Description

Technical Field

[0001] The present invention relates to the technical field of highway bridges, and particularly relates to a crack repair device for highway bridges and a repair method thereof. Background Art

[0002] With the acceleration of the urbanization process and the expansion of the transportation network, the maintenance needs of infrastructure such as roads and floors are increasing day by day. Traditional repair techniques rely on manual or semi-mechanized equipment to complete, and there are problems such as low efficiency, unstable construction quality, and environmental pollution. Especially in asphalt, concrete repair or the construction of new composite materials, how to achieve efficient mixing, precise discharging, environmentally friendly operation, and rapid on-site liquid supplement has become a technical bottleneck that the industry urgently needs to break through.

[0003] In the prior art, repair projects usually adopt a combination of split equipment: the mixing equipment is responsible for mixing the repair materials, the transport vehicle transfers the materials to the site, and then the paving is completed by manual or simple spraying devices. This process has significant defects:

[0004] The processes are disjointed and the efficiency is low. The stirring, transportation, and construction are carried out step by step, resulting in high time costs, and the materials are prone to segregation or solidification during transportation, affecting the final strength.

[0005] The discharging control accuracy is insufficient. The traditional liquid outlet depends on manual valves to adjust the flow rate, which is difficult to meet the differentiated requirements of complex road surfaces and is prone to material waste or incomplete local repair.

[0006] The environmental protection performance is weak. Pollutants such as volatile organic solvents and dust during the stirring process are directly discharged, endangering the health of construction workers and polluting the surrounding environment, and it is difficult to meet the increasingly strict environmental protection regulations.

[0007] The flexibility of liquid supplement is poor. Existing equipment lacks a rapid liquid supplement mechanism for local defects, and secondary repair requires re-preparing materials or reworking, further delaying the overall progress.

[0008] Therefore, a crack repair device for highway bridges and a repair method thereof are proposed to solve the above problems. Summary of the Invention

[0009] (1) Technical Problems to be Solved

[0010] Aiming at the deficiencies of the prior art, the present invention provides a crack repair device for highway bridges and a repair method thereof, which solve the technical problems raised in the background art.

[0011] (2) Technical Solutions

[0012] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0013] A crack repair device for highway bridges, including

[0014] The vehicle frame serves as the load-bearing body of the device and is formed by welding high-strength steel. Two groups of driving wheels are symmetrically installed at the bottom, and the driving wheels are driven by a motor through a gearbox to achieve the forward and backward movement and steering of the device. Telescopic side push rods are provided on both sides of the vehicle frame. The side push rods are controlled to expand and contract by hydraulic cylinders. One end of each side push rod is hinged to the vehicle frame, and the other end is respectively connected to the linkage components of the second pull rod and the liquid supplement module. An installation space is reserved in the middle of the vehicle frame for fixing the purification tower and the mixing tank.

[0015] Preferably, the configuration and working process of the mixing module

[0016] The mixing tank is a cylindrical stainless steel container. An openable and closable feed port is provided at the top. A mixing rod is vertically installed on the central axis inside the tank. Spiral blades and radial mixing paddles are welded on the surface of the mixing rod and are driven to rotate by a motor at the top of the tank body. The bottom of the mixing tank is a conical output chamber, which is directly connected to the transport pipe.

[0017] Preferably, the measuring rod is integrated into the inner wall of the mixing tank and includes an ultrasonic liquid level sensor and a viscosity sensor to monitor the liquid level height and the mixing uniformity of the material in real time. The data is fed back to the control terminal to automatically adjust the mixing speed or trigger liquid supplement.

[0018] Preferably, the linkage control of the liquid outlet module

[0019] The transport pipe extends from the output chamber of the mixing tank to the front end of the vehicle frame, and the end is connected to the main liquid outlet. An electromagnetic valve is installed inside the main liquid outlet as a switching valve and is opened and closed through the control terminal or a manual button. A machine pump is integrated at the bottom of the mixing tank to pressurize and transport the mixed repair liquid to the main liquid outlet. A flow regulating valve can also be optionally equipped at the main liquid outlet to meet the flow rate requirements of different construction scenarios.

[0020] Preferably, the mechanical linkage and screening function of the liquid supplement module

[0021] The liquid supplement module realizes linkage control through the expansion and contraction of the side push rods:

[0022] The secondary liquid outlet is opened at the lower part of the side wall of the mixing tank, and a rotary valve is installed outside it. The valve rotating shaft is fixed to one end of the liquid outlet pull rod.

[0023] Preferably, one end of the second pull rod is hinged to the side push rod, and the other end is hinged to the liquid outlet pull rod. When the side push rod extends outwards, the second pull rod pushes the liquid outlet pull rod to rotate, thereby opening the secondary liquid outlet.

[0024] Preferably, the guide plate is fixed obliquely on the outer wall of the mixing box, directly below the secondary liquid outlet, and adopts a corrugated plate design to mitigate fluid impact; the lower screen is fixed on the side of the frame through a bracket, and the screen aperture is -mm, which is used to filter agglomerated impurities in the repair fluid. The end of the guide plate is connected to the upper edge of the lower screen to ensure that the liquid flows evenly to the construction surface after being filtered by the screen.

[0025] Preferably, the exhaust gas treatment of the purification module

[0026] The purification tower is a vertical tower body, connected to the top of the mixing box through a pipeline. The tower is equipped with a multi-layer treatment structure: the lower layer is an activated carbon adsorption layer, the middle layer is an acid-base neutralization reaction chamber (filled with alkaline fillers), and the upper layer is an exhaust fan. The volatile gas generated during the mixing process is pumped into the purification tower through a pipeline, and is discharged from the top after being adsorbed and neutralized in turn.

[0027] Preferably, the mechanical drive linkage of the stirring rod

[0028] The rotational power of the stirring rod is achieved through the compound movement of the second pull rod: when the side push rod is extended and retracted, the second pull rod synchronously drives the stirring rod at the bottom of the stirring rod, converting the linear motion into the periodic forward and reverse rotation of the stirring rod, thereby enhancing the material mixing efficiency. This design can be used for linkage stirring during the liquid replenishment operation to avoid precipitation.

[0029] A method for repairing cracks in a highway bridge, the operation method is as follows:

[0030] The driving wheel moves the device to the area to be repaired, the control terminal starts the stirring motor, and the materials are mixed in the mixing box; the main liquid outlet is opened, and the repair liquid is pumped out to the construction surface through the transport pipe;

[0031] When a local area needs to be replenished, the push rod on the operating side is extended to open the secondary outlet in linkage, and the repair fluid is accurately replenished after being guided by the guide plate and filtered by the lower screen.

[0032] During the stirring and liquid discharge process, the purification tower processes the exhaust gas in real time, and the measuring rod monitors the data and automatically optimizes the parameters.

[0033] Preferably, the rotary switch of the secondary liquid outlet can be replaced by a solenoid valve, which is automatically opened and closed by a sensor signal;

[0034] The lower screen uses a vibration motor to assist screening to prevent clogging;

[0035] The measuring rod is integrated with a wireless transmission module to send data remotely to a mobile terminal.

[0036] (III) Beneficial effects

[0037] The present invention provides a novel intelligent road repair device. Through the collaborative design of a frame module, a stirring module, a dual liquid outlet system (main liquid outlet and liquid supplement module), and a purification module, the limitations of traditional equipment are broken through. Its core innovation lies in:

[0038] 1. Mechanical linkage drive. The side push rod and the pull rod mechanism couple the movements of moving, stirring, and liquid supplementing, simplifying the operation process and reducing energy consumption;

[0039] 2. Hierarchical discharging system. The main liquid outlet is responsible for large-scale paving, and the liquid supplement module realizes local fine repair through screening and diversion. The two complement each other to improve the construction quality;

[0040] 3. Closed-loop environmental protection design. The purification tower is directly connected to the stirring tank to achieve integrated control of waste gas generation, collection, and treatment, reducing pollution emissions from the source;

[0041] 4. This device is not only applicable to road repair, but can also be extended to fields such as floor construction and crack filling operations, providing an efficient and environmentally friendly solution for infrastructure construction and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
