Description

Technical Field

[0001] The utility model relates to the technical field of industrial equipment, in particular to an industrial gas bottle cart. Background Art

[0002] Industrial gas cylinders are containers used to store and transport gases for various industrial purposes. These gases can be liquefied, compressed or liquid gases, including but not limited to oxygen, acetylene, nitrogen, argon, and methane. Industrial gas cylinders are usually made of corrosion-resistant metal materials, such as steel or aluminum alloys, and are specially designed and processed to ensure safety and stability. In the process of transferring and transporting liquid supply gas cylinders, special cart equipment is required for transfer and transportation.

[0003] At present, most of the existing industrial gas cylinder trolleys are provided with a single or multiple circular grooves on the trolley. The gas cylinder is placed in the groove and transferred by pushing and pulling. However, the gas cylinder is not fixed, which leads to shaking and falling off during the transportation process. At the same time, it does not have the function of quickly unloading the gas cylinder, and manual operation is required, which has certain defects. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the shortcomings of the prior art, the utility model provides an industrial gas cylinder cart, which has the advantages of improving the stability of gas cylinder transportation, quickly unloading gas cylinders, and reducing manual physical exertion. It solves the problem that the cart currently used for transporting industrial gas cylinders has a single structure, does not have the function of providing fixed protection for gas cylinders, and requires manual unloading of gas cylinders, which requires a lot of physical exertion.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an industrial gas cylinder cart, comprising a lower bracket assembly, an upper bracket assembly, a supporting assembly and a limiting assembly, the lower bracket assembly comprising a lower bracket, a support rod fixed to the side of the lower bracket, a handle fixed to one end of the support rod, and a support rod fixed to the bottom of the lower bracket, a mounting rod fixed to one end of the support rod, and a movable wheel movably hinged on the mounting rod. The gas cylinder is placed on the lower bracket, and the lower bracket plays a role of supporting the gas cylinder. By holding the handle, the lower and upper bracket assemblies are tilted, and under the push-pull force, the movable wheels drive the device as a whole to move.

[0008] The upper bracket assembly includes an upper bracket movably connected to the side of the lower bracket, and the upper bracket and the lower bracket are movably hinged by a hinge, one end of the hinge is fixed to the side of the upper bracket, and the other end is fixed to the side of the lower bracket, so that the upper and lower brackets can be opened and closed by rotation. When the upper and lower brackets are closed, two circular hollow grooves are formed inside, and the circular hollow grooves are used to place liquid and gas cylinders.

[0009] The supporting assembly includes an electric telescopic rod fixed to the side of the lower bracket, and a supporting plate is movably hinged at the output end of the electric telescopic rod. The electric telescopic rod is used to control the up and down movement of the supporting plate and to adjust the height position of the liquid supply gas cylinder in the upper and lower brackets.

[0010] As a further improvement of the above scheme, a protective plate is fixed in the lower bracket, a mounting groove is opened on the protective plate, a buffer spring is fixed in the mounting groove, a buffer plate is fixed at one end of the buffer spring, and the side of the buffer plate matches the diameter inside the protective plate.

[0011] Through the above technical solution, the protective plate is arc-shaped, which matches the diameter of the groove in the lower bracket. When the gas cylinder is placed on the lower bracket, the side is attached to the buffer plate. The pressure generated at this time presses the buffer plate, which is tightened by the buffer spring to achieve a buffering effect on the gas cylinder.

[0012] As a further improvement of the above solution, a first fixing plate is fixed to the side of the lower bracket, and a second fixing plate is fixed to the side of the upper bracket. Magnetic plates are fixed inside the first and second fixing plates and are attracted to each other.

[0013] Through the above technical solution, the first fixing plates are installed at both ends and the middle of the side of the lower bracket, and the second fixing plates are installed at both ends and the middle of the side of the upper bracket. The first and second fixing plates correspond to each other, and magnetic plates are installed inside the opposite surfaces. When the upper and lower brackets are closed, the magnetic plates are adsorbed and fixed to each other, thereby achieving the effect of preliminary fixing of the upper and lower brackets.

[0014] As a further improvement of the above solution, the lower bracket and the upper bracket are internally threadedly connected with a fixing screw.

[0015] Through the above technical solution, after the upper and lower brackets are closed, the fixing screw is rotated clockwise so that the fixing screw is threadedly connected to the first and second fixing plates, and the two brackets are completely fixed. The fixing screw is rotated counterclockwise so that either end is detached from the fixing plate, so that the upper and lower brackets can be unfolded, thereby achieving the effect of disassembling and assembling the gas cylinder.

[0016] As a further improvement of the above solution, the side of the upper bracket is threadedly connected with a fixing screw.

[0017] Through the above technical solution, the fixing screw is rotated clockwise to move its front end into the bracket and tightly adhere to the side of the gas cylinder, so as to fix gas cylinders of different diameters. After rotating counterclockwise, the front end gradually moves backward and separates from the side of the gas cylinder. At this time, the height of the gas cylinder and the rotation of the bottle body can be adjusted.

[0018] As a further improvement of the above solution, a rubber pad is fixed on the supporting plate and corresponds to the upper and lower brackets.

[0019] Through the above technical solution, the rubber pad has a certain elasticity, and after the top contacts the bottom of the gas cylinder, a concave phenomenon occurs. At the same time, friction resistance is generated between the contact surfaces to avoid shaking and improve the stability of the gas cylinder.

[0020] As a further improvement of the above solution, a connecting block is fixed to the side of the supporting plate, a stabilizing sleeve rod is fixed on the connecting block, and a stabilizing sleeve is fixed to the side of the upper and lower brackets, and the stabilizing sleeve rod is movably sleeved in the stabilizing sleeve.

[0021] Through the above technical solution, when the support plate moves up and down, the stabilizing sleeve rod is inserted into the stabilizing sleeve, so that the support plate is fixed in place to prevent it from rotating. After the stabilizing sleeve rod is separated from the stabilizing sleeve, the support plate can be rotated. When the support plate rotates, the bottom of the gas cylinder loses support, so that the gas cylinder can be unloaded.

[0022] As a further improvement of the above solution, a locking screw is threadedly connected to the side of the stabilizing sleeve, and one end of the locking screw is fitted to the side of the stabilizing sleeve rod.

[0023] Through the above technical scheme, when the locking screw rotates clockwise or counterclockwise, the front end is separated from or pressed against the side of the stabilizing sleeve rod. When the front end is pressed against the side of the stabilizing sleeve rod, the stabilizing sleeve rod is fixed in the stabilizing sleeve. After the front end is separated from the stabilizing sleeve rod, the stabilizing sleeve rod can be separated from the stabilizing sleeve, thereby adjusting the height of the support plate.

[0024] Compared with the prior art, the utility model provides an industrial gas cylinder cart, which has the following beneficial effects:

[0025] 1. The industrial gas cylinder cart has an upper bracket of the same size hinged on the side of the lower bracket. After the upper and lower brackets are closed, they can provide preliminary fixation and protection for the gas cylinders placed inside, and by rotating the fixing screw, the front end of the gas cylinder can be tightly attached to the side of the gas cylinders with different diameters, ensuring the stability of the gas cylinders during transportation and effectively avoiding shaking and falling off.

[0026] 2. The industrial gas cylinder cart is fixed with an electric telescopic rod through the side of the lower bracket. The output end of the electric telescopic rod is movably hinged with a supporting plate. The supporting plate is located directly below the upper and lower brackets. The height of the gas cylinder is adjusted by controlling the telescopic movement of the output end of the electric telescopic rod. The output end moves downward to disengage the stabilizing sleeve rod from the stabilizing sleeve, so that the supporting plate can rotate horizontally. When the device is tilted as a whole and the side of the gas cylinder is not fixed, the supporting plate can be detached from the bottom of the gas cylinder by rotation, thereby realizing rapid unloading of the gas cylinder, effectively reducing the physical effort consumed in manual unloading of the gas cylinder.

[0038] 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 in 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.

[0039] Embodiment 1

[0040] See also Figure 1-6 As shown, the industrial gas cylinder cart proposed in this embodiment includes a lower bracket assembly 1, an upper bracket assembly 2, a supporting assembly 3 and a limiting assembly 4. The lower bracket assembly 1 includes a lower bracket 101, a support rod 102 is fixed to the side of the lower bracket 101, and a hand grip 103 is fixed to one end of the support rod 102. At the same time, a support rod 110 is fixed to the bottom of the lower bracket 101, and a mounting rod 111 is fixed to one end of the support rod 110. A moving wheel 112 is movably hinged on the mounting rod 111. The gas cylinder is placed on the lower bracket 101, and the lower bracket 101 plays a role of supporting the gas cylinder. By holding the handle 103, the lower and upper bracket assemblies are tilted. Under the push-pull force, the moving wheel 112 drives the device as a whole to move.

[0041] The upper bracket assembly 2 includes an upper bracket 201 movably connected to the side of the lower bracket 101. The upper bracket 201 and the lower bracket 101 are movably hinged by a hinge 202. One end of the hinge 202 is fixed to the side of the upper bracket 201, and the other end is fixed to the side of the lower bracket 101, so that the upper and lower brackets can be opened and closed by rotation. When the upper and lower brackets are closed, two circular hollow grooves are formed inside, and the circular hollow grooves are used to place liquid and gas cylinders.

[0042] The supporting assembly 3 includes an electric telescopic rod 301 fixed to the side of the lower bracket 101, and the output end of the electric telescopic rod 301 is movably hinged with a supporting plate 302. The electric telescopic rod 301 is used to control the up and down movement of the supporting plate 302, and is used to adjust the height position of the liquid supply gas cylinder in the upper and lower brackets.

[0043] The working principle of the industrial gas cylinder cart proposed in this embodiment is: when in use, with the upper and lower brackets in the unfolded state, the liquid supply gas cylinder is placed on the supporting plate 302, so that friction resistance is generated between the bottom of the bottle body and the rubber pad 303, and the gas cylinder is ensured to fit on the buffer plate 107 in the groove body of the lower bracket 101. At this time, the upper bracket 201 and the lower bracket 101 are closed, so that the magnetic plates 204 are adsorbed on each other to achieve preliminary fixation of the brackets, and then the fixing screw 109 is rotated so that the fixing screw 109 is threadedly connected to the first fixing plate 108 and the second fixing plate 203 to achieve complete fixation of the upper and lower brackets, and then the electric extension is controlled. The output end of the retracted rod 301 is retracted, so that the support plate 302 moves upward, and the gas cylinder placed inside is lifted to a random height. At the same time, the stabilizing sleeve 305 is inserted into the stabilizing sleeve 401 to limit the support plate 302 and prevent the support plate 302 from rotating. The stabilizing sleeve 305 is then fixed by rotating the locking screw 403. At the same time, the fixing screw 205 is rotated to make its front end close to the side of the gas cylinder to fix the gas cylinder. The device is then tilted as a whole by pulling the handle 103. By pulling the handle 103, the moving wheel 112 is rotated in contact with the ground, so that the device drives the gas cylinder to move.

[0044] Furthermore, a protective plate 104 is fixed in the lower bracket 101 , a mounting groove 105 is opened on the protective plate 104 , a buffer spring 106 is fixed in the mounting groove 105 , a buffer plate 107 is fixed at one end of the buffer spring 106 , and the side of the buffer plate 107 is consistent with the diameter of the protective plate 104 .

[0045] More specifically, the protective plate 104 is arc-shaped and matches the diameter of the groove in the lower bracket 101. When the gas cylinder is placed on the lower bracket, the side is attached to the buffer plate 107. The pressure generated at this time presses the buffer plate 107, which is tightened by the buffer spring 106 to achieve a buffering effect on the gas cylinder.

[0046] Furthermore, a first fixing plate 108 is fixed to the side of the lower bracket 101, and a second fixing plate 203 is fixed to the side of the upper bracket 201. Magnetic plates 204 are fixed inside the first and second fixing plates and are attracted to each other.

[0047] More specifically, the first fixing plates 108 are installed at both ends and the middle of the side of the lower bracket 101, and the second fixing plates 203 are installed at both ends and the middle of the side of the upper bracket 201. The first and second fixing plates correspond to each other, and magnetic plates 204 are installed inside the opposite surfaces. When the upper and lower brackets are closed, the magnetic plates 204 are adsorbed and fixed to each other, thereby achieving the effect of preliminary fixing of the upper and lower brackets.

[0048] Furthermore, the lower bracket 101 and the upper bracket 201 are internally threadedly connected with a fixing screw 109 .

[0049] More specifically, after the upper and lower brackets are closed, the fixing screw 109 is rotated clockwise so that the fixing screw 109 is threadedly connected to the first and second fixing plates, thereby completely fixing the two brackets. The fixing screw 109 is rotated counterclockwise so that either end is detached from the fixing plate, so that the upper and lower brackets can be unfolded, thereby achieving the effect of disassembling and assembling the gas cylinder.

[0050] Furthermore, a fixing screw 205 is threadedly connected to the side of the upper bracket 201 .

[0051] More specifically, by rotating the fixing screw 205 clockwise, its front end moves into the bracket and fits tightly against the side of the gas cylinder, thereby fixing gas cylinders of different diameters. After rotating it counterclockwise, its front end gradually moves backward and separates from the side of the gas cylinder. At this time, the height of the gas cylinder and the rotation of the bottle body can be adjusted.

[0052] Furthermore, a rubber pad 303 is fixed on the supporting plate 302 and corresponds to the upper and lower brackets.

[0053] More specifically, the rubber pad 303 has a certain elasticity, and after the top contacts the bottom of the gas cylinder, a concave phenomenon occurs, and friction resistance is generated between the contact surfaces to avoid shaking and improve the stability of the gas cylinder.

[0054] Furthermore, a connecting block 304 is fixed to the side of the supporting plate 302 , a stabilizing sleeve rod 305 is fixed to the connecting block 304 , and a stabilizing sleeve 401 is fixed to the sides of the upper and lower brackets, and the stabilizing sleeve rod 305 is movably sleeved in the stabilizing sleeve 401 .

[0055] More specifically, when the support plate 302 moves up and down, the stabilizing rod 305 is inserted into the stabilizing sleeve 401, so as to fix the support plate 302 in place and prevent it from rotating. After the stabilizing rod 305 is separated from the stabilizing sleeve 401, the support plate 302 can rotate. When the support plate 302 rotates, the bottom of the gas cylinder loses support, so that the gas cylinder can be unloaded.

[0056] Furthermore, a locking screw 403 is threadedly connected to the side of the stabilizing sleeve 401 , and one end of the locking screw 403 is attached to the side of the stabilizing sleeve rod 305 .

[0057] More specifically, when the locking screw 403 rotates clockwise or counterclockwise, the front end is detached from or pressed against the side of the stabilizing sleeve 305. When the front end is pressed against the side of the stabilizing sleeve 305, the stabilizing sleeve 305 is fixed in the stabilizing sleeve 401. After the front end is detached from the stabilizing sleeve 305, the stabilizing sleeve 305 can be detached from the stabilizing sleeve 401, thereby adjusting the height of the support plate 302.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
