Description

Technical Field

[0001] The present invention belongs to the technical field of keel installation, and particularly relates to a misalignment prevention positioning device for keel installation. Background Art

[0002] In construction projects, keels are usually required to support shapes and fix structures. Keels are widely used in hotels, airport terminals, passenger stations, railway stations, theaters, shopping malls, factories, office buildings, renovation of old buildings, interior decoration settings, ceilings and other places. Keels are the framework and base materials for decoration and are very commonly used. In the formwork support system for arc-shaped plates, a structure of fair-faced formwork, channel beams, shaped keels, and double steel pipes is usually adopted from top to bottom. Since the combined frame has good load-bearing performance, it is widely used. Among them, the shaped keel is installed below the channel beam for shape support and fixing the double steel pipes.

[0003] However, in the existing technology, when installing the shaped keel, rotatable fasteners on both sides are usually used. During the installation process, when the rotation angles of both sides of the fastener are inconsistent, it is easy to cause misalignment in the installation of the shaped keel, resulting in the shaped keel itself not being aligned, affecting the shape of the shaped keel and its load-bearing capacity not reaching the expected effect. Therefore, we propose a misalignment prevention positioning device for keel installation to solve the above problems. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a misalignment prevention positioning device for keel installation, which solves the problem that when installing a shaped keel using traditional fasteners, it is easy to be misaligned, resulting in the shaped keel itself not being aligned, affecting the shape and load-bearing effect of the shaped keel.

[0006] A cross beam;

[0007] Two side clamping plates, slidably connected to the left and right ends of the cross beam;

[0008] A driving device connected to the cross beam, used to drive the two side clamping plates to move towards each other simultaneously to respectively clamp the left and right sides of the keel;

[0009] Two fixture groups respectively arranged on the inner sides of the two side clamping plates. Each fixture group includes two fixtures, and the two fixtures are slidably connected to the upper and lower ends of the corresponding side clamping plate; and

[0010] Two linkage components respectively corresponding to two fixture groups. During the process that the driving device drives the two side clamping plates to move towards each other simultaneously, the two linkage components are driven respectively to drive the corresponding fixture groups, so that the two fixtures in the fixture groups move towards each other to respectively clamp the top and bottom of the keel.

[0011] A further improvement of the anti-displacement positioning device for keel installation according to the present invention lies in that the linkage component includes a linkage member, and the linkage member includes a first plate, a connecting member and a second plate. The first end of the first plate is rotatably connected to the cross beam, and the second end of the first plate is rotatably connected to the upper fixture in the corresponding fixture group, and is used to push the upper fixture to move downward when the corresponding side clamping plate moves towards the other side clamping plate. The first end of the second plate is rotatably connected to the lower fixture in the corresponding fixture group, and the connecting member is hinged between the second end of the first plate and the second end of the second plate, and is used to pull the lower fixture to move upward when the first plate pushes the upper fixture to move downward, so as to realize that the two fixtures respectively clamp the top and bottom of the keel.

[0012] A further improvement of the anti-displacement positioning device for keel installation according to the present invention lies in that the connecting member includes a third plate, a fixing plate, a limiting groove and a limiting slider. The fixing plate is fixed on the side clamping plate. The limiting groove is opened on the side surface of the fixing plate, and the limiting slider is slidably connected in the limiting groove. The first end of the third plate is rotatably connected to the second end of the first plate, and the second end of the third plate is rotatably connected to the limiting slider. The second end of the second plate is rotatably connected to the second end of the third plate, and is used to drive the third plate to push the limiting slider to slide along the limiting groove towards the end away from the side clamping plate when the first plate pushes the upper fixture to move downward, so as to realize pulling the lower fixture to move upward.

[0013] A further improvement of the anti-displacement positioning device for keel installation according to the present invention lies in that the number of linkage members in each linkage component is two, and the two linkage members are respectively arranged on both sides of the corresponding side clamping plate.

[0014] A further improvement of the anti-displacement positioning device for keel installation according to the present invention lies in that each upper fixture includes an upper clamping block slidably connected to the inner side of the corresponding side clamping plate and two upper locking plates respectively fixedly connected to both ends of the upper clamping block. Each lower fixture includes a lower clamping block slidably connected to the inner side of the corresponding side clamping plate and two lower locking plates respectively fixed to both ends of the lower clamping block. The two upper locking plates are respectively rotatably connected to the second ends of the two first plates in the corresponding linkage component, and the two lower locking plates are respectively rotatably connected to the first ends of the two second plates in the corresponding linkage component.

[0015] A further improvement of the anti-displacement positioning device for keel installation in the present invention lies in that the two upper locking plates are respectively arranged corresponding to the two lower locking plates. A first locking fastener is connected to the lower end of the upper locking plate, and a second locking fastener is connected to the upper end of the lower locking plate. When the two jigs in the jig group respectively clamp the top and bottom of the keel, the upper locking plate and the corresponding lower locking plate are locked through the first locking fastener and the second locking fastener.

The two clamping rods are respectively fixed to one side of the two spring groups opposite to each other, so that a cavity for the insertion block to insert to achieve locking is formed between the two clamping rods under the pushing of the two spring groups.

[0017] A further improvement of the anti-displacement positioning device for keel installation in the present invention lies in that the driving device includes a channel, an adjusting rod, a gear, two racks, and two support blocks. The channel is opened at the bottom of the cross beam. The two racks are respectively slidably connected to opposite sides of the channel. The adjusting rod is rotatably connected to the center of the top of the cross beam, and the lower part of the adjusting rod penetrates through the cross beam and extends into the channel. The gear is fixed to the bottom of the adjusting rod, and the gear is located between the two racks and meshes with the two racks. The two support blocks are respectively fixed to the tops of the two side clamping plates, and one end of the two support blocks far away from the corresponding side clamping plates is respectively fixed to the two racks. By turning the adjusting rod to drive the gear to rotate, the two racks are driven to slide in opposite directions, so as to drive the two side clamping plates to move towards each other simultaneously.

[0018] A further improvement of the anti-displacement positioning device for keel installation in the present invention lies in that a turntable is fixed to the upper part of the adjusting rod.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. In the present invention, the side clamping plates at both ends are driven to move towards each other to clamp the left and right sides of the keel. During the process of the side clamping plates at both ends moving towards each other, through the cooperation of structures such as the first plate, the second plate, the third plate, the fixing plate, the limiting groove, and the limiting slider in the corresponding linkage assembly, the two jigs at the upper and lower ends are driven to move towards each other and respectively clamp the top and bottom of the keel, so as to realize the clamping and fixing of the keel, keep the keel at the central position below the cross beam, and avoid the dislocation of the installation position of the keel.

[0021] 2. By providing structures such as insertion blocks, two clamping rods, notches, and two spring groups, during the process of the two clamps at the upper and lower ends moving towards each other, the distance between the insertion block and the two clamping rods gradually decreases. When the two clamps respectively clamp the top and bottom of the keel, the insertion block will insert into the cavity formed between the two clamping rods, and the two spring groups are used to apply elastic forces to the two clamping rods respectively, so that the two clamping rods clamp the insertion block, realizing automatic locking and ensuring the stable positioning of the keel.

[0029] In order to solve the problem that when installing a profiled keel using a traditional fastener, it is easy to be misaligned, resulting in the profiled keel itself not being aligned, affecting the shape and load-bearing effect of the profiled keel, the present invention provides a misalignment prevention and positioning device for keel installation. The following further describes the misalignment prevention and positioning device for keel installation with specific embodiments in combination with the drawings.

[0030] Refer to Figures 1 to 6 As shown, a misalignment prevention and positioning device for keel installation is connected to the lower part of a channel beam. The positioning device includes:

[0031] Cross beam 1;

[0032] Two side clamping plates 2, slidably connected to the left and right ends of the cross beam 1;

[0033] A driving device 3 connected to the cross beam 1, used to drive the two side clamping plates 2 to move towards each other simultaneously, so as to respectively clamp the left and right sides of the keel;

[0034] Two fixture groups 5 respectively arranged on the inner sides of the two side clamping plates 2, each fixture group 5 includes two fixtures, and the two fixtures are slidably connected to the upper and lower ends of the corresponding side clamping plate 2; and

[0035] Two linkage components respectively arranged corresponding to the two fixture groups 5. During the process of the driving device 3 driving the two side clamping plates 2 to move towards each other simultaneously, the two linkage components are driven respectively to drive the corresponding fixture groups 5, so that the two fixtures in the fixture group 5 move towards each other to respectively clamp the top and bottom of the keel.

[0036] Specifically, fixing bolts 6 are fixedly connected to the tops of the left and right ends of the cross beam 1, and the cross beam 1 can be connected to the lower part of the channel beam through the fixing bolts 6;

[0037] Furthermore, a first sliding groove 101 is opened at the bottom of the cross beam 1, and a first slider sliding along the inside of the first sliding groove 101 is fixedly connected to the top of the side clamping plate 2. The side clamping plate 2 is slidably connected to the cross beam 1 through the cooperation of the first slider and the first sliding groove 101;

[0038] By driving the side clamping plates 2 at both ends to move towards each other to clamp the left and right sides of the keel, and during the process of the side clamping plates 2 at both ends moving towards each other, the two fixtures at the upper and lower ends are driven to move towards each other and respectively clamp the top and bottom of the keel through the corresponding linkage components, so as to realize the clamping and fixing of the keel, keep the keel at the central position below the cross beam 1, and avoid the misalignment of the installation position of the keel.

[0039] Among them, refer to Figure 1 and Figure 5As shown in the figure, the linkage assembly includes a linkage member 4. The linkage member 4 includes a first plate 401, a connecting member, and a second plate 406. The first end of the first plate 401 is rotatably connected to the cross beam 1, and the second end of the first plate 401 is rotatably connected to the upper clamp in the corresponding clamp group 5. It is used to push the upper clamp downward when the corresponding side clamp 2 moves towards the other side clamp 2. The first end of the second plate 406 is rotatably connected to the lower clamp in the corresponding clamp group 5. The connecting member is hinged between the second end of the first plate 401 and the second end of the second plate 406, and is used to pull the lower clamp upward when the first plate 401 pushes the upper clamp downward, so as to clamp the two clamps on the top and bottom of the keel respectively;

[0040] The connecting member includes a third plate 402, a fixing plate 403, a limiting groove 404, and a limiting slider 405. The fixing plate 403 is fixed on the side clamp 2. The limiting groove 404 is opened on the side of the fixing plate 403, and the limiting slider 405 is slidably connected in the limiting groove 404. The first end of the third plate 402 is rotatably connected to the second end of the first plate 401, the second end of the third plate 402 is rotatably connected to the limiting slider 405, and the second end of the second plate 406 is rotatably connected to the second end of the third plate 402. It is used to drive the third plate 402 to push the limiting slider 405 to slide along the limiting groove 404 towards the end away from the side clamp 2 when the first plate 401 pushes the upper clamp downward, so as to pull the lower clamp upward.

[0041] By adopting the above design, when the driving device 3 is used to drive the side clamps 2 at both ends to move towards each other, the first plate 401 will push the upper clamp downward. The downward moving upper clamp will push the limiting slider 405 to slide along the limiting groove 404 towards the end away from the side clamp 2 through the third plate 402, so as to pull the lower clamp upward through the second plate 406, realizing the opposite movement of the upper and lower clamps, and thus clamping on the top and bottom of the keel, making the positioning effect better.

[0042] Among them, referring to Figure 1 As shown in the figure, the number of linkage members 4 in each linkage assembly is two, and the two linkage members 4 are respectively arranged on both sides of the corresponding side clamp 2.

[0043] By adopting the above design, the upper and lower clamps can be driven to move more stably.

[0044] Among them, referring to Figures 3 - 5As shown, each upper fixture includes an upper clamping block 501 slidably connected to the inner side of the corresponding side clamping plate 2, and two upper locking plates 503 respectively fixedly connected to both ends of the upper clamping block 501. Each lower fixture includes a lower clamping block 502 slidably connected to the inner side of the corresponding side clamping plate 2, and two lower locking plates 504 respectively fixed to both ends of the lower clamping block 502. The two upper locking plates 503 are respectively rotatably connected to the second ends of the two first plates 401 in the corresponding linkage assembly, and the two lower locking plates 504 are respectively rotatably connected to the first ends of the two second plates 406 in the corresponding linkage assembly.

[0045] Specifically, a second sliding groove 201 is formed in the inner side of the side clamping plate 2. Second sliders that slide along the inside of the second sliding groove 201 are fixedly connected to the sides of the upper clamping block 501 and the lower clamping block 502 facing the side clamping plate 2.

[0046] Furthermore, third sliding grooves 202 are formed on both sides of the side clamping plate 2. The two upper locking plates 503 are respectively located on both sides of the upper end of the side clamping plate 2 and correspond to the third sliding grooves 202 on both sides. The two lower locking plates 504 are respectively located on both sides of the lower end of the side clamping plate 2 and correspond to the third sliding grooves 202 on both sides. Third sliders that slide along the inside of the third sliding groove 202 are fixedly connected to the sides of the two upper locking plates 503 and the two lower locking plates 504 facing the side clamping plate 2.

[0047] By adopting the above design, the movement of the upper clamping block 501 and the lower clamping block 502 can be ensured to be more stable.

[0048] Among them, referring to Figure 6 As shown, the two upper locking plates 503 are arranged corresponding to the two lower locking plates 504. A first locking part is connected to the lower end of the upper locking plate 503, and a second locking part is connected to the upper end of the lower locking plate 504. When the two fixtures in the fixture group 5 respectively clamp the top and bottom of the keel, the upper locking plate 503 and the corresponding lower locking plate 504 are locked through the first locking part and the second locking part.

[0049] The second locking part includes an insertion block fixed to the top of the lower locking plate 504. The first locking part includes two clamping rods, a notch 5031 formed in the lower part of the upper locking plate 503, and two spring groups 5032 respectively fixed to opposite ends of the notch 5031. The two clamping rods are respectively fixed to opposite sides of the two spring groups 5032, so that a cavity for the insertion block to insert to achieve locking is formed between the two clamping rods under the pushing of the two spring groups 5032.

[0050] Specifically, referring to Figure 6As shown, the plug block includes an insertion rod 5041 fixed to the top of the lower locking plate 504 and a fixed platform 5042 fixed to the top of the insertion rod 5041, the fixed platform 5042 and the insertion rod 5041 are combined to form a T-shaped plug block, both sides of the fixed platform 5042 are provided with a first slope, and the two first slopes are in an eight-shaped shape; the clamping rod includes a sliding rod 5033 fixedly connected to the corresponding spring group 5032 and a support platform 5034 fixedly connected to the inner side of the lower end of the sliding rod 5033, the support platforms 5034 on the two sliding rods 5033 are arranged oppositely, and a second slope is provided at the bottom of the support platform 5034, and the second slopes on the two support platforms 5034 are in an eight-shaped shape;

[0051] By adopting the above design, when the clamps at the upper and lower ends move toward each other, the insertion rod 5041 will push against the fixed platform 5042 to support the support platform 5034 at the lower ends of the two sliding rods 5033, and the first slopes at the two ends of the fixed platform will respectively press against the second slopes on the two support platforms 5034. As the fixed platform 5042 moves upward, the sliding rods 5033 at the two ends will gradually be spread apart, and the sliding rods 5033 at the two ends will move toward the two ends respectively, thereby compressing the corresponding spring group 5032 so that the spring group 5032 32 has elastic force. When the upper clamping block 501 and the lower clamping block 502 are clamped at the top and bottom of the keel respectively, the fixing platform 5042 is inserted between the two sliding bars 5033 and is located on the upper part of the two supporting platforms 5034. Then, the spring group 5032 with elastic force at both ends pushes the two sliding bars 5033 to move toward each other, thereby clamping and fixing the fixing platform 5042. The two supporting platforms 5034 can also prevent the fixing platform 5042 from detaching, so as to ensure the stability of the keel positioning.

[0052] The drive device 3 includes a groove 301, an adjusting rod 302, a gear 304, two racks 305 and two support blocks 306. The groove 301 is provided at the bottom of the beam 1. The two racks 305 are slidably connected to the opposite sides of the groove 301 respectively. The adjusting rod 302 is rotatably connected to the center of the top of the beam 1, and the lower part of the adjusting rod 302 passes through the beam 1 and extends to the groove 301. The gear 304 is fixed to the bottom of the adjusting rod 302, and the gear 304 is located between the two racks 305 and meshes with the two racks 305. The two support blocks 306 are respectively fixed to the tops of the two side clamps 2, and the ends of the two support blocks 306 away from the corresponding side clamps 2 are respectively fixedly connected to the two racks 305. The gear 304 is driven to rotate by twisting the adjusting rod 302 to drive the two racks 305 to slide in opposite directions, so as to drive the two side clamps 2 to move toward each other at the same time.

[0053] A rotating disk 303 is fixed on the upper portion of the adjusting rod 302 .

[0054] By adopting the above design, turning the turntable 303 can drive the adjusting rod 302 to rotate, thereby driving the gear 304 to rotate. The rotating gear 304 will drive the two racks 305 to slide towards each other or in the opposite direction along the channel 301, thereby driving the side clamping plates 2 on both sides to slide towards each other or in the opposite direction at the same time. The two side clamping plates 2 sliding towards each other will clamp on the left and right sides of the keel, and can also ensure that the clamping and fixing position of the keel is in the middle area below the cross beam 1, achieving a positioning effect.
