Embodiment Construction

[0024] Such as Figure 1-7 The hoisting device shown includes a boom mounting base 2, a lifting ring 1, a sliding block 4, two booms 7 and a self-locking mechanism. Three or more booms can be used according to site conditions. The boom mounting seat 2 in this embodiment is mainly composed of a U-shaped beam 16, one side of the bottom plate of the U-shaped beam 16 is fixed with a lifting ring mounting seat 19, and the other side is fixed with a guide rod 17 coaxial with the lifting ring mounting seat 19. , The side plate of the U-shaped beam 16 is also provided with a connecting rod hinge bracket 18 . The above-mentioned suspension ring 1 is fixed on the suspension ring mounting seat 19, and the above-mentioned sliding block 4 is sleeved on the guide rod 17 through the through hole of the sliding sleeve 15 on the sliding block 4 to complete the sliding of the sliding block 4 along the axis of the guide rod 17. The guide rod 17 can also be provided with a groove, the sliding s...

Abstract

The invention discloses a hoisting apparatus. The hoisting apparatus comprises an arm installation seat, a guide bar, a sliding block arranged on the guide bar in a sliding manner, and a self-locking mechanism, the self-locking mechanism is mainly composed of a first connecting rod, a second connecting rod and a stop block, the first connecting rod is hinged to the second connecting rod to form a middle hinge point, the other end of the first connecting rod is hinged to the arm installation seat to form a first hinge point, and the other end of the second connecting rod is hinged to the sliding block to form a second hinge point; and when the hoisting apparatus is in a close state, the middle hinge point is positioned in the excessively rigid point position offsetting the first and second hinge points, and the stop block is in stopping cooperation with the first connecting rod or the second connecting rod behind the excessively rigid point of the middle hinge point. The self-locking mechanism is simple to operate, ensures that the close state of the hoisting apparatus is locked before hoisting, and avoids the hidden safety troubles of claw hook opening, hoisting loosening and hoisted member shedding caused by the shake of a hoisting rope after the hoisting.

Description

technical field [0001] The invention relates to a hoisting device. Background technique [0002] The ceramic bottle of the outdoor high-voltage circuit breaker needs to be hoisted with a sling when it is assembled. The single pole of the product composed of upper and lower porcelain bottles, upper and lower terminal boards and other components also needs to be hoisted again after the assembly is completed, and a single porcelain bottle (126kV) weighs about 100kg. , the weight of the product (126kV) single pole is about 350kg. The commonly used lifting device is to directly use the lifting rope with the hook to directly hook the mounting hole on the flange of the porcelain bottle for lifting. The usual lifting position is the installation of the upper terminal board. Holes, for these heavy porcelain bottles, it is obviously unreasonable to use only two installation holes for hoisting. [0003] In the Chinese patent document CN103434924A, a hoisting device is disclosed, which...
