Description

Technical Field

[0001] This utility model belongs to the field of bridge construction technology, specifically, it relates to a bridge bearing pad stone grinding device. Background Technology

[0002] Bridge bearing pads, located between the top of the pier and the bridge bearing, are typically rectangular or square blocks cast on-site at the top of the pier using high-strength concrete. They are used to effectively distribute and transfer the loads from the bearing and the superstructure beams to the substructure, provide a precise installation platform for the bridge bearings, and adjust the elevation and level of the top surface of the pier. Therefore, the flatness and levelness of the top surface of the bearing pad have a crucial impact on the stability and service life of the bridge. If the top surface of the bearing pad is uneven or not level, it will lead to uneven stress on the bridge bearing, accelerate the damage of the bearing, and thus affect the structural safety of the bridge.

[0003] The flatness of the top surface of the bearing pad stone cast on site usually cannot directly meet the installation requirements of bridge bearings. Therefore, it is necessary to perform secondary leveling on the top surface of the bearing pad stone. In the existing technology, most of the leveling is done by manually grinding with hand-held grinding tools. This method is labor-intensive and has low grinding efficiency. In addition, the existing grinding equipment has insufficient installation stability between the bearing pad stone and the bearing pad stone, which makes it difficult to ensure the flatness and levelness of the top surface of the bearing pad stone. Utility Model Content

[0004] To solve or partially solve the problems existing in related technologies, this utility model provides a bridge bearing pad stone grinding device, which aims to solve the problems of high labor intensity and low grinding efficiency in the existing bearing pad stone top surface grinding and leveling methods, as well as the difficulty in ensuring the flatness and levelness of the bearing pad stone top surface.

[0005] This application provides a bridge bearing pad stone grinding device, including a base, a pole, a base, a two-dimensional manipulator, and a grinding head;

[0006] The base has a vertically penetrating receiving groove, the support pad is located in the receiving groove, and several horizontally adjustable pillars are installed at the bottom of the base. The vertical installation height of the horizontally adjustable pillars on the base is adjustable by means of threads. Clamping bolts that penetrate the side wall of the base and extend to the receiving groove are horizontally installed on the front and rear sides of the base. The horizontal installation position of the clamping bolts on the base is adjustable by means of threads.

[0007] The upright is fixedly mounted on the base, and the base is vertically and height-adjustably inserted through the upright. A two-dimensional robotic arm is mounted on the base, and a grinding head is driven on the two-dimensional robotic arm.

[0008] In one alternative, a rack is vertically fixed to one side of the upright, and a transmission rod is rotatably threaded through the base on the side corresponding to the rack, the transmission rod having gear teeth that mesh with the rack.

[0009] In one alternative, a locking bolt is horizontally installed on one side of the base, penetrating the side wall of the base, and the locking bolt can be tightened against the side of the upright.

[0010] In one alternative, a height gauge is provided on one side of the pole.

[0011] In one alternative, a base level indicator bubble is provided on the base, and a robotic arm level indicator bubble is provided on the two-dimensional robotic arm.

[0012] In one alternative, a pad is fixedly installed at the bottom of the leveling support.

[0013] In one alternative, a clamping plate is fixedly installed at the end of the clamping bolt facing the support pad stone.

[0014] The beneficial effects of this utility model are:

[0015] This invention adjusts the levelness of the base by adjusting the vertical installation height of the horizontal adjustment column on the base, ensuring the levelness of the base and thus effectively improving the levelness of the grinding head on the grinding surface of the support stone. The base is clamped and fixed to the support stone using clamping bolts, eliminating the need for drilling holes in the support stone and avoiding damage to its structure. This also effectively improves the installation stability between the device and the support stone, reducing grinding errors caused by equipment movement and thus improving the grinding performance on the top surface of the support stone. The grinding quality is excellent; the grinding height can be adaptively adjusted by changing the vertical installation height of the base on the upright according to the construction requirements of the top surface of the bearing pad stone. This effectively improves the applicability of the device and can meet the needs of various construction scenarios. The grinding head is driven by a two-dimensional robotic arm to complete the grinding action, which can fully cover the top surface of the bearing pad stone for grinding. This effectively improves the flatness of the grinding head on the bearing pad stone, thereby ensuring the flatness and levelness of the top surface of the bearing pad stone after grinding. The flatness and levelness of the top surface of the bearing pad stone can meet the construction requirements. It saves time and labor, has high grinding efficiency, and produces good grinding quality.

[0028] The existing methods for grinding and leveling the top surface of bearing pad stones have problems such as high labor intensity, low grinding efficiency, and difficulty in ensuring the flatness and levelness of the top surface of the bearing pad stones.

[0029] To address the aforementioned problems, this application proposes improvements and innovations, including the following embodiments.

[0030] In some implementations, please refer to Figures 1-4 This application provides a bridge bearing pad stone grinding device, including a base 1, a pole 2, a base 3, a two-dimensional manipulator 4, and a grinding head 5; the base 1 has a vertically penetrating receiving groove 101, the bearing pad stone 100 is located in the receiving groove 101, three horizontal adjustment pillars 6 are installed at the bottom of the base 1, the vertical installation height of the horizontal adjustment pillars 6 on the base 1 is adjustable by means of threads, and two clamping bolts 7 are horizontally installed on the front and rear sides of the base 1 respectively, penetrating the side wall of the base 1 and extending to the receiving groove 101, the horizontal installation position of the clamping bolts 7 on the base 1 is adjustable by means of threads.

[0031] The upright 2 is vertically fixed on the base 1. The base 3 is vertically and height-adjustably inserted through the upright 2. A two-dimensional robot 4 is installed on the base 3. A grinding head 5 is driven and installed on the two-dimensional robot 4. The two-dimensional robot 4 includes a large robot arm and a small robot arm. The large robot arm is rotatably installed on the base 3, and the small robot arm is rotatably installed on the large robot arm. A power device for driving the grinding head 5 is provided in the small robot arm. The grinding head 5 is driven and connected to the power device. Specifically, the two-dimensional robot 4 is a known technology, and its specific structure and principle will not be described in detail.

[0032] Specifically, when it is necessary to grind the top surface of the bearing pad 100, first place this device on the top of the pier so that the bearing pad 100 to be ground is located in the receiving groove 101. Then adjust the vertical installation height of the horizontal adjustment column 6 on the base 1 to adjust the levelness of the base 1. Then tighten the clamping bolt 7 to clamp the bearing pad 100 so that the base 1 and the bearing pad 100 are tightly fixed. Then, according to the construction requirements of the top surface height of the bearing pad 100, adjust and lock the vertical installation height of the base 3 on the upright 2. Finally, drive the grinding head 5 through the two-dimensional robot 4 to grind the top surface of the bearing pad 100.

[0033] Thus, in this embodiment, the levelness of the base 1 can be adjusted by adjusting the vertical installation height of the horizontal adjustment column 6 on the base 1, ensuring the levelness of the base 1 and effectively improving the levelness of the grinding head 5 on the grinding surface of the support stone 100. The base 1 can be clamped and fixed to the support stone 100 by the clamping bolts 7, eliminating the need to drill holes in the support stone 100 to fix the device to it, avoiding damage to the structure of the support stone 100. This also effectively improves the installation stability between the device and the support stone 100, effectively reducing grinding errors caused by equipment movement, and thus effectively improving... The grinding quality of the top surface of the bearing pad 100 is improved by adjusting the vertical installation height of the base 3 on the upright 2 according to the construction requirements of the top surface height of the bearing pad 100. This effectively improves the applicability of the device and meets the needs of various construction scenarios. The grinding head 5 is driven by the two-dimensional robot arm 4 to complete the grinding action, which can fully cover the top surface of the bearing pad 100 for grinding. This effectively improves the flatness of the grinding surface of the bearing pad 100 formed by the grinding head 5, thereby ensuring the flatness and levelness of the top surface of the bearing pad 100 after grinding. The flatness and levelness of the top surface of the bearing pad 100 can meet the construction requirements, saving time and effort, with high grinding efficiency and good grinding quality.

[0034] In some embodiments, a rack 8 is vertically fixedly installed on the right side of the upright 2, and a transmission rod 9 is rotatably passed through the base 3 on the side corresponding to the rack 8. The transmission rod 9 is constructed with gear teeth that mesh with the rack 8. Specifically, the base 3 is slidably installed on the upright 2, and a cavity is opened inside the base 3 at the position corresponding to the rack 8 and the gear teeth to provide space for the installation and operation of the gear teeth and the rack 8. In this embodiment, a locking bolt 10 is horizontally installed on the rear side of the base 3, which penetrates the side wall of the base 3 and can be tightened against the side of the upright 2.

[0035] Thus, when adjusting the vertical installation height of the base 3 on the upright 2, on the one hand, the meshing of the gear teeth and the rack 8 makes the up-and-down sliding motion of the base 3 on the upright 2 stable and smooth, with high height adjustment accuracy and convenient adjustment; on the other hand, after the installation height of the base 3 is adjusted to the predetermined height, the locking bolt 10 can be tightened to press the rear side of the upright 2, thereby fixing the base 3 to the upright 2 at the predetermined height.

[0036] In some embodiments, a height scale 11 is provided on the front side of the upright 2. In this way, the scale on the height scale 11 can provide a reference for the vertical installation height adjustment operation of the base 3 on the upright 2, which can effectively improve the vertical installation height adjustment accuracy and efficiency of the base 3.

[0037] In some embodiments, a base level indicator bubble 12 is provided on the base 1, and a robotic arm level indicator bubble 13 is provided on the two-dimensional robotic arm 4. In this way, when adjusting the level of the base 1 by the level adjustment pillar 6, the base level indicator bubble 12 and the robotic arm level indicator bubble 13 can provide a real-time reference for adjusting the level of the base 1, making the adjustment convenient and effectively improving the adjustment efficiency.

[0038] In some embodiments, a pad 14 is fixedly installed at the bottom of the horizontal adjustment column 6. In this way, the contact area between the horizontal adjustment column 6 and the top surface of the pier is effectively increased by the pad 14, thereby effectively improving the support stability of the horizontal adjustment column 6 and the pad 14 on the base 1.

[0039] In some embodiments, a clamping plate 15 is fixedly installed on the end of the clamping bolt 7 facing the support pad 100. In this way, the clamping plate 15 effectively increases the contact area between the clamping bolt 7 and the side of the support pad 100, thereby effectively improving the clamping stability between the clamping bolt 7 and the support pad 100, thus improving the installation stability between the base 1 and the support pad 100. At the same time, it can effectively prevent damage to the side of the support pad 100 caused by stress concentration when the clamping bolt 7 and the support pad 100 are tightened.

[0040] Finally, it should be noted that although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, all of which should be included within the protection scope of this application.
