Description

Technical Field

[0001] This utility model relates to the field of oil drum transportation technology, specifically to a lifting device for oil drums. Background Technology

[0002] Currently, many factory workshops require the use of cylindrical sheet metal oil drums to store oily materials. During the transportation of these oil drums, hoisting equipment is often used. In existing technology, the oil drums are usually placed on pallets, and the pallets are lifted by hoisting equipment to achieve the purpose of lifting the oil drums. However, the pallets are prone to shaking during the hoisting process, which can cause the oil drums placed on the pallets to be affected by the shaking and tip over to one side, resulting in the oil drums falling from a height and creating safety hazards, as well as causing oil leakage and waste. Therefore, it is necessary to install a fixing mechanism on the pallet to secure the oil drums.

[0003] The utility model with authorization announcement number CN221253634U provides a mortar hoisting device. The device uses a drive component to move two first limiting plates, which fix one side of the mortar bucket. An adjustment component drives two corresponding transmission rods to rotate, which allows multiple second limiting plates to fix the other two sides of the mortar bucket. This solves the problem that when hoisting a mortar bucket, the bucket may tip over due to the swaying of the hoist, resulting in resource waste.

[0004] The bucket fixing mechanism used in the aforementioned patent requires operators to operate the drive mechanism and adjustment components sequentially to restrict the bucket's freedom in the horizontal direction. This operation is quite cumbersome, and operators spend a lot of time and energy fixing the bucket, resulting in a decrease in bucket lifting efficiency. In addition, after lifting multiple buckets in succession, the operator's attention will decrease, making it easy for the bucket to not be fixed in place, creating a safety hazard. Summary of the Invention

[0005] The purpose of this invention is to provide a lifting device for grease drums to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, one of the objectives of this utility model is to provide a lifting device for grease drums, including an assembly frame. The assembly frame has a tray inside and a lifting mechanism at the top. The lifting mechanism is used to drive the tray to move vertically. A movable plate is provided on the upper side of the tray. A circular groove is formed at the center of the movable plate. A lifting mechanism is provided on the upper side of the tray. The lifting mechanism is used to drive the movable plate to move vertically. A clamping mechanism is provided on the upper side of the tray. When the grease drum is placed on the upper side of the tray and located inside the circular groove, the clamping mechanism fixes the position of the grease drum on the tray.

[0007] As a further improvement to this technical solution, the clamping mechanism includes a rotating ring disposed on the upper side of the movable plate. Several arc-shaped guide rails are slidably disposed on the outer side of the rotating ring. The arc-shaped guide rails are fixedly disposed on the upper side of the movable plate, and the axis of the arc-shaped guide rails and the rotating ring are on the same straight line as the axis of the circular groove. The movable plate is provided with a rotating assembly for driving the rotating ring to rotate.

[0008] As a further improvement to this technical solution, the clamping mechanism further includes several connecting rods that are arranged in a ring array and hinged to the inner wall of the rotating ring. The other end of each connecting rod is hinged to a clamping rod, and the other end of the clamping rod is located on the upper side of the circular groove. Several clamping rods are arranged in a ring array around the circular groove. A guide sleeve is fitted on the clamping rod, and the guide sleeve is fixedly installed on the upper side of the moving plate.

[0009] As a further improvement to this technical solution, the rotating assembly includes a positioning block rotatably disposed on the side of the movable plate, a threaded rod rotatably disposed on the side wall of the positioning block, a nut threadedly connected to the threaded rod, and the nut rotatably disposed on the upper side of the rotating ring.

[0010] As a further improvement to this technical solution, upright frames are symmetrically fixedly connected to both ends of the upper sidewall of the pallet. Two vertically arranged sliding rods are symmetrically fixedly connected between the inside of the upright frames and the pallet. The movable plate is slidably sleeved on the outside of the four sliding rods. An installation cavity is opened inside the pallet. The lifting mechanism includes a lead screw rotatably disposed on the upper sidewall of the upright frame. The lower end of the lead screw passes through the upper sidewall of the pallet and extends into the installation cavity. A driven bevel gear fixed to the end of the lead screw is disposed inside the installation cavity, and the movable plate is threadedly connected to the two lead screws.

[0011] As a further improvement to this technical solution, the lifting mechanism also includes a transmission shaft disposed in the mounting cavity. Two active bevel gears are coaxially fixedly connected to the transmission shaft, and the two active bevel gears mesh with two driven bevel gears respectively. Two mounting brackets are symmetrically rotatably connected to the transmission shaft near both ends, and the two mounting brackets are fixedly installed on both sides of the support plate respectively.

[0012] As a further improvement to this technical solution, the lifting mechanism includes two main shafts rotatably mounted on the upper side of the assembly frame. One end of each main shaft is equipped with a motor for driving the main shaft to rotate. The motor is fixedly mounted on the assembly frame. Collecting rollers are fixedly mounted on both ends of the main shafts. Steel wire ropes are fixedly connected to the collecting rollers. The lower ends of the four steel wire ropes are respectively fixedly mounted on the upper side of the two upright frames.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This grease drum hoisting device, after placing the grease drum on the upper side of the pallet and positioning it inside the circular groove, allows the operator to start the electric motor, causing its output shaft to drive the transmission shaft to rotate. This causes the two lead screws to rotate synchronously, moving the moving plate vertically upwards. The circular groove then moves to the middle position of the grease drum's side wall, preventing the grease drum from moving horizontally or tipping to one side. This ensures the safety of the grease drum during hoisting and improves the hoisting efficiency.

[0015] 2. This grease drum hoisting device, after placing a grease drum with a diameter smaller than the inner diameter of the circular groove inside the groove, rotates the rotating ring by turning the threaded rod. The rotating ring drives the corresponding clamping rods close to the axis of the circular groove through several connecting rods until one end of each clamping rod contacts the circumferential side wall of the grease drum. This prevents the grease drum from moving horizontally in the circular groove, improves the stability of the grease drum during hoisting, and reduces the possibility of grease leakage due to shaking.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0030] Please see Figures 1-6 As shown, one of the objectives of this embodiment is to provide a lifting device for grease drums, including an assembly frame 1. The assembly frame 1 has a tray 2 inside, and a lifting mechanism 3 is provided on the top of the assembly frame 1. The lifting mechanism 3 is used to drive the tray 2 to move vertically. A movable plate 4 is provided on the upper side of the tray 2. A circular groove 41 is opened at the center of the movable plate 4. A lifting mechanism 5 is provided on the upper side of the tray 2. The lifting mechanism 5 is used to drive the movable plate 4 to move vertically. When the lower side of the tray 2 touches the ground and the movable plate 4 contacts the tray 2, the operator first places the grease drum on the upper side of the tray 2, and makes the bottom end of the grease drum located inside the circular groove 41. Then, the lifting mechanism 5 drives the movable plate 4 to move vertically upward until the circular groove 41 moves to the middle position of the side wall of the grease drum. Then, the lifting mechanism 3 drives the tray 2 and the grease drum to move vertically upward to achieve the purpose of lifting the grease drum. During the lifting of the grease drum, the circular groove 41 on the movable plate 4 restricts the horizontal movement and tipping of the grease drum, thereby improving the safety of the grease drum during the lifting process.

[0031] Reference Figure 2The upper sidewall of the support plate 2 is symmetrically fixedly connected to two ends of the support frame 2. Two vertically arranged sliding rods 22 are symmetrically fixedly connected between the inside of the support frame 21 and the support plate 2. The moving plate 4 is slidably sleeved on the outside of the four sliding rods 22, allowing the moving plate 4 to move only along the axis of the sliding rods 22. An installation cavity 23 is provided inside the support plate 2. The structure of the lifting mechanism 5 is detailed below. The lifting mechanism 5 includes a lead screw 55 rotatably mounted on the upper sidewall of the support frame 21. The lead screw 55 is vertically arranged, and its lower end passes through the upper sidewall of the support plate 2 and extends into the installation cavity 23. A driven bevel gear 54 is fixedly mounted on the end of the lead screw 55 inside the installation cavity 23. The moving plate 4 is threadedly connected to the two lead screws 55. The lifting mechanism 5 also includes a drive shaft 52 located in the installation cavity 23. Two driving bevel gears are coaxially fixedly connected to the drive shaft 52. Gear 53, two driving bevel gears 53 mesh with two driven bevel gears 54 respectively. Two mounting brackets 51 are symmetrically rotatably connected near both ends of the transmission shaft 52. The two mounting brackets 51 are fixedly installed on both sides of the support plate 2. One end of the transmission shaft 52 is equipped with an electric motor for driving the transmission shaft 52 to rotate. The electric motor is fixedly installed on one of the mounting brackets 51. When the operator starts the electric motor and its output shaft drives the transmission shaft 52 to rotate, the transmission shaft 52 drives the two driving bevel gears 53 to rotate. Through the meshing transmission of the driving bevel gears 53 and the driven bevel gears 54, the two driven bevel gears 54 drive the two lead screws 55 to rotate synchronously. Through the threaded connection between the lead screws 55 and the moving plate 4, the moving plate 4 moves upward along the axis of the slide rod 22, so as to restrict the horizontal movement and tilting of the grease drum through the circular groove 41.

[0032] The following details the structure of lifting mechanism 3, referring to... Figure 1 The lifting mechanism 3 includes two main shafts 31 rotatably mounted on the upper side of the assembly frame 1. One end of each main shaft 31 is equipped with a motor 33 for driving the main shaft 31 to rotate. The motor 33 is fixedly mounted on the assembly frame 1. Collecting rollers 32 are fixedly mounted on both ends of the main shaft 31. Steel wire ropes 34 are fixedly connected to the collecting rollers 32. The lower ends of the four steel wire ropes 34 are respectively fixedly mounted on the upper side of the two upright frames 21. After the two motors 33 start synchronously, their output shafts drive the corresponding main shafts 31 to rotate. The rotating main shafts 31 drive the collecting rollers 32 to rotate, so that the collecting rollers 32 wind up the steel wire ropes 34. Then, the four steel wire ropes 34 pull the pallet 2 upward, so that the pallet 2 moves the grease drum placed on its upper side upward, thereby achieving the purpose of hoisting the grease drum to a certain height.

[0033] Grease drums come in various diameters. When the diameter of the grease drum is smaller than the inner diameter of the circular groove 41, there is room for movement within the groove. When the pallet 2 and the grease drum shake during hoisting, the grease drum can easily move horizontally within the groove 41, further exacerbating the shaking and increasing the risk of grease leakage. To address this issue, a clamping mechanism 6 is installed on the upper side of the pallet 2. The clamping mechanism 6 fixes the position of the grease drum on the pallet 2. The structure of the clamping mechanism 6 is detailed below (refer to...). Figure 4 and Figure 5 The clamping mechanism 6 includes a rotating ring 61 disposed on the upper side of the moving plate 4. Several arc-shaped guide rails 62 are slidably disposed on the outer side of the rotating ring 61. The arc-shaped guide rails 62 are fixedly disposed on the upper side of the moving plate 4, and the axes of the arc-shaped guide rails 62 and the rotating ring 61 are on the same straight line as the axis of the circular groove 41. When the rotating ring 61 is subjected to a rotational force, sliding contact occurs between the circumferential sidewall of the rotating ring 61 and the inner arc surfaces of the several arc-shaped guide rails 62. The several arc-shaped guide rails 62 limit... The rotating ring 61 can only rotate around the axis of the circular groove 41. The clamping mechanism 6 also includes several connecting rods 63 arranged in a ring array and hinged to the inner wall of the circumference of the rotating ring 61. The other end of the connecting rod 63 is hinged to a clamping rod 64, and the other end of the clamping rod 64 is located on the upper side of the circular groove 41. Several clamping rods 64 are arranged in a ring array around the circular groove 41. A guide sleeve 65 is sleeved on the clamping rod 64. The guide sleeve 65 is fixedly set on the upper side of the moving plate 4, and the guide sleeve 65 restricts the moving plate 4 to rotate only around the axis of the circular groove 41. The guide sleeve 65 can move along its axis, which intersects with the axis of the circular groove 41. The moving plate 4 is equipped with a rotating assembly 66 for driving the rotating ring 61 to rotate. In the initial state, there is an obtuse angle between the connecting rod 63 and the clamping rod 64. When the operator controls the rotating assembly 66 to rotate the rotating ring 61, the rotating ring 61 drives one end of several connecting rods 63 to rotate. During the rotation of the connecting rods 63, the angle between the connecting rods 63 and the clamping rods 64 gradually expands to 180 degrees. At this time, the other end of several connecting rods 63 pushes the corresponding clamping rods 64 closer to the axis of the circular groove 41 until several clamping rods 64 are in contact with the circumferential side wall of the grease bucket. At this time, several clamping rods 64 clamp and restrict the side wall of the grease bucket, fixing the grease bucket in the circular groove 41. This prevents the grease bucket with a diameter smaller than the outer diameter of the circular groove 41 from moving horizontally in the circular groove 41, reducing the possibility of grease leakage due to shaking.

[0034] The structure of the rotating assembly 66 is described in detail below, with reference to... Figure 6The rotating assembly 66 includes a positioning block 661 rotatably mounted on the upper side of the movable plate 4. A threaded rod 662 is rotatably mounted on the side wall of the positioning block 661. A nut 663 is threadedly connected to the threaded rod 662. A rotating shaft is fixedly mounted at the bottom of the nut 663. The nut 663 is rotatably mounted on the upper side of the rotating ring 61 via the rotating shaft. When the operator turns the threaded rod 662, the nut 663 moves along the axis of the threaded rod 662 through the threaded connection between the threaded rod 662 and the nut 663. The moving nut 663 pushes the rotating ring 61, causing the rotating ring 61 to rotate between several arc-shaped guide rails 62. During the process, the nut 663 rotates relative to the rotating ring 61 via the rotating shaft. The nut 663 drives the positioning block 661 and the threaded rod 662 to rotate synchronously, so that the axial direction of the threaded rod 662 changes with the rotation of the rotating ring 61. This ensures that the moving nut 663 can drive the rotating ring 61 to rotate continuously. The rotating ring 61 drives the clamping rod 64 to move via the connecting rod 63, thereby achieving the purpose of adjusting the distance between the clamping rod 64 and the axis of the circular groove 41 according to the diameter of the grease drum. By making one end of several clamping rods 64 contact the circumferential side wall of the grease drum, the stability of the grease drum during the hoisting process is improved.

[0035] Here, the distance that the nut 663 moves is the distance that the threaded rod 662 drives the nut 663 to move. Because the rotating ring 61 has several connecting rods 63 inside, and the moving rotating ring 61 does not need to rotate at a large angle, it is only necessary to rotate by a small range of angles to expand the included angle between the connecting rod 63 and the clamping rod 64 to 180 degrees. Therefore, the rotating ring 61 does not need to rotate at a large angle here.

[0036] When using this device, the operator first places the grease drum on the upper side of the pallet 2, ensuring that the bottom of the grease drum is inside the circular groove 41. Then, the operator turns the drive shaft 52 to move the moving plate 4 vertically upward until the circular groove 41 moves to the middle position of the side wall of the grease drum. The operator then turns the threaded rod 662 to bring several clamping rods 64 close to the axis of the circular groove 41 until one end of each clamping rod 64 contacts the circumferential side wall of the grease drum, thereby restricting the horizontal movement and tilting of the grease drum to one side. The operator then simultaneously starts the two motors 33, which drive the pallet 2 and the grease drum vertically upward through the four steel wire ropes 34, achieving the purpose of hoisting the grease drum.
