Embodiment Construction

[0022] Such as figure 1 As shown, a small lifting device consists of an upper lifting structure, a braking system, and a lower support structure. The upper lifting structure is made up of: rocking handle 3, rotating shaft 4, reel 5, baffle plate 6, winding rope 7, suspension hook 8, the closed ring 9 of anti-decoupling. The brake system is made up of: brake band 10, brake pedal 11. The lower supporting structure is composed of: a bracket 1 and a ball bearing 2. Ball bearings are finished components, mainly composed of four basic elements: balls, inner rings, outer rings and retainers.

[0023] The ball bearing 2 is fixed on the bracket 1, the rotating shaft 4 passes through the ball bearing 2 and is welded and fixed with the rocker 3, the drum 5 is supported by steel bars and welded with the rotating shaft 4, and the drum 5 is connected with the winding rope 7, the hook 8 and the closed ring 9 Used in combination to form an upper lifting structure.

[0024] Bracket 1 is we...

Abstract

The invention discloses a small hoisting device. The small hoisting device comprises a bracket; a ball bearing is fixedly arranged on the bracket; a rotating shaft is mounted on the ball bearing; one end of the rotating shaft is fixedly connected with a rocking rod; a drum is fixedly mounted on the rotating shaft, and is provided with a winding rope; and the tail end of the winding rope is connected with a lifting hook. One end of a brake belt is fixedly connected with the bracket through double ring buckles; the other end of the brake belt bypasses through the drum to be fixedly connected to the bracket; the bracket is connected with a brake pedal; and the brake pedal abuts against the brake belt. The small hoisting device solves the problems of low efficiency and potential safety hazards in traditional pure manual construction, and eliminates the problems of high investment and no economy in combined construction of a tower frame and an electric windlass.

Description

technical field [0001] The invention is a small lifting device, which is suitable for the construction of manual excavation piles with small diameter and shallow excavation depth of the bridge substructure. Background technique [0002] Manually digging holes for the pile foundation of the lower part of the bridge is an important process in bridge construction. Generally, the lifting and slag removal is realized by traditional manual lifting or the combination of electric hoist and lifting tower. The construction efficiency of manual lifting is low, and the hands are also seriously damaged, so the safety cannot be guaranteed; the combination of the tower and the hoist has a large single lifting capacity, which is suitable for manual excavation of pile holes with large diameter and deep excavation, but the task of erecting the tower Heavy, inconvenient to move, large demolition workload, more steel pipes and fasteners are required, so it is no longer economical and applicabl...
