Abstract
An electric servo turnout switch machine for reversing turnouts of a coal mine rail transport line comprises a servo motor driver, a direct current servo motor, a gear box, a reduction gear set, an electric cylinder body, a bearing, a lead screw, a telescopic rod, a connector, a position guide rod and an upper limit switch and a lower limit switch. The utility model provides an electric servo switch machine which is convenient to install, simple in structure and high in sensitivity.
Description
Technical Field
The utility model relates to a switch machine that is used for colliery track transport line switch to commutate especially relates to an electronic servo switch machine.
Background
Production equipment, materials, coal gangue and the like of the coal mine mainly depend on transportation of a rail locomotive. In the rail transportation process, the rail transportation direction is changed, the positions of the turnouts are switched, and the turnout is completely finished by the turnout switch machine.
The traditional pneumatic turnout switch machine is installed under a roadway bottom plate, is eroded by silt and sewage for a long time, is insensitive in signal receiving and poor in control quality, is easy to damage, and has the defects that the track is not closely attached. The hydraulic turnout switch machine has serious oil leakage, low working efficiency and poor turnout sealing degree, and is very easy to cause a turnout drop accident at the turnout, thereby causing potential safety hazards.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an electric servo switch machine that simple to operate, simple structure, action are reliable, sensitivity is high.
In order to achieve the purpose, the utility model provides a pair of electric servo switch machine, including push-and-pull plate (2), position guide arm (3), last limit switch (4), lower limit switch (5), servo motor driver (6), gear box (7), reduction gear group (8), direct current servo motor (9), electronic jar cylinder body (10), bearing (11), lead screw (12), telescopic link (13), connector (14) that can control switch (1) switching-over.
The electric servo turnout switch machine is characterized in that a servo motor driver (6) controls a direct current servo motor (9) to rotate, the direct current servo motor is decelerated through a deceleration gear set (8) to drive a screw rod (12) to rotate, a nut on a telescopic rod (13) reciprocates on the screw rod (12), a connector (14) and a push-pull plate (2) are used for driving a turnout (1) to change directions, an upper limit switch (4) and a lower limit switch (5) give signals to the servo motor driver (6) after the turnout is in place, and the direct current servo motor (9) stops acting.
According to the gear box (7) and the electric cylinder body (10) of the switch machine, the material is forged aluminum alloy and is subjected to smoothing treatment.
The telescopic rod (13) of the point switch is characterized in that the material is high-strength aluminum alloy and is corrosion-resistant.
The utility model has the advantages that: the servo motor is integrated with the point switch, the installation is convenient, the structure is simple, the sensitivity is high, the interference of sewage and sludge is avoided, the service life is long, no fault exists in severe environment, and the protection grade can reach IP 66. Long-term working, high-strength and high-precision positioning, stable movement and low noise. The pneumatic and hydraulic point switch machine only needs to be regularly greased and lubricated in the complex environment, does not have wearing parts to be maintained and replaced, solves the problems of poor sealing performance and easy action error after the pneumatic and hydraulic point switch machine is worn for a period of time, and reduces the downtime and overhaul time caused by the need of replacing the wearing parts. The direct-current servo motor can be connected with an underground network, and remote control and intelligent control are effectively realized.
Drawings
Fig. 1 is the structure schematic diagram of the electric servo switch machine of the utility model.
Fig. 2 is a schematic diagram of an internal structure of the electric servo turnout switch.
Detailed Description
The structure and the working principle of the electric servo switch machine of the present invention will be further described in detail with reference to the accompanying drawings.
In the figure, a servo motor driver (6) is connected with a direct current servo motor (9) through a cable, the direct current servo motor (9) and an electric cylinder body (10) are fixed on one side of a gear box (7), a motor reduction gear set (8) is meshed with a screw rod (12), a bearing (11) supports the screw rod (12), a connecting head (14) is fixed on the rod end of a telescopic rod (13) on the screw rod (12), a fixing pin on the connecting head (14) is connected with a push-pull plate (2), and the push-pull plate (2) is fixed with a turnout (1). The position guide rod (3) is fixed at the rod end of the telescopic rod (13), and the upper limit switch (4) and the lower limit switch (5) are fixed on the electric cylinder body (10).
The utility model discloses a direct current servo motor drives the lead screw rotation, changes into linear motion through the telescopic link, promotes the push-and-pull board and drives switch conversion locomotive advancing direction.
Claims (1)
1. The utility model provides an electronic servo switch goat, characterized by servo motor driver, direct current servo motor, the gear box, reduction gear group, electronic jar cylinder body, a bearing, the lead screw, the telescopic link, the connector, the position guide arm, upper and lower limit switch constitutes, servo motor driver control direct current servo motor rotates, through reduction gear group speed reduction, drive the lead screw rotatory, the telescopic link passes through connector and push-and-pull plate drive switch conversion direction, last limit switch, lower limit switch give servo motor driver signal after target in place, direct current servo motor stops the action.
