Description

Technical Field

[0001] This utility model relates to the technical field of underground ramp construction and underground well construction auxiliary equipment, and in particular to a slope indicator device. Background Technology

[0002] In metal and non-metal mines, during the construction of underground ramps and shafts, the following methods are mainly used for slope control to ensure that the project is constructed according to the design:

[0003] (1) Using a fixed laser pointer for construction guidance is a common method in long-distance slope construction. Its advantages are accuracy and intuitiveness, and it can be operated by construction personnel after installation, reducing the need for engineering and technical personnel. The disadvantages are that it is inconvenient to use on short-distance slopes because the vibration from rock drilling and blasting can cause the fixed laser pointer to deflect; the instrument is inconvenient to set up and basically cannot guide the construction of the well; the cost is relatively high; and it can only be used in straight tunnels and cannot be used in curved tunnel construction.

[0004] (2) The surveyor marks the slope line on-site. This method involves professional technicians using a total station to mark slope indicator lines on both sides of the tunnel to provide slope guidance to the construction workers. It is suitable for projects with a small workload and sufficient engineering technicians. The disadvantage is that it consumes a large amount of engineering technician manpower, and if the slope line is not followed up in time, it will affect the rock drillers' drilling and hole layout.

[0005] (3) The main method of construction of the well is to use the drilling of the construction guide hole in the pit to guide the excavation. The disadvantage of this method is that it consumes a certain amount of money. The construction method described in the second article above is difficult to lay out the slope line of the artificial well, which is dangerous and consumes a lot of manpower.

[0006] The existing electronic slope rulers on the market are slope measuring instruments. Although they can emit laser lines, they cannot be used as slope indicators on construction sites. Utility Model Content

[0007] To address the problems existing in the prior art, this application proposes a slope indicator device that can quickly, intuitively, and accurately provide slope markings for construction workers during the construction of roadways and mining areas, thereby improving the construction speed and quality of roadways and mining areas.

[0008] To achieve the above objectives, this application proposes a slope indicating device, comprising a disc-shaped base, a support frame mounted on the lower surface of the disc-shaped base, a support rod fixedly mounted at the center of the upper surface of the disc-shaped base, a rotating base body sleeved on the support rod, and a first fastening screw on the rotating base body. When the first fastening screw is loosened, the rotating base body can slide up and down along the support rod and can rotate around the axis of the support rod. By tightening the first fastening screw, the rotating base body and the support rod can be relatively fixed. A vertical connecting plate and a connecting plate are fixedly connected to one side of the rotating base body. A mounting plate is hinged to the upper end of the connecting plate. An angle adjustment mechanism can adjust the angle between the mounting plate and the connecting plate. A slope gauge is provided on the upper surface of the mounting plate.

[0009] In some embodiments, the support frame has the following structure: three hinge points are provided at equal intervals along the circumference on the lower surface of the disc-shaped base, and a support leg is hinged at each hinge point. A connecting rod is detachably connected between two adjacent support legs. When it needs to be stored, the connecting rod is removed, and the support leg can move closer to the axis of the disc-shaped base. When in use, a connecting rod is connected between two adjacent support legs.

[0010] In some embodiments, each support leg is provided with two hinge points spaced apart, referred to as the upper hinge point and the lower hinge point, respectively. When the support frame is required to provide stable support, the three support legs are opened, and a connecting rod is connected between two adjacent support legs. One end of the connecting rod is hinged to the upper hinge point of the support leg on the left, and the other end of the connecting rod is hinged to the lower hinge point of the support leg on the right. The lower end of each connecting rod is detachably connected to the corresponding support leg.

[0011] In some embodiments, the angle adjustment mechanism includes a connecting column, one end of which is fixed to the connecting plate, and the other end of which is provided with a nut. An adjusting screw is used in conjunction with the nut, and the upper end of the adjusting screw abuts against the lower surface of the mounting plate. By rotating the adjusting screw, the angle between the mounting plate and the connecting plate can be adjusted.

[0012] In some embodiments, the bottom of the slope ruler is magnetic, allowing it to adhere to the upper surface of the mounting plate.

[0013] In some embodiments, a level is provided at the center of the upper surface of the slope gauge along the width direction of the slope gauge to visualize the horizontal indication in the width direction of the slope gauge.

[0014] In some embodiments, a laser light is also included, which is disposed on the upper surface of the slope ruler near the position where the laser line is emitted.

[0015] The beneficial effect of the solution in this application is that the slope indicator device has the advantages of simple structure, easy to carry, low technical threshold for use, convenient and flexible installation, and low cost, and can quickly and conveniently indicate the slope in the well.

Detailed Implementation

[0019] The specific embodiments of this application will be further described below with reference to the accompanying drawings.

[0020] In the description of this application, it should be understood that the terms "first," "second," etc., are used to distinguish similar objects, rather than to describe or indicate a specific order or sequence. The terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0021] like Figures 1-2 As shown, the slope indicator device involved in this application includes a disc-shaped base 5. A support frame is mounted on the lower surface of the disc-shaped base 5. Specifically, the support frame is a retractable support frame for easy carrying. In this embodiment, the structure of the support frame is as follows: three hinge points 4 are provided at equal intervals along the circumference on the lower surface of the disc-shaped base 5. Each hinge point 4 is located near the outer circle of the disc-shaped base 5. A support leg 1 is hinged at each hinge point 4. A connecting rod 2 is detachably connected between two adjacent support legs 1. When it needs to be stored, the connecting rod 2 is removed, and the support leg 1 can move closer to the axis of the disc-shaped base 5. When in use, the connecting rod 2 is connected between two adjacent support legs 1.

[0022] Specifically, each support leg 1 has two hinge points spaced apart, designated as the upper hinge point 3 and the lower hinge point 13. When the support frame needs to provide stable support, the three support legs 1 are opened, that is, they are dispersed away from the axis of the disc-shaped base 5. A connecting rod 2 connects two adjacent support legs 1. One end of the connecting rod 2 is hinged to the upper hinge point 3 of the support leg 1 on the left, and the other end of the connecting rod 2 is hinged to the lower hinge point 13 of the support leg 1 on the right, thus forming a stable three-legged support. The lower end of each connecting rod 2 is detachably connected to the corresponding support leg 1. This structural design allows the connection between the lower end of the connecting rod 2 and the corresponding support leg 1 to be disassembled when the slope indicator device is not used, so that the support leg 1 can be moved closer to the axis of the disc-shaped base 5 for easy storage of the support frame.

[0023] A support rod 6 is fixedly provided at the center of the upper surface of the disc-shaped base 5. A rotating base 9 is sleeved on the support rod 6. A first fastening screw 8 is provided on the rotating base 9. The first fastening screw 8 is threadedly connected to the rotating base 9 along the radial direction of the support rod 6, and the first fastening screw 8 can abut against the support rod 6. When the first fastening screw 8 is loosened, the rotating base 9 can slide up and down along the support rod 6 and can rotate around the axis of the support rod 6. After adjusting the rotating base 9 to the required height and direction, the relative fixation of the rotating base 9 and the support rod 6 can be achieved by tightening the first fastening screw 8.

[0024] A vertical connecting plate connected to one side of the rotating base 9 is fixedly connected to a connecting plate 7. Specifically, the vertical connecting plate has an internal threaded hole, and the connecting plate 7 has a through hole. The connecting plate 7 and the vertical connecting plate are fixedly connected by a second fastening screw 22. A mounting plate 16 is hinged to the upper end of the connecting plate 7 via a hinge 10. An angle adjustment mechanism can adjust the angle between the mounting plate 16 and the connecting plate 7. In this embodiment, the angle adjustment mechanism includes a connecting column. One end of the connecting column is fixed to the connecting plate 7, and the other end of the connecting column is provided with a nut 20. An adjusting screw 21 is used in conjunction with the nut 20. The upper end of the adjusting screw 21 abuts against the lower surface of the mounting plate 16. By rotating the adjusting screw 21, the angle between the mounting plate 16 and the connecting plate 7 can be adjusted.

[0025] A slope ruler 11 is provided on the upper surface of the mounting plate 16. In this embodiment, the slope ruler 11 is a commercially available long strip-shaped electronic reading slope ruler with the function of emitting laser horizontal lines. It has a strong magnet at the bottom and can be adsorbed onto the upper surface of the mounting plate 16.

[0026] To visualize the horizontal indication of the slope gauge 11 in the width direction, a level 17, such as a bubble level, is provided at the middle position of the upper surface of the slope gauge 11 along the width direction of the slope gauge 11. The level 17 is used to adjust the level of the slope gauge 11 in the width direction.

[0027] To adapt to various slope indication situations, the slope indication device involved in this application also includes a laser light 12, which is disposed on the upper surface of the slope ruler 11 near the position where the laser line is emitted. The laser light 12 has the function of single-point slope indication during underground tunneling operations.

[0028] In practical use, the slope indicator device involved in this application is first set up at the cut point or center line point of the roadway. The level of the device is roughly adjusted, and a laser electronic slope ruler is installed. Then, the level is precisely adjusted, and the required slope is adjusted to meet the design slope requirements. The laser emits an infrared horizontal line to mark the waistline of the roadway, and the center line of the roadway can also be extended. The accuracy is ±0.25°, which can fully meet the construction requirements.

[0029] The slope indicator device involved in this application can be applied to a variety of scenarios, such as: controlling the slope in the construction of upward slopes, controlling the slope in the construction of downward slopes, controlling the height of the stope roof in the upward horizontal layered approach mining method, controlling the height of the stope roof in the downward horizontal layered approach mining method, setting up waist lines, laying tracks in horizontal tunnels, and slope indication in the construction of raises, etc.

[0030] The slope indicator device involved in this application has the advantages of simple structure, easy to carry, low technical threshold for use, convenient and flexible installation, and low cost. It can quickly and conveniently indicate the slope in the mine. If it is promoted and used in mines, it will have great economic and social benefits.

[0031] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
