[0039] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts shall fall within the scope of protection of the present invention.

[0040] Please refer to Figure 1 and Figure 2 . The utility model provides an inclined shaft excavation trolley. The inclined shaft excavation trolley includes a trolley body 10 that is rollingly mounted on a track in the inclined shaft, and a support shoe mechanism 30, a slag scraper arm 50, a rock drilling arm 70 and a spray protection device 90 mounted on the trolley body 10. The trolley body 10 includes an upper installation area 101 and a lower installation area 103 arranged one above the other. One end of the rock drilling arm is fixedly mounted on the lower installation area 103, and the other end can be extended toward the tunnel face and the rock wall for drilling. One end of the slag scraper arm 50 is fixedly mounted on the bottom of the upper installation area 101, and the other end can be extended toward the tunnel face for scraping. The spray protection device 90 is mounted on the upper installation area 101, and the other end is fixed on the slag scraper arm or the rock drilling arm for mixing the material under the drive of the slag scraper arm and the rock drilling arm and then spraying the slurry toward the well wall. Therefore, by integrating the rock drilling arm 70, the slag removal arm 50 and the spray protection device 90 into the trolley body 10, multiple arms work together to realize operations such as drilling holes in the well wall of the excavation trolley, removing slag to the guide well, and spraying grouting on the well wall, so as to complete the entire process of inclined well excavation, reduce the labor intensity and operation risks of inclined well construction, and greatly improve the operation efficiency. Moreover, the spray protection device, the rock drilling arm and the slag removal arm are respectively fixed on different installation areas of the trolley body, and will not cause interference during each operation, which effectively reduces the occurrence of operation failure rate.

[0041] It should be noted that the trolley body 10 moves along the track under the traction of the traction system, which includes a control room, a winch, a wire rope and a guide wheel. The winch operates under the control of the control room and pulls the wire rope to pull the trolley body to move. Figure 2 and Figure 3As shown, one side of the gripper mechanism 30 is fixed to the trolley body 10, while the other side is retracted toward the wellbore wall to support the rock wall. The gripper mechanism 30 is mounted on the trolley body 10 and is used to support the wall of the inclined well. The gripper mechanism 30 comprises at least one gripper unit 31, which includes multiple gripper frames 33 and multiple movable grippers 35. The gripper frames 33 are connected at one end and extend in multiple directions with their other ends centered at the intersection of the gripper frames 33. Each movable gripper 35 is telescopically mounted within its corresponding gripper frame 33. Therefore, a shoe support frame 33 is set in different directions, and the movable shoe 35 set in the shoe support frame 33 can be extended or shortened. The change in its length can not only meet the requirements of retraction and support of the shoe system, but also the movable shoe 35 can perform telescopic movement in multiple directions, so that it can be tightened to the inclined well wall from multiple directions. In this way, it can be attached to the well wall from multiple directions, which greatly improves the supporting force of the shoe mechanism 30, thereby ensuring the stability of the trolley 10 in the underground position.

[0042] Preferably, the plurality of shoe grippers 33 are two side shoe grippers 37 in opposite directions and a front shoe gripper 39 arranged perpendicular to the side shoe grippers 37. In this embodiment, there are three shoe grippers 33, which support the well wall from three directions, namely, left and right directions and upward directions, forming multiple fulcrums to tightly adhere the movable shoe 35 to the well wall.

[0043] As a preferred implementation manner of this embodiment, a support rod 40 is further fixedly connected between the side support shoe frame 37 and the front support shoe frame 39. The support rod 40 is arranged near the intersection of the side support shoe frame 37 and the front support shoe frame 39 to strengthen the structural stability between the side support shoe frame 37 and the front support shoe frame 39.

[0044] Specifically, in this embodiment, there are two gripper units 31, which are connected by a connecting frame 41 and arranged in parallel. The two gripper units 31 can also be connected together to form a whole (module), and multiple gripper units can be provided according to different needs to improve its applicability.

[0045] See also Figure 4 and Figure 5Specifically, the movable gripper 35 includes a movable gripper 351, a telescopic rod 353, a connector 357, and a gripper seat 359. The movable gripper 351 is axially sleeved within the gripper frame 33, and the telescopic rod 353 is axially sleeved within the movable gripper 351. One end of the telescopic rod 353 is fixedly connected to the gripper frame 33 via a positioning column 360, and the other end is fixedly connected to the connector 357. The outer periphery of the connector 357 is connected to the movable gripper 351, and the end of the connector 357 is connected to the gripper seat 359 by a ball joint. The telescopic rod 353 performs telescopic motion, driving the connector 357 to move, and the connector 357 in turn drives the movable gripper 351 connected thereto to move. In this way, the movable gripper 351 achieves the purpose of reciprocating and telescopic motion within the gripper frame 33. It is worth noting that the connecting head 357 is connected to the support shoe seat 359 by a ball joint, so that the connection between the connecting head 357 and the support shoe seat 359 can form a variety of angles, so that the support shoe seat 359 can automatically adapt to the angle of the well wall, and the support shoe seat 359 is always in close contact with the well wall, which greatly improves the supporting force.

[0046] Specifically, in this embodiment, the telescopic rod 353 is a hydraulic cylinder. The piston rod of the hydraulic cylinder is connected to the connecting head 357, and the piston rod drives the connecting head 357 and the movable support shoe 351 connected to the connecting head 357 to move back and forth.

[0047] Specifically, in this embodiment, the positioning column 360 is a pin that passes through the shoe support frame 33 and the cylinder barrel of the hydraulic cylinder to fix the cylinder barrel, so that the piston rod can move back and forth in the cylinder barrel.

[0048] More preferably, in order to increase the friction between the shoe seat 359 and the well wall, the end of the shoe seat 359 away from the connecting head 357 is provided with a concave-convex anti-slip surface 3591.

[0049] In detail, the cross section of the shoe support frame 33 is square. Preferably, the shoe support frame 33 is made of square steel, which has a reliable structure.

[0050] In another embodiment, the gripper mechanism 30 further includes a flange 36, and the gripper frame 33 is externally fixedly connected with a plurality of flanges 36. The gripper mechanism 30 is connected to the trolley 10 frame via the flange 36, and the flange 36 is detachable, making assembly and disassembly more convenient.

[0051] like Figure 6As shown, the slag scraper arm 50 includes a large telescopic arm assembly 51, a small telescopic arm assembly 53, a rotating platform 57 and a bucket 59. The large telescopic arm assembly 51 is fixedly connected to the upper installation area 101 through a support. The rotating platform 57 includes a platform seat 571, a platform seat amplitude adjustment cylinder 573, a slewing mechanism 575 and a turntable seat 577. The two ends of the platform seat amplitude adjustment cylinder 573 are respectively connected to the large telescopic arm assembly 51 and the platform seat 571. The slewing mechanism 575 is installed as a whole with the platform seat 571. The turntable seat 577 is fixedly installed at the bottom of the slewing mechanism 575. One end of the small telescopic arm assembly 53 is rotatably connected to the turntable seat 577, and the other end is connected to the bucket 59. The rotation of the rotating platform 57 can drive the small telescopic arm assembly 53 to rotate 360 ​​degrees around the connection. Specifically, the slewing mechanism rotates 360°, driving the small telescopic arm assembly connected thereto to rotate 360°, thereby realizing 360° free slag removal by the slag scraping arm. At the same time, the platform seat variable amplitude cylinder 573 is actuated to control the pitch angle of the small telescopic arm assembly 53, thereby expanding the operating range of the bucket 59. During operation, slag scraping operations can be carried out over a large range without moving the slag scraping arm, which greatly improves work efficiency.

[0052] Specifically, in this embodiment, the telescopic boom assembly 51 includes a telescopic boom 511, a telescopic boom cylinder 513, and an adapter frame 515. One end of the telescopic boom cylinder 513 is hinged to one end of the telescopic boom 511 via an intermediate piece 517, and the other end is hinged to the other end of the telescopic boom 511. The adapter frame 515 is mounted on the end of the telescopic boom 511, and the platform base 571 is hinged to the other end of the adapter frame 515. The two ends of the platform base boom cylinder 573 are hinged to the adapter frame 515 and the platform base 571, respectively. The telescopic boom cylinder 513 controls the pitch angle of the telescopic boom, thereby controlling the pitch angle of the boom. The adapter frame 515 primarily serves as a connector to enhance structural stability.

[0053] Specifically, the large telescopic arm 511 includes a plurality of retractable large arms, each of which has a different inner diameter. The plurality of retractable large arms are sequentially arranged in one body to achieve length changes, thereby flexibly changing the length of the large telescopic arm. This retractable structure is an existing conventional technology and will not be described in detail in this embodiment.

[0054] Specifically, in this embodiment, the small telescopic arm assembly 53 includes a small telescopic arm 531 and a small telescopic boom cylinder 533. The two ends of the small telescopic arm are respectively hinged to the turntable seat 577 and the bucket 59. One end of the small telescopic arm boom cylinder 533 is hinged to the turntable seat 577, and the other end is hinged to the small telescopic arm 531.

[0055] Specifically, the small telescopic arm 531 includes a multi-section telescopic small arm frame, and the inner diameters of the multi-section small arm frame are different. The multi-section telescopic small arm frame is integrated into one body to achieve length changes, thereby flexibly changing the length of the small telescopic arm. This telescopic structure is an existing known technology and will not be repeated in this embodiment.

[0056] Specifically, the slewing mechanism 575 includes a slewing bearing and a slewing drive connected to the slewing bearing for driving the slewing bearing to rotate. The slewing drive drives the slewing bearing to move, and in turn drives the platform seat 571 mounted on the slewing bearing to rotate, thereby achieving different angles of rotation of the scraper arm.

[0057] Furthermore, the rotary drive includes a connected reducer and a motor, which can achieve speed control.

[0058] The small telescopic arm 531 is further fixedly connected to a mounting support 535 , and the small telescopic amplitude adjustment cylinder 533 is hinged to the small telescopic arm 531 via the mounting support 535 to improve the stability of the structural installation.

[0059] like Figure 7 、 Figure 8 and Figure 9 The figure shows the scraper arm in the retracted and operating state in the inclined shaft. The scraper arm, with its multi-angle rotation and pitching movements, can quickly scrape the slag into the pilot shaft. The scraper arm can be mounted on the lower part of the inclined shaft construction trolley to scrape the blasted slag into the pilot shaft chute. This meets the construction scope of the inclined shaft with a diameter of 6 to 9 meters, an inclination angle of 50 to 60 degrees, and a single footage of 2 to 3 meters. The posture of the scraper arm when not in operation does not affect the operation of other booms. In the retracted posture, the scraper arm can be retracted to facilitate the raising of the construction trolley to a safe position (30 meters from the tunnel face) during blasting. In addition, the scraper arm has good operability and high operating efficiency.

[0060] It is worth mentioning that, if Figure 8 As shown, the scraper arm can also be equipped with a manned platform 501, and workers can stand on the platform to perform operations such as anchoring and grouting.

[0061] like Figure 10 and 11 As shown, the rock drilling arm 70 is used to drill blastholes and anchor holes. The blastholes are parallel to the axis of the inclined shaft, and the anchor holes are perpendicular to the shaft wall. The rock drilling arm 70 includes a swing base 71, a boom assembly 73, a rotating arm assembly 75, and a rock drilling propulsion device 77. The bottom of the boom assembly 73 is pivotally connected to the swing base 71, and the end is pivotally connected to the rotating arm assembly 75. The boom assembly 73 controls the pitch of the rotating arm assembly 75 to different angles. The rotating arm assembly 75 rotates at different angles, driving the rock drilling propulsion device 77 to rotate at different angles to drill holes in the tunnel face and shaft wall within the inclined shaft.

[0062] like Figure 11 As shown, the swing seat 71 is installed and fixed on the lower installation area 103, and the trolley moves back and forth along the track installed in the inclined shaft. The entire drilling arm 70 can be moved to different positions for operation under the drive of the moving trolley. Figure 2 As shown, the swing seat 71 includes a swing base 711 and a swing cylinder 713 integrally mounted on the swing base 711. The bottom of the boom assembly 73 is hinged to the swing base 711. The swing cylinder 713 controls the left and right movement of the swing base 711, allowing the boom assembly 73 to change its drilling position as it moves left and right. This provides a flexible structure and a wider range of operation.

[0063] like Figure 13 As shown, specifically, one end of the swing cylinder 713 is hinged to the swing base 711 through a connecting bracket 712 to achieve the pitching movement of the swing base 711.

[0064] Specifically, the boom assembly 73 includes a boom 731, a boom pitch cylinder 733, and a support base 735. One end of the boom pitch cylinder 733 is hinged to the swing base 71, and the other end is hinged to the boom 731. The boom 731 and the rotating platform base 751 are rotatably connected via the support base 735. The boom pitch cylinder 733 controls the amplitude of the boom 731, thereby achieving the pitching movement of the entire boom. The boom assembly 73, combined with the rotating arm assembly 75, can achieve pitching and rotation angles, thereby simultaneously realizing the functions of drilling blasting holes and anchor holes. Among them, the boom 731 is composed of multiple sections of telescopic booms to achieve length changes. The inner diameters of the multiple sections of the booms are different, and the multiple sections of the telescopic booms are integrated to achieve length changes, thereby flexibly changing the length of the boom. This telescopic structure is a conventional technology and will not be described in detail in this embodiment.

[0065] Furthermore, the bottom of the boom 731 is also fixedly connected to a mounting support 737, and the boom pitch cylinder 733 and the swing seat 71 are both hinged on the mounting support 737. Installation through the mounting support 737 can improve the stability of the structure and make the structure more reasonable.

[0066] Specifically, the rotating arm assembly 75 includes a rotating platform seat 751, a slewing mechanism 753, a rotating arm 755, a platform seat pitch cylinder 757, a rotating arm swing cylinder 758 and a rotating arm pitch cylinder 759. The rotating platform seat 751 is hinged to the boom assembly 73, and the slewing mechanism 753 is assembled at the bottom of the rotating platform seat 751. One end of the rotating arm 755 is hinged to the bracket at the bottom of the slewing mechanism 753, and the other end is connected to the rotating arm swing cylinder 758. One end of the platform seat pitch cylinder 757 is hinged to the support seat 735 of the boom assembly, and the other end is hinged to the rotating platform seat 751. The rock drilling propulsion device 77 is connected to the rotating arm swing cylinder 758. One end of the rotating arm pitch cylinder 759 is hinged to the bottom of the rotating platform seat 751, and the other end is hinged to the rotating arm 755. The rotating arm 755 is extended and retracted to control the operational range of the rock drilling propulsion device 77. The rotating arm pitch cylinder 759 is extended and retracted to control the pitch angle of the rotating arm 755. Simultaneously, the platform base pitch cylinder 757 is extended and retracted to adjust the pitch angle of the rotating platform base 751, thereby controlling the pitch angle and rotation angle of the rock drilling propulsion device 77. The slewing mechanism 753 is controlled to rotate 360°. The slewing mechanism 753 drives the rotating arm 755 and the rotating arm pitch cylinder 759 to rotate, thereby driving the rock drilling propulsion device connected to the rotating arm 755 to rotate 360°. The rock drilling propulsion device 77 has an operational range with the boom assembly 73 and the rotating arm assembly 75 as the radius. This greatly increases the operating range of the rock drilling propulsion device 77 in the inclined shaft, allowing for wide-range operations without moving the entire drilling arm, effectively improving work efficiency.

[0067] The rotating arm 755 is comprised of multiple, retractable arms that can be adjusted in length. These arms have varying inner diameters, and the multiple retractable arms are telescopically integrated to allow for flexible length adjustment. This retractable structure is well known in the art and will not be further described in this embodiment.

[0068] Specifically, in this embodiment, the slewing mechanism 753 is a turntable. The turntable is an operating platform that performs controlled slewing motion, and the slewing arm assembly 75 rotates 360° driven by the turntable. Furthermore, the slewing mechanism 753 is composed of a slewing bearing and a slewing drive, wherein the slewing drive comprises a reducer and a motor.

[0069] like Figure 11As shown, specifically, the rock drilling propulsion device 77 includes a connecting seat 771, a propulsion pitch cylinder 773, a propulsion swing cylinder 775 and a rock drilling mechanism 777. The propulsion swing cylinder 775 is connected to the rotating arm assembly 75. One end of the connecting seat 771 is fixedly connected to the propulsion swing cylinder 775, and the other end is hinged to the rock drilling mechanism 777. One end of the propulsion pitch cylinder 773 is hinged to the connecting seat 771, and the other end is hinged to the rock drilling mechanism 777.

[0070] Specifically, in this embodiment, the connecting base 771 is L-shaped. A portion of the L-shaped connecting base 771 is mounted with the large arm 731 and the rotating platform base 751, and the other portion is bent and extended outward to be connected to other positionable components.

[0071] like Figure 13 Specifically, when the trolley is traveling or performing other operations, the boom assembly 73 and the rotary arm assembly 75 are fully retracted, and the drilling arm is retracted by operating the pitch cylinders and the swing cylinders without affecting other boom operations or trolley travel.

[0072] like Figure 14 The figure shows a drilling arm in a blasthole drilling position. By adjusting the swing cylinder 713, boom pitch cylinder 733, and the length of boom 731, while also adjusting the angle of the platform pitch cylinder 757 and the movement of the slewing mechanism 753, adjusting the length of the rotating arm pitch cylinder 759 and rotating arm 755, rotating the swing cylinder 713, advancing the swing cylinder, and moving the propulsion device pitch cylinder, the rock drilling propulsion device 77 is aligned parallel to the shaft axis. The rock drilling propulsion device 77 is then operated to drill the drill rod into the blasthole. After completing one blasthole, the various cylinders or the swing cylinder 713 are operated to move the drill rod to another blasthole location for drilling.

[0073] like Figure 15 As shown in FIG, the figure shows another posture of the rock drilling arm drilling a blasthole; after the rotary mechanism 753 rotates the angle, the adjustment method of the rock drilling arm is the same as the above-mentioned method of drilling a blasthole.

[0074] like Figure 16 and Figure 17 The figure shows two different positions of the rock drilling arm during anchor drilling. By adjusting the arm's position so that the slewing drive is positioned perpendicular to the shaft axis, the hydraulic cylinders and the swing cylinder are operated to align the rock drilling propulsion device 77 perpendicularly with the rock wall. The rock drilling propulsion device 77 is then operated to drill the drill rod into the hole. After completing one anchor hole, the next anchor hole can be drilled simply by rotating the slewing mechanism 753.

[0075] Furthermore, the actions and functions of each cylinder are as follows: by operating the swing cylinder 713, the entire boom assembly can be swung left and right, and by operating the boom pitch cylinder 733, the entire boom can be pitched. The platform seat pitch cylinder 757 can adjust the angle of the rotating platform seat 751, and the rotating arm pitch cylinder 759 can adjust the posture of the rotating arm assembly 75. The rotating arm swing cylinder can make its front end part rotate within a range of 360°, and the thrust swing cylinder can make its front end part swing within a range of 360° as a whole. The thrust pitch cylinder 773 can make the entire rock drilling propulsion device 77 pitch as a whole. The entire rock drilling arm structure is flexible and has a wide range of operability.

[0076] It should be explained that, in the present embodiment, a slag scraper arm and a rock drilling arm are integrated on the trolley. Of course, in other embodiments, there may be two slag scraper arms and one rock drilling arm (the slag scraper arm is integrated with a jetting device, or a rock drilling arm, a slag scraper arm and a shotcreting arm, or a rock drilling arm and a slag scraper arm (with an integrated jetting device on the slag scraper arm), or even a rock drilling arm (with an integrated jetting device on the rock drilling arm) and a slag scraper arm. Therefore, the number of slag scraper arms and rock drilling arms can be specifically configured according to the requirements of the inclined shaft diameter and footage.

[0077] like Figures 18-20 As shown, the spray protection device 90 includes a material stirring device 91, a material conveying chute 93, a pumping device 95 and an injection device 97. The material stirring device 91 and the pumping device 95 are respectively installed on the trolley 10 and are driven by the trolley to move in the inclined shaft. The material stirring device 91 and the pumping device 95 are connected through the material conveying chute 93 to transport the material into the pumping device 95. The pumping device 95 is connected with the injection device 97 through a pipeline for spraying the material. Specifically, concrete and water are mixed in the material mixing device 91 and stirred, and then discharged to the pumping device 95 through the feeding chute 93. The pumping device 95 pumps the concrete to the injection device 97. Therefore, the inclined well spray protection device first mixes the concrete and water in the material mixing device 91 and then conveys them to the pumping device 95 through the feeding chute 93 to pump out the material. In this way, the entire mixing and pumping operation can be carried out on the inclined well construction trolley, and the feeding chute 93 can ensure the transportation of dry mixed materials without problems such as pipe blockage or aggregate separation, thereby ensuring smooth construction, greatly improving work efficiency, and reducing construction costs.

[0078] in,

[0079] Specifically, the upper installation area 101 includes an upper platform 105 and a lower platform 107 spaced apart from each other. The material stirring device 91 is arranged on the upper platform 105 of the trolley body, and the pumping device 95 is arranged on the lower platform 107 of the trolley. By providing different platforms on the trolley body to install the material stirring device 91, the device can be installed on the trolley for operation in an inclined shaft.

[0080] Furthermore, a notch is provided on the tabletop of the lower platform 107, and the material delivery chute 93 passes through the notch to the inlet of the pumping device 95. It can be understood that the notch is provided to avoid the material delivery channel and improve the rationality of the structure.

[0081] See also Figure 20 Specifically, in this embodiment, the material mixing device 91 includes a mixing hopper 911, a mixing shaft 913, and a mixing drive 915. The mixing drive 915 is installed at the bottom of the mixing hopper 911 to drive the mixing shaft 913 to move. The mixing shaft 913 is installed in the mixing hopper 911, and the discharge port of the mixing hopper 911 is connected to the feed chute 93. The mixing shaft 913 turns in the mixing hopper to fully mix the concrete and water to form a mixed slurry. Preferably, the mixing drive is a motor.

[0082] Furthermore, a plurality of bolt blades 914 are mounted on the stirring shaft 913, and the bolt blades 914 are evenly spaced along the axis of the stirring shaft 913. The bolt blades 914 can increase the stirring force of the stirring shaft 913, thereby making the material more evenly mixed.

[0083] Specifically, in this embodiment, the pumping device 95 includes a loading hopper 951, a material buffer plate 953 installed in the loading hopper 951, and a driver 957 installed below the loading hopper 951. The outlet of the feed chute 93 is located within the opening of the loading hopper 951. The loading hopper 951 receives the mixed material from the material mixing device 91, and the driver 957 pumps the material to the injection device 97. Preferably, the driver 957 is a mixing pump commonly used on concrete mixers.

[0084] Specifically, the feeding chute 93 is T-shaped, that is, the diameter of one end of the feeding chute 93 connected to the material stirring device 91 is larger than that of the other end, so that the material can be fed into the loading hopper 951 at a uniform speed.

[0085] Specifically, the spraying device 97 is a nozzle. Preferably, the nozzle is a nozzle on an existing concrete spraying machine.

[0086] The spraying device 97 is mounted on a shotcrete arm, and with the aid of the shotcrete arm, the spraying device sprays the concrete slurry onto the wall of the inclined shaft. It is understood that the shotcrete arm can be a rock drilling arm or a slag scraping arm, and the booms of the rock drilling arm and the slag scraping arm can be extended and tilted to different angles to assist the spraying device in spraying the concrete slurry onto the wall of the inclined shaft.

[0087] The inclined shaft excavation trolley provided by the embodiment of the present invention integrates the rock drilling arm 70, the slag removal arm 50 and the spray protection device 90 into the trolley body 10, and multiple arms work together to realize operations such as drilling holes in the well wall of the excavation trolley, removing slag to the guide well, and spraying grouting on the well wall, so as to complete the entire process of inclined shaft excavation, reduce the labor intensity and operation risks of inclined shaft construction, and greatly improve the operation efficiency. Moreover, the spray protection device, the rock drilling arm and the slag removal arm are respectively fixed on different installation areas of the trolley body, and the various arms will not cause interference when operating, which effectively reduces the occurrence of operation failure rate.

[0088] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
