Shearing jaw-detachable hydraulic bolt cutter

Abstract

The invention discloses a shearing jaw-detachable hydraulic bolt cutter. The shearing jaw-detachable hydraulic bolt cutter comprises a base; a disc is mounted in middle of the upper end of the base; multiple sets of engagement teeth are uniformly arranged on the inner side wall of the disc; a fixed plate is fixedly mounted at the upper end of the disc; a first hydraulic cylinder is fixedly mountedin middle of the upper end of the fixed plate; a separation plate is fixedly mounted at an extension end of the first hydraulic cylinder; a support frame is mounted on the separation plate; a secondhydraulic cylinder is connected into the support frame; a connecting piece is arranged under the second hydraulic cylinder; a detachable module is arranged under the connecting piece; a shearing jaw is arranged under the detachable module; and a cutter groove module, connected with the separation plate, is arranged under the shearing jaw. The shearing jaw-detachable hydraulic bolt cutter is convenient to shear circuits in air, meanwhile, is convenient to change various angles to achieve shearing, can replace shearing jaws through disassembly, is convenient to operate, reduces the coat, can shear more circuits within the same time, accelerates the shearing speed, and is wide in the application range and higher in practicability.

Description

Technical field [0001] The invention relates to the technical field of rescue tools, in particular to a hydraulic bolt cutter with a detachable cutting jaw. Background technique [0002] The hydraulic cutter is one of the hydraulic cutters used in emergency rescue. The hydraulic cutter is made of aerospace high-strength lightweight alloy, which is light in weight, strong in shearing, and takes a short time to open and close, which accelerates the rescue process. , Hydraulic cutters can be used for road, railway and other traffic accident rescue, earthquake disaster and building collapse rescue, air disaster and shipwreck rescue, cut off vehicle components, metal structures, pipelines, special-shaped steel and steel blades use high-quality heat-treated tool steel. The surface is anodized and has good abrasion resistance. The movable parts are equipped with protective covers, shearing and splashing prevention and automatic reset manual steering valve, which provides safety guarante...

AI Technical Summary

Problems solved by technology

[0004] 1. The current hydraulic cutter basically requires manpower to operate. When cutting steel bars with relatively thick diameters, it is more laborious to cut manually, which also affects the cutting speed.

[0005] 2. The common cutters on the market are too bulky, and it is inconvenient to operate manually when the cutting height is high. At the same time, the hydraulic cutters cannot be adjusted at multiple angles, and it is not convenient to cut at various angles.

[0006] 3. The blades on the current hydraulic cutters are easily damaged. Once damaged, the entire product will be scrapped. Even if it is repaired, the price is almost the same as the entire product. At the same time, some blades are not easy to replace, or it is inconvenient to replace.
