Description

Technical Field

[0001] The invention relates to the field of coal comprehensive excavation equipment, and in particular to an automatic deviation-correcting and material-collecting device for a tunnel with a floating function. Background Art

[0002] With the development of open-pit coal mines in my country, due to the limitations of mining technology, there are a large number of unmined parts due to the construction technology in the production process of open-pit coal mines, and some coal resources have not been mined in time and are left in the marginal areas of the mining area. A large number of thin coal seam resources have been buried for a long time. These remaining coal resources are usually scattered and difficult to mine directly, so they are often ignored, resulting in huge waste. In some deep open-pit coal mines, the amount of thin coal seam resources is as high as 40%. Even if there was some mining in the early days, domestic mining areas only relied on blasting, simple tunneling machine mining, etc., which had poor safety and low efficiency. In order to minimize resource waste, efficient recovery is the key.

[0003] The existing roadway collecting device is difficult to fully collect thin coal seam resources, especially in narrow and complex roadways, where materials are easily missed. In addition, the existing roadway collecting device has a low degree of automation, and the direction of travel and the collecting process rely on manual operation control, which is time-consuming and inefficient. Summary of the invention

[0004] Purpose: In order to overcome the deficiencies in the prior art, the present invention provides a tunnel automatic deviation correction and material collection device with a floating function, which automatically adapts to tunnel ground changes during tunnel excavation and realizes precise control of the excavation process.

[0005] Technical solution: To solve the above technical problems, the technical solution adopted by the present invention is:

[0006] In a first aspect, the present application provides a laneway automatic deviation correction and material collection device with a floating function, comprising a shovel plate body, a side pin push shaft, a side push mechanism, an outer pin shaft, a side push cylinder and an inner pin shaft; The loading reducer assembly is installed on the shovel body, and includes a star wheel, a first power output shaft and a second power output shaft.

[0007] In some embodiments, the side push pin shaft includes a first side push pin shaft and a second side push pin shaft, the side push mechanism includes a first side push mechanism connected to the shovel plate body through the first side push pin shaft, and a second side push mechanism connected to the shovel plate body through the second side push pin shaft, the first side push mechanism and the second side push mechanism are mirror-arranged at one end of the side baffles on both sides of the shovel plate body close to the back plate.

[0008] In some embodiments, the side thrust cylinder includes a first side thrust cylinder and a second side thrust cylinder, which are symmetrically arranged on both sides of the shovel body, and are used to drive the side thrust mechanism to rotate and provide side thrust.

[0009] In some embodiments, a sensor is arranged on the side thrust mechanism to receive signals of the magnitude of the force acting on the side thrust mechanism. When the forces acting on the first side thrust mechanism and the second side thrust mechanism are unbalanced, the side thrust cylinder is pushed out to adjust the distribution of the forces on both sides.

[0010] Specifically, when the material collecting device is moving forward, the side push mechanism is in close contact with the hole wall and provides a reverse force. When deviation occurs, the sensor arranged on the side push mechanism receives a signal of unbalanced forces on both sides. At this time, the first side push cylinder and the second side push cylinder are pushed out synchronously and distribute the forces on both sides. During the repeated adjustment process, the material collecting device can achieve accurate and automatic deviation correction and move forward according to the original predetermined route.

[0011] In some embodiments, the material receiving device also includes a lifting and rotating pin shaft, and the lifting and rotating pin shaft is used to enable the material receiving device to rotate around the lifting and rotating pin shaft under the action of its own gravity, close to the ground, and actively adapt to changes in the tunnel ground.

[0012] In some embodiments, the material collecting device also includes a lifting cylinder, one end of which is installed on the shovel body, and the other end is installed on the frame, which is used to drive the material collecting device as a whole to lift and lower around the lifting rotating pin shaft, passively adapting to changes in the tunnel ground.

[0013] Therefore, the material collecting device can be raised and lowered actively or passively, has a floating function, can automatically adapt to changes in the tunnel ground while moving forward, and cooperate with the side-thrust mechanism to achieve precise control of the direction during tunnel excavation.

[0014] In some embodiments, the lifting cylinder includes a first lifting cylinder and a second lifting cylinder, which are symmetrically arranged on both sides of the shovel body to coordinately control the lifting and lowering of the entire material receiving device.

[0015] In some embodiments, the material receiving device further includes a first loading reducer assembly 21 and a second loading reducer assembly 22, which are arranged in a mirror image on the shovel body 1; The first loading reducer assembly 21 and the second loading reducer assembly 22 respectively include a star wheel, a first power output shaft and a second power output shaft. The star wheel collects the material and pushes the material into the transport trough 12 under the drive of the first power output shaft. The rotation directions of the star wheels in the first loading reducer assembly and the second loading reducer assembly are opposite.

[0016] In some embodiments, the material collecting device also includes a sprocket drive mechanism, which is located in the middle of the shovel body and is connected to the second power output shaft of the loading reducer assembly. It drives the sprocket to rotate under the drive of a single-sided or double-sided power source, and is used to drive the chain to convey the material in the transport trough.

[0017] This sprocket drive mechanism can keep the sprocket rotating even when the power on one side is lost, ensuring continuous transportation of materials.

[0018] In a second aspect, the present application provides a side coal mining machine, including the automatic deviation correction and material collecting device with floating function as described in the first aspect.

[0019] Beneficial effects: The automatic deviation correction and material collecting device with floating function provided in the present application has a simple structure, is equipped with a lifting cylinder, has a floating function, can automatically adapt to changes in the tunnel ground, stick close to the ground during the material collecting process, and reduce resource waste; the setting of the side thrust mechanism and the side thrust cylinder can automatically correct the deviation and adjust the forward direction during the tunnel excavation process, thereby realizing precise control of the excavation and improving safety.
