Abstract
The utility model discloses a power assembling and disassembling pin device for a crane. The bottom part of a cylinder barrel of an oil cylinder (7) is provided with a connection block (1) capable of screwing in a pin, a piston rod of the oil cylinder (7) is connected with the upper end of a barrel, and the lower end of the barrel is provided with boss clubs (4). Both sides of a pin hole are axially and symmetrically provided with card boards (3), and the boss clubs (4) can be screwed into the card boards (3). The barrel is formed by abutting joint of a long barrel (6) and a short barrel (5), and the long barrel (6) and the short barrel (5) are all provided with the boss clubs (4) which can be screwed into the card boards (3). The power assembling and disassembling pin device for the crane is used for assembling and disassembling variable amplitude pins and main arm pins and protecting pin rolls against damage and has the advantages of low labor intensity, high efficiency and high popularity.
Description
Technical field
The utility model relates to a kind of dismounting pin assembly, particularly relates to a kind of crane power dismounting pin assembly.
Background technology
Along with the direction of autocrane to large-tonnage, super-tonnage develops, the external diameter of crane, weight also can be increasing, and require not conform to for human oriented design, and is unbecoming with other configuration.Present stage, the principal arm pin and the luffing pin of autocrane were to adopt hammer to knock to carry out demolition, installation, and this traditional manual dismounting mode has following shortcoming: (1) manual dismounting is wasted time and energy, and labour intensity is big, efficient is low; (2) pin roll end face has the hammer trace, influences presentation quality.
The utility model content
The labour intensity that technical problem to be solved in the utility model provides a kind of dismounting luffing pin, principal arm pin is low, efficient height, versatility height, the crane that the protection bearing pin is not damaged power dismounting pin assembly.
In order to solve the problems of the technologies described above, the crane that the utility model provides power dismounting pin assembly, the cylinder barrel bottom of oil cylinder is provided with the contiguous block that can screw in pin, the piston rod of described oil cylinder is connected with the cylinder upper end, described cylinder lower end is provided with boss, the pin-and-hole both sides axially are arranged with clamp, and described boss can be screwed in the described clamp.
Described cylinder is combined by long cylinder and short cylinder butt joint, and described long cylinder and short cylinder are equipped with the boss that can be screwed in the described clamp.
The crane that adopts technique scheme as support, screws in the cylinder lower end in the clamp earlier with cylinder with power dismounting pin assembly, oil cylinder is attached thereto again, and device provides power by the expansion interface of vehicle-mounted hydraulic system to oil cylinder.This device integrates and plugs and unplugs the bearing pin function, utilizes vehicle-mounted power, stable drive, and compact conformation, versatility is better, takes into account plug luffing pin, principal arm pin.
In sum, the utility model is that the labour intensity of a kind of dismounting luffing pin, principal arm pin is low, efficient height, versatility height, the crane that the protection bearing pin is not damaged power dismounting pin assembly.
Description of drawings
Fig. 1 is for pulling out the state diagram of luffing pin;
Fig. 2 is for pulling out the state diagram of principal arm pin.
The specific embodiment
Referring to Fig. 1, the welding of the cylinder barrel of oil cylinder 7 bottom is provided with the contiguous block 1 that can screw in luffing pin 2, and the piston rod of oil cylinder 7 is connected with long cylinder 6 upper ends, and short cylinder 5 lower ends are provided with boss 4, and the pin-and-hole both sides axially are arranged with clamp 3, and boss 4 can be screwed in the clamp 3.
Referring to Fig. 1, oil cylinder 7 has oil inlet and outlet and contiguous block 1, contiguous block 1 is welded in oil cylinder 7 cylinder barrels bottom, passive long cylinder 6 has opened for 1/4 lack, the connection of convenient turnover oil pipe, must connect short cylinder 5 when plugging and unplugging the luffing pin, the boss 4 of long and short cylinder lower end all can screw in the clamp 3, and clamp 3 is symmetrically welded at the pin-and-hole both sides.
As shown in Figure 2, during dismounting principal arm pin 8, earlier oil cylinder 7 bottom contiguous blocks 1 are screwed in the principal arm pin 8, the boss 4 with long cylinder 6 lower ends screws in the clamp 3 again, oil cylinder 7 oil inlet and outlets are connected with the expansion interface of vehicle-mounted hydraulic system, after utilize the cylinder bar of oil cylinder 7 to stretch to drive the dismounting of principal arm pin 8.When dismounting pin luffing pin 2, just connect short cylinder 5 and get final product, as shown in Figure 1 in long cylinder 6 lower ends.
In order to improve its versatility, there are two as the cylinder that supports, be used for pulling out principal arm pin 8 when only doing to support with long cylinder 6, long cylinder 6, short cylinder 5 combinations are used for pulling out luffing pin 2 when doing to support.
This device integrates and plugs and unplugs the bearing pin function, utilizes vehicle-mounted power, stable drive, and compact conformation, versatility is better, takes into account plug luffing pin, principal arm pin.
Claims (2)
1, a kind of crane power dismounting pin assembly, it is characterized in that: the cylinder barrel bottom of oil cylinder (7) is provided with the contiguous block (1) that can screw in pin, the piston rod of described oil cylinder (7) is connected with the cylinder upper end, described cylinder lower end is provided with boss (4), the pin-and-hole both sides axially are arranged with clamp (3), and described boss (4) can be screwed in the described clamp (3).
2, crane according to claim 1 power dismounting pin assembly, it is characterized in that: described cylinder is combined by long cylinder (6) and short cylinder (5) butt joint, and described long cylinder (6) and short cylinder (5) are equipped with the boss (4) that can be screwed in the described clamp (3).
