Technical Field
[0001] This utility model belongs to the technical field of valve well operation, and in particular relates to a convenient and quick-operating wrench suitable for valve wells. Background Technology
[0002] A valve well is a pit (or well) set up like a small room for underground pipelines and conduits (such as water, oil, and natural gas pipelines) to facilitate the opening and closing of parts of the pipeline network or for maintenance work. Valves and other equipment are installed in this pit, making it convenient for regular inspection, cleaning, and unblocking of the pipeline, and preventing blockages. This pit is called a valve well. However, it still has the following drawbacks in actual use:
[0003] When working in a valve well, operators need to enter the valve well to open and close the valves. However, the valve well is closed for a long time and has a low oxygen content, which may pose a safety hazard to personnel entering the well.
[0004] After the valves in the valve well have been in operation for a long time, the valve handwheel and other parts may rust, causing the handwheel to be unable to turn smoothly. This makes it difficult to open and close the valves in the valve well, resulting in inconvenient operation. Utility Model Content
[0005] The purpose of this utility model is to provide a convenient and quick-operating wrench suitable for valve wells. By setting a fixed column, a movable rod and a sliding sleeve, it solves the problems of the valve well requiring operators to directly enter to open and close the valve, which is troublesome, poses safety hazards, and makes the valve prone to rust and unable to be opened and closed smoothly after long-term operation.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to a convenient and quick-operating wrench suitable for valve wells, comprising a fixed post, a movable rod, and a sliding sleeve. A fixed rod is fixed to the top of the fixed post, and a movable rod is fixed to the top of the fixed rod. The sliding sleeve is movably connected to the periphery of the movable rod. A connecting post is fixed to the top of the movable rod, and an auxiliary sleeve is fixed to the top of the connecting post. During operation, the movable rod is connected to the fixed post via the fixed rod. When the movable rod operates, the sliding sleeve is movably connected to the above. When the sliding sleeve operates, the height of the rotating ring can be changed. The auxiliary sleeve provides a position for the auxiliary rod to interact with, increasing the torque with the cooperation of the external auxiliary rod.
[0008] Furthermore, a movable sleeve is fixed to the bottom end of the fixed column, the movable sleeve being arranged vertically through the column, and the fixed rod being arranged in the shape of a frustum. When the fixed column is in operation, it abuts against the center of the top of the valve handwheel inside the valve well through the movable sleeve.
[0009] Furthermore, three fixing blocks are fixed in a circular array on the lower periphery of the movable sleeve. The fixing blocks are located at the edge of the periphery of the movable sleeve. Each fixing block has a snap-fit pin fixed on the side away from the movable sleeve. When the movable sleeve is working, the fixing blocks connect to the snap-fit pins, and the snap-fit pins are engaged in the gaps on the handwheel, allowing the handwheel to rotate.
[0010] Furthermore, a sliding groove is provided on the periphery of the movable rod. The sliding groove is vertically arranged, and the central axis of the connecting column and the central axis of the auxiliary sleeve are perpendicular to each other. When the movable rod is working, it is movably connected to the sliding block through the sliding groove.
[0011] Furthermore, a through opening is provided inside the sliding sleeve along the central axis, the movable rod is movably connected in the through opening, and a sliding block is vertically fixed in the through opening. The sliding block is movably connected in the sliding groove. When the sliding sleeve is working, the movable rod is movably connected through the through opening and the sliding block is movably connected in the sliding groove, so that the movable rod and the sliding sleeve can only change position in the vertical direction.
[0012] Furthermore, the sliding sleeve is fixed with connecting rods in a ring array around its periphery, and a rotating ring is fixed to the end of all the connecting rods away from the sliding sleeve. When the sliding sleeve is working, it is connected to the rotating ring through the connecting rods. When the rotating ring rotates, it drives the movable rod to rotate.
[0013] This utility model has the following beneficial effects:
[0014] This invention solves the problem of cumbersome operation and safety hazards caused by requiring operators to directly enter the valve well to open and close the valve when working, by setting up a fixed column, a movable rod, and a sliding sleeve. By holding the movable rod, the fixed column is inserted into the valve well, and the movable sleeve is inserted until it is positioned at the center of the handwheel at the top of the valve. Then, the locking pin is engaged in the gap on the handwheel, completing the setup. When the rotating ring is turned, the movement is transmitted through the movable rod, fixed rod, fixed column, and movable sleeve, and the locking pin engages the handwheel on the valve, making it easier to open and close the valve without requiring operators to enter the valve well.
[0015] This invention solves the problem of valves in valve wells becoming corroded and unable to open or close smoothly after long-term operation by setting up a movable rod and a sliding sleeve. When rotating the rotating ring fails to turn the valve handwheel, an auxiliary rod is taken from the working environment and inserted into the auxiliary sleeve. By rotating the auxiliary rod to a sufficiently long position, the torque is increased when rotating the auxiliary sleeve, causing the valve handwheel to initially rotate and loosen. Then, the auxiliary rod is pulled out, and the valve is opened or closed by rotating the rotating ring. When closing the valve, the valve in the valve well is tightened by rotating the auxiliary rod. This makes it easier to open valves that have partially corroded after long-term operation, and improves the applicability of the work. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1
[0025] Please see Figure 1-5 This utility model is a convenient and quick-operating wrench suitable for valve wells, including a fixed column 1, a movable rod 2, and a sliding sleeve 3. The top of the fixed column 1 is fixed with a fixed rod 104, and the movable sleeve 101 of the valve in the valve well is connected to the fixed column 1. The fixed column 1 is connected to the movable rod 2 through the fixed rod 104 at its top. The top of the fixed rod 104 is fixed with the movable rod 2, and the sliding sleeve 3 is movably connected to its periphery through the movable rod 2. The periphery of the movable rod 2 is movably connected with the sliding sleeve 3. When the sliding sleeve 3 slides, the height of the rotating ring 304 is changed. The top of the movable rod 2 is fixed with a connecting column 202, and the movable rod 2 is connected to an auxiliary sleeve 203 through the connecting column 202. The top of the connecting column 202 is fixed with the auxiliary sleeve 203. After the rod, steel pipe, etc. that assist in rotation are put into the auxiliary sleeve 203, rotation can open the valve that is difficult to rotate with a large torque.
[0026] Specifically, a movable sleeve 101 is fixed at the bottom of the fixed column 1. The movable sleeve 101 is arranged vertically, and the fixed rod 104 is arranged in the shape of a frustum. When the fixed column 1 is working, it abuts against the top center of the valve handwheel through the movable sleeve 101.
[0027] Furthermore, three fixing blocks 102 are fixed in a ring array on the lower periphery of the movable sleeve 101. The fixing blocks 102 are located at the edge of the periphery of the movable sleeve 101. Each fixing block 102 has a locking pin 103 fixed on the side away from the movable sleeve 101. When the movable sleeve 101 is working, it is connected to the locking pin 103 through the fixing blocks 102. When working, the movable rod 2 is held and the fixing pin 1 is inserted into the valve well, so that the three locking pins 103 can be locked into the rotation position of the handwheel of the valve in the valve well, and then the valve in the valve well can be opened and closed.
[0028] The operation process of this embodiment is as follows: When working, first hold the movable rod 2, then insert the fixed column 1 into the valve well. After the movable sleeve 101 is inserted into the valve well, until the movable sleeve 101 is set in the center of the handwheel at the top of the valve, then snap the locking column 103 into the gap on the handwheel to complete the setting. When the rotating ring 304 is rotated, after being transmitted through the movable rod 2, the fixed rod 104, the fixed column 1 and the movable sleeve 101, the handwheel on the valve is driven to rotate under the snapping of the locking column 103. Specific Implementation Example 2
[0029] Please see Figure 1 , 45. Based on the specific embodiment one, a sliding groove 201 is provided on the periphery of the movable rod 2. The sliding groove 201 is vertically arranged. The central axis of the connecting column 202 and the central axis of the auxiliary sleeve 203 are perpendicular to each other. When the movable rod 2 is working, it is movably connected to the sliding block 302 through the sliding groove 201.
[0030] Specifically, a through opening 301 is provided inside the sliding sleeve 3 along the central axis. The movable rod 2 is movably connected in the through opening 301. A sliding block 302 is vertically fixed in the through opening 301. The sliding block 302 is movably connected in the sliding groove 201. When the sliding sleeve 3 is working, the movable rod 2 is movably connected through the through opening 301, and the sliding block 302 is slidably connected in the sliding groove 201 on the sliding block 302, so that the sliding sleeve 3 and the movable rod 2 can only slide up and down.
[0031] Furthermore, connecting rods 303 are fixed in a ring array around the periphery of the sliding sleeve 3. All connecting rods 303 are fixed with a rotating ring 304 at the end away from the sliding sleeve 3. When the sliding sleeve 3 is working, it is connected to the rotating ring 304 through the connecting rods 303. When the rotating ring 304 rotates, it drives the sliding sleeve 3 to rotate.
[0032] The operation process of this embodiment is as follows: During operation, after the movable sleeve 101 at the bottom of the fixed column 1 is set on the valve handwheel, first rotate the rotating ring 304 to determine whether the rotation of the rotating ring 304 can drive the valve handwheel to rotate. When the rotating ring 304 can rotate, first pull the sliding sleeve 3 to drive the sliding sleeve 3 to rise and fall. When the sliding sleeve 3 rises and falls, until the sliding sleeve 3 rises to a position that the operator can easily rotate, the rotating ring 304 can be rotated to drive the valve handwheel to rotate. When rotating the rotating ring 304 cannot drive the valve handwheel to rotate, take an auxiliary rod from the working environment and insert the auxiliary rod into the auxiliary sleeve 203. When the auxiliary rod rotates to a sufficiently long position, the torque is increased when rotating the auxiliary sleeve 203, so that the valve handwheel is initially rotated and loosened. Then, pull out the auxiliary rod and rotate the rotating ring 304 to open and close the valve. When closing the valve, the valve in the valve well is tightened by rotating the auxiliary rod.
