Description

Technical Field

[0001] This invention relates to the field of elevators, and in particular to a handrail head structure, assembly method, and escalator for use in escalators. Background Technology

[0002] Escalators and moving walkways are widely used in large shopping malls, airports, and train stations. Subways and train stations are currently under construction throughout China. Escalators used in high-traffic public transportation situations are generally referred to as heavy-duty public transportation escalators. These escalators typically have a swivel wheel structure at the end of the handrail belt to guide its smooth movement. This swivel section generally experiences significant stress and plays a crucial role in guiding the handrail belt; therefore, the assembly precision of the swivel wheel is critical.

[0003] However, in the existing technology, the slewing wheel is basically an independent device fixed on the support. Especially when it drives the handrail belt to rotate, its stability is low, which is not conducive to the safe operation of the escalator. Summary of the Invention

[0004] To address the problems of existing technologies, this invention provides a handrail head structure, assembly method, and escalator for escalators, improving the assembly stability of the swivel wheel. The technical solution is as follows:

The handrail head structures are respectively located at the upper horizontal section and the lower horizontal section of the escalator. Each handrail head structure includes a swivel wheel mechanism for guiding the handrail and a support mechanism for limiting the swivel wheel mechanism. The support mechanism includes a connecting part, an adjusting beam, and a supporting vertical beam. The supporting vertical beam is fixedly connected to a truss. The adjusting beam is fixedly connected to the supporting vertical beam. The connecting part is fixedly connected to the adjusting beam. The connecting part is used to fixally connect to the swivel wheel mechanism. The support mechanism restricts the movement of the swivel wheel mechanism in the front-back, left-right, up-down, and rotational directions.

[0006] Furthermore, the adjusting beam is provided with a first adjusting bolt, a second adjusting bolt, and a third adjusting bolt. The first adjusting bolt restricts the movement of the adjusting beam in the up-down and left-right directions, the second adjusting bolt restricts the movement of the adjusting beam in the rotation direction, and the third adjusting bolt restricts the movement of the adjusting beam in the front-back direction.

[0007] Furthermore, there are two second adjusting bolts, which respectively mate with the bolt holes on the extensions on both sides of the supporting vertical beam. One second adjusting bolt abuts upward against the adjusting crossbeam, and the other second adjusting bolt abuts downward against the adjusting crossbeam.

[0008] Furthermore, there are multiple first adjusting bolts and one third adjusting bolt. The first adjusting bolts are located on the front of the adjusting beam and the supporting vertical beam, and the third adjusting bolts are located on the side of the adjusting beam and the supporting vertical beam.

[0009] Furthermore, the lower end of the supporting vertical beam is provided with a fixed base plate, and the fixed base plate is provided with a fourth adjusting bolt and a first fastening bolt. The fourth adjusting bolt adjusts the horizontal position of the supporting vertical beam, and the supporting vertical beam is fixedly connected to the truss at the adjusted horizontal position by the first fastening bolt.

[0010] Furthermore, the adjusting crossbeam and the supporting vertical beam are also positioned by locating pins.

[0011] Furthermore, both the fixed base plate and the supporting vertical beam are cuboids, and the supporting vertical beam is vertically fixed to the center of the fixed base plate. The number of the first fastening bolts is four, and they are respectively set at the four corners of the fixed base plate.

[0012] Furthermore, a second fastening bolt is provided on the connecting part, and the support mechanism is fixedly connected to the rotary wheel mechanism through the second fastening bolt.

[0013] On the other hand, the present invention also provides a method for assembling an armrest head structure, comprising:

[0014] The position of the rotary wheel mechanism is determined by tooling.

[0015] Assemble the adjusting beam and supporting vertical beam according to the positioning of the rotary wheel mechanism;

[0016] Tighten the first adjusting bolt, the second adjusting bolt, the third adjusting bolt on the adjusting beam and the fourth adjusting bolt on the supporting vertical beam;

[0017] Secure the first fastening bolt on the support beam and the second fastening bolt on the connecting part;

[0018] Install positioning pins on the adjusting beam and supporting vertical beam.

[0019] In another aspect, the present invention provides an escalator, including an elevator body and a handrail, the handrail including the handrail head structure for heavy-duty escalators as described above.

[0020] The beneficial effects of the technical solution provided by this invention are as follows:

[0021] a. Simple structure, sufficient strength, and good stability;

[0022] b. The armrest head structure is easy and quick to adjust during assembly;

[0034] In one embodiment of the present invention, a handrail head structure for a heavy-duty escalator is provided, see [link to relevant documentation]. Figure 5 The handrail head structure 5 is respectively located at the upper horizontal section and the lower horizontal section of the escalator, such as... Figure 1 and Figure 2 As shown, each handrail head structure 5 includes a rotating wheel mechanism 1 for guiding the handrail belt and a support mechanism 2 for limiting the rotating wheel mechanism 1. The support mechanism 2 includes a connecting part 21, an adjusting crossbeam 22, and a supporting vertical beam 23, as shown. Figure 3 As shown, the supporting vertical beam 23 is fixedly connected to the truss 3, the adjusting horizontal beam 22 is fixedly connected to the supporting vertical beam 23, the connecting part 21 is fixedly connected to the adjusting horizontal beam 22, and the connecting part 21 is used to fixally connect to the rotary wheel mechanism 1. The adjusting horizontal beam 22 is connected to the rotary wheel mechanism 1, and the supporting vertical beam 23 is used to support the entire handrail head structure 5. The supporting mechanism 2 restricts the movement of the rotary wheel mechanism 1 in the front-back, left-right, up-down, and rotational directions. The rotary wheel mechanism 1 is used to guide the handrail belt, and to ensure the smooth splicing of the supporting mechanism 2, it is necessary to adjust and limit the six degrees of freedom (up-down, left-right, front-back) and even the angular rotation of the supporting mechanism 2.

[0035] The supporting vertical beam 23 is fixedly connected to the truss 3 as follows: A fixed base plate 232 is provided at the lower end of the supporting vertical beam 23. A fourth adjusting bolt 233 and a first fastening bolt 234 are provided on the fixed base plate 232. The fourth adjusting bolt 233 adjusts the horizontal position of the supporting vertical beam 23. The supporting vertical beam 23 is then fixedly connected to the truss 3 at the adjusted horizontal position via the first fastening bolts 234. Preferably, both the fixed base plate 232 and the supporting vertical beam 23 are cuboids. The supporting vertical beam 23 is vertically fixed to the center of the fixed base plate 232. Four first fastening bolts 234 are provided, respectively located at the four corners of the fixed base plate 232.

[0036] See Figure 3 and Figure 4 The adjusting beam 22 is provided with a first adjusting bolt 221, a second adjusting bolt 222 and a third adjusting bolt 223. The first adjusting bolt 221 restricts the movement of the adjusting beam 22 in the up-down and left-right directions, the second adjusting bolt 222 restricts the movement of the adjusting beam 22 in the rotation direction, and the third adjusting bolt 223 restricts the movement of the adjusting beam 22 in the front-back direction. The connecting part 21 is provided with a second fastening bolt 211, and the support mechanism 2 is fixedly connected to the rotary wheel mechanism 1 through the second fastening bolt 211.

[0037] like Figure 3 As shown, there are two second adjusting bolts 222, which respectively mate with the bolt holes on the extensions 231 on both sides of the supporting vertical beam 23. One second adjusting bolt 222 abuts upward against the adjusting crossbeam 22 (located at the lower end), and the other second adjusting bolt 222 abuts downward against the adjusting crossbeam 22 (located at the upper end).

[0038] Preferably, the number of the first adjusting bolts 221 is multiple (e.g., ...). Figure 3 (As shown in four), the number of the third adjusting bolts 223 is one. The first adjusting bolts 221 are provided on the front of the adjusting beam 22 and the supporting vertical beam 23, and the third adjusting bolts 223 are provided on the side of the adjusting beam 22 and the supporting vertical beam 23, so that the adjusting beam 22 is restricted in the rotation direction by the supporting vertical beam 23.

[0039] Finally, the adjusting beam 22 and the supporting vertical beam 23 are also positioned by the positioning pin 4.

[0040] In one embodiment of the present invention, a method for assembling an armrest head structure is also provided, comprising the following steps, see below. Figure 6 :

[0044] S4. Secure the first fastening bolt on the support beam and the second fastening bolt on the connecting part;

[0045] S5. Install positioning pins on the adjusting beam and supporting vertical beam.

[0046] Specifically, for the head rotating wheel mechanism 1, the support mechanism 2 is adjusted and positioned in the up, down, left, right, forward, backward, and even rotation direction. After positioning, the support mechanism 2 limits the rotating wheel mechanism 1 in various directions to ensure that the rotating wheel mechanism 1 can correctly guide the handrail belt.

[0047] In one embodiment of the present invention, an escalator is provided, such as Figure 5 As shown, it includes an elevator body and a handrail, the handrail including the handrail head structure for heavy-duty escalators as described above.

[0048] This invention addresses the issue of the head rotating wheel by adjusting the support mechanism up, down, left, right, forward, backward, and even rotation. After adjustment, the support mechanism is positioned to limit the rotation wheel mechanism, ensuring that the rotating wheel can correctly guide the handrail belt.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
