Description

Technical Field

[0001] The present invention relates to the technical field of temporary line laying, in particular to a temporary line laying device at a construction site. Background Art

[0002] In the construction industry, the proper laying and support of cables is a key element in ensuring on-site safety. Due to the complex environment of construction sites, with a large amount of moving machinery, stacked materials, and frequent personnel movement, cables laid directly on the ground without effective support devices are highly susceptible to crushing, pulling, or damage from external forces, potentially causing electrical faults such as leakage and short circuits, and even potentially leading to serious safety accidents such as electric shock and fire.

[0003] Chinese patent CN205123133U discloses a detachable construction cable bracket, which was originally designed to provide hanging support for cables at the construction site to solve the problem of cables dragging on the ground. However, this bracket still has certain limitations in practical applications. Its working principle is based on ground placement to assume the cable suspension function, which requires the bracket to ensure the stability of the overall center of gravity during the placement process. However, in the dynamic and complex environment of the construction site, there are many uncontrollable factors, such as vibrations generated by construction machinery during operation, uneven ground at the construction site, and inadvertent collisions between people or vehicles, which may interfere with the stability of the bracket. Once the center of gravity of the bracket is unbalanced, it is very easy to tip over, causing the suspended cables to fall off. Not only can it fail to effectively solve the problem of cables dragging on the ground, it may also cause new safety hazards, affecting construction safety and efficiency.

[0004] How to solve the above problems is the research topic of this program. Summary of the Invention

[0005] In order to achieve the above-mentioned purpose of the invention and to address the above-mentioned technical problems, the present invention provides a temporary line installation device for a construction site.

[0006] The technical solution is as follows: it includes a U-shaped clamp fixedly connected to the installation pipe, a first C-shaped channel steel and a second C-shaped channel steel connecting the ceiling and the U-shaped clamp, wherein the first C-shaped channel steel is arranged obliquely and the second C-shaped channel steel is arranged vertically; The ceiling is provided with a first adjustable hinge and a second adjustable hinge, both of which are fixed to the ceiling by expansion bolts. This method of fixing with expansion bolts can ensure that the adjustable hinge is firmly installed on the ceiling, withstands the pressure brought by subsequent structures and loads, and is not easy to loosen or fall off, providing a solid foundation support for the entire temporary line pulling device; The first adjustable hinge is connected to one end of the first C-shaped channel steel, and the second adjustable hinge is connected to one end of the second C-shaped channel steel. The introduction of the C-shaped channel steel not only provides an installation interface for subsequent components, but also has high structural strength, which can ensure the stability of the entire device during operation, is not prone to deformation or damage, and effectively extends the service life of the device; The other end of the first C-shaped channel steel is connected to a third adjustable hinge, and the other end of the second C-shaped channel steel is connected to a fourth adjustable hinge. The third and fourth adjustable hinges are connected in a U-shaped clamp, and an installation pipe is placed in the U-shaped clamp.

[0007] The U-shaped clamp includes a clamping ring, which is clamped on the installation pipe. Two ear plates are provided at the opening of the clamping ring. The two ear plates and one end of the fourth adjustable hinge are locked and fixed by a first nut and a first bolt. This clamping and locking method can ensure that the clamp is firmly fixed on the installation pipe and will not loosen or shift due to external force, thereby ensuring the stability and safety of the entire device.

[0008] The base of the clamping ring is equipped with a suspension rod and a locking nut. An insulating hook is mounted on the suspension rod, and several cables are placed on the insulating hook. The combination of the suspension rod and locking nut provides stable support for the insulating hook, allowing it to reliably bear the weight of the cables, preventing them from sagging or shaking due to their own weight, and ensuring the normal operation of the line.

[0009] Vertical ear plates are provided on both sides of the outer wall of the clamping ring, a C-shaped connecting plate is provided between the two vertical ear plates, a second bolt is provided through the two side plates of the C-shaped connecting plate and the two vertical ear plates, and the two side plates of the C-shaped connecting plate, the two vertical ear plates and one end of the third adjustable hinge are locked and fixed by a second nut.

[0010] The insulating hook comprises a hook body and a collar mounted on one side of the hook body's top. The collar is mounted on the outer wall of the sling and slidably engages with the sling. An insulating rod is mounted on one side of the collar, and several insulating curved plates, evenly distributed vertically on the other side of the insulating rod, are used to position cables. The sliding engagement between the collar and the sling allows the insulating hook to be flexibly adjusted based on actual needs, facilitating cable placement and management. The insulating rod and insulating curved plates not only provide space for cable placement, but also provide insulation that effectively prevents safety hazards such as electrical leakage, ensuring the safety of construction workers.

[0011] In order to avoid damage to the cables caused by dragging, a plurality of mounting grooves are provided in the insulating arc plate, a rotating shaft is provided in the mounting groove, and a roller is provided on the rotating shaft, and the roller is arranged along the direction of the installation pipe; The two ends of the rotating shaft are rotatably connected to the inner wall of the installation groove. This design makes it easy to pull the cable between the roller and prevent the cable from falling from the insulating curved plate.

[0012] The introduction of rollers converts the sliding friction between the cable and the insulating curved plate into rolling friction, which greatly reduces the resistance when the cable is dragged, reduces cable wear, and extends the service life of the cable; at the same time, the rollers are set along the direction of the installation pipeline to ensure the smoothness of cable dragging and improve construction efficiency.

[0013] A rubber anti-skid layer is formed on the surface of the roller. The provision of the rubber anti-skid layer increases the friction between the roller and the cable, preventing the cable from slipping during the dragging process.

[0014] The insulating hook includes a hook body and a collar provided on one side of the top of the hook body, the collar is sleeved on the outer wall of the hanging rod and slidably cooperates with the hanging rod, an insulating rod is provided on one side of the collar, an arc-shaped hanging plate is provided at the bottom of the insulating rod, a plurality of lifting sleeves are slidably cooperated on the insulating rod, a plurality of insulating arc plates for placing cables are provided on one side of the lifting sleeve, the outer end of the insulating arc plate is bent upward, a blocking plate is provided at the bottom of the insulating arc plate obliquely downward, and a locking nut for fixing the lifting sleeve is threadedly connected to the insulating rod; At the very bottom, the curved hanging plate and the adjacent blocking plate on the side of the upper lifting sleeve cooperate to form a closed cavity; above the hanging plate, the insulating curved plate on the lower lifting sleeve and the blocking plate on the side of the upper lifting sleeve cooperate to form a closed cavity. The blocking plate can cooperate with the adjacent insulating curved plate to prevent the cables from falling out of the insulating curved plate, ensuring the stable placement of the cables. The design of the lifting sleeve allows the insulating curved plate to be flexibly adjusted according to the height requirements of the cables, improving the applicability of the device; the locking nut can fix the position of the lifting sleeve, ensuring that the insulating curved plate will not move arbitrarily after being adjusted to the appropriate height, thus ensuring the stability of the device.

[0015] The insulating hook includes a hook body and a collar provided on one side of the top of the hook body. The collar is sleeved on the outer wall of the suspension rod and slidably cooperates with the suspension rod. An insulating rod is provided on one side of the collar, and a plurality of insulating arc plates for placing cables are provided on the insulating rod. The insulating arc plate is provided with a plurality of through holes, and a flexible plate is provided on the outer wall of the insulating arc plate. The flexible plate is fixedly connected to the bottom of the insulating arc plate by a left bolt and a right bolt. The outer wall of the insulating arc plate is provided with a plurality of threaded holes, and the threaded holes match the threads of the left bolt and the right bolt. The flexible plate is provided with a plurality of ball grooves, in which rolling balls are arranged. After passing through the through holes, the rolling balls are higher than the upper surface of the insulating arc plate.

[0016] The setting of the rolling ball changes the contact mode between the cable and the insulating curved plate from sliding contact to rolling contact, further reducing the resistance when the cable is dragged, making the cable dragging easier and smoother, improving construction efficiency, and also reducing the risk of cable damage due to friction; The introduction of the flexible plate allows for the left end of the flexible plate to be pulled down to the edge of the insulating arc plate below by loosening the left bolt when the cable does not need to be pulled again, and then tightened again with the left bolt to form a closed loop, effectively preventing the cable from falling from the insulating arc plate and improving the safety and reliability of the device.

[0017] The technical solution provided by the embodiment of the present invention has the following beneficial effects: (1) Insulation performance and safety The insulating hook is made of insulating material, which effectively prevents safety hazards such as leakage and ensures the safety of construction workers.

[0018] By setting up the blocking plate and the flexible plate, the cables are effectively prevented from falling from the insulating arc plate, ensuring the stable placement of the cables, and also facilitating the unified management and maintenance of the cables.

[0019] (2) Cable drag and wear The setting of the roller and the ball converts the sliding friction between the cable and the insulating curved plate into rolling friction, which greatly reduces the resistance when the cable is dragged, reduces the wear of the cable, and extends the service life of the cable.

[0020] The rollers are arranged along the direction of the installation pipe, ensuring the smoothness of cable dragging and improving construction efficiency; the introduction of the flexible plate enables the flexible plate to be pulled down to the edge of the insulating arc plate below by loosening the bolts when the cable does not need to be pulled again, and then tightened and fixed again to form a closed loop, effectively preventing the cable from falling from the insulating arc plate, thereby improving the safety and reliability of the device.

[0021] (3) Structural stability and service life The introduction of C-shaped channel steel not only provides an installation interface for subsequent components, but also has high structural strength, which can ensure the stability of the entire device during operation, making it less likely to deform or damage, and effectively extending the service life of the device; the adjustable hinge is fixed to the ceiling with expansion bolts, which can ensure its stable installation, withstand the pressure brought by subsequent structures and loads, and is not easy to loosen or fall off, providing a solid foundation support for the entire temporary line pulling device.

[0022] The clamp is clamped on the installation pipe and fixed by nuts and bolts, which can ensure that the clamp is firmly fixed on the installation pipe and will not loosen or shift due to external forces, thereby ensuring the stability and safety of the entire device.

[0023] (4) Device flexibility and applicability The insulating hook slides with the hanging rod through the ring, so that the insulating hook can be flexibly adjusted according to actual needs, which is convenient for the arrangement and management of cables.

[0024] The invention provides various forms of insulating hooks, such as insulating hooks with rollers, balls and flexible plates. These designs not only reduce the resistance when dragging the cable and reduce cable wear, but also improve the stability and safety of cable placement and enhance the applicability of the device.

[0025] The design of the lifting sleeve allows the insulating curved plate to be flexibly adjusted according to the height requirements of the cable, improving the applicability of the device; the locking nut can fix the position of the lifting sleeve, ensuring that the insulating curved plate will not move at will after being adjusted to the appropriate height, thereby ensuring the stability of the device.

[0026] (5) Installation and maintenance The entire device adopts a modular design, and the components are easily connected and easy to install and disassemble. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Example 1 See also Figures 1 to 7 The present invention provides a temporary line device for pulling on a construction site, comprising a U-shaped clamp fixedly connected to an installation pipe, a first C-shaped channel steel 102 and a second C-shaped channel steel 104 connecting a ceiling 100 and the U-shaped clamp, wherein the first C-shaped channel steel 102 is arranged obliquely and the second C-shaped channel steel 104 is arranged vertically; The ceiling 100 is provided with a first adjustable hinge 101 and a second adjustable hinge 103. The first adjustable hinge 101 and the second adjustable hinge 103 are both fixed to the ceiling by expansion bolts. This method of fixing with expansion bolts can ensure that the adjustable hinges are firmly installed on the ceiling, withstand the pressure brought by subsequent structures and loads, and are not easy to loosen or fall off, providing a solid foundation support for the entire temporary line pulling device. The first adjustable hinge 101 is connected to one end of the first C-shaped channel steel 102, and the second adjustable hinge 103 is connected to one end of the second C-shaped channel steel 104. The introduction of the C-shaped channel steel not only provides an installation interface for subsequent components, but also has high structural strength, which can ensure the stability of the entire device during operation, is not prone to deformation or damage, and effectively extends the service life of the device; The other end of the first C-shaped channel steel 102 is connected to the third adjustable hinge 105, and the other end of the second C-shaped channel steel 104 is connected to the fourth adjustable hinge 106. The third adjustable hinge 105 and the fourth adjustable hinge 106 are connected in the U-shaped clamp 11, and the installation pipe 108 is placed in the U-shaped clamp 11.

[0040] The U-shaped clamp includes a clamping ring 11, which is clamped on the installation pipe. Two ear plates are provided at the opening of the clamping ring 11. The two ear plates and one end of the fourth adjustable hinge 106 are locked and fixed by a first nut 13 and a first bolt 12; this clamping and locking method can ensure that the clamp is firmly fixed on the installation pipe and will not loosen or shift due to external force, thereby ensuring the stability and safety of the entire device.

[0041] At the bottom of the clamping ring 11 is a suspension rod 2, which is fitted with a locking nut 21. An insulating hook is sleeved onto the suspension rod 2, on which several cables 200 are placed. The combination of the suspension rod and locking nut provides stable support for the insulating hook, enabling it to reliably bear the weight of the cables, preventing them from sagging or swaying due to their own weight, and ensuring the normal operation of the line.

[0042] Vertical ear plates are provided on both sides of the outer wall of the retaining ring 11, a C-shaped connecting plate 17 is provided between the two vertical ear plates, a second bolt is provided through the two side plates of the C-shaped connecting plate 17 and the two vertical ear plates, and the two side plates of the C-shaped connecting plate 17, the two vertical ear plates and one end of the third adjustable hinge 105 are locked and fixed by a second nut.

[0043] The insulating hook includes a hook body and a collar 4 positioned on one side of the hook body's top. The collar 4 is mounted on the outer wall of the sling 2 and slides with the sling 2. An insulating rod 3 is positioned on one side of the collar 4, and several insulating curved plates 31, evenly distributed vertically on the other side of the insulating rod 3, are used to hold cables 200. The sliding fit between the collar and the sling allows the insulating hook to be flexibly adjusted according to actual needs, facilitating cable placement and management. The insulating rod and curved plates not only provide space for cable placement, but also provide insulation that effectively prevents safety hazards such as electrical leakage, ensuring the safety of construction workers.

[0044] Example 2 On the basis of Example 1, in order to avoid cable damage caused by dragging the cable, Figure 2 and Figure 3 As shown, a plurality of mounting grooves 51 are provided in the insulating arc plate 31, a rotating shaft 52 is provided in the mounting groove 51, a roller 53 is provided on the rotating shaft, and the roller 53 is arranged along the direction of the mounting pipe 108; The two ends of the rotating shaft 52 are rotatably connected to the inner wall of the mounting groove 51. This design makes it easy to pull the cable between the roller and prevent the cable from falling from the insulating curved plate.

[0045] The introduction of rollers converts the sliding friction between the cable and the insulating curved plate into rolling friction, which greatly reduces the resistance when the cable is dragged, reduces cable wear, and extends the service life of the cable; at the same time, the rollers are set along the direction of the installation pipeline to ensure the smoothness of cable dragging and improve construction efficiency.

[0046] Example 3 On the basis of embodiment 2, a rubber anti-skid layer is further formed on the surface of the roller 53. The provision of the rubber anti-skid layer increases the friction between the roller and the cable, preventing the cable from slipping during the dragging process.

[0047] Example 4 On the basis of Example 1, the difference from Example 1 is that Figure 4As shown, the insulating hook includes a hook body and a ring 4 arranged on one side of the top of the hook body. The ring 4 is sleeved on the outer wall of the hanger 2 and slidably cooperates with the hanger 2. An insulating rod 3 is provided on one side of the ring 4, and an arc-shaped hanging plate is provided at the bottom of the insulating rod 3. Several lifting sleeves 61 are slidably cooperated on the insulating rod 3. Several insulating curved plates 31 for placing cables 200 are provided on one side of the lifting sleeve 61. The outer end of the insulating curved plate 31 is bent upward, and a blocking plate 311 is provided at the bottom of the insulating curved plate 31. A locking nut 62 for fixing the lifting sleeve 61 is threadedly connected to the insulating rod 3; At the very bottom, the arc-shaped hanging plate and the sealing plate 311 on the side of the adjacent upper lifting sleeve 61 cooperate to form a closed cavity; above the hanging plate, the insulating arc-shaped plate 31 on the side of the lower lifting sleeve 61 and the sealing plate 311 on the side of the adjacent upper lifting sleeve 61 cooperate to form a closed cavity. The sealing plate can cooperate with the adjacent insulating arc-shaped plate to prevent the cables from falling out of the insulating arc-shaped plate, ensuring the stable placement of the cables. The design of the lifting sleeve allows the insulating arc-shaped plate to be flexibly adjusted according to the height requirements of the cable, improving the applicability of the device; the locking nut can fix the position of the lifting sleeve, ensuring that the insulating arc-shaped plate will not move arbitrarily after being adjusted to the appropriate height, thus ensuring the stability of the device.

[0048] Example 5 On the basis of Example 1, the difference from Example 1 is that Figures 5 to 7 As shown, the insulating hook includes a hook body and a ring 4 provided on one side of the top of the hook body. The ring 4 is sleeved on the outer wall of the hanger 2 and slides with the hanger 2. An insulating rod 3 is provided on one side of the ring 4. The insulating rod 3 is provided with a plurality of insulating curved plates 31 for placing the cable 200. The insulating curved plate 31 is provided with a plurality of through holes, and a flexible plate 71 is provided on the outer wall of the insulating curved plate. The flexible plate 71 is fixedly connected to the bottom of the insulating curved plate 31 by a left bolt 73 and a right bolt 74. The outer wall of the insulating curved plate is provided with a plurality of threaded holes, which match the threads of the left bolt 73 and the right bolt 74. The flexible board 71 is provided with a plurality of ball grooves 711 , in which rolling balls 72 are arranged. After passing through the through holes, the rolling balls are higher than the upper surface of the insulating arc board.

[0049] The setting of the rolling ball changes the contact mode between the cable and the insulating curved plate from sliding contact to rolling contact, further reducing the resistance when the cable is dragged, making the cable dragging easier and smoother, improving construction efficiency, and also reducing the risk of cable damage due to friction; The introduction of the flexible plate allows for the left end of the flexible plate to be pulled down to the edge of the insulating arc plate below by loosening the left bolt when the cable does not need to be pulled again, and then tightened again with the left bolt to form a closed loop, effectively preventing the cable from falling from the insulating arc plate and improving the safety and reliability of the device.

[0050] To install temporary wiring on a construction site, first install a U-shaped clamp on the ceiling 100 and place the installation pipe 108 inside the U-shaped clamp. The clamp's ring 11 is then clipped onto the installation pipe 108 and secured with a first nut 13 and a first bolt 12. A hanger rod 2 is installed at the bottom of the ring 11, and a locking nut 21 is placed at the bottom of the hanger rod.

[0051] Select a suitable insulating hook according to actual needs and install it on the hanging rod 2. If you choose an insulating hook with a roller, put the ring 4 on the hanging rod 2, place the cable 200 on the insulating arc plate 31, and use the roller 53 to facilitate the dragging of the cable.

[0052] If you choose an insulating hook with a lifting sleeve 61 and a blocking plate 311, put the ring 4 on the hanging rod, adjust the position of the lifting sleeve 61 on the insulating rod 3, place the cable on the insulating arc plate 31, and fix the position of the lifting sleeve 61 with the locking nut 62, and use the blocking plate 311 to prevent the cable from falling.

[0053] If you choose an insulating hook with a ball 72 and a flexible plate 71, put the ring 4 on the suspension rod 2, place the cable on the insulating arc plate 31, and use the ball 72 to facilitate dragging the cable. When the cable does not need to be pulled again, loosen the left bolt 73, pull the left end of the flexible plate 71 down to the edge of the insulating arc plate below, and then tighten it again with the left bolt 73 to form a closed loop to prevent the cable from falling.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
