Abstract
The utility model discloses a novel canopy lifting device for a heading machine. The device comprises a heading machine cutting part protection cylinder, a base, a connecting base, a beam lifting arm, a beam supporting claw and a fine-adjusting oil cylinder, wherein the base is welded on the heading machine cutting part protection cylinder and connected with the connecting base; the beam lifting arm is mounted on the connecting base; a front hole and a rear hole are formed in the top of the connecting base; the front hole is used when the novel canopy lifting device is in use, and the beam lifting arm is overturned and locked on the rear hole of the connecting base through a pin shaft when the novel canopy lifting device is not used; the beam supporting claw is mounted at the front end of the beam lifting arm; and a cylinder diameter base of the fine-adjusting oil cylinder is welded on the beam lifting arm, and a rod diameter base is welded on the beam supporting claw. According to the novel canopy lifting device for the heading machine, the borehole operation efficiency of an operator is improved, and the safety coefficient during operation is increased.
Description
Technical field
The utility model relates to a kind of driving face in coal mine marguise support technology, relates in particular to the novel marguise device of a kind of development machine in colliery.
Background technology
Colliery at present, the use of development machine is very general, and development machine, in carrying out tunnelling, also has the function of auxiliary shoring operation, and the device of bringing into play this function is exactly Bracket for supporting roof beam.
General development machine Bracket for supporting roof beam is arranged on cut reduction box, in the time carrying out auxiliary shoring operation with development machine, exist certain defect, sometimes cutting head of roadheader is risen, cutterhead has arrived top, tunnel, and the U-shaped canopy of provoking cannot rise to required height, such Bracket for supporting roof beam is very impracticable.
Utility model content
In order to solve the existing problem of background technology, the utility model provides a kind of development machine novel marguise device, and it had both improved underground operators operating efficiency, the safety factor while increasing operation again.
For addressing the above problem, the utility model adopts following technical scheme:
The utility model provides a kind of development machine novel marguise device, and described device comprises cutting part of heading machine protection cylinder, base, Connection Block, outrigger arm, joist pawl and fine setting oil cylinder; Described base is welded on cutting part of heading machine protection cylinder; Described Connection Block is connected with base, and described outrigger arm is arranged on Connection Block, and Connection Block top is provided with former and later two holes, uses front hole when use, and the not used time, upset outrigger arm, is latched in outrigger arm on Connection Block metapore with bearing pin; Described joist pawl is arranged on outrigger arm front end; The cylinder diameter base of described fine setting oil cylinder is welded on outrigger arm, and bar footpath base is welded on joist pawl.
Described Connection Block and base are sewed up with high-strength bolt.
Described outrigger arm is arranged on Connection Block by bearing pin.
The utility model is arranged on Bracket for supporting roof beam on the flexible protection cylinder of cutterhead; can move along with the flexible of cutting head of roadheader like this; one fine setting oil cylinder is installed on Bracket for supporting roof beam; the effect of fine setting oil cylinder is the U-shaped canopy position to provoking and highly finely tunes; in height reach more accurately and regulate; thereby reach required ideal position, be convenient to the operation of development machine auxiliary shoring.
The novel marguise device of the utility model development machine, cost of manufacture is low, practical, has both improved underground operators operating efficiency, the safety factor while increasing operation again.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure, 1 is cutting part of heading machine protection cylinder; 2 is base; 3 is Connection Block; 4 is outrigger arm; 5 is fine setting oil cylinder; 6 is joist pawl.
Detailed description of the invention
Further illustrate the technical scheme of the utility model embodiment below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, be the novel marguise device of the utility model development machine, comprise cutting part of heading machine protection cylinder 1, base 2, Connection Block 3, outrigger arm 4, fine setting oil cylinder 5 and joist pawl 6.
Base, is welded on cutting part of heading machine protection cylinder upper, can be flexible along with cutterhead, move forward and backward;
Connection Block, sews up with 4 high-strength bolts with base, thereby can be flexible along with cutterhead, moves forward and backward;
Outrigger arm, is arranged on Connection Block with bearing pin, and You Liangge hole, Connection Block top, uses front hole when use, and the not used time, upset outrigger arm, is latched in outrigger arm on Connection Block metapore with bearing pin;
Joist pawl, is arranged on outrigger arm front end;
Fine setting oil cylinder, cylinder diameter base is welded on outrigger arm, and bar footpath base is welded on joist pawl.
It is upper that the novel marguise device of the utility model development machine is arranged on cutting units protection cylinder, can be flexible along with cutterhead, move forward and backward; By tunneling machine hydraulic system, install an adjusting oil cylinder additional, in height reach more accurately and regulate, negated the adjusting of former marguise device fixed journey system.
The novel marguise device of the utility model development machine, cost of manufacture is low, practical, has both improved underground operators operating efficiency, the safety factor while increasing operation again.
Finally it should be noted that: obviously, above-described embodiment is only for the utility model example is clearly described, and the not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also giving exhaustive to all embodiments.And the apparent variation of being amplified out thus or variation are still among protection domain of the present utility model.
