The automatic double anchor cable blanking bending all-in-one machine

Abstract

The invention discloses an automatic double anchor cable blanking bending all-in-one machine, which comprises a horizontal pay-off disc, a traction device, a cutting device, a discharging device and a bending device. The horizontal pay-off disc is a horizontal pay-off disc with double structure arranged horizontally on the axis. The traction device and the cutting device are mounted on the same frame. The cutting device is located at the rear end of the traction device and is arranged close to the discharging device. The traction device is driven by the hydraulic motor, the cutting of the anchor cable is completed by the ion cutting gun, the opening of the sealing plate of the discharging device is driven by the discharging cylinder, and the length of the anchor cable to be discharged is defined by the stroke controller. The cable after discharging is bent by the bending device. In that invention, the two discs of anchor cables can be simultaneously carried out the discharging operation, the production efficiency is high, the traction, the cutting and the discharge of the anchor cable can be completed automatically, the single person can operate, the labor intensity is low, the structure is small, the device occupying space is small, the safety is high, the operation and maintenance is simple, and the device can be used for discharging and bending the anchor cable.

Description

technical field [0001] The invention belongs to the field of anchor cable blanking equipment for support, in particular to an integrated machine for automatic blanking and bending of double anchor cables. Background technique [0002] Anchor cables, commonly known as steel strands, are twisted from multiple high-strength steel wires. They are mostly used in engineering parts that have been deformed or have strict deformation requirements in civil engineering or coal mine underground operations. With the advantages of large length, flexibility, high bearing capacity, convenient transportation and early load bearing, it has become the main method of coal mine roadway support. Before the anchor cable is installed, it is necessary to ensure that each steel strand is straight, not twisted or crossed, and arranged evenly, and the rust and oil are removed. The anchor cables with dead bends, mechanical damage and rust pits must be removed. An anchor cable tensioning machine is requ...

AI Technical Summary

Problems solved by technology

Due to the extremely high hardness of the steel strand (1860MPa), not only the consumption of the saw blade is very large, but also the cutting speed is slow and the production efficiency is low; at the same time, a large amount of dust and toxic gas generated by cutting will damage the health of workers and seriously pollute the environment

In addition, the equipment required by the existing technology can only place a coil of steel strands, and saw and cut one anchor cable at a time, so the production efficiency is low

China's invention patent application "Automatic Unloading Method and Equipment for Steel Strand Anchor Cable" (Application No.: 201210526400.7) provides a method of producing steel strands using double-disc racks, eddy current local heating of steel strands, and hydraulic shearing The automatic feeding method and equipment for wire and anchor cables. This technical scheme can improve the production efficiency of anchor cable blanking and avoid dust pollution. However, there are still problems in this technical scheme in practice: due to the rotation of the two steel strand coils The axis is arranged horizontally up and down, not only it is inconvenient to install the anchor cable (steel strand), but also the axial displacement (horizontal displacement) along the steel strand coil frame changes greatly during the process of setting out the anchor cable; it needs to be used when unloading The eddy current heater locally heats the anchor cable; cutting the anchor cable with a hydraulic shear is easy to deform or scatter the head of the anchor cable, which makes it impossible to cooperate with the supporting plate, anchorage and tension jack during installation

China's invention patent application "Explosion-proof mining double-cable automatic cutting machine" (application number 201310606922.2) provides a double-cable automatic cutting device using high-pressure water jets as a cutting device, but its cutting efficiency is low, and No cable bending function
