Detailed implementation mode
[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0026] Embodiment 1
[0027] Please refer to Figures 1 to 8 , a horizontal rotation construction equipment for precast beams, including a support base, support feet, a rotating seat and balls. Four support feet are fixedly connected to the bottom surface of the support base. A rotating seat is arranged in the cylindrical groove opened on the upper surface of the support base. Annularly arranged balls are arranged in the upper raceway opened on the bottom surface of the rotating seat. A lower raceway is opened inside the support base, and the balls are located inside the lower raceway. A clamping groove is opened on the upper surface of the rotating seat, a support assembly is arranged inside the rotating seat, and a rotating assembly is arranged inside the support base.
[0028] The support assembly includes a first support block, a second support block, a U-shaped bracket, a spring, a rotating shaft, a first bending plate, a gear, a second bending plate and a toothed plate. A U-shaped groove is opened inside the rotating seat. The first support block and the second support block are inserted into the U-shaped groove. Both the first support block and the second support block are slidably connected to the rotating seat. A U-shaped bracket is arranged inside the U-shaped groove. A plurality of springs are equidistantly arranged on the bottom surface of the U-shaped bracket. The two ends of the spring are respectively fixedly connected to the rotating seat and the U-shaped bracket. A rotating shaft is arranged inside the U-shaped bracket. A gear is fixedly sleeved on the surface of the rotating shaft. A toothed plate is meshed with the surface of the gear. The toothed plate is attached to the surface of the U-shaped bracket. The toothed plate and the U-shaped bracket are slidably connected. Symmetrically arranged first bending plates and second bending plates are arranged inside the U-shaped groove. Adjacent ends of the first bending plate and the second bending plate are fixedly connected to the rotating shaft.
[0029] Two first bearings are installed inside the U-shaped bracket. Both ends of the rotating shaft are respectively inserted into the two first bearings, and the rotating shaft is rotationally connected to the U-shaped bracket through the first bearings.
[0030] A plurality of equally spaced first triangular blocks are fixedly connected to the bottom surface of the toothed plate. A support plate is arranged below the toothed plate. The support plate is fixedly connected to the rotating seat, and a plurality of equally spaced second triangular blocks are fixedly connected to the upper surface of the support plate.
[0031] A rectangular inner groove is formed inside the U-shaped bracket, and the first triangular block is located inside the rectangular inner groove.
[0032] It should be noted that: the shapes of the first support block and the second support block are the same, and both ends of the first support block and the second support block are in an arc state, ensuring the flexibility of the movement of the first support block and the second support block.
[0033] The working principle of this embodiment: The precast beam is hoisted to the clamping groove formed on the surface of the rotating seat through the hoisting mechanism. During the hoisting process of the precast beam, the upper surface of the precast beam is in a horizontal state. Due to the bottom surface of some special precast beams being inclined, when the precast beam falls into the clamping groove, a part of the bottom surface of the precast beam first fits with the first support block or the second support block. When it first fits with the surface of the first support block, under the action of the gravity of the precast beam, a force is exerted on the first support block, causing the first support block to slide inside the U-shaped groove. The movement of the first support block drives the rotation of the rotating shaft, and then drives the synchronous rotation of the second bending plate. The rotation of the rotating shaft drives the rotation of the gear, and the rotation of the gear drives the movement of the toothed plate meshed with it. During the rotation of the second bending plate, it drives the second support block to move vertically inside the U-shaped groove until the second support block fits with the bottom surface of the precast beam. When both the first support block and the second support block fit with the bottom surface of the precast beam, the precast beam drives the first support block and the second support block to move synchronously during the downward movement. During the movement of the second support block and the first support block, they drive the rotating shaft to move synchronously through the first bending plate and the second bending plate. The movement of the rotating shaft drives the movement of the U-shaped bracket, and the movement of the U-shaped bracket compresses the spring. And during the movement of the U-shaped bracket, it makes the gear and the toothed plate move synchronously. During the movement of the toothed plate, when the surfaces of the first triangular block and the second triangular block fit together, the position of the toothed plate is restricted, thereby avoiding the rotation of the rotating shaft, ensuring that the precast beam will not rotate, and being beneficial to fixing the precast beam in a horizontal state under the action of gravity when the precast beam is horizontally placed inside the rotating seat, solving the problem that the precast beam cannot be kept horizontal during the placement process due to the inclined bottom surface of the precast beam, and improving the applicable range of this swivel construction equipment.
[0034] Embodiment Two
[0035] This embodiment is an improvement made on the basis of Embodiment One. Specifically, please refer toFigures 1 to 8 , the rotating assembly includes a lower coupling shaft, a worm gear, a second bearing, a connecting rod and a worm. A lower coupling shaft is fixedly connected to the bottom surface of the rotating seat. A circular through hole is formed inside the support seat. The lower coupling shaft is located inside the circular through hole. A through groove is formed inside the support seat. The through groove is communicated with the inside of the circular through hole and the cylindrical groove. A worm gear is fixedly sleeved on the surface of the lower coupling shaft. A worm is meshed with the surface of the worm gear. Two second bearings are sleeved on the surface of the worm. The surface of the outer ring of the second bearing is fixedly connected with a connecting rod. The connecting rod is fixedly connected with the support seat. The worm is rotationally connected with the connecting rod through the second bearing.
[0036] A handwheel is installed on the surface of the worm. Both the worm gear and the worm are located inside the through groove.
[0037] The working principle of this embodiment: When it is necessary to rotate the precast beam, rotate the handwheel. The rotation of the handwheel drives the worm to rotate. The rotation of the worm drives the worm gear to rotate. The rotation of the worm gear drives the rotating seat to rotate inside the support seat through the lower coupling shaft. During the rotation of the rotating seat, the resistance during the rotation of the rotating seat can be reduced under the action of the annular array of balls. The rotation of the rotating seat drives the precast beam inside it to rotate synchronously, thereby achieving the effect of driving the precast beam to rotate. And when the worm rotates, under the cooperation of the worm gear and the worm, the position of the rotating seat after rotation can be fixed, which is beneficial to rotating the precast beam when rotating the handwheel. And after the precast beam rotates to an appropriate position, the effect of fixing the position of the rotated precast beam is achieved, improving the use effect of the device.
