Description
Technical Field
[0001] This utility model relates to the field of excavator technology, specifically a high-power electric explosion-proof excavator. Background Technology
[0002] With increasingly stringent environmental and safety requirements in the construction industry, electric excavators are gradually replacing traditional fuel-powered excavators due to their advantages of zero emissions and low noise. This is especially true in special operational scenarios involving flammable and explosive materials, such as mines, chemical plants, and oil and gas plants, where the demand for high-power electric excavators is becoming increasingly urgent. However, the working environments in these scenarios are complex and harsh, containing not only explosive substances like gas and dust, but also potential hazards such as flying debris and impacts from heavy objects. This places extremely high demands on the explosion-proof and impact-resistant protection performance of the excavator's control room.
[0003] Existing control room glass is mostly installed as a single piece, which makes it difficult to disassemble and install. When the glass is damaged and needs to be replaced, multiple parts often need to be disassembled, which is time-consuming and laborious, affecting work efficiency. In addition, the control room glass of existing electric excavators is mostly made of ordinary tempered glass or simple composite glass, and its installation structure is usually directly bolted or silicone sealed and glued, which has poor explosion-proof performance. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a high-power electric explosion-proof excavator, which can effectively solve the problems in the prior art.
[0005] The technical solution adopted by this utility model is: a high-power electric explosion-proof excavator, including an excavator body and an operating room located on top of the excavator body. An installation frame is embedded in the outer surface of the operating room. An explosion-proof glass is provided on the side of the installation frame away from the operating room. A pressure plate is provided on the side of the explosion-proof glass away from the installation frame. A guide post is fixedly installed on the end of the installation frame near the explosion-proof glass. A positioning hole is opened on the end of the pressure plate near the installation frame. A locking nut that is threadedly connected to the guide post is provided on the side of the pressure plate away from the explosion-proof glass.
[0006] Preferably, the positioning holes are adapted to the guide posts, and the positioning holes and guide posts are provided in four identical sets, with the four sets of positioning holes and guide posts symmetrically distributed on the surface centerline of the mounting frame.
[0007] The above technical solution enables rapid positioning and installation of the clamping plate by matching the positioning holes with the guide posts. Furthermore, by setting four sets of identical positioning holes and guide posts, it ensures that the explosion-proof glass is subjected to uniform force during installation, thereby improving the stability of the overall installation structure.
[0008] Preferably, the explosion-proof glass includes a first tempered glass layer, a metal wire layer is provided at one end of the first tempered glass layer near the mounting frame, and a second tempered glass layer is provided at the end of the metal wire layer away from the first tempered glass layer. The first tempered glass layer, the metal wire layer, and the second tempered glass layer are provided with mounting holes for sliding installation with guide posts at the ends of the first tempered glass layer, the metal wire layer, and the second tempered glass layer near the mounting frame.
[0009] By using the above technical solution and installing explosion-proof glass, the risk of injury from flying stones or fragments can be reduced when operators are using the device, thereby improving their personal safety.
[0010] Preferably, the first tempered glass layer and the second tempered glass layer have grooves on their sides, and a sealing strip is embedded in the inner side of the groove.
[0011] By embedding sealing strips into the side grooves of the first and second tempered glass layers, the sealing performance between the explosion-proof glass and the mounting frame can be effectively improved, preventing dust, moisture, oil, and other contaminants from entering the control room and ensuring a good working environment for operators. At the same time, the sealing strips have a certain degree of elasticity, which can buffer the explosion-proof glass, reduce damage to the glass from rigid impacts, and thus improve the service life of the explosion-proof glass.
[0012] Preferably, the thickness of the first tempered glass layer is 3mm to 10mm, and the thickness of the second tempered glass layer is the same as that of the first tempered glass layer.
[0013] By using the above technical solution, and by setting the first tempered glass layer and the second tempered glass layer to have the same thickness, the overall strength of the explosion-proof glass is improved, ensuring that it can withstand the impact of gravel or hard objects during operation and meet the explosion-proof requirements. At the same time, by setting the thickness of the first tempered glass layer and the second tempered glass layer to be 3mm to 10mm, the increase in glass weight caused by excessive glass thickness can be reduced, thereby reducing the load on the excavator body and reducing production costs.
[0014] Preferably, the metal wire layer is woven from stainless steel wire with a diameter of 0.1 mm to 0.5 mm, and the spacing between two adjacent sets of metal wires is 1 mm to 5 mm.
[0015] Through the above technical solution, the metal wire layer is woven from stainless steel wire. Stainless steel has corrosion resistance and high strength, making it suitable for the harsh outdoor working environment of the excavator body. By spacing the two adjacent sets of metal wires between 1mm and 5mm, the tensile strength of the metal wire layer for the explosion-proof glass is ensured, the overall tear resistance is improved, and thus the explosion-proof performance of the explosion-proof glass is enhanced.
[0016] Preferably, the first tempered glass layer, the second tempered glass layer, and the metal wire layer are all bonded together using PVB adhesive.
[0017] Through the above technical solution, the first tempered glass layer and the second tempered glass layer are bonded to the metal wire layer by a PVB adhesive. The PVB adhesive has excellent adhesion and impact resistance, ensuring the bonding strength between the first tempered glass layer, the second tempered glass layer and the metal wire layer, thereby improving the impact resistance of the explosion-proof glass.
[0018] Compared with the prior art, this utility model provides a high-power electric explosion-proof excavator, which has the following beneficial effects:
[0019] 1. This high-power electric explosion-proof excavator features a sliding installation of the explosion-proof glass via mounting holes and guide columns, enabling rapid connection between the explosion-proof glass and the mounting frame. Subsequently, the positioning holes, matched with the guide columns, facilitate the rapid positioning and installation of the clamping plate. Furthermore, the use of four identical sets of positioning holes and guide columns ensures uniform force distribution on the explosion-proof glass during installation, enhancing the stability of the overall installation structure. Finally, the threaded connection between the locking nut and the guide column further increases the clamping force between the clamping plate and the mounting frame, ensuring the stability of the explosion-proof glass during operation.
[0020] 2. This high-power electric explosion-proof excavator features a three-layer structure for its explosion-proof glass: a first tempered glass layer, a second tempered glass layer, and a metal wire layer. This structure ensures the impact resistance of the explosion-proof glass. By ensuring that the first and second tempered glass layers are of the same thickness, the overall strength of the explosion-proof glass is improved, ensuring that it can withstand the impact of gravel or hard objects during operation and meeting explosion-proof requirements.
[0021] 3. This high-power electric explosion-proof excavator effectively improves the sealing performance between the explosion-proof glass and the mounting frame by embedding sealing strips in the side grooves of the first and second tempered glass layers. This prevents dust, moisture, oil, and other contaminants from entering the control room, ensuring a good working environment for the operators. At the same time, the sealing strips have a certain degree of elasticity, which can buffer the explosion-proof glass, reduce damage to the glass from rigid impacts, and thus improve the service life of the explosion-proof glass.

[0029] 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.
[0030] Example 1:
[0031] like Figure 1-6 As shown, the present invention provides a high-power electric explosion-proof excavator, including an excavator body 1 and an operating room 2 located on top of the excavator body 1. An installation frame 3 is embedded in the outer surface of the operating room 2. An explosion-proof glass 4 is provided on the side of the installation frame 3 away from the operating room 2. A pressure plate 5 is provided on the side of the explosion-proof glass 4 away from the installation frame 3. A guide post 6 is fixedly installed on the end of the installation frame 3 near the explosion-proof glass 4. A positioning hole 7 is opened on the end of the pressure plate 5 near the installation frame 3. A locking nut 8 that is threadedly connected to the guide post 6 is provided on the side of the pressure plate 5 away from the explosion-proof glass 4.
[0032] Specifically, the positioning holes 7 are adapted to the guide posts 6, and four identical sets of positioning holes 7 and guide posts 6 are provided. The four sets of positioning holes 7 and guide posts 6 are symmetrically distributed along the center line of the surface of the mounting frame 3. The advantage is that by adapting the positioning holes 7 and guide posts 6, the clamping plate 5 can be quickly positioned and installed. Furthermore, by setting four identical sets of positioning holes 7 and guide posts 6, it is ensured that the explosion-proof glass 4 is subjected to uniform force during installation, thereby improving the stability of the overall installation structure.
[0033] Example 2:
[0034] like Figure 2-6As shown, as an improvement on the previous embodiment, the explosion-proof performance of the explosion-proof glass 4 is further enhanced. Specifically, the explosion-proof glass 4 includes a first tempered glass layer 401, a wire layer 402 is provided at one end of the first tempered glass layer 401 near the mounting frame 3, and a second tempered glass layer 403 is provided at the end of the wire layer 402 away from the first tempered glass layer 401. Mounting holes 405 are provided at the ends of the first tempered glass layer 401, the wire layer 402, and the second tempered glass layer 403 near the mounting frame 3 for sliding installation with the guide post 6. The advantage is that by providing the explosion-proof glass 4, the risk of injury from flying stones or fragments is reduced when operators are using the device, thereby improving operator safety.
[0035] Specifically, grooves 404 are formed on the sides of the first tempered glass layer 401 and the second tempered glass layer 403, and sealing strips 406 are embedded in the inner side of the grooves 404. The advantage is that by embedding the sealing strips 406 in the grooves 404 on the sides of the first tempered glass layer 401 and the second tempered glass layer 403, the sealing performance between the explosion-proof glass 4 and the mounting frame 3 can be effectively improved, preventing dust, moisture, oil, etc., from entering the interior of the control room 2, ensuring a good working environment for the operators. At the same time, the sealing strips 406 have a certain degree of elasticity, which can buffer the explosion-proof glass 4, reducing damage to the glass from rigid impacts, thereby increasing the service life of the explosion-proof glass 4.
[0036] Specifically, the thickness of the first tempered glass layer 401 is 3mm to 10mm, and the thickness of the second tempered glass layer 403 is the same as that of the first tempered glass layer 401. The advantage is that by setting the thickness of the first tempered glass layer 401 and the second tempered glass layer 403 to be the same, the overall strength of the explosion-proof glass 4 is improved, ensuring that it can withstand the impact of gravel or hard objects during operation, meeting explosion-proof requirements. At the same time, by setting the thickness of the first tempered glass layer 401 and the second tempered glass layer 403 to 3mm to 10mm, the increased weight caused by excessive glass thickness can be reduced, thereby reducing the load on the excavator body 1 and reducing production costs.
[0037] Specifically, the metal wire layer 402 is woven from stainless steel wire with a diameter of 0.1mm to 0.5mm, and the spacing between two adjacent sets of metal wires is 1mm to 5mm. The advantage is that the metal wire layer 402 is woven from stainless steel wire, which has corrosion resistance and high strength, making it suitable for the harsh outdoor working environment of the excavator body 1. The 1mm to 5mm spacing between adjacent sets of metal wires ensures the tensile strength of the metal wire layer 402 for the explosion-proof glass 4, improving the overall tear resistance and thus enhancing the explosion-proof performance of the explosion-proof glass 4.
[0038] Specifically, both the first tempered glass layer 401 and the second tempered glass layer 403 are bonded to the metal wire layer 402 using PVB adhesive. The advantage is that the PVB adhesive, with its excellent adhesion and impact resistance, ensures the bonding strength between the first and second tempered glass layers 401 and the metal wire layer 402, thereby improving the impact resistance of the explosion-proof glass 4.
[0039] Working principle: During use, the explosion-proof glass 4 is slidably installed through the mounting hole 405 and the guide post 6, enabling a quick connection between the explosion-proof glass 4 and the mounting frame 3. Subsequently, the positioning hole 7, which is adapted to the guide post 6, allows for the quick positioning and installation of the clamping plate 5. Furthermore, by setting four sets of identical positioning holes 7 and guide posts 6, it is ensured that the explosion-proof glass 4 is subjected to uniform force during installation, improving the stability of the overall installation structure. Finally, the threaded connection between the locking nut 8 and the guide post 6 further enhances the clamping force between the clamping plate 5 and the mounting frame 3, ensuring the stability of the explosion-proof glass 4 during operation. The explosion-proof glass 4, with its three-layer structure consisting of a first tempered glass layer 401, a second tempered glass layer 403, and a metal wire layer 402, ensures its impact resistance. By setting the first tempered glass layer 401 and the second tempered glass layer 403 to be of the same thickness, the overall strength of the explosion-proof glass 4 is improved, ensuring it can withstand the impact of gravel or hard objects during operation, thus meeting explosion-proof requirements. Simultaneously, by setting the thickness of the first tempered glass layer 401 and the second tempered glass layer 403 to 3mm to 10mm, the increased weight caused by excessive glass thickness is reduced, thereby lightening the load on the excavator body 1 and reducing production costs. To reduce costs, sealing strips 406 are embedded in the side grooves 404 of the first tempered glass layer 401 and the second tempered glass layer 403. This effectively improves the seal between the explosion-proof glass 4 and the mounting frame 3, preventing dust, moisture, oil, and other contaminants from entering the control room 2 and ensuring a good working environment for operators. Simultaneously, the sealing strips 406 have a certain degree of elasticity, which can cushion the explosion-proof glass 4, reducing damage from rigid impacts and thus extending its service life. The metal wire layer 402 is woven from stainless steel wire; stainless steel is corrosion-resistant and has high strength. Suitable for harsh outdoor working environments of excavator body 1, the spacing between two adjacent sets of metal wires is 1mm to 5mm to ensure the tensile strength of the metal wire layer 402 to the explosion-proof glass 4, improve the overall tear resistance, and thus improve the explosion-proof performance of the explosion-proof glass 4. The first tempered glass layer 401 and the second tempered glass layer 403 are bonded to the metal wire layer 402 by PVB adhesive. PVB adhesive has excellent adhesion and impact resistance, ensuring the bonding strength between the first tempered glass layer 401 and the second tempered glass layer 403 and the metal wire layer 402, thereby improving the impact resistance of the explosion-proof glass 4.
