[ detailed description ] embodiments
The following description of the present invention is provided to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention and to make the above objects, features and advantages of the present invention more comprehensible.
Referring to fig. 1-3, the present invention provides a mine car connecting device 100 including two seat bodies 10 disposed opposite to each other and a connecting member 20 connecting the two seat bodies 10. The two seat bodies 10 are respectively fixed with two adjacent mine cars, and preferably, the seat bodies 10 are welded and fixed with the mine cars.
The connecting piece 20 comprises a connecting portion 21 and two bulbs 22 arranged at two opposite ends of the connecting portion 21, grooves 101 are formed in the two seat bodies 10 in a recessed mode, the bulbs 22 are contained and limited in the grooves 101 and can freely rotate in the grooves 101, and the bulbs 22 are arranged in one-to-one correspondence with the grooves 101.
Along the running direction of the mine car, the mounting height of the base body arranged at the tail end of the previous mine car is smaller than that of the base body arranged at the front end of the next mine car. The coupling 20 is mounted so that it is inclined relative to the direction of travel of the mine car. When the mine car goes up a slope, minerals in the mine car can move towards the rear end of the mine car under the action of gravity, so that the weight of the rear end of the mine car is greater than that of the front end of the mine car, the mine car is prone to tilting, and the risk of car turnover exists. Referring to fig. 3, when the mine car ascends along the X direction, because the seat body installation height of the previous mine car is lower than the seat body installation height of the next mine car, the traction force direction of the previous mine car to the next mine car is the direction F, the direction F inclines towards the slope, the direction F generates traction component force in the X direction and pressure perpendicular to the direction X, the pressure can press the front end of the mine car onto the slope, the front end of the mine car is prevented from tilting, and the stability of the mine car in the process of ascending can be improved.
The connecting part 21 is a rigid straight rod or a steel wire rope, and when the connecting part 21 is the rigid straight rod, the connecting part can bear larger pulling force; when the connecting part 21 is a steel wire rope, the steel wire rope can bear large bending, so that the steel wire rope can be reasonably selected according to the actual application scene of the mine car. For example, when the tramcar track passes through a steep slope, the connecting part 21 can be a rigid straight rod, so that the connecting part is prevented from being broken due to large pulling force in the process of ascending the slope; when the bent section of the mine car track is more, the steel wire rope can be selected, and the phenomenon that the connecting part is broken due to large bending force in the bending process is avoided.
The ball heads 22 are spherical structures, and the central axis of the connecting portion 21 and the centers of the two ball heads 22 are located on the same straight line, that is, the two ball heads 22 are symmetrically arranged at two ends of the connecting portion 21.
The shape of the recess 101 matches the shape of the outer surface of the ball head 22, i.e. the surface of the recess 101 is also spherical. The centre of a circle of recess 101 with bulb 22 is located the same point, the cross sectional shape of recess 101 is the major arc, can be right bulb 22 carries on spacingly, avoids bulb 22 follow break away from in the recess 101. The ball head 22 can rotate freely in the groove 101, and the outer surface of the ball head 22 is a smooth plane, so that the friction resistance can be reduced.
It can be understood that, by connecting the ball 22 to the seat 10, the fracture of the connecting member 20 can be largely avoided by converting the shearing force in the conventional manner into the pressing force or the pulling force; meanwhile, the contact surface between the ball head 22 and the seat body 10 is a spherical surface, which can disperse the force and reduce the loss of the ball head 22; meanwhile, the outer surface of the ball head 22 is a spherical surface, so that the contact area between the ball head and the seat body 10 can be increased, and the pressure intensity can be reduced. Furthermore, the ball head 22 can rotate freely in the groove, can adapt to the change of the running state of the mine car, has the capability of universal adjustment, and can meet the use requirements under different tracks.
Further, the seat body 10 includes an upper seat body 11 and a lower seat body 12, one side of the upper seat body 11 and one side of the lower seat body 12 are hinged through a hinge, the other side of the upper seat body and the lower seat body are locked through a lock bolt, the lock bolt includes an annular lock hole 13 and a lock pin 14 matched with the annular lock hole 13, the lock pin 14 is arranged on the upper seat body 11, and the annular lock hole 13 is arranged on the lower seat body.
The groove 101 includes an upper groove 1011 located on the upper seat body 11 and a lower groove 1012 located on the lower seat body 12. The upper and lower grooves 1011 and 1012 are symmetrically disposed about the connecting surface of the upper housing 11 and the lower housing 12. The upper seat body 11 and the lower seat body 12 are movably linked, so that the installation difficulty of the connecting piece 20 is reduced, and during installation, only the lock bolt needs to be opened, then the upper seat body 11 is turned up, the ball head 22 is placed on the lower groove 1012, then the upper seat body 11 is covered, and the lock pin 14 is detached into the annular lock hole 13, so that the upper seat body 11 and the lower seat body 12 are locked.
Compared with the prior art, the mine car connecting device provided by the invention has the advantages that two adjacent mine cars are connected through the connecting piece, the ball heads are arranged at two ends of the connecting piece, the shearing force in the traditional mode can be converted into pulling force or extrusion force, the connecting piece can be prevented from being broken, meanwhile, the mounting height of the seat body on the previous mine car is smaller than that of the seat body on the next mine car, the connecting piece is obliquely arranged relative to the running direction of the mine cars, the mine cars can be prevented from tilting in the running process, and the use stability and safety are improved.
