Problems solved by technology

[0003] The traditional boom lifting and positioning mechanism or device is generally divided into left and right parts, and the left and right positioning devices or mechanisms are separate. At least two manual operations are required to complete the positioning and unlocking of the boom lifting, and simultaneous automatic actions cannot be realized. May cause human error
Chinese patent document CN2009612340 discloses the lifting and lowering positioning mechanism of the paver leveling boom, which can realize the simultaneous movement of the left and right boom positioning mechanisms through the flexible shaft, but still requires manual intervention, and the structure is unreliable, and the flexible shaft is prone to failure, causing operational obstacles and cannot be achieved

Embodiment Construction

[0026] Figure 1 to Figure 8 It shows an embodiment of an automatic positioning device for lifting and lowering the boom of a paver according to the present invention. The device includes a boom hook 1 and a boom hook transmission mechanism. The lifting movement of the boom drives the boom hook 1 to locate and unlock the boom 2. The process of positioning and unlocking only needs to control the lifting of the boom 2. The operation is simple, safe and reliable; it is the left and right boom 2 of the paver respectively. By assembling a set of the positioning device of the present invention, the synchronous positioning and unlocking of the left and right big arms 2 can be easily realized without manual intervention, which can avoid misoperation and safety accidents, and has high reliability.

[0027] In this embodiment, the boom hook transmission mechanism includes a connecting rod 3 and an automatic telescopic reset mechanism 4. The automatic telescopic reset mechanism 4 is arra...

Abstract

The invention discloses an automatic positioning device in lifting of a large arm of a spreader. The automatic positioning device comprises a main-arm hook and a large-arm hook transmission mechanism, wherein the large-arm hook transmission mechanism is connected with the large-arm hook, and drives the large-arm hook to locate and de-lock a large arm according to the lifting motion of the large arm. The spreader-large arm lifting automatic positioning device has the advantages of simple and compact structure, convenient assembling, safety and reliability, and convenient operation, and is capable of automatically positioning and de-locking the large arm. The invention also discloses a spreader provided with the automatic positioning device in lifting of the large arm of the spreader.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an automatic positioning device for lifting and lowering a large arm of a paver and a paver. Background technique [0002] As an important road construction equipment, paver is widely used in practical engineering. During the construction of the screed of the paver, the boom oil cylinder of the boom is lowered to lower the screed to a position with a suitable distance from the ground, and when it is not working or in transition, it is necessary to put the screed through the boom The lifting cylinder lifts the screed to a certain height. In order to ensure the safety and reliability of the boom after lifting, usually when the screed is suspended on the boom, the boom is vertically aligned with the boom hook or the boom positioning pin. Positioning and restraint in the direction of the paver to prevent safety accidents caused by the falling of the screed when the paver is not ...
