Description

Technical Field

[0001] This utility model relates to the field of conveyor belt clamping and loosening, and more specifically, to an automatic conveyor belt clamping and loosening device. Background Technology

[0002] In industries such as coal and non-coal mining, approximately 30 billion tons of loose materials (coal, iron, and non-ferrous metal ores, etc.) are transported annually through a series of multiple belt conveyors. Many of these transport operations involve long distances, high speeds, and heavy-duty inclined transport.

[0003] A belt conveyor with a certain tension not only carries all the materials but also interacts with transmission components such as rollers and idlers, generating periodic alternating stresses and strains. Improper start-stop control, or sudden power outages or emergency braking, can easily lead to damage to the belt, rollers, and bearings under the influence of impact loads and gravitational potential energy, potentially resulting in serious accidents such as belt breakage. Therefore, regular maintenance and belt replacement of belt conveyors are of paramount importance.

[0004] Whether it's regular maintenance of belt conveyors or periodic belt replacement, belt loosening is necessary to facilitate subsequent maintenance work. Currently, the most common method for loosening belts is for workers to secure the belt with multiple clamps, requiring the assistance of a winch. Firstly, manually securing the belt with multiple clamps not only fails to ensure simultaneous clamping of the upper and lower belts but also consumes a significant amount of unnecessary manpower and time. Secondly, each belt loosening and securing session is time-consuming, and the manual clamping method, requiring both winch and manual operation, is susceptible to safety issues due to numerous external factors. Finally, manual clamping makes it difficult to ensure even distribution of clamping force on the belt during clamping, easily leading to belt slippage and potentially serious accidents.

[0005] In existing technologies, the clamping and loosening operations of conveyor belts often have some shortcomings. Traditional conveyor belt clamping devices are usually operated manually or mechanically, which is not only cumbersome but also inefficient, requiring a lot of manpower and time. In addition, this operation method makes it difficult to precisely control the clamping force and position, which can easily lead to uneven stress on the conveyor belt, affecting its service life and operational stability.

[0006] Traditional belt unloading devices also have some problems. Because the belt unloading process is not flexible enough and cannot respond to the operating needs of the conveyor belt in a timely and accurate manner, it may cause the conveyor belt to jam or slip during operation, affecting the normal operation of production.

[0007] Furthermore, existing conveyor belt clamping devices often exhibit poor versatility when adapting to conveyor belts of different specifications. Different clamping devices are required for different sizes and models of conveyor belts, increasing production costs and operational complexity.

[0008] Furthermore, the structural stability of traditional devices needs improvement. During long-term operation, problems such as structural loosening and deformation can easily occur, affecting the normal use and safety of the device. Therefore, we have made improvements and proposed an automatic conveyor belt clamping and loosening device. Utility Model Content

[0031] 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.

[0032] 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.

[0033] Example 1: Please refer to Figures 1-5 An automatic conveyor belt clamping and loosening device includes a top beam 1, vertical guide beams 2 on both sides of the top beam 1, a clamping and loosening power mechanism 6 on the top beam 1, the clamping and loosening power mechanism 6 being connected to a lower pressure beam 3, a lower clamping beam 4 below the lower pressure beam 3, and a support beam 5 below the lower clamping beam 4. The clamping and loosening power mechanism 6 is equipped with a first hydraulic cylinder 61, a first hydraulic telescopic rod 62 within the first hydraulic cylinder 61, and a first hinge 63 at the end of the first hydraulic telescopic rod 62. The clamping and loosening power mechanism 6 also includes a second hydraulic cylinder 64, a second hydraulic telescopic rod 65 within the second hydraulic cylinder 64, and a second hinge 66 at the end of the second hydraulic telescopic rod 65.

[0034] Both the first hinge 63 and the second hinge 66 are connected to the lower pressure beam 3. The lower clamping beam 4 is equipped with a snap-fit ​​groove assembly 7, of which two sets are provided. The snap-fit ​​groove assembly 7 has a snap-fit ​​U-shaped groove 71, which engages with a snap-fit ​​rod 72. A snap-fit ​​adjusting nut 73 is provided on the snap-fit ​​rod 72. A gap is provided between the lower clamping beam 4 and the support beam 5, through which the conveyor belt passes. The top beam 1 and the vertical guide beam 2 are connected by fastening bolts 8.

[0035] The working principle of the automatic conveyor belt clamping and loosening device is as follows: When a clamping operation is required on the conveyor belt, the first hydraulic cylinder 61 and the second hydraulic cylinder 64 in the clamping and loosening power mechanism 6 begin to work. The first hydraulic telescopic rod 62 in the first hydraulic cylinder 61 extends and pushes the lower pressure beam 3 through the first hinge 63 at its end; simultaneously, the second hydraulic telescopic rod 65 in the second hydraulic cylinder 64 also extends and pushes the lower pressure beam 3 through the second hinge 66 at its end. Under the combined action of the first hydraulic telescopic rod 62 and the second hydraulic telescopic rod 65, the lower pressure beam 3 moves downward.

[0036] The lower clamping beam 4 below the lower pressure beam 3 moves downward accordingly, and the buckle U-shaped groove 71 in the buckle groove assembly 7 on the lower clamping beam 4 engages with the buckle rod 72. By adjusting the buckle adjusting nut 73 on the buckle rod 72, the buckle rod 72 can be fixed in the buckle U-shaped groove 71, thereby achieving the clamping of the conveyor belt.

[0037] When it is necessary to loosen the conveyor belt, the hydraulic telescopic rods of the first hydraulic cylinder 61 and the second hydraulic cylinder 64 retract, causing the lower pressure beam 3 to move upward, and the lower clamping beam 4 to rise accordingly, releasing the clamping of the conveyor belt and allowing the conveyor belt to operate normally in the gap.

[0038] The entire device ensures the vertical movement direction of the lower pressure beam 3 and the lower clamping beam 4 through the vertical guide beams 2 on both sides of the top beam 1. The top beam 1 and the vertical guide beams 2 are connected by fastening bolts 8 to ensure the stability of the entire structure. The conveyor belt passes through the gap between the lower clamping beam 4 and the support beam 5 to achieve the clamping or loosening of the belt.

[0039] The working process of the automatic conveyor belt clamping and loosening device is as follows:

[0040] 1. Initial state: The conveyor belt passes through the gap between the lower clamping beam 4 and the support beam 5 and is in normal operation. At this time, the hydraulic telescopic rods of the first hydraulic cylinder 61 and the second hydraulic cylinder 64 of the clamping and loosening power mechanism 6 are in the retracted state, and the lower pressure beam 3 and the lower clamping beam 4 are located above.

[0041] 2. Carrying operation:

[0042] When it is necessary to clamp the conveyor belt, activate the clamping and loosening power mechanism 6.

[0043] The first hydraulic telescopic rod 62 in the first hydraulic cylinder 61 extends out and pushes the lower pressure beam 3 through the first hinge 63 at the end; at the same time, the second hydraulic telescopic rod 65 in the second hydraulic cylinder 64 also extends out and pushes the lower pressure beam 3 through the second hinge 66 at the end.

[0044] The lower pressure beam 3 moves downward under the combined action of the first hydraulic telescopic rod 62 and the second hydraulic telescopic rod 65, causing the lower clamping beam 4 below to move downward together.

[0045] The buckle U-shaped groove 71 in the buckle groove assembly 7 on the lower clamping beam 4 cooperates with the buckle rod 72. By adjusting the buckle adjusting nut 73 on the buckle rod 72, the buckle rod 72 is fixed in the buckle U-shaped groove 71, thereby realizing the clamping of the conveyor belt.

[0046] 3. Loosening the belt:

[0047] When it is necessary to loosen the conveyor belt, the hydraulic telescopic rods of the first hydraulic cylinder 61 and the second hydraulic cylinder 64 of the belt loosening power mechanism 6 retract.

[0048] The first hydraulic telescopic rod 62 and the second hydraulic telescopic rod 65 drive the lower pressure beam 3 to move upward, and the lower clamping beam 4 also rises accordingly.

[0049] The latching rod 72 on the lower clamping beam 4 separates from the latching U-shaped groove 71, releasing the clamping of the conveyor belt and allowing the conveyor belt to operate normally in the gap.

[0050] Throughout the entire operation, the vertical guide beams 2 on both sides of the top beam 1 ensure the vertical movement direction of the lower pressure beam 3 and the lower clamping beam 4. The top beam 1 and the vertical guide beams 2 are connected by fastening bolts 8 to ensure the structural stability of the entire device.

[0051] 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 equivalent 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.
