Abstract
The utility model discloses a novel rail-pressing machine which comprises a bolt, a nut, an upper cover plate and a base. The upper cover plate is a wedge block and the bottom surface of the upper cover plate forms a downward-inclined convex block along the opposite direction of an inclination angle. The base is an inverted wedge block and the top surface of the base forms an upward-inclined convex block which is matched with the downward-inclined convex block along the opposite direction of the inclination angle. The upper cover plate covers the base. The bolt penetrates the base and the upper cover plate and fixes the upper cover plate on the base through the nut. Due to the facts that the upper cover plate is provided with the downward-inclined convex block and the base is provided with the upward-inclined convex block, when relative sliding is generated between the upper cover plate and the base, the rail is tightly clamped by the upper cover plate and the base by means of the added thickness difference between the downward-inclined convex block and the base and the upward-inclined convex block and the upper cover plate, and thus the displacement of the rail is prevented and a two-way backstop effect is achieved. In addition, the upward-inclined convex block and the downward-inclined convex block match with each other, and thus the entire rail-pressing machine can resist great lateral torques so that the safety coefficient of the entire rail-pressing machine is raised.
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; Comprise bolt, nut, upper cover plate and base, said upper cover plate is a wedge, and opposite sense forms the projection that has a down dip along the angle of inclination in its bottom surface; Said base is one to fall wedge; Opposite sense forms the projection that tilts cooperate with the projection that has a down dip to its end face along the angle of inclination, and said upper cover plate covers on the base, and said bolt passes base and upper cover plate and through nut upper cover plate is fixed on the base.
On the basis of the above, the said upper cover plate of the utility model is provided with slotted eye, and said base is provided with and the corresponding shrinkage pool of slotted eye, and said bolt passes shrinkage pool and slotted eye and through nut upper cover plate is fixed on the base.
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 have a down dip projection and base through upper cover plate and is provided with the projection that tilts, and when upper cover plate and base will produce slide relative, utilizes have a down dip projection and base and the thickness difference that increases between projection and the upper cover plate that tilts that upper cover plate and base are clamped track; To prevent that track is being subjected to displacement; Reach two-way stopping effect, simultaneously, tilt projection with have a down dip the cooperatively interacting of projection; 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 upper cover plate 3 is a wedge, and opposite sense forms the projection 5 that has a down dip along the angle of inclination in its bottom surface, and even wedge is when the left side tilts; 5 of the projections that have a down dip are tilted to the right, if wedge is when the right tilts, 5 of the projections that have a down dip are tilted to the left; Simultaneously, the projection of projection 5 on the bottom surface of wedge that have a down dip is trapezoidal; Said base 4 is one to fall wedge, and its wedge shape with upper cover plate 3 matches, its end face projection 6 that tilts that opposite sense formation cooperates with the projection 5 that has a down dip along the angle of inclination; Even wedge is when the left side tilts, and 6 of the projections that tilt are tilted to the right, if wedge is when the right tilts; 6 of the projections that tilt are tilted to the left; Simultaneously, the projection triangle of projection 6 on the bottom surface of wedge that tilt, hypotenuse or coincidence parallel with trapezoidal hypotenuse; Said upper cover plate 3 covers on the base 4, and said bolt 1 passes base 4 and with upper cover plate 3 and through nut 2 upper cover plate 3 is fixed on the base 4, and at this moment, the projection 6 that tilts contacts with the opposite flank of the projection 5 that has a down dip fully.When upper cover plate 3 slides left, the thickness that has a down dip between projection 5 and the bottom will increase, and prevent the right slip in upper cover plate 3 places; When upper cover plate 3 slided to the right, the Baidu that tilts between projection 6 and the upper cover plate 3 increased, and prevents that upper cover plate 3 from sliding to the right.
In order to prevent nut loosening, reduce noise and make track and girder steel Elastic Contact, be placed with single pad 7 and spring washer 8 between said nut 2 of the utility model and the upper cover plate 3.
Like Fig. 2, shown in Figure 3; The said upper cover plate 3 of the utility model is provided with slotted eye 9; Said base 4 is provided with and slotted eye 9 corresponding shrinkage pools 10; At the bottom of the T type end firm banking of said bolt 14 ones, its other end is fixed on upper cover plate 3 on the base 4 with slotted eye 9 and through nut 2 passing shrinkage pool 10.
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.
