Description

Technical Field

[0001] The invention relates to the technical field of escalators, in particular to an escalator unloading rail adjusting device. Background Art

[0002] With the improvement of public transportation facilities, particularly the large-scale development of urban rail transit, represented by subways, heavy-duty escalators are being produced and used in large quantities. Heavy-duty escalators currently on the market are generally equipped with unloading rails to relieve the pressure of the step chain on the guide rails in the transition area between the upper and lower steps. To ensure that the unloading rails can achieve this function, they must be adjusted properly. Currently, unloading rails are installed using a tape measure, which can result in large installation errors, making installation quality difficult to control and time-consuming and labor-intensive. Summary of the Invention

[0003] In view of this, in order to solve the problems of the prior art, the present invention provides an improved escalator unloading rail adjustment device, which is installed on the guide rail of the escalator to assist in adjusting the installation position of the unloading rail so that it is installed in place for normal operation.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] An escalator unloading rail adjustment device includes a mounting plate, an adjusting member and a fixed plate. The bottom surface of one end of the mounting plate is fixedly connected to the top surface of the adjusting member. The fixed plate is slidably connected to the side surface of the mounting plate. The mounting plate includes a positioning portion and a positioning groove opened along its height direction. The positioning groove and the fixed plate are used to fix the unloading rail. The positioning portion and the adjusting member are used to fix the guide rail of the escalator.

[0006] Through the cooperation of the fixing plate and the positioning groove, as well as the cooperation of the positioning part and the adjusting piece, the height of the fixing plate is adjusted and fixed according to the height of the unloading rail and the guide rail of different types of escalators. The unloading rail can be installed in place by directly contacting the top surface of the unloading rail with the bottom surface of the fixing plate, avoiding installation errors.

[0007] According to some preferred embodiments of the present invention, the bottom surface of the mounting plate includes a first positioning surface, the positioning portion includes a second positioning surface and a protrusion located at an end of the second positioning surface away from the first positioning surface; the distance from the second positioning surface to the top surface of the mounting plate is greater than the distance from the first positioning surface to the top surface of the mounting plate, and is less than the distance from the bottom surface of the protrusion to the top surface of the mounting plate.

[0008] According to some preferred embodiments of the present invention, the adjusting member includes a fixing block and at least one first bolt rotatably connected to the fixing block, wherein the first bolt is configured to abut against a side of the guide rail away from the fixing plate. In some embodiments of the present invention, the fixing block is provided with screw holes extending across its width, with the number of screw holes being the same as the number of first bolts, and each first bolt being rotatably connected to a corresponding screw hole. The first bolt is rotated in the screw hole until the end of the first bolt abuts against the side of the guide rail, thereby tightening against it and thereby securing the guide rail.

[0009] According to some preferred embodiments of the present invention, the first positioning surface is connected to the top surface of the fixed block, the width of the fixed block is smaller than the length of the first positioning surface, and the length of the first bolt is larger than the length of the first positioning surface; so that a distance is left between the fixed block and the guide rail, and the first bolt has an effective adjustable length in the fixed block, and the length of the first bolt screwed in and out can be adjusted according to the size of different types of escalators. The horizontal distance between the side of the protrusion close to the second positioning surface and the positioning groove is equal to the distance between the unloading rail and the guide rail. This ensures that there is a certain distance between the guide rail and the unloading rail, eliminating the need for back and forth switching, simplifying the operation, and facilitating the adjustment of the unloading rail into place.

[0010] According to some preferred embodiments of the present invention, the second positioning surface abuts the top surface of the guide rail, the side of the protrusion closest to the second positioning surface abuts the side of the guide rail away from the adjusting member, and the width of the guide rail is greater than the length of the second positioning surface. The second positioning surface and the protrusion limit the top and left sides of the guide rail, and then cooperate with the adjusting member to secure the adjusting device to the guide rail.

[0011] According to some preferred embodiments of the present invention, the centerline of the fixing plate and the centerline of the positioning slot are located in the same vertical direction, the height of the fixing plate is greater than the distance from the top surface of the mounting plate to the positioning slot, and the width of the positioning slot is equal to the width of the unloading rail. By moving the fixing plate up and down along the height direction of the mounting plate, the distance the fixing plate extends out of the positioning slot varies. The height of the fixing plate can be adjusted according to the model or tonnage of the escalator, and then the bottom surface of the fixed fixing plate can be directly abutted against the top surface of the unloading rail to adjust the position. The width of the positioning slot is equal to the width of the unloading rail, which facilitates the adjustment device to fix the unloading rail.

[0012] According to some preferred embodiments of the present invention, the fixing plate includes a first fixing hole and second fixing holes located on both sides of the first fixing hole, and the mounting plate is provided with at least two third fixing holes and two oval holes.

[0013] According to some preferred embodiments of the present invention, the oval holes are provided along the length of the mounting plate, and the second fixing holes are connected to the corresponding oval holes via a second bolt. The third fixing hole and the first fixing hole are located on the same vertical line, and the second fixing hole and the center of the oval holes are located on the same vertical line. The provision of the oval holes facilitates adjustment and installation of the fixing plate. When securing the fixing plate to the mounting plate, the second bolt is inserted through both the second fixing hole and the corresponding oval hole, and the nut is tightened to secure the fixing plate.

[0014] According to some preferred embodiments of the present invention, a stopper is provided, comprising a first portion and a second portion connected to each other, wherein when the second bolt is located between the top and bottom ends of the circular hole, the second portion simultaneously penetrates the first fixing hole and one of the third fixing holes. The stopper is primarily configured to simultaneously penetrate the first fixing hole and one of the third fixing holes to mark the height of the unloading rail corresponding to the tonnage of one escalator. In some embodiments of the present invention, when the second bolt is located at the top and bottom ends of the circular hole, and when the first fixing hole overlaps with two of the third fixing holes, the distance that the fixing plate extends out of the positioning slot is different, corresponding to four situations, i.e., four tonnages of the escalator. In these four situations, the position of the fixing plate is fixed in advance, and then the adjustment device is secured to the guide rail and the adjustment device via the first positioning surface, the positioning portion, and the adjustment member. The unloading rail is then adjusted so that it abuts against the fixing plate, thereby achieving the installation of the unloading rail. In other embodiments of the present invention, the number of third fixing holes is not limited to two, and more third fixing holes can be provided according to actual conditions and the different tonnages of escalators to meet installation requirements.

[0015] According to some preferred embodiments of the present invention, the length of the first portion is greater than the lengths of the first and third fixing holes, and the thickness of the second portion is equal to the heights of the first and third fixing holes, thereby ensuring that the fixing plate can be fixed to the mounting plate when the stopper is inserted into the first and third fixing holes.

[0016] Compared with the prior art, the benefit of the present invention lies in that: the escalator unloading rail adjustment device of the present invention first fixes the adjustment device on the guide rail of the escalator, adjusts the position of the fixing plate on the mounting plate, and then pushes the unloading rail along the positioning groove so that the unloading rail and the fixing plate abut against each other, effectively ensuring that the unloading rail is installed in place, avoiding installation errors, and is simple to operate, ensuring that the unloading rail can function normally.

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0025] Reference Figure 1The adjusting device 10 of this embodiment is installed on the guide rail 30 of the escalator to assist in adjusting the installation position of the unloading rail 20 so that it is installed in place for normal operation. The adjusting device 10 of this embodiment includes a mounting plate 1, an adjusting member 2, a fixing plate 3 and a limit block 4. The bottom surface of one end of the mounting plate 1 is fixedly connected to the top surface of the adjusting member 2, and the fixing plate 3 is slidably connected to the side of the mounting plate 1. Among them, the mounting plate 1 includes a positioning portion and a positioning groove 11 opened along its height direction. The positioning groove 11 and the fixing plate 3 are used to fix the unloading rail 20, and the positioning portion and the adjusting member 2 are used to fix the guide rail 30 of the escalator. Through the cooperation between the fixing plate 3 and the positioning groove 11, and the cooperation between the positioning portion and the adjusting member 2, the height of the fixing plate 3 is adjusted and fixed according to the height of the unloading rail 20 and the guide rail 30 of different models of escalators. The adjusting device 10 is first fixed to the guide rail 30, and then the position of the unloading rail 20 is adjusted so that the top surface of the unloading rail 20 abuts the bottom surface of the fixing plate 3. The unloading rail 20 can be installed in place to avoid installation errors.

[0026] like Figure 2-5 As shown, the bottom surface of the mounting plate 1 includes a first positioning surface 12, and the positioning portion includes a second positioning surface 13 and a protrusion 14 located at the end of the second positioning surface 13 away from the first positioning surface 12; the distance from the second positioning surface 13 to the top surface of the mounting plate 1 is greater than the distance from the first positioning surface 12 to the top surface of the mounting plate 1, and less than the distance from the bottom surface of the protrusion 14 to the top surface of the mounting plate 1. The adjusting member 2 includes a fixing block 21 and two first bolts 22 rotatably connected to the fixing block 21. In this embodiment, the fixing block 21 is provided with two screw holes extending through its width. Each first bolt 22 is rotatably connected to a corresponding screw hole. By rotating the first bolt 22 in the screw hole until the end of the first bolt 22 abuts against the side of the guide rail 30 away from the fixing plate 3 and is tightly abutted therewith, the guide rail 30 is fixed.

[0027] The first positioning surface 12 is connected to the top surface of the fixed block 21. The width of the fixed block 21 is less than the length of the first positioning surface 12, and the length of the first bolt 22 is greater than the length of the first positioning surface 12. This allows a distance between the fixed block 21 and the guide rail 30, and the first bolt 22 has an effective adjustable length in the fixed block 21, which can adjust the length of the first bolt 22 screwed in and out according to the size of different escalator models. The horizontal distance between the side of the protrusion 14 closest to the second positioning surface 13 and the positioning groove 11 is equal to the distance between the unloading rail 20 and the guide rail 30. This ensures a fixed distance between the guide rail 30 and the unloading rail 20, eliminating the need for back-and-forth switching, simplifying operation, and facilitating adjustment of the unloading rail 20 into position. The second positioning surface 13 abuts the top surface of the guide rail 30, and the side of the protrusion 14 closest to the second positioning surface 13 abuts the side of the guide rail 30 away from the adjustment member 2. The width of the guide rail 30 is greater than the length of the second positioning surface 13. The second positioning surface 13 and the protrusion 14 are provided to limit the top surface and the left side surface of the guide rail 30 , and then cooperate with the adjusting member 2 to fix the adjusting device 10 and the guide rail 30 .

[0028] The centerline of the fixing plate 3 and the centerline of the positioning slot 11 are located in the same vertical direction. The height of the fixing plate 3 is greater than the distance from the top surface of the mounting plate 1 to the positioning slot 11, and the width of the positioning slot 11 is equal to the width of the unloading rail 20. By moving the fixing plate 3 up and down along the height direction of the mounting plate 1, the distance that the fixing plate 3 extends from the positioning slot 11 varies. The height of the fixing plate 3 can be adjusted according to the model or tonnage of the escalator. The fixed plate 3 can then be adjusted into position by directly contacting the bottom surface of the fixed fixing plate 3 with the top surface of the unloading rail 20. The width of the positioning slot 11 is equal to the width of the unloading rail 20, which facilitates the adjustment device 10 to secure the unloading rail 20.

[0029] The fixing plate 3 includes a first fixing hole 31 and second fixing holes 32 located on both sides of the first fixing hole 31. Two third fixing holes 33 and two oval holes 34 are provided on the mounting plate 1. The oval holes 34 are provided along the length direction of the mounting plate 1. The second fixing hole 32 is connected to the corresponding oval hole 34 by a second bolt 35. The third fixing hole 33 and the first fixing hole 31 are located on the same vertical line, and the centers of the second fixing hole 32 and the oval holes 34 are located on the same vertical line. By providing the oval holes 34, the adjustment and installation of the fixing plate 3 are more convenient. When the second bolt 35 is located between the top and bottom ends of the oval hole 34, the second portion 42 simultaneously penetrates the first fixing hole 31 and one third fixing hole 33. The limit block 4 includes a first portion 41 and a second portion 42 connected to each other. The length of the first portion 41 is greater than the length of the first fixing hole 31 and the third fixing hole 33, and the thickness of the second portion 42 is equal to the height of the first fixing hole 31 and the third fixing hole 33. Ensure that when the limit block 4 is inserted into the first fixing hole 31 and the third fixing hole 33, the fixing plate 3 can be fixed to the mounting plate 1. The limit block 4 is mainly used to simultaneously pass through the first fixing hole 31 and one of the third fixing holes 33 to mark the height of the unloading rail 20 corresponding to the tonnage of one escalator.

[0030] The adjusting device 10 in this embodiment can be applied to four escalators of different tonnages, that is, when the second bolt 35 is located at the top and bottom ends of the waist hole 34, and the first fixing hole 31 coincides with the two third fixing holes 33 (such as Figure 4 and Figure 5 As shown, the distances that the fixing plate 3 extends beyond the positioning slot 11 vary, corresponding to four different heights. At each height, the fixing plate 3 is pre-positioned, and the adjustment device 10 is then secured to the guide rail 30 via the first positioning surface 12, the positioning portion, and the adjustment member 2. The unloading rail 20 is then adjusted to abut against the fixing plate 3, thereby securing the unloading rail 20. Of course, in other embodiments of the present invention, the number of third fixing holes 33 is not limited to two; more third fixing holes 33 may be provided as needed to meet installation requirements.

[0031] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of protection of the present invention.
