Description

Technical Field

[0001] This utility model relates to the field of hydraulic support locking technology, and specifically to a hydraulic support locking mechanism. Background Technology

[0002] In the coal mining industry, support safety and efficiency are paramount. Early coal mines primarily used traditional support methods such as timber supports and metal friction props. These methods offered low support strength and poor stability, making them unsuitable for complex geological conditions and the demands of high-yield, high-efficiency mining. In the mid-20th century, hydraulic supports emerged, powered by high-pressure fluid, automatically adjusting their support status based on roof pressure, significantly improving support reliability and operational safety. With technological advancements, hydraulic supports have continuously evolved, from simple structures to those with electro-hydraulic control and intelligent monitoring functions. They can work in conjunction with coal mining machines and scraper conveyors, becoming key equipment for achieving automated and intelligent coal mining.

[0003] Authorization Announcement No. CN 222596108 U discloses a hydraulic support limiting device for mining equipment, comprising a control console, a limiting box fixedly connected to the control console, a plurality of first and second sliding grooves formed on the limiting box, a plurality of control rods penetrating the first sliding grooves on the control console, and a plurality of locking grooves formed on the inner side of the limiting box on one side of the second sliding groove. The advantages of this invention are: by setting up a locking box, springs, and other structures, when the control rod needs to be adjusted, pressing down on the pressure rod pushes the mounting block to compress the spring, and the mounting block drives the locking block to move downwards and disengage from the locking groove, thus unlocking the control rod. After the control rod is operated, releasing the pressure rod causes the spring to push the mounting block upwards, and the mounting block drives the locking block into the locking groove, thus locking the control rod. No separate locking operation is required after adjustment, making it more convenient to use and avoiding problems caused by forgetting to lock or neglecting to lock for convenience that could affect the operation of the hydraulic support.

[0004] While the above equipment can prevent the hydraulic support from being locked due to forgetting to lock, it requires the simultaneous operation of the control lever and the pressure lever. This increases the complexity and difficulty of the operation, reduces work efficiency, and makes it easy to become flustered when operating two components at the same time, leading to operational errors. For example, if the pressure lever is not pressed correctly and the locking block is not fully disengaged from the locking groove, forcibly adjusting the control lever may damage the control lever, locking block, or locking groove. Utility Model Content

[0005] In view of this, the present invention provides a hydraulic support locking mechanism, which allows the control lever to be unlocked without the need for separate operation of the pressure lever.

[0006] To solve the above-mentioned technical problems, this utility model provides a hydraulic support locking mechanism, including a control console mounted on a hydraulic support. A self-locking box is fixedly mounted on the control console, and the self-locking box has several sliding grooves. A self-locking assembly is installed inside the self-locking box, and the self-locking assembly includes multiple sets of arc-shaped adjusting blocks installed inside the self-locking box. Each set of arc-shaped adjusting blocks is located at the bottom of a sliding groove, and each set of arc-shaped adjusting blocks has several adjusting slots. Several sleeves are hinged to the control console via hinge seats, and a control rod is slidably mounted inside each sleeve. Two limiting posts are provided on the outer arc surface of the control rod, and the two limiting posts are located within the adjusting slots on the arc-shaped adjusting blocks. That is, firstly, the personnel... When operating the hydraulic support, pressure is applied to the operating lever, causing it to enter the sleeve. Simultaneously, the two limit posts on the operating lever disengage from the adjustment grooves on the arc-shaped adjusting block. The operator can then rotate the operating lever to control the hydraulic support. When the hydraulic support is in the desired position, the operating lever, under the action of the self-locking component, moves upwards inside the sleeve, causing the two limit posts on the operating lever to re-enter the adjustment grooves on the arc-shaped adjusting block. This completes the self-locking of the hydraulic support, allowing the operator to unlock the control lever without needing to operate the pressure lever separately, thus improving work efficiency.

[0007] The self-locking assembly also includes guide grooves formed on each set of arc-shaped adjustment blocks, and the guide grooves are connected to the ends of several adjustment grooves; thus facilitating the sliding of the two limiting posts within the guide grooves and several adjustment grooves.

[0008] The self-locking assembly also includes a pressing block located at the end of the control lever, inside the sleeve; that is, the pressing block can prevent the control lever from disengaging from the sleeve, indirectly playing a limiting role.

[0009] The self-locking assembly also includes a spring disposed inside the sleeve, with the two ends of the spring located at the bottom of the sleeve and the bottom of the pressing block, respectively; that is, the spring has a contraction function, thereby allowing the pressing block to move inside the sleeve.

[0010] The self-locking box is equipped with several guide marks, which are located at both ends of the slide; this makes it easy to operate the lever according to the guide marks.

[0011] A control ball is installed at the top of the control lever, which improves the comfort of the operator.

[0012] The top surface of the limit box is curved, which makes it easier for the control rod to slide along the curved trajectory.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. Through the setting of limit post, operating rod, sleeve, arc-shaped adjusting block and adjusting groove in the self-locking assembly, the operator only needs to apply axial pressure to the control rod, so that it slides down in the sleeve. The limit post on the outer arc surface of the control rod can simultaneously disengage from the adjusting groove of the arc-shaped adjusting block in the self-locking box, releasing the self-locking state. The control rod can rotate freely around the hinge seat, which is convenient for adjusting the position of the hydraulic support. After the pressure is stopped, the control rod moves up and resets in the sleeve, and the limit post re-locks into the corresponding adjusting groove to achieve automatic locking.

[0014] 2. Several guide marks are set on the self-locking box. The guide marks are located at both ends of the slide, which makes it easy to control the hydraulic support according to the angle and facilitates the subsequent adjustment of the hydraulic support to different postures.

Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0017] like Figure 1-4As shown: This embodiment provides a hydraulic support locking mechanism, including a control console 100 mounted on the hydraulic support. The control console 100 is used to control the raising and lowering of the hydraulic support. A self-locking box 101 is fixedly mounted on the control console 100, and the control console 100 provides support for the self-locking box 101. The self-locking box 101 has several sliding grooves. A self-locking assembly 200 is provided inside the self-locking box 101. The self-locking assembly 200 includes multiple sets of arc-shaped adjusting blocks 202 disposed inside the self-locking box 101. The multiple sets of arc-shaped adjusting blocks 202 are fixedly mounted on the self-locking box 101 by welding, so that the self-locking box 101 provides support for each set of arc-shaped adjusting blocks 202. Each set of arc-shaped adjusting blocks 202 is located at the bottom of the sliding groove, and each set of arc-shaped adjusting blocks 202 has several... A control rod is slidably mounted within an adjustment groove 206. The control console 100 has several sleeves 203 hinged to it via a hinge seat 204. Two limiting posts 205 are mounted on the outer arc surface of the control rod, and are fixedly installed by welding. These limiting posts 205 are located within the adjustment groove 206 on the arc-shaped adjustment block 202. When a person presses the control rod, it enters the sleeve 203, causing the limiting posts 205 on the control rod to slide out of the adjustment groove 206 and re-enter it. This achieves a rapid self-locking function, allowing the person to unlock the control rod without needing to manually press the lever, thus improving the speed of self-locking and unlocking. When an operator applies axial pressure to the control rod, it slides downward within the sleeve 203. At this time, the two limiting posts 205 on the outer arc surface of the control rod simultaneously disengage from the adjusting groove 206 of the arc-shaped adjusting block 202 inside the self-locking box 101. After the limiting posts 205 disengage, the control rod can rotate freely around the hinge seat 204. The operator adjusts the hydraulic support to the target position by rotating the control rod. After stopping the pressure, the control rod moves upward and resets within the sleeve 203. During the upward movement of the control rod, the limiting posts 205 re-engage into the adjusting groove 206 at the corresponding position of the arc-shaped adjusting block 202. The mechanical engagement of the groove and the post fixes the angle of the control rod, indirectly locking the current posture of the hydraulic support. This enables one-button operation and automatic locking, significantly improving work efficiency and safety.

[0018] Self-locking component 200 Figure 2 As shown, The self-locking assembly 200 also includes a guide groove 207 formed on each set of arc-shaped adjustment blocks 202. The guide groove 207 is connected to the ends of several adjustment grooves 206, so that the limiting post 205 is guided from the adjustment groove 206 to the guide groove 207, and can then slide in the guide groove 207 to re-enter another adjustment groove 206, thereby facilitating the adjustment of the angle of the control rod. The self-locking assembly 200 also includes a pressing block 208 disposed on the end of the control lever. The pressing block 208 is located inside the sleeve 203, thereby preventing the control lever from disengaging from the sleeve 203 and thus playing a limiting role. The self-locking assembly 200 also includes a spring 209 disposed inside the sleeve 203, with the two ends of the spring 209 located at the bottom of the sleeve 203 and the bottom of the pressing block 208, respectively. The self-locking box 101 is provided with several guide marks 102, which are located at both ends of the slide groove, so as to facilitate the operation according to the angle of the hydraulic support. During use, pressing down on the control lever causes the pressing block 208 to apply pressure to the spring 209, causing the spring 209 to contract within the sleeve 203. This indirectly moves the two limiting posts 205 on the control lever from the top of the adjustment groove 206 to the bottom of the adjustment groove 206 and into the guide groove 207, indirectly releasing the self-locking of the control lever. This allows the control lever to swing freely according to several guide marks 102, thereby controlling the hydraulic support. When the operation of the control lever is stopped and the control lever is released, the rebound of the spring 209 will push the control lever above the pressing block 208 to the top, causing the two limiting posts 205 on the control lever to re-enter the adjustment groove 206.

[0019] Controlling the ball 103 Figure 1 As shown, The top of the control lever is equipped with a control ball 103, which prevents the sharp edges of the control lever from touching the hand when the operator operates the control lever, thereby improving comfort. The top surface of the limit box is curved, which prevents the control ball 103 on the control lever from contacting the top of the limit box. Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
