Description

Technical Field

[0001] This invention relates to the field of cement pole production equipment technology, and more specifically to a demolding device for cement pole production. Background Technology

[0002] After cement utility poles are centrifugally molded, the pole body needs to be removed from the steel mold. In actual production, many manufacturers use electrically controlled grippers to hold the mold or the pole body with the mold for lifting, moving and demolding. Due to the large weight and length of the mold plus the wet concrete, the force is concentrated at the gripping position. The clamping force of the electrically controlled gripper is easily affected by factors such as hydraulic fluctuations, aging of seals, and release agent or cement slurry adhering to the mold surface. There is a risk of sudden slippage or slow slippage. Once the mold falls off the gripper, it may damage the equipment or cause mold deformation, or even injure the on-site operators.

[0003] Currently, there are two common practices: one is to manually insert pins, tie chains, or install mechanical locking after grabbing, but this increases the number of manual operation steps, requiring workers to be close to the work, which reduces the production cycle and poses safety hazards; the other is to set up a bracket in a fixed position, but the bracket cannot move with the mold and can only provide support when placed in a fixed position, and cannot provide continuous protection during lifting and transportation.

[0004] Although some existing equipment is equipped with detection and alarm devices, most of them can only issue an alarm after detecting slippage, and cannot immediately provide physical support when the mold just begins to slip. When slipping slowly, personnel often do not have time to react.

[0005] Therefore, there is a need for an auxiliary device that can not affect the normal gripping efficiency of the electronically controlled gripper, but can quickly intervene, provide support and buffer when the mold shows signs of slipping, in order to reduce safety risks during demolding and handling. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a demolding device for cement pole production to solve the problems existing in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a demolding device for cement pole production, comprising an electrically controlled demolding device, wherein an electrically controlled displacement device is provided at the bottom of the electrically controlled demolding device, an electrically controlled lifting assembly is provided at the top of the electrically controlled demolding device, and an electrically controlled gripper assembly is installed at the lifting end of the electrically controlled lifting assembly; The moving end of the electrically controlled gripper assembly is equipped with a gripper plate, and the side of the gripper plate is provided with an electrical control component that can control the gripper plate to switch between an open state and a closed state; the outer sides of both ends of the gripper plate are provided with auxiliary anti-fall-off components, and the inner sides of both ends of the gripper plate are provided with buffer sensing components. During the process of the gripper plate clamping the cement pole mold, the auxiliary anti-drop component is in the unfolded state and moves to the bottom of the mold in the clamping state without contacting the bottom of the mold; the buffer sensing component is used to monitor whether the mold is in a slow slipping state. Furthermore, the buffer sensing component only controls the auxiliary anti-fall component to enter a locked state when it detects that the mold is in a slow falling state, so as to prevent the mold from continuing to slowly fall into the on-site processing environment.

[0008] Preferably, the outer sides of both ends of the gripper plate are provided with rotating grooves, and an auxiliary gripper is movably connected inside the rotating groove. A movable rod is installed through the auxiliary gripper near the rotating groove. One end of the movable rod is equipped with a torsion spring assembly. The torsion spring force of the torsion spring assembly drives the auxiliary gripper to move to the bottom of the mold through the movable rod, without contacting the bottom of the mold.

[0009] Preferably, a fixed wheel is installed in the middle area of ​​the other end of the movable rod, the fixed wheel is movably sleeved inside the rotating groove, and a retaining plate is installed at the end of the other end of the movable rod, the retaining plate having a limit groove inside.

[0010] Preferably, an electro-hydraulic column is installed inside the rotating groove near the limiting groove, and a locking block is installed at the lifting end of the electro-hydraulic column, the outer side of the locking block being adapted to the inner side of the limiting groove.

[0011] Preferably, a rope is installed in the middle area of ​​the upper surface of the auxiliary gripper, and an auxiliary push plate is installed at the end of the rope away from the auxiliary gripper. A transmission column is slidably sleeved on the outside of the auxiliary push plate. A first spring is installed between the bottom surface of the auxiliary push plate and the inner side of the bottom of the transmission column. The upper surface of the auxiliary push plate and the inner wall of the transmission column together form a hydraulic cavity. A fixed amount of hydraulic oil is stored in the hydraulic cavity. A pulley block is provided in the middle area of ​​the rope, and a delivery pipe is installed inside the hydraulic cavity.

[0012] Preferably, the inner side of the middle area of ​​the two sets of gripper plates is provided with a sliding groove, and a buffer plate is slidably sleeved inside the sliding groove.

[0013] Preferably, a hollow plate is installed in the middle area of ​​the buffer plate near the chute, a support rod is installed in the middle area of ​​the hollow plate, and a hydraulic plate is installed at the end of the support rod away from the hollow plate.

[0014] Preferably, a hydraulic storage plate is slidably sleeved on the outside of the hydraulic plate, a third spring is installed between the middle area of ​​the side of the hydraulic plate away from the position of the second spring and the opposite surface of the hydraulic storage plate, a fourth spring is also installed between the two ends of the side of the hydraulic plate away from the position of the second spring and the opposite surface of the hydraulic storage plate, and an inductive switch is installed on the inner side of the hydraulic storage plate near the position of the fourth spring.

[0015] The technical effects and advantages of this invention are as follows: This invention uses an auxiliary anti-drop component that extends to the bottom of the mold during clamping without contacting the mold, thus not affecting the normal clamping and handling rhythm of the electronically controlled gripper, avoiding additional manual locking steps, and maintaining the original demolding efficiency.

[0016] This invention distinguishes between two states: slow slippage and rapid detachment of the mold using a buffer sensing component. Only when the mold is judged to be slipping slowly will the auxiliary anti-detachment component be controlled to enter the locking state, thereby achieving targeted protection and avoiding interference with normal processes.

[0017] This invention uses a hydraulic plate that tilts up at one end so that only one of the two sets of inductive switches is continuously triggered when the mold slides slowly. By using a trigger time threshold to determine the type of slippage, it can detect slow slippage in time and lock it in advance to prevent the mold from continuing to slide down to the ground.

[0018] This invention uses a hydraulic chamber, an auxiliary push plate, and a first spring to form a damping structure. Even if there is no time to lock the mold when it falls rapidly, the auxiliary push plate can be driven by a rope to generate hydraulic damping and compress the spring, thus buffering the mold that falls suddenly and reducing the impact damage to personnel and equipment on site.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The demolding device for cement pole production involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figures 1 to 7 As shown, the present invention provides a demolding device for cement pole production, including an electrically controlled demolding device 1, an electrically controlled displacement device 2 at the bottom of the electrically controlled demolding device 1, an electrically controlled lifting assembly 3 at the top of the electrically controlled demolding device 1, and an electrically controlled gripper assembly 4 installed at the lifting end of the electrically controlled lifting assembly 3. The moving end of the electric gripper assembly 4 is equipped with a gripper plate 402. The side of the gripper plate 402 is provided with an electric control component 401, which can control the gripper plate 402 to switch between an open state and a closed state. The outer sides of both ends of the gripper plate 402 are provided with auxiliary anti-drop components 5, and the inner sides of both ends of the gripper plate 402 are provided with buffer sensing components 6. During the process of gripping the cement pole mold by the gripper plate 402, the auxiliary anti-drop component 5 is in the unfolded state and moves to the bottom of the mold in the gripping state without contacting the bottom of the mold; the buffer sensing component 6 is used to monitor whether the mold is in a slow slipping state. Furthermore, only when the buffer sensing component 6 detects that the mold is in a slow sliding state, the buffer sensing component 6 controls the auxiliary anti-drop component 5 to enter the locking state to prevent the mold from continuing to slowly slide into the on-site processing environment.

[0023] In this embodiment of the application, the electrically controlled demolding device 1 serves as the main body of the machine, and an electrically controlled displacement device 2 is installed at the bottom. The electrically controlled displacement device 2 is usually a track-walking trolley or a wheeled mobile platform, which can drive the entire device to move along the production line direction to the demolding station. The top of the electrically controlled demolding device 1 is equipped with an electrically controlled lifting assembly 3. The lifting end of the electrically controlled lifting assembly 3 is connected to the electrically controlled gripper assembly 4, which is used to drive the electrically controlled gripper assembly 4 to rise and fall in the vertical direction to align with the mold at different height positions.

[0024] The moving end of the electrically controlled gripper assembly 4 is equipped with a gripper plate 402, and the electrically controlled assembly 401 is a conventional driving component such as a hydraulic cylinder, air cylinder or electric push rod that drives the gripper plate 402 to move. When gripping the mold, the electronic control component 401 first drives the gripper plates 402 on both sides to open outward, so that the opening between the two gripper plates 402 is larger than the diameter of the mold. The electrically controlled displacement device 2 drives the entire unit to move above the mold, and the electrically controlled lifting assembly 3 descends, so that the gripper plate 402 is located on both sides of the mold; Subsequently, the electrical control component 401 drives the gripper plate 402 to close inward, clamping the outer wall of the mold; the electrical control lifting component 3 rises, which can lift the mold or demold it for transport.

[0025] The structures and gripping actions of the above-mentioned electrically controlled demolding device 1, electrically controlled displacement device 2, electrically controlled lifting assembly 3, electrically controlled gripper assembly 4, and the electrically controlled assembly 401 and gripper plate 402 are all existing technologies, and their specific structures will not be elaborated in detail in this embodiment.

[0026] Reference Figures 1 to 7 As shown, the present invention provides a demolding device for cement pole production. Rotating grooves 403 are provided inside the outer sides of both ends of the gripper plate 402. An auxiliary gripper 501 is movably connected inside the rotating groove 403. A movable rod is installed through the auxiliary gripper 501 near the rotating groove 403. A torsion spring assembly 509 is installed at one end of the movable rod. The torsion spring force of the torsion spring assembly 509 drives the auxiliary gripper 501 to move to the bottom of the mold through the movable rod, without contacting the bottom of the mold. A fixed wheel 510 is installed in the middle area of ​​the other end of the movable rod. The fixed wheel 510 is movably sleeved inside the rotating groove 403. A slot plate 512 is installed at the end of the other end of the movable rod. A limit groove is opened inside the slot plate 512. An electro-hydraulic column 513 is installed inside the rotating groove 403 near the limit groove. A locking block 511 is installed at the lifting end of the electro-hydraulic column 513. The outer side of the locking block 511 is adapted to the inner side of the limit groove.

[0027] In this embodiment of the application, the torsion spring force generated by the torsion spring assembly 509 drives the auxiliary gripper 501 to move to the bottom of the mold. When the mold is in the normal clamping state, the auxiliary gripper 501 is not in contact with the mold. When the auxiliary gripper 501 is not in contact with the bottom of the mold, the limiting groove of the slot plate 512 and the locking block 511 are in a relatively accurate position. When the buffer sensing component 6 determines that the mold is slowly slipping during the clamping process of the gripper plate 402, the electro-hydraulic column 513 is activated and controls the locking block 511 to move into the inside of the limiting groove to fix the locking plate 512. At this time, the auxiliary anti-drop component 5 enters the locking state to prevent the mold from continuing to slowly slip into the on-site processing environment.

[0028] A rope 502 is installed in the middle area of ​​the upper surface of the auxiliary gripper 501. An auxiliary push plate 506 is installed at the end of the rope 502 away from the auxiliary gripper 501. A transmission column 504 is slidably sleeved on the outside of the auxiliary push plate 506. A first spring 507 is installed between the bottom surface of the auxiliary push plate 506 and the inner side of the bottom of the transmission column 504. The upper surface of the auxiliary push plate 506 and the inner wall of the transmission column 504 together form a hydraulic cavity 505. A certain amount of hydraulic oil is stored in the hydraulic cavity 505. A pulley block 503 is provided in the middle area of ​​the rope 502. A delivery pipe 508 is installed inside the hydraulic cavity 505.

[0029] In this embodiment, the external hydraulic source of the buffer sensing component 6 delivers hydraulic oil to the hydraulic chamber 505 through the delivery pipe 508, so that the hydraulic pressure in the hydraulic chamber 505 gradually increases, pushing the auxiliary push plate 506 to slide downward. During this process, the auxiliary push plate 506 overcomes the spring force generated by the first spring 507, and the rope 502 gradually loosens and is released outward from the transmission column 504, thereby relieving the pulling effect on the auxiliary gripper 501. At this time, the torsion spring force of the torsion spring assembly 509 drives the auxiliary gripper 501 to rotate around the fixed wheel 510 until the auxiliary gripper 501 moves to the bottom of the mold and does not contact the bottom of the mold, thus completing the deployment action of the auxiliary anti-drop assembly 5.

[0030] The auxiliary gripper 501 is initially located outside the gripper plate 402. Driven by the torsion spring assembly 509, the auxiliary gripper 501 rotates outward around the fixed wheel 510 and stops below the bottom edge of the mold after passing over it. Throughout the rotation, the auxiliary gripper 501 remains outside the outer contour of the mold and does not contact the outer wall of the mold.

[0031] The inner side of the middle area of ​​the two sets of gripper plates 402 is provided with a sliding groove. A buffer plate 601 is slidably sleeved inside the sliding groove. A hollow plate 602 is installed in the middle area of ​​the buffer plate 601 near the sliding groove. A support rod 606 is installed in the middle area of ​​the hollow plate 602. A hydraulic plate 607 is installed at the end of the support rod 606 away from the hollow plate 602. A hydraulic storage plate 608 is slidably sleeved outside the hydraulic plate 607. A third spring 605 is installed between the middle area of ​​the side of the hydraulic plate 607 away from the second spring 603 and the opposite surface of the hydraulic storage plate 608. A fourth spring is also installed between the two ends of the side of the hydraulic plate 607 away from the second spring 603 and the opposite surface of the hydraulic storage plate 608. An inductive switch 604 is installed on the inner side of the hydraulic storage plate 608 near the fourth spring.

[0032] In this embodiment, the end of the delivery pipe 508 away from the hydraulic chamber 505 passes through the interior of the hydraulic storage plate 608, and this end port is close to the location of the third spring 605.

[0033] Two sets of induction switches 604 are installed on the inner sides of both ends of the hydraulic storage plate 608. When the gripper plate 402 clamps the mold, the buffer plate 601 first contacts the outside of the mold. The mold pushes the buffer plate 601, causing the buffer plate 601 to drive the hydraulic plate 607 to move into the hydraulic storage plate 608 through the support rod 606. The hydraulic oil inside the hydraulic storage plate 608 flows into the hydraulic chamber 505 through the delivery pipe 508 under the pressure of the hydraulic plate 607.

[0034] During the process of gripper plate 402 clamping the mold, hydraulic plate 607 moves to contact the two sets of inductive switches 604, the two sets of inductive switches 604 are triggered and send a signal to the control center inside the electric demolding device 1. When the mold slowly detaches, the supporting force of the buffer plate 601 on the mold gradually decreases, and the hydraulic plate 607 gradually retracts under the action of hydraulic oil and spring. Since the hydraulic plate 607 has a rubber layer on the outside, one end of the hydraulic plate 607 is tilted up under the action of the fourth spring, so that only one end of the hydraulic plate 607 keeps in contact with the corresponding inductive switch 604, while the other end of the inductive switch 604 is out of contact and is not triggered. The two sets of inductive switches 604 change from being triggered simultaneously to being triggered by only one set. If the triggering time of the two sets of inductive switches 604 exceeds 3 seconds, the control center judges that the mold is in a slow detachment state. When the mold falls off rapidly, the hydraulic plate 607 retracts quickly within a short time, and the two sets of induction switches 604 are triggered simultaneously within 1-3 seconds. The control center determines that the mold is in a state of rapid falling off. At this time, the control center does not control the auxiliary anti-fall component 5 to enter the locked state, and at the same time sends a warning signal to the outside world.

[0035] The specific workflow for this application is as follows: Step 1: The electric displacement device 2 moves the entire device along the production line to the position above the demolding station, and the electric lifting component 3 descends, so that the gripper plate 402 of the electric gripper component 4 is located on both sides of the mold. Subsequently, the electronic control component 401 drives the gripper plate 402 to close inward, clamping the outer wall of the mold. While the clamping action is in progress, the external hydraulic source delivers hydraulic oil to the hydraulic chamber 505 through the delivery pipe 508, pushing the auxiliary push plate 506 to slide downward and overcome the spring force of the first spring 507. As a result, the rope 502 gradually loosens and is released outward from the transmission column 504, releasing the pull on the auxiliary gripper 501. At this time, the torsion spring force of the torsion spring assembly 509 drives the auxiliary gripper 501 to rotate around the fixed wheel 510 until the auxiliary gripper 501 moves to below the bottom of the mold and does not contact the bottom of the mold, thus completing the deployment action of the auxiliary anti-drop assembly 5 and providing a safety net for the mold to slip in the future.

[0036] Step 2: After the mold is clamped, the electrically controlled lifting component 3 rises to lift the mold or to demold and transport it. During this process, the buffer plate 601 in the buffer sensing assembly 6 remains in contact with the outer wall of the mold. The mold pushes the buffer plate 601, causing the buffer plate 601 to move the hydraulic plate 607 into the hydraulic storage plate 608 via the support rod 606. The hydraulic oil in the hydraulic storage plate 608 flows into the hydraulic chamber 505 through the delivery pipe 508 under the pressure of the hydraulic plate 607. As the hydraulic plate 607 moves, its two ends contact the two sets of inductive switches 604 installed on the inner sides of the two ends of the hydraulic storage plate 608. Both sets of inductive switches 604 are triggered and send a signal to the control center inside the electronically controlled demolding device 1, indicating that the mold is in a normal clamping state. At this time, the auxiliary gripper 501 is still located below the bottom of the mold but does not contact the mold and does not interfere with the normal process.

[0037] Step 3: When the mold slowly falls off, the supporting force of the buffer plate 601 on the mold gradually decreases, and the hydraulic plate 607 gradually retracts under the action of hydraulic oil and spring. Because the hydraulic plate 607 has a rubber layer on the outside and one end of it is raised under the action of the fourth spring, only one end of the hydraulic plate 607 is in contact with the corresponding inductive switch 604, while the other end of the inductive switch 604 is out of contact and not triggered. The two sets of inductive switches 604 are changed from being triggered simultaneously to being triggered by only one set. If the triggering time of the induction switch 604 exceeds 3 seconds, the control center determines that the mold is in a slow sliding state, and then starts the electro-hydraulic column 513 to drive the block 511 to extend into the limiting groove of the slot plate 512, fixing the position of the movable rod and the auxiliary gripper 501, so that the auxiliary anti-drop component 5 enters the locked state, thereby preventing the mold from continuing to slide down. When the mold falls rapidly, the hydraulic plate 607 retracts quickly within a short time, and the two sets of inductive switches 604 are triggered simultaneously within 1-3 seconds. The control center determines that the mold is in a state of rapid fall. At this time, the control center does not control the auxiliary anti-fall component 5 to enter the locked state, but instead sends a warning signal to the outside world to remind the on-site personnel to pay attention. At the same time, when the mold suddenly falls, the auxiliary gripper 501 can drive the auxiliary push plate 506 to move in the hydraulic chamber 505 through the rope 502. With the help of hydraulic damping and the compression of the first spring 507, a certain buffering effect is achieved, reducing the damage caused by the sudden fall of the mold to the site.
