Description

A kind of adjustable counter balance lifting device
Technical field
The utility model belongs to building hoist technical field, and in particular to a kind of adjustable counter balance lifting device.
Background technique
In current most of elevator structures, unique driving part is only a traction motor, due to this Class drum elevator lacks corresponding torque balance device, therefore in the process of running, bears required for entire traction motor Workload it is very huge, it is following, be exactly whole system power consumption is very big, operational efficiency is low.
And in order to overcome drawbacks described above, there are also be provided on elevator for equalising torque to pouring weight at present.Out It is this kind of that pouring weight generally can all be carried when weight selects with the maximum of elevator when being run to elevator the considerations of extreme case Lotus is as a comparative reference, so, larger to the weight of pouring weight side when the load of elevator is not up to maximum value, power Square is still within imbalance state, and there is still a need for bear biggish load for traction motor.It is understood that using this set side Formula, the problem that whole system power consumption is larger, operational efficiency is low are not solved at all.
Therefore, it is very crucial for researching and developing a kind of adjustable counter balance lifting device for being able to solve the above problem.
Summary of the invention
The purpose of this utility model is to provide a kind of adjustable counter balance lifting devices.
The purpose of this utility model is achieved in that including bracket, driven sheave, rope, the support vertical installation In ground, the top of bracket is provided with traction platform, and traction platform includes rope sheave guide plate arranged in parallel and stretches Push rod, the rope sheave are set between rope sheave guide plate and telescopic putter, and rope sheave wheel shaft one end and the side of telescopic putter connect It connecing, the other end and the sliding slot of rope sheave guide plate side are slidably matched, traction machine is provided on traction platform, the traction machine Power output shaft is connected with rim pulley, and rim pulley is corresponding with driven sheave, and one end of the rope connects hanging basket, another Successively through rim pulley, driven sheave and match reconnection in end.
Compared with prior art, the utility model has following technical effect that
1, the utility model realizes the balance to the moment of load in elevator structure by the setting of balance weight mechanism, effectively The workload for reducing traction motor reduces the power consumption of entire elevator system.
2, the counterweight in the utility model can also constantly convert Balance weight end according to the different load condition of elevator Torque further reduced traction electricity so that mechanism realizes the balance to the various load weights of elevator by quantitative counterweight The workload of machine improves the operational efficiency of elevator entirety.
3, the utility model increases the payload ratings of crane by using adjustable counterweight, makes its working efficiency It is higher.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model;
Fig. 2 is Fig. 1 traction platform schematic perspective view;
In figure: 1- traction machine, 2- traction platform, 21- rope sheave track, 22- telescopic putter, 3- rope, 4- hanging basket, 5- buffering Bed course, the ground 6-, 7- driven sheave, 8- counterweight, 9- bracket, 10- rim pulley.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings, but is not subject in any way to the utility model Limitation is transformed or replaced based on any made by the utility model introduction, belongs to the protection scope of the utility model.
The utility model as shown in 1 ~ Fig. 2 of attached drawing includes bracket 9, driven sheave 7, rope 3,9 right angle setting of bracket In ground 6, the top of bracket 9 is provided with traction platform 2, traction platform 2 include rope sheave guide plate arranged in parallel and Telescopic putter, the rope sheave 7 are set between rope sheave guide plate 21 and telescopic putter 22, and 7 wheel shaft one end of rope sheave is pushed away with flexible The side of bar 22 connects, and the other end and the sliding slot of 21 side of rope sheave guide plate are slidably matched, and is provided with traction machine on traction platform 2 1, the power output shaft of the traction machine 1 is connected with rim pulley 10, and rim pulley 10 is corresponding with driven sheave 7, described One end of rope 3 connects hanging basket 4, and the other end is successively connect through rim pulley 10, driven sheave 7 with counterweight 8.
Cushion 5 is provided with below the hanging basket 4.
The telescopic putter 22 includes electric pushrod and electric drive hydraulic thruster.
The weight of the counterweight 8 is 4 empty-weight of hanging basket to 4 half loading capacity of hanging basket.
The rope 3 is cable wire.
The traction platform 2 is to be horizontally installed to cantilever tip.
The rope 3 is connect by hanging ring with hanging basket 4.
The counterweight 8 is cylindrical, and side is equipped with chuck 12, and 8 side of counterweight is arranged with counterweight ring 11, and matches Weight ring 11 is blocked by chuck 12, and the counterweight ring 11 is semicircular ring, and the side of the counterweight ring 11 is equipped with bolt hole, bolt Hole is equipped with fastening bolt 13.
Utility model works principle and the course of work:
Operator can operate electric drive hydraulic thruster 22 and stretch, make to be fixedly connected with push rod according to lifting end moment Rope sheave 7 moved on rope sheave track 21, with achieve the purpose that change counterweight end moment.When lifting end is unloaded or load is small, Lifting end moment < counterweight end moment, control counterweight 8 is mobile to bracket 9, when lifting end when overloaded, lifting end moment > Balance weight end Torque, control counterweight 8 is mobile to the direction far from bracket 9, to keep lifting end moment=counterweight end moment as far as possible, reduces and drags The workload for drawing motor 1 improves elevator overall operation efficiency.
