DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] Specific embodiments are given below.

[0025] Please refer to Figures 1-4The utility model discloses a manual energy storage rod for operating mechanism, including L type pipe 1, the L type pipe 1 is rotated and is assembled with first rotary lever 2 and second rotary lever 3 through bearing, one end of first rotary lever 2 extends to the outside of L type pipe 1, the other end of first rotary lever 2 is fixedly provided with first bevel gear 4, one end of second rotary lever 3 is fixedly provided with the second bevel gear 5 of meshing with first bevel gear 4, the other end of second rotary lever 3 is equipped with the batch head 7 of cooperating with the energy storage connecting rod 02 on operating mechanism 01 through quick detachable structure 6, quick detachable structure 6 includes the square butt joint groove 601 of being set up in one end of second rotary lever 3, the inner wall of square butt joint groove 601 is set up with assembly slot 602, spring 603 is fixedly set up in assembly slot 602, one end of spring 603 is provided with lock ball 604, lock ball 604 extends out assembly slot 602, the batch head 7 includes the square butt joint block 701 of cooperating with square butt joint groove 601, one end of square butt joint block 701 is the butt joint department 702 of cooperating with energy storage connecting rod 02, the lock slot 703 of being set up with lock ball 604 is set up on square butt joint block 701, one end of first rotary lever 2 is fixedly provided with rocking handle 8.When working, due to the difference in specifications of the energy storage connecting rods 02 on different operating mechanisms 01, when manual energy storage operation is required for a specific operating mechanism 01, the worker needs to select the appropriate batch head 7 according to the specifications of the energy storage connecting rod 02 from the batch head group, align the square butt joint block 701 of the batch head 7 with the square butt joint slot 601 at the end of the second rotating rod 3, and insert it. During the insertion process, the square butt joint block 701 will extrude the lock ball 604 protruding from the assembly groove 602, so that the lock ball 604 retracts into the assembly groove 602 against the elastic force of the spring 603. When the square butt joint block 701 is completely inserted and the lock groove 703 thereon is aligned with the position of the lock ball 604, the elastic force of the spring 603 makes the lock ball 604 pop out and be clamped into the lock groove 703, achieving firm connection of the batch head 7 with the second rotating rod 3. Then the operator inserts the L-shaped pipe 1 into the narrow space and makes the butt joint part 702 on the batch head 7 butt joint with the energy storage connecting rod 02. Then the operator holds the L-shaped pipe 1 with one hand and holds the crank handle 8 with the other hand and applies a rotating force. The crank handle 8 drives the first rotating rod 2 fixed thereto to rotate. The first rotating rod 2 is installed in the L-shaped pipe 1 through a bearing, which can reduce the rotating friction and ensure flexible rotation of the first rotating rod 2. The first bevel gear 4 at the end of the first rotating rod 2 rotates synchronously with the first rotating rod 2. Since the first bevel gear 4 and the second bevel gear 5 are meshed with each other, the rotation of the first bevel gear 4 drives the second bevel gear 5 to rotate, and in turn drives the second rotating rod 3 to rotate. The second rotating rod 3 drives the batch head 7 to rotate. The butt joint part 702 of the batch head 7 cooperates with the energy storage connecting rod 02 on the operating mechanism 01. The rotation of the batch head 7 makes the energy storage connecting rod 02 rotate, thereby completing the manual energy storage of the gasholder operating mechanism. The quick disassembly and assembly structure 6 of the utility model enables the batch head 7 to be quickly replaced to adapt to energy storage connecting rods 02 of different specifications, which greatly improves the universality of the energy storage connecting rod, eliminates the need to equip each operating mechanism 01 with a dedicated energy storage connecting rod, reduces equipment cost and management difficulty, and the quick disassembly and assembly structure 6 is simple and convenient to operate, improves work efficiency, and the design of the L-shaped pipe 1 can make the energy storage connecting rod be used in narrow operating space compared with the conventional Z-shaped structure. It can bypass obstacles, so that the batch head 7 accurately butt joints with the energy storage connecting rod 02 on the operating mechanism 01, and expands the use range of the energy storage connecting rod.

[0026] Further, one end edge of the square butt block 701 is provided with an arc-shaped chamfer 7011; in operation, when the head 7 is replaced and the square butt block 701 is inserted into the square butt groove 601, the arc-shaped chamfer 7011 of the one end edge of the square butt block 701 first contacts the edge of the square butt groove 601, the arc-shaped chamfer 7011 plays a guiding role to guide the square butt block 701 to enter the square butt groove 601 more accurately, and as the insertion process advances, the arc-shaped chamfer 7011 also avoids the hard contact between the square butt block 701 and the lock ball 604, when the square butt block 701 approaches the lock ball 604, the arc-shaped chamfer 7011 presses the lock ball 604 in a smooth manner, so that the lock ball 604 gradually shrinks into the assembly groove 602 against the elastic force of the spring 603, instead of direct rigid collision, at the same time, the arc-shaped chamfer 7011 makes the contact between the square butt block 701 and the square butt groove 601 more smooth, reduces the jamming phenomenon caused by the direct collision between the edges of the square butt block 701 and the square butt groove 601, and can disperse the pressure during insertion, avoid local excessive pressure to cause damage to the parts, so that the replacement process of the head 7 is more smooth, and the comfort of work is improved.

[0027] Further, the L-shaped pipe 1 is sleeved with a handheld anti-skid sleeve 9; in operation, the operator holds the handheld anti-skid sleeve 9 on the L-shaped pipe 1 when operating the energy storage connecting rod, the handheld anti-skid sleeve 9 is made of a material with high friction coefficient, when the hand contacts the handheld anti-skid sleeve 9, the friction between the hand and the handheld anti-skid sleeve 9 is increased, and the texture of the anti-skid sleeve has a certain elasticity, can better fit the shape of the hand, further increase the contact area, thereby improve the friction, prevent the hand from sliding on the L-shaped pipe 1, and ensure that the operator can stably control the energy storage connecting rod to operate.
