Detailed implementation mode

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but it shall not be used as a basis for limiting the present invention.

[0025] Embodiment of the present invention: A convenient traction and laying construction device for the catwalk surface layer, as Figures 1 - 9 shown, includes a traction frame 1. The load-bearing cable 2 and the handrail rope 3 of the catwalk pass through the traction frame 1 to achieve sliding sleeving with the traction frame 1. As Figure 4 shown, there are 8 load-bearing cables 2 and 2 handrail ropes 3. The 2 handrail ropes 3 both pass through the traction frame 1. Among the 8 load-bearing cables 2, 2 symmetrically arranged ones are selected to be slidably sleeved with the traction frame 1. A plurality of walking wheel assemblies 4 are slidably sleeved on the load-bearing cable 2 behind the traction frame 1. The load-bearing cables 2 provided with the walking wheel assemblies 4 are the 2 load-bearing cables 2 that are slidably sleeved with the traction frame 1. The cross beam 5 that is not tightened and fixed is sleeved on the load-bearing cable 2 between adjacent walking wheel assemblies 4. The cross beam 5 is generally fixed to the load-bearing cable 2 by using a riding U-bolt and a bolted plate. Before installing the cross beam 5, first connect it with the riding U-bolt and the bolted plate, and hang it on the load-bearing cable 2 through the riding U-bolt, but do not tighten the riding U-bolt first, so that the cross beam 5 can move along the load-bearing cable 2. Adjacent two walking wheel assemblies 4 are connected by a towing rope 6 with the same length. The top of the walking wheel assembly 4 supports a steel mesh surface layer 7. A plurality of lifting lug plates 8 that are not tightened and fixed are sleeved on the handrail rope 3. A suspension rod is fixedly connected to the lifting lug plate 8. Adjacent lifting lug plates 8 are also connected by a towing rope 6 with the same length. The head end of the steel mesh surface layer 7, as well as the cross beam 5 and the lifting lug plate 8 at the front end, are all connected to the tail of the traction frame 1 through the towing rope 6.

[0026] During use, the front end of the towing frame 1 is connected to a winch on one side of the shore by a steel wire rope. When the towing frame 1 moves forward along the handrail rope 3 and the load-bearing cable 2 under the drive of the winch, it will successively drive a plurality of lug plates 8, the steel mesh surface layer 7 and the walking wheel assembly 4 to move forward. When the walking wheel assembly 4 moves forward and touches the cross beam 5, it will push the cross beam 5 forward, thus realizing the rapid and convenient towing and laying of the catwalk surface layer components. Since the lengths of the towing ropes 6 between the lug plates 8 and the towing ropes 6 between the walking wheel assemblies 4 are all the same, the lug plates 8 can be evenly spaced on the handrail rope 3, the cross beams 5 can be evenly spaced on the load-bearing cable 2, and the steel mesh surface layer 7 is laid across the entire surface of the load-bearing cable 2. When the towing frame 1 moves from one side of the shore to the other side, the laying of the entire catwalk surface layer components can be completed. During the whole process, the workers only need to continuously hang the cross beams 5 on the load-bearing cable 2 and the lug plates 8 on the handrail rope 3 on one side of the shore where the cross beams 5, the steel mesh surface layer 7 and the lug plates 8 are stacked.

[0027] The towing frame 1 includes an upper towing frame and a lower towing frame. The handrail rope 3 passes through the upper towing frame, and the load-bearing cable 2 passes through the lower towing frame. The structures of the upper towing frame and the lower towing frame are similar, including two cross bars 9 arranged at intervals in the width direction of the catwalk. Guide sliding mechanisms are provided at both ends of the two cross bars 9, and the guide sliding mechanisms at both ends are symmetrically distributed. The guide sliding mechanism is arranged in the cavity between the two cross bars 9. The guide sliding mechanism includes two upper mounting plates 10 arranged at intervals and two lower mounting plates 11. The upper mounting plate 10 is vertically fixed on the inner wall of the upper cross bar 9, and the lower mounting plate 11 is vertically fixed on the inner wall of the lower cross bar 9. The upper mounting plate 10 and the lower mounting plate 11 on the same side are fixedly connected by a connecting plate A12. A pulley 13 is fixed between the two upper mounting plates 10 and the two lower mounting plates 11 respectively. The handrail rope 3 and the load-bearing cable 2 pass through between the pulleys 13.

[0028] By providing the guide sliding mechanism, it can avoid the direct contact between the cross bar 9 of the towing frame 1 and the load-bearing cable 2 and the handrail rope 3, and avoid the direct contact between the cross bar 9 and the load-bearing cable 2 or the handrail rope 3, which may cause wear of the cross bar 9, the load-bearing cable 2 and the handrail rope 3 during the moving process. The setting of the pulley 13 can realize the rapid walking of the towing frame 1.

[0029] The upper traction frame and the lower traction frame are also provided with a front-end traction frame body 14. The front-end traction frame body 14 includes left and right side frame bodies arranged symmetrically. The left and right side frame bodies are respectively composed of an upper frame body 15 and a lower frame body 16. The upper frame body 15 is arranged obliquely downward and inward, and the lower frame body 16 is arranged obliquely upward and inward. The ends of both are fixedly connected to the frame traction ear plate 17. The tails of the upper frame body 15 and the lower frame body 16 are both rotatably connected to the traction assembly 18 in the cross bar 9. The traction assembly 18 includes an upper traction plate 19 and a lower traction plate 20. The upper traction plate 19 and the lower traction plate 20 are respectively vertically fixed on the inner walls of the two cross bars 9. The outer walls of the upper traction plate 19 and the lower traction plate 20 are fixedly connected together through a connecting plate B21. The head end of the connecting plate B21 is rotatably connected to the tail of the upper frame body 15 or the lower frame body 16 through a spindle.

[0030] The frame traction ear plate 17 is used to connect the steel wire rope connected to the winch. Through the front-end traction frame body 14, the entire traction frame 1 is pulled forward along the load-bearing cable 2 and the handrail rope 3 under the action of the winch.

[0031] At the tails of the upper mounting plate 10 and the lower mounting plate 11 located outside the cross bar 9, there are both penetration holes 22, which facilitate fixing the head end of the traction rope 6 at the penetration holes 22, realizing the quick connection between the traction frame 1 and the traction rope 6.

[0032] The upper traction frame and the lower traction frame are fixedly connected together through symmetrically arranged connecting frames. The connecting frame includes connecting ear plates 23 arranged on the bottom surface of the upper traction frame and the top surface of the lower traction frame. The connecting ear plates 23 are fixedly connected together through a connecting rod 24. Through this structure, the upper traction frame and the lower traction frame are connected together to form a whole.

[0033] At the middle position of the upper traction frame, there is also a strengthening component. The strengthening component includes a strengthening main board 25 vertically fixed to the inner walls of the two cross bars 9. A strengthening sub-board 26 is fixed to the outer wall of the strengthening main board 25. Ensure the stiffness and integrity of the upper traction frame.

[0034] The traveling wheel assembly 4 includes a traveling wheel bottom plate 27. On the top surface of the traveling wheel bottom plate 27, there are two vertically spaced traveling wheel mounting plates 28. Between the two traveling wheel mounting plates 28, there is a traveling wheel 29. The traveling wheel 29 is supported on the load-bearing cable 2. A steel mesh surface layer 7 is supported on the top surface of the traveling wheel 29. A square steel 30 is fixed to the bottom of the traveling wheel bottom plate 27. Traction plates 31 are fixed to the front and rear side walls of the square steel 30. The traction rope 6 is fixedly connected to the traction plates 31. This structure can realize the rolling contact between the traveling wheel assembly 4 and the load-bearing cable 2, enabling the traveling wheel assembly 4 to move quickly under the action of traction force without damaging the load-bearing cable 2.

[0035] The utility model mainly consists of a traction frame 1, a walking wheel assembly 4 and a traction point. The winch and the traction frame 1 are respectively placed on both banks and are connected by a steel wire rope. According to the design requirements of the spacing of the cross beams 5, the catwalk deck system is connected in series at intervals with traction ropes 6 of corresponding lengths and then connected to the traction frame 1. The winch provides power to tow the deck system across the river. The walking wheel assembly 4 provides support for the deck system and prevents damage to the load-bearing cable 2 while reducing friction. Bolted connections are preferably used for the connections between the components of the traction frame 1 to facilitate installation and removal.

[0036] The traction frame 1 is composed of an upper traction frame, a lower traction frame, a front-end traction frame body 14 and a traction point. The upper traction frame and the lower traction frame are connected by bolting with steel sections. The length of the steel section should be designed according to the spacing between the upper and lower cables. The pulleys 13 inside the upper traction frame and the lower traction frame are respectively supported on the load-bearing cable 2 and the handrail rope 3 for support and movement. The upper traction frame and the lower traction frame are made of double channel steels and are bolted together through rib plates. The pulleys 13 between the beams are designed with double wheels clamping the cable from above and below to ensure that the load-bearing cable 2 and the handrail rope 3 do not come out of the groove and the cross bar 9 does not rub against the cable during the movement. The strengthening components can be added according to calculations in the length direction of the cross bar 9 to ensure the stiffness and integrity of the upper traction frame and the lower traction frame.

[0037] The front-end traction frame body 14 and the upper traction frame and the lower traction frame can be connected by a cross knot to facilitate angle adjustment. The lower frame body 16 should be higher than the lower cross beam 5, and the height difference is determined according to the span, sag and installation position of the winch (pulley) on the opposite bank. The determination principle is to minimize the average angle between the traction cable and the members during the traction process to ensure the traction efficiency.

[0038] The shackle (or pulley) is used as the connection method between the traction ear plate 17 of the frame body and the traction rope. If the winch is placed on the same bank as the surface layer material stacking, a trailing wheel is added behind the traction ear plate 17 of the frame body as the channel for the river-crossing rope.
