Description

Technical Field

[0001] This invention belongs to the field of electric injection pump technology, specifically an electric injection pump with shock absorption and explosion-proof effects. Background Technology

[0002] In equipment maintenance within industries such as oil, gas, and chemicals, the sealing performance of valves and piping systems is crucial. To ensure effective sealing, cleaning fluid or sealing grease is typically injected into the valve cavity, a process usually requiring grease injection tools. Currently, commonly used grease injection equipment falls into three main categories: manual grease guns, pneumatic grease guns, and ordinary electric grease guns. These three types of grease guns employ different pressurization methods to inject cleaning fluid or sealing grease into the target area, thereby improving valve sealing and extending equipment lifespan.

[0003] In the prior art, an explosion-proof electric injection pump with publication number CN120521134A uses a dual-piston pressurization structure within the grease injection gun body. This involves improving the piston assembly inside the grease injection gun body by adopting a dual-piston series design. The high-pressure oil output from the hydraulic pump first pushes the first piston, and then, through a linkage structure, drives the second piston for secondary pressurization, significantly increasing the grease injection pressure to meet the requirements of high-pressure grease injection conditions. Furthermore, the coordinated work of the two pistons makes the grease injection flow rate more stable. However, the following problems still exist: The aforementioned electric injection pump uses a dual-piston pressurization structure within the grease gun body, which works together to make the grease injection flow more stable. However, it is prone to generating electric arcs or high temperatures during operation, which can lead to explosions. The aforementioned explosion-proof battery box lacks an effective protective structure. Furthermore, existing electric or pneumatic injection pumps generate continuous mechanical vibration in their power units during operation. During movement and transportation, the equipment is also subjected to random bumps and impacts, and the vibration can easily lead to fatigue damage to structural components. Summary of the Invention

[0004] (a) Technical problems to be solved In view of the shortcomings of the existing technology, and to solve the problems that the explosion-proof battery box of the above-mentioned electric injection pump lacks an effective protective structure and that vibration can easily cause fatigue damage to the structural components, this invention proposes an electric injection pump with shock absorption and explosion-proof effect.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: an electric injection pump with shock absorption and explosion-proof effect, comprising a shock absorption mechanism, a support mechanism disposed on top of the shock absorption mechanism, and an explosion-proof mechanism located on the front side of the top of the support mechanism. The explosion-proof mechanism includes an explosion-proof battery box, which adopts a three-layer composite structure. The inner layer of the explosion-proof battery box is provided with a stainless steel sealing layer, and the inner side of the stainless steel sealing layer is coated with a flame-retardant insulating coating. The middle layer of the explosion-proof battery box has a honeycomb heat dissipation channel, and the inside of the honeycomb heat dissipation channel is provided with high thermal conductivity silicone grease. Explosion-proof filters are provided at both ends of the honeycomb heat dissipation channel. The outer layer of the explosion-proof battery box is provided with a plurality of aluminum alloy heat dissipation fins, and the plurality of aluminum alloy heat dissipation fins are connected to the honeycomb heat dissipation channel.

[0006] In the above scheme, the core of the explosion-proof mechanism is the explosion-proof battery box, which adopts a three-layer composite structure design to form all-round explosion-proof protection. The inner layer is equipped with a stainless steel sealing layer, and the inner side of the stainless steel sealing layer is coated with a flame-retardant insulating coating, which provides double protection to block the internal electric arc and high temperature from being conducted outward, while preventing the intrusion of external flammable and explosive media. The middle layer has a honeycomb heat dissipation channel, which is filled with high thermal conductivity silicone grease, which can quickly conduct the heat generated inside the box. Explosion-proof filters are set at both ends of the channel to ensure heat dissipation and ventilation while intercepting flammable and explosive gases or dust from entering the box. The outer layer is equipped with several aluminum alloy heat dissipation fins, which are connected to the honeycomb heat dissipation channel and have anodized surfaces to further improve heat dissipation efficiency and quickly dissipate the heat conducted by the channel to the outside.

[0007] Preferably, the explosion-proof battery box has an explosion-proof diaphragm inside its outer shell, the explosion-proof diaphragm being connected to a honeycomb heat dissipation channel, and a pressure relief valve being provided at the rear of the explosion-proof battery box for releasing pressure inside the box.

[0008] In the above solution, when the pressure inside the box rises due to increased temperature, the explosion-proof diaphragm absorbs part of the pressure through elastic deformation, preventing the box shell from deforming due to pressure impact and damaging the sealing performance; a pressure relief valve is provided at the rear of the explosion-proof battery box. When the pressure inside the box exceeds a preset threshold, the explosion-proof diaphragm triggers the pressure relief valve to open, quickly releasing the internal pressure and fundamentally eliminating the risk of explosion.

[0009] Preferably, the shock absorption mechanism includes a shock absorption base, with movable plates hinged to both the front and rear sides of the shock absorption base. Fixed insertion holes are provided on both the front and rear sides of the movable plates. Fixed insertion rods that are compatible with the fixed insertion holes are inserted into both the front and rear sides of the shock absorption base. Through the cooperation between the fixed insertion rods and the fixed insertion holes, the movable plates can be fixed and opened / closed, which facilitates the installation and maintenance of the equipment.

[0010] Preferably, the shock-absorbing base is fixedly connected to shock-absorbing components in all directions, and each shock-absorbing component includes a first support plate. A second support plate is provided at the bottom of the first support plate. A plurality of composite steel wire ropes are provided between the first support plate and the second support plate. When the equipment vibrates, the first support plate and the second support plate are squeezed relative to each other, and the composite steel wire ropes deform to generate damping force and consume vibration energy.

[0011] Preferably, the bottom left and right sides of the second support plate are fixedly connected to support columns, each support column is provided with a support spring inside, and each support spring is provided with a limit post at its top. The limit post is elastically connected to the support column through the support spring and is fixedly connected to the first support plate. The support spring generates a reverse elastic force through elastic deformation, which cancels out the vibration energy and further enhances the shock absorption effect.

[0012] Preferably, a first support rod is provided on each of the two opposing sides of the limiting posts. The first support rod is movably pinned to the first support plate. A second support rod is provided below the first support rod and is movably pinned to the second support plate. A hollow shaft is provided between the first and second support rods. The hollow shaft is used for inserting a limiting screw. When the equipment needs to be transported and fixed or to perform high-precision operations, the limiting screw is inserted into the hollow shaft to fix the first and second support rods, thereby locking the relative position of the first and second support plates and improving the overall rigidity of the equipment.

[0013] Preferably, a fixed seat is fixedly connected to each of the four corners of the bottom of the shock-absorbing base, a damper is fixedly connected to the inner top of each fixed seat, a shock-absorbing plate is provided on the outside of the damper, and a support wheel is fixedly connected to the bottom of the damper. The support wheel facilitates the movement of the equipment. During transportation, the bumps and impacts received by the support wheel are absorbed layer by layer by the buffering effect of the damper and the shock-absorbing effect of the shock-absorbing plate, thereby reducing vibration damage during transportation.

[0014] Preferably, the support mechanism includes a support base, which is fixedly connected to a first support plate. A fixed bracket is fixedly connected to the top of the support base. The left side of the fixed bracket is fixedly connected to an explosion-proof battery box. A telescopic pull rod is fixedly connected to the right side of the support base. Together with the support wheels at the bottom, it is convenient for the operator to pull the equipment to move, thereby improving the portability of the equipment. A grease injection gun body is provided on the front side between the explosion-proof battery box and the telescopic pull rod.

[0015] Preferably, the bottom end cap of the grease injection gun is connected to the side oil outlet of the hydraulic pump via a pipeline, and the top of the grease injection gun is connected to a pressure gauge via an adapter. The pressure gauge can display the pressure value in real time during the grease injection process, which is convenient for operators to monitor the operation status and avoid equipment damage or seal failure due to abnormal pressure. The grease injection gun is connected to a high-pressure hose to the large-end nozzle via a T-connector. The high hydraulic pressure provided by the hydraulic pump pushes the piston inside the grease injection gun to deliver cleaning fluid or sealing grease into the valve cavity. When the hydraulic pump is running, it pressurizes the hydraulic oil in the oil tank and delivers it to the grease injection gun, pushing the piston inside the grease injection gun to move, thereby stably delivering the cleaning fluid or sealing grease into the valve cavity.

[0016] Preferably, an end cap tightening detection rod is provided on the right side of the top end cap of the grease injection gun body, which can detect the tightening status of the end cap in real time, ensure the sealing performance of the grease injection gun body, and avoid medium leakage during the grease injection process. An explosion-proof motor is provided at the rear of the grease injection gun body. The explosion-proof motor is connected to the explosion-proof battery box via a cable and is powered by the explosion-proof battery box. The explosion-proof design of the explosion-proof motor works in conjunction with the explosion-proof battery box to further improve the overall explosion-proof level of the equipment. An oil tank is provided between the grease injection gun body and the explosion-proof motor. The oil tank is used to provide a power source for the hydraulic system.

[0017] (III) Beneficial Effects Compared with the prior art, the present invention provides an electric injection pump with shock absorption and explosion protection effects, which has the following beneficial effects: 1. When using the explosion-proof battery box, the present invention achieves heat dissipation by anodizing the surface of the aluminum alloy heat sink fins. The explosion-proof filter prevents flammable and explosive gases from entering. When the pressure inside the explosion-proof battery box rises due to temperature increase, the explosion-proof diaphragm elastically deforms to absorb the pressure, preventing the shell from deforming and damaging the seal. When the pressure exceeds the threshold, the explosion-proof diaphragm triggers the pressure relief valve to release the pressure, thus solving the problem of the lack of an effective protective structure in the explosion-proof battery box of the electric injection pump.

[0018] 2. This invention generates damping force by compressing the first and second support plates, causing the composite wire rope to be compressed. The elastic potential energy generated by the support spring is used to cancel out the energy generated by vibration, thus achieving shock absorption. The limiting screw is inserted into the hollow shaft to fix the first and second support rods together, which is convenient for transportation and fixed or for delicate operations that require extremely high rigidity support. The support wheel compression damper, together with the shock absorber, realizes the shock absorption operation during transportation, solving the problem that vibration can easily lead to fatigue damage to structural components.

[0019] 3. This invention uses a pressure gauge to detect the pressure during the grease injection process, allowing operators to view the pressure value in real time. The end cap tightening detection rod is used to check whether the top end cap of the grease injection gun is tightened properly, ensuring the sealing performance of the grease injection gun. The operation of the hydraulic pump can pressurize the hydraulic oil in the oil tank and deliver it to the grease injection gun to push the piston inside the cylinder, solving the problem of injecting cleaning fluid or sealing grease.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-10 The present invention provides an electric injection pump with shock absorption and explosion protection effect, including a shock absorption mechanism 1, a support mechanism 2 disposed on the top of the shock absorption mechanism 1, and an explosion protection mechanism 3 located on the front side of the top of the support mechanism 2.

[0025] like Figure 1 , Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 9 As shown, the explosion-proof mechanism 3 includes an explosion-proof battery box 301. The explosion-proof battery box 301 adopts a three-layer composite structure. The inner layer of the explosion-proof battery box 301 is provided with a stainless steel sealing layer 302, and the inner side of the stainless steel sealing layer 302 is coated with a flame-retardant insulating coating. The middle layer of the explosion-proof battery box 301 has a honeycomb heat dissipation channel 303. The honeycomb heat dissipation channel 303 is filled with high thermal conductivity silicone grease. Explosion-proof filters are provided at both ends of the honeycomb heat dissipation channel 303. The outer layer of the explosion-proof battery box 301 is provided with a number of aluminum alloy heat dissipation fins 306, which are connected to the honeycomb heat dissipation channel 303. An explosion-proof diaphragm 305 is provided inside the outer shell of the explosion-proof battery box 301, which is connected to the honeycomb heat dissipation channel 303. A pressure relief valve 307 is provided at the rear of the explosion-proof battery box 301 for releasing the pressure inside the box.

[0026] The above solution involves anodizing the surface of the aluminum alloy heat sink 306 when using the explosion-proof battery box 301, using an explosion-proof filter to prevent flammable and explosive gases from entering, and using the explosion-proof diaphragm 305 to absorb the pressure due to the increased temperature inside the explosion-proof battery box 301 to prevent the shell from deforming and damaging the seal. When the pressure exceeds the threshold, the explosion-proof diaphragm 305 triggers the pressure relief valve 307 to release the pressure.

[0027] like Figure 1, Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 10 As shown, the shock absorption mechanism 1 includes a shock absorption base 101. Movable plates 102 are hinged to both the front and rear sides of the shock absorption base 101. Fixed insertion holes are provided on both the front and rear sides of the movable plates 102. Fixed insertion rods 103, matching the fixed insertion holes, are inserted into both the front and rear sides of the shock absorption base 101. Shock absorption components are fixedly connected to the front, rear, left, and right sides inside the shock absorption base 101. Each shock absorption component includes a first support plate 104. A second support plate 105 is provided at the bottom of the first support plate 104. Several composite steel wire ropes 106 are arranged between the first support plate 104 and the second support plate 105. Supporting bottom columns 107 are fixedly connected to the left and right sides of the bottom of the second support plate 105. A supporting spring 108 is provided inside each supporting bottom column 107. A limiting post 109 is provided at the top of each supporting spring 108. The limiting post 109 is connected to the supporting spring 108 via the limiting spring 108. 8 is elastically connected to the support base column 107, and the limiting column 109 is fixedly connected to the first support plate 104. A first support rod 1010 is provided on the opposite side of the two limiting columns 109. The first support rod 1010 is movably pinned to the first support plate 104. A second support rod 1011 is provided below the first support rod 1010. The second support rod 1011 is movably pinned to the second support plate 105. A hollow shaft 1012 is provided between the first support rod 1010 and the second support rod 1011. The hollow shaft 1012 is used for the insertion of the limiting screw. Fixed seats 1013 are fixedly connected to the four corners of the bottom of the shock-absorbing base 101. A damper 1014 is fixedly connected to the top of the inner part of each fixed seat 1013. A shock-absorbing plate 1015 is provided on the outside of the damper 1014. A support wheel 1016 is fixedly connected to the bottom of the damper 1014.

[0028] The above scheme involves compressing the first support plate 104 and the second support plate 105 to generate damping force in the composite wire rope 106. Simultaneously, since the limiting post 109 is elastically connected to the supporting bottom post 107 through the supporting spring 108, the elastic potential energy generated by the supporting spring 108 cancels out the energy generated by the vibration, thus completing the shock absorption operation. The limiting screw is inserted into the hollow shaft 1012 to fix the first support rod 1010 and the second support rod 1011 together, which is convenient for transportation and fixation or for delicate operations that require extremely high rigidity support. During transportation, the support wheel 1016 compresses the damper 1014 in conjunction with the shock absorber 1015 to achieve shock absorption during transportation.

[0029] like Figure 1 , Figure 3 , Figure 7 and Figure 8As shown, the support mechanism 2 includes a support base 201, which is fixedly connected to the first support plate 104. A fixed bracket is fixedly connected to the top of the support base 201. The left side of the fixed bracket is fixedly connected to the explosion-proof battery box 301. A telescopic rod 208 is fixedly connected to the right side of the support base 201. A grease injection gun body 202 is provided on the front side between the explosion-proof battery box 301 and the telescopic rod 208. The bottom end cap of the grease injection gun body 202 is connected to the side oil outlet of the hydraulic pump 207 through a pipeline. A pressure gauge 20 is connected to the top of the grease injection gun body 202 through an adapter. 4. The grease injection gun body 202 is connected to a high-pressure hose to the large-head nozzle via a three-way quick connector. The high hydraulic pressure provided by the hydraulic pump 207 pushes the piston inside the grease injection gun body 202 to deliver cleaning fluid or sealing grease into the valve chamber. An end cap tightening detection rod 203 is provided on the right side of the top end cap of the grease injection gun body 202. An explosion-proof motor 206 is provided at the rear of the grease injection gun body 202. The explosion-proof motor 206 is connected to the explosion-proof battery box 301 via a cable. An oil tank 205 is provided between the grease injection gun body 202 and the explosion-proof motor 206. The oil tank 205 is used to provide a power source for the hydraulic system.

[0030] The above scheme is as follows: pressure gauge 204 is used to detect the pressure during the grease injection process, so that the operator can check the pressure value in real time; end cap tightening detection rod 203 is used to detect whether the top end cap of the grease injection gun body 202 is tightened in place, so as to ensure the sealing performance of the grease injection gun; and the operation of hydraulic pump 207 can pressurize the hydraulic oil in oil tank 205 and deliver it to grease injection gun body 202 to push the piston inside the cylinder.

[0031] Working principle: In actual use, firstly, pressure gauge 204 is used to detect the pressure during the grease injection process, so that the operator can check the pressure value in real time. The end cap tightening detection rod 203 is used to detect whether the top end cap of the grease injection gun body 202 is tightened in place, ensuring the sealing performance of the grease injection gun. The hydraulic pump 207 is operated to pressurize the hydraulic oil in the oil tank 205 and deliver it to the grease injection gun body 202 to push the piston inside the cylinder.

[0032] Secondly, by squeezing the first support plate 104 and the second support plate 105, the composite wire rope 106 is squeezed to generate damping force. At the same time, the elastic potential energy generated by the support spring 108 is used to cancel out the energy generated by the vibration, thus completing the shock absorption operation. The limit screw is inserted into the hollow shaft 1012 to fix the first support rod 1010 and the second support rod 1011 together, so as to facilitate transportation and fixation or delicate operations that require extremely high rigidity support. During transportation, the support wheel 1016 squeezes the damper 1014 in conjunction with the shock absorber 1015 to realize the shock absorption operation during transportation.

[0033] Finally, when using the explosion-proof battery box 301, the surface of the aluminum alloy heat sink 306 is anodized. The explosion-proof filter prevents flammable and explosive gases from entering. When the pressure inside the explosion-proof battery box 301 rises due to temperature increase, the explosion-proof diaphragm 305 elastically deforms to absorb the pressure, preventing the shell from deforming and damaging the seal. When the pressure exceeds the threshold, the explosion-proof diaphragm 305 triggers the pressure relief valve 307 to release the pressure.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
