Description

Technical Field

[0001] This utility model relates to the field of concrete pipe pile production technology, and more specifically, to a conveying device for the production of prestressed concrete pipe piles. Background Technology

[0002] Concrete pipe piles are precast concrete tubular components widely used in the foundation structures of buildings, transportation, water conservancy, and other engineering projects. They are made with cement as the binder, aggregates such as sand and gravel, and reinforced with prestressed or ordinary steel bars. The process involves centrifugal molding and steam curing, resulting in high strength and durability. Based on performance, they can be classified into prestressed concrete pipe piles (PC piles), prestressed high-strength concrete pipe piles (PHC piles), and concrete pipe piles (RC piles). PHC piles, due to their high-pressure steam curing, can achieve a strength of C80 or higher, resulting in greater load-bearing capacity and a wider range of applications.

[0003] The production and processing of concrete pipe piles requires the use of conveying devices for transportation. Currently, the main conveying devices for concrete pipe piles are trolley structures. Before each transport, workers must use hoisting equipment to move the heavy concrete pipe piles onto the trolley. The connection operation between the hoisting equipment and the concrete pipe pile is time-consuming, and the hoisting process itself affects the production efficiency of concrete pipe piles. In view of this, we propose a conveying device for the production of prestressed concrete pipe piles. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a conveying device for the production of prestressed concrete pipe piles, so as to solve the technical problem of the time-consuming process of transporting concrete pipe piles to the conveying device.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a conveying device for producing prestressed concrete pipe piles, including a conveying mechanism and a feeding and fixing mechanism provided on the conveying mechanism. The conveying mechanism includes an installation frame, which is a rectangular plate-shaped frame structure. An arc-shaped notch is provided at the front end of the installation frame. A moving wheel is provided at the lower end of the installation frame. A push-pull rod is provided at the side end of the installation frame. The feeding and fixing mechanism includes a first installation shaft and a second installation shaft. Both the first and second installation shafts are provided with two symmetrically rotatably mounted inside the installation frame. Feeding support plates are symmetrically provided on the first installation shaft, and limit clamping plates are symmetrically provided on the second installation shaft.

[0006] Preferably, a drive gear connected to the first mounting shaft is symmetrically rotatably mounted on the front end of the mounting frame, and a transmission gear is rotatably mounted between the drive gears on the front end of the mounting frame. The transmission gears mesh with each other and are respectively meshed with the drive gears.

[0007] Preferably, a drive gear is rotatably mounted at the left front end of the mounting frame, the drive gear meshes with a driving gear located on the left side, and an adjusting rod is provided at the front end shaft of the drive gear.

[0008] Preferably, a positioning rod is rotatably mounted at the end of the adjusting rod, and a limit block is provided at the side end of the push-pull rod. The limit block includes an upper block and a lower block. The positioning rod is rotatably folded between the upper block and the lower block. A buckle plate is rotatably mounted at the front end of the upper block, and a buckle block is provided at the front end of the lower block. The buckle plate is snapped onto the buckle block.

[0009] Preferably, the feeding support plate includes a first limiting part and a feeding support part in sequence along the long axis direction, with the first limiting part and the feeding support part being the axis of rotation. The first limiting part is bent upward along the long axis direction, and a circular protrusion is provided at the tail of the first limiting part. The feeding support part is bent downward in an arc shape along the long axis direction, and a ball bearing is provided at the upper end of the feeding support part. A second limiting part that bends outward in an arc shape is provided at the beginning position of the feeding support part.

[0010] Preferably, the limiting clamping plate includes, in sequence along its long axis, an installation positioning part, a first bending part, a second bending part, and a clamping limiting part. The middle position of the installation positioning part is the axis of rotation. The installation positioning part is arc-shaped. The end of the second limiting part contacts the beginning of the installation positioning part. The circular protrusion contacts the outer surface of the installation positioning part. The installation positioning part and the first bending part form a hook shape. The second bending part bends downward inward in an arc shape. The clamping limiting part bends upward in an arc shape.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the design of a feeding support plate structure, utilizes a rotatable feeding support plate and a linkage structure composed of a drive gear, transmission gear, and active gear. Only manual rotation of the adjusting rod is required to achieve synchronous rotation of the two sets of feeding support plates, allowing the concrete pipe pile to be smoothly lifted and placed on the conveying device. The entire feeding and fixing process can be completed manually by rotating the adjusting rod and operating the locking structure of the positioning rod. The lever principle makes operation labor-saving, simple, and easy to understand, requiring no professional technicians. Furthermore, the ball bearings on the feeding support plate reduce friction between the pipe pile and the support plate, making the feeding process more labor-saving, reducing manual labor intensity, and minimizing wear on the pipe pile surface. Compared to traditional feeding methods that rely on hoisting equipment, this eliminates the cumbersome steps of connecting the hoisting structure to the pipe pile and lifting it, making the feeding process more convenient, significantly shortening the feeding time for a single pipe pile, and improving production and conveying efficiency.

[0013] 2. This utility model also incorporates a feeding support plate and a limiting clamping plate structure. The feeding support plate has a first limiting part and a feeding support part arranged sequentially along its long axis, with the two parts sharing a rotation axis. The first limiting part bends upward along its long axis and has a circular protrusion at its tail. This shape allows it to contact the outer surface of the mounting and positioning part of the limiting clamping plate, precisely limiting the limiting clamping plate during the linkage process and ensuring the stability of their coordinated operation. The feeding support part bends downward in an arc shape along its long axis. This arc design matches the outer surface shape of the concrete pipe pile, increasing the contact area with the pipe pile and thus providing more stable support, preventing the pipe pile from tipping over or slipping during the support process. The circular shape of the ball bearings at the upper end of the feeding support part allows for flexible rolling, significantly reducing the friction between the pipe pile and the feeding support part during the pipe pile feeding process, thus ensuring a smoother feeding process. It is more labor-saving and reduces wear on the surface of the pipe pile, protecting the integrity of the pipe pile. The limiting clamping plate includes, along its long axis, an installation positioning part, a first bending part, a second bending part, and a clamping limiting part. The middle position of the installation positioning part is the rotation axis and is arc-shaped. The arc-shaped installation positioning part cooperates with the end of the second limiting part of the feeding support plate and the circular protrusion of the first limiting part, realizing the linkage between the two. When the feeding support plate rotates, it can drive the limiting clamping plate to rotate accordingly, ensuring the coordination of feeding and clamping actions. The clamping limiting part bends upward in an arc shape and fits tightly against the outer surface of the concrete pipe pile. When the pipe pile is lifted to the target position, the limiting clamping plate can form a stable clamp on the pipe pile from both sides. Combined with the supporting effect of the feeding support plate, it effectively prevents the pipe pile from shaking or slipping during transportation, greatly ensuring the safety and stability of the transportation process.

Detailed Implementation

[0021] like Figures 1 to 6 As shown, this utility model relates to a conveying device for the production of prestressed concrete pipe piles, including a conveying mechanism 100 and a feeding and fixing mechanism 200 provided on the conveying mechanism 100. The conveying mechanism 100 includes a mounting frame 101, which is a rectangular plate-shaped frame structure. An arc-shaped notch 1011 is provided at the front end of the mounting frame 101. A moving wheel 102 is provided at the lower end of the mounting frame 101. A push-pull rod 103 is provided at the side end of the mounting frame 101. The feeding and fixing mechanism 200 includes a first mounting shaft 201 and a second mounting shaft 202. Both the first mounting shaft 201 and the second mounting shaft 202 are provided with two symmetrically rotatably mounted in the mounting frame 101. A feeding support plate 203 is symmetrically provided on the first mounting shaft 201, and a limit clamping plate 204 is symmetrically provided on the second mounting shaft 202. This utility model uses a rotatable feeding support plate 203 in conjunction with a linkage gear structure, which allows for the smooth lifting of pipe piles by manual adjustment without the need for hoisting equipment. During the process, the ball bearings 2033 reduce friction, saving effort and protecting the pipe piles. The limiting clamping plate 204 works together to fix the piles, ensuring stable conveying, significantly shortening the feeding time, and improving conveying efficiency.

[0022] Specifically, a drive gear 104, symmetrically rotatably mounted on the front end of the mounting frame 101 and connected to the axis of the first mounting shaft 201, is rotatably mounted on the front end of the mounting frame 101 between the drive gears 104. The drive gears 105 are meshed with each other and are respectively meshed with the drive gears 104. When one of the drive gears 104 rotates, it can drive the other drive gear 104 to rotate through the drive gear 105, thereby realizing the synchronous movement of the feeding support plate 203.

[0023] Furthermore, a drive gear 106 is rotatably mounted on the left side of the front end of the mounting frame 101. The drive gear 106 meshes with the drive gear 104 located on the left side. An adjusting rod 107 is provided at the front shaft of the drive gear 106. During feeding, the device is moved to allow the concrete pipe pile to enter the mounting frame 101 through the arc-shaped notch 1011 and to position the concrete pipe pile between the feeding support plates 203. By manually rotating the adjusting rod 107, the drive gear 106 is rotated, which drives the drive gear 104 to rotate. In conjunction with the transmission gear 105, the two sets of feeding support plates 203 can rotate around the first mounting shaft 201. The rotation of the two sets of feeding support plates 203 causes the tails of the feeding support parts 2032 to move closer to each other, thereby allowing the concrete pipe pile to be fed and positioned at the upper end of the feeding support parts 2032, thus completing the feeding of the concrete pipe pile.

[0024] It is worth noting that a positioning rod 108 is rotatably mounted at the end of the adjusting rod 107, and a limit block 109 is provided on the side end of the push-pull rod 103. The limit block 109 includes an upper block 1091 and a lower block 1092. The positioning rod 108 is rotatably folded between the upper block 1091 and the lower block 1092. A buckle plate 1093 is rotatably mounted on the front end of the upper block 1091, and a buckle block 1094 is provided on the front end of the lower block 1092. The buckle plate 1093 is snapped onto the buckle block 1094. When feeding material, after the adjusting rod 107 rotates and moves by an angle, the positioning rod 108 is rotated toward the push-pull rod 103, so that the positioning rod 108 is engaged between the upper block 1091 and the lower block 1092. Then, the buckle plate 1093 is rotated to engage with the buckle block 1094, which can limit the positioning rod 108. At this time, the drive gear 106 is limited and cannot rotate on its own, so that the concrete pipe pile is always located on the feeding support plate 203.

[0025] It is worth noting that the feeding support plate 203 includes a first limiting part 2031 and a feeding support part 2032 along its long axis. The first limiting part 2031 and the feeding support part 2032 are connected by a rotation axis. The first limiting part 2031 is bent upward along its long axis and has a circular protrusion at its tail. The feeding support part 2032 is bent downward in an arc shape along its long axis and has a ball bearing 2033 at its upper end. A second limiting part 2034, which is bent outward in an arc shape, is located at the beginning of the feeding support part 2032. When the feeding support plates 203 rotate and move closer together, they can feed and support the concrete pipe pile. During the feeding process, the ball bearing 2033 can reduce friction on the concrete pipe pile and facilitate feeding.

[0026] It is worth noting that the limiting clamping plate 204 includes, along its long axis, a mounting and positioning part 2041, a first bending part 2042, a second bending part 2043, and a clamping and limiting part 2044. The mounting and positioning part 2041 has its rotation axis at its middle position and is arc-shaped. The end of the second limiting part 2044 contacts the beginning of the mounting and positioning part 2041, and the circular protrusion contacts the outer surface of the mounting and positioning part 2041. The mounting and positioning part 2041 and the first bending part 2042 form a hook shape. The second bending part 2043 bends downwards inwards in an arc shape, and the clamping and limiting part 2044 bends upwards in an arc shape. When the feeding support plate 203 rotates to feed materials, the limiting clamping plate 204 loses the limiting position of the first limiting part 2031 and will rotate due to its own weight. When the feeding support plate 203 finishes feeding materials, the limiting clamping plate 204 will also rotate to the position indicated by the first limiting part 2031. Figure 3 As shown, after the position of the feeding support plate 203 is fixed, the circular protrusion and the second limiting part 2034 can limit the limiting clamping plate 204 again to prevent it from rotating. The limiting clamping plate 204 is attached to the concrete pipe pile and can clamp and fix the concrete pipe pile in conjunction with the feeding support plate 203 to ensure the stability of the concrete pipe pile during transportation. After transportation is completed, the positioning rod 108 is released from the limit and the adjusting rod 107 is slowly rotated back. At this time, the feeding support plate 203 can slowly put the concrete pipe pile back on the ground, making the loading and unloading operation convenient.

[0027] Working Principle: This embodiment provides a conveying device for the production of prestressed concrete pipe piles. In use, the device is first moved to the side of the concrete pipe pile to be conveyed using the push-pull rod 103 and the moving wheel 102. The device position is adjusted so that the concrete pipe pile is aligned with the arc-shaped notch 1011 at the front end of the mounting frame 101. The device is then pushed to allow the concrete pipe pile to enter the mounting frame 101 through the arc-shaped notch 1011, ensuring that the concrete pipe pile is in the corresponding position between the two sets of feeding support plates 203. At this time, the feeding support portion 2032 of the feeding support plate 203 is in a relatively open state. Next, the adjustment is manually rotated... The lever 107 and adjusting lever 107 drive the drive gear 106 to rotate. The drive gear 106 meshes with the left drive gear 104, thereby driving the left drive gear 104 to rotate. The left drive gear 104 drives the right drive gear 105 to rotate through the transmission gear 105 meshing with it. The right drive gear 105 then drives the right drive gear 104 to rotate. Since the two drive gears 104 are respectively connected to the corresponding first mounting shafts 201, the two sets of first mounting shafts 201 rotate synchronously, thereby driving the two sets of feeding support plates 203 to rotate synchronously around the first mounting shafts 201. During the rotation of the feeding support plate 203, the tails of the feeding support parts 2032 gradually approach each other, and the ball bearings 2033 at the upper end of the feeding support parts 2032 contact the concrete pipe pile and reduce friction, so that the concrete pipe pile is gradually lifted under the support of the arc-shaped feeding support parts 2032. At the same time, as the feeding support plate 203 rotates, the first limiting part 2031 gradually disengages from the outer surface of the mounting and positioning part 2041 of the limiting clamping plate 204. The limiting clamping plate 204 rotates around the second mounting axis 202 under its own gravity. When the concrete pipe pile is lifted to a suitable height ( When the feeding support plate 203 is rotated to the preset position, stop rotating the adjusting rod 107. At this time, rotate the positioning rod 108 at the end of the adjusting rod 107 forward so that the positioning rod 108 is engaged between the upper block 1091 and the lower block 1092 of the side limit block 109 of the push-pull rod 103. Then rotate the buckle plate 1093 at the front end of the upper block 1091 so that it is engaged with the buckle block 1094 at the front end of the lower block 1092, thereby fixing the positioning rod 108 and restricting the rotation of the adjusting rod 107, the drive gear 106 and the drive gear 104, so as to ensure that the position of the feeding support plate 203 is fixed.At this time, under its own weight and the slight contact with the concrete pipe pile, the limiting clamping plate 204's clamping and limiting part 2044 adheres to the surface of the concrete pipe pile. The circular protrusion and the second limiting part 2034 can further limit the limiting clamping plate 204, preventing it from rotating. Combined with the support plate 203 supporting the concrete pipe pile, this achieves stable clamping of the concrete pipe pile, preventing shaking during transport, reducing friction, and preventing wear on the concrete pipe pile. Subsequently, the push-pull rod 103 and the moving wheel 102 push... The moving device transports the concrete pipe pile to the target location. Upon arrival, the latch plate 1093 is opened, causing the positioning rod 108 to disengage from the limiting block 109. The adjusting rod 107 is then slowly rotated in the opposite direction, driving the drive gear 106, drive gear 104, and transmission gear 105 to rotate in the opposite direction. This causes the feeding support plate 203 to gradually reset and open, and the tails of the feeding support parts 2032 to move away from each other. Under the action of gravity, the concrete pipe pile slowly descends with the feeding support parts 2032, and finally, the concrete pipe pile is placed stably on the ground, completing one conveying operation.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
