It is built on a foundation pit, sunk to a certain elevation with a long-arm excavator, connected to a whole with a jacking pipe, and a flow channel is made and a lid is covered. The existing caisson ladders are all separate ladders standing upright in the well, which cannot ensure the stability of the ladder and are prone to danger. At the same time, the user is prone to operating errors such as slipping hands, which may cause danger. Therefore, a new caisson climbing device is urgently needed.

[0003] After searching, the Chinese utility model patent with application publication number "CN213205528U" discloses "a caisson climbing device for bridge engineering". This application fixes the ladder through the action of a fixed structure. At the same time, when the ladder falls, it can play a protective role to prevent it from falling directly into the well. The support rod can be fixed through the cooperation of the plug rod and the ring. Through the cooperation of the support rod, the hanging ring and the connecting structure, it can be connected with the chain belt connected to the staff to prevent the staff from falling due to operational errors such as slipping of the hands, thereby protecting the safety of the users and avoiding unnecessary dangers. It is highly practical.

[0004] Since the depth of the caisson varies in different construction sites, the actual extension length of the climbing device is limited when the above-mentioned device is actually used. Therefore, the equipment has certain limitations and limited flexibility when used in practice. Therefore, the applicant proposes a new device to solve the above-mentioned problems.

[0023] 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.

[0024] When the operator enters the caisson, the operator needs to use a deep well climbing device to assist in climbing. The climbing ladder 7, as a traditional climbing device, will shake during the actual climbing process. This situation poses a safety hazard in the caisson. Based on this situation, the utility model provides a technical solution: a caisson climbing device, such as Figure 1 - Figure 2 As shown, the device comprises: a climbing ladder 7, a plurality of climbing tubes 4 are arranged inside the climbing ladder 7, each climbing tube 4 is connected to the inside of the climbing ladder 7, an auxiliary mechanism 2 is fixed on the top of the climbing ladder 7, and a connecting port 6 is opened at the bottom of the climbing ladder 7. It should be noted that in the present application, the auxiliary mechanism 2 comprises: a driving source, which is installed on one side of the top of the outside of the climbing ladder 7; two covers 203, which are respectively fixed on both sides of the top of the climbing ladder 7 and connected to the inside of the climbing ladder 7. The climbing ladder 7 has two connecting holes 6 at the bottom thereof, one of which is connected to the other connecting holes 6. The two connecting holes 6 are connected to the climbing ladder 7 by a connecting rod 204 that passes through the climbing tube 4. The driving source is used to drive one of the connecting holes 206 to rotate. The outsides of the two connecting holes 206 are both wound with climbing ropes 205 for climbing. The climbing ropes 205 are pulled out from the connecting hole 6 at the bottom of the climbing ladder 7.

[0025] In addition, reference Figure 1 and Figure 2 It can also be known that in the present application, hook claws 1 are respectively installed on the top of the two covers 203, and the hook claws 1 are used to hook at the edge of the wellhead of the caisson.

[0026] It should also be noted that the driving source is a driving motor 202, the rotating shaft of the driving motor 202 is fixed to one side of one of the winding discs 206, and the bottom of the driving motor 202 is fixed with a supporting frame 201 for fixing on one side of the outer surface of the climbing ladder 7. It should be noted that a removable rechargeable battery is installed inside the driving motor 202, and the rechargeable battery and the driving motor 202 are electrically connected.

[0027] In addition, reference Figure 1 It can be seen that in the present application, a number of fitting blocks 3 are fixed on both sides of the outer surface of the climbing ladder 7 facing the winding direction of the hook 1, and the fitting blocks 3 are used to fit with the well wall in the caisson. A force ring 5 is fixed to the end of the climbing rope 205 away from the winding disc 206, and the force ring 5 is used to pull the climbing rope 205 out of the winding disc 206, and prevent the climbing rope 205 from entering the climbing ladder 7 from the connecting port 6 when the winding disc 206 is wound.

[0028] It should be emphasized that when the caisson climbing device is actually used, first, the caisson climbing device is assembled to ensure that the climbing ladder 7, the auxiliary mechanism 2, the climbing rope 205 and other parts are firmly connected. Then, the hook 1 is fixed to the edge of the wellhead of the caisson to ensure the stable position of the climbing ladder 7. In addition, the bonding block 3 is bonded to the well wall in the caisson to increase the stability of the climbing ladder 7. In the actual climbing process, the drive motor 202 drives the winding disc 206 to rotate through the connecting rod 204, so that the climbing rope 205 is pulled out of the winding disc 206 in an orderly manner. The user holds the climbing rope 205 and climbs up along the climbing ladder 7. When the climbing rope 205 reaches the winding disc 206, the winding disc 206 automatically rewinds the climbing rope 205 to ensure the smooth progress of the climbing process. During the climbing process, if an emergency occurs, such as the climbing ladder 7 shaking, the hook 1 can be firmly hooked on the caisson to prevent the climbing ladder 7 from losing balance. At the same time, the close fit between the fitting block 3 and the inner wall of the caisson can also effectively reduce the shaking of the climbing ladder 7 and ensure the safety of the user.
