Abstract

The utility model discloses an anchor device, which is used for fixing the ground anchor bar of a directional drilling non-excavation pipe-laying driller. The anchor device comprises a bracket, a ground anchor frame and a motor revolving bed, wherein the ground anchor frame is hinged on the bracket and can rotate around the bracket, and the motor revolving bed is hinged with the ground anchor frame. The motor revolving bed is connected with the ground anchor bar. The bottom of the bracket is connected with a ground anchor plate. A plurality of ground anchor sleeves with various angles are arranged on the ground anchor plate. Compared with the prior art, the ground anchor frame can rotate around the bracket, and the driller can realize multi-angle working. The central line of the ground anchor bar is in alignment with the central line of the ground anchor sleeve. The anchor device ensures that the driller does not displace during drilling and pullout and the drilling and pullout angles of the driller do not change, and has good construction effect.

Description

A kind of anchor device

Technical field

The utility model belongs to the technical field of directional drilling trenchless pipelaying rig, relates in particular to a kind of anchor device.

Background technology

When underground utilities such as cable laying, water pipe, often to use directional drilling trenchless pipelaying rig to carry out laying construction, in practice of construction, rig creep into or the process of pulling back in, keep rig not move, otherwise then the angle that can cause rig to creep into or pull out changes, and influences construction effect, even causes the drilling rod of rig to destroy.

The earth anchor anchor device is an important component part of non-excavation pipe laying rig, solid and reliable ground anchoring drilling machine is the basis of next step construction, at present, the earth anchor anchor device exists anchoring to cause the defective that angle changes and the anchoring angle is single built on the sand in the anchoring drilling machine process.

The utility model content

Problem to be solved in the utility model provides a kind ofly can squeeze into ground anchor pole and fixedly rig and simple in structure, easy to operate anchor device in different angles.

In order to solve above-mentioned technical problem, the solution that the utility model provides is: a kind of anchor device, the ground anchor pole that is used for fixing directional drilling trenchless pipelaying rig, the ground anchor rack that comprises support, is articulated on the described support and can rotates around described support and with the motor revolving bed that can on described ground anchor rack, slide, described motor revolving bed is connected with described ground anchor pole, described frame bottom connects anchor block, and described anchor block is provided with the earth anchor cover of a plurality of different angles.

Further, also comprise a hydraulic jack, described hydraulic jack one end and described ground anchor rack are hinged, and the other end and motor revolving bed are hinged, and described motor revolving bed slip cap is located on the described ground anchor rack.

Further, set firmly a stator on the described ground anchor rack, set firmly a connecting piece on the described support, described stator is fixedlyed connected with described brace.

Further, comprise that also one places described motor revolving bed and drives the motor that described ground anchor pole rotates, described motor is connected with described motor revolving bed.

Compared with prior art, the utility model ground anchor rack can rotate around support, can be implemented in anchoring ground anchor pole on the multi-angle, and the central lines of the center line of ground anchor pole and earth anchor cover, to guarantee that rig is when creeping into or pulling back pipeline, be not moved, thereby guarantee that the angle that rig creeps into or pull out is constant, construction effect is good.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

As Fig. 1, shown in Figure 2, a preferred embodiment of the present utility model, ground anchor pole 2 is used for fixing directional drilling trenchless pipelaying rig, comprise support 3, with hinged ground anchor rack 6 of support 3 one ends and the motor revolving bed 4 that is slidingly connected with ground anchor rack 6, motor revolving bed 4 is connected with ground anchor pole 2, anchor block 1 is fixed in support 3 bottoms, anchor block is provided with four earth anchor covers 8, it is different respectively with ground vertical line angle that each earth anchor overlaps 8 center lines, ground anchor rack 6 can rotate around support 3, go to desired position and fixing, after making some central lines of center line with four earth anchor covers 8 of ground anchor pole 2, local anchor pole 2 go to another position and fixing, then can overlap in 8 another central lines with earth anchor, therefore can anchor into ground anchor pole 2 in different angles, guarantee that rig when creeping into or pull back, is not moved, thereby guarantee that rig creeps into or the angle of pulling back is constant, construction effect is good, and can realize the work of rig multi-angle.The number of earth anchor cover 8 is decided because of the practice of construction situation, is not restricted to the number in the present embodiment.In the present embodiment, support 3 and ground anchor rack 6 link together by bearing pin, are nested with bearing in the motor revolving bed 4, and bearing is used to support the rotation of gyroaxis 9, and ground anchor pole 2 is connected with gyroaxis 9 by pin.

Further, also comprise a hydraulic jack 7, one end of hydraulic jack 7 is hinged by bearing pin with ground anchor rack 6, the other end is then hinged by bearing pin with an end of motor revolving bed 4, and motor revolving bed 4 is set on the ground anchor rack 6, can slide up and down along ground anchor rack 6, thereby stretching motion along with hydraulic jack 7, motor revolving bed 4 slides up and down along ground anchor rack 6, and drives ground anchor pole 2 and move up and down, and realizes ground anchor pole 2 is crept into earth anchor cover 8 or pulls out earth anchor cover 8.

Further, be set with a stator 63 on the ground anchor rack 6, stator 63 is provided with the hole 631 of a series of circle distribution, be installed with a connecting piece 31 on the support 3, brace 31 is provided with hole 32, described ground anchor rack 6 rotates around support 3, when going to suitable angle be, can pass hole 631 on hole 32 and the stator 63 on the brace 31 by bearing pin, stator 63 and brace 31 are fixed together, thereby firm is fixed on ground anchor rack 6 on the needed angle, bores in the moving process, can avoid spot anchor pole 2 to depart from the phenomenon of the earth anchor cover 8 of aligning.

Further, also comprise a motor 5 that is located on the motor revolving bed 4, drive gyroaxis 9 by motor 5 and rotate, rotate thereby drive ground anchor pole 2.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
