[0033] Example: Figures 1-7 As shown, the intelligent rapid installation device for the bridge spherical hinge base in this embodiment is used to quickly install the spherical hinge base used for bridge rotation, ensuring the installation accuracy of the spherical hinge base and thus ensuring the installation accuracy of the rotating spherical hinge.

[0034] Specifically, as shown in the figure, the device in this embodiment is composed of three parts: electric jacking screw 1, unpowered rolling device 2 and center positioning base 3. Figure 4

[0035] Among them, as shown in the figure, the electric jacking screw 1 mainly includes a driving motor 1-1 and a driving gear 1-2. The driving motor 1-1 is the prime mover of the electric jacking screw 1 for providing jacking power, and the driving gear 1-2 is in transmission connection with the driving motor 1-1 to drive the screw below to lift and adjust the height. Figure 1

[0036] As shown in the figure, the unpowered rolling device 2 includes auxiliary rollers 2-1 and rolling steel balls 2-2. Among them, two auxiliary rollers 2-1 are respectively extended on both sides of the main body of the unpowered rolling device 2, and the two auxiliary rollers 2-1 are symmetrically distributed. The rolling steel balls 2-2 are embedded at the bottom of the main body of the unpowered rolling device 2, and part of the rolling steel balls 2-2 are exposed outside the bottom of the main body of the unpowered rolling device 2, so that the bottom of the unpowered rolling device 2 is actually a rollable spherical surface. Figure 2 Figure 2 Figure 4 As shown in the figure, the top of the main body of the unpowered rolling device 2 is a socket type mounting groove, and the shape and size of the groove body of the mounting groove are matched with the outer contour shape and size of the bottom connecting section of the electric jacking screw 1, so that the electric jacking screw 1 can be inserted into the main body of the unpowered rolling device 2 to form a limiting connection between them.

[0037] As shown in the figure, the center positioning base 3 includes a disc-shaped main body structure, and self-limiting structures matched with the auxiliary rollers 2-1 and the rolling steel balls 2-2 of the unpowered rolling device 2 are respectively arranged on the main body structure. Figure 3 Two auxiliary roller slides 3-3 are formed in one-to-one correspondence with the two auxiliary rollers 2-1 respectively, and the two auxiliary roller slides 3-3 are gradually extended downward from the top surface of the center positioning base 3 to form slides along the disc-shaped main body structure, and auxiliary roller positioning grooves 3-4 are respectively arranged at the end of the two auxiliary roller slides 3-3, and the shape and size of the auxiliary roller positioning grooves 3-4 are matched with the outer contour shape and size of the auxiliary rollers 2-1; when the auxiliary rollers 2-1 slide downward along the auxiliary roller slides 3-3 and are clamped in the auxiliary roller positioning grooves 3-4 to form a limiting connection.

[0038]

[0039] ​​​​​The matching rolling steel ball 2-2 is the rolling steel ball positioning groove 3-1 and the rolling steel ball sliding surface 3-2, which is the inner wall surface of the disc-shaped main body structure and has a certain slope; in some cases, the bottom surface of the disc pile structure main body can also be provided with a certain slope; when the rolling steel ball 2-2 can gradually roll into the steel ball positioning groove 3-1 under the sliding guidance of the rolling steel ball sliding surface 3-2 and form a limiting embedding.

[0040] At this time, the self-guiding between the unpowered rolling device 2 and the center positioning base 3 can be realized by the self-guiding between the auxiliary roller 2-1 and the auxiliary roller slide 3-3 and the self-guiding between the rolling steel ball 2-2 and the rolling steel ball sliding surface 3-2; at the same time, the self-limiting between the unpowered rolling device 2 and the center positioning base 3 after the self-guiding can be realized by the limiting between the auxiliary roller 2-1 and the auxiliary roller positioning groove 3-4 and the limiting between the rolling steel ball 2-2 and the rolling steel ball positioning groove 3-1, which improves the relative position accuracy between the two and further facilitates the construction and improves the installation efficiency.

[0041] As shown in Figure 3 , four base fixing supports 3-5 are symmetrically arranged around the center positioning base 3 with their centers as the center, and each base fixing support 3-5 is used for the installation and fixation of the center positioning base 3 itself. In this embodiment, two fixing supports 3-5 are arranged at positions corresponding to the auxiliary roller positioning groove 3-4 to stably support the positions and ensure that the auxiliary roller 2-1 can be stably and firmly clamped in the auxiliary roller positioning 3-4.

[0042] Combined with Figures 5-7 , when the ball hinge base 7 is installed by using the ball hinge base 7 of the bridge swivel ball hinge base intelligent rapid installation device in this embodiment, the bottom of the ball hinge base 7 has an auxiliary support 6 arranged in a cross shape below the ball hinge base 7 to ensure the installation strength of the ball hinge base 7 and facilitate positioning. The installation method of this embodiment specifically includes the following processes:

[0043] 1) Position the center position of the ball hinge base 7, and position and fix the center positioning base 3 at the center position. Specifically, when the center positioning base 3 is positioned and fixed, the connecting line direction of the two auxiliary roller positioning grooves 3-4 is parallel to any one side of the designed installation position of the ball hinge base 7.

[0044] As shown in Figure 5 , the center positioning base 3 is the base part of the center jacking and positioning device 4.

[0045] 2) Install electric jacking screw 1 at the position of the supporting point of auxiliary support 6 and the center position respectively, and install non-powered rolling device 2 at the bottom of electric jacking screw 1 at the center position, and complete the whole support which can be leveled.

[0046] 3) Hoist the whole support above the center positioning base 3 and align non-powered rolling device 2 at the center position with center positioning base 3;

[0047] 4) Lower the whole support, in the process, rolling steel ball 2-2 of non-powered rolling device 2 is embedded in rolling steel ball positioning groove 3-1 under the sliding guidance of rolling steel ball sliding surface 3-2, and auxiliary roller 2-1 is clamped into auxiliary roller positioning groove 3-4 under the rolling guidance of auxiliary roller sliding way 3-3, and the direction of ball hinge base 7 side of the whole device is guided to be consistent with the designed direction, that is, the automatic adjustment of the installation direction of ball hinge base 7 is realized.

[0048] 5) Install high-precision inclinometer 5 on auxiliary support 6 and configure control computer 8, and the signal interaction is formed between control computer 8 and high-precision inclinometer 5, high-precision inclinometer 5 is used to measure the inclination of auxiliary support 6, and then feedback the position of ball hinge base 7 above it; control computer 8 can control the stroke of each electric jacking screw 1 according to the measurement data of high-precision inclinometer 5 and using the algorithm programmed by it, so as to adjust ball hinge base 7 to be horizontal.

[0049] 6) After completion, weld steel support on each side of ball hinge base 7 to fix the whole ball hinge base 7, and then disassemble all devices except ball hinge base 7.

[0050] In the whole installation process, the main functions realized by non-powered rolling device 2 and center positioning base 3 are two, one is to limit the horizontal direction of ball hinge base 7 in the installation process by using the weight of ball hinge base 7 and its auxiliary support 6 at the supporting point position, so that ball hinge base 7 only needs to be adjusted to be horizontal in the height direction in the subsequent adjustment process, avoiding repeated adjustment and mutual influence between the two position adjustments; the other is to realize the self-guiding adjustment of the installation direction of ball hinge base 7, which is convenient for the construction personnel at the construction site to position the subsequently installed ball hinge base 7 when installing the smaller center positioning base 3, rather than positioning the ball hinge base 7 in the installation process, so it is a kind of "preposition" of ball hinge base 7 positioning, which is significantly convenient for construction.

[0051] Although the above embodiments have been described in detail with reference to the accompanying drawings for the purpose of illustrating the concepts and embodiments of the present application, those skilled in the art can recognize that various improvements and changes can be made to the present application without departing from the scope defined by the claims, therefore, they are not described here.
