Description

Technical Field

[0001] This invention relates to an all-terrain adaptive tracked gas cylinder transport vehicle, belonging to the technical field of gas cylinder transport. Background Technology

[0002] Currently, in scenarios such as power system substations (e.g., 500kV substations), gas processing centers, and gas warehouses, the handling of gas cylinders (e.g., SF6 cylinders, oxygen cylinders) faces both inefficiency and safety hazards due to complex terrain and strict equipment layout. Existing technologies primarily rely on two methods for cylinder handling: one is to transport the cylinders to the vicinity of the equipment by vehicle, followed by manual rolling. This method is labor-intensive and carries risks of cylinder slippage, personnel falls, or valve damage when using unpaved roads (e.g., grass, gravel ground); the other is to use wheeled cylinder trolleys along fixed roads. However, these trolleys are poorly adapted to uneven terrain, easily causing cylinders to tip over due to bumps, and are also difficult to use to overcome obstacles. Both methods are highly dependent on terrain and have poor transport stability, resulting in low handling efficiency and significant safety hazards when handling gas cylinders.

[0003] To address this issue, Chinese utility model patent application CN201720110977.8 discloses a tracked gas cylinder transport vehicle, comprising a tracked walking device, a vehicle body, a gas cylinder support module, a tail wheel module, and an electrical module. The tracked walking device includes tracks, drive wheels, support rollers, track rollers, tension rollers, guide rails, a tensioning and buffer device, and a vehicle body suspension. The electrical module includes a stepper motor, an electrical control system, and a battery pack. The gas cylinder support module includes a movable support, an operating push rod, and a gear slot. This device moves using tracks made of integrally cast anti-slip rubber, enabling stable movement under complex road conditions. This allows for smooth travel on uneven surfaces, effectively preventing gas cylinders from tipping over due to bumps, thus effectively solving the problems existing in the prior art.

[0004] However, this gas cylinder transport vehicle still has the following problems in actual use: When the gas cylinders are moved onto the gas cylinder transport vehicle, they need to be lifted and moved manually. The gas cylinders are quite heavy, weighing about 50 kilograms when empty and about 100 kilograms when full. This makes the labor intensity of the workers high during the moving process and can easily cause them to suffer injuries such as muscle strain. Summary of the Invention

[0005] To address the aforementioned problems in the existing technology, the present invention provides an all-terrain adaptive tracked gas cylinder transport vehicle.

[0006] The technical solution of the present invention is as follows: An all-terrain adaptive tracked gas cylinder transport vehicle includes a tracked traveling assembly and a frame mounted on the tracked traveling assembly. The frame is provided with a gas cylinder placement assembly for placing gas cylinder bodies, a gas cylinder transport assembly for transporting gas cylinder bodies, and a drive assembly for moving the gas cylinder transport assembly on the frame. The gas cylinder transport assembly, in conjunction with the drive assembly, can transport gas cylinder bodies on the ground to the gas cylinder placement assembly and can transport gas cylinder bodies in the gas cylinder placement assembly to the ground.

[0007] Furthermore, the gas cylinder placement assembly includes several fixed posts fixedly mounted on the vehicle frame. The fixed posts are vertically mounted on the vehicle frame and are distributed in a rectangular structure on the vehicle frame. Each rectangular structure is used to place a gas cylinder body, and the height of the fixed post is set lower than the height of the gas cylinder body.

[0008] Furthermore, when the gas cylinder body is located within the rectangular structure formed by the fixed column, it is tied together with the fixed column using straps.

[0009] Furthermore, the gas cylinder handling assembly includes a gantry frame mounted on a vehicle frame, a winch mounted on the top of the gantry frame, and a fixing clamp for clamping the gas cylinder body at the end of the steel rope wound on the winch. After the fixing clamp clamps the gas cylinder body, the winch can change the horizontal height of the gas cylinder body by changing the horizontal height of the fixing clamp.

[0010] Furthermore, the fixing clamp includes a mounting ring, which is fixedly connected to the end of the steel rope. Below the mounting ring, there are also symmetrically arranged fixing half-rings, with the inner rings of the two fixing half-rings facing each other. Rubber pads are provided on the inner rings of both fixing half-rings. The corresponding ends of the two fixing half-rings are hinged together by a hinge structure so that the two fixing half-rings can fold and open. The outer rings of both fixing half-rings are provided with lifting lugs. The mounting ring and the two lifting lugs are connected together by lifting ropes. When the gas cylinder body is inserted into the two fixing half-rings, the rubber pads on both sides can be tightly fitted against the outer wall of the gas cylinder body.

[0011] Furthermore, the rubber pad is vulcanized, the thickness of the rubber pad is at least 15mm, the coefficient of friction of the rubber pad is μ≥0.8, and anti-slip stripes are provided on the sidewalls of the two rubber pads that are in close contact.

[0012] Furthermore, the front end of the vehicle frame is provided with a working port for placing the gas cylinder body. The gas cylinder handling assembly, in conjunction with the drive assembly, moves the gas cylinder body in the working port into the gas cylinder placement assembly and moves the gas cylinder body in the gas cylinder placement assembly into the working port.

[0013] Furthermore, the drive assembly includes a first hydraulic slide rail slider module disposed on the top of the gantry frame. The first hydraulic slide rail slider module is arranged along the width direction of the frame, and the winch is disposed on the slider in the first hydraulic slide rail slider module.

[0014] Furthermore, the drive assembly also includes second hydraulic slide rail slider modules symmetrically arranged on the frame. The two second hydraulic slide rail slider modules are arranged along the length of the frame. The bottom ends of the two sides of the gantry are respectively set on the sliders in the second hydraulic slide rail slider modules at the corresponding side positions. The two second hydraulic slide rail slider modules move synchronously when they are working.

[0015] Furthermore, the frame is also equipped with a hydraulic control mechanism, and the hydraulic drive mechanism is connected to the first hydraulic slide rail slider module and the second hydraulic slide rail slider module through pipes. The hydraulic drive mechanism is used to control the operation of the first hydraulic slide rail slider module and the second hydraulic slide rail slider module.

[0016] The present invention has the following beneficial effects: This invention, by installing a gas cylinder placement component, a gas cylinder handling component, and a drive component on a vehicle frame, allows the gas cylinder to be moved onto the vehicle frame when necessary. The gas cylinder handling component, through the cooperation of a winch and a fixing clamp, lifts the gas cylinder to a height suitable for entry onto the vehicle frame. The drive component moves the winch and gantry frame accordingly, thus moving the gas cylinder onto the vehicle frame and to a suitable position on the gas cylinder placement component. Once the gas cylinder is in the appropriate position, the winch and fixing clamp work together to place the gas cylinder into the gas cylinder placement component, completing the gas cylinder handling process. Compared to existing technologies, this invention eliminates the need for manual handling of the gas cylinder onto the vehicle frame, reducing worker fatigue and protecting worker health.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] Example: Please refer to Figures 1-4 This embodiment provides an all-terrain adaptive tracked gas cylinder transport vehicle, including a tracked walking assembly 1 and a frame 2 fixedly mounted on the tracked walking assembly 1. When the tracked walking assembly 1 is working, it can drive the frame 2 to move accordingly. The frame 2 is provided with a gas cylinder placement assembly for placing the gas cylinder body 12, a gas cylinder transport assembly for transporting the gas cylinder body 12, and a drive assembly for driving the gas cylinder transport assembly to move on the frame 2. The gas cylinder transport assembly, in conjunction with the drive assembly, can transport the gas cylinder body 12 on the ground to the gas cylinder placement assembly and can transport the gas cylinder body 12 in the gas cylinder placement assembly to the ground, thereby achieving the purpose of eliminating the need for manual handling of the gas cylinder body 12, which can reduce the labor intensity of workers and ensure the health of workers as much as possible.

[0021] In this embodiment, the gas cylinder placement assembly includes several fixing posts 3 fixedly mounted on the frame 2. The specific number of fixing posts 3 is set according to the actual situation, such as matching the number of gas cylinder bodies 12 that need to be placed on the frame 2. Each fixing post 3 is vertically mounted on the frame 2, and the fixing posts 3 are distributed in a rectangular structure on the frame 2, that is, the fixing posts 3 form several rectangular structures on the frame 2, and each rectangular structure is used to place one gas cylinder body 12. In actual use, the fixing posts 3 can also be distributed in other structures, such as triangles, pentagons, etc., and the specific arrangement can be selected according to the actual situation. The height of the fixing posts 3 is set lower than the height of the gas cylinder body 12 to facilitate the subsequent connection of gas cylinder bodies 12 to gas pipes and other devices on the frame 2.

[0022] To ensure that the gas cylinder body 12 can be fixed on the frame 2, in this embodiment, when the gas cylinder body 12 is located within the rectangular structure formed by the fixing post 3, it is tied together with the fixing post 3 by using straps. Thus, it can be stably placed on the frame 2 through the fixed connection with the fixing post 3, and will not tip over due to vibration during transportation.

[0023] In this embodiment, the gas cylinder handling assembly includes a gantry 4 mounted on the frame 2. The gantry 4 is arranged along the width direction of the frame 2. A winch 5 is mounted on the top of the gantry 4. A fixing clamp 7 for clamping the gas cylinder body 12 is mounted on the end of the steel rope 6 wound on the winch 5. After the fixing clamp 7 clamps the gas cylinder body 12, the winch 5 can change the horizontal height of the gas cylinder body 12 by changing the horizontal height of the fixing clamp 7. At the same time, the fixing clamp 7 can also further clamp the gas cylinder body 12 with the help of the upward lifting force generated by the winch 5.

[0024] In this embodiment, the fixing clamp 7 includes a mounting ring 71, which is fixedly connected to the end of the steel rope 6. Below the mounting ring 71, there are also symmetrically arranged fixing half-rings 72. The radius of the mounting ring 71 is smaller than the radius of the two fixing half-rings 72. Both fixing half-rings 72 are made of Q345B stainless steel with a thickness of 8mm, thus possessing good rigidity and being less prone to deformation or breakage, thereby ensuring a good clamping effect. The inner rings of the two fixing half-rings 72 are arranged opposite each other, and rubber pads 73 are fixedly installed on the inner rings of both fixing half-rings 72. The shape of the rubber pads 73 on both sides is adapted to the corresponding fixing half-rings 72. The corresponding ends of the two fixed half rings 72 are hinged together by a hinge structure 74 so that the two fixed half rings 72 can fold and open. The outer ring of the two fixed half rings 72 is provided with a lifting lug 75. The mounting ring 71 is connected to the two lifting lugs 75 by a lifting rope 76. When the gas cylinder body 12 is put into the two fixed half rings 72, the rubber pads 73 on both sides can be tightly attached to the outer wall of the gas cylinder body 12.

[0025] With the aforementioned fixing clamp 7 in use, the operator places the two fixing half-rings 72 on the outside of the gas cylinder body 12, ensuring that the rubber pads 73 on both sides are tightly fitted against the outer wall of the gas cylinder body 12. Afterward, the operator starts the winch 5. The winch 5 drives the mounting ring 71 upward via the steel rope 6. The mounting ring 71, via the suspension rope 76, can drive the two fixing half-rings 72 upward. Since the radius of the mounting ring 71 is smaller than the radius of the two fixing half-rings 72, the mounting ring 71, with the help of the suspension rope 76, secures the two fixing half-rings 72 to the outside. The lifting force applied by the fixed half-ring 72 is in the inclined direction. At this time, the two fixed half-rings 72 will fold and close together under the action of this lifting force and the action of the hinge structure 74. This allows the rubber pads 73 on both sides of the fixed half-rings 72 to be further pressed against the outer wall of the gas cylinder body 12, effectively converting the clamping force on the gas cylinder body 12 into friction. As a result, the two fixed half-rings 72 and the rubber pads 73 can firmly hold the gas cylinder body 12, so that the gas cylinder body 12 can be driven to follow the corresponding movement under the action of friction.

[0026] To ensure that the rubber pad 73 can provide sufficient friction, in this embodiment, the rubber pad 73 is vulcanized, the thickness of the rubber pad 73 is at least 15mm, the coefficient of friction of the rubber pad 73 is μ≥0.8, and anti-slip stripes are provided on the sidewalls of the two rubber pads 73 that are in close contact. The anti-slip stripes can be arranged in an interlaced manner, or they can be processed on the rubber pad 73 according to the following processing function.

[0027] The expression for the processing function is:

[0028] In the formula, A represents the amplitude of the sine function sinBx+C, which determines the height of the anti-slip stripe undulation, thus affecting the protrusion and depression of the stripe. The value of A is 3 to 5. B represents the period parameter, which determines the density of the stripe, thus affecting the contact point between the rubber pad 73 and the outer wall of the gas cylinder body 12. The value of B is 0.6 to 1.2. C represents the phase offset, which is used to adjust the starting position of the anti-slip stripe. Its specific value is related to the overall circumference of the rubber pad 73, and the common value range is 0 to π / 2. m represents the slope, which determines whether the anti-slip stripe is horizontal. It can be selected and set according to the actual needs of the weight of the gas cylinder body 12 to be transported. Since horizontal stripes can evenly distribute pressure and provide a good anti-slip effect, in this embodiment, the value of m is 0. D represents the vertical offset, which determines the height of the anti-slip stripe to improve the load-bearing capacity of the anti-slip stripe. The value of D is 1.2 to 2.

[0029] To facilitate the handling process, in this embodiment, a working port 8 for placing the gas cylinder body 12 is provided on the front end of the vehicle frame 2. With the working port 8, during the handling of the gas cylinder body 12, the vehicle frame 2 moves to the storage area of ​​the gas cylinder body 12 via the tracked walking assembly 1, and then the working port 8 enters the storage area and moves to a suitable position. Afterwards, the gas cylinder handling assembly, in conjunction with the drive assembly, moves the gas cylinder body 12 from the working port 8 to the gas cylinder placement assembly or from the gas cylinder placement assembly to the working port 8, according to actual needs.

[0030] In this embodiment, the drive assembly includes a first hydraulic slide rail slider module 9 fixedly mounted on the top of the gantry 4, a second hydraulic slide rail slider module 10 symmetrically arranged on the frame 2, and a hydraulic control mechanism 11 fixedly mounted on the rear end of the frame 2. The first hydraulic slide rail slider module 9 is arranged along the width direction of the frame 2, and the winch 5 is fixedly mounted on the slider in the first hydraulic slide rail slider module 9. When working, the first hydraulic slide rail slider module 9 can drive the winch 5 to move along the width direction of the frame 2. The two second hydraulic slide rail slider modules 10 are arranged along the length direction of the frame 2. The bottom ends of the two sides of the gantry 4 are respectively mounted on the sliders in the corresponding second hydraulic slide rail slider modules 10. When working, the two second hydraulic slide rail slider modules 10 move synchronously, and when working, they can drive the gantry 4 to move along the length direction of the frame 2. The hydraulic drive mechanism is connected to the first hydraulic slide rail slider module 9 and the second hydraulic slide rail slider module 10 by pipes. The hydraulic drive mechanism is used to control the operation of the first hydraulic slide rail slider module 9 and the second hydraulic slide rail slider module 10.

[0031] The working principle of this embodiment is as follows: When it is necessary to move the gas cylinder body 12 onto the chassis 2, the operator controls the tracked walking assembly 1 to move the chassis 2 to the storage area of ​​the gas cylinder body 12 to be moved, and then the working port 8 enters this storage area so that the gas cylinder body 12 can be moved into the working port 8. Then, the operator controls the hydraulic drive mechanism to start working, which controls the second hydraulic slide rail slider module 10 to move the gantry 4. After the gantry 4 moves to the position of the winch 5 above the working port 8, the second hydraulic slide rail slider module 10 stops working. Then, the operator controls the winch 5 to start working, lowering the fixing clamp 7 to a suitable height. Then, the operator puts the fixing clamp 7 on the outside of the gas cylinder body 12, and after the rubber pads 73 on both sides are pressed tightly against the outer wall of the gas cylinder body 12, the operator controls the winch 5 to start working, raising the fixing clamp 7 to a suitable height, thereby raising the gas cylinder body 12 to the required height. After this, the operator controls the hydraulic drive mechanism to start working, causing the first hydraulic slide rail slider module 9 to start working to drive the winch 5 to move, and causing the second hydraulic slide rail slider module 10 to start working to drive the gantry 4 to move, so as to move the gas cylinder body 12 above the gas cylinder placement assembly. Then, the operator controls the winch 5 to start working, causing it to lower the gas cylinder body 12 into the gas cylinder placement assembly. When the gas cylinder body 12 is not in contact with the frame 2, the winch 5 can always provide an upward lifting force for the fixing clamp 7, so the fixing clamp 7 can still firmly hold the gas cylinder body 12. When the gas cylinder body 12 contacts the frame 2, the winch 5 can no longer provide an upward lifting force for the fixing clamp 7, and the fixing clamp 7 can be removed from the gas cylinder body 12. After that, repeat the above steps to place all the gas cylinder bodies 12 that need to be moved into the gas cylinder placement assembly. Then, the operator uses straps to tie each gas cylinder body 12 to the fixing post 3, and the required transportation work can be carried out.

[0032] Similarly, when it is necessary to move the gas cylinder body 12 off the chassis 2, the operator can start working by controlling the track walking assembly 1 to move the chassis 2 to the storage area of ​​the gas cylinder body 12 in the corresponding position. Then, the working port 8 enters this storage area. Afterwards, the hydraulic control mechanism 11 is used in conjunction with the fixed clamp 7, winch 5 and other structures to move the gas cylinder body 12 in the gas cylinder placement assembly into the working port 8, thereby realizing the removal of the gas cylinder body 12 off the chassis 2 and into the required storage area.

[0033] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
