Description

Technical Field

[0001] The present invention relates to a device for leveling and straightening objects, which can be used for leveling the positions of pipes, wires, equipment, etc. in mine tunnels. Specifically, it relates to a device for leveling and straightening pipelines in weakly cemented strata tunnels. Background Art

[0002] The requirements for mine standardization are getting higher and higher, requiring the pipes, wires, equipment, etc. in the tunnel to be uniform. The deformation of weakly bonded soft rock tunnels is large. In order to ensure compliance with mine standardization requirements. Especially when adjusting the pipelines in weakly bonded tunnels, due to the long tunnels, uneven surrounding rocks and large deformation, one person is required to observe and direct the straightness of the pipelines from a distance, and one person is required to make adjustments. However, the personnel's field of vision is limited and the sound propagation distance is limited, resulting in limited adjustment working distance and poor overall adjustment effect.

[0003] Therefore, if the present weakly cemented stratum roadway pipeline leveling and straightening device is adopted, the above-mentioned defects existing in the current underground construction can be solved. Summary of the invention

[0004] In view of this, the present invention provides a pipeline leveling and straightening device for weakly cemented stratum tunnels.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a pipeline leveling and straightening device for weakly cemented stratum tunnels, which is assembled from a fixing rod and an adjusting rod. The characteristic is that two of the devices are directly fixed on the supporting anchor rods of the tunnel, and the spacing between the two devices can be determined according to the operation needs and the on-site conditions of the weakly cemented soft rock tunnel. After fixing, tie the engineering wire on the adjusting rod and straighten it, which can be used as a reference for the object to be leveled and straightened.

[0006] Furthermore, the fixing rod is welded into a whole by an equal-strength anchor rod, a one-inch steel pipe, and an equal-strength nut. (The model and length of the accessories can be determined according to the model of the tunnel support anchor rod and actual needs). The equal-strength anchor rod, the one-inch steel pipe, and the equal-strength nut are connected in sequence from left to right.

[0007] Furthermore, the adjusting rod is welded into a whole by an equal strength anchor rod, an equal strength nut and a perforated nut. One end of the equal strength anchor rod is welded to the side of the equal strength nut, and the other end is welded to the bottom of the perforated nut.

[0008] Furthermore, the multi-angle leveling and straightening device is composed of a fixed rod, an adjusting rod and two identical equal-strength nuts. The adjusting rod is screwed onto the fixed rod, and an equal-strength nut is added to each side of the adjusting rod to play a positioning role. When working, two or more multi-angle leveling and straightening devices are required to be used together.

[0009] Since the present invention adopts the above technical solution, the device has the advantages and effects of using local materials, easy assembly, high efficiency and economy. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] In order to deepen the understanding of the present invention, the present invention is further described below in conjunction with an embodiment of a well mining tunnel in a weakly cemented stratum and the accompanying drawings. This embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0017] like Figure 1-5As shown, the "device for leveling and straightening pipelines in weakly cemented strata tunnels" of the present invention is mainly composed of a fixing rod 1 and an adjusting rod 2. The fixing rod 1 includes an adjusting rod and other strong anchor rods 1A, a one-inch steel pipe 1B and an adjusting rod and other strong nut 1C. The adjusting rod and other strong anchor rods 1A have a fixing function, which mainly supports and fixes the adjusting rod 2, and also acts as a slide rail for the adjusting rod 2, so that it can rotate on the anchor rod through the thread on the anchor rod. The right end of the adjusting rod and other strong anchor rods 1A is connected to the left end of the one-inch steel pipe 1C, and the welding part is near the middle position inside the steel pipe. The adjusting rod and other strong nut 1C are welded to the right end of the one-inch steel pipe 1B. A certain cylindrical empty groove is left in the whole formed by welding the one-inch steel pipe 1B and the strong nut 1C, which is combined with the support anchor rod and fixed on the tunnel, and has a connection function. The adjusting rod 2 includes an adjusting rod perforated nut 2A, an adjusting rod equal-strength anchor rod 2B and an adjusting rod equal-strength nut 2C. The adjusting rod equal-strength anchor rod 2B is vertically welded on the side of the adjusting rod equal-strength nut 2C, which mainly plays the role of adjusting the angle and orientation. The bottom of the adjusting rod perforated nut 2A is welded to the other end of the equal-strength anchor rod to fix the engineering line. The left end of the fixed rod equal-strength anchor rod 1A passes through the equal-strength nut 3A, the adjusting rod 2, and the positioning equal-strength nut 3B in turn. The left and right ends of the equal-strength nut 2B on the adjusting rod are respectively connected to the equal-strength nuts 3A and 3B. Tighten them to form a whole, and the adjusting rod 2 can move left and right on the fixed rod 1, and can also rotate 360° around the fixed rod 1.

[0018] Of course, there are many more specific implementations. For example, the adjustment rod 2 in the above specific implementation can be equipped with other components to achieve more functions, and the rest will not be described in detail in this article.

[0019] The following briefly introduces some relevant working principles and methods based on the above specific implementation methods: Figure 4 As shown, when operating the multi-angle leveling and straightening device of the above specific embodiment, first screw the right end of the straightening device onto the original tunnel support anchor rod to form a whole, and then start to adjust the gap between the positioning and equalizing nut 3 and the adjusting rod 2 so that the positioning nut will not hinder the rotation and left and right movement of the adjusting rod. Figure 5As shown, the rotation direction of the adjusting rod and the position from the one-inch steel pipe 1B are adjusted according to the specific conditions on site, and another set of multi-angle leveling and straightening devices are installed at another tunnel support anchor using the same process to ensure that the angles and positions of the adjusting rods of the two sets of straightening devices are the same. The spacing between the two devices can be determined based on operational needs and tunnel site conditions. After fixing, tie an engineering line to the adjusting rod and straighten it, which can be used as a reference for objects that need to be leveled and straightened. Since the present invention adopts the above-mentioned technical solution, this multi-angle leveling and straightening device has the advantages and effects of using local materials, easy assembly, high efficiency and economy. It should be particularly noted that the above is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been described above with a preferred embodiment, it is not used to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of equivalent changes using the above disclosed content without departing from the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
