Technical Field
[0001] The invention relates to a backpack type household elevator. Background Art
[0002] At present, in order to maximize the utilization of space, home elevators generally adopt a backpack structure, which is very compact.
[0003] However, traditional backpack home elevators often fall suddenly when the rope breaks or fails, and such a fall often poses a huge safety hazard to people and objects in the car. Traditional elevators use centrifugal force to drive the brake to limit the clamping of the guide rail to buffer the car's fall, but the brake itself is also driven by rope pulling, and it is also possible that the rope breaks and the brake fails. For this reason, a buffer protection device needs to be set in the backpack home elevator. Summary of the invention

[0018] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.
[0019] The technical solution specifically implemented in the present invention is: In a specific embodiment, Figure 1 and Figure 2 As shown, the present invention provides a backpack-type home elevator, comprising an elevator shaft frame 1, a backpack frame arranged in the elevator shaft frame 1, and a car installed on the backpack frame; The backpack frame includes two vertical beams 2, and an upper beam and a lower beam 3 connected between the two vertical beams 2; A buffer protection device is provided at the bottom of the elevator shaft frame 1, and the buffer protection device includes a support plate 4 and two buffers arranged on the top of the support plate 4, the two buffers correspond to the two vertical beams 2 one by one, and each buffer is located directly below the corresponding vertical beam 2, and the buffer includes a support sleeve 5, and a pressure plate 6 is slidably connected inside the support sleeve 5, a buffer spring 7 is connected to the bottom of the pressure plate 6, and a support column 8 is connected to the top of the pressure plate 6, and the top of the support column 8 extends to the top of the support sleeve 5 and is connected to a contact plate 9.
[0020] The above scheme is adopted: by setting a buffer protection device, when the backpack frame falls, the bottom ends of the two vertical beams 2 of the backpack frame will hit the contact plate 9 respectively, so that the contact plate 9 drives the pressure plate 6 downward through the support column 8 and compresses the buffer spring 7. The buffer spring 7 absorbs the impact force to play a buffer protection role and reduce the safety damage to the people inside the car.
[0021] In another specific embodiment, Figure 2 , Figure 3 and Figure 4As shown, a bracket 10 is provided on the top of the support plate 4, and a horizontal screw rod 11 is rotatably connected to the bracket 10, and a slider 13 threadedly connected to the horizontal screw rod 11 is slidably connected to the bracket 10 through a slide rail 12, and a limit plug rod 14 is connected to the side of the slider 13, and a vertical bar hole for inserting the limit plug rod 14 is provided on the vertical beam 2, and a one-way rotating ratchet 15 is fixedly sleeved on the horizontal screw rod 11, and a pawl 16 cooperating with the one-way rotating ratchet 15 is hinged on the bracket 10, and the pawl 16 is used to keep the one-way rotating ratchet 15 in unidirectional rotation, and a mounting plate 17 is provided at the bottom of the lower beam 3, and the mounting plate 17 is connected with a vertical ratchet bar 18 that can engage or disengage with the one-way rotating ratchet 15.
[0022] The above scheme is adopted: when the bottom end of the vertical beam 2 collides with the contact plate 9, the vertical ratchet bar 18 connected to the bottom of the lower beam 3 will engage with the one-way rotating ratchet 15; in the process of the buffer spring 7 being compressed, the vertical ratchet bar 18 moves downward and drives the one-way rotating ratchet 15 to rotate, so that the one-way rotating ratchet 15 drives the horizontal screw rod 11 to rotate, and the horizontal screw rod 11 drives the slider 13 to move toward the vertical beam 2, and then the slider 13 drives the limit plug 14 to move and insert it into the vertical strip hole of the vertical beam 2; when the backpack frame rebounds upward, the vertical ratchet bar 18 will move upward at this time and cannot rotate the one-way rotating ratchet 15, so the slider 13 and the limit plug 14 will remain stationary, thereby preventing the backpack frame from continuing to rebound upward through the limit plug 14, so that the backpack frame stops quickly to avoid secondary damage to the people inside the car.
[0023] In another specific embodiment, Figure 4 As shown, the vertical ratchet bar 18 is connected to two horizontal slide bars 19 , and the horizontal slide bars 19 movably penetrate the mounting plate 17 . A return spring 20 sleeved on the horizontal slide bars 19 is connected between the mounting plate 17 and the vertical ratchet bar 18 .
[0024] With the above solution, when the vertical ratchet bar 18 moves downward, the return spring 20 will push the vertical ratchet bar 18 to maintain engagement with the one-way rotating ratchet 15 ; when the vertical ratchet bar 18 moves upward, the vertical ratchet bar 18 will squeeze the return spring 20 and disengage from the one-way rotating ratchet 15 .
[0025] In another specific embodiment, Figure 2 As shown, an elevator guide rail 21 is provided in the elevator shaft frame 1, and a guide shoe 22 that slidably cooperates with the elevator guide rail 21 is provided on the backpack frame.
[0026] In another specific embodiment, Figure 2 As shown, the outer sides of the two vertical beams 2 are respectively connected with fork frames 23 , the fork frames 23 are used to support and install the car, and the guide shoes 22 are connected to the outer sides of the fork frames 23 .
[0027] In another specific embodiment, Figure 1 As shown, a traction mechanism 24 is provided on the top of the elevator shaft frame 1, and a landing door device 25 is provided on the elevator shaft frame 1.
[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
