Description

Technical Field

[0001] This utility model relates to the field of concrete vibrator technology, specifically a handheld, eight-way adjustable concrete vibrator. Background Technology

[0002] In the reinforcement project of the new seawall, the facing blocks used 2-ton A-type twisted kingpin blocks, 1.381m high, were prefabricated using a single layer of precast steel molds. After the steel molds were assembled, the blocks were poured in layers, and each layer was vibrated and compacted in four stages: the first stage was poured to the top surface of the lower limbs, the second stage to the middle of the waist, the third stage to the top of the waist, and the fourth stage to the top surface of the structure.

[0003] Currently, vibration operations still rely on conventional handheld vibrators. These vibrators can only vibrate vertically downwards, making it difficult to reach into irregularly shaped formwork structures, such as the waist and lower limb top surfaces of twisted-shape steel molds. Due to the upward angle, the vibrator cannot effectively vibrate these areas. This method easily leads to over-vibration in the middle and under-vibration in the waist and lower limb top surfaces, failing to ensure proper vibration in these areas. Air bubbles are also difficult to expel, resulting in sand spots, sand lines, and air bubbles on the waist and lower limb top surfaces, affecting the surface quality. Therefore, there is a need for a handheld, eight-way adjustable concrete vibrator to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a handheld, eight-way adjustable concrete vibrator, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a handheld, eight-way adjustable concrete vibrator, including a handle, a flexible shaft, a lifting device, an adjustment channel, an end fixing device, and a vibrating head; One end of the flexible shaft is connected to the handle, and the other end of the flexible shaft away from the handle is connected to the vibrating head.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This handheld, eight-way adjustable concrete vibrator features four semi-circular limiting rings welded to the center of the connector screw. A metal corrugated tube surrounds the flexible shaft, with four conduits attached to the inner wall of the corrugated tube serving as the conduit for the steel strands of the lifting device.

[0018] Please see Figure 1-4 A handheld, eight-way adjustable concrete vibrator includes a handle, a flexible shaft 8, a lifting device, a directional channel, an end fixing device, and a vibrating head 11. One end of the flexible shaft 8 is connected to the handle, and the other end of the flexible shaft 8 away from the handle is connected to the vibrating head 11. The directional channel includes a conduit 6 and a corrugated metal tube 7. The corrugated metal tube 7 is sleeved on the outer surface of the flexible shaft 8, and the conduit 6 is set on the inner wall of the corrugated metal tube 7. Four conduits are attached to the inner wall of the corrugated metal tube 7 as conduits for the steel strand 4. Pulling the lifting device will tilt the directional channel outward and achieve angle adjustment. The lifting device includes a circular pull ring 3 and a steel strand 4. The steel strand 4 is installed inside the conduit 6, and the upper end of the steel strand 4 extends out of the conduit 6 and connects to the circular pull ring 3. The end fixing device includes an anchor ring 9 and a clamp 10. The anchor ring 9 is welded to the upper end of the outer surface of the vibrating head 11. Four holes are opened on the anchor ring 9. The clamp 10 is set on the end face of the anchor ring 9 away from the metal corrugated pipe 7. The lower end of the steel strand 4 passes through the hole on the anchor ring 9 to fix the tail end of the lifting device steel strand 4.

[0019] The handle includes a handle 1 and a connector screw 2. The connector screw 2 is fixedly set on the end face of the handle 1 near the flexible shaft 8. The flexible shaft 8 is connected to the handle 1 through the connector screw 2. The flexible shaft 8 is a rubber hose. The connection between the steel strand 4 and the circular pull ring 3 is fixed by a locking buckle. The handle 1 is set to make it convenient for construction personnel to hold. The connector screw 2 can be effectively used to connect to the flexible shaft 8.

[0020] Among them, the circular pull ring 3 includes pull ring 3A, pull ring 3B, pull ring 3C and pull ring 4, and the steel strand 4 includes steel strand 4A, steel strand 4B, steel strand 4C and steel strand 4. The upper ends of steel strand 4A, steel strand 4B, steel strand 4C and steel strand 4 are respectively connected to pull ring 3A, pull ring 3B, pull ring 3C and pull ring 4. By pulling the circular pull ring 3 to tighten the steel strand 4, the vibrating head 11 can be deflected and vibrated.

[0021] Among them, the conduit 6 includes conduit 6A, conduit 6B, conduit 6C and conduit 4. The ends of conduit 6A, conduit 6B, conduit 6C and conduit 4 are all connected to the anchor ring 9. The conduit 6 can effectively limit and protect the steel strand 4.

[0022] The connector screw 2 is equipped with a semi-circular limiting ring 5, which includes a first limiting ring 5A, a second limiting ring 5B, a third limiting ring 5C, and a fourth limiting ring. The first limiting ring 5A, the second limiting ring 5B, the third limiting ring 5C, and the fourth limiting ring are welded and fixed in four directions in the middle of the connector screw 2. The first limiting ring 5A, the second limiting ring 5B, the third limiting ring 5C, and the fourth limiting ring are respectively sleeved on the outer surface of the first conduit 6A, the second conduit 6B, the third conduit 6C, and the fourth conduit. By setting the semi-circular limiting ring 5, the conduit 6 can be effectively limited.

[0023] The clamping piece 10 includes clamping piece 10A, clamping piece 10B, clamping piece 10C, and clamping piece 4. Clamping piece 10A, clamping piece 10B, clamping piece 10C, and clamping piece 4 respectively clamp and fix the ends of steel strand 4A, steel strand 4B, steel strand 4C, and steel strand 4. Through the four clamping pieces 10, they can effectively cooperate with the anchor ring 9 to achieve effective limiting and fixing of the ends of steel strand 4A, steel strand 4B, steel strand 4C, and steel strand 4.

[0024] Working principle: When using, first hold the handle 1 with one hand to make the vibrator head 11 drop vertically into the concrete. Then use the other hand to pull the corresponding circular pull ring 3 according to the direction of the part to be vibrated, so as to tighten the steel strand 4 and adjust the direction of the vibrator head 11. It can be inserted into the space of the irregular template structure, such as the waist and lower limb of the twisted block steel mold, and into the designated part to achieve the vibration of the designated part of the concrete. This ensures that the concrete in the difficult-to-reach parts is vibrated and compacted, and prevents missed vibration.

[0025] Furthermore, by manufacturing lifting devices and directional channels of different lengths, it can be adapted to conventional handheld concrete vibrators of different lengths and specifications. The modification materials are common and easy to process, and the size can be customized according to the actual project situation to meet the needs of different scenarios. This ensures that the concrete in the irregular structure formwork is vibrated and compacted, and only one worker is needed to complete the vibration operation independently. The operation is simple, efficient and convenient.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
