DETAILED DESCRIPTION
[0026] The utility model will be further explained in detail below in combination with the drawings.
[0027] Embodiment:
[0028] Reference Figure 1 - Figure 6 The utility model discloses a CIP cleaning system's safety protection device with a crawling ladder, including the crawling ladder and safety harness 3 that the vertical rod 1 of two and several cross rods 2 are common to constitute, and the harness top end of safety harness 3 is provided with the harness hanging ring, and the back side of safety harness 3 is provided with the back hanging ring, and its characterized in that, the side wall of two vertical rods 1 is common to be provided with several even distribution's arc-shaped blocking ring 4, and the inside of arc-shaped blocking ring 4 is common to be provided with sliding rail 5, and the inside of sliding rail 5 is provided with first anti-falling structure 6.
[0029] Both vertical rods 1 have sliding grooves 7 inside, and a second anti-fall structure 8 is installed inside the sliding grooves 7;
[0030] The second fall protection structure 8 includes a sliding block 801 and a locking plate 802. The sliding block 801 is inserted into the sliding groove 7 and is slidably connected to the sliding groove 7. A rotating groove 803 is provided at one end of the sliding block 801 facing the sliding groove 7. A bent rod 804 is rotatably connected to the top of the rotating groove 803. A connecting ring 805 is provided at the bottom of the bent rod 804. The connecting ring 805 is connected to the shoulder strap loop through a protective steel cable. A locking shaft 806 is provided at the position above the connecting ring 805 on the bent rod 804.
[0031] The locking plate 802 includes a mounting plate 8021. Two mounting plates 8021 are provided and are fixedly installed on both sides of the opening of the sliding groove 7. Several locking blocks 8022 are provided on the opposite side of the two mounting plates 8021, and the spacing between two adjacent locking blocks 8022 is equal.
[0032] In this embodiment, an arc-shaped retaining ring 4 forms a protective ring on the outer perimeter of the ladder to prevent workers from falling. The first anti-fall structure 6 prevents workers from falling while climbing upwards, and the second anti-fall structure 8 prevents workers from falling due to missteps while moving downwards.
[0033] like Figure 5 As shown, this is the normal state of a worker crawling. At this time, there is a large gap between the worker's torso and the ladder. The connecting ring 805 is connected to the safety harness 3 via a protective steel cable. Figure 5 As shown, at this time, the bending rod is lifted upward by the tension of the protective steel cable. At this time, the locking shaft 806 cannot be inserted between the two locking blocks 8022, so that the sliding block 801 can slide up and down freely inside the sliding groove 7.
[0034] When a worker falls, due to the influence of gravity, the worker will descend and gradually approach the ladder. At this time, the gap between the worker's torso and the ladder is small, so the bending rod 804 will droop under the influence of gravity, and the locking shaft 806 will be embedded between the two locking blocks 8022. At this time, the sliding block 801 is affected by the locking shaft 806 and cannot slide downward, thereby achieving the purpose of protecting the worker and preventing a fall.
[0035] In a further preferred embodiment of this utility model, such as Figures 1-6 As shown, the locking block 8022 is fixedly connected to the mounting plate 8021. The top of the locking block 8022 is provided with an anti-slip rubber pad, and the bottom of the locking block 8022 is provided with a guide arc angle 8023. The distance between two adjacent locking blocks 8022 is equal to the diameter of the locking shaft 806.
[0036] In the embodiment, when the bending rod 804 is vertically under the influence of gravity, the card-in shaft 806 can be embedded between the two locking blocks 8022 through the guidance of the guide arc corner 8023, the bending rod 804 and the sliding block 801 are fixed, and the purpose of stopping the worker from falling is achieved.
[0037] In further preferable embodiments of the utility model, as shown in the figure, Figures 1-6 The first anti-falling structure 6 includes an anti-falling sliding block 601 and an anti-falling toothed plate 602.
[0038] The anti-falling toothed plate 602 is provided with two plates and is arranged on both sides of the inside of the sliding rail 5.
[0039] In the embodiment, the oblique supporting plate is always protruding from the sliding through slot 603 and is embedded with the anti-falling toothed plate 602 through the arrangement of the spring inside the sliding through slot 603, as shown in the figure, Figure 2 At this time, the anti-falling sliding block 601 can only move upward, and the anti-falling sliding block 601 is dragged upward during the upward movement of the worker.
[0040] In further preferable embodiments of the utility model, as shown in the figure, Figures 1-6 Both ends of the sliding rail 5 are open.
[0041] In the embodiment, since the sliding rail 5 is open, the anti-falling sliding block 601 is inserted into the inside of the sliding rail 5 from the bottom end of the sliding rail 5 when the worker climbs upward, is moved upward, and is extracted when reaching the top.
[0042] In further preferable embodiments of the utility model, as shown in the figure, Figures 1-6 The top end of the anti-falling sliding block 601 is provided with a protruding shaft 605, the side wall of the protruding shaft 605 is provided with a protruding hanging ring 606, and the protruding hanging ring 606 is connected with the back hanging ring through the safety belt.
[0043] In the embodiment, the protruding shaft is arranged to install the protruding hanging ring 606 and connect the safety belt and the safety harness 3 through the protruding hanging ring 606.
[0044] The embodiments of the present embodiment are the preferred embodiments of the present utility model, not limited to the protection scope of the present utility model, so: all equivalent changes made according to the structure, shape and principle of the present utility model should be covered in the protection scope of the present utility model.
