Abstract
The utility model relates to a spring type floating roof storage tank paraffin scraper provided with a stress application mechanism, which is used for a storage tank in the field of storage and transportation of the oil field. Positioning steel angles in the device are circumferentially and uniformly fixed on a lower plane of a storage tank floating pontoon; and a transition piece is fixed on each positioning steel angle through a bolt group, the lower end of the transition piece is welded with a sleeve assembly, a support rod is sleeved with the sleeve assembly, one end of the support rod is connected with a press block and a pin shaft of a paraffin scraping plate, a compression spring is mounted between the end part of the support rod and the sleeve assembly in a sleeved manner, prefabricated threads are formed at the other end of the support rod, and pressure of the spring to the tank wall is adjusted by an adjusting nut. The device is simple and compact in structure and convenient to mount, and after mounting, a paraffin scraping piece is higher than a paraffin scraping piece of a conventional paraffin scraper, so that when the bottom plate of the floating pontoon is closer to a manhole of the tank wall, the paraffin scraping plate of a paraffin scraping mechanism is prevented from colliding with the manhole.
Description
Technical field
The utility model relates to a kind of tank skin wax scraping apparatus in storage tank used in accumulating field, oil field, specifically a kind of spring boosting mechanism floating roof tank wax scraping apparatus.
Background technology
At present, domestic and international many floating top oil tanks are used Weight type wax scraping apparatus, and this device, by linkage, utilizes lever principle, applies thrust, and drive waxing scraper to move up and down with floating plate by counterweight by briquetting to waxing scraper.This wax scraping apparatus is mainly comprised of two parts: waxing scraper and boosting mechanism.Its boosting mechanism is quadric chain, as Fig. 1.Weight type paraffin scraping mechanism shortcoming is that 1. boosting-rod is longer, needs larger space in storage tank, often causes boosting-rod or counterweight and pontoon pillar to collide.2. waxing scraper more on the lower, for those pontoon base plates storage tank nearer apart from shell manhole, often causes waxing scraper and manhole to collide.
Utility model content
In order to overcome the deficiency in background technology, the utility model provides a kind of floating roof petroleum storage tank paraffin cutting sealing device.This apparatus structure is simply compact, easy for installation, and rear paraffin scraper position is installed, and wax scraping apparatus paraffin scraper position was top more in the past, thereby while having avoided pontoon base plate nearer apart from shell manhole, waxing scraper and the manhole of paraffin scraping mechanism collide.
The technical solution of the utility model is: a kind of spring boosting mechanism floating roof tank wax scraping apparatus, comprise some location angle steel, sleeve assembly, support bar, Compress Spring and adjusting nut, above-mentioned location angle steel is circumferentially on the uniform lower plane that is fixed on pontoon in storage tank, on each location angle steel, by bolt group, fix excessive part, the lower end fixed muffle assembly of excessive part, sleeve assembly is sleeved on above-mentioned support bar, one end of support bar is by split pin, packing ring and bearing pin connect briquetting, described briquetting is by another group split pin, packing ring and bearing pin are connected with scraper plate, in support bar section between support bar step and sleeve assembly, be set with Compress Spring, the other end of support bar has pre-threaded, coordinates adjust the pressure of Compress Spring to reservoir walls with adjusting nut.
As preferably, the upper and lower side of above-mentioned scraper plate is corrugated plate shape, and plate rib contacts with reservoir walls camber line.
The beneficial effects of the utility model are: above-mentioned spring boosting mechanism floating roof tank wax scraping apparatus, utilization is fixed on sleeve assembly and the built-in support bar thereof of pontoon bottom and is sleeved on spring and the adjusting nut on support bar, thereby the briquetting that makes to be fixed on adjusting lever end compresses scraper plate, realizes the object to reservoir walls paraffin cutting; This apparatus structure is compact, simple in structure, deutomerite save space is installed, effectively solved in the past Weight type wax scraping apparatus because thereby waxing scraper is collided and caused the problems such as paraffin scraper distortion, paraffin cutting are incomplete with shell manhole more on the lower, and the counterweight of having avoided Weight type paraffin scraping mechanism in the past and the interior pontoon pillar of the tank problem of colliding.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the B of Fig. 1 is to view;
Fig. 3 is the expansion schematic diagram of the utility model in tank.
1-location angle steel in figure, 2-bolt group, 5-adjusting nut, 6-support bar, 7-sleeve assembly, 8-Compress Spring, 9-split pin, 10-packing ring, 11-bearing pin, 12-briquetting, 13-scraper plate, 14-reservoir walls, 15-sleeve, 16-pontoon, the excessive part of 17-, 18-split pin, 19-packing ring, 20-bearing pin.
The specific embodiment
Shown in Fig. 1 and Fig. 3, this spring boosting mechanism floating roof tank wax scraping apparatus, comprise some location angle steel 1, sleeve assembly 7, support bar 6, Compress Spring 8 and adjusting nut 5 etc., above-mentioned some location angle steel 1 is circumferentially on the uniform lower plane that is weldingly fixed on pontoon 16 in storage tank, on each location angle steel 1, by bolt group, fix excessive part 17, excessively the lower end of part 17 is welded and fixed sleeve assembly 7, in sleeve assembly 7, be installed with above-mentioned support bar 6 and two ends reach outside sleeve assembly, the left external part of support bar 6 is by split pin 18, packing ring 19 and bearing pin 20 connect briquetting 12, as shown in Figure 3, described briquetting 12 is by another group split pin 9, packing ring 10, bearing pin 11 is scraper plate 13 fixedly, and is set with Compress Spring 8 in the support bar section of 7 of the shaft shoulder of support bar 6 and sleeve assemblies, and the two ends of Compress Spring 8 are located by the end face of support bar assembly 6 shaft shoulders and sleeve 15 respectively, the other end of support bar 6 has pre-threaded, and coordinates with adjusting nut 5, and support bar 6 is moved axially, thereby adjusts the pressure of 8 pairs of reservoir walls 14 of Compress Spring, thereby scraper plate 13 is tightly affixed in reservoir walls 14, as shown in Figures 1 and 2.
As preferably, the upper and lower side of above-mentioned scraper plate 13 is corrugated plate shape, and plate rib contacts with reservoir walls 14 camber lines, is close to tank skin, in pontoon lifting process, plays paraffin cutting effect.
Upper this wax scraping apparatus is to utilize be fixed on sleeve assembly and the built-in support bar thereof of pontoon bottom and be sleeved on spring and the adjusting nut on support bar, thereby make briquetting that adjusting lever end connects by bearing pin compress scraper plate, realizes the object to reservoir walls paraffin cutting; This apparatus structure is compact simple, deutomerite save space is installed, effectively solved in the past Weight type wax scraping apparatus because thereby waxing scraper is collided and caused the problems such as paraffin scraper distortion, paraffin cutting are incomplete with shell manhole more on the lower, and the counterweight of having avoided Weight type paraffin scraping mechanism in the past and the interior pontoon pillar of the tank problem of colliding.
