Description

Technical Field

[0001] This utility model relates to the field of elevator maintenance equipment technology, specifically to a safety monitoring and early warning device for a building construction elevator. Background Technology

[0002] Construction elevators, also known as construction lifts, are common vertical transportation machines used in building construction. They are divided into freight elevators and passenger / freight construction elevators, and come in various types. They are widely used in actual construction. A simple construction elevator consists of several parts, including a car, drive mechanism, standard sections, wall attachments, chassis, railings, and electrical system. It is a frequently used construction machine for carrying people and goods. Its unique box structure makes it both comfortable and safe to ride.

[0003] However, in the current operation of construction elevators, since people and goods enter the elevator at the same time, different goods need to be delivered to different floors each time the elevator ascends or descends. Each time the goods are moved to a floor, the elevator door must be leveled before the goods can be transported out of the elevator. However, when transporting heavy goods, the weight of the goods causes the elevator to shake when moving from the elevator to the floor. This shaking may cause other goods stacked in the elevator to become unstable, thus causing unnecessary injury to the passengers. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a solution to the problem that when transporting heavy cargo, the weight of the cargo causes the elevator to shake as it moves from floor to floor. This shaking may cause other goods placed in the elevator to become unstable, thus potentially causing unnecessary injury to passengers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A safety monitoring and early warning device for a construction elevator includes a car, a rotatable door panel on the side of the car near the door opening, a lifting assembly for opening and closing the door panel fixedly installed on the top of the car and on the side near the door panel, the lifting assembly driving the door panel to rotate, a positioning groove on one side of the door panel, a moving groove on the inner side wall of the positioning groove, and a buzzer assembly fixedly installed in the moving groove; it also includes several ground resistance blocks, which are fixedly installed between each floor, and the buzzer assembly abuts against the ground resistance blocks when the door panel is opened, closed and rotated.

[0006] Working principle: During construction, the freight elevator needs to transport goods to different construction floors each time. When the freight elevator stops at a floor, the operator activates the lifting component. The lifting component moves the door panel slowly and flattened into the floor plane until the door panel abuts against the floor. Then, the positioning groove installed on the door panel will engage with the ground resistance block on the floor. During the engagement process, the ground resistance block will abut against the buzzer component in the positioning groove until the buzzer component emits a warning sound. In this way, the staff can directly and effectively know that the construction elevator is aligned with the current floor and can work normally, ensuring that the car will not shake when the goods are transported out of the elevator.

[0007] The beneficial effects of this utility model are as follows: Compared with the aforementioned patent documents, this application document limits the elevator car to the floor level when it stops at a floor level, until the door panel abuts against the floor. Then, the positioning groove installed on the door panel engages with the ground block on the floor. During the engagement process, the ground block abuts against the buzzer component in the positioning groove until the buzzer component emits a warning sound. This method allows workers to directly and effectively know that the construction elevator is level with the current floor and can work normally, ensuring that the car will not shake when the cargo is transported out of the elevator.

[0010] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0011] like Figure 1 and Figure 2As shown, a safety monitoring and early warning device for a construction elevator includes a car 1. The car 1 has a rotatable door panel 2 near the door opening side. A lifting assembly for opening and closing the door panel 2 is fixedly installed on the top of the car 1 and near the door panel 2. The lifting assembly includes a first motor 6, a first rotating shaft 7, a positioning rod 8, a bearing 9, a blocking ring 10, a first belt 11, a second belt 12, and a fixing rod 13. The first rotating shaft 7 is fixedly installed on the top of the car 1 and at the output end of the first motor 6. The positioning rod 8 is fixedly installed on one side of the outer wall of the car 1. The bearing 9 is rotatably sleeved on the positioning rod 8. The blocking ring 10 is fixedly sleeved in the middle of the bearing 9. The two ends of the first belt 11 are rotatably sleeved on the first rotating shaft 7 and the bearing 9, respectively. The fixing rod 13 is fixedly installed on one side of the door panel 2, and the fixing rod 13 and the positioning rod 8 are located on the same side. The second belt 12... One end of the second belt 12 is fixedly installed on the bearing 9, and the other end of the second belt 12 is fixedly installed on the fixing rod 13. The lifting assembly can drive the door panel 2 to rotate. A positioning groove 3 is opened on one side of the door panel 2. A moving groove 4 is opened on the inner side wall of the positioning groove 3. A buzzer assembly is fixedly installed in the moving groove 4. The buzzer assembly includes a buzzer 16, two sliding plates 17 and two telescopic springs 18. A sliding groove 20 is opened on each side wall of the moving groove 4. Both ends of the two sliding plates 17 are slidably installed in the two sliding grooves 20, and two telescopic springs 18 are installed between the two sliding plates 17. The buzzer 16 is fixedly installed in the moving groove 4 and can abut against one of the sliding plates 17. It also includes several ground resistance blocks 5. Several ground resistance blocks 5 are fixedly installed between each floor. When the door panel 2 is opened and closed, the buzzer assembly abuts against the ground resistance blocks 5.

[0012] When the construction elevator needs to unload cargo into the construction floor, the construction workers first start the first motor 6. The first motor 6 drives the first shaft 7 to rotate, the first shaft 7 drives the first belt 11 to rotate, the first belt 11 drives the bearing 9 to rotate, and the bearing 9 drives the second belt 12 to rotate. The second belt 12 loosens the fixing rod 13, causing the fixing rod 13 to rotate continuously towards the floor until the door panel 2 abuts against the ground resistance block 5 on the floor. At this time, the operator will hear that when the door panel 2 is completely flush with the floor, the ground resistance block 5 located on the floor will first contact the positioning groove 3 on the door panel 2, and then the ground resistance block 5 will first abut against the sliding plate 17. Then the sliding plate 17 will not continuously... The two compression springs are squeezed together, and then the two compression springs continuously apply pressure to the other slide plate 17 until the slide plate 17 touches the button on the buzzer 16. At this time, the door panel 2 will emit a prompt sound, indicating that the door panel 2 is completely in contact with the ground. At this time, the construction workers can unload the cargo normally. When it is necessary to enter other floors, the construction workers restart the first motor 6. The first motor 6 drives the first shaft 7 to rotate, the first shaft 7 drives the first belt 11 to rotate, the first belt 11 drives the bearing 9 to rotate, the bearing 9 drives the second belt 12 to rotate, and the second belt 12 tightens the fixing rod 13 until the door panel 2 is in contact with the car 1, completing the unloading of cargo.

[0013] like Figure 1 and Figure 2 As shown, it also includes a rotating rod 14 and two reinforcing blocks 15. The two reinforcing blocks 15 are respectively located on the door opening side of the car 1 and close to the bottom of the car 1 and are integrally formed. The rotating rod 14 is fixedly inserted through the door panel 2 and the two ends of the rotating rod 14 are respectively installed in the two reinforcing blocks 15. The opening shape of the moving groove 4 is adapted to the ground resistance block 5. It also includes a handrail 19. The handrail 19 is fixedly installed on the door panel 2, and the side of the handrail 19 close to the interior of the car 1 is parallel until it contacts the floor.

[0014] The reinforcing block 15 allows the door panel 2 to open and close on one side of the car 1, and it can also support the weight of the door panel 2. The opening shape of the moving groove 4 can be adapted to the ground resistance block 5. The handrail 19 prevents construction workers from falling when the car shakes, reducing the risk in the construction elevator.

[0015] Working principle: When the construction elevator needs to unload cargo into the construction floor, the construction workers first start the first motor 6. The first motor 6 drives the first shaft 7 to rotate, the first shaft 7 drives the first belt 11 to rotate, the first belt 11 drives the bearing 9 to rotate, and the bearing 9 drives the second belt 12 to rotate. The second belt 12 loosens the fixing rod 13, causing the fixing rod 13 to rotate continuously towards the floor until the door panel 2 abuts against the ground resistance block 5 on the floor. At this time, the operator will hear that when the door panel 2 is completely flush with the floor, the ground resistance block 5 located on the floor will first contact the positioning groove 3 on the door panel 2, and then the ground resistance block 5 will first abut against the sliding plate 17. Then the sliding plate 17 will not continuously... The two compression springs are squeezed together, and then the two compression springs continuously apply pressure to the other slide plate 17 until the slide plate 17 touches the button on the buzzer 16. At this time, the door panel 2 will emit a prompt sound, indicating that the door panel 2 is completely in contact with the ground. At this time, the construction workers can unload the cargo normally. When it is necessary to enter other floors, the construction workers restart the first motor 6. The first motor 6 drives the first shaft 7 to rotate, the first shaft 7 drives the first belt 11 to rotate, the first belt 11 drives the bearing 9 to rotate, the bearing 9 drives the second belt 12 to rotate, and the second belt 12 tightens the fixing rod 13 until the door panel 2 is in contact with the car 1, completing the unloading of cargo.

[0016] The reinforcing block 15 allows the door panel 2 to open and close on one side of the car 1, and it can also support the weight of the door panel 2. The opening shape of the moving groove 4 can be adapted to the ground resistance block 5. The handrail 19 prevents construction workers from falling when the car shakes, reducing the risk in the construction elevator.
