[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] Embodiment 1

[0029] like Figure 1 to Figure 2 As shown, a cap beam support used in the construction process of an elevated bridge described in an embodiment of the present invention includes a support column 1; a connecting plate 11 is fixedly connected to the top of the support column 1; a plurality of groups of No. 1 slide grooves 14 are provided at the top of the connecting plate 11; a connecting rod 12 is slidably connected inside each group of the No. 1 slide grooves 14; a fixing block 13 is provided at the top of the connecting rod 12; the No. 1 slide groove 14 and the connecting rod 12 are connected by a telescopic rod 15; when working, in the cap beam construction stage, two groups of support columns 1 are respectively fixed on both sides of the cap beam, and the connecting rod 12 is driven to move by the thrust of the rising telescopic rod 15, so that the fixing block 13 contacts the side wall of the cap beam for position fixing, and the lifting and lowering of the telescopic rod 15 can drive the fixing block 13 to contact the side wall of the cap beam. When facing different cap beam structures, the different lifting and lowering brought by each group of telescopic rods 15 can make the fixing block 13 accurately contact the cap beam, increase the adaptability of the equipment when in use, maintain the support for the cap beam, and provide strong support for the progress of the project.

[0030] like Figure 2 As shown, the fixed block 13 and the connecting rod 12 are connected by a No. 1 rotating shaft 25; a No. 2 slide groove 2 is provided inside the fixed block 13; a plurality of No. 3 slide grooves 21 are provided at the top of the fixed block 13; the No. 3 slide grooves 21 are connected to the No. 2 slide grooves 2; a fixed plate 22 is fixedly connected to the side wall of the No. 1 rotating shaft 25; a limiting plate 23 is slidably connected inside the No. 2 slide groove 2; a plurality of cleaning plates 24 are fixedly connected to the top of the limiting plate 23 at the position of the No. 3 slide groove 21; when working, when facing cap beams of different angles, the staff uses the cap beam data to fix the fixed The angle of the fixed block 13 is changed on the No. 1 rotating shaft 25 to keep the top of the fixed block 13 in contact with the side wall of the cap beam. At the same time, during the rotation of the fixed block 13, the position of the fixed plate 22 remains unchanged, causing the position of the limit plate 23 to drop. During the dropping process, the end of the cleaning plate 24 scrapes the top of the fixed block 13 to loosen it and reduce the adhesion of large pieces of gravel and impurities. By scraping the top of the fixed block 13 with the cleaning plate 24, it is possible to reduce the adhesion of large pieces of gravel and impurities on the top of the fixed block 13, resulting in a gap when the fixed block 13 contacts the cap beam, causing loose fixation and affecting the accuracy of the cap beam.

[0031] like Figure 3 As shown, a separation block 3 is fixedly connected to the middle of the side wall of the No. 3 slide groove 21; the separation block 3 is in the shape of a triangle that is wide at the top and narrow at the bottom; the separation block 3 is rotatably connected to the No. 1 roller 31 on both sides; the No. 1 roller 31 contacts the side wall of the cleaning plate 24; during operation, after the cap beam support is completed, the fixed block 13 is reset, and after resetting, the limit plate 23 moves upward again under the extrusion of the fixed plate 22, driving the cleaning plate 24 to move in the No. 3 slide groove 21, and the cleaning plate 24 is guided by the inverted triangle setting of the separation block 3 to move to both sides. The rotation of the No. 1 roller 31 can assist the end of the cleaning plate 24 to contact the top of the fixed block 13. The inverted triangle setting of the separation block 3 can increase the accuracy of the cleaning plate 24 during the resetting process, provide support for the subsequent cleaning plate 24 to scrape the top of the fixed block 13, further improve the stability of the cleaning plate 24 during movement, and increase the fault tolerance rate.

[0032] like Figure 3 As shown, the top of the separation block 3 is made of rubber material; a No. 4 slide groove 4 is opened inside the separation block 3; a connecting rope 41 is fixedly connected to the top of the No. 4 slide groove 4; the other end of the connecting rope 41 is fixed to the side wall of the cleaning plate 24; during operation, when the cleaning plate 24 moves downward, the connecting rope 41 will be pulled, causing the top of the separation block 3 to deform and produce a depression, which produces an adsorption effect when it contacts the side wall of the cap beam. The depression at the top of the separation block 3 caused by the movement of the cleaning plate 24 can be used to further fix the cap beam when the top of the subsequent fixing block 13 contacts the cap beam by the adsorption effect produced by the discharge of air, thereby improving stability.

[0033] like Figure 3 As shown, the cleaning plate 24 is provided with multiple groups of elastic ropes 5 on the side wall near the fixed block 13; the end of the elastic rope 5 is fixedly connected to a No. 1 magnet 51; the top of the fixed block 13 is located on both sides of each group of No. 3 slide grooves 21, and a No. 2 magnet 52 is fixedly connected; the No. 1 magnet 51 and the No. 2 magnet 52 are magnetically attracted to each other; when working, during the movement of the cleaning plate 24, the multiple groups of No. 1 magnets 51 are respectively in contact with the No. 2 magnets 52 under the magnetic attraction with the No. 2 magnets 52. As the distance increases, the elastic force of the elastic rope 5 is greater than the magnetic force, and the No. 1 magnet 51 is driven back to the side wall of the cleaning plate 24. By utilizing the magnetic attraction between the No. 1 magnet 51 and the No. 2 magnet 52, the No. 1 magnet 51 and the top of the fixed block 13 can be contacted to produce a collision, thereby causing vibration. At the same time, when the elastic rope 5 recovers the No. 1 magnet 51, the elastic rope 5 will collide with the side wall of the cleaning plate 24, and multiple collisions are used to increase the cleaning effect and reduce the adhesion of large pieces of gravel.

[0034] like Figure 4 As shown, the side wall of the cleaning plate 24 near the fixed block 13 is provided with multiple groups of No. 5 slide grooves 6; the side wall of the No. 5 slide groove 6 is provided with a No. 6 slide groove 61; the No. 6 slide groove 61 is wavy; the elastic rope 5 is fixedly connected to the inner side wall of the No. 6 slide groove 61; the middle part of the elastic rope 5 is fixedly connected with an impact ball 62; during operation, when the No. 1 magnet 51 is attracted and moved by the magnetic force of the No. 2 magnet 52, the elastic rope 5 is pulled and deformed, so that the impact ball 62 moves inside the No. 6 slide groove 61, and the impact is caused by the wavy setting of the No. 6 slide groove 61. By utilizing the wavy opening of the No. 6 slide groove 61, multiple impacts can be produced during the movement of the impact ball 62, bringing a vibration effect, further improving the cleaning of gravel by the cleaning plate 24, and at the same time reducing the adhesion of dust and impurities on the cleaning plate 24 itself, reducing the recovery jam of the cleaning plate 24 caused by the adhesion of dust and impurities, and affecting the fixing effect of the fixed block 13 and the cap beam.

[0035] like Figure 4 As shown, the side wall of the No. 5 slide groove 6 is provided with multiple groups of No. 7 slide grooves 7; the No. 7 slide groove 7 is slidably connected with a collision plate 71; the No. 7 slide groove 7 and the collision plate 71 are connected by a spring; the end of the collision plate 71 is in contact with the No. 1 magnet 51; during operation, when the No. 1 magnet 51 is elastically reset by the elastic rope 5, the No. 1 magnet 51 will enter the No. 5 slide groove 6, contact with the multiple groups of collision plates 71, and produce collisions. At the same time, the collision plate 71 moves multiple times under the action of the spring force. The impact of the No. 1 magnet 51 on the multiple groups of collision plates 71 can further increase the vibration effect of the cleaning plate 24 itself. At the same time, the collision plate 71 continues to move under the action of the spring force, contacts with the surface of the No. 1 magnet 51, and performs secondary vibration, thereby improving the overall cleaning effect of the cleaning plate 24.

[0036] like Figure 3 As shown, the side walls on both sides of the No. 3 slide 21 are fixedly connected with guide plates 8; the middle side wall of the cleaning plate 24 is rotatably connected with the No. 2 roller 81; the No. 2 roller 81 is in contact with the side walls of the guide plate 8; when working, during the movement of the cleaning plate 24, the pair of guide plates 8 installed on the side walls of the No. 3 slide 21 can limit the cleaning plate 24, keep the cleaning plate 24 on a predetermined trajectory for movement, and at the same time, the rotation of the No. 2 roller 81 can assist the movement of the cleaning plate 24. The restriction of the position of the cleaning plate 24 by a pair of guide plates 8 can increase the stability of the cleaning plate 24 during movement, and reduce the jamming problem caused by the offset of the cleaning plate 24. At the same time, the rotation of the No. 2 roller 81 can improve the passability of the cleaning plate 24 and further reduce the jamming.

[0037] like Figure 3 As shown, a pair of guide plates 8 are respectively fixed with a third magnet 9 and a fourth magnet 91 inside; the third magnet 9 and the fourth magnet 91 are magnetically attracted to each other; during operation, during the movement of the cleaning plate 24, the third magnet 9 and the fourth magnet 91 inside the pair of guide plates 8 are further fitted with the side wall of the cleaning plate 24 under the action of magnetic attraction, and the magnetic attraction of the third magnet 9 and the fourth magnet 91 is used to further fix the side wall of the cleaning plate 24, assist the movement of the cleaning plate 24, increase the stability of the cleaning plate 24 during the movement, and reduce the occurrence of deviation.

[0038] Embodiment 2

[0039] like Figure 5 As shown, compared with Example 1, another implementation of the present invention is: the herringbone forked ends of the cleaning plate 24 are each provided with a No. 8 slide groove 102; the side wall of the No. 8 slide groove 102 is rotatably connected to a cam 101; the cam 101 is in contact with the top of the fixed block 13; when working, during the downward movement of the cleaning plate 24, the cam 101 rolls as it contacts the top of the fixed block 13, and a vibration effect is brought about by the rolling of the cam 101. The rotation of the cam 101 can cooperate with the cleaning plate 24 to further clean the gravel particles attached to the top of the fixed block 13, thereby reducing the accumulation of gravel and causing the fixed block 13 and the cap beam to be loosely fixed.

[0040] When working, during the construction stage of the cap beam, the two groups of support columns 1 are fixed on both sides of the cap beam respectively, and the connecting rod 12 is driven to move by the thrust of the rising telescopic rod 15, so that the fixed block 13 is in contact with the side wall of the cap beam for position fixing. When facing cap beams with different angles, the staff uses the cap beam data to change the angle of the fixed block 13 on the No. 1 rotating shaft 25 in advance to keep the top of the fixed block 13 in contact with the side wall of the cap beam. At the same time, during the rotation of the fixed block 13, the position of the fixed plate 22 remains unchanged, so that the position of the limit plate 23 drops, and during the dropping process, the end of the cleaning plate 24 is in contact with the fixed block 13. The top is scraped to remove loose particles to reduce the adhesion of large pieces of gravel and impurities. After the cap beam support is completed, the fixed block 13 is reset. After resetting, the limit plate 23 moves upward again under the extrusion of the fixed plate 22, driving the cleaning plate 24 to move in the No. 3 slide groove 21, and the cleaning plate 24 is guided by the inverted triangle setting of the separation block 3 to move to both sides. The rotation of the No. 1 roller 31 can assist the end of the cleaning plate 24 to contact with the top of the fixed block 13. When the cleaning plate 24 moves downward, the connecting rope 41 will be pulled, driving the top of the separation block 3 to deform and produce a depression, which is in contact with the side wall of the cap beam. When the first magnet 51 is attracted by the magnetic force of the second magnet 52, the elastic rope 5 is pulled to deform, so that the impact ball 62 moves inside the sixth slide groove 61, and the impact is caused by the wave-shaped setting of the sixth slide groove 61. When the first magnet 51 is elastically reset by the elastic rope 5, the impact ball 62 is pulled back to the side wall of the cleaning plate 24. The No. 5 magnet 51 will enter the No. 5 slide groove 6, contact with multiple groups of impact plates 71, and produce collisions. At the same time, the impact plates 71 move multiple times under the action of the spring force. During the movement of the cleaning plate 24, a pair of guide plates 8 installed on the side walls of the No. 3 slide groove 21 can limit the cleaning plate 24 and keep the cleaning plate 24 moving along a predetermined trajectory. At the same time, the rotation of the No. 2 roller 81 can assist the movement of the cleaning plate 24. During the movement of the cleaning plate 24, the No. 3 magnet 9 and the No. 4 magnet 91 inside the pair of guide plates 8 are further fitted with the side walls of the cleaning plate 24 under the action of magnetic attraction.
