Description

Technical Field

[0001] This utility model relates to the field of box girder steel reinforcement cage production technology, and in particular to a hydraulic traction feeding device for longitudinal reinforcement bars of a steel reinforcement cage. Background Technology

[0002] Box girders are a common structural form in bridge engineering. During manufacturing, they usually require welding to form a steel reinforcement cage, and then pouring cement into the cage to shape it.

[0003] During the fabrication of the box girder reinforcement cage, the arranged bottom and web stirrups of the box girder need to be welded into a three-in-one stirrup. Web longitudinal bars are welded to the outside of the web stirrups of the three-in-one stirrup, and bottom longitudinal bars are welded to the inside of the bottom stirrups of the three-in-one stirrup, thus forming the box girder reinforcement cage.

[0004] When welding the three-in-one stirrups to the web longitudinal bars and bottom slab longitudinal bars to form a box girder reinforcement cage, the three-in-one stirrups need to be arranged on an installation frame. Then, the web longitudinal bars and bottom slab longitudinal bars are moved and passed through the three-in-one stirrups, and installed close to the three-in-one stirrups to weld them together. However, a single reinforcement cage requires a long length and a large number of longitudinal bars. To ensure that a large number of longitudinal bars can pass through the three-in-one stirrups simultaneously, a hydraulic traction feeding device for the longitudinal bars of the reinforcement cage is needed. Utility Model Content

[0005] In view of the above problems, this utility model provides a hydraulic traction feeding device for longitudinal reinforcement bars of steel cage.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A hydraulic traction feeding device for longitudinal reinforcement bars of a steel cage is provided, including a frame, on which a fixed plate and a feeding plate are spaced apart. Both the fixed plate and the feeding plate have multiple rows of mounting holes for the longitudinal reinforcement bars of the bottom plate and the web plate to pass through. Both the fixed plate and the feeding plate are provided with clamping parts for clamping / releasing the longitudinal reinforcement bars. The feeding plate is horizontally and reciprocally linearly slidable on the frame through a sliding component to move the longitudinal reinforcement bars segment by segment. The frame is provided with a first driving member for driving the feeding plate to move.

[0007] Furthermore, the clamping component includes a fixing strip and multiple clamping blocks disposed on both sides of each row of mounting holes. The multiple clamping blocks are provided with clamping parts corresponding to each mounting hole. The multiple clamping blocks are linearly slidably disposed on the fixing plate / feeding plate to cooperate with the corresponding fixing strip to clamp the longitudinal rib passing through the mounting hole. The fixing plate / feeding plate is provided with multiple second driving components that correspond one-to-one with each clamping block and drive the clamping blocks to move.

[0008] Furthermore, the side of the clamping part that contacts the longitudinal rib is designed as a serrated surface.

[0009] Furthermore, the second driving component is a hydraulic drive cylinder, which includes a second cylinder body and a second piston rod. The second cylinder body is disposed on the fixed plate / feeding plate along the moving direction of the corresponding clamping block, and the second piston rod is connected to the clamping block.

[0010] Furthermore, the first driving component employs multiple electric cylinders, each comprising a first cylinder body and a first piston rod. The first cylinder body is mounted on the frame along the moving direction of the feeding plate, and the first piston rod is connected to the feeding plate.

[0011] Furthermore, the sliding assembly includes multiple sets of matching pulleys and slide bars. Multiple slide bars are respectively arranged on the inner top wall and inner bottom wall of the frame along the moving direction of the feeding plate, and multiple pulleys are arranged on the top and bottom of the feeding plate and roll in contact with the corresponding slide bars.

[0012] The beneficial effects of this utility model are as follows: multiple web longitudinal ribs and bottom longitudinal ribs can pass through the mounting holes on the fixed plate and the feeding plate respectively. The clamping parts on the feeding plate clamp and fix each longitudinal rib. The clamping parts on the fixed plate release each longitudinal rib. Then the feeding plate moves away from the fixed plate, so that the longitudinal rib can be moved a certain distance. Next, the clamping parts on the feeding plate release each longitudinal rib. The clamping parts on the fixed plate clamp and fix each longitudinal rib. The feeding plate can move and move closer to the fixed plate so as to transfer the next section of longitudinal rib. Through this reciprocating movement and segment-by-segment transportation of longitudinal ribs, it can be ensured that multiple longitudinal ribs can move synchronously to pass through the three-in-one stirrup, which has the effect of improving the convenience of longitudinal rib feeding.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] This application discloses a hydraulic traction and feeding device for longitudinal reinforcement bars of a steel cage, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a frame 1, on which fixed plates 2 and feeding plates 3 are spaced apart. Both the fixed plates 2 and feeding plates 3 have multiple rows of mounting holes 4 for the longitudinal ribs of the bottom plate and web plate to pass through. Both the fixed plates 2 and feeding plates 3 are equipped with clamping components 5 for clamping / releasing the longitudinal ribs. The feeding plates 3 are horizontally and reciprocally slidably mounted on the frame 1 via sliding components 6 to move the longitudinal ribs segment by segment. The frame 1 is equipped with a first driving component 7 for moving the feeding plates 3.

[0021] In this embodiment, multiple web longitudinal bars and bottom longitudinal bars can pass through mounting holes 4 on the fixing plate 2 and the feeding plate 3, respectively. Clamping members 5 on the feeding plate 3 clamp and fix each longitudinal bar. The clamping members 5 on the fixing plate 2 release each longitudinal bar, and then the feeding plate 3 moves away from the fixing plate 2, thus moving the longitudinal bar a certain distance. Next, the clamping members 5 on the feeding plate 3 release each longitudinal bar, and the clamping members 5 on the fixing plate 2 clamp and fix each longitudinal bar. The feeding plate 3 can then move closer to the fixing plate 2 to facilitate the transfer of the next section of longitudinal bar. By reciprocating linearly with the feeding plate 3 and the clamping members 5 on the fixing plate 2 and the feeding plate 3 alternately clamping the longitudinal bars, it can be ensured that multiple longitudinal bars can move synchronously to pass through the three-in-one stirrup. This improves the convenience of feeding longitudinal bars.

[0022] Reference Figure 4 and Figure 5 The clamping component 5 includes a fixing strip 51 and a plurality of clamping blocks 52 disposed on both sides of each row of mounting holes 4. Each clamping block 52 is provided with a clamping part 521 corresponding to each mounting hole 4. The plurality of clamping blocks 52 are linearly slidably disposed on the fixing plate 2 / feeding plate 3 to cooperate with the corresponding fixing strip 51 to clamp the longitudinal rib passing through the mounting hole 4. The fixing plate 2 / feeding plate 3 is provided with a plurality of second driving components 8 that correspond one-to-one with each clamping block 52 and drive the clamping blocks 52 to move.

[0023] In this embodiment, multiple second driving members 8 can drive each clamping block 52 to move, and each clamping part 521 can cooperate with the corresponding fixing strip 51 to clamp / release the longitudinal rib.

[0024] To improve the fixing effect on the longitudinal reinforcement, the side of the clamping part 521 that contacts the longitudinal reinforcement is made into a serrated surface.

[0025] Specifically, the second driving component 8 is a hydraulic driving cylinder, which includes a second cylinder body and a second piston rod. The second cylinder body is set on the fixed plate 2 / feeding plate 3 along the moving direction of the corresponding clamping block 52, and the second piston rod is bolted to the clamping block 52.

[0026] Specifically, the first driving component 7 uses multiple electric cylinders. Each electric cylinder includes a first cylinder body and a first piston rod. The first cylinder body is mounted on the frame 1 along the moving direction of the feeding plate 3, and the first piston rod is bolted to the feeding plate 3.

[0027] Specifically, the sliding assembly 6 includes multiple sets of matching pulleys 61 and slide rods 62. Multiple slide rods 62 are respectively arranged on the inner top wall and inner bottom wall of the frame 1 along the moving direction of the feeding plate 3. Multiple pulleys 61 are arranged on the top and bottom of the feeding plate 3 and roll in contact with the corresponding slide rods 62.

[0028] In this embodiment, the resistance experienced by the feed plate 3 during movement can be reduced by the rolling contact between the pulley 61 and the slide bar 62.

[0029] The implementation principle of the hydraulic traction feeding device for longitudinal reinforcement bars in this embodiment is as follows: multiple web longitudinal reinforcement bars and bottom longitudinal reinforcement bars can pass through the mounting holes 4 on the fixed plate 2 and the feeding plate 3 respectively. The clamping parts 5 on the feeding plate 3 clamp and fix each longitudinal reinforcement bar. The clamping parts 5 on the fixed plate 2 release each longitudinal reinforcement bar, and then the feeding plate 3 moves away from the fixed plate 2, thus moving the longitudinal reinforcement bar a certain distance. Next, the clamping parts 5 on the feeding plate 3 release each longitudinal reinforcement bar, and the clamping parts 5 on the fixed plate 2 clamp and fix each longitudinal reinforcement bar. The feeding plate 3 can move closer to the fixed plate 2 to facilitate the transfer of the next section of longitudinal reinforcement bar. By reciprocating linearly moving the feeding plate 3 and having the clamping parts 5 on the fixed plate 2 and the feeding plate 3 alternately clamp the longitudinal reinforcement bars, it can be ensured that multiple longitudinal reinforcement bars can move synchronously to pass through the three-in-one stirrups. This has the effect of improving the convenience of longitudinal reinforcement bar feeding.
