A rack type traction device

Abstract

The invention relates to a rack-type traction device. One end of a front end rack box is fixedly connected with a front end trolley, and the other end of the front end rack box is hinged to a tail end rack box. A transmission gear and a supporting wheel arranged coaxially are fixed below a support. Racks are arranged at the bottom of the front end rack box and the tail end rack box. A driving device drives the transmission gear to be in engagement transmission with the racks to achieve reciprocating motion of the front end rack box and the tail end rack box. The supporting wheel and the transmission gear rotate synchronously and bear load. The front end rack box pushes a rotating arm and the tail end rack box to move horizontally and rotate towards the upper front direction in the push-in direction of a coke pot. According to the rack-type traction device, the transmission method of gear rack engagement is adopted, the positioning precision and the operating stability are improved remarkably, and the service life of the device is prolonged significantly; in addition, the impact caused by start-stop and speed changing is reduced, and the utilization requirements for high strength and impact resistance are met; moreover, the tail end rack box has the function of moving horizontally and swinging, so that the space can be saved, and the requirement for application in a narrow site is better met.

Description

technical field [0001] The invention relates to a coke CDQ traverse traction device, in particular to a rack-type traction device with large traction weight and high positioning accuracy. Background technique [0002] As a major energy-saving and environmental protection technology, CDQ technology has good effects on improving coke quality indicators and reducing environmental pollution during coke quenching. In recent years, CDQ technology has been widely promoted in my country. [0003] The traction device plays a vital role in the production of the entire CDQ section. When the CDQ station is arranged parallel to the coke oven, a traction device is required to move the trolley carrying the red coke cans or empty coke cans horizontally between the hoist on the side of the CDQ station and the carrier car on the side of the coke oven. "Push in" or "push out", the coke pots and trolleys filled with red coke weigh more than 100 tons. [0004] The conventional traction device...

Problems solved by technology

Because the wire rope is prone to plastic deformation, its length and tightness will change after long-term work. If it is not adjusted or replaced in time, the positioning accuracy will decrease, so regular maintenance is required

In addition, due to the large impact when starting and stopping, the running stability of the traction device is poor, and the greater the traction weight, the greater the elastic deformation of the wire rope, and the more obvious the impact
