In application, promoting support needed for determining according to the size of the mining height range of coalcutter, Wo Diliang, rocker arm length and oil cylinder
The length of frame.The length that the total length of lifting bracket is equal to support plate 3 adds the thickness of the first plate body 1 and the second plate body 2, the
Under the premise of the structure snd size of one plate body 1 and the second plate body 2 remain unchanged, pass through selection or the support plate of prefabricated different length
3, the length of the lifting bracket of final molding can be made different.The boss 5 at 3 both ends of support plate and the first plate body 1 and the second plate body 2
It is adapted to grafting and fixation, the process for installing combination is more convenient.First plate body 1 and the second plate body 2 by mounting hole 6 respectively with fuselage
It is connected with rocker arm, keeps the height of rocker arm different, so that coalcutter reaches different mining height ranges.First plate body 1 and the second plate body 2
Structure snd size it is constant, can be obtained by corresponding mold.The support plate 3 of different length can be multiple right by making
The mold answered is obtained by modes such as cutting processings, compared with the prior art makes the unitary mould of multiple lifting brackets,
The support plate 3 that the utility model need to only obtain different length can make the lifting bracket length of final molding different, shorten life
The period is produced, cost is reduced.
Wherein, the length of the boss 5 at 3 both ends of support plate can be less than the length of support plate 3, in support plate 3 and boss 5
Between form step surface, when being plugged and fixed, the plate face of the first plate body 1 and the second plate body 2 with step face contact, plays support respectively
Effect, makes lifting bracket be able to bear bigger pressure, and fixed effect is preferable.
The structure snd size of first plate body 1 and the second plate body 2 can be according to the structure and ruler of connecting pin on fuselage and rocker arm
Very little determination has good connection effect.Illustratively, as shown in Fig. 1, the main body of the first plate body 1 is isosceles trapezoid knot
Structure, middle part are machined with slot 4, and edge setting is machined with a mounting hole 6 on each lug there are three lug.Such as attached drawing 3
Shown, the main body of the second plate body 2 is the sketch plate close to parallelogram sturcutre, and one side is arc, marginal position processing
There are four lug, a mounting hole 6 is machined on each lug.
It is understood that due in the first plate body 1 and the second plate body 2 and the integrally formed lifting bracket of the prior art
Two plate body structures and size and indistinction, the lifting bracket after molding assembly is installed to the process of coalcutter and the prior art mentions
The installation process of the lifting bracket of confession is identical, and existing Assembly part still can be used, be easily installed.
Optionally, support plate 3 is respectively with the first plate body 1 and the second plate body 2 by being welded and fixed, support plate 3 and the first plate
After body 1 and 2 grafting of the second plate body assembling, is realized and fixed by welding manner, easy to operate and fixed effect is preferable.
Further, as shown in attached drawing 1-7, the outer rim of boss 5 is provided with chamfering, and slot 4 is set far from the side of support plate 3
It is equipped with groove, boss 5 forms groove weld after being inserted into slot 4 between groove and chamfering.The schematic diagram of groove weld can join
See attached drawing 7.
So set, the chamfering on boss 5 is opposite with the groove on groove after boss 5 is inserted into groove, up-side down triangle is formed
Groove, molten bath is accumulated in groove when welding, avoids molten bath from trickling, reduces welding difficulty, and can be improved welding
Effect.
Optionally, as shown in Fig. 7, lifting bracket provided by the embodiment of the utility model further includes side plate 7, side plate 7
Both ends are connect with the first plate body 1 and the second plate body 2 respectively, and side plate 7 is perpendicular to support plate 3.By adding side plate 7, side plate 7 is risen
Lifting bracket is set to have stronger bearing capacity to supporting role.And side plate 7 can be born multidirectional perpendicular to support plate 3
Stress impact improves the stability of lifting bracket.
Further, as shown in Figure 8 and Figure 9, multiple gussets are also connected between the first plate body 1 and the second plate body 2
8, multiple gussets 8 surround quadrilateral structure.By the way that multiple gussets 8 are arranged, further increase the bearing capacity of lifting bracket and resist
Impact capacity, safety in utilization are higher.
Optionally, when the area of the second plate body 2 is greater than the area of the first plate body 1, not by the first plate body on the second plate body 2
Reinforcing rib has can be set in 1 part covered, the plate face weldering of the plate face and above-mentioned multiple gussets 8 of the reinforcing rib and the second plate body 2
Connect fixation.As shown in Fig. 9, there are two parallel reinforcements for the part setting not covered by first plate body 1 on the second plate body 2
Muscle.
In the utility model embodiment, the load of support plate 3 is larger, and optionally, support plate 3 is by low-alloy structural steel
At for example, Q390, Q420 etc..This kind of strength of materials and toughness are higher, comprehensive mechanical property with higher after heat treatment, protect
