Description
Technical field
The utility model relates to the accessory appliances in tunnel, is specially a kind of lineoutofservice signal pull steering hardware.
Background technology
In coal mine down-hole tunnel, utilizing steel rope to pull dolly to advance in orbit is modal transportation mode, but tunnel meander often, when steel rope is turned, current employing simple fixed support part, and the good supporter of neither one, make steel rope abrasion serious, loss is large, and additionally can consume pulling force, even produce serious safety misadventure.
Summary of the invention
The purpose of this utility model is to provide a kind of lineoutofservice signal pull steering hardware be exclusively used in coal mine down-hole tunnel.
The utility model adopts following technical scheme to realize:
A kind of lineoutofservice signal pull steering hardware, comprise pedestal, the root both sides of described pedestal are connected to hydraulic actuating cylinder, the cylinder ends of described hydraulic actuating cylinder and the root of pedestal hinged, the piston rod end of described hydraulic actuating cylinder is fixed with pulley; Described pedestal is between two block plates, and the root namely around pedestal in two hydraulic actuating cylinders gap between two block plates rotates; Described steel plate has along the rotational trajectory of two hydraulic actuating cylinders the knock hole that two row are camber line arrangement, the cylinder body of described hydraulic actuating cylinder is provided with locating dowel pin axis hole, realizes location when hydraulic actuating cylinder rotates corresponding knock hole on the locating dowel pin axis hole and steel plate being inserted the cylinder body of hydraulic actuating cylinder to a certain angle by locating dowel pin.
During work, lineoutofservice signal pull steering hardware level is fixedly mounted on the turning in tunnel, the anglec of rotation of two hydraulic actuating cylinders is adjusted according to turning radius, as shown in Figure 1, the each spinning of hydraulic actuating cylinder on left side and right side, utilize in knock hole corresponding on the locating dowel pin axis hole of locating dowel pin insertion hydraulic cylinder body and steel plate, realize location; Then the piston rod in hydraulic actuating cylinder stretches out, and makes steel rope just in time be positioned at the race of two pulleys.Finally, the dolly that engine installation just can pull steel rope to drag on track advances.When moving of car is to turning, now, steel rope has almost all been turned, then the piston rod in retraction hydraulic actuating cylinder, extracts bearing pin simultaneously, rotates into horizontal, allow dolly pass through turning smoothly by two hydraulic actuating cylinders.
Compared with prior art, advantage is as follows:
1, provide a good kinematic support effect at turning to steel rope, auxiliary steel wire rope turns to smoothly, after steel rope turns to, can be regained by oil cylinder.
2, due to the adjustable effect of rotational angle of two support cylinders, this device is made can to adapt to the bend of different turn radius, widely applicable.
3, the preparation of this device is simple, easy to maintenance, long service life.
The utility model is reasonable in design, solves the problem that in existing tunnel, steel rope turns to smoothly, and does not affect advancing of dolly on track.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-pedestal, 2-hydraulic actuating cylinder, 3-pulley, 4-steel plate, 5-knock hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described in detail.
A kind of lineoutofservice signal pull steering hardware, as shown in Figure 1, comprise pedestal 1, the root both sides of described pedestal 1 are connected to hydraulic actuating cylinder 2, the cylinder ends of described hydraulic actuating cylinder 2 and the root of pedestal 1 hinged, the piston rod end of described hydraulic actuating cylinder 2 is fixed with pulley 3; Steel rope is positioned at the race of two pulleys 3, realizes turning to.
Described pedestal 1 is between two blocks of symmetrical steel plates 4 installed, and the edge of steel plate 4 is also in arcuation, and upper and lower two block plates and pedestal can adopt and be welded together, and the root namely around pedestal 1 in two hydraulic actuating cylinders 2 gap between two block plates 4 rotates; Described steel plate 4 has along the rotational trajectory of two hydraulic actuating cylinders 2 knock hole 5 that two row are camber line arrangement, one row knock hole is positioned at the left side of upper steel plate, for the location of left side hydraulic actuating cylinder, another row knock hole is positioned at the right of lower steel plate, for the location of right side hydraulic actuating cylinder, or the both sides that two row knock holees lay respectively at same steel plate are also passable, be symmetrical about pedestal.
The cylinder body of described hydraulic actuating cylinder 2 is provided with locating dowel pin axis hole, when hydraulic actuating cylinder 2 rotates to after a certain suitable angle, is inserted corresponding knock hole 5 on the locating dowel pin axis hole of the cylinder body of hydraulic actuating cylinder 2 and steel plate 4 realize location by locating dowel pin.Like this, arbitrarily can adjust the anglec of rotation of two hydraulic actuating cylinders 2, to be applied to the bend of different turn radius in tunnel.In order to supporting steel-cable when the piston rod of hydraulic actuating cylinder stretches out, during withdrawal and when rotating two hydraulic actuating cylinders to level, dolly can pass through smoothly.
Described hydraulic actuating cylinder 2 can select double acting hydraulic cylinder.Single-action hydraulic cylinder refers to that the motion oil pressure in one of them direction realizes, and by external force such as deadweight or springs when returning, two chambeies of this oil cylinder only have one end to have oil, and the other end then contacts with air.Double acting hydraulic cylinder is exactly that two chambeies have oil, and the action of both direction all will realize by oil pressure, and during specific works, manually pump realizes hydraulic actuating cylinder action.
