Description

Lifting device for auxiliary installation anchor bolt

Technical Field

The utility model belongs to the technical field of fan foundation installation, and particularly relates to a lifting device for auxiliary installation of an anchor bolt.

Background

The anchor bolt type foundation is a structural form widely adopted by the land foundation of the wind generating set. Compared with a foundation ring type foundation, the anchor bolt type foundation is more reasonable in stress. Since the anchor assembly in an anchor-type foundation looks like a birdcage, the anchor assembly is also referred to as an anchor cage. For example, the publication number CN109595126a discloses a foundation anchor bolt assembly of a wind generating set and a construction method for connecting a tower tube thereof, the anchor bolt assembly comprises an upper anchor plate, a lower anchor plate, a plurality of anchor bolts, a supporting sleeve group and a protecting sleeve, the anchor bolts are connected with the upper anchor plate and the lower anchor plate, the supporting sleeve group comprises a first supporting tube, a second supporting tube and a connecting tube fixedly connected with the first supporting tube and the second supporting tube, the first supporting tube and the second supporting tube are respectively sleeved on two adjacent anchor bolts, the first supporting tube and the second supporting tube support the upper anchor plate, and the protecting sleeve is sleeved on the rest anchor bolts. The anchor bolt assembly is required to be installed on a fan foundation after pouring solidification is completed, and the anchor bolt is connected with a bolt on the fan foundation through a nut so as to ensure the stability of the fan. However, when installing the crab-bolt subassembly at present, need the manual work lift up the crab-bolt subassembly just can be in the same place the bolted connection of crab-bolt and fixing on the fan basis, and the outside sheath that has all cup jointed of crab-bolt can lead to the workman to lift up the atress difficulty when the crab-bolt subassembly. Therefore, a lifting device for assisting in installing an anchor bolt is urgently needed, the anchor bolt assembly is assisted to be installed, and when the anchor bolt assembly is installed, the anchor bolt is lifted by using the lifting device, and then the anchor bolt can be quickly and fixedly connected with the bolt.

Disclosure of Invention

The utility model aims to provide a lifting device for assisting in installing an anchor bolt so as to solve the problem of difficult installation of the anchor bolt assembly.

The lifting device for auxiliary installation anchor bolt in this scheme, including the lifting rod, the lifting rod bottom is connected with the lifting ring through pivot horizontal rotation, lifting rod top fixedly connected with handle, lifting ring bottom fixedly connected with torsional spring, torsional spring and lifting rod fixed connection, lifting rod and lifting ring junction are equipped with the baffle, baffle fixed connection is on the lifting rod, and is perpendicular with the lifting rod.

The working principle of the scheme is as follows: when the anchor bolt is required to be installed, the lifting ring is vertically rotated to be sleeved at the bottom of the anchor bolt, the lifting ring is vertical to the lifting rod, the lifting handle drives the anchor bolt to move upwards, after the anchor bolt is slightly far away from a bolt on the fan foundation, a nut on the anchor bolt is connected with a bolt thread on the fan foundation, after the anchor bolt is installed, the lifting ring is taken down from the anchor bolt, a torsion spring is installed between the lifting rod and the lifting ring, the lifting ring can automatically rebound to the outer wall of the lifting ring due to the resilience force of the torsion spring when the lifting ring is not used, the lifting ring is changed into a state vertical to the lifting rod, a baffle plate is fixedly connected to the lifting plate, the rotating angle of the lifting ring can be limited, the baffle plate is vertical to the lifting plate, and the lifting ring can be rotated to stop rotating when the lifting rod is vertical.

The beneficial effects are that: when using this device auxiliary installation crab-bolt, can lift the crab-bolt fast to supplementary crab-bolt is installed on the fan foundation, can effectively improve installation effectiveness, and fixed connection torsional spring between lifting rod and lifting ring, makes the lifting ring when not using, and automatic resilience can avoid the lifting ring always perpendicular with the lifting rod, easily stabs the condition of staff, and baffle restriction lifting ring's turned angle is 90 degrees only, avoids lifting ring to rotate excessively and can not reach the promotion effect.

Further, the lifting rod is rotationally connected with a clamping block which is clamped with the lifting rod. When not using the lifting ring, the lifting ring is rebounded to be parallel to the lifting rod, and the clamping block is rotated to be perpendicular to the ground, so that the clamping block is clamped with the lifting ring, the lifting ring is fixed, the defect that the supporting force of the torsion spring is insufficient is avoided, and the lifting ring can still rotate downwards.

Further, electric telescopic rods are fixedly connected to the bottoms of the lifting rods. When the lifting ring is sleeved at the bottom of the anchor bolt, the electric telescopic rod can be extended, so that the anchor bolt can be driven to lift, and the effect of auxiliary installation is achieved.

Further, the electric telescopic rod is connected with a controller through a circuit, and the controller is arranged on the handle. When the anchor bolt is installed, the controller can control the telescopic length of the electric telescopic rod, so that the installation is more labor-saving, the controller is installed on the handle, only one worker can install the electric telescopic rod, the workload of the worker can be reduced, and the installation efficiency is increased.

Further, the torsion spring comprises a spring and two hook-shaped rotating arms, the two hook-shaped rotating arms and the spring are integrally formed, one hook-shaped rotating arm is arranged at the bottom of the lifting ring, and the other hook-shaped rotating arm is arranged on the lifting rod. The torsion spring is arranged between the lifting ring and the lifting rod through the hook-shaped rotating arm, so that the torsion spring is more stable.

Further, the handle is a cylindrical straight rod and is perpendicular to the lifting rod. The handle is a cylindrical straight rod, so that a worker can better use force when lifting, and the installation is more convenient.

Further, the top of the lifting ring is provided with a rubber pad. The rubber pad is arranged at the top of the lifting ring, so that the lifting ring can be prevented from being directly contacted with the anchor bolt, and the anchor bolt is prevented from being damaged when the stress of the direct contact of the anchor bolt and the lifting ring is overlarge.
