Description

Technical Field

[0001] This utility model relates to the field of intelligent robot technology, specifically to an intelligent robot for pushing carts in mining yards. Background Technology

[0002] In modern mining operations, the mine yard serves as a crucial hub for ore transportation and transshipment, and the operational efficiency and reliability of its equipment directly impact the overall production efficiency of the mine. The car pusher, as the core equipment for automated mine car transportation in the mine yard, plays a vital role in improving transportation efficiency and reducing labor costs. Currently, the most widely used car pushers in mine yards mainly include hydraulic pin-tooth pushers and wire rope pushers.

[0003] The hydraulic power source of a hydraulic pin-tooth type trolley pusher is fixed in location, usually close to the hydraulic drive device. This limits the pushing distance. For long-distance pushing, the number of intermediate trolley sections needs to be increased, or a relay-style pushing method with an additional hydraulic drive device needs to be used to achieve long-distance pushing. This significantly increases the system complexity and maintenance difficulty, and reduces the stability and reliability of the equipment. Wire rope type trolley pushers require multiple wire rope tensioning devices and guide wheels, which is relatively cumbersome. Therefore, this patent proposes an intelligent robot for pushing trolleys in mining areas to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent robot for pushing carts in mining yards to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mining car yard trolley intelligent robot, comprising a front shunting section, a front pushing section, multiple drive trolley sections, a lithium battery storage section, a transmission rack, a rear pushing section, a rear shunting section, a trolley running track, a track liner, and a wireless communication system. The trolley running track is set on the track liner. The front shunting section, the front pushing section, the drive trolley sections, the lithium battery storage section, the rear pushing section, and the rear shunting section are all set on the trolley running track and can move along it. The front and rear shunting sections are located at the front and rear ends, respectively. The front pushing section is set adjacent to the front shunting section, and the rear pushing section is set adjacent to the rear shunting section. The lithium battery storage section and multiple drive trolley sections are located between the front and rear pushing sections, and the multiple drive trolley sections are evenly distributed according to the shunting situation. The wireless communication system is used to realize signal transmission between the various parts of the trolley intelligent robot and with the external control system.

[0006] Preferably, both the front and rear shunting sections are equipped with pull claws, and both the front and rear push sections are equipped with push claws.

[0007] Preferably, the head shunting section and the tail shunting section have the same structure, both including a section body, a claw mounted on the section body, and a shunting section drive device for controlling the movement of the claw. The shunting section drive device is connected to the wireless communication system.

[0008] Preferably, the front and rear trolley sections have the same structure, each including a section body, push claws mounted on the section body, and a trolley section drive device for controlling the movement of the push claws. The trolley section drive device is connected to a wireless communication system.

[0009] Preferably, the drive trolley section includes a section body, a drive motor mounted on the section body, a transmission gear, and traveling wheels for supporting the section body to move on the trolley running track. The output shaft of the drive motor is connected to the transmission gear, the transmission gear meshes with the transmission rack, and the drive motor is connected to the wireless communication system signal.

[0010] Preferably, the lithium battery storage section includes a section body and a lithium battery pack disposed within the section body. The lithium battery pack is used to power various electrical components of the pushcart intelligent robot. The lithium battery pack is connected to a wireless communication system to enable power monitoring and charging control.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By placing the head shunting section and the tail shunting section at the beginning and end of the locomotive respectively, with the head pusher section adjacent to the head shunting section and the tail pusher section adjacent to the tail shunting section, bidirectional pushing and shunting operations can be achieved. The drive trolley sections are evenly distributed according to the shunting conditions (number of shunting cars, shunting distance, driving torque), using a gear and rack drive system. When pushing (or shunting) is required, the trolley sections can be automatically driven to rotate forward, driven by the transmission gears and racks, propelling the trolley in the direction of travel. When the trolley reaches the point where it is to be pushed (or shunted), the trolley will automatically move forward. After adjusting the position of the mine car, the push claw (or pull claw) of the pusher (or shunting) section automatically opens, and the mine car is pushed (or transported) in the identified direction. Driven by the meshing of transmission gears and transmission racks, it can adapt to the pusher requirements of any length, is not affected by the location of the power source, and can achieve long-distance pusher. Furthermore, the pusher is achieved by multiple drive trolley sections working in conjunction with the transmission racks. The structure is relatively simple, without the need for complex hydraulic relay devices and numerous wire rope auxiliary components. The drive trolley sections and other components are relatively independent, making maintenance more convenient. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In modern mining operations, the mine yard serves as a crucial hub for ore transportation and transshipment, and the operational efficiency and reliability of its equipment directly impact the overall production efficiency of the mine. The car pusher, as the core equipment for automated mine car transportation in the mine yard, plays a vital role in improving transportation efficiency and reducing labor costs. Currently, the most widely used car pushers in mine yards include hydraulic pin-tooth pushers and wire rope pushers. The hydraulic power source of existing hydraulic pin-tooth pushers is fixed in location, usually close to the hydraulic drive unit. This limits the pushing distance, requiring the addition of intermediate pusher sections or relay-style pushing with additional hydraulic drive units for long-distance pushing. This significantly increases system complexity and maintenance difficulty, reducing equipment stability and reliability. Wire rope pushers require multiple wire rope tensioning devices and guide pulleys, making them relatively cumbersome.

[0020] like Figures 1-4As shown, this utility model provides a technical solution: an intelligent robot for pushing cars in a mining yard, including a front shunting section 1, a front pushing section 2, multiple drive trolley sections 3, a lithium battery storage section 4, a transmission rack 5, a rear pushing section 6, a rear shunting section 7, a trolley running track 8, a rail liner 9, and a wireless communication system. The trolley running track 8 is set on the rail liner 9; the front shunting section 1, the front pushing section 2, the drive trolley sections 3, the lithium battery storage section 4, the rear pushing section 6, and the rear shunting section 7 are all set on... The trolley runs on track 8 and can move along it; the head shunting section 1 and the tail shunting section 7 are located at the head and tail ends respectively, the head pusher section 2 is set next to the head shunting section 1, and the tail pusher section 6 is set next to the tail shunting section 7. The lithium battery storage section 4 and multiple drive trolley sections 3 are located between the head pusher section 2 and the tail pusher section 6, and the multiple drive trolley sections 3 are evenly distributed according to the shunting situation; the wireless communication system is used to realize the signal transmission between the various parts of the pusher robot and with the external control system.

[0021] It should be noted that by placing the head shunting section 1 and the tail shunting section 7 at the head and tail ends respectively, with the head push section 2 placed next to the head shunting section 1 and the tail push section 6 placed next to the tail shunting section 7, bidirectional pushing and shunting operations can be achieved; the drive trolley section 3 is evenly distributed according to the shunting conditions (number of shunting cars, shunting distance, driving torque).

[0022] like Figures 1-3 As shown, both the front shunting section 1 and the rear shunting section 7 are equipped with claws, and both the front pusher section 2 and the rear pusher section 6 are equipped with pushers. The front shunting section 1 and the rear shunting section 7 have the same structure, each including a section body, claws mounted on the section body, and a shunting section drive device for controlling the claw's movement. The shunting section drive device is connected to the wireless communication system. The front pusher section 2 and the rear pusher section 6 have the same structure, each including a section body, pushers mounted on the section body, and a pusher section drive device for controlling the pusher's movement. The pusher section drive device is connected to the wireless communication system. The drive trolley section 3 includes a section body, a drive motor mounted on the section body, a transmission gear, and traveling wheels for supporting the section body's movement on the trolley running track 8. The output shaft of the drive motor is connected to the transmission gear, which meshes with the transmission rack 5. The drive motor is connected to the wireless communication system. The lithium battery storage section 4 includes a section body and a lithium battery pack housed within the section body. The lithium battery pack powers various electrical components of the pushcart intelligent robot and is connected to a wireless communication system to enable power monitoring and charging control.

[0023] It is important to note that by employing a rack and pinion drive system, when pushing (or shunting) a trolley, the trolley section 3 can be automatically driven to rotate forward. Through the action of the transmission gears and racks 5, the trolley moves in the direction of travel. When the trolley reaches the position of the ore car to be pushed (or shunted), the pusher (or puller) of the trolley (or shunting) section automatically opens, pushing (or shunting) the ore car in the identified direction. Driven by the meshing of the transmission gears and racks 5, it can adapt to the need for pushing trolleys of any length, regardless of the location of the power source, enabling long-distance pushing. Furthermore, the trolley is pushed by multiple drive sections 3 in conjunction with the racks 5, resulting in a relatively simple structure. Without the need for complex hydraulic relay devices and numerous steel wire rope auxiliary components, the drive trolley section 3 and other components are relatively independent, making maintenance more convenient. In addition, positioning sensors are installed next to the mine car's travel track. The positioning sensors are used to detect the position information of the mine car and transmit the position information to the control system of the intelligent robot pushing the car through the wireless communication system to achieve precise control of pushing or shunting actions. The wireless communication system includes a wireless transmitting module and a wireless receiving module. The wireless transmitting module is set on each trolley section, and the wireless receiving module is set on the external control system and the positioning sensors used to monitor the position of the mine car, realizing bidirectional data transmission.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
