Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 11A hollow drum flattening device for stainless steel manhole cover production includes a bottom plate 10, an L-shaped support plate 2, a pressing plate 3, a support seat 4 and a plurality of first driving devices 5, wherein the support plate 2 and the support seat 4 are both arranged on the bottom plate 10, and the first driving device 5 is arranged on the support plate 2 for driving the pressing plate 3 to move up and down, and further includes:

[0032] A conveying device 6, used for conveying the manhole cover;

[0033] A detection device, used for detecting the manhole cover transported by the transport device 6;

[0034] The receiving device includes two L-shaped receiving plates 7, a weight-increasing block 8, an L-shaped limiting plate 9, a pull rope 11, and four telescopic rods 12, one end of the telescopic rod 12 is connected to the receiving plate 7, and the other end is rotatably connected to the bottom plate 10, the limiting plate 9 is arranged on the telescopic rod 12, the weight-increasing block 8 is arranged on the receiving plate 7, and the pull rope 11 connects the receiving plate 7 and the pressing plate 3;

[0035] A shielding device, used to shield one end of the receiving plate 7 when in operation;

[0036] A pressure sensor 13, arranged on the shielding device;

[0037] The time relay and controller, the conveying device 6, the detection device, the shielding device, the pressure sensor 13 and the time relay are all electrically connected to the controller. In the present invention, the stainless steel manhole cover is placed upside down on the conveying device 6, and the manhole cover is conveyed forward by the conveying device 6. The detection device detects the moving stainless steel manhole cover. When no hollow drum is detected on the manhole cover, the conveying device 6 conveys the manhole cover to the two receiving plates 7. The original position of the receiving plates 7 is inclined, and the manhole cover slides directly from the receiving plates 7. When a hollow drum is detected on the manhole cover, the detection device sends a signal to the controller, and the controller controls the shielding device to work to shield one end of the receiving plate 7. After the conveying device 6 conveys the manhole cover to the two receiving plates 7, the manhole cover slides and abuts against the pressure sensor 13. The pressure sensor 13 is subjected to the force and sends a signal to the controller. The controller controls the time relay and several first drive devices 5 to work, and controls the conveying device 6 to stop working. Several first drive devices 5 drive the pressure plate 3 to move downward, and the pull rope 11 also moves downward. Due to the weight block 8 After the extension rod 12 is returned to its original position, the extension rod 12 is pulled counterclockwise by the extension plate 7, and the flattened manhole cover slides out from the extension plate 7. Specifically, no reinforcing steel bars are installed in the manhole cover. After the manhole cover is flattened, the steel bars are installed so that they can fit better with the inside of the manhole cover; the conveying device 6 is an existing belt conveyor; and the first driving device 5 is a cylinder.

[0038] As a preferred embodiment of the present invention, it may also have the following additional technical features:

Specifically, the bottom of the outer tube 121 is provided with rotating parts on both sides, and the rotating parts are rotatably connected to the two side walls of the U-shaped seat 101, so that the telescopic rod 12 can rotate relative to the bottom plate 10.

[0040] In this embodiment, at least two L-shaped push rods 102 are provided on the bottom plate 10; the telescopic rod 12 includes an outer tube 121 and a T-shaped rod 122, one end of the T-shaped rod 122 can slide in the outer tube 121, one end of the T-shaped rod 122 is connected to the receiving plate 7, one end of the outer tube 121 is rotatably connected to the bottom plate 10, and an inclined groove 1221 is provided on the T-shaped rod 122. In the original position, the top of the L-shaped push rod 102 abuts against the top wall of the groove 1221. When the pressing plate 3 moves downward, the receiving plate 7 is still inclined, and the T-shaped rod 122 is abutted by the L-shaped push rod 102 and cannot move downward. At this time, the weight-increasing block 8 The bottom of the outer tube 121 rotates on the bottom plate 10 until the limit plate 9 abuts against the bottom plate 10. At this time, the receiving plate 7 is in a horizontal state and the L-shaped top rod 102 is out of the slot 1221. The T-shaped rod 122 moves downward under the action of gravity until the manhole cover cooperates with the support seat 4. When the manhole cover is flattened, due to the action of the weight block 8, the receiving plate 7 moves vertically upward under the action of the pull rope 11. When one end of the T-shaped rod 122 cannot move in the outer tube 121, the top end of the receiving plate 7 is acted on by the pull rope 11 to exert force on the telescopic rod 12 to rotate counterclockwise on the bottom plate 10 and return to its original position. The baffle 19 does not block one end of the receiving plate 7, and the manhole cover slides out from the baffle 19. Specifically, the number of L-shaped top rods 102 can be four, and each T-shaped rod 122 is provided with a slot 1221.

The detection plate 14 is thrusted to move to the left, and the swing rod 17 rotates counterclockwise under the force. When the sensor 15 senses the swing rod 17, it sends a signal to the controller, controls the shielding device to work to shield one end of the receiving plate 7, and controls the second drive device 162 to work to drive the abutment plate 18 to rotate so that it does not contact the top of the detection plate 14. The end of the detection plate 14 that is not provided with the slide groove 171 is provided with a weight-increasing member. The swing rod 17 rotates clockwise in the placement groove 161 to drive the detection plate 14 to rotate so that the bottom of the detection plate 14 is separated from the upper end surface of the manhole cover. The manhole cover is not blocked by the bottom of the detection plate 14 and moves to the receiving plate 7. At the same time, the detection plate 14 rotates and slides in the slide groove 171 through the round rod 141 under the action of its own gravity and returns to the original position. When the pressure sensor 13 is subjected to the force, it sends a signal to the controller, and the controller controls the second drive device 162 to work to drive the abutment plate 18 to rotate in the opposite direction and return to the original position to contact the top of the detection plate 14. Specifically, the second drive device 162 is a servo motor.

After the sensor 15 senses the swing rod 17, it sends a signal to the controller to control the third driving device 21 to drive the baffle 19 to rotate to shield one end of the receiving plate 7. When the time relay reaches the preset value, it sends a signal to the controller, and the controller controls the third driving device 21 to drive the baffle 19 to rotate in the opposite direction, and the baffle 19 returns to its original position, and the manhole cover slides out from the baffle 19. Specifically, the third driving device 21 is a servo motor; a belt conveyor can be arranged on one side of the baffle 19, and the manhole cover falls on the belt conveyor to avoid the manhole cover from being damaged and can be transported out.
