Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to improvement of a floor lift used for inspection and maintenance, alignment measurement, wheel / axle measurement, etc. of a four-wheel vehicle.

[0002]

[Prior art]

 Floor lifts used for inspection and maintenance of four-wheeled vehicles, alignment measurements, etc., connect a base plate fixed to the floor surface and a pair of left and right tables supporting front and rear wheels with an X-shaped link, The table can be raised / lowered in parallel with the floor surface by raising and lowering the X-shaped link by driving a hydraulic cylinder. Since there is a step between the table and the floor in the lowered state, the boarding of the table is made smooth so that the vehicle can get into (enter) the table and get out of the table (exit) smoothly. A board is attached to the side edge by a hinge structure. In addition, a stopper that functions as a wheel stopper is integrally connected to the end of the board on the table side, and the stopper is not aligned with the board so that it makes contact with the upper surface of the table, but at an angle. Connected.

[0003]

[Problems to be solved by the device]

 By the way, the floor surface on which this seed floor lift is installed is somewhat uneven and there are few flat areas, and the height from the floor surface to the table is different depending on the installation location due to the water gradient. Therefore, when the tip of the board is in contact with the floor surface when the table is in the lowered position, the board tilts upward toward the table, and the stopper connected to the board floats from the surface of the table. There may be a gap with the stopper. In this case, when the front and rear wheels step on the stoppers when the vehicle gets in and out, the board gets flapping, which causes the tip of the board to hit the floor and generate noise, or the floor and board. It causes problems such as damage to the. Of course, the above problems can be solved by changing the angle of the stoppers that are connected to the tip of the boarding board depending on the situation of each installation location. It is practically impossible to change to.

The present invention has been made in view of the problems of the above-described conventional technique. The purpose of the present invention is to set the upper surface of the table even if the installation location is not flat and the water gradient is different. (EN) Provided is a floor type lift in which a clearance does not occur between a stopper and a board is not fluttered when a vehicle gets in or out.

[0005]

[Means for Solving the Problems]

 The technical means taken by the present invention to achieve the above-mentioned object is that the boarding plates attached to the end portions of the pair of left and right tables for supporting the front and rear wheels can be raised and lowered at the side edges of the table. And a stopper member pivotally supported toward the table side on a shaft supporting portion of the boarding side member, and the stopper member is directed downward in the boarding side member as the table rises. It is characterized in that it is rotated in association with the rotation of and is raised on the table.

The upright movement of the stopper member associated with the rotation of the boarding-side member is performed by fitting the end portion of the stopper member on the side of the shaft supporting portion into the lower side of the end of the shaft supporting portion of the boarding side member. Characterize. In this case, a certain amount of play is provided in the overlapping portion of the board-side member and the stopper member.

The lifting mechanism for the floor type lift, which is the subject of the present invention, may be either a combination of an X-shaped link and a hydraulic cylinder or a plunger lift, and the left and right tables may be used for freewheeling. It may be a lift equipped with an auxiliary table.

According to the above means, the tip of the boarding-side member is tilted while being in contact with the noodles at the lowered position of the table, but since the stopper member is separated from the boarding-side member, the boarding-side member It contacts the table top regardless of the inclination, and there is no gap between the table top and the stopper member. Therefore, when the vehicle is loaded onto the table or when the vehicle is exited from the table, the entry side member does not flutter. Further, after the vehicle has loaded on the left and right tables, the elevating mechanism is operated to raise the table, and as the table is raised, the entry side member pivots downward about the pivotal support. With this rotation, the overlapping portion of the stopper member is pressed downward, and the release end side of the stopper member is rotated so as to stand on the table with the rotation of the boarding side member, and the wheel stopper of the vehicle is stopped. Becomes Of course, when the table is lowered, the boarding side member and the stopper member automatically return to the initial state.

[Embodiment of device]

 An example of an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an outline of an on-floor lift, in which 1 is a pair of left and right tables on which front and rear wheels are mounted, and 2 is a front. An X-shaped link 3 that connects the table 1 and a substrate (not shown) fixed to the floor is a hydraulic cylinder that raises and lowers the X-shaped link 2 and moves up and down by the X-shaped link 2 and the hydraulic cylinder 3. A mechanism is configured, and a boarding plate 4 is attached to one side (boarding side) of the pair of left and right tables 1.

The board 4 is a board-side member 5 that is rotatably supported by the end of the table 1, and a shaft-supporting part of the board-side member 5 that is rotatable toward the table 1. The stopper member 6 is axially supported, and the end portion of the stopper member 6 on the shaft support portion side is fitted to the lower side of the boarding side member 5. Hereinafter, the boarding-side member 5 and the stopper member 6 will be described in more detail.

The boarding-side member 5 is formed in a flat rectangular shape using a metal flat plate, and one end (ground side) of the boarding-side member 5 smoothly slides on the surface of the floor when the table is lifted / lowered. A roller 7 is attached so that it can rotate freely, a rectangular reinforcing frame 8 is fixed to the back side of the metal flat plate by welding, and the reinforcing frame is attached to the other side (mounting side to the table). A mounting plate 10 having pins 9 fixed to the front and rear parts of 8 is fixed to the back surface of the metal flat plate by welding with a gap slightly wider than the plate thickness of a stopper member 6 described later. The pins 9 should be fixed to the mounting plate 10 in the same direction so that the pins 9 are aligned with the bearings 11 fixed to the side edges of the table 1 and moved in the front-back direction. It is configured to connect with.

The stopper member 6 is formed in a rectangular shape narrower than the width of the boarding-side member 5 by using a metal flat plate like the boarding-side member 5 described above, and is mounted on one end portion on the back side of the plate. Bearings 12 are suspended and fixed at intervals so that they can be fitted to the front and rear pins 9 fixed to the insertion side member 5. Therefore, by arranging the bearing 12 of the stopper member 6 in contact with one side of the bearing 11 of the table 1 and aligning the pin 9 of the board-side member 5 with this, and inserting it from the side, At the same time that the board-side member 5 is connected, the attachment of the stopper member 6 is completed. The end of the stopper member 6 on the pivotal support side is fitted between the back side of the boarding-side member 5 and the mounting plate 10, whereby the boarder-side member 5 is rotated downward so that the stopper is formed. Similarly, the end portion of the member 6 on the shaft support side is similarly pushed downward, and the release end side of the stopper member 6 is rotated from the horizontal state to the standing state.

[Effect of device]

 The floor lift according to the first and second aspects of the present invention has the boarding board on the boarding side even if the floor on which the lift is installed is not flat and has irregularities or water gradients are different. Since the member and the stopper member are separated, the stopper member is not affected even if the inclination angle of the boarding side member changes, and the stopper member maintains the state of being in horizontal contact with the upper surface of the table. To do. Therefore, the boarding side members are not fluttered when boarding the table or when exiting the table, which results in the noise generated by the conventional device, the problem of damaging the floor surface, and the damage of the boarding board. Such problems can be solved. Also, even if the stopper member is separated from the boarding side member, since one end portion is overlapped, it is erected due to the downward rotation of the boarding side member as the table rises, and like the conventional device. Can act as a wheel stop.
