[0025] In order to make the purpose, technical scheme and advantages of the utility model more clear, the following will make further detailed description of the features and performance of the tunnel crane transfer vehicle in the utility model in combination with the drawings and examples.

[0026] Example one

[0027] A tunnel crane transfer vehicle comprises a chassis 1, a walking mechanism 2 arranged at the lower part of the chassis 1 and a main frame 3 arranged on the chassis 1, and a hoisting device 4 is arranged on the main frame 3. The hoisting device 4 comprises a rotating shaft 41 arranged on the main frame 3 and perpendicular to the plane of the chassis 1, a rotating cross beam 42 in rotational cooperation with the rotating shaft 41 and an electric hoist 43 arranged on the rotating cross beam 42 and capable of moving along the length direction of the rotating cross beam 42. The rotating shaft 41 is arranged below the main frame 3 and on the center line of the length direction of the chassis 1, and the rotating cross beam 42 is capable of rotating in a plane perpendicular to the rotating shaft 41, so as to increase the hoisting range of the electric hoist 43. In the specific arrangement, the rotating cross beam 42 can be in rotational cooperation with the rotating shaft 41 at one end and freely rotate at the other end, or can be in rotational cooperation with the rotating shaft 41 at the middle part. As a preferred embodiment, the rotating cross beam 42 is in rotational cooperation with the rotating shaft 41 at one end and freely rotates at the other end, so as to reduce the lateral requirement for the operation space of the transfer vehicle. A driving motor for controlling the rotation of the rotating cross beam 42 around the rotating shaft 41 is arranged at the rotating cross beam 42.

[0028] A bearing platform for loading the objects to be transferred is arranged on the chassis 1. A sunken part 11 is arranged on the chassis 1 between the driving wheel 21 and the driven wheel 22, and the bearing platform is arranged above the sunken part 11. The sunken part 11 is used to lower the gravity center of the whole transfer vehicle, so as to make it more stable during the driving and hoisting.

[0029] The walking mechanism 2 comprises the driving wheel 21 and the driven wheel 22, and the driving wheel 21 and the driven wheel 22 are arranged at the two ends of the length direction of the chassis 1 respectively. The walking mechanism 2 further comprises a steering mechanism for controlling the steering of the driving wheel 21, so as to control the driving direction of the transfer vehicle. In the specific design, the driving wheel and the steering mechanism can be selected from common driving forms such as electric drive and hydraulic drive according to the actual situation. As a preferred embodiment, the driving wheel and the steering mechanism are both controlled by hydraulic pressure.

[0030] The main frame 3 is arranged on the chassis 1 through a lifting mechanism 5, and the height of the main frame 3 on the chassis 1 can be adjusted through the lifting mechanism 5. The lifting mechanism 5 comprises a vertical column 51 arranged vertically on the chassis 1, a vertical column outer sleeve 52 arranged on the main frame 3 and used to cooperate with the vertical column 51, and a hydraulic push rod 53 arranged between the chassis 1 and the main frame 3. The vertical column outer sleeve 52 can slide up and down along the vertical column 51, and adjusting the length of the hydraulic push rod 53 can make the main frame 3 slide along the length direction of the vertical column 51, so as to adjust the height of the main frame 3 on the chassis 1.

[0031] In particular, the number and layout of the upright columns 51 and hydraulic push rods 53 are set according to the actual size specifications of the transport vehicle. As a preferred embodiment, two upright columns 51 are provided at each corner of the chassis 1, and one upright column sleeve 52 is provided at each corner of the main frame 3. Each upright column sleeve 52 can cooperate with the two upright columns 51 at the corresponding position, and one hydraulic push rod 53 is provided at each upright column sleeve 52.

[0032] The transport vehicle is provided with a hydraulic station for driving the on-board hydraulic equipment. The driving wheel 21, steering mechanism, and hydraulic push rod 53 are all driven by the hydraulic station.

[0033] The transport vehicle is also provided with a power supply assembly for supplying power to the on-board electrical equipment. The power supply assembly can be connected to an external power source for power input, or it can be a battery or a diesel generator. The present application takes the battery as an example for illustration. The hydraulic station, electric hoist, on-board electrical system, and distance sensor for anti-collision warning provided on the transport vehicle are all powered by the power supply assembly.

[0034] The hydraulic station and power supply assembly are both located above the walking mechanism 2 on the chassis 1, without occupying the storage space of the sunken part 11.

[0035] In specific implementation, the object to be transported to the construction site in the tunnel is hoisted to the carrying platform outside the tunnel by the hoisting device 4. By rotating the rotating beam 42 and operating the electric hoist 43 to move on the rotating beam 42, the coverage of the electric hoist 43 can be increased, and the hoisting and placement of the object can be easily realized without frequent movement of the transport vehicle to move the electric hoist 43 to the appropriate hoisting point.

[0036] After loading is completed, the height of the main frame 3 is adjusted to enable the transport vehicle to adapt to the size of the tunnel. The transport vehicle is driven by the driving wheel 21 to move along the tunnel to the construction area, and the object on the carrying platform is unloaded by the hoisting device 4, completing the one-time loading and transportation process.

[0037] Embodiment Two

[0038] Different from Embodiment One, in Embodiment Two, the rotating shaft 41 is slidably arranged below the main frame 3 through the moving beam 44, which is perpendicular to the length direction of the chassis 1 and can slide on the main frame 3 along the length direction of the chassis 1, for further improving the coverage of the hoisting device 4.

[0039] Embodiment Three

[0040] Different from Embodiment One, in Embodiment Three, a steering mechanism is also provided at the driven wheel 22, for reducing the turning radius of the transport vehicle and improving its flexibility in the space-limited tunnel.

[0041] It should be noted that the parts not described in detail in the scheme are all prior art, and the above examples are only used to illustrate the utility model, but the utility model is not limited to the above examples, and any simple modification, equivalent change and modification of the above examples according to the technical essence of the utility model all fall within the protection scope of the utility model.
