Description

Technical field:

[0001] The utility model relates to a novel rope speed limiter mounting seat for a machine room-less home elevator, in particular to a mounting seat structure which combines a rope head, a speed limiter and a weighing device of the machine room-less home elevator, and belongs to the technical field of elevator equipment. Background technology:

[0002] An elevator rope end, the connection between the elevator wire rope and the elevator car, counterweight, or other fixed structure, is a crucial component of safe elevator operation. An overspeed governor is a safety device that ensures the elevator can be quickly stopped in the event of overspeed or suspension failure, ensuring passenger safety.

[0003] The traditional elevator's machine room-less car side rope head combination fixing method is to fix the fixing base to the back of the guide rail, and then install the speed limiter and car rope head combination above the fixing base. Since the two sides of the guide rail are arranged separately and the force on the speed limiter and rope head combination is uneven, this will generate a large shear force on the guide rail, and the uneven force can easily cause local bending and deformation of the guide rail, which has a great impact on the overall force of the guide rail. Since the speed limiter is also installed in accordance with this installation method, it also needs to occupy space in the depth direction of the well, which will result in a small available space in the depth direction of the well. At the same time, since the speed limiter is also installed on the back of the guide rail through the mounting base, it will cause inconsistent lateral tension in the front and rear directions of the guide rail, which will aggravate the unbalanced force on the guide rail. Summary of the invention:

[0004] In view of the above shortcomings, the present invention provides a novel rope speed governor mounting seat for a machine room-less home elevator. The present invention is achieved through the following technical solutions:

[0005] A new type of rope speed limiter mounting seat for a machine room-less home elevator includes a rear mounting plate, a bottom sealing plate, a left reinforcing plate, a right reinforcing plate, a weighing sensor electrical component, an upper pressure plate, a rope head assembly, and a speed limiter. The invention is characterized in that the rear mounting plate, the bottom sealing plate, and the left and right reinforcing plates are welded as a whole; the rear mounting plate is fixed to the shaft wall by expansion bolts; the bottom sealing plate is installed above the guide rail and contacts the top of the guide rail, and can be reinforced by spot welding for secondary protection; the weighing sensor electrical component is fixed between the upper pressure plate and the bottom sealing plate; the rope head assembly passes through the mounting holes of the upper pressure plate and the bottom sealing plate, and two are symmetrically arranged on the left and right sides; the speed limiter is fixed to the upper pressure plate by bolts.

[0006] Furthermore, the bottom sealing plate is provided with mounting holes for installing the rope head assembly, the speed limiter, the weighing sensor electrical components, and the rear side mounting plate is processed with a connection hole for connecting to the well wall.

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] 1) The utility model can effectively improve the utilization rate of the shaft space, optimize the force condition of the guide rail, and improve the stability of the guide rail.

[0009] 2) After the speed governor and rope head assembly of the present invention is installed, the structure is compact, and compared with the traditional installation method, the hoistway space occupancy rate is reduced by 50%, while facilitating the arrangement and installation of other components.

[0010] 3) The utility model can be installed with a car weighing device, which is simpler to install and more convenient to maintain than a traditional car weighing device. It also saves space for car bottom installation and allows for more flexible arrangement of the elevator pit and car bottom structure. Description of the drawings:

[0015] like Figure 1As shown, a new type of rope speed limiter mounting seat for a machine room-less home elevator includes a rear mounting plate 1, a bottom sealing plate 8, a left reinforcing plate 6, a right reinforcing plate 3, a weighing sensor electrical component 2, an upper pressure plate 7, a rope head assembly 4, and a speed limiter 5. The rear mounting plate 1, the bottom sealing plate 8, the left reinforcing plate 6, and the right reinforcing plate 3 are welded as a whole, and the left reinforcing plate 6 and the right reinforcing plate 3 are welded to both ends of the rear mounting plate 1 to strengthen the structural strength. The rear mounting plate 1 is fixed to the shaft wall by expansion bolts, thereby fixing the entire rope speed limiter mounting seat to the shaft wall. The bottom sealing plate 8 is installed above the guide rail and contacts the top of the guide rail. Secondary protection can be provided by spot welding reinforcement, which can optimize the stress condition of the guide rail and improve the stability of the guide rail. The weighing sensor electrical component 2 is fixed between the upper pressure plate 7 and the bottom sealing plate 8, and is fixed to the bottom sealing plate 8 by bolts. The upper pressure plate 7 and the bottom sealing plate 8 compress the weighing sensor electrical component 2, thereby playing a role in weighing. It is simpler to install than the traditional car weighing device, saves space for car bottom installation, and flexibly arranges the elevator pit and car bottom structure. The rope end assembly 4 passes through the installation holes of the upper pressure plate 7 and the bottom sealing plate 8, and two are symmetrically arranged on both sides of the mounting seat, making the rope end arrangement more compact. Compared with the traditional installation method, it reduces the space occupancy rate of the shaft and facilitates the arrangement and installation of other components. The speed limiter 5 is fixed to the upper pressure plate 7 by bolts.

[0016] like Figure 2-3 As shown, the bottom sealing plate 8 is provided with mounting holes for installing the rope end assembly 4, the speed limiter 5, and the weighing sensor electrical component 2, and the rear mounting plate 1 is processed with a connection hole for connecting to the well wall.
