Description
Technical field
The utility model relates to deep foundation pit precipitation device field, relates to a kind of well point pipe drawing device particularly.
Background technology
At present, in large-scale foundation pit dewatering construction, generally all adopt light well point precipitation.When the foundation ditch structure construction arrives to a certain degree, just need pull out the precipitation light well point.Because construction process requirement, the time of pulling out the precipitation light well point is often tighter, needs to adopt a kind of method of simple and fast to pull out the well point.Existing method is to adopt the job site scaffold tubes to connect buckle, is stuck on the pipe of well point with buckle, is bundled in rope then and utilizes crane or Chain block that the well point is pulled out on the bayonet socket.Adopt this method efficient lower,, pull out the well point at every turn and all can damage a large amount of buckles because the active force contact surface is little, and because the well point pipe usually adopts UPVC to make, destroyed easily, cause damage.
Summary of the invention
Technical problem to be solved in the utility model is the existing well point method inefficiency of pulling out, damage buckle and well point easily, a kind of well point pipe drawing device is provided, this well point pipe drawing device can improve the well point and pull out efficient, can not damage the well point pipe, and make simple, easy to use, with low cost.
For solveing the technical problem, a kind of well point of the utility model pipe drawing device comprises stay cord, and this well point pipe drawing device also comprises connecting rod, eccentric wheel, transverse link and pipe watt;
Described connecting rod has four, and the hole for hoist that connects stay cord is all offered in the upper end, and the lower end of four connecting rods and the same position in stage casing are offered axis hole;
Described transverse link has four, and the place has long chute in the middle of each transverse link, is provided with the transverse link axis hole at the two ends near transverse link;
Described eccentric wheel has four, and each eccentric wheel is being respectively equipped with the first and second driving through holes apart from its center line a distance, and described eccentric both sides are installed on connecting rod and the transverse link rotationally by bolt separately;
Described pipe watt has two, each the pipe watt for the cross section be the semicircular ring cylinder, upper and lower on its outer circumference surface is provided with an alignment pin, is installed on the transverse link but described pipe watt inserts the long chute move left and right of transverse link ground by alignment pin, make two manage watt close relatively or away from.Described alignment pin is the whole projection that extends on the pipe watt wall.
For increasing pipe watt intensity, each pipe watt outside of described well point pipe drawing device also is surrounded by the steel plate of semicircular ring column.
For increasing the active force between pipe watt and the well point, a described pipe watt inner surface is lined with one deck rubber tile.
In order to strengthen the well point pipe, prevent that it from being damaged by pressure, described well point pipe drawing device also comprises a reinforced pipe, this reinforced pipe is made up of a columniform enhancing body and a T type handle that is positioned at enhancing body top.
Because the utility model is to adopt two steel pipes watt to clamp the well point steel pipe, be lined with rubber tile in the pipe watt, adopt eccentric wheel structure outward, when pulling up the well point, be subjected to the effect of upward force, eccentric athletic meeting clamps the well point automatically, and active force is big more, holds tight more.A pipe watt outside is welded with steel plate, has improved the application life of well point pipe drawing device; Because pipe watt length is longer, and because the effect of rubber tile, the frictional force of pipe watt and well point pipe is big, and the well point pipe drawing device can not come off, and can extract the well point smoothly apace; Insert the reinforced pipe that diameter and well point pipe diameter match simultaneously in the pipe of well point, prevent that effectively the well point pipe from damaging owing to being under pressure.After the well point pipe is pulled out, beat eccentric wheel downwards with blunt, pipe extractor can be thrown off voluntarily, and operation is very simple, convenient.This shows that the utility model well point pipe drawing device can improve the efficient that work is pulled out in the well point, easy to use, simple in structure, cost of manufacture is low.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the main body schematic diagram of the utility model well point pipe drawing device;
Fig. 2 is an A-A sectional drawing among Fig. 1;
Fig. 3 is the part drawing of reinforced pipe of the present utility model.
The specific embodiment
From Fig. 1, Fig. 2 and Fig. 3 as seen: a kind of well point pipe drawing device, comprise stay cord 4, this well point pipe drawing device also comprise connecting rod 1, eccentric wheel 2, transverse link 3,, pipe watts 5 and steel plate 6; Described connecting rod 1 has four, and the hole for hoist that connects stay cord 4 is all offered in the upper end, and the lower end of four connecting rods 1 and the same position in stage casing are offered axis hole;
Described transverse link 3 has four, and the place has long chute in the middle of each transverse link, is provided with the transverse link axis hole at the two ends near transverse link 3;
Described eccentric wheel 2 has four, and each eccentric wheel 2 drives through holes being respectively equipped with first and second apart from its center line a distance, and the both sides of described eccentric wheel 2 are installed on connecting rod 1 and the transverse link 3 rotationally by the location minor axis separately;
Described pipe watts 5 has two, each pipe watts 5 is the semicircular ring cylinder, the upper and lower alignment pin that is provided with on its outer circumference surface, described alignment pin is the whole projection that extends on the pipe watt wall, but described pipe watts 5 inserts transverse link 3 long chute move left and right ground by alignment pin and is installed on the transverse link 3, make two manage watts 5 close relatively or away from.In order to increase pipe watts 5 and to wait to pull out frictional force between the pipe of well point, described pipe watt 5 inner surfaces are lined with one deck rubber tile.Be reinforced pipe watts 5, the outside of described pipe watts 5 also is surrounded by the steel plate 6 of semicircular ring column.
Make for UPVC in view of the well point pipe, intensity is limited, and described well point pipe drawing device also comprises a reinforced pipe 7, and this reinforced pipe 7 is made up of a columniform enhancing body and a T type handle that is positioned at enhancing body top.
