Description

Technical Field

[0001] This utility model belongs to the field of high-altitude protection technology, specifically a European-style crane maintenance guardrail. Background Technology

[0002] With the rapid development of modern industry, European-style cranes have been widely used in various industrial scenarios due to their light weight, compact structure, and efficient and stable operation. During the long-term operation of European-style cranes, regular and professional maintenance is a necessary measure to ensure that they are always in good operating condition and to ensure operational safety. Maintenance personnel need to frequently conduct detailed inspections, maintenance, and troubleshooting work on various key parts of the crane, such as the main beam, end beam, trolley running track, and various electrical equipment installation locations. In order to effectively reduce safety risks during the maintenance process, guardrails have become an important protective facility to ensure the safety of maintenance personnel.

[0003] Publication No. CN215368668U discloses a safety guardrail for factory maintenance, including equipment to be maintained, scaffold vertical poles, scaffold horizontal poles, scaffold longitudinal poles, and scaffold clamps. Folding frames are installed between the scaffold horizontal poles and / or between the scaffold longitudinal poles. Connecting rings are provided at both the upper and lower ends of the folding frames. Connecting clamps are correspondingly installed on the scaffold horizontal poles and / or the scaffold longitudinal poles. Clamps are installed on the connecting clamps, and the connecting rings are secured within the clamps. This safety guardrail, based on the original scaffold structure, serves as a guardrail by installing folding frames between the scaffold horizontal poles and / or longitudinal poles, thereby preventing maintenance personnel from falling off the scaffold and improving scaffold safety. Simultaneously, the folding frames are installed on the connecting clamps via clamps and then connected to the scaffold through the connecting clamps, facilitating adjustment and ease of use.

[0004] However, when this device is in use, the guardrail can only protect maintenance personnel from falling outwards. If maintenance personnel fall inwards, it cannot provide protection. Therefore, a European-style guardrail for crane maintenance is proposed to protect maintenance personnel from falling inwards from heights during maintenance, thus preventing injury to maintenance personnel. Utility Model Content

[0005] To address the problems mentioned in the background section, this utility model provides a European-style crane maintenance guardrail.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective railing for the maintenance of a European-style crane, comprising a European-style crane body, a protective railing body fixed to the outside of the European-style crane body, an extension railing fixed to the top of the protective railing body, a protective mechanism provided on the outside of the extension railing, and a reinforcing mechanism installed at one end of the protective mechanism;

[0007] The protective mechanism includes a first support ring, a second support ring, and a first fiber rope. The first support ring is sleeved on the outside of the extension railing, the bottom end of the first support ring is fixed with a second support ring, and the outside of the second support ring is fixed with a first fiber rope.

[0008] The reinforcement mechanism includes a support rod, a first connecting rod, and a limiting ring. The support rod is fixed to the bottom end of the second support ring, and the first connecting rod is fixed to the bottom end of the support rod. A limiting ring is sleeved on the outside of the main body of the guardrail.

[0009] Preferably, a stainless steel locking female component is fixed to the outside of the first fiber rope, a second fiber rope is fixed to the outside of the second support ring, and a stainless steel locking male component is fixed to the outside of the second fiber rope.

[0010] Preferably, the inner wall of the first support ring is fitted to the outer wall of the extension railing, the first support ring and the extension railing are slidably connected, and the diameter of the second support ring is equal to the diameter of the limiting ring.

[0011] Preferably, the first fiber rope and the second fiber rope are symmetrically distributed about the central axis of the second support ring, and the stainless steel locking female part and the stainless steel locking female part are locked together.

[0012] Preferably, a second connecting rod is fixed to the top of the limiting ring, a limiting component is fixed to the bottom of the inside of the second connecting rod, a limiting disc is threadedly connected to the inside of the second connecting rod, and a guide groove is provided at the bottom of the limiting disc.

[0013] Preferably, there are two sets of support rods and first connecting rods, and the support rods and first connecting rods are symmetrically distributed about the central axis of the second support ring. The inner wall of the limiting ring is attached to the outer wall of the guardrail body, and the limiting ring and the guardrail body are slidably connected.

[0014] Preferably, the limiting rings are provided in several groups, and the limiting rings are arranged at equal intervals. The second connecting rods are provided in two groups, and the second connecting rods are symmetrically distributed about the central axis of the limiting rings. The top end of the limiting member is provided with an inclined surface.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model, through the combination of a first support ring, a second support ring, and a first fiber rope, enables the device to provide two-way protection for maintenance personnel and adapt to movement needs. The first support ring can slide along the extended railing, driving the second support ring and the first fiber rope to move synchronously, meeting the protection needs of maintenance personnel in different positions. Through the engagement of the stainless steel locking female and stainless steel locking female parts, the first and second fiber ropes form a ring-shaped protection, which not only prevents maintenance personnel from falling outwards but also prevents them from tilting inwards, filling the functional gap of traditional guardrails that only prevent outward falls and improving the safety of high-altitude maintenance.

[0017] This invention, through the combination of a support rod, a first connecting rod, and a limiting ring, enables the device to reinforce the protective mechanism and precisely limit the maintenance range. The limiting ring can slide along the main body of the guardrail to adapt to different maintenance areas. After the support rod and the first connecting rod are inserted into the second connecting rod, rotating the limiting plate can push the limiting component to clamp the first connecting rod, achieving a stable connection between the protective mechanism and the main body of the guardrail. This limits the activity range of maintenance personnel to a safe area, avoiding the risk of falls due to loosening of the protective mechanism. At the same time, it is easy to assemble and disassemble, and does not affect the efficiency of maintenance personnel moving between different areas. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0027] like Figures 1 to 7 As shown, this utility model provides a protective railing for the maintenance of a European-style crane, including a European-style crane body 1, a protective railing body 2 fixed to the outside of the European-style crane body 1, an extension railing 3 fixed to the top of the protective railing body 2, a protective mechanism 4 provided on the outside of the extension railing 3, and a reinforcing mechanism 5 installed at one end of the protective mechanism 4.

[0028] like Figures 1 to 5 As shown, the protective mechanism 4 includes a first support ring 401, a second support ring 402, and a first fiber rope 403. The first support ring 401 is sleeved on the outside of the extension railing 3. The bottom end of the first support ring 401 is fixed with the second support ring 402. The inner wall of the first support ring 401 is in contact with the outer wall of the extension railing 3. The first support ring 401 and the extension railing 3 are slidably connected. The diameter of the second support ring 402 is equal to the diameter of the limiting ring 503. The first fiber rope 403 is fixed to the outside of the second support ring 402. A stainless steel locking female part 404 is fixed to the outside of the first fiber rope 403. A second fiber rope 405 is fixed to the outside of the second support ring 402. A stainless steel locking male part 406 is fixed to the outside of the second fiber rope 405. The first fiber rope 403 and the second fiber rope 405 are symmetrically distributed about the central axis of the second support ring 402. The stainless steel locking female part 404 and the stainless steel locking male part 406 are engaged and connected.

[0029] The above solution involves inserting the stainless steel locking female part 404 into the stainless steel locking male part 406, so that the first fiber rope 403 and the stainless steel locking part 406 can secure the maintenance personnel. The first fiber rope 403 and the second fiber rope 405 prevent the maintenance personnel from falling. The first support ring 401 can slide on the extension railing 3, thereby accommodating the movement of maintenance personnel in different maintenance positions.

[0030] like Figures 1 to 7 As shown, the reinforcement mechanism 5 includes a support rod 501, a first connecting rod 502, and a limiting ring 503. The support rod 501 is fixed to the bottom end of the second support ring 402, and the first connecting rod 502 is fixed to the bottom end of the support rod 501. The limiting ring 503 is sleeved on the outside of the guardrail body 2. There are two sets of support rods 501 and first connecting rods 502. The support rods 501 and first connecting rods 502 are symmetrically distributed about the central axis of the second support ring 402. The inner wall of the limiting ring 503 fits against the outer wall of the guardrail body 2, and the limiting ring 503 and the guardrail body 2 are slidably connected.

[0031] like Figures 1 to 7 As shown, a second connecting rod 504 is fixed to the top of the limiting ring 503, and a limiting component 505 is fixed to the bottom of the inside of the second connecting rod 504. A limiting disk 506 is threaded inside the second connecting rod 504, and a guide groove 507 is provided at the bottom of the limiting disk 506. Several sets of limiting rings 503 are provided, and the limiting rings 503 are arranged at equal intervals. Two sets of second connecting rods 504 are provided, and the second connecting rods 504 are symmetrically distributed about the central axis of the limiting rings 503. An inclined surface is provided at the top of the limiting component 505.

[0032] The above solution involves installing limiting rings 503 on the outside of each section of the guardrail body 2. When maintenance personnel move to the area, they lift the limiting rings 503, causing the support rod 501 fixed at the bottom of the second support ring 402 and the first connecting rod 502 to insert into the limiting disc 506 and the limiting member 505. At this time, the limiting disc 506 is rotated, causing its threads to match the threads of the second connecting rod 504, thus moving downwards. As the limiting disc 506 moves downwards, it contacts the limiting member 505 through the guide groove 507, causing the limiting member 505 to contract. This contracted limiting member 505 then holds the first connecting rod 505 in place. The connecting rod 502 is clamped, and the connection between the limiting ring 503 and the second support ring 402 is completed by tightening the limiting plate 506. This restricts the movement area of ​​the maintenance personnel to a range with the limiting ring 503 as the center and the first fiber rope 403 and the second fiber rope 405 as the radius, thereby preventing the maintenance personnel from falling accidentally. After the maintenance of the current area is completed, the second support ring 402 and the limiting ring 503 on one end of the guardrail body 2 are separated and moved to the next maintenance area to be connected with the same set of limiting rings 503. Then the limiting ring 503 on the other end of the guardrail body 2 is removed and replaced in the next maintenance area to complete the connection.
