Abstract
The utility model relates to a crawler amplitude device of a crawler-type crane, belonging to the field of construction machinery. A central device of a truck frame has an amplitude cylinder. A front amplitude bracket and a back amplitude bracket are respectively fixed at the front side and the back side of the truck frame. Both sides of the front amplitude bracket and the back amplitude bracket are respectively provided with a left crawler frame and a right crawler frame that can move laterally. The distance between the left crawler frame and the right crawler frame can be adjusted according to the operating stroke of the amplitude cylinder, so that the width of the crawler-type crane can be adjusted while the crawler works and the crawler-type crane lifts heavy objects, so as to considerably improve the stability and the safety of the operation of the crawler-type crane.
Description
Technical field
The utility model relates to a kind of crawler crane crawler belt luffing device, belongs to engineering machinery field.
Background technology
At present, be one of major product of construction machinery and equipment at the construction machinery industry crawler crane, the effect of track unit in the crawler crane complete machine is: have driving functions and supporting complete machine and lift heavy thing weight.Under the lift heavy state, more stable in order to make hoisting crane, needs increase the spacing of both sides crawler belt.Existing hoisting crane track frame is in the processing and manufacturing process, fix in the spacing of the left and right sides track frame of car load support both sides for device, can't regulate in the course of the work, when running into big workpiece of lifting or special road surface situation, can't in time adjust the spacing of crawler belt, can cause damage to hoisting crane, also increase operator's labour intensity simultaneously.
Summary of the invention
The purpose of this utility model provides a kind of crawler belt luffing device, be fixed with forward and backward luffing support at vehicle frame forward and backward, device has transversely movable left track frame, right-hand track chiain frame respectively in the both sides of preceding luffing support and back luffing support, to overcome the deficiencies in the prior art part.
The purpose of this utility model realizes with following technical scheme: a kind of crawler belt luffing device, it is characterized in that: this mechanism comprises vehicle frame and the amplitude oil cylinder of device in the middle part of vehicle frame, luffing support before the front portion of vehicle frame is fixed with, the rear portion of vehicle frame is fixed with back luffing support, and device has transversely movable left track frame, right-hand track chiain frame respectively in the both sides of preceding luffing support and back luffing support.
The utility model has the advantages that: this crawler belt luffing device is simple in structure, do not add other parts, the spacing of utilizing the forced stroke of amplitude oil cylinder to regulate the right-hand track chiain frame, width when having increased crawler crane crawler travel, hoisting heavy operation, thus significantly improved the job stabilization and the safety of crawler crane.
Description of drawings
The utility model is described in further detail to reaching embodiment below in conjunction with accompanying drawing:
Accompanying drawing is the utility model structural representation:
Among the figure: 1, vehicle frame, 2, amplitude oil cylinder, 3, preceding luffing support, 4, back luffing support, 5, left track frame, 6, the right-hand track chiain frame.
The specific embodiment
As shown in the figure: a kind of crawler belt luffing device, comprise vehicle frame 1 and device amplitude oil cylinder 2 at the vehicle frame middle part, luffing support 3 before the front portion of vehicle frame 1 is fixed with, the rear portion of vehicle frame 1 is fixed with back luffing support 4, device has transversely movable left track frame 5, right-hand track chiain frame 6 respectively in the both sides of preceding luffing support 3 and back luffing support 4, width when it has increased crawler crane crawler travel, hoisting heavy operation, thus significantly improved the job stabilization and the safety of crawler crane.
