[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1-8 As shown:

[0032] A self-sensing travel positioning waterproof membrane laying trolley hot melt gasket precise positioning device includes an arc-shaped track 1 fixed on the laying trolley, a working slide 2 for movement installed on the arc-shaped track 1, and a travel drive unit 3 for driving the working slide 2 to move along the arc-shaped track 1. The travel drive unit 3 is fixed relative to the working slide 2, and also includes a positioning mechanism 4 that moves with the working slide 2.

[0033] The positioning mechanism 4 includes a rectangular frame structure composed of a retaining bracket 41 and an end plate 42. The two end plates 42 are respectively fixed at both ends of the retaining bracket 41. A positioning part 43 for clamping the hot melt washer is slidably connected in the retaining bracket 41. The positioning part 43 serves as the central axis of the scissor frame 44 to realize the telescopic operation of the scissor frame 44.

[0034] In this scheme, during tunnel construction, there are strict requirements for the distance between adjacent hot melt washers. Currently, it is common to manually measure the distance between hot melt washers using a cross-shaped ruler. However, changes in the angle of the cross-shaped ruler directly affect the accuracy of the measurement. Manually measuring the distance between hot melt washers is not only inefficient, but also makes it difficult to ensure that the horizontally arranged hot melt washers are on the same horizontal line. If the horizontally arranged hot melt washers are not distributed on the same horizontal line, it will increase the difficulty of positioning the subsequent hot melt washers.

[0035] The positioning part 43 can clamp and fix the hot melt gasket. The positioning part 43 is used as the center shaft of the scissors frame 44 to realize the extension and retraction of the scissors frame 44. The scissors frame 44 can drive a plurality of adjacent positioning parts 43 to move synchronously at equal intervals. The positioning part 43 can move horizontally along the retaining bracket 41. When the plurality of positioning parts 43 are close to each other through the scissors frame 44, the worker can install a plurality of hot melt gaskets on the inner side of the positioning part 43 without moving too far, thereby improving the work efficiency and reducing the work intensity. Then, the plurality of positioning parts 43 are driven to move away from each other through the scissors frame 44. Then, the distance between any two adjacent positioning parts 43 is measured. The hot melt gaskets arranged horizontally can be arranged on a horizontal line. The walking driving part 3 can drive the working carriage 2 to move along the arc-shaped track 1. When the working carriage 2 moves, the positioning mechanism 4 can work at different positions.

[0036] In an optional embodiment, the surface of the end plate 42 is fixedly connected with a sensing arm 47 in contact with the geotextile. The sensing arm 47 includes a fixed arm 471 and an extension arm 472. The fixed arm 471 is fixedly connected to the outer surface of the end plate 42. The extension arm 472 is slidably connected to the inner side of the fixed arm 471. The extension arm 472 and the fixed arm 471 are constrained by an elastic member. The extension arm 472 is rotatably connected with a roller 475 at the end close to the geotextile. The rotating shaft of the roller 475 is fixedly connected with the input shaft of an angle sensor 476.

[0037] In the embodiment, the positioning mechanism 4 can determine the interval distribution of a plurality of hot melt gaskets on a horizontal line, and the interval between two adjacent horizontal lines is the distance between the hot melt gaskets in the up-down direction. The interval between the two adjacent horizontal lines can be detected by the sensing arm 47. When the positioning mechanism 4 moves with the working carriage 2, the roller 475 can rotate, and the rotation of the roller 475 can drive the angle sensor 476 to work. The angle sensor 476 can detect the number of rotations and the angle of the roller 475. The interval between the two horizontal lines can be accurately calculated by the number of rotations and the angle of the roller 475. The geotextile is attached to the concrete layer of the tunnel wall. Since the concrete layer is generally sprayed on the tunnel wall, the surface is not smooth. In order to ensure that the roller 475 is always in contact with the geotextile, the fixed arm 471 and the telescopic arm 472 are provided. The telescopic arm 472 is constrained by the elastic member between the fixed arm 471, so that the roller 475 can always be in contact with the geotextile during rotation. Although the surface of the concrete layer is not smooth, the overall distribution of the protrusions or depressions on the surface of the concrete layer is uniform, and the parameters output by the angle sensor 476 are still effective. For example, the data output by the angle sensor 476 is 50 cm, but the actual distance is 48 cm. The distance data of 50 cm obtained by rotating the roller 475 at any position on the geotextile is actually distributed around 48 cm. The actual distance data can be obtained by subtracting the error value from the output data. If it is desired to reduce the difference between the calculated data and the actual data, the diameter of the roller 475 can be increased.

[0038] In an optional embodiment, the inner side of the fixed arm 471 is fixedly connected with a pressure sensor 473, and the telescopic arm 472 is fixedly connected with a retaining spring 474 between the end face on the inner side of the fixed arm 471 and the detection end of the pressure sensor 473.

[0039] In the embodiment, two sensing arms 47 are installed on each end plate 42, and the two sensing arms 47 are in contact with the geotextile, which can better determine that the axis of the positioning part 43 is perpendicular to the tangent of the tunnel surface, and is more conducive to the installation of the hot melt gasket. When the rollers 475 on the two sensing arms 47 are in contact with and support the geotextile, the roller 475 will drive the telescopic arm 472 to move relative to the fixed arm 471. The movement of the telescopic arm 472 will compress the retaining spring 474, so that the elastic force of the retaining spring 474 acts on the pressure sensor 473. When the value of the pressure sensor 473 in one of the sensing arms 47 is the initial value, it means that the sensing arm 47 does not play a supporting role. Preferably, the detection values of the pressure sensors 473 in the two sensing arms 47 are within the normal supporting pressure range and are substantially consistent.

[0040] In an optional embodiment, the positioning part 43 comprises a fixed shell 431 and a sliding shell 432, the inner wall surface of the fixed shell 431 is in sliding connection with the outer end surface of the sliding shell 432, the inner wall surface of the sliding shell 432 is fixedly connected with a limiting ring 433, and the inner side of the limiting ring 433 is fixedly connected with a plurality of elastic clamping pieces 434 for clamping the hot melt gasket.

[0041] In the embodiment, the hot melt gasket is clamped and preliminarily fixed by the elastic clamping pieces 434, and the position of the hot melt gasket can be limited by the limiting ring 433. When it is necessary to fix the hot melt gasket, the end of the nail gun is placed into the inner side of the sliding shell 432, and the end of the steel nail is inserted into the nail hole of the hot melt gasket. The nail gun is continuously pushed to drive the hot melt gasket to move. The hot melt gasket drives the elastic clamping pieces 434 to drive the sliding shell 432 to move against the elastic force of the return spring 435, so that the sliding shell 432 moves towards the geotextile. Since the sliding shell 432 has a certain distance from the geotextile, the sliding of the sliding shell 432 can play a guiding role to avoid the position deviation of the hot melt gasket during movement. After the hot melt gasket is fixed by the nail gun, the nail gun is removed, and then the sliding shell 432 is pulled outwards, so that the sliding shell 432 drives the limiting ring 433 to drive the elastic clamping pieces 434 to move against the friction between the elastic clamping pieces 434 and the hot melt gasket.

[0042] The nail gun should be handheld and the head of the barrel should be cylindrical. After the steel nail is installed, the tip of the steel nail extends a certain distance from the nail gun, for example, a S9700 model nail gun of Saint Eu.

[0043] In an optional embodiment, the outer side of the fixed shell 431 is fixedly connected with a matching plate 436, and one end of the matching plate 436 is provided with a sliding groove 437 matched with the retaining bracket 41.

[0044] In the embodiment, the sliding groove 437 provided on the matching plate 436 can make the fixed shell 431 and the retaining bracket 41 slide stably.

[0045] In an optional embodiment, one end of the fixed shell 431 is provided with an annular groove 438 rotating with the center of the scissor holder 44.

[0046] In the embodiment, the annular groove 438 can realize stable work of the scissor holder 44.

[0047] In an optional embodiment, a return spring 435 is fixedly connected between the outer side of one end of the fixed shell 431 and the folded edge of the end of the sliding shell 432.

[0048] In the embodiment, the elastic force of the reset spring 435 is smaller than the friction force between the elastic clamping piece 434 and the hot melt washer, and the reset spring 435 is arranged to avoid the random sliding of the sliding shell 432 relative to the fixed shell 431, thereby avoiding the friction between the sliding shell 432 and the geotextile during the movement of the positioning mechanism 4.

[0049] In an optional embodiment, the first telescopic mechanism 5 is arranged between the end plate 42 and the working carriage 2, and the first telescopic mechanism 5 is rotationally connected with the end plate 42.

[0050] In the embodiment, the first telescopic mechanism 5 is rotationally connected with the end plate 42 through a rotating support, and the telescopic length of the first telescopic mechanism 5 can be controlled to control the contact pressure between the positioning mechanism 4 and the geotextile, that is, the length of the telescopic extension of the first telescopic mechanism 5 is determined according to the data fed back by the pressure sensor 473, and the first telescopic mechanism 5 can be an electric screw rod or a hydraulic rod.

[0051] In an optional embodiment, the first telescopic mechanism 5 is fixedly or rotationally connected with the working carriage 2.

[0052] In the embodiment, the first telescopic mechanism 5 is rotationally connected with the positioning mechanism 4 and can be telescopically extended, so that the first telescopic mechanism 5 can be fixedly connected with the working carriage 2 through a mounting support, and for special cases, for example, the distance between the paving trolley and the tunnel wall is too small, and the first telescopic mechanism 5 is still too long when it is shortened to the shortest state, the angle between the first telescopic mechanism 5 and the working carriage 2 is adjusted to achieve the adjustment.

[0053] In an optional embodiment, the second telescopic mechanism 6 is arranged between the first telescopic mechanism 5 and the working carriage 2 to adjust the angle of the first telescopic mechanism 5.

[0054] In the embodiment, one end of the second telescopic mechanism 6 is rotationally connected with the working carriage 2 through a rotating support, and the other end of the second telescopic mechanism 6 is rotationally connected with the fixed rod body part of the first telescopic mechanism 5 through a rotating support, and the telescopic extension of the second telescopic mechanism 6 can drive the first telescopic mechanism 5 to adjust the angle.

[0055] It should be further explained that the length adjustment of the shears frame 44 can be manually adjusted by hand, or electric winches 46 can be fixedly connected outside the end plates 42, the electric winches 46 are wound with pull ropes 45, the ends of the pull ropes 45 are fixedly connected with the positioning parts 43, for example, the ends of the pull ropes 45 are fixedly connected with the matching plates 436, when the electric winches 46 arranged at the two end plates 42 work simultaneously and synchronously, the two ends of the shears frame 44 can be synchronously stretched, the center point position of the shears frame 44 remains unchanged, if the electric winches 46 arranged at the two end plates 42 only one works or work asynchronously, the center position of the shears frame 44 will relatively move relative to the support 41 when the shears frame 44 is stretched.

[0056] Finally, it should be noted that the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing detailed description of the present application, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included within the scope of the present application.
