[0002] Cement concrete pavement paver is an important equipment used in the construction of cement concrete pavement or airport cement concrete pavement. It has the functions of spreading, vibrating and leveling concrete mixture and is a self-propelled unit.

[0003] The mold of the existing concrete slipform paver is connected to the mold mounting frame by bolts and nuts, which is cumbersome, time-consuming and labor-intensive to operate. A similar quick connection device is currently a quick connection device for replacing accessories on an excavator. When the excavator uses the quick connection device to replace accessories, the fixed claw at one end of the quick connection device is first hung on the accessory, and then the boom is lifted. The accessory is at the front end of the boom and flips down by its own weight to hook the claw at the other end. It is then tightened and locked manually or hydraulically. However, the concrete slipform machine and the mold are limited by their structure and cannot be flipped. Therefore, the conventional quick connection device cannot be used on the concrete slipform machine. Therefore, it is necessary to design a quick connection device for the concrete slipform paver mold to solve the above problems. Utility Model Content

[0006] The driving assembly includes a hydraulic cylinder, a moving block and two connecting parts. A connecting part is installed inside the quick connector housing. One end of the outer rod of the hydraulic cylinder is installed on one side of the connecting part. The moving block is connected to one end of the inner rod of the hydraulic cylinder. The two connecting parts are respectively rotatably connected to the two sides of the moving block, and one side of the connecting part is welded to the outside of the rotating column.

[0007] Preferably, the clamping member is specifically a connecting claw, and the two connecting claws are fixedly mounted on both ends of the rotating column respectively.

[0009] Preferably, two balancing valves are installed in the inner cavity of the quick connector housing, and the two balancing valves are respectively used to maintain the loads of the two hydraulic cylinders.

[0010] Preferably, the extension and retraction of the hydraulic cylinder is controlled by a switch, a solenoid valve and a controller.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The quick connection device of the concrete slipform paver mold is used. When the groove on the mold surface is facing the connecting claw, the mold is moved so that the connecting claw enters the groove. By starting the hydraulic cylinder, the hydraulic cylinder pulls the moving block to move, and the moving block drives the connecting piece to rotate, thereby driving the rotating column to rotate, and the rotating column drives the connecting claw to rotate and evert, thereby completing the connection between the mold and the paver.
