Description

Technical Field

[0001] This utility model relates to the field of road maintenance equipment technology, specifically to a rapid de-icing device for bridges and roads. Background Technology

[0002] In winter snowfall, bridge surfaces are more prone to forming stubborn ice layers compared to ordinary roads. This is due to the unique structure of bridges: First, the suspended nature of bridges exposes both their upper and lower surfaces to cold air, creating a two-way heat dissipation effect; second, the lack of ground-based heat radiation compensation around bridges causes heat loss to occur 2-3 times faster than on ordinary roads; third, forced convection heat transfer occurs on the bridge surface under wind force, further accelerating the cooling process. These special conditions often result in a dense ice layer of 1-3 cm thickness forming on bridge surfaces within 1-2 hours after snowfall.

[0003] Currently, bridge de-icing operations mainly rely on manual labor using simple tools such as shovels. This method has many drawbacks: workers need to bend over for long periods of time, which is labor-intensive and poses safety hazards; the area covered by a single operation is limited, and the de-icing efficiency is usually less than 10 square meters per hour; more importantly, some lanes need to be closed during de-icing operations, and prolonged ice breaking seriously affects traffic efficiency. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a rapid de-icing device for bridges and roads.

[0005] This utility model is achieved through the following technical solution:

[0006] This application provides a rapid de-icing device for bridges and roads, including a support shaft and two supporting movable wheels on both sides. Handrails are fixed on both sides of the support shaft, and force transmission rods are connected to the ends of the handrails. A support crossbar is connected between two force transmission rods. Multiple electric impact hammers are connected to the support crossbars through multiple sliding components. An ice-breaking shovel for breaking the ice layer on the road is fixed to the impact rod of the electric impact hammer.

[0007] Furthermore, this application also proposes that one end of the handrail is positioned obliquely upward towards the support shaft, and the other end of the handrail is bent inward along the support shaft and connected to the force transmission rod. The handrail, through the support shaft, uses the force transmission rod as a support point to apply downward ice-breaking pressure to the electric impact hammer.

[0008] Furthermore, this application also proposes that the sliding assembly includes a sliding sleeve that is slidably fitted onto the support crossbar, the upper and lower ends of the sliding sleeve being clamped and fixed to the electric impact hammer by a connecting clamp, and a fixed locking screw being provided on the sliding sleeve.

[0009] Furthermore, this application also proposes that a counterweight be installed in the middle of the support shaft to prevent it from wobbling.

[0010] Furthermore, this application also proposes that the ice-breaking shovel is arranged parallel to the support shaft and perpendicular to the road ice layer.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model, through the linkage structure of the support shaft, the handrail, the force transmission rod and the support crossbar, combined with the coordinated operation of multiple electric impact hammers and ice-breaking shovels, can quickly and effectively break the road ice layer, solving the problems of low efficiency and high labor intensity of traditional manual ice removal. It has the advantages of improving ice removal efficiency, reducing labor intensity and ensuring operational safety. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0017] like Figure 1-3 As shown, this application proposes a rapid de-icing device for bridges and roads, including a support shaft and two supporting movable wheels on both sides. Handrails are fixed on both sides of the support shaft, and force transmission rods are connected to the ends of the handrails. A support crossbar is connected between the two force transmission rods. Multiple electric impact hammers are connected to the support crossbars through multiple sliding components. An ice-breaking shovel for breaking the ice layer on the road is fixed to the impact rod of the electric impact hammer.

[0018] The support shaft can be made of solid steel column, with a diameter ranging from 30-50mm and a length of 0.8-1m. Rubber tires with a diameter of 200-300mm are preferred for the support wheels. The handrail tilt angle is 30-45 degrees. The force transmission rod and handrail are integrally bent, with a circular or rectangular cross-section. The support crossbar is preferably made of aluminum alloy, with a length matching the support shaft. The sliding component can adopt a sliding sleeve structure. The electric impact hammer's impact frequency is adjustable from 10-30 times / minute, with a single impact energy of 10-20J. The ice-breaking shovel is made of high-strength alloy steel, with a blade angle of 30-45 degrees and a width of 100-150mm. The electric impact hammer uses the Dayi A7 model, equipped with a 20V / 4000mA lithium battery, which can be used for 1-1.5 hours on a full charge, sufficient for impact ice breaking.

[0019] This device converts manual labor into the impact force required for ice-breaking operations through a mechanical structure. The lever system, consisting of a handle and a force transmission rod, amplifies the force applied by the operator. The cooperation between the support crossbar and the sliding assembly enables the lateral adjustability of the ice-breaking shovel, accommodating ice removal needs of varying widths. The combination of the impact of the electric impact hammer and the cutting action of the ice-breaking shovel increases work efficiency by 3-5 times compared to traditional manual shovel ice removal. The movable wheels allow the device to be moved along the bridge deck, avoiding the physical exhaustion caused by frequent manual relocation. The overall structural design takes into account the special requirements of the bridge environment, enabling stable operation in cold conditions.

[0020] Furthermore, this application also proposes that one end of the handrail is positioned obliquely upward towards the support shaft, and the other end of the handrail is bent inward along the support shaft and connected to the force transmission rod. The handrail, through the support shaft, uses the force transmission rod as a support point to apply downward ice-breaking pressure to the electric impact hammer.

[0021] Specifically, the handle adopts a structural design combining inclination and bending. The upward-sloping end increases the lever arm length during operation, while the inward-bending end ensures the straightness of the force transmission path between the force transmission rod and the electric impact hammer. As a preferred embodiment, the angle between the handle and the support shaft can be set to 30-60 degrees, and the bending angle of the force transmission rod connection is preferably 120-150 degrees. The position of the support point is determined by calculating the leverage ratio, allowing the force applied by the operator to be amplified 2-3 times and transmitted to the ice-breaking shovel. The locking screw can be quickly adjusted using a wing nut, and the connecting clamp uses a detachable sleeve clamp with a rubber pad, which not only facilitates disassembly but also protects the electric impact hammer.

[0022] Therefore, this technical solution optimizes the geometry of the handrail to convert the lateral thrust of manual operation into vertical pressure on the ice-breaking shovel. Compared to the traditional method of direct downward pressure, this design allows the operator to apply ice-breaking pressure more effortlessly using the lever principle, while maintaining effective force transmission. Experiments show that under the same human input conditions, this structure can improve ice-breaking efficiency by more than 40%, and significantly reduce operator fatigue. This improvement is particularly suitable for bridge de-icing scenarios requiring long-term continuous operation, solving the technical challenges of high labor intensity and difficulty in controlling the direction of force during manual ice breaking.

[0023] Furthermore, this application also proposes that the sliding assembly includes a sliding sleeve that is slidably fitted onto the support crossbar, the upper and lower ends of the sliding sleeve being clamped and fixed to the electric impact hammer by a connecting clamp, and a fixed locking screw being provided on the sliding sleeve.

[0024] The sliding sleeve is made of high-strength, wear-resistant material, and its inner wall has a friction-reducing coating to decrease sliding resistance. The connecting clamp can adopt a quick-release clamp structure for easy maintenance and replacement of the electric impact hammer. The locking screw has an anti-loosening design, and the sliding sleeve is positioned and fixed by tightening the thread. As a preferred embodiment, the sliding sleeve and the support crossbar are square to prevent the sliding sleeve from rotating.

[0025] This technical solution achieves flexible movement and accurate positioning of the electric impact hammer on the support crossbar through the sleeve-fitting mechanism of the sliding sleeve. The connecting clamp ensures a stable connection between the electric impact hammer and the sliding sleeve, while the locking screw reliably fixes the position of the sliding sleeve. Therefore, the distribution spacing of multiple electric impact hammers can be adjusted according to actual de-icing needs, improving the adaptability and efficiency of de-icing operations. Compared with fixed installation methods, this design significantly improves the ease of adjustment and flexibility of use of the device, better adapting to the handling needs of different icing conditions.

[0026] Furthermore, this application also proposes that a counterweight be installed in the middle of the support shaft to prevent it from wobbling.

[0027] The counterweight can be made of cast iron, concrete, or steel, and its weight is calculated based on the length of the support shaft and the working intensity of the electric impact hammer. In practice, the counterweight is fixed to the middle of the support shaft by bolts or welding. Welding is suitable for long-term use, while bolting facilitates later maintenance and adjustment. As a preferred implementation, the counterweight is designed as a detachable structure, allowing for adjustments to the number of counterweight modules to adapt to different working conditions. For example, in strong winds, the number of counterweights can be increased to 120% of the standard value, while in stable conditions, it can be reduced to 80%.

[0028] This technical solution effectively suppresses the longitudinal sway of the support shaft during ice-breaking operations by using a counterweight. Its working principle is as follows: when the electric impact hammer applies a vertical impact force to the ice layer, the inertial torque generated by the counterweight counteracts the sway caused by the support shaft. Specifically, when the center of mass of the counterweight coincides with the center of rotation of the support shaft, the instability caused by the lever effect is minimized. Compared with devices without a counterweight, this design allows the ice-breaking shovel to maintain perpendicular contact with the ice layer, avoiding the problem of decreased ice-breaking efficiency due to equipment sway. Experimental data shows that, under the same operating conditions, the device with a properly configured counterweight increases ice-breaking efficiency by approximately 15% and extends equipment life by more than 20%.

[0029] Furthermore, this application also proposes that the ice-breaking shovel is arranged parallel to the support shaft and perpendicular to the road ice layer.

[0030] Specifically, the installation angle of the icebreaker is achieved as follows: the cutting edge of the icebreaker is parallel to the axis of the support shaft, while the cutting edge forms a 90-degree perpendicular angle with the surface of the ice layer on the road. As a preferred embodiment, the icebreaker can be made of high-hardness alloy steel, with a serrated cutting edge to enhance the ice-breaking effect.

[0031] Therefore, this technical solution optimizes the spatial orientation of the ice-breaking shovel, ensuring that the impact force generated by the electric impact hammer acts perpendicularly to the ice surface, thus significantly improving the ice-breaking efficiency of a single impact. Compared to the existing method of manually shoveling ice at an angle, this vertical impact method makes fuller use of impact energy, avoids the dispersion and loss of impact force, and can reduce the number of impacts by approximately 40% under the same working conditions. In practice, operators only need to push the device along the bridge surface without additional adjustments to the ice-breaking angle, reducing labor intensity and improving work efficiency.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
