Reinforcement cage hoisting mechanism and reinforcement cage conveying line

Abstract

The invention discloses a reinforcement cage hoisting mechanism and a reinforcement cage conveying line. The reinforcement cage hoisting mechanism comprises a cross beam capable of moving up and down, and a reinforcement cage retaining device connected to the cross beam. The lower part of the reinforcement cage retaining device is provided with an open slot capable of at least partially accommodating the reinforcement cage. A first bolt and a second bolt which are inserted into a reinforcement cage and can clamp the reinforcement cage are respectively arranged on two longitudinal sides of the lower part of the open slot. The first bolt and the second bolt can reciprocate in the longitudinal direction and are oppositely arranged or arranged in a staggered mode in the transverse direction. By the adoption of the structure, due to the gravity of the reinforcement cage retaining device and an arc-shaped structure of surfaces of upper reinforcing steel bars on the reinforcement cage, the reinforcement cage is forced to rotate or the reinforcement cage retaining device slides along the surfaces of the upper reinforcing steel bars on the reinforcement cage, then the upper surface of the reinforcement cage is completely contained in the open slot, the reinforcement cage retaining device can conveniently position the reinforcement cage and allow the bolts to be inserted during hoisting, and the cage grabbing reliability is improved; and meanwhile, the bolts are longitudinally and horizontally inserted, so that the reliability of cage grabbing and unhooking is ensured.

Description

technical field [0001] The invention belongs to the technical field of prefabricated component manufacturing equipment, and relates to a tendon cage lifting mechanism and a tendon cage conveying line. Background technique [0002] Precast concrete piles are pile foundation materials widely used in the construction industry, and steel cages are an indispensable part in the production process of precast concrete piles. The steel cages are mainly processed by the combination of main bars and spiral bars or stirrups. It needs to be hoisted and transported to the designated location by a hoisting device, but due to the long length and heavy weight of the steel cage, it is difficult to transport, and the steel cage is usually lifted by a hook. For example, a steel cage lifting device disclosed in the prior art is connected with a hook for transportation at the bottom of the suspension beam, and the hook is turned over under the action of the driving mechanism, stretches into the s...

Problems solved by technology

However, it is found in the actual production process that if the steel cage lifting device of the above structure is adopted, when the steel cage is transported to the hook lifting place and the predetermined position, the steel cage rolls or falls to the predetermined position from the conveying structure, due to Due to inertia, the steel cage continues to move forward, and it will inevitably shake or turn over. At this time, the circumferential position of the main reinforcement of the reinforcement cage changes relative to the ideal predetermined position, and it cannot be guaranteed that the hook must be between the two main reinforcements. , the position of the hook needs to be adjusted to a certain extent to be able to effectively lift the reinforcement cage, and it is very likely that the hook cannot be unhooked when unhooked
