DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the present utility model, unless otherwise expressly specified and limited, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model.

[0022] As attached Figure 1-6 As shown, a vibration isolation stand structure that is convenient for replacing vibration reduction components includes a vibration isolation stand 10 for carrying power equipment, vibration isolation feet 1 for contacting the ground are fixed on the circumference of the vibration isolation stand 10, the vibration isolation feet 1 should be arranged at least on two opposite sides of the vibration isolation stand 10, at least two are arranged on each side, and the specific number depends on the load-bearing capacity, the vibration isolation feet 1 include an outer shell, the outer shell includes an upper shell 2 fixed to the vibration isolation stand 10, the outer shell also includes a lower shell 3 for support on the ground, the upper shell 2 and the lower shell 3 are connected by a vibration reduction assembly 4, the vibration reduction assembly 4 refers to a component with an elastic structure, which is arranged between the upper shell 2 and the lower shell 3 to provide elasticity to achieve a vibration reduction effect, and at least one of the upper shell 2 and the lower shell 3 is a split structure; after the split, a gap is formed between the upper shell 2 and the lower shell 3 for taking out the vibration reduction assembly 4.

[0023] Compared with the prior art, at least one of the upper shell 2 and the lower shell 3 of the outer shell of the vibration damping assembly 4 of the utility model is a split structure, so that a gap is formed after the separation for the vibration damping assembly 4 to be taken out, which is convenient for replacing the vibration damping assembly 4 without removing the entire shell for replacement.

[0024] Furthermore, the upper shell 2 is a cover structure, and a detachable structure 21 is formed on the side of the cover structure, and a split structure is formed between the detachable structure 21 and the remaining body of the upper shell 2.

[0025] The detachable structure 21 should preferably be arranged on the side rather than the top or bottom. The purpose is that the shell needs to bear vertical pressure. Designing the top or bottom edge as a detachable structure 21 will destroy the overall structural strength, so it is preferably arranged on the side.

[0026] The upper shell 2 can be cylindrical or polygonal, preferably a quadrangular cover as shown in the figure. Figure 5 As shown, one of the side surfaces is used as a detachable structure 21, and the detachable structure 21 is fixed to the upper shell 2 by a plurality of bolts.

[0027] Further, such as Figure 4 As shown, the vibration reduction assembly 4 includes a lower support plate 41 abutting against the lower shell 3, the lower support plate 41 is fixedly connected to one end of the spring 42, the other end of the spring 42 is fixedly connected to the upper support plate 43, and the upper support plate 43 abuts against the upper shell 2; the lower support plate 41 is fixedly connected to one end of the positioning rod 5, the other end of the positioning rod 5 passes through the upper support plate 43 and the upper shell 2 in sequence, the positioning rod 5 and the upper support plate 43 are preferably clearance-fitted, and the position of the upper shell 2 through the positioning rod 5 forms a through hole 22, and the through hole 22 extends in the direction of the detachable structure 21 and forms an opening.

[0028] Furthermore, the detachable structure 21 is fixedly connected to a limiting plate 211 , and the limiting plate 211 is disposed in the through hole 22 to prevent the positioning rod 5 from falling out, and preferably, an end of the limiting plate 211 abuts against a side of the positioning rod 5 .

[0029] The purpose of the positioning rod 5 is, on the one hand, to prevent the vibration reduction assembly 4 from shifting within the outer shell during long-term use, and on the other hand, to serve as a handheld handle when taking it out, thereby driving the vibration reduction assembly 4 to be taken out as a whole. The through hole 22 opening in the direction of the detachable structure 21 serves as a guide groove for taking out, and is matched with the limit plate 211 to limit the position of the positioning rod 5 in the normal working state.

[0030] Furthermore, the positioning rod 5 is a screw rod, and a limiting nut 51 cooperating with the positioning rod 5 is arranged above the upper shell 2 to limit the maximum vibration height of the upper shell 2.

[0031] Furthermore, the upper shell 2 is a cover structure that opens downward, and the lower shell 3 is a cover structure that opens upward and is sleeved inside the upper shell 2. The two are preferably clearance-matched to form a more stable sliding connection.

[0032] The working process of the utility model is as follows: when the vibration reduction assembly 4 needs to be replaced, first support the vibration isolation stand 10 with a claw jack, then unlock the positioning rod 5 through the limit nut 51, so that the vibration reduction assembly 4 no longer has a natural state of supporting force, and remove the detachable structure 21 on the side of the upper shell 2. In this process, adjust the jack to form a large enough gap between the upper shell 2 and the lower shell 3 for the vibration reduction assembly 4 to be taken out, and then pull the positioning rod 5 through the through hole 22 to take out the vibration reduction assembly 4 from the side. Finally, install the newly processed vibration reduction assembly 4 in place, loosen the positioning rod 5, restore the vibration reduction assembly 4 to a normal working state, and after checking that it is correct, tighten the side detachable structure 21 with bolts. Finally, loosen the claw jack, and the equipment can operate normally.

[0033] The advantage of this structure is that the vibration reduction assembly 4 can be replaced in a very short time without dismantling equipment, pipes, and joints, etc., which can not only save a lot of manpower and material resources, but also save considerable costs. More importantly, this replacement method basically does not involve the original overall vibration isolation system, there is no subsequent re-debugging problem, and the impact on the operating conditions of the equipment is minimal.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as the protection scope of the present invention.
