Description

A kind of open and close type rig guiding device
Technical field
The utility model relates to a kind of rig guiding device, especially relates to a kind of open and close type rig guiding device.
Background technology
Guiding device is in foundation construction rigs such as long-spiral drilling machine, multiaxis diaphragm wall rig, to be used for drilling rod is played location and a kind of device of guide effect.There is following shortcoming in existing guiding device:
Integral body is closed or semi-enclosed structure, can not open or open fully, can stop that drill power head is descending, thus the degree of depth that reduces to creep into;
Assembling and dismounting the time must let drilling rod from casing, pass, and abdicate behind the space of casing height could implementation and operation, and the gap between casing and the drilling rod is generally all smaller, and mounting or dismounting are inconvenient.
The utility model content
The utility model aims to provide a kind of rig guiding device, to solve the defective that exists in the above-mentioned prior art.
The purpose of the utility model is realized by following technical proposals: a kind of open and close type rig guiding device comprises being closed into holistic first guide protective tube, second guide protective tube; First link that is fixedly connected with said first guide protective tube; Second link that is fixedly connected with said second guide protective tube; Two ends respectively with said first link and the first hinged telescoping mechanism of borer frame; Two ends respectively with said second link and the second hinged telescoping mechanism of borer frame; Said first link rotatably is connected on the borer frame away from first guide protective tube, one end; Said second link rotatably is connected on the borer frame away from second guide protective tube, one end; Said first guide protective tube of the flexible promotion of said first telescoping mechanism closes up or opens, and said second guide protective tube of the flexible promotion of said second telescoping mechanism closes up or opens.
Further, said first telescoping mechanism and second telescoping mechanism are telescopic oil cylinder, electric pushrod, Electrohydraulic push rod, mechanical type thread transmission etc.
The cross sectional shape of the casing endoporus after further, said first guide protective tube, second guide protective tube close up is waist shape, circle, rectangle, " candied haws on a stick " shape, ellipse etc.
Further, said first link is connected on the borer frame away from rotating mechanism, thrust bearing or the pivoting support of second guide protective tube, one end through perforate on hinge, the borer frame away from first guide protective tube, one end and said second link.
Further, said first guide protective tube, second guide protective tube are provided with fixed pin holes, when two guide protective tubes are closed, through Fixed latches two guide protective tubes are connected into one.
Two guide protective tubes of this open and close type rig guiding device are realized opening or closing up under first telescoping mechanism and the second telescoping mechanism effect, and when unit head did not pass through the casing position, casing just was in and closes up state, plays the guide-localization effect.When unit head will pass through the casing position, then casing is opened, let unit head pass through, continue to creep into downwards, thereby can increase the degree of depth of creeping into.
The utility model brings following beneficial effect: can realize the function that leads and locate, can not stop that again unit head is descending, can increase the drilling depth of a casing height at least simultaneously; The open and close type structure makes dismounting more convenient, and does not receive the restriction of drilling rod and casing relative position.
Description of drawings
The accompanying drawing that constitutes the part of the utility model is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 is an embodiment rig guiding device structural representation;
Fig. 2 is embodiment rig guiding device casing open configuration figure;
Fig. 3 is single rig installation and guide device sketch map that bores;
Fig. 4 is three diaphragm wall rig installation and guide device sketch mapes.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further.
Like Fig. 1, open and close type rig guiding device shown in Figure 2, first guide protective tube 1 is fixedly connected on first link 9; Second guide protective tube 3 is fixedly connected on second link 5; First link 9 is provided with the two sections connecting bushing and is hinged on the borer frame 8 through hinge 10, and second link 5 is provided with the two sections connecting bushing and is hinged on the borer frame 8 through hinge 6; First telescopic oil cylinder, 11 two ends are hinged on respectively on first link 9 and the borer frame 8; Second telescopic oil cylinder, 7 two ends are hinged on respectively on second link 5 and the borer frame 8; Flexible promotion first guide protective tube 1 of first telescopic oil cylinder 11 closes up or opens, and flexible promotion second guide protective tube 3 of second telescopic oil cylinder 7 closes up or opens; Coupling ground is provided with fixed pin holes 2 and 4 on first guide protective tube 1, second guide protective tube 3, when two guide protective tubes closure, through Fixed latches two guide protective tubes is connected into one.
As shown in Figure 3; When rig began to creep into, first guide protective tube 1, second guide protective tube 3 were in and close up state, and drilling rod 13 passes through in cylinder; Its space is a bit larger tham the external diameter of drilling rod 13 helical blades, and casing just can play guiding and positioning action well like this.When rig continues to bore down; When unit head 12 constantly goes downwards near guide protective tube; The Fixed latches that connects first guide protective tube 1, second guide protective tube 3 is extracted, shunk first telescopic oil cylinder 11 and second telescopic oil cylinder 7 then first guide protective tube 1, second guide protective tube 3 are opened, abdicate the descending space of unit head 12; Unit head continues descending promotion drilling rod 13 again and creeps into downwards, thereby can increase the drilling depth of a casing height easily.
As shown in Figure 4, guiding device is installed on three diaphragm wall rigs, and the casing endoporus that this moment first, guide protective tube 1, second guide protective tube 3 formed when closed is " a waist shape ".
The above is merely the preferred embodiment of the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit and principle that the utility model claim limits, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of utility model.
