Description

Technical Field

[0001] This utility model relates to a hydraulic milling and roughening machine, belonging to the field of concrete construction technology. Background Technology

[0002] Hydraulic milling and roughening machines are professional equipment widely used in road construction, tunnel engineering and other fields. They are mainly used for milling, roughening and renovation of concrete and asphalt pavements.

[0003] Utility model patent number 202420052613.9 discloses a pneumatic chiseling integrated machine, including a tracked chassis assembly with a chassis support platform. A rotating platform is mounted on the chassis support platform via a slewing support. An operating platform is mounted on the chassis support platform on one side of the slewing support. One end of a movable arm is mounted on the rotating platform. A pneumatic chiseling head is mounted at the end of the movable arm. A compressed air supply device for driving the pneumatic chiseling head is mounted on the upper surface of the chassis support platform. The compressed air supply device includes an air tank mounted on the upper surface of the front end of the chassis support platform. An air compressor is integrated on the air tank. The air outlet of the air tank is connected to the pneumatic chiseling head through an air passage.

[0004] While the aforementioned patents can be used for milling, roughening, and refinishing of concrete and asphalt pavements, current technology is not comprehensive and has the following drawbacks: 1. The lack of an adjustable rocker arm A and an angle limiting mechanism prevents the use of the combined action of the adjustable rocker arm A and the angle limiting mechanism to achieve self-adjustment of the milling head's left-right roughening balance. 2. The small excavator chassis lacks stability, and equipping it with a new hydraulic system is complex, cumbersome, and has a high failure rate. 3. It cannot meet the requirements for cooling and dust removal, resulting in a poor working environment.

[0005] To solve one of the above problems, a hydraulic milling and roughening machine is urgently needed. Utility Model Content

[0006] Based on the shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to adjust the left and right chiseling balance of the milling head by adding an adjustable rocker arm A and an angle limiting mechanism, so that it can be used not only for chiseling tunnels, but also for construction road milling, wall milling and other working environments. Therefore, a hydraulic milling and chiseling machine is provided.

[0007] The hydraulic milling and roughening machine of this utility model includes a tracked chassis assembly, a machine body, and an operating lever located at the front of the machine body. The tracked chassis assembly has track wheel assemblies on both sides. The machine body is rotatably mounted on the tracked chassis assembly. The machine body integrates a hydraulic control system and an engine, and also includes a working robotic arm. One end of the working robotic arm is mounted on the machine body. The feature is that a milling head is mounted on the other end of the working robotic arm. The milling head includes a protective shell assembly with an opening and an adjustable swing arm B hinged to the end of the working robotic arm. The two ends of the adjustable swing arm B are rotatably connected to the left or right protective plate of the protective shell assembly through a set of adjustable rocker arms A. An angle limiting mechanism is installed on the adjustable rocker arms A to limit the rotation angle of the protective shell assembly. A milling machine cutter hub assembly and a hydraulic motor for driving the milling machine cutter hub assembly to rotate are installed inside the protective shell assembly.

[0008] This equipment can be used not only for roughening tunnels, but also for milling road surfaces and walls. With the addition of an adjustable rocker arm A and an angle limiting mechanism, the milling head can automatically adjust the left and right roughening balance, which is an innovative design for uneven roads and walls.

[0009] This new patented, widened and enlarged tracked chassis ensures smooth movement and flexible steering. Compared to previous milling and roughening equipment, this all-diesel hydraulic milling and roughening machine offers superior operational performance, better human-machine integration, 360-degree rotation, and suitability for a wider range of working conditions. The optimized hydraulic system is energy-efficient and highly effective, significantly improving work efficiency. Equipped with a dust removal system, it saves manpower and greatly improves the working environment during tunnel roughening.

[0010] Preferably, the protective shell assembly is formed by welding together a front protective plate, a rear protective plate, a left protective plate, a right protective plate, and a top plate. A set of limiting wheels B is installed on the outer side of the left and right protective plates, and two sets of limiting wheels A are installed on the outer side of the front and rear protective plates.

[0011] Limit wheel A is used to adjust the roughening depth of vertical walls and ground; limit wheel B is used to adjust the roughening depth of curved walls in tunnels.

The cutter head is equipped with 6 evenly distributed spindles. Alloy blades are staggered and separated by spacers on the spindles. Under the high-speed rotation of the blades, the centrifugal alloy blade tips will cut the concrete surface, thereby improving the roughening effect.

[0015] The milling machine's cutter hub assembly uses a slant-shaft high-speed piston motor to provide the main power. It has a compact structure, strong power, and is suitable for harsh working conditions.

[0016] Power is transmitted by belt, which is convenient for maintenance. At the same time, the belt can provide soft protection for the equipment, so that it is less likely to damage other parts and ensure personal safety in case of overload.

[0018] Preferably, it also includes a driver capable of changing the tilting angle of the adjustable swing arm B, the driver causing the angle between the adjustable swing arm B and the working robot arm to change, the driver being a hydraulic cylinder.

[0019] Preferably, the fuselage is mounted on the tracked chassis assembly via a slewing mechanism, allowing the fuselage to rotate relative to the tracked chassis assembly about the central axis of the slewing mechanism.

[0020] Preferably, the engine is a diesel engine, and the engine body integrates a diesel tank for supplying fuel to the engine and a cooling system for cooling the engine, as well as a hydraulic oil tank that is matched with the hydraulic control system.
