Description

Technical Field

[0001] This invention belongs to the field of gas cylinder handling technology, specifically relating to a gas cylinder handling device based on steel structure construction. Background Technology

[0002] Gas cylinders are essential but high-risk equipment in steel structure construction, requiring standardized management and strict operation. While modern projects tend to use safer and more efficient methods such as centralized gas supply, gas cylinders still offer irreplaceable advantages in flexibility and mobility. Safe use of gas cylinders is crucial for ensuring the smooth progress of steel structure construction. However, when using gas cylinders in steel structure construction, convenient transportation is essential, and gas cylinder handling devices can make construction safer and more efficient. These devices typically employ a metal frame structure with a stable base and convenient moving parts (such as casters). Their core function is to achieve rapid gripping, smooth lifting, flexible movement, and precise positioning of gas cylinders through mechanical or hydraulic means. Common types include trolley-type, forklift-attached type, and fully automated handling robots. Their main purpose is to significantly reduce the labor intensity and risk of workplace injuries (such as crushing injuries and sprains) for operators, effectively preventing valve damage or gas leaks caused by tipping or collisions during transport, thereby ensuring personnel safety and equipment integrity. Meanwhile, it can significantly improve the efficiency of gas cylinder movement between warehouses, workshops, and usage points, making it an important tool for achieving standardized and safe logistics management on the production site. In short, gas cylinder handling equipment is an indispensable auxiliary device in modern industry, ensuring the safety, labor-saving, and high efficiency of gas cylinder handling operations through mechanization.

[0003] Currently, gas cylinders are typically moved using handcarts. However, these handcarts lack sun protection. Since the cylinders contain high-pressure or liquefied gases, prolonged exposure to direct sunlight can cause the internal pressure to exceed the cylinder's maximum pressure limit, leading to a powerful physical explosion that threatens the lives of workers. Furthermore, existing cylinder handling devices simply secure the cylinders to the handcart, leaving a large area of ​​the cylinder's outer surface exposed to the elements. Violent impacts can cause cracks, dents, or scratches on the cylinder, increasing the risk of explosion and further endangering workers' lives. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a gas cylinder handling device based on steel structure construction.

[0005] The technical solution adopted to solve the above technical problems is: a gas cylinder handling device based on steel structure construction, including a moving mechanism, a lifting mechanism installed on the top of the moving mechanism, and a sun protection mechanism installed on the lifting mechanism; The sun protection mechanism has two clamping mechanisms installed at its internal center and a protective mechanism installed at its top. The two clamping mechanisms are used to clamp and fix the gas cylinder.

[0006] Furthermore, the moving mechanism includes a frame, with wheels mounted on one side of the front and rear ends of the frame, two omnidirectional wheels mounted on the other side of the bottom of the frame, a pedal fixedly connected to the other side of the top of the frame, a support frame rotatably connected to one side of the frame, a limit frame fixedly connected to the top side of the support frame, two limit rods fixedly connected to the center of the limit frame, handrails fixedly connected to the top of the front and rear ends of the limit frame, a connecting frame fixedly connected to the center of one side of the limit frame, and a stop frame fixedly connected to the center of the top of the frame.

[0007] With the above technical solution, when moving gas cylinders, after the gas cylinder is clamped by the clamping mechanism, the worker steps on the pedal and rotates the limiting frame by a certain angle through the handrail, so that one side of the support frame is in contact with the stop frame, thereby supporting the gas cylinder on the support frame. The handrail is at an inclined angle, which facilitates the worker's subsequent pushing. When moving the gas cylinder, the worker pushes the handrail and moves the gas cylinder through the two wheels and casters, which saves time and effort. When loading and unloading the gas cylinder, the moving mechanism needs to be stable and stationary. The movement of the moving mechanism is locked by the two casters, and then the handrail is pushed to rotate the limiting frame, so that the bottom of the support frame contacts the ground, making the whole thing vertical, which facilitates the loading and unloading of the gas cylinder.

[0008] Furthermore, the lifting mechanism includes a lifting frame, with bases fixedly connected to the four bottom corners of the lifting frame. Two sliders are fixedly connected to one side of the front and rear ends of the lifting frame. A hydraulic rod is fixedly installed at the center of the top side of the support frame. A rotating shaft is fixedly connected to the top of the piston of the hydraulic rod. Sprockets are rotatably connected to the front and rear ends of the outer wall of the rotating shaft. Chains are meshed on both sprockets.

[0009] With the above technical solution, when it is necessary to lift and move the gas cylinder, the hydraulic rod is activated, and the piston pushes the rotating shaft, which in turn pushes the two sprockets. Since the two sprockets are engaged with the corresponding chains, they will roll on the corresponding chains as they move upward, thereby slowly lifting the lifting frame. This allows the gas cylinder to be lifted and moved to the designated height, facilitating subsequent handling by the staff.

[0010] Furthermore, the multiple sliders are slidably connected to their corresponding limiting rods, one end of each of the two chains is fixedly connected to the lifting frame, and the other end of each of the two chains is fixedly connected to the connecting frame.

[0011] Through the above technical solution, the lifting frame can be slidably connected to the corresponding limit rods through multiple sliders during the lifting process, so as to prevent the gas cylinder from tilting during the lifting process and improve the stability of gas cylinder handling.

[0012] Furthermore, the sun protection mechanism includes an outer shell fixedly connected to the center of the top of the lifting frame, an inner shell rotatably connected to the inner wall of the outer shell, a gear ring fixedly connected to the bottom end of the outer wall of the inner shell, a motor fixedly installed on the top of the lifting frame, a gear fixedly connected to the outer wall of the motor output shaft, and a plurality of annularly distributed first springs fixedly connected to the inner wall of the inner shell. The inner ends of the plurality of first springs are all fixedly connected to mounting brackets, and pulleys are installed on the plurality of mounting brackets.

[0013] Through the above technical solution, when handling gas cylinders, the outer protective shell can provide physical protection to prevent hard objects from directly impacting the gas cylinder. The inner protective shell also has a protective effect and a certain degree of anti-smashing effect. At the same time, the combination of the outer and inner protective shells can provide sun protection, preventing high-temperature sunlight from directly hitting the gas cylinder, thereby preventing the gas pressure inside the gas cylinder from increasing and reducing the factors of explosion.

[0014] Furthermore, the gear meshes with the gear ring, and the elastic force of the multiple first springs is much greater than the weight of the corresponding pulleys themselves.

[0015] With the above technical solution, before handling the gas cylinder, the openings of the outer and inner protective shells are in the same position, facilitating the handling of the gas cylinder inside the inner protective shell. After clamping and fixing the gas cylinder, to improve the sun protection and impact resistance, the motor is started. The output shaft rotates, driving the gear to rotate, which in turn drives the gear ring to rotate, thus rotating the inner protective shell 180 degrees. This makes the opening of the inner protective shell face the inner wall of the outer protective shell, allowing both the outer and inner protective shells to completely cover the gas cylinder, preventing sunlight from entering. When the inner protective shell is impacted, the impact force is buffered by the first spring at the corresponding position, preventing the inner protective shell from denting too deeply and impacting the gas cylinder. Multiple pulleys facilitate quick contact with the outer surface of the gas cylinder during installation, allowing the first spring to stably buffer the impact force on the inner protective shell.

[0016] Furthermore, the clamping mechanism includes a fixed plate fixedly connected to one side of the inner wall of the inner shell. Two fixed frames are fixedly connected to the inner side of the fixed plate. An L-shaped rod is rotatably connected to the center of each of the two fixed frames. A first clamping wheel is installed at one end of each of the two L-shaped rods. Fixed seats are fixedly connected to the front and rear ends of one side of the fixed plate. A cylinder is rotatably connected to each of the two fixed seats. A second clamping wheel is installed on the inner side of each of the two fixed frames.

[0017] With the above technical solution, when installing the gas cylinder, the worker places the gas cylinder inside the inner protective shell and into contact with the two second clamping wheels. At this time, the two cylinders are activated, and the piston pushes the L-shaped rod, thereby driving the two first clamping wheels to rotate, so that the two first clamping wheels clamp the outer wall of the gas cylinder, thus achieving clamping.

[0018] Furthermore, one end of each of the two cylinder pistons is rotatably connected to a corresponding L-shaped rod.

[0019] Through the above technical solution, the two first clamping wheels and the two second clamping wheels can quickly clamp the gas cylinder and have a good clamping effect, preventing the gas cylinder from shifting or shaking during transportation and improving the protection effect of the gas cylinder.

[0020] Furthermore, the protective mechanism includes an electric telescopic rod fixedly installed at the top center of the outer shell. A top plate is fixedly connected to the bottom end of the piston of the electric telescopic rod. A plurality of second springs are fixedly connected to the bottom of the top plate. A buffer plate is fixedly connected between the bottom ends of the plurality of second springs. A plurality of guide rods are fixedly connected to the top of the buffer plate. A protective cover is fixedly connected to the bottom center of the buffer plate. A rubber ring is fixedly connected to the bottom of the protective cover.

[0021] With the above technical solution, after the gas cylinder is clamped and fixed, the electric telescopic rod is activated. The piston pushes the top plate, causing the top plate to contact the top of the inner shell. The top plate moves downward, causing the protective cover and rubber ring to move, so that the rubber ring contacts the outer surface of the gas cylinder. At the same time, the protective cover covers the valve of the gas cylinder, preventing external objects from directly impacting the valve and causing it to open, resulting in gas leakage and impact. This greatly improves the protection of the gas cylinder valve, thereby reducing the factors that may cause gas cylinder failure.

[0022] Furthermore, the tops of the multiple guide rods all penetrate the top plate and the outer casing.

[0023] With the above technical solution, when the gas cylinder is shaken during transportation, the protective cover uses multiple second springs to buffer the force of the shaking, preventing the protective cover from making hard contact with the gas cylinder through the electric telescopic rod, thus giving the protective cover a buffering effect.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention designs a sun protection mechanism, through which the outer shell can provide physical protection to the outer shell, preventing hard objects from directly impacting the gas cylinder. The inner shell also has a protective effect and a certain anti-smashing effect. At the same time, the combination of the outer shell and the inner shell can provide sun protection, preventing the high temperature sun from directly irradiating the gas cylinder, thereby preventing the gas pressure inside the gas cylinder from increasing and reducing the factors of explosion; (2) The present invention designs a protective mechanism, through which the protective cover covers the valve of the gas cylinder, preventing external objects from directly impacting the valve, causing the valve to open, causing the gas cylinder to leak and impact, greatly improving the protection of the gas cylinder valve, thereby reducing the factors of gas cylinder failure; (3) The present invention designs a lifting mechanism, through the cooperation of two sprockets and chains, which can drive the gas cylinder to lift to a specified height, making it convenient for staff to move it later.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] like Figures 1-4As shown, this embodiment of a gas cylinder handling device based on steel structure construction includes a moving mechanism 1. The moving mechanism 1 includes a frame 101. Wheels 102 are installed on one side of the front and rear ends of the frame 101. Two casters 103 are installed on the other side of the bottom of the frame 101. A pedal 104 is fixedly connected to the other side of the top of the frame 101. A support frame 105 is rotatably connected to one side of the frame 101. A limit frame 106 is fixedly connected to the top of the support frame 105. Two limit rods 107 are fixedly connected to the center of the limit frame 106. Handrails 108 are fixedly connected to the top of the front and rear ends of the limit frame 106. A connecting frame 109 is fixedly connected to the center of one side of the limit frame 106. A stop frame 110 is fixedly connected to the center of the top of the frame 101. When handling gas cylinders 6, the device moves by... After the clamping mechanism 4 clamps the gas cylinder 6, the worker steps on the pedal 104 and rotates the limiting frame 106 by a certain angle through the handrail 108, so that one side of the support frame 105 is in contact with the stop frame 110, thereby supporting the gas cylinder 6 on the support frame 105. This makes the handrail 108 tilted at an angle, which is convenient for the worker to push it later. When the worker moves the gas cylinder 6, he pushes the handrail 108 and moves the gas cylinder 6 through the two wheels 102 and the casters 103, which saves time and effort. When loading and unloading the gas cylinder 6, the moving mechanism 1 needs to be stable and stationary. The movement of the moving mechanism 1 is locked by the two casters 103. Then, the handrail 108 is pushed to rotate the limiting frame 106, so that the bottom of the support frame 105 contacts the ground, making the whole thing vertical, which is convenient for loading and unloading the gas cylinder 6.

[0029] like Figures 1-4As shown, a lifting mechanism 2 is installed on the top of the moving mechanism 1. The lifting mechanism 2 includes a lifting frame 201. Bases 202 are fixedly connected to the four corners of the bottom of the lifting frame 201. Two sliders 203 are fixedly connected to one side of the front and rear ends of the lifting frame 201. A hydraulic rod 204 is fixedly installed at the center of the top side of the support frame 105. A rotating shaft 205 is fixedly connected to the top of the piston of the hydraulic rod 204. Sprockets 206 are rotatably connected to the front and rear ends of the outer wall of the rotating shaft 205. Chains 207 are meshed on both sprockets 206. When the gas cylinder 6 needs to be lifted and moved, the hydraulic rod 204 is activated, pushing the rotating shaft 205 through the piston, thereby pushing the two sprockets 206. Since the two sprockets 206 are meshed with the corresponding chains 207... When the two sprockets 206 are engaged, they will roll on the corresponding chains 207 as they move upward, thus slowly lifting the lifting frame 201. This allows for the lifting and transport of the gas cylinder 6 to a designated height, facilitating subsequent handling by staff. Multiple sliders 203 are slidably connected to the corresponding limit rods 107. One end of each of the two chains 207 is fixedly connected to the lifting frame 201, and the other end of each chain 207 is fixedly connected to the connecting frame 109. During the lifting process, the lifting frame 201 can be stably lifted and lowered by the sliding connection between the multiple sliders 203 and the corresponding limit rods 107, preventing the gas cylinder 6 from tilting during the lifting process and improving the stability of the handling of the gas cylinder 6.

[0030] like Figures 1-8As shown, a sunshade mechanism 3 is installed on the lifting mechanism 2. The sunshade mechanism 3 includes an outer shell 301 fixedly connected to the center of the top of the lifting frame 201, an inner shell 302 rotatably connected to the inner wall of the outer shell 301, a gear ring 303 fixedly connected to the bottom end of the outer wall of the inner shell 302, a motor 304 fixedly installed on the top of the lifting frame 201, a gear 305 fixedly connected to the outer wall of the output shaft of the motor 304, and a plurality of annularly distributed first springs 306 fixedly connected to the inner wall of the inner shell 302. Each inner end is fixedly connected to a mounting bracket 307, and multiple mounting brackets 307 are equipped with pulleys 308. When moving the gas cylinder 6, the outer protective shell 301 can provide physical protection to prevent hard objects from directly impacting the gas cylinder 6. The inner protective shell 302 also has a protective effect, providing a certain degree of anti-smashing effect. At the same time, the combination of the outer protective shell 301 and the inner protective shell 302 can provide sun protection, preventing high-temperature sunlight from directly hitting the gas cylinder 6, thereby preventing the gas pressure inside the gas cylinder 6 from increasing and reducing the factors of explosion. Gear 305 and gear ring... 303 engages, and the elastic force of multiple first springs 306 is far greater than the weight of the corresponding pulleys 308. Before moving the gas cylinder 6, the openings of the outer shell 301 and the inner shell 302 are in the same position, facilitating the movement of the gas cylinder 6 into the inner shell 302. After clamping and securing the gas cylinder 6, to improve its sun protection and impact resistance, the motor 304 is started. The output shaft rotates, driving the gear 305 to rotate, which in turn drives the gear ring 303 to rotate, thereby causing the inner shell 302 to rotate 180 degrees. The opening faces the inner wall of the outer shell 301, so that the outer shell 301 and the inner shell 302 completely cover the gas cylinder 6, thereby preventing sunlight from shining in. When the inner shell 302 is impacted, the impact force is buffered by the first spring 306 at the corresponding position, preventing the inner shell 302 from being dented too deeply and thus impacting the gas cylinder 6. The multiple pulleys 308 facilitate the quick contact with the outer surface of the gas cylinder 6 when installing it, so that the first spring 306 can stably buffer the impact force on the inner shell 302.

[0031] like Figures 1-7As shown, two clamping mechanisms 4 are installed at the center of the sun protection mechanism 3. Each clamping mechanism 4 includes a fixed plate 401 fixedly connected to one side of the inner wall of the inner shell 302. Two fixed brackets 402 are fixedly connected to the inner side of the fixed plate 401. An L-shaped rod 403 is rotatably connected to the center of each of the two fixed brackets 402. A first clamping wheel 404 is installed at one end of each of the two L-shaped rods 403. Fixed seats 405 are fixedly connected to the front and rear ends of one side of the fixed plate 401. A cylinder 406 is rotatably connected to each of the two fixed seats 405. A second clamping wheel 407 is installed on the inner side of each of the two fixed brackets 402. When installing the gas cylinder 6... The staff places the gas cylinder 6 inside the inner protective shell 302, making it contact with the two second clamping wheels 407. At this time, the two cylinders 406 are activated, and the pistons push the L-shaped rods 403, thereby driving the two first clamping wheels 404 to rotate, so that the two first clamping wheels 404 clamp the outer wall of the gas cylinder 6, achieving clamping. One end of the piston of the two cylinders 406 is rotatably connected to the corresponding L-shaped rods 403. The two first clamping wheels 404 and the two second clamping wheels 407 can quickly clamp the gas cylinder 6, and the clamping effect is good, preventing the gas cylinder 6 from shifting or shaking during transportation, thus improving the protection effect of the gas cylinder 6.

[0032] like Figures 1-9 As shown, a protective mechanism 5 is installed at the top of the sun protection mechanism 3. Two clamping mechanisms 4 are used to clamp and fix the gas cylinder 6. The protective mechanism 5 includes an electric telescopic rod 501 fixedly installed at the center of the top of the outer shell 301. A top plate 502 is fixedly connected to the bottom end of the piston of the electric telescopic rod 501. Multiple second springs 503 are fixedly connected to the bottom of the top plate 502. A buffer plate 504 is fixedly connected between the bottom ends of the multiple second springs 503. Multiple guide rods 505 are fixedly connected to the top of the buffer plate 504. A protective cover 506 is fixedly connected to the center of the bottom of the buffer plate 504. A rubber ring 507 is fixedly connected to the bottom of the protective cover 506. After the gas cylinder 6 is clamped and fixed, the electric telescopic rod 501 is activated, which pushes the top plate 502 through the piston, causing the top plate 502 to open. The top of the top plate 502 contacts the top of the inner shell 302. The top plate 502 moves downward, causing the protective cover 506 and the rubber ring 507 to move, so that the rubber ring 507 contacts the outer surface of the gas cylinder 6. At the same time, the protective cover 506 covers the valve of the gas cylinder 6 to prevent external objects from directly impacting the valve, causing the valve to open and the gas cylinder 6 to leak gas. This greatly improves the protection of the valve of the gas cylinder 6, thereby reducing the factors that may cause the gas cylinder 6 to fail. The tops of multiple guide rods 505 all penetrate the top plate 502 and the outer shell 301. When the gas cylinder 6 shakes during transportation, the protective cover 506 buffers the force of the shaking through multiple second springs 503, preventing the protective cover 506 from making hard contact with the gas cylinder 6 through the electric telescopic rod 501, so that the protective cover 506 has a buffering effect.

[0033] The working principle of this embodiment is as follows: When installing the gas cylinder 6, the operator places the gas cylinder 6 inside the inner protective shell 302 and into contact with the two second clamping wheels 407. At this time, the two cylinders 406 are activated, and the piston pushes the L-shaped rod 403, thereby driving the two first clamping wheels 404 to rotate, so that the two first clamping wheels 404 clamp the outer wall of the gas cylinder 6 to achieve clamping. The motor 304 is activated, and the output shaft rotates to drive the gear 305 to rotate, thereby driving the gear ring 303 to rotate, thereby driving the inner protective shell 302 to rotate 180 degrees, so that the opening of the inner protective shell 302 faces the inner wall of the outer protective shell 301, so that the outer protective shell 301 and the inner protective shell 302 completely cover the gas cylinder 6, thereby preventing sunlight from shining in. Restart the electric telescopic rod 501, and push the top plate 502 through the piston, so that the top plate 502 contacts the top of the inner protective shell 302. The top plate 502 moves downward, driving the protective cover 506 and the rubber ring 507 to move, so that the rubber ring 507 contacts the outer surface of the gas cylinder 6. At the same time, the protective cover 506 covers the valve of the gas cylinder 6 to prevent external objects from directly hitting the valve. After the gas cylinder 6 is clamped and fixed, the worker steps on the pedal 104 and rotates the limiting frame 106 by a certain angle through the handrail 108, so that one side of the support frame 105 is in contact with the stop frame 110, thereby supporting the gas cylinder 6 on the support frame 105. The handrail 108 is at an inclined angle, which facilitates the worker's subsequent pushing. When the worker moves the gas cylinder 6, he pushes the handrail 108 and moves the gas cylinder 6 through the two wheels 102 and the caster 103. When it is moved to different heights, the hydraulic rod 204 is activated, which pushes the rotating shaft 205 through the piston, thereby pushing the two sprockets 206. Since the two sprockets 206 are engaged with the corresponding chains 207, the two sprockets 206 will roll on the corresponding chains 207 as they move upward, thereby slowly lifting the lifting frame 201, thus lifting and moving the gas cylinder 6.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
