[0003] When the existing support device for the jacking construction of municipal road box culverts is used, guide rails are installed on both sides of the receiving well. The guide rails are straight and can only be adjusted in one direction, resulting in low construction accuracy. In addition, the box culvert is suspended into the well by a rope, which makes it easy for the box culvert to rub against the four walls of the receiving well when entering the well, thereby generating greater resistance. In addition, the box culvert collides with the bottom of the well at the moment of reaching the bottom of the well, which can easily cause damage to the box culvert. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4 As shown, the utility model provides the following technical solutions: a support device for jacking construction of a municipal road box culvert, comprising: a support plate 1, a first rotating motor 2 is installed on the support plate 1, the output end of the first rotating motor 2 is connected to a first mounting plate 3, a linear motor 4 is installed on the first mounting plate 3, a first telescopic rod 5 is installed on the output end of the linear motor 4, the output end of the first telescopic rod 5 is connected to a second mounting plate 6, a box culvert body 7 is provided below the second mounting plate 6, a second telescopic rod 8 is installed on the second mounting plate 6, the output end of the second telescopic rod 8 is connected to a fixing plate 9, a suction cup assembly is provided on the fixing plate 9, second rotating motors 13 are installed at the four corners of the lower end surface of the second mounting plate 6, a plurality of second rotating motors 13 are installed at the output ends of the plurality of second rotating motors 13, a bearing plate 15 is installed at the bottom ends of the plurality of connecting plates 14, a movable plate 16 is provided above the bearing plate 15, and the movable plate 16 is located below the box culvert body 7.

[0023] Furthermore, the suction cup assembly includes an air suction cup 10, an air pump 11 and a connecting pipe 12, the air suction cup 10 is installed on the lower end surface of the fixed plate 9, the air pump 11 is installed on the fixed plate 9, and the connecting pipe 12 is installed between the air suction cup 10 and the air pump 11.

[0024] Furthermore, the rolling assembly includes a rolling groove 20 and a ball 21 . The rolling groove 20 is provided on the upper end surface of the movable plate 16 , and the ball 21 is installed in the rolling groove 20 .

[0025] Through the above technical solution:

[0026] When the culvert body 7 is lowered, the culvert body 7 is placed above the movable plate 16. The movable plate 16 and the supporting plate 15 lift the culvert body 7. The second telescopic rod 8 and the vacuum pump 11 are started. The second telescopic rod 8 drives the suction plate 10 to fit the outer wall of the culvert body 7 through the fixed plate 9. The vacuum pump 11 extracts the gas in the suction plate 10 through the connecting pipe 12, so that the suction plate 10 forms a negative pressure, thereby generating a certain suction force on the culvert body 7. When the equipment moves to the top of the receiving well, the first rotary motor 2, the linear motor 4 and the first telescopic rod 5 are started. The first rotary motor 2 and the linear motor 4 are convenient for adjusting the position of the second mounting plate 6 in the x and y directions. The first telescopic rod 5 is convenient for adjusting the position of the second mounting plate 6 in the z direction. After adjusting to a suitable position, the culvert body 7 is lowered into the receiving well. When it reaches the bottom of the receiving well, each second rotary motor 13 is started. The second rotary motor 13 drives the connecting plate 14 to rotate , the connecting plate 14 rotates so that the bearing plate 15 and the movable plate 16 are moved away at the bottom of the culvert body 7, and finally the second telescopic rod 8 and the vacuum pump 11 are started again. The second telescopic rod 8 pushes the culvert body 7 into the installation position, and the vacuum pump 11 controls the suction plate 10 to loosen the culvert body 7, thereby facilitating the evacuation of the entire supporting equipment. When the movable plate 16 rotates, the culvert body 7 is pressed on the top of the movable plate 16, driving the ball 21 to roll in the rolling groove 20, and then the sliding friction between the culvert body 7 and the movable plate 16 is converted into rolling friction, reducing friction and saving effort. By adjusting the x, y, and z directions, it can be ensured that the culvert body 7 always moves along the designed path during the jacking process, avoiding deviation and improving construction accuracy. The jacking method of lifting into the receiving well is adopted, which reduces the jacking distance and can reduce the resistance and friction encountered during the jacking process, thereby reducing the construction difficulty and reducing the requirements for jacking equipment.

[0027] See also Figure 1-Figure 5 As shown, a spring 17 is installed between the bearing plate 15 and the movable plate 16 , a movable assembly is provided between the movable plate 16 and the connecting plate 14 , and a rolling assembly is provided on the upper end surface of the movable plate 16 .

[0028] Furthermore, the movable assembly includes a movable groove 18 and a movable block 19 . The movable groove 18 is provided on the side wall of the connecting plate 14 . The movable block 19 is installed on the side wall of the movable plate 16 . The movable groove 18 and the movable block 19 are adapted to each other.

[0029] Through the above technical solution:

[0030] When the box culvert body 7 is lowered to the bottom of the receiving well, the bearing plate 15 contacts the bottom of the receiving well, the box culvert body 7 presses the movable plate 16 to move up and down, and the spring 17 expands and contracts. At this time, the movable block 19 moves in the movable groove 18, thereby converting part of the kinetic energy into elastic potential energy, reducing the collision force generated when the bottom of the equipment contacts the bottom of the receiving well, thereby protecting the box culvert body 7, reducing the damage caused by the box culvert body 7, and increasing the service life of the equipment.

[0031] For further information, see Figure 1-Figure 2 As shown, a plurality of support columns 22 are installed on the lower end surface of the support plate 1 , and a rolling wheel 23 is installed at the bottom end of each of the plurality of support columns 22 .

[0032] Specifically, the main function of the support column 22 is to provide vertical support force to ensure that the support plate 1 can withstand the weight and pressure from above and remain stable. The rolling wheel 23 allows the support plate 1 to move in the horizontal direction, which is convenient for adjusting the position or moving the entire support plate 1 system when necessary.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
