Description

Technical Field

[0001] This invention relates to a self-moving component and a fully mechanized mining support, belonging to the field of mining equipment, specifically to support equipment. Background Technology

[0002] Fully mechanized mining supports are support devices used to support the top and sides of a mine during mining operations. They are typically transported to the area requiring support via rails and then moved to the support point using hydraulic rods and chains. The process involves either fixing the end of the chain and then retracting the hydraulic rod to move the support, or directly using the hydraulic rod to push against a fixed surface to move the support. However, this method is cumbersome and time-consuming, and the support is prone to tipping over, causing injuries or fatalities. Therefore, a new method has emerged that uses a portion of the support itself as a fixed surface, utilizing hydraulic rods in conjunction with the fixed portion for stepping movement. However, this method still suffers from low efficiency and significant energy waste due to the need to resist friction.

[0003] For example, the Chinese invention patent (application number: 201910465248.8) discloses a "lightweight self-propelled stepping advance hydraulic support group for fully mechanized mining faces." Its specification states that this group addresses many shortcomings of existing single hydraulic props combined with π-shaped beams and traditional support and support-shield type advance hydraulic supports. It employs a series-connected advance hydraulic support group, with each group consisting of 5-7 structurally identical lightweight hydraulic support units connected sequentially. Adjacent hydraulic support groups are connected by stepping telescopic cylinders and two-linkage rods. Two or more sets are arranged on each side of the end roadway of the fully mechanized mining face. Through stepping self-movement, it effectively supports the roadway within the advance control range of the fully mechanized mining face. This patent can corroborate the deficiencies of existing technologies.

[0004] Therefore, we have made improvements to this by proposing a self-moving component and a fully mechanized mining support. Summary of the Invention

[0005] (a) The technical problem to be solved by the present invention is that there is low efficiency and a large amount of wasted energy.

The end of the hydraulic tie rod is fixedly provided with a mounting block, and a hook is fixedly provided below the mounting block.

[0011] A fully mechanized mining support includes a support rod, which is fixedly connected to the top of a transition plate and located inside a movable groove. A first guard plate is hinged to the top of the support rod. A second guard plate is provided at the front end of the first guard plate. An adjustable guard plate is provided at the front end of the second guard plate. A support control frame is provided at the bottom end of the second guard plate. Several force-enhancing components are provided at the bottom end of the support control frame. Temporary support components are provided on both sides of the force-enhancing components. An auxiliary hydraulic rod is hinged to the top of the transition plate and located behind the support rod. The top end of the auxiliary hydraulic rod passes through the movable groove and connects to the rear end of the bottom of the first guard plate. A first support hydraulic rod and a second support hydraulic rod are hinged to the top of a sliding plate. The top end of the first support hydraulic rod is connected to the first guard plate, and the top end of the second support hydraulic rod is connected to the second guard plate.

[0012] The second guard plate includes a plate body hinged to the front end of the first guard plate. A placement groove is provided at the front end of the plate body.

A limit slide groove is provided below the placement groove.

[0013] The adjustable guard plate includes a movable frame that slides in the placement groove. Several rotating grooves are provided on both sides of the movable frame.

A passive rod is also hinged to the end of the second limiting rod, and the end of the passive rod is hinged to the front end of the bottom of the movable frame.

[0016] (III) Beneficial Effects The self-moving component and fully mechanized mining support provided by this invention have the following advantages: 1. By using the self-moving component, when moving on a flat surface, the walking wheels contact the ground, the support frame is lifted, and the drive component drives the walking wheels to rotate, thereby moving the support frame. This achieves roller movement. Using rollers on a flat surface can significantly increase the speed of the support frame movement, and the friction between the rollers and the ground is smaller, resulting in greater energy utilization. When turning is required, the support frame provides support, the moving component is lifted and does not contact the ground, the drive component drives the moving component to rotate and change the direction of the walking wheels, then the moving component provides support, the support frame does not contact the ground, the reverse rotation of the drive component makes the base rotate, the first gear disk re-meshes with the first bevel gear, and the turning is achieved. It does not require the traditional method of turning using hydraulic rods on both sides and iron chains, which greatly improves the turning efficiency. During the stepping movement, the rolling direction of the traveling wheels is perpendicular to the direction of movement. The base is raised, the moving component contacts the ground, and the driving hydraulic rod drives the support frame to move forward. Then the support frame descends and contacts the ground, the moving component is raised, and the driving hydraulic rod drives the transition plate to move forward, thus realizing the stepping forward movement. The stepping forward movement does not require dragging on the ground, reducing friction and the impact of the ground on the movement. It also protects the support base and the ground, solving the problems of low efficiency and large energy waste in the movement of fully mechanized mining supports in the existing technology. 2. By using the auxiliary hydraulic rod, the first support hydraulic rod, and the second support hydraulic rod in coordination, when the base needs to be lifted, the auxiliary hydraulic rod remains stationary, while the first and second support hydraulic rods shorten, thus lifting the base; when the moving component needs to be lifted, the auxiliary hydraulic rod remains stationary, while the first and second support hydraulic rods extend, thus lifting the moving component. 3. Through the coordinated use of the set support control frame and adjustable guard plate, when the drive block moves forward, the drive block pushes the active rod to rotate the first limiting rod, the extension rod pushes the second limiting rod to rotate, and then pushes the passive rod to move the adjustable guard plate forward and extend it out of the placement slot. When the support plate extends out of the placement slot, the coil spring causes the rotating shaft to rotate, and the support plate rotates to the top of the rotating shaft. The support plate supports the top of the mine, and the second limiting rod and the passive rod support the adjustable guard plate to prevent the end of the adjustable guard plate from extending too far and bending downward. During the excavation process, the mine continuously widens, and the widening position is supported. 4. Through the set drive component, when the support frame moves upward, it drives the drive motor to move upward. The second bevel gear meshes with the first meshing groove. When the drive motor runs, it drives the first gear disk to rotate through the second bevel gear. The first gear disk drives the third pulley to rotate through the first bevel gear. The third pulley drives the first pulley to rotate, thereby causing the walking wheel to rotate through the transmission shaft. When the support frame moves downward and the moving component moves upward, the third bevel gear meshes with the second meshing groove. When the drive motor runs, it drives the second pulley to rotate. The second pulley drives the control disk to rotate through the transmission rope, thereby causing the moving component to turn. This realizes that the moving component and the walking wheel can be driven to rotate separately through a single drive source. 5. Through the set temporary support components and force-increasing components, the No. 2 hydraulic push rod pushes the connecting rod, and the connecting rod pushes the drive rod to make the end of the drive rod open to both sides. The angle between the No. 2 support rod and the No. 1 support rod increases. Since the connecting block is fixed, the strip plate moves downward, so the rack moves downward. When the rack moves downward, it drives the transmission gear to rotate. When the transmission gear rotates, it drives the connecting plate to rotate. The connecting plate drives the L-shaped rod to rotate, so that the temporary support plate flips to the side of the plate body. The auxiliary rod limits the angle of the temporary support plate so that the temporary support plate and the plate body are on the same plane, realizing the auxiliary side support of the withdrawal support. 6. Through the set force-enhancing components, as the drive rod pushes the No. 2 support rod and the No. 1 support rod to open, the strip plate pulls the moving column downward with increasing force, thereby increasing the force and enabling the temporary support plate to provide more effective support for the top of the mine.

The second bevel gear 128 meshes with the first meshing groove 126. When the drive motor 121 runs, it drives the first gear disc 122 to rotate through the second bevel gear 128. The first gear disc 122 drives the third pulley 124 to rotate through the first bevel gear 125. The third pulley 124 is connected to the first pulley 116 through a transmission belt. The third pulley 124 drives the first pulley 116 to rotate, thereby causing the walking wheel 113 to rotate through the transmission shaft 115. When the support frame 101 moves downward and the moving component 11 moves upward, the third bevel gear 129 meshes with the second meshing groove 127. When the drive motor 121 runs, it drives the second pulley 123 to rotate.

The front end of the plate body 41 is provided with a placement groove. The rear end of the placement groove is embedded with a first hydraulic push rod 42. The telescopic end of the first hydraulic push rod 42 is fixedly provided with a drive block 44 located inside the placement groove. A limit slide groove 43 is provided below the placement groove, and the adjustable guard plate 5 moves inside the placement groove.

[0027] like Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, the adjustable guard plate 5 further includes a movable frame 51 that slides in the placement groove. Several rotating grooves 52 are provided on both sides of the movable frame 51. Several rotating shafts 53 are provided inside the movable frame 51. A pad 54 is fixedly provided on the side of the rotating shaft 53. A support plate 55 is fixedly provided on the side of the pad 54 away from the rotating shaft 53. The two ends of the rotating shaft 53 are respectively located in the rotating grooves 52 on both sides. The rotating shaft 53 and the rotating groove 52 are connected by a coil spring. When the support plate 55 extends out of the placement groove, the coil spring causes the rotating shaft 53 to rotate, and the support plate 55 rotates above the rotating shaft 53, providing support above the mine shaft. When the support plate 55 retracts into the placement groove, the movable frame 51 blocks the support plate 55, causing the rotating shaft 53 to rotate.

The end of the second limiting rod 134 is also hinged to a passive rod 135. The end of the passive rod 135 is hinged to the front end of the bottom of the movable frame 51. When the driving block 44 moves forward, the driving block 44 pushes the active rod 131 to rotate the first limiting rod 132. The extension rod 133 pushes the second limiting rod 134 to rotate, which in turn pushes the passive rod 135 to move the adjustable guard plate 5 forward and extend it out of the placement slot. The second limiting rod 134 and the passive rod 135 support the adjustable guard plate 5 to prevent the end of the adjustable guard plate 5 from extending too far and bending downward.

[0029] like Figure 8 , Figure 9 and Figure 11 As shown, in a preferred embodiment, based on the above method, the temporary support assembly 14 further includes a mounting plate 141 fixedly connected to the bottom end of the plate 41.

A temporary support plate 145 is provided, and a compensating rod 148 is hinged to the end of the auxiliary rod 144. The end of the compensating rod 148 is fixedly connected to the temporary support plate 145. When the transmission gear 147 rotates, it drives the connecting plate 142 to rotate. The connecting plate 142 drives the L-shaped rod 143 to rotate, causing the temporary support plate 145 to flip to the side of the plate 41. The auxiliary rod 144 limits the angle of the temporary support plate 145 so that the temporary support plate 145 and the plate 41 are on the same plane, thus achieving auxiliary side support for the withdrawal support.

Movable columns 158 are fixedly provided at both ends of the top of the strip plate 151. A rack 159 is fixedly provided at the top of the movable columns 158.

A connecting rod 153 located above the strip plate 151 is fixedly provided at the telescopic end of the second hydraulic push rod 152. Drive rods 154 are hinged to both ends of the connecting rod 153. The end of the drive rod 154 is hinged to... There are two support rods 156 and one support rod 155. The end of the first support rod 155 is hinged to the strip plate 151. The end of the second support rod 156 is hinged to a connecting block 157. The connecting block 157 is fixedly connected to one side of the mounting plate 141. The second hydraulic push rod 152 pushes the connecting rod 153, and the connecting rod 153 pushes the drive rod 154, causing the end of the drive rod 154 to spread open to both sides. The angle between the second support rod 156 and the first support rod 155 increases. Since the connecting block 157 is fixed, the strip plate 151 moves downward, thereby causing the rack 159 to move downward. When the rack 159 moves downward, it drives the transmission gear 147 to rotate.

[0031] Example 3: The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods. Specifically, during operation / use, this self-moving component and fully mechanized mining support move the fully mechanized mining support to the installation area, and then move itself to the installation point. The movement method is selected according to the ground conditions. When moving on flat ground, the traveling wheels 113 contact the ground, the support frame 101 is raised, and the upward movement of the support frame 101 drives the drive motor 121 to move upward. The second bevel gear 128 meshes with the first meshing groove 126. When the drive motor 121 runs, it drives the first gear disk 122 to rotate through the second bevel gear 128. The first gear disk 122 drives the third pulley 124 to rotate through the first bevel gear 125. The third pulley 124 drives the first pulley 116. The rotation of the drive shaft 115 causes the traveling wheels 113 to rotate, which in turn drives the drive assembly 12 to rotate the traveling wheels 113, thus moving the support frame. This achieves roller movement. On flat ground, using rollers can significantly increase the speed of the support frame's movement, and the friction between the rollers and the ground is smaller, resulting in greater energy utilization. On uneven ground, the rolling direction of the traveling wheels 113 is perpendicular to the direction of movement, the base 1 rises, the moving assembly 11 contacts the ground, the drive hydraulic rod 18 drives the support frame 101 to move forward, then the support frame 101 descends to contact the ground, the moving assembly 11 rises, the drive hydraulic rod 18 drives the transition plate 10 to move forward, thus achieving step-like forward movement. The step-like forward movement eliminates the need for dragging on the ground, reducing friction and the impact of the ground on movement, while also protecting the base 1 and the ground. During turning, the support frame 101 provides initial support, lifting the moving component 11 so it doesn't contact the ground. As the support frame 101 lowers and the moving component 11 rises, the third bevel gear 129 engages with the second meshing groove 127. The drive motor 121 then rotates the second pulley 123, which, via the transmission rope 114, drives the control disc 112 to rotate, thus turning the moving component 11. The drive component 12 then rotates the moving component 11, changing the direction of the traveling wheels 113, and finally... The support frame 101 does not contact the ground. The reverse rotation drive assembly 12 causes the base 1 to rotate, and the first gear disk 122 re-engages with the first bevel gear 125 to achieve steering. This eliminates the need for the traditional method of steering using hydraulic rods and chains on both sides, greatly improving steering efficiency. When stepping and roller movement are not applicable, the backup assembly 17 is used to move in the traditional way. The hook is used to hold a fixed object in front, and then the hydraulic rods are shortened to pull the support forward. During stepping and steering, when the base 1 needs to be lifted, the auxiliary hydraulic rod 16 remains stationary, and the first support hydraulic rod 8 and the second support hydraulic rod 9 are shortened to lift the base 1.When the movable component 11 needs to be lifted, the auxiliary hydraulic rod 16 remains stationary, while the first support hydraulic rod 8 and the second support hydraulic rod 9 extend to complete the lifting of the movable component 11. After the fully mechanized mining support is moved to the installation location, the auxiliary hydraulic rod 16, the first support hydraulic rod 8, and the second support hydraulic rod 9 extend, and the support rod 2 is stretched and lengthened. By adjusting the first and second hydraulic rods, the angles of the second guard plate 4 and the auxiliary guard plate 6 are changed, so that the first guard plate 3, the second guard plate 4, and the auxiliary guard plate 6 adhere to the inner wall of the mine. During excavation, the mine continuously widens during the excavation process of the fully mechanized mining face, driving... Block 44 pushes the active rod 131, causing the first limiting rod 132 to rotate. The extension rod 133 pushes the second limiting rod 134 to rotate, which in turn pushes the passive rod 135, causing the adjustable guard plate 5 to move forward and extend from the placement slot. When the support plate 55 extends from the placement slot, the coil spring causes the rotating shaft 53 to rotate, and the support plate 55 rotates above the rotating shaft 53. The support plate 55 provides support for the mine shaft. The second limiting rod 134 and the passive rod 135 support the adjustable guard plate 5, preventing the end of the adjustable guard plate 5 from extending too far and bending downwards, thus providing support for the widened area. When removing the supports, remove every other fully mechanized mining support. After removing the supports on both sides of the fully mechanized mining support, the second hydraulic push rod 152 pushes the connecting rod 153. The connecting rod 153 pushes the drive rod 154, causing the end of the drive rod 154 to spread out to both sides. The angle between the second support rod 156 and the first support rod 155 increases. Since the connecting block 157 is fixed, the strip plate 151 moves downward, thereby causing the rack 159 to move downward. When the rack 159 moves downward, it drives the transmission gear 147 to rotate. When the transmission gear 147 rotates, it drives the connecting plate 142 to rotate. 2. The L-shaped rod 143 rotates, causing the temporary support plate 145 to flip to the side of the plate 41. The auxiliary rod 144 limits the angle of the temporary support plate 145, ensuring that the temporary support plate 145 and the plate 41 are on the same plane. This achieves the auxiliary support at the side position when the support is removed. The fully mechanized mining support needs to be moved onto the track after being placed on the moving platform. This process can use a C-shaped moving platform. First, the base 1 is moved up to support the moving component 11. The two ends are inserted into the sides of the moving component 11. Then, the base 1 is moved down to lift the moving component 11 off the ground, making it easier for the support to be placed on the platform.
