Description

Technical Field

[0001] The utility model relates to the field of installing elevators, and particularly relates to a pre-installed counterweight frame structure for a steel-frame elevator. Background Art

[0002] The renovation of adding elevators to old residential areas is being increasingly promoted. Due to the narrow construction environment in old residential areas and the small space for elevator installation construction, there are significant construction safety hazards in the stacking of elevator installation accessories. To avoid these problems, a mode of pre-installing the whole elevator into a steel-frame shaftway has emerged. However, after the elevator is pre-installed into the steel-frame shaftway, the counterweight frame of the elevator also needs to be installed and shipped together with the whole steel-frame shaftway. Since the counterweight frame is a moving part during the operation of the elevator, it is difficult for general fixed parts to prevent the movement of the counterweight frame during transportation, resulting in easy damage to the counterweight frame during transportation.

Two counterweight guide rails are arranged vertically on the elevator steel frame through guide rail brackets, and the counterweight frame is slidably arranged between the two counterweight guide rails, and vertical beams are arranged on both sides of the counterweight frame; the counterweight frame fixing structure includes an inner plate arranged inside the counterweight guide rail and an outer plate arranged outside the counterweight guide rail. The inner plate is fixed on the vertical beam, the guide rail connecting plate is clamped into the counterweight guide rail and then fixedly connected with the outer plate, and the inner plate and the outer plate are detachably connected, so that the counterweight frame fixing structure fixes the counterweight frame relative to the counterweight guide rail.

[0006] As a further technical solution, the inner plate is arranged between the counterweight guide rail and the vertical beam, and a plurality of installation holes are penetrated and opened on the vertical beam for fixedly connecting the inner plate.

[0007] As a further technical solution, the cross-section of the counterweight guide rail is in a "several" shape, and fixing holes are penetrated and opened at the bottoms of both sides of the "several" shape. After the guide rail connecting plate extends into the counterweight guide rail, the guide rail connecting plate, the counterweight guide rail, and the outer plate are fixedly connected by fixing bolts.

[0008] As a further technical solution, double-headed screws are inserted through both sides of the inner plate and the outer plate for detachable connection in cooperation with bolts.

[0009] As a further technical solution, the inner plate and the outer plate form a fixed bracket. One side of the fixed bracket is fixedly connected to the vertical beam of the counterweight frame by the inner plate, and the other side of the fixed bracket is fixedly connected to the counterweight guide rail by the outer plate.

Detailed Embodiment

[0021] The following will introduce the present utility model in detail in conjunction with the drawings:

[0022] Embodiment: As shown in the appendix Figures 1 to 7 As shown, this prefabricated counterweight frame structure for a steel-frame elevator includes a counterweight frame 1, vertical beams 2, mounting holes 21, counterweight guide rails 3, fixing holes 31, a counterweight frame fixing structure 4, a fixing bracket 41, a double-headed screw 42, an inner plate 43, an outer plate 44, a guide rail connecting plate 5, fixing bolts 51, a guide rail bracket 6, and an elevator steel frame 7.

[0023] Refer to the appendix Figure 1 , two counterweight guide rails 3 are arranged vertically on the elevator steel frame 7, and the two counterweight guide rails 3 are fixed to the elevator steel frame 7 through the guide rail brackets 6. As Figure 2 , 4 shown, a counterweight frame 1 is slidably arranged between the two counterweight guide rails 3, and vertical beams 2 are arranged on both the left and right sides of the counterweight frame 1. The counterweight frame fixing structure 4 includes an inner plate 43 arranged inside the counterweight guide rails 3 and an outer plate 44 arranged outside the counterweight guide rails 3. Among them, the inner plate 43 is arranged between the counterweight guide rails 3 and the vertical beams 2, and a number of mounting holes 21 are penetrated through the vertical beams 2. The inner plate 43 is fixedly connected to the mounting holes 21 (vertical beams 2) by threaded connection.

[0024] Furthermore, as Figure 3 , 6 , 7 shown, the cross-section of the counterweight guide rail 3 is in a "ji" shape, and fixing holes 31 are penetrated through the bottom of both sides of the "ji" shape. After the guide rail connecting plate 5 extends into the counterweight guide rail 3, the guide rail connecting plate 5, the counterweight guide rail 3, and the outer plate 44 are fixedly connected by the fixing bolts 51. That is, after the guide rail connecting plate 5 is snapped into the counterweight guide rail 3, it is fixedly connected to the outer plate 44.
