Abstract
The utility model discloses a rail pressing device which comprises a base, an upper cover plate, a bolt and a nut, wherein the base is symmetrically provided with upper convex blocks and the upper convex blocks are obliquely arranged; the upper cover plate is provided with lower convex blocks which correspond to the upper convex blocks; and the bolt passes through the upper convex blocks and the lower convex blocks and the upper cover plate is fixedly arranged on the base through the nut. According to the rail pressing device disclosed by the utility model, the upper cover plate is provided with the lower convex blocks and the base is provided with the upper convex blocks; and when the upper cover plate and the base relatively slide, a rail is tightly clamped by thickness differences increased among the lower convex blocks and the base, and among the upper convex blocks and the upper cover plate, so as to prevent the rail from displacing and achieve the bidirectional stopping effect.
Description
Technical field
The utility model relates to a kind of rail pressing device, belongs to crane runway anchor fitting technical field.
Background technology
Maximization day by day, variation along with hoisting and handling equipment; Structural system such as crane and crane girder brings more and more harsher requirement to its working environment and service conditions, and how to select good device for fixing running tracks be the crane safe operation with reduce the important assurance of keeping in repair according to various structure and crane form and working environment.Existing crane rail road anchor fitting is through railway clamp is fixed up through bolt etc. between upper cover plate and base more basically; This anchor fitting can play certain fixation; But its shortcoming is: device can not be resisted bigger side direction moment; And the track appearance of a street is slided before and after being prone to, and causes whole anchor fitting loosening, has a strong impact on the safe operation of crane.
Summary of the invention
The utility model is in order to overcome the deficiency that prior art exists, and a kind of simple in structure, rail pressing device that tightness is good is provided.
The utility model can be achieved through taking following technical scheme:
A kind of rail pressing device; Comprise base, upper cover plate, screw bolt and nut, be arranged with upper protruding block on the said base, said upper protruding block fore-and-aft tilt; Said upper cover plate is provided with and the cooresponding lower protruding block of upper protruding block, and said bolt passes upper protruding block and lower protruding block and through nut upper cover plate is fixed on the base.
On the basis of the above, the said upper protruding block of the utility model is provided with through hole, and said lower protruding block is provided with shrinkage pool, and said bolt passes through hole and shrinkage pool and through nut upper cover plate is fixed on the base.
Be extended with anti-skidding solid piece on the lateral of the said upper protruding block of the utility model, can prevent upper cover plate on base sway with bear side direction moment.
In order to prevent nut loosening, reduce noise and make track and girder steel Elastic Contact, be placed with single pad and spring washer between said nut of the utility model and the upper cover plate.
Compared with prior art; The beneficial effect of the utility model is: the utility model is provided with lower protruding block through upper cover plate and base is provided with upper protruding block; When upper cover plate and base will produce slide relative; Utilize the thickness difference that increases between lower protruding block and base and upper protruding block and the upper cover plate that upper cover plate and base are clamped track, be subjected to displacement, reach two-way stopping effect to prevent track.
Description of drawings
Fig. 1 is the structural representation of the rail pressing device of the utility model;
Fig. 2 is the structural representation of the base of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the most preferred embodiment of the utility model is described in detail.
Like Fig. 1, shown in Figure 2; The rail pressing device of the utility model comprises base 1, upper cover plate 2, bolt 3 and nut 4; Be arranged with upper protruding block 11 on the said base 1; Said upper protruding block 11 fore-and-aft tilts, said upper cover plate 2 are provided with and upper protruding block 11 cooresponding lower protruding blocks 21, and said bolt 3 passes upper protruding block 11 and with lower protruding block 21 and through nut 4 upper cover plate 2 is fixed on the base 1; Be extended with anti-skidding solid piece 12 on the lateral of said upper protruding block 11, can prevent upper cover plate 2 on base 1 sway with bear side direction moment.Loosening in order to prevent nut 4, reduce noise and make track and girder steel Elastic Contact, be placed with single pad 5 and spring washer 6 between said nut 4 and the upper cover plate 2.
The said upper protruding block 11 of the utility model is provided with through hole, and said lower protruding block 21 is provided with shrinkage pool, and said bolt 3 passes through hole and shrinkage pool and through nut 4 upper cover plate 2 is fixed on the base 1.
The above person of thought; Be merely the preferred embodiment of the utility model; When the scope that can not limit the utility model enforcement with this; The content of promptly being put down in writing according to the utility model claim and utility model specification sheets has generally been done simple equivalent and has been changed and modification, all still belongs within the utility model claim institute covering scope.In addition, summary partial sum title only is the usefulness that is used for assisting the patent document search, is not the interest field that is used for limiting the utility model.
