Description

Technical Field

[0001] The embodiments of this utility model belong to the technical field of steel strand laying operation, and more specifically, relate to an anti-sway device for steel strand laying operation. Background Technology

[0002] In the current process of laying out steel strands, the lack of effective restraint measures leads to problems such as violent swaying and tangling. In actual construction scenarios, steel strands are often stored in coils. During laying, due to inertia, the steel strands in the coils are released rapidly, which can easily cause large-scale swaying. When multiple steel strands are laid out simultaneously, the mutual friction and interference between them further increase the probability of tangling.

[0003] These problems not only lead to low efficiency in wire laying, but also, taking a prestressed bridge construction project as an example, frequent rework using traditional wire laying methods has resulted in an average delay of 15%-20% in the construction period. Furthermore, the need for workers to get close to adjust the wires poses safety hazards such as impacts, collisions, and entanglements. According to industry safety accident statistics, approximately 30% of work-related injuries during steel strand construction stem from uncontrolled swinging during the wire laying process. In addition, manually adjusting and winding the steel strands requires a significant investment of manpower, with labor costs for a single rework reaching 2-3 times that of normal wire laying operations, posing multiple challenges to project progress management, safety control, and cost control.

[0004] Therefore, there is an urgent need for a steel strand laying operation anti-sway device that can effectively limit the swing amplitude of the steel strand, avoid tangling and knotting during the laying process, ensure the personal safety of construction personnel, and greatly improve the laying efficiency. Summary of the Invention

[0005] In view of the problems that existing steel strand laying operations are prone to, such as violent swaying leading to tangling, knotting, laying jams, low efficiency, and potential injury to workers, this utility model provides an anti-sway device for steel strand laying operations to solve these problems.

[0006] To achieve the above objectives, this utility model provides an anti-sway device for steel strand unwinding operations, comprising a front fixing bracket located at the front end of the coil, which includes a first stop bar and a front limiting frame; multiple first stop bars are provided; the front limiting frame is formed by sequentially fixing the front ends of the first stop bars to corresponding positions on the body of another first stop bar; a rear fixing bracket located at the rear end of the front end of the coil for limiting, the structure of which is the same as that of the front fixing bracket; a longitudinal anti-detachment bar that fits against the outer ring of the coil for limiting, the two ends of which are fixedly connected to the first stop bar and the second stop bar respectively; and a wire pulling anti-sway frame located at the middle of the front end of the front fixing bracket, which includes a support rod and a wire outlet, multiple sets of support rods, the tail ends of which are fixedly fixed to the front limiting frame, and the wire outlet is a ring structure, the rear side of which is fixedly connected to the front end of the support rod.

[0007] Furthermore, the center point of the front limiting frame coincides with the central axis of the wire coil, and its area is smaller than the area of ​​the inner circle of the wire coil; the length of the longitudinal anti-detachment rod is greater than the width of the wire coil; and the lengths of the first stop bar and the second stop bar are greater than the radius of the wire coil.

[0008] Furthermore, the front and rear ends of the longitudinal anti-detachment rod are respectively locked and fixed to the corresponding first stop and second stop through scaffold cross couplers.

[0009] Preferably, the first support bar has four members, which are made of ordinary scaffolding steel pipes.

[0010] Preferably, the first stop bar, the second stop bar, and the longitudinal anti-detachment bar are all made of scaffolding steel pipe with a diameter of 48.3 mm, a wall thickness of 3.5 mm, and a length of 1.5 meters.

[0011] Preferably, the support rod is made of 16mm diameter threaded steel, and the outlet is made by bending a 16mm diameter steel bar into a circle with a diameter of 600mm.

[0012] Preferably, the front fixed bracket, the rear fixed bracket, the longitudinal anti-detachment rod, and the anti-sway wire frame are all provided with an elastic buffer layer, which is made of rubber or sponge.

[0013] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects:

[0014] (1) The anti-sway device of this utility model limits the front and rear ends of the wire coil by the front / rear fixed bracket, constrains the outer ring of the wire coil by the longitudinal anti-detachment rod, and guides the lead-out steel strand by the wire pulling anti-sway bracket, forming a multi-layer limiting structure, which effectively suppresses the violent swaying of the steel strand caused by inertial release and avoids the problem of mutual friction and tangling when multiple wires are released.

[0015] (2) The anti-sway device of this utility model is a limit steel frame customized according to the specifications of the steel wire coil, which can effectively limit the swing amplitude and solve the problems of entanglement, knotting and wire jamming caused by violent swing from the root, ensuring that the steel strand remains stable during the release process and improving the wire release quality; at the same time, it adopts a detachable modular design, and limit components of different sizes can be quickly assembled and replaced to adapt to various construction scenarios.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] like Figures 1-6 As shown, this utility model provides an anti-sway device for steel strand laying operations, including a front fixing bracket 1, a rear fixing bracket 2, longitudinal anti-derailment rods 3, and a wire-pulling anti-sway frame 4. The front fixing bracket 1 is located at the front end of the wire coil 6, and includes four first stop rods 102. The front ends of the first stop rods 102 are vertically fixed to the body of another first stop rod 102 in sequence, thereby forming a square front limiting frame 101. The rear fixing bracket 2 is located at the rear end of the wire coil 6, and its structure is the same as that of the front fixing bracket 1, including a rear limiting frame 201 and a second stop rod 202. The longitudinal anti-derailment rods 3 are arranged in four parallel groups, and the body of the longitudinal anti-derailment rods 3 is connected to the outer edge of the wire coil 6. The ring fits together to limit the movement, and the two ends of the rod are fixedly connected to the first stop rod 102 and the second stop rod 102 respectively; the anti-sway frame 4 is fixedly installed at the middle of the front end of the front fixed bracket 1, and includes a support rod 401 and a cable outlet 402. The support rod 401 is provided in four sets, and its tail end is fixedly installed on the front limit frame 101 respectively. The cable outlet 402 is a ring structure, and its rear side is fixedly connected to the front end of the four sets of support rods 401 respectively, thereby forming a cage structure to limit and guide the lead-out steel strand 7. The swinging device of this utility model uses a front fixed bracket 1 and a rear fixed bracket 2 to block and limit the front and rear ends of the wire coil 6, a longitudinal anti-detachment rod 3 to limit the outer ring of the wire coil 6, and a wire-pulling anti-swing bracket 4 to limit and guide the lead-out steel strand 7. This effectively limits the swinging amplitude of the steel strand, avoids tangling and knotting problems during the wire unwinding process, effectively reduces the frequency of workers approaching the wire coil 6 to adjust the steel strand 7, and reduces the safety risks caused by the springing of the steel strand 7.

[0027] like Figure 1 , 3 As shown, the front fixed bracket 1 is located at the front end of the wire coil 6 and can block and limit the steel strand 7 at the front end of the wire coil 6 to prevent the steel strand 7 from being released quickly due to inertia and causing danger to the workers in front. At the same time, it effectively prevents excessive swing amplitude from causing entanglement and knotting. It includes a first stop bar 102 and a front limit frame 101.

[0028] The first stop bar 102 has four bars, which are made of ordinary scaffolding steel pipes and their length is greater than the radius of the wire coil 6. Furthermore, the first stop bar 102 is made of scaffolding steel pipe with a diameter of 48.3 mm, a wall thickness of 3.5 mm, and a length of 1.5 meters.

[0029] The front limiting frame 101 blocks and limits the steel strand 7 of the inner ring at the front end of the wire coil 6. It forms a square frame by being vertically fixed to another first stop bar 102 in sequence at the front end of the first stop bar 102. The center point of the front limiting frame 101 coincides with the central axis of the wire coil 6, and its area is smaller than the area of ​​the inner ring of the wire coil 6.

[0030] When making the front fixing bracket 1, four steel pipes are used. The front end of one of the steel pipes is welded and fixed to the corresponding position of another steel pipe. After completion, the remaining steel pipes are welded in sequence so that the four steel pipes are welded together as one, and a square frame is formed in the center.

[0031] The front fixing bracket 1 is located at the rear end of the structural wire coil 6 to block and limit the steel strand 7 at the rear end of the wire coil 6, preventing the steel strand 7 from being released quickly due to inertia and causing danger to the workers behind. At the same time, it effectively prevents excessive swing amplitude from causing entanglement and knotting. It includes a rear limiting frame 101 and a second stop bar 102.

[0032] The second stop bar 102 is made of ordinary scaffolding steel pipes, just like the first stop bar 102. It is formed by welding four steel pipes together to form a square rear limit frame 101 in the center.

[0033] The longitudinal anti-derailment rod 4 limits the outer ring of the wire coil 6, preventing the steel strand 7 of the outer ring of the wire coil 6 from being released quickly due to inertia and causing injury to surrounding workers. At the same time, it effectively prevents excessive swing amplitude from causing entanglement and knotting. There are 4 longitudinal anti-derailment rods 4 arranged parallel to each other in the longitudinal direction, which are respectively attached to the outer ring of the wire coil 6. The front and rear ends of the longitudinal anti-derailment rod 4 are fixedly connected to the rear ends of the corresponding first stop rod 102 and second stop rod 202, respectively.

[0034] Furthermore, the longitudinal anti-detachment rod 4 is made of ordinary scaffolding steel pipe, and its length is greater than the width of the wire coil 6; preferably, the longitudinal anti-detachment rod 4 has a diameter of 48.3mm, a wall thickness of 3.5mm, and a length of 1.5 meters.

[0035] like Figure 5 As shown, in order to achieve a quick fixed connection between the longitudinal anti-detachment bar 4 and the front fixed bracket 1 and the rear fixed bracket 2, a scaffold cross coupler 5 is provided to lock and fix the front and rear ends of the longitudinal anti-detachment bar 4 to the corresponding first stop bar 102 and second stop bar 202 respectively.

[0036] When performing limit operations on different specifications of wire coils 6, the scaffold cross coupler 5 can be adjusted to the connection position of the longitudinal anti-slip rod 4 and then quickly locked and fixed. This allows the device to be adapted to anti-swaying wire coil 6 anti-slip wire laying operations of various specifications and can effectively improve the installation efficiency of the device.

[0037] The anti-sway frame 4 guides and limits the outgoing steel strand 7 to prevent it from coiling out during the outgoing process, thus preventing stress release, violent swinging, tangling, and other problems. It includes support rods 4011 and outlet 402. The support rods 401 are provided in four sets, with their tail ends fixed at the four corners of the front limiting frame 101. The outlet 402 is a ring structure, with its rear side fixedly connected to the front ends of the four sets of support rods 401, thereby forming a cage-like structure to limit and guide the outgoing steel strand 7 and prevent it from being pulled out in a coil.

[0038] Preferably, the support rod 401 is made of threaded steel with a diameter of 16mm, and the outlet 402 is made by bending a 16mm diameter steel bar into a circle with a diameter of 600mm.

[0039] When installing and laying out the anti-sway device of this utility model, ordinary scaffolding steel pipes are used to weld together to form a front fixed bracket 1 and a rear fixed bracket 2. A wire pulling anti-sway bracket 4 is welded at the center of the front fixed bracket 1. The front fixed bracket 1 and the rear fixed bracket 2 are placed at the front and rear ends of the wire reel 6, respectively. The front and rear ends of the longitudinal anti-detachment rod 4 are locked and fixed to the corresponding first stop rod 102 and second stop rod 202, respectively, using scaffolding cross fasteners 5. The steel strand 7 is pulled out from the inner circle of the wire reel 6, and the end of the steel strand 7 passes through the front limit frame 101 and the outlet 402 in sequence for the next laying out work.

[0040] In another embodiment of the present invention, the shape of the front limiting frame 101 of the front fixed bracket 1 can be a triangular frame or other polygonal frame, and the corresponding number of the first stop bar 102, the second stop bar 102, the longitudinal anti-detachment bar 3 and the support bar 401 are selected according to the number of sides of the front limiting frame 101.

[0041] Preferably, in another embodiment of the present invention, the front fixed bracket 1, the rear fixed bracket 2, the longitudinal anti-detachment rod 3 and the wire pulling anti-sway bracket 4 are all provided with an elastic buffer layer. The elastic buffer layer is made of rubber or sponge to eliminate the impact force when the steel strand 7 is released inertia, reduce the violent swing when pulling and releasing the wire, and effectively reduce the occurrence of problems such as tangling and knotting.

[0042] The anti-swaying device of this utility model limits the front and rear ends of the wire coil by front / rear fixed brackets, constrains the outer ring of the wire coil by longitudinal anti-detachment rods, and guides the lead-out steel strand by a wire pulling anti-swaying frame, forming a multi-layer limiting structure. This effectively suppresses the violent swaying of the steel strand caused by inertial release and avoids the problems of mutual friction and tangling when multiple wires are unloaded.

[0043] The anti-sway device of this utility model consists of a limiting steel bar frame customized according to the 6 specification of the steel wire coil. It can effectively limit the swing amplitude and solve the problems of entanglement, knotting, and wire jamming caused by violent swing from the root, ensuring that the steel strand remains stable during the release process and improving the wire release quality. At the same time, it adopts a detachable modular design, and the limiting components of different sizes can be quickly assembled and replaced to adapt to various construction scenarios.

[0044] In terms of cost control and practicality, the anti-sway device of this utility model uses steel pipes and steel bars commonly found on construction sites as the main body of the device. It can be made through simple processes such as cutting and welding, without the need for professional processing equipment. The materials are easy to obtain and the production cost is low. Its reinforced steel bar connectors and rust-proof steel pipe structure support long-term repeated use, which significantly reduces the cost of a single operation. The lightweight frame design with quick-release buckles allows for quick installation and disassembly by a single person, greatly reducing manpower input and equipment dependence.

[0045] This utility model's anti-sway device offers several advantages in terms of safety and efficiency. It can be quickly deployed at key points along the cable laying path, significantly reducing the frequency of workers needing to approach hazardous areas to adjust the steel strands. Through multi-directional limiting and an elastic buffer layer, it effectively absorbs the impact force during cable release, avoiding safety hazards such as collisions and entanglements caused by the cable's swinging motion. The standardized installation process simplifies the cable laying procedure to three steps: "positioning-fixing-releasing." Combined with an adjustable limiting distance design, cable laying efficiency is increased by over 60%, effectively shortening the construction cycle and reducing delays caused by rework.
