DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0034] Embodiment one: please refer to Figures 1-3 、 Figure 6 、 Figure 7 、 Figure 8 The present application is a sand core transfer device, which comprises a vehicle body 1, a support plate 4 installed on the top of the vehicle body 1, and a supporting structure 2 arranged on both sides of the support plate 4 for supporting a sand core body 5. When transferring the sand core, the vehicle is used to assist the transfer of large pieces of the sand core, and the placement posture of the sand core is ensured during the transfer process by the supporting structure 2.

[0035] The supporting structure 2 comprises a swing plate 28, the top side of the vehicle body 1 is fixed with a support frame 21 in a vertical state, the swing plate 28 is rotatably installed between the two support frames 21 through pin shaft cooperation, the swing plate 28 can have a certain swing angle, and the supporting direction of the supporting plate 31 can be better corresponded to the outer side of the transported sand core body 5. The side surface of the swing plate 28 is equipped with an electric cylinder 30, the acting rod end of the electric cylinder 30 penetrates the swing plate 28, and the acting end of the electric cylinder 30 is fixed with the supporting plate 31. The supporting plate 31 is used for supporting the sand core body 5, and under the action of the electric cylinder 30, the supporting plate 31 can be pushed close to the sand core body 5 to realize auxiliary support;

[0036] The bottom side of the supporting plate 31 is fixedly attached with a supporting air bag 32. The supporting air bag 32 is directly contacted with the outer side wall of the sand core body 5. By using the softness and variability of the supporting air bag 32, the supporting air bag 32 can better contact the outer side of the irregular sand core body 5, and more contact supporting points can be generated without directly causing collision damage to the sand core body 5.

[0037] Please refer to Figure 6 、 Figure 8 , wherein the top side of the supporting plate 31 is fixed with a pressure limiting structure 33. The pressure limiting structure 33 comprises a closed cylinder 338. A communication hole 332 is formed in the bottom of the closed cylinder 338. The communication hole 332 is in communication with the supporting air bag 32 through an air pipe. By arranging the air pipe, the communication between the supporting air bag 32 and the closed cylinder 338 can be realized. After the supporting air bag 32 is contacted with the sand core body 5, the supporting air bag 32 is deformed by being extruded when the supporting plate 31 is pushed, so that the sand core body 5 is in a wrapping supporting state, and damage to the sand core body 5 is avoided. At the same time, because the supporting air bag 32 has more stress points or stress surfaces on the outer side of the sand core body 5, the sand core body 5 is more stable under the condition of multi-point stress.

[0038] A rod hole is formed in the top of the closed cylinder 338. An movable rod 331 is slidably installed in the rod hole. The bottom end of the movable rod 331 is fixed with a piston 333. The outer side wall of the piston 333 is tightly slid with the inner side wall of the closed cylinder 338. The closed cylinder 338 is located between the bottom space of the piston 333 and the supporting air bag 32 to form an overall space, so that the inherent gas in the supporting air bag 32 is prevented from overflowing. A compression spring 334 is arranged on the periphery of the movable rod 331. The top of the compression spring 334 is fixed to the top inner wall of the closed cylinder 338. The bottom end of the compression spring 334 is fixed to the top side of the piston 333.

[0039] After the supporting air bag 32 is in contact with the sand core body 5 and is extruded, the gas in the supporting air bag 32 is introduced into the closed cylinder 338, the volume of the gas in the cavity at the bottom of the piston 333 is increased, the piston 333 is pushed upward, the compression spring 334 is compressed, and the compression spring 334 generates a restoring force to provide a thrust force for the return of the piston 333.

[0040] The top of the closed cylinder 338 is fixed with a guide cylinder 335, the inner wall of the guide cylinder 335 is provided with an electrode ring 336, the top end of the movable rod 331 is fixed with an electrode cap 337, the circumferential surface of the electrode cap 337 is in sliding contact with the inner side surface of the electrode ring 336, the swing plate 28 is provided with an indicating lamp 39, and the electrode cap 337, the electrode ring 336 and the indicating lamp 39 are connected with a storage battery to form a circuit.

[0041] After the supporting air bag 32 is in contact with the sand core body 5 and is extruded, the degree of wrapping of the supporting air bag 32 is determined by the deformation amount, and the amount of gas extruded by the supporting air bag 32 is ensured to be the same for different sand core bodies 5 and different deformation positions, so that the supporting of different sand core bodies 5 is limited.

[0042] The swing plate 28 is provided with two positioning holes, and the two positioning holes are located on the two sides of the electric cylinder 30, the top side of the supporting plate 31 is fixed with two limiting rods 29, and the limiting rods 29 are slidingly arranged in the positioning holes, so that the swing plate 28 and the supporting plate 31 are parallel to each other, and the angle of the swing plate 28 is adjusted, and the angle of the supporting plate 31 is adjusted.

[0043] In use, the angle of the swing plate 28 is adjusted to adjust the angle of the supporting plate 31, and under the action of the electric cylinder 30, the supporting plate 31 is pushed to be close to the sand core body 5 to assist in supporting.

[0044] With the advancement of the supporting plate 31, the supporting air bag 32, which is in direct contact with the outer side wall of the sand core body 5, utilizes the softness and variability of the supporting air bag 32 to better contact the irregular outer side surface of the sand core body 5, and more contact supporting points can be generated.

[0045] After the supporting air bag 32 is in contact with the sand core body 5, the supporting air bag 32 is extruded and deformed by pushing the supporting plate 31, so that the sand core body 5 is in a wrapping supporting state, and damage to the sand core body 5 is avoided, and the sand core body 5 is more stable under the condition of multi-point force because the supporting air bag 32 has more stress points or stress surfaces on the outer side of the sand core body 5.

[0046] After the supporting air bag 32 is in contact with the sand core body 5 and is extruded, the degree of wrapping of the supporting air bag 32 is determined by the deformation amount, and for different sand core bodies 5, the deformation position is different, but the amount of gas extruded by the extrusion is ensured to be constant, and the supporting of different sand core bodies 5 is also ensured to be limited,

[0047] After the supporting air bag 32 is in contact with the sand core body 5 and is extruded, the gas in the supporting air bag 32 is introduced into the closed cylinder 338, the volume of the gas in the cavity at the bottom of the piston 333 increases, and the piston 333 is pushed upward to realize the compression of the extrusion spring 334.

[0048] During the upward movement of the piston 333, the electrode cap 337 at the end of the movable rod 331 gradually approaches the electrode ring 336, and when the deformation amount of the supporting air bag 32 reaches the set value, the electrode cap 337 at this time should be in contact with the electrode ring 336 to realize the electrification of the indicator light 39. Otherwise, through the electrification state of the indicator light 39, the extrusion contact state of the supporting air bag 32 and the sand core body 5 can be ensured, the force of the supporting air bag 32 on the sand core body 5 can be ensured not to cause damage to the sand core body 5, and the supporting force of the supporting air bag 32 on the sand core body 5 can be ensured to be effective, so that better supporting effect can be ensured, and the integrity of the sand core body 5 can be ensured, and the damage to the sand core body 5 during transportation can be reduced.

[0049] At the same time, the electrode ring 336 is arranged as a ring structure through which the electrode cap 337 can pass, so that the piston 333 has a movement space when swinging, and under the restoring force of the extrusion spring 334, a buffer interval is left for the swinging during transportation, so that the sand core body 5 can be better protected from direct force impact during transportation.

[0050] In addition, the surface of the supporting air bag 32 is relatively smooth when used as a supporting structure, and the surface of the smooth supporting air bag 32 is easy to clean without clamping operation, and the surface of the supporting air bag 32 is affected by the residual supporting material, which affects the subsequent supporting operation.

[0051] Example two: please refer to Figure 5 , Figure 6As shown, the supporting structure 2 also includes a telescopic column 24, the interior of the telescopic column 24 is provided with a lifting spring 35 along the central axis, and a lifting rod 34 is vertically inserted into the central hole of the telescopic column 24, and the top of the lifting spring 35 is fixed to the bottom end face of the lifting rod 34, and a vertical limiting hole 38 is opened on the top circumferential wall of the telescopic column 24, and a sliding screw 37 perpendicular to the lifting rod 34 is fixed to the bottom of the lifting rod 34, and the sliding screw 37 is slidably arranged in the limiting hole 38, and the lifting spring 35 of the limiting hole 38 is set with a certain pre-tightening force, which can push the sliding screw 37 to the highest point of the limiting hole 38 during the natural extension of the lifting spring 35, and the sliding screw 37 is rotatably assembled with a locking nut 36, which is located on the outer wall of the telescopic column 24. The positioning of the sliding screw 37 can be achieved by rotating and squeezing the locking nut 36.

[0052] See also Figure 6 As shown, a sliding hole 23 is opened on the support frame 21, and the sliding rod 22 is arranged horizontally, and the two ends of the sliding rod 22 are respectively slidably set in the two sliding holes 23. A connecting seat 27 is fixed to the bottom side of the swing plate 28. A connecting member 26 is rotatably mounted on the connecting seat 27 through a pin shaft. The top of the lifting rod 34 is cross-connected with the middle part of the sliding rod 22. A connecting sleeve 25 is sleeved on the outside of the sliding rod 22, and the other end of the connecting member 26 is fixed to the outer surface of the connecting sleeve 25.

[0053] When in use, in order to adjust the supporting angle of the sand core body 5, the locking nut 36 is released by rotating, and the lifting rod 34 is pushed upward with the cooperation of the pre-tightening rebound force of the limit hole 38, so that the sliding rod 22 can slide in the sliding hole 23. When the sliding rod 22 moves upward, the locking nut 36 can be used to adjust the angle between the swing plate 28 and the support frame 21, thereby changing the angle of the swing plate 28 to adjust the angle of the supporting plate 31. After the angle is adjusted, the locking nut 36 is rotated, and the lifting rod 34 is inside the telescopic column 24, and the locking nut 36 is outside the telescopic column 24. The lifting rod 34 can be suspended with the cooperation of rotation and extrusion to adjust the supporting angle. Since the sand core body 5 to be used is the same structure, it basically does not require reciprocating high-frequency adjustment after application adjustment.

[0054] Example 3: Please refer to Figures 1-4 As shown, jacking cylinders 3 are vertically installed at the four corners of the bottom side of the vehicle body 1, and the top ends of the action rods of the four jacking cylinders 3 are used to support and connect the four corners of the same support plate 4; the height of the support plate 4 can be uniformly adjusted through the coordinated operation of the four jacking cylinders 3, so as to better adapt to the transportation operation of the sand core body 5;

[0055] The inside of the support plate 4 is internally provided with a turnover structure 7, the turnover structure 7 comprises a turnover plate 71, the inside of the support plate 4 is internally provided with a turnover groove 79, the turnover plate 71 is rotatably installed in the turnover groove 79 through a damping shaft 76, both ends of the vehicle body 1 are provided with assembly grooves, and the ends of the damping shaft 76 are installed through the assembly grooves, one end of the damping shaft 76 is externally provided with a turbine 75, and the turbine 75 is located in the assembly groove.

[0056] Please refer to Figure 7 As shown, the bottom side of the support plate 4 is provided with a mounting bracket 77, the mounting bracket 77 is located below the assembly groove, the bottom side of the mounting bracket 77 is provided with a turnover motor 78, the output shaft of the turnover motor 78 penetrates the mounting bracket 77, the output shaft of the mounting bracket 77 is fixedly connected with a worm 710, the turbine 75 and the worm 710 are cooperatively engaged and driven;

[0057] When it supports the sand core body 5, the surface of the turnover plate 71 is provided with a support backing plate 74 matched with the sand core body 5, which can provide a more matched support structure for hoisting and placing the sand core body 5;

[0058] Since the structure is applied to the bearing of different sand core bodies 5, based on the supporting device of the case, in order to realize stable supporting operation, when the relatively flat surface of the sand core is used as the stress surface of the support, when it is necessary to adjust the relatively flat surface of the sand core body 5 corresponding to the surface of the supporting air bag 32, it is necessary to control the turnover motor 78 to work, drive the worm 710 to work, and drive the turbine 75 to rotate, so as to realize the turnover of the turnover plate 71 under the cooperation of the damping shaft 76, realize intermittent adjustment in the turnover process, realize the determination of the turnover angle of the turnover plate 71 through slow calibration, and ensure the supporting effect of the supporting air bag 32 on the sand core body 5 and the stable effect of the transfer;

[0059] And since the sand core body 5 originally belongs to a fragile structure, it is easy to have debris and residues left in the support backing plate 74 during the transfer process, when cleaning is needed, the turnover groove 79 can be completely turned over to realize the complete pouring out of the remaining waste, and the waste on the smooth surface of the vehicle body 1 can be collected and treated, thereby improving the cleaning efficiency.

[0060] Please refer to Figure 4 As shown, the top side of the turnover plate 71 is provided with a mounting screw hole, the top side of the turnover plate 71 is cooperatively provided with a support backing plate 74, both ends of the support backing plate 74 are respectively fixedly provided with a connecting lug 73, the mounting hole of the connecting lug 73 corresponds to the mounting screw hole, the bottom end of the mounting screw rod 72 is rotatably installed in the mounting screw hole, and the end cap of the mounting screw rod 72 is pressed against the connecting lug 73, so that the support backing plate 74 is set to be a replaceable structure, which can be used when transferring the sand core body 5 in multiple forms, and can also be used when transferring the sand core body 5 in a regular form.

[0061] The controller 6 is installed on the vehicle body 1 and is used to support the structure 2, the electric cylinder 30 and the rotation control of the turnover motor 78, and the controller 6 is provided with a control program for simultaneously operating the four support frames 21, realizing power supply and control operation of the electric equipment in the whole transfer, and the deflection angle of the turnover plate 71 has a corresponding setting interval.

[0062] Working principle: in order to realize the transfer of the sand core body 5, the sand core body 5 after molding is placed on the support plate 74, and the support plate 74 matched with the sand core body 5 is assembled on the surface of the turnover plate 71, which can provide a relatively matched support structure for the hoisting and placing of the sand core body 5;

[0063] Because the structure is applied to the bearing of different sand core bodies 5, based on the supporting device of the case, in order to realize stable supporting operation, when the relatively flat surface of the sand core is used as the stress surface of the support, when it is necessary to adjust the relatively flat surface of the sand core body 5 corresponding to the surface of the supporting air bag 32, it is necessary to control the turnover motor 78 to work, drive the worm 710 to work, drive the turbine 75 to rotate, and realize the turnover of the turnover plate 71 under the cooperation of the damping shaft 76, realize the intermittent adjustment in the turnover process, realize the determination of the turnover angle of the turnover plate 71 through slow calibration, so as to ensure the supporting effect of the supporting air bag 32 on the sand core body 5 and ensure the stability of the transfer;

[0064] And because the sand core body 5 originally belongs to a fragile structure, it is easy to have residual slag and residues in the support plate 74 during the transfer process, and when cleaning is needed, the complete turnover of the turnover groove 79 can be realized to completely pour out the residual slag, and the slag on the smooth surface of the vehicle body 1 can be collected and treated, improving the cleaning efficiency.

[0065] In use, in order to realize the adjustment of the supporting angle of the sand core body 5, the release locking nut 36 is rotated, the lifting rod 34 is pushed upward under the cooperation of the pre-tightening elastic force of the limiting hole 38, the sliding rod 22 slides in the sliding hole 23, and the angle between the swing plate 28 and the support frame 21 can be adjusted through the cooperation of the locking nut 36 when the sliding rod 22 moves upward, so as to change the angle of the swing plate 28 and realize the adjustment of the angle of the supporting plate 31. After adjusting the angle, the lifting rod 34 is suspended by rotating and extruding the locking nut 36 inside the telescopic column 24 and the locking nut 36 outside the telescopic column 24, so as to realize the adjustment of the supporting angle. Because the sand core body 5 is of a structure, it basically does not need to be adjusted frequently after adjustment;

[0066] In use, by adjusting the angle of the swing plate 28, the angle of the supporting plate 31 is adjusted, and under the action of the electric cylinder 30, the supporting plate 31 can be pushed close to the sand core body 5 to achieve auxiliary support;

[0067] With the advancement of the supporting plate 31, the supporting air bag 32, as a supporting air bag 32 in direct contact with the outer side wall of the sand core body 5, utilizes the softness and variability of the supporting air bag 32, and can better contact the irregular outer side of the sand core body 5, and can generate more contact support points,

[0068] After the supporting air bag 32 contacts the sand core body 5, the supporting air bag 32 is extruded and deformed by pushing the supporting plate 31, which can generate a wrapping support state for the sand core body 5, which can avoid damage to the sand core body 5, and at the same time, due to the fact that the supporting air bag 32 has more stress points or stress surfaces on the outer side of the sand core body 5, the sand core body 5 is more stable under the condition of multi-point stress;

[0069] After the supporting air bag 32 is extruded and deformed by the sand core body 5, the degree of wrapping is determined by the deformation amount, and for different sand core bodies 5, the deformation position is different, but the amount of gas extruded by extrusion is always guaranteed, which can also guarantee the support limit for different sand core bodies 5,

[0070] After the supporting air bag 32 is extruded and deformed by the sand core body 5, the gas in the supporting air bag 32 will be introduced into the closed cylinder 338, and the gas volume in the cavity at the bottom of the piston 333 will increase, which can push the piston 333 upwards to realize the compression of the extrusion spring 334;

[0071] During the upward movement of the piston 333, the electrode cap 337 at the end of the movable rod 331 gradually approaches the electrode ring 336, and when the deformation amount of the supporting air bag 32 reaches a set value, the electrode cap 337 at this time should be in contact with the electrode ring 336 to realize the electrification of the indicator light 39. Otherwise, through the electrification state of the indicator light 39, the extrusion contact state of the supporting air bag 32 and the sand core body 5 can be ensured, which can prevent the supporting force of the supporting air bag 32 on the sand core body 5 from damaging the sand core body 5, and can also ensure that the supporting force of the supporting air bag 32 on the sand core body 5 is effective, which can ensure better supporting effect and ensure the integrity of the sand core body 5, reducing the damage to the sand core body 5 caused by transportation;

[0072] Meanwhile, the electrode ring 336 is arranged as a ring structure through which the electrode cap 337 can pass, so that the piston 333 has a space for movement when swinging occurs, and the piston 333 can have a buffer interval for the swing remaining in the transport process under the restoring force of the pressing spring 334, so that the sand core body 5 can be better protected from the direct force impact, and the sand core body 5 in the transport process can be better protected.

[0073] In addition, the supporting air bag 32 is used as the supporting structure, and the surface of the supporting air bag 32 is relatively smooth, so that the surface of the supporting air bag 32 is relatively easy to clean when there is no clamping operation, and the subsequent supporting operation is not affected by the supporting residues on the surface.

[0074] The above describes one embodiment of the present application in detail, but the content is only a preferred embodiment of the present application, and cannot be considered as limiting the implementation range of the present application. Any equivalent changes and improvements made according to the scope of the present application should still belong to the patent coverage range of the present application.
