[0024] The technical solution of this utility model patent will be clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] See attached document Figure 1-3 The stacker-reclaimer tail car tie rod fixing device of this utility model includes: a first fixing base 1, a second fixing base 2, and a tie rod 3; wherein,
[0028] Two first fixed bases 1 are symmetrically installed on the belt idler support beam of the first-stage tail car, respectively located on both sides of the belt of the first-stage tail car; two second fixed bases 2 are symmetrically installed on the L-shaped beam of the first-stage tail car; the tie rod 3 includes a first steel pipe 4 and a second steel pipe 5; one end of the first steel pipe 4 is welded with an ear plate and hinged to the second fixed base 2, and the other end is welded to the second steel pipe 5; the outer surface of the second steel pipe 5 is threaded, and its end away from the first steel pipe 4 is connected and fixed to the first fixed base 1 by two locking nuts 6.
[0029] In this embodiment, two tie rods 3 are inclined and parallel. The first steel pipe 4 is a seamless steel pipe with L=5605, φ=159, and δ=20, and the second steel pipe 5 is a tapped solid steel pipe with M90*6.
[0030] The base plate of the first fixed base 1 is welded and fixed to the belt roller support beam of the first-stage tail car. Two triangular stiffeners are provided on its upper surface. An inclined limiting plate is provided above the two stiffeners. A U-shaped slot is provided on the limiting plate. The end of the second steel pipe 5 away from the first steel pipe 4 is located in the U-shaped slot. Two locking nuts 6 are located on both sides of the limiting plate and can be used to adjust the length of the pull rod 3 and lock the L-shaped beam of the first-stage tail car.
[0031] To facilitate adjustment of the tilt angle of the pull rod 3 and allow one end of the pull rod 3 to smoothly enter the U-shaped slot on the first fixed base 1, the second fixed base 2 in this embodiment is provided with two hinge plates that cooperate with the ear plates. The ear plates are placed between the two hinge plates, and then a pin is used to pass through the two hinge plates and the corresponding ear plates, allowing the pull rod 3 to rotate around the second fixed base 2.
[0032] In the actual installation process, the position of the first fixed base 1 at the lower end must first be determined. After adjusting the angle of the U-shaped slot, welding assembly is carried out, and reinforcing plates are welded for reinforcement. The position of the second fixed base 2 at the upper end is measured on site and marked with a marker pen. The second fixed base 2 at the determined position is then welded.
[0033] During the process of adjusting the length of the tie rod 3, the tie rod 3 is first installed between the first fixed base 1 and the second fixed base 2. Then, by adjusting the locking nut 6, the second steel pipe 5 is locked in the U-shaped slot, so that the tie rod 3 can be tightened to the first-stage tail car.
[0034] It is important to note that the connection line between the first fixed base 1 and the second fixed base 2, located on the same side of the belt, should be kept as parallel as possible to the center line of the first-stage tail vehicle to ensure that the tie rod is only subjected to axial force. When installing and adjusting the length of the tie rod 3, try to ensure that the lengths of the two tie rods 3 are the same to ensure that the force on the two tie rods 3 is even.
[0035] In addition, the first fixed base 1 should be lower than the first-stage tail car idler bracket to avoid affecting the normal operation of the first-stage tail car belt; when welding, attention should be paid to the surrounding environment, fire prevention measures should be taken, and the ground belt of the stacker-reclaimer and the on-machine cables should be avoided; all welding and anti-corrosion processes should meet the standard requirements.
[0036] The stacker-reclaimer first-stage tail car tie rod fixing device of this utility model can eliminate the belt conveyor deviation caused by the center line offset of the stacker-reclaimer tail car during operation, reduce the problem of belt conveyor deviation and shutdown caused by the shaking of the stacker-reclaimer tail car, improve production efficiency, and facilitate the management of material blockage in the stacker-reclaimer. It is very practical and has good market application prospects.
[0037] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations. The scope of the present invention is intended to be defined by the claims and their equivalents.
