Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1 to 3, an embodiment of the present invention includes: a pneumatic underground hoisting device for a monorail crane comprises two walking trolleys 1, wherein the bottom ends of the two walking trolleys 1 are connected with a bearing cross beam 2 through a spherical hinge connecting device 3, spherical connection is adopted, the rotational freedom degree of the cross beam is increased, and displacement changes in the horizontal direction and the vertical direction of the cross beam can be automatically compensated and adjusted according to the change of the gravity center of the load when the cross beam turns horizontally and vertically, so that the load inclination and shaking caused by unstable gravity center are effectively avoided, the spherical connection not only increases the freedom degree, but also can constantly keep surface contact, and the stability of a mechanism is increased;
pneumatic hoist 4 is installed to the intermediate position of load-bearing beam 2, pneumatic hoist 4 and manual valve block 7 electric connection, manual valve block 7 is through the lifting and the locking of pneumatic pipeline control pneumatic hoist 4, the surface of pneumatic hoist 4 is equipped with two hoisting chains 5, the below at load-bearing beam 2 both ends is equipped with movable pulley device 6, the inside swing joint of movable pulley device 6 has the sprocket, hoisting chain 5 of pneumatic hoist 4 passes the sprocket of movable pulley device 6 and the other end is fixed on the surface of load-bearing beam 2, the mechanism of movable pulley group is adopted at both ends, moreover, the steam generator is simple in structure, the tonnage of lifting by crane has been doubled simultaneously.
Further, the bottom of the movable pulley device 6 is provided with a hook.
Furthermore, the pneumatic hoist 4, the hoisting chain 5 and the movable pulley device 6 form a linkage mechanism to control the lifting and the falling of the heavy-load goods.
The working principle is as follows: when the monorail crane is used, when the monorail crane runs to the position above equipment (such as a human vehicle or a material box) to be carried, the hoisting chain 5 is adjusted, hooks on the hoisting chain 5 are fixed to the equipment to be carried, the manual control valve block 7 is controlled, the hoisting chain 5 is wound up by the pneumatic hoist 4, the hoisting chain 5 passes through the movable pulley device 6, the other end of the hoisting chain 5 is fixed to one side of the bearing cross beam 2, and the hoisting chain 5 below the bearing cross beam 2 is connected with the equipment to be carried and lifted along with the movable pulley device. Because the movable pulley device 6, the pneumatic hoist 4 and the hoisting chain 5 form a set of linkage device, the pneumatic hoist 4 only bears 1/2 of the load weight, the manual control valve block 7 is operated reversely, and the equipment descends along with the manual control valve block; and when the handle of the manual control valve block 7 is released, the handle automatically returns to the middle position, the pneumatic hoist 4 is automatically locked, and the hoisting chain 5 is automatically fixed.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
