of the idler rollers 4 are fixedly installed with reciprocating lead screws 12, and sliding plates 13 are threadedly sleeved on the reciprocating lead screws 12. The two piston rods 8 are respectively fixedly connected to the two sliding plates 13.

[0021] Place the cable to be laid and installed between the two crawlers 5. The two spray heads 45 will be respectively located above and below the cable. Then start the drive motor 14 at this time. Under the driving action of the two first gears 15, multiple idler rollers 4 will all rotate together, and the two crawlers 5 will operate together, thereby tractionally conveying the cable located between them. During this process, the sliding plate 13 threadedly sleeved on the reciprocating lead screw 12 will drive the piston rod 8 to perform a horizontal reciprocating movement in the circular groove. The space volume between the end of the piston rod 8 and the groove wall of the circular groove will continuously change from small to large and then from large to small. When the space volume becomes larger, the pressure decreases, and the cleaning liquid in the liquid storage tank 6 will enter the circular groove from the liquid inlet pipe 9. When the space volume becomes smaller, the pressure increases, and the cleaning liquid in the circular groove will enter the spray head 45 from the liquid outlet pipe 11 and be sprayed in a mist, which can act on the surface of the cable, thereby achieving the effect of automatically cleaning the surface of the cable and preventing the dust attached to the surface of the cable from generating friction with the relative movement of the cable and the crawler 5, resulting in scratching the outer skin of the cable.

[0022] A scraping ring 16 is fixedly installed on the surface of the mounting plate 3 through a connecting rod. The upper surface of the bottom plate 1 is vertically fixedly installed with a first spring rod 17, and the top end of the first spring rod 17 is fixedly installed with a U-shaped supporting block 18. An annular sponge 19 is provided in the supporting block 18.

[0023] Place the cable to be laid and installed between the two crawlers 5, and make its forward end pass through the scraping ring 16 and the sponge 19. The scraping ring 16 can pre-scrape the cleaning liquid on the surface of the cable, while the sponge 19 can absorb the water stains of the remaining cleaning liquid on the surface of the cable, avoiding excessive water stains and not being cleaned. The cleaning liquid may contain chemical components. If it adheres to the cable outer skin for a long time, it will chemically react with the outer skin material, accelerating the aging, hardening or embrittlement of the outer skin, reducing the insulation performance and mechanical strength of the outer skin, shortening the service life of the cable. At the same time, it may also seep into the interior along the gaps or interfaces of the cable outer skin, resulting in a decrease in insulation performance, which will increase the risk of electrical faults such as short circuits and electric leakage in the cable, affecting the stability and safety of power transmission, and may cause safety accidents such as electrical fires in severe cases.

[0024] A rectangular plate 20 is fixedly installed on the surface of the mounting plate 3. A rotating rod 21 is rotatably installed on the surface of the rectangular plate 20. A second gear 22 is fixedly sleeved on the rotating rod 21. Two sliding grooves 23 are horizontally opened on the surface of the rectangular plate 20. A sliding rod 24 is slidably arranged in the sliding groove 23. One end of the sliding rod 24 located outside the sliding groove 23 is fixedly installed with a rack bar 25 meshed with the second gear 22. The rack bar 25 is fixedly installed with a U-shaped extrusion block 26 through a vertical rod. The sponge 19 is clamped between the two extrusion blocks 26. A second spring rod 27 is horizontally fixedly installed in one of the sliding grooves 23. One end of the second spring rod 27 is fixedly connected to the end of the sliding rod 24 located in the sliding groove 23. The two extrusion blocks 26 are controlled to approach each other through a pressing component. The pressing component includes a first T-shaped plate and an L-shaped pressing rod 28 fixedly installed at the end of the first T-shaped plate. The first T-shaped plate is fixedly installed between the two sliding plates 13. A placement plate 29 is fixedly installed on the surface of the extrusion block 26 close to the driving mechanism 2. The placement plate 29 is located on the moving path of the pressing rod 28.

[0025] When the sliding plate 13 drives the piston rod 8 to move into the mounting rod 7, the first T-shaped plate will also drive the pressing rod 28 to move. The end of the pressing rod 28 will abut against the surface of the placement plate 29, thereby pushing one of the extrusion blocks 26 towards the center of the sponge 19. At this time, the second spring rod 27 will contract. Under the transmission action of the second gear 22 and the two rack bars 25, the other extrusion block 26 will also move towards the center of the sponge 19, that is, the two extrusion blocks 26 will squeeze the sponge 19. When the sliding plate 13 drives the piston rod 8 to move out of the mounting rod 7, the thrust given by the pressing rod 28 to the placement plate 29 gradually disappears. Under the elastic potential energy of the second spring rod 27, the two extrusion blocks 26 will gradually move away from each other and reset.

[0026] The two extrusion blocks 26 can intermittently extrude the sponge 19, so as to squeeze out the cleaning liquid absorbed by the sponge 19, avoiding too much cleaning liquid absorbed by the sponge 19. And the cleaning liquid will accumulate at the bottom of the sponge 19 under the action of gravity. The downward gravity on the bottom of the sponge 19 is relatively large, causing a large displacement in the relative positions between its fiber structures, and then resulting in obvious dragging deformation at the bottom of the sponge 19, leading to the lower surface of the cable not being able to contact the deformed sponge 19 and unable to be effectively cleaned by the sponge 19.

[0027] A rectangular opening is formed on the surface of the placement plate 29, and a circular opening is formed on the upper surface of the placement plate 29. A rotating shaft 30 is vertically rotatably installed in the rectangular opening. The top end of the rotating shaft 30 passes through the circular opening and is fixedly installed with a fixing block. A torsion spring 31 is sleeved on the rotating shaft 30. The two ends of the torsion spring 31 are respectively fixedly connected with the fixing block and the placement plate 29. A baffle 32 is fixedly sleeved on the rotating shaft 30. The baffle 32 is located on the moving path of the abutting rod 28. A straight rod 33 is vertically fixedly installed on the upper surface of the placement plate 29. An L-shaped rotation limiting block 34 is slidably sleeved on the straight rod 33. The rotation limiting block 34 is connected to the first spring rod 17 through a connecting component. The connecting component includes a telescopic rod 35 and an L-shaped connecting plate 36 fixedly installed at one end of the telescopic rod 35. One end of the telescopic rod 35 is fixedly connected to the surface at the top end of the first spring rod 17. The surface of the connecting plate 36 is fixedly connected to one end of the rotation limiting block 34.

[0028] When the sponge 19 absorbs a large amount of water, causing deformation at its bottom and the lower surface of the cable being unable to contact the sponge 19, the gravity received by the supporting block 18 will also increase at this time. The first spring rod 17 will contract. At this time, the rotation limiting block 34 will also move downward together with the contraction of the first spring rod 17, and the surface of the rotation limiting block 34 will abut against the surface of the baffle 32 away from the driving mechanism 2. When the sponge 19 absorbs less water and the deformation amount at the bottom is smaller, and the lower surface of the cable can still contact the sponge 19, the contraction distance of the first spring rod 17 is relatively short at this time, and the surface of the rotation limiting block 34 will not abut against the surface of the baffle 32.

[0029] That is, when the sponge 19 absorbs less water and the abutting rod 28 moves in the direction close to the mounting plate 3, at this time, since the rotation limiting block 34 does not abut against the surface of the baffle 32, it will not have the effect of restricting the rotation direction of the baffle 32. When the abutting rod 28 abuts against the baffle 32 at this time, the end of the baffle 32 away from the rotating shaft 30 will be pushed by the abutting rod 28 and rotate in the direction away from the driving mechanism 2. At this time, the two extrusion blocks 26 will not move. When the abutting rod 28 moves to no longer abut against the baffle 32, the baffle 32 will quickly rotate back to its original position under the elastic potential energy of the torsion spring 31.

[0030] When the sponge 19 absorbs a large amount of water and the abutting rod 28 moves in the direction close to the mounting plate 3, since the rotation-limiting block 34 will move downward to abut against the surface of the baffle 32, the effect of restricting the rotation direction of the baffle 32 can be achieved. At this time, when the abutting rod 28 abuts against the baffle 32, since one end of the baffle 32 far from the rotating shaft 30 is restricted by the rotation-limiting block 34 and cannot rotate in the direction away from the driving mechanism 2, the baffle 32 will be pushed by the abutting rod 28 to drive the extrusion block 26 to move toward the center of the sponge 19. At this time, the telescopic rod 35 will contract, and the other extrusion block 26 will also move toward the center of the sponge 19, so as to extrude the sponge 19 and squeeze out the cleaning liquid absorbed inside it.

[0031] Only when the sponge 19 absorbs a large amount of water and deforms so that the lower surface of the cable cannot contact the sponge 19, the two extrusion blocks 26 will extrude the sponge 19 to squeeze out the cleaning liquid. When the sponge 19 absorbs less water, the two extrusion blocks 26 will not extrude the sponge 19, avoiding continuously and intermittently extruding the sponge 19, which will affect its service life and water absorption performance.

[0032] A central opening is formed at the center of one end of the mounting rod 7. A round rod 37 is rotatably installed in the central opening in a sealed manner. A water return port 38 is formed on the surface of the mounting rod 7, and a water return pipe 39 is fixedly installed on the surface of the mounting rod 7. One end of the water return pipe 39 covers the water return port 38, and the other end is fixedly connected to the liquid storage tank 6. An arc-shaped sealing plate 40 is fixedly installed on the surface of the round rod 37 through a connecting rod. The surface of the sealing plate 40 is in sliding sealing contact with the wall of the circular groove. The two round rods 37 are controlled to rotate relative to each other through a threaded component. The threaded component includes two threaded rods 41 with opposite thread directions. One end of the round rod 37 is provided with a threaded groove, and one end of each of the two threaded rods 41 is threadedly installed in the two threaded grooves respectively. The other ends of the two threaded rods 41 are fixedly installed with a second T-shaped plate. A third spring rod 42 is fixedly installed on the surface of the scraping ring 16. One end of the third spring rod 42 is fixedly connected to the surface of the second T-shaped plate. A contact rod 43 for contacting the cable is fixedly installed on the surface of the second T-shaped plate. A spherical groove is formed at the end of the contact rod 43 far from the second T-shaped plate, and a rolling ball 44 is rollingly embedded in the spherical groove. A second one-way valve is arranged in the water return pipe 39, and the conduction direction of the second one-way valve in the water return pipe 39 is from the inside of the circular groove to the inside of the liquid storage tank 6.

[0033] When there is no cable in the scraping ring 16, the third spring rod 42 will not be stretched at this time. At this time, the two plugging plates 40 will respectively cover and block the two water outlets 10, making the two water outlets 10 in a closed state, while the two water return ports 38 will be in an open state. At this time, when the piston rod 8 reciprocates in the mounting rod 7, the cleaning liquid in the liquid storage tank 6 will enter the circular groove from the liquid inlet pipe 9, and then flow back to the liquid storage tank 6 through the water return pipe 39. When there is a cable passing through the scraping ring 16, at this time, the ball 44 at the end of the contact rod 43 will abut against the surface of the cable, and the third spring rod 42 will be stretched and drive the two threaded rods 41 to move together. Since the threaded rods 41 cannot rotate, under the cooperation of the threads, the two round rods 37 will rotate relatively, and the two plugging plates 40 will respectively rotate to cover and block the two water return ports 38, making the two water return ports 38 closed, while the two water outlets 10 are in an open state. At this time, when the piston rod 8 reciprocates in the mounting rod 7, the cleaning liquid in the liquid storage tank 6 will enter the circular groove from the liquid inlet pipe 9, and then enter the spray head 45 through the liquid outlet pipe 11.

[0034] When the cable traction work is over, the ball 44 is no longer in contact with the cable, and the contact rod 43 and the ball 44 will quickly move back to their original positions under the elastic potential energy of the third spring rod 42, and the two threaded rods 41 will also quickly move back to their original positions. The two round rods 37 will respectively drive the two plugging plates 40 to rotate, and the two plugging plates 40 will respectively cover and block the two water outlets 10, making the two water outlets 10 in a closed state, while the two water return ports 38 will be in an open state. At this time, when the piston rod 8 reciprocates in the mounting rod 7, the cleaning liquid in the liquid storage tank 6 will enter the circular groove from the liquid inlet pipe 9, and then flow back to the liquid storage tank 6 through the water return pipe 39, avoiding that after the cable traction work is over, due to the failure to turn off the driving motor 14 in time, the spray head 45 keeps spraying the cleaning liquid, wasting resources.

[0035] In the present invention, the cable to be laid and installed is placed between the two crawlers 5, and the two spray heads 45 are respectively located above and below the cable. Then, at this time, the driving assembly is used to control the rotation of multiple idler rollers 4 together, and the two crawlers 5 will operate together, thereby traction-conveying the cable located between them. During this process, the sliding plate 13 threadedly sleeved on the reciprocating screw rod 12 will drive the piston rod 8 to perform a horizontal reciprocating movement in the circular groove, and intermittently spray the cleaning liquid in the liquid storage tank 6 in a mist form from the two spray heads 45 and act on the surface of the cable, thereby achieving the effect of automatically cleaning the surface of the cable, avoiding that the attached dust will cause friction with the relative movement of the cable and the crawler 5, resulting in scratching the outer skin of the cable, and there is no need for an additional electric driving device, and no additional electric cost will be generated.

[0036] As described above, it is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
