Description

Technical Field

[0001] This utility model belongs to the field of urban aerial rail transit technology, and in particular, it is a manned inspection vehicle for the operation status of facilities inside the aerial rail track beam. Background Technology

[0002] With the rapid development of cities and the continuous influx of population in my country, the number of private cars has also increased accordingly, exacerbating urban traffic congestion. Due to its unique underground operation and high construction costs, the development of underground rail transit has gradually entered a period of slowdown. During this period, our company introduced advanced monorail technology from Germany.

[0003] Skyrail combines the advantages of subways without requiring the massive investment of subways. It is currently a pioneering innovation in China, and everything is still in the exploratory stage.

[0004] Because this type of foreign monorail track beam has internal power supply rails and turnouts, loosening and displacement of connecting components such as fixing bolts are inevitable during use. To ensure safe operation, daily safety inspections of the track beam's operating status are essential. Furthermore, the track beam's unique structure means that half of the drive wheel is suspended in the air when passing through turnout areas. For this situation, foreign companies use externally suspended inspection vehicles, with the vehicle body outside the track beam and the inspection vehicle's rollers on the internal track. Personnel must enter from the bottom of the track beam, which is very inconvenient. Moreover, purchasing inspection vehicle technology compatible with foreign monorail technology is also an expense. Utility Model Content

[0005] The purpose of this invention is to address the inconvenience of using inspection vehicles and the cost of purchasing supporting inspection vehicle technology in this type of new air rail technology abroad, and to propose a manned inspection vehicle for the operation status of facilities inside the air rail track beam.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a manned inspection vehicle for monitoring the operation status of facilities inside air-rail track beams, including a chassis and a frame, with the frame fixed to the chassis.

[0008] The chassis has a seat at the front and rear ends, two pairs of driving wheels at the bottom, and two chassis guide wheels on the left and right sides.

[0009] The chassis is also equipped with a dual-shaft motor, and the output shaft of one end of the dual-shaft motor drives a pair of driving wheels to rotate through a reducer;

[0010] The vehicle is equipped with two guide wheels on the left and right sides, respectively.

[0011] The total width of the underframe and the guide wheels of the left and right underframes is the same as the inner width of the track beam, and the total width of the upper frame and the guide wheels of the left and right upper frames is the same as the inner width of the track beam.

[0012] In the dual-track road surface state in the track beam, the left front and rear two moving wheels correspond to the left single rail, the right front and rear two moving wheels correspond to the right single rail, and the left and right side base frame guide wheels and upper frame guide wheels respectively contact the side wall of the track beam.

[0013] In the monorail track condition within the track beam, the front and rear driving wheels on one side correspond to the monorail, while the left and right underframe guide wheels and upper frame guide wheels respectively contact the turnout sidewalls within the track beam.

[0014] As a further preferred embodiment, a power switching device is provided on the other output shaft of the dual-shaft motor. The power switching device includes a fixed gear ring, a sliding sleeve, a drive pulley, and a bearing. The inner rings of the fixed gear ring and the bearing are respectively fixed on the other output shaft of the dual-shaft motor. The sliding sleeve is fixed on the outer ring of the bearing. The sliding sleeve is provided with a fixed drive pulley and a movable gear ring that moves along the axial direction of the sliding sleeve. The fixed gear ring and the movable gear ring can be engaged and disengaged.

[0015] The chassis is equipped with a lever and a rotating seat. The lever is rotatably connected to the rotating seat at its lower part. A shift fork is connected to the lower end of the lever. The shift fork is connected to the moving gear ring and controls the moving gear ring to move on the sliding sleeve and engage and disengage with the fixed gear ring.

[0016] The vehicle frame is equipped with a hand crank, and a timing belt is wound between the hand crank and the drive pulley.

[0017] As a further preferred option, the underframe is also equipped with a tensioner pulley that contacts the timing belt.

[0018] As a further preferred option, the hand crank faces the seat, and the frame of the vehicle is equipped with a hand crank shaft that limits rotation. The hand crank shaft is equipped with a hand crank pulley, and a synchronous belt is wound between the hand crank pulley and the drive pulley. There is a hand crank at each end of the hand crank shaft, and one hand crank corresponds to one seat.

[0019] As a further preferred option, a foot brake is also provided on the underframe, and a material box is also provided on the upper frame.

[0020] This invention can meet the need for the localization of new German monorail technology, so that the production and use of monorail supporting equipment no longer depends on foreign technology, saving a lot of money used to purchase foreign equipment; and solves the problem of difficulty in inspecting the internal facilities of the track beam in actual operation and maintenance, avoiding the need for manual drilling into the track beam for inspection, improving the efficiency of inspection work and reducing labor intensity.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] This utility model discloses a manned inspection vehicle for monitoring the operation of facilities inside an elevated railway track beam. Its working environment is inside the track beam, which has a rectangular cross-section, including the side walls and two tracks at the bottom. However, due to the limitations of imported elevated railway technology, the track beam, as the carrier supporting the elevated railway vehicle, contains internal structures such as power supply rails and reversing switches. Figure 9 As shown, in the branching section, there is only a single track for the inspection vehicle to travel on. In order to ensure the safe and normal operation of each internal mechanism, daily inspection work is required. This patent is a technical improvement for this working environment.

[0032] like Figure 1 As shown, the inspection vehicle of this utility model includes a chassis 1 and a chassis 2. The chassis 2 is fixed on the chassis 1 and forms the main structure of the inspection vehicle. The vertical width of the main structure is slightly smaller than the inner width of the track beam.

[0033] The chassis 1 has a seat 3 at the front and rear ends respectively. The bottom of the chassis 1 has two pairs of driving wheels 4. In the direction of travel of the inspection vehicle, the two on the left correspond to one track and the two on the right correspond to another track. The chassis 1 has two chassis guide wheels 5 on the left and right sides respectively. In the direction of travel of the inspection vehicle, the two on the left correspond to the inner left wall of the track beam and the two on the right correspond to the inner right wall of the track beam. The chassis guide wheels 5 play a role in driving stability.

[0034] like Figure 1 and 2 As shown, the chassis 1 is also equipped with a dual-shaft motor 6. One end of the output shaft of the dual-shaft motor 6 drives a pair of driving wheels 4 to rotate through a reducer 7. Correspondingly, the chassis 1 has a motor controller and a lithium iron phosphate battery to provide power and control for the dual-shaft motor 6.

[0035] The chassis 1 has a through slot at the dual-shaft motor 6 for controlling the dual-shaft motor 6.

[0036] The upper frame 2 is equipped with two upper frame guide wheels 8 on the left and right sides respectively. The upper frame guide wheels 8 play a stabilizing role when traveling under double rails and a lateral support role when traveling under single rails.

[0037] According to design requirements, the total width of the underframe 1 and the left and right side underframe guide wheels 5 is slightly smaller than the inner width of the track beam, and the total width of the upper frame 2 and the left and right side upper frame guide wheels 8 is slightly smaller than the inner width of the track beam; to ensure the stability of the inspection vehicle in both dual-rail and single-rail driving states.

[0038] That is, in the double-track road surface state in the track beam, the two front and rear moving wheels 4 on the left side correspond to the left single rail, and the two front and rear moving wheels 4 on the right side correspond to the right single rail. The left and right side base frame guide wheels 5 and upper frame guide wheels 8 are in contact with the side wall of the track beam respectively. At this time, the base frame guide wheels 5 and upper frame guide wheels 8 only play a stabilizing role.

[0039] In the monorail track condition, the two front and rear driving wheels 4 on one side correspond to the monorail. The left and right side base guide wheels 5 and upper frame guide wheels 8 maintain a small gap with the side wall of the track beam. Since the inspection vehicle tends to tip over when traveling on the monorail, there will be lateral pressure on the inner wall of the track beam. Since the vertical width of the main body structure of the inspection vehicle is slightly smaller than the inner width of the track beam, the upper frame guide wheels 8 mainly bear this lateral pressure, realize the lateral support force, and ensure rolling, so that the inspection vehicle will not derail or tip over in the track beam, and keep the inspection vehicle moving.

[0040] In summary, the inspection vehicle uses eight guide wheels supported on the side wall of the track beam and is driven by half of the drive wheel to pass through the turnout. The wheels rely on the support force of the bottom surface and the lateral support force of the side wall to form a stable mechanical balance relationship, thus enabling it to safely pass through the turnout area and realize daily inspections throughout the entire track beam.

[0041] On the other hand, considering the possibility of equipment failure preventing the inspection vehicle from returning to the maintenance base, the inspection vehicle is equipped with both automatic and manual driving functions. It is equipped with a manual drive mechanism, which connects the manual drive and electric drive through a clutch. They share a set of mechanical transmission structures but operate independently.

[0042] Specifically, such as Figure 3 and 4 As shown, a power switching device (clutch) is provided on the output shaft of the other end of the dual-shaft motor 6. The power switching device includes a fixed gear ring 9, a sliding sleeve 10, a drive pulley 11, and a bearing 12. The inner rings of the fixed gear ring 9 and the bearing 12 are respectively fixed on the output shaft of the other end of the dual-shaft motor 6. The sliding sleeve 10 is fixed on the outer ring of the bearing 12. The drive pulley 11 and the moving gear ring 13 that move along the axial direction of the sliding sleeve 10 are fixedly sleeved on the sliding sleeve 10. The fixed gear ring 9 and the moving gear ring 13 can mesh and separate.

[0043] When driven by the dual-axis motor 6, the fixed gear ring 9 and the moving gear ring 13 are separated, and the output shaft of the dual-axis motor 6 drives the fixed gear ring 9 and the inner ring of the bearing 12 to rotate freely; when manual driving is required, the fixed gear ring 9 and the moving gear ring 13 are engaged, and the rotation of the moving gear ring 13 drives the fixed gear ring 9 and the output shaft of the dual-axis motor 6 to rotate, thereby realizing the transmission of force and driving the moving wheel 4 to rotate.

[0044] The movable gear ring 13 is mounted on the sliding sleeve 10 via a type A key. The movable gear ring 13 can only move along the axial direction of the sliding sleeve 10. That is, the movable gear ring 13, type A key, sliding sleeve 10, and drive pulley 11 form a rotating unit and rotate together to achieve force transmission.

[0045] Matching, such as Figure 5 and 6 As shown, a shift fork mechanism is provided. A shift lever 14 is provided on the chassis 1, and a rotating seat 15 is provided on the chassis 1. The lower part of the shift lever 14 is rotatably connected to the rotating seat 15. The lower end of the shift lever 14 is rotatably connected to a shift fork 16. The shift fork 16 is connected to the moving gear ring 13, which controls the movement of the moving gear ring 13 on the sliding sleeve 10 to engage and disengage with the fixed gear ring 9. The moving gear ring 13 has an annular groove along the circumference of the sliding sleeve 10. The two ends of the shift fork 16 are in the annular groove through shift fork blocks, and the moving gear ring 13 can rotate relative to the shift fork blocks.

[0046] like Figure 1 and 7As shown, the vehicle frame 2 of this utility model is equipped with a hand crank 17, and a synchronous belt 18 is wound between the hand crank 17 and the drive pulley 11. The operator can manually rotate the hand crank 17, which drives the drive pulley 11 to rotate through the synchronous belt 18, thereby realizing the manual driving of the inspection vehicle; the vehicle chassis 1 is also equipped with a tensioning wheel, which contacts the synchronous belt 18 and is used to press the synchronous belt 18.

[0047] The chassis 1 is also equipped with a foot brake, and the upper frame 2 is also equipped with a material box 20.

[0048] Furthermore, such as Figure 8 As shown, the hand crank 17 faces the seat 3. The vehicle frame 2 is equipped with a hand crank shaft 19 that limits rotation. The hand crank shaft 19 is mounted on the vehicle frame 2 through bearings. The hand crank shaft 19 is equipped with a hand crank pulley. A synchronous belt 18 is wound between the hand crank pulley and the drive pulley 11. Each end of the hand crank shaft 19 is equipped with a hand crank 17. One hand crank 17 corresponds to one seat 3, which can enable two operators to jointly drive the inspection vehicle.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
