Technical Field

[0001] This utility model relates to a new type of elevator shaft frame specifically for old residential communities and its combined installation equipment. Background Technology

[0002] my country is vigorously promoting the installation of elevators in old residential buildings with stairs. Traditional elevator shafts use rectangular tubes as materials, which are cut and welded on the construction site. This installation method requires the use of large lifting equipment and the construction of steel frames. All shaft assembly and installation must be carried out at high altitudes, which poses great construction safety hazards and has too high management costs.

[0003] Another type of elevator shaft frame uses H-beams or angle steel for bolt assembly. The combination of these two types of steel has a poor appearance, and this type of elevator shaft frame has very poor stability during elevator operation. Utility Model Content

[0012] The rectangular tube columns and crossbeams of the derrick are fixedly connected to the column holes B by bolts passing through the winch holes to form an elevator derrick.

[0013] The elevator shaft is also equipped with exterior decorative panels.

[0014] A new type of lifting equipment for elevator shafts in old residential communities consists of an external fixing frame and an internal fixing frame in the elevator shaft.

[0015] The external fixed frame of the elevator shaft includes a combined hydraulic cylinder square column, crossbeam, flange, hydraulic cylinder piston rod and linear guide rail;

[0016] The combined hydraulic cylinder consists of four square columns, which are fixedly connected by multiple crossbeams.

[0017] The bottom of each of the four combined hydraulic cylinder square columns is equipped with a flange.

[0050] The elevator shaft 3 is also equipped with an exterior decorative panel.

[0051] A new type of lifting device for elevator shaft frame 3 in old residential communities, consisting of an external fixed frame 1 and an internal fixed frame 2 in the elevator shaft;

[0052] The elevator shaft external fixed frame 1 includes a combined hydraulic cylinder square column 1.1, a crossbeam 1.2, a flange 1.3, a hydraulic cylinder piston rod 1.4, and a linear guide rail 1.5;

[0053] The combined hydraulic cylinder square column 1.1 consists of four columns, which are fixedly connected by multiple crossbeams 1.2;

[0054] The bottom of each of the four combined hydraulic cylinder square columns 1.1 is equipped with a flange 1.3;

[0055] Each of the four combined hydraulic cylinder square columns 1.1 is equipped with a hydraulic cylinder piston rod 1.4, and this combination constitutes the existing hydraulic cylinder.

[0056] The four combined hydraulic cylinder square columns 1.1 are each equipped with linear guide rails 1.5;

[0057] The elevator shaft internal fixing frame 2 includes a rectangular tube column 2.1, a horizontal tube A 2.2, a fixing frame connector 2.3, a rolling guide rail 2.4, a lifting beam 2.5, a slider 2.6, and a horizontal tube B 2.7;

[0058] There are four rectangular tube columns 2.1, which are fixedly connected by multiple horizontal tubes A2.2;

[0059] A fixing bracket connector 2.3 is provided at the top of each rectangular tube column 2.1;

[0060] Multiple sets of rolling guide rails 2.4 are provided on the two inner sides of each rectangular tube column 2.1;

[0061] The two rolling guides 2.4 are arranged at right angles between them;

[0062] A slider 2.6 is fixedly connected to one side below each rectangular tube column 2.1;

[0063] There are two horizontal tubes B2.7, and both ends of the horizontal tubes B2.7 are fixedly connected to the bottom of the rolling guide rail 2.4;

[0064] The lifting beam 2.5 consists of two beams, each positioned above one of the two horizontal pipes B2.7;

[0065] The slider 2.6 is mounted on the linear guide rail 1.5;

[0066] The fixed bracket connector 2.3 is fixedly connected to the cylinder piston rod 1.4 by screws.

[0067] The installation process for modular installation equipment includes the following steps:

[0068] Step 1: After connecting the top layer of elevator shaft 3 with bolts, fix it to the base plate located on the foundation of the elevator shaft. Since the elevator shaft is bolted, the elevator shaft can be quickly positioned on the foundation.

[0069] Step 2: Fix the elevator shaft fixing frame 2 to the elevator shaft frame 3 according to the fixed position of the elevator shaft frame 3, and use the rolling guide rail 2.4 to tightly attach to the rectangular tube column 3.1 and connect to the horizontal tube A2.2;

[0070] Step 3: Based on the position of the inner fixed bracket 2 in the elevator shaft, continue to install the outer fixed bracket 1 in the elevator shaft. Connect it with the slider 1.6 on the linear guide rail 1.5 and the rectangular tube column 2.1. At the same time, fix the cylinder piston rod 1.4 to the fixed bracket connector 2.3 with screws.

[0071] Installation process of elevator shaft 3

[0072] After the modular installation equipment is installed, place the elevator shaft frame 3 in the designated position on the lifting beam 2.5, and start the equipment power. At this time, the piston rods 1.4 of the four modular hydraulic cylinder columns 1.1 will start simultaneously, which will lift the fixed frame 2 inside the elevator shaft. The lifting beam 2.5 of the fixed frame 2 inside the elevator shaft will also lift the elevator shaft frame 3. When the required height is reached, stop lifting, and connect the assembly of the elevator shaft frame 3 on the next floor to the top elevator shaft frame 3. After the connection is completed, remove the lifting beam 2.5. After the lifting beam 2.5 is removed, start the modular installation equipment to move in the reverse direction back to the starting point. After several rounds of installation, the elevator shaft frame 3 can be welded and fixed to the base plate.

[0073] Innovations in the combined installation of elevator shaft 3 and elevator shaft lifting equipment

[0074] 1. Since the elevator shaft frame 3 is made of rectangular tube, the rolling guide rail 2.4 of the lifting equipment can form a right-angle sliding on the right-angle surface of the elevator shaft frame 3. By utilizing the right-angle shape of the rectangular tube, the innovative vertical sliding of the fixed frame 2 and the elevator shaft frame 3 in the elevator shaft is realized.

[0075] 2. The elevator shaft 3 is moved through a composite motion using two sets of guide wires. This method effectively ensures the integrity of the elevator shaft 3 during the lifting process and the verticality of the shaft installation. When the elevator shaft 3 is installed by the elevator shaft lifting equipment, the elevator shaft 3 can operate safely through the linear guide rail 1.5 and the slider 2.6, which are fastened to the rolling guide rail 2.4. After the elevator shaft 3 is initially installed and the lifting beam 2.5 is removed, the fixed frame 2 inside the elevator shaft moves downward, and the fixed frame 2 inside the elevator shaft will automatically correct the elevator shaft 3.

[0076] 3. The combination of elevator shaft lifting equipment and modular bolt fixing connection method realizes the standardized and factory-based operation of elevator shaft 3. The installation of elevator shaft is transformed from a complex on-site production process to a standardized installation process. The installation methods of steel frame, decorative materials, elevator host, large lifting equipment and external scaffolding of elevator shaft 3 are replaced by the new modular installation.

[0077] The installation principle of this utility model is to install it in a top-down sequence, that is, to first assemble and install the top of the elevator shaft frame 3, and to do so at the same time as the external decoration. Therefore, no one needs to do high-altitude work, and the elevator shaft frame 3 is installed and assembled into a shaft in one go.
