Description

TECHNICAL FIELD

[0001] The utility model relates to tunnel anchor rod support technical field, concretely relates to a kind of anchoring agent stop device. BACKGROUND

[0002] In surrounding rock support engineering construction, it needs to use anchor rod to stabilize and reinforce surrounding rock, and in the prior art, when anchoring construction is carried out on a tunnel, a hole is first arranged according to construction drawings, then a drill hole device is used to drill an anchor rod hole in the surrounding rock at the hole arrangement position, and then an anchoring agent is pushed into the working hole and is blocked.The anchor rod installation device is used to install the hollow anchor rod in the anchor rod hole, and finally the handheld pistol drill is used to rotate the anchor rod nut to stir the anchor rod, so that the anchoring agent at the bottom of the hole is mixed with AB glue to be coagulated, and after waiting for 30 seconds, the handheld pistol drill is used to tighten the anchor rod nut to fix the tray.

[0003] In the actual construction process in the tunnel, in order to facilitate the installation of the anchor rod, the diameter of the anchor rod hole drilled in the design and construction is usually greater than the diameter of the anchor rod and the diameter of the anchoring agent, so that the anchoring agent is easy to slip off when being injected, which affects the overall quality of the anchoring construction.

[0004] In order to prevent the anchoring agent from slipping off when being injected, the anchoring agent tail end is generally sleeved with a stop device, for example, a push-resistance type fixing device for anchoring agent disclosed in CN204663556U, which comprises a hollow cap-shaped sleeve cap for sleeving one end of the anchoring agent bag body, and a plurality of elastic contraction fins are inclinedly extended outward at the outer end of the sleeve cap and have tension, so that the anchoring agent cannot be returned after being injected.However, the arrangement of the elastic contraction fins can ensure that the anchoring agent expels excess air when entering the working hole, but it cannot ensure sufficient flight speed when the anchoring agent is shot from the air injection pipe due to insufficient windward area. UTILITY MODEL CONTENTS

[0005] The utility model aims at solving the problem that the existing anchoring agent stop device cannot ensure sufficient flight speed while meeting the requirement of expelling excess air when the anchoring agent enters the working hole.

[0006] The technical scheme provided by the utility model is as follows: an anchoring agent stop device, comprising:

[0009] A pneumatic ring is arranged on the outer surface of the cover-shaped body, and the pneumatic ring is located on the side of the elastic supporting sheet facing the bottom of the cover-shaped body.

[0010] The elastic supporting sheet of each layer is arranged with a plurality of pieces and is distributed along the circumference of the cover-shaped body, so that the gap between the elastic supporting sheets can discharge excess air when the anchoring agent enters the working hole; the pneumatic ring near the bottom increases the windward area and improves the energy accumulated by the anchoring agent from the compressed air jet pipe, thereby improving the initial flight speed.

[0011] As a preferred, the outer diameter of the free end of the elastic supporting sheet of each layer is greater than the outer diameter of the pneumatic ring, which avoids the influence of the pneumatic ring on the discharge of excess air when the anchoring agent enters the working hole.

[0012] As a preferred, the inner ring of the pneumatic ring is connected to the outer surface of the cover-shaped body, and the outer ring is inclined toward the bottom of the cover-shaped body, which improves the strength of the pneumatic ring.

[0013] As a preferred, the outer diameter of the free end of the elastic supporting sheet located at the upper part is greater than the outer diameter of the free end of the elastic supporting sheet located at the lower part.

[0014] As a preferred, the adjacent elastic supporting sheets of the same layer are connected by an arc-shaped transition, so that an arc-shaped gap is formed between the adjacent elastic supporting sheets. The arc-shaped gap is used as a gap to discharge excess air when the anchoring agent enters the working hole, and also plays a role in improving the strength of the elastic supporting sheet.

[0015] As a preferred, the elastic supporting sheets of adjacent layers are staggered in the vertical direction, which increases the windward area without affecting the discharge of excess air, improves the energy accumulated by the anchoring agent from the compressed air jet pipe, and thereby improves the initial flight speed.

[0016] As a preferred, the inner surface of the cover-shaped body is provided with at least one elastic supporting ring, the outer ring of the elastic supporting ring is connected to the inner surface of the cover-shaped body, and the inner ring is inclined toward the bottom of the cover-shaped body. The structure of the elastic supporting ring similar to a reversed hook prevents the anchoring agent from being separated and discharged during the launching process.

[0017] As a preferred, a plurality of through holes are uniformly distributed on the side wall of the cover-shaped body, and the through holes are used to allow the anchoring agent to flow out of the cover-shaped body during the process of stirring the anchor rod, so as to prevent the amount of anchoring agent around the cover-shaped body at the bottom of the hole from being too small to affect the anchoring effect of the anchor rod.

[0018] As preferred, a plurality of through holes are evenly distributed on the sidewall of the cover-shaped body, and at least one circle of the through holes is arranged between the elastic supporting ring closest to the bottom of the cover-shaped body and the bottom of the cover-shaped body, so that the amount of anchoring agent between the cover-shaped body and the anchor rod is increased, and the anchoring effect of the anchor rod is improved.
