[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-6The utility model provides a technical solution: an elevator pit ladder installation device, including an elevator pit 1, two positioning blocks 2 are arranged at the inner bottom of the elevator pit 1, a crossbar 21 is connected to the middle of the positioning block 2, a mobile mechanism is connected to one side of the crossbar 21, a ladder 4 is connected to one side of the mobile mechanism, an adjustment mechanism is connected to one side of the ladder 4, the adjustment mechanism corresponds to the elevator pit 1, and a fixing mechanism is connected to one side of the positioning block 2, and the fixing mechanism corresponds to the mobile mechanism; when the staff puts the ladder to the designated position, the upper adjustment mechanism is against the top of the elevator pit 1, and the two positioning blocks 2 are against the inner bottom of the elevator pit 1. At this time, when the staff needs to adjust the angle of the ladder 4, the crossbar 21 is rotated, and the mobile mechanism will move with the bottom of the ladder 4, and the top will also be adjusted accordingly because of the adjustment mechanism. By providing a mobile mechanism and a fixing mechanism, the device can complete the adjustment of the angle of the ladder 4 by rotating, which is easy to operate and reduces manpower. At the same time, the fixing mechanism can fix the mobile mechanism to ensure stability during operation. The adjustment mechanism cooperates with the mobile mechanism to ensure that the ladder 4 can adjust the angle normally.

[0028] The moving mechanism includes a round block 22, which is fixedly connected to the middle of the cross bar 21, a rocker 28 is fixedly connected to one side of the round block 22, a first bevel gear 23 is fixedly connected to both ends of the cross bar 21, a second bevel gear 24 is meshedly connected to one side of the first bevel gear 23, a rotating rod 25 is fixedly connected to the inside of the second bevel gear 24, a slider 26 is connected to the outside of the rotating rod 25, a groove is provided inside the positioning block 2, the slider 26 and the groove are slidably connected, the slider 26 is fixedly connected to the bottom of the ladder 4, the round block 22 and the fixing mechanism Correspondingly, when the staff is ready to adjust the angle of the ladder 4, the staff holds the rocker 28 and manually rotates the round block 22, which causes the fixedly connected crossbar 21 to rotate, so that the first bevel gear 23 on one side rotates, and the second bevel gear 24 meshing with it also rotates, so that the middle rotating rod 25 rotates, and the slider 26 is driven to move inside the groove while rotating. By adjusting the rotation direction of the round block 22, the slider 26 can be controlled to move forward or backward, thereby realizing the movement of the ladder 4 fixedly connected at the top. The device is provided with a moving mechanism, and the movement of the sliders 26 on both sides can be realized by rotating the round block 22, which is simple to operate and reduces the difficulty and cost of operation.

[0029] A thread is provided on the outer side of the rotating rod 25, and the rotating rod 25 and the slider 26 are threadedly connected; because of the threaded connection, when the rotating rod 25 rotates, the slider 26 should rotate and move together, but the slider 26 is inside the groove, and the groove limits the rotation of the slider 26. Therefore, the slider 26 can only move with the rotation of the rotating rod 25, thereby realizing the angle adjustment of the device.

[0030] The rotating rod 25 and the interior of the positioning block 2 are rotationally connected, the connection between the cross bar 21 and the positioning block 2 is rotationally connected, and the first bevel gear 23 and the second bevel gear 24 are located inside the positioning block 2; the positioning block 2 provides a certain supporting force for the rotating rod 25 and supports the rotation of the rotating rod 25. The reasons for the cross bar 21 and the positioning block 2 are the same, and the positioning block 2 provides supporting force for the cross bar 21.

[0031] The fixing mechanism includes an L-shaped block 3, which is fixedly connected to the positioning block 2. A hollow block 31 is fixedly connected to one side of the L-shaped block 3. The interior of the hollow block 31 is slidably connected to a moving rod 34, which corresponds to the round block 22. A long through groove 32 and a short through groove 33 are provided inside the hollow block 31. A thin rod 36 is fixedly connected to the interior of the moving rod 34, which corresponds to the long through groove 32 and the short through groove 33. A spring 37 is provided on the outside of the moving rod 34, and one end of the moving rod 34 is fixedly connected to a rotating block 35. When the staff adjusts the angle of the ladder 4 through the moving mechanism, the moving rod 34 should extend into the circular groove 27 of the round block 22, so that the round block 22 can be fixed and no longer rotated or moved. When the staff needs to adjust the angle again, at this time, the moving rod 34 can be pulled by the rotating block 35, so that one end of the moving rod 34 leaves the inside of the circular groove 27, and the moving rod 34 is retracted into the inside of the hollow block 31. At this time, the internal spring 37 is compressed, and the thin rod 36 moves from the left side of the long through groove 32 to the right side, slightly moving out of the positioning block 2. Then the staff rotates the rotating block 35, and the thin rod 36 becomes perpendicular to the original direction. At this time, the rotating block 35 is released, and under the rebound force of the spring 37, the thin rod 36 is 6 will move into the short through slot 33 and stop at the bottom of the short through slot 33, but at this time the moving rod 34 is still inside the positioning block 2. The short through slot 33 is only provided to temporarily fix the moving rod 34, so that the staff can easily rotate the round block 22. When the round block 22 needs to be stopped, the thin rod 36 is pulled out from the short through slot 33 and rotated again. Under the rebound force of the spring 37, the thin rod 36 will return to the bottom of the long through slot 32 again. At this time, the moving rod 34 enters the inside of the round slot 27 to achieve fixation. By providing a fixing mechanism, the device can fix the moving mechanism to prevent the round block 22 from rotating, which can improve the stability during operation.

[0032] A circular groove 27 is formed on one side of the round block 22, and the moving rod 34 corresponds to the circular groove 27; one end of the moving rod 34 is just sized to match the round block 22, and can be inserted into the inside of the round block 22 to achieve fixation.

[0033] One end of the moving rod 34 is fixedly connected with a ring block, which corresponds to the circular groove 27, and the spring 37 is fixedly connected to one end of the ring block. A circular ring is fixedly connected to the inside of the hollow block 31, and the circular ring is on one side of the thin rod 36, and the circular ring and the spring 37 are fixedly connected; the end of the moving rod 34 close to the circular groove 27 is thicker than the other end, that is, the so-called ring block, which just matches the size of the circular groove 27, and the ring block is a part of the moving rod 34. The ring block is slidably connected to the inside of the hollow block 31, and the inside of the hollow block 31 is fixedly connected with the circular ring, and the spring 37 is located in the middle of the ring block and the circular ring. The circular ring is fixed, and the ring block moves, so that the spring 37 in the middle can be compressed, and the circular ring is on the left side of the thin rod 36, because it cannot block the movement of the thin rod 36, so the overall device is more reasonable.

[0034] The adjustment mechanism includes a block 11, which is connected to the elevator pit 1. A slide groove is provided on one side of the block 11. A block 12 is slidably connected inside the slide groove. The top of the ladder 4 is connected to the block 12 in a rotating manner. When the bottom of the ladder 4 moves, the top also needs to move to a certain extent, that is, the block 12 slides inside the slide groove. When the bottom is fixed, the top is also fixed. The top of the ladder 4 is connected to the block 12 in a rotating manner to prevent it from getting stuck during adjustment. By providing an adjustment mechanism, in coordination with the moving mechanism, the angle adjustment can be better completed.

[0035] A weight block 29 is fixedly connected to the middle of the two positioning blocks 2; the weight block 29 can improve the overall stability of the device.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
