[0002] Rail-mounted cranes are widely used in tunnel construction to lift tunnel segments, construction equipment components (heavy and irregularly shaped parts), etc. A rail-mounted crane mainly consists of rails, hydraulic cylinders, a traveling trolley, an electric chain hoist, and wheels. Rail-mounted cranes used in construction equipment typically require precise material lifting and have a wide lifting range.

[0003] The existing belt conveyor technology has the following main drawbacks: 1. Track cranes are usually monorail beam type, which can only move along the tunnel axis. Lateral adjustment requires manual assistance, resulting in low precision and low efficiency.

[0004] 2. The components being hoisted by the construction equipment are quite heavy, and the risk of track deformation must be avoided. Therefore, there are high requirements for the structure of the rail crane.

[0005] 3. The components of the construction equipment require a large amount of space, and there are high requirements for the lifting range.

[0006] Therefore, it is necessary to provide a new type of rail crane and construction equipment to solve the above-mentioned technical problems. Utility Model Content

[0029] See Figures 1 to 3 This embodiment provides a novel rail-mounted crane including a crossbeam 1, a longitudinal moving mechanism 2, and a lifting mechanism 3. The crossbeam 1 is slidably mounted on the longitudinal moving mechanism 2. The longitudinal moving mechanism 2 is mounted on a trailer frame 4 and can drive the crossbeam 1 to move vertically. The lifting mechanism 3 is slidably mounted on the crossbeam 1 and can slide along the crossbeam 1. The lifting mechanism 3 is used for lifting materials. In actual operation, the novel rail-mounted crane uses the longitudinal moving mechanism 2 to drive the crossbeam 1 to move vertically, roughly positioning the material above the target area. Then, the lifting mechanism 3 moves along the crossbeam 1 to make lateral fine adjustments to the material's position, achieving precise positioning of the material in a two-dimensional plane, eliminating blind spots in the operation. The combination of the longitudinal moving mechanism 2 and the lifting mechanism 3 increases the lifting range, and the structure is simple, significantly improving lifting efficiency and accuracy.

[0030] The longitudinal moving mechanism 2 includes a longitudinal rail 2.1 vertically mounted on the trailer frame 4 and a longitudinal drive component 2.2. The crossbeam 1 is slidably mounted on the longitudinal rail 2.1, and the output end of the longitudinal drive component 2.2 is connected to the crossbeam 1. The longitudinal drive component 2.2 can extend and retract to move the crossbeam 1 up and down along the longitudinal rail 2.1, thereby enabling rough positioning of materials in the height direction. In this embodiment, the longitudinal drive component 2.2 is a hydraulic cylinder. A cylinder seat 1.4 is provided on the crossbeam 1. The mounting end of the longitudinal drive component 2.2 is hinged to the trailer column, and the output end of the longitudinal drive component 2.2 is hinged to the cylinder seat 1.4 to accommodate vibrations during operation and avoid concentrated stress.

[0031] Specifically, the longitudinal moving mechanism 2 further includes a connecting seat 2.3 and a connecting plate 2.4. The connecting seat 2.3 is detachably mounted on the trailer frame 4, and the longitudinal drive component 2.2 is hinged between the connecting seat 2.3 and the crossbeam 1. The longitudinal track 2.1 is detachably connected to the trailer frame 4 through multiple spaced connecting plates 2.4. The longitudinal drive component 2.2 and the longitudinal track 2.1 are detachably connected to the trailer frame 4 through the connecting seat 2.3 and the connecting plate 2.4, respectively, so as to flexibly adjust the setting position of the longitudinal moving mechanism 2 on the trailer frame 4 to adapt to various operational needs. The longitudinal track 2.1 is connected to the trailer frame 4 through multiple spaced connecting plates 2.4, thereby achieving multi-point bolting fixation and effectively avoiding stress concentration.

[0032] Furthermore, the longitudinal moving mechanism 2 also includes a limiting member 2.5, which is disposed on the trailer frame 4 and sleeved around the outer periphery of the longitudinal driving member 2.2. The limiting member 2.5 can limit the longitudinal driving member 2.2 and also improve the connection strength between the longitudinal driving member 2.2 and the trailer frame 4, which is beneficial to improving operational stability and safety.

[0033] Furthermore, the number of longitudinal moving mechanisms 2 is one or more, and the longitudinal moving mechanisms 2 are symmetrically arranged about the crossbeam 1. The number of longitudinal moving mechanisms 2 can be one or more, and the cooperation of each longitudinal moving mechanism 2 helps to improve the stability of the crossbeam 1 during vertical movement. In this embodiment, there are two longitudinal moving mechanisms 2, which are symmetrically arranged at both ends of the crossbeam 1.

[0034] In this embodiment, the crossbeam 1 includes a main beam 1.1 and a set of traveling wheels 1.2. The main beam 1.1 is slidably connected to the longitudinal track 2.1 via the set of traveling wheels 1.2, and one set of traveling wheels 1.2 is provided for each longitudinal track 2.1. The longitudinal track 2.1 has grooves extending along its length on both sides. The set of traveling wheels 1.2 includes a mounting base and two pairs of rollers oppositely mounted on the mounting base. The longitudinal track 2.1 is positioned between the two pairs of rollers, and the two pairs of rollers are slidably positioned within their respective grooves to achieve a sliding connection between the crossbeam 1 and the longitudinal track 2.1.

[0035] In this embodiment, the main beam 1.1 is provided with a plurality of connecting hole groups spaced apart along the length direction, and the traveling wheel group 1.2 can be detachably connected to any of the connecting hole groups by fasteners. The mounting base of the traveling wheel group 1.2 can be detachably connected to any connecting block by fasteners to facilitate adjustment of the installation position of the traveling wheel group 1.2 on the main beam 1.1. In this embodiment, there are two longitudinal moving mechanisms 2, and each of the two longitudinal moving mechanisms 2 is respectively provided with one traveling wheel group 1.2. This embodiment can adapt to different spacing of longitudinal moving mechanism 2 settings by changing the spacing between the two traveling wheel groups 1.2, improving flexibility and expanding the scope of application.

[0036] Furthermore, the crossbeam 1 also includes a connecting rod 1.3, and each set of traveling wheels 1.2 arranged along the length of the main beam 1.1 is detachably connected via the connecting rod 1.3. The fact that each set of traveling wheels 1.2 along the length of the main beam 1.1 is connected to a connecting rod 1.3 helps maintain the synchronization of the traveling wheels 1.2 along the length direction, resulting in a more stable and reliable structure, stronger vibration resistance, and improved smoothness of movement of the crossbeam 1. Moreover, by equipping connecting rods 1.3 of different steel profiles, the traveling wheels 1.2 can be slidably connected to the longitudinal track 2.1 under different sized trailer frames 4 conditions.

[0037] In this embodiment, the hoisting mechanism 3 includes a traveling trolley 3.1 and an electric hoist 3.2. The traveling trolley 3.1 is slidably mounted on the crossbeam 1 and can move along the crossbeam 1. The electric hoist 3.2 is mounted on the traveling trolley 3.1 and is used to hoist materials. The crossbeam 1 is equipped with a gear rail. The traveling trolley 3.1 travels on the gear rail of the crossbeam 1 via a motor-driven gear to make lateral fine adjustments to the material position. The electric hoist 3.2 is suspended below the traveling trolley 3.1 to complete the final precise hoisting operation.

[0038] The novel rail crane in this embodiment has the following significant advantages: Precise lifting with full coverage: By combining the longitudinal movement driven by hydraulic cylinders and the lateral movement of electric trolleys, the crane achieves precise positioning in a two-dimensional plane, eliminating blind spots, providing a large lifting range, and significantly improving lifting efficiency and accuracy.

[0039] Modular design, reusable: The two longitudinal tracks 2.1, independently connected to the frame, perfectly adapt to different sized construction equipment trailer frames 4. The disassembled tracks and the entire machine can be reused, greatly saving costs.

[0040] Quick installation and stable structure: The multi-point bolted track installation method avoids stress concentration and thermal deformation problems caused by welding, resulting in faster installation, more stable and reliable structure, and stronger vibration resistance.

[0041] High practicality: Simple structure, easy to operate, especially suitable for the harsh construction environment of shield tunnels, and has high promotion value.

In this embodiment, the main body is a tunnel boring machine (TBM).
