Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated pile production, and in particular to an adjustment device for prefabricated pile mold closing, a mold closing system and a mold closing method. Background Art

[0002] Precast concrete piles are prefabricated components that are prefabricated in molds in factories and then transported to construction sites for use. They are widely used in infrastructure construction such as buildings, roads, and docks due to their superior performance. At present, the main production process of high-strength precast concrete piles in factories is: batching → mixing → laying → mold closing → prestressing tensioning → centrifugal molding → pouring residual slurry → normal pressure steam curing → demoulding → high pressure steam curing → finished product; or, first close the mold and then lay the material.

[0003] Among them, in order to facilitate the placement and demolding of the concrete precast piles in the forming mold, the forming mold of the concrete precast piles usually includes a matching upper mold and a lower mold. In the process of mold closing, the alignment of the upper mold and the lower mold is generally determined manually, and the upper mold usually needs to be moved to make the upper mold and the lower mold match accurately. After the upper mold and the lower mold are closed, they are fastened and fixed by the mold bolts. However, due to the lack of effective and precise positioning, multiple repeated operations are required during the mold closing process to correct the mold closing position, which seriously affects the production efficiency of the concrete precast piles. If the operator does not carefully observe and fail to find the small errors in the matching of the upper mold and the lower mold, the mold bolts will be skewed, which will seriously affect the alignment of the subsequent mold closing machine's air gun head with the mold bolts, thereby easily damaging the mold bolts and / or air gun heads, resulting in increased production costs and affecting production efficiency. Summary of the invention

[0004] In order to solve the technical problem that the existing upper mold and lower mold cannot be accurately positioned when they are molded, the present invention provides an adjustment device for prefabricated pile molds, a mold system and a mold method, so as to achieve accurate positioning of the upper mold and lower mold when they are molded.

[0005] To achieve the purpose of the present invention, the present invention adopts the following technical solutions:

[0006] A prefabricated pile mold adjustment device is located in the mold area and includes: a jacking mechanism, a transverse mechanism and a measurement and control device. The transverse mechanism is arranged on the jacking mechanism.

[0007] The measurement and control device includes: a first sensor located in the mold closing area for monitoring the position of the upper mold, a second sensor located in the mold closing area for monitoring the position of the lower mold, and a controller electrically connected to the first sensor and the second sensor. The controller controls the operation of the lifting mechanism and / or the transverse mechanism with reference to the position of the upper mold so that the lower mold on the transverse mechanism moves to align with the upper mold to achieve accurate mold closing; wherein the first sensor is located next to the second sensor.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: the adjustment device of the present invention monitors the positions of the upper mold and the lower mold respectively through the first sensor and the second sensor, and then controls the operation of the lifting mechanism and / or the transverse movement mechanism according to the monitored information through the controller, so that the lower mold on the transverse movement mechanism moves to the point where the monitoring data of the first sensor and the second sensor are the same, and at this time the upper mold and the lower mold are aligned, that is, the present invention can control the moving distance of the lower mold according to the data of the first sensor and the second sensor, so that the upper mold and the lower mold can be aligned by moving the lower mold once, thus avoiding repeated operations of the upper mold during existing manual operations, thereby improving efficiency. In addition, the present invention adjusts the position of the lower mold through the adjustment device, so that the upper mold and the lower mold can be accurately aligned, thus avoiding problems such as damage to the mold bolts and / or blasting heads due to misalignment of the upper mold and the lower mold during subsequent mold closing, thereby improving production efficiency and controlling production costs.

[0009] In addition, the present invention also provides a mold clamping system, the specific scheme is as follows:

[0010] A mold clamping system comprises two parallel left and right conveyor chains and the aforementioned precast pile mold clamping adjustment device, wherein the adjustment device is arranged between the two conveyor chains to adjust the position of the lower mold located in the mold clamping area on the conveyor chains.

[0011] The present invention also provides a mold clamping system including the aforementioned precast pile mold clamping adjustment device, and thus has the same function as the precast pile mold clamping adjustment device, and also has the advantage of making the subsequent mold clamping process more stable due to the stable operation of the upper and lower molds.

[0012] In addition, the present invention also provides a mold closing method, comprising the following steps:

[0013] In the mold conveying step, two parallel conveying chains on the left and right convey the upper mold and the lower mold arranged in sequence at intervals to the mold closing position, and the upper mold is located in front of the corresponding lower mold;

[0014] The upper mold lifting and conveying step, the upper mold adjusting device grabs the upper mold, lifts it and conveys it to the top of the predetermined mold clamping area;

[0015] After the mold closing step and the adjusting device adjust the position of the lower mold with reference to the position of the upper mold, the upper mold adjusting device lowers the upper mold so that the lower mold and the upper mold are accurately matched.

[0016] The mold closing method further provided by the present invention includes the aforementioned precast pile mold closing adjustment device, and thus has the same function as the precast pile mold closing adjustment device, and also has the advantage of making the subsequent mold closing process more stable due to the stable operation of the upper mold and the lower mold.

[0031] See also Figure 1 , Figure 2 , Figure 3 , Figure 1 is a top view of the clamping system of the present invention; Figure 2 is a side view of the clamping system of the present invention; Figure 3 It is a structural schematic diagram of the adjustment device for precast pile mold clamping of the present invention.

[0032] This embodiment provides a mold clamping system, including two parallel left and right conveyor chains 20 and a precast pile mold clamping adjustment device 10, which is arranged between the two conveyor chains 20 to adjust the position of the lower mold 102 located in the mold clamping area 200 on the conveyor chain 20.

[0033] Among them, the adjustment device 10 for precast pile mold clamping includes a lifting mechanism 11, a transverse movement mechanism 12 and a measurement and control device 13.

[0035] The adjusting device 10 of the present invention monitors the positions of the upper mold 101 and the lower mold 102 respectively through the first sensor 132 and the second sensor 133, and then controls the operation of the lifting mechanism 11 and / or the transverse movement mechanism 12 according to the monitored information through the controller 131, so that the lower mold 102 on the transverse movement mechanism 12 moves to the point where the monitoring data of the first sensor 132 and the second sensor 133 are the same. At this time, the upper mold 101 and the lower mold 102 are aligned, that is, the present invention can control the moving distance of the lower mold 102 according to the data of the first sensor 132 and the second sensor 133, so that the upper mold 101 and the lower mold 102 can be aligned by moving the lower mold 102 once, avoiding repeated operations of the upper mold 101 during existing manual operations, thereby improving efficiency. In addition, the present invention adjusts the position of the lower mold 102 by the adjusting device 10, so that the upper mold 101 and the lower mold 102 can be accurately aligned, avoiding problems such as damage to the mold bolts and / or the blast head due to misalignment of the upper mold 101 and the lower mold 102 during subsequent mold closing, thereby improving production efficiency and controlling production costs.

[0057] See also Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Figure 6 3 is a schematic structural diagram of the mold clamping base 30; Figure 7 It is a structural schematic diagram of the deviation correction seat 40; Figure 8 is a side view of the upper die adjustment device 50; Fig. 9 60 is a side view of the mold clamping machine. Compared with the first, second and third embodiments, the mold clamping system provided in this embodiment has the following different structural designs:

[0058] Each conveying chain 20 includes a pile mold input chain 21 and a pile mold output chain 22. The end of the pile mold input chain 21 is connected to the initial end of the pile mold output chain 22. The pile mold input chain 21 is used to convey the upper mold 101 and the lower mold 102 arranged in sequence at intervals. The pile mold output chain 22 is used to convey the pile mold 100 that has been molded. The upper mold 101 and the lower mold 102 to be molded are conveyed separately from the pile mold 100 that has been molded, which is convenient for control.

[0059] Preferably, the pile mold output chain 22 and the pile mold input chain 21 have different running speeds. Since the pile mold input chain 21 conveys the upper mold 101 and the lower mold 102 which are arranged in sequence at intervals, and the pile mold output chain 22 conveys the closed pile mold 100, the pile mold output chain 22 and the pile mold input chain 21 have different conveying intervals, and the pile mold output chain 22 and the pile mold input chain 21 have different running speeds, which facilitates the adjustment and control of the closing system operation.

The deviation correction seat 40 includes left and right limit rollers 41 and a front limit roller 42. A groove 43 is formed between the left and right limit rollers 41 and the front limit roller 42. When the pile mold 100 is conveyed to the deviation correction seat 40, the lower mold 102 is limited in the groove 43 to slow down the conveying speed of the pile mold 100, thereby correcting the tilted pile mold 100 to make it perpendicular to the conveying chain 20. The rear here refers to the direction where the pile mold 100 is conveyed after the mold is clamped.

[0064] The mold clamping system also includes an upper mold adjusting device 50 and a mold clamping machine 60. The upper mold adjusting device 50 and the mold clamping machine 60 are arranged above the mold clamping base 30.

The lifting assembly 51 includes a lifting rod 511, a lifting motor 512 and a moving motor 513. The lifting motor 512 drives the lifting rod 511 to rise and fall, and the moving motor 513 drives the lifting rod 511 to move on the moving rail 52. The mold clamping machine 60 includes a mold clamping frame 61 and a blast mechanism 62 arranged on the mold clamping frame 61. The blast mechanism 62 includes a blast head 621 and a moving shaft 622 that drives the blast head 621 to move up and down. The blast head 621 is used to tighten the mold clamping bolts that fasten the upper mold 101 and the lower mold 102.

[0065] Preferably, the free end of the lifting assembly 51 is provided with a connecting hook 514 connected to the upper mold 101 and a second induction switch 136 electrically connected to the controller 131. When the upper mold 101 touches the second induction switch 136, at the same time, the connecting hook 514 hooks the upper mold 101, and the lifting assembly 51 starts to drive the upper mold 101 to rise. A third induction switch (not shown) is provided on the movable rail 52. When the lifting assembly 51 moves to trigger the third induction switch, the lifting assembly 51 stops moving, and the upper mold 101 is located above the mold base 30 waiting for mold closing. The controller 131 electrically connects the second induction switch 136 and the third induction switch, and controls the lifting and movement of the lifting assembly 51.

[0066] Specifically, when the upper mold 101 touches the second sensing switch 136, the connecting hook 514 of the lifting assembly 51 hooks the upper mold 101, and the controller 131 controls the lifting assembly 51 to drive the upper mold 101 to rise and move on the movable rail 52 until the third sensing switch is triggered and the lifting assembly 51 stops moving. At this time, the upper mold 101 is located above the mold base 30 waiting for mold closing. After the controller 131 controls the lifting assembly 51 to lower the upper mold 101 to the lower mold 102, and after the adjustment device 10 adjusts the position of the lower mold 102 to be aligned with the upper mold 101, the controller 131 controls the mold frame 61 of the mold closing machine 60 to move to directly above the mold base 30, and the air gun head 621 moves down to align with the mold bolts of the upper mold 101 and the lower mold 102, and the air gun head 621 is started to tighten the mold bolts.

[0068] In this embodiment, the same parts as those in Embodiments 1, 2, 3 and 4 are given the same figure marks, and the same text descriptions are omitted.

[0069] See also Figure 1-Figure 5 Compared with the first, second, third and fourth embodiments, this embodiment provides a mold closing method, including the following steps:

[0070] In the mold conveying step, two parallel conveying chains 20 on the left and right convey the upper mold 101 and the lower mold 102 arranged in sequence at intervals to the mold closing position, and the upper mold 101 is located in front of the corresponding lower mold 102;

[0071] The upper mold 101 is lifted and transported, and the upper mold adjusting device 50 grabs the upper mold 101, lifts it and transports it to the top of the predetermined mold clamping area 200;

[0072] After the mold closing step and the adjusting device 10 adjusts the position of the lower mold 102 with reference to the position of the upper mold 101 , the upper mold adjusting device 50 lowers the upper mold 101 so that the lower mold 102 and the upper mold 101 are accurately matched.

[0073] Since the lower mold 102 is adjusted by the adjusting device 10 in the mold closing method provided by the present invention, the effect brought by the adjusting device 10 is achieved, that is, the moving distance of the lower mold 102 can be controlled according to the data of the first sensor 132 and the second sensor 133, so that the upper mold 101 and the lower mold 102 can be aligned by moving the lower mold 102 once, thereby avoiding the repeated operation of the upper mold 101 during the existing manual operation, thereby improving efficiency. In addition, the present invention adjusts the position of the lower mold 102 by the adjusting device 10, so that the upper mold 101 and the lower mold 102 can be accurately aligned, thereby avoiding the damage of the mold closing bolts and / or the air gun head 621 due to the misalignment of the upper mold 101 and the lower mold 102 during subsequent mold closing, thereby improving production efficiency and controlling production costs.

[0074] Embodiment 6

[0075] In this embodiment, the same parts as those in Embodiments 1, 2, 3, 4 and 5 are given the same figure marks, and the same text descriptions are omitted.

[0076] See also Figure 1-Figure 9 Compared with the fifth embodiment, the mold clamping method provided in this embodiment has the following different structural designs:

[0077] In the step of lifting the upper mold 101, the upper mold 101 transported by the pile mold input chain 21 triggers the second induction switch 136 at the free end of the lifting assembly 51, and when the connecting hook 514 hooks the upper mold 101, the lifting assembly 51 rises and moves on the moving rail 52. When the lifting assembly 51 moves to trigger the third induction switch, the lifting assembly 51 stops moving, and the upper mold 101 is located directly above the mold base 30 waiting for mold closing.

[0078] In the mold closing step, the lower mold 102 transported by the pile mold output chain 22 triggers the lower mold sensing switch 135, and the controller 131 controls the lifting mechanism 11 and the longitudinal movement mechanism 14 to lift the lower mold 102 on the pile mold input chain 21 and move it to the pile mold output chain 22 and the mold closing seat 30. Then, the controller 131 controls the lifting mechanism 11 and / or the transverse movement mechanism 12 to operate with reference to the position information of the upper mold 101 monitored by the first sensor 132 and the position information of the lower mold 102 monitored by the second sensor 133, so that the lower mold 102 on the transverse movement mechanism 12 moves to align with the upper mold 101. Then, the controller 131 controls the lifting assembly 51 to descend and place the upper mold 101 on the lower mold 102.

[0079] Preferably, the mold closing step further comprises the following steps:

[0080] In the mold clamping and fixing step, the mold clamping machine 60 descends and the air gun head 621 tightens the mold clamping bolts that fasten the upper mold 101 and the lower mold 102;

[0081] In the step of correcting the position of the mold, the pile mold output chain 22 conveys the pile mold 100 to the correction seat 40 , and the correction seat 40 corrects the pile mold 100 .

[0082] Specifically, the whole mold closing process is:

[0083] The pile mold input chain 21 conveys the upper mold 101 and the lower mold 102 arranged in sequence at intervals. When the upper mold 101 to be conveyed touches the second induction switch 136, and the connecting hook 514 has hooked the upper mold 101 at this time, the controller 131 controls the lifting assembly 51 to drive the upper mold 101 to rise and move on the moving rail 52 until the lifting assembly 51 triggers the third induction switch, and the lifting assembly 51 stops moving, so that the upper mold 101 is located above the mold clamping base 30 waiting for mold clamping;

[0084] When the lower mold 102 to be transported triggers the lower mold induction switch 135, the lower mold 102 is located above the transverse movement mechanism 12 at the initial position, and the controller 131 controls the lifting mechanism 11 to rise to make the transverse movement mechanism 12 rise, so that the lower mold 102 on the pile mold input chain 21 is located on the transverse movement mechanism 12, and the controller 131 controls the longitudinal movement mechanism 14 to move. When the longitudinal movement mechanism 14 moves to trigger the first induction switch 134, the controller 131 controls the longitudinal movement mechanism 14 to stop moving. At this time, the lower mold 102 on the transverse movement mechanism 12 is located on the mold clamping seat 30 on one side of the pile mold output chain 22;

[0085] The position of the upper mold 101 is monitored by the first sensor 132, and the position of the lower mold 102 is monitored by the second sensor 133. The first sensor 132 and the second sensor 133 send the monitored information to the controller 131. The controller 131 compares whether the data information sent by the first sensor 132 and the second sensor 133 are consistent. If they are consistent, the controller 131 controls the lifting assembly 51 to drop the upper mold 101, and controls the mold clamping machine 60 to move to the top of the mold clamping seat 30. The air gun head 621 moves down to align with the mold clamping bolts of the upper mold 101 and the lower mold 102, and the air gun head 621 is started. 21, tighten the mold bolts to achieve mold closing; if they are not consistent, the controller 131 controls the transverse movement mechanism 12 to operate, and the controller 131 controls the transverse movement mechanism 12 to move and adjust the distance according to the monitored information, so that the lower mold 102 on the transverse movement mechanism 12 is aligned with the upper mold 101. After the adjustment of the lower mold 102 is completed, the controller 131 controls the lifting assembly 51 to descend and put down the upper mold 101, and controls the mold clamping machine 60 to move to the top of the mold clamping seat 30, and the air gun head 621 moves down to align the mold bolts of the upper mold 101 and the lower mold 102, and starts the air gun head 621 to tighten the mold bolts to achieve mold closing;

[0086] After the mold is closed, the pile mold 100 is transported to the next process by the pile mold output chain 22 , and during the transportation, the pile mold 100 passes through the deviation correction seat 40 and is adjusted by the deviation correction seat 40 .

[0087] In the above-mentioned embodiments 1 to 6, during the mold closing process, the lower mold 102 is adjusted by the adjusting device 10, so that the entire mold closing process is simple and efficient, and the mold closing process is more automated. Some technical implementation methods of embodiments 1 to 6 can be combined or replaced.

[0088] The above are only preferred embodiments of the present invention. The protection scope of the present invention shall be based on the scope defined by the claims. Several improvements and modifications made by those skilled in the art without departing from the spirit and scope of the present invention should also be regarded as the protection scope of the present invention.
