Description

Technical Field

[0001] The utility model belongs to the technical field of mining, and relates to a mine cement traverse point. Background Art

[0002] Traverse point: A series of points are selected on the ground and connected into a broken line. The lengths of each broken line side and the turning angles are measured in sequence. This line is the traverse, and these points are the traverse points.

[0003] The traverse points should be selected in places where the roof of the underground roadway is stable, there is mutual visibility, and it is easy to install instruments for observation.

[0004] The existing setting method of the traverse point is as follows Figure 1 As shown, a hand-held drill is used to drill a hole in the roof rock, a wooden wedge (2) is driven in, and then a hook (3) is set as a fixed traverse point. However, the problems are: 1. It is very inconvenient for the operator during the drilling process in the roof rock (1); 2. The measurement points are unstable, easy to loosen, and the measurement error is large; 3. The wooden wedge is easy to fall off after a long time.

[0005] Some devices have also been designed in the prior art to assist in drilling and driving in wooden wedges. For example, a mine traverse point automatic installation device in CN 110695911A includes a long rod, a mechanical box, a box body, a slide rail, a slider, etc.; a mechanical box is arranged on the long rod, and a box body is arranged on the top of the mechanical box. It achieves the effect of being operable by a single person and convenient for installation. At the same time, by pushing the push rod upward, the electric drill drives the screw to be installed on the roof of the underground roadway. After the installation is completed, the staff pulls the push rod downward, and the push rod drives the fixed sleeve and the electric drill to move downward. When the fixed sleeve contacts the fixed top sleeve, the clamping ball is clamped into the clamping sleeve, and the mounting plate moves to the right until the new nail sleeve is located above the electric drill, which is convenient to move to the next traverse control point for the installation layout of the screw. However, even with the improvement in the prior art, drilling is still required. Content of the Utility Model

[0021] To make the above objects, features and advantages of the present application more obvious and understandable, the following detailed description of the specific implementation manners of the present application will be given in conjunction with the drawings of the specification. Obviously, the described embodiments are a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0022] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application may be practiced in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0023] Definition:

[0024] Adhesive solid 2: It has a non-solid state (fluid) and is viscous at this time; it also has a solid state to provide support; it is formed of a material with cement properties.

[0025] Water-absorbing layer 3, adhered to the surface of the adhesive solid, one is to promote the rapid setting of the adhesive solid, and the other is to have a certain role in assisting in fixing the shape of the adhesive solid when the adhesive solid is not formed.

[0026] Technical principle: The present application designs the traverse points using the property of additive manufacturing. It does not damage the original roof rock and reduces the risk of operation. At the same time, the traverse points manufactured by additive manufacturing can continue to be repaired or supplemented using the property of additive manufacturing, and the operation is flexible.

[0027] As Figure 2 shown, a mine cement traverse point is installed on the roof rock 1 and includes an adhesive solid 2, a water-absorbing layer 3 and a hook 4.

[0028] Among them, the adhesive solid 2 is adhered to the roof rock 1 and has the characteristic of changing from a non-solid state to a solid state; this physical characteristic facilitates the hook to sink into the adhesive solid 2 and can be fixed to the roof rock 1 after becoming solid. In some embodiments, the adhesive solid 2 is made of cement, which is convenient for maintenance, easy to obtain materials, and has a low cost. In some embodiments, the volume of the adhesive solid 2 is between 90 cm 3 -130 cm 3 , preferably 120 cm 3 , aiming to ensure rapid curing while maintaining stability, and at the same time, the embedding part 5 is directly embedded in the adhesive solid 2. The operation is convenient and the cost is low.

[0029] The hook 4 has a part embedded in the adhesive solid 2, and this part is the embedding part 5; a part is exposed outside the adhesive solid 2, and this part is the exposed body 6; the exposed body 6 has a wire-passing hole. In some embodiments, the embedding part has an embedding part one and an embedding part two. One ends of the embedding part one and the embedding part two are both connected to the exposed body 6, and the other ends both have a bending structure relative to the exposed body 6. In some embodiments, in order to increase the stability between the hook 4 and the adhesive solid 2, the embedding part 5 and the exposed body 6 are an integral body, and the exposed body 6 has a wire-passing hole with a diameter not less than 1 cm.

[0030] In some embodiments, the exposed body 6 has a threading hole with a diameter of 1 cm relative to the surface of the adhesive body 2, which is convenient for use in hanging wire measurement as a wire point.

[0031] As an improved technical solution of the present application, the hook 4 is formed by bending a copper wire with a length of 8 cm and a thickness of 0.2 cm.

[0032] As an improved technical solution of the present application, the hook 4 is made of copper material.

[0033] The water absorption layer 3 adheres to the surface of the adhesive body 2; in order to improve the stability of the wire point, in some embodiments, paper can be used and adhered to the cement adhesive body, which can absorb excess moisture and accelerate curing and shaping. The paper is 10*15 cm.

[0034] Embodiment 1

[0035] Obtain a copper wire with a length of 8 cm and a thickness of 0.2 cm, and bend it in sequence to form a first embedding part, an exposed body 6 and a second embedding part. One end of the first embedding part and the second embedding part are both connected to the exposed body 6, and the other end has a bending structure relative to the exposed body 6. The exposed body 6 is provided with a threading hole, which is convenient for hanging a wire with a rope.

[0036] Wet the cement with water and knead it into a viscous and appropriately sized mass (the ratio of cement to water is 1:0.4, and the specific humidity is determined according to the on-site conditions and the humidity of the roadway roof); wet and wipe clean the roof position where the wire point is to be arranged with water or a rag; stick the cement mass to the roof wire point position; after sticking, adhere waste paper (water absorption layer) to the cement mass; bury the embedding part 5 of the hook in the cement, and the exposed body 6 is exposed from the cement mass and the threading hole is exposed.

[0037] Let it dry naturally, the cement mass becomes the adhesive body 2 which is firm and durable, and the embedding part of the hook also stably exists in the adhesive body 2.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and not to limit them. Although the present application has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present application, and they should all be covered within the scope of the claims of the present application.
