Description

Technical Field

[0001] The invention belongs to the technical field of coal mine detection, and in particular relates to a pushing device and method for a mine drilling peep rod. Background Art

[0002] In many fields, such as coal mining and geological exploration, borehole peeping technology is widely used to obtain information about the interior of the borehole. Existing borehole peeping operations often rely on manual pushing of the peeping rod into the borehole. Due to the limitations of manual operation, it is difficult to maintain a uniform pushing speed during the pushing process. Uneven speed can lead to a decrease in the peeping instrument's imaging quality, affecting the judgment of the borehole's internal conditions. Furthermore, manual operation is labor-intensive and inefficient, and pushing the peeping probe can easily cause it to be bumped. This makes it difficult to meet the requirements of efficient and safe operations in scenarios requiring extensive borehole peeping work.

[0003] Therefore, it is necessary to provide an improved technical solution to the above-mentioned deficiencies in the prior art. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art. The present invention provides a pushing device and method for a mining drilling peep rod.

They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention. The terms "connected" and "connected" used in the present invention should be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be a direct connection or an indirect connection through an intermediate component. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0033] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

[0034] like Figure 1-5 As shown, a pushing device for a drilling peep rod for mining includes a bracket 2, a pushing mechanism, and a loading turntable 6. The bracket 2 is a three-legged retractable bracket 2 that can quickly adjust the height and support area according to the tunnel space. Combined with the lightweight design and the stabilizing connecting rod 5 structure, it can not only ensure stability during operation, but also enhance the portability of the device. It is particularly suitable for narrow or underground environments with complex geological conditions. A rising disk 1 is fixed on the bracket 2 by bolts. The middle part of the rising disk 1 is provided with a rod outlet hole corresponding to the push rod 3. The diameter of the rod outlet hole is slightly larger than the push rod 3. The rising disk 1 is a hollow shell structure, specifically including a columnar shell and upper and lower end plates. The rod outlet hole is provided in the center of the upper and lower end plates, so that the pushing mechanism can be set in the rising disk 1. The pushing mechanism has a pushing component corresponding to the push rod 3, so that the push rod 3 can be pushed upward.

[0035] The loading turntable 6 is located on the base 7 below the rising plate 1. The base 7 is disc-shaped. A plurality of push rods 3 are provided on the loading turntable 6. A plurality of assembly holes corresponding to the push rods 3 are provided at the upper end of the loading turntable 6 for fixing the push rods 3. A secondary pushing mechanism 14 corresponding to the push rod 3 is provided in each assembly hole.

[0036] The secondary pushing mechanism 14 is located at the bottom of the assembly hole. A push plate corresponding to the push rod 3 is provided at the upper end of the secondary pushing mechanism 14. The secondary pushing mechanism 14 can be an electric push rod, a cylinder or a hydraulic cylinder, thereby driving the push rod 3 axially upward along the assembly hole under the action of an external power source.

[0037] Furthermore, the secondary pushing mechanism 14 can be a piston plate in which a piston is assembled in an assembly hole, and air is supplied to the bottom of the piston plate so that the piston plate slides upward and pushes up the pushing rod 3.

[0038] In this embodiment, the screwing mechanism is arranged between the loading turntable 6 and the base 7 to drive the loading turntable 6 to rotate. The loading turntable 6 is similar to a revolver drum, and multiple push rods 3 on the loading turntable 6 can be pushed in sequence by rotating it easily.

[0039] Generally, the two ends of the push rod 3 are respectively a threaded portion and a screw sleeve portion, and adjacent push rods 3 are butted together in the form of threaded assembly. In order to achieve butt connection between the two adjacent push rods 3 in the pushing process,

[0040] The aperture of the assembly hole is larger than the outer diameter of the push rod 3, so as to make room for the tilt caused by rotation. An elastic clamping part corresponding to the clamping of the push rod 3 is provided at the opening of the assembly hole. Preferably, a stepped platform with an increased inner diameter is provided at the opening of the assembly hole for assembling the elastic clamping part, so that the shallow hole assembly design of the elastic clamping part supports the simultaneous loading and rapid recovery of multiple push rods 3, thereby significantly improving the working efficiency.

[0041] When the upper push rod 3 has not completely passed through the pushing mechanism upward, the next push rod 3 is pushed. Generally speaking, when the lower end of the upper push rod 3 and the upper end of the next push rod 3 are at the same height, the screwing mechanism drives the next push rod 3 into place. After the two push rods 3 are made to collide with each other through the secondary pushing mechanism 14, the screwing mechanism continues to drive the loading turntable 6 to rotate while the secondary pushing mechanism 14 synchronously lifts the next push rod 3. At this time, the upper push rod 3 is clamped by the pushing roller 4 and will not rotate. Under the clamping of the elastic clamping part, the next push rod 3 can rotate relative to the upper push rod 3, so that the threaded connection part of the push rod 3 can be docked. After the docking is completed, the screwing mechanism stops rotating until the next push rod 3 is completely out of the assembly hole.

[0042] In an optional embodiment, the main body of the screwing mechanism is a base 7, and a rotating shaft 13 is rotatably connected above the base 7. The upper half of the rotating shaft 13 is a hexagonal structure and is concentrically assembled with the loading turntable 6. A hexagonal hole corresponding to the rotating shaft 13 is provided in the middle of the loading turntable 6. The screwing mechanism can be pneumatically or electrically driven, such as an air motor. The air motor is correspondingly assembled at the bottom of the base 7 and correspondingly connected to the rotating shaft 13, so that the loading turntable 6 can be driven.

[0043] In this case, the secondary pushing mechanism 14 is preferably a gas cylinder or piston plate. The secondary pushing mechanism 14 and the screwing mechanism are connected to a gas cylinder 8 or a gas pedal via connecting valves, respectively, which serves as the power source to drive the push rod 3. The use of gas power eliminates the need for an external power source, fundamentally eliminating the risk of electrical leakage, fire, or explosion caused by electrical equipment in humid, gassy mines. Furthermore, the combination of the dual rubber wheel clamp and the flexible fixture can accommodate push rods 3 of varying diameters, surface roughness, and slight deformation, ensuring clamping stability and reducing the risk of slippage or loosening.

[0044] Furthermore, the pushing mechanism includes a pushing roller 4 and a rotating handle. The two pushing rollers 4 are respectively located on both sides of the rod hole. The rotating shafts 13 of the two pushing rollers 4 are rotatably connected to the side wall of the rising plate 1. The main shaft of one of the pushing rollers 4 extends out of the rising plate 1 and is connected to the rotating handle. The rotating handle can also be replaced with a corresponding pneumatic motor, and the pneumatic motor is correspondingly connected to the gas cylinder 8 to achieve drive.

[0045] Furthermore, the side wall of the rising plate 1 corresponds to a horizontally extending strip hole of the push roller 4 that is not connected to the rotating handle, so that the push roller 4 is slidably assembled. A traction spring 9 is provided between the two ends of the main shaft of the two push rollers 4. The two ends of the traction spring 9 are respectively rotated through the rotating sleeve 10 to connect the main shaft of the two push rollers 4, thereby ensuring the clamping of the push rod 3, so that the friction force after clamping with the push rod 3 is greater than the friction force between the elastic clamping part and the push rod 3.

[0046] An anti-skid rubber layer is attached to the outer wall of the pushing roller 4 to ensure the anti-skid effect of the pushing roller 4 and improve the pushing stability.

[0047] In an optional embodiment, a stabilizing link 5 corresponding to the base 7 is provided in the middle of the bracket 2. The stabilizing link 5 corresponds to the edge of the base 7 and can be a steel pipe to ensure stability during the pushing process.

[0048] The elastic clamping part includes a flexible belt 15 and an elastic part 11. The flexible belt 15 is a strip of rubber and can be wrapped around the outer wall of the push rod 3 by deformation. The elastic part 11 is fixed to the outer wall of the flexible belt 15 to elastically support between the inner wall of the assembly hole and the flexible belt 15, so that the push rod 3 can be tilted, thereby achieving the purpose of tightening the threaded connection between two adjacent push rods 3.

[0049] In this embodiment, the elastic member 11 is an arc-shaped structure, the two ends of the arc-shaped structure are supported on the inner wall of the assembly hole or the step, the middle part is fixed to the outside of the flexible belt 15, and multiple elastic members 11 are evenly distributed circumferentially of the push rod 3, or multiple elastic members 11 are distributed side by side in the length direction of the flexible belt 15, and the middle part of the elastic member 11 is fixed to the outer wall of the flexible belt 15, thereby forming a stable support relationship in the circumferential direction.

[0050] Furthermore, a retaining ring 12 is threadedly assembled on the hole of the step platform for the elastic part 11. The inner diameter of the retaining ring 12 is larger than the push rod 3, thereby preventing the elastic clamping part from moving upward during the pushing process, and allowing the elastic clamping part to slide axially on the push rod 3, thereby ensuring that the clamping requirements are met when the push rod 3 is clamped, and avoiding clamping failure caused by the elastic clamping part falling off during the pushing process.

[0051] The elastic member 11 can be made of any one of a metal spring, a rubber material or a polypropylene material. The elasticity and material of the elastic member 11 are selected according to actual needs.

[0052] In an optional embodiment, the support legs of the bracket 2 can be telescopic rods, and the height of the bracket 2 and the rising plate 1 are installed according to the length of the pushing rod 3, so that the distance between the upper end of the pushing rod 3 assembled on the loading turntable 6 and the lower surface of the rising plate 1 is smaller than the pushing stroke of the secondary pushing mechanism 14, and there is a distance of not less than 15 cm between the pushing roller 4 and the lower surface of the rising plate 1, thereby ensuring that the secondary pushing mechanism 14 can effectively push.

[0053] This application also provides a pushing method for a mining drilling peep rod. First, open the bracket 2, assemble the bracket 2 and the rising plate 1 directly below the drill hole, so that the rod outlet hole in the middle of the rising plate 1 is opposite the drill hole, and the aperture of the rod outlet hole is slightly larger than the pushing rod 3; the power source and the pushing mechanism, the screwing mechanism, and the secondary pushing mechanism 14 are stably connected, and multiple pushing rods 3 are placed in the assembly holes at the upper end of the loading turntable 6, and then moved and placed under the rising plate 1, so that the rising plate 1 and the loading turntable 6 are concentrically distributed, and then the bracket 2 and the base 7 are stably connected through the stabilizing connecting rod 5.

[0054] The pushing mechanism is debugged, and the pushing rod 3 is pushed to the rod outlet hole through the secondary pushing mechanism 14 in one of the assembly holes, and is continuously pushed into between the two pushing rollers 4 of the pushing mechanism, and the first pushing rod 3 is pushed to the drill hole using the pushing mechanism.

[0055] After the lower end of the first pushing rod 3 is at the same height as the lower surface of the rising disk 1, it is considered that the pushing of the pushing rod 3 is completed. Then, the screwing mechanism under the loading and feeding turntable 6 is driven to rotate, so that the next pushing rod 3 is aligned with the previous pushing rod 3, and the secondary pushing mechanism 14 is used to make the next pushing rod 3 touch the lower end of the previous pushing rod 3. Then, during the pushing process of the secondary pushing mechanism 14, the screwing mechanism continues to drive the loading and feeding turntable 6 to rotate, so that the next pushing rod 3 and the previous pushing rod 3 are threadedly connected during the pushing process. After the docking is completed, the secondary pushing mechanism 14 stops driving, and the pushing mechanism continues to push the pushing rod 3 upward, thereby repeatedly pushing multiple pushing rods 3 on the loading and feeding turntable 6 into the drill hole in turn, realizing automatic connection and continuous lifting of the pushing rod 3, avoiding the intermittent pause problem caused by the reciprocating motion in the prior art, significantly shortening the pushing cycle, and meeting the requirements of high-intensity continuous operation.

[0056] The secondary lifting device of the push rod 3 is lowered to its original position, and a new push rod 3 can be installed. A step with an increased inner diameter is set at the mouth of the assembly hole, and an elastic clamping part is installed in the step. After the push rod 3 is clamped, a stop ring is installed on the thread along the step.

[0057] In an optional embodiment, there are 4 or 6 assembly holes. When the secondary lifting device is driven by the gas cylinder 8, the secondary lifting device in each assembly hole is connected to the gas cylinder 8 through a control valve and an independent hose. During the rotation process, each hose can be wrapped around the outer wall of the loading turntable 6. After a pushing rod 3 completes the pushing, the loading turntable 6 rotates and resets.

[0058] Furthermore, a plurality of automatic reeling discs corresponding to a plurality of hoses may be provided to roll up the hoses, thereby preventing the hoses from being entangled with each other during the rotation of the loading and delivering turntable 6 .
