Description

Technical Field

[0001] This invention relates to the field of loading skid technology, and in particular to a top and bottom double skid. Background Technology

[0002] Currently, most skids commonly used in China are single-type skids, which connect pipes, valves, control cabinets, electrical instruments, etc. into a whole according to a certain process flow. The whole is fixed to the steel or other structures by welding, bolting and other methods to realize the function of loading or unloading. A skid can basically only realize bottom loading or top loading within a unit of time, resulting in low loading efficiency and limited loading operation methods. Moreover, the external structure of the entire skid occupies a lot, making it very inconvenient to store or transport during off-peak hours. Summary of the Invention

[0003] The technical problem to be solved by this invention is that currently, domestic loading skids can basically only achieve bottom loading or top loading within a unit of time, resulting in low loading efficiency, limited loading operation methods, and a large external structure of the entire skid, which makes it very inconvenient to store or transport during off-peak hours.

[0004] The technical solution adopted by this invention to solve its technical problem is: a top-bottom double skid, comprising a double-layer skid, two gas supply pipes installed at the lower end of the double-layer skid, two liquid supply pipes installed at the lower end of the double-layer skid, an angle-adjustable bottom-mounted liquid phase arm and an angle-adjustable bottom-mounted gas phase arm installed at the lower layer of the double-layer skid, and an angle-adjustable top-mounted liquid phase arm and an angle-adjustable top-mounted gas phase arm installed at the upper layer of the double-layer skid. The liquid supply pipe on one side of the lower end of the double-layer skid is connected to a bottom-mounted flow meter, a bottom-mounted electro-hydraulic valve, and a bottom-mounted temperature sensor. The transmitter and the bottom-mounted pneumatic shut-off valve are connected to the angle-adjustable bottom-mounted liquid phase arm. The liquid delivery pipe on the other side of the lower end of the double-layer skid is connected to the angle-adjustable top-mounted liquid phase arm through the top-mounted flow meter, the top-mounted electro-hydraulic valve, the top-mounted temperature transmitter, and the top-mounted pneumatic shut-off valve. The two gas delivery pipes at the lower end of the double-layer skid are connected to the angle-adjustable bottom-mounted gas phase arm and the angle-adjustable top-mounted gas phase arm through gas delivery pipes, respectively. The upper surface of the double-layer skid is equipped with a top-side support platform that can be electrically controlled to move and can be flipped and stored.

[0005] The outer side of the double-layer pry bar is equipped with a detachable inclined climbing ladder located on one side of the upper support platform. The outer sides of the upper surfaces of the double-layer pry bar, the top support platform, and the detachable inclined climbing ladder are all fixed with side guardrails to improve operational safety.

[0007] The upper support platform of the double-layer skid is fixedly equipped with a horizontal assembly cylinder at its lower end. The horizontal assembly cylinder is fixedly installed with a built-in hydraulic strut for controlling the extension and retraction of the side-mounted adjusting guide rail. The rear side wall of the side-mounted adjusting guide rail is fixedly equipped with a side-mounted assembly bushing for axially connecting the front extension rod of the built-in hydraulic strut.

The top side support platform is movably connected to the electrically controlled translation assembly base through the side assembly brackets via two side assembly shafts.

[0009] The lower surface of the internal threaded translation seat is movably fitted with a bottom-mounted flip-limiting plate, and the internal threaded translation seat is movably fitted with a built-in transmission gear set for transmitting power between the top side support platform and the bottom-mounted flip-limiting plate.

[0010] The outer surface of the double-layer skid is movably fitted with a longitudinal electrically controlled strut for controlling the rotation of the top support platform.

[0011] Both sides of the upper surface of the double-layer pry bar are welded and fixed with side guide rails for sliding and storing the detachable inclined climbing ladder. The upper surface of the side guide rails is provided with upper telescopic limit through holes for internal installation of locking bolts.

[0012] An electrostatic grounding box is installed on one side of the inner bottom surface of the double-layer skid.

[0013] A top connecting cover is fixedly mounted on the outer connecting pipe of the angle-adjustable top-mounted liquid phase arm and the angle-adjustable top-mounted gas phase arm, and a connecting vertical pipe is axially fixed at the lower end of the top connecting cover.

[0014] The beneficial effects of this invention are:

[0047] 1) Top and bottom double skid grounding, tank car grounding (static grounding clamp).

[0048] 2) If it is a bottom-loading tank truck, connect the angle-adjustable bottom-loading liquid phase arm 4 and the angle-adjustable bottom-loading gas phase arm 5 to the tank truck through API connectors.

[0049] 3) Open the bottom loading electro-hydraulic valve 8, bottom loading temperature transmitter 9 and bottom loading pneumatic shut-off valve 10 on the main pipeline at the set flow rate to start loading at a small flow rate.

[0050] 4) When the design flow rate is reached, the opening of the electro-hydraulic valve increases to load a large flow rate. When the set loading volume is about to be reached, the opening of the bottom loading electro-hydraulic valve 8 decreases to load a small flow rate until the set loading volume is reached.

[0051] 5) Empty the pipeline and finish loading. Manually disconnect the API connector at the tank truck end, and the bottom loading pneumatic shut-off valve 10 on the main pipeline will automatically close.

[0054] 8) When the design flow rate is reached, the opening of the top loading electro-hydraulic valve 11 increases to load at a large flow rate. When the set loading volume is about to be reached, the opening of the top loading electro-hydraulic valve 11 decreases to load at a small flow rate until the set loading volume is reached.

[0055] 9) Empty the pipeline and finish loading. Manually pull out the connecting vertical pipe 30. The pneumatic shut-off valve 133 at the top of the main pipeline will automatically close.
