Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a working platform for steel bar binding. Background Technique

[0002] With the development of high-speed railway bridge construction in China, whether the high-speed railway box girder adopts the on-site casting or the full prefabrication production mode, during the construction process of each component of the bridge, it is necessary to bind the steel cage of the box girder. Among them, the binding of the steel cage of the box girder is factory construction. During the binding process of the steel cage, it is necessary to position and fix the steel bars to ensure that the steel bars can form the required shape, so it is necessary to use a steel bar binding platform. However, the construction of each component of the bridge by the cast-in-place method is increasingly restricted by the requirements of the surrounding construction environment and the weather environment. The bound steel bars need to be lifted and transferred by a crane for the pouring link. Therefore, the steel bar binding platform cannot be set indoors. In the related technology, the steel bar binding of the box girder is an outdoor operation. When encountering bad weather, the binding process of the steel bars outdoors will be affected, resulting in a slowdown in the construction progress and an increase in the workload of steel bar handling.

[0003] When binding the steel bar framework, the binding process on both sides is relatively convenient because the operator can directly operate on the ground. However, when binding the middle part of the steel bar framework, the worker needs to climb onto the already erected steel bar framework for binding, which not only increases the difficulty and danger of the operation, but also may cause unnecessary disturbance to the stable position of the steel bars due to the limited operation space and the vibration caused by the body movement, thereby possibly having an adverse impact on the overall construction quality and structural stability.

[0004] Therefore, the utility model provides a working platform for steel bar binding to solve the above problems. Summary of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] The present invention provides a working platform for steel bar binding, as Figure 1 、 Figure 2 and Figure 4 shown. The working platform for steel bar binding includes a bottom plate 1, a binding frame 2 fixedly installed on the bottom plate 1, a plurality of support legs 3 fixedly installed on the bottom plate 1, and a moving mechanism for binding steel bars arranged on the top of the bottom plate 1 through the support legs 3.

[0023] The moving mechanism includes a slideway 4 fixedly installed on the support leg 3, a chute 5 opened on the slideway 4, a roller 6 slidably installed inside the chute 5, a connecting rod 7 fixedly installed inside the two rollers 6, a sleeve rod 8 sleeved on the connecting rod 7, a clamping wheel 9 fixedly installed on the connecting rod 7, a clamping block 10 hinged on the sleeve rod 8, a spring 11 arranged at the bottom of the clamping block 10, a workbench 12 fixedly installed on the sleeve rod 8, and a guardrail 13 fixedly installed on the workbench 12.

[0024] When the user needs to tie steel bars, the device is placed in a suitable place through the bottom plate 1. The steel bars are manually placed on the tying frame 2, and then the steel bars around the tying frame 2 are manually tied. After the steel bars around are tied, the external motor is started, and the rotation of the output end of the motor drives one of the rollers 6 to rotate. Through the action of the connecting rod 7, both rollers 6 rotate. The rollers 6 rotate along the chute 5 opened inside the slideway 4 until they reach the lowest point. The operator stands on the workbench 12 and then ties the steel bars inside the tying frame 2. After tying one place, the operator stands on the top of the workbench 12, holds the guardrail 13 with one hand, and steps on one end of the catch block 10 with the foot. Since the catch block 10 is hinged at the top of the sleeve rod 8, the other end of the catch block 10 will lift from the catch wheel 9 and does not limit the catch wheel 9. Then, the external motor is started to drive the roller 6 to rotate, thereby driving the workbench 12 and the operator standing on it to move together. During the movement, the operator holds the guardrail 13 with one hand to avoid falling from the workbench 12. When the operator reaches the designated working position, since the operator steps on one end of the catch block 10, this action will compress the built-in spring 11 and store elastic potential energy. Once the operator's foot is unloaded and no longer applies pressure, the previously compressed spring 11 will quickly release the potential energy stored inside it, pushing the stepped end of the catch block 10 to bounce upward. Thus, the other end of the catch block 10 will be embedded inside the catch wheel 9. After the catch block 10 is successfully embedded in the catch wheel 9, a mechanical locking state will be formed. This state directly restricts the rotational freedom of the roller 6 and prevents any rotation of the roller 6, thereby ensuring that the workbench 12 can stop steadily at the position required by the operator and providing a stable platform for the next operation, ensuring the stability of the workbench 12 during operation.

[0025] After the workbench 12 stops stably, the operator ties the steel bars distributed in each corner. After tying, the operator stands on the workbench 12 and uses the guardrail 13 on the top of the workbench 12 as a support, gently holding with one hand to ensure body balance; stepping on the catch block 10 with the other foot. Next, with the start of the external motor, the roller 6 is driven to rotate, thereby driving the workbench 12 to move until the workbench 12 reaches the positions on both sides of the slideway 4, and then the firmly tied steel bars are taken out.

[0026] Further, in order to prevent the steel bars from moving when placed on the tying frame 2, as Figure 1 、 Figure 3 and Figure 4 shown, a plurality of longitudinal frames 14 are fixedly connected to the top of the tying frame 2. The longitudinal frames 14 are arc-shaped, and a plurality of transverse frames 15 are fixedly connected between the two longitudinal frames 14.

[0027] A plurality of placement grooves 16 are provided on both the longitudinal border 14 and the transverse border 15. The placement grooves 16 are distributed in a linear array, the placement grooves 16 are U-shaped, and a blocking block 17 is clamped inside the placement grooves 16.

[0028] During the construction process of steel bar binding, when the user is preparing to bind steel bars, first, the steel bars will be arranged orderly within the longitudinal border 14. Here, the longitudinal border 14 is specially provided with placement grooves 16 for accommodating steel bars. If the preset distance between the steel bars is insufficient to meet the construction requirements, or if it is desired to further optimize the steel bar layout to enhance the bearing capacity of the structure, the spacing can be adjusted manually. The user inserts the blocking block 17 into the placement grooves 16. By inserting a blocking block 17 into every other slot position in each placement groove 16, the distance between the steel bars is physically increased, enabling each steel bar to accurately align with the slot positions not occupied by the blocking block 17, and effectively controlling the distance between the steel bars. After completing the layout and spacing adjustment of the steel bars, the next step is to bind the steel bars. When binding the steel bars, ensure that the binding points are evenly distributed and the binding wires or binding filaments are fastened securely to prevent the steel bars from shifting when pouring concrete or under external forces, thereby ensuring the stability and integrity of the entire steel bar framework.

[0029] Among them, in order to prevent the workbench 12 from tilting during movement, as Figure 1 and Figure 4 shown, the blocking block 17 is T-shaped, a moving groove 18 is opened at the top of the bottom plate 1, and a telescopic rod 19 is slidably connected inside the moving groove 18.

[0030] The movable end of the telescopic rod 19 is fixedly connected to the bottom of the sleeve rod 8, and one end of the spring 11 is fixedly installed at the bottom of the block 10.

[0031] The other end of the spring 11 is fixedly installed at the top of the sleeve rod 8, and the end of the block 10 away from the spring 11 meshes with the caster wheel 9.

[0032] In the steel bar binding operation, driven by an external motor, the workbench 12 moves. As the workbench 12 moves downward, the telescopic rod 19 contracts accordingly. This dynamic adjustment mechanism ensures that the telescopic rod 19 can always be accurately positioned and fit against the bottom of the workbench 12. It not only provides support for the workbench 12 but also effectively prevents it from tilting or shaking due to uneven force during movement, further enhancing the stability and safety of the operation and ensuring the smooth progress of the binding operation.

[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
