Problems solved by technology

However, it is difficult to compact the backfill earthwork in some corner areas. The existing backfill earthwork uses many types of mechanical equipment with a single purpose, which requires a large amount of mechanical equipment and a lot of manpower, which cannot meet the existing construction needs.

Abstract

An automatic unhooking sling comprises two main hooks. An auxiliary hook located between the two main hooks is hinged to an auxiliary hook shaft. The upper end of the auxiliary hook is provided with a contact, and the lower end of the auxiliary hook is provided with a hook tip portion upwards extending out of the inner edges of the main hooks. The upper portion of each main hook is provided with a sliding fastener mechanism corresponding to the contact. Each sliding fastener mechanism comprises a U-shaped shell and a control lever, wherein the inner wall of the U-shaped shell is provided with a longitudinal guide groove, a lever shaft is arranged outside the U-shaped shell, a sliding fastener making contact with the contact is arranged in the guide groove in a sliding mode, a limit pin corresponding to the sliding fastener is arranged in the guide groove, the sliding fastener is composed of a sliding portion and a guide shaft longitudinally fixed to the sliding portion, and the guide shaft is connected with one end of the control lever through a reset spring. The automatic unhooking sling is simple in structure, is connected with a mechanical power arm when used, and is easy and convenient to operate, capable of saving time and labor, safe and reliable, the depth of primary backfill earth is large, punning can be achieved, the punning operating speed can be increased greatly, construction efficiency is improved, and the construction quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of hoisting tools, in particular to an automatic decoupling hoist. Background technique [0002] At present, in large-scale factory construction projects, residential public buildings and civil engineering construction of larger buildings, structures, railways, highways, etc., it is usually necessary to carry out a large amount of earthwork backfilling work, and the backfilling thickness is 200~350mm per layer. Carry out construction; for deeper backfill earthwork, it is often necessary to use heavy hammer dynamic compaction method to repeat the steps of layered backfill, compaction, sampling, inspection, and backfill. [0003] The heavy hammer dynamic compaction method is an effective method for foundation soil reinforcement. Due to the constraints of mechanical equipment and site factors, this method is not suitable for construction in complex and narrow sites; The device and the power device are softly c...
