Description
Technical Field
The utility model belongs to the technical field of vibrating devices, and particularly relates to a concrete vibrating rod with adjustable length and rigidity extension.
Background
The concrete vibrating rod is a mechanical device commonly used in constructional engineering, and can convert electric energy into vibration, so that the effects of stirring, vibration resistance and the like are realized.
The concrete vibrating rod is based on the principle that electric energy is converted into mechanical energy, and concrete is stirred by vibration, so that the concrete is fully mixed. The concrete vibrating spear has the effect that when the concrete mixer is used for mixing concrete, the concrete is finely divided due to the vibration during mixing, so that the concrete flows more easily, the concrete caking is reduced, the fluidity of the concrete is improved, and the formability is better.
The vibrating spear that uses at present all adopts the rubber tube to connect at the power cord input for protection power cord and grip, but has brought a problem like this, if need to be to the unable regional construction that is close to of remote place, because the flexible rubber tube of connecting behind the vibrating head can not accurately arrange the vibrating head to the construction area, how to solve above-mentioned technical problem is the object of the study of the person skilled in the art.
Disclosure of utility model
The utility model provides a concrete vibrating rod which can accurately put a vibrating head into a remote construction area at fixed points, has long service life and low failure rate, and is lengthened and adjustable in length.
The length-adjustable rigidity-prolonged concrete vibrating rod comprises a vibrating head, wherein an external thread connector is arranged at the input end of a power line of the vibrating head, one side of the external thread connector is connected with a waterproof connector, the periphery of the external thread connector is connected with a steel pipe in a threaded manner, the power line of the vibrating head is arranged inside the waterproof connector, the outside of the waterproof connector is hermetically connected with an inner hole of the external thread connector, the steel pipe is of a hollow structure, one end of the steel pipe is provided with an internal thread, and the other end of the steel pipe is provided with an external thread; the nominal diameter of the internal thread is the same as the nominal diameter of the external thread pipe and can mutually rotate. According to the utility model, the steel pipe is rigidly connected through the external threaded joint at one end of the vibrating head, so that the steel pipe becomes an organic part of the vibrating head, and the relative ageing resistance and the safety of the steel pipe are far greater than those of the traditional rubber pipe connecting structure.
The vibrating rod has the advantages that the vibrating rod has infinite extension performance for long-distance concrete stirring areas such as tunnels, the vibrating stirring effect is greatly improved, and hollows in the long-distance conveying process are avoided. The steel pipes connected end to end also have the technical effect of protecting the power line.
And a gap exists between the outer diameter of the vibrating head and the outer diameter of the steel pipe, so that the transition is realized by using an inclined plane.
The length of the steel pipe is 1500-3000 mm, the universal adaptability of the steel pipe is improved, and the pipe diameter and length ratio of the steel pipe are optimized.
According to the concrete vibrating rod with the length capable of being adjusted and rigidly prolonged, the steel pipe is rigidly connected through the external threaded connector at one end of the vibrating head, so that the steel pipe becomes an organic part of the vibrating head, the vibrating head is accurately put into a remote construction area at a fixed point, the vibrating axial area is prolonged along with the vibration of the vibrating head, the single vibration area is increased, the technical effect of vibration mixing is improved, and in addition, the relative ageing resistance and the safety of the steel pipe are far greater than those of a traditional rubber pipe connecting structure.
Drawings
The utility model is further described below with reference to the accompanying drawings:
FIG. 1 is a schematic view of a front view of a concrete vibrator with adjustable length and rigid extension in accordance with the present utility model;
FIG. 2 is a schematic diagram of a vibrating head according to the present utility model;
fig. 3 is a schematic view of the structure of the steel pipe according to the present utility model.
Detailed Description
The technical scheme of the patent is further described in detail below with reference to the specific embodiments of fig. 1-3.
The utility model provides a concrete vibrating rod with adjustable length rigidity extension, includes vibrating head 1, vibrating head 1 power cord input is equipped with external screw thread joint 6, and waterproof joint 8 is connected to external screw thread joint 6 one side, and steel pipe 2 is connected to external screw thread joint 6 periphery screw thread, and waterproof joint 8 inside sets up vibrating head's power cord 7, and waterproof joint 8 outside airtight connection external screw thread joint 6 hole, steel pipe 2 are hollow structure, and one end is equipped with internal thread 9, and the other end is equipped with external screw thread 41; the nominal diameter of the internal thread 9 is the same as the nominal diameter of the external thread pipe 4 and can mutually rotate. The structure of the steel pipe 2 is equivalent to the vibration length of the vibration head 1, and the waterproof joint 8 prevents water and impurities from entering the vibration head to influence the service life of the vibration head.
The number of the steel pipes 2 is two or more, and the internal threaded holes 9 of one steel pipe 2 are connected with the external threads 41 of the other steel pipe 3, so that an end-to-end technical structure is formed.
As a structure, preferably, one end of the vibrating head 1 close to the external threaded joint 6 is provided with an inclined surface 5, and one side of the inclined surface 5 close to the external threaded joint 6 is provided with an annular groove 11. The outer diameter of the vibrating head is the same as that of the steel pipe 2, so that the structural stability of the whole concrete vibrating rod is improved.
In order to further improve the structural fastness and control precision of the concrete vibrating rod, the length of the steel pipe is 1500-3000 mm.
While the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes may be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
