[0001] The invention relates to the field of oil drum auxiliary tools, and more particularly to an oil drum turning device. Background Art

[0002] Loading and unloading equipment refers to machinery used to move, lift, load and unload materials or goods over short distances. Loading and unloading equipment is the basis for mechanization of loading and unloading operations and is an important mechanical equipment in logistics equipment. It can not only be used to complete the loading and unloading of ships and vehicles, but also to complete the stacking, destacking, transportation of goods in the warehouse, as well as the lifting, transportation and handling of goods in the cabin, vehicle and warehouse.

[0003] In order to pour out the oil in the oil barrel, many devices for dumping the oil barrel are provided in the prior art. However, there is a common problem that the angle of dumping the oil barrel is small, which makes the remaining amount of oil in the oil barrel large, thus easily causing waste of oil. Summary of the invention

[0004] The present invention overcomes the problem of the oil barrel tipping device in the prior art that the angle of the oil barrel tipping is small, resulting in a large amount of oil remaining in the oil barrel and causing a lot of oil waste. An oil barrel flipping device is provided, which can rotate the oil barrel 360 degrees so that the oil in the oil barrel can be completely poured out of the oil barrel, reducing oil waste.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solution: an oil drum turning device, comprising: A transport trolley provided with a flip bracket; A worm gear reducer is arranged on one side of the flip bracket; The flip assembly is arranged on the flip bracket, and the flip assembly includes a support arm, an arc-shaped flip frame arranged on both sides of the support arm, and a flip arm is arranged at the end of the arc-shaped flip frame, and the flip arm is connected to the output end of the worm gear reducer; a fixing plate with a pin and a rotatable locking block are respectively arranged at both ends of the support arm; when in use, one end of the oil drum abuts against the fixing plate, and the other end of the oil drum is fixed by the locking block.

[0006] The present invention cooperates by setting a flip bracket and a worm gear reducer, installing the oil barrel through the flip bracket, and then rotating the flip bracket through the worm gear reducer to realize the tipping of the oil barrel, so that the oil barrel can be flipped 360 degrees, so that the oil in the oil barrel can be completely dumped out, reducing oil waste; in addition, the two ends of the oil barrel are directly fixed on the support arm through a fixed plate and a locking block. The arc-shaped flip frame and the support arm form a clamp with an opening upward, and the arc-shaped flip frames on both sides protect and limit the oil barrel, which can prevent the transport trolley from tipping over due to the change of the center of gravity of the oil barrel.

[0007] Preferably, the worm gear reducer comprises a gearbox, an input rod connected to the gearbox input shaft and a gearbox output shaft; the gearbox output shaft is connected to the flip arm.

[0008] By rotating the input rod, the tilting arm can be tilted to pour out the oil in the oil barrel.

[0009] Preferably, a polygonal through hole is provided at the center of the output shaft of the gear box; a polygonal flip hole is provided on the flip arm; and the polygonal pin is connected to the nut after passing through the polygonal through hole and the polygonal flip hole.

[0010] The polygonal pin passes through the polygonal through hole and the polygonal flip hole and is connected with the nut, so that the polygonal pin plays a transmission role and can transmit the power of the gear box output shaft to the flip arm.

[0011] Preferably, a mounting plate is provided at one end of the input rod close to the gear box, a spring pin is provided on the mounting plate, and a locking hole cooperating with the spring pin is provided on the gear box.

[0014] When the locking pin abuts against the locking hole, the rotation of the input rod can be restricted, and this state is the locked state. When the disconnect state is required, the pin handle can be pulled so that the pin handle can overcome the force of the locking spring and slide in the long hole. When the cylindrical section slides into the long hole, the locking pin is disengaged from the locking hole. The locking pin is rotated so that the long hole section and the long hole are staggered, and then the hand is released.

[0022] Through the action of the first slider and the second slider, when the oil barrel moves, the inertia of the oil itself is utilized to enable the oil to flow downward as quickly as possible, so that the oil in the oil barrel can flow out more fully, further reducing the waste of oil in the oil barrel.

[0023] Preferably, the locking structure includes a fixing hole arranged on the fixing connecting rod and a fixing bolt threadedly matched with the fixing hole, and a locking through hole corresponding to the fixing hole is arranged on the supporting arm, and the fixing bolt passes through the locking through hole and is threadedly connected with the fixing hole.

[0045] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings: Example 1: Reference Figures 1 to 15 As shown, an oil drum turning device includes: a transport trolley 1, a worm gear reducer 2 and a turning assembly 4.

[0046] like Figures 1 to 3As shown, the transport trolley 1 is provided with a flip bracket 3. Specifically, the transport trolley 1 is a transport frame 11 supported on four transport wheels 12. The flip bracket 3 is provided at one end of the transport trolley 1, and the trolley handle 15 is provided at the other end. The end provided with the flip bracket 3 is the front section, and the end provided with the trolley handle 15 is the end section. The transport frame 11 is a non-closed structure composed of a long beam and a short beam. The front section of the transport frame 11 is open and is set as an open end 13 (without a short beam and a flat plate). The middle section and the end section of the transport frame 11 are provided with a reinforced short beam. The four supporting feet at the bottom end of the transport frame 11 are provided with transport wheels 12. The front end of the transport frame 11 is a directional transport wheel 12. The end of the transport frame 11 is a universal transport wheel 12. The upper end surface of the middle section and the end section of the transport frame 11 is provided with the folded steel plate 14, and the folded edge of the folded steel plate 14 faces upward. The upper end of the long beam at the open end 13 of the transport trolley 1 is provided with a flip bracket 3, and the flip bracket 3 is an isosceles trapezoidal closed frame. The top of the flip bracket 3 is provided with a flip bracket short beam 31, and the top of the flip bracket short beam 31 is provided with a detachable ear shaft support 32. The ear shaft support 32 is a vertical long strip of thick steel plate with a bottom plate. In this embodiment, a 20 mm thick carbon steel plate is used. A circular ear shaft support hole 33 is opened on the upper part of the ear shaft support 32, and the ear shaft support hole 33 is located in the middle position of the ear shaft support 32.

[0047] like Figure 5 and Figure 6 As shown, the worm gear reducer 2 is arranged on one side of the flip bracket 3. Specifically, the worm gear reducer 2 is arranged on the outside of the flip bracket 3. The worm gear reducer 2 includes a gear box 21, an input rod 22 connected to the input shaft of the gear box 21, and an output shaft of the gear box 21, and the output shaft of the gear box 21 is connected to the flip arm 43. A polygonal through hole 23 is arranged at the center of the output shaft of the gear box 21; a polygonal flip hole is arranged on the flip arm 43; and a polygonal pin 24 passes through the polygonal through hole 23 and the polygonal flip hole and is connected to a nut. Thus, the polygonal pin 24 plays a transmission role and can transmit the power of the output shaft of the gear box 21 to the flip arm 43. The polygonal through hole 23, the polygonal flip hole, and the polygonal pin 24 in this embodiment are all hexagonal.

[0048] In one embodiment, a mounting plate 25 is provided at one end of the input rod 22 close to the gear box 21, and a hand wheel 26 is provided at one end of the input rod 22 away from the gear box 21. A spring pin 5 is provided on the mounting plate 25, and a locking hole 211 cooperating with the spring pin 5 is provided on the gear box 21. The spring pin 5 includes a sleeve 51, in which a locking pin 52 is slidably provided; a locking spring 53 is provided in the sleeve 51 to push the locking pin 52 toward the locking hole. One end of the sleeve 51 is open, i.e., an open end 13, which is welded to the mounting plate 25, and the other end of the sleeve 51 is a closed end 511, in which a long hole 512 is provided, and the locking pin 52 is provided with a long hole section 521 having the same cross section as the long hole 512 and a cylindrical section 522 having the same width as the long hole 512; the end of the locking pin 52 away from the inner stopper passes through the long hole 512 and is fixedly connected to the pin handle 523. A locking protrusion 524 is provided in the circumferential direction of the locking pin 52 . The locking protrusion 524 slides in the sleeve 51 . Both ends of the locking spring 53 abut against the locking protrusion 524 and one end of the sleeve 51 away from the locking hole (the closed end 511 ) respectively.

[0049] like Figures 8 to 12 As shown, the spring pin 5 can be in a locked or disconnected state by pulling and rotating; specifically, when the locking pin 52 abuts against the locking hole 211, the rotation of the input rod 22 can be restricted, and this state is the locked state. When the disconnected state is required, the pin handle 523 can be pulled so that the pin handle 523 can overcome the force of the locking spring 53 and slide in the long hole 512. When the cylindrical section 522 slides into the long hole 512, the locking pin 52 is now separated from the locking hole 211, and the locking pin 52 is rotated so that the long hole section 521 and the long hole 512 are staggered. Then, the hand is released, and the end of the long hole section 521 abuts against the closed end 511. The locking pin 52 remains in the disconnected state, and in this state, the input rod 22 can rotate normally.

[0050] The flip assembly 4 is arranged on the flip bracket 3. The flip assembly 4 includes a support arm 41 and an arc-shaped flip frame 42 arranged on both sides of the support arm 41. The ends of the arc-shaped flip frame 42 are provided with a flip arm 43. An ear shaft 44 is provided at the center position of the flip arm 43. The ear shaft 44 is rotatably arranged in the ear shaft support hole 33.

[0051] The ear shaft support hole 33 cooperates with the ear shaft, and the ear shaft can rotate freely in the ear shaft support hole 33. In order to enable the worm reducer 2 to control the flipping of the flip assembly 4, a polygonal flip hole is provided at the center of the ear shaft 44, and a polygonal through hole 23 is provided at the center of the output shaft of the gear box 21; the polygonal pin 24 passes through the polygonal through hole 23 and the polygonal flip hole and is connected to the nut. Therefore, the polygonal pin 24 plays a transmission role and can transmit the power of the output shaft of the gear box 21 to the flip arm 43. If the polygonal pin 24 is pulled out, the power between the gear box 21 and the flip arm 43 is separated. The polygonal through hole 23, the polygonal flip hole, and the polygonal pin 24 in this embodiment are all hexagonal.

[0052] like Figures 13 to 15 As shown, the flip arm 43 is connected to the output end of the worm gear reducer 2; the two ends of the support arm 41 are respectively provided with a fixing plate 45 with a pin and a rotatable locking block 46; when in use, one end of the oil drum abuts against the fixing plate 45, and the other end of the oil drum is fixed by the locking block 46. The two ends of the oil drum are directly fixed to the support arm 41 through the fixing plate 45 and the locking block 46. The arc-shaped flip frame 42 and the support arm 41 form a clamp with the opening upward, and the arc-shaped flip frames 42 on both sides protect and limit the oil drum.

[0053] The fixing plate 45 is directly fixed on the support arm 41. At the other end of the support arm 41, a support through hole 411 is provided on the support arm 41, a screw 461 is provided in the support through hole 411, one end of the locking block 46 is fixed on one end of the screw 461, and the other end of the screw 461 is threadedly connected to a tightening hand wheel 462; the locking block 46 can be locked by turning the tightening hand wheel 462.

[0054] The working principle of this embodiment is as follows: first, the oil drum is lifted with the oil drum lifting device so that the bottom of the oil drum is at the same height as the fixing plate 45 at one end of the support arm 41, the bottom of the oil drum is butted against the pins on the fixing plate 45, and then the locking block 46 is rotated so that the locking block 46 is butted against the inner side of the flange at the top of the oil drum, and then the locking block 46 is tightened to ensure that the oil drum is fixedly mounted on the support arm 41 by the fixing block and the locking block 46; Then, the polygonal pin 24 is passed through the polygonal through hole 23 and the polygonal flip hole and connected with the nut, so that the power of the output shaft of the gear box 21 can be transmitted to the flip bracket 3.

[0055] When the oil drum needs to be turned over, the spring pin 5 can be unlocked, and then the hand wheel is turned to rotate the input rod 22, thereby rotating the output shaft of the gear box 21, thereby rotating the turning bracket 3, and the oil can be poured out of the oil drum.

[0056] If the input rod 22 reaches the maximum stroke, the polygonal pin 24 can be pulled out from the polygonal through hole 23 and the polygonal flip hole; the flip angle of the oil barrel is manually rotated, and then the polygonal pin 24 is inserted into the polygonal through hole 23 and the polygonal flip hole again. Then, the tilt angle of the oil barrel is adjusted by rotating the input rod 22 again. In other words, the present application can adjust the angle of the oil barrel in the above manner, so that the oil barrel can be flipped 360 degrees, so that the oil in the oil barrel can be completely poured out.

[0057] Therefore, the present invention cooperates with a flip bracket 3 and a worm gear reducer 2, installs the oil barrel through the flip bracket 3, and then rotates the flip bracket 3 through the worm gear reducer 2 to realize the dumping of the oil barrel, so that the oil barrel can be flipped 360 degrees, so that the oil in the oil barrel can be completely dumped out, reducing oil waste.

The upper end surface of the middle section and the end section of the transport frame 11 is provided with the folded steel plate 14, and the folded edge of the folded steel plate 14 faces upward. The upper end of the long beam at the open end 13 of the transport trolley 1 is provided with a flip bracket 3, and the flip bracket 3 is an isosceles trapezoidal closed frame. The top of the flip bracket 3 is provided with a flip bracket short beam 31, and the top of the flip bracket short beam 31 is provided with a detachable ear shaft support 32. The ear shaft support 32 is a vertical long strip of thick steel plate with a bottom plate. In this embodiment, a 20 mm thick carbon steel plate is used. A circular ear shaft support hole 33 is opened on the upper part of the ear shaft support 32, and the ear shaft support hole 33 is located in the middle position of the ear shaft support 32.

[0060] like Figure 5 and Figure 6As shown, the worm gear reducer 2 is arranged on one side of the flip bracket 3.

Thus, the polygonal pin 24 plays a transmission role and can transmit the power of the output shaft of the gear box 21 to the flip arm 43. The polygonal through hole 23, the polygonal flip hole, and the polygonal pin 24 in this embodiment are all hexagonal.

[0061] In one embodiment, a mounting plate 25 is provided at one end of the input rod 22 close to the gear box 21, and a hand wheel 26 is provided at one end of the input rod 22 away from the gear box 21. A spring pin 5 is provided on the mounting plate 25, and a locking hole 211 cooperating with the spring pin 5 is provided on the gear box 21. The spring pin 5 includes a sleeve 51, in which a locking pin 52 is slidably provided; a locking spring 53 is provided in the sleeve 51 to push the locking pin 52 toward the locking hole.

[0062] like Figures 8 to 12 As shown, the spring pin 5 can be in a locked or disconnected state by pulling and rotating; specifically, when the locking pin 52 abuts against the locking hole 211, the rotation of the input rod 22 can be restricted, and this state is the locked state. When the disconnected state is required, the pin handle 523 can be pulled so that the pin handle 523 can overcome the force of the locking spring 53 and slide in the long hole 512. When the cylindrical section 522 slides into the long hole 512, the locking pin 52 is now separated from the locking hole 211, and the locking pin 52 is rotated so that the long hole section 521 and the long hole 512 are staggered. Then, the hand is released, and the end of the long hole section 521 abuts against the closed end 511.

[0068] The locking structure includes a fixing hole 71 arranged on the fixing link 7 and a fixing bolt 72 threadedly matched with the fixing hole 71 . A locking through hole 414 corresponding to the fixing hole 71 is arranged on the support arm 41 . The fixing bolt 72 passes through the locking through hole 414 and is threadedly connected to the fixing hole 71 .

[0069] In this embodiment, the first through hole 82 is provided on the first slider 8, the support through hole 411 is in the shape of a long strip, the support through hole 411 is provided at the bottom of the first slide groove 412, the width of the support through hole 411 is smaller than the width of the first slide groove 412, and the support through hole 411 is provided along the length direction of the first slide groove 412. The screw rod 461 passes through the support through hole 411, the first slide groove 412, and the first through hole and is connected with the nut, so that when the first slider 8 slides in the first slide groove 412, the screw rod 461 can also slide in the support through hole 411.

[0070] A connecting long hole 415 is provided between the first sliding groove 412 and the second sliding groove 413, and the fixing connecting rod 7 is slidably provided in the connecting long hole 415. A locking through hole is provided on the side wall of the connecting long hole 415.

[0071] The working principle of this embodiment is as follows: first, the oil drum is lifted with the oil drum lifting device so that the bottom of the oil drum is at the same height as the fixing plate 45 at one end of the support arm 41, the bottom of the oil drum is butted against the pins on the fixing plate 45, and then the locking block 46 is rotated so that the locking block 46 is butted against the inner side of the flange at the top of the oil drum, and then the locking block 46 is tightened to ensure that the oil drum is fixedly mounted on the support arm 41 by the fixing block and the locking block 46; Then, the polygonal pin 24 is passed through the polygonal through hole 23 and the polygonal flip hole and connected with the nut, so that the power of the output shaft of the gear box 21 can be transmitted to the flip bracket 3.

[0072] When the oil drum needs to be turned over, the spring pin 5 can be unlocked, and then the hand wheel is turned to rotate the input rod 22, thereby rotating the output shaft of the gear box 21, thereby rotating the turning bracket 3, and the oil can be poured out of the oil drum.

[0073] If the input rod 22 reaches the maximum stroke, the polygonal pin 24 can be pulled out from the polygonal perforation 23 and the polygonal flip hole; the flip angle of the oil barrel is manually rotated, and then the polygonal pin 24 is inserted into the polygonal perforation 23 and the polygonal flip hole again. Then, the tilt angle of the oil barrel is adjusted by rotating the input rod 22 again. In other words, the present application can adjust the angle of the oil barrel in the above manner, so that the oil barrel can be flipped 360 degrees, so that the oil in the oil barrel can be completely poured out, reducing oil waste.

[0074] Therefore, the present invention cooperates with a flip bracket 3 and a worm gear reducer 2, installs the oil barrel through the flip bracket 3, and then rotates the flip bracket 3 through the worm gear reducer 2 to realize the dumping of the oil barrel, so that the oil barrel can be flipped 360 degrees, so that the oil in the oil barrel can be completely dumped out, reducing oil waste.

[0075] In addition, during normal use, the fixing bolt 72 passes through the locking through hole and is connected to the fixing hole 71, so that the fixing connecting rod 7 is locked in the connecting long hole 415; at this time, the oil is poured out from the oil barrel as in the steps of Example 1.

[0076] When the oil barrel is tilted to the maximum angle, and the oil outlet of the oil barrel is tilted downward, the oil has a certain adhesion and will adhere to the side wall of the oil barrel, so that the oil on the inner wall of the oil barrel falls along the inner wall as quickly as possible.

[0077] The fixing bolt 72 is taken out from the locking through hole and the fixing hole 71, so that the fixing connecting rod 7 can slide in the connecting long hole 415; since most of the oil in the oil barrel has been poured out at this time, the oil barrel can be pulled manually, so that the first slide block 8 slides in the first slide groove 412, and the second slide block 6 slides in the second slide groove 413, so that when the oil barrel moves, the inertia of the oil itself is used to make the oil flow downward as quickly as possible, so that the oil in the oil barrel can flow out more fully, further reducing the waste of oil in the oil barrel. When the new oil drum is reinstalled next time, the fixing bolt 72 is passed through the locking through hole and connected to the fixing hole 71 again, so that the fixing connecting rod 7 is locked in the connecting long hole 415, and the steps in the installation embodiment 1 are followed to install the oil drum on the flip bracket 3.
