Description

Technical Field

[0001] This utility model relates to the field of bridge erection technology, and more specifically, to a safety protection device applied to a cap beam across a highway. Background Technology

[0002] Currently, when constructing cap beams, especially those spanning highways, the construction height is considerable, making it a high-altitude operation. Therefore, it is necessary to build safety protection platforms to prevent construction workers and tools from falling from heights.

[0003] Common methods for constructing safety protection platforms include erecting temporary steel pipe frames, directly using lifting equipment to set up cages, or using fixed platform construction. All three methods have high requirements for site conditions, especially the occupation of existing roads. This makes it impossible to carry out the construction of the cap beam across the road when the road needs to be open to traffic, thus reducing the efficiency of the cap beam construction across the road. Utility Model Content

[0004] The problem this utility model solves is: how to achieve the construction of cap beams across highways when the highway needs to be open to normal traffic, so as to improve the construction efficiency of cap beams across highways.

[0005] To address the aforementioned problems, this utility model provides a safety protection device for use on a highway overpass, comprising two protection platforms and a traveling frame connected between the two protection platforms. The two protection platforms are distributed on both sides of the overpass in the width direction. Each protection platform includes a walkway platform for movement. The traveling frame is movably mounted on the overpass, and the direction of movement is consistent with the extension direction of the overpass.

[0006] Optionally, the traveling frame includes multiple crossbars and multiple traveling wheels. Each crossbar extends along the width direction, which is perpendicular to the direction of movement. The multiple crossbars are arranged parallel to each other along the direction of movement. Each crossbar has a traveling wheel at both ends in the axial direction. The multiple traveling wheels are used to roll on the top of the cover beam. The multiple crossbars are detachably connected between the two protective platforms.

[0007] Optionally, the crossbar includes multiple connecting rods, which are arranged sequentially along the width direction. In each crossbar, any two adjacent connecting rods are detachably connected by a pin.

[0008] Optionally, the traveling wheels are configured as rubber rollers.

[0009] Optionally, the protective platform further includes a platform support frame, the top of which is connected to the traveling frame, the bottom of which extends to the underside of the traveling frame and is connected to the walkway platform, and the platform support frame is also provided with traveling wheels for rolling on the end face of the cover beam in the width direction.

[0010] Optionally, the walking wheels are rubber wheels.

[0011] Optionally, the protective platform further includes a platform brace, which is inclined and located below the walkway platform, and the platform brace is connected between the walkway platform and the platform support frame.

[0012] Optionally, the protective platform further includes a guardrail connected to the walkway platform and located at one end of one walkway platform away from the other walkway platform.

[0013] Optionally, the guardrail includes a movable protective part and a fixed protective part. The fixed protective part is fixedly connected to the walkway platform, and the movable protective part is located above the fixed protective part and is slidably connected to the fixed protective part in the vertical direction.

[0014] Optionally, the fixed protective part is provided with a sleeve, the movable protective part is provided with a sliding rod, the sleeve extends in a vertical direction, the sliding rod is slidably connected to the sleeve, and the sleeve is provided with a locking pin, which penetrates the sleeve radially and is used to engage with the sliding rod.

[0015] Optionally, the walkway platform is paved with patterned steel plates.

[0016] Compared with related technologies, the safety protection device of this utility model applied to the cap beam across the highway is moved and set on the cap beam by a traveling frame connected between two protection platforms. Under the connection of the traveling frame, the two protection platforms can be erected at high altitude, thus avoiding the occupation of the original highway by the construction of the two protection platforms. By moving the traveling frame in the same direction as the extension direction of the cap beam, the traveling frame can reach any position in the extension direction of the cap beam, thereby enabling the two protection platforms to be moved to any position on the cap beam. The two protection platforms can be used flexibly. Furthermore, the walkway platform on each protection platform can be used for walking, providing high-altitude walking space for workers. Thus, when working at height, high-altitude operations can be carried out simultaneously on both sides of the cap beam in the width direction, improving the efficiency of high-altitude operations while ensuring the normal traffic flow of the highway.

[0029] Combination Figure 1 , Figure 3 As shown, this utility model embodiment provides a safety protection device applied to a highway overpass, including two protection platforms 1 and a traveling frame 2 connected between the two protection platforms 1. The two protection platforms 1 are distributed on both sides of the overpass 3 in the width direction. Each protection platform 1 includes a walkway platform 11 for walking. The traveling frame 2 is movably mounted on the overpass 3, and the direction of movement is consistent with the extension direction of the overpass 3.

[0030] Specifically, the width direction of cap beam 3 refers to the X-axis direction, and the two sides of the width direction of cap beam 3 are the two sides of cap beam 3 in the X-axis direction. For example Figure 1 As shown, two protective platforms 1 are respectively distributed on both sides of the width direction of the cap beam 3. Each protective platform 1 is equipped with a walkway platform 11, as shown in the figure. Figure 3 As shown, the walkway platform 11 can extend along the length of the cap beam 3, which is along the Y-axis. Each walkway platform 11 can provide walking space for workers performing high-altitude operations. Figure 3 As shown, a traveling structure 2 is provided between the two protective platforms 1. The two ends of the traveling structure 2 in the X-axis direction are connected to the two protective platforms 1 respectively. The traveling structure 2 can move on top of the cap beam 3, and the direction of movement of the traveling structure 2 is consistent with the length direction of the cap beam 3, that is, the traveling structure 2 can move along the Y-axis direction. When performing high-altitude operations on the cap beam 3, the two protective platforms 1 are installed on top of the cap beam 3 through the traveling structure 2, and the two protective platforms 1 can move along the extension direction of the cap beam 3 through the traveling structure 2. This allows for high-altitude operations on the cap beam 3 without occupying the highway, thus solving the problem of cap beam construction across the highway when normal highway traffic is required.

[0031] Therefore, in this embodiment, the traveling frame 2 connected between the two protective platforms 1 is moved and set on the cap beam 3. Under the connecting action of the traveling frame 2, the two protective platforms 1 are erected at high altitude, thereby avoiding the occupation of the original road by the erection of the two protective platforms 1. Since the moving direction of the traveling frame 2 is consistent with the extension direction of the cap beam 3, the traveling frame 2 can reach any position in the extension direction of the cap beam 3, thereby enabling the two protective platforms 1 to be moved to any position on the cap beam 3. The two protective platforms 1 can be used flexibly. Furthermore, the walkway platform 11 on each protective platform 1 can be used for walking. The walkway platform 11 can provide high-altitude walking space for workers. Thus, when working at high altitude, high-altitude operations can be carried out simultaneously on both sides of the width direction of the cap beam 3, improving the efficiency of high-altitude operations while ensuring the normal traffic flow of the road.

[0032] Optionally, combined Figure 1 and Figure 3 As shown, the traveling frame 2 includes multiple crossbars 21 and multiple traveling wheels 22. Each crossbar 21 extends along the width direction, which is perpendicular to the direction of movement. The multiple crossbars 21 are arranged parallel to each other along the direction of movement. Each crossbar 21 has a traveling wheel 22 at both ends in the axial direction. The multiple traveling wheels 22 are used to roll on the top of the cover beam 3. The multiple crossbars 21 are detachably connected between the two protective platforms 1.

[0033] Specifically, each crossbar 21 extends along the width direction of the cover beam 3, that is, each crossbar 21 extends along the X-axis direction. The width direction of the cover beam 3 is consistent with the movement direction of the traveling frame 2, which is along the Y-axis direction. Multiple crossbars 21 are distributed parallel to each other along the Y-axis direction and are located above the cover beam 3. Each crossbar 21 is equipped with a traveling wheel 22 at both ends in the axial direction. The traveling wheels 22 can be mounted on the bottom of the crossbar 21 through wheel brackets. Multiple crossbars 21 are welded between the two protective platforms 1. Through the connection of multiple crossbars 21, the two protective platforms 1 can move along the extension direction of the cover beam 3.

[0034] Thus, by extending each crossbar 21 along the width direction of the cover beam 3, and with the width direction of the cover beam 3 perpendicular to the moving direction of the traveling frame 2, multiple crossbars 21 are detachably connected between the two protective platforms 1. This allows the two protective platforms 1 to be located on both sides of the cover beam 3 through the connection of multiple crossbars 21. Furthermore, by setting multiple crossbars 21 parallel to each other along the moving direction, multiple crossbars 21 can form a frame structure between two crossbars 21, thereby reducing the weight of the traveling frame 2 and reducing the load on the cover beam 3. Then, by setting a traveling wheel 22 at each end of the axial direction of each crossbar 21, multiple traveling wheels 22 roll on the top of the cover beam 3, allowing multiple crossbars 21 to move on the top of the cover beam 3 along the extension direction of the cover beam 3, thereby realizing the movement of the two protective platforms 1 on the cover beam 3 and simplifying the movement method of the two protective platforms 1 on the cover beam 3. Since the protective platform 1 often extends along the extension direction of the cover beam 3, the length of the protective platform 1 is generally relatively long. When moving, the two protective platforms 1 can be moved by manually pushing the traveling frame 2.

[0035] Optionally, combined Figure 1 and Figure 3 As shown, the crossbar 21 includes multiple connecting rods 211, which are arranged sequentially along the width direction. In each crossbar 21, any two adjacent connecting rods 211 can be detachably connected by a pin.

[0036] Specifically, such as Figure 1 As shown, each crossbar 21 may include four connecting rods 211, which are arranged sequentially along the width direction of the cap beam 3. The two ends of two adjacent connecting rods 211 can be detachably connected by a pin, or the pin can be replaced by a bolt. Figure 3 As shown, the traveling frame 2 moves on the cover beam 3. When there are no obstacles in the direction of movement of the traveling frame 2, the traveling frame 2 moves normally along the extension direction of the cover beam 3 (i.e., the Y-axis direction). When there are obstacles in the direction of movement of the traveling frame 2, and the height of the obstacles is higher than the height of the connecting rod 211, such as... Figure 4 As shown, the pins of the four connecting rods 211 can be pulled out from the two ends of the two middle connecting rods 211 that interfere with and collide with the obstacle, so that the two middle connecting rods 211 can rotate around the pins at their other ends, as shown. Figure 5 As shown. After rotation, the two connecting rods 211 can create clearance space, allowing the vehicle frame 2 to continue moving, as... Figure 6 As shown, the obstacle can be avoided by the clearance space, allowing the horizontal bar 21 to avoid the obstacle, and after complete avoidance, as... Figure 7 As shown, the two connecting rods 211 in the middle are connected again by a pin, and this process is repeated to ensure that all crossbars 21 can avoid obstacles on the top of the cap beam 3.

[0037] Since the two protective platforms 1 are connected by multiple crossbars 21, and the multiple crossbars 21 are distributed in parallel along the extension direction of the cover beam 3, in actual application, each crossbar 21 can provide support for the two protective platforms 1. When two connecting rods 211 of a certain crossbar 21 are disassembled, the remaining crossbars 21 can still ensure the required support effect for the two protective platforms 1. Therefore, the stability of the two protective platforms 1 when avoiding obstacles can be guaranteed.

[0038] Thus, by arranging multiple connecting rods 211 sequentially along the width of the cover beam 3, and by detachably connecting any two adjacent connecting rods 211 in each crossbar 21 via a pin, when an obstacle is encountered on the cover beam 3, the connection between the two connecting rods 211 that collide with the obstacle can be released, thereby enabling each crossbar 21 to avoid obstacles. Furthermore, the actual number of connecting rods 211 connected can be selected to adapt to cover beams 3 of different widths, ensuring that the traveling frame 2 moves on the cover beam 3 while also improving the traveling safety and flexibility of the traveling frame 2.

[0039] Optionally, the walking wheel 22 is configured as a rubber roller.

[0040] Specifically, the traveling wheels 22 can be rubber rollers. Two rubber rollers are respectively mounted at both ends of the length of each crossbar 21 via wheel frames. That is, among the multiple connecting rods 211 in each crossbar 21, two rubber rollers are respectively mounted at the ends of the leftmost and rightmost connecting rods 211 via wheel frames. Thus, by setting the traveling wheels 22 as rubber rollers, the rubber material of the rollers can reduce the vibration generated when the traveling wheels 22 roll on the top of the cap beam 3, thereby achieving a certain vibration damping effect.

[0041] Optionally, combined Figure 1 As shown, the protective platform 1 also includes a platform support 12. The top of the platform support 12 is connected to the traveling frame 2, and the bottom of the platform support 12 extends to the bottom of the traveling frame 2 and is connected to the walkway platform 11. The platform support 12 is also provided with rollers 121, which are used to roll on the end face of the cover beam 3 in the width direction.

[0042] Specifically, the platform support 12 extends vertically. The top of the platform support 12 is connected to the left or right end of the traveling frame 2 by welding or other means. The bottom of the platform support 12 is located below the traveling frame 2, so that the cover beam 3 is located between two platform supports 12, and each platform support 12 is also provided with a roller 121, which can roll on the left and right end faces of the cover beam 3 in the width direction.

[0043] Thus, by connecting the top of the platform support 12 to the traveling frame 2 and extending its bottom below the traveling frame 2 to connect with the walkway platform 11, the height of the walkway platform 11 is reduced, thereby lowering the working height and improving the safety of working at height. Furthermore, rollers 121 are installed on the platform support 12, which roll on the end face of the cover beam 3 in the width direction. Each platform support 12 receives support from the cover beam 3 through the rollers 121, improving the structural stability of the platform support 12. Simultaneously, the rollers 121 on the two platform support 12s also guide the movement of the traveling frame 2, improving the accuracy of its movement and further enhancing the safety of working at height.

[0044] Optionally, combined Figure 1 As shown, the protective platform 1 also includes a platform brace 13, which is inclined and located below the walkway platform 11, and the platform brace 13 is connected between the walkway platform 11 and the platform support 12.

[0045] Specifically, the walkway platform 11 is located in the horizontal direction, and the end of the walkway platform 11 near the cap beam 3 is connected to the platform support 12. The platform diagonal brace 13 is set at an angle and is located below the walkway platform 11, with the upper end of the platform diagonal brace 13 connected to the bottom of the walkway platform 11 and the lower end of the platform diagonal brace 13 connected to the platform support 12.

[0046] Thus, by setting the platform diagonal brace 13 at an angle and placing it below the walkway platform 11, and by connecting the walkway platform 11 and the platform support frame 12, the platform diagonal brace 13 can support the walkway platform 11 from below, thereby improving the load-bearing capacity of the walkway platform 11.

[0047] Optionally, combined Figure 1 As shown, the protective platform 1 also includes a guardrail 14, which is connected to the walkway platform 11 and located at one end of the walkway platform 11 away from the other walkway platform 11.

[0048] Specifically, each walkway platform 11 is equipped with a guardrail 14, which can be welded to one end of one walkway platform 11 away from another. In this way, the guardrail 14 can prevent personnel from falling from heights, thereby improving operational safety.

[0049] Optionally, combined Figure 1 and Figure 2 As shown, the guardrail 14 includes a movable protective part 141 and a fixed protective part 142. The fixed protective part 142 is fixedly connected to the walkway platform 11, and the movable protective part 141 is located above the fixed protective part 142 and is slidably connected to the fixed protective part 142 in the vertical direction.

[0050] Specifically, when the height of the guardrail 14 needs to be increased, the movable protective part 141 can slide upward relative to the fixed protective part 142 to increase the height of the guardrail 14. When the height of the guardrail 14 needs to be decreased, the movable protective part 141 can slide downward relative to the fixed protective part 142 to decrease the height of the guardrail 14.

[0051] Thus, by fixing the protective part 142 to the walkway platform 11, and by placing the movable protective part 141 above the fixed protective part 142 and sliding it vertically to the fixed protective part 142, the height of the guardrail 14 can be flexibly adjusted, thereby improving the flexibility of the guardrail 14 in use.

[0052] Optionally, a sleeve is provided on the fixed protective part 142, and a slide rod is provided on the movable protective part 141. The sleeve extends in the vertical direction, and the slide rod is slidably connected to the sleeve. A locking pin is provided on the sleeve, which penetrates the sleeve radially and is used to be inserted into the slide rod.

[0053] Specifically, the sleeve and the sliding rod extend vertically. The sleeve is mounted on the fixed protective part 142, and the sliding rod is mounted on the movable protective part 141. The sliding rod has multiple positioning holes, and the sleeve has multiple through holes that penetrate the sleeve radially. When the movable protective part 141 moves to a suitable height, a pin passes through the through hole and engages with the positioning hole on the sliding rod, restricting the sliding of the sliding rod and thus locking it. In this way, while allowing the movable protective part 141 to slide relative to the fixed protective part 142, the movable protective part 141 can be locked in time at the required position, thereby improving the reliability of the guardrail 14.

[0054] Optionally, patterned steel plates may be laid on the walkway platform 11.

[0055] Specifically, the patterned steel plate is installed on the walkway platform 11 with screws. In this way, the striped structure on the surface of the patterned steel plate can improve the friction between the walkway platform and the sole of the shoe, play a role in preventing slipping, and improve the safety of walking at heights.

[0056] Optionally, the edge of the patterned steel plate is provided with a high kick plate.

[0057] Specifically, high kick plates are installed along the circumferential edge of the patterned steel plate. The function of the high kick plate can be understood as a baffle or edge guard. The high kick plate and the patterned steel plate form an upward-opening groove-like structure. Within the area enclosed by this groove-like structure, tools can be prevented from falling from a height. This improves operational safety.

[0058] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
