Description

Technical Field

[0001] The utility model relates to the technical field of construction auxiliary instruments, in particular to a safety high disk type scaffold. Background Art

[0002] During the construction process, especially when carrying out construction operations at high altitudes, scaffolds are necessary. The existing Chinese patent with the application number: 202120922253.X discloses a multi-functional disk type scaffold, including a first disk buckle, a second disk buckle, a vertical pole and a cross bar. The first disk buckle is fixedly sleeved on the vertical pole, the second disk buckle is movably sleeved on the vertical pole and is located above the first disk buckle. Connecting heads are arranged at both ends of the cross bar, and a first connecting rod and a second connecting rod are symmetrically arranged at the upper and lower ends of the connecting head.

[0003] Compared with the traditional scaffold that only uses pins for connection, the above technology has better connection stability, that is, it avoids the defect that the traditional pins are prone to fall off automatically. However, when the above technology is actually used, it is necessary to first loosen the locking nuts on the first connecting rod and the second connecting rod, then pull out the second disk buckle upward, and the second connecting rod can be separated from the second disk buckle hole. Then, pull out the cross bar from the first disk buckle, and the first connecting rod can be taken out of the first disk buckle hole. At this time, after cumbersome operations, the disassembly or installation between the cross bar and the vertical pole can be completed, thus slowing down the construction progress. Therefore, in order to solve the above technical problems, we propose a safety high disk type scaffold. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and propose a safety high disk type scaffold.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A safety high disk type scaffold includes a plurality of vertical poles and a plurality of cross bars. An installation disk is fixed on the rod body of the vertical pole. A plurality of sockets are arranged on the disk body of the installation disk. A fork-shaped end is arranged at the end of the rod body of the cross bar. The fork-shaped end is inserted outside the installation disk. A locking pin is inserted corresponding to the socket. The lower end of the locking pin extends below the fork-shaped end and two check blocks are arranged on the inner side of the end. The ends of the check blocks away from each other extend outside the locking pin and abut against the outer wall of the fork-shaped end. The ends of the check blocks located inside the locking pin are commonly connected with a top spring. A sliding rod is arranged inside the locking pin. The lower end of the sliding rod is connected with the check block through two traction ropes. The upper end of the sliding rod extends above the locking pin.

[0007] Preferably, a guiding rod is arranged at the lower end inside the locking pin, and the lower end of the check block is slidably connected with the guiding rod.

[0008] Preferably, a pair of rollers are provided at the lower part inside the locking pin. A receiving groove is provided on the outer ring surface of the roller, and each towing rope is located in an adjacent receiving groove.

[0009] Preferably, a pull ring is provided at the upper end of the locking pin. A restraint rope is connected to the upper end of the pull ring, and the upper end of the restraint rope is connected to the vertical rod.

[0010] Preferably, a connecting ring is slidably sleeved on the outer ring surface of the vertical rod, and the upper ends of the restraint ropes are connected to the connecting ring.

[0011] Preferably, a protective cover is commonly provided outside the connection part of the vertical rod and the cross bar. Sealing gaskets are provided at the contact parts of the protective cover with the vertical rod and the cross bar.

[0012] Preferably, the protective cover is composed of several split covers, and the split covers are connected by screws.

[0013] A high-safety button-and-cup scaffold proposed by the present utility model has the beneficial effects as follows:

[0014] 1: In the present utility model, only one step is required for installing the locking pin. The check block pops out automatically under the action of the top spring. For disassembling the locking pin, it can be pulled by the slide bar, and only one operation step is needed. That is, compared with the traditional scheme that requires disassembling the locking nut and other rod bodies, when personnel disassemble the scaffold proposed in this scheme, they can install and disassemble it quickly. At the same time, through the setting of the check block, it can be avoided that the locking pin falls off the scaffold automatically, thus avoiding the instability of the scaffold caused by the falling-off of the locking pin and the phenomenon that the falling locking pin causes harm to the ground personnel, that is, the safety of using the scaffold is improved.

[0015] 2: In the present utility model, the setting of the restraint rope further limits the locking pin, so as to avoid it directly falling to the ground when it accidentally falls off, and further avoid the phenomenon that the locking pin causes harm to the ground pedestrians when it accidentally falls off, thus further improving the safety of using the scaffold; the setting of the protective cover can not only reduce the erosion of the external rainwater on the various components at the installation plate, but also further avoid the locking pin that accidentally breaks or falls off directly falling to the external ground, thus further improving the safety of using the scaffold; the setting of the split cover makes the protective cover have different shapes, which can adapt to different positions of the scaffold, and is convenient for subsequent maintenance, replacement and installation. At the same time, if the construction period is short or the external environment is good, that is, the rainwater pollution is low, the protective cover can be removed, thus further improving the convenience of installation and disassembly of the scaffold.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Embodiment 1

[0024] Referring to Figures 1-6 , a high - safety button - and - socket scaffolding includes a number of vertical poles 1 and a number of cross - bars 2. An installation plate 3 is fixed on the rod body of the vertical pole 1. A number of sockets are provided on the plate body of the installation plate 3. A fork - shaped end 4 is provided at the end of the rod body of the cross - bar 2. The fork - shaped end 4 is inserted outside the installation plate 3. A locking pin 5 is inserted corresponding to the socket. The lower end of the locking pin 5 extends below the fork - shaped end 4 and two check blocks 6 are provided on the inner side of the end. The ends of the check blocks 6 away from each other extend outside the locking pin 5 and abut against the outer wall of the fork - shaped end 4. The ends of the check blocks 6 located inside the locking pin 5 are commonly connected to a top spring 7. A sliding rod 8 is provided inside the locking pin 5. The lower end of the sliding rod 8 is connected to the check block 6 through two traction ropes 9. The upper end of the sliding rod 8 extends above the locking pin 5. Embodiment 2

[0025] Referring to Figures 1-6 , in the case that other parts are the same as those in Embodiment 1, the difference between this embodiment and Embodiment 1 is that:

[0026] A guide rod 10 is provided at the lower end inside the locking pin 5. The lower end of the check block 6 is slidably connected to the guide rod 10. The setting of the guide rod 10 can provide a guiding effect on the check block 6, thereby making the check block 6 more stable when moving; a pair of rollers 11 are provided at the lower part inside the locking pin 5. A receiving groove is provided on the outer ring surface of the roller 11. Each traction rope 9 is located in the adjacent receiving groove. The setting of the roller 11 can provide a guiding effect on the traction rope 9 and avoid wear between the traction rope 9 and the inner wall of the locking pin 5; a pull ring 12 is provided at the upper end of the locking pin 5. A restraint rope 13 is connected to the upper end of the pull ring 12. The upper end of the restraint rope 13 is connected to the vertical rod 1. The setting of the pull ring 12 makes it smoother for personnel to pull or pry the sliding rod 8.

[0027] A connecting ring 14 is slidably sleeved on the outer ring surface of the vertical rod 1. The upper ends of the restraint ropes 13 are connected to the connecting ring 14. The setting of the connecting ring 14 facilitates the connection and limitation of the restraint ropes 13. The setting of the restraint ropes 13 further limits the locking pin 5 to prevent it from directly falling to the ground when it accidentally falls off, thereby avoiding the phenomenon of the locking pin 5 accidentally falling and causing harm to pedestrians on the ground when the scaffolding is in use, and further improving the safety of the scaffolding during use; a protective cover 15 is commonly covered outside the connection between the vertical rod 1 and the cross rod 2. Sealing gaskets are provided at the contact points between the protective cover 15 and the vertical rod 1 and the cross rod 2. The setting of the protective cover 15 can not only reduce the erosion of the components at the installation plate 3 by external rainwater, but also further prevent the locking pin 5 that accidentally breaks or falls off from directly falling to the external ground, thereby further improving the safety of the scaffolding during use; the protective cover 15 is composed of several split covers 1501. The split covers 1501 are connected to each other by screws. The setting of the split covers 1501 makes the protective cover 15 have different shapes, which can thus adapt to different positions of the scaffolding, and is convenient for subsequent maintenance, replacement and installation. At the same time, if the construction period is short or the external environment is good, that is, the rainwater pollution is low, the protective cover 5 can be removed, thereby further improving the convenience of installation and disassembly of the scaffolding.

[0028] Principle of use and advantages: During the use of the utility model, when the vertical rod 1 and the horizontal rod 2 are in use, the vertical rod 1 is vertically installed, while the horizontal rod 2 is horizontally installed, and the end of the horizontal rod 2, i.e., the fork-shaped end 4, is clamped on the outer ring surface of the mounting plate 3 of the vertical rod 1. Subsequently, the locking pin 5 is inserted into the mounting plate 3 and the fork-shaped end 4, that is, the middle part of the locking pin 5 is located in the socket of the mounting plate 3, and the upper and lower ends of the locking pin 5 are inserted into the fork-shaped end 4. At this time, the fork-shaped end 4 and the mounting plate 3 can be fixedly connected by the locking pin 5, that is, the installation connection between the vertical rod 1 and the horizontal rod 2 is realized. At the same time, in the above process, since a pair of check blocks 6 are provided at the end of the lower end of the locking pin 5, that is, when the locking pin 5 is installed, the check blocks 6 move to both sides of the locking pin 5, so that one end of the check block 6 is located below the fork-shaped end 4. That is, at this time, under the action of the check block 6, the locking pin 5 cannot move upward, that is, the locking pin 5 cannot fall off the mounting plate 3 and the fork-shaped end 4, which solves the defect that the pin is easy to fall off when the traditional scaffolding is installed and connected simply by the pin.

[0029] At the same time, in the above process, since inclined surfaces are provided on both sides of the check block 6, when the operator installs the locking pin 5, the locking pin 5 moves downward, and the check block 6 can automatically contract into the locking pin 5 under the action of the inclined surface. That is, when the operator installs the scaffolding, directly moving the locking pin 5 downward can complete the fixation between the locking pin 5 and the check block 6 and the fork-shaped end 4. When the operator needs to disassemble the scaffolding or needs to replace the vertical column 1 and the horizontal rod 2, the operator applies force to the check block 6 by hand, that is, the check block 6 contracts into the locking pin 5, or pulls the sliding rod 8 upward. When the sliding rod 8 moves upward, it drives the two check blocks 6 to approach each other through the traction rope 9, so that the check block 6 retracts into the locking pin 5. At this time, the locking pin 5 can be directly pulled out from the fork-shaped end 4, thus completing the disassembly between the vertical rod 1 and the horizontal rod 2. Furthermore, when this solution is used, the installation of the locking pin 5 only requires one step, and the check block 6 pops out automatically under the action of the top spring 7. The disassembly of the locking pin 5 can be achieved by pulling the sliding rod 8, which also only requires one operation step. That is, compared with the traditional solution that requires disassembling the locking nut and other rod bodies, when the operator disassembles the scaffolding proposed in this solution, it can be quickly installed and disassembled. At the same time, through the setting of the check block 6, the automatic falling off of the locking pin 5 from the scaffolding can be avoided, thereby avoiding the instability of the scaffolding caused by the falling off of the locking pin 5 and the phenomenon that the falling locking pin 5 causes harm to the ground personnel, that is, the safety of using the scaffolding is improved.

[0030] It should be further noted that the setting of the guide rod 10 can provide a guiding effect on the check block 6, thereby making the check block 6 move more stably; the setting of the roller 11 can provide a guiding effect on the towing rope 9 and avoid wear between the towing rope 9 and the inner wall of the locking pin 5; the setting of the pull ring 12 makes it more smooth for personnel to pull or pry the sliding rod 8; the setting of the connecting ring 14 facilitates the connection and limitation of the restraint rope 13, and the setting of the restraint rope 13 further limits the locking pin 5 to prevent it from directly falling to the ground when it accidentally falls off, thereby avoiding the phenomenon of the locking pin 5 causing harm to pedestrians on the ground when it accidentally falls off, and further improving the safety of the scaffolding during use; the setting of the protective cover 15 can not only reduce the erosion of the components at the mounting plate 3 by external rainwater, but also further prevent the locking pin 5 that accidentally breaks or falls off from directly falling to the external ground, thereby further improving the safety of the scaffolding during use; the setting of the split cover 1501 makes the protective cover 15 have different shapes, which can thus adapt to different positions of the scaffolding, facilitate subsequent maintenance, replacement and installation, and at the same time, if the construction period is short or the external environment is good, that is, the rainwater pollution is low, the protective cover 5 can be removed, thereby further improving the convenience of the installation and disassembly of the scaffolding.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
