[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 In this embodiment, a unloading rail installation inspection device is used to measure the distance between two unloading rails and the horizontal position of two unloading rail installations.

[0022] Specifically, it includes a sleeve 1, an extension rod 2, two connecting pieces 3 and a level 4;

[0023] The extension rod 2 is slidably connected to the inside of the sleeve 1, and a plurality of scale grooves 5 are provided on the upper surface of the extension rod 2 for measuring the distance between the left and right unloading rails; two connecting pieces 3 are respectively installed at the ends of the sleeve 1 opposite to the extension rod 2 for fitting with the upper surfaces of the two unloading rails; a level 4 is assembled on the front side of the sleeve 1 for the horizontal position of the two unloading rails.

[0024] In actual use, the connecting pieces 3 are respectively fitted to the upper end surfaces of the two unloading rails, and the two connecting pieces 3 are close to one end of the two unloading rails, and the value on the scale groove 5 at this time is recorded, and the sleeve 1 and the extension rod 2 are pushed so that the two connecting pieces 3 move toward the other end on the two unloading rails at the same time, and the value on the scale groove 5 is observed at the same time. When the extension rod 2 is pulled out from the inside of the sleeve 1 or compressed into the inside of the sleeve 1 during the movement, the corresponding values ​​of the sleeve 1 and the scale groove 5 change accordingly, indicating that the unloading rails on the left and right sides are not in a parallel state.

[0025] In addition, the state of the level meter 4 is observed during the movement to determine whether the unloading rails on the left and right sides are at the same level.

[0026] Furthermore, in order to ensure that the two connecting plates 3 can effectively fit with the two unloading rails, the front cross-section of the connecting plate 3 in this embodiment is in an inverted L-shape, and the two connecting plates 3 are arranged back to back, and in order to facilitate the movement of the two connecting plates 3 on the unloading rails, universal wheels 6 are installed on the top wall and the opposite side wall of the two connecting plates 3.

[0027] In actual use, the universal wheel 6 is provided to facilitate the movement of the inspection device from one end of the unloading rail to the other end thereof, while reducing the friction between the connecting piece 3 and the unloading rail, thereby improving the convenience of movement of the inspection device.

[0028] Furthermore, in order to fix the position of the extension rod 2 so as to adjust the distance between other parts of the two unloading rails according to the distance between one end of the two unloading rails, a fastener 7 is installed on the front side of the sleeve 1, and the fastener 7 is threadedly connected to the front side of the inner wall of the sleeve 1, and one end of the fastener 7 abuts against the extension rod 2 to fix the extension rod 2.

[0029] In actual use, the distance between the two ends of the unloading rails is recorded, and the corresponding value on the extension rod 2 is recorded, and then the fastener 7 is tightened to retain the value on the extension rod 2, and then the measuring device is moved to the other end of the two unloading rails and placed between the two unloading rails. The distance between the two unloading rails is adjusted by the value on the scale groove 5 to ensure that the distance between the two ends of the two unloading rails is the same, so that the two unloading rails are in a parallel state.

[0030] In addition, the height of one of the unloading rails is adjusted by means of a level gauge 4 so that the two unloading rails are on the same horizontal line.

[0031] In detail, in order to ensure that the two connecting plates 3 can effectively fit with the two unloading rails during the movement of the inspection device and improve the accuracy of the inspection results, a compression spring 8 is installed on the left side of the inner wall of the sleeve 1 in this embodiment, and one end of the compression spring 8 is connected to the extension rod 2.

[0032] In actual use, the elastic force of the compression spring 8 pushes the sleeve 1 and the extension rod 2 to move in opposite directions, so that the connecting pieces 3 on the sleeve 1 and the extension rod 2 are tightly fitted with the two unloading rails respectively, thereby improving the accuracy of the numerical value of the inspection device when moving.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
