The precast pile upper surface modeling equipment comprises a rack, one or more trowelling mechanisms and one or more blunt edge modeling mechanisms. The trowelling mechanism is mounted on the rack; the blunt edge modeling mechanism is mounted on the rack, and in the working advancing direction, the blunt edge modeling mechanism is located behind the trowelling mechanism; the blunt edge modeling mechanism comprises at least one pair of blunt edge modeling assemblies with adjustable combination width in the transverse direction, and the two blunt edge modeling parts of the same pair of blunt edge modeling assemblies are oppositely arranged. A longitudinal walking mechanism is arranged at the bottom of the machine frame to drive the machine frame to move longitudinally, so that a trowelling mechanism and a blunt edge modeling mechanism on the machine frame are driven to move longitudinally, and in the moving process, the trowelling mechanism and the blunt edge modeling mechanism conduct trowelling operation and blunt edge modeling operation on the upper surface of the precast pile. Due to the fact that the combination width of the blunt-edge modeling assemblies in the same pair is adjustable in the transverse direction, the blunt-edge modeling mechanisms in the same pair can adapt to the width changes of the thick cavity section and the thin cavity section of the long mold cavity of the modeling mold in the longitudinal direction.

Description

Technical Field

[0001] This invention relates to the field of precast pile manufacturing technology, specifically to a precast pile upper surface shaping device. Background Technology

[0002] Precast piles are prefabricated in a factory using molding dies. For irregularly shaped piles (hereinafter referred to as "irregularly shaped piles"), whose cross-sectional dimensions and shapes vary along the pile length, they exhibit better pull-out resistance and bearing capacity compared to traditional precast piles with a fixed cross-section, and are increasingly favored by the construction industry. The production of variable cross-section solid precast piles requires corresponding molding dies for forming these piles. The elongated cavity of this molding die consists of at least one alternating and interconnected regular polygonal coarse cavity segment and at least one regular polygonal fine cavity segment.

[0003] The molding mold for this type of precast pile with variable cross-section includes a bottom mold and a side mold. Concrete is added into the molding mold by laying material to produce the precast pile. After laying the material, the concrete surface is usually smoothed and chamfered manually to shape the surface of the precast pile, but this operation is time-consuming and labor-intensive.

[0004] Therefore, how to reduce labor intensity and improve production efficiency in the process of shaping the surface of irregular piles is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0061] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0062] In this document, terms such as "upper," "lower," "inner," and "outer" are established based on the positional relationships shown in the accompanying drawings. Depending on the drawings, the corresponding positional relationships may also change. Therefore, they should not be interpreted as an absolute limitation on the scope of protection. Moreover, relational terms such as "first" and "second" are only used to distinguish one component from another that has the same name, and do not necessarily require or imply any such actual relationship or order between these components.

[0063] The length of a precast pile is longitudinal, the width is transverse, and the height is vertical. The working direction refers to the overall direction of movement of the shaping equipment on the upper surface of the precast pile during operation.

[0064] Example 1

[0065] See Figure 1 , 3 This embodiment provides a precast pile surface shaping device, including a frame 1, one or more smoothing mechanisms 2, and one or more blunt edge shaping mechanisms 3. The frame 1 is provided with a longitudinal traveling mechanism 9 at its bottom; the smoothing mechanism 2 is installed on the frame 1; the blunt edge shaping mechanism 3 is installed on the frame 1, and in the working travel direction, the blunt edge shaping mechanism 3 is located behind the smoothing mechanism 2; the blunt edge shaping mechanism 3 includes at least one pair of blunt edge shaping components 31 with adjustable width in the lateral direction, and the two blunt edge shaping parts of the same pair of blunt edge shaping components 31 are arranged opposite each other.

[0066] The longitudinal walking mechanism 9 drives the frame 1 to move longitudinally, thereby driving the smoothing mechanism 2 and the blunt edge shaping mechanism 3 on the frame 1 to move longitudinally. During the movement, the smoothing mechanism 2 and the blunt edge shaping mechanism 3 perform smoothing and blunt edge shaping operations on the upper surface of the precast pile. Since the width of the pair of blunt edge shaping components 31 is adjustable in the lateral direction, the pair of blunt edge shaping mechanisms 3 can adapt to the width changes of the coarse and fine cavity sections of the long mold cavity along the longitudinal direction.

[0067] In detail, the precast pile upper surface shaping equipment can be placed on one side of the mold and erected above the mold; or it can be placed above the mold by hoisting equipment such as a gantry crane when shaping the upper surface of the precast pile; or the height position of the precast pile upper surface shaping equipment can be changed by hoisting equipment when shaping the upper surface of the precast pile to adapt to the height changes of the coarse and fine cavity sections of the shaping mold cavity. The width of the pair of blunt-edged shaping components 31 is adjustable in the lateral direction. The blunt-edged shaping components 31 can be movably hinged to the frame 1, and can automatically deflect laterally to reduce the width when subjected to mold pressure, and can deflect towards the center of gravity to expand the width when not subjected to mold pressure, thereby adapting to the width changes of the coarse and fine cavity sections of the shaping mold cavity; or elastic elements, such as spring components, can be set between the pair of blunt-edged shaping components 31 to adapt to the width changes of the coarse and fine cavity sections of the shaping mold cavity by compressing the spring; or the width between the pair of blunt-edged shaping components 31 can be manually adjusted.

[0068] Of course, it is preferable that the smoothing mechanism 2 and the blunt edge shaping mechanism 3 automatically adjust their heights through a lifting mechanism to adapt to the height changes of the coarse and fine cavity sections of the shaping mold cavity. Preferably, the blunt edge shaping mechanism 3 automatically adjusts the width of the pair of blunt edge shaping components 31 through a lateral movement mechanism to adapt to the width changes of the coarse and fine cavity sections of the shaping mold cavity.

[0069] See Figure 3 The blunt-edge shaping mechanism 3 includes: a first lifting mechanism 41 with a transverse beam 43, and a transverse moving frame 51 movably mounted on the transverse beam 43 and connected at its lower end to the blunt-edge shaping component 31. The lifting timing and height of the blunt-edge shaping component 31 are set according to the specifications of the precast pile. The height of the blunt-edge shaping component 31 is automatically adjusted by the first lifting mechanism 41, improving the automation level of the precast pile upper surface shaping equipment, reducing manual operation, and increasing efficiency. Driving the transverse beam 43 to lift and controlling the lifting timing and height of the transverse beam 43 are standard settings in existing control systems and will not be elaborated here. The first lifting mechanism 41 can be a common structural type such as a scissor lift, mast lift, boom lift, sleeve cylinder lift, or truss lift, etc., without specific limitations. When the blunt edge shaping mechanism 3 is shaping the blunt edge along the length of the precast pile, the width between the pair of blunt edge shaping components 31 can be changed to adapt to the width of the shaping cavity when the width of the shaping cavity changes at the point where it travels. This can be done by adjusting the distance between the pair of horizontal moving frames 51 on which the same pair of blunt edge shaping components 31 are installed. This adjustment can be done manually or by the horizontal moving mechanism, which can be a sleeve cylinder type, guide rail type, rack and pinion type, etc.

[0070] See Figure 4The smoothing mechanism 2 includes: a second lifting mechanism 42 with a transverse beam 43, a vibratory smoother 21 located below the transverse beam 43, and a transverse moving frame 51 movably installed on the transverse beam 43 and connected to the vibratory smoother 21 at its lower end. The width of the vibratory smoother 21 is less than or equal to the minimum width of the molding cavity to avoid interference between the vibratory smoother 21 and the mold, which would prevent the vibratory smoother from smoothing the concrete in the molding cavity. The lifting timing and height of the smoothing mechanism 2 are set according to the specifications of the precast pile. The height of the smoothing mechanism 2 is automatically adjusted by the second lifting mechanism 42 to improve the automation level of the molding equipment on the upper surface of the precast pile, reduce manual operation, and improve efficiency. Driving the transverse beam 43 to lift and controlling the lifting timing and height of the transverse beam 43 are conventional settings of existing control systems and will not be described in detail here. The second lifting mechanism 42 can be a scissor lift, mast lift, boom lift, sleeve cylinder lift, or truss lift, etc., of common structural types, without specific limitations. When vibrating and smoothing the concrete inside the molding cavity, the longitudinal traveling mechanism 9 can drive the frame 1 to move back and forth longitudinally so that the vibrating smoother 21 of the smoothing mechanism 2 can fully smooth the upper surface of the concrete in the coarse or fine cavity section. Then, it moves longitudinally to the next molding cavity section. The transverse moving frame 51 can also be connected to the transverse moving mechanism, and the vibrating smoother 21 can move laterally within the molding cavity section to smooth the upper surface of the entire molding cavity section. It is possible to first vibrate and smooth one type of molding cavity section (either coarse or fine) before vibrating and smoothing the other type of molding cavity section, or to smooth them sequentially along the longitudinal direction.

[0071] Preferred, see Figure 2 The longitudinal walking mechanism 9 includes a walking wheel 91 and a walking drive 92 that drives the walking wheel 91. The walking wheel 91 is installed at the bottom of the walking beam 13 of the frame 1. The walking drive 92 drives the walking wheel 91 to rotate or move, thereby realizing the movement of the frame 1. Preferably, the upper part of the longitudinal beams on both sides of the molding mold is provided with a walking guide rail that matches the walking wheel 91, so that the movement of the frame 1 is smoother.

[0072] Preferred, see Figure 2 The walking drive 92 is electrically connected to a positioning control component, which includes a travel monitor 93 connected to the walking wheel 91. The travel monitor 93 is electrically connected to the controller 8 of the upper surface molding equipment. The controller 8 controls the walking drive 92 to stop or decelerate according to the signal sent by the travel monitor 93. By monitoring the travel distance of the walking wheel 91 through the travel monitor 93, the longitudinal movement distance of the frame 1 can be monitored. In this way, the deceleration position and the stopping position can be set according to the specifications of the precast pile, thereby improving the automation level of the precast pile upper surface molding equipment. The travel monitor 93 can be an encoder or other monitor that can monitor the movement distance of the walking wheel 91, without specific limitations.

[0073] Preferred, see Figure 2 The frame 1 is equipped with a cleaning component 12 at least at the front end in the direction of travel. Preferably, the frame 1 is equipped with cleaning components 12 at both the front and rear ends. The cleaning components 12 clean up the debris in front of and behind the traveling wheels 91, thus avoiding affecting the movement of the frame 1. Preferably, the cleaning components 12 are inclined relative to the traveling beam 13, so that the debris is guided outward and cleaned outside the travel path of the traveling wheels 91 during cleaning.

[0074] Preferably, the frame 1 is a lifting frame 1, which can drive the smoothing mechanism 2 and the blunt edge shaping mechanism 3 to lift as a whole, thereby improving applicability and convenience.

[0075] Example 2

[0076] In this embodiment, the parts that are the same as in Embodiment 1 are given the same reference numerals, and the same text descriptions are omitted.

[0077] See Figure 1-8 Compared to Embodiment 1, the precast pile upper surface shaping device provided in this embodiment has the following structural design differences:

[0078] See Figure 5 The blunt edge shaping component 31 includes a rollable chamfering shaping roller 311, with the shaping surfaces of the two chamfering shaping rollers 311 facing each other. The processing surface of the chamfering shaping roller 311 in contact with the concrete is adapted to the blunt edge shape of the precast pile to be shaped. The width of the coarse and fine cavity sections of the shaping mold cavity can be adapted by adjusting the pair of chamfering shaping rollers 311.

[0079] Preferred, see Figure 5 The blunt-edge shaping component 31 also includes a chamfering scraper 312 hinged to the transverse frame 51 and with its working part located behind the chamfering shaping roller 311. In the working direction, after the chamfering shaping roller 311 performs the blunt-edge shaping, the chamfering scraper 312 scrapes away excess concrete material. The two chamfering scrapers 312 in the same pair of blunt-edge shaping components 31 at least partially overlap longitudinally, and the chamfering surfaces of the two chamfering scrapers 312 in the same pair of blunt-edge shaping components 31 are arranged facing each other. This ensures that after adjusting the width of the same pair of blunt-edge shaping components 31, the working width of the same pair of chamfering scrapers 312 is the same as the width of the shaping mold cavity, avoiding gaps between the same pair of chamfering scrapers 312 after widening the width between the same pair of blunt-edge shaping components 31. The chamfering surfaces are adapted to the blunt-edge shape of the precast pile to be shaped.

[0080] Preferred, see Figure 5 A first elastic element 313 is provided between the transverse frame 51 and the chamfered scraper 312. The first elastic element 313 is located below the hinge position between the transverse frame 51 and the chamfered scraper 312.

[0081] Preferred, see Figure 5 The chamfering scraper 312 includes a mounting plate hinged to the transverse frame 51 and a chamfering working plate mounted on the mounting plate. The chamfering working plate is made of wear-resistant material, which reduces the frequency of damage and replacement of the chamfering scraper 312. It also allows the chamfering working plate to be replaced only when making precast piles of different specifications, reducing the difficulty of replacement and improving the efficiency of replacement.

[0082] Preferred, see Figure 5 The chamfered scraper 312 is equipped with abutting members 314 that abut against the transverse frame 51 to prevent the chamfered scraper 312 from tilting excessively in the working direction due to the tension of the first elastic member 313. More preferably, the abutting members 314 are located on both sides of the hinge position between the chamfered scraper 312 and the transverse frame 51. More preferably, in the pair of chamfered scrapers 312 of the same blunt edge shaping assembly 31, in the working direction, the rear chamfered scraper 312 has a clearance hole 3121 to avoid the abutting member on the front chamfered scraper 312.

[0083] Example 3

[0084] In this embodiment, the parts that are the same as in Embodiments 1 and 2 are given the same reference numerals, and the same text descriptions are omitted.

[0085] See Figure 1-8 Compared to Embodiments 1 and 2, the precast pile upper surface shaping device provided in this embodiment has the following structural design differences:

[0086] See Figure 6 The vibratory trowel 21 includes a trowel plate 211 and a vibrator 212 disposed on the trowel plate 211. The vibration of the vibrator 212 drives the trowel plate 211 to vibrate, thereby realizing the vibration and troweling of the concrete on the upper surface of the precast pile.

[0087] Preferred, see Figure 6 The trowel 211 includes a trowel base plate 2111 and a trowel side plate 2112 that is inclined upward from the trowel base plate 2111. The trowel side plate 2112 can shape the connection between the coarse cavity section and the fine cavity section of the molding cavity into a transition slope, so that the bottom mold and the side mold can have a transition cavity section. When the vibrating trowel 21 is located on the upper surface of the fine cavity section of the molding cavity to vibrate and trowel the concrete, when it moves to both ends of the fine cavity section, it can vibrate and trowel the concrete on the upper surface of the transition cavity section. Having a transition section makes it easier for the precast pile to be removed from the mold and is also more aesthetically pleasing.

[0088] Preferred, see Figure 6 A shock absorber 22 is provided between the transverse frame 51 and the vibratory trowel 21 to prevent the transverse frame 51 from being affected by the vibration of the vibratory trowel 21.

[0089] Example 4

[0090] In this embodiment, the parts that are the same as in Embodiments 1, 2, and 3 are given the same reference numerals, and the same text descriptions are omitted.

[0091] See Figure 1-8 Compared to embodiments one, two, and three, the precast pile upper surface shaping device provided in this embodiment has the following structural design differences:

[0092] See Figure 3-6 The transverse frame 51 has a vertical mounting arm 511, and the vertical mounting arm 511 is hinged to a transverse swing assembly 6. The transverse swing assembly 6 includes a lower hinge seat 61, an upper hinge seat 62, and a swing arm 63 with its two ends respectively hinged to the upper hinge seat 62 and the lower hinge seat 61. The transverse ends of the upper hinge seat 62 and the transverse ends of the lower hinge seat 61 are respectively hinged to a vertical swing arm 63. The upper hinge 62 is hinged to the mounting arm 511. The swing arm 63 can rotate relative to the upper hinge 62 and the lower hinge 61. By setting the lateral swing component 6, the smoothing mechanism 2 and the blunt edge shaping mechanism 3 mounted on the lower hinge 61 can push the lower hinge 61 to move laterally when subjected to lateral thrust, thereby causing the swing arm 63 to rotate. This changes the lateral position and vertical height of the smoothing mechanism 2 and the blunt edge shaping mechanism 3. When there is an error in the placement of the mold, an error in the width of the shaping mold cavity, or a change in the width of the coarse and fine sections of the shaping mold cavity, the reverse thrust between the mold and the smoothing mechanism 2 or the blunt edge shaping mechanism 3, or the thrust applied manually to the smoothing mechanism 2 and the blunt edge shaping mechanism 3, can be laterally adjusted to adapt to the position and width of the shaping mold cavity. In other words, the lateral swing component 6 enables the smoothing mechanism 2 and the blunt edge shaping mechanism 3 to make fine adjustments to adapt to errors and to adapt to changes in the width of the coarse and fine sections. In addition, the vibratory trowel 21 vibrates vertically when it is working, and the lateral swing component 6 can swing laterally to adapt to the height difference caused by the vibration of the vibratory trowel 21.

[0093] Preferred, see Figure 3-6 At least one of the upper hinge seat 62 and the lower hinge seat 61 is connected to the swing amplitude adjustment mechanism 64, which controls the range of lateral swing of the smoothing mechanism 2 and the blunt edge shaping mechanism 3 to avoid excessive swing.

[0094] Preferred, see Figure 5 , 6 The swing adjustment mechanism 64 includes a limiting baffle 641 and an adjusting bolt 642. The limiting baffle 641 is installed at the lower middle of the upper hinge seat 62, and the adjusting bolt 642 is installed on the swing arm 63, with the end face of the adjusting bolt 642 facing the limiting baffle 641. The distance between the adjusting bolt 642 and the limiting baffle 641 is the allowable lateral swing range of the lower hinge seat 61, that is, the range in which the smoothing mechanism 2 and the blunt edge shaping mechanism 3 can swing laterally.

[0095] Preferred, see Figure 5 , 6 The lateral swing assembly 6 also includes a second elastic element 65 connected to the upper hinge seat 62 and one of the swing arms 63 at both ends. The second elastic element 65 swings the swing arm 63 back in the opposite direction to its swing direction, thus providing a restoring force to the swing arm 63 and the lower hinge seat 61, ensuring that the smoothing mechanism 2 and the blunt edge shaping mechanism 3 always have a swinging tendency force to abut against the mold. More preferably, the second elastic element 65 is inclined relative to the swing arm 63. The second elastic elements 65 on the two lateral swing assemblies 6 connected to the blunt edge shaping assembly 31 are in opposite directions, and each blunt edge shaping assembly 31 has a swinging tendency force in the direction away from the shaping mold cavity axis to abut against the two side molds of the mold respectively. By setting the second elastic element 65, the smoothing mechanism 2 and the blunt edge shaping mechanism 3 can work more closely to the mold, more effectively achieving the shaping of the upper surface of the precast pile; the lateral swing assembly 6 equipped with the vibratory smoother 21 can have a second elastic element 65 connected to the upper hinge seat 62 on both sides of the swing arm 63. In addition, by providing a second elastic element 65, the swing arm 63 can be prevented from swinging easily with the upper hinge seat 62 and the lower hinge seat 61. The second elastic element 65 plays a certain limiting role.

[0096] Preferred, see Figure 5 , 6The lateral swing assembly 6 is located at the bottom or middle of the vertical mounting arm 511, and is hinged to the mounting arm 511 via a lateral pivot 662, facilitating the longitudinal swing of the lateral swing assembly 6. That is, the lateral swing assembly 6 itself can swing laterally, and it can also swing longitudinally relative to the vertical mounting arm 511. In other words, the lateral swing assembly 6 enables the smoothing mechanism 2 and the blunt edge shaping mechanism 3 to swing both laterally and longitudinally. More preferably, the lateral swing assembly 6 is provided with a first hinge seat 66 that is laterally hinged to the mounting arm 511, allowing the lateral swing assembly 6 to deflect longitudinally relative to the mounting arm 511. The first hinge seat 66 is provided with a deflection limiting member 661 that longitudinally abuts against one side of the mounting arm 511, thereby limiting the lateral swing assembly 6 to swing only longitudinally relative to the vertical mounting arm 511. Specifically, the deflection limiting member 661 of the transverse swing assembly 6 connected to the vibratory trowel 21 is located on the back side of the working direction of travel. That is, the vibratory trowel 21 can only deflect relative to the vertical mounting arm 511 in the working direction of travel. In other words, when the vibratory trowel 21 moves in the working direction of travel for vibratory troweling, the vibratory trowel 21 will not deflect longitudinally. When the vibratory trowel 21 moves in the opposite direction of travel for vibratory troweling, the vibratory trowel 21 will deflect longitudinally. Preferably, during the vibratory troweling operation, the vibratory trowel 21 first moves in the opposite direction of travel, causing the vibratory trowel 21 to tilt and lift longitudinally. Excess concrete is located under the tilted trowel base plate 2111 due to vibration. When the vibratory trowel 21 moves in the working direction of travel for vibratory troweling, it will press down on the piled concrete due to its own weight, thus enhancing the vibration compaction effect. The deflection limiting member 661 of the lateral swing component 6 connected to the blunt ridge shaping component 31 is located in front of the working direction of travel. That is, the blunt ridge shaping component 31 can only deflect relative to the vertical mounting arm 511 in the opposite direction of the working direction of travel. In other words, when the blunt ridge shaping component 31 moves in the working direction of travel to perform blunt ridge shaping, the blunt ridge shaping component 31 will deflect longitudinally. Preferably, when the blunt ridge shaping mechanism 3 is working, the lateral beam 43 of the first lifting mechanism 41 descends until the blunt ridge shaping component 31 deflects relative to the mounting arm 511, so that when moving in the working direction of travel, the blunt ridge shaping component 31 will press against the concrete surface of the precast pile due to gravity, thereby enhancing the blunt ridge shaping effect.

[0097] Example 5

[0098] In this embodiment, the parts that are the same as those in Embodiments 1, 2, 3, and 4 are given the same reference numerals, and the same text descriptions are omitted.

[0099] See Figures 1-8 Compared to embodiments one, two, three, and four, the precast pile upper surface shaping device provided in this embodiment has the following structural design differences:

[0100] See Figure 3 , 48. The transverse frame 51 is connected to a transverse drive 53 that can drive the transverse frame 51 to move laterally along the transverse beam 43. The transverse drive 53 includes a transverse guide 531 that is transversely arranged on the transverse beam 43 and a transverse motor 532 that drives the transverse frame 51 to move laterally along the transverse guide 531. The transverse motor 532 is mounted on the transverse frame 51. The transverse guide 531 is preferably a rack to improve the transverse accuracy. The transverse frame 51 moves laterally along the rack by rotating the gear of the transverse motor 532.

[0101] Preferred, see Figure 8 The two transverse sliding frames 51, each equipped with a pair of blunt-edged prism shaped components 31, are considered a pair of transverse sliding frames 51. The left transverse sliding frame 51 in each pair is connected laterally by a connecting component 52, and the right transverse sliding frame 51 is connected laterally by another connecting component 52. When one of the left transverse sliding frames 51 in each pair moves, the other transverse sliding frames 51 on the left also move. That is, when the spacing between one pair of transverse sliding frames 51 is changed to change the lateral width of the pair of blunt-edged prism shaped components 31, the spacing between the other pairs of transverse sliding frames 51 will also change. In other words, the lateral width of multiple pairs of blunt-edged prism shaped components 31 can be changed simultaneously in one operation. Since precast piles are usually mass-produced with the same specifications, setting the connecting component 52 to connect one of the pairs of transverse sliding frames 51 can improve the operation efficiency when changing the lateral width of the pair of blunt-edged prism shaped components 31.

[0102] Preferred, see Figure 8 The connecting component 52 includes a connecting seat 521 disposed on the transverse frame 51, a connecting rod 522 through which two or more connecting seats 521 pass, and a connecting pin 523 that fixes the connection position between the connecting seat 521 and the connecting rod 522. The connecting rod 522 is provided with multiple connecting holes for the connecting pin 523 to connect to, so that when the transverse frame 51 is initially installed and fixed on the connecting rod 522, the corresponding connecting hole position can be selected according to the actual specifications of the precast pile, so that the transverse frame 51 only needs to be slightly adjusted laterally to adapt to the width changes of the coarse and fine cavity sections of the molding cavity.

[0103] See Figure 4 The transverse beam 43 is preferably configured with two sets of transverse frames 51 on which vibratory levelers 21 are installed. The transverse frames 51 on the left side of the transverse beam 43 and the transverse frames 51 on the right side of the transverse beam 43 are each connected by a connecting component 52. One transverse frame 51 on the left side and one transverse frame 51 on the right side are connected to a transverse drive 53. Alternatively, all transverse frames 51 can be configured as a group and connected by a connecting rod 522. One transverse frame 51 can be connected to a transverse drive 53. That is, the transverse motor 532 is installed on one of the transverse frames 51. This is not specifically limited and can be set according to the actual transverse width.

[0104] See Figure 3 The multiple pairs of transverse moving frames 51 mounted on the transverse beam 43 are preferably configured as two sets. Among the multiple pairs of transverse moving frames 51 on the left side of the transverse beam 43 and the multiple pairs of transverse moving frames 51 on the right side of the transverse beam 43, each pair of transverse moving frames 51 is connected to a transverse moving drive 53, and each pair of transverse moving frames 51 is equipped with a transverse moving motor 532. Of course, it can also be configured as one or more sets, without specific limitation, and is set according to the actual transverse width.

[0105] Preferred, see Figure 3 The transverse beam 43 is provided with anti-collision parts 7 at both ends in the transverse direction; and / or, the transverse frame 51 is provided with anti-collision parts 7 on both sides; to prevent the transverse frame 51 from being damaged by collision during transverse movement.

[0106] Preferred, see Figure 8 The transverse frame 51 includes a movable frame 512 sleeved on the transverse beam 43. An auxiliary roller 513 is provided on the inner side of the movable frame 512 to abut against the transverse beam 43, thereby reducing the friction between the movable frame 512 and the transverse beam 43.

[0107] Preferred, see Figure 7 , 8 The transverse drive 53 is electrically connected to a transverse control component, which includes a transverse induction switch 54. The transverse induction switch 54 is mounted on the transverse beam 43 and is electrically connected to the controller 8 of the upper surface shaping equipment. When the transverse frame 51 touches the transverse induction switch 54, the transverse induction switch 54 sends a signal to the controller 8. The controller 8 controls the transverse drive 53 to stop or decelerate. Preferably, two transverse induction switches 54 are provided on one side of the transverse beam 43, one for deceleration and one for stopping. During the transverse movement of the transverse frame 51, the deceleration transverse induction switch 54 is touched first, and the controller 8 controls the transverse drive 53 to decelerate so that the transverse frame 51 decelerates. Then, the stop transverse induction switch 54 is touched, and the controller 8 controls the transverse drive 53 to stop driving so that the transverse frame 51 stops moving. The lateral movement of the transverse frame 51 is controlled by the transverse movement control component, thereby adjusting the lateral position of the smoothing mechanism 2 and the blunt edge shaping mechanism 3, as well as adjusting the lateral width between the same pair of blunt edge shaping components 31, thereby improving the automation level of the precast pile upper surface shaping equipment.

[0108] Example 6

[0109] In this embodiment, the parts that are the same as those in Embodiments 1, 2, 3, 4, and 5 are given the same reference numerals, and the same text descriptions are omitted.

[0110] See Figures 1-8 Compared to embodiments one, two, three, four, and five, the precast pile upper surface shaping device provided in this embodiment has the following structural design differences:

[0111] See Figure 3 , 4 The transverse beam 43 is connected to a lifting drive 44 capable of moving the transverse beam 43 vertically. The lifting drive 44 includes a motor mounted on the frame 1 and a screw jack connecting the motor and the transverse beam 43. Preferably, a hinge assembly 45 is provided between the transverse beam 43 and the lifting drive 44. By providing the hinge assembly 45, the transverse beam 43 can adapt to the height difference on both sides of the transverse beam, avoiding jamming caused by different lifting rates on both sides of the transverse beam 43. More preferably, the hinge assembly 45 includes a first hinge 451 connected to the transverse beam 43 and a second hinge 452 connected to the lifting drive 44, with the first hinge 451 and the second hinge 452 hinged together; or the transverse beam 43 is provided with a second hinge seat, and the lifting screw of the lifting drive 44 is longitudinally hinged to the second hinge seat.

[0112] Preferred, see Figure 7 , 8 The lifting drive 44 is electrically connected to a lifting control component, which includes a lifting induction switch 46 and an induction plate 47. The lifting induction switch 46 is installed on the frame 1 and electrically connected to the controller 8 of the upper surface shaping equipment. The induction plate 47 is installed on the transverse beam 43. When the induction plate 47 triggers the lifting induction switch 46 during the lifting of the transverse beam 43, the lifting induction switch 46 sends a signal to the controller 8, and the controller 8 controls the lifting drive 44 to stop or decelerate. The preferred frame 1 has two stop lifting sensor switches 46 installed vertically, with a deceleration lifting sensor switch 46 located between the two stop lifting sensor switches 46. During the upward movement of the transverse beam 43, the sensor plate 47 first triggers the deceleration lifting sensor switch 46, and the controller 8 controls the lifting drive 44 to decelerate, thereby slowing down the transverse beam 43. The sensor plate 47 then triggers the stop lifting sensor switch 46, and the controller 8 controls the lifting drive 44 to stop driving, thereby stopping the transverse beam 43, which returns to its original position and stops rising. During the downward movement of the transverse beam 43, the sensor plate 47 first triggers the deceleration lifting sensor switch 46, and the controller 8 controls the lifting drive 44 to decelerate, thereby slowing down the transverse beam 43. The sensor plate 47 then triggers the stop lifting sensor switch 46, and the controller 8 controls the lifting drive 44 to stop driving, thereby stopping the transverse beam 43, which descends to its lowest position.

[0113] See Figure 1-8 In general, the precast pile surface shaping equipment includes a frame 1, a smoothing mechanism 2, and a blunt edge shaping mechanism 3. The smoothing mechanism 2 vibrates and smooths the surface of the precast pile, and the blunt edge shaping mechanism 3 gives the surface of the precast pile a blunt edge shape. Usually, after the smoothing mechanism 2 vibrates and smooths for 15-20 minutes, the blunt edge shaping mechanism 3 performs the blunt edge shaping. Of course, the interval time is set according to the characteristics of the concrete material and the actual situation, and is not specifically limited.

[0114] The blunt edge shaping mechanism 3 includes a first lifting mechanism 41, a transverse frame 51 installed on the transverse beam 43, and a transverse swing component 6 installed on the transverse frame 51 and connected to the blunt edge shaping component 31. The blunt edge shaping component 31 includes a chamfering shaping roller 311 and a chamfering scraper 312. The transverse frame 51 is connected to a transverse drive 53. The first lifting mechanism 41 drives the blunt edge shaping component 31 to lift and lower the corresponding coarse cavity section and fine cavity section working position. The transverse drive 53 drives the same pair of blunt edge shaping components 31 to move laterally, changing the transverse width between the same pair of blunt edge shaping components 31 to adapt to the width changes of the coarse cavity section and fine cavity section of the long mold cavity of the shaping mold along the longitudinal direction. The transverse swing component 6 enables the same pair of blunt edge shaping components 31 to adapt to mold errors and changes in the width of the shaping mold cavity. The longitudinal travel mechanism 9 drives the frame 1 and the blunt edge shaping mechanism 3 on the frame 1 to move in the working direction so that the upper surface of the precast pile has a blunt edge shape.

[0115] The smoothing mechanism 2 includes a second lifting mechanism 42, a transverse frame 51 installed on the transverse beam 43, and a transverse swing component 6 installed on the transverse frame 51 and connected to the vibratory smoother 21. The transverse frame 51 is connected to a transverse drive 53. The second lifting mechanism 42 drives the blunt edge shaping component 31 to lift and lower the corresponding coarse cavity section and fine cavity section working position. The transverse drive 53 drives the vibratory smoother 21 to move laterally to smooth the concrete surface in the transverse direction. The transverse swing component 6 enables the vibratory smoother 21 to adapt to mold errors and height changes caused by vibration. The longitudinal travel mechanism 9 drives the frame 1 and the smoothing mechanism 2 on the frame 1 to move back and forth in the longitudinal direction to vibrate and smooth the surface of the precast pile.

Any improvements and modifications made by those skilled in the art without departing from the spirit and scope of the present invention shall also be considered as within the scope of protection of the present invention.
