Abstract
The utility model discloses a structure suitable for shear fork arm frame maintenance. A circular hole (11) is formed in the side face of a sliding way of a base frame assembly (1), the circular hole (11) is right opposite to a shaft (5), a threaded hole (12) is formed in the top, close to the circular hole (11), of the shaft (5), and the shaft (5) can be pulled out from the circular hole (11). The structure suitable for the shear fork arm frame maintenance reduces work loads of an operator and is free of lifting devices, and the maintenance is not limited by the site.
Description
Technical field
The utility model relates to high-altitude operation platform, relates in particular to a kind of structure that yoke is safeguarded of cutting that is suitable for high-altitude operation platform.
Background technology
Existing scissor aerial work platform mainly is comprised of chassis assembly, jib assembly and workplatform assembly, and the jib assembly is arranged on chassis assembly, and workplatform is arranged on the jib assembly.The two ends that the jib assembly is connected with chassis assembly, an end is that fixed end maintains static, the another sliding end of the other end can slide.The sliding end mounting means of existing jib assembly: the jib assembly is connected with axle by nylon slide block with chassis assembly, first axle is bolted on the jib assembly, then nylon slide block is enclosed within on axle, again new jib assembly is pushed along the slideway direction from the rear end of chassis assembly together, finally fixed end is fixed, anchor shaft is directly knocked in the axle sleeve of jib assembly from the outside, with bolt of rear end plate, fixes.Wearing and tearing after the nylon slide block long-term work, corrosion, need to change, and must first fixed end, ladder be dismantled, then the jib assembly is exited to a part along slideway toward the ladder direction, nylon slide block 4 could be removed more to renew.Such maintenance mode operates and quite bothers, and also needs weight-lifting equipment, if work in the wild, is difficult to be safeguarded.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of operating personal workload and alleviates, do not need weight-lifting equipment, safeguards the structure that is suitable for cutting the yoke maintenance that is not subject to regional limits.
In order to solve the problems of the technologies described above, the structure that is suitable for cutting the yoke maintenance that the utility model provides, slideway side opening in described chassis assembly is provided with a circular hole, described circular hole and axle align, the top of closing on described circular hole of described axle is provided with tapped bore, and described axle can be extracted from described circular hole.
Adopt the structure that is suitable for cutting the yoke maintenance of technique scheme, with a screw rod screwed mutually with the tapped bore at axle top, with tapped bore, be connected, with screw rod, from the circular hole of the slideway side of chassis assembly 1, axle is extracted, nylon slide block just can be taken out, and is changed.
Compared with prior art, the utility model has the advantage of:
1, the operating personal workload alleviates;
2, do not need weight-lifting equipment;
3, safeguard and be not subject to regional limits.
In sum, the utility model is that a kind of operating personal workload alleviates, do not need weight-lifting equipment, safeguards the structure that is suitable for cutting the yoke maintenance that is not subject to regional limits.
The accompanying drawing explanation
Fig. 1 is the existing fork mounting structure schematic diagram of cutting.
Fig. 2 is existing sliding end scheme of installation.
Fig. 3 is existing fixed end scheme of installation.
Fig. 4 is improved type sliding end scheme of installation.
Fig. 5 is that improved type is cut fork mounting structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, existing scissor aerial work platform mainly is comprised of chassis assembly 1, jib assembly 2 and workplatform assembly 3, and jib assembly 2 is arranged on chassis assembly 1, and workplatform 3 is arranged on jib assembly 2.The two ends that jib assembly 2 is connected with chassis assembly 1, an end is that fixed end 10 maintains static, the another sliding end 9 of the other end can slide.Have sliding end 9 mounting meanss of jib assembly 2 now as shown in Figure 2: jib assembly 2 is connected with axle 5 by nylon slide block 4 with chassis assembly 1, first axle 5 is fixed on jib assembly 2 by bolt 6, then nylon slide block 4 is enclosed within on axle 5, again new jib assembly 2 is pushed along the slideway direction from the rear end of chassis assembly 1 together, finally fixed end 10 is fixed by Fig. 3, anchor shaft 7 is directly knocked in from the outside in the axle sleeve of jib assembly 2, fixing with bolt of rear end plate 8.Wearing and tearing after nylon slide block 4 long-term works, corrosion, need to change, and must first fixed end, ladder be dismantled, then jib assembly 2 is exited to a part along slideway toward the ladder direction, nylon slide block 4 could be removed more to renew.Such maintenance mode operates and quite bothers, and also needs weight-lifting equipment, if work in the wild, is difficult to be safeguarded.
Referring to Fig. 4 and Fig. 5, be provided with a circular hole 11 at the slideway side opening of chassis assembly 1, circular hole 11 aligns with axle 5, and the top of closing on circular hole 11 of axle 5 is provided with tapped bore 12, and axle 5 can be extracted from circular hole 11.
Referring to Fig. 4 and Fig. 5, first the bolt 6 be fixedly connected with jib assembly 2 on axle 5 is taken off, with a screw rod screwed mutually with the tapped bore 12 at axle 5 tops, with tapped bore 12, be connected again, with screw rod, from the circular hole 11 of the slideway side of chassis assembly 1, axle 5 is extracted, nylon slide block 4 just can be taken out, and is changed.
Claims (1)
1. one kind is suitable for cutting the structure that yoke is safeguarded, it is characterized in that: the slideway side opening in described chassis assembly (1) is provided with a circular hole (11), described circular hole (11) aligns with axle (5), the top of closing on described circular hole (11) of described axle (5) is provided with tapped bore (12), and described axle (5) can be extracted from described circular hole (11).
