Description
Technical Field
The utility model belongs to the coal mining field, concretely relates to a mould for building opencut highway safety barricade.
Background
According to the regulation of coal mine safety regulations, a safety retaining wall is required to be arranged for open pit road transportation, the height of the safety retaining wall is 2/5-3/5 of a mining truck, according to the regulation of open pit safety quality standardization, a slope surface is flat, and the concave-convex error within 30m of the length is not more than 2 m. Whether the safety retaining wall is arranged according to the paying-off requirement can directly influence the transportation safety, the soil discharge safety, the collecting and loading range, the slope flatness, the collecting and stripping quality and the like, and the setting requirement standard of the fixed slope to the boundary and the fixed transportation road on the safety retaining wall is extremely high.
At present, a small hydraulic back shovel is generally adopted in a strip mine to arrange a safety retaining wall, bulk materials need to be discarded, and the safety retaining wall is trimmed into a trapezoidal safety retaining wall, so that the working efficiency is low, the energy consumption is high, and the technical requirement of the quality of the safety retaining wall on a digging machine driver is high. It takes 4-6 hours to make a safety retaining wall of 100m using an excavator.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a mould for building strip mine highway safety barricade to solve the problem that current construction mode is inefficiency.
The technical scheme of the utility model is that: the utility model provides a mould for building strip mine highway safety barricade, includes roof and two blocks of curb plates, and two blocks of curb plates are connected respectively and are formed the trapezium structure below the roof both sides, are equipped with 2 at least connecting holes on the roof.
As a further improvement, the distance between the front ends of the two side plates is larger than the distance between the rear ends, and the distance between the front ends of the two side plates is larger than the distance between the rear ends. The front end is provided with a larger inlet, so that more materials can be conveniently brought in, and the resistance is reduced; the outlet at the rear end is smaller, which is beneficial to forming a compact wall body.
As a further improvement of the utility model, an internal thread is arranged in the connecting hole.
As a further improvement, the top plate and the side plates are made of steel plates, the materials are easy to take and are connected in a welding mode, and the steel plates are easy to process.
The utility model has the advantages that: the utility model discloses simple structure, the processing cost is low, hangs it through the connecting hole and installs on the chassis of installation before wheeled, and the installation rides in the windrow top before wheeled, can form safe barricade fast, and work efficiency is high, of high quality, and the time reduction that the safe barricade of preparation 100m needs is 2 hours, and the energy consumption is low.

fig. 4 is a cross-sectional view of the retaining wall.
In the figure: 1-a top plate; 2-side plate; 3-connecting holes; 4-soil material; 5-a safety retaining wall; l1-front end down spacing; l2-rear end lower spacing; k1-spacing on the front end; k2-spacing on the back end.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the mold for constructing the open pit mine road retaining wall comprises a top plate 1 and two side plates 2, wherein the two side plates 2 are respectively connected below two sides of the top plate 1 to form a trapezoidal structure, and at least 2 connecting holes 3 are formed in the top plate 1.
The lower distance L1 between the front ends of the two side plates 2 is greater than the lower distance L2 between the rear ends, and the upper distance K1 between the front ends of the two side plates 2 is greater than the upper distance K2 between the rear ends.
The connecting hole 3 is internally provided with internal threads.
The top plate 1 and the side plate 2 are both made of steel plates and are connected in a welding mode.
As seen in fig. 2, the front end lower spacing L1 and the front end upper spacing K1 are in the direction in which the wheel front loader advances.
Will the utility model discloses a connecting hole 3 hangs and installs on the chassis of wheeled front mounted machine, can carry out the operation.
The construction steps are as follows:
(1) paying off the position of the safety retaining wall, and discharging the soil 4 along the paying-off position (shown in figure 3);
(2) the utility model is suspended and installed on the chassis of the wheel type front loading machine, and the wheel type front loading machine rides above the stockpile to form a safety retaining wall 5 (as shown in figure 4);
(3) and cleaning residual bulk materials on the road side by using a wheel type front loader.
Utilize the utility model discloses construct the safety barricade, the time reduction that the safety barricade of preparation 100m needs is 2 hours.
The specific gravity of the diesel oil is 0.85kg/L calculated according to the fuel oil ratio of 220 g/Kw.h. Generally, when an excavator with a bucket capacity of 1.6m for carrying out heavy planting is used for arranging the safety retaining wall, the power is about 200Kw, the oil consumption Gt of the excavator is =200 Kw × 220 g/Kw.h ÷ 1000=44kg/h, namely the oil consumption is 44kg/h ÷ 0.85kg/L =51.8L/h, the excavator needs to work for 5h and consumes 5h × 51.8L/h =259L of diesel oil when processing a 100m safety retaining wall. Use the utility model discloses the oil consumption that carries out the operation calculates: the loader power for 3m transportation is about 162KW, the oil consumption Gt =162 Kw × 220 g/Kw.h ÷ 1000=35.6kg/h, namely the oil consumption is 35.6kg/h ÷ 0.85kg/L =41.9L/h, and 2h × 41.9L/h =83.8L of diesel oil is consumed when a loader is operated for 2h when a 100m safety retaining wall is processed. Therefore, the utility model discloses with installation cooperation operation before wheeled, can obviously reduce the energy consumption.
Utilize the utility model discloses construct safe barricade, easy operation, the energy consumption is low, and safe barricade preparation is efficient, and economic benefits is showing.
