Abstract
The utility model relates to an improved electric single-beam lifter. Based on international LDP model, the utility model is modified as the steps: the movable location structure between an electrical calabash-shaped trolley and a main beam employs an auxiliary location method and structure of cincture reverse-hook and vertical stressed, which can improve working stability of the electric calabash-shaped trolley and enable the mechanical status of the model to be more rational. The utility model is especially suitable for improvement of mini-type electric single beam lifter required by many small factories.
Description
The utility model relates to crossbearer formula lifting technique.
At present, the mono beam overhead crane of domestic production and marketing has according to the classification of GB " JB/T 1360-94 ":
1. the electric block dolly is in the operation of girder lower flange, and electric block is arranged in the hoisting crane of girder below, and its product code name is LD;
2. electric block is installed in the hoisting crane (dolly of settling can only move at the upper limb of girder like this) on the angular trolley, and its product code name is LDP;
3. the electric block dolly is in the operation of girder lower flange, and electric block is arranged in the hoisting crane of girder side, and its product code name is LDC;
What wherein have the call is the LDP type.Because: the space availability ratio of its span and height is the highest in three kinds of above-mentioned types.It is especially suitable for small-sized factory building.
The main weak point of LDP type is: the attached structure that helps localization method of its electric block dolly, see that with regard to its mechanical state its electric block dolly mainly is to rely on its return pulley of choosing down to come the attached location that helps, and is still not ideal enough.
The purpose of this utility model is:
On the architecture basics of LDP type (the electric block dolly is in the operation of the upper limb of girder), propose a kind ofly to adopt that cincture is counter to collude the attached improvement behave that helps localization method and structure thereof of vertical stressed electric block dolly, make the mechanical state of this type more be tending towards reasonable.--this is directly connected to the workmanship of complete machine, that is: the stability of work, reliability and safety.
The utility model is achieved in that
Which comprises at least: be positioned at girder and the electric block that is positioned on the electric block dolly on the wheel crossbeam; The electric block dolly is positioned at the girder top, and its relies on the anti-support of colluding with trundle of cincture to make it stable; And, cincture upwards be positioned at girder on plane angle rail pad be close to and contact; Per two of cincture is one group, is provided with two groups at least, and arrangement is in line.
The utility model characteristics compared with the prior art:
1. because the utility model has adopted anti-vertical stressed assisted location method and the structure of colluding of cincture on the activity orientation structure of electric block dolly and girder, this has just created condition for the working stability that improves the electric block dolly;
2. owing to be to adopt the pattern of non-embedded plane angle rail pad (it is little wear and tear) to realize with the guide rail of cincture adapted in the utility model, this is with regard to again for to have created condition at the guide rail cost of the prerequisite decline low production of ensuring the quality of products.
Fig. 1 is the overall schematic of the utility model embodiment.
Fig. 2 is the K-K cross sectional drawing among Fig. 1, has also illustrated simultaneously the structural principle of Equipoising support apparatus of electric block dolly.
1: girder; 2: the electric block dolly; 3: electric block; 4: the wheel crossbeam; 5: with the identical wheel of wall limit guide rail; 6: drop hanger; 7: plane angle rail pad; 8: the I-shape guide rail; 9: trundle; 10: cincture.
Be not difficult to find out that it is the same with the type of GB LDP in the integral structure by Fig. 1 signal, available span and height space are bigger.
Be not difficult to find out in the local main cross sections structure (irrelevant conventional part is omitted with feature of the present invention) by Fig. 2 signal:
I-shape guide rail " 8 " should be on the position of girder " 1 " section disalignment, trundle " 9 " above the I-shape guide rail " 8 " is supporting the electric block dolly " 2 " of whole eccentric force, and the anti-vertical bearing force that colludes of left side cincture " 8 " just in time plays an equilibrium of forces effect to electric block dolly " 2 ".
The utility model is stated quite with existing skill on the difficulty of producing and assembling, and (mainly being the attached mechanical state that helps localization method and structure thereof of electric block dolly " 2 ") is higher than prior art on oeverall quality.
Claims (2)
1. improved type mono beam overhead crane,
Structurally which comprises at least:
Be positioned at the girder " 1 " on the wheel crossbeam " 4 " and be positioned at electric block " 3 " on the electric block dolly " 2 "; And electric block dolly " 2 " is positioned at the top of girder " 1 ", and its side is provided with electric block " 3 ",
It is characterized in that:
Its opposite side is provided with the anti-cincture that colludes " 10 "; And this cincture " 10 " upwards is close to plane angle rail pad " 7 " and is contacted.
2. according to the described a kind of improved type mono beam overhead crane of claim 1,
It is characterized in that:
Cincture " 10 ", per two is one group, and is provided with two groups at least, is in line to be arranged in the below of plane angle rail pad " 7 ".
