Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for screening equipment, specifically to a flexible micro-adjustment hoisting mechanism. Background Technology

[0002] During the installation and use of screening equipment (such as vibrating screens and gyratory screens), the levelness of the rotary screening equipment directly affects the screening efficiency, the operational stability of transmission components (such as transmission blocks), and the service life of the equipment.

[0003] Traditional rotary screening equipment hoisting mechanisms have several problems: First, the installation process is cumbersome, often using rigid fixed structures that require multiple calibrations of the support positions, consuming a lot of time; second, adjustment is difficult, as it is hard to independently fine-tune the height of the four corners of the rotary screening equipment, often resulting in local level deviations due to overall adjustment, which in turn affects the balanced operation of the transmission blocks and the lateral level of the screen surface; third, replacement is inconvenient, as most components are welded or integral structures, requiring complete replacement when a local part is damaged, resulting in high maintenance costs.

[0004] Therefore, it is necessary to develop a flexible, fine-tuning hoisting mechanism that is easy to install, allows for independent fine-tuning of the height of the four corners of the rotary screening equipment, ensures transmission stability, and is easy to replace, in order to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to overcome the defects of the prior art and provide a flexible micro-adjustment hoisting mechanism to simplify the installation process and improve installation efficiency; it can independently fine-tune the height of the four corners of the rotary screening equipment to ensure the horizontal level of the screen surface and the balanced operation of the transmission blocks; each component is detachably connected for easy and quick replacement and maintenance.

[0006] The technical solution adopted by this utility model is as follows: a flexible fine-adjustment hoisting mechanism, including a fine-adjustment hoisting mechanism body installed on a support beam, characterized in that the fine-adjustment hoisting mechanism body includes a reinforced support frame, an adjustment plate is provided on the reinforced support frame, the adjustment plate and the elongated hole fixing plate on the support beam are connected by at least one set of clamping bolts to realize the vertical position adjustment of the two; a rotating wheel is rotatably installed at the bottom of the reinforced support frame through a pin shaft, a steel wire rope is wound on the rotating wheel, and the end of the steel wire rope is connected to a hanging seat.

[0007] Furthermore, two sets of clamping bolts are provided, located at the upper and lower parts of the elongated hole fixing plate and the adjusting plate, respectively.

[0008] Furthermore, the adjusting plate and the elongated hole fixing plate are provided with at least two or more sets, and a connecting plate is provided between two adjacent elongated hole fixing plates.

[0009] Furthermore, the reinforcing support frame is also provided with a tension adjustment bolt; the tension adjustment bolt passes through the connecting plate and the reinforcing support frame, so as to adjust the relative position between the elongated hole fixing plate and the adjusting plate by adjusting the nut on the tension adjustment bolt.

[0010] Furthermore, the wheel is a grooved wheel, and the wire rope is embedded in the groove of the grooved wheel.

[0011] Furthermore, the wire rope is a galvanized wire rope or a stainless steel wire rope.

[0012] The beneficial effects of this utility model are:

[0013] 1. Easy installation: The unit can be quickly positioned and connected to the elongated fixing plate on the support beam via the adjustment plate, without the need for complicated calibration, reducing the installation time of a single hoisting unit by more than 50%.

[0014] 2. Independent fine adjustment: The four hoisting units correspond to the four corners of the rotary screening equipment. Through the cooperation of the long hole fixing plate, the adjusting plate and the tension adjusting bolt, the height of each corner can be adjusted independently with an adjustment accuracy of ±1mm. This ensures the horizontal level of the screen surface and the balanced operation of the transmission block, avoiding abnormal transmission noise or component wear caused by horizontal deviation.

[0015] 3. Flexibility and stability: The flexible connection of the wire rope can buffer the vibration and impact during the operation of the rotary screening equipment. Combined with the control of the resistance of the wheel by the tension adjustment bolt, it can not only ensure the stability of the hoisting, but also avoid stress concentration of the rigid connection.

Detailed Implementation

[0019] To more clearly illustrate the technical solution of this utility model, the accompanying drawings used in the description will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings without creative effort. To facilitate understanding of this utility model, a more detailed description of this utility model will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1 As shown, this utility model is a flexible fine-tuning hoisting mechanism, which is a key component of a symmetrical screening and impurity removal device. This utility model includes four independently set fine-tuning hoisting mechanism bodies 100, which correspond to the four corners of the rotary screening device respectively. Each body has the same structure and is installed at the corresponding position of the support beam 8 above the rotary screening device. Through synergistic action, the rotary screening device can be stably hoisted and precisely adjusted.

[0021] The core load-bearing component of each fine-tuning hoisting mechanism body 100 is the reinforced support frame 6, which possesses high mechanical strength and can withstand the self-weight of the rotary screening equipment and the vibration load during operation. An adjusting plate 2 is located on the upper part of the reinforced support frame 6, and the adjusting plate 2 is parallel and fitted to the elongated hole fixing plate 1 fixed on the support beam 8. The elongated hole fixing plate 1 has vertically oriented elongated holes on its surface and is vertically connected to the support beam 8. The adjusting plate 2 has threaded holes at corresponding positions, and at least one set of clamping bolts 7 passes through the elongated holes of the elongated hole fixing plate 1 and is threadedly connected to the adjusting plate 2, and locked in place by nuts. When it is necessary to adjust the height of the corresponding angle of the rotary screening equipment, simply loosen all the nuts of the clamping bolts 7, loosen or tighten the nuts of the adjusting bolts 3 to raise or lower the fine-tuning hoisting mechanism body, and then lock all the fastening nuts to complete the fixation. This structure eliminates the drilling and calibration steps required for traditional rigid hoisting, enabling rapid vertical adjustment directly through the combination of elongated holes and bolts. The height adjustment time for a single angle is reduced to less than 3 minutes, significantly improving the efficiency of screen surface level calibration and ensuring the balance and stability of the transmission block during operation. Simultaneously, a rotating wheel 5 is rotatably mounted on the bottom of the reinforced support frame 6 via a pin 4. A steel wire rope 9 is wound around the rotating wheel 5, and the end of the steel wire rope 9 is connected to a hanging seat 10. The hanging seat 10 directly connects to the lifting point of the rotary screening equipment, forming a complete force transmission path. The flexible steel wire rope 9 also buffers the vibration of the rotary screening equipment, avoiding stress concentration from rigid connections.

[0022] To enhance the stability of the connection between the adjusting plate 2 and the elongated hole fixing plate 1, two sets of clamping bolts 7 are preferably provided, located at the upper and lower parts of the elongated hole fixing plate 1 and the adjusting plate 2, respectively. The two sets of bolts are symmetrically distributed, which can form a two-point fixation after adjustment, preventing the adjusting plate 2 from tilting or loosening when the rotary screening equipment vibrates, ensuring the positional accuracy after height adjustment, further ensuring the horizontal stability of the screen surface, and reducing wear of transmission components caused by loose connection.

[0023] Considering the size and load-bearing requirements of different rotary screening equipment, at least two or more sets of adjusting plates 2 and elongated hole fixing plates 1 can be set, and connecting plates 11 are welded between adjacent elongated hole fixing plates 1. The cooperation of multiple sets of adjusting plates and elongated hole fixing plates can distribute the lifting load and avoid excessive force on a single connection point; while the connecting plates 11 can connect adjacent elongated hole fixing plates 1 into a whole, enhance the lateral rigidity of the support structure, prevent the elongated hole fixing plates 1 from undergoing lateral deformation under load, and improve the overall load-bearing capacity of the mechanism.

[0024] The reinforcing support frame 6 is also equipped with a tension adjustment bolt 3, which passes vertically through the corresponding through holes of the connecting plate 11 and the reinforcing support frame 6, and is locked at one end with a nut. When it is necessary to fine-tune the relative position between the elongated hole fixing plate 1 and the adjusting plate 2, the clamping bolt 7 should be loosened first, and then the nut at one end of the tension adjustment bolt 3 should be tightened or loosened: when tightened, the distance between the connecting plate 11 and the reinforcing support frame 6 decreases, causing the adjusting plate 2 to move upward relative to the elongated hole fixing plate 1; when loosened, the distance between the connecting plate 11 and the reinforcing support frame 6 increases, causing the adjusting plate 2 to move downward relative to the elongated hole fixing plate 1. This design supplements the accuracy of vertical adjustment, makes the relative position adjustment more flexible, and is especially suitable for correcting small deviations caused by vibration after the installation of rotary screening equipment, ensuring the stability of horizontality during long-term use.

[0025] The swivel wheel 5 is a grooved wheel, the curvature of which matches the diameter of the wire rope 9, and the wire rope 9 is embedded in the groove. The groove structure can effectively limit the lateral displacement of the wire rope 9, prevent the wire rope from falling off during hoisting, and at the same time reduce frictional wear with the wire rope 9, extending the service life of both.

[0026] The wire rope 9 is preferably a galvanized wire rope or a stainless steel wire rope. The galvanized layer or stainless steel material can improve its corrosion resistance and adapt to the humid or dusty environment commonly found in screening equipment. At the same time, this type of wire rope has high flexibility and tensile strength, which can meet the buffering requirements of flexible hoisting, ensure load-bearing safety, and reduce the risk of equipment accidents caused by wire rope breakage.

[0027] In actual use, first, fix the corresponding number of elongated hole fixing plates 1 on the support beam 8 according to the size of the rotary screening equipment, and connect adjacent elongated hole fixing plates 1 through the connecting plate 11; then, initially fix the adjusting plate 2 of the reinforcing support frame 6 to the elongated hole fixing plates 1 through the clamping bolts 7, hang the wire rope 9 and the hanging seat 10 and connect it to the rotary screening equipment; then, use a level to check the levelness of the screen surface, and make a rough adjustment of the vertical height by adjusting the clamping bolts 7 at the corresponding angles, and then fine adjust the relative position by tightening the adjusting bolts 3 until the screen surface is horizontally level; finally, tighten all bolts to complete the installation.

[0028] In summary, this implementation method, through the coordinated design of its components, achieves advantages such as convenient installation, independent fine-tuning at all four corners, structural stability, and strong adaptability. It effectively solves the problems of difficult adjustment, cumbersome installation, and inconvenient maintenance of traditional hoisting mechanisms, and is suitable for the hoisting needs of various screening equipment.
