Distance A: Distance between the center a of the counterweight 4 and the front center of the front end of the weight rail 5A. P: The torsional torque during the earthquake, ie, when the load acts on the counterweight 4 The working load p and the enemy PA of distance A are the major factors in determining the rail structure of one row.
이때 추용레일(5A)의 선단중심(b)은 제6도에 표시한대로 레일저면에 가까운 위치에 있으므로 비틀림토크 PA치는 크게되며 추용레일(5A)은 이에 견디게하기위하여 큰레일소재가 요구되는 문제점이 있다.At this time, the tip center (b) of the traction rail (5A) is close to the bottom of the rail as shown in FIG. 6, so the torsion torque PA is large, and the traction rail (5A) requires a large rail material to withstand it. have.
또 거리 H 및 폭 L가 규정된경우 소요의 중량을 얻기위하여는 균형추(4)의 높이를 높게하지않으면 않되며 설치상 지장을 초래하는 문제점도 있다.In addition, if the distance H and the width L is prescribed, in order to obtain the required weight, the height of the counterweight 4 must be high and there is a problem that causes installation problems.
본 고안은 상기 문제점을 해결하기위한것으로서 추용레일의 재료를 삭감하여 충분히 비틀림토크에 견딜수있으며 또한 설치공간이 규정된 경우라도 균형추의 높이가 높게 되는것을 방지할수 있도록한 엘리베이터의 균형추장치를 제공함을 목적으로 한다.The present invention aims to provide an elevator counterweight device that can withstand the torsional torque sufficiently by reducing the material of the induction rail and to prevent the height of the counterweight from becoming high even if the installation space is defined. It is done.
본 고안에 관한 엘레베이터의 균형추장치는 추의 주행을 안내하는 돌출부가 있는 한가닥의 긴부재에 의하여 추용레일을 구성하고 균형추의 추용레일과의 대향부에 요부를 형성하여 이요부내에 추용레일의 돌출부를 삽입시킨 것이다.The elevator counterweight device according to the present invention constitutes a weight rail by a long member of a strand having a protrusion for guiding the running of the weight, and forms a recess in an opposite portion to the weight rail of the weight weight, thereby forming a protrusion of the weight rail in the yo-yo. It is inserted.
본 고안에 있어서는 추용레일의 선단중심은 추용레일의 상면측에 있으며 또한 균형추의 중심은 제6도의 중심(a)보다도 추용레일측에 위치하므로 비틀림토크 PA는 작아진다.In the present invention, the tip center of the traction rail is located on the upper surface side of the traction rail, and the center of the balance weight is located on the traction rail side rather than the center (a) of FIG.
제1도-제4도는 본 고안의 일실시예를 표시하는 도면으로 제1도는 승강로 횡단면도, 제2도는 요부확대단면도, 제3도는 균형추의 사시도, 제4도는 작용설명도이며, 1, 2, 3A, 3B는 상기 종래장치와 같은 것이다.1 to 4 are diagrams showing an embodiment of the present invention, in which FIG. 1 is a cross-sectional view of a hoistway, FIG. 2 is an enlarged cross-sectional view of a main part, FIG. 3 is a perspective view of a balance weight, and FIG. 3A and 3B are the same as the conventional apparatus.
도면중 7은 카(2)의 측방에 배치된 균형추로 프레임(8)에 다수의 추(9)를 적층한것으로 되어있으며 추(9)의 승강로(1)벽측의 중앙부에는 요부(9a)가 형성되어 있다.In the figure, 7 is formed by stacking a plurality of weights 9 on the frame 8 with a balance weight arranged on the side of the car 2, and a recessed portion 9a is formed at the center of the wall of the hoistway 1 of the weight 9. It is.
10은 프레임(8)의 상하단면에 고정되어 일단이 요부(9a)를 사이에 두고 서로 대향배치된 고정구, 11은 고정구(10)의 일단에 설치되고 홈으로 형성된 안내슈우, 12은 승강로(1)의 벽에 따라 수직설치된 횡단면이 π자형의 간판재로된 추용레일이며, 12a는 일부가 안내슈우(11)와 계합되며, 홈(12b)이 형성된 돌출부, 13은 카용레일(3A)의 배면과 추용레일(12)의 배면을 레일파지구(14)로 결합하는 공용고정구, 15는 승강로(1)의 벽에 고정되어 공용정구(14)에 용접된 카측지지구, 16은 마찬가지로 추측지지구, 17은 카용레일(3B)의 배면에 결합된 고정구, 18은 승강로(1)의 벽에 고정되어 고정구(17)에 용접된 지지구이다.10 is fixed to the upper and lower end surface of the frame 8, one end of which is disposed opposite to each other with the recessed portion (9a) between, 11 is a guide shoe installed in one end of the fixture 10 and formed into a groove, 12 is the hoistway (1) The cross-section vertically installed along the wall of) is an umbilical rail with a π-shaped signboard, 12a is partly engaged with the guide shoe 11, a protrusion formed with a groove 12b, and 13 is a rear surface of the car rail 3A. And a common fixture for coupling the rear surface of the additional rail 12 to the rail gripper 14, 15 is a car side support fixed to the wall of the hoistway 1 and welded to the common fixture 14, and 16 is a similarly supported support. , 17 is a fixture coupled to the rear surface of the car rail 3B, 18 is a fixture fixed to the wall of the hoistway 1 and welded to the fixture 17.
상기와 같이 구성된 엘리베터의 균형추장치에 있어서는 추용레일(12)의 횡단면은 승강로(1)의 측벽에 개구하는 개구단면을 형성하고 돌출부(12a)가 균형추(7)의 요부(9a)에 삽입되어 그 일부가 안내슈우(11)와 걸어 맞추어져있다.In the above-described elevator counterweight device, the transverse cross section of the weight rail 12 forms an opening cross section opening on the side wall of the hoistway 1, and the protrusion 12a is inserted into the recess 9a of the counterweight 7. Part of it is engaged with the guide shoe 11.
이와같이하여 균형추(7)의 승강은 원활히 안내된다.In this way, the lifting and lowering of the counterweight 7 is smoothly guided.
이경우 추용레일(12)의 전단중심(b)은 제4도에 표시한 바와같이 개구반대측에 위치한다.In this case, the shear center b of the weighting rail 12 is located on the opposite side of the opening as shown in FIG.
또 거리 H 및 폭 L가 규정된 경우 균형추(7)의 중심(C)은 제6도의 경우의 중심(a)보다도 요부(9a)측에 위치한다.In the case where the distance H and the width L are defined, the center C of the counterweight 7 is located on the recess 9a side rather than the center a in the case of FIG.
따라서 비틀림토크 PA치는 제6도의 경우보다도 작게할수있어 비틀림에 의한 응력 및 휘는것을 경감할수가 있다.Therefore, the torsion torque PA value can be made smaller than in the case of FIG. 6, thereby reducing stress and warping caused by torsion.
이에따랄 추용레일(12)의 재료를 삭감하여 소요의 성능을 발휘 시킬수 있게 된다.Accordingly, it is possible to exhibit the required performance by reducing the material of the additional rail 12.
또 거리 H 및 폭 L가 규정된 경우 균형추(7)의 양측부의 중심깊이 B를 크게하여 투영면적을 크게할수 있으므로 소요중량을 얻는데 균형추(7)의 높이를 낮게할수가 있다.In addition, when the distance H and the width L are defined, the center depth B of both sides of the counterweight 7 can be increased to increase the projected area, so that the height of the counterweight 7 can be lowered to obtain the required weight.
이상 설명한바와같이 본 고안에서는 추의 주행을 안내하는 돌출부가 있는 한줄의 긴 부재에 의하여 추용레일이 구성되고 이 균형추의 추용레일과의 대향부에 요부를 형성하며 이요부내에 추용레일의 돌출부를 삽입하여 안내 슈우에 걸어맞추었으므로 추용레일의 재료를 삭감하여 충분히 지지시의 비틀림토크에 견딜수있는것을 얻을수있으며 또한 균형추의 높이를 낮게 하여 승강로공간의 유효이용을 도모할수있는 효과가 있다.As described above, in the present invention, the weight rail is constituted by a single row of long members having protrusions for guiding the running of the weight, and the recess is formed at the opposite side to the weight rail of the counterweight, and the protrusion of the weight rail is inserted into the recess. It is possible to achieve the effective use of the space of the hoistway by lowering the height of the counterweight by reducing the material of the traction rail so that it can fully withstand the torsional torque when it is supported.
