Description

엘리베이터 완충장치의 오일받이장치Oil sump of elevator shock absorber

제1도는 종래 완충기의 일부 단면도.1 is a partial cross-sectional view of a conventional shock absorber.

제2도는 본 고안 완충기의 일부 정단면도.2 is a partial front cross-sectional view of the shock absorber of the present invention.

제3도는 본 고안 완충기 평면도.3 is a plan view of the present invention buffer.

제4도는 본 고안 완충기 일부 단면 사시도.4 is a partial cross-sectional perspective view of the present invention shock absorber.

본 고안은 엘리베이터에 있어서 로우프의 절단 또는 그외의 원인으로 케이지 또는 카운터 웨이트(C.WT)가 낙하할때의 충격을 흡수하여 완전히 정지시키는 완충기에 있어서 완충기의 오일을 보전 및 관리하는 것으로 플런져와 부시의 기밀유지를 위해 오일을 공급하는데 있어 오일의 공급회수를 줄이며 오일의 낭비를 방지하고 바닥의 청결유지가 용이하도록 부시 및 오일받이를 형성한 것이 본 고안의 목적이다.The present invention conserves and manages the oil in the shock absorber in the shock absorber that absorbs the shock when the cage or counterweight (C.WT) falls due to the cutting of the rope or other causes in the elevator. It is an object of the present invention to reduce the number of times the oil is supplied in the oil supply for maintaining the airtightness of the bush, to prevent the waste of oil, and to form the bush and the oil pan so as to keep the bottom clean.

종래 케이지 또는 카운터 웨이트가 낙하할때 완충기의 플런져에 충격하중이 가해지고 플런져는 부시와 기밀이 유지되므로 실린더내의 오일에 압력이 전달되어 오일은 압축을 받게되며 이 압축된 오일은 오리피스와 로드의 틈새를 통해 플런져내로 유입됨에 따라 플런져는 서서히 하강하겠끔 되어 있으므로 여기서 플런져와 부시와의 기밀유지를 위해 항상 오일막을 형성하여야 되는데 종래에 있어서는 주기적으로 플런져의 표면에 오일을 공급하여야 하며 또한 오일 공급시 플런져의 표면을 따라 흘러내려오는 오일은 부시 및 실린더의 표면을 따라 흘러내려 바닥에 고이게 됨에 따라 오일의 낭비 및 바닥의 청결 유지가 곤란하였던 것이다.When the cage or counter weight falls, the shock load is applied to the plunger of the shock absorber and the plunger is kept tight with the bush. Therefore, pressure is transmitted to the oil in the cylinder, and the oil is compressed. As the plunger is to be gradually lowered as it flows into the plunger through the gap of, the oil film must always be formed to maintain the airtightness between the plunger and the bush. In the conventional art, oil must be supplied periodically to the surface of the plunger. In addition, the oil flowing along the surface of the plunger during the oil supply flows down the surface of the bush and the cylinder and collects on the floor, which makes it difficult to waste oil and maintain the floor clean.

이와 같이 본 고안은 종래의 결점을 해소하기 위해 종래 완충기의 부시를 개선하고 오일 받이를 형성한 것으로 오일의 공급회수를 줄이며 오일의 낭비를 방지하고 바닥의 청결유지를 용이하게 한 것으로 본고안을 첨부된 도면에 의하여 구체적으로 그 구성 및 작용효과를 설명하면 다음과 같다.As such, the present invention improved the bush of the conventional shock absorber and formed the oil receiver in order to solve the conventional drawbacks, which reduces the number of times of supply of oil, prevents waste of oil, and facilitates cleanliness of the floor. Referring to the configuration and operation effects in detail as shown in the drawings as follows.

완충기(1)의 고무판(2)과 완충기(1) 상부덮개(3)를 고정볼트(4)로 프런저(5) 상부에 고정하고 부시(6)를 고정볼트(7)로 실린더(9)와 체결하며 플런저(5) 하단부와 부시(6) 하단부턱에 오리피스(8)를 끼워 맞춤하고 실린더(9) 내에 프런저(5) 복귀스프링(10)을 개재하며 실린더(9) 내의 완충기 하부판(11) 중심에 로드(12)를 형성한 완충기(1)에 있어서, 부시(6) 일측에 오일 유입홀(20)과 오일배출홀(21)을 형성하고 부시(6)와 프런저(5)가 삽입되어 형성된 요홈(22)에 걸이구(23)를 가진 오일저장통(24)을 걸이구(23)를 이용하여 요홈(22)에 걸어 프런져(5) 원통표면을 따라 흘러내린 오일이 오일저장홀(가)을 채우고 난후 부시(6)에 형성된 오일유입홀(20)과 오일 배출홀(21)을 따라 저장통(24)으로 흘러들어오게 구성한 것이다.The rubber plate (2) of the shock absorber (1) and the upper cover (3) of the shock absorber (1) are fixed to the upper part of the plunger (5) with the fixing bolt (4), and the bush (6) with the fixing bolt (7) to the cylinder (9). And the orifice 8 at the lower end of the plunger 5 and the lower end of the bush 6, and the buffer lower plate in the cylinder 9 with the plunger 5 return spring 10 interposed therebetween. 11) In the shock absorber 1 having the rod 12 formed in the center, the oil inlet hole 20 and the oil outlet hole 21 are formed at one side of the bush 6, and the bush 6 and the plunger 5 are formed. Oil flows along the cylindrical surface of the plunger (5) by hooking the oil reservoir (24) having the hook (23) to the groove (22) formed by the hook (23). After filling the storage hole (a) is configured to flow into the reservoir 24 along the oil inlet hole 20 and the oil discharge hole 21 formed in the bush (6).

이와 같이 된 본 고안은 제 2 도에서 플런져(5)와 부시(6)의 기밀유지를 위한 오일의 공급에 있어서 플런져(5)의 원통표면에 오일을 공급하면 플런져(5)의 원통 표면을 따라 흘러내려 부시(5)에 형성되어 있는 요홈(22)에 모인다음 오일의 유입홀(20)을 따라 오일저장홀(가)로 흘러들어와 저장된다. 이때 오일저장홀(가)를 채우고난 여분의 오일은 오일배출홀(21)을 따라 오일받이저장통(24)로 흘러들어와 저장된다.The present invention as described above, in the supply of oil for the airtight maintenance of the plunger 5 and the bush 6 in FIG. 2, when the oil is supplied to the cylindrical surface of the plunger 5, the cylinder of the plunger 5 It flows along the surface and collects in the grooves 22 formed in the bush 5, and then flows into the oil storage hole A along the inflow hole 20 of the oil and is stored therein. At this time, the excess oil filled in the oil storage hole (a) flows into the oil receiving reservoir 24 along the oil discharge hole 21 and is stored.

이에 따라서 오일의 낭비방지 및 바닥의 청결유지가 용이한 것이다. 요홈(22)부와 오일저장홀(가)부에 고여있는 오일에 의해 플런져(5)의 표면에 오일이 공급되어 부시(6)와 플런져(5)의 기밀이 유지되는 작용효과가 있으며 요홈(22)부와 오일저장홀(가)의 오일이 소모될 때까지 윤활유의 공급이 불필요하므로 종래의 오일 공급시 플런져(5)의 표면을 따라 흘러내며 낭비된 오일도 오일저장통(24)에 고이게 되어 재사용이 가능하므로 오일의 낭비를 방지할 수 있는 효과가 있고 종래 여분의 오일이 바닥으로 흘려내려 청결유지가 곤란하였으나 오일 저장통(24)이 있어 여분의 오일이 바닥으로 흘러내리지 않게 되어 바닥의 청결유지가 용이한 효과가 있는 유용한 고안이다.Accordingly, it is easy to prevent the waste of oil and to keep the floor clean. Oil is supplied to the surface of the plunger 5 by the oil accumulated in the recess 22 and the oil storage hole, thereby maintaining the airtightness of the bush 6 and the plunger 5. Since the oil supply is unnecessary until the oil in the groove 22 and the oil storage hole is consumed, the oil is flowed along the surface of the plunger 5 during the conventional oil supply and the waste oil 24 is also wasted. It can be reused because it can be used to prevent the waste of oil, and it is difficult to maintain the cleanliness because the extra oil was spilled to the floor, but there is an oil reservoir 24 so that the extra oil does not flow down to the floor. It is a useful design that is easy to maintain the cleanliness of.
