Abstract
The utility model relates to movable protective roof boarding of a well bore. The roof boarding which can swing around a shaft is fixed to a shaft seat through a pin shaft. The shaft seat is fixed to a support frame. A connecting rod mechanism composed of two hinged connecting rods is arranged between the roof boarding and the support frame. One end of the connecting rod mechanism is hinged with the roofing board, and the other end is hinged with the support frame. A spacing block which limits the swinging angles of the connecting rods is fixed to the roofing board. A driving cylinder is connected between the support frame and the connecting rod mechanism. One end of the driving cylinder is hinged with an ear seat of the support frame, and the other end is hinged with the hinged point of the two connecting rods of the connecting rod mechanism. The movable protective roof boarding of a well bore is suitable for vertical well lifting of a lifting container guided by a wire rope, ensuring a safe gap. The utility model has the advantages of convenient operation, no need of manpower to push away, compact, simple and reliable structure, little space occupation and short roadway of an ingate.
Description
Technical field:
The utility model relates to the movable protection of a kind of pit shaft roof boarding, the mine that is used for the vertical cage hoisting, when hoisting container is in each level of down-hole and stops, the safety that this roof boarding stretches out the turnover personnel plays protective action, especially is fit to flexible cage guide and requires the bigger mine in safe operation gap as what hoisting container promoted guiding.
Background technology:
The roof boarding that the mine of existing vertical cage hoisting has rigid cage guide to be provided with is stiff, also needs to leave certain safe distance apart from cage; The roof boarding of existing rope hoisting setting need leave bigger safe operation gap.There is following shortcoming in they: need manually push certain distance open when (1) inconvenient operation, following long material; (2) take up room greatlyyer, the ingate tunnel is long; (3) the flexible cage guide roof boarding is retained apart from bigger, drips to drench easily on one's body the personnel of turnover cage, and foreign material also damage personnel easily.
Summary of the invention:
The purpose of this utility model provides the movable protection of a kind of pit shaft roof boarding, be in full state at ordinary times, lift when cage is parked in this horizontal parking lot and prevent that trickle and dropped object from damaging the personnel that pass in and out cage, it is capable of expansion and contraction, easy to operate, it is little to take up room.
The purpose of this utility model realizes as follows: roof boarding is formed by steel structure support and steel plate assembly welding, roof boarding is fixed on the axle bed by bearing pin and can swings around axle, axle bed is fixed on the support, the linkage that device is made of the hinged connecting rod of two joints between roof boarding and support, one end of linkage is hinged on the roof boarding, and the other end is hinged on the support; Be connected driving cylinder between support and linkage, driving cylinder is hydraulic cylinder, cylinder or electric pushrod.Driving cylinder one end is hinged on the ear seat of support, and its other end is hinged on the middle part of linkage.
On roof boarding, be fixed with the limited block of limiting rod pendulum angle, when roof boarding is backed down, lean against with the hinged connecting rod of roof boarding and to be limited to continue swing on the limited block.
The articulated position of driving cylinder and linkage is on the hinge point of two connecting rods.Can certainly be hinged on the pin joint place of any one connecting rod near them.
In normal lifting process, piston rod is in retracted position, roof boarding falls, and two connecting rods are in the ∨ font, when cage when this level is stopped jar, piston rod stretches out, make roof boarding be in the state of lifting by connecting rod, at this moment two connecting rod mid points are by being wired to the state of ∧ type, because the effect of limited block, at this moment piston rod does not bear the gravity of roof boarding, and entire mechanism is in stable self-locking state.
The movable protection of this pit shaft roof boarding is fit to the vertical shaft hoisting of wire rope guiding hoisting container, guarantees the safe clearance; Easy to operate, do not need manpower to push open; Compact conformation, it is little to take up room, and the ingate tunnel is short; Simple and reliable for structure.
Description of drawings:
Fig. 1 is the front view of the movable protection of the utility model pit shaft roof boarding.
Fig. 2 is the vertical view of the movable protection of the utility model pit shaft roof boarding.
The specific embodiment:
With reference to Fig. 1, Fig. 2, it comprises that roof boarding 3, bearing pin 1, linkage 4, driving cylinder 5, ear seat 6, limited block 2, support 7 and axle bed 8 constitute.Can be fixed on the axle bed 8 by bearing pin 1 around the roof boarding 3 of axle swing, axle bed 8 is fixed on the support 7, support 7 is fixed with the supporting frame in the pit shaft, the linkage 4 that device is made of the hinged connecting rod of two joints between roof boarding 3 and support 7, one end of linkage 4 is hinged on the roof boarding 3, and the other end is hinged on the support 7; On roof boarding 3, be fixed with the limited block 2 of that hinged connecting rod swing angle of restriction and roof boarding; Be connected driving cylinder 5 between support 7 and linkage 4, driving cylinder 5 one ends are hinged on the ear seat 6 of support 7, and its other end is hinged on the hinge point of 4 liang of connecting rods of linkage.The motion of the flexible drive linkage 4 by driving cylinder 5 piston rods realizes strutting and regaining of roof boarding 3, when strutting, and two connecting rods of linkage 4 and limited block 2 formation self-locking mechanisms, roof boarding 3 unlikely decompressions because of driving cylinder 5 fall.
