[0032] Furthermore, the lifting assembly includes: A turntable 7 is rotatably mounted on top of the support frame 6; The second motor 37 is fixed to the support frame 6, and the output shaft of the second motor 37 is fixed to the turntable 7; A first support 12, the first support 12 is fixed on the top of the turntable 7; A first hydraulic push rod 13, the first hydraulic push rod 13 is rotatably connected to the first support 12; A hydraulic winch 14 is fixed to the telescopic end of the first hydraulic push rod 13; A steel cable 15, one end of which is fixed to the reel of the hydraulic winch 14, and the other end of which is fixed to a third electromagnet 40; Support base 18, support base 18 is fixed on the side wall of turntable 7; A second support 19, the second support 19 is fixed on the top of the support base 18; The second hydraulic push rod 20 is rotatably connected to the second support 19 , and the telescopic end of the second hydraulic push rod 20 is rotatably connected to the first hydraulic push rod 13 .

[0033] The turntable 7 is driven to rotate by the second motor 37 to adjust the horizontal position of the hydraulic winch 14 at the end of the first hydraulic push rod 13. The second hydraulic push rod 20 cooperates with the rotation of the two second supports 19 to adjust the inclination angle of the first hydraulic push rod 13 to achieve height adjustment of the hydraulic winch 14. The hydraulic winch 14 works and the switch of the third electromagnet 40 is turned on to achieve the rise of the first counterweight 16. When the first counterweight 16 rises to the hydraulic winch 14, the switch of the third electromagnet 40 is turned off to achieve the release of the first counterweight 16. The first counterweight 16 is used to impact the door panel of the civil defense door to perform dynamic load testing of the door panel of the civil defense door.

[0034] Furthermore, the counterweight assembly includes: A second counterweight 41 is provided with a connecting seat 45 fixed to the side wall of the second counterweight 41 , and the connecting seat 45 is adapted to fit in the rectangular hole 44 ; A first magnet 42 is fixed on the top of the second counterweight 41; The card slot 49 is provided at the bottom of the connecting seat 45; A first groove 50 is provided in the first counterweight 16 , the first groove 50 is connected to the rectangular hole 44 , and a second groove 51 is provided at the bottom of the first groove 50 ; The second magnet 43 is slidably disposed in the first groove 50 , and a plurality of fixing rods 48 are disposed at the bottom of the second magnet 43 ; The connecting frame 47 is fixed to a plurality of fixing rods 48 , and a clamping block 46 is fixed on each of the four sides of the connecting frame 47 , and the clamping block 46 is adapted to the clamping slot 49 .

[0035] When the first counterweight 16 reaches its highest point and still cannot perform an effective impact test, the second counterweight 41 can be lifted by the action of the third electromagnet 40 and the first magnet 42, and the connecting seat 45 on the second counterweight 41 is inserted into the corresponding rectangular hole 44 on the first counterweight 16. Then, the third electromagnet 40 and the first magnet 42 are released. Thereafter, the first counterweight 16 and the second counterweight 41 are temporarily fixed together under the action of the connecting seat 45 and the rectangular hole 44. After an appropriate number of second counterweights 41 and the first counterweight 16 are preliminarily fixed, the third electromagnet 40 is moved to the top of the first counterweight 16, and the switch of the third electromagnet 40 is turned on. When the third electromagnet 40 is working, it attracts the second magnet 43. During the rising process of the second magnet 43, the connecting frame 47 is driven to rise through the fixing rod 48, and then all the blocks 46 are driven to rise. When the blocks 46 enter the card slots 49, the final fixation between the connecting seat 45 and the first counterweight 16 can be achieved, and then the overall weight of the first counterweight 16 is increased by adding the second counterweight 41, thereby increasing the impact force.

[0036] The specific working method is: first, the auxiliary pulley needs to be installed, and the installation position of the auxiliary pulley needs to be determined according to the position of the guide rail 5, and then the first connecting rope 11 and the second connecting rope 21 are tensioned and adjusted in direction through the action of the auxiliary pulley; During the frontal impact test, the turntable 7 is driven to rotate by the second motor 37 to adjust the horizontal position of the hydraulic winch 14 at the end of the first hydraulic push rod 13. The second hydraulic push rod 20 cooperates with the rotation of the two second supports 19 to adjust the inclination angle of the first hydraulic push rod 13 to achieve height adjustment of the hydraulic winch 14. The hydraulic winch 14 works to turn on the switch of the third electromagnet 40 to achieve the rise of the first counterweight 16. When the first counterweight 16 rises to the hydraulic winch 14, the switch of the third electromagnet 40 is turned off to release the first counterweight 16. The first counterweight 16 is used to impact the door panel of the civil air defense door to perform the dynamic load test of the door panel of the civil air defense door. During this process, the position adjustment of the two mounting plates 27 is achieved through the operation of the electric push rod 38 in cooperation with the connecting plate 39, so that the first motor 28 on the mounting plate 27 drives the first bevel gear 29 to engage with the two second bevel gears 30 respectively. The operation of the first motor 28 cooperates with the action of the first motor 28 and the second bevel gear 30 to drive the corresponding screw rod 32 to rotate, thereby driving the connecting block 33 to move. The baffle 4 is able to rotate around the ear plate 3 through the action of the connecting rod 34. Through the above operation, the two baffles 4 are adjusted to a vertical state, so that the door panel of the civil air defense door remains stable during the dynamic load test. In addition, according to actual conditions, the impact plates 17 and the first counterweight 16 with different surface areas can be fixed to achieve dynamic load testing under different contact areas; When performing the door frame impact test, the second motor 37 drives the turntable 7 to rotate so that the first counterweight 16 is located at one side of the support frame 6, and the steel cable 15 is released by the hydraulic winch 14 to make the first counterweight 16 at the lowest position, and the switch of the second electromagnet 22 is turned on so that the second electromagnet 22 can be adsorbed on the first counterweight 16, and then the first counterweight 16 is driven to rise by the operation of the hydraulic winch 14. In this process, the first counterweight 16 drives the second connecting rope 21 to move through the second electromagnet 22, and the second connecting rope 21 drives the fixed plate 35 to move along the guide rail 5 through the transmission block 36, so that the trolley 25 can move to the end of the guide rail 5, then turn off the switch of the second electromagnet 22, and control the first counterweight 16 to continue to rise until the first counterweight 16 moves to the first electromagnet 10, then turn on the switch of the first electromagnet 10, and the first electromagnet 10 is adsorbed on the first counterweight 16 when working, and then turn off the switch of the third electromagnet 40 to make the first counterweight 16 vertically descend, and the first electromagnet 10 drives the first connecting rope 11 to move, and through the action of each auxiliary pulley, the first connecting rope 11 can drive the trolley 25 to move along the guide rail 5 through the transmission block 36 and the fixed plate 35, and hit the door frame of the civil air defense door; Before the above test, the position of the first bevel gear 29 should be adjusted so that the first bevel gear 29 is meshed with the corresponding second bevel gear 30, and the baffle 4 on the side of the door frame that is hit is rotated to an inclined state through the operation of the first motor 28 in cooperation with the screw rod 32, the connecting block 33 and the connecting rod 34 to prevent the trolley 25 from hitting the baffle 4. The baffle 4 on the other side in the vertical state can provide support for the civil air defense door, thereby avoiding energy loss caused by displacement of the civil air defense door after being hit, so as to ensure the test accuracy; In addition, during the impact process, by removing or increasing the number of impact blocks 26, testing work with different contact areas and different contact positions can be achieved; When the first counterweight 16 reaches its highest point and still cannot perform an effective impact test, the second counterweight 41 can be lifted by the action of the third electromagnet 40 and the first magnet 42, and the connecting seat 45 on the second counterweight 41 is inserted into the corresponding rectangular hole 44 on the first counterweight 16. Then, the third electromagnet 40 and the first magnet 42 are released. Thereafter, the first counterweight 16 and the second counterweight 41 are temporarily fixed together under the action of the connecting seat 45 and the rectangular hole 44. After an appropriate number of second counterweights 41 and the first counterweight 16 are preliminarily fixed, the third electromagnet 40 is moved to the top of the first counterweight 16, and the switch of the third electromagnet 40 is turned on. When the third electromagnet 40 is working, it attracts the second magnet 43. During the rising process of the second magnet 43, the connecting frame 47 is driven to rise through the fixing rod 48, and then all the blocks 46 are driven to rise. When the blocks 46 enter the card slots 49, the final fixation between the connecting seat 45 and the first counterweight 16 can be achieved, and then the overall weight of the first counterweight 16 is increased by adding the second counterweight 41, thereby increasing the impact force.

[0037] It is worth mentioning that the auxiliary pulley mentioned in the present application is mainly used to adjust the direction of the first connecting rope 11 and the second connecting rope 21 to ensure that the force applied to the trolley 25 is parallel to the guide rail 5.
