Drain hole in the such scheme is 3; Cylindrical shell top is vertically divided two sections four working holes, and two is one group; There are two directive wheels the upper end in the cylindrical shell; Cylindrical shell has two directed pulleys outside the upper end.
The utlity model has following beneficial effect: this efficiently takes out the sand tube owing to take such scheme, utilizes hoist engine will take out the sand tube and sends into well inner product sand face, and when touching the sand face, the tube inner carrier moves down disturbance well inner product sand under the deadweight effect of counter weight.Promote by hoist engine then, the tube inner carrier is driven by movable pulley and rises, vacuum is formed at the piston bottom, produces suction, and silt sand is inhaled in the tube in the well, piston continues to rise under movable pulley drives, reciprocal in proper order, up to and top fixed pulley group between stroke hour, cylindrical shell integral body is risen to well head ground, get rid of tube inner product sand, finish and once take out the sand process.So just reaching needs the labour few, and labor strength is low, and the purpose that desilting sand efficient is high helps applying.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-cylindrical shell among the figure, 2-fixed pulley group, 3-running block, 4-counter weight, 5-piston, 6-contact, 7-valve, 8-spacer pin, 9-drain hole, 10-wire rope, 11-directive wheel, 12-movable sealing plate, 13-working hole, the directed pulley of 14-.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this is efficiently taken out the sand tube and comprises cylindrical shell 1, and cylindrical shell 1 top is vertically divided two sections, and 13, two of four working holes are arranged is one group, is convenient to fixed, running block (2,3) wire rope 10 by working hole 13 and passes through and maintenance inspection; Two directed pulleys 14 are arranged outside cylindrical shell 1 upper end, and there are two directive wheels 11 upper end in the cylindrical shell (1), and wire rope 10 enters the left side pulley that enters fixed pulley group 2 behind two directive wheels 11 through two directed pulleys 14; Cylindrical shell 1 internal upper part directive wheel 11 lower ends are fixed with fixed pulley group 2, and fixed pulley group 2 lower end counter weights 4 upper ends are fixed with running block 3, reduce hoist engine power by fixed pulley group 2 and running block 3; 3 of fixed pulley group 2 and running blocks are wound with wire rope 10, two terminations of wire rope 10 are divided and are linked to each other with 2 of fixed pulley groups and hoist engine, counter weight 4 lower end piston-rod lower ends are connected with piston 5, piston 5 axially has 3 drain holes 9, the piston 5 that drives counter weight 4 lower ends by wire rope 10 moves up and down, and increases gravity by counter weight 4; Piston 5 upper end piston rods are with and drain hole 9 corresponding movable sealing plates 12, by movable sealing plate 12 drain hole 9 are sealed when carrying on piston 5; Be fixed with up-small and down-big conical contact tip 6 in cylindrical shell 1 lower end, by conical contact tip disturbance silt sand; There are two semicircle valve 7 contact 6 upper ends by pin hinge in the cylindrical shell 1, and valve 7 upper end piston (5) lower ends are fixed with spacer pin 8, and the switch by valve 7 sucks cylindrical shell 1 with silt sand, reaches the purpose of removing silt sand.
During actual the use, at first the hoisting rope on the hoist engine is connected with wire rope 10, wire rope 10 enters the left side pulley of fixed pulley group 2 through wire rope 10 through two directive wheels 11, and again through running block 5,10 ends of wire rope are fixed on the spindle nose end of fixed pulley group 2.Hoist engine promotes running blocks 3 by wire rope 10 and rises, and drives counter weight 4 simultaneously and piston 5 rises overally, and running block 3 is taken out the sand tube and risen built on stilts during to top dead centre.
Taking out the sand tube is sent in the well by hoist engine, behind sand face in the contact 6 contact wells, cylindrical shell 1 weight acts on the sand face, piston 5 is moved downward to spacer pin 8 under the deadweight effect of counter weight 4, prevent that piston rod from producing destruction to valve 7 bumps, when simultaneously piston 5 is descending sand face in the well is produced disturbance, the water of bottom is pressed against piston 5 tops by drain hole 9.Carry wire rope 10 on the hoist engine, piston 5 rises under the effect of running block 3, movable sealing plate 12 sealing drain holes 9, and piston 5 bottoms produce vacuum, and two valve plates of valve 7 are upwards kicked up, and well inner product sand is drawn in the cylindrical shell 1, and cylindrical shell 1 integral body moves down; Put by hoist engine and to carry, running block 3 moves down at counter weight 4 effect lower pistons 5, the water of bottom is pressed against top by drain hole 9, piston 5 stops to move down during the sand face to cylindrical shell 1, drive by hoist engine once more and promote, piston 5 rises under the effect of running block 3, movable sealing plate 12 sealing drain holes 9, piston 5 bottoms produce vacuum, and well inner product sand is continued in the suction cylindrical shell 1, repeat the aforesaid operations running, stroke hour between running block 3 and fixed pulley group 2, promote cylindrical shell 1, cylindrical shell 1 leaves the sand face, and the valve plate of valve 7 is closed under the silt sand deadweight effect in tube, continue to promote cylindrical shell 1 to well head ground, open by valve 7, discharge cylindrical shell 1 inner product sand, finish and once take out the sand operation process.
The valve 7 that resets will be taken out the sand tube once more and put into well, repeat above operating process, and the full scale clearance of silt sand is clean in well.
This takes out the sand tube under the constant situation of overall structure, can change the corresponding construction size according to hole diameter, but maximum overall dimensions can not be greater than the well casing internal diameter.
In sum, this is efficiently taken out, and the sand tube is few with the labour, and labor strength is low, and desilting sand efficient height helps applying.This is efficiently taken out the sand tube to have labor strength low thus, the characteristics that desilting sand efficient is high.
