Description

Technical Field

[0001] This invention relates to the field of belt conveyor technology, and more specifically, to a belt conveyor frame adjustment device. Background Technology

[0002] In coal mines, the process of tunneling, feeding, and unloading coal involves the tunneling machine transmitting the coal to the surface via a transfer belt conveyor and a transport belt. Therefore, the condition of the belt conveyor during tunneling and feeding is crucial to the progress of feeding. Improper adjustment of the belt conveyor frame will inevitably cause deviation, coal spillage, or equipment damage. The spilled coal needs to be cleaned up by workers, and the damaged equipment requires maintenance, impacting production and increasing the workload of the workers.

[0003] In related technologies, the methods for adjusting the conveyor belt in underground wells include using pry bars, conveyor shifters, and manual hoists. These methods are inefficient and inconvenient to carry. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art. To this end, embodiments of the present invention provide a belt conveyor frame adjustment device that is convenient to use and highly efficient.

[0005] The belt conveyor frame adjustment device of this embodiment includes:

[0006] Frame;

[0007] A support assembly connected to the frame includes a first support member and a second support member. The support assembly has a first support state and a second support state. In the first support state, the first support member moves away from the frame and abuts against the ground, and the second support member moves away from the frame and abuts against the conveyor belt frame. In the second support state, the first support member moves closer to the frame and is spaced away from the ground, and the second support member moves closer to the frame and is spaced away from the conveyor belt frame.

[0008] A drive assembly, comprising a drive unit connected to at least a portion of the support assembly, the drive unit being movable along a height direction orthogonal to the frame, so as to drive the conveyor belt frame to move in a second supported state.

[0009] The belt conveyor frame adjustment device of this invention can place the support component under the belt conveyor frame and change the support component from the first support state to the second support state, thereby realizing the function of supporting the frame and the belt conveyor frame. Then, the drive component is used to realize the movement of the belt conveyor frame, avoiding the need for construction personnel to move it manually.

[0010] Therefore, the belt conveyor frame adjustment device of the present invention is convenient to use and highly efficient.

[0011] In some embodiments, the support assembly includes a lifting member and a clamping member. The lifting member is connected to the frame and is movable along the height direction of the frame. The clamping member is connected to the lifting member and is movable along the width direction of the frame. The driving unit is connected to the clamping member to drive the clamping member to move along the width direction of the frame. In the second support state, at least a portion of the clamping member abuts against the conveyor belt frame and is movable along the width direction of the frame.

[0012] In some embodiments, the clamping member includes a clamping base, a clamping platform, a first clamping part, and a second clamping part. The clamping base is connected to the lifting member and is movable along the width direction of the frame. The clamping platform is connected to the clamping base and is movable along the height direction of the frame. The first clamping part and the second clamping part are connected to the clamping platform and are arranged opposite to each other in the width direction of the frame. The first clamping part is rotatable about a first axis, and the second clamping part is rotatable about a second axis. The first axis and the second axis are parallel, and both the first axis and the second axis are orthogonal to the height direction of the frame.

[0013] In some embodiments, the support assembly further includes a first elastic element, a first end of which is connected to the clamping platform and a second end of which is connected to the clamping base. In the second support state, the first elastic element is in a compressed state.

[0014] In some embodiments, a second elastic member is further included, with a first end connected to the first clamping portion and a second end connected to the clamping base. In the second support state, the second elastic member is in a stretched state.

[0015] In some embodiments, the center of gravity of the first clamping part is located on the side of the first axis away from the clamping platform, and the center of gravity of the second clamping part is located on the side of the second axis away from the clamping platform.

[0016] In some embodiments, the first support member is connected to the lifting member, and the second support member is arranged opposite to the first support member in the height direction of the frame. In the second support state, the first support member drives the lifting member to move, and the second support member contacts the ground to support the frame and space the frame from the ground.

[0017] In some embodiments, the moving speed of the second support member is greater than the moving speed of the first support member.

[0018] In some embodiments, the second support member further includes a support base plate, which is connected to the bottom ball joint of the second support member.

[0031] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] like Figures 1-5As shown, the belt conveyor frame adjustment device of this embodiment includes: frame 1, support component 2 and drive component 3.

[0033] Support assembly 2 is connected to frame 1. Support assembly 2 includes a first support member 21 and a second support member 22. Support assembly 2 has a first support state and a second support state. In the first support state, the first support member 21 moves away from frame 1 and abuts against the ground, and the second support member 22 moves away from frame 1 and abuts against the belt conveyor frame 100. In the second support state, the first support member 21 moves closer to frame 1 and is spaced away from the ground, and the second support member 22 moves closer to frame 1 and is spaced away from the belt conveyor frame 100. Drive assembly 3 includes a drive unit 31, which is at least partially connected to support assembly 2. Drive unit 31 is driven along a direction orthogonal to the height of frame 1 (e.g., ...). Figure 1 The vertical direction of the conveyor belt is movable so that it can move the conveyor belt frame 100 in the second support state.

[0034] Specifically, such as Figures 1-5 As shown, the frame 1 has an installation area that runs through the frame 1 in the vertical direction. The first support member 21 and the second support member 22 are both located in the installation area, and the extension direction of the first support member 21 and the second support member 22 is consistent with the vertical direction.

[0035] It is understandable that when changing from the first support state to the second support state, the first support member 21 moves upward so as to contact the belt conveyor frame 100 and perform the function of supporting the belt conveyor frame 100, and the second support member 22 moves downward so as to contact the ground and perform the function of supporting the frame 1.

[0036] In other words, the conveyor frame adjustment device of this embodiment can place the support component 2 below the conveyor frame 100 and change the support component 2 from the first support state to the second support state, thereby realizing the function of supporting the frame 1 and the conveyor frame 100. Then, the drive component 3 is used to move the conveyor frame 100, avoiding the need for construction personnel to move it manually.

[0037] Therefore, the belt conveyor frame adjustment device of the present invention is convenient to use and highly efficient.

[0038] It should be noted that the first support member 21 and the second support member 22 can be devices with telescopic functions, such as cylinders or hydraulic cylinders, or, for example... Figure 1 and Figure 2As shown, both the first support member 21 and the second support member 22 are racks. A rotating shaft arranged in the front-to-back direction is provided in the installation area. The rotating shaft is driven by a motor and has gears that mesh with the first support member 21 and the second support member 22 respectively. When the motor is started, the first support member 21 can be moved upward and the second support member 22 can be moved downward, thereby realizing the function of supporting the belt conveyor frame 100.

[0039] In some embodiments, the first support member 21 is connected to the lifting member 23, and the second support member 22 is arranged opposite to the first support member 21 in the height direction of the frame 1. In the second support state, the first support member 21 drives the lifting member 23 to move, and the second support member 22 contacts the ground to support the frame 1 and separate the frame 1 from the ground.

[0040] It is understandable that, such as Figure 1 and Figure 2 As shown, the first support member 21 is located on the left side of the rotating shaft, and the second support member 22 is on the right side of the rotating shaft. When the rotating shaft rotates, the first support member 21 moves upward and the second support member 22 moves downward.

[0041] Preferably, the moving speed of the second support member 22 is greater than the moving speed of the first support member 21. That is, during the process of the support assembly 2 changing from the first support state to the second support state, since the moving speed of the second support member 22 is greater than the moving speed of the first support member 21, the second support member 22 contacts the ground more quickly, thereby realizing the function of supporting the frame 1 and providing protection for the first support member 21 to support the belt conveyor frame 100.

[0042] Optionally, the number of teeth of the gear meshing with the first support member 21 is less than the number of teeth of the gear meshing with the second support member 22.

[0043] In some embodiments, the second support member 22 further includes a support base plate 221, with the support base plate 221 and the bottom ball joint of the second support member 22. It is understood that this facilitates full contact between the support base plate 221 and the ground when the ground is uneven, ensuring effective support.

[0044] Optionally, such as Figure 4 and Figure 5 As shown, the bottom of the frame 1 is also equipped with multiple casters 4. In the first support state, the casters are in contact with the ground to facilitate the movement of the frame 1. In the second support state, the support base plate 221 is in contact with the ground to prevent the frame 1 from moving.

[0045] In addition, the drive assembly 3 can be a device with telescopic function such as a cylinder or a hydraulic cylinder. The drive part 31 extends in the left and right direction so that after the first support member 21 supports the belt conveyor frame 100, the drive part 31 moves in the left and right direction and drives the belt conveyor frame 100 to move in the left and right direction, thereby realizing the adjustment function of the belt conveyor frame 100.

[0046] In some embodiments, the support assembly 2 includes a lifting member 23 and a clamping member 24. The lifting member 23 is connected to the frame 1 and is movable along the height direction of the frame 1. The clamping member 24 is connected to the lifting member 23 and is movable along the width direction of the frame 1 (e.g., ...). Figure 1 The drive unit 31 is connected to the clamping member 24 to drive the clamping member 24 to move along the width direction of the frame 1. In the second support state, at least a portion of the clamping member 24 abuts against the belt conveyor frame 100 and is movable along the width direction of the frame 1.

[0047] Specifically, such as Figure 1 As shown, the lifting member 23 has a first connecting shaft, and the frame 1 has a first connecting hole that matches the first connecting shaft. The bottom of the lifting member 23 is connected to the top of the first support member 21, so that when the first support member 21 moves in the vertical direction, it can drive the lifting member 23 to move in the vertical direction. The bottom of the clamping member 24 has a protrusion, and the top of the lifting member 23 has a groove that matches the protrusion. The bottom protrusion of the clamping member 24 fits into the groove, so that the clamping member 24 can move relative to the lifting member 23. The extension direction of the groove is consistent with the left-right direction. The clamping member 24 is connected to the driving part 31 so that the driving part 31 drives the clamping member 24 to move in the left-right direction.

[0048] In some embodiments, the clamping member 24 includes a clamping base 241, a clamping platform 242, a first clamping part 243, and a second clamping part 244. The clamping base 241 is connected to the lifting member 23 and is movable along the width direction of the frame 1. The clamping platform 242 is connected to the clamping base 241 and is movable along the height direction of the frame 1. The first clamping part 243 and the second clamping part 244 are connected to the clamping platform 242 and are arranged opposite to each other in the width direction of the frame 1. The first clamping part 243 is rotatable about a first axis, and the second clamping part 244 is rotatable about a second axis. The first axis and the second axis are parallel, and both the first axis and the second axis are orthogonal to the height direction of the frame 1.

[0049] Specifically, such as Figure 1 As shown, protrusions are provided on the front and rear sides of the clamping base 241. In a plane orthogonal to the left and right directions, the cross-section of the groove of the lifting member 23 is T-shaped, so that the clamping base 241 fits into the groove of the lifting member 23.

[0050] The clamping platform 242 has a second connecting shaft at its bottom, and the lifting member 23 has a second connecting hole that matches the second connecting shaft. The second connecting shaft fits into the second connecting hole, allowing the clamping platform 242 to move vertically relative to the clamping base 241. A first clamping part 243 and a second clamping part 244 are respectively located on the left and right sides of the clamping platform 242. The first clamping part 243 is connected to the clamping base 241 via a first rotating shaft, and the second clamping part 244 is connected to the clamping base 241 via a second rotating shaft. The lower ends of both the first clamping part 243 and the second clamping part 244 are located below the clamping platform 242. The axis of the first rotating shaft is the first axis, and the axis of the second rotating shaft is the second axis. The extending directions of both the first and second rotating shafts are consistent with the front-to-back direction.

[0051] It is understandable that, such as Figures 3-5 As shown, in the second supported state, the upper ends of both the first clamping part 243 and the second clamping part 244 extend away from the clamping platform 242, so that a placement area for placing the conveyor belt frame 100 is formed between the first clamping part 243, the clamping platform 242, and the second clamping part 244. Figures 1-5 As shown, when the conveyor frame 100 presses on the clamping platform 242, the clamping platform 242 moves downward under force. The bottom of the clamping platform 242 drives the lower ends of the first clamping part 243 and the second clamping part 244 to move. The first clamping part 243 and the second clamping part 244 rotate so that the upper ends of the first clamping part 243 and the second clamping part 244 move toward the conveyor frame 100 until the upper ends of the first clamping part 243 and the second clamping part 244 press against the conveyor frame 100 to ensure the stability of the conveyor frame 100.

[0052] Preferably, the upper surface of the clamping platform 242 is provided with multiple anti-slip protrusions, which are arranged at intervals along the left and right directions.

[0053] Optionally, the support assembly 2 further includes a first elastic element 25, the first end of which is connected to the clamping platform 242, and the second end of which is connected to the clamping base 241. In the second support state, the first elastic element 25 is in a compressed state.

[0054] Specifically, such as Figures 3-5As shown, in the second support state, after the conveyor frame 100 is placed on the clamping platform 242, the clamping platform 242 will move downward under force, and the first elastic member 25 will be compressed. During the process of changing from the second support state to the first support state, the first support member 21 moves downward, and the left and right side walls of the conveyor frame 100 overcome the friction between the first clamping part 243 and the second clamping part 244, causing the conveyor frame 100 to separate from the clamping platform 242. The clamping platform 242 moves upward under the elastic force of the first elastic member 25, thereby releasing the action of the first clamping part 243 and the second clamping part 244 clamping the conveyor frame 100, and thus realizing the separation of the conveyor frame 100 from the clamping platform 242.

[0055] Optionally, the first elastic element 25 can be a spring, and the first elastic element 25 is fitted around the periphery of the first connecting shaft.

[0056] Optionally, the belt conveyor frame adjustment device of the present invention further includes a second elastic member 26. The first end of the second elastic member 26 is connected to the first clamping part 243, and the second end of the second elastic member 26 is connected to the clamping base 241. In the second support state, the second elastic member 26 is in a stretched state.

[0057] Optionally, such as Figure 1 and Figure 2 As shown, the second elastic element 26 can also be a spring. When the conveyor frame 100 is placed on the clamping platform 242, the first clamping part 243 and the second clamping part 244 clamp the conveyor frame 100. At this time, the second elastic element 26 is in a stretched state. During the process of changing from the second support state to the first support state, when the clamping platform 242 moves upward, the upper end of the first clamping part 243 rotates away from the clamping platform 242 under the elastic force of the second elastic element 26, thereby releasing the action of the first clamping part 243 and the second clamping part 244 clamping the conveyor frame 100.

[0058] Preferably, such as Figure 1 and Figure 2 As shown, a second elastic member 26 is provided between the second clamping part 244 and the clamping base 241, that is, one end of the second elastic member 26 is connected to the second clamping part 244, and the other end of the second elastic member 26 is connected to the clamping base 241.

[0059] Preferably, the center of gravity of the first clamping part 243 is located on the side of the first axis away from the clamping platform 242, and the center of gravity of the second clamping part 244 is located on the side of the second axis away from the clamping platform 242.

[0060] Understandably, during the process of changing from the second support state to the first support state, when the clamping platform 242 moves upward, the first clamping part 243 and the second clamping part 244, under the action of the elastic force of the second elastic member 26 and the action of their own center of gravity, can further rotate the first clamping part 243 and the second clamping part 244 rapidly away from the clamping platform 242.

[0061] Optionally, there are multiple support components 2, which are arranged at intervals along the width direction of the frame 1.

[0062] Preferably, such as Figure 1 As shown, multiple support components 2 form a support group, and there are multiple support groups, which are arranged at intervals along the front-to-back direction.
