[0001] The utility model relates to the technical field of metering pry, in particular to a metering pry with a stable pry seat structure. Background Art
[0002] A metering skid is a complete set of equipment, usually used in specific industrial applications, such as liquefied natural gas (LNG) storage stations. It consists of multiple key components, including valves, filters, pressure regulators, flow meters, shut-off valves, safety relief valves and odorizers, which work together to provide a reliable and stable gas supply. The design of the metering skid takes into account the needs of specific working conditions and aims to simplify the complexity of on-site construction while ensuring the safety and stability of the system.
[0003] The existing metering pry has a simple structure and single function at the bottom pry seat. When the metering pry needs to be moved, it cannot provide an upward lifting force for the metering pry, so it cannot assist in exerting force to allow the metering pry to be steadily lifted off the ground. When using tools such as a crowbar to move the metering pry, there may be a problem of uneven force application, which can easily cause the metering pry to move unsteadily or even fall and be damaged.
[0004] Therefore, those skilled in the art provide a metering skid with a stable skid seat structure to solve the problems raised in the above background technology. Utility Model Content

A pressing plate is also connected under the connecting plate. When the two mounting frames approach each other, the supporting wing plates will rotate downward and touch the pressing plate to the ground.

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1 to Figure 4 The present invention provides a metering skid with a stable skid structure, comprising: a skid 1, a skid opening 2 is evenly arranged around the outer side surface of the skid 1, and a placement base plate 3 is embedded and installed on the upper surface of the skid 1, a metering pump unit 4 is installed above the placement base plate 3, hydraulic oil ports 5 are arranged at the front and rear positions of the right side of the upper surface of the skid 1, and slide grooves 6 are arranged on the inner walls of the front and rear sides of the skid 1, and hydraulic telescopic rods 7 are arranged on the inner sides of the slide grooves 6, both ends of the hydraulic telescopic rod 7 are connected with sliders 9, and the head and tail ends of the hydraulic telescopic rod 7 are connected with mounting frames 10, the input end of the hydraulic telescopic rod 7 is provided with a hydraulic oil injection port 8, and the hydraulic oil injection port 8 passes through the inside of the slider 9 on one side, the slider 9 is fixedly connected to the head and tail ends of the hydraulic telescopic rod 7, and the size of the slider 9 and the slide groove 6 is matched to form a slidable structure, the slider 9 is fixedly connected to the two ends of the mounting frame 10, and the cross section of the mounting frame 10 is "L" shaped;
[0023] Specifically, the hydraulic oil injection port 8 is connected to the hydraulic oil port 5 through a pipeline, and the hydraulic oil injected from the hydraulic oil port 5 will enter the hydraulic telescopic rod 7 through the hydraulic oil injection port 8. As the hydraulic oil in the hydraulic telescopic rod 7 continues to flow into the hydraulic telescopic rod 7, the hydraulic telescopic rod 7 begins to extend under the action of the hydraulic pressure, and conversely contracts, thereby realizing the distance adjustment between the two mounting frames 10. By adjusting the distance between the mounting frames 10, the lifting action can be completed, thereby assisting the metering skid to complete the moving work.
[0024] A connecting rod 11 is fixed to the inner side of the opening side of the mounting frame 10, and a sleeve 12 is sleeved on the outside of the connecting rod 11, a supporting wing plate 13 is fixed to the outer wall of the sleeve 12, and a connecting plate 14 is connected to the bottom of the supporting wing plate 13, a hinge 15 is connected between the supporting wing plate 13 and the connecting plate 14, and the supporting wing plate 13 forms a rotating structure with the connecting rod 11 through the sleeve 12;
[0025] Specifically, the support wing plate 13 and the connecting plate 14 are rotatably connected by hinges 15, so the angle between the two can be adjusted. At the same time, the support wing plate 13 can be rotated on the connecting rod 11 by using the sleeve 12. When the two mounting frames 10 are close to each other under the contraction of the hydraulic telescopic rod 7, the inclination angle of the support wing plate 13 will change, and the angle between the support wing plate 13 and the connecting plate 14 will also increase accordingly. At this time, after the pressure plate 16 touches the ground, the metering pry will be lifted up due to the supporting effect of the support wing plate 13, so that it is convenient for the staff to move the metering pry smoothly without worrying about the uneven force caused by operational errors. On the contrary, when the two mounting frames 10 are far away from each other, the support wing plate 13 is gradually flattened, the pressure plate 16 is off the ground, and the pry seat 1 can be placed stably on the ground.
[0026] A pressure plate 16 is fixed below the connecting plate 14, and a torsion spring 17 is provided between the pressure plate 16 and the supporting wing plate 13. A 5 cm gap is left between the pressure plate 16 and the connecting plate 14, and a slot structure for installing the torsion spring 17 is provided on the upper surface of the pressure plate 16 and the lower surface of the supporting wing plate 13;
[0027] Specifically, the function of the torsion spring 17 is to ensure good connection elasticity between the pressure plate 16 and the supporting wing plate 13. When the metering pry is lifted up, the torsion spring 17 is in a stretched state, which provides elastic support and vibration relief for the pry seat 1. When the metering pry is laid flat on the ground, the elasticity of the torsion spring 17 enables the pressure plate 16 and the supporting wing plate 13 to be well retracted, so that the pressure plate 16 has a tendency to lift up during the process of leaving the ground, which can also alleviate some of the pressure damage.
[0028] The working principle of the utility model is:
[0029] When it is necessary to use the crowbar to move the metering pry, hydraulic oil is first extracted from the hydraulic oil injection port 8 through the hydraulic oil port 5. As the hydraulic oil is continuously extracted, the hydraulic telescopic rod 7 gradually contracts, and the two mounting frames 10 move closer to each other through the sliding cooperation between the slider 9 and the slide groove 6. At this time, the support wing plate 13 will rotate downward at an angle and touch the pressure plate 16 to the ground. As the hydraulic telescopic rod 7 continues to contract, the rotation angle of the support wing plate 13 becomes larger, gradually lifting the entire pry seat 1, and the pry seat 1 is off the ground. Then, the crowbar is inserted into the crowbar opening 2, and the entire metering pry can be easily and smoothly moved. To put the metering pry flat on the ground, hydraulic oil needs to be input into the hydraulic oil injection port 8 through the hydraulic oil port 5, and the hydraulic telescopic rod 7 gradually extends, and the two mounting frames 10 move away from each other. At this time, the support wing plate 13 will gradually flatten, and the pressure plate 16 will also smoothly leave the ground under the action of the torsion spring 17.
[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
