Description

Technical Field

[0001] The invention relates to the technical field of inclined shaft excavation equipment, and in particular to large-angle inclined shaft expansion and slag removal construction equipment and a construction method. Background Art

[0002] At present, with the in-depth promotion of the national "carbon peak and carbon neutrality" strategy, the country's demand for clean energy is increasing. The scale of pumped storage installed capacity in my country is far lower than the national plan. Pumped storage power stations and conventional hydropower stations generally use underground tunnels to divert water. Due to the need for concentrated head, the head and end of the water diversion tunnel have a large height difference, and an inclined shaft needs to be set up. The water diversion inclined shaft generally consists of an upper curved section, an inclined straight section, and a lower curved section. Due to the large inclination of the tunnel, the traditional shield method and trolley drilling and blasting method cannot meet the on-site excavation requirements. Such a multifunctional inclined shaft excavation trolley came into being. The excavation of the inclined straight section first requires drilling and blasting of the tunnel face, and then slag cleaning. The equipment needs to have mechanized construction of multiple processes such as drilling, slag removal, and anchoring.

[0003] A Chinese patent with application number CN202320547692.6 discloses a comprehensive trolley for inclined shaft construction. Through an excavation device, a slag removal device and a support platform, multiple processes can be constructed on the inclined shaft at the same time, reducing the time used to replace equipment and improving production efficiency. The anti-skid device can be used to perform emergency braking on the comprehensive trolley for inclined shaft construction to prevent the comprehensive trolley for inclined shaft construction from moving forward rapidly when the wire rope or the support device fails, thereby damaging the comprehensive trolley for inclined shaft construction and causing casualties. The position of the rock drill rig is adjusted by the support arm, the rotary drive, the first telescopic drive and the second telescopic drive so that the rock drill rig can drill the entire wedge.

[0004] The Chinese patent application number CN202123014297.1 discloses an integrated platform device for inclined shaft expansion, drilling and slag removal. In this application, a telescopic arm is used to control the extension and retraction of the slag removal mechanism, and a slewing mechanism is used to control the rotation of the slag removal mechanism. When removing slag, the slag removal mechanism can rotate 360 ​​degrees around the rotation axis. The slag removal range covers the entire working surface, ensuring that there are no dead angles for slag removal. It overcomes the problems of low construction efficiency, high labor intensity, time-consuming and labor-intensive, and prominent safety issues, and realizes the modernization of inclined shaft construction equipment, replacing manual labor with machinery, reducing the demand for manpower on high-risk working surfaces, reducing safety management risks, and shortening construction time. However, the following problems still exist in actual applications, specifically: 1. The slag cleaning after large-angle inclined shaft excavation and blasting is generally done by excavators in combination with manual cleaning. The excavator has a small operating range, and below the slag accumulation, the excavator can only use the bucket to dig out the slag first, and then move the boom to make the bucket near the slag chute and unload the bucket. During this period, the excavator needs to be moved to clean the slag at various locations. Manual cooperation also has the problems of low efficiency and high labor intensity. Now, an efficient slag cleaning process is needed after large-angle inclined shaft excavation and blasting; 2. During the slag removal process, mud will adhere to the inside of the bucket, which needs to be cleaned manually, which is inefficient. At the same time, if it is not cleaned for a long time, the bucket will become bulky and difficult to clean manually. 3. Due to the unevenness of the wall of the inclined shaft, the blade will bear different forces during its operation. When encountering hard parts, the bucket may even deform. During the process of limiting and fixing the equipment, the legs may also be deformed to varying degrees due to uneven forces.

[0005] Therefore, the present invention provides a large-angle inclined shaft expansion and slag removal construction equipment and a construction method to solve the above problems. Summary of the invention

[0029] The above and other technical contents, features and effects of the present invention are described in detail below with reference to the attached Figures 1 to 12 The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the drawings in the specification.

[0030] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0031] The present invention is a large-angle inclined shaft expansion and slag removal construction equipment and a construction method, which comprises a frame 5 system, an artificial movable platform, a slide system, a rock drilling boom system, and a slag removal system 4.

[0032] The frame 5 system includes a frame 5, track walking wheels 6, multiple pulley blocks 7 for traction frame 5 movement, and legs 8 above the frame 5. The pulley block 7 is connected to the external winch lifting system through a wire rope, and the lower part of the wire rope is connected to the pulley block 7. According to the weight of the trolley, the pulley block 7 can be provided in multiple sets. The whole set of equipment can be moved on the track below the inclined shaft through this lifting system. The equipment expansion and slag removal equipment starts to work when it moves to the vicinity of the heading face. In order to improve the stability of the equipment during operation, the legs 8 are extended and supported on the rock surface of the tunnel to ensure the stability of the entire equipment. At the same time, the artificial movable platform is horizontally fixed on the frame 5, which is mainly used for the later grouting, grouting and other process operations of the tunnel wall after excavation.

[0033] The slide system is arranged inside the frame 5, and the slide system comprises a plurality of slideways 9, a slide, and a lifting cylinder. The slide moves under the action of the lifting cylinder. The rock drilling boom system is fixed on the slide, and the slide moves under the action of the lifting cylinder. When the rock drilling boom system is not working, the whole set of rock drilling boom can be hidden inside the frame. When rock drilling operation is required, the slide can move the whole set of rock drilling boom system to the bottom of the frame. The rock drilling boom system comprises a boom seat, and a swivel double boom is installed on the boom seat. The swivel double boom consists of three parts: a swivel arm, a right drilling arm and a left drilling arm. The swivel double boom is realized by the swivel arm. The rotation and extension of the boom, and the adjustment of the drilling position are achieved through the position adjustment of the left drilling arm and the right drilling arm. The rotation center of the slide is set on the center line of the tunnel. Under the rotation and extension of the slide and the movement combination of multiple groups of booms, the entire face drilling operation and the tunnel arm anchor hole drilling operation can be achieved. At the same time, the slewing arm includes a slewing boom, a slewing telescopic arm, a slewing reducer, a telescopic cylinder, etc. The rotation and extension of the slewing double-boom frame can be achieved through the above combination. The left drilling arm and the right drilling arm both include a boom, a telescopic arm, a slewing oil rod, a telescopic cylinder, a propulsion beam assembly, etc. The rotation, extension, pitch, swing and other movements of the propulsion beam can be achieved through the above combination.

[0034] The slag removal system 4 includes a boom basic section 12, a boom telescopic section 13 mounted on the boom basic section 12, the boom telescopic section 13 is connected to a telescopic hydraulic cylinder 14, and the boom telescopic section 13 is telescoped in the boom by the telescopic hydraulic cylinder 14. A slewing mechanism is installed on the boom telescopic section 13, and the slewing mechanism includes an inner ring 15 fixedly connected to the boom telescopic section 13, an outer ring 16 is connected to the inner ring 15, and an arm seat 17 is connected to the outer ring 16. The arm seat 17 rotates + / -180 degrees, ensuring that the slag removal process can be operated in a full range of + / -180 degrees, ensuring the operating range of the slag removal process equipment, and improving the operating efficiency and slag removal effect. A boom 18 is hinged on the arm seat 17, and a dipper 19 is hinged on the other end of the boom 18, and a dipper 22 is hinged on the other end of the dipper 19. The arm seat 17 and the boom 18 are connected There is a boom hydraulic cylinder 20, and a boom hydraulic cylinder 21 is hinged between the boom 19 and the boom 18. The boom 18 can be rotated around the hinge point by telescoping the boom hydraulic cylinder 20, and the boom 19 can be rotated around the hinge point by telescoping the boom hydraulic cylinder 21. A bucket hydraulic cylinder 50 is hinged on the bucket 19, and a bucket connecting rod 49 is hinged on the other end of the bucket hydraulic cylinder 50. The bucket connecting rod 49, the bucket 22, and the boom 19 form a four-bar mechanism. The rotation of the bucket 22 is achieved by telescoping the bucket hydraulic cylinder 50. The inclination angle of the bucket 22 and the slag removal position are adjusted by the coordinated cooperation of the telescopic hydraulic cylinder 14, the boom hydraulic cylinder 20 and the bucket hydraulic cylinder 50, thereby ensuring the efficiency and range accuracy of slag removal, being able to cover the range of crushed stone in all directions, and realizing the fully hydraulically precisely controlled gravel cleaning operation, which greatly improves the work efficiency and reduces the labor intensity of the workers.

[0035] During the specific implementation of this embodiment, during the specific use process, the lifting cylinder drives the slide system to slide inside the inclined shaft, and the steel wire rope and pulley block 7 drive the frame system to slide, thereby realizing the movement of the entire equipment, ensuring that the equipment can slide smoothly in the inclined shaft. At the same time, when the entire equipment slides to the working surface, the drilling operation is realized through the rock drilling boom system. After the drilling is completed, the equipment is evacuated, and explosives are installed for blasting. After the blasting ventilation, the slide system slides to the working surface, and then the slag removal operation is carried out. When the axial feed of the telescopic section 13 of the large arm enters the slag accumulation The slag is pushed into the slag chute by the arm seat 17, and the arm seat 17 can make a radial rotation of + / -180°, and the slag pushing operation of the slag working arm can be realized within a circumferential range of 360 degrees. The axial feed / retraction and radial rotation of the arm seat 17 can realize the slag from the upper layer to the lower layer, from the near slag chute entrance to the far slag chute entrance into the slag chute, so as to realize the slag operation in the inclined shaft. At the same time, the adjustment of the scraper bucket 22 is realized through the scraper bucket hydraulic cylinder 50, the scraper bucket connecting rod 49, the scraper bucket 22, the bucket arm 19 and other structures, so as to adapt to inclined shafts in different scenes and ranges, and at the same time ensure that the slag can better enter the interior of the scraper bucket 22.

[0036] In order to ensure the scraping efficiency of the bucket 22, and at the same time avoid the solid slag from causing damage to the bucket 22, avoid the slag on the face of the tunnel from being in hard contact with the bucket 22, resulting in deformation of the bucket 22, and inconvenience in the maintenance of the bucket 22 inside the inclined shaft, so this embodiment provides a method to avoid the problem of collision deformation caused by hard contact between the bucket 22 and the slag, so the bucket 22 includes the bucket 22, and the end of the bucket 22 away from the bucket rod 19 is provided with a sliding groove 23, the sliding groove 23 is fixedly connected to the limit sleeve 24, the limit sleeve 24 is slidably connected to the sliding plate 25, and the sliding plate 25 slides along the limit sleeve 24, thereby ensuring the removal of slag in the inclined shaft. The shaking during the slag removal process facilitates the handling of slag and avoids hard contact. A plurality of limiting holes 26 are provided at one end of the sliding plate 25 away from the limiting sleeve 24. A sliding column 27 is coaxially slidably connected inside the limiting hole 26. A scraper 28 is fixedly connected to the sliding column 27. The sliding column 27 and the limiting hole 26 are connected by a spring. Under the action of the sliding column 27 and the spring, the scraper 28 can slide along the axial direction of the limiting hole 26. When the scraper 28 encounters a hard object, the scraper 28 can shrink to one side of the limiting hole 26 to avoid hard contact and damage to the scraper 28.

[0037] In order to realize the shaking of the scraper 28, it is necessary to drive the sliding plate 25. Therefore, the sliding plate 25 is fixedly connected with a circular groove 29 near one end of the bucket 19. The circular groove 29 has a built-in limit pin. The limit pin is eccentrically connected with a cam plate 31. The cam plate 31 is fixedly connected to a driving telescopic rod 32 connected to the inside of the scraper bucket 22. The driving telescopic rod 32 is connected to a micro motor placed inside the scraper bucket 22. The micro motor drives the driving telescopic rod 32 to rotate. The rotation of the driving telescopic rod 32 drives the cam plate 31 to rotate. During the rotation process of the cam plate 31, due to the cooperation of the limit pin and the circular groove 29, the sliding plate 25 slides back and forth, thereby driving the scraper 28 to slide back and forth synchronously, thereby achieving a certain degree of loosening and shaking of the slag and stone, ensuring the slag removal efficiency and avoiding the problem of slag and stone being difficult to separate and fall off.

[0038] In order to adjust the extended length of the shovel blade 28, and then use it in different geological layers, and without moving the entire equipment, to carry out slag removal processing on slag stones at different distances, the limit sleeve 24 is slidably connected to the sliding groove 23, and the limit groove is fixedly connected to an oil inlet pipe 33 on the side of the limit groove close to the scraper bucket 22, and the limit sleeve 24 is fixedly connected to a sliding piston 34 on the side of the limit sleeve 24 close to the scraper bucket 22, and the sliding piston 34 is connected to the inside of the sliding groove 23 through a spring, and the oil inlet pipe 33 is connected to an external pressure supply device, and the external pressure supply device is in a pressure supply process, which drives the sliding piston 34 to slide, and the sliding piston 34 slides, thereby driving the limit sleeve 24 and the sliding plate 25 to slide synchronously, thereby further adjusting the position of the shovel blade 28.

[0039] During the process of expanding and removing debris in the inclined well, the rock formations of different resisting layers are different, which will cause the adhesion of mud in the bucket 22, thereby affecting the removal efficiency of the bucket 22. At the same time, if it is not cleaned for a long time, it will cause the accumulation and adhesion of mud and debris, thereby increasing the weight of the bucket 22, making the bucket 22 very cumbersome to work. In order to achieve regular cleaning of the bucket 22 and ensure that the cleaning can be completed in the inclined well, automatic cleaning can be achieved, and the intensity of workers can be reduced, the interior of the bucket 22 is hollow to form a liquid injection cavity 35, and a plurality of limiting slots are opened inside the bucket 22. A lifting spray column 37 is slidably connected to the limiting slot up and down, and the upper end of the lifting spray column 37 is fixedly connected to a sealing cap 38 mounted on the lifting spray column 37, and the sealing cap 38 and the lifting spray column 37 are clearance-matched. The lifting and lowering liquid spray column 37 and the liquid injection chamber 35 are connected by a spring, and the liquid injection chamber 35 is connected to an external pressure supply device. The pressure supply device is used to pressurize the interior of the liquid injection chamber 35, and the pressure in the liquid injection chamber 35 increases, thereby driving the lifting and lowering liquid spray column 37 to slide upward. While the lifting and lowering liquid spray column 37 slides, it drives the sealing cap 38 to slide synchronously. When the sealing cap 38 and the limiting slot hole are disengaged, the cleaning liquid is sprayed to the interior of the scraper bucket 22 through the lifting and lowering liquid spray column 37, thereby cleaning the scraper bucket 22. At the same time, for the adhered debris, during the sliding process of the sealing cap 38, the debris inside the scraper bucket 22 is pre-treated, and then cleaned by spraying the cleaning liquid, thereby ensuring the effective cleaning of the interior of the scraper bucket 22.

[0040] The injection chamber 35 is communicated with a liquid storage bin 39 provided at one end of the scraper bucket 22 near the dipper rod 19, the liquid storage bin 39 is communicated with a telescopic tube 40 fixedly connected to the scraper bucket 22, the telescopic tube 40 is connected to an external liquid supply device, and liquid is supplied to the injection chamber 35 through the liquid storage bin 39 and the telescopic tube 40. At the same time, an electromagnetic valve is connected between the liquid storage bin 39 and the injection chamber 35, and the connection between the liquid storage bin 39 and the injection chamber 35 is controlled by the electromagnetic valve, thereby controlling the filling of the cleaning fluid.

[0041] In order to achieve control over the stability of the entire equipment, after the equipment is moved to a suitable position, it is necessary to assist in fixing the equipment to prevent the equipment from sliding or shaking on its own, thereby affecting the normal operation of the equipment. At the same time, due to the unevenness of the inner wall of the inclined shaft, the telescopic length of the leg 8 needs to be adapted to local conditions. Therefore, adaptive adjustment is also required during the telescopic process of the leg 8. Therefore, the leg 8 includes a leg sleeve 41 fixedly connected to the frame 5, and a telescopic leg 42 is slidably connected inside the leg sleeve 41. The telescopic leg 42 is fixedly connected to one end of the telescopic leg 42 near the frame 5 with a telescopic piston 43. The leg sleeve 41 is connected to an external pressure supply device, and the pressure supply process is carried out in the pressure supply device to achieve the telescopic leg 42.

[0042] The telescopic leg 42 is fixedly connected to a limit plate 44 at one end away from the leg sleeve 41, and a plurality of limit rivet rods 45 are connected to the limit plate 44. A pressure sensor is fixedly connected to the limit plate 44, and the effective limit of the entire equipment is achieved through the cooperation of the limit rivet rods 45 and the inner wall of the inclined shaft. At the same time, the pressure sensor on the limit plate 44 realizes the pressure supply control of the leg sleeve 41. The leg sleeve 41 is fixedly connected with a solenoid valve, and the solenoid valve is connected to the pressure sensor. When the limit plate 44 reaches a certain pressure, the solenoid valve is closed, so that the multiple legs 8 can be independently supported and limited, thereby ensuring the stability of the equipment.

[0043] Due to the unevenness of the wall surface, the extension and contraction degrees of the limiting rivet rod 45 on the same limiting plate 44 are different. In order to ensure the precise control of the limiting rivet rod 45, a limiting shaft hole 46 matching the limiting rivet rod 45 is provided on the limiting plate 44. The limiting rivet rod 45 and the limiting shaft hole 46 are connected by a spring. An adjusting bin 47 is provided inside the limiting plate 44. The adjusting bin 47 is connected to the limiting shaft hole 46. The limiting shaft hole 46 and the adjusting bin 47 are connected. A buffer structure is coaxially arranged inside the limiting shaft hole 46. The buffer structure includes two symmetrically distributed buffer circular plates 48. A buffer spring is connected between the two buffer circular plates 48. The buffering of the limiting rivet rod 45 is achieved through the cooperation of the buffer circular plates 48, the limiting shaft hole 46 and the adjusting bin 47 to avoid strong extrusion and deformation of the limiting rivet rod 45. The adjusting bin 47 and the limiting shaft hole 46 are filled with hydraulic oil.

[0044] When the present invention is used, the frame is moved to the working surface, and then the legs are unfolded to fix the entire equipment. The rock drilling arm system is moved to the lowermost end of the frame 5 by extending and retracting the slide system to perform drilling operations. After the drilling is completed, the slide is moved up to hide the rock drilling arm system inside the frame 5. The staff loads explosives on the face. After the explosives are loaded, the legs are retracted, and the frame is moved away from the working surface for blasting. After the blasting, the tunnel is ventilated. After the ventilation is completed, the frame system is driven to slide by the wire rope and the pulley block, thereby realizing the movement of the entire equipment to the working surface, and then the slag removal operation is performed through the slag removal system. When the axial feed of the boom seat 17 enters the slag accumulation area to push the slag into the slag chute, the arm seat 17 can rotate radially by + / -180°, and the slag pushing operation of the slag working arm can be realized within a 360-degree range of the circumference. The axial feed / retraction of the boom telescopic section 13 and the radial rotation action can realize the slag from the upper layer to the lower layer, from the far slag chute entrance to the near slag chute entrance into the slag chute, thereby realizing the slag removal operation in the inclined shaft. At the same time, the adjustment of the scraper bucket 22 is realized through the scraper bucket hydraulic cylinder 50, the scraper bucket connecting rod 49, the scraper bucket 22, the bucket arm 19 and other structures, so as to adapt to inclined shafts in different scenes and ranges, and at the same time ensure that the slag can better enter the interior of the scraper bucket 22.

[0045] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
