Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste oil bucket residual cleaning, in particular to a suspended waste oil bucket residual cleaning device. BACKGROUND

[0002] In the field of industrial production and mechanical maintenance, waste oil treatment has always been a key link related to safety production and environmental protection. The traditional residual cleaning method relies on manual carrying and tilting, which is not only time-consuming and laborious, but also easy to cause waste oil dripping due to improper operation, resulting in soil and water pollution. At the same time, there are safety hazards such as workers slipping and being splashed by waste oil. Therefore, the suspended waste oil bucket residual cleaning device is born at the right moment. The device is fixed on the top of the workshop or the gantry through an adjustable suspension bracket, and uses a hydraulic or electric drive system to realize the lifting, overturning and angle control of the waste oil bucket. The waste oil bucket is placed in a special clamp and locked. The oil bucket is raised to the appropriate height by operating the control panel, and then the overturning angle is adjusted by a rocker or a button. The residual oil in the barrel flows into the oil receiving container through the bottom oil outlet.

[0003] However, in the actual operation of the existing waste oil bucket residual cleaning device, when processing viscous media such as long-term stored waste engine oil and gear oil, oil stains will adhere to the inner wall of the oil barrel. Even if the barrel is turned over to 180 degrees, the viscous waste oil in the barrel can hardly flow out smoothly relying on gravity, increasing the workload of subsequent cleaning and processing. In the process of fixing the oil barrel, the operator needs to manually lock and fix the upper, middle and lower parts of the oil barrel several times, which is a relatively cumbersome operation step. In addition, uneven locking may cause the barrel to shake during overturning, which poses a safety hazard.

[0004] In view of the above problems, it is urgent to make innovative design on the basis of the original. SUMMARY

[0010] Preferably, a first limiting block corresponding to the transmission slot is fixedly arranged on the surface of the first driving shaft, a second limiting block corresponding to the limiting slot is fixedly arranged on the surface of the rotating shaft, and the limiting slot is designed in an L shape.

[0012] Preferably, a ratchet set is arranged at the top end of the transmission shaft, and a driving bevel gear is connected to the top end of the transmission shaft through the ratchet set.

[0013] Preferably, a connecting block is provided at the end of the second drive shaft for limiting sliding, and the tail end of the drive shaft is connected to the second drive shaft through the connecting block.

[0014] Preferably, a rotating plate is fixed at the bottom of the spring holder, and an electric push rod is provided inside the striking seat, with the extended end of the electric push rod slidably connected to the rotating plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the setting of a striking seat, a second drive shaft, a clamping block, and a striking assembly, assists in oil discharge when the waste oil drum rotates and is being emptied. The striking assembly is used to evenly strike the drum wall, and the continuous vibration breaks the adhesion between the viscous waste oil and the drum wall, accelerating the shedding of residual oil. When the waste oil drum is rotating for emptying, the second drive shaft drives the energy storage spring to rotate through the transmission shaft to store energy. After the drum body completes a 180° rotation, the connection between the transmission shaft and the second drive shaft is disconnected, and the stored energy storage spring releases its power. Through the drive bevel gear, it drives the transmission bevel gear to rotate, causing multiple sets of striking columns to push the striking plate, which drives the striking block to reciprocate and continuously strike the wall of the waste oil drum, thereby improving the oil discharge efficiency, reducing residual oil, and reducing the intensity of operation. 2. This invention, through its movable clamping plate, first drive shaft, transmission link, locking rod, movable telescopic rod, and limiting clamping assembly, efficiently completes the clamping of waste oil drums, achieving fully automatic clamping and fixing without the need for repeated manual locking, reducing operational steps. The first drive shaft drives the limiting clamping assembly, which in turn rotates the transmission link, causing the clamping block to clamp the waste oil drum. As the first drive shaft continues to rotate, the connection between the first drive shaft and the rotating shaft is released. The first drive shaft pulls the rotating shaft through the screw rod, causing the transmission link and the clamping seat to slide on the side wall of the lifting seat. Under the pressure of the limiting rod, the locking rod moves relative to the oil drum, and its bottom inclined support block enters the bottom of the drum, lifting the oil drum so that its top engages with the locking rod's top buckle. The support block and buckle cooperate to form a fixed upper and lower structure, preventing the oil drum from shaking, improving safety, and reducing manual labor intensity.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-10 This invention provides a technical solution: a suspended waste oil drum emptying and cleaning device, including a suspension frame 1 and a lifting seat 101. A clamping seat 2 is slidably installed on the side wall of the lifting seat 101, which can be adjusted in position with subsequent structures. A transmission connecting rod 4 is rotatably installed on the side wall of the clamping seat 2. A first drive shaft 3 is rotatably installed at the center position inside the lifting seat 101. A limit clamping component is provided at the end of the first drive shaft 3. Two movable clamping plates 201 are slidably installed on the side wall of the clamping seat 2. A movable groove 202 is opened on the side wall of the movable clamping plate 201. A movable telescopic rod 501 is slidably installed inside the movable groove 202. A locking rod 5 is fixed in the middle of the movable telescopic rod 501. A striking seat 6 is fixed on the side wall of the clamping seat 2. A striking component is provided inside the striking seat 6. A second drive shaft 7 is rotatably installed inside the clamping seat 2. A clamping block 701 is connected to the end of the second drive shaft 7. The limiting clamping assembly includes a rotating shaft 301 rotatably mounted at the center of the lifting seat 101, and a movable sleeve 302 that limits sliding at the end of the first drive shaft 3. The movable sleeve 302 has a transmission groove 304 at its end and a limiting groove 303 on its surface. A helical rod 305 is fixed at the end of the first drive shaft 3 and is threadedly connected to the inside of the rotating shaft 301. The assembly also includes a limiting rod 102 slidably mounted on the side wall of the lifting seat 101. The movable groove 202 provides sliding space for the movable telescopic rod 501. The locking rod 5 at the end of the movable telescopic rod 501 can further fix the oil drum vertically during clamping. The cooperation between the support block and the buckle forms a double fixation, enhancing the stability of the oil drum and avoiding the risk of falling off when the contents are poured out.

[0020] In one embodiment of the present invention, the movable groove 202 is designed with an arc shape, the end of the limiting rod 102 is located inside the movable groove 202, and the two ends of the movable telescopic rod 501 are respectively located inside the two movable grooves 202. The arc-shaped movable groove 202 provides a moving path for the subsequent locking rod 5 to follow the rotation of the waste oil drum. The end of the limiting rod 102 is located inside the movable groove 202 and presses against the movable telescopic rod 501, so that the subsequent locking rod 5 can move relative to the waste oil drum, accurately completing the operation of the support block entering the bottom and the top buckle locking, enhancing the stability of the waste oil drum when it is dumped and overturned, and providing a solid guarantee for efficient and safe operation.

[0021] In one embodiment of the present invention, a buckle is provided at the top of the locking rod 5, and an inclined support block is provided at the bottom of the locking rod 5. The buckle at the top adopts an arc-shaped design that adapts to the mouth of the oil drum. When the waste oil drum is lifted, it can accurately engage with the edge of the mouth of the drum, forming a firm constraint from the top, preventing the drum body from falling off due to gravity when it is overturned and spilled. The inclined support block at the bottom utilizes a sloping structure, which can slide naturally into the bottom of the drum along the drum wall when the locking rod 5 moves relative to the oil drum. The upward lifting force is generated by the inclined angle, which lifts the oil drum smoothly, making the fixing process more efficient and reliable.

[0022] In one embodiment of the present invention, a transmission link 4 is connected to the end of the rotating shaft 301. The two ends of the transmission link 4 are respectively connected to two movable clamping plates 201. When the rotating shaft 301 rotates under power drive, its torque can be efficiently transmitted to the two movable clamping plates 201 through the transmission link 4. Since the two ends of the transmission link 4 are respectively connected to the movable clamping plates 201, the rotational motion of the rotating shaft 301 can be converted into the opposite or opposite motion of the two movable clamping plates 201, thereby realizing the clamping and release of the waste oil drum and improving the clamping accuracy and operational reliability of the device.

[0023] In one embodiment of the present invention, a first limiting block corresponding to the transmission groove 304 is fixed on the surface of the first drive shaft 3, and a second limiting block corresponding to the limiting groove 303 is fixed on the surface of the rotating shaft 301. The limiting groove 303 is L-shaped. When the device is initially started, the first limiting block is embedded in the transmission groove 304, and the second limiting block is in the transverse section of the L-shaped limiting groove 303. At this time, the rotational force of the first drive shaft 3 can be directly transmitted to the rotating shaft 301 through the movable sleeve 302 to achieve synchronous rotation of the two, ensuring that the transmission linkage 4 can efficiently drive the movable clamping plate 201 to complete the initial clamping action. When the clamping block 701 is in contact with the oil drum and the rotation of the rotating shaft 301 is obstructed, the continuously running first drive shaft 3 will increase the system torque, pushing the second limiting block to slide along the transverse section of the L-shaped limiting groove 303 to the corner and enter the longitudinal section. During the sliding process, the movable sleeve 302 moves, causing the first limiting block to disengage from the transmission groove 304 and releasing the rotational linkage between the first drive shaft 3 and the rotating shaft 301.

[0024] In one embodiment of the present invention, the striking assembly includes a spring holder 601 rotatably mounted inside the striking base 6, a drive shaft 603 rotatably mounted inside the spring holder 601, an energy-storing spring 602 fixed to the side wall of the drive shaft 603, the energy-storing spring 602 being connected to the side wall of the drive shaft 603 inside the spring holder 601, a drive bevel gear 604 connected to the top end of the drive shaft 603, and a second drive shaft 7 connected to the tail end of the drive shaft 603. It also includes a drive bevel gear 605 rotatably mounted inside the striking base 6. The transmission bevel gear 605, which meshes with the drive bevel gear 604, has multiple sets of striking columns 606 fixed to its side wall. It also includes a striking block 8 rotatably mounted at the bottom of the striking seat 6. A striking plate 801 is fixed to the top of the striking block 8. The striking plate 801 is located in the gap between the multiple sets of striking columns 606. When the striking column 606 rotates, it will continuously push the striking plate 801, causing the striking block 8 at the bottom to reciprocate, forming a uniform and continuous striking on the wall of the waste oil drum. This effectively breaks the adhesion between the viscous waste oil and the drum wall, accelerates the shedding of residual oil, and greatly improves the oil discharge efficiency.

[0025] In one embodiment of the present invention, a ratchet assembly is provided at the top of the transmission shaft 603, and the top of the transmission shaft 603 is connected to the drive bevel gear 604 through the ratchet assembly. When the second drive shaft 7 drives the transmission shaft 603 to rotate, the energy storage spring 602 contracts synchronously to store energy. At this time, since the transmission shaft 603 and the drive bevel gear 604 are connected through the ratchet assembly, the drive bevel gear 604 remains stationary to ensure energy storage. When the transmission shaft 603 is unrestrained and the energy storage spring 602 releases energy to drive its rotation, the ratchet assembly automatically engages, and the drive bevel gear 604 is linked with the engaged transmission bevel gear 605, causing the multiple sets of striking columns 606 on the side wall of the transmission bevel gear 605 to rotate synchronously, triggering the striking action, thereby improving the energy utilization efficiency and operational stability of the device.

[0026] In one embodiment of the present invention, a connecting block is provided at the end of the second drive shaft 7 for limiting sliding. The tail end of the transmission shaft 603 is connected to the second drive shaft 7 through the connecting block. The side wall of the connecting block is designed to be inclined. The clamping seat 2 is provided with a squeezing block corresponding to the connecting block. When the waste oil drum rotates with the second drive shaft 7 to the 180° dumping position, the squeezing block inside the clamping seat 2 contacts the inclined side wall of the connecting block, pushes the connecting block into the interior of the second drive shaft 7, and disconnects it from the transmission shaft 603.

[0027] In one embodiment of the present invention, a rotating plate is fixed to the bottom of the spring holder 601, and an electric push rod is provided inside the striking seat 6. The extended end of the electric push rod is slidably connected to the rotating plate. By extending and retracting the electric push rod, the rotating plate is pushed to drive the spring holder 601 to rotate as a whole. When the device processes oil drums of different sizes, the controller can adjust the extension length of the electric push rod according to the oil drum parameters fed back by the sensor, so that the spring holder 601 rotates at a corresponding angle, thereby expanding the applicability of the device.

[0028] Working Principle: When using this suspended waste oil drum emptying and cleaning device, the operator first pushes the suspension frame 1 to initially align the two clamping blocks 701 with the waste oil drum. Then, the motor is started to drive the first drive shaft 3. Since the first limiting block installed on the surface of the first drive shaft 3 is located in the transmission groove 304, and the second limiting block installed on the surface of the rotating shaft 301 is located in the limiting groove 303, the first drive shaft 3 rotates simultaneously, driving the rotating shaft 301 synchronously through the moving sleeve 302. The rotating shaft 301 then drives the transmission connecting rod 4 to rotate, pulling the two moving clamping plates 201 closer together, gradually reducing the distance between them and the waste oil drum. When the clamping blocks 701 are completely in contact with and clamp the waste oil drum, the first drive shaft 3 continues to rotate. At this time, the rotating shaft 301 is restricted in its rotation due to the reverse force of the waste oil drum, and the torque gradually increases. The second limiting block is then restricted in the limiting groove 303. Guided, slide to the other end of the limiting groove 303, push the moving sleeve 302 away from the first limiting block, and release the connection between the first drive shaft 3 and the rotating shaft 301. Since the spiral rod 305 fixed at the end of the first drive shaft 3 is threadedly connected to the inside of the rotating shaft 301, the continuous rotation of the first drive shaft 3 will drive the rotating shaft 301 to retract and move inward. The rotating shaft 301 drives the transmission connecting rod 4 and the clamping seat 2 to move synchronously into the lifting seat 101. During this process, the end of the limiting rod 102 is located in the moving groove 202, pressing against the moving telescopic rod 501, causing the locking rod 5 to move relative to the waste oil drum. The bottom end of the locking rod 5 tilts and enters the bottom of the waste oil drum, lifting the waste oil drum so that its top is locked into the top buckle of the locking rod 5. The block and the buckle cooperate to form an upper and lower fixation, preventing the waste oil drum from shaking. The moving groove 202 provides a moving path for the locking rod 5 to follow the rotation of the waste oil drum. As the two movable clamping plates 201 approach each other, the sensor senses the moving distance of the movable clamping plates 201 in real time, and adjusts the extension length of the electric push rod through the controller to drive the spring seat 601 to rotate, thereby adjusting the energy storage intensity of the energy storage spring 602 to ensure that the force of the subsequent striking action matches the characteristics of the oil drum. After the waste oil drum is secured, the motor is started to drive the second drive shaft 7, causing the clamping block 701 to rotate and gradually tilt the waste oil drum for emptying. Simultaneously, the drive shaft 603 connected to its end rotates, pulling the energy storage spring 602 to gradually retract, storing kinetic energy for subsequent striking. Since the drive shaft 603 is connected to the drive bevel gear 604 via a ratchet assembly, the drive bevel gear 604 remains stationary during the energy storage phase of the drive shaft 603's rotation. After the waste oil drum completes a 180° tilt, the limiting sliding connecting block at the end of the second drive shaft 7 is moved. The clamping plate 201 is squeezed and retracts into the second drive shaft 7, releasing the connection between the second drive shaft 7 and the transmission shaft 603. The transmission shaft 603 loses its limit and pulls the energy storage spring 602 to quickly release the stored energy, driving the transmission shaft 603 to rotate. The transmission shaft 603 drives the drive bevel gear 604 to rotate. The drive bevel gear 604 meshes with the transmission bevel gear 605. The multiple sets of striking columns 606 fixed on the side wall of the transmission bevel gear 605 rotate accordingly, continuously pushing the striking plate 801, which in turn drives the striking block 8 to generate high-frequency reciprocating motion, forming a uniform impact on the wall of the waste oil drum and improving the oil discharge efficiency.
