Description

Technical Field

[0001] The invention relates to the technical field of concrete prefabricated part production equipment, and in particular to a formwork platform guiding device suitable for a stacking and destacking machine and a transverse transfer shuttle vehicle. Background Art

[0002] When the prefabricated parts production line is in operation, the mold table is guided by two rows of rollers and moves between the various processes. There are two support beams on both sides of the bottom of the mold table. The support beams are clamped on the working surface of the rollers. The end faces of the rollers are also provided with flanges to prevent the support beams from deviating.

[0003] When the mold table enters the stacking, destacking or transverse movement process, the mold table needs to be lifted to separate the support beam from the roller. After completing the corresponding process, the mold table is put back on the roller. Since the mold table is lifted by the lifting equipment and then put back, there will be errors, causing lateral deviations between the mold table and the roller (when the equipment has been working for a long time or maintenance is not timely, the error will be aggravated). If the deviation exceeds a certain range (the deviation usually cannot exceed 10mm), when the mold table is put back on the roller, the support beam cannot press on the working surface of the roller, but on the flange of the roller. The flange will not play a limiting and guiding role. The mold table will become more and more deviated when moving along the roller, and eventually the mold table will fall off the roller, causing a production accident, which may damage the equipment at the least, or cause casualties at the worst.

[0004] The patent with publication number CN213386334U discloses a die guide device suitable for stacking and destacking machines and transverse shuttle vehicles, including a base, a support roller is arranged on the top of the base, a mounting frame is arranged on the upper side of the base, and a guide roller is arranged on the mounting frame. The steel frame at the edge of the die is pressed on the outer diameter of the guide roller. The horizontal component of the gravity of the die falling on the guide roller is used to make the die move laterally, changing the direction of the die falling from vertical to falling obliquely downward, so as to accurately land on the support roller tread. Since the guide roller on one side of the die can only apply a lateral horizontal force to one side of the die, and the guide roller on the other side cannot apply force to the die, the die is easy to tilt when it falls. In addition, the die will have a large impact force when it falls on the support roller, thereby shortening the service life of the support roller. In addition, its adjustment range is limited, and the deviation can only be relaxed to 15mm. Summary of the invention

[0005] The purpose of the present invention is to provide a formwork platform guiding device suitable for stacking and destacking machines and transverse shuttle vehicles, which can correct the lateral deviation of the formwork platform when the formwork platform falls back onto the rollers and make the formwork platform fall stably onto the rollers to avoid impact on the rollers.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] The cam is connected to the support frame by the sliding sleeve, and the supporting frame is connected with the sliding sleeve by the sliding sleeve, and the supporting frame is connected with the supporting frame by the sliding sleeve.

[0008] Furthermore, the driving mechanism includes a vertical rotating shaft arranged in the support tube, the upper end of the rotating shaft is fixedly connected to the rotating arm, the lower end of the rotating shaft is threadedly connected to the support tube, a second spring is provided between the support tube and the base, and the first spring is sleeved outside the rotating shaft.

[0009] Furthermore, the driving mechanism includes a vertical rotating shaft arranged in a support tube, the upper end of the rotating shaft is rotatably connected to the rotating arm through a one-way transmission member, the lower part of the rotating shaft is a driving head with an external thread, the upper part of the support tube is a threaded hole, the lower part of the support tube is a return hole with a diameter larger than the outer diameter of the driving head, the diameter of the upper part of the rotating shaft is smaller than the inner diameter of the threaded hole, a torsion spring for returning the rotating arm is provided between the rotating arm and the sliding sleeve, and the first spring is sleeved outside the rotating shaft.

[0010] Furthermore, after the support beam is pressed on the support component, it drives the swivel arm and the rotating shaft to move downward, and the rotating shaft is driven to rotate under the action of the driving head and the support tube. The rotating shaft drives the swivel arm to rotate forward through the one-way transmission component, so that the two rollers approach and push the support beam. When the middle position of the support beam is aligned with the support component, the driving head is separated from the upper part of the support tube, and driven by the torsion spring, the swivel arm drives the rotating shaft to rotate in the opposite direction through the one-way transmission component, so that the rollers move away from the support beam, and the support beam falls downward to the working surface of the roller under the mold platform, and the support beam moves along the roller to separate the support beam from the support component. Driven by the first spring, the driving head re-enters the upper part of the support tube, and under the action of the one-way transmission component, the rotating shaft rotates in the opposite direction on the swivel arm.

[0011] Furthermore, the top surface of the sliding sleeve is provided with an arc-shaped limiting groove coaxial with the sliding sleeve, and the bottom surface of the rotating arm is fixedly connected with a limiting pin movable in the limiting groove.

[0012] Furthermore, the lower part of the sliding sleeve is sleeved outside the supporting tube, the lower part of the sliding sleeve is provided with a vertical sliding hole, the sliding hole is provided with a sliding pin that slidably cooperates with the sliding sleeve, and the sliding pin is fixedly connected to the supporting tube.

[0013] Furthermore, the supporting component is a rotating wheel or a bull's eye bearing.

[0014] Furthermore, the one-way transmission member is a one-way bearing or a ratchet.

[0015] The positive effects of the present invention are:

[0016] 1. The present invention is provided with a rotating arm, a sliding sleeve, a support tube and a base. The rotating arm is provided with two rollers and a support component. A first spring is provided between the sliding sleeve and the support tube. A rotating shaft is provided in the support tube. The rotating arm and the sliding sleeve are rotatably connected. When the support beam at the bottom of the mold platform drives the rotating arm to move downward, the rotating arm rotates, and the rollers are used to move the mold platform horizontally to straighten the mold platform, so that the two support beams are aligned with the working surfaces of the corresponding rollers respectively, so that after the mold platform falls, the support beams are accurately pressed onto the working surfaces of the rollers to prevent the mold platform from deviating during subsequent movement. The two rollers on the same rotating arm can straighten the support beam in both directions horizontally. In actual work, the rollers on the four guide devices can simultaneously move the two support beams horizontally, so that the support beams are more evenly stressed and not easily skewed, making it easier to straighten the mold platform. The first spring acts as a buffer, which can slow down the mold platform when it descends and let it fall smoothly onto the roller, reducing the impact on the mold platform and the roller, thereby extending the service life of the roller and keeping the bottom surface of the support beam at the bottom of the mold platform flat, preventing pits from forming on the bottom surface of the support beam due to impact, which would cause the mold platform to be unable to move smoothly along the roller.

[0017] 2. A driving head is provided on the rotating shaft, which is threadedly connected to the support tube. The rotating shaft is connected to the rotating arm through a one-way transmission member. When the support beam is straightened, the driving head can be separated from the support tube, so that the roller is away from the support beam under the action of the torsion spring. Therefore, when the subsequent support beam moves along the roller, it will not be affected by the roller, thereby making the mold table move more smoothly and reducing the wear of the roller.

[0030] like Fig.10 As shown, in normal operation, two support beams 19 at the bottom of the die table 18 are respectively placed on the working surfaces of two rows of rollers 21. The support beams 19 are made of square tubes or other profiles, and their bottom surfaces are flat. A wheel frame 20 is provided on the ground for supporting each roller 21. The inner side of each roller 21 is a flange, which can prevent the die table 18 from being separated from the working surface of the roller 21 when moving, that is, preventing the die table 18 from running off.

[0031] For the convenience of description, in the following description, the setting direction of the support beam 19 is "longitudinal", and the direction perpendicular to the support beam 19 in the horizontal plane is "transverse".

[0032] Example 1

[0033] like Figures 1 to 3As shown, a die guide device suitable for stacking and destacking machines and transverse shuttle vehicles includes a rotating arm 5, a sleeve 3, a support tube 2 and a base 1 which are sequentially arranged from top to bottom below the support beam 19 of the die 18. The middle of the rotating arm 5 is circular, the sleeve 3 and the support tube 2 are both vertically arranged cylindrical, the rotating arm 5 is horizontally arranged, and its top surface is a plane, the middle position of the bottom of the rotating arm 5 is rotatably connected to the sleeve 3 through a thrust bearing, the base 1 and the sleeve 3 are both slidably connected to the support tube 2, and the base 1 and the support tube 2 are splined to prevent the support tube 2 from rotating when moving up and down along the base 1. The top of the rotating arm 5 is provided with a support component 7 for matching with the bottom surface of the support beam 19, and the support component 7 is a bull's eye bearing, so as to facilitate the movement of the support beam 19 on the support component 7 in all directions. The two ends of the rotating arm 5 are rotatably connected with vertical cylindrical rollers 6, and the two rollers 6 are respectively located on both sides of the support beam 19, and the two rollers 6 are higher than the support component 7. A first spring 11 is provided between the sliding sleeve 3 and the support tube 2, and a second spring 16 is provided between the support tube 2 and the base 1. When the compression amount is the same, the elastic force of the first spring 11 is smaller than the elastic force of the second spring 16. A driving mechanism is provided in the support tube 2 for driving the rotating arm 5 to rotate and making the two rollers 6 approach or move away from the two sides of the support beam 19 synchronously.

[0034] The driving mechanism includes a vertical rotating shaft 8 arranged in the support tube 2, the upper end of the rotating shaft 8 is fixedly connected to the rotating arm 5, the rotating shaft 8 is rotatably connected to the sliding sleeve 3 through a bearing, the lower end of the rotating shaft 8 is threadedly connected to the support tube 2, and the first spring 11 is sleeved outside the rotating shaft 8.

[0035] Combination Figures 4 to 8 As shown, in actual use, four guide devices are provided, and the four guide devices are installed in groups of two on the ground below the two support beams 19 at the bottom of the mold platform 18, and each guide device is arranged between two adjacent rollers 21 in the same row.

[0036] In this embodiment, the working process of the present invention is:

[0037] 1. After the process is completed, the die table 18 moves from top to bottom onto the roller 21 driven by the lifting device. The top surface of the support component 7 is higher than the roller 21, so the bottom surface of the support beam 19 will first contact the support component 7.

[0038] 2. The die table 18 moves downward under the action of gravity, and the first spring 11 and the second spring 16 are compressed. Since the rotating shaft 8 and the support tube 2 are threadedly connected, the rotating shaft 8 will rotate, thereby driving the rotating arm 5 to rotate, causing the two rollers 6 to rotate, and moving the support beam 19, so that the support component 7 is against the middle position of the bottom surface of the support beam 19, thereby realizing the straightening of the die table 18. At this time, the inner side of the support beam 19 is located above the inner side of the flange of the roller 21.

[0039] 3. Since the two rollers 6 clamp the bottom of the support beam 19, the rotating arm 5 and the rotating shaft 8 cannot continue to rotate, and the first spring 11 cannot continue to be compressed. When the support beam 19 continues to move downward, the second spring 16 continues to be compressed, so that the support beam 19 falls onto the working surface of the roller 21 under the action of gravity, and does not fall onto the flange of the roller 21.

[0040] 4. After the die table 18 is removed, under the action of the first spring 11 and the second spring 16 , the roller 6 and the rotating arm 5 return to their original positions, waiting for the next die table 18 .

[0041] In order to increase the pulling force of the roller 6 on the support beam 19, the pitch of the thread used by the rotating shaft 8 and the support tube 2 can be increased, and multiple threads can be used at the same time.

[0042] During operation, the rollers 6 on the four guide devices can respectively move the two support beams 19 laterally, so that the support beams 19 are subjected to a more uniform force, are not easily skewed, and are more easily straightened. By increasing the distance between the two rollers 6 on each guide device, the die table 18 can be straightened even when the lateral deviation is larger (such as 20 mm or more). In addition, the first spring 11 and the second spring 16 can play a buffering role to prevent the support beam 19 from being too impacted when falling, which may shorten the life of the roller 21 or cause a malfunction.

[0043] The top surface of the sliding sleeve 3 is symmetrically provided with two coaxial arc-shaped limit grooves 10, and the bottom surface of the rotating arm 5 is fixedly connected with two limit pins 9 that can move in the corresponding limit grooves 10. The rotation range and starting position of the rotating arm 5 can be limited by the limit grooves 10 and the limit pins 9, so as to prevent the roller 6 and the support beam 19 from interfering with each other when the support beam 19 moves downward.

[0044] The lower part of the sliding sleeve 3 is sleeved outside the support tube 2, and vertical sliding holes 13 are provided on both sides of the lower part of the sliding sleeve 3. Each sliding hole 13 is provided with a sliding pin 15 that slides with the sliding sleeve 3, and the sliding pins 15 are fixedly connected to the support tube 2. Through the cooperation of the sliding pin 15 and the sliding hole 13, the sliding sleeve 3 can be vertically limited to prevent the sliding sleeve 3 from slipping off the support tube 2.

[0045] Example 2

[0046] Combination Fig. 9 As shown, the difference between this embodiment and embodiment 1 is that:

[0047] The second spring 16 is no longer provided, and the base 1 and the support tube 2 are fixedly connected.

[0048] The upper end of the rotating shaft 8 is rotatably connected to the rotating arm 5 through a one-way transmission member 17, and the one-way transmission member 17 is a one-way bearing or a ratchet. The lower part of the rotating shaft 8 is a driving head 14 with external threads. The upper center of the support tube 2 is a threaded hole. The lower part of the support tube 2 is a return hole 22 with a diameter larger than the outer diameter of the driving head 14. The return hole 22 is coaxial with the threaded hole. The diameter of the upper part of the rotating shaft 8 is smaller than the inner diameter of the threaded hole. A torsion spring 4 is provided between the rotating arm 5 and the sliding sleeve 3.

[0049] In this embodiment, after the support beam 19 is pressed on the support component 7, the rotating arm 5 and the rotating shaft 8 are driven downward by gravity, the first spring 11 is compressed, and the rotating shaft 8 is driven to rotate by the action of the thread between the driving head 14 and the support tube 2. The rotating shaft 8 drives the rotating arm 5 to rotate in the forward direction through the one-way transmission member 17, so that the two rollers 6 approach and push the support beam 19 in the horizontal direction. When the middle position of the support beam 19 is aligned with the support component 7, the driving head 14 is disengaged from the threaded part on the upper part of the support tube 2, the rotating arm 5 is reversed under the drive of the torsion spring 4, and the rotating arm 5 drives the rotating shaft 8 to rotate in the opposite direction through the one-way transmission member 17, so that the rollers 6 are away from the support beam 19. The support beam 19 continues to move downward, and the first spring 11 continues to be compressed, so that the support beam 19 falls downward to the working surface of the roller 21 below the die table 18. Afterwards, the support beam 19 moves along the roller 21, so that the support beam 19 is separated from the support component 7. Driven by the first spring 11, the drive head 14 re-enters the upper part of the support tube 2, and the rotating shaft 14 rotates in the opposite direction under the action of the thread. Since the rotating shaft 8 and the rotating arm 5 are connected by a one-way transmission member 17, the position of the rotating arm 5 is limited by the limit pin 9, so the rotating arm 5 will not rotate in the opposite direction with the rotating shaft 8.

[0050] When the rotating arm 5 drives the rotating shaft 8 to reverse, the limiting pin 9 abuts against the end of the limiting groove 10, and the rotating arm 5 returns to the initial position. At this time, the head of the thread on the driving head 14 is aligned with the head of the thread on the upper part of the support tube 2, so that the driving head 14 can accurately enter the thread on the upper part of the support tube 2 when it moves upward under the drive of the first spring 11. Of course, the thread can also adopt a multi-start thread, and the side wall of the groove of the thread is chamfered at the initial position of the thread to increase the width of the groove at the starting position of the thread, or the initial position thread protrusion of the driving head 14 is chamfered to reduce the thickness of the initial position thread protrusion of the driving head 14, so that the driving head 14 can more easily enter the thread on the upper part of the support tube 2.

[0051] In this embodiment, since the roller 6 will move away from the support beam 19 after straightening the support beam 19, when the support beam 19 moves along the roller 21, it will not be affected by the roller 6, so that the movement is smoother and the wear of the roller 6 can also be reduced.

[0052] Example 3

[0053] like Figure 8As shown, the difference between this embodiment and embodiment 1 is that:

[0054] The swinging directions of the rotating arms 5 on the two adjacent guide devices are opposite, so that after the support beam 19 is straightened, the rotating arms 5 of the two adjacent guide devices are in an eight-shaped shape, which can reduce the longitudinal combined force on the support beam 19, thereby avoiding the longitudinal movement of the support beam 19 due to the force.

[0055] The above-mentioned embodiments are described in a relatively detailed and specific manner, expressing the preferred embodiments of the present invention, and are only used to illustrate the technical ideas and features of the present invention. The purpose is to enable technicians in this field to understand the contents of the present invention and implement them accordingly, but are not limited to the present invention.
