The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As Fig. 1, Fig. 2, the structure of the utility model device comprises upper frame, lower frame and lifting gear.
With reference to Fig. 3, upper frame comprises that vertically disposed two vertical rods 3, horizontally disposed sleeper beam 1 and 2, two vertical rods 3 of crossbeam, sleeper beam 1 and crossbeam 2 form trussed constructions, is symmetrically installed with two support bars 4 along the vertical center line both sides of crossbeam 2 soffits; Have several equally spaced pin shaft holes 18 in the vertical rod 3, the distance between the pin shaft hole 18 is the adjustable minimum range of mounting bracket short transverse.
With reference to Fig. 4, lower frame is included in a tail trimmer 5 respectively is installed on the left and right column 7, and the inner lower edge of each tail trimmer 5 is provided with an otic placode 6, is provided with ladder 8 between tail trimmer 5 and the fork truck beam 10, and dead line otic placode 9 and puffer 11 are installed on the fork truck beam 10.
Have two pin shaft hole B19 on the column 7 in the lower frame, and the spacing of the pin shaft hole 18 in the spacing of pin shaft hole B19 and the vertical rod 3 equates, vertical rod 3 can move up and down in column 7, when the pin shaft hole in the vertical rod 3 18 alignd with column 7 upper pin hole B19, inserting bearing pin can be connected and fixed upper frame and lower frame reliably.
With reference to Fig. 1, Fig. 2, jacking system comprises the puffer 11 that is installed on the fork truck beam 10, in the lower end of support bar 4 lifting pulley 13 is installed, crossbeam 2 soffits are equipped with fixed pulley 16, are fixed to dead line otic placode 9 after the rope 12 of drawing from puffer 11 passes fixed pulley 16, the movable pulley 15 that is connected with tripod 14, fixed pulley 16 successively; Fixed length rope 17 is got back to opposite side lifting pulley 13, the otic placode 6 from a pick up the ears plate 6, lifting pulley 13, tripod 14.The power of puffer 11 be pneumatic, surge or manually, puffer 11 has self-locking device.
With reference to Fig. 5, the ground connection crossbeam of lower frame is made as two fork truck beams 10, and fork truck can move entire bracket by the entry in the fork truck beam 10, and is not only easy to operate, and saved large-scale hanging device.
The operating principle of the utility model device is,
When 1) needing the rising support to be used as the high trestle use, operation is installed in the puffer 11 on the lower frame, slow retraction cables 12, rope 12 passes fixed pulley 16 drive movable pulley 15 and tripod 14 moves up together, be connected with two fixed length ropes 17 on the tripod 14, the other end of fixed length rope 17 passes lifting pulley 13 and is connected with otic placode 6.Tripod 14 drives lifting pulley 13 by fixed length rope 17 and moves up, and lifting pulley 13 is being with support bar 4 to move up again, and support bar 4 is being with upper frame to move up together.When upper frame is moved upwards up to needed height, locking puffer 11, make upper frame keep motionless, can climb the fixed pin shaft that ladder 8 is installed pin shaft hole 18 and column 7 upper pin hole B19 in the vertical rods 3 this moment, just can normally use after bearing pin installs;
2) need to reduce support, when being used as low trestle and using, locking puffer 11 is climbed ladder 8 dismounting bearing pins then earlier, because puffer 11 tension ropes, so dismantled not landing downwards of upper frame behind the bearing pin.Can operate puffer 11 this moment, slowly discharges rope 12, under the effect of upper frame deadweight, can force support bar 4 being with two groups of lifting pulley 13 to move down, and tripod 14 dragged by two ropes 17 of lifting pulley 13 drives and movable pulley 15 moves down together.When upper frame is moved down into needed height, locking puffer 11, make upper frame keep motionless, can climb the fixed pin shaft that ladder 8 is installed pin shaft hole 18 and column 7 upper pin hole B19 in the vertical rods 3 this moment, just can normally use after bearing pin installs.
Derrick installation support of the present utility model is placed on front side, ramp, rig substructure gate, is used to lay the derrick that is in level.The column of vertical rod 3 in lower frame that can control in the upper frame by the puffer 11 in the operation jacking system moves up and down for 7 li, thereby regulate the height of whole derrick installation support, when being adjusted to the height that needs, with bearing pin upper frame and lower frame are connected as one, can use as ordinary stent.
