For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0036] Vibrating conveyors transport materials by means of a motor outputting torque and speed, which drives an eccentric shaft to rotate. The eccentric shaft, through a push-pull rod, drives a balance beam to swing, and the balance beam, through a rocker arm, causes the conveyor trough to vibrate. The material conveying capacity is positively correlated with the vibration frequency and amplitude of the trough. The optimal operating state for a vibrating conveyor is when the center line of the rocker arm forms a 60° angle with the frame. At this angle, the parabolic angle and parabolic distance of the conveyed material are optimal.
[0037] To ensure optimal parabolic angle and distance for materials conveyed by the vibrating conveyor, appropriate testing tools are needed to inspect and verify its condition after equipment maintenance. To improve maintenance efficiency and equipment operational stability, this invention, based on vibrating conveyor structural design standards, designs and invents a vibrating conveyor condition testing tool. This tool detects the conformity of the angle between the rocker arm and the frame's reference plane, and adjusts the angle accordingly to ensure the vibrating conveyor's performance meets design requirements, thereby extending the lifespan of the vibrating conveyor and its related components.
[0038] Example 1
[0039] As shown in Figure 1, in a typical embodiment of this utility model, this embodiment discloses a tool suitable for condition detection of vibrating conveyors in the tobacco industry, including: a positioning screw hole shaft 2, a right-angle triangle plate 1, a frame axis parallel base plate 3, a sliding wedge 4, an adjustable wedge clamp 5, and a right-angle ruler 6.
[0040] The positioning screw hole shaft 2 is used to install on the rocker arm to provide a positioning base for the testing tool; the right-angle triangle 1 is used to install on the positioning screw hole shaft 2, with the first acute angle facing upwards; the frame axis parallel base plate 3 and the sliding wedge 4 are used to install in the gap between the vibrating conveyor balance beam and the frame, with the frame axis parallel base plate 3 located directly below the right-angle side corresponding to the second acute angle of the right-angle triangle 1, and the sliding wedge 4 located below the frame axis parallel base plate 3, used to cooperate with the adjustable wedge clamp 5 to adjust the upper plane of the frame axis parallel base plate 3 to fit with the lower plane of the frame; the right-angle ruler 6 is placed on the frame axis parallel base plate 3 to check whether the rocker arm is in the optimal installation state.
[0041] Specifically, since the optimal parabolic angle and distance for the material conveyed by the vibrating conveyor are achieved when the center line of the rocker arm forms a 60° angle with the frame, as shown in Figure 2, the right-angled triangle 1 in this embodiment is designed based on a right-angled triangle with angles of 30°-60°-90°, with 30° as the first acute angle and 60° as the second acute angle. During installation, installing the triangle with the 30° angle facing upwards allows the angle between the center line of the rocker arm and the frame to correspond to the 60° angle on the right-angled triangle 1, enabling rapid detection of the angle between the center line of the rocker arm and the frame.
[0042] As shown in Figure 3, in this embodiment, one end of the positioning screw hole shaft 2 is a nut structure, and the other end is a shaft structure; the nut structure is the same size as the locking nut used on the rocker arm. During testing, any rocker arm on the vibrating conveyor is selected, the locking nut on the rocker arm is removed, and the nut structure part of the positioning screw hole shaft 2 is installed on the rocker arm. The right-angled triangle 1 is installed on the shaft structure of the positioning screw hole shaft 2. There are two positioning screw hole shafts 2, one installed on the mounting screw shaft between the rocker arm and the balance beam of the vibrating conveyor, and the other installed on the mounting screw shaft between the rocker arm and the trough, which can realize the positioning function using the hypotenuse of the right-angled triangle 1.
[0043] To ensure accurate positioning of the hypotenuse of the right-angled triangle 1, in this embodiment, the length of the hypotenuse of the right-angled triangle 1 is greater than the installation distance between the two positioning screw hole shafts 2. This ensures that the condition detection of the vibrating conveyor can be achieved using a single right-angled triangle 1.
[0044] To facilitate installation and make it applicable to the testing of various types of vibratory conveyors, in this embodiment, a positioning hole and an mounting elongated hole are made along the hypotenuse of the right-angled triangle plate 1. The size of the positioning hole matches the size of the shaft of the positioning screw hole 2, and the mounting elongated hole is parallel to the hypotenuse. This allows it to remain applicable even when the distances between the two positioning screw hole shafts 2 are different, thus improving the practicality and applicability of the tool.
[0045] In this embodiment, the right-angle ruler 6 includes a base ruler and a secondary ruler. During testing, the base ruler is placed on the base plate 3 parallel to the frame axis and is fully fitted to the base plate 3. The secondary ruler is fitted to the right-angled side corresponding to the 60° angle of the right-angled triangle 1. Under the optimal installation condition of the rocker arm, there should be no gap between the secondary ruler and the right-angled triangle 1 along the entire contact length. If there is a gap between the secondary ruler of the right-angle ruler 6 and the right-angled triangle 1 along the entire contact length, the height of the sliding wedge 4 can be adjusted by adjusting the adjustable wedge clamp 5 to finely adjust the gap between the balance beam and the vibrating conveyor frame until the secondary ruler of the right-angle ruler 6 and the triangle 1 are fitted without gaps along the entire contact length. This state is the optimal installation condition of the rocker arm.
[0046] During the adjustment of the balance beam and the vibrating conveyor frame, the sliding wedge 4 moves laterally under the action of the clamps. During this process, the height of the sliding wedge 4 increases. While ensuring the height adjustment function is met, the force exerted by the clamps on the adjustable wedge should be minimized as much as possible. Since a larger angle of the sliding wedge 4 results in a larger component force in the height direction, and a greater resistance during clamp adjustment, in this embodiment, the angle of the sliding wedge 4 is set to 15° to ensure its adjustment performance.
[0047] As shown in Figure 4, the sliding wedge 4 consists of two parts, namely, the upper wedge as shown in Figure 4(a) and the lower wedge as shown in Figure 4(b). The inclined surfaces of the upper and lower wedges slide relative to each other, raising the height of the working surface. If there are no relevant guide settings on the inclined surfaces of the wedges during the raising process, the two wedges may slip off course and become ineffective during the sliding process. Therefore, in this embodiment, guide grooves are provided on the inclined surfaces of the sliding wedge 4 to ensure that the adjustment of the sliding wedge 4 is effective.
[0048] As shown in Figure 5, in this embodiment, the adjustable wedge caliper 5 consists of a caliper body and a caliper bolt. As shown in Figure 5(a), the caliper body is n-shaped with different heights at both ends. The higher end has a screw hole with an internal thread that matches the thread of the caliper bolt. The other end has a bend that abuts against the vertical end face of the upper wedge of the sliding wedge 4 during use. As shown in Figure 5(b), the caliper bolt has a hexagonal head, and the length of the bolt shank is greater than the length of the caliper body. During use, the bolt shank is screwed into the screw hole of the caliper body, the bend end of the caliper body abuts against the vertical end face of the upper wedge of the sliding wedge 4, and the front end of the bolt shank abuts against the vertical end face of the lower wedge of the sliding wedge 4. The caliper bolt is turned with a wrench, and the rotation of the adjusting screw of the adjustable wedge caliper causes the upper and lower wedges to move relative to each other along the guide groove, thereby realizing the adjustment process of the sliding wedge 4.
[0049] As shown in Figure 6, in this embodiment, the frame axis parallel to the base plate 3 is provided with three through holes, which are connected to the upper wedge of the sliding wedge 4 by M6 bolts and used in combination with the lower wedge.
[0050] The specific implementation process of using a tool suitable for condition detection of vibrating conveyors in the tobacco industry, as described in this embodiment, is as follows:
[0051] (1) Select any rocker arm on the vibratory conveyor, loosen the locking nut on the rocker arm, install the positioning screw hole shaft 2 on the screw where the locking nut is located, and install the right angle triangle 1 on the spindle with the 30° angle facing upward;
[0052] (2) Install the frame axis parallel base plate 3 and sliding wedge 4 in the gap between the balance beam and the frame of the vibrating conveyor, so that the upper plane of the frame axis parallel base plate 3 is in contact with the lower plane of the frame, and its position is directly below the right angle side corresponding to the 60° angle of the right triangle; the adjustable wedge clamp 5 ensures that the upper plane of the frame axis parallel base plate 3 is in contact with the lower plane of the frame.
[0053] (3) Place the base ruler of the right angle ruler 6 on the base plate and fit it completely. Fit the secondary ruler of the right angle ruler 6 with the right angle side corresponding to the 160° angle of the right angle triangle.
[0054] (4) If the vernier scale of the right angle ruler 6 is in contact with the right angle triangle 1 without any gap along the entire length, then the current state is the optimal installation state of the rocker arm; if there is a gap between the vernier scale of the right angle ruler 6 and the right angle triangle 1 along the entire length, the height of the sliding wedge 4 can be adjusted by adjusting the wedge clamp 5 to finely adjust the gap between the balance beam and the vibrating conveyor frame until the vernier scale of the right angle ruler 6 and the right angle triangle 1 are in contact without any gap and fit together.
[0055] (5) After adjusting the right-angle ruler 6 to make full contact with the right-angle triangle 1 without gaps, tighten all the locking nuts on the rocker arm to fix the rocker arm in the best installation state.
[0056] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
