Description

Technical Field

[0001] This utility model relates to the field of crane tower heads, specifically to a crane tower head. Background Technology

[0002] The tower head is one of the key components of a tower crane. As an important part of the tower crane, it mainly undertakes the core role of connecting the boom and the counterweight boom. It is the key hub for realizing the transmission of force between the boom and the counterweight boom, ensuring the overall structural stability of the tower crane and the normal operation of lifting operations.

[0003] The connection between the tower head and the boom is usually achieved by using ear plates and positioning pins. However, the ear plate structure on the tower head is generally quite thin. Although it can play a certain role in bearing load, it is weak in terms of radial support. When dealing with complex lifting conditions or large loads, it is prone to uneven stress, which leads to local stress concentration and has a certain impact on the overall performance and operational safety of the tower crane.

[0004] Therefore, it is necessary to invent a crane tower head to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a crane tower head that, by setting a support plate, a fixing plate and a diagonal brace, can provide radial support for the ear plate, thereby improving the radial bearing capacity of the ear plate and avoiding uneven stress on the ear plate due to complex working conditions, thus solving the problem that the radial pressure can easily cause stress concentration due to the relatively thin ear plate, and ensuring that the tower head can operate stably.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a crane tower head, comprising: A triangular top frame, wherein an ear plate is fixedly connected to the right side wall of the triangular top frame, a pin is fixedly connected to the inner wall of the ear plate, and a diagonal web member and a vertical web member are fixedly connected to the bottom of the triangular top frame; A horizontal web member, wherein a first reinforcing member and a second reinforcing member are fixedly connected to the side wall of the horizontal web member from left to right, and the horizontal web member is fixedly connected to the bottom end of the diagonal web member and the vertical web member; A support assembly, comprising a support plate, a fixing plate fixedly connected to the top end of the support plate, and a diagonal brace fixedly connected to the bottom end of the support plate; A diagonal bracing assembly, comprising a diagonal brace, wherein a connecting plate is fixedly connected to the top end of the diagonal brace and a positioning plate is fixedly connected to the bottom end of the diagonal brace.

[0007] Preferably, a connector is fixedly connected to the end of the horizontal web member away from the vertical web member, a support rod is fixedly connected to the inner wall of the connector, and the end of the support rod away from the connector is fixedly connected to the outer wall of the pin.

[0008] Preferably, the inner wall of the fixing plate has a first through hole, and the inner wall of the inclined brace plate has a second through hole.

[0009] Preferably, the inner wall of the connecting plate has a first bolt hole, and the inner wall of the positioning plate has a second bolt hole.

[0010] Preferably, the angle between the axes of the vertical web member and the horizontal web member is °, and the diagonal web member, the vertical web member, and the horizontal web member together form an isosceles triangle structure.

[0011] Preferably, the fixing plate is fixedly connected to the side wall of the ear plate, the diagonal brace is fixedly connected to the outer wall of the diagonal brace, the connecting plate is fixedly connected to the outer wall of the support plate, and the positioning plate is fixedly connected to the upper surface of the second reinforcing member.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention utilizes a fixed plate at the top of the support plate in conjunction with a diagonal brace at the bottom to provide radial support for the ear plate. This allows the radial pressure on the ear plate to be evenly distributed across the diagonal brace, preventing stress concentration due to uneven force distribution on the ear plate. Consequently, the radial support force of the ear plate is significantly increased, thereby enhancing the stability of the tower head. Furthermore, the diagonal tie rod, in conjunction with the connecting plate and positioning plate, provides radial support to the middle of the support plate, further improving its stability and enabling it to more stably support the ear plate, thus further enhancing the stability of the ear plate.

A diagonal brace 113 is fixedly connected to the bottom of the support plate 111, and the diagonal brace 113 is fixedly connected to the outer wall of the diagonal web member 4. The diagonal brace 113 can provide axial support to the support plate 111, ensuring the axial stability of the support plate 111. like Figure 2 - Figure 4As shown, the inclined tie assembly 12 includes an inclined tie rod 121. A connecting plate 122 is fixedly connected to the top of the inclined tie rod 121. The connecting plate 122 is fixedly connected to the outer wall of the support plate 111. The connecting plate 122 at the top of the inclined tie rod 121 can support the middle position of the support plate 111, thereby improving the radial bearing capacity of the support plate 111 and enabling it to support the ear plate 2 more stably. A positioning plate 123 is fixedly connected to the bottom of the inclined tie rod 121. The positioning plate 123 is fixedly connected to the upper surface of the second reinforcing member 8. The second reinforcing member 8, in conjunction with the positioning plate 123, can provide axial support for the inclined tie rod 121, so that the inclined tie rod 121 can effectively fix the middle position of the support plate 111.

[0018] like Figure 1 - Figure 2 As shown, a connector 9 is fixedly connected to the end of the horizontal web member 6 away from the vertical web member 5.

Then, the diagonal bracing plate 113 is fixed to the outer wall of the diagonal web member 4. At this time, the fixing plate 112 at the top of the support plate 111 can provide radial support to the side wall of the ear plate 2, and the diagonal bracing plate 113 at the bottom of the support plate 111 can provide axial support to the support plate 111. In this way, the radial pressure on the ear plate 2 can be evenly distributed to the diagonal web member 4 through the fixing plate 112, the support plate 111, and the diagonal bracing plate 113. The triangular structure formed by the diagonal web member 4, the vertical web member 5, and the horizontal web member 6 has strong stability, which can provide strong support for the support plate 111 and greatly improve the radial support force of the ear plate 2.

[0022] After the support plate 111 is fixed, bolts are passed through the first bolt hole 124 and the second bolt hole 125 to fix the connecting plate 122 to the outer wall of the support plate 111. Then, the positioning plate 123 is fixed to the top of the second reinforcing member 8. At this time, the connecting plate 122 at the top of the diagonal tie rod 121 can support the middle position of the support plate 111. At the same time, the positioning plate 123 at the bottom of the diagonal tie rod 121 can provide axial support for the diagonal tie rod 121. The diagonal tie rod 121 can be used to position the middle position of the support plate 111, thereby improving the radial bearing capacity of the support plate 111 and enabling it to support the ear plate 2 more stably.
