Description
Technical field
The present invention relates to a kind of colliery two column hydraulic supports, more particularly to a kind of two column hydraulic pressure branch of dibit balance jack
Frame.
Background technology
As shown in Figure 1, the position of two columns hydraulic support balance jack of the prior art is protected type balanced controls, put down
Weighing apparatus jack is supported between top beam and caving shield, and position is fixed, single position.
The shortcomings that above-mentioned prior art is：
Protected type balanced controls form stent and cut the pulling force that top power relies on jack, and stent cuts top power deficiency, and stent holds
Antiaircraft gun state of beating easily is formed, to the bad adaptability of roof and floor condition when especially low level is mined.When stent needs raising stent to cut
Power is pushed up, when preventing that stent formation from beating antiaircraft gun state, the adjustment capability deficiency of stent state, can only increase balance jack, imitate
Fruit unobvious.
The content of the invention
The object of the present invention is to provide a kind of two column hydraulic support of dibit balance jack.
The purpose of the present invention is what is be achieved through the following technical solutions：
The present invention two column hydraulic support of dibit balance jack, including top beam, column, caving shield, base, front rod,
Back link and balance jack, are respectively equipped with hinge joint, one end of the balance jack on the top beam, caving shield and base
With hinged point articulated on top beam, the other end can be cut with scissors with hinged point articulated on base but also with the hinge joint on caving shield
Connect.
As seen from the above technical solution provided by the invention, dibit balance jack two provided in an embodiment of the present invention
Column hydraulic support, brace type are used interchangeably with protected type balanced controls, while are transposed auxiliary cylinder support shield with fixed sliding block
Beam, that improves stent cuts top power, prevents stent is formed from beating antiaircraft gun state, enhances the adjustment capability of stent state, improve
To the adaptability of roof and floor condition when low level is mined.

Embodiment
The embodiment of the present invention will be described in further detail below.What is be not described in detail in the embodiment of the present invention is interior
Appearance belongs to the prior art known to professional and technical personnel in the field.
The two column hydraulic support of dibit balance jack of the present invention, its preferable embodiment are：
Including top beam, column, caving shield, base, front rod, back link and balance jack, the top beam, caving shield and
It is respectively equipped with hinge joint on base, hinged point articulated on one end and top beam of the balance jack, the other end can be the bottom of with
Hinged point articulated on seat but can with it is hinged point articulated on caving shield.
When hinged point articulated on the other end and base of the balance jack, the balance jack is covered with described
Security protection jack is equipped between guard beam.
Between the lower tie point of lower tie point and back link that hinge joint on the base is arranged on the front rod.
Two column hydraulic support of dibit balance jack provided in an embodiment of the present invention, the position of balance jack is dibit,
Changeable type uses protected type balanced controls or brace type balanced controls.Stent sets two link positions, one is screening
Liang Shang, the second is on base.When using brace type balanced controls, while protection jack safe to use.
Specific embodiment：
As shown in Figure 1, the position of protected type balanced controls is located on caving shield.Protected type balanced controls formed cut top power according to
By the pulling force of jack.
As shown in Fig. 2, brace type balanced controls, which are formed, cuts the thrust that top power relies on jack, by balance jack and shielding
The lower hinge of beam connection, is changed to be connected with base.Brace type balanced controls, can improve the supporting intensity of stent and cut top power.
What brace type balanced controls improved stent cuts top power, prevents stent is formed from beating antiaircraft gun state, enhances stent
The adjustment capability of state, improves when low level is mined to the adaptability of roof and floor condition.Brace type and protected type balance transposition behaviour
Make, ensure operating space in frame.Link position is placed on base, caving shield dorsal horn can be increased, improve and cut top power etc..
As shown in figure 3, when brace type is with protected type balanced controls ex-situ operations, it is with fixed sliding block tune to take safety measures
Position auxiliary cylinder (security protection jack) support shield beam.With fixed sliding block positioning auxiliary cylinder support shield beam, improve
Stent cuts top power, prevents stent formation from beating antiaircraft gun state and playing booster action, enhances the adjustment capability of stent state,
Improve when low level is mined to the adaptability of roof and floor condition.
Formed using brace type balanced controls and cut the thrust that top power relies on jack, balance jack is connected with caving shield
Lower hinge, be changed to be connected with base.Such a brace type balanced controls, can improve the supporting intensity of stent and cut top power, solve
Determine existing issue.And with sliding block positioning auxiliary cylinder support shield beam is fixed, ensure the reliability of such a mode.
Brace type and protected type balanced controls ex-situ operations, are respectively adopted different link positions, improve cutting for stent
Power is pushed up, prevents stent is formed from beating antiaircraft gun state, enhances the adjustment capability of stent state, is improved when low level is mined to pushing up bottom
The adaptability of slat element.
Brace type is general with linking the parts such as axis pin at protected type balanced controls two, ensures to use smoothness, securely and reliably.
Brace type and protected type balanced controls ex-situ operations, are respectively adopted different link positions, improve cutting for stent
Power is pushed up, prevents stent is formed from beating antiaircraft gun state, enhances the adjustment capability of stent state, is improved when low level is mined to pushing up bottom
The adaptability of slat element.
Specific data are as follows：
Brace type and protected type balanced controls ex-situ operations, single any type occupation mode, effect cannot all perform to
It is maximum.Only brace type is used interchangeably with protected type balanced controls, while is transposed auxiliary cylinder support shield beam with fixed sliding block,
Stent could be improved cuts top power, prevents stent is formed from beating antiaircraft gun state, enhances the adjustment capability of stent state, improve
To the adaptability of roof and floor condition when low level is mined.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art is in the technical scope of present disclosure, the change or replacement that can readily occur in,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of claims
Subject to enclosing.
