Description

Technical Field

[0001] The present invention relates to the technical field of tunnel detection, and particularly to a data monitoring and transmitting vehicle with a telescopic arm. Background Art

[0002] During the tunnel construction process, with the continuous expansion of the construction scale and the continuous development of construction techniques, the cross-sectional dimensions of tunnels are increasing day by day, and the excavation height of some tunnels has reached 10 meters or even higher. At the construction sites of such large-section tunnels, the traditional manual inspection and on-site management methods are difficult to meet the needs of construction safety management and construction quality control. Especially during the construction process, construction workers and the project center cannot achieve close-range, multi-angle, and real-time observation of the construction section and the construction site, resulting in untimely feedback of on-site situations and incomplete information transmission, thus seriously affecting the accuracy of construction decisions and the controllability of the construction process. Therefore, there is an urgent need to improve the visual management level and information-based decision-making ability of tunnel construction sites through more intelligent and integrated monitoring means.

[0003] Currently, at tunnel construction sites, common construction equipment is various types of construction machinery, which generally have adverse factors such as strong vibration, large amplitude of boom movement, and high environmental dust concentration during operation. Under such working conditions, if traditional monitoring equipment is installed on the construction machinery boom, it is extremely easy to cause serious shaking of the monitoring screen, blurred images, easy occlusion of the lens, and frequent adjustment of the viewing angle, with a high equipment failure rate, seriously restricting the monitoring effect at the construction site. To solve the above problems, some construction sites adopt the method of installing observation equipment on fixed vertical poles to achieve relatively stable observation of the site. However, this solution has obvious limitations during the gradual excavation of the tunnel: as the construction surface continues to advance, the vertical pole equipment needs to be frequently disassembled and reinstalled, increasing a large amount of manual work, and the stability of the equipment after installation is insufficient. Summary of the Invention

[0004] The present invention discloses a data monitoring and transmitting vehicle with a telescopic arm, which improves the convenience during tunnel detection to at least partially solve the above technical problems.

[0008] Preferably, the driving component includes an electric push rod; the vertical telescopic component includes a base, a first cylinder, a second cylinder and a third cylinder. Among them, the base is installed on the inner bottom wall of the shelter; the first cylinder is installed on the base, and the inside of the first cylinder is hollow and the upper end is open; the second cylinder is vertically slidably inserted into the first cylinder, and the inside of the second cylinder is hollow and the upper end is open; the third cylinder is vertically slidably inserted into the second cylinder; the electric push rod is arranged on the base, the piston rod of the electric push rod extends vertically, and the top of the piston rod of the electric push rod is connected to the top of the first cylinder; the rotating mechanism is arranged between the first cylinder and the telescopic arm mechanism.

[0009] Preferably, the rotating mechanism includes a rotation driving component and a rotating component. Among them, the rotating component includes an upper turntable, a lower support column, a rotating column and a rolling bearing.

[0010] Preferably, the rotation driving component includes a driving box, a rotating motor and a gear. Among them, the driving box is fixedly installed on the outer peripheral wall of the lower support column, the rotating motor is arranged in the driving box, and the gear is coaxially arranged on the output shaft of the rotating motor; a toothed ring is arranged on the outer periphery of the upper turntable, a driving hole is opened on the side wall of the driving box, and a part of the gear extends out of the driving hole and meshes with the toothed ring.

[0011] Preferably, the telescopic arm mechanism includes a top seat, a first multi-stage cylinder, and a second multi-stage cylinder. The top seat is installed on the top of the rotating mechanism. The first multi-stage cylinder extends horizontally and is arranged on one side of the top seat. The second multi-stage cylinder extends horizontally in a direction away from the first multi-stage cylinder and is arranged on the other side of the top seat, and the first multi-stage cylinder and the second multi-stage cylinder are coaxially arranged; the maximum extended length of the first multi-stage cylinder is less than the maximum extended length of the second multi-stage cylinder.

[0012] Preferably, the monitoring mechanism includes a first camera, a second camera, and a lighting member. The first camera is arranged at the end of the piston rod of the first multi-stage cylinder. The second camera and the lighting member are both arranged at the end of the piston rod of the second multi-stage cylinder.

[0013] Preferably, a shielding portion is provided on the outer periphery of the driving hole on the driving box. A meshing space for shielding the meshing portion of the shielding gear ring and the gear is formed within the shielding portion, and the meshing space is communicated with the driving hole; a dust blowing and temperature reducing mechanism is provided on the driving box. The dust blowing and temperature reducing mechanism is used to blow out the dust in the meshing teeth gap of the gear ring when the meshing teeth of the gear ring enter the meshing space, and at the same time take away the heat in the driving box.

[0014] Preferably, the dust blowing and temperature reducing mechanism includes a blowing component and a guiding component, where the blowing component includes a blower, a blowing hose, and a blowing hard pipe. The blower is installed on the outer wall of the driving box. Two blowing hoses are provided and are both communicated with the blowing end of the blower. The blowing hard pipe is installed on the top edge of the driving box. The top end of the blowing hard pipe is communicated with the blowing hose, and the bottom end is vertically downward. Before the meshing teeth of the gear ring enter the meshing space, the blowing hard pipe blows cold air into the meshing teeth gap of the gear ring to blow the dust in the meshing teeth gap of the gear ring away from top to bottom; the guiding component includes a vertical guiding pipe, an arc guiding pipe, and a branch pipe. The arc guiding pipe is arranged inside the driving box. One end of the arc guiding pipe is located on the first outer side of the driving box and arcs upward. The other end of the arc guiding pipe is located on the second outer side of the driving box and horizontally faces away from the driving box. The vertical guiding pipe is communicatively arranged at one end of the arc guiding pipe and is vertically opposite to the blowing hard pipe. A plurality of branch pipes are communicatively arranged on the pipe section of the arc guiding pipe inside the driving box, and each branch pipe inclines toward the side close to the vertical guiding pipe, so that the dust is not easily removed from the branch pipe when flowing in the arc guiding pipe following the fluid.

[0015] The technical solution adopted by the present invention can achieve the following beneficial effects: The present invention realizes the flexible arrangement and dynamic adjustment of the monitoring device in three-dimensional space by setting a vertically liftable lifting arm mechanism, a horizontally telescopic telescopic arm mechanism and a supporting rotating mechanism on the vehicle body, and can realize multi-angle, short-distance and stable observation in the complex construction environment inside the tunnel. At the same time, the monitoring mechanism can be positioned at different positions as the telescopic arm moves, which helps to improve the comprehensiveness and real-time performance of image acquisition, provides rich and reliable data support for construction site management and decision-making, improves the problems of inconvenient movement and unstable picture of traditional pole equipment to a certain extent, and improves the convenience during tunnel detection; Since there is dust in the tunnel and the gear ring is exposed outside the upper turntable, the floating dust can easily enter the meshing tooth clearance of the gear ring. When the gear ring with dust meshes with the gear, it will increase the wear between the gear ring and the gear and reduce the service life. Therefore, after forming a meshing space outside the drive box through the shielding part, before the gear ring enters the meshing space, start the blower, so that the wind force of the blower enters the hard air duct through the flexible air duct, and finally blows out from the hard air duct. The meshing tooth clearance of the rotating gear ring will pass through the wind force part blown out from the hard air duct. Under the action of the wind force, most of the dust remaining in the meshing tooth clearance of the gear ring will be blown away and enter the vertical duct along the direction of the wind force flow, and then be discharged to a direction away from the gear ring through the arc-shaped duct. In this way, the excess dust can be blown away without being scattered around the gear ring, reducing the possibility that the blown-away dust adheres to the meshing tooth clearance of the gear ring again. At the same time, when the fluid with dust passes through the arc-shaped duct, due to the existence of the branch pipe, the heat in the drive box can enter the arc-shaped pipe through the branch pipe, and then be discharged from the drive box along with the fluid with dust, improving the heat dissipation effect in the drive box. And because the branch pipes are all inclined towards the side close to the vertical duct, the dust is not easy to move from the branch pipe into the drive box when flowing in the arc-shaped duct with the fluid. In this way, the dust in the meshing tooth clearance of the gear ring can be effectively removed, and the heat in the drive box can be reduced incidentally, improving the heat dissipation effect.

Detailed implementation manners

[0019] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope protected by the present invention.

[0020] The terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of this application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and do not limit the number of objects. For example, the first object can be one or more. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / ", generally indicates that the related objects before and after are in an "or" relationship.

[0021] The following combines the attached Figures 1 to 5 , and a data monitoring and transmitting vehicle with a telescopic arm provided by this application is described in detail through specific embodiments and their application scenarios.

[0022] A data monitoring and transmitting vehicle with a telescopic arm, combined with Figure 1 , which includes a vehicle body 100, a lifting arm mechanism 200, a telescopic arm mechanism 300, a rotating mechanism 400, and a monitoring mechanism 500. Among them, the vehicle body 100 can move along the tunnel. Exemplarily, the vehicle body 100 can travel inside the tunnel and can adopt a crawler-type or wheel-type drive structure to adapt to the tunnel ground conditions under different geological conditions, and has a certain degree of mobility and passability.

[0023] At the same time, a lifting arm mechanism 200 is installed on the vehicle body 100, and the lifting arm mechanism 200 can perform lifting movements in the vertical direction. Exemplarily, its lifting drive method can adopt various forms such as hydraulic cylinders, electric lead screws, or gears 413 and racks. On the premise of ensuring the structural strength, the monitoring equipment has a certain degree of height adjustability, which is beneficial to realizing the observation of tunnel cross-sections at different heights.

[0024] Furthermore, a telescopic arm mechanism 300 is provided at the top of the lifting arm mechanism 200, and the telescopic arm mechanism 300 can be telescoped in the horizontal direction. The setting of the telescopic arm mechanism 300 is beneficial to realizing long-distance horizontal extension in a long and space-limited tunnel, and improves the layout flexibility of the observation equipment without approaching the construction surface. The telescopic arm mechanism 300 is particularly suitable for high-section tunnels, and to a certain extent reduces problems such as picture distortion and monitoring dead angles caused by a long observation distance and a fixed angle.

[0025] Furthermore, a rotating mechanism 400 is provided between the lifting arm mechanism 200 and the telescopic arm mechanism 300. The rotating mechanism 400 can enable the telescopic arm mechanism 300 to rotate within a certain range on the horizontal plane, endowing the monitoring device with the ability to adjust horizontally at multiple angles. This rotating mechanism 400 allows the operator to flexibly adjust the monitoring perspective according to the on-site situation, improving the capture accuracy and integrity of the construction images, and further enabling project managers to grasp the construction dynamics from multiple angles and directions.

[0026] Finally, the monitoring mechanism 500 is installed at the distal end of the telescopic arm mechanism 300, including but not limited to various types of sensing or imaging devices such as high-definition camera devices, infrared imaging devices, laser scanners, dust concentration sensors, etc., which can be modularly selected or combined according to the specific requirements of the construction scene. The installation method of the monitoring mechanism 500 can be a gimbal adjustment type cloud platform structure, which is convenient for fine adjustment of the shooting angle and improves the observation clarity and accuracy of key parts. By placing the monitoring mechanism 500 at the end of the liftable, telescopic, and rotatable robotic arm, it has good accessibility and adaptability, and to a certain extent reduces problems such as poor image stability and limited monitoring range caused by traditional devices being stationary or swaying with the construction boom.

[0027] In addition, a data acquisition and wired transmission module can also be integrated inside the monitoring vehicle to collect and transmit in real time multi-source information such as the images collected by this vehicle and the operation data fed back by other on-site construction equipment to the project center, which helps to achieve the integrated management and visual analysis of construction data and improve the decision-making efficiency. Through the above structural design in this embodiment, while ensuring the observation stability and monitoring flexibility, it further takes into account the data aggregation and transmission requirements at the construction site, and has good adaptability and practicality.

[0028] In some embodiments, in combination with Figure 1 、 Figure 2 , the vehicle body 100 includes a vehicle frame 110 and a cabin 120 provided thereon. The vehicle frame 110 is the load-bearing basic structure of the whole vehicle, usually made of high-strength steel or alloy materials to provide the necessary structural strength and torsional stiffness, so as to have better seismic resistance and service life in complex construction environments such as tunnels. A plurality of tires 111 are provided at the lower end of the vehicle frame 110 for supporting the whole vehicle and realizing the moving function. Exemplarily, the number of tires 111 can be selected according to the size and load capacity of the vehicle body 100. Common configurations are four-wheel or six-wheel arrangements. The type of tires 111 can be pneumatic tires 111, solid rubber tires 111 or off-road tires 111 specially used for engineering vehicles to adapt to complex road conditions such as wet, uneven, and gravel-covered tunnel floors, which is conducive to the stable operation of the vehicle in the tunnel.

[0029] Exemplarily, the cabin 120 is disposed above the vehicle frame 110. As the core functional module accommodation unit of the vehicle, its internal space can be used to arrange the lifting arm mechanism 200, the electronic control unit of the monitoring equipment, the data processing module, the power supply system, etc. The cabin 120 adopts a closed structure, which helps to protect the internal equipment from dust, moisture and collision, and improves the stability and service life of the equipment. Exemplarily, the top wall of the cabin 120 is provided with an extension opening 121. The position and size of the extension opening 121 are designed according to the structural parameters of the lifting arm mechanism 200, and an elastic sealing ring or a protective cover plate can be set to form a basically closed state for the cabin when the lifting arm mechanism 200 is not raised, which is beneficial to reducing the influence of dust entry or external impact on the equipment.

[0030] On this basis, the lifting arm mechanism 200 is disposed inside the cabin 120. Its bottom is fixed on the installation base inside the cabin, and it can extend vertically through the extension opening 121. This structural arrangement is beneficial to the lifting arm mechanism 200 being accommodated inside the cabin in the non-working state, thereby reducing the overall vehicle height and improving the vehicle passability; in the working state, it can be quickly deployed outside the cabin 120 to cooperate with the telescopic arm and the monitoring device for operation. This structural design takes into account the compactness during vehicle transportation and the functionality during on-site operation to a certain extent, and has good practicability and integration. For the term "cabin 120", it should be understood as a cabin unit with an independent structure and a closed shell, which not only plays a structural support role, but also facilitates the modular layout and maintenance of equipment.

[0031] In some embodiments, such as Figure 1 、 Figure 2 and Figure 3 as shown, the lifting arm mechanism 200 includes a driving component 210 and a vertical telescopic component 220. Among them, the vertical telescopic component 220 can telescopically move in the vertical direction, and the driving component 210 is used to drive the vertical telescopic component 220 to telescopically move in the vertical direction.

[0032] Exemplarily, the driving component 210 includes an electric push rod 211.

[0033] Exemplarily, the vertical telescopic component 220 includes a base 221, a first cylinder 222, a second cylinder 223 and a third cylinder 224. Among them, the base 221 is installed on the inner bottom wall of the cabin 120; the first cylinder 222 is installed on the base 221, and the inside of the first cylinder 222 is hollow and the upper end is open; the second cylinder 223 is vertically slidably inserted into the first cylinder 222, and the inside of the second cylinder 223 is hollow and the upper end is open; the third cylinder 224 is vertically slidably inserted into the second cylinder 223; the electric push rod 211 is disposed on the base 221, the piston rod of the electric push rod 211 extends vertically, and the top of the piston rod of the electric push rod 211 is connected to the top of the first cylinder 222.

[0034] On this basis, the structure of the lifting arm mechanism 200 adopts a multi-section sleeve design, specifically including a driving component 210 and a vertical telescopic component 220. Among them, the driving component 210 is an electric push rod 211, which is arranged on the mounting base 221 at the bottom inside the shelter 120, and the piston rod is vertically upward, used to provide vertical thrust. The electric push rod 211 can select the structure of a linear electric push rod 211, and realizes the lifting control by the way of driving the lead screw by a motor. Compared with the hydraulic drive system, it has the advantages of compact structure, fast control response, and simple maintenance. To a certain extent, it is beneficial to improve the stability and accuracy of the telescopic component operation, and is especially suitable for the tunnel construction scenario with high requirements for environmental cleanliness.

[0035] At the same time, the vertical telescopic component 220 includes a base 221, a first cylinder 222, a second cylinder 223 and a third cylinder 224, forming a three-section sleeve-type coaxial sliding structure. Each cylinder is a hollow structure, sleeved along the vertical direction, and the upper end is open, which is beneficial to form a good sliding fit relationship during the telescopic process. The base 221 is firmly installed on the inner bottom wall of the shelter 120, providing a basic support for the telescopic system. The first cylinder 222 is arranged on the base 221 and is connected to the piston rod of the electric push rod 211, and is driven to move upward in the vertical direction by the upward movement of the piston rod. As the first cylinder 222 moves upward, its upper end gradually drives the second cylinder 223 inserted therein to extend out along the coaxial direction, forming an axial extension. When the first cylinder 222 reaches the predetermined stroke limit relative to the second cylinder 223, the second cylinder 223 begins to push the third cylinder 224 upward, so as to realize the sequential progressive vertical extension of the multi-stage cylinders. Through this kind of structure setting, a relatively large overall lifting stroke can be obtained under the condition of a relatively compact storage length, which is beneficial to arranging the monitoring device to a higher position, so as to realize a more comprehensive coverage monitoring of the tunnel section.

[0036] The sliding fit part of the above structure can be provided with a guide groove or a slide rail structure, and supplemented with a wear-resistant bushing or a low-friction coating material, which is beneficial to improving the sliding smoothness and durability between the cylinders. A limit mechanism can be set between each cylinder to limit the maximum extension length and avoid excessive stretching caused by misoperation. In addition, since the driving mechanism is arranged on the base 221, the vertical movement of the electric push rod 211 only drives the first cylinder 222, and the subsequent expansion of the cylinder is completed by mechanical sliding and self-weight or elastic element assistance. Therefore, the overall structure is more stable during operation, which is beneficial to improving the picture stability during the image acquisition of the monitoring equipment.

[0037] It should be noted that although the "first cylinder 222", "second cylinder 223", and "third cylinder 224" are distinguished by numbers, in specific implementations, they can also be sleeve structures of any quantity. Their naming is only used to describe the sequential relationship and does not limit the number of sleeve levels in specific implementations. In addition, the "electric push rod 211" can be a traditional lead screw type push rod, or a servo electric cylinder or an intelligent electric push device integrated with position feedback can be selected according to needs to further improve the control accuracy and remote control ability. This kind of structural design takes into account the structural compactness, maintainability, and high-position observation requirements to a certain extent, and has strong engineering adaptability and practical application value.

[0038] In some embodiments, such as Figure 3 , Figure 4 and Figure 5 shown, the rotating mechanism 400 includes a rotation drive assembly 410 and a rotating assembly 420. Among them, the rotating assembly 420 includes an upper turntable 421, a lower support column 422, a rotating column 423, and a rolling bearing 424. The lifting arm mechanism 200 is connected to the lower support column 422, and the telescopic arm mechanism 300 is connected to the upper turntable 421; further, the rotating column 423 is coaxially arranged below the upper turntable 421, a rotating groove is opened at the center of the upper surface of the lower support column 422, and the rolling bearing 424 is press-fitted in the rotating groove. The rotating column 423 is inserted into the inner ring of the rolling bearing 424 and is press-fitted with the rolling bearing 424; further, the rotation drive assembly 410 is arranged on the outer peripheral wall of the lower support column 422, and the rotation drive assembly 410 is used to drive the upper turntable 421 to rotate relative to the lower support column 422.

[0039] Exemplarily, the rotation drive assembly 410 includes a drive box 411, a rotation motor 412, and a gear 413. The drive box 411 is fixedly installed on the outer peripheral wall of the lower support column 422, the rotation motor 412 is arranged in the drive box 411, and the gear 413 is coaxially arranged on the output shaft of the rotation motor 412; a gear ring 4211 is arranged on the outer periphery of the upper turntable 421, a drive hole is opened on the side wall of the drive box 411, and a part of the gear 413 extends out of the drive hole and meshes with the gear ring 4211.

[0040] On this basis, when the rotation motor 412 is started, the output shaft of the rotation motor 412 will drive the gear 413 to rotate at this time. Since the gear 413 meshes with the gear ring 4211, the gear 413 will drive the gear ring 4211 to rotate, and then the upper turntable 421 rotates relative to the lower support column 422, so that the entire telescopic arm mechanism 300 can change its position by 0° - 360° in the horizontal direction, improving the adjustment range of the telescopic arm mechanism 300.

[0041] In some embodiments, in combination with Figure 1 , Figure 2 and Figure 3, the telescopic arm mechanism 300 includes a top seat 310, a first multi-stage cylinder 320, and a second multi-stage cylinder 330. The top seat 310 is installed at the top of the rotating mechanism 400 and is used as the installation reference plane for the two multi-stage cylinders. Further, the first multi-stage cylinder 320 extends horizontally and is disposed on one side of the top seat 310, and the second multi-stage cylinder 330 extends horizontally in a direction away from the first multi-stage cylinder 320 and is disposed on the other side of the top seat 310, and the first multi-stage cylinder 320 and the second multi-stage cylinder 330 are coaxially arranged; further, the maximum extended length of the first multi-stage cylinder 320 is less than the maximum extended length of the second multi-stage cylinder 330.

[0042] Exemplarily, the monitoring mechanism 500 includes a first camera 510, a second camera 520, and a lighting member 530. The first camera 510 is disposed at the end of the piston rod of the first multi-stage cylinder 320, and the second camera 520 and the lighting member 530 are both disposed at the end of the piston rod of the second multi-stage cylinder 330.

[0043] After such a setting, both the first multi-stage cylinder 320 and the second multi-stage cylinder 330 extend in the horizontal direction and are axially symmetrically arranged on the top seat 310, that is, they have a common central axis direction, making the structures on both sides more balanced in spatial distribution, which helps to maintain the overall center of gravity stability of the system during the operation of the telescopic arm and improve the balance performance and action fluency when the rotating mechanism 400 rotates. The maximum extended length of the first multi-stage cylinder 320 is less than that of the second multi-stage cylinder 330, forming an asymmetric extension structure layout. The first multi-stage cylinder 320 is disposed on the side close to the vehicle body 100, and a first camera 510 is installed at the end of its piston rod for observing the near-field area of the tunnel. Since this part is close to the vehicle body 100, sufficient lighting conditions can usually be obtained by means of the lighting device provided on the vehicle itself, so additional lighting equipment may not be provided, thereby simplifying the device structure to a certain extent, reducing the manufacturing cost, and saving the vehicle-mounted power load.

[0044] Relatively, the maximum extended length of the second multi-stage cylinder 330 is longer, and a second camera 520 and a lighting member 530 are installed at the end of its piston rod, which can penetrate into a farther area for image acquisition. In a complex tunnel environment, the illuminance in the area far from the vehicle body 100 is usually low. Setting a dedicated lighting member 530 is beneficial to ensuring the imaging quality of the second camera 520 in a low-light environment and improving the clarity and usability of video or image data. The lighting member 530 can be selected as a high-brightness LED module and is provided with a dust-proof and waterproof housing to adapt to the use conditions such as high dust and high humidity at the construction site.

[0045] Through such a structural layout with one long and one short and functionally differentiated components, the system can deploy monitoring units with different functions within different distance ranges, which is beneficial to expanding the data acquisition coverage and flexibly adjusting the acquisition angle and content according to requirements. For example, the first camera 510 is suitable for observing the operating state of construction equipment or the surrounding environment of the vehicle body 100, while the second camera 520 is suitable for long-distance detection of the structural details in front of or on the top of the tunnel. This arrangement not only improves the information acquisition ability of the monitoring system but also saves the system construction cost and wiring complexity to a certain extent.

[0046] It should be noted that the "multi-stage cylinder" should be understood here as a cylinder device with a piston rod adopting a multi-section sleeve structure, which realizes multi-section sequential propulsion through pneumatic drive, so as to obtain a larger extension stroke while keeping the contraction length compact. This type of structure is commonly used in engineering equipment with limited space but large stroke requirements, and has good space utilization rate and action response speed, and is suitable for the complex tunnel operation environment involved in the present invention.

[0047] In some embodiments, in combination with Figure 3 , Figure 4 and Figure 5 , a shielding portion 4111 is provided on the outer periphery of the driving hole on the driving box 411, and an engaging space 4112 for the engaging portion of the shielding gear ring 4211 and the gear 413 is formed within the shielding portion 4111, and the engaging space 4112 is communicated with the driving hole. Further, a dust-blowing and temperature-reducing mechanism 600 is provided on the driving box 411. The dust-blowing and temperature-reducing mechanism 600 is used to blow out the dust in the engaging tooth gap of the gear ring 4211 when the engaging teeth of the gear ring 4211 enter the engaging space 4112, and at the same time take away the heat in the driving box 411.

[0048] Exemplarily, the dust-blowing and temperature-reducing mechanism 600 includes a blowing component 610 and a drainage component 620. Among them, the blowing component 610 includes a blower 611, a blowing hose 612 and a blowing hard pipe 613. The blower 611 is installed on the outer wall of the driving box 411. Two blowing hoses 612 are provided and are both communicated with the blowing end of the blower 611. The blowing hard pipe 613 is installed on the top edge of the driving box 411. The top end of the blowing hard pipe 613 is communicated with the blowing hose 612, and the bottom end is vertically downward. Before the engaging teeth of the gear ring 4211 enter the engaging space 4112, the blowing hard pipe 613 blows cold air into the engaging tooth gap of the gear ring 4211 to blow away the dust in the engaging tooth gap of the gear ring 4211 from top to bottom.

[0049] Exemplarily, the drainage component 620 includes a vertical drainage pipe 621, an arc-shaped drainage pipe 622, and branch pipes 623. The arc-shaped drainage pipe 622 is disposed inside the drive box 411. One end of the arc-shaped drainage pipe 622 is located on the first outer side of the drive box 411 and the arc is upward. The other end of the arc-shaped drainage pipe 622 is located on the second outer side of the drive box 411 and horizontally faces away from one end of the drive box 411. The vertical drainage pipe 621 is communicatively provided at one end of the arc-shaped drainage pipe 622 and is vertically aligned with the blast hard pipe 613. A plurality of branch pipes 623 are communicatively provided on the pipe section of the arc-shaped drainage pipe 622 located inside the drive box 411, and each branch pipe 623 inclines toward the side close to the vertical drainage pipe 621, so that dust is not easily removed from the branch pipe 623 when flowing in the arc-shaped drainage pipe 622 following the fluid.

[0050] Since there is dust in the tunnel and the gear ring 4211 is exposed outside the upper turntable 421, the floating dust can easily enter the meshing tooth gaps of the gear ring 4211. When the gear ring 4211 with dust meshes with the gear 413, the wear between the gear ring 4211 and the gear 413 will increase, reducing the service life. Therefore, after forming the meshing space 4112 outside the drive box 411 through the shielding portion 4111, before the gear ring 4211 enters the meshing space 4112, the blower 611 is started, so that the wind power of the blower 611 enters the blast hard pipe 613 through the blast hose 612 and finally blows out from the blast hard pipe 613. The meshing tooth gaps of the rotating gear ring 4211 will pass through the wind power part blown out from the blast hard pipe 613. Under the action of the wind power, most of the dust remaining in the meshing tooth gaps of the gear ring 4211 will be blown away and enter the vertical drainage pipe 621 following the flowing direction of the wind power, and is discharged in the direction away from the gear ring 4211 through the arc-shaped drainage pipe 622. In this way, the excess dust can be blown away without being scattered around the gear ring 4211, reducing the possibility that the blown-away dust adheres to the meshing tooth gaps of the gear ring 4211 again. At the same time, when the fluid with dust passes through the arc-shaped drainage pipe 622, due to the existence of the branch pipes 623, the heat inside the drive box 411 can enter the arc-shaped pipe through the branch pipes 623, and then is discharged from the drive box 411 following the fluid with dust, improving the heat dissipation effect inside the drive box 411. Moreover, since the branch pipes 623 all incline toward the side close to the vertical drainage pipe 621, dust is not easily moved from the branch pipes 623 to the inside of the drive box 411 when flowing in the arc-shaped drainage pipe 622 following the fluid. In this way, the dust in the meshing tooth gaps of the gear ring 4211 can be effectively removed, and the heat inside the drive box 411 can be reduced incidentally, improving the heat dissipation effect.
