Abstract

The utility model discloses a well ring hoisting device, belongs to the technical field of building construction machinery, and solves the technical problem that a traditional lifting appliance is easy to slip and damaged by local stress due to the fact that a preset lifting point does not exist in a concrete inspection well ring. The technical scheme is characterized in that a hanging barrel is placed in a well ring, a plurality of supporting rods which are uniformly distributed in the circumferential direction are horizontally moved through barrel wall supporting holes, the tail ends of the supporting rods are inserted into the step bottom of the inner wall of the well ring or the edge of the bottom of the well ring to achieve lifting, a horizontal first limiting plate is arranged on a barrel bottom plate at the bottom of the hanging barrel, the inner end limit of the supporting rods is positioned between the barrel bottom plate and the first limiting plate, and the lower pressure of the first limiting plate forces the supporting rods to keep a horizontal stable state when the well ring is lifted. The device is used for safely hoisting the well ring of the concrete inspection well, obviously reduces the risk of well ring breakage, effectively eliminates the potential slipping hazard, and improves the installation efficiency and the positioning accuracy.

Description

Well ring hoisting device Technical Field The utility model relates to the technical field of building construction, in particular to a well ring hoisting device. Background The lifting of the well ring of the concrete inspection well depends on manual transportation or a general lifting appliance for a long time. During manual transportation, the well ring is heavy in weight and heavy in size, and edges are easy to collide by multiple people to damage, so that the damage rate is high, the tightness is affected, and the cost is increased. When the universal lifting appliance (such as a steel wire rope and a lifting hook) is adopted, the suitability of the lifting appliance is poor because the well ring is of an annular structure without a preset lifting point, the steel wire rope is easy to slip, the hanging hook is easy to cause local stress concentration cracking, meanwhile, the lifting and positioning are inaccurate, repeated adjustment is needed, and the single installation time is more than 20 minutes. The root of the problem is that the well ring has no special stress point, and the structural characteristics of the well ring are difficult to match in a traditional mode. The development of the special tool has the problems that the external clamping device is easy to damage the well ring and needs accurate size adaptation, and the internal supporting device needs to solve the technical difficulties of multi-point multi-directional synchronous stress, reliability under vibration and the like in a narrow space. The field is lack of a hoisting scheme with high efficiency and low loss, and construction quality and efficiency are restricted. Disclosure of utility model The utility model provides a well ring hoisting device, which can solve the problems that a general hoisting tool (such as a steel wire rope and a hoisting hook) cannot be reliably gripped due to the special form of an annular structure when a concrete well ring without a preset hoisting point is hoisted, and the well ring is easy to slip or damage due to local stress concentration.
