Description

Technical Field

[0001] This invention relates to the field of road construction, and in particular to a device and method for cleaning impurities in the expansion joints of multi-directional displacement comb plates. Background Technology

[0002] Expansion joints are structural joints installed at appropriate locations to prevent cracks or damage to bridges or roads due to changes in climate and temperature. Expansion joints are usually equipped with expansion devices to limit the expansion and contraction of bridges and roads.

[0003] Chinese patent CN109629408A discloses a double-slit comb plate expansion joint, including a central movable comb plate and two fixed comb plates. The two fixed comb plates are arranged on both sides of the central movable comb plate, and the comb teeth on the central movable comb plate and the fixed comb plates are staggered.

[0004] During installation, a cavity remains between the central movable comb plate and the comb teeth on the fixed comb plate. This allows debris such as stones from the road surface to enter the cavity, affecting the extension and retraction of the central movable comb plate. Therefore, workers need to periodically remove the debris from the cavity. Removing the debris usually involves manual cleaning of each cavity one by one, which is both labor-intensive and time-consuming. Summary of the Invention

[0005] To save labor and time spent cleaning impurities between comb plates, this application provides an impurity cleaning device and method for the expansion joint of multi-directional displacement comb plates.

[0006] Firstly, the impurity cleaning device for the expansion joint of a multi-directional displacement comb plate provided in this application adopts the following technical solution:

[0007] A device for cleaning impurities in the expansion joint of a multi-directional displacement comb plate includes a concrete base, a central movable comb plate and a fixed comb plate, both of which are set on the concrete base. The concrete base has a receiving cavity, and the receiving cavity is provided with a bearing mechanism for carrying impurities entering the cavity and a lifting mechanism for driving the bearing mechanism to move up and down.

[0008] The bearing mechanism includes a bearing plate with multiple bearing parts. Each bearing part has a cavity corresponding to a bearing part. Each bearing part includes two fixed blocks connected to the bearing plate. A sliding rod is provided between the two fixed blocks. Two bearing arms are slidably sleeved on the sliding rod. A compression spring is supported between the two bearing arms. The bearing arms extend into the corresponding cavities. An elastic bearing cover is sleeved between the tops of the two bearing arms. The elastic bearing cover abuts against the side wall of the corresponding cavity relative to the central movable comb plate and the fixed comb plate.

[0009] By adopting the above technical solution, the two support arms, under the support of the compression springs, open the elastic support cover and support the side walls of the central movable comb plate and the fixed comb plate. Thus, impurities entering the cavity will accumulate on the elastic support cover. Cleaning personnel can raise and lower the support mechanism using a lifting mechanism, thereby allowing the elastic support cover to gradually push the impurities out of the cavity. Afterwards, cleaning personnel can quickly sweep away the impurities on the elastic support cover, and then reset the support mechanism using the lifting mechanism. This application, through the cooperation of the lifting mechanism and the support mechanism, facilitates the quick removal of impurities by cleaning personnel, thereby saving labor and time.

[0010] Optionally, the lifting mechanism includes lifting parts respectively disposed at both ends of the bearing plate. Each lifting part includes a bearing seat disposed at the curb. A vertically arranged lead screw is inserted into the bearing seat. A wheel is connected to the top of the lead screw. The end of the bearing plate is threadedly connected to the lead screw.

[0011] By employing the above technical solution, two workers cooperate to synchronously rotate two lead screws in the forward direction. Under the action of the lead screws, the bearing plate moves upward, thereby ejecting impurities. Subsequently, the two lead screws are rotated synchronously in the reverse direction, causing the bearing plate to descend and reset.

[0012] Optionally, a synchronizing sprocket is fixedly fitted on each of the two lead screws, and a synchronizing chain is fitted between the two synchronizing sprockets.

[0013] By adopting the above technical solution, the cooperation of the synchronous chain and the synchronous sprocket enables the two lead screws to rotate synchronously, thereby improving the levelness of the bearing plate. This helps to reduce the possibility that the bearing plate will tilt due to the speed difference between the two lead screws, making it difficult for the bearing part to move up and down in the cavity.

[0014] Optionally, the fixing block has a blind hole on the side opposite to the sliding rod for the end of the sliding rod to be inserted, and the fixing block is detachably connected to the support plate.

[0015] By adopting the above technical solution, when the elastic support cover is damaged, cleaning personnel can replace the entire support component by disassembling the fixing block. Simultaneously, through the insertion and engagement of the sliding rod and the fixing block, cleaning personnel can also partially replace only the support component and the elastic support cover.

[0016] Optionally, a solar generator is installed on the curb, and the battery of the solar generator is electrically connected to an electrical pin. The electrical pin is set on a fixed comb plate, and a conductive post is set on the support plate. A light bulb is electrically connected to the conductive post. When the electrical pin contacts the conductive post, the light bulb lights up.

[0017] By adopting the above technical solution, the solar generator supplies power to the conductive column. When the conductive column contacts the electrical pin, the bulb lights up. At this time, the upper surface of the elastic support cover is exactly flush with the upper surfaces of the central movable comb plate and the fixed comb plate, which helps to reduce the possibility of the elastic support cover protruding from the cavity and causing inconvenience to cleaning personnel in removing impurities.

[0018] Optionally, a protective box is provided at the curb, with one lifting unit corresponding to one protective box, and the lifting unit is located inside the corresponding protective box.

[0019] By adopting the above technical solution, the protective box can protect the lifting part, which helps to reduce the possibility of passers-by operating the impurity cleaning device at will.

[0020] Optionally, the concrete base layer is provided with multiple support strips at a position relative to the bottom of the cavity. The support strips slide through the bearing plate and are supported on the lower surface of the comb teeth on the central movable comb plate and the fixed comb plate.

[0021] By adopting the above technical solution, the support bar can support the comb teeth on the central movable comb plate and the fixed comb plate, reducing the possibility that the comb teeth on the central movable comb plate and the fixed comb plate will bend and deform into the cavity under the action of vehicle gravity.

[0022] Secondly, this application provides a cleaning method for a multi-directional displacement comb plate expansion joint impurity cleaning device, which adopts the following technical solution:

[0023] A cleaning method for a multi-directional displacement comb plate expansion joint impurity cleaning device includes the following steps:

[0024] S1. Set up roadblocks: Set up warning roadblocks on both sides of the expansion joint of the multi-directional displacement comb plate;

[0025] S2, Lifting and Cleaning: Two workers cooperate to rotate the screw in the forward direction, thereby lifting the bearing mechanism and pushing out the impurities in the cavity. When the light bulb just lights up, the screw is stopped, and the workers quickly clean up the impurities.

[0026] S2. Reset and remove the obstacle: Two workers work together to rotate the screw in opposite directions, causing the load-bearing mechanism to descend and reset. Then, the warning obstacle is quickly removed.

[0027] By adopting the above technical solution, warning barriers are set up to alert drivers, thereby improving the safety of cleaning personnel during the cleaning process. Two cleaning workers work together to rotate the lead screw in unison, causing the elastic support cover to move upward, which pushes out the impurities in the cavity, allowing the cleaning personnel to quickly sweep them away. Subsequently, rotating the lead screw in the opposite direction causes the elastic support cover to descend and reset, allowing the cleaning personnel to remove the warning barriers. In this way, impurities can be quickly removed, saving labor and time.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. Cleaning personnel use a lifting mechanism to raise and lower the supporting structure. This allows the elastic support cover to gradually push impurities out of the cavity, after which cleaning personnel can quickly remove the impurities from the elastic support cover. The coordination between the lifting and supporting mechanisms facilitates rapid removal of impurities, thus saving labor and time.

[0030] 2. The solar generator supplies power to the conductive column. When the conductive column contacts the electrical pin, the bulb lights up. At this time, the upper surface of the elastic support cover is flush with the upper surfaces of the central movable comb plate and the fixed comb plate, which helps to reduce the possibility of the elastic support cover protruding from the cavity and causing inconvenience to cleaning personnel in removing impurities.

[0036] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0037] This application discloses an impurity cleaning device for the expansion joint of a multi-directional displacement comb plate.

[0038] Reference Figure 1The impurity cleaning device for the expansion joint of the multi-directional displacement comb plate includes a concrete base layer, a central movable comb plate 2 and a fixed comb plate 3, both of which are detachably connected to the concrete base layer 1 in accordance with the prior art.

[0039] Reference Figure 1 and Figure 2 The concrete base layer 1 has an opening for receiving cavity 101 at the position where the comb teeth of the central movable comb plate 2 and the fixed comb plate 3 intersect. The receiving cavity 101 is parallel to the length direction of the expansion joint. The receiving cavity 101 is equipped with a bearing mechanism for carrying impurities entering the cavity and a lifting mechanism for driving the bearing mechanism to move up and down.

[0040] Reference Figure 1 and Figure 2 The bearing mechanism includes a bearing plate 41 and multiple bearing parts. The bearing plate 41 is horizontally arranged and parallel to the length direction of the receiving cavity 101. The bearing parts are located on the upper surface of the bearing plate 41, and one bearing part corresponds to one cavity.

[0041] Because of the presence of the receiving cavity 101, the positions where the comb teeth on the central movable comb plate 2 and the fixed comb plate 3 intersect are suspended in the air. Therefore, the comb teeth may deform into the receiving cavity 101 due to the gravity of the vehicle, which may have an adverse effect on the normal driving of the vehicle.

[0042] For this purpose, multiple support strips 9 are integrally formed on the concrete base layer 1 relative to the bottom of the cavity 101, and the bearing plate 41 is slidably sleeved on the support strips 9. Each support strip 9 corresponds to one comb tooth, and the top surface of the support strip 9 is supported on the lower surface of the corresponding comb tooth.

[0043] Reference Figure 2 and Figure 3 The bearing part includes two fixing blocks 42 and a sliding rod 43 bolted to the bearing plate 41. The side walls of the two fixing blocks 42 are respectively opened with blind holes 421. The sliding rod 43 is located between the two fixing blocks 42 and its end is inserted into the blind hole 421.

[0044] The bearing part also includes two bearing arms 44 that are slidably sleeved on the sliding rod 43, and a compression spring 45 that supports the two bearing arms 44. The compression spring 45 is sleeved on the sliding rod 43.

[0045] Two support arms 44 extend vertically upward into the corresponding cavities. An elastic support cover 46 is fitted between the top of the two support arms 44 and the arm body located in the cavity. The elastic support cover 46 is bonded to the support arms 44.

[0046] Under the action of the compression spring 45, the two bearing arms 44 cooperate to open the elastic bearing cover 46, and the bearing arms 44 press the elastic bearing cover 46 against the side wall of the corresponding cavity relative to the central movable comb plate 2 and the fixed comb plate 3.

[0047] When the central movable comb plate 2 moves, it pushes the bearing arm 44 to slide on the sliding rod 43, and the elastic bearing cover 46 undergoes a certain deformation.

[0048] During this process, the elastic bearing cover 46 remains in close contact with the central movable comb plate 2 and the fixed comb plate 3 corresponding to the cavity. After stones and other impurities on the road surface enter the cavity, they fall onto the elastic bearing cover 46.

[0049] Reference Figure 2 and Figure 3 When impurities enter the cavity, they exert pressure on the elastic bearing cover 46 under the action of the vehicle wheels, causing the top of the elastic bearing cover 46 to deform. When the impurities are sharp, the elastic bearing cover 46 is more easily damaged.

[0050] Therefore, by bolting the fixing block 42 to the bearing plate 41, the worker can replace the entire individual bearing component. In addition, the insertion and engagement of the fixing block 42 with the sliding rod 43 allows the worker to partially replace only the two bearing arms 44 and the elastic bearing cover 46.

[0051] Reference Figure 2 and Figure 4 The lifting mechanism includes lifting parts respectively disposed at both ends of the bearing plate 41. The lifting part includes a bearing seat 51 disposed at the curb by an expansion bolt. A vertically disposed lead screw 52 is disposed inside the bearing seat 51. A rotating wheel 53 is fixedly connected to the top end of the lead screw 52. The end of the bearing plate 41 is threadedly connected to the lead screw 52.

[0052] Two workers work together to rotate the two lead screws 52 in sync. The bearing plate 41 drives the bearing part to rise, so that the elastic bearing cover 46 can push the impurities in the cavity upward, thus making it easier for the operator to quickly clean the impurities.

[0053] Reference Figure 2 and Figure 4 Two lead screws 52 are respectively fixedly fitted with synchronous sprockets (not shown in the figure), and a synchronous chain 6 is fitted between the two synchronous sprockets. The synchronous chain 6 is located below the bearing plate 41.

[0054] By cooperating with the synchronous sprocket and the synchronous chain 6, synchronous rotation between the two lead screws 52 is achieved, reducing the possibility that the bearing plate 41 will tilt due to the speed difference between the two lead screws 52, making it difficult to lift the bearing part.

[0055] Reference Figure 2 and Figure 4Currently, the commonly used quick cleaning method is for workers to manually sweep with brooms. If the bearing part pushes the impurities upwards, and the bearing part is higher than the upper surface of the central movable comb plate 2 and the fixed comb plate 3, it will inevitably cause some inconvenience to the broom in sweeping the impurities. Therefore, the optimal situation is that the upper surface of the elastic bearing cover 46 is exactly flush with the upper surface of the central movable comb plate 2 and the fixed comb plate 3.

[0056] If workers directly observe with their naked eyes whether the upper surface of the elastic bearing cover 46 is flush with the upper surfaces of the central movable comb plate 2 and the fixed comb plate 3, it is somewhat inconvenient. Therefore, a display mechanism is also provided at the curb.

[0057] The display mechanism includes a solar generator 71 mounted on the curb by expansion bolts. The battery of the solar generator 71 is electrically connected to an electrical pin 72, which is bolted to the lower surface of the fixed comb plate 3 at the end of the corresponding support plate 41.

[0058] The display mechanism also includes a conductive post 73 threaded onto the support plate 41, and the conductive post 73 is electrically connected to a bulb 74. When the support plate 41 rises under the action of the lifting part, it drives the conductive post 73 to rise. When the conductive post 73 contacts the electrical pin 72, the solar generator 71 supplies power to the bulb 74, and the bulb 74 lights up.

[0059] When the bulb 74 just lights up, the operator stops operating the lifting unit. At this time, the upper surface of the elastic bearing cover 46 is exactly flush with the upper surfaces of the central movable comb plate 2 and the fixed comb plate 3.

[0060] After cleaning, the lifting unit drives the carrier plate 41 to descend and reset, the conductive post 73 disconnects from the electrical pin 72, and the bulb 74 goes out.

[0061] Reference Figure 1 and Figure 4 To reduce the possibility of passersby operating the cleaning device at will, a hollow protective box 8 is bolted to the curb. One lifting unit corresponds to one protective box 8, and the lifting unit is located inside the corresponding protective box 8. The light bulb 74 is installed inside the protective box 8.

[0062] The protective box 8 is locked with a lock, and only cleaning workers can operate the cleaning device to clean by opening the protective box 8 with a key.

[0063] The implementation principle of the impurity cleaning device for the expansion joint of the multi-directional displacement comb plate in this application embodiment is as follows: Under the action of the compression spring 45, the two bearing arms 44 cooperate to open the elastic bearing cover 46, so that the elastic bearing cover 46 is in close contact with the side wall of the central movable comb plate 2 and the fixed comb plate 3 corresponding to the cavity. After impurities enter the cavity, they can only accumulate on the elastic bearing cover 46.

[0064] When the protective box 8 is opened, two cleaning workers work together to rotate the two lead screws 52 in a forward direction. Under the action of the two lead screws 52, the bearing plate 41 is driven to move upward, so that the elastic bearing cover 46 can gradually push the impurities out of the cavity.

[0065] When the conductive post 73 on the support plate 41 contacts the electrical pin 72 on the fixed comb plate 3, the solar generator 71 supplies power to the bulb 74, the bulb 74 lights up, and the cleaning worker stops operating the lifting unit. At this time, the upper surface of the elastic support cover 46 is just flush with the upper surfaces of the fixed comb plate 3 and the central movable comb plate 2, and the cleaning personnel quickly sweep away the impurities with a broom.

[0066] Then, two workers work together to rotate the lead screw 52 in opposite directions, the lifting mechanism drives the bearing mechanism to reset, the bulb 74 goes out, and the cleaning workers reseal the protective box 8.

[0067] Using the methods described above, cleaning workers can quickly remove impurities, thus saving labor and time.

[0068] This application also discloses a cleaning method for a multi-directional displacement comb plate expansion joint impurity cleaning device, including the following steps:

[0069] S1. Set up roadblocks: Set up warning roadblocks on both sides of the expansion joint of the multi-directional displacement comb plate;

[0070] S2, Lifting and Cleaning: Open the protective box 8, and two workers work together to rotate the rotating wheel 53 in the forward direction. The rotating wheel 53 drives the lead screw 52 to rotate, and the bearing plate 41 moves upward under the action of the lead screw 52. The bearing plate 41 drives the bearing part and the conductive column 73 to rise, and the elastic bearing cover 46 gradually pushes the impurities out of the cavity. When the conductive column 73 contacts the electrical pin 72, the bulb 74 lights up. At this time, stop operating the lifting part. The upper surface of the elastic bearing cover 46 is just flush with the upper surface of the central movable comb plate 2 and the fixed comb plate 3. At this time, the cleaning personnel quickly sweep away the impurities with a broom.

[0071] S2. Reset and remove obstacles: Two workers work together to rotate the wheel 53 in opposite directions, thereby resetting the load-bearing mechanism and the lifting mechanism. The operator then re-closes the protective box 8 and removes the warning roadblock.

[0072] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
