Abstract
The utility model relates to a self-controlling level unit. The two ends of a level induction tube and the two ends of a three-position four-way solenoid valve are connected via wires to form alternating current or direct current circuits. A hydraulic pressure (air pressure) cylinder body and a hydraulic pressure (air pressure) valve are connected to form a hydraulic pressure (air pressure) system through an oil (air) pipe. The utility model has the advantages of simple structure and convenient maintenance, and can be used as the horizontal table of the dynamic system of a ship, a naval, various vehicles, a train, an aircraft, etc., the level engine bed for surveying instruments and devices, the level base for military instruments, beds and dining tables, and all the facilities that need to keep horizontal in a dynamic or static systems. Particularly, the self-controlling level unit can make the vehicle body in level condition all the time when the vehicle is running or turning the corner at a high speed.
Description
The utility model belongs to and utilizes hydraulic pressure and air pressure principle to make the horizontal operation table top remain a kind of automatic control horizontal device of level.
Existing horizontal operation table top is each position that level meter, chi is placed on table top, respectively with all directions with the level of transferring to.Transfer to the work top of level in this way, ability maintenance level in static system, the instrument of these level-ofves can only use in static system.
The purpose of this utility model is to provide a kind of horizontal operation table top device of controlling level voluntarily that makes, and not only conveniently is used for static system, and is applicable in the dynamic system.
The method that the utility model is finished is that horizontal induction tube is fixed on the horizontal stand, each induction tube control one cover hydraulic pressure or pneumatic system, the piston rod of liquid (gas) cylinder pressure cooperates with the linkage assembly that is supporting horizontal stand by the curved surface of slide block, carries out the transmission of power.In dynamic system, make work top remain level, generally be equipped with two and can respond to the horizontal induction tube that front, rear, left and right tilt, and two cover liquid (gas) pressing systems.According to the requirement of horizontal stand horizontal accuracy, can increase and decrease the length of induction tube and the sensitivity of induction tube, and the quantity of corresponding increase liquid (gas) cylinder pressure; The weight size of being born according to the horizontal operation table top can corresponding improve or reduce the working pressure of liquid (gas) pressing system.
The utility model has the advantages that: (1) is simple in structure, makes easy to maintenance; (2) practical wide, can be used as the horizontal table on the dynamic systems such as steamer, naval vessels, various vehicle, train, aircraft, the horizontal support of instrument of surveying and mapping, equipment; All need keep the facility of level in the horizontal base of military apparatus and bed, dining table and the dynamic and static system, particularly in the vehicle ' process and when at a high speed turning the gulf car body are remained in horizontality.
Accompanying drawing is a kind of one-piece construction figure of the present utility model.
A kind of embodiment of the present utility model is: the horizontal induction tube (2) that conductive liquid (3) is housed is fixed on the horizontal operation table top (4), quadrilateral connecting rod mechanism (1), (7) upper end self-aligning spherical support work top, the lower end latch is fixed on liquid (gas) the pressing system fixing body (11), two bar liquid (gas) the cylinder pressure bodies (5) of double acting are installed in the appropriate location of liquid (gas) pressing system fixing body (11), slide block (8) (6) in the middle of piston rod (9) (10) withstands respectively, the two ends of three position four-way electromagnetic valve (12) are connected into horizontal induction tube two ends by lead respectively and exchange or DC circuit.During work, when if the left side of work top is downward-sloping, conductive liquid in the horizontal induction tube flows to left end immediately, the left end circuit of at this moment horizontal induction tube and three position four-way electromagnetic valve is connected, its position, left side work of three position four-way electromagnetic valve, pressure oil (gas) enters the right chamber of oil cylinder, and meanwhile, the oil (gas) in chamber, an oil cylinder left side enters fuel tank by three position four-way electromagnetic valve, left end piston rod (9) heads on left end slide block (8) and slides left, the upper and lower side angle of left side quadrilateral connecting rod mechanism diminishes, and left side work top rises, and right piston rod (10) retreats simultaneously, the right quadrilateral connecting rod mechanism top angle up and down becomes big, slide block (6) is slided left, and the right table top descends simultaneously, when work top is up to the standard, the conductive liquid level, circuit disconnects, and three position four-way electromagnetic valve is multiple to be disconnected to meta oil (gas) road, and oil cylinder is not worked.If work top the right is downward-sloping, conductive liquid in the horizontal induction tube flows to the induction tube right-hand member, the right circuit is connected, three position four-way electromagnetic valve right position work, pressure oil (gas) enters the left chamber of oil (gas) cylinder, oil (gas) in the right chamber enters oil (gas) case by three position four-way electromagnetic valve, at this moment, owing to retreat in the time of the propelling of right piston rod and left piston bar, right, left side quadrilateral connecting rod mechanism upper and lower side angle diminishes respectively and increases, work top is to level, and circuit disconnects, and three position four-way electromagnetic valve is multiple to meta, liquid (gas) pressing system quits work, in like manner, in order to make work top front and back maintenance level, as long as the device of automatic control front and back level is installed.To the automatic control horizontal device be installed in other angles of horizontal operation table top, can realize the purpose of automatic control level simultaneously.
Claims (2)
1, a kind of automatic control horizontal device, comprise quadrilateral connecting rod mechanism [1] [7], two bar liquid (gas) cylinder pressures [5] of double acting, three position four-way electromagnetic valve [12], liquid (gas) pressure system, it is characterized in that the horizontal induction tube [2] that conductive liquid [3] is housed is installed on the level table [4], upper end self-aligning spherical support by quadrilateral connecting rod mechanism [1] [7] work top, the lower end latch is fixed on system's fixing body [11] that two bar liquid (gas) the cylinder pressure bodies [5] of double acting are installed, by lead the two ends of horizontal induction tube and three position four-way electromagnetic valve are linked to each other, become to exchange or DC circuit, by oil (gas) pipe, press liquid (gas) cylinder pressure body and liquid (gas) valve to connect to form liquid (gas) pressing system.
2, horizontal device according to claim 1 is characterized in that by the slide block that piston rod promotes curved surface being arranged.
