Abstract
A kind of low headroom double girder crane dolly, comprise the two electronic end carriages that are connected with factory building girder, two electronic end carriages connect by gate-type carrier bar, on gate-type carrier bar, are fixed with electric block, electronic end carriage hangs on girder lower flange, and gate-type carrier bar top is suitable with girder upper cover height.Low headroom double girder crane dolly of the present utility model, electronic end carriage is arranged on the lower flange of girder, so just reduced the installation of electronic end carriage, avoided the installation inconvenience bringing because of factory building roof limitation in height in installation process, electric block hangs on gate-type carrier bar, and gate-type carrier bar top flushes with girder overhead height, so the not super girder height of the setting height(from bottom) of electric block, be convenient to install, also improved to greatest extent effective hoisting depth of electric block simultaneously.
Description
Technical field
The utility model belongs in factory building uses lifting field, relates in particular a kind of low headroom double girder crane dolly that installing space improves room for promotion simultaneously to greatest extent that reduces.
Background technology
In short factory building, set up single-beam crane lifting altitude inadequate, and it is inadequate to the spatial altitude of roof truss to set up double girder crane crane girder, have a strong impact on the installation of lifting crane, and the usable height of lifting is restricted, can not meet operating needs, give and produce and carry and bring very large inconvenience.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of setting height(from bottom) that reduces original crane carriage, is convenient to install, and improves to greatest extent the low headroom double girder crane dolly of room for promotion simultaneously.
For solving the problems of the technologies described above, the utility model provides a kind of low headroom double girder crane dolly, comprise the two electronic end carriages that are connected with factory building girder, described two electronic end carriages connect by gate-type carrier bar, on described gate-type carrier bar, be fixed with electric block, described electronic end carriage hangs on girder lower flange, and described gate-type carrier bar top and girder upper cover height adapt.
Preferably, described gate-type carrier bar top flushes with girder upper cover.
Preferably: described electric block hangs on gate-type carrier bar.
Preferably, described gate-type carrier bar two ends are provided with maintenance platform and guardrail near electronic end carriage position.
A kind of low headroom double girder crane dolly of technical solutions of the utility model, compared with prior art has following some advantage:
1, change the original mounting means that electronic end carriage is arranged to girder top for electronic end carriage is arranged on the lower flange of girder, so just reduced the setting height(from bottom) of double girder crane, making, in the little factory building of crane girder superjacent air space, double girder crane is installed becomes possibility.
2, gate-type carrier bar top flushes with girder top cover height, the installation inconvenience of having avoided gate-type carrier bar to bring because of factory building roof limitation in height in installation process, and the while has also been improved the setting height(from bottom) of gate-type carrier bar to greatest extent;
3, electric block hangs on gate-type carrier bar, gate-type carrier bar top flushes with girder overhead height, the not super girder height of the setting height(from bottom) of electric block like this, be convenient to install, also improved to greatest extent effective hoisting depth of electric block simultaneously, effective hoisting depth of electric block is the installation site to electric block by ground, and the height of lifting can be down to the height of girder;
4, maintenance platform and guardrail are set on tie-beam, while being convenient to electric block, electronic end carriage etc. to keep in repair, repairman can have standpoint, does not need to set up the ascending tools such as ladder.

The specific embodiment
Below in conjunction with Figure of description, the technical solution of the utility model and structure are described, so that those skilled in the art understand.
As shown in Figure 1 to Figure 3, a kind of low headroom double girder crane dolly, comprise the two electronic end carriages 2 that are connected with factory building girder 1, described two electronic end carriages 2 connect by gate-type carrier bar 4, on described gate-type carrier bar 4, be fixed with electric block 5, described electronic end carriage 2 hangs on girder 1 lower flange, and described gate-type carrier bar 4 tops and girder 1 upper cover height adapt.
Described gate-type carrier bar 4 tops flush with girder 1 upper cover.
Described electric block 5 hangs on gate-type carrier bar 4.
Described gate-type carrier bar 4 two ends are provided with maintenance platform 7 and guardrail 6 near electronic end carriage 2 positions.
A kind of low headroom double girder crane dolly of technical solutions of the utility model, electronic end carriage 2 is arranged at respectively on the lower flange of symmetrical two girders 1, then gate-type carrier bar 4 is arranged between two electronic end carriages 2, the overhead height that guarantees gate-type carrier bar 4 flushes with the overhead height of girder 1, be convenient to the installation of gate-type carrier bar 4, avoided gate-type carrier bar 4 excessive height or bumped or interference with factory building top higher than girder 1 height, also improved to greatest extent the height of gate-type carrier bar 4 simultaneously, at gate-type carrier bar 4 tops, hang electric block 5, so just guaranteed that electric block 5 has promoted the height of girder 1 thickness, promote to greatest extent electric block 5 and can promote the usable height of slinging.
Above-mentionedly by reference to the accompanying drawings utility model is exemplarily described; obviously the utility model specific implementation is not subject to the restrictions described above; as long as this non-essential improvement that has adopted method design of the present utility model and technical scheme to carry out; or without improving, the design of utility model and technical scheme are directly applied to other occasions, all within protection domain of the present utility model.
