Referring to Fig. 1 to Fig. 9, the utility model proposes composite beam-balance pumping unit tail counter weight device, including a trip
1 and one tail walking beam 2 of beam, wherein, the tail end end face upper edge of the walking beam 1 is laterally spaced to be equipped with two hooks 11；
The tail walking beam 2 includes a counterweight section 21 and a linkage section formed by the head end downward bending of the counterweight section 21
22, the tail end end face of the counterweight section 21 is fixed with a backstop riser 211, and 22 upper edge of linkage section is horizontally installed with a mounting
Pipe 221, wherein, 221 hanging buckle of mounting pipe of the linkage section 22 is at two hooks 11, so that the walking beam 1 and the tail
Walking beam 2 is connected.In the utility model, by by the linkage section 22 relative to 21 bending of counterweight section and the walking beam
1 hanging buckle connects, and the tail walking beam 2 can self-tightening under the action of dead weight after suspension.Wherein, by the counterweight section 21 and connection
A bending is formed between section 22 so that the tail walking beam 2 is formed with certain angle with walking beam 1, when the head end of the walking beam 1 is pacified
When filling horse head and being at the highest notch (when i.e. described walking beam 1 swings to top dead-centre), the counterweight section 21 of the tail walking beam 2 is positioned at minimum
Position, close to ground, convenient in counterweight section 21 by adding and subtracting balance weight adjustment.It is it should be noted that for ease of description, right
In above-mentioned " transverse direction ", the width direction of the walking beam 1, tail walking beam 2 is referred to, specifically as shown in drawings.
Wherein, a connection board 31 is respectively fixed on the end face of 1 tail end of walking beam and the end face of the linkage section 22,
Two are arranged at intervals on the connection board 31 for the corresponding through-hole 32 worn of the hook, two connection boards 31 mutually paste
It closes, and passes through the connection of bolt 33 and fix.
In practical application, after the tail walking beam 2 is by mounting two hook 11 of insertion of pipe 221, in the effect of its dead weight
Under, two 31 automatic paste tightenings of connection board, the walking beam 1 and tail walking beam 2 are because the pulling force that balancing gravity generates is by mounting pipe
221 are transmitted on hook 11, and the bolt 33 does not bear the pulling force of above-mentioned balance directly, only serve it is fixed, so as to carry
The reliability of height connection.
Preferably, the mounting pipe 221 transversely wears and is fixed on the linkage section 22, close to the linkage section 22
