Technical Field

[0001] This application relates to the technical field of slotting equipment for hydropower installation, and particularly to an automatic slotting equipment for hydropower installation. Background Art

[0002] During the construction process of hydropower pipelines, operators often slot on walls and floors. Currently, the construction efficiency of operators manually using slotting machines for slotting is relatively low. In order to improve the slotting efficiency, some operators use automatic slotting equipment for slotting.

[0003] In the related art, a Chinese invention patent with the publication number CN106869458B discloses an automatic slotting equipment for hydropower installation, which includes a base. An installation plate is hinged on the base. A slotting mechanism capable of slotting the ground is provided on the installation plate. A track wheel mechanism is provided on the lower end surface of the base. A track mechanism capable of freely expanding and contracting is provided under the track wheel. A driving mechanism capable of driving the track wheel to move on the track mechanism is provided on the base. A hook wheel mechanism capable of being hooked into the track mechanism to prevent the equipment from detaching from the track mechanism is provided on the base. An adjusting mechanism capable of adjusting and fixing the height of the slotting mechanism is provided on the installation plate.

[0004] In view of the above related art, the operator needs to first install the track mechanism on the ground, and then use the adjusting structure to adjust the height of the slotting mechanism. When the ground is uneven, on the one hand, the track mechanism is not easy to install, and on the other hand, in order to ensure the consistent slotting depth of the slotting mechanism, the operator needs to repeatedly adjust the height of the slotting mechanism, thus easily reducing the slotting efficiency. Summary of the Invention

[0005] In order to improve the applicability and slotting efficiency of the slotting equipment, this application provides an automatic slotting equipment for hydropower installation.

A lifting assembly for adjusting the height of the workbench is provided on the installation plate. A driving assembly for driving the installation plate to move is provided on the installation plate.

[0008] By adopting the above technical solution, the operator first installs the base and the support rod, then starts the cutting mechanism. Next, the operator controls the height of the workbench by using the lifting component. The change in the height of the workbench drives the change in the height of the cutting mechanism, so that the cutting mechanism cuts a groove with a depth consistent with the designed depth. Finally, the operator uses the driving component to move the mounting plate along the length direction of the guide rod, thus realizing automatic grooving. The settings of the base, the support column and the guide rod are beneficial to avoiding the influence of uneven ground on the grooving depth, reducing the number of times the operator adjusts the height of the workbench, and thus improving the adaptability and grooving efficiency of the grooving equipment.

The rotation of the first worm makes the first worm gear rotate. The rotation of the first worm gear makes the lead screw rotate. The rotation of the lead screw makes the moving column move along the length direction of the fixed sleeve.

The fixing component includes a threaded rod that penetrates through the mounting plate and is in threaded cooperation with the mounting plate, a clamping block fixedly connected to one end of the threaded rod, and a knob fixedly connected to the other end of the threaded rod. The clamping block is clamped with the rack.

[0016] By adopting the above technical solution, the operator rotates the knob, which causes the threaded rod to rotate. The rotation of the threaded rod causes the clamping block to move towards the rack. When the clamping block is clamped with the rack, the clamping block and the rack cooperate to fix the position of the mounting plate.

[0017] Preferably, a rotating component for driving the guide rod to rotate is arranged on the support rod. The rotating component includes a positioning rod that penetrates through the support rod, a second worm gear fixedly sleeved on the positioning rod, and a second worm that penetrates through the support rod and meshes with the second worm gear.

[0020] By adopting the above technical solutions, the setting of the auxiliary rod and the roller is beneficial to assist in supporting the mounting plate on the one hand, thereby improving the stability of the movement of the mounting plate. On the other hand, the scale groove on the auxiliary rod facilitates the operator to check the degree of ground unevenness, so as to judge whether the cutting mechanism can cut the designed depth; the setting of the pressing assembly makes the mounting plate detachably connected to the auxiliary rod on the one hand, and makes the roller closely adhere to the ground on the other hand, thereby improving the accuracy of measurement.

[0046] The implementation principle of an automatic grooving device for hydropower installation in an embodiment of this application is as follows: The operator uses the rotating wheel 121 to move the base 1 and the support rod 11 to an appropriate position. Then, the operator rotates the rotating wheel 54. The rotating wheel 54 makes the positioning rod 51 rotate through the cooperation of the second worm gear 52 and the second worm 53, thereby facilitating the operator to control the inclination angle of the guide rod 2. Then, the operator uses the power motor 81 to drive the cutting wheel 82 to rotate. The operator then uses the lifting assembly 4 to control the height of the workbench 35. The change in the height of the workbench 35 drives the change in the height of the cutting mechanism 8, so that the cutting mechanism 8 cuts a groove with a depth consistent with the designed depth. Finally, the operator uses the driving assembly 6 to move the mounting plate 3 along the length direction of the guide rod 2, thereby realizing automatic grooving. The settings of the base 1, the support column, and the guide rod 2 are beneficial to avoiding the influence of uneven ground on the grooving depth, and are beneficial to reducing the number of times the operator adjusts the height of the workbench 35, thereby improving the adaptability and grooving efficiency of the grooving device.
