Description

Technical Field

[0001] The present invention relates to the technical field of transfer equipment, and particularly to a transfer device for naphtha. Background Art

[0002] In the production and transportation of chemical products such as naphtha, the transfer of oil drums is a crucial link. However, traditional transfer methods often have many deficiencies, such as the structure of the transfer vehicle frame being unstable, the operation being complex and cumbersome, the transfer efficiency being low, and the safety being insufficient. These problems not only affect production efficiency but also may pose potential safety hazards to operators and the environment.

[0003] Most traditional transfer vehicle frames adopt a simple frame structure. Although they can meet the basic transfer requirements, there is still room for improvement in terms of stability and operation convenience. The lifting device on the top of the vehicle frame is often simply designed and lacks sufficient power support, resulting in the oil drum being prone to shaking or falling off during the lifting process, bringing considerable risks to the transfer.

[0004] In addition, traditional transfer devices also have many inconveniences in the entry and exit of oil drums. When the oil drum is clamped, manual assistance for positioning and adjustment is often required, which not only increases the labor intensity of the operator but also may cause the oil drum to collide or be damaged during the transfer. After the oil drum is lifted, there is a lack of an effective supporting device to prevent it from falling, further increasing the risk of transfer.

[0005] Moreover, traditional transfer devices also have deficiencies in the alignment of oil drums. Due to the lack of precise guiding and positioning devices, the oil drum is prone to deviation when entering the transfer vehicle frame, which not only affects the accuracy of the transfer but also may cause damage to the vehicle frame and the oil drum itself. At the same time, there is a lack of an effective protection device to prevent the oil drum from being collided or squeezed during the transfer. Summary of the Invention

[0006] The present invention relates to a transfer device for naphtha. By adopting a transfer vehicle frame with a "C" - shaped structure, combining the powerful power of a lifting seat plate and a lifting cylinder, and the design of a follower suspension seat and a clamping cylinder, the present invention not only improves the stability and operation convenience of the transfer but also significantly enhances the safety and reliability of the transfer. At the same time, the combined design of a supporting bracket, a buffer rod, and a spring, as well as the alignment frame, provides strong guarantees for the entry, exit, and alignment of the oil drum, making the entire transfer process smoother and more efficient.

[0007] The present invention provides a transfer device for naphtha, specifically including: a transfer vehicle frame; the transfer vehicle frame is in a "C" shape, and a lifting seat plate is encapsulated on the top of the transfer vehicle frame. A lifting cylinder is fixedly installed upward in the middle of the lifting seat plate, and the piston rod of the lifting cylinder passes through the lifting seat plate downward and is fixedly connected to a follow-up hanging seat; a clamping cylinder is fixedly installed in the middle of the bottom plane of the follow-up hanging seat. The clamping cylinder is a double-headed cylinder, and a clamping jaw is fixedly provided at the end of the piston rod of the clamping cylinder; a control box is fixedly hung at the upper end of the back of the transfer vehicle frame, and the front end of the transfer vehicle frame is an open end; on both the left and right sides inside the frame of the transfer vehicle frame, there are symmetrically arranged supporting brackets. The supporting brackets are in a "C" shape, and the upper and lower ends of the supporting brackets are respectively vertically slidably connected to the transfer vehicle frame through vertically arranged buffer rods. The end of the buffer rod is provided with a plug to seal outside the transfer vehicle frame, and a spring is sleeved on the buffer rod to provide an inward thrust for the supporting bracket; at the middle position of the inner end bottom of the transfer vehicle frame, far away from the open end, there is a positioning frame, and the oil barrel being transferred by the clamping jaw is located between the left and right supporting brackets.

[0008] Optionally, universal wheels for movement are provided at the four corners of the bottom of the transfer vehicle frame, and a handle for pulling and moving is provided at the upper position of the back of the transfer vehicle frame.

[0009] Optionally, pulling plates are respectively vertically downward provided at the four corners of the bottom of the follow-up hanging seat. Pulling holes are penetrated through the pulling plates, and the upper ends of the pulling plates are inclined outward and the lower ends are inclined inward.

[0010] Optionally, the clamping jaws of the clamping cylinder have four annular parts centered on the oil barrel, with two on the left and two on the right as a group and connected to the piston rod at the corresponding end. The clamping jaws of the clamping cylinder move inward and clamp at the upper barrel edge of the oil barrel.

[0011] Optionally, a supporting rod for supporting the bottom of the oil barrel is provided at the lower end of the supporting bracket. A pin shaft is vertically provided at the position of the supporting bracket corresponding to the pulling plate. The pin shaft slides in the pulling hole. When the follow-up hanging seat is pushed downward by the lifting cylinder, the pulling plate drives the pin shaft through the pulling hole to move the supporting bracket outward, and the oil barrel can enter and exit the transfer vehicle frame. When the follow-up hanging seat is driven upward by the lifting cylinder, the pulling plate drives the pin shaft through the pulling hole to move the supporting bracket inward, and the supporting rod moves to the bottom of the oil barrel to be clamped and lifted.

[0012] Optionally, clamping blocks are symmetrically arranged on the left and right of the supporting bracket at the position of the supporting rod. One end of the clamping block is an arc surface that fits the outer wall of the oil barrel, and anti-slip strips are provided on the arc surface of the clamping block. When the supporting rod is at the bottom of the oil barrel, the anti-slip strip surface of the clamping block abuts against the oil barrel to prevent the oil barrel from rotating.

[0013] Optionally, a positioning abutting plate corresponding to the outer wall of the oil barrel is vertically provided at the end of the positioning frame. Buffer side columns are respectively fixedly provided at the edges of the left and right ends of the positioning abutting plate. The positioning abutting plate is used to contact the oil barrel and make the transfer vehicle frame and the oil barrel centered.

[0014] Optionally, the piston rod of the lifting cylinder moves downward to drive the follower lifting seat and the clamping cylinder to move downward. The clamping cylinder clamps the oil barrel below through the jaws. The lifting cylinder drives the follower lifting seat and the clamping cylinder to move upward, and the supporting bracket moves inward synchronously. The supporting rod moves to support the oil barrel to prevent it from falling.

[0015] The present invention provides a transfer device for naphtha, which has the following beneficial effects: First of all, the transfer vehicle frame adopts a "C"-shaped structure, which is not only structurally stable but also convenient to operate. The lifting seat plate on the top of the frame is combined with the lifting cylinder, providing powerful power for the lifting of the oil barrel. At the same time, the design of the follower lifting seat and the clamping cylinder enables the oil barrel to be firmly clamped, ensuring that it will not fall off or shake during the transfer process, greatly improving the stability of the transfer.

[0016] Secondly, the linkage design of the supporting bracket, the buffer rod and the spring provides convenience for the entry and exit of the oil barrel. When the oil barrel is clamped, the supporting bracket can slide outward under the action of external force to make room for the oil barrel; when the oil barrel is lifted, the supporting bracket can slide inward under the action of the spring to firmly support the oil barrel and prevent it from falling. This design not only improves the safety of the transfer but also makes the entire transfer process more smooth and efficient.

[0017] In addition, the alignment frame design at the bottom of the inner end of the transfer vehicle frame provides a strong guarantee for the accurate alignment of the oil barrel. The ingenious combination of the alignment backing plate and the buffer side column can not only play a guiding role when the oil barrel enters the vehicle frame but also protect the oil barrel from collision damage during the transfer process. This user-friendly design not only improves the automation level of the transfer but also further enhances the safety and reliability of the transfer.

[0018] In summary, the transfer device for naphtha proposed by the present invention not only has the advantages of stable structure, simple operation and high transfer efficiency, but also significantly improves the safety and reliability of the oil barrel transfer through a series of ingenious designs and innovations. The wide application of this device is expected to bring more convenient and efficient solutions for the production and transportation of chemical products such as naphtha.

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figures 1 to 8 : The present invention provides a transfer device for naphtha, comprising: a transfer vehicle frame 1; the transfer vehicle frame 1 is in a "C" shape, and a lifting seat plate 2 is encapsulated on the top of the transfer vehicle frame 1. A lifting cylinder 3 is fixedly installed upward in the middle of the lifting seat plate 2. The piston rod of the lifting cylinder 3 passes downward through the lifting seat plate 2 and is fixedly connected to a follower lifting seat 5; a clamping cylinder 6 is fixedly installed in the middle of the bottom plane of the follower lifting seat 5. The clamping cylinder 6 is a double-headed cylinder, and a clamping jaw 601 is fixedly provided at the end of the piston rod of the clamping cylinder 6; a control box 4 is fixedly hung on the upper end of the back of the transfer vehicle frame 1, and the front end of the transfer vehicle frame 1 is an open end; on both left and right sides inside the frame of the transfer vehicle frame 1, there are symmetrically arranged supporting brackets 7. The supporting brackets 7 are in a "C" shape. The upper and lower ends of the supporting brackets 7 are respectively vertically slidably connected to the transfer vehicle frame 1 through vertically arranged buffer rods 703. The ends of the buffer rods 703 are provided with plugs blocking outside the transfer vehicle frame 1. A spring 704 is sleeved on the buffer rods 703 to provide an inward thrust for the supporting brackets 7; at the middle position of the bottom of the inner end of the transfer vehicle frame 1, away from the open end, there is an alignment frame 8. The clamping jaw 601 for clamping the transferred oil barrel 9 is located between the left and right supporting brackets 7.

[0025] Among them, at the four corners of the bottom of the transfer vehicle frame 1, there are universal wheels 101 for movement, and at the upper position of the back of the transfer vehicle frame 1, there is a handlebar 102 for pulling and moving.

[0026] Among them, at the four corners of the bottom of the follower lifting seat 5, there are respectively vertically downwardly arranged pulling plates 501. Through holes 502 are formed through the pulling plates 501. The upper ends of the pulling plates 501 are outward and the lower ends are inward in an inclined state.

[0027] Among them, the clamping jaws 601 of the clamping cylinder 6 have four parts in a ring shape centered on the oil barrel 9. Two on the left and two on the right are in a group and are connected to the piston rods at the corresponding ends. The clamping jaws 601 of the clamping cylinder 6 move inward and clamp on the upper barrel edge of the oil barrel 9.

[0028] Among them, at the lower end of the supporting bracket 7, there is a supporting rod 701 for supporting the bottom of the oil barrel 9. At the position corresponding to the pulling plate 501 at the upper end of the supporting bracket 7, there is a pin shaft 702 vertically arranged. The pin shaft 702 is slidably placed in the through hole 502. When the follower lifting seat 5 is pushed downward by the lifting cylinder 3, the pulling plate 501 drives the pin shaft 702 through the through hole 502 to move the supporting bracket 7 outward, and the oil barrel 9 can enter and exit the transfer vehicle frame 1. When the follower lifting seat 5 is driven upward by the lifting cylinder 3, the pulling plate 501 drives the pin shaft 702 through the through hole 502 to move the supporting bracket 7 inward, and the supporting rod 701 moves to the bottom of the clamped and lifted oil barrel 9.

[0029] Among them, clamping blocks 705 are symmetrically arranged on the left and right sides of the supporting bracket 7 at the supporting rod 701. One end of the clamping block 705 is an arc surface that fits the outer wall of the oil barrel 9. Anti-slip strips 7051 are provided on the arc surface of the clamping block 705. When the supporting rod 701 is at the bottom of the oil barrel 9, the anti-slip strip 7051 surface of the clamping block 705 abuts against the oil barrel 9 to prevent the oil barrel 9 from rotating.

[0030] Among them, a positioning abutting plate 801 corresponding to the outer wall of the oil barrel 9 is vertically provided at the end of the positioning frame 8. Buffer side columns 802 are respectively fixed at the edges of the left and right ends of the positioning abutting plate 801. The positioning abutting plate 801 is used to contact the oil barrel 9 and make the transfer vehicle frame 1 and the oil barrel 9 centered.

[0031] Embodiment 2, on the basis of Embodiment 1, the piston rod of the lifting cylinder 3 moves downward to drive the follower suspension seat 5 and the clamping cylinder 6 to move downward. The clamping cylinder 6 clamps the lower oil barrel 9 through the jaws 601. The lifting cylinder 3 drives the follower suspension seat 5 and the clamping cylinder 6 to move upward, and the supporting bracket 7 moves inward synchronously. The supporting rod 701 moves to the bottom of the oil barrel 9 to support and prevent the oil barrel from falling.

[0032] The working principle of this embodiment: During operation, the piston rod of the lifting cylinder 3 extends downward and passes through the lifting seat plate 2 to be connected to the follower suspension seat 5. The follower suspension seat 5 not only bears the clamping cylinder 6 but also realizes the linkage with the supporting bracket 7 through the design of its bottom plane. The clamping cylinder 6, as a double-headed cylinder, has jaws 601 assembled at the ends of its piston rods. These jaws are annularly distributed around the oil barrel and can firmly clamp the upper barrel edge of the oil barrel to ensure stability during the transfer process.

[0033] When it is necessary to transfer the oil barrel, the operator first pulls the pull rod 102 and easily moves the transfer vehicle frame to the designated position by using the universal wheels 101 at the bottom of the vehicle frame. Subsequently, the lifting cylinder 3 is activated, and the piston rod moves downward to drive the follower suspension seat 5 and the clamping cylinder 6 to descend. The jaws 601 accurately clamp the oil barrel. At this time, the pulling plate 501 at the bottom of the follower suspension seat 5 interacts with the pin shaft 702 on the supporting bracket 7 through the pulling hole 502, so that the supporting bracket slides outward with the assistance of the buffer rod 703 and the spring 704 to make room for the entry or exit of the oil barrel.

[0034] Once the oil barrel is firmly clamped, the lifting cylinder 3 is activated again, and the piston rod moves upward, driving the follower suspension seat 5 and the oil barrel to rise together. During the rising process, the pulling plate 501 continues to guide the supporting bracket 7 to slide inward through the pin shaft 702 until the supporting rod 701 on the supporting bracket 7 moves to the bottom of the oil barrel to play a supporting role and prevent the oil barrel from falling during the transfer process. At the same time, the clamping block 705 on the supporting bracket 7 and the anti-slip strip 7051 thereon closely fit the outer wall of the oil barrel, effectively preventing the oil barrel from rotating during the transfer process and further enhancing the safety of the transfer.

[0035] In addition, the alignment frame 8 provided at the bottom of the inner end of the transfer vehicle frame 1, with the alignment backing plate 801 and the buffer side column 802 thereon designed, can not only play a guiding and alignment role when the oil drum enters the vehicle frame, but also protect the oil drum from collision damage through the buffer design. The entire transfer process is smooth and efficient, greatly improving the automation level and operation efficiency of the oil drum transfer.

[0036] In this article, the following points need to be noted: 1. The attached drawings of the embodiments of the present invention only relate to the structures involved in the embodiments of the present invention, and other structures can refer to the general design.

[0037] 2. Without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other to obtain new embodiments.

[0038] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
