[0001] This utility model belongs to the field of electric flatbed cart technology, specifically an electric flatbed cart with a liftable platform. Background Technology

[0002] A rail flatcar is an electric rail-mounted transport vehicle used in factories to transport products between spans within the factory. Also known as a cross-span flatcar, trolley, or electric flatcar, it has advantages such as simple structure, ease of use, easy maintenance, high load capacity, and low pollution. It is widely used in machine manufacturing and metallurgical plants as a means of transporting heavy objects across spans in conjunction with cranes within the workshop.

[0003] In order to facilitate the loading and unloading of goods, flatbed carts usually have a certain lifting function. However, when the flatbed cart is lifted under load, the objects on the upper part of the flatbed cart are prone to shaking due to the lifting of the flatbed cart. In severe cases, the objects may even tip over. To address this issue, we have proposed an electric flatbed cart with a liftable platform. Utility Model Content

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example 1, by Figure 1-3 An electric flatbed cart with a liftable platform is provided, comprising a flatbed cart base 10, a lifting seat 20, and a platform plate 30. The lifting seat 20 is installed on the upper part of the flatbed cart base 10, and the platform plate 30 is installed on the upper part of the lifting seat 20.

[0025] The lifting platform 20 includes a drive mechanism 21 and a support mechanism 22. The support mechanism 22 is installed inside the drive mechanism 21. The drive mechanism 21 includes a motor 210 and a drive rod 211. Gears 212 are provided on both the drive shaft of the motor 210 and the right side of the drive rod 211. The two sets of gears 212 mesh with each other. A drive seat 213 is provided on the upper part of the drive rod 211. Track grooves 214 are evenly opened inside the drive seat 213. The support mechanism 22 is movably connected inside the track grooves 214. When the platform plate 30 needs to be lifted, it can be rotated by running the motor 210. The rotation of the motor 210 drives the gears 212 to rotate, and the rotation of the two sets of gears 212 drives the drive rod 211 to rotate. Furthermore, the surface of the drive rod 211 is provided with reverse-oriented threads, so that when the drive rod 211 rotates, it drives the two sets of drive seats 213 to move synchronously. The movement of the drive seats 213 drives the support mechanism 22 to move, allowing the support mechanism 22 to slide better inside the track groove 214. The track groove 214 is composed of an inclined groove and a transverse groove. When the track groove 214 slides, the support mechanism 22 will automatically rise when sliding inside the inclined groove. When the support mechanism 22 is in the transverse groove, it can effectively support the support mechanism 22. The rising of the support mechanism 22 drives the platform plate 30 to rise, and the reverse-rotating motor 210 rotates, making... To facilitate the descent of the platform plate 30, the support mechanism 22 includes a sliding rod 220. Rollers 221 are evenly distributed inside the sliding rod 220, and the rollers 221 are movably connected to the inside of the track groove 214. Support columns 222 are provided on both the front and rear sides of the sliding rod 220. The sliding rod 220 limits the position of the rollers 221, allowing them to slide better within the track groove 214. The support columns 222 also support the bottom of the platform plate 30, enabling the sliding rod 220 to better drive the support columns 222 to rise as the rollers 221 on both sides of the sliding rod 220 slide within the track groove 214. The interior of the flatbed base 10... The system includes evenly spaced tubes, with support columns 222 movably inserted inside. The tubes effectively limit the position of the bottom of the support columns 222, facilitating their lifting and lowering and preventing positional deviation. The drive base 213 includes a screw plate with a screw groove inside. Movable plates are located on both the front and rear sides of the screw plate. A track groove 214 is located on the upper part of the movable plates. The screw groove allows for better screwing of the screw plate to the drive rod 211, enabling the drive rod 211 to rotate and move the screw plate. Furthermore, the movable plates can be moved by the rotation of the screw plate.The position of the track groove 214 is adjusted by moving the movable plate. The flatbed base 10 has a sliding seat inside, and the sliding seat has a sliding groove inside. The bottom of the movable plate is located inside the sliding groove. The sliding seat limits the position of the upper part of the screw plate. The sliding grooves on both sides of the sliding seat effectively limit the position of the bottom of the movable plate, allowing for better parallel sliding. A cover is provided on one side of the lifting seat 20, matching the position of the gear 212. The cover effectively protects the gear 212 from external dust and debris.

[0026] Working principle: When the platform plate 30 needs to be raised or lowered, it can be rotated by the motor 210. The rotation of the motor 210 drives the gear 212 to rotate, and the rotation of the two sets of gears 212 drives the drive rod 211 to rotate. The surface of the drive rod 211 is provided with reverse threads, so that when the drive rod 211 rotates, it drives the two sets of drive seats 213 to move synchronously. The movement of the drive seats 213 drives the support mechanism 22 to move, so that the support mechanism 22 can slide better inside the track groove 214. The track groove 214 is composed of an inclined groove and a transverse groove. When the track groove 214 slides, the support mechanism 22 will automatically rise when sliding inside the inclined groove, and the support mechanism 22 can be effectively supported when it is in the transverse groove. The rise of the support mechanism 22 drives the platform plate 30 to rise, and the reverse rotation of the motor 210 makes the platform plate 30 lower better.
