Technical Field
[0001] This utility model belongs to the technical field of mining equipment and relates to a belt conveyor adjustment device. Background Technology
[0002] In underground working environments, the tunnel floor is generally uneven. This problem directly makes it difficult to keep the installed conveyor belt frame straight, so it is often necessary to support the conveyor belt H-frame.
[0003] Currently, the traditional method for adjusting the H-frame of a conveyor belt is to use a chain hoist to lift the belt frame. However, this method has many drawbacks in practical applications. The chain hoist lifting operation is cumbersome, requiring a series of complex steps such as hooking, adjusting the chain length, and slowly lifting, which consumes a lot of time and manpower. Moreover, due to the complexity of the steps, operational errors are prone to occur during operation, posing safety hazards. At the same time, the chain hoist equipment itself is relatively bulky, making it extremely inconvenient to transport and install in the narrow and complex underground tunnel environment, affecting work efficiency.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0025] This utility model relates to an auxiliary adjustment device for belt frames, such as... Figure 1 As shown, the device includes a pry bar 1, which serves as the main force-applying component. It generates prying force through the lever principle to pry the belt H-frame. One end of the pry bar 1 is equipped with a lever hook 2 to hook onto the belt H-frame, providing a point of force for prying. The other end of the pry bar 1 is a handle. The bar body of the pry bar 1 is rotatably connected to a bracket 3, which provides a stable support base. By setting up the pry bar 1 and cooperating with the lever hook 2 and the bracket 3, a prying force is generated through the lever principle to pry the belt H-frame, thus supporting the belt H-frame and ensuring smooth support work. This method is simple and convenient, and can be operated by a single person. It replaces the traditional chain hoisting and adjusting belt H-frame, effectively solving the problems of cumbersome operation and low efficiency of the traditional chain hoisting and adjusting belt H-frame.
[0026] A counterweight ring 4 is provided at the end of the pry bar 1 near the handle. By increasing the weight at one end of the pry bar 1, the balance of the pry bar 1 is adjusted, providing a reverse torque when prying, making the prying operation more effortless and stable. At the same time, after the belt H-frame is lifted, the generated reverse torque can balance the weight of the belt H-frame itself, keeping the belt H-frame stable at the raised height and preventing it from falling back. This allows sufficient time for subsequent support work, making it easier to support the belt H-frame and ensuring the smooth progress of the support work. It is simple and convenient to operate by a single person, replacing the cumbersome chain hoist, reducing both safety risks and the labor intensity of employees.
[0027] The lever hook 2 includes a hook 203 that hooks onto the belt H frame, providing a point of leverage for prying and facilitating the application of force. The straight handle of the hook 203 is sleeved on one end of the support beam telescopic cylinder 201, and the other end of the support beam telescopic cylinder 201 is perpendicularly fixed to the pry bar 1. The straight handle of the hook 203 is coaxial with the support beam telescopic cylinder 201.
[0028] Both the straight handle of the hook 203 and the side wall of the telescopic cylinder 201 have several telescopic holes 202 distributed along the axial direction. The straight handle of the hook 203 is bolted to the telescopic cylinder 201 through the telescopic holes 202. The opening direction of the telescopic holes 202 on the straight handle of the hook 203 and the side wall of the telescopic cylinder 201 is perpendicular to their respective axial directions. The straight handle of the hook 203 and the telescopic cylinder 201 cooperate with each other to realize the telescopic adjustment of the hook 203 on the telescopic cylinder 201. By adjusting the extension length of the hook 203, the position and height of the force point can be flexibly changed, which is convenient for accurately hooking the belt H-frame in different spatial layout working conditions, enhancing the environmental adaptability and operational flexibility of the device.
[0029] The pry bar 1 has several adjustment holes 5 that pass through the bar body along its axial direction. The opening direction of the adjustment holes 5 is perpendicular to the axis of the pry bar 1. The pry bar 1 is rotatably connected to the bracket 3 through the adjustment holes 5.
[0030] Support 3 includes a support cylinder, such as Figure 2 As shown, a triangular bracket 306 is provided at one end of the support cylinder, and a support base 301 is fixedly connected to the other end of the support cylinder. The support base 301 supports the pry bar 1, and a rotating rod 302 is installed on the support base 301. The rotating rod 302 is rotatably connected to the pry bar 1 through the adjustment hole 5. The rotating rod 302 serves as the rotation center of the pry bar 1, allowing the pry bar 1 to rotate around it.
[0031] The support base 301 has an overall U-shaped structure. The bottom of the support base 301 is fixedly connected to the support cylinder, and the rotating rod 302 is vertically fixed to the two inner side walls of the support base 301.
[0032] The support cylinder includes a support telescopic cylinder 304, which has a cylindrical structure. One end of the support telescopic cylinder 304 is fixedly connected to the triangular bracket 306, and the other end of the support telescopic cylinder 304 is sleeved with one end of the support telescopic rod 303. The top of the other end of the support telescopic rod 303 is fixedly connected to the bottom of the support base 301.
[0033] Both the support telescopic cylinder 304 and the support telescopic rod 303 have several support telescopic holes 305 distributed along the axial direction on their side walls. The support telescopic cylinder 304 and the support telescopic rod 303 are fixedly connected by bolts through the support telescopic holes 305. The opening direction of the support telescopic holes 305 on the support telescopic rod 303 and the support telescopic cylinder 304 is perpendicular to their respective axial directions. The support telescopic rod 303 can extend and retract within the support telescopic cylinder 304. With the support telescopic holes 305, the overall height of the support can be adjusted as needed to adapt to belt H-frames of different heights and working scenarios.
