[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a construction hoisting equipment, including: a hoisting box 1, with two limiting plates 9 symmetrically arranged inside the hoisting box 1, and guide rods 7 installed at the four corners of one end of the two limiting plates 9. Guide holes 8 are correspondingly opened on the surface of the hoisting box 1 near each guide rod 7. The ends of the two limiting plates 9 that are far apart from each other are connected to moving mechanisms 5. Transmission mechanisms 4 are arranged on the side walls of the hoisting box 1 near the two sets of moving mechanisms 5. A stop door 2 is hinged to the end of the hoisting box 1 away from the transmission mechanism 4. Lifting rings 3 are fixedly installed at the four corners of the top of the hoisting box 1. One end of the stop door 2 is hinged to the hoisting box 1 through a hinge (not shown in the figure), and the other end of the stop door 2 is fixedly connected to the hoisting box 1 through a latch (not shown in the figure), so as to close the stop door 2 when hoisting the hoisting box 1. Several ball bearings 6 are rotatably mounted on the bottom ends of both limiting plates 9. Each ball bearing 6 is in rolling contact with the inner bottom wall of the hanging box 1, and there is a small gap between the side walls of the two limiting plates 9 and the hanging box 1, making the movement of the two limiting plates 9 smoother. One end of each guide rod 7 is fixedly mounted on the adjacent limiting plate 9, and the other end of each guide rod 7 slides through the adjacent guide hole 8, which can guide the movement of the limiting plates 9.

[0025] Both sets of moving mechanisms 5 include bidirectional lead screws 51. Nut seats 52 are threaded onto the outer ends of both bidirectional lead screws 51. Limiting grooves 53 are correspondingly formed on the inner walls of the lifting box 1 near the four nut seats 52. Connecting rods 54 are connected between the two limiting plates 9 and adjacent nut seats 52. Mounting shaft seats 55 are installed at both ends of the four connecting rods 54. Since the length of each connecting rod 54 is fixed, when two adjacent nut seats 52 move away from each other, the included angle between the two adjacent connecting rods 54 increases, thereby pulling the limiting plate 9 towards the adjacent nut seat 52. When the seats 52 approach each other, the included angle between the two adjacent connecting rods 54 decreases, thereby pushing the limiting plate 9 to move away from the adjacent nut seat 52, realizing the function of centering and adjusting the distance between the two limiting plates 9 through the transmission structure 4 and the two sets of moving structures 5; one end of the two bidirectional lead screws 51 is rotatably mounted on the inner wall of the adjacent limiting groove 53, and the other end of the two bidirectional lead screws 51 rotatably passes through the hanging box 1 and extends out of the hanging box 1. The end of the two bidirectional lead screws 51 located outside the hanging box 1 is fixedly connected to the adjacent driven pulley 44, and the bidirectional lead screws 51 can be driven to rotate through the driven pulley 44. The longitudinal section of the four connecting rods 54 is T-shaped. One end of the four nut seats 52 is slidably connected to the inner wall of the adjacent connecting rod 54, and the other end of the four nut seats 52 is fixedly mounted with a mounting shaft seat 55. When the bidirectional lead screws 51 rotate in the two adjacent limiting grooves 53, under the limiting action of the limiting grooves 53 on the nut seats 52, they can drive the two adjacent nut seats 52 to move away from or towards each other. The four connecting rods 54 are all fixedly installed with rotating shafts 56 at both ends. The four rotating shafts 56 are inserted into the adjacent mounting shaft seats 55 and are rotatably connected to the inner wall of the mounting shaft seats 55. The two limiting plates 9 are fixedly connected to the two adjacent mounting shaft seats 55 at their far ends. Each mounting shaft seat 55 is U-shaped.

[0026] The transmission mechanism 4 includes a driving pulley 42 and two driven pulleys 44. A motor 41 is connected to one end of the driving pulley 42's shaft. A belt 43 connects the driving pulley 42 and the two driven pulleys 44. The motor 41 is fixedly mounted on the hoisting box 1, and its output shaft is fixedly connected to one end of the driving pulley 42's shaft. Under the transmission action of the driving pulley 42, belt 43, and two driven pulleys 44, when the motor 41 drives the driving pulley 42 to rotate, it can drive the two driven pulleys 44 to rotate synchronously. A protective cover 45 is fixedly installed on the side wall of the hoisting box 1 near the motor 41. The motor 41, driving pulley 42, belt 43, and two driven pulleys 44 are all located inside the protective cover 45, which protects the motor 41, driving pulley 42, belt 43, and two driven pulleys 44.

[0027] When this device is in operation, rotating the stop door 2 at one end of the hoisting box 1 opens it, facilitating the placement of construction materials inside the hoisting box 1. As the amount of construction materials needs to be adjusted, the internal space of the hoisting box 1 is adjusted. Through the transmission mechanism 4 at one end of the hoisting box 1, the two driven pulleys 44 are driven synchronously by the motor 41, the driving pulley 42, the belt 43, and the driven pulley 44. This drives the two double-acting lead screws 51 to rotate synchronously. The moving mechanisms 5 on both sides of the two limiting plates 9 allow the double-acting lead screws 51, nut seats 52, connecting rods 54, and mounting brackets to move synchronously. Under the transmission action of the mounting seat 55, when the two nut seats 52 located on the same bidirectional lead screw 51 move away from each other or move closer to each other, they can drive the two limiting plates 9 to move away from each other or move closer to each other. Through the guiding action of the guide hole 8 on the guide rod 7, the limiting plates 9 can be guided when they move, and the positions of the two limiting plates 9 can be adjusted in the center, which makes it easier to adjust the size of the internal space of the hoisting box 1. The materials inside the hoisting box 1 can be pressed and limited on both sides, so that the materials inside the hoisting box 1 are not easy to move during hoisting and transportation, so as not to affect the stability of the hoisting box 1.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
