During the operation process, some coating damage inevitably occurs and needs to be repaired. At that time, the life of the anti-corrosion coating of general steel bridges was about 20 years. At present, a large number of steel bridge coatings will gradually enter the renovation stage.

Parts of the six blade plates 24 extend to the bottom of the shell 23 and enclose a hexagonal space that can be enclosed around the corresponding bolt, and the six blade plates 24 can adjust the size of the formed hexagonal space by relative adjustment; a glue injection mechanism is arranged on the mounting frame 41, and the glue injection mechanism is used to inject glue into the hexagonal space to achieve corrosion protection of the bolts.

The hexagonal space formed by the six blade plates on the shell can be buckled on the nut at the end of the bolt. The hexagonal space defines the glue injection range. The glue injection mechanism can inject glue into the corresponding hexagonal space to complete the anti-corrosion maintenance of the bolt. The device of the utility model is particularly suitable for maintaining the bolt group on the steel bridge. It can realize the automatic completion of the bolt glue coating operation, which can improve the work efficiency and can also shape the glue to make the appearance beautiful.

[0067] In a specific embodiment of the present invention, Figures 1 to 3As shown, a damping rail 45 is provided on the top of the mounting frame 41, and a first rotating mechanism 46 is connected to the top of the damping rail 45.

[0068] The strip frame 43 at the front end is connected to the positioning mechanism 47, and the other strip frames 43 are connected to the shell 23. Since each strip frame 43 is slidably arranged on the mounting frame 41 in the horizontal direction, the positioning mechanism 47 and each shell 23 are arranged on the same straight line. After the glue coating device of the utility model is placed above the bolt, the positioning mechanism 47 can be adjusted by moving downward so that the positioning plate 471 of the positioning mechanism 47 contacts the mounting surface of the bolt (the mounting surface can be a steel bridge deck), and then a pair of positioning plates 471 are moved toward each other to adjust and clamp at least two bolts on the same row. During the clamping process, the angle and position of the mounting frame 41 are adjusted by the rotation adjustment of the first rotating mechanism 46 and the movement adjustment of the damping slide rail 45, so that the shell 23 corresponds to the position of the bolt. Initially, the spacing between the pair of positioning plates 471 can be smaller than the spacing between the two rows of bolts, so that when the positioning plates 471 are moved downward to adjust, the positioning plates 471 can be located on both sides of a row of bolts.

[0069] Furthermore, if Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the positioning mechanism 47 includes a first telescopic driving member 473 connected to the corresponding strip frame 43 and a bidirectional telescopic driving member 474 provided at the bottom of the first telescopic driving member 473; the first telescopic driving member 473 can drive the bidirectional telescopic driving member 474 to perform lifting and lowering adjustment; the driving end of the bidirectional telescopic driving member 474 is connected to the corresponding positioning plate 471, and can drive a pair of positioning plates 471 to move synchronously toward each other or move synchronously in the opposite direction. The first telescopic driving member 473 is preferably an electric cylinder, a pneumatic cylinder or a push rod motor. The bidirectional telescopic driving member 474 is a bidirectional electric cylinder or a bidirectional pneumatic cylinder.

[0070] When positioning the position of the shell 23, the first telescopic drive member 473 can be used to drive the bidirectional telescopic drive member 474 downward until the positioning plate 471 contacts the mounting surface of the bolt, and then the bidirectional telescopic drive member 474 is started to drive a pair of positioning plates 471 to approach each other, thereby clamping at least two bolts on the same row, and then the angle and position of the mounting frame 41 are adjusted through the rotation adjustment of the first rotating mechanism 46 and the movement adjustment of the damping slide rail 45, so that the shell 23 corresponds to the position of the bolt.

[0071] Furthermore, a rotatable rolling wheel 472 is provided at the end of the positioning plate 471. Specifically, a support 4711 is provided at the end of the positioning plate 471, and the rolling wheel 472 is rotatably mounted on the support 4711.

[0072] The positioning plate 471 is L-shaped, including a vertical portion and a transverse portion perpendicularly connected to the vertical portion. The transverse portion can contact the mounting surface of the bolt, thereby clamping the bolt to achieve positioning.

[0073] Furthermore, a position detection device 475 is provided at the bottom of the bidirectional telescopic drive member 474. The position detection device 475 is used to detect the bolts below. After the position of the housing 23 is positioned by the positioning mechanism 47, the housing 23 is made to correspond to the bolts, and then the gluing device can be moved in the direction of the bolts, and then the bolts below are detected by the position detection device 475, and the moving distance of the device is controlled by the number of bolts detected, so that the housing 23 can be opposite to the bolts.

[0074] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, the first rotating mechanism 46 includes a rotating seat 463 connected to the top of the damping slide rail 45 and an external tooth slewing bearing 462 arranged on the rotating seat 463; the external tooth slewing bearing 462 is rotatably arranged at the bottom of a fixed frame 50; a telescopically adjustable driving gear is provided on the fixed frame 50 or the rotating seat 463 corresponding to the external tooth slewing bearing 462, and the driving gear can be engaged with or separated from the external tooth slewing bearing 462 by telescopically adjusting the driving gear.

[0078] The motor 466 can drive the driving gear to rotate, and then the driving gear drives the external gear slewing bearing 462 to rotate. The external gear slewing bearing 462 rotates and adjusts with the damping slide rail 45 and the mounting frame 41 connected below, so as to adjust the angle of the mounting frame 41. This is an active adjustment function. When it is necessary to cooperate with the positioning mechanism 47 to automatically adjust the angle, the transverse telescopic member 464 retracts, and retracts with the driving gear. The driving gear does not contact the external gear slewing bearing 462. At this time, the external gear slewing bearing 462 can be adaptively rotated and adjusted under the action of external force, that is, the first rotating mechanism is used as a passive member. After adjustment, the driving gear extends to mesh with the external gear slewing bearing 462, so that the external gear slewing bearing 462 cannot be adaptively rotated and adjusted under the action of external force.

[0079] Furthermore, a fixing plate 451 is provided at the bottom of the damping slide rail 45 , and the fixing plate 451 is fixedly connected to the top of the mounting frame 41 .

After the glue injection is completed, the shell 23 can be adjusted upward, while the conical cover 25 remains in place. The bottom of the conical cover 25 is set close to the inner side of the blade plate 24, realizing the function of scraping glue, that is, scraping the glue on the inner side of the blade plate 24, and realizing the separation of the blade plate 24 from the glue.

The relative position of the sliding plate 292 and the adjustment seat 291 can be adjusted by compressing the corresponding fine-tuning spring 294. After adjustment, the adjustment seat 291 is energized by the electromagnet to adsorb the adjustment seat 291, so that the sliding plate 292 and the adjustment seat 291 can no longer be adjusted relative to each other.
