Description

Technical Field

[0001] The invention belongs to the field of concrete vibrators, and more specifically, designs a retractable, foldable and multi-point extendable vibrator and a construction method. Background Art

[0002] Concrete is often used in construction projects today. When pouring components, a vibrator must be used to remove bubbles from the concrete to achieve a dense combination of concrete and ensure the quality of concrete components. The vibrator uses the eccentric block to rotate and vibrate, resonating with the concrete component to quickly expel bubbles.

[0003] In the prior art, in order to enable the vibrator to quickly pass through the buried steel support during the pouring process, the vibrator is generally in the shape of a vertical long rod, with a small vibrating area. Workers need to frequently insert and remove the vibrator, and the vibration frequency is high, which seriously reduces the efficiency of concrete vibration. In some areas, the steel skeleton is large and the steel gap is small. The diameter of the ordinary vibrator is large and it cannot be inserted into the steel skeleton to reach the lower concrete area. This causes missed vibration or inadequate vibration, affecting the quality of the concrete.

[0004] In the prior art, the flexible device and the expansion liquid used in some designs are easily damaged by sharp objects, resulting in leakage of the expansion liquid and contamination of the concrete. In addition, there are other designs that can improve the density of concrete during the extraction process, but due to their limited vibration range, they can only vibrate at a single point, resulting in low work efficiency.

[0005] The patent of the present invention improves the vibration efficiency by utilizing the method of installing multiple vibrating rods; by setting a vibrating end with a smaller diameter, it can be applicable to various steel frame environments and has a wide range of applications; by setting a retractable vibrating head, it is applicable to the vibration needs of concrete components of different depths. Summary of the invention

[0006] In view of the above defects or improvement needs of the prior art, the present invention provides a retractable, foldable and multi-point expandable vibrating rod and construction method. The invention solves the problems that during the concrete vibration process, a single vibrating rod has low vibration efficiency; the vibrating rod has a large diameter and is difficult to insert into the steel bar gap; and the vibrating rod cannot be adjusted according to the vibration requirements of concrete components of different depths.

[0007] In order to solve the above problems, the present invention proposes a retractable, foldable and multi-point extendable vibrating rod, comprising a straight end, a folding end whose upper end is hinged to the straight end, a vibrating end detachably connected to the straight end or the folding end, and a power device (including a driver and a power connecting pipe) for providing power to the straight end;

[0008] The straight end includes a straight end frame, a straight end rotating screw, a connecting female head, a transmission gear at the left end of the input gear, and a straight end output hole arranged on the outer side of the straight end frame; the number of the straight end rotating screws is not less than two, one end of which is rotatably fixedly connected to the straight end frame through the connecting female head; the other end is provided with a transmission gear, and a gear space that can be matched with the input gear is formed between the transmission gears of the plurality of straight end rotating screws; the input gear is arranged in the gear space, and the outer end of the input gear is fixedly connected to the output end of the power device;

[0009] The number of the folding ends is at least two, and they are hingedly arranged at the two ends of the straight end in a flippable manner, and the middle part thereof forms a channel for the output end of the power device to pass through; each folding end includes a folding end frame, a folding end rotating screw arranged inside the folding end frame, and a connecting male head; the folding end rotating screw is rotatably connected to the folding end frame through the connecting male head; a plurality of folding end output holes are arranged on the outer side of the folding end frame; the folding end can be flipped to the two ends of the straight end and form an extended structure (for example, a rod shape) extending at both ends with the straight end; after reversal, the connecting male head is connected to the connecting female head and forms a force transmission structure that can transmit the circumferential force of the straight end rotating screw (that is, when the straight end rotating screw rotates, the folding end rotating screw is driven to rotate through the force transmission structure)

[0010] The vibrating end is detachably connected to the straight end output hole and the folding end output hole, and obtains power transmission from the straight end rotating screw and the folding end rotating screw to perform vibration operation on the outside (the overall controlled diameter of the vibrating end is controlled at 2-3 cm).

[0011] Furthermore, the vibrating end includes: a vibrator gear, a vibrating end thread, a transmission spring, a pressing spring cap, a transmission rod, an eccentric vibrator, a vibrating head, a limiting hole, and a vibrating end shell; the vibrating end is connected to the straight end output hole and the folding end output hole through a thread, the folding transmission end of the vibrator gear is meshed with the rotating screw 14 and the folding end rotating screw, the vibrator gear of the vibrating end is fixedly connected to the transmission spring, the transmission spring is fixedly connected to the transmission rod, and the transmission rod is fixedly connected to the eccentric vibrator; the limiting holes are symmetrically and evenly distributed on both sides of the vibrating end shell, and the pairs of pressing spring caps are symmetrically distributed on the front end surface of the vibrating head.

[0012] Furthermore, the straight end output hole or the folded end output hole is a hole with internal threads.

[0013] Furthermore, the connecting male head and the connecting female head are respectively two poles of a magnet, and the male head and the female head are fixed by magnetic attraction when connected.

[0014] Furthermore, the other end of the folded end is detachably connected to the side of the straight end via a fixing structure (the fixing structure is preferably a magnet).

[0015] Furthermore, the number of the folding ends can be increased by fixing a connecting female head on the rotating screw of the folding end, fixing a connecting fixture on the side of the folding end, and connecting a rotating shaft at the folding position to increase the number of the folding ends.

[0016] Furthermore, the vibrating end is an eccentric vibrating device.

[0017] Furthermore, the straight end frame and the folding end frame are columns, preferably rectangular parallelepiped, and may also be cylinders or other columns.

[0018] Furthermore, a sealing cap is provided between the vibrating head and the vibrating end frame.

[0019] As another aspect of the present invention, it also relates to a method for implementing a retractable, foldable and multi-point extendable vibrating rod, comprising the following steps:

[0020] Step 1: First determine the depth of concrete that needs to be vibrated; then adjust the contraction state of the vibrating end, adjust the length of the vibrating end, remove the blocking cap of the limit hole at the front end, press the pressing spring cap, pull the vibrating end outward, stretch the transmission spring, and after it is pulled to the appropriate position, insert the pressing spring cap into the new limit hole, and cover the limit hole blocking cap into the limit hole at the rear end to prevent concrete from entering the inside of the vibrating rod;

[0021] Step 2: Connect the foldable end and the straight end according to the actual work needs on site. The foldable end and the straight end are fixed together by a fixture and a rotating shaft. The worker opens the foldable end, disconnects the fixture, and rotates the foldable end through the rotating shaft, and then connects with the straight end after rotation. The male connector on the foldable end and the female connector on the straight end are plugged together and connected. The rotating screw and the rotating screw of the foldable end form a whole;

[0022] Step 3: According to the actual work needs on site, use as many vibrating ends as possible, adjust as many as necessary, and prepare in place;

[0023] Step 4: Install the vibrating end on the straight end and the folding end. Remove the plugging caps on the straight end output hole on the straight end and the folding end output hole on the folding end, screw the threads on the vibrating end into the straight end output hole and the folding end output hole on the folding end, so that the vibrator gear and the rotating screw and the folding end rotating screw are meshed together to form a butt joint;

[0024] Step 5: Start the driver, and the shaft in the connecting hose rotates, driving the input gear to rotate. The input gear is meshed and connected with the right-end transmission gear and the left-end transmission gear. The input gear drives the right-end transmission gear and the left-end transmission gear to rotate, and then the rotating screw and the folding end rotating screw rotate. The rotating screw and the folding end rotating screw are meshed and connected with the vibrator gear, and the rotating screw and the folding end rotating screw drive the vibrator gear to rotate. The vibrator gear is connected to the transmission spring, and the transmission spring is connected to the transmission rod. The rotation of the transmission rod drives the eccentric vibrator to rotate, and the vibrating end generates vibration. Thereby vibrating the concrete;

[0025] Step 6: After use, remove the vibrating end from the straight end, disconnect the folding end from the straight end, rotate the folding end, and fix it to the shaft. Tighten the pressing spring cap on the vibrating end and push the vibrating end back. Put the limit hole blocking cap into the hole.

[0026] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0027] 1. The present invention designs a retractable structure of the vibrating end, so that the vibration device can adapt to various concrete components of different depths. The length of the vibrating end is set according to the depth of the component, which solves the problem of workers' operating errors, construction based on experience, and inadequate bottom vibration. The effect of controlling the vibration effect of the concrete at the bottom of the component and high vibration efficiency is achieved.

[0028] The present invention connects the vibrator gear, the transmission spring, the transmission rod and the eccentric vibrator by arranging a transmission spring. The transmission spring itself has good stretching and contraction properties, which can make the vibrating end extend and contract. While not affecting the transmission of axial force, the vibrating end can adjust its length according to the needs of different environments to meet the use requirements.

[0029] The present invention miniaturizes the diameter of the vibrating end to 2-3 cm, thereby solving the problem that the vibrating rod cannot be inserted into the steel bars and cannot enter the interior of the component in areas with dense steel bars. The present invention achieves the effect of vibrating concrete components with various steel bar densities.

[0030] 2. The present invention is designed with a foldable and elongated folding end, supplemented by a plurality of vibrating ends, so that the installation and disassembly process is simple and no accessories are required. This solves the problem that the vibration area of ​​the vibrating rod is small and repeated single-point vibration is required, thereby increasing the vibration area and improving work efficiency.

[0031] 3. The present invention adopts gear mechanical connection by designing the connection between the input gear and the right end transmission gear, the rotating screw and the folding end rotating screw and the vibrator gear, which has good self-stability, small kinetic energy loss and strong structural stability.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0040] The present invention mainly aims at the deficiencies of the prior art and provides a retractable, foldable and multi-point expandable vibrating rod and construction method, which can be easily installed and dismantled, adapt to various steel frame environments, have a large vibration area and a wide operating range, reduce manpower input, and thus improve work efficiency.

[0041] The present invention mainly solves the problem that in some areas, the steel skeleton is relatively dense and the gap between the steel bars is relatively small. The diameter of the vibrating end of an ordinary vibrating rod is basically about 5 cm, which cannot directly enter the interior of the steel skeleton, resulting in the concrete in the skeleton being unable to be vibrated or vibrated inadequately, affecting the quality of the concrete; or the worker first destroys the steel skeleton, knocks the steel bars to move, and smashes a large hole before inserting the vibrating rod. The present invention miniaturizes the vibrating end and sets the diameter to about 2-3 cm, so that it can be inserted into any steel skeleton (according to the requirements of the steel bar binding specification, the thickness of the steel bar protective layer shall not be less than 2 cm), fully vibrates the concrete in the steel skeleton, and will not affect the overall structure of the steel skeleton, and will not damage the binding and position of the steel skeleton, and will not cause displacement.

[0042] Please refer to Figure 1 The device of the present invention includes a driver 21, a power connecting pipe 22, a folding end 23, a straight end 24, and a vibrating end 25; the driver 21 provides power and transmits it to the straight end 24 through the power connecting pipe 22 (the input gear 16 drives the left end transmission gear 17 and the right end transmission gear 16 to rotate), the vibrating end 25 connects the straight end 24 and the folding end 23, the rotating screw 14 in the straight end 24 and the folding end rotating screw 27 in the folding end 23 drive the vibrator gear 1 in the vibrating end 25 to rotate, and drive the eccentric vibrator 7 to rotate, thereby generating a vibrating force.

[0043] Please refer to Figure 1 Figure 6 According to applicable requirements, the folding end 23 and the straight end 24 can be connected as a whole by using the connecting male head 11 and the connecting female head 12 to connect the rotating screw 14 and the folding end rotating screw 27.

[0044] Please refer to Figure 3 If the working area is large, such as concrete vibration of a large roof, if a traditional vibrating rod is used, the single-point vibration covers a small area, and workers need to do a large number of single-point vibrations, which leads to low work efficiency. According to applicable requirements, multiple vibrating ends 25 can be installed on the straight end output hole 18 and the folding end output hole 26 through the thread 2, so that the vibrating end 25 and the straight end 24 form a whole, and the length is increased. When multiple vibrating ends 25 work at the same time, they can cover a larger area and a wider range, thereby improving work efficiency.

[0045] Please refer to Figure 4 , Figure 5The device of the present invention can adapt to the different thicknesses of various beams and plates. When the beams and plates are thin, a very long vibration device is not required. When the beams and plates are thick, in order to vibrate in place, the vibrating rod must be able to be inserted to the bottom. In order to achieve this requirement, a plurality of connecting telescopic devices are provided in the vibrating end 25. The vibrator gear 1 transmits the axial force, and a transmission spring 3 is provided. By utilizing the material mechanical properties of the transmission spring 3, it can be stretched, compressed, and force can be transmitted. The transmission spring 3 transmits the axial force of the vibrator gear 1 to the transmission rod 5, and then drives the eccentric vibrator 7 to do work to produce a vibration effect. By providing a plurality of limit holes 9, the vibrating head 8 can be extended or shortened. The pressing spring cap 4 plays a limiting role. The blocking cap 6 and the limit hole blocking cap 10 are provided to block the holes to prevent concrete from entering the interior of the vibrating end 25 and affecting the functional use.
