Description

Technical Field

[0001] The utility model relates to the technical field of coupling disassembly, in particular to a clamping mechanism and a coupling disassembly device. Background Art

[0002] The coupling of the hoisting motor of the bridge gantry crane is generally installed with preload, that is, the installation clearance between the shaft and the coupling is a negative value. On-site installation is generally hot installation (after heating the coupling, put it on the shaft). In actual work, the coupling and the shaft are often too tight, or the mating surface is too rough, which makes the coupling difficult to disassemble. It is often time-consuming and labor-intensive, not only delaying the maintenance period, but also easily damaging the mating surface. General traditional maintenance methods: 1. Use a "three-claw" puller. Due to insufficient bearing capacity, it is easy to cause damage to the puller. 2. Use an ordinary "door frame plus jack" for disassembly. Since there is no support on the top, it is unstable during the placement of the disassembly tool and is easy to fall down, affecting work efficiency.

[0003] In response to the problems that may occur when disassembling a traditional door frame with an external jack, a quick-release component that is convenient for clamping couplings of different sizes is added on the original basis, so that the coupling can be quickly installed on the coupling removal device. The fastening component that can fasten the coupling to the coupling removal device and the ability to adjust the position of the jack make it easier for the jack to remove different types of couplings, thereby achieving better work efficiency. Utility Model Content

[0007] The box assembly includes a V-shaped baffle, a side baffle arranged on one side of the V-shaped baffle, a rear baffle arranged on one side of the side baffle, a bottom plate arranged at the bottom of the V-shaped baffle, and a reinforcing rib arranged on the outer surface of the side baffle;

[0008] The box assembly is subjected to a relatively large tensile force, and is made of a high-strength metal with strong deformation resistance, preferably alloy steel.

[0009] The quick-release assembly comprises a base arranged in the box assembly, a connecting shaft arranged inside the base, a fixing claw connected and installed on the outer surface of the connecting shaft, and a torsion spring installed on the outer surface of the connecting shaft.

[0010] Wherein, the base is fixedly connected to the connecting shaft, the fixing claw is movably connected to the connecting shaft, and the inner diameter of the torsion spring is larger than that of the fixing shaft.

[0013] Among them, the setting of the guiding bevel can make the coupling cut in better.

[0014] As a preferred solution of the clamping mechanism of the utility model, wherein: the reinforcing rib is fixedly connected to one end of the V-shaped baffle and one end of the side baffle, the reinforcing rib is also fixedly connected to one end of the side baffle and one end of the rear baffle, and four identical reinforcing ribs are symmetrically arranged on the outer surface of the side baffle.

[0015] As a preferred solution of the clamping mechanism of the utility model, wherein: the torsion spring is installed outside the connecting shaft, and the two ends of the torsion spring are fixedly installed on the fixing claw and the base respectively.

[0016] The elastic force of the torsion spring can enable the base to reset the fixing claw through the connecting shaft.

[0017] As a preferred solution of the clamping mechanism of the utility model, the fastening assembly includes a screw installed in the threaded hole opened in the rear baffle, a fastening claw movably connected to one end of the screw, and a force wrench movably connected to one end of the screw.

[0018] The screw rod and the outer side of the side baffle are provided with two symmetrical threaded holes for threaded cooperation, and the surface of the fastening claw is provided with anti-slip grooves.

[0019] The clamping mechanism of the utility model has the following beneficial effects: the coupling is quickly and conveniently installed on the box body assembly through the quick-install assembly, and then the coupling is more firmly fixed on the box body assembly through the fastening of the fastening assembly, which solves the problem of the coupling easily falling off during the placement process.

[0020] In actual use, there is still a problem that the jack cannot be moved and couplings of different sizes and types cannot be disassembled.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention.

[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0038] Example 1

[0039] Reference Figures 1 to 3 , which is the first embodiment of the utility model, and this embodiment provides a clamping mechanism

[0040] Specifically, the clamping unit 100 includes a box body assembly 101 , a quick-install assembly 102 disposed inside the box body assembly 101 , and a fastening assembly 103 disposed inside the box body assembly 101 .

[0041] The box assembly 101 includes a V-shaped baffle 101a, a side baffle 101b arranged on one side of the V-shaped baffle 101a, a rear baffle 101c arranged on one side of the side baffle 101b, a bottom plate 101d arranged at the bottom of the V-shaped baffle 101a, and a reinforcing rib 101e arranged on the outer surface of the side baffle 101b.

[0042] The box assembly 101 will be subjected to a relatively large tensile force, and its material is a high-strength metal with strong deformation resistance, preferably alloy steel.

[0043] The quick-release assembly 102 includes a base 102a disposed in the box assembly 101, a connecting shaft 102b disposed inside the base 102a, a fixing claw 102c connected to and installed on the outer surface of the connecting shaft 102b, and a torsion spring 102d installed on the outer surface of the connecting shaft 102b.

[0044] The base 102a is fixedly connected to the connecting shaft 102b, the fixing claw 102c is movably connected to the connecting shaft 102b, and the inner diameter of the torsion spring 102d is larger than that of the fixing shaft 102b.

[0045] Furthermore, two symmetrical threaded holes are formed on the outer side of the side baffle 101b, and a through hole is formed on the surface of the rear baffle 101c.

[0046] The quick-install assembly 102 further includes a guide bevel 102c - 2 formed on the fixing claw 102c and a boss 102c - 1 formed on the outer surface of the fixing claw 102c .

[0047] Preferably, the setting of the guiding bevel 102c-2 can enable the coupling G to cut in better.

[0048] Furthermore, the reinforcing rib 101e is fixedly connected to one end of the V-shaped baffle 101a and one end of the side baffle 101b. The reinforcing rib 101e is also fixedly connected to one end of the side baffle 101b and one end of the rear baffle 101c, and four identical reinforcing ribs 101e are symmetrically arranged on the outer surface of the side baffle 101b.

[0049] It should be noted that the torsion spring 102d is installed outside the connecting shaft 102b, and two ends of the torsion spring 102d are fixedly installed on the fixing claw 102c and the base 102a respectively.

[0050] The elastic force of the torsion spring 102d can enable the base 102a to reset the fixing claw 102c through the connecting shaft 102b.

[0051] In summary, when in use, move the coupling G to the fixed claw 102c. At this time, press down the coupling G, and the coupling will move to the boss 102c-1 through the guide bevel 102c-2 on the fixed claw 102c. Under the action of the torsion spring 102d, the fixed claw 102c will clamp the coupling G, thereby completing the rapid tightening of the coupling G.

[0052] Example 2

[0053] Reference Figure 1 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a fastening assembly 103.

[0054] Specifically, the fastening assembly 103 includes a screw rod 103a installed in a threaded hole provided in the rear baffle 101c, a fastening claw 103b movably connected to one end of the screw rod 103a, and a force wrench 103c movably connected to one end of the screw rod 103a.

[0055] The screw rod 103a and the side baffle plate 101b are provided with two symmetrical threaded holes for threaded cooperation, and the surface of the fastening claw 103b is provided with anti-slip grooves.

[0056] In summary, when in use, after the coupling is quickly clamped by the quick-release assembly 102, the screw 103a is moved forward by rotating the force wrench 103c, driving the fastening claws 103b to fit against the outer surface of the coupling. At this time, when both fastening claws 103b are fitted to the outer surface of the coupling, the coupling is locked by the force wrench 103c to complete the tightening of the coupling.

[0057] Example 3

[0058] Reference Figures 1 to 5 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a coupling disassembly device.

[0059] Specifically, the coupling disassembly device includes a distance adjustment assembly 201 arranged inside the box assembly 101 , and a jack 202 arranged inside the box assembly 101 .

[0060] Furthermore, the distance adjustment component 201 includes a guide groove 201a opened in the base plate 101d, a transmission rod 201b installed in a through hole opened in the base plate 101d, a limit ring 201c fixedly connected to the surface of the transmission rod 201b, a fixed sleeve 201d installed at one end of the limit ring 201c, and a handwheel 201e set at one end of the transmission rod 201b.

[0061] Among them, the fixed sleeve 201d is interference fit with the through hole opened on the surface of the rear baffle 101c. The fixed sleeve 201d will not clamp the limit ring 201c when it is installed in place. The inner diameter of the fixed sleeve 201d is larger than the outer diameter of the transmission rod 201b, and the inner diameter of the fixed sleeve 201d will not be reduced due to the interference fit of the fixed sleeve 201d, causing the transmission rod 201b to be unable to rotate.

[0062] More preferably, a slider 202a is fixedly connected to the bottom of the jack 202.

[0063] A threaded hole is provided in the slider 202a, which can be threadedly matched with the transmission rod 201b. The jack 202 can slide up and down in the box assembly 101 through the slider 202a.

[0064] It should be noted that the guide groove 201a and the V-shaped baffle 101a are located at the same center line, so the jack 202 is also located at the same center line as the V-shaped baffle 101a.

[0065] In summary, when in use, the coupling is quickly clamped by the quick-release assembly 102, and then the coupling G is tightened by the tightening assembly. At this time, the hand wheel 201e is turned to rotate the transmission rod 201b, driving the sliding block 202a matched therewith to move. Because the outer surface of the transmission rod 201b is provided with a fixedly connected limit ring 201c, and it is fixed by the fixing sleeve 201d, turning the hand wheel 201e will only rotate the transmission rod 201b, and will not cause the transmission rod 201b to move forward and backward. Block 202a is fixedly connected, so the jack 202 can be moved by turning the hand wheel 201e, and the jack 202 can be moved to the center position of couplings G of different sizes, or to the shaft wall position of the hollow shaft. At this time, the jack 202 continuously applies pressure to push the end face of the shaft body of the coupling G. The coupling G is installed on the V-shaped baffle 101a, which will generate a reaction force with the jack 202 installed on the rear baffle 101c, so that the shaft body is separated from the flange, completing the disassembly of the coupling.

[0067] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.
