Abstract

The utility model discloses a hydraulic horizontal moving door provided with a power operating mechanism which horizontally moves a wing by a pressurizing medium. The hydraulic horizontal moving door with compact structure, small volume, safe use, and adjustable speed and without impact force in opening and closing is composed of a door body and a power operating mechanism. The lower part of the door body is provided with two rolling wheels move on a track. The power operating mechanism is composed of a hydraulic driving system and a mechanical transmission system, wherein, the hydraulic driving system is provided with a motor variable pump, a three-position four-way electromagnetic change valve, a stop valve and an oil motor, and the mechanical transmission system is provided with a gear arranged on the output shaft of the oil motor, and a toothed rack arranged on the lower part of door body.

Description

Hydraulic translation door

The utility model belong to band move horizontally by means of pressure medium wing power-operated mechanism move horizontally door.

The gate open of using that moves horizontally often adopts motor-reduction box power-operated mechanism at present, with the door that moves horizontally of this power-operated mechanism, not only volume is big, closes when opening impact force adjustable speed not greatly, particularly when travel switch is malfunctioning, recurring structure damage accident easily.

For provide a kind of compact conformation, volume little, safe and reliable, close the door that moves horizontally that does not have impact force and adjustable speed when opening, the utility model is proposed.

The utility model is made up of door body and power-operated mechanism.Door body bottom has two rollers, roller places on the track that is embedded in the basis, and track-movable, power-operated mechanism is made up of fluid power system and machine driven system, fluid power system has motor and through motor-driven variable pump, the oil-in of variable pump communicates with fuel tank through oil filter, the oil-out of variable pump communicates with oil motor through the 3-position 4-way solenoid operated directional valve, on the oil circuit between 3-position 4-way solenoid operated directional valve and the variable pump, overflow valve is housed, the stop valve that is equipped with in parallel on the oil circuit between 3-position 4-way solenoid operated directional valve and the oil motor; Machine driven system is by being installed in the gear on the oil motor output shaft and forming with the tooth bar of gears engaged, also can be by being installed in the sprocket wheel on the oil motor output shaft and forming with the chain of sprocket engagement, tooth bar or chain are installed in a body bottom, and fluid power system is installed in the cavity of door pillar.

Because the utility model has adopted the fluid power system of being made up of motor, variable pump, 3-position 4-way solenoid operated directional valve and oil motor, omitted bulky reduction box, and can reach the speed of regulating closing-opening door through the output of regulated variable pump, the 3-position 4-way electromagnetism of fluid power system changes and valve and overflow valve, door closed when opening do not have impact force, prevent when travel switch is malfunctioning the recurring structure damage accident and keep self-locking, thereby reach the utility model purpose.

Fig. 2 is the A-A sectional drawing among Fig. 1.

Fig. 3 is the B-B sectional drawing among Fig. 1.

Fig. 4 is the utility model fluid power system schematic diagram.

Below in conjunction with accompanying drawing the utility model is further elaborated.

The utility model is made up of door body 1 and power-operated mechanism 2, door body 1 by framework 3, be evenly distributed in the railing 4 in the framework 3 and place the

roller

6,7 at 5 two ends, framework 3 bottoms to form, framework 3 and railing 4 are preferably square tube; Power-operated mechanism 2 is made up of fluid power system 8 and machine driven system 9, the variable pump 11 that fluid power system 8 has motor 10 and drives through motor 10, the oil-in 12 of variable pump 11 communicates with fuel tank 14 through oil filter 13, the oil-out 15 of variable pump 11 communicates with oil motor 17 through 3-position 4-way solenoid operated directional valve 16, the pressure meter 20 of overflow valve 19 is housed, the stop valve 21 that is equipped with in parallel on the oil circuit between 3-position 4-way solenoid operated directional valve 16 and the oil motor 17 on the oil circuit 18 between variable pump 11 and the 3-position 4-way solenoid operated directional valve 16; Machine driven system 9 is by the gear 23(or the sprocket wheel 24 that are contained on oil motor 17 output shafts 22) and with gear 23(or sprocket wheel 24) engagement tooth bar 25(or chain 26) form, tooth bar 25(or chain 26) be installed on framework 3 bottoms 5 of a body 1, fluid power system 8 is installed in the cavity 28 of door pillar 27.

In the time will opening the hydraulic levels moving door, starter motor 10, variable pump 11 is under the driving of motor 10, through oil filter 13, oil-in 12 is from fuel tank 14 oil suctions, and through oil-out 15 pressure oil output, handle 3-position 4-way solenoid operated directional valve 16, make it be in one, pressure oil enters the left oil port 29 of oil motor 17 through 3-position 4-way solenoid operated directional valve 16, the right oil port 30 of oil motor 17 communicates with fuel tank 14, oil motor 17 clockwise rotates, and gear 23(or sprocket wheel 24 on the drive output shaft 22) clockwise rotate, make tooth bar 25(or chain 26 with its engagement) move right, drive door body 1 through roller 6, the tracks 32 that 7 edges are embedded in the basis 31 move right, thereby gradually door body 1 are opened; When 3-position 4-way solenoid operated directional valve 16 was in two, left oil port 29, right oil port 30 were through 16 lockings of 3-position 4-way solenoid operated directional valve, and pressure oil is gone into fuel tank 14 16 times through the 3-position 4-way solenoid operated directional valve, and door body 1 is in opens back (or closing the back) self-locking state; When 3-position 4-way solenoid operated directional valve 16 was in three, pressure oil entered oil motor 17 through right oil port 30, and left oil port 29 communicates with fuel tank 14, make oil motor 17, gear 23(or sprocket wheel 24) rotate counterclockwise tooth bar 25(or chain 26) be moved to the left, thereby gradually door body 1 is closed.The just adjustable fuel-economizing motor 17 of the flow of regulated variable pump 11, gear 23(or sprocket wheel 24) and tooth bar 25(or chain 26) speed.

When the back variable pump 11 that has a power failure can not be worked, open stop valve 21, make hydraulic oil form loops through stop valve 21 and oil motor 17, but just manual-lock or open and open the hydraulic levels moving door.
