Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. Based on the embodiments of the invention.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "inner", "outer", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
In the present invention, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "above," and "over" a second feature may mean that the first feature is directly above or obliquely above the second feature, or that only the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.
Referring to fig. 1, a sill 1 is shown, wherein a sliding chute 11 is arranged on the sill 1, and a clamping hole 12 is arranged on a side wall of the sliding chute 11; referring to fig. 2 and 3, there is shown a connection reinforcement assembly 2, said connection reinforcement assembly 2 comprising a mounting base 21 and a vertical rod 22; the mounting seat 21 is fixed on the elevator car door 3, the vertical rod 22 is rotatably arranged on the mounting seat 21, the bottom end of the vertical rod 22 is movably arranged in the sliding groove 11, and a clamping rod 24 protruding in the radial direction is arranged at the bottom end of the vertical rod 22; the upright 22 is connected with an elastic member 23 for providing the upright 22 with a tendency to rotate.
Based on the sill 1 and the connection reinforcing component 2, the invention provides a connection structure of an elevator car door and a sill, the connection reinforcing component 2 is arranged on the elevator car door 3, when the elevator car door 3 is closed, the bottom end of the vertical rod 22 moves in the sliding groove 11, and in the process, as the elastic component 23 provides a rotation trend for the vertical rod 22, the clamping rod 24 can abut against the side wall of the sliding groove 11 to move; after the elevator car door 3 completes the closing action, the bottom end of the vertical rod 22 corresponds to the position of the clamping hole 12, and under the action of the elastic member 23, the vertical rod 22 rotates, and the clamping rod 24 enters the clamping hole 12. Thus, even if the elevator door 3 is impacted, the elevator door is not easily separated from the chute 11 (i.e., the sill groove). In practical applications, the locking hole 12 is a slot hole with a certain length in the horizontal direction, so that the locking rod 24 has enough space to enter the locking hole 12; referring to fig. 4, when the elevator doors 3 are closed and the two elevator doors 3 approach each other to a certain distance L, the locking rod 24 will encounter the locking hole 12, and under the action of the elastic member 23, the locking rod 24 will rotate into the locking hole 12 as the closing of the elevator doors 3 proceeds. When the elevator door 3 is opened, the lock lever 24 is stopped by the edge of the lock hole 12 when moving along with the elevator door 3, and the elastic member 23 is pressed as the opening of the elevator door 3 progresses, so that the lock lever 24 is separated from the lock hole 12 and returns to the slide groove 11. The elastic member 23 may be a Torsion Spring (Torsion Spring). It should be noted that, when the vertical rod 22 and the clamping rod 24 move in the sliding slot 11, the clamping rod 24 is closer to the corresponding entering clamping hole 12 than the vertical rod 22. When the locking rod 24 does not correspond to the locking hole 12 in the sliding slot 11, it cannot be perpendicular to the side wall of the sliding slot 11, that is, the length of the locking rod 24 should be greater than the width of the sliding slot 11.
In some embodiments, in order to avoid that the clamping rod 24 will scrape the side wall of the sliding slot 11, or will wear the clamping rod 24 itself, or will affect the smoothness of the movement of the vertical rod 22 in the sliding slot 11 under the action of the elastic member 23; referring to fig. 2 and 3, the catch lever 24 is provided with a guide wheel 25 rotating along a vertical axis, and under the action of the elastic member 23 on the vertical rod 22, the guide wheel 25 abuts against the side wall of the chute 11. In this way, referring to fig. 4 and 5, the guide wheel 25 is used to replace the clamping rod 24 abutting against the side wall of the sliding chute 11, so that on one hand, the clamping rod 24 and the side wall of the sliding chute 11 can be prevented from being worn, on the other hand, the smoothness of movement of the vertical rod 22 in the sliding chute 11 can be ensured, and the elevator car door 3 can be prevented from being unsmooth in the opening or closing process. When the locking rod 24 does not correspond to the locking hole 12 in the sliding slot, it cannot be perpendicular to the side wall of the sliding slot 11, i.e. the total length of the locking rod 24 and the guide wheel 25 after combination should be greater than the width of the sliding slot 11.
In some embodiments, when the horizontal length of the latch hole 12 is set to be too long, the latch lever 24 may be excessively rotated by the elastic member 23 to be disengaged from the latch hole 12. Referring to fig. 2 and 3, the vertical rod 22 is provided with a limiting member, and the limiting member limits the maximum angle at which the elastic member 23 drives the vertical rod 22 to rotate. In other words, the jamming rod 24 is prevented from rotating into the jamming hole 12 first and then continuing to rotate out of the jamming hole 12 under the action of the elastic member 23. Specifically, referring to fig. 6 and 7, the limiting member is a limiting block 26 fixed on the outer peripheral side of the vertical rod 22, and when the elastic member 23 drives the vertical rod 22 to rotate to the maximum angle, the limiting block 26 abuts against the mounting seat 21. In order to ensure that the elevator car door 3 and the sill 1 are connected stably as much as possible, when the elastic member 23 drives the vertical rod 22 to rotate to the maximum angle, the clamping rod 24 is perpendicular to the side wall of the sliding groove 11; in this way, when the elevator door 3 is impacted, the catch rod 24 is more difficult to be disengaged from the catch hole 12.
In some specific embodiments, in order to reduce the requirement for the installation accuracy of the installation seat 21, referring to fig. 2 and 3, the vertical rod 22 is arranged on the installation seat 21 in a liftable manner. Optionally, the mounting seat 21 includes a horizontal plate 211 horizontally disposed, the vertical rod 22 is rotatably and vertically disposed on the horizontal plate 211, a plurality of nuts 27 are threadedly connected to the vertical rod 22, the nuts 27 are respectively located above and below the horizontal plate 211, and the vertical rod 22 is adjusted in height on the mounting seat 21 by adjusting positions of the nuts 27 on the vertical rod 22. The structure is simple and the manufacturing cost is low. In this way, the height of the vertical rod 22 is adjustable, so that the situation that the clamping rod 24 cannot enter the clamping hole 12 due to inaccurate installation height of the installation seat 21 can be avoided.
Referring to fig. 1, 5 and 7, two sidewalls of the chute 11 are defined as a first sidewall 111 and a second sidewall 112, and the card hole 12 includes a first card hole 121 disposed on the first sidewall 111 and a second card hole 122 disposed on the second sidewall 112. Defining the closed surfaces of the two elevator car doors 3 after being closed on the sill 1 as an interface 4; wherein, two elevator car doors 3 can be respectively provided with a connection reinforcing component 2, and two sides of the interface on the sill are respectively provided with a clamping hole 12 corresponding to the connection reinforcing component 2; however, since the sill 1 has a considerable length, in order to further improve the connection stability between the sill 1 and the elevator car door 3, it is preferable that the sill 1 is provided with two first locking holes 121 and two second locking holes 122, the two first locking holes 121 are symmetrically arranged with the interface 4 as a reference, and the two second locking holes 122 are symmetrically arranged with the interface 4 as a reference. Two of the second card holes 122 are closer to the interface 4, and two of the first card holes 121 are further from the interface 4. In other words, the sill 1 is provided with four clamping holes 12, and one elevator car door 3 is provided with two connection reinforcing components 2, so that the connection stability of the elevator car door 3 and the sill 1 is enhanced; in addition, in order to ensure that the elevator car door 3 can smoothly complete the opening and closing actions, two connection reinforcing components 2 on one elevator car door 3 respectively correspond to one first clamping hole 121 and one second clamping hole 122, so that when the elevator car door 3 is opened and closed, only one clamping hole 12 can be met in the moving process of the guide wheel 25 of the connection reinforcing component 2 in the sliding groove 11.
Based on the connecting mechanism of the elevator car door 3 and the sill 1, the elevator passing through mark transformation method is provided, and comprises the following steps without restriction of sequence:
s1: replacing the original sill of the old elevator with any one of the sills 1;
s2: any one of the connection reinforcing components 2 is installed on the original elevator car door of the old elevator.
In step S1, after the original sill of the old elevator is removed, the locking hole 12 is processed on the original sill, and after the original sill is modified into any one of the above sills 1, the elevator is installed back to the original position; or the clamping hole 12 is processed on the sill with the same specification as the original sill of the old elevator, and the original sill of the old elevator is replaced after the sill 1 is transformed into any one of the above. Referring to fig. 1, when the first locking hole 121 is machined, the first sidewall 111 may be drilled through from one side of the sill 1; when the second locking hole 122 is machined, the first sidewall 111 and the second sidewall 112 may be drilled from one side of the doorsill 1.
In step S2, after the original elevator car door of the old elevator is removed, any one of the connection reinforcing assemblies 2 can be installed on the original elevator car door, and then the installation is returned to the original position; or any one of the connection reinforcing components 2 is installed on the elevator car door with the same specification as the original elevator car door of the old elevator, and then the original elevator car door of the old elevator is replaced. The mounting seat 21 of the connection reinforcing component 2 can be mounted on the elevator car door 3 by welding or bolt fixing.
The conventional elevator is modified by the elevator through mark modification method, only a plurality of clamping holes 12 need to be processed on the sill 1, and the connection reinforcing component 2 is installed on the elevator car door 3, so that other parts of the conventional elevator are not affected, and other parts do not need to be matched; the treatment difficulty is low and the transformation cost can be effectively reduced.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
