[0024] AsFigure 1 As shown in the figure, the utility model provides a compact hoisting device for communication base station construction, which includes a U-shaped base 1, two support frames 2 and a bearing plate 3. The bottoms of the two support frames 2 are respectively fixedly connected to the left and right sides of the top of the U-shaped base 1. The left and right ends of the bearing plate 3 are respectively fixedly connected to the tops of the opposite surfaces of the two support frames 2.

Two mounting plates 7 are respectively arranged on the middle side of the top of the bearing plate 3. A positioning hanging wheel 8 is rotatably connected to the opposite surfaces of the two mounting plates 7. A winding mechanism 9 is arranged in the middle of the rear side of the top of the U-shaped base 1 close to the two support frames 2. A rope 6 is fixedly connected to the top of the hanging plate 5. The rope 6 passes through the bearing plate 3 through the positioning shell 10. The outer wall of the rope 6 is lapped with the inner wall of the positioning hanging wheel 8. One end of the rope 6 away from the hanging plate 5 is arranged outside the winding mechanism 9. Two universal wheels 11 are respectively fixedly connected to the left and right sides of the bottom of the U-shaped base 1;

[0025] The U-shaped base 1, the support frames 2, the bearing plate 3, the connecting and adjusting mechanism 4, the hanging plate 5, the rope 6, the positioning hanging wheel 8 and the winding mechanism 9 are provided. Through the cooperation of the connecting and adjusting mechanism 4 and the hanging plate 5, it is convenient to install and connect the hanging plate 5 with different sizes, improving the practicability of the equipment. When hoisting communication equipment materials, by arranging sliding rods 21 on the two support frames 2 and sliding the sliders 47 in the connecting and adjusting mechanism 4 along the sliding rods 21, the stability of the materials during rising is achieved.

[0026] As Figure 2 shown in the figure, the utility model provides a technical solution for a compact hoisting device for communication base station construction: The connecting and adjusting mechanism 4 includes a fixing plate 41, a connecting plate 42 and two adjusting components 43, a bottom plate 44, two screw rods 45, two nuts 46, and two sliders 47.

The two sliders 47 are fixedly connected to the front and rear sides of the end of the fixing plate 41 away from the connecting plate 42. A hook 51 is fixedly connected to the middle side of the bottom of the hanging plate 5. Two through holes 501 penetrating up and down are respectively opened on the left and right sides of the top of the hook 51 away from the hook 51. The top of the outer wall of the screw rod 45 passes through the inside of the through hole 501 to the top of the hanging plate 5 and is threadedly connected to the inside of the nut 46. The screw rod 45 is arranged to penetrate out of the hanging plate 5 through the through hole 501, and then the nut 46 is screwed onto the screw rod 45, so as to fixedly connect the connecting and adjusting mechanism 4 and the hanging plate 5.

[0027] As Figure 3As shown in the figure, the present utility model provides a technical solution for a compact hoisting device for communication base station construction: The adjusting assembly 43 includes a fixed tube 431, a support rod 432, and a spring 433. The fixed tube 431 penetrates through the left and right ends inside the fixing plate 41 and is fixedly connected therebetween. The inside of the fixed tube 431 is sleeved with the outer wall of the support rod 432. The inside of the spring 433 is sleeved outside the support rod 432. One end of the spring 433 is fixedly connected to one end of the fixing plate 41 away from the slider 47, and the other end of the support rod 432 is fixedly connected to one end of the connecting plate 42 away from the bottom plate 44. By setting the spring 433 and utilizing the elasticity of the spring 433, the support rod 432 can expand and contract along the fixed tube 431, facilitating the adjustment of the distance between the fixing plate 41 and the connecting plate 42, and facilitating the connection of suspension trays 5 of different sizes. On the top of the slider 47, a through hole 470 that penetrates up and down is opened on one side away from the fixing plate 41. On both sides of the slider 47 near the through hole 470 in the front and rear directions, clamping grooves 471 are respectively opened. Steel balls 48 are arranged inside both clamping grooves 471.

[0028] As Figure 4 shown in the figure, the present utility model provides a technical solution for a compact hoisting device for communication base station construction: The winding mechanism 9 includes two positioning plates 91, a stepping motor 92, and a winding roller 93. The bottoms of the two positioning plates 91 are respectively fixedly connected to the middle parts of the U-shaped base 1 near the rear sides of the two support frames 2. The output shaft of the stepping motor 92 is fixedly connected to one end of the winding roller 93 through one of the positioning plates 91, and the other end of the winding roller 93 is rotatably connected to the inside of the other positioning plate 91. The end of the rope 6 away from the suspension tray 5 is wound around the outer wall of the winding roller 93. The output shaft of the stepping motor 92 drives the winding roller 93 to rotate, so as to wind the rope 6 on the winding roller 93, thereby performing an ascending operation on the suspension tray 5. On the front and rear sides of the opposite surfaces of the two support frames 2, connection grooves 201 are respectively opened. On the front and rear sides of the inner walls of the front and rear two connection grooves 201, limiting grooves 202 are respectively opened. Slide rods 21 are fixedly connected inside all four connection grooves 201.

[0029] As Figure 5 shown in the figure, the present utility model provides a technical solution for a compact hoisting device for communication base station construction: The inside of the connection groove 201 is sleeved with the outer wall of the slider 47. The outer wall of the slide rod 21 penetrates through the upper and lower ends of the slider 47 through the clamping groove 471 and is slidably connected therebetween. By arranging the slide rod 21 in the connection groove 201, the slider 47 can slide upward or downward along the slide rod 21 through the through hole 470, thereby limiting the movement track of the suspension tray 5. The inner wall of the limiting groove 202 abuts against the outer wall of the steel ball 48, and the steel ball 48 slides along the inner wall of the limiting groove 202, thereby improving the smoothness of the lifting of the suspension tray 5.

[0030] Next, the working principle of this compact hoisting device for communication base station construction will be specifically described.

[0031] As Figures 1-5 shown, first, the compact hoisting device is moved to a suitable position through the universal wheels 11. When hoisting the materials of the communication device, the screws 45 on the two side bottom plates 44 are first inserted through the jack holes 501 to the upper end of the hanging plate 5. By the elastic force of the spring 433, according to the size of the hanging plate 5, the support rod 432 contracts and moves along the inside of the fixed tube 431 and compresses the spring 433. Then, the nut 46 is screwed onto the outer wall of the upper end of the screw 45 on the hanging plate 5 to complete the installation and connection of the hanging plate 5, so that the hanging plate 5 is balanced and stable at the center of the U-shaped base 1. The materials of the communication device to be hoisted are bundled and hung on the hook 51 at the lower end of the hanging plate 5. Then, the stepping motor 92 is started, and the output shaft of the stepping motor 92 drives the winding roller 93 to rotate. The rotation of the winding roller 93 drives the rope 6 to wind and reel in, so that the rope 6 is positioned by the positioning hanging wheel 8 during the movement, driving the hanging plate 5 to move upward. During the upward movement, the slider 47 slides along the outside of the sliding rod 21 through the communication hole 470, which not only limits the movement track of the hanging plate 5, but also the steel ball 48 rolls along the limiting groove 202 to improve the smoothness of the sliding, ensuring that the hanging plate 5 is in a balanced state during the movement and improving the stability of the hook during the hoisting process.

[0032] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit and idea of the present invention are within the protection scope of the present invention.
