Abstract

PURPOSE:To reduce noise generated upon demolishing of steel pipes which are piled up on a skid, by attracting the steel pipes onto magnets provided with an opening and closing mechanism, and as well by opening and closing these magnets to demolish the pile of the steel pipes. CONSTITUTION:Before loading of steel pipes a pair of cylinders 40a, 40b are raised so that a pair of movable electromagnets 50a, 50b are set in an inverted V-like arrangement. When a plurality of steel pipes 10 are loaded on a stationary magnet 60, the electromagnets 50, 60 attracts thereonto the steel pipes 10, and as well the cylinders 40a, 40b are lowered to lay the movable magnets 50a, 50b until they take their substantially horizontal postures. Thereafter the electromagnets 50, 60 are deenergized to allow the steel pipes 10 to roll on an inclined skid, and a steel pipe transfer noise preventing device 70 exerts brake force to the steel pipes 10 which are therefore conveyed at a low speed with low noise.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a device that uses a screw magnet to reduce the roughness that occurs when a plurality of steel pipes are loaded onto a skid using a crane or the like and broken into stages.

[Background of the invention]

Generally, in the steel/tl''A construction department at a steelworks, etc., a sloped rail is used to transport the manufactured FC steel, and the steel is allowed to move freely on the skin rail. ＃I'm letting you do it.

In addition, in the conventional 2-in tank, due to the manufacturing process, it is necessary to load g = books on atτ skids using a crane or the like, and then transport them to the next process for processing.

At this time, the 11111m'# loaded on the skid became two or three tiers and 'J? 9. -1 is generated when the steel U in the upper tier (second tier, third tier) falls onto the skit. This noise is louder than the steel d and multiple fcs. Also, is there a flaw in the steel d to prevent it from falling? It can also cause deformation.

A conventional example will be explained with reference to FIG. In Fig. 1(a), the steel-#lO of the red tape that was loaded onto the skid 20 by the crane 5 at 29 was in two and three tiers on the skid before the bundle of wires 6 was folded. ing. When the bundle of wire 6 is folded up, the steel and dlO are in the upper row A as shown in the figure, skid 20.
This can cause the metal to fall onto the ground, causing noise as mentioned above and causing flaws and deformation of the steel clamp. Skid 20f excited steel d
is carried out onto the V roller 22 by the kicker 21 at the end of the skid, and then transferred to the next process.

In this way, with the rice cultivation method, there are problems such as a decline in work efficiency and a decline in the quality of steel due to the deterioration of crop conditions, and countermeasures have been taken.

[Embodiments of the invention]

Next, a specific embodiment of the present invention will be explained with reference to FIGS. 2 and 3.

Figure 2 shows the overall structure.

(a) is a plan view of the present device. The illustration shows only the first power, but depending on the length of the pipe = iv! The number needs to be in the third or fifth power. (b) is a side view in which the steel g is loaded on a fixed electromagnet 60. 50a and 50b are movable electromagnets, and this one magnet is operated by the driving device 40a and 40b. A steel pipe transfer noise prevention device 70, which we have already proposed, is placed at one lateral transfer location. That is,
Multi-ridged electromagnets are arranged on the skid to apply braking to the steel (a) and control the conveyance speed of the steel (g) to reduce collision noise.

Next, details of the movable range magnet portion of this device will be explained with reference to FIG. The movable range magnets 50a, 50b are connected to the frame 81 by pins 82a, 82b.

83a and 83b are support stands for flexible magnets, and are made of steel pipes.
The cylinders 4Qa and 40b are shaped to have protrusions and receive the weight t' on the side surface of the frame 81 so that the cylinders 4Qa and 40b are not loaded.

The exciter magnet and support stand are either welded or bolted. The support stand and the cylinder are connected by pins 84a and 84b. 85a.

Reference numeral 85b designates the arrangement G for raising the movable magnet 1, and 86a and 86b designate the arrangement J for lowering it.

Next, how does the invention work? ! -Explain.

Steel pipe 'f1: 4Jf Before the cylinders 40a and 4
Supply a hydraulic or pneumatic drive source to 0b through the arrangement of 85a and 85b, move the cylinder to its upper limit position, set the movable range magnet in the V-shaped position as shown in Figure 2, and complete the preparation. .

In FIG. 4(a), when AMlO is loaded on a constant magnet 60, the electromagnet is excited, and the 0]' dynamic magnet 50a,
After adsorbing steel d with 50b, cylinders 40a and 40
b is supplied through the arrangement 1 of mmgk86a, 86b, and the cylinder is operated until it is flush with the top surface of the steel/d transfer noise prevention device 70.

As shown in FIG. 4(b), when the cylinders 40a and 40b are on the same plane, the fixed acid magnet 60 and the movable turtle stones 50a and 50b are de-energized, and the steel g is tilted to the skid. After that, the steel g is transferred at low speed by applying power to the steel g using the noise prevention device 70 and conveyed at low speed.

Also, in order to cause the steel pipe to roll and break down, if you not only turn off the excitation but also perform reverse excitation to cancel out the residual magnetism of the electromagnet, the steel a will no longer stagnate on the electromagnet.

〔Effect of the invention〕

This @Suzuki is currently capable of reducing the noise generated in the so-called sakazuki line of steel pipes and improving the quality of the steel pipes, as well as improving the quality of the steel pipes.
