Detailed implementation mode

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment The present invention provides an anti-tilting device for an arrow body vertical transporter. Refer to Figure 1 , which is installed between the suspension and the vehicle frame 500, and multiple are provided. During the working process, through the coordinated cooperation of multiple anti-tilting devices, the vehicle frame 500 is controlled to maintain a horizontal state.

[0019] Refer to [[ID=I6]] Figure 1 - Figure 2 , the anti-tilting device for the arrow body vertical transporter includes a mounting base 100 fixedly connected to the suspension. A vibration damping component 200 and a leveling component 300 are arranged between the mounting base 100 and the vehicle frame 500. One end of the vibration damping component 200 is fixedly connected to the vehicle frame 500, and the other end is connected to the moving end of the leveling component 300. The leveling component 300 is fixedly installed on the mounting base 100; a horizontal sensor is arranged on the vehicle frame 500, and the horizontal sensor detects the levelness of the vehicle frame 500. During operation, the levelness of the vehicle frame 500 is detected in real time through the horizontal sensor. When it is found that the vehicle frame 500 has a certain tilt angle, the horizontal state of the vehicle frame 500 is quickly adjusted through the cooperation of the vibration damping component 200 and the leveling component 300, so as to ensure that the vehicle frame 500 always remains horizontal during the process of transporting the arrow body, greatly improving the safety during the process of transporting the arrow body. Among them, multiple horizontal sensors can be arranged and are arranged at different positions of the vehicle frame 500, so as to more accurately judge whether the vehicle frame 500 is tilted.

[0020] The vibration damping component 200 includes a support disc 210, a support column 220, a first spring 230 and a sliding sleeve 240.

[0021] One side of the support disk 210 is ball-hinged to the lower side of the vehicle frame 500, and the other side of the support disk 210 is fixedly installed with one end of the support column 220. Specifically, an installation column 211 is fixed on one side of the support disk 210 close to the vehicle frame 500, and a hinge ball 212 is fixed at one end of the installation column 211 away from the support disk 210; a limit frame 250 is fixed on one side of the vehicle frame 500 close to the support disk 210, a spherical hole 251 is opened in the limit frame 250, a communication port 252 is opened on one end face of the limit frame 250 close to the support disk 210, and the communication port 252 is communicated with the spherical hole 251; the hinge ball 212 is located in the spherical hole 251. When the vehicle frame 500 is adjusted, a certain included angle can exist between the support disk 210 and the vehicle frame 500, and during the adjustment process, the stability of the vehicle frame 500 can be ensured.

[0022] One end of the support column 220 away from the support disk 210 is slidably connected in the sliding sleeve 240; one end of the sliding sleeve 240 close to the support disk 210 has an opening, and the end away from the support disk 210 is in a closed state, which is convenient for connecting the leveling assembly 300.

[0023] The first spring 230 is a compression spring, one end of the first spring 230 abuts against the support disk 210, and the other end abuts against the end of the sliding sleeve 240; the moving end of the leveling assembly 300 is connected to the sliding sleeve 240. By providing the damping assembly 200, the damping effect of the transport vehicle can be further increased, the stability of the transport vehicle can be improved, and at the same time, a buffering effect can be achieved during the process of adjusting the level of the vehicle frame 500, avoiding affecting the rocket body during the adjustment process.

[0024] The leveling assembly 300 includes a support sleeve 310, an installation sleeve 320, a sliding block 330 and a first telescopic member 340.

[0025] Both sides of the mounting seat 100 are fixedly connected to the suspension. An installation hole 110 is opened in the middle of the mounting seat 100. The support sleeve 310 and the installation sleeve 320 respectively cover the installation hole 110 and are both fixedly connected to the mounting seat 100. The support sleeve 310 and the installation sleeve 320 are respectively located on both sides of the mounting seat 100. The support sleeve 310 is located on the side close to the vehicle frame 500, and the installation sleeve 320 is located on the side away from the vehicle frame 500.

The first telescopic member 340 is fixedly installed inside the installation sleeve 320, and the telescopic end of the first telescopic member 340 passes through the installation hole 110 and is fixedly connected to the sliding block 330. When the first telescopic member 340 extends or contracts, it can drive the sliding block 330 to slide. During the sliding process, the height of the sliding sleeve 240 is controlled. When the height of the sliding sleeve 240 changes, the elastic potential energy of the first spring 230 changes, thereby changing the height value of the vehicle frame 500. During the adjustment process, each time the telescopic amount of the first telescopic member 340 is controlled to be as small as possible, and at the same time, in cooperation with the damping assembly 200, the impact on the smoothness of the arrow body is reduced, and at the same time, the purpose of adjusting the level of the vehicle frame 500 can be achieved.

[0027] In one embodiment, the sliding block 330 and the sliding sleeve 240 are fixedly connected. By fixedly connecting the two, the adjustment accuracy can be further improved.

[0028] See Figure 1 - Figure 5 , adjustment assemblies 400 are respectively arranged on both sides of the support disc 210 and under the vehicle frame 500. The adjustment assemblies 400 are connected to the sliding sleeve 240, and the connection position is always located outside the support sleeve 310.

[0029] Specifically, the adjustment assembly 400 includes a support tube 410, a buffer block 420, a second spring 430, and a linkage rod 440.

[0030] Support blocks 450 are fixedly installed at both ends of the support tube 410, and are fixedly connected to the vehicle frame 500 through the support blocks 450; so that the support tube 410 is parallel to the length direction of the vehicle frame 500. The buffer block 420 and the second spring 430 are sleeved on the support tube 410. The buffer block 420 is located at one end of the second spring 430 close to the support disc 210. The buffer block 420 and the support tube 410 can rotate relative to each other and can also slide relative to each other. The second spring 430 is a compression spring. One end of the linkage rod 440 is hinged to the sliding sleeve 240, and the other end is hinged to the buffer block 420. Through the above technical solutions, during the working process or when adjusting the level of the vehicle frame 500, the purpose of damping can be achieved, further improving the stability of the arrow body. At the same time, during the adjustment process, the impact on the arrow body can be reduced.

[0031] In one embodiment, the adjustment assembly 400 further includes an adjustment block 460 and a second telescopic member 470.

[0032] An adjustment hole 411 is formed inside the support tube 410, and the adjustment hole 411 penetrates through a support block 450. A long groove 412 is formed on the side wall of the support tube 410. The long groove 412 communicates with the adjustment hole 411, and four long grooves 412 are arranged at equal angular intervals. The adjustment block 460 is in a cross shape. The middle part of the adjustment block 460 is located inside the adjustment hole 411. The four end parts of the adjustment block 460 pass through the long groove 412 and abut against the second spring 430. The adjustment block 460 and the buffer block 420 are located at both ends of the second spring 430. The telescopic end of the second telescopic member 470 is connected to the adjustment block 460.

[0033] By arranging the adjustment assemblies 400 on both sides of the support disc 210, when adjusting the level of the vehicle frame 500, the cooperation adjustment is carried out through the adjustment assemblies 400 on both sides. That is, when the second telescopic member 470 changes the compression amount of the second spring 430, the supporting force of the vehicle frame 500 on both sides of the support disc 210 can be controlled, so as to achieve the purpose of assisting in adjusting the levelness of the vehicle frame 500. At the same time, after adjustment, the second springs 430 on both sides can be ensured to be evenly stressed, improving their service life.

[0034] The first telescopic member 340 and / or the second telescopic member 470 is a hydraulic cylinder. During operation, the telescopic end can be controlled to extend, shorten or stop at any time.

[0035] The present invention provides an anti-tilting device for an arrow body upright transporter. Through the vibration damping assembly 200, the leveling assembly 300 and the adjustment assembly 400 arranged between the suspension and the vehicle frame 500, when transporting the arrow body, the vibration damping effect can be further achieved, improving the stability of the transportation process. When the vehicle frame 500 is in a tilted state, the vehicle frame 500 can be quickly adjusted through the leveling assembly 300 and the adjustment assembly 400 to keep the vehicle frame 500 level. During the adjustment process, the first spring 230 and the second spring 430 are used for buffering, that is, the stability of the arrow body is ensured, and at the same time, the level adjustment of the vehicle frame 500 can be successfully completed. Through this solution, during the transportation of the arrow body, the purpose of preventing the vehicle frame 500 from tilting can be achieved, and the safety during the transportation of the arrow body can be guaranteed to the greatest extent.
