DETAILED DESCRIPTION
[0023] The following is combined with Figure 1-5 This application is described in further detail.
[0024] Example 1:
[0025] The embodiment of the present application discloses a road embankment slope protection construction work platform, such as Figure 1As shown, the structure comprises a ladder frame 1 and a work platform 2. The ladder frame 1 is located on the slope surface, with its length sloping downward along the slope surface, and the ladder frame 1 and the slope surface are fixed. The work platform 2 is located on one side of the ladder frame 1 and is connected to the ladder frame 1. The ladder frame 1 is used by construction workers to walk up and down, and the work platform 2 is used for operators to place construction materials and tools, or for operators to stand on it to perform construction work.
[0026] like Figure 1 As shown, the frame of the ladder frame 1 is made of square tube steel, and the steps are made of angle steel, which are assembled and fixed by welding. There are two ladder frames 1 and they are arranged horizontally side by side with each other. A space for the work platform 2 is formed between the two ladder frames. The two ladder frames 1 are fixed with handrail guardrails on the side away from each other by welding. There are multiple holes on the ladder frame 1 for the anchor bolts to pass through. The anchor bolts pass through the ladder frame 1 and are driven into the slope of the slope to reinforce the ladder frame 1. The bottom of the work platform 2 is also angle steel. The work platform 2 is placed above the two ladder frames 1. The end of the angle steel below the work platform 2 is overlapped on the top of the step angle steel of the ladder frame 1, and then the overlapped part is welded, so that the work platform 2 and the ladder frame 1 are fixed to each other. In this embodiment, there are two work platforms 2, which are arranged along the length direction of the ladder frame 1. The upper side of the work platform 2 is a hollow platform composed of multiple square steel tubes. After the work platform 2 and the ladder frame 1 are fixed, the surface of the hollow platform is basically a horizontal plane.
[0027] Example 2:
[0028] like Figure 2 and 3 As shown, the difference from Example 1 is that in this embodiment, the work platform 2 and the ladder frame 1 are slidingly connected, and the sliding direction is the length direction of the ladder frame 1. The work platform also includes a control mechanism 3, which is used to control the movement of the work platform 2 along the ladder frame 1 or the fixation of the work platform 2 relative to the ladder frame 1, so that the position of the work platform 2 can be adjusted according to construction needs.
[0029] like Figure 2-4As shown, the control mechanism 3 includes a traction rope 31, a traction roller 32, and a clutch assembly 4. The traction roller 32 is rotatably connected to the ladder frame 1. The axis of the traction roller 32 is perpendicular to the length direction of the ladder frame 1. There are two traction rollers 32, one at the upper and lower ends of the ladder frame 1. A mating channel steel 12 is welded and fixed to the edge of the ladder frame 1 on one side away from the handrail 11. The mating channel steel 12 is formed with a control groove 121 along its own length. The notch of the control groove 121 is lateral. The traction rope 31 is looped around the two traction rollers 32, so the length direction of the traction rope 31 is parallel to the length direction of the ladder frame 1. One strand of the traction rope 31 is located in the control groove 121. A plurality of limiting wheels 321 are coaxially fixedly connected to the traction roller 32. A winding groove 322 is formed between two adjacent limiting wheels 321, and the end of the traction rope 31 is located in the winding groove 322. A motor is also fixedly connected to the top of the ladder frame 1. The output shaft of the motor is coaxially fixedly connected to the traction roller 32. The start and stop of the motor controls the rotation of the traction roller 32, which controls the movement of the traction rope 31. The lower ends of both sides of the work platform 2 are rotatably provided with matching wheels 21. The axis of the matching wheel 21 is parallel to the length direction of the angle steel of the ladder frame 1. When the work platform 2 moves along the ladder frame 1, the matching wheel 21 and the matching channel steel 12 roll and abut to improve the smoothness of the movement of the work platform 2.
[0030] like Figure 3-5 As shown, the clutch assembly 4 is used to selectively fix the work platform 2 relative to the traction rope 31. The clutch assembly 4 includes a fixed block 41, a clutch spring 421, and a first clutch block 42. The fixed block 41 is fixedly connected to the work platform 2, and the first clutch block 42 is slidably connected to the work platform 2, and the sliding direction is laterally approaching or away from the fixed block 41. The traction rope 31 is located between the fixed block 41 and the first clutch block 42. One end of the clutch spring 421 is fixedly connected to the work platform 2, and the other end is fixedly connected to the first clutch block 42. In the natural state, there is a gap between the first clutch block 42 and the fixed block 41. The size of this gap is larger than the thickness of the traction rope 31. That is, at this time, the movement of the traction rope 31 will not affect the fixed block 41, the first clutch block 42, and the work platform 2.
[0031] like Figure 3-5As shown, the clutch assembly 4 also includes an operating rod 44, a clutch worm 45, a clutch worm wheel 46 and a control rod 47. The operating rod 44 and the control rod 47 are both rotatably connected to the work platform 2. The operating rod 44 is located on the table top of the work platform 2 and the rotation axis is horizontal and perpendicular to the length direction of the ladder frame 1. The clutch worm 45, the clutch worm wheel 46 and the control rod 47 are each provided with two and are respectively located at the two ends of the operating rod 44. The clutch worm 45 and the operating rod 44 are coaxially fixedly connected, the clutch worm wheel 46 and the control rod 47 are coaxially fixedly connected, the clutch worm 45 and the clutch worm wheel 46 are meshed, the length direction of the control rod 47 is vertical, and the axis of the control rod 47 is perpendicular to the sliding direction of the first clutch block 42. When the operating rod 44 rotates, the two control rods 47 rotate synchronously. The side wall of the control rod 47 is fixedly connected to the first propulsion block 471. During the rotation of the control rod 47, the first propulsion block 471 selectively abuts against the first clutch block 42. When the first propulsion block 471 abuts against the first clutch block 42, the first clutch block 42 is pushed and moves closer to the fixed block 41, and finally forms a clamping posture with the fixed block 41 to the traction rope 31, and the traction rope 31 and the work platform 2 are relatively fixed through friction.
[0032] like Figure 3-5 As shown, a stop rack 122 is fixedly connected on the ladder frame 1 and in the control groove 121 of the matching channel steel 12, and the length direction of the stop rack 122 is parallel to the length direction of the ladder frame 1; the clutch assembly 4 also includes a stop spring 431, and a second clutch block 43 is also slidably arranged on the work platform 2. The second clutch block 43 is located below the first clutch block 42, and its sliding direction is parallel to the sliding direction of the first clutch block 42. The second clutch block 43 is fixedly connected to the side of the stop rack 122 with a matching rack 432; one end of the stop spring 431 is fixedly connected to the second clutch block 43, and the other end is fixedly connected to the work platform 2. In a natural state, the stop rack 122 and the matching rack 432 do not contact. A second propulsion block 472 is fixedly connected to the side wall of the control rod 47 and below the first propulsion block 471. During the rotation of the control rod 47, the second propulsion block 472 selectively abuts against the side of the second clutch block 43 away from the stop rack 122. When the second propulsion block 472 abuts against the second clutch block 43, the second clutch block 43 is thrust and moves close to the stop rack 122, and finally the mating rack 432 and the stop rack 122 engage with each other. At this time, the work platform 2 cannot move relative to the mating channel steel 12, and the work platform 2 is relatively fixed to the ladder frame 1.
[0033] like Figure 4 and 5As shown, in the axial projection along the control rod 47, the first propulsion block 471 and the second propulsion block 472 have overlapping parts and respective non-overlapping parts, and the area of the overlapping parts accounts for half of the projection area of the first propulsion block 471 and the second propulsion block 472 respectively; that is, there are three situations within the rotation range of the control rod 47: the first propulsion block 471 abuts the first clutch block 42, the first clutch block 42 and the fixed block 41 clamp the traction rope 31, and the second propulsion block 472 does not abut the second clutch block 43, at this time the workbench 2 can move together with the traction rope 31; the first propulsion block 471 abuts the first clutch block 42, the second propulsion block 472 Block 472 abuts the second clutch block 43 to engage the stop rack 122 and the matching rack 432, and the work platform 2 maintains a relatively fixed state with the traction rope 31 and the ladder frame 1 at the same time. At this time, the position of the work platform 2 is fixed and the traction rope 31 cannot move; the first propulsion block 471 does not abut the first clutch block 42, and the second propulsion block 472 abuts the second clutch block 43 to engage the stop rack 122 and the matching rack 432. At this time, the traction rope 31 can move normally, but the work platform 2 maintains a relatively stable positional relationship with the ladder frame 1, so that the fixed state of a single work platform 2 will not be affected by the movement of other work platforms 2.
[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
