Description

Technical Field

[0001] This invention belongs to the field of elevator technology, and particularly relates to a car system for a steel belt elevator. Background Technology

[0002] In recent years, with the development of elevator technology, the steel wire rope of elevator traction drive has evolved into steel belt drive, which has a significantly longer lifespan than traditional steel wire rope; it is lighter in weight, much lighter than traditional steel wire rope; it is more robust and durable, and safer, providing passengers with greater safety protection; and it can effectively reduce vibration and noise.

[0003] In existing technologies, elevator car bottom structures vary widely and are complex in design. The car bottom is equipped with shock-absorbing blocks, and a car support is installed below the shock-absorbing blocks to reduce the impact of the drive unit on the car vibration. However, the car support is large in size and occupies a large amount of shaft space, so a deep pit and shaft are generally required for its installation. In order to work with the shock-absorbing blocks on the car bottom, a buffer component is also installed on the car top. The top beam can only be installed above the buffer component, and there is a large gap between the top beam and the car top. Therefore, the entire car frame occupies a large amount of shaft space, which increases the requirements for shaft space and also increases the cost of the elevator.

[0004] Chinese utility model patent CN 206126599 U discloses a steel-belt elevator car bottom structure, including a car support, a car bottom, and vertical beams arranged perpendicularly to the car support on both sides. The key feature is the presence of a shock-absorbing pad between the car support and the car bottom, a safety clamp on the inner side of the lower end of the vertical beams, guide shoes below the safety clamp, and car bottom wheels inside the car support. This design inherits the balanced force distribution of conventional elevator car bottoms, reduces the height occupied by the shock-absorbing pads, simplifies and strengthens the car bottom reinforcing ribs, cleverly utilizes the space between the vertical beams and the car support to accommodate the safety clamp body, and does not affect the replacement of the safety clamp later in the project. The guide shoes are embedded in the vertical beams and cooperate with the guide rails, reducing the elevator's pit depth requirements. Although this design reduces the elevator's shaft depth requirements to some extent, the presence of shock-absorbing blocks and a large-volume car support still means that the shaft depth requirement remains high. Summary of the Invention

[0005] In view of the problems existing in the prior art, the present invention provides a car system for a steel belt elevator. The technical problem to be solved by the present invention is how to reduce the space occupied by the car system in the hoistway.

[0006] To solve the above-mentioned technical problems, the present invention provides a car system for a steel belt elevator, including a car and a car frame, wherein the car frame is disposed outside the car and connected to the car;

[0007] The car includes a car top panel, a car bottom panel, and side walls. The car top panel and the car bottom panel are connected by the side walls, and the car top panel, car bottom panel, and side walls form a cavity structure.

[0008] The car frame includes a car top assembly, a car bottom assembly, and columns. The car top assembly is attached to the upper surface of the car top plate, the car bottom assembly is attached to the lower surface of the car bottom plate, and the side of the car bottom assembly is connected to the side of the car top assembly through columns. The columns are perpendicular to the car top plate.

[0009] The car roof assembly includes a top beam, an upper boot assembly, and a car roof side panel. The top beam is attached to the upper surface of the car roof panel, the axis of the top beam is perpendicular to the axis of the upright, the end of the top beam is connected to the car roof side panel, the car roof side panel is connected to the edge of the car roof panel, the upper boot assembly is connected to the upper surface of the top beam, and the upright is connected to the side of the car roof side panel.

[0010] Furthermore, the upper shoe assembly includes an upper guide shoe plate, an upper guide shoe, and a square oil cup. The upper guide shoe plate is connected to the upper end of the top beam, the upper guide shoe is connected to the upper surface of the upper guide shoe plate, and the square oil cup is connected above the upper guide shoe. The square oil cup is a lubrication device that not only improves the reliability of the elevator guide rail's guidance but also extends the service life of the guide rail. The elevator oil cup reduces friction between the guide shoe liner and the guide rail by lubricating the guide shoe, thereby improving the elevator's operational stability.

[0011] Furthermore, a car top inspection box is connected to the upper surface of the top beam. This facilitates safe, reliable, and convenient elevator maintenance by maintenance personnel. The electrical components installed in the car top inspection box generally include buttons for controlling the elevator's slow up and slow down movement, inching door opening and closing buttons, an emergency stop button, and a switch for switching between normal car top operation and maintenance operation.

[0012] Furthermore, the top beam is made of channel steel.

[0013] Furthermore, the car floor assembly includes reinforcing ribs, wheel seat assemblies, and car floor side panels. The car floor side panels are connected to the edge of the car floor plate, the reinforcing ribs are attached to the lower surface of the car floor plate, the wheel seat assemblies are attached to the lower surface of the car floor plate, and the ends of the wheel seat assemblies are connected to the pillars.

[0014] Furthermore, the wheel assembly includes a car bottom wheel and a car bottom wheel seat. The car bottom wheel is connected to both ends of the car bottom wheel seat via a rotating shaft, and the upper surface of the car bottom wheel seat is in contact with the car bottom plate.

[0015] Furthermore, the car floor assembly also includes side plates, and the ends of the car floor wheel seats are connected to the pillars via the side plates.

[0016] Furthermore, the car's bottom wheel seat is made of channel steel.

[0017] Furthermore, the upper surface of the car bottom wheel seat is connected to the car bottom plate by welding. This not only strengthens the car, but also reduces the space occupied by the car frame in the hoistway because the car bottom wheel seat is directly connected to the car bottom plate and the car bottom wheel is connected to the car bottom wheel seat.

[0018] Furthermore, the reinforcing ribs are connected to the lower surface of the car floor plate by welding. This is used to reinforce the car.

[0019] Furthermore, a buffer plate is installed on the lower surface of the wheel assembly, and a rubber pad is installed on the buffer plate. When the elevator suddenly falls, the rubber pad can act with the buffer at the bottom of the shaft to ensure the safety of the car.

[0020] The steel belt passes through the side panel opening and contacts the bottom wheel. The steel belt supports the entire car system, and the movement of the steel belt drives the bottom wheel to rotate, thereby realizing the raising or lowering of the entire car system.

[0021] Traditional elevators have shock-absorbing blocks at the bottom of the car, below which is a car support. The car support contains car bottom wheels, and the elevator's steel cables pass through the car support. When the elevator drive unit moves the steel cables, the shock-absorbing blocks reduce the vibration impact on the car. This invention uses a steel belt instead of the traditional elevator's steel cables. The steel belt itself has a shock-absorbing effect, so this invention eliminates the shock-absorbing blocks in the traditional design. The car bottom wheel seat is welded to the car bottom plate, which not only strengthens the car but also reduces the space occupied by the car frame in the hoistway. The top beam is connected to the car top plate by welding, further reducing the space occupied by the car frame in the hoistway. Attached Figure Description

[0053] Example 3:

[0054] Figure 1 The second embodiment of the car system of a steel belt elevator of the present invention is shown, including a car 1 and a car frame 2, wherein the car frame 2 is disposed outside the car 1 and connected to the car.

[0055] The car 1 includes a car top plate 11, a car bottom plate 12 and a side wall 13. The car top plate 11 and the car bottom plate 12 are connected by the side wall 13. The car top plate 11, the car bottom plate 12 and the side wall 13 form a cavity structure.

[0056] like Figure 1 and Figure 2 As shown, the car frame 2 includes a car top assembly 21, a car bottom assembly 22, and a column 23. The car top assembly 21 is connected to the upper surface of the car top plate 11, the car bottom assembly 22 is connected to the lower surface of the car bottom plate 12, and the side of the car bottom assembly 22 is connected to the side of the car top assembly 21 through the column 23.

[0057] The car roof assembly 21 is connected to the upper surface of the car roof panel 11 by welding, and the car floor assembly 22 is connected to the lower surface of the car floor panel 12 by welding.

[0058] Preferably, there are two columns 23, which are made of channel steel. The columns 23 are perpendicular to the horizontal plane.

[0059] like Figure 3 and Figure 7 As shown, the car roof assembly 21 includes a top beam 211, an upper boot assembly 212, a car roof side panel 213, and a car roof inspection box 214. The top beam 211 is connected to the upper surface of the car roof panel 11 by welding. The axis of the top beam 211 is perpendicular to the axis of the column 23. The top beam 211 is connected to the column 23 through the car roof side panel 213. The upper boot assembly 212 is connected to the upper end of the top beam 211. The car roof side panel 213 is connected to the edge of the car roof panel 11. The car roof inspection box 214 is connected to the upper end of the top beam 211.

[0060] The number of top beams 211 can be single or multiple. The top beams 211 are connected to the columns 23 and are used to stabilize the shape of the car 1 and reinforce the car 1. The top beams 211 are made of channel steel. The top beams 211 are in direct contact with the car top plate 11, reducing the space occupied by the car frame 2 in the hoistway.

[0061] The upper shoe assembly 212 is located at the end of the top beam 211. The upper shoe assembly 212 includes an upper guide shoe plate, an upper guide shoe, and a square oil cup. The guide shoe plate is connected to the upper end of the top beam 211, the upper guide shoe is connected to the upper surface of the guide shoe plate, and the square oil cup is connected above the upper guide shoe. The square oil cup is a lubrication device that not only improves the reliability of the elevator guide rail but also extends the service life of the guide rail. The elevator oil cup reduces friction between the guide shoe liner and the guide rail by lubricating the guide shoe, thereby improving the operational stability of the elevator.

[0062] The car roof side panel 213 is connected to the car roof panel 11 by welding. The car roof side panel 213 can reinforce the car 1. The top beam 211, the column 23 and the car roof side panel 213 are connected as one piece by bolts and other fasteners, which is more solid.

[0063] The car top inspection box 214 is located on the top of the car to facilitate safe, reliable, and convenient elevator maintenance by maintenance personnel.

[0064] The difference between this embodiment and the first and second embodiments is that:

[0065] like Figure 4 As shown, the car floor assembly 22 includes a reinforcing rib 221, a wheel seat assembly 222, and a car floor side panel 223. The car floor side panel 223 is connected to the edge of the car floor plate 12. The reinforcing rib 221 is attached to the lower surface of the car floor plate 11. The wheel seat assembly 222 is attached to the lower surface of the car floor plate 11. The end of the wheel seat assembly 222 is connected to the column 13.

[0066] The wheel assembly 222 includes a car bottom wheel 2221 and a car bottom wheel seat 2222. The car bottom wheel 2221 is connected to the car bottom wheel seat 2222 via a pivot. The car bottom wheel seat 2222 is made of steel beam and is welded to the car floor plate 12. This not only strengthens the car 11, but also reduces the space occupied by the car frame 2 in the hoistway because the car bottom wheel seat 2222 is in direct contact with the car floor plate 12.

[0067] like Figure 6 and Figure 8 As shown, the car bottom side panel 223 is connected to the column 13 through the side plate 224. The side plate 224 has an opening. The steel belt passes through the opening of the side plate 224 and contacts the car bottom wheel 2221. The movement of the steel belt drives the car bottom wheel 2221 to rotate.

[0068] The reinforcing rib 221 is a bent part that is connected to the car floor plate 12 by welding. Multiple reinforcing ribs 221 are arranged between the car floor wheel seats 2222 to reinforce the car 1.

[0069] like Figure 5 As shown, a buffer plate 225 is also provided on the lower surface of the wheel seat assembly 222. A rubber pad is provided on the buffer plate 225. When the elevator suddenly falls, the rubber pad can act with the buffer at the bottom of the shaft to ensure the safety of the car.

[0070] The working principle of the above embodiments is as follows:

[0071] The steel belt passes through the opening in the side plate 225 and contacts the bottom wheel 2221. The steel belt supports the entire car system. The elevator drive device drives the steel belt to move, thereby driving the bottom wheel 2221 to rotate, thus realizing the raising or lowering of the entire car system.

[0072] Traditional elevators have shock-absorbing blocks at the bottom of the car, with a car support below the blocks and a car wheel inside the support. The elevator's steel cable passes through the support. When the elevator drive unit drives the steel cable, the shock-absorbing blocks reduce the vibration impact on the car 1. In this invention, a steel belt replaces the steel cable of the traditional elevator. The steel belt itself has a shock-absorbing effect, so the shock-absorbing blocks in the traditional design are removed. The car wheel seat 2222 is welded to the car floor plate 12, which not only strengthens the car 1, but also reduces the space occupied by the car frame 2 in the shaft because the car wheel seat 2222 is directly connected to the car floor plate 12 and the car wheel 2221 is connected to the car wheel seat 2222. The top beam 211 is directly connected to the car top plate 11, which also reduces the space occupied by the car frame 2 in the shaft.

[0073] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention are included within the scope of protection of the present invention.
