[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] (1) Fixed seats are installed on both sides of the top of the upper support frame, and mounting plates are installed on the surface of the fixed seats. When the electric hydraulic cylinder on the surface of the mounting plate is extended, it drives the linkage rod at the telescopic end to move on the top of the support rod. The linkage rod rises and drives the middle hinged top rod to rise accordingly. The top rod rises and swings along through the swing arm on the top of one of the calipers. The swing of the swing arm drives the other caliper to move closer through the pull rod, so that the two calipers on the surface of the mounting plate are close to each other. The close proximity of the calipers drives the friction block in the middle to contact and clamp the sliding guide rail. The clamping of the friction block and the sliding guide rail has a deceleration effect, so that the upper support frame slows down its falling speed. As the contact area between the friction block and the sliding guide rail increases, the car is finally fixed to the surface of the sliding guide rail by the caliper, causing the car to stop falling and avoid injury to passengers.
[0017] (2) The rotation of the servo motor on the top of the mounting seat drives the speed regulating gearbox at the output end to rotate. The speed regulating gearbox is convenient for realizing different speed operation according to whether the car is empty or loaded. A winding roller is installed at the output end of the speed regulating gearbox. The rotation of the winding roller makes the steel cable wound on the surface to be retracted and released, thereby driving the upper support frame to follow the lifting and lowering, so that the car can move up and down. The limit rings at both ends of the winding roller can prevent the steel cable from falling off the roller during the winding process. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.
[0041] See also Figure 1 - Figure 5 , an elevator with an anti-falling assembly, comprising: a frame assembly 1 and an anti-falling assembly 2;
[0042] See also Figure 1 , Figure 2 The frame assembly 1 includes a mounting frame 101, and sliding guide rails 102 are fixedly installed on both sides of the inner wall of the mounting frame 101. An upper support frame 103 is slidably installed on the surface of the sliding guide rails 102. A lower support frame 104 is slidably installed on the surface of the sliding guide rails 102 at the bottom of the upper support frame 103, and a car 105 is installed in the middle of the upper support frame 103 and the lower support frame 104.
[0043] During specific use: the sliding guide rail 102 installed on the inner wall of the installation frame 101 provides support for the lifting of the car 105. The car 105 is connected to the sliding guide rail 102 through the upper support frame 103 at the top and the lower support frame 104 at the bottom, so as to facilitate the stable operation of the car 105.
[0044] See also Figure 1 , Figure 3The anti-fall component 2 includes a fixed seat 201 installed on both sides of the top of the upper support frame 103, a mounting plate 202 is installed on the top of the fixed seat 201, and an electric hydraulic cylinder 203 is hingedly installed on the surface of the mounting plate 202. A support rod 204 is installed on one side of the surface of the mounting plate 202, and a linkage rod 205 is hinged on the top of the support rod 204. One end of the linkage rod 205 is hinged to the telescopic end of the electric hydraulic cylinder 203, and the middle part of the linkage rod 205 is hinged to a push rod 206. A group of calipers 207 are hingedly installed in the middle of the surface of the mounting plate 202, and friction blocks 208 are fixedly installed inside the two calipers 207. The sliding guide rail 102 is inserted in the middle of the friction block 208. A swing arm 209 is hinged on the top of one of the calipers 207, and the push rod 206 is hinged to the swing arm 209. A pull rod 210 is installed in the middle of the swing arm 209, and one end of the pull rod 210 is connected to the top of the other caliper 207.
[0045] When in use, fixed seats 201 are installed on both sides of the top of the upper support frame 103, and mounting plates 202 are installed on the surface of the fixed seats 201. When the electric hydraulic cylinder 203 on the surface of the mounting plate 202 is extended, it drives the linkage rod 205 at the telescopic end to move on the top of the support rod 204. The linkage rod 205 rises and drives the middle hinged push rod 206 to rise accordingly. The push rod 206 rises and swings along through the swing arm 209 on the top of one of the calipers 207. The swing arm 209 swings and drives the other caliper 207 through the pull rod 210. 7 moves closer, so that the two calipers 207 on the surface of the mounting plate 202 come closer, and the caliper 207 approaches and drives the friction block 208 in the middle to contact and clamp the sliding guide rail 102. The clamping of the friction block 208 and the sliding guide rail 102 has a deceleration effect, thereby slowing down the falling speed of the upper support frame 103. As the friction block 208 is clamped and the contact area with the sliding guide rail 102 increases, the car 105 is finally fixed to the surface of the sliding guide rail 102 by the caliper 207, causing the car 105 to stop falling, thereby preventing passengers from being injured.
[0046] See also Figure 5 A mounting base 3 is fixedly installed on the top of the frame assembly 1, a servo motor 4 is fixedly installed on the top of the mounting base 3, a speed regulating gear box 5 is fixedly installed on the output end of the servo motor 4, a winding roller 6 is fixedly installed on the output end of the speed regulating gear box 5, a steel cable 7 is wound around the surface of the winding roller 6, one end of the steel cable 7 is fixedly connected to the top of the upper support frame 103, and a limit ring 61 is installed at both ends of the winding roller 6.
[0047] During specific use: the servo motor 4 on the top of the mounting seat 3 rotates to drive the speed regulating gearbox 5 at the output end to rotate. The speed regulating gearbox 5 is convenient for realizing different speed operation according to whether the car 105 is unloaded or manned. A winding roller 6 is installed at the output end of the speed regulating gearbox 5. The rotation of the winding roller 6 makes the steel cable 7 wound on the surface retract and release, thereby driving the upper support frame 103 to follow the lifting and lowering, so that the car 105 can move up and down. The limit rings 61 at both ends of the winding roller 6 can prevent the steel cable 7 from falling off the roller during the winding process.

[0049] During specific use: connecting plates 8 are installed on both sides of the upper support frame 103, and the speed sensor 9 on the surface of the connecting plate 8 corresponds to the sliding guide rail 102. When the car 105 falls rapidly or hits the top, the speed sensor 9 detects the speed abnormality, which facilitates the transmission of the signal to the elevator control box, thereby performing emergency braking.
[0050] See also Figure 2 , Figure 4 A connecting seat 10 is fixedly installed on one side of the upper support frame 103, and an I-shaped groove 11 is provided on the surface of the connecting seat 10. A locking rod 12 is slidably installed inside the connecting seat 10, and a handle 13 is installed on the surface of the locking rod 12. The handle 13 slides inside the I-shaped groove 11. Fixed plates 14 are installed on both sides of the outer wall of the installation frame 101, and a socket 15 is provided on the surface of the fixing plate 14.

The locking rod 12 is limited inside the I-shaped groove 11 by a handle 13 installed on the surface. When maintenance is required, the car 105 stops inside the elevator shaft, and the personnel drives the locking rod 12 through the through hole 15 on the surface of the fixed plate 14 through the handle 13, so that the locking rod 12 plays a role of fixing and limiting, and manually locks the car 105 to prevent the car 105 from falling.
[0052] See also Figure 2 A counterweight mounting frame 16 is further provided on one side of the mounting frame 101 and runs relative to the car 105 .
[0053] During specific use: a counterweight mounting frame 16 is provided on one side of the mounting frame 101, and the counterweight block is placed inside the counterweight mounting frame 16.

[0056] Fixed seats 201 are installed on both sides of the top of the upper support frame 103, and mounting plates 202 are installed on the surface of the fixed seats 201. When the electric hydraulic cylinder 203 on the surface of the mounting plate 202 is extended, it drives the linkage rod 205 at the telescopic end to move on the top of the support rod 204. The linkage rod 205 rises and drives the middle hinged top rod 206 to rise accordingly. The top rod 206 rises and swings along through the swing arm 209 on the top of one of the calipers 207. The swing of the swing arm 209 drives the other caliper 207 to move through the pull rod 210. The two calipers 207 on the surface of the mounting plate 202 are brought closer together, and the caliper 207 approaches to drive the friction block 208 in the middle to contact and clamp the sliding guide rail 102. The clamping of the friction block 208 and the sliding guide rail 102 has a deceleration effect, thereby slowing down the falling speed of the upper support frame 103. As the friction block 208 is clamped and the contact area with the sliding guide rail 102 increases, the car 105 is finally fixed to the surface of the sliding guide rail 102 by the caliper 207, causing the car 105 to stop falling, thereby avoiding injury to passengers.
