Description

Technical Field

[0001] The present invention relates to the technical field of pipe pile processing, and particularly to an automatic loading device for pipe pile end plates. Background Art

[0002] Prestressed concrete precast piles (pipe piles), as a kind of concrete products, are widely used in industrial and civil buildings, highways, railways, water conservancy, port terminals and other fields. To facilitate the connection of prestressed concrete precast piles, end plates need to be installed at both ends of the concrete precast piles. Before manufacturing prestressed concrete precast piles, the end plates need to be riveted or welded to the strip steel (hoop skin). Whether it is automatic riveting or automatic welding, the end plates need to be transported to the riveting station or welding station one by one. At present, the loading of end plates still requires manual handling one by one, which has extremely high labor intensity and great potential safety hazards.

[0003] To solve the above technical problems, a Chinese utility model patent with the application number CN201820823742.8 (the authorized announcement number is CN208593742U) discloses an "Automatic Loading Device for End Plates and End Plate Loading Pipeline". Among them, the automatic loading device for end plates includes a chassis. The front part of the upper surface of the chassis is provided with an end plate transmission rack that slopes backward and upward. The rear part of the chassis is provided with an end plate chute rack whose upper surface slopes backward and downward. A lifting mechanism is installed on the chassis and the end plate transmission rack. The end plate is lifted by the lifting mechanism to the upper end of the end plate chute rack and then slides down from the end plate chute rack; the end plate loading pipeline includes at least one of the above-mentioned end plate loading devices and a conveyor. The end plate chute rack of the end plate loading device faces the upper surface of the conveyor, and the conveyor is a roller line or a belt conveyor.

[0004] However, there are still certain deficiencies in the above-mentioned automatic loading device for end plates. The end plate transmission rack for placing end plates slopes backward and upward by a corresponding angle to realize the sliding of the end plate under its own gravity onto the end plate chute rack and the action of sliding down from the end plate chute rack to the conveyor. However, since the downward sliding process of the end plate is affected by multiple factors such as the inclination angle of the end plate transmission rack and the specification size of the end plate (different end face areas), it cannot be ensured that the end plate can effectively slide from the end plate transmission rack to the end plate chute rack, and its transfer action reliability is not high, and there are problems that individual end plates are difficult to effectively fall or the sliding is not in place.

[0005] Therefore, the existing automatic loading device for pipe pile end plates still needs to be further improved. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an automatic loading device for pipe pile end plates with reasonable structural design, stable loading action process and high reliability in view of the current situation of the prior art.

[0007] The technical solution adopted by the present invention to solve the above technical problems is as follows: An automatic feeding device for pipe pile end plates, comprising:

[0008] A storage rack, including a strip-shaped slideway with a discharge port, for the end plates to be vertically placed in sequence along the length direction of the strip-shaped slideway;

[0009] An end plate conveying mechanism, arranged on the storage rack, capable of acting on the end plates placed in the strip-shaped slideway of the storage rack, so as to push the end plates to the discharge port position of the strip-shaped slideway in sequence according to the placement order;

[0010] An end plate transfer mechanism, including a first driving device and a pushing frame. The pushing frame is correspondingly arranged at the discharge port position of the strip-shaped slideway, for receiving the end plates coming out of the discharge port of the strip-shaped slideway. The power output end of the first driving device is connected to the pushing frame, so as to drive the end plates shifted onto the pushing frame away from the discharge port of the strip-shaped slideway.

[0011] The pushing action of the push plate of the end plate transfer mechanism can have various forms. For example, the pushing frame can push the end plate in a linear movement mode, or can also push the end plate in a deflecting swing mode; in order to better utilize the circular outer peripheral structure characteristics of the end plate and simplify the structure of the end plate transfer mechanism, the pushing frame is a strip-shaped frame, which is arranged along the width direction of the strip-shaped slideway. The first end of the strip-shaped frame is hinged on one side of the discharge port of the strip-shaped slideway, and the power output end of the first driving device is connected to the second end of the strip-shaped frame, so as to drive the strip-shaped frame to swing up and down. During the process of the second end of the strip-shaped frame swinging upward, it is in an inclined state, and the end plates shifted onto the strip-shaped frame can roll to one side under the action of their own gravity and away from the discharge port of the strip-shaped slideway.

[0012] In order to enable the end plates to smoothly slide onto the pushing frame and prevent the end plates from detaching from the discharge port of the strip-shaped slideway during the conveying process, the pushing frame includes a baffle plate vertically extending corresponding to the discharge port of the strip-shaped slideway and a horizontal supporting plate bent from the lower edge of the baffle plate towards the discharge port. When the strip-shaped frame moves down to the low position, the horizontal supporting plate is flush with or lower than the edge of the discharge port of the strip-shaped slideway.

[0013] In order to enable the end plates stacked on the pushing frame to be transferred one by one in sequence to complete the feeding, the pushing frame further includes a limiting plate vertically arranged and connected to the horizontal supporting plate. The limiting plate is located at the side of the discharge port and is relatively spaced from the baffle plate. The width of the horizontal supporting plate is adapted to the thickness of the end plate. The limiting plate, the horizontal supporting plate and the baffle plate together enclose a rolling groove for only one end plate to be vertically accommodated therein. When the pushing frame moves up, the end plates can roll along the length direction of the rolling groove and away from the discharge port of the strip-shaped slideway.

[0014] In order to enable the end plate to smoothly enter the material rolling groove, the side edge of the limiting plate close to the discharge port bends and extends towards the side away from the material baffle to form a bent portion, and a guiding port for guiding the end plate into the material rolling groove is formed between the bent portion and the material baffle.

[0015] The first driving device can be selected as a first motor or a cylinder. For the flexibility of the end plate transfer operation process and cost consideration, the first driving device is preferably a cylinder.

[0016] As an improvement, the strip-shaped slideway of the storage rack is inclined upward from back to front, and the included angle between the strip-shaped slideway and the horizontal plane is α, where 5° < α < 45°. Preferably, α is 15°. This structural setting can make the end plates in the strip-shaped slideway tilt slightly backward, so as to avoid the end plates falling forward after being transferred to the designated position and causing material blocking problems at the discharge port.

[0017] In order to simplify the structure of the storage rack, the storage rack includes a rectangular frame, which has limiting rods longitudinally extending to limit the left and right sides of the end plate, and support rods longitudinally arranged to support the bottom of the end plate. The two limiting rods and the support rods jointly define the strip-shaped slideway.

[0018] In order to realize the stable forward transfer of the end plates in the strip-shaped slideway, the end plate transfer mechanism includes:

[0019] A pushing plate, which is slidably arranged in the strip-shaped slideway and can abut against the end plate placed at the rearmost position in the strip-shaped slideway;

[0020] A transmission mechanism, including a first transmission unit located below and a second transmission unit located above. The first transmission unit corresponds to the two limiting rods and is connected to the upper side of the pushing plate. The second transmission unit corresponds to the support rod and is connected to the lower side of the pushing plate;

[0021] A second motor, which is drivingly connected to the transmission mechanism and can drive the first transmission unit and the second transmission unit to act synchronously, so as to push the end plates placed in the strip-shaped slideway forward.

[0022] To achieve a firm and stable cooperation between the second motor and the first and second transmission units of the transmission mechanism, the first transmission unit includes a first transmission rod and a first transmission chain. The first transmission rod is arranged along the width direction of the strip-shaped slideway and is rotatably connected to the rectangular frame. The first transmission rod is coaxially provided with a first sprocket, a second sprocket, and a third sprocket. The power output shaft of the second motor is drivingly connected to the first sprocket. The first transmission chain is arranged along the length direction of the strip-shaped slideway and is drivingly connected to the second sprocket. The first transmission chain is also connected to the push plate through a first connecting plate;

[0023] The second transmission unit includes a second transmission rod and a second transmission chain. The second transmission rod is arranged along the width direction of the strip-shaped slideway and is rotatably connected to the rectangular frame. The second transmission rod is coaxially provided with a fourth sprocket and two fifth sprockets. The fourth sprocket is drivingly connected to the third sprocket through a chain. There are two second transmission chains, which extend along the length direction of the strip-shaped slideway and correspond to the two limiting rods one by one. The two second transmission chains are respectively drivingly connected to the two fifth sprockets on the second transmission rod. Both of the two second transmission chains are connected to the push plate through a second connecting plate.

[0024] To facilitate the placement of the first transmission chain and the second transmission chain and improve the stability of the above two chain transmissions, both the limiting rod and the support rod are channel steels. The first transmission chain and the two second transmission chains are all roller chains. The first transmission chain is housed in the channel steel structure of the support rod, and the two second transmission chains are respectively housed in the channel steel structures of the two limiting rods.

[0025] Compared with the prior art, the advantages of the present invention are as follows: The push rack of the end plate transfer mechanism can transfer the end plate delivered to the discharge port of the strip-shaped slideway in time under the action of the first driving device. Compared with the prior art's feeding method in which the end plate slides down by its own gravity, its transfer action is more reliable, and there will be no problem that individual end plates are difficult to effectively fall or slide in place.

[0033] The present invention will be further described in detail below in conjunction with the embodiments with reference to the drawings.

[0034] Refer to Figures 1 - 7 , an automatic feeding device for pipe pile end plates includes a storage rack 10, an end plate conveying mechanism 20 and an end plate transfer mechanism 50. The storage rack 10 is provided with a strip-shaped slideway 101, and the strip-shaped slideway 101 can be used for the end plates 1a to be vertically arranged in sequence along the length direction of the strip-shaped slideway 101, that is, the ends are stacked from back to front in the above-mentioned strip-shaped slideway 101. The front part of the strip-shaped slideway 101 has an opening, and this opening is the discharge port 100 for the end plates to move out.

[0035] Refer to Figure 2 , the strip-shaped slideway 101 of the storage rack 10 is arranged obliquely upward from back to front. Among them, the included angle between the strip-shaped slideway 101 and the horizontal plane is α. Specifically, 5° < α < 45°, and preferably, α is 15°. Arranging the strip-shaped slideway 101 obliquely upward can make the end plates placed in the strip-shaped slideway 101 tilt slightly backward, so as to avoid the end plates from tipping forward after being conveyed to the position and stopping during the conveying process, resulting in a blocking problem at the discharge port 100.

[0036] Refer to Figure 1 , in order to simplify the structure of the storage rack 10, the storage rack 10 of this embodiment includes a rectangular frame 11. The rectangular frame 11 has a limiting rod 111 that extends longitudinally and can limit the left and right sides of the end plate, and a support rod 112 that is longitudinally arranged and used to support the bottom of the end plate. Among them, the distance between the two limiting rods 111 is equal to or slightly smaller than the diameter of the corresponding end plate. The two limiting rods 111 and the support rod 112 jointly define the above-mentioned strip-shaped slideway 101.

[0037] Refer to Figure 1 , the end plate conveying mechanism 20 is arranged on the storage rack 10 and can act on the end plates 1a placed in the strip-shaped slideway 101 of the storage rack 10, so as to push the end plates to the position of the discharge port 100 of the strip-shaped slideway 101 in sequence according to the placement order.

[0038] Refer to Figure 1, the end plate conveying mechanism 20 includes a second motor 22, a transmission mechanism 30, and a pusher plate 21.

[0039] Combined with Figure 5 and Figure 7 , the pusher plate 21 is slidably disposed in the strip-shaped slideway 101 and can abut against the end plate placed at the rearmost position in the strip-shaped slideway 101. Specifically, the periphery of the pusher plate 21 in this embodiment is semi-circular arc-shaped, and its radian is basically the same as the radian of the periphery of the end plate.

[0040] See Figure 5 , the transmission mechanism 30 includes a first transmission unit located below and a second transmission unit located above. The first transmission unit corresponds to two limit rods 111 and is connected to the upper side of the pusher plate 21. The second transmission unit corresponds to the support rod 112 and is connected to the lower side of the pusher plate 21.

[0041] See Figure 5 , the first transmission unit includes a first transmission rod 31 and a first transmission chain 32. The first transmission rod 31 is disposed at the rear position of the rectangular frame 11. The first transmission rod 31 is arranged along the width direction of the strip-shaped slideway 101 and is rotatably connected to the rectangular frame 11. Specifically, both ends of the first transmission rod 31 are connected to the above-mentioned rectangular frame 11 through bearings. The first transmission rod 31 is coaxially provided with a first sprocket 33, a second sprocket 34, and a third sprocket 35. A driving sprocket 220 is provided on the power output shaft of the second motor 22, and this driving sprocket is drivingly connected to the first sprocket 33 through a chain, thereby driving the first transmission rod 31 to rotate around its own axis. The first transmission chain 32 is arranged along the length direction of the strip-shaped slideway 101. The rear end of the first transmission chain 32 is drivingly connected to the second sprocket 34 of the first transmission rod 31, and the front end of the first transmission chain 32 is drivingly connected to an auxiliary sprocket provided on the rectangular frame 11. More specifically, the first transmission chain 32 is also connected to the above-mentioned pusher plate 21 through a first connecting plate 36. Thus, when the first transmission chain 32 moves, it can drive the pusher plate 21 to move along the strip-shaped slideway 101. In this embodiment, the support rod 112 is made of channel steel structure, and the first transmission chain 32 is a double-row large roller chain with a U-shaped cover plate and is received in the notch of the channel steel. The lower part of the end plate 1a is placed on the U-shaped cover plate of the first transmission chain 32, and the rollers of the first transmission chain 32 act on the channel steel. When the first transmission chain 32 pushes the end plate 1a forward, the rollers can roll on the wall surface of the channel steel.

[0042] See Figure 5, the second transmission unit includes a second transmission rod 40 and a second transmission chain 41. The second transmission rod 40 is also disposed at the rear position of the rectangular frame 11. The second transmission rod 40 is arranged along the width direction of the strip-shaped slideway 101 and is rotatably connected to the rectangular frame 11. Specifically, both ends of the second transmission rod 40 are connected to the above-mentioned rectangular frame 11 through bearings. A fourth sprocket 42 and two fifth sprockets 43 are coaxially arranged on the second transmission rod 40. The fourth sprocket 42 is drivingly connected to the third sprocket 35 through a chain. There are two second transmission chains 41 in this embodiment, extending along the length direction of the strip-shaped slideway 101. The two second transmission chains 41 respectively correspond to the limiting rods 111 one by one, and the two second transmission chains 41 are respectively drivingly connected to the two fifth sprockets 43 on the second transmission rod 40. The two second transmission chains 41 in this embodiment are both connected to the two side portions of the push plate 21 through a second connecting plate 44. The two limiting rods 111 in this embodiment are made of channel steel structures, and the openings of the two channels are arranged opposite to each other. Correspondingly, the above two second transmission chains 41 are roller chains and are received in the channels of the channel steel.

[0043] See Figure 5 , the second motor 22 is disposed at the bottom of the rectangular frame 11. When the second motor 22 operates, it can drive the first transmission unit and the second transmission unit to operate synchronously, thereby pushing the end plate placed in the strip-shaped slideway 101 forward. This transmission method makes the movement process of the end plate in the strip-shaped slideway 101 more reliable and stable.

[0044] See Figures 1 - 3 , the end plate transfer mechanism 50 is correspondingly disposed at the front position of the storage rack 10, and specifically includes a first driving device 51 and a push rack 52. The push rack 52 is correspondingly disposed at the discharge port 100 of the strip-shaped slideway 101 for receiving the end plate coming out of the discharge port 100 of the strip-shaped slideway 101. The power output end of the first driving device 51 is connected to the push rack 52, so as to drive the end plate shifted onto the push rack 52 away from the discharge port 100 of the strip-shaped slideway 101.

[0045] See Figure 4 , in order to better utilize the structural characteristics of the circular outer peripheral edge of the end plate and simplify the structure of the end plate transfer mechanism 50, the push rack 52 is a strip-shaped rack, and this strip-shaped rack is arranged along the width direction of the strip-shaped slideway 101. The first end of the strip-shaped rack is hinged to one side of the discharge port 100 of the strip-shaped slideway 101, and the power output end of the first driving device 51 is connected to the second end of the strip-shaped rack, so as to drive the strip-shaped rack to swing up and down. During the process of the second end of the strip-shaped rack swinging upward, it is in an inclined state, and the end plate shifted onto the strip-shaped rack can roll to one side under its own gravity and away from the discharge port 100 of the strip-shaped slideway 101.

[0046] See Figure 6, the pusher 52 includes a stop plate 521, a horizontal push plate, and a limit plate 523. The stop plate 521 is vertically extended corresponding to the discharge port 100 of the strip-shaped slideway 101. The horizontal support plate 522 is formed by bending from the lower edge of the stop plate 521 towards the discharge port 100. When the strip-shaped frame moves down to the low position, the horizontal support plate 522 is flush with or lower than the edge of the discharge port 100 of the strip-shaped slideway 101. The limit plate 523 is also vertically arranged and is connected to the rear side of the horizontal support plate 522, so as to be arranged at a relatively spaced position with respect to the stop plate 521. Among them, the height position of the upper part of the limit plate 523 is lower than the height position of the upper part of the stop plate 521. Specifically, the limit plate 523 in this embodiment is located at the side position of the discharge port 100 of the strip-shaped slideway 101, so as to avoid interference with the process of the end plate in the strip-shaped slideway 101 moving to the horizontal support plate 522 of the pusher 52. The width of the horizontal support plate 522 is adapted to the thickness of one end plate. Specifically, the limit plate 523, the horizontal support plate 522, and the stop plate 521 together enclose a rolling groove 524 for only one end plate to be vertically accommodated therein. When the pusher 52 moves upward, the end plate can roll along the length direction of the rolling groove 524 and away from the discharge port 100 of the strip-shaped slideway 101. Thus, the purpose of single transfer and feeding of the end plates stacked on the pusher 52 can be achieved.

[0047] See Figure 6 , in order to enable the end plate to smoothly enter the rolling groove 524, the side edge of the limit plate 523 close to the discharge port 100 bends and extends towards the side away from the stop plate 521 to form a bent portion 525, and a guiding port 526 for guiding the end plate to enter the rolling groove 524 is formed between the bent portion 525 and the stop plate 521.

[0048] See Figure 3 and Figure 4 , the first driving device 51 of this embodiment can be selected as a first motor or a cylinder. For the sake of the flexibility of the end plate transfer action process and cost consideration, the first driving device 51 is preferably a cylinder. The cylinder body of the cylinder is rotatably connected to the storage rack 10, and the end of the piston rod of the cylinder is rotatably connected to the second end of the strip-shaped frame.

[0049] The action process of the end plate automatic feeding device for pipe piles:

[0050] After the second motor 22 is started, it drives the first transmission rod 31 and the second transmission rod 40 of the transmission mechanism 30 to synchronously transmit through a chain. At the same time, the first transmission chain 32 and the second transmission chain 41 rotate cyclically under the drive of the above two transmission rods, and drive the end plates stacked on the storage rack 10 to move forward step by step from back to front through the pusher plate 21. The end plate located at the frontmost side of the strip-shaped slideway 101 will slide onto the pusher rack 52 after shifting to the position of the discharge port 100. Then, the air cylinder acts to drive the pusher rack 52 to rotate upward. After the pusher rack 52 rotates (in an inclined state) to a certain extent, the end plate on the pusher rack 52 will, under the action of its own gravity, enter the rolling groove 524 of the pusher rack 52 and roll to one side away from the discharge port 100 of the strip-shaped slideway 101, and finally enter the riveting unit used to press-connect the end plate and the skirt plate together.

[0051] The pusher rack 52 of the end plate automatic feeding device in this embodiment can transfer the end plates delivered to the discharge port 100 of the strip-shaped slideway 101 in a timely manner under the action of the first driving device 51. Compared with the prior art feeding method in which the end plates slide down by their own gravity, its transfer action has higher reliability and there will be no problem that individual end plates are difficult to effectively fall or the sliding is not in place.
