Description

Technical Field

[0001] The invention relates to the technical field of cable construction protection, in particular to a temporary building power cable protection device. Background Art

[0002] During the construction process, steel bars need to be welded, and concrete needs to be vibrated when the foundation is poured. Therefore, temporary power cables and distribution boxes need to be laid. Temporary power cables play a vital role in construction. When laying temporary power cables, necessary protective measures should be taken. They can be laid overhead or underground, and obvious signs should be set up to avoid mechanical damage to the cables. At the same time, the cables should be prevented from being immersed in water, baked at high temperatures, and other adverse environmental influences.

[0003] According to a temporary power cable protection device for buildings disclosed in a Chinese patent document with announcement number CN218242881U, the cable is passed through a trapezoidal frame through the design of a positioning mechanism, the rotating plate drives the square rod to rotate, the auxiliary plate rotates and drives the threaded rod to rotate, and after the threaded rod rotates, the hollow rod drives the arc-shaped clamping plate to move downward until the cable is tightly fixed on the two pads, completing the cable fixing process. The trapezoidal frame can provide better protection for the cable, and the inner cavity space of the trapezoidal frame is larger, which is conducive to the heat dissipation of the cable, and when the trapezoidal frame undergoes a certain degree of deformation, it will not cause damage to the cable.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it was found that the cables are easily touched by construction workers or some transferred construction materials after being laid. At this time, the cables will generate a dragging force on the distribution box. When the above equipment is used, it is unable to buffer the dragging force of the cables. The cables directly dragging the distribution box may cause the connectors to loosen, resulting in poor contact, and may also damage the cables and cause leakage, thereby causing greater safety accidents.

[0005] Therefore, there is an urgent need to improve the temporary power cable protection device for buildings to solve the above-mentioned problems. Summary of the invention

[0006] The purpose of the present invention is to provide a temporary power cable protection device for buildings. The bottom frame can protect the distribution box body. The cable is wound on the winding column on the cable drum to form an S shape, which can improve the dragging resistance of the cable. When the cable is accidentally touched, the pulley roller can drive the slider to slide in the slide groove, so that the distance between the pulley roller and the winding column becomes shorter. The cable is temporarily stretched to buffer the dragging force, which not only reduces the risk of loosening of the distribution box connector, but also the pulley roller can reduce the wear of the cable and prevent the cable from being damaged, thereby greatly improving the safety of the use of temporary power cables.

[0007] In order to achieve the above object, the main technical solutions adopted by the present invention include: A temporary power cable protection device for buildings, comprising a base frame and a distribution box fixedly installed inside the base frame by bolts, a cable drum fixedly installed on both sides of the distribution box, two evenly distributed winding columns fixedly arranged on the cable drum, a slide groove is opened on the cable drum, a slider is slidably arranged inside the slide groove, a pulley roller is rotatably arranged on the slider, cables are fixedly connected to both ends of the distribution box, the cables are wound on the winding columns, and the cables are in contact with the pulley roller and extend to the outside of the base frame.

[0008] Preferably, a buffer mechanism is fixedly provided inside the slide groove, and the buffer mechanism includes an airbag and a return spring fixedly installed inside the airbag, one end of the airbag is fixedly connected to one side of the slider, and the cable is wound on the winding column on the drum to form an S shape, which can improve the dragging resistance of the cable. When the cable is accidentally touched, the pulley roller can drive the slider to slide in the slide groove, shortening the distance between the pulley roller and the winding column, and temporarily stretching the cable to buffer the dragging force, which not only reduces the risk of loosening of the distribution box connector, but also the pulley roller can reduce the friction of the cable to prevent damage to the cable.

The sliding of the slider causes the airbag to deform to buffer the drag force. At the same time, the gas in the airbag enters the air flow whistle through the air pipe. The sharp whistle emitted by the air flow whistle can help construction personnel respond in time and remind them to stay away, thereby fundamentally eliminating the occurrence of safety hazards. On the one hand, the reset spring can assist the airbag in buffering the drag force, and on the other hand, it can reset the airbag and refill it with gas for recycling.

[0012] Preferably, a fastening bolt is rotatably provided on the upper end of the fixing clamp, and the cable is fixedly arranged inside the fixing clamp by the fastening bolt. After the cable is contacted and dragged by an external object, the cable slides in the slide groove through the pulley roller transmission slider, and the cable is fixed by the fixing clamp. The clamp mounting block can slide in the sleeve shell through the buffer spring, thereby exerting a certain pulling force on the cable, and by cooperating with the force of the reset spring on the slider, on the one hand, the dragging bearing capacity of the cable can be greatly improved, and on the other hand, the cable can be quickly reset after the foreign object is away.

[0013] Preferably, the bottom frame is fixedly installed with a shell at a position corresponding to the buffer spring, and the clamp mounting block is slidably arranged inside the shell through the buffer spring. The holes are distributed in a straight line on the side of the wire reel close to the distribution box. A straight line is determined by two points to facilitate the installation of the wire reel.

The holes and grooves are distributed in a straight line on one side of the wire drum close to the distribution box, and a straight line is determined by two points to facilitate the installation of the wire drum, and the bottom end of the winding column abuts against the wire drum to facilitate disassembly.

[0016] Preferably, an arc-shaped protective cover is installed on the upper end of the bottom frame by means of a snap-fit, and the bottom side of the arc-shaped protective cover abuts against the upper ends of the I-shaped sealing strip and the sealing plate. The cooperation between the I-shaped sealing strip, the sealing plate and the arc-shaped protective cover can improve the sealing performance of the protective device, and can be waterproof and dustproof. The arc-shaped upper surface of the arc-shaped protective cover can reduce impact damage.

[0017] The present invention has at least the following beneficial effects: The bottom frame of the present invention can protect the distribution box body. The cable is wound on the winding column on the reel to form an S shape, which can improve the dragging resistance of the cable. When the cable is accidentally touched, the pulley roller can drive the slider to slide in the slide groove, so that the distance between the pulley roller and the winding column becomes shorter.

DETAILED DESCRIPTION

[0025] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] like Figure 1-Figure 8 As shown, the temporary power cable protection device for buildings provided in this embodiment includes a bottom frame 1 and a distribution box 2 fixedly installed inside the bottom frame 1 by bolts, the bottom frame 1 can protect the body of the distribution box 2, and a cable drum 3 is fixedly installed on both sides of the distribution box 2, and two evenly distributed winding columns 4 are fixedly arranged on the cable drum 3, and the cable 8 is S-shaped and wound around the winding columns 4 on the cable drum 3, and a slide groove 5 is opened on the cable drum 3, and a slider 6 is slidingly arranged inside the slide groove 5, and a pulley roller 7 is rotatably arranged on the slider 6, and cables 8 are rotatably connected to both ends of the distribution box 2, and the cable 8 is wound around the winding columns 4, and the cable 8 contacts the pulley roller 7 and extends to the outside of the bottom frame 1, and the distance between the pulley roller 7 and the winding column 4 is shortened during the sliding of the slider 6, and the cable 8 is temporarily stretched outside the bottom frame 1; Among them, the cable 8 is wound on the winding column 4 on the reel 3 to form an S shape, which can improve the dragging resistance of the cable 8. When the cable 8 is accidentally touched, the pulley roller 7 can drive the slider 6 to slide in the slide groove 5, so that the distance between the pulley roller 7 and the winding column 4 becomes shorter. The cable 8 is temporarily stretched to buffer the dragging force, which not only reduces the risk of the connector of the distribution box 2 being loose, but also the pulley roller 7 can reduce the friction of the cable 8 to prevent the cable from being damaged, thereby greatly improving the safety of the use of temporary power cables.

[0027] Further, such as Figure 1-Figure 8 As shown, a buffer mechanism 9 is fixedly arranged inside the slide groove 5, and the buffer mechanism 9 includes an airbag 901 and a return spring 902 fixedly installed inside the airbag 901, one end of the airbag 901 is fixedly connected to one side of the slider 6, and the end of the airbag 901 away from the slider 6 is fixedly connected to an air pipe 903, and the air pipe 903 extends to the outside of the wire drum 3, and the end of the air pipe 903 away from the wire drum 3 is fixedly connected to an air flow whistle 10; Among them, after the cable 8 is contacted and dragged by an external object, the cable 8 slides in the slide groove 5 through the pulley roller 7 to drive the slider 6. The sliding of the slider 6 causes the airbag 901 to deform to buffer the drag force. At the same time, the gas in the airbag 901 enters the airflow whistle 10 through the air pipe 903. The sharp whistle issued by the airflow whistle 10 can help the construction personnel to respond in time and remind the construction personnel to stay away, thus fundamentally eliminating the occurrence of safety hazards. The reset spring 902 can assist the airbag 901 in buffering the drag force on the one hand, and can reset the airbag 901 and refill it with gas on the other hand, so that it can be recycled, thereby greatly reducing the use cost of the temporary power cable protection device; Specifically, the airflow whistle 10 is usually made of a hollow tube, one end of which is closed and the other end has a small hole or opening. This structure allows the air to form a vortex and pressure change inside the whistle, thereby generating sound. Different airflow whistles can be selected for application in different architectural scenes. This is existing technology and will not be elaborated here.

[0028] Furthermore, Figure 1-Figure 8As shown, the bottom frame 1 is provided with a U-shaped wire groove 11 at a position corresponding to the cable 8, and an I-shaped sealing strip 12 is fixedly installed on the U-shaped wire groove 11. The cable 8 is slidably arranged inside the I-shaped sealing strip 12, and a sealing plate 13 is vertically slidably arranged inside the I-shaped sealing strip 12, and the bottom end of the sealing plate 13 is abutted against the cable 8. An arc-shaped protective cover 21 is installed on the upper end of the bottom frame 1 through a snap-fit, and the bottom side of the arc-shaped protective cover 21 is abutted against the upper ends of the I-shaped sealing strip 12 and the sealing plate 13. The U-shaped wire groove 11 is used to place the cable 8. The I-shaped sealing strip 12, the sealing plate 13 and the arc-shaped protective cover 21 cooperate to improve the sealing of the protective device, which can be waterproof and dustproof. The arc-shaped upper surface of the arc-shaped protective cover 21 can reduce impact damage, and the gas in the airbag 901 is discharged through the air pipe 903, which will increase air flow and have a certain heat dissipation effect, thereby extending the service life of the distribution box 2.

[0029] Furthermore, if Figure 1-Figure 8 As shown, two symmetrically distributed buffer springs 14 are fixedly installed on the inner side of the bottom frame 1, and the buffer springs 14 are fixedly installed on both sides below the U-shaped wire trough 11. The end of the U-shaped wire trough 11 away from the bottom frame 1 is fixedly connected with a fixture mounting block 15, and a fixing clamp 16 is fixedly provided on the upper end of the fixture mounting block 15. A fastening bolt 17 is rotatably provided on the upper end of the fixing clamp 16. The cable 8 is fixedly set inside the fixing clamp 16 through the fastening bolt 17. A sleeve 18 is fixedly installed on the bottom frame 1 at a position corresponding to the buffer spring 14, and the fixture mounting block 15 is slidably set inside the sleeve 18 through the buffer spring 14. Among them, after the cable 8 is contacted and dragged by an external object, the cable 8 slides in the slide groove 5 through the pulley roller 7 transmission slider 6, and the cable 8 is fixed by the fixing clamp 16. The clamp mounting block 15 can slide in the sleeve 18 through the buffer spring 14, thereby exerting a certain pulling force on the cable 8. By cooperating with the force of the reset spring 902 on the slider 6, on the one hand, the dragging bearing capacity of the cable 8 can be greatly improved, and on the other hand, the cable 8 can be quickly reset after the foreign object is away.

[0030] In addition, if Figure 1-Figure 8As shown, two symmetrically distributed supporting ribs 19 are fixedly provided on the bottom side of the casing 18, and the end of the supporting rib 19 away from the bottom frame 1 is fixedly installed on the inner wall of the bottom frame 1 by bolts, and the wire drum 3 is provided with two symmetrically distributed holes 20, and the holes 20 are linearly distributed on the side of the wire drum 3 close to the distribution box 2, and the pin shaft in the middle of the winding column 4 passes through the hole 20 and is fixedly connected to the inner bottom side surface of the bottom frame 1, and the holes 20 are linearly distributed on the side of the wire drum 3 close to the distribution box 2. A straight line is determined by two points, which is convenient for the installation of the wire drum 3, and the bottom end of the winding column 4 is against the wire drum 3, which is convenient for disassembly, and the supporting rib 19 can greatly improve the firmness of the casing 18.

[0031] like Figure 1-Figure 8 As shown, the principle of the temporary power cable protection device for buildings in this embodiment is as follows: During installation, open the arc-shaped protective cover 21, fix the distribution box 2 on the inner bottom side of the bottom frame 1, distribute the cable drum 3 symmetrically on both sides of the distribution box 2, wind the cable 8 on the winding column 4 on the cable drum 3 to form an S shape, and the cable 8 passes around the pulley roller 7. The cable 8 is fixed inside the fixing clamp 16 by the fastening bolts 17. The cable 8 finally passes through the inside of the U-shaped cable trough 11, and the sealing plate 13 is installed to seal the U-shaped cable trough 11. When the cable 8 is touched by mistake, the pulley roller 7 can drive the slider 6 to slide in the slide groove 5, so that the distance between the pulley roller 7 and the winding column 4 becomes shorter, and the sliding of the slider 6 causes the airbag 901 to deform to buffer the drag force. At the same time, the gas in the airbag 901 enters the airflow whistle 10 through the air pipe 903. The sharp whistle emitted by the airflow whistle 10 can help the construction workers to react in time and remind the construction workers to stay away. The temporary extension of the cable 8 buffers the drag force, which not only reduces the risk of the connector of the distribution box 2 being loose, but also reduces the risk of the pulley roller 7 The friction of cable 8 prevents cable damage. The reset spring 902 can assist the airbag 901 in buffering the drag force on the one hand, and can reset the airbag 901 and refill it with gas on the other hand, so that it can be recycled. The cable 8 is fixed by the fixing clamp 16, and the clamp mounting block 15 can slide in the sleeve 18 through the buffer spring 14, thereby exerting a certain pulling force on the cable 8. By cooperating with the force of the reset spring 902 on the slider 6, on the one hand, the dragging bearing capacity of the cable 8 can be greatly improved, and on the other hand, the cable 8 can be quickly reset after foreign objects are away.
