Abstract
The utility model provides a loader swing arm hinge pin locking device. The loader swing arm hinge pin locking device comprises a hinge pin pressing plate arranged on a swing arm hinge pin, a swing arm is connected with the swing arm hinge pin through a liner, the hinge pin pressing plate is connected with a loader frame through a threaded base, a bolt arranged above the hinge pin pressing plate is connected with the threaded seat through a big flat mat. The loader swing arm hinge locking device overcomes defects of the prior art, can reduce the probability of the phenomenon that the hinge pin dashes out, and improves safety performance, and meanwhile, the loader swing arm hinge pin locking device has the advantages of being simple in structure, convenient to machine and manufacture, and reliable in performance.
Description
Technical field
The utility model relates to a kind of loading arm lock clasp device, belongs to technical field of engineering machinery.
Background technology
It is the normal a kind of type of attachment that adopts on the loader product that bearing pin connects.At present, the structure that the swing arm bearing pin of loader contacts with vehicle frame with the bearing pin pressing plate usually and locks with bolt on the market, as shown in Figure 1, swing arm 3 is by lining 2 and 7 assemblings of swing arm bearing pin, swing arm bearing pin 7 is locked together by bearing pin pressing plate 6 and vehicle frame 1, and utilize bolt 4 and bullet pad 5 to fix, but finally realize swing arm 3 purpose that moving arm bearing pin 7 rotatablely moves on vehicle frame 1.
But there are the following problems for this structure: when 7 rotations of swing arm 3 moving arm bearing pins, if bolt 4 is inconsistent with the gap of bearing pin pressing plate 6, when 0.05～0.2mm displacement takes place in swing arm bearing pin 7, the alternating force identical with swing arm bearing pin 7 that may cause bearing pin pressing plate 6 to produce with bolt 4 contacts site.Under the effect of long alternating force, bolt 4 easily produces loosening, after bolt 4 becomes flexible, very easily cause swing arm bearing pin 7 to deviate from, in a single day this swing arm bearing pin 7 is deviate from, and swing arm 3 will lose support, equipment will separate with vehicle frame 1, and gently then influence is normal uses, and will be heavy then cause security incident.
The utility model content
The technical problems to be solved in the utility model provides and a kind ofly can reduce the probability that bearing pin is scurried outward, improves safety, and the loading arm lock clasp device of simple in structure, convenient processing and manufacture, dependable performance.
In order to solve the problems of the technologies described above, the technical solution of the utility model provides a kind of loading arm lock clasp device, comprise the bearing pin pressing plate of being located on the swing arm bearing pin, swing arm is connected with the swing arm bearing pin by lining, it is characterized in that: described bearing pin pressing plate is connected with vehicle frame by threaded block, and the bolt of being located at described bearing pin pressing plate top is connected with threaded block by big flat washer.
Preferably, be provided with the bullet pad between described bolt and the described big flat washer.
The gap that 2mm preferably, is arranged between described bolt and the described bearing pin pressing plate.
A kind of loading arm lock clasp device that the utility model provides is by welding threaded block at vehicle frame, make bolt contact and not contact with the bearing pin pressing plate with threaded block, when the swing arm bearing pin is subjected to alternating stresses, bolt is not subjected to the effect of this alternating stresses, bolt also just is difficult for loosening, thereby the probability that the reduction bearing pin is scurried outward improves whole safety factor.
The device that the utility model provides has overcome the deficiencies in the prior art, can reduce the probability that bearing pin is scurried outward, improves safety, and has the characteristics of simple in structure, convenient processing and manufacture, dependable performance.

The specific embodiment
For the utility model is become apparent, now with a preferred embodiment, and conjunction with figs. is described in detail below.
A kind of loading arm lock clasp device schematic diagram that Fig. 1 provides for the utility model, described a kind of loading arm lock clasp device comprises the bearing pin pressing plate 6 that is contained on the swing arm bearing pin 7, swing arm 3 is by lining 2 and 7 assemblings of swing arm bearing pin; Bolt 4 is positioned at bearing pin pressing plate 6 tops, directly do not contact with bearing pin pressing plate 6, but at first at vehicle frame 1 welding threaded block 9, bolt 4 is tightened assembling with threaded block 9, and bolt 4 is not contacted with bearing pin pressing plate 6, leaves the gap d about 2mm.And at bolt 4 and 6 increases of bearing pin pressing plate, one big flat washer 8,8 of the big flat washer of this moment play the barricade effect.8 of bolt 4 and big flat washer have bullet pad 5.Therefore when swing arm bearing pin 7 was subjected to alternating stresses, bolt 4 was not subjected to the effect of this alternating stresses, and bolt 4 also just is difficult for loosening, thereby reduces the probability that bearing pin is scurried outward, improves whole safety factor.
A kind of loading arm lock clasp device that the utility model provides contacts and does not contact with the bearing pin pressing plate with threaded block by bolt, has solved the problem that bearing pin is scurried outward, has characteristics such as simple in structure, that intention is novel, the processing and manufacturing cost is low.
