Embodiment
It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the utility model can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
In the utility model, in the situation that not doing contrary explanation, Fig. 3, Fig. 5 and Fig. 7 all be take in the noun of locality of use " upper and lower, left and right " is reference.Term " first ", " second " are mainly used in distinguishing different parts or structure, but parts or structure are not specifically limited.
Bearing pin limit stoper as shown in Figure 2 to Figure 3, bearing pin 6 is arranged on fixed plate 7, comprise the baffle plate 2 being arranged on lock shaft 6, the axle head 61 of bearing pin 6 is provided with the first step 62 of protrusion, axle head 61 forms the first groove with first step 62, the lower end of baffle plate 2 is placed in the first groove, and the left side of baffle plate 2 is near fixed plate 7, and right side is against first step 62.Like this, when bearing pin 6 is axially moved to the left, first step 32 passes to baffle plate 2 by power, then by baffle plate, power is passed to fixed plate 7, in power transmittance process, the link (be generally bolt, in description below, replace link with bolt) that connects baffle plate 2 does not stress, changed bearing pin limit stoper by bolt strained present situation, therefore, bolt can not be pulled off, and the reliability of bearing pin limit stoper is higher.The shape of fixed plate 7 can be varied, can be for square or circular, or other shape, at this, do not do concrete restriction, the size of fixed plate 7 also can be determined as required.
In technique scheme, bearing pin limit stoper also comprises the block 1 being fixedly installed on fixed plate 7, particularly, block 1 is fixed on the right side of fixed plate 7, by Placements such as welding or bolts, be fixed on fixed plate 7, in one embodiment, the lower end in contact of the upper end of baffle plate 2 and block 1, like this, when bearing pin 6 rotates, axle head 61 passes to power the lower end of baffle plate 2, by baffle plate 2, power is passed to block 1 again, due to baffle plate 2 and axle head 61, block 1 is face contact, like this can be by the rotation of block 1 restriction bearing pin 6, therefore in power transmittance process, the bolt that connects baffle plate 2 does not stress yet.
In another kind of embodiment, the lower end of block 1 is provided with outstanding second step 63, between second step 63 and fixed plate 7, form the second groove, the upper end of baffle plate 2 is placed in the second groove, the right side of baffle plate 2 is resisted against in second step 63 simultaneously, by second step 63 is set, when bearing pin 6 moves right, second step 63 can block baffle plate 2, restriction bearing pin 6 moving axially to the right.
In technique scheme, connect the link of baffle plate 2 for baffle plate 2 is limited in to bearing pin 6, one end of link is fixed on bearing pin 6.Particularly, link is preferably bolt 4, baffle plate 2 is provided with bolt hole, bolt 4 is arranged on baffle plate 2, bolt 4 is provided with packing ring 3, distance between packing ring 3 and baffle plate 2 is greater than first step 62 on axle head 61 and the distance between baffle plate 2, and in the time of can guaranteeing that like this bearing pin 6 is moved to the left, bolt 4 does not stress.In addition, also can cancel packing ring 3, make to have gap between the junction surface of bolt 4 and baffle plate 2, this gap is greater than first step 62 on axle head 61 and the distance between baffle plate 2 right sides, it should be noted that, link can be with other links such as screws.
In one embodiment, for the ease of protection and fixing bolt 4, avoid bolt 4 loosening, raising working life, between bolt 4 and baffle plate 2, also sleeve 5 can be set, coordinating between baffle plate 2 and sleeve 5 is Spielpassung.When bearing pin 6 circumferentially moves or rotates, the gap between bolt 4 and sleeve 5 can guarantee that bolt 4 is not subject to shearing force, and bears the peripheral force from bearing pin 6 by baffle plate 2.
It should be noted that, in another kind of embodiment, as shown in FIG. 6 and 7,
For simplifying the structure of bearing pin limit stoper, the sleeve 5 being placed between bolt 4 and baffle plate 2 can be cancelled, the packing ring 3 being placed on bolt 4 also can be cancelled, cooperation between bolt 4 and bolt hole is Spielpassung, the bolt 4 of having avoided being to a great extent fixed on bearing pin 6 is subject to the shearing force from baffle plate 2, thereby avoid bolt 4 to damage, stop potential safety hazard.In addition,, in technique scheme, on bolt 4, be also provided with the locking device for preventing that bolt 4 from getting loose.
The bearing pin limit stoper of said structure, tool has the following advantages:
First, bolt can not be pulled off and cut off, and functional reliability is high.The bearing pin limit stoper of said structure, 4, bolt plays the effect that anti-baffle plate 2 comes off, when bearing pin 6 axially or circumferentially moves, by baffle plate 2, bear extruding force and shearing force, therefore, can not damage bolt 4, effectively avoid because bolt 4 damages the security incident causing, functional reliability is good.
Secondly, simple in structure, with low cost.The bearing pin limit stoper of said structure, bearing pin 6 is arranged on fixed plate 7, be arranged at baffle plate 2 on fixed plate 7 with for being connected the bolt 4 of baffle plate 2 and bearing pin 6, structure is comparatively simple, cost is comparatively cheap.
Again, easy accessibility, is suitable for and promotes the use.The bearing pin limit stoper of said structure, during dismounting, only need back-out bolt 4 from baffle plate 2, just can take out baffle plate 2, thereby complete the dismounting of bearing pin limit stoper.During installation, first baffle plate 2 is positioned over to relevant position, then bolt 4 is tightened, complete the installation of bearing pin limit stoper, therefore, dismounting all more for convenience, is suitable for and is promoted the use of.
On the other hand, the utility model also proposes a kind of engineering machinery, and described engineering machinery comprises bearing pin limit stoper as above.
Further, engineering machinery comprises pump truck, and bearing pin limit stoper is arranged on the jib of pump truck, as the bearing pin at the two ends of jib support cylinder all can be used above-mentioned bearing pin limit stoper.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
