Abstract
A parallel driving device of an electric traction rail clamping rack rail locomotive belongs to supporting facilities of a rail transportation system of an underground coal mine, and comprises a bearing platform, four bearing trolleys, a driving speed reducer, four explosion-proof driving motors and a driving fluted disc; the four bearing trolleys are positioned on two sides below the bearing platform and connected with the bearing platform through pin shafts, so that the bearing platform can smoothly move on a clamping rail toothed rail, the driving speed reducer and the bearing platform are fixedly connected at the central position of the bearing platform through bolts, and the four bearing trolleys are characterized in that an input shaft of the driving speed reducer and an output shaft of the driving speed reducer are arranged in parallel, the input shaft of the driving speed reducer is connected with an explosion-proof driving motor shaft, and the output shaft of the driving speed reducer is connected with a driving fluted disc. The utility model adopts the motor driving efficiency high, the efficiency can reach 90 percent, and the production cost is low; the whole machine is simple in structure and low in maintenance cost in an electric traction driving mode.
Description
Technical Field
The utility model discloses mainly be applied to in the colliery underground railway track transport system, in the track transport system, mainly adopt to use the mechanical tubes rail to be the orbit system of card rail mode and use roller rack transmission as the transport locomotive of drive mode.
Background
In the aspect of coal mine auxiliary transportation, rail transportation is more and more emphasized, wherein a rail clamping rail system developed on the basis of a ground rail is widely used in China.
The ground rail clamping rail system is divided into a rope traction clamping rail system and an automatic power clamping rail system according to different traction modes.
The rope traction rail clamping track system mainly adopts a vertical groove as a running track and adopts a traction mode that a group of endless ropes are connected with a power turntable and an endless rope tractor. This system presents a system problem: 1. limited by the length of the endless rope, the general transportation length is within 2000 meters; 2. the steel wire rope is adopted for traction, so that the risk of rope breakage exists, and the potential safety hazard is high; 3. the endless rope can only be transported once at a time, cannot realize multi-vehicle continuous transportation, and has limited transportation capacity.
The automatic power rail clamping track system is mainly used in a transportation mode that a rail clamping rack track is used as a transportation track, the track is a special-shaped track, a vertical rack is arranged in the middle of the track, and the locomotive is driven to move forward and backward by the continuous rotation of a middle driving gear of the locomotive.
At present, the rail clamping rack rail locomotive mainly uses an explosion-proof diesel engine as a power source, and a hydraulic motor is driven by a hydraulic system to drive the locomotive to move forward and backward.
The hydraulic motors are arranged on the driving devices, the four hydraulic motors on one driving device are respectively arranged on two sides of the driving device, and the speed reducer drives the middle driving fluted disc to realize the forward and backward movement of the driving device.
Disclosure of Invention
The utility model discloses mainly solve following problem: 1. the hydraulic motor is a low-speed large-torque motor, so that the cost is high; 2. the hydraulic motor has low driving efficiency and high energy consumption.
The technical scheme of the utility model: a parallel driving device of an electric traction clamping rail rack rail locomotive comprises a bearing platform, four bearing trolleys, a driving speed reducer, four explosion-proof driving motors and a driving fluted disc; the four bearing trolleys are positioned on two sides below the bearing platform and connected with the bearing platform through pin shafts, so that the bearing platform can smoothly move on a clamping rail toothed rail, the driving speed reducer and the bearing platform are fixedly connected at the central position of the bearing platform through bolts, and the four bearing trolleys are characterized in that an input shaft of the driving speed reducer and an output shaft of the driving speed reducer are arranged in parallel, the input shaft of the driving speed reducer is connected with an explosion-proof driving motor shaft, and the output shaft of the driving speed reducer is connected with a driving fluted disc.
When the explosion-proof driving motor works, the explosion-proof driving motor drives the driving fluted disc to rotate after passing through the speed reducer, and the driving fluted disc is meshed with the rack in the middle of the clamping rail and the rack rail to drive the whole driving device to move forwards and backwards.
The utility model adopts the motor driving efficiency high, the efficiency can reach 90 percent, and the production cost is low; the whole machine is simple in structure and low in maintenance cost in an electric traction driving mode.
