Therefore, they should not be construed as limitations on this utility model.

[0019] Example 1 This embodiment provides a single-box girder quay bridge based on a main trolley wire rope winding system, such as... Figures 1-4 As shown, it includes a single box girder, which is composed of a first part 1 and a second part 2. The first part 1 and the second part 2 are hinged together. Tracks are provided on both sides of the single box girder. Since the single box girder is composed of the first part 1 and the second part 2, the track is also composed of two hinged parts. The track cooperates with the traveling wheels of the traveling vehicle 3. The vehicle body of the traveling vehicle 3 is set below the single box girder. The traveling vehicle 3 is connected to the track by suspension. The traveling vehicle 3 can travel along the track by traveling wheels, thereby realizing travel along the length direction of the single box girder.

[0020] The structure of the single box girder and the traveling vehicle 3 can be achieved using existing technologies, and further technical details will not be described in detail here.

[0021] In this embodiment, the power equipment connected to the wheels on the traditional walking vehicle 3 is omitted. A first set of balance pulleys is set on the land side upper surface of the walking vehicle body, and a second set of balance pulleys is set on the sea side upper surface. The rest of the walking vehicle structure can use existing technology and will not be described in detail here.

[0022] A drive drum 4 is installed above the set position of the single box girder. The drive drum 4 is connected to a rotating drive component installed on the upper surface of the single box girder. The rotating drive component can be a motor or a reducer, which can drive the drive drum to rotate around its own axis.

[0023] One end of the drive drum 4 is connected to the output shaft of the reducer, the reducer is connected to the output shaft of the motor, and the other end of the drive drum is rotatably connected to the drive drum bracket.

[0024] In this embodiment, the drive drum 4, the drive drum bracket and the rotation drive component are all located inside the machine room, which is fixed to the upper surface of the single box girder.

[0025] The tail end of the single box girder is equipped with a tail pulley assembly, and a land-side steel wire rope is wound between the drive drum, the tail pulley assembly, and the first balance pulley assembly.

[0026] The head of the single box girder is equipped with a head pulley assembly, and a sea-side steel wire rope is wound between the drive drum, the head pulley assembly, and the second balance pulley assembly.

[0027] The tail pulley assembly includes a first pulley 5, a second pulley 6, a third pulley 7, and a fourth pulley 8.

[0028] like Figures 5-6 As shown, the first pulley 5 and the second pulley 6 are respectively located at the two ends of the upper edge of the tail of the single box girder, and the third pulley 7 and the fourth pulley 8 are respectively located at the two ends of the lower edge of the tail of the single box girder. The four pulleys are rotatably connected to the pulley bracket, and the pulley bracket is fixedly connected to the tail of the single box girder. The tops of the first pulley 5 and the second pulley 6 are located above the plane of the upper surface of the single box girder, which is adapted to the position of the drive drum 4. The bottoms of the third pulley 7 and the fourth pulley 8 are located below the plane of the lower surface of the single box girder, which is adapted to the position of the first balance pulley group.

[0029] In this embodiment, since the cross-section of the single box girder is an isosceles trapezoid, the distance between the first pulley 5 and the second pulley 6 is smaller than the distance between the third pulley 7 and the fourth pulley 8. The first pulley 5, the second pulley 6, the third pulley 7, and the fourth pulley 8 are arranged in a figure-eight shape. This arrangement ensures that the connection position between the land-side wire rope 9 and the drive drum 4 is located inside the connection position between the sea-side wire rope 10 and the drive drum 4. This ensures that the angle between the upper part of the land-side wire rope 9 above the single box girder and the drive drum 4 is within a reasonable range, preventing the drive drum 4 from becoming too long and avoiding interference between the land-side wire rope 9 and the sea-side wire rope 10.

[0030] like Figure 8 As shown, the first balancing pulley group includes a fifth pulley 11 and a sixth pulley 12, wherein the fifth pulley 11 is located on the same side as the first pulley 5 and the third pulley 7, and the sixth pulley 12 is located on the same side as the second pulley 6 and the fourth pulley 8.

[0031] One end of the landside wire rope 9 is connected to the drive drum 4. The landside wire rope 9 passes through the first pulley 5, the third pulley 7, the fifth pulley 11, the sixth pulley 12, the fourth pulley 8, and the second pulley 6 in sequence, and its other end is connected to the drive drum 4 to form a closed loop path.

[0032] In this embodiment, one end of the landside wire rope 9 is wound in the first helical groove of the drive drum 4, and the other end is wound in the second helical groove of the drive drum 4. The first and second helical grooves have opposite directions of rotation.

[0033] like Figure 7 As shown, the head pulley group includes a seventh pulley 13, an eighth pulley 14, a ninth pulley 15, and a tenth pulley 16. The ninth pulley 15 and the tenth pulley 16 are located at the two ends of the lower edge of the head of the single box girder, respectively. The seventh pulley 13 is located directly above the ninth pulley 15, and the eighth pulley 14 is located directly above the tenth pulley 16. All four pulleys are rotatably connected to the pulley bracket, and the pulley bracket is fixed to the head of the single box girder.

[0034] The second balancing pulley group includes an eleventh pulley 17 and a twelfth pulley 18, wherein the eleventh pulley 17 is located on the same side as the seventh pulley 13 and the ninth pulley 15, and the twelfth pulley 18 is located on the same side as the eighth pulley 14 and the tenth pulley 16.

[0035] The positions of the seventh pulley 13 and the eighth pulley 14 are adapted to the position of the drive drum 4, and the positions of the ninth pulley 15 and the tenth pulley 16 are adapted to the position of the second balance pulley group.

[0036] One end of the seaside wire rope 10 is connected to the drive drum 4. The seaside wire rope 10 passes through the seventh pulley 13, the ninth pulley 15, the eleventh pulley 17, the twelfth pulley 18, the tenth pulley 16 and the eighth pulley 14 in sequence, and its other end is connected to the drive drum 4 to form a closed loop path.

[0037] In this embodiment, one end of the seaside wire rope 10 is wound in the first spiral groove of the drive drum 4, and the other end is wound in the second spiral groove of the drive drum 4.

[0038] In this embodiment, the distance between the drive drum 4 and the tail end of the single box girder is less than the distance between the drive drum and the head end of the single box girder. In this embodiment, the sea-side wire rope is connected to a tensioning mechanism 19. The function of the tensioning mechanism on the sea-side rope is: on the one hand, to control the deflection angle of the sea-side wire rope to ensure that the sea-side wire rope runs on both sides of the single box girder; on the other hand, to control the sea-side wire rope to pass smoothly through the portal frame structure at the hinge point.

[0039] In this embodiment, tensioning mechanisms 19 are connected to the sea-side steel wire rope 10 between the seventh pulley 13, the drive drum 4, and the eighth pulley 14, the drive drum 4. The tensioning mechanisms 19 are located near the hinged positions of the two parts of the single box girder. The two tensioning mechanisms 19 have the same structure. Taking one of the tensioning mechanisms as an example, the following description is provided: like Figures 9-10 As shown, the tensioning structure 19 includes a bracket 19-1, which is fixedly connected to the single box beam. A reversing wheel 19-2 is rotatably connected to the bottom of the bracket 19-1 via a reversing wheel bracket. A tensioning wheel 19-3 is provided above the reversing wheel 19-2. The tensioning wheel 19-3 is rotatably connected to a wheel frame. The wheel frame is connected to a lifting drive component installed on the bracket. In this embodiment, the lifting drive component is a cylinder or hydraulic cylinder 19-4 with its axis set vertically. Preferably, a hydraulic cylinder 19-4 is used. The cylinder body of the hydraulic cylinder 19-4 is fixedly connected to the bracket, and its piston rod is connected to the tensioning wheel 19-3 via the wheel frame.

[0040] The way the seaside steel wire rope 10 is wound on the tensioning mechanism is as follows: The seaside wire rope 10, which extends from the drive drum 4, passes around the reversing pulley 19-2 on the seaside side, then passes over the tensioning pulley 19-3 from the top side, and then passes around the reversing pulley 19-2 again before extending in a direction away from the drive drum 4.

[0041] The hydraulic cylinder 19-4 drives the tensioning wheel 19-3 to rise, which can tension the steel wire rope 10 on the sea side.

[0042] Furthermore, a roller assembly 20 is provided at the hinge position of the first and second parts of the single box girder. When the two parts of the unidirectional beam rotate relative to each other, the roller assembly 20 contacts the sea-side steel wire ropes below and above the single box girder when the single box girder is tilted up, assisting the sea-side steel wire ropes to bend as the single box girder tilts up, thus avoiding wear on the steel wire ropes.

[0043] In this embodiment, as Figure 11 As shown, the idler assembly includes a first idler 20-1 and a second idler 20-2. The first idler 20-1 is rotatably connected to a first idler bracket, which is fixed to the bottom surface of the first part 1. The second idler 20-2 is rotatably connected to a second idler bracket, which is fixed to the bottom surface of the second part 2. The assembly also includes a third idler 20-3 located above the hinge position. The third idler 20-3 is rotatably connected to a third idler bracket, which is fixed to the side of the bracket 19-1 of the tensioning mechanism 19.

[0044] Furthermore, such as Figure 12 As shown, an anti-wear roller 21 is provided below the set position of the two sea-side steel wire ropes 10 located above the single box girder. The anti-wear roller 21 is rotatably connected to the anti-wear roller bracket, and the anti-wear roller bracket is fixed on the upper surface of the single box girder.

[0045] The position of the anti-wear roller 21 can be set according to actual needs, and will not be described in detail here.

[0046] Furthermore, such as Figure 13 As shown, wear-resistant blocks 22 are installed below the designated positions of the two landside wire ropes located above the single box girder. The wear-resistant blocks 22 are fixedly connected to the wear-resistant block bracket, which is fixed to the upper surface of the single box girder. The placement of the wear-resistant blocks 22 can be set according to actual needs and will not be described in detail here.

[0047] The anti-wear roller 21 and the anti-wear block 22 can contact the sea-side wire rope and the land-side wire rope, thus preventing wear and damage to the sea-side wire rope and the land-side wire rope.

[0048] The remaining structures of the single-box girder quay bridge in this embodiment can be constructed using existing technologies, and will not be described in detail here.

[0049] In this embodiment of the single-box girder quay crane, when the rotating drive unit drives the drive drum to rotate, it can drive the traveling trolley to move along the track through the sea-side steel wire rope and the land-side steel wire rope. Only the first and second balance pulley groups need to be installed on the traveling trolley, eliminating the need for power equipment connected to the traveling wheels. This greatly reduces the weight and structural complexity of the traveling trolley and lowers the maintenance difficulty. At the same time, the movement of the traveling trolley by pulling the sea-side and land-side steel wire ropes avoids the phenomenon of the traveling trolley slipping on the track, which is beneficial to the operation of the operators and safe production.

[0050] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
