Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] refer to figure 1 , figure 2 , the present embodiment comprises oil cylinder 1, mechanical lock 2, automatic hook device 12 and hydraulic system, and mechanical lock 2 is installed on the outer wall of cylinder barrel of oil cylinder 1 in pairs, and automatic hook device 12 is fixed on the piston rod end of oil cylinder 1, and mechanical lock 2. It has three working states: full open state, locked state, and reset state. The automatic hook 12 can enter the interior of the mechanical lock 2 in the fully open state of the mechanical lock 2, push the mechanical lock 2 upwards to the reset state through the collision, and The automatic hook 12 is automatically locked under the action of gravity; the mechanical lock 2 is provided with an unlocking rope 15, and the unlocking rope 15 is tightened to unlock the mechanical lock 2; the...

Abstract

The invention discloses an automatic hydraulic unhooking device. The automatic hydraulic unhooking device comprises an oil cylinder, an automatic hooking device and a hydraulic system for controlling the pressure of a rod cavity of the oil cylinder, wherein the automatic hooking device is fixed at the end part of a piston rod of the oil cylinder; the automatic hydraulic unhooking device is also provided with mechanical locks, and the mechanical locks are mounted on an outer cylinder wall of the oil cylinder in pairs; an unlocking rope is arranged on the mechanical locks; an unhooking rope is mounted between the automatic hooking device and the mechanical locks; one end of the unhooking rope is connected with the automatic hooking device, and the other end of the unhooking rope is connected with the mechanical locks. According to the automatic hydraulic unhooking device disclosed by the invention, a hammer is lifted by the mechanical locks, and the hydraulic bearing of a high-speed oil cylinder is replaced by the rigid bearing of a mechanical-lock structure, so that the problem that when the heavy load of the high-speed oil cylinder is lifted, a piston rod slides off is solved; the working pressure in the high-speed oil cylinder is low, and the sealing, manufacturing and maintenance cost is low; the piston rod of the high-speed oil cylinder is unlocked by the mechanical locks through the traction of the unlocking rope, so that the automatic hydraulic unhooking device is simple and convenient to operate, high in reliability, and suitable for impact machinery to perform unhooking operation.

Description

technical field [0001] The invention belongs to the technical field of dynamic compaction construction equipment, and in particular relates to a hydraulic automatic decoupling device. Background technique [0002] Dynamic tamping machine is a kind of construction machinery used for impact compaction of materials or foundations, widely used in the construction of industrial and civil buildings, warehouses, yards, docks, airports, road and railway roadbeds, artificial islands, etc. . Due to the adsorption effect of the ramming pit on the rammer, the lifting force of the dynamic tamping machine to pull the rammer out of the ramming pit is significantly greater than the gravity of the rammer. When the oil cylinder is used as the working device for the dynamic tamping operation, the oil cylinder must meet the requirements of high-speed lowering. And stable load-bearing two functions. The hydraulic automatic decoupling device is a device used in the dynamic compaction machine to...
