Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, specifically to an attached lifting scaffold guide rail. Background Technology

[0002] Attached lifting scaffolding (also known as climbing scaffolding) is a widely used external protective working platform in high-rise building construction, mainly used for the construction, decoration, and safety protection of the main structure's exterior walls. It achieves its lifting function through a support system attached to the building structure, offering advantages such as material savings, increased efficiency, and reduced safety risks, and its application is becoming increasingly widespread, especially in super high-rise buildings.

[0003] In practical engineering, the total length of guide rails in scaffolding needs to be flexibly adjusted according to the building's floor height or construction stage, making reliable connections between guide rails crucial. Currently, there are various connection methods between adjacent guide rails, including bolt connections, insert plate connections, and plug-and-socket adapter bolt fixing methods. When connecting adjacent guide rails with bolts, it is essential to prevent bolt loosening. Moreover, to ensure the reliability of the connection between adjacent guide rails, two or more bolts are usually required. However, the multiple connecting bolts between adjacent guide rails are often in an independent state, which not only requires anti-loosening operations to be performed one by one, making the process cumbersome and prone to potential hazards due to insufficient consistency in operation; more importantly, independent bolts lack a coordinated anti-loosening mechanism, and once a single bolt loosens, it is difficult for other bolts to effectively restrain it, easily triggering a chain reaction of loosening, resulting in weak overall anti-loosening ability, especially under conditions of vibration and impact, where the risk is even higher. Based on this, this application proposes an attached lifting scaffold guide rail. Utility Model Content

[0004] This utility model provides an attached lifting scaffold guide rail, which solves the problem mentioned in the background art that when connecting adjacent guide rails, multiple bolts are in an independent state, which not only requires anti-loosening operations to be performed one by one, which is cumbersome and easily affects consistency due to differences in operation; but also lacks a coordinated anti-loosening mechanism, resulting in weak overall anti-loosening ability.

[0005] This utility model provides the following technical solution: an attached lifting scaffold guide rail, including a guide rail body adapted to the attached lifting scaffold, a positioning block is provided at one end of the guide rail body, a positioning hole adapted to the positioning block is provided at the other end of the guide rail body, and a fixing ear is provided on the back of both ends of the guide rail body. Two adjacent guide rail bodies are connected by a first bolt adapted to the positioning hole and a second bolt adapted to the fixing ear. The first bolt and the second bolt are mechanically locked by a locking structure.

[0006] The locking structure includes a locking rod, a washer connected to the locking rod, and a fixing sleeve connected to the side of the washer near the locking rod. The washer is adapted to the first bolt. The inner cavity of the fixing sleeve is connected to a limit sleeve through a first spring. A positioning rod is movably connected to the top of the inner cavity of the fixing sleeve. The positioning rod is connected to the fixing sleeve through a second spring.

[0007] The second bolt has a through hole in the middle of the nut and the bottom of the screw that is adapted to the locking rod. The nut of the first bolt includes a screwing part, a middle part that is movably connected to the inner cavity of the fixed sleeve, and a connecting part that is movably connected to the inner cavity of the limiting sleeve. The middle part is provided with a locking groove that is adapted to the positioning rod.

[0008] Preferably, the outer diameter of the limiting sleeve is the same as the outer diameter of the middle part, and the inner diameter of the limiting sleeve is larger than the diameter of the threaded hole.

[0009] Preferably, one side of the positioning block and the positioning hole is provided with a threaded hole that is adapted to the screw portion of the first bolt.

[0010] Preferably, when two adjacent guide rail bodies are connected by a second bolt, the through holes on the two adjacent second bolts are at the same height, and the nuts of some of the second bolts are set facing upwards, while the rest are installed facing downwards, forming a limiting structure through the contact between the nuts and the guide rail bodies.

[0011] Preferably, the length of the locking rod is not less than the length of the fixing ear.

[0012] Preferably, the outer diameters of the screwing part, the intermediate part, and the connecting part are reduced, the thickness of the connecting part is the same as the thickness of the limiting sleeve, and the outer diameter of the connecting part is larger than the diameter of the threaded hole.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The attached lifting scaffold guide rail adopts a combination of first inserting and positioning, fixing with the first bolt, and then fixing with the fixing ear and the second bolt to achieve double positioning, which greatly improves the connection accuracy. In addition, the double fixing can distribute the load and enhance the overall connection strength.

[0015] 2. In this attached lifting scaffold guide rail, the first bolt and the second bolt are locked together through a locking structure. The locking structure also creates an interlocking constraint relationship between the first bolt and the second bolt, eliminating the risk of independent loosening between the bolts and eliminating the need to install anti-loosening components one by one. This significantly improves the overall anti-loosening reliability and maintenance convenience of the connection system. Attached Figure Description

[0023] 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.

[0024] This utility model provides one embodiment; please refer to [link / reference]. Figures 1-6 This application proposes an attached lifting scaffold guide rail, including a guide rail body 1 adapted to the attached lifting scaffold. One end of the guide rail body 1 is provided with a positioning block 11, and the other end of the guide rail body 1 is provided with a positioning hole 10 adapted to the positioning block 11. Fixing ears 5 are provided on the back of both ends of the guide rail body 1. One side of the positioning block 11 and the positioning hole 10 is provided with a threaded hole 12 adapted to the screw part of the first bolt 8. Two adjacent guide rail bodies 1 are connected by the first bolt 8 adapted to the positioning hole 10 and the second bolt 7 adapted to the fixing ear 5.

[0025] As can be seen from the above description, when this application is used, the connection between two adjacent guide rails adopts a combination of first inserting and positioning, fixing with the first bolt, and then fixing with the fixing lug 5 and the second bolt 7 to achieve double positioning, which greatly improves the connection accuracy. In addition, the double fixing can distribute the load and enhance the overall connection strength.

[0026] The first bolt 8 and the second bolt 7 are mechanically locked together by a locking structure. The locking structure limits the first bolt 8 and the second bolt 7 to prevent them from loosening under vibration or other conditions, thus ensuring the reliability of the connection between the two adjacent guide rail bodies.

[0027] The locking structure includes a locking rod 6. The nut and bottom of the second bolt 7 each have a through hole 2 adapted to the locking rod 6. The length of the locking rod 6 is not less than the length of the fixing lug 5. When two adjacent guide rail bodies are connected by the second bolt 7, the through holes 2 on the two adjacent second bolts 7 are at the same height. This configuration allows the locking rod 6 to be simultaneously inserted into the through holes 2 of multiple second bolts 7, achieving synchronous locking of multiple second bolts 7 and significantly improving the locking efficiency of the second bolts 7. Furthermore, some of the second bolts 7 have their nuts facing upwards, while the rest are installed downwards. The contact between the nut and the guide rail body 1 forms a limiting structure, replacing the tightening function of the traditional nut, thus eliminating the nut assembly process and improving the connection reliability of adjacent guide rail bodies 1. The length of the locking rod 6 can be set according to requirements and is not limited here.

[0028] One end of the locking rod 6 is connected to a washer 13, which is compatible with the first bolt 8. When the second bolt 7 is locked by the locking rod 6, the washer 13 is in a tight fit with the guide rail body 1. The operator can adjust the position of the washer 13 so that the hole on the washer 13 is aligned with the threaded hole 12 on the positioning insertion hole 10, thereby eliminating the step of placing a washer compatible with the first bolt 8 separately and simplifying the assembly process of connecting two adjacent guide rail bodies 1 by the first bolt 8.

[0029] A fixing sleeve 15 is connected to the side of the gasket 13 near the locking rod 6. The inner cavity of the fixing sleeve 15 is connected to a limiting sleeve 18 through a first spring 19. The limiting sleeve 18 is connected to the end of the first spring 19 near the locking rod 6. A positioning rod 16 is movably connected to the top of the fixing sleeve 15 away from the gasket 13. The positioning rod 16 is connected to the fixing sleeve 15 through a second spring 17. When the first spring 19 is in the normal state, the limiting sleeve 18 is located below the positioning rod 16, and the limiting sleeve 18 limits the positioning rod 16. At this time, the second spring 17 is in a stretched state. When the limiting sleeve 18 is released from the restriction on the positioning rod 16, the bottom end of the positioning rod 16 can be inserted into the inner cavity of the fixing sleeve 15 under the action of the rebound force of the second spring 17.

[0030] The nut of the first bolt 8 has a stepped structure, comprising a tightening part 14, an intermediate part 3 that is movably connected to the inner cavity of the fixing sleeve 15, and a connecting part 4 that is movably connected to the inner cavity of the limiting sleeve 18. The dimensions of the tightening part 14, the intermediate part 3, and the connecting part 4 gradually decrease. The outer diameter of the connecting part 4 is larger than the diameter of the threaded hole 12, and the thickness of the connecting part 4 is the same as the thickness of the limiting sleeve 18. The size of the nut of the first bolt 8 can be set according to requirements and is not limited here. The outer diameter of the limiting sleeve 18 is the same as the outer diameter of the intermediate part 3, and the inner diameter of the limiting sleeve 18 is larger than the outer diameter of the connecting part 4. The size of the limiting sleeve 18 can be set according to requirements and is not limited here.

[0031] The middle part 3 is provided with a locking groove 9 that is adapted to the positioning rod 16. When the first bolt 8 is screwed in, the connecting part 4 and the middle part 3 are gradually screwed into the inner cavity of the fixing sleeve 15. After the connecting part 4 contacts the limiting sleeve 18, the continued screwing of the connecting part 4 can squeeze the limiting sleeve 18. Under the action of the squeezing force, the limiting sleeve 18 gradually moves away from the positioning rod 16. When the limiting sleeve 18 is in contact with the gasket 13, the positioning rod 16 and the locking groove 9 are aligned. Under the action of the rebound force of the second spring 17, the bottom end of the positioning rod 16 can be inserted into the locking groove 9 to achieve mechanical locking of the first bolt 8. At this time, the two adjacent guide rail bodies 1 are connected by the first bolt 8. The connecting part 4 and the gasket 13 are tightly in contact, and the gasket 13 is used to constrain the first bolt 8, further improving the stability of the first bolt 8.

[0032] When the positioning rod 16 is inserted into the locking groove 9, the top end of the positioning rod 16 is exposed outside the fixing sleeve 15, which makes it easy for the user to pull the positioning rod 16 outward, release the locking of the positioning rod 16 to the first bolt 8, and facilitate the removal of the two adjacent guide rail bodies 1.

[0033] As described above, the first bolt 8 and the second bolt 7 are linked and locked through a locking structure. The locking structure also enables the first bolt 8 and the second bolt 7 to form an interlocking constraint relationship, eliminating the risk of independent loosening between the bolts and eliminating the need to install anti-loosening components one by one. This significantly improves the overall anti-loosening reliability and maintenance convenience of the connection system.

[0034] In summary: When using this attached lifting scaffold guide rail, the first section of the guide rail body 1 is fixed to the wall using a wall-mounted bracket adapted to the guide rail, and the back of the guide rail body 1 is connected to the wall-mounted bracket. The ends of adjacent guide rail bodies 1 are brought close together, and the positioning holes 10 and positioning blocks 11 are aligned. After the positioning blocks 11 are inserted into the positioning holes 10 of the adjacent guide rail bodies 1, the fixing ears 5 on the adjacent guide rail bodies 1 are aligned, and the threaded holes on the adjacent fixing ears 5 that are adapted to the second bolts 7 are aligned. The adjacent fixing ears 5 are connected using the second bolts 7, achieving initial fixation of the two adjacent guide rail bodies 1. At this time, the through holes 2 on the two adjacent second bolts 7 are at the same height. The user simultaneously inserts the locking rod 6 into the through holes 2 of multiple second bolts 7, thereby achieving synchronous locking of multiple second bolts 7. Some of the second bolts 7 have their nuts facing upwards, while the rest are installed downwards.

[0035] The user adjusts the position of the shim 13 so that the hole on the shim 13 is aligned with the threaded hole 12 on the positioning insertion hole 10. The user then screws on the first bolt 8 to re-fix the two adjacent guide rail bodies 1. During the screwing of the first bolt 8, the connecting part 4 and the middle part 3 gradually screw into the inner cavity of the fixing sleeve 15. After the connecting part 4 contacts the limiting sleeve 18, the continued screwing of the connecting part 4 can compress the limiting sleeve 18. Under the action of the compressive force, the limiting sleeve 18 gradually moves away from the positioning rod 16. When the limiting sleeve 18 is in contact with the shim 13, the positioning rod 16 is aligned with the locking groove 9. Under the action of the rebound force of the second spring 17, the bottom end of the positioning rod 16 can be inserted into the locking groove 9 to achieve mechanical locking of the first bolt 8.

[0036] The first bolt 8 and the second bolt 7 are linked and locked through a locking structure. The locking structure also makes the first bolt 8 and the second bolt 7 interlock and constrain each other, eliminating the risk of independent loosening between bolts and eliminating the need to install anti-loosening components one by one. This significantly improves the overall anti-loosening reliability and maintenance convenience of the connection system.

[0037] After the guide rail is installed, the attached lifting scaffold is connected to the guide rail through guide wheels or other structures. The front of the guide rail is located on the side closest to the attached lifting scaffold, so that the guide rail can limit the attached lifting scaffold during the lifting process and prevent the attached lifting scaffold from tilting.

[0038] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each structure adopt conventional technical means such as bolt connection in the existing technology. The machinery, parts and equipment adopt conventional models in the existing technology.
