Road construction trimming device with multistage tamping columns

Abstract

The invention discloses a road construction trimming device with multistage tamping columns. The road construction trimming device comprises a first supporting leg, a second supporting leg and a motor; a supporting frame is fixed to the lower end of the first supporting leg, a track rotating wheel is fixed to the lower end of the supporting frame, and the second supporting leg is provided with thesame structure with the first supporting leg; a rotary shaft is fixed to an output shaft on the left side of the motor, four arc-shaped rotating shafts are arranged on the left side of the rotary shaft and are sleeved with casing pipes, upper fixing rods are fixed to the lower ends of the casing pipes, and the lower ends of the upper fixing rods are inserted in lower casing pipes in a penetratingmode; and the lower ends of the lower casing pipes are rotatably connected with connecting joints through fixing shafts, the lower ends of the connecting joints are fixed to sliding rods, and tampingblock plates are fixed to the lower ends of the sliding rods. According to the road construction trimming device with the multistage tamping columns, the tamping effect is good, the road constructiontrimming device is suitable for the ground with large clods or hard soil, tamping on the ground with the different loosen degree is facilitated, the device size is small, and the road construction trimming device with the multistage tamping columns is advantageously applied to the narrow pavement and courtyards with short and narrow doors.

Description

technical field [0001] The invention relates to a road construction finishing device, in particular to a road construction finishing device with multi-stage tamping columns. Background technique [0002] Ram is a Chinese word with the original meaning of reinforcement, and the extended meaning is to lay a solid foundation, and it is mostly used in the construction industry. Use heavy objects to repeatedly fall freely to tamp the foundation or fill soil and stone to improve its compactness. Ramping, tamping, or tamping, originally used to tamp the foundation with hard objects such as stones by manpower when building a house. Usually, more than 2 people cooperate to complete the work. Now the work of compacting the foundation is changed to mechanical compaction, also known as electric compaction. [0003] Before laying asphalt or concrete, it is necessary to level and compact the dirt road. In the process of road construction, it often happens that the road foundation is not...

Problems solved by technology

[0003] Before laying asphalt or concrete, it is necessary to level and compact the dirt road. In the process of road construction, it often happens that the road foundation is not comprehensive, the foundation is not flat and firm enough, and the quality of the road foundation is not guaranteed. Asphalt or concrete pavement is undulating, and it is easy to form cracks or pits under rain and heavy pressure

[0004] At present, large tamping machines are not suitable for tamping narrow courtyards with narrow roads and gates. The small tamping machines on the market are not suitable for tamping the ground with large clods or hard soil. Controlled compaction of ground with varying degrees of porosity
