Description

Technical Field

[0001] The utility model relates to the technical field of preventing material accumulation in a stacker-reclaimer, and in particular to a novel anti-sticking and material-slipping ridge device for a stacker-reclaimer cantilever return stroke. Background Art

[0002] The position of the stacker-reclaimer cantilever return roller bracket is affected by the design structure, which makes it easy for material to accumulate. If it is not cleaned in time, it is easy to rub against the rollers and belts, causing equipment damage. Currently, the cleaning here is difficult and time-consuming, and there is a safety risk of working at heights. In addition, the stacker is remotely operated and unmanned, and cannot be discovered in time.

[0003] The existing boom return steel structure is designed as a multi-point triangular support. This design is conducive to increasing the stability of the boom, but at the same time there is the problem of easy accumulation of materials in the boom. If too much material is accumulated in the boom's stable support, the weight of the boom will be increased, which will affect the boom's steel structure and the pitch support cylinder. In addition, too much accumulated material can easily block the running rollers, causing excessive wear of the rollers and damage to the belts. At the same time, too much accumulated material will also pose a safety risk of falling objects from high altitudes, bringing certain safety hazards to safe production. Utility Model Content

[0007] This device can effectively prevent the accumulation of mineral powder on the boom return steel, so that the mineral powder will not cause wear between the rollers and belts, and the service life of the rollers and belts is extended. In addition, the material that slides down will fall on the receiving plate at the bottom of the boom and be collected. Later, you only need to clean the receiving plate at a low place, which can avoid the boom return steel from being overloaded, and the safety risk is greatly reduced.

[0008] Furthermore, a fixing bolt is provided between the support plates that are symmetrically distributed in pairs, and the two fixing bolts are distributed up and down and form a cross structure.

[0009] Furthermore, an angle iron is provided at the connection between the support plate and the arm return steel.

[0010] The above solution can further improve the installation stability of the device on the arm return steel by using angle steel and fixing bolts.

[0011] Furthermore, the bottom plate, hinge and support plate are all made of stainless steel.

[0012] In the above scheme, the bottom plate, hinge and support plate are all made of stainless steel to prevent corrosion and rust after contact with mineral powder.

[0013] Furthermore, the inclination angle of the bottom plate is 55-65 degrees.

[0014] Furthermore, the assisting slide plate is made of high molecular polyethylene material.

[0015] In the above scheme, the auxiliary sliding plate is made of high molecular polyethylene material, which has good impact resistance and anti-sticking properties, can resist most acid and alkali corrosion, and extend the service life of the auxiliary sliding plate.

[0016] Furthermore, a mounting groove adapted to the assisting slide plate is provided on the bottom plate, and screws are provided on the bottom plate, and the screws pass through the bottom plate and are threadedly connected to the assisting slide plate.

[0017] The above scheme can realize the installation position limitation of the auxiliary sliding plate through the installation groove, and at the same time, with the screws, the auxiliary sliding plate and the bottom plate can be quickly disassembled and replaced, which is convenient for the subsequent maintenance of the device.

[0030] The bottom plate 2, hinge 3 and support plate 4 in the present device are all made of stainless steel to prevent corrosion and rust after contact with mineral powder. Specifically, the inclination of the bottom plate 2 after installation is preferably 60 degrees, which can effectively prevent the mineral powder from accumulating on the boom return steel 7. The mineral powder is dispersed to the surroundings in the chute area and can be subsequently transferred to the receiving plate at the bottom of the boom.

At the same time, an auxiliary slide plate 1 is added to the bottom plate 2 to further improve the flow effect of the mineral powder and avoid the accumulation of mineral powder on the bottom plate 2. In addition, the support plate 4 is used to achieve stable installation between the present device and the boom return steel 7, and the angle steel is used in conjunction with the fixing bolts 6 to further improve the installation stability of the present device.

[0031] The principle of this device is to utilize the deadweight of the mineral powder when it falls, and cooperate with the inclined bottom plate 2 and the auxiliary slide plate 1 to prevent the mineral powder from forming accumulation on the boom return steel 7, and then will not contact and wear the rollers and belts, effectively extending the service life of the rollers and belts, and greatly reducing the maintenance cost; subsequent personnel can use spray water to flush the receiving plate to complete the cleaning of the accumulated materials, reducing the labor intensity and operation risks of personnel cleaning the materials.

[0032] Compared with the prior art, the device can effectively prevent the accumulation of mineral powder on the boom return steel 7, so that the mineral powder will not cause wear between the rollers and the belts, and the service life of the rollers and the belts is extended. In addition, the material that slides down will fall on the receiving plate at the bottom of the boom and be collected. Subsequently, it is only necessary to clean the receiving plate at a low place, which can avoid the boom return steel 7 from being overloaded, and the safety risk is greatly reduced.

[0033] In other embodiments, the auxiliary sliding plate 1 is made of high molecular polyethylene material; the auxiliary sliding plate 1 is made of high molecular polyethylene material with good impact resistance and anti-sticking properties, can resist most acid and alkali corrosion, and extend the service life of the auxiliary sliding plate 1.
