Description

Technical Field

[0002] In the process of concrete component production, it involves injecting concrete into a mold. To improve production efficiency and reduce costs, usually, the discharge port of the cloth hopper is aligned with the mold cavity of the mold, and the cloth hopper moves along the length direction of the mold to distribute the cloth into the mold cavity. Currently, usually, after the cloth hopper fills the entire depth of the mold cavity with material at one time, the concrete in the mold cavity is vibrated and compacted. There are some problems with this cloth vibrating method. It is difficult to ensure the accuracy of the cloth quantity through one-time cloth distribution, and it is easy to have too much or too little cloth. Manual operations are required to remove excess raw materials or replenish materials. This not only has low cloth distribution efficiency and poor cloth distribution accuracy, but also has high labor costs. In addition, there is also the problem that the concrete cannot be fully vibrated and compacted, affecting the forming quality of precast components. Summary of the Invention

Detailed implementation manners

[0031] In order to enable those skilled in the art of the present technology to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0032] In this article, terms such as "upper, lower, inner, outer" are established based on the positional relationship shown in the drawings. Depending on the different drawings, the corresponding positional relationship may also change accordingly. Therefore, it cannot be understood as an absolute limitation of the protection scope; moreover, relational terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0033] As Figure 1-12As shown in the figure, the present invention provides a method for concrete placing and vibrating in the production of precast piles by die arranging, which includes using a placing and vibrating integrated machine to carry out layered placing and pouring and layered vibration on two or more precast pile molds arranged side by side. Among them, the placing and vibrating integrated machine includes a frame 100 that can move back and forth along the length direction of the precast pile mold, a placing hopper 200 and a vibrator 300 arranged along the length direction of the precast pile mold on the frame 100, and a controller 400 for controlling the operation of the frame 100, the placing hopper 200, and the vibrator 300. For the convenience of description and understanding, the length direction of the precast pile mold is defined as "longitudinal", the width direction of the precast pile mold is defined as "transverse", and the depth direction of the precast pile mold is defined as "vertical".

[0034] The controller 400 presetly divides the precast pile mold into N (N≥2) working sections along the length direction and M (M≥2) working layers along the depth direction. The controller 400 instructs the frame 100 to run to the X (X≤N) working section, instructs the placing hopper 200 to carry out placing and pouring on the Y working layer (1≤Y) of this working section, and instructs the vibrator 300 to vibrate the Y working layer of the X-1 (X-1≥1) working section; when the placing and pouring and vibration of the Y working layer are completed for N working sections, the placing and vibrating integrated machine repeats the placing and pouring and vibration of the Y+1 (Y+1≤M) working layer until the end.

[0035] As Figure 13 shown in the figure, after placing and pouring and vibrating the previous working layer, then carrying out placing and pouring and vibration on the next working layer, using one specification of vibrator 300 can meet the vibration requirements for each working layer. The method of layered placing and layered vibration ensures the accuracy of the placing volume and that each working layer can be fully vibrated, improving the forming quality of the precast pile. And the placing and vibrating integrated machine can carry out layered placing and pouring and layered vibration on two or more precast pile molds, improving the production efficiency. For the convenience of understanding, assume that the direction from the 1st working section to the Nth (N≥2) working section is defined as the positive direction along the length direction, and the direction from the Nth working section to the 1st working section is defined as the negative direction along the length direction. When the placing and vibrating integrated machine moves forward and sequentially carries out placing and pouring and vibration on the 1st working layer from the 1st working section to the Nth working section, and then the placing and vibrating integrated machine moves backward and sequentially carries out placing and pouring and vibration on the 2nd working layer from the Nth working section to the 1st working section. According to the value of M, it is determined whether the placing and vibrating integrated machine needs to continue to repeat the above positive and negative alternating movement for layered placing and pouring and vibration until the placing and vibrating integrated machine completes the layered placing and pouring and layered vibration of the precast pile mold.

[0036] As Figure 2As shown in the figure, the cloth vibrating and pouring machine includes a longitudinal displacement sensor 103 disposed on the frame 100 and electrically connected to the controller 400. The longitudinal displacement sensor 103 is used to monitor the position change of the frame 100 in real time to determine whether the frame 100 has moved to the specified working section. When the longitudinal displacement sensor 103 transmits the information that the frame 100 has moved to the X working section to the controller 400, the controller 400 instructs the hopper 200 to pour concrete on the Y working layer of the X working section, and at the same time instructs the vibrator 300 to vibrate the Y working layer of the X-1 working section.

[0037] As Figure 2 shown in the figure, there are two vibrators 300 located on both sides of the hopper 200 along the length direction of the precast pile mold. When the frame 100 moves forward, the controller 400 instructs one of the vibrators 300 (i.e., the vibrator 300 on the left side of the hopper 200) to vibrate the Y working layer. When the frame 100 moves in the reverse direction, the controller 400 instructs the other vibrator 300 (i.e., the vibrator 300 on the right side of the hopper 200) to vibrate the Y+1 working layer, which is beneficial to improving production efficiency and avoiding the situation where the vibrator 300 needs to move forward to the working section to vibrate when the Y+1 working layer of the working section needs to be vibrated.

[0038] As Figure 2 、 4 、5 shown, the cloth vibrating and pouring machine further includes a lateral displacement sensor 8 disposed on the hopper 200 and electrically connected to the controller 400. The frame 100 includes a first frame body 10a that reciprocates along the length direction of the precast pile mold and a second frame body 10b that can reciprocate laterally along the first frame body 10a. The hopper 200 and the vibrator 300 are disposed on the second frame body 10b along the length direction of the precast pile mold. The lateral displacement sensor 8 is used to detect the position change of the hopper 200 moving laterally along the first frame body 10a to determine whether the hopper 200 has reached the specified working section. When the lateral displacement sensor 8 transmits the information that the hopper 200 has moved laterally to the X working section of the precast pile mold to be poured with concrete to the controller 400, the controller 400 instructs the hopper 200 to pour concrete on the Y working layer of the X working section.

[0039] As Figure 4 、 5 shown in the figure, the hopper 200 is provided with a first distance measuring member 7 electrically connected to the controller 400. Before the concrete pouring, the first distance measuring member 7 transmits the information of the entire depth H of the cavity of the precast pile mold collected to the controller 400. Before pouring concrete on the Y+1 working layer, the first distance measuring member 7 transmits the information of the depth h of the concrete in the cavity after pouring concrete on the Y working layer to the controller 400, and instructs the hopper 200 to pour concrete with a depth of h Y+1 for the Y+1 working layer, where h Y+1=(H - h) / (M - Y). The first distance measuring member 7 can be a laser displacement sensor, and the first distance measuring member 7 can be arranged at the bottom of the hopper body 1.

[0040] As Figure 12 shown, the vibrator 300 is provided with a second distance measuring member 316 electrically connected to the controller 400. The vibrator 300 includes a vibrating member 310 and a lifting driving member for driving the vibrating member 310 to move vertically. The second distance measuring member 316 is used to detect the descending position of the vibrating member 310 to determine whether the lower end of the vibrating member 310 is inserted into a predetermined depth range. The second distance measuring member 316 can be a laser displacement sensor, and the second distance measuring member 316 can be arranged at the top of the lifting bracket 311 or the vibrating rod 3142. During the vibration of the concrete in the Y + 1 working layer, the second distance measuring member 316 will detect the information of the depth position where the lower end of the vibrating member 310 is inserted into the Y working layer within 0.1h Y+1 -0.25h Y+1 and transmit it to the controller 400, and instruct the vibrator 300 to vibrate the Y + 1 working layer, where h Y+1 is the placing depth of the Y + 1 working layer. As Figure 13 (1) shown, after placing the concrete in the 1st working layer of the working section, the lower end of the vibrating member 310 is inserted into a predetermined depth within the placed concrete in the 1st working layer, and the predetermined depth is about 0.9 times the placing depth of the 1st working layer, so as to fully vibrate the 1st working layer. As Figure 13 (2) shown, after placing the concrete in the 2nd working layer of the working section, the lower end of the vibrating member 310 is inserted into the depth position of 0.1h2 - 0.25h2 within the 1st working layer, so as to fully vibrate the 2nd working layer. As Figure 13 (3) shown, after placing the concrete in the 3rd working layer of the working section, the lower end of the vibrating member 310 is inserted into the depth position of 0.1h3 - 0.25h3 within the 2nd working layer, so as to fully vibrate the 3rd working layer. When the vibration requirements are met, the depth range where the lower end of the vibrating member 310 is inserted into the Y working layer can be less than 0.1h Y+1 or greater than 0.25h Y+1 .

[0041] The controller 400 calculates that the precast pile mold is divided into N (N≥2) working sections along the length direction according to the length of the cavity of the precast pile mold, the placing width of the placing hopper 200, and the vibrating width of the vibrator 300 (the above parameters are pre - input into the controller 400). The controller 400 calculates that the precast pile mold is divided into M (M≥2) working layers along the depth direction according to the placing depth of the placing hopper 200, the vibrating depth of the vibrator 300, and the cavity depth H (wherein, the cavity depth H can be pre - input into the controller 400, or before the concrete placing, when the placing hopper 200 moves to the working section to be placed and concreted, the first distance measuring member 7 detects the cavity depth of this working section and sends it to the controller 400).

[0042] As Figure 2 shown in 3 Figures 1-9, the cloth hopper 200 includes a hopper body 1 installed on the frame 100. The top of the hopper body 1 is open, and at least one discharge port 12 is provided at the bottom. A movable door 2 that can open or completely close the discharge port 12 and a deflectable material guide plate 4 are provided at the bottom of the hopper body 1. The material guide plate 4 and the movable door 2 are located on both sides of the discharge port 12, and the movable door 2 is located above the material guide plate 4. The hopper body 1 is also provided with a first driving member 3 for driving the opening and closing of the movable door 2 and a second driving member 5 for driving the material guide plate 4. The first driving member 3 and the second driving member 5 are electrically connected to the controller 400. The concrete material in the hopper body 1 enters the mold cavity of the precast pile mold under the guidance of the material guide plate 4, precisely controlling the cloth angle to achieve precise cloth for the operation area, avoiding problems such as excessive or insufficient cloth in some areas and the concrete material being easily poured outside the mold cavity, and improving the cloth efficiency. The deflection angle of the material guide plate 4 relative to the hopper body 1 is adjustable to adapt to the production of molds with different mold cavity widths.

[0043] In this embodiment, the movable door 2 and the material guide plate 4 are respectively hinged to the side wall of the discharge port 12. The concrete material enters the mold cavity under the guidance of the movable door 2 and the material guide plate 4. By adjusting the deflection angles of the movable door 2 and the material guide plate 4, the lateral distance between the bottom ends of the movable door 2 and the material guide plate 4 is adjusted to jointly adjust the size and discharge angle of the discharge port 12 to be applicable to molds with different widths of mold cavities.

[0044] In order to be able to monitor the weight of the concrete material in the hopper body 1 in real time, at least one weighing sensor (not shown) is connected to the side wall of the hopper body 1. The weighing sensor is electrically connected to the controller 400 and fixed on the second frame body 10b.

[0045] When the controller 400 instructs the frame 100 to move to the X operation section, it instructs the cloth hopper 200 to perform cloth pouring on the Y operation layer of this operation section. Specifically, the controller 400 instructs the second driving member 5 to deflect the material guide plate 4 relative to the hopper body 1 by a preset angle a1 and align the lower end of the material guide plate 4 with this operation section, and instructs the first driving member 3 to deflect the movable door 2 by a preset angle a2 to open the discharge port 12. The concrete material in the hopper body 1 flows out of the discharge port 12 to this operation section under the guidance of the movable door 2 and the material guide plate 4. When the weighing sensor detects that the reduction amount of the concrete material in the hopper body 1 is close to equal to the preset cloth amount of the Y operation layer, and the first distance measuring member 7 detects that the cloth depth of the Y operation layer reaches the preset value, the controller 400 instructs the first driving member 3 to drive the movable door 2 to deflect a certain angle to close the discharge port 12.

[0046] As Figure 3 shown in 5As shown in the figure, in this embodiment, the second driving member 5 can be any one of a cylinder, a hydraulic cylinder, and an electric push rod. One end of the second driving member 5 away from the material guiding plate 4 is hinged to the hopper body 1, and at least one transmission link 51 is connected between the second driving member 5 and the material guiding plate 4. The arrangement of the link makes the adjustment of the deflection angle of the material guiding plate 4 by the second driving member 5 more flexible, which is beneficial to reasonably arrange the position of the second driving member 5 on the hopper body 1. In this embodiment, the number of the transmission links 51 is one. One end of the transmission link 51 is hinged to the second driving member 5, and the other end is hinged to the material guiding plate 4. In other embodiments, there can be two or more transmission links 51, and adjacent transmission links 51 are hinged to each other. Alternatively, on the side of the material guiding plate 4 close to the hopper body 1, a first connecting rod and a second connecting rod forming a predetermined angle are provided. The first connecting rod is hinged to the hopper body 1, and the second connecting rod is hinged to the second driving member 5. The material guiding plate 4 can rotate around the hinge point between the first connecting rod and the hopper body 1. Such an arrangement can also make the rotation of the material guiding plate 4 flexible. Alternatively, the link can be omitted, and the second driving member 5 is directly hinged to the material guiding plate 4. The second driving member 5 can also be a driving structure other than the above that can realize the adjustment of the deflection angle of the material guiding plate 4 relative to the hopper body 1, and no limitation is made here.

[0047] The first driving member 3 can be any one of a cylinder, a hydraulic cylinder, and an electric push rod. One end of the first driving member 3 is hinged to the hopper body 1, and the other end is hinged to the movable door 2. The first driving member 3 controls the opening angle of the movable door 2 to realize the adjustment of the size and the discharge amount of the discharge port 12. In other embodiments, the first driving member 3 can be a driving structure other than the above examples that can realize the adjustment of the deflection angle of the movable door 2 relative to the hopper body 1, and no limitation is made here.

[0048] Further, as Figure 9 and Figure 10 shown, the movable door 2 includes a door main body 21 for opening and closing the discharge port 12 and a connecting seat 22 connected to the door main body 21 at an obtuse angle. The connecting seat 22 is hinged to the first driving member 3. The door main body 21 is provided with a reinforcing member 211 to improve the overall structural strength of the movable door 2. One end of the door main body 21 close to the connecting seat 22 is provided with a mounting hole 211. The door main body 21 is hinged to the hopper body 1 through a pin shaft (not shown) installed in the mounting hole 211. The pin shaft is fixedly connected to the hopper body 1 by welding, screwing, clamping, bonding or other means. The first driving member 3 drives the movable door 2 to rotate around the pin shaft to open and close the discharge port 12.

[0049] Further, as Figure 9 and Figure 10As shown, the movable door 2 is provided with an elastic seal 23 that abuts against the hopper body 1. The gap between the movable door 2 and the hopper body 1 is sealed by the elastic seal 23 to reduce the leakage of concrete. The elastic seal 23 is made of an elastic material such as rubber or sponge. Specifically, for the convenience of installing the elastic seal 23, the elastic seal 23 is an integral body. The cross-sectional dimension of the elastic seal 23 is adapted to the cross-sectional dimension of the door body 21. The elastic seal 23 is snap-fitted with the movable door 2. The elastic seal 23 is provided with a groove, and the movable door 2 is provided with a protrusion 212 that matches the groove. Preferably, the groove is located at the middle position of the elastic seal 23. In other embodiments, the elastic seal 23 is connected to the door body 21 by means of bonding or fasteners. Further, as shown in the figure, one end of the elastic seal 23 close to the connecting seat 22 is in arc contact with the hopper body 1, which is beneficial to ensuring that the movable door 2 and the side wall of the discharge port 12 are always in contact to improve the sealing effect therebetween. Specifically, one end of the elastic seal 23 close to the connecting seat 22 is provided with an arc surface, and the side wall of the discharge port 12 is provided with an abutting member 144 that abuts against the elastic seal 23. The contact portions of the abutting member 144 and the elastic seal 23 are all set to be arcs that are adapted to the arc surface of the elastic seal 23. The abutting member 144 is a column with an arc surface on its side wall. The abutting member 144 is integrally formed with the side wall of the discharge port 12, or the abutting member 144 is fixedly connected to the side wall of the discharge port 12 by means of welding or bonding. Preferably, in order to make the connection between the elastic seal 23 and the door body 21 closer, one end of the door body 21 close to the connecting seat 22 is provided with an arc surface that is adapted to the arc surface of the elastic seal 23.

[0050] As Figure 3 , 5 , 9 shown, the bottom of the hopper body 1 is provided with a relatively arranged first baffle 141 and a second baffle 142, and two side baffles 143 located on both sides of the first baffle 141 and the second baffle 142. The first baffle 141, one of the side baffles 143, the second baffle 142, and the other side baffle 143 are sequentially spliced to enclose the side wall of the discharge port 12. The bottom end of the first baffle 141 is located above the bottom end of the second baffle 142. The hinge point of the movable door 2 and the side wall of the discharge port 12 is located above the hinge point of the guide plate 4 and the side wall of the discharge port 12. Specifically, the movable door 2 and the guide plate 4 are respectively hinged to the side baffle 143 on both sides of the discharge port 12. The hinge point of the guide plate 4 and the side baffle 143 is located at a position close to the bottom of the second baffle 142, and the hinge point of the movable door 2 and the side baffle 143 is located at a position close to the bottom of the first baffle 141. Such a setting realizes that on the basis of improving the cloth feeding accuracy and cloth feeding efficiency, the bottom structure of the cloth feeding hopper 200 is more compact, does not change the size of the discharge port 12 at the bottom of the cloth feeding hopper 200 and the volume of the cloth feeding hopper 200, and saves costs.

[0051] Further, as Figure 5-7As shown, two or more discharge openings 12 are provided at intervals along the length direction of the mold at the bottom of the hopper body 1. Arranging two discharge openings 12 to distribute materials to the same working section simultaneously can improve the material distribution efficiency. Guide plates 4 are correspondingly provided at the bottom on the same side of the multiple discharge openings 12. At the bottom of the side wall of the discharge opening 12, a rotating shaft 13 extending along its length direction is provided. The rotating shaft 13 is hinged to the side wall of the discharge opening 12. The multiple guide plates 4 are installed on the rotating shaft 13, and the rotating shaft 13 is hinged to the second driving member 5 or the transmission connecting rod 51. Preferably, in combination with Figure 6 As shown, the length L2 of the rotating shaft 13 is greater than the total length L1 of the bottom of the hopper body 1. There are two second driving members 5, and the output ends of the two second driving members 5 are respectively hinged to both ends of the rotating shaft 13. The second driving member 5 drives the rotating shaft 13 to rotate, thereby driving the multiple guide plates 4 to rotate to adjust the angles of the multiple guide plates 4, and the control is simple. In other embodiments, the guide plate 4 at each discharge opening 12 is independently driven by a driving member.

[0052] Furthermore, as Figure 5 , 7 , 8 shown, two or more discharge openings 12 arranged side by side are provided along the width direction of the mold cavity of the hopper body 1. One discharge opening 12 corresponds to one precast pile mold for material distribution, so that the material distribution hopper 200 can distribute materials and pour for two or more precast pile molds, improving the material distribution efficiency. A guide plate 4 is correspondingly provided at the bottom of each discharge opening 12. In the width direction of the mold cavity, the two guide plates 4 corresponding to two adjacent discharge openings 12 are arranged adjacent to each other. On the basis of improving the material distribution accuracy and efficiency, the bottom structure of the material distribution hopper 200 is made more compact.

[0053] Furthermore, when it is necessary to move horizontally a certain distance to adjust the positions of the material distribution hopper 200 and the vibrator 300 so as to accurately reach the position of the preset working section, as Figure 2As shown in the figure, the rack 100 includes a first frame body 10a spanning more than two molds, and a second frame body 10b mounted on the first frame body 10a and capable of moving laterally along the first frame body 10a. The cloth hopper 200 and the vibrator 300 are arranged on the second frame body 10b. The first frame body 10a is provided with a first moving mechanism 101 that moves along the length direction of the mold, and the second frame body 10b is provided with a second moving mechanism 102 that moves laterally. The first moving mechanism 101 and the second moving mechanism 102 are respectively electrically connected to the controller 400, and a longitudinal displacement sensor 103 is arranged on the first frame body 10a. The cloth vibrating integrated machine is moved a predetermined distance along the length direction of the precast pile mold through the first moving mechanism 101, and the second frame body 10b, the cloth hopper 200 and the vibrator 300 are moved laterally along the first frame body 10a to the working section of the precast pile mold to be cloth-poured. Among them, the first moving mechanism 101 and the second moving mechanism 102 include a walking part and a driving device for driving the walking part to move. The walking part is a pulley, and of course it can also be a roller or other moving structures. The driving device can be a braking motor, and the walking speed can be coordinated with the cloth-pouring and vibrating operations on site. On the sides of the two molds located on the outermost side in the mold arrangement and away from each other, there are respectively tracks arranged along the length direction of the mold for the walking part of the first moving mechanism 101 to move, and the walking part of the second moving mechanism 102 can move along the first frame body 10a.

[0054] When the cloth vibrating integrated machine finishes layered cloth-pouring and layered vibrating of the previous precast pile mold, the cloth hopper 200 and the vibrator 300 can move laterally along the second frame body 10b to the next precast pile mold to be cloth-poured. Then, the cloth vibrating integrated machine moves back and forth along the length direction of the precast pile mold to perform layered cloth-pouring and layered vibrating on the precast pile mold. In other embodiments, the rack 100 only includes the first frame body 10a, the cloth hopper 200 and the vibrator 300 are installed on the first frame body 10a, and the cloth hopper 200 and the vibrator 300 can only move along the length of the precast pile mold. The total cloth-pouring width of the cloth hopper 200 is greater than or equal to the cavity widths of more than two precast pile molds. There are more than two discharge ports 12 arranged along the width direction of the mold at the bottom of the cloth hopper 200. The total vibrating width of the vibrator 300 is greater than or equal to the cavity widths of more than two precast pile molds. The vibrator 300 includes more than two rows of vibrating members 310 arranged along the width direction of the mold, so that the cloth vibrating integrated machine can perform layered cloth-pouring and vibrating on more than two precast pile molds arranged side by side at the same time.

[0055] As Figure 11 、 12As shown, the vibrator 300 includes a support frame 301 provided on the frame 100, a vibrating member 310 provided on the support frame 301, and a lifting drive member for driving the vibrating member 310 to lift and lower relative to the support frame 301. In this embodiment, in order to make the lifting and lowering of the vibrating member 310 more stable, there are two lifting drive members and they are located on both sides of the support frame 301. The lifting drive member includes a driving sprocket 321 and a driven sprocket 322 mounted on the support frame 301, a vertical chain 323 wound around the driving sprocket 321 and the driven sprocket 322, and a rotary drive 324 for driving the driving sprocket 321 to rotate. The rotary drive 324 can be a motor, and the vibrating member 310 is connected to the vertical chain 323. The chain mechanism can provide a greater lifting force to adapt to the insertion or extraction of the vibrating member 310 into or out of the mold cavity. In other embodiments, the lifting drive member can be a hydraulic cylinder, a pneumatic cylinder, an electric push rod, a winch, etc. There is also a lifting guide member provided between the support frame 301 and the vibrating member 310 to guide the lifting and lowering of the vibrating member 310 to ensure that the vibrating member 310 moves vertically. The lifting guide member includes a vertical slide rail 332 provided on one of the support frame and the lifting bracket 311, and a slider 331 provided on the other of the support frame and the lifting bracket 311. The slider 331 is slidably engaged with the vertical slide rail 332, and the slider 331 has an I-shaped groove, a trapezoidal groove, an arc-shaped groove, a dovetail groove, etc. that cooperate with the vertical slide rail 332.

[0056] As Figure 11 , 12As shown, the vibrator 310 includes a lifting bracket 311 connected to a vertical chain 323, a guide 312 mounted on the lifting bracket 311 and extending horizontally, at least one support plate 313 slidingly engaged with the guide 312 and extending longitudinally, and a plurality of vibrating units 314 arranged longitudinally and spaced apart on the support plate 313. The vibrating units 314 are arranged in at least one row in the horizontal direction. The lifting bracket 311 is provided with a connecting plate 3111 connected to the vertical chain 323. The connecting plate 3111 is detachably fixed to the vertical chain link via welding or screwing. The vibrating unit 314 includes a vibrating motor 3141 mounted on the support plate 313 and a vibrating rod 3142 suspended from the vibrating motor 3141. The vibrating rod 3142 is connected to the output shaft of the vibrating motor 3141. The vibrating rod 3142 tamps the concrete, compacting it and ensuring the quality of the precast piles. The lifting bracket 311 is also equipped with a transverse adjustment mechanism that drives the support plate 313 along the guide member 312. The first transverse adjustment mechanism 315 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, or any other structure other than those mentioned above, as long as it can enable the support plate 313 to move laterally a certain distance to adjust the positions of the multiple vibrating units 314 to meet different vibration requirements. The guide members 312 are two guide rods, and each end of the support plate 313 is equipped with a sliding sleeve that fits over and slides along the corresponding guide rods. In this embodiment, there are two support plates 313, each equipped with a row of vibrating units 314, with each precast pile mold corresponding to a row of vibrating units 314. In other embodiments, the number of support plates 313 is not limited to two, and can be one or more than three, and the support plates 313 can be equipped with more than two rows of vibrating units 314. In actual production, the specific number of rows of vibrating units 314 corresponding to a precast pile mold is determined according to the mold cavity width of the precast pile mold and the vibration width of the vibrating unit 314 , that is, a precast pile mold can correspond to more than two rows of vibrating units 314 .

[0057] The rotary driver 324 and the vibrating motor 3141 are electrically connected to the controller 400. When vibrating the Y+1 working layer, the controller 400 instructs the rotary driver 324 to drive the vertical chain 323 to rotate, thereby driving the vibrating member 310 to descend. When the second distance measuring member 316 detects that the lower end of the vibrating member 310 (i.e., the lower end of the vibrating rod 3142) is inserted into the Y working layer 0.1h Y+1 to 0.25h Y+1 The information of the depth position is transmitted to the controller 400, and the controller 400 instructs the rotary driver 324 to stop and instructs the vibrating motor 3141 to drive the vibrating rod 3142 to perform the vibrating operation. After vibrating for a preset time, the controller 400 instructs the vibrating motor 3141 to stop and instructs the rotary driver 324 to drive the vertical chain 323 to rotate in the opposite direction, thereby driving the vibrating member 310 to rise, so that the vibrating rod 3142 is separated from the mold cavity.

[0058] To improve the accuracy of the lateral movement of the vibrating unit 314, a guiding member 312 extending laterally is provided at the bottom of the support frame 301, a positioning plate 302 corresponding to the support plate 313 and movable along the guiding member 312, and a second lateral movement adjusting mechanism 303 for driving the positioning plate 302 to move along the guiding member 312. The positioning plate 302 extends longitudinally, and the lower parts of the vibrating rods 3142 of at least one row of vibrating units 314 penetrate through the positioning plate 302. The structure of the second lateral movement adjusting mechanism 303 is the same as that of the first lateral movement adjusting mechanism 315 and is electrically connected to the controller 400 respectively. There are two guiding members 312 and they are guide rods, and sliding sleeves sleeved on the corresponding guiding members 312 are provided at both ends of the positioning plate 302. When it is necessary to adjust the lateral position of the vibrating unit 314 on the support plate 313, the controller 400 instructs the first lateral movement adjusting mechanism 315 and the second lateral movement adjusting mechanism 303 to act simultaneously, so that the support plate 313 and the positioning plate 302 move the same distance laterally to move the vibrating unit 314 to a preset position.

[0059] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
