Description

Technical Field

[0002] In the engineering field, the steel bar structure of reinforced concrete structures such as box girders and bridge towers is relatively complex. With the development of industrialized construction, automated production lines are widely used in the flexible processing and forming of various types of steel bar blocks. For prefabricated small box girders, the bottom plate steel bar blocks and the left and right side web steel bar blocks are usually produced separately by mechanization, and then these three blocks need to be assembled into U-shaped steel bar components.

[0003] The current assembly process is mainly carried out in the steel production workshop. Two gantry trucks are used with special hoists to sequentially hoist the bottom plate steel bar blocks and the left / right side web plate steel bar blocks into the U-shaped component frame to complete the assembly. The web plate steel bar blocks are initially in a flat state and require the use of special hoists and turning frames for posture adjustment and turning operations before they can be assembled smoothly. This traditional process has the problems of complicated procedures, long gantry truck occupancy time, and long assembly cycle. At the same time, since the bottom plate and web plate steel bar blocks need to be temporarily stored before assembly, a larger stacking area is required on site, which is not conducive to the efficient use of space resources. In addition, assembly The process still requires the deployment of multiple operators. Although it has been improved compared to the traditional loose-binding steel bar process, it has limited effect in achieving mechanization to replace manual labor and intelligent reduction of manpower. Although the overall assembly has reduced labor intensity and the number of operators to a certain extent, the core goal of the current industrialized construction technology of steel bar components is to further improve product quality, achieve efficiency improvement through reduction in manpower, reduce dependence on the skill level of operators, and improve the mechanization and intelligence level of steel bar skeleton production, so as to ensure the stability and consistency of construction quality.

The U-shaped steel bar block is composed of a bottom plate steel bar block 3 and two web plate steel bar blocks 4. The bottom plate steel bar block 3 and the two web plate steel bar blocks 4 are all produced and formed by mechanized equipment. This is the existing technology in this field, so it will not be described in detail here.

[0019] The automatic assembly device includes a base plate frame 1 and a web plate frame 2, wherein the base plate frame 1 includes a longitudinal slide rail 10 and a longitudinal telescopic cylinder 14 arranged longitudinally. In this embodiment, the number of the longitudinal slide rail 10 and the longitudinal telescopic cylinder 14 are both two, and the longitudinal slide rail 10 is fixed to the ground by anchor bolts. A base plate support frame 11 for placing the base plate steel bar block 3 is slidingly provided on the longitudinal slide rail 10. The base plate support frame 11 slides with the longitudinal slide rail 10 through a first pulley 12 provided at the bottom. The telescopic end of the longitudinal telescopic cylinder 14 is connected to the base plate support frame 11, and one end of the longitudinal telescopic cylinder 14 is hinged to the ground, and the telescopic end is hinged to the base plate support frame 11, so that the longitudinal movement of the base plate support frame 11 can be realized by the extension and contraction of the longitudinal telescopic cylinder 14. A placement positioning component is provided on the top of the base plate support frame 11 for positioning the placement position of the base plate steel bar block 3 to facilitate subsequent assembly.

[0020] There are two web tire frames 2, which are symmetrically arranged on both sides of the bottom plate tire frame 1. The web tire frame 2 includes transverse rails 20 and transverse telescopic cylinders 23 arranged laterally. In this embodiment, there are four transverse rails 20, which are fixed to the ground by anchor bolts. There are three transverse telescopic cylinders 23. A transverse support frame 21 is slidingly arranged on the transverse rail 20. The transverse support frame 21 slides with the transverse rail 20 through a second pulley 22 provided at its bottom. The telescopic end of the transverse telescopic cylinder 23 is connected to the transverse support frame 21. One end of the transverse telescopic cylinder 23 is hinged to the ground, and the telescopic end is hinged to the transverse support frame 21, so that the web tire frame 2 includes a transverse rail 20 and a transverse telescopic cylinder 23. The extension and retraction of the telescopic cylinder 23 can realize the lateral movement of the transverse support frame 21. A flip support frame 24 is hingedly provided on the transverse support frame 21, and the hinge point of the two is located on the side close to the bottom plate tire frame 1. A flip telescopic cylinder 25 is provided in the transverse support frame 21 for controlling the flipping of the flip support frame 24. One end of the flip telescopic cylinder 25 is hingedly provided on the bottom plate of the transverse support frame 21, and the telescopic end is hinged to the bottom of the flip support frame 24, so that the flip support frame 24 can be controlled to flip by the extension and retraction of the flip telescopic cylinder 25. A positioning and locking component is provided on the top of the flip support frame 24 for positioning and fixing the web steel bar block 4 to facilitate subsequent assembly.

[0021] With such a design, the bottom plate steel bar block 3 and the two web plate steel bar blocks 4 can be installed and placed on the bottom plate cradle 1 and the two web plate cradles 2 respectively at the assembly position requirements, and the longitudinal sliding of the bottom plate support frame 11 can avoid the cross stirrups of the bottom plate steel bar block 3 and the web plate steel bar block 4 from interfering with each other during the assembly process, so that the cross stirrups at the connection maintain a certain gap, creating conditions for assembly, and then the web plate steel bar block 4 is flipped to the assembly angle by flipping the flip support frame 24. At this time, the web plate cradle 2 maintains a certain distance from the bottom plate cradle 1, so that The flipping creates the conditions, and after the flipping is completed, the transverse stirrups of the web steel bar block 4 and the bottom plate steel bar block 3 can be interlaced through the push of the transverse telescopic cylinder 23 to achieve a preliminary connection, and then the gap between the transverse stirrups is eliminated through the reverse movement of the bottom plate support frame 11, so that the transverse stirrups of the web steel bar block 4 and the bottom plate steel bar block 3 are tightly attached, creating conditions for connection, thereby realizing automated assembly. This time, the completed bottom plate steel bar block 3 and web plate steel bar block 4 can be directly placed on the bottom plate frame 1 or the web plate frame 2, avoiding the need for additional storage space.

[0022] In the preferred embodiment, the placement and positioning component includes a bottom plate comb groove 13 arranged on the four sides of the top of the bottom plate support frame 11, which is used to clamp the transverse stirrups and longitudinal bars of the bottom plate steel bar block 1, wherein the number of notches on the bottom plate comb groove 13 is adapted to the transverse stirrups and longitudinal bars of the bottom plate steel bar block 1, thereby realizing the transverse and longitudinal positioning of the bottom plate steel bar block 1 during placement and ensuring the accuracy of assembly.

[0023] In the preferred embodiment, the positioning and locking assembly includes web comb grooves 26 arranged on the four sides of the top of the flip support frame 24, which are used to clamp the transverse stirrups and longitudinal bars of the web steel bar block 4, thereby realizing the transverse and longitudinal positioning of the web steel bar block 4 when placed, ensuring the accuracy of assembly. In addition, a baffle 27 is provided on the outer side of the web comb groove 26 close to the bottom plate frame 1. The baffle 27 can support the bottom of the web steel bar block 4 during the flipping process to prevent it from slipping. A locking mechanism 28 is provided on the web comb groove 26 on the other side. The locking mechanism 28 avoids collapse due to the shift of the center of gravity during the flipping process.

A locking hook 281 is rotatably provided on the connecting shaft 280, and an anti-detachment cap is provided at the end of the connecting shaft 280 to prevent the locking hook 281 from detaching. The locking hook 281 can lock the transverse stirrups of the web steel bar block 4 in the notch of the web comb groove 26 by rotation. At the same time, when the locking hook 281 is reversed and opened, it can completely detach from the range of the notch to avoid affecting the normal installation of the web steel bar block 4.

[0033] The Z-axis adjustment mechanism includes a plurality of Z-axis telescopic cylinders 158 arranged on the X-axis moving frame 155. The specific number of the Z-axis telescopic cylinders 158 can be adjusted according to actual needs. The adjustment support platform 159 is arranged on the telescopic end of the Z-axis telescopic cylinder 158, so that the height of the X-axis moving frame 155 can be adjusted by the extension and retraction of the Z-axis telescopic cylinder 158.
