Abstract

The utility model relates to a get stone device for following foreign matter such as stone in the tube well of getting out hangs into the tube well interior chucking stone with three activity grab bars, and the handling goes out the well.

Description

Device for grapping stone from well

The utility model is a kind of stone taking device that picks up foreign matters such as stone in the pipe well.

Before the utility model is made, people adopt the device that is referred to as " cutting ferrule tube in the spring " be contained in the drilling rod head to pick up the foreign matter that falls in the pipe well (to see " water supply well design and construction guide " 755-757 page or leaf, China Construction Industry Press, 1984,8).Because in use the spring leaf of this device can not block the different foreign matters such as stone of size and dimension securely, therefore use inconvenience.

Goal of the invention of the present utility model is to adopt a kind ofly longly to grab the three claw type movable claws that bar constitutes and extract stone by its clamping force from well with three.

Accompanying drawing 1 is a schematic diagram of the present utility model, wherein:

(1) is major axis

(2) be jump bit

(3) be the counterweight tube

(4) be basal disc

(5) be stop sleeve

(6) be threaded connecting rod rest upper end

(7) be connecting rod rest

(8) be pull bar

(9) for grabbing bar

(10) be grapple

(11) be the pull bar pivot

(12) be the connecting rod rest pivot

(13) be basal disc and the pivot that is connected of grabbing bar

(14) be hoist hook

(15) be the major axis guide pipe of basal disc upside

The utility model has adopted a diameter to be slightly less than the garden shape substrate of well inner diameter; Three ends of grabbing bar are contained in respectively on the pivot of substrate bottom surface rotationally, and this pivot is 120 ° of bottom surface circumference that are distributed in substrate; The other end of grabbing bar has grapple respectively; The pull bar pivot is equipped with at the middle part of grabbing bar, and an end of three pull bars is installed on this pivot respectively rotationally, and the other end is installed on the pivot of a connecting rod rest rotationally; A major axis passes the central axis of aforesaid substrate, penetrates the substrate downside, with screw thread the major axis lower end is connected on the connecting rod rest; Have a slip cap to be loaded on stop sleeve on the major axis between aforesaid substrate and the connecting rod rest, this stop sleeve has a radial direction through hole that bores with above-mentioned major axis cover; On aforesaid substrate, there is a slip cap to be contained in counterweight tube on the above-mentioned major axis; A hoist hook is arranged, and its lower end is connected with a jump bit; This jump bit is set on the major axis slidably, and its installation site is between above-mentioned counterweight tube and major axis upper end.

Earlier major axis is passed to the basal disc downside during use, thereby caused that connecting rod rest moves down, be horizontal until three pull bars, grab bar and open this moment.The stop sleeve that slides on major axis subsequently makes on its radial direction through hole and the long shaft rod radial direction through hole concentric, passes this 2 hole and penetrates a small wooden, and the fixed stop sleeve is on major axis, and can be lifted on hoist hook shock machine and elevator facility head this moment.Because the basal disc downside is withstood in the upper surface of stop sleeve, therefore can make and grab bar and keep deployed position to hang in the well.When package unit is put into the well precalculated position that card has stone, owing to start shock machine and hoist engine, the percussion small wooden on the stop sleeve that fractures is grabbed the bar closure for three and is blocked stone.The counterweight tube presses down basal disc with gravity, keeps grabbing bar in the clamped condition that blocks stone.Then promote a whole set of stone taking device to ground, draw off the stone that blocks.

Claims

1, a kind of pipe well stone taking device adopts and grabs stone in the bar chucking well, carries and transports well, and it is characterized in that: this device has a diameter to be slightly less than the circular substrate of borehole wall internal diameter; Three ends of grabbing bar that grasp stone are contained in respectively on the pivot of this substrate bottom surface rotationally, and this pivot is 120 ° of bottom surface circumference that are distributed in substrate; This other end of grabbing bar has respectively grabs son; The pull bar pivot is equipped with at the middle part of grabbing bar, and an end of three pull bars is installed on this pivot respectively rotationally, and the other end is installed on the connecting rod rest pivot rotationally; A major axis passes the aforesaid substrate central axis, to be threadedly connected on the connecting rod rest; Have a slip cap to be loaded on stop sleeve on the major axis between aforesaid substrate and the connecting rod rest, this stop sleeve has a radial direction through hole that bores with above-mentioned major axis cover; Upper side at aforesaid substrate has a counterweight tube that is sleeved on slidably on the above-mentioned major axis; A hoist hook is arranged, and its lower end is connected with a jump bit, and this jump bit is set on the major axis slidably, and its installation site is between above-mentioned counterweight tube and major axis upper end.
