Description

지게차의 틸트실린더 설치구조{Structure of mounting tilt cylinder in a fork-lift truck}Structure of mounting tilt cylinder in a fork-lift truck

본 고안은 지게차에서 하부에 포크를 갖는 마스트를 틸팅시키는 실린더에 관한 것으로, 특히 그 설치구조로써 지게차의 전경시 틸팅에 있어 실린더를 효율적으로 사용할 수 있게 한 지게차의 틸트실린더 설치구조에 관한 것이다.The present invention relates to a cylinder for tilting a mast having a fork in a lower part of a forklift, and more particularly, to a tilt cylinder installation structure of a forklift that enables the cylinder to be efficiently used in the foreground tilting of the forklift.

일반적으로 지게차의 포크에 짐을 전경 혹은 후경시킴에 있어, 전경시는 짐의 자중에 의해 전경되려는 힘이 작용하므로 틸트실린더에서 큰 힘을 낼 필요가 없으나, 후경시는 짐을 들어올리는 방향으로 작동되어야 하므로 틸트실린더는 큰 힘을 내어야 한다.In general, in the foreground or rear view of the load on the fork of the forklift truck, the foreground force is applied to the foreground by the weight of the load, so it is not necessary to apply a large force in the tilt cylinder, but the rear view should be operated in the direction of lifting the load. The tilt cylinder must exert great force.

그런데 이러한 종래의 틸트실린더 설치구조를 보면, 도 1에서와 같이 실린더 로드(R)가 너클로써 마스트(M)에 힌지결합되고 실린더(C)는 차체(B)에 역시 너클로써 힌지결합된다.However, in the conventional tilt cylinder mounting structure, as shown in FIG. 1, the cylinder rod R is hinged to the mast M as a knuckle, and the cylinder C is also hinged to the vehicle body B as a knuckle.

이러한 종래의 틸트실린더(C)의 작동관계를 보면, 작동유가 받는 압력면적이 도 1의 a방향으로 틸팅시 b방향으로 틸팅시보다 상대적으로 매우 적다. 이는 로드 (R)가 결합되는 단면적이 피스톤의 압력면적에서 제외되기 때문이다. 또한 비교적 큰 하중을 받는 틸팅작업으로써 로드(R)의 단면적도 다른 실린더에서와는 달리 상대적으로 크게 설계되므로써 크게 하중을 받는 도 1의 a방향, 즉 당김 틸팅시 작동유의 압력면적이 작아 틸트실린더의 크기에 비해 효율이 떨어지는 문제점이 있다. (f = Pa)Looking at the operation relationship of the conventional tilt cylinder (C), the pressure area received by the hydraulic oil is relatively less than when tilting in the b direction when tilting in the a direction of FIG. This is because the cross sectional area in which the rod R is coupled is excluded from the pressure area of the piston. In addition, since the cross-sectional area of the rod (R) is designed to be relatively large unlike other cylinders due to a tilting operation that is subjected to a relatively large load, the pressure area of the hydraulic oil in the a direction of FIG. There is a problem that the efficiency is lower. (f = Pa)

따라서, 본 고안은 이상과 같은 문제점을 해결하기 위해 창안된 것으로, 본 고안의 목적은 지게차의 잡아당김 틸딩시 동일한 작동 압의 기준에서 상대적으로 큰 면적에 유압이 작용되게 하여 틸트실린더의 효율성을 높이는데 그 목적이 있다.Therefore, the present invention was devised to solve the above problems, and an object of the present invention is to increase the efficiency of the tilt cylinder by allowing the hydraulic pressure to be applied to a relatively large area in the same operating pressure criteria when pulling and pulling the forklift. Its purpose is to.

상기 목적을 달성하기 위해 본 고안은 마스트에 힌지결합되는 연동로드와 그 하부에는 차체에 고정되는 틸트실린더를 구비하되, 상기 연동로드와 틸트실린더의 실린더로드 사이에는 역시 차체에 그 중앙이 힌지결합되는 링크의 상하단이 힌지결합된 것을 특징으로 한다.In order to achieve the above object, the present invention is provided with a tilt cylinder fixed to the vehicle body at a lower portion of the linkage rod hinged to the mast, and the cylinder rod of the linkage rod and the tilt cylinder is also hinged to the center of the vehicle body It is characterized in that the upper and lower ends of the link is hinged.

10 : 연동로드 20 : 링크10: linkage load 20: link

이하에서 본 고안을 바람직한 실시예를 첨부된 도면에 의해 보다 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the preferred embodiments as follows.

본 고안의 설명중 종래와 동일 또는 동등한 부분은 같은 부호로 표기하여 설명하기로 한다.In the description of the present invention, the same or equivalent parts as in the prior art will be described with the same reference numerals.

지게차에 틸트실린더를 설치함에 있어서, 마스트(M)에 힌지결합된 연동로드 (10)와 차체 하부에 고정된 틸트실린더(C)의 실린더 로드(R) 사이에는 차체(B)에 힌지결합되는 링크(20)의 상하단이 각각 힌지결합된 구성으로 이루어진다.In installing the tilt cylinder in the forklift, a link hinged to the vehicle body B between the linkage rod 10 hinged to the mast M and the cylinder rod R of the tilt cylinder C fixed to the lower part of the vehicle body. The upper and lower ends of 20 are each hinged configuration.

이상과 같이 구성된 본 고안의 동작을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

지게차에서 당김 틸팅작업시 큰 부하가 걸린다. 따라서 틸트실린더(C)에서 작동유가 종래와 같이 로드(R)측에 걸리지 않고 반대측 실린더(C)측에서 작용됨에 따라서 실린더로드(R)가 돌출된다.(F = PA 로써 면적(A)이 클수록 큰 힘을 발휘함)Pulling and tilting of forklift takes heavy load. Therefore, the cylinder rod R protrudes as the working oil is not applied to the rod R side in the tilt cylinder C and acts on the opposite cylinder C side as in the prior art. (The larger the area A as F = PA, the larger the area A is). Great power)

따라서, 링크(20)가 힌지점을 중심으로 도면상 시계방향으로 선회되고 이 선회로써 링크(20)의 상단이 연동로드(10)를 당김하여서 마스트(M)를 후경시키게 된다.Therefore, the link 20 is pivoted in the clockwise direction about the hinge point, and by this turning, the upper end of the link 20 pulls the interlocking rod 10 so that the mast M is rearviewed.

즉, 후경을 위해 큰 힘이 필요할 때 실린더(C)의 로드(R)를 피한 실린더 측에서 작동유를 가압하는 루트로 동일 제원의 틸트실린더에 있어서, 효율성을 제고할 수가 있는 것이다.That is, it is possible to improve the efficiency in the tilt cylinder of the same specification as a route for pressurizing the hydraulic oil on the cylinder side avoiding the rod R of the cylinder C when a large force is required for the rearview mirror.

이상과 같이 구성되고 작용되는 본 고안은 링크구조에 의한 작동유 방향의 변경만으로 지게차의 틸팅시 큰 힘을 받아야할 때 틸트실린더가 상대적으로 큰 힘을 발휘할 수 있도록 함으로써 동일 제원의 틸트실린더로 큰 효율성을 제고할 수 있으며, 또는 틸트실린더의 용량을 작게 할 수 있는 유용한 고안이다.The present invention constructed and operated as described above allows the tilt cylinder to exert a relatively large force when the forklift is subjected to a large force only by changing the direction of the hydraulic fluid by the link structure, thereby achieving great efficiency with the tilt cylinder of the same specification. It is a useful design that can increase the capacity of the cylinder or increase the capacity of the tilt cylinder.
