[0003] When maintenance personnel enter and exit the pit for maintenance, they are generally required to bring their own ladders. The ladder is large in size and heavy in weight, and the maintenance personnel carrying their own ladders in and out of the pit will increase the burden on the maintenance personnel, thereby increasing the difficulty of the maintenance personnel entering and exiting the pit. Summary of the invention
[0004] In order to facilitate maintenance personnel to enter and exit the pit, the present application provides a ladder device for an elevator pit.
[0005] The present application provides a ladder climbing device for an elevator pit, which adopts the following technical solution:
[0006] A ladder device for an elevator pit comprises a ladder body, wherein connecting rods are installed at the upper and lower parts of the ladder body, and the ends of the connecting rods away from the elevator body are connected to the inner wall of the elevator pit. The ladder body is inclined and gradually away from the inner wall of the ladder body from top to bottom.
[0007] By adopting the above technical solution, maintenance personnel can enter and exit the pit through the ladder body, so they do not need to bring their own ladder, which makes it convenient for maintenance personnel to enter and exit the pit. The connecting rod increases the distance between the ladder body and the inner wall of the pit. When maintenance personnel enter and exit the pit through the ladder body, there is a large foothold on the ladder body, which makes it convenient for maintenance personnel to enter and exit the pit. At the same time, the inclination of the ladder body is conducive to saving effort for maintenance personnel to enter and exit the pit.
[0008] Optionally, a first connecting plate is provided at one end of the connecting rod away from the ladder body, one side of the first connecting plate is arranged toward the inner wall of the pit, the first connecting plate is provided with bolts, the bolts are used to fix the first connecting plate to the inner wall of the pit, a second connecting plate is fixedly installed on one side of the first connecting plate, the second connecting plate is perpendicular to the first connecting plate, a support plate is installed on the bottom side of the second connecting plate, the support plate is used to support the connecting rod, and the connecting rod is connected to the second connecting plate.
[0009] By adopting the above technical solution, after the first connecting plate is fixed to the inner wall of the pit by bolts, the connecting rod is connected to the second connecting plate, so that it is convenient to install the ladder body on the inner wall of the pit. After the ladder body is installed on the inner wall of the pit, the support plate supports the connecting rod, thereby reducing the bending of the connecting rod.

[0011] By adopting the above technical solution, when it is necessary to enter or exit the pit, the ladder body is pushed away from the inner wall of the pit to rotate the connecting rod to be horizontally arranged, thereby increasing the distance between the ladder body and the inner wall of the pit, thereby facilitating maintenance personnel to enter or exit the pit. When the ladder body is not needed, the ladder body is pushed close to the inner wall of the pit to rotate the connecting rod to be vertically arranged, thereby facilitating the storage of the ladder body and reducing the space occupied by the ladder body.
[0012] Optionally, a torsion spring is fixedly installed between the connecting rod and the second connecting plate, and the torsion spring is used to drive the connecting rod to rotate upward, and the torsion spring is sleeved on the first shaft rod.
[0013] By adopting the above technical solution, after the maintenance personnel enter and exit the pit through the ladder body, the torsion spring drives the connecting rod to rotate upward, thereby facilitating the automatic storage of the ladder body.
[0014] Optionally, the ladder body is provided with an escape opening for avoiding the first limit block.

[0017] By adopting the above technical solution, when it is necessary to enter or exit the pit, the ladder body is pushed away from the inner wall of the pit, and the connecting rod slides out of the mounting tube, thereby conveniently increasing the distance between the ladder body and the inner wall of the pit, thereby facilitating maintenance personnel to enter or exit the pit. When the maintenance personnel do not need to climb the ladder to enter or exit the pit, the ladder body is pushed toward the inner wall of the pit, and the connecting rod enters the interior of the mounting tube, thereby facilitating the storage of the ladder body.
[0018] Optionally, a spring is fixedly connected between one end of the connecting rod away from the ladder body and one end of the mounting tube away from the ladder body, and the spring is used to drive the connecting rod to move toward the inside of the mounting tube.
[0019] By adopting the above technical solution, when the maintenance personnel do not need to climb the ladder body to enter or exit the pit, the spring drives the connecting rod to move toward the inside of the mounting tube, thereby facilitating the automatic storage of the ladder body.
[0020] Optionally, the mounting tube is inclined from one end close to the ladder body to the other end of the assembly being lifted.
[0021] By adopting the above technical solution, when the maintenance personnel step on the ladder body, the ladder body is away from the inner wall of the pit due to the inclination of the installation pipe, thereby facilitating the unfolding of the ladder body.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. By installing the ladder body on the inner wall of the pit, maintenance personnel do not need to bring their own ladder, making it convenient for maintenance personnel to enter and exit the pit;
[0024] 2. When the maintenance personnel complete the maintenance and leave the pit, they push the ladder body toward the inner wall of the pit to make the connecting rod vertical, thereby facilitating the storage of the ladder body and reducing the space occupied by the ladder body.

[0032] The following is combined with Figure 1-6 This application is described in further detail.
[0033] Example 1.
[0034] An embodiment of the present application discloses a ladder climbing device for an elevator pit.
[0035] Reference Figure 1 , Figure 2 A ladder device for an elevator pit includes a ladder body 1, and connecting rods 2 are provided at the upper and lower parts of both sides of the ladder body 1. The connecting rod 2 is provided with a second shaft rod 4, and the second shaft rod 4 rotates through one end of the connecting rod 2 and one side of the ladder body 1, and second limit blocks 6 are fixedly installed at both ends of the second shaft rod 4, and the second limit blocks 6 are used to limit the second shaft rod 4 from being pulled out from the connecting rod 2 and the ladder body 1.
[0036] The connecting rod 2 is also provided with a first connecting plate 7, and the first connecting plate 7 is provided with bolts 9. One side of the first connecting plate 7 is in contact with the inner wall of the bottom pit, and the first connecting plate 7 is fixedly installed on the inner wall of the bottom pit by bolts 9. A second connecting plate 8 is fixedly installed on one side of the first connecting plate 7, and the second connecting plate 8 is perpendicular to the first connecting plate 7.
[0037] Reference Figure 1 , Figure 2 The second connecting plate 8 is provided with a first shaft rod 3, which rotates through the second connecting plate 8 and the end of the connecting rod 2 away from the ladder body 1. First limit blocks 5 are fixedly installed at both ends of the first shaft rod 3, and the first limit blocks 5 are used to limit the first shaft rod 3 from being pulled out from the second connecting plate 8 and the connecting rod 2. A support plate 10 is fixedly installed on the bottom side of the second connecting plate 8, and the support plate 10 is used to support the connecting rod 2.
[0038] Maintenance personnel enter and exit the pit through the ladder body 1, so they do not need to bring their own ladder, which makes it convenient for maintenance personnel to enter and exit the pit. At the same time, the ladder body 1 is pushed close to or away from the inner wall of the pit, and the ladder body 1 drives the connecting rod 2 to rotate, so that the ladder body 1 is convenient to unfold or store.
[0039] Reference Figure 1 , Figure 2 The length of the connecting rod 2 at the upper part of the ladder body 1 is smaller than the connecting rod 2 at the lower part of the ladder body 1, so that the ladder body 1 is gradually inclined away from the inner wall of the ladder body 1 from top to bottom, which is conducive to saving effort for maintenance personnel to enter and exit the pit.
[0040] The implementation principle of the ladder device for an elevator pit in the embodiment of the present application is as follows: when maintenance personnel enter and exit the pit, the ladder body 1 is pushed away from the inner wall of the pit, and the connecting rod 2 is rotated downward and pressed on the support plate 10, thereby increasing the distance between the ladder body 1 and the inner wall of the pit, thereby increasing the foothold space for maintenance personnel to step on the ladder body 1. The foothold space for maintenance personnel to step on the ladder body 1 is increased, thereby facilitating maintenance personnel to enter and exit the pit.
[0041] When the maintenance personnel do not need to climb the ladder, they push the ladder toward the inner wall of the pit, and the connecting rod 2 rotates upward, so as to facilitate the storage of the ladder body 1 and reduce the space occupied by the ladder body 1.
[0042] Example 2.
[0043] An embodiment of the present application discloses a ladder climbing device for an elevator pit.
[0044] Reference Figure 3 , Figure 4 The difference between the ladder climbing device for an elevator pit in the embodiment of the present application and the embodiment 1 is that a torsion spring 11 is fixedly installed between the connecting rod 2 and the second connecting plate 8, and the torsion spring 11 is used to drive the connecting rod 2 to rotate upward, and the torsion spring 11 is sleeved on the first shaft rod 3.
[0045] When the maintenance personnel enter and exit the pit through the ladder body 1, the ladder body 1 is driven by gravity to rotate the connecting rod 2 downward and tightly against the support plate 10. After the maintenance personnel leave the ladder, the torsion spring 11 drives the connecting rod 2 to rotate upward, so that the ladder body 1 moves toward the inner wall of the pit, thereby facilitating the automatic storage of the ladder body 1.
[0046] Avoidance openings 12 are provided on both sides of the ladder body 1. When the ladder body 1 moves toward the inner wall of the pit and the connecting rod 2 rotates upward, the ladder body 1 avoids the first limit block 5 through the avoidance openings 12, thereby facilitating the vertical arrangement of the connecting rod 2 and facilitating the storage of the ladder body 1.
[0047] The implementation principle of the ladder device of an elevator pit in an embodiment of the present application is as follows: after the maintenance personnel leave the ladder body 1, the torsion spring 11 drives the connecting rod 2 to rotate upward, thereby facilitating the automatic storage of the ladder body 1.
[0048] Example 3.
[0049] An embodiment of the present application discloses a ladder climbing device for an elevator pit.
[0050] Reference Figure 5 , Figure 6 The ladder device for an elevator pit of the present application is different from the embodiment 1 in that the connecting rod 2 is fixedly connected to the ladder body 1, and the connecting rod 2 is sleeved with a mounting tube 13, which is buried in the inner wall of the pit. The end of the mounting tube 13 away from the ladder body 1 is closed. A first limit frame 14 is fixedly mounted on the inner wall of the end of the mounting tube 13 away from the inner wall of the pit, and a second limit frame 15 is fixedly mounted on the end of the connecting rod 2 away from the ladder body 1. The first limit frame 14 and the second limit frame 15 are mutually engaged, thereby reducing the possibility of the connecting rod 2 being pulled out of the mounting tube 13.
[0051] A spring 16 is fixedly connected between one end of the connecting rod 2 away from the ladder body 1 and one end of the mounting tube 13 away from the ladder body 1 . The elastic force of the spring 16 is used to drive the connecting rod 2 to move toward the inside of the mounting tube 13 .
[0052] The mounting pipe 13 is arranged to be inclined from one end close to the ladder body 1 to the other end of the assembly lifting.
[0053] The implementation principle of the ladder device for an elevator pit in an embodiment of the present application is: when a maintenance worker steps on the ladder body 1, the mounting tube 13 is tilted, so that the ladder body 1 can move away from the inner wall of the pit when the maintenance worker steps on it, thereby facilitating the unfolding of the ladder body 1.
[0054] After the maintenance personnel leave the ladder body 1 , the spring 16 drives the connecting rod 2 to retract into the mounting tube 13 , so that the ladder body 1 moves toward the inner wall of the pit, thereby facilitating the automatic storage of the ladder body 1 .
[0055] 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.
