Description

Technical Field

[0001] The present application belongs to the technical field of cable laying, and in particular relates to a supporting device for cable laying. Background Art

[0002] When installing a power distribution cabinet, a cable trench is usually opened below the cabinet to facilitate the passage of cables in and out of the cabinet and to provide a certain degree of protection for the cables. Support frames are also installed at predetermined intervals within the trench to support the cables, preventing them from falling to the bottom of the trench and getting damp, which would reduce their service life. During the actual construction process, the cable trench must first be cast and formed. The support frame is installed by pre-embedding the base for installing the support frame during the casting process. After the cable trench is fully formed, the support frame is installed on the pre-embedded base by welding or bolting. However, during welding or bolting, it is found that the welded support frame is skewed or the bolts do not align with the threaded holes reserved on the base. Upon investigation, it was found that the cause of these problems is that the cable trench is generally constructed with bricks or cement, and the base is pre-embedded therein. After the cable trench is completely air-dried and formed, the position of the base will always be offset from the pre-embedded position, leading to the above-mentioned problems. In addition, the above-mentioned traditional support frame installation method is relatively cumbersome. The base needs to be pre-buried when making the cable trench. The support frame body can only be installed after the cable trench is fully formed. The cable can only be laid after the support frame is fully installed, resulting in a lengthy construction period. Utility Model Content

[0003] In order to solve the above-mentioned deficiencies of the prior art, the present application provides a support device for cable laying, which does not require a pre-buried base and is easy and quick to install.

[0004] In order to achieve the above purpose, the utility model adopts the following technologies:

[0005] A supporting device for cable laying, comprising:

[0006] There are two mounting frames, each of which has an anti-roll plate vertically connected to one end thereof, and both anti-roll plates face in the width direction of the mounting frames;

[0007] A plurality of support frames, each comprising a movable frame disposed in the mounting frame and movable along the length direction of the mounting frame, a guide rod disposed in the movable frame and extending in the length direction of the mounting frame, the guide rod being passed through two bearing plates perpendicular to the anti-roll plate, a first spring being sleeved on the guide rod, the first spring being connected between an inner end surface of the movable frame and the corresponding bearing plate;

[0008] The tightening mechanism is arranged between the two mounting frames, and includes an axle seat vertically connected to the two ends of one mounting frame. A push rod is coaxially arranged in the axle seat. The push rod is elastically telescopically arranged along its own axis. Matching holes for matching with the push rod are opened at both ends of the other mounting frame.

[0009] Furthermore, each mounting frame has strip holes on both sides along its width direction, and the length of the strip holes is adapted to the length of the mounting frame. The two sides of the movable frame are vertically connected with matching rods, which are respectively passed through the corresponding strip holes. One end of the matching rod is provided with an external thread for installing a locking nut.

[0010] Furthermore, arc grooves are evenly distributed along the length of the installation frame on both sides of the strip hole, and a matching plate that matches the arc grooves on both sides is sleeved on the matching rod between the external thread and the strip hole, and the thickness of the matching plate is greater than the depth of the arc groove.

[0011] Furthermore, a mounting hole is opened at one end of the shaft seat along the length direction, one end of the push rod passes through the mounting hole, a second spring is provided in the mounting hole, and the second spring is connected between the push rod and the bottom of the mounting hole.

[0012] The beneficial effects of the utility model are:

[0013] 1. The anti-tilt plates vertically connected at one end of the two mounting frames are used to stand the mounting plates on both sides of the cable trench. Through the setting of the tightening mechanism and the support frame, not only can the two mounting frames be tightly pressed against the two side walls of the cable trench, but the height of the load-bearing plate used to place the cables can be adjusted according to the actual laying requirements, thereby achieving the purpose of not needing to pre-embed the matrix when pouring the cable trench, simplifying the installation of the device, changing the traditional installation method of welding or bolt tightening, and achieving the purpose of laying cables while assembling the device after the cable trench is formed, greatly shortening the construction period of cable laying;

[0014] 2. By setting the strip holes, matching rods and arc grooves and coordinating with the locking nuts and matching plates, the mobile frame can be more firmly fixed in the installation frame after it is in the appropriate position. This not only effectively ensures the bearing effect of the load-bearing plate on the mobile frame on the cable and improves the reliability of the device, but also further simplifies the installation of the device and improves the efficiency of cable laying.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] The embodiment of the present application provides a supporting device for cable laying, such as Figures 1 to 3 As shown, it includes: a mounting frame 1, a support frame 2, and a tightening mechanism 3.

[0023] Among them, there are two mounting frames 1, one end of the two mounting frames 1 is vertically connected to the middle of the anti-roll plate 11, and the two anti-roll plates 11 are both facing the width direction of the mounting frame 1; in the embodiment, there are two support frames 2, which can carry more cables. The support frame 2 includes a movable frame 21 arranged in the mounting frame 1 and movable along the length direction of the mounting frame 1. A pair of guide rods 22 facing the length direction of the mounting frame 1 is provided in the movable frame 21. The guide rods 22 are passed through two bearing plates 23 perpendicular to the anti-roll plate 11. A first spring 24 is sleeved on the two guide rods 22, and the first spring 24 is connected between the inner end surface of the movable frame 21 and the corresponding bearing plate 23; a tightening mechanism 3 is provided between the two mounting frames 1, which includes an axle seat 31 vertically connected to the two ends of one mounting frame 1, and a push rod 32 is coaxially provided in the axle seat 31. The push rod 32 is elastically telescopically arranged along its own axis, and a matching hole 33 is opened at both ends of the other mounting frame 1 to match the push rod 32.

[0024] When in use, first adjust the position of the movable frame 21 according to the height of the cable laying. After the adjustment is completed, the installation frame 1 is placed on both sides of the cable trench through the anti-roll plate 11. Under the cooperation of the anti-roll plate 11 and the bottom of the cable trench, the installation plate 1 will not tilt to its sides. Then, the top rods 32 in the shaft seats 31 at both ends of one installation frame 1 are pressed toward the shaft seats 31, so that the two top rods 32 are respectively aligned with the matching holes 33 opened at both ends of the corresponding other installation frame 1. The pressed top rods 32 are released and pushed into the matching holes 33. Under the interaction of the top rods 32 on the two installation frames 1, the two installation frames 1 are tightly pressed against the inner walls on both sides of the cable trench. When the two mounting frames 1 are completely fixed, the cable is laid between the two bearing plates 23. Under the action of the first spring 24, the cable is clamped between the two bearing plates 23, which improves the stability of the bearing plates 23 on the cable. The above operation is repeated after a predetermined distance along the cable trench to install the next section of the device and lay the cable. Through the structural design of the device, the purpose of not needing to pre-embed the matrix when pouring the cable trench is achieved, which simplifies the installation of the device and has good installation stability, improves the cable laying efficiency, and at the same time achieves the purpose of laying the cable while assembling the device after the cable trench is formed, which greatly shortens the construction period of cable laying.

[0025] Specifically, such as Figure 1 、 Figure 2 、 Figure 4 As shown, each mounting frame 1 has strip-shaped holes 12 on both sides along its width. The length of the strip-shaped holes 12 matches the length of the mounting frame 1. Coupling rods 25 are perpendicularly connected to both sides of the mobile frame 21. The coupling rods 25 are inserted into the corresponding strip-shaped holes 12. One end of the coupling rods 25 is provided with an external thread for mounting a locking nut 26. During use, after adjusting the position of the mobile frame 21, the locking nut 26 is screwed into one end of the coupling rod 25, so that the locking nut 26 presses against the two sides of the mounting frame 1, thereby locking the position of the mobile frame 21. This not only ensures the tightening effect of the mobile frame 21, but also simplifies the fixing method of the mobile frame 21, which is conducive to improving the installation efficiency of the device.

[0026] After the cables are laid, the load plate 23 will be subjected to the weight of the cables for a long time. If the locking nuts 26 are screwed in and the two sides of the mounting frame 1 are pressed to fix the movable frame 21, the locking nuts 26 may become loose after a long period of use, thereby directly affecting the fastening effect of the movable frame 21. To solve the above problem, this embodiment proposes a preferred solution, which is as follows: Figure 4 and Figure 5As shown, arcuate grooves 121 are evenly distributed along the length of the mounting frame 1 on both sides of the strip hole 12. A mating plate 27 is sleeved on the mating rod 25 between the external thread and the strip hole 12 to mate with the arcuate grooves 121 on both sides. The thickness of the mating plate 27 is greater than the depth of the arcuate grooves 121. During use, the locking nut 26 is simply screwed in from one end of the mating rod 25, so that the locking nut 26 presses against the mating plate 27 and approaches the arcuate groove 121 until both ends of the mating plate 27 completely contact the bottom of the arcuate grooves 121 on both sides. The locking nut 26 is then tightened further to lock the mating plate 27 between the locking nut 26 and the arcuate groove 121. The mating between the mating plate 27 and the arcuate groove 121 secures the position of the movable frame 21. Even if the locking nut 26 is somewhat loose, as long as it can lock the mating plate 27 in the arcuate groove 121, the tightening effect of the movable frame 21 can be guaranteed, thereby effectively extending the service life of the device and improving the reliability of the device.

[0027] Specifically, such as Figure 5 As shown, a mounting hole 34 is defined along the length of one end of the shaft seat 31. One end of a push rod 32 extends through the mounting hole 34. A second spring 35 is disposed within the mounting hole 34 and is connected between the push rod 32 and the bottom of the mounting hole 34. The second spring 35 acts to allow the other ends of the two push rods 32 to rest tightly against the mating holes 33 defined at either end of the other mounting frame 1, allowing the two mounting frames 1 to rest more stably against the side walls of the cable trench, further enhancing the stability of the device support.

[0028] Preferably, Figure 2 and Figure 3 As shown, a cable duct 231 is provided on the opposite surfaces of the two supporting plates 23, and the cable duct 231 is oriented in the length direction of the anti-roll plate 11, so that the supporting plate 32 can not only support the cable, but also cooperate with the first spring 24 to bundle the cable, which is beneficial for clarifying the lines when laying the cables and facilitating subsequent maintenance.

[0029] Preferably, Figure 3 As shown, the opposite surfaces at one end of the two supporting plates 23 are configured as inclined surfaces, which facilitates placing the cable between the two supporting plates 23 and helps improve the cable laying efficiency.

[0030] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
