[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] Reference Figure 1-Figure 3 The utility model provides an embodiment: a steel structure mounting frame for a city exhibition hall, comprising a support frame 1 for fixed support, the top of the support frame 1 is fixedly connected to a support top plate 2 for supporting the steel structure of the exhibition hall, the bottom of the support top plate 2 is fixedly connected to a pulley assembly, the pulley assembly comprises a fixed pulley 3, the top of the fixed pulley 3 is fixedly connected to the bottom end of the support top plate 2, the fixed pulley 3 is arranged in four groups, evenly distributed on the four sides of the bottom of the support top plate 2, the bottom end of the support top plate 2 is fixedly connected to a fixed pulley 2 4. The fixed pulley 2 4 is provided with four groups, which are evenly distributed on the four sides of the bottom of the supporting top plate 2. The fixed pulley 1 3 is located on the outside of the fixed pulley 2 4. A pulley assembly is wound with a draw rope 5, and the inside of the draw rope 5 is wound on a group of fixed pulleys 1 3 and fixed pulley 2 4 in the same direction. The pulley assembly is used to change the direction of the draw rope 5. A fixing rod 6 is wound around one end of the draw rope 5 for conveniently fixing the draw rope 5. Both ends of the fixing rod 6 are fixedly connected to the inner side of the support frame 1, and the other end of the draw rope 5 is fixedly connected to a fixing block 7 that plays a fixed connection role.

[0033] Reference Figure 2-Figure 4, the bottom of the fixed block 7 is fixedly connected to a slide rod 8, and the front of the slide rod 8 is fixedly connected to a T-shaped frame 9 that plays a fixed connection role. The front of the T-shaped frame 9 is rotatably connected to a threaded column 10, and a threaded plate 11 is threadedly connected to the threaded column 10. By rotating the threaded column 10, the threaded column 10 can drive the threaded plate 11 to slide along the length direction of the threaded column 10. A positioning column 12 is slidably connected to the threaded plate 11. The positioning column 12 is provided with two groups, and the two groups of positioning columns 12 are symmetrically arranged on the threaded plate 11 so that the threaded plate 11 will not rotate. One end of the positioning column 12 is fixedly provided on the vertical plate of the T-shaped frame 9, and the bottom of the threaded plate 11 is fixedly connected to the square The clamping plate 13 is clamped, and a positioning slide groove 14 is provided on the outer side of the horizontal plate of the T-frame 9. There are two positioning slide grooves 14, which are symmetrically arranged on the left and right sides of the horizontal plate of the T-frame 9. The connecting plate is slidably arranged in the positioning slide groove 14, and the connecting plate extends out of the positioning slide groove 14 and is fixedly connected to the clamping plate 13. Two vertical slide grooves 15 are symmetrically provided on the inner side of the support frame 1. There are eight vertical slide grooves 15. A vertical slide groove 15 is provided on both sides of the inner wall of the front, back, left and right sides of the support frame 1. The two ends of the slide rod 8 are slidably connected to the inside of the two vertical slide grooves 15 through a slider. The vertical slide groove 15 limits the slide rod 8 to only slide up and down along the inner wall of the vertical slide groove 15.

[0034] Reference Figure 2 and Figure 5 , the outer side of the support frame 1 is hinged with a limit sleeve 16, and the limit sleeve 16 is provided with eight groups, which are evenly distributed on the left and right sides of the four sides of the support frame 1. A limit groove 17 is provided inside the limit sleeve 16, and a pressure sensor 18 is fixedly connected to the inner wall of the bottom end of the limit groove 17. When the top of the pressure sensor 18 is compressed, a current signal is generated. A pressure plate 19 is slidably connected to the inside of the limit groove 17. The limit groove 17 limits the pressure plate 19 to slide up and down only along the inner wall of the limit groove 17. The bottom of the pressure plate 19 contacts the top of the pressure sensor 18, which will generate a signal at this time. The top of the pressure plate 19 The end is fixedly connected to a sliding column 20, which is slidably connected to the top surface of the limiting sleeve 16. The upper end of the sliding column 20 extends out of the limiting sleeve 16 and the end is hinged to the bottom of the supporting top plate 2. When the supporting top plate 2 tilts, the sliding column 20 will slide downward along the inner wall of the limiting sleeve 16. An alarm 21 is fixedly connected to the bottom of the supporting top plate 2. There are four groups of alarms 21, which are evenly distributed on the four sides of the bottom of the supporting top plate 2. The pressure sensor 18 is electrically connected to the alarm 21. When the pressure sensor 18 generates a signal, the alarm 21 will make a sound and flash to alert the security personnel.

[0035] Working Principle: When it is necessary to hang a large-format poster on the outside of the support frame 1, first loosen the pull cord 5 on the fixed rod 6 and release the pull cord 5 upward. At this time, the slide bar 8 slides downward along the inner wall of the vertical slide groove 15 due to gravity, causing the T-shaped frame 9 to slide to the bottom of the support frame 1. Then, the top of the large-format poster is placed between the T-shaped frame 9 and the clamping plate 13. The threaded column 10 is rotated. The threaded column 10 drives the threaded plate 11 to move inward. The threaded plate 11 drives the clamping plate 13 to move inward to clamp the top of the large-format poster. Then, the pull cord 5 is pulled. The pull cord 5 drives the fixed block 7 to move upward. The fixed block 7 drives the clamping plate 13 and the T-shaped frame 9 to move upward, thereby hanging the large-format poster on the outside of the support frame 1. The operation is simple, safe and reliable.

[0036] When the support top plate 2 tilts, the support top plate 2 drives the top end of the sliding column 20 on one side to move downward, and the sliding column 20 moves inward along the inner wall of the limiting sleeve 16, driving the pressure plate 19 to move downward along the limiting groove 17. When the pressure plate 19 contacts the pressure sensor 18, the pressure sensor 18 generates a signal and transmits it to the alarm 21, causing the alarm 21 to sound and flash, reminding the safety personnel that there is a problem with the support force here and timely maintenance is required.
