Problems solved by technology

[0003] Existing pumping units are generally used to achieve reciprocating motion by rotating speed and adding a balance iron counterweight. The disadvantages of this type of pumping unit are high energy consumption, not environmentally friendly, and a high-power power distribution system is required. High voltage power supply and transformer must be available for power supply support
This type of model is inconvenient to install, and requires heavy trucks to transport and configure cranes, and requires advance preparation and construction of civil works
This type of machine is installed on a high prefabricated platform, and the equipment feet are fixed with long rod bolts. When the downhole conditions change suddenly and the sucker rod breaks, the pumping unit will fall over and be damaged, causing serious production accidents.
Operators need the cooperation of multiple people at the same time to operate when starting and stopping. If the cooperation is not good, serious accidents may occur

Embodiment approach

[0161] Method 1: at least four buffers 1210 are provided, and the distribution of the buffers 1210 can be arranged according to the shape of the bottom surface of the counterweight box 300 , for example, if the bottom surface of the counterweight box 300 is quadrilateral, the buffers 1210 can be arranged correspondingly. The buffer pad 1220 is laid around the periphery of the buffer 1210 . When the counterweight box 300 moves to the bottom of the frame 100 , the buffer 1210 touches the bottom of the counterweight box 300 and is close to the edge of the counterweight box 300 , and the buffer pad 1220 is attached to the bottom of the counterweight box 300 .

[0162] Manner 2: A buffer 1210 is provided. The buffer 1210 is disposed according to the center of gravity of the weight box 300 . The buffer pad 1220 is laid around the buffer 1210 . When the counterweight box 300 moves to the bottom of the rack 100 , the buffer 1210 touches the bottom of the counterweight box 300 and is...

example 1

[0164] Example 1: The crane 200 is provided with a first pulley 220 , at least one second pulley 230 and at least two third pulleys 240 . The side of fixed seat 403 is provided with a wedge joint 408, and fixed pulley block 405 comprises at least two fixed pulleys, and movable pulley block 406 comprises at least two movable pulleys, and fixed pulley block 405 has a plurality of fixed pulleys, and movable pulley block 406 has a plurality of movable pulleys.

[0165]In this case, one end of the first pulling rope 510 is connected to the wedge joint 408 for fixing. The rope body of the first traction rope 510 is wound on the upper part of the movable pulley and the lower part of the fixed pulley in turn from close to the wedge joint 408 to away from the wedge joint 408 (that is, the first traction rope 510 is wound around the outside of the movable pulley and the fixed pulley); the remaining rope bodies Wind around the top of the first pulley 220 and one of the third pulleys 240 ...

example 2

[0167] Example 2: The crane 200 is provided with two first pulleys 220 , at least one second pulley 230 and at least three third pulleys 240 . Both sides of fixed seat 403 are provided with wedge joint 408 respectively, and fixed pulley block 405 comprises at least two fixed pulleys, and movable pulley block 406 comprises at least two movable pulleys, and fixed pulley block 405 has a plurality of fixed pulleys, and movable pulley block 406 has a plurality of movable pulleys.

[0168] In this case, the remaining rope bodies on both sides of the first traction rope 510 are respectively wound around the upper part of the movable pulley and the lower part of the fixed pulley from the middle of the booster assembly 400 to the wedge joint 408 (that is, the first traction rope 510 is wound around the movable pulley and the fixed pulley). pulley), and the first traction rope 510 is connected to the wedge joint 408, while the first traction rope 510 is connected to the first rope hanger...

Abstract

The invention discloses a hydraulic pumping unit without a walking beam, and relates to the technical field of chemical devices. The hydraulic pumping unit without the walking beam is characterized inthat the top of a rack is connected with a crown block; a first traction rope penetrates through the crown block, and the first traction rope is connected with a power assisting assembly and an oil well polish rod; the power assisting assembly is transversely arranged and is adjacent to the rack, and the power assisting assembly is used for pulling the oil well polish rod; a second traction ropepenetrates through the crown block, and the second traction rope is connected with a weight box and the oil well polish rod; and the weight box can move in the vertical direction along the rack. According to the embodiment, the energy consumption can be reduced, and the mechanical efficiency can be improved; the load, the stroke and the stroke frequency of the hydraulic pumping unit without the walking beam can be conveniently adjusted, and the stroke is maximized; the installation and maintenance are easy; the application range is wide; and the safety is good.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a beamless hydraulic pumping unit. Background technique [0002] The pumping unit is a kind of machinery and equipment for oil extraction, and the pumping unit is the most important lifting device in the rod pumping system. According to whether there is a beam, it can be divided into a beam pumping unit and a beam pumping unit without a beam. [0003] Existing pumping units are generally used to achieve reciprocating motion by rotating speed and adding a balance iron counterweight. The disadvantages of this type of pumping unit are high energy consumption, not environmentally friendly, and a high-power power distribution system is required. Must have high voltage power supply and transformer to realize power supply support. This type of model is inconvenient to install, and requires heavy trucks to transport and configure cranes, and requires advance preparation and ...
