Description

Technical Field

[0001] The utility model relates to a three-point support type clamp used for clamping an oil drum, and belongs to the technical field of clamps. Background Art

[0002] In the installation, testing and use of some large-scale construction machinery, hydraulic oil, gear oil and coolant are used in particularly large quantities. Nowadays, the sizes and models of oil drums used to hold hydraulic oil, gear oil and coolant are similar, which makes it possible to design a unified type of oil drum clamp to assist in convenient, fast and safe handling of oil drums. At the same time, in order to avoid the safety risks caused by uncertain factors, the increase in sunk costs caused by time and effort, and the pollution of the working environment caused by operational errors during manual handling, it is also necessary to continuously improve the existing oil drum clamping fixtures. The oil drum clamping fixture is a mechanical mechanism used to carry oil drums. The existing oil drum clamps are mainly divided into two types according to the clamping method: embracing type and lifting type, and there are certain limitations in use:

[0003] Disadvantages of the wraparound oil drum clamp: 1. The application site is limited. The opening and closing of the clamp requires more space, which is not conducive to the stacking of oil drums and the use in small spaces; 2. Insufficient control of the clamping force. When clamping an oil drum that is not fully filled or unsealed, it is challenging to accurately control the clamping force. Excessive clamping force can easily damage the oil drum or cause oil spills; insufficient clamping force can cause the oil drum to slip; 3. The manufacturing cost is relatively high. Wraparound clamps are mostly used for custom design and manufacturing, and are used in conjunction with existing equipment and facilities. Due to the special use scenario, the manufacturing cost has increased.

[0004] Disadvantages of lifting oil drum clamps: Compared with embracing clamps, lifting clamps are more practical. At present, lifting clamps are mainly divided into two-point and four-point types. Two-point clamps usually select two points corresponding to the diameter of the oil drum contact surface as hook points. The balance is difficult to control during transportation and lacks safety. Although the four-point clamp improves the uniformity of load distribution to a certain extent, improves the stability and anti-tilt of the clamp, it makes the clamp mechanism more complicated, increases daily inspections, and increases the workload of maintenance and repair. At the same time, under the premise of ensuring the balance of clamping, one more point will reduce the flexibility of the clamp. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a three-point support type oil drum clamp with strong stability, good flexibility, high safety and low cost investment in view of the defects in the prior art.

[0006] To solve this technical problem, the present utility model provides a three-point support type fixture for clamping an oil barrel, which includes a three-pronged stabilizing frame, a positioning plate, a lifting hanger, a connecting pin one, and a connecting pin two. The three-pronged stabilizing frame is a three-point support structure and is located at the bottom of the fixture. Three positioning plates are connected to the three-pronged stabilizing frame through the connecting pin two. The lifting hanger is connected to the positioning plate through the connecting pin one to form an oil barrel clamping fixture, and lifting is achieved by lifting the hook ring of the lifting hanger.

[0007] The three-pronged stabilizing frame includes stabilizing frame connecting rods, stabilizing frame teeth, and stabilizing frame reinforcing rib plates. Each fork of the stabilizing frame connecting rod is evenly distributed at 120°; stabilizing frame teeth are provided below each fork edge, and the stabilizing frame teeth bite into the inner circle of the oil barrel to form a stabilizing effect.

[0008] The positioning plate includes a long side of the positioning plate and a hook of the positioning frame. The long side of the positioning plate and the hook of the positioning frame form a 60-degree corner, and the corner part is connected to the stabilizing frame connecting rod; three hooks of the positioning frame are used to hook on the outer edge of the hydraulic oil barrel.

[0009] The lifting hanger includes a hook ring of the lifting hanger, a positioning part of the lifting hanger, and a travel track of the lifting hanger. There are three positioning parts of the lifting hanger, which are evenly distributed at 120°; the positioning part of the lifting hanger is connected to the long side of the positioning plate through the connecting pin one; the trajectory formed by the hook ring of the lifting hanger during lifting is restricted within the travel track of the lifting hanger.

[0010] A stabilizing frame reinforcing rib plate is welded to the lower part of the stabilizing frame connecting rod to enhance the strength of the three-pronged stabilizing frame.

[0011] Beneficial effects: The structure of the present utility model is simple, has good stability, strong applicability, and low manufacturing cost. During the actual handling process, it is not necessary to frequently rotate or operate the oil barrel at multiple angles, reducing the direct participation of manual labor and improving work efficiency.

[0019] The following specifically describes the present utility model in conjunction with the accompanying drawings and embodiments.

[0020] As Figures 1-6 shown, the present utility model provides a three-point support type fixture for clamping an oil barrel, including a three-pronged stabilizer 2, a positioning plate 3, a lifting hook 4, a connecting pin 1 5 and a connecting pin 2 6. The three-pronged stabilizer 2 is a three-point support structure and is located at the bottom of the fixture. Three positioning plates 3 are connected to the three-pronged stabilizer 2 through the connecting pin 2 6. The lifting hook 4 is connected to the positioning plate 3 through the connecting pin 1 5 to form an oil barrel clamping fixture, and the lifting is realized by lifting the hook ring 41 of the lifting hook.

[0021] The three-pronged stabilizer 2 includes a stabilizer connecting rod 21, stabilizer teeth 22 and a stabilizer reinforcing rib plate 23. Each fork of the stabilizer connecting rod 21 is evenly distributed at 120°, which is the key to the three-point support. Stabilizer teeth 22 are provided below each fork edge, and the stabilizer teeth 22 bite on the inner circle of the oil barrel to form a stabilizing effect.

[0022] The positioning plate 3 includes a long side 31 of the positioning plate and a hanging hook 32 of the positioning frame. The long side 31 of the positioning plate and the hanging hook 32 of the positioning frame form a 60-degree corner, and the corner part is connected to the stabilizer connecting rod 21. The three hanging hooks 32 of the positioning frame are used to hook on the outer edge of the hydraulic oil barrel.

[0023] The lifting hook 4 includes a hook ring 41 of the lifting hook, a positioning part 42 of the lifting hook and a stroke track 43 of the lifting hook. There are three positioning parts 42 of the lifting hook, which are evenly distributed at 120°; the positioning part 42 of the lifting hook is connected to the long side 31 of the positioning plate through the connecting pin 1 5; the trajectory formed by the hook ring 41 of the lifting hook during the lifting process is limited within the stroke track 43 of the lifting hook.

[0024] A stabilizer reinforcing rib plate 23 is welded to the lower part of the stabilizer connecting rod 21 to improve the strength of the three-pronged stabilizer 2 and avoid bending and deformation.

[0025] When the lifting frame 4 is in a relaxed state, the first connecting pin 5 is at the upper part of the travel track 43 of the lifting frame. At this time, the three positioning edges are in an open state. When lifting an oil barrel, by applying an upward force to lift the lifting frame 41, the hook 32 is hooked on the outer edge of the oil barrel, presenting a clamping state. The first connecting pin 5 of the positioning part 41 of the lifting frame is at the lower part of the travel track 43 of the lifting frame. Due to the gravity of the oil barrel, an upward force appears on the hook 32, and the positioning plate 31 clamps the oil barrel, enabling the lifting device to carry the oil barrel freely in the air.

[0026] In the present utility model, one end of the positioning plate that plays a major hooking role is connected to the three - pronged stabilizing frame, which is the key to the three - point support type fixture. It evenly distributes the gravity of the oil barrel onto the three positioning plates, achieving the effects of clamping firmly and uniform stress.

[0027] When hoisting with the present utility model, the hanging nose can be replaced according to the mechanical equipment (such as forklifts, overhead cranes) suspended outside the lifting frame. After the external mechanical equipment is lifted, the oil barrel is separated from the contact surface where it is placed, realizing the precise and stable movement and placement of the oil barrel.

[0028] The above - mentioned implementation schemes of the present utility model are only examples, not the only ones. All changes within the scope of the present utility model or equivalent to the scope of the present utility model are encompassed by the present utility model.
