Abstract
A connecting structure of a dump car pyriform plate and a hinge pin is characterized in that the pyriform plate is a fork pyriform plate, notches are symmetrically arranged at one end of the hinge pin, the pyriform plate is matched with the hinge pin notches, the other end of the hinge pin is provided with a screw thread, and a nut is arranged for being matched with the screw thread of the hinge pin. According to the connecting structure of the dump car pyriform plate and the hinge pin, the pyriform plate adopts the fork pyriform plate, and a connection way of the pyriform plate with the hinge pin adopts detachable connection; and through the improvement, the load-carrying capacity of the pyriform plate is increased, and disassembly of the hinge pin is convenient.
Description
Technical field
The present invention relates to a kind of dump car pyriform plate and swivel pin linkage structure, belong to technical field of engineering machinery.
Background technique
In the linkage structure of dump car articulated body 3 and Rear frame (see accompanying drawing 1), pyriform plate and swivel pin are welded together, the effect of pyriform plate is the axial displacement of restriction swivel pin, but because swivel pin is stressed larger, pyriform plate is easy to be stressed bending or fracture, affect the quality of fit of swivel pin and other component, produce the abnormal sound when dump car works, even cannot work; Meanwhile, because pyriform plate and swivel pin are welded together, cause to dismantle swivel pin from the bottom up during dismounting swivel pin, but due to the lower end limited space of swivel pin, inconvenient hammering, makes the dismounting of swivel pin very difficult.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of dump car pyriform plate and swivel pin linkage structure, pyriform plate adopts prong pyriform plate, and the Placement employing of swivel pin removably connects; By above-mentioned improvement, add the stress-bearing capability of pyriform plate, facilitate the dismounting of swivel pin.
For achieving the above object, the present invention is realized by following technological means:
A kind of dump car pyriform plate and swivel pin linkage structure, it is characterized in that: pyriform plate is prong pyriform plate, is arranged with notch in swivel pin one end, described pyriform plate coordinates with described swivel pin notch, be provided with screw thread at the described swivel pin the other end, be provided with the screw-thread fit of nut and described swivel pin.
Further:
Described a kind of dump car pyriform plate and swivel pin linkage structure, is characterized in that: described nut is slotted nut.
Described a kind of dump car pyriform plate and swivel pin linkage structure, is characterized in that: described slotted nut cotter pin is locking.
Described a kind of dump car pyriform plate and swivel pin linkage structure, is characterized in that: described slotted nut is hexagonal slotted nut.
The invention has the beneficial effects as follows: a kind of dump car pyriform plate provided by the invention and swivel pin linkage structure, pyriform plate adopts prong pyriform plate, and the Placement employing of swivel pin removably connects; By above-mentioned improvement, add the stress-bearing capability of pyriform plate, facilitate the dismounting of swivel pin.
Accompanying drawing explanation
Fig. 1 is former dump car pyriform plate and swivel pin linkage structure schematic diagram, Fig. 2 dump car pyriform of the present invention plate and swivel pin linkage structure schematic diagram, and Fig. 3 is pyriform plate structure schematic diagram.
Embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
Swivel pin is connected with Rear frame by articulated body 3, because former pyriform plate 1 and former swivel pin 3 are welded together, in addition former pyriform plate 1 is handed over thin, in dump car scraper process, former swivel pin 2 has and rotates and the trend of axial float, thus causes that former pyriform plate 1 is easy stressedly to be bent or fracture; And bring former swivel pin 2 to dismantle the defect of difficulty, the present invention is for addressing the aforementioned drawbacks and the improvement carried out the linkage structure of former pyriform plate 1 and former swivel pin 3.
A kind of dump car pyriform plate and swivel pin linkage structure, it is characterized in that: pyriform plate is prong pyriform plate 4, notch 501 is arranged with in swivel pin 5 one end, pyriform plate 4 coordinates with described swivel pin notch 501, be provided with screw thread at described swivel pin 5 the other end, be provided with the screw-thread fit of nut 6 and described swivel pin.
Further:
Described a kind of dump car pyriform plate and swivel pin linkage structure, is characterized in that: described nut 6 is slotted nut.
Described a kind of dump car pyriform plate and swivel pin linkage structure, is characterized in that: described slotted nut 6 is locking with cotter pin 7.
Described a kind of dump car pyriform plate and swivel pin linkage structure, is characterized in that: described slotted nut 6 is hexagonal slotted nut.
Improvement of the present invention is mainly change former pyriform plate 1 into prong pyriform plate 4 Liang Chu: one, two length being the increase in former swivel pin 2, symmetrical notch 501 is provided with in the one end coordinated with prong pyriform plate 4, add screw thread at the other end, coordinated with the swivel pin 5 after improvement by slotted nut; Like this, both added the intensity of prong pyriform plate, and made again the swivel pin 5 after improvement easily dismantle.
More than show and describe basic principle of the present invention, major character and advantage.The technician of the industry should understand; the design is not restricted to the described embodiments; the principle that the design is just described described in above-described embodiment and specification; under the prerequisite not departing from the design's spirit and scope; the design also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the design.The claimed scope of the design is defined by appending claims and equivalent thereof.
