Description

Technical Field

[0001] The utility model relates to the technical field of waste lubricating oil transportation, in particular to a conveying device for recycling waste lubricating oil. Background Art

[0002] Waste lubricating oil refers to lubricating oil that has become black in color, increased in viscosity, or gradually deteriorated to produce organic acids, colloids and asphalt-like substances due to the mixing of water, dust, other miscellaneous oils and metal powders produced by wear of machine parts during use. If these waste oils are discarded directly, they will cause serious pollution to the environment, including water and soil pollution, and the decline of air quality. When waste oil needs to be transported to a distant location or for temporary storage, it is usually loaded into special containers, such as oil drums, oil tanks, etc., and transported by conveyor. The conveying device is mainly used to transport waste oil from one place to another for subsequent treatment and regeneration. The use of conveying devices can reduce the cost of manual handling and transportation.

[0003] The existing Chinese patent with announcement number CN220375482U discloses a lubricating oil barrel conveying device, including a bracket and an extension plate movably connected to the bracket, the cross-sectional view of the bracket is "L" shaped, a first roller is arranged on one side of the bottom of the bracket, and a supporting leg is arranged on the other side of the bottom of the bracket, one end of the extension plate is movably connected to the bracket, and a second roller is arranged at the lower part of the other end of the extension plate, and a fixing buckle is arranged at the bottom of the extension plate and the fixing buckle can be clamped with the supporting leg.

[0004] Although the above scheme can transport oil drums containing waste lubricating oil, the device lacks the ability to fix the oil drums during transportation. When the ground is uneven, the oil drums can easily fall. At the same time, there is a lack of buffering function during transportation, which increases the risk of damage to the oil drums during transportation. Therefore, it does not meet existing needs. In this regard, we propose a conveying device for recycling waste lubricating oil. Utility Model Content

[0005] The utility model aims to provide a conveying device for recycling waste lubricating oil, so as to solve the problems that the conveying device proposed in the above background technology lacks the fixation of the waste lubricating oil barrel, which makes it easy to fall and pollute the environment, and lacks the buffer, which makes the waste lubricating oil barrel easy to be damaged.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a conveying device for recycling waste lubricating oil, comprising a base, universal wheels are installed at the four corners of the lower end of the base, and a handle is provided on one side of the upper end of the base;

[0007] It also includes a fixed seat, which is arranged at the upper end of the base, a buffer plate is arranged above the base, and the buffer plate is slidably matched with the fixed seat, a first transmission cavity is opened inside the fixed seat, and two double-threaded transmission rods are rotatably arranged inside the first transmission cavity, the double-threaded transmission rods are connected by a connecting shaft, and the connecting shaft is fixedly connected to the double-threaded transmission rods;

[0008] It also includes second transmission cavities, which are opened on both sides of the base, and each side has three second transmission cavities that are evenly distributed, and the inside of each second transmission cavity is bonded and fixed with a guide rod.

[0009] Preferably, sliders are provided on both sides of the second transmission cavity, and the sliders are slidably matched with the second transmission cavity, and the guide rod passes through the sliders, and the guide rod is slidably matched with the sliders.

[0010] Preferably, buffer springs are sleeved on both sides of the exterior of the guide rod, one end of the buffer spring is connected to the slider, and the other end of the buffer spring is connected to the second transmission chamber.

[0011] Preferably, the slider and the buffer plate are connected via a connecting block, and the connecting block is rotatably connected to the slider and the buffer plate.

[0012] Preferably, both sides of the exterior of the double-threaded transmission rod are threadedly connected with clamping blocks.

[0013] Preferably, three equidistantly distributed dampers are arranged inside the base, and the upper ends of the dampers are all provided with connecting columns, and the upper ends of the connecting columns are all adhered and fixed to the buffer plate.

[0014] Preferably, a rotating shaft is provided at one end of one of the double-threaded transmission rods, one end of the rotating shaft extends to the outside of the first transmission cavity, and the rotating shaft is rotatably matched with the first transmission cavity, and a handwheel is installed at one end of the rotating shaft located outside the first transmission cavity.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model has a fixing seat installed on the upper end of the base. After the oil drum is placed on the buffer plate, the hand wheel can be turned, and the hand wheel will drive the two double-threaded transmission rods to rotate synchronously. The double-threaded transmission rods will drive the clamping blocks to move horizontally toward each other, so that the oil drum can be clamped and fixed by the clamping blocks moving toward each other. The clamping of the clamping blocks can ensure that the oil drum will not slide or tip over during transportation, greatly improving the safety and stability of the operation. The operation process is simple and convenient, and the fixation can be completed by simply turning the hand wheel, which is convenient to use.

[0017] 2. The utility model has three equidistantly distributed second transmission chambers on both sides of the base. When the oil drum vibrates during transportation, the vibration will cause the buffer plate to move up and down. The buffer plate will make the slider slide on the guide rod through the connecting block, thereby squeezing the buffer spring. The slider can be buffered by the buffer spring, so the vibration amplitude of the buffer plate can be reduced. The sliding friction between the slider and the second transmission chamber and the guide rod will consume the energy of the vibration input, thereby improving the buffering effect and avoiding damage to the oil drum during transportation.

[0018] 3. The utility model arranges three dampers at equal intervals inside the base. When the oil drum is subjected to external impact or vibration on the base, the buffer plate will produce a certain displacement. At this time, the three dampers arranged at equal intervals will respond quickly and effectively suppress and absorb the displacement of the buffer plate through the damping mechanism inside. This buffering effect can effectively reduce the impact force on the oil drum and prevent the oil drum from being broken due to violent shaking. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] When in use, place the waste oil barrel of lubricating oil on the buffer plate 5, between the two clamping blocks 11, turn the hand wheel 10, drive the double-threaded transmission rod 7 to rotate through the rotating shaft 9, and then make the two double-threaded transmission rods 7 rotate synchronously through the connecting shaft 8, drive the clamping block 11 to move relative or opposite in the first transmission cavity 6, clamp and fix the oil barrel, when the base 1 moves, the vibration of the oil barrel causes the buffer plate 5 to move up and down, and the buffer plate 5 suppresses and absorbs the displacement through the damper 12, and at the same time drives the connecting block 18 to make the slider 17 slide on the guide rod 15, and the slider 17 squeezes or stretches the buffer spring 16 for buffering, thereby reducing the movement amplitude of the buffer plate 5, and the friction between the slider 17 and the guide rod 15 and the second transmission cavity 14 consumes the vibration energy, further reduces the vibration amplitude, and avoids damage to the oil barrel.

[0029] See also Figure 4 Slide blocks 17 are provided on both sides of the second transmission cavity 14, and the slide blocks 17 are slidably matched with the second transmission cavity 14. The guide rod 15 passes through the slide blocks 17, and the guide rod 15 is slidably matched with the slide blocks 17. The guide rod 15 can ensure the stability of the slide blocks 17 when moving, avoid their deviation, and ensure the accuracy of the buffering process;

[0030] See also Figure 4 , buffer springs 16 are sleeved on both sides of the outer side of the guide rod 15, one end of the buffer spring 16 is connected to the slider 17, and the other end of the buffer spring 16 is connected to the second transmission chamber 14. When the slider 17 is vibrated, the buffer spring 16 can provide elastic buffering force to effectively reduce the impact of the vibration on the oil drum;

[0031] See also Figure 2 and Figure 3The slider 17 and the buffer plate 5 are connected by a connecting block 18, and the connecting block 18 is rotatably matched with the slider 17 and the buffer plate 5, and the connecting block 18 can ensure the connection stability between the buffer plate 5 and the slider 17;

[0032] See also Figure 1 , Figure 2 and Figure 3 The two sides of the double-threaded transmission rod 7 are threadedly connected with clamping blocks 11. By rotating the double-threaded transmission rod 7, the clamping blocks 11 on both sides can be driven to move toward or oppositely at the same time, thereby realizing the rapid clamping or release of the oil drum;

[0033] See also Figure 3 Three equidistantly distributed dampers 12 are arranged inside the base 1, and the upper ends of the dampers 12 are all provided with connecting columns 13, and the upper ends of the connecting columns 13 are all adhered and fixed to the buffer plate 5.

By rotating the hand wheel 10, the rotating shaft 9 and the double-threaded transmission rod 7 can be easily driven to rotate, thereby realizing the clamping operation of the oil drum, and the operation is simple and quick.

[0035] Working principle: When in use, place the waste oil barrel of lubricating oil on the upper end of the buffer plate 5 so that the oil barrel is located between the two clamping blocks 11. At this time, turn the hand wheel 10, the hand wheel 10 will drive the rotating shaft 9 to rotate, and the rotating shaft 9 will drive one of the double-threaded transmission rods 7 to rotate synchronously. The double-threaded transmission rod 7 can make the other double-threaded transmission rod 7 rotate synchronously under the connection of the connecting shaft 8, and the double-threaded transmission rod 7 will drive the clamping block 11 to rotate synchronously when it rotates. Since the clamping blocks 11 are slidably matched with the first transmission cavity 6, the clamping blocks 11 will be axially limited, and the two clamping blocks 11 on the double-threaded transmission rod 7 will move horizontally in opposite or opposite directions, so that the oil barrel can be clamped and fixed, thereby ensuring that the oil barrel will not slide or tip over during transportation, greatly improving the safety and stability of the operation. The operator can push the base 1 by grabbing the handle 2, and the base 1 can be moved under the rolling of the universal wheel 3. When the base 1 moves It may cause the oil drum to vibrate up and down. When the oil drum vibrates, the buffer plate 5 will move up and down synchronously. The fixed seat 4 and the buffer plate 5 slide in cooperation, which can limit the buffer plate 5 to a certain extent and prevent the buffer plate 5 from shaking. When the buffer plate 5 moves up and down, the damper 12 can effectively suppress and absorb its displacement, effectively reducing the impact force on the oil drum. At the same time, the buffer plate 5 will make the slider 17 slide on the guide rod 15 through the connecting block 18. The guide rod 15 will limit and guide the slider 17 to prevent the slider 17 from shifting. When the slider 17 slides, it will squeeze and stretch the buffer spring 16. The elastic action of the buffer spring 16 can buffer the buffer plate 5, thereby reducing the movement amplitude of the buffer plate 5. At the same time, the friction force generated by the sliding between the slider 17 and the guide rod 15 and the second transmission cavity 14 can consume the energy of the vibration input, further reduce the vibration amplitude of the buffer plate 5, and avoid damage to the oil drum during transportation.
