Detailed Description

The technical solutions in the present application will be described in further detail below with reference to the accompanying drawings.

The embodiment of the application discloses safety inspection cat ladder for concrete mixing plant. Referring to fig. 1, the safety inspection ladder stand for the concrete mixing plant comprises a ladder stand body 1 fixedly arranged on a wall body. The support frames 2 are fixedly arranged on two sides of the ladder stand body 1, and the support frames 2 extend along the length direction of the ladder stand body 1. Be provided with storage box 3 in the slip between two support frames 2, storage box 3's top sets up for the opening for the instrument that the staff can carry with needs is placed in storage box 3. A space for workers to climb is formed between the storage box 3 and the ladder stand body 1, and the workers cannot be hindered.

Be provided with on storage box 3 and be used for preventing the subassembly of preventing weighing down that storage box 3 falls for storage box 3 can not take place the condition of falling when moving along support frame 2 towards the top of cat ladder body 1, has promoted the security greatly. Shoulder straps 4 are fixedly arranged on two sides of the storage box 3, so that a worker can carry the storage box 3 on his body. When climbing cat ladder body 1, the staff can drive storage box 3 and rise together, has made things convenient for the staff to the carrying of instrument, has liberated staff's both hands for staff factor of safety is higher when climbing cat ladder body 1.

Referring to fig. 1 and 2, a guide post 21 is fixedly provided on the support frame 2, the guide post 21 extends along the longitudinal direction of the ladder body 1, and the cross-sectional shape of the guide post 21 is square. The sliding grooves 31 matched with the guide posts 21 are formed in the two sides of the storage box 3, so that the guide posts 21 can enter the sliding grooves 31 and are connected with the sliding grooves 31 in a sliding mode. Guide post 21 has played direction and spacing effect to storage box 3 for storage box 3 is more steady when removing, and difficult emergence is crooked.

Referring to fig. 2, in order to save labor when the worker moves the storage box 3, a plurality of rollers 32 are rotatably disposed at both sides of the storage box 3. The rollers 32 are located in the chute 31 and are uniformly arranged along the length direction of the chute 31. The roller 32 is abutted against the guide post 21, and when the storage box 3 moves, the roller 32 rolls on the guide post 21, so that the storage box 3 and the guide post 21 are changed from sliding friction to rolling friction, and the abrasion to the storage box 3 is greatly reduced.

Referring to fig. 3, the fall preventing assembly includes a ratchet rack 51 fixedly installed on the guide post 21, pawls 52 hinged to both sides of the storage box 3, and an elastic member for pushing the pawls 52 to rotate toward a direction close to the ratchet rack 51. The ratchet bars 51 correspond to the guide posts 21 one by one, and the ratchet bars 51 extend along the length direction of the guide posts 21. The pawl 52 is always kept in the state of being engaged with the ratchet bar 51 by the elastic member. When the storage box 3 is moved upward, the pawl 52 can slide over the back of the ratchet 51. When the storage box 3 moves downward, the pawl 52 can be inserted into the tooth groove of the ratchet 51 by the elastic member, preventing the storage box 3 from moving downward.

The safety factor is greatly improved by the arrangement of the anti-falling component. Meanwhile, when the worker climbs up with the storage box 3, the storage box 3 can be fixed at the height every time the worker stops, so that the worker saves more labor.

Referring to fig. 3, the elastic member is a spring plate 53 disposed on both sides of the storage box 3. One end of the spring piece 53 is fixedly arranged on the storage box 3, and the other end of the spring piece 53 is abutted against the pawl 52 to push the pawl 52 to rotate towards the direction close to the ratchet bar 51.

Referring to fig. 4, in order to smoothly lower the storage box 3, threaded holes are formed at both sides of the storage box 3, and a limit bolt 6 is threadedly connected to the threaded holes. The pawl 52 is rotated so that the pawl 52 is separated from the ratchet 51, and then the limit bolt 6 is mounted on the storage box 3. At this time, the limit bolt 6 can be abutted against the pawl 52, so that the pawl 52 cannot approach the ratchet 51, and the storage box 3 can freely move up and down.

Referring to fig. 1 and 4, in order to conveniently lower the storage box 3 on the ground, a winding reel 71 is rotatably provided at the top end of the ladder body 1, and a connection cord 72 is wound around the winding reel 71. One end of the connecting rope 72 is fixed to the reel 71, and the other end of the connecting rope 72 is fixed to the hook 73. A hanging ring 74 matched with the hook 73 is fixedly arranged at the top end of the storage box 3. When the worker hangs the hook 73 on the hanging ring 74, the worker rotates the reel 71 to control the storage box 3 to descend to the ground along the guide post 21.

Referring to fig. 1, in order to facilitate the control of the rotation of the reel 71 by the worker, a crank 711 is fixedly provided on the reel 71, which improves the comfort of the worker.

The implementation principle of the embodiment of the application is as follows: the staff places the instrument that will need to carry in storage box 3, then carries shoulder belt 4 on one's body, climbs along cat ladder body 1. In the climbing process, the storage box 3 can be kept hovering at any position, so that the labor is saved for the workers, and the potential safety hazard is reduced.

When it is desired to carry the tool to the ground, the pawl 52 is rotated so that the pawl 52 and ratchet bar 51 are disengaged. The limit bolt 6 is then screwed onto the storage compartment 3 such that the limit bolt 6 abuts against the pawl 52, preventing the pawl 52 from contacting the ratchet bar 51. The hook 73 is hung on the hanging ring 74, the crank 711 is rotated, and the storage box 3 is lowered to the ground.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
