Description
Technical field
The utility model relates to crane field, particularly relates to a kind of without clump weight balance crane.
Background technology
At present, lifting industry inner equilibrium is hung and is adopted counterweight more, when adopting counterweight, the large arm of balance crane is equipped with clump weight away from one end of ceiling mounted arm, and therefore, one end that large arm is equipped with clump weight unavoidably will be extended, cause Applicable scope little, be not suitable for being arranged on less space, the weight of self is also heavier, removes and unloads inconvenience.
Summary of the invention
The utility model be overcome in prior art take up room greatly with clump weight balance crane, Applicable scope is little, own wt is heavy deficiency, and provide a kind of take up room little, Applicable scope is large, own wt is little without clump weight balance crane.
The utility model provides a kind of large arm comprising base without clump weight balance crane, be vertically fixed on column on base, be horizontally installed on column top, the two ends of large arm lay respectively at the both sides of column, one end of large arm is connected with ceiling mounted arm, ceiling mounted arm is connected with suspension hook away from one end of large arm, large arm is provided with the first spring away from one end of ceiling mounted arm, base or ground are provided with the second spring, are connected between the first spring with the second spring by retractor device.
Retractor device is electric expansion bar.
Beneficial effect:
1, the utility model provide without clump weight balance crane, adopt spring replace clump weight, decrease the own wt of balance crane, conveniently remove and unload.
2, retractor device is provided with between the first spring and the second spring, by the pulling force of adjustable first spring of retractor device and the second spring, the goods of Different Weight capable of hoisting, and large arm connect the first spring not need to stretch out column oversize in one end, take up room less, can be arranged on less space, Applicable scope is wider.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation without clump weight balance crane embodiment 1 of the utility model;
Fig. 2 is a kind of structural representation without clump weight balance crane embodiment 2 of the utility model.
Detailed description of the invention
Embodiment 1: as shown in Figure 1, a kind of large arm 3 comprising base 1 without clump weight balance crane, be vertically fixed on column 2 on base 1, be horizontally installed on column 2 top, the two ends of large arm 3 lay respectively at the both sides of column 2, one end of large arm 3 is connected with ceiling mounted arm 4, ceiling mounted arm 4 is connected with suspension hook 5 away from one end of large arm 3, large arm 3 is provided with the first spring 6 away from one end of ceiling mounted arm 4, and base 1 or ground are provided with the second spring 8, first bullet 6 spring and are connected by retractor device 7 with between the second spring 8.
Need sling goods time, the first spring 6 and the second spring 8 are linked together by retractor device 7, regulate retractor device 7 according to the weight of required goods of slinging, thus regulate the pulling force of the first spring 6 and the second spring 8.
Adopt spring to replace clump weight, decrease the own wt of balance crane, conveniently remove and unload.
Retractor device 7 is provided with between first spring 6 and the second spring 8, by the pulling force of adjustable first spring 6 of retractor device 7 and the second spring 8, the goods of Different Weight capable of hoisting, and large arm 3 connect the first spring 6 not need to stretch out column 2 oversize in one end, take up room less, can be arranged on less space, Applicable scope is wider.
Embodiment 2: as shown in Figure 2, a kind of large arm 3 comprising base 1 without clump weight balance crane, be vertically fixed on column 2 on base 1, be horizontally installed on column 2 top, the two ends of large arm 3 lay respectively at the both sides of column 2, one end of large arm 3 is connected with ceiling mounted arm 4, ceiling mounted arm 4 is connected with suspension hook 5 away from one end of large arm 3, large arm 3 is provided with the first spring 6 away from one end of ceiling mounted arm 4, and base 1 or ground are provided with the second spring 8, first spring 6 and are connected by retractor device 7 with between the second spring 8.
Retractor device 7 is electric expansion bar, adopts electric expansion bar to avoid manual regulation, uses more convenient and quicker.
Need sling goods time, first spring 6 and the second spring 8 are linked together by electric expansion bar, weight according to required goods of slinging regulates electric expansion bar, thus regulate the pulling force of the first spring 6 and the second spring 8, spring is adopted to replace clump weight, decrease the own wt of balance crane, conveniently remove and unload.
Electric expansion bar is provided with between first spring 6 and the second spring 8, by the pulling force of adjustable first spring 6 of electric retractable bar and the second spring 8, the goods of Different Weight capable of hoisting, and large arm 3 connect the first spring 6 not need to stretch out column 2 oversize in one end, take up room less, can be arranged on less space, Applicable scope is wider.
