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.

[0033] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0034] Example 1:

[0035] See Figures 1 to 7 A slope section channel maintenance and construction device includes a traction frame 100 and a swing platform 200. The bottom of the traction frame 100 is equipped with multiple traveling wheels 101, and multiple guide wheels 102 are respectively installed on both sides of the traction frame 100. The swing platform 20 is installed at one or both ends of the top of the traction frame 100.

[0036] The swing platform 200 includes a fixed frame 210, a movable frame 220, a first push rod device 250, a support frame 260, and a sliding frame 270. The fixed frame 210 is mounted on the traction frame 100. The upper end of the movable frame 220 is hinged to the upper end of the fixed frame 210. The first push rod device 250 is fixedly mounted on the fixed frame 210. The telescopic end of the first push rod device 250 extends toward the lower end of the fixed frame 210. A crossbar 251 is welded to the telescopic end of the first push rod device 250. Sprockets 252 are rotatably mounted on both ends of the crossbar 251 through bearings. One end of two chains 253 is connected and fixed to the fixed frame 210, and the other end passes upwards around the two sprockets 252 and is connected and fixed to the sliding frame 270 mounted on the fixed frame 210. One end of the support frame 260 is hinged to the sliding frame 270, and the other end is hinged to the movable frame 220.

[0037] By installing guide wheels 102 at both ends of the traction frame 100 and traveling wheels 101 at the bottom of the traction frame 100, the traction frame 100 is pulled by a wire rope winch installed at the top of the inclined section of the channel during operation, allowing the traction frame 100 to move from bottom to top or from top to bottom along the inclined section of the channel. Simultaneously, a swing platform 200 is installed on the traction frame 100. The swing platform 200 can adjust the angle of the movable frame 220 according to the inclination of the inclined section of the channel 1, ensuring that the movable frame 220 is always in a lateral position. This facilitates personnel standing on the movable frame 220 for maintenance and construction, making construction more convenient and safer.

[0038] In this embodiment, see Figure 4 At least two hinge lugs 211 are welded to the upper side of the fixed frame 210 and the lower side of the movable frame 220, respectively. The fixed frame 210 and the hinge lugs 211 on the movable frame 220 are hinged by a pivot.

[0039] See Figure 5 When the telescopic end of the first push rod device 250 extends, the sprocket 252 moves downward, and the chain 253 pulls the sliding frame 270 downward, which in turn... Figure 2 When the sliding frame 270 slides downward, the lower end of the support frame 260 moves downward, thereby supporting the movable frame 220 to swing upward.

[0040] When the telescopic end of the first push rod device 250 retracts, the sprocket 252 moves upward. At this time, the sliding frame 270 moves upward under the gravity of the movable frame 220, the lower end of the support frame 260 moves upward, and the movable frame 220 swings downward.

[0041] In this way, the swing platform 200 can adjust the angle of the movable frame 220 according to the inclination of the ramp section flow channel.

[0042] See Figure 8Because the swing platform 200 adopts this structure, the fixed frame 210 and the movable frame 220 can be folded together, which can meet the maintenance and construction needs of channels with a small slope.

[0043] In this embodiment, the first push rod device 250 can be a hydraulic cylinder or an electric cylinder. The traveling wheel 101 and the guide wheel 102 can be directional casters, and the mounting plate of the directional casters is welded or bolted to the traction frame 100.

[0044] See Figure 6 The sliding frame 270 includes a transverse rod 271, with both ends of the transverse rod 271 hinged to a support frame 260. Support plates 272 are fixedly mounted on both ends of the transverse rod 271 at their lower sides. At least two support columns 273 are fixedly mounted on the opposite sides of the support plates 272, with support wheels 274 rotatably mounted on the support columns 273 via bearings. The fixed frame 210, slidably connected to the sliding frame 270, has sliding grooves 213 at both ends. The sliding grooves 213 on both sides face each other, and the support wheels 274 on the support plates 272 are slidably mounted within the sliding grooves 213 on both sides. This structure allows the sliding frame 270 to slide flexibly on the fixed frame 210.

[0045] In this embodiment, the fixing frame 210 is made of channel steel welded together, and the groove on the channel steel forms the sliding groove 213.

[0046] Further, see Figure 4 A flat plate 230 is welded to the top of the mobile frame 220 for personnel to stand on. When the flat plate 230 is not installed, a plank can be laid on the mobile frame 220. A first guardrail 240 is welded to the top of the flat plate 230 for personnel protection.

[0047] See Figure 1 , 2 An extension plate 280 is welded and fixed to one end of the movable frame 220 that is hinged to the fixed frame 210, so that personnel can enter the movable frame 220 from the ramp section flow channel 1, or enter the ramp section flow channel 1 from the movable frame 220.

[0048] Further, see Figure 1 The upper end of the traction frame 100 is welded and fixed with a passageway platform 300 so that personnel can walk from one side of the movable frame 220 to the other side of the movable frame 220.

[0049] Furthermore, a second guardrail 400 is welded and fixed to the side of the passageway platform 300 facing the movable frame 220, which serves as a safety protection function.

[0050] See Figure 1The traction frame 100 includes a lower crossbeam 110 and an upper crossbeam 120, which are connected to form a frame by multiple connecting rods 130; the lower crossbeam 110 and the upper crossbeam 120 are equipped with a traveling wheel 101 and a guide wheel 102 at both ends.

[0051] Specifically, see Figure 1 , 3 The lower crossbeam 110 has the same structure as the upper crossbeam 120. Both the lower crossbeam 110 and the upper crossbeam 120 include multiple truss units 111. End plates 112 are fixed to both ends of each truss unit 111. The two end plates 112 of adjacent truss units 111 are connected and fixed by multiple bolts. A side plate 113 is fixedly installed on one of the end plates 112. A single ear seat 114 is fixedly connected to the side plate 113. Double ear seats 131 are fixed to both ends of the connecting rod 130. The double ear seats 131 at both ends of the connecting rod 130 are connected to the single ear seats 114 on the upper and lower sides respectively through pins 132. The above structure facilitates the assembly of the traction frame 100.

[0052] Furthermore, the upper and lower ends of the fixing bracket 210 are respectively fixed to the upper crossbeam 120 and the lower crossbeam 110 by multiple U-bolts 212.

[0053] Example 2:

[0054] Based on Example 1, see Figure 7 The fixed frame 210 is mounted on the traction frame 100 via a sliding structure. The fixed frame 210 can slide along the vertical direction of the traction frame 100. A second push rod device 290 is mounted on the traction frame 100, and the telescopic end of the second push rod device 290 is fixedly connected to the fixed frame 210. Through the above structure, the position of the swing platform 200 can be adjusted as a whole, so that the swing platform 200 can have a certain vertical movement space even when the traction frame 100 is stationary.

[0055] In this embodiment, the second push rod device 290 can be a hydraulic cylinder or an electric cylinder. Specifically, the fixed end of the second push rod device 290 can be hinged to the lower crossbeam 110 via a hinged lug pivot, and the telescopic end of the second push rod device 290 is equipped with a fisheye connector, which is hinged to the hinged lug pivot welded to the lower side of the fixed frame 210.

[0056] In this embodiment, the sliding structure includes linear guide rails and sliders. Two linear guide rails are installed parallel to each other at the bottom of the fixed frame 210 by bolts. At least two sliders are installed at the top of the lower crossbeam 110 and the upper crossbeam 120 at the positions corresponding to the linear guide rails by bolts. The sliders slide and guide the linear guide rails in a guiding connection.

[0057] Figure 7 In the middle, when the telescopic end of the second push rod device 290 extends, the swing platform 200 moves upward.

[0058] The working principle or working process of this utility model:

[0059] See Figure 1 When in use, the entire device is placed at the top or bottom of the ramp section flow channel 1. A wire rope winch is installed at the top of the ramp section flow channel 1. The wire rope of the winch is bolted and fixed to the middle of the upper crossbeam 120. The entire device moves within the ramp section flow channel 1 through the winch drive.

[0060] As the entire device moves within the ramp section flow channel 1, the horizontal position of the movable frame 220 is adjusted by controlling the extension and retraction of the first push rod device 250 as the angle of the ramp section flow channel 1 changes.

[0061] When the telescopic end of the first push rod device 250 extends, the sprocket 252 moves downward, and the chain 253 pulls the sliding frame 270 downward, which in turn... Figure 2 When the sliding frame 270 slides downward, the lower end of the support frame 260 moves downward, thereby supporting the movable frame 220 to swing upward.

[0062] When the telescopic end of the first push rod device 250 retracts, the sprocket 252 moves upward. At this time, the sliding frame 270 moves upward under the gravity of the movable frame 220, the lower end of the support frame 260 moves upward, and the movable frame 220 swings downward.

[0063] Personnel can stand on the mobile frame 220 to carry out inspection and construction, which makes the construction more convenient and safer.

[0064] With the traction frame 100 stationary, the height of the swing platform 200 can be adjusted as a whole by controlling the second push rod device 290, so that the swing platform 200 has a certain space for vertical movement.
