It is achieved by setting a hydraulic self-elevating integrated cable-stayed bridge lifting formwork attached to the surface side wall of the structure. After the construction of a single section of the structure is completed, it is lifted to the hoisting position of the next section through the lifting system of the formwork, and the cycle is repeated in sequence. The process operation is simple, construction time is saved, and construction efficiency is improved.

[0004] However, when the overhead crane is pushed by an oil cylinder, after the oil cylinder is pushed a certain distance, the part of the oil cylinder fixed to the crossbeam needs to be disassembled, the push rod of the oil cylinder returns to its original position, and then the end seat of the oil cylinder is fixed on the crossbeam, and then it is pushed by the oil cylinder push rod to move. The disassembly is troublesome, the efficiency is low, and the effect is poor. Utility model content:

[0025] In the embodiment, as shown in Figures 1 to 7 , a moving mechanism of a transverse trolley of a self-climbing tower crane includes a main truss assembly 10 and a transverse trolley 20. The main truss assembly 10 and the transverse trolley 20 are basically the same as the existing equipment and will not be described in detail here. A horizontal moving frame 30 is placed on the front and rear transverse beams 11 of the main truss assembly 10, and a transverse trolley 20 is installed on the horizontal moving frame 30;

[0026] Connecting seats 31 are fixed on the front and rear right side walls of the lower beam on the right side of the horizontal moving frame 30. The left end of the push rod of the moving oil cylinder 32 is movably connected to the connecting seat 31 through a hinge shaft. The right connecting seat 33 of the moving oil cylinder 32 is movably connected to a movable fixed seat 40 through a hinge shaft. The bottom surface of the bottom plate of the movable fixed seat 40 is pressed against the top surface of the corresponding transverse beam 11 of the main truss assembly 10;

[0027] The movable fixed seat 40 includes a bottom plate and side fixing plates 41 fixed on the front and rear top surfaces of the bottom plate. A flipping positioning plate 42 is located between the two side fixing plates 41. A central rotating shaft 43 is inserted into the middle through hole of the flipping positioning plate 42. The front and rear ends of the central rotating shaft 43 are fixed on the two side fixing plates 41. The bottom of the flipping positioning plate 42 is inserted into a corresponding slot 111 formed on the top surface of the corresponding transverse beam 11;

[0028] At the left and right sides of the upper part of the flipping positioning plate 42, there are provided limit pins 44. The front and rear parts of the limit pins 44 are inserted into corresponding jacks 411 on the two side fixing plates 41. The left and right side walls of the upper part of the flipping positioning plate 42 are close to or in contact with the side walls of the corresponding limit pins 44.

[0029] Furthermore, in the middle of the inner side walls of the two side fixing plates 41, an intermediate reinforcing plate 45 is fixed. The front and rear parts of the central rotating shaft 43 are clamped on the inner side walls of the central through holes of the corresponding intermediate reinforcing plate 45 and the inner side walls of the central through holes of the side fixing plates 41. The intermediate reinforcing plate 45 can improve the firmness of the side fixing plates 41 and enhance the strength of the moving fixing seat 40.

[0030] Furthermore, the front and rear parts of the limit pins 44 are inserted into corresponding through holes on the corresponding intermediate reinforcing plate 45 and are fixed. For example, radial extension positioning through holes are formed at both ends of the limit pins 44 extending out of the two side fixing plates 41, and positioning pins are clamped in the corresponding positioning through holes. The two ends of the positioning pins extend out of the two ends of the positioning through holes, so that the limit pin shafts 44 will not move out of the corresponding jacks 411 and the corresponding through holes on the intermediate reinforcing plate 45.

[0031] Furthermore, the left and right side walls in the middle of the flipping positioning plate 42 are arc-shaped wall surfaces protruding outwards. The distance between the middles of the two arc-shaped wall surfaces is greater than the distance between the left and right side walls of the upper part of the flipping positioning plate 42.

[0032] Furthermore, the lower part of the flipping positioning plate 42 is inserted into a central through groove 46 formed in the middle of the bottom plate of the moving fixing seat 40.

[0033] Furthermore, a plurality of upper connection through holes are formed in the front and rear portions of the bottom plate of the movable fixing base 40. Two pressing plates 48 are located below the front and rear portions of the bottom plate of the movable fixing base 40 and below the front and rear portions of the top plate of the transverse beam 11. A plurality of lower through holes are formed in the pressing plates 48. The screw portion of the fixing bolt 1 is inserted into the corresponding lower through holes and upper connection through holes. The top end of the screw portion of the fixing bolt 1 extends out of the top surface of the bottom plate of the movable fixing base 40 and is sleeved with a washer 2 and screwed with a locking nut 3. The washer 2 is clamped between the bottom surface of the locking nut 3 and the top surface of the bottom plate of the movable fixing base 40. An elastic pressing sleeve 4 is sleeved on the screw portion of the fixing bolt 1. The top surface of the elastic pressing sleeve 4 abuts against the top surface of the bottom plate of the movable fixing base 40, and the bottom surface abuts against the top surface of the corresponding pressing plate 48. The front and rear portions of the top plate of the transverse beam 11 are clamped between the top surface of the corresponding pressing plate 48 and the bottom surface of the bottom plate of the movable fixing base 40. When this structure is in use, by tightening the locking nut 3, and by clamping the front and rear portions of the top plate of the transverse beam 11 between the top surface of the corresponding pressing plate 48 and the bottom surface of the bottom plate of the movable fixing base 40, the movable fixing base 40 can be fixed on the transverse beam 11 to achieve fixation.

[0034] Furthermore, the horizontal moving frame 30 includes two lower beams extending forward and backward on the left and right. Fixed connection beams are provided in the front and rear portions between the two lower beams, and the two ends of the fixed connection beams are fixed to the inner side walls of the two lower beams.

[0035] A polytetrafluoroethylene plate 5 is fixed to the bottom surface of the lower beam. The bottom surface of the polytetrafluoroethylene plate 5 abuts against the top surface of the top plate of the corresponding transverse beam 11. The polytetrafluoroethylene plate 5 can ensure that when the horizontal moving frame 30 moves along the two transverse beams 11, the lubrication effect is reduced and the moving effect is improved.

[0036] Furthermore, a plurality of guiding connection seats 34 are fixed to the bottom surfaces of the front end and the rear end of the lower beam. A limiting block 35 is fixed to the lower portion of the guiding connection seat 34 at the foremost end and the rearmost end of the lower beam facing one side of the transverse beam 11. The side portions of the top plates of the two transverse beams 11 away from each other are located between the corresponding limiting blocks 35 and the bottom surface of the lower beam.

[0037] An inner side connection seat 36 is fixed to the bottom surface of the lower beam at the side where the two transverse beams 11 are close to each other. A transverse abutting wheel 37 is movably connected to the inner side connection seat 36. The outer side wall of the transverse abutting wheel 37 is close to the side wall of the inner side of the top plate of the corresponding transverse beam 11.

[0038] The arrangement of the limiting blocks 35, the guiding connection seats 34 and the transverse abutting wheels 37 can ensure that when the horizontal moving frame 30 moves along the two transverse beams 11, the position is not easily deviated, ensuring normal movement.

[0039] The principle during movement in this embodiment is as follows: When it is necessary to move the horizontal moving frame 30 to the right, pull out the limit pin 44 on the left side. Then, loosen all the locking nuts 3. By the push of the push rod of the moving oil cylinder 32, the main body of the moving oil cylinder 32 moves. At this time, due to the block of the limit pin 44 on the right side, the flipping positioning plate 42 rotates clockwise and flips out from the corresponding slot 111. Then, move one position to the right. Then, the flipping positioning plate 42 returns to its position, and its bottom is inserted into the corresponding slot 111 at this time. Then, the push rod of the moving oil cylinder 32 retracts. At this time, due to the block of the limit pin 44 on the right side, the flipping positioning plate 42 cannot rotate counterclockwise, so that the main body of the moving oil cylinder 32 does not move. As the push rod retracts, the horizontal moving frame 30 and the transverse moving cart 20 on it move one position to the right. In this way, the horizontal moving frame 30 and the transverse moving cart 20 on it can be continuously moved to the right until they reach the required position. At this time, the bottom of the flipping positioning plate 42 is inserted into the corresponding slot 111, and all the locking nuts 3 are tightened, thus completing the fixation and achieving the movement.

[0040] When this embodiment is in use, the two moving oil cylinders 32 on the top surfaces of the two transverse beams 11 operate synchronously to achieve the movement. The middle part of the top plate of the transverse beam 11 is formed with a plurality of jacks 111, and the distance between every two adjacent slots 111 is the same, so as to ensure that each time the push rod of the moving oil cylinder 32 is pushed, the bottom of the flipping positioning plate 42 can be inserted into the corresponding slot 111 to complete the movement in place.

[0041] When it is necessary to move the horizontal moving frame 30 to the left, it is necessary to pull out the limit pin 44 on the right side and retain the limit pin 44 on the left side. Just operate the moving oil cylinder 32, which is very convenient.

[0042] Finally, it should be pointed out that the above embodiments are only relatively representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and there can be many variations. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention should be considered to fall within the protection scope of the present invention.
