Abstract

This utility model discloses a bridge steel support construction rooting device applied in the field of rooting devices. It includes an inverted U-shaped cover, inside which, from top to bottom, are arranged an upper rotating column, two safety columns, and two pairs of lower rotating wheels. The two pairs of lower rotating wheels are located on the left and right inner walls of the inverted U-shaped cover, respectively. The upper rotating column is located between the two safety columns. A central shaft is fixedly connected to both ends of the upper rotating column. The end of the central shaft movably passes through the inverted U-shaped cover and is threaded with an upper nut. A long bolt also movably passes through the outer end of the inverted U-shaped cover corresponding to the safety columns.

This allows the rooting device to move relatively smoothly with the operator. Compared to existing technologies, it eliminates the need for frequent manual adjustments by the operator, effectively reducing the impact on the work process.

Description

Technical Field

[0001] This utility model relates to the field of rooting devices, and in particular to a rooting device for bridge steel support construction. Background Technology

[0002] Bridge steel supports, during long-term use, are affected by factors such as vehicle loads and natural environmental erosion, requiring regular major repairs and maintenance. During major repairs of bridge steel supports, frequent work at heights makes the safety of workers paramount. Traditional safety belt anchoring methods have many drawbacks, such as insufficient stability of the anchoring points and inconvenience in installation and disassembly.

[0003] To address the aforementioned issues, existing rooting devices, designed to improve stability, have a relatively large contact area with the steel support. However, this leads to excessive friction between the device and the support, making relative displacement difficult. For example, the H-shaped steel rooting device disclosed in Chinese Patent CN208235713U is problematic. Furthermore, major overhauls of the steel support are typically performed at heights, which can obstruct workers' movements when changing positions. This necessitates frequent manual adjustments of the rooting device to reposition the workers, thus hindering the progress of the work at height. Utility Model Content

[0004] The core of this invention lies in changing the contact between the rooting device and the steel support to a rolling contact, thereby solving the problem in the prior art that the rooting device is difficult to move smoothly with the operator.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A bridge steel support support anchoring device includes an inverted U-shaped cover. Inside the inverted U-shaped cover, from top to bottom, there are an upper rotating column, two safety columns, and two pairs of lower rotating wheels. The two pairs of lower rotating wheels are located on the left and right inner walls of the inverted U-shaped cover, respectively. The upper rotating column is located between the two safety columns. A central shaft is fixedly connected to both the left and right ends of the upper rotating column. The end of the central shaft movably passes through the inverted U-shaped cover and is threaded with an upper nut. A long bolt also movably passes through the outer end of the inverted U-shaped cover at the corresponding position of the safety column. The end of the long bolt passes through the corresponding safety column and movably extends to the other side of the inverted U-shaped cover. The end of the long bolt outside the inverted U-shaped cover is fastened with a nut. A pad is fixedly connected to both the left and right inner walls of the inverted U-shaped cover. The two pads correspond to the two pairs of lower rotating wheels, respectively. A shaft is fixedly connected to one end of the lower rotating wheel adjacent to the inner wall of the inverted U-shaped cover. The shaft movably passes through the pad and the inverted U-shaped cover and extends to the outside of the inverted U-shaped cover. The end of the shaft outside the inverted U-shaped cover is threaded with a lower nut.

[0007] Furthermore, the upper rotating column and the two pairs of lower rotating wheels contact the top and neck of the steel support, respectively.

[0008] Furthermore, the safety post is higher than the steel support, and the two do not contact each other. The distance between the safety post and the upper surface of the steel support is no greater than the distance between the highest point of the lower wheel and the lower surface of the upper end of the steel support.

[0009] Furthermore, the lower wheel includes a wheel body that contacts the steel bracket and a limiting ring fixedly connected to the outer end of the wheel body. The shaft passes through the limiting ring, and the end of the limiting ring contacts the pad.

[0010] Optionally, elongated holes are drilled on the inverted U-shaped cover and the pad corresponding to the lower rotating wheel. A position compensation unit is provided in the elongated hole on the pad. The position compensation unit includes a positioning section fixedly connected to the bottom of the elongated hole, a fitting section that contacts the lower surface of the shaft, and an adaptive section fixedly connected between the positioning section and the fitting section.

[0011] Furthermore, the upper and lower edges of the elongated hole are both semi-circular, and the part between the two semi-circles is rectangular. The positioning section and the fitting section are both rigid structures, and the adaptive section is a highly resilient structure.

[0012] Furthermore, a pressure sensor is installed in the middle of the outer end of the safety post, and a buffer sleeve is also wrapped around the middle of the outer end of the safety post. The detection end of the pressure sensor faces directly downward and penetrates through the buffer sleeve.

[0013] Compared with existing technologies, the advantages of this utility model are: (1) In this scheme, as the operator's position changes, the upper rotating column and the lower rotating wheel both roll against the steel support, so that the rooting device moves relatively smoothly with the operator. Compared with the prior art, the operator does not need to frequently manually move the rooting device, which effectively reduces the impact on the operation process.

[0014] (2) This scheme also sets up a position compensation unit. When encountering an abnormal protrusion, the lower rotating wheel on the corresponding side can squeeze the position compensation unit under the action of the force, so that the adaptive section undergoes a certain deformation, and the lower rotating wheel can move a certain longitudinal displacement along the long hole, thereby achieving the effect of avoiding the protrusion, making its movement smoother, further reducing the occurrence of manual movement of the Bensing rooting device by the operator, and reducing the impact on the operation.

[0017] The technical solution will now be clearly and completely described with reference to the accompanying drawings in the embodiments of this utility model.

[0018] First implementation method: Figures 1-3 As shown in the figure, 'a' represents a steel support. A type of anchoring device for bridge steel support construction includes an inverted U-shaped cover 1. Inside the inverted U-shaped cover 1, from top to bottom, are arranged an upper rotating column 3, two safety columns 2, and two pairs of lower rotating wheels 4. The two pairs of lower rotating wheels 4 are located on the left and right inner walls of the inverted U-shaped cover 1, respectively. The upper rotating column 3 is located between the two safety columns 2. A central shaft is fixedly connected to both ends of the upper rotating column 3. The end of the central shaft movably passes through the inverted U-shaped cover 1 and is threaded with an upper nut 51. A long bolt 21 movably passes through the outer end of the inverted U-shaped cover 1 at the corresponding position of the safety column 2. The end of the long bolt 21 passes through the corresponding safety column 2 and movably extends to the other side of the inverted U-shaped cover 1. The end of the long bolt 21 outside the inverted U-shaped cover 1 is fastened with a nut. In use, as... Figure 3 The two pairs of lower rotating wheels 4 are in contact with the lower surface of the upper end of the steel support, and the upper rotating column 3 is in contact with its upper surface. During construction, the workers can hang their safety belts on the hanging rings 101. As the workers' construction positions change, the upper rotating column 3 and the lower rotating wheels 4 roll and move with the steel support, thereby allowing the Bunsen rooting device to move smoothly, facilitating safe and stable construction.

[0019] It is worth noting that the steel support in this embodiment specifically refers to H-beams.

[0020] Both the left and right inner walls of the inverted U-shaped cover 1 are fixedly connected with pads 6. The two pads 6 correspond to the two pairs of lower rotating wheels 4 respectively. The pads 6 are mainly used to strengthen the bottom of the inverted U-shaped cover 1. When the connection point between the worker and the safety belt is higher than the Bunsen anchoring device, the force on the Bunsen anchoring device is mainly concentrated at the lower rotating wheels 4. Therefore, when the Bunsen anchoring device moves along the steel support with the worker, the force on the lower rotating wheels 4 is greater. Due to the reinforcement of the pads 6, the connection between the inverted U-shaped cover 1 and the lower rotating wheels 4 is not easily deformed due to the force, thus effectively ensuring the stability of the Bunsen anchoring device. One end of the lower rotating wheel 4 near the inner wall of the inverted U-shaped cover 1 is fixedly connected with a shaft 501. The shaft 501 movably passes through the pads 6 and the inverted U-shaped cover 1 and extends to the inverted U-shaped cover 1. Outside the cover 1, the end of the shaft 501 located outside the inverted U-shaped cover 1 is threaded with a lower nut 52. The lower rotating wheel 4 includes a wheel body 41 that contacts the steel bracket and a limiting ring 42 fixedly connected to the outer end of the wheel body 41. The shaft 501 passes through the limiting ring 42, and the end of the limiting ring 42 contacts the pad 6. The upper rotating column 3 and the two pairs of lower rotating wheels 4 contact the top and neck of the steel bracket respectively, so that the lower rotating wheel 4 can rotate about the shaft 501 as the axis, and the upper rotating column 3 can rotate about the central axis. When the Benseng rooting device moves with the operator, rolling friction occurs between it and the steel bracket, rather than sliding friction, thereby effectively reducing friction and making it move more smoothly with the operator without causing any obstruction.

[0021] like Figure 6 The pressure sensor 202 and buffer sleeve 201 can be selectively installed according to actual needs. The pressure sensor 202 is installed in the middle of the outer end of the safety post 2. When using it, those skilled in the art can select the appropriate model of pressure sensor 202 according to actual needs, such as MPX5700AP. An alarm connected to the signal of the pressure sensor 202 is installed on the inverted U-shaped cover 1. When using it, those skilled in the art can select the appropriate model of alarm according to actual needs, such as LTE-5061J. The middle of the outer end of the safety post 2 is also wrapped with a buffer sleeve 201. The detection end of the pressure sensor 202 faces directly downward and penetrates the buffer sleeve 201. When the central shaft of the upper rotating post 3 breaks or is excessively deformed, it will cause the safety post 2 to contact the steel support. At this time, it will generate a squeezing force on the pressure sensor 202, which will trigger the alarm, thereby directly warning the operators and greatly reducing the safety hazards caused by the abnormality of the rooting device.

[0022] like Figure 3The safety post 2 is higher than the steel support, and the two do not contact each other. The distance between the safety post 2 and the upper surface of the steel support is no greater than the distance between the highest point of the lower rotating wheel 4 and the lower surface of the upper end of the steel support. When the connection point between the worker and the safety belt is lower than the Bunsen anchoring device, the force on the Bunsen anchoring device is mainly applied to the upper rotating post 3. Since there is only one upper rotating post 3, if the central shaft on it is deformed or broken, the stability of the connection between the Bunsen anchoring device and the steel support will be greatly affected. Therefore, the safety post 2 is set to limit the longitudinal change between the inverted U-shaped cover 1 and the steel support when this happens, thereby effectively ensuring stability and making it difficult for the inverted U-shaped cover 1 to detach directly from the steel support.

[0023] In addition, since there are four lower rotating wheels 4, it is difficult for them all to break at once. Therefore, when one of them malfunctions, its impact on stability is far less than the impact of the upper rotating column 3 malfunction on stability. Therefore, the inverted U-shaped cover 1 does not have a corresponding safety column 2 on the side near the lower rotating wheel 4.

[0024] In use, the operator first unscrews multiple lower nuts 52 with a wrench to remove multiple lower rotating wheels 4. Then, the inverted U-shaped cover 1 is placed on the steel support, and the multiple lower rotating wheels 4 are then installed back onto the inverted U-shaped cover 1 in sequence. At this time, the upper rotating column 3 and the four lower rotating wheels 4 are in contact with the steel support. After that, the operator hangs the hook on the safety belt onto the hanging ring 101. As the operator's working position changes, the upper rotating column 3 and the lower rotating wheels 4 roll and rub against the steel support, so that the rooting device moves relatively smoothly with the operator. Compared with the existing technology, the operator does not need to frequently manually move the rooting device, effectively reducing the impact on the operation process.

[0025] Second implementation method: This embodiment is based on the first embodiment, with the addition of a new growth hole 102 and a position compensation unit disposed thereon, while the rest remains the same as the first embodiment.

[0026] Figure 4 As shown, elongated holes 102 are drilled on the inverted U-shaped cover 1 and the pad 6 at positions corresponding to the lower rotating wheel 4, such as... Figure 5A position compensation unit is installed inside the elongated hole 102 on the pad 6. The position compensation unit includes a positioning section 71 fixedly connected to the bottom of the elongated hole 102, a fitting section 73 in contact with the lower surface of the shaft 501, and an adaptive section 72 fixedly connected between the positioning section 71 and the fitting section 73. The upper and lower edges of the elongated hole 102 are semi-circular, and the part between the two semicircles is rectangular. The positioning section 71 and the fitting section 73 are both rigid structures, and the adaptive section 72 is a highly resilient structure. During the movement of the Bunsen rooting device with the operator, when there is an abnormal protrusion on the surface of the steel support, it will seriously... The smoothness of the movement of the rooting device is affected by the fact that operators need to constantly adjust its position manually. To address this issue, a position compensation unit is set up. When it encounters an abnormal protrusion, the lower roller 4 on the corresponding side can squeeze the position compensation unit under the action of the force, causing the adaptive section 72 to deform to a certain extent. This allows the lower roller 4 to move longitudinally along the elongated hole 102, thereby avoiding the protrusion and making its movement smoother. Compared with the first implementation method, this effectively reduces the need for operators to manually move the position of the rooting device, reducing the impact on the operation.

[0027] It is worth noting that the compressible range of the adaptive segment 72 is no greater than the distance between the safety post 2 and the steel bracket under normal conditions, thereby effectively ensuring that the lower rotating wheel 4 does not easily affect the stability of the Bunsen rooting device when avoiding the protrusion. Therefore, the protrusion that can be avoided in this embodiment is a relatively small protrusion.

[0028] The above description is merely a preferred embodiment of this utility model; it encompasses all the protection scope of this utility model. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be covered within the protection scope of this utility model.
