[0002] The leaf spring bracket is a connecting component used to connect the leaf spring to the frame. During the installation process, the leaf spring bracket is first fixedly connected to the frame by bolts, and then the leaf spring is fixed to the leaf spring bracket.

[0003] Since the frame of a semi-trailer is large and heavy, during the installation of the leaf spring bracket, the frame of the semi-trailer is generally used as the fixed end, and then the leaf spring bracket is moved to align and align the leaf spring bracket with the mounting holes on the semi-trailer frame, and then the leaf spring bracket is fixedly installed on the semi-trailer frame. During this process, two installers are generally required, one person aligns and fixes the leaf spring bracket and holds the leaf spring bracket, and the other person installs the bolts. Only by cooperating with each other can the installation be completed. The leaf spring bracket is also heavy, and the labor intensity of the personnel who hold and align at the same time is relatively high. Therefore, in order to reduce the labor intensity of the leaf spring bracket installers and improve the installation efficiency, a leaf spring bracket installation and fixing mechanism for a semi-trailer is needed to assist in the installation of the leaf spring bracket.

[0019] Example 1

[0020] In a typical implementation of the present invention, Figure 1-Figure 2As shown, a leaf spring bracket installation and fixing mechanism for a semi-trailer is proposed.

[0021] It includes: a moving device, a lifting cylinder 2 and a support plate 1. The lower part of the support plate 1 is connected to the moving device through the lifting cylinder 2. The lifting cylinder 2 drives the support plate 1 to move up and down on the moving device. Two limit blocks 5 are provided at one end of the support plate 1 away from the lifting cylinder 2. The limit blocks 5 support the leaf spring bracket 9. The distance between the two limit blocks 5 is the same as the distance between the mounting holes on the frame, which is convenient for aligning and installing the leaf spring bracket 9 after it is placed on the limit blocks 5. After the leaf spring bracket 9 is moved to the installation position of the frame by the moving device, it is directly aligned by lifting the lifting cylinder 2, without the need to manually lift the leaf spring bracket 9, thereby reducing the labor intensity of the installer.

[0022] like Figure 1 As shown, there are four lifting cylinders 2, which are distributed on the four corners of the support plate 1. The push rods of the lifting cylinders 2 are perpendicular to and fixedly connected to the support plate 1, and the cylinder bodies of the lifting cylinders 2 are perpendicular to and fixedly connected to the moving device, so that the lifting of the support plate 1 by the lifting cylinders 2 is more stable.

[0023] like Figure 2 As shown, one end of the limit block 5 is aligned with the edge of the support plate 1, so that when the leaf spring bracket 9 is installed, one end of the limit block 5 is in close contact with the frame, which facilitates the leveling and alignment of the leaf spring bracket 9.

[0024] like Figure 2 As shown, the two limit blocks 5 are axially symmetrical with respect to the center line of the support plate 1 , so that the two limit blocks 5 are located at the exact center of the support plate 1 , which facilitates the alignment between the leaf spring bracket 9 and the vehicle frame.

[0025] like Figure 2 As shown, the limiting block 5 is in the shape of an elongated strip, and the length of the limiting block 5 is smaller than the length of the supporting plate 1 .

[0026] like Figure 1 As shown, the mobile device includes: a base plate 3, a roller 7 is provided under the base plate 3 for easy movement, the side of the base plate 3 away from the roller 7 is fixedly connected to the cylinder body of the lifting cylinder 2, an operating box 4 is provided at one end of the base plate 3, and a push handle 6 is also provided on the side of the operating box 4 away from the base plate 3, so that the mobile device can be pushed conveniently by the push plate.

[0027] The operating box 4 is provided with an air pump and a power supply, the power supply supplies power to the air pump, and the air pump provides power to the lifting cylinder 2.

[0028] like Figure 2As shown, the operation box 4 and the bottom plate 3 are perpendicular to each other, and a lifting button 8 is also provided on the operation box 4, through which the lifting cylinder 2 is controlled to rise and fall.

[0029] When the mounting hole of the frame is at the height of the mounting hole, the lifting cylinder 2 is closed, and the mounting hole of the leaf spring bracket 9 is aligned with the mounting hole on the frame by pushing the moving device. In this way, the alignment and correction of the leaf spring bracket 9 are completed, and then the bolts are installed. Finally, the leaf spring bracket 9 can be fixed on the frame of the semi-trailer, which reduces the labor intensity of the installers in lifting the leaf spring bracket 9 for a long time. Moreover, since the frames of the semi-trailers are placed horizontally, after one leaf spring bracket 9 is installed, there is no need to adjust the lifting cylinder 2. It is only necessary to push the moving device to the position of the next mounting hole. This saves the time for correction and alignment in the vertical direction and improves the efficiency of the installation and fixation of the leaf spring bracket.

[0030] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
