Abstract
The invention discloses an overtravel-proof rail channel limiter for a crane, comprising a C-beam 1, a fixing lock block 2, a driven lock block 3, a threaded hole 4, a screw 5 and a pusher 6. The C-beam 1 is made by cutting cylindrical steel, the fixing lock block 2 and the C-beam are integrated, the driven lock block 3 is of T-shaped structure, a bottom surface of the driven lock block 3 is an oblique surface, the threaded hole 4 enables a standard No. 16 nut to be welded to the lower portion of the C-beam 1, the screw 5 is a standard No. 16 screw, and the pusher 6 that is of triangular prism structure filling between the screw 5 and the driven lock block 3. The overtravel-proof rail channel limiter has the advantages of operational convenience and structural stability.
Description
Technical field
The present invention relates to a kind of crane equipment, particularly relate to a kind of crane anti-overtravel rail groove stop.
Background technology
At present, hoisting machinery is widely used in the lifting of various material, transports, in the operation such as handling, can reduce labor intensity, improve production efficiency, for at the gantry crane of outside work, after the setting of rail groove, the mode of rail groove two end many employings welding steel limits the stroke of crane, and the steel plate that early stage is welded on rail groove when later stage track length needs to extend is difficult to remove, and the rail groove welding in later stage is affected the most accordingly and causes solder side rough.
Summary of the invention
For solving the defect of prior art, the invention discloses a kind of crane anti-overtravel rail groove stop easy to operate, constitutionally stable.
The invention discloses a kind of crane anti-overtravel rail groove stop, including: C-type steel, fixing lock dog, driven lock dog, screwed hole, screw, pushing block, described C-type steel is that cylinder steel cutting processing forms, described fixing lock dog and C-type steel are an entirety, described driven lock dog is T font structure, and described driven lock dog bottom surface is inclined plane, described screwed hole is that No. 16 cap nuts of standard are welded on C-type steel bottom, described screw is No. 16 screws of standard, and described pushing block is that triangular prism structure is filled in the middle of screw and driven lock dog.
Owing to using technique scheme, the present invention has a following advantageous benefits:
1, easy to operate；
2, Stability Analysis of Structures.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention a kind of crane anti-overtravel rail groove stop.
Wherein: 1-C shaped steel；2-fixes lock dog；The driven lock dog of 3-；4-screwed hole；5-screw；6-pushing block.
Detailed description of the invention
As shown in Figure 1, the invention discloses a kind of crane anti-overtravel rail groove stop, including: C-type steel 1, fixing lock dog 2, driven lock dog 3, screwed hole 4, screw 5, pushing block 6, described C-type steel 1 forms for cylinder steel cutting processing, described fixing lock dog 2 is an entirety with C-type steel, described driven lock dog 3 is T font structure, and described driven lock dog 3 bottom surface is inclined plane, described No. 16 cap nuts that screwed hole 4 is standard are welded on C-type steel 1 bottom, described No. 16 screws that screw 5 is standard, it is middle with driven lock dog 3 that described pushing block 6 is filled in screw 5 for triangular prism structure.
The present invention is implemented: the present invention be clamped on portal crane rail groove with coordinating of fixing lock dog 2 by driven lock dog 3, tighten screw 5, screw 5 promotes pushing block 6 to move, pushing block 6 is by the jacking of driven lock dog 3, the motion of driven lock dog 3 shortens and fixes the distance of lock dog 2, thus reaching the effect present invention being fastened on rail groove, the present invention has advantage easy to operate, constitutionally stable.
Last it is noted that above example only in order to the present invention is described and and unrestricted technical scheme described in the invention；Therefore, although this specification with reference to each above-mentioned embodiment to present invention has been detailed description, but, it will be understood by those within the art that, still the present invention can be modified or equivalent；And all are without departing from the technical scheme of the spirit and scope of the present invention and improvement thereof, it all should be contained in scope of the presently claimed invention.
Claims (1)
1. a crane anti-overtravel rail groove stop, including: C-type steel 1, fixing lock dog 2, driven lock dog 3, screwed hole 4, screw 5, pushing block 6, it is characterized in that: described C-type steel 1 forms for cylinder steel cutting processing, described fixing lock dog 2 is an entirety with C-type steel, described driven lock dog 3 is T font structure, and described driven lock dog 3 bottom surface is inclined plane, described No. 16 cap nuts that screwed hole 4 is standard are welded on C-type steel 1 bottom, described No. 16 screws that screw 5 is standard, it is middle with driven lock dog 3 that described pushing block 6 is filled in screw 5 for triangular prism structure.
