Description

Technical Field

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

[0002] Cables are made of one or more mutually insulated conductors and an outer insulating protective layer. They are wires that transmit electricity or information from one place to another. During the construction of building electrical equipment, the cables to be installed need to be pulled and guided by traction installation equipment for laying. As long as the cable to be pulled passes between two crawlers, the two crawlers will drive the cable to move horizontally to pull the cable.

[0003] When the traction device is laying and installing cables, due to the complex construction site environment, external dust particles are easy to adhere to the cable surface. The dust may contain some sharp particles, such as sand. In the process of the crawler pulling the cable, these sharp particles will produce friction with the relative movement of the cable and the crawler, which may scratch the cable sheath. Once the cable sheath is damaged, its insulation performance and protection ability will be reduced, and the conductor inside the cable will easily be affected by the external environment, such as moisture, oxidation, etc., thereby affecting the normal use and life of the cable.

When the traction of the cable is completed, the contact rod is no longer in contact with the cable, and the nozzle can be controlled to stop spraying cleaning fluid, avoiding waste of resources.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] Reference Figures 1-14 A cable installation device for building electrical construction includes a base plate 1, a driving mechanism 2 is fixedly installed on the upper surface of the base plate 1, a mounting plate 3 is fixedly installed on the upper surface of the base plate 1, and two pairs of symmetrically distributed rotating openings are opened on the surface of the mounting plate 3. Rollers 4 are rotatably installed in the rotating openings, and a crawler 5 is wound around every two rollers 4. The rotation of multiple rollers 4 is controlled by a driving assembly, and the driving assembly includes a driving motor 14 fixedly installed on the surface of the driving mechanism 2, and the output shaft of the driving motor 14 is fixedly connected to one of the reciprocating screws 12, wherein the two rollers 4 are fixedly sleeved with a first gear 15, and the two first gears 15 are meshed and connected, and a liquid storage tank 6 is fixedly installed on the upper surface of the base plate 1.

[0037] The surface of the mounting plate 3 is symmetrically provided with mounting ports, in which a mounting rod 7 is fixedly installed, one end of the mounting rod 7 is provided with a circular groove, and a piston rod 8 is inserted in the circular groove for sliding sealing. The side wall of the mounting rod 7 is fixedly connected to the liquid storage tank 6 through a liquid inlet pipe 9. A water outlet 10 is provided on the surface of the mounting rod 7, 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 a nozzle 45 is fixedly installed on the other end of the liquid outlet pipe 11. A first one-way valve is provided in both the liquid inlet pipe 9 and the liquid outlet pipe 11. The conducting direction of the first one-way valve in the liquid inlet pipe 9 is from the liquid storage tank 6 to the circular groove, and the conducting direction of the first one-way valve in the liquid outlet pipe 11 is from the circular groove to the nozzle 45. The ends of the two rollers 4 are fixedly installed with a reciprocating screw 12, and a slide plate 13 is threadedly sleeved on the reciprocating screw 12. The two piston rods 8 are fixedly connected to the two slide plates 13 respectively.

[0038] The cable to be laid and installed is placed between the two crawlers 5, and the two nozzles 45 are respectively located above and below the cable. Then, the drive motor 14 is started. Under the transmission action of the two first gears 15, the multiple rollers 4 will rotate together, and the two crawlers 5 will run together, thereby pulling and conveying the cable between them. In this process, the slide 13 threadedly sleeved on the reciprocating screw 12 will carry the piston rod 8 to move back and forth horizontally in the circular groove, and the space volume between the end of the piston rod 8 and the wall of the circular groove is 1 / 4. It will continue to 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 nozzle 45 from the liquid outlet pipe 11 and be sprayed out in the form of mist, which can act on the surface of the cable, thereby achieving the effect of automatically cleaning the cable surface and avoiding the dust attached to the cable surface from generating friction with the relative movement of the cable and the crawler 5, causing scratches on the cable sheath.

[0039] A scraper ring 16 is fixedly mounted on the surface of the mounting plate 3 via a connecting rod. A first spring rod 17 is vertically fixedly mounted on the upper surface of the base plate 1 . A U-shaped supporting block 18 is fixedly mounted on the top end of the first spring rod 17 . An annular sponge 19 is provided inside the supporting block 18 .

[0040] Place the cable to be laid and installed between the two tracks 5, and pass its forward end through the scraper ring 16 and the sponge 19. The scraper ring 16 can pre-scrape the cleaning liquid on the cable surface, and the sponge 19 can absorb the water stains of the cleaning liquid remaining on the cable surface to avoid a lot of water stains. If the water stains are not cleaned, the cleaning liquid may contain chemical components. If it adheres to the cable sheath for a long time, it will react chemically with the sheath material, accelerate the aging of the sheath, harden or become brittle, reduce the insulation performance and mechanical strength of the sheath, and shorten the service life of the cable. At the same time, it may also penetrate into the interior through the gaps or interfaces of the cable sheath, resulting in a decrease in insulation performance, which will increase the risk of electrical faults such as short circuit and leakage in the cable, affect the stability and safety of power transmission, and in severe cases may cause safety accidents such as electrical fires.

[0041] A rectangular plate 20 is fixedly mounted on the surface of the mounting plate 3, and a rotating rod 21 is rotatably mounted on the surface of the rectangular plate 20. A second gear 22 is fixedly sleeved on the rotating rod 21. Two slide grooves 23 are horizontally provided on the surface of the rectangular plate 20. A slide rod 24 is slidably configured in the slide groove 23. One end of the slide rod 24 located outside the slide groove 23 is fixedly mounted with a rack rod 25 engaged with the second gear 22. The rack rod 25 is fixedly mounted with a U-shaped extrusion block 26 through a vertical rod. The sponge 19 is clamped between the two extrusion blocks 26, one of which is A second spring rod 27 is fixedly installed horizontally in each slide groove 23, and one end of the second spring rod 27 is fixedly connected to the end of the slide rod 24 located in the slide groove 23. The two extrusion blocks 26 are controlled to approach each other through a pressing assembly. The pressing assembly 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 slides 13. A placement plate 29 is fixedly installed on the surface of the extrusion block 26 close to the driving mechanism 2, and the placement plate 29 is located on the moving path of the pressing rod 28.

[0042] When the slide plate 13 moves toward the inside of the mounting rod 7 with the piston rod 8, the first T-shaped plate will also move with the push rod 28, and the end of the push rod 28 will abut against the surface of the placement plate 29, thereby pushing one of the extrusion blocks 26 to move toward the center of the sponge 19. At this time, the second spring rod 27 will contract, and under the transmission action of the second gear 22 and the two rack rods 25, the other extrusion block 26 will also move toward the center of the sponge 19, that is, the two extrusion blocks 26 will squeeze the sponge 19, and when the slide plate 13 moves toward the outside of the mounting rod 7 with the piston rod 8, the thrust given to the placement plate 29 by the push rod 28 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.

[0043] The two squeezing blocks 26 can intermittently squeeze the sponge 19, thereby squeezing out the cleaning liquid absorbed by the sponge 19, preventing the sponge 19 from absorbing too much cleaning liquid, and the cleaning liquid will accumulate at the bottom of the sponge 19 under the action of gravity. The bottom of the sponge 19 is subjected to a large downward gravity, resulting in a large displacement of the relative position between its fiber structures, and then causing obvious drag deformation at the bottom of the sponge 19, resulting in the lower surface of the cable being unable to contact the deformed sponge 19, and unable to be effectively cleaned by the sponge 19.

[0044] The surface of the placement plate 29 is provided with a rectangular opening, and the upper surface of the placement plate 29 is provided with a circular opening. A rotating shaft 30 is vertically rotatably installed in the rectangular opening. The top of the rotating shaft 30 passes through the circular opening and is fixedly installed with a fixed block. A torsion spring 31 is sleeved on the rotating shaft 30, and the two ends of the torsion spring 31 are respectively fixedly connected to the fixed block and the placement plate 29. A baffle 32 is fixedly sleeved on the rotating shaft 30, and the baffle 32 is located on the moving path of the push rod 28. A straight rod 33 is vertically fixedly installed on the upper surface of the placement plate 29, and an L-shaped rotation limit block 34 is slidably sleeved on the straight rod 33. The rotation limit 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 of the first spring rod 17, and the surface of the connecting plate 36 is fixedly connected to one end of the rotation limit block 34.

[0045] When the sponge 19 absorbs more water, causing its bottom to deform and the lower surface of the cable to be unable to contact the sponge 19, the gravity acting on the supporting block 18 will also increase, and the first spring rod 17 will contract. At this time, the rotation limit block 34 will also move downward with the contraction of the first spring rod 17, and the surface of the rotation limit block 34 will be against the surface of the baffle 32 away from the driving mechanism 2. When the sponge 19 absorbs less water and the deformation of the bottom is small, the lower surface of the cable can still contact the sponge 19. At this time, the contraction distance of the first spring rod 17 is also shorter, and the surface of the rotation limit block 34 will not be against the surface of the baffle 32.

[0046] That is, when the sponge 19 absorbs less water and the push rod 28 moves in the direction closer to the mounting plate 3, the limiting block 34 will not abut against the surface of the baffle 32, and thus will not limit the rotation direction of the baffle 32. At this time, when the push rod 28 abuts against the baffle 32, the end of the baffle 32 away from the rotating shaft 30 will be pushed by the push 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 push rod 28 moves to the point where it no longer abuts against the baffle 32, the baffle 32 will quickly rotate and reset under the elastic potential energy of the torsion spring 31.

[0047] When the sponge 19 absorbs more water and the push rod 28 moves toward the mounting plate 3, the limiting block 34 will move down to abut against the surface of the baffle 32, thereby limiting the rotation direction of the baffle 32. At this time, when the push rod 28 abuts against the baffle 32, the end of the baffle 32 away from the rotating shaft 30 is restricted by the limiting block 34 and cannot rotate in the direction away from the driving mechanism 2. As a result, the baffle 32 will be pushed by the push rod 28 and move with the squeezing block 26 toward the center of the sponge 19. At this time, the telescopic rod 35 will contract, and the other squeezing block 26 will also move toward the center of the sponge 19, thereby squeezing the sponge 19 and squeezing the cleaning liquid absorbed inside it.

[0048] Only when the sponge 19 absorbs a lot of water and is deformed, and the lower surface of the cable cannot contact the sponge 19, the two squeezing blocks 26 will squeeze the sponge 19 to squeeze out the cleaning liquid. When the sponge 19 absorbs less water, the two squeezing blocks 26 will not squeeze the sponge 19 to avoid intermittent squeezing of the sponge 19, which will affect its service life and water absorption performance.

[0049] A central opening is provided at the center of one end of the mounting rod 7, and a round rod 37 is sealed and rotatably installed in the central opening. A return water port 38 is provided on the surface of the mounting rod 7, and a return water pipe 39 is fixedly installed on the surface of the mounting rod 7. One end of the return water pipe 39 covers the return water 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 and sealing contact with the wall of the circular groove. The two round rods 37 are controlled to rotate relative to each other by a threaded component. The threaded component includes two threaded rods 41 with opposite thread directions. A threaded groove is provided at one end of the round rod 37. One end of the two threaded rods 41 is threadedly installed in the two threaded grooves respectively, and the other end of the two threaded rods 41 is fixedly installed with a second T-shaped plate. A third spring rod 42 is fixedly installed on the surface of the scraper ring 16, and 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 provided at the end of the contact rod 43 away from the second T-shaped plate, and a rolling ball 44 is rolled and embedded in the spherical groove. A second one-way valve is provided in the return pipe 39, and the conduction direction of the second one-way valve in the return pipe 39 is from the circular groove to the liquid storage tank 6.

[0050] When there is no cable in the scraper ring 16, the third spring rod 42 will not stretch, and the two blocking plates 40 will cover and block the two water outlets 10 respectively, so that the two water outlets 10 are in a closed state, and the two return water ports 38 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 flow back to the liquid storage tank 6 from the return water pipe 39. When the cable passes through the scraper ring 16, the ball 44 at the end of the contact rod 43 will contact the The surfaces of the cables are against each other, the third spring rod 42 will stretch, and move with the two threaded rods 41. Since the threaded rod 41 cannot rotate, the two round rods 37 will rotate relative to each other with the cooperation of the threads, and the two blocking plates 40 will rotate to cover and block the two return water ports 38 respectively, so that the two return water ports 38 are closed, and the two water outlets 10 are in an open state. At this time, when the piston rod 8 moves back and forth 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 nozzle 45 from the liquid outlet pipe 11.

[0051] When the cable pulling work is completed, the ball 44 is no longer in contact with the cable, and the contact rod 43 and the ball 44 will quickly move and reset under the elastic potential energy of the third spring rod 42, and the two threaded rods 41 will also quickly move and reset, and the two round rods 37 will respectively rotate with the two blocking plates 40, and the two blocking plates 40 will respectively cover and block the two water outlets 10, so that the two water outlets 10 are in a closed state, and the two return water ports 38 are in an open state. At this time, when the piston rod 8 moves back and forth 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 from the return water pipe 39, so as to avoid the nozzle 45 from spraying cleaning liquid continuously after the cable pulling work is completed due to the failure to shut down the drive motor 14 in time, thereby wasting resources.

[0052] In the present invention, the cable to be laid and installed is placed between the two tracks 5, and the two nozzles 45 are respectively located above and below the cable. Then, the driving assembly controls the multiple rollers 4 to rotate together, and the two tracks 5 will run together, thereby pulling and transporting the cable between them. In this process, the slide 13 threaded on the reciprocating screw 12 will carry the piston rod 8 to move back and forth horizontally in the circular groove, and the cleaning liquid in the liquid storage tank 6 can be intermittently sprayed out in the form of mist from the two nozzles 45 and act on the surface of the cable, thereby achieving the effect of automatically cleaning the cable surface, avoiding the attached dust from generating friction with the relative movement of the cable and the track 5, causing scratches on the cable sheath, and no additional electric drive device is required, and no additional electricity cost is generated.

[0053] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
