Description
Technical Field
[0001] This utility model relates to the field of explosion-proof technology for excavators, specifically to an explosion-proof excavator with both oil and electric power. Background Technology
[0002] This dual-power (oil and electric) explosion-proof excavator integrates advanced technology and safety concepts, specifically designed for special high-risk environments. It employs a hybrid "dual-power" fully hydraulic drive technology, using an internal combustion engine and an electric motor to drive two hydraulic power systems and one actuator system respectively, achieving efficient operation. During electric operation, it utilizes an explosion-proof motor and fully enclosed electrical components, ensuring safety and fire prevention, allowing safe operation in flammable and explosive environments such as oil, natural gas, mining, and chemical plants. Furthermore, this excavator exhibits significant energy savings, with the overall cost of electric operation being only 30-40% of that of oil-powered operation. It also features low noise and zero emissions, and can be configured with various functions to achieve multi-purpose functionality.
[0003] Most existing explosion-proof excavators use an integrated sunroof, which is difficult to disassemble when maintenance or replacement is needed. In addition, the existing explosion-proof excavator door structure design is simple, which can easily cause the door to deform when subjected to a large impact, thereby causing injury to the operator inside, resulting in low practicality. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a dual-power explosion-proof excavator that is both oil-powered and electric-powered, which can effectively solve the problems in the prior art.
[0005] The technical solution adopted by this utility model is: a dual-power explosion-proof excavator, including an excavator body and a control room. An explosion-proof skylight is provided on the top of the control room. An explosion-proof door is hinged to one side of the control room. A sealing strip is embedded in the outer surface of the explosion-proof skylight. Explosion-proof glass is embedded in the inner side of the explosion-proof door. A handle is fixedly installed at the end of the explosion-proof door away from the control room. The explosion-proof door includes an impact-resistant layer, a buffer layer at the end of the impact-resistant layer near the control room, a heat insulation layer at the end of the buffer layer away from the impact-resistant layer, and a reinforced inner layer at the end of the heat insulation layer away from the buffer layer.
[0006] Preferably, the explosion-proof skylight and the top of the control room are connected by a plug-in joint, and two identical sets of sealing strips are provided, with the two sets of tops of the control room located symmetrically distributed on the outer surface of the explosion-proof skylight.
[0007] The above technical solution allows for the detachable installation of the explosion-proof skylight by connecting it to the top of the control room, facilitating future maintenance. Furthermore, by embedding two sets of sealing strips on the outer surface of the skylight, the airtightness between the skylight and the control room is significantly improved, effectively preventing external flammable and explosive gases, dust, and moisture from entering the control room and ensuring a safe working environment for personnel.
[0008] Preferably, the impact-resistant layer is made of high-strength alloy steel plate, and the thickness of the impact-resistant layer is 5mm to 10mm.
[0009] The above technical solution uses high-strength alloy steel plate for the impact-resistant layer. High-strength alloy steel plate has good impact resistance. By setting the thickness of the impact-resistant layer to 5mm to 10mm, it can not only ensure that the impact-resistant layer can effectively resist external impact forces, but also avoid the explosion-proof door becoming too heavy due to excessive thickness.
[0010] Preferably, the inner side of the buffer layer is provided with several sets of honeycomb-shaped cavities at equal intervals.
[0011] The above technical solution utilizes a honeycomb-shaped design with several groups of equally spaced cavities on the inner side of the buffer layer. This honeycomb design provides excellent cushioning, effectively dispersing and absorbing a significant amount of impact, thus protecting the driver's safety.
[0012] Preferably, the heat insulation layer is made of aluminum silicate cotton, and the thickness of the heat insulation layer is 15mm to 20mm.
[0013] The above technical solution uses aluminum silicate cotton as the insulation layer. Aluminum silicate cotton is a high-quality insulation material with good high temperature resistance and insulation performance. By setting the thickness of the insulation layer to 15mm to 20mm, it can be ensured that the insulation layer effectively blocks the external high temperature from being transmitted to the control room, thereby improving the working environment of the operators.
[0014] Preferably, the reinforcing inner layer is made of glass fiber reinforced plastic, and the thickness of the reinforcing inner layer is 1mm to 3mm.
[0015] The above technical solution uses glass fiber reinforced plastic as the reinforcing inner layer. Glass fiber reinforced plastic has advantages such as light weight, high strength, and corrosion resistance. By setting the thickness of the reinforcing inner layer to 1mm to 3mm, the strength of the reinforcing inner layer can be enhanced, while the weight of the explosion-proof door can be reduced.
[0016] Compared with the prior art, this utility model provides a dual-power explosion-proof excavator with both oil and electricity, which has the following advantages: 1. This dual-powered (oil and electric) explosion-proof excavator features a plug-in connection between the explosion-proof skylight and the top of the control room, allowing for detachable installation of the skylight for easy maintenance. Two sets of sealing strips are embedded in the outer surface of the skylight, significantly improving the airtightness between the skylight and the control room. This effectively prevents external flammable and explosive gases, dust, and moisture from entering the control room, ensuring a safe working environment for personnel. 2. This dual-power (oil and electric) explosion-proof excavator features a multi-layered explosion-proof door to enhance its explosion-proof strength. The impact-resistant layer is made of high-strength alloy steel, which offers excellent impact resistance. The buffer layer incorporates several evenly spaced honeycomb cavities, providing excellent cushioning and effectively dispersing and absorbing impacts to protect the operator. The insulation layer uses aluminum silicate cotton, a high-quality insulation material with excellent high-temperature resistance and insulation properties. The reinforcing inner layer is made of glass fiber reinforced plastic, which is lightweight, high-strength, and corrosion-resistant. With a thickness of 1mm to 3mm, the reinforcing inner layer enhances its strength while reducing the weight of the explosion-proof door. Attached Figure Description

[0019] 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.
[0020] Example 1: As Figure 1-6 As shown, the present invention provides a dual-power explosion-proof excavator, including an excavator body 1 and a control room 2. An explosion-proof skylight 3 is provided on the top of the control room 2. An explosion-proof door 4 is hinged to one side of the control room 2. A sealing strip 5 is embedded in the outer surface of the explosion-proof skylight 3. An explosion-proof glass 6 is embedded in the inner side of the explosion-proof door 4. A handle 7 is fixedly installed at the end of the explosion-proof door 4 away from the control room 2. The explosion-proof door 4 includes an impact-resistant layer 401, a buffer layer 402 is provided at the end of the impact-resistant layer 401 near the control room 2, a heat insulation layer 403 is provided at the end of the buffer layer 402 away from the impact-resistant layer 401, and a reinforced inner layer 404 is provided at the end of the heat insulation layer 403 away from the buffer layer 402.
[0021] Specifically, the explosion-proof skylight 3 and the top of the control room 2 are connected by a plug-in joint. Two identical sets of sealing strips 5 are installed on the top of the control room 2, symmetrically distributed on the outer surface of the explosion-proof skylight 3. The advantage is that by connecting the explosion-proof skylight 3 and the top of the control room 2 by a plug-in joint, the explosion-proof skylight 3 can be detached for easy maintenance. Furthermore, by embedding two sets of sealing strips 5 on the outer surface of the explosion-proof skylight 3, the sealing performance between the skylight 3 and the control room 2 is greatly improved, effectively preventing external flammable and explosive gases, dust, and moisture from entering the control room 2, ensuring a safe working environment for personnel.
[0022] Specifically, the impact-resistant layer 401 is made of high-strength alloy steel plate, and its thickness is 5mm to 10mm. The advantage is that by using high-strength alloy steel plate for the impact-resistant layer 401, which has excellent impact resistance, and by setting its thickness to 5mm to 10mm, it effectively resists external impacts while avoiding excessive weight for the explosion-proof door 4 due to excessive thickness.
[0023] Specifically, the inner side of the buffer layer 402 is provided with several sets of honeycomb-shaped cavities at equal intervals. The advantage is that by providing several sets of honeycomb-shaped cavities at equal intervals on the inner side of the buffer layer 402, the honeycomb design has good cushioning properties, effectively dispersing and absorbing a greater amount of impact, thus protecting the driver's safety.
[0024] Example 2: Figure 2-6As shown, this is an improvement on the previous embodiment.
[0025] Specifically, the insulation layer 403 is made of aluminum silicate cotton, and its thickness is 15mm to 20mm. The advantage is that by using aluminum silicate cotton for the insulation layer 403, a high-quality insulation material with excellent high-temperature resistance and insulation performance, and by setting the thickness of the insulation layer 403 to 15mm to 20mm, it is ensured that the insulation layer 403 effectively blocks the transmission of external high temperatures into the control room 2, thereby improving the working environment for operators.
[0026] Specifically, the reinforced inner layer 404 is made of glass fiber reinforced plastic, and its thickness is 1mm to 3mm. The advantage is that by using glass fiber reinforced plastic for the reinforced inner layer 404, which is lightweight, high-strength, and corrosion-resistant, and by setting its thickness to 1mm to 3mm, the strength of the reinforced inner layer 404 is enhanced while reducing the weight of the explosion-proof door 4.
[0027] Working Principle: During use, the explosion-proof skylight 3 is designed for plug-in installation at the top of the control room 2, allowing for detachable installation of the skylight 3 and facilitating later maintenance. Two sets of sealing strips 5 are embedded in the outer surface of the skylight 3, significantly improving the sealing between the skylight 3 and the control room 2, effectively preventing external flammable and explosive gases, dust, and moisture from entering the control room 2, ensuring a safe working environment for personnel. The explosion-proof door 4 adopts a multi-layer structure to enhance its explosion-proof strength. The impact-resistant layer 401 is made of high-strength alloy steel plate, which has excellent impact resistance. The thickness of the impact-resistant layer 401 is 5mm to 10mm, ensuring effective resistance to external impacts while avoiding excessive weight. Several honeycomb-shaped cavities are evenly spaced on the inner side of the buffer layer 402. The honeycomb design provides excellent cushioning, effectively dispersing and absorbing significant impacts. To protect the driver's safety, the insulation layer 403 is made of aluminum silicate cotton, a high-quality insulation material with excellent high-temperature resistance and insulation performance. With a thickness of 15mm to 20mm, the insulation layer 403 effectively blocks the transmission of external high temperatures into the control room 2, thereby improving the working environment for operators. The reinforced inner layer 404 is made of glass fiber reinforced plastic, which has advantages such as light weight, high strength, and corrosion resistance. With a thickness of 1mm to 3mm, the reinforced inner layer 404 is strengthened while reducing the weight of the explosion-proof door 4.
