Description
Technical Field
The invention relates to the technical field of elevators, in particular to an elevator which has a large distance between the center of an elevator car and the center of a counterweight due to special design and the like and needs a compensation system, and discloses a traction type vertical elevator compensation system which can solve the problem that the traditional compensation system causes unbalanced load of the elevator car and improves the running quality of the elevator.
Background
In general, when the elevator stroke exceeds 30m, a compensation chain (a rope or a cable) is attached to the car and the counterweight in order to balance the weight of the hoisting rope (the compensation chain will be described as an example).
In the common elevator compensation system as shown in fig. 1 and 2, when the center of the elevator car 1 is far from the center of the counterweight 2 (see fig. 2), the car side cannot be installed at a position close to the center of the elevator car 1 in order to ensure that the compensation chain 3 is in a vertical state during the operation of the elevator due to the characteristic that the compensation chain 3 has the maximum bending diameter, and can only be designed to be as close to the center of the elevator car 1 as possible according to the maximum bending diameter of the compensation chain 3; thus, the compensating chain 3 generates a unbalanced load force on the car 1, and the longer the elevator is, the greater the unbalanced load force is generated as the length of the compensating chain 3 on the car side is; when the unbalanced load exceeds the bearing capacity of the car guide, the running quality of the car 1 is affected. To solve this problem, a counterweight 4 is usually added to the car 1 to balance the unbalanced load force of the compensating chain 3 on the car 1; however, the added balance weights 4 are constant force and cannot be changed due to different positions of the lift car 1 in a well; the offset load force generated by the compensation chain 3 on the car 1 increases along with the position rise of the car 1; thus, the number of the balance weights 4 to be added to the car and the positions of the balance weights to be added to the bottom of the car all take a long time for on-site debugging personnel to debug.
Disclosure of Invention
The technical problem to be solved by the invention is to provide a traction type vertical elevator compensation system for solving the problems.
The technical problems to be solved by the invention can be realized by the following technical scheme:
The traction type vertical elevator compensation system comprises a car side compensation system and a counterweight side compensation system, wherein the car side compensation system comprises a car side compensation chain, one end of the car side compensation chain is fixed at the bottom of a car, the other end of the car side compensation chain is fixed on a hoistway wall or a guide rail, and the installation height is a position of adding 2m upwards after half of the elevator stroke; the counterweight side compensation system comprises a pair of counterweight side compensation chains, one end of each counterweight side compensation chain is fixed at the bottom of the counterweight, the other end of each counterweight side compensation chain is fixed on a hoistway wall or a guide rail, and the installation height is half of the stroke of the elevator and is increased by 2 m.
In a preferred embodiment of the present invention, one end of the car-side compensation chain is fixed to the bottom of the car as close to the center of the car as possible; one end of the counterweight side compensation chain is fixed at the bottom of the counterweight and is as close to the center of the counterweight as possible.
Due to the adoption of the technical scheme, the traction type vertical elevator compensation system realizes balance of the weight of the traction steel wire rope, and eliminates or reduces unbalanced load force of the compensation system on the elevator car, so that the running quality of the elevator car is improved; and the balance weight is cancelled, and the working hours of installing and debugging the balance weight are reduced.

Detailed Description
The invention is further described below with reference to the drawings and detailed description.
In fig. 1 to 4, 5 is a car diverting sheave, 6 is a traction sheave, 7 is a machine room guide sheave, 8 is a traction wire rope, and 9 is a counterweight diverting sheave.
Referring to fig. 3 and 4, the traction type vertical elevator compensating system shown in the drawing with a traction ratio of 2:1 includes a car side compensating system and a counterweight side compensating system.
The car-side compensation system comprises a car-side compensation chain 10, one end of which car-side compensation chain 10 is fixed to the bottom of the car 1, as close as possible to the center of the car 1, considering the limitation of the bending diameter of the car-side compensation chain 10, and in particular, four mounting points 11, 12, 13, 14 (of course, but not limited to these four mounting points) may be suitable when one end of the car-side compensation chain 10 is fixed to the bottom of the car 1, but these four mounting points 11, 12, 13, 14 are relatively close to the center 15 of the car 1, and one end of the car-side compensation chain 10 may be fixed to these four mounting points 11, 12, 13, 14, although other mounting points close to the center 15 of the car 1 may be fixed. The other end of the car-side compensation chain 10 is fixed on the hoistway wall or the guide rail 30, and the installation height is half of the elevator travel and is increased by 2m, so that when the car 1 moves to the highest level, the car-side compensation chain 10 installed on the hoistway wall or the guide rail has a vertical section of more than 1m, and the car-side compensation chain 10 is convenient to bend.
The counterweight-side compensation system includes a pair of counterweight-side compensation chains 20, and one end of the counterweight-side compensation chain 20 is fixed to the bottom of the counterweight 2 as close to the center of the counterweight 2 as possible, considering being limited by the bending diameter of the counterweight-side compensation chains 20. The counterweight-side compensation chain 20 may have two mounting points 21, 22 (of course, not limited to these two mounting points) when one end is fixed to the bottom of the counterweight 2, but these two mounting points 21, 22 are relatively close to the center 23 of the counterweight 2, and one end of the counterweight-side compensation chain 20 may be fixed to these two mounting points 21, 22, or may be fixed to other mounting points close to the center 23 of the counterweight 2. The other end of the counterweight-side compensation chain 20 is fixed on the hoistway wall or the guide rail 30, and the installation height is half of the elevator travel and is increased by 2m, so that when the counterweight 2 runs to the highest level, the counterweight-side compensation chain 20 installed on the hoistway wall or the guide rail has a vertical section of more than 1m, and the counterweight-side compensation chain 20 is convenient to bend.
The traction type vertical elevator compensation system of the invention can also be used for traction type vertical elevators with other traction ratios.
