Description

Technical Field

[0001] The utility model relates to a production device for end plates of concrete pipe piles, in particular to a pipe pile end plate flattening device. Background Art

[0002] The end plate (or flange) is a basic component of concrete pipe piles in the industrial and construction industries. To ensure the flatness of the end plate, an overpressure wheel or a pressure rod is used to press and flatten the end plate during the production process. The existing flattening device is unreasonably arranged, which easily causes uneven force on both sides of the end plate during flattening, resulting in the end plate deviating from the preset position on the bottom plate and affecting the processing. Content of the Utility Model

[0003] According to one aspect of the utility model, a pipe pile end plate flattening device is provided, which includes a flattening frame and a flattening device. The flattening device includes:

[0005] A flattening rotation driving part fixedly arranged on the flattening frame for driving the flattening tray to rotate; and

[0007] The flattening pressure wheel of the utility model does not receive a driving force to rotate actively. The rotation of the end plate is driven by the flattening tray below it. Since the supporting surface of the flattening tray and the end plate are in surface contact, the end plate is driven to rotate through the friction force of the plane, which is more stable than the friction force generated by the linear contact between the flattening rod and the end plate in the prior art, thus preventing the situation of uneven force on the end plate and deviation from the bottom plate.

[0060] For ease of explanation, a three-dimensional XYZ rectangular coordinate system is established, where X and Y are two mutually perpendicular directions on the horizontal plane, and Z is the plumb direction. In this embodiment, the length direction of the pipe pile end plate leveling device 2 is arranged along the Y direction, and the transportation and processing direction of the end plate 10 in the pipe pile end plate leveling device 2 is also the Y direction, which may be different in other embodiments. For example, the X direction and the Y direction are swapped with those in this embodiment.

[0061] Refer to Figure 1 -2, the present utility model provides a pipe pile end plate leveling device 2, which includes a leveling frame 21, a leveling loading device 22, a leveling device 23, and an end plate flipping device 24. Among them, the leveling frame 21 is fixedly arranged on the ground. The leveling loading device 22 is used to receive the end plates on the end plate conveying line 100 and convey them to the leveling device 23. The leveling device 23 is used to level the end plates, and the end plate flipping device 24 is used to flip the leveled ends to facilitate the next process.

[0062] Refer to Figure 2-7, the rotary flat feeding device 22 includes a clamping mechanism 221, a Y-direction rotary flat feeding mechanism 222 and a Z-direction rotary flat feeding mechanism 223. The Z-direction rotary flat feeding mechanism 223 is fixedly arranged on the rotary flat frame 21, and is used to receive the end plate on the end plate conveying line 100 and drive the end plate to rise and fall in the Z direction. When it rises to the height of the clamping mechanism 221, the clamping mechanism 221 moves in the horizontal direction to clamp the end plate from the periphery of the end plate. The Y-direction rotary flat feeding mechanism 222 is used to drive the clamping mechanism 221 to move in the Y direction so as to convey the end plate into the rotary flat device 23. The clamping mechanism 221 releases the end plate to the rotary flat tray 232 in the rotary flat device 23.

[0063] See also Figure 7 The Z-direction rotary feeding mechanism 223 includes a Z-direction rotary feeding drive unit 2231 and a Z-direction rotary feeding moving frame 2232. The Z-direction rotary feeding drive unit 2231 is fixedly arranged on the rotary feeding frame 21, and the Z-direction rotary feeding moving frame 2232 is movably arranged on the rotary feeding frame 21 (can be arranged by a Z-direction guide rail), and is driven by the Z-direction rotary feeding drive unit 2231 to move along the Z direction. The bottom surface of the Z-axis rotating flat loading moving frame 2232 is provided with a penetration portion 22321, so that when the Z-axis rotating flat loading moving frame 2232 supports the end plate to rise, the clamping flange 22131a (described in detail below) of the clamping portion 22131 of the clamping mechanism 221 can pass through the penetration portion 22321 and move in the penetration portion 22321 to grab the end plate (in the case of a larger end plate, the clamping flange 22131a can also move from the periphery of the Z-axis rotating flat loading moving frame 2232 and The end plate is clamped instead of passing through the penetration portion 22321). At the same time, the setting of the penetration portion 22321 also allows the Z-axis rotary flat loading moving frame 2232 to pass through the roller on the end plate conveyor line 100 when it descends to the height of the end plate conveyor line 100, and come to a height lower than the end plate conveyor line 100, so as not to hinder the transportation of the end plate. When the end plate is transported along the end plate conveyor line 100 to the top of the Z-axis rotary flat loading moving frame 2232, the Z-axis rotary flat loading moving frame 2232 rises to hold up the end plate. Furthermore, a rotary flat loading limit block 2232 is also provided at one end of the Z-axis rotary flat loading moving frame 2232 facing the rotary flat device 23, which is used to block the end plate when it moves with the roller on the end plate conveyor line 100 to the corresponding position of the Z-axis rotary flat loading moving frame 2232, so as to prevent the end plate from continuing to move in the Y direction and thus detaching from the Z-axis rotary flat loading moving frame 2232.

[0064] See also Figure 3-5, the Y-direction rotary leveling loading mechanism 222 includes a Y-direction rotary leveling loading driving part 2221 and a Y-direction rotary leveling loading moving frame 2222. The Y-direction rotary leveling loading driving part 2221 is fixedly arranged on the rotary leveling machine frame 21. The Y-direction rotary leveling loading moving frame 2222 is movably arranged on the rotary leveling machine frame 21 (which can be arranged through a Y-direction guide rail) and is driven by the Y-direction rotary leveling loading driving part 2221 to move along the Y-direction. The clamping mechanism 221 is arranged on the Y-direction rotary leveling loading moving frame 2222 and is driven by it to move integrally along the Y-direction. Further, two rotary leveling loading push plates 22221 are also arranged at one end of the Y-direction rotary leveling loading moving frame 2222 facing the rotary leveling device 23, which are used to push the previous end plate on the rotary leveling tray 232 of the rotary leveling device 23 onto the end plate conveying line 100 when transporting the next end plate.

[0065] Refer to Figure 6 , the clamping mechanism 221 includes a clamping moving guide rail 2211, a clamping transmission part 2212, a clamping moving frame 2213, a telescopic connecting rod 2214 and a clamping driving part 2215. The clamping moving guide rail 2211 is fixedly arranged on the Y-direction rotary leveling loading moving frame 2222 along the first direction. There are two clamping moving frames 2213, which are respectively located on both sides of the clamping transmission part 2212 and are slidably arranged on the clamping moving guide rail 2211. There are two telescopic connecting rods 2214, and both ends of each are hinged to the clamping moving frame 2213 and the clamping transmission part 2212 respectively. The clamping driving part 2215 is fixedly arranged on the Y-direction rotary leveling loading moving frame 2222, and is used to drive the clamping transmission part 2212 to move along the second direction, so that the clamping transmission part 2212 drives the two clamping moving frames 2213 to move towards each other or in the opposite direction along the first direction on the clamping moving guide rail 2211 through the telescopic connecting rod 2214 to grab or release the end plate. Wherein, the first direction and the second direction are two mutually perpendicular directions located on the horizontal plane. In this embodiment, the first direction is the X-direction and the second direction is the Y-direction. This setting method saves more space. In other embodiments, it can be different. For example, the first direction is the Y-direction and the second direction is the X-direction, or the first direction and the second direction are directions inclined to the X-direction and the Y-direction on the horizontal plane, as long as the clamping moving frame 2213 can move towards the end plate and grab the end plate. In other embodiments, it is also possible not to transmit between the output end of the clamping driving part 2215 and the clamping moving frame 2213 through the clamping transmission part 2212 and the telescopic connecting rod 2214, but to make the two clamping moving frames 2213 move towards each other or in the opposite direction through other transmission methods.

[0066] The clamping moving frame 2213 is provided with a downwardly extending clamping part 22131. The main body of the clamping part 22131 is a clamping rod. The lower end of the clamping rod is formed with a clamping flange 22131a extending horizontally. When the clamping part 22131 approaches the end plate from the periphery, the end plate is supported from below by the clamping flange 22131a and thus grasped. Further, the clamping flange 22131a is set to be at the same height as the leveling tray 232 (the same height can mean exactly the same or slightly higher, as long as the action purpose can be achieved), so that when the clamping flange 22131a leaves the end plate, the end plate is released and placed on the leveling tray 232, without the need to drive the clamping flange 22131a to descend in the Z direction.

[0067] Specifically, when the Z-direction leveling loading moving frame 2232 supports the end plate and rises to a height equivalent to that of the clamping flange 22131a (the equivalent height can mean exactly the same or slightly higher, as long as the action purpose can be achieved) (and this height is also equivalent to the height of the leveling tray 232), the clamping flange 22131a passes through the penetration part 22321 of the Z-direction leveling loading moving frame 2232 or is outside the Z-direction leveling loading moving frame 2232. At this time, the clamping driving part 2215 drives the clamping moving frame 2213, thereby driving the clamping flange 22131a on the clamping part 22131 to approach the end plate in the X direction until at least part of the clamping flange 22131a comes below the end plate. The Z-direction leveling loading moving frame 2232 descends, so that the end plate is placed on the clamping flange 22131a. Multiple clamping flanges 22131a support the end plate simultaneously. The clamping rod can limit the end plate from the periphery of the end plate (without the need to squeeze and clamp the end plate radially, as long as it is in radial contact with the end plate so that the end plate will not shake randomly on the horizontal plane). When the clamping part 22131 moves in the Y direction, the clamping part 22131 can drive the end plate to move. When the Y-direction leveling loading driving part 2221 drives the clamping mechanism 221 to move in the Y direction to convey the end plate above the leveling tray 232 in the leveling device 23, the clamping part 22131 can move away from the end plate in the X direction, so that the end plate is released onto the leveling tray 232.

[0068] Furthermore, the top surface of the clamping flange 22131a is a clamping inclined surface 22131b extending outward and downward. When the clamping portion 22131 approaches the end plate from the periphery, the end plate contacts the clamping inclined surface 22131b and is supported by the clamping flange 22131a. The arrangement of the clamping inclined surface 22131b allows the end plate to move along the clamping inclined surface 22131b during the process of contacting and further approaching the clamping flange 22131a, making the contact process smoother and preventing the occurrence of a stuck situation. Two clamping portions 22131 are correspondingly arranged on each clamping mobile frame 2213, and a total of four clamping portions 22131 are respectively located at the four corners of a square or rectangle to stably support and transport the end plate. In other embodiments, the clamping portions 22131 may also be other numbers, as long as the end plate transportation can be achieved. The clamping moving frame 2213 is provided with a plurality of clamping positioning holes 22132 at different positions, and the clamping portion 22131 can be fixed in different clamping positioning holes 22132 to adapt to end plates of different specifications.

[0069] See also Figure 8 -9, the flattening device 23 includes a flattening rotation drive unit 231, a flattening tray 232, a flattening upper seat 233, a Z-axis flattening drive unit 234, a Z-axis flattening guide rail 235, a Z-axis flattening moving frame 236, a pressure wheel support 237 and a flattening pressure wheel 238. The flattening tray 232 is rotatably arranged on the flattening frame 21, and has a supporting surface 2321 for supporting the end plate. The supporting surface 2321 is used to bear and drive the end plate to rotate by friction. The supporting surface 2321 can be an annular plane or a circular plane, or other planes that can achieve at least a partial surface contact with the end plate. The flattening rotation drive unit 231 is fixedly arranged on the flattening frame 21, and is used to drive the flattening tray 232 to rotate. The flattening rotation drive unit 231 can be specifically arranged on one side of the flattening tray 232, and its lower output end is connected to the flattening tray 232 through a sprocket chain structure.

[0070] The Z-direction flattening guide rail 235 is fixedly arranged on the flattening frame 21. A flattening upper seat 233 is fixedly arranged at the top of the Z-direction flattening guide rail 235. The Z-direction flattening driving part 234 is fixedly arranged on the flattening upper seat 233, and its lower output end is fixedly connected to the Z-direction flattening moving frame 236. The press wheel support 237 is fixedly arranged below the Z-direction flattening moving frame 236. The flattening press wheel 238 is rotatably arranged on the press wheel support 237. The Z-direction flattening moving frame 236 is movably arranged on the Z-direction flattening guide rail 235 and is driven by the Z-direction flattening driving part 234 to move along the Z-direction on the Z-direction flattening guide rail 235. The flattening press wheel 238 is arranged on the Z-direction flattening moving frame 236 through the press wheel support 237 to passively rotate without power. It is driven by the Z-direction flattening moving frame 236 to press down on the end plate to flatten the end plate. Due to the frictional force between the end plate and the flattening press wheel 238, the flattening press wheel 238 is driven by the end plate to rotate passively, thus not interfering with the rotation of the end plate.

[0071] Chinese Patent CN204724642U discloses the following flattening machine: The hydraulic cylinder pushes the bottom plate upward through the output shaft, and makes the flange (i.e., the end plate) on the bottom plate closely adhere to the flattening rod, that is, the flange is tightly pressed between the bottom plate and the two flattening rods. At the same time, the motor is started to drive the flattening rod to move. Since there is frictional force between the flattening rod and the flange, and between the flange and the bottom plate, the bottom plate can rotate around the output shaft of the hydraulic cylinder. Therefore, when the flattening rod rotates around the horizontal axis, it can drive the flange to rotate around the vertical axis, and the movement between the bottom plate and the flattening rod will not interfere with each other. In this way, during the cyclic rotation of the flattening rod, the flange, and the bottom plate, the flange can be flattened. Simply put, in this flattening method, the upper flattening rod rotates actively, and drives the end plate closely attached below it and the bottom plate supporting the end plate to rotate passively through the frictional force. Moreover, the contact between the flattening rod and the end plate is a line contact, and the force is unstable. The end plate is easily taken out of the bottom plate by the flattening rod. Especially when the flatness of the end plate is low and the heights at different positions of the end plate are uneven, the end plate is prone to uneven force, resulting in the end plate deviating from the preset position on the bottom plate and affecting the processing.

[0072] In contrast, in this embodiment, the flattening press wheel 238 does not receive a driving force to rotate actively. The rotation of the end plate is driven by the flattening tray 232 below it. Since the supporting surface 2321 of the flattening tray 232 is in surface contact with the end plate, the end plate is driven to rotate through the frictional force of the plane. Compared with the prior art in which the frictional force generated by the linear contact between the flattening rod and the end plate drives the end plate to rotate, it is more stable, thus preventing the situation that the end plate is unevenly stressed and separated from the bottom plate. In addition, in this solution, since only one flattening rotation driving part 231 is required to drive the flattening tray 232 to rotate, the flattening of the end plate can be realized. Compared with the prior art in which two motors are respectively required to drive two flattening rods to rotate to realize the flattening of the end plate, the number of driving mechanisms is reduced and the cost is lowered.

[0073] In addition, in this embodiment, the flattening pressure wheel 238 presses down onto the end plate from above. Compared with the prior art where the flattening tray 232 drives the end plate to top against the flattening rod from below, since the movement of the end plate in the Z direction is reduced, with one less direction of movement for the end plate, the occurrence of accidental movement can be reduced, enabling the end plate to be flattened more smoothly.

[0074] Furthermore, there are three flattening pressure wheels 238, which are arranged at intervals of 120 degrees along the circumferential direction. Compared with the prior art where the flattening rod and the end plate are in line contact at two places, in this embodiment, the flattening pressure wheels 238 and the end plate are in line contact at three places, further increasing the force balance of the end plate and preventing the end plate from detaching from the bottom plate.

[0075] Each driving part in this specification can adopt a driving device such as a cylinder, an oil cylinder or a motor.

[0076] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several deformations and improvements can be made, or the above technical solutions can be freely combined, including freely combining the technical features between the above different embodiments, and these all belong to the protection scope of the present utility model.
