[0005] The current technology has incomplete considerations and has the following disadvantages: there are problems such as low efficiency, uncontrollable quality, low automation level, and no guarantee of worker safety.

[0006] To solve one of the above problems, an automatic stirrup bar arranging device for the top slab of a box girder is urgently needed. Content of the Utility Model

[0007] According to the deficiencies in the above prior art, the technical problem to be solved by the utility model is: how to replace manual labor to complete heavy and repetitive bar arranging work, while optimizing the work process, reducing unnecessary links and steps, thereby improving labor efficiency and work quality. For this purpose, an automatic stirrup bar arranging device for the top slab of a box girder is provided.

[0008] The automatic stirrup bar distributing device for the box girder top plate described in the utility model includes a stirrup bar support frame, and a set of traveling rails are respectively arranged on both sides of the stirrup bar support frame. It is characterized in that: it further includes an active distributing vehicle, which is installed on the traveling rails and can horizontally move along its length direction. The active distributing vehicle includes a carrying vehicle frame located above the stirrup bar support frame and a traveling system installed at the bottom of the carrying vehicle frame. The carrying vehicle frame is equipped with a distributing device and a feeding device for supplying stirrup bars to the distributing device.

[0009] Driven by the traveling system, the carrying vehicle frame can be driven to move along the length direction of the traveling rails. The traveling rails are consistent with the length direction of the stirrup bar support frame, so that the carrying vehicle frame can move from one end to the other end above the stirrup bar support frame.

[0010] During the process of the carrying vehicle frame moving forward, the feeding device can supply materials to the distributing device. The distributing device transfers multiple groups of stirrup bars on the feeding device to the stirrup bar support frame one by one, so that multiple groups of stirrup bars are arranged on the stirrup bar support frame according to the set interval rule to realize the automatic distribution of stirrup bars.

[0011] It can replace manual labor to complete heavy and repetitive stirrup bar distribution work, thus optimizing the work process, reducing unnecessary links and steps; improving labor efficiency and work quality; reducing labor intensity and production costs; improving the working environment of employees and enhancing the comfort and satisfaction of employees' work.

[0012] Preferably, the feeding device includes a tail beam and a pushing cross beam. A plurality of horizontally arranged stirrup bar support rods are connected along the length direction of the tail beam. The plurality of stirrup bar support rods are arranged at intervals and all penetrate the pushing cross beam. Assembly holes matched with the stirrup bar support rods for sliding are opened on the pushing cross beam. The two ends of the pushing cross beam are respectively connected with a left pushing power mechanism and a right pushing power mechanism.

[0013] The loading process is as follows: The setting of the stirrup bar support rods provides effective support for the stirrup bars. Workers place the top plate stirrup bars produced at the bending center adjacent to each other in sequence along the length direction of the stirrup bar support rods. The left pushing power mechanism and the right pushing power mechanism can be used to cooperate with the pushing cross beam to push the stirrup bars on the stirrup bar support rods in the direction close to the distributing device to supply stirrup bars to the distributing device.

[0014] Preferably, the left pushing power mechanism includes a motor mounting base A connected to the pushing cross beam and two sets of slide rails A mounted on the bearing frame. A slider A cooperating with the slide rail A is arranged on the lower surface of the motor mounting base A. A driving motor A is mounted on the upper surface of the motor mounting base A. The power output shaft A of the driving motor A penetrates through the motor mounting base A and extends below the motor mounting base A, and a driving gear A is mounted at the end of the power output shaft A. A rack A meshing with the driving gear A is mounted on the bearing frame.

[0015] In this application, the driving motor A is used as the power. Through the meshing of the gear and the rack, the motor mounting base A is driven to move along the length direction of the slide rail A. Cooperating with the pushing cross beam, the stirrup on the stirrup support rod is pushed towards the direction close to the cloth feeding device to supply the stirrup to the cloth feeding device.

[0016] Preferably, the right pushing power mechanism has the same structure as the left pushing power mechanism. The left pushing power mechanism and the right pushing power mechanism need to move synchronously to control the pushing cross beam to move along the length direction of the stirrup support rod.

The two ends of the movable cloth feeding cross beam are respectively connected with a left cross beam power mechanism and a right cross beam power mechanism. A plurality of groups of electromagnets and a plurality of groups of stirrup descending devices are arranged at intervals on the rear side surface of the movable cloth feeding cross beam.

[0019] The cloth feeding process is as follows: The left cross beam power mechanism and the right cross beam power mechanism can drive the movable cloth feeding cross beam to drive the energized electromagnet close to the stirrup on the stirrup support rod, adsorb the stirrup on the electromagnet, and then control the movable cloth feeding cross beam to move away from the stirrup support rod, so that a group of stirrups on the stirrup support rod can be taken off from the stirrup support rod until it is transferred to the outside of the bearing frame, solving the interference caused by the bearing frame to the downward movement of the stirrup. Finally, the stirrup descending device is used to transfer the stirrup adsorbed on the electromagnet to the stirrup tire rack.

A pneumatic gripper is mounted on the sliding table of the electric slide table module. The pneumatic gripper uses the telescopic cylinder to drive the opening and closing of the gripper body.

[0021] The working process of the stirrup downward shifting device is as follows: After a set of stirrups on the stirrup support rod are removed from the stirrup support rod by using an electromagnet, the lifting mechanism is used to drive the pneumatic gripper to descend. The pneumatic gripper grabs the stirrups adsorbed on the electromagnet, and then the electromagnet is controlled to cut off the power to cancel the adsorption. Then, the lifting mechanism is continuously used to drive the pneumatic gripper to descend. After reaching the lowest position, the opening and closing cylinder of the pneumatic gripper drives the gripper body to release the stirrups. Under the action of gravity, the top plate stirrups fall into the specified positioning slots of the stirrup jig. Finally, the lifting mechanism is continuously used to drive the pneumatic gripper to rise to the highest position. At the same time, the left feeding power mechanism and the right feeding power mechanism can cooperate with the feeding cross beam to push the stirrups on the stirrup support rod to move in the direction close to the cloth feeding device, so as to fill the vacancy of a set of stirrups.

[0022] Then the traveling system drives the carrier frame to move one slot, and then the cloth feeding device can be used for cloth feeding again, and the feeding device can be used for replenishing materials again.

[0023] Preferably, the left power mechanism of the cross beam includes a motor mounting seat B connected to the moving cloth feeding cross beam and two groups of slide rails B installed on the carrier frame. A slider B that cooperates with the slide rail B is arranged on the lower surface of the motor mounting seat B. A driving motor B is installed on the upper surface of the motor mounting seat B.

A rack B that meshes with the driving gear B is installed on the carrier frame.

[0024] In this application, the driving motor B is used as the power. Through the meshing of the gear and the rack, the motor mounting seat B is driven to move along the length direction of the slide rail B, and cooperate with the moving cloth feeding cross beam to drive the electromagnet, the pneumatic gripper and the lifting mechanism to move.

A rack A7.3 meshing and driving with the driving gear A is installed on the loading frame 1.1.

[0046] In this application, with the driving motor A7.4 as the power, through the meshing of the gear and the rack, the motor mounting base A7.1 is driven to move along the length direction of the slide rails A7.2, and in cooperation with the pushing beam 6, the stirrups 17 on the stirrup support rods 5 are pushed in the direction close to the distributing device 9, so as to supply the stirrups 17 to the distributing device 9.

[0047] Furthermore, the right pushing power mechanism 8 has the same structure as the left pushing power mechanism 7. The left pushing power mechanism 7 and the right pushing power mechanism 8 need to move synchronously to control the pushing beam 6 to move along the length direction of the stirrup support rods 5.

[0048] Further, the walking system 1.2 includes a left front wheel, a right front wheel, a left rear wheel, and a right rear wheel that are respectively rotatably installed at the four corners of the load-bearing vehicle frame 1.1.
