Description

Technical Field

[0001] The invention relates to a novel support structure for a base of an electric control element of a tower crane with adjustable struts, belonging to the technical field. Background Art

[0002] At present, the connecting rod structure is widely used in the machinery, construction and civil engineering industries, mainly used for the support system of mechanical equipment and structural monomers. Although the structural forms of the rods are varied, the most common ones are round tube welded rods and square tube welded rods. The length of these rods is fixed and cannot be adjusted, which makes them unable to adapt to mechanical equipment and structural monomers of different sizes and needs to be customized separately, which not only wastes a lot of equipment resources, but also increases the difficulty of installation.

[0003] The engineering machinery field requires that the brace has strong stability and load-bearing capacity, and is easy to maintain to ensure the safety and stability of the equipment. Conventional brace assemblies are composed of round tubes, round plates, square plates, ear plates, square tubes and other devices. Generally, they are divided into round rod welded braces and square tube welded braces, and the length cannot be adjusted, which makes processing difficult and installation difficult. The round plate and square plate are installed on the outside of the round tube and square tube, and the ear plates are welded on the round plate and square plate. The length of the brace is fixed, and it is impossible to support mechanical equipment and structural monomers of different sizes. Individual customization is required, which wastes too much equipment resources and is not conducive to the control of the overall cost and construction period of the engineering project. Summary of the invention

[0004] In order to overcome the shortcomings of the above-mentioned prior art, the present invention provides a new type of tower crane electric control element base support structure with adjustable struts. The struts have the function of flexibly adjusting the length and can be adjusted in length according to actual needs, so that they are widely used in the support of mechanical equipment and structural units with different size requirements.

[0005] The present invention is realized by the following technical scheme: a novel support structure of the electric control element base of a tower crane with adjustable struts, comprising a double-headed screw, a left-handed nut, a right-handed nut, a main chord and a joint, the two ends of the double-headed screw are respectively provided with a left thread and a right thread, the thread rotation directions of the left thread and the right thread are opposite, one end of the left thread of the double-headed screw is connected to one end of the main chord, and one end of the right thread of the double-headed screw is connected to one end of the joint, and the left-handed nut and the right-handed nut respectively lock the main chord and the joint with the double-headed screw. The left thread and the right thread of the double-headed screw have equal diameters, equal pitches, the same number of thread heads, and equal thread lengths.

[0006] The middle part of the double-headed screw is provided with a pin hole.

[0007] The other end of the main chord is provided with two parallel ear plates, on which pin holes are drilled, and the axis of the pin holes is perpendicular to the axis of the double-headed screw; the other end of the joint is provided with two parallel ear plates, on which pin holes are drilled, and the axis of the pin holes is perpendicular to the axis of the double-headed stud.

[0008] The pin holes at the ends of the main chord and the joint have the same size. After the two ends of the support structure are stably connected to the beam structure and the electric control element base, the main chord and the joint are fixed.

[0009] After the main chord and the joint are fixed, the length of the supporting structure can be adjusted by rotating the double-headed screw.

[0010] The beneficial effects of the present invention are as follows: the unique structure of the double-headed adjustment screw enables the support rod to be flexible and retractable. Since the threads at both ends of the screw have opposite rotation directions, when the screw is rotated, the main chord and the joint can be synchronously retracted and retracted along the axial direction, thereby achieving precise adjustment of the distance of the support structure. By rotating the double-headed adjustment screw, the length of the support structure can be quickly adjusted without the need for complex tools and equipment, which greatly simplifies the operation process and improves work efficiency. Locking nuts are installed at both ends of the adjustment screw, and the adjusted length of the support structure is locked by tightening the nuts, preventing the adjustment screw from moving during operation.

In addition, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] like Figures 1 to 4 A new type of support structure for the base of an electric control element of a tower crane with adjustable struts is shown, comprising a double-headed screw rod 1, a left-handed nut 2, a right-handed nut 3, a main chord 4 and a joint 5. The two ends of the double-headed screw rod 1 are respectively provided with a left thread and a right thread, and the thread rotation directions of the left thread and the right thread are opposite. One end of the left thread of the double-headed screw rod 1 is connected to one end of the main chord 4, and one end of the right thread of the double-headed screw rod 1 is connected to one end of the joint 5. The left-handed nut 2 and the right-handed nut 3 respectively lock the main chord 4 and the joint 5 with the double-headed screw rod 1.

[0017] The left and right threads of the double-headed screw 1 have equal diameters, equal pitches, the same number of thread starts, and equal thread lengths.

[0018] The middle part of the double-headed screw 1 is provided with a pin hole 6 to facilitate the adjustment of the length of the supporting structure.

[0019] The other end of the main chord 4 is provided with two parallel ear plates, on which pin holes are drilled, and the axis of the pin holes is perpendicular to the axis of the stud 1; the other end of the joint 5 is provided with two parallel ear plates, on which pin holes are drilled, and the axis of the pin holes is perpendicular to the axis of the stud 1.

[0020] The pin holes at the ends of the main chord 4 and the joint 5 have the same size. After the two ends of the support structure are stably connected to the beam structure and the base of the electric control element, the main chord 4 and the joint 5 are fixed.

[0021] After the main chord 4 and the joint 5 are fixed, the length of the supporting structure can be adjusted by rotating the double-headed screw 1.

[0022] When both ends of the support structure are stably connected to the beam structure and the base of the electric control element, the main chord 4 and the joint 5 are fixed and cannot rotate. At this time, if the distance of the support structure needs to be adjusted, it is only necessary to rotate the double-headed screw 1. As the double-headed screw 1 rotates, the main chord 4 and the joint 5 will simultaneously expand or contract along the axial direction, thereby achieving precise adjustment of the length of the support structure.

[0023] In actual use, the user first needs to assemble the main chord 4 and the joint 5 with the ear plate of the support part and the base, and ensure the stability between them through the pin and the pin connection. After that, the pin is inserted into the pin hole of the double-headed screw 1, and the length of the support structure is adjusted by rotating the double-headed screw 1 to meet different support requirements. This design is easy to operate and has a wide adjustment range, which provides great convenience for users. Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
