Description

Technical Field

[0001] This utility model relates to the field of gas cylinder transportation technology, specifically a gas cylinder trolley. Background Technology

[0002] In the construction, industrial and other related production processes, gas cylinders are often used for welding and other operations. During the use of gas cylinders, trolleys are usually used for transportation and movement.

[0003] Current trolleys typically have a rotating arc-shaped cover or chain installed at the pocket position to cover and clamp the gas cylinder. While this method effectively restricts and secures the gas cylinder, vibrations during actual transportation can cause the cylinder to shake on the trolley, leading to rigid impacts that can affect the cylinder and the gas inside. Furthermore, installation requires additional adjustment and control of the cover and chain, making the cylinder installation process cumbersome. Therefore, this utility model provides a gas cylinder trolley to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a gas cylinder cart to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A gas cylinder trolley includes a base plate, with side rods fixedly installed on both sides of the top rear end of the base plate. A handle is installed at the end of the side rods away from the base plate. A pocket plate is fixedly installed at intervals between two adjacent sets of side rods. A drive wheel is installed at the bottom of each set of side rods, and a driven wheel is installed above the drive wheel. The side rods are hollow inside. A trigger assembly is installed at the bottom of the base plate. Clamping members are installed at both ends of the pocket plates. The trigger assembly and the clamping members are interconnected through the side rods.

[0006] As a further embodiment of this utility model, the triggering component includes a lifting groove, which is located at the top of the base plate corresponding to the inner ring of the pocket plate. An air box is fixedly installed at the bottom of the base plate, and the lifting groove passes through the base plate and communicates with the inside of the air box. A pressure plate is provided inside the lifting groove, and a sealing plate is fixedly installed at the bottom of the pressure plate. The end of the sealing plate away from the pressure plate is fixedly installed on the inner wall of the air box. A return spring is fixedly installed at intervals on the bottom inner side of the air box, and the end of the return spring away from the air box is fixedly installed on the bottom wall of the pressure plate.

[0007] As a further embodiment of this utility model, the bottom of the base plate is fixedly installed with support feet at intervals, and two sets of support feet and two sets of side rods correspond to each other. The inside of the support feet is hollow, and the inside of the support feet and the side rods are interconnected. A transmission pipe is fixedly installed on the side of the support feet near the air box. The inside of the transmission pipe is interconnected with the support feet and the air box, and the sealing plate is located above the transmission pipe.

[0008] As a further embodiment of this utility model, the clamping member includes a side clamping strip, which is an arc-shaped rubber bladder. The side clamping strip is fixedly installed on the side walls at both ends of the pocket plate, and the interior of the side clamping strip penetrates the pocket plate and communicates with the interior of the side rod. The inner diameter of the side clamping strip is adapted to the inner diameter of the pocket plate.

[0009] As a further embodiment of this utility model, a fixed shaft is fixedly installed on the inner side of the pocket plate corresponding to the position of the side clamping strip. A movable cylinder is fitted on the fixed shaft. A reset torsion spring is provided on the inner side of the movable cylinder. The movable cylinder and the fixed shaft are movably connected to each other through the reset torsion spring. An adjustment plate is fixedly installed at an angle on the side wall of the movable cylinder corresponding to the inner side of the side clamping strip away from the axis of the pocket plate. The end of the adjustment plate away from the movable cylinder is in contact with the inner outer wall of the side clamping strip.

[0010] As a further embodiment of this utility model, a guide groove is provided on the outer wall of the side clamping strip at the end of the adjusting plate away from the movable cylinder. The guide groove is an arc-shaped groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. When using the device of this utility model, the gas cylinder is placed on the pressure plate, and the pressure plate is adjusted accordingly. This allows the airflow in the gas box to be transmitted to the side clamping strip through the side rod, so that the side clamping strip can be compressed and expanded to clamp the two sides of the gas cylinder. During transportation, when the gas cylinder moves, it will move synchronously with the side clamping strip, which can effectively avoid the impact of rigid contact on the gas cylinder and the gas inside the gas cylinder. Moreover, during installation, only the gas cylinder needs to be placed, and the gas cylinder can be clamped and restricted by the trigger component and the clamping component.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 In this embodiment of the utility model, a gas cylinder trolley includes a base plate 1. Side rods 2 are fixedly installed on both sides of the top rear end of the base plate 1. The side rods 2 are "L"-shaped rods. A handrail is installed at the end of the side rods 2 away from the base plate 1. A pocket plate 3 is fixedly installed at intervals between two adjacent sets of side rods 2. The pocket plate 3 is an arc-shaped plate. The arc size of the pocket plate 3 is adapted to the outer diameter of the gas cylinder. A drive wheel 4 is installed at the bottom of both sets of side rods 2. A driven wheel 5 is installed above the drive wheel 4. The length of the driven wheel 5 from the side rod 2 is greater than the length of the drive wheel 4 from the side rod 2. The inside of the side rod 2 is hollow. A triggering component is installed at the bottom of the base plate 1. Clamping components are installed at both ends of the pocket plate 3. The triggering component and the clamping components are interconnected through the side rods 2.

[0020] When both the driving wheel 4 and the driven wheel 5 are in contact with the ground, the side rod 2 drives the pocket plate 3 to be in an inclined state. At this time, the gas cylinder can be placed on the pocket plate 3 that is spaced apart between two adjacent sets of side rods 2. At this time, by holding the side rod 2 and lifting it, the driven wheel 5 is separated from the ground, thereby enabling the gas cylinder to move.

[0021] When encountering a step, pressing down on the side rod 2 causes the driven wheel 5 to contact the ground. Using the driven wheel 5 as a fulcrum, the rod is pressed down further, causing the driving wheel 4 to rise. This pushes the side rod 2, allowing the driving wheel 4 to cross the step. Then, the side rod 2 is raised again, causing the driving wheel 4 to contact the ground. The driven wheel 5 separates from the ground and pushes the side rod 2, thus completing the movement to overcome the obstacle.

[0022] By placing the gas cylinder on the base plate 1, the pressure of the gas cylinder will act on the triggering component, causing the triggering component to start and transmit the airflow pressure to the clamping component, so that the clamping component is pressed to clamp the two sides of the gas cylinder.

[0023] The triggering component includes a lifting groove 8, which is located at the top of the base plate 1 corresponding to the inner ring of the pocket plate 3. An air box 10 is fixedly installed at the bottom of the base plate 1, and the lifting groove 8 penetrates the base plate 1 and communicates with the interior of the air box 10. A pressure plate 9 is provided inside the lifting groove 8, and a sealing plate 11 is fixedly installed at the bottom of the pressure plate 9. The sealing plate 11 is an arc-shaped soft rubber plate that can be deformed and adjusted. The end of the sealing plate 11 away from the pressure plate 9 is fixedly installed on the inner wall of the air box 10. Reset springs are fixedly installed at intervals on the bottom inner side of the air box 10. Spring 12, the return spring 12 is fixedly installed on the bottom wall of the pressure plate 9 at the end away from the air box 10. Support feet 6 are fixedly installed at intervals on the bottom of the base plate 1, and two sets of support feet 6 and two sets of side rods 2 correspond to each other. The inside of the support feet 6 is hollow, and the inside of the support feet 6 and the side rods 2 are interconnected. A conduction tube 13 is fixedly installed on the side of the support feet 6 near the air box 10. The conduction tube 13 is rectangular and the inside of the conduction tube 13 is interconnected with the support feet 6 and the air box 10 respectively. The sealing plate 11 is located above the conduction tube 13.

[0024] The gas cylinder is placed on the pressure plate 9. The pressure of the gas cylinder causes the pressure plate 9 to move downward, which in turn causes the sealing plate 11 to move downward. This causes the airflow inside the gas box 10 to be pressurized and transmitted to the support leg 6 through the transmission pipe 13. The airflow is then transmitted to the clamping member through the side rod 2, so that the clamping member clamps both sides of the gas cylinder.

[0025] A support block is fixedly installed in the middle of the inner side of the gas box 10. The support block prevents the pressure plate 9 from moving excessively downward due to the pressure of the gas cylinder, and effectively protects the return spring 12.

[0026] The clamping component includes a side clamping strip 7, which is an arc-shaped rubber bladder. The side clamping strip 7 can expand under pressure. The side clamping strip 7 is fixedly installed on the two side walls of the pocket plate 3. The interior of the side clamping strip 7 penetrates the pocket plate 3 and communicates with the interior of the side rod 2. The inner diameter of the side clamping strip 7 is adapted to the inner diameter of the pocket plate 3.

[0027] High-pressure airflow is transmitted to the inside of the side clamping strip 7, causing the side clamping strip 7 to expand under pressure. The expanded side clamping strip 7 will fit tightly with the gas cylinder, effectively clamping both sides of the gas cylinder according to the pressure, making the gas cylinder less likely to move during movement.

[0028] The deformable side clamps 7 allow the gas cylinder to move slightly during movement. The expandable side clamps 7 also prevent rigid collisions during movement, effectively protecting the gas cylinder and the gas inside and preventing accidents.

[0029] A fixed shaft 15 is fixedly installed on the inner side of the pocket plate 3 corresponding to the position of the side clamping strip 7. A movable cylinder 14 is fitted on the fixed shaft 15. A reset torsion spring 16 is provided on the inner side of the movable cylinder 14. The movable cylinder 14 and the fixed shaft 15 are movably connected to each other through the reset torsion spring 16. An adjustment plate 17 is fixedly installed at an angle on the side wall of the movable cylinder 14 corresponding to the inner side of the side clamping strip 7 away from the axis of the pocket plate 3. The end of the adjustment plate 17 away from the movable cylinder 14 is in contact with the inner outer wall of the side clamping strip 7.

[0030] In the initial state, the movable cylinder 14 will drive the adjusting plate 17 to rotate through the torque of the reset torsion spring 16. The rotation pressure can drive the side clamping strip 7 to move away from the axis of the pocket plate 3. At this time, the gas cylinder can be placed on the pocket plate 3 conveniently and quickly without the need for additional adjustment of the side clamping strip 7. After the gas cylinder is placed, the air pressure transmission will cause the air pressure inside the side rod 2 to push the adjusting plate 17, causing the adjusting plate 17 to rotate through the movable cylinder 14. At this time, the airflow will be transmitted to and filled inside the side clamping strip 7, causing the side clamping strip 7 to expand and fit together with the gas cylinder.

[0031] A guide groove 18 is provided on the outer wall of the side clamping strip 7 at the end of the adjusting plate 17 away from the movable cylinder 14. The guide groove 18 is an arc-shaped groove.

[0032] The guide groove 18 allows the airflow inside the side clamp 7 to flow back through the side rod 2 after the adjustment plate 17 is reset, thus avoiding the situation where the side clamp 7 is inconvenient to adjust after expansion.

[0033] An inflation valve can be installed at the end of the side rod 2 away from the base plate 1. The inflation valve can be used to inflate the side rod 2 to a specified pressure, which will significantly improve the clamping strength of the corresponding side clamping strip 7 after the gas cylinder is placed. The specific pressure can be set according to actual needs. At the same time, the inflation valve can also be used to replenish the air inside the side rod 2 to prevent insufficient air pressure inside the side rod 2 from reducing the clamping effect of the side clamping strip 7.

[0034] The working principle of this utility model is as follows: When using this invention, the inflation valve on the side rod 2 is inflated as needed to bring the air pressure inside the triggering component to an appropriate state. At this time, the gas cylinder is placed on the base plate 1, with the bottom of the gas cylinder corresponding to the pressure plate 9. The gas cylinder rests against the inner ring of the multiple sets of pocket plates 3. The pressure of the gas cylinder causes the pressure plate 9 to press down, causing the airflow inside the gas box 10 to be transmitted to the inside of the side clamping strip 7 through the side rod 2. This causes the side clamping strip 7 to expand under pressure and clamp the sides of the gas cylinder. When the gas cylinder is moved to a designated position and needs to be used directly, the device and the gas cylinder port are connected for direct use. At this time, the gas cylinder will be tilted and supported by the driving wheel 4 and the driven wheel 5. When it needs to be moved, the gas cylinder is pulled to separate the gas cylinder from the pressure plate 9. At this time, the pressure plate 9 will be reset by the return spring 12. The airflow pressure inside the side clamping strip 7 flows back to the gas box 10 through the side rod 2, and the side clamping strip 7 will become relaxed, thus enabling the gas cylinder to be moved out effectively and quickly.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
