Description

Technical Field

[0001] The utility model relates to the technical field of hot rolling of steel coils, in particular to a self-holding side guide structure. Background Art

[0002] During the production of steel coils, the steel coils usually need to be cooled on the transmission rollers and finally reeled up by the coiler.

[0003] In order to enable the steel coil to accurately move to the coiler for winding, side guide structures are usually set on both sides of the steel coil travel path to guide and limit the movement of the steel coil to align it with the center line of rolling, thereby avoiding the occurrence of steel coil shape defects.

[0004] Since the side guide structure will produce friction with the steel coil and will be worn, it needs to be replaced relatively frequently. The side guide replacement is usually completed by the cooperation of the crane. To ensure smooth loading and unloading, the positioning pins and pin holes are designed with a large gap, resulting in poor accuracy after assembly and cannot well ensure the centering and winding of the steel coil.

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a self-tightening side guide structure, which can eliminate the gap between the pin hole and the positioning pin without affecting smooth assembly.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A self-tightening side guide structure comprises: a side guide strip plate provided with a pin hole, wherein the peripheral wall of the pin hole is surrounded by a plurality of embedding grooves; a locking block, which is arranged around a plurality of embedding grooves corresponding to the embedding grooves and has a loose state and a locked state, wherein the locking block in the locked state is higher than the locking block in the loose state; in the locked state, the locking block partially protrudes out of the peripheral wall of the pin hole to clamp the positioning pin embedded in the pin hole; the locking block is movably installed in the embedding groove along a first preset direction to move between the loose state and the locked state, wherein the first preset direction is set to be inclined from bottom to top toward the center of the pin hole; a supporting structure is used to support the locking block in the loose state.

[0008] Furthermore, a bearing surface is provided at the bottom of the side guide strip, and in a loosened state, the bottom of the locking block protrudes from the bearing surface; in a locked state, the bottom surface of the locking block is flush with the bearing surface.

[0009] Furthermore, the bearing surface is provided with a countersunk groove corresponding to the pin hole, the supporting structure is a limiting ring embedded in the countersunk groove, and the center of the limiting ring is provided with a center hole with a diameter greater than or equal to the pin hole.

[0010] Furthermore, a supporting surface and a protrusion are provided at the bottom of the locking block, and the bottom of the protrusion is lower than the supporting surface; when in the loosened state, the supporting surface abuts against the upper end surface of the limiting ring, and the center hole is provided with an avoidance gap for the protrusion to pass through.

[0011] Furthermore, the limiting ring and the top wall of the countersunk groove are provided with corresponding holes for connection and fixation via fasteners.

[0012] Furthermore, a guide groove with a width greater than that of the embedding groove is provided on the side of the embedding groove away from the center of the pin hole, and a slider embedded in the guide groove is provided on the side of the locking block away from the center of the pin hole, and the slider is adapted to the guide groove and can slide along the guide groove; the guide groove extends along a first preset direction.

[0013] Furthermore, a pressure cover is installed at the upper end of the pin hole, and a compression spring is provided between the locking block and the pressure cover to apply a downward force to the locking block.

[0017] The utility model has the following beneficial effects:

[0018] During assembly, the side guide plate is lowered after the pin hole is aligned with the locating pin. At this time, there is a gap, which is conducive to smooth assembly. When the locating pin is partially inserted into the pin hole and supported and pushed by the bottom cantilever seat, the locking block moves upward and tilts toward the center of the pin hole, thereby locking the locating pin, eliminating the assembly gap, improving the installation accuracy and the guidance accuracy of the steel coil, and does not affect the smooth assembly when the assembly and alignment begin.

[0039] Please refer to Figure 1 and Figure 2 A self-holding side guide structure in a preferred embodiment of the present invention includes a side guide strip 100, a locking block 200 and a supporting structure.

[0040] The side guide strip plate 100 is provided with a pin hole 120, which vertically penetrates the side guide strip plate 100, and a plurality of embedded grooves 130 are arranged around the peripheral wall of the pin hole 120; the diameter of the pin hole 120 is larger than the positioning pin 101; a plurality of locking blocks 200 are arranged around the corresponding embedded grooves 130, and the locking block 200 has a loose state and a locked state, and the loose state is as follows: Figure 7 As shown, the locking state is as follows Figure 8 The locking block 200 in the locked state is higher than the locking block 200 in the released state; in the locked state, the locking block 200 partially protrudes from the peripheral wall of the pin hole 120 to clamp the positioning pin 101 embedded in the pin hole 120; the locking block 200 is movably installed in the embedding groove 130 along a first preset direction to move between the released state and the locked state, and the first preset direction is set to be inclined from bottom to top toward the center of the pin hole 120; the supporting structure is used to support the locking block 200 in the released state.

[0041] The utility model provides a self-tightening side guide structure. During assembly, the side guide strip 100 is lowered after the pin hole 120 is aligned with the positioning pin 101. At this time, there is a gap, which is conducive to smooth assembly. When the positioning pin 101 is partially inserted into the pin hole 120 and supported and pushed by the bottom cantilever seat 102, the locking block 200 moves upward and tilts toward the center of the pin hole 120, thereby locking the positioning pin 101, eliminating the assembly gap, improving the installation accuracy and the guiding accuracy of the steel coil, and does not affect the smooth assembly when the assembly alignment begins. The supporting structure supports the locking block 200 in a loose state to prevent it from falling.

[0042] Reference Figure 5 and Figure 6 In some embodiments of the utility model, a bearing surface 110 is provided at the bottom of the side guide strip 100. When in the loose state, the bottom of the locking block 200 protrudes from the bearing surface 110; when in the locked state, the bottom surface of the locking block 200 is flush with the bearing surface 110. The bearing surface 110 is used to contact the upper surface of the cantilever seat 102 to achieve gravity load transmission. Since the bottom of the locking block 200 protrudes from the bearing surface 110 in the loose state, when the bearing surface 110 contacts the upper surface of the cantilever seat 102, the cantilever seat 102 will push the locking block 200 upward to move upward to the locked state, thereby locking the positioning pin 101. When hoisting, the locking block 200 is separated from the locking block 200, and the locking block 200 loses the upward force, which will release the positioning pin 101, so that the side guide strip 100 can be smoothly removed upward.

[0043] Reference Figure 5 and Figure 6 In some embodiments of the utility model, a countersunk groove 140 is provided on the bearing surface 110 corresponding to the pin hole 120, and the supporting structure is a limiting ring 300 embedded in the countersunk groove 140. A center hole 310 with a diameter greater than or equal to the pin hole 120 is provided at the center of the limiting ring 300. The countersunk groove 140 is used to prevent the limiting ring 300 from protruding from the bearing surface 110, so that the bearing surface 110 will contact the upper surface of the cantilever seat 102, thereby triggering the locking block 200 to move upward, ensuring that the locking block 200 locks the positioning pin 101.

[0044] Reference Figures 6 to 8 In a further embodiment of the utility model, a supporting surface 210 and a protrusion 220 are provided at the bottom of the locking block 200, and the bottom of the protrusion 220 is lower than the supporting surface 210; when in the released state, the supporting surface 210 abuts against the upper end surface of the limiting ring 300, thereby supporting the locking block 200 in the released state and preventing the locking block 200 from falling, and limiting the downward movable stroke of the locking block 200. The center hole 310 is provided with an avoidance notch 320 for the protrusion 220 to pass through, thereby facilitating the protrusion 220 to pass through the avoidance notch 320 and protrude from the supporting surface 210 so as to be pushed by the cantilever seat 102.

[0045] In a specific embodiment of the present invention, corresponding holes are provided on the top wall of the limiting ring 300 and the countersunk groove 140 to be connected and fixed by fasteners, and the fasteners may be screws, so as to realize detachable fixed installation of the limiting ring 300 .

[0046] Reference Figure 6In some embodiments of the present invention, a guide groove 131 having a width greater than that of the embedding groove 130 is provided on one side of the embedding groove 130 away from the center of the pin hole 120, that is, the embedding groove 130 and the guide groove 131 form a T-shaped groove, and a slider 230 embedded in the guide groove 131 is provided on one side of the locking block 200 away from the center of the pin hole 120. The slider 230 is adapted to the guide groove 131 and can slide along the guide groove 131, thereby realizing sliding guidance and limiting, so that the movement of the locking block 200 is more stable. The guide groove 131 extends along the first preset direction, that is, the guide groove 131 is inclined from small to upper toward the center of the pin hole 120. Specifically, the supporting surface 210 is the bottom surface of the slider 230, so that the surface of the slider 230 is directly used as the supporting surface 210, simplifying the structure, so that the slider 230 has multiple functions.

[0047] Reference Figure 3 , Figure 4 and Figure 7 In some embodiments of the utility model, a pressure cover 400 is installed at the upper end of the pin hole 120, and the pressure cover 400 is annular as a whole. A compression spring 500 is provided between the locking block 200 and the pressure cover 400 to apply a downward force to the locking block 200, so that when the bearing surface 110 is separated from the upper surface of the cantilever seat 102, the locking block 200 will move downward under the action of the compression spring 500 and separate from the positioning pin 101, forming a gap, which facilitates the smooth removal of the side guide plate 100.

[0048] Reference Figure 4 In some embodiments of the present invention, a mounting groove 150 is provided at the upper end of the embedding groove 130, and the compression spring 500 is installed in the mounting groove 150, thereby limiting the compression spring 500 and ensuring that the compression spring 500 is stably installed.

[0049] Reference Figure 4 In a further embodiment of the utility model, a mounting groove 150 is provided at the upper end of the embedding groove 130, an embedded groove 160 is provided at the upper end of the pin hole 120, the pressure cover 400 is embedded in the embedded groove 160, and corresponding holes are provided on the bottom wall of the pressure cover 400 and the embedded groove 160 to be connected and fixed by fasteners, thereby facilitating the positioning and installation of the pressure cover 400 and facilitating the subsequent disassembly and replacement of parts.

[0050] Reference Figure 1 In some embodiments of the utility model, a guide portion 170 for guiding the steel coil to enter is provided at one end of the side guide plate 100, and the guide portion 170 expands and extends outward. The side guide plates 100 are usually provided with two and are symmetrically distributed on both sides of the traveling direction of the steel coil. The guide portions 170 on the two side guide plates 100 are flared to facilitate the introduction of the steel coil.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
