Description

Technical Field

[0001] The utility model relates to the technical field of bridge deck cutting and repair at both sides of a bridge expansion joint, in particular to a bridge repair device. Background Art

[0002] When cleaning and maintaining a bridge, the main focus is to remove dirt, weeds and other debris from the surface of the bridge, remove rust and anti-corrosion treatments on metal structures, and waterproof and seal concrete structures; when repairing and reinforcing a bridge, it generally includes repairing cracks, holes and structural damage, replacing or repairing damaged expansion joints and other components, and reinforcing the structure to improve its bearing capacity and durability.

[0003] Expansion joints are set between beam ends, between beam ends and abutments, or at the hinged positions of bridges to ensure the smoothness and comfort of vehicle driving. Therefore, regular maintenance and repair of expansion joints are important to ensure the normal driving of vehicles.

[0004] For example, in the patent document with patent publication number CN210420853U, a bridge expansion joint maintenance component is disclosed, whose main structure includes a first support part, a second support part, and a connecting part. One end of the connecting part is connected to the second support part, and the other end of the connecting part is connected to the crossbeam in the bridge expansion joint displacement control box. The first support part is located in the middle of the connecting part, and a driving device is detachably arranged between the first support part and the second support part. When the first support part is fixed, the driving device drives the second support part to drive the connecting part to move, thereby driving the crossbeam in the bridge expansion joint displacement control box to move.

[0005] It can be seen from the above structure and its working principle that the existing bridge expansion joint repair assembly mainly realizes the lifting of the crossbeam through the cooperation of the first support part, the second support part, the connecting part and the driving device during the maintenance work.

Two spaced dust suction components are arranged at the rear side of the cleaning mechanism, and the two dust suction components are respectively used to realize negative pressure adsorption of dust at the rear side of the cleaning mechanism. Each lifting mechanism is in a synchronous lifting state when working. The bridge maintenance device in the utility model is used as a whole to complete cutting and cleaning of the bridge deck 7 at the expansion joint 6, so as to facilitate the subsequent maintenance of the expansion joint 6 and replacement of components such as anchors.

During the movement, the direction is controlled by manually holding the push handle 29. At the same time, according to the current width of the expansion joint 6, the corresponding seam edge bridge deck adjustment quick cutting mechanism is adjusted to be appropriately raised and lowered and extended in the horizontal direction, thereby driving the corresponding cutting unit to cut downward at high speed. When cutting, a spacing distance of 5cm-10cm needs to be reserved between the anchor. During the cutting process, the travel speed of the entire device is controlled, and the cleaning mechanism is used to clean the rear side after the cutting is completed to collect and absorb smaller impurities and particulate matter to reduce dust.

[0032] In any of the above schemes, it is preferred that the lifting mechanism includes a vertically arranged main lifting cylinder 2, the top of the main lifting cylinder 2 is fixed to the bottom of the lifting seat 1, and the bottom of the piston rod of the main lifting cylinder 2 is fixed to the top of the corresponding walking unit.

[0033] The lifting mechanism provided here is mainly used as a lifting and lowering control structure of the entire device to control the height position of the entire lifting seat 1 to facilitate obstacle crossing.

[0034] In any of the above schemes, it is preferred that the traveling unit includes a horizontally arranged lifting beam 3, the top of the lifting beam 3 is respectively fixed to the bottom of the piston rod of the main lifting cylinder 2 at the corresponding position, and wheel frames 4 are respectively installed at the bottom of both sides of the lifting seat 1, and a traveling wheel 5 is installed in the installation cavity of the wheel frame 4.

[0035] In any of the above schemes, it is preferred that the power component includes a dual-output shaft motor 9 fixed to the bottom of the middle section of the lifting beam 3 on the rear side through a connecting column 8, and a positioning seat 10 is respectively provided on one side of each output shaft of the dual-output shaft motor 9, and a connecting long shaft 11 is movably inserted in the rotating hole of each positioning seat 10, the inner end of the connecting long shaft 11 is coaxially fixed to the end of the output shaft of the dual-output shaft motor 9, and the outer end of the connecting long shaft 11 is coaxially fixed to the end of the wheel axle of the traveling wheel 5.

[0036] The walking unit drives the entire device by the rotation of the walking wheels 5.

It can rely on the extension and retraction of the corresponding first lifting cylinder 13 to drive the lifting and positioning of the first horizontal frame 14 at its bottom. At the same time, the extension of the piston rods of the first translation cylinders 15 inside the first horizontal frame 14 can drive the horizontal displacement of the cutting unit at its end. The displacements of the cutting units on both sides are independent of each other. Therefore, when center deviation occurs during walking, it can also be corrected by relying on the extension and retraction adjustment of the corresponding first translation cylinder 15, so as to facilitate alignment with the corresponding position during cutting.

[0040] When the cutting unit is working, it mainly relies on the cutting motor 19 to provide cutting power. When the cutting motor 19 is working, it drives the corresponding disc cutting tool 17 to rotate in the center. During the operation, the blade of the disc cutting tool 17 completes the cutting and slitting of the concrete of the bridge deck 7.

[0041] When controlling cutting, the cutting depth can be controlled by controlling the lifting and lowering of the piston rod of the first lifting cylinder 13 .

A second translation cylinder 23 which is symmetrically arranged opposite to each other is fixedly mounted in the mounting cavity of the second transverse frame 22. The second translation cylinder 23 is an electric cylinder structure with double piston rods extending in the same direction. A cleaning unit is fixedly mounted on the outer end of the piston rod of each of the second translation cylinders 23, and the cleaning unit follows the corresponding second translation cylinder 23 to complete the horizontal displacement.

[0043] The cleaning mechanism is mainly used to clean the area around the cutting seam after cutting. During the cleaning process, the height of the cleaning unit can be controlled by controlling the lifting of the second lifting cylinder 21 to achieve the purpose of quickly matching the current position to complete the cleaning.

[0044] In any of the above schemes, it is preferred that the cleaning unit includes a cleaning wheel frame 25 which is vertically arranged and fixed at the ends of the two piston rods of the second translation cylinder 23, and a disc cleaning brush 26 is installed in the U-shaped cavity of the cleaning wheel frame 25.

[0045] When the cleaning unit is working, the corresponding disc cleaning brush 26 is driven by the rotation of the cleaning motor 28, and at the same time, the bottom of the disc cleaning brush 26 can clean the surrounding area of ​​the cut of the bridge deck 7 to achieve the purpose of rapid cleaning.

[0046] In any of the above solutions, preferably, a push handle 29 is fixedly installed on the front top of the lifting seat 1; a storage compartment 30 is arranged on the top of the lifting seat 1, and the top of the storage compartment 30 is open.

[0047] By holding the push handle 29, it is convenient to exert force to control the displacement direction of the entire device.

[0048] The storage compartment 30 can be used to temporarily store tools or construction waste generated by cutting.

[0049] Embodiment 2: Compared with Embodiment 1, this embodiment further comprises the following technical features:

[0050] In any of the above schemes, it is preferred that the dust suction component includes a negative pressure pump 31 fixedly mounted on the top of the rear side of the lifting seat 1, and a connecting elbow 32 is installed at the air inlet of the negative pressure pump 31, and the vertical section of the connecting elbow 32 is movably and sealedly inserted in the upper tube cavity of a vertically arranged air guide riser 33, and the lower end of the air guide riser 33 passes downward to the top of the corresponding lifting beam 3 and movably and sealedly extends into the tube cavity of the vertical section of a dust suction elbow 24, and the end of the dust suction elbow 24 is bent toward the rear side of the disc cleaning brush 26 at the corresponding position and receives dust and particles generated during the cleaning process, and the vertical section of the dust suction elbow 24 is movably screwed into the threaded through hole at the corresponding lifting beam 3 through an external thread, and there is a relative displacement in the vertical direction between the tube cavity of the air guide riser 33 and the vertical section of the dust suction elbow 24.

[0051] It should be noted that, when the dust suction component is working, it mainly relies on the negative pressure pump 31, the connecting bend 32, the air guide riser 33 and the dust suction bend 24 to achieve the adsorption of particulate impurities. Before adsorption, the corresponding dust suction bend 24 is rotated by thread so that the dust suction port of the curved section at its lower end can be directed toward the cleaning part. At the same time, the lower end of the dust suction bend 24 adopts a flexible and bendable structure, and the inclination angle can be controlled and adjusted by bending and adjusting.

[0052] In addition, considering the lifting state of the entire lifting seat 1, when the lifting seat 1 is lifted, the lower end of the gas guide riser 33 is movable and sealed in the corresponding tube cavity, and when following the lifting seat 1 to be lifted, it can complete a relative vertical displacement in the corresponding tube cavity.

[0053] Specific working principle: The bridge maintenance device is used as a whole to complete the cutting and cleaning of the bridge deck 7 at the expansion joint 6, so as to facilitate the subsequent maintenance of the expansion joint 6 and the replacement of components such as anchors.

[0054] When working, first connect the entire device to the external outdoor power supply, adjust the entire device to the center line position of the expansion joint 6 of the bridge deck 7, control the power component to start, drive the walking unit to operate, and thus drive the entire device to move along the length direction of the expansion joint 6. During the movement, the direction is controlled by manually holding the push handle 29.

[0055] Before construction, it is necessary to adjust the corresponding seam edge bridge deck adjustment quick cutting mechanism according to the current width of the expansion joint 6, and adjust it in the horizontal direction, so as to drive the corresponding cutting unit to cut downward at high speed. When cutting, a spacing distance of 5cm-10cm needs to be reserved between the anchor.

[0056] During the cutting process, the travel speed of the entire device is controlled, and the rear side is cleaned by a cleaning mechanism after the cutting is completed to collect and absorb smaller impurities and particles to reduce dust.

[0057] From the above, it can be seen that the bridge maintenance device is mainly used for cutting and cleaning the bridge deck 7 on both sides of the anchors during the maintenance of the expansion joint 6 of the bridge deck 7, effectively ensuring the on-demand cutting and cutting of the bridge deck 7 concrete at the part to be repaired during the maintenance of the bridge deck 7, and relying on the cleaning mechanism to improve the cutting environment and reduce dust. When working, the entire device is controlled to be located at the center line of the expansion joint 6 and move along the length direction of the expansion joint 6. The entire device can move forward or stop as needed in cooperation with artificial propulsion and the operation of the power components and the walking unit, so that the feeding speed during the cutting or cleaning process can be controlled.

[0058] The device as a whole can be controlled to rise and fall on demand after being connected to an external power source, thereby ensuring effective obstacle-crossing capability when cutting the bridge deck 7 on both sides of the expansion joint 6, and effectively controlling the lifting height of the storage compartment 30, so as to facilitate the centralized storage and transfer of the remaining maintenance tools or construction waste generated during the maintenance process. Among them, when each cutting unit is cutting, it can control the spacing between the two relatively arranged cutting units according to the current spacing width on both sides of the expansion joint 6. After the adjustment is completed, the lifting and cutting depth is controlled under the action of the seam edge bridge deck adjustment quick cutting mechanism; when the cutting is completed, the cleaning unit can match the corresponding cutting unit by controlling the cleaning mechanism and clean the waste generated by its cutting part.

[0059] In addition, in order to avoid dust during cleaning, each dust suction component is used to complete negative pressure dust suction, which effectively ensures the good surrounding working environment; the direction of the dust suction port of each dust suction component can be adjusted by rotating the dust suction elbow 24 to improve the dust suction effect.
