Description
Technical Field
The invention relates to the field of tunnel fire prevention, in particular to a cable tunnel fire prevention vertical plate fixing mechanism capable of being quickly assembled and disassembled and used in a cable tunnel.
Background
In recent years, power failure accidents caused by high-voltage cable faults frequently occur, wherein the situation that a common tunnel cable is ignited by grounding electric arcs in a cable tunnel sometimes occurs, equipment damage caused by the secondary accidents is more serious, the rush repair work is more time-consuming, and the power failure area is larger.
For preventing the occurrence of such secondary accidents, the existing protection measures are to fix the vertical fireproof partition plate on a cable support on one side by using bolts so as to carry out fireproof isolation on cables on two sides. Although the fire prevention riser can effectively keep apart both sides cable, prevents the intensity of a fire to spread to the opposite side when the conflagration takes place, but also brought a lot of difficulties for fortune dimension work simultaneously: 1. the operation and maintenance personnel need to disassemble and assemble the fireproof vertical plate when performing work such as inspection, emergency repair and the like, the original fireproof vertical plate is fixed and spliced by bolts, a large number of bolts need to be loosened and tightened in the disassembling and assembling process, and the working efficiency and the emergency repair efficiency are greatly reduced; 2. after the fireproof vertical plate is repeatedly disassembled and assembled, cracks can gradually appear at the bolt perforation position of the fireproof vertical plate, so that the vertical plate is loosened, even cracked and damaged, and the longitudinal fireproof isolation effect is lost. Therefore, it is necessary to develop a fire-proof fixing mechanism which is convenient for operation and maintenance personnel to assemble and disassemble and does not influence the mechanical strength of the fire-proof vertical plate after repeated assembly and disassembly.
Disclosure of Invention
Aiming at the problems, the invention provides the fireproof vertical plate fixing mechanism which is convenient to operate, can realize quick assembly and disassembly and can not influence the mechanical strength of the fireproof vertical plate after repeated assembly and disassembly.
In order to achieve the above object, the present invention provides a fast detachable cable tunnel fire-proof vertical plate fixing mechanism, which comprises: the fireproof vertical plate and the fixed support; two handrails are symmetrically arranged in the middle of the front side of the fireproof vertical plate; metal wrapping edges are arranged on four side faces of the fireproof vertical plate; two cross braces are horizontally arranged on the back of the fireproof vertical plate, two ends of each cross brace are connected with the metal wrapping edges on the side faces of the fireproof vertical plate, and two hooks are symmetrically arranged on the cross braces; the fixed support comprises a cable support and a horizontal keel.
In a preferable mode, the cable support is formed by connecting a support in the horizontal direction and a support in the vertical direction, and two layers of horizontal keels are horizontally arranged at the front end of the support in the horizontal direction.
In an optimal mode, the distance between the cross braces is the same as that between the horizontal keels, and the thickness of each horizontal keel is slightly smaller than the width of the notch of each hook.
In an optimal mode, when the notch of the hook is clamped on the horizontal keel, the fireproof vertical plate is fixed on the fixed support.
The invention has the beneficial effects that: the hanging fixing mode is adopted to replace the original bolt fixing mode, the fireproof vertical plate is convenient to disassemble and assemble, meanwhile, bolt perforation is avoided, and the mechanical strength of the fireproof vertical plate is improved.

Detailed Description
As shown in fig. 5, the present invention provides a fast detachable cable tunnel fire-proof vertical plate fixing mechanism, which includes: a fireproof vertical plate 1 and a fixed bracket 2; two handrails 3 are symmetrically arranged in the middle of the front surface of the fireproof vertical plate 1; metal wrapping edges 4 are arranged on four side faces of the fireproof vertical plate 1; two cross braces 5 are horizontally arranged on the back of the fireproof vertical plate 1, two ends of each cross brace 5 are connected with the metal wrapping edges 4 on the side surfaces of the fireproof vertical plate 1, and two hooks 6 are symmetrically arranged on the cross braces 5; the fixing bracket 7 comprises a cable bracket 8 and a horizontal keel 9.
As shown in fig. 3, metal covering edges 4 are installed on four side surfaces of the fireproof vertical plate 1, so that the mechanical strength of the fireproof vertical plate 1 can be effectively improved, and the fireproof vertical plate 1 is prevented from cracking and raising edges; simultaneously, 6 stulls at place 5 lug connection of couple are on metal bordures 4, avoid the bolt perforation on fire prevention riser 1, further promote the mechanical strength and the fire behavior of fire prevention riser 1.
As shown in fig. 2, two handrails 3 are symmetrically installed in the middle of the front side of the fire-proof vertical plate 1, so that the fire-proof vertical plate 1 can be conveniently assembled and disassembled by an operation and maintenance worker, and the fire-proof vertical plate is suitable for being operated by both hands of a single person or two persons.
As shown in fig. 4, the cable support 8 is formed by connecting a horizontal support and a vertical support, and two layers of horizontal keels 9 are horizontally installed at the front end of the horizontal support.
As shown in fig. 1 and 4, the distance between the crossbars 5 is the same as the distance between the horizontal keels 9, the thickness of the horizontal keels 9 is slightly smaller than the width of the notches of the hooks 6, so that the installation and disassembly processes of the fireproof vertical plate 1 are smooth, the installation of the fireproof vertical plate 1 is firm, and the looseness of the fireproof vertical plate 1 is avoided.
When the fireproof hanging plate is used, the position of the fireproof vertical plate 1 is adjusted, and when the notch of the hook 6 is clamped on the horizontal keel 9, the fireproof vertical plate 1 is fixed on the fixed support 2; when the fireproof vertical plate 1 is lifted upwards, the notch of the hook 6 is separated from the horizontal keel 9, and the fireproof vertical plate 1 can be detached.
Traditional fire prevention riser all adopts bolt fastening, concatenation, and the dismouting in-process needs the pine, tightly a large amount of bolts, greatly reduced work prescription and salvage efficiency, moreover, fire prevention riser through relapse the dismouting back, crackle can appear gradually in its bolt perforation position, lead to the riser not hard up, fracture, damage even to vertical fire prevention isolation's effect has been lost. Through the improvement of the invention, the original bolt fixing mode is replaced by the suspension fixing mode, so that the efficiency of operation and maintenance personnel in the processes of inspection, rush repair and the like is greatly improved, and the adverse effect of bolt perforation on the protection performance of the fireproof vertical plate is avoided.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
