Description

Technical Field

[0001] The utility model relates to a hoisting device, in particular to a hoisting device for a horizontal axis tunneling machine. Background Art

[0002] In modern engineering construction, tunnel boring machines are widely used in tunnels, mines, underground pipelines and other projects, and are important engineering machinery and equipment. With the complexity and expansion of engineering projects, the hoisting and movement of tunnel boring machines have become an indispensable part of the construction process. Traditional tunnel boring machine hoisting equipment usually has the following problems:

[0003] Traditional lifting equipment is usually simple in design, with limited freedom of rotation and movement, and is difficult to adapt to complex construction environments. Especially in narrow or irregular working spaces, lifting operations are greatly restricted and the lifting angle and direction cannot be flexibly adjusted.

[0004] Many hoisting equipment are prone to shaking or tilting under heavy load conditions, especially when the telescopic arm is in a long working state, the stability is even more difficult to ensure. This not only affects the hoisting efficiency, but also poses a major safety hazard.

[0005] The operating systems of some lifting equipment are relatively complex and require multiple manual adjustments and calibrations, which increases the difficulty and time cost of operation. This not only reduces construction efficiency, but also makes it easy for human operating errors to occur, affecting construction progress and quality.

[0006] Traditional lifting equipment has a complex structure, many components, and a cumbersome maintenance process. Especially in harsh construction environments, the equipment failure rate is high, which increases maintenance costs and downtime.

[0007] In order to improve the hoisting efficiency and operational flexibility of the tunnel boring machine, the present invention proposes an efficient and stable hoisting device for a horizontal axis tunnel boring machine, aiming to overcome the shortcomings of the prior art and provide a hoisting solution with a reasonable structure, easy operation, safety and reliability. Utility Model Content

[0008] In order to solve the above problems, the following technical solutions are proposed:

[0009] A lifting device for a horizontal axis tunneling machine includes a base and a lifting mechanism. A mounting groove is provided on the top of the base, a rotating platform is arranged in the mounting groove, the rotating platform is rotatably connected to the base, a telescopic arm is installed on the base, the telescopic end of the telescopic arm is installed with the lifting mechanism, a first oil cylinder is installed on the telescopic arm, the telescopic end of the first oil cylinder is fixedly connected to the telescopic end of the telescopic arm through a connecting block, and a second oil cylinder is also included, the two ends of the second oil cylinder are respectively hinged to the rotating platform and the lower end of the telescopic arm through hinges.

[0010] Furthermore, the rotating platform is rotatably connected to the bottom of the mounting groove via a first rotating shaft, a first gear is arranged on the first rotating shaft, and also includes a rotating motor installed on the top of the base, the rotating motor is transmission-connected to a second rotating shaft, the second rotating shaft passes through the top of the base and is rotatably connected to the bottom of the mounting groove, a second gear is installed on the second rotating shaft, and the second gear is connected to the first gear via a chain transmission.

[0011] Furthermore, a supporting roller is installed at the bottom of the installation groove, and the supporting roller abuts against the bottom of the rotating platform.

[0012] Furthermore, the lifting device includes a winding roller and a lifting rope, one end of the lifting rope is installed on the winding roller, and the other end of the lifting rope is installed with a hook.

[0013] Furthermore, the winding roller is driven by a motor.

[0014] Furthermore, the lifting device also includes two positioning wheels arranged opposite to each other, and the lifting rope passes between the two positioning wheels.

[0015] Furthermore, the telescopic arm is hinged on the mounting seat away from the telescopic end, and the mounting seat is fixedly connected to the rotating platform.

[0016] The beneficial effects of the utility model are as follows:

[0017] The hoisting device for a horizontal axis tunneling machine of the present invention has significant beneficial effects. First, by providing a rotating platform and a telescopic arm, multi-directional adjustment of the hoisting mechanism is achieved. The rotating platform can rotate freely on the base, and through the first rotating shaft and the first gear transmission system, the rotating platform can achieve precise angle adjustment, thereby improving the flexibility and efficiency of the hoisting operation. This is particularly important for operations in narrow spaces or complex terrains, and can effectively avoid obstacles and improve work efficiency.

[0018] Secondly, the design of the telescopic arm greatly increases the operating range of the lifting device. The telescopic arm can be adjusted in length by the drive of the first oil cylinder to meet the lifting requirements of different heights and distances. At the same time, the setting of the second oil cylinder further enhances the stability and adjustment ability of the telescopic arm. Through the hinge connection, it can provide strong support and adjustment force between the rotating platform and the telescopic arm, ensuring stability and safety during the lifting process.

[0019] In addition, the design of the hoisting mechanism is also very practical. Through the cooperation of the winding roller and the lifting rope, objects can be hoisted and placed conveniently and quickly. The motor-driven winding roller can realize the automatic retraction and release of the lifting rope, which greatly facilitates the operation. The setting of the two positioning wheels makes the movement trajectory of the lifting rope more stable and accurate, preventing the lifting rope from deviating during the work process, and ensuring the smooth progress of the lifting process.

[0020] In summary, the hoisting device for a horizontal axis tunnel boring machine provided by the present invention not only has a reasonable structural design and is easy to operate, but also greatly improves the efficiency and safety of the hoisting work, and has broad application prospects and market value.

[0028] The working principle of the utility model is as follows:

[0029] Rotation of the rotating platform 2: The rotating platform 2 is rotatably connected to the bottom of the mounting groove 11 through the first rotating shaft 21, and the first gear 22 is installed on the first rotating shaft 21. The rotating motor 3 drives the second gear 32 through the second rotating shaft 31, and the second gear 32 is connected to the first gear 22 through a chain. When the rotating motor 3 is started, it drives the second rotating shaft 31 and the second gear 32 to rotate, and then drives the first gear 22 and the first rotating shaft 21 through the chain, so that the rotating platform 2 can realize rotation on the base 1.
