[0003] Roller guide shoes are elevator accessories primarily used to reduce friction between the guide rails and the guide shoes, saving energy and improving passenger comfort. The roller guide shoes are equipped with rollers that engage with the guide rails, allowing the car to move up and down along those rails. Typically, each elevator car has four sets of guide shoes installed, located on both sides of the upper beam and below the safety clamp seat at the bottom of the car.

[0004] As the elevator market develops, the requirements for the cost of roller guide shoes are becoming increasingly stringent. Existing roller guide shoe products are generally inconvenient to install, and are also costly and heavy. Simply cutting holes in the material to reduce its weight would affect the structural strength of the material.

[0032] Please see Figure 1-3 This embodiment provides an elevator roller guide shoe, which includes:

[0033] The base plate 1 has a top surface and a bottom surface that are disposed opposite to each other, and the edge of the base plate 1 has a connecting mechanism 11 that flips up from the bottom surface to the top surface of the base plate;

[0034] Vertical beam 2 is installed on the top surface of base plate 1. At least part of the bottom edge of vertical beam 2 is welded to the connecting mechanism 11. Rollers are installed on vertical beam 2 for contacting the guide rail in elevator shaft.

[0035] The intermediate plate 3 is installed on the top surface of the base plate 1. At least part of the bottom edge of the intermediate plate 3 is welded to the connecting part 11. The intermediate plate 3 abuts against the side wall of the vertical beam 2 away from the roller.

[0036] Based on the structure described in this embodiment, during installation, as follows: Figure 1As shown, the base plate 1 has multiple insertion holes at corresponding positions, and the bottom of the vertical beam 2 and the intermediate plate 3 have multiple downward protruding slots that match them. The vertical beam 2 and the intermediate plate 3 can be conveniently pre-installed on the corresponding positions of the base plate 1. Specifically, the pre-installed vertical beam 2 and the intermediate plate 3 are in contact with each other. In this embodiment, the entire side wall of the intermediate plate 3 facing the base plate 1 is in contact with the wall of the vertical beam 2. At the same time, at least part of the bottom position of the vertical beam 2 is attached to the connecting mechanism 11, and at least part of the bottom position of the intermediate plate 3 is also attached to the connecting mechanism 11. The operator can weld the parts that are attached to the connecting mechanism 11 so that the vertical beam 2 and the intermediate plate 3 are completely fixed to the base plate 1.

[0037] The above-mentioned flange treatment of the base plate 1 forms a raised connecting mechanism 11. Specifically, during welding, the position where the vertical beam 2 and the intermediate plate 3 contact the connecting mechanism 11 can be treated, or the position where the vertical beam 2 and the intermediate plate 3 contact the top surface of the base plate 1 can be welded directly to form a strong connection.

[0038] In the above embodiments, a hinged connecting mechanism 11 can be provided on the base plate 1 for welding the vertical beam 2 and the intermediate plate 3, resulting in high strength and easy connection and installation. Specifically, the base plate 1 can be formed by bending an integral flat plate upwards to form the connecting mechanism 11. During installation, the connecting mechanism 11 is welded to the corresponding positions of the vertical beam 2 and the bottom of the intermediate plate 3 to form a tight and fixed connection. At the same time, the connecting mechanism 11 also has a reinforcing effect, making the base plate 1 stronger and less prone to deformation from the edge. In this utility model, the intermediate plate 3 supports the vertical beam 2 from one side, and the simple triangular structure achieves a strong vertical positioning effect for the base plate 1, which is low in cost and easy to install.

[0039] In this embodiment, the base plate 1 can be connected to a tray fixed on the elevator car, and the rollers with a certain buffering effect installed on the vertical beam 2 contact the guide rails in the elevator shaft, so that the car and the guide rails form a flexible connection with the elevator roller guide shoes. The rollers themselves can also be combined with structures such as rocker arms to achieve a greater buffering effect in the direction perpendicular to the elevator movement.

[0040] The vertical beam 2 extends along the direction of the guide rail. The length of the vertical beam 2 should be at least greater than the diameter of the roller itself, so that the vertical beam 2 can completely cover the roller in the vertical direction, and in some cases, it can protect the roller in both the upper and lower directions.

[0041] Further, please see Figure 3The rollers include a first roller group 21 and a second roller group 22, which are arranged parallel to each other in the horizontal direction. A gap exists between the first roller group 21 and the second roller group 22 to clamp the guide rail in the elevator shaft. Specifically, during elevator operation, the guide rail is clamped in the gap between the first roller group 21 and the second roller group 22. The first roller group 21 and the second roller group 22 rotate synchronously and are displaced relative to the guide rail, which allows the guide rail to be clamped tightly and maintains relative stability between the elevator roller guide shoes and the guide rail.

[0042] Further, please see Figure 1 , 2 The connecting mechanism 11 includes a first connecting part 111, a second connecting part 112, and a third connecting part 113. The first connecting part 111 is located on the side of the base plate 1 closest to the first wheel assembly 21 and is welded to the vertical beam 2. The second connecting part 112 is located on the side of the base plate 1 closest to the second wheel assembly 22 and is welded to the vertical beam 2. The third connecting part 113 is located on the side of the base plate 1 furthest from the vertical beam 2 and is welded to the intermediate plate 3. In this embodiment, the base plate 1 is set as an approximately regular rectangle. The first connecting part 111 and the second connecting part 112 are set as two symmetrical sides of the rectangle, which clamp and connect the vertical beam 2 from the left and right directions in the figure, maximizing the balance and stability of the connection to the vertical beam 2. The third connecting part 113 is a rectangular side located between the first connecting part 111 and the second connecting part 112, adjacent to the intermediate plate 3 and away from the first wheel assembly 21 and the second wheel assembly 22. It is mainly used to provide support and fixation for the edge of the intermediate plate 3.

[0043] Of course, the first connecting part 111, the second connecting part 112 and the third connecting part 113 mentioned above can be set as separate flanges that are not connected to each other. Before processing, the base plate 1 can be set as an approximate hexagon, so that during installation, the corresponding first connecting part 111, the second connecting part 112 and the third connecting part 113 can be flipped up directly without interfering with each other, making it easy to process and finally forming a rectangular structure.

[0044] Please see Figure 3 The elevator roller guide shoe also includes a cover 4, which is installed on the top of the vertical beam 2. The projection of the cover 4 in the horizontal direction covers at least all the rollers. The cover 4 has a notch 41 for accommodating the guide rail passing through the elevator shaft. The side of the cover 4 with the notch 41 has a bend 42 that bends from the top surface of the cover 4 towards the bottom surface. The side of the cover 4 away from the notch 41 has an angle 43. In the above structure, the notch 41 is formed by direct machining. Its main purpose is to shield and protect the first roller group 21 and the second roller group 22 at the bottom position as much as possible without reducing the size of the cover 4, while only allowing the guide rail to pass through.

[0045] Because of the notch 41, the strength of the corresponding side of the cover 4 is reduced. Therefore, by using the same folded bending part 42, the strength of the corresponding side of the cover 4 can be compensated, and deformation of the side of the cover 4 with the notch 41 can be avoided.

[0046] For the edge without the notch 41, the material can be reduced to form the chamfer 43, thereby reducing the weight of the cover 4 itself and indirectly reducing the material cost, thus achieving the cost and weight reduction advantages of this utility model.
