Description

Technical Field

[0001] The utility model relates to the technical field of oxygen cutting operation equipment, in particular to a telescopic oxygen and propane cylinder trolley. Background Art

[0002] Oxy-fuel cutting, also known as oxygen cutting or flame cutting, is a technique that uses a high-temperature flame to cut metal materials. This technique is mainly applied to the processing of steel and other combustible metals, and is commonly used for cutting metal sheets, pipes, and profiles in industries such as construction, manufacturing, and maintenance.

[0003] The basic principle of oxy-fuel cutting is to generate a flame by mixing high-pressure pure oxygen (usually with a purity of more than 99%) with a combustible gas (such as acetylene, propane, natural gas, etc.), and heat the metal to its combustion point (for steel, this temperature is approximately 1300 degrees Celsius). When the metal reaches this temperature, the pure oxygen stream will oxidize the metal, forming slag and quickly removing it, ultimately achieving the purpose of cutting.

[0004] In previous oxy-fuel cutting operations, it was necessary to manually load the gas cylinders into the flatbed truck and then push it to the operation site, and then place them separately at a distance of 5m. This not only could not guarantee the separation distance but also could not avoid the explosion caused by the tipping of the gas cylinders. Summary of the Invention

[0005] The purpose of the utility model is to solve the problems raised in the background art, and provide a telescopic oxygen and propane cylinder trolley.

[0006] The technical solution of the utility model to achieve the above purpose is as follows:

[0007] A telescopic oxygen and propane cylinder trolley, comprising a right frame, a left frame, a placement rack, a spring, a bottom plate, a guardrail, a rotating shaft, a steering wheel, a chassis, a rotating wheel, and a locking device; the right frame is inserted into the left frame and is slidably connected to the left frame. Each side of the left frame and the right frame is fixedly connected to a placement rack. The spring is located inside the placement rack and one end of the spring is fixedly connected to the placement rack, and the other end of the spring is fixedly connected to the bottom plate. The bottom plate is slidably connected to the placement rack. The placement rack is fixedly connected to the guardrail. The right bracket is rotatably connected to the rotating shaft. One end of the rotating shaft is fixedly connected to the steering wheel, and the other end of the rotating shaft is fixedly connected to a chassis. Both sides of the chassis are respectively rotatably connected to a rotating wheel; the bottom of the left frame is fixedly connected to a chassis, and both sides of the chassis are respectively rotatably connected to a rotating wheel; the top of the left frame is fixedly connected to the locking device, and one end of the locking device is movably inserted into the top of the right frame.

[0008] Preferably, the locking device includes a support frame, a connecting shaft, a pressing plate, and a torsion spring. The support frame is fixedly connected to the left frame. Both ends of the connecting shaft are rotatably connected to a support frame respectively. The pressing plate is fixedly connected to the connecting shaft. The torsion spring is sleeved on the connecting shaft and one end thereof is fixedly connected to the pressing plate, and the other end of the torsion spring is fixedly connected to the support frame. The end of the pressing plate is inserted into the right frame.

[0009] Preferably, a fire-fighting article rack is provided on the lower side of the left frame, and the fire-fighting article rack is fixedly connected to the left frame.

[0010] Preferably, a storage box is provided on the upper side of the left frame, and the storage box is fixedly connected to the left frame.

[0011] Preferably, a storage roller is provided on the left frame, and the storage roller is rotatably connected to the left frame.

[0012] The utility model provides a telescopic oxygen and propane cylinder trolley, which has the following beneficial effects:

[0013] Through its structural design, when oxygen cutting operation is required, the oxygen cylinder and the propane cylinder are respectively placed on the placement racks on the sides of the right frame and the left frame in advance. The guardrails on the placement racks prevent the oxygen cylinder and the propane cylinder from falling off the placement racks. The springs at the bottom of the bottom plate will cushion the gravity generated by the falling of the oxygen cylinder and the propane cylinder during placement, so that the placement of the cylinder body can be completed by one person without the need for two people to operate. After laying out the gas hoses required for the oxygen cutting operation and hanging them on the left frame, the utility model can be pushed to move. When the utility model is moving, the rotating wheels on both sides of the bottom chassis of the left frame and the right frame can drive the utility model to move. When the utility model needs to be steered, turn the steering wheel. The rotation of the steering wheel drives the rotation of the rotating shaft. The rotation of the rotating shaft drives the rotation of the chassis under the right frame. The rotation of the chassis drives the rotating wheels to change the direction, thereby driving the utility model to steer. When arriving at the working location, press the locking device so that the end of the locking device is no longer inserted into the right frame. At this time, pull the left frame and the right frame to both sides respectively to change the distance between the oxygen cylinder and the propane cylinder, so that the distance between the oxygen cylinder and the propane cylinder reaches the safe operation distance. After the operation is completed, press the locking device and move the left frame and the right frame towards the center to restore the utility model to its original shape and wait for the next use. Compared with the prior art, the utility model ensures the safety of oxygen cutting operations, solves the hidden dangers caused by insufficient separation distance, and ensures the safety of the gas cylinders after separation, greatly reducing the safety hazards.

[0023] In the present utility model, the locking device 11 includes a support frame 111, a connecting shaft 112, a pressing plate 113, and a torsion spring 114. There are two support frames 111, which are respectively fixedly connected to the outer sleeves at the upper part of the left frame 2. The connecting shaft 112 is arranged inside the two support frames 111 and its two ends are respectively rotatably connected to a support frame 111. The pressing plate 113 is fixedly connected to the connecting shaft 112.

By pressing the pressing plate 113 in the locking device 11, the pressing plate 113 rotates around the connecting shaft 112 on the support frame 111. The rotation of the pressing plate 113 drives the end to be pulled out from the slot 15 on the right frame 1. At this time, the right frame 1 and the left frame 2 can be stretched to change the distance between the two placement racks 3. After the distance is changed, release the pressing plate 113, and the torsion spring 114 drives the pressing plate 113 to reset so that the end of the pressing plate 113 is inserted into the slot 15 on the right frame 1 at the current position to fix the right frame 1 and prevent the distance between the left frame 2 and the right frame 1 from changing. Through the storage box 13 on the left frame 2, some tools used by the operator can be stored, which is convenient for the operator to carry. After the operation is completed, repeat the above operation to press the locking device 11 and move the left frame 2 and the right frame 1 towards the center to restore the present utility model to its original shape and wait for the next use. Through the fire-fighting equipment rack 12 on the left frame 2, fire-fighting equipment can be placed to protect the construction safety of the operator and prevent fires.
