Description
Technical field
This utility model belongs to auxiliary device field, colliery, particularly to a kind of underground coal mine mine car car arrester.
Background technology
In coal production operation, underground work is the key operation in colliery, in underground work, one main tool of conveying articles is to adopt mine car, and mine car is to utilize hoist engine as traction power, runs on the track laid, car loads the article such as coal to transport, instrument, equipment, spare and accessory parts etc.; Mostly operate in tunnel due to mine car, tunnel is to lead to arrival shaft bottom, underground from ground inclination, in mine car running, mine car bears self gravitation effect all the time, there is the trend moved downward, so when placing when mine car such as unloads the article loaded during stopping for example or load article, prevent owing to loosening occur in hoist engine or the steel wire rope of traction for example, or it is unexpected malfunctioning, just through frequently with some addition thereto, the low side of mine car is loaded the article that a stop mine car is descending, is commonly called as car arrester; Existing car arrester adopts the wedge that timber or steel are made mostly, manually place it in the side, lower end of mine car wheel, tramcar wheel is pressed on the inclined-plane of wedge, the bevel angle utilizing wedge hinders tramcar wheel descending freely rotatable, it is ensured that the generation stablizing and preventing contingency of mine car during handling article; Owing to wedge is manually to put, it is easy to be scattered and lose; If reducing the material of frictional force owing to the inclined-plane of wedge being stained with greasy dirt or other, the frictional force between wedge and rail and mine car wheel will be made to reduce, it is impossible to effective stop mine car automatically slip car; Manually place wedge owing to adopting, cause potential safety hazard to the personnel placing car arrester.
Summary of the invention
For the problems referred to above that existing underground coal mine car arrester exists, the utility model proposes a kind of underground coal mine mine car car arrester, it is characterised in that: include rail, framework, retainer ring, rotating shaft, spring, block of holding up traffic, swing arm, cylinder, control system;Described rail is laid in tunnel; Described framework is arranged on mine car needs the bottom of parking area rail; Described retainer ring is arranged on the one end of rotating shaft; Described rotating shaft is arranged in the support on framework; Described spring housing is contained in the outside of rotating shaft, and one end contacts with retainer ring, and the other end contacts with the bracket end face on framework; Described block of holding up traffic is arranged in rotating shaft, fixes with rotating shaft and is connected; Described swing arm is arranged in rotating shaft, and fixing with rotating shaft is connected, and its lower end is connected with cylinder; Described cylinder is arranged between two swing arms, and piston rod end is hinged with swing arm; Described control system is arranged in control room, including sensor, pneumatic system, controls device; Described sensor is arranged near framework.
Described block of holding up traffic includes shaft hole, swing arm, stopper; Described shaft hole is arranged on swing arm lower end; Described swing arm is positioned at the bottom of stopper, forms stepped ramp type with stopper; Described stopper is positioned at swing arm top; Described stopper bottom should be more than or equal to the spindle central distance to rail upper surface to the distance of the short transverse of shaft hole.
Described swing arm includes swing arm, rotating shaft installing hole, cylinder connecting portion; Described swing arm top is provided with rotating shaft installing hole, and the sidewall at rotating shaft installing hole is provided with screwed hole; Described swing arm bottom is provided with cylinder connecting portion, and it is vertical with sidewall that described rotating shaft installing hole is arranged on swing arm top, and its diameter is identical with shaft diameter; Described cylinder installation portion is arranged on the bottom of swing arm, and middle part is jagged, and breach sidewall has cylinder connecting hole.
Beneficial effect

Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
1. rail, 2. framework, 3. retainer ring, 4. rotating shaft, 5. spring, 6. hold up traffic block, 7. swing arm, 8. cylinder.
Detailed description of the invention
In order to further illustrate the technical solution of the utility model, in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described, such as Fig. 1, the mine car rail that in this example, two industry of selection are general is as rail 1, and is laid in tunnel according to the mode that the industry is general; Select rectangular steel pipe to be welded into rectangular frame, and a crossbeam is set therebetween, the support that two endoporus of surface configuration are concentric thereon, two bracket holes lines of centres should be parallel with rail 1 bearing of trend, using this as framework 2; Select internal diameter 30 millimeters, the annular steel of external diameter 60 mm of thickness 30 millimeters, as retainer ring 3, this example needs to adopt two retainer ring 3, and at the screwed hole of retainer ring 3 radially making national standard M6, as set screw hole; Select the round steel of diameter 30 mm length 800 millimeters as rotating shaft 4; Select the spiral compression spring of 40 millimeters of string diameter 4 millimeter pitchs of internal diameter 25 millimeters as spring 5; This example is selected commercially available double-rod cylinder as cylinder 8; Framework 2 is arranged on the bottom of the rail 1 of the position needing mine car to stop, and on it, plane contacts and parallel with rail 1 lower plane; Rotating shaft 4 is installed in 2 bracket holes of homonymy on the frame 2, and will hold up traffic block 6 and swing arm 7 to be arranged between two supports of homonymy fixing with rotating shaft 4 is connected; Being sleeved in rotating shaft 4 by spring 5 and be positioned at 2 two stent outer of framework, the end installing spring 5 in rotating shaft 4 installs and fixes retainer ring 3, adopts holding screw retainer ring 3 and rotating shaft 4 to be fastened;It is above being positioned at outside the side rail of two rails 1, is symmetrically installed above-mentioned parts in the outside of another rail 1, the cylinder rod end at the two ends of cylinder 8 is connected with swing arm 7 lower end being positioned at 1 liang of outside of rail respectively, and is connected with atmospheric control; Control system is arranged in control room, sensor is arranged near rail 1 and framework 2, this example adopts photoelectric sensor as sensor, it would however also be possible to employ pressure transducer or proximity switch etc.; This completes enforcement of the present utility model; During application, when mine car runs to and needs to stop the position loading and unloading article, sensor detects the existence of mine car, send whistle control system and send instruction, start cylinder 8, swing arm 7 is driven to rotate, thus driving rotating shaft 4 to rotate, rotating of rotating shaft 4 drives the block 6 of holding up traffic being fixed in rotating shaft 4 to swing so that block 6 of holding up traffic swings to the top of rail 1, and contact with rail 1, tramcar wheel is blocked, when having small retrogressing when mine car stops, due to the effect of spring 5, block 6 of holding up traffic to one end minute movement, can slow down the mine car impact to block 6 of holding up traffic together with rotating shaft 4; After completing loading and unloading, start hoist engine, and signal passed to control system, control system command cylinder 8 adverse movement so that block 6 of holding up traffic is swung away from rail 1, mine car just normal through.
