Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a hanging basket cantilever cast-in-situ linear support device. Background Art

[0002] Basket cantilever construction uses a basket as a construction platform to cast or assemble beam segments from both sides of the bridge toward the center cantilever until the entire bridge structure is complete. The basket, the primary load-bearing structure, is anchored to the completed beam segments using anchoring devices and moves along a pre-set track to enable construction to proceed section by section.

[0003] The cantilever of the hanging basket is connected to the hanger plate through a frame, and the frame is connected to the track in a rolling manner. The installation of the hanger plate is achieved by moving the frame on the track. However, in different construction scenarios, the weight of the hanger plate is different. The frame carries hangers of different weights, and the connection forces between the frame and the back end of the hanger plate and the track are different. The connection position between the frame and the back end of the hanger plate and the track is fixed relative to the frame, and it is difficult to adjust according to the weight of the hanger plate carried by the frame. The frame and the back end of the hanger plate and the track are deformed or detached due to the force, and the frame is at risk of tilting or overturning. Therefore, it is difficult to ensure the stable movement of the frame, and thus it is difficult to ensure the linear stability of the subsequent hanging basket cantilever construction.

DETAILED DESCRIPTION

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] like Figures 1 to 5 As shown, a hanging basket cantilever cast-in-place linear support device includes a track 1 and a frame 2. There are two tracks 1, and also include a bottom beam 3, a slide 5 and an adjusting member. Each track 1 is provided with a bottom beam 3 on the upper side. The bottom beam 3 is a rectangular rod. Each bottom beam 3 is provided with a slide 5 with the left end extending out of the bottom beam 3. The left end of the slide 5 and the right end of the bottom beam 3 are connected with a connecting member 4. Each connecting member 4 is rollingly connected to the track 1 on the lower side. A limit member 9 is provided between each bottom beam 3 and the track 1 on the lower side. The upper sides of the two bottom beams 3 are connected together. It is connected to a frame 2; the adjusting member includes a connecting plate 6, a connecting rod 7 and a driving plate 8. A connecting plate 6 is connected between the left ends of the opposite surfaces of the two bottom beams 3, and a connecting rod 7 is connected between the left parts of the opposite surfaces of the two slides 5. The connecting rod 7 is located on the left side of the bottom beam 3. The left end of the driving plate 8 movably passes through the connecting plate 6 and is fixedly connected to the connecting rod 7. A through hole 17 is provided on the connecting plate 6 for the driving plate 8 to movably pass through. The connecting plate 6 is a rectangular plate, and the driving plate 8 is a rectangular plate. The driving plate 8 is driven to the left or right by a screw 10.

[0024] A sliding hole 11 is recessed on the left end surface of the bottom beam 3 . The sliding hole 11 is a rectangular hole with an open left end. A slide plate 5 is slidably arranged in the sliding hole 11 . The slide plate 5 is a rectangular plate that slides and contacts the sliding hole 11 from the side.

[0025] The track 1 is an I-shaped structure consisting of an upper side plate 1a, a web 1c and a lower side plate 1b; the connecting member 4 includes a connecting column 4a, a roller 1 4c and a roller 2 4d, the connecting column 4a is a rectangular column, the left end of the slide plate 5 and the right end of the bottom beam 3 are both connected to the connecting column on the connecting member, the bottom surface of the connecting column 4a is provided with an n-type groove 4b, the left and right ends and the lower end of the n-type groove 4b are open, the n-type groove 4b is covered outside the upper side plate 1a of the track 1, the front and rear inner surfaces of the n-type groove 4b are in sliding contact with the upper side plate 1a of the track 1, and the upper parts of the front and rear inner surfaces of the n-type groove 4b are rotatably connected with a roller 1 4c, and the roller 1 4c rolls in contact with the top surface of the upper side plate 1a of the track 1, and the lower parts of the front and rear inner surfaces of the n-type groove 4b are rotatably connected with roller 2 4d, and each roller 2 4d rolls in contact with the bottom surface of the upper side plate 1a of the track 1.

[0026] The two bottom beams 3 are provided with limit members 9 on their opposite sides, and the two limit members 9 are symmetrical in the front and rear. The front limit member 9 includes a vertical plate 9a and a cross bar 9d. The vertical plate 9a is threadedly connected to the screw rod 2 9c, and the rear end of the screw rod 2 9c is rotatably connected to the front bottom beam 3. A limit rod 9b is fixed on the front bottom beam 3, and the end thereof movably passes through the vertical plate 9a. A horizontal cross bar 9d is fixed to the lower part of the rear side surface of the vertical plate 9a, and the rear end of the cross bar 9d extends between the upper side plate 1a and the lower side plate 1b of the track 1.

[0027] The rear end of the crossbar 9d of the front limiter 9 is connected to an elastic pad 9e, which is a sheet made of elastic rubber. The upper and lower surfaces of the rear part of the crossbar 9d slide in contact with the upper plate 1a and the lower plate 1b of the track 1 respectively.

[0028] A connecting plate 2 12 is connected between the right ends of the opposite surfaces of the two bottom beams 3, and a threaded hole 13 is recessed on the right end surface of the driving plate 8. The screw 10 is threadedly connected to the threaded hole 13. The right part of the screw 10 passes through and rotates through the bearing 14 to connect the connecting plate 2 12.

[0029] The right end of the screw rod 10 is connected to a rotating plate 15 , and the opposite ends of the two screw rods 9 c are both connected to a rotating plate 2 16 .

[0030] The frame 2 includes a diamond frame 2a and a cross beam 2c. The outer top surfaces of the two bottom beams 3 are fixedly connected to the diamond frames 2a. The two diamond frames 2a are opposite to each other and parallel to each other. The two diamond frames 2a are fixedly connected via a connecting rod 2b. A cross beam 2c is connected between the upper right ends of the two diamond frames 2a, and a plurality of hanging rings 2d are provided on the bottom surface of the cross beam 2c.

[0031] The two tracks 1 of the utility model are installed and fixed on the completed bridge;

[0032] When in use, the second screw rod 9c on each limiting member 9 is rotated. When the second screw rod 9c is rotated, the connected vertical plate 9a is driven to move toward the direction of the track 1. The cross bar 9d on the limiting member 9 moves with the vertical plate 9a until the cross bar 9d is pressed against the web 1c of the track 1. The elastic pad 9e on the cross bar 9d is compressed. The elastic pad 9e can increase the friction between the cross bar 9d and the web 1c. At this time, each bottom beam 3 is limited on the track 1, and the frame 2 will not move left or right.

[0033] When a heavier hanging board is suspended on the frame 2 (the hanging board is suspended by the hanging ring 2d on the crossbeam 2c), the screw rod 10 is rotated. Since the screw rod 10 is threadedly connected to the threaded hole 13 on the driving plate 8, when the screw rod 10 is rotated, the driving plate 8 is driven to move to the left, and the driving plate 8 drives the two slide plates 5 to move to the left through the connecting rod 7. The connecting pieces 4 at the left ends of the two slide plates 5 move to the left along the track 1. Conversely, when a lighter hanging board is suspended on the frame 2, the screw rod 10 is rotated in the opposite direction, which can drive the two slide plates 5 to drive the connected connecting pieces 4 to move to the right. Therefore, the utility model can adjust the connection position of the frame 2 with the back end of the hanging board and the track 1 according to the hanging boards of different weights suspended by the frame 2, thereby ensuring the stability of the connection between the frame 2 and the track 1, avoiding the frame 2 from tilting or overturning, and ensuring the stability of the subsequent construction line.

[0034] Moreover, both bottom beams 3 are provided with limiters 9, and the crossbar 9d of each limiter 9 has a large contact area with the corresponding track 1. When the frame 2 suspends the hanging board, it can improve the connection stability between the bottom beam 3 and the lower track 1, further preventing the frame 2 from tilting or overturning, and ensuring the stability of the subsequent construction line;

[0035] When the present invention is required to move along the track 1, the screw rod 2 9c on each limit member 9 is rotated in the opposite direction to make each vertical plate 9a move in the direction away from the track 1 until the cross bar 9d on each limit member 9 drives the elastic pad 9e to disengage from the web 1c of the track 1 and stops the rotation of the screw rod 2 9c. At this time, one end of each cross bar 9d connected to the elastic pad 9e is located between the upper side plate 1a and the lower side plate 1b of the track 1, and the upper and lower surfaces of the cross bar 9d respectively slide in contact with the upper side plate 1a and the lower side plate 1b of the track 1. When the present invention is driven by the traction device and moves along the track 1, the front and rear inner surfaces of the n-shaped groove 4b of each connecting member 4 slide in contact with the track 1, and the two cross bars 9d are still relatively located in the track 1, which can prevent the bottom beam 3 from tilting left and right, thereby improving the movement stability of the present invention and avoiding the risk of tilting when the present invention moves.

[0036] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Without violating the spirit of the present invention, that is, within the scope of disclosure, any equivalent or equivalent deformation or replacement of the technical solution of the utility model shall fall within the scope of protection of the present invention.
