Abstract
The utility model discloses a kind of underground vertical hole hole depth survey tool, including measurement rope, weight and locating part, measurement rope twines the single piece of woollen goods rope for steel wire rope outside, weight is connected to the lower end of measurement rope, locating part is to have certain degree of hardness, length to be more than the flexible plastic tube in blasthole aperture, for locating part at the nearly weight on measurement rope, measurement rope pinions the length direction middle position of locating part, ensures that locating part is not fallen out in use.Weight traction measurement rope is passed through from blasthole, and when measurement rope is put into from aperture, locating part is pulled to vertical state, makes its downlink that can restrict with measurement.When weight is pierced by from blasthole, and locating part is also pierced by from blasthole, locating part recovers to horizontality.After operator feels that locating part is pierced by from the lower end of blasthole, measurement rope is up carried, you can locating part is stuck at the lower end aperture of blasthole, the hole depth that can thus measure blasthole is the distance between locating part and blasthole aperture.
Description
Technical field
It the utility model is related to a kind of dimensional measuring instrument, and in particular to a kind of underground vertical hole hole depth survey tool.
Background technology
For a long time, due to the limitation of live objective condition, vertical hole in mine engineering explosion（Medium-length hole）Hole depth one
Directly can not accurately it measure, can only be by estimating run of steel and drilling rod quantity or by soft bamboo（Series connection）Measurement obtains hole indirectly
It is deep, but no matter hole depth determined using a kind of that mode, error is all larger, is unfavorable for the control of blast hole hole depth, to ensuing blast
Powder charge and demolition effect will all adversely affect.After blasthole has been constructed at the same time, due to geological structure, joint fissure, explosion shake
The factor such as dynamic influences, and the blasthole hole depth moment is among change.For avoid blast hole hole depth it is improper demolition effect is caused it is unfavorable
Influence, a kind of simple and practical, convenient and reliable survey tool should be invented accurately to grasp blasthole hole depth.The utility model structure
Simply, processing is simple, is widely used, is easy to use, can solve the problems, such as the measurement of bursting work borehole blasting hole hole depth, quick-fried to improve
Broken effect.
Utility model content
The purpose of this utility model is to provide a kind of instrument that can accurately measure blasthole hole depth.
This underground vertical hole hole depth survey tool provided by the utility model, including measurement rope, weight and spacing
Part, measurement rope is twines the single piece of woollen goods rope outside steel wire rope, weight is connected to the lower end of measurement rope, and locating part is certain hard to have
Degree, length are more than the flexible plastic tube in blasthole aperture, and locating part at the nearly weight on measurement rope, restrict the length of locating part by measurement
Degree direction middle position is pinioned.
The outer designation card being fixed with for measurement unit length of measurement rope.
The upper end of the measurement rope is connected with draw ring.
The designation card is made of aluminium, can be fixed on by pressure clamp on the measurement rope.
The device further includes auxiliary rope, the lower end of auxiliary rope is connected to the end of the locating part, upper end be connected to it is described
On draw ring.
The utility model makes measurement rope be passed through from blasthole by the traction of weight, and measurement rope is put into from the aperture of blasthole
When, the locating part measured on rope is pulled to vertical state, enables locating part with measurement rope downlink.When weight is pierced by from blasthole
Into in bottom chamber or tunnel, when locating part is also pierced by from blasthole, locating part is in free state at this time, so water can be in
Level state.Since the length of locating part is more than the aperture of blasthole, so when operator feels that locating part is worn from the lower end of blasthole
After going out, measurement rope is up carried, you can locating part is stuck at the lower end aperture of blasthole, can thus measure the hole of blasthole
Depth is the distance between locating part and top chamber.In order to further ensure locating part can be passed through smoothly from blasthole and instrument
Recycling, set an auxiliary rope being connected to by locating part end.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model one embodiment.
Embodiment
As shown in Figure 1, this underground vertical hole hole depth survey tool disclosed in the present embodiment, including it is measurement rope 1, spacing
Part 2, weight 3, auxiliary rope 4, designation card 5.
Measurement rope 1 is fixed with the sign for measurement unit length to twine the single piece of woollen goods rope outside steel wire outside measurement rope 1
Card 5.Weight 3 is connected to the lower end of measurement rope 1, and the upper end of measurement rope 1 is connected with draw ring.
The length direction centre position of locating part 2 is connected as a single entity with measurement rope 1.
Designation card 5 is made of aluminium, can be fixed on by pressure clamp on measurement rope 1.
The lower end of auxiliary rope 4 is connected to the close end of locating part 2, upper end is connected on the draw ring of 1 upper end of measurement rope.
The locating part of the present embodiment is restricted its length direction middle position using the flexible plastic tube for having certain degree of hardness, measurement
Pinion, ensure that locating part is not fallen out in use.The length of locating part is about bigger 100mm than the aperture of blasthole.Weight weight
Whole instrument is subject in the selection of amount can pass through blasthole.
For this instrument in use, locating part is artificially first pulled to vertical state at aperture, the traction for then passing through weight will
Measurement rope is slowly transferred, until feel that weight and locating part are all pierced by into bottom chamber or tunnel from the lower end of blasthole,
Then up carried after measurement rope is transferred a little again, ensure that locating part is horizontal and block the lower end aperture of blasthole, at this time
Make marks at the top of measurement rope is corresponding at chamber, the length between the mark and locating part is the depth of the blasthole, by instrument
The number of number designation card is that may know that the depth of blasthole after withdrawal.Finally measurement is restricted toward decentralization a bit again, is up pulled auxiliary
Rope is helped, locating part is in vertical state, measurement rope and auxiliary rope is then recycled at the same time, instrument is withdrawn.
