Description

Technical Field

[0001] This utility model relates to tools used in building decoration engineering, and more particularly to a tool suitable for repairing the waterproof layer of anchor holes at the beam ends of railway box girders. Background Technology

[0002] The anchorages at the ends of railway box girders are critical components of prestressed bridge structures. Their waterproofing layer primarily prevents rainwater and moisture from seeping into the anchorages, avoiding corrosion of the prestressing tendons and anchorages, and ensuring structural safety and durability. When defects such as cracking, bulging, peeling, or leakage occur in the waterproofing layer, it must be repaired promptly.

[0003] During the repair of the waterproofing layer at the anchorages at both ends of the box girder, construction workers entered the box girder through pre-reserved manholes at the bridge ends. Once inside, they moved to the ends of the box girder to begin work. Because the pre-reserved manholes were small, large equipment could not enter. The gaps between the erected box girders were also small, typically only a few centimeters. Within these gaps, workers used angle grinders and other grinding equipment to grind the beam end faces, removing the original damaged waterproofing layer and exposing the fresh base layer. Waterproofing coating was then applied to the base layer surface using rollers and other tools. The entire construction process relied almost entirely on manual labor, resulting in high workload and low efficiency. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.

[0024] like Figure 1 The illustrated tool for repairing waterproofing layers in beam end anchorages includes: a trolley 1, a pump 2, a battery 4, a support rod 5, a grinding head drive motor 6, a grinding head 8, and a nozzle 9. The pump 2 and battery 4 are fixedly mounted on the trolley 1, and the battery 4 supplies power to the pump 2 and the grinding head drive motor 6.

[0025] The pump 2 is equipped with an inlet pipe 2-1 and an outlet pipe 2-2. A first connector 2-3 is located at the end of the outlet pipe 2-2. During use, a paint bucket is placed inside, and the end of the inlet pipe 2-1 is placed within the paint bucket to draw in the waterproof paint. The waterproof paint is pressurized by the pump 2 and then output through the outlet pipe 2-2. The outlet pipe 2-2 is used to connect to the spray head 9.

[0026] The grinding head 8 and the spray nozzle 9 are detachably connected to the upper connecting end 5-6 of the support rod 5. When grinding is performed, the grinding head 8 is installed at the upper connecting end 5-6 of the support rod 5. When spraying is performed, the spray nozzle 9 is installed at the upper connecting end 5-6 of the support rod 5.

[0027] This embodiment also includes a dust collection device and a blower device. The dust collection device is used to absorb dust generated during the grinding process, keeping the on-site construction environment clean. The blower device is used to dry the damp end face of the box girder for subsequent operations. Both the dust collection device and the blower device are powered by battery 4. In this embodiment, the dust collection device and the blower device are integrated suction and blowing machines 3. The integrated suction and blowing machine 3 is equipped with an air inlet 3-1, an air outlet 3-2, and an air duct 3-3. The air duct 3-3 is used for both dust collection and blowing. One end of the air duct is adapted to the air inlet 3-1 and the air outlet 3-2, and the other end is equipped with a second connector 3-4. One end of the air duct 3-3 can be connected to both the air inlet 3-1 and the air outlet 3-2 at the same time. Corresponding valves are installed at the connection points to control the opening and closing of the corresponding air passages. This avoids the need to switch the connection method of the air duct 3-3 during use, improving efficiency and saving time.

[0028] like Figure 2 As shown, the grinding head 8 includes a grinding disc 8-1, a suction shell 8-2, an end flexible shaft 8-3, an end air duct 8-4, a bracket 8-5, a third connector 8-6, and a third fixing plate 8-7. The suction shell 8-2 covers the grinding disc 8-1. The end flexible shaft 8-3 is connected to the grinding disc 8-1. The grinding disc 8-1 is mounted on the bracket 8-5. The upper end of the bracket 8-5 is hinged to the support device of the grinding disc, facilitating the grinding disc to swing within a certain range. The end air duct 8-4 communicates with the suction shell 8-2. The lower end of the bracket 8-5 is fixedly connected to the third fixing plate 8-7. The lower ends of the end flexible shaft 8-3 and the end air duct 8-4 are fixed on the third fixing plate 8-7. The third connector 8-6 is sleeve-shaped, and its top is provided with an inwardly extending limiting part to prevent the third fixing plate 8-7 from coming out. The third connector 8-6 is connected to the upper connecting end 5-6 by a thread.

[0029] like Figure 3 As shown, the nozzle 9 includes a nozzle body 9-1, a fourth fixing plate 9-2, and a fourth connector 9-3. The nozzle body 9-1 is fixed on the fourth fixing plate 9-2. The fourth connector 9-3 is sleeve-shaped, and its top is provided with an inwardly extending limiting part to prevent the fourth fixing plate 9-2 from coming out. The fourth connector 9-3 is connected to the upper connecting end 5-6 by a thread.

[0030] The overall thickness of the grinding head 8 and the spray head 9 does not exceed 7cm, so that they can be inserted into the gap between the end faces of the two box beams for grinding and spraying operations.

[0031] like Figure 1 and Figure 4As shown, the support rod 5 is provided with an inner flexible shaft 5-5, an inner paint tube 5-3, and an inner air duct 5-4. The lower connecting end 5-1 of the support rod 5 is provided with a branch pipe 5-2 and a spray switch 7. The lower ends of the inner paint tube 5-3 and the inner air duct 5-4 are located in the branch pipe 5-2. The spray switch 7 is used to control the on / off state of the inner paint tube 5-3.

[0032] The grinding head drive motor 6 is fixedly mounted on the support rod 5, and its output end is connected to the inner flexible shaft 5-5. The upper ends of the inner paint tube 5-3, the inner flexible shaft 5-5, and the inner air duct 5-4 are all located in the upper connecting end 5-6 of the support rod 5, and are respectively adapted to the end flexible shaft 8-3 and end air duct 8-4 of the nozzle 9 and the grinding head 8. As an optional implementation, without affecting the grinding head's ability to extend into the gap between the two box girders for operation, the grinding head drive motor 6 can be located at the upper end of the support rod 5 near the grinding head 8. The grinding head drive motor 6 can serve as a counterweight for the grinding head 8, making the upper end of the support rod 5 heavier overall, which facilitates applying force to the end face of the box girder during grinding. Alternatively, as... Figure 1 As shown, the grinding head drive motor 6 is installed at the lower end of the support rod 5, and a counterweight is set on the grinding head 8 to increase the weight of the grinding head 8. As a priority, the counterweight can be disassembled and replaced, making it easy to adjust the weight of the grinding head 8 and convenient for people with different scenarios or different operating habits.

[0033] When installing the grinding head 8 onto the upper connecting end 5-6 of the support rod 5, first align and insert the end flexible shaft 8-3 and the end air duct 8-4 with the inner flexible shaft 5-5 and the inner air duct 5-4 respectively. At this time, the third fixing plate 8-7 abuts against the upper connecting end 5-6 of the support rod 5. Then, tighten the third connector 8-6 onto the upper connecting end 5-6 to complete the fixed installation of the grinding head 8. The end air duct 8-4 and the inner air duct 5-4 are statically connected, and the connection should be as tight as possible to avoid air leakage. The end flexible shaft 8-3 and the inner flexible shaft 5-5 are connected to achieve power transmission, so the connection needs to be tight and secure to prevent relative rotation. Figure 2 and Figure 4 As shown, a triangular prism-shaped insertion end is provided at the lower end of the end flexible shaft 8-3, and a corresponding triangular prism-shaped insertion groove is provided at the upper end of the inner flexible shaft 5-5.

[0034] To enhance the stability of the grinding head 8 after installation, a plug-in structure can be installed between the third fixing plate 8-7 and the upper connecting end 5-6.

[0035] The first end of the duct 3-3 is connected to the air inlet 3-1 or the air outlet 3-2, and the second end of the duct 3-3 is provided with a second connector 3-4 adapted to the branch pipe 5-2, such as... Figure 6As shown, a second fixing plate 3-6 is provided inside the second connector 3-4. A second connecting pipe head 3-5 for connecting with the air duct 3-3 is fixedly provided on the second fixing plate 3-6. The second connecting pipe head 3-5 is adapted to the inner air duct 5-4 in the branch pipe 5-2. The second fixing plate 3-6 and the second connector 3-4 are rotatably arranged relative to each other. The second connector 3-4 is threadedly connected to the branch pipe 5-2.

[0036] During grinding operations, the first end of duct 3-3 is connected to the air inlet 3-1, and the second end is connected to the branch pipe 5-2. Dust generated during grinding enters the suction and blowing machine 3 through the suction housing 8-2, the end duct 8-4, the inner duct 5-4, and duct 3-3. When drying is required, the first end of duct 3-3 is connected to the air outlet 3-2, and air is blown onto the end face of the box girder through duct 3-3, the inner duct 5-4, the end duct 8-4, and the suction housing 8-2. Duct 3-3 is a corrugated pipe, configured with a sufficiently long length according to actual needs. When not in use, duct 3-3 can be coiled and tied to the trolley 1. As a further improvement, the blowing device is also equipped with an electric heating wire, enabling the blowing device to blow hot air. In cold seasons or regions, hot air can be used to dry the end face of the bridge, improving work efficiency.

[0037] like Figure 5 As shown, a first fixing plate 2-5 is provided inside the first connector 2-3. A first connecting pipe head 2-4 for connecting with the feed pipe 2-1 is fixedly provided on the first fixing plate 2-5. The first connecting pipe head 2-4 is adapted to the inner coating pipe 5-3 inside the branch pipe 5-2. The first fixing plate 2-5 and the first connector 2-3 are rotatably arranged relative to each other. The first connector 2-3 is threadedly connected to the branch pipe 5-2.

[0038] During spraying operations, a nozzle 9 is installed at the upper connecting end of the support rod 5, and the branch pipe 5-2 is connected to the first connector 2-3. The waterproof coating is conveyed to the nozzle 9 through the discharge pipe 2-2 and the inner coating pipe 5-3 to achieve the spraying of the waterproof coating. The discharge pipe 2-2 is a high-pressure pipe, and its length can be configured to be sufficient according to the actual construction situation. When not in use, the discharge pipe 2-2 can be coiled up and fixed on the trolley 1.

[0039] like Figure 1As shown, this embodiment also includes at least one extension rod 11. The extension rod 11 includes an outer rod 11-1, an inner rod 11-2 fitted inside the outer rod 11-1, and a latch 11-3 located at the end of the outer rod 11-1 for fixing the inner rod 11-2. After the latch 11-3 is opened, the inner rod 11-2 can extend and retract within the outer rod 11-1 to adjust the length of the extension rod 11. After adjustment, the position of the inner rod 11-2 is fixed by the latch 11-3. The top end of the inner rod 11-2 is detachably connected to the lower connecting end 5-1 of the support rod 5. Multiple extension rods 11 can be connected end to end to achieve overall lengthening of the support rod 5. Preferably, with the extension rods 11 provided, the total length of the support rod can reach 4-5 meters, which can easily cover different positions on the end face of the box girder.

[0040] like Figure 1 As shown, in this embodiment, the trolley 1 includes a base plate 1-1, on which a support frame 1-2 is also provided. The pump 2 is fixedly mounted on the base plate 1-1, and the suction and blowing integrated machine 3 is fixedly mounted on the support frame 1-2.
