Description

Technical Field

[0001] This invention relates to the field of bending equipment technology, specifically to a continuous bending device for a coal mining machine hydraulic support. Background Technology

[0002] Currently, in order to improve the automation and mechanization of underground coal mining, coal mining machines are usually used to complete underground coal mining operations. The hydraulic support components are responsible for the pushing and moving of the scraper conveyor, so that the scraper conveyor advances along the mining direction of the working face, thereby realizing continuous coal cutting of the working face and realizing the automated control of the fully mechanized mining face.

[0003] The hydraulic support of a coal mining machine is a rod-shaped structure with multiple bending inflection points. During the processing, it is necessary to bend the designed bending points using a bending device. Current bending equipment cannot achieve continuous bending during use, requiring repeated lifting and lowering of the support rods to adjust their position. The support also needs to be positioned before each bending. Moreover, the hydraulic support lacks positioning components, which makes the hydraulic support prone to angular deviation during the bending process, resulting in very low processing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a continuous bending device for hydraulic supports of coal mining machines, which aims to solve the problems of bending equipment being unable to connect and bending and lacking positioning components.

[0005] To achieve the above effects, the technical solution adopted by the present invention is as follows: a continuous bending device for a hydraulic support of a coal mining machine, comprising a bending body, a groove being provided on one side wall of the bending body, a fixing plate being fixedly connected to the upper surface of the bending body, and a guide component being provided on one side of the fixing plate;

[0006] The guiding component includes a first mounting plate, which is located on one side wall of the fixed plate and is connected to the bending body. A first telescopic rod is fixed to the left and right ends of one side wall of the first mounting plate, and a placement plate is fixed to the output end of one side wall of the first telescopic rod.

[0007] A material pusher assembly is fixed to the upper surface of the bending body, and a material guide assembly is provided inside the placement plate.

[0008] Preferably, the pushing assembly includes a second mounting plate, which is positioned on the upper surface of the bending body. A pair of second telescopic rods are fixedly connected to one side wall of the second mounting plate. A pushing plate is fixedly connected to the output end of one side wall of the second telescopic rod. A U-shaped groove is formed on the inner wall of the pushing plate. A connecting seat is fixedly connected inside the groove. A bending assembly is provided on one side wall of the connecting seat.

[0009] Preferably, the inner sidewall of the fixing plate is provided with a first sliding groove, a sliding rod is fixedly connected inside the first sliding groove, and a first slider is slidably connected to the outer wall of the sliding rod.

[0010] Preferably, the material guiding assembly includes a third chute, which is positioned on the inner wall of the placement plate. An air pump is fixedly connected to one side wall of the placement plate, and an air rod is fixedly connected to the output end of the air pump. An arc-shaped connecting plate is fixedly connected to one side wall of the air rod.

[0011] Preferably, a mounting block is fixed to the upper surface of the bending body, a third telescopic rod is fixed to one side wall of the mounting block, and a first clamping plate is fixed to the output end of one side of the third telescopic rod.

[0012] Preferably, a second sliding groove is fixedly connected to the upper surface of the bending body, a second slider is slidably connected inside the second sliding groove, and the second slider is connected to the push plate. A toothed plate is fixedly connected to one side wall of the second slider.

[0013] Preferably, a fixing ring is fixedly connected to one side wall of the connecting seat, a rotating shaft is rotatably connected inside the fixing ring, a connecting ring is rotatably connected to the outer wall of the upper surface of the rotating shaft, and a connecting rod is fixedly connected to one side wall of the connecting ring.

[0014] Preferably, a connecting plate is fixed to one side wall of the connecting rod, a slot is formed on the inner wall of the connecting plate, a pair of rotating rods are rotatably connected inside the slot, a pair of turntables are rotatably connected to the upper surface of the pair of rotating rods, a second clamping plate is fixed to the lower surface of the pair of rotating rods, and a rotating gear is rotatably connected to the outer wall of the lower surface of the rotating shaft.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. Through the setting of the guiding component, the use of the first mounting plate and the first telescopic rod allows the placement plate to reciprocate during use, thereby enabling the arc-shaped connecting plate inside the placement plate to drive the hydraulic support to bend. Through the setting of the pushing component, due to the use of a U-shaped groove, during use, the operator puts the connector on one side of the hydraulic support into the U-shaped groove. Driven by the second telescopic rod, the hydraulic support can reciprocate back and forth. Furthermore, pushing the hydraulic support during use can also retract the bent hydraulic support, making it convenient for the operator to remove the bent hydraulic support.

[0017] 2. Through the setting of the material guiding component, the air pump drives the air rod to reciprocate, thereby bending the arc-shaped connecting plate and the hydraulic support. This facilitates the bending of the hydraulic support. Combined with the bending component, the hydraulic support can be bent continuously. The bending component, with its toothed plate, meshes with the rotating gear during use, causing the rotating shaft to rotate. The hydraulic support is placed in the slot, and two sets of turntables drive the rotating rod to clamp the hydraulic support with the second clamping plate. The second telescopic rod drives the push plate to move, causing the second slider at the lower end of the push plate to move the toothed plate, making it mesh with the rotating gear. During use, under the action of the toothed plate, the rotating shaft with the connecting ring rotates, allowing the placement plate to move to the other side, enabling it to rotate 180 degrees. When the second telescopic rod resets, the toothed plate resets, causing the placement plate on the other side to reset using the rotating gear and rotating shaft. Attached Figure Description

[0025] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1:

[0027] Please see Figures 1 to 5 As shown, this embodiment discloses a continuous bending device for a coal mining machine hydraulic support, including a bending body 1. The device is characterized in that: a groove 2 is provided on one side wall of the bending body 1, a fixing plate 3 is fixedly connected to the upper surface of the bending body 1, and a guide component is provided on one side of the fixing plate 3.

[0028] The guiding component includes a first mounting plate 4, which is located on one side wall of the fixed plate 3 and is connected to the bending body 1. The left and right ends of one side wall of the first mounting plate 4 are fixedly connected to a first telescopic rod 5, and the output end of one side wall of the first telescopic rod 5 is fixedly connected to a placement plate 6.

[0029] A material pushing assembly is fixed to the upper surface of the bending body 1, and a material guiding assembly is provided inside the placement plate 6. Since this device adopts the setting of the guiding assembly, the first telescopic rod 5 drives the placement plate 6 to move back and forth, so that the arc-shaped connecting plate 17 inside the placement plate 6 can guide the hydraulic support to bend. With the help of the bending assembly, the hydraulic support can be continuously bent.

[0030] The material pushing assembly includes a second mounting plate 7, which is located on the upper surface of the bending body 1. A pair of second telescopic rods 8 are fixed to one side wall of the second mounting plate 7. A push plate 9 is fixed to the output end of one side wall of the second telescopic rod 8. A U-shaped groove 10 is opened on the inner wall of the push plate 9. A connecting seat 18 is fixed inside the groove 2. A bending assembly is provided on one side wall of the connecting seat 18. Due to the material pushing assembly, when the device is in use, the hydraulic support is placed into the U-shaped groove 10, thereby restricting the hydraulic support inside the U-shaped groove 10. Under the drive of the second telescopic rods 8, the hydraulic support is automatically fed during bending and reset after bending is completed, thus facilitating material removal by the operator.

[0031] The inner sidewall of the fixed plate 3 is provided with a first sliding groove 11. A sliding rod 12 is fixedly connected inside the first sliding groove 11. The outer wall of the sliding rod 12 is slidably connected to a first slider 13. Since the first slider 13 is set at the left and right ends on one side of the push plate 9, the push plate 9 can be positioned and slid when it drives the hydraulic support to move, thereby avoiding the angle from shifting during use.

[0032] The material guiding assembly includes a second chute 14, which is located on the inner wall of the placement plate 6. An air pump 15 is fixedly connected to one side wall of the placement plate 6, and an air rod 16 is fixedly connected to the output end of the air pump 15. An arc-shaped connecting plate 17 is fixedly connected to one side wall of the air rod 16. With the setting of the material guiding assembly, when in use, the air pump 15 will drive the air rod 16 to operate, thereby extending the arc-shaped connecting plate 17, thus guiding the bending angle of the hydraulic support, and also protecting the bend of the arc-shaped connecting plate 17.

[0033] A mounting block 19 is fixedly connected to the upper surface of the bending body 1. A third telescopic rod 20 is fixedly connected to one side wall of the mounting block 19. A first clamping plate 21 is fixedly connected to the output end of one side of the third telescopic rod 20. Since the third telescopic rod 20 drives the first clamping plate 21, the first clamping plate 21 is squeezed and pressed against the hydraulic support, thereby assisting in bending the hydraulic support.

[0034] The upper surface of the bending body 1 is fixedly connected to a third slide groove 22. The second slider 23 is slidably connected inside the third slide groove 22 and is connected to the push plate 9. A toothed plate 24 is fixedly connected to one side wall of the second slider 23. Due to the third slide groove 22, the second slider 23 connected to the push plate 9 will drive the toothed plate 24 to operate during use, thereby enabling the toothed plate 24 to mesh with the rotating gear 34 for transmission.

[0035] A fixing ring 25 is fixedly connected to one side wall of the connecting seat 18. A rotating shaft 26 is rotatably connected inside the fixing ring 25. A connecting ring 27 is rotatably connected to the outer wall of the upper surface of the rotating shaft 26. A connecting rod 28 is fixedly connected to one side wall of the connecting ring 27. Due to the use of the connecting ring 27 and the connecting rod 28, when the rotating gear 34 rotates, it will drive the rotating shaft 26 to rotate, and cause the placement plate 29 to drive the hydraulic support to bend.

[0036] A connecting plate 29 is fixedly connected to one side wall of the connecting rod 28. A slot 30 is provided on the inner wall of the connecting plate 29. A pair of rotating rods 31 are rotatably connected inside the slot 30. A pair of turntables 32 are rotatably connected to the upper surface of the pair of rotating rods 31. A second clamping plate 33 is fixedly connected to the lower surface of the pair of rotating rods 31. A rotating gear 34 is rotatably connected to the outer wall of the lower surface of the rotating shaft 26. By setting a pair of turntables 32 and rotating rods 31, and by using threaded transmission, the rotating rods 31 drive the second clamping plate 33 to fix the hydraulic support. In conjunction with the rotation of the placement plate 29, the hydraulic support is bent.

[0037] Example 2:

[0038] Please see Figure 1 and Figure 5 As shown, a continuous bending device for a coal mining machine hydraulic support includes a bending body 1, characterized in that: a groove 2 is provided on one side wall of the bending body 1, a fixing plate 3 is fixedly connected to the upper surface of the bending body 1, and a guide component is provided on one side of the fixing plate 3.

[0039] The guiding component includes a first mounting plate 4, which is located on one side wall of the fixed plate 3 and is connected to the bending body 1. The left and right ends of one side wall of the first mounting plate 4 are fixedly connected to a first telescopic rod 5, and the output end of one side wall of the first telescopic rod 5 is fixedly connected to a placement plate 6.

[0040] A material pushing assembly is fixed to the upper surface of the bending body 1, and a material guiding assembly is provided inside the placement plate 6. Since this device adopts the setting of the guiding assembly, the first telescopic rod 5 drives the placement plate 6 to move back and forth, so that the arc-shaped connecting plate 17 inside the placement plate 6 can guide the hydraulic support to bend. With the help of the bending assembly, the hydraulic support can be continuously bent.

[0041] A fixing ring 25 is fixedly connected to one side wall of the connecting seat 18. A rotating shaft 26 is rotatably connected inside the fixing ring 25. A connecting ring 27 is rotatably connected to the outer wall of the upper surface of the rotating shaft 26. A connecting rod 28 is fixedly connected to one side wall of the connecting ring 27. Due to the use of the connecting ring 27 and the connecting rod 28, when the rotating gear 34 rotates, it will drive the rotating shaft 26 to rotate, and cause the placement plate 29 to drive the hydraulic support to bend.

[0042] A connecting plate 29 is fixedly connected to one side wall of the connecting rod 28. A slot 30 is provided on the inner wall of the connecting plate 29. A pair of rotating rods 31 are rotatably connected inside the slot 30. A pair of turntables 32 are rotatably connected to the upper surface of the pair of rotating rods 31. A second clamping plate 33 is fixedly connected to the lower surface of the pair of rotating rods 31. A rotating gear 34 is rotatably connected to the outer wall of the lower surface of the rotating shaft 26. By setting a pair of turntables 32 and rotating rods 31, and by using threaded transmission, the rotating rods 31 drive the second clamping plate 33 to fix the hydraulic support. In conjunction with the rotation of the placement plate 29, the hydraulic support is bent. Moreover, this device can bend the hydraulic support by setting up a guide component, a push component, a guide component, and a bending component.

[0043] In use, the connector of the hydraulic support is first placed into the U-shaped groove 10. During use, the second telescopic rod 8 on one side of the second mounting plate 7 drives the push plate 9 to move. This, in conjunction with the slide rod 12 inside the first slide groove 11, causes the push plate 9 with the first slider 13 to move in a fixed position. As the push plate 9 moves, a second slider 23 is also provided on its lower surface. The second slider 23 drives the toothed plate 24 to move, placing the hydraulic support into the slot 30. A turntable 32 and a rotating rod 31 are used, with threaded transmission causing the rotating rod 31 to drive the second clamping plate 33 to fix the hydraulic support. Due to the movement of the toothed plate 24... The rotating shaft 26 rotates, engaging with the rotating gear 34. This causes the connecting ring 27 to rotate the connecting rod 28 and the placement plate 29 180°, thus bending the hydraulic support. Meanwhile, the first air pump 15 drives the air rod 16, which in turn drives the arc-shaped connecting plate 17. The arc-shaped connecting plate 17 fits against the outer wall of one side of the hydraulic support, protecting the bending point of the hydraulic support and guiding its bending. Furthermore, the third telescopic rod 20 and the first clamping plate 21 press against one side of the hydraulic support, allowing it to be connected and bent.

[0045] This invention is not limited to the optional embodiments described above, and anyone can derive other various forms of products based on the inspiration of this invention. The specific embodiments described above should not be construed as limiting the scope of protection of this invention; the scope of protection of this invention should be determined by the claims, and the specification can be used to interpret the claims.
