DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0038] It should be noted that in the appendix of the manual Figure 1 In the present disclosure, the directions or positional relationships indicated by terms such as "upper," "lower," "front," "back," "left," and "right" are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this application and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] like Figures 1 to 4 As shown, in this embodiment, a straddle-type monorail engineering vehicle is provided. The engineering vehicle is slidably arranged on the track beam 1. It includes a vehicle body and an aerial work platform 8 and a descending work platform 9 arranged on the vehicle body. The aerial work platform 8 is a scissor-type structure. Its elevation adopts the telescopic method of a vertical hydraulic cylinder, and its horizontal extension adopts the telescopic method of a horizontal hydraulic cylinder. Figure 2As shown, the high-altitude operation platform 8 is stretched to facilitate personnel maintenance, and the vertical lifting stroke and the horizontal pushing stroke can be adjusted according to actual equipment maintenance. Of course, the stroke needs to meet the requirements of the detection signal machine and the lightning rod located above the track beam 1. The telescopic mode of the descending operation platform 9 is the vertical hydraulic cylinder, and the horizontal pushing mode is the inclined hydraulic cylinder, which drives the side wall of the descending operation platform 9 to flip. Of course, the vertical descending stroke and the horizontal pushing stroke of the descending operation platform 9 can be adjusted according to the requirements of actual equipment maintenance, and the stroke needs to meet the requirements of the lightning box located below the track beam 1. Here, it will not be described in detail.

[0040] In addition, the above-mentioned engineering vehicle also includes two sets of vehicle body posture correction devices 10, which are fixedly arranged below the vehicle body 2 and located at the front half and rear half of the vehicle body 2 respectively, so as to ensure that the front and rear parts of the vehicle body 2 can be adjusted. Any one of the vehicle body posture correction devices 10 includes two vertical cylinders 101, two inclined cylinders 102 and two side supports 103. Any one of the vertical cylinders 101 is located between the vehicle body 2 and the track beam 1 and is fixed on the vehicle body 2, with the power end facing the end surface of the track beam 1. Any one of the inclined cylinders 102 is hinged to the vehicle body 2, with the power end facing the side wall of the track beam 1. It should be noted that the two vertical cylinders 101 are symmetric about the center line of the track beam 1, and the two inclined cylinders 102 are also symmetric about the center line of the track beam 1.

[0041] As for the above-mentioned side supports 103, each side support 103 is used to connect the power end of the vertical cylinder 101 and the power end of the inclined cylinder 102 located on the same side of the center line of the track beam 1, and the side support 103 is arranged in an L shape. The power end of the vertical cylinder 101 and the power end of the inclined cylinder 102 correspond to the two end surfaces of the L-shaped structure respectively. The end surface of any one of the side supports 103 away from the vertical cylinder 101 abuts against the upper end surface of the track beam 1, and the end surface away from the inclined cylinder 102 abuts against the side wall of the track beam 1. That is to say, the inner end surface of the side support 103 needs to abut against the right-angled corner of the track beam 1 to prevent the side support 103 from loosening.

[0042] In summary, the engineering vehicle adjusts the posture of the engineering vehicle through the vehicle body posture correction devices 10 arranged below the vehicle body 2. Specifically, the number of the vehicle body posture correction devices 10 is two sets, which are located at the front half and rear half of the vehicle body 2 respectively. Any one of the vehicle body posture correction devices 10 includes two vertical cylinders 101, two inclined cylinders 102 and two side supports 103. The power end of the two vertical cylinders 101 drives the two side supports 103 to be fixed on the track beam 1, and the longitudinal posture of the vehicle body 2 is adjusted by adjusting the four vertical cylinders 101 in the two sets of vehicle body posture correction devices 10. The transverse posture of the vehicle body 2 is adjusted by adjusting the four inclined cylinders 102 in the two sets of vehicle body posture correction devices 10.

[0043] In addition, the two side supports 103 are arranged in an L shape, can bear the eccentric load moment generated when the crane 6 is working, and ensure that the vehicle body 2 can complete the lifting work of the crane 6 after the attitude is adjusted. Further, the two vertical oil cylinders 101 in any one set of vehicle body attitude correction device 10 are symmetrically arranged about the center line of the rail beam 1, the two inclined oil cylinders 102 are symmetrically arranged about the center line of the rail beam 1, and the vertical oil cylinder 101 and the inclined oil cylinder 102 located on the same side correspond to the two end faces of the L-shaped structure respectively, so as to ensure the stability of the force borne by the vertical oil cylinder 101 and the inclined oil cylinder 102.

[0044] Of course, the longitudinal and transverse attitudes of the vehicle body 2 can be adjusted by the two sets of vehicle body attitude correction devices 10. As for adjusting which vertical oil cylinder 101 and / or inclined oil cylinder 102 in the two sets of vehicle body attitude correction devices 10, it can be selected according to actual needs, or multiple vertical oil cylinders 101 and / or inclined oil cylinders 102 can be adjusted at the same time, and the purpose is to adjust the attitude of the vehicle body 2. That is to say, when the attitude of the vehicle body 2 is horizontal, the aerial work platform 8 and the descending work platform 9 arranged on the vehicle body 2 are also in a horizontal state. Therefore, the engineering vehicle arranged in the above manner can correct the attitude of the vehicle body 2 in the curved inclined line interval and the large-angle uphill and downhill interval, and there is no safety hazard when personnel are overhauled through the aerial work platform 8 and the descending work platform 9 or when heavy objects are hung, avoiding the embarrassment that the line overhaul and equipment replacement in this interval need to be carried out from the ground.

[0045] In addition, during normal driving of the engineering vehicle, the side support 103 needs to be arranged at intervals with the rail beam 1. When the vehicle is stopped in the curved inclined line interval and the large-angle uphill and downhill interval, the vertical oil cylinder 101 controls the side support 103 to abut against the rail beam 1, and after the two are stably arranged, the longitudinal attitude of the vehicle body 2 is corrected to be horizontal by adjusting the extension and retraction of one or more vertical oil cylinders 101; the transverse attitude of the vehicle body 2 is corrected to be horizontal by adjusting the extension and retraction of one or more inclined oil cylinders 102.

[0046] It should be noted that the above-mentioned straddle-type monorail engineering vehicle also includes a connector 3, as shown in Figure 5 and Figure 6 The connector 3 is located at the end of the vehicle body 2 in the direction of travel, the connector 3 includes a rear frame 31 fixed to the end of the vehicle body 2 in the direction of travel, the end of the rear frame 31 away from the vehicle body 2 is provided with a front frame 32, and the front frame 32 is provided with a hook 33. Among them, two different vehicle bodies 2 are provided with a connector 3, the connectors 3 located on the two different vehicle bodies 2 are used to connect the two vehicle bodies 2, and the two front frames 32 abut against each other and the two hooks 33 are hung with each other, so that the two different connectors 3 on the two different vehicle bodies 2 are stably connected.

[0047] In addition, the connector 3 further comprises a lower frame 34, an air spring 35, a damper 36 and a buffer pad 37. The lower frame 34 is fixed to the vehicle body 2 and corresponds to the position of the front frame 32. The air spring 35 is used to connect the lower frame 34 and the front frame 32, and supports the front frame 32 to bear the load. The damper 36 is located between the front frame 32 and the rear frame 31, and can eliminate the impact of the collision when the two different vehicle bodies 2 are connected. The buffer pad 37 is located at the end of the front frame 32 away from the damper 36, and can reduce the force between the two connected connectors 3.

[0048] It should be noted that, as shown in Figure 6 When the two vehicle bodies 2 are connected by the connector 3, the running plate can be arranged on the two connectors 3 to provide a space for personnel circulation and cargo transportation. At the same time, personnel can directly reach the working platform 21 on the vehicle body 2. The periphery of the working platform 21 is provided with a fence 4. In order to facilitate personnel circulation, the fence 4 at the end of the vehicle body 2 in the running direction is detachable. Of course, the fence 4 here can also be in other forms of arrangement, as long as personnel can walk between the two different vehicle bodies 2.

[0049] In addition, for the two connected vehicle bodies 2, the buffer pad 37 can ensure the damping and wear-resistant effect when the two vehicle bodies 2 are connected, and reduce the friction loss generated by the connector 3 when turning. The telescopic damper 36 can ensure that the two vehicle bodies 2 smoothly pass through the curve interval. The cover plate above the connector 3 is still passable for personnel and cargo transportation.

[0050] Of course, the above engineering vehicle further comprises a power system 5, which can provide the required power for the whole vehicle, such as power for the vertical oil cylinder 101, the tilting oil cylinder 102, the aerial work platform 8, the descending work platform 9, the bogie 7, etc. The above components are not limited to the above-mentioned components, and the specific arrangement mode is not described here. Please refer to the prior art for details.

[0051] It should be noted that, in the present specification, the relationship terms such as first and second are only used to distinguish one entity from another entity, and do not necessarily require or imply any such actual relationship or order between the entities.

[0052] The principles and implementation modes of the present application are described by using specific examples in the present text. The above description of the examples is only used to help understand the method of the present application and its core idea. It should be noted that, for ordinary skilled persons in the technical field, some improvements and modifications can be made to the present application without departing from the principles of the present application.
