Among them, the drainage ditch mainly includes a ditch body and a cover plate. The ditch body is a U-shaped structure cast by concrete, and the cover plate of the drainage ditch is made of steel.

[0003] During construction, the drainage ditch earthwork is first excavated, and then the prefabricated concrete ditch body is laid in the drainage ditch earthwork in sequence, and finally the cover plate is laid on the U-shaped ditch body. The above operations are all completed manually, which is time-consuming, labor-intensive, inefficient and costly. Summary of the invention

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A modular splicing construction device for a drainage ditch and a top cover plate, comprising a construction vehicle, a cover plate feeding mechanism, a ditch body conveying mechanism, a ditch body positioning mechanism and a splicing mechanism;

[0007] The construction vehicle comprises a tractor and a carrier vehicle, the carrier vehicle is connected to the tractor through a towing structure, the carrier vehicle comprises a carrier platform, a walking mechanism and a lifting mechanism for adjusting the height of the carrier platform, the carrier platform is provided with a construction limit plate for extending into the drainage ditch earthwork, the construction limit plate extends downward compared to the carrier platform, two construction limit plates are provided and are arranged in parallel, and the extension direction of the construction limit plates is parallel to the side wall of the drainage ditch earthwork;

[0008] The cover plate feeding mechanism is arranged on the bearing platform, and comprises a storage rack for storing the cover plates and a pushing mechanism for pushing out the cover plates in the storage rack; a mounting groove for placing the cover plates is arranged on the top of the groove body; when the groove body is positioned, the cover plate at the bottom of the storage rack is aligned with the mounting groove of the groove body;

[0009] The groove body transport mechanism includes a multi-axis mechanical arm and a clamp for clamping the groove body, and the clamp is arranged at the end of the multi-axis mechanical arm;

[0010] The ditch body positioning mechanism includes a positioning support mechanism and a positioning clamping mechanism. The positioning support mechanism is provided with two groups and is relatively arranged between two construction limit plates. Each group of positioning support mechanisms includes a support plate and a support driving mechanism. The driving direction of the clamping driving mechanism is parallel to the extension direction of the drainage ditch. The positioning clamping mechanism is provided with two groups and is relatively arranged on the bearing platform. Each group of positioning clamping mechanisms includes a clamping plate and a clamping driving mechanism. The driving direction of the clamping driving mechanism is perpendicular to the extension direction of the drainage ditch.

[0011] The splicing mechanism includes a device for splicing the groove body being installed with the installed groove body.

[0012] The working principle of the modular splicing construction device for the drainage ditch and top cover is as follows:

[0013] During work, the ditch body to be installed is first placed on one side of the drainage ditch in sequence along the extension direction of the drainage ditch, and the carrying vehicle is pulled by a tractor to move to the top of the drainage ditch. At this time, two construction limit plates are located above, and the height of the carrying platform is lowered by the lifting mechanism, so that the two construction limit plates enter the drainage ditch soil.

[0014] Preparation for construction begins. The mechanical arm drives the clamp to approach the ditch body on one side of the drainage ditch, and the clamp is used to clamp the ditch body. The mechanical arm drives the clamp to place the ditch body on two pallets located in the two construction limit plates; the two sets of clamping drive mechanisms respectively drive the corresponding clamps to move toward each other, and the ditch body is centered. At this time, the cover plate at the bottom of the storage rack is aligned with the installation groove of the ditch body (the volume and weight of the cover plate are small, which is convenient for unified storage and automatic loading); the pushing mechanism pushes the bottom cover plate toward the ditch body, so that the cover plate enters the installation groove of the ditch body until the cover plate is completely separated from the storage rack; the two sets of supporting drive mechanisms respectively drive the corresponding pallets to move in the opposite direction, and no longer support the ditch body, so that the ditch body and the cover plate fall freely into the drainage ditch soil; finally, the ditch body being installed is pushed toward the installed ditch body by the splicing mechanism, so that the ditch body being installed is joined with the installed ditch body to form a continuous drainage ditch structure.

[0015] In a preferred embodiment of the present invention, the traveling mechanism comprises a traveling wheel and a wheel frame, one end of the wheel frame is directly or indirectly connected to the bearing platform, and the other end of the wheel frame is rotatably connected to the traveling wheel.

Through the above structure, the wheel frame can be driven to swing around the rotation center of one end, thereby realizing the lifting and lowering adjustment of the bearing platform, so as to lower the construction limit plate into the drainage ditch.

[0017] Furthermore, the traveling wheels and wheel frames are each provided with four groups, and along the direction of movement, a synchronization rod is provided between the front and rear wheel frames located on the same side.

[0018] In a preferred embodiment of the present invention, the ejection mechanism comprises a mounting seat and a push plate, an ejection drive motor and an ejection transmission assembly arranged on the mounting seat;

[0019] The mounting seat is located below the material storage rack;

[0020] The push plate is arranged on the mounting seat through a slidable structure;

[0021] The push-out transmission assembly includes a push-out transmission gear and a push-out transmission rack.

The axis of the push-out transmission gear is perpendicular to the extension direction of the drainage ditch. The push-out transmission rack is fixedly arranged on the lower surface of the push plate. In the non-loading state, the push plate is located on the side of the storage rack away from the ditch body positioning mechanism, and the push plate is aligned with the cover plate located at the bottom of the storage rack. Through the above structure, under the drive of the push-out drive motor, the push-out transmission gear and the push-out transmission rack drive the push plate to press against the rear of the cover plate located at the bottom of the storage rack, and then push the cover plate forward so that the cover plate is inserted into the corresponding installation groove of the ditch body to complete the cooperation between the two.

[0022] Furthermore, the push-out transmission assembly also includes a synchronous transmission structure, which includes a synchronous belt and a synchronous wheel. Two synchronous wheels are provided and arranged along the extension direction parallel to the drainage ditch, and the synchronous belt is connected between the two synchronous wheels; two push-out transmission gears are provided and are coaxially connected to the two synchronous wheels respectively, and the spacing between the two push-out transmission gears is less than the length of the push-out transmission rack. Through the above structure, the push plate is driven by the two push-out transmission gears in turn, which can not only push the cover plate to the ditch body in place, but also shorten the length of the push plate as much as possible, which is very clever and practical.

[0023] A preferred embodiment of the present invention is that the multi-axis mechanical arm is arranged on a tractor.

[0024] In a preferred embodiment of the present invention, the clamp comprises two clamping blocks and a bidirectional cylinder, and two telescopic rods of the bidirectional cylinder are respectively connected to the two clamping blocks.

[0025] In a preferred embodiment of the present invention, the supporting drive mechanism comprises a supporting drive cylinder, and a telescopic rod of the supporting drive cylinder is fixedly connected to the supporting plate.

[0026] Furthermore, the support plate is connected to the bearing platform via a first sliding guide structure, the first sliding guide structure comprises a guide frame and a sliding part, the guide frame is provided with a guide hole, the sliding part is fixedly connected to the support plate and fits in the guide hole.

[0027] In a preferred embodiment of the present invention, the clamping drive mechanism comprises a clamping drive cylinder, and a telescopic rod of the clamping drive cylinder is fixedly connected to the clamping plate.

[0028] Furthermore, the clamping plate is connected to the bearing platform via a second sliding guide structure, which includes a guide seat and a guide rod, one end of the guide rod is fixedly connected to the clamping plate, and the other end of the guide rod is slidably connected to the guide seat.
