Abstract
The utility model discloses seaming of an upper connection shaft. The seaming of the upper connection shaft is characterized in that connection bolts are respectively connected with two ends of the connection shaft; a bracket is sleeved at the middle part of the connection shaft, and reinforcing ribs are respectively arranged between two sides of a bracket sleeve and the connection shaft. By the arrangement, a steel rod is adopted to weld with a seamless tube; the seaming of the upper connection shaft is used in connection of a tripod and a hydraulic cylinder, and a phenomenon that service lives of other parts are affected by cracking of the upper connection shaft is avoided.
Description
Technical field
The utility model relates to a kind of for dumping truck upper joint spider and cylinder connecting device, is a kind of upper adapter shaft seam of spider assembly specifically.
Background technology
The connecting device of two set square seam on the dumping truck, it is a main stressed member in whole lifting mechanism, the Casting Parts that traditional upper adapter shaft seam is adopted, Casting Parts has the defective of pore, sand holes inevitable, the phenomenon that in use can occur rupturing has affected service life of other parts.
Summary of the invention
The purpose of this utility model is that a kind of upper adapter shaft seam that connects dumping truck spider and oil cylinder is provided.
For achieving the above object, the utility model is respectively equipped with tie bolt at the two ends of adapter shaft, and carrying sleeve is located at the middle part of adapter shaft, is respectively equipped with reinforced rib between the both sides of carrying sleeve and adapter shaft.
By above setting, the utility model adopts round steel and seamless tube welding, uses in being connected of the spider of tip-up lorry and hydraulic ram, and having avoided upper adapter shaft to rupture affects other parts phenomenon in service life.
Description of drawings
Now by reference to the accompanying drawings the utility model is described further.
Fig. 1 structural representation of the present utility model.
Among the figure: 1, adapter shaft, 2, tie bolt, 3, carrying sleeve, 4, reinforced rib.
The specific embodiment
As shown in Figure 1, the utility model is respectively equipped with tie bolt 2 at the two ends of adapter shaft 1, and carrying sleeve 3 is located at the middle part of adapter shaft 1, is respectively equipped with reinforced rib 4 between the both sides of carrying sleeve 3 and adapter shaft 1.By above setting, the two ends of adapter shaft 1 of the present utility model are connected with spider respectively, and carrying sleeve 3 is connected with the piston rod of hydraulic ram, and are more safe and reliable than adapter shaft in traditional casting, are difficult for fracture.
