Description

[Detailed Description of the Invention] Technical Field The present invention relates to a vehicle lifting device, and in particular, when loading a trunk onto a freight car, it can be done quickly and safely without damaging bumpers, front panels, etc. The present invention relates to a vehicle lifting device capable of lifting the truck.

PRIOR ART Conventionally, when loading a trunk onto a freight car, for example, the front part of the truck is lifted by an A-type crane.
The front axle of the next truck was placed on top of the chassis of another truck, which had already been loaded, and the trucks were loaded one after another by tilting them one on top of the other. In this case, flexible members such as ropes and belts hanging from the hooks of the crane may be hung directly on the front bumper, or a chain may be hung at an appropriate location at the bottom of the chassis to connect the chain and the flexible member. The only way to do this is to use a crane to lift the front of the truck, and even if the bumper has sufficient lifting strength, this method will damage the paint on the bumper and damage the paint on the front panel. However, if the strength of the bumper is insufficient, the bumper will be greatly deformed, which will reduce the commercial value of the new car. In addition, the loading platform of a freight car is narrow (and the footing is poor), so hooking the chain to the bottom of the chassis and removing it when loading is completed is not easy, is quite dangerous, and takes a long time. Ta.

Additionally, when a vehicle becomes stuck on the road due to engine trouble, etc., the front part of the vehicle is lifted up by the tow truck's crane and towed, but this also causes damage to the front and bumper of the vehicle. There were drawbacks.

Purpose The present invention has been made to eliminate the drawbacks of the prior art described above, and its purpose is to support the lower surface of the chassis frame at the front of a vehicle and the front end of the front axle leaf spring. Moreover, by providing a pair of lifting members whose front ends protrude ahead of the bumper of the vehicle, and lifting the front ends of the lifting members with a crane, ropes, belts, etc. hanging from the crane can be lifted. Eliminates the need to hang flexible members on the bumper, prevents deformation of the bumper, damage to the paint, and damage to the paint on the front panel of the vehicle. Another object of the invention is to engage one end of the lifting member with the front end of a front axle leaf spring toward the side of the vehicle; By providing a leaf spring support part to support the lifting member, the lifting member can be attached to and detached from the vehicle with one touch.This also makes the work much easier and easier than conventional chain hooks. The purpose is to significantly shorten the time and improve safety.Furthermore, another purpose is to provide a connecting device in which the central portions of the main bodies of a pair of lifting members are rotatably connected to each other. By lifting the suspension members using a flexible member so that the front ends of the lifting members approach each other, the leaf spring support parts expand toward the sides of the vehicle, so that the leaf spring support parts bite into the front end parts of the leaf spring by themselves. This is to ensure that the lifting member never comes off the vehicle while the vehicle is being lifted, and to provide extremely high safety while lifting the vehicle.Another purpose is to ensure that the entire lifting member By covering the lifting member with a soft material, the paintwork will not be damaged even if the lifting member hits any part of the vehicle during installation/removal work.Furthermore, another purpose is to cover one end of the connecting member with a soft material. To facilitate attachment and detachment of a lifting member to a vehicle by pivotally attaching the lifting member to a member and configuring the other end to be detachably attached to the other lifting member by means of a bin part, and to enable the lifting members to be easily carried one by one. .

The other end 20b is rotatably connected to a bracket 21 fixed to the rear of the freight car 16 via a bolt 22.

Function The present invention is constructed as described above, and its function will be explained below. First, with reference to FIGS. 1 to 10, a trunk 5 is lifted using a vehicle lifting device 1 according to the present invention.
A case will be described in which a case where the vehicle is loaded onto the freight car 15 will be explained. As shown in FIG. 1, in order to load the truck 5 onto the freight car 15, a crane (A-type crane) having a pair of legs 1'la and a pair of wheels 11b is used, and the crane is placed at the front and rear of the freight car 15. A plurality of trunks 5 are stacked diagonally one after another from the front as shown in FIGS. 1 and 2. A hoist 2 is installed on the upper part 11c of the crane 11.
3 is suspended, and a hook 25 is suspended from the lower part of the hoist by a wire 24, and a flexible member 1 is attached to the hook.
The upper part of 2 is hooked. The lower ends of the flexible members connect to the hook portions 2f of the lifting members 2 and 3 of the vehicle lifting device 1 according to the present invention via joints 26 and 28.

Each can be hooked to 3F. In this case, since the lifting members 2 and 3 are each suspended by the lower end of the flexible member 12, the worker 29 must use his/her physical strength to absorb the weight of the lifting members 2 and 3 when attaching them to the truck 5. There is no need to hold them by any means, and it is sufficient to simply hold them lightly and mount them under the chassis frame 6 in the following manner.

First, to explain the case where the lifting member 2 is attached to the truck 5, the leaf spring support part 2e formed at the rear end part 2c of the main body 2a is connected to the front end part 1 of the front axle leaf spring lO.
0a from the center side of the track 5 toward the inner side surface 10b, and at the same time bring the guide member 3 into contact with the outer side surface 6b of the chassis frame, and then insert the guide member 3 into the chassis frame support portion 2d.
is located directly below the lower surface 6a of the chassis frame 6.

This completes the installation of the lifting member 2. Next, the lifting member 3 is attached to the lower part of the chassis frame 6, and the mounting method is exactly the same as described above. The guide member 3g is inserted toward the inner side surface 10b of the spring 10, and then the guide member 3g is brought into contact with the outer side surface 6b of the chassis frame 6, and the chassis frame support portion 3d is positioned directly below the lower surface 6a of the chassis frame 6. Then, the connecting tool 4, which had been held under pressure by the holding part 2j of the lifting member 2, is rotated as shown by the arrow A in FIG.
It is removed from the holder, and the pin portion 4C is inserted into the bracket 31 of the lifting member 3 from above to connect it. In this way, the lifting member 2°3 is attached to the chassis frame 6 of the truck 5.
The mounting condition shown in FIG. 4 is as shown in FIG. Then, the worker 29 uses the hoist 2 via the rope 30.
3, the hoist 23 raises the hook 25 via the wire 24, so that the flexible member 12 is pulled upward. In this case, the upper end of the flexible member 12 is combined into one, and the lower end is the lifting member 2,
When the hooks 25 are raised, the flexible member 12 is pulled up as shown by arrow B in FIG. A component force F directed toward the center of the trunk 5 is generated in the portions 2b and 3b. Due to this component force F, the lifting members 2.3 are subjected to moments in opposite directions as shown by arrows C and D in FIG. 4, respectively.

As a result, the lifting member 2.3 has its front end 2b.

3b try to approach each other as shown by arrows C and D,
Further, the rear end portions 2C and 3C tend to expand outward as shown by arrows G and H, respectively. For this reason, the lifting member 2
The leaf spring support part 2e of the truck 5 is pressed against the inner side surface 10b of the leaf spring 10 on the left side in the direction of travel, and the leaf spring support part 3e of the lifting member 3 is pressed against the leaf spring 1o on the right side in the direction of travel.
It will be pressed against the inner side surface 10b of. Therefore, the heavier the truck 5, the stronger the force applied to the lifting member 2.
．． The leaf spring support parts 2e and 3e of No. 3 strongly support the leaf spring 10, respectively.
The chassis frame support portion 2d acts as if it bites into the chassis frame support portion 2d.

3d is in close contact with the lower surface 6a of the chassis frame 6,
It receives the weight of the front part 5a of the truck 5, and also the guide part 2g,
3g is pressed against the outer side surface 6b of the chassis frame by the moments shown by arrows C and D, so there is no possibility of displacement, and in this way, the hook 25 is raised by the hoist 23, and the flexible When the member 12 lifts the lifting member 2.3 upwards, the front part 5a of the truck 5 will be lifted upwards as shown in FIG. In this case, the front end 2 of each lifting member 2゜3
b and 3b protrude considerably forward than the front part 5a of the truck 5 and the bumper 8, and the visibility member 12
, joints 26, 28, etc., do not come into contact with any part of the front part 5a of the truck 5, so there is no possibility that any part of the truck will be damaged by these, and the truck can be lifted safely. When the lifting of one truck 5 is completed, the crane 1
1 moves forward with its wheels 11b, and the truck 5
is advanced by the rear wheels 31 in the same direction over the freight car 15, and is loaded onto the truck 5, which has already been loaded, as shown in FIG. 2, and the loading operation is completed.

Next, the removal work of the lifting member 2.3 when loading is completed will be explained. First, the worker 29 operates the rope 30 to operate the hoist 23 and the hook 2.
is lowered to loosen the flexible member 12. As a result, the moments indicated by arrows C and D in FIG. 4 are eliminated, and each lifting member 2.3 can be freely removed.

Therefore, first remove the bottle part 4C of the connecting tool 4 from the bracket 1-3i of the lifting member 3, and then attach it to the holder 2 of the lifting member 2.
It is held under pressure by j. Next, the leaf spring support part 3e of the lifting member 3 is removed from the leaf spring 10, suspended from the flexible member 12, and can be easily removed from the track 5. Next, when the leaf spring support part 2e of the lifting member 2 is removed from the leaf spring 10 in the same manner, the lifting member is also suspended from the flexible member 12 and can be easily removed from the track 5. . Then, each lifting member 2.3 is further lifted upward by the hoist 23, the crane 11 is moved rearward, and the next trunk 5 is similarly lifted and loaded.

As described above, several trucks 5 can be easily loaded onto one freight car 15.

In the above-mentioned lifting work, since the entire outer surfaces of the lifting members 2, 3 and the connecting tool 4 according to the present invention are covered with a soft material such as soft synthetic resin or rubber, in the event that any part of the truck 5 should Since the flexible member 12 and the like do not come into contact with the front part 5a of the trunk 5 even in the lifted state, the truck will not be damaged during any work. . Furthermore, since the lifting members 2 and 3 can be attached and detached with a single touch, the working time is significantly reduced compared to the conventional chain hanging operation, and the safety is also significantly improved.

Next, to explain the operation of the second embodiment shown in FIG. 11, the lifting members 2 and 3 are respectively attached to a broken vehicle (not shown) in the same manner as in the first embodiment, and these are connected to the connecting tool. The hook portion 2f is rotatably connected to the hook portion 2f via a flexible member (not shown) by a crane of an evacuation truck (not shown), for example.

When 3F is lifted, the front part of the vehicle is lifted,
Further, since the distance between the rear part of the tow truck and the front part of the broken down vehicle is kept constant by the connecting rod 20, the tow truck can travel safely. In this way, by using the lifting member 2.3 of the present invention, a tow truck can tow a vehicle that has broken down due to engine trouble or the like in an extremely safe, reliable and easy operation, which is also useful in improving road safety. The vehicle lifting device 1 according to the present invention can be used extremely effectively to tow a broken down vehicle without damaging it.

In the above embodiment, the vehicle is described as a truck 5, but this is not limited to a truck.
If the vehicle has a chassis frame and a front axle leaf spring, the vehicle lifting device 1 according to the present invention can be used as a pass,
Needless to say, it can be used to lift all types of vehicles, including passenger cars.

Effects Since the present invention is constructed and operates as described above, it is possible to support the lower surface of the chassis frame at the front of the vehicle and the front end of the front axle leaf spring, and furthermore, the front end of the main body can be attached to the vehicle. Since a pair of lifting members are provided that protrude ahead of the bumper, it is necessary to lift the front ends of the lifting members with a crane to hang flexible members such as ropes and belts hanging from the crane onto the bumper. This has the effect of preventing deformation of the bumper, damage to the paint, and damage to the paint on the front panel of the vehicle, making it easier to lift, load and unload onto freight cars without damaging any part of the vehicle. This provides the excellent effect of being able to be moved by other vehicles on the road. In addition, a leaf spring support part is provided at one end of the lifting member that engages with the front end of the front axle leaf spring toward the side of the vehicle and supports the front end, so that the lifting member can be attached to and removed from the vehicle with a single touch. As a result, compared to conventional chain hooks, the work can be made much easier, and the work time can be significantly shortened and safety can be improved. Furthermore, since a connecting device is provided in which the central portions of the main bodies of the pair of lifting members are rotatably connected to each other, by lifting the lifting members with the flexible member so that the front ends of the lifting members approach each other. , the leaf spring support portions each expand toward the side of the vehicle, and the leaf spring support portions have the effect of being able to bite into the end portions of the leaf spring by themselves.
Furthermore, as a result, the lifting member can be absolutely prevented from coming off the vehicle while the vehicle is being lifted, resulting in an effect that the safety during lifting of the vehicle can be made extremely high. In addition, since the entire lifting member is covered with soft material,
Even if the lifting member hits various parts of the vehicle during attachment/detachment work, there is an effect that the paint will not be damaged. Furthermore, the coupling device has one end pivotally connected to one of the lifting members and the other end configured to be detachably attached to the other lifting member by means of a pin, so that the lifting member can be easily attached and detached from the vehicle. This has the effect of allowing the lifting members to be easily carried one by one.
