Description

Technical Field

[0001] The present application relates to the technical field of underground support equipment, and in particular to an ultra-large mining height transition hydraulic support. Background Art

[0002] Transition hydraulic supports are primarily used to support and stabilize the transition between the fully mechanized caving working face and the roadway. They are typically installed at the head and tail of a conveyor or on a shearer. They effectively support the roof of the goaf, maintaining a safe working space on the working face. By supporting the roof of the coal face, they prevent flying waste and goaf collapse, protecting workers' lives.

[0003] During the use of the transition hydraulic support, due to its heavy weight, it needs to be transferred by a traction device. When the transition hydraulic support moves inside the tunnel, the base of the transition hydraulic support will produce greater friction with the ground, requiring greater traction force and the output power of the traction machine. In addition, when the ground of the tunnel is uneven, the base of the transition hydraulic support is prone to getting stuck, affecting the normal movement of the transition hydraulic support.

[0044] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0045] The present application provides an ultra-large mining height transition hydraulic support, comprising: a support arm 800, a connecting shaft 801, a base 100, a bottom support plate 200, a first telescopic component 600, a side support plate 300 and a top beam 400. The top of the base 100 is hinged to the bottom of the bottom support plate 200, the top of the bottom support plate 200 is rotatably connected to the bottom of the side support plate 300, and the top of the side support plate 300 is hinged to one end of the top beam 400.

[0046] The top of the base 100 is hinged with two sets of first telescopic components 600, and the output ends of the first telescopic components 600 are hinged to the bottom of the top beam 400.

[0047] Two support arms 800 are arranged at intervals in the width direction of the base 100. A connecting shaft 801 is installed between the bottom ends of the two support arms 800, and the connecting shaft 801 is rotatably connected to the top of the base 100.

[0048] Among them, the base 100 includes a support plate 102, a mounting plate 103, wheels 104 and a lifting and folding member. One end of the lifting and folding member passes through the support plate 102 to be installed on the connecting shaft 801, and the other end of the lifting and folding member is connected to the mounting plate 103. Multiple wheels 104 are installed at the bottom of the mounting plate 103.

[0049] The ultra-large mining height transition hydraulic support implemented in the present application is provided with liftable wheels 104 and a base so as to move and fix the support.

[0050] The output end of the first telescopic member 600 is hinged to the bottom of the top beam 400. The extension and retraction of the first telescopic member 600 drives the top beam 400 up and down. During this process, the bottom support plate 200 deflects relative to the base 100, and the side support plates 300 deflect relative to the bottom support plate 200 and the top beam 400. Two support arms 800 are hingedly connected to the lower surface of the side support plates 300. A connecting shaft 801 is fixedly mounted between the bottom ends of the two support arms 800 and is rotatably connected to the top of the base 100. The support arms 800 support the side support plates 300.

[0051] Wheels 104 are provided on both the front and rear sides of the mounting plate 103. A lifting and folding member is provided between the mounting plate 103 and the support plate 102. A towing hook 105 may be welded to the right side of the support plate 102. By folding the lifting and folding member, the mounting plate 103 and wheels 104 are moved upward, lifting them off the ground and allowing the support plate 102 to contact the ground, thus ensuring a more stable placement of the base 100. By deploying the lifting and folding member, the mounting plate 103 is moved downward, allowing the wheels 104 to contact the ground and the support plate 102 to lift off the ground, thereby facilitating the movement of the hydraulic support and making it easier to move the base 100 on the ground.

[0052] The ultra-large mining height transition hydraulic support implemented in this application is configured with liftable wheels 104 and a base. The wheels are lowered to contact the ground so as to move the support, and the wheels are raised to contact the ground so as to fix the support, thereby facilitating the movement and fixation of the support.

[0053] In some embodiments, the base 100 further includes a pad 101 and an L-shaped slide 107, and the support plate 102 is installed with pads 101 on both sides in the width direction of the base 100, and the connecting shaft 801 is provided with spiral grooves in opposite directions at the front and rear halves in the width direction of the base 100, and the lifting and folding member includes two threaded collars 106, and the two threaded collars 106 are respectively threadedly connected to the front and rear halves of the connecting shaft 801, wherein the spiral directions of the spiral grooves corresponding to the two threaded collars 106 are opposite, so that the rotation of the connecting shaft drives the threaded collars 106 to move closer to or away from each other, and an L-shaped slide 107 is fixedly installed at the bottom of each threaded collar 106, and a slide groove 108 is opened through the top of the support plate 102, and the vertical parts of the two L-shaped slides 107 are both slidably connected in the slide groove 108, and the horizontal part of the L-shaped slide 107 is fitted to the bottom of the support plate 102;

[0054] Two groups of scissor fork assemblies are arranged between the two L-shaped slides 107 . The two groups of scissor fork assemblies are distributed on the left and right, and the bottom end of each group of scissor fork assemblies is slidably connected to the top of the mounting plate 103 .

[0055] Specifically, if Figures 1 to 8 As shown, the base 100 comprises two base plates 101, with a support plate 102 fixedly mounted between the tops of the two base plates 101. A mounting plate 103 is mounted below the mounting plate 103. Wheels 104 are mounted on both the front and rear sides of the mounting plate 103. A lifting and folding mechanism is installed between the mounting plate 103 and the support plate 102. A towing hook 105 is welded to the right side of the support plate 102. The lifting and folding mechanism folds, allowing the mounting plate 103 and wheels 104 to be stored between the two base plates 101, contacting the base plates 101 and making the base 100 more stable. The lifting and folding mechanism unfolds, driving the mounting plate 103 downward, allowing the wheels 104 to contact the ground, while the base plate 101 rises. This makes it easier to move the base 100 on the ground. The front and rear halves of the support arm 800 are formed with spiral grooves running in opposite directions, each with a single turn. The lifting and folding member includes two threaded collars 106, which are respectively threadedly connected to the front and rear halves of the connecting shaft 801. Specifically, Figures 1 to 8As shown, a sliding ball is provided on the inner wall of the threaded collar 106, which slides into the spiral groove. An L-shaped slide 107 is fixedly mounted at the bottom of each threaded collar 106. A slide groove 108 is provided through the top of the support plate 102. The vertical portions of the two L-shaped slides 107 are both slidably connected within the slide groove 108, and the horizontal portions of the L-shaped slides 107 are affixed to the bottom of the support plate 102. The slide groove 108 guides the L-shaped slides 107 and the threaded collar 106. As a result, when the first telescopic component 600 extends and retracts, driving the top beam 400 to rise and fall, the support arm 800 and the connecting shaft 801 deflect relative to the base 100. The threaded connection between the threaded collar 106 and the connecting shaft 801 drives the two threaded collars 106 toward each other, causing the two L-shaped slides 107 to approach each other. Two sets of scissor fork assemblies are arranged between the two L-shaped slides 107. The two sets of scissor fork assemblies are distributed on the left and right, and the bottom end of each set of scissor fork assemblies is slidably connected to the top of the mounting plate 103. When the two L-shaped slides 107 approach each other, the scissor fork assemblies are driven to unfold, thereby driving the mounting plate 103 to move downward.

[0056] The ultra-large mining height transition hydraulic support implemented in the present application extends the first telescopic component 600, driving the top beam 400 to rise upward, the bottom support plate 200 and the side support plate 300 to deflect, and the support arm 800 supports the side support plate 300. During this process, the support arm 800 deflects relative to the base 100, and the connecting shaft 801 rotates; it drives the two threaded rings 106 to approach each other, and the two L-shaped slides 107 to approach each other, thereby driving the rotating arm 109 and the rotating arm 2 110 to unfold, so that the mounting plate 103 moves downward, the wheel 104 contacts the ground to support the mounting plate 103, and the pad 101 and the support plate 102 are lifted upward; thereby achieving the purpose of arranging the liftable wheels 104 on the base, and the transition hydraulic support is placed stably and easy to transfer.

[0057] In some embodiments, each of the scissors fork assemblies includes a pivot arm 109, a pivot arm 2 110 and a slider 111. The pivot arm 109 and the pivot arm 2 110 are hinged to each other at the center. The top of the pivot arm 109 and the top of the pivot arm 2 110 are respectively hinged to two L-shaped slides 107. The bottom of the pivot arm 109 and the bottom of the pivot arm 2 110 are both hinged to the slider 111. A slide rail 112 is fixedly installed on the top of the mounting plate 103. The slide rail 112 is arranged along the front and rear direction. The two sliders 111 are slidably connected to the slide rail 112.

[0058] Sliders 111 are hingedly connected to the bottom ends of both pivot arms 109 and 110. A slide rail 112, extending in the front-to-rear direction, is fixedly mounted on the top of mounting plate 103. Sliders 111 are slidably connected to these rails. This design allows sliders 111 to slide linearly on these rails, thereby guiding the direction of movement of the pivot arms and ensuring the stability and accuracy of the scissor fork assembly during movement.

[0059] For example, when the L-shaped slides 107 approach each other, the rotating arm 109 and the rotating arm 2 110 will rotate around the central hinge point, and at the same time, the slider 111 slides toward the middle on the slide rail 112, and the scissors fork assembly contracts; conversely, when the L-shaped slides 107 move away from each other, the rotating arm rotates, the slider 111 slides toward both ends on the slide rail 112, and the scissors fork assembly expands.

[0060] This makes it easier for the support arm 800 to rotate the connecting shaft 108 as the hydraulic support moves forward or supports, so that the L-shaped slides 107 move closer to or farther away from each other, thereby allowing the scissor fork assembly to extend and retract in the up and down directions.

[0061] Furthermore, a guide rod is provided between the two pads, the guide rod is connected to the pads, and the end of the L-shaped slide 107 away from the connecting shaft 801 can be slidably mounted on the guide rod, so that the L-shaped slide 107 can move closer to or away from each other in the front and rear directions more smoothly.

[0062] In some embodiments, the ultra-large mining height transition hydraulic support also includes a second telescopic component 700 and an upper support plate 500. The upper support plate 500 is hinged at the right end of the top beam 400, and two groups of second telescopic components 700 are hinged on the lower surface of the right half of the top beam 400. The output end of the second telescopic component 700 is hinged on the left side of the upper support plate 500.

[0063] Two sets of second telescopic components 700 are hinged on the lower surface of the right half of the top beam 400. The output end of the second telescopic component 700 is hinged on the left side of the upper support plate 500. Through the extension and contraction of the second telescopic component 700, the upper support plate 500 is driven to deflect relative to the top beam 400 to protect the working surface.

[0064] In some embodiments, the ultra-large mining height transition hydraulic support further includes a liquid outlet pipe 701, a liquid inlet pipe 702, a fixing seat 703, a fixed pulley 1 704, a fixed pulley 2 705 and a winding assembly 900.

[0065] Each group of the second telescopic parts 700 is connected to a liquid outlet pipe 701 and a liquid inlet pipe 702, and the liquid outlet pipe 701 and the liquid inlet pipe 702 are connected, and two fixing seats 703 are fixedly installed at the bottom of the top beam 400, and the liquid outlet pipe 701 and the liquid inlet pipe 702 are fixed on the fixing seats 703. Two groups of fixed pulleys 1 704 are provided at the bottom of the top beam 400, and two groups of fixed pulleys 2 705 are provided at the top of the base 100. A winding assembly 900 is provided on the upper surface of the right half of the base 100, and the liquid outlet pipe 701 and the liquid inlet pipe 702 pass around the surfaces of fixed pulleys 1 704 and fixed pulleys 2 705, and are wound on the winding assembly 900 to keep the liquid inlet pipe 702 and the liquid outlet pipe 701 taut. Each set of second telescopic components 700 is connected to a liquid outlet pipe 701 and a liquid inlet pipe 702. The outer surfaces of the liquid outlet pipe 701 and the liquid inlet pipe 702 are fixed together.

[0066] Specifically, if Figures 1 to 8 As shown, the liquid outlet pipe 701 and the liquid inlet pipe 702 can be fixed with a cable tie to prevent them from getting tangled. Two fixing seats 703 are fixedly mounted on the bottom of the top beam 400, and the fixing seats 703 correspond one-to-one with the second telescopic member 700. The liquid outlet pipe 701 and the liquid inlet pipe 702 are fixed through the fixing seats 703, so that the portions of the liquid outlet pipe 701 and the liquid inlet pipe 702 located between the second telescopic member 700 and the fixing seats 703 are stably arranged at the bottom of the top beam 400. Two sets of fixed pulleys 704 are provided at the bottom of the top beam 400, and two sets of fixed pulleys 705 are provided at the top of the base 100. A winding assembly 900 is provided on the upper surface of the right half of the base 100. The liquid outlet pipe 701 and the liquid inlet pipe 702 pass over the surfaces of the fixed pulleys 704 and 705 and are wound up on the winding assembly 900. The liquid outlet pipe 701 and the liquid inlet pipe 702 are steered by fixed pulley 1 704 and fixed pulley 2 705 so that they can be wound around the reel assembly 900 for storage. The reel assembly 900 exerts a pulling force on the liquid outlet pipe 701 and the liquid inlet pipe 702, thereby preventing the portions of the liquid outlet pipe 701 and the liquid inlet pipe 702 between the support plate 102 and the top beam 400 from becoming disorganized during the raising and lowering of the top beam 400. The first telescopic member 600 is mounted on the top of the base 100, and the hydraulic pipes provided on the first telescopic member 600 are relatively short, so there is no need to reel them in to prevent them from becoming disorganized.

[0067] In some embodiments, the winding assembly 900 includes two supports 901 fixedly mounted on the top of the base 100, a collar 902 fixedly mounted between the two supports 901, a rotating shaft 904 rotatably connected through the two supports 901, and a coil spring 903 fixedly mounted between the inner wall of the collar 902 and the circumferential surface of the rotating shaft 904;

[0068] Hollow rollers 905 are fixedly mounted at both ends of the rotating shaft 904 . The liquid outlet pipe 701 and the liquid inlet pipe 702 pass through the surface of the hollow roller 905 and extend into the interior of the hollow roller 905 .

Thus, by tightening the bolt 924, the slide 923 slides within the linear groove 921, and the slide posts 925 slide within the guide groove 920 and the inclined groove 926. The slide posts 925 squeeze the inner wall of the inclined groove 926, pushing the transverse seat 917 to move left and right.

[0080] Among them, an annular groove is formed between the retaining ring 910 and the connecting pipe 911, and the through hole 1 907 is connected to the annular groove.
