Abstract
The utility model relates to a kind of single girder portal crane, comprise girder, be arranged on the supporting leg of both sides below girder, be arranged on the bottom linker below supporting leg, be fixedly mounted on the roller box below bottom linker, be arranged on the dolly above girder, the suspender be connected with dolly and operator's compartment, described girder adopts the I-beam section of inverted triangle structure to be formed by connecting, be connected by the first bearing pin between bottom linker with roller box, changing two girder is in the past that the I-beam section of inverted triangle structure is formed by connecting, the mode changing in the past traditional case wheel fixing with bottom linker is be connected by the first bearing pin between bottom linker with roller box, connection mode complex structure in the past, waste raw MAT'L, present girder connection mode is under the prerequisite of safety, save raw MAT'L, some movable joints can be made, transport and easy to assembly, and solve the problem of curved in tracks.
Description
Technical field
The utility model relates to civil construction, is specifically related to a kind of hoisting crane, particularly one list girder portal crane.
Background technology
Transfer crane is the one distortion of crane in bridge type.At harbour, be mainly used in the loading and unloading operation of outdoor goods yard, stock ground goods, bulk goods.Its metal construction is as door-shaped frame, and install two legs under support main beam, can directly walk on the track on ground, girder two ends can have overhanging cantilever beam.Transfer crane has the features such as utilization of area rate is high, scope of work large, it is wide to adapt to, highly versatile, is used widely in goods yard, harbour.
Traditional cucurbit main beam of gantry crane is equilateral triangle, and its form structure is complicated, waste raw MAT'L, and the material realizing large span is cumbersome when transporting, and cannot break joint, without movable joint; The leg structure of traditional transfer crane connects complicated, can not flexible assembling, and transport is inconvenient, installs inconvenient, can not realize splitting transport; Support and the base connection of traditional transfer crane adopt bolt with flange to be connected, it is fixing for focusing on method of attachment, wheel operationally, when running into track turn or lay bending, just there will be the phenomenon of rotation browsing rail, cause hoisting crane can not the operation of normal table.As from the foregoing, traditional transfer crane complex structure, install and dismounting dumb, transport inconvenience, be subject to the restriction of unreasonable structure during operation, cause serious waste of resources, inefficiency.
Therefore, produce a kind of structure simply, easy to operate, in-site installation is convenient, flexible, and stability is strong, and save raw MAT'L, convenient transportation, single girder portal crane that work efficiency is high, has market outlook widely.
Summary of the invention
For the deficiencies in the prior art, the utility model provides that a kind of structure is simple, easy to operate, in-site installation is convenient, flexible, stability is strong, saves raw MAT'L, convenient transportation, single girder portal crane that work efficiency is high.
The technical solution of the utility model is achieved in that a kind of single girder portal crane, comprise girder, be arranged on the supporting leg of both sides below girder, be arranged on bottom linker below supporting leg, be fixedly mounted on roller box below bottom linker, be arranged on the dolly above girder, the suspender be connected with dolly and operator's compartment, described girder adopts the I-beam section of inverted triangle structure to be formed by connecting, and is connected between bottom linker with roller box by the first bearing pin.
Described supporting leg is isosceles trapezoid, and supporting leg is provided with reinforcement connecting rod, strengthens connecting rod and is connected with supporting leg by the second bearing pin.
The utility model has following good effect: the utility model structure is simple, comprise girder, be arranged on the supporting leg of both sides below girder, be arranged on the bottom linker below supporting leg, be fixedly mounted on the roller box below bottom linker, be arranged on the dolly above girder, the suspender be connected with dolly and operator's compartment, described girder adopts the I-beam section of inverted triangle structure to be formed by connecting, be connected by the first bearing pin between bottom linker with roller box, changing two girder is in the past that the I-beam section of inverted triangle structure is formed by connecting, the mode changing in the past traditional case wheel fixing with bottom linker is be connected by the first bearing pin between bottom linker with roller box, connection mode complex structure in the past, waste raw MAT'L, present girder connection mode is under the prerequisite of safety, save raw MAT'L, some movable joints can be made, transport and easy to assembly, and solve the problem of curved in tracks, secondly, supporting leg is isosceles trapezoid, and supporting leg is provided with reinforcement connecting rod, strengthens connecting rod and is connected with supporting leg by the second bearing pin, not only installs and dismounting convenient transportation, goes back actv. and provide cost savings, improve integrally-built stability.

Detailed description of the invention
As shown in Figure 1,2,3, 4, a kind of single girder portal crane, comprise girder 1, be arranged on the supporting leg 3 of both sides below girder 1, be arranged on bottom linker 8 below supporting leg 3, be fixedly mounted on roller box 9 below bottom linker 8, be arranged on the dolly 2 above girder 1, the suspender 6 be connected with dolly 2 and operator's compartment 4, described girder 1 adopts the I-beam section of inverted triangle structure to be formed by connecting, and is connected between bottom linker 8 with roller box 9 by the first bearing pin 5.
Described supporting leg 3 supporting leg is isosceles trapezoid, supporting leg 3 is provided with and strengthens connecting rod 7, strengthens connecting rod 7 and is connected with supporting leg 3 by the second bearing pin 10.
The utility model under the premise that security is guaranteed, save cost, convenient transport and dismounting, in-site installation is convenient, and supporting leg 3, reinforcement connecting rod 7 all adopt steel pipe, be connected by the first bearing pin 5 between bottom linker 8 with roller box 9, convenient and swift, alerting ability is strong, operationally, run into the situation that track laying is bending, there will not be the phenomenon of rotation browsing rail to occur.Girder 1 adopts the I-beam section of inverted triangle structure to be formed by connecting, and change the structure of original two girder complexity, not only ensure that safety, and this structure can make movable joint, it is very convenient to transport and install.
