Abstract
The utility model discloses a novel rail pressing machine comprising a screw, a nut, an upper cover plate and a base, wherein the base is a wedge-shaped body, one edge of the base extends upward to form a trapezoid upper boss, and a through hole is arranged in the middle of the boss. The lower portion of the through hole extends to two sides to form a screw groove. The upper plate is a wedge-shaped body, and a trapezoid lower boss is formed at the bottom of the upper plate and the lower boss corresponds to the trapezoid upper boss. A screw hole is arranged in the trapezoid lower boss, one end of the screw is fixed in the screw groove, and the other end of the screw penetrates through the through hole and the screw hole and fixes the upper cover plate on the base through the bolt. Due to the fact that the trapezoid lower boss is arranged on the upper cover plate and the trapezoid upper boss is disposed on the base, when relative sliding is generated between the upper cover plate and the base, the upper cover plate and the base tightly clamp the rail by using increased thickness difference between the lower boss and the base, and the upper box and the upper cover plate. Therefore, the rail is prevented from displacement and two-way backstop effect is achieved.
Description
Technical field
The utility model relates to a kind of novel 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 provides a kind of novel rail pressing device in order to overcome the deficiency that prior art exists.
The utility model can be achieved through taking following technical scheme:
A kind of novel rail pressing device comprises bolt, nut, upper cover plate and base, and said base is a sphenoid; It has extended upward trapezoidal convex platform on one side; The center has through hole, and the bottom of said through hole extends to form bolt slot to both sides, and said upper cover plate is a sphenoid; Its bottom forms and the cooresponding trapezoidal lower bulge of trapezoidal convex platform; Offer bolt hole on the said trapezoidal lower bulge, an end of said bolt is fixed in the bolt slot, and the other end passes through hole and bolt hole and through nut upper cover plate is fixed on the base.
On the basis of the above, a side direction of the said upper cover plate of the utility model extends below the formation baffle plate.
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 trapezoidal lower bulge through upper cover plate and base is provided with trapezoidal convex platform, when upper cover plate and base will produce slide relative, utilizes the thickness difference that increases between lower bulge and base and convex platform and the upper cover plate that upper cover plate and base are clamped track; To prevent that track is being subjected to displacement; Reach two-way stopping effect, simultaneously, the cooperatively interacting of trapezoidal convex platform and trapezoidal lower bulge; Make whole rail pressing device can resist bigger side direction moment, the safety factor of whole rail pressing device is improved.In addition, the utility model is relatively simple for structure, can omit loaded down with trivial details erection procedure.
Description of drawings
Fig. 1 is the structural representation of the novel rail pressing device of the utility model;
Fig. 2 is the structural representation of the upper cover plate of the utility model;
Fig. 3 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.
To shown in Figure 3, the novel rail pressing device of the utility model comprises bolt 1, nut 2, upper cover plate 3 and base 4 like Fig. 1; Said base 4 is a sphenoid, on one side it has extended upward trapezoidal convex platform 5, the center has through hole 6; The bottom of said through hole 6 extends to form bolt slot 7 to both sides; Said upper cover plate 3 is a sphenoid, and its bottom forms and trapezoidal convex platform 5 cooresponding trapezoidal lower bulges 8, offers bolt hole 9 on the said trapezoidal lower bulge 8; One end of said bolt 1 is fixed in the bolt slot 7; The other end passes through hole 6 and with bolt hole 9 and through nut 2 upper cover plate 3 is fixed on the base 4, utilizes the plane of structure restriction that forms between resistance that upper cover plate 3 and base 4 these two sphenoids produce when relative motion and trapezoidal convex platform 5 and the trapezoidal lower bulge 8, makes that track is logical to be fixed on the rail pressing device restfully.In order to make upper cover plate 3 and base 4 more compact structure and to bear bigger side direction moment, a side direction of said upper cover plate 3 extends below and forms baffle plate 10, and this baffle plate 10 is pressed in a side of base 4 in use and bears moment.
In order to prevent nut loosening, reduce noise and make track and girder steel Elastic Contact, be placed with single pad 11 and spring washer 12 between said nut 2 of the utility model and the upper cover plate 3.
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.
