Description

Power-assisted net roller positioning transport vehicle

Technical Field

The utility model relates to the technical field of transportation equipment, in particular to transportation positioning equipment for a net roller, and specifically relates to a power-assisted net roller positioning transportation vehicle.

Background

In the production process of industrial filter screens (spiral screens or woven screens), blank screens produced in various processes are frequently rolled up on screen rolls or unreeled to equipment for processing in the production and processing processes of screening, heat setting, post-treatment and the like, and the blank screens are usually transported back and forth between machines of various equipment in a transition mode by the screen rolls in the process. The whole width of the industrial filter screen is usually between 5 and 10 meters, the rolling of the screen cloth is usually about 1 ton, and the influence of deflection and load of the screen roller is considered, so that the screen roller for unreeling or rolling has longer span and large dead weight, and other equipment is needed for auxiliary transportation in the transportation and positioning and installation processes. In the technical field of the industry, a crane is generally adopted to hoist the net roller beside an equipment machine in the existing net roller transportation and positioning installation process, and a worker manually and repeatedly adjusts the swinging position of the net roller in the air until the swinging position is matched with a chuck joint of net roller driving equipment. In the actual web roll transport and positioning operation, there are often several problems:

(1) The adjustable precision of the end of the net roller and the chuck joint of the driving device is only millimeter, and the net roller is transported and positioned in a suspension mode by adopting a crane, so that due to the large inertia of the net roller, a worker can hardly accurately position the end of the net roller and install the end of the net roller into the chuck joint of the equipment by controlling the crane or the net roller.

(2) The inertia of the net roller after crane lifting is large, the net roller is easy to damage equipment or a chuck of the equipment in the positioning or transportation process of the net roller, serious industrial injury is even caused, and great potential safety hazard exists.

(3) Traffic is often limited by the track, and web roll transport can only be performed in a limited area. But in the straddle carrier or non-drive area, web roll transport is limited. Of course, in this process, the industry also uses the trolley to carry out the parking of the net roller when no travelling crane is available, but the trolley only has the bearing function, and the net roller still cannot leave the travelling crane and cannot avoid the two problems.

Therefore, developing a transport device that can be combined with a net roller for lifting, transporting, accurately positioning and installing and is convenient to operate is a technical point to be solved.
