Description

Technical Field

[0001] This invention relates to a testing device, and more particularly to a testing device for large-angle slag discharge rolling of a belt conveyor, belonging to the field of material conveying equipment discharge testing equipment design and manufacturing technology. Background Technology

[0002] In long-distance belt conveyor transportation and related engineering applications, large-angle lifting belt conveyors present numerous technical challenges in transporting large-diameter loose materials. Currently, the uneven particle size and high proportion of large-diameter particles generated by drill-and-blast excavation pose a serious challenge to the stable operation of belt conveyors. When transporting such materials, large-angle lifting belt conveyors often experience reduced transport intensity and relative displacement between material particles and the belt. Dynamic behaviors such as material sliding, rolling, accumulation, and jumping can affect the stability, belt speed, bending, and wear of the conveyor, reducing transport efficiency and potentially leading to equipment damage and increased energy consumption. Existing large-angle belt conveyor slag roll-off test devices lack the ability to adjust the tilt angle of the slag roll-off, making it impossible to simulate real working conditions. Consequently, it is difficult to grasp the movement patterns of materials under different working conditions and provide accurate data for optimizing transport processes and equipment parameters. Therefore, designing a large-angle belt conveyor slag roll-off test device has become an urgent technical problem for those skilled in the art. Summary of the Invention

The test device includes a belt conveyor body, a supporting base frame 1, and a slag-receiving space adjustment structure. The belt conveyor body is movably arranged on the supporting base frame 1 via the slag-receiving space adjustment structure. During the slag roll-off test, the three-dimensional spatial position of the belt conveyor body in slag receiving and slag discharge is determined by adjusting the slag-receiving space adjustment structure. The technical solution provided in this application is based on a belt conveyor body. The test device of this application is constructed by adding a supporting base frame 1 and a slag-receiving space adjustment structure, and the belt conveyor body is movably arranged on the supporting base frame 1 via the slag-receiving space adjustment structure. Then, during the slag roll-off test, the three-dimensional spatial position of the belt conveyor body in slag receiving and slag discharge is determined by adjusting the slag-receiving space adjustment structure. Thus, since the three-dimensional spatial position of the belt conveyor body in receiving and discharging slag is not fixed when receiving the transported slag, but is adjusted according to the speed, direction, and position of the falling material, the accuracy and reliability of the slag receiving point can be effectively guaranteed, thereby effectively reducing the splashing and / or rolling of falling slag outside the receiving belt.

The power output end of the conveyor drive motor 6 is connected to the conveyor belt 4 through the arc-shaped conveyor support frame 5. The belt conveyor body is movably arranged on the slag receiving space adjustment structure via the arc-shaped conveyor support frame 5. That is, by improving the conveyor support frame 5 in the prior art to an arc-shaped structure, the unexpected splashing of falling material is minimized.

[0018] Accordingly, as a key component of this application's improvement, in order to simplify its structure, facilitate operation, and maximize the experimental effect while minimizing the rolling and splashing of the falling material, the slag receiving space adjustment structure of this application includes an installation and connection platform, a composite support assembly, and a slag receiving space adjustment installation assembly.

Based on the actual experimental conditions, the preferred method is that the installation and connection platform of this application includes a rectangular steel welding main platform 7 and a steel welding horizontal position adjustment sub-platform.

[0019] A more detailed structure is as follows: the upper support rod assembly of this application includes two upper support rods 8, the lower ends of which are fixedly connected to both sides of the front end of the rectangular steel welded main platform, and the upper ends of which are hinged to both sides of the material output end of the arc-shaped conveying support frame 5 via ball joints 19; the lower support rod assembly includes two lower support rods 9, the lower ends of which are fixedly connected to both ends of one side of the support base frame 1 along the length direction, and the upper ends of which are hinged to both ends of one side of the rectangular steel welded main platform 7 along the length direction; the middle and rear ends of the arc-shaped conveying support frame 5 are movably connected to the steel welded horizontal position adjustment sub-platform via a slag receiving space adjustment installation assembly; the other side of the rectangular steel welded main platform 7 along the length direction is movably connected to the other side of the support base frame 1 along the length direction via a slag receiving space adjustment installation assembly. The main platform tilt angle adjustment assembly of this application includes two sets of servo hydraulic cylinders 10. At each end of the rectangular steel welded main platform 7 along its length, a set of servo hydraulic cylinders 10 provides adjustable tilt angle support on the other end of the support base 1 along its length. The conveyor support frame tilt and horizontal position adjustment assembly of this application includes two sets of adjusting screws and two sets of supporting hinge rods. The steel welded horizontal position adjustment sub-platform includes two L-shaped steel welded frames. Each L-shaped steel welded frame extends horizontally along its short side 11 and long side 12 on both sides of the rear of the rectangular steel welded main platform. The two sets of adjusting screws are respectively arranged on the long side 12 of the two L-shaped steel welded frames. The lower ends of the two sets of supporting hinge rods are screwed to the corresponding adjusting screws, and the upper ends of the two sets of supporting hinge rods are hinged to both sides of the rear of the arc-shaped conveyor support frame. Each set of adjusting screws includes a drive motor 13, a ball screw 14, and a screw mounting block assembly 15. Each ball screw 14 is mounted on the upper part of the long side of two L-shaped steel welded frames along the length direction via the screw mounting block assembly 15.

[0020] This application restricts the angle of the belt conveyor before and after raising it according to the driving equipment, such as the angle of the conveyor belt body, which is limited by the ball screw, square nut and adjusting rod, thereby avoiding jamming during the adjustment of the belt conveyor tilt angle.

[0021] In summary, the technical solution provided in this application also has the following advantages: 1. This experimental device uses the output shaft of a servo motor to drive a ball screw to rotate. The ball screw drives a square nut to slide on the surface of a guide frame. The square nut drives an adjusting rod to slide synchronously. During the sliding process, the other side of the adjusting rod is rotatably connected to the side frame of the conveyor belt. The adjusting rod rotates, causing the side frame of the conveyor belt to rotate on the second support rod, thereby changing the angle of the side frame and thus the angle at which the conveyor belt transports materials. By adjusting the angle at which the conveyor belt transports materials, the transportation environment in different areas can be simulated, thereby understanding the movement pattern of materials and providing accurate basis for optimizing transportation processes and equipment parameters.

[0022] 2. This experimental device drives the adjusting frame to rotate on the first support rod via the piston rod of a servo hydraulic cylinder. The servo hydraulic cylinder also supports the adjusting frame through rotation. At this time, the angle of the adjusting frame on the support base tilts. The adjusting frame, through the second support rod and the adjusting rod, changes the angle between the conveyor belt side frame and the conveyor belt body, causing the entire conveyor belt body to tilt. This tilting of the conveyor belt body helps it overcome centrifugal force during material transport. The tilt angle of the conveyor belt body against centrifugal force can be adjusted according to the speed of material transport, the transport angle, and the size of the material being transported, providing more effective data for actual material transport.

[0023] The technical solution of this application will be further described below through specific embodiments: The purpose of this invention is to provide a test device for the slag roll-off of a large-angle belt conveyor, in order to solve the problem mentioned in the background art that the existing test devices for the slag roll-off of large-angle belt conveyors lack the ability to adjust the tilt angle of the slag roll-off, cannot simulate real working conditions, and therefore cannot grasp the movement law of materials under different working conditions, and cannot provide accurate basis for optimizing the transportation process and equipment parameters.

[0024] To achieve the above objectives, the present invention provides the following technical solution: a test device for slag roll-off of a large-angle belt conveyor; comprising a conveyor belt side frame, on the surface of which a conveyor belt body is disposed; an adjustment mechanism is disposed at the bottom of which an adjustment mechanism is provided; the adjustment mechanism includes a support base frame disposed at the bottom of which a first support rod is fixedly connected; an adjustment frame is rotatably connected to the surface of the first support rod; a servo hydraulic cylinder is rotatably connected to the surface of the support base frame; the piston rod of the servo hydraulic cylinder is rotatably connected to the bottom of the adjustment frame; and the adjustment frame is rotatably connected to the surface of which a servo hydraulic cylinder is disposed. A guide frame is fixedly connected, a servo motor is fixedly connected to the surface of the guide frame, a ball screw is fixedly connected to the output shaft of the servo motor, a square nut is threaded onto the surface of the ball screw, an adjusting rod is rotatably connected to the surface of the square nut, a connecting rod is fixedly connected to the surface of the conveyor belt side frame, the end of the adjusting rod away from the connecting rod is rotatably connected to the surface of the connecting rod, a second support rod is fixedly connected to the surface of the adjusting frame, one end of the conveyor belt side frame is rotatably connected to the top of the second support rod, a material box is provided on one side of the support base, and casters are fixedly installed at the bottom of the material box.

[0025] The conveyor belt side frame and the conveyor belt body are arc-shaped. The conveyor belt side frame and the conveyor belt body are rotatably connected to the surface of the adjustment frame through the second support rod. The adjustment frame as a whole is arc-shaped.

[0026] The guide frame is provided in two sets, and the two sets of guide frames are parallel to each other. The servo motor drives the ball screw to rotate on the guide frame through the output shaft. The ball screw drives the square nut to slide on the surface of the guide frame through rotation.

[0027] The adjusting rods are provided in two sets. One set of adjusting rods is rotatably connected to the bottom of the conveyor belt side frame, and the other set of adjusting rods is rotatably connected to the surface of the connecting rod. The square nut on the guide frame supports the conveyor belt body through the adjusting rods.

[0028] The square nut moves synchronously with the adjusting rod during its movement, and the adjusting rod rotates on the adjusting frame to drive the conveyor belt side frame and the conveyor belt body to rotate during its movement.

[0029] The support base is generally arc-shaped. The adjustment frame rotates on the support base via a first support rod. The servo hydraulic cylinder drives the adjustment frame to rotate on the support base via a piston rod.

[0030] The adjusting frame drives the conveyor belt side frame to rotate via the adjusting rod and the second support rod, and the conveyor belt side frame drives the conveyor belt body to rotate synchronously.

[0031] Example 1 if Figure 1-5 As shown, this application provides one embodiment: A test device for slag roll-off from a large-angle belt conveyor includes a conveyor belt side frame, a conveyor belt body mounted on the surface of the side frame, and drive motors installed on the side frame and the conveyor belt body to facilitate material transport by the conveyor belt body. An adjustment mechanism is located at the bottom of the side frame, comprising a support base frame positioned at the bottom of the side frame. A first support rod is fixedly connected to the surface of the support base frame, and an adjustment frame is rotatably connected to the surface of the first support rod. A servo hydraulic cylinder is rotatably connected to the surface of the support base frame, with its piston rod rotatably connected to the bottom of the adjustment frame. A guide frame is fixedly connected to the surface of the adjustment frame, and a servo motor is fixedly connected to the surface of the guide frame. A ball screw is fixedly connected to the output shaft of the servo motor, and a square nut is threaded onto the surface of the ball screw. The system includes an adjusting rod and a connecting rod fixedly connected to the surface of the conveyor belt side frame. The end of the adjusting rod away from the connecting rod is rotatably connected to the surface of the connecting rod. A second support rod is fixedly connected to the surface of the adjusting frame. One end of the conveyor belt side frame is rotatably connected to the top of the second support rod. A material box is installed on one side of the support base frame, and casters are fixedly installed at the bottom of the material box. The test material will fall onto the material box, which is conveniently transported by the casters. This adjusting mechanism can adjust one end of the conveyor belt side frame and the conveyor belt body, thereby adjusting the tilt angle of the conveyor belt side frame and the conveyor belt body to simulate the transportation environment in different areas. At the same time, this adjusting mechanism can also adjust the angle of one side of the conveyor belt side frame and the conveyor belt body to simulate the angle at which the material can just overcome the centrifugal force of the conveyor belt body transporting the material.

[0032] The conveyor belt side frame and the conveyor belt body are arc-shaped. During the material transport process, the conveyor belt body generates centrifugal force. With different transport speeds and different types of materials, the material may detach under the influence of centrifugal force. Therefore, the height of one side of the conveyor belt side frame and the conveyor belt body needs to be continuously adjusted to test the optimal tilt angle at which the centrifugal force during material transport can be perfectly overcome. The conveyor belt side frame and the conveyor belt body are rotatably connected to the surface of the adjusting frame via a second support rod. The adjusting frame is arc-shaped. Rotation of the conveyor belt side frame and the conveyor belt body changes the angle at which the conveyor belt transports materials. Transporting materials at different tilt angles and with materials of different sizes will result in different test conditions on the conveyor belt body. By continuously adjusting the tilt angle and conveyor speed of the conveyor belt body, the optimal data for material transport can be found.

[0033] There are two sets of guide frames, which are parallel to each other. The servo motor drives the ball screw to rotate on the guide frame through the output shaft. There are two sets of servo motors, which are controlled by a control system to ensure that the output shafts of the servo motors rotate synchronously. The ball screw drives the square nut to slide on the surface of the guide frame through rotation. After the ball screw has rotated, it will automatically lock the position of the square nut on the guide frame, thereby ensuring the stable support of the adjusting rod for the side frame of the conveyor belt.

[0034] There are two sets of adjusting rods. One set of adjusting rods is rotatably connected to the bottom of the conveyor belt side frame, and the other set of adjusting rods is rotatably connected to the surface of the connecting rod. Since the conveyor belt side frame and the conveyor belt body are arc-shaped, the connecting rod can connect to the other set of adjusting rods, ensuring that the two sets of adjusting rods provide stable support for the conveyor belt side frame and the conveyor belt body. The square nut on the guide frame supports the conveyor belt body through the adjusting rod, thereby preventing the position of the conveyor belt side frame and the conveyor belt body from shifting.

[0035] As the square nut moves, it drives the adjusting rod to move synchronously. During the movement, the adjusting rod rotates to drive the conveyor belt side frame and the conveyor belt body to rotate on the adjusting frame. By continuously changing the tilt angle of the conveyor belt side frame and the conveyor belt body, the test device can simulate more test environments.

[0036] The support base is arc-shaped. The adjustment frame rotates on the support base via the first support rod. The servo hydraulic cylinder drives the adjustment frame to rotate on the support base via the piston rod. The servo hydraulic cylinder can precisely change the tilt angle of the adjustment frame on the support base via the piston rod, and ensure the stability of the adjustment frame on the support base.

[0037] The adjusting frame drives the side frame of the conveyor belt to rotate via the adjusting rod and the second support rod. The side frame of the conveyor belt drives the main body of the conveyor belt to rotate synchronously. After rotation, the main body of the conveyor belt can overcome the centrifugal force of the material being transported. The angle at which the main body of the conveyor belt overcomes the centrifugal force can be adjusted according to the speed of the material being transported, the transport angle, and the different sizes of the material being transported, providing more effective data for the actual material transport.

[0038] Working principle: During the material transport process of the conveyor belt, the output shaft of the servo motor drives the ball screw to rotate. The ball screw drives the square nut to slide on the surface of the guide frame. The square nut drives the adjusting rod to slide synchronously. During the sliding process, since the other side of the adjusting rod is rotatably connected to the side frame of the conveyor belt, the adjusting rod will rotate and drive the side frame of the conveyor belt to rotate on the second support rod, thereby changing the angle of the side frame of the conveyor belt, and thus changing the angle of the material transported by the conveyor belt. By adjusting the angle of the material transported by the conveyor belt, the transportation environment of different areas can be simulated, thereby understanding the movement law of the material and providing a precise basis for optimizing the transportation process and equipment parameters.

[0039] The piston rod of the servo hydraulic cylinder drives the adjusting frame to rotate on the first support rod, and the servo hydraulic cylinder also supports the adjusting frame by rotating. At this time, the angle of the adjusting frame on the support base is tilted. The adjusting frame changes the angle between the conveyor belt side frame and the conveyor belt body through the second support rod and the adjusting rod, so that the entire conveyor belt body tilts to the side. The tilt of the conveyor belt body makes the conveyor belt body overcome centrifugal force in transporting materials. The tilt angle of the conveyor belt body to overcome centrifugal force can be adjusted according to the speed of the conveyor belt body transporting materials, the transport angle, and the different sizes of materials being transported, so as to provide more effective data for the actual transport of materials.
