Description

Technical Field

[0001] This utility model relates to the field of protective equipment technology, and in particular to a fall protection device for a mobile platform. Background Technology

[0002] The mobile platform is a multi-level high-altitude work platform for personnel to operate and maintain large equipment. Taking precautions against falls from the mobile platform is essential. When the mobile platform is closed, it has two states: one where it surrounds the large equipment and the other where it does not. In the state where it surrounds the large equipment, there is an irregular gap of about 20cm between the small flap of the mobile platform and the large equipment. When workers are maintaining the large equipment, tools may fall through this gap and injure the workers below.

[0003] The existing technology has the following problems:

[0004] Currently, when maintaining large equipment, the gap between the mobile platform and the large equipment may cause tools to fall or workers to step into empty spaces, posing a high safety hazard. However, the existing technology directly uses panels to form a barrier, which is difficult to completely fill the gap. At the same time, the panels are not fixed and are prone to movement.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-6As shown, a fall protection device for a mobile platform includes a mounting base 1, a mounting seat 2 fixedly connected to the right side of the mounting base 1, a small flap 3 of the mobile platform movably sleeved on the inner side of the mounting seat 2, a base 4 fixedly sleeved on the inner side of the small flap 3 of the mobile platform, a fixing mechanism 5 fixedly connected to the middle of the upper side of the base 4 away from the mounting base 1, a barrier mechanism 6 rotatably connected to the upper side of the fixing mechanism 5, and an airbag 7 movably sleeved on the inner side of the mounting base 1.

[0027] The enclosure mechanism 6 includes two vertical rods 61, which are symmetrically distributed front and back. A telescopic frame 62 is movably installed between the two vertical rods 61. Rotating tubes 63 are rotatably connected to the outer sides of both vertical rods 61. Several vertically distributed clamping shafts 65 are fixedly connected to the right side of the rotating tube 63 on the front side, and several vertically distributed clamping plates 64 are rotatably connected to the right side of the rotating tube 63 on the rear side.

[0028] It should be noted that the airbag 7 consists of a cloth cover and multiple tubular air bags, so that if one of the air bags is damaged, it can be directly replaced. The outer side is covered with felt to prevent the cloth bag from being scratched. The telescopic frame 62 can control the distance between the vertical rods 61. Multiple enclosure mechanisms 6 form a near circle. The rotating tube 63 is movably sleeved on the inner side of the card plate 64 on the adjacent enclosure mechanism 6.

[0029] like Figure 4 As shown, the fixing mechanism 5 includes a fixing seat 51. The lower side of the fixing seat 51 is fixedly connected to the middle of the upper side of the base 4 away from the card seat 1. The inner side of the fixing seat 51 is movably sleeved with a socket 59. The outer side of the fixing seat 51 is movably sleeved with a limit sleeve 52. The inner side of the side wall of the fixing seat 51 is movably sleeved with a number of annularly distributed balls 53. The outer side of the socket 59 is provided with a slot 54. The outer side of the balls 53 is movably sleeved on the inner side of the slot 54. The upper side of the socket 59 is rotatably connected to the lower side of the vertical rod 61.

[0030] It should be noted that when the limiting sleeve 52 is on the upper side, the limiting sleeve 52 restricts the ball 53, causing the ball 53 to be stuck inside the slot 54, so that the socket 59 cannot be pulled out from the inside of the fixing seat 51.

[0031] like Figure 4 As shown, the upper side of the fixed base 51 near the outer side is provided with several annularly distributed limiting holes 55, and the lower surface of the upper circular plate of the socket 59 is fixedly connected with several annularly distributed round shafts, and the round shafts are movably sleeved inside the limiting holes 55.

[0032] It should be noted that the limiting hole 55 is used to limit the socket 59, so that the socket 59 and the fixed base 51 cannot rotate relative to each other, thus reducing friction.

[0033] like Figure 4As shown, a number of annularly distributed limiting grooves 56 are provided on the outer side of the fixed base 51 near the bottom, and the protrusion on the inner side of the limiting sleeve 52 near the bottom is slidably connected to the inner side of the limiting grooves 56.

[0034] It should be noted that the limiting groove 56 is shaped like a "7", which means that the limiting sleeve 52 needs to rotate a small distance before it can fall.

[0035] like Figure 4 As shown, a guide sleeve 57 is movably installed on the outer side of the limiting sleeve 52 near the bottom. A sliding sleeve 58 is movably sleeved on the outer side of the guide sleeve 57. The lower side of the sliding sleeve 58 is fixedly connected to the upper side of the base 4.

[0036] It should be noted that a torsion spring is provided between the guide sleeve 57 and the limiting sleeve 52, so that the guide sleeve 57 restricts the limiting sleeve 52, so that the limiting sleeve 52 is on the uppermost side and cannot rotate on its own.

[0037] like Figure 6 As shown, a rotating rod 66 is rotatably connected to the right side of the uppermost clamping plate 64 near the rear side, and a screw 67 is threadedly connected between the front end of the rotating rod 66 and the right side of the clamping plate 64.

[0038] It should be noted that the lower side of the rotating rod 66 and the clamping plate 64 together clamp the clamping shaft 65, so that the clamping plate 64 cannot detach from the clamping shaft 65.

[0039] like Figure 6 As shown, a connecting rod 68 is rotatably connected to the right side of the card plate 64 near the front.

[0040] It should be noted that the linkage 68 is used to link all the clamping plates 64, so that when one of the clamping plates 64 is rotated, the other clamping plates 64 will rotate accordingly, and when the uppermost clamping plate 64 is fixed, the other clamping plates 64 are also fixed.

[0041] The working principle of this utility model is as follows: First, the airbag 7 consists of a cloth cover and multiple tubular air bags, allowing for direct replacement if one air bag is damaged. Felt is provided on the outside to prevent the cloth bag from being scratched. The telescopic frame 62 can control the distance between the vertical rods 61. Multiple enclosure mechanisms 6 form a near-circular shape. The rotating tube 63 is movably sleeved on the inner side of the clamping plate 64 on the adjacent enclosure mechanism 6. The lower side of the rotating rod 66, together with the clamping plate 64, clamps the clamping shaft 65, preventing the clamping plate 64 from detaching from the clamping shaft 65. The clamping seat 1 is fixed to the small flip plate 3 of the movable platform. The airbag 7 then seals the gap between the large equipment and the small flip plate 3 of the movable platform. Finally, the enclosure mechanism 6 is used to enclose the surrounding area, preventing workers from entering. If an employee accidentally steps on the airbag 7, it prevents tools from falling through the gap, reducing potential work hazards. Finally, when the limiting sleeve 52 is on the upper side, it restricts the ball 53, causing the ball 53 to be stuck inside the slot 54, preventing the socket 59 from being pulled out from the inside of the fixed base 51. The limiting groove 56 is shaped like a "7", requiring the limiting sleeve 52 to rotate a small distance before it can fall. A torsion spring is provided between the guide sleeve 57 and the limiting sleeve 52, allowing the guide sleeve 57 to restrict the limiting sleeve 52, keeping the limiting sleeve 52 on the uppermost side and preventing it from rotating on its own. By pushing down the limiting sleeve 52, the socket 59 can be inserted into or removed from the inside of the fixed base 51. Resetting the limiting sleeve 52 fixes the socket 59 inside the fixed base 51, allowing the enclosure mechanism 6 to be quickly installed or removed from the base 4, facilitating maintenance and other operations.
