[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 As shown, an embodiment of the present disclosure provides an elevator guide rail connection assembly 200, which is used to connect two sections of guide rail units 100 in an elevator guide rail. By improving the connection assembly 200, the guide rail unit can be removed in situ. Thus, it is avoided to completely remove the elevator guide rail on one side, and the elevator inspection and maintenance efficiency is significantly improved.

[0027] Based on the above concept, Figure 2 ,3 As shown in FIG. 4 , the elevator guide rail connection assembly 200 of this embodiment includes: a first connection member 21 , a second connection member 22 and a third connection member 23 .

[0028] Among them, the first connecting member 21 is arranged at one end of the guide rail unit 100, and the first connecting member 21 has a fixed state and a sliding state; the second connecting member 22 is arranged at the other end of the guide rail unit 100; any two adjacent guide rail units 100 are detachably connected through the third connecting member 23.

[0029] When the first connecting member 21 is in a fixed state, it cooperates with the second connecting member 22 to provide guidance for the connection of two adjacent guide rail units 100. When the first connecting member 21 is in a sliding state, it retreats into the guide rail unit 100, so that the guide rail unit 100 can be removed in situ. Thus, it is avoided to completely remove the elevator guide rails on one side, and the efficiency of elevator inspection and maintenance is significantly improved.

[0030] Specifically, the first connecting member 21 includes: a first base plate 211 and a column 212 arranged on the first base plate 211. The first base plate 211 is detachably connected to one end of the guide rail unit 100, and a mounting groove is provided on one side edge of the first base plate 211; the column 212 is partially arranged in the mounting groove and is kept perpendicular to the first base plate 211. Among them, the column 212 can be connected to the mounting groove by welding or mechanical connection. The column 212 is partially accommodated in the guide part, and the rest of the column 212 extends from the guide part. In this way, the part of the column 212 accommodated in the guide part can support and strengthen the guide part, and the part thereof extending from the guide part can guide when the two guide rail units 100 are docked. In one embodiment, the column 212 can be set as a rectangular column.

[0031] The second connecting member 22 includes a second bottom plate 221; the second bottom plate 221 is detachably connected to the other end of the guide rail unit 100, and a guide groove 222 is provided on one side edge of the second bottom plate 221, and the guide groove 222 can cooperate with the portion of the column 212 extending from the guide portion. With such a configuration, when two guide rail units 100 are docked, the portion of the column 212 extending from the guide portion can penetrate into the adjacent guide rail unit 100 and cooperate with the guide groove 222 of the second bottom plate 221 in the adjacent guide rail unit 100, thereby achieving guidance when the two guide rail units 100 are docked. In one embodiment, the guide groove 222 can be configured as a rectangular groove that cooperates with the rectangular column.

[0032] In order to realize the detachable connection of the first connecting member 21 and the second connecting member 22 in the guide rail unit 100, a rivet hole 201 and a screw hole 202 are provided on the first bottom plate 211 and the second bottom plate 221. At this time, the first bottom plate 211 and the second bottom plate 221 are detachably connected to the guide rail unit 100 through the rivet holes 201 thereon. That is, by providing rivets 24, the rivets 24 pass through the corresponding rivet holes 201, and then the first bottom plate 211 and the second bottom plate 221 are detachably fixed to the guide rail unit 100, so that the first connecting member 21 can be in a fixed state. In one embodiment, the rivet holes 201 can be set to two, and in this case, the two rivet holes 201 can be symmetrically distributed on the bottom plate.

[0033] In order to enable the first connecting member 21 to be in a sliding state, the rivet hole 201 on the first bottom plate 211 can be set to be waist-shaped. At this time, when a thrust is applied to the first connecting member 21, it can be retreated along the waist-shaped rivet hole 201 to the guide rail unit 100 where it is located. Therefore, since the interference between the first connecting member 21 and the adjacent guide rail unit 100 is eliminated, the adjacent guide rail unit 100 can be removed in situ. Alternatively, a waist-shaped rivet hole 201 can also be set on the guide rail unit 100. At this time, under the corresponding force, the first connecting member 21 can also be retreated along the waist-shaped rivet hole 201 to the guide rail unit 100 where it is located.

[0034] The first bottom plate 211 and the second bottom plate 221 can also assist the third connecting member 23 to detachably connect any two adjacent guide rail units 100 through the screw holes 202 thereon. The third connecting member 23 is explained below in conjunction with its structure. The third connecting member 23 includes a connecting plate 231, and structures for detachable connection are respectively provided at both ends of the connecting plate 231. The connecting plate 231 detachably connects two adjacent guide rail units 100 through the structures at both ends.

[0035] In one embodiment, the structure is a through hole opened on the connecting plate 231. In this case, a bolt 25 is provided as a locking member. As described above, the first connecting member 21 and the second connecting member 22 are provided with screw holes 202. The bolt 25 passes through the through holes on the connecting plate 231 and the guide rail unit 100 and cooperates with the screw holes 202 to detachably connect two adjacent guide rail units 100. At the same time, the first connecting member 21 and the second connecting member 22 are also locked in the corresponding guide rail unit 100. The screw holes 202 can be set to three, and in this case, the three screw holes 202 are located on one side of the above-mentioned rivet hole 201 and distributed on the three vertices of the triangle.

[0036] In addition, in this embodiment, the connecting plate 231 is optimized so that the connecting plate 231 has better flatness, which is beneficial for connecting two adjacent guide rail units 10. Specifically, the two side edges 2310 and 2311 of the connecting plate 231 are warped in opposite directions by stamping, and the warping on one side can fit the side of the guide rail unit 10, so that the reverse warping structures on both sides can disperse and balance the stamping force, thereby achieving better flatness of the connecting plate 231.

[0037] In summary, in the elevator guide rail connection assembly of the utility model, the first connection member has a fixed state and a sliding state. When in the fixed state, it can ensure the firm connection between the guide rail units; and when in the sliding state, the first connection member retreats into the guide rail unit, so that the guide rail unit can be removed in situ. Thus, it is avoided to completely remove the elevator guide rails on one side, and the efficiency of elevator inspection and maintenance is significantly improved.
