Description

Technical Field

[0001] This utility model relates to the field of conveyor braking devices, and in particular to a conveyor braking device. Background Technology

[0002] Mining belt conveyors are core equipment in coal mine production. Driven by friction, they achieve efficient and continuous material transport, playing an irreplaceable role in coal mining, transportation, and storage. However, long-distance underground conveying presents a braking challenge: underground belt conveyors in coal mines commonly operate at large angles, with high capacity and long distances, where the gravitational potential energy of the material is converted into kinetic energy, leading to the risk of conveyor belt loss of control. Therefore, braking devices are needed. However, existing devices have certain drawbacks. For example, Chinese patent CN 216334658U discloses a magnetic adsorption type belt conveyor braking device. This device controls the magnetic force by adjusting the angular velocity of a motor or pneumatic motor to achieve constant deceleration braking, fully automated and requiring no manual assistance. While this device can brake the conveyor, it is pre-fixed to the conveyor, making it inconvenient to install later. Utility Model Content

[0003] This utility model proposes a conveyor braking device to solve the problem of inconvenience in retrofitting existing devices.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a conveyor braking device, comprising a connecting member and a braking member for braking the conveyor. The connecting member includes two symmetrically arranged first clamping plates and second clamping plates. Two base rods are symmetrically fixedly connected to the side of the first clamping plate facing the second clamping plate. The second clamping plate is slidably connected between the two base rods, and a movable nut is screwed onto the base rod. The second clamping plate is located between the nut and the first clamping plate, and a clamping cavity for clamping the conveyor is formed between the second clamping plate and the first clamping plate. The braking member includes a telescopic part and a braking part for braking. The top of the braking part is connected to the telescopic end of the bottom of the telescopic part, and the telescopic part is installed on the side of the first clamping plate away from the second clamping plate.

[0005] Preferably, the free end of the base rod is recessed to form a first connecting hole, a connecting rod is screwed into the first connecting hole, an extension rod is fixedly connected to the end of the connecting rod away from the base rod, and a second connecting hole is formed by recessing the end of the extension rod away from the connecting rod. The outer circumferential surfaces of the base rod and the extension rod are both formed with external threads that match the nut.

[0006] Preferably, a rubber plate is adhered to the opposite side of the first clamping plate and the second clamping plate, the rubber plate is located below the base rod, and the surface of the rubber plate is recessed to form an anti-slip groove.

[0007] Preferably, the telescopic part includes a base frame, which is fixedly connected to the side of the first clamping plate away from the second clamping plate, and a hydraulic cylinder is fixedly connected to the top of the base frame, with a moving rod connected to the telescopic end of the hydraulic cylinder.

[0009] Preferably, a connecting frame is fixedly connected to the top of the base frame, and a through hole is formed in the recess of the connecting frame. A detachable connecting steel cable is installed between the two through holes.

[0010] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0011] (1) By setting up a first clamping plate, a second clamping plate, a base rod and a screw ring, when in use, the device is first placed on the conveyor at the position to be clamped by the first clamping plate and the second clamping plate, then the second clamping plate is connected to the base rod and pulled, and then the screw ring is screwed to the base rod to fix the first clamping plate and the second clamping plate to clamp the conveyor.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-5 As shown, a conveyor braking device includes a connector 1 and a brake 2 for braking the conveyor. The connector 1 includes two symmetrically arranged first clamping plates 11 and second clamping plates 15. Two base rods 12 are symmetrically fixedly connected to the side of the first clamping plate 11 facing the second clamping plate 15. The second clamping plate 15 is slidably connected between the two base rods 12, and a movable nut 19 is screwed onto the base rods 12. The second clamping plate 15 is located between the nut 19 and the first clamping plate 11, and a clamping cavity for clamping the conveyor is formed between the second clamping plate 15 and the first clamping plate 11. The brake 2 includes a telescopic part and a braking part for braking. The top of the braking part is connected to the telescopic end of the bottom of the telescopic part, and the telescopic part is installed on the side of the first clamping plate 11 away from the second clamping plate 15.

[0023] With the above technical solution, before the device needs to be installed, the first clamping plate 11 and the second clamping plate 15 are placed on the conveyor at the position where they need to be clamped. Then, the second clamping plate 15 is connected to the two base rods 12. The second clamping plate 15 is pushed so that it moves along the base rods 12 until the second clamping plate 15 and the first clamping plate 11 clamp the conveyor. Then, the nut 19 is screwed onto the base rods 12 until the nut 19 abuts against the second clamping plate 15, so that the second clamping plate 15 and the first clamping plate 11 abut against the conveyor, thus fixing the second clamping plate 15 and the first clamping plate 11 onto the conveyor. After the first clamping plate 11 and the second clamping plate 15 are fixed, the first clamping plate 11 supports the telescopic part. The telescopic part works so that it drives the braking part to move, so that the braking part abuts against the belt on the conveyor, thereby braking the belt.

[0024] When the device clamps the conveyor, in order to increase the device's range of applications, such as... Figures 1-3 As shown, the free end of the base rod 12 is recessed to form a first connecting hole 13. A connecting rod 17 is screwed into the first connecting hole 13. An extension rod 16 is fixedly connected to the end of the connecting rod 17 away from the base rod 12. The end of the extension rod 16 away from the connecting rod 17 is recessed to form a second connecting hole 18. The outer circumferential surfaces of the base rod 12 and the extension rod 16 are both formed with external threads that match the nut 19.

[0025] In this embodiment, before fixing the first clamping plate 11 and the second clamping plate 15, a corresponding number of extension rods 16 are taken and connected to the second connecting hole 18 by connecting rod 17, so that several extension rods 16 are connected end to end. Then, the adjusted extension rods 16 are connected to the first connecting hole 13 on the base rod 12 by connecting rod 17, thereby adjusting the adjustment range of the second clamping plate 15. Then, the first clamping plate 11 and the second clamping plate 15 are respectively placed on both sides of the conveyor where the fixed position is required. Pull the second clamping plate 15 so that the second clamping plate 15 slides along the extension rod 16 and the base rod 12 until the second clamping plate 15 and the first clamping plate 11 clamp the conveyor, thereby further increasing the application range of the device.

[0026] When the first clamping plate 11 and the second clamping plate 15 clamp the conveyor, in order to improve the tightness of the device during fixation, such as Figures 1-3 As shown, rubber plates 14 are glued to the opposite sides of the first clamping plate 11 and the second clamping plate 15. The rubber plates 14 are located below the base rod 12, and the surface of the rubber plates 14 is recessed to form anti-slip grooves.

[0027] In this embodiment, when the first clamping plate 11 and the second clamping plate 15 clamp the conveyor, the rubber plate 14 and the anti-slip groove cooperate to make the first clamping plate 11 and the second clamping plate 15 clamp the conveyor more securely, thereby improving the tightness of the device during installation.

[0028] Specifically, in one embodiment, regarding the aforementioned telescopic portion, as... Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the telescopic part includes a base frame 21, which is fixedly connected to the side of the first clamping plate 11 away from the second clamping plate 15, and a hydraulic cylinder 22 is fixedly connected to the top of the base frame 21. The telescopic end of the hydraulic cylinder 22 is connected to a moving rod 23.

[0029] In this embodiment, after the first clamping plate 11 and the second clamping plate 15 clamp the conveyor, the first clamping plate 11 supports the base frame 21, and the base frame 21 supports the hydraulic cylinder 22. The hydraulic cylinder 22 works, thereby driving the moving rod 23 to move, which in turn drives the braking part to move, thereby pressing the conveyor belt on the conveyor and braking the conveyor.

[0030] Furthermore, in this utility model, regarding the aforementioned braking part, as follows: Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the braking part includes a pressure plate 24, the top of which is fixedly connected to the top of the moving rod 23, and the bottom of the pressure plate 24 is bonded with an anti-slip protrusion 25.

[0031] In this embodiment, when the moving rod 23 moves, the moving rod 23 will synchronously drive the pressure plate 24 to move, and the pressure plate 24 will press the conveyor belt, thereby braking the conveyor. In addition, the anti-slip protrusion 25 will help make the pressure plate 24 more stable when braking.

[0032] In order to connect multiple base frames 21, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a connecting frame 26 is fixedly connected to the top of the base frame 21. A through hole 28 is formed in the indentation of the connecting frame 26. A detachable connecting steel cable 3 is installed between the two through holes 28. A movable limiting rod 27 is screwed onto the top of the connecting frame 26. The free end of the limiting rod 27 extends into the through hole 28 and abuts against the connecting steel cable 3.

[0033] In this embodiment, after the first clamping plate 11 and the second clamping plate 15 clamp and fix the conveyor, the first clamping plate 11 supports the base frame 21, and the base frame 21 supports the connecting frame 26. Then, the connecting steel cable 3 is inserted into the through hole 28 between the two connecting frames 26, and then the limiting rod 27 is screwed to the connecting frame 26, so that the free end of the limiting rod 27 extends into the through hole 28 inside the connecting frame 26, thereby fixing the connecting steel cable 3 to the connecting frame 26, so that the device brakes the conveyor more smoothly.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
