[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The utility model embodiment provides a gas cylinder transport vehicle 10. The gas cylinder transport vehicle is used, for example, to transport or even stack empty cylinders. Specifically, Figure 1a , Figure 1b , Figure 1c and Figure 1d As shown, the gas cylinder transport vehicle 10 includes, for example: a transport vehicle body 100 , a lifting assembly 200 and a clamping and fixing assembly 400 .

[0031] Among them, the transport vehicle body 100, for example, includes the main components of the gas cylinder transport vehicle 10, such as a frame, a travel unit, a power supply unit, etc. The transport vehicle body 100, for example, can adopt a mature technical solution in the prior art to realize the normal driving function of the vehicle, and its specific structure is not repeated here. The lifting component 200 is connected to one end of the transport vehicle body 100. The lifting component 200 can move up and down relative to the transport vehicle body 100. The lifting component 200 is used to drive the clamping and fixing component 400 to realize the up and down lifting function.

[0032] Specifically, Figure 1d , Figure 2a-2c As shown, the clamping and fixing assembly 400 is used, for example, to clamp and fix the gas cylinder to be transported, so as to realize the transport and even stacking of the gas cylinder. Specifically, the clamping and fixing assembly 400 includes, for example, a first power device 410, a linear distance adjustment mechanism 420, at least one first transport arm 430 and at least one second transport arm 440. It is worth mentioning that the at least one first transport arm 430 can be, for example, at least one or more first transport arms 430, and in this embodiment, a first transport arm 430 is used as an example for description; the at least one second transport arm 440 can be, for example, at least one or more second transport arms 440, and in this embodiment, a second transport arm 440 is used as an example for description. Among them, the first power device 410 is connected to the rotating assembly 300. The first power device 410 is, for example, a driving motor such as a stepping motor, which is used to provide power for the linear distance adjustment mechanism 420. The linear distance adjustment mechanism 420 is connected to the first power device 410. At least one first transport arm 430 is connected to one end of the linear distance adjustment mechanism 420; at least one second transport arm 440 is connected to the other end opposite to the linear distance adjustment mechanism 420 and is arranged opposite to the at least one first transport arm 430. The at least one first transport arm 430 and the at least one second transport arm 440 are used to clamp and fix the two ends of the steel cylinder when transporting the steel cylinder. Typically, as Figure 3As shown, the cylinder is, for example, a columnar cylinder, the outer contour of the bottom is cylindrical, the neck is conical, and the cross-sectional size of the top is smaller than the cross-sectional size of the bottom. Therefore, one of the first carrying arm 430 and the second carrying arm 440 fixes the bottom of the cylinder, and the other of the first carrying arm 430 and the second carrying arm 440 fixes the top and / or neck of the cylinder. The linear distance adjustment mechanism 420 is used to adjust the distance between at least one first carrying arm 430 and at least one second carrying arm 440, so that the gas cylinder transporter 10 can fix both ends of the cylinder in the length direction of the cylinder. The user can fix the gas cylinder to be transported by at least one first carrying arm 430 and at least one second carrying arm 440. Then, the user drives the gas cylinder transporter 10 to transport the gas cylinder to be transported to the destination, and then the user controls the lifting assembly 200 and the rotating assembly 300 to control the height and state of the gas cylinder to be transported, so as to stack the cylinder more conveniently.

[0033] Therefore, the embodiment of the utility model solves the problems of heavy labor, unsafety or high equipment cost in the transportation and stacking of cylinders by providing a lifting assembly 200, a rotating assembly 300 and a clamping and fixing assembly 400, so that the gas cylinder transport vehicle 10 has both a transporting function and a stacking function, which reduces the labor of transporting and stacking cylinders, reduces equipment costs, and improves the safety of cylinder stacking.

[0034] Based on the above, Figure 2b As shown, one of the at least one first transport arm 430 and the at least one second transport arm 440 is provided with a conical hole matching the neck of the gas cylinder to be transported, and the other of the at least one first transport arm 430 and the at least one second transport arm 440 is provided with a circular hole matching the bottom of the gas cylinder to be transported. That is, the size of the conical hole is consistent with the size of the neck, and the size of the circular hole is consistent with the size of the bottom of the cylinder. When clamping and fixing the cylinder, the bottom of the gas cylinder to be transported can be inserted into the matching circular hole, and the neck of the gas cylinder to be transported can be inserted into the conical hole. For example, at least one first transport arm 430 is provided with a conical hole 431, and at least one second transport arm 440 is provided with a circular hole 441. Figure 2c As shown. For another example, at least one second transport arm 440 is provided with a conical hole 431, and at least one first transport arm 430 is provided with a circular hole 441. In this way, at least one first transport arm 430 and at least one second transport arm 440 can better match the outer contour of the cylinder, thereby improving the stability and safety of the cylinder transportation.

[0035] Specifically, the straight-line distance adjustment mechanism 420 includes, for example, a housing 421, an adjusting gear 422, a first rack 423 and a second rack 424. The housing 421 has a lower surface 4211, and a first opening 42111 and a second opening 42112 are provided on the lower surface 4211. The adjusting gear 422 is, for example, a common involute standard gear. The adjusting gear 422 is disposed inside the housing 421. The adjusting gear 422 is connected to the first power device 410, for example, by a flat key connected to the rotating shaft 322 of the first power device 410. The first rack 423 is disposed in the housing 421 and meshed with the adjusting gear 422. The second rack 424 is disposed in the housing 421 and meshed with the adjusting gear 422. The second rack 424 and the first rack 423 are respectively located on opposite sides of the adjusting gear 422. Figure 2b and Figure 2c As shown, the first rack 423 is located on the upper side of the adjusting gear 422, and the second rack 424 is located on the lower side of the adjusting gear 422. The second rack 424 and the first rack 423 are simultaneously meshed with the adjusting gear 422 to form a gear transmission mechanism. The at least one first transport arm 430 passes through the first opening 42111 and is connected to the first rack 423, and the at least one second transport arm 440 passes through the second opening 42112 and is connected to the second rack 424. When the first power device 410 drives the adjusting gear 422 to rotate, the second rack 424 and the first rack 423 simultaneously move toward or away from each other, so that the distance D between the at least one first transport arm 430 and the at least one second transport arm 440 can be reduced or increased. In this way, before clamping the gas cylinder to be transported, the user can control the linear distance adjustment mechanism 420 to increase the distance D between the at least one first transport arm 430 and the at least one second transport arm 440, so as to better align the at least one first transport arm 430 and the at least one second transport arm 440 with the gas cylinder to be transported, and then control the linear distance adjustment mechanism 420 to reduce the distance D between the at least one first transport arm 430 and the at least one second transport arm 440 to complete the clamping and fixation of the gas cylinder to be transported, thereby improving the convenience of clamping and fixing the cylinder.

[0036] In addition, if Figure 4 As shown in the figure, when stacking cylinders, pads need to be placed between the cylinders. After stacking one layer of cylinders, the pads are usually placed on the cylinders manually to stack the next layer of cylinders. Therefore, another person needs to be arranged to assist in the cylinder stacking work. In order to further reduce labor costs, such as Figure 2a , Figure 2b and Figure 2cAs shown, the gas cylinder transport vehicle 10 provided in the embodiment of the utility model can also be provided with a first pad plate picking arm 500 and a second pad plate picking arm 600 for picking up and laying pad plates. The shell 421 also includes a side surface 4212 away from the transport vehicle body 100, and the side surface 4212 is connected to and adjacent to the lower surface 4211. The side surface 4212 is also provided with a third opening 42121 and a fourth opening 42122. The first pad plate picking arm 500 is connected to the first rack 423 through the third opening 42121. The second pad plate picking arm 600 is connected to the second rack 424 through the fourth opening 42122. The first pad plate picking arm 500 and the second pad plate picking arm 600 are arranged opposite to each other. In this way, when it is necessary to lay the pad, the user controls the rotating assembly 300 of the gas cylinder transporter 10 to rotate 180 degrees, and then controls the first pad picking arm 500 and the second pad picking arm 600 to pick up the pad and lay it on the upper cylinder through the lifting assembly 200, the first power device 410 and the straight-line distance adjustment mechanism 420, and then controls the rotating assembly 300 to rotate 180 degrees to continue the cylinder transportation and stacking work. By arranging the first pad picking arm 500 and the second pad picking arm 600 on the first rack 423 and the second rack 424 respectively, not only the mechanized function of pad picking and laying is realized, saving labor costs, but also the cylinder transportation and stacking functions and pad picking and laying functions are realized through a set of power and transmission components, further improving the multifunctionality and equipment utilization rate of the gas cylinder transporter 10, and saving equipment costs.

[0037] Further, in the horizontal direction, the first pad picking arm 500 is located between the at least one first transporting arm 430 and the second pad picking arm 600 , and the second pad picking arm 600 is located between the at least one second transporting arm 440 and the first pad picking arm 500 .

[0038] In one embodiment of the present invention, Figure 1d , Figure 4 and Figure 5As shown, the gas cylinder transport vehicle 10 may further include a rotating assembly 300. The rotating assembly 300 is connected between the lifting assembly 200 and the clamping and fixing assembly 400. The rotating assembly 300 is used to drive the clamping and fixing assembly 400 to realize the rotation function. Specifically, the rotating assembly 300 includes: a connecting member 310, a second power device 320 and a rotating member 330. Among them, the connecting member 310 is connected to the lifting assembly 200. The second power device 320 is arranged on the connecting member 310. The second power device 320 is, for example, a driving motor such as a stepping motor, which is used to drive the rotating member 330 to rotate. The rotating member 330 is connected to the second power device 320. The rotating member 330 can rotate relative to the connecting member 310 under the drive of the second power device 320. The first power device 410 is arranged on the rotating member 330.

[0039] Furthermore, if Figure 5 As shown, the connecting member 310 is provided with a receiving cavity (not shown in the figure), and the second power device 320 has a fixed portion 321 and a rotating shaft 322, wherein the fixed portion 321 is provided in the receiving cavity, and the rotating shaft 322 is rotatably connected to the fixed portion 321 and extends out of the receiving cavity. In addition, the rotating assembly 300 further includes a cover plate 340. The cover plate 340 is connected to the connecting member 310, for example, by a threaded connector. The cover plate 340 covers the fixed portion 321, and the rotating shaft 322 extends out of the cover plate 340 and is connected to the rotating member 330.

[0040] In addition, if Figure 5 As shown, the rotating assembly 300 further includes an axial contact bearing 350, and opposite ends of the axial contact bearing 350 are respectively abutted between the cover plate 340 and the rotating member 330. Such a configuration enables the axial contact bearing 350 to improve the rotation stability of the rotating member 330 relative to the connecting member 310.

[0041] Furthermore, if Figure 6a and Figure 6bAs shown, the lifting assembly 200 includes: a main frame 210, a lead screw 220 and a third power device 230. The main frame 210 is, for example, a rectangular structure with a hollow interior. A connecting portion 211 is provided on one side of the main frame 210. The connecting portion 211 is fixedly connected to the transport vehicle body 100, and is used to provide support for other components of the lifting assembly 200, the rotating assembly 300 and the clamping and fixing assembly 400. The lead screw 220 is rotatably connected to the main frame 210. Specifically, a lead screw threaded hole 311 is provided on the connecting member 310, and the lead screw 220 is inserted into the lead screw threaded hole 311. The third power device 230 is provided on the main frame 210 and connected to one end of the lead screw 220. The second power device 320 is, for example, a drive motor such as a stepping motor, which is used to drive the lead screw 220 to rotate relative to the main frame 210. Driven by the third power device 230 , the lead screw 220 can drive the connecting member 310 to move up and down relative to the main frame 210 , so that the lifting assembly 200 drives the rotating assembly 300 and the clamping and fixing assembly 400 to move up and down.

[0042] Typically, as shown in FIG6 , the gas cylinder transport vehicle 10 further includes a main controller 600, which is disposed on the transport vehicle body 100 and electrically connected to the first power device 410, the second power device 320 of the rotating assembly 300, and the third power device 230 of the lifting assembly 200, so that the clamping and fixing assembly 400, the lifting assembly 200, and the rotating assembly 300 can be controlled. The main controller 610 is, for example, an electronic component such as an MCU or a DSP having data processing and control functions. At least part of the control instructions of the gas cylinder transport vehicle 10 are generated and sent by the main controller 600.

[0043] It should also be noted that the various specific technical features described in the above specific implementation methods can be combined in any suitable manner without contradiction.
