Description

Technical Field

[0001] This utility model relates to the field of special gas cylinder transportation technology, specifically a safe handling device for special gas cylinders. Background Technology

[0002] Specialty gas cylinder safety handling devices are specialized equipment designed for the safe transfer and transportation of high-pressure, high-risk, or high-value gas cylinders. Common examples include cylinder trolleys and cylinder frames. These devices typically employ metal structures and are equipped with fastening straps or chains to reliably secure the cylinders. They also feature casters at the bottom for easy movement. Their core design purpose is to effectively prevent serious safety accidents such as leaks and explosions caused by tipping, collisions, or rolling of the cylinders during handling. They are key tools for achieving inherently safe management of gas cylinders.

[0003] A gas cylinder handling device disclosed in Chinese Patent Publication No. CN 212738210 U includes a vehicle body and a moving component. The moving component is connected to the vehicle body and can drive the vehicle body to move. The vehicle body is equipped with multiple gas cylinder mounting structures for mounting gas cylinders, enabling the convenient one-time handling of multiple gas cylinders without requiring the operator to handle them repeatedly, thus achieving high handling efficiency. Furthermore, the gas cylinder handling device also includes a weighing component mounted on the vehicle body. The weighing component is used to weigh the gas cylinders, allowing the operator to understand the remaining gas volume within each cylinder. The operator can then classify the gas cylinders based on the remaining gas volume for separate processing.

[0004] However, the use of gas cylinder handling devices has certain limitations. During the movement of gas cylinders, the force generated by bumps and shaking may cause collisions, resulting in gas leaks and other safety hazards, which cannot effectively guarantee the safety and stability of gas cylinder transportation. Utility Model Content

[0005] The purpose of this invention is to provide a safe handling device for special gas cylinders to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a safe handling device for special gas cylinders, including a movable base, a lifting mechanism at the top of the movable base, a support platform at the bottom of the lifting mechanism, insertion slots evenly spaced on the upper surface of the support platform, buffer mechanisms on the left and right sides of the support platform, and a pushing mechanism for pushing the support platform out of the movable base.

[0007] Preferably, a push handle is fixedly connected to the top of the rear end of the movable seat, and a controller is fixedly connected to the right side of the upper surface of the push handle.

[0008] Preferably, the lifting mechanism includes a first servo motor fixedly connected to the left side of the top of the movable seat, a first take-up roller mounted on the output shaft end of the first servo motor, a first sprocket coaxially fixedly connected to the right side of the first take-up roller, a chain meshing with the outside of the first sprocket, a second sprocket meshing with the inside of the rear end of the chain, a second take-up roller coaxially fixedly connected to the left side of the second sprocket, and pull ropes fixedly connected to the left and right sides of the outside of the first and second take-up rollers respectively, with the bottom ends of the four pull ropes fixedly connected to the perimeter of the upper surface of the support platform.

[0009] Preferably, the buffer mechanism includes through grooves opened opposite to each other on the bottom ends of the left and right sides of the support platform. A rubber sleeve is fixedly connected inside the through groove. Springs are evenly and longitudinally fixed inside the rubber sleeve at equal intervals. The rubber sleeve is filled with a damping medium. A limit plate is slidably connected to the outside of the through groove. A buffer plate is fixedly connected to the outside of the limit plate.

[0010] Preferably, the pushing mechanism includes a rack fixed to the bottom end of the lower surface of the buffer plate, a fixed seat fixed to the bottom end of the left and right sides inside the movable seat, a longitudinal groove is opened inside the top of the fixed seat, and a gear is uniformly and longitudinally rotatably connected to the bottom end of the longitudinal groove at equal distances. A second servo motor is fixed to the outer side of the front end of the fixed seat, and the gear at the front end of the longitudinal groove is installed on the output shaft end of the second servo motor.

[0011] Preferably, the lower surface of the rack and the upper surface of the gear are meshed when they come into contact.

[0012] Preferably, the insertion slot is cylindrical, with a hemispherical groove at the bottom inside the insertion slot, and a rubber pad is fixed to the contact surface between the insertion slot and the gas cylinder.

[0013] Preferably, a counterweight ball is fixedly attached to the center of the lower surface of the support platform.

[0014] Preferably, the movable seat is rotatably connected to the outer perimeter of the movable seat, and the movable wheels are provided with anti-slip grooves at equal intervals around their outer circumference.

[0015] Preferably, the pull rope is made of ultra-high molecular weight polyethylene.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This special gas cylinder safety handling device features multiple insertion slots on the platform for inserting special gas cylinders. Simultaneously, a first servo motor inside the moving seat drives a first winding roller to rotate. A first sprocket on one side of the first winding roller drives a second sprocket via a chain. At this time, a second winding roller on the side of the second sprocket simultaneously winds up the pull rope, suspending the platform and the internal special gas cylinders, thus preventing collisions during transport. Furthermore, buffer mechanisms are installed on both sides of the platform. When the platform sways and approaches the inner wall of the moving seat, the buffer plate on the platform first contacts the inner wall. The buffer plate then compresses the spring inside the rubber sleeve via a limiting plate. The reaction force of the compressed spring is buffered by the damping medium inside the rubber sleeve, effectively protecting the entire platform. Combined with a counterweight ball at the bottom of the platform, this reduces swaying caused by suspension, further improving the safety and stability of special gas cylinder transport. 2. This special gas cylinder safety handling device has a rack fixed to the bottom of the buffer plate. When the special gas cylinder is moved to the designated position and released by the pull rope on the lifting mechanism, the rack on the buffer plate on both sides of the platform moves downward and can be inserted into the longitudinal groove on the fixed seat, and mesh with the gear at the bottom of the longitudinal groove. At this time, the second servo motor drives the gear at the front end of the longitudinal groove to rotate, and the gear can push the platform to quickly extend from the inside of the moving seat through the rack, thereby quickly discharging the special gas cylinder and effectively improving the convenience of transporting and unloading the special gas cylinder.

[0020] 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.

[0021] like Figure 1-5 As shown, this utility model has the following two specific embodiments.

[0022] Example 1 A safety handling device for special gas cylinders includes a movable base 1, a lifting mechanism at the top of the movable base 1, a support platform 3 at the bottom of the lifting mechanism, insertion slots 301 evenly spaced on the upper surface of the support platform 3, buffer mechanisms on the left and right sides of the support platform 3, and a pushing mechanism.

[0023] A push handle 101 is fixedly connected to the top of the rear end of the movable seat 1, and a controller 102 is fixedly connected to the right side of the upper surface of the push handle 101. The controller 102 can control and start the internal electrical equipment of the movable seat 1.

[0024] The lifting mechanism includes a first servo motor 2 fixedly connected to the left side of the top of the movable base 1. A first take-up roller 201 is mounted on the output shaft end of the first servo motor 2. A first sprocket 202 is coaxially fixedly connected to the right side of the first take-up roller 201. A chain 203 is meshed with the outside of the first sprocket 202. A second sprocket 204 is meshed with the inside of the rear end of the chain 203. A second take-up roller 205 is coaxially fixedly connected to the left side of the second sprocket 204. Pull ropes 206 are fixedly connected to the left and right sides of the first take-up roller 201 and the second take-up roller 205 respectively. The bottom end of the rope 206 is fixed to the perimeter of the upper surface of the support platform 3. When the first servo motor 2 is started, it can drive the first take-up roller 201 to rotate. At this time, the first take-up roller 201 can drive the first sprocket 202 on one side to rotate. Simultaneously, the first sprocket 202 can drive the second sprocket 204 to rotate through the chain 203. Then, the second sprocket 204 can drive the second take-up roller 205 on one side to rotate synchronously. At this time, the second take-up roller 205 and the first take-up roller 201 can wind up the rope 206 and drive the support platform 3 to move up and down inside the movable seat 1.

[0025] The buffer mechanism includes through grooves 4 opened opposite each other on the bottom ends of the left and right sides of the support platform 3. A rubber sleeve 401 is fixed inside the through groove 4. Springs 402 are evenly and longitudinally fixed inside the rubber sleeve 401. The rubber sleeve 401 is filled with a damping medium. A limit plate 403 is slidably connected to the outside of the through groove 4. A buffer plate 404 is fixed to the outside of the limit plate 403. The buffer plate 404 contacts the inner wall of the movable seat 1 and is subjected to force. The springs 402 inside the rubber sleeve 401 can be squeezed by the limit plate 403. Due to the reaction force of the squeezed springs 402, the buffer plate 404 can be pushed back to its original position by the limit plate 403. At the same time, the damping medium inside the rubber sleeve 401 can convert the kinetic energy generated by the internal movement into heat energy for consumption, thereby effectively buffering the support platform 3.

[0026] The insertion slot 301 is cylindrical, and a hemispherical groove is provided at the bottom of the insertion slot 301. A rubber pad is fixed to the contact surface between the insertion slot 301 and the gas cylinder.

[0027] A counterweight ball 302 is fixed at the center of the lower surface of the support platform 3. The counterweight ball 302 can generate a counteracting force to reduce the overall sway of the support platform 3.

[0028] The movable seat 1 is rotatably connected to the four sides of the outside, and the movable wheels are provided with anti-slip grooves at equal intervals around the outside.

[0029] The pull rope 206 is made of ultra-high molecular weight polyethylene.

[0030] Example 2 The difference from Embodiment 1 is that this embodiment discloses a pushing mechanism for pushing the tray 3 out of the movable seat 1: The pushing mechanism includes a rack 405 fixed to the bottom of the lower surface of the buffer plate 404. Fixed seats 5 are fixed to the bottom of the left and right sides inside the movable seat 1. A longitudinal groove 501 is opened inside the top of the fixed seat 5. Gears 502 are evenly and longitudinally rotatably connected to the bottom of the longitudinal groove 501 at equal intervals. A second servo motor 503 is fixed to the outer side of the front end of the fixed seat 5. The output shaft end of the second servo motor 503 is equipped with the gear 502 at the front end of the longitudinal groove 501. When the rack 405 at the bottom of the rubber sleeve 401 is inserted into the longitudinal groove 501 on the fixed seat 5, the gear 502 can mesh with the rack 405 above. At this time, the second servo motor 503 is started to drive the gear 502 to rotate. The gear 502 can push the rack 405 at the bottom of the buffer plate 404 and push the entire support table 3 to move.

[0031] When the lower surface of the rack 405 contacts the upper surface of the gear 502, they mesh with each other. All contents not described in detail in this specification are prior art known to those skilled in the art.

[0032] In this embodiment of the application, when in use: the second servo motor 503 inside the fixed base 5 starts, which drives the gear 502 to rotate. At this time, the gear 502 pushes the rack 405 on the buffer plate 404, which causes the buffer plate 404 to drive the platform 3 to extend out from the inside of the movable base 1. At this time, the special gas cylinder to be transported can be inserted into the insertion slot 301 on the platform 3. The second servo motor 503 drives the gear 502 to reverse, which pushes the platform 3 into the inside of the movable base 1. At this time, the first servo motor 2 inside the movable base 1 starts, which drives the first take-up roller 201 to rotate. At this time, the first take-up roller 201 drives the first sprocket 202 on one side to rotate. At the same time, the first sprocket 202 drives the second sprocket 204 to rotate through the chain 203. 4 can drive the second take-up roller 205 on one side to rotate synchronously. At this time, the second take-up roller 205 and the first take-up roller 201 can wind up the rope 206 and drive the support platform 3 to be lifted, so that the support platform 3 can carry the special gas cylinder to be suspended. At this time, the controller 102 can push the entire conveying device to move. The support platform 3 is provided with buffer plates 404 on both sides. When the buffer plate 404 contacts the inner wall of the moving seat 1 and is subjected to force, the spring 402 in the rubber sleeve 401 can be squeezed by the limiting plate 403. Due to the reaction force of the spring 402 being squeezed, the buffer plate 404 can be pushed to reset by the limiting plate 403. At the same time, the damping medium in the rubber sleeve 401 can convert the kinetic energy generated by the internal movement into heat energy for consumption, thereby effectively buffering the support platform 3.

[0033] In some embodiments, the special gas cylinder safety handling device can be combined with at least one robotic arm to handle the cylinder, thereby forming a special gas cylinder safety handling system.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
