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 guyed 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. Utility Model Content

[0004] The purpose of the utility model is to provide a tower-type pull-wire 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 sagging to the ground and being crushed and entangled by the mining equipment.

[0005] In order to solve the above problems, the present invention provides a tower-type wire-pulling power supply device, comprising a support tower, a drum, a power supply line and a power source, wherein the upper end of the support tower forms a support end; the drum is rotatably connected to the mounting seat, the rotation axis of the drum is horizontally arranged, the mounting seat is installed on the support end, and the rotation axis of the mounting seat is vertically arranged; one end of the power supply line is a receiving end, which is fixed to the drum, and the other end extends downward and forms a power supply end, which is used to electrically connect to the mining equipment to be powered; the power source can drive the drum to rotate and reel in the power supply line; the drum has a rotating shaft, and the rotating shaft has a wire channel connecting its own side and end faces, the receiving end of the power supply line passes through the side wall of the drum and the wire channel in sequence and then passes through the end face of the rotating shaft, an electric slip ring is fixed at the end face of the rotating shaft, the power supply line is connected to the inner ring in the electric slip ring, and the outer ring of the electric slip ring is connected to the external power line. The beneficial effects of one or more of the above technical solutions are:

[0006] This solution features a support tower with a mounting base rotatably mounted on its upper end. The mounting base's rotational axis is vertically arranged, and the mounting base is rotatably connected to a reel. The reel's rotational axis is arranged horizontally. The reel is driven by a power source, with one end of the power supply line serving as the receiving end and the other end as the power supply end. The receiving end is secured to the reel. This solution allows the power supply line between mining equipment and the support tower to be placed overhead. As the mining equipment approaches the support tower, the reel can reel in any drooping power line to maintain the overhead position.

[0007] In this solution, the overall structure composed of the drum and the mounting base can rotate around the vertical axis, which is convenient for adapting to the working condition of the mining equipment walking around the support tower within the operating range.

[0008] In this solution, the power receiving end of the power cable passes through the reel and connects to the slip ring at the end of the rotating shaft. The inner ring of the slip ring is connected to the power cable, and the outer ring is connected to the external power cable. This arrangement facilitates connection to the external power cable while the power cable is being wound through the reel. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] like Figure 1-Figure 2As shown, this embodiment provides a tower-type wire-pulling power supply device, comprising a support tower 3, a drum 1, a power supply line 4 and a power source, wherein the upper end of the support tower 3 forms a support end; the drum 1 is rotatably connected to the mounting base 2, the rotating shaft 103 of the drum 1 is horizontally arranged, the mounting base 2 is installed on the support end, and the rotating shaft 103 of the mounting base 2 is vertically arranged; one end of the power supply line 4 is a receiving end, which is fixed to the drum 1, and the other end extends downward and forms a power supply end, which is used to be electrically connected to the mining equipment 5 to be powered; the power source can drive the drum 1 to rotate and reel in the power supply line 4; the drum 1 has a rotating shaft, and the rotating shaft has a wire channel connecting its side surface and end surface, the receiving end of the power supply line 4 passes through the side wall of the drum 1 and the wire channel in sequence, and then passes through the end surface of the rotating shaft, an electric slip ring is fixed to the end surface of the rotating shaft, the power supply line 4 is connected to the inner ring 105 in the electric slip ring, and the outer ring 102 of the electric slip ring is connected to the external power line.

[0017] Specifically, the support tower 3 in this embodiment is a truss structure, comprising a plurality of transverse rods, vertical rods, and diagonal braces, which are fixed to each other by welding or bolting to form the truss structure. Generally, the transverse rods, vertical rods, and diagonal braces are metal rods.

[0018] In some other embodiments, in order to increase the structural stability of the support tower 3, the support tower 3 has a structure that is narrow at the top and wide at the bottom.

[0019] Specifically, in order to facilitate the installation of components such as the mounting base 2 , a top plate 104 is fixed to the upper end of the support tower 3 , and the top plate 104 is fixed to the main structure of the support tower 3 by welding or bolts.

[0020] In this embodiment, the reel 1 is composed of a cylinder 101 and a rotating shaft, and the cylinder 101 and the rotating shaft are detachably fixed.

[0021] Specifically, annular plates are coaxially fixed to both ends of the cylinder 101 , and a winding space is enclosed between the end faces of the two annular plates and the outer ring 102 surface of the cylinder 101 . The winding space is used to wind the rolled power line 4 .

[0022] Specifically, the cylinder 101 and the rotating shaft are fixed by bolts or positioning pins.

[0023] In some other embodiments, the cylinder 101 and the rotating shaft can be formed in an integral structure, or the two can be fixed by welding.

[0024] In this embodiment, a vertical rotation shaft 103 is fixed to the upper end of the support tower 3, and a vertical rotation hole is provided in the mounting base 2, and the rotation shaft 103 is rotatably connected to the rotation hole. Here, the rotation shaft is inserted into the rotation hole, and the two are coaxially arranged.

[0025] In this embodiment, a bearing is provided between the outer wall of the rotating shaft 103 and the inner wall of the rotating hole. The inner ring of the bearing is in contact with the outer ring 102 of the rotating shaft, and the outer ring of the bearing is in contact with the inner ring 105 of the rotating hole.

[0026] In this embodiment, the support tower 3 comprises a main body and a lifting platform positioned above the main body, with a lifting drive disposed between the main body and the lifting platform. Specifically, the lifting drive may be an electric push rod, hydraulic cylinder, or pneumatic cylinder. This arrangement allows the height of the upper end of the support tower 3 to be varied through the structural arrangement of the lifting drive, thereby providing a high overhead height during use and allowing the height to be lowered for easier transport during transit.

[0027] In some embodiments, a plurality of running wheels are provided at the lower end of the support tower 3 , and the support tower 3 is driven to move by the running wheels.

[0028] In some configurations, the power source is a drive motor, the output shaft of which is coaxially fixed to the rotating shaft of the reel 1, and the housing of the drive motor is fixed to the support tower 3. In this case, if the mining equipment 5 moves toward the support tower 3, the drive motor drives the reel 1 to reel; if the mining equipment 5 moves away from the support tower 3, the drive motor is de-energized, and the pulling of the mining equipment 5 drives the power supply line 4 to unwind from the reel 1.

[0029] The power source here can be replaced by a pneumatic motor instead of a drive motor. The installation and use of the pneumatic motor can be referred to the drive motor and will not be repeated here.

[0030] In other structural forms, the power source is a torsion spring, which is mounted on the outside of the rotating shaft. The torsion spring has two output ends, one of which abuts against the rotating shaft, and the other abuts against the mounting base 2. During use, if the mining equipment 5 moves away from the support tower 3, the torsion spring is twisted and tightened to store elastic potential energy. If the mining equipment 5 moves toward the support tower 3, the torsion spring is twisted and loosened to release elastic potential energy. The action of the torsion spring drives the rotating shaft to rotate, thereby driving the winding drum 1.

[0031] Working principle:

[0032] When the mining equipment 5 moves in a direction away from the support tower 3, the reel 1 unwinds so that the length of the power line 4 between the reel 1 and the mining equipment 5 increases synchronously. The unwinding of the reel 1 can adapt to the movement of the mining equipment 5 away.

[0033] When the mining equipment 5 moves toward the support tower 3 , the distance between the drum 1 and the mining equipment 5 becomes smaller. In order to prevent the power line 4 between the two from sagging to the ground, the drum 1 is used to reel in the power line 4 .

[0034] When the mining equipment 5 moves around the support tower 3 within the operating range, in order to ensure that the reel 1 can reel in the power line 4 , the reel 1 can rotate around the vertical axis under the pull of the power line 4 .

[0035] 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.
