detailed description of the invention:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
The elevator of a kind of adjustable counter-weight as shown in Figure 1 to Figure 3, described elevator comprises car 1 and counterweight 2, described car 1 and counterweight 2 are connected to the both sides of towing machine 4 by dragging chain 3, the first cavity 11 is provided with bottom described car 1, the second cavity 21 is provided with bottom described counterweight 2, oil pipe 5 is used to be tightly connected between described first cavity 11 and the second cavity 21, same liquid is injected in described first cavity 11 and the second cavity 21, described first cavity 11 inside is provided with first piston 12, described second cavity 21 inside is provided with the second piston 22, car 1 lower raft 8 is provided with control apparatus, described control apparatus comprises weighting apparatus 6, control box 7 and actuating device, described actuating device acts on first piston 12.After the quality of car 1 changes, mass change information is passed to control box 7 by weighting apparatus 6, the first situation is: the quality of car 1 increases N, the quality N that control box 7 increases according to car 1, accessory drive drives first piston 12 to move downward, the volume of the first cavity 11 reduces, and then by the Liquid transfer in the first cavity 11 in the second cavity 21, the effect that second cavity 21 is under pressure, promote the second piston 22 upward movement, so, the Mass lost N of car 1, the quality of counterweight 2 increases N, achieve car 1 to balance again with the quality of counterweight 2, the second situation is: the Mass lost of car 1, the quality N that control box 7 reduces according to car 1, accessory drive drives first piston 12 upward movement, and the volume of the first cavity 11 becomes large, under the effect of bar pressure, liquid in second cavity 21 is transported in the first cavity 11 by oil pipe 5, and the second piston 22 moves downward, and the volume of the second cavity 21 reduces, so, the Mass lost N of counterweight 2, the quality of car 1 increases N, and then achieves balancing again of car 1 and counterweight 2 quality.
Actuating device comprises motor 91, cross lead screw 92 and longitudinal screw mandrel 93, described motor 91 is fixedly mounted on base plate 8 bottom, described cross lead screw 92 one end is arranged on motor 91, the other end is arranged on bracing frame 94, described longitudinal screw mandrel 93 contacts mutually with cross lead screw 91 vertical cooperation, and described longitudinal screw mandrel 93 lower end is fixedly connected with first piston 12.Adopt mode that the longitudinal screw mandrel 93 of screw mandrel drives first piston 12 move more accurately, and vibrations in control process and noise less, be conducive to the smooth running of elevator.
The upper end of the second piston 22 is connected to the top of counterweight 2 by telescoping cylinder 10, telescoping cylinder 10 both play the guiding role to the second piston 22, the Action of Gravity Field that the second piston 22 is subject to can be overcome again, avoid the second piston 22 gravitate and move downward and affect whole device internal pressure balance.
First cavity 11 and the interior liquid injected of the second cavity 21 are hydraulic oil, and hydraulic oil plays in the process transmitted
energy transferring, wear-resistant, system lubrication,
anticorrosion,
antirust,
coolingdeng effect.
Because first piston 12 is subject to Action of Gravity Field, only by coordinating with cross lead screw 92 direct the gravity contacting and be not enough to overcome first piston 12 and be subject to, described longitudinal screw mandrel 93 upper end is connected with nut 932, spring 931 is provided with between described nut 932 and base plate 8, so, the elastic reaction of spring 931 balances the Action of Gravity Field of first piston 12, and 91, motor needs very little propulsive effort and adjustable first piston 12 to carry out up-and-down movement.
Longitudinal screw mandrel 93 has been arranged side by side four, avoids single longitudinal screw mandrel 93 and draws hypodynamic problem for first piston 12, make the security and stability of whole device stronger.
When elevator cars with full load, the volume of counterweight 2 internal liquid is greater than the volume of car 1 internal liquid, and therefore the variable volume of described second cavity 22 is greater than the variable volume of the first cavity 11.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
