Abstract
A free-expanding-type centering device is mainly applied to the detection of the construction quality of the drilling hole of a right reversed plumb hole of concrete large dam and the buried installation of the inverted plumb line in the hydraulic and hydro-power engineering. The free-expanding-type centering device mainly comprises an upper part connection section and a lower part connection section, wherein, a heavy bob is connected with the lower part connection section through a steel wire, and the upper part connection section and an adjusting element are connected with a central rod through a thread, and the lower part connection section is connected with the central rod by thread, and a spring is sleeved on the central rod, and a telescopic end hinge seat is connected with a fixed end hinge seat through a free-expanding mechanism, and telescopic arms of the free-expanding mechanism are connected with each other through a hinge, and the upper and the lower end of the telescopic arms are respectively connected with the telescopic end hinge seat and the fixed end hinge seat through two hinges, and a trolley is arranged between different groups of telescopic arms. With the centering device, the telescopic arms can extend to the appropriate position inside the hole and can extrude the spring through the telescopic end hinge seat, so that the trolley can walk just against the wall of the hole, thereby realizing the centering effect.
Description
Technical field
The utility model is a kind of equipment of measuring bore inclining degree and effective aperture, is mainly used in the drilling construction quality testing of the positive inverted vertical hole of Hydraulic and Hydro-Power Engineering concrete dam and the installation of burying underground of positive reversed pendulum.
Background technology
At present, one of main means of deformation monitoring of concrete dam adopt to be installed and to be buried vertical frontal line underground and reversed pendulum is realized.When burying vertical frontal line and reversed pendulum underground, at first will be in the boring of the dam position of design, the device that just falling to hang down is had relatively high expectations to the vertical degree of boring, the hole of being bored must be vertical, deviation requires to be controlled in 0.1%, and the quality of drilling quality directly influences the success or failure that vertical line is provided with, and it is undesirable to hole sometimes, causing punches scraps and beats again, and also causes very big economic loss.Therefore need in boring procedure, often detect the hole scattering value.Generally whenever creeping into 1～2m promptly should detect once.This detection, general adopt the buoyancy aid assembly of falling to hang down close elasticity put in device carry out.
In addition, just, in the reversed pendulum installation process, vertical line just can be arranged in order to make, the optimum position in the inverted vertical hole, performance just, the maximum utility of falling to hang down, should map according to the eccentricity value of each elevation position of holing before hanging down burying underground down, determine the burial place of vertical line.With the center, aperture is the coordinate axis initial point, the center, hole that each elevation records is demarcated according to a certain percentage on coordinate diagram, and again with same engineer's scale, be the center of circle with the center that respectively marks, be that radius is drawn circle with the corresponding radius value of holing.The common part of each circle is the useful space, and pairing least radius is called the effective aperture, can determine the optimum position that positive reversed pendulum is buried underground according to this useful space.The spring-elastic that has commonly used is at present put middle device, though the device processing and fabricating was simpler during this elasticity was put, but big defective is arranged, topmost problem is because the spring steel plate bottom only links to each other with spring, lacks constraint, after device is put into the hole in putting, as easy as rolling off a log friction, rotate and to make the spring steel plate distortion that is distorted because of spring steel plate and hole wall, even upper hinge is damaged, do not reach the effect in putting, thereby greatly reduce the accuracy of measurement.Just used similar elasticity to put middle device in the construction of Yixing, Jiangsu hydroenergy storage station inverted vertical hole in early stage, it is undesirable to facts have proved that this elasticity is put middle device measurement effect, and is easier in the work progress damage.
Summary of the invention
The purpose of this utility model is will provide a kind of and be easy to process, can reach the order of measuring all size aperture measure of skewness and effective aperture according to the big freedom in minor affairs design parts in tested aperture, and the free expanding that workable, measurement effect is good is put middle device.
The purpose of this utility model is achieved in that a kind of free expanding puts middle device, comprise the top linkage section, the bottom linkage section, weight is connected with the bottom linkage section by wire rope, the top linkage section is connected with center-pole by screw thread with regulating part, the bottom linkage section adopts with center-pole and is threaded, spring housing is contained on the center-pole, be connected by free expanding mechanism between flexible end free bearing and the stiff end free bearing, be connected through the hinge between the telescopic arm of free expanding mechanism, telescopic arm two ends up and down passes through two hinges and is connected with the stiff end free bearing with flexible end free bearing respectively, and each is organized roller is set between the telescopic arm.Stiff end free bearing and center-pole are fixed by latch.
The free expanding that the utility model provides is put middle device, can make telescopic arm be retractable to suitable position in the hole and the end free bearing extrusion spring that passes through to stretch, and makes roller be close to the hole wall walking just, thereby reaches the effect in putting.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, device comprised top linkage section 1 during free expanding was put, bottom linkage section 11, weight 13 is connected with bottom linkage section 11 by wire rope 12, top linkage section 1 is connected with center-pole 3 by screw thread with regulating part 2, bottom linkage section 11 adopts with center-pole 3 and is threaded, spring 4 is sleeved on the center-pole 3, be connected by free expanding mechanism between flexible end free bearing 5 and the stiff end free bearing 10, free expanding mechanism mainly is made of telescopic arm 7 and roller 8, connect by hinge 9 between the telescopic arm 7 of free expanding mechanism, telescopic arm passes through two hinges 6 in two ends about in the of 7,14 be connected with stiff end free bearing 10 with flexible end free bearing 5 respectively, each is organized roller 8 is set between the telescopic arm 7.Stiff end free bearing 10 and center-pole 3 are fixed by latch.
Before the use, earlier free expanding mechanism is installed, on center-pole 3, flexible end free bearing 5 internal key teeth snap in center-pole 3 keyways with free expanding mechanism integral installation, and stiff end free bearing 10 is fixed with center-pole 3 usefulness pins.Spring 4 is enclosed within on the center-pole, top linkage section 1, regulating part 2 are threaded with center-pole 3 again, and bottom linkage section 11 also is threaded with center-pole 3, at last weight 13 usefulness wire rope 12 are tied up on the bottom linkage section 11.
During use, free expanding is put middle device be connected with the buoyancy aid group of hanging down, and free expanding is put middle device slowly put into the hole from the aperture, the telescopic arm 7 of free expanding mechanism is along with the decline of device in putting is shunk gradually, and end free bearing 5 extrusion springs that pass through to stretch.When roller 8 drops to the hole elevation, begin to be close to the hole wall walking immediately.When roller 8 when hole wall runs to the elevation that the hole domestic demand measures, measure the deviation value at wire rope and center, aperture with little steel ruler, just can obtain the effective range in hole gradient and this hole.
