Description

Technical Field

[0001] The utility model relates to the technical field of mine road equipment, in particular to an improved driver-controlled turnout control system. Background Art

[0002] When the track of a mine car needs to be changed during operation in a coal mine tunnel, the direction of the mine car needs to be changed by changing the position of the point rail on the switch through the driver-controlled switch control equipment, that is, the switch machine. During construction, due to the limited distance between the frame walls on both sides of the mine tunnel and the limited space on both sides of the mine tunnel, the switch machine installed on the surface may hinder the movement of the mine car, so the switch machine needs to be buried in the ground on one side of the switch.

[0003] In order to reduce dust inside the mine tunnel, water mist spraying is often required, which leads to a high humidity inside the mine tunnel. Therefore, the ground soil is relatively moist. In some places close to the groundwater flow channel, there is a possibility of water seepage. These moist soils or even silt directly cover the entire switch machine, which can easily cause rust on various components of the switch machine and affect the normal operation of the overall structure. Utility Model Content

[0004] The purpose of the present invention is to provide an improved driver-controlled turnout control system to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An improved driver-controlled turnout control system includes a device body, both sides and the rear surface of the device body are fixedly installed with cover locks, the front surface of the device body is fixedly installed with a push rod structure, the push rod structure includes a sleeve, the rear end opening of the sleeve is fixedly sleeved with a flange, the inner wall of the front end opening of the sleeve is fixedly installed with a support ring, the front side of the support ring is clamped with a No. 2 sealing ring, the support ring is slidably sleeved with the side wall of the push rod body, the rear end of the sleeve is fixedly clamped with the output end probe opening through the flange, and the rear end of the push rod body is fixedly connected to the output end of the cylinder.

[0008] Furthermore, a clamping edge is fixedly installed at the edge of the upper opening of the protection box, the clamping edge is clamped with the bottom side of the sealing edge strip, and the sealing edge strip is embedded in the bottom edge of the top cover.

[0009] Furthermore, the cover lock includes a lock storage sleeve, a No. 1 sealing ring is fixedly installed at the upper opening of the lock storage sleeve, the upper opening of the lock storage sleeve is slidably sleeved with the slide bar, the upper end of the slide bar is hinged with a fastener, a slider storage sleeve is fixedly installed on the outer surface of the lock storage sleeve, a screw rod is rotatably installed in the upper and lower directions inside the slider storage sleeve, and a lifting slider fixedly connected to the slide bar is screwed and sleeved on the side surface of the screw rod.

[0010] Furthermore, the sleeve is provided with a support ring, and a support foot is fixedly provided on the bottom side of one end thereof.

[0012] Furthermore, the lock storage sleeve is fixedly installed on the front and rear side edges of both side surfaces and the middle part of the rear side surface of the protection box.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The device body and the push rod structure that have been sealed by the cover lock are buried in the ground of the mine next to the turnout. The push rod body is pushed by the cylinder, and then the turnout point rail is rotated to realize the lane change. The cover provides protection for part of the outside of the push rod body and isolates the external mine soil. When the push rod body retracts into the cover, the No. 2 sealing ring pushes off the soil attached to the side wall of the push rod body, and at the same time provides a relatively closed activity environment for the piston rod of the cylinder. This can effectively prevent the piston rod and the push rod body from being in contact with the moist soil or even silt in the mine for a long time, resulting in rust on the rod surface, affecting the smoothness of the telescopic activity, effectively improving the service life of the overall structure, reducing the frequency of replacing accessories, and saving expenses.

[0015] 2. When closing the upper opening of the protective box, cover the top cover so that the groove at the bottom of the sealing edge strip is engaged with the card edge. At the same time, the nut at the upper end of the screw rod is turned to rub the lifting slider downward inside the slider storage sleeve, driving the slider and the lower half of the fastener to be retracted into the lock storage sleeve. While limiting the rotation of the fastener, the upper part of the fastener is controlled to continuously press down the edge of the top cover, compressing the sealing edge strip made of elastic material, strengthening the tightness of the connection between the top cover and the edge of the upper opening of the protective box, and encapsulating the cylinder through the relatively closed structure composed of the protective box and the top cover to cope with the underground environment of the mine tunnel.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 4 In the embodiment of the present invention, an improved driver-controlled turnout control system includes a device body 1, and cover lock buckles 2 are fixedly installed on both sides and the rear surface of the device body 1. A push rod structure 3 is fixedly installed on the front surface of the device body 1. The push rod structure 3 includes a sleeve 301, and a flange 302 is fixedly sleeved on the rear end opening of the sleeve 301. A support ring 303 is fixedly installed on the inner wall of the front end opening of the sleeve 301. A No. 2 sealing ring 304 is clamped on the front side of the support ring 303. The support ring 303 is slidably sleeved on the side wall of the push rod body 306. The rear end of the sleeve 301 is fixedly clamped with the opening of the output end probe port 110 through the flange 302, and the rear end of the push rod body 306 is fixedly connected to the output end of the cylinder 103.

[0023] Specifically, the device body 1 and the push rod structure 3 encapsulated by the cover lock 2 are buried in the underground of the mine next to the switch, and the push rod body 306 is pushed by the cylinder 103, thereby pushing the switch point rail to rotate to achieve lane change. The sleeve 301 provides protection for part of the outside of the push rod body 306, isolating the external mine soil. When the push rod body 306 retracts into the sleeve 301, the No. 2 sealing ring 304 pushes off the soil attached to the side wall of the push rod body 306, and at the same time provides a relatively closed activity environment for the piston rod of the cylinder 103, which can effectively prevent the piston rod and the push rod body 306 from being in long-term contact with the moist soil or even silt in the mine, resulting in rust on the rod surface, affecting the smoothness of the telescopic activity, effectively improving the service life of the overall structure, reducing the frequency of replacing accessories, and saving expenses.

[0024] Example 1

The upper surface of the pipe transfer piece 104 is fixedly connected to the No. 2 gas pipeline 106, and the front surface of the protective box 101 is fixedly installed with an output end probe port 110 that is slidably sleeved with the output end of the cylinder 103.

[0026] In this embodiment, the No. 2 gas pipeline 106 is externally connected to a pneumatic valve, which connects the pneumatic valve to the compressed gas supply equipment and the control structure, and the button switch on the control structure is replaced with a universal conversion switch. The universal conversion switch has a longer service life than the button switch and does not always maintain a working state.

[0027] like Figure 1 、 4 As shown, in this embodiment, the sleeve 301 is installed with a support ring 303, and a support foot 305 is fixedly installed on the bottom side of one end; the front end of the top rod body 306 is provided with a clamping end 307, and the clamping end 307 is clamped with the clamping slot 308. The clamping slot 308 is provided at the rear end of the force-bearing end block 309, and a hinge seat 310 is fixedly installed on the upper surface of the force-bearing end block 309.

[0028] In specific implementation, during installation, similar to the installation of ordinary mine turnout control structures, first, a base block is poured with cement at the bottom of the foundation pit, and then the base block is relatively fixedly connected to the cement base block through bolts and fastening screws 102 and support legs 305. Then, the soil is backfilled to bury the entire device. The load-bearing end block 309 and the articulated seat 310 that must be exposed and connected to the point rail sliding structure are designed as a disassembly structure to facilitate disassembly and maintenance.

[0029] Example 2

[0030] On the basis of Example 1, in order to make up for the problem that the device body 1 is also buried in the mine tunnel ground, which is not mentioned in Example 1, wet soil and silt completely cover the device body 1. When they penetrate into the interior of the protective box 101, they will inevitably corrode the internal components of the protective box 101.

[0031] like Figure 3 As shown, in this embodiment, a card edge 107 is fixedly installed at the edge of the upper opening of the protective box 101, and the card edge 107 is clamped with the bottom side of the sealing edge strip 108, and the sealing edge strip 108 is embedded in the bottom edge of the top cover 109; the cover lock 2 includes a lock storage sleeve 201, and a No. 1 sealing ring 202 is fixedly installed at the upper opening of the lock storage sleeve 201, and the upper opening of the lock storage sleeve 201 is slidably connected to the slide bar 203, and the upper end of the slide bar 203 is hinged with a fastener 204, and a slider storage sleeve 205 is fixedly installed on the outer surface of the lock storage sleeve 201, and a screw rod 206 is rotatably installed inside the slider storage sleeve 205 in the up and down directions, and the side surface of the screw rod 206 is screwed and connected with a lifting slider 207 fixedly connected to the slide bar 203; the lock storage sleeve 201 is fixedly installed on the front and rear side edges and the middle of the rear side surface of the two side surfaces of the protective box 101.

[0032] During specific implementation, when closing the opening on the protective box 101, the top sealing cover 109 is covered so that the groove at the bottom of the sealing edge strip 108 is engaged with the clamping edge 107. At the same time, the screw rod 206 is screwed by the nut at the upper end of the screw rod 206 to rub the lifting slider 207 downward inside the slider storage sleeve 205, driving the slide bar 203 and the lower half of the fastener 204 to be retracted into the lock storage sleeve 201. While limiting the rotation of the fastener 204, the upper half of the fastener 204 is controlled to continuously press down the edge of the top sealing cover 109, compressing the sealing edge strip 108 made of elastic material, strengthening the tightness of the connection between the top sealing cover 109 and the edge of the opening on the protective box 101, and the cylinder 103 is encapsulated through the relatively closed structure composed of the protective box 101 and the top sealing cover 109 to cope with the underground environment of the mine tunnel.
