Straight line distributed steel fiber concrete hydraulic manhole cover forming machine and use method thereof

Abstract

Disclosed is a straight line distributed steel fiber concrete hydraulic manhole cover forming machine. The straight line distributed steel fiber concrete hydraulic manhole cover forming machine comprises straight line conveying machine frames, a vertical machine frame, a reciprocating propelling device, a manhole cover forming jolt ramming device, a vibration charging device, a model frame lifting and dropping compressing device, a manhole cover support plate, a manhole cover forming model frame and an electronic control device, wherein the straight line conveying machine frames are distributed on two sides of the vertical machine frame, the reciprocating propelling device is arranged at a model entering end, the manhole cover forming jolt ramming device can perform high-frequency vibrations on the manhole cover forming model frame placed above the manhole cover forming jolt ramming device so as to enable the concrete in the manhole cover forming model frame to be enriched and uniform-distributed, the model frame lifting and dropping compressing device enables the manhole cover forming model frame to simultaneously lift up and drop down therewith, the vibration charging device is installed on the vertical machine frame, a discharge port of the vibration charging device is aligned with an upper end opening of the manhole cover forming model frame, and the electronic control device controls movements of the reciprocating propelling device, the manhole cover forming jolt ramming device, the vibration charging device and the model frame lifting and dropping compressing device. The straight line distributed steel fiber concrete hydraulic manhole cover forming machine can achieve mechanization of original manhole covers production with high labor intensities, low production efficiencies and unstable qualities.

Description

Technical field: [0001] The invention relates to a device for making a well cover and a manufacturing method thereof. Background technique: [0002] At present, most of the production of manhole covers is made by artificial modeling method. The casting mold is placed on the level ground of the production site, and the concrete material is manually added for manual flattening, compaction, and surface bonding, and then natural curing. Get the corresponding manhole cover from the mold. [0003] Although a small number of enterprises have begun to use machinery to make manhole covers, the machines used are simple vibration forming machines. The specific production method is to install the manhole cover concrete casting mold on the workbench of the vibration forming machine, and the operator manually adds concrete materials. Through the high-frequency vibration of the vibrating molding machine, the concrete is filled into the mold cavity, and the upper surface is basically flat,...

Problems solved by technology

[0003] Although a small number of enterprises have begun to use machinery to make manhole covers, the machines used are simple vibration forming machines. The specific production method is to install the manhole cover concrete casting mold on the workbench of the vibration forming machine, and the operator manually adds concrete materials. Through the high-frequency vibration of the vibrating molding machine, the concrete is filled into the mold cavity, and the upper surface is basically flat, and then the operator uses a manual surface tool to smooth the surface, and then the mold is solidified, the mold is demoulded and the cover is removed, and finally the mold is removed. The manhole cover is solidified and maintained. Although the labor intensity has been reduced and the production efficiency has been improved by this production method, manual feeding is still required, and manual handling is required after forming. The labor intensity is still too high, and the production efficiency of the cover is not high. , the cap production per hour is 5-8 pieces, the product quality is not easy to control, and the qualified rate is about 85%.
