Description

Technical Field

[0001] The invention relates to the technical field of elevators, and in particular to a warning-type floor-changing elevator for preventing hidden dangers of standing positions. Background Art

[0002] During the construction process, the elevator is an indispensable equipment for vertical transportation of personnel and materials. When the existing elevator is in use, the elevator is installed on a guide frame, and then the gear and rack are meshed to make the elevator rise and fall in the guide frame to vertically transport personnel and materials. When personnel and materials enter the elevator, the staff needs to push the moving door upwards, and then pull down the moving door to close the elevator after entering. Since the moving door can still be pushed up and opened from the inside of the elevator after it is closed, the moving door may be opened by mistake during the process of the elevator rising and falling, and when the staff closes the moving door, the door may not be closed tightly, resulting in a high safety hazard.

[0003] Therefore, a warning type floor-changing elevator has been developed to prevent hidden dangers in the position by pressing down the moving door during the ascent and descent of the elevator to avoid safety accidents caused by the moving door not being closed or being opened by mistake. Summary of the invention

[0004] In order to overcome the disadvantages that the moving door may be opened by mistake during the ascent and descent of the elevator, and the moving door may not be closed tightly when the staff closes it, resulting in a high safety hazard, the present invention provides a warning type floor-changing elevator that can press down the moving door during the ascent and descent of the elevator to avoid safety accidents caused by the moving door not being closed tightly or being opened by mistake, thereby preventing standing hazards.

[0005] The technical implementation scheme of the present invention is: a warning-type floor-changing elevator for preventing standing hazards, including an elevator, a movable door and a locking mechanism. The movable doors are slidably connected on both sides of the elevator, and the elevator is provided with a locking mechanism that can lock the movable door.

[0006] Optionally, ventilation holes are provided at both the front and rear parts of the lift.

A rack is connected to the sides of the front and rear parts of the movable door that are close to each other, the upper sides of the left and right parts of the elevator are connected to the fixed frame, the lower part of the fixed frame is rotatably connected to the first connecting column, the front side of the first connecting column is connected to the roller, the middle and rear parts of the first connecting column are connected to the first gear, the middle part of the fixed frame is slidably connected to the sliding column, the front and rear sides of the sliding column are rotatably connected to the second gear, the second gear is meshed with the adjacent first gear, the upper part of the fixed frame is rotatably connected to the second connecting column, the front and rear sides of the second connecting column are connected to the third gear, the third gear is meshed with the adjacent second gear, and the upper part of the fixed frame is rotatably connected to the third connecting column. The connecting column and the third connecting column are connected to connecting plates on both sides, and a plurality of guide teeth are slidably connected to the connecting plates, and the guide teeth are meshed with adjacent third gears, and the guide teeth are meshed with adjacent racks. A plurality of first springs are connected between the guide teeth and the connected connecting plates. When the elevator moves, the roller moves on the guide rail frame, so that the first connecting column rotates, driving the first gear to rotate and mesh with the second gear, so that the second gear meshes with the third gear. The second connecting column rotates, and the guide teeth on the connecting plate mesh with the third gear through the force of the first spring. The third connecting column rotates, and the guide teeth rotate and mesh with the rack, pushing the rack to move downward. When the elevator moves in the opposite direction, the sliding column moves, so that the second gear moves and meshes with the guide teeth, so that the first gear can push the rack to move downward regardless of forward or reverse rotation.

[0009] Optionally, an adjustment mechanism is also included, which includes a pressure plate, a first shell, a second shell, a motor, a screw, a weight block and fixing screws. A pressure plate is connected to the inner side of the lower part of the elevator, and the lower side of the elevator is connected to the first shell. The lower side of the first shell is detachably connected to the second shell by multiple fixing screws. Two front and rear motors are connected to the left side of the middle of the first shell, and two left and right motors are also connected to the front side of the middle of the second shell. The motor is electrically connected to the pressure plate, and screws are connected to the motor output shafts. The upper screw is rotatably connected to the first shell, and the lower screw is rotatably connected to the second shell. Weight blocks are threadedly connected to the screws, and the upper weight block is slidably connected to the first shell, and the lower weight block is slidably connected to the second shell. The second shell is installed on the first shell by fixing screws. After personnel and materials enter the elevator, the pressure plate senses the pressure distribution.

The lower sides of the left and right parts of the second shell are connected to the fixed connecting frame, and the middle part of the fixed connecting frame is rotatably connected to the front and rear rotating frames. A plurality of torsion springs are connected between the rotating frames and the connected fixed connecting frames. The lower sides of the front and rear parts of the fixed connecting frame are connected to the guide plates through damping sliding. A plurality of third springs are connected between the guide plates and the connected fixed connecting frames. When the elevator descends to the ground, the rotating frame first contacts the ground and rotates, and the torsion spring is deformed, so that the rotating frame pushes the guide plate to move upward, and the impact and vibration are decelerated by the action force of the third spring.

[0013] Optionally, a display mechanism is also included, which includes a connecting and fixing plate and a display screen. The connecting and fixing plate is connected to the inner side of the rear part of the elevator, and the connecting and fixing plate is connected to the display screen, so that the display screen on the connecting and fixing plate plays a safety specification video.

[0014] Optionally, a prompt mechanism is also included, which includes a camera and a prompt speaker. The camera is connected to the inner side of the upper part of the elevator, and the prompt speaker is connected to the inner side of the rear part of the elevator. The prompt speaker is located above the connecting fixed plate. When the elevator rises or descends to the designated position, the prompt speaker prompts the staff and the camera monitors the internal situation of the elevator.

[0015] Compared with the prior art, the present invention has the following advantages: 1. The present invention moves the roller on the guide rail frame to rotate the first connecting column, driving the first gear to rotate and mesh with the second gear, so that the second gear meshes with the third gear. The action of the first spring causes the guide teeth on the connecting plate to mesh with the third gear. When the guide teeth rotate, they mesh with the rack, pushing the rack to move downward, thereby achieving the effect of pressing down the moving door during the ascent and descent of the elevator, avoiding safety accidents caused by the moving door not being closed or being opened by mistake.

[0016] 2. The present invention installs the second shell on the first shell by fixing screws. After people and materials enter the elevator, the pressure plate senses the pressure distribution. When the pressure plate senses that the pressure distribution is uneven, the motor is started to drive the screw to rotate, so that the weight block moves to adjust the pressure distribution, thereby achieving the effect of adjusting the pressure distribution in the elevator according to the positions of people and materials in the elevator, avoiding safety hazards caused by uneven pressure distribution in the elevator.

[0017] 3. The present invention drives the connecting bracket to rotate while the first connecting column rotates. The guide knocking column knocks the elevator under the action of the second spring, thereby achieving the effect of issuing a warning sound to remind internal personnel during the ascent and descent of the elevator.

[0018] 4. When the elevator of the present invention descends to the ground, the rotating frame first contacts the ground and rotates, and the torsion spring is deformed, so that the rotating frame pushes the guide plate to move upward, and the impact and vibration are reduced by the action force of the third spring, thereby achieving the effect of buffering and shock absorbing the elevator and improving the operating stability of the elevator.

[0019] 5. The present invention achieves the effect of improving the safety awareness of the staff by playing the safety standard video on the display screen connected to the fixed plate.

[0020] 6. The present invention enables the reminder speaker to remind the staff when the elevator rises or descends to the specified position, and the camera monitors the internal situation of the elevator, thereby achieving the effect of being able to remind the staff of the elevator's rising or falling situation and facilitating the staff to perform the next step of operation.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] A warning type floor-changing elevator to prevent hidden dangers of standing positions, such as Figure 1-Figure 10 As shown, it includes a lift 1, a moving door 2 and a locking mechanism 3. The moving doors 2 are slidably connected to the left and right sides of the lift 1. Air holes are opened at the front and back of the lift 1 to facilitate air circulation. The moving doors 2 are provided with handles for easy pulling. The lift 1 is provided with a locking mechanism 3.

[0034] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the positioning mechanism 3 includes a rack 30, a fixed frame 31, a first connecting column 32, a roller 33, a first gear 34, a sliding column 35, a second gear 36, a second connecting column 37, a third gear 38, a third connecting column 39, a connecting plate 310, a guide tooth 311 and a first spring 312.

When the elevator 1 stops moving and the moving door 2 needs to be opened, the guide tooth 311 can be squeezed by the rack 30, thereby pressing down the moving door 2 during the ascent and descent of the elevator 1 to avoid safety accidents caused by the moving door 2 not being closed tightly or being opened by mistake.

[0036] like Figure 1 , Figure 6 and Figure 7 As shown, it also includes an adjustment mechanism 4, which includes a pressure plate 40, a first shell 41, a second shell 42, a motor 43, a screw 44, a weight block 45 and a fixing screw 46. The pressure plate 40 is connected to the inner side of the lower part of the lift 1, and the first shell 41 is connected to the lower side of the lift 1. The lower side of the first shell 41 is detachably connected to the second shell 42 through four fixing screws 46. The fixing screws 46 are all provided with knobs for easy use. The front and rear motors 43 are connected to the left side of the middle part of the first shell 41, and the left and right motors 43 are also connected to the front side of the middle part of the second shell 42. The motor 43 is electrically connected to the pressure plate 40, and the output shafts of the motors 43 are connected to the screw rods 44.

[0044] like Figure 1 and Fig.10 As shown, it also includes a prompt mechanism 8, which includes a camera 80 and a prompt speaker 81. The camera 80 is connected to the inner side of the upper part of the elevator 1, and the prompt speaker 81 is connected to the inner side of the rear part of the elevator 1. The prompt speaker 81 is located above the connecting fixed plate 70.

[0045] By using the prompt mechanism 8 of the present device, the lifting and lowering status of the elevator 1 can be prompted. When the elevator 1 rises or descends to the specified position, the prompt speaker 81 prompts the staff, and the camera 80 monitors the internal situation of the elevator 1, thereby prompting the lifting and lowering status of the elevator 1 and facilitating the staff to perform the next step of operation.
