The elevator guide rail body is installed on the inner wall of the hoistway through an installation structure, and the installation structure is used to provide an inclined supporting force to any guide rail splicing block 100.

[0028] The elevator guide rail is installed on the inner wall of the hoistway through an installation structure. The installation structure can provide a lateral supporting force to the elevator guide rail, so that during the operation of the elevator car, if the center of gravity of the elevator car changes due to the standing position of the personnel, the installation structure can maintain a high structural strength to offset the lateral tilting force generated by the elevator car, thereby ensuring the good operation of the elevator car.

[0029] Among them, one end of the guide rail splicing block 100 in the length direction is provided with a plug-in groove 140, and the other end of the guide rail splicing block 100 in the length direction is provided with a plug-in block 150. Adjacent guide rail splicing blocks 100 are spliced by the cooperation of the plug-in block 150 and the plug-in groove 140.

[0030] The elevator guide rail body is composed of a plurality of guide rail splicing blocks 100 spliced end to end in sequence. During installation, the staff can splice adjacent guide rail splicing blocks 100 through the cooperation of the plug-in block 150 and the plug-in groove 140, which is relatively convenient.

[0031] Embodiment 2:

[0032] See Figures 4-7 , an installation structure for installing an elevator guide rail, which is used for the installation of an elevator guide rail described in Embodiment 1 at the inner wall of the hoistway. It includes an installation structure body 200. The installation structure body 200 includes a structural member and a support member 250. Each guide rail splicing block 100 is equipped with two installation structure bodies 200. One side of the structural member is connected to the inner wall of the hoistway, and the other side of the structural member is connected to the guide rail splicing block 100; the support member 250 is cooperated with the structural member to form a triangular structural support.

[0033] During actual installation, the support member 250 is arranged below the structural member, so that during the operation of the elevator car, if the center of gravity of the elevator car changes due to the standing position of the personnel, the triangular structural support formed by the support member 250 and the structural member can better offset the lateral tilting force generated by the elevator car, improve the installation structure strength and ensure the stability of the elevator car during operation.

[0034] Specifically, the structural member includes a structural plate 210 in the shape of an I-beam. The structural plate 210 includes a first mounting plate 211, a second mounting plate 212, and a third mounting plate 213. The first mounting plate 211 and the second mounting plate 212 are respectively arranged at both ends of the third mounting plate 213 in the length direction. A spacer column 220 is provided in the middle of the third mounting plate 213. The spacer column 220 is perpendicular to the plate surface of the structural plate 210. A first fitting plate 230 and a second fitting plate 240 for cooperating with the first fitting plate 230 are provided at the end of the spacer column 220. A first card slot 130 for accommodating the first fitting plate 230 is provided on one side of the back plate 110, and a second card slot 160 for accommodating the second fitting plate 240 is provided on the other side of the back plate 110. The first fitting plate 230 and the second fitting plate 240 are connected by a bolt assembly.

[0035] During actual installation, first, the structural plate 210 is installed and positioned at the inner wall of the hoistway according to the design. Subsequently, the first fitting plate 230 and the second fitting plate 240 are separated, so that the first card slot 130 of the guide rail splicing block 100 is aligned with the first card slot 130. Then, the second fitting plate 240 is snapped into the second card slot 160. Finally, the guide rail splicing block 100 is installed at the installation structure body 200 through the bolt assembly.

[0036] Among them, in order to improve the connection strength between the guide rail splicing block 100 and the installation structure body 200, a first structural column 260 and a second structural column 270 are symmetrically arranged along the axial direction of the spacer column 220 on the side of the first fitting plate 230 facing the spacer column 220. A first thread groove is provided along the axial direction of the first structural column 260, and a second thread groove is provided along the axial direction of the second structural column 270. An axial groove is provided through the spacer column 220 along the axial direction. The ends of the first thread groove and the second thread groove communicate with the axial groove. The bolt assembly includes a first bolt 310 threadedly connected to the first thread groove, a second bolt 320 threadedly connected to the second thread groove, and a mounting rod 330 installed in the axial groove. An annular limiting groove 331 is provided on the rod wall of the corresponding section of the mounting rod 330. The ends of the first bolt 310 and the second bolt 320 abut against the annular limiting groove 311.

[0038] In addition, in order to better offset the lateral tilting force generated by the change of the center of gravity of the elevator car, the support member 250 includes a fourth mounting plate 251. The fourth mounting plate 251 is provided with a stepped groove 252 for covering the second mounting plate 212. One side of the fourth mounting plate 251 is provided with a support rod 253. The support rod 253 is inclined and the end of the support rod 253 is provided with a U-shaped support block 254. The spacer column 220 is correspondingly arranged at the support block 254.

[0039] When a lateral tilting force occurs to the elevator car, the support member 250 can better support the structural member and offset the lateral tilting force of the elevator car, thereby better improving the structural strength of the structural member and ensuring the good operation of the elevator car.

[0040] Among them, the length of the first mounting plate 211 is less than the length of the second mounting plate 212, and the structure is reasonable. Moreover, the lower part of the structural plate 210 has a large contact area with the inner wall of the hoistway. Cooperating with the support member 250, the good operation of the elevator car is better ensured.

[0041] Among them, both ends of the second mounting plate 212 are provided with reinforcing plates 280 that are inclined and connected to the side wall of the third mounting plate 213, which better improves the structural strength of the structural plate 210.

[0042] The above content described in this specification is only an example of the present utility model. Those skilled in the technical field to which the present utility model belongs can make various modifications or supplements to the described specific embodiments or use similar ways to replace them. As long as it does not deviate from the content of the specification of the present utility model or exceed the scope defined by the claims of the present utility model, it shall fall within the protection scope of the present utility model.
