Description

Technical Field

[0001] The utility model relates to the technical field of elevator compensation chains, in particular to an energy-absorbing elevator balance compensation chain guide device. Background Art

[0002] When an elevator is in operation, the car is connected to the counterweight on the opposite side via a wire rope. When the car is at the top floor, the wire rope is on the counterweight side, adding to the weight of the wire rope. When the car is at the bottom floor, the wire rope is on the car side, adding to the weight of the wire rope. As the elevator continuously moves up and down, the wire rope will produce dynamic imbalance. Therefore, a compensating chain is needed to compensate for the weight of the wire rope, balance this difference, and ensure smooth operation. Currently, in elevators with vertical lift distances greater than 30 meters, the compensating chain is a critical device to ensure operational stability and safety. The elevator's up and down movement causes the compensating chain to move up and down. Due to the compensating chain's inherent flexibility, it will produce a certain degree of horizontal sway during the up and down movement, interfering with other elevator components, generating noise and excessive vibration.

[0026] 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.

[0027] See also Figure 1-7 The utility model provides an embodiment of an energy-absorbing elevator balancing and compensating chain guide device, comprising a connecting panel 1 and a balancing and compensating chain body 6. An anti-sway component 2 is provided on the right side of the connecting panel 1. The right end of the anti-sway component 2 is connected to a guide block 5. The balancing and compensating chain body 6 is provided inside the guide block 5. The outer side of the balancing and compensating chain body 6 is wrapped with a protective cover 7. The bottom of the guide block 5 is rotatably connected to four sets of guide rollers 9 via a rotating shaft 8.

[0028] The anti-sway assembly 2 includes a first connecting tube 21, a second connecting tube 22, a fixing rod 23, a first abutment plate 24, a first spring 25, a second abutment plate 26, and a second spring 27. The first connecting tube 21 is connected to the right side of the connecting panel 1, the second connecting tube 22 is provided at the right end of the first connecting tube 21, the fixing rod 23 is provided at the center of the first connecting tube 21, the first abutment plate 24 is provided at the bottom of the fixing rod 23, the first spring 25 is provided in the second connecting tube 22, the second abutment plate 26 is provided at the top end of the second connecting tube 22, and the second spring 27 is provided in the first connecting tube 21;

[0029] This device solves the problem that the balancing compensation chain shakes more due to load and other reasons, and the hard collision between the balancing compensation chain and the guide device will be larger, resulting in more collisions, noise and vibration, by setting up the anti-sway component 2, the buffer component 3 and the guide component 4.

[0030] Furthermore, two sets of cleaning components 10 are provided on both sides of the protective cover 7 in the guide block 5. The cleaning components 10 include a fixed groove 101, a movable rod 102, a brush plate 103 and a third spring 104. Two sets of fixed grooves 101 are symmetrically provided in the guide block 5. The movable rod 102 is movably connected in the fixed groove 101. The inner end of the movable rod 102 is fixedly connected to the brush plate 103. The brush plate 103 is semicircular and has a brush provided on the inner wall. The third spring 104 is provided in the fixed groove 101. The two ends of the third spring 104 are respectively against the inner wall of the movable rod 102 and the fixed groove 101. Figure 5 As shown, this structure is used when the balancing compensation chain main body 6 and the protective sleeve 7 pass through the guide block 5. Under the elastic action of the third spring 104, the brush plates 103 on both sides are attached to the surface of the protective sleeve 7. The brush inside the brush plate 103 is slid through the protective sleeve 7 to clean the outer surface of the protective sleeve 7, thereby reducing friction and making the balancing compensation chain main body 6 and the protective sleeve 7 run more smoothly.

[0031] Furthermore, the left end of the first connecting tube 21 is connected to the connecting panel 1, the second connecting tube 22 is movably connected to the first connecting tube 21, the lower end of the fixing rod 23 is inserted into the second connecting tube 22, the upper end of the first abutment plate 24 is fixedly connected to the fixing rod 23, the two ends of the first spring 25 are respectively against the first abutment plate 24 and the inner wall of the second connecting tube 22, the lower end of the second abutment plate 26 is fixedly connected to the second connecting tube 22, and the two ends of the second spring 27 are respectively against the second abutment plate 26 and the inner wall of the first connecting tube 21. Figure 4As shown, through the setting of the anti-sway component 2, when the balance compensation chain body shakes, the first connecting tube 21 and the second connecting tube 22 slide relative to each other, the first abutment plate 24 squeezes the first spring 25, and the second abutment plate 26 squeezes the second spring 27. The first spring 25 and the second spring 27 buffer the impact force generated by the shaking, thereby improving the protection effect.

[0032] Furthermore, a buffer assembly 3 is provided on the outside of the first connecting tube 21. The buffer assembly 3 includes a first connecting plate 31, a second connecting plate 32, an arc-shaped elastic plate 33, an elastic bellows 34 and a vent 35. The first connecting plate 31 is fixedly connected to the outside of the first connecting tube 21, and the second connecting plate 32 is fixedly connected to the outside of the second connecting tube 22. An arc-shaped elastic plate 33 is connected between the first connecting plate 31 and the second connecting plate 32. Two groups of elastic bellows 34 are connected to the opposite sides of the first connecting plate 31 and the second connecting plate 32. Several groups of vents 35 are evenly spaced in the elastic bellows 34. Figure 6 As shown, the structure is used to set up the buffer component 3. When the first connecting tube 21 and the second connecting tube 22 slide relative to each other, the distance between the first connecting plate 31 and the second connecting plate 32 changes, the bending degree of the arc-shaped elastic plate 33 changes, and the elastic bellows 34 expands and contracts. The arc-shaped elastic plate 33 and the elastic bellows 34 buffer the impact force again, which significantly improves the protection effect. Moreover, when the elastic bellows 34 is compressed, the air inside it is quickly ejected through the vent 35. When the elastic bellows 34 stretches and resets, external air enters it through the vent 35, which can convert the impact force received into kinetic energy of the air, thereby improving the buffering effect.

[0033] Furthermore, a guide assembly 4 is provided in the first connecting tube 21. The guide assembly 4 includes a guide rod 41, a guide groove 42, a first protrusion 43, and a second protrusion 44. Two sets of guide rods 41 are fixedly connected to the interior of the first connecting tube 21. Two sets of guide grooves 42 adapted to the guide rods 41 are provided in the second support plate 26. Several first protrusions 43 are equidistantly connected to the outer surface of the guide rod 41. A second protrusion 44 is equidistantly fixedly connected to the inner wall of the guide groove 42 on the side opposite to the guide rod 41. The first protrusion 43 and the second protrusion 44 are hemispherical and elastic. Figure 7 As shown, this structure is used when the first connecting tube 21 and the second connecting tube 22 slide relative to each other. The second support plate 26 slides along the guide rod 41 through the guide groove 42, and the first protrusion 43 and the second protrusion 44 generate intense friction, which can buffer the impact force and further improve the protection effect.

[0034] Furthermore, the guide block 5 is fixedly connected with a protective block 11 on all sides, and the protective block 11 is semi-cylindrical. Figure 3As shown, this structure is used to prevent the outer surface of the protective sleeve 7 from being worn when the protective sleeve 7 contacts the guide block 5 through the protective block 11.

[0035] Furthermore, the protective cover 7 is made of rubber material. Figure 2 As shown, the structure is used to protect the anchor chain, reduce wear and tear, and reduce noise during operation through the protective cover 7.

[0036] Working principle: When in use, the balancing compensation chain body 6 and the protective sleeve 7 pass through the guide block 5 and are guided by the four sets of guide rollers 9 inside the guide block 5. When the protective sleeve 7 passes through the guide block 5, the brush plates 103 on both sides are elastically acted upon by the third spring 104, so that the brush plates 103 are attached to the surface of the protective sleeve 7. The brush inside the brush plate 103 slides through the protective sleeve 7 to clean the outer surface of the protective sleeve 7, thereby reducing friction and making the balancing compensation chain body 6 and the protective sleeve 7 run more smoothly. Figure 4 As shown, when the balancing and compensating chain body 6 shakes, the first connecting tube 21 and the second connecting tube 22 slide relative to each other, the first abutting plate 24 presses the first spring 25, and the second abutting plate 26 presses the second spring 27. The first spring 25 and the second spring 27 buffer the impact force generated by the shaking, as shown in FIG. Figure 6 As shown, when the first connecting tube 21 and the second connecting tube 22 slide relative to each other, the distance between the first connecting plate 31 and the second connecting plate 32 changes, the bending degree of the arc-shaped elastic plate 33 changes, the elastic bellows 34 expands and contracts, and the arc-shaped elastic plate 33 and the elastic bellows 34 buffer the impact force again, which significantly improves the protection effect. Moreover, when the elastic bellows 34 is compressed, the air inside it is quickly ejected through the vent 35. When the elastic bellows 34 is extended and reset, the external air enters the inside through the vent 35, which can convert the impact force received into kinetic energy of the air. At the same time, as shown in FIG. Figure 7 As shown, the second abutment plate 26 slides along the guide rod 41 through the guide groove 42, and the first protrusion 43 and the second protrusion 44 generate intense friction, which can buffer the impact force. The above is the entire working principle of the utility model.
