Description

Technical Field

[0001] This utility model belongs to the field of belt conveyors, and in particular relates to a head frame suitable for belt conveyors with limited roadway length. Background Technology

[0002] Belt conveyors are continuous transportation equipment that uses a conveyor belt as the traction and load-bearing component, and are widely used in mining, ports, power, chemical and other fields.

[0003] According to the installation standards for electromechanical transportation equipment in coal mines, the distance between the belt conveyor head drive unit and the roadway must be ≥700mm (pedestrian side) or ≥500mm (non-pedestrian side), and the distance between the unloading drum and the roof must be ≥600mm. If the roadway length is insufficient, a conventional unloading arm (usually 3-5 meters in length) cannot meet the space requirements, resulting in the equipment being unable to be installed normally.

[0004] Existing technologies for solving such problems generally employ extended unloading frame technology and bridge-type split unloading arms. For example, one mine successfully achieved direct dumping of waste rock to the bottom of the waste rock pile by extending the unloading frame to 6.35 meters and using a central drive system, combined with H-beam foundations and wire rope traction. Bridge-type split unloading arms, designed for long-distance, overlapping scenarios, utilize a truss load-bearing structure, designing the unloading arm into 1.2-2 meter sections, assembled using dense bolt connections. This solves the problem of insufficient length while avoiding the risk of bending.

[0005] Therefore, existing solutions all involve extending the operating space. However, in reality, the roadway length is already short. If an extended unloading arm or a split unloading arm is used, the roadway space is still required. This cannot solve the problem of unloading coal when the roadway length is short and the conveyor length of the belt conveyor is exactly matched with the roadway length. Utility Model Content

[0006] The purpose of this invention is to provide a head frame for a belt conveyor suitable for roadways with limited length, in order to solve the problem of unloading coal when the roadway is short and the conveying length of the belt conveyor is exactly matched with the roadway.

[0007] The present invention adopts the following technical solution: a head frame for a belt conveyor with limited roadway length, the head frame being located in a roadway with limited length and capable of unloading coal without setting up an unloading arm;

[0008] The nose frame includes:

[0009] The riser is installed vertically, with its lower end resting on the roadway floor and its upper end extending upwards.

[0010] The left vertical plate of the machine head is set vertically and located on the upper side of the riser frame. Its lower end is fixedly connected to one side of the riser frame, and its upper end extends upward.

[0011] The right vertical plate of the machine head is set vertically and is located on the upper side of the extension frame. Its lower end is fixedly connected to the other side of the extension frame, and its upper end extends upward.

[0012] The drive drum is located between the left and right vertical plates of the machine head and is installed on the left and right vertical plates of the machine head; the drive drum is used to drive the belt conveyor; thereby enabling the coal on the belt to be unloaded at the drive drum.

[0013] The redirecting roller is located between the left and right vertical plates of the machine head and is installed on the left and right vertical plates of the machine head. The redirecting roller is installed close to and lower than the drive roller, and is used to change the wrap angle of the belt upward.

[0014] The riser is used to raise the horizontal position of the drive drum, so that the coal unloading point of the drive drum coincides with the coal dropping point of the belt conveyor in the next roadway.

[0015] Furthermore, upper and lower mounting holes are provided on the left and right vertical plates of the machine head at the ends away from the drive roller. The redirecting roller is installed in the two corresponding lower mounting holes. The two corresponding upper mounting holes are used to rotate the left and right vertical plates of the machine head 180° around the belt direction before installing the redirecting roller, thereby extending the service life of the left and right vertical plates of the machine head. After the lower mounting holes wear out, the redirecting roller is installed in the upper mounting holes.

[0016] The beneficial effects of this utility model are:

[0017] This invention completely removes the unloading arm, thereby matching the length of the roadway with the transport length of the belt conveyor, and uses an extension frame to raise the unloading point of the entire device, so that the unloading point of the entire device coincides with the coal drop point of the next roadway, thereby achieving high-level coal unloading.

[0018] This invention extends the service life of the left and right vertical plates of the machine head by opening upper and lower mounting holes, and then rotating the left and right vertical plates of the machine head 180 degrees along the belt direction after the lower mounting hole wears out.

[0033] Example 1

[0034] The existing DSJ80 / 40 / 2*55 belt conveyor in a certain mine, such as Figure 2 As shown in the figure, 1 represents two drive rollers and 2 represents an unloading arm. The tunnel needs to be replaced, but the tunnel length is too short to install the unloading arm of the existing DSJ80 / 40 / 2*55 belt conveyor, thus causing the construction to be halted.

[0035] The improvements made to the head frame according to this utility model are as follows:

[0036] 1. Change the dual drive of the DSJ80 / 40 / 2*55 belt conveyor to a single drive, and add a φ325 drag roller to achieve reasonable belt winding.

[0037] 2. Remove the unloading rollers and unloading arms from the DSJ80 / 40 / 2*55 belt conveyor.

[0038] 3. By utilizing the head frame of this utility model and installing the drive drum, a coal unloading height difference is achieved, thus realizing smooth coal unloading.

[0039] 4. Adding a cleaner and a coal chute at the drive drum position can effectively remove residual coal slurry at the headstock position.

[0040] After the installation of this utility model, it operated well, reducing equipment costs for the mine by 800,000 yuan, successfully solving the problem of replacing the roadway and utilizing the original conveyor, and enabling the conveyor to transport coal normally.
