Abstract
The utility model relates to a hydraulic counterweight lifting stage, which is characterized in that one end of a flexible drag rope is fixed to the hydraulic counterweight lifting stage, and the other end of the flexible drag rope is fixed to a push rod of a hydraulic counterweight oil cylinder set; a screw rod is driven by a driving motor to be meshed with a screw nut which is directly fixed to the hydraulic counterweight lifting stage, the driving motor together with he hydraulic counterweight oil cylinder set pulls the flexible drag rope to form a lifting stage. The utility model adopts a hydraulic counterweight as the main balanced force of the lifting stage, realizes the long-distance control of the lifting stage through an oil circuit, and reduces the power demands of the driving motor. The utility model has the advantages of simple structure, stable stage operation, and easy lifting speed control, and is a novel lifting stage at present.
Description
The utility model relates to stage machinery, especially a kind of hydraulic counterweight elevator stage.
In elevator stage machinery, in order to reduce motor-driven power, stage is operated steadily, often in stage machinery, be added with counter weight device.In the prior art, what generally adopt is the mechanical type counterweight, and promptly the end at the lifting flexible cable is fixed with a counterweight by pulley.The hole is excessive because the mechanical type counterweight causes under the platform machine, and the operation of the rising or falling speed of counterweight is not steady, and rising or falling speed is wayward, and can not realize long distance control.
The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of simple in structure, and stage operates steadily and can realize the hydraulic counterweight elevator stage that long distance is controlled.
The purpose of this utility model is achieved in that
The other end that one end installs flexible cable before the lights is packed on the push rod of hydraulic counterweight oil cylinder group, and drive motors drives leading screw and meshes screw and the common elevator stage of oil cylinder group traction flexible cable that directly installs before the lights.
Described drive motors drives power transmission shaft and drives leading screw by bevel gear by driving-belt; What the lifting of described flexible cable traction stage was passed through is pulley; Described hydraulic counterweight oil cylinder group is that the several of symmetrical setting carry out the fluid power transmission to oil cylinder by a hydraulic counterweight; Oil cylinder group, drive motors, bevel gear are installed under the platform in the machine hole, and described flexible cable is a chain.
Advantage of the present utility model and good effect are:
By adopting the equilibrant force of hydraulic counterweight as main elevator stage, and hydraulic power operates steadily, and can realize long distance control to stage by oil circuit; Can carry out the reliable control of rising or falling speed by choke valve; The driving force ratio of drive motors driving leading screw is less, has reduced the power requirement of motor; Hydraulic counterweight oil cylinder group can effectively reduce taking up room that machine is cheated under the platform.The utility model is simple in structure, and stage operates steadily and rising or falling speed is easy to control, is present a kind of novel elevator stage.
Description of drawings:
Fig. 1 is a structural front view of the present utility model;
Fig. 2 is the structural representation of machine hole transmission device under Fig. 1 platform.
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
Flexible cable 6 one ends are packed on the stage 4, the other end by pulley 5, pulley 9, be packed on the push rod 11 of oil cylinder 10.Generally speaking, form the oil cylinder group by two oil cylinders, its cantilever arm installs a push rod jointly, to common stage, need a few group oil cylinder groups, and each oil cylinder group balanced configuration, can be that several flexible cables draw stage jointly, in the present embodiment, only example a pair of symmetrical oil cylinder group and two flexible cables.This is to there being a drive motors 12 between the oil cylinder group, this drive motors drives the drive 15 of the power transmission shaft 13 that is packed in both sides by conveyer belt 16, this is symmetrical arranged and meshes respectively the bevel gear 14 at two ends to power transmission shaft, bevel gear upwards meshes the leading screw 2 with 3 engagements of stage screw.
Oil cylinder group, drive motors, bevel gear are installed under the platform in the machine hole, promptly below the stage between the support 1.Thereby hydraulic counterweight 7 is to carry out hydraulic power by the counterweight own wt through 8 pairs of oil cylinder groups of oil circuit to realize the pulling force of oil cylinder group push rod to flexible cable.In the present embodiment, flexible cable is a chain, also can be other flexible tension rope.
The operating principle of present embodiment is:
Hydraulic counterweight can be placed under the platform in the machine hole, also can be placed on the place that any one is convenient to operation, thereby realizes long distance control.Hydraulic counterweight is adjusted by choke valve (present embodiment is not shown) and is acted on the oil cylinder group by oil circuit.Installed flexible cable (chain) on the push rod of oil cylinder group, can balance most of weight of stage by hydraulic counterweight, drive motors drives the drive that is packed on the power transmission shaft by driving-belt, drive drives power transmission shaft and passes through the bevel gear engagement leading screw at its two ends, the screw that leading screw engagement stage installs is realized the balance of drive motors to a small amount of weight of stage or load.Like this, be major impetus by hydraulic counterweight oil circuit transmission fluid masterpiece, have operate steadily, advantage that long distance control, speed are easy to grasp, and because a small amount of weight of stage or load ratio are less, therefore the power of the drive motors that adopts can be very little.
Claims (5)
1. hydraulic counterweight elevator stage, constitute by stage, flexible cable, drive motors, leading screw, it is characterized in that: the other end that an end installs flexible cable before the lights is packed on the push rod of hydraulic counterweight oil cylinder group, and drive motors drives leading screw and meshes screw and the common elevator stage of oil cylinder group traction flexible cable that directly installs before the lights.
