Description

Technical Field

[0001] This utility model relates to the field of coal and non-coal mine transportation, and more specifically, to a convenient electro-hydraulic linkage device for switching clamping and loosening. Background Technology

[0002] In the coal and non-coal mining industries, the transportation of loose materials (such as coal, iron and non-ferrous metal ores) typically relies on a series of multiple belt conveyors. Under long-distance, high-speed, heavy-load, and inclined transportation conditions, the belts with a certain tension, while carrying the material, also interact with the rollers and idler drive components, generating periodic alternating stresses and strains.

[0003] However, existing belt conveyors have many problems during operation. First, during start-up and shutdown control, sudden power outages, or emergency braking, the belt is easily damaged due to impact loads and gravitational potential energy, potentially leading to belt breakage and other serious accidents. Second, during regular maintenance and belt replacement, both the upper and lower belts need to be clamped simultaneously. The current method of manually securing the belts with multiple clamps not only fails to ensure simultaneous clamping but also consumes significant manpower and time. This method is inefficient, increases production costs, and fails to guarantee effective belt clamping, posing safety hazards. Furthermore, traditional clamping methods are complex to operate, require highly skilled operators, and are prone to errors, further impacting normal production. Therefore, we propose a convenient electro-hydraulic linkage device for switching between clamping and loosening. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0028] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely illustrates some embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, in the absence of conflict, the embodiments and features and technical solutions in the embodiments of this utility model can be combined with each other. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Example 1: Please refer to Figures 1-5 A convenient switching clamping and loosening electro-hydraulic linkage device includes a main frame 1, a crossbeam 2 on the main frame 1, a conveyor belt trough 3 below the crossbeam 2, an L-shaped mounting frame 4 on the main frame 1, a hinged connecting frame 5 below the L-shaped mounting frame 4, a lifting cylinder 6 on the hinged connecting frame 5, a telescopic rod 7 inside the lifting cylinder 6, and the lifting cylinder 6 being connected to a linkage component 8.

[0030] The linkage component 8 is provided with a linkage chain 81, which is sleeved on a fixed pulley 82. The fixed pulley 82 is mounted on a pulley frame 821, and the pulley frame 821 is connected to the upper end of the L-shaped mounting bracket 4.

[0031] A hanging ring 61 is provided above the lifting cylinder 6, and the hanging ring 61 is connected to one end of the linkage chain 81. Two L-shaped mounting brackets 4 are provided and are symmetrical to each other. The telescopic rod 7 is connected to the clamping base 9, and an upper adhesive tape 91 is provided above the clamping base 9. A lower adhesive tape 101 is provided above the upper adhesive tape 91 and is located below the pressure belt fixing beam 10.

[0032] The main frame 1 is connected to the conveyor belt support frame 11. The lifting cylinder 6 is connected to the hydraulic control check valve, which is individually connected to the plunger cylinder and the piston cylinder.

[0033] The working principle of the convenient clamping and loosening electro-hydraulic linkage equipment is as follows: When clamping of the conveyor belt is required, the hydraulic check valve controls the liquid to enter the plunger cylinder and piston cylinder, thereby pushing the telescopic rod 7 in the lifting cylinder 6 to extend downward. The telescopic rod 7 is connected to the clamping base 9, and as the telescopic rod 7 extends, the clamping base 9 moves upward.

[0034] The upper tape 91 above the clamping base 9 and the lower tape 101 below the pressure fixing beam 10 cooperate with each other. When the clamping base 9 moves upward, the upper tape 91 and the lower tape 101 gradually approach and clamp the conveyor belt, thus achieving the clamping function.

[0035] During the operation of the lifting cylinder 6, the lifting cylinder 6 and the linkage assembly 8 cooperate with each other. The hanging ring 61 above the lifting cylinder 6 is connected to one end of the linkage chain 81. The linkage chain 81 is fitted onto the fixed pulley 82, which is mounted on the pulley frame 821. The pulley frame 821 is connected to the upper end of the L-shaped mounting bracket 4. When the telescopic rod 7 of the lifting cylinder 6 extends, the hanging ring 61 pulls the linkage chain 81, causing the linkage chain 81 to move on the fixed pulley 82, thus providing balance and assistance.

[0036] When the conveyor belt needs to be released, the hydraulic check valve controls the liquid backflow, reducing the pressure in the plunger cylinder and piston cylinder. The telescopic rod 7 in the lifting cylinder 6 retracts under the action of gravity or other external forces. As the telescopic rod 7 retracts, the clamping base 9 moves downward, reducing the clamping force between the upper belt 91 and the lower belt 101, thereby releasing the conveyor belt.

[0037] The conveyor belt trough 3 below the crossbeam 2 is used to transport the conveyor belt. The main frame 1 is connected to the conveyor belt support frame 11 to provide support and stability for the entire equipment.

[0038] In summary, this convenient electro-hydraulic linkage equipment for switching clamping and loosening uses a hydraulic check valve to control the extension and retraction of the lifting cylinder 6, thereby achieving the clamping and loosening of the conveyor belt by the upper belt 91 and the lower belt 101. At the same time, the linkage component 8 plays an auxiliary and balancing role, improving the working efficiency and stability of the equipment.

[0039] In coal and non-coal mining, is it necessary to perform regular maintenance on belt conveyors or periodic replacement of the belts? This convenient electro-hydraulic linkage device for switching clamping and loosening is employed. The operator sends a clamping signal through the control system. Upon receiving the signal, the hydraulic check valve controls the flow of fluid into the plunger and piston cylinders, pushing the telescopic rod 7 within the lifting cylinder 6 to extend. The telescopic rod 7 moves the clamping base 9 upwards, causing the upper belt 91 above the clamping base 9 to gradually approach the lower belt 101 below the pressure fixing beam 10. As the upper belt 91 and lower belt 101 contact and press together, the components are securely clamped.

[0040] During the operation of the lifting cylinder 6, the hanging ring 61 above the lifting cylinder 6 pulls the linkage chain 81, and the linkage chain 81 moves smoothly on the fixed pulley 82 to ensure the stable operation of the lifting cylinder 6.

[0041] Once the maintenance is complete, the control system sends a release signal, the hydraulic check valve controls the liquid return, the telescopic rod 7 inside the lifting cylinder 6 retracts, the clamping base 9 descends, the clamping force between the upper tape 91 and the lower tape 101 decreases, and the parts are released.

[0042] The specific workflow of the convenient switching clamping and loosening electro-hydraulic linkage equipment:

[0043] 1. Initial state: The equipment is in a non-working state, the telescopic rod 7 of the lifting cylinder 6 is in the retracted state, the upper conveyor belt 91 and the lower conveyor belt 101 are in a separated state, and the conveyor belt is not clamped.

[0044] 2. Clamping the conveyor belt: After receiving the clamping signal, the hydraulic check valve controls the liquid to enter the plunger cylinder and piston cylinder. The pressure of the liquid pushes the telescopic rod 7 inside the lifting cylinder 6 to extend.

[0045] The telescopic rod 7 drives the clamping base 9 to move upward. The upper conveyor belt 91 above the clamping base 9 rises accordingly, gradually approaching the lower conveyor belt 101 below the pressure beam 10. When the upper conveyor belt 91 and the lower conveyor belt 101 contact and press against each other, the conveyor belt is clamped. Simultaneously with the operation of the lifting cylinder 6, the hanging ring 61 above the lifting cylinder 6 pulls the linkage chain 81. The linkage chain 81 moves on the fixed pulley 82, and the pulley frame 821 and the L-shaped mounting bracket 4 provide support and stability, ensuring the smooth operation of the lifting cylinder 6.

[0046] 4. Release the conveyor belt: When the conveyor belt reaches the designated position and needs to be released, the hydraulic check valve receives the release signal. The hydraulic check valve controls the liquid backflow, reducing the pressure in the plunger cylinder and piston cylinder.

[0047] The telescopic rod 7 inside the lifting cylinder 6 retracts under the action of gravity or other external forces. The telescopic rod 7 drives the clamping base 9 to move downward. The upper conveyor belt 91 above the clamping base 9 then descends, reducing the clamping force between it and the lower conveyor belt 101. The conveyor belt is no longer clamped, achieving the release operation.

[0048] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
