Embodiment Construction
[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0026] see Figure 1-Figure 4, a hydraulic quick-change connector for an excavator, comprising a main structural plate 1, the number of the main structural plate 1 is two, a connecting rod 2 is fixedly installed on one side of the main structural plate 1 near both ends, and the main structural plate 1. Connected to each other by connecting rods 2, a fixed plate 3 is fixedly installed on one side of the main structural plate 1 and loca...

The invention relates to the technical field of special engineering vehicles, and discloses a hydraulic quick-change connector for an excavator. When the piston sleeve is in the initial position state, the catheter is blocked and cannot be circulated, so that the catheter penetrates the hydraulic chamber. II and the rotating chamber are fixedly connected to one end of the oil filling port I, so that the hydraulic oil enters the interior of the hydraulic chamber I through the conduit and the oil filling port I. At this time, the liquid pressure inside the hydraulic chamber I increases, thereby pushing the limit plate. It protrudes from the inside of the hydraulic chamber I, because the limit plate cooperates with the lock groove II when the lock groove I is in the locked state, so that the limit plate will be inserted into the lock groove II after being extended at this time, so as to lock one side of the lock plate. When the device has hydraulic failure, the side of the locking plate cannot be reset because it is held by the limit plate, so as to ensure that the attachments connected to the device will not fall off at this time to avoid The occurrence of safety accidents is prevented, and the safety performance of the device is improved.
Description
technical field [0001] The invention relates to the technical field of engineering special vehicles, in particular to a hydraulic quick-change connector for excavators. Background technique [0002] Excavators are often seen on construction sites. It is an indispensable construction machine in today's engineering construction. It can quickly excavate and transfer earthwork, thereby saving a lot of labor. With the development of science and technology, the current excavator One end of the forearm can not only be connected to the bucket, but also connected to various construction machinery, such as demolition machines, road rammers, etc., which has the effect of being a multi-purpose machine and greatly improves its practicability. In order to enable the excavator to quickly To replace these attachments, a quick-change connector will be installed at one end of the forearm of the excavator, so that the attachments can be quickly replaced during construction. The existing quick-...
