Description

Technical Field

[0001] The invention relates to the technical field of inclined shaft surrounding rocks, and in particular to a surrounding rock control device for construction of a gentle slope inclined shaft under a complex environment. Background Art

[0002] A deviated well refers to a well with an inclined angle in a drilling project. The wellhead and the designed target point are not on the same plumb line, but deviate from the wellhead vertical line by a certain distance in a given direction according to human needs.

[0003] When the inclined shaft is under construction, the soft terrain is prone to collapse. In order to avoid collapse, the inner wall of the inclined shaft will be reinforced. This practice is generally called surrounding rock;

[0004] The common practice is to implant rivets into the interior of the inclined shaft, hang net cables between the rivets, and pour concrete at the location of the protective net to form a support surface to prevent the inclined shaft from collapsing. This is what the industry calls "anchor net cable spraying."

[0005] The Chinese patent publication number: CN 112593942 A published an invention patent entitled "A deep well soft rock blind inclined well surrounding rock control device and implementation method", which includes a cableway system, a hollow grouting platform and a concrete preparation and transportation system;

[0006] It realizes the rapid semi-automatic control of the surrounding rock of deep soft rock blind inclined shafts, increases the overall support strength of the inclined shaft, achieves uniform modification of the tunnel surrounding rock, avoids blind spots in surrounding rock control, effectively improves the surrounding rock control efficiency, ensures the connection between mining and excavation in the mine, and can both speed up the support efficiency and improve the integrity of the surrounding rock of the blind inclined shaft.

[0007] The main technical solution of the above-mentioned prior art is to transport the hollow grouting platform by cableway to pour concrete in the inclined shaft. There is no problem in using the above method in a relatively regular inclined shaft. However, the excavation and construction of the inclined shaft are often diverted according to the terrain and actual needs, which leads to a relatively complex environment in the inclined shaft. If the above-mentioned prior art is used for construction in a complex environment, the hollow grouting platform cannot remain parallel to the wall of the inclined shaft, resulting in the inability of the prior art to produce the corresponding effect.

[0008] Therefore, a surrounding rock control device for gently sloping inclined shaft construction in a complex environment is provided, which is used for uniform pouring in a complex inclined shaft environment. Summary of the invention

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] See also Figure 1-10 , a surrounding rock control device for construction of a gently sloping inclined shaft in a complex environment, comprising a bearing mechanism 1, a concrete pouring mechanism 2 and an angle adjustment mechanism 3, the concrete pouring mechanism 2 is erected inside the bearing mechanism 1, the angle adjustment mechanism 3 is symmetrically installed on the concrete pouring mechanism 2, the bearing mechanism 1 is placed on the track of the inclined shaft, and the bearing mechanism 1 is towed by a tractor. In order to facilitate the transportation of materials, minerals and other items, tracks are laid in the inclined shaft for transportation by rail vehicles. Therefore, in a complex inclined shaft, the tracks can all operate well. This solution is based on real-time operation of the tracks that can operate;

[0047] The concrete pouring mechanism 2 comprises a concrete pouring box 201, wherein the interior of the concrete pouring box 201 is divided into a concrete transmission compartment 202 and an electrical equipment compartment 203, wherein the concrete transmission compartment 202 is used for conveying concrete, and the electrical equipment compartment 203 is used for installing a circuit control panel, a conveying pump and a hydraulic controller. A concrete inlet 204 is provided at the top of one side of the concrete pouring box 201, which is used to enable a concrete mixer truck to directly convey concrete to the interior of the concrete transmission compartment 202. During use, the device and the concrete mixer truck work synchronously to increase the efficiency of concrete pouring;

[0048] The electrical equipment compartment 203 is provided with circuit components, a delivery pump and a hydraulic control device, which is the control part of the equipment. The circuit components are used for logic control, the delivery pump is used for delivering concrete and pressurizing the concrete, so that the concrete can be poured onto the wall of the inclined shaft at a high speed, and the hydraulic control device is used to control the angle of the overall structure of the angle adjustment mechanism 3, so as to adjust the angle and distance of concrete pouring according to the complex position of the wall of the inclined shaft;

[0049] A vertical metal pipe 206 is fixedly connected to the top of the concrete pouring box 201. A symmetrically distributed shunt pipe 207 is arranged on the top of the vertical metal pipe 206. The vertical metal pipe 206 and the shunt pipe 207 cooperate with each other, so that concrete can be transferred to the mutually symmetrical angle adjustment mechanism 3 to realize synchronous pouring on both sides. A two-way guide pipe 205 extends from the bottom of the vertical metal pipe 206. One end of the guide pipe 205 is interconnected with the concrete inlet 204, and the other end of the guide pipe 205 is connected to the internal delivery pump of the electrical equipment compartment 203. When concrete enters the guide pipe 205 from the concrete inlet 204, the delivery pump on the other side of the guide pipe 205 pressurizes the concrete, so that the concrete can be pressed into the vertical metal pipe 206. The specific structure of the guide pipe 205 should be adjusted according to the type of delivery pump.

[0050] A control console 208 is fixedly connected to the top of the concrete pouring box 201. The control console 208 is connected to the circuit components, the delivery pump and the hydraulic control device inside the electrical equipment compartment 203. The circuit components, the delivery pump and the hydraulic control device are controlled by the control console 208. During use, the thickness of concrete pouring, the working logic of the delivery device and the angle adjustment mechanism 3 are pre-set through the control console 208.

[0051] A power socket 209 is provided on the side of the concrete pouring box 201 for convenient connection to a power source. When in use, it is generally powered by a power source configured on the tractor to improve the convenience of power supply. The power socket 209 is connected to an external power source to power the circuit components, delivery pumps and hydraulic control devices inside the electrical equipment compartment 203;

[0052] The angle adjustment mechanism 3 includes an active arm 301 and a hydraulic rod 304. One end of the active arm 301 is hinged to the side of the vertical metal pipe 206. The end of the active arm 301 is hinged to a driven arm 302. The end of the driven arm 302 is provided with a retractable telescopic head 303. The telescopic head 303 is set to be retractable. The purpose is to cope with complex inclined shaft environments and perform telescopic adjustments according to different positions of the inclined shaft wall.

[0053] The hydraulic rod 304 is located at the connection between the active boom 301 and the driven boom 302 and the connection between the active boom 301 and the vertical metal pipe 206, and both ends of the hydraulic rod 304 are hinged. The oil pipeline of the hydraulic rod 304 extends to the inside of the electrical equipment compartment 203 and is connected to the hydraulic control device. All hydraulic rods 304 are controlled individually, so that the active boom 301 and the driven boom 302 on both sides can complete more actions to cope with complex inclined well environments;

[0054] A concrete pouring pipe 305 is fixedly connected to the active arm 301 and the driven arm 302. One end of the concrete pouring pipe 305 is connected to the shunt pipe 207, and the other end of the concrete pouring pipe 305 extends to the end of the telescopic head 303. The concrete pouring pipe 305 is used to transport concrete to the wall of the inclined shaft. The concrete pouring pipe 305 is provided with a bellows joint 306 at the connection between the active arm 301 and the driven arm 302. The bellows joint 306 is used to change the angle of the concrete pouring pipe 305 by deformation when the angle of the connection between the active arm 301 and the driven arm 302 changes, so as to avoid the cross section of the concrete pouring pipe 305 being flattened when the angle of the active arm 301 and the driven arm 302 changes, resulting in the inability to transport concrete.

[0055] An infrared ranging probe 307 is installed on the top of the telescopic head 303, and the power line of the infrared ranging probe 307 extends to the circuit components inside the electrical equipment compartment 203;

[0056] The infrared distance measuring probe 307 is an important part of realizing intelligent control. The infrared distance measuring probe 307 can be set to a variety of logics. Two logics are provided below for reference:

[0057] Logic 1: Set the infrared distance measuring probe 307 to a constant value, that is, the position of the infrared distance measuring probe 307 does not change. When concrete is being poured, the distance between the infrared distance measuring probe 307 and the wall of the inclined shaft decreases due to the increase of concrete. When the distance is less than the threshold, the infrared distance measuring probe 307 sends a command signal to the control console 208 to let the hydraulic controller drive the active arm 301 and the driven arm 302 to change the angle for pouring or stop the delivery pump. In this way, the outer surface of the concrete pouring can be flat, but the disadvantage is that the thickness of the concrete inside floats with the wall of the inclined shaft. In simple terms, the thickness of the concrete inside is inconsistent.

[0058] Logic 2: Set the infrared ranging probe 307 to a floating value, that is, the infrared ranging probe 307 is extended and retracted through the telescopic head 303, so that the initial distance between the infrared ranging probe 307 and the wall of the inclined shaft remains unchanged, and the thickness of the poured concrete is set. When the pouring thickness is reached, the infrared ranging probe 307 sends a signal to change the position of the concrete pouring or stop conveying concrete, so that uniform pouring of concrete can be achieved. However, the disadvantage is that the outer surface after pouring may change according to the potholes on the wall of the inclined shaft, and manual leveling is required at the later stage.

[0059] Through the above technical solution, the bearing mechanism 1 is arranged on the track of the inclined shaft and is driven by the tractor to move. While moving, the concrete mixer delivers concrete to the interior of the concrete pouring box 201 through the concrete inlet 204, and then the concrete is transmitted through the delivery pump, and then sprayed to the wall of the inclined shaft through the concrete pouring pipe 305 connected to the active expansion arm 301 and the driven expansion arm 302, and the active expansion arm 301 and the driven expansion arm 302 are driven by the hydraulic rod 304 to achieve variable direction, and the telescopic head 303 changes the distance with the wall of the inclined shaft by telescoping, and detects the thickness of the concrete through the infrared ranging probe 307, so as to achieve the effect of being applicable to surrounding rock construction in complex environments;

[0060] An infrared distance measuring probe 307 is provided, so that by setting the thickness value between the infrared distance measuring probe 307 and the wall surface, when pouring concrete, when the thickness of the current area reaches the specified value, the infrared distance measuring probe 307 transmits a signal to the control console 208, and the control console 208 is used to change any one or more of the position of the end of the bellows joint 306, the start and stop of the delivery pump, and the telescopic length of the telescopic head 303, thereby achieving a high degree of intelligence;

[0061] The active arm 301 and the driven arm 302 are connected by hinges, and the lengths of the active arm 301, the driven arm 302 and the telescopic head 303 are set respectively. During transportation, the active arm 301 and the driven arm 302 can be folded by the hydraulic rod 304, thereby reducing the overall space occupied by the equipment and being able to easily enter an inclined shaft with a smaller opening.

[0062] Specifically, the concrete inlet 204 includes a material chute and a protective cover, and the protective cover is fixed on the top of the concrete pouring box 201 to cover the end of the material chute.

[0063] Through the above technical solution, the provision of a discharge chute can facilitate the concrete mixer truck to transport concrete into the concrete pouring box 201, and the provision of a protective cover is used to prevent concrete from splashing out and contaminating the top of the concrete pouring box 201 when transporting concrete.

[0064] Specifically, the vertical metal tube 206 is a metal tube with a hollow interior, and the diverter tube 207 directly passes through the interior of the vertical metal tube 206 .

[0065] Through the above technical solution, the interior of the vertical metal tube 206 is set to be hollow, so that the vertical metal tube 206 can be used directly as a pipeline without the need for an external pipeline to connect with the diversion tube 207.

[0066] Specifically, the control console 208 is located on one side of the top of the concrete pouring box 201 close to the traction hook 104 , and the control console 208 is provided with control buttons and a manual rocker.

[0067] Through the above technical solution, during use, the operator can directly control the equipment in the direction of the tractor. The function of the control button is to set the operating logic of the equipment, and the function of the manual joystick is to enable manual intervention of the equipment. When the situation in the inclined shaft is too complicated and the equipment cannot work autonomously, manual assistance is used to assist in construction.

[0068] Specifically, the length of the active arm 301 does not exceed the length of the vertical metal tube 206 , and the total length of the driven arm 302 and the telescopic head 303 does not exceed the length of the active arm 301 .

[0069] Through the above technical solution, the lengths of the active expansion arm 301, the driven expansion arm 302 and the telescopic head 303 are set, so that when not in use, the active expansion arm 301 and the driven expansion arm 302 can be folded by the hydraulic rod 304, thereby reducing the overall space occupied by the equipment, making it easier to enter an inclined shaft with a smaller opening and to facilitate transportation during transportation.

[0070] Specifically, the number of the driven extension arms 302 is at least one, and the telescopic head 303 is installed at the end of the topmost driven extension arm 302 .

[0071] Through the above technical solution, when the driven arm 302 is one section, only simple and limited actions can be achieved. When the number of the driven arm 302 increases, the movable parts will increase accordingly, so that more actions can be achieved, so as to achieve more accurate and diversified concrete pouring control.

[0072] Specifically, a guide cavity 3021 is provided inside the topmost driven extension arm 302 , and a telescopic oil cylinder 3022 is installed inside the guide cavity 3021 . The end of the telescopic oil cylinder 3022 pushes the telescopic head 303 to achieve telescoping.

[0073] Through the above technical solution, when in use, the telescopic head 303 can be driven to telescope by the telescopic cylinder 3022, so that the position of the end of the concrete pouring pipe 305 can be changed according to different pouring environments and plans. The concrete pouring pipe 305 is located at the connection between the driven expansion arm 302 and the telescopic head 303, which is also a bellows joint 306, so that the end of the concrete pouring pipe 305 can change with the telescopic head 303.

[0074] Specifically, the bearing mechanism 1 includes a supporting chassis 101, a protective frame 102 is fixedly connected to the top of the supporting chassis 101, a track wheel 103 is fixedly connected to the bottom of the supporting chassis 101, a towing hook 104 is provided at the end of the supporting chassis 101, and the towing hook 104 is connected to the towing vehicle.

[0075] Through the above technical scheme, the supporting chassis 101 is mainly used to bear the weight, just like the chassis of a car, and the protective frame 102 is mainly used to limit the concrete pouring box 201 to prevent the concrete pouring box 201 from displacement and protect the concrete pouring box 201. The track wheel 103 is a special wheel on the track, which is used to enable the entire device to run on the track, and the function of the traction hook 104 is to connect with the traction vehicle, and the traction vehicle is used to tow the entire equipment in the inclined shaft.

[0076] Specifically, both ends of the protection frame 102 are open, and the tops of the open ends of the protection frame 102 are fixedly connected with limiting parts 105, and the limiting parts 105 are triangular frames.

[0077] Through the above technical solution, the two ends of the protective frame 102 are set to be open, so that the concrete pouring box 201 can be easily installed without lifting the concrete pouring box 201 too high, and it is also convenient to connect the power cord. The set limit part 105 is used to limit the position of the concrete pouring box 201 to prevent the concrete pouring box 201 from sliding outward from the side of the protective frame 102.

[0078] Specifically, both ends of the concrete pouring box 201 are provided with limiting holes 210 , the height of the limiting holes 210 matches the top height of the limiting portion 105 , and the limiting holes 210 are threadedly connected with bolts, which cooperate with the limiting portion 105 to limit the concrete pouring box 201 .

[0079] Through the above technical solution, the concrete pouring box 201 and the protective frame 102 are connected in a detachable manner, and limiting parts 105 are set on both sides of the supporting chassis 101 to limit the concrete pouring box 201, and bolts are used to fix it to prevent the concrete pouring box 201 from moving up and down. During use, the concrete pouring box 201 can be easily separated from the protective frame 102 by removing the bolts, so as to achieve the effect of convenient maintenance and the use of the protective frame 102 alone. After the concrete pouring box 201 is removed, a truck bucket can be installed inside the protective frame 102 to transport materials.

[0080] When in use, the bearing mechanism 1 is placed on the track of the inclined shaft and is driven by the tractor to move. While moving, the concrete mixer truck delivers concrete to the interior of the concrete pouring box 201 through the concrete inlet 204, and then the concrete is transmitted by the delivery pump, and then sprayed to the wall of the inclined shaft through the concrete pouring pipe 305 connected to the active expansion arm 301 and the driven expansion arm 302. The active expansion arm 301 and the driven expansion arm 302 are both driven by the hydraulic rod 304 to achieve variable directions, and the telescopic head 303 changes the distance from the wall of the inclined shaft by telescoping, and detects the thickness of the concrete through the infrared ranging probe 307, so as to achieve the effect of being applicable to surrounding rock construction in complex environments;

[0081] By setting the infrared distance measuring probe 307, and setting the constant thickness between the infrared distance measuring probe 307 and the wall surface, when pouring concrete, when the thickness of the current area reaches the specified value, the infrared distance measuring probe 307 transmits a signal to the control console 208, and the control console 208 is used to change any one or more of the position of the end of the bellows joint 306, the start and stop of the delivery pump, and the telescopic length of the telescopic head 303, thereby achieving a high degree of intelligence.

[0082] The concrete pouring box 201 and the protection frame 102 are connected in a detachable manner, and the limiting parts 105 are provided on both sides of the supporting chassis 101 to limit the concrete pouring box 201, and bolts are used to fix them. During use, the concrete pouring box 201 can be separated from the protection frame 102, so as to achieve the effect of convenient maintenance and the protection frame 102 being used alone;

[0083] By connecting the active arm 301 and the driven arm 302 in a hinged manner, and setting the lengths of the active arm 301, the driven arm 302 and the telescopic head 303 respectively, the active arm 301 and the driven arm 302 can be folded by the hydraulic rod 304 during transportation, thereby reducing the overall space occupied by the equipment and being able to easily enter an inclined shaft with a smaller opening.

[0084] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
