Description

Technical Field

[0001] The utility model relates to the technical field of pier construction, in particular to a grooving device for pier embedded reinforcement construction. Background Technique

[0002] With the increase in traffic density and vehicle load, especially the serious damage to bridges caused by overloading, a considerable number of bridges can no longer meet the use requirements, so it is necessary to reinforce them. Among them, a covering high-strength steel bar embedded reinforcement technology is adopted. This technology is to set longitudinal steel bars on the surface of the embedded structure around the reinforcement structure, fill the grooves with epoxy resin, and enhance the strength by circumferential welding of transverse auxiliary steel bars. Finally, a mortar protective layer and paint are covered. The remarkable technological characteristics of this reinforcement technology are as follows: ① The increased cross-sectional thickness after reinforcement is 1 / 8 of the conventional reinforced concrete reinforcement thickness and less than 1 / 2 of the traditional PCM reinforcement volume; ② The flow resistance of the piers in the river channel after reinforcement basically does not increase; ③ The construction cost is significantly reduced by reducing the use of polymer materials; ④ The reinforcement steel bars are directly embedded on the surface of the existing structure, and the bearing capacity is significantly improved without increasing the concrete cross-section; ④ The increase in weight after reinforcement is very small, and the additional load on the structure foundation and foundation is greatly reduced compared with the traditional reinforcement method.

[0003] When using the above-mentioned embedded reinforcement construction, it is necessary to groove the four sides of the pier to bury the steel bars for reinforcement. However, the existing pier grooving construction requires the erection of scaffolds, and manual scribing and grooving are used, resulting in low grooving efficiency and long construction period.

A bottom plate 73 is jointly installed at the telescopic ends of the two electric telescopic rods 72. A grooving tooth piece 74 is rotatably installed on the bottom plate 73. A driving motor 75 for driving the grooving tooth piece 74 to rotate is installed on one side of the bottom plate 73, and a through groove through which the grooving tooth piece 74 passes is formed on the bottom plate 73. Driving members 6 for driving the support end seats 4 to move along the linear guide rails 3 are installed on the two cross pillow blocks 2.

[0027] Wherein, stepping motors 76 are symmetrically installed on both sides of the suspension frame 71. A transmission gear 77 is fixedly installed on the output shaft of the stepping motor 76. A tooth groove 501 meshing with the transmission gear 77 is formed on the outer side of the support rod 5.

[0028] It should be noted that: during use, the fixed-distance rod 1 and the cross pillow block 2 are fixed on the pier surface through anchor screws. Then, the two support end seats 4 are driven by the driving members 6 on both sides to slide to one side of the cross pillow block 2. Then, the driving motor 75 is started to drive the grooving tooth piece 74 to rotate. Then, the telescopic length of the bottom plate 73 is controlled by the electric telescopic rod 72, so as to control the grooving depth of the grooving tooth piece 74 on the bottom plate 73. During grooving, the stepping motor 76 is synchronously controlled to drive the transmission gear 77 to rotate. The transmission gear 77 meshes with the tooth groove 501, so as to drive the suspension frame 71 to move along the two support rods 5, so as to realize moving grooving. After grooving from bottom to top, move a certain distance horizontally, then groove from top to bottom, and then move in sequence to automatically groove. The grooving is carried out automatically and the grooving depth is controllable.

[0029] Wherein, bolt feet 21 are arranged at both ends of the cross pillow block 2. Threaded through holes 201 are formed in the bolt feet 21. In this way, during installation, the two cross pillow blocks 2 can be anchored on the pier by passing anchor bolts through the threaded through holes 201.

[0030] In the embodiment of the present utility model, please refer to Figure 1 and Figure 2 , the driving member 6 includes a lead screw 61. The lead screw 61 is rotatably installed on the cross pillow block 2, and a transmission block 62 is threadedly installed on the lead screw 61. The transmission block 62 is fixedly connected with the support end seat 4 on the same side by screws.

[0031] It should be noted that when the driving member 6 is in use, the lead screw 61 is driven to rotate by the servo motor 63, so that the lead screw 61 drives the transmission block 62 to drive the support end seat 4 to move along the linear guide rail 3, thereby realizing the adjustment of the lateral displacement.

[0032] In the embodiment of the present invention, please refer to Figure 1 、 Figure 3 and Figure 4 , vertical plates 731 are fixedly installed at the four corners of the upper surface of the bottom plate 73, and sliding sleeves 711 are installed at the four corners of the suspension bracket 71. The sliding sleeves 711 are slidably matched with the corresponding vertical plates 731.

[0033] It should be noted that when the electric telescopic rod 72 pushes the bottom plate 73 away from the suspension bracket 71, the vertical plate 731 slides on the sliding sleeve 711 synchronously, improving the stability of the bottom plate 73 and facilitating the stable grooving of the grooving blade 74.

[0036] It should be noted that when grooving, the micro water pump 82 is started synchronously to spray the water in the water storage tank 81 to the grooving blade 74. In this way, the grooving blade 74 can be cooled and the dust floating can be reduced.

[0037] The working principle of the grooving device for pier embedded reinforcement construction provided by the present invention is as follows:

[0038] When in use, the distance-determining rod 1 and the cross pillow block 2 are fixed on the pier surface by anchor screws. Then, the two support end seats 4 are driven by the driving members 6 on both sides to slide to one side of the cross pillow block 2. Then, the driving motor 75 is started to drive the grooving blade 74 to rotate. Then, the electric telescopic rod 72 is used to control the extension length of the bottom plate 73, thereby controlling the grooving depth of the grooving blade 74 on the bottom plate 73. When grooving, the stepping motor 76 is synchronously controlled to drive the transmission gear 77 to rotate. The transmission gear 77 meshes with the tooth groove 501, thereby driving the suspension bracket 71 to move along the two support rods 5, thereby realizing moving grooving. After grooving from bottom to top, move a certain distance horizontally and then groove from top to bottom, and then move in turn to automatically groove. The grooving is automated, the grooving depth is controllable. When grooving, the micro water pump 82 is started synchronously to spray the water in the water storage tank 81 to the grooving blade 74. In this way, the grooving blade 74 can be cooled and the dust floating can be reduced;

[0039] When the driving member 6 is in use, the lead screw 61 is automatically driven by the servo motor 63, so that the lead screw 61 drives the transmission block 62 to drive the support end seat 4 to move along the linear guide rail 3, thereby realizing the lateral displacement adjustment.
