A tensioning device and tensioning method for chain installation and adjustment

Abstract

The invention provides a tension device for installation and adjustment of a chain, and a tension method thereof. The device comprises a rack and a sliding part located below the rack and used for arranging the rack. Baffles are fixed to both sides of the sliding part in parallel, and a rocker is hinged between the two baffles through a hinge shaft; the bottom of the rocker is hinged with a knockout pawl located below the hinging position of the baffles and the rocker, and the knockout pawl is fit to the rack; the bottom of a sliding block is fixedly provided with a first hook head, and the bottom of the rack is fixedly provided with a second hook head; the device also comprises a limit device used for preventing the rack from exiting. In the invention, the knockout pawl is clamped between teeth on the rack, and both ends of the rack are fixed to the first hook head and the second hook head respectively; and the rocker is pushed, and the rack is driven to move by the knockout pawl along with the rocker so that the second hook head approaches to the first hook head to tension a chain, which can be completed by one person manually; the working efficiency is improved, and energy sources are saved; and the tension device is applied to different working occasions.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment, in particular to a tensioning device for chain installation and adjustment and a tensioning method thereof. Background technique [0002] During the installation and adjustment of large chains, it is often necessary to tighten the chains to a certain extent and then connect them with chain buckles. During the operation process, multiple personnel are required to work at the same time. Because there are no effective working tools, this operation process requires the cooperation of multiple people. Some personnel first use crowbars to tighten the chain and keep it in place, and other personnel install the chain buckle. It is time-consuming and labor-intensive, the adjustment degree is difficult to grasp, and the operation efficiency is low; in some operation situations, such as the operation environment without electricity and air source, electric and pneumatic tensioning tools cannot b...

During the operation process, multiple personnel are required to work at the same time. Because there are no effective working tools, this operation process requires the cooperation of multiple people. Some personnel first use crowbars to tighten the chain and keep it in place, and other personnel install the chain buckle. It is time-consuming and labor-intensive, the adjustment degree is difficult to grasp, and the operation efficiency is low; in some operation situations, such as the operation environment without electricity and air source, electric and pneumatic tensioning tools cannot be used, which brings difficulties to the chain installation; and special electric, Pneumatic tools are expensive, complex in structure, large in size, poor in versatility, and inconvenient to carry

During use, power cables or pneumatic pipelines need to be specially laid, and the preparation work is troublesome
