Description

Technical Field

[0001] The embodiments of this utility model belong to the field of bridge construction technology, and more specifically, relate to a short-distance transport trolley for spatial catwalk load-bearing cable anchors. Background Technology

[0002] With the development of infrastructure, bridges are increasingly used to cross mountainous and river valleys, and suspension bridges are often chosen for extra-large bridges. During the construction of suspension bridges, the catwalk is an indispensable part of the superstructure, and the safe construction of the load-bearing cables is particularly important. Due to the integrity requirements of the load-bearing cables in the spatial catwalk, the selection of solutions for transporting anchorages for extremely heavy load-bearing cables has become a major concern for bridge engineers.

[0003] When transporting such load-bearing cable anchors over short distances, the traditional method involves a large number of workers working with winches to directly pull the anchors across the working plane of the anchoring system. This requires workers to make directional adjustments, and adjusting heavy anchors requires the participation of many workers, which is quite dangerous. Furthermore, the ground friction during the pulling process can damage the concrete working plane of the anchoring system.

[0004] Therefore, there is an urgent need for a space catwalk-type short-distance transport trolley for load-bearing cable anchors, which can effectively solve the safety and efficiency problems in the short-distance transport of heavy anchors and reduce safety risks. Summary of the Invention

[0005] In view of the significant dangers and potential damage to concrete working surfaces during the transportation of load-bearing cable anchors in existing technologies, this utility model provides a short-distance transport trolley for load-bearing cable anchors via a spatial catwalk to solve these problems.

[0006] To achieve the above objectives, this utility model provides a short-distance transport trolley for load-bearing cable anchors in a space catwalk, comprising: a bearing plate for loading the anchor, having an arc-shaped groove at its center; positioning plates symmetrically arranged on both sides of the arc-shaped groove; an anchor head limiting assembly for limiting the anchor head, comprising a support plate fixedly disposed on the top of the positioning plate, a bolt hole opened on the support plate, and an anchor head pin passing through the bolt hole and the anchor pin hole in sequence; an anchor tail limiting assembly for limiting the anchor tail, comprising a limiting baffle disposed at the rear end of the top of the bearing plate, a limiting groove opened on the limiting baffle for the load-bearing cable to pass through, bolt rings symmetrically disposed on both sides of the limiting groove, and an anchor tail pin passing through the bolt rings to limit the top of the load-bearing cable; and a wheel assembly disposed at the bottom of the bearing plate.

[0007] Furthermore, the positioning plate is made of U-shaped steel and is symmetrically arranged on both sides of the arc-shaped groove. The bottom is fixed to the top of the bearing plate by welding, and multiple positioning holes are opened on the top.

[0008] Furthermore, the support plate has fixing ears at its front and rear ends, and bolts are threaded through the fixing ears and corresponding positioning holes to fix the support plate on the top of the positioning plate; the bolt hole is opened at the center of the support plate, and its diameter is adapted to the anchor head pin; the anchor head pin is an L-shaped rod, one end of which passes through the two sets of bolt holes and the anchor pin hole in sequence to limit the anchor head.

[0009] Furthermore, the limiting baffle is located at the rear end of the arc-shaped groove, and its bottom is fixed to the top of the bearing plate by bolts to block and limit the tail of the anchor.

[0010] Furthermore, the limiting groove is formed on the top of the limiting baffle for the passage of the load-bearing cable. The groove width is adapted to the diameter of the load-bearing cable to limit the horizontal movement of the load-bearing cable.

[0011] Furthermore, the limiting baffle is also vertically provided with a locking post, which contacts and limits the other end of the anchor tail pin to prevent it from falling off.

[0012] Furthermore, the wheel assembly is located at the bottom of the support plate and includes a load-bearing frame, a pad, rollers, a bogie, and a rotating shaft. The load-bearing frame is made of I-beams and is fixedly mounted at the bottom of the support plate. The pad is made of steel plate with through holes at its four corners, through which bolts are threadedly connected to the load-bearing frame, thus fixing the pad to the bottom of the load-bearing frame. The bogie is rotatably connected to the bottom of the pad for adjusting the trolley's direction of travel. The rotating shaft is rotatably connected to the center of the roller at its middle section, and its two ends are fixedly connected to the bogie.

[0013] Furthermore, a buffer layer made of rubber is provided inside the arc-shaped groove.

The system includes a limiting baffle 301 located at the top rear end of the support plate 1, a limiting groove 305 formed on the limiting baffle 301 for the passage of the load-bearing cable 7, bolt rings 302 symmetrically arranged on both sides of the limiting groove 305, and an anchor tail pin 304 passing through the bolt rings 302 to limit the top of the load-bearing cable 7. The wheel set 5 is located at the bottom of the support plate 1 and uses rotatable rollers for directional adjustment, allowing the transport trolley to travel on the concrete working surface and avoiding damage to the concrete working surface. This utility model provides a short-distance transport trolley for load-bearing cable anchors in a spatial catwalk. It can limit the two ends of the anchor 6, is easy to assemble and disassemble, and is highly user-friendly. The anchor is transported suspended, reducing damage to the working platform of the anchoring system during short-distance transport, and has significant promotional value.

[0035] like Figure 1-3 As shown in the embodiment of this utility model, the supporting plate 1 is used to place the loading anchor 6. It is made of steel plate and has an arc-shaped groove at the center. This arc-shaped groove is an arc-shaped recess that can accommodate anchors 6 of various diameters. Furthermore, to prevent the anchor 6 from shaking and causing damage to the supporting plate 1, a buffer layer made of rubber is provided inside the arc-shaped groove. This buffer layer can buffer and absorb the impact force of the anchor 6 shaking, reducing the damage to the supporting plate 1 caused by the shaking of the anchor 6. Preferably, the supporting plate 1 is also provided with a handrail at its end to facilitate the operator in pushing the trolley forward.

[0036] The positioning plate 2 is used to position and install the anchor head limiting component 4. It is made of U-shaped steel and is symmetrically arranged on both sides of the arc groove. The bottom is fixed to the top of the bearing plate 1 by welding. The top has multiple positioning holes. The anchor head limiting component 4 is connected and positioned by passing bolts through the corresponding positioning holes.

[0037] The anchor head limiting assembly 4 is used to limit the anchor head 602. It includes an anchor head pin 401, a bolt hole 402, and a support plate 403. The support plate 403 has fixing ears at its front and rear ends. Bolts are threaded through the fixing ears and connected to the corresponding positioning holes to fix the support plate 403 on the top of the positioning plate 2. The bolt hole 402 is located at the center of the support plate 403 and its diameter is adapted to the anchor head pin 401. The anchor head pin 401 is an L-shaped rod. One end of the rod passes through the two sets of bolt holes 402 and the anchor pin hole 603 in sequence, thereby limiting the anchor head 602 and preventing it from rotating or moving forward.

[0038] The anchor tail limiting assembly 3 is used to limit the anchor tail 601, and includes a limiting baffle 301, a bolt ring 302, an anchor tail pin 304, and a limiting groove 305. The limiting baffle 301 is located at the rear end of the arc-shaped groove, and its bottom is fixed to the top of the bearing plate 1 by bolts, thus blocking and limiting the anchor tail 601 to prevent it from moving backward. The limiting groove 305 is formed at the top of the limiting baffle 301 for the passage of the load-bearing cable 7, and its groove width is adapted to the diameter of the load-bearing cable 7, thus limiting its movement. To prevent the horizontal movement of the load-bearing cable 7, for load-bearing cables 7 of different diameters, different sizes of limiting baffles 301 can be used to make the limiting grooves 305 on the limiting baffles 301 fit the load-bearing cable 7; the bolt rings 302 are symmetrically arranged on both sides of the limiting grooves 305 and fixed to the limiting baffles 301 by welding; the anchor tail pin 304 is an L-shaped rod, one end of which passes through two sets of bolt rings 302 in sequence, thereby limiting the top of the load-bearing cable 7 and preventing it from moving vertically.

[0039] Furthermore, to prevent the load-bearing cable 7 from swaying under crosswind load during transportation, thereby causing the anchor tail pin 304 to fall off, a locking post 303 is also vertically provided on the limiting baffle 301. The locking post 303 contacts and limits the other end of the anchor tail pin 304 to prevent it from falling off.

[0040] The wheel assembly 5 is located at the bottom of the support plate 1 and includes a support frame 501, a pad 502, rollers 503, a bogie 504, and a rotating shaft 505. The support frame 501 is made of I-beams and is fixedly installed at the bottom of the support plate 1. The pad 502 is made of steel plate with through holes at its four corners. Bolts are threaded through the through holes to the support frame 501, thereby fixing the pad 502 to the bottom of the support frame 501. The bogie 504 is rotatably connected to the bottom of the pad 502 and is used to adjust the direction of travel of the trolley. The middle of the rotating shaft 505 is rotatably connected to the center of the roller 503, and both ends are fixedly connected to the bogie 504.

[0041] When the transport trolley of this utility model is used for anchor transportation, the corresponding limiting baffle 301 is selected and installed on the top of the bearing plate 1 according to the size of the anchor 6 and the load-bearing cable 7; the trolley is placed on the anchoring system working platform, and after the load-bearing cable 7 and its anchor 6 reach the designated position, the anchor 6 is guided onto the trolley by adjusting it with a winch and a hand-cranked hoist; the load-bearing cable 7 is pulled to pass through the limiting groove 305 until the anchor tail 601 contacts the limiting baffle 301; the anchor tail pin 304 is used to pass through two sets of bolt rings 302 in sequence, thereby securing the top of the load-bearing cable 7. The anchor tail pin 304 is rotated to make its other end contact the locking post 303 for limiting, thus completing the limiting operation of the anchor tail 601 and the load-bearing cable 7; the two sets of support plates 403 are connected to the corresponding positioning holes by bolts and threads, so that the bolt hole 402 is aligned with the anchor pin hole 603, and one end of the anchor head pin 401 is passed through the two sets of bolt holes 402 and the anchor pin hole 603 in sequence, thereby limiting the anchor head 602; the load-bearing cable anchor is lowered to the design position by the action of the roller 503 using a winch.

[0042] The transport trolley of this utility model is easy to assemble and disassemble, and highly operable. The anchor head limiting component and anchor tail limiting component of the transport trolley are reasonably designed. The anchor can be quickly limited or disassembled through structures such as pins. It is easy to operate and learn, which greatly improves work efficiency.

[0043] The transport trolley of this utility model adopts wheel support, which allows the anchor to be transported in the air, avoiding friction damage to the concrete working surface caused by traditional towing methods, protecting the integrity of the working platform, and reducing maintenance costs.

[0044] The transport trolley of this utility model makes full use of rotatable rollers for directional adjustment during transportation, minimizing manual intervention. It cleverly utilizes the trolley's functions to reduce the investment of construction personnel during the adjustment process, thus protecting the safety of construction personnel to a greater extent and being more economical and safer.
