[0001] This utility model relates to the technical field of fence door locks, specifically to fence door locks for construction hoists. Background Technology

[0002] Construction hoists play a crucial role in the vertical transportation of personnel and goods during construction, making their safety paramount. The bottom railing, a vital safety feature, isolates the hoist from the surrounding area, preventing unauthorized personnel from entering its operating zone. The railing lock is the key device ensuring the effectiveness of this protective function. Existing construction hoist railing locks suffer from several problems. Some locks are complex in structure, difficult to manufacture and install, and costly; some locks are easily damaged by impacts due to their protruding outer parts, rendering them unable to lock properly; others have poor stability during use, prone to accidental opening, seriously threatening the lives of construction workers and the normal operation of construction equipment; furthermore, operators need to spend considerable time and effort opening and closing the locks, which impacts construction efficiency. Therefore, a new construction hoist railing lock is needed to address these issues. Utility Model Content

[0022] Example

[0023] Please see Figures 1-5 The construction hoist fence door lock includes a fence frame 1, a switch door 2, and a hoisting basket 3. An entrance / exit 4 is provided on one side of the fence frame 1. The switch door 2 is hinged to the entrance / exit 4 on one side, with the hinge located outside the fence frame 1. The hoisting basket 3 is located inside the fence frame 1. It also includes:

[0024] The door lock assembly is used to lock the door 2. The door lock assembly includes a locking rod 5, a rotating shaft 6, a rotating plate 7, and a pressing plate 8. A first groove 9 is provided on one side of the entrance / exit 4, and a second groove 10 is provided on one side of the door 2. The first groove 9 and the second groove 10 form a fan-shaped structure. The locking rod 5 is laterally positioned within the first groove 9 and the second groove 10. One end of the rotating rod is connected to one side of the locking rod 5. A rotating hole is provided in the first groove 9, and the rotating rod is rotatably connected to the rotating hole. One end of the rotating plate 7 is connected to the other end of the rotating shaft 6. The top of the pressing plate 8... The bottom of the pressing plate 8 is slidably connected to the top of the rotating plate 7, and a limit mechanism is provided on the fence frame 1. The limit mechanism is used to limit the locking rod 5 so that the locking rod 5 can be disengaged from the second groove 10 only after the lifting basket 3 has descended to the ground. The lifting basket 3 usually uses a track for lifting during the lifting process. By using a door lock assembly composed of locking rod 5, rotating shaft 6, rotating plate 7 and pressing plate 8, combined with the hinged design of fence frame 1 and opening / closing door 2, the overall structure is simpler than the existing complex door lock. By forming a fan-shaped structure with the first groove 9 and the second groove 10, and allowing the locking rod 5 to slide within it, the number of parts and assembly difficulty are reduced, manufacturing and installation costs are lowered, and production efficiency is improved. The design of this door lock assembly places the protruding part inside the fence frame 1. Compared with existing door locks where the protruding part is on the outside and is easily damaged by bumps, this effectively avoids the impact of external collisions on the door lock, reduces the risk of the door lock failing to lock properly due to external force damage, improves the reliability and service life of the door lock, and ensures the effectiveness of the fence protection function. The setting of the limiting mechanism ensures that the locking rod 5 can only disengage from the second groove 10 after the lifting basket 3 descends to the ground, and 10 avoids the door lock from being accidentally opened due to unexpected factors during the operation of the elevator. This design provides more reliable safety for construction personnel and equipment, greatly reducing the probability of safety accidents and ensuring the safety of construction personnel and the normal operation of construction equipment. The pressing plate 8 is connected to the lifting basket 3. When the lifting basket 3 descends, the pressing plate 8 can drive the rotating plate 7 to rotate, thereby causing the locking rod 5 to slide and unlock. When the lifting basket 3 rises, the pressing plate 8 rises, and the locking rod 5 slides back into the second groove 10 under the action of gravity to lock the door 2. The operator does not need to spend too much time and effort to manually operate the door lock, which simplifies the operation process of opening and closing the door 2, improves construction efficiency, and saves construction time and labor costs.

[0025] Please see Figures 1-5The limiting mechanism includes a limiting plate 11, a mounting frame 12, a connecting rod 13, a spring 14, two sets of driving components 15, and two sets of push plates 16. A sliding hole is provided in the first groove 9, and the sliding hole is located above the locking rod 5. The outer wall of the limiting plate 11 is slidably connected to the sliding hole. The mounting frame 12 is mounted on the fence frame 1. The connecting rod 13 is slidably connected to the mounting frame 12. One end of the connecting rod 13 is connected to one end of the limiting plate 11. The spring 14 is fitted onto the outer wall of the connecting rod 13. Both ends of the spring 14 are connected to the limiting plate 11 and the mounting frame 12, respectively. The two sets of driving components 15 are connected to the other end of the connecting rod 13. Both sets of push plates 16 are connected to the lifting basket 3. Next, both sets of push plates 16 and both sets of drive components 15 are provided with inclined surfaces 17. The inclined surfaces 17 on the two sets of push plates 16 slide and fit against the inclined surfaces 17 on the two sets of drive components 15 respectively. Through the cooperation of components such as the limiting plate 11, mounting frame 12, connecting rod 13, spring 14, drive component 15 and push plate 16, and utilizing the sliding fit principle of the inclined surfaces 17, the pressing plate 8 only contacts the rotating plate 7 after the limiting plate 11 has completely exited the first groove 9. This ensures that the limiting plate 11 can only release the locking rod 5 and disengage from the second groove 10 when the lifting basket 3 is about to descend to the ground. This design further enhances the security of the door lock, ensuring that the fence gate can only be opened when the lift has safely stopped on the ground, effectively preventing safety accidents caused by premature opening of the fence gate due to misoperation or other unexpected situations.

[0026] Please see Figures 1-5 A roller 18 is provided at the bottom of the pressing plate 8, and the roller 18 is rotatably connected to the top of the rotating plate 7. This roller 18 transforms the sliding friction between the pressing plate 8 and the rotating plate 7 into rolling friction, greatly reducing the frictional force between them. During operation, the pressing plate 8 drives the rotating plate 7 to rotate more smoothly, reducing component wear, extending the service life of the door lock, and making opening and closing the door 2 lock easier and less strenuous.

[0027] Please see Figures 1-5 A seeding block 19 is provided at one end of the locking rod 5 located in the second groove 10; a counterweight is provided at one end of the locking rod 5 located in the second groove 10. The counterweight can increase the gravity of the locking rod 5, making the locking rod 5 more stable during movement. This allows the locking rod 5 to enter the second groove 10 after the lifting basket 3 rises due to gravity, locking the door 2. This further improves the stability of the door lock, ensuring that the door lock can reliably lock the door 2 and prevent accidental opening.

[0028] Please see Figure 1A door handle 20 is provided on the outside of the switch door 2. The door handle 20 on the outside of the switch door 2 provides a convenient point of force for the operator, making it easier for the operator to open and close the switch door 2, making the operation of the switch door 2 more convenient and labor-saving, and further improving the user experience and construction efficiency during the construction process.

[0029] In summary, the construction hoist fence door lock, when in use, employs a door lock assembly consisting of a locking rod 5, a rotating shaft 6, a rotating plate 7, and a pressing plate 8, combined with the hinged design of the fence frame 1 and the opening / closing door 2. Compared to existing door locks with complex structures, the overall structure is simpler. By forming a fan-shaped structure with the first groove 9 and the second groove 10, and allowing the locking rod 5 to slide within it, the number of parts and assembly difficulty are reduced, manufacturing and installation costs are lowered, and production efficiency is improved. The design of this door lock assembly places the protruding part inside the fence frame 1, which, compared to existing door locks where the protruding part is on the outside and easily damaged by bumps, effectively avoids the impact of external collisions on the door lock, reduces the risk of the door lock failing to lock properly due to external force damage, improves the reliability and service life of the door lock, and ensures the effectiveness of the fence protection function. The setting of the limit mechanism ensures that the locking rod 5 can only disengage from the second groove 10 after the lifting basket 3 descends to the ground, preventing the door lock from being accidentally opened due to unexpected factors during the operation of the hoist. This design provides more reliable safety for construction personnel and equipment, greatly reducing the probability of safety accidents and ensuring the safety of construction personnel and the normal operation of construction equipment. The pressing plate 8 is connected to the lifting basket 3. When the lifting basket 3 descends, the pressing plate 8 can drive the rotating plate 7 to rotate, thereby causing the locking rod 5 to slide and unlock. When the lifting basket 3 rises, the pressing plate 8 rises, and the locking rod 5 slides back into the second groove 10 under the action of gravity to lock the door 2. The operator does not need to spend too much time and effort to manually operate the door lock, which simplifies the operation process of opening and closing the door 2, improves construction efficiency, and saves construction time and labor costs.

[0030] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
