Description
Technical field
The utility model relates to drag chains to support field, and in particular to a kind of drag chain support device.
Background technique
Drag chain is suitable for use in the occasion of reciprocating motion, can play to built-in cable, oil pipe, tracheae, water pipe etc.
Traction and protective effect.Drag chain has been widely used in numerically-controlled machine tool, electronic equipment, stone machining equipment, glass machinery, door and window machine
Tool, injection molding machine, manipulator, handling equipment, Automatic Warehouse etc..In the general companion of the movement of laser cutting process middle cross beam
With the movement of drag chain, drag chain during the motion, since drag chain stroke is too long, is easy to cause drag chain to collapse, in the prior art
Drag chain is generally supported using supporting rod, but since the position of drag chain supporting point during the motion will not change, but
It is that drag chain center of gravity can generate displacement, when drag chain center of gravity and excessive supporting point spacing, the drag chain of supporting point two sides just will appear not
Balance, the drag chain close to center of gravity side can be to tenesmus, and there will be the trend to raise up, drag chain is chronically at this imbalance for the other side
In the state of, the load of drag chain at supporting point can be aggravated, drag chain at supporting point is resulted even in and is broken.
Utility model content
The utility model provides a kind of drag chain support device, solves prior art drag chain center of gravity and supporting point spacing is excessive
When, drag chain imbalance aggravate supporting point at drag chain load the technical issues of.
The scheme that the utility model solves above-mentioned technical problem is as follows: a kind of drag chain support device, including bracket, main support
Part and secondary supporting element, the bracket includes bottom plate and two end plates, and two end plates are symmetrically installed and the bottom plate both ends；Institute
Stating main supporting element includes main support roller and shaft, and the shaft is installed between two end plates, the main support roller
It is rotatably installed in the shaft, is used to support drag chain；Secondary supporting element is rotatably set to the two of the main supporting element
Side is used to support the drag chain of the main support roller two sides.
In the present invention, the region that main support roller is contacted with drag chain is supporting point, passes through secondary supports support
The drag chain of main support roller two sides, is equivalent to and increases the contact area of support roller and drag chain, can effectively reduce supporting point
Secondary supporting element is rotatably set to the two sides of main supporting element by the drag chain load at place, and drag chain can be allowed to send out in supporting point two sides
When raw inclination, secondary supporting element still can effectively form drag chain and support.
The above description is merely an outline of the technical solution of the present invention, in order to better understand the skill of the utility model
Art means, and can be implemented in accordance with the contents of the specification, below on the preferred embodiment of the present invention and the accompanying drawings in detail
It describes in detail bright as after.Specific embodiment of the present utility model is shown in detail by following embodiment and its attached drawing.
Detailed description of the invention
Attached drawing described herein is used to provide a further understanding of the present invention, and is constituted part of this application,
The exemplary embodiment of the utility model and the description thereof are used to explain the utility model, does not constitute to the improper of the utility model
It limits.In the accompanying drawings:
Fig. 1 is the planar structure schematic diagram of the utility model embodiment；
Fig. 2 is the utility model embodiment neutral body structural schematic diagram；
Fig. 3 is the cooperation schematic diagram of the utility model embodiment protrusions and groove.
Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.It is more specifically described by way of example in the following passage referring to attached drawing
The utility model.According to following explanation and claims, will be become apparent from feature the advantages of the utility model.It should be noted
It is that attached drawing is all made of very simplified form and using non-accurate ratio, only to facilitate, lucidly aid in illustrating this reality
With the purpose of new embodiment.
As shown in Figure 1, the utility model provides a kind of drag chain support device, a kind of drag chain support device, including bracket
1, main supporting element 2 and secondary supporting element 3.
The bracket 1 includes bottom plate 11 and two end plates 12, and two end plates 12 are symmetrically arranged on the bottom plate both ends.
The main supporting element 2 includes main support roller 21 and shaft 22, and the shaft 22 is installed on two end plates 12
Between, the main support roller 21 is rotatably installed in the shaft 22, is used to support drag chain.
The pair supporting element 3 is rotatably set to the two sides of the main supporting element 1, is used to support the main support roller
The drag chain of 21 two sides.
Specifically, the pair supporting element 3 includes two connecting rods 31, and the secondary support rollers 33 of two auxiliary spindles 32 and two, two
A connecting rod 31 is symmetrically disposed on the both ends of the shaft 22, and middle part is rotatablely connected in the shaft 22, and two
The auxiliary spindle 32 is installed between two connecting rods 31, and is located at the two sides of the shaft 22, the pair back-up roller
Cylinder 33 is rotatably installed on the auxiliary spindle 32 correspondingly.
Preferably, what the connecting rod 31 can be self-locking is connected in the shaft 22.
As the preferred embodiment of this implementation, through-hole 31a is equipped in the middle part of the connecting rod 31, the side wall of through-hole 31a is equal
It is even to be equipped with multiple raised 311, described raised 311 are corresponded in the shaft 22 and forms fluted 22a, and the shaft 22 is arranged in institute
It states on through-hole 31a.
By protrusion and groove cooperation, by connecting rod can be self-locking be connected in the shaft, ensure that secondary supporting element exists
, can be more stable when supporting drag chain, it will not become not reliable because of the shaking in drag chain motion process.
Wherein, the barrel dliameter of the secondary support roller 33 is less than the barrel dliameter of the main support roller 21.
The barrel dliameter of pair support roller 33 is less than the barrel dliameter of the main support roller 21, it is ensured that when supporting point is close to drag chain
When center of gravity, the drag chain of center of gravity two sides can gently drop, and preferably protect drag chain, extend the service life of drag chain.
In the present invention, the region that main support roller is contacted with drag chain is supporting point, passes through secondary supports support
The drag chain of main support roller two sides, is equivalent to and increases the contact area of support roller and drag chain, can effectively reduce supporting point
Secondary supporting element is rotatably set to the two sides of main supporting element by the drag chain load at place, and drag chain can be allowed to send out in supporting point two sides
When raw inclination, secondary supporting element still can effectively form drag chain and support.
The above, the only preferred embodiment of the utility model not make in any form the utility model
Limitation；The those of ordinary skill of all industry can be shown in by specification attached drawing and described above and swimmingly to implement this practical
