Description

Technical Field

[0001] The utility model relates to the field of coal mine transportation, in particular to a compacting device for a coal transport vehicle. Background Art

[0002] With the development of industrial scale, the demand for coal in production continues to expand. At the same time, coal truck transportation is the main way to transport coal from coal mines. However, during the process of loading coal, due to manual loading through loaders, it is inevitable that the coal in the cargo compartment will be uneven, which does not meet the transportation specifications. In this regard, generally during or after loading, manual operations are performed to level the coal on vehicles with excessive tonnage and uneven heights. However, manual coal leveling is labor-intensive, low in efficiency, and has major safety hazards, and the overall transportation cost is high.

[0003] In response to the high cost of manual coal leveling, patent document CN217322537U provides a coal leveling and compacting device, which is a gantry frame with a hydraulic lifting device. The hydraulic lifting device drives a flat plate to press down to compact the top of the coal, replacing the manual coal leveling operation, reducing labor costs and improving the efficiency of coal leveling and compacting.

[0004] However, in the existing coal flattening method as given in this scheme, the flattening device adopts a method of compacting downward with a top pressure plate. During the compaction process, since the top of the coal pile is higher than the car body and there is no obstruction from the side panels of the cargo compartment, as the pressure is pressed downward, the accumulated coal blocks will spread around and fall from the coal transport car, causing environmental pollution. The coal needs to be recovered and cleaned at any time, which also creates the risk of injuring workers. Summary of the invention

[0005] Aiming at the problem that coal blocks fall off due to top compaction of existing coal leveling devices, the utility model provides a compacting device for a coal transport vehicle.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is a coal truck compacting device, including a gantry, hangers are respectively arranged on both sides of the gantry, a flip mechanism is installed on the hanger, the lower end of the flip mechanism is hinged to the hanger, an electric telescopic mechanism is installed on the flip mechanism, one end of the electric telescopic mechanism is hinged to the middle part of the flip mechanism, the other end of the electric telescopic mechanism is hinged to the top of the gantry, and the hinge point between the electric telescopic mechanism and the gantry is located on the outside of the hanger. This solution arranges a flip mechanism on both sides of the gantry. After the coal truck drives under the gantry, the flip mechanisms on both sides move obliquely downward to compact the two sides of the coal pile obliquely downward. While compacting, it can also play a blocking role to prevent coal blocks from falling to both sides during the compaction process, making the coal pile flat while reducing pollution to the transportation environment.

[0007] Preferably, the hanger includes a first hanger vertical rod and a second hanger vertical rod, the upper ends of the first hanger vertical rod and the second hanger vertical rod are fixedly connected to the door frame, the lower ends of the first hanger vertical rod and the second hanger vertical rod are commonly connected to a hanger cross rod, and the flip mechanism is hinged on the hanger cross rod. The frame structure is easy to build and use.

[0008] Preferably, inclined rod frames are respectively provided on both sides of the door frame, and the inclined rod frames include a fixed cross frame, and two mutually parallel inclined plate frames are provided below the fixed cross frame. The inclined plate frames are perpendicular to the fixed cross frame, and reinforcing ribs are provided between the fixed cross frame and the inclined plate frames, and the electric telescopic mechanism is hinged between the two inclined plate frames.

[0009] Preferably, the electric telescopic mechanism comprises an electric telescopic rod, the main body of the electric telescopic rod is equipped with an electric telescopic rod sleeve, the electric telescopic rod sleeve is hinged to the inclined rod frame, the telescopic end of the electric telescopic rod is provided with a connecting mechanism, and the connecting mechanism is hinged to the flip mechanism.

[0010] Preferably, a compression bag is provided at one end of the main body of the electric telescopic rod, and the telescopic end of the electric telescopic rod passes through the compression bag, so as to protect the telescopic end of the electric telescopic rod and prevent the electric telescopic rod from being worn by debris such as coal slag.

[0011] Preferably, the connecting mechanism is U-shaped, including a connecting plate, one side of the connecting plate is fixedly connected to the telescopic end of the electric telescopic rod, and the other side of the connecting plate is provided with two mutually parallel fixed blocks. The flipping mechanism includes a flipping frame, and the middle part of the flipping frame is hinged between the two fixed blocks.

[0012] Preferably, the overturning mechanism further comprises a compacting roller, which is rotatably mounted on the upper part of the overturning frame via a fixed shaft. The roller structure is adopted, so that dynamic compaction can be performed as the coal truck moves forward.

[0013] Preferably, six groups of turnover mechanisms are provided, and the six groups of turnover mechanisms are symmetrically arranged on both sides of the door frame, and the turnover mechanisms on each side are arranged at equal intervals, and the upper end of the turnover frame is connected to the fixed block through a gear shaft. Multi-level compaction is formed to improve the compaction effect, and the compaction degree of each level can be changed in sections to avoid the problem of coal blocks piling up backwards due to excessive compaction at one time.

[0014] It can be seen from the above technical scheme that the advantages of the utility model are that it adopts the method of compacting obliquely downward on both sides, which can achieve a blocking effect while compacting, and form a trapezoidal structure on the top of the coal pile, which can prevent coal blocks from falling to both sides during the coal leveling process and subsequent transportation.

Figure 2 As shown, the hanger 2 includes a first hanger vertical rod 21 and a second hanger vertical rod 22, the upper ends of the first hanger vertical rod 21 and the second hanger vertical rod 22 are fixedly connected to the top of the door frame 1, and the lower ends of the first hanger vertical rod 21 and the second hanger vertical rod 22 are commonly connected to a hanger cross rod 23, and the hanger cross rod 23 is arranged along the traveling direction of the coal truck.

[0027] Three sets of turning mechanisms 6 are arranged on each side of the hanger crossbar 23.

An electric telescopic mechanism 5 is arranged between the turning frame 61 and the door frame 1, specifically, as shown in FIG. Figure 1-7 As shown, the electric telescopic mechanism 5 includes an electric telescopic rod 52, and an inclined rod frame 3 is also arranged at the position corresponding to the flip mechanism on each side of the top of the door frame 1. The inclined rod frame 3 is located on the upper and oblique side of the hanger 2. The inclined rod frame 3 includes a fixed cross frame 31, and two mutually parallel inclined plate frames 32 are arranged below the fixed cross frame 31. The inclined plate frames 32 are perpendicular to the fixed cross frame 31. A reinforcing rib 33 is arranged between the fixed cross frame 31 and the inclined plate frames 32. An electric telescopic rod sleeve 51 is arranged at the rear of the main body of the electric telescopic rod 52 near its driving motor 4. The retractable rod sleeve 51 is hingedly installed between the two inclined frame plates 32, and the hinge axis between the electric telescopic rod sleeve 51 and the inclined frame plate 32 is along the travel direction of the coal truck.
