Description

Flexible overhead hoist of kinds of new forms of energy passenger train automobile body frameworks

Technical Field

The invention relates to lifting devices, in particular to a flexible lifting device for a body framework of a new energy bus.

Background

In the production of new energy passenger cars, the passenger car body light weight not only can reduce the passenger car energy consumption, but also can improve the dynamic property, the operation stability, the riding comfort and the driving safety of the passenger car, the passenger car body framework is an important bearing part of the passenger car, so to speak, the aluminum alloy body framework is generally adopted in the current new energy passenger car body light weight, the traditional hoisting mode is that the framework section bars are directly hooked on the body framework through the hoisting chain hooks of the travelling crane, the framework section bars are easy to gouge in the operation, the structural strength of the framework can be damaged if the operation is serious, the actual production needs cannot be met, and therefore kinds of flexible hoisting devices for the new energy passenger car body framework need.

Disclosure of Invention

The invention aims to solve the problem of providing a flexible lifting device for the body frame of new energy passenger cars, which can realize flexible lifting of the body frame, thereby meeting the actual production requirements of the new energy passenger cars.

The technical scheme includes that the new energy passenger car body framework flexible lifting device comprises lifting lugs, cross beams, lifting rings, lifting straps , lock catches, lifting hooks and lifting straps II, the lifting straps are sleeved in the lifting rings, the other end of the lifting straps is sleeved in the lock catches, the lock catches are buckled in positioning holes in the upper portion and the lower portion of the lifting lugs, the two ends of the cross beams are located in the middles of the lifting lugs and connected in a welding fixing mode, the lock catches are sleeved in circular holes in the upper ends of the lifting hooks, and the lifting straps II are sleeved in hook grooves of the lifting hooks.

When the automobile body framework is lifted, the lifting rings are sleeved in lifting chain hooks of the travelling crane, two lifting belts II (7) are sleeved on a main bearing beam of the automobile body framework respectively, the travelling crane moves horizontally to enable the cross beam (2) to be in a horizontal state, the lifting rings (3), the lifting belts (4), the lock catches (5), the lifting hooks (6) and the lifting belts II (7) to be in a mutual fastening state, so that the two lifting belts II (7) can be uniformly stressed, and the automobile body framework can be lifted safely.

FIG. 2 is a left side view of the flexible overhead hoist of the body frame of the kinds of new energy passenger cars.

1-lifting lug, 2-cross beam, 3-lifting ring, 4-hanging strip , 5-lock catch, 6-lifting hook and 7-hanging strip II.

Detailed Description

The invention is further illustrated in conjunction with the figures and the detailed description.

As shown in figure 1, the flexible lifting device for the body frame of the new energy passenger cars disclosed by the invention comprises lifting lugs (1) and cross beams (2).

As shown in figure 2, the lifting device comprises a lifting ring (3), a lifting belt (4), a lock catch (5), a lifting hook (6) and a lifting belt II (7), wherein the end (4) of the lifting belt is sleeved in the lifting ring (3), the end of the lifting belt is sleeved in the lock catch (5), the lock catch (5) is buckled in positioning holes at the upper part and the lower part of a lifting lug (1), two ends of a cross beam (2) are positioned in the middle of the lifting lug (1) and connected in a welding and fixing mode, the lock catch (5) is sleeved in a circular hole at the upper end of the lifting hook (6), and the lifting belt II.

When the lifting ring (3) is sleeved in a lifting chain hook of a travelling crane, two lifting straps II (7) are respectively sleeved on a main bearing beam of a car body framework, the travelling crane moves horizontally to enable the cross beam (2) to be in a horizontal state, and the lifting ring (3), the lifting straps (4), the lock catch (5), the lifting hook (6) and the lifting straps II (7) are slowly and vertically lifted to confirm that the lifting ring (3), the lifting straps (4), the lock catch (5), the lifting hook (6) and the lifting straps II (7) are in a mutual fastening state, so that.

Claims

The flexible lifting device for the body frame of the new energy passenger car is characterized by comprising a lifting belt (4), a lifting ring (3), a lock catch (5), a cross beam (2), a lock catch (5) and a lifting hook (6), wherein the end of the lifting belt (4) is sleeved in the lifting ring (3), the other end of the lifting belt is sleeved in the lock catch (5), the lock catch (5) is buckled in two positioning holes in the upper portion and the lower portion of the lifting hook (1), two ends of the cross beam (2) are located in the middle of the lifting hook (1) and connected in a welding and fixing.
