Description

Technical Field

[0001] This application relates to the field of wind protection technology for belt conveyors, and in particular to a quick-release windproof pressure bar mechanism suitable for typhoon or tornado conditions. Background Technology

[0002] Belt conveyors are often used for material transport in ports, mines, factories and other places. However, in severe weather conditions such as typhoons or tornadoes, belt conveyors are easily affected by strong winds, which can cause the conveyor belt to shift or even be damaged. To protect the conveyor belt from the impact, windproof devices are usually installed on the conveyor belt to ensure the production efficiency and safety of the conveyor belt.

[0003] The prior art disclosed in the current announcement number CN212739437U is a windproof pressure bar mechanism, which includes two upright columns and a grooved wind clamp that fits the surface of the belt. A wind clamp rocker arm is provided at one end of the grooved wind clamp. By rotating the wind clamp rocker arm, the grooved wind clamp is rotated to press the surface of the belt. At the same time, slots are provided on both the wind clamp rocker arm and the upright columns, and the grooved wind clamp is fixed by fixing the insertion rod.

[0004] However, in this existing technical solution, locking the grooved wind clamp requires the fixing rod to be precisely aligned and inserted into the slot. In emergency situations or windy weather, the difficulty of alignment will be greatly increased, which seriously affects the locking efficiency. Utility Model Content

[0005] To make locking the windproof mechanism easier, this application provides a quick windproof pressure bar mechanism suitable for typhoon or tornado conditions.

[0006] A quick-release windproof pressure bar mechanism suitable for typhoon or tornado conditions includes:

[0007] Support frames are provided on both sides of the conveyor belt;

[0008] A windproof pressure bar, the two ends of which are rotatably connected to the support frame, and the bar surface of which can be in close contact with the conveyor belt surface;

[0009] A rotary locking component includes a handle and a ratchet. The handle is fixedly connected to one end of the windproof pressure rod, and the ratchet is fixedly connected to the support frame. The handle also includes a ratchet tooth and a control lever. The ratchet tooth is fixed to one end of the control lever, and an elastic element is connected between the control lever and the handle. Under the action of the elastic potential energy of the elastic element, the control lever controls the engagement of the ratchet tooth and the ratchet wheel by manipulating the position of the ratchet tooth.

[0010] By adopting the above technical solution, no other alignment parts are needed when rotating the windproof lever to the working position. The operator can directly control the engagement between the ratchet and the ratchet by pressing or releasing the control lever, thereby realizing the release and locking of the windproof lever. This makes manual operation more flexible and reliable, and the locking or unlocking action can be completed quickly even in an emergency. This simplifies the locking and unlocking process of the windproof lever and greatly improves the operating efficiency.

[0011] Preferably, the ratchet is provided with a mark, and the handle is provided with an indicator arrow, the indicator arrow being aligned with the mark when the windproof pressure bar is in contact with the belt surface.

[0012] By adopting the above technical solution, when the windproof pressure bar is pressed against the belt surface, the operator can determine whether the windproof pressure bar is locked in the correct position by judging whether the indicator arrow is aligned with the mark, thereby improving the locking efficiency and accuracy of the windproof pressure bar.

[0013] Preferably, the ratchet is provided with a recessed hole on the side away from the windproof pressure bar, and the control lever is also fixedly connected with a pin. When the windproof pressure bar is close to the belt surface, the pin is engaged in the recessed hole under the elastic force of the elastic element.

[0014] By adopting the above technical solution, when the windproof pressure rod is rotated to the correct position, the pin automatically engages with the concave hole under the action of elasticity to complete the position determination. This not only eliminates the alignment deviation caused by human eye error, but also ensures that windproof measures can be quickly completed in emergency situations, greatly improving locking efficiency and accuracy.

[0015] Preferably, it also includes a limiting member, which is fixedly connected to the other end of the windproof pressure bar and the rotary locking member. The limiting member abuts against the support frame, and the handle abuts against the side of the ratchet away from the center of the windproof pressure bar.

[0016] By adopting the above technical solution, the setting of the limiting component makes the windproof pressure bar mechanism more stable and reliable during operation, avoiding shaking or displacement caused by external forces.

[0017] Preferably, the windproof pressure rod has a protrusion at the end connected to the handle, the protrusion being polygonal in shape, and the handle having a socket that matches the shape of the protrusion.

[0018] By adopting the above technical solution, the polygonal design of the protrusion and the socket not only improves the connection stability between the windproof lever and the handle, but also ensures that the windproof lever will not rotate relative to the handle during the process of locking and unlocking, thereby improving the reliability and ease of operation of the windproof lever.

[0019] Preferably, a first locking member is provided between the protrusion and the handle and is detachably connected through the first locking member, and a second locking member is provided between the ratchet and the support frame and is detachably connected through the second locking member.

[0020] By adopting the above technical solutions, the detachable connection between the windproof pressure bar and the handle, as well as the detachable connection between the ratchet and the support frame, not only facilitates the installation and maintenance of components such as the ratchet, but also improves the flexibility and adaptability of the system.

[0021] Preferably, the handle is a long strip shape that is easy to grip.

[0022] By adopting the above technical solution, the handle is designed to be long and narrow, which not only makes it easier for operators to hold and improves the ease of operation, but also effectively reduces operational errors caused by hand fatigue, ensuring rapid response and efficient locking in emergency situations.

[0023] Preferably, the windproof pressure bar has anti-slip threads on the part of the bar that is in contact with the conveyor belt surface.

[0024] By adopting the above technical solution, the anti-slip thread increases the friction between the windproof pressure bar and the conveyor belt, effectively preventing relative slippage between the windproof pressure bar and the conveyor belt under strong wind conditions, and further improving the stability of the windproof pressure bar.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The ratchet handle design allows the windproof lever to be quickly unlocked and locked with simple manual operation in emergencies and windy weather. No additional alignment parts are required during operation. The direct cooperation between the ratchet and the lever makes the locking action more flexible and reliable. Even in emergencies, it can be operated quickly, simplifying the locking process and improving locking efficiency.

[0027] 2. The indicator arrows and markings on the handle and ratchet make locking and unlocking more intuitive and convenient for the operator, reducing the possibility of misoperation;

[0028] 3. The automatic locking mechanism between the pin on the control lever and the ratchet recess not only eliminates alignment deviations caused by human visual errors, but also ensures that the rotating locking component can quickly implement windproof measures in emergency situations, greatly improving locking efficiency and accuracy.

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0035] This application discloses a quick-release windproof pressure bar mechanism suitable for typhoon or tornado conditions.

[0036] Example 1:

[0037] Reference Figure 1 and Figure 2 A quick-release windproof lever mechanism suitable for typhoon or tornado conditions includes a support frame 1, a windproof lever 2, a rotary locking component 3, and a limiting component 4. The support frame 1 is set on both sides of the conveyor belt. The two ends of the windproof lever 2 are rotatably connected to the support frame 1. The lever surface of the windproof lever 2 can be closely attached to the surface of the conveyor belt. The rotary locking component 3 includes a handle 31 and a ratchet 32. The handle 31 is fixedly connected to one end of the windproof lever 2, and the ratchet 32 ​​is fixedly connected to the support frame 1. The handle 31 also includes a ratchet 311 and a control lever 312. The ratchet 311 is fixed to one end of the control lever 312. An elastic element 313 is connected between the control lever 312 and the handle 31. The control lever 312 manipulates the position of the ratchet 311 through the elastic element 313 to control the engagement of the ratchet 311 with the ratchet 32. The limiting component 4 is connected to the other end of the windproof lever 2 connected to the rotary locking component 3.

[0038] In this embodiment, the support frame 1 is provided with two connecting plates at the rotatable connection points with the windproof pressure rod 2 at both ends. Both connecting plates are connected to the support frame 1 by at least two bolts. Furthermore, the connecting plates are provided with round holes, through which the two ends of the windproof pressure rod 2 pass. In other embodiments, the rotatable connection between the windproof pressure rod 2 and the support frame 1 may also be provided without connecting plates, by directly using a bearing structure or opening round holes at the connection point between the support frame 1 and the windproof pressure rod 2.

[0039] In this embodiment, the shape of the windproof pressure bar 2 is pressed into a lip shape that can fit the surface of the belt. It should be noted that any shape of the windproof pressure bar 2 that can fit tightly to the surface of the belt to achieve the windproof function is within the protection scope of this application.

[0040] Specifically, the windproof lever 2 has a protrusion 21 at the end connected to the handle 31. In this embodiment, the protrusion 21 is a cuboid. In other embodiments, the protrusion 21 can be a polygon with no less than three sides. Specifically, the handle 31 has a slot 316 with a shape and size corresponding to the protrusion 21 on the side near the ratchet 32 ​​at the connection point with the windproof lever 2. The protrusion 21 engages with the slot 316 on the handle 31 to achieve stable rotation of the windproof lever 2.

[0041] Furthermore, the protrusion 21 and the handle 31 are provided with a sliding groove in the direction of the vertical windproof rod 2 axis. A first locking member 33 is detachably connected between the protrusion 21 and the handle 31. The first locking member 33 passes through the sliding groove and locks the protrusion 21 and the handle 31.

[0042] In this embodiment, the windproof pressure bar 2 is made of a circular steel pipe. In other embodiments, a rectangular steel pipe or a lightweight steel bar can also be used.

[0043] In this embodiment, the surface of the windproof pressure bar 2 is provided with anti-slip threads 6. In other embodiments, the surface of the windproof pressure bar 2 may also be provided with a flexible anti-slip sleeve with good friction performance.

[0044] In this embodiment, the handle 31 is a long strip shape that is easy to hold. In other embodiments, the handle 31 can also be a cylinder.

[0045] Specifically, the handle 31 has a cavity inside to accommodate the control lever 312 and the elastic element 313. The control lever 312 is slidably connected to the handle 31 through the cavity.

[0046] Specifically, the handle 31 is provided with an indicator arrow 314 in the direction opposite to the engagement point of the ratchet 311 and the ratchet 32.

[0047] In this embodiment, the elastic element 313 can be a spring, and the spring force can be adjusted according to actual needs.

[0048] Specifically, the ratchet 311 is located on the lever 312 near the teeth of the ratchet 32. The ratchet 311 is serrated in shape, and its size and shape match the teeth of the ratchet 32. When the ratchet 311 is engaged with the ratchet 32, the windproof lever 2 remains in the locked state. When the lever 312 is pressed, the ratchet 311 is disengaged from the ratchet 32, and the windproof lever 2 can be rotated by rotating the handle 31.

[0049] Reference Figure 2 and Figure 3Specifically, the ratchet 32 ​​has a marking 321 on its teeth, and the indicator arrow 314 is aligned with the marking 321 when the windproof pressure bar 2 is in close contact with the belt surface.

[0050] Specifically, a connector and a second locking member 5 are provided between the ratchet 32 ​​and the support frame 1 to achieve a fixed connection between the ratchet 32 ​​and the support frame 1. In this embodiment, one end of the connector is detachably connected to the ratchet 32 ​​through the second locking member 5, and the other end is connected to the connecting plate by means of bolt connection or snap-fit. In other embodiments, the ratchet 32 ​​and the support frame 1 can also be directly connected through the second locking member 5.

[0051] In this embodiment, the limiting member 4 includes an outer diameter tube and a third locking member. The inner wall of the outer diameter tube abuts against the windproof pressure rod 2, and one end of the outer diameter tube abuts against the connecting plate. The third locking member passes through the outer diameter tube and the windproof pressure rod 2 to lock both of them. By setting the limiting member 4 and the abutment between the handle 31 and the ratchet 32, the left and right limits of the windproof pressure rod 2 are realized, thereby improving the stability of the mechanism. In other embodiments, the limiting member 4 can also be an outer diameter tube welded to the windproof pressure rod 2.

[0052] The working principle of this embodiment is as follows: By setting the rotating locking component 3, the windproof pressure bar 2 mechanism of this embodiment achieves rapid and accurate locking in windy weather. When the windproof pressure bar 2 mechanism is not in operation, the section of the lip-shaped windproof pressure bar 2 that is in contact with the belt surface rotates to the top, that is, the section that is in contact with the belt surface is at its farthest point. Through the engagement of the ratchet 311 on the handle 31 with the ratchet 32, the windproof pressure bar 2 is held in this position, ensuring that the material can pass through smoothly. When encountering windy weather, the operator presses the operating lever 312 on the handle 31 by hand. The operating lever 312 compresses the elastic component 313, causing the ratchet 311 to disengage from the ratchet 32 ​​and engage in locking. The windproof pressure bar 2 naturally descends to the lowest position due to its own weight and fits tightly with the belt surface. At this time, the operator releases the operating lever 312 again, the elastic component 313 returns to its original state, and pushes the operating lever 312 back to the initial position. The ratchet 311 re-engages with the ratchet 32, thereby locking the windproof pressure bar 2. After the windy weather has passed, the same operation is performed to reset the windproof pressure bar 2.

[0053] Example 2:

[0054] This embodiment is largely the same in structure as Embodiment 1, except that in this embodiment, the handle 31 does not have an indicator arrow 314, and the ratchet 32 ​​teeth do not have a marking 321. The alignment of the handle 31 and the ratchet 32 ​​is achieved in the following manner:

[0055] Reference Figure 4Specifically, the ratchet 32 ​​is provided with a recessed hole 322 on the side away from the windproof pressure bar 2. A pin 315 is threadedly connected above the operating lever 312. The pin 315 and the recessed hole 322 are matched in shape and size. When the windproof pressure bar 2 is misaligned, the pin 315 abuts against the surface of the ratchet 32 ​​under the elastic force of the elastic element 313. When the windproof pressure bar 2 is close to the belt surface, the pin 315 on the operating lever 312 is aligned with the recessed hole 322 and automatically engages with the recessed hole 322 under the elastic force of the elastic element 313.

[0056] It should be noted that the alignment of the pin 315 and the concave hole 322 does not affect the meshing of the ratchet 311 and the ratchet 32.

[0057] The advantage of this embodiment compared to embodiment one is that, through the design of the pin 315 and the concave hole 322, this embodiment eliminates the need for visual alignment, and can quickly and accurately complete the locking operation in special circumstances such as insufficient light or obstructed vision, thus eliminating the error of visual alignment.

[0058] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
