Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] The utility model provides Figure 1-3The shock-absorbing elevator guide rail buffer device shown is a shock-absorbing elevator guide rail buffer device, comprising a guide rail 2 and a pulley 3 arranged at the upper end of the guide rail 2; a first connecting plate 4 is connected to the upper end of the pulley 3; mounting blocks 10 are arranged at the left and right sides of the upper end of the first connecting plate 4; a shock-absorbing outer column 5 is installed at the upper end of the mounting block 10, and a shock-absorbing spring 12 is installed at the inner position of the shock-absorbing outer column 5; a shock-absorbing inner column 6 is connected to the inner part of the shock-absorbing outer column 5 and at the upper end of the shock-absorbing spring 12; a second connecting plate 7 is connected to the upper end of the shock-absorbing inner column 6; through the arrangement of the shock-absorbing outer column 5, the shock-absorbing inner column 6 and the shock-absorbing spring 12, a buffering and shock-absorbing effect is played between the second connecting plate 7 and the pulley 3.
[0028] like Figure 1 and Figure 2 As shown, in order to play a buffering and shock-absorbing role between the second connecting plate 7 and the pulley 2, when using the shock-absorbing elevator guide rail buffer device, the second connecting plate 7 is first fixedly connected to the elevator car, and then the pulley 3 is matched and connected with the elevator guide rail 2 on the wall of the elevator shaft. When the elevator car shakes, the second connecting plate 7 is squeezed toward the elevator guide rail 2, causing the shock-absorbing inner column 6 to shrink toward the inside of the shock-absorbing outer column 5, so that the shock-absorbing spring 12 inside the shock-absorbing outer column 5 plays a shock-absorbing and buffering role between the second connecting plate 7 and the pulley 3, effectively reducing the impact caused by the pulley 3 and the elevator guide rail 2. Through the setting of the shock-absorbing outer column 5, the shock-absorbing inner column 6 and the shock-absorbing spring 12, the second connecting plate 7 and the pulley 2 play a buffering and shock-absorbing role, avoiding the impact caused by the pulley 3 and the elevator guide rail 2 to affect the human body, thereby allowing the elevator to run smoothly.
[0029] A limiting plate 1 is installed at the upper end of the guide rail 2 and at the front and rear sides of the pulley 3. The limiting plate 1 and the guide rail 2 are fixedly connected by welding. Both the limiting plate 1 and the guide rail 2 are made of stainless steel. The setting of the limiting plate 1 can play a limiting role on the pulley 3.

Through the setting of the limiting plate 1, the pulley 3 can be limited to prevent the pulley 3 from slipping and affecting the normal operation of the elevator, so that the shock-absorbing elevator guide rail buffer device can be better used.

At the same time, the second connecting plate 7 is squeezed to impact the shock-absorbing pad 8, and the rubber plate 13 and the steel plate 14 inside the shock-absorbing pad 8 are squeezed by the second connecting plate 7 and shrink inward, thereby strengthening the buffering effect between the second connecting plate 7 and the pulley 3. By setting the shock-absorbing pad 8, the rubber plate 13 and the steel plate 14, the shock-absorbing effect between the second connecting plate 7 and the pulley 3 can be further increased, so that the shock-absorbing elevator guide rail buffer device can be better used.
[0033] A first mounting plate 9 is provided at the lower end of the shock-absorbing pad 8 and at the upper end of the first connecting plate 4. A second mounting plate 11 is connected to the lower end of the shock-absorbing outer column 5 and the upper end of the shock-absorbing inner column 6. The first mounting plate 9 is a rectangular structure, and the second mounting plate 11 is a disc structure. The first mounting plate 9 and the first connecting plate 4 are fixedly connected by fastening nuts, and the second mounting plate 11 and the mounting block 10 and the second connecting plate 7 are fixedly connected by fastening nuts.
[0034] like Figure 2 and Figure 3As shown, in order to facilitate the installation and disassembly of the shock-absorbing pad 8, the shock-absorbing outer column 5 and the shock-absorbing inner column 6, when using the shock-absorbing elevator guide rail buffer device, the second mounting plate 11 is first connected to the lower end of the shock-absorbing outer column 5 and the upper end of the shock-absorbing inner column 6 respectively, and then the shock-absorbing pad 8 is glued to the first mounting plate 9, and then the shock-absorbing outer column 5 and the shock-absorbing inner column 6 are connected through the shock-absorbing spring 12, and then the second mounting plate 11 is fixed to the upper end of the mounting block 10 and the lower end of the first connecting plate 4 through the fastening nut, and then the shock-absorbing pad 8 is fixed to the upper end of the second connecting plate 7 through the first mounting plate 9 and the fastening nut.
