Description

Technical Field

[0001] The present invention relates to the technical field of tool transportation, and particularly relates to a tool transportation system for an inclined shaft tunneling machine. Background Art

[0002] In recent years, with the development of pumped-storage power stations, there are more and more large-slope inclined shaft tunnels, which has accelerated the development of inclined shaft tunneling machines. Tool transportation is a necessary link in the overhaul process of the cutterhead of a tunneling machine. The traditional tool transportation system generally includes a tool-carrying beam (such as I-beam, H-beam) and a lifting hoist that moves on the tool-carrying beam. This tool transportation system is suitable for the horizontal transportation of tools in a flat tunnel, but cannot meet the inclined transportation of tools in an inclined shaft.

[0003] Chinese invention patent with the authorization announcement number CN112412478B discloses a tunnel inclined shaft construction system, including a tunneling mainframe. The tunneling machine includes a cutterhead, a main drive, and a cross-shaped beam (i.e., the mainframe beam) arranged in sequence. The cutterhead and the main drive enclose a tool bin, and the main drive has a drive box communicating with the cross-shaped beam. A tool transportation tooling is arranged in the cross-shaped beam. The tool transportation tooling includes a guide rail arranged on the top of the cross-shaped beam. An electric hoist is connected to the guide rail through a walking braking mechanism, and a hook is arranged on the electric hoist; a rack is arranged on the guide rail, and the walking braking mechanism includes a gear meshing with the rack and a motor for driving the gear to rotate. The electric hoist moves along the guide rail with the walking braking mechanism under the drive of the motor to transport the tool from the cross-shaped beam into the drive box, and then from the drive box into the tool bin, realizing the lifting and transportation of the tool.

[0004] In the above patent, the walking braking mechanism moves along the guide rail through the meshing of the gear and the rack. However, during climbing, the impact force is relatively large during the transmission process of the gear and the rack, resulting in easy wear of the gear and the rack, affecting the walking of the walking braking mechanism on the guide rail, and further affecting the lifting and transportation of the tool. Summary of the Invention

[0005] The purpose of the present invention is to provide a tool transportation system for an inclined shaft tunneling machine to solve the problem that the wear is easy to occur during the transmission process of the gear and the rack during climbing in the prior art, which affects the lifting and transportation of the tool.

[0006] To achieve the above purpose, the technical solution of the tool transportation system for the inclined shaft tunneling machine of the present invention is as follows:

[0007] The tool transportation system of an inclined shaft tunneling machine includes a cutter head, a main drive, and a main machine beam arranged in sequence. A tool bin is formed between the cutter head and the main drive. The main drive has a drive box communicating with the main machine beam. A first tool feeding hole is provided at the bottom of the main machine beam. A first hoisting device is provided in the main machine beam for hoisting tools at the bottom of the tunnel into the main machine beam through the first tool feeding hole. A supporting track for supporting tools is provided at the bottom of the main machine beam and extends from the first tool feeding hole into the drive box. A winding device is provided in the main machine beam or the drive box. The hoisting cable of the winding device is used to connect with the tools on the supporting track to pull the tools on the supporting track from the main machine beam into the drive box. A second tool feeding hole is provided on the box wall of the drive box close to the tool bin. A second hoisting device is provided in the tool bin for hoisting the tools in the drive box into the tool bin through the second tool feeding hole.

[0008] The beneficial effects are as follows: In the present invention, the first hoisting device is used to hoist the tools into the main machine beam, then the winding device pulls the tools on the supporting track from the main machine beam into the drive box, and then the second hoisting device hoists the tools in the drive box into the tool bin. This process is not only convenient to operate, but also labor-saving, safe, and reliable, solving the problem that it is difficult to transport tools from the bottom of the tunnel to the tool bin under large slope working conditions. In addition, during the tool hoisting process, gear-rack meshing transmission is not used, avoiding the problem that the gears and racks affect the walking of the walking braking mechanism on the guide rail due to wear.

[0009] As a further improvement, the winding device is arranged in the main machine beam, and a first fixed pulley is provided at a position close to the top in the drive box. The hoisting cable of the winding device bypasses the first fixed pulley.

[0010] The beneficial effects are as follows: Since the space in the drive box is relatively narrow, arranging the winding device in the main machine beam is beneficial to the installation of the winding device.

[0011] As a further improvement, the winding device is arranged at the bottom of the main machine beam, and a second fixed pulley is provided at the top in the main machine beam. The hoisting cable of the winding device bypasses the second fixed pulley and the first fixed pulley in sequence.

[0012] The beneficial effects are as follows: Arranging the winding device at the bottom of the main machine beam is beneficial to the maintenance and repair by operating personnel.

[0013] As a further improvement, a tool temporary storage platform is provided beside the first tool feeding hole in the main machine beam.

[0014] The beneficial effects are as follows: During the process of the winding device pulling the tools in the main machine beam into the drive box, the first hoisting device can hoist the tools at the bottom of the tunnel into the main machine beam and place them on the tool temporary storage platform to improve the tool changing efficiency.

[0015] As a further improvement, a protection cable is provided at the top in the main machine beam for connecting with the tools on the supporting track.

[0016] The beneficial effects are as follows: When the tool slides on the supporting track, the protective cable can protect the tool, preventing the tool from injuring people or damaging equipment due to accidental falling.

[0017] As a further improvement, a protective door for opening or closing the second tool feeding hole is provided on the inner side of the box wall of the drive box close to the tool magazine.

[0018] The beneficial effects are as follows: The protective door can prevent the slag and stones in the tool magazine from falling into the drive box and the main beam of the host, ensuring the safety of personnel and equipment.

[0019] As a further improvement, a tool magazine operation platform is detachably connected to the outer side of the box wall of the drive box close to the tool magazine, and a drive box operation platform is provided inside the drive box.

[0020] The beneficial effects are as follows: By providing the tool magazine operation platform and the drive box operation platform, it is convenient for the operators to stand and temporarily place the tools.

[0021] As a further improvement, the supporting track includes a base, and a cylindrical slide rail extending along the length direction of the main beam of the host is provided on the base. Two cylindrical slide rails are arranged at intervals along the width direction of the main beam of the host.

[0022] The beneficial effects are as follows: With such a design, the cylindrical slide rail is in line contact with the tool, which can reduce the friction between the tool and the supporting track.

[0023] As a further improvement, both the first lifting device and the second lifting device are manual hoists, electric hoists or pneumatic hoists.

[0024] The beneficial effects are as follows: Manual hoists, electric hoists or pneumatic hoists are all existing mature products, which are not only easy to obtain, but also relatively labor-saving to operate.

[0025] As a further improvement, the winding device is a hydraulic winch.

[0026] The beneficial effects are as follows: The hydraulic winch can utilize the hydraulic system carried on the rear support of the roadheader, and only need to lay hydraulic pipelines, making the layout of the hydraulic winch relatively simple. BRIEF DESCRIPTION OF THE DRAWINGS

The tool magazine operation platform 27 is detachably connected to the outer side of the box wall of the drive box 12 by inserting the plug rod into the sleeve. Among them, a ladder 28 is also provided on the outer side of the box wall of the drive box 12 to facilitate the operator to move from the second feed hole 38 to the tool magazine operation platform 27.

[0049] In this embodiment, a drive box operation platform 26 for the operator to stand on is provided inside the drive box 12. The drive box operation platform 26 is beside the upper end of the supporting track 24 and is used for temporarily placing the tool 23.

[0050] As Figure 2 shown in the figure, the supporting track 24 includes two parallel I-beams 32. Connecting rib plates 31 are provided between the two I-beams 32. A steel plate 34 and a steel pipe 33 are welded to the top of each I-beam 32. The steel pipe 33 is inside the steel plate 34, and the steel pipe 33 extends along the length direction of the main beam 13. Among them, the steel pipe 33 forms a cylindrical slide rail. The two steel pipes 33 are arranged at intervals along the width direction of the main beam 13. The steel pipe 33 can guide the tool 23 and reduce the frictional resistance. The two I-beams 32, the two connecting rib plates 31 and the two steel plates 34 together form a base.

[0051] In this embodiment, a handrail 35 is provided on the side wall inside the main beam 13 to facilitate the operator to enter the drive box 12 from inside the main beam 13.

[0052] In this embodiment, both the first lifting device 19 and the second lifting device 30 are chain hoists. In other embodiments, the first lifting device and the second lifting device can be electric hoists or pneumatic hoists.
