Description

Technical Field

[0001] This utility model relates to the technical field of coating production line accessories, specifically to a lifting platform. Background Technology

[0002] A coating production line is an automated production line that integrates multiple functions such as pretreatment, coating, drying, and inspection. It operates continuously or intermittently, treating workpieces through a series of process steps to coat them with one or more layers of paint (such as oil paint, powder coating, etc.), thereby improving the workpiece's appearance, corrosion resistance, wear resistance, and other surface properties. It is widely used in industries such as automotive, home appliances, machinery, light industry, and construction. In painting production lines, a large number of platforms are often fixed in place for personnel to operate or maintain the equipment. However, due to the significant differences in the size of the equipment in the painting production line, the fixed platforms limit the range of movement for personnel, affecting the efficiency of their operation or maintenance.

[0003] Based on this, we propose a lifting platform to solve the above problems. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this utility model provide a lifting platform, which solves the technical problem that the fixed platform in the prior art restricts the range of personnel's activities and affects the efficiency of personnel's operation or maintenance.

[0005] According to one aspect, at least one embodiment of the present invention provides a lifting platform, comprising: The support plate and platform frame are provided with an adjustment assembly between them, the adjustment assembly being used to adjust the vertical height of the platform frame; Two guardrails are fixedly connected to the two sides of the top of the platform frame, and each end of the platform frame has an entrance in the middle. Two sets of support shafts are rotatably connected to both ends of the platform frame. Each support shaft is fixedly connected to a guide frame on its outer side. Multiple climbing poles are fixedly connected between the guide frames at the same end. Two transmission components are respectively mounted at both ends of the bottom of the platform frame for closing the entrance when not in use.

[0006] For example, in at least one embodiment of the present invention, a lifting platform includes a guardrail comprising: Two storage cylinders are fixedly connected to the two ends of the top of the support plate, and a crossbeam is fixedly connected between the two storage cylinders on the same side. A guide rod is vertically slidably connected inside the storage cylinder, and the top end of the guide rod is fixedly connected to the bottom end of the platform frame. Two hydraulic cylinders are fixedly connected to the two ends of the top of the support plate, and the output end of the hydraulic cylinders is fixedly connected to the bottom end of the platform frame.

[0007] For example, in a lifting platform provided by at least one embodiment of the present invention, the transmission assembly includes: A transmission frame is fixedly connected to the bottom of the platform frame. A central shaft is rotatably connected to the inner side of the transmission frame. Both ends of the central shaft are fixedly connected to transmission spur gears. An acceleration spur gear is fixedly connected to the outer side of the support shaft, and the acceleration spur gear meshes with the corresponding transmission spur gear. An eccentric plate is fixedly connected to the middle of the central shaft. A mounting rod is fixedly connected to the end of the eccentric plate away from the central shaft. An assembly ear is fixedly connected to the inner side of the transmission frame. An electric push rod is rotatably connected to the assembly ear, and the output end of the electric push rod is also rotatably connected to the mounting rod.

[0008] For example, in at least one embodiment of the present invention, a lifting platform is provided, which further includes: a through groove is provided in the middle of the platform frame, and an anti-kick plate is fixedly connected to the edge of the through groove.

[0009] For example, in at least one embodiment of the present invention, a lifting platform is provided, which further includes: the guide frame is L-shaped, and an anti-slip sleeve is fixedly connected to the outer side of the guide frame.

[0010] For example, in at least one embodiment of the present invention, a lifting platform is provided, which further includes: both ends of the support plate are fixedly connected with reinforcing rods at an incline, and the top end of the reinforcing rods is fixedly connected to a storage cylinder.

[0011] For example, in at least one embodiment of the present invention, a lifting platform is provided, which further includes: the diameter of the transmission spur gear is larger than the diameter of the acceleration spur gear.

[0012] For example, in a lifting platform provided in at least one embodiment of the present invention, the following is also included: a light rod is fixedly connected to the tail of the electric push rod, a through hole is opened in the middle of the mounting ear, and the light rod is also rotatably connected inside the through hole.

[0013] The beneficial effects of this utility model are as follows: In this invention, the structural cooperation between the platform frame and the adjustment components ensures stable adjustment of the vertical height of the platform frame under load capacity, effectively improving overall flexibility and adapting to the operation and maintenance of coating equipment in different locations.

[0023] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] like Figures 1-5 As shown, a lifting platform according to one embodiment of the present invention is illustrated, comprising: The support plate 1 and the platform frame 2 are connected by an adjustment assembly 3, which is used to adjust the vertical height of the platform frame 2. Two guardrails 4 are fixedly connected to the two sides of the top of the platform frame 2 respectively, and the middle of both ends of the platform frame 2 has an entrance 5; Two sets of support shafts 6 are rotatably connected to both ends of the platform frame 2. Each support shaft 6 is fixedly connected to a guide frame 7 on its outer side. Multiple climbing poles 8 are fixedly connected between the guide frames 7 at the same end. Two transmission components 9 are respectively assembled at both ends of the bottom of the platform frame 2, and are used to close the entrance 5 when not in use; For example, such as Figure 4 As shown, a through groove 22 is provided in the middle of the platform frame 2, and an anti-kick plate 23 is fixedly connected to the edge of the through groove 22.

[0025] More specifically, the through slot 22 can avoid the painting equipment, and personnel can walk on the platform frame 2. When they reach the required position on the painting equipment, they can carry out maintenance or other operations. For example, such as Figure 4 As shown, the guide frame 7 is L-shaped, and an anti-slip sleeve is fixedly connected to the outer side of the guide frame 7.

[0026] More specifically, through the structural characteristics of the guide frame 7, it is possible to bring the guide frame 7 closer to the guardrail 4 without affecting personnel climbing, thereby shortening the distance between the guardrail 4 and the guide frame 7 and preventing workers from falling through the gap; For example, such as Figure 3 As shown, guardrail 4 includes: Two storage cylinders 11 are fixedly connected to the two ends of the top of the support plate 1 respectively. A crossbeam 12 is fixedly connected between the two storage cylinders 11 on the same side. A guide rod 13 is vertically slidably connected inside the storage cylinder 11, and the top end of the guide rod 13 is also fixedly connected to the bottom end of the platform frame 2. Two hydraulic cylinders 10 are fixedly connected to the two ends of the top of the support plate 1, and the output end of the hydraulic cylinder 10 is fixedly connected to the bottom end of the platform frame 2.

[0027] More specifically, each of the multiple hydraulic cylinders 10 has a pressure control valve to adjust the pressure of each hydraulic cylinder 10, ensuring synchronization under different load conditions; In this embodiment, both the hydraulic cylinder 10 and the storage cylinder 11 are connected to the support plate 1 by bolts, and the crossbeam 12 is fastened to the storage cylinder 11 by bolts. For example, such as Figure 3As shown, both ends of the support plate 1 are fixedly connected with reinforcing rods at an incline, and the top of the reinforcing rods is also fixedly connected to the storage tube 11.

[0028] More specifically, the reinforcement rods provide auxiliary support for the storage tube 11, ensuring the stability of its application. More specifically, both the storage tube 11 and the guide slide rod 13 are rectangular. The rectangular structure ensures that the storage tube 11 will not undergo uncontrollable displacement inside the guide slide rod 13. For example, such as Figure 5 As shown, the transmission assembly 9 includes: A transmission frame 14 is fixedly connected to the bottom of the platform frame 2. A central shaft 15 is rotatably connected to the inner side of the transmission frame 14. Both ends of the central shaft 15 are fixedly connected to transmission spur gears 16. An acceleration spur gear 17 is fixedly connected to the outer side of the support shaft 6, and the acceleration spur gear 17 meshes with the corresponding transmission spur gear 16. An eccentric plate 18 is fixedly connected to the middle of the central shaft 15. A mounting rod 19 is fixedly connected to the end of the eccentric plate 18 away from the central shaft 15. An assembly ear 20 is fixedly connected to the inner side of the transmission frame 14. An electric push rod 21 is rotatably connected to the assembly ear 20, and the output end of the electric push rod 21 is also rotatably connected to the mounting rod 19.

[0029] For example, such as Figure 5 As shown, the diameter of the transmission spur gear 16 is larger than the diameter of the acceleration spur gear 17.

[0030] More specifically, by changing the diameter of the transmission spur gear 16 and the acceleration spur gear 17, the transmission ratio of the transmission spur gear 16 and the acceleration spur gear 17 can be increased, causing the support shaft rod 6 to rotate faster. In other embodiments, in order to prevent the adhesion of dust and impurities from affecting the connection between the transmission spur gear 16 and the acceleration spur gear 17, a housing may be provided between the transmission spur gear 16 and the acceleration spur gear 17. For example, such as Figure 5 As shown, a smooth rod is fixedly connected to the tail of the electric push rod 21, and a through hole is opened in the middle of the mounting ear 20, and the smooth rod is also rotatably connected inside the through hole. More specifically, the presence of the through hole allows the electric push rod 21 to be stably mounted on the mounting ear 20 with the help of the smooth rod, and in order to reduce the friction between the smooth rod and the through hole, a ball bearing is also provided at the connection between the smooth rod and the through hole. Working principle: First, the entire assembly is placed in the painting workshop, with the painting equipment located inside the through groove 22. When it is necessary to operate or repair the painting equipment, the electric push rod 21 is activated first, causing it to push the eccentric plate 18. Since the eccentric plate 18 is supported by the central shaft 15, it can drive the transmission spur gear 16 to rotate through the central shaft 15. This causes the transmission spur gear 16 to shift the acceleration spur gear 17, which, with the help of the acceleration spur gear 17 and the support shaft 6, drives the guide frame 7 to rotate until the guide frame 7 is adjusted to the desired position. Figure 4 As shown, personnel then use climbing pole 8 and enter the platform frame 2 through entrance 5. They then activate electric push rod 21 again to pull eccentric plate 18 until guide frame 7 flips to the desired position. Figure 1 As shown, this is used to block entrance 5 to prevent personnel from falling from entrance 5 during operations; Furthermore, during personnel operation, the hydraulic cylinder 10 can be activated to push the platform frame 2, causing the platform frame 2 to move vertically under the guidance of the guide slide rod 13, thereby changing the height of the platform frame 2 to adapt to the operation requirements of coating equipment at different heights, making the whole more flexible and greatly improving its overall applicability.

[0031] In summary, through the structural cooperation of the platform frame 2 and the adjustment component 3, the vertical height of the platform frame 2 can be stably adjusted under load capacity, effectively improving the overall flexibility and adapting to the operation and maintenance of coating equipment in different locations.

[0032] Through the structural cooperation of the support shaft 6 and the transmission component 9, the entrance 5 can be blocked by the flipping of the guide frame 7 when it is not in use, making the operation of personnel safer. It can also compensate for the height difference between the platform frame 2 and the ground when personnel enter the platform frame 2, effectively ensuring the convenience of the overall application.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
