The utility model is characterized in that the left and the right sides of a cylinder end are connected with cylinder pins, and the upper part of the cylinder end is connected with a device for pulling out arm pins, near which a detecting switch for detecting the ending position and the starting position of the device for pulling out arm pins is arranged; the lower ends of the left and the right cylinder pins are provided with ending position and starting position detecting proximity switches; the proximity switches for detecting the positions of the telescopic arms are arranged on both sides of each of the rear ends of the telescopic arms, and upper parts of the rear ends of the telescopic arms are connected with arm pins; both sides of each of the cylinder end and a cylinder are provided with floating telescopic cylinder slide ways, and chutes at the left and the right positions on the rear end of each section of booms. The utility model has the advantages that the structure is simple; the differences among the sections of the booms are small; the load-lifting capability and the universality are high; each section of the booms can be telescopic independently, so multiple booms can be combined to use by a user conveniently at will; the weight of the utility model is light, so the utility model is more suitable for being used on a large-tonnage crane.
Description
Technical field
The utility model relates to a kind of hoisting crane control telescopic boom retractor device, particularly a kind of wireless control retractor device.
Background technology
At present, the telescopic boom of car hosit is a tubular structure, telescopic boom flexible adds steel rope by oil cylinder and arranges and realize, multi-stage telescopic arms is sleeved on together in proper order, rear portion at basic arm is connected with hydraulic cylinder piston rod by bearing pin, hydraulic actuating cylinder is by piston rod, cylinder head, cylinder barrel constitutes, cylinder head and cylinder barrel welding, pass through a left side at cylinder head, right axle shaft and two joint arms link together, rearward end at cylinder barrel is connected with roller, steel rope links together by roller and three joint arm rear ends, the other end is connected with the rear end of basic arm, and it is overhanging synchronously to stretch out the control telescopic boom by oil cylinder, and an end of another steel rope is connected the head of basic arm, the other end is connected with three joint arm rear ends by the roller of the rear end of two joint arms, and the oil cylinder retraction drives the synchronous retraction that respectively saves arm.This telescopic boom device causes the design section between telescopic boom to differ greatly because of arranging steel rope row structure, the stretching structure complexity, and arm weight is big, and stiffness is little, influences the lift heavy ability.
Summary of the invention
The purpose of this utility model is to provide the cross section between a kind of telescopic boom to differ little, and arm is in light weight, the wireless control retractor device that the lift heavy ability is big.
The purpose of this utility model is achieved in that on left and right two limits of cylinder head and is connected with the cylinder pin, cylinder head top is connected with arm pin extracting apparatus, near arm pin extracting apparatus, have and detect its detector switch of beginning position eventually, the position probing that begins is eventually arranged near switch in left and right cylinder pin lower end, each arm position probing is arranged near switch in the rear end of each telescopic boom two sides, the telescopic boom upper rear end is connected with the arm pin, cylinder head and cylinder barrel two sides are provided with unsteady telescopic oil cylinder slideway, position, the left and right sides, the rear end chute of each joint arm.
Beneficial effect: owing to adopt such scheme, saved the rope arranging device, actv. has increased the arm sectional area, sectional area between adjacent arm is more or less the same, has improved the bulk strength of crane arm greatly, in light weight, the lift heavy ability is strengthened greatly, has reached the purpose of this utility model.This retractor device is simple in structure, and the cross section between arm differs little, lift heavy ability and highly versatile, and each joint arm can stretch separately, makes things convenient for the user that more piece arm combination in any is used, and this installation weight is light, is more suitable for using on hoister in large tonnage.
