[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0033] Reference Figure 1-Figure 3The top of the support plate 1 is fixedly connected to a fence 3, and the fence 3 here is used to ensure the safety of the workers. The top of the fence 3 is fixedly connected to a support plate 2, and the fence 3 here plays a supporting and fixing role for the support plate 2. The four sides of the support plate 1 and the support plate 2 are fixedly connected to slide wheels 4, and the slide wheels 4 that are urged are used to cooperate with the hoist cage to lift the elevator. The front end of the fence 3 is slidably connected to a gate 5, and the bottom end of the gate 5 contacts the top of the support plate 1, and the outer wall of the support plate 1 and the support plate 2 are fixedly connected to an outer plate 6, and the inner wall of the outer plate 6 is slidably connected to an inner plate 7, and the outer plate 6 here provides a stable sliding space for the inner plate 7;

[0034] The inner wall of the inner plate 7 is fixedly connected to the limit plate 8, and the limit plate 8 here is used to prevent the inner plate 7 from leaving the sliding range of the outer plate 6. The outer side of the limit plate 8 is slidably connected to the inner wall of the outer plate 6. The four corners of the inner wall of the outer plate 6 are fixedly connected with dampers 9. The dampers 9 here can resist the impact force of a part of the inner plate 7 hitting the inner wall of the cage. The outer side wall of the damper 9 is fixedly connected to the inner wall of the limit plate 8. The inner wall of the outer plate 6 is rotatably connected to a plurality of rotating rods 10. When the inner plate 7 is subjected to pressure, the rotating rod 10 can rotate around the fulcrum connected to the inner wall of the outer plate 6. One end of the rotating rod 10 It is slidingly connected to the inner wall of the limit plate 8, and the inner wall of the rotating rod 10 is movably connected with a ball 11. The inner wall of the limit plate 8 is fixedly connected with an inner column 12. The limit plate 8 here supports and fixes the inner column 12. The inner wall of the outer plate 6 is provided with multiple springs 13. The spring 13 here is used to assist the damper 9 in resisting the impact force, thereby improving the anti-collision performance of this elevator. One end of the spring 13 is fixedly connected to the outside of the ball 11, and the other end of the spring 13 is fixedly connected to the inner wall of the inner column 12. The ball 11 and the inner column 12 here support and fix the spring 13.

[0035] Reference Figure 4-Figure 6The front end of the first supporting plate 1 is rotationally connected with a partition assembly for additional extension, which is used to be placed on the working platform at the stop position of the elevator. The partition assembly comprises a hanging plate 14, the inner side wall of which is rotationally connected with the front end of the first supporting plate 1, which serves as a support for the hanging plate 14. The left and right sides of the hanging plate 14 are slidingly connected with the inner wall of the fence 3. The outer side walls of the hanging plate 14 are rotationally connected with supporting blocks 15, which can rotate around the outer side walls of the hanging plate 14. The supporting blocks 15 are fixedly connected with slide columns 16 on one side, which can move together with the supporting blocks 15 when the supporting blocks 15 rotate. The slide columns 16 are in a clamping relationship with the fence 3. When the slide columns 16 slide out of the clamping range of the fence 3, the hanging plate 14 can be lowered. The top front side of the first supporting plate 1 is rotationally connected with a pull rope assembly for clamping with the partition assembly. The pull rope assembly comprises a rubber block 17, the surface of which is provided with patterns for increasing friction.

[0036] The bottom end of the rubber block 17 is fixedly connected with a wire ring 18, which can rotate when the rubber block 17 rotates. The outer side of the wire ring 18 is rotationally connected with the front end inner wall of the first supporting plate 1. The front end inner wall of the first supporting plate 1 is slidingly connected with two clamping blocks 19, which are in a clamping relationship with the hanging plate 14. When the hanging plate 14 is lowered, it will press the clamping blocks 19 to retract into the inner wall of the first supporting plate 1, thereby completing the clamping. The outer side of the clamping blocks 19 is fixedly connected with a limiting block 20, which can prevent the clamping blocks 19 from leaving the sliding range of the first supporting plate 1. The outer side of the limiting block 20 is slidingly connected with the front end inner wall of the first supporting plate 1. The inner side wall of the clamping blocks 19 is fixedly connected with a plastic-coated steel wire rope 21, which is in a traction state. Therefore, when the wire ring 18 rotates, it will increase the traction force of the plastic-coated steel wire rope 21, thereby pulling the clamping blocks 19 to separate from the clamping with the first supporting plate 1. At this time, the hanging plate 14 can be lifted again. One end of the plastic-coated steel wire rope 21 is fixedly connected with the inner wall of the wire ring 18.

[0037] Working principle: The staff can control the cage to perform the lifting operation of the construction elevator with the help of the slide wheel 4. When the elevator reaches the designated position and stops, the support block 15 can be rotated first to drive the slide column 16 to rotate, so that the slide column 16 can be disengaged from the fence 3. At this time, the hanging plate 14 can be lowered. At the same time, when the hanging plate 14 is parallel to the support plate 1, the hanging plate 14 here will squeeze the block 19 to retract it into the inner wall of the support plate 1. Because the plastic-coated steel wire rope 21 here is in a traction state, after the hanging plate 14 is completely flat, the block 19 here will quickly complete the engagement with the hanging plate 14. The limit block 20 here ensures that the block 19 will not leave the sliding range of the support plate 1. At this time, the elevator is fixed, which effectively increases the overall stability of the elevator when it stops. When the hanging plate 14 needs to be lifted, the rubber block 17 can be stepped on and then rotated to drive the wire ring 18 to rotate, thereby pulling the plastic-coated steel wire rope 21. At this time, the plastic-coated steel wire rope 21 will pull the clamping block 19 to disengage it from the hanging plate 14, and then the hanging plate 14 can be lifted.

[0038] When the elevator is lifted to the top or bottom, the inner plate 7 is first stressed and then transfers the force to the limit plate 8. The damper 9 contracts, providing a reaction force. At the same time, the rotating rod 10 rotates around the fulcrum connected to the inner wall of the outer plate 6 under the pressure of the limit plate 8, and drives the ball 11 to stretch to both sides. At this time, the distance between the inner column 12 and the ball 11 increases, thereby stretching the spring 13, thereby cooperating with the damper 9 to achieve a double relief of the impact force. Compared with a simple buffer plate, this design structure has a more obvious impact resistance effect and a longer service life, reducing the cost of frequent maintenance.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
