Description

Technical Field

[0001] This application relates to the field of bridge construction equipment, and more specifically, to a safety protection platform for high-altitude operations during bridge construction. Background Technology

[0002] In bridge construction or maintenance, such as repairing defects in wing panels, installing drainage pipes, or installing rain shelters on the outer side of bridge eaves, it is often necessary to use construction auxiliary equipment to get close to the work surface. Existing construction equipment includes construction vehicles equipped with suspension devices. The work platform is mounted on the suspension device, which can move the work platform to the side of the bridge for construction. However, since there is a certain distance between the work platform and the side of the bridge, adjusting the distance requires adjusting the position of the vehicle body to adjust the position of the work platform. However, adjusting the vehicle body is not convenient. The vehicle body is equipped with a hydraulic mechanism to stabilize the vehicle body and prevent it from tipping over. Therefore, adjusting the vehicle body requires storing the work platform and the hydraulic device, making the adjustment process cumbersome. To address this, we propose a safety protection platform for high-altitude bridge construction operations. Utility Model Content

[0003] To overcome the above shortcomings, this application provides a safety protection platform for high-altitude operations in bridge construction, which aims to improve the problem of inconvenient adjustment of the distance between the existing operation platform and the side of the bridge.

[0004] This application provides a safety protection platform for high-altitude operations in bridge construction, including a vehicle body, a suspension device installed on the vehicle body, a connecting seat installed at the bottom of the suspension device, an installation groove opened on one side wall of the connecting seat, a horizontal moving mechanism installed in the installation groove, and a protective platform body installed at one end of the horizontal moving mechanism.

[0005] In one specific implementation, a groove is provided at the bottom of the mounting slot, and a drive mechanism is installed in the groove. The drive mechanism is connected to the horizontal moving mechanism.

[0006] In one specific implementation, the horizontal moving mechanism includes two rectangular blocks, both of which are slidably disposed in the mounting groove, and both of which have sliders fixedly installed at their bottoms. The two sliders are connected to the driving mechanism, and one end of each of the two rectangular blocks is fixedly connected to the protective platform body.

[0007] In one specific implementation, the driving mechanism includes two threaded rods, both of which are rotatably connected to the inner wall of the groove, and the two sliders are respectively slidably sleeved on the two threaded rods.

[0008] In one specific implementation, the drive mechanism further includes a motor installed in the groove and a transmission rod installed in the groove, wherein the motor is driven by the two transmission rods and the two threaded rods.

[0009] In one specific implementation, the protective platform body includes a platform body, a connecting plate is fixedly installed on one side wall of the platform body, and both rectangular blocks are fixedly connected to the connecting plate.

[0010] In one specific implementation, a plurality of limiting rails are fixedly installed at the bottom of the connecting seat, and a limiting block is slidably provided in each of the plurality of limiting rails. A connecting rod is fixedly connected to the bottom of each of the plurality of limiting blocks, and one end of each of the plurality of connecting rods is connected to the side wall of the connecting plate.

[0011] In one specific implementation, a T-shaped groove is provided in the limiting rail, and the limiting block is T-shaped and slidably disposed in the T-shaped groove.

[0012] The beneficial effects of this application are as follows: By installing a connecting seat at the bottom of the suspension device, opening an installation groove on the connecting seat, and opening a recess at the bottom of the installation groove, installing a drive mechanism in the recess, and installing a horizontal moving mechanism in the installation groove, the drive mechanism can drive the horizontal moving mechanism to move. The protective platform body is connected to the horizontal moving mechanism, which makes it easy to adjust the distance between the protective platform body and the side of the bridge. By installing several limiting rails at the bottom of the connecting seat, installing limiting blocks in the limiting rails, and installing connecting rods at the bottom of the limiting blocks, the connecting rods are connected to the protective platform body, which can achieve the purpose of auxiliary support for the protective platform body.

Detailed Implementation

[0019] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0020] Please see Figure 1-4 This application provides a safety protection platform for high-altitude operations during bridge construction, including a vehicle body 10. A suspension device 20 is installed on the vehicle body 10, and a connecting seat 30 is installed at the bottom of the suspension device 20. An installation groove 40 is opened on one side wall of the connecting seat 30, and a horizontal moving mechanism 50 is installed in the installation groove 40. A protective platform body 60 is installed at one end of the horizontal moving mechanism 50. Specifically, the suspension device 20 can drive the connecting seat 30 to move to one side of the bridge, thereby moving the protective platform body 60 to one side of the bridge. When it is necessary to adjust the distance between the protective platform body 60 and the bridge, the horizontal moving mechanism 50 can drive the protective platform body 60 to move horizontally, thereby adjusting the distance between the protective platform body 60 and the bridge.

[0021] See Figure 4 The bottom of the mounting slot 40 is provided with a groove 410, and a drive mechanism 70 is installed in the groove 410. The drive mechanism 70 is connected to the horizontal moving mechanism 50. Furthermore, the drive mechanism 70 drives the horizontal moving mechanism 50 to move, so as to drive the protective platform body 60 to move horizontally.

[0022] See Figure 4 The horizontal moving mechanism 50 includes two rectangular blocks 510, both of which are slidably disposed in the mounting groove 40, and both of which have a slider 520 fixedly mounted on their bottom. The two sliders 520 are connected to the drive mechanism 70. One end of the two rectangular blocks 510 is fixedly connected to the protective platform body 60. When set up, the rectangular blocks 510 are slidably contacted with the top of the mounting groove 40. The drive mechanism 70 drives the sliders 520 to move horizontally, so that the sliders 520 drive the rectangular blocks 510 to move horizontally.

[0023] See Figure 4The drive mechanism 70 includes two threaded rods 710, both of which are rotatably connected to the inner wall of the groove 410. Two sliders 520 are slidably sleeved on the two threaded rods 710 respectively. In a specific configuration, the two ends of the threaded rods 710 are rotatably connected to the two end side walls of the groove 410 respectively. When the threaded rods 710 rotate, they will drive the sliders 520 on them to slide on the bottom of the groove 410.

[0024] See Figure 4 The drive mechanism 70 also includes a motor 720 installed in the groove 410 and a transmission rod 730 installed in the groove 410. The motor 720 is driven by two threaded rods 710 through two transmission rods 730. It should be noted that a mounting block is fixedly installed at the bottom of the groove 410. The transmission rod 730 rotates through the two mounting blocks. At the same time, a first bevel gear is fixedly sleeved on each of the two threaded rods 710. A second bevel gear is fixedly installed at both ends of the transmission rod 730. The two second bevel gears are respectively meshed with the two first bevel gears. Furthermore, a third bevel gear is installed on the drive shaft of the motor 720, and a fourth bevel gear is fixedly sleeved on the transmission rod 730. The third bevel gear and the fourth bevel gear are meshed.

[0025] See Figure 3 and 4 The protective platform body 60 includes a platform body 610. A connecting plate 620 is fixedly installed on one side wall of the platform body 610. Two rectangular blocks 510 are fixedly connected to the connecting plate 620. Several limiting rails 310 are fixedly installed at the bottom of the connecting seat 30. Limiting blocks 320 are slidably arranged in the several limiting rails 310. Connecting rods 330 are fixedly connected to the bottom of the several limiting blocks 320. One end of the several connecting rods 330 is connected to the side wall of the connecting plate 620. Specifically, the two rectangular blocks 510 drive the connecting plate 620 to move horizontally. At the same time, the connecting plate 620 drives the several connecting rods 330 to move horizontally, so that the connecting rods 330 drive the limiting blocks 320 to move horizontally within the limiting rails 310, thereby supporting the connecting plate 620 and further supporting the platform body 610.

[0026] See Figure 3 The limiting rail 310 has a T-shaped groove, and the limiting block 320 is T-shaped and slides in the T-shaped groove. By setting the T-shaped groove and setting the limiting block 320 in a T-shape, the limiting purpose of the limiting block 320 can be achieved, so that the limiting rail 310 supports the limiting block 320.

[0027] When using this bridge construction high-altitude operation safety protection platform: After workers enter the platform body 610 and take safety precautions, they can move the connecting seat 30 to one side of the bridge via the suspension device 20. The connecting seat 30 then moves the protective platform body 60 to the side of the bridge via the horizontal moving mechanism 50 to facilitate construction operations. When it is necessary to adjust the distance between the platform body 610 and the bridge, the motor 720 is started, which drives the transmission rod 730 to rotate. The transmission rod 730 then drives the two threaded rods 710 to rotate simultaneously, thereby driving the two sliders 520 to move synchronously. In turn, the two sliders 520 drive the two rectangular blocks 510 to move synchronously, causing the two rectangular blocks 510 to move the connecting plate 620 horizontally, thus moving the platform body 610 horizontally to facilitate the adjustment of the distance between the platform body 610 and the bridge.

[0028] It should be noted that the specific model specifications of the vehicle body 10, suspension device 20, motor 720 and platform body 610 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0029] The power supply and principles of the vehicle body 10, suspension device 20, and motor 720 are clear to those skilled in the art and will not be described in detail here.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
