Description

Technical Field

[0001] This utility model relates to the field of tape breakage capture device technology, specifically a full-section tape breakage capture device. Background Technology

[0002] Belt conveyors are commonly used conveying equipment in industries such as mining, metallurgy, ports, and power, typically for the continuous transport of bulk materials. During operation, prolonged use, overloading, or unexpected factors (such as roller jamming or material impact) can cause the conveyor belt to break. If a broken conveyor belt is not promptly and effectively secured, the broken pieces may be thrown out, posing a safety threat to surrounding equipment and personnel.

[0003] Currently, most conveyor belt breakage protection devices on the market rely on electronic control systems for detection and braking, which suffers from problems such as response delay, complex structure, and high maintenance costs. In addition, some mechanical capture devices use a single-sided or unidirectional capture method, which cannot effectively fix both ends of the conveyor belt, resulting in unstable capture and the risk of slippage. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a full-section conveyor belt breakage catcher that is simple in structure, responds quickly, catches reliably, and is easy to maintain, thereby improving safety and equipment operational stability in the event of conveyor belt breakage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A full-section belt breakage catcher is installed on the frame of a belt conveyor, on which a conveyor belt is mounted. It includes an upper catching hammer close to the lower part of the conveyor belt's load-bearing section, a lower catching hammer close to the upper part of the conveyor belt's return section, a counterweight hammer mounted on the upper catching hammer, and a locking assembly. Two locking assemblies are configured, installed at corresponding positions on the upper and lower catching hammers. Each locking assembly includes a buffer anti-slip device and a catching block. The catching block is fixed to the frame. The buffer anti-slip device includes a base, a vertical frame, a tilting plate, a friction pad, and a pressure block. The bases of the two buffer anti-slip devices are respectively fixed to the upper and lower catching hammers. The vertical frame is fixed to the base. The pressure block is fixed to the base on the side near the catching block. The tilting plate is rotatably mounted on the vertical frame. The friction pad is fixed to the tilting plate on the side away from the base. A first limiting strip is fixedly provided on the base. The first limiting strip is located on the side of the vertical frame away from the pressure block, and one end of the first limiting strip abuts against the tilting plate.

[0007] Preferably, it further includes a second limiting strip; the second limiting strip is fixed on the base; the second limiting strip is located between the pressure block and the upright; a rotation interval is provided between the second limiting strip and the flip plate.

[0008] Preferably, the pressing block is provided with a first clamping inclined surface; the capturing block is provided with a second clamping inclined surface that cooperates with the first clamping inclined surface.

[0009] Preferably, the upper grab hammer is provided with a first shaft, which is rotatably mounted on the frame; a counterweight is fixed on the first shaft; the upper grab hammer is provided with an upper auxiliary wheel that rolls in contact with the lower part of the conveyor belt's carrying section; the lower grab hammer is provided with a second shaft, which is rotatably mounted on the frame; and the lower grab hammer is provided with a lower auxiliary wheel that contacts the upper part of the conveyor belt's return section.

[0010] Preferably, it further includes a linkage plate; the linkage plate is fixed on the second shaft; the upper end face of the linkage plate abuts against the lower end face of the upper grabbing hammer at the end away from the first shaft.

[0011] Preferably, it further includes a first pin and a second pin; the upper capture hammer is provided with a first insertion hole, and the lower capture hammer is provided with a second insertion hole; the first pin is inserted and installed on the frame, with its end inserted into the first insertion hole; the second pin is inserted and installed on the frame, with its end inserted into the second insertion hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Rapid Response Capture: This device uses a counterweight to drive the upper capture hammer to rotate, and provides additional acceleration force through the contact between the friction pad and the conveyor belt, so that the capture action is completed quickly, avoiding accidental slippage after the conveyor belt breaks, and improving safety.

[0014] Buffer protection design: The tilting plate's deflectable design on the stand provides a buffering effect during the capture process, reducing the impact on the equipment and extending the device's service life.

[0015] Two-way synchronous capture: The linkage mechanism of the upper and lower capture hammers ensures that they rotate synchronously, effectively fixing both ends of the conveyor belt, preventing the broken conveyor belt from being thrown out or slipping, and improving the reliability of the equipment.

[0016] Enhanced friction and reduced slippage: With the addition of a buffer anti-slip device, the friction pad makes full contact with the conveyor belt during the capture process, and the clamping slope design of the pressure block and the capture block ensures that the conveyor belt is reliably clamped, preventing slippage and improving the capture effect.

[0017] High maintainability: The design of the first and second pins allows the capture device to be fixed during maintenance and replacement of the conveyor belt, preventing parts from accidentally flipping due to gravity, thus improving safety and ease of maintenance. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figures 1 to 5As shown, a full-section belt breakage catcher is installed on the frame 1 of a belt conveyor, on which a conveyor belt is mounted; it is used to catch belt breakage when the conveyor belt breaks; it includes an upper catching hammer 3 close to the lower part of the conveyor belt's load-bearing section, a lower catching hammer 6 close to the upper part of the conveyor belt's return section, and a counterweight hammer 2 installed on the upper catching hammer 3, which provides the power for the upper catching hammer 3 to rotate; it also includes a locking assembly to increase the friction between the catcher and the conveyor belt when catching the belt, reducing slippage; there are two locking assemblies, installed at corresponding positions on the upper catching hammer 3 and the lower catching hammer 6; the locking assembly includes a buffer anti-slip device 5 and a catching block 4; the catching block 4 is fixed on the frame 1; specifically, one catching block 4 is positioned above the upper capture hammer 3, and another capture block 4 is positioned below the lower capture hammer 6; the buffer anti-slip device 5 includes a base 15, a stand 16, a flip plate 19, a friction pad 20, and a pressure block 18; the bases 15 of the two buffer anti-slip devices 5 are respectively fixed on the upper capture hammer 3 and the lower capture hammer 6; the stand 16 is fixed on the base 15; the pressure block 18 is fixed on the base 15 on the side near the capture block 4; the flip plate 19 is rotatably mounted on the stand 16; the friction pad 20 is fixed on the side of the flip plate 19 away from the base 15; a first limiting strip 14 is fixedly provided on the base 15; the first limiting strip 14 is located on the side of the stand 16 away from the pressure block 18; one end of the first limiting strip 14 abuts against the flip plate 19. When the conveyor belt breaks, the counterweight causes the upper grab hammer 3 to flip, causing the buffer anti-slip device 5 of the upper grab hammer 3 to move towards the upper grab block 4. During the flipping process of the upper grab hammer 3, the flipping plate 19 of the buffer anti-slip device 5 first contacts the conveyor belt, and the friction pad 20 rubs against the conveyor belt. The friction pulls the upper grab hammer 3 to accelerate its flipping until the pressure block 18 abuts against the upper grab block 4. Since the flipping plate 19 is hinged to the upright 16, when the friction pad 20 just contacts the fast-moving conveyor belt, the conveyor belt will give the flipping plate 19 a moving pulling force, causing the flipping plate 19 to deflect on the upright 16. The deflection acceleration process of the flipping plate 19 can provide a buffer process for the accelerated movement of the upper grab hammer 3, so that the buffer anti-slip device 5 can drive the upper grab hammer 3 to flip onto the grab block 4 in the shortest time and fix the conveyor belt. When the upper grabbing hammer 3 flips, the first limiting strip 14 is used to limit the flipping plate 19 to prevent it from rotating in the opposite direction due to inertia. The lower grabbing hammer 6 flips downward naturally under the action of gravity, and the working principle of grabbing is the same as that of the upper grabbing hammer 3.

[0027] Furthermore, it also includes a second limiting strip 17; the second limiting strip 17 is fixed on the base 15; the second limiting strip 17 is located between the pressure block 18 and the upright frame 16; a rotation interval is provided between the second limiting strip 17 and the tilting plate 19. The setting of the rotation interval can ensure that the tilting plate 19 rotates within a certain angle range, so that the friction pad 20 of the tilting plate 19 is always in contact with the conveyor belt.

[0028] Furthermore, the pressure block 18 is provided with a first clamping ramp; the grabbing block 4 is provided with a second clamping ramp that cooperates with the first clamping ramp. The conveyor belt is clamped between the first clamping ramp of the pressure block 18 and the second clamping ramp of the grabbing block 4.

[0029] Furthermore, the upper grab hammer 3 is provided with a first shaft 7, which is rotatably mounted on the frame 1; the counterweight hammer 2 is fixed on the first shaft 7; the upper grab hammer 3 is provided with an upper auxiliary wheel 11 that rolls in contact with the lower part of the conveyor belt's carrying section; the lower grab hammer 6 is provided with a second shaft 8, which is rotatably mounted on the frame 1; the lower grab hammer 6 is provided with a lower auxiliary wheel 12 that contacts the upper part of the conveyor belt's return section.

[0030] Furthermore, it also includes a linkage plate 13; the linkage plate 13 is fixed on the second shaft 8; the upper end face of the linkage plate 13 abuts against the lower end face of the upper grab hammer 3 away from the first shaft 7. When the conveyor belt breaks, the upper grab hammer 3 flips over, causing the upper grab hammer 3 to disengage from the linkage plate 13, and the lower grab hammer 6 naturally flips downward under the action of gravity.

[0031] Furthermore, it also includes a first pin 10 and a second pin 9; the upper grab hammer 3 is provided with a first insertion hole, and the lower grab hammer 6 is provided with a second insertion hole; the first pin 10 is inserted and installed on the frame 1, with its end inserted into the first insertion hole; the second pin 9 is inserted and installed on the frame 1, with its end inserted into the second insertion hole. When the first pin 10 is inserted into the first insertion hole and the second pin 9 is inserted into the second insertion hole, the upper grab hammer 3 presses on the linkage plate 13, and neither the upper grab hammer 3 nor the lower grab hammer 6 will deflect due to gravity, making it convenient to change the conveyor belt.

[0032] Working principle

[0033] When the belt conveyor is running normally, both the upper grab hammer 3 and the lower grab hammer 6 are in a stable state. The upper auxiliary wheel 11 of the upper grab hammer 3 is in rolling contact with the lower part of the conveyor belt carrying section, and the lower auxiliary wheel 12 of the lower grab hammer 6 is in rolling contact with the upper part of the conveyor belt return section, ensuring that the device is in a standby state.

[0034] When the conveyor belt breaks, the counterweight 2, under the action of gravity, causes the upper grabbing hammer 3 to quickly flip, causing its buffer anti-slip device 5 to move towards the upper grabbing block 4. During the flipping process, the flipping plate 19 of the buffer anti-slip device 5 first contacts the conveyor belt, and the friction pad 20 rubs against the surface of the conveyor belt, thereby generating frictional force that pulls the upper grabbing hammer 3 to accelerate its flipping until the pressure block 18 abuts against the upper grabbing block 4. At this time, since the flipping plate 19 is hinged to the upright 16, when the friction pad 20 contacts the rapidly moving conveyor belt, the conveyor belt applies a pulling force to the flipping plate 19, causing it to deflect. This deflection process provides a buffering effect for the upper grabbing hammer 3, enabling it to grab and fix the conveyor belt in the shortest possible time. At the same time, the first limiting strip 14 limits the flipping plate 19 to prevent it from rotating in the opposite direction due to inertia.

[0035] The lower grab hammer 6 rotates naturally under gravity, and its grabbing principle is the same as that of the upper grab hammer 3. When the upper grab hammer 3 rotates, the linkage plate 13 loses its supporting function, causing the lower grab hammer 6 to rotate synchronously and complete the grabbing, so that both ends of the broken conveyor belt can be effectively fixed.

[0036] In addition, by setting the first pin 10 and the second pin 9, the device prevents the upper grab hammer 3 and the lower grab hammer 6 from deflecting due to gravity when the conveyor belt is being repaired or replaced, thus improving safety and ease of operation.
