Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 , figure 2 As shown, a portable hoist consists of three parts: a hoisting mechanism (cracker 9, gear 6, gear shaft, reel 8), a locking mechanism (hook 3), and a steel structure bracket (bracket 1 and rotation mechanism 2). .

[0017] It includes a bracket 1, a steel frame 8, a gear shaft and a rocker 9; the bracket 1 includes two ladder-shaped frames with a plurality of beams, and the upper ends of the two ladder-shaped frames are hinged together by a rotating mechanism 2 (here referred to as a hinge). The steel frame 8 is movably arranged on the support 1, and the steel frame 8 has a rectangular structure, and the lower end of the steel frame 8 has a slot for snapping into two parallel beams of the ladder frame to realize flexible connection. There are two live gear shafts, and each gear shaft is installed on the steel frame...

Abstract

The invention relates to a portable hoister, which comprises a bracket, a steel frame, two gear shafts and rocking handles, wherein the steel frame is movably or fixedly arranged on the bracket; each gear shaft is arranged on the steel frame through at least two bearings; the two gear shafts are parallel to each other; the two gear shafts are provided with a gear respectively; the diameters of the two gears are different, and the two gears are engaged with each other; a winding drum is arranged on one of the gear shafts; and the rocking handles are connected with two ends of the two gear shafts. By the portable hoister, the labor intensity of a farmer in processes of putting a submersible pump into a well and taking the submersible pump out of the well can be reduced, and the automation degree and the production efficiency of agricultural production can be improved.

Description

technical field [0001] The invention relates to a portable hoist and belongs to the technical field of equipment manufacturing of agricultural machinery. Background technique [0002] In modern life, with the improvement of farmers' living standards, the demand for agricultural machinery is increasing; people urgently need a portable hoist that is light, low-cost, and easy to operate. In rural areas in the north, farmland needs to be irrigated every year. Infrastructure such as water wells has been built and applied on a large scale. But the process of putting the submersible pump into the well and proposing from the well is manually operated. Farmers have high labor intensity and low production efficiency, which affects the automation level of agricultural production. Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned deficiencies in the prior art, provide a kind of portable lifting machine, it can reduce the labor in...
