Specific embodiment
The utility model embodiment will be described in further detail below.Do not make in the utility model embodiment in detail
The content of description belongs to the prior art well known to professional and technical personnel in the field.
The high stability high-adaptability overlength supported laneway end support of the utility model is equipped, and is preferably embodied
Mode is:
Including pedestal, top beam, caving shield, the top beam includes the preceding top beam and rear top beam being hinged, the rear top beam
Rear end and the caving shield it is hinged and be supported on pedestal by rear column, the preceding top beam passes through double parallel upright supports and exists
On pedestal, the front end of the preceding top beam is hinged with revolution top beam, and the front end of the revolution top beam is hinged with revolution front-axle beam.
It is connected with balance jack between the preceding top beam and rear top beam, is connected between the revolution top beam and preceding top beam
Top beam jack is turned round, revolution front-axle beam jack is connected between the revolution front-axle beam and revolution top beam.
The revolution top beam is equipped with bottom limiting device.
The revolution top beam jack is using loxosis arrangement in cabinet.
The lower end of the caving shield is connect by front rod and back link with the pedestal.
The high stability high-adaptability overlength supported laneway end support of the utility model is equipped, and tunnel face end support is increased
It, being capable of substantially completely supporting machine head device to the supporting length of top plate；In the longer-range to roof timbering, it can satisfy
Ceiling does not adapt to adaptability；The stability for guaranteeing tunnel face end support, realizes the essential safety of security protection；Improve bracket
Supporting intensity increases bracket front end to the supporting power of top plate.
Specific embodiment:
It is as shown in Figure 3:
Tunnel end support equipment, pedestal use integral form, and top beam is using three-stage, longitudinal seperated articulated form, top
Beam front end is equipped with revolution front-axle beam, and using double leval jib stabilizing mechanism, using three support posts, a rear column is supported on rear top beam
On, before the front column of two parallel arrangements is supported on top beam.Beam structure is constituted from front to back successively are as follows: revolution front-axle beam returns
Turn top beam, preceding top beam and rear top beam.
Technical solutions of the utility model bring the utility model has the advantages that
1, as shown in figure 4, set cap supporting length is up to 10 meters or so, chain-drive section electromechanics can be protected to set completely substantially
It is standby.
2, set cap is hingedly made of revolution front-axle beam, revolution top beam, preceding top beam, four part of rear top beam, can adapt to
Topmast shield is connect to not ceiling.
3, bracket is supported using three root posts, and a root post leans on rear support as far as possible, and two parallel posts lean on front support as far as possible,
The supporting intensity for improving bracket increases bracket front end to the supporting power of top plate.
4, as shown in figure 5, front and back top beam uses the form of hinge strip balance jack, when sinciput beam stress is excessive, by putting down
The jack that weighs is balanced and is adjusted, and be will not influence the stabilization of support body, can be remained the stability of bracket.
5, there are two parallel posts supporting points for front column, increase top beam and receive force balance area range, improve the steady of bracket
It is qualitative.
6, as shown in fig. 6, revolution top beam and preceding top beam are hinged, certain angle can be swung up and down, guarantees branch bridge joint top
Supporting；It is essential to guarantee bracket protection safety by top beam before bracket and revolution top beam cabinet limit to turn round swinging under top beam；It is most
Revolution top beam tip support power may be increased, revolution jack takes loxosis in beam body to install, improves revolving support torque.
7, as shown in fig. 7, revolution front-axle beam and revolution top beam are hinged, revolution front-axle beam can swing up and down certain angle, the bottom
Angle is by revolution front-axle beam jack length limit.
8, tunnel face end support is by single upright supports, set cap relative narrower, and several framves are side by side in roadway workface
Supporting arrangement, that is, ensure that bracket avoids roadway bolt anchor cable to the adaptability of roof timbering, and using gap between frame, reduce
Damage to roofbolt anchor cable.
Alternative solution:
