Problems solved by technology
However, since the construction workpieces in tunnel construction are generally large in size and heavy in weight, when the crane is subjected to a large external force or the track is inclined, the rollers of the crane are extremely easy to roll along the track and also collide with the track. sliding, or even slide due to idling of the rollers; in the case of large deformation of the track or the body of the crane, the rollers on the crane are extremely prone to derailment

Embodiment Construction
[0032] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only the technical solutions of the present invention. Some, but not all, embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.
[0033] see figure 1 with figure 2 , this embodiment provides a crane that can be applied in tunnel construction. The crane includes a beam 1 and a first crane 2 for connecting workpieces. The crossbeam 1 extends along the extending direction of the tunnel, on which a rack and a first guide rail are arranged. The first crane 2 has a gear 21 meshing...

The invention relates to the technical field of hoisting machinery, and discloses a crane. The crane comprises a cross beam and a first hoisting crane used for being connected with a workpiece, wherein the first hoisting crane is provided with gears which are meshed with a rack on the cross beam, and are driven by a power source so as to drive the first hoisting crane, rolling wheels which are arranged on a first guide rail of the cross beam in a rolling mode, and guide wheels which are arranged on the side face of the cross beam in a rolling mode. According to the first hoisting crane, the cross beam is used to bear the rack and the guide rail, so that the bearing capacity of the rack and the guide rail is increased; gears are arranged on the first hoisting crane for driving, thus it is guaranteed that the first hoisting crane is not prone to slipping when the crane runs; the rolling wheels with the supporting function are arranged on the first hoisting crane, so that the radial forceborne by the gears are reduced; and the guide wheels are arranged on the first hoisting crane, so that it is guaranteed that the first hoisting crane is not prone to derailing.
Description
technical field [0001] The invention relates to the technical field of hoisting machinery, in particular to a crane. Background technique [0002] During the construction of the tunnel, construction pieces such as segments on the four walls of the tunnel and box culverts on the bottom of the tunnel must be transported into the tunnel by the transport platform, and then lifted by the crane and sent to the predetermined installation position. [0003] In the prior art, the crane generally lifts the workpiece through the rails and the crane running along the rails. Wherein, the crane generally only moves the workpiece to the top of the target installation position through rollers along the track, and then lowers the workpiece to complete the installation. However, since the construction workpieces in tunnel construction are generally large in size and heavy in weight, when the crane is subjected to a large external force or the track is inclined, the rollers of the crane are e...
