Description

Technical Field

[0001] This invention belongs to the field of hoisting technology, and in particular relates to a ladder-type hoisting machine for lifting photovoltaic panels. Background Technology

[0002] As is well known, photovoltaic (PV) panels are a common technology for converting solar energy into electrical energy. To enable households to use the electricity generated by PV panels to meet their daily electricity needs, most PV panels are installed side by side on rooftop supports. However, PV panels are relatively large and heavy, and it is laborious, time-consuming, and unsafe to pull them from the ground to the roof by hand. Therefore, the following invention was developed. Summary of the Invention

[0003] The invention provides a ladder-type hoist that is quick to assemble and easy to use. This machine consists of a ladder-shaped slide frame and a trolley that slides up and down the slide frame. The trolley is a rectangular frame with four flat wheels and four grooved wheels in the longitudinal and transverse directions, and the lower plate of the frame is equipped with an upward-facing fork. In use, the photovoltaic panel is placed on the trolley and will not slide down under the action of the fork. When the free end of the electric hoist at the bottom passes over the fixed pulley at the top and combines with the trolley frame to form a linkage, the manual electric hoist trolley will lift the photovoltaic panel to the roof.

[0004] The technical solution to the technical problem is as follows: The slide frame is composed of two identical outer slide tubes. The outer slide tube is a rectangular steel pipe of a certain length and model, with the narrow side as the top and bottom. Angle iron of equal length is used to fasten it to the wide side, so that one side is flush with the top and welded together to form an outer slide tube. Two identical outer slide tubes form a slide frame section. The whole machine requires at least two slide frames, and each slide frame section is not necessarily of equal height. The outer slide tube of every two slide frames is made by inserting an inner sleeve that is more than half the height of the two outer slide tube sections into the two outer slide tube sections to make the insertion depth equal. An appropriate length of channel steel or square tube is added in the middle of the inner sleeve for reinforcement. The crossbeam includes three types: base crossbeam, top crossbeam, and crossbeams of each section. The base crossarm has T-shaped ends, with the T-shaped ends using the same type of inner sleeve. The crossarm supports are square tubes for easy installation of the electric hoist. The top crossarm also uses the same type of inner sleeve at both ends, and its crossarm is perpendicular to the inner sleeves at both ends, with its fixed pulley located in the middle of the top crossarm. Each crossarm section is composed of a sleeve joint, a sleeve crossarm, and a tie rod. Each crossarm section is first assembled by welding the sleeve joints to the middle and upper parts of the outer slide tube, then using tie rods to align the sleeve joints with the same type of crossarm sleeve one-to-one, fixing each slide frame into a single unit. The number of sections can be determined according to actual needs. Assembly is done section by section from bottom to top on the ground according to the required height. After the top is sealed, the ladder is placed against the roof, the wire rope is wound, and the electric hoist is operated manually. This achieves the design objective. Beneficial effects: quick assembly and disassembly, convenient use, labor-saving and efficient, and strong safety.

[0005] A ladder-type hoist includes: an outer slide pipe; an inner sleeve; a slide frame; a trolley; a base crossbeam; a top crossbeam; and various crossbeam sections. Its features are: the outer slide pipe is a rectangular steel pipe with its narrow side as the top and bottom surfaces, welded to the wide surface with angle irons of equal length, making one side flush with the top; the inner sleeve is longer than half the length of the outer slide pipe, and a channel steel or square tube of appropriate length is added inside the middle of the inner sleeve; the slide frame consists of two identical outer slide pipes with the angle iron slide facing inwards; the trolley has four right-angle grooved wheels on the left and right sides along the horizontal direction below the front and rear of its rectangular frame, capable of sliding up and down along the angle iron slide, and also having four right-angle grooved wheels on the front and rear sides. Four flat wheels are provided on the side, which can slide up and down simultaneously along the upper plane of the outer slide tube. An upward-facing fork is welded to the bottom of the trolley chassis. The two ends of the base crossarm are T-shaped, and the T-tail is an inner sleeve of the same model as the former. The electric hoist is fixed to the crossarm bracing. The two ends of the top crossarm are also inner sleeves, which are perpendicular to the inner sleeves. The fixed pulley is located in the middle of the crossarm. Each section of the crossarm is composed of a sleeve joint, a sleeve crossarm, and a pull rod. The sleeve joint is first welded to the middle and upper parts of the outer slide tube, and then the outer sleeve crossarm of the same model is fixed one-to-one with the pull rod to fix the slide frame of each section into a whole.

[0006] Specific implementation method

[0007] The electric hoist is fixed to the 40-square tube crossarm of the base. During assembly, first insert the two outer slide tubes of the lowest slide frame into the inner sleeves on the left and right sides of the base crossarm, and secure them with tie rods to form a fixed slide frame. Let the pulley slide in from the top and down to the bottom. Then insert the inner sleeves into the two outer slide tubes; insert the two outer slide tubes of the second section into the inner sleeves on the left and right sides. Repeat this process for the other slide frames. Once the desired height is reached, seal the top with the top crossarm. The electric hoist's wire rope runs from the bottom of each crossarm upwards, around the fixed pulley at the top, and then connects with the pulley on the top of each crossarm to form a linkage. Lift the ladder frame and lean it against the building, then manually operate the electric hoist to begin operation.
