Description

Technical Field

[0001] This utility model relates to the field of coal mine emulsion conveying technology, specifically to an adaptive and adjustable coal mine emulsion resistance-free transmission device. Background Technology

[0002] In fully mechanized coal mining faces, emulsion serves as the core medium for transmitting hydraulic power. The precise supply of its flow rate directly determines the coordination and response speed of equipment such as hydraulic supports and coal mining machines. For example, the lifting, pushing, and moving of hydraulic supports require emulsion flows of varying amounts. Lifting requires a large flow rate to quickly complete the support and ensure roof stability, while fine-tuning requires a small flow rate for precise control. Similarly, the lifting and traction speed adjustment of the coal mining machine's cutting section relies on the dynamic matching of emulsion flow rates. A mismatch between the flow supply and equipment demands can lead to anything from sluggish movements and increased energy consumption to serious safety hazards such as equipment jamming and support failure.

[0003] For example, Chinese utility model patent application number 201620610906.X discloses a mining emulsion distributor. By setting up a two-way diversion valve seat, a diversion pipe A, a one-way output pipe, a gate valve, and a flow regulating valve, it helps to achieve two-stage diversion output and flow regulation of the emulsion. The installation of a pump box and a one-way input pipe facilitates the installation of a pump-type power source and the input of the emulsion. It is simple in structure, easy to operate, and economical. However, this device still has certain shortcomings. Flow regulation is achieved by setting a flow regulating valve. The flow regulating valve is located between two pipes. When disassembling the flow regulating valve for maintenance, both pipes need to be disassembled, which is inconvenient for maintenance and replacement of the flow regulating valve.

[0004] Therefore, we propose an adaptive adjustment device for the resistanceless transmission of coal mine emulsion to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide an adaptive and adjustable coal mine emulsion resistance-free transmission device to solve the problem mentioned in the background art that the current market achieves flow regulation by setting a flow regulating valve, which is located between two pipes. When disassembling the flow regulating valve for maintenance, it is necessary to disassemble both pipes, which is inconvenient for maintenance and replacement of the flow regulating valve.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adaptive adjustment coal mine emulsion resistance-free transmission device, comprising a first conveying pipe, a second conveying pipe and an installation box, wherein the second conveying pipe is connected to the right side of the first conveying pipe, a circular block is installed inside the first conveying pipe and a conveying port is opened on the circular block, a connecting plate is installed on the right side of the second conveying pipe, and an installation box is provided on the right side of the second conveying pipe.

[0007] Preferably, the first and second conveying pipes are interconnected, the connecting plate is connected to the mounting box by fastening bolts, and the mounting box is provided with an inspection door.

[0008] With the above structural design, the second delivery pipe is connected to the mounting box via a connecting plate and fastening bolts to ensure a sealed emulsion delivery path; the inspection door on the mounting box facilitates the maintenance of internal components, allowing maintenance without disassembling the pipes, thus improving operational convenience. Even when disassembling the mounting box, it is not necessary to disassemble the first and second delivery pipes.

[0009] Preferably, the left end of the tapered column is located inside the second conveying pipe, and the center line of the tapered column coincides with the center line of the conveying port.

This ensures that the flow area of ​​the conveying port is accurately adjusted when the tapered column moves, stabilizes the emulsion flow rate, and avoids increased resistance due to deviation.

[0011] Preferably, the connecting disc has a sealing groove inside, and the sealing ring engages with the sealing groove.

[0012] With the above structural design, the sealing groove of the connecting plate engages with the sealing ring on the conical column, enhancing the sealing between the conical column and the connecting plate, preventing emulsion leakage, and ensuring conveying efficiency.

[0013] Preferably, a connecting block is installed on the tapered column, and a movable block is installed below the connecting block. A guide rod passes through the movable block, the guide rod is connected to the mounting plate, and the movable block is slidably connected to the guide rod.

[0014] With the above structural design, the conical column is connected to the movable block through the connecting block. The movable block slides along the guide rod on the mounting plate, which restricts the movement trajectory of the conical column, ensures stable flow regulation, and avoids regulation deviation caused by shaking.

[0015] Preferably, the threaded post extends through the mounting plate, and drive shafts are installed on both the left and right sides of the pinion. A rotary motor is installed on the right side of the mounting box, and the left side of the rotary motor is connected to the drive shaft through an output shaft. The pinion and the reduction gear mesh with each other.

[0016] With the above structural design, the threaded column passes through the mounting plate, and the rotary motor drives the pinion through the transmission shaft, which meshes with the reduction gear to transmit power, thereby driving the threaded hollow column to move in conjunction with the threaded column, so as to achieve precise movement and adjustment of the tapered column.

[0017] Preferably, the first conveying pipe is designed in two sections and is connected to the first conveying pipe by a flange. A filter screen is installed inside the first conveying pipe, and the filter screen is located near the flange.

[0018] With the above structural design, the first delivery pipe is a two-section design, connected by a flange. The first delivery pipe can be separated by removing the flange, making it easy to take out the filter screen near the flange for cleaning or replacement, thus ensuring the cleanliness of the emulsion.

The conical column and the center line of the conveying port coincide, and with the guiding effect of the movable block, additional resistance is avoided during adjustment, ensuring smooth delivery of emulsion and improving the coordination of hydraulic equipment movements. 2. Facilitates maintenance and repair, reducing operational difficulty. The mounting box is connected to the second delivery pipe via a connecting plate and fastening bolts. The inspection door on it allows direct maintenance of the internal adjustment components without disassembling the pipes. Even when disassembling the mounting box, it is not necessary to disassemble the first and second delivery pipes. Attached Figure Description

Example 2

[0025] Please see Figure 5 This utility model provides a technical solution: an adaptive adjustment coal mine emulsion resistance-free transmission device, including a flange 21 and a filter screen 22.

The pinion 18 meshes with the reduction gear 15, driving the threaded hollow column 14 to rotate. This causes the threaded column 16 at the left end to move axially along the mounting plate 13, thereby pushing the conical column 8 to move within the second conveying pipe 2. The conical column 8 slides along the guide rod 17 through the movable block 12 connected by the connecting block 11, ensuring a stable movement trajectory. The conical part at its left end coincides with the center line of the conveying port 4.
