Abstract
The utility model relates to support equipment for coal mine exploitation, in particular to a 6.2m high hydraulic bracket with high safety performance, which solves the problems arising from the structure and design of the prior hydraulic bracket. The hydraulic bracket comprises a base, two hydraulic telescopic upright posts mounted on the base, an upper connecting rod, a lower connecting rod, a shield rack connected with the upper and the lower connecting rods, a top beam connected with the hydraulic telescopic upright posts, and a primary protective plate and a secondary protective plate connected in front of the top beam, wherein, a protective mesh is arranged between the two hydraulic telescopic upright posts, a safety valve draft tube is installed on the safety valve of the balance jack supporting the top beam, the front passage food board on the base sinks to be a groove, an anti-skid pattern is formed inside the groove, and an upper spacing block and a lower spacing block are arranged on the base and the hinge part of the upper connecting rod. The measures adopted in constructing the utility model substantially solve the problems arising from the usage of the hydraulic bracket, such as injection of liquid to people by the safety valve, injuries caused by slippery foot board and crushed coal and the like, and improve the safety performance of the hydraulic bracket.
Description
Technical field
The utility model relates to a kind of colliery underground mining support apparatus, is specially 6.2 meters hydraulic supports of a kind of high safety performance.
Background technology
Now significant advantage such as rate of extraction height, single stope output are big because large-mining-height working surface has, but production technology is simplified full-seam mining etc.So the large-mining-height skill is more and more used.Big mining height support is the key equipment of large-mining-height working surface, and whether the quality of its design can have influence on the face timbering state and then be related to work plane and can make smooth advances, and safe, the convenience of operation of personnel, equipment, the maintenance of support etc.Number of patent application is 2007200892748 to disclose a kind of hydraulic shield support, and this hydraulic support can roof supporting, solves roof cracking, problems such as coal wall caving, realize to breaking roof timely control, prevent roof collapse.This technology is applied in the down-hole, but finds that in use there are some flaws in this device.
Summary of the invention
The utility model provides a kind of high safety performance 6.2 meters hydraulic supports in order to solve some improper parts that exist in the existing hydraulic rack structure design.
The utility model is realized by following technical scheme, 6.2 meters hydraulic supports of a kind of high safety performance, comprise base, be installed in two hydraulically extensible columns on the base, last connecting rod, lower link, with last connecting rod, the cover frame that lower link connects, the back timber that is connected with the hydraulically extensible column, be connected the preceding one-level group backplate of back timber, secondary group backplate, be provided with protective screening between two hydraulically extensible columns, on the very heavy safety valve of the balance of supporting top beam the safety valve deflector be installed, sagging at the prepass pedal of base is groove, and in be provided with anti-skidding line, the rod hinge connection place of closing on base is provided with upper limit position block and lower position block.Pressure relief safety valve also is installed, and leakage hole prevents that down hydrojet from hurting sb.'s feelings on the hydraulically extensible column.
Compared with prior art, the utlity model has: 1, increase protective screening between two hydraulically extensible columns, can prevent that broken coal breakage piece from hurting sb.'s feelings.2, the prepass pedal is sunk be the groove shape, and in be provided with anti-skidding line, skid in the time of can preventing to walk.3, on the very heavy safety valve of balance, the safety valve mozzle is installed, can prevents that the high pressure drainage is sprayed onto on the person, the controller.4, each column is adorned 2 safety valves, has increased the protection to support safety.5, increased the connecting rod position-limit mechanism, the very heavy controller that damages by pressure of balance in the time of can preventing the support extreme lower position.By above measure, solved the safety valve drainage spray people that hydraulic support in use occurs basically, problem such as foot rest is sliding, broken coal is hurted sb.'s feelings has improved the security performance of hydraulic support.
