Technical Field

The invention relates to a high-efficiency turning structure of an electric locomotive.

Background

The electric locomotive as one kind of track vehicle hauling equipment has the power of driving wheel with the hauling motor and running the locomotive on the track with the friction force between the wheel and the track surface. At present, the running direction of a mine car needs to be changed in mine transportation, except for turnouts, the mine car needs to turn around a curve, and therefore the occupied area is large.

The 'man' shaped turnout widely used in the underground coal mine can only realize that the electric locomotive moves from one end of the train to the other end, but can not realize 180-degree turning around of the electric locomotive. The driver cab of the electric locomotive is positioned at the head of the electric locomotive, and when the tail of the electric locomotive pulls a train to run in a roadway, the driver positioned in the driver cab can clearly see whether pedestrians or other sundries exist on the roadway in front, so that corresponding treatment measures are taken. After the train is pulled to a destination, the electric locomotive passes through the herringbone turnout and is driven to the tail of the train from a track beside the train, the locomotive of the electric locomotive is pulled to return the train, in the process, the electric locomotive does not complete 180-degree turning around, so when the train returns, the locomotive of the electric locomotive connected with the train is driven, when the driver drives the electric locomotive to return, about 3 meters in front is the body part of the electric locomotive, and in addition, a storage battery stored on the electric locomotive leads to unclear sight of the driver, so that accidents are easy to occur.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides an efficient electric locomotive turning structure which is used for changing the direction of an electric locomotive in a mine car circulating system and is beneficial to realizing mechanized transportation at the well bottom.

The technical scheme adopted by the invention is as follows:

the utility model provides an efficient electric locomotive structure of turning around, includes carousel and driving system fixed track (1) on the carousel, the carousel includes base (2), lower base (3) and carousel bearing (4), and lower base (3) are fixed on the concrete foundation with rag bolt (5), and the inboard and lower base (3) of carousel bearing (4) are fixed mutually, and the outside movable part and last base (2) of carousel bearing (4) are fixed mutually, the outside movable part or last base (2) circumference of carousel bearing (4) are equipped with the driving tooth, driving system's output drive gear (8) with the driving tooth meshing transmission is connected.

Efficient electric locomotive structure of turning round, be fixed with rail frame (6) at last base (2) up end, terminal surface and last base (2) fixed connection under rail frame (6), fixed rail (1) of rail frame (6) up end.

Efficient electric locomotive turn-around structure, driving system adopt hydraulic power system, hydraulic power system includes hydraulic power unit, takes hydraulic motor (7) of stopper, hydraulic motor (7) are fixed on base (3) down with the bolt, hydraulic motor output shaft end installation output drive gear (8).

Efficient electric locomotive structure of turning round, with the carousel cooperation is equipped with stop device and electrical system, electrical system includes PLC controller, infrared ray sensor, position sensor, remote controller, and infrared ray sensor installs on the tunnel edge, and position sensor installs on the carousel, infrared ray sensor and position sensor output signal connection PLC controller, PLC controller control connection hydraulic power system.

When the hydraulic pump station provides high-pressure oil for the hydraulic motor, the transmission pinion arranged on the hydraulic motor drives the turntable bearing of the large gear to start rotating, so that the head of the motor parked on the turntable can be turned by 180 degrees.

The invention has the beneficial effects that:

the high-efficiency turning structure of the electric locomotive utilizes the stable and reliable low-speed turntable to enable the electric locomotive to automatically change the direction in a large range, and the curvature radius can be very small (the diameter of the machine disc is only 2 meters). The mine car reversing device has the characteristics of small occupied area, high efficiency and stable and reliable mine car reversing, and is suitable for changing the running direction of ground yards and shaft bottom yards with limited sites.
