Description

Technical Field

[0001] The utility model belongs to the technical field of granaries, and in particular relates to a detachable granary ladder frame. Background Art

[0002] Grain refers to the general term for various plant seeds used in cooking food. Grain crops are rich in nutrients, mainly protein, vitamins, dietary fiber, fat, starch, etc. The storage of grain requires the use of granaries, which are special buildings for storing grain. They are used to store large amounts of grain. Ladders are needed when inspecting granaries.

[0003] Most of the existing ladder frames are fixed ladder frames assembled by welding. When the ladder frame needs to be moved, the joints of the ladder frame need to be repeatedly cut and welded, which makes the installation cost high, inefficient, and increases the labor intensity of personnel. In addition, multiple cutting and welding will damage the steel and affect the safety of the ladder frame. Therefore, we provide a detachable granary ladder frame. Utility Model Content

[0004] The purpose of the utility model is to provide a detachable granary ladder frame to solve the problems raised in the above background technology.

[0006] With the above scheme, since the threaded block and the second ladder frame are fixed by a No. 1 bolt and are threadedly connected, it can be seen that the No. 1 bolt can be quickly removed by an external tool to release the limit on the threaded block, thereby removing the connecting plate and the pin from the connection between the first ladder frame and the second ladder frame, thereby achieving the purpose of easy disassembly.

[0007] As a preferred embodiment of a detachable granary ladder frame, a concave block is clamped at the connection between the tops of the first ladder frame and the second ladder frame, and the concave block and the first ladder frame and the second ladder frame are fixedly connected by a No. 2 thread.

[0008] By adopting the above solution, the concave block and the second thread are provided to further improve the stability of the connection between the first ladder frame and the second ladder frame, thereby preventing shaking.

[0009] As a preferred embodiment of a detachable granary ladder, the surface of the No. 2 thread is threadedly connected with a nut, and the thread on the surface of the No. 2 thread is matched with the thread on the inner wall of the nut.

[0010] By adopting the above scheme, the second thread is limited and fixed by setting the nut, so as to prevent the second thread from slipping during use.

[0011] As a preferred embodiment of a detachable granary ladder, each of the first ladder and the second ladder is provided with a group of protection rods, and the number of protection rods in each group is two.

[0012] By adopting the above scheme, the protective rod is provided to protect the workers and prevent them from falling from the second ladder frame.

[0013] As a preferred embodiment of a detachable granary ladder frame, pedals are welded to the first ladder frame and the second ladder frame, and anti-slip pads are bonded to the pedals.

[0014] By adopting the above scheme and providing the anti-skid pad, workers can be prevented from slipping when climbing, thus achieving the anti-skid function.

[0015] As a preferred embodiment of a detachable granary ladder, a handle is fixedly connected to one side of the connecting plate, and the interior of the handle is a hollow structure.

[0016] By adopting the above solution, the latch can be quickly pulled out from the connection between the first ladder frame and the second ladder frame by holding the handle, which is convenient for the user to operate.

[0017] As a preferred embodiment of a detachable granary ladder rack, the size of the second ladder rack is larger than that of the first ladder rack, and the material of the second ladder rack is stainless steel.

[0018] With the above solution, since the first ladder frame and the second ladder frame are made of stainless steel, rust can be prevented during long-term use, thereby greatly improving the service life of the first ladder frame and the second ladder frame.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] 1. In the utility model, since the threaded block and the second ladder frame are fixed by a No. 1 bolt and are threadedly connected, it can be known that the No. 1 bolt can be quickly removed by an external tool to release the limit on the threaded block, so that the connecting plate and the latch can be taken out from the connection between the first ladder frame and the second ladder frame, thereby achieving the purpose of easy disassembly.

[0026] See also Figure 1-3 A detachable granary ladder frame, comprising a first ladder frame 1 and a second ladder frame 2, see Figure 3 As shown, a concave block 8 is clamped at the connection between the top of the first ladder frame 1 and the second ladder frame 2, and the concave block 8 and the first ladder frame 1 and the second ladder frame 2 are fixedly connected by a No. 2 thread 10. The arrangement of the concave block 8 and the No. 2 thread 10 further improves the stability of the first ladder frame 1 and the second ladder frame 2 when connected to prevent shaking. The connection between the first ladder frame 1 and the second ladder frame 2 at the bottom is plugged in by a pin 3, and one end of the pin 3 is fixedly connected to a connecting plate 4 located on the inner side of the second ladder frame 2, and the top and bottom of the connecting plate 4 are fixedly connected to thread blocks 5, and the thread block 5 and the second ladder frame 2 are fixedly connected by a No. 1 bolt 6. Figure 3 As shown, the surface of the No. 2 thread 10 is threadedly connected with a nut 9, and the thread on the surface of the No. 2 thread 10 is matched with the thread on the inner wall of the nut 9. Through the setting of the nut 9, the No. 2 thread 10 is limited and fixed to prevent the No. 2 thread 10 from slipping during use. Because the thread block 5 and the second ladder frame 2 are fixed by the No. 1 bolt 6, and are threadedly connected, it can be seen that the No. 1 bolt 6 can be quickly removed by an external tool to release the limitation of the thread block 5, thereby removing the connecting plate 4 and the pin 3 from the connection between the first ladder frame 1 and the second ladder frame 2, thereby achieving the purpose of easy disassembly.

[0027] See Figure 1 As shown, a set of protection bars are provided on the first ladder frame 1 and the second ladder frame 2, and each set of protection bars has two protection bars. Through the setting of the protection bars, the workers are protected to prevent them from falling from the second ladder frame 2. Figure 1 As shown, the first ladder frame 1 and the second ladder frame 2 are both welded with pedals, and the pedals are both bonded with anti-skid pads. The anti-skid pads are provided to prevent workers from slipping when climbing, thereby achieving an anti-skid function. Figure 2As shown, a handle 7 is fixedly connected to one side of the connecting plate 4, and the interior of the handle 7 is a hollow structure. By holding the handle 7, the latch 3 can be quickly pulled out from the connection between the first ladder frame 1 and the second ladder frame 2, which is convenient for the user to operate. Figure 1 As shown, the size of the second ladder frame 2 is larger than that of the first ladder frame 1, and both are made of stainless steel. Since the first ladder frame 1 and the second ladder frame 2 are made of stainless steel, rust can be prevented during long-term use, thereby greatly improving the service life of the first ladder frame 1 and the second ladder frame 2.

[0028] When in use, when the first ladder frame 1 and the second ladder frame 2 need to be dismantled, the No. 1 bolt 6 is rotated by an external tool until the No. 1 bolt 6 disengages from the inner wall of the threaded block 5, thereby releasing the limit on the threaded block 5, and then releasing the limit on the first ladder frame 1 and the second ladder frame 2. Next, the handle 7 is pulled to one side, and the connecting plate 4 is driven to move by the handle 7, and the latch 3 is driven to move by the connecting plate 4, and the latch 3 is removed from the connection between the first ladder frame 1 and the second ladder frame 2. Then, the nut 9 is rotated by an external tool again to remove the nut 9 from the surface of the No. 2 thread 10. Finally, the No. 2 thread 10 is rotated by an external tool until the No. 2 thread 10 falls off from the inner wall at the top of the first ladder frame 1 and the second ladder frame 2, and the concave block 8 is removed to release all the limit on the first ladder frame 1 and the second ladder frame 2, so that the first ladder frame 1 and the second ladder frame 2 can be separated, thereby achieving the purpose of easy disassembly.
