Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building engineering, and particularly relates to a material lifting device for house building. BACKGROUND

[0002] In the house building industry, material transportation is one of the key links in the construction process. Especially in high-rise building construction, the transportation demand of non-blocky powdery and granular materials such as sand, cement and bricks is particularly urgent, especially in the construction process of high-rise buildings, a large amount of building materials such as sand, cement, steel bars and prefabricated boards need to be transported to different floors. The traditional material transportation method often relies on manual carrying or the use of simple hoisting equipment, but these methods have problems such as low efficiency, great safety hazards and high cost, so it is necessary to use stable building frames to lift the materials.

[0003] At present, the building frame used in transportation usually has a steel wire rope between the building frame and the transportation frame containing materials, which forms a safety protection for the transportation frame, so that when the transportation frame or the lifting equipment of the transportation frame is damaged or broken, the steel wire rope can protect the transportation frame, thereby avoiding accidents (such as rope breakage, loose fixing point, etc.) during transportation. As a safety rope, the steel wire rope can quickly play a role to prevent building materials and transportation equipment from falling and protect the safety of on-site personnel. However, the outer surface of the steel wire rope is easily attacked by moisture, oxygen and various corrosive substances in the air for a long time, which causes the oxidation and rusting process. This oxidation not only gradually weakens the tensile strength of the steel wire rope, but also may increase the surface roughness, thereby affecting the effective connection and sliding performance with the hoisting equipment. If effective rust prevention and maintenance measures are not taken in time, the service life of the steel wire rope will be greatly shortened, and even may break at a critical moment, causing serious safety accidents.

[0033] The working principle of the building material lifting equipment is as follows:

[0034] In use, when the ladder frame 2 transports building materials, first, the lifting motor 61 is started, the lifting motor 61 drives the third gear 62 to rotate, the third gear 62 moves along the rack 63 on one side of the ladder frame 2, at this time, the whole material rack 3 can be driven to move and transport building materials, and at the same time, the driving motor 42 is started synchronously when the lifting motor 61 is used, the safety rope 44 is operated by the driving motor 42, so as to realize the protection of the material rack 3, and the safety rope 44 can prevent the material rack 3 from loosening and falling off, thereby avoiding danger.

[0035] Further, when the safety rope 44 is installed and used, the spiral groove arranged on the surface of the spiral roller 54 can limit the safety rope 44, so that the safety rope 44 can be arranged and wound on the outer surface of the take-up roller 43 in an orderly manner, the take-up process is optimized, the time and labor required for manually arranging the safety rope 44 are reduced, the electric push rod 557 is started, the electric push rod 557 can drive the piston 556 to move, the lubricating oil stored in the spiral roller 54 is pressurized by the piston 556, at this time, the lubricating oil slowly flows out through the oil immersion hole 554 on the outer surface of the spiral roller 54, and the lubricating oil can be continuously applied to the surface of the safety rope 44 and the take-up roller 43, so that a uniform lubricating film is formed between the safety rope 44 and the take-up roller 43, the direct friction between the two is greatly reduced, the heat and wear caused by friction are reduced, and the service life of the safety rope 44 and the take-up roller 43 is significantly prolonged.

[0036] Further, when the safety rope 44 is used, the safety rope 44 moves through the fixed pulley one 45 and the fixed pulley two 466. During the material transportation process, sudden acceleration, deceleration or jolt may occur. The fixed pulley two 466 can buffer these impacts to a certain extent and reduce damage to the safety rope 44.
