[0034] Example

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown. An assembled inspection well with an anti-fall function comprises a well body 1, and the well body 1 is installed by an existing method. The well body 1 can be installed by cast-in-place or prefabricated assembly. An anti-fall device is arranged inside the well body 1. The anti-fall device comprises a mounting seat 2, and the mounting seat 2 is a disc structure. A plurality of first support rods 3 are arranged in a circular array on the mounting seat 2, and in this embodiment, there are six first support rods 3. The first support rod 3 is slidably connected to the mounting seat 2. A slide groove is arranged on the lower surface of the mounting seat 2, and the first support rod 3 is located in the slide groove and is slidably connected to the slide groove. The slide groove is a dovetail groove or a T-shaped groove, which improves the supporting effect on the first support rod 3 and prevents the first support rod 3 from slipping out of the slide groove.

[0036] The first support rod 3 is provided with a second support rod 4 for sliding inside. Both the first support rod 3 and the second support rod 4 are rectangular rods. The rectangular cavity inside the second support rod 4 has a guiding and limiting effect on the sliding of the second support rod 4. The mounting seat 2 is provided with a power mechanism for driving the first support rod 3 and the second support rod 4 to slide synchronously. The power mechanism includes a screw rod 5, which is located at the center of the mounting seat 2 and is rotatably connected to the mounting seat 2 through a bearing. A sleeve 6 is provided outside the screw rod 5, and the sleeve 6 is threadedly connected to the screw rod 5. A limiting plate 8 with a limiting effect on the sleeve 6 is fixed at the bottom end of the screw rod 5 to prevent the sleeve 6 from sliding off the screw rod 5. Several transmission rods 7 are evenly hinged on the side wall of the sleeve 6, and the transmission rods 7 correspond to the first support rod 3 one by one. The transmission rod 7 is hinged to the first support rod 3. The screw rod 5 is rotated, and the screw rod 5 moves the sliding sleeve 6 up and down along the screw rod 5 through the threaded transmission belt 13. The sliding sleeve 6 drives the first support rod 3 to slide in the sliding groove through the transmission rod 7, thereby realizing the sliding in and out of the first support rod 3 in the mounting seat 2.

[0037] The first support rod 3 is provided with a transmission structure for driving the second support rod 4 to slide. The transmission structure includes a gear 9, and the axle of the gear 9 is rotatably connected to one end of the first support rod 3 through a bearing. A rack 10 meshing with the gear 9 is fixedly provided on the lower surface of the mounting seat 2. A driving wheel 11 is fixedly provided on the axle of the gear 9, and a driven wheel 12 is rotatably provided on the other end of the first support rod 3 through a bearing, and the driving wheel 11 and the driven wheel 12 are connected by a transmission belt 13. A fixing plate is fixedly provided at one end of the second support rod 4 located inside the first support rod 3, and a long strip-shaped through hole is provided on the lower surface of the first support rod 3 for the fixing plate to pass through, and the through hole meets the sliding requirements of the second support rod 4. The fixing plate is fixedly connected to the transmission belt 13 below the driving wheel 11 and the driven wheel 12.

[0038] The first support plate drives the gear 9 to slide synchronously, and the gear 9 rotates under the action of the rack 10. The gear 9 drives the driving wheel 11 to rotate through the wheel axle, and the driving wheel 11 drives the transmission belt 13 to rotate through the driven wheel 12. The transmission belt 13 drives the second support rod 4 to slide along the first support rod 3 through the fixed plate, thereby realizing the synchronous extension and retraction of the first support rod 3 and the second support rod 4, which is convenient for the installation of the anti-fall device.

[0039] The first protection structure is arranged on the first support rod 3. The first protection structure includes a flexible first protection rope 14, and one end of the first support rod 3 extending out of the mounting seat 2 is fixedly connected by the first protection rope 14. A plurality of flexible first longitudinal ropes 15 are evenly arranged between the first protection rope 14 and the side wall of the mounting seat 2. The two ends of the first longitudinal rope 15 are fixedly connected to the first protection rope 14 and the mounting seat 2, respectively. Since the first longitudinal rope 15 and the first protection rope 14 are both flexible ropes, during the extension and contraction process of the first support rod 3, the first protection rope 14 and the first longitudinal rope 15 are also extended and folded together, so that the first longitudinal rope 15 and the first protection rope 14 do not hinder the extension and contraction of the first support rod 3.

[0040] The second support rod 4 is provided with a second protective structure. The second protective structure includes a connecting plate 19, and the connecting plate 19 is fixedly arranged on the side wall of the second support rod 4.

The connecting plate 19 is provided with a coaxial flexible second protective rope 16 and a third protective rope 17, and the second protective rope 16 and the third protective rope 17 are respectively fixed on the two rows of connecting plates 19. The second protective rope 16 and the third protective rope 17 are fixedly connected by a second longitudinal rope 18. Since the second protective rope 16, the third protective rope 17 and the second longitudinal rope 18 are all flexible ropes, they do not interfere with the rope of the second support rod 4.

[0041] A mesh structure is formed between the first protection rope 14 and the first longitudinal rope 15 and the mounting seat 2 to protect the periphery of the mounting seat 2. A mesh structure is formed between the second protection rope 16, the third protection rope 17 and the second longitudinal rope 18 to protect the first support rod 3 and the inner wall of the well body 1, thereby improving the protection effect.

[0042] A buffer structure is provided above the mounting seat 2. The buffer structure includes a buffer plate 20, and the buffer plate 20 is located directly above the mounting seat 2. A circumvention hole 21 for circumventing the screw rod 5 is provided in the center of the buffer plate 20. A plurality of guide rods 22 are evenly fixedly provided on the upper surface of the mounting seat 2, and a first spring 23 is provided outside the guide rod 22, and the two ends of the first spring 23 are respectively fixedly connected to the buffer plate 20 and the mounting seat 2. The buffer plate 20 is buffered by the first spring 23, thereby improving the buffering effect of the anti-falling device and improving the protection effect on the faller.

[0043] like Figure 6As shown. The second support rod 4 is connected to the well body 1 through a locking structure. The locking structure includes a connecting seat 25 fixed on the inner wall of the well body 1, and the connecting seat 25 is provided with a slot 26 for inserting the second support rod 4. A mounting groove 27 is provided at the top of the slot 26, and a latch 28 is slidably provided in the mounting groove 27, and the latch 28 is connected to the mounting groove 27 through a second spring 29. The second support rod 4 is provided with a socket 24 for inserting the latch 28. The upper surface of the end of the second support rod 4 is provided with an inclined surface for facilitating the insertion of the latch 28 into the socket 24.

[0044] The installation method of the above-mentioned assembled inspection well with anti-fall function comprises the following steps:

[0045] S1. Fix the connection seat 25 on the inner wall of the well body 1. The connection seat 25 can be fixed by bolts.

[0046] S2. Rotate the screw rod 5, which drives the sleeve 6 to move upward. The sleeve 6 drives the first support rod 3 to slide along the slide groove of the mounting seat 2 through the transmission rod 7. The first support plate drives the gear 9 to slide synchronously. The gear 9 rotates under the action of the rack 10. The gear 9 drives the driving wheel 11 to rotate through the wheel axle. The driving wheel 11 drives the transmission belt 13 to rotate through the driven wheel 12. The transmission belt 13 drives the second support rod 4 to slide outward along the first support rod 3 through the fixed plate.

[0047] S3. Insert the end of the second support rod 4 into the connecting seat 25. The inclined surface of the end of the connecting seat 25 pushes the pin 28 to move upward. The second spring 29 is compressed. The second support rod 4 continues to move. After the pin 28 moves to the position of the socket 24, the pin 28 is inserted into the socket 24 under the action of the second spring 29 to complete the installation.

[0048] The anti-fall device can be disassembled by rotating the screw rod 5 in the reverse direction.

[0049] Therefore, the use of the assembled inspection well with anti-falling function and the installation method thereof described in the present invention can solve the problems of poor anti-falling effect and inconvenient installation and disassembly of existing inspection wells.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
