Cantilever assembly equipment and hoisting method thereof

Abstract

The invention relates to the technical field of contact network hanging equipment, in particular to cantilever assembly equipment and a hoisting method thereof. The cantilever assembly equipment is characterized by comprising a left base, a movable tripod and a right base, wherein a horizontal slideway is arranged under the left base and the right base, which can slide on the horizontal slideway; the movable tripod is arranged between the left base and the right base and is in running fit with the horizontal slideway; support pieces for supporting and fixing a flat cantilever are arranged on the movable tripod and the right base; a support piece for supporting and fixing one end of an oblique cantilever is arranged on the left base; and a support piece for supporting and fixing a positioning tube is arranged on the right base. The cantilever assembly equipment has the advantages that the land occupation is small, operation areas are centralized, only narrow-range movement is required, working tools are used in a centralized manner, and parts are convenient and accurate in fastening.

Description

technical field [0001] The invention relates to the technical field of catenary suspension equipment, in particular to a wrist-arm assembly equipment and a hoisting method thereof. Background technique [0002] By the end of 2015, my country's high-speed railway operating mileage reached 19,000 kilometers, accounting for more than 60% of the world's total operating mileage of high-speed railways. China's high-speed railway is leading the development of high-speed railway in the world. Nowadays, China's high-speed railway has been integrated into people's daily life and has become an important part of my country's transportation field, bearing the lifeline of my country's economic development. With the rapid development of high-speed railways, the daily maintenance of high-speed railways is particularly important. The assembly of the wrist arm is an important part of the catenary construction, and it is also a necessary skill for the training and maintenance of the catenary...

AI Technical Summary

Problems solved by technology

[0004] At present, we mainly use the planar assembly method when assembling the wrist arm. This method requires extremely skilled assembly experience. For new recruits and general employees to assemble, many standards are difficult to meet the requirements.

After comparison and screening, the traditional wrist arm assembly method mainly has the following six disadvantages: first, it occupies a large area; second, the tools and appliances are scattered; third, it is inconvenient to fasten and there are deviations in the installation of parts; The fifth is potential danger; the sixth is wrist wear

[0006] One is that the upper and lower rod porcelain insulators are hoisted separately from the wrist arm body; this operation mode requires a lot of physical strength and requires the cooperation of ground support personnel and high-altitude operators

At the same time, there are many work items that need to be completed at high altitude, which is not conducive to the efficient completion of wrist-arm hoisting

[0007] The second is that the rod porcelain insulator is hoisted together with the wrist arm; in this mode of operation, it takes a long time for the ground support personnel to pull the rope and consume a lot of physical strength

The work items of high-altitude workers are relatively cumbersome, which is not conducive to the efficient completion of hoisting

[0008] Both of the above two hoisting modes require a high degree of cooperation between the high-altitude hoisting personnel and the ground support personnel. The physical requirements for the ground support personnel are relatively high, and the hoisting process is complicated and the efficiency is low.
