Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical technical field, concretely relates to a kind of auxiliary tools for cooperating with puller to pull out slope structure coupling. BACKGROUND

[0002] At present, the coupling of many high-voltage motors adopts a slope thickening reinforcing structure. When the motor is overhauled, the paw of the puller will slip when the operator uses the puller to pull out the slope structure coupling. It is very laborious to pull out the slope structure coupling, and the number of operations is too much. The puller and the coupling are in direct contact, and long-term operation causes the surface of the coupling to be scratched and rusted. After the scratch expands into a crack, stress concentration will occur, which will reduce the service life of the coupling and even affect the use of other machinery, causing safety hazards.

[0003] Therefore, in order to solve the problem of difficulty and slipping when using the puller to pull out the slope structure coupling, and prevent potential safety risks, an auxiliary tool for cooperating with the puller to pull out the slope structure coupling is needed to prevent slipping when using the puller, and to easily and conveniently assist the operator to quickly and safely pull out the slope structure coupling without damaging the slope structure coupling. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims to provide an auxiliary tool for cooperating with the puller to pull out the slope structure coupling to solve the problem of slipping and easy damage of the puller when pulling out the slope structure coupling in the prior art.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0006] An auxiliary tool for cooperating with the puller to pull out the slope structure coupling includes a circular fastening collar. The upper end surface of the fastening collar is provided with a gripping block for fitting the coupling slope. The length of the gripping block is less than the length of the fastening collar. The side of the gripping block facing the center of the fastening collar is a bevel. The lower end surface of the fastening collar is a flat surface or a concave surface. The fastening collar is composed of two connecting sleeve blocks, which are detachably connected.

[0007] The principle and advantages of the present solution are as follows:

[0008] In practical application, the puller is generally used to pull the coupling, but for the coupling with slope structure, the puller cannot firmly hold the coupling with slope structure because there is no force point, so it is difficult to pull the coupling with slope structure. The present application provides a flat surface that matches the slope structure to serve as the force point for pulling the coupling with slope structure. Specifically, two connecting sleeve blocks are buckled on the coupling with slope structure and fixed, and the clamping blocks arranged on the connecting sleeve blocks can tightly match the slope surface of the coupling with slope structure. In consideration of the convenience of processing and the strength, the ends of the connecting sleeve blocks are left for fixing. The lower surface of the connecting sleeve block of the device of the present application replaces the slope surface of the coupling with slope structure to become the stable force point of the puller. The lower surface of the connecting sleeve block is flat or concave, which can make the puller hold more firmly and stably, and the effect is better, solving the problem of slipping of the puller when pulling the coupling with slope structure.

[0009] Preferably, as an improvement, the inclined surface of the clamping block is provided with a tooth-shaped rubber pad.

[0010] In order to prevent scratches caused by friction between metals, a tooth-shaped rubber pad is arranged on the tooth block, which can avoid wear caused by direct contact and friction between metals, and also increase the friction to make the matching more closely.

[0011] Preferably, as an improvement, the overall material of the fastening sleeve ring and the clamping block is rust-proof metal.

[0012] The rust-proof material helps to improve the service life and reduce the loss, and has sufficient strength and rigidity to withstand the force of the puller and is not easy to be damaged.

[0013] Preferably, as an improvement, the two ends of the two connecting sleeve blocks are provided with screw holes that coincide with each other, and the screw holes are threadedly connected with bolts.

[0014] In consideration of the convenience of use, the way of arranging screw holes at the two ends to connect the bolts is very firm and reliable, and the disassembly is also relatively simple.

[0015] Preferably, as an improvement, the two ends of the two connecting sleeve blocks are provided with connecting holes that coincide with each other, one end of the two connecting sleeve blocks is rotatably connected, and the other end of the two connecting sleeve blocks is detachably connected.

[0016] In the use process, although the traditional bolt and nut are very stable, but in the process of assisting in pulling the coupling with slope structure, only the fastening sleeve ring needs to be temporarily fixed, and the bolt and nut are very troublesome to fix, increasing unnecessary workload, therefore, the form of one end rotating connection and the other end pin connection is adopted, which is simple and fast in operation, and can also ensure stability.

[0017] Preferably, as an improvement, the holding blocks are triangular blocks arranged equidistantly along the circumference of the fastening ring, and the top of the triangular blocks is a planar structure.

[0018] Under the premise of ensuring strength, the whole holding block is divided to form triangular blocks arranged equidistantly, which is beneficial to reduce the quality and save the material cost, the top of the triangular blocks is a planar structure to enhance safety and prevent scratching the operator.

[0026] The following is further explained in detail through specific embodiments:

[0027] The reference signs in the drawings of the specification include: drawbar 1, slope structure coupling 2, fastening ring 3, shaft body 4, draw claw 101, rotating rod 102, upper connecting sleeve block 301, lower connecting sleeve block 302, holding block 303, rubber pad 304, connecting hole 305, pin 306, threaded hole 307, bolt 308, nut 309, recess 310.

[0028] The embodiment one is basically as shown in the drawings: Figures 1-5

[0029] As shown in the drawings, Figure 1 , 2 ​​As shown, an auxiliary tool for matching the puller to pull the slope structure coupling, including a circular fastening ring 3, the upper end surface of the fastening ring 3 is provided with a clamping block 303 for fitting the slope surface of the coupling, the clamping block 303 is a triangular block body arranged at equal intervals along the circumference of the fastening ring 3, the top of the triangular block body is a plane structure, the equal interval arrangement of the clamping block 303 can uniformly bear the force, and the plane structure enhances the safety and prevents scratching the operator. The side of the clamping block 303 facing the center of the fastening ring 3 is a bevel, which can better fit the slope surface of the coupling.

[0030] The bevel of the clamping block is provided with a tooth-shaped rubber pad to avoid wear caused by direct metal contact and friction, and to increase the friction force. The overall material of the fastening ring and the clamping block is rust-proof metal, which is not easy to damage and enhances its service life.

[0031] The lower end surface of the fastening ring is a plane or an inner concave surface, and in this embodiment, the lower end surface of the fastening ring 3 is an inner concave surface provided with a groove 310, which further enhances the force point of the puller 1 and prevents the puller 1 from slipping during pulling. The fastening ring is composed of two connecting sleeve blocks, which are detachably connected between the two connecting sleeve blocks,

[0032] As shown in the accompanying Figure 1 , one end of the two connecting sleeve blocks is connected by a pin shaft, and the other end is connected by a pin 306. In this way, during installation, only the free end of the connecting sleeve block needs to be connected by the pin 306. Because the puller is a short-term operation, the detachable connection is convenient for operation. For areas that need frequent operation, the structure of the auxiliary tool is that one end is rotatably connected and the other end is detachably connected by a pin. After pulling out one slope structure coupling, the other slope structure coupling is pulled out by detaching it, which is very convenient.

[0033] The specific implementation is as follows:

[0034] As shown in the accompanying Figure 3 , the slope structure coupling 2 is pulled out from the shaft body 4 using the puller 1, the pin 306 on one side of the fastening ring 3 is opened, the upper connecting sleeve block 301 and the lower connecting sleeve block 302 are rotated and separated, the position is adjusted, the tooth-shaped rubber pad 304 on the slope surface of the clamping block 303 is tightly attached to the slope surface of the slope structure coupling 2, the upper connecting sleeve block 301 and the lower connecting sleeve block 302 are rotated and closed, the connecting hole 305 is aligned, the pin 306 is inserted and fixed, and the fastening ring 3 is fixed at the lower end of the slope structure coupling 2. As shown in the accompanying Figure 4As shown, the puller 1's claw 101 is opened, so that the claw 101 is engaged in the groove 310 on the lower surface of the fastening collar 3. At this time, the lower surface of the fastening collar 3 replaces the original slope surface of the inclined coupling 2 to bear the force, and the puller 1 has a reliable and stable point of force. The lower end of the puller 1's screw rod 102 abuts against the shaft 4. By rotating the handle on the screw rod 102, the claw 101 firmly grips the groove 310 on the lower surface of the fastening collar 3, and then moves upward to pull out the inclined coupling.

[0035] This solution solves the problem of slippage of the claws when using puller 1 to remove the sloping coupling 2, and can easily and conveniently assist operators in quickly and safely removing the sloping coupling using puller 1 without damaging the coupling.

[0036] Example 2 is attached. Figure 6 As shown:

[0037] The difference from Example 1 is that: Figure 1 As shown, both connecting sleeves have overlapping threaded holes 307 at their ends, and bolts 308 are threaded into the threaded holes 310. Both ends of the two connecting sleeves are connected by bolt threads. The bolt connection also provides a self-locking effect, preventing the locking element from falling off during pulling. For couplings requiring high operational stability and subjected to very large forces, the bolt connection method can be used to provide stronger stress stability.

[0038] The specific implementation method differs from Embodiment 1 in the connection operation steps of the two connecting sleeves: the upper connecting sleeve 301 and the lower connecting sleeve 302 are clamped on the lower end of the slope of the slope structure coupling, the screw holes 307 are aligned, the bolts 308 are inserted, and the nuts 309 are tightened to fix them, so that the fastening collar 3 is fixed at the lower end of the slope structure coupling 2.

[0039] The parts of the specific implementation method that are the same as those in Example 1 will not be repeated here.

[0040] Example 3 is attached. Figure 7 As shown:

[0041] The difference from Embodiment 1 and Embodiment 2 is as follows: Figure 7 As shown, the clamping block 303 is a semi-circular ring, the length of which is less than the length of the fastening collar 3. The ends of the two connecting sleeves are connected by bolts or pins. The specific implementation method is the same as that in Embodiments 1 and 2, and will not be repeated here.

[0042] The above only is the embodiment of the present application, and the well-known specific technical solutions and / or common knowledge in the scheme are not described in detail. It should be pointed out that, for those skilled in the art, without departing from the technical solutions of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope claimed in the present application should be subject to the content of its claims, and the specific implementation mode and the like recorded in the specification can be used to explain the content of the claims.
