Description
Technical field
The utility model relates to a kind of displacement monitor, is specifically related to a kind of displacement monitor of extensible energy-absorbing anchor.
Background technology
After roadway excavation, country rock produces distortion, and top board occurs sinking, and through initial support, secondary supporting or even repeatedly after supporting, surrouding rock deformation tends towards stability eventually.In order to the data obtaining the amount of crushing, side displacement, two helps the reflection stability of surrounding rock such as the amount of shifting near and supporting effect, conventional monitoring instrument has: convergence gauge, roof separation indicator, multipoint displacement meter etc.For within surface, tunnel and even the displacement monitoring in deep, general roof separation indicator or the multipoint displacement meter of adopting is measured.Although these monitoring instruments such as roof separation indicator, multipoint displacement meter existing are day by day advanced now, the general character deficiency that they still also exist complex structure, install difficulty and can not be combined with common bolt.
Summary of the invention
In order to solve the problems referred to above that existing displacement monitor exists, the displacement monitor of the extensible energy-absorbing anchor that the utility model provides a kind of structure simple, easy to use.
The technical scheme that the utility model adopts is as follows: comprise slippage attachment cap, monitor fixed cover, intermediate connector, displacement data monitor disk and rubber washer, described slippage attachment cap is sleeved on anchor end, monitor fixed cover is fixed on the sleeve of anchor, one end of intermediate connector loads in monitor fixed cover fixing, displacement data monitor disk is made up of link and monitor disk, link is the external thread link of hollow, link is bolted on intermediate connector, the center, termination of slippage attachment cap is provided with tape measure abutment ring, the center of monitor disk is provided with scroll spring, scroll spring is provided with tape measure, the circumferential edge of monitor disk is provided with angle sheave, the excircle of monitor disk is provided with reading window, tape measure is connected to slippage attachment cap termination tape measure abutment ring through the angle sheave of monitor disk circumferential edge.
In the displacement monitor of above-mentioned extensible energy-absorbing anchor, also comprise rubber washer, between intermediate connector and monitor fixed cover, be provided with rubber washer.
In the displacement monitor of above-mentioned extensible energy-absorbing anchor, be provided with limited location snap ring between two angle sheaves be connected with tape measure abutment ring, tape measure abutment ring is provided with fastening snap ring.
In the displacement monitor of above-mentioned extensible energy-absorbing anchor, monitor disk is discoid box hat structure.
The beneficial effects of the utility model are: the utility model can support the use with extensible energy-absorbing anchor, in the position needing to carry out monitoring, this anchor pole displacement monitor installed by extensible energy-absorbing anchor, can according to monitoring location need give full play to its monitoring dirigibility; This anchor pole displacement monitor is matching used with extensible energy-absorbing anchor, therefore just eliminates as complicated procedures of forming such as monitor drilling, installations, and uses easily.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model.
Explanation in accompanying drawing: 1---slippage attachment cap, 2---monitor fixed cover, 3---intermediate connector, 4---displacement data monitor disk, 5---reading window, 6---rubber washer, 7---tape measure abutment ring, 8---angle sheave, 9---fastening snap ring, 10---limited location snap ring, 11---tape measure, 12---scroll spring, 13---extensible energy-absorbing anchor anchor pole, 14---extensible energy-absorbing anchor fastening part sleeve, 15---extensible energy-absorbing anchor anchor pole male portion, 16---extensible energy-absorbing anchor pallet.
Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
As shown in Figure 1, the utility model comprises slippage attachment cap 1, monitor fixed cover 2, intermediate connector 3, displacement data monitor disk 4 and rubber washer 6.Described slippage attachment cap 1 is sleeved on anchor anchor pole 13 end, monitor fixed cover 2 is fixed on the sleeve 14 of anchor, one end of intermediate connector 3 loads in monitor fixed cover 2 fixing, displacement data monitor disk 4 is made up of link and monitor disk, link is the external thread link of hollow, link is bolted on intermediate connector 3, the center, termination of slippage attachment cap 1 is provided with tape measure abutment ring 7, the center of monitor disk 4 is provided with scroll spring 12, scroll spring 12 is provided with tape measure 11, the circumferential edge of monitor disk 4 is provided with angle sheave 8, the excircle of monitor disk 4 is provided with reading window 5, tape measure 11 is connected to slippage attachment cap termination tape measure abutment ring 7 through the angle sheave 10 of monitor disk circumferential edge.
Assemble method of the present utility model: see Fig. 1, first, loads intermediate connector 3 in monitor fixed cover 2; Then, displacement data monitor disk 4 is screwed in intermediate connector 3; Secondly, because the tape measure 11 of displacement data monitor disk 4 inside can limit tape measure automatic retraction under there is the stop of limited location snap ring 10(limited location snap ring at angle sheave at angle sheave 8 place, aperture), tape measure 11 has one section of excess length; Then, the section more than needed of tape measure 11 is fixed on by fastening snap ring 9 in the tape measure abutment ring 7 of slippage attachment cap 1 end; Finally, loaded in intermediate connector 3 by the hexagonal structure end of slippage attachment cap 1, namely the assembling of whole anchor pole displacement monitor completes.
During supporting, after country rock produces distortion, shank portion 13 and the sleeve part 14 of extensible energy-absorbing anchor can produce relative displacement, and the body of rod 13 can drive slippage attachment cap 1 to move in the process; So slippage attachment cap 1 pulls tape measure 11, tape measure 11 can produce variation at the reading window place of displacement data monitor disk 4; Read now reading window scale value; By with record reading value before and subtract each other, anchor pole displacement herein during just can drawing supporting.
