Description
Technical Field
[0001] The present invention relates to the technical field of elevators, and in particular to a connection structure between an elevator car door and a sill and an elevator standard-compliant modification method. Background Art
[0002] Many elevator renovations retain the original parts of the old elevators. For safety reasons, customers or relevant regional agencies will require compliance with the standards for parts of the old elevators that do not meet the national standards. When the elevator is renovated and the car frame is retained, the original car door sill groove is too shallow, and the car door is easy to slip out of the sill groove when impacted, and the car door strength does not meet the new national standards. At this stage, the main way to achieve the car door strength compliance is to increase the depth of the sill groove and add pallets to meet the new national standards. Due to the structural limitations of the old elevator, if the sill of the deep sill groove is replaced, it is required to replace the car bottom or match other related parts of the old elevator, which is difficult to handle and costly. Summary of the invention
[0003] In view of this, the present invention proposes, on the one hand, a connection structure between an elevator car door and a sill, which can solve the problem that the car door easily slips out of the sill groove; on the other hand, it proposes an elevator standardization retrofit method, which can solve the problem that it is difficult and costly to carry out standardization retrofit on old elevators.
[0004] The technical solution of one aspect of the present invention is achieved as follows:
[0005] A connection structure between an elevator car door and a sill, comprising:
[0006] A sill, wherein a slide groove is provided on the sill, and a clamping hole is provided on the side wall of the slide groove;
[0007] A connection reinforcement component, the connection reinforcement component comprises a mounting seat and a vertical rod; the mounting seat is fixed on the elevator car door, the vertical rod is rotatably arranged on the mounting seat, the bottom end of the vertical rod is movably placed in the slide groove, and the bottom end of the vertical rod is provided with a radially protruding clamping rod; the vertical rod is connected to an elastic member for providing a rotation tendency for the vertical rod;
[0008] When the vertical rod moves along the sliding groove to a position corresponding to the clamping hole, the elastic component causes the vertical rod to rotate so that the clamping rod enters the clamping hole.
[0009] As a further optional solution for the connection structure between the elevator car door and the sill, a guide wheel rotating along a vertical axis is provided on the clamping rod, and under the action of the elastic component on the vertical rod, the guide wheel abuts against the side wall of the sliding groove.
[0010] As a further optional solution for the connection structure between the elevator car door and the sill, a limiting member is provided on the vertical rod, and the limiting member limits the maximum angle of rotation of the vertical rod driven by the elastic member.
[0011] As a further optional scheme for the connection structure between the elevator car door and the sill, the limiting member is a limiting block fixed on the outer peripheral side of the vertical rod, and when the elastic member drives the vertical rod to rotate to the maximum angle, the limiting block abuts against the mounting seat, and the clamping rod is perpendicular to the side wall of the slide groove.
[0012] As a further optional solution for the connection structure between the elevator car door and the sill, the vertical rod is liftably arranged on the mounting seat.
[0013] As a further optional scheme for the connection structure between the elevator car door and the sill, the two side walls of the slide groove are defined as a first side wall and a second side wall, and the clamping hole includes a first clamping hole arranged on the first side wall and a second clamping hole arranged on the second side wall.
[0014] As a further optional scheme for the connection structure between the elevator car door and the sill, the closing surface after the two elevator car doors are closed on the sill is defined as a dividing interface, and two first clamping holes and two second clamping holes are provided on the sill, and the two first clamping holes are symmetrically arranged with respect to the dividing interface as a reference, and the two second clamping holes are symmetrically arranged with respect to the dividing interface as a reference.
[0015] The connection structure utilizes a connection reinforcement component to reinforce the connection between the sill and the elevator car door, which can effectively improve the connection stability between the sill and the elevator car door and prevent the elevator car door from easily falling off the sill when impacted; the connection structure is convenient for modifying the original elevator, and only requires processing a number of card holes on the sill and installing the connection reinforcement component on the elevator car door, without any impact on other components of the original elevator, and no matching processing is required for other components.
[0016] The technical solution of another aspect of the present invention is achieved as follows:
[0017] An elevator standardization transformation method includes the following steps in an unrestricted order:
[0018] S1: Replace the original sill of the old elevator with any of the above sills;
[0019] S2: Install any of the above connection reinforcement components on the original elevator car door of the old elevator.
[0020] Among them, in step S1, the original sill of the old elevator can be dismantled, and a clamping hole can be processed on the original sill, and it can be transformed into any of the above-mentioned sills before being installed back to its original position; or a clamping hole can be processed on a sill of the same specification as the original sill of the old elevator, and it can be transformed into any of the above-mentioned sills before replacing the original sill of the old elevator.
[0021] Among them, in step S2, the original elevator car door of the old elevator can be removed, and any one of the above-mentioned connection reinforcement components can be installed on the original elevator car door, and then installed back to its original position; or any one of the above-mentioned connection reinforcement components can be installed on an elevator car door of the same specification as the original elevator car door of the old elevator, and then the original elevator car door of the old elevator can be replaced.
[0022] To modify the original elevator using this elevator standard-compliant modification method, it is only necessary to process a number of holes on the sill and install the connection reinforcement components on the elevator door. This will not affect other components of the original elevator and does not require matching processing on other components. The processing difficulty is low and the modification cost can be effectively reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention.
[0033] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0034] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0035] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0036] refer to Figure 1 , showing a sill 1, the sill 1 is provided with a slide groove 11, and the side wall of the slide groove 11 is provided with a clamping hole 12; Figure 2 and Figure 3, shows a connection reinforcement component 2, the connection reinforcement component 2 includes a mounting seat 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 placed in the slide groove 11, and the bottom end of the vertical rod 22 is provided with a radially protruding clamping rod 24; the vertical rod 22 is connected to an elastic member 23 for providing a rotation tendency for the vertical rod 22.
[0037] Based on the above sill 1 and connection reinforcement component 2, the present invention proposes a connection structure between an elevator car door and a sill, wherein the connection reinforcement component 2 is installed 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 slide groove 11. During this process, since the elastic component 23 provides a rotation tendency for the vertical rod 22, the clamping rod 24 will move against the side wall of the slide groove 11; and when 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. Under the action of the elastic component 23, the vertical rod 22 rotates, and the clamping rod 24 enters the clamping hole 12. In this way, even if the elevator car door 3 is impacted, it is not easy to escape from the slide groove 11 (i.e., the sill groove). In actual applications, the clamping hole 12 is a slot having a certain length in the horizontal direction, so that the clamping rod 24 has enough space to enter the clamping hole 12; refer to Figure 4 When the elevator car door 3 is closed, when the two elevator car doors 3 are close to each other to a certain distance L, the clamping rod 24 will encounter the clamping hole 12. Under the action of the elastic member 23, as the elevator car door 3 is closed, the clamping rod 24 rotates into the clamping hole 12. In addition, when the elevator car door 3 is opened, the clamping rod 24 is blocked by the edge of the clamping hole 12 when it moves with the elevator car door 3. As the elevator car door 3 is opened, the elastic member 23 is suppressed, and the clamping rod 24 is separated from the clamping hole 12 and returns to the chute 11. The elastic member 23 can be a torsion spring. It should be noted that when the vertical rod 22 and the clamping rod 24 move in the chute 11, the clamping rod 24 is closer to the corresponding clamping hole 12 than the vertical rod 22. When the latching rod 24 does not correspond to the latching hole 12 in the slide slot 11 , it cannot be perpendicular to the side wall of the slide slot 11 , that is, the length of the latching rod 24 should be greater than the width of the slide slot 11 .
[0038] In some specific embodiments, in order to prevent the clamping rod 24 from scratching the side wall of the slide groove 11 under the action of the elastic member 23, or causing wear to the clamping rod 24 itself, or affecting the smoothness of the vertical rod 22 moving in the slide groove 11; Figure 2 and Figure 3The clamping rod 24 is provided with a guide wheel 25 rotating along a vertical axis. Under the action of the elastic member 23 on the vertical rod 22, the guide wheel 25 abuts against the side wall of the slide groove 11. Figure 4 and Figure 5 , using the guide wheel 25 instead of the clamping rod 24 to abut against the side wall of the chute 11, on the one hand, it can prevent the clamping rod 24 and the side wall of the chute 11 from being worn, and on the other hand, it can ensure the smooth movement of the vertical rod 22 in the chute 11, and avoid the elevator car door 3 from being unsmooth during the opening or closing process. Among them, when the clamping rod 24 does not correspond to the clamping hole 12 in the chute, it cannot be perpendicular to the side wall of the chute 11, that is, the total length of the clamping rod 24 and the guide wheel 25 after combination should be greater than the width of the chute 11.
[0039] In some specific embodiments, when the horizontal length of the clamping hole 12 is set too long, the clamping rod 24 may rotate excessively under the action of the elastic member 23 and disengage from the clamping hole 12. Figure 2 and Figure 3 The vertical rod 22 is provided with a limit member, and the limit member limits the maximum angle of rotation of the vertical rod 22 driven by the elastic member 23. In other words, it is prevented that the clamping rod 24, under the action of the elastic member 23, first rotates into the clamping hole 12 and then continues to rotate out of the clamping hole 12. Specifically, refer to Figure 6 and Figure 7 The limiting member is a limiting block 26 fixed on the outer peripheral side of the vertical rod 22. 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 make the elevator door 3 and the sill 1 connected as firmly 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 slide groove 11; in this way, when the elevator door 3 is impacted, the clamping rod 24 is more difficult to escape from the clamping hole 12.
[0040] In some specific implementations, in order to reduce the requirements on the installation accuracy of the mounting seat 21, refer to Figure 2 and Figure 3, the vertical rod 22 can be raised and lowered on the mounting seat 21. Optionally, the mounting seat 21 includes a horizontally arranged transverse plate 211, the vertical rod 22 can be rotatably and vertically arranged on the transverse plate 211, and a plurality of nuts 27 are threadedly connected to the vertical rod 22, and the nuts 27 are respectively located above and below the transverse plate 211. By adjusting the positions of the nuts 27 on the vertical rod 22, the height of the vertical rod 22 on the mounting seat 21 can be adjusted. The structure is simple and the manufacturing cost is low. In this way, the height of the vertical rod 22 is adjustable, which can avoid the situation where the clamping rod 24 cannot enter the clamping hole 12 due to the inaccurate installation height of the mounting seat 21.
[0041] refer to Figure 1 , Figure 5 and Figure 7 The two side walls of the slide groove 11 are defined as a first side wall 111 and a second side wall 112, and the clamping hole 12 includes a first clamping hole 121 provided on the first side wall 111 and a second clamping hole 122 provided on the second side wall 112. The closed surface of the two elevator car doors 3 after closing on the sill 1 is defined as a boundary surface 4; wherein, a connection reinforcement component 2 can be provided on each of the two elevator car doors 3, and a clamping hole 12 corresponding to the connection reinforcement component 2 is provided on each of the two sides of the boundary surface on the sill; but 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, preferably, the sill 1 is provided with two first clamping holes 121 and two second clamping holes 122, the two first clamping holes 121 are symmetrically arranged with the boundary surface 4 as a reference, and the two second clamping holes 122 are symmetrically arranged with the boundary surface 4 as a reference. The two second clamping holes 122 are closer to the boundary surface 4, and the two first clamping holes 121 are farther away from the boundary surface 4. In other words, four latching holes 12 are provided on the sill 1, and two connection reinforcement components 2 are provided on one elevator car door 3, thereby strengthening the connection stability between the elevator car door 3 and the sill 1; in addition, to ensure that the elevator car door 3 can smoothly complete the opening and closing action, the two connection reinforcement components 2 on one elevator car door 3 should correspond to a first latching hole 121 and a second latching hole 122 respectively, so that when the elevator car door 3 opens and closes, the guide wheel 25 of the connection reinforcement component 2 will only encounter one latching hole 12 during the movement in the slide groove 11.
[0042] Based on the above-mentioned connection mechanism between the elevator car door 3 and the sill 1, a method for elevator standardization transformation is provided, which includes the following steps in an unrestricted order:
[0043] S1: Replace the original sill of the old elevator with any of the above sills 1;
[0044] S2: Install any one of the above-mentioned connection reinforcement components 2 on the original elevator car door of the old elevator.
[0045] In step S1, the original sill of the old elevator can be dismantled, and a clamping hole 12 can be processed on the original sill to transform it into any of the above sills 1, and then installed back to the original position; or a clamping hole 12 can be processed on a sill of the same specification as the original sill of the old elevator, and then transformed into any of the above sills 1 to replace the original sill of the old elevator. Figure 1 When processing the first clamping hole 121, the first side wall 111 can be drilled from one side of the sill 1; and when processing the second clamping hole 122, the first side wall 111 and then the second side wall 112 can be drilled from one side of the sill 1.
[0046] In step S2, the original elevator car door of the old elevator can be removed, and any one of the above-mentioned connection reinforcement components 2 can be installed on the original elevator car door, and then installed back to the original position; or any one of the above-mentioned connection reinforcement components 2 can be installed on the elevator car door of the same specification as the original elevator car door of the old elevator, and then replace the original elevator car door of the old elevator. The mounting seat 21 of the connection reinforcement component 2 can be installed on the elevator car door 3 by welding or bolting.
[0047] By utilizing the elevator standard-compliant renovation method to renovate the original elevator, it is only necessary to process a plurality of card holes 12 on the sill 1 and install the connection reinforcement assembly 2 on the elevator car door 3. This will not have any impact on other components of the original elevator and there is no need to match other components. The processing difficulty is low and the renovation cost can be effectively reduced.
[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
