Abstract

The invention discloses a left and right luffing mechanism for an arm support of a crawler crane, which comprises a jacking mechanism, a knuckle bearing, a main shaft, a main riser plate and a U-shaped plate, wherein the jacking mechanism is installed on one end of the luffing mechanism, and the knuckle bearing is installed on one end of the luffing mechanism opposite to the jacking mechanism. The left and right luffing mechanism for the arm support of the crawler crane overcomes the problem that the traditional piling machine has a poor deviation rectifying capability in the left and right direction, thereby ensuring the quality of piling work.

Description

Crawler crane boom left and right sides jib lubbing mechanism

Technical field

The present invention relates to construction machine, relate in particular to a kind of crawler crane boom left and right sides jib lubbing mechanism.

Background technology

In piling work, the stake (concrete square pile, pile tube, steel pipe pile) that requires to be driven underground must vertically be buried in assurance; Error must not surpass 5%, guarantee error in allowed limits, just must guarantee with 2, and the one, the construction plant is very smooth; The 2nd, pile driver must have enough centering capacities, but actual engineering construction place is a mud ground, and the planeness on ground is difficult to guarantee, therefore deviation occurs and be inevitable; In this case, the centering capacity that improves pile driver is very necessary, and existing pile driver is because the restriction of project organization; Enough at the direction of advance centering capacity, and almost do not have centering capacity at left and right directions, its consequence be a machine at left and right directions as deviation takes place; Then can't correct, lobe appears in last the result broken or pile body of pile crown often, has had a strong impact on workmanship.

Summary of the invention

The purpose of this invention is to provide a kind of problem that can overcome existing stake machine left and right directions centering capacity deficiency, and guarantee the crawler crane boom left and right sides jib lubbing mechanism of pile works quality.

The present invention for realizing the technical scheme that above-mentioned purpose adopted is: a kind of crawler crane boom left and right sides jib lubbing mechanism; Comprise lifting body, oscillating bearing, main shaft, main riser and U template; Lifting body is installed on an end of jib lubbing mechanism, and oscillating bearing is installed in the end that jib lubbing mechanism corresponds to lifting body.

Said lifting body is the up-down hydraulic jack.

Said U template through main shaft respectively with main riser on oblong aperture link to each other.

A kind of crawler crane boom of the present invention left and right sides jib lubbing mechanism has overcome the not enough problem of existing stake machine left and right directions centering capacity, thereby guarantees the pile works quality.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described further.

Fig. 1 is a kind of crawler crane boom of the present invention left and right sides jib lubbing mechanism structural representation.

The specific embodiment

As shown in Figure 1, crawler crane boom left and right sides jib lubbing mechanism comprises lifting body 1, oscillating bearing 2, main shaft 3, main riser 4 and U template 5; Lifting body 1 is installed in an end of jib lubbing mechanism, and jib lubbing mechanism can be moved up and down, and oscillating bearing 2 is installed in the other end of jib lubbing mechanism; Jib lubbing mechanism can be vacillated now to the left, now to the right within the specific limits, and this elevating mechanism 1 is the up-down hydraulic jack, and the piston rod 6 of oil cylinder links to each other with U template 5; 5 on U template links to each other with oblong aperture on the main riser 4 through main shaft 3; On ground when very smooth, the oil cylinder piston jack-up that makes progress makes main shaft 3 be in the middle part of main riser 4 oblong aperture; Because an end of crawler crane boom left and right sides jib lubbing mechanism is kept in motion; So the dress oscillating bearing all must be pressed in the two ends of jib lubbing mechanism, and is unaffected to guarantee its motion, and the fastness and the safety of its crawler crane boom left and right sides jib lubbing mechanism are guaranteed.

Claims (3)

1. crawler crane boom left and right sides jib lubbing mechanism; It is characterized in that: comprise lifting body, oscillating bearing, main shaft, main riser and U template; Lifting body is installed on an end of jib lubbing mechanism, and oscillating bearing is installed in the end that jib lubbing mechanism corresponds to lifting body.
2. a kind of crawler crane boom according to claim 1 left and right sides jib lubbing mechanism, it is characterized in that: said lifting body is the up-down hydraulic jack.
