[0020] Specifically, please refer to Figures 1 to 4 , Figure 1 This is the overall cross-sectional structural schematic diagram of the bevel grinding device applied to the stainless steel lined storage tank cover provided by the embodiment of the present application, Figure 2 For Figure 1 The enlarged view at A; the cross-sectional structural schematic diagram of the swing arm provided by the embodiment of the present application, Figure 3 For Figure 1 The enlarged view at B, Figure 3A schematic diagram of the top plan view of the structure at the base provided in the embodiment of the present application. The groove grinding device 100 applied to the stainless steel lined storage tank cover comprises a base 110 at the bottom and a mounting platform 120 at the top of the base 110. The base 110 and the mounting platform 120 in the embodiment of the present application are both used to mount and install other components. To ensure the stability of each component during use, the base 110 and the mounting platform 120 need to be fixed, wherein the base 110 can be fixed to the ground by setting anchor bolts, and the mounting platform 120 can be fixed to the ground or to the top of the base 110 by a strut. A tray component 140 is rotatably disposed in the middle of the base 110. The tray component 140 can be connected to the middle of the base 110 through a rotating joint so that the tray component 140 can rotate along its central axis under the action of external force. During use, the cover needs to be placed at the top center of the tray component 140. Since the bottom end of the cover is usually arc-shaped, the bottom shape of the tray component 140 can be set according to the specific shape of the cover to facilitate the fit between the tray component 140 and the cover. Semicircular ring hoops 130 are respectively disposed on both sides of the tray component 140. When the two semicircular ring hoops 130 are close to each other, they are annular as a whole and are hooped on the outside of the cover. The semicircular ring-shaped hoop 130 is slidably arranged on the top of the base 110, and the side of the semicircular ring-shaped hoop 130 facing away from the tray part 140 is connected to the first telescopic part 150. After the first telescopic part 150 is extended, the two semicircular ring-shaped hoop members 130 will be close to each other, and vice versa, the two semicircular ring-shaped hoop members 130 will be away from each other. When the two semicircular ring-shaped hoop members 130 are away from each other, it is convenient to put the cover into the tray part 140. A horizontal through hole 131 is provided at the semicircular ring hoop 130, and a friction drum 132 is rotatably provided in the horizontal through hole 131. The friction drum 132 is coaxially connected with a driving motor 133. When the two semicircular ring hoop members 130 are close to each other, the friction drum 132 will abut against the outer wall of the cover. After starting the driving motor 133, the friction drum 132 relies on the friction force to drive the cover as a whole, the tray component 140 and the extrusion disk 162 to rotate slowly along the central axis, thereby facilitating the subsequent angle grinding device 171 and the cleaning device 172 to perform fixed-point operations. The bottom of the mounting platform 120 is located directly above the tray component 140 and is provided with a second telescopic component 160. The bottom of the second telescopic component 160 is connected to a compression plate 162 via a rotating joint 161. When the second telescopic component 160 is extended, the rotating joint 161 will abut against the inner bottom side of the cover, thereby ensuring the stability of the cover during rotation. Naturally, the bottom curvature of the compression plate 162 should be compatible with the curvature of the inner bottom surface of the cover.On both sides of the second telescopic member 160, third telescopic members 170 are respectively arranged. A angle grinding device 171 and a cleaning device 172 are respectively connected to the two third telescopic members 170. The positions of the angle grinding device 171 and the cleaning device 172 are fixed. When the cover rotates, the top edge thereof will pass through the angle grinding device 171 and the cleaning device 172. At this time, the angle grinding device 171 cuts a bevel at the end of the cover in the form of chips, and the cleaning device 172 is used to wipe off impurities and debris adhered to the end of the cover.

[0021] In the embodiment of the present application, the specific working process is as follows. First, the cover is placed on the top of the tray member 140. Subsequently, the first telescopic member 150 extends and drives the two semi-circular hoop members 130 to approach each other. At this time, the friction rotating cylinder 132 will abut against the outer side wall of the cover. After the second telescopic member 160 presses down, the pressing disk 162 will slide along the inner wall of the cover and abut against the inner bottom wall of the cover. Since the arcs of both the pressing disk 162 and the tray member 140 match the arc of the cover, under the combined action of the friction rotating cylinder 132 and the pressing disk 162, the cover can be pushed to a preset position, that is, the cover, and the central axes of the pressing disk 162 and the tray member 140 are coaxial, so as to ensure the accuracy of the positions during the subsequent cleaning processes of the angle grinding device 171 and the cleaning device 172. Subsequently, the driving motor 133 drives the friction rotating cylinder 132 to rotate. The friction rotating cylinder 132 slowly drives the entire cover, as well as the tray member 140 and the pressing disk 162, to slowly rotate along the central axis through friction. At this time, the third telescopic member 170 descends, so as to use the angle grinding device 171 and the cleaning device 172 to complete the chip removal and grinding of the bevel of the cover.

[0022] As can be seen from the above, in the embodiment of the present application, through the above settings, the operator only needs to place the cover at the tray member 140 and take out the cover device after the equipment finishes processing. There is no safety hazard during the working process of the operator, and it is not necessary for the operator to hold the angle grinder 171b manually for a long time to perform grinding, thereby effectively reducing the labor cost and the labor intensity of the operator.

[0023] In some embodiments, the angle grinding device 171 includes a connecting member fixed to the bottom of the third telescopic member 170. One end of the bottom of the connecting member is vertically provided with an extension plate 171a, and the other side of the bottom of the connecting member is angularly connected with an angle grinder 171b. In the embodiment of the present application, when the third telescopic member 170 descends, the extension plate 171a will slide down along the outer side wall of the cover. At the same time, the angle grinder 171b will complete the chip removal of the end of the cover during the slow descent along with the third telescopic member 170. It should be noted that since the chip removal angles of the bevels are different, the angle between the angle grinder 171b and the connecting member here can be set according to the designed angle of the bevel of the cover.

[0024] In some embodiments, the cleaning device 172 includes two clamping plates 172a hinged to the bottom of the third telescopic member 170. The two clamping plates 172a are integrally in the shape of tweezers. A tension spring 172b is commonly connected to the opposite sides of the two clamping plates 172a. Friction materials 172c are respectively fixed to one ends of the bottoms of the two clamping plates 172a. In the embodiments of the present application, the friction materials 172c can be steel wool, sandpaper, etc. Through the above arrangement, during the falling process of the third telescopic member 170, the two clamping plates 172a will clamp on the side wall of the top port of the cover. As the third telescopic member 170 continues to fall, the two clamping plates 172a will open and stretch the tension spring 172b. Under the action of the tension spring 172b, the two clamping plates 172a always generate an inward prestress so as to ensure that the friction materials 172c are closely attached to the outside of the cover to achieve the cleaning of impurities.

[0025] In some embodiments, one end of the first telescopic member 150 close to the semi-circular hoop 130 is connected to the semi-circular hoop 130 through an elastic pressing member 151. In the embodiments of the present application, through the above arrangement, when the first telescopic member 150 extends to a preset position, the elastic pressing member 151 can be squeezed through the elastic pressing member 151, so that the semi-circular hoop 130 and the friction rotating cylinder 132 are closely attached to the outer side wall of the cover and have sufficient friction to drive the cover to rotate.

[0026] In some embodiments, a chute 111 is provided on the base 110, and a slide rail matching the chute 111 is provided at the bottom of the semi-circular hoop 130. In the embodiments of the present application, by providing the chute 111 and the slide rail, the semi-circular hoop 130 can stably slide on the base 110.

[0027] In some embodiments, there are two friction rotating cylinders 132 and two drive motors 133, which are symmetrically arranged on the two semi-circular hoops 130. In the embodiments of the present application, by providing two symmetric friction rotating cylinders 132, the acting force of the friction rotating cylinders 132 on the cover is uniform, ensuring the stability during use.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be covered within the scope of the claims and the description of the present application.
