Abstract
The utility model discloses a crawler crane boom left and right derricking gear which comprises a jack mechanism, a knuckle bearing, a main shaft, a main vertical plate and a U-shaped plate, wherein the jack mechanism is installed at one end of the derricking gear and the knuckle bearing is installed at the end of the derricking gear corresponding to the jack mechanism. The utility model overcomes the problem that the leftward and rightward deviation correcting capacity of the existing piling machine is poor and ensures the quality of piling work.
Description
Technical field
The utility model relates to construction machine, relates in particular to a kind of crawler crane boom left and right sides luffing mechanism.
Background technology
In piling work, stake (the concrete square pile that requirement is driven underground, pile tube, steel pipe pile) must assurance vertically bury, error must not surpass 5%, guarantee error in allowed limits, just must guarantee with 2, the one, the workyard is very smooth, the 2nd, pile driver must have enough centering capacities, but actual engineering construction place is a mud ground, and ground-surface planeness is difficult to guarantee, therefore deviation occurring is inevitable, in this case, the centering capacity that improves pile driver is exactly very necessary, and existing pile driver is because the restriction of project organization, enough at the working direction centering capacity, and almost not having centering capacity at left and right directions, its consequence is a machine at left and right directions as deviation takes place, and then can't correct, lobe appears in last the result broken or pile body of pile crown often, has had a strong impact on construction quality.
The utility model content
The purpose of this utility model provides a kind of problem that can overcome existing stake machine left and right directions centering capacity deficiency, and guarantees the crawler crane boom left and right sides luffing mechanism of pilework quality.
The technical scheme that the utility model is adopted for achieving the above object is: a kind of crawler crane boom left and right sides luffing mechanism, comprise lifting body, oscillating bearing, main shaft, main riser and U template, lifting body is installed on an end of luffing mechanism, and oscillating bearing is installed in the end that luffing mechanism corresponds to lifting body.
Described lifting body is the lifting hydraulic ram.
Described U template links to each other with oblong aperture on the main riser respectively by main shaft.
A kind of crawler crane boom of the utility model left and right sides luffing mechanism has overcome the problem of existing stake machine left and right directions centering capacity deficiency, thereby guarantees the pilework quality.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a kind of crawler crane boom of the utility model left and right sides luffing mechanism structural representation.
The specific embodiment
As shown in Figure 1, crawler crane boom left and right sides luffing mechanism, comprise 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 luffing mechanism, luffing mechanism can be moved up and down, oscillating bearing 2 is installed in the other end of luffing mechanism, make luffing mechanism wigwag motion within the specific limits, this lifting mechanism 1 is the lifting hydraulic ram, 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 with crawler crane boom left and right sides luffing mechanism respectively by main shaft 3, on ground when very smooth, the oil cylinder piston jack-up that makes progress, make main shaft 3 be in the middle part of main riser 4 oblong aperture, when about ground not at ordinary times, oil cylinder piston moves downward or upward, make a machine principal arm remain plumbness, because an end of crawler crane boom left and right sides luffing mechanism is kept in motion, so the two ends of luffing mechanism all must be by the dress oscillating bearing, unaffected to guarantee its motion, and the fastness and the safety of its crawler crane boom left and right sides luffing mechanism are guaranteed.
Claims (3)
1. crawler crane boom left and right sides luffing 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 luffing mechanism, and oscillating bearing is installed in the end that luffing mechanism corresponds to lifting body.
2. a kind of crawler crane boom according to claim 1 left and right sides luffing mechanism, it is characterized in that: described lifting body is the lifting hydraulic ram.
