Description

Technical Field

[0001] The invention relates to a remote-controlled electric prying trolley, belonging to the technical field of mine tunnel repair. Background Art

[0002] During the mining process (tunnel, coal mine tunnel excavation and metal mine mining, etc.), loose stones often appear on the top and side walls of the mine after blasting. If these stones are not cleaned up in time, they will be in danger of falling off at any time. The falling stones can easily injure the workers, thus bringing many hidden dangers to production operations. The method often used is: workers stand on the built rack and use steel chisels to pry it down. This not only has high labor intensity and low work efficiency, but also when large areas of stones fall off, if the workers do not have time to avoid it, it will also bring safety hazards to the construction workers. At this time, the prying trolley came into being, realizing the mechanization of prying work. The Chinese invention patent with patent number CN202211251926.9 discloses a small-scale prying trolley working arm, which is provided with a telescopic inner cylinder protective cover outside the telescopic inner cylinder to protect the pitch cylinder and telescopic cylinder on the equipment, thereby improving the equipment's safety protection capability and reliability; the Chinese utility model patent with patent number CN202122621334.9 discloses a remote equipment loading trolley, which can be flexibly moved to a position suitable for remote control of the loaded equipment in complex working environments such as most construction sites.

[0003] However, the inventors of the present invention discovered that the prior art has the following problems: existing scraping trolleys are mostly powered by diesel engines, which may cause explosions when encountering combustible gases such as gas. Operators are required to actually go down the well to operate the equipment, further increasing the safety risks for personnel. In addition, the exhaust gas discharged by the scraping trolleys accumulates in the tunnel space for a long time, causing discomfort to the operators. Therefore, improvements are needed.

DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0020] The first embodiment of the present invention relates to Figure 1 A remote-controlled electric prying trolley is shown, comprising a frame 1, a chassis device 2, a power device 3, a cockpit 4 and an execution device 5. The chassis device 2 is symmetrically installed on both sides below the frame 1; the power device 3 is arranged on the right side above the frame 1; the cockpit 4 is arranged on the left side above the frame 1; and the execution device 5 is arranged on the left end of the frame 1.

[0021] The second embodiment of the present invention is basically the same as the first embodiment, mainly in that the scheme of the execution device is optimized. The execution device 5 includes a support turntable 51 and a first hydraulic cylinder 52; the support turntable 51 is rotatably connected to the frame 1; the fixed end of the first hydraulic cylinder 52 is fixed to the frame 1, and the telescopic end is fixed to the bottom of the support turntable 51. The support turntable 51 can make the breaker 510 in the execution device 5 rotate relative to the frame 1 along the Z axis in the Cartesian coordinate system; the first hydraulic cylinder 52 provides power for its rotation.

[0022] The actuator 5 also includes a second hydraulic cylinder 53, a boom 54 and a telescopic arm 55; the upper end of the support turntable 51 is fixedly connected to the boom 54; the inner cavity of the boom 54 is slidably connected with the telescopic arm 55; the fixed end of the second hydraulic cylinder 53 is fixed to the support turntable 51, and the telescopic end is fixed to the boom 54. The boom 54 is similar to a "human arm" and can add a dynamic freedom degree to the actuator 5; the second hydraulic cylinder 53 can provide power for the movement of the boom 54; the telescopic arm 55 can increase the length of the actuator 5 when in use, and can trim the top of the lane; when not in use, it can be retracted and folded to keep the structure of the prying trolley compact so that it can travel freely in the lane.

[0023] The actuator 5 further includes a third hydraulic cylinder 56 and a small arm 57; one end of the small arm 57 is rotatably connected to the end of the telescopic arm 55; the fixed end of the third hydraulic cylinder 56 is fixed to the telescopic arm 55, and the telescopic end is fixed to the small arm 57. The small arm 57 can also provide the actuator 5 with another degree of freedom in the same direction as the large arm 54, and the third hydraulic cylinder 56 provides power for its movement.

[0024] The actuator 5 also includes a first swing joint 58, a second swing joint 59 and a breaker 510; the first swing joint 58 and the second swing joint 59 are rotatably connected between the end of the arm 57 and the bottom of the breaker 510. The breaker 510 is the end-actuating tool, which can remove unstable rocks that are prone to fall and collapse after the tunnel blasting operation; the first swing joint 58 and the second swing joint 59 increase the freedom of action of the actuator 5, and the two degrees of freedom are perpendicular to each other, which can ensure that the tunnel can be operated in all directions.

[0025] The actuator 5 also includes a connecting rod 511, a push plate 512 and a fourth hydraulic cylinder 513; the connecting rod 511 is fixedly connected to the same side of both ends of the push plate 512; the other end of the connecting rod 511 is rotatably connected to the frame 1; the fixed end of the fourth hydraulic cylinder 513 is fixedly connected to the frame 1, and the telescopic end is fixedly connected to the middle of the push plate 512. The push plate 512 is used to clean up the scattered rocks that fall on the ground of the tunnel; the connecting rod 511 is used to connect the frame 1 and the push plate 512 to always ensure the horizontal orientation of the push plate 512; the fourth hydraulic cylinder 513 provides power for the lifting and lowering of the push plate 512.

[0026] The third embodiment of the present invention is basically the same as the first embodiment, mainly in further optimization. The power device 3 includes an electro-hydraulic proportional control system 31 and a battery module 32; the electro-hydraulic proportional control system 31 is installed above the frame 1; the upper part of the electro-hydraulic proportional control system 31 is fixedly connected to the battery module 32. The battery module 32 provides forward power for the entire prying trolley and is the power of the high-pressure hydraulic oil of the electro-hydraulic proportional control system 31; the electro-hydraulic proportional control system 31 provides control and power functions for each sub-hydraulic system in the actuator 5.

[0027] The chassis device 2 includes a chassis 21, rotating wheels 22 and tracks 23; the chassis 21 is fixedly connected to the bottom of the frame 1; the rotating wheels 22 are rotatably connected at both ends of the chassis 21; the tracks 23 cover the two rotating wheels 22 and are rotatably connected thereto. The chassis 21 is an important load-bearing device of the prying trolley. Like the chassis of a car, the better the performance of the chassis 21, the better the seismic resistance of the prying trolley; the rotating wheels 22 are driven to rotate by the battery module 32, thereby driving the tracks 23 to rotate synchronously; the tracks 23 have a large contact area with the roadway ground, which can reduce pressure and adapt to a variety of complex terrains.

[0028] The cockpit 4 includes an operating platform 41, an operating lever 42 and an indicator light 43; the operating platform 41 is fixed above the frame 1; the operating lever 42 is connected in an array on the operating platform 41; and an indicator light 43 is provided on one side of the operating lever 42. The operating platform 41 displays the current operating data of the prying trolley; the operating lever 42 is used to manually operate the prying trolley under special circumstances; and the indicator light 43 can use light and voice to display the current state of the prying trolley.

[0029] A fire extinguisher 44 is provided between the operating platform 41 and the electro-hydraulic proportional control system 31, which meets the industry technical standards and can handle accidental fire situations in a timely manner.

[0030] Based on the above, a typical working process of the present invention is: like Figure 1 As shown, when the present invention is implemented, the walking control and rock hammering control of the prying trolley in the underground tunnel can be carried out in the control room on the ground through digital image transmission technology. The battery pack module 32 drives the rotating wheel 22 to rotate, driving the crawler 23 to rotate synchronously, so that the prying trolley moves forward or backward. The battery pack module 32 pressurizes the hydraulic oil, and controls the extension and retraction of the first hydraulic cylinder 52 through the electro-hydraulic proportional control system 31, so that the actuator 5 rotates around the frame 1; controls the extension and retraction of the second hydraulic cylinder 53 to lift the boom 54 upward; at the same time, the telescopic arm 55 is controlled to extend and retract relative to the boom 54 as needed, so that the mechanical arm is extended or retracted; controls the extension and retraction of the third hydraulic cylinder 56 to lift the small arm 57 upward; the increased degrees of freedom of the first swing joint 58 and the second swing joint 59 allow the breaker 510 to freely hammer the rock at any angle and direction.
