Abstract

The utility model relates to a rail vehicle obstructing and position-limiting device. Two obstructing claws are in L shapes, and are arranged below a track with a define distance, wherein one end of each of the obstructing claws are hinged on a support seat through pin shafts; the rear end of the support seat are fixed with a plurality of spring shafts in the horizontal direction; the spring shafts penetrate through hole sleeves on track support beams which are positioned below the track and in the direction perpendicular to the track; the rear ends of the spring shafts are sheathed with compression springs which are compressed among the track support beams and fix sheets fixed at tail ends of the spring shafts; the bottom parts of two track support beams are fixed with lower frames which are hinged with swing links; the upper ends of the swing links are provided with rollers positioned below the obstructing claws; driving cylinders are hinged among ear seats fixed on the lower frames and the lower ends of the swing links. The rail vehicle obstructing and position-limiting device has the advantages of compact constructional dimension, easy maintenance and repair, strong shock resistance, wide suitable tonnage range of mine vehicles, reliable vehicle obstructing, simple laying process and little space occupation.

Description

The guideway vehicle inhibiting device of holding up traffic

Technical field:

The utility model relates to a kind of inhibiting device that is used for the vehicle of motion on the narrow gauge conveying track stopped at the fixed location of a certain requirement.Specialized equipments such as it and car puller, cage chair, cage are worked in coordination, and make the mine transportation facilities reach the purpose of behaviour's car mechanization of operation and automation.

Background technology:

Existing narrow gauge transports employed guideway vehicle inhibiting device has resistance to take turns, the various types such as grade of barrier plate, its mechanism that holds up traffic holds up traffic to take turns when leaning on track outside resistance claw to close to hold up traffic, there is following shortcoming in they: when resistance claw is opened and the gap of wheel is limited, the vehicle of passing through is restricted, flat truck etc. be difficult to by; To the bigger mine car of bigger mine car of tonnage or the wheel footpath shakiness of holding up traffic, impact resistance is relatively poor; Transmission device and shock absorber are arranged in both sides, occupy than large space, and width between centers was restricted when the parking lot two pass was arranged.

Summary of the invention:

The purpose of this utility model provides a kind of guideway vehicle inhibiting device of holding up traffic, and the vehicle adaptive capacity is strong to holding up traffic, and impact resistance is big, and the mine car tonnage scope that is suitable for is wide, and it is reliable to hold up traffic, and does not take sheaf space.

The purpose of this utility model realizes as follows: the guideway vehicle inhibiting device of holding up traffic also relates to resistance claw, two resistance claws are the L type, the track below that is arranged on separated by a distance, the one end is hinged on the bearing by bearing pin, resistance claw can swing up and down, at the fixing some spring shafts of a base rear end along continuous straight runs, spring shaft passes under the track borehole jack with the rail supported beam of track vertical direction, and can in borehole jack, move forward and backward, the spring shaft rear end is with compression spring, spring is compressed in the rail supported beam and is fixed between the fixed plate of spring shaft tail end, by spring shaft, spring, fixed plate constitutes shock absorber, shock absorber can move with resistance claw and bearing thereof, absorbs the suffered impact of holding up traffic by length of spring compressed.In two rail supported beams bottom fixed frame, hinged fork on underframe, the upper end of fork are equipped with roller and are in below the resistance claw, hinged driving cylinder between the lower end that is fixed on ear seat on the underframe and fork, the ear seat of oil cylinder afterbody and underframe is hinged, and piston rod end and fork are hinged.The roller of fork upper end has reduced friction force, the rotation by fork can be like a cork with resistance claw jack-up or fall, mine car is hindered spacing or is let pass.The withdrawal of driving cylinder piston rod drives fork when holding up traffic, and fork roller end is lifted, and the jack-up resistance claw hooks axletree or baffle plate, thereby makes the mine car location; The driving cylinder piston rod stretches out, and connecting rod roller end is resetted, and resistance claw falls by deadweight, and mine car can pass through.

The utility model can be combined into the compound inhibiting device of holding up traffic by two covers, and two pairs of resistance claw actions of the compound inhibiting device of holding up traffic are opposite, and during wherein a pair of lifting, another is to falling, and the resistance claw interlock realizes by the driving cylinder loop.Spacing between the two pairs of resistance claws can according to the quantity of spacing mine car and the length of mine car determine again.The compound inhibiting device of holding up traffic is mainly used in that train is decomposed or the occasion of the two cars of bicycle.

This guideway vehicle inhibiting device scantling of structure compactness of holding up traffic, maintenance and repair easily; Impact resistance is big, and the mine car tonnage scope that is suitable for is wide, and it is reliable to hold up traffic; Technology arrangement is simple, and it is little to take up room.

Description of drawings:

Fig. 1 is the hold up traffic front view of inhibiting device of the utility model guideway vehicle.

Fig. 2 is the hold up traffic birds-eye view of inhibiting device of the utility model guideway vehicle.

The specific embodiment:

With reference to Fig. 1, Fig. 2, track 8 is the track of mine car 9 operations, rail supported beam 7 is in below the track 8, two resistance claws 6 that are provided with separated by a distance below track 8, they are the L type, the one end is hinged on the bearing 2 by bearing pin, at bearing 2 rear end along continuous straight runs fixing spring axles 1, spring shaft 1 passes under the track borehole jack with the rail supported beam 7 of track vertical direction, spring shaft 1 rear end is with compression spring, spring is compressed in rail supported beam 7 and is fixed between the fixed plate of spring shaft 1 tail end, by spring shaft 1, spring, the shock absorber that fixed plate constitutes is the 2-4 group, in two rail supported beams, 7 bottom fixed frame 4, hinged fork 5 on underframe 4, the upper end of fork 5 is equipped with roller and is in below the resistance claw, hinged driving cylinder 3 between the lower end that is fixed on ear seat on the underframe 4 and fork 5, and driving cylinder 3 can be with oil cylinder or cylinder.Action by controlling and driving cylinder 3 can drive resistance claw 6 and rise or fall, and realizes holding up traffic or the purpose of open to traffic.
