[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 refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0028] Depend on Figure 1 and Figure 2As shown, it is a structural schematic diagram of the channel laying auxiliary equipment in this embodiment, including a bracket body 1, a linkage top rod 2 and an extrusion member 3, the top of the bracket body 1 is equipped with a linkage top rod 2 connected to the crane, the bottom of the bracket body 1 is symmetrically equipped with an extrusion member 3, and the two sides of the bracket body 1 are symmetrically equipped with clamping mechanisms 4 for adjusting the angle of the extrusion member 3.

[0029] During use, the corresponding extrusion member 3 is installed according to the specifications and size of the plate to be transported. The bracket body 1 is moved to the top of the plate through the cooperation of the crane and the linkage top rod 2. Then, the angle and position of the extrusion member 3 are changed through the use of the clamping mechanism 4 to make the extrusion member 3 fit the side wall of the plate. This method can stably transport both rectangular plates and V-shaped plates, expands the working range of the equipment itself, and ensures the stability of the equipment during use.

[0030] By the attached Figure 3 and Figure 4 As shown, it is a structural schematic diagram of the clamping mechanism 4 in this embodiment, the clamping mechanism 4 includes a push rod 41, a swing arm 42, a rotating bracket 43 and a mounting side plate 44, the push rod 41 is installed on the surface of the bracket body 1, the rotating bracket 43 is rotatably installed in the bracket body 1, the swing arm 42 is installed on the outside of the rotating bracket 43, the output end of the push rod 41 is connected to the end of the swing arm 42, the mounting side plate 44 is installed on the side of the end of the swing arm 42 away from the push rod 41, the mounting side plate 44 is connected to the extrusion member 3, and the change in the angle of the swing arm 42 is used to drive the extrusion member 3 to clamp the plate.

[0031] During use, the push rod 41 changes its length through its own operation, and the output end of the push rod 41 pushes the end of the swing arm 42, driving the swing arm 42 to rotate with the rotating bracket 43 as the axis. At this time, the installation side plate 44 drives the extrusion part 3 to deflect toward the side close to the plate, so that the installation side plate 44 can be stably fitted with the side wall of the plate, completing the clamping and positioning of the plate, which is convenient for subsequent lifting.

[0032] By the attached Figure 3 As shown, a swing groove for cooperating with the swing arm 42 for swinging is provided inside the bracket body 1, and rotating seats for adjusting the angle according to the length of the push rod 41 are installed at both ends of the push rod 41.

[0033] During use, the swing groove provides sufficient space for the rotation of the swing arm 42, which is convenient for the angle change of the swing arm 42 itself, driving the mounting side plate 44 to deflect. The installation of the rotating seat can assist the push rod 41 in its own stable operation, and flexibly adjust the angle of the push rod 41 itself when the length of the push rod 41 changes.

[0034] By the attached Figure 4As shown, it is a schematic diagram of the structure of the extrusion component 3 in this embodiment, the extrusion component 3 includes an extrusion side plate 31, a splicing plate 32 and an auxiliary component 33, the extrusion side plate 31 is arranged on the side of the clamping mechanism 4, the auxiliary component 33 is symmetrically installed on the side of the extrusion side plate 31, the splicing plate 32 is installed at the end of the extrusion side plate 31, and the splicing plate 32 is installed in the clamping mechanism 4 by bolts.

[0035] During use, the corresponding extruded side plate 31 is selected according to the specifications and size of the plate to be transported, and then the position of the extruded side plate 31 is locked by the cooperation of the splicing plate 32 and the bolts. When the clamping mechanism 4 is running, the angle of the extruded side plate 31 itself changes. At this time, the extruded side plate 31 fits the side wall of the plate, and as the plate squeezes the auxiliary component 33, the auxiliary component 33 is in a locked state, which enhances the friction between the plate and the extruded side plate 31. The trajectory of the extruded side plate 31 itself is an arc shape. When the plate moves to the target position, the extruded side plate 31 will gradually move away from the side wall of the plate, instead of directly releasing the clamping of the plate, to assist the plate in sliding stably into the channel.

[0036] By the attached Figure 5 As shown, it is a schematic diagram of the structure of the auxiliary component 33 in this embodiment, the auxiliary component 33 includes a rolling rubber wheel 331, a movable slider 332 and a first spring 333, the movable slider 332 is symmetrically slidably installed inside the extrusion side plate 31, the rolling rubber wheel 331 is rotatably installed between the movable sliders 332, and the first spring 333 is arranged on the side of the movable slider 332.

[0037] During use, when the extrusion side plate 31 fits against the side wall of the plate, the rolling rubber wheel 331 is squeezed into the extrusion side plate 31 by the outside. At this time, the rolling rubber wheel 331 is in a locked state. As the angle and position of the extrusion side plate 31 change, the rolling rubber wheel 331 will pop out from the extrusion side plate 31 under the elastic force of the first spring 333 itself, and assist the plate to slide into the channel at the lower end.

[0038] By the attached Figure 5 As shown, the extrusion side plate 31 is provided with a rotation groove inside to match the protrusion of the rolling rubber wheel 331, and the rolling rubber wheel 331 is provided with concave grooves equidistantly outside to enhance its own friction.

[0039] During use, the concave groove is provided to enhance the friction of the rolling rubber wheel 331 itself, so that the rolling rubber wheel 331 can assist the plate to slide into the channel stably and accurately, and the rotation groove is provided to facilitate the subsequent rolling of the rolling rubber wheel 331 inside the rotation groove.

[0040] By the attached Figure 6As shown, it is a structural diagram of the calibration mechanism 5 in this embodiment. The auxiliary equipment also includes a calibration mechanism 5, and the calibration mechanism 5 includes a telescopic cylinder 51, a mounting frame 52 and a top bonding plate 53. The telescopic cylinder 51 is installed at the lower end of the bracket body 1, the mounting frame 52 is fixedly installed at the output end of the telescopic cylinder 51, and the top bonding plate 53 is installed in the mounting frame 52.

[0041] When the plate is clamped during use, the top of the plate fits with the top bonding plate 53, squeezing the length of the telescopic tube 51. When the plate is subsequently unloaded, the telescopic tube 51 will push the top bonding plate 53 to make the top bonding plate 53 close to the top of the plate, providing a limit for the plate during the unloading process.

[0042] By the attached Figure 6 As shown, it is a structural schematic diagram of the calibration mechanism 5 in this embodiment, and the calibration mechanism 5 also includes a limit block 54 and a second spring 55. The limit blocks 54 are symmetrically installed at both ends of the top bonding plate 53. The limit blocks 54 are limited by the side of the plate. The second spring 55 is sleeved on the outside of the telescopic tube 51. When the length of the telescopic tube 51 itself shrinks, the second spring 55 is in a force storage state.

[0043] During use, by installing the limit block 54, when the top laminating plate 53 is laminating against the top of the plate, the limit block 54 supports and calibrates the side of the plate, so that the subsequent plate can accurately fall into the channel, and the second spring 55 can assist the telescopic cylinder 51 to quickly reset and push the plate during unloading.

[0044] By the attached Figure 7 As shown, it is a structural schematic diagram of the bracket body 1 in this embodiment, the bracket body 1 includes a first bracket 11, a second bracket 12, a hydraulic push rod 13 and a supporting telescopic rod 14, the first bracket 11 and the second bracket 12 are installed at the bottom end of the linkage top rod 2 through a connecting chain, the hydraulic push rod 13 is installed between the first bracket 11 and the second bracket 12, and the supporting telescopic rod 14 is equidistantly installed between the first bracket 11 and the second bracket 12.

[0045] During use, the hydraulic push rod 13 is used according to the length of the plate to be transported to adjust the distance between the first bracket 11 and the second bracket 12, so that the bottom parts of the first bracket 11 and the second bracket 12 can stably clamp the plate, and the installation of multiple sets of supporting telescopic rods 14 assists the first bracket 11 and the second bracket 12 in supporting, thereby ensuring the stability of the overall bracket body 1 during use.

[0046] A method for using channel laying auxiliary equipment for water conservancy construction comprises the following steps: S1, adjusting, using the hydraulic push rod 13 according to the specifications and shape of the plate to be hoisted, adjusting the distance between the first bracket 11 and the second bracket 12; S2, clamping and transporting, the first bracket 11 and the second bracket 12 are respectively moved to the top of the plate to be transported, and the push rod 41 is running by itself, pushing the swing arm 42 to change its angle, driving the extrusion member 3 to squeeze toward the middle end, and clamping the plate at the middle end, and in the clamping process, the rolling rubber wheel 331 is squeezed by the plate, pushing the moving slider 332 to slide inside the extrusion side plate 31, and the rolling rubber wheel 331 itself is in a locked state; S3, laying, as the lifting equipment drives the support body 1 and the linkage push rod 2 to move as a whole, the plate clamped by the extrusion piece 3 is moved to the top of the channel, and at this time, the push rod 41 itself gradually shrinks in length, so that the two groups of extrusion pieces 3 move to the side away from the plate, so that the plate gradually slides to the bottom, and as the distance between the plate and the extrusion piece 3 increases, the rolling rubber wheel 331 loses external extrusion and quickly resets under the action of the first spring 333. At this time, the rolling rubber wheel 331 is in a rolling state, assisting the plate to move into the channel; S4, calibration. During the movement of the plate, the mounting frame 52 is always in contact with the top of the plate under the action of the second spring 55, locking the vertical lifting of the telescopic cylinder 51, and the limit block 54 limits the movement trajectory of the plate to ensure that the plate moves accurately into the channel; S5, disengagement. With the change of the length of the push rod 41, the extrusion piece 3 completely disengages from both sides of the plate, and the plate slides into the channel under the action of gravity, completing the laying operation in the channel.
