Remote numerical control multipurpose uphill and downhill trolley

Abstract

The invention relates to a remote numerical control multipurpose uphill and downhill trolley for an automated conveying production line, which comprises a trolley capable of running on a flat road or an uphill ramp and a downhill ramp and five trolley lines additionally arranged on one side of a track. An electric cabinet frequency converter, a hanging fixture and the like are arranged on the trolley and are communicated with a master control cabinet through the trolley lines and a cable. In the remote numerical control multipurpose uphill and downhill trolley, the technology of numerical control and half-duplex communication is adopted particularly, so that the trolley can be commanded manually or automatically by PLC programs to complete complex actions such as quick and slow advance and retreat, lifting, release, clamping and the like within the range of 3,000 meters; the technology of automatic frequency control of motor speed is also adopted, so that the trolley can move on the uphill ramp and the downhill ramp or a curve road at a low speed and move on the flat road at a high speed; and the technology of dual braking and electric speed limit is adopted to ensure the safety of the trolley on the uphill ramp and the downhill ramp. The remote numerical control multipurpose uphill and downhill trolley provides novel three-dimensional space automated material conveying equipment with omnipotency, high efficiency and low cost for manufacturers such as automobiles, engines, machinofacture and the like.

Description

(1) Technical field: [0001] The invention belongs to the technical field of mechatronics equipment manufacturing, in particular to a remote numerical control multi-purpose uphill and downhill trolley. The CNC trolley is suitable for the automatic material conveying production lines of automobile, engine, machinery manufacturing and other manufacturers operating on horizontal tracks or up and down slope tracks. (two) background technology: [0002] In China, the current automated production lines used to transport materials with different horizontal or vertical heights all use suspended accumulation chain systems. Its structure mainly adopts two parallel angle steels with openings facing inwards, with a non-stop rotating chain sandwiched between them. Two angle steels are used as rails to bear the weight of the suspended trolley and materials, and the trolley is in contact with the angle steels by four small iron wheels and hangs and rolls on them. A paw is installed on the...

AI Technical Summary

Problems solved by technology

Its main problems are: 1: single function

But because this kind of trolley still adopts the traditional old-fashioned electrical control method in which one line controls one action, this kind of trolley also has the following problems: 1: The space on the side of the track is limited by the number of sliding contact lines. , the trolley can do very few actions, cannot be attached with hoists or fixtures, and can only work at fixed points, the working range of the trolley is very narrow, and the performance is poor; Less than 20M per minute, the production rhythm is low, resulting in a large number of trolleys, and high installation and maintenance costs; 3: When the trolleys are going downhill, they are decelerated by the friction plate of the speed-limiting centrifuge, and there is still noise pollution
