A lifting limit device of double protective pipes for construction lifting machinery

Abstract

The invention provides a double-protection pipe hoisting limit device for construction hoisting machinery, relates to the technical field of pipe hoisting, and includes a main assembly and an auxiliary assembly; a synchronous gear is installed inside the main assembly, and the main The mounting parts are respectively connected with the auxiliary mounting parts and the movable auxiliary frame through sliding rods; the peripheral of the auxiliary mounting parts is circular, and the peripheral of the auxiliary mounting parts is surrounded by six hoisting holes, and the flexible buffer block is connected with the side baffles The auxiliary parts are connected; the gear rod is connected to the inside of the main part, and the auxiliary part is connected to the movable auxiliary frame through the gear rod; the center part of the movable auxiliary frame is hollow, and the external part of the movable auxiliary frame is connected to the manual bolt; In the present invention, after the pipe fittings are respectively placed in the storage holes inside the main fitting through the loading and unloading openings, the left and right ends of the pipe fittings are respectively inserted into the limit inner holes set by the auxiliary fittings at both ends, and the two ends of the pipe fittings are connected by the auxiliary fittings The end is limited to prevent the pipe fittings from falling out of the loading and unloading port during hoisting, causing damage to the ground construction personnel, and making the pipe fittings loading and unloading more convenient.

Description

technical field [0001] The invention belongs to the technical field of pipe hoisting, and more specifically relates to a double-protection pipe hoisting limit device of a construction hoisting machine. Background technique [0002] Hoisting machinery is a mechanical device that uses the principle of leverage to lift objects from the bottom to high places through hydraulic, motor and other driving methods to change their positions. It is as large as the tower crane for lifting containers at the wharf, and as small as the manpower required for the production and transshipment of goods in the workshop. Cranes and hoisting machinery have brought a lot of convenience to production work and improved work efficiency. Tubular building materials are usually hoisted and transported by hoisting machinery. [0003] The limit device for pipe hoisting can refer to Patent No. CN211545738U, which mainly includes a sliding base, a mobile base is installed on the inside of the sliding base, a...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a double-protection pipe lifting limit device for construction hoisting machinery, so as to solve the problem that when the existing similar pipe lifting limit devices are in use, steel wire ropes are usually used to control the pipe building materials. Simple bundling, and then hoisting and transportation of the bundled pipe building materials, the safety risk is relatively large, and the pipe building materials are easy to fall during the hoisting process, causing safety hazards
