Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an elevator steel rope anti-slip groove pulley and a device. Background Art

[0002] Traditional wire rope anti-slip groove devices basically install baffles or bars on the wheel beam and are arranged at the bottom of the wheel. The baffles or bars maintain a relatively small gap with the sheave and the wire rope to prevent the wire rope from slipping out of the groove. These baffles or bars are directly installed on the crossbeam, have no direct contact with the sheave, and do not form an anti-slip structure with the sheave. Therefore, one problem that this structure cannot solve is that when the sheave bearing is damaged and the sheave tilts, the gap between the sheave and the baffles or bars becomes larger after the sheave tilts, and the wire rope can still slip out of the sheave. At this time, the baffles or bars cannot play an anti-slip role. After the wire rope slips out of the sheave, it may cause the wire rope to wear off the shaft or pull the shaft out of the crossbeam, resulting in serious safety accidents. Therefore, we need to propose an elevator wire rope anti-slip groove sheave and device to solve the above-mentioned problems, which can effectively prevent the wire rope from slipping out of the sheave, avoid further damage to the wire rope, i.e., the sheave, and avoid safety accidents.

[0024] 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.

[0025] Example 1

[0026] See also Figure 1-6 The utility model provides a technical solution: an elevator wire rope anti-slip groove pulley and device, comprising a main baffle 1 and a sheave body mounted on the main baffle 1, wherein a rope groove is provided on the sheave body, and the main baffle 1 comprises a base 11 and an anti-slip plate 12 fixed to the upper end of the base 11 and arranged in an arc shape and matching the circular outer contour of the sheave body, and an anti-slip hook mechanism that can prevent the wire rope from slipping out of the groove is provided between the two sides of the anti-slip plate 12 and the main baffle 1, and a limiting space 5 is formed between the anti-slip plate 12, the anti-slip hook mechanism and the sheave body, and a gap of 2-3 mm is maintained between the anti-slip plate 12 and the wire rope on the sheave body. When the wire rope jumps, the main baffle 1 can effectively prevent the wire rope from slipping out of the groove.

[0027] Through the cooperation of the rope pulley body, the main baffle 1 and the anti-unhooking mechanism, the structure is simple, the installation is convenient, the cost is low, and it is safe and reliable. At the same time, the anti-unhooking mechanism, the anti-unhooking plate 12 and the rope pulley body constitute a limited space 5. Even if the wire rope escapes from the rope groove, it will not escape from the limited space 5, effectively preventing the wire rope from escaping from the rope pulley. At the same time, it has the function of detecting the wire rope escaping from the groove, avoiding further damage to the wire rope.

[0028] The anti-unhooking mechanism includes a first anti-unhooking hook 14 fixed on both sides of the anti-unhooking plate 12 and a second anti-unhooking hook 21 installed on the rope pulley body, the first anti-unhooking hook 14 is provided with a first card slot 15, and the second anti-unhooking hook 21 is provided with a second card slot 22 engaged with the first card slot 15, the second card slot 22 is engaged with the first card slot 15 of the main baffle 1 to form an anti-unhooking structure and maintain a gap of 3-4mm.

[0029] The anti-slip plate 12 is provided with a plurality of through holes 13 in the array, through which dust and sludge generated by the wire rope can fall, so as not to affect the operation of the wire rope after accumulation; the arc angle of the anti-slip plate 12 is less than 180° (such as Figure 5 The angle indicated by a in the figure is convenient for matching with the rope pulley body.

[0030] The sheave body is configured as a sheave with a slotted groove 3. The second anti-slip hook 21 is integrally formed on both sides of the sheave body, and the second slots 22 on both sides of the sheave body are symmetrically arranged. The main baffle 1 and the sheave with a slotted groove 3 form an anti-slip structure through the first slot 15 and the second slot 22, and the two together constitute a confined space 5 for the wire rope. When the sheave bearing is damaged, the sheave tilts, causing the gap between the main baffle 1 and the wire rope to increase, and the wire rope may slip out of the rope groove and have a tendency to detach from the sheave. When the sheave tilts, the second slot 22 of the sheave body directly hooks into the first slot 15 of the main baffle 1, thereby preventing the wire rope from slipping out. Therefore, the confined space 5 formed by the main baffle 1 and the sheave body can effectively prevent the wire rope from escaping from the sheave.

[0031] Example 2

[0032] The similarities are not repeated here, but the difference from Example 1 is that Figure 7-10 As shown, the rope pulley body is configured as a rope pulley 4 without a slot, and side baffles 2 are fixed on the opposite sides of the rope pulley 4 without a slot, and the second anti-unhooking hook 21 is integrally formed on the edge of the side baffle 2, and the second slot 22 is engaged with the first slot 15 of the main baffle 1 to form an anti-unhooking structure and maintain a gap of 3-4 mm.

[0033] The side baffle 2 is provided with a plurality of screw holes at equal intervals, and the side baffle 2 is fixed to both sides of the rope pulley body by screws, thereby improving the convenience of installing the side baffle 2 and the rope pulley body.

[0034] The side baffle 2 is set to be annular, and a limiting space 5 is formed between the side baffle 2, the rope pulley body and the main baffle 1. Even if the wire rope escapes from the rope groove, it will not escape from the limiting space 5, effectively preventing the wire rope from escaping from the rope pulley, avoiding further damage to the wire rope and the rope pulley.

[0035] The side baffles 2 are directly connected to the sheave, and the main baffle 1 and side baffles 2 form an anti-unhooking structure through the first and second slots 15 and 22. Therefore, the main baffle 1, side baffles 2, and sheave together form a confined space 5 for the wire rope. When the sheave bearing is damaged and the sheave tilts, the gap between the main baffle 1 and the wire rope increases, and the wire rope can slip out of the rope groove and tend to escape from the sheave. When the sheave tilts, the side baffles 2 tilt along with the sheave, and the second slots 22 of the side baffles 2 directly hook into the first slots 15 of the main baffle 1, thereby preventing the wire rope from slipping out. Therefore, the confined space 5 formed by the main baffle 1, side baffles 2, and sheave effectively prevents the wire rope from slipping out of the sheave.
