Abstract
The utility model belongs to the technical field of excavating equipment on excavating working surfaces under wells of coal mines, in particular relates to a flexible rotation device for a support retraction tractor with a stable mechanism. By the flexible rotation device, the problem that when a large-mining height hydraulic support retracts under a well of the conventional coal mine, the hydraulic support can be withdrawn by the conventional support carrier is solved. The flexible rotation device comprises a flexible mechanism and a rotation lifting body, wherein the flexible mechanism comprises a fixed cylinder and a flexible cylinder which can do flexible motion relative to the fixed cylinder; one end of the rotation lifting body is connected with the fixed cylinder to form left and right rotation pivot points, and the other end of the rotation lifting body is provided with a connecting structure which is connected with a machine frame of a tractor in a rotational mode; two rotation oil cylinders which are symmetrical relative to the fixed cylinder are arranged on two sides of the fixed cylinder; one end of each of the two rotation oil cylinders is connected with the fixed cylinder, and the other end of each of the rotation oil cylinders is connected with the rotation lifting body; the bottom of the rotation lifting body is connected with a support oil cylinder; and the support oil cylinder is connected with a support leg. The flexible rotation device has the advantages of flexible action, high stability, large traction force and large rotation angles.
Description
Technical field
The utility model belongs to the technical field of driving face heading equipment under the coal mine, is specifically related to a kind of flexible slewing equipment that has the rack restoring tractor of stabilizing mechanism, is mainly used in returning of tunnel working surface hydraulic support and removes.
Background technology
Big mining height hydraulic support returns when removing under the existing coal mine, and the conventional stent carrier can not be withdrawn from hydraulic support.
Because big mining height hydraulic support Heavy Weight, volume is big, and because the restriction of span length, bracket carrier can not directly be withdrawn from big mining height support from work plane.
Summary of the invention
The utility model returns when removing in order to solve under the existing coal mine big mining height hydraulic support, and the conventional stent carrier can not be withdrawn from the problem of hydraulic support, and a kind of flexible slewing equipment that has the rack restoring tractor of stabilizing mechanism is provided.
The utility model adopts following technical scheme to realize:
The flexible slewing equipment that has the rack restoring tractor of stabilizing mechanism; It is characterized in that it comprises telescoping mechanism and rotary and lifting body; Telescoping mechanism comprises the stationary magazine creel and the retracting cylinder of its stretching motion relatively, and rotary and lifting body one end is connected with stationary magazine creel and forms hinge point turning left and right, and the other end setting of rotary and lifting body can form the syndeton that is rotationally connected with the tractor frame; The stationary magazine creel both sides are provided with two angling cylinders of its symmetry relatively; One end of two angling cylinders is connected with stationary magazine creel respectively, the other end is connected with the rotary and lifting body respectively, and rotary and lifting body bottom connects support cylinder, and support cylinder connects supporting leg.Left and right sides angling cylinder is in turning course, and turning power can change with the variation of angle of revolution, adapts to the operating mode that hydraulic support is withdrawn from, and has solved the difficult problem of turning power from diminishing greatly when hydraulic support is withdrawn from.
The relative prior art of the utility model has following beneficial effect: adopt the flexible slewing equipment that has stabilizing mechanism; Strengthen the rack restoring tractor in the down-hole job stability during the towing hydraulic support, reach flexible flexible, easy to operate, the complete machine stability of revolution and reach tractive force purpose stably well.Have flexible movements, good stability, tractive force is big and the angle of revolution is big advantage; Solved the problem that turning power can change with the variation of angle of revolution; Improved the speed that the hydraulic support of work plane is withdrawn from, made it to become the large-mining-height working surface hydraulic support and return the optimal selection of removing.Overcome the problem that bracket carrier can not pull out hydraulic support near work plane, realized the short distance towing of the big mining height hydraulic support of work plane, operating mode that suitable hydraulic support is withdrawn from, practical.
Description of drawings
Fig. 1 is the structural representation of the utility model
Among the figure: 1-retracting cylinder, 2-stationary magazine creel, 3-angling cylinder, 4-rotary and lifting body, 5-support cylinder, 6-supporting leg.
The specific embodiment
Be described further in conjunction with the specific embodiment of accompanying drawing to the utility model, embodiment is used for explaining the utility model, rather than it is done any restriction.
The flexible slewing equipment that has the rack restoring tractor of stabilizing mechanism; It comprises telescoping mechanism and rotary and lifting body 4; Telescoping mechanism comprises the stationary magazine creel 2 and the retracting cylinder 1 of its stretching motion relatively, and rotary and lifting body 4 one ends are connected with stationary magazine creel 2 and form hinge point turning left and right, and the other end setting of rotary and lifting body 4 can form the syndeton that is rotationally connected with the tractor frame; Stationary magazine creel 2 both sides are provided with two angling cylinders 3 of its symmetry relatively; One end of two angling cylinders 3 is connected with stationary magazine creel 2 respectively, the other end is connected with rotary and lifting body 4 respectively, and rotary and lifting body 4 bottoms connect support cylinder 5, and support cylinder 5 connects supporting leg 6.
During work; Hydraulic support is fixed on retracting cylinder 1 front end; Revolution through angling cylinder 3 can make about the telescoping mechanism that is installed on the rotary and lifting body turns round, and through the flexible of the inner telescopic oil cylinder of telescoping mechanism hydraulic support is moved forward and backward, supporting leg 6 can be under the effect of support cylinder 5 kiss the earth; Thereby the stability when strengthening work, all axial, transverse loads all pass to frame through the rotary and lifting body.
