[0027] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] A shear force detection device is a device used to detect how much shear force an object can withstand. It is often used in the construction field. When in use, the existing load-bearing beam shear force detection device uses a cutter to perform a shear force test on a fixed load-bearing beam. However, when performing a shear force test, the existing device can only detect a single force point on the load-bearing beam. The test result is accidental, resulting in inaccurate test results and causing safety hazards.

[0029] The purpose of this embodiment is to provide a shear force detection device for a building load-bearing beam, such as Figure 1-4 As shown, it includes a frame 100, a cylinder 103 is provided at the bottom of the frame 100, a support plate 102 is provided at the top of the cylinder 103, fixing holes 107 are provided on the surface of the support plate 102, and the fixing holes 107 are arranged in a circular array. The piston rod at the end of the cylinder 103 drives the support plate 102 to move in a vertical direction, a rotating disk 106 is provided at the top of the support plate 102, and a cutter 104 is provided on the surface of the rotating disk 106. The cutter 104 is used to apply shear force to the load-bearing beam, and symmetrical adjustment and fixing components 300 are provided on both sides of the rotating disk 106. The adjustment and fixing components 300 are used to adjust the shear force direction of the fixed cutter 104. A first motor 105 is provided at the top of the frame 100, and the output end of the first motor 105 passes through the frame 100 and a driving gear is provided at the end. A clamping component 200 is provided below the driving gear. The clamping component 200 is used to clamp and fix the load-bearing beam, and a shear beam sensor is provided below the clamping component 200.

[0030] The improvement of this embodiment lies in that: by rotating the rotating disk 106 to adjust to the shear direction to be tested, the fixed column 301 is adapted to the fixing hole 107 by the force of the elastic member 302, so that the angle of the cutter 104 is fixed, and the adjusted cutter 104 is fixed by adjusting the fixing component 300. By adjusting the shear angle of the cutter 104 multiple times, different force points of the load-bearing beam are tested, so as to obtain accurate data on the shear force that the load-bearing beam can withstand, thereby improving the safety of the load-bearing beam.

[0031] When performing shear force detection on the load-bearing beam, in order to improve the accuracy of the shear force test on the load-bearing beam, it is necessary to detect different force points of the load-bearing beam, so as to obtain accurate shear force bearing data. Therefore, the adjustment and fixing component 300 includes fixed columns 301 arranged on both sides of the top of the rotating disk 106, the fixed columns 301 are adapted to the fixing holes 107, and a top plate is provided on the top of the fixed columns 301, and elastic members 302 are provided on the top plate and the top of the rotating disk 106. By rotating the rotating disk 106, the rotating disk 106 is made to perform a circular motion on the surface of the support plate 102. By rotating the rotating disk 106 to adjust to the shear direction to be tested, the fixed columns 301 are adapted to the fixing holes 107 by the force of the elastic member 302, so as to fix the angle of the cutter 104. By adjusting the shear angle of the cutter 104 multiple times, accurate data on the shear force that the load-bearing beam can withstand is obtained.

[0032] When performing shear force tests on the load-bearing beam in different directions, it is necessary to rotate the rotating disk 106 multiple times. Therefore, symmetrical auxiliary arms 303 are provided on both sides of the fixed column 301. The auxiliary arms 303 pass through the top of the rotating disk 106. The surface of the auxiliary arms 303 is provided with threads, and the position of the auxiliary arms 303 is fixed by bolts. The operator pulls the fixed column 301 to make its ends away from the fixing holes 107. The auxiliary arms 303 provided on both sides of the fixed column 301 pass through the inside of the rotating disk 106, and the position of the rotating disk 106 is fixed by bolts, thereby facilitating the rotation and adjustment of the rotating disk 106 and facilitating independent operation of the operator.

[0033] Taking into account the heavy weight of the cutter 104, in order to reduce the labor intensity of the operators, a servo motor 400 is provided at the bottom of the support plate 102, and a first transmission wheel is provided at the output end of the servo motor 400, and a second transmission wheel is provided on the surface of the rotating disk 106. The first transmission wheel and the second transmission wheel are transmitted through a transmission belt 401, and the second transmission wheel is driven to rotate by the transmission belt 401 to adjust the angle of the rotating disk 106. The first transmission wheel is driven to rotate by the output shaft of the servo motor 400, and the first transmission wheel drives the second transmission wheel to rotate through the transmission belt 401, so that the rotating disk 106 rotates on the surface of the support plate 102, and the shearing angle of the cutter 104 is automatically adjusted by controlling the rotation of the output shaft of the servo motor 400, thereby reducing the labor intensity of the operators.

[0034] In order to facilitate the rapid clamping and fixing of the load-bearing beam, the clamping assembly 200 includes driven gears 201 arranged on both sides below the driving gear, and screw rods 202 are arranged at the ends of the driven gears 201. Clamp plates 203 are arranged on the surface of the screw rods 202. The driving gear is rotated to drive the screw rods 202 to rotate so that the clamp plates 203 move relatively. The output shaft of the first motor 105 drives the driving gear to rotate, and the driven gears 201 arranged on both sides of the driving gear are meshed and rotated. The screw rods 202 arranged on both sides of the driven gear 201 rotate, so that the clamp plates 203 arranged on the surface of the screw rods 202 move relatively. The load-bearing beam is clamped and fixed, and when the angle of the rotating disk 106 is adjusted to a suitable position by the transmission belt 401, the cutter 104 whose angle is adjusted is fixed by adjusting the fixing assembly 300, and the support plate 102 is pushed by the cylinder 103 to enable the cutter 104 to detect the shear force of the load-bearing beam. The position where the load-bearing beam contacts the cutter 104 is fractured, and the fractured portion of the load-bearing beam is tilted in a triangular shape, so that the fractured portion of the load-bearing beam contacts the bottom of the shear beam sensor, thereby realizing the shear force detection of multiple force points of the load-bearing beam, thereby improving the accuracy of the shear force detection.

[0035] Taking into account that the support plate 102 is prone to shifting when moving, the side walls of the frame 100 are provided with symmetrical limit grooves 101, and the side walls of the support plate 102 are provided with limit blocks. When the support plate 102 moves, the limit blocks slide on the inner walls of the limit grooves 101, and when the support plate 102 moves, the limit blocks slide on the inner walls of the limit grooves 101, thereby limiting the support plate 102 during the movement process and improving the stability of the support plate 102 when moving.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
