Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipe production, in particular to an oil draining rack for seamless steel pipes. Background Art

[0002] Seamless steel pipes are common building consumables. The manufacturing process of seamless steel pipes includes hot rolling and cold drawing. The cold drawing of seamless steel pipes includes the following steps: round tube blank → heating → piercing → heading → annealing → pickling → oil coating (copper plating) → multi-pass cold drawing (cold rolling) → billet tube → heat treatment → straightening → hydrostatic test (flaw detection) → marking → warehousing.

[0003] When performing anti-rust oil coating, it is necessary to use a crane to place the seamless steel pipe in the oil tank. A large amount of oil adheres to the seamless steel pipe in the oil tank. When the seamless steel pipe is taken out of the oil tank for the next operation after the oil coating is completed, a large amount of oil will adhere to the seamless steel pipe, and a large amount of oil will drip from the seamless steel pipe during handling and subsequent operations, resulting in waste of oil. Content of the Utility Model

[0004] In order to reduce the waste of oil, the present application provides an oil draining rack for seamless steel pipes.

[0005] The oil draining rack for seamless steel pipes provided by the present application adopts the following technical solution:

[0006] An oil draining rack for seamless steel pipes includes a base and a main oil box. The base is inclined with a main oil groove, the base is provided with an oil box groove, the base is provided with an oil collecting groove, the oil collecting groove connects the oil box groove and the lowest end of the main oil groove, the main oil box is slidably arranged in the oil box groove and is arranged below the oil collecting groove, the base is provided with a placing groove communicated with the main oil groove, and the base is provided with a placing block.

[0007] By adopting the above technical solution, the top wall of the main oil box is open. After the seamless steel pipe coated with oil in the oil tank is hoisted out of the oil tank and placed on the base, one end of the seamless steel pipe is placed on the placing groove, and the other end of the seamless steel pipe is placed on the placing block. The excess oil on the seamless steel pipe will fall off the seamless steel pipe under the action of gravity and fall into the main oil groove below, and slide along the main oil groove and fall into the main oil box placed in the oil box groove through the oil collecting groove, completing the recovery of oil and reducing the waste of oil.

[0008] Preferably, the base is provided with side plates, the side plates are provided with moving grooves, moving blocks are slidably arranged in the moving grooves, the placing blocks are arranged on the moving blocks, and the side plates are provided with moving components for driving the moving blocks to move.

[0009] By adopting the above technical solution, the moving component drives the moving block to move, thereby driving the placing block to move, and further changing the distance between the placing block and the placing groove. When recovering oil, the position of the placing block can be conveniently adjusted according to the length specification of the seamless steel pipe, so that the oil draining rack can be used for oil recovery of seamless steel pipes with different length specifications, improving the applicability.

[0010] Preferably, the moving component includes a moving motor and a moving lead screw. The moving lead screw is rotatably arranged in the moving groove, penetrates through the moving block and is threadedly connected with the moving block. The moving motor is arranged on the side plate and is connected to the moving lead screw.

[0011] By adopting the above technical solution, when it is necessary to move the placing block, start the moving motor to drive the moving lead screw to rotate, thereby driving the moving block to move in the moving groove, and further driving the placing block to move, changing the distance between the placing block and the placing groove, so that it can be used for oil recovery of seamless steel pipes with different specifications.

[0012] Preferably, a secondary oil box is slidably arranged in the oil box groove, and the secondary oil box is arranged below the main oil box.

[0013] By adopting the above technical solution, both the secondary oil box and the main oil box are provided with open top walls. Since the oil moves slowly, when the main oil box is full of oil, in most cases, there is still oil moving in the main oil tank waiting to be recovered. At this time, it is necessary to replace the main oil box. When the main oil box is pulled out of the oil box groove for replacement, oil will drip onto the bottom wall of the oil box groove, causing waste. Therefore, a secondary oil box is slidably arranged in the oil box groove, and the secondary oil box is arranged below the main oil box. When the main oil box is pulled out for replacement or cleaning, the oil falls into the secondary oil box through the oil collecting groove for recovery, further reducing oil waste, and at the same time reducing the possibility of the inner wall of the oil box groove being polluted by oil, improving the cleanliness.

[0014] Preferably, positioning blocks are arranged on the inner wall of the oil box groove, and positioning grooves are arranged on the side walls of the main oil box and the secondary oil box. The positioning blocks are inserted into the positioning grooves.

[0015] By adopting the above technical solution, inserting the positioning blocks into the positioning grooves facilitates the installation of the main oil box and the secondary oil box, and at the same time positions the main oil box or the secondary oil box, improving the installation stability of the main oil box and the secondary oil box, reducing the possibility of oil overflow or dripping into the oil box groove due to the shaking of the main oil box or the secondary oil box during use, and reducing the possibility of oil waste.

[0016] Preferably, the base is provided with a fixing groove communicating with the oil box groove. A fixing block is slidably arranged in the fixing groove. The fixing block enters the oil box groove and abuts against both the main oil box and the sub-oil box. The fixing block is provided with a first fixing hole, and the inner wall of the fixing groove is provided with a second fixing hole. The fixing block is provided with a fixing rod, and the fixing rod passes through the first fixing hole and is inserted into the second fixing hole.

[0017] By adopting the above technical solution, the main oil box and the sub-oil box are abutted by the fixing block, and the fixing block is fixed by the fixing rod, thereby improving the stability of the positioning and fixing of the main oil box and the sub-oil box in the oil box groove, reducing the possibility that the main oil box or the sub-oil box shakes during use, resulting in oil spillage or dripping into the oil box groove, and reducing the possibility of oil waste.

[0018] Preferably, the fixing block is provided with a rotating shaft, and the inner wall of the fixing groove is provided with a rotating groove. The rotating shaft is slidably inserted into the rotating groove and can rotate in the rotating groove. The base is provided with an unfolding groove communicating with the fixing groove, and the fixing block can be inserted into the unfolding groove.

[0019] By adopting the above technical solution, when the main oil box or the sub-oil box needs to be replaced, first pull out the fixing rod, then slide the fixing block in the fixing groove and drive the rotating shaft to slide in the rotating groove until the rotating shaft abuts against the inner wall of the end of the rotating groove far from the main oil box. At this time, rotate the rotating shaft to drive the fixing block to rotate and insert into the unfolding groove. At this time, the fixing block is separated from the oil box groove, and the main oil box or the sub-oil box can be replaced. The operation is simple and convenient. At the same time, by inserting the rotating shaft into the rotating groove, the fixing block will not be separated from the base, thereby improving the convenience of use. After the replacement is completed, rotate the fixing block to drive the rotating shaft to rotate, so that the fixing block is separated from the unfolding groove and partially inserted into the oil box groove. Push the fixing block to move in the fixing groove and drive the rotating shaft to move in the rotating groove until the fixing block abuts against the main oil box and the sub-oil box, and insert the fixing rod through the first fixing hole and into the second fixing hole to complete the fixing.

[0020] Preferably, the placing block is provided with a drainage block, and the top wall of the drainage block is inclined.

[0021] By adopting the above technical solution, the drainage block is used to place one end of the seamless steel pipe. The top wall of the drainage block is inclined, reducing the possibility that the oil on the seamless steel pipe remains on the top wall of the drainage block and cannot be automatically recovered. The oil falling on the top wall of the drainage block will flow along the top wall of the drainage block under the action of gravity and fall into the lower main oil tank for recovery, improving the efficiency of oil recovery.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By setting a base, a main oil groove, a main oil box, an oil box groove, an oil collecting groove, a placement groove and a placement block, when it is necessary to drain and recycle the oil of seamless steel pipes, place the seamless steel pipes on the base so that the two ends of the seamless steel pipes are respectively placed on the placement block and the placement groove. The oil on the seamless steel pipes will fall into the main oil groove under the action of gravity and then fall into the main oil box in the oil box groove through the oil collecting groove for recycling, reducing the waste of oil;

[0024] 2. By setting side plates, moving grooves, moving blocks and moving components, according to the length specifications of seamless steel pipes, drive the moving blocks to move in the moving grooves on the side plates through the moving components, so as to change the distance between the placement blocks and the placement grooves to fit the length of the seamless steel pipes, so that this oil draining rack can be used for the oil recycling of seamless steel pipes with different lengths, improving the applicability;

[0025] 3. By setting positioning blocks, positioning grooves and auxiliary oil boxes, insert the positioning blocks of the oil box groove into the positioning grooves of the main oil box and the auxiliary oil box to improve the stability of the positioning and fixing of the main oil box and the auxiliary oil box, reduce the possibility of oil leakage caused by the skew of the main oil box or the auxiliary oil box. At the same time, by setting the auxiliary oil box, when the main oil box is full and needs to be replaced, the oil can be normally recycled in the auxiliary oil box, reducing the waste of oil.

[0034] The implementation principle of the seamless steel pipe oil draining rack in the embodiment of the present application is as follows: According to the length of the seamless steel pipe, the moving motor 41 is started to drive the moving lead screw 42 to rotate, thereby driving the moving block 22 to move, adjusting the distance between the placing block 23 and the placing groove 16. The two ends of the oil-coated seamless steel pipe are respectively placed on the top walls of the placing groove 16 and the drainage block 231. The oil on the surface of the seamless steel pipe will fall into the main oil tank 11 under the action of gravity and enter the main oil box 3 through the oil collecting tank 12 for recycling. When the main oil box 3 is filled with oil, the fixing rod 51 is pulled out, the fixing block 5 is pushed to move until the rotating shaft 52 abuts against the side wall of the rotating groove 142 far from the main oil box 3, and the fixing block 5 is rotated so that the fixing block 5 is disengaged from the oil box groove 13 and inserted into the unfolding groove 15. At this time, the main oil box 3 can be pulled out through the handle 33 for replacement. During this process, the oil dropped by the seamless steel pipe will fall into the sub-oil box 32 for recycling. By setting this oil draining rack, the redundant oil after the seamless steel pipe is oil-coated can be effectively recycled, reducing the waste of oil.

[0035] The above are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
