Description

Technical Field

[0001] The utility model relates to the technical field of equipment for concrete construction, in particular to a novel induction vibrating rod. Background Technique

[0002] A vibrating rod is a tool used in engineering construction, which can make concrete compactly combined, eliminate phenomena such as honeycombing and pockmarks on the concrete, and improve strength. The vibrating rod is divided according to the method of transmitting vibration, power source, and vibration frequency. When pouring concrete components mixed by a concrete mixer, air bubbles in it must be removed. The vibrating rod is used for vibration to make the concrete compactly combined, eliminate phenomena such as honeycombing and pockmarks on the concrete, so as to improve the strength of the concrete and ensure the quality of the concrete components. During the construction of the bridge deck, after pouring the concrete, due to the dense reinforcement on the bridge deck and the small gap between the reinforcements, the traditional vibrating rod cannot be inserted for tamping, making it difficult to vibrate the concrete; at the same time, voids are most likely to form in the dense part of the reinforcement, and strong vibration is required to make the concrete compact, which brings great difficulties to the construction.

[0003] The Chinese patent (the authorization announcement number is: CN 205116743 U) proposed a concrete vibrating rod. With this concrete vibrating rod, the vibrating depth can be conveniently controlled without consuming a large amount of manpower.

[0004] Although the above patent can detect the insertion depth of the vibrating rod, the concrete is likely to contaminate the vibrating rod, making the scale line unclear and thus affecting the use. To facilitate the construction personnel to understand the current insertion depth of the vibrating rod, we propose a novel induction vibrating rod. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a novel induction vibrating rod. When the vibrating rod is inserted, the metal plate will keep in contact with the upper layer of the concrete. When the rod body is pulled up and down by personnel, the magnetic ring block slides up and down on the inner wall of the rod body, and the access resistance value of the resistance wire will change. By detecting the change of the resistance value, the insertion depth of the rod body can be detected, thus facilitating the construction operation of personnel and solving the problems in the background.

[0029] When the vibrating rod is inserted, due to the large area of the metal plate 2, the metal plate 2 will remain in contact with the upper layer of the concrete. When the operator pulls the rod body 1 up and down, due to the magnetic adsorption between the metal plate 2 and the magnetic ring block 12, the magnetic ring block 12 will slide up and down on the inner wall of the rod body 1. When the magnetic ring block 12 slides up and down, it will drive the insulating ring 17 and the conductive slider 16 to move up and down. When the conductive slider 16 moves up and down along the resistance wire 13, the resistance value of the resistance wire 13 connected will change. A sensor capable of detecting the change in the resistance value of the resistance wire 13 is installed inside the control box, and the sensor for detecting the change in the resistance value sends the signal to the controller for collection. The controller can calculate and analyze the current insertion depth of the rod body 1, and the insertion depth and the vibration time of insertion can be displayed in real time on the display screen. After the vibration is completed, when the construction worker lifts the rod body 1, the metal plate 2 will move downward and reset under the action of its own weight, and at this time the magnetic ring block 12 will also move back to its original position.

[0030] A first conductive rod 20 is fixedly penetrated through the left side of the fixing ring 23, a sliding ring 19 is slidably sleeved on the conductive rod 20, the sliding ring 19 is fixedly connected to the conductive slider 16, a second conductive rod 22 is fixedly penetrated through the right side of the fixing ring 23, a connecting block 18 is fixedly connected to the bottom of the second conductive rod 22, and the top end of the resistance wire 13 is fixedly connected to the connecting block 18.

[0031] When the magnetic ring block 12 moves up and down, the sliding ring 19 will slide up and down along the first conductive rod 20. The first conductive rod 20 and the second conductive rod 22 are electrically connected to a sensor inside the control box that can detect changes in resistance value through wires, thus facilitating wiring.

[0032] The first conductive rod 20 slides through the insulating ring 17, enabling the stable up and down movement of the magnetic ring block 12.

[0033] The connecting pipe 6 is composed of an inner pipe and an outer pipe. The outer pipe sleeves the outside of the inner pipe. A number of isolation strips 11 are fixedly connected between the outer pipe and the inner pipe. A number of wire threading channels 10 are formed between the outer pipe and the inner pipe. The provided wire threading channels 10 facilitate the routing of the connected wires.

[0034] A fixing sleeve 8 is fixedly connected to the top end of the metal plate 2, and a number of locking bolts 3 are threaded through the fixing sleeve 8.

[0036] A number of limiting strips 4 are fixedly connected to the outer surface of the rod body 1. The limiting strips 4 slide through the metal plate 2, enabling the stable up and down movement of the metal plate 2.

[0037] Circular limiting blocks are fixedly connected to both the upper and lower sides of the inner wall of the rod body 1.

[0038] A hand-held handle 5 is fixedly connected to the outer surface of the rod body 1. The provided hand-held handle 5 facilitates the personnel to hold the rod body 1 for concrete vibration operation.

[0039] The outer surface of the hand-held handle 5 is wrapped with an anti-slip rubber sleeve.

[0040] Working principle: When this vibrator is inserted, due to the large area of the metal plate 2, the metal plate 2 will remain in contact with the upper layer of the concrete. When the personnel pull the rod body 1 up and down, due to the magnetic adsorption between the metal plate 2 and the magnetic ring block 12, the magnetic ring block 12 will slide up and down on the inner wall of the rod body 1. When the magnetic ring block 12 slides up and down, it will drive the insulating ring 17 and the conductive slider 16 to move up and down. When the conductive slider 16 moves up and down along the resistance wire 13, the resistance value of the resistance wire 13 connected will change. A sensor that can detect the change in the resistance value of the resistance wire 13 is installed inside the control box. The sensor that detects the change in the resistance value sends the signal to the controller for collection. The controller can calculate and analyze the current insertion depth of the rod body 1. The insertion depth and the vibration time of insertion can be displayed in real time on the display screen. After the vibration is completed, when the construction personnel lift the rod body 1, the metal plate 2 will move downward to reset under the action of its own weight. At this time, the magnetic ring block 12 will also move to reset;

[0041] When the magnetic ring block 12 moves up and down, the sliding ring 19 will slide up and down along the first conductive rod 20. The first conductive rod 20 and the second conductive rod 22 are electrically connected to a sensor inside the control box that can detect changes in resistance value through wires, thereby facilitating wiring. The provided wire threading channel 10 facilitates the routing of the wires that can be easily accessed. The provided hand-held handle 5 facilitates the operator to hold the rod body 1 to perform concrete vibration operations.
