Description

Railway overhauls the car emergency fender guard of riding instead of walk

Technical field

The utility model relates to a kind of railway and overhauls the car of riding instead of walk, and particularly a kind of railway overhauls the emergency fender guard of the car of riding instead of walk.

Background technology

Along with China's rapid economy development, trunk railway constantly extends and enlarges, need the trunk railway of railway maintenance worker inspection and maintenance more and more longer, work capacity is also increasing, railway overhauls the car of riding instead of walk and arises at the historic moment thus, the railway maintenance worker progressively brings into use the railway maintenance to ride car instead of walk as the walking-replacing tool of patrolling and examining, and so not only reduces working strength of workers and human cost, and has improved railway maintenance worker's work efficiency greatly.Car also has the following disadvantages in use but railway maintenance is ridden instead of walk: the one, and when going out car, the railway maintenance worker patrols and examines when stopping, and can occur forgetting and close the phenomenon that electric door lock just leaves tool car, if the handle of maloperation at this moment will cause vehicle launch; The 2nd, to patrol and examine when stopping going out car, the phenomenon of pull-up hand-operated brake device also can appear forgetting, car is stopped on the slope if railway maintenance this moment is ridden instead of walk, and vehicle will produce automatically and slide; Above-mentioned two kinds of hidden dangers also can cause vehicle damage and personal injury accident when serious.For this reason, many manufacturers and knowledgeable people have carried out R and D, but do not have rational product to emerge so far as yet.

Summary of the invention

Overhaul the car above shortcomings of riding instead of walk at existing railway, the purpose of this utility model provides a kind of railway simple and reasonable, safe and reliable, that the person for driving a car leaves just automatic outage of seat and brake and overhauls the car emergency fender guard of riding instead of walk.

The technical scheme that its technical matters that solves the utility model adopts, it comprises vehicle frame, wheel shaft, rail wheel, seat, seat support, braking mechanism, seat support is fixed on the vehicle frame, the front end of described seat is hinged on the seat support, bottom of frame is hinged with connecting rod, be connected with pull bar between the other end of connecting rod and the rear end of seat, vehicle frame is equipped with oil pump by permanent seat, the piston rod of oil pump is connected with connecting rod, be connected with extension spring between connecting rod and the permanent seat, breaker device is installed on the connecting rod, and oil pump is connected with braking mechanism by oil pipe.

Described breaker device comprises cut-off switch and switch extension spring, and cut-off switch is installed on the connecting rod, and the switch extension spring is connected between cut-off switch and the permanent seat.

Described oil pressure braking mechanism comprises disc brake sheet, disc brake pump, and disc brake sheet is fixed on the wheel shaft, is fixed with the disc brake fixed support on the vehicle frame, and the disc brake pump is installed on the disc brake fixed support and with disc brake sheet and matches.

After adopting said structure, the utility model compared with prior art has following advantage: the one, and the railway maintenance is ridden car instead of walk when patrolling and examining parking, the person for driving a car leaves just outage and brake automatically of seat, improved the traveling security energy greatly, harm and the loss of having avoided maloperation and vehicle slide slope to be caused; The 2nd, simple and reasonable, cost is low, and is safe and reliable.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 looks scheme drawing for a left side of the present utility model.

The specific embodiment

Illustrated in figures 1 and 2; be ride instead of walk the specific embodiments of car emergency fender guard of a kind of railway of the utility model maintenance; it comprises vehicle frame 7; wheel shaft 15; rail wheel 18; seat 1; seat support 8; braking mechanism; seat support 8 is fixed on the vehicle frame 7; the front end of described seat 1 is hinged on the seat support 8; vehicle frame 7 bottom-hinged have connecting rod 5; be connected with pull bar 2 between the rear end of the other end of connecting rod 5 and seat 1; vehicle frame 7 is equipped with oil pump 9 by permanent seat 17; the piston rod 11 of oil pump 9 is connected with connecting rod 5; be connected with extension spring 16 between connecting rod 5 and the permanent seat 17, on the connecting rod 5 breaker device be installed, oil pump 9 is connected with braking mechanism by oil pipe 10.Described breaker device comprises cut-off switch 3 and switch extension spring 4, and cut-off switch 3 is installed on the connecting rod 5, and switch extension spring 4 is connected between cut-off switch 3 and the permanent seat 17, and the switch connection lead of cut-off switch 3 is connected on the control loop of handle 6.Described oil pressure braking mechanism comprises disc brake sheet 14, disc brake pump 13, and disc brake sheet 14 is fixed on the wheel shaft 15, is fixed with disc brake fixed support 12 on the vehicle frame 7, and disc brake pump 13 is installed on the disc brake fixed support 12 and with disc brake sheet 14 and matches.

The utility model working process is as follows: when on person for driving a car's seat during seat 1, pull bar 2 promotes connecting rod 5 and moves downward, connecting rod 5 drives piston rod 11 and moves downward, hydraulic oil in the disc brake pump 13 flows into oil pump 9 by oil pipe 10, disc brake pump 13 unclamps disc brake sheet 14, and meanwhile, connecting rod 5 drives cut-off switch 3 and moves downward, cut-off switch 3 is connected handle 6 control loops under the effect of switch extension spring 4, and railway overhauls the car of riding instead of walk and is in running state.

When seat 1 is left in person for driving a car's parking, connecting rod 5 drives seat 1 under the effect of extension spring 16 and pull bar 2 upwards resets, and promotion piston rod 11 upward movements, hydraulic oil in the oil pump 9 flows into disc brake pump 13 by oil pipe 10, disc brake pump 13 is embraced disc brake sheet 14 under the effect of hydraulic oil, meanwhile, connecting rod 5 drives cut-off switch 3 and resets, cut-off switch 3 disconnects handle 6 control loops, thereby realizes the purpose of outage automatically and brake.
