DETAILED DESCRIPTION

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1, reference Figures 1 to 7 , which is the first embodiment of the present invention, provides a conveying device for cable laying, including a placing mechanism 100, and a carrying mechanism 200 arranged on the placing mechanism 100, the carrying mechanism 200 is provided with a supporting mechanism 300, the supporting mechanism 300 is rotatably provided with a limiting mechanism 400, and also includes a clamping mechanism 500 arranged on the carrying mechanism 200; in this embodiment, at least three carrying mechanisms 200 are provided, and each carrying mechanism 200 is provided with a supporting mechanism 300, a limiting mechanism 400 and a clamping mechanism 500.

[0029] Specifically, the supporting mechanism 200 includes a supporting column 201 and a supporting plate 201 a disposed on the supporting column 201 ; in this embodiment, the supporting plate 201 a is fixedly disposed on the outer wall of the supporting column 201 .

[0030] Specifically, the support mechanism 300 includes a bending seat 301 arranged on the supporting column 201, and a support shaft 302 arranged on the bending seat 301, and also includes a first support wheel 303 rotatably arranged on the outer wall of the support shaft 302, and a fixed shaft 304 is fixed inside the bending seat 301; in this embodiment, the first support wheel 303 can rotate outside the support shaft 302, and the fixed shaft 304 is arranged through the bending seat 301.

[0031] Specifically, the limiting mechanism 400 includes a support frame 401 rotatably arranged on the outer wall of the fixed shaft 304, and a second support wheel 402 arranged on the support frame 401, and also includes a positioning groove 403 arranged on the surface of the support frame 401; the clamping mechanism 500 is used to clamp with the positioning groove 403. In this embodiment, the support frame 401 can rotate on the outer wall of the fixed shaft 304, and the second support wheel 402 can rotate on the outer wall of the support frame 401. The outer wall of one end of the support frame 401 close to the fixed shaft 304 is provided with a plurality of evenly distributed positioning grooves 403, and the clamping mechanism 500 can clamp the positioning groove 403 to position the support frame 401.

[0032] Specifically, the clamping mechanism 500 includes a push ring 501 slidably arranged on the outer wall of the supporting column 201, and a plug-in block 502 arranged on the push ring 501, and also includes a spring 503 arranged on the support plate 201a. In this embodiment, the push ring 501 can slide on the outer wall of the supporting column 201, and the plug-in block 502 is used to be plugged into the positioning groove 403 to clamp and position the support frame 401. The elastic force provided by the spring 503 can make the plug-in block 502 have a movement tendency to insert into the positioning groove 403.

[0033] Due to the setting of the bending seat 301, the line between the rotation axis of the support frame 401 and the rotation axis of the first support wheel 303 is inclined. During the rotation of the support frame 401, the second support wheel 402 has two states, that is, it is located on both sides of the first support wheel 303. The setting of the bending seat 301 can make the second support wheel 402 on both sides of the first support wheel 303 have different sizes. Figure 7 , the dotted line portion is the axis movement trajectory of the second support wheel 402, and the second support wheel 402 is located on the left side of the first support wheel 303 at this time. Figure 6 , the dotted line part is the axial motion trajectory of the second support wheel 402. The second support wheel 402 is located on the right side of the first support wheel 303 at this time. Therefore, when it is in the left area, the second support wheel 402 is closer to the first support wheel 303, and when it is in the right area, the second support wheel 402 can move to a position farther away from the first support wheel 303. At the same time, when the second support wheel 402 moves to the left side of the first support wheel 303, the second support wheel 402 can only move downward relative to the first support wheel 303, and when the second support wheel 402 moves to the right side of the first support wheel 303, the second support wheel 402 moves upward first and then moves downward.

[0034] When the cable is laid and the cable is transported into the tunnel, the cable line will be in an arc state, that is, after the cable line is placed on the first support wheel 303, the cable line has an upward area or a downward area. According to the characteristics of the two areas, different limit mechanisms 400 are adjusted. When the cable line is in an upward state, the second support wheel 402 can be controlled to move to the left side of the first support wheel 303. Figure 7 When the cable is between the second support wheel 402 and the first support wheel 303, it can still maintain an upward state, and the cable will not be bent or deformed due to the second support wheel 402 pressing the cable. When the cable is in a downward state, the second support wheel 402 can be controlled to move to the right side of the first support wheel 303. Figure 6When the cable is between the second support wheel 402 and the first support wheel 303, it can still maintain a descending state. Therefore, it is convenient to adjust the position between the first support wheel 303 and the second support wheel 402 according to the state of the cable, so that the shape of the cable is more natural and the resistance during transportation is smaller.

[0035] When transporting the cable, the end of the cable is passed through the second support wheel 402 and the first support wheel 303. The second support wheel 402 and the first support wheel 303 cooperate with each other to prevent the cable from slipping off. By pressing down the push ring 501, the spring 503 can be compressed, and the plug-in block 502 and the positioning groove 403 are separated. At this time, the angle of the support frame 401 can be adjusted, and then the position relationship between the second support wheel 402 and the first support wheel 303 on the limiting mechanism 400 can be controlled. After the adjustment is completed, the plug-in block 502 and the positioning groove 403 are plugged together by the elastic force of the spring 503 to complete the fixation of the support frame 401. In addition, by controlling the distance between the second support wheel 402 and the first support wheel 303, cables of different thicknesses can be installed, which can be suitable for laying cables of different thicknesses.

[0036] Example 2, reference Figure 1 to Figure 7 , which is the second embodiment of the present invention. Different from the previous embodiment, a protrusion 401a is provided on the support frame 401, and a plurality of positioning grooves 403 are provided, and are arranged in a circular array on the protrusion 401a; a locking groove 404 is provided on the surface of the protrusion 401a; an extrusion surface 403a is provided on the inner wall of the positioning groove 403. In this embodiment, the protrusion 401a is provided at one end of the support frame 401 close to the fixed shaft 304, and is provided on a side close to the bending seat 301. The setting of the locking groove 404 can facilitate the insertion of the plug-in block 502. When the plug-in block 502 is inserted into the locking groove 404, the support frame 401 can be fixed. The setting of the extrusion surface 403a can enable the plug-in block 502 to slide out of the positioning groove 403 through the resistance of the extrusion surface 403a.

[0037] Specifically, the surface of the protrusion 401a is provided with a first contact surface 401b, a transition surface 401c and a second contact surface 401d which are connected in sequence. In the present embodiment, the distances between the first contact surface 401b, the transition surface 401c and the second contact surface 401d and the axial center of the fixed shaft 304 gradually increase. When the support frame 401 is rotated, the plug-in block 502 can push the push ring 501 to compress the spring 503 through the guidance of the first contact surface 401b, and then the plug-in block 502 can slide onto the second contact surface 401d through the guidance of the transition surface 401c, so that the plug-in block 502 enters the locking groove 404 or the positioning groove 403.

[0038] Furthermore, the limiting mechanism 400 also includes a disengagement channel 405 disposed on the support frame 401 . In this embodiment, the disengagement channel 405 can separate the support frame 401 from the fixed shaft 304 .

[0039] Preferably, the outer wall of the support frame 401 is rotatably connected to the plug-in frame 406, and the inner wall of the plug-in frame 406 is provided with a parallel surface 406a and an expansion surface 406b. In this embodiment, the inner wall of the plug-in frame 406 and the outer wall of the support shaft 302 are slidingly connected, and the setting of the expansion surface 406b can facilitate the insertion of the plug-in frame 406 into the outer wall of the support shaft 302.

[0040] The rest of the structure is the same as that of Example 1.

[0041] When in use, first place the cable on the first support wheel 303, connect the support frame 401 and the fixed shaft 304 through the disengagement channel 405, control the support frame 401 so that the fixed shaft 304 slides to the position where the protrusion 401a is located, align the opening of the plug-in frame 406 with the outer wall of the support shaft 302, and then rotate the support frame 401, the first contact surface 401b will contact the plug-in block 502, so that the spring 503 is compressed, and the transition surface 401c contacts the plug-in block 502, so that the spring 503 is further compressed until the second contact surface 401d contacts the plug-in block 502, the spring 503 continues to be compressed, and when the positioning groove 403 and the plug-in block 502 are aligned, the plug-in block 502 is inserted into the positioning groove 403, and the support frame 401 continues to rotate. Due to the setting of the extrusion surface 403a, the support frame 401 can rotate in one direction, so that the positions of the first support wheel 303 and the second support wheel 402 are adjusted. The setting of the plug-in frame 406 can prevent the cable from sliding due to tilting. Since the support frame 401 can only rotate in one direction, when the force is generated on the second support wheel 402 during the transportation of the cable, self-locking can be achieved to improve the limiting effect.

[0042] Furthermore, since the limiting mechanism 400 can be disassembled and installed between the supporting mechanism 300, it is convenient to detach the cable from the device after the cable is installed, or to install the cable on the device. At the same time, the unidirectional rotation direction of the supporting frame 401 can be controlled according to the installation orientation, and the unidirectional rotation direction of the supporting frame 401 can be selected according to the shape of the cable during transportation.

[0043] Example 3, reference Figure 1 to Figure 7 , which is the third embodiment of the present invention. Different from the previous embodiment, the placement mechanism 100 includes a support frame 101 and support feet 103 arranged on the support frame 101; in this embodiment, support feet 103 are fixedly provided at the four corners of the bottom of the support frame 101.

[0044] Furthermore, the supporting mechanism 200 also includes a supporting plate 202 arranged at the end of the supporting column 201, and a sliding frame 203 arranged on the supporting plate 202; the inner wall of the sliding frame 203 is slidably connected to the outer wall of the support frame 101. In this embodiment, the sliding frames 203 are fixedly provided at both ends of the supporting plate 202.

[0045] Specifically, it also includes a locking mechanism 600 arranged on the supporting mechanism 200, the locking mechanism 600 includes a connecting arm 601 arranged on the push ring 501, and a sliding column 602 arranged on the connecting arm 601, and also includes a connecting rod 603 rotatably arranged on the sliding column 602, the end of the connecting rod 603 is rotatably provided with a push rod 604, and the end of the push rod 604 is fixedly provided with an insert block 605. In this embodiment, the connecting arm 601 and the push ring 501 are fixedly connected, and when the push ring 501 slides down, it can drive the connecting arm 601 to descend. The descent of the connecting arm 601 will cause the sliding column 602 to slide in the supporting column 201, and the descent of the sliding column 602 will cause the connecting rod 603 to push the push rod 604, and then push the insert block 605.

[0046] Furthermore, a positioning hole 102 is provided on the surface of the support frame 101 ; in this embodiment, the sizes of the positioning hole 102 and the insert block 605 match each other, and the insert block 605 can be inserted into the positioning hole 102 .

[0047] Specifically, a limiting sleeve 202 a is provided on the bearing plate 202 , and the inner wall of the limiting sleeve 202 a is slidably connected to the outer wall of the push rod 604 .

[0048] Specifically, an upper slide groove 201 b and a lower slide groove 201 c are provided on the surface of the bearing column 201 ; the inner wall of the upper slide groove 201 b is slidably connected to the outer wall of the connecting arm 601 .

[0049] The rest of the structure is the same as that of Example 2.

[0050] During use, when the limiting mechanism 400 is not installed, under the elastic force of the spring 503, the push ring 501 can pull the sliding column 602, so that the plug block 605 and the positioning hole 102 are in a separated state. At this time, the supporting position of the cable can be adjusted by sliding the supporting mechanism 200, so that the cable can form arcs of different sizes when it is installed. When installing the limiting mechanism 400, due to the downward movement of the push ring 501, the plug block 605 will be inserted into the positioning hole 102, thereby completing the fixation of the supporting mechanism 200, so that the supporting mechanism 200 can remain stable during cable transportation.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
