Description

Technical Field

[0001] The utility model relates to a conveyor group steering mechanism for a dredging and conveying vehicle, belonging to the field of machinery. Background Art

[0002] The coal mine water bunker is one of the essential key facilities of all coal mines. In order to ensure that the mine water bunker has the necessary water storage capacity and ensure the production safety of the coal mine, the cleaning of the coal slime in the water bunker is an important and regular task. At present, the cleaning of the coal slime in the water bunker mainly relies on the cleaning and conveying vehicles in the bunker to collect the coal slime and transport it to the coal slime dehydration equipment installed outside the bunker for dehydration. In the past, the cleaning and conveying vehicles could only be lifted and lowered by two sets of lifting cylinders. When cleaning the coal slime around the vehicle body, the overall position of the cleaning and conveying vehicle must be moved and adjusted to clean it. This is time-consuming and labor-intensive, and the operation is troublesome, and it also increases the cleaning cost. Summary of the invention

[0003] In view of the deficiencies in the prior art, the utility model provides a steering mechanism for a conveyor unit for a dredging and conveying vehicle, which solves the problems raised in the above background technology.

[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions: a conveyor unit steering mechanism for a dredging and conveying vehicle, comprising:

[0005] A lateral steering mechanism, used to control the lateral swing of the conveyor group;

[0006] A lifting mechanism, used to control the conveyor unit to complete the lifting action;

[0007] The conveyor unit is movably assembled on the hopper of the excavation and conveying vehicle through the lateral steering mechanism and the lifting mechanism.

[0008] Further, the lateral steering mechanism comprises: a lateral bogie and two hydraulic cylinders, the cylinder ends of the two hydraulic cylinders are connected to the two sides of the hopper through pins, and the piston rod ends of the two hydraulic cylinders are connected to the two ends of the lateral bogie through pins, so as to push the lateral bogie to rotate; the lateral bogie is rotatably mounted on the hopper, and the conveyor unit is supported on the lateral bogie through pins;

[0009] The lifting mechanism includes: a lifting bogie and a lifting cylinder, the cylinder end of the lifting cylinder is connected to the lifting bogie through a pin shaft, and the piston rod end of the lifting cylinder is connected to the bottom end of the conveying unit through a pin shaft; the lifting bogie is rotatably mounted on the lower end of the hopper through a pin column.

[0010] Furthermore, the lateral bogie and the lifting bogie rotate synchronously, and their rotation axes coincide with each other.

[0011] Due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0012] The structure is simple and more flexible. Through the joint action of the lateral steering mechanism and the lifting mechanism, the conveying unit can realize lateral left and right swings and up and down lifting movements within a certain range, so that the excavation and conveying vehicle can better adapt to the water tank terrain and collect and transport the coal slime around the excavation and conveying vehicle in the water tank to the maximum extent.

Implementation

[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1 and Figure 2 As shown, the utility model is a conveyor group steering mechanism for a dredging and conveying vehicle, comprising:

[0018] The lateral steering mechanism 1 is used to control the lateral swing of the conveyor unit 2; the lifting mechanism 3 is used to control the conveyor unit 2 to complete the lifting action;

[0019] The conveyor unit 2 is movably assembled on the hopper 4 of the excavation and conveying vehicle through a lateral steering mechanism 1 and a lifting mechanism 3 .

[0020] The lateral steering mechanism 1 includes: a lateral bogie 104 and two hydraulic cylinders (101 / 102), the cylinder bodies 101 ends of the two hydraulic cylinders are connected to the two sides of the hopper 4 through pins 105, and the piston rods 102 ends of the two hydraulic cylinders are connected to the two ends of the lateral bogie 104 through pins 103, which are used to push the lateral bogie 104 to rotate; the lateral bogie 104 can be rotatably installed on the hopper 4, and the conveyor unit 2 is supported on the lateral bogie by two pins 103.

[0021] The lifting mechanism includes 3: a lifting bogie 301 and a lifting cylinder (303 / 304), the end of the lifting cylinder body 303 is connected to the lifting bogie 301 through a pin shaft 302, and the end of the lifting cylinder piston rod 304 is connected to the bottom end of the conveying unit 2 through a pin shaft 302; the lifting bogie 301 is rotatably installed at the lower end of the hopper 4 through a pin column 305.

[0022] The lateral bogie 104 and the lifting bogie 301 rotate synchronously, and the rotation axes coincide.

[0023] In summary, the working process of the utility model is:

[0024] Drive the excavation and conveying vehicle to the silo, and the conveying unit 2 collects and conveys the coal slime. By controlling the extension and contraction of the two hydraulic cylinders in the lateral steering mechanism 1, the lateral bogie 104 is pushed to rotate horizontally left and right, thereby driving the conveying unit 2 to swing horizontally. When the conveying unit 2 rotates horizontally, the lifting mechanism 3 also swings horizontally with the conveying unit 2. By controlling the extension and contraction of the hydraulic cylinder in the lifting mechanism 3, the conveying unit 2 is pushed to complete the lifting action, so as to better adapt to the uneven coal slime in the silo. Through the continuous cooperation of the lateral steering mechanism 1 and the lifting mechanism 3, the conveying unit 2 can collect the coal slime around the excavation and conveying vehicle in the silo to the maximum extent, and transport it to the hopper 4.

[0025] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
