Description

Concrete road surface grooving machine

Technical Field

The utility model belongs to a concrete road surface grooving machine.

Background

At present, in order to increase the friction force of a concrete pavement and prevent a running automobile from slipping, grooving treatment needs to be carried out on the surface of the concrete pavement, namely, grooves with the depth of about 5-7 mm are densely distributed at intervals in the transverse direction of the concrete pavement. The grooving treatment process is that after concrete curing, a mechanical grooving machine is utilized to perform grooving operation on a solidified concrete pavement, the mechanical grooving machine mechanically drives a cutting piece to rotate to polish the concrete pavement to form grooves, and when the mechanical grooving machine works, dust is raised, noise is huge, environmental pollution is large, construction progress is slow, construction period is prolonged, efficiency is low, and time and labor are wasted. This process still needs purchase many mechanical grooving machines, 2 ~ 3 people cooperation and spills water dust fall construction, need continuous refueling or provide electric power (the construction of remote mountain area is difficult to provide), add water, purchase and trade the cutting piece in the construction, and water consumption is huge, is the problem that is difficult to solve to the water shortage area, and the grooving in-process also can cause the pollution to the road surface simultaneously.

Disclosure of Invention

The utility model aims at designing a machines of concrete road surface grooving, can receive the concrete before solidifying to carry out the grooving to the concrete road surface, have simple structure, the grooving degree of depth is adjustable, and is swift convenient, stops environmental pollution, and the construction progress is fast, the energy can be saved, labour saving and time saving's advantage.

Therefore, the utility model discloses constitute by the handle pole, the rear end that is a plurality of rake teeth that the spacing distance set up side by side is fixed as an organic whole with the preceding terminal surface of rake body, and the front portion of a plurality of rake teeth extends to the front portion of rake body, and the front end of each rake tooth is on same straight line. The front end of the handle rod is fixed in the middle of the rear end face of the rake body, and the weight box is arranged at the front end of the handle rod and in the middle of the rear end face of the rake body corresponding to the front end of the handle rod. The inlet of the weight box is arranged towards the rear end of the handle rod, and a balancing weight is placed in the weight box.

The rake teeth are made of reinforcing steel bars with the length of 20cm and the diameter of 2-5 mm. The weight box is a rectangular or cylindrical barrel body with an inlet at the upper end. The balancing weight is an iron block or a stone block. The rake teeth are arc-shaped.

Above-mentioned structural design has reached the utility model discloses a purpose.

The utility model discloses can carry out the grooving to the concrete road surface before the concrete is received the face and is not solidified, have simple structure, the grooving degree of depth is adjustable, and is swift convenient, stops environmental pollution, and the construction progress is fast, the energy can be saved, labour saving and time saving's advantage.

Before the concrete collection surface is not solidified, the handle rod is held by a hand, the rake teeth are arranged on the surface of the concrete, the handle rod is pulled forwards and pressed downwards, and the plurality of rake teeth are pressed into the surface of the concrete to realize concrete surface grooving, so that the concrete surface grooving device has the characteristic of quickly, conveniently and better realizing concrete surface grooving, the concrete surface grooving efficiency is greatly improved, and the construction progress is accelerated; the consumption of material equipment such as water, oil, electricity, grooving sheets, grooving machines and the like is avoided, the construction cost is greatly saved, and the construction benefit is improved. Can realize the grooving construction of the concrete pavement quickly, conveniently and better. The utility model discloses be equipped with the weight box on the front end of handle bar and the rake body rear end face middle part that corresponds, it establishes the balancing weight that varies weight, can increase and decrease the displacement of balancing weight in the weight box as required, and the gravity of a plurality of rake teeth of increase and decrease in the concrete surface can obtain the effect of different degree of depth surface grooving as required, and also need not push down the handle bar for this reason, guarantees that the grooving degree of depth is accurate and laborsaving.

Detailed Description

As shown in figure 1, the machine for grooving concrete pavement comprises a handle bar 1, the rear ends of a plurality of rake teeth 4 which are arranged side by side at intervals are fixed with the front end surface of a rake body 3 into a whole, and the rake body is transversely arranged. The front parts of the plurality of rake teeth extend towards the front part of the rake body, and the rake teeth are arc-shaped. The rake teeth are made of reinforcing steel bars with the length of 20cm and the diameter of 2-5 mm. The front ends of the rake teeth are on the same straight line. The rake body can be made of a rectangular steel pipe body of 7cm multiplied by 4cm, the front ends of rake teeth are welded and fixed on the axis of the middle of the front end face of the rake body side by side at intervals, the handle rod is a steel pipe of 2.5cm, and the front end of the handle rod is fixed in the middle of the rear end face of the rake body through welding.

The front end of the handle rod and the middle part of the rear end surface of the corresponding rake body are fixedly provided with a weight box 2 through welding. The weight box is made of sheet iron. The inlet of the weight box is arranged towards the rear end of the handle rod, and a balancing weight is placed in the weight box. The weight box is a rectangular or cylindrical barrel body with an inlet at the upper end. The balancing weight is an iron block or a stone block.

When the concrete collection face grooving machine is used, a plurality of balancing weights with adaptive weights can be placed in the weight box according to the depth of concrete road face grooving, before a concrete collection face is not solidified, the handle rod is held by a hand, rake teeth are placed on the surface of concrete, the handle rod is pulled forwards, and the plurality of rake teeth are pressed into the surface of the concrete to realize concrete face grooving.

In a word, the utility model discloses can not solidify the preceding concrete road surface at the concrete receipts face and carry out the grooving, have simple structure, the grooving degree of depth is adjustable, and is swift convenient, stops environmental pollution, and the construction progress is fast, the energy can be saved, labour saving and time saving's advantage.
