Abstract
The utility model discloses a hard connection device for mining transportation equipment and belongs to the technical field of mining roadway man cars. The device comprises a short connector, a long connector, a sleeve of which an inner cavity is provided with a ball socket, and a connecting ball which is arranged in the ball socket of the sleeve, wherein a connecting hole is formed at one end of each of the short connector and the long connector; one end, which does not have the connecting hole, of the short connector is fixedly connected with one end of the sleeve; and one end, which does not have the connecting hole, of the long connector is inserted into the sleeve from the other end of the sleeve, is fixedly connected with the connecting ball in the ball socket, and can axially rotate in the sleeve together with the connecting ball. The utility model has the advantages that the device can meet the connecting requirements of various transportation devices, has a certain space rotation angle, solves the problems of the unevenness of rails in mines and the turning of roadway man cars, also solves the problems that a vehicle has low stability and big noise during operation or stop when a three-loop chain is used for connection, and can effectively improve the riding comfort; and the structure can rotate flexibly, has a compact structure, is easy to manufacture, has high traction, and can be popularized and applied.
Description
Technical field
The utility model relates to the hard connecting device of a kind of mining transportation device, belongs to mining tunnel man-bus technical field.Be mainly used in the connection of mining tunnel man-bus, also be applicable to the connection between other transportation device.
Background technology
Tunnel man-bus is the main tool of coal mine down-hole personnel transportation, adopts the chain ring type connection mode between two tunnel man-bus usually, promptly is flexible coupling; Vehicle is when starting, move and stopping, and collide each other front and back, and operation stability is poor; And noise is big, and personnel's traveling comfort is relatively poor by bus.And circumstance complication under the coal mine, personal injury accident can take place when serious in the easy safety misadventure that slides down of vehicle, has certain potential safety hazard.
Summary of the invention
In order to solve the deficiency of above-mentioned prior art, the utility model provides a kind of mining transportation device hard connecting device, is used for the connection between the tunnel man-bus.
The utility model is realized through following technical scheme: the hard connecting device of a kind of mining transportation device, and it comprises that an end respectively has a short connector and a long connector of connecting bore, an inner chamber has the sleeve of ball-and-socket and places one of sleeve ball-and-socket to connect ball; One end of the no connecting bore of described short connector is captiveed joint with sleeve one end; One end of the no connecting bore of described long connector from the other end of sleeve penetrate the sleeve connection ball captive joint in ball-and-socket and be connected ball can axially rotation in sleeve.
Two connectors of above-mentioned connecting device are connected with the two ends of tunnel man-bus respectively, and the inner ball-type type of attachment that adopts has certain space degreeof turn, have and rotate flexibly, and manufacturing is simple, compact conformation, and tractive force is big, the characteristics that angle of turn is big.
The beneficial effect of the utility model is: can adapt to various transportation device connection requests; Has certain space degreeof turn; Solved the problem that the mine lower railway is uneven and tunnel man-bus turns round; Solved vehicle operating when using ring chain to connect simultaneously or poor stability when stopping, problem that noise is big, can effectively improve ride comfort, and this structure is rotated flexibly, compact conformation, easy to manufacture, tractive force is big.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the utility model structural representation;
Fig. 2 is the tube-in-tube structure scheme drawing.
Among the figure: 1, lack connector, 2, sleeve, 3, connect ball, 4, long connector.
The specific embodiment
As shown in Figure 1, the hard connecting device of mining transportation device it have short connector 1, one long connector 4, one sleeves 2 and to connect ball 3; One end of described short connector 1 and long connector 4 is useful on and transportation device bonded assembly connecting bore, and the other end is a thread rod; One end of described sleeve 2 has the straight hole that can penetrate long connector 4 screw rods, and the other end has the end socket arrangement spherical in shape that connects with straight hole, and there is negative thread the outer end of ball-and-socket; As shown in Figure 2, described connection ball 3 cooperates with ball-and-socket, and the plane is cut at the two ends that connect ball 3, and there is the tapped bore of perforation the centre; Connect the ball-and-socket that ball 3 places sleeve 2; The thread rod of long connector 3 penetrates sleeve 2 backs and is connected ball 3 and is threaded from an end of sleeve; Long connector 4 can axially rotate with connecting ball in sleeve 2, and can certain anglec of rotation be arranged at direction in space; Short connector 1 screw rod end is screwed into ball-and-socket through being threaded io on the sleeve from the other end of sleeve 2.
For realizing the double insurance of union piece, improve tractive force, employing is threaded and welds the connection mode that combines; Also fixing after both will having lacked connector 1 and sleeve 2 being threaded with the welding of sleeve 2 outer ends.Long connector 4 be connected ball 3 be threaded the two ends, back also with is connected ball 3 welding and fixes.
Connecting bore through short connector 1 and long connector 4 ends during use is connected with mining transportation device.
