Abstract
The utility model discloses a reduce device of whole overall height degree, including hanging roof beam, dolly end beam tie -beam, dolly hoisting mechanism, dolly end beam and girder, it connects to hang roof beam and dolly hoisting mechanism to to hang the roof beam connects below dolly end beam tie -beam, dolly end beam tie -beam and dolly end beam are connected, the girder is located dolly end beam below. The utility model discloses atress, simple structure, convenient, the safe and reliable of manufacturing reach the reduction purpose of whole overall height degree by a wide margin when not changing bridge crane dolly high performance.
Description
Technical field
What the utility model related to a kind of hoist mechanism manufactures and designs field, specifically a kind of device reducing car load height.
Background technology
Domestic New overhead travelling crane adopts sinking end carriage usually, and the method reducing reductor height reduces hoisting crane car load height, these methods, stressed complexity, and easy stress is concentrated, and not easily manufacture, and falling head is little.
Utility model content
For the problems referred to above, the utility model is intended to adopt hoisting mechanism for trolley to be suspended on the middle a kind of device reducing car load height of method design of girder.
For realizing this technical purpose, scheme of the present utility model is: a kind of device reducing car load height, comprise hanging beam, dolly end carriage tie-beam, hoisting mechanism for trolley, dolly end carriage and girder, described hanging beam is connected with hoisting mechanism for trolley, and hanging beam is connected to below dolly end carriage tie-beam, described dolly end carriage tie-beam is connected with dolly end carriage, and described girder is positioned at below dolly end carriage.
As further program of the utility model: described the utility model adopts dolly end carriage tie-beam and hanging beam to be suspended in the middle of two girders by hoisting mechanism for trolley.
As further program of the utility model: described hanging beam is suspended on below dolly end carriage tie-beam by bearing pin.
As further program of the utility model: described dolly end carriage tie-beam and dolly end carriage adopt seamless welding.
Compared with prior art, the beneficial effects of the utility model are: the utility model is stressed, structure is simple, easily manufactured, safe and reliable, reach the object reducing significantly car load height while not changing OTC's trolley high performance.
Accompanying drawing explanation
Fig. 1 is overall schematic of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing basis and specific embodiment, the utility model is described in further details.
As shown in Figure 1, a kind of device reducing car load height of the utility model embodiment, comprise hanging beam 1, dolly end carriage tie-beam 2, hoisting mechanism for trolley 3, dolly end carriage 4 and girder 5, described hanging beam 1 is connected with hoisting mechanism for trolley 3, and hanging beam 1 is connected to below dolly end carriage tie-beam 2, described dolly end carriage tie-beam 2 is connected with dolly end carriage 4, and described girder 5 is positioned at below dolly end carriage 4.
As further program of the utility model: described the utility model adopts dolly end carriage tie-beam and hanging beam 1 to be suspended on by hoisting mechanism for trolley 3 in the middle of two girders 5.
As further program of the utility model: described hanging beam 1 is suspended on below dolly end carriage tie-beam 2 by bearing pin.
As further program of the utility model: described dolly end carriage tie-beam 2 adopts seamless welding with dolly end carriage 4.
The utility model welds orthogonal structure by tie-beam and two butt beams, hanging beam is connected with the whole lifting mechanism of dolly, be suspended on below tie-beam by hanging beam by bearing pin again, the lifting mechanism of whole like this dolly just suspended on below dolly end carriage.The version of this dolly, significantly can reduce the car load height of hoisting crane.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
