Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples, and it is to be understood that the described examples are only a part of the present invention, and not all of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Example 1 a lowering device for a CFG pile cage as shown in figure 1 comprises a machine platform 1 on which a frame 2 is mounted, a lifting device 3, the lifting device 3 being connected to a vibration device 5 by means of the frame 2, the vibration device 5 comprising a vibration motor 51 and a frame 52 housing the vibration motor.
In order to save the construction time, the lowering device is fixed on a CFG pile machine, the front pile is moved to the next pile drilling process after the concrete pouring of the front pile is finished, and meanwhile, the lowering device is used for installing a reinforcement cage of the first pile. First, the vibration device 5 is lifted to a certain height by the rope 31 and the pulley block, and the mechanical platform 1 is provided with the driving device 4, and the driving device 4 is a winch. One end of the pull rope 31 is collected on the winch 4, and the other end is connected to the bracket 2 through a fixed pulley 32 positioned on the bracket 2 and a movable pulley 33 connected with the vibration device 5. Wherein, one end of the pull rope 31 positioned at the two sides of the movable pulley 33 is connected with the fixed pulley 32; the other end is fixedly connected with the bracket 2, and the bottom of the movable pulley 33 is connected with the vibrating device 5 through a hook. The pulley block can save labor and change the force application direction. The fixed pulley 32 changes the direction of the force applied to the vibration device 5; the movable pulley 33 has a labor-saving effect, and the service lives of the winch 4 and the pull rope 31 are prolonged, so that the cost is saved.
The hoist 4 is started, the pull rope 31 is collected, and therefore the vibration device 5 is lifted, and the vibration device 5 can swing and shake due to the fact that the vibration device is not fixed in the operation process, so that construction efficiency is affected. Therefore, the elevating stabilizer 54 is mounted on the frame 52, and the elevating stabilizer 54 includes two holding plates 541 disposed obliquely. The movement of the vibration means 5 on the support 2 is controlled by the contact sliding of the clamping plate 541 along the support 2. As shown in fig. 2, fig. 2 is a schematic view of the clamping plates 541, and the distance between the clamping plates 541 increases gradually in a direction approaching the bracket 2, so that the sliding position of the vibration device 5 is limited, and the vibration device is prevented from shaking left and right to affect the construction efficiency.
After the frame 52 is lifted, in order to facilitate connection between the reinforcement cage and the frame 52, a cylindrical fixer 53 is installed at the bottom of the frame 52, the reinforcement at one end of the reinforcement cage is simply bent towards the direction close to the center of the reinforcement cage, the reinforcement cage is erected and directly sleeved into the cylindrical fixer 53, and the reinforcement cage is installed; when the vibration motor 51 is started, the bracket 2 connected to the vibration device 5 is also forced to vibrate. In order to reinforce the stability of support 2, two bracing pieces 6 that the slope set up on mechanical platform 1 are connected to support 2 one side, and bracing piece 6 constitutes the triangular supports system with support 2, has strengthened support 2's steadiness. Vibrating device 5 relies on self gravity to move down, and the other end of steel reinforcement cage embolias the cylinder stopper 7 of installing at CFG stake top, comes the position that plastic fixer 53 was transferred to the drum through the position of cylinder stopper 7, and the steel reinforcement cage is transferred the position and is injectd, and vibrating device 5 relies on self gravity and steel reinforcement cage self gravity to transfer the steel reinforcement cage, has saved the manual work, improves the degree of automation of this transfer device, accomplishes transferring of steel reinforcement cage. On one hand, the lowering device and the CFG pile driver are combined to work together, tools such as an excavator are replaced by the vibration motor 51, and the reinforcement cage is lowered by means of vibration, so that the construction cost is reduced; on the other hand, this transfer device installation is flat to be saved 4 m's steel reinforcement cage, and transfer time only needs about 3 minutes, very big improvement steel reinforcement cage installation effectiveness.
Example 2, unlike example 1, the cylindrical stopper 7 is removed at the top of the CFG pile. Furthermore, the operation becomes flexible by continuously righting the reinforcement cage which moves downwards through vibration and applying a downward force by an operator; the steel reinforcement cage receives the gravity of vibrating device 5, steel reinforcement cage both and the application of force of operating personnel, and dual effort makes the steel reinforcement cage transfer fast and gets into CFG stake peripherally, accomplishes the construction.
