Abstract
The utility model provides an adjustment device for a crane boom pull rod. The adjustment device comprises a crane boom, an ear plate is connected with the crane boom, the other end of the ear plate is connected with a pull rod, an adjustment plate is arranged between the pull rod and the ear plate, and a plurality of adjustment holes are arranged on the adjustment plate. According to an inner pull rod connecting method provided by the utility model, the purpose of slightly adjusting a length of the inner pull rod via connecting the adjustment holes with different distances of the adjustment plate is reached, meanwhile a design of formation by an entire steel plate of the adjustment plate is adopted, the adjustment device has the advantages of high strength and excellent safety, stress of the inner pull rod and an outer pull rod is enabled to be uniform, and the crane boom is enabled to has the advantages of high balance, stability, safety and reliability.
Description
Technical field
The utility model relates to a kind of corollary apparatus of hoisting crane, specifically, relates to a kind of crane arm pull bar setting device.
Background technology
Hoisting crane is used to lift the big object of weight as large-scale hanging device, and wherein crane arm is the important parts that bear gravity, pulling force, tractive force, also is an important ring that is related to the weight-lifting equipment safety.Crane arm one end of hoisting crane is connected on the crane body, and the other end is connected on the crane body through draw-in bar and outside link, and crane arm can freely rotate like this, even does 360 ° of rotations around crane body.Draw-in bar and outside link play and ensure that crane arm is stable, stressed uniform vital function; This require draw-in bar and outside link can be evenly, force balance; Share the pulling force of crane arm jointly, have defective, discontinuity but existing draw-in bar is connected the mode of crane arm with outside link.At present; Draw-in bar and outside link all are to be connected to form in order by the otic placode at two ends and middle several pull bar; The length of otic placode and pull bar is fixed; So the length of draw-in bar and outside link can not arbitrarily change, and draw-in bar and outside link be not often because length matches and causes the crane arm discontinuity.This defective effect is to stability, safety and the reliability of crane arm.
The utility model content
The purpose of the utility model is to overcome the weak point of above-mentioned conventional art, and the crane arm pull bar setting device that a kind of draw-in bar and outside link are stressed evenly, have high balance, stability, safety and reliability is provided.
The purpose of the utility model reaches through following technical measures:
A kind of crane arm pull bar setting device comprises crane arm, and crane arm is connected with otic placode, and the other end of otic placode is connected with pull bar, it is characterized in that: be provided with regulating plate between said pull bar and the otic placode, said regulating plate is provided with several adjustment holes.
As a kind of concrete prioritization scheme, the quantity of said adjustment hole is three.
In the utility model; Regulating plate one end is connected with pull bar, and the other end is connected with otic placode through adjustment hole, can select different adjustment holes to be connected with otic placode arbitrarily; Because the distance between the hole of different adjustment holes and cylinder lever connecting rod is different, so can regulate the length of draw-in bar and outside link.
Owing to adopted technique scheme, compared with prior art, the utility model has the advantages that:
The draw-in bar connection mode that the utility model provides can be through connecting regulating plate the adjustment hole of different distance reach the purpose of fine setting draw-in bar length; Regulating plate adopts the design of monoblock steel plate forming simultaneously; Has the advantage that intensity is big, safety is good; Can make draw-in bar and outside link stressed evenly, make crane arm have high balance, stability, safety and reliability.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
Description of drawings
Accompanying drawing 1 is the integral structure scheme drawing of a kind of crane arm pull bar of the utility model setting device embodiment;
Accompanying drawing 2 is the partial enlarged drawings at A place in the accompanying drawing 1;
Accompanying drawing 3 be in the accompanying drawing 2 B-B to cutaway view;
Accompanying drawing 4 is structural representations of regulating plate among a kind of crane arm pull bar of the utility model setting device embodiment.
The specific embodiment
Embodiment: shown in accompanying drawing 1 to accompanying drawing 4, a kind of crane arm pull bar setting device comprises crane arm 3; Crane arm 3 is connected with otic placode 2; The other end of otic placode 2 is connected with pull bar 1, is provided with regulating plate 4 between pull bar 1 and the otic placode 2, and regulating plate 4 is provided with several adjustment holes 5.
In the present embodiment, the quantity of adjustment hole 5 is three.
In the utility model; Regulating plate 5 one ends are connected with pull bar 1, and the other end is connected with otic placode 2 through adjustment hole 5, can select different adjustment hole 5 to be connected with otic placode 2 arbitrarily; Because the distance between the hole of different adjustment hole 5 and cylinder lever connecting rod 1 is different, so can regulate the length of draw-in bar.
Claims (2)
1. crane arm pull bar setting device; Comprise crane arm (3), crane arm (3) is connected with otic placode (2), and the other end of otic placode (2) is connected with pull bar (1); It is characterized in that: be provided with regulating plate (4) between said pull bar (1) and the otic placode (2), said regulating plate (4) is provided with several adjustment holes (5).
