[0041] As shown in Figure 1 and Figure 2 The elevator equipment hoisting method provided by the embodiments of the present application comprises the following steps:

[0042] At least two hoisting equipment 001 are arranged at the top of the elevator shaft;

[0043] A plurality of equipment frames 002 are stacked from bottom to top, so that the plurality of equipment frames 002 are placed inside the elevator shaft and located below the hoisting equipment 001;

[0044] The elevator components are respectively mounted in the plurality of equipment frames 002;

[0045] The plurality of equipment frames 002 are hoisted by at least two hoisting devices 001, and the hoisted equipment frames 002 are fixed in the elevator shaft.

[0046] The elevator equipment hoisting method can realize the modularization of elevator components, and the elevator components can be divided and loaded on the plurality of equipment frames 002, so that the shaft side bearing capacity during hoisting can be reduced, and the building strength requirement of the elevator shaft is reduced, which is beneficial to reducing the building cost of the elevator shaft. In addition, the elevator equipment hoisting can distribute the hoisting weight according to the building bearing capacity, and can be hoisted in modules without the need for overweight hoisting, so that hoisting review is no longer needed, and the construction progress of the elevator can be accelerated.

[0047] In the embodiment of the present application, the step of stacking the plurality of equipment frames 002 from bottom to top and placing the plurality of equipment frames 002 inside the elevator shaft includes: installing one equipment frame 002 at a first installation position inside the elevator shaft, as shown in Figure 1 and Figure 2 The equipment frame 002 is placed on the bottom support 003, and the bottom support 003 is fixed to the side wall of the elevator shaft, the equipment frame 002 is supported by the bottom support 003, and is kept at the first installation position. Then, the remaining equipment frames 002 are stacked on the equipment frame 002 installed at the first installation position, and the number of stacked equipment frames 002 is greater than 2. The elevator components are respectively installed in the plurality of equipment frames 002, and can be hoisted separately during hoisting, which realizes the modularization of the equipment and reduces the requirement of the building strength of the elevator shaft during hoisting of the elevator.

[0048] As shown in Figure 3 , Figure 4 and Figure 5 The step of hoisting the plurality of equipment frames 002 by at least two hoisting devices 001 and fixing the hoisted equipment frames 002 in the elevator shaft includes:

[0049] The top equipment frame 002 is hoisted and fixed in the elevator shaft by using at least two hoisting devices 001 to connect the top equipment frame 002;

[0050] The remaining equipment frames 002 are hoisted and fixed layer by layer in the order from top to bottom, and the lowest equipment frame 002 is fixed at a second installation position;

[0051] The equipment frames 002 above the second installation position are released layer by layer from bottom to top, so that the plurality of equipment frames 002 are stacked from bottom to top.

[0052] Specifically, the lifting process adopts the lifting method, the center of gravity of the hoisted equipment frame 002 and the elevator components is located inside the figure formed by the connecting line of the lifting points, the top of the lifting equipment 001 is connected to the top lifting point 101, the lower end of the lifting equipment 001 is connected to the equipment lifting point 102, the equipment frame 002 is hoisted by at least two lifting equipment 001, the connecting line of the plurality of lifting equipment 001 from the top lifting point 101 to the equipment lifting point 102 is symmetrical relative to the longitudinal center line of the elevator shaft, so as to avoid the deflection of the equipment frame 002 in the elevator shaft. In addition, after the equipment frame 002 is hoisted layer by layer from top to bottom by the lifting equipment 001, the lowermost equipment frame 002 is first fixed to the second installation position, and then the equipment frame 002 above is released in turn from bottom to top, so that the plurality of equipment frames 002 can be stacked.

[0053] In an optional embodiment, the step of hoisting the plurality of equipment frames 002 by at least two lifting equipment 001 and fixing the hoisted equipment frames 002 in the elevator shaft comprises:

[0054] The equipment frame 002 below the top layer or the top layer is connected by at least two lifting equipment 001, hoisted and fixed in the elevator shaft;

[0055] The plurality of equipment frames 002 are divided into at least one group from top to bottom, and are hoisted and fixed in the elevator shaft respectively until the lowermost equipment frame 002 is hoisted and fixed to the second installation position.

[0056] Under the condition that the lifting load is allowed, a plurality of equipment frames 002 can be lifted at a time, and at least two lifting equipment 001 can be connected to the bottom layer of the equipment frame 002, so as to reduce the number of hoisting operations. When a plurality of equipment frames 002 are lifted at a time, the lifting equipment 001 is connected to the bottom layer of the group of equipment frames 002, so that the hoisting of the group of equipment frames 002 can be realized quickly. In the lifting process, the bottom layer of each group of equipment frames 002 is connected to the elevator shaft, and after the bottom layer of the lowermost group of equipment frames 002 is fixed, each group of equipment frames 002 is released in turn from bottom to top, so that the hoisted plurality of equipment frames 002 can be stacked again.

[0057] As shown in Figure 1 , Figure 3 and Figure 4 , the step of fixing the hoisted equipment frame 002 in the elevator shaft comprises: providing a supporting device 004 on the equipment frame 002, clamping the elevator shaft guide rail by the supporting device 004, and locking the equipment frame 002 in the corresponding installation position inside the elevator shaft.

[0058] In addition, the equipment frame 002 can be connected to the hoistway ring beam, and when connected, the lifting point on the equipment frame 002 can be connected to the hoistway ring beam through a lifting belt, so as to fix the equipment frame 002 in the absence of the default support device 004.

[0059] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the elevator equipment provided by the embodiment of the present application comprises: at least two lifting devices 001 installed on the top of the elevator hoistway; a plurality of equipment frames 002 stacked from bottom to top inside the elevator hoistway, the lowermost equipment frame 002 being connected to the elevator hoistway; and elevator components installed inside the equipment frame 002.

[0060] In the above-mentioned elevator equipment, the elevator components are respectively loaded by the plurality of equipment frames 002, and according to the building load capacity of the elevator hoistway, the plurality of equipment frames 002 can be lifted one by one or in groups, which can alleviate the technical problem that the overall weight of the elevator equipment is too large, resulting in too high a requirement for the building strength of the elevator hoistway, which is not only beneficial to reduce the construction cost of the elevator hoistway, but also avoids the delay of the construction period due to the review of the overloading lifting.

[0061] In the embodiment of the present application, the equipment frame 002 is provided with a support device 004 clamping the elevator hoistway guide rail, or the lifting point on the equipment frame 002 is connected to the hoistway ring beam. The plurality of support devices 004 can be respectively fixed relative to the elevator hoistway, so as to reduce the load bearing of the bottom equipment frame 002, and further reduce the gravity borne by the bottom support 003.

[0062] In addition, the equipment frame 002 has a gap space with the side wall of the elevator hoistway, and the lifting device 001 can pass through the gap space to be connected to any equipment frame 002 below the next top layer, so that the number of single lifting equipment frames 002 can be reasonably arranged according to the building strength of the elevator hoistway and the load capacity of the lifting device 001, without requiring too high a requirement for the building strength of the elevator hoistway, thereby reducing the construction cost of the hoistway.

[0063] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that: the technical solutions recorded in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
