Description

Technical Field

[0001] The utility model relates to the technical field of elevator disassembly tools, in particular to an escalator pedal wheel disassembly tool. Background Art

[0002] The step wheels of escalators are consumable parts that require frequent replacement and require the use of suitable step wheel removal tools. Existing techniques using a conventional three-jaw puller for removal can cause deformation of the rubber wheel, which can cause the wheel and bearing to fall off, making it impossible to remove the step wheel all at once. Furthermore, using a tray-type bearing removal method, the base plate cannot be inserted into the step wheel due to the thickness limit between the step wheel and the step seat.

[0003] Chinese utility model patent publication number CN210968711U discloses a tool for disassembling the step wheel of an escalator. The tool clamps the bearing in the step wheel with a load-bearing pad, making it difficult for the bearing and the rubber wheel to separate during the disassembly process. However, the tool has many parts and is cumbersome to use. In addition, the gap between the step wheel and the step seat is small, making it difficult to operate. Utility Model Content

[0022] The present invention will be described in further detail below with reference to the accompanying drawings.

[0023] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0024] Example 1:

[0025] like Figure 1 and Figure 2 As shown, a tool for removing escalator pedal wheels includes: a fixing sleeve 1 and a push rod 2. The fixing sleeve 1 has a fixing cavity 104 for accommodating the wheel and an opening 105 for the wheel to enter the fixing cavity 104. The push rod 2 is screwed to one end of the fixing sleeve 1 and extends into the fixing cavity 104.

[0026] The fixing sleeve 1 includes a top plate 101, a support plate 102 and a side guard plate 103. The top plate 101 and the support plate 102 are respectively arranged on the front and rear sides of the fixing cavity 104. The side guard plate 103 is connected between the top plate 101 and the support plate 102. A fixing cavity 104 is formed between the side guard plate 103, the top plate 101 and the support plate 102, and an opening 105 is formed between the two ends of the side guard plate 103.

[0027] In this embodiment, the side guard plates 103 , the top plate 101 and the supporting plate 102 are an integrated structure, and the side guard plates 103 are arc-shaped.

[0028] A threaded hole 106 is provided on the top plate 101 , and the threaded hole 106 passes through the inside and outside of the fixing cavity 104 . The top rod 2 is screwed into the threaded hole 106 and is perpendicular to the supporting plate 102 .

[0029] The side guard plate 103 is provided with a handle 3, which is provided on a side opposite to the opening 105. The handle 3 is fixed to the side guard plate 103 in a screw connection or is integrally connected to the side guard plate 103.

[0030] A through slot 107 is provided on the supporting plate 102 , and the through slot 107 radially extends from the opening 105 to the center of the supporting plate 102 .

[0031] In this embodiment, the through slot 107 is a slot of uniform width, and the inner end of the through slot 107 is an arc-shaped end 108, the arc center of the arc-shaped end 108 being coaxial with the threaded hole 106. During disassembly, the axle of the wheel 5 is located within the arc-shaped end 108 and coaxial with the axle, which facilitates positioning of the wheel 5 and ensures that the push rod 2 can support the axle.

[0032] Guide slopes 109 are provided on both sides of the outer end of the through slot 107 . The two guide slopes 109 form a flared structure at the end of the through slot 107 . The flared structure facilitates the axle of the wheel 5 to enter the through slot 107 .

[0033] like Figure 3As shown, during disassembly, the opening 105 of the fixing sleeve 1 is directed toward the wheel 5 and gradually approached to the wheel 5, so that the axle of the wheel 5 enters the through groove 107 and the wheel 5 enters the fixing cavity 104; when the axle of the wheel 5 and the push rod 2 are located on the same axis, the push rod 2 is driven to rotate and gradually extend into the fixing cavity 104 through an electric or pneumatic tool, and the push rod 2 resists the reverse force of the wheel axle to drive the wheel 5 out, completing the disassembly of the wheel 5.

[0034] Example 2:

[0035] like Figure 4 As shown, the difference from Example 1 is that the through groove 107 is a V-shaped groove, that is, the width of the through groove 107 gradually increases from the center to the outside, which facilitates the axle of the wheel 5 to smoothly enter the through groove 107 during the disassembly process.

[0036] Example 3:

[0037] like Figure 5 As shown, the difference from Examples 1 and 2 is that the side guard plate 103 is in the shape of a U-shaped structure, and the corresponding top plate 101 and support plate 102 can be rectangular plates. When disassembling, the three sides of the side guard plate 103 are used to support the wheel 5, making it convenient for the top rod 2 to align with the axle of the wheel 5.
