Description

Technical Field

[0001] This utility model belongs to the field of auxiliary accessories for tower cranes, and particularly relates to an adjustable tie rod bracket. Background Technology

[0002] With the development of the construction industry and the needs of construction, tower cranes are becoming increasingly larger, resulting in longer and thicker counterweight booms; this significantly increases their weight, making installation (and dismantling) more difficult. During tower crane installation (and dismantling), the heavy boom makes lifting (lowering) difficult. When this happens, the current common practice is:

[0003] 1. The work is completed by workers carrying it by hand and on their shoulders; this method is difficult, strenuous, and poses safety risks.

[0004] 2. The task is completed by the auxiliary hook of the truck crane; this method requires the truck crane to have an auxiliary hook function, but it is inconvenient to operate, inaccurate to control, and also poses safety risks. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, this utility model provides an adjustable tie rod support. Through labor-saving rotational movement, the heavy tie rod can be adjusted up and down, eliminating the need for manual lifting and carrying, thereby making tower crane installation convenient, safe, reliable, and cost-effective.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an adjustable tie rod bracket, including a rotating bracket, an ear seat, a large nut, a screw, a stop plate, a support, and a connector. The rotating bracket is hinged to the ear seat, the ear seat is connected to one end of the screw, and the other end of the screw is connected to the stop plate. The stop plate has an elongated oval hole. The aforementioned screw and stop plate are inserted into the support. The aforementioned screw is fitted with a large nut and a large washer for adjusting the position. One side of the support has a through hole, and an anti-rotation pin is inserted into the through hole. The anti-rotation pin is inserted into the through hole and also passes through the oval hole of the stop plate. The support is connected to its corresponding components through the connector.

[0007] In the above technical solution, the connecting member includes a pressure plate, the support and the pressure plate are connected at an acute angle, the pressure plate and the support are clamped outside the rectangular section of the balance arm, and are locked to the rectangular section of the balance arm by a number of bolts.

[0008] In the above technical solution, the connecting component includes an ear plate and a connecting seat. The ear plate is connected to the support, and the connecting seat is fixed to the main limb of the balance arm. The ear plate and the connecting seat are connected by bolts and nuts.

[0009] In the above technical solution, the ear seat, screw and stop plate are welded together in sequence to form a whole.

[0010] In the above technical solution, the length of the stop plate is less than the length of the support.

[0011] The beneficial effects of this utility model are: by rotating the large nut, the heavy tie rod can be adjusted up and down, eliminating the need for manual lifting and carrying, reducing the labor intensity of workers, and thus making tower crane installation convenient, safe, reliable, and cost-effective.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1An adjustable tie rod bracket is shown, comprising a rotating bracket 1, an ear seat 2, a large nut 3, a screw 5, a stop plate 6, a support 8, and a connector. The rotating bracket 1 is hinged to the ear seat 2. The ear seat 2 is connected to one end of the screw 5, and the other end of the screw 5 is connected to the stop plate 6. The stop plate 6 has an elongated oval hole. The screw 5 and the stop plate 6 are inserted into the support 8. The screw 5 is fitted with a large nut 3 and a large washer 4 for adjusting the position. One side of the support 8 has a through hole, into which an anti-rotation pin 7 is inserted. The anti-rotation pin 7 is inserted into the through hole and also passes through the oval hole of the stop plate 6. The support 8 is connected to its corresponding components through the connector.

[0022] like Figure 2 , Figure 3 As shown, the connecting component includes a pressure plate 9, and the support 8 is connected to the pressure plate 9 at an acute angle. The pressure plate 9 and the support 8 are clamped outside the rectangular section 13 of the balance arm, and are locked to the rectangular section 13 of the balance arm by several bolts 10, spring washers 11, and nuts 12. When it is necessary to extend or shorten, simply tighten the large nut 3 to extend or shorten the bracket. Its stroke can be customized according to specific actual requirements.

[0023] like Figure 4 , Figure 5 The connecting components include an ear plate 14 and a connecting seat 15. The ear plate 14 is connected to the support 8, and the connecting seat 15 is fixed to the main limb of the balance arm 16. The ear plate 14 and the connecting seat 15 are connected by bolts and nuts. Before installation, insert the ear seat 2, screw 5, and stop plate 6 into the square tube of the support 8 as a whole, aligning the waist hole of the stop plate 6 with the through hole side of the support 8, and insert the anti-rotation pin 7. At this time, place the long tie rod in the channel steel of the rotating bracket 1. During installation, extend the tie rod bracket and turn the large nut 3 to adjust it to the required height. After installation, retract the tie rod bracket to the lowest position and lay it down clockwise to avoid occupying space. During disassembly, straighten the tie rod bracket and turn the large nut 3 to adjust the height so that the channel steel of the rotating bracket 1 contacts the long tie rod. Remove the tie rod pin to allow the tie rod bracket to bear the load, and turn the large nut 3 in the opposite direction to lower the tie rod bracket to the lowest position. The travel of the tie rod bracket can be customized according to specific requirements.

[0024] In the above technical solution, the lug 2, screw 5, and stop plate 6 are sequentially welded together to form a whole. Before welding, the large nut 3 and large washer 4 need to be installed on the screw 5.

[0025] In the above technical solution, the length of the stop plate 6 is less than the length of the support 8. The stop plate structure is as follows: Figure 6 , Figure 7 As shown. After the stop plate 6 is connected to the screw 5, it is inserted into the support 8. Therefore, the stop plate cannot be too long.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
