Description
Technical field
A kind of positive double leval jib hydraulic support of polytypic with Telescopic of the invention, belongs to hydraulic support technical field.
Background technique
In order to meet client (mine side), down-hole coal bed geological conditions and requirement design, produce a supporting height certainly
2.4m-3.7m, transition bracket of the working resistance in the positive double leval jib of four post support shield type low caving coal of 10000KN；It can be with
Supporting front, rear portion drag conveyor, and meet the requirement for having pedestrian space between the column of front and back；Often produced for mine Founder,
It mines and necessary equipment support is provided.
Summary of the invention
The present invention overcomes the shortcomings of the prior art, remarkable space is provided by foot pedal between the column of front and back,
Supporting effect when flexible girder construction can play interim zero, face guard may be reversed, and carry out supporting to relatively more broken top coal or rock.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention are as follows: face guard may be reversed, to what is be relatively crushed
Top coal or rock carry out immediate support, play the role of preventing wall caving, the cant beam composition double leval jib of front and rear connecting rods and pedestal to coal wall
Mechanism enhances the ability of whole horizontal force resistant and anti-torsion, and caving shield, tail boom, plate and waste rock board protect rear portion transporter,
Guarantee certain underneath clearance；And the function of rear portion transporter is protected by the flexible realization of tail boom swung up and down with plate,
By the revolution of the very heavy flexible realization waste rock board of gear cash, the rear portion support space of bracket is increased, can preferably supporting be set
Standby and ad hoc inspection and repair personnel.
Compared with the prior art, the invention has the beneficial effects that: the top beam for providing radial type structure type adapts to
The situation adaptability of top plate injustice is good；Positive four-bar linkage structure, which realizes, provides remarkable space between the column of front and back；Realize that band is stretched
Contracting girder construction interim zero when protective function；Face guard may be reversed, and carry out immediate support to relatively more broken top coal or rock, right
Coal wall plays the role of preventing wall caving；Top beam, caving shield movable side protection plate structure are added, adjacent frame waste coal and corresponding tune are protected
The effect of frame.
