Description

Technical Field

[0001] The utility model relates to the technical field of mechanical casting, in particular to a sand box turning device. Background Art

[0002] In the sand box production process, the flipping of the sand box is a crucial link. At present, most operations use the cooperation of lifting equipment and simple flip bracket to realize the flipping of the sand box. The specific operation process is to first use the lifting equipment to lift the sand box to the simple flip bracket, and then use manual force to push the sand box to flip. In this process, the lifting equipment keeps the balance of the sand box by lifting the connecting ears on the surface of the sand box.

[0003] However, this traditional flipping method has many shortcomings. Due to the limited operating angle of the lifting equipment, the flipping of the sand box cannot be completed in one go. After one side of the sand box is flipped, the sand box must be supported manually, and then the lifting equipment must be connected to the connecting ear on the other side of the sand box for the next round of flipping. This operation method is not only time-consuming and labor-intensive, but also inefficient.

[0004] In addition, since the flipping process mainly relies on human power, and the sand box itself is heavy and square in shape, it is difficult to maintain balance. Once unbalanced, it is difficult to hold the sand box by human power, causing the corners of the sand box to hit the ground, which may cause the sand box to crack and fall off. At the same time, the impact force during flipping may also cause damage to the workshop floor, hoisting equipment and driving, and even endanger the safety of personnel. Utility Model Content

On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0028] A sand box turning device according to an embodiment of the utility model will be described below in conjunction with the accompanying drawings.

[0029] like Figure 1-Figure 4 As shown, a sand box turning device according to an embodiment of the utility model may include a bracket assembly 1, an axis support assembly 2, a turning auxiliary assembly 3 and an electric control assembly 5.

[0030] The bracket assembly 1 may include a left bracket 11 and a right bracket 12 , wherein the left bracket 11 and the right bracket 12 are respectively arranged on the ground and have corresponding positions.

[0031] The shaft support assembly 2 may include two groups of support shaft seats 21 and two groups of jacking cylinders 22 .

[0032] Among them, the two groups of support shaft seats 21 are respectively slidably connected to the inner walls of the left bracket 11 and the right bracket 12, and the two groups of lifting cylinders 22 are respectively fixedly connected to the inner walls of the left bracket 11 and the right bracket 12. One end of the two groups of lifting cylinders 22 passes through the top of the left bracket 11 and the top of the right bracket 12, and are fixedly connected to the bottom of the two groups of support shaft seats 21.

[0033] The flip auxiliary component 3 may include two groups of hydraulically driven rotating mechanisms 31, two groups of adjustable bracket mechanisms 32 and multiple groups of positioning rods 33, wherein the two groups of hydraulically driven rotating mechanisms 31 are respectively fixedly connected to the surface of the left bracket 11 and the surface of the right bracket 12, and are sleeved on the outside of the support shaft seat 21, the two groups of adjustable bracket mechanisms 32 are respectively fixedly connected to the surfaces of the two groups of hydraulically driven rotating mechanisms 31, and the two groups of adjustable bracket mechanisms 32 are connected by multiple groups of positioning rods 33.

[0034] The electric control assembly 5 is disposed on the surface of the right bracket 12 and is electrically connected to the two groups of jacking cylinders 22 and the two groups of hydraulically driven rotating mechanisms 31 respectively.

[0035] Specifically, the operation of the jacking cylinder 22 is controlled by the electronic control component 5, and the operation of the jacking cylinder 22 drives the support shaft seat 21 to rise to a set height, so as to adapt to the specifications of the sand box and support the sand box.

[0036] Then, the sand box to be turned over is hoisted between the left bracket 11 and the right bracket 12 by a hoisting device, and the positioning shaft of the sand box is placed in the supporting shaft seat 21 .

[0037] After placement, the sand box is kept in a horizontal state by means of the hoisting equipment as much as possible, and then the electronic control component 5 is used to control the operation of the adjusting bracket mechanism 32, and the adjusting bracket mechanism 32 is operated to adjust the positions of the two sets of support plates 322 to match the specifications of the sand box.

[0038] After the positions of the two groups of support plates 322 are adjusted, the controller 53 controls the operation of the liquid-driven rotating mechanism 31, and the operation of the liquid-driven rotating mechanism 31 synchronously drives the adjusting bracket mechanism 32 to rotate, and the rotation of the adjusting bracket mechanism 32 synchronously drives the two groups of support plates 322 to rotate. When the positioning holes 323 on the two groups of support plates 322 are aligned with the connecting ears on the sand box, one end of the positioning rod 33 is passed through the inside of the positioning hole 323 on the right bracket 12, and then through the connecting ears on the sand box, and finally abuts against the inner wall of the positioning hole 323 on the left bracket 11, and then the positioning rod 33 is rotated to be screwed and fixed with the positioning hole 323 on the right bracket 12, and the connecting ears on the surface of the sand box are supported and limited by the positioning rod 33, so that the sand box is installed on the adjusting bracket mechanism 32.

[0039] Then, the controller 53 is used to control the operation of the hydraulic drive rotating mechanism 31. The operation of the hydraulic drive rotating mechanism 31 synchronously drives the adjusting support mechanism 32 and the sand box to flip 180° and make them in a horizontal state. Then, the controller 53 is used to control the jacking cylinder 22 to reset. The reset of the jacking cylinder 22 synchronously drives the support shaft seat 21 to reset. The reset support shaft seat 21 synchronously drives the flipped sand box to fall to the ground. Then, the positioning rod 33 is pulled out. Finally, the flipped sand box can be lifted away by the lifting equipment.

[0040] The device can stably flip the sand box without generating any impact during the flipping process, and can effectively protect the safety of personnel, sand boxes and workshop floors. It is suitable for sand boxes that are inconvenient to flip and sand boxes of various types and sizes, and is convenient for use in the production process and can also ensure safety.

[0043] It should be noted that the hollow rotating platform 3111 and the hydraulic motor 3112 described in this embodiment are both existing technologies and will not be described in detail here.

[0044] Specifically, the controller 53 controls the operation of the hydraulic motor 3112, and the operation of the hydraulic motor 3112 drives the hollow rotating platform 3111 to rotate. The rotation of the hollow rotating platform 3111 synchronously drives the support frame 312 to rotate. The rotation of the support frame 312 synchronously drives the support plate 322 and the positioning rod 33 to move. The movement of the support plate 322 and the positioning rod 33 synchronously drives the sand box to flip, and the use effect is good.

[0047] It should be noted that the support frame 312 described in this embodiment has a sliding groove on its surface for facilitating the sliding of the two groups of support plates 322 , and the two groups of support plates 322 move synchronously inward or outward in the sliding groove.

[0048] It should also be noted that an encoder is fixedly connected to the surface of the drive motor 3211, and the encoder is used to detect the number of rotations of the drive motor 3211 in real time and send data information to the controller 53, which determines the positions of the two groups of support plates 322 based on the number of rotations.

[0049] Specifically, the controller 53 controls the driving motor 3211 to be powered on and run. The driving motor 3211 is powered on and rotates synchronously to drive the bidirectional screw to rotate. The bidirectional screw rotates synchronously to drive the two groups of support plates 322 to move synchronously inward or outward on the surface of the support frame 312, thereby realizing size adjustment, facilitating adaptation to sand boxes of different specifications, and achieving good use effect.

[0050] In one embodiment of the present invention, Figure 4 As shown, the electric control assembly 5 may include a box 51 , a hydraulic pump station 52 and a controller 53 .
