DETAILED DESCRIPTION

[0027] The present application will now be further described in detail with reference to the accompanying drawings.

[0028] Please refer to Figures 1-3 shown, a safety support bracket for high-speed rail bridge construction is provided in the embodiment, which comprises.

[0029] The application of an aspect of the present embodiment is: a safety support bracket for high-speed rail bridge construction. It should be noted that all electrical equipment involved in the present application can be powered by a battery or an external power source.

[0030] As Figure 1 , 2As shown, the metal pull rope 3 of the embodiment is fixed at one end of the fixed rod 102 and wound, the upper end is wound from the top of the rotating rod 103, and the bottom is finally wound and installed on the winding rod 202. The motor 203 is started to drive the winding rod 202 to rotate, the metal pull rope 3 is wound to shorten the length of the external metal pull rope 3, and the distance between the rotating rod 103 and the winding rod 202 is shortened by winding, and the winding rods 202 on both sides rotate synchronously to make the lifting plate 2 horizontally lifted, thereby facilitating the operator to perform construction work on the high bridge position. The surface of the rotating rod 103 is attached to the metal pull rope 3 to follow the rotation to reduce friction, and the console 4 is installed on the lifting plate 2 to start and stop the motor 203 by setting the internal wire in the lifting plate 2 to follow the lifting, so that the construction worker can adjust the height of the lifting plate 2.

[0031] As shown in Figure 2 , 3 As shown, the guide column 105 of the embodiment is in a concave shape, the inside is opened to the sliding groove 106, and the opening direction is towards the position of the lifting plate 2. The roller frame 207 installed in the adjusting inner cavity 204 of the lifting plate 2 corresponds to the sliding groove 106, the center of the roller frame 207 passes through the roller shaft and is installed with the roller 208, the diameter of the roller 208 is smaller than the groove width of the sliding groove 106, so that the roller 208 does not contact the groove wall of the sliding groove 106 on both sides at the same time. A part of the roller frame 207 extending out of the adjusting inner cavity 204 is installed with the roller 208 in the center, the center passing through the spring column 205 and being supported by the spring 206 on both sides, when the lifting plate 2 shakes forward and backward during the lifting process, the roller 208 contacts the wall of the sliding groove 106, so that the position of the roller frame 207 on the spring column 205 is offset, thereby pressing the spring 206 on one side, and the two springs 206 release the elastic force to quickly make the roller frame 207 return to the center position, thereby reducing the shaking time and amplitude of the lifting plate 2, and ensuring the balance.

[0032] As shown in Figure 1 As shown, the entire lifting plate 2 of the embodiment is surrounded by the fence 401 on the top, which protects the operator from falling during high-altitude construction, and the fence 401 is supported by multiple vertical rods 402 and has an entrance opposite the console 4. The rail of the entrance is set as a flip door 403 by a rotating shaft, which is convenient to open and close.

[0033] As shown in Figure 2 , 3As shown, the side frame 101 of the embodiment is attached to the lifting plate 2, the winding support 201 is arranged on the extension plate 209 extended from both sides of the lifting plate 2, so that the winding support 201 and the winding rod 202 extend into the space between the side frames 101, and the rotating rod 103 at the top extends to the direction of the winding rod 202, so that the rotating rod 103 and the winding rod 202 are close to each other in the vertical direction, and the distance between them is the width of the metal pull rope 3, so that the metal pull rope 3 is perpendicular to the downward direction when it is connected to the rotating rod 103 and the winding rod 202, and the force is perpendicular to the upward direction when it is wound, so that the force is not dispersed in other directions, and the whole lifting is more labor-saving, the extension part of the side frame 101 at the top is used for mounting the rotating rod 103, and the extension part cannot be too much, otherwise the motor 203 will hit the side frame 101 when the lifting plate 2 rises, and the part of the side frame 101 suspended below the rotating rod 103 is reinforced by the support frame 104 to prevent deformation of this area.

[0034] As shown, Figure 2 The multiple metal pull ropes 3 of the embodiment are wound synchronously, the stress of each metal pull rope 3 is reduced, and the service life of the metal pull rope 3 is longer.

[0035] Embodiment 1:

[0036] In the embodiment, the operator logs in the area of the lifting plate 2, starts the motors 203 on both sides through the control console 4 to rotate, drives the winding rod 202 to rotate with the cloth to wind the metal pull rope 3, shortens the distance between the rotating rod 103 and the winding rod 202, thereby lifting the lifting plate 2, so that the operator can contact the higher bridge position to reduce the labor operation, and the control console 4 rises and falls with the lifting platform 2, so that the operator can adjust the height of the lifting plate 2 at any time during work.

[0037] Embodiment 2:

[0038] In the embodiment, when the lifting plate 2 shakes forward and backward during the rising process, the roller 208 contacts the wall of the sliding groove 106, so that the position of the roller frame 207 on the spring column 205 is offset, thereby allowing the roller frame 207 to press one side of the spring 206, the two springs 206 release the elastic force to quickly make the roller frame 207 return to the center position, and reversely push the inner wall of the adjusting cavity 204 to reset the lifting plate 2, thereby reducing the shaking time and amplitude of the lifting plate 2 and ensuring the balance of the lifting plate 2 during the lifting process.

[0039] The utility model is not limited to the above-mentioned embodiments, anyone should know that the structural changes made under the inspiration of the utility model, any technical scheme with the same or similar technical scheme of the utility model falls within the protection scope of the utility model. The utility model does not describe the technology, shape and structure part in detail, which is the known technology.
