Technical Field

[0001] The present application relates to the technical field of bridge demolition, and in particular to an inclined lifting device for tower demolition. Background Art

[0002] A cable-stayed bridge, also known as a cable-stayed bridge, is a bridge in which the main beam is directly pulled on the bridge tower by many cables. It belongs to the cable system bridge. It is a structural system composed of a pressure-bearing tower, a tensioned cable and a bending beam. It can be regarded as a multi-span elastically supported continuous beam with cables replacing piers. A cable-stayed bridge can reduce the bending moment in the beam body, reduce the building height, reduce the weight of the structure, and save materials. When the cable-stayed bridge needs to be dismantled due to factors such as the environment and the service life, the main tower of the cable-stayed bridge needs to be dismantled. When dismantling the main tower of the cable-stayed bridge, it is necessary to use a hoist to lift the cut part of the tower structure away. The existing solution is to knock down the concrete part of the tower structure to expose the steel bars, and then use a steel wire rope to pass through the steel bars to fix it, and then lift it away. However, this operation is very cumbersome and unsafe.

[0003] In the process of implementing this application, the inventor found that there are at least the following problems in this technology: Utility Model Content

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0032] The embodiment of the present application discloses an inclined lifting device for tower dismantling.

[0033] refer to Figure 1 The tilting lifting device for tower dismantling includes two first abutment plates 200 and two second abutment plates 300.

The two second abutment plates 300 are respectively slidably connected to the two grooves 110 of the tower column 100 to which the first abutment plates 200 are slidably connected. An adjusting mechanism 400 for adjusting the sliding of the first abutment plates 200 and the second abutment plates 300 is commonly provided between the first abutment plates 200 and the second abutment plates 300. Steel wire ropes 600 are also passed through the two first abutment plates 200 and the two second abutment plates 300, and a lifting ring 700 is fixedly connected to the steel wire ropes 600. A limiting mechanism 500 for limiting the steel wire ropes 600 is also provided on the two first abutment plates 200 and the two second abutment plates 300.

[0034] When the tower column 100 is being dismantled, the adjustment mechanism 400 drives the first abutment plate 200 and the second abutment plate 300 to press against the two side walls of the groove 110 of the tower column 100, and then the wire rope 600 is passed through the two first abutment plates 200 and the two second abutment plates 300. At this time, the limiting mechanism 500 limits the wire rope 600, reducing the probability of the wire rope 600 sliding. Then the crane lifts the lifting ring 700, and the lifting ring 700 drives the cut tower column 100 to be lifted and transferred through the wire rope 600, thereby facilitating the dismantling of the cable-stayed bridge tower column 100, simplifying the operation process, and improving the operation safety.

[0035] refer to Figure 2 The adjustment mechanism 400 includes two first lead screws 410, which are rotatably connected to the end surfaces of the two first abutment plates 200 close to the second abutment plates 300, and the end surfaces of the two second abutment plates 300 close to the first abutment plates 200 are rotatably connected with second lead screws 420. The threads of the first lead screw 410 and the second lead screw 420 are opened in opposite directions. The two first lead screws 410 are threadedly connected with screw sleeves 430, and the two screw sleeves 430 are threadedly connected to the two second lead screws 420, respectively; the end surfaces of the first abutment plate 200 and the second abutment plate 300 located in the same groove 110 that are away from each other are both provided with anti-slip grooves 210.

[0036] When the first abutment plate 200 and the second abutment plate 300 are pressed against the side wall of the groove 110, the screw sleeve 430 is manually rotated, and the screw sleeve 430 drives the first screw 410 and the second screw 420 to rotate, and the first screw 410 and the second screw 420 respectively drive the first abutment plate 200 and the second abutment plate 300 to move away from each other and press against the side wall of the groove 110; the provision of the anti-slip pattern 210 increases the friction between the first abutment plate 200 and the second abutment plate 300 and the tower column 100, thereby reducing the probability of the first abutment plate 200 and the second abutment plate 300 slipping, thereby improving operational safety.

[0037] refer to Figure 3 A first rotating groove 310 is provided on the end surfaces of the first abutment plate 200 and the second abutment plate 300 located in the same groove 110 that are close to each other, a second rotating groove 320 is provided on the bottom wall of the first rotating groove 310, and a limiting groove 330 is provided on the side wall of the first rotating groove 310. The adjusting mechanism 400 also includes a rotating assembly 440, and the rotating assembly 440 includes four bearings 441, and the four bearings 441 are respectively rotatably connected to the four first rotating grooves 310, and the two first lead screws 410 and the two second lead screws 420 are respectively inserted into the four bearings 441, and the side walls of the two first lead screws 410 and the two second lead screws 420 are also fixedly connected to the limiting blocks 442, and the limiting blocks 442 are rotatably connected in the second rotating grooves 320.

[0038] The provision of the bearing 441 facilitates the rotation of the first lead screw 410 and the second lead screw 420 , while the provision of the limit block 442 reduces the probability of the first lead screw 410 separating from the first abutment plate 200 and the second lead screw 420 separating from the second abutment plate 300 .

[0039] The adjusting mechanism 400 also includes a blocking assembly 450, which includes four sealing rings 451, which are rotatably connected to the two first lead screws 410 and the two second lead screws 420 respectively, and the end faces of the two sealing rings 451 located in the same groove 110 that are away from each other are fixedly connected with sealing gaskets 452. The blocking assembly 450 also includes a plurality of fixing bolts 453, and the plurality of fixing bolts 453 are evenly divided into four groups. The four groups of fixing bolts 453 respectively pass through the four sealing rings 451 in turn and are threadedly connected to the two first abutment plates 200 and the two second abutment plates 300; the provision of the sealing rings 451 and the sealing gaskets 452 reduces the probability of debris in the working environment entering the bearing 441 and causing damage to the bearing 441.

[0040] refer to Figure 4 The limiting mechanism 500 includes four second limiting blocks 510, which are respectively fixedly connected to the two first abutment plates 200 and the two second abutment plates 300. The end surfaces of the four second limiting blocks 510 close to the ground are each provided with an arc groove 511, and the bottom walls of the four arc grooves 511 are each fixedly connected to a rubber pad 520.

[0041] When the wire rope 600 is being threaded, the second limit block 510 is set to limit the wire rope 600 and place the wire rope 600 in the arc groove 511, thereby reducing the probability of displacement of the wire rope 600. The setting of the rubber pad 520 reduces the probability of direct contact between the wire rope 600 and the second limit block 510, thereby reducing the wear of the wire rope 600 on the second limit block 510.

[0042] The implementation principle of the inclined lifting device for tower dismantling in the embodiment of the present application is as follows: when dismantling the tower column 100, first manually rotate the screw sleeve 430, the screw sleeve 430 drives the first screw 410 and the second screw 420 to rotate, the first screw 410 and the second screw 420 respectively drive the first abutment plate 200 and the second abutment plate 300 to press against the two side walls of the groove 110, and then pass the wire rope 600 through the arc groove 511, and then the crane lifts the lifting ring 700, and the lifting ring 700 drives the cut tower column 100 to be transferred through the wire rope 600.
