The utility model discloses on one side the interior external screw thread through ABS pipe pursues the festival and links together it by constructor, good ABS pipe will be connected on one side and drilling will be put into, when unable continuation is shen ru drilld, with last section do not have the ABS pipe of scale to replace into the scaled ABS pipe of pipe wall, and mark down the current ABS pipe number of putting into the no scale of drilling, then read the scaled ABS pipe's of outer wall reading and mark down, the two summation is drilling depth's exact value promptly. The utility model discloses simple structure, spry and light facility, excellent in use effect, labour saving and time saving, convenient to popularize and use.
Description
Technical field
This utility model relates to the device of a kind of mine destressing borehole depth survey.
Background technology
At present, in the coal mining containing gas, bump always threatens the major safety problems that colliery normally produces, and existing solution is boring pressure releasing method.The i.e. specific location area at rib is holed, and to change coal body bearing capacity, makes stress concentration degree decline, and makes stress in coal bed peak value shift to coal and rock deep, increases resistance, reduces shock hazard or induction impact.And during bore operation, due to aspects such as operation and management, there is not up to projected depth in drilling depth.Therefore measuring drilling depth is a requisite link, but during current domestic underground work, after construction drill jewel hole, workmen is to be put into together with cord in boring by anchor cable when measuring destressing borehole, owing to every section of anchor cable limited length needs each section of anchor cable of not connection breaking, until anchor cable reaches foot of hole, when going deep into, the anchor cable connected is pulled out the length measuring cord again with tape measure, the method is due to the reason of anchorage cable materials self, quality is big, it is difficult to the factors such as connection, when carrying out drilling depth and measuring, operation is relatively complicated, waste time and energy, add the time put into when measuring drilling depth, labour force and Financial cost.
Utility model content
This utility model is aiming at above-mentioned technical problem, provide a kind of mine destressing borehole depth measurement device, simple in construction, the operant skill of operator is required relatively low, meet industry standard requirement, the drilling depth situation being suitable under different condition, it is therefore an objective to reduce labour force and the time measuring drilling depth.
For reaching above-mentioned purpose, the technical scheme that this utility model is used is: a kind of device measuring drilling depth, and including bolt, tube wall, nut and scale, described outer wall does not has graduated engineering plastics pipe and the graduated engineering plastics pipe of outer wall to be PVC material.
There is the bolt of protrusion described tube wall one end, it is carved with external screw thread, and the other end has the nut fallen in, and is carved with female thread in it, and two kinds of screw threads are 3.0cm.
The external diameter of the bolt of described tube wall one end is equal with the internal diameter of the nut on the tube wall other end, and several engineering plastics pipes are coupled together by the internal and external threads of the screw bolt and nut on tube wall.
Described tube wall is 0 scale in the nut side fallen in, and then scale increases successively to the other end, and engraving unit in even tube wall is mm, the scale of a length of 1m.
Described tube wall external diameter 3.0cm, internal diameter 2.2cm, thickness of pipe wall about 0.8cm.
This utility model simple in construction, design ingenious, when after construction drill jewel hole, workmen is while connecting section by section together by the internal and external threads of engineering plastics pipe, while the engineering plastics pipe connected is put into boring, when boring cannot be continued deeper into, the graduated engineering plastics pipe that do not has of final stage is replaced to the graduated engineering plastics pipe of tube wall, and write down the engineering plastics pipe number without scale currently putting into boring, then reading the reading of the graduated engineering plastics pipe of outer wall and write down, the two is added the exact value being drilling depth.
Owing to have employed technique scheme, having the beneficial effect that acquired by this utility model.
1, after construction drill jewel hole, by workmen while being connected section by section together by the internal and external threads of engineering plastics pipe, directly the engineering plastics pipe connected is put into boring on one side, no longer connect anchor cable section by section with iron wire, it is to avoid personnel connect the tedious work of anchor cable section by section, be greatly saved the time measuring drilling depth, the operant skill of operator is required relatively low, the drilling rod stopping state being suitable under different condition, using effect is good, time saving and energy saving.
2, in terms of safe handling, when measuring drilling depth, it is lighter that this device is compared to anchor pole, will not work the mischief personnel, can effectively reduce the labor intensity of workman, improves the labor efficiency of workman, and the safety of measurement is preferable.
3, this utility model simple in construction, cost of manufacture is low, convenient and swift, can measure the degree of depth of each boring accurately, and avoid the measuring error that anthropic factor causes, and overcomes many drawbacks, easily implements, it is simple to promote the use of.

Description of reference numerals: 1 bolt, 2 tube walls (engineering plastics), 3 nuts, 4 scales.
Detailed description of the invention
With specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings: as Figure 1-3 for a specific embodiment of the present utility model, the device of this measurement drilling depth, including bolt 1, tube wall 2, nut 3 and scale 4, described outer wall does not has graduated engineering plastics pipe and the graduated engineering plastics pipe of outer wall to be PVC material.
In technique scheme, there is the bolt 1 of protrusion described tube wall 2 one end, it is carved with external screw thread, and the other end has the nut 3 fallen in, and is carved with female thread in it, and two kinds of screw threads are 3.0cm.
In technique scheme, the external diameter of the bolt 1 of described tube wall 2 one end is equal with the internal diameter of the nut 3 on tube wall 2 other end, and several engineering plastics pipes are coupled together by the internal and external threads of the bolt 1 on tube wall 2 and nut 3.
In technique scheme, described tube wall 2 is 0 scale in nut 3 side fallen in, and then scale increases successively to the other end, and uniformly engraving unit at tube wall 2 is cm, the scale of a length of 1m.
In technique scheme, described tube wall 2 external diameter 3cm, internal diameter 2.2cm, tube wall 2 thickness about 0.8cm.
Along with deepening continuously of engineering plastics pipe, engineering plastics pipe connects by root, when several or tens engineering plastics pipes connected together are deep into and come directly towards most, can accurately measure the degree of depth of boring, the time measuring boring is greatly shortened, convenient to operation, it is applicable to different geological conditions and gas contains situation, time saving and energy saving, mixed economy cost puts into low, effective.
The part do not addressed in this utility model uses or uses for reference prior art and can realize.
The above; it is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by this utility model; amendment or supplementary or that employing the is similar mode that can readily occur in substitute, and all should contain within protection domain of the present utility model.This utility model is applicable not only to the measurement of the coal mine drilling degree of depth, additionally it is possible to for the work progress similar with colliery technique, it is provided that the measurement apparatus of a conveniently drilling rod degree of depth.
