Description

Technical Field

[0001] The present application relates to the technical field of vibrating rod heads, and in particular to a concrete vibrator for the construction of explosion-proof walls in a central control room. Background Art

[0002] When using the mixed concrete to cast components, in order to ensure the quality and structural strength of the concrete components, a vibrator must be used to remove the bubbles generated inside the concrete components during casting, so that they can be densely combined and the honeycomb surface phenomenon generated therein can be eliminated;

[0003] Vibrators can be divided into two types according to the principle of vibration they produce: eccentric type and planetary type. The eccentric vibrator uses the centrifugal force generated by the eccentric shaft when it rotates at high speed to make the rod body produce circular vibration; while the planetary vibrator uses a shaft suspended at one end, and when it rotates, the conical part of its drooping end rolls along the conical surface in the rod shell, thereby forming a planetary motion of the rolling body to force the rod body to produce circular vibration.

[0004] However, both of these vibration generation methods require contact between the rotating shaft and the rod body, and the rotation speed of the rotating shaft in the vibrator can reach 12000RPM. Therefore, during its high-speed rotation and frictional contact with the rod body, it is very easy to cause severe wear to itself or the inner wall of the rod body, which not only affects the service life of the vibrating rod head on the vibrator, but also with the increase of wear, it is very easy to cause the frequency of its vibration to decrease, the efficiency of removing bubbles in concrete components is reduced, and the quality and structural strength of concrete components are easily deteriorated due to unclean removal of bubbles in concrete components, posing a great safety hazard.

[0005] Therefore, there is an urgent need for a vibrating rod head component for a concrete vibrator to solve the defects of the above-mentioned existing vibrating rod heads of the vibrators during actual use. Summary of the invention

[0006] The present application proposes a concrete vibrator for the construction of explosion-proof walls in a central control room. The invention adopts a non-contact vibration transmission method to force a rod body to generate circular vibration, thereby effectively avoiding the wear problem generated therebetween and having the advantage of high efficiency in removing bubbles in concrete components. The invention is used to solve the problem that a high-speed rotating shaft is very likely to cause severe wear to itself or the inner wall of the rod body during the friction contact with the rod body, which not only affects the service life of the vibrating rod head on the vibrator, but also easily causes its vibration frequency to decrease as the wear increases, and the efficiency of removing bubbles in concrete components becomes poor. The quality and structural strength of concrete components are also very likely to deteriorate due to unclean removal of bubbles in concrete components, posing a great safety hazard.

[0007] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a concrete vibrator for the construction of explosion-proof walls in a central control room, comprising a vibrating rod body, an internal movable sleeve of the vibrating rod body having a connecting shaft extending at one end to its end, a rotating body is arranged on one side of the end of the connecting shaft and located inside the vibrating rod body, a connecting shaft has a connecting hole passing through its left and right ends, and the other end of the connecting shaft is connected to a high-pressure air pump, a first magnet is fixedly installed on one side of the inner wall of the vibrating rod body, a spiral guide groove is provided inside the rotating body, and a second magnet matching the connecting hole on the vibrating rod body is provided on the outer surface of the rotating body.

[0008] Furthermore, the number of the first magnets and the second magnets is set to an even number, and the poles of the first magnets are arranged alternately, while the poles of the second magnets are arranged symmetrically, so that when the rotating body rotates, the two symmetrical groups of first magnets and second magnets attract each other in one group and repel each other in the other group.

[0009] Furthermore, a guide block is fixedly installed at the end of the inner cavity of the vibration rod body, and a conical groove matching the guide block is opened in the spiral guide groove on the rotating body, and a gap space is reserved between the outer surface of the guide block and the conical groove for the vibration rod body to undergo circular vibration.

[0010] Furthermore, a hand-held portion is fixedly sleeved on one side of the outer surface of the connecting shaft, and an end of the hand-held portion contacts one end of the elastic member, and a transmission connection is formed between the vibration rod body and the connecting shaft through the elastic member.

[0011] Furthermore, an inner protrusion is provided in the middle of the inner wall of the vibration rod body, and cooperates with an outer groove opened in the middle of the outer surface of the connecting shaft, and a gap is left between the inner protrusion and the outer groove. Initially, under the elastic force of the elastic part, the side end surfaces between the inner protrusion and the outer groove are squeezed and contacted with each other.

[0012] Furthermore, the left end surface of the inner protrusion is coated with an elastic colloid.

[0013] Furthermore, the exterior of the vibration rod body is configured as a conical structure with a large outer diameter at the front end and a small outer diameter at the rear end, and the rotating body is located at the end with the larger outer diameter.

[0014] The present invention application has the following technical effects:

[0015] The present application provides a concrete vibrator for the construction of explosion-proof walls in a central control room. For the setting of a connecting shaft and a structure thereon, the second magnet in the rotating body thereon can make use of the change in the magnetic poles of the first magnet on the vibrating rod body during rotation, so that two symmetrical groups of first magnets and second magnets, one group attract each other and the other group repel each other, to ensure that the vibrating rod body can produce circular vibration. In addition, a non-contact vibration transmission method is adopted to force the vibrating rod body to produce circular vibration, thereby effectively avoiding the wear problem between the vibrating rod body and the connecting shaft in the prior art. At the same time, the efficiency of removing bubbles in concrete components is high, and the quality and structural strength of the cast concrete components are better.

[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] like Figure 1 , Figure 2As shown, a concrete vibrator for the construction of explosion-proof wall of central control room includes a vibrating rod body 1 which is used to extend into the concrete to generate vibration and remove bubbles generated during pouring. A connecting shaft 2 with one end extending to the end thereof is movably sleeved inside the vibrating rod body 1. A rotating body 4 is movably sleeved inside the vibrating rod body 1 and is located on one side of the end of the connecting shaft 2. Figure 3 , Figure 4 As shown, the interior of the connecting shaft 2 is provided with a connecting hole 10 penetrating the left and right ends thereof, and the other end of the connecting shaft 2 is connected to the high-pressure air pump, and then the high-speed airflow can be delivered to the rotating body 4 through the connecting hole 10 on the connecting shaft 2. A plurality of groups of first magnets 8 arranged in a ring array are fixedly installed on one side of the inner wall of the vibrating rod body 1, as shown in FIG. Figure 5 As shown, a spiral guide groove 11 is provided inside the rotating body 4, and under the impact of the high-speed airflow, the rotating body 4 can be forced to rotate at a high speed. A plurality of groups of second magnets 13 arranged in a ring array and matched with the connecting holes 10 on the vibrating rod body 1 are provided on the outer surface of the rotating body 4. When the rotating body 4 rotates at a high speed, under the attraction or repulsion of the magnetic force between the first magnet 8 and the second magnet 13, the vibrating rod body 1 can be forced to vibrate in a circular manner to remove the bubbles generated inside the concrete component during the pouring, and a non-contact vibration transmission method is adopted to force the vibrating rod body 1 to vibrate in a circular manner, which effectively avoids the wear problem caused by frictional contact between the vibrating rod body 1 and the rotating body 4;

[0026] Among them, the arrangement of the connecting shaft 2, the rotating body 4 and the structure thereon, using high-speed airflow to drive the rotating body 4 to rotate at high speed, can effectively avoid the problems of large power loss and limited transmission distance of the existing vibrator using a soft shaft transmission.

[0027] In the present technical solution, the number of the first magnets 8 and the second magnets 13 are both set to an even number, and the magnetic poles of the first magnets 8 are arranged in a staggered manner, while the magnetic poles of the second magnets 13 are arranged symmetrically. Therefore, when the rotating body 4 rotates, the two symmetrical groups of the first magnets 8 and the second magnets 13, one group attracts each other, and the other group repels each other, to ensure that the vibrating rod body 1 can perform circular vibration.

[0028] like Figure 3 , Figure 5 As shown, in the present technical solution, a guide block 7 is fixedly installed at the end of the inner cavity of the vibration rod body 1, and a conical groove 12 matching the guide block 7 is opened in the spiral guide groove 11 on the rotating body 4, and a gap space for the vibration rod body 1 to undergo circular vibration is reserved between the outer surface of the guide block 7 and the conical groove 12. Then, under the action of the guide block 7 and the conical groove 12, the airflow passing through the rotating body 4 can be guided to flow in the opposite direction along the gap formed by the outer surface of the connecting shaft 2 and the inner wall of the vibration rod body 1, so as to reduce the impact of the high-speed airflow on the end of the vibration rod body 1 and the problem of a decrease in its circular vibration frequency.

[0029] like Figure 1 , Figure 4 As shown, in the present technical solution, a hand-held portion 5 for an operator to use the vibrating rod head of the vibrator is fixedly sleeved on one side of the outer surface of the connecting shaft 2, and the end of the hand-held portion 5 is in contact with one end of the elastic member 3, and a transmission connection is formed between the vibrating rod body 1 and the connecting shaft 2 through the elastic member 3.

[0030] like Figure 2 , Figure 3 as well as Figure 4 As shown, in the present technical solution, an inner protrusion 6 is provided in the middle of the inner wall of the vibrating rod body 1, and cooperates with an outer groove 9 provided in the middle of the outer surface of the connecting shaft 2, and a gap is left between the inner protrusion 6 and the outer groove 9, and at the beginning, under the elastic force of the elastic member 3, the side end surfaces between the inner protrusion 6 and the outer groove 9 are squeezed and contacted with each other, thereby preventing the vibrating rod head in the vibrator from colliding with the inner wall of the vibrating rod body 1 due to shaking when the vibrating rod head in the vibrator is not in operation;

[0031] When the vibrating rod head in the vibrator is working, the airflow can squeeze the inner protrusion 6 on the vibrating rod body 1 and make the gap between them conductive to circulate airflow. At the same time, the gas flowing in the gap can be used to prevent the vibrating rod body 1 from contacting the vibrating rod body 1 when circular vibration occurs, and effectively reduce the discomfort caused to the operator's hands by the vibration transmitted to the operator through the connecting shaft 2.

[0032] like Figure 3 As shown, in the present technical solution, the left end face of the inner protrusion 6 is coated with an elastic colloid with high wear resistance, so that when the vibration rod body 1 is not in operation, the elastic force of the elastic member 3 can effectively improve the sealing performance when the inner protrusion 6 contacts the side end face of the outer groove 9, and prevents external dust and other impurities from easily entering the interior of the vibration rod body 1.

[0033] like Figure 2 As shown, in the present technical solution, the exterior of the vibration rod body 1 is configured as a conical structure with a large outer diameter at the front end and a small outer diameter at the rear end, and the rotating body 4 is located at the end with the larger outer diameter, thereby making the front end mass of the vibration rod body 1 larger and maintaining a relatively vertical state during the process of being lowered into the concrete.
