Technical Field

[0001] This patent relates to the technical field of concrete vibration, and specifically to a concrete vibration device that is convenient to move. Background Technique

[0002] When pouring concrete components mixed by a concrete mixer, it is necessary to remove the air bubbles and compact the concrete to make it densely combined, eliminate the honeycombing and pockmarking phenomena of the concrete, so as to improve its strength and ensure the quality of the concrete components.

[0019] Next, the technical solutions in the embodiments of this patent will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this patent. Obviously, the described embodiments are only a part of the embodiments of this patent, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this patent without creative efforts shall fall within the scope of protection of this patent.

[0020] Please refer to Figures 1 - 3 , this patent provides a technical solution: a concrete vibrating device that is convenient to move, including a motor 1, a hose 2 and a vibrating rod 3. The motor 1 is electrically connected to an external power source. One end of the hose 2 is sleeved outside the output end of the motor 1, and the other end of the hose 2 is installed with a vibrating rod 3. A transmission steel wire 4 is inserted and installed in the hose 2. Both ends of the transmission steel wire 4 are respectively connected to the output end of the motor 1 and the vibrating rod 3;

[0021] The vibrating rod 3 proposed in this article is a planetary type cement concrete inserted electric vibrating rod, which is prior art. It drives the transmission steel wire 4 to rotate through the motor 1, and then drives the eccentric block in the vibrating rod 3 to rotate through the rotating steel wire 4, so that the vibrating rod 3 generates vibration, vibrates the concrete, and shakes out the air bubbles inside the concrete;

[0022] A cooling mechanism 5 is arranged outside the motor 1. The cooling mechanism 5 includes an oil storage pipe 51, a pump 52, an oil injection pipe 53, an oil outlet pipe 54 and a cooling oil 55. The oil storage pipe 51 is installed on the side wall of the motor 1. The oil storage pipe 51 is filled with the cooling oil 55. A pump 52 is installed at the end of the oil storage pipe 51. The pump 52 is communicated with the inner cavity of the oil storage pipe 51. The pump 52 is electrically connected to an external power source. The output end of the pump 52 is installed with an oil injection pipe 53. The oil injection pipe 53 penetrates the side wall of the hose 2 and is communicated with the inner cavity of the hose 2. One end of the oil outlet pipe 54 is inserted and installed on the side wall of the hose 2, and the other end of the oil outlet pipe 54 is inserted and installed on the upper wall of the oil storage pipe 51;

[0023] Since the transmission steel wire 4 will inevitably collide and rub against the inner wall of the hose 2 during rotation, in order to reduce the heat generated by the friction between the two, prevent the hose 2 from being damaged due to overheating, resulting in concrete entering the hose 2, affecting the movement of the transmission steel wire 4, and causing damage to this device;

[0024] Therefore, this device is provided with a cooling mechanism 5, which pumps the cooling oil 55 in the oil storage pipe 51 into the hose 2 through the pump 52. While lubricating the transmission steel wire 4 with the cooling oil, the heat generated by the friction between the transmission steel wire 4 and the inner wall of the hose 2 is taken away, thereby protecting the hose 2;

[0025] The cooling oil 55 pumped into the hose 2 through the pump 52 will flow back to the oil storage pipe 51 through the oil outlet pipe 54, and then be cooled by the heat dissipation mechanism 6.

[0026] Specifically, a heat dissipation mechanism 6 is provided on the outer side of the oil storage pipe 51. The heat dissipation mechanism 6 includes heat dissipation fins 61 and a fan 62. The heat dissipation fins 61 are installed on the outer side of the oil storage pipe 51, and the fan 62 is electrically connected to an external power supply. The fan 62 is installed on the lower wall of the heat dissipation fins 61;

[0027] The cooling oil 55 flowing back into the oil storage pipe 51 will exchange heat with the outer wall of the oil storage pipe 51. By starting the fan 62, the oil storage pipe 51 can be cooled, and the setting of the heat dissipation fins 61 can accelerate the cooling of the oil storage pipe 51.

[0028] Specifically, a fixing plate 7 is installed on the upper wall of the motor 1, and a handle 8 is installed on the upper wall of the fixing plate 7;

[0029] Because the structure of this device is simple and its weight is relatively light, the staff can directly lift this device through the handle 8, enabling the staff to conveniently move this device.

[0030] Specifically, the oil outlet pipe 54 includes a pipe body 541, a connecting pipe 542, and a filter screen 543. One end of the pipe body 541 is inserted and installed in the hose 2, the other end of the pipe body 541 is installed with the connecting pipe 542, the connecting pipe 542 is inserted and installed on the upper wall of the oil storage pipe 51, and the filter screen 543 is installed in the connecting pipe 542;

[0031] Because when the transmission steel wire 4 rubs against the inner wall of the hose 2, some debris will inevitably be generated. These debris will flow back into the oil storage pipe 51 along with the cooling oil 55, contaminating the cooling oil 55. Therefore, a filter screen 543 is provided in the connecting pipe 542 of this device to intercept the debris.

[0032] Specifically, a rotating shaft 9 is rotatably installed in the middle of the filter screen 543, a fan blade 10 is installed on the outer side of the rotating shaft 9, and a rubber strip 11 is fitted and installed on the lower wall of the fan blade 10. The rubber strip 11 can be fitted to the side wall of the filter screen 543;

[0033] To prevent the filter screen 543 from being blocked and affecting the reflux of the cooling oil 55, a rotating shaft 9, a fan blade 10, and a rubber strip 11 are provided above the filter screen 543. When the cooling oil 55 is flowing back, it will drive the fan blade 10 to rotate, so that the rubber sleeve 11 scrapes and cleans the filter screen 543;

[0034] The pipe body 541 and the adapter pipe 542 are connected by threads, which facilitates disassembly for replacing or cleaning the filter screen 543. Moreover, seals are provided between the pipe body 541 and the adapter pipe 542, between the adapter pipe 542 and the oil storage pipe 51, between the oil storage pipe 51 and the pump 52, between the pump 52 and the injection pipe 53, between the injection pipe 53 and the hose 2, between the hose 2 and the vibrating rod 3, and between the hose 2 and the pipe body 541, which can ensure that there is no leakage of the cooling oil 55.

[0035] Specifically, a sliding cylinder 12 is sleeved on the outer side of the hose 2, and a scraping ring 13 is installed on the inner side wall of the sliding cylinder 12, and the scraping ring 13 is attached to the outer side wall of the hose 2;

[0036] Since concrete also has a certain degree of corrosiveness, the sliding cylinder 12 and the scraping ring 13 are provided on the outer side of the hose 2 of this device, so that the concrete attached to the outer side of the hose 2 can be scraped off by the scraping ring 13, avoiding damage to the hose 2 caused by the corrosion of the concrete.

[0037] Working principle: When using this device to vibrate concrete, start the motor 1, which drives the vibrating rod 3 to vibrate through the transmission steel wire 4 to vibrate the concrete and shake out the air bubbles inside the concrete;

[0038] During this process, the cooling oil 55 in the oil storage pipe 51 is input into the hose 2 through the pump 52. While lubricating the transmission steel wire 4 with the cooling oil, the heat generated by the friction between the transmission steel wire 4 and the inner wall of the hose 2 is taken away, thereby protecting the hose 2;

[0039] The cooling oil 55 pumped into the hose 2 through the pump 52 will flow back to the oil storage pipe 51 through the oil outlet pipe 54, and then be cooled by the fan 62 in the heat dissipation mechanism 6;

[0040] After the vibration is completed, the sliding cylinder 12 on the outer side of the hose 2 can be slid, so that the concrete attached to the outer side of the hose 2 can be scraped off by the scraping ring 13, avoiding damage to the hose 2 caused by the corrosion of the concrete.
