[0036] A traveling belt conveyor is a type of belt conveyor equipment. It consists of a traveling unloading trolley positioned along the length of the conveyor belt. This trolley ejects material from different positions along the belt's length. Therefore, the traveling unloading trolley needs to stop at different points on the track to unload material. To achieve these stops, the drive wheels are braked. However, there is a possibility of slippage after the traveling unloading trolley stops. Furthermore, given the limited space within the track, existing rail clamps are difficult to apply to traveling unloading trolleys.

[0037] Therefore, this application provides a device to prevent slippage of a traveling belt conveyor, which can prevent the unloading car from slipping and is also applicable to situations where the inner side of the traveling track is restricted.

[0038] Reference Figures 1 to 6 An embodiment of the present application provides a device for preventing slippage of a traveling belt conveyor, comprising:

[0039] Walking track 100;

[0040] The unloading vehicle 200 is supported on the travel rail 100 by rollers 202;

[0041] The friction mechanism is located on one or both sides of the unloading vehicle 200. The friction mechanism includes a friction part 301, which has a first state and a second state. In the first state, the friction part 301 is located on the outside of the travel track 100. In the second state, the friction part 301 abuts against the outer wall of the travel track 100.

[0042] The specific location of the friction mechanism can be set according to the actual situation, and it can be selectively set on the left, right or both sides of the unloading vehicle 200. When set on the left or right sides, the friction mechanisms on both sides can be symmetrically distributed or staggered along the travel direction of the unloading vehicle 200.

[0043] It is understood that in this embodiment of the anti-slip device for the traveling conveyor belt, the unloading car 200 is provided with a friction part 301 on the outer side of the traveling track 100. The friction part 301 clamps the unloading car 200 from the outer side of the traveling track 100. During normal travel, the friction part 301 is adjusted to a first state, moving it away from the traveling track 100. When stopped, the friction part 301 is adjusted to a second state, abutting against the outer wall of the traveling track 100, thereby preventing the unloading car 200 from moving relative to the traveling track 100 and achieving the function of preventing slippage. Furthermore, since the friction part 301 is located on the outer side of the traveling track 100, it will not be obstructed even when the space inside the traveling track 100 is limited.

[0044] Reference Figures 1 to 4 In some embodiments of this application, the friction part 301 is rotatably connected to the unloading vehicle 200, and the friction part 301 switches between a first state and a second state by rotating.

[0045] With the structural configuration of this embodiment, during the rotation of the friction part 301, only the part that abuts against the travel track 100 will open outward, rather than the whole part moving outward. This helps to reduce space occupation and avoids interference with other external structures or equipment.

[0046] Furthermore, the method of controlling the rotation of the friction part 301 has lower requirements for the drive, which is beneficial for controlling production costs.

[0047] Reference Figures 1 to 4 In some embodiments of this application, the friction mechanism further includes:

[0048] Link 304 is movably and adjustablely mounted on the unloading vehicle 200 along the width direction of the unloading vehicle 200, and is connected to the friction part 301;

[0049] The drive unit 303 is disposed on the unloading vehicle 200 and is connected to the connecting rod 304. The drive unit 303 can drive the friction unit 301 to rotate through the connecting rod 304.

[0050] During operation, the drive unit 303 moves left and right along the width direction of the unloading vehicle 200 by controlling the connecting rod 304, thereby driving the friction unit 301 to rotate.

[0051] Specifically, in some embodiments of this application, the drive unit 303 is a motor lead screw structure, and the connecting rod 304 is threadedly connected to the lead screw of the drive unit 303. The drive unit 303 controls the switching of the friction unit 301 between a first state and a second state by controlling the forward and reverse rotation of the lead screw. Using a lead screw drive method has a self-locking effect; for example, when the friction unit 301 is in the first state, the stability of the first state can be automatically ensured without the need for the drive unit 303 to provide continuous force. When in the second state, the reaction force from the traveling track 100 on the friction unit 301 is also unlikely to drive the lead screw to rotate, thus improving the stability of the state and reducing the requirements for the motor.

[0052] Reference Figure 4 In some embodiments of this application, friction mechanisms are symmetrically provided with friction parts 301 and connecting rods 304 on both sides of the unloading vehicle 200, the lead screw is provided with two sections of threads with opposite directions of rotation, and the connecting rods 304 on both sides are respectively connected to one section of thread.

[0053] It is understood that this embodiment uses one drive unit 303 to drive two friction units 301, which simplifies the structural composition. The drive unit 303 uses the forward and reverse threads of the lead screw to control the synchronous movement of the friction units 301 on both sides, which can ensure that the two friction units 301 abut against the travel track 100 at the same time, ensuring a clamping effect and effectively preventing slippage.

[0054] Reference Figures 1 to 4 In some embodiments of this application, the unloading vehicle 200 includes a frame, a support 201 is provided at the bottom of the frame protruding downwards, a roller 202 is rotatably disposed at the bottom of the support 201, and the horizontal height of the connecting rod 304 is higher than that of the roller 202.

[0055] Since a conveyor belt needs to be installed on the frame and materials need to be transported above it, this embodiment provides a support 201 at the lower end of the frame, creating a certain space between the main body of the frame and the travel track 100, which facilitates the installation of the connecting rod 304. Compared to placing the drive unit 303 and the connecting rod 304 on the outside of the frame, this method helps to reduce the space volume.

[0056] Reference Figure 4 In some embodiments of this application, the link 304 includes:

[0057] The first segment 3041 is parallel to the travel track 100 and is connected to the drive unit 303;

[0058] The second rod segment 3042 is horizontally and vertically connected to the end of the first rod segment 3041, and the end of the second rod segment 3042 is hinged to the friction part 301.

[0059] Understandably, the first rod segment 3041 and the second rod segment 3042 are horizontally arranged L-shaped structures. In this embodiment, the connecting rod 304 can be connected to the lead screw while the first rod segment 3041 extends along the traveling direction of the unloading vehicle 200 to avoid the drive unit 303, so that the second rod segment 3042 can extend outward to the outside of the frame to connect to the friction unit 301.

[0060] Reference Figure 3 In some embodiments of this application, the unloading vehicle 200 is equipped with a bottom idler roller 203, and the horizontal height of the connecting rod 304 is lower than that of the bottom idler roller 203. It can be understood that the bottom idler roller 203 is used to support the return section of the conveyor belt. In this embodiment, the connecting rod 304 is positioned below the bottom idler roller 203 and above the roller 202, which avoids interference and installation impact with the conveyor belt, and also avoids downward proximity to the travel track 100, thus avoiding the limitations of the inner structure and installation space of the travel track 100.

[0061] Reference Figures 1 to 6 In some embodiments of this application, a friction head 302 is provided at the lower end of the friction part 301. In the second state, the friction head 302 abuts against the web of the travel track 100. Since the travel track 100 typically includes upper and lower wing plates and a middle web plate, if the anti-slip effect is achieved by abutting against the wing plates, the friction force from the outside is difficult to maintain effectively. In this embodiment, by abutting against the web plate, the friction force can be effectively ensured, thereby ensuring the anti-slip effect.

[0062] Reference Figure 6 In some embodiments of this application, the friction head 302 has a first end face and a second end face facing the end of the travel track 100, with an obtuse angle between the first end face and the second end face. A rubber pad 3021 protrudes from the surfaces of the first end face and the second end face of the friction head 302. In the second state, the first end face and the second end face face the web and the upper wing plate of the travel track 100, respectively. With this structural configuration, the friction head 302 abuts against both the web and the upper wing plate of the travel track 100, which helps to further improve the friction force. Furthermore, since the first end face and the second end face form an obtuse angle, i.e., the second end face is inclined upwards, under the action of the drive unit 303, the second end face applies an upward force to the upper wing plate through the rubber pad 3021, which can improve the locking and fixing effect.

[0063] Reference Figure 6In some embodiments of this application, the friction part 301 is provided with a swing arm, wherein the friction head 302 is disposed at the lower end of the swing arm, and the upper end of the swing arm is hinged to the frame of the unloading vehicle 200. The swing arm includes a rod 3011, an adjusting seat 3012, and a spring 3013, wherein the lower end of the rod 3011 is provided with an external thread, and the adjusting seat 3012 is threadedly sleeved on the lower end of the rod 3011, and can be adjusted up and down by moving along the length of the rod 3011 using the thread. An adjusting cavity is provided inside the adjusting seat 3012. The friction head 302 has a connecting shaft 3022 extending into the adjusting cavity from the lower end of the adjusting seat 3012, and a retaining connector 3023 is provided enlarged on the connecting shaft 3022 within the adjusting cavity. The spring 3013 is sleeved on the connecting shaft 3022, and its two ends abut against the lower end of the adjusting seat 3012 and the retaining connector 3023.

[0064] Understandably, since the rubber pad 3021 will wear out under long-term operation, this embodiment can control the up-and-down adjustment of the friction head 302 through the adjusting seat 3012 to ensure the clamping effect. Furthermore, the friction head 302 has a certain downward floating range, allowing it to move downwards an appropriate distance when contacting the upper wing plate to ensure contact with the web plate. Simultaneously, based on the force of the spring 3013, the force between it and the upper wing plate is strengthened, further improving the clamping effect.

[0065] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
