Description

Technical Field

[0001] This utility model relates to the field of escalator truss processing technology, specifically to a support platform for welding escalator trusses. Background Technology

[0002] With the development of the times and the advancement of technology, the application of escalators has become increasingly common, gradually expanding from shopping malls, hotels, and exhibition halls to public places such as banks, hospitals, subways, and airports. The truss base plate is the main component forming the sealed body at the bottom of the escalator. A reasonable truss base plate design plays an important role in improving the rigidity of the truss and the aesthetic appearance of the escalator. During the processing of escalator trusses, welding is required, and a support platform is needed to support them and facilitate welding. Therefore, we provide a support platform for the processing and welding of escalator trusses.

[0003] In existing trusses, the support bars inside the support platform are mostly fixed during welding. This method is inconvenient to use. When the crossbeams of the truss do not correspond to the positions of the support bars, the load-bearing capacity will be reduced, leading to unstable truss welding and thus reducing work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a support platform for the processing and welding of escalator trusses, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A support platform for processing and welding escalator trusses includes a support platform suitable for processing and welding escalator trusses. The support platform includes a support bracket, with support legs fixedly installed around the bottom of the support bracket. Fixed support strips are welded to both ends of the top of the support bracket, and movable support strips are slidably installed on the inner walls of both sides of the support bracket.

[0007] The support bracket is provided with a spacing adjustment unit on both sides, and the movable support strip is provided with a locking unit at both ends.

[0008] A further improvement of the present invention is that the spacing adjustment unit includes through grooves formed on the side frames of the support bracket, and support plates are fixedly installed on both sides of the bottom of the through grooves. Adjustment grooves are formed on both sides of the support bracket above the through grooves.

[0009] A further improvement of this utility model is that: a bearing plate is fixedly installed on both sides of the bottom of the adjustment groove, a fixing cross plate is fixedly installed on the bottom of both sides of the support bracket on the inner wall of the support leg, and teeth are fixedly installed on the top of the fixing cross plate.

[0010] A further improvement of this utility model is that: a movable slider is fixedly installed at both ends of the movable support strip, the movable slider is slidably installed inside the through groove, and a bearing rod is fixedly installed on the outer side of the movable slider.

[0011] A further improvement of this utility model is that a gear is fixedly sleeved on the other end of the bearing rod, and the outer surface of the gear meshes with the teeth.

[0012] A further improvement of the present invention is that the locking unit includes a fixed vertical plate fixedly installed on the top of the movable slider, the other end of the fixed vertical plate extending into the interior of the adjustment groove, and rotating rods fixedly installed on both outer surfaces of the fixed vertical plate.

[0013] A further improvement of this utility model is that a cam is rotatably sleeved on the outer surface of the other end of the rotating rod, and a toggle plate is fixedly installed on the top of the cam.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. This utility model provides a support platform for processing and welding escalator trusses. By moving the actuating plates above both ends of the movable support bar, the cam is rotated and brought into a vertical position. At this time, the convex surface of the cam abuts against the upper part of the bearing plate, which facilitates lifting the movable support bar as a whole upward, causing the gears at both ends to disengage from the teeth of the fixed cross plate. Then, the movable support bar is pushed so that the sliding blocks at both ends slide inside the through groove, which facilitates adjusting the position of the movable support bar according to the position of the cross beam of the truss, thereby improving the convenience and flexibility of use.

[0016] 2. This utility model provides a support platform for processing and welding automatic escalator trusses. After adjusting the spacing, the toggle plate above the movable support bar is moved, thereby driving the cam to rotate so that it is at a 90-degree angle with the fixed vertical plate. At this time, the convex surface of the cam disengages from the bearing plate, causing the movable support bar to move down as a whole. At this time, the gear engages in the teeth above the fixed horizontal plate, achieving a locking state. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figure 1-5As shown, this utility model provides a support platform for processing and welding escalator trusses, including a support platform 1, suitable for processing and welding escalator trusses. The support platform 1 includes a support bracket 2, with support legs 5 fixedly installed around the bottom of the support bracket 2. Fixed support strips 3 are welded to both ends of the top of the support bracket 2. Movable support strips 4 are slidably installed on the inner walls of both sides of the support bracket 2. Spacing adjustment units are provided on both sides of the support bracket 2, and locking units are provided at both ends of the movable support strips 4. The spacing adjustment unit includes through grooves 21 formed on the side frames of the support bracket 2. The inner bottom of the through grooves 21 has fixed support legs 5 on both sides of the support bracket 2. A support plate 211 is fixedly installed. Adjustment grooves 22 are provided on both sides of the support bracket 2 above the through groove 21. Bearing plates 23 are fixedly installed on both sides of the bottom of the adjustment groove 22. Fixed horizontal plates 24 are fixedly installed on the bottom of both sides of the support bracket 2 on the inner wall of the support leg 5. Teeth 25 are fixedly installed on the top of the fixed horizontal plate 24. Moving sliders 41 are fixedly installed at both ends of the moving support bar 4. The moving sliders 41 are slidably installed inside the through groove 21. Bearing rods 42 are fixedly installed on the outer side of the moving sliders 41. Gears 43 are fixedly sleeved on the other end of the bearing rods 42. The outer surface of the gears 43 meshes with the teeth 25.

[0026] Furthermore, by moving the actuating plates 47 above both ends of the movable support bar 4, the cam 46 is rotated and placed in a vertical position. At this time, the convex surface of the cam 46 abuts against the upper part of the bearing plate 23, which facilitates lifting the movable support bar 4 as a whole upward, causing the gears 43 at both ends to disengage from the teeth 25 of the fixed cross plate 24. Then, the movable support bar 4 is pushed so that the sliding blocks 41 at both ends slide inside the through groove 21, which facilitates adjusting the position of the movable support bar 4 according to the position of the cross beam of the truss.

[0027] Example 2

[0028] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the locking unit includes a fixed vertical plate 44 fixedly installed on the top of the movable slider 41, the other end of the fixed vertical plate 44 extends into the interior of the adjustment groove 22, and rotating rods 45 are fixedly installed on both outer surfaces of the fixed vertical plate 44. A cam 46 is rotatably sleeved on the outer surface of the other end of the rotating rod 45, and a toggle plate 47 is fixedly installed on the top of the cam 46.

[0029] Furthermore, after adjustment, by moving the toggle plate 47 above the movable slider 41, the cam 46 is driven to rotate, so that it is at a 90-degree angle with the fixed vertical plate 44. At this time, the convex surface of the cam 46 disengages from the bearing plate 23, causing the movable support bar 4 to move down as a whole. At this time, the gear 43 engages in the teeth 25 above the fixed horizontal plate 24, achieving a locked state.

[0030] The working principle of the support platform for processing and welding the escalator truss will be explained in detail below.

[0031] like Figure 1-5 As shown, during use, by moving the actuating plates 47 above both ends of the movable support bar 4, the cam 46 is rotated and brought to a vertical position. At this time, the convex surface of the cam 46 abuts against the upper part of the support plate 23, which facilitates lifting the movable support bar 4 as a whole upward, causing the gears 43 at both ends to disengage from the teeth 25 of the fixed horizontal plate 24. Then, the movable support bar 4 is pushed so that the sliding blocks 41 at both ends slide inside the through groove 21, which facilitates adjusting the position of the movable support bar 4 according to the position of the truss beam. After adjustment, by moving the actuating plates 47 above the sliding blocks 41, the cam 46 is rotated so that it is at a 90-degree angle to the fixed vertical plate 44. At this time, the convex surface of the cam 46 disengages from the support plate 23, causing the movable support bar 4 to move downward as a whole. At this time, the gears 43 engage with the teeth 25 above the fixed horizontal plate 24, achieving a locked state.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
