Description
Technical Field
[0001] The utility model relates to the technical field of sprocket adjustment frame equipment, in particular to a sprocket adjustment frame on an oil pumping unit. Background Art
[0002] A pumping unit is a machine for extracting oil, commonly known as a "kowtow machine". The pumping unit is the most important lifting equipment in a rod pumping system. Depending on whether there is a walking beam, it can be divided into a walking beam pumping unit and a non-walking beam pumping unit. The basic characteristics of a walking beam pumping unit are simple structure, easy manufacturing, and convenient use. In particular, it can operate in oil fields around the clock for a long time and is reliable to use. Therefore, although it has disadvantages such as large acceleration of the donkey head suspension point movement, poor balance effect, low efficiency, large size and bulkiness at long strokes, it is still the most widely used pumping unit. The working principle of a walking beam pumping unit is: the power is supplied by a power machine, and the high-speed rotation of the power machine is converted into a low-speed rotation of the pumping unit crank through a reducer, and the rotational motion is converted into up and down reciprocating motion of the pumping unit donkey head by the crank-connecting rod-walking beam mechanism, which drives the deep well pump to work through the suspension rope assembly.
[0003] The sprocket adjustment frame on the oil pumping unit is a device used to adjust the position of the sprocket. It is usually composed of a bracket and an adjusting device. The bracket is used to support and fix the sprocket, and the adjusting device is used to adjust the position of the sprocket. The main use of the sprocket adjustment frame on the oil pumping unit is to adjust the position of the sprocket to ensure the normal operation of the oil pumping unit. Specifically, it can help adjust the horizontality and verticality of the sprocket to adapt to different well conditions and operating requirements of the oil pumping unit. In addition, the sprocket adjustment frame on the oil pumping unit can also reduce the labor intensity of the staff and improve work efficiency. In the process of adjusting the sprocket, the staff can easily move and fix the sprocket by using the adjustment frame to avoid errors and dangers that may occur during manual operation. By using the sprocket adjustment frame on the oil pumping unit, the position of the sprocket can be effectively adjusted to ensure the normal operation of the oil pumping unit. This equipment is generally suitable for various types of oil pumping units, including walking beam and non-walking beam oil pumping units.
[0004] However, in the prior art, some sprocket adjustment frames are used to adjust the height by means of a screw rod. Although fine-tuning by means of the screw rod is very accurate and stable, when the sprocket is to be disassembled, the screw rod needs to be adjusted to lower the sprocket and separate it from the chain, which is inconvenient in practice and cannot be disassembled quickly. In addition, when the sprocket is engaged and connected with the chain, it needs to be adjusted manually continuously, resulting in high labor costs. Utility Model Content
[0005] Based on this, the purpose of the utility model is to provide a sprocket adjustment frame on an oil pumping unit to solve the problem that in the prior art, some sprocket adjustment frames are adjusted in height by a screw rod. Although fine-tuning by the screw rod is very precise and stable, if it is to be disassembled, it is necessary to adjust the screw rod to lower the sprocket and separate it from the chain, which is inconvenient in practice and cannot be disassembled quickly. Moreover, when the sprocket and the chain are engaged and connected, they need to be adjusted manually and continuously, resulting in high labor costs. Technical problems.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a sprocket adjustment frame on an oil pumping unit, comprising a sprocket body, an output shaft is fixedly installed on the sprocket body, and a fixed block is rotatably connected to the outer side of the output shaft, and the bottom of the fixed block is fixedly connected to a fixing rod, and the bottom of the fixing rod is movably connected to a working block, and a screw rod is fixedly installed on the bottom of the working block, and a limit rod is slidably connected inside the screw rod, and the bottom of the limit rod is fixedly connected to a base, and support plates are fixedly installed on both sides of the top of the base with a symmetrical structure, and a balance plate is fixedly connected to the top of the support plate, the screw rod can movably pass through the balance plate, and the top of the balance plate is rotatably connected to a screw sleeve used in conjunction with the screw rod, an air cavity is opened in the working block, and an air inlet and an exhaust port are respectively opened at two ends of the working block, and a blocking block is fixedly connected to the bottom of the fixing rod, and the blocking block is located inside the working block and fits with the inside of the working block.
[0007] By adopting the above technical scheme, when the sprocket position needs to be adjusted during use, the screw rod can be moved upwards through the cooperation between the screw sleeve and the screw rod, so as to flexibly adjust the position of the sprocket. Then, when it is necessary to disassemble it, the gas in the working block can be quickly discharged through the exhaust port, so that the fixing rod can be quickly lowered, so that the sprocket can be quickly separated from the chain, thereby achieving the effect of quickly disassembling the sprocket. The working block is inflated through the air inlet during installation, and then the fixing block is lifted by the cooperation between the blocking block and the fixing rod. This structure can solve the problem in the prior art that some sprocket adjustment frames are adjusted in height by a screw rod. Although fine-tuning by the screw rod is very accurate and stable, if it is disassembled, it is also necessary to adjust the screw rod to make the sprocket descend and separate from the chain, which is inconvenient in practice and cannot be disassembled quickly. Technical problems.

[0009] By adopting the above technical scheme, the air guide block is fixed on both sides of the sprocket body through the cooperation between the connecting rod and the balance plate, and then the connecting rod and the extrusion block cooperate with each other to squeeze the gas in the air storage box, so that the air bag in the clamping block expands rapidly. When the air bag expands, the sprocket and the chain can be initially clamped and limited, so that the chain will not deviate during installation and debugging, and the effect of continuous manual adjustment and support can be avoided, thereby improving the practicality of the sprocket adjustment frame on the entire oil pump.
[0010] The utility model is further configured that the protrusion is fixed to two sides of the working block, and the connecting rod can movably pass through the protrusion, and a locking block used in conjunction with the connecting rod is movably installed in the protrusion.
[0011] By adopting the above technical solution, the connecting rod can be limited and unlocked through the cooperation between the protrusion and the locking block. When the working block moves upward, the connecting rod is fixed in the protrusion by the locking block, so that the connecting rod and the extrusion block can squeeze the gas in the air storage box, thereby expanding the airbag. When the sprocket and the chain are installed, the connecting rod is unlocked by the locking block, and then the connecting rod is moved downward, so that the gas in the airbag is recovered into the air storage box for use.
[0012] The utility model is further configured such that the support plate and the connecting rod are respectively in an eight-shaped structure and an inverted eight-shaped structure, the clamping block is a U-shaped structure, and the sprocket body is located in the middle of the clamping block.
[0013] By adopting the above technical solution, when the support plate and the connecting rod are respectively an eight-shaped and an inverted eight-shaped structure, the stability of the sprocket adjustment frame on the entire oil pump can be improved. Secondly, when the sprocket body is located in the middle position of the clamping block, the air bag can be used to better limit and clamp the sprocket body.

[0015] 1. The utility model can make the screw rod move upward through the mutual cooperation between the screw sleeve and the screw rod, so as to flexibly adjust the position of the sprocket. Then, when it is necessary to disassemble it, the gas in the working block can be quickly discharged through the exhaust port, so that the fixing rod can be quickly lowered, so that the sprocket can be quickly separated from the chain, so as to achieve the effect of quickly disassembling the sprocket. The air in the working block is inflated through the air inlet during installation, and then the fixing block is lifted through the mutual cooperation between the blocking block and the fixing rod. This structure can solve the problem that some sprocket adjustment frames in the prior art are adjusted in height by screw rods. Although fine-tuning by screw rods is very accurate and stable, if it is disassembled, it is necessary to adjust the screw rod to make the sprocket drop and separate from the chain, which is inconvenient in practice and cannot be disassembled quickly.
[0016] 2. The utility model fixes the air guide block on both sides of the sprocket body through the mutual cooperation between the connecting rod and the balance plate, and then the connecting rod and the extrusion block cooperate with each other to squeeze the gas in the air storage box, so that the air bag in the clamping block expands rapidly. When the air bag expands, the sprocket and the chain can be initially clamped and limited, so that the chain will not deviate during installation and debugging and the engagement of the chain, and the effect of continuous manual adjustment and support can be avoided, so that the practicality of the sprocket adjustment frame on the entire oil pump is improved.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0025] The following describes an embodiment of the utility model based on its overall structure.

[0027] When in use, when the position of the sprocket body 1 needs to be adjusted, the screw rod 4 can be moved upward through the cooperation between the screw sleeve 11 and the screw rod 4, so as to flexibly adjust the position of the sprocket body 1. Then, when it is necessary to disassemble it, the gas in the working block 10 can be quickly discharged through the exhaust port 17, so that the fixing rod 23 can be quickly lowered, so that the sprocket body 1 can be quickly separated from the chain, thereby achieving the effect of quickly disassembling the sprocket body 1. The air in the working block 10 is inflated through the air inlet 9 during installation, and then the fixing block 13 is lifted through the cooperation between the blocking block 22 and the fixing rod 23. This structure can solve the problem that some sprocket adjustment frames in the prior art are adjusted in height by the screw rod 4.

When the sprocket and the chain are installed, the connecting rod 15 is unlocked by the locking block 18, and then the connecting rod 15 is moved downward, so that the gas in the air bag 19 is recovered into the air storage box 14 for use. When the support plate 12 and the connecting rod 6 are respectively in the shape of an eight and an inverted eight, the stability of the sprocket adjustment frame on the entire oil pumping unit can be improved. Secondly, when the sprocket body 1 is located in the middle position of the clamping block 24, the air bag 19 can cooperate with the sprocket body 1 to better limit and clamp the sprocket body 1.
