Description

Technical Field

[0001] The invention relates to a protective device and method for a transportable generator, belonging to the technical field of oil and gas field mining equipment. Background Art

[0002] Oilfield vehicles are often used in on-site construction environments with challenging road conditions. As operational requirements become more complex and equipment becomes larger, the space on the platform becomes increasingly limited, making their use and transportation particularly challenging. Furthermore, generators, essential power supply equipment in oilfield environments, require secure and reliable attachment to the vehicle to ensure they meet transportation requirements. Currently, most generators are transported separately on skids or require separate transport, or they occupy separate space on the platform, wasting significant space on the vehicle and reducing space utilization. A few manufacturers place the generators on the bottom of the platform, but this lacks effective protection. Summary of the Invention

Rectangular bends are reserved on the upper and lower sides of the door for installing the gas spring 8 and the limit hooks of the buckle 12. Holes are opened on the top of the left and right sides of the door for installing the nylon camshaft 18 and the locking nut 19. The door can rotate around the nylon camshaft 18. The door is normally closed and has door locks on both sides of the bottom for locking the door. When the generator is in operation, it needs to be opened and the door is flipped up and flattened. The cams of the nylon camshafts 18 on both sides of the door are placed in the slide grooves and roll in the slide grooves 205. After being flattened, the door can be pulled and displaced along the slide grooves. During displacement, the door slides on the nylon rollers to reduce friction resistance and protect the paint surface. The door is pushed to the innermost limit. At this time, the buckle body and the limit hook are aligned and manually locked to ensure that the door is firmly limited.

[0068] The gas spring 8 consists of a pneumatic rod 801, a cylinder 802 and a ball stud 803. The ball studs 803 at both ends are installed between the cylindrical boss of the frame and the box door. When the position of the box door changes, the pneumatic rod is driven to expand and contract and rotate around the bottom ball stud.

[0069] The limit slider 21 is made of polyformaldehyde material, is in the shape of a tailless arrow, and has a countersunk hole. It is fixed to the top of the outer side of the second column through the second connecting piece 22; a protrusion is provided on the back of the limit slider 21, which is embedded in the slide rail groove to block the nylon camshaft 18 and prevent it from falling off; when installed, the tail of the arrow protrudes from the inner edge of the second column to reduce the gap between the box door and the frame.

[0070] The generator exhaust system consists of a chimney frame 23, U-shaped bolts 24, a chimney 25 and a spark catcher 26. One end of the chimney 25 is mounted on the generator chimney of the generator, and the other end is equipped with the spark catcher 26. The chimney frame 23 and U-shaped bolts 24 are used as support in the middle to guide the high-temperature exhaust gas to an open area and ensure that the exhausted exhaust gas does not contain sparks, thereby meeting the explosion-proof requirements of oil and gas fields.

[0071] The present invention realizes reliable fixation and continuous operation under the generator platform, does not occupy the top space of the vehicle upper mounting platform 3, and realizes the consistent height position of the generator. The oil level gauge 6 and the oil supply pipeline 7 are connected to the oil suction pump of the generator to ensure its smooth oil supply; the multi-movable track box door that can be closed and locked, flipped up, and pushed onto the platform is used to ensure its protection of the generator and improve its operating state and heat dissipation state.

[0072] The present invention can provide three states for the generator:

[0073] 1) When transporting the generator, the door is closed and locked to prevent mud and rain splashing from the outside. Its specific position ensures that the vehicle mounting platform 3 on top of the generator is protected from rain. Fenders 4 and fuel tank 5 in the front and rear directions provide shielding, and the semi-enclosed structure protects the generator from corrosion. At this time, the gas spring 8 is slightly compressed, giving the door an outward thrust, ensuring that the door does not shake with the vibration of the vehicle and reducing noise.

[0074] 2) The nylon roller 11 and the door form a rotating shaft, and the baffle formed by the bent plate 211 welded to the frame, so that the door can only be flipped upward from the vertical locked state. During operation, the door is flipped upward, and the outward thrust of the gas spring supports the low-weight aluminum alloy door, preventing it from falling and closing without external force, thus providing sun and rain protection for the generator.

[0075] 3) Because the cam on the outside of the nylon camshaft 18 is placed in the slide groove, the cam can roll in the slide groove, so that the door can be pushed and pulled along the slide groove after it is flipped up and leveled. During displacement, the door slides on the nylon roller to reduce friction resistance and protect the paint surface. The gas spring provides outward thrust in the first half of the push stroke to ensure that the force on both sides is even. The limit sliders on both sides ensure that the door moves parallel to the slide groove without deflection or jamming. The gas spring extends outward to the vertical slide groove track section, which provides outward thrust to ensure that the door is not slightly bumped or gusted. Push and apply the operator's thrust feel. When the pneumatic rod is extended inward from the vertical state, an inward and upward thrust is applied to the box door, causing the box door to automatically retract until the nylon cam shaft 18 slides along the slide groove to the limit position blocked by the door-shaped angle steel frame. At this time, the buckle body of the box door and the limit hook are aligned, and manually locked to ensure that the box door is firmly limited. At this time, the gas spring remains in a slightly compressed state, maintaining a certain thrust on the box door to prevent the box door from extending out of the vehicle due to vibration or other reasons when the box door is forgotten to be closed or manually locked.

[0076] The generator 1 is not specified to a specific model, and any size and specification that ensures ground clearance meets the conditions for safe transportation of the vehicle can be used. The bracket 16 at the bottom of the frame 2 can be welded according to the position of the reserved mounting hole of the generator 1.

[0077] The connecting plate 1 and the connecting plate 2 are connected with the vehicle C-beam bolts. The multiple circular holes on the connecting plate 2 are spaced at equal widths with the bolt holes reserved in the vehicle beam. The connecting plate 1 is placed at a relatively far distance on both sides. Its transverse waist holes can avoid the misalignment of the bolt holes reserved in the vehicle beam, resulting in mismatched bolt holes.

[0078] The nylon roller supports the door during the process of pushing and pulling the door, and its rolling structure converts sliding friction into rolling friction, thereby reducing damage to the door and reducing frictional resistance.

[0079] The protrusion on the back of the limit slider can be embedded in the slide rail groove, blocking the nylon cam shaft 18 to prevent it from falling out, and ensuring that the nylon cam shaft 18 is pulled out to the maximum distance and closed just close to the right-angle inner groove of the bending plate to limit the position, reducing the amount of movement; when installed, the tail of the arrow protrudes from the second inner edge of the column, reducing the gap between the box door and the frame, and reducing the left and right displacement of the box door; the limit slider is softer than the box door, and colliding with it can protect the box door from deformation and damage; its good self-lubrication ensures smooth guidance; when the box door needs to be disassembled, the limit slider can be removed and pulled out for replacement or maintenance.

[0080] The present invention has five main advantages: 1. It has low cost, and the installation position can be adjusted according to the different installation sizes of the generator, and it does not occupy the working space of personnel or equipment on both sides of the vehicle; 2. Under the premise of ensuring its reliable fixation, it not only meets the requirement that the vehicle width of the working vehicle does not exceed the national standard, but also reduces the cost and time loss of disassembly and use; 3. The installation position is flush with the chassis fuel tank, and the generator can be modified to be supplied with oil by the chassis fuel tank, avoiding the labor intensity of frequent refueling due to a small tank and the risk of shutdown caused by lack of oil; 4. The generator box door can be flipped up to provide sun and rain protection, and can be pushed into the platform after being flattened to avoid the space on the side of the vehicle; 5. On the premise of providing protection for the generator, the heat dissipation, smoke exhaust, fire prevention and waterproofing effects are improved.
