Embodiment Construction

[0046] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0047] In the present invention, unless stated otherwise, the used orientation words such as "up, down" are usually based on figure 1 The direction of the drawing is defined, and "the front end of the first lock hook and the front end of the second lock hook" refer to the two opposite ends of the first lock hook and the second lock hook respectively. In addition, in the hooking and disengaging process of the shackle assembly described, Figure 5a to Figure 6g The direction of the arrow in is the direction in which the first locking hook 1 approaches the second locking hook 2 mentioned in the present invention, and the opposite direction of the arrow is the dire...

Abstract

The invention discloses a locking hook assembly for hooking and locking a first object and a second object in relative movement. The locking hook assembly comprises a first locking hook and a second locking hook which are respectively arranged on the first object and the second object, and the first locking hook and the second locking hook are oppositely arranged and can elastically move, wherein by relative moment of the first object and the second object, the relative slip of the first locking hook along the second locking hook enables the first locking hook and / or the second locking hook to elastically move, so that the first locking hook can be selectively hooked and locked with or separated from the second locking hook. The invention also discloses a folding arm support of an engineering machine using the locking hook assembly. Sagging of a lower joint arm when the folding arm support is in a folded state can be effectively prevented. In addition, the invention also discloses concrete pumping equipment using the folding arm support of the engineering machine.

Description

technical field [0001] The invention relates to the field of hooking and locking two objects together, in particular to a locking hook assembly, a folding arm frame of construction machinery using the locking hook assembly and concrete pumping equipment using the folding arm frame. Background technique [0002] In various fields, there are many situations where two relatively moving objects need to be hooked together. For example, in the folding arm frame of concrete pumping equipment, after the work is completed, two adjacent arm sections need to be folded together to facilitate transportation. However, if figure 1 As shown, the first arm 61 is hinged at the end of the second arm 62 and rotates relative to the second arm 62 by driving the oil cylinder 7 . After the work of folding the boom is completed, the first arm 61 needs to be folded under the second arm 62 . Due to the effect of gravity, the first arm 61 may move downward away from the second arm 62 during transpor...
