Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
In one embodiment, referring to fig. 1 and fig. 6, a dismounting device 100 is provided, the dismounting device 100 includes: the contact member 110, the force-receiving member 120 and the connecting member 130. The contact element 110 is used for contacting against one side of the transmission structure. The force-receiving member 120 is spaced from the abutting member 110, the force-receiving member 120 is located on a side of the transmission structure opposite to the abutting member 110, and the force-receiving member 120 is provided with a first threaded hole 1211. The first screw hole 1211 is for screwing the fixing member 500 and allows one end of the fixing member 500 to abut against the output shaft 410 of the driving member 400. The connecting member 130 is connected between the contact member 110 and the force-receiving member 120.
In the dismounting device 100, during the dismounting process of the transmission structure, such as the dismounting of the sprocket 200, the contact element 110 and the force-bearing element 120 are firstly respectively disposed on the opposite sides of the transmission structure; then, the contact element 110 is connected with the force receiving element 120 through the connecting element 130, so that the transmission structure is clamped between the contact element 110 and the force receiving element 120; then, the fixing member 500 is screwed into the first screw hole 1211 such that one end of the fixing member 500 abuts on the output shaft 410; finally, the fixing member 500 is rotated, and the force-receiving member 120 moves away from the output shaft 410 by the reaction force of the threads, so as to drive the transmission structure to be separated from the output shaft 410, thereby completing the dismantling operation of the transmission structure. Because the reaction force of the screw thread is adopted in the disassembly process, the stressed part 120 is ejected out step by step, and the transmission structure is subjected to thrust transmission through the contact part 110, so that the direct application of the acting force on the chain wheel 200 is avoided, the completeness of the transmission structure is protected, the damage of internal parts of the driving part 400 due to impact force is also effectively avoided, the stable and reliable disassembly of the structure is realized, and the safety of the structure maintenance is improved. Meanwhile, the dismounting device 100 uses the first threaded hole 1211 on the force-bearing member 120 to cooperate with the fixing member 500 to complete dismounting, thereby effectively avoiding the need of forming holes on the transmission structure, reducing the number of holes on the transmission structure, and improving the structural strength of the transmission structure.
It should be noted that the contact member 110 has various shapes, such as: the contact element 110 has a block structure, a strip structure, a U-shaped structure, a frame structure, etc. The embodiment is not particularly limited, and only needs to be satisfied that when the force-receiving member 120 is ejected outwards, the contact member 110 can contact against a side surface of the transmission structure, so that the transmission structure is separated from the output shaft 410.
Alternatively, the drive structure is a sprocket, roller, gear, or the like. The driving member 400 is a cylinder, an electric cylinder, a hydraulic cylinder, a motor, a speed reducer, etc.
Optionally, the connection manner of the connection member 130 on the interference member 110 and the force-receiving member 120 is a threaded connection, a bolt connection, a pin connection, a clamping connection, or the like. Meanwhile, the fixing member 500 is also a bolt, a screw, or the like. Wherein, when mounting 500 is the bolt, the accessible is additionally purchased in the dismantlement process, also can directly adopt the bolt of taking off from the transmission structure.
It should be further noted that, during the disassembly process, the transmission structure is located between the contact element 110 and the force-receiving element 120; the contact element 110 is connected with the force-receiving element 120 through the connecting element 130. At this time, the abutting part 110 and the stressed part 120 may or may not clamp the transmission structure under the action of the connecting part 130, and only when the fixing part 500 pushes the stressed part 120 away from the output shaft 410, the stressed part 120 can drive the abutting part 110 to abut against the transmission structure, and push the transmission structure out of the output shaft 410. Of course, the transmission structure is clamped by the contact element 110 and the force-bearing element 120, which is more convenient for the disassembly operation.
Further, referring to fig. 1, the contact element 110 includes an abutting portion 111. The abutting portion 111 is used for abutting against a side surface of the transmission structure, and the abutting portion 111 is connected with the force-bearing member 120 through the connecting member 130. Therefore, the abutting part 110 is composed of more than one abutting part 111, and the abutting part 111 enables the abutting part 110 to better abut against the transmission structure.
It should be noted that, when there is one abutting portion 111, the abutting portion 111 is directly disposed on one side of the transmission structure and extends out of the edge of the transmission structure, and then the abutting portion 111 and the stressed member 120 are connected by the connecting member 130; when there are at least two interference portions 111, the interference portions 111 may be connected to or disconnected from the interference portions 111. When the contact part 111 is connected to the contact part 111, the contact part 110 has two forms: firstly, the opening structure is formed by only sleeving the opening end of the contact element 110 on the output shaft 410 in the dismounting process; and secondly, the closed structure needs to be assembled on site in the disassembly process, and the abutting parts 111 are sequentially connected around the output shaft 410 on one side surface of the transmission structure.
Furthermore, referring to fig. 1, there are at least two interference portions 111. At least two interference parts 111 are connected in sequence and form a through hole. The contact element 110 is used for sleeving the output shaft 410 through the through hole and abutting against one side surface of the transmission structure. Therefore, the contact element 110 of the present embodiment is a closed structure, and in the detaching process, at least two abutting portions 111 are sequentially connected around the output shaft 410, so that the contact element 110 is sleeved on the output shaft 410 through the through hole. The contact force of the contact element 110 formed in this way on the transmission structure is uniformly distributed, and the stress balance of the transmission structure in the disassembly process is ensured, so that the transmission structure is stably and reliably separated from the output shaft 410.
It should be noted that, when there are two interference portions 111, the interference portions 111 are curved or bent, so as to ensure that the two interference portions 111 can be connected to each other and form a through hole.
Optionally, the connection manner between the interference part 111 and the interference part 111 is bolt connection, pin connection, clamping connection, riveting connection, and the like.
In one embodiment, referring to fig. 2 and 4, the interference portion 111 is provided with a first mounting hole 112 and a second mounting hole 113 at an interval. The first mounting holes 112 of two adjacent interference parts 111 respectively penetrate the connecting member 130, and the second mounting holes 113 of two adjacent interference parts 111 also respectively penetrate the connecting member 130. Therefore, the specific connection mode between the interference part 111 and the interference part 111 is as follows: stacking one end of each of the two abutting portions 111 so that the two first mounting holes 112 are opposite to each other; stacking the other end of one interference part 111 and one end of the other interference part 111 together to enable the two second mounting holes 113 to be opposite; then, stacking the rest of the interference parts 111 in a similar stacking manner, so that the interference parts 111 are stacked in sequence; finally, the plurality of connecting members 130 are inserted into the two first mounting holes 112 and the two second mounting holes 113, respectively, so as to complete the sequential connection of all the interference portions 111. In addition, when the assembly of the contact element 110 is completed, the connection between the contact element 110 and the stressed element 120 is also completed, so that the assembly efficiency of the dismounting device is effectively improved, and the dismounting operation of the transmission structure is greatly facilitated.
Further, referring to fig. 1 and fig. 3, at least two third mounting holes 1221 are disposed on the force-receiving member 120. Third mounting hole 1221 and the first mounting hole 112 on two adjacent conflict portions 111 set up relatively respectively, third mounting hole 1221 still sets up relatively respectively with the second mounting hole 113 on two adjacent conflict portions 111, so, in the dismantlement in-process, only need to penetrate third mounting hole 1221 and two first mounting holes 112 and third mounting hole 1221 and two second mounting holes 113 respectively with connecting piece 130, can accomplish the installation of dismounting device 100 on the transmission structure, further promote dismantlement efficiency.
In one embodiment, referring to fig. 3 and 4, the first mounting hole 112 and/or the second mounting hole 113 are kidney-shaped holes. The third installation hole 1221 is a kidney-shaped hole. Therefore, at least one of the first mounting hole 112 and the second mounting hole 113 is designed as a kidney-shaped hole, so that at least one connecting position on the contact 110 can be adjusted, and the area size of the through hole can be changed; meanwhile, the third mounting hole 1221 is designed to be a waist-shaped hole, so that the connection position of the connecting member 130 on the stressed member 120 can be correspondingly adjusted, and the contact member 110 can be suitable for transmission structures of different sizes, thereby effectively improving the application range of the dismounting device 100.
Further, referring to fig. 3 and 4, the first mounting hole 112 and the third mounting hole 1221 are both waist-shaped holes, and the second mounting hole 113 is a conventional circular hole, that is, a part of the contact element 110 is adjustable, and a part of the contact element is not adjustable, so that it is ensured that only one side needs to be moved during the size adjustment process of the contact element 110, and it is avoided that both sides are in a movable state, which makes adjustment difficult. Meanwhile, the extending direction of the third mounting hole 1221 is located between the extending directions of the two first mounting holes 112, and the extending direction of the third mounting hole 1221 and the extending direction of the first mounting hole 112 form an included angle.
It should be noted that, for convenience of understanding the extending direction of the first mounting hole 112 and the extending direction of the third mounting hole 1221, taking fig. 3 and fig. 4 as an example, the extending direction of the first mounting hole 112 is S in fig. 41The direction indicated by any arrow in (1); the third mounting hole 1221 extends in the direction S in fig. 32In the direction of any arrow in (1).
Specifically, referring to fig. 2, the extending direction of the third mounting hole 1221 is set at 45 ° to the extending direction of the first mounting hole 112.
In one embodiment, referring to fig. 3, the force-receiving member 120 includes a main force-receiving portion 121 and at least two connecting portions 122 connected to the main force-receiving portion 121. The first screw hole 1211 is provided in the main force receiving portion 121. The third mounting hole 1221 is provided on the connecting portion 122. When the fixture 500 is screwed into the first screw hole 1211 and rotated, a reaction force of the screw is applied to the main force receiving portion 121; the pushing force against the transmission structure is distributed on the connecting portions 122 around the stress member 120, so that the stress distribution on the stress member 120 is more reasonable, and the transmission structure is ensured to be stably separated from the output shaft 410.
Further, referring to fig. 3, the number of the connecting portions 122 is four. Four connecting portions 122 are provided at intervals on the main force receiving portion 121. Meanwhile, the number of the interference parts 111 is four. The four interference parts 111 are connected in sequence and form a through hole. The connecting position between two adjacent interference parts 111 is connected with the connecting part 122 through a connecting part 130.
Specifically, the main force receiving portion 121 and the connecting portion 122 are of an integrated structure, so that the overall structural strength of the force receiving member 120 is effectively improved.
In one embodiment, referring to fig. 4 and 5, a first concave portion 114 and a second concave portion 115 are disposed on the interference portion 111 at an interval. The first mounting hole 112 is provided on the first recess 114. The second mounting holes 113 are disposed on the second concave portion 115, so that the first concave portion 114 and the second concave portion 115 are disposed on the abutting portion 111 at intervals, and the surface height of the abutting portion 111 is reduced, so that when two first mounting holes 112 or two second mounting holes 113 are stacked together, the surface of the formed abutting member 110 is flat, and the abutting member 110 stably abuts against the transmission structure.
In one embodiment, referring to fig. 3, the force-bearing member 120 is provided with a notch 123, so that the dismounting device 100 is light and the load of the operator during the dismounting process is reduced.
In one embodiment, referring to fig. 1 and fig. 6, a sprocket 200 dismounting system includes a driving member 400, a sprocket 200, a pressing plate 300 and the dismounting device 100 of any of the above embodiments. The sprocket 200 is sleeved on the output shaft 410 of the driving member 400. The pressing plate 300 is connected to the sprocket 200 and the output shaft 410 by a fixing member 500, respectively. The dismounting device 100 is used to remove the sprocket 200 from the output shaft 410.
In the above-mentioned system for disassembling the sprocket 200, with the above-mentioned disassembling device 100, during the disassembling process of the sprocket 200, the contact member 110 and the force-receiving member 120 are respectively disposed on the two opposite sides of the sprocket 200; then, the contact element 110 is connected with the force-receiving element 120 through the connecting element 130, so that the chain wheel 200 is clamped between the contact element 110 and the force-receiving element 120; then, the fixing member 500 is screwed into the first screw hole 1211 such that one end of the fixing member 500 abuts on the output shaft 410; finally, the fixing member 500 is rotated, and the force receiving member 120 is moved away from the output shaft 410 by the reaction force of the screw threads, so as to drive the sprocket 200 to be separated from the output shaft 410, thereby completing the disassembling operation of the sprocket 200. Because the reaction force of the screw thread is adopted in the disassembly process, the stressed part 120 is ejected out step by step, and the thrust is transmitted to the chain wheel 200 through the contact part 110, so that the direct application of the acting force to the chain wheel 200 is avoided, the structural integrity of the chain wheel 200 is protected, the damage of internal parts of the driving part 400 due to impact force is also effectively avoided, the stable and reliable disassembly of the structure is realized, and the safety of structural maintenance is improved. Meanwhile, the dismounting device 100 uses the first threaded hole 1211 on the force-bearing member 120 to cooperate with the fixing member 500 to complete dismounting, thereby effectively avoiding the need to form holes on the sprocket 200, reducing the number of holes on the sprocket 200, and improving the structural strength of the sprocket 200.

When the process holes 310 are not formed in the pressing plate 300, the structural integrity of the sprocket 200 is ensured, which is beneficial to improving the structural strength of the sprocket 200. Referring to fig. 6 and 7, the process holes 310 are threaded holes, and bolts are screwed so that the bolts abut against the output shaft 410, thereby ejecting the pressing plate 300 and the sprocket 200 together.
Further, referring to fig. 6, a second screw hole 210 is formed in the sprocket 200, a third screw hole 411 is formed in the output shaft 410, and the fixing member 500 is respectively inserted into the second screw hole 210 and the third screw hole 411, so that the pressing plate 300 is stably mounted on the sprocket 200 and the output shaft 410.
In one embodiment, referring to fig. 1, 6 and 9, a method of disassembling a sprocket 200 using the sprocket 200 disassembling system of the previous embodiment comprises the steps of:
s10, removing the fixing piece 500, and taking the pressure plate 300 out of the chain wheel 200 and the output shaft 410;
s20, respectively placing the contact part 110 and the force-bearing part 120 on two opposite sides of the chain wheel 200;
s30, connecting the contact element 110 and the force-receiving element 120 through the connecting element 130, and abutting the contact element 110 against a side surface of the sprocket 200;
S40, screwing the fixing member 500 into the first screw hole 1211, and abutting one end of the fixing member 500 against the output shaft 410;
s50, the fixing member 500 is rotated to take out the sprocket 200 from the output shaft 410.
In the above method for disassembling the sprocket 200, with the above disassembling device 100, during the disassembling process of the sprocket 200, the contact member 110 and the force-receiving member 120 are respectively disposed on two opposite sides of the sprocket 200; then, the contact element 110 is connected with the force-receiving element 120 through the connecting element 130, so that the chain wheel 200 is clamped between the contact element 110 and the force-receiving element 120; then, the fixing member 500 is screwed into the first screw hole 1211 such that one end of the fixing member 500 abuts on the output shaft 410; finally, the fixing member 500 is rotated, and the force receiving member 120 is moved away from the output shaft 410 by the reaction force of the screw threads, so as to drive the sprocket 200 to be separated from the output shaft 410, thereby completing the disassembling operation of the sprocket 200. Because the reaction force of the screw thread is adopted in the disassembly process, the stressed part 120 is ejected out step by step, and the thrust is transmitted to the chain wheel 200 through the contact part 110, so that the direct application of the acting force to the chain wheel 200 is avoided, the structural integrity of the chain wheel 200 is protected, the damage of internal parts of the driving part 400 due to impact force is also effectively avoided, the stable and reliable disassembly of the structure is realized, and the safety of structural maintenance is improved. Meanwhile, the dismounting device 100 uses the first threaded hole 1211 on the force-bearing member 120 to cooperate with the fixing member 500 to complete dismounting, thereby effectively avoiding the need to form holes on the sprocket 200, reducing the number of holes on the sprocket 200, and improving the structural strength of the sprocket 200.
