Description

Technical Field

[0001] The present invention mainly relates to the field of pipe pile production and manufacturing, and in particular to an automated bolt fastening and disassembly system for a pipe pile mould. Background Art

[0002] Pipe piles are widely used in current construction projects. Pipe pile molds are used during their production. These molds consist of an upper mold cover and a lower mold cover, which are secured together with multiple studs. These molds can be reused multiple times.

[0003] Therefore, during the production of pipe piles, the pipe pile molds must be used for multiple and different operations: for example, tightening the bolts of the pipe pile molds to facilitate the subsequent centrifugation of concrete after mold closing; transporting the centrifugally formed centrifugal square piles with molds for maintenance; removing the bolts of the pipe pile molds before demoulding to facilitate demoulding and transportation of finished pipe piles; and cleaning the pipe pile molds afterwards. The following technical problems arise during the tightening and disassembling of bolts on the pipe pile molds:

[0004] 1. Currently, many operations are done manually, but the pipe pile mold is very long (more than ten meters or even dozens of meters) and has a large number of bolts, which not only leads to low work efficiency, high labor costs, high production risks, but also a low level of automation.

[0005] Second, the current work efficiency is low. Many companies have to wait until the pipe pile mold stops being transported before tightening or disassembling the bolts and then transporting the pipe pile mold, which greatly reduces work efficiency.

[0006] 3. Currently, some people use devices such as pneumatic jackhammers to tighten and disassemble bolts. First, pneumatic jackhammers make a huge noise, causing noise pollution and being detrimental to production operations. Second, the torque is insufficient, resulting in the bolts not being tightened, affecting the subsequent centrifugal operation of mold closing. In addition, since the bolts will expand after installation, insufficient torque will also result in the bolts not being loosened, which in turn affects the subsequent demolding operation. Moreover, since the bolts are too tight to be twisted but the rotary drill does not stop twisting in time, a "machine jump" phenomenon occurs, resulting in either damage to the rotary drill or damage to the bolt head. Fourth, after the bolts are loosened, they may get stuck in the rotary drill. If the bolts are not removed in time, it will inevitably affect the next operation. Manual removal increases labor costs, reduces work efficiency, and may cause production safety accidents.

[0007] 5. The current automation level is low. In order to improve the automation level, a batch of automated equipment needs to be produced to complete the above-mentioned different operations. However, in the automated operation, it is necessary to first position the pipe pile mold in transit. Only by ensuring accurate positioning can other tooling (such as bolt tightening devices, bolt disassembly devices, etc.) perform subsequent accurate automated operations on the pipe pile mold in transit; and during this positioning process, it is necessary to ensure that the pipe pile mold cannot stop being transported, and then the work efficiency can be greatly improved, the labor cost can be greatly reduced, and the production risk can be greatly reduced. In addition, due to the long length and heavy weight of the pipe pile mold, there will inevitably be horizontal deviations during transportation, so it is inconvenient to move the pipe pile mold by positioning and adjusting the posture. The positioning equipment can only adapt to the pipe pile mold, while positioning, moving the positioning mechanism itself back and forth and left and right. Therefore, it is very necessary to invent a device that can automatically position the pipe pile mold in transit.

[0008] 5. Currently, many devices have poor integration, occupy a large area, and have high requirements for factory usage area. Summary of the Invention

Each of the horizontal positioning clamping frames is also provided with one or more obliquely arranged second connecting rods, and the lower end of the second connecting rod is hinged to the sliding sleeve, and the higher end is hinged to the frame.

[0019] As a further improvement of the present invention, the positioning guide sleeve includes a positioning groove for clamping and positioning the running wheel, and the groove portion of the positioning groove is provided with two guide plates arranged obliquely, which are used to form a trumpet-shaped guide groove to guide the running wheel into the positioning groove when clamping; a vertical mounting plate is fixed in the positioning groove, and a guide sleeve is provided on the mounting plate, and a movable guide rod is horizontally passed through the guide sleeve, and a vertical positioning clamping plate is provided on one end of the guide rod close to the groove of the positioning groove, and a limit plate is provided on the other end of the guide rod, and the horizontal sensing component is provided at the tail end of the positioning groove.

[0026] Compared with the prior art, the advantages of the present invention are:

[0027] First, the automated bolt fastening and disassembly system for the pipe pile mold of the present invention has precise positioning and is equipped with a special vertical positioning device 3 and a horizontal positioning device 4. It can automatically position the pipe pile mold 9 in the vertical direction and horizontally position it in the left and right directions during transmission, thereby providing an excellent positioning signal with high positioning accuracy, facilitating the automated operation of multiple fastening and disassembly devices 5, greatly improving work efficiency and greatly reducing labor costs.

[0028] Secondly, the automated bolt fastening and disassembly system for the pipe pile mold of the present invention has a compact structure and high integration. The mobile positioning frame 2, the vertical positioning device 3, the horizontal positioning device 4 and multiple fastening and disassembly devices 5 are all integrated and installed in the cabinet 1, cooperating and supporting each other, and occupying a small area.

[0029] Third, the automated bolt fastening and disassembly system for the pipe pile mold of the present invention has a high level of automation, which can enable the pipe pile mold 9 to complete positioning operations and bolt fastening and disassembly operations without stopping transmission, greatly shortening the construction operation time and greatly improving work efficiency.

[0030] Fourth, the present invention is an automated bolt fastening and disassembly system for pipe pile molds. The vertical positioning device can flexibly use running wheels to automatically position the pipe pile molds by setting up matching telescopic mechanisms, positioning rods, positioning hooks and sensing components, thereby providing excellent positioning signals, facilitating automated operations of automated operating equipment, greatly improving work efficiency and greatly reducing labor costs.

[0031] Fifth, the automated bolt tightening and disassembly system for pipe pile molds of the present invention features a horizontal retention mechanism in the vertical positioning device to further ensure the horizontality of the positioning rod. When the telescopic mechanism drives the positioning rod downward, a spring presses the second slider outward, thereby simultaneously maintaining the two connecting rods in a tightened outward position. Ultimately, the two connecting rods maintain an excellent horizontal position for improved positioning accuracy.

[0032] Sixth, the present invention provides an automated bolt fastening and disassembly system for pipe pile molds. The horizontal positioning device can be flexibly installed on the left and right working surfaces of the pipe pile mold, and the running wheel can be used to automatically position the pipe pile mold, facilitating automated operation of automated operating equipment, greatly improving work efficiency and greatly reducing labor costs.

[0033] Seventh, the automated bolt fastening and disassembly system for the pipe pile mold of the present invention has a horizontal positioning device provided with a special structure of a slide rod, a slide sleeve and an inclined connecting rod. This structure can effectively counteract the upward reaction force generated by the running wheel on the horizontal positioning clamping frame, thereby greatly extending the service life of the equipment and ensuring the implementation of high-precision positioning.

[0034] Eighth, the automated bolt tightening and disassembly system for pipe pile molds of the present invention further includes two guide plates for forming a trumpet-shaped guide slot. As the positioning guide sleeve approaches the running wheel, it gradually guides the running wheel until it is finally positioned and clamped into the positioning slot. During this guiding motion, the frame undergoes translational sliding in the directions of arrows AB in the figure. Ultimately, the running wheel is clamped and positioned in the positioning slot, achieving extremely precise positioning. This not only solves the positioning problem in the directions of arrows CD, but also addresses the positioning problem in the directions of arrows AB, resulting in extremely high positioning accuracy.

[0035] Ninth, the present invention provides an automated bolt fastening and disassembly system for pipe pile molds. The fastening and disassembly device has a high level of automation and can perform both bolt fastening and disassembly operations through forward and reverse rotation, thereby greatly improving work efficiency and reducing labor costs and production risks.

[0036] Tenth, the present invention is an automated bolt fastening and disassembly system for pipe pile molds. The fastening and disassembly device is designed to cooperate with and complement each other through the rotation drive mechanism, lifting drive mechanism, transmission spline rod, transmission spline sleeve, impact hammer, elastic member, bearing assembly, sleeve assembly and other components. The sleeve assembly actively "finds" the bolt head by rotating and descending, and finally firmly "sleeves" on the bolt, so that the sleeve assembly can transmit excellent rotational torque to the bolt. This allows the rotation drive mechanism to operate without the use of a high-power, high-noise drive device like a jackhammer, greatly reducing noise pollution. At the same time, the excellent tightening and loosening effect is very convenient for the subsequent mold closing centrifugal operation and demolding operation to proceed normally.

[0037] Eleventh is the automated bolt fastening and disassembly system for the pipe pile mold of the present invention. Since the sleeve assembly of the fastening and disassembly device is firmly "pressed" on the bolt, a downward pressure is always applied to the bolt head while the knob is turned, so there will be no "machine jump" phenomenon, no damage to the sleeve assembly or bolt, and the service life of the equipment is extended.

[0038] Twelve is the automated bolt fastening and disassembly system for the pipe pile mold of the present invention. The transmission spline sleeve of the fastening and disassembly device is also fixed with an impact baffle above the impact hammer. The impact baffle is used to produce collision cooperation with the automatically retracted impact hammer, thereby effectively solving the problem of the bolt being stuck in the sleeve assembly. It not only facilitates the sleeve assembly to quickly carry out the next batch of operations, but also automatically disengages without manual intervention, greatly reducing labor costs, improving work efficiency, and eliminating possible safety hazards in production.

[0062] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0063] like Figures 1 to 21 As shown, the present invention provides an automated bolt fastening and disassembly system for pipe pile molds, including a cabinet 1, the cabinet 1 is provided with a channel for transmitting the pipe pile mold 9, and is also provided with a start sensor (as shown by M in the figure). A movable positioning frame 2 that can move along the transmission direction is provided above the channel on the cabinet 1, and the positioning frame 2 is provided with a vertical positioning device 3, a horizontal positioning device 4 and a plurality of fastening and disassembly devices 5. The vertical positioning device 3 is used to drop from above to vertically position the pipe pile mold 9 below, and then send a vertical positioning signal, and enable the mobile positioning frame 2 to be transmitted synchronously with the pipe pile mold 9; the horizontal positioning device 4 includes two vertical horizontal positioning clamping frames 42 arranged opposite to each other on the left and right, and is used to clamp the pipe pile mold 9 according to the vertical positioning signal to form a horizontal positioning, and then send a horizontal positioning signal, so that the plurality of fastening and disassembly devices 5 can perform fastening and disassembly operations on the plurality of bolts on the pipe pile mold 9. In this embodiment, slide rail assemblies are provided on both sides of the mobile positioning frame 2, allowing the mobile positioning frame 2 to translate along the conveying direction of the pipe pile mold 9 on the cabinet 1. At the same time, a translation cylinder (as shown by K in the figure) is also provided on one side of the mobile positioning frame 2 to actively drive the translation of the mobile positioning frame 2. The specific implementation principle is as follows:

[0064] When the pipe pile mold 9 is transported into the cabinet 1 by a flat car, the start sensor senses this and activates the vertical positioning device 3, causing it to drop from above to vertically position the transported pipe pile mold 9 below and emit a vertical positioning signal. Simultaneously, since the mobile positioning frame 2 can translate on the cabinet 1, the transported pipe pile mold 9 inevitably drives the mobile positioning frame 2 forward through the connected vertical positioning device 3, thereby driving the horizontal positioning device 4 and the multiple fastening and disassembly devices 5 on the mobile positioning frame 2 to translate together. During this process, the horizontal positioning device 4, upon receiving the vertical positioning signal, activates. Its two vertically opposed horizontal positioning clamping frames 42 begin to clamp the pipe pile mold 9 in response to the vertical positioning signal, gradually clamping it into a horizontal position and emitting a horizontal positioning signal. At this point, the transported pipe pile mold 9 is vertically positioned by the vertical positioning device 3 above and horizontally positioned by the horizontal positioning clamping frames 42 on both sides. At this time, the multiple fastening and disassembling devices 5 that have received the horizontal positioning signal start to operate, and perform precise fastening or disassembly operations on the multiple bolts on the pipe pile mold 9 below.

[0065] When the bolt tightening or disassembly operation is complete, the fastening and disassembly device 5 rises and returns to its original position. The two vertical horizontal positioning clamping frames 42 translate left and right back to their original positions, no longer clamping the pile mold 9. The vertical positioning device 3 rises and returns to its original position. At this point, the translation cylinder rapidly drives the mobile positioning frame 2 to translate back to its original position. The vertical positioning device 3 then descends from above again to vertically position the pile mold 9 in transit below and issues a vertical positioning signal. The horizontal positioning device 4 once again achieves horizontal positioning and issues a horizontal positioning signal. The multiple fastening and disassembly devices 5 begin operating again, and the cycle continues.

[0066] Through the above special scientific design, it has the following technical advantages:

[0067] First, the automated bolt fastening and disassembly system for the pipe pile mold of the present invention has precise positioning and is equipped with a special vertical positioning device 3 and a horizontal positioning device 4. It can automatically position the pipe pile mold 9 in the vertical direction and horizontally position it in the left and right directions during transmission, thereby providing an excellent positioning signal with high positioning accuracy, facilitating the automated operation of multiple fastening and disassembly devices 5, greatly improving work efficiency and greatly reducing labor costs.

[0068] Secondly, the automated bolt fastening and disassembly system for the pipe pile mold of the present invention has a compact structure and high integration. The mobile positioning frame 2, the vertical positioning device 3, the horizontal positioning device 4 and multiple fastening and disassembly devices 5 are all integrated and installed in the cabinet 1, cooperating and supporting each other, and occupying a small area.

[0069] Third, the automated bolt fastening and disassembly system for the pipe pile mold of the present invention has a high level of automation, which can enable the pipe pile mold 9 to complete positioning operations and bolt fastening and disassembly operations without stopping transmission, greatly shortening the construction operation time and greatly improving work efficiency.

[0070] like Figures 4 to 10 As shown, further, in a preferred embodiment, the vertical positioning device 3 includes a telescopic mechanism 31 and a positioning rod 32. The positioning rod 32 is connected to the driving end of the telescopic mechanism 31. The positioning rod 32 is provided with a positioning hook 33 protruding toward the pipe pile mold 9. The positioning hook 33 is slidably arranged on the positioning rod 32 along the conveying direction of the pipe pile mold 9. The positioning rod 32 is also provided with a vertical sensing component 34 near the positioning hook 33, which is configured to generate a sensing signal when the positioning hook 33 slides. During vertical positioning operation, the telescopic mechanism 31 extends and drives the positioning rod 32 toward the conveying pipe pile mold 9, so that the positioning hook 33 hooks the running wheel 91 on the pipe pile mold 9 and is then driven by the pipe pile mold 9 to slide, causing the vertical sensing component 34 to generate a sensing signal. The specific implementation principle is as follows:

[0071] Since the pipe pile mold 9 is very long and is equipped with multiple running wheels 91 arranged at equal intervals (existing structure), each running wheel 91 can serve as a positioning reference point. During operation, the telescopic mechanism 31 drives the positioning rod 32 downward. At this time, the pipe pile mold 9 is transported to the bottom of the positioning rod 32, and the first protruding running wheel 91 on the pipe pile mold 9 contacts the positioning hook 33 and drives the positioning hook 33 to slide forward. Once the positioning hook 33 slides, the vertical sensing component 34 sends a sensing signal. Once the operation is completed, the telescopic mechanism 31 drives the positioning rod 32 upward to separate it from the first running wheel 91. During the next operation, the telescopic mechanism 31 drives the positioning rod 32 down again. Since the pipe pile mold 9 continues to be transported, the second transported running wheel 91 continues to hook the positioning hook 33 and slide forward. Then the vertical sensing component 34 sends a sensing signal again, and the second operation is carried out. This cycle continues. The above special scientific design has the following technical advantages:

[0072] The automated bolt fastening and disassembly system for the pipe pile mold of the present invention, by providing a coordinated telescopic mechanism 31, a positioning rod 32, a positioning hook 33 and a vertical sensing component 34, can flexibly utilize the running wheel 91 to automatically position the pipe pile mold 9, thereby providing an excellent vertical positioning signal. Moreover, the pipe pile mold 9 can maintain a transmission state during the operation, which facilitates automated operation of automated operation equipment, greatly improves work efficiency and greatly reduces labor costs.

[0073] Furthermore, in a preferred embodiment, the positioning rod 32 is hollow and has a slot (in this embodiment, as shown in the figure, the slot is provided on the bottom surface of the positioning rod 32). The positioning hook 33 includes a movable portion 331 and a convex hook portion 332 connected to each other. The movable portion 331 is slidably disposed within the positioning rod 32, with the convex hook portion 332 protruding outward through the slot. A first elastic member 321 is provided at the front end of the movable portion 331 within the positioning rod 32, contacting the movable portion 331. The first elastic member 321 is used to cushion the positioning hook 33 when it is driven forward by the pile mold 9 and to allow the positioning hook 33 to slide backward to reset under elastic recovery after the operation is completed. The hollow structure of the positioning rod 32 facilitates the linear movement of the movable portion 331 within the rod, and the overall structure is simple and compact, making it easy to install and manufacture. The first elastic member 321 has two special functions: First, when the positioning hook 33 is driven forward by the pile mold 9, the front end of the movable portion 331 gradually compresses the first elastic member 321, cushioning the movable portion 331, i.e., the positioning hook 33. This prevents the movable portion 331 from striking the end of the positioning rod 32, facilitating rapid automated operation of the horizontal positioning device 4 and the multiple fastening and disassembly devices 5. Second, once the operation is completed, the telescopic mechanism 31 drives the positioning rod 32 upward, disengaging it from the first running wheel 91. After disengagement, the movable portion 331, under the elastic recovery action of the first elastic member 321, slides backward to return to the vertical sensing assembly 34, facilitating the next positioning sensing operation. Of course, in other embodiments, the first elastic member 321 may not be located at the front end of the movable portion 331; it may be located at the rear end of the movable portion 331 to hold the movable portion 331 as it slides forward and pull it back to its original position after the operation is completed. Such simple position changes are also within the scope of protection of the present invention.

[0074] Furthermore, in a preferred embodiment, vertical sensing assembly 34 includes a vertical sensor 341 and a vertical sensing plate 342 disposed within positioning rod 32. Vertical sensing plate 342 is fixed to the rear end of movable portion 331. Vertical sensor 341 is disposed behind sensing plate 342 and is configured to generate a sensing signal when vertical sensing plate 342 separates from vertical sensor 341. Of course, in other embodiments, other configurations, such as position sensors, are possible, and such simple position changes are within the scope of the present invention.

[0075] Furthermore, in a preferred embodiment, the movable portion 331 is provided with one or more limiting waist-shaped holes 3311 along the sliding direction, and a first limiting rod 322 is fixed to each limiting waist-shaped hole 3311 on the positioning rod 32, extending into the limiting waist-shaped hole 3311, for limiting the sliding movement of the movable portion 331. The cooperation between the limiting waist-shaped holes 3311 and the first limiting rod 322 limits the forward and backward movement of the movable portion 331, which has two special functions: first, it limits the travel so that the movable portion 331 does not violently collide with the front and back, thereby preventing the first elastic member 321 in front from being damaged, and also preventing the vertical sensor 341 in the rear from being damaged during reset. Second, it can limit the sliding movement of the movable portion 31, making the movement precise and facilitating the realization of precise positioning.

[0076] Furthermore, in a preferred embodiment, the positioning rod 32 is provided with two or more positioning hooks 33 along the axial direction, which are used to simultaneously hook onto two or more running wheels 91 on the pile mold 9 during positioning operations. Each positioning hook 33 is equipped with a vertical sensing component 34. Because the pile mold 9 is very long and has multiple running wheels 91 spaced evenly apart, the area between each two running wheels 91 can serve as a positioning operation point. By providing two or more positioning hooks 33 to simultaneously hook onto two or more running wheels 91 on the pile mold 9, the multiple vertical sensing components 34 corresponding to the two or more positioning hooks 33 only operate when they all emit signals, further improving positioning accuracy and avoiding operational errors. Furthermore, an operation point can be formed precisely between two adjacent running wheels 91, allowing for automated operations to be carried out section by section, resulting in better results and higher efficiency.

[0077] Furthermore, in a preferred embodiment, the positioning rod 32 is simultaneously connected to two or more telescopic mechanisms 31. These two or more telescopic mechanisms 31 are arranged sequentially along the axial direction of the positioning rod 32 and are used to simultaneously drive the positioning rod 32 to ensure smooth movement of the positioning rod 32. In this embodiment, two telescopic mechanisms 31 are provided. Because two or more positioning hooks 33 are axially provided on the positioning rod 32, the positioning rod 32 has a certain length. To ensure the horizontal raising and lowering of the positioning rod 32, and thereby ensure that each positioning hook 33 can synchronously hook onto the running wheel 91, and to ensure that the positioning rod 32 does not shake when the pile mold 9 drives the positioning hook 33 to move, the two telescopic mechanisms 31 are provided to move synchronously. This not only structurally ensures the horizontal and stable position of the positioning rod 32, but also ensures the horizontal raising and lowering of the positioning rod 32 through the driving action.

[0078] Furthermore, in a preferred embodiment, the telescopic mechanism 31 includes a mounting frame 311, a telescopic drive assembly 312, and two telescopic limit rods 313. The mounting frame 311 is fixed to the mobile positioning frame 2. The telescopic drive assembly 312 is fixed to the mounting frame 311, connecting the telescopic drive end to the positioning rod 32. The two telescopic limit rods 313 are arranged parallel to either side of the telescopic drive assembly 312. One end of each telescopic limit rod 313 is fixedly connected to the positioning rod 32, and the other end of each telescopic limit rod 313 is movably mounted on a vertical bearing seat on the mounting frame 311 to limit the movement of the positioning rod 32. The mounting frame 311 can be directly fixed to the mobile positioning frame 2 via a fixing assembly. The telescopic drive assembly 312 then drives the telescopic mechanism 313. Furthermore, to ensure that the positioning rod 32 can be raised and lowered horizontally and that the positioning hook 33 does not cause the positioning rod 32 to shake when moving, two telescopic limit rods 313 are further provided. The two telescopic limiting rods 313 can further ensure the horizontal lifting and lowering of the positioning rod 32 , and can also further ensure the stability of the positioning rod 32 .

[0079] Furthermore, in a preferred embodiment, it also includes a horizontal maintaining mechanism 35 for maintaining the horizontal state of the positioning rod 32 during movement. The horizontal maintaining mechanism 35 includes a first slide bar 351, a first slider 352, two connecting rods 353, two second slide bars 354, two second slide bars 355 and two springs 356. The first slide bar 351 is arranged along the extension direction of the telescopic mechanism 31, and the first slider 352 is slidably arranged on the first slide bar 351; the two second slide bars 354 are fixed to the positioning rod 32 along the axial direction of the positioning rod 32, and are respectively arranged on the left and right sides of the first slide bar 351, and each second slide bar 354 is provided with a second slide bar 355; the lower ends of the two connecting rods 353 are respectively hinged to a second slider 355, and the upper ends are both hinged to the first slider 352; each second slide bar 354 is sleeved with a spring 356, which is used to make the second slider 355 gradually squeeze the spring 356 during the extension driving process of the telescopic mechanism 31. Because the positioning rod 32 is provided with two or more positioning hooks 33 along the axial direction, the positioning rod 32 has a certain length. To further ensure the horizontality of the positioning rod 32, a horizontal maintenance mechanism 35 is provided. When the telescopic mechanism 31 drives the positioning rod 32 to gradually descend, the first slider 352 first descends along the first slide bar 351 under the pulling action of the connecting rod 353. When the first slider 352 descends into place, the positioning rod 32 continues to descend, causing the lower ends of the two connecting rods 353 to gradually move closer, and at this time, the two second sliders 355 also gradually move closer. During this process, the two second sliders 355 gradually press the spring 356 inward, that is, the spring 356 presses the second slider 355 outward, thereby causing the two connecting rods 353 to synchronously maintain an outwardly braced state. Ultimately, the positioning rod 32 is maintained in an excellent horizontal state through the two connecting rods 353, improving the accuracy of positioning.

[0080] like Figures 11 to 17 As shown, in a preferred embodiment, the horizontal positioning device 4 includes a frame 41, which is further equipped with a drive assembly 45 connected to two horizontal positioning clamping frames 42. Each horizontal positioning clamping frame 42 has a positioning guide sleeve 43 at its bottom, and a horizontal sensing assembly 44 is installed within the positioning guide sleeve 43. During operation, the drive assembly 45 drives the two horizontal positioning clamping frames 42 to gradually approach each other, guiding and clamping the running wheel 91 on the pile mold 9 into the left and right positioning guide sleeves 43 to achieve positioning, so that the horizontal sensing assembly 44 emits a sensing signal. The specific implementation principle is as follows:

[0081] Because the pile mold 9 is very long and has multiple equally spaced running wheels 91, each running wheel 91 can serve as a positioning reference point. During operation, as shown in the figure, when the horizontal positioning device 4 receives a vertical positioning signal, the drive assembly 45 drives the two horizontal positioning clamping frames 42 to gradually approach each other, ultimately allowing the left and right positioning guide sleeves 43 to guide and clamp the running wheels 91 on the pile mold 9 into the left and right positioning guide sleeves 43 to achieve positioning. After the operation is completed, the drive assembly 45 drives the two horizontal positioning clamping frames 42 to gradually separate, so that the left and right positioning guide sleeves 43 no longer clamp the running wheels 91 in position, and the cycle continues. During the positioning process, it is assumed that the pile mold 9 is not exactly at the center between the two horizontal positioning clamping frames 42, and it is assumed that the pile mold 9 is closer to the right horizontal positioning clamping frame 42. At this time, when the driving component 45 drives the two horizontal positioning clamping frames 42 to gradually approach each other, and the positioning guide sleeve 43 on the right horizontal positioning clamping frame 42 has clamped the right end of the running wheel 91 into position, the left horizontal positioning clamping frame 42 will continue to move until the left end of the running wheel 91 is also clamped, thereby forming a horizontal centering positioning, which solves the position positioning problem in the direction of the arrow CD in the figure.

[0082] Through the above special scientific design, the following technical advantages are achieved: the present invention can be flexibly installed on the left and right working surfaces of the pipe pile mold 9 by setting a matching drive component 45, a horizontal positioning clamping frame 42 and a positioning guide sleeve 43, and then the pipe pile mold 9 is automatically positioned by using the running wheel 91, which facilitates the automated operation of the automated operation equipment, greatly improves work efficiency and greatly reduces labor costs.

[0083] Furthermore, in a preferred embodiment, a horizontal slide rail assembly is disposed on the frame 41, and the tops of the two horizontal positioning and clamping frames 42 are slidably and translationally mounted on the frame 41 via the slide rail assembly. Each horizontal positioning and clamping frame 42 is vertically disposed with a third slide bar 421, which is sleeved with a slide sleeve 422. Each horizontal positioning and clamping frame 42 is also provided with one or more obliquely arranged second connecting rods 423, with the lower end of the second connecting rod 423 hinged to the slide sleeve 422 and the upper end hinged to the frame 41. In this embodiment, each horizontal positioning and clamping frame 42 is provided with two obliquely arranged second connecting rods 423. Through repeated tests and demonstrations, it has been found that during the clamping process, in order to ensure accurate positioning, the drive assembly 45 will provide extremely strong clamping force to the two horizontal positioning clamping frames 42, so the running wheel 91 will inevitably generate an extremely strong reaction force on the two horizontal positioning clamping frames 42 during operation. If a special structure such as the third slide bar 421, the slide sleeve 422 and the inclined second connecting rod 423 is not provided, this reaction force will inevitably push the horizontal positioning clamping frame 42 upward as shown in the figure. Since the upper end of the horizontal positioning clamping frame 42 is installed on the frame 41, the horizontal positioning clamping frame 42 can only move horizontally and cannot move up and down, so this upward force will inevitably damage the horizontal positioning clamping frame 42 or the slide rail assembly or the frame 41, which greatly reduces the service life of the equipment and also causes a reduction in positioning accuracy. In order to solve this technical problem, after many tests and demonstrations, the present invention further sets up a special structure of a third sliding rod 421, a sliding sleeve 422 and an inclined second connecting rod 423. This structure can effectively counteract the upward reaction force generated by the running wheel 91 on the horizontal positioning clamping frame 42, thereby greatly extending the service life of the equipment and ensuring the implementation of high-precision positioning.

[0084] Furthermore, in a preferred embodiment, the drive assembly 45 includes two tilted drive cylinders 451, each mounted corresponding to a horizontal positioning clamping frame 42. The lower end of the drive cylinder 451 is hinged to the horizontal positioning clamping frame 42, and the upper end is hinged to the frame 41. Providing two drive cylinders 451 for separate driving provides greater clamping force, ensuring precise positioning. Furthermore, due to the unique structure of the tilted second connecting rod 423, the tilted arrangement of the drive cylinders 451 further counteracts the upward reaction force of the running wheel 91 on the horizontal positioning clamping frame 42, achieving even better results.

[0085] Furthermore, in a preferred embodiment, the positioning guide sleeve 43 includes a positioning groove 431 for clamping and positioning the running wheel 91, and the groove portion of the positioning groove 431 is provided with two guide plates 432 arranged obliquely, which are used to form a trumpet-shaped guide groove to guide the running wheel 91 into the positioning groove 431 when clamping; a vertical mounting plate 433 is fixed in the positioning groove 431, and a guide sleeve 434 is provided on the mounting plate 433, and a movable guide rod 435 is horizontally passed through the guide sleeve 434, and a vertical positioning clamping plate 436 is provided on one end of the guide rod 435 close to the groove of the positioning groove 431, and a limit plate 437 is provided on the other end of the guide rod 435. The horizontal sensing component 44 is provided at the tail end of the positioning groove 431. During operation, the inserted running wheel 91 gradually pushes the positioning clamping plate 436 into the positioning groove 431, which is used to make the limit plate 437 gradually approach and contact the horizontal sensing component 44 to send out a sensing signal. In a preferred embodiment, a second elastic member 438 is provided on the guide rod 435 between the positioning card plate 436 and the guide sleeve 434 to cushion the squeezed positioning card plate 436 and to restore the positioning card plate 436 under elastic recovery after the operation is completed.

[0086] Because the pile mold 9 is very long and is constantly being transported, the running wheel 91 on the pile mold 9 may not be exactly centered on the positioning guide sleeve 43, resulting in a positioning problem in the direction of arrows AB in the figure. To address this technical problem, the present invention further provides two guide plates 432 to form a trumpet-shaped guide slot. As the positioning guide sleeve 43 approaches the running wheel 91, it gradually guides the running wheel 91 and ultimately guides it into the positioning slot 431 for clamping. During this guiding movement, the frame 41 undergoes translational sliding, ultimately clamping the running wheel 91 into the positioning slot 431, achieving extremely precise positioning. This not only solves the positioning problem in the direction of arrows CD, but also addresses the positioning problem in the direction of arrows AB, resulting in extremely high positioning accuracy.

[0087] In this embodiment, a second elastic member 438 (a spring in this embodiment) is sleeved on the guide rod 435 between the positioning plate 436 and the guide sleeve 434. This member serves to cushion the squeezed positioning plate 436 (this cushioning prevents rapid, hard contact, extending the service life of the positioning plate 436, the running wheel 91, the positioning guide sleeve 43, and even the horizontal positioning clamping frame 42). Furthermore, it serves to elastically restore the positioning plate 436 after the operation is completed. This structural approach is not only simple and compact, but also highly stable, enabling efficient utilization of the space within the positioning slot 431. In this embodiment, an elastic member is also provided on the side of the positioning plate 436 facing the running wheel 91 to cushion the squeezed running wheel 91.

[0088] like Figures 18 to 21As shown, further, in a preferred embodiment, the fastening and disassembly device 5 includes a rotation drive mechanism 52 and a lifting drive mechanism 53. The driving end of the rotation drive mechanism 52 is fixedly connected to the top of the vertically arranged transmission spline rod 541. The transmission spline rod 541 is provided with a transmission spline sleeve 542 for transmission matching. The bottom end of the transmission spline sleeve 542 is fixed with a sleeve assembly 55 for performing forward and reverse rotation through the transmission spline rod 541 and the transmission spline sleeve 542 under the forward and reverse drive of the rotation drive mechanism 52. The lower part of the transmission spline sleeve 542 is on the upper end of the sleeve assembly 55. The square sleeve is equipped with a bearing assembly 545. The central movable sleeve of the transmission spline sleeve 542 is equipped with an impact hammer 56. The driving end of the lifting drive mechanism 53 is connected to the impact hammer 56. A third elastic member 57 is also sleeved on the transmission spline sleeve 542 between the bearing assembly 545 and the impact hammer 56. During operation, the lifting drive mechanism 53 drives the impact hammer 56 downward and compresses the third elastic member 57, which is used to cause the third elastic member 57 to compress the bearing assembly 545, thereby driving the transmission spline sleeve 542 downward and continuously pressing the sleeve assembly 55 against the bolts of the pile mold 9 to perform bolt tightening and disassembly operations. The specific implementation principle is as follows:

[0089] Taking the bolt removal operation as an example, when the fastening and removal device 5 receives a horizontal positioning signal, the rotary drive mechanism 52 drives the transmission spline rod 541 to rotate forward, causing the transmission spline sleeve 542 on the transmission spline rod 541 to rotate, and in turn, the sleeve assembly 55 at the bottom end of the transmission spline sleeve 542 to rotate. At the same time, the lifting drive mechanism 53 drives the impact hammer 56 downward, causing the impact hammer 56 to press the third elastic member 57 below, which in turn presses the bearing assembly 545 below. At this time, the bearing assembly 545 inevitably drives the rotating transmission spline sleeve 542 downward, ultimately causing the sleeve assembly 55 at the bottom end of the transmission spline sleeve 542 to rotate and descend to approach the bolt of the pipe pile mold 9 below. Ultimately, the rotation and descent enable the sleeve assembly 55 to actively "find" the bolt head and finally firmly enclose the bolt head. At the same time, the lifting drive mechanism 53 continues to drive downward, causing the sleeve assembly 55 to not only nest within the bolt head but also exert downward pressure on the bolt head, effectively "pressing" the sleeve assembly 55 against the bolt in the pile mold 9. This pressure allows the sleeve assembly 55 to impart excellent rotational torque to the bolt, allowing even the most secure bolt to be easily removed. During the removal process, the bolt will inevitably rise, but the special arrangement of the third elastic member 57 allows the bolt to be squeezed upward and eventually exit the screw hole.

[0090] The bolt tightening operation is similar: first pre-install the bolt in the screw hole of the pipe pile mold 9 (not fully tightened), and then transport the pipe pile mold 9 to the bottom of the present invention. When the fastening and disassembly device 5 receives the horizontal positioning signal, the rotation drive mechanism 52 drives the transmission spline rod 541 to rotate in the opposite direction, and the lifting drive mechanism 53 drives the impact hammer 56 to move downward, and finally the sleeve assembly 55 is "pressed" on the bolt of the pipe pile mold 9 to transmit excellent rotational torque, thereby tightly tightening the bolt to be installed on the pipe pile mold 9.

[0091] Through the above special scientific design, it has the following technical advantages:

[0092] First, the fastening and disassembling device 5 of the present invention has a high level of automation. It can realize both bolt fastening and bolt disassembly operations through forward and reverse rotation, which greatly improves work efficiency and greatly reduces labor costs and production risks.

[0093] Secondly, the fastening and disassembly device 5 of the present invention cooperates with and complements each other through the design of the rotating drive mechanism 52, the lifting drive mechanism 53, the transmission spline rod 541, the transmission spline sleeve 542, the impact hammer 56, the third elastic member 57, the bearing assembly 545, the sleeve assembly 55 and other components. The sleeve assembly 55 actively "finds" the bolt head by rotating and descending, and finally firmly "sleeves" on the bolt, so that the sleeve assembly 55 can transmit excellent rotational torque to the bolt. This allows the rotating drive mechanism 52 to operate without the use of a high-power, high-noise drive device like a blaster, greatly reducing noise pollution. At the same time, the excellent tightening and loosening effect is very convenient for the subsequent mold centrifugal operation and demolding operation to proceed normally.

[0094] Third, the fastening and disassembling device 5 of the present invention has the following features: since the sleeve assembly 55 is firmly "pressed" on the bolt, a downward pressure is applied to the bolt head while the knob is turned, so there will be no "machine tripping" phenomenon, no damage to the sleeve assembly 55 or the bolt, and the service life of the equipment is extended.

[0095] Furthermore, in a preferred embodiment, an impact baffle 58 is fixed to the transmission spline sleeve 542 above the impact hammer 56. When the bolt tightening and removal operation is completed and the lifting drive mechanism 53 stops driving the impact hammer 56 downward, the impact hammer 56, under the elastic recovery action of the third elastic member 57, quickly retreats upward and strikes the impact baffle 58, thereby shaking out the bolt within the sleeve assembly 55. Because the third elastic member 57 has been severely compressed during the operation, once the lifting drive mechanism 53 stops driving the impact hammer 56 downward, the impact hammer 56 no longer applies force to the third elastic member 57. At this time, under the elastic recovery action of the third elastic member 57, the impact hammer 56 is quickly pushed downward, causing the impact hammer 56 to quickly strike the impact baffle 58 above, thereby generating vibration, thereby shaking out the bolt that may have been trapped and stuck in the sleeve assembly 55. That is, the impact baffle 58 is used to produce an impact cooperation with the automatically retracted impact hammer 56, thereby effectively solving the problem of the bolt being stuck in the sleeve assembly 55. It not only facilitates the sleeve assembly 55 to quickly carry out the next batch of operations, but also automatically disengages without manual intervention, greatly reducing labor costs, improving work efficiency, and eliminating possible safety hazards in production.

[0096] Furthermore, in a preferred embodiment, a top mounting plate 51 is provided above the transmission spline rod 541. The top mounting plate 51 is fixedly connected to the movable positioning frame 2. The rotation drive mechanism 52 and the lifting drive mechanism 53 are both fixed to the top mounting plate 51. The lifting drive mechanism 53 includes two vertically arranged cylinders, one on each side of the transmission spline rod 541, with the downward-facing drive ends of the two cylinders connected to the impact hammer 56 to provide left and right support for the impact hammer 56 and simultaneously drive the impact hammer 56. The provision of the top mounting plate 51 not only facilitates the installation of the rotation drive mechanism 52 and the lifting drive mechanism 53, but also provides excellent downward driving force for the impact hammer 56, thereby achieving excellent tightening and loosening operations; it also ensures the stability of the impact hammer 56 during the retraction and impact.

[0097] Furthermore, in a preferred embodiment, a retractable dustproof tube 546 is mounted on the transmission spline sleeve 542 between the impact baffle 58 and the drive end of the rotary drive mechanism 52. Because the transmission spline sleeve 542 must be lowered, the upper end of the transmission spline rod 541 is inevitably exposed during this descent. The provision of the retractable dustproof tube 546 protects against dust and contamination. In a preferred embodiment, the third elastic member 57 comprises a buffer spring, which is mounted on the transmission spline sleeve 542.

[0098] Furthermore, in a preferred embodiment, a small base tube 543 with an upper opening is fixed to the top of the bearing assembly 545, and a large base tube 561 with a lower opening is fixed to the bottom of the impact hammer 56, which is configured to nest with the small base tube 543. The third elastic member 57 is mounted within the cavity formed by the small base tube 543 and the large base tube 561. This allows the third elastic member 57 to maintain its vertical compression limit when compressed, thereby ensuring excellent pressure transmission during downward pressure and excellent elastic recovery force during retraction.

[0099] Furthermore, in a preferred embodiment, the rotary drive mechanism 52 includes a hydraulic motor. Due to the special structural arrangement of the present invention, the operation can be performed using only a hydraulic motor, which is highly efficient and compact, greatly reducing noise pollution and maintenance costs.

[0100] Furthermore, in a preferred embodiment, a downwardly protruding mounting rod 5411 is provided at the bottom end of the transmission spline rod 541. An oil scraper 5412 is provided at the bottom end of the mounting rod 5411. A storage space is formed between the oil scraper 5412 and the bottom end of the transmission spline rod 541. An oil nipple 547 is provided on the lower sidewall of the transmission spline sleeve 542 for injecting lubricating oil into the storage space. The provision of the oil scraper 5412 and the oil nipple 547 ensures excellent sliding and lifting coordination between the transmission spline rod 541 and the transmission spline sleeve 542.

[0101] Furthermore, in a preferred embodiment, the bottom end of the transmission spline sleeve 542 is provided with an opening for inserting the sleeve assembly 55. The side wall of the bottom end of the transmission spline sleeve 542 is also provided with an insertion hole, in which a pin shaft 544 is provided for inserting the sleeve assembly 55 to fix the sleeve assembly 55 to the bottom end of the transmission spline sleeve 542. This allows the sleeve assembly 55 to be detachably mounted on the bottom end of the transmission spline sleeve 542, facilitating replacement and maintenance of the sleeve assembly 55.

[0102] Furthermore, in a preferred embodiment, a limit slide assembly 511 is provided on one side of the transmission spline rod 541, parallel to the transmission spline sleeve 542. The upper end of the limit slide assembly 511 is fixedly connected to the movable positioning frame 2. A matching vertical limit rail and limit slider are provided on the limit slide assembly 511. The limit slider is fixedly connected to one end of the impact hammer 56 and is used to limit the lifting and lowering stroke of the impact hammer 56. The provision of the limit slide assembly 511 ensures the stability of the impact hammer 56 during descent, thereby ensuring the stability of the transmission spline sleeve 542 as it rotates while descending, greatly facilitating subsequent precise "finding" and tightening of the bolts. Furthermore, the limit slide assembly 511 stabilizes and protects the impact hammer 56 when it rapidly impacts the impact baffle 58 above, thereby ensuring excellent structural stability for the entire product.

[0103] Although the present invention has been disclosed above with reference to preferred embodiments, this is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the scope of protection of the technical solution of the present invention.
