Description

Technical Field

[0001] This invention relates to the field of installation technology for mining belt conveyors, and more specifically, to an installation device for the legs and longitudinal beams of a mining belt conveyor. Background Technology

[0002] Coal mine tunneling faces typically have roadways several thousand or even tens of thousands of meters long. As the roadways advance, belt conveyors need to be continuously extended to ensure continuous transport, necessitating a constant increase in the number of outriggers and longitudinal beams. In roadways thousands to tens of thousands of meters long, a set of outriggers and longitudinal beams needs to be installed every 3 meters to ensure the normal operation of the belt conveyor. This work is extremely tedious and labor-intensive. Currently, the conservative daily advance of a coal mine tunneling face is only a dozen meters, sometimes reaching tens or even hundreds of meters. During this time, at least three sets of outriggers and longitudinal beams need to be installed. Currently, there is no equipment available for installing outriggers and longitudinal beams in coal mines, so installation must be done manually. The entire installation process requires four operators, and it takes approximately 30 minutes to install one set of outriggers and longitudinal beams. While the installation of outriggers and longitudinal beams may seem simple, it consumes a significant amount of manpower and time and needs to be repeated daily, severely impacting project schedules and production efficiency. This is a pressing problem that urgently needs to be solved in coal mine tunneling faces. Summary of the Invention

[0003] In order to overcome the shortcomings of existing technologies, a mining belt conveyor support leg and longitudinal beam installation device is provided, which reduces the intensity of manual labor, improves production efficiency, and increases the mechanization of tunneling faces.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] A device for installing legs and longitudinal beams of a mining belt conveyor, comprising:

[0006] The main frame has walking tracks on both sides at the lower end, and a longitudinal beam installation device in the middle of the main frame.

[0007] The outrigger storage device includes a frame and a rail for suspending the outrigger to be installed. The frame is located at one end of the main frame, and the rail is fixedly located at the upper end of the frame.

[0008] The outrigger pushing device is located on the side of the outrigger storage device near the longitudinal beam mounting device. It includes a linear drive device I and a clamping cylinder I for clamping the outrigger. The clamping cylinder I is located on the working end of the linear drive device I. The linear drive device I is used to move the outrigger clamped by the clamping cylinder I to the installation position.

[0009] The longitudinal beam storage device is located at the end of the main frame away from the outrigger storage device, and is used to store longitudinal beams;

[0010] The longitudinal beam moving device is located at the lower end of the longitudinal beam storage device and includes a clamping mechanism and a linear drive device II. The clamping mechanism is located at the movable end of the linear drive device II. The clamping mechanism clamps the longitudinal beam, and the linear drive device II moves the longitudinal beam to the installation position.

[0011] Furthermore, the longitudinal beam installation device includes a fixed frame, a translational frame, a rotating frame, and a clamping device. The fixed frame is fixedly connected to the main frame. The translational frame is slidably mounted on the fixed frame and connected to a linear drive device III. The rotating frame is rotatably mounted at the lower end of the translational frame. A rotary cylinder is provided between the rotating frame and the translational frame. The clamping device is mounted at the lower end of the rotating frame via a lifting cylinder.

[0012] Furthermore, a linear track is provided at the lower end of the rotating frame, the clamping device is slidably mounted on the linear track, and a linear drive device IV is provided between the clamping device and the linear track.

[0013] Furthermore, the clamping device includes two sets of clamping cylinders II disposed on both sides of the rotating frame.

[0014] Furthermore, a slider is provided at the lower end of the frame in a direction perpendicular to the main frame, and the slider is connected to a side-push cylinder I.

[0015] Furthermore, the longitudinal beam storage device includes a lifting device, a side-push cylinder II, and a longitudinal beam gripper assembly. The fixed end of the lifting device is located at the end of the main frame away from the outrigger storage device, and the movable end of the lifting device extends downward and is fixedly connected to a side-push rail. The longitudinal beam gripper assembly is slidably disposed in the side-push rail, and a side-push cylinder II is disposed between the longitudinal beam gripper assembly and the side-push rail.

[0016] Furthermore, a lifting cylinder is provided on the side of the main frame near the longitudinal beam pushing device. The fixed end of the lifting cylinder is fixedly connected to the main frame, and the movable end of the lifting cylinder is connected to the longitudinal beam pushing device.

[0017] Furthermore, the main frame is equipped with an upper belt lifting cylinder and a lower belt lifting cylinder.

[0018] Furthermore, the main frame is provided with a support leg track, which is located at the lower end of the longitudinal beam mounting device, with one end of the support leg track extending toward and connecting with the support leg storage device.

[0019] Furthermore, the linear drive device I and linear drive device II are lead screw transmission devices.

[0020] Working principle:

[0021] After installation, the equipment straddles the belt conveyor. The outrigger tracks are connected to a set of outriggers on the belt conveyor at pre-set positions, and the four walking tracks are in contact with the ground. During operation, the longitudinal beams and outriggers are prepared first. The longitudinal beam storage device is pushed out laterally by side-push cylinder II, then lowered to near the ground by a lifting device. Then, the four sets of longitudinal beams are manually placed onto the storage device. After placement, the lifting device and side-push cylinder II move the storage device back to its original position, completing the storage of the longitudinal beam sets. The upper and lower belt lifting cylinders respectively lift the upper and lower belts of the belt conveyor to create space for the outriggers to pass laterally. The outrigger storage device is pushed out laterally by side-push cylinder I, and then the four sets of outriggers are manually placed onto it. After placement, side-push cylinder I moves the storage device back to its original position, and the upper and lower belt lifting cylinders then move the upper and lower belts back to their original positions, completing the storage of the outrigger sets.

[0022] Installation begins with the lower belt lifting cylinder raising the lower belt of the belt conveyor to create space for the outriggers to pass longitudinally. Then, the clamping cylinder I of the outrigger pushing device moves to the outrigger storage device via a screw drive and clamps a set of outriggers. The outriggers, along the outrigger track, are moved to their designated positions on the outrigger pushing device via the screw drive, awaiting installation. The lower belt of the belt conveyor is then pushed back to its original position. The lifting cylinder first raises the longitudinal beam pushing device to a certain height from the longitudinal beam storage device. Then, the clamping mechanism of the longitudinal beam pushing device clamps a set of longitudinal beams from the longitudinal beam storage device. Finally, the lifting cylinder pushes the longitudinal beam pushing device back to its original position. The longitudinal beam pushing device moves the longitudinal beam assembly forward to the designated position via linear drive device II. Then, the longitudinal beam installation device clamps the longitudinal beam assembly delivered by the pushing device using lifting and clamping cylinders II. The installation device then moves the longitudinal beam assembly laterally via linear drive device III. Next, the upper belt lifting cylinder raises the belt conveyor to create space for the longitudinal beam assembly to pass laterally. Then, the linear drive device III of the installation device retracts the longitudinal beam assembly to the designated position above the outrigger assembly. Finally, the lifting cylinder of the installation device installs the longitudinal beam assembly onto the outrigger assembly. The upper belt lifting cylinder then moves the belt conveyor back to its original position. Once one set of outrigger and longitudinal beam assemblies is installed, the equipment moves forward, and the cycle repeats to install the next set. The entire process of material preparation, movement, and installation is repeated after all four sets of outrigger and longitudinal beam assemblies have been used.

[0023] The beneficial effects of this invention compared to the prior art are as follows:

[0024] This invention includes a longitudinal beam installation device, a longitudinal beam storage device, a leg storage device, a longitudinal beam pushing device, and a leg pushing device. Through the cooperation of the longitudinal beam storage device and the longitudinal beam pushing device, and the cooperation of the leg storage device and the leg pushing device, automatic material handling and installation of the longitudinal beams and legs are achieved. The longitudinal beam installation device automatically clamps the longitudinal beams conveyed by the longitudinal beam pushing device, thus achieving automatic installation of the longitudinal beams. This eliminates the need for excessive operator intervention, reduces labor intensity, improves production efficiency, and enhances the mechanization level of the tunneling face.
