Problems solved by technology

Some construction machinery products require different attachments for construction under different working conditions, and there are many types of attachments, which are laborious to replace. In the early days, some construction machinery replacement attachments were manually replaced, which required multiple people to operate at the same time and was inefficient.

Embodiment

[0026] The hydraulic quick-change mechanism for attachments of the present invention includes an attachment connecting frame 1, a long shaft 2, a long shaft locking mechanism 112, a quick-change connecting rod mechanism 3, and a quick-change oil cylinder 4.

[0027] The attachment frame 1 is composed of a side plate 11, a lower support shaft 12, a left guide shaft sleeve 13, a hinge frame 14, a mounting support 15, a right guide shaft sleeve 16, a cylinder base 17, a side plate reinforcement plate 18, and a lifting lug 19. , The upper supporting shaft 110 and the connecting plate 111 are composed. Among them, the upper support shaft 110 and the lower support shaft 12 are arranged in parallel. The upper support shaft 110 and the lower support shaft 12 are provided with side plates 11 at both ends, and the upper part of each side plate 11 is provided with a long shaft 2 or a connector. With grooves. A long shaft locking mechanism 112 is provided outside the side plate 11 at the co...

Abstract

The invention discloses a hydraulic quick-change mechanism for an accessory. The hydraulic quick-change mechanism comprises an accessory connecting frame, a quick-change oil cylinder, a quick-change connection rod mechanism and a long shaft locking mechanism; the accessory connecting frame comprises side plates, a lower supporting shaft, a first guide shaft sleeve, installation supports, a secondguide shaft sleeve and an upper supporting shaft; the two ends of the upper supporting shaft and the two ends of the lower supporting shaft are connected through the side plates correspondingly, and each side plate is provided with a groove; locking mechanisms are arranged on the outer sides of the side plates; the lower supporting shaft is provided with installation supports distributed in a triangular shape, the first guide shaft sleeve and the second guide shaft sleeve; the quick-change connection rod mechanism is limited and installed on the accessory connecting frame through the installation supports, the first guide shaft sleeve and the second guide shaft sleeve; the quick-change connection rod mechanism rotates by a small angle, thus, large-stroke sliding can be obtained, the mechanism change action time is shorter, and the whole machine operating efficiency is improved; and the axis of a quick-change oil cylinder and the quick-change connection rod mechanism are located on thesame plane, additional torque is not generated during change action, and the quick-change mechanism is long in service life and high in reliability.

Description

Technical field [0001] The invention relates to a quick replacement mechanism for attachments of construction machinery, in particular to a hydraulic quick replacement mechanism for attachments, belonging to the technical field of construction machinery. Background technique [0002] At present, construction machinery is widely used in a series of engineering constructions such as ports, building construction and municipal administration. Some construction machinery products require different attachments for construction under different working conditions, and there are many types of attachments that are laborious to replace. In the early days, some construction machinery replacement attachments were replaced manually, which required multiple people to operate at the same time and was inefficient. In order to improve the efficiency and adaptability of construction machinery, there is an urgent need for a mechanism that is efficient, convenient and can be independently operated by...
