The mounting frame, as the reference limiting member and the mounting carrier for the mounting adjustment member, can straddle above the running surface of the vehicle when in use. In the accompanying drawings, the mounting frame used is a beam made of square steel. In fact, the mounting frame can also adopt other structural forms, for example, a frame structure assembled by a plurality of rods can be adopted, or a plate can be simply adopted.

The reference limiter includes two reference limiters, which are symmetrically arranged on the mounting frame, and are symmetrically arranged on both ends of the beam in the drawings. The two reference limiters have the same structure and are arranged in an L shape, including a horizontal and vertical section, and the horizontal and straight sections are connected with the mounting frame by fasteners. surface, while the vertical section is located inside the vehicle's running surface.

The bracket includes a vertical adjustment screw and a support plate; the installation and locking assembly includes a backing plate and a locking nut; the backing plate is placed on the upper surface of the beam, and the backing plate and the beam are correspondingly provided with a through waist The upper end of the vertical adjustment screw passes through the waist-shaped hole on the beam and the waist-shaped hole on the backing plate in turn, and then is locked by the locking nut, and the vertical adjustment screw The lower end of the L-shaped supporting plate is equipped with a supporting plate, and the supporting plate is arranged in an L shape. The vertical section of the L-shaped supporting plate is fixed with the lower end of the vertical adjustment screw by welding and fixing. bottom of the rail. It can be seen from this that the present invention adjusts the horizontal distance between the vertical adjustment screw and the guide rail to be installed by moving the vertical adjustment screw laterally (the left and right directions in the figure) in the waist-shaped hole, so that the vertical adjustment screw is installed below the vertical adjustment screw. The vertical section of the supporting plate can be closely attached to the side of the guide rail to be installed. In addition, the present invention also adjusts the vertical adjustment screw vertically (up and down in the figure), so that the vertical adjustment screw is installed below the vertical adjustment screw. The horizontal and straight section of the supporting plate can hold the bottom of the guide rail to be installed. In order to facilitate the manufacture of tooling, the support plate of the present invention is made of angle steel.

In order to better locate the side of the guide rail to be installed and prevent the guide rail to be installed from moving left and right on the pallet, the present invention is equipped with a horizontal limit component for each installation adjustment piece. The horizontal limit assembly includes a hanger, a horizontal limit rod and a horizontal limit lock nut.
