Technical Field

The invention relates to the technical field of winches, in particular to a combined disc for connecting a winch and a winch device.

background

The crane usually rotates by the hoist engine to drive the steel wire rope to carry heavy objects, and the hoist engine is usually installed on the hoist engine frame to be fixed, thereby ensuring that the hoist engine rotates under the work of large load, and the frame is the basic guarantee for ensuring the normal work of the hoist engine.

generally, a crane is provided with a winch and a frame, and is a frame with a customized measuring body. As shown in fig. 1, the frame 10 is installed with an adapted winch (referred to as an original winch 20 herein), a first connecting portion 201 of one end of the original winch 20 is connected with the first frame connecting portion 101 of the frame 10 by a bolt, and a second connecting portion 202 of the other end is connected with the second frame connecting portion 102 of the frame 10 by a bolt.

However, if the original hoist 20 is replaced with another hoist 30, a new hoisting mechanism is formed, and since the connection size of both ends of the other hoist 30 is different from that of the original hoist 20, it cannot be installed to be fitted to the frame 10. At present, as shown in fig. 2, it is common practice to connect a first hoisting connection portion 301 at one end of the hoisting machine 30 and a first frame connection portion 101 of the frame 10 in a fitting manner, and weld a flange bracket 103 at a position of the frame 10 where a second hoisting connection portion 302 of the hoisting machine 30 is connected, so that the second hoisting connection portion 302 of the hoisting machine 30 is fixed on the flange bracket.

However, this would change the original frame structure, which would be less likely if the original winch 20 were replaced, i.e., one frame could not be used for multiple winches.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.

The invention provides a combination tray for connecting a winch, which comprises a first annular tray body 1 and a second annular tray body 2 which can be fixedly connected with the first annular tray body 1 concentrically, wherein the first annular tray body 1 is provided with a plurality of first bolt holes 11 for connecting with a frame 10, namely the size phi B of the circumference of the first bolt holes 11 is suitable for connecting with the frame 10, and the second annular tray body 2 is provided with a plurality of second bolt holes 21 for connecting with a winch 30, namely the size phi C of the circumference of the second bolt holes 21 is suitable for connecting with the winch 30.

The combination disk provided by the invention can enable the frame 10 which can only be connected with the original winch 20 (as shown in figure 1) to be connected with another type of winch 30 through the combination disk. As shown in fig. 5-8, the structure for connecting the winch 30 by the combined disk provided by the present invention is that first, the second annular disk 2 is fixed on the winch 30 by the first bolt 3, then the first annular disk 1 is fixed on the second annular disk 2, for example, the first annular disk 1 and the frame 10 are fixed together by the second bolt 4, and then the first annular disk 1 and the frame 10 are connected by the third bolt 5, so that the installation of the winch 30 on the frame 10 can be realized. The combined disk not only performs size conversion on the bolt hole of the winch 30 used for connecting the frame 10 in the radial direction, so that the winch 30 can be butted with the frame 10 through the bolt hole of the combined disk, but also compensates the axial distance between the winch 30 and the frame through the thickness of the combined disk, so that the length of the winch 30 can be suitable for the frame 10.

Therefore, the present invention provides a technical solution that the hoist 30, which is not suitable for being connected with the frame 10, can be connected to the frame 10 by transferring the combination tray. In this way, different types of winches can share one frame without damaging the structure and the function effect of the frame, so that the winch 30 can be simply replaced to the original winch 20 to be installed on the frame 10, and the winch is simple in structure and easy to install.

in a preferred embodiment of the present invention, the first annular disk 1 and the second annular disk 2 are fixed together by bolts.

As shown in fig. 3, a first connection hole 12 is formed in the first annular tray 1, a second connection hole 22 corresponding to the first connection hole 12 is formed in the second annular tray 2, and the first annular tray 1 and the second annular tray 2 can be fixed together by bolts passing through the first connection hole 12 and the second connection hole 22.

Of course, it will be understood by those skilled in the art that the first annular disc 1 and the second annular disc 2 may be fixed together by other means such as clamping. Of course, the preferred manner of fastening is when bolting.

Preferably, the first connection hole 12 is disposed radially outward of the first bolt hole 11, and the second connection hole 22 is disposed radially outward of the second bolt hole 21. It is understood that the first connection holes 12 and the second connection holes 22 may be arranged alternately with the bolt holes of the disk body in the circumferential direction, or may be arranged radially inside the bolt holes of the disk body, which is not limited herein.

When the combined disk is installed, the second annular disk body 2 is firstly fixed on the winch 30 through the first bolt 3, then the first annular disk body 1 is fixed on the second annular disk body 2, and then the first annular disk body 1 is connected to the rack 10. Since the first bolts 3 pass through the second annular disc body 2 from the side of the second annular disc body 2 facing the first annular disc body 1, in order to prevent the bolt heads of the first bolts 3 from affecting the fit between the first annular disc body 1 and the second annular disc body 2, it is preferable that the second bolt holes 21 of the second annular disc body 2 include a sinking groove 211 for accommodating the bolt heads, the sinking groove 211 being on the side of the second annular disc body 2 facing the first annular disc body 1, whereby the bolt heads of the first bolts 3 can be accommodated in the sinking groove 211, so that the first annular disc body 1 and the second annular disc body 2 can be attached together.

in addition, a fitting structure that fits the first annular disk 1 and the second annular disk 2 to each other is provided between the first annular disk 1 and the second annular disk 2.

Preferably, the matching structure includes a first annular protrusion 23 formed on one side of one of the first annular disk 1 and the second annular disk 2 and a ring groove structure 13 formed on one side of the other facing the first annular protrusion 23 to match with the first annular protrusion 23.

In the present embodiment, the first annular projection 23 is formed on the side of the second annular disk 2 facing the first annular disk 1, and the second bolt hole 21 passes through the first annular projection 23. The thickness of the portion where the second bolt hole 21 is provided can be made sufficient to provide the countersunk groove 211 by providing the second bolt hole 21 through the first annular protrusion 23.

In addition, a side of the first annular disk 1 facing away from the second annular disk 2 is formed with a second annular projection 14 at a position close to the inner ring. The second annular protrusion 14 is adapted to cooperate with a structure of the housing 10. As shown in fig. 7 and 8, a second frame connecting portion 102 for connecting with one end (right end in fig. 7) of the winding machine 30 is provided on the frame 10, and the second annular protrusion 14 extends into a central hole of the second frame connecting portion 102 and is engaged with an inner wall of the central hole, thereby facilitating a stable connection of the combination tray and the frame 10.

In the technical scheme provided by the invention, a plurality of second annular disc bodies 2 can be arranged, and the second bolt holes 21 of the plurality of second annular disc bodies 2 are suitable for being connected with different winches. That is, the first annular disks 1 may be respectively connected with the second annular disks 2 having different second bolt holes 21. When different winches are connected, a second annular disc body 2 suitable for the winches can be selected to be connected to the winches, and the same first annular disc body 1 can be adopted to be connected to the second annular disc body 2 in a matching mode.

The following describes in detail the process of connecting the hoist 30 to the frame 10 by using the combination tray according to the present invention with reference to fig. 5 to 8:

In this embodiment, the first hoisting connection part 301 at the left end of the hoisting machine 30 is adapted to the first frame connection part 101 of the frame 10, and the transfer of the combination tray is not required, so that the first hoisting connection part 301 at the left end of the hoisting machine 30 can be directly fixed on the first frame connection part 101 of the frame 10 by bolts. Of course, if the first reel connecting part 301 is not matched with the first rack connecting part 101, a combination tray may be used for the transfer connection.

The second winch connecting part 302 at the right end of the winch 30 is not adapted to the second frame connecting part 102 of the frame 10, so that the transfer is performed by the combination tray provided by the present invention. Specifically, the method comprises the following steps:

First, the second annular disc body 2 adapted to the hoisting machine 30 is selected, that is, the dimension Φ C of the circumference where the second bolt holes 21 of the second annular disc body 2 are located is adapted to the hoisting machine 30, and the combined thickness of the first annular disc body 1 and the second annular disc body 2 can compensate the distance between the hoisting machine 30 and the frame 10.

A second annular disc body 2 is connected to a second hoisting connection part 302 at the right end of the hoisting machine 30 through a first bolt 3 (as shown in fig. 5);

Connecting the first annular disc body 1 to the second annular disc body 2 through a second bolt 4 (as shown in fig. 6);

the first annular disk 1 is attached to the second frame attachment portion 102 of the frame 10 by the third bolt 5 (as shown in fig. 7 and 8).

Whereby the connection of the hoist 30 to the frame 10 is accomplished.

If the original winch 20 needs to be replaced, the winch 30 and the combined disk are disassembled, and the original winch 20 is directly installed on the rack 10;

If another hoist different from the original hoist 20 and hoist 30 is to be connected to the frame 10, the second annular plate 2 adapted to the another hoist is selected to be coupled to the frame 10 in cooperation with the first annular plate 1.

According to another aspect of the present invention, there is also provided a winding apparatus comprising a winding machine 30, a frame 10 and the above-mentioned combination tray;

One of the second annular discs 2 is connected with the winch 30, and the first annular disc 1 is connected with the second annular disc 2 and the frame 10.

the specific connection is as described above.

The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Within the scope of the technical idea of the invention, numerous simple modifications can be made to the technical solution of the invention, including combinations of the individual specific technical features in any suitable way. The invention is not described in detail in order to avoid unnecessary repetition. Such simple modifications and combinations should be considered within the scope of the present disclosure as well.
