Description

Technical Field

[0001] The utility model relates to an adjustable bracket for gas cylinder inspection, belonging to the technical field of gas cylinder inspection equipment. Background Art

[0002] As a key device for storing compressed gas, the safety and integrity of gas cylinders are of crucial importance. During regular inspections, the traditional method is usually to place the gas cylinder on a fixed inspection bracket or directly flat on the ground to check its internal structure and appearance. However, this method has obvious limitations. On the one hand, when it is necessary to manually turn the gas cylinder to comprehensively check its appearance, this process is not only time-consuming and laborious, but also easily causes unnecessary wear to the paint layer on the surface of the gas cylinder, affecting its aesthetics and protective effect. On the other hand, if the ground in the inspection area is uneven, the gas cylinder may roll by itself, which not only increases safety hazards, but also greatly reduces the efficiency and accuracy of the inspection work. Even if there are brackets designed specifically for gas cylinder inspection on the market, most of them are of fixed design, lacking flexibility and portability, and it is difficult to meet the requirements of different inspection scenarios, thus bringing many inconveniences in practical applications.

[0003] Therefore, it is particularly important to explore an auxiliary tool for gas cylinder inspection that can effectively protect the surface of the gas cylinder, improve the inspection efficiency, and is easy to operate and highly adaptable. Content of the Utility Model

[0004] According to the deficiencies in the above prior art, the technical problem to be solved by the utility model is: to provide an adjustable bracket for gas cylinder inspection to solve the above problems.

[0005] The adjustable bracket for gas cylinder inspection described in the utility model includes a fixed base, a rotating base is provided on the fixed base, the rotating base is rotatably connected to the fixed base, a pair of roller supports for supporting the gas cylinder are provided on the rotating base, the two roller supports are parallel to each other and have the same height, and the distance between the two roller supports can be adjusted under the drive of a lead screw.

[0006] Wherein, each roller support is respectively arranged between a pair of brackets, the bottom of the bracket is fixed on a slider, and the slider is slidably arranged on a slide rail; one side of the slider is fixedly connected to a lead screw nut, and the lead screw nut is arranged on the lead screw and is in threaded cooperation with the lead screw.

[0007] In addition, the two lead screw nuts on the same side are arranged on the same lead screw, and the front section and the rear section of the lead screw are respectively provided with right-handed threads and left-handed threads.

[0008] The lead screw of the utility model is connected to a rocker through a bevel gear set and a transmission rod, and the two lead screws are both connected to the same rocker.

[0009] Preferably, the roller support adopts a rubber-coated roller.

[0010] The fixed base serves as a stable foundation for the entire bracket, used to support and fix other components. The rotating base is rotatably connected to the fixed base, allowing the gas cylinder to rotate within the horizontal plane for convenient all-round inspection. The idler rollers are arranged on the rotating base, with two in total, parallel to each other and of equal height, for supporting the gas cylinder. The idler rollers adopt the design of rubber-coated drums to reduce friction and damage to the surface of the gas cylinder. By rotating the lead screw, the lead screw nut moves on the lead screw, thereby driving the slider and the idler rollers to slide on the slide rail, realizing the adjustment of the distance between the two idler rollers to accommodate gas cylinders of different sizes. In particular, the two lead screw nuts on the same side are arranged on the same lead screw, and the front section and the rear section of the lead screw adopt right-handed and left-handed thread designs respectively to ensure that the two idler rollers can move synchronously and in opposite directions. The rotational motion of the rocker is converted into the rotational motion of the lead screw through the bevel gear set, and both lead screws are connected to the same rocker to achieve synchronous drive, with simple operation.

[0011] The beneficial effects of the present utility model compared with the prior art are as follows:

[0012] 1. Protect the surface of the gas cylinder: Using rubber-coated drums as idler rollers can effectively reduce friction and damage to the surface of the gas cylinder.

[0013] 2. Improve inspection efficiency: Through the design of the rotating base and adjustable idler rollers, rapid rotation and stable support of the gas cylinder are achieved, facilitating all-round inspection and reducing inspection time.

[0014] 3. Simple operation: Synchronous drive is achieved by using the bevel gear set and the transmission rod. The distance between the idler rollers can be adjusted by a single rocker, with simple and fast operation.

[0015] 4. Strong adaptability: The adjustable idler roller design is applicable to the inspection of gas cylinders of various sizes, improving the versatility and flexibility of the bracket. BRIEF DESCRIPTION OF THE DRAWINGS
