Abstract
The utility model relates to a kind of returning devices of steel body trolley, fixation insulator including being fixed in trolley middle section and fixed setting, and the withdrawing device at trolley both ends is set, the withdrawing device includes the fixing buckle of fixed setting, and one end is connect with the fixing buckle, the Return spring that the other end is connect by the connecting plate that insulate with wiping thread end.The utility model is fixed trolley middle section by fixed insulator, deformation is set to be stretched or be shunk to both ends by temperature compensation means, and Return spring deforms, after temperature is restored, trolley both ends reset under the action of Return spring, after trolley is avoided because of variation of expanding with heat and contract with cold, longitudinal displacement occurs relative to workshop beam mechanism for trolley.
Description
Technical field
The utility model relates to the vehicling operation fields of industrial and mining enterprises, more particularly to driving steel body slide wire power supply dress
It sets, specially a kind of returning device of steel body trolley.
Background technique
The production line driving power supply unit of industrial enterprise mostly uses bareing steel body trolley, every inter-bank vehicle translation operation
Distance is up to 300 meters or so, and partial sector is in hot environment during production, and environment temperature is restored to during halt production.It is high
The variation of Low Temperature Difference causes the variation of the physical property of itself dilation of steel body trolley, in order to reduce due to temperature difference initiation
Usually temperature compensation means is arranged at the position apart from slip end 80-100m in deformation.But it is swollen because of workshop mechanism and trolley
The difference of swollen difference and trolley supports insulative bracket etc., while physical change occurs for trolley, although passing through
Temperature compensation means makes the deformation of trolley provide space, but longitudinal phase has occurred relative to original position for trolley
To displacement, it can not be restored to original position, trolley is made longitudinal leap occur.
Summary of the invention
In view of the shortcomings of the prior art, the utility model provides a kind of returning devices of steel body trolley, restore in temperature
When, so that the both ends of trolley reset, avoid longitudinal leap problem.
The utility model is achieved by the following technical solution, and provides a kind of returning device of steel body trolley, including
It is fixed in the fixation insulator in trolley middle section and fixed setting, and the withdrawing device at trolley both ends is set, described time
Drawing device includes that the fixing buckle of fixed setting and one end are connect with the fixing buckle, and the other end passes through insulation connecting plate and cunning
Touch the Return spring of thread end connection.
For this programme by the way that fixed insulator is arranged, when so that trolley expanding deformation, middle section is fixed, passes through
The temperature compensation means at both ends is stretched or is shunk, Return spring deformation tension or in compression, after temperature is restored, the both ends of slip
Under the action of Return spring power, it is restored to original position, cannot be restored to after stretching so as to avoid trolley original
Longitudinal leap problem caused by position.
As optimization, the fixed insulator is located at the middle position of trolley overall length.The setting of this prioritization scheme makes to slide
The both ends deformation for touching line is more balanced, and more conducively trolley both ends reset.
As optimization, the fixing buckle includes the fixing seat affixed with workshop, and the hook affixed with the fixing seat,
The hook is connect with Return spring.The fixation buckle structure of this prioritization scheme is simple, easy to connect with Return spring, be conducive into
Row replacement or maintenance.
As optimization, at least two connecting holes along trolley length direction arrangement are offered on the insulation connecting plate,
Insulation connecting plate is connect by passing through the bolt of the connecting hole with trolley.The connecting hole of this prioritization scheme is arranged, and avoids
It relatively rotates between trolley and Return spring, keeps the deformation of trolley coaxial with Return spring, guarantee to pull back reliable
Property.
The utility model has the following beneficial effects: fixing trolley middle section by fixed insulator, deformation is made to pass through temperature
Compensation device is stretched or is shunk to both ends, and Return spring deforms, and after temperature is restored, trolley both ends are in bullet of pulling back
It is resetted under the action of spring, after avoiding trolley because of variation of expanding with heat and contract with cold, relative to workshop beam mechanism longitudinal direction occurs for trolley
Displacement.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；

Specific embodiment
In order to clarify the technical characteristics of the invention, being illustrated below by specific embodiment to this programme.
A kind of returning device of steel body trolley as shown in Figure 1, including being fixed in consolidating for 2 middle section of trolley and fixed setting
Determine insulator 1, and the withdrawing device at 2 both ends of trolley is set, fixed insulator 1 is located at the interposition of trolley overall length
It sets.In order to simplify structure, reduce space occupied, fixed insulator 1 is fixed on the bracket for installing common insulator 7 by the present embodiment
On 8, fixed insulator and trolley are relatively fixed, and fixed insulator is fixed together with fixed bracket, avoids wiping
With expanding with heat and contract with cold axial displacement occurs for line middle section.
Withdrawing device includes the fixing buckle 5 of fixed setting and one end is connect with the fixing buckle 5, the other end passes through absolutely
The Return spring 4 that edge connecting plate 6 is connect with wiping thread end.Fixing buckle 5 includes the fixing seat affixed with workshop, and with it is described
The affixed hook of fixing seat, the hook are connect with Return spring 4.At least two are offered along trolley on insulation connecting plate 6
The connecting hole of length direction arrangement, insulation connecting plate are connect by passing through the bolt of the connecting hole with trolley, the present embodiment
Middle connection hole number is 4.
Fixed insulator selects resin or porcelain as insulated part, the comprehensive trolley specification of Return spring pulling force size, absolutely
The factors such as edge intensity are selected between 2000-3000kp, avoid damaging insulator.
Withdrawing device is arranged at the steel body trolley both ends of driving power supply in the returning device of the present embodiment, when steel body trolley
When the physical change expanded with heat and contract with cold by environment temperature, the temperature compensation means 3 at both ends is stretched or is shunk, withdrawing device
Spring can generate corresponding to the opposite force that occurs after slip variation, after the physical change of slip, in spring opposite force
Under the action of, this section of slip will be restored to the position relative to workshop beam originally, also eliminate trolley relative to workshop machine
Structure displacement generally longitudinally concentrates on a certain section of longitudinal stress.
Certainly, above description is also not limited to the example above, and technical characteristic of the utility model without description can lead to
It crosses or realizes that details are not described herein using the prior art；Above embodiments and attached drawing are merely to illustrate the technology of the utility model
