Problems solved by technology
The overall length of this gas cylinder trolley is too long, and it is integrally welded. Therefore, the gas cylinder trolley occupies a large space, and the limited space of the existing wellhead control cabinet cannot accommodate it at all. The nitrogen cylinder trolley cannot be stored nearby. This makes it inconvenient to replace the nitrogen cylinder

Embodiment Construction
[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0024] like figure 1 , figure 2 , image 3 , Figure 5 , Image 6 A gas cylinder telescopic folding trolley shown includes a load-bearing base plate 1, a main push frame 2, a telescopic pull rod 6, a support arm 12 and a folding mechanism 14, and the main push frame 2 includes a bracket 201 and a push rod 202. Two rods 202 are arranged parallel to each other, and a roller 13 is installed at the bottom of the push rod 202; the brackets 201 are arranged parallel to each other, and the two ends of each bracket 201 are welded and fixed to the push rod 202 respectively. The bracket 201 is an arc-...

The invention provides a gas cylinder telescopic folding cart, which includes a main push frame, a telescopic pull rod, a support arm, a folding mechanism and a load-bearing bottom plate connected to the bottom of the main push frame. The main push frame is fixedly connected by a bracket and a push rod. A hollow cavity is provided on the push rod, and the telescopic pull rod and the push rod are movably socketed, and the push rod forms a movable hinge structure through the connecting piece and the support arm, and the folding mechanism is hinged into one body by two connecting pieces , one end of which is articulated with the push rod, and the other end is articulated with the support arm. A locking mechanism is set between the telescopic pull rod and the push rod. When the telescopic pull rod is stretched a certain distance relative to the push rod, the telescopic pull rod will Stay locked with push rod. The invention can minimize the occupied space of the gas cylinder telescopic and folding trolley itself, greatly facilitates the nearby storage of the gas cylinder telescopic and folding trolley, so as to facilitate the replacement of gas cylinders.
Description
technical field [0001] The invention relates to a gas cylinder trolley, in particular to a gas cylinder telescopic folding trolley. Background technique [0002] Natural gas wellhead control cabinets may need to be powered by nitrogen cylinders. Nitrogen cylinders are consumed as they are used, so they need to be replaced regularly. Therefore, gas cylinder trolleys are essential equipment. [0003] In the existing gas cylinder trolley, the main structure for accommodating the nitrogen cylinder body is an integral welded structure, and an iron chain is used as an auxiliary for fixing the cylinder body. In actual use, the load-bearing bottom plate in the gas cylinder trolley needs to be shoveled to the bottom of the nitrogen cylinder, and then the operator forcefully tilts the nitrogen cylinder and makes it stick to the above-mentioned main structure containing the nitrogen cylinder, and then uses iron chains to assist Fixed, the nitrogen cylinder can be moved to the designat...
