Description

Technical Field

[0001] The invention relates to a mine cage car stopper, in particular to a mine pneumatic remote-controlled open and close type mine cage car stopper device. Background Art

[0002] The auxiliary shaft hoisting system is the throat of the mine. It is mainly responsible for auxiliary transportation, including personnel and materials going up and down the shaft, air intake and safe exit. It is a key part in the safe production of the mine. In the process of lifting the material slag car, the tank car blocker can limit and block the mine car, fix the mine car in the cage in a designated safe position, and ensure the safe operation of the mine hoisting. If the tank car blocker fails or does not work properly, the car may run away, causing serious lifting accidents, damaging the mine shaft equipment or causing casualties.

[0003] The cages in the auxiliary shaft of our mine currently use the GDG-1.5×2×4 (small cage) and GDGK-1.5×2×4 (large cage) cages with the original car blockers. They all use a homemade hook to pull the car blocker wire rope operating rod on the car exit side to realize the material slag car exit process. The same operation is repeated hundreds of times a day. Since the car blocker is pulled and closed manually and standing at the edge of the car exit, safety accidents are prone to occur, and it often causes problems such as deformation of the operating rod and breakage of the pull rope. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a mining pneumatic remote-controlled open and close tank cage car arrester device with reasonable design, convenient operation and good safety.

[0005] The technical solution of the present invention is: A pneumatic remote-controlled open and close tank cage arrester device for mining, comprising an opener and a cylinder, the outer end of the push rod of the cylinder being rotatably connected to the inner end of a changing link, the lower end of the cylinder being connected to a support plate, a changing slide being also provided on the support plate, the opener and the closeer being slidably connected to the opener and closeer slide rail, the opener and closeer slide rail being provided on the tank cage, a connecting rod guide groove being provided on the opener, the changing link being able to pass through the changing slide rail and the outer end extending into the connecting rod guide groove, the extension and retraction of the cylinder push rod driving the opener and the closeer to move back and forth, guiding the tank cage arrester to achieve an open and reset state.

[0006] Furthermore: the direction-changing slideway is made of a steel plate, and plasma cutting is used to form a hollow transverse "L" shape on the steel plate. The upper portion of the steel plate is heated and bent to a required direction-changing angle to guide the movement of the direction-changing connecting rod.

[0007] Furthermore, a circular bearing is mounted on the outer end of the push rod, a threaded through hole is drilled at the center of the edge of the bearing seat for assembling the direction-changing connecting rod, and a sleeve is sleeved on the direction-changing connecting rod, and the two are rollingly matched.

[0008] Furthermore: a threaded section is arranged on the push rod outside the tile seat, a locking nut is screwed on the threaded section, and a threaded hole and a pin are arranged at the same time, so as to enable positioning and prevent falling off.

[0009] Furthermore: a spring buffer mechanism is provided at the lower end of the support plate, and the spring buffer mechanism includes a fixed plate and a fixed sleeve. There are two fixed sleeves that are fixed on the fixed plate in parallel and at intervals. A spring and a movable sleeve are respectively provided in each fixed sleeve. A strip seam is provided on the upper tube wall of each fixed sleeve, and a connecting plate is provided through the strip seam. The lower end of the connecting plate is connected to the tube wall of the movable sleeve, and the upper end of the connecting plate is connected to the support plate.

[0010] Furthermore: Angle irons are respectively provided at both ends of the fixing sleeve, and the angle irons are connected to the fixing plate by bolts, so that they can stop leaks and can be disassembled and assembled.

[0011] Furthermore: a support leg is provided at the lower end of the fixing plate, and the lower end of the support leg is connected to the foundation or the fixing member to support the entire spring buffer mechanism.

[0012] Furthermore: bearings are respectively arranged at the four corners of the shutter to facilitate rolling connection with the shutter slide rail, two connecting rod guide grooves are arranged at intervals in the middle of the shutter, and a weight-reducing hole is arranged on the shutter.

[0013] Furthermore: the air intake and exhaust of the cylinder are controlled by a mine-used intrinsically safe pneumatic driver-controlled turnout device controller, and the mine-used intrinsically safe pneumatic driver-controlled turnout device controller is used in conjunction with a mine-used intrinsically safe driver-controlled turnout display, a mine-used intrinsically safe wireless transmitter and a mine-used explosion-proof and intrinsically safe DC regulated power supply. Its working principle is: press the mine-used intrinsically safe wireless transmitter to control the controller solenoid valve through the internal control panel of the display, so that the cylinder push rod moves out or in. If the display originally displays "↑", it will change to "←", and vice versa, the display result is the opposite; if the cylinder push rod is not in place within 5 seconds during the extension process, the two indicator lights will light up at the same time and an alarm will be sounded; if the two proximity switches touch the cylinder push rod at the same time during use, the two indicator lights will light up at the same time and an alarm will be sounded; if the two proximity switches cannot touch the cylinder push rod at the same time, the two indicator lights will also light up at the same time and an alarm will be sounded.

[0014] The beneficial effects of the present invention are: 1.

It is safe and efficient, greatly reducing the workload of workers and truly realizing automation.

[0015] 2. The present invention adopts a direction-changing slideway and a direction-changing connecting rod to ensure that the cylinder guide connecting rod remains in a vertical state after being recovered, and does not affect the normal operation of the cage.

[0016] 3. The present invention uses a spring as a buffer to reduce the thrust generated by the cylinder push rod during the forward pushing process. In addition, two sets of spring sleeves are used in parallel to balance the stability of the cylinder buffer and prevent the left and right swinging phenomenon from occurring.

[0017] 4. The shutter slide rail of the present invention is mainly composed of two fixed steel plates, which are positioned and punched on the side channel steels of the large and small cages, and connected with anti-loosening bolts to keep the upper and lower levels consistent, leaving enough space for the shutter to run on this track, and ensuring that the shutter does not derail or fall during the operation of the cage, thereby guiding the back and forth movement of the shutter.

[0018] 5. In order to reduce the weight of the switch, the present invention reduces the overall dimensions to 750×350mm, and the two rectangular holes in the middle are cut into 350×53mm and 620×96mm respectively. While ensuring strength and aesthetics, 19 circular through holes with a diameter of 24mm are distributed and cut around. The sides of the two holes in the middle are welded in single-sided sections to ensure that the four corner bearings can be disassembled in case of damage, which is convenient for replacement and lubrication of the bearings.

DETAILED DESCRIPTION

[0021] Example: See Figure 1 -- Figure 7 In the figure, 1-cylinder, 2-opener, 21-connecting rod guide groove 21, 22-weight reduction hole, 23-bearing, 3-direction changing connecting rod, 4-direction changing slideway, 5-opener and closer slide rail, 6-buffer spring mechanism, 7-bracket, 8-pull rod, 9-tank cage stopper, 61-angle iron, 62-connecting plate, 63-strip seam, 64-movable sleeve, 65-fixed sleeve, 66-spring.

[0022] A pneumatic remote-controlled open and close tank cage arrester device for mining, comprising an opener 2 and a cylinder 1, wherein: the outer end of the push rod of the cylinder 1 is rotatably connected to the inner end of the change-direction connecting rod 3, the lower end of the cylinder 1 is connected to a support plate, a change-direction slide 4 is also provided on the support plate, the opener 2 is slidably connected to an opener slide rail 5, the opener slide rail 5 is provided on the tank cage, a connecting rod guide groove is provided on the opener 2, the change-direction connecting rod 3 can pass through the change-direction slide 4 and the outer end extends into the connecting rod guide groove, the extension and retraction of the cylinder push rod drives the opener 2 to move back and forth, and guides the tank cage arrester to realize the opening and resetting states.

[0023] Optimal solution: Since the cage is in dynamic operation, the device must be separated from the shutter installed on the cage during and after operation to ensure that the cylinder change-of-direction connecting rod remains vertical after recovery and does not affect the normal operation of the cage. Therefore, the cylinder actuator is installed at the wellhead and the bottom of the well. The cylinder's contraction is a horizontal or vertical action, and the actuator is usually connected by a fixed bolt, which cannot meet the working needs of this design. Therefore, the cylinder push rod is required to perform the change of direction action. According to the stroke of the cylinder push rod, the change-of-direction slide 4 is made of 8mm thick steel plate, and plasma cutting is used on the steel plate to form a hollow horizontal "L" shape. The upper part of the steel plate is heated and bent to the required change of direction angle to guide the movement of the change-of-direction connecting rod.

[0024] A circular bearing with an outer diameter of 45mm is installed at the top thread of the push rod. A threaded through hole with a diameter of 10mm is drilled at the center of the edge of the tile seat to assemble the direction-changing connecting rod 3 with a diameter of 18mm and a length of 140mm. A sleeve with a diameter of 20mm is placed on the direction-changing connecting rod 3. The two are connected in a rotating manner to ensure that the direction-changing connecting rod 3 rolls when changing direction, reduce friction, and while tightening the direction-changing connecting rod 3, it also plays a role in positioning the outer edge of the internal bearing to ensure that the direction-changing connecting rod 3 can change direction freely under the action of the bearing movement. At the same time, a locking nut and a threaded hole pin are installed on the outside of the tile seat to prevent the direction-changing connecting rod 3 from loosening and falling into the wellbore during the reciprocating direction-changing process to the greatest extent. Secondly, the threaded connection is used to facilitate maintenance and replacement of parts.

[0025] Optimal solution: Considering that the cylinder will generate a strong thrust during the extension and retraction process, if the direction-changing connecting rod 3 cannot stop the action after driving the shutter 2 on the cage to the right position, the connecting parts will be damaged by the force, thereby causing the weak part of the direction-changing connecting rod 3 to deform or break. This requires the installation of a force unloading device to reduce the thrust. This spring buffer mechanism uses two springs 66 with a wire diameter of 8mm, an outer diameter of 40mm, and a total length of 200mm, which are installed in two sets of 50 galvanized steel pipes (i.e., fixed sleeves 65). The tail of the spring 66 uses two sleeves with a length of 200mm and a diameter of 40mm (i.e., movable sleeves 64) as recoil support springs. The front end of the spring 66 is connected with a 40mm angle iron 61 bolt as a spring front end baffle, which is easy to disassemble and replace the spring. The upper side pipe wall of each fixed sleeve 65 is provided with a strip seam 63, and a connecting plate 62 is provided through the strip seam 63. The lower end of the connecting plate 62 is connected to the pipe wall of the movable sleeve 64, and the upper end of the connecting plate 62 is connected to the support plate, so as to reduce the thrust generated by the cylinder push rod during the forward pushing process, and use the spring device as a buffer. The reason why two sets of spring sleeves in parallel are used as buffer devices is mainly to balance the stability of the cylinder buffer and prevent the left and right swinging phenomenon from occurring.

[0026] Preferred solution: A support leg 7 is provided at the lower end of the fixing plate, and the lower end of the support leg 7 is connected to the foundation or the fixing member to support the entire spring buffer mechanism.

[0027] Optimal solution: bearings 23 are provided at the four corners of the shutter 2 to facilitate rolling connection with the shutter slide rail 5. Two connecting rod guide grooves 21 are provided at intervals in the middle of the shutter 2. In order to reduce the weight of the shutter 2, the outer dimensions are reduced to 750×350mm. The two rectangular connecting rod guide grooves 21 in the middle are cut into 350×53mm and 620×96mm respectively. While ensuring strength and beauty all around, 19 circular weight-reducing holes 22 with a diameter of 24mm are distributed and cut.

[0028] The air intake and exhaust of the cylinder is controlled by the mine intrinsically safe pneumatic driver-controlled turnout device controller 84. The mine intrinsically safe pneumatic driver-controlled turnout device controller 84 is used together with the mine intrinsically safe driver-controlled turnout display 82, the mine intrinsically safe wireless transmitter 81 and the mine flameproof and intrinsically safe DC regulated power supply 83. Its working principle is: press the mine intrinsically safe wireless transmitter 81, and control the controller solenoid valve through the internal control panel of the display 82, so that the push rod of the cylinder 1 goes out or in. If the display originally displays "↑", it will change to "←", otherwise, the display result will be opposite; if the cylinder push rod is not in place within 5 seconds during the extension process, the two indicator lights will light up at the same time and alarm; if the two proximity switches touch the cylinder push rod at the same time during use, the two indicator lights will light up at the same time and alarm; if the two proximity switches cannot touch the cylinder push rod at the same time, the two indicator lights will also light up at the same time and alarm. In the figure, the number 85 represents the air pipe, and the number 86 represents the cable.

[0029] Function: This device has a transmitter that sends out a control signal. After the display receives the signal, it opens the pneumatic valve to drive the cylinder to move, so that the cylinder push rod extends or retracts, and guides the direction-changing connecting rod to drive the opener and closer to drive the car blocker in the tank cage to open or reset. At the same time, the actuator gives an in-position feedback signal to the display. The display displays whether the opener and closer are in place according to the in-position feedback signal. The direction indicated by the green arrow means that the opener and closer has been pushed into place and the trolley operation can be carried out. When the red round light is on, it means that the opener and closer is not in place and the trolley operation cannot be carried out.

[0030] The present invention is controlled by a remote control device, which controls the extension and retraction of the cylinder through a control box, and guides the connecting rod through the interaction between the changing track and the cage opener and closeer through the piston push rod, so that the car blocker is rotated and the opening and closing of the car blocker is realized. After installation, testing and use, the device is convenient and fast, saves time and labor, and has reliable operation, safety and efficiency, improves transportation efficiency, eliminates the safety hazards of manual operation, ensures the safe operation of the equipment, adds a safety guarantee for mine transportation, and is an excellent design worthy of promotion.

[0031] Optimal solution: Considering the problem that the cage may not be in place due to personnel accidentally touching the remote control transmitter during the operation of the cage, or the cage can be operated but not locked during operation, it is determined to install a locking device on the cradle. The working principle of the locking device is that the cradle landing sensor on the cage outgoing side controls the relay K1 in the explosion-proof box of the vehicle operation and signal system, and then a pair of normally open auxiliary contacts of the relay K1 controls the DC12V power supply of the pneumatic driver-controlled turnout device control box. When the cradle on the outgoing side falls into place, the relay K 1 coil is energized, its normally open auxiliary contact is closed, the control box of the pneumatic driver-controlled turnout device obtains the DC12V control power supply, and the driver-controlled turnout device can be put into operation; when the cradle on the outgoing side is lifted, the relay K1 coil loses power, its normally open auxiliary contact is disconnected, the control box of the pneumatic driver-controlled turnout device has no DC12V control power supply, and the driver-controlled turnout device cannot be put into operation, so that the DC12V control power supply of the driver-controlled turnout is energized only when the cradle on the outgoing side falls into place, which improves the locking relationship and ensures the safety of the cage and automatic car blocker equipment.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification made according to the technical essence of the present invention still falls within the scope of the technical solution of the present invention.
