Description

Technical Field

[0001] This utility model belongs to the technical field of coal mine mining equipment, specifically a laser fixing and adjusting device for underground tunneling. Background Technology

[0002] Laser positioning collimator is a special high-precision reference measuring instrument designed for the installation, maintenance and testing of large equipment. Its application in the coal mining industry is becoming more and more common. In particular, the coal mining industry needs to use laser positioning laser pointers to install structures during tunnel excavation to ensure the quality of tunnel construction and prevent tunnel deviation.

[0003] Existing laser fixing and adjustment devices for underground tunneling are too simple, mostly with a fixed structure design that requires the use of top anchor bolts for installation. They are inconvenient to adjust, have high limitations in use, and are generally not very convenient to use. Therefore, in order to address the above problems, a laser fixing and adjustment device for underground tunneling is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, particularly the overly simplistic and fixed-structure design of current underground tunneling laser fixing and adjustment devices that require top anchor bolts for installation, making adjustment inconvenient and limiting their usability, this invention proposes an underground tunneling laser fixing and adjustment device. This device utilizes magnetic force to quickly and securely attach the base plate to the top mesh, effectively ensuring the stability and safety of the mounting frame. The adjustment method is simple, convenient, and highly practical.

[0005] The technical solution adopted by this utility model to solve its technical problem is a laser fixing and adjusting device for underground tunneling, including a fixing plate, wherein stainless steel magnets are provided at the four corners of the fixing plate.

[0006] Protective chains are connected to the top diagonal positions of the fixed plate;

[0007] A rotating disk is provided with a mounting groove at the center of the bottom side of the fixed plate. A rotating shaft is rotatably mounted in the mounting groove, and the bottom end of the rotating shaft is connected to the rotating disk.

[0008] A vertical rod is provided, a connecting frame is installed on the bottom side of the rotating disk, a sleeve is provided on the top of the vertical rod, the sleeve is placed inside the connecting frame, a locking screw passes through the mounting holes of the sleeve and the connecting frame in sequence, a locking nut is rotatably installed on one end of the locking screw, and a swing rod is fixed on the side of the locking nut.

[0009] A sliding sleeve is slidably provided on the outer side of the vertical rod. A horizontal rod is fixed on the outer wall of the sliding sleeve. A screw hole is opened on the circumferential wall of the sliding sleeve. A first clamping screw is rotatably installed in the screw hole. Through the design of the adjusting sleeve and the adjusting screw, the installation height of the horizontal rod can be freely adjusted to ensure the laser installation requirements at different heights.

[0010] Preferably, the vertical rod has a hollow structure, and a chisel is movably inserted inside the vertical rod. A gravity plate is fitted at the bottom of the chisel, which can be used to calibrate the vertical rod vertically.

[0011] Preferably, the bottom side wall of the vertical rod is provided with a positioning screw hole, and a positioning screw is rotatably installed in the positioning screw hole. The bottom side of the fixing plate is provided with scale lines, and a connecting plate is fixed to the side of the rotating disk. The connecting plate is provided with a screw hole inside, and a second clamping screw is installed in the screw hole. In order to ensure that the vertical rod is naturally vertical, after the vertical rod swings to a vertical state, the position of the rotating disk is locked by rotating the second clamping screw, thereby locking the naturally drooping vertical rod and ensuring that the vertical rod is a vertical structure.

[0012] The advantages of this utility model are:

[0013] The base plate is equipped with stainless steel magnets at its four corners, allowing it to be quickly and securely attached to the top net using magnetic force. The integrated design of the base plate and vertical rod effectively ensures the stability of the mounting frame and guarantees its safety during use.

[0014] The design of protective chains at the two corners of the fixed base plate can prevent injury to personnel when the laser frame falls, ensuring the safety of the installation frame.

[0015] By adjusting the design of the sliding sleeve and the adjusting screw, the sliding sleeve and the first clamping screw work together to freely adjust the installation height of the crossbar to ensure the laser installation requirements at different heights, greatly reducing the limitations of the mounting bracket. The sliding sleeve is limited and fixed by the first clamping screw, and the adjustment method is simple, convenient and highly practical. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figure 1-5 As shown, a laser fixing and adjusting device for underground tunneling includes a fixing plate 1, and stainless steel magnets 3 are provided at the four corners of the fixing plate 1.

[0025] Protective chain 2, the top side of the fixing plate 1 is diagonally connected to the protective chain 2;

[0026] The rotating disk 16 has an installation groove at the center of the bottom side of the fixed plate 1, and a rotating shaft 19 is rotatably installed in the installation groove. The bottom end of the rotating shaft 19 is connected to the rotating disk 16.

[0027] The vertical rod 9 has a connecting frame 4 installed on the bottom side of the rotating disk 16. The top of the vertical rod 9 is provided with a sleeve 8, which is located inside the connecting frame 4. The locking screw 7 passes through the mounting holes of the sleeve 8 and the connecting frame 4 in sequence. A locking nut 6 is rotatably installed at one end of the locking screw 7. A swing rod 5 is fixed on the side of the locking nut 6.

[0028] A sliding sleeve 12 is slidably provided on the outer side of the vertical rod 9, and a horizontal rod 10 is fixed on the outer side wall of the sliding sleeve 12.

[0029] The bottom side of the fixed plate 1 is provided with scale lines, and the side of the rotating disk 16 is fixed with a connecting plate 17. The connecting plate 17 is provided with a screw hole, and a second clamping screw 18 is installed in the screw hole.

[0030] A screw hole is provided on the circumferential wall of the sliding sleeve 12, and a first clamping screw 11 is rotatably installed in the screw hole;

[0031] When using the underground tunneling laser fixing and adjustment device, with the cooperation of the stainless steel magnet 3, the fixing plate 1 can be adsorbed at a suitable position on the top plate, and the protective chain 2 can be fixed on the top plate mesh to prevent the laser frame from falling and injuring personnel. Then, the laser pointer can be installed at a suitable position on the crossbar 10 according to the needs of the site.

[0032] Before installing the laser pointer, under the assistance of gravity, since the vertical rod 9 is in a downward swinging state, when the fixing plate 1 is in an adsorption and fixing state, the fixing plate 1 is in an inclined state. After the fixing plate 1 is fixed, when the rotating disk 16 rotates freely, the vertical rod 9 also swings down automatically, which can ensure that the vertical rod 9 is naturally vertically set. After the vertical rod 9 swings to a vertical state, the position of the rotating disk 16 is locked by rotating the second clamping screw 18. By moving the swing rod 5, with the cooperation of the locking nut 6 and the cooperation of the two side walls of the connecting frame 4, the sleeve 8 is fixed, thereby locking the naturally drooping vertical rod 9, ensuring that the vertical rod 9 is a vertical structure, and ensuring the horizontal state of the crossbar 10. Then the laser pointer is installed to better achieve the initial positioning of the laser pointer.

[0033] When height adjustment is required, the sliding sleeve 12 slides on the vertical rod 9 to the appropriate position, and the first abutting screw 11 is tightened to fix the sliding sleeve 12 on the vertical rod 9. The whole operation process is simple and convenient. Compared with the existing underground tunneling laser fixing and adjustment device, this utility model can improve the overall ease of use, adjustability and practicality of the laser installation structure through design.

[0034] The vertical rod 9 has a hollow structure, and a drill rod 15 is movably inserted inside the vertical rod 9. A gravity plate 14 is fitted at the bottom of the drill rod 15.

[0035] The bottom side wall of the vertical rod 9 is provided with a positioning screw hole, and a positioning screw 13 is rotatably installed in the positioning screw hole. In order to better cooperate in adjusting the position of the laser positioning instrument, a gravity plate 14 is provided at the bottom of the rod 15, which can increase the bottom gravity and achieve vertical calibration of the vertical rod 9 by its own weight.

[0036] When the laser positioning device is difficult to hoist and install, the extension rod 15 can be used to lock the rod 15 with the positioning screw 13. The rod 15 and the vertical rod 9 can be combined to form a support rod. The bottom of the vertical rod 9 is inserted into the ground to support and fix the laser positioning device, thus achieving vertical support and fixation of the laser positioning device, which can be better applied to the underground mining environment.

[0037] In the description of this specification, the basic principles, main features and advantages of this utility model have been shown and described above. For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
