Description

Technical Field

[0001] This application relates to the field of civil engineering construction tools, and in particular to an electric lifting support for loading and unloading goods. Background Technology

[0002] During civil construction, the transfer of building materials is frequent, and the handling of building materials is generally divided into manual handling and mechanical handling. Manual handling is mainly done by workers, usually with the help of some simple tools, such as handcarts and ropes. Its handling efficiency is low, but the cost is low, and it is suitable for small-batch handling. Mechanical handling, on the other hand, uses mechanical equipment such as forklifts and cranes to move building materials. Its handling efficiency is high, but the cost is high, and it is suitable for large-scale handling.

[0003] Because the handling of building materials on construction sites is usually done in small batches and in a relatively dispersed manner, it is mainly carried out manually. When it is necessary to move building materials from a lower position to a higher position, such as moving building materials from a stacking point to a transport vehicle, or from the ground to a construction scaffold, the traditional method is as follows: a worker standing at a lower position lifts the goods, and a worker standing at a higher position bends over to receive the goods; or the goods are first tied with ropes, and then a worker standing at a higher position uses ropes to lift the goods from the lower position to the higher position. This method is not only labor-intensive, but also poses a risk of injury from falling goods during the lifting or hoisting process, making it difficult to meet the needs of use. Utility Model Content

[0004] To address or partially address the problems existing in related technologies, this application provides an electric lifting support for loading and unloading goods. This device can smoothly transport goods from a lower position to a higher position without relying on manual handling, thereby reducing the labor intensity of workers and preventing goods from falling and injuring people, thus improving safety.

[0005] This application provides an electrically operated lifting support for loading and unloading goods, comprising:

[0006] frame;

[0007] The loading platform includes a base plate, a loading plate, and an electric telescopic rod. The base plate is slidably connected to the frame, and the loading plate is rotatably mounted on the base plate. One end of the electric telescopic rod is hinged to the base plate, and the other end is hinged to the loading plate. The tilt angle of the loading plate can be adjusted by controlling the extension of the electric telescopic rod.

[0008] The drive mechanism enables the cargo platform to slide on the frame.

[0009] Optionally, in some embodiments, the frame has a sliding groove.

[0010] Optionally, in some embodiments, the loading platform further includes roller frames and rollers. There are two roller frames, which are symmetrically mounted on the base plate, and the distance between the two roller frames corresponds to the width of the frame. Several rollers are rotatably mounted on the roller frames, and the rollers are tactilely connected in the slide groove.

[0011] Optionally, in some embodiments, the drive mechanism includes a motor, a drive wheel, a driven wheel, and a steel rope. The drive wheel is rotatably mounted at one end of the frame, and the driven wheel is rotatably mounted at the other end of the frame. The drive wheel and the driven wheel are connected by a steel rope. The motor can drive the drive wheel to rotate, thereby driving the steel rope to rotate.

[0036] See Figure 1-6 An electric lifting support for loading and unloading goods, comprising:

[0037] The frame 1 is rectangular in shape and welded from square steel. Slots 14 are provided on both long sides of the frame 1, and a support leg 11 is welded to one end of the frame 1, while a bracket 12 is welded to the other end. (See also...) Figure 1 In use, the frame 1 is tilted and erected at a height difference, with the legs 11 contacting the ground to support the frame 1. The support bracket 12 is then placed on the edge of the higher position to complete the erection. Furthermore, the legs 11 can be treated with anti-slip material to improve stability during use. For example, when used on a concrete floor, rubber anti-slip sleeves can be fitted onto the outside of the legs 11 to increase friction between the legs 11 and the ground.

[0038] The loading platform 2 includes a base plate 21, a loading plate 26, and an electric telescopic rod 29. Two roller frames 22 are fixedly installed on the side of the base plate 21 facing the frame 1. The two roller frames 22 are symmetrically arranged, and the distance between them corresponds to the width of the frame 1. Several rollers 23 are rotatably mounted on the roller frames 22, and the rollers 23 are rolled within the sliding grooves 14, allowing the base plate 21 to slide along the frame 1. The number of rollers 23 can be adjusted according to requirements; generally, the more rollers 23 there are, the stronger the load-bearing capacity of the loading platform 2. Furthermore, two first supports 25 are symmetrically arranged on the side of the base plate 21 facing away from the frame 1, and a carrying plate 26 is hinged between the two first supports 25. A second support 27 is also provided on the base plate 21, and a third support 28 is provided on the carrying plate 26. One end of the electric telescopic rod 29 is hinged to the second support 27, and the other end is hinged to the third support 28. By controlling the extension of the electric telescopic rod 29, the tilt angle of the carrying plate 26 can be adjusted, so that the carrying plate 26 is always horizontal, which is convenient for placing goods. The reason for this design is that since the length of the frame 1 is fixed, the greater the height difference between the lower and higher positions, the steeper the frame 1 is when erected. When the height difference is smaller, the frame 1 is more gentle. In order to adapt to the conveying of different height differences, the carrying plate 26 can be adjusted by the electric telescopic rod 29 to keep it in a horizontal state, which is convenient for placing goods. The number of electric telescopic poles 29 can be adjusted according to needs. In this embodiment, two electric telescopic poles 29 are symmetrically arranged for better stability. Alternatively, a single electric telescopic pole 29 can be used, which is more cost-effective.

[0039] The drive mechanism 3 drives the loading platform 2 to slide on the frame 1, thereby replacing manual handling. The drive mechanism 3 includes a motor 31, a drive wheel 34, a driven wheel 38, and a steel cable 39. A first wheel frame 32 is located at one end of the frame 1, and a second wheel frame 37 is located at the other end. A rotating shaft 33 is rotatably mounted on the first wheel frame 32. The drive wheel 34 is fixedly connected to the rotating shaft 33, and the driven wheel 38 is rotatably mounted on the second wheel frame 37. The drive wheel 34 and the driven wheel 38 are connected by a steel cable 39, which has a ring-shaped structure. A V-shaped groove is formed on the drive wheel 34, and one end of the steel cable is connected to the V-shaped groove to increase friction and prevent slippage of the steel cable 39. A U-shaped groove is formed on the driven wheel, and the other end of the steel cable is connected to the U-shaped groove to guide the steel cable 39 and prevent it from slipping. Furthermore, a mounting plate 15 is welded and fixed to the frame 1. The motor 31 is fixed to the mounting plate 15 with bolts and nuts. A sprocket 35 is also fixedly connected to the rotating shaft 33. The sprocket 35 and the motor 31 are connected by chain drive, so that the motor 31 can drive the drive wheel 34 to rotate, thereby driving the steel rope 39 to rotate. A connecting block 24 is also provided on the base plate 21. The connecting block 24 is fixedly connected to the steel rope 39, so that when the steel rope 39 rotates, it can drive the base plate 21 to move synchronously, realizing the sliding of the loading platform 2 on the frame 1. By controlling the forward and reverse rotation of the motor 31, the sliding direction of the loading platform 2 can be changed. It should be noted that the circuit structure and control method of the motor 31 are existing technologies. Those skilled in the art can adjust them according to their needs, and will not be described in detail here.

[0040] Based on the above embodiments, to improve the load-bearing capacity of the frame 1, reinforcing rods 13 are uniformly welded onto the frame 1; to facilitate the movement of the frame 1, a connecting frame 41 is also welded onto the frame 1, and a movable wheel 4 is rotatably mounted on the connecting frame 41. The installation position of the movable wheel 4 can be adjusted according to requirements. Generally, when setting up the frame 1, it is necessary to ensure that the movable wheel 4 can leave the ground, thereby ensuring the stability of the device during use. In some special cases, such as when the height difference is small and the movable wheel 4 cannot leave the ground, locking blocks can be placed on both sides of the movable wheel 4 to fix it. Alternatively, movable wheels 4 with self-locking function can be selected during installation. Those skilled in the art can flexibly adjust the specific method according to the actual situation.

[0041] Specific work process:

[0042] Move the device to a position with a height difference, tilt the frame 1 so that the support legs 11 contact the ground to support the frame 1, and place the support bracket 12 on the edge of the higher position to complete the erection; by controlling the electric telescopic rod 29, adjust the carrying platform 26 to be horizontal, place the building materials on the carrying platform 26, start the motor 31, the motor 31 drives the drive wheel 34 to rotate, thereby driving the steel cable 39 to rotate, and the steel cable 39 drives the carrying platform 2 to rise. When the carrying platform 2 rises to the top, stop the motor 31, and the workers unload the goods to complete the conveying. Conversely, this device can also be used to convey goods from a higher position to a lower position.
