Abstract

PURPOSE: A step-elevating transmission device is provided to move only with a load panel upon moving on a flat ground, to easily perform a step-elevating work by combining a step-elevating driving unit with a load panel upon needing to elevate a step and to remove a danger caused by the overturn of the device. CONSTITUTION: In transmitting a freight on a plain ground, fixing pieces(13,13a) on a front and a rear side of a lower load panel(7) are separated from a step-elevating driving unit by separating a bolt(16). The device is moved by tightly holding handles(3,3a) using fixing sticks(8,8a) and wheels(T, Ta). When a cylinder rod(12) is drawn out by combining the lower load panel with the step-elevating driving unit by the bolt(16), a horizontal supporting stick(11a) connected with the cylinder rod(12) is pushed up, and posts(2,2a) connected with the horizontal supporting stick is slanted toward a front side. Then the freight load panel(4) connected with a lower end of the posts is slanted. Herein, when a chain begins to travel on the step, it elevates or descends along with a step corner in a state that the freight load panel keeps horizontal. Thereby, the weight center of the loaded freight is always kept in the center of the transmission device.

화물의 계단 승강 이송장치Stair lifting conveyor of cargo

본 발명은 무거운 화물을 적재한 상태에서 평지는 물론 계단을 용이하게 승강할 수 있는 동력 승강장치에 대한 분야로서 종래에도 평지 및 경사면 또는 건물계단을 거슬러 상승하는 운반장치들이 다수 제시되었으나, 대부분의 운반장치들은 스크류 등의 수단을 구비하여 화물적재패널(panel)을 상승·하강하도록 하여 화물의 적재가 용이하도록 하거나 운반장치의 주행 안전성을 고려한 장치의 부가, 또는 경사면 또는 계단을 상승주행하다 임의로 후진되는 것을 방지하거나 무한궤도를 장치하여 계단을 승강하도록 함에 있어 무한궤도에 임의의 형상으로 돌턱을 돌설시켜 계단모서리에 걸리게 하므로서 미끄러짐을 방지하도록 한 것에 대한 것 등등이 제안되어 있다.The present invention is a field for a power lifting device that can easily lift the stairs as well as flat ground in the state of loading heavy cargo, but a number of transport devices have been presented in the past, ascending the flat and slope or building stairs, most of the transport The devices are provided with means such as screws to raise and lower the cargo loading panel to facilitate the loading of cargo or to add the device considering the driving safety of the transportation device, or to drive up the slope or the stairs. It is proposed to prevent slipping by placing a stepping stone in an arbitrary shape on the track, to prevent the slip or to climb the stairs by installing the track.

상기와 같이 화물을 적재하여 계단이나 경사면을 승강하도록 하는 다수의 화물승강이송장치는 화물을 적재하는 화물적재패널을 수평으로 고정되게 한 것들로서 이러한 이송장치의 패널은 경사면이나 계단 등을 승강할 때는 패널 또한 경사면이나 계단 등의 기울기대로 기울어지므로서 적재된 화물의 무게가 구동수단의 중심을 벋어나게 되어 후방으로 전복되려는 백터방향으로 무게중심이 이동되므로 상승운반 작업시 위험하고 전복을 방지하기 위한 별도의 버팀바퀴장치가 부가되어 장치가 복잡하고 차체중량이 늘어나는 등의 문제점이 있어 왔다. 또한, 상기 종래의 장치들은 모두 구동수단 또는 이동수단과 화물적재패널이 일체로 구성되어 있어 평지이동시에도 계단 승강 때 필요한 장치들이 그대로 부착되어 있어 평지사용이 불편하는 등의 문제점이 상존하였다.As described above, a plurality of lift elevators which load cargo and lift stairs or slopes are horizontally fixed cargo loading panels that load cargo, and the panel of the transfer apparatus is a panel when climbing a slope or stairs. In addition, as the weight of the loaded cargo is out of the center of the driving means as it is inclined by the slope of the slope or the stairs, the center of gravity is moved in the direction of the vector to be rolled over, so it is dangerous during the lift operation, There has been a problem in that the support wheel device is added and the device is complicated and the body weight is increased. In addition, the conventional devices are all composed of a driving means or a moving means and a cargo loading panel integrally attached to the devices necessary for the ascending and falling of the stairs even during the movement of the flat, there is a problem such as uncomfortable use of flat.

Shaft 9 is laid between the fixing rods 8 and 8a and freely rotated at both ends of this shaft. A qui (T) (Ta) is mounted and the lower side is fixed to the shaft (9) on both sides of this shaft (9), and the upper end of the upper stem (2) (2a) hangs or spaces on the hanging frame (10). The two horizontal support sections 11 and 11a are fixed to the left and right posts 2 and 2a between the left and right posts 2 and 2a, and the cylinder is disposed between the lower horizontal support section 11a and the shaft 9. (12) is interposed, the fixing piece (13) (13a) to the center of the front and rear of the loading panel base plate 7, and the bottom of the loading final plate (7) is in close contact with the bottom of the loading panel base plate (7) and the space portion ( 14 is provided with a drive unit 15 is formed, the fixing piece 13 (13a) and the drive unit 15 of the mounting panel bottom plate 7 is detachably coupled by a fastening means such as a bolt 16, and the left and right sides of the drive unit The caterpillar chain 17 and 17a having a constant width and length are positioned and the main and driven sprockets 18 and 18a are interposed before and after the inside of the chain. The stepped elevator transport apparatus 1 for cargoes according to the present invention is constructed by carrying out a squeezing of the geared motor 19 shaft 20 with a fixed reduction ratio fixed to the unit. In the figure, reference numeral 21 denotes a control rod mounted with a switch for controlling on and off of the motor and a rod pull-out of the cylinder 12, and 22 denotes a battery for supplying power to drive the motor 19. . And (23) (23a) is an auxiliary handle that the worker grips when the stairs are elevated.

상기와 같이 구성된 본 발명장치는 평지에서의 화물이송때에는 적재패널저판(7) 전후측의 고정편(13)(13a)과 계단승강구동부(D)를 볼트(16)를 해리하므로서 분리하여 적재패널저판(7) 양측선단에 고착된 고정간(8)(8a) 및 축(9) 좌우선단에 취부된 바퀴(T)(Ta)를 사용하여 사람이 인력으로 손잡이(3)(3a)를 파지하여 이동하고 경사면 또는 계단을 승강할 때에는 적재패널저판(7)과 계단승강구동부(D)를 볼트 (16)로 결합하여 실린더(12)의 로드를 인출시키면 실린더(12) 로드와 연결된 가로지지간(11a)을 밀어올리고 이 가로지지간(11a)과 고착연결된 포스트(2)(2a)를 전방으로 기울어지게 하며 이 포스트(2)(2a) 하단과 고착연결된 화물적재패널(4)을 기울어지게 하는 바 이는 계단의 경사면을 체인(17) 및 구동부(15)로 구성된 주행장치가 힌지(6)을 중심으로 하여 계단의 하측으로 기울어짐을 의미하며 이때 계단을 체인(17)이 주행하기 시작하면 주행장치가 기울어짐에 따라 도면 도 3 과 같이 화물적재패널(4)은 수평을 유지한 상태에서 기울어진 주행장치의 체인(17)이 계단 모서리를 타고 상승 또는 하강하게 되므로 적재된 화물의 무게중심은 항상 이송장치(1) 중앙에 위치된 상태로 이송되게 된다.The device of the present invention configured as described above separates the fixed pieces 13 and 13a and the step-up and down driving part D from the front and rear sides of the loading panel bottom plate 7 by dissociating the bolts 16 when the cargo is transported on a flat surface. A person grasps the handle (3) (3a) by manpower by using the fixed rod (8) (8a) fixed to both ends of the bottom plate (7) and the wheel (T) (Ta) mounted at the left and right ends of the shaft (9). In order to move up and down an inclined surface or stairs, the loading panel base plate 7 and the step elevating drive unit D are coupled with bolts 16, and the rod of the cylinder 12 is pulled out. 11a) to push up and incline the post (2) (2a) fixedly connected to this transverse support (11a) and to tilt the cargo loading panel (4) securely connected to the bottom of this post (2) (2a). This is because the traveling device composed of the chain 17 and the drive unit 15 has the inclined surface of the staircase as the lower side of the staircase. In this case, when the chain 17 starts to run down the stairs, as the traveling device is inclined, the cargo loading panel 4 is inclined to maintain the horizontal chain 17 as shown in FIG. 3. ) Will rise or descend on the edge of the staircase, so that the center of gravity of the loaded cargo is always transported in the state positioned in the center of the conveying apparatus (1).

상기와 같이 평지에서는 이송장치를 볼트(16)를 해리하므로서 분리하여 가볍게 화물을 적재하여 인력만으로 이동하고 경사면이나 계단을 승강할 때에는 이송장치를 간단히 화물적재패널(4) 저면과 볼트로 결합하여 동력으로 화물적재패널(4)을 수평을 유지한 상태로 간단하고 안전하게 이송할 수 있는 대단히 유용한 발명이다.As described above, the conveying device is separated by dissociating the bolt 16 and lightly loaded to move the cargo only by manpower. This is a very useful invention that can easily and safely transport the cargo loading panel 4 in a horizontal state.
