The steel wire rope passes through the gap, and a vibrating rod is installed at the lower end of the steel wire rope. The lifting device drives the vibrating rod to move up and down through the steel wire rope to achieve the vibration of the concrete. For this concrete vibrating auxiliary device, the vibrating rod is prone to shake and shift. When used for structural pouring construction, the moving direction is difficult to control, and it is easy to touch and damage the steel bars, affecting the structural quality.

[0029] Figures 1 to 4An embodiment of the concrete vibrating device of the present utility model is shown. The concrete vibrating device of this embodiment includes a towing cable 1, a vibrating mechanism 2, and a concrete pouring space 3 enclosed by formworks. At the top of the concrete pouring space 3, there is an upper pulley 31, at the bottom there is a lower pulley 4, and outside there is an operating platform 5. The towing cable 1 is wound around the upper pulley 31 and the lower pulley 4. The two ends of the towing cable 1 respectively pass through the side wall of the concrete pouring space 3 and extend above the operating platform 5. The vibrating mechanism 2 is fixed on the towing cable 1 between the upper pulley 31 and the lower pulley 4.

[0030] During use, the operator stands on the operating platform 5, grabs both ends of the towing cable 1 with both hands, and by retracting and releasing the ends of the towing cable 1, the vibrating mechanism 2 is lifted synchronously with the poured concrete to complete the vibrating work. During the process of the operator retracting and releasing the towing cable 1, the towing cable 1 is kept in a tensioned state. Since the vibrating mechanism 2 is fixed on the towing cable 1 between the upper pulley 31 and the lower pulley 4 and moves along with the movement of the towing cable 1, that is, moves along the extending direction of the towing cable 1 between the upper pulley 31 and the lower pulley 4, the moving direction can be controlled, and it is not easy to touch and damage the steel bars in the concrete pouring space 3, avoiding affecting the structural quality of the concrete.

[0031] Furthermore, in this embodiment, a lower turning wheel 6 and an upper turning wheel 7 are provided on the outer side of the concrete pouring space 3 facing the operating platform 5. The towing cable 1 is wound around the lower turning wheel 6 and the upper turning wheel 7. The upper turning wheel 7 is located above the operating platform 5, and the lower turning wheel 6 is located below the operating platform 5, which is used to guide the corresponding end of the towing cable 1 above the operating platform 5 for the operator to grab while standing on the operating platform 5.

[0032] Furthermore, as Figure 1 shown, in this embodiment, hanging rings 11 for the operator to hold are provided at both ends of the towing cable 1. The setting of the hanging rings 11, on the one hand, is convenient for the operator to hold, and on the other hand, it is convenient to be hung at a designated position.

[0033] Furthermore, in this embodiment, hanging rods 51 for hanging the hanging rings 11 are provided on the operating platform 5. After the construction is completed, the hanging rings 11 at both ends of the towing cable 1 can be hung on the hanging rods 51. On the one hand, it is beneficial to maintain the winding relationship between the towing cable 1 and each wheel, and on the other hand, it is convenient for the operator to find and grab.

[0034] Furthermore, as Figure 2As shown in the figure, in this embodiment, the vibrating mechanism 2 includes a steel braided pipe 21 and a vibrating rod 22. The bottom end of the vibrating rod 22 is limited on the traction cable 1. One end of the steel braided pipe 21 is connected to the top end of the vibrating rod 22 and is detachably fixed on the traction cable 1 through a fixing assembly 8. The other end of the steel braided pipe 21 extends to the outside of the concrete pouring space 3 and is used to connect with the power component. The steel braided pipe 21 is fixed on the traction cable 1 through the fixing assembly 8, and the bottom end of the vibrating rod 22 is limited on the traction cable 1, so that the vibrating rod 22 moves along with the traction cable 1, and moreover, large-amplitude deviation and shaking of the vibrating rod 22 are prevented. The upper steering wheel 7 is installed on the formwork at the top of the concrete pouring space 3, and the lower pulley 4 is fixed on the formwork at the bottom of the concrete pouring space 3. The traction cable 1 moves up and down through the upper pulley 31 and the lower pulley 4 and drives the vibrating rod 22 to complete the vibrating work. The upper pulley 31 and the lower pulley 4 change the direction of the end of the traction cable 1 so that it extends above the operation platform 5, and the retracting and releasing operation can be completed by one operator. This vibrating mechanism 2 is a commercially available conventional structure.

[0035] Further, as Figure 2 shown, in the embodiment, the fixing assembly 8 includes a hoop 81 and a fixing sleeve 82. The fixing sleeve 82 is sleeved on the traction cable 1, and the hoop 81 is connected to the fixing sleeve 82 and is clamped on the steel braided pipe 21. The structure is simple and the disassembly and assembly are convenient.

[0036] Further, as Figure 3 shown, in this embodiment, the hoop 81 includes a first arc-shaped hoop body 811 and a second arc-shaped hoop body 812. One end of the first arc-shaped hoop body 811 and the second arc-shaped hoop body 812 is hinged, and the other end is connected through a connecting bolt 813. The steel braided pipe 21 is clamped between the first arc-shaped hoop body 811 and the second arc-shaped hoop body 812, and the first arc-shaped hoop body 811 or the second arc-shaped hoop body 812 is connected to the fixing sleeve 82. This hoop 81 has a simple structure and is convenient for manufacturing and operation.

[0037] Further, in this embodiment, a locking screw 83 is threadedly connected to the side wall of the fixing sleeve 82, and the locking screw 83 abuts against the traction cable 1. The fixing sleeve 82 is locked on the traction cable 1 through the locking screw 83, which is convenient for adjusting the fixing position on the traction cable 1.

[0038] Further, as Figure 2 and Figure 4 shown, in this embodiment, a mesh bag 9 is provided on the traction cable 1, and the bottom end of the vibrating rod 22 is inserted into the mesh bag 9. On the one hand, the mesh bag 9 can limit the bottom of the vibrating rod 22 to reduce or prevent shaking. On the other hand, it is convenient for the removal of the vibrating rod 22. Further, the mesh bag 9 is fixed on the traction cable 1.

[0039] Furthermore, in this embodiment, the central axes of the upper pulley 31 and the lower pulley 4 are located in the same vertical plane. In this way, it is beneficial to keep the traction cable 1 between the upper pulley 31 and the lower pulley 4 in a vertical state.

[0040] After the construction is completed, if the lower pulley 4 is installed within the concrete pouring space 3, there is no need to disassemble it. If the lower pulley 4 is installed below the concrete pouring space 3, it can be disassembled and reused. Since it takes time for the concrete to solidify, the movement of the traction cable 1 will not be affected during a period before the concrete solidifies, and this concrete vibrating device vibrates and constructs during this period.

Any person skilled in the art can make many possible changes and modifications to the technical solution of the present utility model, or modify it into an equivalent embodiment with equivalent changes, without departing from the scope of the technical solution of the present utility model. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall fall within the scope of protection of the technical solution of the present utility model.
