Abstract
The utility model provides a kind of anti-down fixing device of individual hydraulic prop, including drilling steel plate, band ear clip, and the band ear clip is fixedly connected by two band ear semicircle cranses by fastener；The drilling and is welded into together steel plate with ear clip, and the setting direction of the drilling steel plate is mutually perpendicular to the setting direction with ear clip.The anti-down fixing device of the mine individual hydraulic prop is compared to the prior art, it is repeatable utilize, it is easy for installation, carry that transport is convenient, it is integrated, safe and reliable to install simple, connection effect, this monomer fixation instead of the epoch with square wood strip and iron wire securing unit, it is practical, it is applied widely, it is easy to promote.
Description
Technical field
The utility model is related to mining equipment technical field, specifically a kind of monomer simple in construction, practical
The anti-down fixing device of hydraulic prop.
Background technology
It is suffered when the hydraulic prop installed in advance in the crossheading of underground coal mine coal-face two is not connected with each other
Power source only top plate and bottom plate give, and top plate and bottom plate can only be stressed upon single vertical direction to his unidirectional force, this
Just the possibility of force unbalance is easily produced, if top plate and bottom plate give the dynamics of individual prop not in the presence of crustal stress
Balance, individual prop stand will disequilibrium and produce individual prop and fall, working face holdee will be produced very big
Potential safety hazard, then must on monomer plus a kind of stability of standing that can reinforce individual prop can ensure that individual prop again
To the hard link of the supporting effect of roof and floor.
Conventional hard link is to coordinate iron wire binding monomer to connect with square wood strip.Square wood strip pole in the moist environment in underground
Perishable and be broken off, the iron wire of binding monomer is non-reusable during monomer changes branch, and tunnel overall image not
It is attractive in appearance.Cause substantial amounts of fee of material to put into and unnecessary waste, disagreed with setting up economizing type mine.
Based on this, a kind of overall appearance, the hydraulic single strut anti-collapse fixing device of fixation are now provided.
The content of the invention
The problem of in order to overcome existing anti-down technology, it is proposed that a kind of hydraulic single prop interlocks tilting prevention device, described
Monomer independent one by one is combined together by device, forms a support system, increases security performance, ensures workmen's peace
Entirely.
The technical solution of the utility model realizes that a kind of anti-down fixation of individual hydraulic prop is filled in the following manner
Put, including drilling steel plate, band ear clip, the band ear clip by two band ear semicircle cranses be fixedly connected by fastener；
The drilling and is welded into together steel plate with ear clip, and the setting direction of the drilling steel plate and the setting direction with ear clip are mutual
Vertically.
In the above-mentioned technical solutions, by that by being fixedly installed for being welded to form with ear clip and drilling steel plate, can realize
The integration of connection effect, the horizontal securing unit of band ear clip, it is ensured that individual prop will not disequilibrium easily, high safety,
Ensure the stability of standing of individual prop, it is ensured that hard link of the individual prop to the supporting effect of roof and floor.
Preferably, the fastener includes two fixed plates and brill for being arranged on two cranse ends and stretching out
The positioning through hole that hole steel plate is carried is used cooperatively with screw nut assembly.The fastener structure of the structure is simpler, Gu
It is fixed more to facilitate, and dual fixation, screw rod need to only be fixed through fixed positioning through hole, plus nut when using, it is practical
Property is strong.
The anti-down fixing device of a kind of mine individual hydraulic prop of the present utility model has simple in construction, easy to use, structure
The features such as thinking ingenious, reasonable in design, the device is repeatable to be utilized, it is easy for installation, carry that transport is convenient, it is simple to install, connection effect
Really integrated, safe and reliable, this monomer fixation instead of the epoch with square wood strip and iron wire securing unit, practical, fit
With in extensive range, it is easy to promote.

Accompanying drawing 2 is overlooking surface structural representation of the present utility model.
Accompanying drawing 3 is Fig. 2 left view.
Accompanying drawing 4 is use state schematic diagram of the present utility model.
Accompanying drawing 5 is Fig. 4 left view.
Mark in accompanying drawing 4 is represented respectively：1st, drill steel plate, and 1.1, drilling steel plate positioning hole, 2, band ear clip, 2.1, band
Ear clip positioning hole, 3, hydraulic prop.
Embodiment：
A kind of anti-down fixing device of individual hydraulic prop of the present utility model is made in detailed below below in conjunction with the accompanying drawings
Explanation.
As shown in accompanying drawing 1, Fig. 2, Fig. 3, a kind of anti-down fixing device of individual hydraulic prop, including drilling steel plate 1, band
Ear clip 2, the band ear clip passes through clip positioning hole 2.1 by screw rod, and securing unit hydraulic prop is reached with the use of nut.
As shown in accompanying drawing 1, Fig. 2, Fig. 3, the drilling steel plate positioning hole 1.1, band ear clip positioning hole 2.1 are both sides up and down
Rounded strip hole.
The setting direction of drilling steel plate is mutually perpendicular to the setting direction with ear clip as shown in Figure 2, two drilling steel
Placed up and down between plate, the positioning through hole opened up by screw nut assembly through two drilling steel plates is tightly fixed, reaches monomer
The anti-down purpose of hydraulic prop.
