Description

Technical Field

[0001] This utility model relates to the field of cable tower construction technology in bridge engineering, and in particular to an adjustable angle steel anchor box storage device. Background Technology

[0002] With the advancement of transportation infrastructure construction, the design requirements and construction complexity of bridge tower structures are increasing simultaneously. To meet the demands for span capacity, load-bearing performance, and aesthetics, cable towers are gradually evolving towards variable cross-sections and irregular curves. As a core load-bearing component, the installation accuracy of steel anchor boxes directly affects project quality and safety. Furthermore, their tilt angle and the height difference between their two sides continuously change with the construction height of the cable tower. How to achieve efficient and precise pre-installation preparation of steel anchor boxes under complex conditions has become a critical issue that urgently needs to be addressed in the field of cable tower construction.

[0003] Currently, in the field of cable tower construction, the industry generally uses steel anchor box storage brackets for the storage and hoisting of steel anchor boxes. These brackets can stably support the steel anchor boxes and ensure that the bottom plate of the steel anchor boxes is placed horizontally, so that the steel anchor boxes remain stable during the waiting stage for hoisting construction. When the hoisting operation is officially carried out, the tilt angle of the steel anchor boxes is adjusted according to the construction requirements to complete the connection between the steel anchor boxes and the cable tower structure.

[0004] However, with the increasing prevalence of cable towers with variable cross-sections and irregular curved appearances, the tilt angle and height difference between the two sides of the steel anchor box vary more complexly as the construction height changes. Conventional techniques can only adjust the angle during hoisting operations, which means that the steel anchor box cannot be pre-matched to the actual construction angle of the cable tower before installation. This requires repeated adjustments to the position during subsequent hoisting, greatly increasing the difficulty of positioning the steel anchor box and extending the construction period.

[0005] Therefore, there is an urgent need to provide an adjustable angle steel anchor box storage device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an adjustable angle steel anchor box storage device that can stably adjust the tilt angle of the steel anchor box.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] An adjustable-angle steel anchor box storage device includes:

[0009] Two support members are spaced apart along a first direction, and each support member extends along a second direction, the second direction being perpendicular to the first direction;

[0010] Four adjustment mechanisms are symmetrically arranged on the two support members, and the two adjustment mechanisms on each support member are spaced apart along the second direction. Each adjustment mechanism includes a base plate and at least two sets of drive components. The drive components are located at both ends of the base plate along the second direction and are vertically connected to the support member. The steel anchor box is erected on the four base plates. Each set of drive components can independently drive the base plate to move in the vertical direction to adjust the tilt angle of the steel anchor box.

[0011] At least two support mechanisms are respectively disposed on two support members. Each support mechanism includes two slide rails and two telescopic components. The two slide rails are disposed on both sides of the steel anchor box along the second direction and connected to the support member. The two telescopic components are disposed on both sides of the steel anchor box along the second direction. One end of the telescopic component is adjustablely connected to the slide rail along the second direction, and the other end is rotatably connected to the steel anchor box.

[0012] Preferably, the drive assembly includes a lead screw and two adjusting nuts. The lead screw is vertically connected to the support member, and the base plate is movably sleeved on the lead screw along the vertical direction. The two adjusting nuts are respectively disposed on both sides of the base plate along the vertical direction and screwed to the lead screw.

[0013] Preferably, the drive assembly further includes a pad plate, which is welded to the support member and has a support groove, and the lead screw is inserted into the support groove and welded to the pad plate.

[0014] Preferably, the telescopic assembly includes two threaded adjusting rods and a threaded sleeve. The two ends of the threaded sleeve are fitted and screwed onto the two threaded adjusting rods in a corresponding manner. One of the threaded adjusting rods is adjustablely connected to the slide rail along the second direction, and the other threaded adjusting rod is rotatably connected to the steel anchor box.

[0015] Preferably, each of the support mechanisms further includes two first connectors, which are connected one-to-one to the ends of the two telescopic components away from the steel anchor box. The first connectors are slidably disposed in the groove of the slide rail along the second direction. The first connectors are provided with first connecting holes. The slide rail is provided with a plurality of limiting holes at uniform intervals along the second direction. The first connecting hole can be selectively aligned with one of the limiting holes and fixed by a pin.

[0016] Preferably, each of the support mechanisms further includes two second connectors and two third connectors. The two second connectors are connected one-to-one to the ends of the two telescopic components away from the slide rail and have second connection holes. The two third connectors are connected to both sides of the steel anchor box along the second direction and have third connection holes. The second connection holes and the third connection holes are aligned and have pins inserted through them.

[0017] Preferably, the second connector includes two spaced-apart ear plates, each ear plate having a through hole. The two through holes are coaxially aligned to form the second connecting hole. The third connector extends between the two ear plates, and the third connecting hole is coaxially aligned with the two through holes and through which the pin passes.

[0018] Preferably, the support member comprises at least three steel profiles connected sequentially along a first direction.

[0019] The beneficial effects of this utility model are:

[0020] This invention provides an adjustable-angle steel anchor box storage device. Each set of drive components can independently drive the base plate to move vertically. By controlling the lifting height of the drive components in different adjustment mechanisms, the tilt angle of the steel anchor box can be flexibly adjusted, allowing it to match the actual angle required by the changing height of the cable tower during the storage stage. This avoids repeated adjustments during hoisting, reduces positioning difficulty, and shortens the construction cycle. Simultaneously, to ensure the stability of the steel anchor box after angle pre-adjustment, one end of the telescopic component can be adjusted to a second-direction position along the slide rail, while the other end is rotatably connected to the steel anchor box. This provides stable support after the angle is pre-adjusted, preventing displacement or tipping, and maintains effective connection with the steel anchor box through position sliding and its own telescopic movement during angle adjustment. This adapts to the support requirements under different tilt angles, further ensuring the reliability of the preparation before steel anchor box installation. Attached Figure Description

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1-6 As shown, this utility model provides an adjustable angle steel anchor box storage device, including a support member 1, an adjustment mechanism 2, and a support mechanism 3. Two support members 1 are spaced apart along a first direction, and each support member 1 extends along a second direction, which is perpendicular to the first direction. Four adjustment mechanisms 2 are symmetrically arranged on two support members 1, and two adjustment mechanisms 2 on each support member 1 are spaced apart along the second direction. Each adjustment mechanism 2 includes a base plate 21 and at least two sets of drive components 22. The drive components 22 are located at both ends of the base plate 21 along the second direction and are perpendicularly connected to the support member 1. The steel anchor box 100 is erected on four base plates 21. Each set of drive components 22 can independently drive the base plate 21 to move vertically to adjust the tilt angle of the steel anchor box 100. At least two support mechanisms 3 are respectively set on two support members 1. Each support mechanism 3 includes two slide rails 31 and two telescopic components 32. The two slide rails 31 are respectively set on both sides of the steel anchor box 100 along the second direction and connected to the support member 1. The two telescopic components 32 are respectively set on both sides of the steel anchor box 100 along the second direction. One end of the telescopic component 32 is adjustablely connected to the slide rail 31 along the second direction, and the other end is rotatably connected to the steel anchor box 100.

[0037] Each drive assembly 22 can independently drive the base plate 21 to move vertically. By controlling the lifting height of the drive assemblies 22 in different adjustment mechanisms 2, the tilt angle of the steel anchor box 100 can be flexibly adjusted, so that it can match the actual angle required by the change of the tower construction height during the storage stage, avoiding repeated adjustments during hoisting, reducing positioning difficulty and shortening the construction cycle. At the same time, in order to ensure the stability of the steel anchor box 100 after the angle is pre-adjusted, one end of the telescopic assembly 32 can be adjusted to a second direction position along the slide rail 31, and the other end is rotatably connected to the steel anchor box 100. It can provide stable support after the angle of the steel anchor box 100 is pre-adjusted to prevent displacement or tilting, and can always maintain an effective connection with the steel anchor box 100 through position sliding and its own telescopic movement during the angle adjustment process, adapting to the support requirements under different tilt angles, and further ensuring the reliability of the preparation before the installation of the steel anchor box 100.

[0038] In this embodiment, the adjustment mechanism 2 includes a base plate 21 and four sets of drive components 22. The base plate 21 is a rectangular plate, and the four sets of drive components 22 are located at the four corners of the rectangular plate.

[0039] In this embodiment, the adjustable angle steel anchor box storage device includes two support mechanisms 3.

[0040] Specifically, such as Figure 1 and Figure 3As shown, the drive assembly 22 includes a lead screw 221 and two adjusting nuts 222. The lead screw 221 is vertically connected to the support member 1. The base plate 21 is movably sleeved on the lead screw 221 in the vertical direction. The two adjusting nuts 222 are respectively disposed on both sides of the base plate 21 in the vertical direction and screwed to the lead screw 221. The lead screw 221 achieves vertical displacement adjustment through threaded transmission, which can accurately match the minute angle requirements of the steel anchor box 100 under the variable cross section and irregular curve of the cable tower, effectively avoiding subsequent hoisting deviations caused by insufficient adjustment accuracy. Moreover, the operator only needs to turn the adjusting nut 222 to drive the base plate 21 to move up and down along the lead screw 221, without relying on complex power equipment, which greatly reduces the difficulty of on-site operation. At the same time, the two adjusting nuts 222 are located on both sides of the base plate 21, which can be locked in both directions to firmly fix the base plate 21 at the target height of the lead screw 221, effectively preventing the base plate 21 from shifting due to vibration, external force and other factors before storage or hoisting, and ensuring the long-term stability of the pre-adjusted angle of the steel anchor box 100.

[0041] More specifically, the drive assembly 22 also includes a pad 223, which is welded to the support member 1 and has a support groove. The lead screw 221 is inserted into the support groove and welded to the pad 223. The support groove can precisely limit the radial displacement of the lead screw 221, preventing the lead screw 221 from shifting or tilting when bearing the weight of the steel anchor box 100 or during adjustment. Subsequently, the lead screw 221 and the pad 223 are welded to further strengthen the connection strength.

[0042] In this embodiment, the pad 223 includes a support portion and four limiting portions, which are circumferentially spaced on the support portion and together form a support groove with the support portion.

[0043] Specifically, such as Figure 1 and Figure 4 As shown, the telescopic assembly 32 includes two threaded adjusting rods 321 and a threaded sleeve 322. The two ends of the threaded sleeve 322 are correspondingly fitted and screwed onto the two threaded adjusting rods 321. One threaded adjusting rod 321 is adjustablely connected to the slide rail 31 along a second direction, while the other threaded adjusting rod 321 is rotatably connected to the steel anchor box 100. The threaded adjusting rods 321 and threaded sleeves 322 are connected by threaded engagement. Operators only need to rotate the threaded adjusting rods 321 or threaded sleeves 322 to precisely change the engagement length using threaded transmission, thereby flexibly adjusting the overall length of the telescopic assembly 32. The threaded structure itself has self-locking properties. Once adjusted to the target length, without active external force rotation, the threaded adjusting rods 321 and threaded sleeves 322 will not slip relative to each other due to the weight of the steel anchor box 100 or external vibrations, maintaining a stable support length for a long time. This provides continuous and reliable lateral constraint force to the steel anchor box 100, preventing lateral displacement of the steel anchor box 100 during storage or angle pre-adjustment.

[0044] Specifically, such as Figure 1 ,like Figure 4 and Figure 5 As shown, each support mechanism 3 also includes two first connectors 33. The two first connectors 33 are connected one-to-one to the ends of the two telescopic components 32 away from the steel anchor box 100. The first connectors 33 are slidably disposed in the groove of the slide rail 31 along the second direction. The first connectors 33 are provided with first connecting holes. The slide rail 31 is provided with a plurality of limiting holes 310 evenly spaced along the second direction. The first connecting hole can be selectively aligned with one of the limiting holes 310 and fixed by a pin. The first connector 33 is slidably disposed in the groove of the slide rail 31 along the second direction, providing a stable sliding guide for the end of the telescopic component 32 away from the steel anchor box 100. This ensures that the telescopic component 32 always moves along the preset trajectory when its position in the second direction changes with the angle adjustment of the steel anchor box 100, avoiding deviation or jamming. At the same time, the multiple limiting holes 310 evenly spaced along the second direction of the slide rail 31 provide a standardized benchmark for the positioning of the first connector 33. According to the actual angle and size requirements of the steel anchor box 100, the operator can accurately align the first connecting hole of the first connector 33 to the corresponding limiting hole 310, realizing multi-position precise positioning of the telescopic component 32 in the second direction. Compared with the sliding adjustment without scale, this greatly improves the accuracy and consistency of position adjustment.

[0045] In this embodiment, the slide rail 31 is provided with eight limiting holes 310 evenly spaced along the second direction, with a 10cm interval between two adjacent limiting holes 310.

[0046] In this embodiment, the slide rail 31 is provided with ten limiting holes 310 evenly spaced along the second direction. The number of limiting holes 310 is not specifically limited here.

[0047] Specifically, such as Figure 4 and Figure 6 As shown, each support mechanism 3 also includes two second connectors 34 and two third connectors 35. The two second connectors 34 are connected to the ends of the two telescopic components 32 away from the slide rail 31 and are provided with second connection holes. The two third connectors 35 are connected to both sides of the steel anchor box 100 along the second direction and are provided with third connection holes. The second connection holes and the third connection holes can be aligned and are provided with pins.

[0048] More specifically, the second connector 34 includes two spaced-apart ear plates 341 with through holes. The two through holes are coaxially aligned to form a second connecting hole. The third connector 35 extends between the two ear plates 341, with the third connecting hole coaxially aligned with the two through holes, and a pin is inserted through it. The two ear plates 341 form a bidirectional clamping effect on the third connector 35, effectively limiting the horizontal displacement of the third connector 35 and preventing it from shaking when subjected to lateral forces from the steel anchor box 100. At the same time, the coaxially aligned through holes and the third connecting hole ensure that the pin is subjected to uniform force, avoiding excessive local force on the pin due to hole position deviation, which could lead to bending or breakage. Furthermore, after the pin is inserted, it can firmly lock the two ear plates 341 and the third connector 35, preventing the connection from loosening during long-term support, and providing a long-term stable guarantee for the connection between the telescopic component 32 and the steel anchor box 100. Furthermore, the spacing structure of the ear plate 341 eliminates the need for complex positioning tools when installing the third connector 35. Simply insert the third connector 35 directly between the two ear plates 341 to quickly align the holes. The pin-through fixing method is also simple to operate. Workers can complete the assembly and disassembly with the help of conventional tools. Whether it is the initial installation or the subsequent refitting during angle adjustment, it can shorten the operation time and improve the efficiency of on-site construction.

[0049] Specifically, the support component 1 includes at least three steel sections 11 connected sequentially along a first direction. These steel sections 11 are smaller and lighter, facilitating transportation to complex sites such as bridge construction sites. Furthermore, on-site assembly can be completed using conventional methods such as bolting and welding, without the need for large hoisting equipment.

[0050] In this embodiment, the support member 1 includes three steel profiles 11 welded sequentially along a first direction.

[0051] In other embodiments, the support member 1 includes four steel profiles 11 welded sequentially along a first direction. The specific number of steel profiles 11 is not limited here.

[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
