Description

Technical Field

[0001] This utility model relates to the field of mine surveying technology, specifically to a simple positioning device for mine surveying control points. Background Technology

[0002] In mining operations, accurate surveying is a key prerequisite for ensuring mining safety and efficiency, and the accurate positioning of survey control points is the core foundation of surveying work. The complex and ever-changing terrain and working environment of mines place stringent requirements on the positioning devices for survey control points.

[0003] Current mine surveying control point positioning devices generally have a structure similar to that described in patent application number "CN217583891U," which includes a base and a housing. Two vertical electric lifting rods are symmetrically arranged in the center of the top wall of the base, and four vertical screws are threaded through both sides of the top wall of the base. This utility model features multiple drainage and heat dissipation holes in the bottom wall of the housing, which connect to the inner cavity. These holes allow for heat dissipation of the motor and also facilitate timely drainage when rainwater enters the housing through the gap connecting the motor output rod and the top wall of the housing. Furthermore, a level is installed on the top of the housing to check if the positioning device is level. By adjusting the position of the four screws relative to the base—that is, rotating the screws to make the support rods contact the ground—the angle of the base tilts at different positions of the support rods. Combined with the level, the positioning device can be adjusted to be level.

[0004] However, the existing mine surveying control point positioning devices have complex height adjustment operations, relying on cumbersome bolt fastening or multi-part splicing structures. This not only consumes a lot of manpower and time, but also easily causes height deviations during the adjustment process, affecting measurement accuracy. Furthermore, the fixing methods are not flexible and efficient enough to meet the rapid fixing needs under different geological conditions in mines. Insecure fixing can easily cause the surveying control points to shake, and it is extremely inconvenient to move between different work areas in the mine, reducing the efficiency of mine surveying work.

[0005] Therefore, this utility model proposes a simple positioning device for mine measurement control points to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a simple positioning device for mine measurement control points, which solves the problem that the height adjustment operation is complicated and it is not convenient to position in different work areas in the existing technology.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A simple positioning device for mine surveying control points includes a vertical tube, a vertical rod slidably connected to the inner cavity of the vertical tube, a fixing assembly fixedly connected to the top of the vertical tube, and a folding positioning assembly movably connected to the surface of the vertical tube. The fixing assembly includes a mounting groove at the top of the vertical tube, a threaded tube fixedly connected to the inner cavity of the mounting groove via a bearing, a lead screw threadedly connected to the inner cavity of the threaded tube, the other end of the lead screw penetrating into the inner cavity of the vertical tube, a pin hole for cooperating with the lead screw on the surface of the vertical rod, and a bevel gear fixedly connected to one end of the threaded tube. The top of the gear meshes with a drive bevel gear ring, the surface of which is movably connected to the top of the vertical tube via a bearing; the folding positioning assembly includes a fitting groove formed on the surface of the vertical tube, a sliding groove formed on one side of the fitting groove, a support rod slidably connected to the inner cavity of the fitting groove, a screw fixedly connected to the top of one side of the support rod, the other end of the screw passing through the inner cavity of the sliding groove and extending to the outside of the vertical tube, a locking nut threadedly connected to the end of the screw located outside the vertical tube, and a fixing plate movably connected to the bottom of the support rod via a damping bearing.

[0009] Furthermore, the vertical tube is hollow, and the vertical rod is slidably connected to the central cavity of the vertical tube. The hollow design of the vertical tube ensures smooth sliding of the vertical rod, provides a stable foundation for the height adjustment function, and ensures that the entire device has a reasonable structure and stable operation.

[0010] Furthermore, a turntable is fixedly connected to the top of the drive bevel gear ring. The surface of the turntable is provided with anti-slip texture. The anti-slip texture on the surface of the turntable increases the friction of the operator's hand when operating the drive bevel gear ring, making rotation more effortless and convenient, less prone to slipping, and improving the comfort and efficiency of height adjustment operation.

[0011] Furthermore, the mounting groove is configured to penetrate and communicate with the axial cavity of the vertical tube. The end of the mounting groove away from the axial cavity of the vertical tube is open. The connection between the mounting groove and the axial cavity of the vertical tube ensures that the lead screw can smoothly penetrate into the inner cavity of the vertical tube and cooperate with the pin hole of the vertical rod, ensuring smooth connection of each component of the fixing assembly and realizing the normal operation of the height adjustment function.

[0012] Furthermore, limit grooves are provided on both the upper and lower sides of one end of the lead screw. A limit block is slidably connected to the inner cavity of the limit groove. The other end of the limit block is fixedly connected to the inner wall of the mounting groove. The limit groove and the limit block cooperate to restrict the movement trajectory of the lead screw, prevent the lead screw from deviating or shaking during rotation, ensure the stable cooperation between the lead screw and the solenoid, and improve the accuracy and reliability of height adjustment.

[0013] Furthermore, the side of the locking nut that contacts the vertical tube is arc-shaped. The arc design of the locking nut allows it to fit tightly against the surface of the vertical tube, providing greater friction when the nut is tightened to fix the support rod, thus enhancing the fixing effect and preventing the support rod from loosening.

[0014] Furthermore, a handle is fixedly connected to both sides of the locking nut, and the surface of the handle is provided with anti-slip texture. The handle and anti-slip texture on both sides of the locking nut make it easy for the operator to quickly turn the locking nut and adjust the position of the support rod, thereby improving the convenience and efficiency of the operation of the folding positioning component.

[0015] Furthermore, the surface of the fixing plate is provided with mounting holes, and the inner cavity of the mounting holes is fixedly connected to the mine by bolts. The design of the mounting holes facilitates the bolts to firmly connect the device to the mine ground, further enhancing the stability of the positioning device and ensuring the accuracy of the measurement work.

[0016] The present invention has the following beneficial effects.

[0017] 1. This utility model achieves efficient and precise height adjustment through a fixed component. The operator rotates the drive bevel gear ring, which drives the bevel gear, causing the screw tube to rotate. The lead screw then moves along the thread inside the screw tube, inserting or disengaging into the pin hole on the surface of the vertical rod, thereby easily adjusting the height of the vertical rod inside the vertical tube. The entire adjustment process is simple to operate, requiring no complex splicing. Furthermore, the cooperation between the lead screw and the pin hole can accurately lock the height, effectively avoiding height deviation, greatly improving the efficiency and accuracy of measurement work, and meeting the needs of mine surveying for precise positioning of control point height.

[0018] 2. The fitting groove, sliding groove, support rod, screw, locking nut and fixing plate of this utility model work together. The angle and position of the support rod can be quickly adjusted by simply turning the locking nut. The fixing plate at the bottom can be initially fixed to the mine by pressing it with ore, and then connected to the mine ground by bolts to enhance the stability of the fixation. At the same time, the folding design makes it easy to quickly transfer and store the device between different working areas, reducing transportation and storage costs and improving the flexibility and convenience of mine surveying work.

[0027] Example 1

[0028] like Figure 1-5As shown, this utility model is a simple positioning device for mine surveying control points, including a vertical tube 1, a vertical rod 2 slidably connected to the inner cavity of the vertical tube 1, a fixing component 3 fixedly connected to the top of the vertical tube 1, and a folding positioning component 4 movably connected to the surface of the vertical tube 1. The fixing component 3 includes an installation groove 31 opened at the top of the vertical tube 1, a screw tube 32 fixedly connected to the inner cavity of the installation groove 31 via a bearing, a lead screw 33 threadedly connected to the inner cavity of the screw tube 32, the other end of the lead screw 33 penetrating into the inner cavity of the vertical tube 1, a pin hole 34 for cooperating with the lead screw 33 opened on the surface of the vertical rod 2, and a bevel gear 35 fixedly connected to one end of the screw tube 32. The top of the gear 35 is engaged with a drive bevel gear ring 36. The surface of the drive bevel gear ring 36 is movably connected to the top of the vertical tube 1 through a bearing. The folding positioning assembly 4 includes a fitting groove 41 opened on the surface of the vertical tube 1. A sliding groove 42 is opened on one side of the fitting groove 41. A support rod 43 is slidably connected to the inner cavity of the fitting groove 41. A screw 44 is fixedly connected to the top of one side of the support rod 43. The other end of the screw 44 passes through the inner cavity of the sliding groove 42 and extends to the outside of the vertical tube 1. A locking nut 45 is threadedly connected to the end of the screw 44 located outside the vertical tube 1. A fixing plate 46 is movably connected to the bottom of the support rod 43 through a damping bearing.

[0029] Furthermore, the vertical tube 1, as the main support structure of the entire positioning device, adopts a hollow design. Its axial cavity provides space for the vertical rod 2 to slide up and down, ensuring that the vertical rod 2 can move smoothly within the vertical tube 1 to achieve the height adjustment function. The screw tube 32 and the lead screw 33 are threaded together. When the screw tube 32 rotates, the lead screw 33 can move precisely left and right. The pin hole 34 on the surface of the vertical rod 2 corresponds precisely to the lead screw 33. When the lead screw 33 is inserted into the pin hole 34, the vertical rod 2 can be firmly fixed at the corresponding height. The meshing design of the bevel gear 35 and the drive bevel gear ring 36 provides a convenient transmission method for the rotation of the screw tube 32. The operator only needs to rotate the drive bevel gear ring 36 to easily... The screw tube 32 rotates, and the fitting groove 41 is used to accommodate the support rod 43, allowing it to rotate and slide flexibly; the sliding groove 42 provides a channel for the movement of the screw 44, ensuring that the screw 44 can move; the support rod 43, as the main support component, can adjust its angle according to the actual terrain; the screw 44 cooperates with the locking nut 45, and by tightening or loosening the locking nut 45, the position of the support rod 43 can be quickly fixed or adjusted; the bottom fixing plate 46 is connected to the support rod 43 through a damping bearing, which can ensure that the fixing plate 46 adapts to different ground conditions and provides stable support. The fixing plate 46 can be firmly connected to the mine ground through the mounting holes using bolts, realizing the stable fixation of the device.

[0030] Example 2

[0031] like Figure 1-5As shown, based on Embodiment 1, the vertical tube 1 adopts a hollow design, and the vertical rod 2 is slidably connected in its axial cavity. A turntable is fixedly connected to the top of the drive bevel gear ring 36. The surface of the turntable is provided with anti-slip texture. The mounting groove 31 is connected through the axial cavity of the vertical tube 1, and the end of the mounting groove 31 away from the axial cavity of the vertical tube 1 is open. Limiting grooves 37 are opened on both the upper and lower sides of one end of the lead screw 33. Limiting blocks 38 are slidably connected to the inner cavity of the limiting groove 37. The other end of the limiting block 38 is fixedly connected to the inner wall of the mounting groove 31. The side of the locking nut 45 that contacts the vertical tube 1 adopts an arc design. The surface of the fixing plate 46 is provided with mounting holes. The inner cavity of the mounting holes is fixedly connected to the mine by bolts. A handle is fixedly connected to both sides of the locking nut 45. The surface of the handle is provided with anti-slip texture.

[0032] Furthermore, the hollow design of the vertical tube 1 ensures smooth sliding of the vertical rod 2, providing a stable foundation for the height adjustment function and ensuring the rational structure and stable operation of the entire device. The anti-slip texture on the surface of the turntable increases the friction of the operator's hand when operating the drive bevel gear ring 36, making rotation more effortless and convenient, less prone to slippage, and improving the comfort and efficiency of height adjustment operation. The mounting groove 31 is connected to the axial cavity of the vertical tube 1, ensuring that the lead screw 33 can smoothly pass through the inner cavity of the vertical tube 1 and cooperate with the pin hole 34 of the vertical rod 2, ensuring smooth connection of all components of the fixing assembly 3 and realizing the normal operation of the height adjustment function. The limiting groove 37 cooperates with the limiting block 38 to restrict the movement trajectory of the lead screw 33 and prevent the lead screw 3 from moving. 3. During rotation, if there is any deviation or shaking, the screw 33 and the solenoid 32 are stably engaged, improving the accuracy and reliability of height adjustment. The arc design of the locking nut 45 allows it to fit tightly against the surface of the vertical tube 1, providing greater friction when tightening the nut to fix the support rod 43, enhancing the fixing effect and preventing the support rod 43 from loosening. The design of the mounting hole facilitates the bolts to firmly connect the device to the mine ground, further enhancing the stability of the positioning device and ensuring the accuracy of measurement work. The handles and anti-slip textures on both sides of the locking nut 45 make it easy for workers to quickly tighten the locking nut 45 and adjust the position of the support rod 43, improving the convenience and efficiency of operating the folding positioning component 4.

[0033] The working principle of this utility model is as follows: The support rod 43 is pulled out of the fitting groove 41, and its angle is adjusted according to the terrain. Then, the locking nut 45 is tightened to move it along the screw rod 44 and press against the vertical tube 1, fixing the position of the support rod 43. Next, the angle of the fixing plate 46 is adjusted so that it contacts the surface of the mine. The ore on the mine is then used to press the fixing plate 46 for simple positioning. Finally, the device is connected to the mine surface using bolts through the mounting holes on the fixing plate 46. Height adjustment is achieved by rotating the turntable. The moving bevel gear ring 36 drives the screw tube 32 to rotate via the bevel gear 35, causing the lead screw 33 to move within the screw tube 32. When the lead screw 33 is inserted into the pin hole 34 of the vertical rod 2, the height of the vertical rod 2 can be fixed. If the height needs to be adjusted, the driving bevel gear ring 36 is rotated in the opposite direction to disengage the lead screw 33 from the pin hole 34. After the vertical rod 2 slides up and down to the appropriate position, the driving bevel gear ring 36 is rotated again to fix the vertical rod 2. After the device is used, the locking nut 45 is loosened and the support rod 43 is retracted into the fitting groove 41 for easy transfer and storage.
