Description

Technical Field

[0001] This utility model belongs to the field of coal transportation technology, and more specifically, it relates to a device for breaking up frozen coal on trains. Background Technology

[0002] In some areas during winter, due to low temperatures, coal freezing during train transport is a significant problem, becoming a major obstacle to the normal production and operation of coal-using units. The frozen coal layer on the car walls and unloading points can reach a thickness of about 30 centimeters, greatly increasing the difficulty of unloading and resulting in a significant reduction in unloading efficiency.

[0003] Currently, the unloading process uses a screw unloader to crush frozen coal from the top of the car body. However, this method has obvious limitations: the frozen coal at the unloading port cannot be crushed and removed. Even if the frozen coal at the top of the car body is crushed, the crushed coal has nowhere to be discharged due to the blockage at the unloading port, ultimately resulting in the frozen coal not being able to be unloaded smoothly. Utility Model Content

[0004] The purpose of this invention is to provide a device for breaking up frozen coal in train carriages, so as to solve the technical problem that coal is difficult to unload from carriages in winter.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a device for breaking up frozen coal on trains, comprising:

[0006] A lifting mechanism is arranged vertically and is used for fixed installation above the carriage; the free end of the lifting mechanism extends downward.

[0007] The drilling rig is fixedly connected at the upper end to the free end of the lifting mechanism, and has a drill bit at the lower end for working on frozen coal; the drilling rig moves up and down with the lifting mechanism to avoid the car body and drill through the frozen coal;

[0008] A drive mechanism, connected to the lifting mechanism, is used to drive the free end of the lifting mechanism to rise or fall.

[0009] In one possible implementation, the lifting mechanism includes a multi-stage hydraulic telescopic boom and an oil pipe connection port mounted on the multi-stage hydraulic telescopic boom; the drive mechanism is connected to the oil pipe connection port.

[0010] In one possible implementation, the drive mechanism includes an oil tank, a motor, a pump, and a pipeline for connecting the oil tank and the pump, and the pump to the oil pipe connection port.

[0011] In one possible implementation, the oil tank is provided with an integrated block and a valve installed on the integrated block, the pump is connected to the integrated block via a pipeline, and the integrated block is connected to the oil pipe connection port via a pipeline.

[0012] In one possible implementation, the valve is a sensitive proportional multi-way directional valve.

[0013] In one possible implementation, each of the multiple telescopic boom ends on the multi-stage hydraulic telescopic boom is provided with a coal retaining plate.

[0014] In one possible implementation, an observation hole is provided on the outermost telescopic arm of the multi-stage hydraulic telescopic arm.

[0015] In one possible implementation, the free end of the lifting mechanism is provided with a flange for connection to the drilling rig.

[0016] In one possible implementation, the train frozen coal breaking device further includes a beam frame located above the carriage, and the lifting mechanism is provided with a mounting seat connected to the beam frame.

[0017] In one possible implementation, the beam frame is provided with pulleys for linear movement.

[0018] The beneficial effects of the frozen coal breaking device for trains provided by this utility model are as follows: Compared with the prior art, the frozen coal breaking device for trains of this utility model consists of a vertically arranged lifting mechanism fixed above the carriage, a drilling rig connected to the free end of the lifting mechanism, and a drive mechanism that drives the lifting mechanism. The drill bit at the lower end of the drilling rig can directly act on the frozen coal, and the lifting mechanism can drive the drilling rig to move up and down, thus avoiding the carriage and drilling through the frozen coal, accurately aiming at the frozen coal at the unloading port. During operation, after the train carrying coal arrives at the unloading point, the drive mechanism first drives the free end of the lifting mechanism to move downward. At this time, the drilling rig connected to the free end moves down accordingly. Since the lifting mechanism can accurately control the stroke, the drilling rig can smoothly avoid the carriage body and directly aim at the unloading port and the surrounding frozen coal area. Then the drilling rig starts, and under the continuous downward pressure of the lifting mechanism, the drill bit at the lower end gradually drills through the frozen coal layer until the unloading channel is completely opened, thereby allowing the coal to be unloaded from the unloading hole of the carriage. After the frozen coal is unloaded, the drive mechanism then raises the free end of the lifting mechanism, allowing the car to move to the next working area. This method overcomes the limitation of existing screw unloaders in handling frozen coal at the unloading port. The lifting mechanism enables flexible raising and lowering of the drilling rig, ensuring precise action on the frozen coal during breaking up and avoiding the car when not in operation. The drilling rig accurately drills through the unloading port and surrounding frozen coal, providing a discharge channel for the coal broken at the top, allowing for smooth discharge from the car.

[0031] Please see Figures 1 to 5 The present invention provides a frozen coal breaking device for trains. The frozen coal breaking device for trains includes a lifting mechanism 10, a drilling rig 20, and a drive mechanism 30. The lifting mechanism 10 is vertically arranged and is fixedly installed above the carriage 50. The free end of the lifting mechanism 10 extends downward. The upper end of the drilling rig 20 is fixedly connected to the free end of the lifting mechanism 10, and the lower end has a drill bit for acting on the frozen coal. The drilling rig 20 moves up and down with the lifting mechanism 10 to avoid the carriage 50 and drill through the frozen coal. The drive mechanism 30 is connected to the lifting mechanism 10 and is used to drive the free end of the lifting mechanism 10 to rise or fall.

[0032] Compared with the prior art, the frozen coal breaking device for trains provided by this utility model consists of a lifting mechanism 10 arranged vertically and fixed above the carriage 50, a drilling rig 20 connected to the free end of the lifting mechanism 10, and a drive mechanism 30 that drives the lifting mechanism 10 to run. The drill bit at the lower end of the drilling rig 20 can directly act on the frozen coal, and the lifting mechanism 10 can drive the drilling rig 20 to move up and down, so as to avoid the carriage 50 and drill through the frozen coal, accurately aiming at the frozen coal at the unloading port. During operation, after the coal train arrives at the unloading point, the drive mechanism 30 first drives the free end of the lifting mechanism 10 downwards. At this time, the drilling rig 20 connected to the free end moves downwards accordingly. Since the lifting mechanism 10 can precisely control its stroke, the drilling rig 20 can smoothly avoid the car body 50 and directly target the unloading port and the surrounding frozen coal area. Then, the drilling rig 20 starts, and under the continuous downward pressure of the lifting mechanism 10, the drill bit at the lower end gradually drills through the frozen coal layer until the unloading channel is completely opened, allowing the coal to be unloaded from the unloading hole of the car body 50. After the frozen coal is unloaded, the drive mechanism 30 then drives the free end of the lifting mechanism 10 to rise, allowing the car body 50 to move to the next working area. In this way, the limitation of existing spiral unloaders in handling frozen coal at the unloading port is solved. With the help of the lifting mechanism 10, the drilling rig 20 can be lifted and lowered flexibly. This ensures that it can accurately act on the frozen coal during the breaking process, and can also avoid the car body 50 when not in operation. The drilling rig 20 accurately drills through the unloading port and the surrounding frozen coal, providing a discharge channel for the coal after the top is broken, so that the coal in the car body 50 can be discharged smoothly.

[0033] Please see Figure 1 and Figure 2 , Figure 4 and Figure 5 As a specific embodiment of the frozen coal breaking device for trains provided by this utility model, the lifting mechanism 10 includes a multi-stage hydraulic telescopic arm 11 and an oil pipe connection port installed on the multi-stage hydraulic telescopic arm 11; the drive mechanism 30 is connected to the oil pipe connection port; the lifting mechanism 10 uses a multi-stage hydraulic telescopic arm 11 in conjunction with the oil pipe connection port, and the drive mechanism 30 drives its operation through the oil pipe connection port. Relying on the rigidity and stability of hydraulic transmission, the multi-stage structure can achieve long-stroke extension and retraction, accurately control the lifting height of the drilling rig 20, and adapt to the breaking requirements of different carriages 50 and 30 cm thick frozen coal. The hydraulic drive output force is large, which can drive the drilling rig 20 to powerfully drill through the frozen coal, and the extension stroke is flexible, which can accurately avoid the carriage 50 and position the frozen coal at the unloading port.

[0034] Please see Figures 1 to 3As a specific embodiment of the train frozen coal breaking device provided by this utility model, the drive mechanism 30 includes an oil tank 31, a motor 32, a pump 33, and a pipeline 34 for connecting the oil tank 31 and the pump 33, and the connection port of the pump 33 to the oil pipe, forming a complete hydraulic power supply system. Adapting to the power requirements of the hydraulic telescopic boom, the various components work together to achieve the storage, pressurization, and transmission of hydraulic oil, providing a stable power source for lifting and lowering operations. The motor 32 drives the pump 33 with high pressurization efficiency, providing strong and controllable hydraulic power output, and can precisely adjust the lifting speed and force of the telescopic boom, adapting to the breaking operations of frozen coal of different thicknesses.

[0035] Please see Figure 3 As a specific embodiment of the frozen coal breaking device for trains provided by this utility model, the oil tank 31 is equipped with an integrated block 35 and a valve 36 installed on the integrated block 35. The pump 33 is connected to the integrated block 35 through a pipeline 34, and the integrated block 35 is connected to the oil pipe connection port through a pipeline 34. The integrated block 35 and valve 36 are installed on the oil tank 31, and the pump 33 is connected to the integrated block 35, and the integrated block 35 is connected to the oil pipe connection port through the pipeline 34, forming a centralized hydraulic control node. The hydraulic oil circuit is integrated based on the integrated block 35, and the hydraulic oil output by the pump 33 is distributed to the hydraulic telescopic arm through the integrated block 35. The valve 36 can directly regulate the oil circuit opening and closing and the flow rate. The integrated design simplifies the layout of the pipeline 34, reduces the risk of leakage, and the precise control of the valve 36 can realize the fine adjustment of the telescopic arm's lifting speed and force.

[0036] Preferably, in one specific embodiment of the frozen coal breaking device for trains provided by this utility model, valve 36 is a sensitive proportional multi-way directional valve. As a control component on the integrated block 35 of the oil tank 31, the sensitive proportional multi-way directional valve has both sensitive adjustment and multi-way control functions. It can accurately respond to pressure changes in the hydraulic system and simultaneously achieve multi-channel control of hydraulic oil flow and direction, adapting to the oil circuit layout connecting the pump 33 and the hydraulic telescopic arm of the integrated block 35. The adjustment accuracy of the sensitive proportional multi-way directional valve far exceeds that of the ordinary valve 36. It can finely adjust the hydraulic oil supply in real time according to the resistance changes encountered during the drilling of frozen coal, thereby accurately controlling the lifting speed of the drilling rig 20 and the drill bit pressure. Furthermore, the multi-way control function simplifies oil circuit switching operations and improves system response efficiency.

This can effectively block the coal slag and coal fragments generated when the drilling rig 20 breaks frozen coal, prevent them from entering the gaps or connecting parts of the telescopic arm, prevent the telescopic arm from being obstructed due to coal slag jamming, and at the same time reduce the impact and wear of coal slag on the arm body.

The ring structure and multi-bolt hole design of the flange 14 achieve a rigid connection between the lifting mechanism 10 and the drilling rig 20. The connection point precisely corresponds to the core stress area of ​​the free end, adapting to the longitudinal pressure transmission requirements of the drilling rig 20 during operation. A flange 14 is also provided at the upper end of the drilling rig 20 to significantly improve the connection strength and stability, preventing loosening of the connection and subsequent displacement of the drilling rig 20. Simultaneously, the flange 14 facilitates easy connection and disassembly, making it convenient for the inspection, replacement, and maintenance of the drilling rig 20.
