The technical field is as follows:

the utility model belongs to the technical field of mine collecting space area is surveyed, what mainly relate to is a portable collecting space area surveys protector.

Background art:

a certain large-scale open-pit mine in China belongs to an underground mining to open-pit mine, a plurality of underground goafs exist at the lower part of an open-pit mine, in order to ensure the safety of open mining operation, the shape, the size, the distribution position and the like of the goafs at the lower part of the mine need to be detected in advance, and the scheme of firstly drilling advanced detection and then three-dimensional laser scanning accurate detection is adopted for goaf detection in the prior mine.

When the three-dimensional laser scanning is used for detecting the empty area, a laser probe of the three-dimensional laser detector is required to be put down to the empty area along a drilling hole for scanning, and finally, a three-dimensional figure of the empty area is formed. Because there is thick virtual slag blanket at the position of the big drill way, if the rubble falls into downthehole easily to lead to the laser probe to be blocked and can't take out during the scanning to the instrument that makes the value very not very is scrapped, also can greatly reduced scanning personnel's work efficiency simultaneously, leads to the time overlength of staff's work in the dead zone top, and factor of safety reduces.

The utility model has the following contents:

in order to overcome the defects, the utility model provides a portable dead zone detection protective device.

The utility model provides a technical scheme that its technical problem adopted:

a portable dead zone detection and protection device comprises

A sleeve;

the blocking stone plate is positioned on the lower surface of the pedal plate;

wherein, the sleeve is placed in a drill hole, the pedal is placed on the broken stone at the opening, and the stone blocking plate is embedded in the broken stone at the opening.

The stone blocking plates comprise a second stone blocking plate which is positioned at the end part of the pedal and is L-shaped and a second stone blocking plate which is positioned between the first stone blocking plate and the drill hole and is T-shaped.

The pedal comprises a left pedal and a right pedal, and the left pedal and the right pedal are connected with the outer wall of the sleeve through hinges.

Due to the adoption of the technical scheme, the utility model discloses have following superiority:

the utility model provides a portable dead zone detection protector, which can effectively prevent the broken stone at the orifice from falling into the hole when the dead zone is scanned, thereby greatly reducing the probability of scrapping of valuable instruments caused by the locking of the laser drill bit by the broken stone; the working efficiency of scanning the empty area can be greatly improved; meanwhile, the working time of scanning personnel in the empty area above the empty area is reduced, and the safety factor is improved.

The specific implementation mode is as follows:

the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that, if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the position or positional relationship based on the position or positional relationship shown in the drawings, or the position or positional relationship which is usually placed when the product of the present invention is used, the description is only for convenience of description and simplification, but the indication or suggestion that the device or element to be referred must have a specific position, be constructed and operated in a specific position, and thus, cannot be understood as a limitation of the present invention. Furthermore, the appearances of the terms "first," "second," and the like in the description of the present invention are not intended to be limiting but rather are to be construed as indicating or implying relative importance.

Furthermore, the terms "horizontal", "vertical" and the like when used in the description of the present invention do not require that the components be absolutely horizontal or hanging, but may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

The portable dead zone detection and protection device comprises

The sleeve 1, preferably the sleeve 1 is cylindrical in steel, and since the bore 9 is circular in cross-section, the sleeve 1 is cylindrical and is conveniently located in the bore 9.

The foot pedal is positioned at the top end of the sleeve 1, preferably, the foot pedal is made of steel materials and can be round or rectangular.

The stone blocking plate is positioned on the lower surface of the pedal plate and can be inserted into the orifice broken stone 10 at the periphery of the drilled hole 9 to stabilize the orifice broken stone 10 so that the orifice broken stone does not fall into the drilled hole 9 and further protect the laser drill bit;

during exploration, the sleeve 1 is placed in the drill hole 9, the pedal plate is placed on the hole broken stone 10, feet step on the pedal plate, the stone blocking plate is embedded into the hole broken stone 10 under the action of gravity, and after the stone blocking plate is completely embedded into the broken stone, the broken stone is extruded under the stress, so that the stone blocking plate is more stable, and the probability that the broken stone falls into the drill hole 9 is greatly reduced.

Preferably, the stone blocking plates comprise a second stone blocking plate 5 which is positioned at the end part of the pedal plate and is L-shaped and a second stone blocking plate 4 which is positioned between the first stone blocking plate and the drill hole and is T-shaped, the second stone blocking plate 5 is L-shaped and positioned at the end part of the pedal plate, after the broken stones are embedded, on one hand, the end part of the pedal plate can be stabilized, on the other hand, the broken stones at the position can be extruded in the direction, close to the drill hole 9, of the inner side of the pedal plate, and the T-shaped second stone blocking plate 4 can block the extrusion of the broken stones, so that the second stone blocking plate 4 and the second stone blocking plate 5 can not only stabilize the broken stones 10 at the hole, but also can prevent the pedal plate from moving after the broken stones are embedded.

Preferably, the second stone blocking plate 4 is arranged close to the drill hole 9, so as to reduce the range of movable stones around the drill hole 9, and the stones are stabilized when the pedal plate is completely stabilized.

Preferably, as shown in fig. 2, the pedal includes a left pedal 3 and a right pedal 2, the left pedal 3 and the right pedal 2 are both connected to the outer wall of the sleeve 1 through hinges 6, if the pedals are made of steel plates with a single structure, the pedal is large in size and inconvenient to carry, so that the pedals can be divided into two parts, the left pedal 3 and the right pedal 2 are connected to the sleeve 1 through the hinges 6, when the pedal is used, the two pedals 3 are unfolded, the folding lines are used as central axes, the pedals are laid on the orifice gravel 10, and after the pedal is used, the pedals can be folded to facilitate carrying.
