[0001] The utility model relates to the technical field of single hydraulic props, in particular to a long-distance liquid supply device for a single hydraulic prop. Background Art

[0002] The single hydraulic prop is a relatively traditional and reliable support equipment, which is often used in coal mining. The single hydraulic prop and injection gun commonly used in coal mines are directly connected and used in conjunction.

[0003] When in use, connect and fix the injection gun to the three-purpose liquid inlet end of the single hydraulic column, press the handle of the injection gun to supply liquid, so that the single hydraulic support is extended, and directly connect the injection gun to the three-purpose valve of the single hydraulic support to complete the connection and liquid supply operation.

[0004] Currently, most of the connections for liquid supply devices on the market are made by two to three people. Each person stands at a corresponding position and supplies liquid to the three-way valve and injection gun at close range. However, during use, the single hydraulic support is easily slipped and bounced under stress, which may cause injury accidents. In addition, when the liquid supply pipeline is damaged, it needs to be replaced as a whole, which increases costs. Utility Model Content

[0005] The purpose of the utility model is to solve the problems in the prior art that a single hydraulic support easily slips and bounces up when subjected to force, causing injuries, and is difficult to replace the liquid supply pipeline, thereby increasing costs. A single hydraulic support long-distance liquid supply device is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A single hydraulic prop remote fluid supply device, comprising a high-pressure hose for mining, characterized in that both ends of the high-pressure hose for mining are U-shaped pin-type quick connectors, one end of the U-shaped pin-type quick connector is equipped with a connector connected to a three-way valve for the single hydraulic prop, and the other end of the U-shaped pin-type quick connector is equipped with a connector connected to an outlet of a liquid injection gun for the single hydraulic prop, an anti-slip ring is installed on the U-shaped pin-type quick connector, and a lock buckle is slidably sleeved on the outer portion of the liquid inlet of the anti-slip ring and the connector connected to the three-way valve for the single hydraulic prop;

[0008] Also includes:

[0009] A disassembly part, the disassembly part is used for assembling and disassembling the U-shaped pin type quick connector;

[0010] A locking piece is used to lock the U-shaped pin type quick connector.

[0011] Preferably, the disassembly component includes:

[0012] Insert joints, the insert joints are welded on opposite sides of the mining high-pressure hose, and the insert joints are plugged into the U-shaped pin-type quick connector;

[0013] The insertion groove is provided in the U-shaped pin type quick connector, and the insertion groove matches the shape of the insertion connector.

[0014] Preferably, the locking member comprises:

[0015] A pin hole is provided on the U-shaped pin-type quick connector, and two pin holes are symmetrically provided;

[0016] A U-shaped pin is inserted into the pin hole.

[0017] Preferably, the connector connected to the outlet of the single hydraulic prop injection gun is of the same shape as the connector on the hydraulic prop three-way valve, and the connector connected to the single hydraulic prop three-way valve is of the same shape as the connector on the injection gun.

[0018] Preferably, an annular notch is provided on the joint connected to the outlet of the single hydraulic prop injection gun.

[0019] Preferably, the top surface of the lock buckle is provided with a semi-circular upward protrusion, and the inner wall of the semi-circular upward protrusion is provided with a semi-circular outward protrusion, the semi-circular outward protrusion of the lock buckle is clamped with the annular recess, the interior of the lock buckle is annularly hollow, and the lock buckle is placed between the anti-slip ring and the joint connected to the three-way valve of the single hydraulic support to slide.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1. The utility model connects the connectors at both ends of the device to the liquid outlet of the injection gun and the liquid inlet of the three-way valve of the single hydraulic support, respectively. Then, a sliding push-pull lock is slid and snapped into the annular recess to secure the two. This allows for a secure installation and facilitates use, allowing the device to be quickly connected, thereby achieving quick connection and improving installation efficiency. At the same time, after installation, since the high-pressure hose used in mining is relatively long, the device allows personnel to supply liquid to the single hydraulic support while standing in a safe area, thus preventing accidents in which the single hydraulic support bounces under force and injures people.

[0022] 2. The utility model adopts the connection mode of inserting joint and inserting groove after the high-pressure hose for mining is damaged, so the high-pressure hose for mining can be easily disassembled and replaced, and the cooperation of the pin hole and the U-shaped pin realizes the firm connection between the U-shaped pin type quick connector and the high-pressure hose for mining. In addition, since the high-pressure hose with the U-shaped pin type quick connector is widely available, the high-pressure hose can be removed through the quick connector after being damaged and replaced separately, avoiding the need to replace the joint and the like as a whole after being damaged, thereby reducing costs.

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Reference Figure 1-Figure 5 A remote fluid supply device for a single hydraulic prop includes a high-pressure mining hose 1, with U-shaped pin-type quick connectors 2 at both ends. A connector 3 connected to a three-way valve for the single hydraulic prop is installed on the end side of one side of the U-shaped pin-type quick connector 2, and a connector 4 connected to the outlet of a liquid injection gun for the single hydraulic prop is installed on the end side of the other side of the U-shaped pin-type quick connector 2. An anti-slip ring 5 is installed on the U-shaped pin-type quick connector 2, and a lock buckle 6 is slidably sleeved on the anti-slip ring 5 and the liquid inlet of the connector 3 connected to the three-way valve for the single hydraulic prop;

[0032] A single hydraulic prop remote fluid supply device further includes a disassembly part and a locking part. The disassembly part is used to install and remove the U-shaped pin type quick connector 2, and the locking part is used to lock the U-shaped pin type quick connector 2. This allows the mining high-pressure hose 1 to be firmly connected to the U-shaped pin type quick connector 2.

[0033] The disassembly parts include a through-joint 101 and a through-groove 21. The through-joint 101 is welded to opposite sides of the mining high-pressure hose 1. The through-groove 21 is provided in the U-shaped pin-type quick connector 2, and the shape of the through-groove 21 matches that of the through-joint 101. The through-joint 101 matches the through-groove 21 in the U-shaped pin-type quick connector 2, thereby achieving a tight and stable connection. The through-joint 101 is fixed to the mining high-pressure hose 1 by welding, ensuring the firmness and sealing of the joint.

[0034] The locking member includes a pin hole 22 and a U-shaped pin 23. The pin holes 22 are symmetrically arranged on the U-shaped pin quick connector 2, and the U-shaped pin 23 is inserted into the pin holes 22. The U-shaped structure provides additional locking force. When the U-shaped pin 23 is inserted into the pin hole 22, its two ends will be respectively locked on both sides of the pin hole 22, thereby effectively preventing the U-shaped pin quick connector 2 from moving relative to other components or falling off.

[0035] The connector 4 connected to the outlet of the hydraulic prop injection gun is of the same shape as the connector on the hydraulic prop three-way valve, and the connector 3 connected to the hydraulic prop three-way valve is of the same shape as the connector on the injection gun. The same shape of the connectors ensures that they fit tightly when connected, preventing leakage and thus ensuring the normal operation of the hydraulic prop.

[0036] The connector 4 connected to the outlet of the single hydraulic prop injection gun is provided with an annular notch 41. The annular notch 41 provides a snap-in point for the lock buckle 6, ensuring that the lock buckle 6 can be firmly fixed on the connector.

[0037] The top surface of the lock buckle 6 is provided with a semi-circular upward protrusion, and the inner wall of the semi-circular upward protrusion is provided with a semi-circular outward protrusion. The semi-circular outward protrusion of the lock buckle 6 is engaged with the annular recess 41. The interior of the lock buckle 6 is annularly hollow. The lock buckle 6 is placed between the anti-slip ring 5 and the connector 3 connected to the single hydraulic prop three-way valve and slides. The semi-circular upward protrusion design on the top surface of the lock buckle 6 can cooperate with the annular recess 41 on the connector 4 connected to the outlet of the single hydraulic prop injection gun to achieve preliminary locking. The semi-circular outward protrusion on the inner wall of the lock buckle 6 further enhances the clamping force between the lock buckle 6 and the annular recess 41, ensuring a more stable connection. The interior of the lock buckle 6 is annularly hollow, which not only reduces the weight of the lock buckle 6, but also makes it easier to slide on the U-shaped pin type quick connector 2, facilitating installation and disassembly.

[0038] The functional principle of this utility model can be explained through the following operation modes:

[0039] When using the device, first push the lock buckle 6 to slide along the anti-slip ring 5, and the end side of the lock buckle 6 protrudes away from the joint 3 connected to the single hydraulic support three-way valve to facilitate the protruding installation of its joint. Then, align the joint 3 connected to the single hydraulic support three-way valve with the three-way valve and embed it into the installation, and embed the joint 4 connected to the outlet of the single hydraulic support injection gun into the corresponding connection joint on the injection gun (the joint 3 connected to the single hydraulic support three-way valve has the same style as the joint of the injection gun, and the joint connected to the injection gun has the same style as the joint of the three-way valve), so that the two ends are preliminarily connected and installed with the injection gun and the three-way valve respectively. After installation, slide and push the lock buckle 6, and the lock buckle 6 slides down and is clamped in the annular recess 41, so that the device is stably connected for easy use. The long-term use of the mining high-pressure hose 1 is prone to damage. When replacing it, pull out the U-shaped pin 23 and slide it outward to the pin hole 22. The U-shaped pin 23 is separated from the pin hole 22 and contacts the limit, so that the U-shaped pin quick connector 2 is separated from the mining high-pressure hose 1, and the new mining high-pressure hose 1 is inserted into the U-shaped pin quick connector 2, and the insertion joint 101 on its end side is embedded in the insertion groove 21 in the U-shaped pin quick connector 2, and the U-shaped pin 23 is inserted into the pin hole 22 until its two ends are completely stuck on both sides of the pin hole 22 to form a lock, so that the two can be quickly replaced and continued to be used, so that the mining high-pressure hose 1 can be replaced alone after it is damaged, avoiding the need to replace the U-shaped pin quick connector 2, the joint, etc. as a whole when damaged, thereby reducing costs.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
