Abstract
The utility model relates to an elevator counterweight device and belongs to the technical field of man ridding lifting devices. The device comprises a counterweight frame. A counterweight block is arranged in the counterweight frame. The top of the counterweight frame is fixedly connected with an upper connecting base. A support for supporting a horizontal shaft rope wheel is arranged above the upper connecting frame. The lower portion of the upper connecting base is fixedly connected with an upper end face gear base. The bottom of the support is fixedly connected with a stand column bolt which extends downwards. The lower end of the stand column bolt penetrates through the upper connecting base which forms movable fit with the stand column bolt and an upper end face gear base center hole and is fixedly connected with a lower end face gear base supported by a nut. The upper end face gear base and the lower end face gear base are provided with opposite end face gears respectively, and a partitioning spring is arranged between the upper end face gear base and the lower end face gear base. The structure is reasonable, the problem in the prior art is solved, rope wheel flexible operation can be kept, the phenomenon of blocking is avoided, and elevator operation safety is guaranteed.
Description
Technical field
The utility model relates to a kind of elevator assemblies, and especially a kind of elevator counterweight belongs to manned lift device technique field.
Background technology
Counterweight is the device for balance lift car.Conventionally counterweight is equipped with center of gyration and is supported in the rope sheave of counterweight frame top of the trellis.According to the applicant understood, existing counterweight positioned inside is to the counterweight frame top of the trellis of the pouring weight upper connecting base that is connected, and the supporting seat of support level axle rope sheave is settled in upper connecting base top; Between upper connecting base and supporting seat, be fixedly connected with by column bolt.Because the center of gyration of rope sheave is fixed with respect to the position of counterweight framework, therefore rope sheave only has rotary freedom, easily, because the factors such as the distortion in manufacture, installation error or use cause counterweight sheave and counterweight framework to be distorted,, even there is stuck phenomenon in not working when serious.
Utility model content
The purpose of this utility model is: the problem existing for above-mentioned prior art, by structural development, propose one and can automatically adjust strained condition in certain limit, thereby keep the elevator counterweight going slick, stop stuck phenomenon, guarantee lift running safety.
In order to achieve the above object, elevator counterweight of the present utility model comprises the counterweight framework of positioned inside to pouring weight, the top of the described counterweight framework upper connecting base that is connected, and the supporting seat of support level axle rope sheave is settled in described upper connecting base top; Described upper connecting base bottom is fixedly connected with upper surface pinion stand, and the bottom of described supporting seat is fixedly connected with the column bolt towards downward-extension; The lower end of described column bolt is through forming with it moving upper connecting base and the upper surface pinion stand centre hole coordinating, the lower surface pinion stand that is connected and is held by lower end nut; Described upper surface pinion stand has respectively relative end-tooth with lower surface pinion stand, and spacer spring is housed each other.
Like this, when rope sheave is during in non-lifting state, upper surface pinion stand and lower surface pinion stand under the effect of spacer spring in non-engagement state, rope sheave is except the horizontal rotational shaft degree of freedom of self, also due to column bolt and the moving indexable degree of freedom with vertical axle that coordinates of upper connecting base and upper surface pinion stand centre hole.In the time that rope sheave lifts by crane, first the vertical axle of automatic winding is adjusted and the angular position of counterweight framework, afterwards the weight of pouring weight will be overcome to the application force of spacer spring, make the end-tooth of upper and lower end face pinion stand intermeshing, retrain the degree of freedom around vertical axle transposition, thereby make counterweight trouble-free operation under the state of distortionless power.
Obviously, the utility model has overcome with rational structural development the problem that prior art exists, and can keep rope sheave to go slick, and stops stuck phenomenon, guarantees lift running safety.
The utility model further improves, and the cross section of described upper connecting base is downward opening channel-section steel shape, and bottom is fixedly connected with upper surface pinion stand, forms square shape cross section structure.
It is that the envelope external diameter of described upper surface pinion stand and lower surface pinion stand is greater than the envelope external diameter of lower end nut that the utility model further improves.
It is that described column bolt circumferentially retrains by radially interspersed locating dowel pin and lower end nut that the utility model further improves.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Embodiment mono-
As depicted in figs. 1 and 2, one group of counterweight framework 1 positioned inside of square-section is to pouring weight 2 for the elevator counterweight of the present embodiment, the top of this counterweight framework upper connecting base 3 that is connected, and the supporting seat 5 of support level axle rope sheaves 4 is settled in upper connecting base 3 tops.
As shown in Figure 2, the cross section of upper connecting base 3 is downward opening channel-section steel shape, and bottom is fixedly connected with upper surface pinion stand 6, the square shape cross section structure of complete, and the bottom of supporting seat 5 is fixedly connected with the column bolt 9 towards downward-extension.The lower end of this column bolt is through forming with it the moving upper connecting base 3 coordinating and the centre hole of upper surface pinion stand 6, and lower end has screwed lower end nut 11, and circumferentially retrains by radially interspersed locating dowel pin 10 and lower end nut 11, prevents from becoming flexible.On lower end nut 11, hold the lower surface pinion stand 7 being connected with it.Upper surface pinion stand 6 has respectively relative end-tooth with lower surface pinion stand 7, and spacer spring 12 is housed each other.The envelope external diameter of upper surface pinion stand 6 and lower surface pinion stand 7 is greater than the envelope external diameter of lower end nut 11, therefore has better load bearing effect, contributes to guarantee the stability of counterweight in operational process.
The utility model has overcome with rational structural development the problem that prior art exists, and can keep rope sheave to go slick, and stops stuck phenomenon, guarantees lift running safety.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
