Description

Technical Field

[0001] The utility model belongs to the technical field of escalators and relates to an improved escalator structure. Background Art

[0002] like Figure 1 — Figure 2 As shown, the handrail 500 is an important structure of the escalator. In order to ensure that the handrail 500 can circulate, people often set a mounting plate 600 inside the escalator to guide the movement of the handrail 500. Specifically, it is necessary to set a first guide wheel 610 and a first traction wheel 620 on the mounting plate 600. The handrail 500 inside the escalator is located between the first guide wheel 610 and the first traction wheel 620. The first traction wheel 620 can prevent the handrail 500 from moving out of position, and the first guide wheel 610 can support the handrail 500 to prevent To prevent the handrail 500 from collapsing, people often use multiple mounting plates 600 to arrange them at intervals during production, and install a first guide wheel 610 and a first traction wheel 620 on each mounting plate 600 to form a set. After experiments and tests, the handrail 500 between three adjacent mounting plates 600 can move stably under the support of the first guide wheels 610 at the left and right ends. Therefore, there is no need to set the first guide wheel 610 in the middle. This will lead to excessive use of the first guide wheel 610, which increases the production cost of the escalator. Summary of the Invention

[0003] The purpose of the utility model is to solve the above problems in the existing technology and to propose an improved escalator structure which can reduce the usage of the first guide wheel and reduce the cost of use.

[0004] The purpose of the utility model can be achieved through the following technical solutions: an improved escalator structure, comprising:

[0005] A truss, wherein a plurality of top plates are provided on the top of the truss, a plurality of support plates are provided on the inner side surface of the truss, a second guide wheel is provided on the top of the support plate, a guide plate is provided on the top plate, and a second traction wheel is provided on the guide plate.

[0006] In the above-mentioned improved escalator structure, a guide rod for mounting a second traction wheel is provided on the guide plate, and the plurality of second guide wheels and the plurality of second traction wheels are located on the same vertical plane.

[0007] In the above-mentioned improved escalator structure, the top of the support plate is provided with connecting bolts for mounting the second guide wheel.

[0008] In the above-mentioned improved escalator structure, a receiving groove is provided on the top of the support plate.

[0009] In the above-mentioned improved escalator structure, a second clamping plate is installed on the top plate, and a handrail plate is detachably connected to the second clamping plate.

[0010] In the above-mentioned improved escalator structure, a second clamping groove for mounting a handrail is provided on the second clamping plate, and a fastener for clamping the handrail is provided on the second clamping plate.

[0011] In the above-mentioned improved escalator structure, the fastener includes a pressing bolt threadedly connected to the second clamping plate, and a pressing plate is provided in the second clamping groove.

[0012] In the above-mentioned improved escalator structure, there is a squeezing force between the pressing plate and the handrail plate.

[0013] In the above-mentioned improved escalator structure, a support plate is provided on the inner wall of the second slot, and the pressure plate and the support plate are respectively located on both sides of the handrail plate.

[0014] In the above-mentioned improved escalator structure, there is a squeezing force between the abutment plate and the handrail plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, the second traction wheel and the second guide wheel are separately arranged, and are not arranged as an integral whole. Thus, when installing the escalator, people can arrange a second traction wheel directly above a second guide wheel, and assemble the escalator in the form of another second traction wheel between the two second guide wheels, thereby effectively reducing the use of the second guide wheels and further effectively reducing the cost of the escalator.

In the present utility model, a receiving groove is provided on the top of the support plate. Therefore, the collapsed inner handrail will fall into the receiving groove, but the inner handrail will never contact the bottom of the receiving groove. In this way, it can be ensured that the inner handrail can move stably inside the escalator. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0023] like Figure 3 — Figure 4 As shown, the improved escalator structure of the present invention includes a truss 100 , a top plate 110 , a support plate 200 , a second guide wheel 210 , a guide plate 111 and a second traction wheel 112 .

[0024] In the present invention, the handrail located outside the escalator is called the outer handrail 300, and the handrail located inside the escalator is called the inner handrail 400. During operation, when the outer handrail 300 passes around the end of the escalator and enters the interior of the escalator, the outer handrail 300 will be transformed into the inner handrail 400. Similarly, when the inner handrail 400 passes around the end of the escalator and is exposed outside the escalator, the inner handrail 400 will be transformed into the outer handrail 300.

[0025] A plurality of top plates 110 are provided on the top of the truss 100, a plurality of support plates 200 are provided on the inner side surface of the truss 100, a second guide wheel 210 is provided on the top of the support plate 200, a guide plate 111 is provided on the top plate 110, a second traction wheel 112 is provided on the guide plate 111, and the inner handrail belt 400 is located between the second traction wheel 112 and the second guide wheel 210. When working, the second guide wheel 210 supports the inner handrail belt 400, and the second traction wheel 112 can prevent the inner handrail belt 400 from moving out of position, that is, the inner handrail belt 400 can move in a direction along the tracks of the plurality of second traction wheels 112; In a further step, since the second guide wheel 210 is directly provided on the support plate 200, and the second traction wheel 112 is installed on the support plate 200 through the guide plate 111 and the top plate 110, the second traction wheel 112 and the second guide wheel 210 are provided separately and are not provided as a whole. In this way, when people install the escalator, they can arrange a second traction wheel 112 directly above a second guide wheel 210, and assemble the escalator in the form of another second traction wheel 112 spaced between the two second guide wheels 210, thereby effectively reducing the use of the second guide wheel 210 and thus effectively reducing the cost of the escalator.

[0026] When the second guide wheel 210 is not provided on the support plate 200 and a second traction wheel 112 is provided above the support plate 200, the inner handrail belt 400 here will collapse toward the support plate 200 due to its own gravity. In the present utility model, a receiving groove 230 is provided on the top of the support plate 200. Therefore, the collapsed inner handrail belt 400 will fall into the receiving groove 230, but the inner handrail belt 400 will not contact the bottom of the receiving groove 230 from beginning to end. In this way, it can be ensured that the inner handrail belt 400 can move stably inside the escalator.

[0027] The guide plate 111 is provided with a guide rod 113 for installing the second traction wheel 112, and the top of the support plate 200 is provided with a connecting bolt 220 for installing the second guide wheel 210. During installation, people need to thread the guide rod 113 on the guide plate 111 and clamp it with a nut. Thereafter, the second guide wheel 210 is installed on the support plate 200 through the connecting bolt 220, and multiple second guide wheels 210 and multiple second traction wheels 112 are located on the same vertical plane. In this way, after people install the inner handrail belt 400 between the multiple second guide wheels 210 and the multiple second traction wheels 112, the second traction wheel 112 will limit the misalignment movement of the inner handrail belt 400. At the same time, the second guide wheel 210 can support the inner handrail belt 400 and prevent the inner handrail belt 400 from contacting the bottom of the accommodating groove 230.

[0028] A second clamping plate 120 is installed on the top plate 110, and an armrest plate 121 is detachably connected to the second clamping plate 120. A second clamping slot 122 for installing the armrest plate 121 is provided on the second clamping plate 120, and a fastener 123 for clamping the armrest plate 121 is provided on the second clamping plate 120. The above-mentioned outer armrest belt 300 is movably installed on the top of the armrest plate 121. During installation, people need to clamp the bottom of the armrest plate 121 into the second clamping slot 122 of the second clamping plate 120, and then use the fastener 123 to strengthen the connection strength between the armrest plate 121 and the second clamping plate 120, so that the outer armrest belt 300 can move stably on the armrest plate 121.

[0029] The fastener 123 includes a pressing bolt 1231 threadedly connected to the second clamping plate 120, a pressing plate 1232 is provided in the second clamping groove 122, and a push plate 124 is provided on the inner wall of the second clamping groove 122, and the pressing plate 1232 and the push plate 124 are respectively located on both sides of the armrest plate 121. When people insert the bottom of the armrest plate 121 into the second clamping groove 122, they need to screw the pressing bolt 1231 to press the pressing plate 1232 and the armrest plate 121 on the push plate 124, that is, there is an extrusion force between the push plate 124 and the armrest plate 121, and there is an extrusion force between the pressing plate 1232 and the armrest plate 121. In this way, the pressing plate 1232 and the push plate 124 can clamp the armrest plate 121, thereby effectively improving the connection strength between the armrest plate 121 and the top plate 110, thereby ensuring that the outer armrest belt 300 can move stably on the armrest plate 121.
