Description

Technical Field

[0001] The utility model belongs to the technical field of mine unloading stations, in particular to an auxiliary pushing device for an unloading station. Background Art

[0002] An unloading station is a place in a mine transportation system for centralized ore placement. In order to transport the ore stored in the unloading station, it is often necessary to use mine cars for transportation. In order to facilitate the unloading of ore by large mine cars, the existing unloading stations are designed in the form of curved track side unloading stations, bottom side unloading stations, bottom unloading stations and other commonly used unloading stations to meet the transportation needs of the ore.

[0003] However, the existing unloading stations generally do not have a pushing device when using mine cars to transport ore. They mainly rely on the horizontal component of the inclined curved rails and the weight of the mine car to push the mine car. The mine car moves down with its own weight to complete daily unloading. Therefore, when the traditional unloading station only relies on the weight of the mine car to transport ore, the mine car is not stable enough during operation and transportation, and the mine car is easily stuck on the conveying roller, affecting the unloading efficiency of the mine car passing through the unloading station. Utility Model Content

[0004] The purpose of the utility model is to provide an auxiliary pushing device for an unloading station to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0005] Provided is an auxiliary pushing device for an unloading station, comprising a base, a pushing mechanism being arranged on the base, a telescopic end of the pushing mechanism being connected to a first connecting rod via a first rotating pair, a second connecting rod being connected to the first connecting rod via a second rotating pair, an end of the first connecting rod away from the pushing mechanism being rotatably connected to a first support via a first sliding bearing, an end of the second connecting rod away from the first connecting rod being connected to a motor mounting seat via a third rotating pair, and an end of the motor mounting seat away from the second connecting rod being rotatably connected to the first support via a second sliding bearing;

[0006] The motor mounting seat is provided with a driving mechanism, and an output end of the driving mechanism is fixedly connected to an auxiliary wheel mechanism;

[0007] When the mine car drives into the unloading station, the driving mechanism starts, the auxiliary wheel mechanism starts to run, and drives the auxiliary wheel mechanism to start rotating. The first connecting rod is pushed to rotate around the first sliding bearing through the telescopic pushing mechanism, and then the second connecting rod is pushed to rotate through the second rotating pair. The second connecting rod then pushes the motor mounting seat to rotate around the second sliding bearing through the third rotating pair. At this time, the auxiliary wheel mechanism has not yet contacted the mine car carriage. When the mine car carriage contacts the auxiliary wheel mechanism, the auxiliary wheel mechanism will be squeezed outward, and the pushing mechanism will be squeezed back to about half of the stroke by external force, driving the mine car to move forward. When the mine car drives away, the auxiliary pushing device is closed to ensure the smooth movement of the mine car, effectively improve the unloading efficiency of the mine car passing through the unloading station, and avoid track jamming.

[0008] Furthermore, the pushing mechanism includes a cylinder mounting seat, the cylinder mounting seat is connected to the cylinder through a fourth rotating pair, the telescopic end of the cylinder is connected to the first connecting rod through a first rotating pair, the telescopic end of the cylinder is telescoped, pushing the first connecting rod to rotate around the first sliding bearing, and then pushing the second connecting rod to rotate through the second rotating pair, and the second connecting rod pushes the motor mounting seat to rotate around the second sliding bearing through the third rotating pair, so that the auxiliary wheel mechanism moves a certain distance, and when the mine car carriage contacts the auxiliary wheel mechanism, the auxiliary wheel mechanism will apply a larger positive pressure and friction force to the mine car carriage, driving the mine car to move forward.

[0009] Furthermore, a supporting diagonal steel is provided between the cylinder mounting seat and the base. By adding the supporting diagonal steel, the structural rigidity of the entire device is enhanced, thereby reducing the torsion and tilting that may occur during operation.

[0010] Furthermore, the auxiliary wheel mechanism includes a flange, a keyway is provided on the flange, an output end of the reducer is fixedly connected in the keyway, and an auxiliary wheel body is provided under the flange. The detachable connection mode enables the auxiliary wheel body to be replaced according to the requirements of different mining cars or working conditions, thereby enhancing the adaptability of the system.

[0011] Furthermore, the auxiliary wheel body is detachably connected to the bottom of the flange. The detachable connection mode enables the auxiliary wheel body to be replaced according to the requirements of different mining vehicles or working conditions, thereby enhancing the adaptability of the system.

[0012] Furthermore, a support wheel is provided on one side below the motor mounting seat, and the support wheel is slidably connected to the base. When the driving motor is started, power is transmitted to the flange through the reducer, and then the flange drives the auxiliary wheel body to rotate. The auxiliary wheel body starts to rotate, and when the mine car carriage contacts the auxiliary wheel body, friction and positive pressure are generated to push the mine car forward. When the mine car drives out, the driving motor is turned off and the auxiliary wheel body stops rotating.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] A number of auxiliary pushing devices of the unloading station are symmetrically installed on both sides of the unloading station. When the mine car enters the unloading station, the driving mechanism starts, the auxiliary wheel starts to run, and the auxiliary wheel mechanism starts to rotate. The first connecting rod is pushed to rotate around the first sliding bearing through the telescopic pushing mechanism, and then the second connecting rod is pushed to rotate through the second rotating pair. The second connecting rod then pushes the motor mounting seat to rotate around the second sliding bearing through the third rotating pair. At this time, the auxiliary wheel mechanism has not yet contacted the mine car carriage. When the mine car carriage contacts the auxiliary wheel mechanism, the auxiliary wheel mechanism will be squeezed outward, and the pushing mechanism will be squeezed back to about half of the stroke by external force. At this time, the auxiliary wheel mechanism will apply a large positive pressure and friction force to the mine car carriage, driving the mine car to move forward. When the mine car drives away, the auxiliary pushing device is closed. The auxiliary pushing device can ensure the smooth movement of the mine car, effectively improve the unloading efficiency of the mine car passing through the unloading station, and avoid the track jam phenomenon.

Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-6As shown, in the embodiment of the utility model, an auxiliary pushing device for an unloading station includes a base 1. During use, the base 1 is a plurality of symmetrically arranged unloading stations 100. A pushing mechanism 2 is arranged on the base 1. The telescopic end of the pushing mechanism 2 is connected to a first connecting rod 3 through a first rotating pair 111. The first connecting rod 3 is connected to a second connecting rod 4 through a second rotating pair 112. The end of the first connecting rod 3 away from the pushing mechanism 2 is rotatably connected to the first support 5 through a first sliding bearing 211. The end of the second connecting rod 4 away from the first connecting rod 3 is connected to a motor mounting seat 6 through a third rotating pair 113. The end of the motor mounting seat 6 away from the second connecting rod 4 is rotatably connected to the first support 5 through a second sliding bearing 212. The connecting rod mechanism formed by the first connecting rod 3 and the second connecting rod 4 can increase the thrust transmitted to the motor mounting seat 6 by the pushing mechanism 2 through the lever principle, and at the same time increase the rotation stroke of the motor mounting seat 6.

[0030] A driving mechanism 7 is disposed on the motor mounting seat 6, and an auxiliary wheel mechanism 8 is fixedly connected to the output end of the driving mechanism 7;

[0031] A plurality of auxiliary pushing devices of the unloading station are symmetrically installed on both sides of the unloading station 100. The base 1 is fixedly connected to the unloading station 100. When the mine car enters the unloading station 100, the driving mechanism 7 is started, the auxiliary wheel mechanism 8 starts to run, and the auxiliary wheel mechanism 8 starts to rotate. The first connecting rod 3 is pushed to rotate around the first sliding bearing 211 by the telescopic pushing mechanism 2, and then the second connecting rod 4 is pushed to rotate through the second rotating pair 112. The second connecting rod 4 then pushes the motor mounting seat 6 to rotate around the second sliding bearing 212 through the third rotating pair 113. At this time, the auxiliary wheel mechanism 8 has not yet contacted the mine car carriage. When the mine car carriage contacts the auxiliary wheel mechanism 8, the auxiliary wheel mechanism 8 will be squeezed outward, and the pushing mechanism 2 is squeezed back to about half of the stroke by external force. At this time, the auxiliary wheel mechanism 8 will apply a large positive pressure and friction force to the mine car carriage to drive the mine car forward. When the mine car drives away, the auxiliary pushing device is closed. The auxiliary pushing device can ensure the smooth movement of the mine car, effectively improve the unloading efficiency of the mine car passing through the unloading station 100, and avoid the track jamming phenomenon.

[0032] In one embodiment, see Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the pushing mechanism 2 includes a cylinder mounting seat 21, and a cylinder 22 is connected to the cylinder mounting seat 21 through a fourth rotating pair 114. The telescopic end of the cylinder 22 is connected to the first connecting rod 3 through the first rotating pair 111. The telescopic end of the cylinder 22 is extended and retracted, pushing the first connecting rod 3 to rotate around the first sliding bearing 211, and then pushing the second connecting rod 4 to rotate through the second rotating pair 112. The second connecting rod 4 then pushes the motor mounting seat 6 to rotate around the second sliding bearing 212 through the third rotating pair 113, so that the auxiliary wheel mechanism 8 moves a certain distance. When the mine car carriage contacts the auxiliary wheel mechanism 8, the auxiliary wheel mechanism 8 will be squeezed outward, and the pushing mechanism 2 is squeezed back to about half of the stroke of the cylinder 22 by external force. At this time, the auxiliary wheel mechanism 8 will apply a large positive pressure and friction force to the mine car carriage to drive the mine car forward. When the mine car drives out, the cylinder 22 retreats and the driving mechanism 7 is closed. The auxiliary pushing device can ensure the smooth movement of the mine car, effectively improve the unloading efficiency of the mine car passing through the unloading station 100, and avoid the track jamming phenomenon.

[0033] In one embodiment, see Figure 1 and Figure 2 As shown, a supporting diagonal steel 23 is also provided between the cylinder mounting seat 21 and the base 1. The supporting diagonal steel 23 provides additional structural support and stability. By adding the supporting diagonal steel 23, the structural rigidity of the entire device is enhanced, reducing the torsion and tilting that may occur during operation.

[0034] In one embodiment, see Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the drive mechanism 7 includes a drive motor 71, which is arranged on a motor mounting seat 6. The output end of the drive motor 71 is fixedly connected to the input end of a reducer 72, and the output end of the reducer 72 is fixedly connected to an auxiliary wheel mechanism 8. When the system is started, the drive motor 71 starts to run and generates rotational power. The output end of the drive motor 71 transmits the rotational power to the input end of the reducer 72. The reducer 72 converts the high-speed and low-torque output of the drive motor 71 into a low-speed and high-torque output. This process ensures that the auxiliary wheel mechanism 8 has sufficient driving force at a lower speed. The output end of the reducer 72 is fixedly connected to the auxiliary wheel mechanism 8, and the converted power is transmitted to the auxiliary wheel mechanism 8 to rotate it. The auxiliary wheel mechanism 8 contacts the mine car carriage traveling on the unloading station 100, and pushes the mine car forward through friction and positive pressure.

[0035] In one embodiment, see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the auxiliary wheel mechanism 8 includes a flange 81, a keyway 82 is provided on the flange 81, the output end of the reducer 72 is fixedly connected in the keyway 82, and an auxiliary wheel body 83 is provided below the flange 81. The design of the flange 81 and the keyway 82 ensures a stable connection between the reducer 72 and the auxiliary wheel body 83 to prevent slipping during high-load operation. The drive motor 71 is started, and power is transmitted to the flange 81 through the reducer 72, and the flange 81 drives the auxiliary wheel body 83 to rotate. The auxiliary wheel body 83 starts to rotate. When the mine car carriage contacts the auxiliary wheel body 83, friction and positive pressure are generated to push the mine car forward. When the mine car drives out, the drive motor 71 is turned off and the auxiliary wheel body 83 stops rotating.

[0036] In one embodiment, see Figure 1 and Figure 3 As shown, the auxiliary wheel body 83 is detachably connected to the bottom of the flange 81, and the auxiliary wheel body 83 and the flange 81 are connected by bolt connection, snap connection or other detachable fixing methods. The detachable connection method allows the auxiliary wheel body 83 to be replaced according to the requirements of different mining cars or working conditions, thereby enhancing the adaptability of the system.

[0037] In one embodiment, see Figure 1 As shown in Figure 2, a support wheel 61 is also provided on one side below the motor mounting seat 6. The support wheel 61 is slidably connected to the base 1. When the pushing mechanism 2 drives the connecting rod mechanism to move, the motor mounting seat 6 will also move accordingly. The support wheel 61 provides stable support when the motor mounting seat 6 moves, reduces the resistance and wear of the motor mounting seat 6 during the movement, ensures its smooth movement, and at the same time reduces the structural load caused by the weight of the drive motor 71 and the reducer 72.

[0038] In one embodiment, see Figure 1 and Figure 6 As shown, in addition, a signal detector (not shown in the figure) is also provided at the unloading station 100, such as an infrared sensor, a magnetic sensor, etc. In a specific embodiment, the signal detector is an infrared sensor, which is provided on the unloading station 100 to detect the position information of the mine car. There are two infrared sensor detection devices, which are respectively installed at the entry end and the exit end of the mine car, to detect the position of the mine car and send out a corresponding control signal, which is received by the external operating system to start or shut down the entire auxiliary pushing device.

[0039] In one embodiment, see Figure 1 , Figure 2 and Figure 3As shown, the air pressure of the cylinder 22 can be automatically adjusted by detecting the current change of the reducer 72. The sudden change of the running current and the actual rotation speed of the auxiliary wheel body 83 can be used to comprehensively judge whether the auxiliary wheel body 83 is in a slipping or overloaded state. The thrust is increased in time when slipping, and the thrust is reduced in time when overloaded. Through the combined adjustment of air pressure and frequency conversion, energy optimization is achieved while avoiding slipping or overloading of the auxiliary wheel body 83.

[0040] The above contents are merely examples and explanations of the structure of the utility model. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the utility model.
