Description

Technical Field

[0001] This utility model relates to the technical field of semi-submersible bucket wheel stacker-reclaimers, and in particular to a mechanical support device for semi-submersible bucket wheel stacker-reclaimers. Background Technology

[0002] Bucket wheel stacker-reclaimers, commonly known as bucket wheel excavators, are large-scale bulk material conveying equipment, and hydraulic semi-submersible tail cars are a common component of their tail cars. Semi-submersible bucket wheel stacker-reclaimers are widely used in mining, ports, thermal power plants, steel mills, cement plants, chemical plants, and other enterprises as one of the main pieces of equipment for bulk material conveying. Bucket wheel stacker-reclaimers are simple to operate and easily automated. Currently, the tail cars of semi-submersible bucket wheel stacker-reclaimers use hydraulic cylinders to adjust the position of the stacked and reclaimed materials, and use a positioning signal as a fixed position. During the use of semi-submersible bucket wheel stacker-reclaimers, the following problems have been found when using hydraulic cylinders for support: 1. When the stacked position is maintained for a long time, slow leakage from the cylinders can cause the tail car height to decrease, affecting the change in the stacked position; 2. When the stacked position is maintained, the entire machine vibrates when the trolley moves, causing the positioning signal to be lost. Since the positioning signal is a fixed position, the logic does not allow the loss of the positioning signal, resulting in a stop; 3. The imbalance of the belt conveyor on the tail car caused by the asynchrony of the two hydraulic cylinders leads to the belt of the bucket wheel stacker tail car running off-center. Utility Model Content

[0003] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a mechanical support device for a semi-submersible bucket wheel stacker-reclaimer to solve the existing problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A mechanical support device for a semi-submersible bucket wheel stacker-reclaimer includes a positioning component and a support component abutting against the positioning component; the positioning component is fixedly installed on the gantry of the semi-submersible bucket wheel stacker-reclaimer, and the support component is fixedly installed on the tail car of the semi-submersible bucket wheel stacker-reclaimer.

[0006] Preferably, the positioning component is L-shaped and includes a mounting base, a support column, and a first support block. One end of the mounting base is fixedly connected to the door seat, and the other end of the mounting base is fixedly connected to one end of the support column. The other end of the support column is fixedly connected to the first support block.

[0007] Preferably, the support assembly is T-shaped and includes a support rod and a second support block. One end of the support rod is fixedly connected to the stacking and reclaiming end of the tail vehicle, and the other end of the support rod is fixedly connected to the second support block, which abuts against the first support block.

[0008] The beneficial effects of this utility model are as follows: By setting a positioning component on the gantry and a support component at the stacking and reclaiming end of the tail car, mechanical support is added between the gantry and the tail car, avoiding the problem of slow leakage of the hydraulic cylinder causing the tail car height to drop and affecting the change of the stacking position, as well as the problem of the equipment stopping due to the loss of the positioning signal caused by the movement of the trolley when the stacking position is reached, and solving the problem of tail car conveyor belt deviation caused by hydraulic cylinder asynchrony; the structural design of this application is simple, reduces costs, and can completely solve the problems of deviation caused by material point change due to position change, equipment stopping due to loss of limit signal, and tail car conveyor belt deviation caused by hydraulic cylinder asynchrony.

[0013] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. 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.

[0014] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] 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 the internal connection of 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.

[0016] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] Please see Figure 1-2 A mechanical support device for a semi-submersible bucket wheel stacker-reclaimer includes a positioning component 1 and a support component 5 abutting against the positioning component 1; the positioning component 1 is fixedly installed on the gantry 8 of the semi-submersible bucket wheel stacker-reclaimer, and the support component 5 is fixedly installed on the tail carriage 11 of the semi-submersible bucket wheel stacker-reclaimer.

[0018] Furthermore, the positioning component 1 is L-shaped and includes a mounting base 2, a support column 3, and a first support block 4. One end of the mounting base 2 is fixedly connected to the door seat 8, and the other end of the mounting base 2 is fixedly connected to one end of the support column 3. The other end of the support column 3 is fixedly connected to the first support block 4.

[0019] Furthermore, the support component 5 is T-shaped and includes a support rod 6 and a second support block 7. One end of the support rod 6 is fixedly connected to the stacking and reclaiming end of the tail car 11, and the other end of the support rod 6 is fixedly connected to the second support block 7. The second support block 7 abuts against the first support block 4.

[0020] The tail carriages of current semi-submersible bucket wheel stacker-reclaimers are almost all of the same type, using hydraulic cylinders 10 to adjust the displacement of stacking and reclaiming materials, and using the position signal as the fixed position point. In use, the gantry 8 is disengaged from the tail carriage 11, and then the tail carriage 11 is raised to the material stacking and reclaiming displacement position. After that, the gantry 8 is hooked back into place with the tail carriage 11, at which point the tail carriage 11 is in the material stacking and reclaiming position. However, if the tail carriage 11 is in the material stacking and reclaiming position for a long time, slow leakage of the hydraulic cylinder 10 will cause the height of the tail carriage 11 to drop, affecting the change of the stacking position. Furthermore, when the trolley is in the stacking position, if the trolley travels and the equipment trips, the logic does not allow the tripping of the position signal to be lost, as the position signal is used as the fixed position.

[0021] This application discloses a mechanical support device for a semi-submersible bucket wheel stacker-reclaimer. By setting a positioning component on the gantry and a support component at the stacking / reclaiming end of the tail car, mechanical support is added between the gantry and the tail car. This avoids the problems caused by slow leakage of the hydraulic cylinders leading to a decrease in the height of the tail car and affecting the change of the stacking position, the problem of equipment tripping due to loss of the positioning signal caused by the movement of the main trolley when the stacking position is reached, and the problem of tail car conveyor belt deviation caused by asynchrony of the hydraulic cylinders. The structure of this application is simple, reduces costs, and can completely solve the problems of deviation caused by changes in the material point due to position changes, equipment tripping due to loss of the limit signal, and tail car conveyor belt deviation caused by asynchrony of the hydraulic cylinders.

[0022] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0023] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
