Description

Technical Field

[0001] The utility model relates to an elevator installation structure, more specifically, to a household elevator load-bearing structure. Background Art

[0002] A home elevator is a type of elevator that is installed in a user's home. The top floor of a user's home is often used to store miscellaneous items, and the floor height is lower than that of a normal floor, so the requirements for elevator installation are higher; the existing load-bearing frame structure cannot meet the top floor height requirements of existing home elevators.

[0003] For example: Chinese patent announcement number CN218708421U, announcement date March 24, 2023, the name of the utility model is a high-stability integrated freight elevator load-bearing mechanism, the application provides an elevator load-bearing mechanism, including two main load-bearing beams and two head channel steels, the two head channel steels are fixedly connected to the lower end faces on the left and right sides of the two main load-bearing beams, and the main engine and car side common load-bearing beam is fixedly connected between the upper end faces of the two main load-bearing beams. The scheme connects the counterweight load area with the load area on the car side through the load area of the freight elevator main engine, so that the counterweight side and the car side share a set of support systems, and utilizes the lower load-bearing beam on the car side, the common load-bearing beam on the main engine and the car side, and the counterweight side load-bearing beam to connect the main load-bearing area, counterweight side load, main engine load, and car load in turn to form a whole, simplifying the structure as much as possible, making its force clear, and reducing the possibility of system instability due to the compact structure caused by the "one" type arrangement. However, this solution directly arranges larger structures such as the traction machine above the load-bearing beam, which increases the installation height of the top of the load-bearing beam and cannot meet the requirements of the small installation space at the top of the home elevator. Utility Model Content

[0004] The utility model overcomes the problem that the existing load-bearing frame structure cannot meet the top-floor height requirement of the existing home elevator, and provides a home elevator load-bearing structure. This solution can ensure the safe operation distance of the elevator, reduce the height of the main machine position, ensure the safe space of the car gantry position, and the car can be made higher.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a load-bearing structure for a household elevator, comprising a first load-bearing beam and a second load-bearing beam, wherein the position of the first load-bearing beam is higher than that of the second load-bearing beam, a traction machine assembly is provided on the second load-bearing beam, a traction sheave assembly is provided on the first load-bearing beam, and the top position of the traction machine assembly is lower than the top position of the traction sheave assembly. In this solution, the first load-bearing beam is the car-side load-bearing beam, and the second load-bearing beam is the counterweight-side load-bearing beam. The overall size of the traction machine assembly is relatively large, so the traction machine assembly is installed on the second load-bearing beam at a lower position, and the overall size of the traction sheave assembly is relatively small, so the traction sheave assembly is installed on the first load-bearing beam at a higher position. In this way, the installation space of the load-bearing structure and the drive device at the top of the elevator can be greatly reduced, thereby ensuring the safe space of the car gantry position and allowing the car to be made higher.

[0006] Preferably, the first load-bearing beam includes a first mounting seat and a first support beam arranged parallel to the first mounting seat, with a space provided between the first support beams. The first mounting seat serves as a mounting and fixing component for the first load-bearing beam, and the first support beam serves as a bearing component for the first load-bearing beam. The provision of two first support beams can improve the stability of the traction sheave assembly installation. Furthermore, the space reserved between the first support beams can be used to pass a wire rope for connecting to the car.

[0007] Preferably, the second load-bearing beam includes a second mounting base and a second support beam arranged parallel to the second mounting base; a space is provided between the second support beams. The second mounting base serves as a mounting and fixing component for the second load-bearing beam, and the second support beam serves as a bearing component for the second support beam. The provision of two second support beams improves the stability of the traction machine assembly installation. The space between the second support beams is used to pass a wire rope through for connection to the traction sheave.

[0008] Preferably, the traction machine assembly includes a traction machine and a traction machine mounting seat, wherein the traction machine mounting seat is arranged on the second support beam. The traction machine mounting seat is used to mount the traction machine and is arranged on the two second support beams.

[0009] Preferably, the traction sheave assembly comprises a traction sheave and a traction sheave mounting seat, wherein the traction sheave mounting seat is arranged on the first support beam. The traction sheave mounting seat is used to mount the traction sheave and is arranged on the two first support beams.

[0010] Preferably, the height difference between the first load-bearing beam and the second load-bearing beam is 400±10 mm. The height difference between the first load-bearing beam and the second load-bearing beam is arranged to be around 400 mm to meet the installation space of the traction machine assembly.

[0011] Preferably, an intermediate wheel is disposed on the second load-bearing beam and between the traction sheave assembly and the traction machine assembly. The intermediate wheel is located in the same vertical plane as the traction sheave assembly and the traction machine assembly and is positioned lower than the traction sheave assembly and the traction machine assembly. The intermediate wheel is used to transmit the wire rope between the traction sheave and the traction machine, facilitating the winding and motion transmission of the wire rope. Therefore, the intermediate wheel needs to be disposed midway between the traction sheave and the traction machine and in the same plane.

[0012] Preferably, a rope end assembly is provided on the first and second load-bearing beams, and is positioned near the traction machine assembly and the traction sheave assembly. The rope end assembly can be used to secure the wire rope and adjust its tension. The connection device connects the wire rope to the elevator car and the traction machine, ensuring smooth and safe elevator movement.

[0013] Preferably, the rope end assembly includes a rope end mounting plate and a fixing bolt. The fixing bolt extends through the mounting plate and is sheathed with a spring. A rope loop is secured to the bottom of the fixing bolt. The rope end mounting plate secures the rope end assembly, the fixing bolt is sheathed with the spring and connects the wire rope. The spring's elastic force adjusts the tension difference between the suspended wire ropes and reduces vibration in the elevator system. The rope loop secures and connects the wire rope.

[0020] The technical solution of the present invention will be further described below with reference to specific embodiments and in conjunction with the accompanying drawings.

[0021] Example 1: Figures 1 to 4 A household elevator load-bearing structure shown in the figure includes a first load-bearing beam 1 and a second load-bearing beam 2, and the first load-bearing beam 1 and the second load-bearing beam 2 are arranged in the elevator shaft, wherein the first load-bearing beam 1 is arranged at a higher height than the second load-bearing beam 2, and the traction machine assembly 3 is arranged on the second load-bearing beam 2, and the traction wheel assembly 4 is arranged on the first load-bearing beam 1. Since the overall size of the traction machine assembly 3 is larger, the position height of the second load-bearing beam 2 is lower, so that the low-positioned second load-bearing beam 2 can reduce the overall height of the traction machine assembly 3, and the traction machine assembly 3 does not directly pull the car, so it does not reduce the running stroke of the car and affect the size of the car; the overall size of the traction wheel assembly 4 is much smaller than that of the traction machine assembly 3, so that the traction wheel assembly 4 can be arranged on the relatively high first load-bearing beam 1, and a transmission structure is formed between the traction machine 3.1 and the traction wheel 4.1 between the first load-bearing beam 1 and the second load-bearing beam 2 for lifting the car. This solution greatly reduces the installation space of the load-bearing structure and drive device on the top of the elevator, ensuring a safe space for the car gantry position. The car can be made higher, which can meet the environment where the installation space on the top of the home elevator is small.

[0022] The first load-bearing beam 1 includes two first mounting seats 5 and two first support beams 6. The first mounting seat 5 is a T-shaped plate structure. The first mounting seat 5 includes a vertical plate and a horizontal plate. The vertical plate can be used to be installed in the elevator shaft. A plurality of mounting hole structures are provided on the vertical plate for installation in the elevator shaft, while the horizontal plate is used to install the first support beam 6. Two pairs of mounting holes are also arranged on the horizontal plate for installation and connection with the first support beam 6. The first support beam 6 is a C-shaped channel steel. There are also two first support beams 6. The two C-shaped first support beams 6 are arranged back to back. Mounting holes are arranged at both ends of the first support beam 6 so that they can be bolted to the mounting holes on the first mounting seat 5. The two first mounting seats 5 are respectively arranged at the two ends of the two parallel first support beams 6.

[0023] The second load-bearing beam 2 includes two second mounting blocks 7 and two second support beams 8. The second mounting blocks 7 are T-shaped plate structures and include a vertical plate and a horizontal plate. The vertical plate can be installed in the elevator shaft and is provided with multiple mounting holes for installation in the elevator shaft, while the horizontal plate is used to mount the second support beams 8. The horizontal plate is also provided with two pairs of mounting holes for mounting and connecting to the second support beams 8. The second support beams 8 are C-shaped channel steels. There are also two second support beams 8. The two C-shaped second support beams 8 are arranged back to back, with mounting holes at both ends of the second support beams 8, allowing them to be bolted to the mounting holes on the second mounting blocks 7. The two second mounting blocks 7 are respectively arranged at the two ends of the two parallel second support beams 8.

[0024] It should be noted that a certain gap is set between the two first support beams 6 and between the two second support beams 8, and the gap size is 50 mm; the gap between the first support beams 6 is used to pass the wire rope for lifting the car, and the wire rope is passed through the traction sheave assembly 4 and then passes through the gap between the first support beams 6 to connect to the car; the gap between the second support beams 8 is used to pass the wire rope connected to the traction sheave 4.1 on the traction machine 3.1; at the same time, the gap between the first support beam 6 and the second support beam 8 can also increase the installation plane of the support beam to a certain extent, thereby improving the installation stability of the traction sheave assembly 4 and the traction machine assembly 3.

[0025] The traction sheave assembly 4 comprises a traction sheave mounting base 4.2 and a traction sheave 4.1. The traction sheave mounting base 4.2 consists of two parallel C-shaped channel steels, arranged back-to-back. The C-shaped channel steels are fixedly connected to the first support beam 6 using fasteners such as bolts or screws. Two shaft holes are provided on the opposing surfaces of the two C-shaped steels for mounting the shafts at either end of the traction sheave 4.1. Once mounted on the traction sheave mounting base 4.2, the traction sheave 4.1 maintains a certain distance from the first support beam 6 to prevent interference. The traction sheave 4.1 transmits the motion of the wire rope and is located at the elevator car's hoisting position.

[0026] The hoist assembly 3 includes a hoist mounting base 3.2 and a hoist 3.1. The hoist mounting base 3.2 also consists of two parallel C-shaped channel steels, arranged back-to-back. The C-shaped channel steels are positioned above the second support beam 8 and are fixed to the second support beam 8 via fasteners such as bolts or screws. The hoist 3.1 is supported on the upper surfaces of the two C-shaped channel steels.

[0027] After the traction sheave assembly 4 and the traction machine assembly 3 are installed and arranged, the top height position of the traction machine assembly 3 should be lower than the top height position of the traction sheave assembly 4, so that the height of the load-bearing structure is determined by the top position of the traction sheave assembly 4. It should be noted that, in this embodiment, the height difference between the first load-bearing beam 1 and the second weighing beam 2 is 400 mm to meet the installation space of the traction machine assembly 4.

[0028] An intermediate pulley 9 is located between the traction sheave assembly 4 and the hoisting machine assembly 3. This intermediate pulley 9 is mounted on the second load-bearing beam 2 and at its base. This intermediate pulley 9 is used to transfer the wire rope between the hoisting machine assembly 3 and the traction sheave assembly 4. Specifically, the wire rope exits the hoisting machine 3.1 and is wound around the base of the intermediate pulley 9. From there, the wire rope is wound upwards around the top of the traction sheave 4.1, and then downwards to the car. The traction sheave 4.1, hoisting machine 3.1, and intermediate pulley 9 are all located on the same vertical plane, preventing wear on the wire rope and other components.

[0029] Example 2: Figures 1 to 4 A household elevator load-bearing structure shown in the figure includes a first load-bearing beam 1 and a second load-bearing beam 2, and the first load-bearing beam 1 and the second load-bearing beam 2 are arranged in the elevator shaft, wherein the first load-bearing beam 1 is arranged at a higher height than the second load-bearing beam 2, and the traction machine assembly 3 is arranged on the second load-bearing beam 2, and the traction wheel assembly 4 is arranged on the first load-bearing beam 1. Since the overall size of the traction machine assembly 3 is larger, the position height of the second load-bearing beam 2 is lower, so that the low-positioned second load-bearing beam 2 can reduce the overall height of the traction machine assembly 3, and the traction machine assembly 3 does not directly pull the car, so it does not reduce the running stroke of the car and affect the size of the car; the overall size of the traction wheel assembly 4 is much smaller than that of the traction machine assembly 3, so that the traction wheel assembly 4 can be arranged on the relatively high first load-bearing beam 1, and a transmission structure is formed between the traction machine 3.1 and the traction wheel 4.1 between the first load-bearing beam 1 and the second load-bearing beam 2 for lifting the car. This solution greatly reduces the installation space of the load-bearing structure and drive device on the top of the elevator, ensuring a safe space for the car gantry position. The car can be made higher, which can meet the environment where the installation space on the top of the home elevator is small.

[0030] The first load-bearing beam 1 includes two first mounting seats 5 and two first support beams 6. The first mounting seat 5 is a T-shaped plate structure. The first mounting seat 5 includes a vertical plate and a horizontal plate. The vertical plate can be used to be installed in the elevator shaft. A plurality of mounting hole structures are provided on the vertical plate for installation in the elevator shaft, while the horizontal plate is used to install the first support beam 6. Two pairs of mounting holes are also arranged on the horizontal plate for installation and connection with the first support beam 6. The first support beam 6 is a C-shaped channel steel. There are also two first support beams 6. The two C-shaped first support beams 6 are arranged back to back. Mounting holes are arranged at both ends of the first support beam 6 so that they can be bolted to the mounting holes on the first mounting seat 5. The two first mounting seats 5 are respectively arranged at the two ends of the two parallel first support beams 6.

[0031] The second load-bearing beam 2 includes two second mounting blocks 7 and two second support beams 8. The second mounting blocks 7 are T-shaped plate structures and include a vertical plate and a horizontal plate. The vertical plate can be installed in the elevator shaft and is provided with multiple mounting holes for installation in the elevator shaft, while the horizontal plate is used to mount the second support beams 8. The horizontal plate is also provided with two pairs of mounting holes for mounting and connecting to the second support beams 8. The second support beams 8 are C-shaped channel steels. There are also two second support beams 8. The two C-shaped second support beams 8 are arranged back to back, with mounting holes at both ends of the second support beams 8, allowing them to be bolted to the mounting holes on the second mounting blocks 7. The two second mounting blocks 7 are respectively arranged at the two ends of the two parallel second support beams 8.

[0032] It should be noted that a certain gap is set between the two first support beams 6 and between the two second support beams 8, and the gap size is 50 mm; the gap between the first support beams 6 is used to pass the wire rope for lifting the car, and the wire rope is passed through the traction sheave assembly 4 and then passes through the gap between the first support beams 6 to connect to the car; the gap between the second support beams 8 is used to pass the wire rope connected to the traction sheave 4.1 on the traction machine 3.1; at the same time, the gap between the first support beam 6 and the second support beam 8 can also increase the installation plane of the support beam to a certain extent, thereby improving the installation stability of the traction sheave assembly 4 and the traction machine assembly 3.

[0033] The traction sheave assembly 4 comprises a traction sheave mounting base 4.2 and a traction sheave 4.1. The traction sheave mounting base 4.2 consists of two parallel C-shaped channel steels, arranged back-to-back. The C-shaped channels are fixed to the first support beam 6 using fasteners such as bolts or screws. Two shaft holes are provided on the opposing surfaces of the two C-shaped channels for mounting the shafts at either end of the traction sheave 4.1. Once mounted on the traction sheave mounting base 4.2, the traction sheave 4.1 maintains a certain distance from the first support beam 6 to prevent interference. The traction sheave 4.1 transmits the motion of the wire rope and is located at the elevator car's hoisting position.

[0034] The hoist assembly 3 includes a hoist mounting base 3.2 and a hoist 3.1. The hoist mounting base 3.2 also consists of two parallel C-shaped channel steels, arranged back-to-back. The C-shaped channel steels are positioned above the second support beam 8 and are fixed to the second support beam 8 via fasteners such as bolts or screws. The hoist 3.1 is supported on the upper surfaces of the two C-shaped channel steels.

[0035] After the traction sheave assembly 4 and the traction machine assembly 3 are installed and arranged, the top height position of the traction machine assembly 3 should be lower than the top height position of the traction sheave assembly 4, so that the height of the load-bearing structure is determined by the top position of the traction sheave assembly 4. It should be noted that, in this embodiment, the height difference between the first load-bearing beam 1 and the second weighing beam 2 is 400 mm to meet the installation space of the traction machine assembly 4.

[0036] An intermediate pulley 9 is located between the traction sheave assembly 4 and the hoisting machine assembly 3. This intermediate pulley 9 is mounted on the second load-bearing beam 2 and at its base. This intermediate pulley 9 is used to transfer the wire rope between the hoisting machine assembly 3 and the traction sheave assembly 4. Specifically, the wire rope exits the hoisting machine 3.1 and is wound around the base of the intermediate pulley 9. From there, the wire rope is wound upwards around the top of the traction sheave 4.1, and then downwards from the top of the traction sheave 4.1 to connect to the car. The traction sheave 4.1, hoisting machine 3.1, and intermediate pulley 9 are all located on the same vertical plane, preventing wear on the wire rope and other components.

The rope end assembly 10 includes a rope end mounting plate 10.1, a fixing bolt 10.2, a spring 10.3, a nut, and a rope loop 10.4. The rope end mounting plate 10.1 is the mounting base of the rope end assembly and is installed in the gap between the first support beam 6 and the second support beam 8. The fixing bolt 10.2 passes through the rope end mounting plate 10.1. The fixing bolt 10.2 is located on the upper side of the rope end mounting plate 10.1 and is sleeved with a spring 10.3. The spring 10.3 is limited in position by a limit plate and a nut, so that the spring 10.3 is in a certain compressed state. The fixing bolt 10.2 is located on the lower side of the rope end mounting plate 10.1 and is fixed with a rope loop 10.4. The rope loop is used to fix and connect the end of the wire rope. There are three sets of rope end assemblies 10, which can be used to fix the wire rope and adjust the wire rope tension. The wire rope is connected to the elevator car and the traction machine 3.1 through the connecting device to ensure that the elevator can rise and fall smoothly and safely and reduce the vibration of the elevator system.
