Abstract
The utility model discloses a weight box of a double-pulley structure, which comprises a weight box, wherein pulleys are arranged on the two sides of the weight box and are connected with guide rails on upright posts in a guide rail pair way; two pulleys are vertically arranged on both sides of the weight box and are arranged on bearing seats through bearings; the bearing seats are arranged on bearing seat brackets through fastening bolts; bolt holes on the bearing seats or the bearing seat brackets, which are matched with the fastening bolts, are slot-shaped, the bearing seat brackets are fixed on the weight box through locking bolts, and due to such structure, the weight box can be transversely adjusted along X axis; and the bolt holes on the bearing seat brackets or the weight box, which are matched with the locking bolts, are slot-shaped, and due to such structure, the weight box can be longitudinally adjusted along Y axis. Since the two pulleys are arranged on both sides of the weight box, center of gravity of the weight box is on a vertical plane of middle lines of the two guide rails all the time during vertical movement by using a two-point one-line principle, so that the swing influence during movement of the weight box and friction loss of a contact surface of pulley movement are reduced under the condition that the pulleys and the guide rails are under rational contact pressure.
Description
Technical field
The utility model relates to the ballast box of oil pumper, relates to a kind of ballast box of sister block structure specifically.
Background technology
The ballast box of oil pumper is that guideway is connected with the oil pumper upright of frame; Promptly a pulley all is set in the both sides of ballast box; The oil pumper upright of frame is provided with the oil tanker guide rail, and ballast box moves up and down in two heel posts, because the ballast box both sides all are provided with a pulley; Ballast box moves up and down, and its center of gravity is difficult to remain on the vertical plane of two guide rail center lines in the process, increases the swing influence of ballast box motion process and the frictional dissipation of pulley motion contact surface.
Summary of the invention
The purpose of the utility model just is to overcome above-mentioned deficiency a kind of sister block structure ballast box is provided.
The purpose of the utility model can realize through following measure:
A kind of sister block structure ballast box comprises ballast box, is provided with pulley in the ballast box both sides, and pulley is that guideway is connected with the column upper rail, and said ballast box both sides all vertically are provided with two pulleys.
A kind of sister block structure ballast box; Pulley is arranged on the bearing support through bearing; Bearing support is installed on the bearing bracket through fastening bolt; The bolt hole that matches with fastening bolt on bearing support or the bearing bracket is a long groove shape, and bearing bracket is fixed on the ballast box through lock bolt, and such structure can laterally be adjusted ballast box at the X axle.
Above-mentioned sister block structure ballast box, the bolt hole that matches with lock bolt on said bearing bracket or the ballast box is a long groove shape, this structure can vertically be adjusted ballast box at the Y axle.
Adopt technique scheme; The utility model has following advantage: owing to be provided with two pulleys in the both sides of ballast box; Utilize the principle of two one lines make ballast box in the process of moving up and down its center of gravity all the time on the vertical plane of two guide rail center lines; Connect through the bolt between pulley spindle bearing, bearing bracket and the ballast box; Can laterally vertically finely tune at the X axle with the Y axle, thus the assurance ballast box in the process of moving up and down its center of gravity all the time on the vertical plane of two guide rail center lines, through selecting for use of rational mechanism design and wheel body material; Make pulley and guide rail under the condition of rational contact pressure, reduce the swing influence of ballast box motion process and the frictional dissipation of pulley motion contact surface.
