The engine pit of adjustable width
Technical field:
The utility model relates to the engine pit of a kind of engine pit, particularly a kind of adjustable width.
Background technology:
In industrial enterprise's vehicle maintenance and repair plant design, engine pit need be set usually overhaul parts such as car chassis.General industrial enterprise vehicle fleet is not a lot, and in order to save the area and to reduce construction investment, normally the relative dimensions according to the most of vehicles that use in the enterprise is provided with an engine pit.But because the complexity of factory's transportation, the vehicle of factory's operation has small passenger car, este wagon, motorcoach, small-sized bogie, large-scale bogie, also has engineering truck special-purpose on the production technology.The wheelspan of these vehicles is different.In general, vehicle is big more, and wheelspan is wide more.Because the variety of vehicle only is provided with an engine pit, can cause part car inspection and maintenance inconvenience maybe can't overhaul.For example, if pressing the wheelspan of full size vehicle, the width of service pit determines that the wheelspan of dilly is less so, just can not use; Otherwise if determine the width of service pit by the wheelspan of dilly, just may not overhaul at some position of full size vehicle.
Summary of the invention:
The purpose of this utility model is: a kind of engine pit of adjustable width is provided, and its vehicle that can adapt to different wheelspans uses when the maintenance chassis, to solve the deficiency that prior art exists.
The utility model is to constitute like this: it is made up of the active supporting plate (2) of cheating body (1) and be contained on body (1) end face of hole, on active supporting plate (2), be provided with chute (3), be connected with bolt of rear end plate (4) and nut (5) on chute (3), bolt of rear end plate (4) links to each other with hole body (1).
Compared with prior art, the utility model is adjusted the end face width of service pit by the sway active supporting plate, make the width of service pit to regulate arbitrarily, the car inspection and maintenance that can adapt to various wheelspans is used, under the condition that does not increase the occupation of land of construction investment and factory, satisfied the maintenance needs of the multiple vehicle of industrial enterprise preferably, have simple in structure, small investment, easy to use, satisfied the advantages such as maintenance needs of different automobile types preferably.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment:
Embodiment of the present utility model: the engine pit of adjustable width of the present utility model is made up of hole body 1 and the active supporting plate 2 that is contained on body 1 end face of hole, wherein cheating body 1 forms for the cement concrete cast, active supporting plate 2 adopts steel plate to make, on an end of active supporting plate 2, be provided with chute 3, so that active supporting plate 2 horizontally slips, on chute 3, be connected with bolt of rear end plate 4, on bolt of rear end plate 4, be connected with nut 5, the bottom of bolt of rear end plate 4 is cast in the ground of hole body 1, so that the active supporting plate of adjusting 2 is fixing, prevent that active supporting plate 2 from toppling because of the pressure of automobile.
When the maintenance automobile, elder generation adjusts active supporting plate 2 according to the Track width of the automobile of Awaiting Overhaul, the end face width of hole body 1 and the Track width of automobile are adapted, fastening nut 5 then, make active supporting plate 2 fixing getting final product, after this, the automobile that overhaul just can reach safely on the maintenance position and carry out upkeep operation.
