Description

Technical Field

[0001] This application relates to the field of elevator technology, and in particular to a drip plate docking structure and an elevator. Background Technology

[0002] In the existing elevator installation process, the original drip plates are mostly installed on-site by inserting male and female connectors. Specifically, the drip plates have barbed mounting grooves at both ends and mounting heads that match the shape of the mounting grooves. During construction, the drip plates need to be bent on-site to reduce their original size so that the mounting grooves can cover and fit tightly against the mounting heads, thereby connecting and fixing two adjacent drip plates.

[0003] For wellbore systems using a two-section hoisting method, this drip plate structure has a significant drawback. Specifically, at the joint between the two wellbore sections, the drip plate uses a male-female insertion method (see attached image). Figure 5 As shown, the allowable error for the fit between the mounting head and the mounting groove is very small. Therefore, the two-section hoisting system cannot achieve simultaneous hoisting of the hoistway and the facade. Instead, the drip edge assembly and installation must be carried out separately using an aerial work platform after the hoisting of both sections is completed. This not only increases the operating costs of construction equipment, such as the daily operating costs of cranes and aerial work platforms, but also consumes a significant amount of labor for on-site facade installation. Furthermore, working at height poses certain safety risks, affecting the overall efficiency and safety of the construction. Additionally, because the drip edge uses a male-female interlocking design, it needs to be bent on-site to reduce its original size in order to tightly engage the mounting groove and the mounting head. This can easily lead to deformation of the drip edge, thus affecting the quality of the hoistway facade. Utility Model Content

[0004] Therefore, it is necessary to provide a drip plate docking structure and elevator to solve the problems that the drip plate and the two-end shaft cannot be hoisted synchronously and that the deformation of the drip plate affects the quality and waterproof performance of the shaft facade.

[0005] A drip plate docking structure is used to be installed on the outer side of the docking point of two well sections. The drip plate docking structure includes an upper plate and a lower plate. The upper plate is used to connect the upper end of the docking point, and the lower plate is used to connect the lower end of the docking point. One end of the upper plate has a groove structure, and one end of the lower plate has a plug-in part. At least a portion of the plug-in part can be inserted into the groove structure when the upper end and the lower end approach each other, and the plug-in part inserted into the groove structure forms a point contact or line contact abutment with the inner wall of the groove structure.

[0006] In one of the embodiments, the plug-in part is configured as a bent piece, one end of which extends out of the groove structure and is used to abut against the outer side of the lower end head, and the other end of which is suspended; and in the process of the upper end head and the lower end head approaching each other, the bent piece can be elastically deformed in response to the extrusion of the inner wall of the groove structure, and the end of the bent piece that is suspended is tightly abutted against the inner wall of the groove structure.

[0008] In one of the embodiments, the bent piece has a plurality of first bent parts, which are respectively abutted against the inner wall of the groove structure or the outer side of the lower end head. 。

[0009] In one of the embodiments, the inner wall of the groove structure includes a bottom wall opposite to the opening end of the groove structure, and a first inner wall and a second inner wall respectively located on both sides of the bottom wall, the second inner wall is located close to the side of the upper end head relative to the first inner wall; the bent piece has at least three first bent parts, which are respectively abutted against the inner wall of the groove structure and the outer side of the lower end head to form at least three abutment points, and the first and last abutment points form a polygonal support structure.

[0010] In one of the embodiments, the part of the bent piece located inside the groove structure is defined as a first part, and the cross-sectional area of the first part is smaller than the cross-sectional area of the groove structure.

[0011] In one of the embodiments, the upper plate includes a first plate and a second plate, one end of the second plate has an opening, and the first plate is inserted into the opening from the side of the second plate to form the groove structure together with the second plate.

[0012] In one of the embodiments, the first plate and the second plate are respectively used to connect to different sides of the second keel of the upper end head.

[0013] In one of the embodiments, the first plate includes a third bent part and a fourth bent part, the third bent part is used to connect the outer side, the lower side and at least part of the inner side of the second keel, and the fourth bent part is attached to the opening, and at least part of the opening extends out of the fourth bent part and is used to connect the upper side of the second keel.

[0014] In one of the embodiments, the upper plate has at least one first rain-shielding protrusion, and the lower plate has at least one second rain-shielding protrusion.

[0015] In one of the embodiments, along the direction from the upper plate to the lower plate, the cross-sectional width of the groove structure tends to increase.

[0016] In one of the embodiments, the upper plate is provided with a first connecting position at the end away from the lower plate, and the lower plate is provided with a second connecting position at the end away from the upper plate, and the first connecting position and the second connecting position are respectively used for plug-in cooperation with the drip plate of the outer facade of the adjacent hoistway.

[0018] The drip plate butt joint structure provided by the application has a large allowable error during the plug-in cooperation of the plug-in part and the groove structure, so that the plug-in cooperation of the plug-in part and the groove structure can be completed synchronously during the hoisting of the two hoistways after the upper plate is connected to the upper end and the lower plate is connected to the lower end. In this way, the work of climbing the vehicle and the on-site installation of the drip plate butt joint structure can be avoided. In addition, the plug-in cooperation between the upper plate and the lower plate in the application is only through the plug-in part and the groove structure, and the upper plate or the lower plate does not need to be bent or reduced in size on site, so as to facilitate the guarantee of the quality of the outer facade.

The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used in the specification of the present application includes any and all combinations of one or more related listed items.

[0031] Please refer to Figures 1 to 3 The present application provides a drip plate butt joint structure 10 for mounting to the outer side of the butt joint of two shafts 200, the drip plate butt joint structure 10 comprising an upper plate 110 and a lower plate 120, the upper plate 110 being used to connect the upper end head 210 of the butt joint, the lower plate 120 being used to connect the lower end head 220 of the butt joint, one end of the upper plate 110 having a groove structure 111, and one end of the lower plate 120 having a plug-in part 121. At least part of the plug-in part 121 can be inserted into the groove structure 111 during the mutual approach of the upper end head 210 and the lower end head 220, and the plug-in part 121 inserted into the groove structure 111 forms a point or line contact with the inner wall of the groove structure 111.

[0032] It should be noted that when the upper plate 110 is connected to the upper end head 210, the opening end of the groove structure 111 is arranged towards the lower plate 120 below. In addition, it should be noted that the plug-in part 121 inserted into the groove structure 111 forms a point contact or line contact with the inner wall of the groove structure 111, which means that the part of the surface of the plug-in part 121 located in the groove structure 111 forms a point contact or line contact with the inner wall of the groove structure 111, and the other surfaces of the plug-in part 121 located in the groove structure 111 are arranged to be spaced from the inner wall of the groove structure 111, so that the plug-in part 121 has a large assembly error with the groove structure 111. Therefore, compared with the related structure in which the mounting groove is wrapped around and tightly fitted with the mounting head, the water dripping plate butt joint structure 10 provided by the application has a large allowable error during the butt joint installation of the plug-in part 121 and the groove structure 111, so that the butt joint of the plug-in part 121 and the groove structure 111 can be completed synchronously during the hoisting process of the two shafts 200 after the upper plate 110 is connected to the upper end head 210 and the lower plate 120 is connected to the lower end head 220. Therefore, it can be avoided to climb the vehicle and install the water dripping plate butt joint structure on site. In addition, in the application, the upper plate 110 and the lower plate 120 are only plugged and matched by the plug-in part 121 and the groove structure 111, and there is no need to fold and reduce the size of the upper plate 110 or the lower plate 120 on site, so as to facilitate the guarantee of the quality of the outer surface.

[0033] In one embodiment, the plug-in part 121 is configured as a bent piece 121a, one end of the bent piece 121a extends out of the groove structure 111 and is used for abutting to the outside of the lower end head 220, and the other end of the bent piece 121a is arranged to be suspended; and during the process that the upper end head 210 and the lower end head 220 approach each other, the bent piece 121a can be elastically deformed in response to the extrusion of the inner wall of the groove structure 111, and the end of the bent piece 121a suspended can be tightly abutted to the inner wall of the groove structure 111. Therefore, the end of the bent piece 121a suspended can be tightly abutted to the inner wall of the groove structure 111 under the action of the elastic force, so as to guarantee the waterproof performance of the plug-in part 121 and the groove structure 111.

[0034] Optionally, the lower plate 120 further comprises a connecting part 122, and the end of the bent piece 121a extending out of the groove structure 111 is connected to the first keel 221 on the lower end head 220 through the connecting part 122.

[0035] In the application, the inner wall of the groove structure 111 comprises a bottom wall 101 opposite to the opening end of the groove structure 111, and a first inner wall 102 and a second inner wall 103 respectively arranged on both sides of the bottom wall 101, and the second inner wall 103 is arranged on the side close to the upper end head 210 relative to the first inner wall 102.

[0036] In an embodiment, the bending piece 121a has a plurality of first bending portions 121d, which respectively form abutting fit with the inner wall or the lower end head 220 of the groove structure 111. Specifically, the plurality of first bending portions 121d form abutting fit with the first inner wall 102 and the lower end head 220; or, the plurality of first bending portions 121d form abutting fit with the first inner wall 102, the second inner wall 103 and the lower end head 220; or, the plurality of first bending portions 121d form abutting fit with the bottom wall 101 and the lower end head 220; or, the plurality of first bending portions 121d form abutting fit with the first inner wall 102, the bottom wall 101 and the lower end head 220; or, the plurality of first bending portions 121d form abutting fit with the bottom wall 101, the second inner wall 103 and the lower end head 220; or, the plurality of first bending portions 121d form abutting fit with the first inner wall 102, the bottom wall 101, the second inner wall and the lower end head 220. It should be noted that the first bending portion 121d refers to the corner position of the bending piece 121a or the end point of the bending piece 121a. By arranging the plurality of first bending portions 121d to respectively form abutting fit with the inner wall or the lower end head 220 of the groove structure 111, the firmness of the plug-in fit between the bending piece 121a and the groove structure 111 can be improved.

[0037] Optionally, in an embodiment, the bending piece 121a has at least three first bending portions 121d, which respectively form at least three abutting points between the outer side of the first inner wall 102, the bottom wall 101 and the lower end head 220, and the first and the last abutting points form a polygonal support structure. In this way, not only the structural strength of the bending piece 121a can be improved, and the plug-in tightness of the bending piece 121a and the groove structure 111 can be ensured, but also a waterproof position can be formed at the first inner wall 102, the bottom wall 101 and the lower end head 220 respectively, so as to improve the waterproof performance of the plug-in fit between the bending piece 121a and the groove structure 111.

[0038] Exemplarily, in an embodiment, the end of the bending piece 121a that is suspended is bent towards the direction close to the groove structure 111, so that the end of the bending piece 121a that is suspended is in V shape or inverted V shape. Preferably, the inverted V shape structure is adopted, that is, the bending piece 121a is configured to have a small upper end cross section and a large lower end cross section, so as to facilitate the insertion of the bending piece 121a into the groove structure 111. Specifically, the vertex of the inverted V-shaped bending piece 121a abuts against the bottom wall 101, and the two ends of the inverted V-shaped bending piece 121a abut against the first inner wall 102 and the lower end head 220 respectively. The two end points of the opening end of the V-shaped bending piece 121a abut against the bottom wall 101, the first inner wall 102 or the second inner wall 103 respectively, and the vertex of the V-shaped bending piece 121a abuts against the lower end head 220 or connects with another bending segment.

[0039] Of course, not limited to this, in other embodiments, the bending piece 121a can also be configured in a structure containing multiple V-shaped or inverted V-shaped, such as M-shaped, W-shaped, etc.

[0040] In an embodiment, the part of the bending piece 121a located inside the groove structure 111 is defined as a first part 121b, and the part of the bending piece 121a extending out of the groove structure 111 is defined as a second part 121c, and the cross-sectional area of the first part 121b is smaller than the cross-sectional width of the groove structure 111. In this way, it is convenient for the first part 121b to be inserted into the groove structure 111.

[0041] In an embodiment, the cross-sectional width of the bending piece 121a and the connecting part 122 is greater than or equal to the cross-sectional width of the groove structure 111, so that the plug-in part 121 can be elastically deformed by being extruded during the plug-in cooperation with the groove structure 111, and tightly abuts against the groove structure 111 under the action of the elastic force. Specifically, the cross-sectional area of the first part 121b can be smaller than the cross-sectional width of the groove structure 111, and the cross-sectional width of the second part 121c can be greater than or equal to the cross-sectional width of the groove structure 111; or, the cross-sectional width of the first part 121b and the second part 121c can be smaller than the cross-sectional width of the groove structure 111, and the cross-sectional width at the connecting part 122 can be equal to the cross-sectional width of the groove structure 111.

Optionally, the second rain blocking protrusion 116 includes two folded edges connected to form an acute angle structure.

[0043] In an embodiment, along the direction from the upper plate 110 to the lower plate 120, the cross-sectional width of the groove structure 111 has a tendency to increase. That is, the groove structure 111 has a flared shape. In this way, during the hoisting process of the two sections of the shaft 200, it is convenient for the plug-in part 121 to be connected with the groove structure 111.

[0044] Optionally, in an embodiment, along the direction from the bottom wall 101 to the opening of the groove structure 111, the first inner wall 102 has a tendency to extend outwardly. That is, the first inner wall 102 of the groove structure 111 extends obliquely downward with respect to the shaft 200, so as to be beneficial to avoid rainwater entering the inside of the groove structure 111 along the first inner wall 102, thereby being beneficial to further improve the waterproof performance of the drip plate connecting structure 10.

[0045] In an embodiment, the upper plate 110 comprises a first plate 112 and a second plate 113, the second plate 113 has an opening 113b at one end, and the first plate 112 is inserted into the opening 113b from the side of the second plate 113 and forms a recess structure 111 together with the second plate 113.

[0048] In the process of assembling the upper plate 110, the third bending part 112a can be first attached and connected to the outer side, the lower side and at least part of the inner side of the second keel 211; then the fifth bending part 113a is crimped on the fourth bending part 112b, and one end of the fifth bending part 113a extends out of the fourth bending part 112b to attach and connect the upper side of the second keel 211. It can be understood that in the process of assembling the upper plate 110, the shape of the fifth bending part 113a cooperates with the fourth bending part 112b to play a positioning role. Optionally, the first plate 112 and the second plate 113 are configured as an integrally formed bending piece.

[0049] In an embodiment, the upper plate 110 has at least one first rainproof protrusion 114. The first rainproof protrusion 114 protrudes in a direction away from the shaft 200.
