[0002] During the production process of sleepers, it is necessary to first install a steel bar framework in a sleeper mold. The steel bar framework includes a truss and stirrups hoisted under the truss by hooks. The traditional installation process is to manually place the stirrups and the truss into the mold respectively, and then connect the stirrups and the truss through hooks. Manual installation is time-consuming and laborious, with low efficiency and low mechanization level. Summary of the Invention

[0003] The purpose of the present invention is to provide an automatic assembly system for the steel bar framework of double-block sleepers.

[0004] To achieve the above purpose, the technical solution of the present invention is: a steel bar framework assembly system for double-block sleepers, including a stirrup conveying device for conveying stirrups, and a truss conveying device for conveying trusses.

[0005] Further, the stirrup conveying device is a roller conveyor line, and the lower part of the hook hooks the stirrup through the roller gap. This facilitates the quick connection between the stirrup and the hook, thereby improving the assembly efficiency.

[0006] Further, the truss conveying device includes a bracket, on which there are two horizontally parallel installation crossbeams. Between the installation crossbeams, there is a transport vehicle for loading trusses, and on the installation crossbeams, there is also a driving mechanism for driving the transport vehicle to translate;

[0007] The transport vehicle includes two horizontally parallel end beams, between which there are connected several bottom beams. On the upper end surface of the bottom beams, there is a lower support plate, and on the lower support plate, there is a lower concave opening.

While the lower steel bars of the truss are embedded in the lower concave opening, the outer upper steel bars of the truss are embedded in the upper concave opening, realizing the loading of the truss; when the transport vehicle loads the truss, the truss is limited through the upper concave opening and the lower concave opening, making the two trusses relatively fixed, facilitating the hanging of the stirrups, and moreover, the transport vehicle ensures the vertical freedom degree of the truss, and the assembled steel bar framework can be directly lifted out by a lifting device;

[0008] The driving mechanism comprises a transmission belt running around the supporting crossbeam, a traveling vehicle is arranged on the transmission belt, and the transport vehicle is hoisted on the traveling vehicle.

When the travel vehicle is traveling, the connecting vertical plate drives the transport vehicle to move horizontally to realize the transportation of the truss. When the travel vehicle moves with the transmission belt, the vehicle body supports the transmission belt to prevent the transmission belt from sagging, thereby ensuring the transportation stability.

[0010] Furthermore, the hook conveying device comprises a conveying chain, on which a plurality of clamps for clamping the hooks are arranged evenly along the conveying direction of the conveying chain.

[0011] Furthermore, the clamp includes a mounting plate arranged on the conveying chain, the mounting plate is fixedly connected to the conveying chain, a longitudinally parallel first positioning plate and a second positioning plate are arranged on the upper surface of the mounting plate, a mutually parallel first rotating shaft and a second rotating shaft are connected between the first positioning plate and the second positioning plate, a first clamping plate is mounted on the first rotating shaft, and a second clamping plate is arranged on the second rotating shaft, the first clamping plate and the second clamping plate are closed under the action of a torque spring to clamp the lower part of the hook to achieve the clamping of the hook. The clamp adopts an elastic opening and closing design, and the hook can enter and exit the clamp by lifting and lowering, so as to quickly realize the loading and taking of the hook.

[0012] Furthermore, the hook installation device includes a robot arm, a rotating arm is provided at the end of the robot arm, at least one pneumatic clamp is installed on the rotating arm, and a clamp block is installed on the clamp of the pneumatic clamp. The clamp block closes with the clamp under the drive of the pneumatic clamp to achieve the grabbing of the hook.

[0013] Furthermore, the rotating arm is provided with two pneumatic clamps, which are respectively arranged at both ends of the rotating arm, and the installation distance of the pneumatic clamps is equal to the conveying spacing of the hook conveying device and the installation interval of the hook on the truss. The hook installation device can complete the grasping and hanging of the two hooks at the same time. When the two hook installation devices are operated synchronously, the stirrups can be hung to ensure the assembly efficiency of the steel skeleton.

[0014] The beneficial effects of the present invention are as follows: the structural design of the present invention is reasonable and reliable, and can realize the automated assembly of the sleeper steel reinforcement skeleton. Moreover, the assembled steel reinforcement skeleton can be output and put into the mold with the cooperation of the lifting equipment. Compared with the traditional manual assembly method, it can greatly improve the assembly efficiency, reduce the production cost, and is conducive to improving the production benefits.
