Description

Technical Field

[0001] The utility model relates to the technical field of prestress detection of steel structures, and particularly relates to a prestress detection device for building steel structures. Background Art

[0002] Building steel is usually divided into steel for steel structures and steel bars for reinforced concrete structures. Among them, steel structures are mainly embodied in the forms of sections, steel pipes, and steel bars. The quality of steel structures determines the stability of the overall building structure. Therefore, before using building steel structures, it is necessary to detect their prestress. As shown in the existing patented technology: After retrieval, the Chinese Patent Network discloses a prestress detection device for building steel structures (publication number CN216207164U). When using such a device, the user pulls up the connecting plate to control the distance between the second sliding plate and the support block, so as to clamp workpieces to be detected with different thicknesses. And the user starts the double-shaft motor through the controller, so that a plurality of threaded rods rotate, and controls the two moving plates to approach each other, so as to clamp workpieces to be detected with different sizes. Then, the detector is controlled by the controller to detect the workpiece to be detected.

[0003] However, for the prestress detection devices for steel structures adopted in the above-mentioned publicly patented technology and the existing market, there are still some deficiencies: The existing method of using manual and electric parallel linkages to fix and detect building steel has relatively high operation risks and is more cumbersome to operate, which is not convenient for flexible and efficient positioning detection of building steel. Therefore, technical personnel in this field provide a prestress detection device for building steel structures to solve the problems raised in the above background art. Summary of the Utility Model

At the top of the shaft of the transmission shaft, a mating gear meshing with the mating rack is provided. On one side of the housing of the transmission housing, an alignment cylinder opposite to the transmission shaft is provided. At the top of the frame of the alignment slider, a support platform is provided. In the middle of the plate seat of the support platform, a support seat is provided, and at the rear end of the plate seat of the support platform, a rotary pressing cylinder is provided.

[0007] As a further solution of the present invention: at the bottom end of the shaft of the transmission shaft, a transmission gear is provided, and at the telescopic end of the alignment cylinder, a transmission rack meshing with the transmission gear is provided.

[0008] As a further solution of the present invention: the two mating racks are symmetrically staggered with respect to the mating gear, and through grooves guiding the mating gear are provided in the frames of the two groups of alignment sliders.

[0009] As a further solution of the present invention: the rotary pressing cylinder is a 90° rotary pressing cylinder structure.

[0010] As a further solution of the present invention: the stress detection assembly includes an arm force plate frame installed at the front end of the vertical bracket. In the middle of the plate seat of the arm force plate frame, a hydraulic cylinder is installed through, and at the telescopic end of the hydraulic cylinder, a pressing table is provided.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] When the present invention conducts the detection work on the prestress of building steel, by using the alignment drive of the alignment cylinder in the support platform assembly, it pushes the support platform to displace and slide symmetrically, pre-adjusts its spacing to adapt to building steel of different lengths, then places the building steel to be detected on the support seat, uses the rotary pressing cylinder to press and position it, and uses the stress detection assembly to conduct the prestress detection work on the positioned building steel. It has good mechanical linkage performance. The staff only needs to pick up and place the building steel. While the operation is simple and convenient, the flexible detection efficiency is higher, and the detection time can be saved. Description of the Drawings

And between the two groups of alignment racks 16, a transmission shaft 18 connected to the transmission shell 3 is installed. At the top of the shaft of the transmission shaft 18, an alignment gear 17 meshing with the alignment rack 16 is provided. On one side of the shell of the transmission shell 3, an alignment cylinder 7 opposite to the transmission shaft 18 is provided. At the bottom of the shaft of the transmission shaft 18, a transmission gear 19 is provided. At the telescopic end of the alignment cylinder 7, a transmission rack 20 meshing with the transmission gear 19 is provided. According to the length of the building steel to be detected, control the telescopic movement of the telescopic end of the alignment cylinder 7 to drive the transmission rack 20 to mesh with the transmission gear 19, convert the horizontal thrust into a rotational thrust, drive the transmission shaft 18 to rotate, and then drive the alignment gear 17 to rotate synchronously as a power source to pre-adjust and align the distance between the support platforms 4.

[0024] The two groups of alignment racks 16 are symmetrically arranged in a staggered manner relative to the alignment gear 17. And through slots guiding the alignment gear 17 are opened in the frames of the two groups of alignment sliders 15. While the alignment gear 17 rotates, by meshing with the alignment racks 16 arranged symmetrically in a front-back staggered manner, the meshing force is converted into a horizontal thrust, driving the two groups of alignment sliders 15 to slide symmetrically along the guide rails of the alignment tracks 14, and then driving the two groups of support platforms 4 to slide symmetrically to pre-adjust and align the distance between the support platforms 4 to adapt to building steels of different lengths.

And at the rear end of the seat plate of the support platform 4, there is a rotary pressing cylinder 6. The rotary pressing cylinder 6 is a 90° rotary pressing cylinder structure. After placing the construction steel to be detected on the support base 5 of the support platform 4, control the rotary pressing cylinder 6 to rotate and press down to tightly press and position the construction steel. And by installing a knob screw at the pressing end of the rotary pressing cylinder 6 in advance, the height of its pressing head can be pre-adjusted to adapt to different construction steel structures.

[0026] At the front end of the bracket of the facade bracket 2, there is a stress detection component. The stress detection component includes an arm force plate frame 9 installed at the front end of the facade bracket 2.

After fixing the construction steel structure, control the telescopic end of the hydraulic cylinder 8 to extend. Under the arm force guiding combination of the guide bushings 12 and the arm force guide rods 13, push the combination of the pressing table 10 and the pressing seat 11 to press down, apply a downward prestress to the construction steel, and conduct the detection work on the prestress of the construction steel.

[0027] The working principle of the present utility model is as follows: When conducting the detection work on the prestress of the construction steel, according to the length of the construction steel to be detected, control the telescopic end of the alignment cylinder 7 to telescopically drive, push the driving rack 20 and the driving gear 19 to engage and drive, convert the horizontal thrust into a rotary thrust, push the transmission shaft 18 to rotate, and then drive the mating gear 17 to rotate synchronously. While the mating gear 17 rotates, utilize the meshing drive with the mating racks 16 arranged symmetrically before and after and staggered, convert the meshing force into a horizontal thrust, push the two alignment slides 15 to slide symmetrically along the guide rail direction of the alignment track 14, and then push the two support platforms 4 to slide symmetrically, pre-adjust and align the distance between the support platforms 4 to adapt to construction steels of different lengths. Then place the construction steel to be detected on the support base 5 of the support platform 4, control the rotary pressing cylinder 6 to rotate and press down to tightly press and position the construction steel. After fixing the construction steel structure, control the telescopic end of the hydraulic cylinder 8 to extend. Under the arm force guiding combination of the guide bushings 12 and the arm force guide rods 13, push the combination of the pressing table 10 and the pressing seat 11 to press down, apply a downward prestress to the construction steel, and conduct the detection work on the prestress of the construction steel. After the detection is completed, the construction steel can be directly taken and placed. Its overall operation is simple, convenient, efficient, and time-consuming is short.
