Description

Technical Field

[0001] This utility model relates to the field of lifting platform technology, specifically an anti-tipping lifting platform. Background Technology

[0002] A lifting platform is a common piece of woodworking machinery, mainly used to support the lifting of boards or beams and columns, facilitating further cutting or drilling.

[0003] Most woodworking lifting platforms on the market are similar in overall structure, typically hydraulic scissor lifts. They use electric cylinders to extend and retract the scissor frame, which in turn raises and lowers the platform. However, they have some functional shortcomings in actual use and have room for improvement. For example, when placing heavy materials such as beams or columns on the platform, if the weight is unbalanced, the lifting platform is prone to tipping over, posing a safety hazard. They also lack a stable anti-tipping function.

[0004] Now, a new type of anti-tipping lifting platform is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-tipping lifting platform to solve the problem mentioned in the background art of not having a stable anti-tipping function.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-tipping lifting platform, comprising a bottom fixed frame, with scissor lift limit rails fixedly connected to the front and rear ends of the bottom fixed frame, an electric cylinder mounting base fixedly connected to the right side of the bottom fixed frame, a steel structure platform plate above the bottom fixed frame, a steel structure scissor lift movably connected between the scissor lift limit rails and the steel structure platform plate, a second electric cylinder movably installed between the electric cylinder mounting base and the steel structure scissor lift, a PLC controller fixedly connected to the front end of the steel structure platform plate, and a fixing component for easy reinforcement and anti-tipping of the bottom fixed frame.

[0007] The fixing assembly includes four sets of cylindrical fixing shells, which are respectively fixedly connected to the four corners at the top of the bottom fixing frame. Limiting tubes are welded to the left and right sides of each cylindrical fixing shell. Tubular support feet are vertically inserted into the inside of each limiting tube. Miniature electric cylinders are fixedly installed inside each tubular support foot. Rubber cups are glued to the bottom of each tubular support foot. Four sets of PVC pads are provided below the bottom fixing frame. Strong adhesive is evenly coated on the bottom of each PVC pad. Connecting plates are welded to the top of each tubular support foot. The first electric cylinder is fixedly installed inside the cylindrical fixing shell.

[0008] As a further technical solution of this utility model, the tubular support foot and the rubber cup have the same outer diameter, and the rubber cup is elastic.

[0009] As a further technical solution of this utility model, the output end of the miniature electric cylinder is connected to the top of the rubber cup, and the miniature electric cylinder and the PLC controller are electrically connected.

[0010] As a further technical solution of this utility model, the outer diameter of the tubular support foot is adapted to the inner diameter of the limiting tube, and the tubular support foot can slide up and down along the inside of the limiting tube.

[0011] As a further technical solution of this utility model, the output end of the first electric cylinder is fixedly connected to the bottom end of the connecting plate, and the first electric cylinder and the PLC controller are electrically connected.

[0012] As a further technical solution of this utility model, positioning plates are respectively provided on the left and right sides of the steel structure platform plate. The positioning plates have internal threaded holes, and laser emitters are horizontally inserted into the internal threaded holes. A magnetic plate is fixedly connected inside the positioning plates. The laser emitters are threaded on the outside. The internal threaded holes and the laser emitters are threaded together. The left and right sides of the positioning plates and the magnetic plates are flush.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the anti-tipping lifting platform not only achieves the function of stable anti-tipping arrangement, but also achieves the function of adjustable corner height, and also achieves the function of easy marking.

[0014] (1) By setting up a bottom fixed frame, cylindrical fixed shell, limiting tube, tubular support foot, micro electric cylinder, rubber cup, PVC pad, strong glue, first electric cylinder and connecting plate, when in use, the second electric cylinder extends or retracts, which can push the steel structure scissor frame to open and close, thereby controlling the lifting of the steel structure platform plate. If the ground is tiled or relatively smooth, the tubular support foot can directly contact the ground, and the rubber cup at the bottom is attached to the ground. The micro electric cylinder is retracted by the PLC controller, and the middle position of the top of the rubber cup is lifted upward. The air pressure at the middle position of the contact surface between the rubber cup and the ground decreases to form suction. The four corners of the bottom of the lifting platform are attached to the ground, greatly increasing the stability of the installation. If the ground is cement and the surface is relatively rough, take four sets of PVC pads and remove the release paper on their surface. The side with strong glue is attached to the ground. After it is fixed, the lifting platform is placed on the PVC pad. The rubber cup directly adsorbs the PVC pad, realizing the function of stable arrangement and anti-tipping.

[0015] (2) By setting up a first electric cylinder and a connecting plate, when using it, before carrying out woodworking, it is necessary to determine whether the lifting platform is level. This can be done by using a bubble level. When it is necessary to finely adjust the height of the corner, the first electric cylinder of the corresponding corner is extended or retracted by the PLC controller. The first electric cylinder drives the tubular support foot to slide slightly along the limiting tube through the connecting plate, and the height of the corner is adjusted. The overall level of the lifting platform is also adjusted, thus realizing the function of adjustable corner height.

[0016] (3) By setting up a positioning plate, internal threaded holes, laser emitter and magnetic plate, the material is placed horizontally on the steel structure platform plate during use. Auxiliary marking can be made according to the cutting needs. The laser emitter is screwed in and fixed along the internal threaded holes on the positioning plate. Then the positioning plate is attached to the corresponding position on the side of the steel structure platform plate. The magnetic plate can be attached to the steel structure platform plate to facilitate height adjustment. The laser emitted by the laser emitter falls on the surface of the wood to serve as a reference for cutting or drilling, thus realizing the function of easy marking. Attached Figure Description

[0023] 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.

[0024] Example: Please refer to Figure 1-5 An anti-tipping lifting platform includes a bottom fixed frame 1, with scissor lift limit rails 11 fixedly connected to the front and rear ends of the bottom fixed frame 1, an electric cylinder mounting seat 12 fixedly connected to the right side of the bottom fixed frame 1, a steel structure platform plate 15 above the bottom fixed frame 1, a steel structure scissor lift 13 movably connected between the scissor lift limit rails 11 and the steel structure platform plate 15, a second electric cylinder 14 movably installed between the electric cylinder mounting seat 12 and the steel structure scissor lift 13, a PLC controller 20 fixedly connected to the front end of the steel structure platform plate 15, and a fixing component for easy reinforcement and anti-tipping at the top of the bottom fixed frame 1.

[0025] Please see Figure 1-5 An anti-tipping lifting platform also includes a fixing component, which includes four sets of cylindrical fixing shells 2. The four sets of cylindrical fixing shells 2 are respectively fixedly connected to the four corners at the top of the bottom fixing frame 1. Limiting tubes 3 are welded to the left and right sides of the cylindrical fixing shells 2. Tubular support feet 4 are vertically inserted into the inside of the limiting tubes 3. Miniature electric cylinders 5 are fixedly installed inside the tubular support feet 4. Rubber cups 6 are glued to the bottom end of the tubular support feet 4. Four sets of PVC pads 7 are set below the bottom fixing frame 1. Strong adhesive 8 is evenly coated on the bottom end of the PVC pads 7. Connecting plates 10 are welded to the top of the tubular support feet 4. A first electric cylinder 9 is fixedly installed inside the cylindrical fixing shell 2.

[0026] The tubular support foot 4 and the rubber cup 6 have the same outer diameter. The rubber cup 6 is elastic. The output end of the miniature electric cylinder 5 is connected to the top of the rubber cup 6. The miniature electric cylinder 5 and the PLC controller 20 are electrically connected to facilitate fixing and preventing tipping.

[0027] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the tubular support foot 4 can directly contact the ground, and the rubber cup 6 at its bottom is in contact with the ground. The micro electric cylinder 5 is retracted by the PLC controller 20. The middle position of the top of the rubber cup 6 is lifted upward, and the air pressure at the middle position of its contact surface with the ground decreases to form suction. The four corners of the bottom of the lifting platform are all in contact with the ground, which greatly increases the stability of the installation.

[0028] The outer diameter of the tubular support foot 4 is compatible with the inner diameter of the limiting tube 3. The tubular support foot 4 can slide up and down along the inside of the limiting tube 3. The output end of the first electric cylinder 9 is fixedly connected to the bottom end of the connecting plate 10. The first electric cylinder 9 and the PLC controller 20 are electrically connected, which facilitates the adjustment of the corner height.

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the first electric cylinder 9 at the corresponding corner is extended or retracted by the PLC controller 20. The first electric cylinder 9 drives the tubular support foot 4 to slide slightly along the limiting cylinder 3 through the connecting plate 10, thereby adjusting the height of the corner and the overall level of the lifting platform.

[0030] Positioning plates 16 are respectively provided on the left and right sides of the steel structure platform plate 15. The positioning plate 16 has an internal threaded hole 17. A laser emitter 18 is horizontally inserted into the internal threaded hole 17. A magnetic plate 19 is fixedly connected inside the positioning plate 16. The laser emitter 18 is threaded on the outside. The internal threaded hole 17 and the laser emitter 18 are threaded together. The left and right sides of the positioning plate 16 and the magnetic plate 19 are flush to facilitate auxiliary marking.

[0031] Specifically, such as Figure 1 and Figure 5 As shown, the laser emitter 18 is screwed into and fixed along the internal thread hole 17 on the positioning plate 16. Then, the positioning plate 16 is attached to the corresponding position on the side of the steel structure platform plate 15. The magnetic plate 19 can be attached to the steel structure platform plate 15 for easy height adjustment. The laser emitted by the laser emitter 18 falls on the surface of the wood to serve as a reference for cutting or drilling.

[0032] Working principle: When using this utility model, firstly, the second electric cylinder 14 extends or retracts, which pushes the steel structure scissor lift 13 to open and close, thereby controlling the lifting and lowering of the steel structure platform plate 15. If the ground is tiled or relatively smooth, the tubular support foot 4 can directly contact the ground, and its bottom rubber cup 6 adheres to the ground. The micro electric cylinder 5 is retracted through the PLC controller 20, and the middle position of the top of the rubber cup 6 is lifted upward. The air pressure at the middle position of its contact surface with the ground decreases, forming a suction force. The four corners of the bottom of the lifting platform are all adsorbed to the ground, greatly increasing the stability of the installation. If the ground is cement and the surface is relatively rough, take four sets of PVC pads 7, remove the release paper from their surfaces, and adhere the strong adhesive 8 side to the ground. After it is fixed, place the lifting platform on the PVC pads 7, and the rubber cup 6 directly adsorbs the PVC pads 7. Before commencing woodworking, ensure the lifting platform is level. This can be done using a bubble level. For minor adjustments to corner height, the PLC controller 20 extends or retracts the corresponding first electric cylinder 9. The first electric cylinder 9, via the connecting plate 10, drives the tubular support leg 4 to slide slightly along the limiting tube 3, thus adjusting the corner height and overall level of the lifting platform. The material is placed horizontally on the steel structure platform plate 15. Auxiliary markings can be used as needed for cutting. The laser emitter 18 is screwed into and fixed along the internal threaded hole 17 on the positioning plate 16. The positioning plate 16 is then attached to the corresponding side of the steel structure platform plate 15. The magnetic plate 19 can be attached to the steel structure platform plate 15 for easy height adjustment. The laser emitted by the laser emitter 18 falls on the surface of the wood, serving as a reference for cutting or drilling.
