Detailed Description
The following describes the embodiments of the present invention further with reference to the drawings and examples. The following examples are only for more clearly illustrating the technical aspects of the present invention, and are not intended to limit the scope of the present invention.
The technical scheme of the invention is as follows:
In one embodiment, as shown in fig. 1 and 2, the present invention provides a knapsack type home elevator, comprising an elevator derrick 1, a knapsack frame arranged in the elevator derrick 1, and a car mounted on the knapsack frame;
the backpack frame comprises two vertical beams 2, and an upper beam and a lower beam 3 connected between the two vertical beams 2;
The bottom of elevator derrick 1 is equipped with buffering protection device, buffering protection device includes backup pad 4 and sets up two buffers at backup pad 4 top, two buffers and two vertical beams 2 one-to-one, and each buffer is located the corresponding vertical beam 2 under, and the buffer includes support sleeve 5, support sleeve 5's inside sliding connection has clamp plate 6, clamp plate 6's bottom is connected with buffer spring 7, and clamp plate 6's top is connected with support column 8, support column 8's top extends to support sleeve 5's top and is connected with contact plate 9.
By adopting the scheme, when the backpack frame falls, the bottom ends of the two vertical beams 2 of the backpack frame respectively strike the contact plate 9, so that the contact plate 9 drives the pressing plate 6 to move downwards through the support columns 8 and compress the buffer springs 7, and the buffer springs 7 absorb the striking force, thereby playing the role of buffer protection and reducing the safety injury to personnel in the lift car.
In another specific embodiment, as shown in fig. 2,3 and 4, the top of the supporting plate 4 is provided with a bracket 10, a horizontal screw rod 11 is rotatably connected to the bracket 10, a sliding block 13 in threaded connection with the horizontal screw rod 11 is slidably connected to the bracket 10 through a sliding rail 12, a limit inserting rod 14 is connected to the side portion of the sliding block 13, a vertical bar-shaped hole for inserting the limit inserting rod 14 is formed in the vertical beam 2, a unidirectional rotating ratchet 15 is fixedly sleeved on the horizontal screw rod 11, a pawl 16 matched with the unidirectional rotating ratchet 15 is hinged to the bracket 10, the pawl 16 is used for enabling the unidirectional rotating ratchet 15 to rotate unidirectionally, a mounting plate 17 is arranged at the bottom of the lower beam 3, and a vertical ratchet bar 18 capable of being meshed with or separated from the unidirectional rotating ratchet 15 is connected to the mounting plate 17.
The technical scheme is that when the bottom end of the vertical beam 2 collides with the contact plate 9, the vertical ratchet bar 18 connected with the bottom of the lower beam 3 is meshed with the unidirectional rotation ratchet wheel 15, the vertical ratchet bar 18 moves downwards and drives the unidirectional rotation ratchet wheel 15 to rotate in the process that the buffer spring 7 is compressed, the unidirectional rotation ratchet wheel 15 drives the horizontal screw rod 11 to rotate, the horizontal screw rod 11 drives the sliding block 13 to move towards the vertical beam 2, the sliding block 13 drives the limit inserting rod 14 to move and be inserted into a vertical strip-shaped hole of the vertical beam 2, when the knapsack frame rebounds upwards, the vertical ratchet bar 18 moves upwards and cannot rotate the unidirectional rotation ratchet wheel 15, so that the sliding block 13 and the limit inserting rod 14 keep motionless, the knapsack frame is prevented from rebounds upwards continuously through the limit inserting rod 14, the knapsack frame is stopped rapidly, and secondary injury to personnel in a lift car is avoided.
In another specific embodiment, as shown in fig. 4, the vertical ratchet bar 18 is connected with two horizontal sliding bars 19, the horizontal sliding bars 19 movably penetrate through the mounting plate 17, and a return spring 20 sleeved on the horizontal sliding bars 19 is connected between the mounting plate 17 and the vertical ratchet bar 18.
