Description

Adjustable engineering machinery engine lifting balancing device

Technical field

The utility model relates to the lifting machine field, relates in particular to a kind of adjustable engineering machinery engine lifting balancing device that is applied to the driving engine lifting.

Background technology

The driving engine of construction machinery and equipment needs repairing or when changing; In integral hoisting dismounting and fitting process; Center-of-gravity position and equilibrium point are difficult to grasp; Bring certain difficulty for dismounting and assembling and positioning work, invent center of gravity and equilibrium point that this device can be found out driving engine fast and easily, create advantage very easily for the accurate installing and locating of driving engine.

Summary of the invention

The utility model technical matters to be solved is, is the technical deficiency to above-mentioned existence, provides a kind of simple in structure, can accurately find out the center of gravity and the equilibrium point of driving engine, the convenient lifting balancing device of implementing lifting.

Technical scheme below its technical matters that solves the utility model adopts:

Adjustable engineering machinery engine lifting balancing device, it is characterized in that: include the sleeve pipe of the rectangle of a strip, the centre of sleeve pipe is the hollow structure of rectangle; And penetrating the expansion link of rectangle respectively at the two ends of sleeve pipe, expansion link can be movable in sleeve pipe, wherein; One side surface of sleeve pipe is provided with the circular hole that a row waits branch to arrange; The surface of expansion link also is provided with the circular hole that the five equilibrium identical with the sleeve surface spacing arranged, and in sleeve pipe and the cooresponding circular hole of expansion link, also is inserted with dowel bolt and fixes; The top of described sleeve pipe also is welded with link plate.

In such scheme, described link plate is a triangular structure, and its base and Socket welding are connected together, and its position, summit is provided with hole for hoist, is used for being connected with suspension hook.

The principle of the utility model is:

This device is made up of fixing rectangle sleeve pipe and rectangle telescopic rod, and the perforation at triangle link plate top, top is the connecting shackle hanging point, and bottom rectangle expansion link stretches out the exterior any hole of rectangle sleeve pipe, can be connected with driving engine with steel rope or other suspenders.The rectangle expansion link can move by transversal stretching in the rectangle sleeve pipe, the length distance of stretching out according to the adjustment of the lifting point of driving engine.The rectangle sleeve pipe adopts steel plate to be welded, and the rectangle of hollow is made in the cross section, its objective is to make this device can bear bigger bending strength, and the centre is drilled with the perforation of a round diameter 30, presses five equilibrium respectively and arranges.The cross section of rectangle expansion link is a rectangle; Can move at the rectangular sleeve inner telescoping tube; On the rectangle expansion link, also be processed with the hole of arranging with the same diameter of rectangle sleeve pipe and five equilibrium, the pitch-row on pitch-row and the expansion link is consistent, has alleviated single-piece weight; Also be convenient to be connected with pivot pin, fix flexible length with the expansion link of rectangle.

The main beneficial effect of the utility model is: this utility model is simple in structure, can accurately find out the center of gravity and the equilibrium point of driving engine, and is convenient to driving engine enforcement lifting.

The specific embodiment

In order to understand the utility model better, below in conjunction with embodiment and accompanying drawing the technical scheme of the utility model is done further explanation, referring to Fig. 1:

Adjustable engineering machinery engine lifts balancing device, includes the sleeve pipe 1 of the rectangle of a strip, and the centre of sleeve pipe 1 is the hollow structure of rectangle; And penetrating the expansion link 2 of rectangle respectively at the two ends of sleeve pipe 1, expansion link 2 can be movable in sleeve pipe 1, wherein; One side surface of sleeve pipe 1 is provided with the circular hole that a row waits branch to arrange; The surface of expansion link 2 also is provided with the circular hole that the five equilibrium identical with sleeve pipe 1 surface spacing arranged, and in sleeve pipe 1 and expansion link 2 cooresponding circular holes, also is inserted with dowel bolt 4 and fixes with nut 6; The top of described sleeve pipe 1 also is welded with link plate 3.

In the present embodiment, described link plate 3 is a triangular structure, its base and sleeve pipe 1 weld together, and its position, summit is provided with hole for hoist 5, is used for being connected with suspension hook.

When using this device, elder generation according to the hoisting point position on the driving engine, adjusts the collapsing length of rectangle expansion link 2 with this device; Be connected the hole, garden at two ends on the lifting point of driving engine with snap ring and steel rope; According to the center-of-gravity position and the equilibrium point of driving engine, adjust the extension elongation at expansion link 2 two ends before the lifting, and dowel bolt 4 is put into knock hole; Using nut 6 lockings can connector bushing 1 be whole with expansion link 2, and driving engine remained on balance position when lifted driving engine this moment.

This apparatus features is: can be applicable to the big-block engine of various construction machinery and equipments, lifting dismounting and installing and locating work make driving engine when lifting, remain at the position of balance, are convenient to the carrying out of installing and locating and dismantlement work.The intention point of inventing this device is to find out fast and easily the center of gravity and the equilibrium point of driving engine, creates advantage very easily for the accurate installing and locating of driving engine.Especially when construction machinery and equipment need be changed the driving engine of different profiles, make driving engine balance hoisting and locating accurately, more show its unique effect.

The above disclosed preferred embodiment that is merely the utility model can not limit the interest field of the utility model certainly with this, so according to the equivalence variation that the utility model claim is done, still belong to the protection domain of the utility model.
