The upper surface 5a or 5'a of the support 5 or 5' is brought into contact with b and suspended.

Therefore, when transporting a vehicle model with a different cross-sectional shape of the joint portion 3 or 3', the hanger receiving portion 4
It takes a lot of effort to replace the support part a. Furthermore, while the pressure receiving area of the support 5 or 5' that abuts the joint portion 3 or 3' is small,
Since the cab 1 is extremely heavy at several hundred kilograms, there is a problem in that the joint 3 or 3' may be deformed, such as denting due to its own weight.

The present invention was developed to solve the above problems, and it can be applied to vehicle models with different cross-sectional shapes of the upper joint of the door opener without replacing the supporter of the hanger receiving part, and it also aims to increase the pressure receiving area of the support. The purpose of the present invention is to provide a cab transport hanger.

(Means for Solving the Problems) In order to achieve the above object, according to the present invention, a support disposed in a hanger receiving part is brought into contact with the lower end surface of the upper joint part of the cab door opener, and the above-mentioned hanging is carried out. In the cab transport hanger for transferring cabs, first and second cabs are respectively capable of abutting on different positions of a common cross section of the joint lower end surface of the door opener.

a balancing mechanism that supports each of the supports in a floating manner and equally receives the load applied to each of these supports; The balance beam has a structure including cam means provided at both ends of the balance beam and capable of coming into contact with the lower surfaces of the first and second supports.

(Function) The first and second supports move relative to each other while being guided by the guide bar according to the cross-sectional shape of the joint at the top of the door opener, and come into contact with each other, and the balance mechanism moves these supports into contact with each other. The supports are supported at positions where they can be contacted, and the supports are balanced so that the loads applied to each support are equal. This eliminates the need to replace the hanger support even when different types of cabs are to be transported. Furthermore, since the two supports come into contact with the joint, the pressure receiving area increases and the load is distributed.

(Example) An example of the present invention will be described below in detail based on the accompanying drawings.

The support 12 is composed of two supports 20 and 21, and the base 22 of the support 20 has a cross section of approximately L.
The cross section of the base 23 of the support 21 is slightly rectangular, and each base 23 is slightly longer than the substrate 10. Each of these bases 22 and 2
As shown in FIG. 4, grooves 22a, ridges 22b, and ridges 23a, 23b are formed on the end surfaces of the base 22 and the grooves 23a and 23b, respectively, which are in sliding contact with each other. The protrusions 23a, the protrusions 22b of the base 22, and the grooves 23b of the base 23 engage with each other, so that the bases 22 and 23 can move up and down relative to each other without shifting in the longitudinal direction. One end of a stopper 24 is screwed and fixed to each end face of the base 23, and each other end 24a (only one shown) of each stopper 24 is connected to each end face 22c (only one shown) of the base 22.

As shown in the figure, a guide 33 is arranged and fixed opposite the end surfaces of the supports 20 and 21. This guide 33 is made of a rubber member, for example.

The action will be explained below.

If the cross-sectional shape of the upper joint 3 of the door opener 2 of the cab 1 (FIG. 7) is as shown in FIG. , and then raise the hanger 4 as shown by arrow B. Assume that the receiving part 4a rises as the hanger 4 rises, and the upper surface 30a of the pad 30 of one of the supports 20 comes into contact with the end surface 3b of the joint part 3 first. The support 20 is prevented from moving upward when the pad 30 comes into contact with the end surface 3b, and as a result, the bottom surface 22d of the support 20 presses the cam follower 15 on one side of each balance mechanism 11 as the receiving portion 4a rises. This causes the balance beam 14 to rotate clockwise, causing the cam follower 15 on the other side of each balance mechanism 11 to rotate.
pushes up the bottom surface 23d of the base 23 of the support 21. The support 21 rises until the upper surface 31a of the pad 31 comes into contact with the end surface 3a of the joint portion 3. Each pad 30 of these two supports 20, 21,
When the upper surfaces 30a, 30a of the joint part 31 come into contact with the opposing end surfaces 3b, 3a of the joint, the movement of each of these supports 20, 21 is stopped, and an equilibrium state is established.
As the hanger 4 rises, the receiving part 4a becomes two pads 3.
0,31 to push up the joint 3, and the cab 1
lift up.

Each balance mechanism 11 maintains each support 20, 21 in balance using a balance beam 14 and each cam follower 15, 15 at both ends of the balance beam 14, and supports the supports 20, 21 with equal loads applied thereto. . As a result, since the joint part 3 is supported by the two supports 20 and 21, the pressure receiving area increases and is evenly supported.
0 and 31 have elasticity and can be deformed according to the shapes of the end surfaces 3b and 3a, thereby preventing deformation such as denting of the joint portion 3.

Also, in the case of the cross-sectional shape of the joint 3' as shown in FIG. 6, each balance mechanism 11 operates in the same manner as in the case shown in FIG.
The upper surfaces 30a, 31a of the pads 30, 31 abut against the opposing end surfaces 3'b, 3'a of the joint 3. That is, the two supports 20 and 21 float according to the cross-sectional shape of the joint, and equally receive the load applied to the joint 3. Therefore, it is possible to support the joint portions 3 or 3' of two types of cabs having different cross-sectional shapes by the supports 20 and 21.

(Effects of the Invention) As explained above, according to the present invention, the cab transport hanger is configured to suspend the cab by bringing the support provided in the hanger receiver into contact with the lower end surface of the upper joint of the cab door opener and to transport the cab. , first and second supports that can respectively abut on different positions of a common cross section of the joint lower end surface of the door opener, and are provided between the first and second supports and the hanger receiver. , a guide bar that allows relative movement of the first and second supports with respect to the hanger receiver, a guide bar that is disposed between the hanger receiver and the first and second supports, and a guide bar that allows the first and second supports to move relative to the hanger receiver; a balancing mechanism that supports each of the supports in a floating manner and equally receives the load applied to each of these supports; Since the structure includes cam means that are provided at both ends of the balance beam and can come into contact with the lower surfaces of the first and second supports, the door opener can be attached to a cabin with a different cross-sectional shape of the lower end surface of the door opener joint without replacing the supports. It is possible to suspend the cab, improving work efficiency and saving labor, and the two supports reduce the vertical load of the cab by collaborating with the cab's own weight and the balance beam. By balancing the supports and supporting the joint, the pressure-receiving area can be increased, the load can be evenly received, and deformation of the joint can be prevented, which is an excellent effect.
