The Foldable overhaul workbench
Technical field
The invention belongs to power industry maintenance apparatus, particularly a kind of Foldable overhaul workbench.
Background technology
In the electric power power transmission and transformation, during the maintenance of sulfur hexafluoride breaker,, and adopt a kind of pier formula concrete foundation because there is not special-purpose platform; Switch and mechanism directly are located on the seat of basis; When mechanism overhauls, do not have enough spaces, can only use about the ladder, bring very big inconvenience to service work; Waste time and energy, and be prone to cause the personal safety fault.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, provide a kind of easy to use, good stability, the Foldable overhaul workbench of being convenient to move.
The technical scheme that technical solution problem of the present invention adopts is: the Foldable overhaul workbench comprises upper mounting plate, main pillar, horizontal stand; Be characterized between two parallel main pillars, fixedly establishing the horizontal ladder of twice level; Below two parallel main pillars, acutangulate with hinging pin shaft and flexibly connect two horizontal stands; Top at main pillar flexibly connects upper mounting plate with hinging pin shaft; Establish the fixation clip groove on the upper mounting plate front end, the outside middle of upper mounting plate and main pillar is connected an end of knighthead one and knighthead two respectively with hinging pin shaft, and the other end of knighthead one and knighthead two flexibly connects with hinging pin shaft; Knighthead two is α with the interior angle of main pillar, and α is 30 degree.
The invention has the beneficial effects as follows: the Foldable overhaul workbench can be used in the switching mechanism of electric industry system neatly; In the overhaul of the equipments work such as circuit breaker; Need decompose mechanism's working cylinder when especially switch A phase mechanism pressure release being handled, drain the oil, decompose work such as valve body and can on the service work platform, carry out; Saved the operating time greatly, increased work efficiency and fail safe, not the time spent foldable for storage.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is a Foldable overhaul workbench structure chart.
Among the figure, the 1-upper mounting plate; 1-1-fixation clip groove; 2-knighthead one; 3-knighthead two; The 4-hinging pin shaft; 5-master's pillar; The 6-horizontal stand; The horizontal ladder of 7-level.
Embodiment
Embodiment; With reference to accompanying drawing 1, the Foldable overhaul workbench is to utilize the square tube of 50 * 20 * 3mm to weld and form with hinged being hinged by bearing pin 4, and the height of its main pillar 5 is 1140mm; Between two main pillars 5 with the 7 parallel welding of the horizontal ladder of two levels together, between the two main pillars 6 apart from 600mm.Below main pillar 5, flexibly connect with hinging pin shaft 4 with acute angle in 6 one-tenth of the levels, horizontal stand 6 is long to be 540mm.Top at main pillar 5 is hinged with upper mounting plate 1 with hinging pin shaft 4, on the front end of upper mounting plate 1, establishes fixation clip groove 1-1.An end that is connected support bar 23 and support bar 1 in the middle of main pillar 5 and upper mounting plate 1 respectively with hinging pin shaft 4 respectively; The other end of support bar 1 and support bar 23 is hinged together with hinging pin shaft 4; Make support bar two become the α angle with main pillar 5 interior angles, the α angle is 30 degree.Below the upper mounting plate 1 with support bar 23 and main pillar 5 pin joints apart from 400mm.Front end with upper mounting plate 1 during use overlaps on the seat of the basis of equipment; Be pressed in fixed head indent 1-1 with fixation clip and go up and lock with anchor bolt nut, the people can carry out work above the upper mounting plate 1 of workbench from the horizontal ladder 7 of the level on the main pillar 5, and the time spent can not unclamped bolt and nut; Workbench is taken down; Direction stored collapsed along arrow indication in the accompanying drawing 1 does not take up space, and is easy to use and reliable.
