[0002] The cage ladder is an assembled light steel structure ladder, which consists of a handrail ladder, a straight ladder, a cage and connectors. It is suitable for all buildings that require maintenance ladders and safe ladders. It can be used in building maintenance and construction to play a role in safety protection. During high-altitude operations at construction sites, the ladder cage is a must-have equipment for construction workers to climb to high altitudes. For example, patent number CN202222004142.8 is a ladder cage that is easy to assemble. The device has the following shortcomings:

[0003] The device makes a detachable structure of a rectangular frame, columns, supporting platform and protective net, and assembles the cage ladder manually when in use. Since the ladder cage needs to be added layer by layer, workers need to manually carry the disassembled ladder cage structure to the platform that needs to be set up on each floor, which increases the manual transportation cost and manual setting time. In addition, adding the ladder cage to a certain height is an aerial operation, which requires the safety of the construction workers to be guaranteed. However, the device does not mention how to ensure the safety of aerial operations. Utility Model Content

[0035] The following is combined with Figure 1-6 This application is described in further detail.

[0036] The embodiment of the present application discloses a ladder cage that is easy to assemble and disassemble.

[0037] Example 1

[0038] Reference Figure 1 , 25. A ladder cage that is easy to disassemble and assemble, comprising a finished ladder cage 1 assembled on the ground, and the middle part of the finished ladder cage 1 is connected to the first cross plate 2 by a hexagonal bolt 10 through a thread, and the inner surfaces of the four corners of the first cross plate 2 are welded and fixed to the inner surfaces of the four telescopic rods 11, and the inner surfaces of the middle parts of the four telescopic rods 11 are welded and fixed to the inner surfaces of the four corners of the second cross plate 3, and not only the first cross plate 2 is connected to the finished ladder cage 1 by a hexagonal bolt 10 through a thread, but the second cross plate 3 is also connected to the finished ladder cage 1 by a hexagonal bolt 10 through a thread.

[0039] The middle part of the outer surface of both sides of the second cross plate 3 is welded and fixed to the inner surface of one side of the two first support platforms 8, and the upper surfaces of the two first support platforms 8 are respectively fixed to the lower surfaces of the two hydraulic rods 6, and the upper surfaces of the two hydraulic rods 6 are fixed to the lower surfaces of the two second support platforms 9, and the opposite side surfaces of the two second support platforms 9 are fixed to the middle part of the outer surface of both sides of the top plate 4, and the lower surfaces of the four corners of the top plate 4 are welded and fixed to the upper surfaces of the four telescopic rods 11, and the four corners of the lower surface of the top plate 4 are glued and fixed to the upper surface of the shock-absorbing block 13.

[0040] Through the above arrangement, the first cross plate 2 and the second cross plate 3 are respectively fixed to the finished ladder cage 1 by the hexagonal bolts 10, so that the entire device can be stably installed on the outside of the finished ladder cage 1, and the first cross plate 2 and the second cross plate 3 are both fixedly connected to the fixed ends of the four telescopic rods 11, providing better support and pulling force for the longitudinal movement of the telescopic rods 11, and the second cross plate 3 is fixedly connected to the first support platform 8, so that the first support platform 8 and the second cross plate 3 are integrated, providing support force for the hydraulic rod 6 fixed on the upper part of the first support platform 8, so that the hydraulic rod 6 drives the second support platform 9 fixed on the upper part to achieve longitudinal movement, and at the same time drives the top plate 4 and the telescopic rod 11 to move together, and the shock-absorbing block 13 glued to the lower part of the top plate 4 can provide a buffering and shock-absorbing effect when the top plate 4 abuts against the finished ladder cage 1, and can also prevent the top plate 4 from being deformed by force, and isolate the loss caused by friction between the top plate 4 and the finished ladder cage 1.

[0041] It should be noted that the device also requires a hydraulic pump and a hydraulic controller to control the lifting of the hydraulic rod, but since they are all existing devices, they will not be described in detail here. The telescopic rod 11 and the hydraulic rod 6 are all existing technologies and will not be described in detail here.

[0042] Reference Figure 2 , 34. The second cross plate 3 is located at the inlet and outlet side of the finished ladder cage 1 and is provided with two moving mechanisms 5. The two moving mechanisms 5 have not only the same structure but also the same installation method. The moving mechanism 5 includes a baffle 59 slidably arranged on the inner surface of the second cross plate 3, and the baffle 59 is away from the outer surface of one end of the construction platform 7, and is threadedly connected with the two telescopic rods 11 through a hexagonal bolt 10. A T-slot 55 for sliding of the T-type telescopic tube 53 is provided in the middle of the inner surface of the baffle 59, and the inner cavity surface of the T-slot 55 and the outer surface of the T-type telescopic tube 53 are slidably arranged with each other and are also limited to each other. The surface of the opening side of the T-type telescopic tube 53 is welded and fixed to the surface of one side of the supporting inclined block 51, and abuts against one end of the spring 52 on the inner wall of one side of the T-type telescopic tube 53, and the other end of the spring 52 abuts against the surface of the side where the supporting inclined block 51 and the T-type telescopic tube 53 are fixed.

[0043] The lower surface of the supporting bevel block 51 is in contact with the upper surface of the vehicle plate 56, and the vehicle plate 56 is a smooth plane, so that the supporting bevel block 51 can slide longitudinally on the smooth upper surface of the vehicle plate 56, and the four corners of the lower surface of the vehicle plate 56 are fixedly connected to the fixed ends of the four rollers 57, and the two opposite rollers 57 are slidably arranged on the outer surfaces of both sides of the limiting strip 58, and are limited to each other, and the lower surface of the limiting strip 58 is welded and fixed to the middle part of the upper surface of the bottom plate 54, and the four rollers 57 all move on the upper surface of the bottom plate 54, and the lower surface of the bottom plate 54 is welded and fixed to the upper surface of the construction platform 7 on one side of the baffle 59, and at the same time, the upper surface of the construction platform 7 is also welded and fixed to the lower surface of the baffle 59.

[0044] Through the above arrangement, the baffle plate 59 and the second cross plate 3 are slidably arranged so that the baffle plate 59 will not deviate when it moves longitudinally and can also have a certain limiting effect, and the baffle plate 59 is fixedly connected to the telescopic rod 11 so that the telescopic rod 11 can drive the baffle plate 59 to move longitudinally, thereby driving the entire moving mechanism 5 to move longitudinally, thereby facilitating the docking and installation and fixation of the finished ladder cage 1, and the T-slot 55 and the T-type telescopic tube 53 are slidably connected so that the supporting inclined block 51 fixed to the T-type telescopic tube 53 can move laterally, and the T-slot 55 and the T-type telescopic tube 53 can limit each other, and the spring 52 arranged between the T-type telescopic tube 53 and the supporting inclined block 51 can make the supporting inclined block 51 move laterally according to the squeezed state of the supporting inclined block 51. The rebound force during compression pushes the support bevel 51 back to its original position, and the car plate 56 and roller 57 at the bottom of the support bevel 51 provide support for the support bevel 51 while also assisting the lateral movement of the support bevel 51. The car plate 56 is set as a smooth plane to reduce the resistance of the support bevel 51 during retraction, and the limit bar 58 can provide a limit when the roller 57 moves, so that the roller 57 will not deviate from the track, and the limit bar 58 cooperates with the bottom plate 54 to provide a moving track for the roller 57, and the bottom plate 54 is fixedly connected to the construction platform 7 to better support the roller 57, the car plate 56, and the support bevel 51, thereby reducing the downward pressure on the T-slot 55 and the T-type telescopic tube 53.

[0045] Reference Figure 2 , 6 The construction platform 7 and the telescopic rod 11 are slidably arranged on the same side surface as the fixed support plate 12, and the outer surfaces of both ends of the fixed support plate 12 are welded and fixed to the inner surface of the two telescopic rods 11, and two grooves are provided at the fixed connection position between the fixed support plate 12 and the two telescopic rods 11, the length of the two grooves is equal to the width of the baffle 59, and the depth of the two grooves is equal to the height of the baffle 59.

[0046] Through the above-mentioned arrangement, the sliding arrangement of the fixed support plate 12 and the construction platform 7 reduces the gap between the construction platform 7 and the finished ladder cage 1, and plays a certain supporting role on the baffle 59, while the openings at both ends of the fixed support plate 12 can prevent the baffle 59 from being obstructed during longitudinal movement.

[0047] It should be noted that when the device is in the process of self-climbing, the baffle 59 needs to be separated from the telescopic rod 11, and then the construction platform 7 is pulled back to provide a standing platform for the construction personnel to operate the device when self-climbing.

[0048] The implementation principle of a ladder cage that is easy to disassemble and assemble in an embodiment of the present application is as follows: first, the staff installs the finished ladder cage 1 on the concrete pedestal, and then aligns the device with the finished ladder cage 1 through a tower crane, and sleeves it on the outside of the finished ladder cage 1, and then fixes the first cross plate 2 and the second cross plate 3 to the finished ladder cage 1 through hexagonal bolts 10, and then raises the hydraulic rod 6 through the hydraulic controller until it is about five centimeters higher than the height of the finished ladder cage 1, and then pushes out the construction platform 7, and fixes the baffle 59 to the four telescopic rods 11 through the hexagonal bolts 10.

[0049] Then, another finished ladder cage 1 is lifted by the tower crane, first suspended on the construction platform 7, and then the supporting inclined block 51 is moved to the lower part of the four corners of the finished ladder cage 1 through the cooperation of the T-slot 55 and the T-shaped telescopic tube 53, and then the roller 57 and the car plate 56 are cooperated. After alignment, the finished ladder cage 1 is slowly placed on the upper part of the supporting inclined block 51, and then the staff can push the finished ladder cage 1 to be installed to the upper part of the installed finished ladder cage 1. After the two finished ladder cages 1 are aligned, the hydraulic rod 6 is lowered by the hydraulic controller to make the two finished ladder cages 1 fit together, and then the staff can install them.

[0050] After the installation is completed, the hexagonal bolts 10 fixed between the baffle plate 59 and the telescopic rod 11 are loosened, and then the construction platform 7 is pulled back so that one end of the construction platform 7 overlaps with the second cross plate 3, and the other end overlaps with the fixed support plate 12. The staff can now stand on the construction platform 7, control the hydraulic rod 6 to descend, drive the four telescopic rods 11 to descend, and at the same time make the top plate 4 descend and overlap with the top of the finished ladder cage 1, and then remove the hexagonal bolts 10 fixing the first cross plate 2 and the second cross plate 3 to the finished ladder cage 1, and then control the hydraulic rod 6 to move longitudinally, raise the first cross plate 2 and the second cross plate 3 to the middle and upper parts of the finished ladder cage 1 that have just been installed, and reinstall the removed hexagonal bolts 10, then push out the construction platform 7, refix the baffle plate 59 and the four telescopic rods 11, and then the next finished ladder cage 1 can be installed.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
