Description

Technical Field

[0001] The utility model relates to the field of coating production equipment, in particular to a high-position valve opening and closing tool for coating production. Background Art

[0002] In the coating production industry, the pipelines for raw material transportation are generally arranged on the top of the factory building. In order to ensure stable and reliable raw material transportation, the pipelines are minimized in bending. Especially for the position of the valves on the pipelines, they are also arranged on the horizontal pipelines, without bending the pipelines downward to assemble the valves to make the valve operation simple. Therefore, the valves are all arranged on the pipelines on the top of the factory building, about 3-4 meters above the ground. This makes the operation extremely inconvenient, and the cuboid-shaped valve shaft on the valve needs to be rotated by more than 90° to achieve complete opening and closing, which requires a large space during the rotation process of a 3-4-meter-long operating rod and is difficult to perform in a factory building full of equipment, affecting the efficiency of valve opening and closing. Content of the Utility Model

[0003] The utility model provides a high-position valve opening and closing tool for coating production to solve the above technical deficiencies, which can facilitate the operation of high-position valves on the pipelines on the top of the factory building, and can reduce the rotation amplitude required for the operating handle, reduce the space requirement, and improve the operation efficiency.

[0004] The utility model discloses a high-position valve opening and closing tool for coating production, which includes a flat plate-shaped operating body and an operating handle arranged on the operating body and extending downward. Three long holes penetrating the operating body are arranged on the operating body at intervals, and the long holes are in interference fit with the valve shaft of the high-position valve. The length direction of one long hole is horizontal, the length direction of one long hole is vertical, and the length direction of one long hole forms a 45° angle with the horizontal direction.

[0005] The long hole is composed of a tapered hole and a straight hole, and the smaller end of the tapered hole is butted against the straight hole. The tapered holes of the three long holes are all located on the same side of the operating body.

[0006] On the end face of the operating body on one side of the straight hole, three sliding grooves are arranged, and each sliding groove is arranged on the side of the corresponding long hole. A magnet is arranged at the end of the sliding groove close to the long hole, and the magnet is slidably connected in the sliding groove. The end of the sliding groove far from the long hole is a closed end. A spring is arranged between the closed end of the sliding groove and the magnet. In the natural state of the spring, part of the magnet is exposed within the range of the long hole. The two ends of the spring are respectively fixed to the magnet and the closed end of the sliding groove. A through hole is arranged at the closed end of the sliding groove, and the through hole is within the range of the spring and the diameter of the through hole is smaller than the inner diameter of the spring. A pull rope is arranged on the magnet, and the pull rope sequentially passes through the inside of the spring and the through hole and then extends to the operating handle.

[0007] A high-position valve opening and closing tool for paint production obtained by the present utility model uses three long holes on the operating body to cooperate with the valve shaft of the valve, and the directions of the three long holes are different, so that the valve can be opened and closed with a relatively small rotation range of the operating handle, which is convenient for operation.

[0012] In order to further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following combines the drawings and preferred embodiments to detail the specific embodiments, structures, features and their effects according to the present utility model as follows.

[0013] Embodiment 1:

[0014] As Figures 1-4 shown, the present utility model discloses a high-position valve opening and closing tool for paint production, including a flat operating body 1 and an operating handle 2 provided on the operating body 1 and extending downward. Three long holes 3 penetrating the operating body 1 are arranged at intervals on the operating body 1. The long holes 3 are inserted and cooperated with the valve shaft of the high-position valve. The length direction of one long hole 3 is horizontal, the length direction of one long hole 3 is vertical, and the length direction of one long hole 3 forms a 45° angle with the horizontal direction.

[0015] The operating body 1 is lifted to the same height as the valve by using the operating handle 2, so the length of the operating handle 2 can be selected according to actual requirements. The shape and size of the long hole 3 are matched with the valve shaft of the high-position valve. Generally, the cross-section of the valve shaft is in a quasi-rectangular structure. In this solution, the length direction of one of the long holes 3 is the horizontal direction, that is, this long hole 3 is horizontally arranged and is called the No. 1 long hole 3; the length direction of the other long hole 3 is the vertical direction, that is, this long hole 3 is vertically arranged and is called the No. 2 long hole 3; in addition, a long hole 3 is arranged with its length direction at an angle of 45° to the horizontal direction and is called the No. 3 long hole 3. That is, a 45° angle is formed between the No. 1 long hole 3 and the No. 3 long hole 3, a 45° angle is formed between the No. 2 long hole 3 and the No. 3 long hole 3, and a 90° angle is formed between the No. 1 long hole 3 and the No. 2 long hole 3. Under normal circumstances, the valve shaft of the high-position valve, such as in the closed state, its valve shaft is in a horizontal state, that is, the cuboid structure of the valve shaft is horizontal and corresponds to the No. 1 long hole 3. Then its valve shaft in the open state is in a vertical state and corresponds to the No. 2 long hole 3. So during actual operation, such as when the high-position valve is changed from the closed state to the open state, the No. 1 long hole 3 can be first sleeved on the valve shaft, then rotated about 45°, then the No. 3 long hole 3 is docked with the valve shaft, then rotated about 45° again, and finally the No. 2 long hole 3 is docked with the valve shaft and adjusted in place. When the high-position valve is changed from the open state to the closed state, the operation is just in the reverse order. In this structural form, during the operation of the high-position valve, the operating handle 2 only needs to swing within a range of 45°, and the whole process can be completed by repeating the swing twice. Therefore, the space requirement for the swing of the operating handle 2 is smaller, which is more convenient for operating the high-position valve. In the case where there are machine devices below the high-position valve and it affects the operation space, the operation efficiency can be greatly improved.

[0016] The long hole 3 is composed of a tapered hole 31 and a straight hole 32. The smaller end of the tapered hole 31 is docked with the straight hole 32. The tapered holes 31 of the three long holes 3 are all located on the same side of the operating body 1. The long hole 3 adopts the combination of the tapered hole 31 and the straight hole 32, that is, half of the long hole 3 in the depth direction is the straight hole 32 and half is the tapered hole 31, and the smaller end of the tapered hole 31 is docked with the straight hole 32, so that the size of the tapered hole 31 at the end of the operating body 1 is the largest and larger than the size of the straight hole 32. In this way, during the actual operation process, it is more convenient to sleeve the long hole 3 on the valve shaft of the high-position valve. Since the high-position valve is at a high position and the operator is below, it is easy to see the valve shaft above unclearly. Therefore, by using the tapered hole 31, it can be better sleeved on the valve shaft, and the docking is more accurate, convenient and fast.

[0017] On the end face of the operating body 1 on one side of the straight hole 32, three sliding grooves 6 are provided, and each sliding groove 6 is arranged on the side of the corresponding long hole 3. A magnet 4 is provided at one end of the sliding groove 6 close to the long hole 3. The magnet 4 is slidably connected in the sliding groove 6. The end of the sliding groove 6 away from the long hole 3 is a closed end. A spring 7 is provided between the closed end of the sliding groove 6 and the magnet 4. In the natural state of the spring 7, part of the magnet 4 is exposed within the range of the long hole 3. The two ends of the spring 7 are respectively fixed to the magnet 4 and the closed end of the sliding groove 6. A through hole 8 is provided at the closed end of the sliding groove 6. The through hole 8 is within the range of the spring 7, and the diameter of the through hole 8 is smaller than the inner diameter of the spring 7. A pulling rope 5 is provided on the magnet 4. The pulling rope 5 sequentially passes through the inside of the spring 7 and the through hole 8 and then extends to the operating handle 2.

[0018] A rubber layer is provided on the end face of the operating body 1 inside the sliding groove 6. Since it is necessary to forcefully fit the long hole 3 onto the valve shaft after the long hole 3 is aligned with the valve shaft, but there is a certain distance between the operating handle 2 held by the worker and the operating body 1, when applying force, because it is necessary to align the long hole 3 with the valve shaft, the difficulty is high and it is easy to cause the long hole 3 to tilt and the situation where the operating body 1 is stuck with the valve shaft. In the above solution, a magnet 4 is provided in the sliding groove 6. In the natural state, part of the magnet 4 is located at the end of the long hole 3. Therefore, after the long hole 3 is aligned with the valve shaft, when the two approach, they will be attracted by the magnet 4, and the valve shaft directly enters the long hole 3, without the need to apply additional thrust, and the operation is more convenient. When the rotation is in place, the corresponding pulling rope 5 can be pulled to overcome the elastic force of the spring 7 and pull the magnet 4 into the inside of the sliding groove 6, and the magnet 4 is separated from the valve shaft, so that the operating handle 2 can be moved to remove the operating body 1 from the valve shaft. Since during the removal process, there is no need to align, only an external force needs to be applied, and the operation is convenient.
