Description

Technical Field

[0001] The utility model relates to the field of connecting devices for mining transport vehicles, in particular to a universal hard connecting device for mining narrow-gauge transport vehicles. Background Art

[0002] The mining transport vehicle connection device is a mechanical device designed specifically for mining transport vehicles. It is used to achieve fast and safe connection between vehicles in mining operations to facilitate efficient material transfer. The mining narrow-gauge transport vehicle universal hard connection device is a type of mining transport vehicle connection device.

[0003] After searching, the applicant found that a Chinese patent disclosed "a universal hard connection device for mineral material vehicles", and its publication (announcement) number is "CN210234978U". When encountering a slope during use, this patent can rotate freely in the horizontal direction and in the vertical direction, ensuring that the force transmitted to the mine car by the device is along the track direction, which completely solves the problems of soft connection sagging between the vehicle and the material vehicle and between the material vehicles, the switches, rope pulleys and other ancillary facilities on the scraper track, and the material vehicle falling off the track and overturning. However, there is no automatic lubrication device inside the traditional universal hard connection device of the narrow-gauge mining transport vehicle.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0023] The "front, back, left, right" viewing angles of this device are Figure 1 The directions in the attached drawings are taken as reference.

[0024] like Figure 1-5 As shown, a universal hard connection device for a narrow-gauge transport vehicle for mining comprises two connection sleeves 1. Universal rings 2 are provided on opposite sides of the inner walls of the two connection sleeves 1 on both sides. The universal rings 2 are of the prior art structure and are used in conjunction with the ball head 12 to ensure the universal movement of the equipment. Automatic lubrication mechanisms are provided on the upper sides of the two universal rings 2.

[0025] The automatic lubrication mechanism includes an oil storage chamber 3 opened on the upper side of the universal ring 2, and an oil drip port 4 is opened at the rear of the lower side of the inner wall of the two oil storage chambers 3. The rear side of the inner wall of the two oil storage chambers 3 is provided with a liquid storage drive mechanism, and the liquid storage drive mechanism includes a drive chamber 5 opened on the rear side of the inner wall of the corresponding oil storage chamber 3. The lower side of the inner wall of the drive chamber 5 is fixedly connected to a micro oil pump body 6. The micro oil pump body 6 is a prior art device, which is a kind of micro pump. It can draw lubricating oil 16 in an external device through an input end 7 and an oil suction pipe 9 connected thereto, and then press the lubricating oil 16 into the oil storage chamber 3 through an output end 8 and an oil pressure pipe 10 connected thereto, thereby ensuring the function of replenishing the lubricating oil 16 for the equipment. An output port 12 is provided at the rear of the micro oil pump body 6. An input end 7 and an output end 8 are provided in front of the micro oil pump body 6, an oil extraction pipe 9 is fixedly connected to the rear of the input end 7, and an oil pressure pipe 10 is fixedly connected to the front of the output end 8. The interior of the universal ring 2, the interior of the oil drip port 4, the interior of the drive cavity 5 and the interior of the oil pressure pipe 10 are all filled with lubricating oil 16. By arranging an automatic lubrication mechanism and a liquid storage drive mechanism, the equipment has the function of automatically lubricating the internal structure and replenishing the lubricating liquid, avoiding the problem that there is no automatic lubrication device inside the traditional universal hard connection device of the narrow-gauge mining transport vehicle, and can conveniently lubricate the joints of the internal structure of the equipment, reduce the degree of wear of the equipment, improve the use efficiency of the equipment, increase the service life of the equipment, and greatly improve the use effect of the equipment.

[0026] like Figure 3-4As shown, in some embodiments, the rear ends of the two oil extraction pipes 9 respectively penetrate the rear side of the inner wall of the corresponding driving chamber 5 and the rear side of the inner wall of the corresponding connecting sleeve 1 and extend to the back of the corresponding connecting sleeve 1, and the front ends of the two oil pressure pipes 10 respectively penetrate the front side of the inner wall of the corresponding driving chamber 5 and extend to the rear side of the inner wall of the corresponding oil storage chamber 3, which has a better connection effect and ensures the stability and safety of the equipment during use. The left and right rear sides of the inner walls of the two oil extraction pipes 9 are fixedly connected with threaded connecting rings 11, which facilitates the connection between the equipment and the external oil supply equipment and ensures the use effect of the equipment.

[0027] like Figure 1-4 As shown, in some embodiments, the inner walls of the two universal rings 2 are provided with ball heads 12, which ensure the universal movement of the equipment and the basic use effect of the equipment. The opposite sides of the surfaces of the two ball heads 12 are commonly fixedly connected with a connecting rod 13, and the opposite sides of the two universal rings 2 are fixedly connected with connecting blocks 14. The connecting rod 13 and the connecting blocks 14 ensure the basic connection effect of the equipment. The opposite sides of the two connecting blocks 14 are fixedly connected with connecting heads 15, which ensure the connection between the equipment and the narrow-gauge mining transport vehicle. The material of the connecting sleeve 1, the material of the connecting head 15, the material of the connecting rod 13, the material of the ball head 12 and the material of the universal ring 2 are all 45 carbon steel.

[0028] The working principle of the utility model is as follows: when the lubricating oil 16 on the inner wall of the universal ring 2 is lacking (the gap between the universal ring 2 and the ball head 12 is very small, and the lubricating oil 16 will not be lost quickly), the lubricating oil 16 in the oil storage chamber 3 flows to the inner wall of the universal ring 2 through the oil dripping port 4, and the device automatically uses the lubricating oil 16 to lubricate the internal mechanism. When the lubricating oil 16 needs to be added to the oil storage chamber 3, the threaded connecting ring 11 connected to the oil extraction pipe 9 is connected to the external pipeline, and the micro oil extraction pump body 6 is started, which draws the lubricating oil 16 in the external device through the input end 7 and the oil extraction pipe 9 connected thereto. The lubricating oil 16 is then pressed into the oil storage chamber 3 through the output end 8 and the oil pressure pipe 10 connected thereto, so as to complete the function of replenishing the lubricating oil 16 for the equipment. The equipment is provided with an automatic lubrication mechanism and a liquid storage drive mechanism, so that the equipment has the functions of automatically lubricating the internal structure and replenishing the lubricating liquid, thereby avoiding the problem that the traditional universal hard connection device of the narrow-gauge mining transport vehicle has no automatic lubrication device, and can conveniently lubricate the connection of the internal structure of the equipment, thereby reducing the degree of wear of the equipment, improving the use efficiency of the equipment, increasing the service life of the equipment, and greatly improving the use effect of the equipment;

[0029] The threaded connecting ring 11 facilitates the connection between the equipment and the external oil supply equipment, ensuring the use effect of the equipment. The ball head 12 ensures the universal movement of the equipment and ensures the basic use effect of the equipment. The connecting rod 13 and the connecting block 14 ensure the basic connection effect of the equipment. The connecting head 15 ensures the connection between the equipment and the narrow-gauge mining transport vehicle.
