Description

Technical Field

[0001] This utility model relates to the field of mine measurement technology, and more specifically, to a coal mine underground tunneling measurement device. Background Technology

[0002] A mine shaft is a general term for the shafts, tunnels, equipment, surface buildings and structures that form an underground coal mine production system. Sometimes, inclined shafts, vertical shafts and adits in underground mine development are also referred to as mine shafts. At the same time, when tunneling underground in a coal mine, it is necessary to conduct underground surveys.

[0003] Patent document CN222045762U discloses a coal mine underground roadway excavation measuring device, belonging to the field of mine measurement technology. It includes a support frame, a base plate installed at the bottom of the frame, a spool rotatably mounted at the top of the frame, a measuring rope wound on the spool, a positioning post installed at the outer end of the measuring rope, and a frame plate on the inner side of the support frame, on which multiple positioning rods are placed. This invention, by setting positioning rods, can better taut the measuring rope during long-distance measurements, improving measurement accuracy. Furthermore, the positioning rods can expand the measuring range of the measuring rope while maintaining accuracy. The device also has a simple structure, is easy to operate, and has high maneuverability during roadway measurements.

[0004] After the measurement is completed, when retracting the measuring rope, due to the large amount of dust in the mine, it is easy for dust particles to stick to the measuring rope. Dust particles are usually quite coarse, and after adhering to the measuring rope, they will increase the friction between the measuring rope and components such as the rope winder and guide wheel. Over time, this will lead to accelerated wear of the rope winder and guide wheel, shortening the service life of the equipment. The dust in the mine may also contain moisture or other corrosive substances, which, if they adhere to the measuring rope for a long time, will corrode the material of the measuring rope, causing the measuring rope to lose strength and become prone to breakage. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a coal mine underground tunneling measurement device that can clean the dust adhering to the surface of the measuring rope when it is retracted, thereby improving the service life of the measuring rope.

[0006] A coal mine underground tunneling measurement device includes a base plate with rollers mounted on its lower end face. An equipment box and two sliding frames are fixedly connected to the base plate, and several fixing members slide between the two sliding frames. A winding mechanism is installed inside the equipment box, and a measuring rope is wound around the winding mechanism. The free end of the measuring rope passes through the equipment box and the fixing members. A cleaning mechanism is provided between the equipment box and the sliding frames, and the measuring rope passes through the cleaning mechanism. The cleaning mechanism includes a drive box and a connecting plate fixed to the base plate. Two rotating shafts are rotatably connected to the connecting plate, with one end of each shaft passing through and rotatably connected to the drive box. Soft brushes are fixed to the peripheral walls of the rotating shafts.

[0007] Furthermore, the soft brushes on the two rotating shafts are in contact with each other.

[0008] Furthermore, a gear is fixedly connected to one end of the rotating shaft inside the drive box, and the two gears mesh with each other. A drive motor is installed inside the drive box, and the output end of the drive motor is fixedly connected to either of the gears.

[0009] Furthermore, multiple rows of the soft brushes are fixed to the peripheral sidewall of the rotating shaft.

[0010] Furthermore, the winding mechanism includes a winding roller that rotates within the equipment housing, the measuring rope being wound around the winding roller, and a servo motor installed within the equipment housing, the output end of which is fixedly connected to the shaft end of the winding roller.

[0011] Furthermore, two vertical plates are fixed to the inner wall of the equipment box, and a pulley is rotatably connected between the two vertical plates, with the measuring rope wound around the pulley.

[0012] Furthermore, each of the two sliding frames has a sliding groove on its side that is close to each other. The fixing member includes a slider that slides in the sliding groove. The slider has a through hole and a cone is fixedly connected to the lower end of the slider.

[0013] Furthermore, a fastening bolt is screwed onto the slider.

[0014] Furthermore, a plug is fixed to the free end of the measuring rope.

[0015] Furthermore, a handrail is fixedly attached to the base plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Specific implementation examples:

[0026] like Figure 1-4As shown, a coal mine underground tunneling measurement device includes a base plate 1. Rollers 2 are mounted on the lower end face of the base plate 1 for movement. An equipment box 3 and two sliding frames 4 are fixedly connected to the base plate 1. Several fixing parts 5 slide between the two sliding frames 4. A winding mechanism 6 is installed inside the equipment box 3, and a measuring rope 7 is wound and wound onto the winding mechanism 6. The free end of the measuring rope 7 passes through the equipment box 3 and the fixing parts 5. During long-distance measurement, the fixing parts 5 are fixed to the measurement path to tighten the measuring rope 7 and improve measurement accuracy. A cleaning mechanism 8 is installed on the base plate 1 between the equipment box 3 and the sliding frames 4. The measuring rope 7 passes through the cleaning mechanism 8, which is used to clean dust adhering to the surface of the measuring rope 7. The cleaning mechanism 8 includes a drive box 81 and a connecting plate 82 fixedly connected to the base plate 1. A drive box 81 and a connecting plate 82 are rotatably connected to the connecting plate 82. There are two rotating shafts 83, one end of which is rotatably connected to the drive box 81. A soft brush 84 is fixedly connected to the peripheral wall of the rotating shaft 83. The measuring rope 7 passes between the two rotating shafts 83 and the soft brush 84 contacts the surface of the measuring rope 7. The soft brushes 84 on the two rotating shafts 83 can just make contact with each other. A gear 85 is fixedly connected to one end of the rotating shaft 83 inside the drive box 81. The two gears 85 mesh with each other. A drive motor 86 is installed inside the drive box 81. The output end of the drive motor 86 is fixedly connected to either gear 85. The output of the drive motor 86 causes the two gears 85 to rotate, cleaning the surface of the measuring rope 7 during the winding process, so as to improve the service life of the measuring rope 7. The drive box 81 is set up to protect the two gears 85 and prevent dust from adhering to the gears 85 and affecting the meshing and rotation of the two gears 85.

[0027] like Figure 1-4 As shown, multiple rows of soft brushes 84 are fixedly connected to the peripheral sidewall of the rotating shaft 83. In this embodiment, four rows of soft brushes 84 are provided.

[0028] like Figure 1-4 As shown, the winding mechanism 6 includes a winding roller 61 that rotates inside the equipment box 3. The measuring rope 7 is wound around the winding roller 61. The winding mechanism 6 also includes a servo motor 62 installed inside the equipment box 3. The output end of the servo motor 62 is fixedly connected to the shaft end of the winding roller 61. Two vertical plates 63 are fixedly connected to the bottom wall inside the equipment box 3. A pulley 64 is rotatably connected between the two vertical plates 63. The measuring rope 7 is wound around the pulley 64. The pulley 64 is used to change the direction of the measuring rope 7, so that the winding and unwinding of the measuring rope 7 is smoother. Through the output of the servo motor 62, and in conjunction with the push or pull device, the winding roller 61 can easily wind and unwind the measuring rope 7.

[0029] like Figure 1-4As shown, each of the two sliding frames 4 has a groove 41 on one side that is close to each other. The fixing member 5 includes a slider 51 that slides in the groove 41. The slider 51 has a through hole 52 for threading the measuring rope 7. The lower end of the slider 51 is fixedly connected to a cone 53 for inserting into the ground to fix the fixing member 5 on the measurement path and to tighten the measuring rope 7. The slider 51 is threaded with a fastening bolt 54. The lower end of the fastening bolt 54 is inserted into the through hole 52 and squeezes and fixes the measuring rope 7. The friction reduces the probability of relative sliding between the fixing member 5 and the measuring rope 7, thereby tightening the measuring rope 7.

[0030] like Figure 1-4 As shown, the free end of the measuring rope 7 is fixedly connected to the insertion rod 9. The insertion rod 9 is inserted into the mine surface to fix the free end of the measuring rope 7 to the mine surface, which facilitates the measurement of the tunneling length.

[0031] like Figure 1-4 As shown, a blocking mechanism 10 is provided on the side of the two sliding frames 4 away from the equipment box 3. The blocking mechanism 10 includes a baffle 101 rotatably connected to one of the sliding frames 4, and a locking post 102 fixedly connected to the other sliding frame 4. The baffle 101 is provided with a slot 103 adapted to the locking post 102. Rotating the baffle 101 will lock the slot 103 onto the locking post 102, which can block the fixing member 5 and prevent it from sliding out of the two sliding frames 4.

[0032] like Figure 1-4 As shown, a handrail 11 is fixedly connected to the base plate 1, and the handrail 11 is provided to facilitate the movement of the pushing or pulling device.

[0033] like Figure 1-4 As shown, the cover 13 is fixed to the equipment box 3 by fixing bolts 12. Removing the cover 13 makes it easy to replace the measuring rope 7.

[0034] Both drive motor 86 and servo motor 62 are electrically connected to an external power supply and to a control unit (not shown in the figure).

[0035] The working principle of the coal mine underground tunneling measurement device in this embodiment is as follows: During use, the measuring rope 7 is released through the winding mechanism 6, and the insertion rod 9 is inserted to the starting point of the measurement path. The measuring rope 7 is released in conjunction with the winding mechanism 6, and the device is moved. The fixing piece 5 is inserted at a suitable position on the measurement path, and then the fastening bolt 54 is tightened. The two adjacent fixing pieces 5 cooperate to tighten the measuring rope 7, thereby improving the measurement accuracy. When winding the measuring rope 7, all the fastening bolts 54 are unscrewed. During the winding process, the drive motor 86 is started to make the two gears 85 rotate, and the surface of the measuring rope 7 is cleaned during the winding process to improve the service life of the measuring rope 7.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
