Description

Technical Field

[0001] The present invention relates to the technical field of underground monorail cranes, and more particularly to an underground monorail crane adopting self-cleaning auxiliary lubrication. Background Art

[0002] The monorail transportation equipment used in coal mines adopts a monorail suspension design, which can move along the tunnels or working faces of the mine to achieve rapid transportation of coal, materials and personnel;

[0003] Referring to the patent document with the authorization announcement number CN116969325B, in this patent, after the driving chamber is braked, the crane moves toward the driving chamber under the action of inertia, and the movement of the crane pushes the piston rod on the left side of the first connecting rod into the second connecting rod, and the gas inside the second connecting rod is pushed into the inside of the driven wheel and pressurizes the rubber sleeve wrapped outside the driven wheel. Under the action of air pressure, the rubber sleeve expands, the diameter of the driven wheel increases, and the movement of the driven wheel inside the I-beam rail is blocked. The driven wheel is emergency braked and the crane stops moving. With respect to the above-mentioned related technologies, during emergency braking, in order to stop the inertial movement of the crane, the rubber sleeve is subject to greater friction and is prone to damage, which will affect the braking effect of the crane and pose a greater safety hazard.

[0004] Another example is the patent document with publication number CN118004890B. In the device, the friction block can move upward to rub against the rail during braking, thereby blocking the inertial movement of the hanger. The braking effect is stable, reducing the risk of collision of the crane due to inertial movement during emergency braking.

[0005] However, in the above patent documents, since the underground environment is usually harsh, there are a lot of water stains, coal ash, lumps, etc., which will cause these substances to easily adhere to the surface of the track to form impurities and particles, thereby affecting the movement of the driving tooling. It is impossible to clean the impurities and particles on the track in time when the underground monorail crane is working, and lubricate the track after cleaning to avoid wear of the track and wheels and improve the operation efficiency of rail transportation;

[0006] In view of the above technical defects, a solution is now provided. Summary of the invention

[0014] Furthermore, the lubricating member includes a reciprocating screw rotatably arranged inside the lubrication box, and an end of the reciprocating screw extends to the outside of the lubrication box and is fixedly connected to a connecting shaft.

[0015] Furthermore, a refueling box is arranged on the outer side of the reciprocating screw rod, and the refueling box is fixedly connected to the inner wall of the lubrication box.

[0016] Furthermore, the outer side of the reciprocating screw is threadedly connected to a piston plate, and the piston plate is slidably matched with the inner wall of the fuel tank, and an oil inlet pipe is vertically inserted into the bottom of the fuel tank.

[0017] Furthermore, an output pipe is vertically inserted into the side wall of the fuel tank, and one-way valves are provided on the outer walls of the oil inlet pipe and the output pipe.

[0018] Furthermore, two refueling pipes are arranged on the outer wall of the output pipe, and the output ends of the refueling pipes are arranged toward the inner wall of the track.

[0019] Among them, the cleaning and lubrication method of the underground monorail crane is:

[0020] When the driving tool is driven, the matching roller rotates, so that the driving shaft drives the connecting shaft 1 and the connecting shaft 2 to rotate;

[0021] Lubrication method: When the connecting shaft rotates, the piston plate moves back and forth, and the lubricating oil inside the lubrication box is discharged to the top of the track through the output pipe and two filling pipes to lubricate the inner wall of the track;

[0036] Embodiment 1: Figure 1-7 As shown, the underground monorail crane adopting self-cleaning auxiliary lubrication proposed in this embodiment includes a track 1, on which a driving chamber 2, a driving tool 3 and a plurality of mounting frames 6 for hoisting materials are arranged, the mounting frames 6 and the driving chamber 2 can move under the drive of the driving tool 3, the tops of the mounting frames 6 and the driving chamber 2 are both provided with connecting tubes 4, two adjacent connecting tubes 4 are fixedly connected by connecting columns 5, and the outer side of the connecting columns 5 is provided with a cleaning and lubricating component 7 for cleaning and lubricating the track 1;

[0037] It should be noted that the driving tool 3 is a functional device in the prior art that has the function of driving multiple mounting racks 6 to move. It only needs to have the driving function for the above-mentioned mounting racks 6, and no further elaboration is given here.

[0038] like Figure 1-3 As shown, the cleaning and lubricating assembly 7 includes a connecting block 71 fixedly connected to the connecting column 5, a lubrication box 72 is arranged on the top of the connecting block 71, and a lubrication member 76 for lubricating the inner wall of the track 1 is arranged inside the lubrication box 72, and a driving shaft 74 is rotatably arranged at the bottom of the connecting column 5 through a connecting plate, and a matching roller 73 is fixedly arranged in the middle of the driving shaft 74, and the matching roller 73 is drivingly matched with the top wall of the track 1;

[0039] It should be noted that the outer wall of the mating roller 73 is provided with friction patterns or rubber pads, both of which play a role in increasing the friction between the mating roller 73 and the top wall of the track 1, thereby ensuring that the mating roller 73 rotates when in contact with the top wall of the track 1, thereby realizing the driving of the driving shaft 74;

[0040] like Figure 1-3 As shown, a cleaning member 75 for cleaning the inner wall of the track 1 is arranged on the outer side of the connecting plate, and the cleaning member 75 includes two sets of mounting plates 751, and the two sets of mounting plates 751 are symmetrically mounted on both sides of the connecting block 71, and a second transmission member 755 is arranged on both sides of the driving shaft 74, and a second connecting shaft 756 is arranged at the bottom of the second transmission member 755, and a cleaning roller 754 is arranged on the outer wall of the second connecting shaft 756, and the cleaning roller 754 and the inner wall of the track 1 are in contact with each other;

[0041] like Figure 1-3 As shown, a transmission member 753 is provided on both sides of the driving shaft 74, and a connecting shaft 752 is provided on the top of the transmission member 753;

[0042] It should be supplemented here that: the transmission member 1 753 includes two transmission wheels 1, one transmission wheel 1 is fixedly connected to the connecting shaft 1 752, and the other transmission wheel 1 is fixedly connected to the driving shaft 74, and the two transmission wheels 1 are matched through a transmission belt 1; that is, when the driving shaft 74 rotates, it drives one of the transmission wheels 1 to rotate, and through the transmission of the transmission belt 1, it drives the other transmission wheel 1 to rotate, and then realizes the rotation of the connecting shaft 1 752, so that the reciprocating screw rod 762 rotates;

[0043] The transmission member 2 755 includes two transmission wheels 2, one of which is fixedly connected to the connecting shaft 2 756, and the other is connected to the driving shaft 74, and the two transmission wheels 2 are matched with each other through the transmission belt 2; that is, when the driving shaft 74 rotates, it drives one of the transmission wheels 2 to rotate, and through the transmission of the conveyor belt 2, it drives the other transmission wheel 2 to rotate, thereby realizing the rotation of the connecting shaft 2 756, so that the cleaning roller 754 rotates to clean the inner wall of the track 1;

[0044] When the driving chamber 2 is driven, the multiple connecting columns and the connecting cylinder 4 move synchronously. At the same time, the matching roller 73 cooperates with the top transmission of the track 1, thereby driving the rotation of the driving shaft 74. When the second connecting shaft 756 rotates, it drives the two cleaning rollers 754 to rotate synchronously, thereby realizing the synchronous cleaning of both sides of the track 1, preventing impurities such as hard particles above the track 1 from being embedded between the track 1 and the wheel, aggravating wear and causing damage to the surface of the track 1. At the same time, impurities such as dirt and dust on the track 1 will interfere with the uniform distribution of the lubricant and affect the lubrication effect.

[0045] Embodiment 2: Figure 1-3 As shown in 5-6, the underground monorail crane adopting self-cleaning auxiliary lubrication proposed in this embodiment is improved on the basis of embodiment 1, and the lubricating member 76 includes a reciprocating screw 762 rotatably arranged inside the lubrication box 72, and the end of the reciprocating screw 762 extends to the outside of the lubrication box 72 and is fixedly connected to the connecting shaft 1 752, and a refueling box 761 is arranged on the outside of the reciprocating screw 762, and the refueling box 761 is fixedly connected to the inner wall of the lubrication box 72;

[0046] like Figure 1-3 As shown in 5-6, the outer side of the reciprocating screw rod 762 is threadedly connected with a piston plate 766, and the piston plate 766 is slidably matched with the inner wall of the refueling box 761, an oil inlet pipe 764 is vertically inserted at the bottom of the refueling box 761, and an output pipe 763 is vertically inserted on the side wall of the refueling box 761, and a one-way valve is provided on the outer wall of the oil inlet pipe 764 and the output pipe 763, and two refueling pipes 765 are provided on the outer wall of the output pipe 763, and the output end of the refueling pipe 765 is arranged toward the inner wall of the track 1;

[0047] The transmission member 1 753 and the transmission member 2 755 on both sides of the drive shaft 74 are synchronously driven to respectively realize the transmission of the connecting shaft 1 752 and the connecting shaft 2 756. When the connecting shaft 1 752 rotates, the reciprocating screw rod 762 is synchronously driven, thereby driving the reciprocating movement of the piston plate 766, and the lubricating oil inside the lubrication box 72 is discharged to the top of the track 1 through the output pipe 763 and the two filling pipes 765, so as to lubricate the inner wall of the track 1, thereby reducing the friction between the driving tool 3 and the track 1;

[0048] It should be supplemented here that: the reciprocating screw 762 is driven to rotate by the connecting shaft 1 752. When the reciprocating screw 762 rotates, the piston plate 766 reciprocates inside the refueling box 761. When the piston plate 766 is away from the oil inlet pipe 764, the lubricating oil enters the inside of the refueling box 761 through the oil inlet pipe 764. When the piston plate 766 is close to the oil inlet pipe 764, the lubricating oil is discharged through the output pipe 763 and then enters the inside of the two refueling pipes 765. The lubricating oil discharged through the refueling pipes 765 lubricates the inner wall of the track 1, reducing the friction, thereby reducing the wear of the track 1 and the wheels, and improving the operation efficiency of the track 1 traffic.

[0049] In the present invention, it can be seen from the combination of the first embodiment and the second embodiment that the underground monorail crane has the functions of lubrication and cleaning, which not only ensures the lubrication of the track 1 to reduce the friction between the driving tool 3 and the track 1, but also realizes the synchronous cleaning of the track 1 to prevent impurities and dirt from having a negative impact on the lubrication effect and the surface of the track 1, and cooperates with each other to jointly improve the operation efficiency of the track 1 traffic;

[0050] Working principle: Driving method: The driving tool 3 is controlled by the driving room 2 to work, and the driving tool 3 drives multiple mounting frames 6 to slide above the track 1, thereby realizing the transfer of materials;

[0051] Lubrication method: When the driving chamber 2 is driven, the multiple connecting columns and the connecting cylinder 4 move synchronously. At the same time, the matching roller 73 cooperates with the top transmission of the track 1, thereby driving the rotation of the driving shaft 74. The transmission member 1 753 and the transmission member 2 755 on both sides of the driving shaft 74 are synchronously driven to realize the transmission of the connecting shaft 1 752 and the connecting shaft 2 756 respectively.

[0052] When the connecting shaft 1 752 rotates, the reciprocating screw rod 762 is driven synchronously, thereby driving the piston plate 766 to reciprocate, and the lubricating oil inside the lubrication box 72 is discharged to the top of the track 1 through the output pipe 763 and the two filling pipes 765, so as to lubricate the inner wall of the track 1, thereby reducing the friction between the driving tool 3 and the track 1;

[0053] Cleaning method: When the connecting shaft 2 756 rotates, it drives the two cleaning rollers 754 to rotate synchronously, thereby achieving synchronous cleaning of both sides of the track 1, preventing impurities such as hard particles above the track 1 from being embedded between the track 1 and the wheel, aggravating wear and causing damage to the surface of the track 1. At the same time, impurities such as dirt and dust on the track 1 will interfere with the uniform distribution of the lubricant and affect the lubrication effect.

[0054] Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and describes these embodiments in detail in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well.
