Description

Technical Field

[0001] This application relates to the field of inspection device technology, specifically to an indoor track inspection device. Background Technology

[0002] In modern industrial plants, large warehouses, substations and other indoor locations, track-mounted inspection devices are widely used. These devices typically move along a fixed path via a track system, carrying various detection equipment to perform automated inspections of environmental parameters and equipment status. Track inspection devices using gear and rack transmission have advantages such as precise transmission and strong climbing ability. However, there is a prominent problem in their use: dust and debris easily accumulate in dusty industrial environments. Dust entering the gear meshing area will accelerate gear wear and affect transmission accuracy. Especially under long-term operation conditions, dust accumulation in the rack tooth grooves will change the gear meshing clearance, generate transmission noise, reduce transmission efficiency, and even cause jamming, seriously affecting the service life of the device. Therefore, this application proposes an indoor track inspection device to improve this problem. Utility Model Content

[0003] The purpose of this application is to provide an indoor track inspection device in order to solve the problems mentioned in the background art.

A shaft is rotatably mounted on the movable seat. A spherical gear that meshes with the teeth of a rack is fixed on the shaft. One end of the shaft is connected to a motor mounted on the movable seat. An inspection device is mounted on the bottom of the movable seat. The dust removal mechanism includes two air ducts fixed on a movable base. A wind shaft is coaxially rotatably arranged inside the air duct. Several wind blades are arrayed and fixed on the wind shaft. A spray pipe is connected to the air duct. A linkage is provided on the movable base.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0016] like Figures 1-6 As shown, in some embodiments of this application, an indoor track inspection device is proposed, including an I-beam track 1 with a straight rack 2 fixed at its bottom. The I-beam track 1 is composed of an upper wing plate, a web plate, and a lower wing plate. The straight rack 2 is fixed at the bottom of the lower wing plate and is arranged parallel to it. In actual use, the upper wing plate can be connected to the indoor roof through a suspension member, thereby suspending the I-beam track 1 on the indoor roof and reducing the space occupied on the indoor floor. It also includes: a movable seat 3, which is slidably sleeved on the I-beam rail 1. A shaft 4 is rotatably mounted on the movable seat 3. A spur gear 5 that meshes with the teeth of the rack 2 is fixed on the shaft 4. One end of the shaft 4 is connected to a motor 6 mounted on the movable seat 3. An inspection device 7 is mounted at the bottom of the movable seat 3. Preferably, the inspection device 7 can be a camera or a detection instrument for detecting various parameters (temperature, humidity, and gas). When the motor 6 does work, its output shaft drives the shaft 4 to rotate, thereby driving the spur gear 5 to rotate. Since the rack 2 is fixed on the I-beam rail 1 and does not move, the meshing of the teeth of the rack 2 and the spur gear 5 is used to drive the movable seat 3 to move along the I-beam rail 1, thereby driving the inspection device 7 to perform mobile inspection. The dust removal mechanism 8 includes two air ducts 801 fixed on a movable base 3. A fan shaft 802 is coaxially rotatable inside each air duct 801, and several fan blades 803 are arrayed and fixed on the fan shaft 802. A nozzle 804 is connected to each air duct 801. A linkage 805 is provided on the movable base 3. When the shaft 4 rotates, the linkage 805 drives the two fan shafts 802 to rotate synchronously. Preferably, to make the scheme more reasonable, one end of the air duct 801 is open, and its closed end is fixed to the movable base 3. The free end of the nozzle 804 is arranged parallel to the I-beam rail 1 and faces the rack 2. The two nozzles 804 are located on both sides of the spur gear 5. When the movable base 3 moves along the I-beam rail 1, the linkage 805 drives the two fan shafts 802 to rotate, and the fan blades 803 rotate. 3. The inclined setting, the wind shaft 802, the wind blade 803 and the wind duct 801 form an axial flow fan. When the wind shaft 802 rotates, it draws the outside airflow into the wind duct 801 and sprays it out through the nozzle 804, thereby blowing the rack 2 (the rack 2 is in a fixed state, and indoor dust and impurities are easy to adhere between its teeth), thus blowing away the dust and impurities attached to it. Since the two nozzles 804 are located on both sides of the spur gear 5, no matter which direction the movable seat 3 moves (forward or backward), the airflow sprayed by the nozzles 804 will first blow and remove dust from the rack 2 (the area where the rack 2 and the spur gear 5 are to mesh), ensuring that the two can mesh and transmit stably and effectively, ensuring transmission efficiency and improving its service life. In this solution, by setting a dust removal mechanism 8 on the movable seat 3 that is linked to the walking mechanism, a directional airflow can be generated during the inspection process to continuously blow the area to be meshed of the rack 2, effectively removing accumulated dust and impurities. This ensures that the spur gear 5 and the rack 2 can maintain stable and efficient meshing transmission throughout the entire stroke, which not only improves the reliability of the transmission but also effectively reduces wear and extends the service life of the device in dusty indoor environments.

[0017] like Figure 3 and Figure 6As shown, the specific structure of the linkage 805 of this application is disclosed. The linkage 805 includes a transmission gear 8051 fixed on the shaft 4, and driven gears 8052 fixed on both wind shafts 802. Both driven gears 8052 mesh with the transmission gear 8051. Preferably, the movable seat 3 has a cavity, and the transmission gear 8051 and driven gear 8052 are located in the cavity, preventing them from contacting external dust and impurities, thus ensuring the stability of their transmission meshing. The transmission gear 8051 is larger than the driven gear 8052, which is a case of a larger gear driving a smaller one, thereby achieving a speed-increasing effect. Even if the movable seat 3 moves slowly, it can drive the wind shaft 802 to move quickly. Since the motor 6 drives the shaft 4 to rotate forward or backward, it drives the movable seat 3 to move forward or backward. Therefore, in order to make the scheme more reasonable, the fan blades 803 on the two wind shafts 802 are tilted in opposite directions. This ensures that whether the movable seat 3 moves forward or backward, the wind shaft 802 located in the forward direction of the movable seat 3 can draw the outside airflow into the air duct 801 by utilizing the rotation of the fan blades 803. Then, the airflow is blown onto the area to be meshed by the spur rack 2 through the nozzle 804, thereby achieving the function of dust removal.

[0018] like Figure 2 and Figure 5 As shown, this application discloses a further technical solution for dust removal. First brush plates 9 are provided on both sides of the movable seat 3 and located on both sides of the spur gear 5. The brush tips of the first brush plates 9 overlap and cooperate with the straight rack 2, as shown... Figure 2 Combination Figure 3 As shown, the movable seat 3 has a groove, the spur gear 5 is located in the groove, and the two first brush plates 9 are located at the two ends of the groove opening. Before meshing, the rack 2 is pre-treated (the brush bristles scrape the rack 2), which can effectively remove stubborn dirt attached to the tooth surface of the rack 2, complementing the airflow cleaning. At the same time, when the movable seat 3 is in the stopped state, the two first brush plates 9 can also play a temporary sealing role to prevent large particles of debris from entering the meshing area, thereby improving practicality.

[0019] like Figure 4 and Figure 5 As shown, this application discloses a further technical solution for dust removal. Two ventilation holes 10 are provided through one side of the movable seat 3. The two ventilation holes 10 correspond one-to-one with the two nozzles 804. By providing ventilation holes 10 through the movable seat 3 corresponding to the nozzles 804, airflow can be facilitated to pass through the movable seat 3. This can effectively remove the blown dust and impurities from the area of ​​the movable seat 3 and prevent the cleaned dust from re-entering the transmission area, thereby further ensuring the stability of the transmission.

[0020] like Figure 4 and Figure 5As shown, this application discloses a further technical solution for the movement of the movable seat 3. Rollers 11 are rotatably provided on both sides of the movable seat 3. The two rollers 11 roll and overlap with the top of the lower flanges on both sides of the I-beam rail 1. By setting the rollers 11, the rollers 11 roll and overlap with the I-beam rail 1, which is used to bear the weight of the movable seat 3. At the same time, the rolling contact between the rollers 1 and the I-beam rail 1 avoids the movable seat 3 from contacting the I-beam rail 1, reduces frictional resistance, makes the movable seat 3 run more smoothly, and further ensures the inspection effect.

[0021] like Figure 3 and Figure 4 As shown, this application discloses a further technical solution for the movement of the movable seat 3. Limiting grooves 12 are provided on the top of the lower flanges on both sides of the I-beam rail 1. Two rollers 11 are respectively inserted into the two limiting grooves 12. Preferably, the longitudinal section structure of the limiting groove 12 is V-shaped or trapezoidal. The rollers 11 and the limiting groove 12 are adapted to each other in a rolling manner. By setting the limiting grooves 12, the stability of the movement of the movable seat 3 is ensured, and its deviation and deviation in the non-moving direction are avoided, thereby further ensuring the stability of the operation of the movable seat 3.

[0022] like Figure 5 As shown, this application discloses a further technical solution for the movement of the movable seat 3. The movable seat 3 is provided with a second brush plate 13 on both sides of the roller 11. The brush ends of the second brush plate 13 overlap and cooperate with the limiting groove 12. By setting the second brush plate 13, the limiting groove 12 is specially cleaned to prevent dust from affecting the operation of the roller 11, and to remove dust and debris in the limiting groove 12 in a timely manner to avoid the roller 11 from getting stuck, thereby further ensuring the smooth movement of the movable seat 3.

[0023] like Figure 5 As shown, this application discloses a further technical solution for the movable seat 3. The first brush plate 9 and the second brush plate 13 are both detachable structures and are fixed to the movable seat 3 by the cooperation of screws and screw holes. The first brush plate 9 and the second brush plate 13 are both vulnerable parts, and their bristles are easily worn and damaged. By using the cooperation of screws and nuts for fixing, they can be quickly disassembled and replaced. They can be adjusted or replaced in time according to the wear condition to maintain the best cleaning effect, thereby improving practicality.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application.
