Abstract
The present invention, which provides, a kind of can be used to the parts such as novel clamping apparatus, including pedestal, shaft, cover board and fastener of leaky cable in fixed Railway Tunnel.Fixture is fixed on tunnel wall surface by bolt and hexagonal internal screw thread stud when use, by leaky cable as rear cover closing lid plate in fixture pedestal, fastener insurance is opened, completes the fixation of leaky cable.The present invention is by designing a new leakage cable fixture, it can bear the shock loading for the Piston Action Wind that the train of higher overall trip speed generates in tunnel, unique fastener structure can prevent cable in use process from falling off, anchoring engaging structure can solve the problems, such as the whole transfer in use of existing fixture, have higher safety and reliability.
Description
Technical field
The invention belongs to mechanical engineering fields, and in particular to a kind of for fixing leaky cable in Railway Tunnel
Fixture.
Background technique
Leaky cable is the important equipment of high speed rail system, is the best mode that high-speed railway communicates in tunnel, and
Holding clamp is the unique scheme being fixed on leaky cable in high-speed rail tunnel.But with the continuous improvement of train operation speed,
Also more acutely, existing fixture structure will be no longer applicable in the impact of generated Piston Action Wind train when running in tunnel.At present
The leaky cable holding clamp of domestic each deposit is only used for 350 kilometers and runs speed per hour below, has no relevant to speed-raising
Matched fixture technical solution, therefore this kind of technical solution need to be laid in advance.And in practical projects, there is cables for existing fixture
Handling are inconvenient, anchor the problems such as transfer, high temperature embrittlement.Therefore, study that a kind of applicable speed is fast, intensity is high, height easy to use
Fast railway tunnel leakage cable fixture can also be improved railway auxiliary facility state to China railways speed-raising important in inhibiting is supported
Productionization degree.
Summary of the invention
It is an object of the invention to overcome the problems, such as the prior art be applicable in speed it is low, using difficulty, provide a kind of novel
Railway Tunnel leakage cable fixture is able to bear the Piston Action Wind shock loading generated when higher speed per hour train operation, more square
Just worker installs and unloads cable.
Above-mentioned purpose of the invention realizes that dependent claims are to select else or have by the technical characteristic of independent claims
The mode of benefit develops the technical characteristic of independent claims.
To reach above-mentioned purpose, the technical solution adopted in the present invention is as follows:
A kind of Railway Tunnel leaky cable holding clamp, which is characterized in that including pedestal, shaft, cover board and fastener.
Fixture is fixed on tunnel wall surface by bolt and hexagonal internal screw thread stud, leaky cable is closed as rear cover in fixture pedestal
Cover board opens fastener insurance, completes the fixation of leaky cable.By designing a new leakage cable fixture, can bear higher
The shock loading for the Piston Action Wind that the train of overall trip speed generates in tunnel, unique fastener structure can prevent electric in use process
Cable falls off, and anchoring engaging structure can solve the problems, such as the whole transfer in use of existing fixture, has higher safety and can
By property, in which: pedestal includes stiffener plate, cable card slot and positioning screw hole.Positioning screw hole is used for positioning stud, prevents fixture whole
Body transfer；Card slot is for placing cable；Stiffener plate is used to improve the reliability and security of fixture.
Cover board includes buffer substrate tablet and outer hook.Buffer substrate tablet prevents cable because of generation when train passes through for fixing cable position
Piston Action Wind and shake, and play cushioning effect；Outer hook is used for and fastener cooperation carries out the fixed cable of locking.
Buckle includes safety device and buckling device, and buckling device is used to cooperate fixed cable, insurance with the fastener of cover board
Device is used to prevent fixture to be opened accidentally because of non-artificial factor after fastener fastening.
Shaft is used for chain connects cover plate and pedestal, opens and closes convenient for fixture.
In further embodiment, a kind of Railway Tunnel leaky cable holding clamp has positioning spiral shell simultaneously
Hole can cooperate with the hexagonal internal screw thread stud of standard and be fixed.
In further embodiment, a kind of Railway Tunnel leaky cable holding clamp setting buffer substrate tablet, one
Aspect can fix cable, and buffer function on the other hand can be played when train is shaken by cable.
In further embodiment, there is a kind of Railway Tunnel leaky cable holding clamp insurance to tie simultaneously
Structure can prevent it from causing cable surprisingly to fall off because of non-artificial factor at work；
In further embodiment, a kind of Railway Tunnel leaky cable holding clamp is equipped with stiffener plate,
Fixture overall structural strength is improved, prevents from being broken in engineering because of the impact of Piston Action Wind.
The invention has the benefit that the present invention can bear higher operation by designing a new leakage cable fixture
The shock loading for the Piston Action Wind that the train of speed generates in tunnel, unique fastener structure can prevent cable in use process de-
It falls, anchoring engaging structure can solve the problems, such as the whole transfer in use of existing fixture, have higher safety and reliability

Specific embodiment
In order to better understand the technical content of the present invention, special to lift specific example and illustrate appended by cooperating as follows.
As shown above, Railway Tunnel leaky cable holding clamp is by pedestal 1, cover board 2, shaft 4 and 10 groups of fastener
At.Cover board and pedestal are attached by shaft 1, shaft 2 52, setting retaining spring 7 and shaft 6 in fastener, on buckle 8
Safety device 9 is set.
Wherein, pedestal 1 is for placing leaky cable；Buckle 8 passes through and cover board 1, the cooperation of cover board 2 32 carry out cable
It is fixed；Retaining spring 7 make buckle 8 keep buckling state, safety device by on pedestal locating piece cooperate, prevent fixture because
Non-artificial factor is opened accidentally.
Using above-mentioned high-speed railway leaky cable holding clamp, the working efficiency of leaky cable handling is improved, supports China
The further speed-raising of high-speed railway improves me and crosses the degree domestic of high-speed railway auxiliary facility.
As alternative embodiment, as shown in figure 4, having positioning device on bottom plate, can cooperate with hexagonal internal screw thread stud, when
When fixture is fixed on tunnel wall surface, whole transfer phenomenon will not occur.
As alternative embodiment, as shown in Figure 1, buffer substrate tablet is used to fix cable position, when preventing cable from passing through because of train
The Piston Action Wind of generation and shake, and play cushioning effect.
As alternative embodiment, as shown in figure 5, have safety structure simultaneously, can prevent its at work because it is non-artificial because
Element and cause cable surprisingly to fall off.
As alternative embodiment, as shown in figure 4, being equipped with stiffener plate, fixture overall structural strength is improved, is prevented in engineering
It is middle to be broken because of the impact of Piston Action Wind.
