Description

Technical Field

[0001] The present invention mainly relates to the field of production and manufacturing of pipe piles, and particularly relates to a vertical positioning device for pipe pile molds. Background Art

[0002] In current construction operations, a large number of pipe piles are required. When manufacturing pipe piles, pipe pile molds are used, and the pipe pile molds can be reused multiple times. The pipe pile mold includes an upper mold cover and a lower mold cover, and the two are fastened together with a plurality of studs after being closed. After the mold is used once, cement residues will remain at the joint where the two mold covers meet. If these cement residues are not cleaned up in time, it will affect the subsequent reuse of the mold, and then affect the production quality of the next batch of pipe piles, and may even cause a major risk of safety accidents in subsequent construction.

[0003] Therefore, in the production of pipe piles, the pipe pile mold is used for multiple and different operations: for example, tightening operations of bolts on the pipe pile mold to facilitate subsequent concrete centrifugation during mold closing; for example, transporting the centrifugally formed pipe piles with the mold for curing operations; for example, disassembling the bolts on the pipe pile mold before demolding operations to facilitate demolding and transporting the finished pipe piles; for example, subsequent cleaning operations on the pipe pile mold, etc. In this series of different operation processes, many current operations are manual, which not only results in low work efficiency, high labor costs, high production risks, but also low automation level. In order to improve the automation level, a batch of automation equipment needs to be manufactured to complete the above different operations. However, in automated operations, it is necessary to first position the pipe pile mold during transmission. Only by ensuring accurate positioning can other tooling (such as bolt tightening devices, bolt disassembling devices, mold cleaning devices, etc.) perform subsequent accurate automated operations on the pipe pile mold during transmission; and during this positioning process, it is necessary to ensure that the pipe pile mold does not stop transmitting, so as to truly achieve a significant improvement in work efficiency, a significant reduction in labor costs, and a significant reduction in production risks. Therefore, it is very necessary to invent a device that can automatically position the pipe pile mold during transmission. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a vertical positioning device for pipe pile molds that has a simple and compact structure, is easy to manufacture and maintain, has a high automation level, can greatly improve work efficiency, can greatly reduce labor costs, and can automatically position the pipe pile mold during transmission.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A vertical positioning device for a pipe pile mold cooperates with the pipe pile mold in transmission, comprises a telescopic mechanism and a positioning rod, the positioning rod is connected to the driving end of the telescopic mechanism, the positioning rod is provided with a positioning hook protruding toward the pipe pile mold, the positioning hook is slidably arranged on the positioning rod along the transmission direction of the pipe pile mold, and a sensing component is also provided on the positioning rod near the positioning hook, which is used to send out a sensing signal when the positioning hook slides. During the positioning operation, the telescopic mechanism extends and drives the positioning rod to move toward the pipe pile mold in transmission, so that the positioning hook hooks the running wheel on the pipe pile mold and is driven by the pipe pile mold to slide, so that the sensing component sends out a sensing signal.

[0007] As a further improvement of the present invention, the positioning rod is hollow and a slide groove is provided on the rod body. The positioning hook includes a movable part and a convex hook part connected to each other. The movable part can be slidably arranged in the positioning rod and the convex hook part protrudes outward through the slide groove.

[0008] As a further improvement of the present invention, an elastic member in contact with the moving part is provided at the front end of the moving part in the positioning rod, which is used to buffer the positioning hook when the positioning hook is driven by the pipe pile mold to slide forward, and to make the positioning hook slide backward to reset under the action of elastic recovery after the operation is completed.

[0009] As a further improvement of the present invention, the sensing component includes a sensor and a sensing plate arranged in the positioning rod, the sensing plate is fixed to the rear end of the moving part, and the sensor is arranged behind the sensing plate and is used to send a sensing signal when the sensing plate is separated from the sensor.

[0010] As a further improvement of the present invention, the movable part is provided with more than one limiting waist-shaped hole along the sliding direction, and a limiting rod extending into the limiting waist-shaped hole is fixed on the positioning rod corresponding to each limiting waist-shaped hole to limit the sliding of the movable part.

[0011] As a further improvement of the present invention, the positioning rod is arranged along the transmission direction of the pipe pile mold, and more than two positioning hooks are axially provided on the positioning rod to simultaneously hook more than two running wheels on the pipe pile mold during positioning operations, and each of the positioning hooks is provided with a sensing component.

[0012] As a further improvement of the present invention, the positioning rod is connected to more than two telescopic mechanisms at the same time, and the more than two telescopic mechanisms are arranged in sequence along the axial direction of the positioning rod and are used to drive the positioning rod at the same time to make the positioning rod move smoothly.

[0013] As a further improvement of the present invention, the telescopic mechanism includes a mounting frame, a telescopic driving assembly, and two telescopic limiting rods. The telescopic driving assembly is fixed on the mounting frame and connects the telescopic driving end with the positioning rod. The two telescopic limiting rods are respectively arranged in parallel on both sides of the telescopic driving assembly. One end of each telescopic limiting rod is fixedly connected with the positioning rod, and the other end of each telescopic limiting rod movably penetrates through the vertical bearing seat on the mounting frame to limit the movement of the positioning rod.

[0014] As a further improvement of the present invention, it further includes a horizontal maintaining mechanism for keeping the positioning rod in a horizontal state during movement. The horizontal maintaining mechanism includes a first sliding rod, a first slider, two connecting rods, two second sliding rods, two second sliders, and two springs. The first sliding rod is arranged along the telescopic direction of the telescopic mechanism, and the first slider is slidably arranged on the first sliding rod; the two second sliding rods are both fixed on the positioning rod along the axial direction of the positioning rod and are respectively arranged on the left and right sides of the first sliding rod, and a second slider is arranged on each second sliding rod; the lower ends of the two connecting rods are respectively hinged to a second slider, and the upper ends are both hinged to the first slider; a spring is sleeved on each second sliding rod to gradually compress the spring by the second slider during the telescopic driving process of the telescopic mechanism.

[0015] As a further improvement of the present invention, it further includes a moving frame. A translation assembly is provided on the moving frame and is installed on an external mechanism so that the moving frame can move along the transmission direction of the pipe pile mold. The telescopic mechanism and the horizontal maintaining mechanism are both fixedly installed on the moving frame.

[0016] Compared with the prior art, the advantages of the present invention are as follows:

[0017] First, the vertical positioning device for the pipe pile mold of the present invention, by setting the telescopic mechanism, positioning rod, positioning hook, and induction component in cooperation, can be flexibly installed on the upper, lower, left, and right working surfaces of the pipe pile mold, and can be docked with various automated operation devices. Then, the pipe pile mold is automatically positioned by using the running wheels, and excellent positioning signals are provided, facilitating the automated operation of the automated operation devices, greatly improving the work efficiency and greatly reducing the labor cost.

[0018] Second, for the vertical positioning device of the pipe pile mold of the present invention, an elastic member in contact with the moving part is provided at the front end of the positioning rod inside the rod. The elastic member has two special functions: First, when the positioning hook is driven by the pipe pile mold to slide forward, the front end of the moving part will gradually squeeze the elastic member, forming a buffer for the moving part, that is, the positioning hook, so that the moving part will not hit the end of the positioning rod. In this process, it is convenient for the automated operation equipment to perform rapid automated operations. Second, once the operation is completed, the telescopic mechanism drives the positioning rod to rise, so that it is disengaged from the first running wheel; after disengagement, the moving part slides backward under the elastic recovery action of the elastic member to reset to the induction component, facilitating the next positioning induction operation.

[0019] Third, for the vertical positioning device of the pipe pile mold of the present invention, the cooperation of the limit waist-shaped hole and the limit rod, that is, the front and rear movement stroke of the moving part is limited, has two special functions: First, the stroke is limited, so that the moving part will not violently impact back and forth, and thus will not damage the elastic member in front, nor will it damage the sensor behind during reset. Second, it can limit the sliding of the moving part, making the movement accurate and facilitating the realization of accurate positioning.

[0020] Fourth, for the vertical positioning device of the pipe pile mold of the present invention, in order to further ensure the level of the positioning rod, a horizontal holding mechanism is provided. When the telescopic mechanism drives the positioning rod to gradually descend, the spring 6 will squeeze the second slider outward, and then make the two connecting rods synchronously maintain the state of being tightly supported outward. Finally, through the two connecting rods, the positioning rod is maintained in an excellent horizontal state, improving the accuracy of positioning.

[0021] Fifth, for the vertical positioning device of the pipe pile mold of the present invention, by setting the moving frame 6, the telescopic mechanism can drive the positioning rod to perform left and right translation. During this translation process, the operation time is increased, facilitating the automated operation of the bolt disassembling machine on the pipe pile mold below. Once the operation is completed, the moving frame 6 translates backward and returns to the original position, thereby facilitating the second positioning operation, that is, further ensuring that multiple operations can be sequentially performed without stopping the transmission operation of the pipe pile mold, greatly improving the operation efficiency.

[0031] The following will further describe the present invention in detail with reference to the specification drawings and specific embodiments.

[0032] As Figures 1 to 7 shown, the present invention provides a vertical positioning device for a pipe pile mold, which cooperates with the pipe pile mold 9 in transmission, including a telescopic mechanism 1 and a positioning rod 2. The positioning rod 2 is connected to the driving end of the telescopic mechanism 1, and a fixing component is provided at the other end of the telescopic mechanism 1 for fixing the telescopic mechanism 1. A positioning hook 3 protruding towards the pipe pile mold 9 is provided on the positioning rod 2. The positioning hook 3 is slidably arranged on the positioning rod 2 along the transmission direction of the pipe pile mold 9. An induction assembly 4 is also provided near the positioning hook 3 on the positioning rod 2 to emit an induction signal when the positioning hook 3 slides. During the positioning operation, the telescopic mechanism 1 extends and drives the positioning rod 2 to move towards the pipe pile mold 9 in transmission, so that the positioning hook 3 hooks the running wheel 91 on the pipe pile mold 9 and is driven to slide by the pipe pile mold 9, so that the induction assembly 4 emits an induction signal. The specific implementation principle is as follows:

[0033] The vertical positioning device of the present invention can be installed on a variety of different operating devices for cooperative use. For example, when installed on a bolt disassembly machine, first use the present vertical positioning device to position the pipe pile mold 9 during transmission. After the induction component 4 emits an induction signal, the bolt disassembly machine performs bolt disassembly operations on the positioned pipe pile mold 9 during transmission. For another example, it can be installed on a bolt tightening machine to tighten the bolts of the upper mold cover and the lower mold cover after positioning. It can also be other automated equipment, as long as the vertical positioning device of the present invention is used for positioning first. For example, when installed on a bolt disassembly machine, the telescopic mechanism 1 can be fixed on the frame of the bolt disassembly machine by using the fixing component. A transfer flat car is arranged below the frame for transporting the pipe pile mold 9. The telescopic mechanism 1 drives the positioning rod 2 to descend towards the lower part for positioning operations on the pipe pile mold 9 being transmitted below. Of course, in other embodiments, the vertical positioning device does not necessarily have to be installed directly above the pipe pile mold 9 being transmitted. It can also be installed on the left and right sides of the pipe pile mold 9 being transmitted to extend for positioning operations on the pipe pile mold 9. Even in other embodiments, when the pipe pile mold 9 is transported by top suspension, the vertical positioning device of the present invention can also be installed directly below the pipe pile mold 9 being transmitted for positioning operations on the pipe pile mold 9 being transmitted above. The present invention does not limit the use in different application scenarios. The following takes the vertical positioning device of the present invention installed directly above the pipe pile mold 9 being transmitted as an example in combination with the specification drawings. In this embodiment, it is assumed that the vertical positioning device of the present invention is installed on a bolt disassembly machine:

[0034] Since the pipe pile mold 9 is very long and is provided with a plurality of running wheels 91 arranged at equal intervals. Therefore, each running wheel 91 can be used as a positioning reference point. During operation, the telescopic mechanism 1 drives the positioning rod 2 downward. At this time, the pipe pile mold 9 is transmitted to the lower part of the positioning rod 2, and the first protruding running wheel 91 on the pipe pile mold 9 will contact the positioning hook 3 and drive the positioning hook 3 to slide forward. Once the positioning hook 3 slides, the induction component 4 emits an induction signal. The induction component 4 can be communicatively connected to the central control system on the bolt disassembly machine or directly connected to the disassembly manipulator. At this time, when the bolt disassembly machine receives the signal, it can perform automated operations on the pipe pile mold 9 below. Once the operation is completed, the telescopic mechanism 1 drives the positioning rod 2 to rise so that it disengages from the first running wheel 91. After disengagement, it descends again and is in the vacant position between two running wheels 91. Since the pipe pile mold 9 continues to be transmitted, the second transmitted running wheel 91 hooks the positioning hook 3 again and slides forward, and then the induction component 4 emits an induction signal again for the second operation. And so on in a cycle.

[0035] Through the above special scientific design, it has the following technical advantages:

[0036] The vertical positioning device for a pipe pile mold of the present invention can be flexibly installed on the upper, lower, left, and right working surfaces of the pipe pile mold by providing a cooperating telescopic mechanism 1, positioning rod 2, positioning hook 3, and induction component 4. It can also be docked with various automated working devices, and then the pipe pile mold 9 is automatically positioned by the running wheels 91, thereby providing excellent positioning signals. During the operation process, the pipe pile mold 9 can maintain a transmission state, facilitating the automated operation of the automated working devices, greatly improving work efficiency, and significantly reducing labor costs.

[0037] Further, in a preferred embodiment, the positioning rod 2 is hollow, and a chute is provided on the rod body (in this embodiment, as shown in the figure, the chute is provided on the bottom surface of the positioning rod 2). The positioning hook 3 includes a connected moving part 31 and a convex hook part 32. The moving part 31 is slidably disposed inside the rod of the positioning rod 2, and the convex hook part 32 protrudes outward through the chute. This structural form facilitates the linear movement of the moving part 31 inside the rod, and the overall structure is simple and compact, facilitating installation and manufacture.

[0038] Further, in a preferred embodiment, an elastic member 21 in contact with the moving part 31 is provided at the front end of the moving part 31 inside the rod of the positioning rod 2, which is used to form a buffer for the positioning hook 3 when the positioning hook 3 is driven forward by the pipe pile mold 9 and to make the positioning hook 3 slide backward to reset under the action of elastic recovery after the operation ends. The elastic member 21 has two special functions: First, when the positioning hook 3 is driven forward by the pipe pile mold 9, the front end of the moving part 31 gradually presses the elastic member 21, forming a buffer for the moving part 31, that is, the positioning hook 3, so that the moving part 31 does not impact the end of the positioning rod 2. In this process, it is convenient for the automated working device to perform rapid automated operations. Second, once the operation is completed, the telescopic mechanism 1 drives the positioning rod 2 to rise, so that it is separated from the first running wheel 91; after separation, the moving part 31 slides backward under the action of the elastic recovery of the elastic member 21 to reset to the induction component 4, facilitating the next positioning and induction operation. Of course, in other embodiments, the elastic member 21 may not be provided at the front end of the moving part 31, and it may also be provided at the rear end of the moving part 31 to pull the forward-sliding moving part 31 and pull back the moving part 31 to reset after the operation ends. Such simple position changes should all fall within the protection scope of the present invention.

[0039] Further, in a preferred embodiment, the induction component 4 includes an inductor 41 and an induction plate 42 provided inside the rod of the positioning rod 2. The induction plate 42 is fixed to the rear end of the moving part 31, and the inductor 41 is provided behind the induction plate 42, which is used to emit an induction signal when the induction plate 42 is separated from the inductor 41. Of course, in other embodiments, it can also be set in other forms, such as a position sensor, etc. Such simple position changes should all fall within the protection scope of the present invention.

[0040] Furthermore, in a preferred embodiment, one or more limiting waist-shaped holes 311 are formed in the moving part 31 along the sliding direction. A limiting rod 22 extending into the limiting waist-shaped hole 311 is fixed to the positioning rod 2 corresponding to each limiting waist-shaped hole 311 for slidingly limiting the moving part 31. The cooperation between the limiting waist-shaped hole 311 and the limiting rod 22 limits the forward and backward movement stroke of the moving part 31 and has two special functions: one is to limit the stroke so that the moving part 31 will not violently impact forward and backward, and thus will not damage the elastic part 21 in front, nor will it damage the sensor 41 behind during reset. The other is to be able to limit the sliding of the moving part 31 to make the movement accurate and facilitate the realization of accurate positioning.

[0041] Furthermore, in a preferred embodiment, the positioning rod 2 is arranged along the transmission direction of the pipe pile mold 9. Two or more positioning hooks 3 are provided on the positioning rod 2 along the axial direction for simultaneously hooking two or more running wheels 91 on the pipe pile mold 9 during positioning operations. An induction component 4 is provided at each positioning hook 3. Since the pipe pile mold 9 is very long and is provided with a plurality of running wheels 91 arranged at equal intervals. Therefore, a positioning operation point can be set between every two running wheels 91. By setting two or more positioning hooks 3 to simultaneously hook two or more running wheels 91 on the pipe pile mold 9 and having the plurality of induction components 4 corresponding to the two or more positioning hooks 3 all emit signals before operating, the positioning accuracy is further improved and operation errors are avoided. Second, an operation point can be exactly formed between two adjacent running wheels 91, and automated operations can be carried out section by section, with better effects and higher efficiency.

[0042] Furthermore, in a preferred embodiment, the positioning rod 2 is simultaneously connected to two or more telescopic mechanisms 1. The two or more telescopic mechanisms 1 are arranged in sequence along the axial direction of the positioning rod 2 and are used to simultaneously drive the positioning rod 2 to make the movement of the positioning rod 2 stable. In this embodiment, two telescopic mechanisms 1 are provided. Since two or more positioning hooks 3 are provided on the positioning rod 2 along the axial direction and the positioning rod 2 has a certain length. To ensure the horizontal lifting of the positioning rod 2 and thus ensure that each positioning hook 3 can synchronously hook the running wheel 91, and at the same time to ensure that the positioning rod 2 will not shake when the pipe pile mold 9 drives the positioning hook 3 to move, two telescopic mechanisms 1 are set to move synchronously. One is to ensure the horizontal and stability of the positioning rod 2 structurally, and the other is to ensure the horizontal lifting of the positioning rod 2 in terms of driving actions.

[0043] Further, in a preferred embodiment, the telescopic mechanism 1 includes a mounting frame 11, a telescopic driving assembly 12, and two telescopic limiting rods 13. The telescopic driving assembly 12 is fixed on the mounting frame 11 and its telescopic driving end is connected to the positioning rod 2. The two telescopic limiting rods 13 are respectively arranged in parallel on both sides of the telescopic driving assembly 12. One end of each telescopic limiting rod 13 is fixedly connected to the positioning rod 2, and the other end of each telescopic limiting rod 13 movably passes through a vertical bearing seat on the mounting frame 11 for limiting the movement of the positioning rod 2. The mounting frame 11 can be directly mounted on the frame of the automation equipment through a fixing component. Then, telescopic driving is performed through the telescopic driving assembly 12. At the same time, in order to ensure the horizontal lifting of the positioning rod 2 and to ensure that the positioning rod 2 does not shake when the positioning hook 3 moves, two telescopic limiting rods 13 are further provided. The two telescopic limiting rods 13 can further ensure the horizontal lifting of the positioning rod 2 and can also further ensure the stability of the positioning rod 2.

[0044] Further, in a preferred embodiment, a horizontal holding mechanism 5 for keeping the positioning rod 2 in a horizontal state during movement is further included. The horizontal holding mechanism 5 includes a first slide rod 51, a first slider 52, two connecting rods 53, two second slide rods 54, two second sliders 55, and two springs 56. The first slide rod 51 is arranged along the telescopic direction of the telescopic mechanism 1, and the first slider 52 is slidably arranged on the first slide rod 51. The two second slide rods 54 are both fixed on the positioning rod 2 along the axial direction of the positioning rod 2 and are respectively arranged on the left and right sides of the first slide rod 51. A second slider 55 is arranged on each second slide rod 54. The lower ends of the two connecting rods 53 are respectively hinged to a second slider 55, and the upper ends are both hinged to the first slider 52. A spring 56 is sleeved on each second slide rod 54 for gradually squeezing the spring 56 by the second slider 55 during the driving process of the telescopic mechanism 1 extending. Since there are more than two positioning hooks 3 arranged along the axial direction on the positioning rod 2, the positioning rod 2 has a certain length. In order to further ensure the horizontal of the positioning rod 2, the horizontal holding mechanism 5 is provided. As Figure 2 , Figure 3 shown, when the telescopic mechanism 1 drives the positioning rod 2 to gradually descend, under the pulling action of the connecting rod 53, the first slider 52 first descends along the first slide rod 51. When the first slider 52 descends in place, since the positioning rod 2 continues to descend, the lower ends of the two connecting rods 53 gradually approach each other, and at this time the two second sliders 55 will also gradually approach each other. During this process, the two second sliders 55 will gradually squeeze the spring 56 inward, that is, the spring 56 will squeeze the second slider 55 outward, thereby making the two connecting rods 53 synchronously maintain a state of being tightened outward, and finally making the positioning rod 2 maintain an excellent horizontal state through the two connecting rods 53, improving the positioning accuracy.

[0045] Furthermore, in a preferred embodiment, it further includes a moving frame 6. A translation assembly is provided on the moving frame 6 and is installed on an external mechanism (i.e., the bolt dismounting machine in this embodiment) for enabling the moving frame 6 to move along the transmission direction of the pipe pile mold 9. The telescopic mechanism 1 and the horizontal holding mechanism 5 are both fixedly installed on the moving frame 6. By providing the moving frame 6, the telescopic mechanism 1 can drive the positioning rod 2 to perform left and right translation. For example, when the first protruding running wheel 91 on the pipe pile mold 9 contacts the positioning hook 3 and drives the positioning hook 3 to slide forward, at this time the sensing assembly 4 emits a sensing signal, and at the same time the pipe pile mold 9 also drives the positioning rod 2 to move forward synchronously through the moving frame 6. During this translation process, the operation time is increased, which is convenient for the bolt dismounting machine to perform automated operations on the lower pipe pile mold 9. Once the operation is completed, the moving frame 6 translates backward and returns to the original position, thereby facilitating the development of the second positioning operation, that is, further ensuring that multiple operations can be sequentially performed without stopping the transmission operation of the pipe pile mold 9, greatly improving the operation efficiency. Of course, in this embodiment, the vertical positioning device of the present invention itself is provided with the moving frame 6. In other embodiments, if the external mechanism (i.e., the bolt dismounting machine in this embodiment) itself is provided with a translation mechanism, then the vertical positioning device of the present invention does not need to be provided with the moving frame 6, and only needs to directly fix the vertical positioning device of the present invention on the translation mechanism of the external mechanism and translate along with the external mechanism.

[0046] Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes, without departing from the scope of the technical solution of the present invention. 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.
