Detailed Description
In the present invention, the use of directional terms such as "upper, lower, left, right" generally means upper, lower, left, right with reference to the accompanying drawings, unless otherwise specified. "inner and outer" refer to the inner and outer contours of the component itself.
Referring to fig. 1 to 2, an embodiment of the present invention provides a construction apparatus for an inner wall base surface of a water pipe, including: the grinding disc 1 is provided with a rough surface 10 capable of being in contact with an inner wall base surface of the water conveying pipeline, so that the grinding disc 1 can grind the inner wall base surface when in contact with the inner wall base surface and rotating automatically; the driving component 3 is used for driving the grinding disc 1 to rotate automatically, so that the rough surface 10 grinds the inner wall base surface; wherein, the rough surface 10 of the grinding disc 1 is also provided with a dust suction port 12 and an air outlet 11; the construction apparatus further includes: the dust collector 9 is connected with the dust suction opening 12 through a dust suction pipe 2 and is used for absorbing ash slag generated when the grinding disc 1 polishes the base surface of the inner wall; and the blower is communicated with the air outlet 11 through an air pipe 7 and is used for blowing hot air to the inner wall base surface after dust is absorbed so as to dry the inner wall base surface.
The water conveying pipeline is used for conveying water resources and is generally made of concrete, the shape of the water conveying pipeline is generally cylindrical, the diameter of the water conveying pipeline is generally 3-5 meters, and the length of the water conveying pipeline is preferably 4 meters.
When the water conveying pipeline is reinforced, firstly, the base surface of the inner wall of the water conveying pipeline needs to be polished; in order to grind the inner wall base surface, the grinding disc 1 is formed with a rough surface 10, and the rough surface 10 may be formed during the manufacturing process of the grinding disc 1 or may be sand paper mounted on the grinding disc 1 at a later stage. When the water pipeline needs to be polished, the rough surface 10 of the grinding disc 1 is in contact with the inner wall base surface of the water pipeline, then the driving part 3 is started, the grinding disc 1 is driven to rotate through the driving part 3, and polishing of the inner wall base surface is achieved.
During grinding, the dust collector 9 is synchronously opened, and ash slag generated in the grinding process enters the dust collecting box of the dust collector 9 through the dust suction opening 12 on the grinding disc 1 through the dust suction pipe 2.
After polishing, the dust collector 9 and the driving part 3 are stopped, the blower is started, and hot air is blown to the inner wall base surface through the air pipe 7 and the air outlet 11 on the grinding disc 1, so that the inner wall base surface is dried. In addition, because the inner wall base surface is dried in a hot air blowing mode through the blower, the dust generated on the inner wall base surface due to drying can be further removed while the inner wall base surface is dried, and therefore the cleanliness of the inner wall base surface is guaranteed. Therefore, after the inner wall base surface is dried, further dust collection and cleaning work is not needed, the construction procedures are reduced, the construction time of the inner wall base surface is saved, the working efficiency is improved, and the water pipe reinforcing and water cut-off maintenance time is shortened.
In addition, because the dust suction port 12 and the air outlet 11 are arranged on the same grinding disc 1, the invention can realize the grinding, dust suction and drying operations of the inner wall base surface of the water pipeline through the same grinding disc 1, compared with the independently arranged drying and heating device, the invention is beneficial to reducing the volume of the construction device and the cost of the construction device, and the construction efficiency of the construction device is improved because the construction parts do not need to be replaced.
In practice, the driving device is generally a motor, such as a brushless motor. When the grinding disc 1 is driven to rotate by a brushless motor, the brushless motor may be arranged, for example, on the side of the grinding disc 1 opposite to said rough surface 10. As shown in fig. 1, the brushless motor is mounted on the top of the grinding disc 1, and the rough surface 10 is located on the bottom of the grinding disc 1. A rotating shaft is coaxially fixed at the center of the grinding disc 1, and the brushless motor is connected with the rotating shaft of the grinding disc 1 through a transmission device, so that the grinding disc 1 can be driven to rotate in an electrified state.
Further, the grinding disc 1 is translated to polish different positions of the inner wall base surface of the water pipeline. The equipment for realizing the translation of the grinding disc 1 can be various, for example, the grinding disc 1 can be automatically driven to move along the inner wall base surface of the water conveying pipeline by arranging a power device, and the translation of the grinding disc 1 can also be manually controlled.
In the preferred embodiment of the present invention, in order to improve the grinding efficiency of the grinding disc 1 and improve the versatility of the construction device, the grinding disc 1 is a flexible grinding disc 1, that is, the grinding disc 1 can be deformed, so that no matter what shape of the inner wall base surface the construction device is used for grinding, the inner wall base surface can be attached to, thereby improving the versatility of the grinding disc 1, and increasing the contact area between the grinding disc 1 and the inner wall base surface, thereby improving the construction efficiency of the grinding disc 1.
Certainly, in order to better adapt to the polishing of the inner wall base surface of the cylindrical water pipe, because the inner wall base surface of the water pipe is a cylindrical surface, the rough surface 10 of the grinding disc 1, which is in contact with the inner wall base surface of the water pipe, can also be an arc surface, and therefore the rough surface 10 of the grinding disc 1 can adapt to and adhere to the inner wall base surface when the inner wall base surface is polished, so that the contact area between the grinding disc 1 and the inner wall base surface of the water pipe is increased as much as possible, and the construction efficiency of the construction device is improved.
In a preferred embodiment of the invention, the translation of the grating disc 1 with respect to the inner wall base surface of the water duct is manually controlled. For this reason, the construction device further comprises a handheld operating rod 5 connected with the grinding disc 1, and during specific construction, different positions of the inner wall base surface can be ground by an operator holding the handheld operating rod 5. In a preferred embodiment of the invention, the hand-held operating rod 5 is hinged with the grinding disc 1 to facilitate the force application operation of the operator.
As described above, the vacuum cleaner 9 is communicated with the suction opening 12 through the suction pipe 2, and the blower is communicated with the air outlet 11 through the air duct 7, and in order to improve the structural compactness of the construction device, the hand-held operation lever 5 is a hollow pipe, and thus both the suction pipe 2 and the air duct 7 can be laid in the hollow pipe. As shown in fig. 1, the air duct 7 and the dust suction duct 2 are led into the handheld operating rod 5 through one side of the handheld operating rod 5 close to the grinding disc 1, and then led out of the handheld operating rod 5 through one side of the handheld operating rod 5 far away from the grinding disc 1, wherein the air duct 7 is connected with an external blower (not shown in the figure), and the dust suction duct 2 is connected with an external dust collector 9. The duct 7 is preferably a high-temperature heat-resistant telescopic duct 7, and the dust suction duct 2 is preferably a hose.
As mentioned above, the diameter of the water pipe is generally 3 m to 5 m, and in order to polish the parts with different heights of the water pipe, in the preferred embodiment of the present invention, a telescopic handle 6 is coaxially installed at one end of the hollow pipe away from the grinding disc 1, and the length between the handheld part of the operator and the grinding disc 1 can be adjusted by the telescopic function of the telescopic handle 6, so as to polish and dust-collect the parts in the water pipe at different positions, so as to improve the construction convenience of the operator.
After finishing polishing and dust collection of the whole inner wall base surface of the water pipeline, the construction device is controlled to switch to enter a drying mode, and in the drying mode, the dust collector 9 stops working, and the grinding disc 1 stops self-rotation. In order to realize the free switching of the construction device under different working modes, in a preferred embodiment of the present invention, a control panel 4 is further mounted on the handheld operation rod 5, and the control panel 4 includes: the gear shifting switch at least comprises two gears; the controller is used for controlling the driving part 3 and the dust collector 9 to start to work and controlling the blower to stop working under the condition that the gear shift switch is switched to a first gear; and under the condition that the gear shift switch is switched to the second gear, the blower is controlled to be started to work, and the driving part 3 and the dust collector 9 are controlled to stop working.
Specifically, the controller is respectively connected with the gear shift switch, the driving component 3, the blower and the dust collector 9 through signals, and can control the operations of the driving component 3, the blower and the dust collector 9 according to different gears of the gear shift switch. Wherein, the driving part 3 and the dust collector 9 are always in synchronous working state, namely, started and stopped simultaneously; and the blower is turned on after the driving part 3 and the cleaner 9 stop operating.
Because the grinding and dust suction actions are carried out simultaneously, and the dust suction opening 12 and the air outlet 11 are both arranged on the rough surface 10 of the grinding disc 1, ash generated in the grinding process can easily enter the air outlet 11 while being absorbed by the dust suction opening 12, and even the blower is damaged in serious cases. In order to solve the problem, in a preferred embodiment of the present invention, a baffle for opening or closing the air outlet 11 is further disposed on the grinding disc 1, and the baffle is a normally closed baffle, and the normally closed baffle is configured to open the air outlet 11 in an opening state of the blower. Therefore, when the blower is not started, the air outlet 11 is in a closed state, so that ash and slag generated in the process of polishing the base surface of the inner wall cannot enter the air outlet 11, and the reliable operation of the blower is favorably ensured. When the blower is turned on, the normally closed baffle can be driven to be opened by wind power generated by the blower, so that hot air is blown to the inner wall base surface. In addition, the baffle is set to be the normally closed baffle, so that an independent baffle control device is not required to be arranged for controlling the opening and closing of the baffle, the device cost is saved, and the control method for opening and closing the baffle is simplified.
The inventor of the present application finds in practice that hot air is blown to the inner wall base surface through the above air outlet 11, which often results in too high local temperature of the inner wall base surface, and causes uneven heating of the inner wall base surface, which is obviously not beneficial to laying of the carbon fiber cloth in the later period. In order to solve the technical problem, as shown in fig. 2, in a preferred embodiment of the present invention, a grille is disposed on the air outlet 11, and the grille is configured to be capable of adjusting a wind direction of hot wind blown from the air outlet 11, so that the hot wind blown from the air outlet 11 is spread to a wider range, local temperature aggregation is avoided, uniformity of a temperature of wind blown out from the air outlet 11 is improved, a bonding strength of subsequent carbon fiber cloth is improved, and a reinforcement construction quality of a water pipe is improved.
In order to further improve the drying efficiency and the heating uniformity of the grinding disc 1 on the inner wall base surface, the grinding disc 1 is circular, the rough surface 10 is circular, and the air outlets 11 are uniformly distributed at intervals along the first circumferential direction of the rough surface 10. Further, the dust suction ports 12 are disposed between the air outlet 11 and the middle portion of the rough surface 10, and are uniformly distributed at intervals in a second circumferential direction of the rough surface 10, and are staggered from the air outlet 11. Therefore, the dust suction effect can be improved, and meanwhile, the ash and slag can be prevented from being accumulated at the air blowing opening.
In a preferred embodiment of the invention, in order to ensure that sufficient power is available to the drive unit 3, the vacuum cleaner 9 and the blower, the construction device is further provided with a separate power supply device 8, which power supply device 8 is typically an energy storage battery. In order to ensure that the power supply device 8 stores sufficient electric energy, the power supply device 8 can be separately arranged, so that the volume of the power supply device 8 can be increased, and the electric energy storage capacity of the power supply device 8 can be increased.
In order to better control the operation of the grinding disc 1, in a preferred embodiment of the invention, said gear change switch comprises three gears. The functions of the first gear and the second gear are the same as those of the previous embodiment, the third gear is a neutral gear, and when the gear selector switch is switched to the neutral gear, the driving part 3, the dust collector 9 and the blower are all stopped.
In addition, in order to better control the temperature and the humidity of the inner wall base surface, the construction device further comprises a temperature and humidity detection element for detecting the temperature and the humidity on the inner wall base surface; and the controller is used for controlling the heating power and the blowing power of the blower according to the temperature and the humidity so as to control the temperature and the humidity on the inner wall base surface within a preset range, so that the carbon fiber cloth is bonded more firmly to improve the construction quality. Wherein, the predetermined temperature can be, for example, 15 to 30 ℃; the predetermined humidity may be, for example, 15 to 50%.
The controller may be, for example, a controller provided on the control panel 4, and the temperature and humidity detecting element may be, for example, mounted on the grinding disc 1, preferably on the side of the grinding disc 1 where the rough surface 10 is located. The temperature and humidity detecting element can be, for example, a temperature and humidity sensor, and the controller is in signal connection with the temperature and humidity sensor and the blower, so that the heating power and the blowing power of the blower are adjusted according to the temperature value and the humidity value detected by the temperature and humidity sensor, and the air outlet temperature and the air outlet volume of the air outlet 11 are controlled.
In order to improve the construction effect of the above construction device, in a preferred embodiment of the present invention, the grinding disc 1 is provided with an illuminating lamp, and the lamp strip is installed along the outer circumference of the grinding disc 1. Therefore, when the inner wall base surface of the water conveying pipeline is polished, dust is absorbed and dried, the area to be constructed of the inner wall base surface can be illuminated through the lamp strip, and therefore the operation personnel can conveniently perform construction operation better.
The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Within the scope of the technical idea of the invention, many simple modifications can be made to the technical solution of the invention. Including each of the specific features, are combined in any suitable manner. The invention is not described in detail in order to avoid unnecessary repetition.
