Description

Technical Field

[0001] The present application relates to the technical field of elevators, and in particular to a main frame structure of a villa elevator. Background Art

[0002] The main frame and gantry of the elevator are important parts of the elevator. The main frame is the supporting structure of the elevator drive mainframe. It carries the elevator drive mainframe and its related components to ensure that they can operate stably and safely. The main function of the gantry is to support and guide the car to ensure that it can run up and down smoothly along the guide rail.

[0003] In the prior art, a main frame is installed at the top of the elevator shaft, and an elevator drive main frame and a traction wheel are respectively arranged on the main frame, and the elevator drive main frame provides a power source for the rotation of the traction wheel; the gantry includes a vertical frame, a horizontal top frame and a car bottom beam; the elevator car is installed between the two vertical frames and the car bottom beam; a mounting frame is arranged between the horizontal top frame and the car, and a sheave is arranged on the mounting frame, and a traction rope is arranged between the main frame and the gantry, one end of the traction rope is connected to the main frame, and the other end is successively wound around the sheave and the traction wheel and extends to the counterweight device, and the gantry is driven up and down by the rotation of the traction wheel to realize the lifting and lowering of the elevator car.

[0038] Reference Figure 2 , Figure 3 It should be noted that, in the present embodiment, except for the length difference between the main beam 1 and the auxiliary beam 2, the structure of the main beam 1 is the same as that of the auxiliary beam 2. The structure of the main beam 1 is described below as an example, and the structure of the auxiliary beam 2 can be obtained similarly; the main beam 1 includes two mounting bars 12, both of which are channel steels, and the two mounting bars 12 are arranged in parallel (that is, the two mounting bars 12 are parallel to each other), and the two mounting bars 12 are spaced apart to form an avoidance channel 11, and the avoidance channel 11 is used to avoid the horizontal top frame 81 in the gantry 8.

[0039] Reference Figure 2 , Figure 3A mounting piece 13 is provided between the two mounting bars 12, and the two mounting bars 12 are detachably connected through the mounting piece 13.

The length direction of the two second connecting bars 43 is perpendicular to the mounting bar 12 of the main beam 1. The two ends of the second connecting bar 43 are respectively welded and fixed to the two first connecting bars 42 to form the second connecting beam 4 in combination; in this embodiment, the second connecting bar 43 is a channel steel.

[0041] Reference Figure 2 , Figure 3 The first connecting beam 3 includes a third connecting bar 35 and a fourth connecting bar 36. Two third connecting bars 35 are provided and are spaced apart along the length direction of the main beam 1 (i.e., the length direction of the mounting bar 12).

[0042] Reference Figure 1 , Figure 2 , Figure 3It should be noted that, for the convenience of description, the gap between the two third connecting bars 35 is defined as the first penetration channel 31, the gap between the two second connecting bars 43 is defined as the second penetration channel 41, and the gap between the two mounting bars 12 in the sub-beam 2 is defined as the third penetration channel 21; wherein, the top walls of the two third connecting bars 35 are jointly installed with a mounting plate 32. In this embodiment, both sides of the mounting plate 32 are fixedly installed on the two third connecting bars 35 by welding. The mounting plate 32 is used for the installation of the traction rope 72. One end of the traction rope 72 is fixedly connected to the mounting plate 32, and the other end is penetrated through the first penetration channel 31 and wound around the rope wheel 83 in the gantry 8, then penetrated through the second penetration channel 41 and wound around the traction wheel 71, and then penetrated through the third penetration channel 21 and extended to the counterweight device (the counterweight device is a prior art structure, which will not be elaborated on here and is not shown in the figure).

[0043] The implementation principle of Example 1 of the present application is: the traction rope 72 is pulled by rotating the traction wheel 71, which can drive the gantry 8 to move up and down; when the gantry 8 is lifted to the top floor of the building along the elevator shaft, the transverse top frame 81 in the gantry 8 can be embedded in the avoidance channel 11, and the avoidance channel 11 provides an avoidance space for the transverse top frame 81, so that when the gantry 8 is lifted to a high position, the avoidance channel 11 can reduce the space occupancy rate of the combination of the main frame and the gantry 8 to the elevator shaft, thereby improving the space utilization rate of the elevator shaft; the mounting bar 12, the second connecting bar 43, and the third connecting bar 35 are all set to channel steel, which greatly improves the deformation resistance of the overall structure, thereby improving safety.

[0044] Embodiment 2:

[0045] The embodiment of the present application discloses a main frame structure of a villa elevator.

[0046] Reference Figure 4 , Figure 5 The main frame structure of the villa elevator disclosed in the embodiment of the present application is different from that of embodiment 1 in that:

[0047] In this embodiment, a sliding groove 33 is provided on the top wall of each third connecting bar 35, and both ends of the sliding groove 33 are extended along the length direction of the third connecting bar 35, and the mounting plate 32 is slidably installed between the sliding grooves 33 of the two third connecting bars 35; a positioning bar 34 is fixedly installed on the inner wall of each third connecting bar 35 close to the first through-channel 31, and both ends of the positioning bar 34 are extended along the length direction of the third connecting bar 35, and the top wall of the positioning bar 34 is kept flush with the bottom wall of the sliding groove 33; a plurality of positioning holes 341 are provided on the top wall of the positioning bar 34, and all the positioning holes 341 are spaced apart along the length direction of the positioning bar 34.

[0048] Reference Figure 4 , Figure 5 The positioning bar 34 is provided with a positioning piece 6, and the positioning piece 6 is used to fix the relative position between the mounting plate 32 and the sliding groove 33. In this embodiment, the positioning piece 6 includes a positioning column 61 and a return spring 62. The number of the positioning column 61, the return spring 62 and the positioning hole 341 is correspondingly arranged, and each positioning column 61 is slidably installed in the corresponding positioning hole 341; one end of the return spring 62 is fixedly connected to the inner wall of the corresponding positioning hole 341, and the other end is fixedly connected to the corresponding positioning column 61. The return spring 62 normally makes the positioning column 61 partially exposed in the positioning hole 341 and is used to block the side wall of the mounting plate 32. When the mounting plate 32 is placed in the sliding groove 33, the mounting plate 32 presses the positioning column 61 and makes the positioning column 61 move into the positioning hole 341.

[0049] The implementation principle of Example 2 of the present application is as follows: when the mounting plate 32 is installed, the mounting plate 32 is placed in the sliding grooves 33 of the two third connecting bars 35 according to the position of the rope pulley 83 of the mounting frame 82 in the gantry 8. The mounting plate 32 presses the positioning column 61 located below into the positioning hole 341 through its own weight. The positioning column 61 that is not pressed by the mounting plate 32 can be blocked by the side wall of the mounting plate 32, thereby limiting the mounting plate 32 to fix the relative position between the mounting plate 32 and the sliding groove 33, so that the mounting plate 32 can face the position of the rope pulley 83 of the mounting frame 82, thereby improving the adaptability of the overall structure.
