[0033] In the description of the present application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. The embodiments of the present application will be described in detail below with reference to the drawings.

[0034] Embodiment 1

[0035] Please refer to Figures 1 to 11 The present application preferably provides a technical solution: a zipper grouting linkage device for concrete repair, comprising: a positioning pin; a corrugated grouting pipe assembly and a zipper repair assembly arranged respectively before and after the positioning pin, the zipper repair assembly comprising zipper suture parts arranged on both sides of a concrete gap, and a traction assembly connected with the zipper suture parts, for closing the zipper suture parts and lifting the corrugated grouting pipe assembly when the traction assembly is working; and a flow sensor and a speed sensor respectively arranged in the corrugated grouting pipe assembly and the traction assembly, and respectively used for collecting grouting flow signals and traction speed signals.

[0036] As shown in Figure 1 、 10 , the corrugated grouting pipe assembly installed before and after the positioning plug and the zip repair assembly can be placed inside and outside the concrete gap respectively. Considering that the existing concrete gap relies on manual positioning and segmented grouting, there is a problem of poor adaptability (grouting and traction are not self-adaptive adjustment, which leads to overflow or hollowing of the slurry). The zip repair assembly provided by the application is composed of zip stitching parts placed on both sides of the concrete gap and traction assemblies connected with the zip stitching parts, and the traction assemblies and the corrugated grouting pipe assemblies are respectively provided with speed sensors and flow sensors to realize the process of adaptive adjustment of grouting and traction. Specifically, in a certain amount of repair gap, the flow sensor collects the grouting flow signal in real time, and the speed sensor collects the traction speed signal. After comparison by the controller (such as PLC, industrial computer or single-chip microcomputer) provided in the device, the output power of the corrugated grouting pipe assembly and the zip repair assembly is dynamically adjusted. If the space in the gap is large and the grouting flow is too fast, the zip traction speed is simultaneously increased. If the space in the gap is reduced or the fast grouting is full and the flow is too slow, the traction speed is reduced. Finally, the self-adaptive adjustment of "grouting amount-traction displacement" is realized to reduce the occurrence of slurry overflow (wide gap) or incomplete grouting (narrow gap).

[0037] In addition, the zip stitching part provided by the application can be placed on both sides of the concrete gap, as shown in Figure 1 、 10 , when the traction assembly moves, it can simultaneously drive the zip stitching part to merge, so as to close the gap and have the tendency to tighten the gap in the middle.

[0038] Embodiment 2

[0039] As another embodiment of the application, the zip stitching part includes an assembly plate 311, a plurality of transmission clamps mounted on the assembly plate 311, and a zip assembly connected between the plurality of transmission clamps. The zip assembly includes two stitching part bodies 312, chain teeth 313 mounted on opposite sides of the two stitching part bodies 312, and a chain head 314 engaged with the two chain teeth 313. One side of the chain head 314 is connected with the traction assembly, and the other side is connected with the bottom end of the corrugated grouting pipe assembly.

[0040] The assembly plate 311 provided in this embodiment is assembled on the positioning plug, and the zip assembly is assembled on the plurality of transmission clamps provided on the assembly plate 311, as shown in Figure 2 、 8 , when the traction assembly drives the chain head 314 engaged with the two chain teeth 313 to move, the two chain teeth 313 and the two stitching part bodies 312 can be gradually closed or separated. The two stitching part bodies 312 can be placed on both sides of the gap, as shown in Figure 1 、10 As shown, when the two suture bodies 312 are combined, the gradually combined two suture bodies 312 can quickly form a blocking structure outside the gap, thereby closing the gap, while the corrugated grouting pipe assembly is synchronously lifted to adjust the grouting position.

[0041] Further, the traction assembly includes a motor 315 fixed near the top side wall of the assembly plate 311, the motor 315 has a take-up reel 316 fixed at the output end, and a traction rope 317 fixed on and around the take-up reel 316, and the end of the traction rope 317 away from the take-up reel 316 is fixed with the chain head 314, as shown in Figure 2 、 8 .

[0042] Embodiment 3

[0043] As another embodiment of the present application, the chain head 314 is further provided with a liquid level sensor at the bottom for sensing the liquid level of the slurry inside the concrete gap.

[0044] As an advanced design of the grouting amount- traction displacement adaptive operation, the chain head 314 is further provided with a liquid level sensor at the bottom, and the liquid level sensor is preferably an ultrasonic liquid level sensor, which is a non-contact liquid level measuring device that measures the liquid level by sending ultrasonic pulses and receiving the reflected signals. The device integrates non-contact switch, controller, and transmitter, and can be applied to slurry and corrosive medium;

[0045] As can be seen from the above, the power provided by the motor 315 can drive the chain head 314 to move, and the movement of the chain head 314 not only realizes the closing or opening of the zipper suture, but also synchronously drives the corrugated grouting pipe assembly to move to adjust the grouting position. At the same time, the speed sensor and the flow sensor respectively arranged in the traction assembly and the corrugated grouting pipe assembly can realize the adaptive adjustment process of grouting and traction;

[0046] In order to improve the application range of the device and expand the application site, the liquid level sensor arranged at the bottom of the chain head 314 can monitor the slurry liquid level in real time. If the set value of the ultrasonic liquid level sensor is in a certain range, as the chain head 314 is driven upward by the traction assembly Figure 1 、 2 , 6, the two suture bodies 312 gradually combine from bottom to top, and the bottom end of the corrugated grouting pipe assembly is synchronously lifted upward. In order to make the slurry fill the gap, the single-chip microcomputer can control the corrugated grouting pipe assembly to adjust the grouting amount in real time according to the signal sent by the liquid level sensor, so that the value detected by the liquid level sensor can be maintained within the set range, and the gap repair process is ensured. This design of repairing the gap according to the actual situation of the gap can expand the application range of the device.

[0047] Embodiment 4

[0048] As other embodiments of the present application, each transmission clamp hand comprises two V-shaped frames 318 fixed on both sides of the assembly plate 311, each V-shaped frame 318 is provided with a transmission frame 319 which can move left and right; and a transmission plate 320 which is provided in the transmission frame 319 and can move forward and backward, and the transmission plate 320 is provided with a hinge element 321 on the opposite side of the V-shaped frame 318, respectively, and the two hinge elements 321 are hinged with a hinge plate 322; further comprising a first through hole respectively opened on the opposite side of the two V-shaped frames 318, each first through hole is provided with an extension column 323, wherein the two extension columns 323 are respectively fixed with the two transmission frames 319 at the opposite ends, and the opposite ends are respectively fixed with transmission wedge blocks 324, and the two transmission wedge blocks 324 are symmetrically distributed and are provided with a center wedge block 334 which can limit sliding; the outer wall of the extension column 323 between each transmission frame 319 and the corresponding assembly plate 311 is further provided with a third spring 325; and the transmission clamp arms are symmetrically arranged on the opposite sides of the two transmission plates 320; further, each transmission clamp arm comprises two racks 337 fixed on one side of the transmission frame 319 close to the extension column 323; and a rotating shaft 326 provided on one side of the transmission plate 320 close to the rack 337, both ends of the rotating shaft 326 are fixed with a gear 336 and a transmission rod 327, wherein the two gears 336 are respectively engaged with the two racks 337; one end of the two transmission rods 327 away from the rotating shaft 326 is fixed with an arc-shaped clamp plate 328, and the opposite sides of the two arc-shaped clamp plates 328 are assembled and connected with the two suture part bodies 312.

[0049] As Figure 8 , 9 shown, the two transmission frames 319 in which the single transmission clamp hand is located are provided inside the two V-shaped frames 318 and can slide left and right inside the two V-shaped frames 318 as Figure 9 shown, the transmission plate 320 provided in each transmission frame 319 is hinged with the hinge plate 322 between the V-shaped frame 318 through the hinge element 321, so that while the transmission frame 319 moves left and right, the transmission plate 320 can move close to (forward) and away from (backward) the suture part body 312;

[0050] Since two transmission frames 319 are fixed on the opposite sides of the telescopic columns 323, which can extend into the corresponding V-shaped frames 318 and are fixed with transmission wedge blocks 324, and the center wedge block 334 is limited to slide between the two transmission wedge blocks 324, when the center wedge block 334 is driven by external force to make the two transmission wedge blocks 324 symmetrically distributed away from or close to each other, at this time, the two transmission frames 319 are away from or close to each other, then the two transmission plates 320 are forward or backward, since the two rotating shafts 326 arranged on the opposite sides of the two transmission plates 320 are connected with the arc-shaped clamping plates 328 through the two transmission rods 327, and the gears 336 fixed on both ends of each rotating shaft 326 are engaged with the rack 337 on the side of the transmission frame 319 close to the transmission wedge block 324, specifically when the two transmission plates 320 are close to the direction of the sewing part body 312 (forward), then Figure 9 the left rotating shaft 326 rotates clockwise to drive the left arc-shaped clamping plate 328 to rotate clockwise, and Figure 9 the right rotating shaft 326 rotates counterclockwise and drives the right arc-shaped clamping plate 328 to rotate counterclockwise, so as to realize the inward buckling process of the two arc-shaped clamping plates 328, cooperate with the positioning bolt, and further realize the process that the two sewing part bodies 312 resist the two sides of the gap and have the tendency of gathering the gap to the middle. This design can be aimed at curved concrete members (such as arc-shaped retaining walls, curved bottom plates), and can overcome the problem of difficult curved surface fitting (rigid clamps cannot adapt to complex curvature) and the like;

[0051] When the two transmission plates 320 are backward, the two sewing part bodies 312, the two arc-shaped clamping plates 328 and the gap are separated.

[0052] Further, the bottom of the two chain teeth 313 is further fixed with an elastic film, wherein the elastic film extends to the chain head 314 direction at both ends and is fixed on both sides of the chain head 314.

[0053] As Figure 2 shown, in order to reduce the influence of concrete on the chain teeth 313 and the chain head 314, when the chain head 314 slides upward between the two chain teeth 313, it can synchronously drive the elastic film to cover the two chain teeth 313 from bottom to top.

[0056] As can be seen from the above, referring to FIGS. Figure 8 、 9 When the two transmission wedges 324 symmetrically distributed are driven to move away from or close to each other by external force, at this time, the two transmission frames 319 are driven to move away from or close to each other, and then the two transmission plates 320 move forward or backward, and in the process of moving forward or backward of the two transmission plates 320, the two suture bodies 312 can abut against both sides of the gap or be separated from the gap.

[0057] In order to realize the above process, that is, to drive the two transmission wedges 324 to move away from or close to each other, as shown in FIGS. Figure 1 、 8 , 9, 11, the electric telescopic rod 331 arranged on the upper part of the assembling plate 311 is provided below with a plurality of driving wedges 332, wherein the driving wedge 332 in the top position is fixed with the telescopic end thereof, the adjacent two driving wedges 332 are connected with the connecting plate 333, and the plurality of driving wedges 332 are in one-to-one transmission contact with the central wedge 334 where the plurality of transmission clamping hands are located, as shown in FIGS.

[0059] As other embodiments of the present application, the slope angle of the wedge surface where the plurality of driving wedges 332 are located gradually increases from bottom to top.

[0060] Considering the problem of inconsistent gap width, the present application takes the case of downward crack of traditional pavement as an example, because the gap gradually narrows from top to bottom, when the corrugated grouting pipe assembly is inserted into the gap, as shown in FIG. Figure 10 , because the slope angle of the wedge surface where the plurality of driving wedges 332 are arranged gradually increases from bottom to top, as shown in FIG.Figure 1 、 11 As shown in FIG. 6, when the electric telescopic rod 331 is telescoped, the upper driving wedge 332 is displaced in the same longitudinal direction, which makes the upper center wedge 334 be displaced more, and the upper two transmission wedges 324 are displaced more away from or close to each other, and the corresponding two suture bodies 312 are more tightly or loosely fitted in the gap. Therefore, this embodiment can realize the process of increasing the tightening force from bottom to top according to the characteristics of the longitudinal diameter of the gap increasing from bottom to top.
