Description

Technical Field

[0001] The invention belongs to the technical field of elevators, and in particular relates to a steel wire rope home elevator. Background Art

[0002] Elevator An elevator is a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rows of rigid rails that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line.

[0003] Under normal circumstances, an elevator is mainly composed of a motor, a car and a counterweight. For small home elevators (such as a 2-3-story villa), due to the relatively small load capacity and the relatively small installation space, a counterweight is generally not installed and a forced drive elevator is used.

[0004] The patent with publication number CN214935071U discloses a protection device for a small household elevator without counterweight, including a wire rope and a rope end plate. The end of the wire rope is connected to the rope end plate through a rope end assembly. The rope end assembly includes a limiting mechanism and a pull rod. The rope end plate is installed on the top crossbeam of the elevator car. The end of the wire rope is connected to the top of the limiting mechanism, and the bottom of the limiting mechanism is connected to the top of the pull rod. The bottom of the pull rod passes through the rope end plate and is arranged below the bottom surface of the rope end plate. It is characterized in that: two groups of bottom nuts are screwed to the bottom of the pull rod, and an upper nut is screwed to the middle of the pull rod. The top surface of the upper nut rests on the bottom surface of the rope end plate. A telescopic spring is sleeved on the pull rod, and the top of the telescopic spring rests on the bottom surface of the upper nut, and the bottom rests on the top surface of the upper bottom nut; a switch plate is installed on the pull rod between the two groups of bottom nuts, and a vertical plate is installed on the bottom surface of the rope end plate on the left side of the pull rod. Two groups of safety switches are provided on the vertical plate, and the left side of the switch plate is arranged between the two groups of safety switches.

[0005] However, its telescopic spring, safety switch, etc. are all arranged in the vertical direction, which occupies a relatively large space in the vertical direction, reducing the space for vertical movement of the car. Summary of the Invention

[0006] The object of the present invention is to provide a steel wire rope home elevator that can save the space occupied by the steel wire rope connection structure in the height direction.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a steel wire rope home elevator, a steel wire rope and a car, and further comprising:

[0008] A fixed base plate is fixed to the upper side of the car and is provided with a plurality of chutes that are evenly distributed around the axis of the fixed base plate.

[0009] Sliders, which correspond to the slide slots one by one, are slidably connected to the slide slots, each slide is hinged with a connecting rod, and a telescopic spring is installed between the slide and the slide slot;

[0010] Rope end plate, one end of each connecting rod away from the slider is hinged to the rope end plate, and one end of the wire rope is fixedly connected to the rope end plate;

[0011] The first safety switch and the second safety switch, wherein an extension rod is fixed on one of the sliders, the two mounting switches are fixed on the fixed base plate, and the extension rod is arranged between the first safety switch and the second safety switch.

[0012] Furthermore, a fixed shaft is fixed in each sliding groove, and a sliding hole for the fixed shaft to pass through is provided on the sliding block.

[0013] Furthermore, the telescopic spring is sleeved on the fixed shaft, and the telescopic spring is arranged between the sliding block and one side of the sliding groove close to the axis of the fixed base plate.

[0014] Furthermore, four slide grooves are provided, and the four slide grooves are evenly distributed around the axis of the fixed base plate.

[0015] Furthermore, it also includes a fixing rod, which is fixed on the fixed base plate, and is provided with a telescopic groove with an upward opening, in which a buffer top rod is inserted, and a first side connecting groove is provided on the side wall of the telescopic groove, and a buffer connecting rod is connected to the buffer top rod, one end of the buffer connecting rod passes through the first side connecting groove and is hinged to the buffer top rod, and the other end is hinged to one of the sliders.

[0016] Furthermore, it also includes a fixed frame, which is fixed on the fixed base plate. The fixed frame is provided with a transverse groove, a clamping rod is inserted in the transverse groove, and a clamping push rod is hinged on the clamping rod. A second side connecting groove is also provided on the side wall of the telescopic groove. The end of the clamping push rod away from the clamping rod passes through the second side connecting groove and is hinged to the buffer top rod. The clamping end of the clamping rod can abut against the elevator guide rail.

[0017] Furthermore, the clamping end is configured to be made of elastic material.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) After the elevator reaches the top, the motor still drives the drum to rotate and reel in the wire rope. The wire rope will pull the rope head plate upwards. The rope head plate drives the slider to move inwards of the chute through the connecting rod until the extension rod contacts the first safety switch. At this time, the elevator control device receives a signal and controls the motor to stop working.

[0020] (2) When the elevator car reaches the bottom, the drum continues to lower the wire rope, and the telescopic spring drives the slider to move to the outside of the slide until the extension rod contacts the second safety switch. At this time, the elevator control device receives a signal and controls the motor to stop working;

[0021] (3) The space occupied by the wire rope connection structure in the vertical direction is small;

[0022] (4) The buffer link can play a certain buffering role to prevent the car from rushing upward with excessive force;

[0023] (5) The clamping rod can prevent the car from continuing to rush upward due to inertia, reducing its impact on the building. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figures 1-8 The present invention provides a technical solution for a steel wire rope home elevator.

[0035] Example 1

[0036] A home elevator wire rope 1 connection structure, comprising the wire rope 1 and the car 2, further comprising:

[0037] A fixed base plate 3 is fixed to the upper side of the car 2 and is provided with a plurality of chutes 4, which are evenly distributed around the axis of the fixed base plate 3;

[0038] Slide blocks 5, which correspond to the slide slots 4 one by one, are slidably connected to the slide slots 4, and each slide block 5 is hinged with a connecting rod 6, and a telescopic spring 7 is installed between the slide block 5 and the slide slot 4;

[0039] Rope end plate 8, one end of each connecting rod 6 away from the slider 5 is hinged to the rope end plate 8, and one end of the wire rope 1 is fixedly connected to the rope end plate 8;

[0040] The first safety switch 9 and the second safety switch 10 , wherein an extension rod 11 is fixed on one of the sliders 5 , and the two mounting switches are fixed on the fixed base plate 3 , and the extension rod 11 is arranged between the first safety switch 9 and the second safety switch 10 .

[0041] A fixed shaft 12 is fixed in each slide groove 4 , and a sliding hole for the fixed shaft 12 to pass through is provided on the slider 5 .

[0042] The telescopic spring 7 is sleeved on the fixed shaft 12 , and the telescopic spring 7 is arranged between the sliding block 5 and a side of the sliding groove 4 close to the axis of the fixed base plate 3 .

[0043] In the event that the elevator's own safety switch fails, if the elevator car rises to the top and the motor is still driving the drum to rotate and reel in the wire rope 1, the tension applied to the wire rope 1 will become greater and greater, and the elevator car 2 will be unable to continue rising. In this way, the wire rope 1 will pull the rope end plate 8 to continue upward, and the rope end plate 8 will drive the slider 5 to move toward the inside of the slide groove 4 through the connecting rod 6 until the extension rod 11 contacts the first safety switch 9. At this time, the elevator control device receives a signal and controls the motor to stop working.

[0044] When the elevator car 2 reaches the bottom, the drum continues to lower the wire rope 1, and the telescopic spring 7 drives the slider 5 to move to the outside of the slide 4 until the extension rod 11 contacts the second safety switch 10. At this time, the elevator control device receives a signal and controls the motor to stop working.

[0045] Compared with existing mechanisms, the structure of the present invention occupies less space in the vertical direction.

[0046] Four slide grooves 4 are provided, and the four slide grooves 4 are evenly distributed around the axis of the fixed base plate 3 .

[0047] Example 2

[0048] On the basis of Example 1, the connection structure of the home elevator wire rope 1 also includes a fixed rod 13, which is fixed on the fixed base plate 3. The fixed rod 13 is provided with a telescopic groove 14 with an upward opening, and a buffer top rod 15 is inserted into the telescopic groove 14. The side wall of the telescopic groove 14 is provided with a first side connecting groove 16, and the buffer top rod 15 is connected to a buffer connecting rod 17. One end of the buffer connecting rod 17 passes through the first side connecting groove 16 and is hinged to the buffer top rod 15, and the other end is hinged to one of the sliders 5.

[0049] Then, if the elevator rises to the top, the upper end of the buffer link 17 first contacts the upper transverse beam at the top, and the buffer push rod 15 moves into the telescopic groove 14. The buffer push rod 15 drives the slider 5 to move inside the slide groove 4 through the buffer link 17, thereby driving the extension rod 11 to contact the first safety switch 9. The buffer link 17 can play a certain buffering role to prevent the car 2 from rushing upward with too much force.

[0050] Example 3

[0051] On the basis of Example 2, the connection structure of the wire rope 1 of the home elevator further includes a fixed frame 18, which is fixed to the fixed base plate 3. The fixed frame 18 is provided with a transverse groove 19, in which a clamping rod 20 is inserted. A clamping push rod 21 is hingedly connected to the clamping rod 20. A second side connection groove 22 is further provided on the side wall of the telescopic slot 14. The end of the clamping push rod 21 away from the clamping rod 20 passes through the second side connection groove 22 and is hingedly connected to the buffer push rod 15. The clamping end of the clamping rod 20 can abut against the elevator guide rail 23. The clamping end is set to an elastic material, such as elastic rubber.

[0052] When the elevator rises to the top, the upper end of the buffer link 17 first contacts the upper transverse beam at the top, and the buffer push rod 15 moves into the telescopic groove 14. The buffer push rod 15 drives the slider 5 to move toward the inside of the slide groove 4 through the buffer link 17, and at the same time moves toward the elevator guide rail 23 through the clamping push rod 21. In this way, the clamping end of the clamping rod 20 can slow down after contacting the elevator guide rail 23. When the elevator control device receives a signal and controls the motor to stop working, it can also prevent the car 2 from continuing to collide upward due to inertia, thereby reducing its impact on the building.

[0053] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
