[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] like Figure 1 to Figure 2 As shown, the all-terrain upright rocket carrier of the present invention includes a steel structure body 1, a fixing device 2, a traveling mechanism 3, a steering mechanism 4 and a hydraulic system 5, wherein: the rocket fixing device 2 is arranged in the middle of the steel structure body 1, and is used for fixing the rocket; the traveling mechanism 3 is arranged at the bottom of the steel structure body 1, and is used for providing support and movement to the steel structure body 1; the steering mechanism 4 is arranged between the traveling mechanism 3 and the steel structure body 1, and is used for driving the traveling mechanism 3 to rotate; the hydraulic system 5 is respectively connected to the traveling mechanism 3 and the steering mechanism 4, and is used for providing power to the traveling mechanism 3 and the steering mechanism 4.

[0024] Furthermore, in the above-mentioned all-terrain upright rocket carrier, the steel structure body 1 includes a body floor 11, a railing 12 and an access ladder 13. The body floor 11 is rectangular or circular, the railing 12 is fixed along the outer edge of the body floor 11, the access ladder 13 is arranged on one side of the body floor 11, and the fixing device 2 is installed at the upper end of the body floor 11, so as to facilitate the staff to go up and down the platform and ensure the safety of the staff.

[0025] Furthermore, in the above-mentioned all-terrain upright rocket carrier, the walking mechanism 3 includes a support arm 31, a brake arm 32, a first hydraulic cylinder 33, a hydraulic motor 34 and a wheel 35. The brake arm 32 is rotatably arranged on one side of the support arm 31, the mounting end of the first hydraulic cylinder 33 is hinged to the support arm 31, the output end of the first hydraulic cylinder 33 is hinged to the brake arm 32, the hydraulic motor 34 is installed on the support arm 31, and the wheel 35 is installed at the output end of the hydraulic motor 34, so that walking is achieved by controlling the hydraulic motor 34 to drive the wheel 35 to rotate, and the wheel 35 is braked by controlling the first hydraulic cylinder 33 to drive the brake arm 32.

[0026] Furthermore, in the above-mentioned all-terrain upright rocket carrier, the steering mechanism 4 includes a slewing bearing 41, a traction device 42 and a second hydraulic cylinder 45. The inner ring of the slewing bearing 41 is fixed to the lower end of the vehicle body bottom plate 11 by bolts, and the outer ring of the slewing bearing 41 is fixed to the top of the support arm 31 by bolts. The traction device 42 is installed on one side of the vehicle body bottom plate 11, and the mounting end of the second hydraulic cylinder 45 is fixed on one side of the vehicle body bottom plate 11. The output end of the second hydraulic cylinder 45 is connected to the slewing bearing 41 through the traction device 42. The support arm 31 can be rotated 360 degrees on the vehicle body bottom plate 11 through the slewing bearing 41. At the same time, the rotation angle of the support arm 31 is controlled by the cooperation of the second hydraulic cylinder 45 and the traction device 42, so as to effectively realize various walking modes such as straight movement, straight rotation, oblique movement, horizontal movement, center rotation, head swing, tail swing and horizontal rotation on the vehicle body bottom plate 11.

[0027] Furthermore, in the above-mentioned all-terrain upright rocket carrier, a steering traction ring 46 is welded to one side of the upper end of the outer ring of the slewing bearing 41, one end of the traction device 42 is connected and fixed to the steering traction ring 46, and the other end is fixed to the output end of the second hydraulic cylinder 45;

[0028] Preferably, the traction device 42 may be a connecting rod mechanism, one end of which is connected and fixed to the steering traction ring 46 , and the other end of which is fixed to the output end of the second hydraulic cylinder 45 .

[0029] Further, in the above-mentioned all-terrain upright rocket carrier, the hydraulic system 5 is connected to the first hydraulic cylinder 33, the second hydraulic cylinder 45 and the hydraulic motor 34 respectively;

[0030] Preferably, Figure 3As shown, the hydraulic system 5 may include a hydraulic station 51, a proportional valve 52 and an electromagnetic reversing valve 53. The hydraulic station 51 has N+1 output ends, wherein N is the number of the second hydraulic cylinders 45. The N output ends of the hydraulic station 51 are respectively connected to the oil circuits of the second hydraulic cylinders 45 through the proportional valves 52, thereby effectively ensuring that the second hydraulic cylinders 45 can be extended and retracted at a certain speed at the same time, and can also be extended and retracted independently, so that the walking mechanism 3 can achieve a variety of walking modes according to the control direction. Another output end of the hydraulic station 51 is connected to the input end of the electromagnetic reversing valve 53. The left side of the electromagnetic reversing valve 53 is connected to the oil circuit of the first hydraulic cylinder 33, and the right side of the electromagnetic reversing valve 53 is connected to the oil circuit of the hydraulic motor 34, so that the hydraulic motor 34 does not work when the brake arm 32 brakes, and the brake arm 32 is always in a braking state when the walking mechanism 3 stops walking, effectively ensuring parking safety.

[0031] Specifically, the rocket is fixed on the vehicle body bottom plate 11 by the fixing device 2. During transportation, the hydraulic station 51 outputs hydraulic oil to drive the hydraulic motor 34 on the support arm 31 to rotate through the right side position of the electromagnetic reversing valve 53, so that the wheel 35 rotates to realize walking. When the direction of rotation is required, the N output ports of the output end of the hydraulic station 51 simultaneously output hydraulic oil, and the second hydraulic cylinder 45 is extended or recovered at a certain speed through the proportional valve 52. At this time, the traction rope 44 drives the slewing bearing 41 to rotate through the steering traction ring to achieve the steering purpose. When other action adjustments are made, such as swing adjustment, half of the hydraulic cylinder can be extended and the other half can be recovered for operation by controlling the N output ends, thereby realizing a variety of walking modes such as straight travel, straight rotation, oblique travel, horizontal travel, center rotation, head swing, tail swing and horizontal rotation. When stopping during transportation or reaching the transportation end, the hydraulic oil of the hydraulic motor 34 can be interrupted by the electromagnetic reversing valve 53, and the first hydraulic cylinder 33 can be switched to the left side to drive it to extend and push the brake arm 32 to brake the wheel 35.

[0032] In summary, compared with the prior art, the all-terrain upright rocket carrier of the present invention has the following advantages and beneficial effects: the overall structure of the present invention is simple, and the cooperation of the walking mechanism and the steering mechanism can meet the requirements of all-terrain walking. It is suitable for multiple assembly plants corresponding to one launch tower, and there is no need to build dedicated tracks, which effectively reduces operation and construction costs and improves environmental adaptability.
