Abstract
The utility model discloses an emergency stop brake apparatus of an electric carry scraper. The emergency stop brake apparatus comprises a mounting seat and an upright plate. The mounting seat is used for being mounted in a cab of the electric carry scraper, a brake switch is mounted on the mounting seat and is provided with a brake handle, the upright plate is mounted on the mounting seat and is positioned behind the brake switch, an electromagnet is mounted on the front wall surface of the upright plate, a wire of the electromagnet is connected with a storage battery of the electric carry scraper by a power switch, and the electromagnet is further connected with the brake handle by a stay; an adjusting screw which is positioned in front of the brake switch is further mounted on the mounting seat, and a spring is connected with the brake handle and the adjusting screw. The emergency stop brake apparatus has the advantages that an emergency stop switch is controlled by the electromagnet when in a working state, a brake pad can quickly act under the effect of the spring in case of power failure, accordingly, slipping of a vehicle can be timely and effectively controlled, slipping accidents of the carry scraper on slope ramps can be prevented, and the safety of operators can be effectively protected.
Description
technical field
The utility model relates to a kind of brake equipment, specifically the anxious dead-man's device that stops of a kind of electric LHD.
background technology
Metal/and stage casing, deep, non-metal mine down-hole ramp adopt electric LHD transport more.In the operational process of electric LHD on ramp, due to the not anxious dead-man's device that stops, run into and have a power failure while waiting burst emergency stop, operative employee often has little time reaction, pull operation handle in time, very easily cause scoper at ramp upper pulley, thereby the Peril Incidents such as device damage and personal casualty occur.
Utility model content
Technical problem to be solved in the utility model is, by providing a kind of electric LHD the anxious dead-man's device that stops,
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
Electric LHD is anxious stops dead-man's device, comprises for being arranged on the mount pad in electric LHD driving compartment, mount pad
On brake switch is installed, described brake switch is with brake-applying handle, it is characterized in that: also comprise the riser that is arranged on mount pad and is positioned at brake switch rear, and on the front face of described riser, electromagnet is installed, the wire of this electromagnet is connected with the storage battery of electric LHD by source switch, and this electromagnet is also connected with described brake-applying handle by stay cord; The adjustment screw that is positioned at brake switch front is also installed on mount pad, and is connected with spring between described brake-applying handle and adjustment screw.
Good effect of the present utility model is: in the time that emergency stop switch is in running order; by magnet control; can utilize the effect of spring that brake facing is moved rapidly once have a power failure; control timely and effectively vehicle slip-down; avoid scoper that coaster accident occurs on ramp, effectively protect the safety of operating personal.Brake when this device can be realized electric LHD chance emergency stop is completely controlled automatically, greatly improves than common electric scoper emergency stop switch safety performance, and the electric LHD using under similarity condition is had to good promotion prospect.
brief description of the drawings
Fig. 1 is structure of the present utility model and principle of work schematic diagram.
detailed description of the invention
Further illustrate the utility model below in conjunction with drawings and Examples.
As Fig. 1, the utility model comprises for being arranged on the mount pad 1 in electric LHD driving compartment, and brake switch 3 is installed on mount pad 1, and described brake switch 3 is with brake-applying handle 5.While pulling back brake-applying handle 5 to control position, brake facing in brake switch 3 departs from brake drum, and electric LHD is in running state, when promoting forward brake-applying handle 5 to anxious off-position and putting, brake facing locking brake drum in brake switch 3, electric LHD is in dead ship condition.
The adjustment screw 7 that is positioned at brake switch 3 fronts is installed on mount pad 1, and is connected with spring 6 between described brake-applying handle 5 and adjustment screw 7.By adjusting the usable length that screw 7 can regulating spring 6, and then regulate its screen resilience.
The utility model also comprises the riser 2 that is arranged on mount pad 1 and is positioned at brake switch 3 rears, and electromagnet 4 is installed on the front face of described riser 2, and the wire of this electromagnet 4 is connected with the storage battery of electric LHD by source switch.This electromagnet 4 is also connected with described brake-applying handle 5 by stay cord.
When electric LHD has a power failure suddenly, electromagnet 4 dead electricity simultaneously, spring 6 relies on screen resilience to promote forward brake-applying handle 5 and puts to anxious off-position, the brake facing locking brake drum in brake switch 3, electric LHD is automatically in dead ship condition.
