Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a prefabricated elevator connection device. Background Technology

[0002] Currently, most older residential communities use overhead power lines for power supply. Low-voltage overhead power lines are horizontally installed along the crossarms on the side walls of doorways, connecting to the power supply for subsequent users. Elevators are installed on the outside of the stairwell walls, with the elevator shaft installed vertically from the first floor to the top floor. This inevitably leads to intersections with the low-voltage overhead power lines installed along the walls, causing path conflicts. To ensure safe power supply and reliable elevator operation, sufficient safety distance must be maintained at the intersections. Utility Model Content

[0034] Building structure 10, connecting corridor 20, elevator shaft structure 30 and soft copper cable 40; both building structure 10 and elevator shaft structure 30 are connected to connecting corridor 20.

[0035] A power line 11 is installed on the outside of the building structure 10, and the power line 11 is used to supply power to users;

[0036] The connecting corridor 20 is located between the building structure 10 and the elevator shaft structure 30, and is used to connect passages between different floors;

[0037] The elevator shaft structure 30 is located on the outside of the building structure 10, extending vertically from the first floor to the top floor, and serves as the elevator's operating passage; the elevator shaft structure 30 intersects with the power line 11.

[0038] The soft copper cable 40 is used to make an electrical connection at the intersection of the elevator shaft structure 30 and the power line 11, and passes through the inner wall of the connecting corridor 20 to connect with the power line 11.

[0039] Specifically, the connecting corridor, as a passageway connecting different floors, not only facilitates the passage of users, but also makes the connection between the elevator shaft structure 30 and the building structure 10 more compact and efficient; the elevator shaft structure 30 extends vertically from the first floor to the top floor, making full use of the building's height space and providing sufficient vertical passage for elevator operation; the flexible copper cable 40, as an electrical connection element, has good conductivity and flexibility, can adapt to the relative movement between the elevator shaft structure 30 and the power line 11, and at the same time provides necessary electrical isolation and protection to prevent electrical faults from affecting elevator operation.

[0040] The prefabricated elevator connection device provided in this embodiment includes a building structure 10, a connecting corridor 20, an elevator shaft structure 30, and a flexible copper cable 40. A power line 11 is installed on the outside of the building structure 10, supplying power to users. The connecting corridor 20 is located between the building structure 10 and the elevator shaft structure 30, serving as a passageway connecting different floors. The elevator shaft structure 30 is located on the outside of the building structure 10, extending vertically from the first floor to the top floor, serving as the elevator's operating passageway. The elevator shaft structure 30 and the power line 11 intersect. The flexible copper cable 40 is electrically connected at the intersection of the elevator shaft structure 30 and the power line 11, and passes through the floor slab of the connecting corridor 20 to connect with the power line 11. By installing a flexible copper cable 40 at the intersection of the elevator shaft structure 30 and the power line 11 for electrical connection, the risk of power outages caused by interruption or poor contact of the power line 11 can be reduced, the stability of power supply can be improved, and the normal operation of the elevator and the safety of users can be guaranteed.

[0041] Optionally, the prefabricated elevator connection device also includes:

[0042] Branch glove 50, used to connect soft copper cable 40 and power line 11.

[0043] Specifically, the branch glove 50 is made of a high-insulation material, which can form a double insulation barrier at the connection between the soft copper cable 40 and the power line 11, effectively isolating the live parts from the external environment and avoiding the risk of leakage caused by moisture, dust or external damage.

[0044] Optionally, the prefabricated elevator connection device also includes:

[0045] Sleeve 60; Sleeve 50 is pre-embedded at the intersection of the elevator corridor structure and the power line 11.

[0046] Specifically, the bushing 50, as a rigid protective layer, can withstand huge external impacts, preventing damage or breakage of the insulation layer of the power line 11, and solving the problems of interference, maintenance and safety of cross-line in the elevator electrical system.

[0047] Optionally, a soft copper cable 40 passes through a conduit 60 to maintain a safe distance between the elevator shaft structure 30 and the power line 11.

[0048] Specifically, within the elevator shaft structure 30, the insulation between the power line 11 and the control signal line may fail due to vibration, aging, or external damage. The soft copper cable 40 passes through the sleeve 60 to form a rigid isolation layer, which can maintain the minimum safe distance between the two and avoid short circuits or arcing failures caused by contact.

[0049] Optionally, the prefabricated elevator connection device also includes:

[0050] Insulation layer, the insulation layer wraps around the soft copper cable 40, to prevent leakage or short circuit.

[0051] Specifically, the insulation layer can withstand high voltage, preventing arc discharge when the soft copper cable 40 comes into contact with the sleeve 60, thus preventing electric shock or fire risks; the insulation layer can also absorb external impacts, preventing the soft copper cable 40 from breaking or deforming, thereby ensuring the reliability of the electrical connection.

[0052] Optional, the cross-sectional area of ​​the soft copper cable 40 is 10-70mm². 2 .

[0053] Among them, the soft copper cable 40 uses materials with strong insulation and good flame retardant properties.

[0054] Specifically, soft copper cables 40, due to their good flexibility, can be bent into the required shape and are suitable for smaller cross-sectional areas (such as 10mm²). 2 It makes wiring easier in the confined space of the shaft, reducing the risk of mechanical damage.

[0055] Optional, the branch gloves 50 include:

[0056] Insulating housing, used to protect internal electrical connection components;

[0057] Electrical connection terminals are located at both ends of the branch glove 50 and are used to connect the soft copper cable 40 and the power line 11.

[0058] Specifically, the insulating housing is a key line of defense for protecting the internal electrical connection components. The combined design of the insulating housing and electrical connection terminals effectively isolates the electrical connection points from the external environment, avoiding the risk of electric shock. At the same time, the insulating housing and electrical connection terminals reduce the risk of system downtime caused by electrical faults.

[0059] Optionally, the electrical connection terminals are connected to the soft copper cable 40 and the power line 11 by crimping or clamping.

[0060] Specifically, the crimping method has a large contact area and low resistance, which can reduce heat generation or sparks caused by poor contact.

[0061] Optionally, the power line 11 is a four-wire power line, which is connected to the soft copper cable 40 via a branch glove 50.

[0062] A four-wire power line includes three-phase power lines (L1, L2, L3) and a neutral line (N).

[0063] Specifically, the four-wire power line is connected to the soft copper cable 40 through the branch glove 50, which can achieve rapid branching and insulation protection.

[0064] Optionally, the prefabricated elevator connection device also includes:

[0065] The grounding device is connected to the bushing 60 and is used to introduce leakage current into the earth.

[0066] Specifically, the grounding device is the safety baseline of the electrical system. By diverting leakage current to the earth, it prevents electric shock to personnel or damage to equipment.
