Abstract
The present invention discloses a hydraulic walking support. It includes base frame, top beam, four bar linkage mechanism, shielding beam, hydraulic system, lifting device and traveling device, in which the bottom portion of lifting cylinder is equipped with a roller. Said invention can reduce frictional force between the lifting cylinder and traveling lever when the support is moved, and can prolong the service life of lifting cylinder.
Description
Technical field
The present invention relates to a kind of supporting safeguard that is used for the process of coal mining tunnel, particularly relate to a kind of hydraulic bracket in step type.
Background technology
Hydraulic bracket in step type is the supporting of carrying out the tunnel in the process of coal mining, protects one of visual plant of personal device security.Mainly form by base, back timber, quadric chain, caving shield, hydraulic system, lifting appliance, push unit etc.
Chinese invention patent manual CN1082130C discloses a kind of hydraulic bracket in step type, adopts crossbeam to link together between two bases, and forms the bearing of passing oil cylinder.The passing oil cylinder is arranged between the base and is hinged on the described crossbeam.The piston rod of passing oil cylinder is connected with the pusher rod of installing in its lower section.Pusher rod and transporter are hinged.Lifting appliance is tried to stop people from fighting each other by lift cylinder, guiding device, U-shaped and is formed.Lift cylinder is bearing on the base up and down in two lateral guides movably, and tries to stop people from fighting each other by U-shaped with base and to be connected.Lift cylinder is supported on the pusher rod, is supporting the middle part that U-shaped is tried to stop people from fighting each other simultaneously.The piston rod of lift cylinder stretches out earlier the base front end is lifted in moving process, passes oil cylinder withdrawal promotion pusher rod then and moves forward.Because the support deadweight directly is pressed on the pusher rod by lift cylinder, and is sliding friction between lift cylinder and the pusher rod, its frictional force is very big, and it is also very serious to wear and tear.Though a removable cover lower than pusher rod hardness has been installed in this invention in the bottom of lift cylinder, because serious wear needs often to change, not only cause waste, use also very inconvenient, serious meeting to shorten the application life of lift cylinder.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of hydraulic bracket in step type, and the frictional force when it can reduce support and moves between lift cylinder and the pusher rod prolongs application life of lift cylinder.
For solving the problems of the technologies described above, hydraulic bracket in step type of the present invention comprises base, back timber, quadric chain, caving shield, hydraulic system, lifting appliance, push unit; Push unit comprises passes oil cylinder and pusher rod, adopts tie-beam to link together between two bases, and forms the bearing of passing oil cylinder, and the passing oil cylinder is arranged between the base and is hinged on the described tie-beam; The piston rod of passing oil cylinder is connected with the pusher rod of installing in its lower section; Pusher rod and transporter are hinged; Lifting appliance is tried to stop people from fighting each other by lift cylinder, guiding device, U-shaped and is formed, lift cylinder is bearing on the base up and down in two lateral guides movably, U-shaped is tried to stop people from fighting each other and is fixed on the base 6 by connecting pin, the bottom support of lift cylinder is on pusher rod, and its piston rod is supporting the middle part that U-shaped is tried to stop people from fighting each other; Wherein, be provided with a roller in the bottom of lift cylinder.
Because the present invention has set up roller in the bottom of lift cylinder, produce when relatively moving when lift cylinder and pusher rod like this, the existing glide friction is become rolling friction, can reduce the frictional resistance when support is passed, make lift cylinder the time greatly reduce transverse bending power, thereby prolonged the application life of lift cylinder and potted component thereof piston rod in action.
Description of drawings
The present invention is further detailed explanation below in conjunction with accompanying drawing and the specific embodiment:
Fig. 1 is the structural representation of hydraulic bracket in step type of the present invention;
Fig. 2 is the structural representation of lifting appliance among Fig. 1;
Fig. 3 is the structural representation of lift cylinder among Fig. 2.
The specific embodiment
As shown in Figure 1, hydraulic bracket in step type of the present invention comprises base 6, back timber 1, quadric chain, caving shield 2, hydraulic system, lifting appliance, push unit.
Described push unit comprises passes oil cylinder 4 and pusher rod 5.Two bases 6 are arranged in parallel, and make its fixedly connected being integral by tie-beam.Base 6 is provided with supporting top beam 1 adjustable for height column.Tie-beam is simultaneously as the bearing of passing oil cylinder 4, and passing oil cylinder 4 is arranged between two bases 6 and is hinged on the described tie-beam.Pusher rod 5 is installed in the below of passing oil cylinder 4, and the piston rod 3 of passing oil cylinder 4 is connected by connecting pin with an end of pusher rod 5.The other end of pusher rod 5 and conveyer 9 are hinged.
Referring to Fig. 2, described lifting appliance is tried to stop people from fighting each other by lift cylinder 14, guiding device, U-shaped and 11 is formed.Lift cylinder 14 is bearing on the base 6 by the guiding device 13 of both sides, and can move up and down in guiding device 13.U-shaped is tried to stop people from fighting each other and 11 is fixed on the base 6 by connecting pin 12.The bottom support of lift cylinder 14 is on pusher rod 5, and the piston rod 15 of lift cylinder 14 is fixed on U-shaped tries to stop people from fighting each other by bolt 10.
The cylinder body of described lift cylinder 14 is formed (in conjunction with Fig. 3) by two parts, sets up a cylinder body sole piece 16 below the cylinder body of original lift cylinder 14, and is fixed in by screw below the cylinder body of lift cylinder 14, is convenient to like this change in maintenance process.Cylinder body sole piece 16 is provided with a hemispheric recess, wherein is provided with a roller 17.Shrouding 18 has a circular hole, and roller 17 parts are passed this circular hole, then shrouding 18 are fixed by bolts on the cylinder body sole piece 16.
Hydraulic bracket in step type of the present invention is when moving movement, and piston rod 3 withdrawals of passing oil cylinder 4 make pusher rod 5 drive conveyer 9 and travel forward, and roller 17 rollings made between lift cylinder 14 and the pusher rod 5 and produced rolling friction this moment.
Lift when motion end, the piston rod 15 of lift cylinder 14 stretches out and promotes U-shaped and try to stop people from fighting each other 11, is upturned by U-shaped 11 front ends that drive bases 6 of trying to stop people from fighting each other.Lifting end motion finishes the piston rod 3 of passing oil cylinder 4 in the back and stretches out pusher rod 5 drive bases 6 are travelled forward.
