Description

Technical Field

[0001] The utility model relates to a tower crane detection device with an automatic early warning function, belonging to the technical field of tower crane equipment. Background Art

[0002] A tower crane is a large lifting device used on construction sites and other engineering projects. It typically consists of a tower, a rotating mechanism, and a boom. The tower crane's tower is formed by stacking and connecting multiple standard crane sections. The primary function of a tower crane is to lift heavy objects from the ground or other locations and place them in the desired location. To ensure stability and safety during operation, the crane requires measuring the inclination between adjacent standard crane sections.

[0003] However, in the prior art, the measurement of the inclination between two adjacent standard sections of the tower crane body is generally carried out by using a plumb line. When measuring with a plumb line, whether the tower body is tilted can only be observed when the surveyor is at the measuring position. When the surveyor is not there, it is impossible to observe whether there is an inclination between two adjacent standard sections of the tower body, and it is also impossible to read the inclination of two adjacent sections of the tower body.

It is worth noting that in the present utility model, there is a certain gap between the pointer 4 and the bottom surface of the dial 2, and the height of the micro switch 6 is greater than this gap.

[0025] In the present invention, the linkage assembly 3 includes a square linkage rod 301, a hexagonal groove 302 is provided in the center of the front end surface of the square linkage rod 301 close to the box body 1, a threaded hole 303 is provided at the bottom of the hexagonal groove 302, and vertical connecting rods 304 are provided at both ends of the top of the square linkage rod 301. A mounting rod 305 is provided on the opposite side of the vertical connecting rod 304 away from the end of the square linkage rod 301. The bottom of the mounting rod 305 away from the end of the vertical connecting rod 304 is fixedly connected to a spring 306, and the spring 306 is fixedly connected to a connecting block 307. The connecting block 307 is located inside the box body 1, and the two are slidably matched. Rounded corners 308 are provided on the left and right sides of the connecting block 307, and a bottom plate 309 is provided at the bottom of the connecting block 307. The bottom plate 309 is located in the box body The bottom of the box body 1, and the volume of the bottom plate 309 is larger than the bottom opening of the box body 1, the linkage shaft 7 and the pointer 4 are integrally formed, and the linkage shaft 7 is provided with a hexagonal surface 15 at one end near the square linkage rod 301, and the hexagonal surface 15 is inserted into the hexagonal groove 302.

The bolt 17 is threadedly connected with the threaded hole 303, thereby fixing the linkage shaft 7 and the pointer 4 to the square linkage rod 301. A fixing component 18 is provided on the top of the rear end surface of the box body 1 and the top of the rear end surface of the bottom plate 309. The fixing component 18 includes a group of limit plates 181, and a group of limit plates 181 are provided with a group of slots 182, and the slots 182 on different limit plates 181 are coaxially arranged with the slots 182.

[0026] In the above technical solution, by respectively arranging the fixing assembly 18 on the box body 1 and the bottom plate 309, the cross bar at the bottom of the standard section at the top of the two adjacent standard sections of the tower body can be stuck between the two limit plates 181 in the fixing assembly 18 at the top of the rear end face of the box body 1, and the fixing bolt 17 is inserted into the slot 182 on the limit plate 181. Finally, the threaded connection between the nut and the fixing bolt 17 is used to fix the present invention to the standard section at the top. The cross bar at the top of the standard section at the bottom of the two adjacent standard sections of the tower body can be stuck between the two limit plates 181 in the fixing assembly 18 at the top of the rear end face of the box body 1, and the fixing bolt 17 is inserted into the slot 182 on the limit plate 181. The fixing bolts 17 are finally connected by the threaded connection of the nut and the fixing bolts 17 to fix the present invention to the standard section at the bottom. When the tower body tilts between two adjacent standard sections, the fixing assembly 18 near the top of the rear end face of the box body 1 and the fixing assembly 18 at the rear end face of the bottom plate 309 are subjected to opposite pulling forces, which can drive the connecting block 307 to rotate in the box body 1. The rotation of the connecting block 307 causes a group of springs 306 on the top of the connecting block 307 to be deformed by the pulling force or compression force of the connecting block 307. The deformation of the spring 306 can drive the mounting rod 305, the vertical connecting rod 304, and the square cross bar to rotate with the rotating shaft as the center of the circle, thereby driving the pointer 4 in the dial 2 to rotate.

[0027] The working principle of the tower crane detection device with automatic early warning function in this utility model is:

[0028] When in use, first use the nut and the fixing bolt 17 to fix the fixing assembly 18 at the rear end face of the box body 1 in the present invention near the top position to the cross bar of the upper standard section of the two adjacent standard sections of the tower body, and then use the nut and the fixing bolt 17 to fix the fixing assembly 18 at the rear end face of the bottom plate 309 in the present invention to the cross bar of the lower standard section of the two adjacent standard sections of the tower body. When the two adjacent standard sections of the tower body are tilted, the fixing assembly 18 at the rear end face of the box body 1 near the top and the fixing assembly 18 at the rear end face of the bottom plate 309 are subjected to opposite pulling forces, which can drive the connecting block 307 to rotate in the box body 1. The rotation of the connecting block 307 makes the connecting block 307 rotate A group of springs 306 on the top of the connecting block 307 will be deformed by the pulling force or compression force of the connecting block 307. The deformation of the spring 306 can drive the installation rod 305, the vertical connecting rod 304, and the square cross bar to rotate with the rotating shaft as the center, thereby driving the pointer 4 in the dial 2 to rotate. When the pointer 4 rotates to a position outside the safe value of the inclination, the pointer 4 rotates to the position of the micro switch 6, triggering the micro switch 6. After the micro switch 6 is triggered, the power module provides power to the alarm light, so that the alarm light can light up, achieving the early warning function. The test personnel can observe that the inclination between two adjacent standard sections at any position of the tower body is within the safe value without the need for the measurement site.
