Description

Technical Field

[0001] This utility model belongs to the technical field of H-beam continuous welding centering, and particularly relates to a feeding adjustment mechanism for H-beams on the curved arch line of a tunnel steel arch frame. Background Technology

[0002] Currently, in the follow-up welding and alignment process of the tunnel steel arch frame bending production line, I-beams are fed, clamped, and then welded. However, some I-beams may bend during transportation. The pressure blocks used for clamping are fixed to the alignment components, and these pressure blocks can obstruct the normal feeding of the bent ends of the I-beams during feeding, thus disrupting the continuity of automated production on the tunnel steel arch frame bending production line and affecting production efficiency. Utility Model Content

[0003] To overcome the defects of the prior art, this utility model provides a feeding adjustment mechanism for the curved I-beams of a tunnel steel arch frame, which can avoid the jamming of the curved I-beams during the centering and welding process.

[0004] The objective of this utility model is achieved through the following technical solution: A feeding and adjusting mechanism for I-beams on the curved arch line of a tunnel steel arch frame, comprising: The linear drive mechanism has its fixed end fixedly connected to the centering component, and its output end facing vertically downwards. The first guide block is fixedly connected to the centering component, and the first guide block is provided with a first guide groove along the vertical direction; The second guide block is fixedly connected to the centering component, and a second guide groove is provided on the upper part of the second guide block along the lateral direction; A wedge block is fixedly connected to the lower end of the linear drive mechanism and slidably connected to the first guide groove. The pressure block is slidably connected to the second guide groove, and the upper end face of the pressure block is horizontally attached to the lower end face of the first guide block. The elastic element has a pressure-bearing block and a centering component fixedly connected to its two ends, respectively. The wedge block and the pressure block are respectively provided with a first inclined surface and a second inclined surface for mutual contact.

[0005] The beneficial effects of adopting the above technical solution are as follows: When feeding the H-beam, the linear drive mechanism drives the wedge block to move vertically away from the bearing block. Under the action of the elastic element, the bearing block moves laterally outward so that it no longer obstructs the end of the bent H-beam, thus allowing the H-beam to be fed normally. After the end of the H-beam passes the bearing block, the linear drive mechanism can drive the wedge block to move vertically in the opposite direction. The first inclined surface of the wedge block acts on the second inclined surface of the bearing block to push the bearing block to move laterally inward, so that the bearing block abuts against the side of the H-beam to meet the need for continued welding and pressing of the H-beam after feeding. In summary, this H-beam feeding adjustment mechanism for the tunnel steel arch bending line can avoid the feeding jam of the bent H-beam during the centering and welding process, which is conducive to the continuous production of the tunnel steel arch bending production line and thus helps to improve production efficiency.

[0006] Furthermore, the two sides of the wedge block are respectively attached to the two side walls of the first guide groove.

[0007] The beneficial effect of adopting the above technical solution is that the first guide groove is configured to vertically guide the wedge block.

[0008] Furthermore, the two sides of the pressure block are respectively attached to the two side walls of the second guide groove, and the lower end face of the pressure block is attached to the bottom of the second guide groove.

[0009] The beneficial effects of adopting the above technical solution are as follows: this setting allows the pressure block to slide only inward and outward, which helps to make the movement of the pressure block more stable.

[0010] Furthermore, the linear drive mechanism, the first guide block, and the second guide block can all be detachably connected to the centering assembly.

[0011] The beneficial effects of adopting the above technical solution are: this configuration allows for the replacement or installation of the linear drive mechanism, the first guide block, and the second guide block.

[0012] Furthermore, the output end of the linear drive mechanism is detachably connected to a wedge block.

[0013] The beneficial effect of adopting the above technical solution is that this setting facilitates the replacement or installation of wedge blocks.

[0014] Furthermore, a first inclined surface is provided on the inner side of the wedge block, and a second inclined surface is provided on the outer side of the pressure block.

[0015] Furthermore, the upper end of the first inclined surface is closer to the inside and the lower end is closer to the outside, and the upper end of the second inclined surface is closer to the inside and the lower end is closer to the outside.

[0016] The beneficial effects of adopting the above technical solution are as follows: with this configuration, when the linear drive mechanism drives the wedge block to move downward, the pressure block can move inward; when the linear drive mechanism drives the wedge block to move upward, the pressure block moves outward under the action of the elastic element.

[0017] Furthermore, the tunnel steel arch frame curved arch line I-beam feeding adjustment mechanism includes a first connecting member set on the pressure block and a second connecting member set on the centering assembly. The second connecting member is located outside the first connecting member, and the elastic element is a tension spring.

[0018] The beneficial effects of adopting the above technical solution are as follows: When the linear drive mechanism drives the wedge block to move downward, the pressure block moves inward and the elastic element is stretched; when the linear drive mechanism drives the wedge block to move downward, the elastic element contracts to pull the pressure block to move outward.

[0019] Furthermore, the elastic element is positioned laterally.

[0020] The beneficial effect of adopting the above technical solution is that this setting makes it easier to pull back the pressure block. Furthermore, the second guide block is threaded with a vertical bolt located directly below the wedge block.

[0021] The beneficial effects of adopting the above technical solution are as follows: the vertical bolt can restrict the vertical downward movement of the wedge block; rotating the vertical bolt can adjust the distance between the upper end of the vertical bolt and the lower end of the wedge block to adjust the stroke of the wedge block, thereby adjusting the formation of the bearing block to ensure that the bearing block can press the I-beam.

[0022] The beneficial effects of this utility model are as follows: During H-beam feeding, the linear drive mechanism drives the wedge block to move vertically away from the bearing block. Under the action of the elastic element, the bearing block moves laterally outward so that it no longer obstructs the end of the bent H-beam, allowing the H-beam to feed normally. After the end of the H-beam passes the bearing block, the linear drive mechanism can drive the wedge block to move vertically in the opposite direction. The first inclined surface of the wedge block acts on the second inclined surface of the bearing block to push the bearing block laterally inward, so that the bearing block abuts against the side of the H-beam to meet the need for continued welding and clamping of the H-beam after feeding. In summary, this H-beam feeding adjustment mechanism for the tunnel steel arch bending line can avoid the feeding jam of the bent H-beam during the centering and welding process, which is conducive to continuous production of the tunnel steel arch bending production line and thus improves production efficiency.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] This utility model provides a feeding and adjustment mechanism for I-beams on the curved arch line of a tunnel steel arch frame, such as... Figure 1-4 As shown, it includes: Linear drive mechanism 1, the fixed end of linear drive mechanism 1 is fixedly connected to centering component 11, and the output end of linear drive mechanism 1 faces vertically downward; The first guide block 3 is fixedly connected to the centering component 11, and the first guide block 3 is provided with a first guide groove 301 along the vertical direction; The second guide block 5 is fixedly connected to the centering component 11, and the upper part of the second guide block 5 is provided with a second guide groove 501 in the transverse direction; Wedge block 2 is fixedly connected to the lower end of the linear drive mechanism 1 and slidably connected to the first guide groove 301; The pressure block 4 is slidably connected to the second guide groove 501, and the upper end surface of the pressure block 4 is horizontally attached to the lower end surface of the first guide block 3. The elastic element 9 has a pressure block 4 and a centering component 11 fixedly connected to its two ends, respectively. Among them, the wedge block 2 and the pressure block 4 are respectively provided with a first inclined surface 201 and a second inclined surface 401 for mutual contact.

[0027] Understandably, during the feeding of the I-beam, the linear drive mechanism 1 drives the wedge block 2 to move vertically away from the pressure block 4. Under the action of the elastic element 9, the pressure block 4 moves laterally outward so that it no longer obstructs the end of the bent I-beam, thus allowing the I-beam to be fed normally. After the end of the I-beam passes the pressure block 4, the linear drive mechanism 1 can drive the wedge block 2 to move vertically in the opposite direction. The first inclined surface 201 of the wedge block 2 acts on the second inclined surface 401 of the pressure block 4 to push the pressure block 4 to move laterally inward, so that the pressure block 4 abuts against the side of the I-beam to meet the need for continued welding and pressing of the I-beam after feeding. In summary, this tunnel steel arch bending line I-beam feeding adjustment mechanism can avoid the feeding jam of the bent I-beam during the centering and welding process, which is conducive to the continuous production of the tunnel steel arch bending production line and thus helps to improve production efficiency.

[0028] It should be noted that the linear drive mechanism 1 can be a cylinder, and a speed control valve 7 is provided at the cylinder.

[0029] In one embodiment, the two sides of the wedge block 2 are respectively attached to the two side walls of the first guide groove 301 so that the first guide groove 301 can vertically guide the wedge block 2.

[0030] In one embodiment, the two sides of the pressure block 4 are respectively attached to the two side walls of the second guide groove 501, and the lower end face of the pressure block 4 is attached to the bottom of the second guide groove 501, so that the pressure block 4 can only slide inward and outward, thereby improving the smoothness of the movement of the pressure block 4.

[0031] In one embodiment, the linear drive mechanism 1, the first guide block 3, and the second guide block 5 are all bolted or screwed to the centering assembly 11 for replacement or installation of the linear drive mechanism 1, the first guide block 3, and the second guide block 5.

[0032] In one embodiment, the output end of the linear drive mechanism 1 is bolted or screwed to the wedge block 2 so as to replace or install the wedge block 2.

[0033] In one embodiment, a first inclined surface 201 is provided on the inner side of the wedge block 2, and a second inclined surface 401 is provided on the outer side of the pressure block 4.

[0034] It should be noted that the outer side of the wedge block 2 is attached to one end face of the centering component 11 so that both the first guide groove 301 and this end face of the centering component 11 can provide support for the wedge block 2, thereby reducing the influence of lateral force on the cylinder, which is a linear drive mechanism 1.

[0035] It should also be noted that the centering component 11 and the tunnel steel arch frame curved arch line I-beam feeding adjustment mechanism are both located on one side of the feeding conveying component 12; the side closer to the feeding conveying component 12 is the inner side, and the side farther away from the feeding conveying component 12 is the outer side.

[0036] In one embodiment, the upper end of the first inclined surface 201 is inward and the lower end is outward, and the upper end of the second inclined surface 401 is inward and the lower end is outward; wherein, when the linear drive mechanism 1 drives the wedge block 2 to move downward, the pressure block 4 can move inward; when the linear drive mechanism 1 drives the wedge block 2 to move upward, the pressure block 4 moves outward under the action of the elastic member 9.

[0037] In one embodiment, the tunnel steel arch frame bending arch line I-beam feeding adjustment mechanism includes a first connecting member 8 disposed on the pressure block 4 and a second connecting member 10 disposed on the centering assembly 11. The second connecting member 10 is located outside the first connecting member 8, and the elastic member 9 is a tension spring.

[0038] Understandably, with this configuration, when the linear drive mechanism 1 drives the wedge block 2 to move downward, the pressure block 4 moves inward, and the elastic element 9 is stretched; when the linear drive mechanism 1 drives the wedge block 2 to move downward, the elastic element 9 contracts to pull the pressure block 4 to move outward.

[0039] It should be noted that the first connector 8 and the second connector 10 can be bolts or screws, and the second connector 10 is provided with a hole for connecting the tension spring.

[0040] It should also be noted that a first connecting piece 8 is provided on both sides of the pressure block 4, and two second connecting pieces 10 are provided on the centering component 11. That is, the first connecting piece 8 on each side of the pressure block 4 is connected to a second connecting piece 10 by a tension spring.

[0041] In one embodiment, the elastic element 9 is arranged laterally to make it easier to pull back the bearing block 4.

[0042] In one embodiment, the second guide block 5 is threaded with a vertical bolt 6 located directly below the wedge block 2.

[0043] Understandably, the vertical bolt 6 restricts the vertical downward movement of the wedge block 2; rotating the vertical bolt 6 adjusts the distance between the upper end of the vertical bolt 6 and the lower end of the wedge block 2, thereby adjusting the stroke of the wedge block 2 and adjusting the formation of the bearing block 4 to ensure that the bearing block 4 can press the I-beam. A limit switch can be installed on the vertical bolt 6; after the wedge block 2 moves to a certain distance from the limit switch, it will stop moving and press the I-beam through the bearing block 4.

[0044] The working process of this utility model is as follows: When the I-beam is being fed, the output end of the linear drive mechanism 1 moves vertically upward and drives the wedge block 2 to move vertically upward. The pressure block 4 moves laterally outward under the action of the elastic element 9 so that the pressure block 4 no longer blocks the end of the bent I-beam, thus allowing the I-beam to be fed normally. After the end of the I-beam passes the pressure block 4, the output end of the linear drive mechanism 1 moves vertically downward to drive the wedge block 2 to move vertically downward. The first inclined surface 201 of the wedge block 2 acts on the second inclined surface 401 of the pressure block 4 to push the pressure block 4 to move laterally inward, so that the pressure block 4 abuts against the side of the I-beam to meet the need for continued welding and pressing of the I-beam after feeding.

[0045] In summary, this utility model solves the problem of obstructed feeding of bent I-beam hoppers, improves the automation level of tunnel steel arch frame bending automatic production line, improves the continuity of tunnel steel arch frame bending automatic production line, improves the production efficiency of tunnel steel arch frame bending automatic production line, and makes the production cycle of tunnel steel arch frame production line more stable and reliable, while reducing the production cost of a single I-beam.
