Abstract
The utility model relates to a magnetic drag chain, in order to overcome the defect that a device is easily collided and damaged by transverse swing of the existing drag chain when the drag chain moves up and down. The magnetic drag chain comprises chain plates (1), support plates (2) and pin shafts (3), wherein the chain plates (1) are sequentially connected into a chain shape by the pin shafts (3); the two chain-shaped chain plates are connected transversely by the support plates (2); the support plates are provided with wiring grooves; the support plates (2) are magnetic plates and are adsorbed on a support surface (5) of the device; and the included angle between the support surface (5) and the plane is more than 0 degree. The magnetic drag chain has the beneficial effects that the magnetic drag chain solves the problem that the device is damaged due to collision of the drag chain and the device when the drag chain swings during upward and downward movement, and the safety performance of the device is improved.
Description
Affiliated technical field
The utility model relates to a kind of drag chain, especially relates to a kind of magnetic drag chain.
Background technique
Drag chain is widely used in fields such as numerical control machine tool, electronic equipment, warehouse automation, has protected equipment cable, oil pipe, tracheae, also makes equipment integral more attractive in appearance, has easy for installation, reliable, the easy-to-dismount characteristics of use.Drag chain commonly used has two kinds of steel drag chain and plastics drag chains.
Drag chain also is widely used on oil drilling and extracting equipment, mixed and disorderly actuating cable line, oil pipe, tracheae fitly is arranged in the wiring groove of drag chain to be protected, and prevents the damage of pipelines such as elastic cable paper, oil pipe, tracheae.When equipment moved, drag chain can be rolled around chain rivet, had good ductility and sheathed, drag chain bending motion that the adaptation radius is different and frequent moving, and equipment can drag elastic cable paper, oil pipe, tracheae length apart from moving.
Usually drag chain is a horizontal positioned, moves and rolls with equipment, and stable action does not have the phenomenon of colliding with.When equipment moves up and down, make a trip etc. as drilling and repairing machine, when drag chain will vertically be placed, because action of gravity, can produce the substantially horizontal swing during drag chain motion, if the swing of drag chain is not limited, equipment can be collided with, heavy then with device damage, and have potential safety hazard.
The model utility content
When moving up and down in order to overcome existing drag chain, the deficiency that the drag chain teeter collides with equipment, damage easily, the utility model provides a kind of magnetic drag chain.This magnetic drag chain can effectively prevent the drag chain horizontal hunting when moving up and down.
The technological scheme that its technical problem that solves the utility model adopts is: the magnetic drag chain comprises carrier bar, dunnage, bearing pin, bearing pin connects to form chain successively with carrier bar, dunnage laterally connects two chain carrier bars, wiring groove is arranged on the dunnage, dunnage is a magnetic sheet, and dunnage is adsorbed on the supporting surface of equipment; Angle between supporting surface and the horizontal plane＞0 °
The beneficial effects of the utility model are, solve drag chain and produce swing in moving up and down, and drag chain and the equipment damage equipment that bumps has improved device '.
Description of drawings
Fig. 1 is a magnetic drag chain structure schematic representation of the present utility model.
Fig. 2 is the utility model working state figure.
Among the figure: 1. carrier bar, 2. dunnage, 3. bearing pin, 4. drag chain, 5. supporting surface.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The utility model magnetic drag chain; comprise carrier bar 1, dunnage 2, bearing pin 3; bearing pin 3 connects to form chain successively with carrier bar 1; dunnage 2 laterally connects two chain carrier bars; on the dunnage 2 wiring groove is arranged; elastic cable paper on the equipment, oil pipe, tracheae fitly are arranged in the drag chain wiring groove and are protected, and prevent to damage.When equipment moved, drag chain 4 can be rolled around chain rivet, had good ductility and sheathed.Dunnage 2 is a magnetic sheet, and dunnage 2 is adsorbed on the supporting surface 5 of equipment.Angle between supporting surface 5 and the horizontal plane＞0 °.
Supporting surface 5 is generally the component in the equipment, if can not provide corresponding supporting surface on the existing equipment, also can add a supporting surface 5.
The utility model magnetic drag chain has increased magnetic in dunnage 2, drag chain 4 is in vertical motion, rely on magnetic can be adsorbed on the supporting surface 5, drag chain 4 the horizontal hunting phenomenon can not occur, increased the stability of drag chain 4, can not produce and the equipment collision, improve job security, thereby solved the problem that drag chain occurs in vertical using process.
The utility model magnetic drag chain can be applied in the steel drag chain, also can be applied in the plastics drag chain.
The application of the art of this patent is not limited only to the oil equipment, also is applicable to other field.It should be noted that the foregoing description is example and unrestricted the present invention, those skilled in the art can design a lot of alternate embodiments and not break away from the scope of claim.
Claims (2)
1. a magnetic drag chain comprises carrier bar, dunnage, bearing pin, and bearing pin connects to form chain successively with carrier bar, dunnage laterally connects two chain carrier bars, wiring groove is arranged on the dunnage, it is characterized in that: dunnage (2) is magnetic sheet, and dunnage (2) is adsorbed on the supporting surface (5) of equipment.
2. magnetic drag chain according to claim 1 is characterized in that: angle＞0 between described supporting surface (5) and the horizontal plane °.
