Description
Technical field
Hydraulic pressure rail meter of the present invention, the rail meter that belongs to underworkings traction, transportation device designs and manufacture technology field.
Background technology
Along with the continuous development of colliery large-scale synthesis mechanical coal mining and the quick propelling of coal-face, heavy wares (mobile substation, hydraulic power unit, spraying station, emulsion water tank, cable, lubricating grease, central station of floating dock and all kinds of flame-proof switch) and auxiliary material that the down-hole is a large amount of, often need be along with the continuous propelling of driving surface, mobile or delivery in time.What at present, used in most of colliery is drawing hoist (being winch) distant range traction equipment train walking (placement location and move mode are seen Fig. 1).The safety of this mode of traction is relatively poor.Major defect has four: the one, and director and operator's apart from each other, by propagandaing directed to communicate operation, the operator can't see field condition, and it is slow to handle emergent matters; The 2nd, when running into floor uneven (hump), the steel rope summit that fastens influences traction effect; The 3rd, when running into the descending highway section, can slip the car phenomenon; The 4th, speed is very fast, and safety is relatively poor.
The patent No. of my company application is our first generation product of record in the utility model patent of ZL201020112053.X, both remedy cable work and can not adapt to the defective of turning and transporting, overcome the down-hole again and invested motor-driven monorail hoist, rope traction monorail hoist, motor-driven road railer, rope traction road railer, motor-driven rack locomotive, assistant conveyance such as motor-driven trackless rubber tire locomotive traction facility expense is many, the drawback that quantities is big, but in use we find that the shortcoming of first generation product is that the fulcrum of the claw rotating shaft of rail meter has been placed on plane on the track, when card rail jack is exerted pressure greatly, whole locomotive body is lifted, braking force is subjected to the restriction of car body deadweight and is difficult for improving, existing potential safety hazard can not satisfy some large-scale colliery clients' needs.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides the hydraulic pressure rail meter that a kind of braking force is not subjected to car body deadweight constraint, braking force is big, and is safe and reliable.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the hydraulic pressure rail meter, comprise: card rail jack, connecting rod, master jaw, claw and casing, casing top is provided with card rail jack, the bottom of card rail jack and an end of two connecting rods are hinged, two connecting rod symmetries are installed in the both sides of card rail jack, the other end of two connecting rods respectively with the upper articulation of a master jaw, claw is fixedly arranged at the bottom of two master jaws, two master jaws connect by connecting panel, described casing top has chute, and bearing pin is installed on the master jaw, and pin sleeve is contained in the chute.
Inboard, two master jaw middle parts fixedly has pillar stiffener respectively, and two master jaws connect by two pillar stiffener contacts.
Described pillar stiffener is the hemicycle cylindricality.
The present invention compares the beneficial effect that has with prior art:
The present invention moves to the fulcrum of the claw rotating shaft of rail meter on the casing of rail meter by plane on the original track, allow rail meter by the internal force transmission, the power of stepping up of rail meter jaw is changed, broken away from the influence of car body deadweight, thereby significantly improved braking force, the gripping power of each rail meter can reach 667KN, the about 100KN of braking force, the bicycle braking force, namely the braking force of main car or secondary car can reach 400KN;

The specific embodiment
As shown in Figure 1, the hydraulic pressure rail meter, comprise: card rail jack 1, connecting rod 2, master jaw 3, claw 4 and casing 5, casing 5 tops are provided with card rail jack 1, the bottom of card rail jack 1 and an end of two connecting rods 2 are hinged, two connecting rod 2 symmetries are installed in the both sides of card rail jack 1, the other end of two connecting rods 2 respectively with the upper articulation of a master jaw 3, claw 4 is fixedly arranged at the bottom of two master jaws 3, two master jaws 3 connect by connecting panel 2, have chute 6 on the described casing 5, bearing pin 7 is installed on the master jaw 3, bearing pin 7 is sleeved in the chute 6.Inboard, two master jaw 3 middle parts fixedly has 8, two master jaws of pillar stiffener 3 to connect by 8 contacts of two pillar stiffeners respectively.Described pillar stiffener 8 is the hemicycle cylindricality.
The present invention moves to the fulcrum of the claw rotating shaft of rail meter on the casing of claw case by plane on the original track, allows rail meter by the internal force transmission, and the power of stepping up of rail meter jaw is changed, and has broken away from the influence of car body deadweight, thereby has significantly improved braking force.
Shown in Fig. 2-4, initial, descending for hydraulic pressure rail meter of the present invention, the position view during braking blocks rail jack 1 to the high-pressure emulsion injection that hydraulic power unit transports earlier, and at this moment, the claw 4 of rail meter just stretches out downwards, and rides on the orbit.Continue pressurization, claw 4 is just embraced two sides of track tightly.
