TECHNICAL FIELD

[0001] The utility model relates to a kind of installation tools and elevator installation system, more specifically, a kind of installation tool for installing lower sill and upper sill and corresponding elevator installation system. BACKGROUND

[0002] In the process of installing lower sill and upper sill of elevator system, the lower sill of multiple landings needs to be aligned with each other, and similarly, the upper sill of multiple landings also needs to be aligned with each other. In the prior art, the distance between the lower sill and the upper sill and the guide rail needs to be measured at each landing or a plumb line is used to ensure the alignment between multiple lower sills and the alignment between multiple upper sills. However, measuring the distance between the lower sill and the upper sill and the guide rail requires a large amount of tape measure, resulting in low installation efficiency. If a plumb line is used to determine the installation position of the lower sill and the upper sill, the plumb line may accidentally move due to various factors (e.g., being blown by the wind or being accidentally touched by the operator, etc.), resulting in inaccurate installation position determined by the plumb line.

[0003] Therefore, it is desirable to provide an installation tool to improve the above-mentioned deficiencies in the prior art. SUMMARY

[0004] According to a first aspect of the present utility model, an installation tool for an elevator system is provided, comprising: a fixing member configured to be fixed to a guide rail of the elevator system, the guide rail extending in a vertical direction; a positioning arm movable relative to the fixing member in a first direction perpendicular to the vertical direction, the positioning arm having an elongated main body extending in the first direction, one end of the positioning arm being configured to contact and position a lower sill and an upper sill of the elevator system; and a first fastening member configured to detachably fasten the positioning arm to the fixing member.

[0005] According to this scheme, the positioning arm can be used to determine the installation position of the upper sill and the lower sill, without the need to use a measuring tool to determine the installation position of the upper sill and the lower sill for each landing of the upper sill and the lower sill, thereby simplifying the installation process of the upper sill and the lower sill and improving the installation position accuracy of the upper sill and the lower sill.

[0006] In some schemes, the positioning arm can further include a positioning member fixed to one end of the main body, the positioning member being configured to contact and position the lower sill and the upper sill, the positioning member having a stepped shape, the positioning member having a first surface and a second surface perpendicular to the first direction, the first surface being closer to the fixing member relative to the second surface, and the first surface being located above or below the second surface.

[0007] According to this scheme, the first surface and the second surface of the positioning member can be used to determine the installation position of the lower sill or the upper sill, respectively, making the installation operation simpler.

[0008] In some embodiments, the first surface can be configured to contact and position the lower sill, and the second surface can be configured to contact and position the upper sill.

[0009] In some embodiments, the fixing member can have a first portion, the first portion being a hollow tube extending in a first direction, and the main body of the positioning arm penetrating through the first portion in the first direction.

[0010] According to the embodiments, the positioning arm can move in the first portion, so as to determine the installation position of the lower sill or the upper sill.

[0011] In some embodiments, the first portion can be provided with a first fastening hole, and a first fastener is inserted into the first fastening hole.

[0012] According to the embodiments, after the installation position of the lower sill or the upper sill of a certain landing is determined, the positioning arm can be fixed to the fixing member by the first fastener, so that the length of the positioning arm extending from the fixing member remains unchanged, thereby ensuring the alignment between the upper sills and the alignment between the lower sills when the upper sills or the lower sills of other landings are installed.

[0035] In order to make the purpose, scheme and advantages of the technical scheme of the present application more clear, the technical scheme of the present application embodiment will be described clearly and completely in the following with reference to the drawings of the specific embodiments of the present application. Unless otherwise specified, the terms used herein have the meanings commonly used in the art. The same reference signs in the drawings represent the same components.

[0036] For the sake of clarity, unless otherwise explicitly stated, the orientation terms appearing in this text have the following meanings: the vertical direction refers to the extension direction of the car guide rail and the counterweight guide rail, the first direction refers to the extension direction of the positioning arm, and the second direction refers to the direction perpendicular to both the vertical direction and the first direction.

[0037] Figure 1A schematic view of a mounting tool 100 according to an embodiment of the present application is shown, the mounting tool is used for installation of upper and lower sills of an elevator system. The elevator system comprises a car and car guide rails and counterweight guide rails, the car travels along the car guide rails within an elevator shaft to transport passengers and goods, the counterweight travels along the counterweight guide rails. The car has a car door, and at each landing, a corresponding hall door is also provided. When the car travels to a certain landing, the car door and the hall door are opened at the same time, thereby allowing passengers and goods to enter and exit the car. When the car departs from the landing, the car door and the hall door are closed at the same time to prevent passengers inside the car and on the landing from accidentally falling into the elevator shaft, respectively. In order to make the opening and closing movement of the hall door more stable, it is necessary to provide the upper and lower sills, the upper sill is used to guide the movement of the upper part of the hall door, and the lower sill is used to guide the movement of the lower part of the hall door. During the installation of the upper and lower sills, the corresponding upper sills of multiple landings need to be aligned with each other, and the corresponding lower sills of multiple landings also need to be aligned with each other. For this purpose, the present application provides a mounting tool 100 for conveniently aligning the corresponding upper sills of multiple landings with each other, and the corresponding lower sills of multiple landings are also aligned with each other.

[0038] The mounting tool 100 mainly comprises a fixing member 110, a positioning arm 120 and a first fastener 132, the fixing member 110 is fixed to the car guide rail, the positioning arm 120 is used to determine the installation position of the upper and lower sills, and the first fastener 132 is used to detachably fasten the positioning arm 120 to the fixing member 110. It should be noted that although in the present embodiment, the fixing member 110 is fixed to the car guide rail, the present application is not limited thereto, and the fixing member 110 can also be fixed to the counterweight guide rail. The positioning arm 120 is movable relative to the fixing member 110 in a first direction, the positioning arm 120 has an elongated main body extending in the first direction, one end of the positioning arm 120 is configured to contact the upper and lower sills of the elevator system, thereby determining the installation position of the upper and lower sills. According to the above arrangement, it is not necessary to use a measuring tool to determine the installation position of the upper and lower sills for the upper and lower sills of each landing, thereby simplifying the installation process of the upper and lower sills, reducing the time required for installing the upper and lower sills, and improving the installation position accuracy of the upper and lower sills.

[0039] Specifically, the positioning arm 120 may include a main body 122 and a positioning member 124. The positioning member 124 is fixed to one end of the main body 122 (e.g., by screws). The positioning member 124 is configured to contact the upper and lower sills of the elevator system, thereby determining the installation positions of the upper and lower sills. Preferably, the positioning member 124 may have a stepped shape and has a first surface 126 and a second surface 128 perpendicular to a first direction. The first surface 126 is closer to the fixing member 110 than the second surface 128, and the first surface 126 and the second surface 128 are offset along the first direction (i.e., the first surface 126 is located above or below the second surface 128). The distance between the first surface 126 and the second surface 128 along the first direction can be designed based on the specific installation positions of the upper and lower sills. For example, if the horizontal distance between the upper and lower sills is L, then the distance between the first surface 126 and the second surface 128 along the first direction can be designed to be L.

[0040] The first surface 126 can be configured to contact the lower sill, thereby determining the installation position of the lower sill. The second surface 128 can be configured to contact the upper sill, thereby determining the installation position of the upper sill. Alternatively, the first surface 126 can be configured to contact the upper sill, thereby determining the installation position of the upper sill. The second surface 128 can be configured to contact the lower sill, thereby determining the installation position of the lower sill. Because the first surface 126 and the second surface 128 can simultaneously determine the installation positions of the upper and lower sills, it is unnecessary to perform two separate operations to determine the installation positions for the upper and lower sills, thereby further simplifying the installation process of the upper and lower sills. Furthermore, because there is a height difference between the first surface 126 and the second surface 128, the positioning element 124 will not interfere with the installation of the upper or lower sill.

[0041] like Figure 2 As shown, the fixing member 110 may have a first part 112 and a second part 114. The first part 112 is used to accommodate the positioning arm 120 so that the positioning arm 120 can move relative to the fixing member 110 in a first direction, and the second part 114 is used to fix the fixing member 110 to the car guide rail.

[0042] The first part 112 is a hollow tube extending along a first direction, and the main body 122 of the positioning arm 120 passes through the first part 112 along the first direction. Therefore, the positioning arm 120 can move within the first part 112 to determine the installation position of the lower or upper sill.

[0043] In addition, the first part 112 can be provided with a first fastening hole into which a first fastener 132 is inserted to fasten the positioning arm 120 to the fixing member 110. After determining the installation position of the landing or the landing of a certain landing, the positioning arm 120 can be fixed to the fixing member 110 by the first fastener 132, so that the length of the positioning arm 120 extending from the fixing member 110 remains unchanged, thereby ensuring the alignment between the landings and the alignment between the landings when installing the landings or the landings of other landings.

[0044] The second part 114 protrudes from the first part 112 in a second direction (i.e., a direction towards the car guide rail), and the second part 114 can be provided with a groove 116 configured to receive a portion of the car guide rail, thereby fixing the second part 114 to the car guide rail. Preferably, one side of the groove 116 can be provided with a fixing plate 118 extending through the groove 116 in the vertical direction, and the fixing plate 118 is configured to contact the car guide rail. By the fixing plate 118, the contact area between the fixing member 110 and the car guide rail can be increased, thereby making the fixation between the fixing member 110 and the car guide rail more reliable.

[0045] In addition, the second part 114 can be provided with a second fastening hole on the other side (i.e., the side opposite to the side where the fixing plate 118 is located) of the groove 116, and a second fastener 134 is inserted into the second fastening hole to fix the fixing member 110 to the car guide rail.

[0046] The specific steps of installing the landings and the landings of the elevator system using the installation tool 100 according to the embodiments of the present application will be described below:

[0047] The landings and the landings are installed at the first landing (e.g., 1st floor), and a plumb line or laser is used to ensure that the position of the landings and the landings installed at the first landing is accurate. First, the second fastener 134 is tightened to fix the fixing member 110 to the car guide rail, and the first fastener 132 is loosened to enable the positioning arm 120 to move relative to the fixing member 110. Then the positioning arm 120 is moved towards the landings and the landings of the first landing until one end of the positioning arm 120 contacts the landings and the landings (specifically, for example, the first surface 126 contacts the landing, and the second surface 128 contacts the landing). Then the first fastener 132 is tightened so that the positioning arm 120 can no longer move relative to the fixing member 110. Finally, the second fastener 134 is loosened to detach the installation tool 100 from the car guide rail for installation of the landings and the landings of other landings.

[0048] The upper and lower sills are sequentially installed at other landings (e.g., 2nd floor, 3rd floor, 4th floor, etc.). The second fastener 134 is first tightened to fix the installation tool 100, which has been disassembled, to the car guide rail, and the first fastener 132 is kept in the tightened state. Then the upper and lower sills are sequentially installed at the first surface 126 and the second surface 128 of the positioning arm 120 of the installation tool 100.

[0049] Because the length of the positioning arm 120 extending from the fixing member 110 to the upper and lower sills represents the distance between the upper and lower sills and the car guide rail, the fact that the positioning arm 120 can no longer move relative to the fixing member 110 means that the distance between the upper and lower sills and the car guide rail remains constant, thereby ensuring that the installation positions of the upper and lower sills in each of the other landings are kept aligned with the installation positions of the upper and lower sills in the first landing. Because the installation positions of the upper and lower sills in the first landing have already been ensured to be accurate by the plumb line or laser, the installation positions of the upper and lower sills in the subsequent landings are also accurate, and there is no need to use the plumb line or laser again during the installation of the upper and lower sills in the subsequent landings, nor is there a need to measure the corresponding distances, thereby greatly simplifying the installation process.

[0050] The various exemplary embodiments of the present application are described in detail herein with reference to the preferred embodiments, however, it should be understood by those skilled in the art that various modifications and changes can be made to the above-described specific embodiments, and various technical features and structures proposed by the present application can be combined, without departing from the concept of the present application, and without exceeding the scope of the present application, the scope of protection of the present application is determined by the appended claims.
