Embodiment Construction

[0044] exist figure 1 , 2 , 3, and 4, the present invention discloses an elastic support mobile crane, and the front elastic support pad 6, the middle elastic support pad 8 and the rear elastic support pad with extrusion resistance are arranged on the lower bottom surface supported by the crane 11. This elastic support pad is used to balance unexpected horizontal forces that may occur when lifting a group of cars without unhooking. The dynamics and probability that this unexpected horizontal force produces can increase along with the group compartment quantity that lifts and does not unhook. This force will damage the frame frame structure of the crane, and cause serious harm to the operation safety and reliability of the crane.

[0045] Four elastically supported mobile carriage units 3 of the present invention form a set of single-frame carriages to lift one compartment; multiple sets of single-frame carriages can form multi-frame carriages to lift multiple sections witho...

Abstract

The invention relates to an elastic support mobile car lifter. The supported lower bottom of the car lifter is provided with an elastic support pad for balancing accident horizontal force, wherein the elastic support pad has extrusion-resistant performance. The car lifter can lift single-link carriages and multi-link unhooked united carriages. An air cushion disc is adopted as a walking mechanism of a mobile car lifting unit. The upper end and the lower end of a lifting screw are in a double-self-aligning hanging structure with a self-aligning roller step bearing so that the stress state of the lifting screw is improved. A speed reducer is elastically connected with an engine base through an elastic combiner to deliver torques. Apart from a main guiding wheel and a guiding stop rod, a lifting pulley is also provided with a sidewise guide wheel for guiding so that the carrying capacity of the car lifter on the sidewise horizontal force is improved. The invention has the advantages that the elastic support mobile car lifter can be combined into a single-car lifter for lifting single-link carriages and a multi-car lifter for lifting multi-link unhooked united carriages; by adopting the air cushion disc as the walking mechanism of the mobile car lifting unit, the elastic support mobile car lifter has labor saving of movement and flexible alignment; and the elastic support mobile car lifter omits a telescopic car lifting arm, simplifies a mechanism, and reduces the manufacturing cost.

Description

technical field [0001] The invention relates to a crane for disassembling and maintaining rail transit vehicles, in particular to a mobile crane with elastic support. Background technique [0002] The underground car crane is suitable for disassembling and maintaining group carriages without unhooking. It has a complex structure and high cost, and a series of large-scale pits need to be built. The above-ground vehicle lifting machine is mainly used for the disassembly and maintenance of a single carriage of rail transit vehicles. It has a simple structure and low cost. Some occasions require the group carriages that are not decoupled to be disassembled and maintained by the low-cost ground car machine with simple structure, but the existing ground car machine is difficult to meet this requirement. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies of the existing above-ground trolleys, the present invention provides an elastically sup...
