Description

Technical Field

[0001] This utility model relates to the technical field of simple belt conveyor heads, specifically a brake device for a simple electric roller belt conveyor head. Background Technology

[0002] The electric drum conveyor belt for underground use is a type of conveying equipment widely used in underground working environments such as mines. It combines the advantages of electric drums and simple belts, and features compact structure, convenient installation, low maintenance cost, and high transportation efficiency.

[0003] The simple electric drum conveyor belt system for underground mining mainly consists of an electric drum, a belt, a frame, a tensioning device, and a drive unit. The electric drum serves as the power source, and the belt drive enables continuous material transport. This equipment is particularly suitable for short-distance, steeply inclined, or space-constrained underground roadways, effectively improving transportation efficiency and reducing labor intensity.

[0004] Currently, simple electric drum belts used in underground mines cannot be equipped with braking devices. When the simple electric drum belts are running, there is a slope, which can easily cause the belt to slip and get buried at the tail of the machine, thus causing the belt to be pressed down. Therefore, it is necessary to propose a braking device for the head of the simple electric drum belt to solve the above-mentioned problems. Utility Model Content

[0018] Please see Figures 1 to 3A simple electric roller belt conveyor head brake device includes a fixed frame 1, a top plate 102 above the fixed frame 1, two mounting parts 101 arranged in a front-to-back pattern between the left side of the upper surface of the fixed frame 1 and the top plate 102, an electric roller 2 rotatably connected between the two mounting parts 101, a brake pad 401 on the outer side of the electric roller 2, a fixed plate 4 fixedly connected to the right side of the brake pad 401, a fixed groove 403 opened at the end of the fixed plate 4 away from the brake pad 401, a support frame 103 between the fixed frame 1 and the top plate 102, an electro-hydraulic thruster 3 installed on the upper surface of the support frame 103, an output shaft 301 fixedly connected to the output end of the electro-hydraulic thruster 3, a connecting plate 5 with one end movably connected to the output shaft 301 above the support frame 103, and the other end of the connecting plate 5 located in the fixed groove 403 and movably connected to the fixed groove 403.

[0019] In this embodiment: by setting up an electro-hydraulic thruster 3, the electro-hydraulic thruster 3 can be made to work, causing the output shaft 301 to push one end of the connecting plate 5 towards the electric drum 2. The connecting plate 5 is subjected to force and, under the limitation of the U-shaped clamp 501, causes the other end of the connecting plate 5 to drive the fixed plate 4 away from the electric drum 2. This allows the brake 401 to move away from the electric drum 2 along with the fixed plate 4, thereby achieving the braking and closing of the belt. Conversely, by making the electro-hydraulic thruster 3 work, the output shaft 301 pulls one end of the connecting plate 5 away from the electric drum 2, and the connecting plate... 5. Under the force and the limitation of the U-shaped clamp 501, the other end of the connecting plate 5 drives the fixing plate 4 to move closer to the electric drum 2, so that the brake 401 moves closer to the electric drum 2 along with the fixing plate 4 until the brake 401 abuts against the outer wall of the electric drum 2, thereby realizing the opening of the belt brake. During use, when the belt stops, the brake is closed, and when the belt starts, the brake is opened. Thus, by setting the brake 401, the electro-hydraulic thruster 3 and the connecting plate 5 to cooperate with each other to form a braking device, the accident of belt burrowing at the tail of the machine can be reduced, and the belt driver can achieve the effect of simple operation, safety and reliability.

[0020] As a technical optimization of this utility model, a support base 502 is fixedly connected to the upper end face of the support frame 103, and a U-shaped clamp 501 sleeved on the outer wall of the connecting plate 5 is fixedly connected to the upper end face of the support base 502. The outer wall of the U-shaped clamp 501 is movably connected to the connecting plate 5 through a movable shaft.

[0021] In this embodiment: the U-shaped clamp 501 is installed in the middle of the outer side of the connecting plate 5, and the U-shaped clamp 501 is movably connected to the connecting plate 5, which can limit the position of the connecting plate 5 while ensuring that the connecting plate 5 can move.

[0022] As a technical optimization of this utility model, the upper end face of the fixing frame 1 and the lower end face of the top plate 102 are both fixedly connected to the connecting piece 104 which is fixedly connected to the support frame 103.

[0023] In this embodiment, the support frame 103 can be fixed by the connector 104, so that the support frame 103 can be installed stably.

[0024] As a technical optimization of this utility model, the right side of the electro-hydraulic thruster 3 is connected to the connecting piece 104 located on the right side by bolts.

[0025] In this embodiment, the electro-hydraulic thruster 3 can be installed and fixed by bolts.

[0026] As a technical optimization of this utility model, a reinforcing plate 402 is fixedly connected between the outer wall of the fixing plate 4 and the brake skin 401.

[0027] In this embodiment, the reinforcing plate 402 can be used to reinforce the fixing plate 4 and the gate skin 401.

[0028] As a technical optimization of this utility model, the brake skin 401 has an arc-shaped structure.

[0029] In this embodiment, the arc-shaped structure of the brake skin 401 allows for better contact with the electric roller 2.

[0030] Working principle: First, connect the electro-hydraulic thruster 3 and the electric drum 2 to an external power source. By setting the electro-hydraulic thruster 3, it can be made to work, causing the output shaft 301 to push one end of the connecting plate 5 towards the electric drum 2. The connecting plate 5 is subjected to force and, under the limitation of the U-shaped clamp 501, the other end of the connecting plate 5 drives the fixed plate 4 to move away from the electric drum 2. This allows the brake 401 to move away from the electric drum 2 along with the fixed plate 4, thus achieving the braking and closing of the belt. Conversely, when the electro-hydraulic thruster 3 is made to work, it causes the output shaft 301 to pull one end of the connecting plate 5 away from the electric drum 2. When the roller 2 moves in a certain direction, the connecting plate 5 is subjected to force and, under the limitation of the U-shaped clamp 501, the other end of the connecting plate 5 drives the fixing plate 4 to move closer to the electric roller 2. This allows the brake 401 to move closer to the electric roller 2 along with the fixing plate 4 until the brake 401 abuts against the outer wall of the electric roller 2, thereby opening the brake on the belt. During use, when the belt stops, the brake is closed; when the belt starts, the brake is opened. Thus, by setting the brake 401, the electro-hydraulic thruster 3, and the connecting plate 5 to cooperate with each other to form a braking device, the accident of the belt getting stuck at the tail of the machine can be reduced, achieving the effect of simple, safe, and reliable operation for the belt driver.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
