Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0020] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Example 1 like Figure 1 and Figure 2 As shown in the figure, this embodiment describes a belt break catcher for a belt conveyor. The belt break catcher includes a catcher body, a crossbeam, a reset bracket 1, a hydraulic cylinder 2, a catcher frame, a counterweight 8, and a catcher shoe block 15.

[0023] A crossbeam is mounted on the main body of the catcher, and a reset bracket 1 is mounted on the crossbeam. The cylinder end 21 of the hydraulic cylinder 2 is located on one side of the reset bracket 1, and a pusher is mounted on the telescopic rod end 22 of the hydraulic cylinder 2. The middle position of the catcher frame is hinged to the main body of the catcher; a counterweight 8 is mounted at one end of the catcher frame, and a catcher shoe block 15 is mounted at the other end of the catcher frame; a roller 4 is rotatably mounted on the side of the catcher frame near the catcher shoe block 15. When the conveyor belt 6 of the belt conveyor is running normally, the roller 4 abuts against the bottom of the conveyor belt 6, and the roller 4 can rotate with the conveyor belt 6. At this time, the restriction of the catcher frame by the conveyor belt 6 itself and the weight of the goods on the conveyor belt 6 balance the weight of the counterweight 8. When the conveyor belt 6 of the belt conveyor breaks, the tension of the conveyor belt 6 drops sharply, causing it to slack and slip. At this time, the counterweight 8 drives the capture frame to rotate relative to the capture device body, causing the capture shoe block 15 to abut against the bottom of the conveyor belt 6. The capture shoe block 15 and the crossbeam together squeeze the conveyor belt 6, thereby braking the slipping conveyor belt 6 between the crossbeam and the capture shoe block 15, thus capturing the belt and preventing further accidents. When the broken belt capture device is reset, the telescopic rod end 22 of the hydraulic cylinder 2 extends relative to the cylinder end 21, and the pushing component acts on the end of the capture frame near the capture shoe block 15, pushing the capture shoe block 15 to gradually detach from the conveyor belt 6.

[0024] The crossbeam of the broken belt catcher includes an upper crossbeam 9 and a lower crossbeam, and the catching frame includes an upper catching frame 7 and a lower catching frame. In this embodiment, the reset bracket 1 is disposed on the upper crossbeam 9 to reset the upper catching frame 7, such as... Figure 3 As shown.

[0025] like Figure 3 and Figure 4 As shown, the reset bracket 1 consists of a connector 13, a first side member 11, and a second side member 12. One end of the connector 13 is connected to the first side member 11, and the other end of the connector 13 is connected to the second side member 12. The connector 13, the first side member 11, and the second side member 12 are integrally formed. The reset bracket 1 is fixed to the upper crossbeam 9. Specifically, the connector 13 is located at the top of the upper crossbeam 9, and the first side member 11 and the second side member 12 are located on both sides of the upper crossbeam 9, respectively. The bottom of the cylinder end 21 of the hydraulic cylinder 2 is located on the side of the second side member 12 near the upper crossbeam 9.

[0026] like Figure 5As shown, the second side member 12 is composed of a first fixing member 121, a second fixing member 122, and an extension member 123. The second side member 12 is integrally formed, and its cross-sectional shape is "Z". The first fixing member 121 is located on the side of the upper crossbeam 9 and is arranged vertically. The top end of the first fixing member 121 is connected to the connecting member 13, and the bottom end of the first fixing member 121 is connected to the extension member 123, which is arranged horizontally. The end of the extension member 123 away from the first fixing member 121 is connected to the second fixing member 122, which is arranged vertically. The bottom of the cylinder end 21 of the hydraulic cylinder 2 is located on the side of the second fixing member 122 near the upper crossbeam 9. The extension member 123 extends horizontally outward, and the extension member 123, the second fixing member 122, and the upper crossbeam 9 form a receiving space for installing the hydraulic cylinder 2.

[0027] like Figure 3 As shown, the reset bracket 1 is also provided with a handle 10 to facilitate the installation and removal of the reset bracket 1.

[0028] The broken belt catcher in this embodiment also includes a hydraulic oil pipe 14 and an oil supply unit. One end of the hydraulic oil pipe 14 is connected to the hydraulic cylinder 2, and the other end of the hydraulic oil pipe 14 is connected to the oil supply unit, which supplies oil to the hydraulic cylinder 2 through the hydraulic oil pipe 14.

[0029] In this embodiment, the oil supply unit is set as hydraulic pump station 5. If there is no hydraulic pump station 5 nearby, a manual hydraulic pump 3 or an electric hydraulic pump can be used to provide power to reset the broken belt catcher.

[0030] Taking the installation of the reset bracket 1 on the upper crossbeam 9 as an example, its installation and use process is briefly described as follows: (1) Fix the reset bracket 1 on the upper crossbeam 9 to establish a support point.

[0031] (2) Fix the hydraulic cylinder 2 to the side of the second fixing part 122 of the reset bracket 1 near the upper crossbeam 9.

[0032] (3) When the conveyor belt 6 breaks, the hammer 8 drives the upper capture frame 7 to rotate and carry out the capture action. The capture shoe block 15 firmly clamps the conveyor belt 6 onto the upper crossbeam 9.

[0033] (4) When it is necessary to reset the broken belt catcher, the operator operates the manual hydraulic pump 3 (electric hydraulic pump) or pressurizes the hydraulic cylinder 2 through the hydraulic pump station 5, so that the telescopic rod end 22 of the hydraulic cylinder 2 extends continuously, thereby pushing the upper catcher 7 to rotate, so that the catcher shoe block 15 gradually separates from the conveyor belt 6, and the upper catcher 7 is reset.

[0034] like Figure 1As shown, in order to achieve balanced force on the mechanical structure, two sets of reset brackets 1 are installed on the upper crossbeam 9, arranged separately on the left and right sides. Each reset bracket 1 is equipped with a hydraulic cylinder 2. The two hydraulic cylinders 2 on the left and right sides are pressurized at the same time to ensure balanced force.

[0035] The reset process of the lower capture frame is the same as the reset process of the upper capture frame 7 described above. The reset is still performed in accordance with the above method.

[0036] In this embodiment, the pushing element is set as a roller 23. For example... Figure 6 As shown, the telescopic rod end 22 of the hydraulic cylinder 2 has an installation groove, and a fixed rod 24 is installed in the installation groove. A roller 23 is rotatably mounted on the fixed rod 24, and the roller 23 can rotate around the fixed rod 24. When resetting the broken belt catcher, the manual hydraulic pump 3 (electric hydraulic pump) or the hydraulic pump station 5 is used to pressurize the hydraulic cylinder 2, causing the telescopic rod end 22 of the hydraulic cylinder 2 to extend continuously. The roller 23 rolls and contacts the upper catcher frame 7, thereby pushing the upper catcher frame 7 to rotate, causing the catcher shoe block 15 to gradually detach from the conveyor belt 6, thus realizing the resetting of the upper catcher frame 7.

[0037] Since the upper capture frame 7 does not move horizontally in a straight line during the reset process, but rotates relative to the main body of the capture device, this embodiment provides a roller 23 on the telescopic rod end 22 of the hydraulic cylinder 2. When the roller 23 comes into contact with the upper capture frame 7, the roller 23 can rotate, thereby providing better power to reset the upper capture frame 7.

[0038] The embodiments of this utility model are only used to illustrate the technical solutions of this utility model and are not intended to limit it. For those skilled in the art, it will be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
