Abstract
The utility model discloses a kind of hoisting crane omnidistance guide piece of arm, in screw collar (1), be rotary with orienting lug (5), orienting lug (5) front end is provided with locking groove (6), and nylon slide block (2) is located in the locking groove (6), and orienting lug (5) rear end is provided with lock screw (4).To be a kind of telescopic boom that can make hoisting crane lateral bending phenomenon and hoisting crane simple and reliable for structure, easy to use occur with the omnidistance guide piece of arm stretching out Shi Buhui to the utility model.
Description
Technical field
The utility model relates to a kind of hoisting crane, particularly relates to a kind of hoisting crane omnidistance guide piece of arm.
Background technology
Telescopic boom is the critical component of wheel crane, directly influences the lifting performance of hoisting crane.Because telescopic boom is the socket join structure form, always has the gap between arm and the arm, more or less there is the lateral bending phenomenon in telescopic boom when stretching out, and is just also not obvious on medium and small tonnage hoisting crane.But appearance along with hoister in large tonnage, the full elongation of telescopic boom reaches more than the 50m, and along with lifting altitude increases, hoisting capacity increases, lateral bending phenomenon that telescopic boom occurs when stretching out lift heavy, more and more had a strong impact on hoisting crane in lifting performance and safety when long-armed.
The utility model content
Technical problem to be solved in the utility model provides a kind of telescopic boom of hoisting crane that makes and is stretching out the hoisting crane omnidistance guide piece of arm that the lateral bending phenomenon appears in Shi Buhui.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of hoisting crane omnidistance guide piece of arm, it is characterized in that: be rotary with orienting lug in screw collar, described orienting lug front end is provided with nylon slide block.
As a kind of improvement of the present utility model, described orienting lug rear end is provided with lock screw.
As a kind of improvement of the present utility model, described orienting lug front end is provided with locking groove, and described nylon slide block is located in the described locking groove.
Adopt the hoisting crane omnidistance guide piece of arm of technique scheme, every side is welded with two to three screw collars on the web of telescopic boom main body both sides, and orienting lug is spun in the screw collar by the screw thread of self.Instantly save telescopic boom when flexible, the nylon slide block on the orienting lug leans against down joint telescopic boom main body both sides all the time, and slides near on flanging place, bottom and the web that gusset support place is arranged in the telescopic boom main body, plays omnidistance directional tagging; Instantly save telescopic boom and be in when stretching state entirely, the telescopic boom both sides lean against down near the web of the both sides of joint telescopic boom main body afterbody by the nylon slide block on the orienting lug of back.
The hoisting crane that adopts technique scheme is with the omnidistance guide piece of arm, can well solve telescopic boom in the lateral bending phenomenon that occurs during long-armed lift heavy.
In sum, to be a kind of telescopic boom that can make hoisting crane lateral bending phenomenon and hoisting crane simple and reliable for structure, easy to use occur with the omnidistance guide piece of arm stretching out Shi Buhui to the utility model.
Description of drawings
Accompanying drawing 1 is orienting lug (not being with a locking groove) structural representation;
Accompanying drawing 2 is orienting lug (band locking groove) structural representations;
Accompanying drawing 3 is the utility model running condition scheme drawings.
The specific embodiment
Referring to accompanying drawing 1, be rotary with orienting lug 5 in the screw collar 1, screw 3 is fixed on nylon slide block 2 on the orienting lug 5, and orienting lug 5 rear ends are provided with lock screw 4, and lock screw 4 is used to regulate the locking after orienting lug 5 puts in place.
Referring to accompanying drawing 2, be rotary with orienting lug 5 in the screw collar 1, orienting lug 5 front ends are provided with locking groove 6, and screw 3 is fixed on nylon slide block 2 in the locking groove 6 on the orienting lug 5, and locking groove 6 prevents that nylon slide block 2 from sliding, and orienting lug 5 rear ends are provided with lock screw 4.
When carrying out the telescopic boom debugging, the orienting lug assembly 9,10,11,12 on the telescopic boom 7 screws in and is close to telescopic boom 8.In flexible and lift heavy process, if telescopic boom 8 heads then screw out a little with orienting lug assembly 9,10 to guiding block assembly 9,10 1 lateral deviations, again orienting lug assembly 11,12 is screwed in, and guarantee that orienting lug assembly 9,10,11,12 all is close to telescopic boom 8, continue flexible afterwards and the lift heavy debugging; If if telescopic boom 8 heads to guiding block assembly 11,12 1 lateral deviations, otherwise then.Debugging so repeatedly up to the lateral bending no longer of telescopic boom 8 in flexible and lift heavy process, with 9,10,11,12 lockings of orienting lug assembly, is fixed its position again.
Claims (3)
1, a kind of hoisting crane is characterized in that with the omnidistance guide piece of arm: be fixed in the screw collar (1) of arm both sides and be rotary with orienting lug (5), described orienting lug (5) front end is provided with nylon slide block (2).
2, a kind of hoisting crane according to claim 1 omnidistance guide piece of arm, it is characterized in that: described orienting lug (5) rear end is provided with lock screw (4).
3, a kind of hoisting crane according to claim 1 and 2 omnidistance guide piece of arm, it is characterized in that: described orienting lug (5) front end is provided with locking groove (6), and described nylon slide block (2) is located in the described locking groove (6).
