Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings. It should be understood that the detailed description is intended only to teach one skilled in the art how to practice the disclosure, and is not intended to be exhaustive or to limit the scope of the disclosure.
As shown in fig. 1 and 2, the present disclosure provides an elevator counterweight system that includes an elevator counterweight 1, a guide rail 6, a guide rail bracket 7, a safety gear 5, a speed governor 3, a tension device 4, and a lifting mechanism 2. Two guide rails 6 extending in the vertical direction are oppositely disposed in the hoistway, and the horizontal both ends of the elevator counterweight 1 are fitted to the two guide rails 6 so that the elevator counterweight 1 can move in the vertical direction along the guide rails 6. Two guide rail brackets 7 are located on both sides of the elevator counterweight 1 and are fixedly mounted to the hoistway wall 8, and the guide rails 6 are mounted to the guide rail brackets 7 so as to be supported by the guide rail brackets 7. The speed governor 3 is provided on one side of the elevator counterweight 1.
As shown in fig. 3, the governor 3 includes a governor wheel 31, a throw block 32, a rope holding block 33, a switch 34, a ratchet 35, a pawl 36, a bracket 37, and a wire rope 38 (shown in fig. 1) wound around the governor wheel 31, the governor wheel 31 is attached to the bracket 37, and the bracket 37 may be fixed to the guide rail 6 or the hoistway wall 8. The throwing block 32 and the speed governor wheel 31 rotate synchronously, and the throwing block 32 can move away from the circle center of the speed governor wheel 31 along the radial direction under the action of centrifugal force. When the rotation speed of the governor wheel 31 exceeds a set value, the thrower 32 triggers the pawl 36 to engage the ratchet wheel 35 to stop the rotation of the governor wheel 31 and drive the rope clamping block 33 to clamp the wire rope 38. For example, when the elevator counterweight 1 stalls and falls, the safety gear 5 stalls and falls together with the elevator counterweight 1, and at this time, the rope gripping block 33 grips the wire rope 38, and the wire rope 38 pulls the safety gear 5 to operate the safety gear 5 to stop the elevator counterweight 1.
It will be appreciated that the construction and operating principle of the governor 3 described above is conventional in the art and will only be briefly described here.
A guide rail bracket 7 (first guide rail bracket) located on the same side of the elevator counterweight 1 as the speed governor 3 is located between the horizontal ends of the speed governor 3. Preferably, the wire rope 38 is arranged on both horizontal sides of the guide rail bracket 7, i.e. in a horizontal plane (e.g. the plane of the drawing of fig. 2), the projection of this guide rail bracket 7 being located between the projections of the two opposite wire rope sections that pass around the governor wheel 31.
This makes full use of the space occupied by the rail brackets 7, and arranging the speed governor 3 near the rail brackets 7 without the rail brackets 7 exceeding the speed governor 3 in the horizontal direction can reduce the hoistway size occupied by the speed governor 3.
As shown in fig. 1, 4 and 5, the tension device 4 is located below the speed governor 3 and is disposed in the lower part of the hoistway, the tension device 4 has a tension pulley 41, a bracket 42, a pin 43, a monitor switch 44 and a counterweight 45, the tension pulley 41 and the counterweight 45 are mounted together, the counterweight 45 is fixed to one end of the pin 43, the other end of the pin 43 is rotatably mounted to the bracket 42, and the bracket 42 is fixed to the guide rail 6. The bracket 42, the weight block 45 and the tension wheel 41 are arranged in sequence along the axis of the tension wheel 41 (in the up-down direction in fig. 5), and the monitoring switch 44 is installed in the space between the bracket 42 and the weight block 45.
The weight 45 is located on one axial side of the tension wheel 41, and the weight 45 is located between the tension wheel 41 and the bracket 42, which makes the structure of the tension device 4 compact.
The tension pulley 41 is suspended on the wire rope 38 of the speed governor 3, and the weight of the counterweight 45 and the tension pulley 41 ensures that the wire rope 38 of the speed governor 3 is under tension. When the rope 38 is extended (for example, after the elevator counterweight system is used for a long time), the tension pulley 41 rotates around the pin 43, and the rope 38 is continuously in a tension state. When the rotation angle of the pin shaft 43 exceeds the set value, the monitoring switch 44 is operated to stop the elevator, so as to avoid the dangerous condition.
The counterweight 45 may not exceed the upper edge of the tension wheel 41 in the horizontal direction and the radial direction of the tension wheel 41, which further compresses the overall size of the tension device 4, thereby saving lateral space of the hoistway. And, the balancing weight 45 can be not lower than the tension wheel 41 in the up-down direction, which saves the longitudinal space of the shaft, thereby reducing the installation height of the tension device 4 and the depth of the pit.
As shown in fig. 6, the installation space between the elevator counterweight 1 and the shaft wall 8, specifically the space between the elevator counterweight 1 and the shaft wall 8 at the corner of the hoistway, in which installation space the speed limiter 3, the tensioning device 4 and the guide rail bracket 7 are provided, is shown in hatched areas.
The present disclosure optimizes the position of the components of the elevator counterweight 1 and compresses the dimensions of the components as much as possible, and makes full use of the area between the hoistway wall 8 and the elevator counterweight 1, enabling the elevator counterweight system to be set up with no or little increase in hoistway dimensions.
To this end, the present disclosure includes the following aspects in addition to the aspects described above.
For example, as shown in fig. 2, the elevator counterweight 1 has a near side portion 11 facing the elevator car and a far side portion 12 facing away from the elevator car, and the near side portion 11 and the far side portion 12 are arranged along the axis (in the up-down direction of fig. 2) of the governor sheave 31 (or the tension sheave 41), which makes the structure of the elevator counterweight system more compact.
Further, the governor sheave 31 and the tensioning sheave 41 are located on the far side of the elevator counterweight 1 from the elevator car, so that the governor 3 and the tensioning device 4 do not take up installation space of the elevator car.
As shown in fig. 1, 7 and 8, the lifting mechanism 2 is arranged below the elevator counterweight 1, and the safety gear 5 is arranged below the lifting mechanism 2, so that the transverse installation space of the elevator counterweight system is saved. The elevator counterweight system comprises two safety tongs 5, the two safety tongs 5 are arranged on two opposite sides of the center line of the elevator counterweight 1, and the two safety tongs 5 are respectively installed corresponding to the two guide rails 6 so as to be capable of respectively clamping the two guide rails 6.
The safety gear 5 comprises a base 51, a rod 52, a fixed ramp 53 and two wedges 54, which are mounted on the base 51, the rod 52 of the safety gear 5 being pulled by the cable 38 of the speed limiter 3 to pull the two wedges 54 up the fixed ramp 53 and gradually closer together until the two wedges 54 clamp the rail 6.
The lifting mechanism 2 comprises a rope head component 21, a lifting rod 26 and a linkage component, wherein the linkage component comprises two connecting plates 23, a connecting rod 24 and a connecting shaft 25. The connecting rod 24 has two ends connected to the connecting plates 23, the connecting plates 23 are connected to the connecting shaft 25 so as to be rotatable about the connecting shaft 25, and the connecting plates 23 are respectively connected to two safety gears 5 (for example, a rod 52 connected to the safety gears 5) and can pull a wedge 54 of the safety gears 5. The rope head assembly 21 is connected with two ends of a steel wire rope 38, the upper end of the lifting rod 26 is connected with the rope head assembly 21, and the lower end of the lifting rod 26 is connected with a connecting plate 23.
When the lifting rod 26 directly pulls the connecting plate 23 connected with the lifting rod, the other connecting plate 23 rotates around the connecting shaft 25 of the other connecting plate to realize synchronous movement of the wedge blocks 54 in the two safety gears 5, so that the linkage assembly transmits the lifting action of one lifting rod 26 on one connecting plate 23 to the other connecting plate 23, and the two safety gears 5 synchronously clamp the guide rail 6.
It should be understood that the structure and operation of the linkage assembly described above are well known in the art and will only be briefly described herein.
The connecting position of the rope head assembly 21 and the lifting rod 26 (the connecting position of the lifting rod 26 and the steel rope 38) is higher than that of the safety gear 5, so that the contact between the butt joint part of the steel rope 38 and the tensioning device 4 is avoided, and the pit depth is effectively reduced.
The linkage assembly may have a housing 22, which housing 22 forms a space for the attachment of the connection plate 23, the connecting rod 24 and the connecting shaft 25 and makes the linkage assembly an encapsulated whole, and which housing 22 may be connected with the base 51 of the safety gear 5 and with the lower part of the elevator counterweight 1.
Therefore, the linkage assembly can be integrally and additionally arranged below the elevator counterweight 1, and the installation process is simple.
In other embodiments, the housing 22 of the linkage assembly may additionally form a space for installing the safety gear 5, so that the safety gear 5 is integrally packaged in the housing 22 of the linkage assembly, which makes the integration degree of the elevator counterweight system higher.
It should be understood that the above-described embodiments are exemplary only, and are not intended to limit the present disclosure. Various modifications and alterations of the above-described embodiments may be made by those skilled in the art in light of the teachings of this disclosure, without departing from the scope of this disclosure.
