Abstract
The utility model provides a setting position of fixed steel wire or pipe etc. in ground drilling is used for measuring different degree of depth ground displacement volume or downthehole locator of installing the sensor. The connector is in friction connection with the mounting rod through a plurality of raised burrs on the surface of the connector; the spring claw is restrained by the restraining ring, can automatically open to support the rock wall for positioning after the restraint is removed, can set a fixed point or a measuring point at any position according to requirements, and can work after being accurately positioned and fixed by the mounting rod. The novel positioning device is simple in structure, convenient to install and reliable in positioning.
Description
The utility model relates to a kind of Rock and Soil Drilling hole locator, especially can be used for measuring different depth rock displacement amount or in the hole certain depth install sensor and use.
Steel wire, bar, the pipe localization method of instruments such as existing multiple position extensometer or boring absciss layer instrument in boring mainly contains three kinds of mechanical type, glued formula and expansion types, mechanical type is implemented in the hole wall by the operation transmission mechanism and locatees, and cementitious materialss such as glued formula employing cement are fixed; Expansion type is by the wet dilatancy stationary positioned in boring of compressed wood.All there is following weak point in these methods: 1. mechanically because of its mechanism's complexity instrument is cost an arm and a leg, and locator is expendable material, this just causes the use cost height.2. operation in boring, as it is difficult to smash operation such as injecting glue knot material, thereby be difficult to guarantee the reliability of locating.3. the compressed wood expanded size is determined by relative humidity variations, so its fixing firm degree is subjected to environmental influence big, and functional reliability is poor.4. glued formula or compressed wood expansion type can not be worked after installing immediately.5. the pipe seam formula anchor head that emerges is recently installed difficulty.
The purpose of this utility model is to provide a kind of intrinsic elastic property of material of utilizing in order to overcome above-mentioned the deficiencies in the prior art part, after removing constraint, can realize the novel locator of locating in hole wall generation effect, remove constraint and can finish good positioning effect at oral pore.
Task of the present utility model is implemented as follows, a kind of ground boring inner spring pawl formula locator, it comprises stay cord, pin and steel wire, comprise that also connector is a pipe, its right-hand member head has the burr of a plurality of projectioies, the left end of pipe is equipped with spring claw hook, pin is equipped with at the middle part, be connected with steel wire on the pin, confinement ring arranged, be connected with confinement ring by pin rod in the spring claw hook upper end, the spring claw hook binding is constrained in the connector two side, the Kong Zhongshuan of pin rod right-hand member head has stay cord, is connected by friction between connector and mounting rod, and mounting rod is an expansion link; In locator is sent into boring during desired location, take out the constraint of pin rod removal after, the spring claw hook on the connector promptly opens automatically, support is to the crag of holing, hook is finished locator is fixed in the hole by elastic force and is worked on the desired location.
The utility model compared with prior art has the following advantages: the spring claw hook that this locator utilizes elastomeric material to make, after its removal constraint, can strut automatically and be fixed on and locate on the crag, need not the complicated mechanical running part or than the complicated operations process, affected by environment little, the constraint removal of this locator is to finish by the pin rod that takes out becket bridle, this operation can be finished in the aperture, easy to operate, it can be used for directly measuring different depth rock displacement amount and installs other sensor in order to measure the multiple use of rock stratum absciss layer etc. in the hole; Its reliable operation, and simple in structure, make easily, with low cost.
Description of drawings:
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is that the A of structure chart of the present utility model is to view.
Fig. 8 is the working state figure of structure chart of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.As shown in Figures 1 and 2, it comprises connector 1, spring claw hook 2, confinement ring 3, mounting rod 4, pin rod 5, steel wire 6, pin 7, steel cable 8 etc.Connector 1 is a round tube, porose on its left end two side, pin 7 is equipped with at the middle part, its right-hand member head has the burr of a plurality of projectioies, spring claw hook 2 usefulness spring steel wires are made, there is the torsion spring of crotch at two ends, hook can be established two or more as required, spring claw hook 2 passes connector 1 two side circular hole, be connected with connector, confinement ring 3 adopts simple and easy cluster, it can be that a two ends surrounds the steel band of an axial circular hole or the rope band of other material, can make its fastening by latch 5, mounting rod 4 is to be made of the scalable socket pipe of more piece, extract earlier less pipe during use internally out, be connected and fixed with pin in per two pitch circle pipe lap-joints, mounting rod 4 is connected with the burr friction of connector 1 by projection, pin rod 5 is round bars, its right-hand member head is porose, stay cord 8 passes this hole and ties down pin rod, its left end head inserts in two stomidiums of confinement ring 3, spring claw hook 2 bindings are constrained in the two side of connector, spring claw hook 2 can also be installed in the connector 1 by the two-way combined type that waits in the left and right sides, steel wire 6 is fixed on the middle part of connector 1 by pin 7, when locator send into boring in desired location the time, take out pin rod 5 and get final product the restraint forces of removal to spring claw hook 2, spring claw hook 2 two ends are opened automatically, support is to the boring crag, hook is finished by self elastic force the steel wire on the locator is worked on the desired location in the hole, makes the locator location.
Except that fixing steel wire, the steel pipe, the bar that are connected on the connector all can be located equally; Other needs to determine at hole wall some sensors of location, position, as long as be fixed on the connector, and also can be by last method location.
