Abstract

The utility model discloses a kind of FLOOR ANCHOR band angle mounting devices, it is made of bevel edge steel plate, vertical steel plate and bottom surface steel plate three parts, the end of the bevel edge steel plate, vertical steel plate and bottom surface steel plate joins end to end, the section that it is surrounded is at right angles triangular shaped, and bevel edge steel plate center offers the bevel edge through-hole and vertical plane through-hole for matching bolt diameter with vertical steel plate corresponding position respectively.The utility model structure is simple, easy to use, precisely can construct and install band angle FLOOR ANCHOR, while can substantially reduce anchor rod pallet board and coal and rock interface pressure.

Description

A kind of FLOOR ANCHOR band angle mounting device

Technical field

The utility model relates to a kind of tunnel or tunnel support installation equipment more particularly to a kind of FLOOR ANCHOR band angle to pacify Assembling device.

Background technique

When carrying out the underground engineering constructions such as mine and tunnel, the excavation of underground passage can enable country rock generate deformation to Free space release, with the continuous increase of mining depth, supporting is given to roadway surrounding rock with guarantee underground engineering it is smooth into Row is extremely important.In underground engineering in common support apparatus, suspension roof support reaches 80% or more, is most common and most important Support pattern, therefore the construction quality of anchor pole is related to the supporting effect of entire engineering, but in certain particular locations, such as in Da Xiang When road FLOOR ANCHOR, the construction angle of anchor pole can only be estimation installation, it is difficult to ensure that the construction angle of FLOOR ANCHOR, to cause FLOOR ANCHOR setting angle inaccuracy；Furthermore mounted anchor pole, outer end generally use nut tightening to cover on anchor pole Pallet contacts pallet with coal and rock and carrys out fixing anchor bar, and such pressure acts directly on pallet and coal petrography contact level, this is very It is easy to keep contact surface destruction imperfect, both the above situation finally all can cause Effects of Supporting that desirable, shadow is not achieved Ring tunnel safety stability.

Summary of the invention

The utility model provides a kind of FLOOR ANCHOR band angle mounting device, to solve in existing FLOOR ANCHOR work progress Setting angle is not accurate and anchor rod pallet board is with coal petrography contact level is caused coal petrography contact level to be easy to destroy by compared with power concentration Technical problem.

To achieve the above object, a kind of FLOOR ANCHOR band angle mounting device provided by the utility model, including bevel edge steel The end of plate, vertical steel plate and bottom surface steel plate, the bevel edge steel plate, vertical steel plate and bottom surface steel plate joins end to end, and surrounds Section is at right angles triangular shaped, and bevel edge steel plate center offers and bolt diameter phase respectively with vertical steel plate corresponding position Matched bevel edge through-hole and vertical plane through-hole can reach FLOOR ANCHOR when FLOOR ANCHOR passes through the bevel edge through-hole and vertical plane through-hole Setting angle requirement.

Connection is welded and fixed in the end head and the tail of the bevel edge steel plate, vertical steel plate and bottom surface steel plate.

The bevel edge through-hole and vertical plane through hole center line and face where the bottom surface steel plate are in a certain angle, when base angle anchor Bar can reach FLOOR ANCHOR setting angle requirement when passing through the device hole.

Compared with prior art, the utility model has the following beneficial effects:

It is welded firstly, the present apparatus only has three blocks of steel plates, it is economical simple and durable；Secondly, the present apparatus can be by adjusting in advance Relationship between whole three pieces of steel plate lengths is come FLOOR ANCHOR setting angle accurate problem when realizing tunnel design and construction；Finally, The present apparatus uses most stable of three-legged structure, can effectively ensure that the stability of the present apparatus, while by anchor rod pallet board and coal Rock mass contact becomes anchor rod pallet board and contacts with steel plate, can effectively avoid the destruction between coal petrography contact level, and will be on contact surface Pressure resolve into vertical and horizontal side and upward pressure, this will greatly reduce the pressure on the device and tunnel coal petrography contact level Power is capable of the complete of effective protection contact surface.In short, the utility model structure is simple, and it is practical and convenient, can not only have well Effect, which solves the problems, such as that FLOOR ANCHOR setting angle is accurate, also can solve anchor rod pallet board and coal petrography contact level stress friendship concentration problem.

Detailed description of the invention

Attached drawing is only used for showing the purpose of specific embodiment, and is not considered as limitations of the present invention.

Fig. 1 is that the FLOOR ANCHOR band angle mounting device of the utility model cooperates schematic diagram.

Fig. 2 is the FLOOR ANCHOR band angle mounting device three-view diagram of the utility model.

In figure, 1- bevel edge steel plate, the vertical steel plate of 2-, the bottom surface 3- steel plate, 4-1- bevel edge through-hole, 4-2- vertical plane through-hole, 5- anchor Bar, 6- pallet, 7- nut.

Specific embodiment

Further explanation is made to the utility model with reference to the accompanying drawing, the utility model embodiment includes but is not limited to The following example.

As shown in Fig. 1 to 2, this reality embodiment provides a kind of FLOOR ANCHOR band angle mounting device, including bevel edge steel plate 1, vertical steel plate 2 and bottom surface steel plate 3, first according to FLOOR ANCHOR construct angle requirement, determine bevel edge steel plate 1, vertical steel plate 2 and The length dimension of bottom surface steel plate 3, three's size meet Pythagorean theorem, are welded to form right-angle triangle；Then it is welding Connect completion 1 center of triangular arrangement bevel edge steel plate and vertical 2 corresponding position of steel plate, process circle respectively using perforating device Bevel edge through-hole 4-1 and vertical plane through-hole 4-2 makes the bevel edge through-hole 4-1 and the vertical plane through-hole 4-2 line of centres and the bottom surface steel plate 3 places face are in a certain angle；Then, this mounting device is placed on construction tunnel base angle position, the drilling rod of jumbolter is worn The bevel edge through-hole 4-1 and vertical plane through-hole 4-2 are crossed, jumbolter is started and carries out inclined drill construction；Finally, by Anchor Agent and anchor Bar 5 is inserted into the inclined drill constructed, and fastens FLOOR ANCHOR 5 with pallet 6 and nut 7 after stirring.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in Change or replacement, should be covered within the scope of the utility model.
