Problems solved by technology

[0005] In order to overcome the problem that the hand-held electric heating cone is easy to open the hole on the plastic grid cover plate, the opening is too large due to the shaking of the arm, and the screw is tilted during subsequent installation and use, making it difficult to fasten the screw. Through the opening, the grid cover cannot be fixed, and the inclined opening makes the installed grid cover prone to deflection. The technical problem to be solved by the present invention is to provide an automatic compression grid cover plate, and the grid cover plate opening device with holes in the four corners at the same time

Embodiment 1

[0024] A grid cover opening device, such as Figure 1-5 As shown, it includes a frame 1, a connecting plate 2, a motor base 3, a servo motor 4, a moving mechanism, a hole opening device and a pressing mechanism. On the two supporting feet, which extend to the inside of the frame 1, the motor base 3 is consolidated with the connecting plate 2, the servo motor 4 is installed on the motor base 3, the output shaft of the servo motor 4 faces upward, and the moving mechanism is arranged on the frame 1 and Connected with the servo motor 4, the hole opening device is arranged on the frame 1, the hole opening device is located above the moving mechanism, and the pressing mechanism is arranged on the frame 1 and the moving mechanism.

[0025] When working, put the grid cover plate under the pressing mechanism on the moving mechanism, start the servo motor 4, and the servo motor 4 drives the moving mechanism to move towards the opening device. When the tightened grid cover plate moves to...

Embodiment 2

[0033] On the basis of Embodiment 1, a grid cover opening device also includes a grid box 18, a bent rod seat 19 and a feeding rod 20, the grid box 18 is fixed on the inner wall of the frame 1 ring frame, and Located on the rear side of the pressing mechanism, its bottom is located above the support plate 9 extending out of the baffle plate, the bent bar seat 19 is fixed on the support foot of the frame 1, and one end of the feeding rod 20 is slidably connected to the bent bar seat 19, and the feeding bar 20 It is irregularly curved, and the other end of the feeding rod 20 is bent to one end of the grid box 18 .

[0034] A grid cover plate can be placed in the grid box 18. When a hole needs to be opened, the feeding rod 20 only needs to be pulled forward, and the feeding rod 20 will pull the grid cover plate in the grid box 18 to just below the pressing mechanism. At this time, only need to start the moving mechanism, the grid cover plate can be tightened and sent to the botto...

Embodiment 3

[0038] On the basis of embodiment 2, a kind of grating cover plate opening device also includes push rod 25, swing rod 26, sliding wheel 27, right-angle plate 28, pressure spring 29 and stop bar 30, and push rod 25 rotates Connected to the extension seat of the support frame 11, the push rod 25 has a waist-shaped hole, and one end of the stroke plate 17 is fixed with a stop rod 30, and the push rod 25 is rotated through the waist-shaped hole to connect the stop rod 30, and the swing rod 26 rotates Connected to the right-angle plate 28, the right-angle plate 28 is fixed on the support plate 9, a sliding wheel 27 is installed at the end of the swing rod 26, and the sliding wheel 27 is in contact with the push rod 25, one end of the pressure spring 29 is connected to the right-angle plate 28, and the other end is connected to the swing rod 26.

[0039] When the moving mechanism moved to the left, the swing bar 26 moved to the left, and when the grid cover on the moving mechanism ...

Abstract

The invention relates to the technical field of municipal equipment, in particular to a device for opening holes in a grid cover plate. The technical problem to be solved by the present invention is to provide a grid cover plate opening device that automatically presses the grid cover plate and simultaneously opens holes at four corners. In order to solve the above-mentioned technical problems, the present invention provides such a grid cover opening device, which includes a frame, a connecting plate, a motor base and a servo motor: a moving mechanism, which is arranged on the frame and communicates with the servo Motor connection; hole opening device, set on the frame, for opening holes for the grid cover plate; pressing mechanism, set on the frame and the moving mechanism, used for pressing the grid cover plate . The invention realizes the function of automatically opening holes at the four corners of the grid cover plate, and the electric heating cone can penetrate the grid cover plate to open holes, avoiding the phenomenon of inclination and excessive melting of the opening holes of the grid cover plate, and opening the four corners at the same time , which greatly improves the speed of opening, and the opening is uniform, which is convenient for subsequent installation.

Description

technical field [0001] The invention relates to the technical field of municipal equipment, in particular to a device for opening holes in a grid cover plate. Background technique [0002] The cover plates are mostly used in the sewer and in front of the door of villas. Most of them are grid-type cover plates. During the installation and use of the cover plate, holes need to be opened at the four corners of the cover plate to facilitate the fixing of screws. [0003] There are no openings at the four corners of the newly produced grid cover, and manual drilling is required during installation. Electric drills are generally used for steel cover plates, and electric drills or electric heating iron cones can be used for plastic cover plates. Before manual opening, it is necessary to measure and mark on the grid cover first to prevent the opening position from being wrong. Manual opening needs to open the four corners of the mark in turn, which requires a lot of work. The openi...
