Problems solved by technology

[0002] When assembling the chassis components of the load-bearing car body, the body needs to be hoisted or lifted before the assembly operation can be carried out. At present, the load-bearing car usually adopts the way of trolley wire transportation: the body is lifted by the self-propelled trolley spreader for chassis assembly, and the hoist The load ≤ 2T, while the protective load-bearing vehicles such as Mengshi have a curb weight of nearly 8 tons and a vehicle length of <7 meters. The use of trolley lines or EMC transportation cannot meet the assembly requirements, and there are certain safety risks

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 The heavy-duty work spreader shown in —7 comprises a walking track 1, a walking trolley arranged on the walking track 1 and a hoisting bracket 8, a walking bracket 17 is hoisted and fixed on the walking trolley, and the walking bracket 17 is connected with the hoisting bracket 8 Lifting device is arranged, and lifting device comprises electric hoist 6 and scissors fork 7. The walking trolley comprises a driving main vehicle 2 and a follow-up auxiliary vehicle 3 fixed with the driving main vehicle 2 by a connecting beam 18. The front end of the driving main vehicle 2 and the rear end of the following auxiliary vehicle 3 are respectively provided with a front anti-collision structure and a rear anti-collision structure. Hit the structure. The front anti-collision structure includes a front anti-collision beam 1...

Abstract

The invention discloses a heavy-load operation lifting appliance. The heavy-load operation lifting appliance comprises a travelling track, a travelling trolley arranged on the travelling track, and ahoisting support; a lifting device is connected between the travelling trolley and the hoisting support; the heavy-load operation lifting appliance further comprises two parallel guard rails, and thetwo guard rails are arranged below the left side and the right side of the hoisting support; and the hoisting support comprises a bearing support with the left side and the right side capable of beingsupported on guard rails. A main body of a self-propelled trolley is formed by the structure of a driving main trolley and a follow-up auxiliary trolley, the bearing capacity of the self-propelled trolley is improved, the main trolley and the auxiliary trolley are both provided with anti-collision structures, and stable operation of a production line is guaranteed; a trolley model switching supporting structure is designed on the hoisting support, and rapid trolley model supporting switching can be carried out according to the trolley model wheelbase by adopting a bearing moving and pin shaftlimiting mode; and when chassis assembling operation is carried out on a station, the hoisting support falls onto the guard rails, the guard rails can bear the load of fifteen tons, a good supportingand protecting effect is achieved, and the safety of heavy-load operation is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of vehicle assembly equipment, in particular to a heavy-duty work spreader. Background technique [0002] When assembling the chassis components of the load-bearing car body, the body needs to be hoisted or lifted before the assembly operation can be carried out. At present, the load-bearing car usually adopts the way of trolley wire transportation: the body is lifted by the self-propelled trolley spreader for chassis assembly, and the hoist The tool load is ≤2T, while the curb weight of protective load-bearing vehicles such as Mengshi is nearly 8 tons, and the vehicle length is less than 7 meters. The use of trolley wires or EMC transportation cannot meet the assembly requirements, and there are certain safety risks. Therefore how to solve the chassis assembly operation of large-tonnage, load-bearing body is the problem that faces at present. Contents of the invention [0003] The purpose of the present ...
