Description of drawings
Fig. 1 is the scheme drawing of hoisting pressure device of the present invention.
The specific embodiment
See also shown in Figure 1ly, hoisting pressure device of the present invention comprises the elevator frame 5 that is set on the unit head link span 6, and reel 1 is installed on elevator frame 5.Do not need to be provided with spacer ring in the middle of the reel 1 that adopts in the present invention.Usually can adopt usual manners such as casting or welding to make reel 1.One end of one end of described first steel rope 21 and second steel rope 22 is fixed on the two ends of reel 1 respectively.The other end of first steel rope 21 is connected with unit head link span 6 by the last fixed pulley 31 that is fixed on mast (not shown) top.The other end of second steel rope 22 is connected with unit head link span 6 by the following fixed pulley 32 that is positioned at unit head link span 6 belows.
In a preferred embodiment, as shown in fig. 1, the other end of first steel rope 21 is connected with first stretching device 41 on being fixed on unit head link span 6 by last fixed pulley 31.The other end of second steel rope 22 is connected with second stretching device 42 on being fixed on unit head link span 6 by following fixed pulley 32.Usually, first stretching device 41 or second stretching device 42 are hydraulic actuating cylinders, also can adopt air cylinder as required.
In another preferred embodiment, as shown in fig. 1, elevator frame 5 is fixedly connected by welding together with unit head link span 6.For the ease of I﹠M, can elevator frame 5 and unit head link span 6 removably be linked together by bolt or similar attaching parts.
In another preferred embodiment, can provide power by retarder (not shown) to reel 1 by HM Hydraulic Motor or electrical motor.
In order to simplify the structure of ground construction machinery and equipment, especially simplify the structure of rotary drilling rig, can will descend fixed pulley 32 to be fixed on the bottom of mast (not shown).Also can the frame of mast will be descended fixed pulley 32 to be fixed on to be used to support as required.
Below the concise and to the point working process of describing hoisting pressure device of the present invention.As shown in Figure 2, elevator frame 5 and unit head link span 6 are made integral structure by welding.Be used to drive the HM Hydraulic Motor that reel 1 rotates and be installed in unit head link span 6.Reel 1 is installed in rotation on the elevator frame 5.Because an end of first steel rope 21 and an end of second steel rope 22 are fixed on the two ends of reel 1 respectively.The other end of first steel rope 21 is connected with unit head link span 6 by the last fixed pulley 31 that is fixed on mast (not shown) top.The other end of second steel rope 22 is connected with unit head link span 6 by the following fixed pulley 32 that is positioned at unit head link span 6 belows.When reel 1 clockwise rotated in the direction of arrow A, second steel rope 22 was continued to be involved in reel 1, produced downward pulling force by 32 pairs of unit head link spans of second fixed pulley 6 thus, promptly implemented stress downwards.When reel 1 when the arrow B direction rotates counterclockwise, first steel rope 21 is continued to be involved in reel 1, thus first steel rope 21 by 31 pairs of unit head link spans of first fixed pulley 6 produce upward to pulling force, i.e. pulling force.Because hoisting pressure device that steel rope and pulley constitute and unit head link span 6 form integral structure, at reel 1 conter clockwise or when clockwise rotating, it is along with unit head link span 6 is done the motion of direction up or down together, and pulling force that makes progress and downward pressure that win steel rope 21 and second steel rope 22 are applied have obtained double amplification effect.
