Abstract
Description
Technical Field
[0001] The invention relates to the technical field of power plant construction equipment, in particular to a construction frame used for power plant construction. Background Art
[0002] Power plants require large amounts of fuel to generate electricity, and the combustion of this fuel inevitably requires a large number of chimneys. Traditional suspended construction frame systems face two core difficulties when performing internal corrosion protection or lining maintenance work on large chimneys in thermal power plants:
[0003] First, there was the issue of dynamic instability in the construction frame. Suspended from the chimney by steel cables, the frame was subjected to constant swaying caused by high-altitude turbulence and the impact of the winch starting and stopping. This swaying not only made it difficult for construction workers to stand, but also posed a risk of collision between the frame and the acid-resistant bricks of the chimney wall, causing the brittle lining to peel and threatening the structural safety.
[0004] Secondly, the extremely harsh optical environment. The high concentration of dust and water vapor inside the chimney doubles the attenuation of light, while the carbon black deposits on the inner wall further exacerbate the blind spots in the shadowed areas. This "semi-blind" working environment undoubtedly increases the difficulty of construction. Summary of the Invention

[0049] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.
[0050] See also Figures 1 to 4 The present invention provides a technical solution: a construction frame for power plant construction, comprising a bottom bracket 1 and an upper bracket 2, wherein the bottom bracket 1 is fixedly mounted below the upper bracket 2 through detachable support columns 3 provided at four corners;
[0051] The bottom bracket 1 is the basic support platform, providing the base for the entire structure, and its backward movement is part of the lever action.
[0052] The support columns 3 are located at the four corners of the bottom bracket and detachably connect the bottom bracket to the upper bracket 2. Their main function is to transmit the force and maintain the relative position relationship between the upper and lower brackets. Their rigidity is crucial to the formation of the leverage effect.
[0053] The front portion of the upper bracket 2 becomes the active contact point.
[0054] The pushing assembly includes a hydraulic rod group 31 arranged side by side, and the hydraulic rod group 31 can squeeze the wall by extending the output rod;
[0055] The four corners of the upper bracket 2 are provided with a hoisting structure 4;
[0056] The hoisting structure 4 includes a lifting ring 41 , the bottom of which is fixedly connected to a fixing pile 42 ; the four corners of the upper bracket 2 where the lifting ring 41 is located are the key fulcrums of the entire lever system.
[0057] A light strip structure 5 is provided on the outer side of the upper bracket 2;
[0058] The light strip structure 5 includes a lighting lamp 51, and the lower end of the lighting lamp 51 is connected to the support plate 52 through a rotating shaft;
[0059] The front end side wall of the upper bracket 2 is provided with an air-avoiding recess 6;
[0060] Support wheel structures 7 are provided at both ends of the air-avoiding recess 6;
[0061] The support wheel structure 7 includes a support wheel 71 , and a surface of the support wheel 71 is provided with an anti-slip groove.
[0062] The upper bracket 2 moves forward, pushing the support wheel 71 to finally abut against and compact the wall. The anti-slip groove increases the friction of the contact surface to prevent sliding.
[0063] In this embodiment, the hydraulic rod assembly 31 is fixedly mounted on the bottom bracket 1 via two sets of mounting brackets 32. A guide bracket 33 is provided on the output shaft of the hydraulic rod assembly 31, and the guide bracket 33 is fixedly mounted on the bottom bracket 1. The guide bracket 33 guides the linear motion of the hydraulic rod output shaft, ensuring that the initial thrust is accurately and without deviation applied to the wall, providing a correct starting point for subsequent lever action.
[0064] In this embodiment, a support pad 34 is installed at the end of the output shaft. Made of a wear-resistant soft rubber material, the pad provides a cushioning effect against the wall. The high friction coefficient ensures a secure attachment point between the output shaft and the wall, preventing slippage and ensuring effective transmission of initial thrust.
[0065] In this embodiment, the lifting rings 41 are arranged at the four corners of the upper bracket 2, and the fixing piles 42 are fixedly installed in the side walls of the upper bracket 2, providing extremely stable anchoring points for the lifting rings 41, so that they can withstand the huge bending moment and pressure generated by the lever action.
[0066] In this embodiment, the surface of the support plate 52 is coated with reflective material, and a connecting frame 53 is provided below the support plate 52 . The bottom of the connecting frame 53 is fixedly connected to the outer wall of the upper bracket 2 .
[0067] In this embodiment, the air-avoiding recess 6 is arc-shaped, and a light strip 61 is provided on the outer side of the air-avoiding recess 6. This shape optimizes the front structure of the upper bracket, reduces stress concentration, and helps to more evenly disperse the contact pressure when the support wheel is against the wall, especially on uneven or curved walls, and can better play a supporting role.
[0068] In this embodiment, wheel frames 72 are provided on both sides of the support wheel 71. The wheel frames 72 are fixedly mounted on the upper bracket 2. The wheel frames 72 provide high-strength support for the support wheel 71, ensuring that it can withstand the huge pressure ultimately transmitted by the leverage action and stably transmit this force back to the main structure of the upper bracket 2.
[0069] In this embodiment, the support column 3 is fixedly connected to the bottom of the fixing pile 42 .
[0070] Working principle: The construction frame is moved to the target position so that it is close to the wall as a whole. The hydraulic rod group 31 is activated, and its output rod is extended under the guidance of the guide frame 33. The support pad 34 presses the wall surface, generating a strong initial thrust acting on the front of the bottom bracket 1. This thrust is transmitted through the bottom bracket 1 to the support column 3 connected thereto. The support column 3 transmits the effect of the force upward through the rigid connection between its upper end and the fixed pile 42 / upper bracket 2. Since the upper bracket 2 is effectively constrained at the four corners by the fixed pile 42 and the ring structure 41, the front end of the bottom bracket 1 is pushed forward (F1, which causes the entire structure to produce a lever effect around the ring: the tail of the bottom bracket 1 has a tendency to move backward, while the front of the upper bracket 2 has a tendency to move forward.
[0071] After the front of upper support 2 establishes a forward motion, support wheels 71 are rapidly pushed toward and ultimately compact the wall. At this point, the support wheels exert a force on the wall, which in turn generates a reaction force F3 on the support wheels. Simultaneously, the hydraulic rod output rod continues to press against the wall, and the reaction force generated by the wall continuously acts on the front of bottom support 1. At this point, three key force points of action form a stable triangular support structure:
[0072] Force 1: Lifting ring / fixed pile position,
[0073] Force 2: The contact point between the output rod end of the hydraulic rod and the wall,
[0074] Force three: contact point between support wheel and wall,
[0075] Ensure the balance and rigidity of the entire structure.
[0076] It is understood from common technical knowledge that the present invention may be implemented by other embodiments that do not depart from its spirit or essential features. Therefore, the embodiments disclosed above are, in all respects, merely illustrative and not exclusive. All modifications within the scope of the present invention or equivalent to the scope of the present invention are intended to be encompassed by the present invention.
