Description

[0001] This application is a divisional application of Chinese Patent Application No. 202311370160.0, entitled "An installation bracket for a standard section of a tower crane", the contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of tower crane standard section installation technology, specifically to a support base structure and installation method for installing tower crane panel standard sections. Background Technology

[0003] Tower cranes are an indispensable lifting equipment in the construction industry, and their tower body is assembled from multiple standard sections. Traditional standard sections are mainly divided into two categories: integral and segmented. Among them, segmented sections are more popular in the market due to their high safety and reliability, convenient transportation, convenient storage, and low maintenance costs.

[0004] Currently, during the installation of segmented standard sections, workers mainly assemble the segmented structures sequentially on-site using lifting equipment. Due to limitations at the construction site, individual segmented structures may need to be flipped multiple times and subjected to friction and collisions with the ground, resulting in wear and scratches on the paint of some structural surfaces. In severe cases, improper operation may also cause localized deformation of some standard section members, posing certain safety hazards to the tower's standard sections. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to address the above-mentioned shortcomings by proposing an installation bracket for tower crane segmented standard sections. Through the integrated bracket base design, the segmented structure of the tower crane standard section can be placed on the base first and then connected in pairs, avoiding multiple flipping and moving during the installation of the segmented structure of the tower crane standard section, and has the function of standard and rapid installation.

[0006] To address the aforementioned technical problems, in a first aspect, this application proposes a mounting bracket for a tower crane's standard section, comprising:

[0007] The base consists of four slotted seats, four grid connectors, and eight connecting ear plates. The slotted seats are square plate structures with grooves. The four slotted seats are connected in pairs by grid connectors to form a frame. A connecting ear plate is fixed on each of the two outer surfaces of each slotted seat.

[0008] External support structure I is a stable triangular frame structure formed by connecting and fixing horizontal rod I, vertical rod I, and diagonal rod I.

[0009] The external support structure II is a stable triangular frame structure formed by connecting and fixing horizontal rod II, vertical rod II, and diagonal rod II.

[0010] The internal support structure consists of an internal support pad, two stop bars, and two internal support rubber pads, which are fixed to the upper surface of the base.

[0011] The base has an external support structure I, an external support structure II, and an internal support structure installed at its four corners. The external support structure I and the external support structure II are fixed to the connecting lugs of the base.

[0012] In one or more alternative embodiments, the external support structure I further includes a rubber pad I, which is disposed on the inner side of the top of the vertical rod I and has a width equal to that of the vertical rod I. The horizontal rod I and the vertical rod I are connected at their ends and fixed to the connecting lug plate of the slotted seat.

[0013] In one or more alternative embodiments, the external support structure II further includes a rubber pad II, which is disposed on the inner side of the top of the vertical rod II and has a width equal to half the width of the vertical rod II. The horizontal rod II and the vertical rod II are connected at their ends and fixed to the connecting lug plate of the slotted seat.

[0014] In one or more alternative embodiments, the base provides a frame for mounting standard tower crane sections.

[0015] In one or more alternative embodiments, the grid connector is made of square steel, and the slotted seat and connecting ear plate are both made of steel plate.

[0016] In one or more alternative embodiments, the horizontal bar I, vertical bar I, and diagonal bar I are all made of I-beams; the horizontal bar II, vertical bar II, and diagonal bar II are all made of I-beams.

[0018] In one or more alternative embodiments, the inner support bolt hole is designed at one corner of the inner support pad, and the stop bar is fixed at the corner position opposite to the inner support bolt hole; the stop bar is made of angle steel, and the inner support pad is made of steel plate.

[0019] In one or more alternative embodiments, the mounting bracket is completed using the following steps:

[0020] The first external support structure I and the first external support structure II are connected to the connecting lugs of the base on side A by bolts.

[0021] Depending on the intended placement, external support structure I is set on the side of the tower crane standard section structure with vertical rods, and external support structure II is set on the side of the tower crane standard section structure without vertical rods.

[0022] Place the standard section structure of the tower crane on the base, and insert the bottom of the standard section structure into the groove of the slotted seat, so that the standard section structure of the tower crane is slightly tilted outward to ensure that its self-weight is borne by the outer support structure I and the outer support structure II.

[0023] An internal support structure is connected to the base by bolts to assist in supporting the standard segmental structure of the tower crane;

[0024] Following the steps described above, connect the second external support structure I and the second external support structure II to the base connecting lugs on side B using bolts; place the standard segmental structure of the hoisting tower crane on side B and install the internal support structure on side B;

[0025] The standard sections of the tower crane on side A and side B are connected by fastening bolts to form a stable frame structure.

[0026] Repeat the above steps to install the standard section structure of the tower crane on sides C and D in sequence, so that the standard section structure of the tower crane forms a complete standard section structure.

[0030] Place the standard section structure of the tower crane on the base, and insert the bottom of the standard section structure into the groove of the slotted seat, so that the standard section structure of the tower crane is slightly tilted outward to ensure that its self-weight is borne by the outer support structure I and the outer support structure II.

[0049] like Figure 1-2 As shown, the present invention provides an installation bracket for a standard section of a tower crane, characterized in that it includes a base 1, four external support structures I2, four external support structures II3, and four internal support structures 4. One external support structure I2, one external support structure II3, and one internal support structure 4 are respectively installed at the four corners of the base 1. The internal support structure 4 is fixed to the upper surface of the base 1, and the external support structures I2 and II3 are respectively fixed to the connecting lugs 1-3 of the base 1.

[0050] like Figure 3 As shown, the base 1 consists of four slotted seats 1-1, four grid connectors 1-2, and eight connecting ear plates 1-3. The slotted seats 1-1 are square plate structures with grooves, and the built-in right-angled grooves facilitate the insertion of the bottom of the tower crane standard segment structure 0. The grid connectors 1-2 are made of square steel, and the slotted seats 1-1 and connecting ear plates 1-3 are all made of steel plates. During installation, according to the shape of the tower crane standard segment structure 0, the right-angled grooves of the slotted seats 1-1 face outwards, and the four slotted seats 1-1 are connected in pairs through the grid connectors 1-2 to form a frame. A connecting ear plate 1-3 is welded to each of the two outer surfaces of each slotted seat 1-1.

[0051] like Figure 4As shown, the external support structure I2 consists of a horizontal rod I2-1, a vertical rod I2-2, a diagonal rod I2-3, and a rubber pad I2-4. The horizontal rod I2-1, vertical rod I2-2, and diagonal rod I2-3 are welded together to form a stable triangular frame structure. The rubber pad I2-4 is placed on the inner side of the top of the vertical rod I2-2, and its width is equal to the width of the vertical rod I2-2. The horizontal rod I2-1 and the vertical rod I2-2 are fixed to the connecting lug 1-3 of the slotted seat 1-1 through bolt holes I2-5 on the connecting end. The horizontal rod I2-1, vertical rod I2-2, and diagonal rod I2-3 are all made of I-beams.

[0052] like Figure 5 As shown, the external support structure II3 consists of a horizontal rod II3-1, a vertical rod II3-2, a diagonal rod II3-3, and a rubber pad II3-4. The horizontal rod II3-1, vertical rod II3-2, and diagonal rod II3-3 are welded together to form a stable triangular frame structure. The rubber pad II3-4 is placed on the inner top surface of the vertical rod II3-2, and its width is equal to half the width of the vertical rod II3-2. The horizontal rod I3-1 and the vertical rod I3-2 are fixed to the connecting lug 1-3 of the slotted seat 1-1 through bolt holes I3-5 on the connecting end. The horizontal rod II3-1, vertical rod II3-2, and diagonal rod II3-3 are all made of I-beams.

[0053] like Figure 6 As shown, the inner support structure 4 consists of an inner support plate 4-1, two stop rods 4-2, and two inner support rubber pads 4-3. An inner support bolt hole 4-4 is provided at one corner of the inner support plate 4-1. The bottoms of the two stop rods 4-2 are welded to the inner support plate 4-1 and are located at the corner opposite to the angle with the inner support bolt hole 4-4.

The stop rods 4-2 are made of angle steel, and the inner support plate 4-1 is made of steel plate.

[0054] like Figure 7 As shown, firstly, the first external support structure I2 and the first external support structure II3 are connected to the connecting lugs 1-3 of the base 1 on surface A using bolts. Based on the intended placement of the tower crane standard section structure 0, external support structure I2 is positioned on the side of the tower crane standard section structure 0 with vertical rods, and external support structure II3 is on the side of the tower crane standard section structure 0 without vertical rods. Then, the tower crane standard section structure 0 is placed on the base 1 by hoisting, with its bottom inserted into the groove of the slotted seat 1-1, and the tower crane standard section structure 0 is slightly tilted outwards to ensure its weight is borne by external support structures I2 and II3. Then, an internal support structure 4 is connected to the base 1 using bolts to further support the tower crane standard section structure 0; subsequently, as... Figure 8 As shown, following the steps described above, the second external support structure I2 and the second external support structure II3 are connected to the connecting lugs 1-3 of the base 1 on side B using bolts. The standard segment structure 0 of the hoisting tower crane is placed on side B, and the internal support structure 4 on side B is installed. At this time, the operators connect the standard segment structure 0 of the tower crane on side A and side B using fastening bolts to form a stable frame structure; repeat the above procedures, as follows... Figure 9 , Figure 10 As shown, the standard section structure 0 of the tower crane is installed sequentially on sides C and D, forming a complete standard section structure. Finally, the top crossbar of the tower crane is installed, and the standard section is removed from the base 1 by hoisting.

[0055] This invention provides an installation frame for the standard tower crane section through the base 1, and relies on the external support structure I2, external support structure II3, and internal support structure 4 to support the standard tower crane section panel structure during the installation process. It has the advantages of accurate positioning and easy operation, while avoiding problems such as repeated flipping of the standard tower crane section panel structure and contact with the ground. The corresponding rubber gaskets can also effectively prevent the paint of the standard section panel structure from being damaged during installation, and have a good protective effect on the standard section structure.
