This device improves upon the low efficiency of single-point positioning. A mounting base is fixed to the top of a tripod via a screw, and the mounting base has a movable cavity. A screw shaft is connected to the bottom of the mounting shell via a connecting frame. The screw shaft rotates to mount the mounting frame, and a movable plate is fixed to the bottom of the mounting frame. The movable plate is embedded in the movable cavity to achieve fine-tuning of the plane. A positioning plate with a matrix of light-transmitting holes is inserted into the front of the mounting shell, and an illumination lamp is installed inside.

It is mainly used for rapid positioning of blasting holes in tungsten mines.

Description

Technical Field

[0001] This utility model relates to the field of mining engineering equipment technology, and in particular to a blasting hole positioning device for tungsten mines. Background Technology

[0002] In tungsten mining, the precise location of blasting holes directly affects the blasting effect and the quality of the mine tunnel formation. Traditional positioning methods mainly rely on manual string measurement or laser pointer illumination, which is inefficient and generally only marks one hole at a time, requiring multiple adjustments. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of low efficiency in existing technologies by proposing a ore vein blasting hole positioning device for tungsten mine mining.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Tungsten mine mining employs a vein blasting hole positioning device, including a tripod;

[0006] Mounting base, located on top of the tripod;

[0007] The mounting housing has a positioning plate detachably inserted into one side, the positioning plate has multiple light-transmitting holes, and an illumination lamp is fixedly installed inside the mounting housing.

[0008] A screw shaft, the outer wall of which is rotatably fitted with a connecting frame and a mounting frame, the connecting frame being fixedly connected to the bottom of the mounting shell;

[0009] A movable plate is fixedly mounted on the bottom of the mounting frame;

[0010] The mounting base has a movable cavity inside, and the top of the mounting base has a through hole that communicates with the movable cavity. The movable plate is movably disposed in the movable cavity through the through hole.

[0011] When the illumination lamp is turned on, the light passes through the light-transmitting hole and forms multiple positioning light spots on the mine wall, which facilitates the positioning of the blasting hole.

[0012] In one possible design, a screw is fixedly installed at the bottom of the mounting base, the bottom end of the screw passes through the placement platform of the tripod, and a fixing nut is provided below the placement platform, the fixing nut being threaded onto the outer wall of the screw.

[0013] In one possible design, the plurality of light-transmitting holes are arranged in a matrix on the surface of the positioning plate.

[0014] In one possible design, a tightening nut is threaded onto the outer wall of the screw shaft.

[0015] In one possible design, the bottom of the movable plate has a bottom groove, a support plate is provided in the bottom groove, a connecting plate is fixedly connected to the top of the support plate, the top of the connecting plate slides through the movable plate and extends to one side of the mounting frame, the top of the connecting plate has an inclined surface, and the tightening nut cooperates with the inclined surface.

[0016] In one possible design, a battery is installed inside the mounting housing, the battery is electrically connected to the illumination lamp, and is provided with a charging interface.

[0017] In this application, during actual use, after the tripod is placed in the tungsten mine shaft, the screw at the bottom of the mounting base is passed through the tripod's placement platform, and then a fixing nut is screwed on below to fix it to the tripod, completing the assembly. After that, the illumination light is turned on, and the light from the illumination light will shine through the light-transmitting hole on the surface of the positioning plate onto the mine wall for positioning, so that construction workers can directly drill holes or use equipment such as inkjet guns to mark it before drilling.

[0018] Furthermore, by moving the movable plate within the movable cavity in a planar manner, fine adjustments can be made to the lateral angle and distance. The connecting frame can be rotated along the screw shaft to adjust the vertical angle of the irradiation. Once the angle is determined, the tightening nut can be tightened. Tightening the nut will compress the side wall of the mounting frame, causing it to elastically deform and clamp the connecting frame in place, thus fixing the angle of the mounting shell. When the nut is tightened, it will push the inclined surface of the connecting plate, thereby compressing the connecting plate and the bottom abutment plate, causing the abutment plate to press against the bottom wall of the movable cavity through friction, completing the final fixation.

[0019] In this utility model, the tungsten mine adopts a vein blasting hole positioning device. Through the positioning plate and the illumination lamp, multiple positioning light spots can be simultaneously irradiated by the light-transmitting hole, thereby achieving the effect of hole positioning, which makes it convenient for construction personnel to drill and blast holes.

[0020] In this utility model, the tungsten mine adopts a vein blasting hole positioning device. Through the adjustment mechanism, after the device is set up, it can be finely adjusted so that the light spot can be more accurately irradiated on the mine wall.

[0021] In this invention, the hole position is projected onto the mine wall by illumination, making it easy for construction workers to locate it and thus enabling direct drilling operations. Alternatively, the hole can be marked before subsequent operations. The operation is simple and convenient, improving overall efficiency. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] In one embodiment: Reference Figure 1-2 The positioning device includes: a tripod 1, a mounting base 2, a mounting shell 6, and an angle adjustment mechanism. The tripod 1 has a placement platform on top. The mounting base 2 passes through the placement platform via a screw 5 welded to the bottom and is threadedly connected to a fixing nut 4 below the placement platform. By tightening the fixing nut 4, the mounting base 2 is rigidly fixed to the tripod 1.

[0029] refer to Figure 3-4 The mounting shell 6 is a cuboid shell structure, with a replaceable positioning plate 7 inserted into its front side wall. The surface of the positioning plate 7 has light-transmitting holes 3 arranged in a matrix, and an illumination lamp 8 is fixed inside the mounting shell 6.

[0030] The angle adjustment mechanism consists of a screw shaft 10, a connecting frame 9, a mounting frame 12, and a moving plate 11.

[0031] The connecting bracket 9 is welded to the bottom surface of the mounting shell 6, and both the connecting bracket 9 and the mounting bracket 12 are sleeved on the outer wall of the screw shaft 10 through the shaft hole. The outer wall of the screw shaft 10 is threaded with a tightening nut 17.

[0032] The movable plate 11 is welded to the bottom of the mounting bracket 12. The size of the movable plate is smaller than the movable cavity 13 inside the mounting base 2, and the size of the mounting bracket 12 is smaller than the through hole 18 at the top of the mounting base 2, so that it can be moved and adjusted in a plane. A bottom groove 14 is opened on the bottom surface of the movable plate 11, in which a backing plate 15 is embedded. A connecting plate 16 welded to the top of the backing plate 15 passes through the movable plate 11, and the top of the connecting plate 16 is provided with a slope.

[0033] Specifically, first, support the tripod 1 on the mine floor, adjust the length of the legs to make the platform level, then pass the screw 5 of the mounting base 2 through the platform, tighten the fixing nut 4 to complete the assembly, and then turn on the illumination lamp 8. The light will form an illumination point on the mine wall through the light-transmitting hole 3 of the positioning plate 7, so that the construction personnel can directly use the drilling machine to drill the blasting hole, or use the inkjet gun to mark the hole position before subsequent drilling operations.

[0034] Furthermore, by pushing the movable plate 11 to slide horizontally within the movable cavity 13, the lateral position of the irradiation point can be adjusted. By using the connecting frame 9 with the screw shaft 10 as the rotation point, the vertical irradiation angle can be adjusted, which facilitates fine-tuning and ensures accuracy. Then, the tightening nut 17 can be tightened, and its end face presses against the side wall of the mounting frame 12 to produce elastic deformation, thereby clamping and fixing the connecting frame 9. Tightening the nut 17 will simultaneously push the inclined surface of the connecting plate 16 to move the abutment plate 15 downward. Through friction, the movable plate 11 is fixed to the bottom wall of the movable cavity 13, thereby ensuring stability.

[0035] This application can be used in the field of mining engineering equipment, or in other fields applicable to this application.

[0036] In another embodiment: Reference Figure 1 The tungsten mine uses a vein blasting hole positioning device, which is applied to the field of mining engineering equipment. The housing 6 is equipped with a battery pack and a charging interface. The illumination lamp 8 forms a power supply circuit with the battery through a control switch.

[0037] However, as is well known to those skilled in the art, the working principle and wiring method of the illumination lamp 8 are commonplace and are all conventional means or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
