Description

Technical Field

[0001] This application relates to the field of hoisting equipment technology, and in particular to a truss hoisting device. Background Technology

[0002] A related technology (publication number: CN221370199U) discloses a hoisting device for a steel truss, including a support plate. The support plate has first sliding grooves on its front and rear sides at its bottom. First sliders are slidably connected inside each of the two first sliding grooves. Connecting blocks are provided at the bottom ends of each of the two first sliders, and long plates are provided at the bottom ends of each of the two connecting blocks. Fixed plates are provided on the opposite side of each of the two long plates, and pressure plates are provided on the inner surfaces of each of the two fixed plates. First grooves are provided on adjacent sides of each of the two long plates. Electric push rods are installed in each of the two first grooves. Connecting plates are fixedly connected to the bottom ends of the telescopic ends of each of the two electric push rods, and clamping plates are provided at the bottom ends of each of the two connecting plates. The clamping plates are connected to the fixed plates via threaded rods.

[0003] In the process of implementing the technical solution disclosed herein, it was found that the above technical solution has at least the following problems:

[0004] The hoisting device for this steel truss operates by extending the moving ends of two electric push rods, causing two connecting plates to extend downwards. Workers then use this extension gap to place the steel truss onto the two clamping plates. Retracting the moving ends of the two electric push rods moves the steel truss upwards until it contacts the pressure plate, thus securing it. However, even after the connecting plates extend downwards to create a gap, the positions of the two first sliders or the steel truss itself still need to be adjusted before it can be placed onto the clamping plates, making the operation somewhat cumbersome.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0018] The truss hoisting device provided in this disclosure can achieve the following technical effects:

[0019] This disclosure provides a truss hoisting device, comprising a first support plate, linear slides, second support plates, third support plates, a first cylinder, a first clamping plate, a second cylinder, and a second clamping plate. The linear slides are respectively installed at the four corners of the bottom surface of the first support plate along its length, providing driving force to move along the length of the first support plate. The second support plates are respectively installed at the moving ends of the four corner linear slides, moving along the length of the first support plate under the drive of the four corner linear slides. The third support plates are rotatably installed on the four corner second support plates, forming an included angle between the second and third support plates at the same angle. The second and third support plates at the same angle can rotate relative to each other to change the angle value. The first cylinders are rotatably installed between the four corner second and third support plates, and the four corner first cylinders can rotate relative to the four corner second and third support plates respectively, configured to change the included angle value of the four corners. The first clamping plates are connected to the third support plates at each of the four corners, and are used to abut against the steel truss. Second cylinders are installed on the third support plates at each of the four corners, and are used to provide driving force to clamp or release the steel truss. The second clamping plates are installed on the moving ends of the second cylinders at the four corners, and are moved closer to or further away from the first clamping plates under the action of the second cylinders. Specifically, under the action of the second cylinders at the four corners, the second clamping plates at the four corners can abut against the first clamping plates at the four corners.

[0020] During operation, the first support plate connects to the hook of the lifting device, allowing the entire device to move under the influence of the lifting device, ultimately completing the lifting operation. In use, controlling the four corner linear slides moves the four corner second support plates along the length of the first support plate, adjusting the positions of the four corner first and second clamping plates to suit different steel trusses. Retracting the moving end of the four corner first cylinder rotates the four corner third support plate relative to the four corner second support plates, ultimately positioning the four corner first clamping plates diagonally below the four corner second clamping plates. At this point, under the influence of the lifting device, the two side first clamping plates are positioned diagonally below the steel truss, and the two side second clamping plates are positioned diagonally above the steel truss. Then, extending the moving end of the four corner first cylinder rotates the four corner third support plate relative to the four corner second support plates, ultimately positioning the four corner second clamping plates directly above the four corner first clamping plates, and placing the four corner first and four corner second clamping plates directly below and above the steel truss, respectively. Then, by controlling the operation of the second cylinders at the four corners, the second clamping plates at the four corners gradually move closer to the first clamping plates at the four corners, ultimately clamping and fixing the steel truss. Then, under the control of the lifting device, the clamped and fixed steel truss can be moved, ensuring the stability of the steel truss during lifting. Furthermore, during the clamping and fixing process, there is no need to repeatedly adjust the position of the second support plates at the four corners or the steel truss, facilitating the fixation of the steel truss.
