Referring to fig. 1-3, fig. 1-3 show a tower head structure according to an embodiment of the present invention, in which the embodiment provides a tower head 200, the tower head 200 includes a support 210, a connector 220, and four connecting chords 230;

one end of each of the four connecting chords 230 is connected with the support 210, and the connection positions of the four connecting chords 230 and the support 210 are distributed around one end of the support 210 facing the connector 220; the other ends of the four connecting chords 230 are connected to the connecting head 220, and the four connecting chords 230 extend in a direction away from the support 210 and are inclined toward a side close to the center of the support 210.

The working principle of the tower head 200 is as follows:

the tower head 200 includes a support 210, a connecting head 220, and four connecting chords 230. One end of each of the four connecting chords 230 is connected to the support 210, and the other end of each of the four connecting chords 230 is connected to the connector 220; when the connecting chords 230 are provided, the four connecting chords 230 are each inclined toward the center of the support 210. Therefore, the four connecting chords 230 are gradually close to one end of the connecting head 220 from one end of the support 210, and the structure of the tower head 200 is simplified while the stress stability of the tower head 200 is ensured through the arrangement mode, so that the weight of the tower head 200 is reduced, and the tower head 200 is convenient to use.

It should be noted that, firstly, since the four connecting chords 230 gradually approach from one end of the support 210 to one end of the connecting head 220, the profile of the tower head 200 is tapered, the bottom of the taper is the support 210, and the top is the connecting head 220; in addition, in this way, along the direction from the connector 220 to the support 210, the projection of the connector 220 on the support 210 is relatively located at the center of the support 210, and the connection positions of the four connecting chords 230 and the support 210 are located around one end of the support 210 facing the connector 220, so that, when the connector 220 is in a stressed state, the stress applied to the connector is transmitted to the support 210 through the four connecting chords 230 in a balanced manner, and the stress stability of the tower head 200 in the use process can be ensured.

Further, referring to fig. 1-3, in the present embodiment, when the four connecting chords 230 are installed, in order to enable the four connecting chords 230 to be connected to the support 210 on the premise that the four connecting chords 230 are inclined toward the center of the support 210, the tower head 200 further includes four connecting ear plates 240, and the four connecting ear plates 240 are respectively located at the connecting positions of the four connecting chords 230 and the support 210. That is, in the present embodiment, it is adopted that the connecting lug 240 is provided so that the connecting chord 230 inclined toward the center of the holder 210 with respect to the holder 210 can be connected to the holder 210;

similarly, in other embodiments of the present invention, in order to facilitate the connection between the connector 220 and the four connecting chords 230, a connecting ear plate 240 may be disposed at the connection between the connector 220 and the connecting chords 230.

Specifically, in the present embodiment, the connecting ear plate 240 includes a first part 241 and a second part 242 connected to the first part 241; the first branch portion 241 is connected to the support 210, and the second branch portion 242 is inclined toward a side close to the center of the support 210 with respect to the first branch portion 241 and connected to the connecting chord 230 so as to adapt to the inclination angle of the connecting chord 230 through the inclined second branch portion 242 to increase the contact area with the connecting chord 230, thereby improving the stability of the connection.

The second section 242 has an opening 243, and the connecting chord 230 is received in the opening 243 and is welded to the second section 242. Similarly, in order to increase the contact area with the connecting chord 230 in the same principle as the inclination of the second section 242, both side surfaces of the opening 243 are in surface contact with the outer peripheral surface of the connecting chord 230 to improve the stability of the connection, and therefore, the opening 243 is inclined toward the center of the holder 210.

In other embodiments of the present invention, in order to increase the contact area with the connecting chord 230 to improve the connection stability, when the connecting chord 230 is connected to the connecting ear plate 240, the end of the connecting chord 230 used for connecting with the support 210 may be provided with a socket, and the second sub 242 is inserted into the socket; or the end of the connecting chord 230 for connecting with the support 210 is provided with a socket, and the second subsection 242 is provided with an opening, and the socket is inserted into the opening.

The purpose of the angle at which the second section 242 is bent and the angle at which the opening 243 is inclined are to increase the contact area with the connecting chord 230, so that the angle at which the second section 242 is bent and the angle at which the opening 243 is inclined are both adapted to the angle at which the connecting chord 230 is inclined when the second section 242 is bent and the opening 243 is opened.

Further, referring to fig. 1-3, in the present embodiment, in order to improve the connection stability, when the connecting chord 230 is connected to the support 210 and the connector 220, a welding connection manner may be adopted, that is, the first part 241 is welded to the support 210, the second part 242 is welded to the connecting chord 230, and the connecting chord 230 is welded to the connector 220.

In this embodiment, the tower head 200 further includes at least one reinforcing ear plate 250, the reinforcing ear plate 250 is connected to two adjacent connecting chords 230, and the reinforcing ear plate 250 is welded to the connecting chords 230 and is located at one end of the connecting chords 230 close to the connecting head 220, so as to increase the stability of the tower head 200 through the reinforcing ear plate 250.

Referring to fig. 1-4, fig. 4 shows structures of a balance arm support and a crane arm support in an embodiment of the present invention, based on the tower head 200, an embodiment of the present invention provides a flat-top tower crane, which includes a tower body, a balance arm support 110, a balance arm pull rod 120, a crane arm support 130, a crane arm pull rod 140, and the tower head 200;
