Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge maintenance technology, and in particular to a cleaning device for bridge steel expansion joints. Background Technology
[0002] Bridge expansion joints are an important component of bridge design. Expansion joints accommodate the relative movement of the bridge deck caused by temperature changes and vehicle loads, allowing bridge components to maintain a constant state during expansion and contraction. However, expansion joints are prone to accumulating particles or debris, especially in areas with sparse vegetation and high wind and sand levels. This debris can affect the usability of the expansion joints, necessitating regular cleaning.
[0003] Currently, the main method for cleaning expansion joints is to manually remove particles, dirt, and impurities. However, since expansion joints are located at the bottom of bridges and the space inside is dark, it is not convenient to clean the materials inside. Furthermore, it is difficult to remove tightly adhered materials from the expansion joints. Therefore, a bridge steel expansion joint cleaning device is needed to meet the usage requirements. Utility Model Content
[0004] The purpose of this invention is to provide a bridge steel expansion joint cleaning device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a bridge steel expansion joint cleaning device, comprising a handle, an adjustable length adjustment rod disposed within the handle, an anti-detachment handle fixedly installed at the tail end of the handle, a length locking mechanism disposed on the handle and the length adjustment rod, a cleaning plate angle adjustment mechanism disposed at the bottom end of the length adjustment rod, a cleaning plate disposed on the cleaning plate angle adjustment mechanism, an adjustable shovel disposed on the cleaning plate, a shovel fixing mechanism disposed on the cleaning plate and the shovel, and a cleaning lighting mechanism disposed on the length adjustment rod.
[0006] Preferably, the length locking mechanism includes a length locking screw groove formed on the grip and the length adjusting rod, and a length locking bolt is screwed into the length locking screw groove.
[0007] Preferably, the shovel fixing mechanism includes a rotating plate fixedly installed at the bottom end of the length adjusting rod, a support block fixedly installed on the cleaning plate, a damping adjusting screw screw screwed into the support block, and the rotating plate rotatably installed on the damping adjusting screw screw.
[0008] Preferably, the blade fixing mechanism includes fixing screw grooves formed on the cleaning plate and the blade, and fixing bolts are screwed into the fixing screw grooves.
[0009] Preferably, the cleaning lighting mechanism includes a rotating ring rotatably fitted onto the cleaning plate angle adjustment mechanism, and the rotating ring is provided with a main lighting lamp, a side photo lamp, and a battery.
[0010] Preferably, a drive motor is fixedly installed on the cleaning plate angle adjustment mechanism, a drive gear is fixedly installed at the output end of the drive motor, and a driven gear is rotatably sleeved on the cleaning plate angle adjustment mechanism, with the driven gear meshing with the drive gear.
[0011] Preferably, a first retaining ring and a second retaining ring are fixedly sleeved on the cleaning plate angle adjustment mechanism. The first retaining ring is distributed on the upper and lower sides of the rotating ring, and the second retaining ring is distributed on the upper and lower sides of the driven gear.
[0012] The beneficial effects of this utility model are:
[0013] In this invention, the cleaning plate, scraper, cleaning plate angle adjustment mechanism, and scraper fixing mechanism are designed to extend the cleaning plate into the expansion joint and remove particles, dirt, or impurities from the gap. If stubborn substances are stuck in the expansion joint, the scraper is mounted on the fixing screw groove at the lower position using fixing bolts. The scraper then extends beyond the cleaning plate, allowing for the removal and scraping of stubborn substances, resulting in a better cleaning effect on the expansion joint.
[0014] In this invention, by setting up structures such as a cleaning lighting mechanism, a length adjustment rod, and a length locking mechanism, the main lighting lamp and the side photo lamp illuminate the space inside the expansion joint, making it easier to observe the expansion joint. The rotation of the drive motor drives the main lighting lamp and the side photo lamp to rotate, thereby allowing adjustment of the direction and angle of illumination, making it easier to observe different areas inside the expansion joint. Pulling the length adjustment rod in the handle can adjust the length of the device. After adjustment, the length locking bolt is screwed into the length locking screw groove to fix the length of the device. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Example:
[0022] like Figure 1-4 As shown, this embodiment provides a bridge steel expansion joint cleaning device, including a handle 1, an adjustable length adjustment rod 2 inside the handle 1, an anti-detachment handle 3 fixedly installed at the tail end of the handle 1, a length locking mechanism 4 on the handle 1 and the length adjustment rod 2, a cleaning plate angle adjustment mechanism 5 at the bottom end of the length adjustment rod 2, a cleaning plate 6 on the cleaning plate angle adjustment mechanism 5, a scraper 7 adjustablely mounted on the cleaning plate 6, a scraper fixing mechanism 8 on the cleaning plate 6 and the scraper 7, and a cleaning lighting mechanism 9 on the length adjustment rod 2;
[0023] By gripping the device with the handle 1, the anti-slip handle 3 prevents the device from slipping out of your hand. Then, insert the cleaning plate 6 into the expansion joint and use it to remove particles, dirt, or impurities from the gap. The scraper 7 can be mounted on the cleaning plate 6 via the scraper fixing mechanism 8, allowing for the removal of stubborn substances and providing good cleaning results for the expansion joint. The length of the device can be adjusted by pulling the length adjustment rod 2 within the handle 1, and the length is fixed by the length locking mechanism 4. When cleaning the expansion joint, the cleaning lighting mechanism 9 illuminates the space inside the expansion joint for easy observation. The cleaning plate angle adjustment mechanism 5 adjusts the grip angle of the handle 1 and the length adjustment rod 2, allowing for adjustments based on usage conditions and facilitating use by cleaning personnel.
[0024] In this embodiment of the utility model, specifically, the length locking mechanism 4 includes a length locking screw groove 41 opened on the handle 1 and the length adjusting rod 2, and a length locking bolt 42 is screwed into the length locking screw groove 41;
[0025] To fix the adjusted length of the device, the length adjustment rod 2 can be pulled out of the handle 1 to adjust the length of the device. After adjustment, the length locking bolt 42 is screwed into the length locking screw groove 41 to fix the length of the device.
[0026] In this embodiment of the utility model, specifically, the shovel fixing mechanism 8 includes a rotating plate 52 fixedly installed at the bottom end of the length adjusting rod 2, a support block 51 fixedly installed on the cleaning plate 6, a damping adjusting screw 53 screwed into the support block 51, and the rotating plate 52 rotatably installed on the damping adjusting screw 53.
[0027] To adjust the angle of the cleaning plate 6, the rotating plate 52 rotates within the damping adjusting screw 53 to adjust the grip angle of the handle 1 and the length adjusting rod 2. This can be adjusted according to usage conditions, facilitating use by cleaning personnel. Rotating the hexagonal screw block at the end of the damping adjusting screw 53 causes the damping adjusting screw 53 to rotate. The rotation of the damping adjusting screw 53 pulls a set of support blocks 51 closer together. The slight deformation of the support blocks 51 allows them to rest against both sides of the rotating plate 52, thereby adjusting the rotation damping of the cleaning plate 6, maintaining the state of the cleaning plate 6, and facilitating the removal of materials from the expansion joint.
[0028] In this embodiment of the utility model, specifically, the shovel fixing mechanism 8 includes a fixing screw groove 81 formed on the cleaning plate 6 and the shovel 7, and a fixing bolt 82 is screwed into the fixing screw groove 81;
[0029] To remove tightly adhered materials, if there are stubborn materials adhering to the expansion joint, the scraper 7 is installed on the fixing screw groove 81 at the lower position using the fixing bolt 82. At this time, the scraper 7 extends out of the cleaning plate 6, and the stubborn materials can be scraped off and removed by the scraper 7, which has a better cleaning effect on the expansion joint.
[0030] In this embodiment of the utility model, specifically, the cleaning lighting mechanism 9 includes a rotating ring 91 rotatably sleeved on the cleaning plate angle adjustment mechanism 5, and the rotating ring 91 is provided with a main lighting lamp 92, a side photo lamp 93 and a battery 94;
[0031] To facilitate observation of the material to be cleaned within the expansion joint, the rotating ring 91 rotates, causing the main lighting 92 and side photographic light 93 to rotate as well. This allows for adjustment of the direction and angle of illumination from the main lighting 92 and side photographic light 93, making it easier to observe different areas within the expansion joint. The battery 94 provides power to the main lighting 92 and side photographic light 93 during use, eliminating the need for an external power source and making it convenient to use.
[0032] In this embodiment of the utility model, a drive motor 96 is fixedly installed on the cleaning plate angle adjustment mechanism 5, a drive gear 97 is fixedly installed on the output end of the drive motor 96, and a driven gear 95 is rotatably sleeved on the cleaning plate angle adjustment mechanism 5, with the driven gear 95 and the drive gear 97 meshing with each other.
[0033] To drive the main lighting lamp 92 and the side photo lights 93 to rotate, the drive motor 96 rotates, which drives the drive gear 97 to rotate. The drive gear 97 rotates, which drives the driven gear 95 to rotate. The driven gear 95 rotates, which drives the rotating ring 91 to rotate. The rotating ring 91 rotates, which drives the main lighting lamp 92 and the side photo lights 93 to rotate, thus providing a power source for the rotation of the main lighting lamp 92 and the side photo lights 93.
[0034] In this embodiment of the utility model, a first retaining ring 98 and a second retaining ring 99 are fixedly sleeved on the cleaning plate angle adjustment mechanism 5. The first retaining ring 98 is distributed on the upper and lower sides of the rotating ring 91, and the second retaining ring 99 is distributed on the upper and lower sides of the driven gear 95.
[0035] To limit the rotation ring 91 and driven gear 95, a first retaining ring 98 and a second retaining ring 99 can limit the rotation ring 91 and driven gear 95 to prevent them from sliding on the cleaning plate angle adjustment mechanism 5.
[0036] Working principle: In use, hold the device with the handle 1; the anti-slip handle 3 prevents the device from slipping out of your hand. Then, insert the cleaning plate 6 into the expansion joint and use it to remove particles, dirt, or impurities from the gap. If there are stubborn substances stuck in the expansion joint, install the scraper 7 on the low-position fixing screw groove 81 using the fixing bolt 82. At this time, the scraper 7 extends out of the cleaning plate 6 and can be used to scrape and remove the stubborn substances, resulting in a better cleaning effect on the expansion joint. Pulling the length adjustment rod 2 inside the handle 1 can adjust the length of the device. After adjustment, screw the length locking bolt 42 into the length locking screw groove 41 to fix the length of the device. When cleaning the expansion joint, the main light 92 and the side photo light 93 illuminate the space inside the expansion joint, making it easier to observe the expansion joint. The rotation of the drive motor 96 drives the drive gear 97 to rotate, which in turn drives the driven gear 95 to rotate. The rotation of the driven gear 95 drives the rotating ring 91 to rotate, which in turn drives the main light 92 and the side photo light 93 to rotate. The direction and angle of the main light 92 and the side photo light 93 can be adjusted to facilitate the observation of different areas inside the expansion joint. The battery 94 can power the main light 92 and the side photo light 93 when they are in use, eliminating the need for an external power source and making it more convenient to use. The first retaining ring 98 and the second retaining ring 99 can limit the rotation ring 91 and the driven gear 95 to prevent them from sliding on the cleaning plate angle adjustment mechanism 5. The rotating plate 52 can adjust the angle of the cleaning plate 6 by rotating within the damping adjusting screw 53. It can be adjusted according to the usage conditions to facilitate the use of cleaning personnel. Rotating the hexagonal screw block at the end of the damping adjusting screw 53 can drive the damping adjusting screw 53 to rotate. The rotation of the damping adjusting screw 53 will pull a set of support blocks 51 to move closer to each other. The slight deformation of the set of support blocks 51 can abut against both sides of the rotating plate 52, thereby adjusting the rotation damping of the cleaning plate 6, maintaining the state of the cleaning plate 6, and facilitating the removal of materials in the expansion joint.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
