Abstract
A novel special-shaped anchor-rod tray for mine belongs to a tray matched with an anchor-rod. The two ends of the anchor-rod tray are provided with two small planes and two big planes are arranged to form an included angle between the two small planes. One of the big planes is provided with a hole and an included angel is also arranged between the big plane and the two small planes. The two small planes are in the same horizontal plane. An anchor-rod tray is provided with an included angle formed by the two big planes. When the anchor-rod body is not vertical with the surrounding of a tunnel, the inclined plane processing angle of the novel special-shaped anchor-rod tray is adjusted properly according to the different included angles between the anchor-rod body and the coal rock wall surrounding the tunnel so as to guarantee the anchor-rod can be forced uniformly in any condition. The angle of the projecting part of the anchor-rod tray can adopt the actual included angel of the coal rock surrounding the tunnel and meet the construction needs that the surrounding of the anchor-rod tray are tightly closed to the surface of the coal rock. The utility model has the advantages of high intensity, good malleability, adjustable angle, light weight, low processing and manufacturing cost, wide adaptability, etc., and protects the security of the tunnel support.
Description
Technical field
The utility model relates to a kind of and the supporting supporting plate of anchor pole, the special-shaped Supporting plate for anchor of particularly a kind of new mine product.
Background technology
Supporting plate for anchor is an important components in the bolt support system, and its performance directly influences the supporting effect of anchor pole.Selection Supporting plate for anchor principle is that the supporting capacity of supporting plate should be complementary with the anchored force of anchor pole, and should make anchor rod body, nut evenly stressed.Top board anchor metal supporting plate mainly uses the butterfly supporting plate and the plate shaped supporting plate of Q235 or the compacting of 20MnSi steel plate, and a small amount of cast iron supporting plate that uses is generally truncated cone-shaped, diameter 100～150mm, thick 8～15mm.
Driving increase along with large inclination working surface, anchor rod body and tunnel-surrounding are with regard to out of plumb, existing plane Supporting plate for anchor and common butterfly Supporting plate for anchor just can not be close to the coal petrography surrounded surface, cause the anchor pole unbalance stress, generally in the afterbody bending, easily brokenly fall, cause the whole supporting intensity in tunnel to reduce, jeopardize roadway support safety.
Summary of the invention
The purpose of this utility model is when a kind of anchor rod body and tunnel-surrounding out of plumb will be provided, and anchor pole still can the special-shaped Supporting plate for anchor of stressed uniform new mine product.
The purpose of this utility model is achieved in that two ends of this Supporting plate for anchor have two facets, two big planes that constitute angle are arranged between two facets, porose on big plane therein, between big plane and two facets angle is also arranged, two facets are on the same horizontal plane.
Beneficial effect: owing to adopt such scheme, the angle that Supporting plate for anchor has two big planes to constitute, when anchor rod body and tunnel-surrounding out of plumb, can be according to the different angle of anchor rod body with tunnel-surrounding coal petrography wall, suitably adjust the machining angle on novel special-shaped Supporting plate for anchor inclined plane, guaranteed under any circumstance, anchor rod body can become 90 ° of angles all the time with the folder degree on Supporting plate for anchor inclined plane, when anchor rod body and tunnel-surrounding out of plumb, anchor pole still can be stressed even, reached the purpose of this utility model.The angle at the protrusion position of this Supporting plate for anchor can adapt to the actual angle of tunnel-surrounding coal petrography, can satisfy Supporting plate for anchor and be close to the construction needs on coal petrography surface all around, anchor rod body under any circumstance all can become 90 ° angle with the inclined plane of special-shaped Supporting plate for anchor, make anchor rod body stressed evenly, intensity reaches designing requirement, have intensity height, good toughness, adjustable angle, in light weight, plurality of advantages such as the processing and manufacturing cost is low, compliance is extensive, guaranteed the safety of roadway support.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
The specific embodiment
Embodiment 1: two ends of this Supporting plate for anchor have two facets 1, two big planes 3 that constitute angle are arranged between two facets 1, porose 2 on big plane therein, between big plane and two facets angle is also arranged, two facets are on the same horizontal plane.
Claims (1)
1, the special-shaped Supporting plate for anchor of a kind of new mine product, it is characterized in that: two ends of this Supporting plate for anchor have two facets, two big planes that constitute angle are arranged between two facets, porose on big plane therein, between big plane and two facets angle is also arranged, two facets are on the same horizontal plane.
