Therefore, a new type of casting mold hoisting balancing device is proposed. Summary of the invention

[0003] In view of the deficiencies of the prior art, the present invention provides a novel casting mold hoisting balancing device, which solves the problem that the traditional casting mold hoisting method is often difficult to ensure the balance of the mold during the hoisting and moving process.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a novel casting mold hoisting balancing device, comprising a balancing base, a hoisting plate vertical plate fixedly connected to the top of the balancing base, an adjusting component arranged inside the hoisting plate vertical plate, a mounting plate rotatably connected to the bottom of the balancing base, three ear shafts rotatably connected inside the mounting plate, three fixing bolts fixedly connected to the outer wall of the mounting plate, a fixing component arranged inside the fixing bolts, an observation component arranged on the top of the balancing base, and an extrusion component arranged inside the balancing base;

[0005] The adjustment assembly includes a rotating shaft and a turning handle, both of which are rotatably connected to the inside of the hanging plate vertical plate, a first bevel gear is fixedly connected to the outer wall of the rotating shaft, a second bevel gear is fixedly connected to the turning handle, and the bottom of the rotating shaft is fixedly connected to the top of the mounting plate.

[0006] Preferably, the fixing assembly includes a positioning pin and a plurality of positioning holes, the outer wall of the positioning pin is slidably connected to the inside of the fixing bolt, the positioning hole is opened on the outer wall of the ear shaft, and the positioning pin and the positioning hole are engaged with each other.

[0007] Preferably, the observation assembly includes three liquid storage tanks, the liquid storage tanks are fixedly connected to the top of the balancing base, the outer walls of the liquid storage tanks are fixedly connected with flow guide tubes, and one end of the flow guide tube away from the liquid storage tanks is fixedly connected with an observation tube.

[0008] Preferably, the extrusion assembly includes three sliding rods, the outer wall of the sliding rod is slidably connected to the balancing base and the interior, the outer wall of the sliding rod is fixedly connected to a limiting block, the top of the limiting block is fixedly connected to a spring, and the top of the sliding rod is fixedly connected to a sliding plate.

[0009] Preferably, a shackle is fixedly connected to the top of the vertical plate of the lifting plate, and the first bevel gear and the second bevel gear are meshed.

[0010] Preferably, a fixing pin is slidably connected to the edge of the handle surface, and the fixing pin is engaged with the vertical plate of the hanging plate.

[0011] Preferably, the surface of the observation tube is provided with a scale, and the surface of the liquid storage tank is provided with an exhaust hole.

[0012] Preferably, a sealing ring is fixedly connected to the outer wall of the sliding plate, and the outer wall of the sealing ring is in abutment with the inner wall of the liquid storage tank.

[0013] Preferably, the outer wall of the limit block is slidably connected to the inside of the balancing base, and one end of the spring away from the limit block is fixedly connected to the inner wall of the balancing base.

[0014] Preferably, the outer wall of the ear shaft is rotatably connected to the inside of the fixing bolt.

[0015] The present invention provides a novel casting mold hoisting balancing device, which has the following beneficial effects:

[0016] 1. The present invention cooperates with each other through the rotating shaft, the first bevel gear, the handle and the second bevel gear in the adjustment component. When the operator turns the handle, the second bevel gear drives the first bevel gear to rotate, thereby rotating the rotating shaft. Since the bottom of the rotating shaft is fixedly connected to the top of the mounting plate, the mounting plate can be flexibly rotated around the rotating connection point between it and the balance base. The positions of the three ear shafts that are rotatably connected inside the mounting plate change with the rotation of the mounting plate. When facing casting molds of different shapes, sizes and weights, the relative position of the ear shafts can be adjusted to accurately adjust the hanging angle of the mold, ensure that the center of gravity of the mold is consistent with the force center of the lifting device, effectively prevent the shaking and imbalance of the mold caused by the displacement of the center of gravity, and greatly improve the stability and safety of the lifting.

[0017] 2. The present invention cooperates with each other through the slide bar, block limit block, spring and slide plate in the extrusion assembly. During hoisting, the mold squeezes the slide bar to make the slide bar slide in the balance base, drive the limit block to move and make the slide plate slide in the liquid storage tank. The sliding of the slide plate in the liquid storage tank changes the distribution of the liquid in the liquid storage tank. The liquid flows to the observation tube through the guide tube. The scale on the surface of the observation tube can accurately display the liquid level change. Through this linkage, the operator can intuitively judge whether the mold is parallel based on the difference in the liquid level in the observation tube, and realize real-time and accurate monitoring of the balance state of the mold. If the mold is tilted, the liquid level change will be fed back in time, and the operator can take measures to adjust it quickly, which effectively avoids safety accidents and mold damage caused by the failure to discover the imbalance of the mold in time, and ensures the smooth progress of the hoisting operation.

[0027] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example:

[0029] Please refer to the attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides a novel casting mold hoisting balancing device, including a balancing base 1. The balancing base 1 serves as the basic supporting structure of the entire device, bears the weight of the upper components and various forces received during the hoisting process, and provides a stable installation foundation for the entire device to ensure that there will be no imbalance or shaking problems due to unstable foundation when hoisting the mold. The top of the balancing base 1 is fixedly connected with a hoisting plate upright 2, and an adjustment component is arranged inside the hoisting plate upright 2. The adjustment component can adjust the position of the mounting plate 4 to adapt to different hoisting requirements or the adjustment of the balance state. The bottom of the balancing base 1 is rotatably connected with a mounting plate 4. The rotatable connection between the mounting plate 4 and the balancing base 1 enables the mounting plate 4 to flexibly rotate relative to the balancing base 1 when the center of gravity of the mold is offset or the hoisting angle needs to be adjusted, thereby achieving a certain degree of adaptive adjustment. The mounting plate 4 is rotatably connected inside Ear shafts 5, three ear shafts 5 can be used to connect lifting tools such as lifting chains or ropes, and their rotation characteristics in the mounting plate 4 can better adapt to the dynamic changes of the mold during the lifting process. The outer wall of the mounting plate 4 is fixedly connected with three fixing bolts 6, and the fixing bolts 6 play an auxiliary fixing and positioning role for the ear shafts 5 to ensure that the ear shafts 5 will not be displaced or shaken at will during normal operation. A fixing component is arranged inside the fixing bolts 6, and the fixing component can firmly lock the ear shafts 5 in a specific position when necessary to prevent unnecessary rotation. An observation component is arranged on the top of the balancing base 1. The observation component facilitates the operator to intuitively understand whether the hoisted mold is in a horizontal state, so as to make timely adjustments or judge whether the device is in a normal working state. An extrusion component is arranged inside the balancing base 1. The extrusion component can generate a specific force or displacement change during the operation of the device to push the observation component to operate;

[0030] Please refer to the attached Figure 4 and attached Figure 5The adjusting component includes a rotating shaft 9 and a turning handle 11, both of which are rotatably connected to the inside of the lifting plate vertical plate 2. The rotating connection mode of the rotating shaft 9 and the turning handle 11 enables the operator to drive the rotating shaft 9 to rotate by operating the turning handle 11, thereby realizing indirect control of other related components. A first bevel gear 10 is fixedly connected to the outer wall of the rotating shaft 9, and a second bevel gear 12 is fixedly connected to the turning handle 11. The bottom of the rotating shaft 9 is fixedly connected to the top of the mounting plate 4. When the turning handle 11 is rotated, the second bevel gear 12 on the turning handle 11 will drive the first bevel gear 10 meshing therewith to rotate, thereby rotating the rotating shaft 9. Since the bottom of the rotating shaft 9 is fixedly connected to the top of the mounting plate 4, the mounting plate 4 will adjust its angle as the rotating shaft 9 rotates. In this way, the angle of the mounting plate 4 can be accurately adjusted to adapt to the center of gravity distribution or lifting environment of different molds, thereby achieving a better lifting balance effect.

[0031] Please refer to the attached Figure 3 The fixing assembly includes a locating pin 7 and a plurality of locating holes 8. The outer wall of the locating pin 7 is slidably connected to the inside of the fixing bolt 6. The locating hole 8 is opened on the outer wall of the ear shaft 5. The locating pin 7 and the locating hole 8 are engaged with each other. When the ear shaft 5 needs to be fixed, the operator can slide the locating pin 7 inside the fixing bolt 6 to insert it into the locating hole 8 on the outer wall of the ear shaft 5, thereby realizing a rigid connection between the ear shaft 5 and the fixing bolt 6, effectively preventing the ear shaft 5 from accidentally rotating during operation, and ensuring the stability and safety of lifting.

[0032] Please refer to the attached Figure 6 The observation assembly includes three liquid storage tanks 17, which are fixedly connected to the top of the balancing base 1. A guide tube 18 is fixedly connected to the outer wall of the liquid storage tank 17, and an observation tube 19 is fixedly connected to the end of the guide tube 18 away from the liquid storage tank 17. A specific liquid medium can be stored in the liquid storage tank 17. When the device is in different equilibrium states or is subjected to different forces, the liquid will produce corresponding flow or liquid level changes between the liquid storage tank 17, the guide tube 18 and the observation tube 19. The operator can indirectly judge the balance of the device by observing the liquid level height of the liquid in the observation tube 19, so as to discover potential problems in time and make adjustments.

[0033] Please refer to the attached Figure 7 The extrusion assembly includes three slide bars 14, the outer wall of the slide bar 14 is slidably connected to the balance base 1 and the interior, the outer wall of the slide bar 14 is fixedly connected to the limit block 15, the top of the limit block 15 is fixedly connected to the spring 16, and the top of the slide bar 14 is fixedly connected to the sliding plate 21. During the operation of the device, when subjected to external force or the internal structure changes, the slide bar 14 will slide inside the balance base 1, and the limit block 15 will move with the slide bar 14 and compress or stretch the spring 16, while driving the sliding plate 21 to slide.

[0034] Please refer to the attached Figure 1 and attached Figure 2 A shackle 3 is fixedly connected to the top of the lifting plate vertical plate 2, and the shackle 3 can be conveniently connected to the hook of the lifting equipment to achieve a reliable connection between the entire lifting balancing device and the lifting power source, so that the mold can be smoothly lifted and moved. The first bevel gear 10 and the second bevel gear 12 are meshed, and the meshing relationship ensures that the rotation of the handle 11 can be accurately transmitted to the rotating shaft 9, thereby achieving precise control of the angle of the mounting plate 4 and improving the adjustment accuracy and reliability of the device.

[0035] Please refer to the attached Figure 5 The edge of the surface of the turning handle 11 is slidably connected with a fixing pin 13, and the fixing pin 13 is engaged with the vertical plate 2 of the hanging plate. When the angle of the mounting plate 4 is adjusted, the fixing pin 13 can be slid to engage with the vertical plate 2 of the hanging plate, thereby locking the position of the turning handle 11 to prevent the turning handle 11 from accidentally rotating and causing the angle of the mounting plate 4 to change, further improving the stability and safety of the device during operation.

[0036] Please refer to the attached Figure 6 The surface of the observation tube 19 is provided with a scale, and the setting of the scale enables the operator to read the liquid level height and other parameters in the observation tube 19 more accurately, so as to more accurately judge the degree of change in the balance state of the device. The surface of the liquid storage tank 17 is provided with an exhaust hole, and the exhaust hole can ensure that the inside of the liquid storage tank 17 is connected with the outside atmosphere, so as to avoid abnormal pressure in the liquid storage tank 17 due to liquid flow or temperature change, etc., which affects the normal flow of the liquid and the accuracy of the observation component.

[0037] Please refer to the attached Figure 7 and attached Figure 8 The outer wall of the sliding plate 21 is fixedly connected with a sealing ring 20, and the outer wall of the sealing ring 20 is in contact with the inner wall of the liquid storage tank 17. The sealing ring 20 can effectively prevent the liquid from leaking from the gap between the sliding plate 21 and the inner wall of the liquid storage tank 17, thereby ensuring the sealing of the liquid in the liquid storage tank 17, ensuring that the observation component can work normally, and accurately reflecting the balance state of the device.

[0038] Please refer to the attached Figure 7 The outer wall of the limit block 15 is slidably connected to the inside of the balancing base 1, and the end of the spring 16 away from the limit block 15 is fixedly connected to the inner wall of the balancing base 1. The connection method enables the spring 16 to stably exert its elastic effect inside the balancing base 1, so that the limit block 15 slides more smoothly inside the balancing base 1, which is beneficial to the effective adjustment of the extrusion assembly to the balance of the device.

[0039] Please refer to the attached Figure 3The outer wall of the ear shaft 5 is rotatably connected to the inside of the fixing bolt 6, allowing the ear shaft 5 to rotate relative to the fixing bolt 6 within a certain range to adapt to dynamic changes during the lifting process. When the fixing assembly works, the positioning pin 7 and the positioning hole 8 are engaged to limit the rotation of the ear shaft 5, thereby ensuring the stability and safety of the lifting.

[0040] Working principle: In the initial state, the components of the device are in a relatively static position. When the mold needs to be hoisted, first reliably connect the hook of the hoisting device with the shackle 3 on the top of the hoisting plate vertical plate 2.

[0041] If the center of gravity of the mold is unevenly distributed or there is a tendency to tilt during the hoisting process, the operator can adjust the angle of the mounting plate 4 by turning the handle 11. When the handle 11 is turned, the second bevel gear 12 fixedly connected thereto drives the first bevel gear 10 on the rotating shaft 9 meshing therewith to rotate, thereby rotating the rotating shaft 9. Since the bottom of the rotating shaft 9 is fixedly connected to the top of the mounting plate 4, the mounting plate 4 will rotate a certain angle around its rotating connection point with the balancing base 1. In this way, the relative positions of the three ear shafts 5 can be changed, thereby adjusting the hanging angle of the mold to adapt to the change in the center of gravity of the mold and achieve preliminary balance adjustment. After adjusting the angle, slide the fixing pin 13 on the edge of the surface of the handle 11 to engage it with the vertical plate 2 of the hoisting plate, lock the position of the handle 11, and prevent the angle of the mounting plate 4 from changing accidentally.

[0042] During the hoisting process, the gravity of the mold will squeeze the slide bar 14. Since the outer wall of the slide bar 14 is slidably connected to the inside of the balance base 1, and the top of the slide bar 14 is fixedly connected to the slide plate 21, and the bottom is in contact with the mold, when the center of gravity of the mold is unevenly distributed or changes position during the hoisting process, forces of different sizes and directions will be applied to the slide bar 14. Under the action of this force, the slide bar 14 will slide inside the balance base 1, and the limit block 15 fixedly connected to its outer wall will also move accordingly. The spring 16 connected to the top of the limit block 15 will be compressed or stretched due to the movement of the limit block 15, and the elastic reaction force generated by the spring 16 will act on the limit block 15 and then be transmitted to the slide bar 14 and the slide plate 21. When the slide plate 21 slides inside the liquid storage tank 17, the distribution state of the liquid in the liquid storage tank 17 will change. Because the liquid storage tank 17 is connected to the observation tube 19 through the guide tube 18, the change in liquid distribution will cause the change in the liquid level in the observation tube 19. The operator can determine whether the mold is in a parallel state by observing whether the liquid levels in the observation tubes 19 are consistent. If the liquid levels in the observation tubes 19 are the same, it means that the mold is in a parallel state; if there is a difference in the liquid levels, it means that the mold is tilted, so that the operator can know the parallel state of the mold in time and take corresponding adjustment measures as needed, such as adjusting the angle of the mounting plate 4 using the adjustment component, etc., to ensure the accuracy and safety of the lifting operation.

[0043] The present invention adopts the principle of three-point balance during hoisting, and fixes with fixing bolts 6 to achieve a balancing effect and an anti-slip effect. The present invention plays a role of balanced hoisting through fixing bolts 6; the existing hoist is not easy to balance before the balancing hoist of the present invention is used. After using the hoisting balancing device applicable to the present invention, it can maintain balance and increase safety. When hoisting sand cores for molding, the hoist has strict size requirements. The hoist must be lifted in a balanced manner during hoisting to prevent collisions. Therefore, the present invention is preferably used in the application scenario of hoisting sand cores for molding.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
