Description

Technical Field

[0001] This invention relates to the field of elevator cable accessories technology, and in particular to an elevator cable connection structure. Background Technology

[0002] Elevator cables are a crucial component of elevator systems, primarily used to connect the elevator car to the control system, transmitting power, signals, and data. Their connection structures are widely used in various types of vertical elevators, including residential buildings, commercial buildings, hospitals, and subway stations. In these environments, elevator cables need to repeatedly bend and stretch as the car moves up and down, while ensuring a stable power supply and accurate signal transmission. This places high demands on the cable's flexibility, abrasion resistance, and anti-interference capabilities.

[0003] Currently, when elevator cables need to be spliced ​​together, they are usually joined by wrapping insulating tape to make electrical contact between the two elevator cables. This connection method has poor strength, and the elevator cables are prone to breaking during elevator operation, which cannot meet the dynamic operation requirements of the elevator and can easily lead to elevator safety accidents, thereby affecting the safety of passengers. In order to ensure the stable operation of the elevator and improve the safety and reliability of the elevator cable splice, it is necessary to design a reliable elevator cable splicing structure. Summary of the Invention

[0004] The purpose of this invention is to provide an elevator cable splicing structure that can ensure the stable operation of the elevator and improve the safety and reliability of the elevator cable splicing.

[0005] To achieve the above objectives, the technical solution proposed by this invention is as follows:

[0006] An elevator cable docking structure is wrapped around an elevator cable. It is characterized in that it includes a waterproof layer, a locking layer and a rubber ring. The rubber ring is wrapped around the elevator cable, the locking layer is wrapped around the rubber ring, and the waterproof layer is wrapped around the locking layer; the locking layer is oval in shape and includes a plurality of straight splicing plates, a plurality of connecting plates and two arc-shaped splicing plates. The plurality of straight splicing plates are respectively arranged at the top and bottom of the elevator cable, and the two arc-shaped splicing plates are respectively arranged on both sides of the elevator cable. The straight splicing plates are connected to each other and the splicing plates are connected to the arc-shaped plates through connecting plates; a first rotating groove is provided on one side of each of the plurality of straight splicing plates and the two arc-shaped splicing plates. One side of the connecting plate is located in the first rotating groove and is rotatably connected to the corresponding straight splicing plate and arc-shaped splicing plate. A second rotating groove and a first jack are provided on the other side of each of the plurality of straight splicing plates and the two arc-shaped splicing plates. A second jack is provided on the other side of the connecting plate, and the other side of the connecting plate is located in the second rotating groove. The first jack and the second jack are coaxially arranged. A plug rod is movably arranged on the other side of the connecting plate and is inserted into the first jack and the second jack. The other side of the connecting plate is rotatably connected to the corresponding straight splicing plate and arc-shaped splicing plate; a through hole in the shape of a Chinese character 'zhong' is provided on the side wall of the straight splicing plate and the arc-shaped splicing plate close to the second rotating groove, and the diameter of the through hole on the side close to the second rotating groove is smaller than the diameter on the side far from the second rotating groove. A spring is provided in the middle of the through hole. The through hole and the first jack are coaxial. The plug rod passes through the through hole and one end is located in the through hole.

[0007] This elevator cable docking structure is applicable to elevator cables with an oval cross-section. When used for splicing elevator cables, two rubber rings are sleeved on the outer surfaces of the insulating layers of the two elevator cables close to the splicing position. The locking layer is wrapped around the splicing position of the elevator cables and the two rubber rings. Finally, a waterproof layer is provided on the locking layer to complete the splicing; when setting the locking layer, the inner surface circumference of the locking layer is greater than the outer surface circumference of the elevator cable. The upper and lower sides of the elevator cable are wrapped by straight splicing plates, and the left and right sides of the elevator cable are wrapped by arc-shaped splicing plates. When one side of the connecting plate is connected to one side of the straight splicing plate and the arc-shaped splicing plate, one side of the connecting plate is located in the first rotating groove and is rotatably connected to the corresponding straight splicing plate and arc-shaped splicing plate. When the other side of the connecting plate is connected to the other side of the straight splicing plate and the arc-shaped splicing plate, the plug rod is inserted into the first jack and the second jack, so that the other side of the connecting plate is rotatably connected to the other side of the straight splicing plate and the arc-shaped splicing plate. When all components of the locking layer are made of steel, it has reliable strength. When the outer surface circumference of the elevator cable is too large or too small, it can be adjusted by reducing or increasing the number of straight splicing plates. When the thickness of the elevator cable is greater than the diameter of the arc-shaped splicing plate, the straight splicing plate close to the arc-shaped splicing plate can be rotated to an inclined position so that the locking layer can completely wrap the elevator cable. The rubber ring and the waterproof layer are elastic sealing materials and can be freely adjusted in size.

[0008] Preferably, a plurality of fixing holes are provided in the middle of the straight splicing plate, and a plurality of fixing rings are provided on the side of the straight splicing plate close to the elevator cable. The top of the fixing ring passes through the two fixing holes.

[0009] Preferably, the straight splicing plate has multiple straight clamping plates on both sides of multiple fixing rings, the ends of the straight clamping plates extend to both sides of the straight splicing plate, and two rubber rings are provided, which respectively abut against the multiple straight clamping plates on both sides of the fixing rings.

[0010] Preferably, the inner side of the arc-shaped splicing plate is provided with an arc-shaped clamping plate corresponding to the straight clamping plate, and the ends of the arc-shaped clamping plate are flush with the ends of the straight clamping plate.

[0011] Preferably, one end of the insertion rod is provided with a protruding rod, the middle of the through hole is provided with a fan-shaped groove to accommodate the rotation of the protruding rod, and a receiving groove to accommodate the protruding rod is provided near the outer side of the through hole.

[0012] Preferably, a plurality of first rotating cylinders are fixedly arranged at intervals in the first rotating groove, and a plurality of first empty grooves corresponding to the first rotating cylinders are provided on one side of the connecting plate.

[0013] Preferably, a plurality of second rotating cylinders are fixedly arranged at intervals in the second rotating groove, and a plurality of second empty grooves corresponding to the second rotating cylinders are provided on the other side of the connecting plate.

[0014] Preferably, the waterproof layer is made of waterproof tape wrapped around and locking the layer.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. By setting a locking layer, the splicing position of the elevator cable group is bound together with the fixing holes on the straight splicing plate using fixing rings. The straight and curved clamps on the straight and curved splicing plates on the locking layer can squeeze the rubber rings fitted on the outer surface of the elevator cable. Thus, the connection of the elevator cable joint and the two elevator cables can be connected through the locking layer, thereby ensuring the stable operation of the elevator and improving the safety and reliability of the elevator cable splicing.

[0017] 2. The locking layer is constructed by splicing multiple straight splicing plates, multiple connecting plates, and two arc-shaped splicing plates, allowing for size adjustment. When the circumference of the elevator cable's outer surface is too large or too small, the number of straight splicing plates can be adjusted by reducing or increasing the number of plates. When the thickness of the elevator cable is greater than the diameter of the arc-shaped splicing plate, the straight splicing plate near the arc-shaped splicing plate can be rotated to an inclined position, ensuring that the locking layer completely covers the elevator cable. Furthermore, the rubber ring and waterproof layer are made of elastic sealing materials, allowing for free size adjustment, thereby increasing the applicability of this docking structure.

[0018] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
