Description

Technical Field

[0001] This utility model belongs to the field of elevator car frames, and in particular relates to an elevator car frame that is easy to install guide shoes. Background Technology

[0002] The elevator car frame is where the elevator car is installed. The traction machine drives the car to rise and fall through the car frame. To ensure smooth car movement and reduce swaying, two guide shoes are installed on both sides of the car frame in the width direction. The guide shoes slide on the guide rails on the shaft wall and are bolted to the car frame. When fixing the guide shoes to the car frame, it is necessary to ensure that the relative position between the guide shoes and the guide rails is accurate, and that the gaps between the guide shoes and the guide rails on both sides are as equal as possible, generally 0.5 to 1 mm, to reduce wear on the guide shoes. Adjust the horizontal position of the guide shoes on the car frame according to the position of the guide rails, and finally tighten the bolts used to fix the guide shoes.

[0003] In actual engineering cases, it has been found that because the guide shoe is fixed between the car frame and the guide rail, the space for observing the gap between the guide rail and the guide shoe is narrow, making it difficult to adjust the position of the guide shoe. The installation of the guide shoe may require several adjustments, making the installation quite difficult. Utility Model Content

[0004] The purpose of this invention is to provide an elevator car frame that is easy to install guide shoes. This invention has the advantage of convenient guide shoe installation.

[0005] The technical solution of this utility model is as follows: an elevator car frame that is easy to install guide shoes. The elevator car frame is provided with at least upper and lower positioning modules on both sides. The positioning module includes a base plate connected to the car frame. The base plate is provided with positioning holes that match the shape of the guide shoes. Positioning blocks connected to the base plate are provided on the upper and lower sides of the positioning holes. Positioning grooves are provided on the positioning blocks. The width of the positioning grooves matches the guiding part of the guide rail.

[0006] In the aforementioned elevator car frame that is easy to install guide shoes, the base plate is a sheet metal part, the positioning block is a plastic part, the upper and lower ends of the base plate are provided with insertion holes, and the bottom sides of the positioning block are provided with slots that mate with the insertion holes.

[0007] In the aforementioned elevator car frame that is easy to install guide shoes, the horizontal sides of the base plate are stamped and bent to form mounting parts, and the mounting parts are provided with mounting holes.

[0008] In the aforementioned elevator car frame that is easy to install guide shoes, positioning plates are formed on both sides of the positioning groove. The cross-section of the positioning plate is a right trapezoid, and the thickness at the root of the positioning plate is greater than the thickness at the end of the positioning plate.

[0009] In the aforementioned elevator car frame that is easy to install guide shoes, multiple vertical through slots are provided on both sides of the positioning slot.

[0010] Compared with existing technologies, this utility model adds a positioning module to the existing car frame. The positioning module has two positioning blocks, one upper and one lower, with positioning grooves on each block. After inserting the guide portion of the guide rail into the positioning groove, the positioning module is fixed in position on the car frame. Removing the positioning blocks from the positioning module and placing the guide shoe into the positioning hole ensures that the gaps between the guide rail and the guide shoe are approximately equal, thus fixing the guide shoe on the car frame in one step without repeated adjustments, making installation convenient. Therefore, this utility model has the advantage of convenient guide shoe installation.

[0011] Furthermore, through further structural optimization, the positioning block is inserted into the base plate, and the positioning block can be recycled, reducing costs; multiple through slots are provided on both sides of the positioning groove to reduce the contact area between the positioning block and the guide rail, reduce the friction between the positioning block and the guide rail, and make it easier to recycle the positioning block.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0019] Example: An elevator car frame that is easy to install guide shoes, such as Figure 1 As shown, at least one upper and lower positioning module 1 is provided on both sides of the elevator car frame.

[0020] The positioning module 1 includes a sheet metal base plate 2, with a positioning hole 4 in the center that matches the shape of the guide shoe 3. The horizontal sides of the base plate 2 are stamped and bent to form mounting parts 10, and mounting parts 10 are provided with mounting holes 11. The base plate 2 is fixed to the car frame by screws passing through the mounting holes 11.

[0021] The base plate 2 has a socket 8 at both the top and bottom. A nylon positioning block 5 is provided inside the socket 8. The bottom sides of the positioning block 5 are provided with slots 9 that cooperate with the socket 8. The positioning block 5 and the base plate 2 are slightly fitted together.

[0022] The positioning block 5 has a vertical positioning groove 6. The width of the positioning groove 6 matches the guiding part of the guide rail 7, and a transition fit can be used. A small amount of lubricating oil can be applied to the two side walls of the positioning groove 6 to reduce the friction between the positioning block 5 and the guide rail. Positioning plates 12 are formed on both sides of the positioning groove 6. The cross-section of the positioning plate 12 is a right trapezoid, and the thickness at the root of the positioning plate 12 is greater than the thickness at the end of the positioning plate 12. Multiple vertical through slots 13 are provided on both sides of the positioning groove 6.

[0023] Instructions for use: Before installing the guide shoe 3, first install the positioning module 1 onto the car frame. Specifically, insert the guide part of the guide rail 7 into the positioning slots 6 of the upper and lower positioning blocks 5, and use screws to fix the positioning module 1 to the car frame through the mounting holes 11. Pull the positioning blocks 5 up or down; the pulled-out positioning blocks 5 can be recycled. Place the guide shoe 3 into the positioning hole 4. At this point, the gaps between the guide rail 7 and the guide shoe 3 on both sides are approximately equal. Use bolts to fix the guide shoe 3 to the car frame.

[0024] The mounting portion 10 is formed by stamping and bending on both horizontal sides of the base plate 2. This is to prevent the positioning block 5 from being pressed tightly after the base plate 2 is installed on the car frame, and to facilitate the removal and recycling of the positioning block 5.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
