Description

Technical Field

[0001] The utility model relates to the technical field of cable fixing, in particular to a novel cable support for both laying out and fixing cables. Background Art

[0002] During tunnel construction, as mechanical equipment for tunnel excavation advances, the cables required for powering the equipment also need to follow up. Ordinary cable bracket hooks can only fix cables on the inner wall of the tunnel, and do not support the transmission of cables on the bracket. The current solution mainly uses the method of changing the cable hook into a pulley to achieve cable transmission on the bracket. This method often requires the design of a completely new cable bracket, resulting in high costs, and the cables are not convenient to fix later, and there is still a high degree of freedom on the bracket.

[0003] Chinese patent CN218771219U discloses a tunnel cable support that can be transmitted and clamped. The device includes a pulley block, a clamping device and a supporting structure. During the implementation of the device, the upper and lower pulley blocks are used to transmit the cable, and the left and right clamping devices are used to fix the cable. The adjustable spacing enables the universal function of cables with different wire diameters. The cable support has multiple exposed sliding and rolling motion modes. The reliability is greatly reduced in the smoke, dust and gravel environment of tunnel construction. It is difficult to maintain and needs to be completely dismantled. The device has a complex structure and many parts, and the cost is high when laying cables over long distances in tunnels. Utility Model Content

[0005] The technical solution of the utility model is achieved in this way:

[0006] A new type of cable support for both laying out and fixing cables comprises a fixed support and a conveying support, wherein the fixed support comprises a fixed upright plate, fixing holes are formed at both ends of the fixed upright plate, a triangular support frame is integrally formed on one side of the fixed upright plate, a lower clamping ring is fixed to the end of the triangular support frame away from the fixed upright plate, an upper clamping ring is hingedly fixed above the lower clamping ring, and the movable ends of the lower clamping ring and the upper clamping ring are fixed by bolts; the conveying support comprises a hanging frame, a supporting roller is rotatably mounted on the lower end of the hanging frame, a connecting stud is rotatably mounted on the middle part of the upper end of the hanging frame, a hook is fixed on the upper end of the connecting stud, the hook is hooked on the fixed support, an upper end of one side of the hanging frame is open, a sealing plate is hingedly mounted at the opening, and the end of the sealing plate away from the hinge axis is snapped together with the upper side wall of the hanging frame.

[0007] Furthermore, the triangular support frame and the fixed vertical plate are directly fixed with reinforcing ribs.

[0008] Furthermore, a wear-resistant sleeve is fixed on the inner wall of the lower clamping ring and the upper clamping ring which are in contact with the cable.

[0009] Furthermore, an anti-drop buckle is hingedly fixed at the hook mouth of the hook.

[0010] By adopting the above technical scheme, the beneficial effects of the utility model are as follows: when the electric tunnel construction moves forward, the cable is placed on the support rollers of the conveying support, so that the cable can be moved forward together with the construction power equipment, thereby solving the problem of tunnel power supply and being able to effectively complete the work of transmitting and fixing the cable; the cable bracket has a simple structure, is easy to install, has simple parts acquisition and low manufacturing difficulty, and reduces production costs.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-Figure 4 As shown, a new type of cable support for both laying out and fixing cables comprises a fixed support member 1 and a conveying support member 2. The fixed support member 1 is used to fix the cables. The fixed support member 1 comprises a fixed vertical plate 11. The fixed vertical plate 11 has fixing holes at both ends, one of which is a round hole and the other is a long slot hole, so as to be fixed to the inner wall of the tunnel by using expansion bolts. A triangular support frame 12 is integrally formed on one side of the fixed vertical plate 11 for supporting the cables. A lower clamping ring 14 is fixed to the end of the triangular support frame 12 away from the fixed vertical plate 11. An upper clamping ring 15 is hingedly fixed above the lower clamping ring 14. The movable ends of the lower clamping ring 14 and the upper clamping ring 15 are fixed by bolts. The clamping ring 15 can fix the cable; the conveying support 2 is used for the rapid conveyance of the cable, and the conveying support 2 includes a hanging frame 21, and a support roller 25 is rotatably installed at the lower end of the hanging frame 21, which is used to reduce friction so that the cable can be quickly and easily pushed forward along with the construction electrical equipment. A connecting stud 22 is rotatably installed in the middle of the upper end of the hanging frame 21, and a hook 23 is fixed at the upper end of the connecting stud 22. The hook 23 is hooked on the fixed support 1. The upper end of one side of the hanging frame 21 is open, and a sealing plate 26 is hingedly installed at the opening. The end of the sealing plate 26 away from the hinge axis is buckled with the upper side wall of the hanging frame 21, and the sealing plate 26 can be opened to facilitate the placement of the cable.

[0020] In this embodiment, in order to further increase the strength of the fixed support member 1, the triangular support frame 12 and the fixed vertical plate 11 are directly fixed with a reinforcing rib 13, and the hook 23 can be hooked on the lower clamping ring 14, or can be hooked between the triangular support frame 12 and the reinforcing rib 13 without affecting the normal fixing of the cable by the lower clamping ring 14.

[0021] In this embodiment, a wear-resistant sleeve 16 is fixed on the inner wall of the lower clamping ring 14 and the upper clamping ring 15 that contacts the cable. The wear-resistant sleeve 16 is preferably made of CR foam to prevent the cable from sliding and reduce the damage of the fixed support member 1 to the outer sheath of the cable. The thickness of the CR wear-resistant sleeve 16 is 0.5-1.0 mm.

[0022] In this embodiment, an anti-drop buckle 24 is hingedly fixed at the hook mouth of the hook 23 to prevent the conveying support member 2 from falling off the fixed support member 1 when the cable moves.

[0023] Preferably, the supporting roller 25 is a plastic roller with a minimum diameter of 40 mm, a maximum diameter of 70 mm, and a length of 80 mm. The hanging frame 21 is made of 5 mm thick stainless steel. The fixed support 1 is made of 6 mm thick aluminum alloy. The bolts connecting the lower retaining ring 14 and the upper retaining ring 15 and the bolts fixing the fixed vertical plate 11 are bolts of the same specifications, which facilitates subsequent installation operations without frequent replacement of tools.

[0024] The working principle of the utility model is as follows: when in use, the fixed support member 1 is fixed to the side wall of the tunnel by using expansion bolts, and then the conveying support member 2 is hooked on the fixed support member 1, and the cable is placed on the support roller 25 to facilitate the rapid movement of the cable. When the cable moves to the specified position, the sealing plate 26 can be opened, and then the cable is removed from the support roller 25 and the conveying support member 2 is removed. The cable is placed on the lower clamping ring 14 and the upper clamping ring 15 and fixed directly with bolts to complete the cable fixation.

[0025] Components not described in detail herein are prior art.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
