Definitions

  • the present invention relates to a compensation arrangement in an elevator as defined in the preamble of claim 1.
  • rope compensation There are two different types of rope compensation.
  • a rope, belt or chain can be used, and these can be lined with rubber or plastic and they often contain additional masses attached to them.
  • These ropes, belts or chains are mounted as loops below and between the car and counterweight and they are preferably attached to the lower parts of the car and counterweight.
  • the range of application of this rope compensation is limited to relatively low speeds because of the danger of swinging.
  • the speed of the rope, belt or chain is the same as that of the elevator. This speed occurring at the culmination point of the loop is called the loop circulation speed.
  • the speed of the elevator is changed during acceleration or deceleration, then the speed of the loop will be changed as well and the cable starts to swing. The larger the speed range, the greater is the danger that the swinging will result in the rope, belt or chain being caught on a piece of shaft equipment.
  • the additional masses used are generally a rope or ropes hanging in the form of loops below and between the car and counterweight.
  • these loops are tightened by means of a tensioning device.
  • the solution of the invention eliminates these drawbacks by rendering the expensive tension weight unnecessary and halving the loop speed as compared to the old loop.
  • This is achieved by suspending the compensating ropes so that they run from the underside of the elevator car to fixing points in the wall and, similarly, from the underside of the counterweight to fixing points in the shaft wall.
  • Both compensation loops are attached to the shaft wall at a point at or above the midpoint of the path of the elevator car or counterweight. When the car moves in the down direction, both the car cable loop and the compensation loop move downwards and the loop circulation speed is only half the travelling speed of the car.
  • the counterweight moves in the up direction and its compensation loop move upwards.
  • the circulation speed of the counterweight compensation loop is half the travelling speed of the counterweight.
  • Fig. 1 illustrates the structure of the solution of the invention. It shows an elevator 1 with an elevator car 2 suspended to a ratio of 1:1 and a counterweight 3 suspended by means of a diverting pulley 6 to a ratio of 1:1 , elevator ropes 11 supporting the elevator car 2 and counterweight 3, and a traction sheave 5 whose motion is transmitted via the ropes to the elevator car 2 and counterweight 3.
  • the car cable 4 is preferably passed from the car 2 to a fixing point 8 in a wall of the elevator shaft, and the compensation loop 7a is also passed from the car 2 to a fixing point 9 in a shaft wall.
  • the compensation loop 7b below the counterweight 3 is attached to a fixing point 10 in a shaft wall.
  • the compensation loops 7a and 7b are attached to the shaft wall at a point located at or above the midpoint of the path of the elevator car 2 or counterweight 3.
  • the point of attachment of the car cable 4 is at the same height as that of the compensation ropes.
  • the circulation speed of the compensation loop 7b for the counterweight 3 is half the travelling speed of the counterweight, and the circulation speed of the compensation loop 7a for the elevator car 2 is half the travelling speed of the car 2.
  • the loop length hanging from the elevator car 2 is at this point half the total loop length, i.e. about 1 ⁇ 4 of the travel height H.
  • the mass/measure of the car cable 4 is M2 and the mass/measure of compensation loop 7a is M3.
  • the coun terweight 3 contains the mass of the elevator car 2 + balanc ing percentage * nominal load + a so-called cable setoff .
  • Below the counterweight 3 hings the counterweight compensation loop 7b, in which the portion hanging from the counterweight 3 equals 1 ⁇ 4 of the travel height H.
  • the mass of this compensation loop, too, is M3/measure.
  • the bare weight of the elevator car 2 is P
  • the nominal load is Q
  • the counterweight balancing degree is T
  • X is an extra mass which is added to the counterweight 3 to achieve balance midway in the shaft.
  • Fig. 2 presents a situation where the car is near the top of the shaft and the counterweight is near the bottom.
  • Fig. 3 presents a situation where the car is near the bottom of the shaft and the counterweight is near the top.
  • Fig. 5 presents a solution which can be used in patents FI 82823.
  • the counterweight 3 is twice as heavy as in the above-mentioned figures 1-4 and the path and speed of the counterweight 3 are half those of the elevator car 2.
  • Fig. 5 shows the elevator car 2 in its extreme positions. The result in this case, too, is a fully compensated solution.
  • the mass/measure of the compensation loop 7b for the counterweight 3 is larger than the mass/measure of the compensation loop 7a for the elevator car 2.
  • the necessary equations can be solved by determining appropriate balancing equations for different solutions regarding the elevator car 2 and the counterweight 3. The equations depend on the location of the path of the counterweight 3, which may vary from case to case.
