Description

Technical Field

[0001] This invention relates to the field of measurement technology, and in particular to an automated measurement device for deep holes in mines. Background Technology

[0002] During underground mining, it is necessary to measure the depth of some medium-deep holes. The traditional method is to insert an iron wire into the bottom of the medium-deep hole and then pull the wire out to measure its length, or to use a tape measure to measure the depth. This method has practical problems such as large depth measurement error, low measurement efficiency, and inconvenience in carrying the tape measure.

[0003] The utility model patent CN222910000U solves the above problems by connecting multiple measuring rods of the same length to achieve depth measurement of medium and deep holes. It has high measurement accuracy and simplifies the measurement process. However, the above solution requires manual operation, which requires manual placement and deployment of the measuring rods one by one. It still has problems such as low operation efficiency and long time consumption. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an automated measurement device for deep holes in mines. This device can automatically mount and fix multiple measuring rods, enabling rapid and efficient measurement of deep holes in mines.

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0006] An automated deep-hole measuring device for mining includes a frame, multiple measuring rods, and an unwinding device. A limiting device is also provided at the bottom of the frame. A transfer locking device is provided between the limiting device and the unwinding device. The transfer locking device includes a vertically arranged drive shaft. A positioning rod is fixed to the side wall of the drive shaft. A positioning component for gripping the measuring rod is provided at the end of the positioning rod. The positioning component deflects directionally around the drive shaft. The unwinding device includes an unwinding roller and a rope. The bottom of the unwinding roller is fixedly connected to a first measuring rod. The unwinding roller is located on the deflection path of the positioning component. The positioning component includes at least three locking rollers arranged in a C-shape. The locking rollers are automatic force rollers. During the deflection of the locking rollers, the measuring rods are fitted onto the outer surface of the rope, controlling the two adjacent measuring rods to abut against each other. The locking rollers control the directional rotation of the top measuring rod, achieving locking and limiting of the two adjacent measuring rods.

[0007] Deep boreholes in mines are drilled to a depth of 5-50m and a diameter of 50-200mm. Precise measurement of borehole depth, diameter, and inclination parameters is required. The measuring rod is made of high-strength aluminum alloy, with a single length of 1-2m and a weight of ≤3kg, which facilitates automated transportation. Its surface is engraved with length scales.

[0008] The frame is a welded steel structure, 3-5m high, with leveling feet fixed at the bottom to ensure the equipment's levelness on complex mine terrain. The drive shaft is driven by a servo motor, which drives the positioning components to rotate directionally within a range of 0-180°; the positioning rod adopts a hollow steel tube structure to reduce weight while ensuring rigidity.

[0009] The locking roller has a built-in micro motor with a speed of 0-60 r / min and a C-shaped arrangement with a central angle of 120-150° to ensure stable gripping of the measuring rod. During rotation, the friction force drives the top measuring rod to rotate, so that the threads of adjacent measuring rods are precisely engaged. The locking torque is controlled at 5-10 N·m to avoid overtightening and damage to the threads.

[0010] The unwinding drum is made of high-strength nylon rope with a breaking strength of ≥500kg. The unwinding speed is synchronized with the splicing speed of the measuring rod to avoid rope slack or pulling.

[0011] The measuring rod here can be manually placed into the positioning assembly by the staff, or it can be manually placed through the automated vertical feeding structure to ensure continuous conveying of the measuring rod. The positioning assembly can be used to put the measuring rod on the outside of the rope, realizing continuous automatic conveying of the measuring rod without manual placement. During the placement of the measuring rod, the limiting device controls the downward movement of the measuring rod at the bottom to ensure that the rope is in a vertical and taut state, ensuring that the measuring rod can be properly placed on the outside of the rope.

[0012] By incorporating limiting devices and transfer locking devices, the measuring rod is gripped by a positioning component. Simultaneously, a drive shaft rotates the positioning component to automatically sleeve the measuring rod onto the outside of the rope, achieving automatic sleeve limiting. A locking roller controls the rotation of the measuring rod to lock and limit adjacent measuring rods, thus realizing continuous and automated limiting and fixing of the measuring rod. This equipment enables the automated sleeve and fixing of multiple measuring rods, achieving rapid and efficient measurement of deep holes in mines.

[0013] Preferably, an electrically controlled joint for opening and closing control is provided between multiple locking rollers, which controls the multiple locking rollers to unfold to form a larger space for placing the measuring rod; and controls the locking rollers to close together to reduce the space for gripping the measuring rod.

[0014] Preferably, the locking roller has expansion and contraction properties; controlling the expansion of the locking roller enables stable gripping of the measuring rod, and controlling the contraction of the locking roller enables placement of the measuring rod.

[0015] Preferably, the measuring rod has an upper thread and a lower thread, and the side of the measuring rod has a side opening for the rope to pass through.

[0016] After the two adjacent measuring rods are threaded and locked in place, the side openings of the side walls of the two adjacent measuring rods are staggered and alternately distributed to ensure that the two adjacent measuring rods can effectively limit the rope and prevent the rope from separating from multiple measuring rods, thus ensuring the stability of the medium-deep hole measurement process.

[0017] Preferably, it also includes a retractable clamping device, which is located above the positioning component, and the clamping device presses down to achieve abutting contact between two adjacent measuring rods.

[0018] The core function of the clamping device is to eliminate thread engagement gaps and ensure the straightness of the measuring rod after splicing. Its downward stroke is 10-20mm, and the downward pressure is controlled at 10-15N. Pressure is fed back by a pressure sensor, and the clamping stops when the set value is reached to prevent excessive pressure from damaging the threads. The clamping device works in conjunction with the positioning assembly. After the positioning assembly rotates the top measuring rod until the threads are initially engaged, the clamping device begins to press down, ensuring complete thread contact.

[0019] By setting the above structure, the measuring rod can be pressed down from above, thereby ensuring that two adjacent measuring rods are in a tight-fitting state before the threads are tightened. In preparation for the subsequent locking and fixing of the measuring rods, the continuous locking and limiting of multiple measuring rods can be achieved through the cooperation between multiple units.

[0020] Preferably, the clamping device includes a telescopic device, the telescopic end of which is fixed with a clamping rod, and the front end of the clamping rod is provided with a clamping ring, which is sleeved on the outside of the rope and located above the deflection path of the positioning component.

[0021] Preferably, the limiting device includes a limiting bracket and limiting rollers, and at least two sets of limiting rollers are provided along the vertical direction to complete the vertical limiting and conveying of the measuring rod.

[0022] Preferably, the positioning rod and positioning assembly are configured as two sets, and also include a misalignment structure located outside the rope, through which the rope is pushed to the outside of the rotation path of the locking roller.

[0023] During the use of the misalignment structure, the measuring rod is moved upward appropriately by the limiting device, or the unwinding drum is unwound appropriately to keep the rope in a relatively slack state. This prevents the misalignment structure from applying excessive pressure to the rope, which could cause the overall structure to misalign, and ensures the normal and stable operation of the overall structure.

[0024] The beneficial effects of this invention are as follows:

[0025] Compared with existing technologies, this device incorporates a limiting device and a transfer locking device. A positioning component grips the measuring rod, while a drive shaft rotates the positioning component to automatically sleeve the measuring rod onto the outside of the rope, achieving automatic sleeve limiting. A locking roller controls the rotation of the measuring rod to lock adjacent measuring rods, thus realizing continuous and automated limiting and fixing of the measuring rod. This device enables the automated sleeve and fixing of multiple measuring rods, achieving rapid and efficient measurement of deep holes in mines. Attached Figure Description

Detailed Implementation

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0037] To address the problems mentioned in the background art; see Appendix Figure 1 -Appendix Figure 9 An automated deep hole measuring device for mining includes a frame 100. The frame 100 is equipped with an unwinding device 300 and a transfer locking device 500. The unwinding device 300 completes the winding and unwinding of the rope 320, and the transfer locking device 500 completes the transportation of the measuring rod 400, thereby realizing automated measurement of deep holes.

[0038] To enable automated measurement of medium-deep holes, the frame 100 includes a base plate 110, a support frame 120, and a top plate 130. Both the top plate 130 and the base plate 110 have openings. The opening in the top plate 130 is used to place the measuring rod 400, and the opening in the base plate 110 allows the measuring rod 400 to pass through for measurement. Rollers are installed at the bottom of the frame 100 for easy transportation.

[0039] An unwinding device 300 is provided on the upper part of the frame 100. The unwinding device 300 consists of an unwinding roller 310 and a rope 320. The unwinding roller 310 can realize the unwinding and rewinding of the rope 320. During the measurement process, the unwinding roller 310 is controlled to unwind, and the rope 320 gradually becomes longer to realize the measurement of the medium-deep hole. During the rewinding process, the rope 320 is used to lift multiple measuring rods 400 to realize the recycling of the measuring rods 400.

[0040] A transfer locking device 500 is provided at the lower end of the measuring rod 400. The transfer locking device 500 transports the measuring rod 400 to a designated point and fixes it relative to the rope 320 for measurement. Here, fixing means that the measuring rod 400 is sleeved on the outer surface of the rope 320, thereby ensuring that the movement of the two is relatively consistent, realizing effective measurement control of multiple measuring rods 400 and facilitating subsequent stable winding and retrieval.

[0041] Specifically, the transfer locking device 500 includes a drive shaft 530 fixed in the middle, a positioning ring 540 sleeved on the outside of the drive shaft 530, a positioning rod 520 connected to the positioning ring 540, and a positioning component 510 at the front end of the positioning rod 520. The positioning component 510 locks the measuring rod 400 and rotates it under the action of the drive shaft 530. The positioning rod 520 drives the measuring rod 400 inside the positioning component 510 to deflect to one side of the rope 320, and finally the measuring rod 400 is sleeved on the outside of the rope 320, completing the sleeve fixing.

[0042] The positioning assembly 510 here can consist of three locking rollers 511. One locking roller 511 is fixed to the positioning rod 520, and the other two locking rollers 511 form a C-shape with it to firmly lock the measuring rod 400.

[0043] The locking rollers 511 can be implemented in various ways. An electrically controlled joint for opening and closing can be set between multiple locking rollers 511 to control the multiple locking rollers 511 to expand and create a larger space for placing the measuring rod 400, and to control the locking rollers 511 to close and reduce the space for stable gripping of the measuring rod 400. Similarly, the locking rollers 511 can also be selected to have expansion and contraction characteristics, such as an air bladder connected to a pump structure on the surface or inside. By controlling the expansion of the air bladder, the measuring rod 400 can be stably gripped, and by controlling the contraction of the air bladder, the measuring rod 400 can be placed.

[0044] To further achieve automated measurement, please refer to the appendix for details. Figure 7 A limiting device 200 is installed at the opening of the base plate 110. The limiting device 200 consists of a limiting bracket 210 and a limiting roller 220. The limiting roller 220 is divided into upper and lower pairs. During measurement, the measuring rod 400 passes through the limiting roller 220 and slowly moves down under the action of the drive to perform the measurement.

[0045] The limiting roller 220 can not only clamp the measuring rod 400 for downward or upward transport, enabling the placement, measurement, and retrieval of the measuring rod 400, but also fix the measuring rod 400 located at the bottom, facilitating stable temporary fixation between the upper and lower sections of the measuring rod 400 and ensuring stability during subsequent measurement processes.

[0046] During measurement, the measuring device is transported above the medium-deep hole to be measured, aligning the hole in the base plate 110 with the measuring hole. The measuring rod 400 falls into the C-shaped locking roller 511 of the transfer locking device 500 and is locked in place. It is then transferred to the unwinding device 300 via the drive shaft 530. The measuring rod 400 is then passed through the rope 320, placing it in the sleeve limit position. After temporary locking between two adjacent measuring rods 400, it moves down to the limit device 200 and passes through the limit roller 220 to await the next measuring rod 400. The above steps are repeated to achieve continuous automatic fixing of multiple measuring rods 400 without manual intervention, greatly improving the efficiency of medium-deep hole measurement.

[0047] The measuring rod 400 here is provided with an upper thread 410 and a lower thread 420. The upper thread 410 and the lower thread 420 can mesh and abut against each other. The side of the measuring rod 400 has a side opening 430 to facilitate the passage of the rope 320.

[0048] After the first measuring rod 400 and rope 320 are lowered to the limiting roller 220, the rope 320 is in a taut state. The transfer locking device 500 transports the measuring rod 400 to the measuring position again in the same way, puts it into the taut rope 320, and then presses it against the measuring rod 400 below. Under the action of the limiting device 200, it moves downward. The above operation is repeated to complete the medium-deep hole measurement.

[0049] The locking roller 511 here is an automatic force structure that allows the measuring rod 400 to rotate around its own axis. It controls the upper and lower measuring rods 400 to abut against each other and controls the measuring rod 400 at the bottom to be in a relatively fixed state through the limiting device 200. During the rotation of the upper measuring rod 400, the upper and lower measuring rods 400 are locked together to achieve temporary locking and fixation.

[0050] It should also be noted that the positioning rod 520, positioning component 510 and other structures can be selected from the two sets shown in the attached figure. In this case, after the measuring rod 400 is sleeved on the outside of the rope 320, a misalignment structure is needed to push the rope 320 to the outside of the rotation path of the locking roller 511, so as to ensure the continuous deflection of the two positioning rods 520 and positioning component 510 to realize the continuous gripping and conveying of multiple measuring rods 400.

[0051] Alternatively, a single positioning component 510, positioning rod 520, or other structures can be selected. In this case, the positioning component 510 and positioning rod 520 are selected as reciprocating swing structures. After the first measuring rod 400 is temporarily fixed, it reverses and resets along the original path to achieve the gripping, fixing, and conveying of subsequent measuring rods 400.

[0052] To further improve the clamping of the upper and lower measuring rods 400, a clamping device 600 is provided above the positioning ring 540. The clamping device 600 includes a telescopic device 610, which is sleeved on the outside of the drive shaft 530. The telescopic device 610 is connected to the clamping rod 620, and a clamping ring 630 is provided at the front end of the clamping rod 620.

[0053] When the measuring rod 400 is transferred to the measuring position and the rope 320 is inserted, the tensioning ring 630 is driven by the telescopic device 610 to push the measuring rod 400 down to abut against the measuring rod 400 below, ensuring that the two measuring rods 400 are in abutting state during the rotation thread locking process, thus ensuring the stability of the screw locking.

[0054] In summary, through the above structural design, the measuring rod 400 is automatically transported under the action of the transfer locking device 500 and connected to the rope 320. The unwinding device 300 realizes the automatic winding and unwinding of the rope 320, and the limiting device 200 controls the measuring rod 400 to be pressed up and down and slowly moved down, thereby realizing the automated measurement of medium and deep holes.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
