[0027] The utility model will be described in detail below in combination with the drawings and specific embodiments. It should be noted that similar or identical parts are denoted by the same reference numerals in the drawings or description, and the implementation manners not shown or described in the drawings are known to those skilled in the art. In addition, the directional terms mentioned in the embodiments, such as "up", "down", "top", "bottom", "left", "right", "front", "back", etc., are only with reference to the direction of the drawings and are not intended to limit the scope of protection of the utility model.

[0028] Embodiment 1,

[0029] As Figures 1-5 shown, the embodiment is a second coupling dismounting device for dismounting the second coupling 2 installed between the transmission shaft 1 and the conveying belt input shaft 3; comprising two oppositely arranged support bodies 4, one side of the two oppositely arranged support bodies 4 is hinged and the other side is abutted to form a cylindrical structure, the end face of the cylindrical structure is provided with a relief hole 41 and a bolt hole 42, and the relief hole 41 and the bolt hole 42 are arranged in a circular manner; wherein, in one end face of the cylindrical structure, the relief hole 41 and the bolt hole 42 are arranged in a circular manner, each having three, and in the other end face of the cylindrical structure, the relief hole 41 and the bolt hole 42 are also arranged in a circular manner, each having three; at the same time, the arrangement of the relief hole 41 and the bolt hole 42 in the two end faces is staggered, that is, the relief hole 41 of one end face is staggered with the relief hole 41 of the other end face, and is opposite to the bolt hole 42 of the other end face; vice versa. The end face inner wall of the cylindrical structure is abutted with the shaft shoulder 12 of the transmission shaft 1 or the shaft shoulder of the conveying belt input shaft 3, and the inner surface 48 of the cylindrical structure is attached to the outer surface of the second coupling 2, and the dismounting bolt 45 screwed out of any bolt hole 42 will push the connecting bolt 5 out of the corresponding relief hole 41.

[0030] For example, the shape of the support body 4 is a half-cylindrical shape, and the end face is designed as a semicircle, corresponding to the end face of the thin shaft of the transmission shaft 1 and the end face of the thin shaft of the conveying belt input shaft 3.

[0031] In fact, according to the actual situation, the end face outer wall of the cylindrical structure can also be abutted with the chamfer of the thin shaft of the transmission shaft 1, which has a small abutted area and is easy to tilt. The fixing mode of the end face inner wall of the cylindrical structure abutting with the shaft shoulder 12 of the transmission shaft 1 in the embodiment is not easy to tilt, has a larger contact area, high structural strength, and is easy to operate in the surrounding mode, and has high practicability. Similarly, the fixing mode of the end face inner wall of the cylindrical structure abutting with the shaft shoulder of the conveying belt input shaft 3 is not easy to tilt, has a larger contact area, and has high structural strength.

[0032] For example, the avoidance holes 41 and the bolt holes 42 are arranged in a staggered arrangement around the circumference, depending on the forward and reverse installation method of the connecting bolts 5 connecting the transmission shaft 1, the second coupling 2, and the conveyor belt input shaft 3. For example, one end surface of a support body 4 has one avoidance hole 41 and two bolt holes 42 staggered, while the other end surface has two avoidance holes 41 and one bolt hole 42, and the bolt holes 41 and avoidance holes 42 on both end surfaces are arranged in opposite positions. This structural design is particularly suitable for ejecting the connecting bolts 5 when removing them.

[0033] In fact, according to actual conditions, it is also possible to choose to use the fixing screws 44 for connection. The cylinder structure of this embodiment adopts a one-side hinged method, so fewer fixing screws 44 need to be tightened during enclosure, which saves time.

[0034] In practice, one side of the two opposing supports 4 is hinged and the other side is abutted. Alternatively, one side of the supports 4 may be provided with a hinge, such as a hinge seat 46 or a hinge shaft 47. The end of the hinge shaft 47 is rotatably connected to the hinge seat 46. A fixed structure is provided on the other side of the supports 4 for locking the enclosed cylindrical structure. With this structural design, one side of the supports 4 is fixed by the hinge while remaining rotatable. Fixed installation is achieved through the fixed structure on the other side. Disassembly of all connecting bolts 5 of the second coupling 2 requires only one clamping operation, making installation convenient and highly practical.

[0035] In fact, according to actual conditions, the following selection can be made: the fixing structure includes an ear seat 43 , the ear seat 43 is provided with a fixing screw hole, and the fixing screw hole is used to install a fixing screw 44 .

[0036] In fact, other fixing structures can also be selected according to actual conditions. In this embodiment, the fixing structure includes a clamping joint, which is clamped with a clamping groove provided on the adjacent support body 4. This structural design saves time compared to installing the fixing screw 44 while meeting the fixed locking force.

[0037] The size of the avoidance hole 41 can be selected according to actual conditions. In this embodiment, to ensure the ejection of the connecting bolt 5, the inner diameter of the avoidance hole 41 is larger than the outer diameter of the bolt head of the connecting bolt 5. Specifically, while ensuring the structural strength of the end face of the support body 4, other openings can be provided. For example, the end face of the cylindrical structure can be processed into a honeycomb structure. In this way, the overall weight of the support body 4 can be reduced, and practicality is improved.

[0038] Exemplarily, the connecting bolts 5 connected with the second coupling 2 are six, three of which are installed along the power transmission direction of the transmission shaft, and the other three are installed along the opposite direction, achieving safe and reliable fixing, the number of the avoiding holes 41 is the same as that of the bolt holes 42, and the sum of the number of the avoiding holes 41 and the number of the bolt holes 42 is the same as that of the connecting bolts 5.

[0039] In fact, according to actual conditions, all the connecting bolts 5 connected with the second coupling 2 can also be installed along the same direction, and such design is relatively simple and convenient in terms of dismounting and mounting.

[0040] In order to more widely adapt to different second couplings 2, the inner surface 48 of the cylinder structure can be provided with different inner diameter specifications, for example, provided with a groove, a protrusion or a rib, which is high in practicability.

[0041] In fact, according to actual conditions, other auxiliary structures can also be selected, that is, the inner surface 48 of the cylinder structure is provided with an auxiliary rib 49, the first end flange 11 is fixedly installed at one end of the transmission shaft 1 close to the second coupling 2, the second end flange 31 is fixedly installed at one end of the conveying belt input shaft 3 close to the second coupling 2, and the auxiliary rib 49 abuts against the first end flange 11 or the second end flange 31.

[0042] In the case that the outer diameter dimensions of the first end flange 11 and the second end flange 31 are the same, the shape of the auxiliary rib 49 is consistent, and in the case that the outer diameter dimensions of the first end flange 11 and the second end flange 31 are different, the shape of the auxiliary rib 49 is different. The auxiliary rib 49 can be installed by integral forming, clamping or welding during processing. Such structure design can better adapt to the scene where the outer diameter of the second coupling 2 is different from the outer diameter of the first end flange 11 and the second end flange 31 when the cylinder structure is used to dismount the second coupling 2, that is, the dismounting bolt 45 is aligned with the connecting bolt 5, which is high in practicability.

[0043] In one case of the present embodiment, when the dismounting bolt 45 is aligned with the connecting bolt 5, the cylinder structure can be rotated to observe the alignment in real time. The cylinder structure in the present embodiment is provided with an observation opening penetrating the wall surface, and the outer wall of the cylinder structure is provided with an adjusting part for rotating the cylinder structure to align the dismounting bolt with the connecting bolt. In this way, high positioning accuracy of the cylinder structure is not required, and subsequent adjustment and alignment can be performed.

[0044] Exemplarily, the adjusting part can be a handle or a rod. The present embodiment can more flexibly eject the connecting bolt 5 through cooperation of the adjusting part with the observation opening.

[0045] In fact, according to actual conditions, a plurality of observation openings can be formed at different positions, so that observation is more convenient and practical.

[0046] The use method and principle of the embodiment are as follows:

[0047] When the second coupling 2 needs to be disassembled and replaced, first, all the nuts 6 on the connecting bolts 5 are disassembled, the support body 4 is wrapped outside the second coupling 2, the support body 4 is enclosed into a cylindrical structure, and the fixing screw 44 is tightened to fix the cylindrical structure; during this process, the inner surface 48 of the cylindrical structure is attached to the outer edge of the second coupling 2; the cylindrical structure has the freedom of rotating around the center of the second coupling 2, so that the alignment of the disassembly bolt 45 and the connecting bolt 5 can be adjusted; in addition, different connecting bolts 5 can be sequentially ejected by one disassembly bolt 45, which is practical.

[0048] When the connecting bolt 5 at one end of the transmission shaft 1 is disassembled, the inner end face of the cylindrical structure close to the transmission shaft 1 is in abutment with the shaft shoulder 12 of the transmission shaft 1, and the disassembly bolt 45 is screwed into one end of the cylindrical structure close to the conveyor belt input shaft 3 to eject the connecting bolt 5; similarly, other connecting bolts 5 in the same direction can be sequentially ejected.

[0049] When the connecting bolt 5 at one end of the transmission shaft 1 is disassembled, the inner end face of the cylindrical structure close to the transmission shaft 1 is in abutment with the shaft shoulder 12 of the transmission shaft 1, and the disassembly bolt 45 is screwed into one end of the cylindrical structure close to the conveyor belt input shaft 3 to eject the connecting bolt 5; similarly, other connecting bolts 5 in the same direction can be sequentially ejected.

[0050] In fact, the disassembly of the connecting bolt 5 at one end of the transmission shaft 1 and the connecting bolt 5 at one end of the conveyor belt input shaft 3 can be alternately performed to balance the locking force of the remaining connecting bolts 5 and improve the disassembly stability of the second coupling 2.

[0051] Embodiment 2,

[0052] The embodiment is a second coupling system, which comprises a second coupling 2, a transmission shaft 1 and a conveyor belt input shaft 3 connected in transmission through the second coupling 2, and the second coupling disassembly device in embodiment 1, the second coupling disassembly device is peripherally arranged around the second coupling 2 to disassemble the connecting bolt 5.

[0053] Such a structure design reduces one disassembly step of the bracket on the basis of the existing structure, which can effectively save time; at the same time, the rotational freedom of the cylindrical structure can be reserved to facilitate the adjustment according to the alignment of the connecting bolt 5 and the disassembly bolt 45; in addition, a plurality of connecting bolts 5 can be sequentially ejected by one disassembly bolt 45, which has high structural strength, is convenient to install, and is practical.

[0054] The second coupling dismounting device provided by the utility model is described in detail above. The description of the specific embodiments is only used for helping to understand the method of the utility model and its core idea. It should be pointed out that, for ordinary skilled persons in the technical field, some improvements and modifications can be made to the utility model without departing from the principle of the utility model, and these improvements and modifications also fall within the protection scope of the utility model claim.
