They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. The terms "connected" and "connection" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0033] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0034] like Figure 1-4 As shown, a hanging basket walking auxiliary device includes a travel rail 1, a slide seat, a drive seat 2 and a positioning ratchet 11. The travel rail 1 is an I-shaped structure, which can be an I-beam or a double I-beam. The travel rail 1 is anchored on the bridge deck of the constructed bridge through a preset anchor, so as to serve as the basis for the walking of the hanging basket. A plurality of limit grooves 4 are provided on the upper surface of the travel rail 1. The limit grooves 4 are square grooves. The plurality of limit grooves 4 are evenly distributed in the length direction of the travel rail 1. In order to ensure the opening of the limit grooves 4, a pad can be laid on the travel rail 1. The pad is fixed to the upper wing plate of the travel rail 1 as a whole, thereby increasing the thickness of the upper wing plate of the travel rail 1, so as to facilitate the slotting. The slide seat is slidably assembled along the length direction of the travel rail 1, and is used to carry the hanging basket of the bridge erection machine, so that the hanging basket can walk along the travel rail 1.

[0035] The driving seat 2 is connected to the slide seat through a telescopic rod 3, and the telescopic rod 3 drives the slide seat to move by telescoping, thereby achieving the purpose of the hanging basket walking. The main body of the driving seat 2 is a plate-like structure, and slide grooves 12 are respectively provided on both sides below the driving seat 2. The length of the slide groove 12 is adapted to the length of the driving seat 2. The cross-section of the slide groove 12 is C-shaped, which is fixed under the driving seat 2 by welding and correspondingly engaged with the upper wing plate of the traveling rail 1. The two slide grooves 12 are respectively slidably assembled along both sides of the upper wing plate of the traveling rail 1 to ensure the traveling track 1 of the driving seat 2.

[0036] The driving seat 2 is fixed on the traveling rail 1 by a positioning ratchet 11. The positioning ratchet 11 is rotatably connected to the driving seat 2 and can extend into the limiting groove 4 by rotation, so that the relative position of the driving seat 2 on the traveling rail 1 is locked by the positioning ratchet 11. Taking the driving seat 2 located behind the hanging basket as an example, the hanging basket moves forward when the telescopic rod 3 is extended. When the telescopic rod 3 reaches the maximum length, the locking of the positioning ratchet 11 and the traveling rail 1 is released, the telescopic rod 3 contracts and the driving seat 2 is locked again, thereby achieving the purpose of re-driving, reducing the difficulty of anchoring the telescopic rod 3, and realizing fast and smooth driving of the hanging basket.

[0037] The telescopic rod 3 is any one of a pneumatic cylinder, a hydraulic cylinder or an electric cylinder, and is preferably a hydraulic cylinder.

[0038] In an optional embodiment, hinge plates 13 are respectively provided on both sides above the driving seat 2. There are two hinge plates 13. The driving seat 2 is fixed by welding. The telescopic rod 3 is hinged to the two hinge plates 13 near one end of the sliding seat through a first hinge shaft. The first hinge shaft passes through the end hinge hole of the telescopic rod 3 and then passes through the hinge plates 13 on both sides to form a rotational connection with the hinge plates 13. The positioning ratchet 11 is hinged to the middle of the two hinge plates 13 through a second hinge shaft. The length of the positioning ratchet 11 is adapted to the distance between the hinge position of the second hinge shaft and the bottom of the limiting groove 4. A notch 15 corresponding to the limiting groove 4 is provided in the middle of the driving seat 2. In this way, during the rotation of the positioning ratchet 11 around the second hinge shaft, the positioning ratchet 11 passes through the notch 15 and is inserted into the limiting groove 4, thereby forming a ratchet limiting structure, thereby ensuring a stable connection relationship during the driving slide.

[0039] In this embodiment, the hinged plate 13 is provided with through holes 14 on both sides corresponding to the positioning ratchet 11. After the positioning ratchet 11 extends into the limiting groove 4, pins are inserted into the through holes 14 and the through holes 14, and the two sides of the positioning ratchet 11 are limited by the pins, so that the positioning ratchet 11 can be limited in the limiting groove 4.

[0040] The limiting groove 4 is a square groove. After the pin shaft is taken out, the positioning ratchet 11 can be rotated out of the limiting groove 4, so that the driving seat can slide in any direction.

[0041] In an optional embodiment, the slide includes two boxes 6 spaced apart below the base plate 5. To ensure the structural strength of the slide, the boxes 6 are welded from steel plates, and the corresponding base plate 5 is also made of steel plates, thereby forming an n-shaped structure. The two boxes 6 can then be assembled on the travel rail 1 through limited sliding. The spacing between the two boxes 6 is adapted to the width of the travel rail 1, thereby ensuring travel stability.

[0042] In order to further reduce the friction of the travel rail 1 of the slide, at least two rollers are hingedly provided between the two boxes 6, and a rotating shaft is provided inside the roller. The rotating shaft passes through the boxes 6 on both sides and is rotatably connected thereto. A first partition 16 is provided on both sides of each roller. The first partition 16 is used to support the two boxes 6 to ensure the structural strength of the slide. The horizontal plane of the lower edge of the first partition 16 is higher than the horizontal plane of the lower edge of the roller, so that the first partition 16 will not interfere with the upper surface of the travel rail 1 in movement after the slide is in place.

[0043] There are no less than two second partitions 17 spaced apart in the box body 6, and the second partitions 17 can further strengthen the structural strength of the box body 6. The box body 6 welded by steel plates not only has high structural strength, but also is easy to manufacture, which can greatly reduce the production cost. A baffle is connected to one end of the two box bodies 6, and a hinge seat corresponding to the telescopic rod is provided on the baffle. The horizontal plane where the lower edge of the baffle is located should also be higher than the horizontal plane where the lower edge of the roller is located. The baffle can further strengthen the connection between the two box bodies 6, and serve as a connection basis for the hinge seat to connect the telescopic rod 3.

[0044] Furthermore, a limiting member 7 is detachably connected to the lower end of the box body 6. The limiting member 7 may be a thick steel plate, which is detachably fixedly connected to the lower end surface of the box body 6 by bolts.

[0045] The limiting member 7 is provided with a strip hole pointing to the box body 6 , so that the distance between the limiting member 7 and the web of the traveling rail 1 can be adjusted according to actual needs to ensure the limitation of the track of the traveling rail 1 .

[0046] Alternatively, a plurality of spaced apart screw holes are provided below the box body 6 , and a center line of the screw holes is perpendicular to the web of the traveling rail 1 , so that adaptive adjustment can be made according to actual needs and the size of the traveling rail 1 .

[0047] After being fixed by bolts, the limit member 7 extends inwardly toward the web of the traveling rail 1 so as to be located below the upper wing plate of the traveling rail 1 at the longitudinal upper limit. Therefore, when the front end of the hanging basket bears heavy objects, the limit member 7 is limited by the upper wing plate and derailment will not occur.

[0048] In this embodiment, a roller corresponding to the web of the traveling rail 1 is provided on the side of the limiting member 7, which is not shown in the figure. The roller can be embedded in the side of the limiting member 7 facing the web of the traveling rail 1, or a hinge support is provided on the limiting member 7, and the roller is connected through the hinge support. The roller is close to the web of the traveling rail 1 for guidance, thereby reducing friction and ensuring the accuracy of the limitation of the traveling rail 1.

[0049] For example, the limit member 7 is a thick steel plate, and a mounting groove extending along its length direction is provided on one side of the web of the corresponding traveling rail 1. A roller with a vertically arranged main shaft is arranged in the mounting groove. Multiple rollers are evenly distributed along the length direction of the mounting groove. The main shaft of the roller extends into both sides of the mounting groove in the longitudinal direction and is rotatably connected thereto.

[0050] In an optional embodiment, a mounting seat 9 extends out from one side of the slide, and the mounting seat 9 extends horizontally. A locking cylinder 10 is fixed to the upper surface of the mounting seat 9. A through hole is provided in the middle of the mounting seat 9. The cylinder body of the locking cylinder 10 is fixed on the mounting seat 9. The piston rod of the locking cylinder 10 passes through the mounting seat 9 and extends into an anchor hole preset in the constructed bridge deck. The anchor hole is set on the bridge deck in a preset manner, which will not be elaborated here.

[0051] During actual walking, after the telescopic rod 3 is pushed once, the piston rod of the locking cylinder 10 is facing the anchor hole, and then the piston rod of the locking cylinder 10 extends into the anchor hole to form an anchor, releasing the positioning ratchet 11 of the drive seat 2. The drive seat 2 can reach the next preset position by extending and retracting the telescopic rod 3, thereby realizing automatic driving without excessive manual participation, thereby ensuring smooth and stable operation.

[0052] In an optional embodiment, the anchor hole is a longitudinal through hole, and the piston rod of the locking cylinder 10 is threadedly connected to a support plate after passing through the anchor hole, thereby further increasing the stability of the hanging basket during construction and preventing the hanging basket from tilting or shaking.

[0053] Furthermore, there are two support plates, which respectively block the upper and lower sides of the bridge deck, thereby greatly enhancing the stability of the hanging basket.

[0054] A stopper 8 for stopping the slide is provided at the end of the travel rail 1. The stopper 8 limits and stops the extreme travel position of the slide to prevent the slide from derailing.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
