AI Technical Summary
When the workpiece is long, the chain pushers of the existing painting material transport trolley are prone to mutual interference, resulting in poor stability and energy waste. Furthermore, the workpiece cannot move forward when the chain fails.
It adopts a base with a travel wheel, and a power push block is set under the base. The power push block consists of a front push block and a rear push block. The front push block is fixed, and the rear push block is movably connected to the front push block through a hinge. The hinge is a spring hinge. The rear push block is attached to the back of the front push block under the action of gravity. The push block is designed with a notch to avoid interference from the chain push block.
It improves the stability of the material transport trolley used for painting, avoids interference and energy waste from the chain pusher, ensures the smooth movement of the workpiece, and prevents the material transport trolley from rolling over.

Description
TECHNICAL FIELD
[0001] The utility model belongs to work piece spraying device technical field, especially, relate to a paint spraying with material handling trolley. BACKGROUND
[0002] In the field of steel structure production, in order to avoid structural member is corroded, need to be sprayed on structural member paint or other anticorrosive coating. Because workpiece weight is big and length is longer, set up workpiece running track on paint spraying line, at least two with running wheel paint spraying with material handling trolleys are set up above workpiece running track, the existing paint spraying with material handling trolley includes the base with running wheel, support frame body is set up on the base, tool limiting frame is set up on support frame body, power push block is set up below the base, running wheel is located on workpiece running track, at least one set with chain transmission mechanism is set up in the position between two tracks, chain push block is set up on chain at interval one end distance, chain drives chain push block to advance, when chain push block advances to the rear of power push block of trolley, chain push block pushes power push block forward, drives paint spraying with material handling trolley to advance along workpiece running track, while workpiece is advancing, paint spraying is carried out through paint spraying device.
[0003] The above-mentioned paint spraying with material handling trolley has the following defects, first, because workpiece is long, when workpiece is located between two groups of chain wheels, because the running speed of two groups of chains is not same, different chain push blocks on chain are easy to interfere with each other, if the running speed of chain in front is slow, the running speed of chain in rear is fast, chain push block in rear is located behind power push block of paint spraying with material handling trolley in rear, and chain push block in front is located in front of power push block of paint spraying with material handling trolley in rear, chain push block on chain in rear pushes paint spraying with material handling trolley in rear forward, and chain push block on chain in front pushes paint spraying with material handling trolley in front backward, not only waste energy, but also cause workpiece to move relatively in paint spraying with material handling trolley, seriously, easy to cause material handling trolley to roll over, poor stability, second, when one group appears fault and leads to chain not moving, because immobile chain push block and power push block interfere with each other, workpiece cannot advance. SUMMARY
[0004] The utility model solves the technical problem that provides a paint spraying with material handling trolley, workpiece stability is good, even if chain appears fault and cannot rotate, workpiece can advance, save energy, and the effect of spraying is good.
[0005] To solve the above problems, the utility model discloses a paint spraying material handling trolley adopts technical scheme for: including the base with the wheel, be provided with the support frame body on the base, be provided with the tool limit frame on the support frame body, be provided with the power push block below the base, the power push block includes the front push block and the rear push block behind this front push block, the front push block is fixed with the base, the rear push block top is swing joint with the front push block, is provided with the push block gap in the front push block lower part close -to -the middle position.
[0006] Its additional technical features are:
[0007] The rear push block top is connected with the front push block through the hinge;
[0008] The hinge is a spring hinge.
[0009] Compared with the prior art, the paint spraying material handling trolley provided by the utility model has the following advantages: first, the base with the wheel is provided, the support frame body is provided on the base, the tool limit frame is provided on the support frame body, the power push block is provided below the base, the power push block includes the front push block and the rear push block behind this front push block, the front push block is fixed with the base, the rear push block top is swing joint with the front push block, is provided with the push block gap in the front push block lower part close -to -the middle position, the rear push block is attached to the rear of the front push block under the action of gravity, when the chain push block is located behind the rear push block, the chain push block pushes the rear push block and the front push block, drives the wheel to move forward along the workpiece track, when the paint spraying material handling trolley moving speed is greater than the chain push block moving speed, the chain push block is located in front of the power push block, the chain push block passes through the push block gap, the rear push block at the rear part of the chain push block is swung backward and upward because the rear push block top is swing joint with the front push block, the chain push block reaches the rear of the power push block without any resistance from the front of the power push block, after the chain push block reaches the rear of the power push block from the front of the power push block, the rear push block is attached to the rear of the front push block under the action of its own gravity, therefore, the interference between the power push block and the chain push block is avoided, energy is saved, the workpiece cannot move relative to the paint spraying material handling trolley, and the paint spraying material handling trolley cannot roll over, so the stability is good, that is, the chain push block can only provide forward thrust for the paint spraying material handling trolley, when the paint spraying material handling trolley moving speed is greater than the chain push block moving speed, the chain push block cannot become an obstacle for the paint spraying material handling trolley to move forward; second, the rear push block top is connected with the front push block through the hinge, preferably, the hinge is a spring hinge, and the rear push block is reset more quickly.
