Description

A kind of prevent-moving car inhibiting device

Technical field

The present invention relates to coal transport equipment, be related specifically to a kind of prevent-moving car inhibiting device.

Background technology

Underground coal mine production and transport is Frequent Accidents link, wherein larger with derailing accident generation harm, once generation sport car, the loss caused is inestimable, not only damage mine car and equipment, the life security of impact production and people again, at present, the actual requirement of the catcher distance transportation safety of mine also has a segment distance, particularly in digging tunnel, most tunnel is acclive, all generally install two rail meters to be in orbit used for spacing and prevent-moving car in tunnel, but existing rail meter volume is smaller, rail meter and rail contact area little, rail meter and interorbital friction force less, and the vehicle contact area on rail meter and track is also less, this makes rail meter can stop quantity and the limited mass of vehicle, be unable to bear the impact that vehicle is larger, and prevent-moving car process easily makes road under vehicle, therefore existing this rail meter because of reliability poor, safety performance is low, the defects such as prevent-moving car effect is undesirable, to Safety of Coal Mine Production, there is larger hidden danger, a kind of prevent-moving car inhibiting device of new design for this reason, improve prevent-moving car performance, improve mine roadway transportation safety coefficient, guarantee the effective measure of Mine haul safety.

Summary of the invention

The object of the invention is for existing deficiency, a kind of prevent-moving car inhibiting device provided, sound construction, can effectively stop that vehicle, in tunnel, sport car occurs.

Technical scheme of the present invention is achieved in that a kind of prevent-moving car inhibiting device, mainly comprise column, square groove, upper engaging lug, lower engaging lug, strut, bearing pin, clamping plate, rail, bolt, sleeper, column length is 1000 ~ 2000mm, column lower end has square groove, column top the right and left welds engaging lug respectively, column lower end the right and left welds second line of a couplet lug respectively, upright post vertical stands on rail, rail is through column square groove, clamping plate pass through Bolt Connection through rail bottom side and the lower engaging lug erectting column, upper engaging lug on strut one end and column passes through hinge, other end diagonal brace at the bottom of lane on, on sleeper, a root post respectively erect by two rail in left and right.

A kind of prevent-moving car inhibiting device provided by the invention, two one steel rails are laid on the sleeper in tunnel, a conveying track is formed in tunnel, a root post respectively erect by two, left and right on sleeper rail, rail is through the square groove on column, and bearing force is formed to vertical column, clamping plate pass through Bolt Connection through the bottom side of rail with the lower engaging lug erectting column, column is fixedly erected on rail, hinge is passed through with the upper engaging lug erect on column in one end of strut, other end diagonal brace at the bottom of lane on, column carries out diagonal ligament, utilize the structure of triangle stability, greatly strengthen the steadiness of column, improve column to be hit ability, column length is 1000 ~ 2000mm, be made into the height a little more than the vehicle that orbits, to increase area when column and vehicle contact, area is blocked when this has increased substantially vehicle generation sport car, be conducive to stopping vehicle generation sport car and road under control vehicle, in tunnel, when there is sport car in orbit in vehicle, the column that vehicle and rail are erect collides, column is under the effect of strut, sustain the impact that sport car vehicle occurs, keep erectting attitude not change, block vehicle to continue to move forward, avoid serious derailing accident occurs.

The invention has the beneficial effects as follows: a kind of prevent-moving car inhibiting device provided, structure is simple, mobile to be arranged conveniently, and prevent-moving car performance safety is reliable, effectively prevent the life and property loss caused when there is sport car, improves the working environment of coal miner.
