Multiple dampers 23 are installed between the base 21 and the flat plate 1 and on the inner sides of the two elastic rubber frames 22. The base 21 and the trolley frame 5 are connected through the lifting assembly 24.

[0024] By adopting the above technical solution, the component can buffer the vibration caused by the vibrator 8 to a certain extent through the cooperation of structures such as the elastic rubber frame 22 and the damper 23, thereby reducing the possibility that the vibration caused by the vibrator 8 will cause adverse effects on the surroundings.

[0025] Specifically, the lifting assembly 24 includes a connecting frame 241, a screw rod 242, a lifting block 243 and a knob 244. The connecting frame 241 is installed on the side of the base 21 close to the hand push frame 5, the screw rod 242 is installed at the central position of the connecting frame 241 through a bearing, and the knob 244 is installed below the screw rod 242. The lifting block 243 is installed on the side of the hand push frame 5 close to the connecting frame 241 and located on the inner side of the connecting frame 241 and the outer side of the screw rod 242.

[0026] By adopting the above technical solution, the staff can adjust the height of the hand push frame 5 to a certain extent through the cooperation of the screw rod 242 and the lifting block 243 and other structures when necessary, so as to better meet the habits and needs of different staff members.

[0027] Specifically, the inner side of the connecting frame 241 and the side of the lifting block 243 away from the hand-push frame 5 are in close contact with each other.

[0028] By adopting the above technical solution, the assembly can limit and guide the movement of the lifting block 243 to a certain extent through the connecting frame 241, thereby preventing the lifting block 243 from rotating and deviating during the movement, and ensuring the normal operation.

[0029] When the present embodiment is used, when the staff needs to use the assembly, they turn the knob 244 in the lifting assembly 24 in the buffer lifting device 2, thereby driving the screw rod 242 to rotate. The screw rod 242 is threadedly connected to the lifting block 243, and the lifting block 243 is tightly attached to the connecting frame 241, so the screw rod 242 drives the lifting block 243 and the hand push frame 5 thereon to move until the hand push frame 5 moves to the required height, and then pushes the hand push frame 5 to move the assembly to the working position through each walking wheel 10, and then the staff manipulates each leveling assembly 9 to level the structure such as the plate 1, the staff can judge the horizontal state through the cross level 6, and then pour concrete into each mold 7, start the vibrator 8 to vibrate the concrete, the elastic rubber frame 22 and the damper 23 between the plate 1 and the base 21 can buffer the vibration caused by the vibrator 8, and the staff can install a manual hoist on the lifting assembly 4 when necessary, so as to facilitate the lifting of the prefabricated cover plate after forming, and then work.

[0030] Example 2

[0035] When the present embodiment is used, when it is necessary to close each mold 7, the staff rotates the closing plate 34 in the closing isolation device 3, so that it overcomes the resistance of the two friction rubber rings 33 and rotates around the rotating shaft 32 in the connecting frame 31 until the closing plate 34 covers each mold 7, thereby closing each mold 7, thereby preventing foreign impurities from accidentally entering each mold 7, and ensuring the normal operation.

Its working principle is that the operator observes the cross level, removes the nut, rotates the support cylinder, moves the support cylinder down until it contacts the ground, pads the rubber pad between the support cylinder and the ground, and adjusts the position of the bubble of the cross level according to the bubble position of the cross level. , adjust the support cylinders in each leveling mechanism to level the plate and make the walking wheels leave the ground, and then pour concrete into the mold. After the concrete is formed, move the support cylinder upward to make the walking wheels contact the ground again. When the support cylinder moves to the highest position, install the nuts to fix the support cylinder; push the walking trolley. When the walking trolley moves to the predetermined position, use the manual hoist to lift the prefabricated cover plate in the mold, and then loosen the tightening bolts, rotate the lifting arm, and lift the prefabricated cover plate into the cable trough. At this point, the installation of one prefabricated cover plate is completed. When the next prefabricated cover plate needs to be installed, move this embodiment to the next predetermined position.

[0037] The structure and principle of the damper 23 in the utility model have been disclosed in a smart home washing machine shock absorbing device disclosed in Chinese patent application No. 201721446985.6. Its working principle is composed of a piston and an oil tank, the interior of which is filled with oil. When the object moves, the piston moves in the oil, thereby consuming energy and slowing down the movement of the object.

[0038] The working principle and use process of the utility model are as follows: when the staff needs to use the component, the knob 244 in the lifting component 24 of the buffer lifting device 2 is turned, thereby driving the screw rod 242 to rotate, the screw rod 242 and the lifting block 243 are threadedly connected, and the lifting block 243 and the connecting frame 241 are tightly attached to each other, so the screw rod 242 drives the lifting block 243 and the hand push frame 5 thereon to move until the hand push frame 5 moves to the required height, and then pushes the hand push frame 5, and moves the component to the working position through each walking wheel 10, and then the staff manipulates each leveling component 9 to level the flat plate 1 and other structures, the staff can judge the horizontal state through the cross level 6, and then pour concrete into each mold 7 Concrete, start the vibrator 8 to vibrate the concrete, the elastic rubber frame 22 and the damper 23 between the flat plate 1 and the base 21 can buffer the vibration caused by the vibrator 8, and the staff can install a manual hoist on the lifting assembly 4 when necessary, so as to facilitate the lifting of the prefabricated cover plate after molding, and then carry out work; when it is necessary to close each mold 7, the staff rotates the closing plate 34 in the closing isolation device 3 to overcome the resistance of the two friction rubber rings 33 and rotate around the rotating shaft 32 in the connecting frame 31 until the closing plate 34 covers each mold 7, thereby closing each mold 7, thereby preventing external impurities from accidentally entering each mold 7, and ensuring the normal progress of work.
