[0002] Large sand boxes are specialized tooling used in the casting of cast steel products. Each box weighs 2565 kg and has a maximum length of 3150 mm and a width of 2150 mm. Due to their high frequency of use in molding production and the harsh working environment, large sand boxes frequently experience problems such as broken straps or weld defects. They must be promptly isolated and moved to a repair area for repair work. During the operation, the overhead crane operators and ground workers cooperate with each other. One side of the large sand box needs to be secured to a ground beam, while the other side is lifted and tilted to the required angle for repair work. The chain on the overhead crane hook must not be removed during the operation; it must continuously assist the operators in repairing the large sand box into place.

[0003] However, due to the heavy weight and large size of the large sand boxes, there are many practical difficulties and problems during operation, the unstable safety factors of hoisting safety hazards are prominent, the labor intensity of operation is high, and the requirement of "human and machine isolation" safety protection cannot be achieved.

[0004] Therefore, how to completely eliminate operational safety hazards, achieve the "human-machine isolation" safety protection requirements, further improve operational efficiency, and reduce labor intensity and casting costs are urgent problems to be solved. Utility Model Content

[0005] This utility model provides a safety repair auxiliary device for large sand boxes, which can completely eliminate safety hazards during large sand box repair operations, achieve the safety protection requirements of "human and machine isolation", further improve operation and production efficiency, reduce labor intensity and casting costs, and promptly meet the casting production requirements of automated molding production lines for ester-hardened water glass sand, providing high-quality, low-cost, and short-time product demand.

[0006] To solve the above technical problems, this utility model provides a safety repair auxiliary device for large sandboxes, characterized in that: it includes a base 1, a hydraulic cylinder 2, and a tilting frame 3; one end of the tilting frame 3 is hinged to the base 1, and the hydraulic cylinder 2 is mounted on the base 1 with its end hinged to the tilting frame 3, used to push the tilting frame 3 to rotate to a specified required position; the large sandbox to be repaired is fastened to the tilting frame 3.

[0007] Furthermore, the large sand box is pressed and fixed onto the tilting frame 3 by multiple fixing screws.

[0008] Furthermore, the base 1 is also provided with a support frame 4, which is used to provide safety assistance to the tilting frame when the tilting frame 3 falls back to its original position.

[0009] Furthermore, the two hydraulic cylinders are symmetrically arranged on the base.

[0010] Furthermore, a safety lock plate is provided on the base, and a safety groove is provided at the end of the safety lock plate for engaging with the safety shaft on the tilting frame 3.

[0011] Furthermore, a visual pressure gauge for real-time oil pressure monitoring is installed on the hydraulic lines of the cylinder.

[0012] Furthermore, a reinforcing rib is welded on each side of the rotating part of each flipping frame 3.

[0013] Furthermore, when the tilting frame 3 rotates to the required repair position, the safety groove on the safety lock plate 5 fully engages with the safety shaft on the tilting frame 3.

[0016] 2. Improve the production efficiency of repairing large sandboxes. Using this large sandbox safety repair auxiliary device makes it easier to perform difficult flipping operations during the repair of large sandboxes, thus improving the actual production efficiency of the repair operation.

[0017] 3. Reduce casting production costs. Previously, repairing large sand boxes took 2 pieces per week and required real-time assistance from crane operators and personnel. Now, with the use of the large sand box safety repair auxiliary device, repairing large sand boxes takes 3.5 pieces per week, eliminating the need for real-time crane operator assistance and reducing repair costs.

[0018] 4. Eliminate safety hazards during the hoisting of large sandboxes. The use of this large sandbox safety repair auxiliary device completely eliminates the unstable safety factors affecting the coordination between overhead crane operators and ground workers.

[0019] 5. Reduce the labor intensity of operators. Using this large sandbox safety repair auxiliary device, the flipping operation can be easily realized when repairing large sandboxes, reducing the difficulty and intensity of flipping operations caused by the heavy weight and large size of the large sandboxes themselves.

[0020] 6. Meeting the needs of domestic and international customers. Using this large sand box safety repair auxiliary device improves the efficiency of repairing large sand boxes, ensuring timely production needs of the company's automated molding production line for ester-hardened water glass sand. This meets the demands of domestic and international cast steel product customers for short-time processing, quality optimization, and cost-effectiveness, thereby enhancing customer product quality satisfaction.

[0027] To make the purpose, content and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below.

[0028] The present invention proposes a safety repair auxiliary device for large sandboxes, comprising a base 1, a hydraulic cylinder 2, a tilting frame 3, a support frame 4, and a safety lock plate 5.

[0029] The main function of cylinder 2 is to use a hydraulic pressurizing device to simultaneously output equal pressure, equal speed, and equal distance hydraulic pressure from both the left and right sides to drive the tilting frame 3 to rotate to the designated position. The main function of tilting frame 3 is to support the large sand box to be repaired and to use three fixing screws to press the large sand box for secure fixation. The main function of support frame 4 is to provide safety assistance to tilting frame 3 when it falls back to its original position at 15°. Base 1 is the base for fixing two cylinders 2, tilting frame 3, and two safety lock plates 5, and four threaded through holes for fixing and lifting are designed at the four corners. When the tilting frame 3 with the large sand box fixed is rotated to the required working position, the safety lock plate 5 will completely lock the safety shaft on tilting frame 3 into the safety groove to prevent tilting frame 3 from tipping over.

[0030] Implementation Step 1:

[0031] Place the safety repair aid on a flat surface, pass it through the four threaded holes, and secure it firmly. Then place the large sandbox... Figure 3 The object is lifted by a crane and accurately placed on the tilting frame 3 by adjusting its position, angle and direction. Three fixing screws welded to the tilting frame 3 pass through the large sand box belt, and the belt is pressed with the matching pressure iron on the fixing screws. The nuts are then rotated and fully tightened.

[0032] Implementation Step Two:

[0033] The electro-hydraulic pressurization device is activated, transmitting pressure through hydraulic pipelines to two cylinders 2. Simultaneously, equal pressure, constant speed, and equal distance are output from both the left and right sides, pushing the tilting frame 3 to the designated position. The rotating ends of the two cylinders 2 are connected to the base 1 via pins, and a visual pressure gauge for real-time oil pressure monitoring is installed on the hydraulic pipelines. The rotating parts of the tilting frame 3 are connected to the base 1 via pins at two points. A reinforcing rib is welded to each side of the rotating part of the tilting frame 3.

[0034] Step 3:

[0035] When the tilting frame 3 is rotated to the required repair position, the safety groove on the safety lock plate 5 is fully engaged with the safety shaft on the tilting frame 3 to prevent the tilting frame 3 from tipping over during the repair operation. The rotating part of the safety lock plate 5 is connected to the base 1 by a pin, in two places.

[0036] Step 4:

[0037] After the large sandbox repair work is completed, the support frame 4 is placed stably in the fixed position, the safety lock plate 5 is removed and returned to its original position, and the hydraulic pressure in the pipeline of the electric hydraulic pressurization device is released. The tilting frame 3 is rotated back to the initial 15° position. At this time, the support frame 4 supports the tilting frame 3 to prevent damage to the oil cylinder 2.

[0038] Key features of this utility model:

[0039] 1. Large sandboxes must be securely fastened when placed on the safety repair auxiliary device. Place the large sandbox... Figure 3 The object is lifted by a crane and accurately placed on the tilting frame 3 by adjusting its position, angle and direction. Three fixing screws welded to the tilting frame 3 pass through the large sand box belt, and the belt is pressed with the matching pressure iron on the fixing screws. The nuts are then rotated and fully tightened.

[0040] 2. The left and right cylinders simultaneously output equal pressure, equal speed, and equal distance hydraulic pressure. Activate the electro-hydraulic pressurizing device, which transmits pressure to the two cylinders 2 via hydraulic pipelines. The left and right cylinders simultaneously output equal pressure, equal speed, and equal distance hydraulic pressure, pushing the tilting frame 3 to rotate to the designated position.

[0041] 3. The slot on the safety lock plate is fully engaged with the safety shaft on the tilting frame. When the tilting frame 3 is rotated to the required repair position, the safety slot on the safety lock plate 5 is fully engaged with the safety shaft on the tilting frame 3 to prevent the tilting frame 3 from tipping over during the repair operation.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
