Description

Technical Field

[0001] The utility model relates to the technical field of lock bucket valves, in particular to an emergency switch tool for a lock bucket valve. Background Art

[0002] The lock hopper valve is usually installed on the pipeline for conveying pulverized coal. The lock hopper valve is driven to open and close by an actuator. For example, the Chinese utility model patent with application number 202120811764.4 provides an ash-conveyor lock hopper valve that prevents stuffing box scaling. The valve stem drives the valve ball to rotate, and the actuator is used to drive the valve stem to rotate; however, frequent on and off operations cause the lock hopper valve to often fail in the valve actuator during operation.

[0003] This results in that during actual operation, when the actuator of the lock hopper valve fails, it takes about 4 hours to replace it online. During the maintenance process, the lock hopper valve cannot be controlled to open and close in time, and slag cannot be discharged normally, which leads to system reduction and unplanned shutdown of the gasifier, causing economic losses. Utility Model Content

[0004] The purpose of the utility model is to provide an emergency opening and closing tool for a lock bucket valve, so as to solve the technical problem that the lock bucket valve actuator cannot be opened and closed in time when a fault occurs.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A lock bucket valve emergency switch tool comprises a clamping ring, a rotating handle and a clamping mechanism, wherein the clamping ring is sleeved on the outside of the clamping mechanism, and the rotating handle is connected to the outer wall of the clamping ring.

[0007] It is further defined that a reinforcing rib is provided between the clamping ring and the rotating handle.

[0008] It is further defined that an extension handle is provided on the rotating handle, and the extension handle is detachably connected to the rotating handle.

[0009] It is further defined that the clamping mechanism includes a clamping sleeve, an inner wall of the clamping sleeve is provided with a clamping groove, and the clamping sleeve is detachably connected to the clamping ring.

[0010] It is further defined that there are multiple clamping grooves, and the multiple clamping grooves are arranged at equal intervals around the axis of the clamping sleeve.

[0011] It is further defined that the clamping mechanism also includes a connecting ring, which is sleeved on the outside of the clamping sleeve, and the clamping ring is detachably connected to the clamping sleeve through the connecting ring.

[0012] It is further defined that the connecting ring and the clamping ring are both provided with locking holes, and the locking holes are located on the outside of the clamping sleeve.

[0013] It is further defined that there are multiple locking holes, and the multiple locking holes are arranged at equal intervals around the axis of the clamping sleeve.

[0014] It is further defined that the number of the locking holes is 4 to 8.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. The utility model locks the valve body shaft on the lock bucket valve through the clamping mechanism, and then drives the clamping ring sleeved on the outside of the clamping mechanism to rotate through the handle, so that the operator can manually complete the switch control of the lock bucket valve. When the lock bucket valve actuator fails for maintenance, the staff can manually complete the emergency slag discharge according to the needs, ensure the normal operation of the gasifier, avoid the unplanned shutdown of the gasifier, and thus meet the actual use needs.

[0017] 2. The present invention can improve the structural strength of the rotating handle and ensure its stability and reliability during the rotation process by providing reinforcing ribs between the rotating handle and the clamping ring; at the same time, an extended handle can also be provided on the rotating handle, which is conducive to reducing the difficulty of rotation in areas with sufficient space and improving the efficiency of manual opening and closing.

[0018] 3. The clamping ring in the utility model is detachably connected to the clamping sleeve through the connecting ring. On the one hand, it is convenient to adjust the clamping angle with the valve body shaft through the clamping sleeve, so as to avoid the need to set the turning handle to follow the rotation direction of the valve body shaft, thereby adapting to the manual switching of the lock bucket valve in different positions; on the other hand, the clamping sleeve of corresponding specifications can be replaced according to the actual specifications of the valve body shaft, so as to facilitate the use of the combination and further meet the actual work needs.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] refer to Figure 1 This embodiment provides a locking bucket valve emergency switch tool, including a clamping ring 1, a rotating handle 2 and a clamping mechanism 3.

[0026] Among them, the clamping ring 1 is sleeved on the outside of the clamping mechanism 3, the clamping ring 1 is connected to the clamping mechanism 3, the clamping mechanism 3 is used to connect with the valve body shaft (that is, the valve stem) of the lock bucket valve, and the rotating handle 2 is connected to the clamping ring 1. The operator uses the rotating handle 2 to drive the clamping ring 1 to rotate, and then drives the valve body shaft to rotate through the clamping mechanism 3. Therefore, when the actuator of the lock bucket valve fails, the operator can connect the clamping mechanism 3 to the valve body shaft after disassembling the actuator. Then, according to the switching time of the lock bucket valve, the operator pushes the rotating handle 2 to perform an emergency switch on the lock bucket valve, thereby ensuring that the gasifier works normally and stably to meet actual usage needs.

[0027] Specifically, the clamping mechanism 3 and the valve body shaft are preferably connected in a clamping manner, which facilitates the connection and disassembly of the operator, reduces work difficulty, and improves work efficiency.

[0028] The clamping ring 1 can be selected as a rectangular structure or a polygonal structure, but in order to avoid the outer wall of the clamping ring 1 from colliding with the external structure on site or to meet the use requirements of a relatively small space, the clamping ring 1 is preferably a circular structure.

[0029] The clamping ring 1 can be made of a steel plate with a thickness of 40 mm, and the rotating handle 2 can be made of a steel plate with a thickness of 40 mm to 45 mm.

[0030] In order to rotate the rotating handle 2 in an area with relatively spacious space, it is preferred to provide an extension handle 5 on the rotating handle 2, thereby reducing the difficulty of rotating the rotating handle 2, reducing work intensity, and meeting actual work needs.

[0031] refer to Figure 2 The extension handle 5 is detachably connected to the rotating handle 2. For example, the extension handle 5 can be selectively connected to the rotating handle 2 by plugging, folding or snapping.

[0032] In order to improve the structural stability of the rotating handle 2, a reinforcing rib 4 is provided between the rotating handle 2 and the clamping ring 1. The reinforcing rib 4 is located on opposite sides of the rotating handle 2 to ensure stability and reliability when manually opening and closing the lock bucket valve.

[0033] Further explanation: the clamping mechanism 3 includes a clamping sleeve 6, which can be fixedly connected or detachably connected to the clamping ring 1. Preferably, the clamping ring 1 and the clamping sleeve 6 are detachably connected, which is convenient for disassembly and storage while also convenient for adjusting the connection angle with the clamping sleeve 6.

[0034] The clamping sleeve 6 is clamped with the valve body shaft, and a clamping groove 7 can be optionally opened on the inner wall of the clamping sleeve 6. After the clamping sleeve 6 is sleeved on the valve body shaft, the keyway on the valve body shaft is aligned with the clamping groove 7, and then the clamping sleeve 6 is clamped with the valve body shaft using a pin key, thereby ensuring stable driving of the valve body shaft.

[0035] In order to improve the reliable connection between the clamping sleeve 6 and the valve body shaft, multiple clamping grooves 7 can be opened. The multiple clamping grooves 7 are arranged at intervals around the axis of the clamping sleeve 6 so that the number of clamping grooves 7 corresponds to the key grooves on the valve body shaft.

[0036] The number of the clamping slot 7 can also be selected to be one.

[0037] Similarly, the disassembly connection between the clamping ring 1 and the clamping sleeve 6 can be selected by setting multiple clamping teeth on the outside of the clamping sleeve 6, and providing matching grooves that match the multiple clamping teeth on the inner wall of the clamping ring 1. After the clamping sleeve 6 is stably connected to the valve body shaft, the clamping ring 1 selects a suitable angle to clamp with the clamping sleeve 6, so that the rotating handle 2 is located in an area that is convenient for rotation, which is convenient for rotation; when there are obstructions during the rotation of the handle 2, the clamping ring 1 can be selected to be taken out of the rotation angle and re-clamped with the clamping sleeve 6, and the rotating handle 2 is continued to be pushed to rotate until the lock bucket valve is opened and closed.

[0038] In order to cope with the opening and closing of lock bucket valves of different specifications, the clamping sleeves 6 with different inner diameters can be selected, and the outer diameters of the clamping sleeves 6 can be selected to be consistent, so that the clamping ring 1 can be universal; the wall thickness of the clamping sleeves 6 can also be selected to be consistent. At this time, the inner diameter of the clamping ring 1 matches the outer diameter of the clamping sleeve 6, and the clamping sleeve 6 needs to be used in conjunction with the clamping ring 1.

[0039] refer to Figure 3 Preferably, the clamping mechanism 3 also includes a connecting ring 8, which is sleeved on the outside of the clamping sleeve 6 and welded to the clamping sleeve 6. Preferably, a plurality of locking holes 9 are opened on the connecting ring 8, and the same number of locking holes 9 are also opened on the clamping ring 1.

[0040] When in use, first clamp the clamping sleeve 6 with the connecting ring 8 to the valve body shaft, and then adjust the connection angle between the clamping ring 1 and the connecting ring 8 according to the position of the rotating handle 2 to facilitate the operator to push the rotating handle 2.

[0041] Subsequently, the locking hole 9 on the clamping ring 1 and the locking hole 9 on the connecting ring 8 are limited by the pin shaft, so that the clamping ring 1 and the connecting ring 8 are stably connected, making it convenient for the operator to perform emergency switching on the lock bucket valve.

[0042] The connection stability between the clamping ring 1 and the clamping sleeve 6 can be improved by providing the connecting ring 8, thereby ensuring safe and reliable use.
