Description

Technical Field

[0001] The utility model relates to the technical field of municipal road construction tools, in particular to a municipal road construction handcart. Background Art

[0002] Municipal road construction trolleys are manual transport vehicles specially designed for handling and transporting materials, tools or equipment at municipal road construction sites. They are commonly used in urban road maintenance, repair and construction projects, such as road paving, pavement repair, drainage system installation, etc.

[0003] However, at construction sites, especially when operating a trolley on a slope or uneven road surface, it is very easy to slip or lose control, resulting in personal injury or material loss. In addition, conventional trolleys are prone to sliding when parked, especially on slopes, which not only increases the labor intensity of workers, but also may cause safety accidents. Utility Model Content

[0004] In response to the above problems, the utility model provides a municipal road construction cart, which effectively solves the problem that the cart is very likely to slide or lose control when parked on a slope or carrying heavy loads, causing personal injury or material loss, and the cart is easy to slide when parked.

[0005] The utility model adopts the following technical solutions:

[0006] A municipal road construction hand cart comprises a base plate, three universal wheels and a brake wheel are installed at the bottom of the base plate, and the brake wheel comprises a wheel mounting plate, the wheel mounting plate is installed at the bottom of the base plate, a bracket is rotatably connected to the bottom of the wheel mounting plate, the wheel is installed on the bracket, an arc-shaped brake pad is arranged above the wheel, one side of the arc-shaped brake pad is connected to two rotating shaft sleeves, a rotating shaft is connected to the bracket above the wheel, the rotating shaft is located in the two rotating shaft sleeves and is rotatably connected thereto, one side of the arc-shaped brake pad is connected to a connecting key, the bottom of the wheel mounting plate is connected to an L-shaped plate above the connecting key, a spring is arranged between the L-shaped plate and the connecting key, a push rod is arranged on one side of the base plate, a handle mounting block is connected to the push rod, a brake handle is rotatably installed on the handle mounting block, the brake handle and the connecting key are connected by a brake line, and a spoon-shaped plate for fixing one end of the brake handle is rotatably arranged on the push rod at one side of the brake handle.

[0007] Furthermore, the brake line includes a metal wire, the outer surface of the metal wire is wrapped with a rubber tube, a hammer block is provided at one end of the metal wire, the hammer block is embedded in the brake handle, and the other end of the metal wire is fixedly connected to the connecting key by a spiral.

[0008] Furthermore, the shape of the brake handle is ergonomically designed, and the surface of the brake handle is provided with anti-slip patterns.

[0009] Furthermore, the wheel is made of rubber.

[0010] The advantages of the utility model are that the brake line is operated by the brake handle, and then pressure is applied to the wheel through the connecting key, L-shaped plate and spring-linked arc brake pad, generating effective friction to slow down or stop the vehicle. This brake mechanism responds quickly and can quickly stabilize the vehicle in an emergency. The ergonomic design of the brake handle and the non-slip texture on the surface provide additional comfort and grip stability, ensuring reliable operation even in wet or slippery conditions. The position of the brake handle can be fixed by the spoon-shaped plate, which can prevent the trolley from sliding or moving when no one is operating, ensuring the safety of the work area. The wheels are made of rubber material, which not only enhances the durability of the wheels and the ability to adapt to various road surfaces, but also helps to reduce noise during driving and improve comfort.
