Detailed Description

The following specific embodiments are merely illustrative of the present invention, and are not intended to limit the present invention, and those skilled in the art can make modifications of the present embodiments without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent laws and protection within the scope of the present invention.

The shoe liner 1 shown in fig. 1 includes a first wear-resistant layer 11 and a second wear-resistant layer 12, the second wear-resistant layer 12 is attached to the outer side of the first wear-resistant layer 11, a sliding groove 13 for direct contact of a guide rail is formed on the inner side of the first wear-resistant layer 11, and a first through hole 121 is formed in the second wear-resistant layer 12. In actual use, the guide rail of the elevator passes through the sliding groove 13 of the shoe liner 1 and directly contacts the sliding groove 13, i.e., the guide rail directly contacts the inner side of the first wear-resistant layer 11, and the shoe liner 1 slides up and down along the guide rail in the daily use of the elevator, during which the guide rail repeatedly rubs against the inner side of the first wear-resistant layer 11, thereby causing abrasion to the first wear-resistant layer 11. The wear of the first wear layer 11 is proceeding from its inner side towards the outer side and accumulates until the first wear layer 11 is completely worn away, at which point the guide rail is in direct contact with the inner side of the second wear layer 12. The thickness of the first wear layer 11, i.e. the maximum thickness of the lining 1 that can be worn, is preferably chosen in this embodiment, i.e. the thickness of the first wear layer 11 that can be worn until it disappears, and the lining 1 needs to be replaced, while the maximum thickness of the lining 1 that can be worn depends on the specific requirements, and the thickness of the second wear layer is preferably approximately half of the thickness of the first wear layer. In this embodiment, the second wear-resistant layer 12 is provided with a first through hole 121, the first through hole penetrates through the second wear-resistant layer 12 and communicates with the outside of the first wear-resistant layer 11, after the first wear-resistant layer 11 disappears, the guide rail directly contacts with the inner side of the second wear-resistant layer 12, and the first through hole 121 is no longer plugged by the outside of the first wear-resistant layer 11, at this time, the oil dirt on the guide rail overflows to the outside of the second wear-resistant layer 12 from the first through hole 121, namely, the outside of the shoe liner 1, the maintenance personnel observe the oil dirt on the outside of the shoe liner 1, and can know that the first wear-resistant layer 11 disappears due to abrasion, so as to judge that the shoe liner 1 needs to be replaced with a new one, and the shoe liner is convenient and fast. Meanwhile, the wear condition prompting mode is realized by only opening the first through hole 121 on the second wear-resistant layer 12 in the shoe liner 1 without other parts arranged on the shoe liner 1, so that the production cost is hardly increased under the condition of normal production of the shoe liner 1; and the guide rail is always contacted with the shoe guide 1 body, and other parts are not involved, so that the smooth sliding of the shoe guide 1 along the guide rail is ensured, and the riding comfort is ensured.

In this embodiment, the thickness of first wearing layer 11 is even, the guide rail is also everywhere even to the wearing and tearing of first wearing layer 11, make each department wearing and tearing progress of first wearing layer 11 unanimous substantially, so then can set up first through-hole 121 at a plurality of positions on second wearing layer 12, make the grease on the guide rail spill over from a plurality of first through-holes 121, the contingency of jam appears when avoiding only having single first through-hole 121, ensure that the condition of spilling over of grease can be in time found by the maintenance personnel, guarantee that shoe lining 1 is in time changed, thereby guarantee to take advantage of the safe and comfortable of ladder. Because first wearing layer 11 and second wearing layer 12 are polymer wear-resistant material, so the preferred both materials of this embodiment are the same, add man-hour with both integrated into one piece processing, need not to splice after separately processing both, both accelerated machining efficiency, reduced the processing cost, make first wearing layer 11 and second wearing layer 12's wholeness obtain showing the improvement again, the self intensity of the shoe guide 1 that both constitute obtains effectively guaranteeing. After the first wear-resistant layer 11 and the second wear-resistant layer 12 are integrally formed, they form a whole, and at this time, the first through hole 121 becomes a blind hole relative to the whole.

The shoe lining 1 in this embodiment is substantially u-shaped, the inner side is the sliding groove 13, and at this time, the sliding groove 13 is surrounded by the whole body formed by the first wear-resistant layer 11 and the second wear-resistant layer 12 from three directions, in this embodiment, preferably, a plurality of first through holes 121 are formed in the second wear-resistant layer 12, and at least three first through holes 121 are communicated to the first wear-resistant layer 11 from the outer side of the second wear-resistant layer 12 along different directions, so that the shoe lining has the advantage that after the wear of the first wear-resistant layer 11 disappears, the grease can flow out to the outer side of the second wear-resistant layer 12 from three different directions, so that a maintenance worker can observe the flow of the grease from multiple positions, and can ensure that the flow of the grease is found in time, thereby ensuring that the shoe lining 1 is replaced in time. The first through hole 121 only needs to penetrate through the second wear-resistant layer 12 and enable the grease to smoothly flow out of the second wear-resistant layer 12, the shape of the first through hole has no special requirement, and different shapes can be selected according to specific situations. In addition, since the grease is viscous, the flow speed thereof is slow, and the grease may overflow from the first through hole 121 after a long time has elapsed after the first wear-resistant layer 11 disappears, so that the liner 1 cannot be replaced even though it is, resulting in poor safety and comfort of riding the elevator for a while. Therefore, the further improvement is that the first through hole 121 on the second wear-resistant layer 12 is set to be inclined, and the inclined state is that the end close to the outer side is lower than the end close to the inner side, so that the oil dirt entering the first through hole 121 from the inner side of the second wear-resistant layer 12 can flow towards the outer side of the second wear-resistant layer 12 under the action of gravity, the flowing speed of the oil dirt is improved, the time interval between the disappearance of the first wear-resistant layer 11 and the appearance of the oil dirt on the outer side of the second wear-resistant layer 12 is shortened, and the shoe lining 1 is ensured to be replaced in time. In this embodiment, the first wear-resistant layer 11 and the second wear-resistant layer 12 are both made of high molecular wear-resistant materials, such as nylon.

In actual use, the shoe guide 1 needs to be installed in a shoe support, fig. 6 shows a shoe guide assembly 3, which includes the shoe guide 1, and further includes a shoe support 2 for installing the shoe guide 1, the shoe support 2 has an installation groove 21 for installing the shoe guide 1, and the shoe support 2 is provided with a second through hole 22 correspondingly communicated with the first through hole 121. After the boot liner 1 is installed in the installation groove 21 of the boot support 2, as long as the first through hole 121 on the second wear layer 12 in the boot liner 1 is shielded by the boot support 2, the position on the boot support 2 corresponding to the first through hole 121 needs to be provided with the second through hole 22 so that grease can flow to the outside of the boot support 2. When the first wear layer 11 on the liner 1 is worn and disappeared, the grease flows from the first through hole 121 to the second through hole 22, and then flows to the outside of the boot supporter 2 through the second through hole 22, and preferably, the diameter of the second through hole 22 is slightly larger than that of the first through hole 121, so that the grease can flow out. Since the liner 1 in the above described embodiment is substantially u-shaped, the boot support 2 is also substantially u-shaped to be wrapped from three sides around the outside of the second wear layer 12. in this embodiment the boot support 2 is preferably a galvanized iron part, which is wrapped with a layer of rubber.

In actual use, the guide shoe assembly needs to be installed in the guide shoe body, fig. 7 shows an elevator guide shoe, which comprises the guide shoe assembly 3 and the guide shoe body 4, wherein the guide shoe assembly 3 is inserted into the accommodating groove 43 of the guide shoe body 4 in the vertical direction for installation, the guide shoe assembly 3 can only move in the vertical direction in the accommodating groove 43, and other movement directions are sufficiently limited. And the guide shoe body 4 is provided with a guide shoe head 41 positioned above and a guide shoe seat 42 positioned below, the guide shoe head 41 is used for installing an oil supply cup and pressing the guide shoe assembly 3 from the upper part, and the guide shoe seat 42 is used for fixedly connecting with the elevator car and carrying the guide shoe assembly 3 from the lower part, so that the guide shoe assembly 3 is limited in the accommodating groove 43. In this embodiment, after the boot assembly 3 is installed in the accommodating groove 43 of the boot guiding body 4, the second through hole 22 of the boot bracket 2 is not blocked by the boot guiding body 4, so that the maintenance personnel can observe the outflow of the grease.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope of the present invention, and these modifications or replacements should be covered within the scope of the present invention.
