Abstract
The utility model discloses a combined bridge crane in adaptation district rate radius tunnel, including the girder with install the landing leg in girder bottom, the girder is equipped with vertical pinhole and installs vertical round pin axle including head and the tail looks articulated multisection crossbeam in proper order, the coupling point between two sections adjacent crossbeams, the one end of two section adjacent crossbeams is equipped with horizontal pinhole respectively and installs the transverse bolt axle in coupling point's both sides, is in the same place two section adjacent crossbeam fixed connection. The utility model discloses can erect one section roof beam, prepare under the condition in tunnel the adjustment of bending of a bridge crane's girder, comply with the curvature radius in tunnel, when having solved frame bridge crane and crossing the tunnel transition, need the difficult problem of large -scale hoisting equipment and dismouting girder, simultaneously the utility model discloses practice thrift the reerection time, also reduced the cost of dismouting on a large scale and workman's intensity of labour, and made simple, low cost, strong adaptability, safe and reliable.
Description
Technical field
The utility model relates to Bridge Erector field, specifically a kind of bridging machine for both highway and railway adapting to rate radius tunnel, community.
Background technology
Along with the construction of highway in China, railway construction bridge is more and more general, the continuous change of Construction unit construction plant, environment and equipment requirement for Multiple tunnel requirement when adaptation highway, railway are set a roof beam in place: (1), because the size of beam block is different, the girder length of Bridge Erector is different; (2) tunnel face sectional dimension change; (3) length in tunnel and the change of curvature reducing.Above three kinds of situations, when public affairs, railway bridge erecting machine via hole, need to use Large-scale Hoisting equipment, carry out dismounting on a large scale; Labour intensity is large, and cost is high, length consuming time.
For meeting needs of setting a roof beam in place, Bridge Erector needs to carry out operation by tunnel, and when crossing tunnel, because tunnel face diameter is little, radius of curvature is little, and crane ' s major girder itself is oversize, long, when by tunnel, interferes, directly can not pass through tunnel with tunnel wall.
Utility model content
The purpose of this utility model is to provide a kind of bridging machine for both highway and railway adapting to rate radius tunnel, community, Bridge Erector is when crossing small curve tunnel, crane ' s major girder can carry out horizontal bending, to solve Bridge Erector when crossing tunnel, because girder is oversize, long, be not easy to the problem re-assemblying tunnel.
The technical solution of the utility model is as follows:
A kind of bridging machine for both highway and railway adapting to rate radius tunnel, community, include girder and be arranged on the supporting leg bottom girder, it is characterized in that: described girder includes the more piece crossbeam that head and the tail are hinged successively, hinge point between adjacent two joint crossbeams is provided with vertical pin-and-hole and is provided with vertical bearing pin, one end of adjacent two joint crossbeams is respectively equipped with horizontal pin-and-hole in the both sides of hinge point and is provided with horizontal bearing pin, is fixed together by adjacent two joint crossbeams.
The bridging machine for both highway and railway in described rate radius tunnel, adaptation community, is characterized in that: described supporting leg includes the interim supporting leg in front portion, front leg strut, middle supporting leg and the tail supporting leg that are arranged on successively from front to back bottom described girder.
The bridging machine for both highway and railway in described rate radius tunnel, adaptation community, is characterized in that: the top of described girder is provided with hoisting overhead travelling crane.
When building a bridge, horizontal bearing pin and vertical bearing pin are all in installment state, and now transverse bolt bearing is by load when setting a roof beam in place; When crossing tunnel, take out horizontal bearing pin, vertical pinned connection, adjacent two joint crossbeams can be rotated a certain angle by vertical bearing pin, make whole girder form and tunnel radius of curvature form similar, can tunnel excessively safely.
The beneficial effects of the utility model:
The utility model can set up one section of beam, carried out bending adjustment, and complied with the radius of curvature in tunnel when preparing tunnel to the girder of Bridge Erector, solves Bridge Erector when crossing tunnel transition, needs a difficult problem for large lifting equipment and dismounting girder; Simultaneously the utility model has been saved and has been re-assemblied the time, also reduces the cost of dismounting on a large scale and the labour intensity of workman, and manufactures simple, with low cost, strong adaptability, safe and reliable.

Fig. 2 is the structural representation of the utility model middle girder.
Fig. 3 is the syndeton schematic diagram of adjacent two joint crossbeams in the utility model.
Detailed description of the invention
See accompanying drawing, a kind of bridging machine for both highway and railway adapting to rate radius tunnel, community, the supporting leg including girder 1 and be arranged on bottom girder 1, girder 1 includes the more piece crossbeam that head and the tail are hinged successively, hinge point between adjacent two joint crossbeams is provided with vertical pin-and-hole and is provided with vertical bearing pin 2, one end of adjacent two joint crossbeams is respectively equipped with horizontal pin-and-hole in the both sides of hinge point and is provided with horizontal bearing pin 3, is fixed together by adjacent two joint crossbeams.
In the utility model, supporting leg includes the interim supporting leg in front portion 4, front leg strut 5, middle supporting leg 6 and the tail supporting leg 7 that are arranged on successively from front to back bottom girder 1.
The top of girder 1 is provided with hoisting overhead travelling crane 8.
Below in conjunction with accompanying drawing, the utility model is further described:
When building a bridge, horizontal bearing pin 3 and vertical bearing pin 2 are all in installment state, and now horizontal bearing pin 3 bears load when setting a roof beam in place; When crossing tunnel, horizontal bearing pin 3 takes out, and vertical bearing pin 2 connects, and adjacent two joint crossbeams can be rotated a certain angle by vertical bearing pin 2, and namely girder 1 can carry out horizontal bending, makes girder 1 form and tunnel radius of curvature form similar, can tunnel excessively safely.
In sum, the utility model, when not needing large-scale lifting appliance to assist, can adjust the carrying out of large-span girder, adjusts the form between tunnel, safety tunnel, is a kind of novel device of safe and reliable, easy and simple to handle, low cost.
