Embodiment
[0016] The present invention will be further described below in conjunction with the accompanying drawings: As Figures 1 to 7 shown, a prefabricated multi-functional operation platform for a beam pumping unit includes a rear operation platform 1, a speed reducer operation platform 2, a tripod operation platform 3 and a crossbeam operation platform 4. Among them, the rear operation platform 1 is located on the side plate of the cylinder body 5 at the bottom of the speed reducer 6 and is used when performing operations such as adjusting the balance of the pumping unit or replacing the balance weight. The speed reducer operation platform 2 is located in the middle of the cylinder body 5, and one can stand on the upper part of the speed reducer operation platform 2 when repairing the speed reducer. The tripod operation platform 3 is located on the tripod of the pumping unit and is used when repairing the tripod of the pumping unit. The crossbeam operation platform 4 is located on the crossbeam of the pumping unit, and one stands on its upper part when operating on the tail end of the beam of the pumping unit.
[0017] The rear operation platform 1 includes an upper platform 11, and the upper platform 11 is welded to one side of the cylinder body 5. The bottom of the upper platform 11 is connected to a telescopic pull rod 12. The pull rod 12 is located in a sealed oil passage, which can ensure lubrication and corrosion prevention, and there is no need for separate maintenance. The pull rod 12 is connected to a lower platform 13, so that the lower platform 13 can extend or retract. When the lower platform 13 extends, the area of the overall platform is increased by nearly twice. Inner limit blocks 14 and outer limit blocks 15 are respectively fixed on the upper platform 11. The inner limit block 14 is used for limiting when the lower platform 13 retracts, and the outer limit block 15 is used for limiting when the lower platform 13 extends, to prevent the lower platform 13 from falling. This pull-out structure of the rear operation platform 1 increases the platform area during stretching, making it safer for workers to stand, and retracts when not in use, saving space. At the same time, the edges of the upper platform 11 and the lower platform 13 are made into rounded corners to avoid personal injury caused by bumping when workers are working on the ground.
[0018] The reduction gear operating platform 2 includes a fixed platform 22 which is located inside the cylinder body 5 and welded to the cylinder body 5. Two groups of reduction gear platform tie rods 24 are connected to the fixed platform 22. Grease can be injected into the reduction gear platform tie rods 24 from the outside of the cylinder body 5 to ensure lubrication and anti-corrosion. The two groups of tie rods are respectively connected to the first reduction gear platform 21 and the second reduction gear platform 23. Transverse grooves are formed in the cylinder body 5. The first reduction gear platform 21 and the second reduction gear platform 23 respectively stretch towards the front and rear sides of the cylinder body 5. After stretching, they can extend out from the transverse grooves on the cylinder body 5. After retracting, they are respectively located above and below the fixed platform 22. Limit blocks are also provided on the fixed platform 22 for inner and outer side limiting of the first reduction gear platform 21 and the second reduction gear platform 23. The reduction gear operating platform 2 makes full use of the internal space of the cylinder body 5. When not in use, the operating platform is hidden inside the cylinder body. When in use, the first reduction gear platform 21 and the second reduction gear platform 23 on both sides are pulled out. At the same time, extension platforms are respectively provided at the bottoms of the first reduction gear platform 21 and the second reduction gear platform 23 and can be unfolded to both sides after being pulled out, further increasing the platform area. The size of the operating platform is determined according to the size of the machine type. At the same time, to ensure operation safety, a folding guardrail can be provided on the bracket outside the cylinder body. The guardrail is opened when the platform is in use and can also be retracted when the platform is retracted.
[0019] The tripod operating platform 3 includes a tripod fixed platform 31 which is welded to the pumping unit tripod. A push-pull rod is provided at the bottom of the tripod fixed platform 31. An extension platform 32 is connected to the rod. After the extension platform 32 extends out, its end is lapped on the top of the reduction gear 6, thereby increasing the area of the tripod operating platform 3. Moreover, the extension platform 32 is supported by the reduction gear 6, which also increases the stability. The tripod upper platform 33 is fixed on the top of the tripod fixed platform 31. The area of the tripod upper platform 33 is smaller than that of the tripod fixed platform 31, which is equivalent to increasing the height of the platform. When repairing the pumping unit tripod, one can stand on the tripod fixed platform 31. When repairing the top of the tripod or the walking beam, one can stand on the tripod upper platform 33. When operating, a safety belt suspension anchoring ring needs to be installed at the top of the pumping unit tripod. The operator wears a safety belt and hangs it on the anchoring ring to ensure safety.
[0020] The crossbeam operating platform 4 includes an inverted U-shaped suspension frame 42. During use, the crossbeam operating platform 4 can be suspended on the pumping unit crossbeam through the U-shaped suspension frame 42 and can be removed when not in use to avoid loss. The left and right sides of the suspension frame 42 are respectively connected to a left pedal 41 and a right pedal 43. The two pedals are respectively connected to the suspension frame 42 through pedal rotating shafts 46, enabling them to be folded upward or opened downward. Folding pin holes and opening pin holes are respectively formed in the left pedal 41, and locking holes corresponding to the folding pin holes and opening pin holes are respectively formed in the suspension frame 42. When the left pedal 41 is folded upward and retracted, the folding pin hole aligns with the folding locking hole on the suspension frame 42, and a through pin is inserted into the hole to fix the left pedal 41, saving space and facilitating carrying. When the crossbeam operating platform 4 needs to be used, first remove the through pin. When the left pedal 41 is opened downward, the opening pin hole aligns with the opening locking hole on the suspension frame 42, and then insert the through pin into the hole to fix the pedal and lock the position, increasing the operation safety. The operation of the right pedal 43 is the same as that of the left pedal 41.
[0021] One side of the bottom of the suspension frame 42 is connected to a lock piece 47 through a lock piece rotating shaft, and the other side is connected to a lock catch 45 that cooperates with the lock piece 47. When the suspension frame 42 is suspended on the crossbeam, it is locked by the lock piece 47 to prevent it from falling off the crossbeam. At the same time, safety belt hanging holes are provided on the left and right pedals on both sides. When personnel stand on the footrests to operate, they need to wear safety belts.
[0022] The beam pumping unit adds the above-mentioned operating platform using the original space, increasing the operating platform area while ensuring the operating space, making the operation more convenient and improving the operation safety. At the same time, the rear operating platform 1, the gearbox operating platform 2, and the tripod operating platform 3 are welded to the pumping unit, making it more stable, safe, and theft-proof. The crossbeam operating platform 4 can be removed and taken away when not in use to avoid loss.
