U-shaped tube smoke guiding car uncovery gripper device

Abstract

The invention relates to the field of machinery equipment, and in particular relates to a U-shaped tube smoke guiding car uncovery gripper device. The device comprises an outer rod, an inner rod, a lifting lug, a hoop, a connecting rod, a first gripper, a second gripper, a gripper lifting oil cylinder, a gripper opening / closing oil cylinder and an opening / closing oil cylinder bracket, wherein the inner rod is connected with the lifting lug; two gripping plates are symmetrically arranged on the lifting lug and are hinged with the lifting lug; the action sequence of each gripper and a guide sleeve is as follows: the gripper falls off firstly, and then the guide sleeve falls off after a water sealing cover is clamped by the gripper, so that the whole actions of the grinder are clear and visible; a guiding rack and an auxiliary guide roller device are additionally arranged at each gripper, so that the gripper which acts up and down is prevented from being deflected; the oil cylinder for driving each gripper to move up and down and the oil cylinder for opening and closing each gripper are designed in a single-cavity and pressure-reducing manner, i.e., the speed deceleration and the pressure reduction are realized during the falling of the grippers and the closing of mechanical claws, so that the mechanical claws are prevented from being damaged by the oil cylinders in an ejection manner when the grippers are not accurately aligned or civil engineering errors are large.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a gripping device for uncovering a U-shaped pipe smoke guide vehicle. technical background [0002] At present, environmental protection is a major issue faced by human beings in modern life, and it is also one of the important contents of the scientific concept of development. Correspondingly, people's efforts to eliminate coking pollution and improve environmental quality are constantly being strengthened. Smoke guide trucks have been widely used as coke oven dedusting equipment. In the past, due to the deviation of furnace construction and the long-term thermal expansion and deformation of coke ovens, the arrangement of the water seals on the top of the furnace will have errors with the theoretical values ​​in the horizontal and vertical positions; Moreover, the action sequence of the traditional smoke guiding vehicle to grab the cover is to drop the sleeve to cover the w...

Smoke guide trucks have been widely used as coke oven dedusting equipment. In the past, due to the deviation of furnace construction and the long-term thermal expansion and deformation of coke ovens, the arrangement of the water seals on the top of the furnace will have errors with the theoretical values ​​in the horizontal and vertical positions; Moreover, the action sequence of the traditional smoke guiding vehicle to grab the cover is to drop the sleeve to cover the water seal first, and then drop the gripper to grab the cover. The operator cannot observe whether the gripper is grabbing the water seal. Phenomenon: the gripper and the water seal cover are in single line contact, the contact area is small, the grip cap is unstable, and the water seal cap often falls after being caught; the gripper has no guide, the gripper swings up and down, and the accuracy of the gripper movement is difficult to guarantee ; There is no single-chamber decompression for the gripper drive cylinder, the gripper descends and the gripper opens and closes quickly. Factors, the traditional smoke guiding vehicle grabbing device is difficult to ensure that four furnace covers are grabbed at the same time, which seriously affects the use effect of the smoke guiding vehicle
