Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a detection device for structural camber deformation. Background Art

[0002] Cranes are indispensable equipment in modern industry, widely used for various material handling and heavy lifting applications. As a crane ages, its main girder, under the pressure of its own weight, the trolley, and the hoisted load, inevitably experiences camber deformation, meaning the center section of the girder gradually bends or flexes downward. This deformation not only affects the crane's normal operation but also poses a series of safety hazards. Traditional methods for measuring crane girder camber include wire rope and tape measurement, level measurement, and transmitter and receiver measurement. The wire rope and tape measurement method is a relatively primitive method, using a wire rope secured to the girder and a tape measure for measurement. However, this method is complex, inefficient, and susceptible to significant environmental influences, making it difficult to achieve high-precision measurements. While the level measurement method can provide relatively accurate data, its operation is cumbersome, requires specialized personnel, and has limited applicability to large cranes. The transmitter and receiver measurement method uses a transmitter on the ground and a receiver at the base of the crane to transmit signals for measurement. However, this method has obvious shortcomings. For example, the transmitter needs to be re-laid each time it is used, which increases the complexity of the operation. In addition, since the receiver is set at the bottom of the crane, when the crane is deformed, the receiver will also move, resulting in inaccurate detection results.

[0003] These traditional methods have certain limitations in practical applications and cannot meet the high safety and stability requirements of modern industrial production for cranes. Therefore, it is particularly important to develop a device that can accurately detect the camber deformation of the crane main beam in real time. Utility Model Content

DETAILED DESCRIPTION

[0042] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. As long as the effects of the present invention can be exerted, various changes can be made to the embodiments.

[0043] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0044] Reference Figure 1-6 A detection device for structural camber deformation according to this embodiment is described.

[0045] It should be noted that structural camber is a type of curved camber of a structure. In this embodiment, the structure is a lifting device, which includes two crane travel rails 1, on which a crane 2 is mounted. A limiter 3 is provided at the end of the crane travel rail 1 to limit the travel of the crane 2.

[0046] The detection device includes side rails 4, a moving assembly, a beam-arm assembly, and a detection assembly. The side rails 4 are located at the ends of the two crane travel rails 1. This arrangement allows the crane 2 to travel along the crane travel rails 1 until it is stopped by the end stoppers 3. The moving assembly, carrying the beam-arm assembly and the detection assembly, moves along the length of the crane 2, detecting the crane's camber during this movement.

[0047] Specifically, the moving assembly is mounted on the side rail 4 and moves along its length. The arm assembly is mounted on the moving assembly and includes an arm plate 11. When the crane 2 stops at the stopper 3 on the crane travel rail 1, the arm plate 11 extends to the bottom of the crane 2. The detection assembly is mounted at the end of the arm plate 11. It should be noted that the detection device is located near the stopper 3.

[0048] like Figure 2 and Figure 3 As shown, the moving assembly includes a travel vehicle 5, a driving wheel 6 and a first motor 8. The driving wheel 6 is rotatably connected to the bottom of the travel vehicle 5; an auxiliary wheel 7 is provided above the travel vehicle 5, and the auxiliary wheel 7 can be arranged vertically or horizontally. The first motor 8 is fixed to the travel vehicle 5, and the output end of the first motor 8 is connected to the driving wheel 6 through a transmission belt group 12. The transmission belt group 12 includes three pulleys and a belt, two of which are fixed to the two driving wheels 6, and the other pulley is fixed to the output end of the first motor 8. When the first motor 8 is working, it drives the driving wheel 6 to rotate through the transmission belt group 12, and the driving wheel 6 moves in the side track 4 when it rotates.

[0049] like Figure 4 As shown, the beam arm assembly also includes a rotation assembly, which includes an assembly plate 9, an inner angle plate 13, a second motor 10, and a drive shaft 14. The assembly plate 9 is fixed to the travel vehicle 5; the inner angle plate 13 is fixed to the inner side of the assembly plate 9; the second motor 10 is fixed to the inner angle plate 13; the drive shaft 14 is rotatably connected to the output end of the second motor 10; and the beam arm plate 11 is fixed to the drive shaft 14. A lower end plate 15 is fixed to the bottom of the assembly plate 9, and the bottom of the drive shaft 14 is rotatably connected to the lower end plate 15. The design of the rotation assembly enables the beam arm plate 11 to rotate through a 90° angle. In specific implementation, the beam arm plate 11 is initially parallel to the side rail 4. During measurement, the second motor 10 operates via the drive shaft 14, driving the beam arm plate 11 to rotate about the drive shaft 14. When the rotation reaches 90°, the second motor 10 stops. At this point, the beam arm plate 11 is perpendicular to the crane 2 and the side rail 4. The detection assembly is located at the bottom of the crane 2. After the measurement is completed, the second motor 10 rotates in the reverse direction, driving the beam arm plate 11 to return to the initial position.

[0050] like Figure 5As shown, the detection assembly includes a vertical end plate 16, a lower plate 25, a guide rail 18, a slider 19, an upper end plate 20, and an elastic assembly 17. The vertical end plate 16 is fixed to the end of the beam arm plate 11; the lower plate 25 is fixed to the beam arm plate 11 and located in front of the vertical end plate 16, and is provided with a transmitter 24. The guide rail 18 is fixed to the vertical end plate 16; the slider 19 is slidably connected to the guide rail 18; the upper end plate 20 is fixed to the slider 19, and the bottom surface of the upper end plate 20 is provided with an upper plate 23, and the bottom surface of the upper plate 23 is provided with a receiver 22, which is arranged corresponding to the transmitter 24. The upper end plate 20 is provided with a guide member, which includes an electric telescopic rod 26 fixed to the upper end plate 20, and a guide roller 21 is provided at the telescopic end of the electric telescopic rod 26. The elastic assembly 17 is provided between the upper end plate 20 and the beam arm plate 11.

[0051] Before testing, the electric telescopic rod 26 is pushed forward, causing the guide roller 21 to contact the bottom surface of the crane 2. As the moving assembly moves along the length of the crane 2, the guide roller 21 rolls against the bottom surface of the crane 2. The guide roller 21 applies pressure to the upper end plate 20 according to the degree of deformation of the crane 2. The upper end plate 20 moves downward or upward in response to the fluctuations of the guide roller 21. As the upper end plate 20 moves, it slides on the guide rail 18 via the slider 19. The elastic component 17 enables the upper end plate 20 to rise. As the detection assembly moves from one end of the crane 2 to the other, the transmitter 24 and receiver 22 transmit and receive signals to detect the curvature of the crane 2. Both the transmitter 24 and receiver 22 are conventional technologies: the transmitter 24 is a laser transmitter, and the receiver 22 is a laser receiving light. The system also includes a wireless signal transmitter, an intelligent monitor, and a display screen. Transmitter 24 emits infrared laser light, while receiver 22 is composed of multiple laser receiving lamps arranged in an array. When the laser receiving lamps receive the infrared light from the laser transmitter, they transmit a signal to the intelligent monitor. The intelligent monitor analyzes the location of receiver 22 and outputs the millimeter ruler data, which is displayed on the display screen. As this technology is existing, we will not elaborate on it here.

[0052] like Figure 6 As shown, the elastic assembly 17 includes a spring 172, the upper and lower ends of which are fixedly connected to the upper end plate 20 and the beam arm plate 11, respectively. It also includes an upper sleeve 171, a bellows 173, and a lower sleeve 174. The upper sleeve 171, the bellows 173, and the lower sleeve 174 are assembled into a single body to form a cavity within which the spring 172 is disposed. The top of the upper sleeve 171 is fixed to the upper end plate 20, and the bottom of the lower sleeve 174 is fixed to the beam arm plate 11. The bellows 173 is connected between the upper sleeve 171 and the lower sleeve 174. When the spring 172 expands and contracts, the bellows 173 expands and contracts accordingly. The upper sleeve 171, the bellows 173, and the lower sleeve 174 form a protective sheath for the spring 172.

[0053] Working principle:

[0054] Step 1: The crane 2 moves to the limiter 3 of the crane travel rail 1 and stops automatically.

[0055] Step 2: The second motor 10 drives the beam arm plate 11 to rotate around the drive shaft 14 through the drive shaft 14. When the second motor 10 rotates 90°, the beam arm plate 11 is vertical to the crane 2 and the side rail 4, and the detection component is located at the bottom of the crane 2.

[0056] Step 3: The electric telescopic rod 26 is pushed forward, causing the guide roller 21 to contact the bottom surface of the crane 2. When the first motor 8 is in operation, it drives the drive wheel 6 via the drive belt assembly 12. The rotation of the drive wheel 6 moves within the side rail 4, causing the beam arm plate 11 and the detection assembly to move. The guide roller 21 applies pressure to the upper end plate 20 according to the degree of deformation of the crane 2. The upper end plate 20 moves downward or upward in response to the fluctuation of the guide roller 21. As the upper end plate 20 moves, it slides on the guide rail 18 via the slider 19. As the detection assembly moves from one end of the crane 2 to the other, the transmitter 24 and receiver 22 send and receive signals to detect the curvature of the crane 2.

[0057] Step 4: The first motor 8 and the second motor 10 rotate in opposite directions to restore the moving assembly and the beam arm plate 11 to their initial positions.

[0058] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
