[0046] Reference will now be made in detail to various embodiments of the present application, examples of which are illustrated in the accompanying drawings and described below. While the present application will be described in conjunction with the exemplary embodiments, it should be understood that the present application is not limited to these exemplary embodiments. On the contrary, the present application is intended to cover various alternatives, modifications, equivalents and other embodiments that can be included within the spirit and scope of the present application as defined by the appended claims.

[0047] For the convenience of explanation and precise definition of the appended claims, the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom" are used to describe the features of the exemplary embodiments with reference to the positions of the features shown in the drawings.

[0048] The present application will be described below in conjunction with Figure 1 and Figure 2 The mounting device of the elevator guide rail provided by the present application will be described in detail.

[0049] The hoistway of the elevator includes four elevator guide rails and a car, and the car can move up and down along the elevator guide rails in the hoistway. As shown in Figure 1 , three elevator guide rails 11, 12, 13 are located on the same side of the elevator, and the other elevator guide rail 14 is located on the other side of the elevator. The mounting device of the elevator guide rail is arranged on the side where the three elevator guide rails 11, 12, 13 are located and below the three elevator guide rails 11, 12, 13. By using the mounting device of the elevator guide rail (hereinafter referred to as the mounting device), the installer can spend less time and effort to adjust the bottom ends of the elevator guide rails 11, 12, 13 to be on the same horizontal plane during the installation of the elevator.

[0050] In conjunction with reference to Figures 1 to 3 , first refer to Figure 1 and 2 , the mounting device includes a bottom plate 2 and adjusting bolts 31, 32, 33. Among them, the bottom plate 2 is a flat plate structure, which can be integrally formed by stamping process. The adjusting bolts 31, 32, 33 can support the bottom plate 2 to ensure that the bottom plate 2 can still remain parallel to the horizontal plane on the uneven surface. When installing the elevator, the mounting device is arranged in advance at the bottom of the hoistway, and if the bottom of the hoistway is not flat enough, the adjusting bolts 31, 32, 33 can be adjusted to ensure that the bottom plate 2 is parallel to the horizontal plane. At this time, the elevator guide rails 11, 12, 13 are arranged on the bottom plate 2, which can ensure that the bottom ends of the elevator guide rails 11, 12, 13 are on the same horizontal plane, thereby ensuring that the heights of the elevator guide rails 11, 12, 13 are consistent.

[0051] The bottom plate 2 includes a main body part 22 and a side plate part 21.

[0052] Referring to Figure 3 , the main body portion 22 is a long strip-shaped plate structure and is arranged in the hoistway in the front-rear direction. The front end portion of the main body portion 22 is defined as a front mounting portion 221, which is used to connect the bottom end of the elevator guide rail 11. The rear end portion of the main body portion 22 is defined as a rear mounting portion 222, which is used to connect the bottom end of the second elevator guide rail 12. The width (i.e., the dimension in the left-right direction) of the main body portion 22 is set to be slightly larger than the dimension of the bottom end of the elevator guide rails 11, 12; the length (i.e., the dimension in the front-rear direction) of the main body portion 22 is set to be slightly larger than the distance of the elevator guide rails 11, 12 in the front-rear direction (the distance between the frontmost side of the elevator guide rail 11 and the rearmost side of the elevator guide rail 12).

[0053] The side plate portion 21 is arranged at one side of the main body portion 22, and the side plate portion 21 is defined with a side mounting portion 211, which is used to connect the elevator guide rail 13. In the hoistway, the side plate portion 21 is located at the left side or the right side of the main body portion 22. When the car is located at the left side of the main body portion 22, the side plate portion 21 is located at the left side of the main body portion 22; when the car is located at the right side of the main body portion 22, the side plate portion 21 is located at the right side of the main body portion 22.

[0054] The adjusting bolt 31 is arranged at a position close to the front mounting portion 221 of the main body portion 22, the adjusting bolt 32 is arranged at a position close to the rear mounting portion 222 of the main body portion 22, and the adjusting bolt 33 is arranged at the side plate portion 21. Each of the adjusting bolts 31, 32, 33 has a portion located below the bottom plate 2. Moreover, the portion of the adjusting bolts 31, 32, 33 located below the bottom plate 2 can be adjusted in the up-down direction, so that the bottom plate 2 can be kept parallel to the horizontal plane when placed on an uneven surface. In other words, by adjusting the adjusting bolts 31, 32, 33, the bottom plate 2 can be stably and horizontally placed on the bottom of the hoistway, and the front mounting portion 221, the rear mounting portion 222, and the side mounting portion 211 can be kept at the same horizontal plane at the bottom of the hoistway, i.e., the bottom ends of the elevator guide rails 11, 12, 13 can be arranged at the same horizontal plane, thereby ensuring the uniform height of the elevator guide rails 11, 12, 13.

[0055] Referring to Figure 3 , adjusting screw holes 223, 224, 212 matching the adjusting bolts 31, 32, 33 are arranged on the bottom plate 2, and the adjusting screw holes 223, 224, 212 penetrate the bottom plate 2 in the up-down direction. In combination with the reference Figure 2 and Figure 3 , the adjusting bolts 31, 32, 33 can be screwed into the adjusting screw holes 223, 224, 212 and pass through the bottom plate 2, so that the lower end portions of the adjusting bolts 31, 32, 33 can be located below the bottom plate 2 to support the bottom plate 2.

[0056] Specifically, before installing the elevator guide rails 11, 12, 13, the installation device is first set at the position corresponding to the elevator guide rails 11, 12, 13 on the bottom of the hoistway. At this time, the support bolts 31, 32, 33 have not yet passed through the bottom plate 2, and then the installation personnel detect whether the bottom plate 2 is horizontal by using a level or other measuring tools. If the bottom plate 2 is already horizontal, there is no need to adjust the adjusting bolts 31, 32, 33 (and even the adjusting bolts 31, 32, 33 can not be installed on the bottom plate 2). If the bottom plate 2 is inclined, the corresponding adjusting bolts can be adjusted so that the bottom plate 2 can be kept horizontal.

[0057] For example, when the height of the side mounting portion 211 is lower than that of the front mounting portion 221 and the rear mounting portion 222, the adjusting bolt 33 passing through the bottom plate 2 can be adjusted so that the adjusting bolt 33 can support the bottom plate 2 at the side plate portion 21, so that the bottom plate 2 can be kept in a horizontal state. When the bottom plate 2 is supported to be horizontal by the adjusting bolt, there will be a gap between the side plate portion 21 and the bottom of the hoistway, and the installation personnel can insert a shim into the gap to provide sufficient support force to the bottom plate 2.

[0058] It is worth mentioning that, continuing to refer to Figure 1 , after the elevator guide rails 11, 12, 13 are installed, a transverse support 6 will also be arranged in the hoistway. The transverse support 6 can connect the elevator guide rails 11, 12, 13 and the side wall of the hoistway to prevent the elevator guide rails 11, 12, 13 from being inclined. At the same time, the transverse support 6 can also bear the weight of the elevator guide rails 11, 12, 13 to reduce the pressure of the elevator guide rails 11, 12, 13 on the bottom plate 2.

[0059] The adjusting threaded hole 223 is arranged at a position of the main body portion 22 close to the front mounting portion 221, and the adjusting threaded hole 223 corresponds to the adjusting bolt 31. The adjusting threaded hole 224 is arranged at a position of the main body portion 22 close to the rear mounting portion 222, and the adjusting threaded hole 224 corresponds to the adjusting bolt 32. The two adjusting threaded holes 212 are arranged on the side plate portion 21, and the two adjusting threaded holes 212 are respectively located on the front and rear sides of the side mounting portion 211, and each adjusting threaded hole 212 corresponds to an adjusting bolt 33. Among them, the adjusting threaded hole 223 and the adjusting threaded hole 224 are located on the side of the main body portion 22 away from the side plate portion 21 (i.e. the right side shown in the figure), and the adjusting threaded hole 212 is located on the side of the side plate portion 21 away from the main plate portion 22.

[0060] The adjusting bolts 31, 32, 33 can be screwed into the corresponding adjusting threaded holes 223, 224, 212 from top to bottom, and can respectively pass through the bottom of the main body part 22 and the side plate part 21. After the mounting device is arranged on the shaft bottom, if the shaft bottom is uneven and causes the bottom plate 2 to be inclined, the heights of the front mounting part 221, the rear mounting part 222 and the side mounting part 211 in the up-down direction are inconsistent. At this time, the length of the adjusting bolt passing through the bottom plate 2 (the length of the adjusting bolt below the bottom plate 2 (the main body part 22 or the side plate part 21)) can be adjusted, so that the heights of the front mounting part 221, the rear mounting part 222 and the side mounting part 211 are adjusted to be consistent, so that the bottom plate 2 can be placed horizontally on the shaft bottom.

[0061] With reference to the drawings again, Figure 3 The mounting device further comprises a guide rail mounting assembly 4 which can be fixed on the bottom plate 2 and is used for connecting the elevator guide rails 11, 12, 13. The guide rail mounting assembly 4 is arranged on each of the front mounting part 221, the rear mounting part 222 and the side mounting part 211, and is respectively used for connecting the elevator guide rails 11, 12, 13.

[0062] The guide rail mounting assembly 4 comprises a mounting plate 41, a pressing bolt 42 and a nut 43. The mounting plate 41 is fixedly connected on the bottom plate 2, and the pressing bolt 42 and the nut 43 cooperate to press the elevator guide rails 11, 12, 13 against the mounting plate 41, so that the elevator guide rails 11, 12, 13 can be respectively connected to the guide rail bottom plate 2 through the corresponding guide rail mounting assembly 4.

[0063] The mounting plate 41 comprises a first part 411 and a second part 412 which are perpendicular to each other.

[0064] The first part 411 is formed with a first mounting hole 413, and the mounting plate 41 is fixed on the bottom plate 2 by means of the first mounting hole 413. Specifically, the front mounting part 221, the rear mounting part 222 and the side mounting part 211 are respectively formed with a second mounting hole corresponding to the first mounting hole 413, and the second mounting hole is provided with a mounting thread. The three mounting plates 41 are respectively fixed on the front mounting part 221, the rear mounting part 222 and the side mounting part 211 by means of the mounting bolt 5.

[0065] With reference to the drawings again, Figure 3 The fixing structure of the guide rail mounting assembly 4 will be described below by taking the guide rail mounting assembly 4 arranged on the side plate part as an example.

[0066] The second mounting hole 213 is formed with a mounting thread. The mounting bolt 5 can pass through the first mounting hole 413 from top to bottom, and then be screwed into the second mounting hole 213. Thus, the mounting plate 41 can be fixed to the side mounting portion 211 by the mounting bolt 5. It is worth mentioning that when the mounting plate 41 is fixed to the side mounting portion 211 by the mounting bolt 5, the length of the mounting bolt 5 is not enough to pass out of the second mounting hole 213, so that the lower surface of the bottom plate 2 remains flat (not considering the adjusting bolt).

[0067] The guide rail mounting assembly 4 arranged at the front mounting portion 221 and the rear mounting portion 222 is also connected in the above manner. Since the structures of the three positions are similar, details are not repeated herein.

[0068] The first portion 411 is further formed with a mounting groove 414 for accommodating the end of the elevator guide rail 11, 12 or 13. The shape of the mounting groove 414 corresponds to the shape of the bottom of the elevator guide rail 11, 12 or 13, and the bottom end of the elevator guide rail 11, 12 or 13 can be embedded in the mounting groove 414.

[0069] The second portion 412 is formed with a through hole 415, and the compression bolt 42 can pass through the through hole 415 and then be connected with the nut 43. Specifically, after the bottom end of the elevator guide rail 11, 12 or 13 is embedded in the mounting groove 414, the through hole 415 is not blocked by the elevator guide rail 11, 12 or 13, and then the compression bolt 42 is passed through the through hole 415, so that the bottom end of the elevator guide rail 11, 12 or 13 is connected to the second portion 412 of the mounting plate 41. Referring to Figure 4 Taking the elevator guide rail 13 as an example, the compression bolt 42 includes a compression end portion 421 and a stud portion 422. Referring to Figs. 3 and Figure 4 The stud portion 422 can pass through the through hole, and the compression end portion can abut against the elevator guide rail 13. The nut can be connected to the stud portion of the compression bolt and be tightened, so that the compression end portion can abut against the elevator guide rail 13, and thus the bottom end of the elevator guide rail 13 is connected to the second portion 412.

[0070] In particular, the through hole 415 is provided in two, which are respectively located on the two sides of the second portion 412 in the horizontal direction. Specifically, in the front mounting end portion and the rear mounting end portion, the two through holes 415 are distributed on the two sides of the second portion 412 in the left-right direction; in the side mounting portion, the two through holes 415 are distributed on the two sides of the second portion 412 in the front-rear direction.

[0071] The utility model also provides an elevator which adopts the mounting device of the elevator guide rail. The other structures and mounting modes of the elevator are the same as those of the prior art, and details are not repeated herein.

[0072] According to the mounting device of the elevator guide rail and the elevator provided by the utility model, the installer can spend less time and energy to adjust the bottom ends of the elevator guide rails 11, 12 and 13 to be on the same horizontal plane, thereby ensuring the consistency of the heights of the top ends of the elevator guide rails 11, 12 and 13.

[0073] The foregoing description of the utility model specific example embodiment presented is for the purpose of illustration and description. The foregoing description is not intended to be exhaustive or to limit the utility model to the precise form disclosed, and obviously many changes and modifications are possible according to the above teachings.
