[0002] As a key facility to ensure the stable operation of electronic equipment and the safety of personnel, anti-static raised floor is increasingly widely used. Whether it is a large server room, a precision electronic instrument production workshop, or a core data processing center of a financial institution, anti-static raised floor has important functions such as releasing static electricity and bearing the weight of equipment. Therefore, it is particularly important to conduct quality inspection of anti-static raised floor before it leaves the market, and it is usually necessary to conduct concentrated load test on it.

[0003] However, the existing concentrated load test device may cause the anti-static raised floor to move during testing, causing the anti-static raised floor to fall, resulting in a large deviation in the test results and affecting the efficiency of the anti-static raised floor test. Summary of the invention

[0004] The technical problem to be solved by the present invention is: to provide a concentrated load test device, which, by setting a fixing mechanism, solves the problem that the concentrated load test device may cause the anti-static movable floor to move during detection, causing the anti-static movable floor to fall, resulting in a large deviation in the detection result and affecting the efficiency of the anti-static movable floor detection.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a concentrated load test device, comprising a bracket, wherein the bracket is provided with a fixing mechanism and a moving mechanism; The fixing mechanism includes a motor bracket fixedly connected to the bottom of the bracket, the inner wall of the motor bracket is fixedly connected to motor 1, the output shaft of motor 1 is fixedly connected to rotating shaft 1 through a coupling, the top of rotating shaft 1 passes through the bracket and extends to the outside, rotating shaft 1 is rotatably connected to the bracket, four rectangular blocks are fixedly connected to the top of the bracket, the four rectangular blocks are respectively arranged at the two ends of two large sliding rods, that is, a large sliding rod is fixedly connected between the two rectangular blocks, and the moving mechanism includes a U-shaped bracket fixedly connected to the top of the bracket, the top of the U-shaped bracket is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected to a slider.

[0006] Furthermore, two movable plates are slidably connected to the two large sliding bars, two small sliding bars are passed through each movable plate, each small sliding bar is slidably connected to the movable plate respectively, and a fixed plate is fixedly connected to one side of the four small sliding bars close to each other.

[0007] Furthermore, each of the small sliding rods is sleeved with a spring, and the sides of the springs that are close to each other are fixedly connected to the two fixed plates respectively, and the sides of the springs that are away from each other are fixedly connected to the two movable plates respectively.

[0008] Furthermore, a buffer pad is fixedly connected to one side of the two fixing plates close to each other, a bidirectional hinged rod is fixedly connected to the outer wall of the rotating shaft 1, and a hinged rod is hingedly provided on the front and rear sides of the bidirectional hinged rod.

[0009] Furthermore, the bottoms of the two movable plates are fixedly connected with fixed rods, and the sides of the two hinged rods that are away from each other are hinged to the two fixed rods respectively.

[0010] Furthermore, the bottom of the slider is fixedly connected to a hydraulic cylinder, the bottom of the hydraulic cylinder is fixedly connected to an extrusion plate, the hydraulic cylinder is fixedly connected to a pressure gauge, the top of the slider is fixedly connected to a rack, the top of the U-shaped bracket is fixedly connected to motor 2, and the top of the U-shaped bracket is fixedly connected to a rectangular plate.

[0011] Furthermore, the output shaft of the second motor is fixedly connected to the second rotating shaft through a coupling, the side of the second rotating shaft away from the second motor passes through the rectangular plate and extends to the outside, the outer wall of the second rotating shaft is fixedly connected to a gear, and the gear is meshed with the rack.

[0012] The beneficial effects of the present invention are that the defects existing in the background technology are solved. 1. By setting a fixing mechanism, the anti-static movable floor is placed on two movable plates, and then the motor 1 is started. The motor 1 drives the two-way hinged rod to rotate clockwise through the rotating shaft 1. When the two-way hinged rod rotates, the two hinged rods are driven to move to reduce the angle between the hinged rod and the two-way hinged rod, so that the two hinged rods pull the two movable plates to slide on the two large sliding rods and approach each other through the two fixed rods, thereby fixing the anti-static movable floor. When the anti-static movable floor is fixed, the anti-static movable floor contacts the buffer pad and squeezes the fixed plate through the buffer pad. At this time, the two fixed plates move away from each other and squeeze the small sliding rod and the spring, so that the spring generates elastic force. The spring elastic force will push the two fixed plates to fix the anti-static movable floor. The buffer pad can prevent the anti-static movable floor from being damaged when it is fixed, so as to prevent the anti-static movable floor from falling off the test device due to being unable to withstand the load, thereby avoiding damage to the test equipment and personnel, and preventing the anti-static movable floor from unnecessary translation or rotation due to the load, thereby ensuring the reliability of the test data; 2. By setting up a moving mechanism, start motor 2 to adjust the position of the anti-static movable floor detection. Motor 2 drives the gear to rotate clockwise through shaft 2. When the gear rotates, the slider is driven to move left in the slide groove through the rack, thereby adjusting the position of the hydraulic cylinder and the extrusion plate to detect the anti-static movable floor. When motor 2 drives the gear to rotate counterclockwise through shaft 2, the hydraulic cylinder is driven to move right through a movement process opposite to the above, thereby adjusting the position of the hydraulic cylinder, so that the application position of the concentrated load can be changed arbitrarily within a certain range to meet the needs of the anti-static movable floor and test conditions, and the load can be moved to the required position quickly and accurately, reducing the preparation time and adjustment workload before the test.

[0017] A specific application of this embodiment is: when in use, the anti-static movable floor is placed between the two movable plates 216, and then the motor 1 212 is started. The motor 1 212 drives the two-way hinged rod 2111 to rotate clockwise through the rotating shaft 1 213. When the two-way hinged rod 2111 rotates, it drives the two hinged rods 2112 to move to reduce the angle between the hinged rod 2112 and the two-way hinged rod 2111, so that the two hinged rods 2112 pull the two movable plates 216 on the two large sliding rods 215 through the two fixed rods 2113 to slide and approach each other, thereby fixing the anti-static movable floor. When the anti-static movable floor is fixed, the anti-static movable floor contacts the buffer pad 2110 and squeezes the fixed plate 218 through the buffer pad 2110.

When the gear 3111 rotates, the slider 313 is driven to move left in the slide groove 312 through the rack 317, thereby adjusting the position of the hydraulic cylinder 314 and the extrusion plate 315, and the anti-static movable floor is detected. When the motor 2 318 drives the gear 3111 to rotate counterclockwise through the rotating shaft 2 3110, the hydraulic cylinder 314 is driven to move right through the opposite movement process to the above, thereby adjusting the position of the hydraulic cylinder 314, and then the hydraulic cylinder 314 is started. The output rod of the hydraulic cylinder 314 drives the extrusion plate 315 to pressurize the anti-static movable floor, and the value of the pressure gauge 316 is observed to determine the load that the anti-static movable floor can withstand.
