Description

Technical Field

[0001] This utility model relates to the field of shield tunneling machine steel pipe installation technology, and in particular to a shield tunneling machine steel pipe installation lifting device. Background Technology

[0002] As the core equipment for tunnel construction, tunnel boring machines (TBMs) are widely used in tunnel projects such as subways, railways, and highways. During the construction process of TBMs, steel pipe installation is a critical and frequent operation that requires the use of specialized lifting devices.

[0003] When hoisting steel pipes, these devices mainly rely on simple mechanical arms or ropes to lift the pipes from the ground to the designated installation position. However, in actual operation, due to the lack of an effective stabilizing structure for the swaying during the hoisting process, the stability of the steel pipe lifting is poor. For example, in some narrow tunnel spaces, the lifting device is easily affected by the surrounding environment, such as airflow interference from the tunnel walls and vibration transmission caused by uneven ground, resulting in significant swaying of the lifted steel pipe. Moreover, when the steel pipe itself is heavy or has special specifications, existing lifting devices are even more difficult to maintain its stable state. This unstable lifting process greatly increases the construction danger. On the one hand, the swaying steel pipe may collide with surrounding construction equipment or tunnel walls, causing equipment damage and tunnel structure destruction; on the other hand, on-site construction personnel may face the risk of being injured by the swaying steel pipe at any time, seriously threatening their lives and affecting the progress and quality of the entire project. Utility Model Content

[0004] In order to overcome the problem that existing shield machine steel pipe installation and lifting devices lack a stable structure to prevent swaying during the steel pipe hoisting process, resulting in poor lifting stability and high construction risk, this utility model provides a shield machine steel pipe installation and lifting device.

[0005] The technical solution is as follows: The shield tunneling machine steel pipe installation and lifting device includes a steel pipe clamping assembly and a slewing boom type lifting assembly; the upper end of the steel pipe clamping assembly is equipped with the slewing boom type lifting assembly; the steel pipe clamping assembly includes a cross hanger, a lifting ring, a hydraulic cylinder, a roller slide, a lifting rod, and a steel pipe shovel; the slewing boom type lifting assembly includes a slewing boom lifting column and an electric chain hoist.

[0006] Furthermore, a lifting ring is provided at the upper center of the cross-shaped hanger, and the lifting ring is fixedly connected to the cross-shaped hanger.

[0007] Furthermore, hydraulic cylinders are installed around the lifting ring, and the hydraulic cylinders are located above the cross-shaped lifting frame. There are four hydraulic cylinders, and the hydraulic cylinders are remotely controlled by an external remote control.

[0008] Furthermore, each hydraulic cylinder is equipped with a roller carriage at its output end, and the rollers of the roller carriage are slidably connected along the slide rail on the upper end face of the cross hanger.

[0009] Furthermore, a hanger is provided at the lower end of the roller carriage, and the hanger is fixedly connected to the roller carriage.

[0010] Furthermore, a steel pipe shovel is installed on the inner side of the lower end of the boom, and the steel pipe shovel is fixedly connected to the boom.

[0011] Furthermore, an electric chain hoist is installed above the lifting ring, and the output end of the electric chain hoist is connected to the lifting ring for hoisting.

[0012] Furthermore, the upper end of the electric chain hoist is equipped with a slewing arm lifting column, and the slewing arm lifting column is hoisted and connected to the electric chain hoist.

[0013] The beneficial effects are as follows: After receiving instructions from the control system, the internal piston of this utility model reciprocates through the hydraulic cylinder, converting hydraulic energy into mechanical energy. The extension and retraction of the hydraulic cylinder generates driving force, which acts on the roller slide, driving the rollers on the roller slide to slide along the track groove on the upper end face of the cross-shaped lifting frame. The track groove is processed with high precision, with a smooth surface and accurate dimensions, ensuring smooth sliding of the rollers. When lifting steel pipes, the four roller slides are driven by the hydraulic cylinder to adjust their positions according to the size and shape of the steel pipe. The roller slides drive the connected lifting rods and steel pipe shovels to move synchronously until the four lifting rods and steel pipe shovels clamp the steel pipe. During the clamping process, the steel pipe is limited by the lifting rods on all sides and the lower end is grabbed by the steel pipe shovel, forming a stable mechanical support structure. When the lifting encounters external interference or shaking, the steel pipe is constrained in multiple directions, and its position and posture remain stable. Compared with the traditional lifting method, this device reduces the risk of steel pipe tilting and slipping during lifting, improves the safety and reliability of lifting operations, and ensures the smooth progress of engineering construction.

[0014] By setting up a slewing boom type lifting assembly, the steel pipe clamping assembly is lifted and raised using an electric chain hoist to realize the lifting function of the shield machine steel pipe. In conjunction with the slewing boom movement adjustment of the slewing boom lifting column, the lifting and horizontal movement adjustment functions of the steel pipe are realized.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] like Figures 1-6 As shown, the shield tunneling machine steel pipe installation and lifting device includes a steel pipe clamping assembly 1 and a slewing boom type lifting assembly 2; the slewing boom type lifting assembly 2 is installed at the upper end of the steel pipe clamping assembly 1; the steel pipe clamping assembly 1 includes a cross hanger 101, a lifting ring 102, a hydraulic cylinder 103, a roller slide 104, a lifting rod 105, and a steel pipe shovel 106; the slewing boom type lifting assembly 2 includes a slewing boom lifting column 201 and an electric chain hoist 202.

[0025] A lifting ring 102 is provided at the upper center of the cross-shaped hanger 101, and the lifting ring 102 is fixedly connected to the cross-shaped hanger 101.

[0026] Hydraulic cylinders 103 are provided around the lifting ring 102, and the hydraulic cylinders 103 are located above the cross-shaped lifting frame 101. There are four hydraulic cylinders 103, and the hydraulic cylinders 103 are remotely controlled by an external remote controller.

[0027] Each hydraulic cylinder 103 is equipped with a roller slide 104 at its output end, and the rollers of the roller slide 104 are slidably connected along the slide groove track on the upper end face of the cross hanger 101.

[0028] A hanger 105 is provided at the lower end of the roller carriage 104, and the hanger 105 is fixedly connected to the roller carriage 104.

[0029] A steel pipe shovel 106 is provided on the inner side of the lower end of the boom 105, and the steel pipe shovel 106 is fixedly connected to the boom 105.

[0030] After receiving commands from the control system, the internal piston of the hydraulic cylinder 103 reciprocates, converting hydraulic energy into mechanical energy. The extension and retraction of the hydraulic cylinder 103 generates driving force, which acts on the roller slide 104, driving the rollers on the roller slide 104 to slide along the track groove on the upper end face of the cross-shaped lifting frame 101. The track groove is precision-machined, with a smooth surface and accurate dimensions, ensuring smooth roller sliding. When lifting steel pipes, the four roller slides 104, driven by the hydraulic cylinders 103, adjust their positions according to the size and shape of the steel pipe. The connected booms 105 and steel pipe shovel 106 move synchronously until the four booms 105 and steel pipe shovel 106 clamp the steel pipe. During the clamping process, the steel pipe is limited by the booms 105 on all sides and the lower end is gripped by the steel pipe shovel 106, forming a stable mechanical support structure. When the hoisting encounters external interference or shaking, the steel pipe is constrained in multiple directions, and its position and posture remain stable. Compared with traditional hoisting methods, this device reduces the risk of the steel pipe tilting or slipping during hoisting, improves the safety and reliability of hoisting operations, and ensures the smooth progress of engineering construction.

[0033] By setting up the slewing boom type lifting assembly 2, the steel pipe clamping assembly 1 is lifted and raised by the electric chain hoist 202 to realize the lifting function of the shield machine steel pipe. In conjunction with the slewing boom lifting column 201, the lifting and horizontal movement adjustment functions of the steel pipe are realized.
