[0029] The embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art will recognize that the described embodiments can be modified in various ways or combinations thereof without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims. Furthermore, in this specification, the drawings are not drawn to scale, and the same reference numerals denote the same parts.

[0030] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. "Rotary connection" refers to a connection where the components can rotate relative to each other after connection. The directional terms mentioned in the embodiments of this application, such as "upper," "lower," "inner," and "outer," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0031] This application provides a bridge expansion joint installation tool for highway construction, including a base 1. Wheels 2 are installed around the bottom of the base 1, allowing it to move and stop at any position. A material feeding area 3 is provided on one side of the upper end of the base, and an installation part is provided on the other side of the upper end of the base, used to pick up materials from the feeding area and place them at the installation position.

[0032] The material feeding area 3 is used to place materials, such as comb-shaped expansion joint panels. The mounting part has a mounting cover 22, inside which is a rotation drive component. A lifting adjustment component is provided at the upper end of the rotation drive component. A suction component is fixedly connected to the upper end of the lifting adjustment component via an L-shaped connecting rod 13. The suction component performs suction and unloading operations on the expansion joint panels under the drive of the lifting adjustment component. The lifting adjustment component and the suction component rotate to change direction under the action of the rotation drive component.

[0033] During construction, the comb-shaped expansion joint plate to be installed can be moved to the installation location through the material release area 3. By rotating the drive component, the direction of the lifting adjustment component and the suction component is changed to the material release area 3. The lifting adjustment component drives the suction component to descend, adsorb the comb-shaped expansion joint plate and drive it to rise. Then, by rotating the drive component, the direction of the lifting adjustment component and the suction component is changed to the installation position. The lifting adjustment component drives the suction component to descend for positioning and installation. This reduces the need for manual assistance and improves overall work efficiency.

[0034] Please refer to Figure 1 , 7 The rotation drive includes a first motor 23 installed inside the mounting cover 22. The output shaft of the first motor 23 can be vertically arranged, and a connecting plate 8 is fixedly connected to the output end of the first motor 23. A limit block 25 is fixedly connected to one side of the mounting part connecting plate 8. Driven by the first motor 23, the limit block 25 can rotate accordingly.

[0035] An arc-shaped track 24 is provided on the mounting cover 22, for example, located at the outer top of the mounting cover 22. A limiting block 25 is engaged inside the arc-shaped track 24, allowing it to move in a circular motion within the arc-shaped track 24 under the drive of the first motor 23. The arc-shaped track 24 can be 180°, and its two ends are located at the mounting part and the feeding area 3, respectively, allowing the position to be switched between the mounting part and the feeding area 3.

[0036] The first motor 23 drives the connecting plate 8 to rotate. When rotating, it makes a circular motion inside the arc track 24 through the limit block 25. When it moves to the feeding position (the side where the feeding area is located), the limit block 25 abuts against one end of the arc track 24 to limit the rotation. When it moves to the unloading position (the side where the mounting part is located), the limit block 25 abuts against the other end of the arc track 24 to limit the rotation.

[0037] Please refer to Figure 1 , 2 3. The lifting and adjusting assembly includes two side rods 10 fixedly connected to the upper end of the connecting plate 8, for example, two vertically spaced side rods 10. A second motor 9 is also installed at the upper end of the connecting plate 8. A connecting strip 16 can be fixedly connected between the lower parts of the two side rods 10. The second motor 9 is located below the connecting strip 16, and the output end of the second motor 9 is mated with a lead screw 18, for example, it can be coaxially connected. The lead screw 18 passes through the connecting strip 16, and a slider 12 is threadedly connected to the outer side of the lead screw 18. The slider 12 is fixedly connected to an L-shaped connecting rod 13. A reinforcing rod 14 can be fixedly connected to one side of the L-shaped connecting rod 13, and the end of the reinforcing rod 14 is also fixedly connected to the slider 12. The slider 12 has protruding ends 19 at both ends, and a groove 20 is formed between the two protruding ends 19. The side rods 10 are inserted into the groove 20. During lifting and lowering, the second motor 9 drives the lead screw 18 to rotate, so that the slider 12 is adjusted up and down along the length of the side rods 10.

[0038] Furthermore, a top plate is connected between the top ends of the two side rods, and the lead screw 18 is rotatably connected to the top plate of the side rod 10. A set of limiting rods 11 is also fixedly connected between the connecting strip 16 and the top plate of the two side rods 10, and is set parallel to the side rods. The limiting rods 11 are set through the slider 12, and the slider 12 is slidably set with the limiting rods 11. The setting of the second motor limiting rods 11 makes the slider 12 more stable during the lifting process. At the same time, the groove 20 of the protrusion 19 is engaged with the two sides of the side rod 10 to ensure stability during the lifting process and ensure accurate positioning.

[0039] The suction device includes a suction plate 15 fixedly connected to the end of the L-shaped connecting rod 13, and a number of strip electromagnets 17 are provided on the suction plate 15. A connecting rod 5 is fixedly connected to the lower end of the base 1, and a handle 6 is fixedly connected to the upper end of the connecting rod 5. A control button 7 is installed in the middle of the handle 6. A storage battery 21 is provided on both sides inside the mounting cover. The control button 7 is electrically connected to the storage battery 21, the first motor 23 and the second motor 9.

[0040] The battery 21 is used for power supply. The first motor 23 and the second motor 9 are controlled by the control button 7. The connecting rod 5 and the handle 6 are used for manual pushing. When powered, the bar electromagnet 17 has strong magnetism and can attract the comb-shaped expansion joint plate.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
