Description
Technical field
The utility model relates to crane power supply technique field more particularly to a kind of crane power supply collector-block connection knots
Structure.
Background technique
Frequently with the upper gliding style power supply mode of current-collector and slip cooperation, slip supply voltage is 380V for crane power supply.It is logical
It crosses collector-block and slip friction skid is realized and powered at a distance to crane, when collector-block service wear reaches 2/3
It needs replacing.When replacing collector-block, needs first to remove two line pigtails of current-collector, then current-collector slide plate is removed again,
Finally removing 4 screws that collector-block is connect with current-collector slide plate makes to be completely separated.It needs successively when returning dress by new collection
Electric appliance sliding block is fixed on current-collector slide plate, then current-collector slide plate is fixed on current-collector pedestal, last connecting line pigtail, ability
It enough completes collector-block and replaces task.Conventional collector-block replacement operation needs 3 people to spend nearly 3 hours, service personnel
Station need to be fastened the safety belt in operation in slip maintenance cage, operating time length, large labor intensity, risk are high, when crane number
When measuring more, this work seriously constrains going on smoothly for production.
Summary of the invention
The utility model provides a kind of crane power supply collector-block connection structure, solves collector-block replacement consumption
The problem of duration, shortens the upkeep operation time, ensures the safety of upkeep operation personnel and the operating rate of crane equipment.
In order to achieve the above object, the utility model is implemented with the following technical solutions:
A kind of crane power supply collector-block connection structure, including collector-block and current-collector slide plate；The current-collector
The cross section of sliding block is made of the trapezoid cross section on top and the rectangular section of lower part, and the bottom edge side length of trapezoid cross section is less than top margin side
It is long, again smaller than the side length for the rectangular section being connected；The current-collector slide plate is separate structure, by broken line slide plate and linear slide
Composition, the cross section of broken line slide plate are made of the oblique section in lower part, the oblique section of horizontal segment and top, the oblique section in middle and lower part and collector-block
The side waist in upper trapezoid section fits, and horizontal segment and the top surface in collector-block upper trapezoid section fit；Linear slide
The other side waist of lower part and collector-block trapezoid cross section fits, and the top of linear slide and the oblique section in top of broken line slide plate are logical
It crosses and is bolted.
The trapezoid cross section is isosceles trapezoid section.
The bolt is at least 2 groups, longitudinally disposed along collector-block.
Compared with prior art, the utility model has the beneficial effects that
After collector-block connection structure described in the utility model, dismounting installation collector-block is very convenient, more
Changing the operation of three-phase collector-block only needs 2 people to spend about 45 minutes, substantially reduces the repair time, and it is strong to reduce labour
Degree, ensure that production direct motion, practical effect is fine.
Detailed description of the invention
Fig. 1 is a kind of main view of crane power supply collector-block connection structure described in the utility model.
Fig. 2 is the left view of Fig. 1.
In figure: 1. collector-block, 2. broken line slide plate, 3. linear slide
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing:
As shown in Figure 1 and Figure 2, a kind of crane power supply collector-block connection structure described in the utility model, including current-collector
Sliding block 1 and current-collector slide plate；The cross section of the collector-block 1 is by the trapezoid cross section on top and the rectangular section group of lower part
At the bottom edge side length of trapezoid cross section is less than top margin side length, again smaller than the side length for the rectangular section being connected；The current-collector slide plate
For separate structure, be made of broken line slide plate 2 and linear slide 3, the cross section of broken line slide plate 2 by the oblique section in lower part, horizontal segment and on
The oblique section composition in portion, the oblique section in middle and lower part and the side waist in 1 upper trapezoid section of collector-block fit, and horizontal segment and current-collector are sliding
The top surface in 1 upper trapezoid section of block fits；The lower part of linear slide 3 and the other side waist of 1 trapezoid cross section of collector-block are affixed
It closes, the top of linear slide 3 is connect with the oblique section in the top of broken line slide plate 2 by bolt 4.
The trapezoid cross section is isosceles trapezoid section.
It is at least 2 groups of the bolt 4, longitudinally disposed along collector-block 1.
It is as follows using a kind of installation and replacement process of crane power supply collector-block connection structure described in the utility model: first
First production current-collector slide plate and the collector-block 1 matched；Match on broken line slide plate 2 and linear slide 3 and bore 2 bolts hole,
After broken line slide plate 2, linear slide 3 are installed to 1 two sides of collector-block, the two is fixedly connected with bolt 4, collector-block
1 is linked together with current-collector slide plate by swallowtail trough structure.The bolt of 2 connections need to be only unclamped when replacing collector-block
4 can draw it out, and operation is very easy, time saving and energy saving.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its design is subject to equivalent substitution or change, should be covered within the scope of the utility model.
