Description

Technical Field

[0001] The present application belongs to the technical field of power supply for mining equipment, and in particular relates to a tower-type power supply device. Background Art

[0002] Common mining equipment includes crushing machinery, mining machinery, and excavation machinery, etc. These mining equipment are generally powered by internal combustion engines or batteries.

[0003] In a related technical solution, the inventor attempted to directly power mining equipment via an external power cord. The mining equipment is equipped with an electric motor that converts electrical energy into kinetic energy. However, when using an external power cord, the mining equipment frequently moves within its operating range, and the power cord, which is connected to the ground, is prone to bending and tangling. This can even lead to the power cord becoming entangled with the mining equipment's running wheels, causing it to be torn or short-circuited.

[0004] It should be noted that the above content falls within the technical knowledge of the inventor and does not necessarily constitute prior art. Utility Model Content

[0005] The purpose of the utility model is to provide a tower power supply device, which can directly supply power to mining equipment using an external power supply line, and realize the overhead setting of the power supply line at all times during the movement of the mining equipment, so as to prevent the power supply line from hanging down to the ground and being crushed and entangled by the mining equipment.

[0006] To solve the above-mentioned problems, the present invention provides a tower-type power supply device, comprising a support tower, a fixing member, a fixed pulley, a steel wire rope, and a power supply line. The upper end of the support tower forms a support end. The fixing member is fixed to the support end; the fixed pulley is rotatably mounted on the support end. The support tower has an inner cavity with an open upper end, in which a counterweight block is provided. One end of the steel wire rope is fixed to the fixing member, and the other end forms a connecting end. The connecting end passes through the counterweight block and is supported by the fixed pulley. The connecting end extends downward relative to the fixed pulley and is used to be fixed to the mining machinery to be powered. A plurality of mounting rings are fixed at intervals on the power supply line, and the steel wire rope passes through the mounting rings in sequence. One end of the power supply line is used to electrically connect to the mining machinery to be powered, and the other end is connected to the power supply source. The middle portion of the power supply line is fixed to the support end.

[0007] The beneficial effects of one or more of the above technical solutions are:

[0008] This solution is equipped with a support tower that can suspend one end of the power line to prevent it from being squeezed by the running wheels of the mining equipment when the power line is laid flat on the ground. At the same time, this solution also provides an additional wire rope, one end of which is fixed to the support end of the support tower and the other end is fixed to the mining equipment to be powered. The middle part of the wire rope hangs down into the inner cavity of the support tower through a counterweight. Within the operating range set by the mining equipment, regardless of how the distance between the mining equipment and the support tower changes, the wire rope between the support tower and the mining equipment will be tensioned by the gravity of the counterweight, thereby preventing the wire rope from sagging and contacting the ground.

[0009] When the wire rope does not sag and contact the ground, the power line arranged on the outside of the wire rope through multiple mounting rings will also be supported by the wire rope and will not sag to the ground, thereby preventing the movement of mining equipment from entanglement and crushing the power line.

[0014] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0015] In this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0016] like Figure 1-Figure 2 As shown, this embodiment provides a tower-type power supply device, including a support tower 1, a fixing member 11, a fixed pulley 9, a steel wire rope 2, and a power supply line 8. The upper end of the support tower 1 forms a support end. The fixing member 11 is fixed to the support end; the fixed pulley 9 is rotatably mounted on the support end. The support tower 1 has an inner cavity 5 with an open upper end, in which a counterweight is provided. One end of the steel wire rope 2 is fixed to the fixing member 11, and the other end forms a connecting end. The connecting end passes through the counterweight and is supported by the fixed pulley 9. The connecting end extends downward relative to the fixed pulley 9 and is used to be fixed to the mining machinery to be powered. A plurality of mounting rings 7 are fixed at intervals on the power supply line 8. The steel wire rope 2 passes through the mounting rings 7 in sequence. One end of the power supply line 8 is used to electrically connect to the mining machinery to be powered, and the other end is connected to the power supply source. The middle portion of the power supply line 8 is fixed to the support end.

[0017] Specifically, the support tower 1 in this embodiment is a truss structure, comprising a plurality of transverse rods and vertical rods, which are fixed to each other by welding or bolting to form the truss structure. Generally, the transverse rods and vertical rods are metal rods.

[0018] See also Figure 1 As shown, in a specific structural form of the support tower 1, the support tower 1 includes a first tower section 101 and a second tower section 102 arranged vertically side by side, with a gap between the first tower section 101 and the second tower section 102. The first tower section 101 and the second tower section 102 are connected to each other by a crossbar 14. The first tower section 101, the second tower section 102, and the crossbar 14 enclose the aforementioned inner cavity 5. In this case, the cross section of the inner cavity 5 is square.

[0019] In some other embodiments, the cross section of the inner cavity 5 can be set to other shapes such as a rectangle or a regular hexagon through the specific structural setting of the support tower 1.

[0020] In this embodiment, the cross-sectional shape and size of the inner cavity 5 match the shape and size of the counterweight, and the side surfaces of the counterweight fit in contact with the inner wall of the inner cavity 5. Specifically, when the inner wall of the inner cavity 5 fits in contact with the side surfaces of the counterweight, the inner cavity 5 provides a guide function through the inner wall, preventing the counterweight from shaking under the influence of external wind and then colliding with the support tower 1.

[0021] In this embodiment, the spacing between adjacent mounting rings 7 is equal. In other embodiments, the spacing between adjacent mounting rings 7 may vary, with the spacing between the mounting rings 7 gradually increasing as the distance away from the mining equipment 12 (towards the support tower 1) increases. This arrangement can reduce the spacing between the mounting rings 7 between power lines 8 near one end of the mining equipment, thereby reducing the probability of this portion drooping on the ground.

[0022] In this embodiment, a guide wheel 10 is provided at the upper end of the inner cavity 5. The guide wheel 10 is supported by the support tower 1. One end of the guide wheel 10 facing the center of the inner cavity 5 abuts against the steel wire rope 2. Figure 1 The guide wheel 10 is rotatably connected to the bracket, and the bracket is fixedly installed on the side wall of the inner cavity 5.

[0023] In this embodiment, the counterweight is a weight 4, with a connecting lug 6 at its upper end, through which the wire rope 2 passes. Specifically, the connecting lug 6 is a semi-annular structure, with both ends of the connecting lug 6 along its circumference being fixed to the weight 4. In other embodiments, the connecting lug 6 is a gate plate, the lower end of which is fixed to the weight 4.

[0024] In this embodiment, the fixing member 11 is a fixing ring, which is fixed to the support end. Specifically, the fixing ring is fixed to the upper surface of the support end by welding or bolt connection.

[0025] In this embodiment, the axis of the connecting ear 6 is horizontal, and a curved plate 3 is fixed to the upper end of the connecting ear 6. The curved plate 3 is symmetrically arranged about the center of the connecting ear 6. Preferably, the curved plate 3 is an arc-shaped plate.

[0026] Specifically, in this embodiment, the curved plate 3 is fixed to the connecting ear 6 by bolts or welding. The curved plate 3 can limit the bending angle of the steel wire rope 2 passing through the connecting ear 6, thereby preventing the steel wire rope 2 from being damaged due to excessive bending angle.

[0027] In this embodiment, the fixed pulley 9 is connected to the support tower 1 via a mounting base 13, and the mounting base 13 is rotatable about a vertical axis relative to the support tower 1. This arrangement enables the fixed pulley 9 to rotate about a vertical axis driven by the mounting base 13, thereby adapting to the movement of mining machinery around the support tower 1.

[0028] Working principle:

[0029] When this device is used, the mining equipment 12 moves in a direction away from the support tower 1, which will pull the connecting end of the wire rope 2 away from the support tower 1. The length of the part of the wire rope 2 that penetrates the inner cavity 5 will be reduced, and then the wire rope 2 will drive the counterweight block to rise, and the gravitational potential energy at the counterweight block will increase.

[0030] When the mining equipment 12 moves toward the direction close to the support platform, the connecting end of the wire rope 2 will be prevented from loosening in the direction close to the support tower 1, and the wire rope 2 will tend to hang down to the ground in a relaxed state. At this time, the counterweight moves downward to increase the length of the wire rope 2 that penetrates the inner cavity 5, and the wire rope 2 is re-tensioned and suspended.

[0031] When the steel wire rope 2 is constantly tensioned, the power line 8, supported overhead by the steel wire rope 2, remains essentially suspended. As the mining equipment 12 moves away from the support tower 1, the distance between two adjacent mounting rings 7 of the power line 8 along the steel wire rope 2 increases. As the mining equipment 12 approaches the support tower 1, the distance between two adjacent mounting rings 7 of the power line 8 along the steel wire rope 2 decreases. In this embodiment, the power line 8 and the steel wire rope 2 are constantly suspended under the action of the counterweight.

[0032] The above are merely examples of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims of the present invention.
