[0002] When constructing some river channels, it is necessary to lay waterproofing rolls at the bottom of the riverbed to reduce riverbed leakage. When laying riverbed rolls, wide rolls with a span of 5 to 8 meters are generally used for laying. When laying, rolls are mostly spread by rolling rolls at the bottom of the riverbed manually.

DETAILED DESCRIPTION

[0023] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.

[0024] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0025] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are only connected to form a whole through a connecting structure. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0027] In the present invention, unless otherwise clearly specified and limited, the first feature "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0028] In the present invention, if Figure 1-7 As shown, a riverbed coil paving device is provided, comprising: an unwinding bin, comprising a beam 1, two running wheels 2 arranged at the bottom of the beam 1, the two running wheels 2 are respectively arranged at the two end positions of the beam 1, the unwinding bin also comprises a accommodating chamber capable of accommodating coils, and a driving member for driving the coils to rotate, the accommodating chamber is provided with a discharge trough 3 for the coils to extend out, the accommodating chamber is arranged on the beam 1, one side of the beam 1 forms a front side, and the other side forms a rear side; a paving roller assembly, comprising a pressure roller 4 arranged on the rear side of the beam 1, and a rear bracket 5 connecting the pressure roller 4 and the beam 1; a traction assembly, comprising two capstans 6, the two capstans 6 can be respectively connected to the beam 1 at the position of the running wheels 2, so that the capstan 6 can drive the unwinding bin to move toward the front side of the beam 1 when winding.

[0029] When the paving device of the present invention is used, the entire device is placed at the position to be paved, the coreless coil drum 25 can be placed in the accommodating cavity, and the joint of the coil is led out of the discharge chute 3 and introduced into the rear side of the pressure roller 4. At this time, the coil drum 25 can be driven to rotate by the driving member so that the coil separated from the coil drum 25 can be led out of the discharge chute 3. Under the traction of the two capstans 6, the unwinding bin moves forward, and the coil is spread on the riverbed through the pressure roller 4. During the movement of the paving device, the two running wheels 2 move along the preset theoretical moving tracks respectively to ensure that the coil is spread at the designed position.

[0030] For better explanation of the adjustment method of coil paving process, such as Figures 4 to 7 As shown, the two sides of the coil are divided into side A and side B. When the unwinding bin is offset or tilted, causing the actual paving position of the coil to deviate to side A, the two running wheels 2 also deviate from their theoretical running tracks to side A. During adjustment, the winch 6 corresponding to side B can be stopped for traction, and the position of the running wheel 2 at the corresponding position of side B can be roughly fixed. At this time, the winch 6 corresponding to side A can be used to pull, so that the entire unwinding bin can rotate roughly around the running wheel 2 at the position of side B (as shown in FIG. Figure 4 and Figure 5 The position of the circle with a cross in the middle) is then adjusted so that the A-side running wheel 2 gradually moves to the middle position of its theoretical running track. After the A-side running wheel 2 is corrected, the corresponding winch 6 on the A-side can be stopped, and the paving device can be pulled by the B-side winch 6. At this time, the entire unwinding bin rotates roughly around the A-side running wheel 2 (as shown in the figure). Figure 6 and Figure 7 Move the B-side walking wheel 2 to its corresponding theoretical walking track. After adjustment, the two capstans 6 synchronously pull and drive the unwinding bin to move forward for paving.

[0031] The paving device of the present invention only needs to control the driving of the winch 6. When adjustment is required, it only needs to control the position of the running wheel 2 on one side to stop. Compared with the existing manual paving method that requires multiple people to operate simultaneously, the labor intensity and difficulty of the operator are reduced. Moreover, it is easy to control during adjustment, solving the problem that multiple people cannot coordinate the adjustment process during synchronous operation.

[0032] It should be noted that, in the illustrated embodiment, the winch 6 and the unwinding bin are separate structures, the unwinding bin is provided with a connecting ring 26, and the rope of the winch 6 is connected to the unwinding bin through the connecting ring 26, so that when paving, the winch 6 can be operated by simply placing it on the theoretical path of the running wheel 2. In an alternative embodiment, the winch 6 can also be installed on the unwinding bin, by fixing the connecting ring 26 on the theoretical path of the running wheel 2 (such as fixing it with a ground pile or an expansion bolt).

[0033] In a preferred embodiment, a further optimization arrangement for the present invention is that: Figures 1 to 3 As shown, the paving device also includes: two wireless distance meters 7, which are respectively installed at the positions of the two walking wheels 2 corresponding to the crossbeam 1; and two distance measuring signs 8.

[0034] In this way, when paving, the distance measuring board 8 can be installed at the end point of the theoretical trajectory of the running wheel 2. In this way, during the paving process, the data measured by the distance measuring device can be used to determine whether the two running wheels 2 are moving synchronously, so as to prevent the unwinding bin from tilting significantly.

[0035] In a preferred embodiment, a further optimized setting of the present invention is that the paving device also includes two positioning assemblies, and the two positioning assemblies are respectively arranged at the positions of the two walking wheels 2 of the beam 1, and the positioning assembly includes a liftable lifting part and a base 9 arranged at the bottom of the lifting part.

[0036] In this way, when adjusting, taking the rotation of the travel wheel 2 at the A side position as an example, the base 9 at the A side position is lowered by the lifting part, so that the base 9 is in contact with the riverbed, so as to prevent the A side travel wheel 2 position from being dragged during the traction adjustment of the unwinding bin, thereby facilitating the control of the adjustment accuracy. After the adjustment, the base 9 is raised by the lifting part.

[0037] In a preferred embodiment, the further optimized setting of the present invention is that, as shown in the figure, the lifting part is rotatably connected to the crossbeam 1. By setting the lifting part and the crossbeam 1 to be rotatable, the seat example is adjusted by rotating around the position of the walking wheel 2 on the A side. After the base 9 is lowered to contact the riverbed, the unwinding bin B side is pulled by the winch 6 to rotate the unwinding bin, which can make the A side rotate more flexibly, further facilitating adjustment and control.

[0038] In the illustrated embodiment, with respect to the structure of the present invention, to be more specific, as shown in the figure, the lifting portion is configured as a screw 12 lifting mechanism.

[0039] As shown in the figure, to be more specific, the beam 1 extends a mounting frame 15 at the front side, and the screw 12 lifting mechanism includes an upper mounting plate 14 rotatably mounted on the mounting frame 15, a slide bar 10 and a screw 12 are mounted at the bottom of the upper mounting plate 14, a base 9 is arranged on the lower side of the upper mounting plate 14, and a sliding sleeve 11 slidably matched with the slide bar 10 and a threaded sleeve 13 matched with the screw 12 are provided on the upper side of the base 9. The screw passes through the upper mounting frame 15 and is connected to a handle, so that the base 9 can be controlled to move up and down by rotating the handle, and the rotatable connection of the lifting part is realized by the rotating connection between the upper mounting plate 14 and the mounting frame 15.

[0040] The structural form of the lifting part mentioned above is not intended to be a limitation of the present invention. In an optional embodiment, other forms may be adopted, for example, a lifting part using an electric telescopic rod.

[0041] exist Figure 1 In the embodiment shown, a further optimized configuration of the present invention is that the crossbeam 1 further comprises a control rod 16 connected to the crossbeam 1, and the control rod 16 is arranged at the front side of the base 9. Figure 1 and Figure 2 As shown, the reference rod 16 is placed horizontally on the front side of the base 9, so that during the paving process, the reference rod 16 can be compared with the theoretical path of the running wheel 2 pre-marked on the riverbed (for example, the theoretical path of the running wheel 2 is laid out in advance to form a marking), so as to timely find out whether the unwinding bin is deviated, so as to facilitate adjustment. During the adjustment of the unwinding bin, the reference rod 16 can also be compared with the theoretical path mark to determine whether it is adjusted in place.

[0042] In one specific operation example, a specific operation description is given for an embodiment of the present invention, and the operation includes the following steps: First, determine the riverbed position to be paved, and determine the theoretical path of the running wheel 2 at the paving position, so that the running wheel 2 of the unwinding bin can accurately pave the coil when walking along the theoretical path; Second, such as Figure 3 As shown, a mark 24 is laid out on the bottom of the riverbed according to the theoretical path of the traveling wheel 2. The mark 24 has a certain width in the lateral direction, so that when the mark on the reference rod 16 moves within the corresponding position mark 24, the edge of the coil deviates from the designed size, so that the edge of the coil to be laid can maintain a sufficient overlap width with the edge of the laid coil (the edge of the first coil remains redundant with the boundary of the coil paving area when it deviates within the designed size); The preferred design size is d cm, the width of the layout mark 24 is 2d cm, and the ideal operation mode is that the mark of the control rod 16 corresponds to the middle position of the layout mark 24. When the mark of the control rod 16 reaches the edge of the layout mark 24, the unwinding bin needs to be adjusted; The preferred value of d is 5 cm.

[0043] 3. Install distance measuring signs 8 at key points of the theoretical path; 4. During the movement of the unwinding bin, when the mark of the control rod 16 deviates from the layout mark 24 by one edge position (taking the direction toward the A side as an example), Figure 4 and Figure 5 As shown, the base 9 on the B side is lowered to the riverbed, the traction of the winch 6 on the B side is stopped, and the unwinding bin is rotated around the base 9 on the A side by traction of the winch 6 on the A side until the mark of the reference rod 16 on the A side moves to the middle position of the layout mark 24. Then lower the base 9 on the A side, raise the base 9 on the B side, and stop the traction of the winch 6 on the A side. Figure 6 and Figure 7 As shown, the unwinding bin is rotated by traction of the capstan 6 on the B side until the mark of the control rod 16 on the B side moves to the middle position of the layout mark 24; After adjustment, the data of the two wireless rangefinders 7 are compared to determine the distance difference between the two wireless rangefinders 7 and the rangefinder board 8. When the distance difference is less than or equal to 5 cm, the two winches 6 are synchronously controlled to continue pulling and paving. When the distance difference is greater than 5 cm, the winch 6 on the farther side from the rangefinder board 8 is controlled to pull to reduce the distance difference. After the distance difference is reduced to less than or equal to 5 cm, the position of the mark on the reference rod 16 and the layout mark 24 is determined.

[0044] Regarding the marking of the control rod, it is preferable to provide a marking block on the control rod.

[0045] In the illustrated embodiment, for the structure of the present invention, to be more specific, the driving member includes a conveyor belt 17, the unwinding bin includes a limit shell 18 covering the upper side of the conveyor belt 17, the limit shell 18 and the top surface of the conveyor belt 17 form the accommodating cavity, and one side of the top surface of the conveyor belt forms the discharge trough 3 with the limit shell. Figure 1 As shown, the left side of the conveyor belt 17 is located at the discharge slot 3. When the conveyor belt 17 rotates, the coiled material is conveyed outward from the discharge slot 3. The rotation of the conveyor belt 17 drives the coiled material drum 25 to roll in the accommodating cavity to release the coiled material of the coiled material drum 25 outward.

[0046] exist Figure 1 In the embodiment shown, for the structure of the present invention, more specifically, the top surface of the conveyor belt 17 is set to be inclined, and the limiting shell 18 is formed on the limiting roller 23 abutting against the top surface of the conveyor belt 17. Figure 1 As shown, the top surface of the conveyor belt 17 can be tilted upward as a whole on the left side of the limiting roller 23, so that when the conveyor belt 17 rotates, the coil drum 25 can roll downward when the top surface of the conveyor belt 17 moves to a position close to the discharge slot 3, which can not only promote the release of the coil, but also prevent the coil drum 25 from getting stuck near the discharge slot 3.

[0047] In the illustrated embodiment, for the structure of the present invention, to be more specific, the paving roller assembly also includes a temporary storage bin 19 installed on the crossbeam 1, and a bin opening 20 for the coil to enter is formed at the top of the temporary storage bin 19, and the bottom wall of the bin opening 20 extends to the lower side of the conveyor belt 17 at the position of the discharge trough 3; a lead-out groove is provided at the lower section of the temporary storage bin 19, and the paving roller assembly also includes an upper roller 21 and a lower roller 22 installed in the lead-out groove, and a space for clamping the coil to pass through is formed between the upper roller 21 and the lower roller 22.

[0048] As shown in the figure, by setting up a temporary storage bin 19, the coiled material released from the unwinding bin can be first stored in the temporary storage bin 19. During the movement of the entire device, the pressure roller 4 gradually presses the coiled material on the riverbed and gradually pulls out the coiled material in the temporary storage bin 19, so that the coiled material can be kept at a certain tension from the temporary storage bin 19 to the pressure roller 4, thereby preventing the coiled material from being slackened at the pressure roller 4 position due to excessive coiled material being released from the unwinding bin, thereby further preventing the edge of the coiled material from being misaligned due to the slackening of the coiled material.

[0049] In the illustrated embodiment, for the structure of the present invention, more specifically, the rear bracket 5 is hinged to the cross beam 1. As shown in the figure, the rear bracket 5 is hinged to the cross beam 1 by a transverse shaft, and by such an arrangement, the pressing force of the pressing roller 4 on the coil can be guaranteed.

[0050] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0051] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
