Description

Technical Field

[0001] This application relates to the field of demolding technology for autoclaved aerated concrete products, specifically a mold tilting overhead crane device. Background Technology

[0002] It is a porous concrete product made primarily from fly ash, lime, cement, gypsum, and slag, through processes such as batching and mixing, pouring, static curing, cutting, and high-pressure steam curing. This product is lightweight, heat-insulating, sound-insulating, and fire-resistant, and is widely used in the construction industry.

[0003] In the preparation process of autoclaved aerated concrete (AAC) products, after the raw materials are mixed, poured into the mold, and initially cured, the mixture in the mold has formed into blocks, but it is not completely dry and still contains water. At this time, the blank in the mold needs to be poured out so that it can be cut according to the required size. Chinese patent (publication number: CN201792414U) discloses a lifting and turning device for AAC blocks and their molds, so that the mold can be lifted and turned over so that the material inside can be released and fall into the receiving hopper. However, when demolding in the above document, the material is easily smashed into the receiving hopper by the impact force generated when it falls, which can easily cause deformation and damage to the incompletely cured material. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a mold tilting overhead crane device, which has advantages such as being less prone to damage and solves the problem of easy damage.

[0005] To achieve the above objectives, this application provides the following technical solution: a mold tilting overhead crane device, including an overhead crane tilting mechanism and a receiving bin, wherein concave plates are abutted against the left and right walls of the inner side of the overhead crane tilting mechanism, a mold is fixed inside the concave plates, and a shielding structure is provided at the lower end of the mold;

[0006] The shielding structure includes two sliding plates, two connecting plates, two moving blocks fixedly installed on the top of the two sliding plates, a telescopic structure fixedly installed inside the two connecting plates, and a rotating structure fixedly installed inside the concave plate. A screw rod passes through the interior of the two moving blocks in the same group.

[0007] By adopting the above technical solution, the mold tilting overhead crane equipment, by setting up a shielding component, can prevent the semi-cured material from detaching from the mold when the mold is tilted, so that when the overhead crane mechanism moves it to the semi-cured material at the bottom or top of the receiving hopper, the mold can be demolded. This can effectively reduce the impact force generated by the material falling during demolding, which could cause the material to fall into the receiving hopper and damage it.

[0008] Furthermore, the lower end of each concave plate is provided with an elongated hole for the left and right sets of moving blocks to pass through and slide inside.

[0009] The above technical solution is adopted so that the left and right sets of moving blocks can penetrate through the interior of the concave plate, making it easy to connect the slide plate and thus drive the slide plate to move.

[0010] Furthermore, each of the two moving blocks has a threaded hole on one side facing the other for the screw to pass through, and the screw is threaded to the inside of the threaded hole.

[0011] Using the above technical solution, the screw is threadedly connected to the threaded hole of the moving block, enabling the screw to drive the moving block to move.

[0012] Furthermore, the rotating structure includes a dual-axis motor, two transmission structures, two rotating rods, a worm gear fixedly installed at the output end of the dual-axis motor, and a worm wheel fixedly installed on the outer surface of the two rotating rods.

[0013] The above technical solution is adopted so that two screws can be driven to rotate in the concave plate at the same time, so that when the two screws drive the two sets of moving blocks to move relative to or away from each other, the two sets of moving blocks can drive the two sliding plates to move relative to or away from each other.

[0014] Furthermore, the transmission structure includes a driven sprocket fixed to the outer surface of the screw, and a main sprocket fixed to the outer surface of the rotating rod. The driven sprocket and the outer surface of the main sprocket are meshed with a chain.

[0015] By adopting the above technical solution, the rotating rod can drive the screw on its corresponding side to rotate through the transmission structure, so that the screw can rotate inside the concave plate.

[0016] Furthermore, the worm is located directly above the worm wheel, and the ends of the two worms away from the dual-axis motor are respectively rotatably connected to the left and right walls of the concave plate cavity through bearings.

[0017] The above technical solution is adopted so that the worm can be precisely aligned with the worm wheel, so that the worm and the worm wheel can mesh and drive the rotating rod to rotate, so that the worm can rotate stably within the concave plate.

[0018] Furthermore, the telescopic structure includes three sleeve rods fixed to one wall opposite to the inner cavity of the two connecting plates. Anti-detachment blocks are fixed to the opposite ends of the front and rear sets of sleeve rods, and springs are sleeved on the outer surface of the sleeve rods.

[0019] By adopting the above technical solution, the skateboard can be moved into the interior of the connecting plate, so as to further reduce the space occupied.

[0020] Furthermore, each of the two opposing sides of the sliding plate is provided with a sliding groove for the sleeve rod to be located inside it.

[0021] Using the above technical solution, the sleeve rod can move in or out of the interior of the slide plate through the sliding slot hole, so that the slide plate can compress the spring sleeved on the surface of the sleeve rod.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This mold-turning overhead crane equipment, by being equipped with a shielding component, can prevent the semi-cured material from detaching from the mold when it is turned over. This allows the crane mechanism to move the semi-cured material to the bottom or top of the receiving hopper cavity before the mold is demolded. This effectively reduces the impact force generated by the material falling during demolding, preventing it from hitting the receiving hopper and causing damage to the material.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figures 1 to 5The mold tilting overhead crane device in this embodiment includes a tilting mechanism 1 and a receiving bin 2. The left and right walls of the inner side of the tilting mechanism 1 are abutted by concave plates 4. A mold 3 is fixed inside the concave plates 4. The lower end of the mold 3 is provided with a shielding structure.

[0032] Please see Figures 2 to 5 The shielding structure in this embodiment includes two sliding plates 41, two connecting plates 42, two moving blocks 43 fixedly installed on the top of the two sliding plates 41, a telescopic structure fixedly installed inside the two connecting plates 42, and a rotating structure fixedly installed inside the concave plate 4. A screw 44 passes through the two moving blocks 43 in the same group.

[0033] The lower end of the concave plate 4 is provided with a long hole for the left and right sets of moving blocks 43 to pass through and slide inside it, so that the left and right sets of moving blocks 43 can pass through the interior of the concave plate 4, making it easy to connect the slide plate 41, thereby driving the slide plate 41 to move.

[0034] Furthermore, each of the two moving blocks 43 has a threaded hole on one side facing each other for the screw 44 to pass through. The screw 44 is threaded to the inside of the threaded hole. The screw 44 can drive the moving block 43 to move by being threaded to the threaded hole of the moving block 43.

[0035] Furthermore, the screw 44 is a dual-axis screw, which enables it to drive the two moving blocks 43 on the same side to move relative to each other or in opposite directions. Both ends of the two screws 44 are rotatably connected to the front and rear walls of the inner cavity of the concave plate 4 through bearings, so that the screws 44 can stably drive the moving blocks 43 to move within the concave plate 4.

[0036] In addition, the two slide plates 41 and the two connecting plates 42 are usually telescopic cover plates, and the side of the cover plate that abuts against the mold 3 is coated with an anti-sticking agent to prevent semi-dry materials from sticking to the cover plate. The opposite sides of the two connecting plates 42 are fixed with friction pads to reduce wear when they come into contact with and move against the inner wall of the receiving bin 2.

[0037] Please see Figure 3 The rotating structure in this embodiment includes a dual-axis motor 48, two transmission structures 49, two rotating rods 45, a worm gear 47 fixedly installed at the output end of the dual-axis motor 48, and a worm wheel 46 fixedly installed on the outer surface of the two rotating rods 45.

[0038] Secondly, the transmission structure 49 includes a driven sprocket fixed to the outer surface of the screw 44, and the transmission structure 49 also includes a main sprocket fixed to the outer surface of the rotating rod 45. The outer surfaces of the driven sprocket and the main sprocket are meshed with a chain, so that the rotating rod 45 on the same side can drive the screw 44 on the corresponding side to rotate through the transmission structure 49.

[0039] Furthermore, both ends of the two rotating rods 45 are rotatably connected to the front and rear walls of the inner cavity of the concave plate 4 via bearings, so that the two rotating rods 45 can rotate stably within the concave plate 4, thereby enabling them to stably drive the screw 44 to rotate.

[0040] In addition, the worm 47 is located directly above the worm wheel 46 so that the worm 47 can be precisely aligned with the worm wheel 46, allowing the worm 47 and the worm wheel 46 to mesh and drive the rotating rod 45 to rotate. The ends of the two worms 47 away from the dual-axis motor 48 are respectively rotatably connected to the left and right walls of the inner cavity of the concave plate 4 through bearings, so that the worm 47 can be stably rotated within the concave plate 4.

[0041] Please see Figures 4 to 5 In this embodiment, the telescopic structure includes three sleeve rods 410 fixed to one wall opposite to the inner cavity of the two connecting plates 42. Anti-detachment blocks 412 are fixed to the opposite ends of the front and rear sets of sleeve rods 410, and springs 411 are sleeved on the outer surface of the sleeve rods 410.

[0042] Meanwhile, each of the two sliding plates 41 has a sliding groove on one of its opposite sides for the sleeve rod 410 to be located inside it. The sleeve rod 410 can move in or out of the interior of the sliding plate 41 through the sliding groove so that the sliding plate 41 can compress the spring 411 sleeved on the surface of the sleeve rod 410.

[0043] Furthermore, the anti-detachment block 412 is located inside the sliding groove hole, and the diameter of the anti-detachment block 412 is larger than the outlet diameter of the sliding groove hole, so that the sleeve rod 410 can be effectively prevented from detaching from the slide plate 41 through the anti-detachment block 412, thus ensuring that the slide plate 41 is not easy to fall off from the connecting plate 42.

[0044] Furthermore, both the front and rear connecting plates 42 are hollow rectangles, and the opposite side of both the front and rear connecting plates 42 is missing, so that the front and rear sliding plates 41 can move into the interior of the connecting plates 42.

[0045] It should be noted that the overhead crane tilting mechanism 1, the receiving bin 2, the mold 3, and the electronic components mentioned in the text are all commonly known in the prior art. Furthermore, the control method of this embodiment is controlled by a controller. All electrical components mentioned in the text are connected to the controller and the power supply. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The provision of the power supply is also common knowledge in the art. Therefore, this utility model will not explain the control method and circuit connection in detail.

[0046] The working principle of the above embodiments is as follows:

[0047] In operation, the overhead crane tilting mechanism 1 tilts the mold 3 so that its unloading end aligns with the top of the receiving bin 2. This causes the overhead crane tilting mechanism 1 to move the mold 3 downwards. The mold 3 then moves the cover plate, composed of two sliding plates 41 and two connecting plates 42, until it comes into contact with the bottom wall of the receiving bin 2. This causes the output of the dual-shaft motor 48 to drive the two worm gears 47 to rotate. The two worm gears 47 then mesh with the two worm wheels 46, allowing the worm gears 47 to rotate. Then the two worm gears 46 can drive the two rotating rods 45 to rotate, which in turn drives the two screws 44 to rotate through the two transmission structures 49. The two screws 44 can simultaneously drive the front and rear sets of moving blocks 43 to move in opposite directions. The front and rear sets of moving blocks 43 can then drive the front and rear slide plates 41 to move in opposite directions. The two slide plates 41 push the front and rear connecting plates 42 to move under the resistance of the telescopic structure. This allows the semi-formed material in the middle to contact the bottom wall of the inner cavity of the receiving bin 2 under the action of inertia.

[0048] At the same time, the two sets of moving blocks 43 drive the two sliding plates 41 to move continuously, causing the opposite side of the two connecting plates 42 to abut against the front and rear walls of the inner cavity of the receiving bin 2. The two sliding plates 41 move under the continuous drive of the two sets of moving blocks 43, so that the sliding plates 41 gradually move into the interior of the connecting plates 42. The sleeve rod 410 gradually moves into the sliding plate 41 and squeezes the spring 411, so that the telescopic cover plate no longer blocks the semi-formed material located on both sides of the mold 3. It also slides down due to inertia and abuts against the bottom wall of the inner cavity of the receiving bin 2. The overhead crane tilting mechanism 1 drives the mold 3 to move upward, so that the material can be completely removed from the mold 3. This can effectively reduce the impact force generated by the falling material during demolding, which may cause the material to be damaged when it hits the receiving bin 2.

[0049] When the overhead crane tilting mechanism 1 moves the mold 3 out of the receiving bin 2, the two connecting plates 42 no longer abut against the inner wall of the receiving bin 2, so that the two sets of springs 411 can push the two connecting plates 42 to move, so that the slide plate 41 moves out of the connecting plate 42, and the slide plate 41 and the connecting plate 42 unfold and reset.
