Description

Technical Field

[0001] The utility model relates to the technical field of vertical oil pumping units, in particular to a device for fixing and installing a counterweight block of a vertical oil pumping unit. Background Art

[0002] Vertical pumping units often use a balance box to directly balance the wellhead load, which has the characteristics of good balancing effect and convenient space setting. At present, a number of counterweights are placed in the common balance box. The balance adjustment during the installation and use process is completed by manually taking and placing the counterweights. For this reason, the weight of the counterweights is mostly set at around 5-20kg. At the pumping unit use site, the weight adjustment range of the balance box of the pumping unit is determined according to the wellhead load, and the adjustment range is usually between 2-8 tons.

[0003] In the prior art, the publication (announcement) number is: CN201865635U, a vertical oil pumping unit counterweight box, which is composed of a counterweight box body and a counterweight block installed in the counterweight box body. The counterweight box body is divided into an upper box body and a lower box body. The counterweight blocks installed in the box body are divided into fixed counterweights and adjustable counterweights. The fixed counterweights are directly cast in the box body or a large counterweight block with a large weight and difficult to move is used. The adjustable counterweight is smaller in weight and volume, and will be manually adjusted according to the working conditions of the oil well. The upper box body is the main counterweight, and the lower box body is the auxiliary counterweight. There is a link structure between the upper and lower boxes that can be separated and connected. A guide pulley that constrains the up and down movement of the counterweight box can also be added to the upper counterweight box.

During the installation process, the positioning and installation effect of the counterweight block is not good, which is easy to generate noise and safety hazards. Therefore, it is necessary to provide a vertical oil pump counterweight fixing installation device. Utility Model Content
