Description

Technical Field

[0001] The utility model relates to a transfer device for steel pipe tiles after rolling during the fabrication of penstocks, and particularly to an automatic turning device for steel pipe tiles. Background Art

[0002] During the fabrication of penstocks, when the tiles formed by rolling steel plates are lifted out of the rolling machine by a lifting device, they are in a horizontal state. After being turned over, they need to be placed on a steel platform for storage and inspection in a "standing" manner, and also for circular assembly on a circular assembly platform in a "standing" manner. The common method for turning over steel pipe tiles is to use 2 lifting devices. Among them, the hook of 1 device is used as the main hook for lifting, and the hook of the other device is used for assistance. Under the unified command of professional lifting personnel, the two lifting devices cooperate with each other to slowly turn over the tiles. This method is labor-consuming, time-consuming, and has certain safety risks, and is not suitable for penstock fabrication projects with a large workload. Therefore, there is an urgent need to develop a set of automatic turning devices for tiles during the fabrication of penstocks, which can achieve smooth turning over of the tiles, and requires convenient construction, safety, and high work efficiency. Summary of the Invention

[0003] The purpose of the utility model is to provide an automatic turning device for penstock fabrication tiles that is simple, lightweight, stable and reliable, easy to transport, disassemble and install.

[0004] The utility model is realized as follows:

[0005] For the automatic turning device for penstock fabrication tiles, the upper ends of two side-by-side vertical main supports are respectively connected to a bracket through a hinge device. One end of the two brackets has a stop block 9, and the other end is connected through a connecting rod 11. There are two counterweight rings 12 on the connecting rod 11, which are connected to both ends of a balancing device through steel wires 3. There is a counterweight block 1 on the balancing device. The steel pipe tile is placed on the two brackets, and one end is connected to the stop block 9.

[0006] The vertical main support is connected to an inclined support rod 2.

[0007] One end of the main beam 5 of the bracket is connected to the end plate of the bracket connecting rod 4. The bottom plates of two vertical supports 7 with a U-shaped cross-section are connected by gusset plates 19 to form a vertical main support. The upper end of the vertical main support is connected to the first connecting plate 8 fixed on the main beam 5 through a hinge device. The hinge shaft 13, nut 14, and backing plate 15 form the hinge device. The lower end of the vertical main support is connected to the main support gusset plate 16. The upper end of the inclined support rod 2 has a second connecting plate 6 connected to the vertical support 7, and the lower end has an inclined support gusset plate 17. The inclined support gusset plate 17 and the main support gusset plate 16 are fixed to the ground concrete foundation through expansion bolts 18.

[0008] The cross-section of the main beam 5 of the bracket is U-shaped, and its open surface is connected to the main beam rib plate 10.

[0009] The bracket is connected to the vertical support through the first connecting plate 8 and the hinge device, enabling the bracket to rotate freely on the main support.

[0010] The balancing device is connected to the bracket. By adding or reducing counterweight blocks on the balancing device, the stable turning of the tile and the automatic reset of the bracket are achieved.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model adopts a set of support structures for the steel pipe tile turning device with stable structure and a set of automatic rotating mechanisms for the steel pipe tiles that can turn relying on the self-weight of the tiles. And by adding or reducing counterweight blocks on the balancing device, the stable turning of tiles with different weights and the automatic reset of the bracket are realized.

[0013] By using this technology, after a coiling machine rolls the tiles, a gantry crane directly hoists the rolled tiles onto the steel pipe tile turning device for turning, and then hoists them to the tile inspection platform for storage and inspection. The entire work process is simple and fast. It not only saves the equipment investment of adding a hoisting device for cooperation in turning, but also does not occupy too much time of the gantry crane, enabling the gantry crane to have sufficient time for hoisting operations of other processes, greatly improving the utilization efficiency of the gantry crane, accelerating the production progress of the penstock, and ensuring construction safety.

One end of each of the two brackets has a stop block 9, and the other ends are connected through a connecting rod 11. There are two counterweight hanging rings 12 on the connecting rod 11, which are connected to both ends of a balancing device through steel wires 3. There is a counterweight block 1 on the balancing device. The steel pipe tile is placed on the two brackets, and one end thereof is connected to the stop block 9.

[0026] (I) Manufacturing of the automatic tilting device for steel pipe tiles in penstock manufacturing. Before installing the automatic tilting device for steel pipe tiles in penstock manufacturing, the manufacturing work of the main components: the bracket and the main support should be completed first. Among them: the bracket is welded by 2 main beams 5 (channel steels), main beam rib plates 10 (steel plates), connecting rods 11 (seamless steel pipes), first connecting plates 8 (steel plates), connecting rod end plates 4 (steel plates), tile stop blocks 9 (steel plates), and counterweight hanging rings 12 (steel bars); both of the 2 vertical supports 7 are composed of two channel steels with their limbs facing away from each other, and are welded through gusset plates 19 (steel plates), and a double plate 16 (steel plate) is welded at the bottom to form the main support.

[0027] (2) Installation of the automatic turning device for the steel penstock segment. First, mark the installation position line of the main support on the ground in advance, then hoist the main support and fix it firmly on the ground by driving expansion bolts. Next, hoist the bracket and assemble it with the main support through the hinge shaft 13 (round steel), nut 14 (standard part), and backing plate 15 (steel plate). Weld the inclined support rod 2 to the second connecting plate 6 to enhance the stability of the support, and weld the backing plate 17 (steel plate) at the bottom of the inclined support. Finally, pass the lifting ring 12 through the steel wire rope 3 and hang the balance device hanging basket and counterweight 1.
