Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure demolition technology, and in particular to a novel steel structure demolition equipment. Background Technology
[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and plates, and the components or parts are usually connected by welds, bolts or rivets.
[0003] Steel structures age significantly over long-term use. To ensure building safety, specialized demolition equipment such as hydraulic shears is typically used to dismantle them. However, the friction generated by the hydraulic shears during contact with the steel structure surface can easily cause small debris to fly everywhere, thus affecting the safety of the demolition process.
[0004] Therefore, a new type of steel structure demolition equipment is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a new type of steel structure demolition equipment to solve the above-mentioned problems and improve the problem that hydraulic shears are prone to producing small flying debris during the demolition of steel structures.
[0006] This utility model achieves the above-mentioned objectives through the following technical solution: a novel steel structure demolition device, comprising: a hydraulic shear; and a splash-proof mechanism. The splash-proof mechanism includes a dust collection box fixedly connected to the front and rear ends of the hydraulic shear. A fan is connected to the top of the dust collection box. Inclined blocks are fixedly connected to both sides of the inner wall of the dust collection box. A filter plate is slidably connected to the upper end of the inner wall of the dust collection box. The lower end of the filter plate's surface is V-shaped, and one end of the dust collection box's surface is trumpet-shaped. Through the fan and dust collection box, splashes generated during steel structure demolition are collected, thus preventing smaller debris from scattering and ensuring the safety of the hydraulic shears during steel structure demolition. The V-shaped filter plate prevents debris from entering the fan and reduces the area of debris adhering to the filter plate, thereby ensuring the fan's effective adsorption of smaller debris.
[0007] Preferably, the top of the exhaust fan is connected to an exhaust pipe, and the inner wall of the exhaust pipe is rotatably connected to a fan wheel, with eccentric wheels fixedly connected to both ends of the fan wheel.
[0008] Preferably, a plurality of springs are fixedly connected to the top of the filter plate, and the top ends of the springs are fixedly connected to the inner top wall of the dust collection box. Through the exhaust pipe, impeller, eccentric wheel and springs, the exhaust fan drives the filter plate to move up and down reciprocally in the exhaust, thereby quickly shaking off the debris attached to the filter plate and avoiding excessive debris from adhering to the filter plate and causing filter plate blockage.
[0009] Preferably, a filter screen is fixedly connected to the upper end of the inner wall of the exhaust pipe.
[0010] Preferably, a shield is fixedly connected to the upper surface of the exhaust pipe. The shield's filter screen prevents impurities from entering the exhaust fan through the exhaust pipe.
[0011] Preferably, a rubber plate is snapped onto the lower end of the inner wall of the dust collection box, and limit blocks are fixedly connected to both sides of the inner wall of the dust collection box.
[0012] Preferably, screws are threaded onto both sides of the top of the rubber sheet, and the threads of the screws are threaded onto the inner wall of the dust collection box. The limiting block restricts the engagement position of the rubber sheet, thereby ensuring that the screws on the dust collection box are precisely threaded within the rubber sheet.
[0013] The beneficial effects of this utility model are:
[0014] 1. By using an exhaust fan and a dust collection box, the flying debris generated during the dismantling of the steel structure is collected. Compared with the existing steel structure, which is prone to flying around when small debris is dismantled, this method avoids the flying around of small debris and ensures the safety of the hydraulic shears in dismantling the steel structure. The filter plate with a "V" shape at the bottom of the surface blocks the debris in the dust collection box from entering the exhaust fan and reduces the area of debris attached to the filter plate, thereby ensuring the exhaust fan's adsorption effect on small debris.
[0015] 2. Through the exhaust pipe, impeller, eccentric wheel and spring, the exhaust fan drives the filter plate to move up and down in the exhaust, thereby shaking off the debris attached to the filter plate quickly and avoiding excessive debris from sticking to the filter plate and causing it to become clogged.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] In practical implementation: such as Figure 1-4 As shown, a novel steel structure demolition device includes: a hydraulic shear 1; and a splash-proof mechanism 2. The splash-proof mechanism 2 includes a dust collection box 21 fixedly connected to the front and rear ends of the hydraulic shear 1. An exhaust fan 22 is connected to the top of the dust collection box 21. Inclined blocks 23 are fixedly connected to both sides of the inner wall of the dust collection box 21. A filter plate 24 is slidably connected to the upper end of the inner wall of the dust collection box 21. The lower end of the surface of the filter plate 24 is V-shaped, and one end of the surface of the dust collection box 21 is trumpet-shaped. The exhaust fan 22 is an axial flow exhaust fan 22.
[0023] The hydraulic shear 1 works by using the force generated by liquid pressure to complete the shearing operation. When the hydraulic station supplies pressurized oil, the oil pushes the piston of the oil cylinder to move, which in turn causes the lower and upper cutter holders to clamp the metal material. Subsequently, the cylinder continues to move, causing the lower cutter holder to descend rapidly, completing the shearing action.
[0024] When steel structure demolition is required, the hydraulic shears 1 are threaded onto the excavator using bolts and nuts. By operating the control panel on the excavator, the hydraulic shears 1 are lifted to the steel structure to be demolished. The hydraulic shears 1 and exhaust fan 22 are automatically activated. Driven by hydraulic fluid, the upper blade of the hydraulic shears 1 falls onto the steel structure and moves towards the lower blade, thus performing the demolition operation. The exhaust fan 22 draws air out of the dust collection box 21, creating a negative pressure inside. This allows the dust collection box 21 to absorb outside air and debris generated during shearing. Most of the debris entering the dust collection box 21 is guided down to the lower inner wall of the dust collection box 21 by two inclined blocks 23. Because the two inclined blocks 23 are shaped like an "8," the debris at the lower inner wall of the dust collection box 21 is less likely to be thrown out. After the steel structure demolition is completed, the hydraulic shears 1 and exhaust fan 22 are automatically shut off by operating the control panel on the excavator.
[0025] like Figure 4 As shown, the top of the exhaust fan 22 is connected to an exhaust pipe 25, the inner wall of the exhaust pipe 25 is rotatably connected to a fan wheel 26, both ends of the fan wheel 26 are fixedly connected to an eccentric wheel 27, the top of the filter plate 24 is fixedly connected to several springs 28, the top of the springs 28 is fixedly connected to the inner top wall of the dust collection box 21, the upper end of the inner wall of the exhaust pipe 25 is fixedly connected to a filter screen 29, and the upper surface of the exhaust pipe 25 is fixedly connected to a cover 210.
[0026] Air in the dust collection box 21 is filtered by the filter plate 24 and flows into the exhaust fan 22. The filter plate 24 prevents debris from being carried into the exhaust fan 22 by the air. The air in the exhaust fan 22 flows into the exhaust pipe 25. The air flow in the exhaust pipe 25 drives the impeller 26 to rotate. The rotating impeller 26 drives the eccentric wheel 27 to rotate. The highest point of the eccentric wheel 27 touches the filter plate 24, thereby pushing the filter plate 24 to move upward and compressing the spring 28. The highest point of the eccentric wheel 27 moves away from the filter plate 24. The elastic force of the spring 28 pushes the filter plate 24 to move downward, thereby causing the filter plate 24 to move up and down repeatedly in the dust collection box 21, causing the debris attached to the filter plate 24 to fall off.
[0027] like Figure 2 As shown, a rubber plate 211 is snapped onto the lower end of the inner wall of the dust collection box 21, and limit blocks 212 are fixedly connected to both sides of the inner wall of the dust collection box 21. Screws 213 are threaded onto both sides of the top of the rubber plate 211, and the surface of the screws 213 is threaded onto the inner wall of the dust collection box 21.
[0028] When cleaning the dust collection box 21, use an electric screwdriver to move the screw 213 away from the rubber plate 211, pull the rubber plate 211 to open the front end of the dust collection box 21, and then clean the debris inside the dust collection box 21. After cleaning, snap the rubber plate 211 into the dust collection box 21 and make it abut against the front end of the limit block 212. Use an electric screwdriver to quickly thread the screw 213 into the rubber plate 211.
[0029] In use, this utility model automatically activates the hydraulic shears 1 and the exhaust fan 22. Driven by hydraulic fluid, the upper blade holder of the hydraulic shears 1 falls onto the steel structure and approaches the lower blade holder, thus performing demolition work on the steel structure. The exhaust fan 22 draws air out of the dust collection box 21, creating a negative pressure inside the dust collection box 21. This causes the dust collection box 21 to absorb outside air and debris generated during shearing. Most of the debris entering the dust collection box 21 is guided down to the lower inner wall of the dust collection box 21 by the two inclined blocks 23. Because the two inclined blocks 23 are shaped like an "8", the debris at the lower inner wall of the dust collection box 21 is difficult to fly out again, thus facilitating dust collection. Air inside the dust collection box 21 is filtered by the filter plate 24 and flows into the exhaust fan 22. The filter plate 24 prevents debris from being carried into the exhaust fan 22 by the air. The air inside the exhaust fan 22 flows into the exhaust pipe 25. The gas flow in the exhaust pipe 25 drives the impeller 26 to rotate. The rotating impeller 26 drives the eccentric wheel 27 to rotate. The highest point of the eccentric wheel 27 touches the filter plate 24, thereby pushing the filter plate 24 upward and squeezing the spring 28. The highest point of the eccentric wheel 27 moves away from the filter plate 24. The elastic force of the spring 28 pushes the filter plate 24 downward, thereby causing the filter plate 24 to move up and down repeatedly in the dust collection box 21, causing the debris attached to the filter plate 24 to fall off.
[0030] It should be noted that the hydraulic shear 1, dust collection box 21 and exhaust fan 22 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the hydraulic shear 1 and exhaust fan 22 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.
[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
