Detailed Description
The embodiments of the invention will be described in detail below with reference to fig. 1 to 3, but the invention can be implemented in many different ways as defined and covered by the claims.
According to the description of the background art can discover, use the crow bar to remove 10 in-process of balancing piece at the staff, the crow bar is as the fulcrum with the bottom of crank 11's spout, if when the spout bottom surface is wet smooth, the situation that the crow bar skidded appears easily for there is the potential safety hazard when the staff operates, the utility model aims at providing a can move about and safe and reliable's removal support as the application of force fulcrum of crow bar to this problem, improves staff's operational safety nature.
With reference to fig. 1 to 3, the movable balance block moving bracket provided by the present invention comprises a positioning plate 2 capable of falling into a chute of a crank 11, wherein the positioning plate 2 is provided with a longitudinal through hole 2a, an upper U-shaped frame 3 is welded on the upper portion of the positioning plate 2, a locking block 4 is welded on the upper portion of the upper U-shaped frame 3, a bolt 5 is arranged on the middle portion passing through the upper portion of the upper U-shaped frame 3 and the locking block 4, and the bolt 5 can be matched with a gasket 6 and locked by a nut; the length of the locking block 4 is greater than the width of the upper opening of the crank 11, so that the locking block 4 can exert force on the top surface of the sliding groove of the crank 11; the diameter of the pad 6 is larger than the width of the upper opening of the crank 11 so that the pad 6 can eat up the upper side of the crank 11.
According to the structure of the above embodiment, it can be found that, since the locking block 4 is locked on the crank 11 through the matching of the bolt 5, the gasket 6 and the nut, and the locking block 4 is welded with the upper U-shaped frame 3, and the upper U-shaped frame 3 is welded with the positioning plate 2, the position of the positioning plate 2 is fixed, and the worker can use the through hole 2a on the positioning plate 2 as the force application fulcrum of the crow bar, although this embodiment has a progress compared with the prior art, because the loose bolt is connected between the balance weight 10 and the crank 11, the positioning plate 2 cannot extend into the lower part of the balance weight 10 for a longer distance, after the balance weight 10 is pried for a certain distance, the worker is required to loose the nut matched with the bolt 5 to move the positioning plate 2, so that the operation continuity is insufficient, and the operation time is prolonged while the safety is improved.
With reference to fig. 1 to 3, an L-shaped movable plate 1 is movably placed on the upper portion of the positioning plate 2, the L-shaped movable plate 1 is provided with a longitudinal insertion hole 1a, and the lower portion of the L-shaped movable plate 1 is provided with a chute 1 b; a lower U-shaped frame 7 is welded at the lower part of the positioning plate 2, a wedge block 8 is movably arranged in the lower U-shaped frame 7, and the bottom surface of the wedge block 8 is connected with the bottom surface of the lower U-shaped frame 7 through a spring 9; the wedge-shaped block 8 can be wedged with the inclined groove 1b through the through hole 2a of the positioning plate 2.
The utility model discloses an in the above-mentioned embodiment, utilize jack 1a on the L shape fly leaf 1 to just can make the balance adjustment operation have the continuation as the application of force fulcrum of crow bar, the staff only need promote L shape fly leaf 1 after prizing certain distance with balancing piece 10 and make its below that stretches into balancing piece 10 can obtain another suitable fulcrum.
Specifically, because the wedge block 8 connected with the spring 9 is arranged in the lower U-shaped frame 7, under the elastic force of the spring 9, the wedge block 8 can penetrate through the through hole 2a of the positioning plate 2 and be wedged with the inclined groove 1b at the lower part of the L-shaped movable plate 1, and the wedging mode enables a worker to overcome the friction force between the inclined surface of the inclined groove 1b and the inclined surface of the wedge block 8 when pushing the L-shaped movable plate 1, so as to overcome the elastic force of the spring 9, but the L-shaped movable plate 1 cannot back up under the elastic force of the spring 9, when the worker extends a prying bar into the insertion hole 1a of the L-shaped movable plate 1, the insertion hole 1a can be used as a force application fulcrum of the prying bar, and when the balance block 10 is pried for a certain distance and a new fulcrum needs to be found, the worker only needs to push the.
To sum up, this utility model mainly has utilized the shape characteristic of wedge 8 to make its chute 1b cooperation with L shape fly leaf 1 for L shape fly leaf 1 can only advance and can't fall back, just so provides activity and safe and reliable's application of force fulcrum for the crow bar, and the staff uses this utility model and the cooperation of crow bar to remove balancing piece 10 and just can effectively eliminate the potential safety hazard that exists in the operation.
Finally, it should be noted that the utility model is only suitable for the situation that the staff uses the crow bar to carry out the crank balancing operation.
