Description
Technical Field
The invention belongs to the technical field of hydraulic breaking, and particularly relates to a clamping and vertical lifting device for hydraulic breaking hammer test, which is a matched device of a hydraulic breaking hammer.
Background
The hydraulic breaking hammer has been developed for half a century, and has the advantages of high impact energy, strong adaptability, high reliability and efficiency, energy conservation, environmental protection and the like, so that the hydraulic breaking hammer is more and more valued by related professionals and engineering technicians at home and abroad. As an important breaking tool capable of being equipped on an excavator, the hydraulic breaking hammer replaces manual breaking and blasting to a certain extent, and has no function in improving working efficiency, construction safety, environmental protection and dust prevention, and few tools capable of replacing the hydraulic breaking hammer nowadays. At present, the method is widely applied to industries such as mining, metallurgy, road construction, municipal engineering, building, ship industry and the like. The requirements of the industrial pace of the society in China on engineering machinery are increasingly increased, and the hydraulic breaking hammer serving as the auxiliary equipment of the engineering machinery has wide prospect.
According to industry standard JB/T10844-2008, hydraulic breaking hammers are classified into hand-held hydraulic breaking hammers and airborne hydraulic breaking hammers. The hand-held hydraulic breaking hammer has the characteristics of high work efficiency, small volume, light weight, small back impact force, low noise, durability and the like, and does not need to be matched with an additional clamping and traveling device. However, the method has the defects of low power, low crushing energy and the like, and cannot be suitable for large-engineering-amount operation and special operation environments which cannot be accessed by some constructors. The machine-mounted hydraulic breaking hammer is mainly characterized in that the breaking hammer is arranged at the tail end of an arm frame of a hydraulic excavator or on other engineering machinery through a clamp. The mechanical arm of the hydraulic excavator moves, so that the breaking hammer has the movement characteristic of large range movement and rotation. The multi-angle multi-azimuth working posture can be well adapted to more complex working conditions, and the characteristics of high power and high impact energy are added, so that the multi-angle multi-azimuth working posture plays a role in various construction fields such as mining, tunnel engineering and the like. However, the on-board breaking hammer is mounted on a mobile construction machine such as an excavator, and therefore, this also results in that the on-board hydraulic breaking hammer is not suitable for a hydraulic breaking system performance test performed indoors or a working environment requiring fixation. At present, the technical field of hydraulic breaking hammers does not have hydraulic breaking machinery integrating two working modes, namely fixed operation mode and free operation mode, such as a full-rotary hydraulic breaker mentioned in Chinese practical patent publication No. CN201295622, wherein the hydraulic breaking hammers are connected at the tail ends of two arms through hinges, and a large arm is connected with a rotary table through a hinge. The rotary table can horizontally rotate at a low speed of 360 degrees. The full-rotary hydraulic crusher belongs to an onboard crushing hammer, and can realize large-scale rotary work, but does not relate to a fixed vertical crushing operation mode. Another rock breaking device is mentioned in Chinese patent (publication No. CN 201714389U), which also belongs to the technical field of the airborne hydraulic breaking hammer, and is provided with a rotary table, a rock breaking arm and a breaking hammer. Nor does it relate to vertical crushing techniques that can be fixed. The vertical clamping and vertical lifting technology of the breaking hammer for testing has a quite wide application prospect by combining the existing hydraulic breaking technology and the requirements of fixed working environments.
