Abstract
The invention relates to a trigger type connecting device for a weight box of a vertical oil pump unit. The trigger type connecting device comprises a hook body, wherein the middle of the hook body is rotationally connected with the weight box; a hook is arranged at the bottom of the hook body, and a hook pulling plate is arranged on the top of the hook body; a hooking hole is formed in the hook pulling plate. The connecting device further comprises a telescopic spring, one end of the telescopic spring is fixed in the hooking hole, and the other end of the telescopic spring is connected with a fixed plate on the weight box. The trigger type connecting device is simple in structure, automatic loading and unloading are realized by changing a hooking position according to a spring reset principle, safety and reliability are realized, and repeated operating time is shortened. The working efficiency is increased, the safety risk and current impact of frequent operation on a permanent magnet motor are lowered, and loading and unloading can be finished at one time.
Description
Technical field:
The present invention relates to petroleum collection field of mechanical technique, be specifically related to counterweight box of vertical oil pumping unit trigger type connection set.
Background technique:
The current hook mode of vertical straight drive pumping unit balancing weight: adopted original hook form, when carry or unloading, need the gap between upper and lower ballast box to eliminate ability carry or unloading completely, but can not make the gravity of ballast box discharge completely, operation easier is very large, often causes ballast box in balance and bounce-back up and down repeatedly between laying particular stress on.Cannot in ballast box is laid particular stress on the bounce-back time, complete carry or unloading, during to operation, band-type brake cooperation is had relatively high expectations, and is difficult to once complete carry and unloading.
Summary of the invention:
The object of this invention is to provide counterweight box of vertical oil pumping unit trigger type connection set, it is simple in structure, utilize spring reset principle, by change, be affiliated to position and realize automatic carry and unloading, not needing to increase cost drops into, at original hook mounting point Installation of New Type hook, safe and reliable, shortened the repeatable operation time.Increase work efficiency, reduce security risk and the rush of current of frequent operation to magneto, carry and unloading all can once complete.
In order to solve the existing problem of background technique, the present invention is by the following technical solutions: counterweight box of vertical oil pumping unit trigger type connection set, comprise hanger bulk, middle part and the ballast box of described hanger bulk are rotationally connected, and described hanger bulk bottom is hook, and top is provided with a hook arm-tie, described hook arm-tie is provided with hanging hole, on described connection set, also comprise a coil tension spring, described coil tension spring one end is fixed in hanging hole, and the other end is connected with the fixed plate on ballast box.
Further concrete, in described hanging hole, be provided with a hook pull bar, fixing coil tension spring on described hook pull bar one end, the other end of described hook pull bar is fixed in hanger bulk.
The present invention has following beneficial effect: it is simple in structure, utilize spring reset principle, by change, be affiliated to position and realize automatic carry and unloading, do not need to increase cost and drop into, at original hook mounting point Installation of New Type hook, safe and reliable, shortened the repeatable operation time.Increase work efficiency, reduce security risk and the rush of current of frequent operation to magneto, carry and unloading all can once complete.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the right elevation of Fig. 1;
Fig. 3 is carry status architecture schematic diagram of the present invention;
Fig. 4 is unloaded state structural representation of the present invention.
Embodiment:
Referring to Fig. 1-2, this embodiment is by the following technical solutions: counterweight box of vertical oil pumping unit trigger type connection set, comprise hanger bulk 1, middle part and the ballast box of described hanger bulk 1 are rotationally connected 6, and described hanger bulk 1 bottom is hook, and top is provided with a hook arm-tie 2, described hook arm-tie 2 is provided with hanging hole 7, on described connection set, also comprise a coil tension spring 4, described coil tension spring 4 one end are fixed in hanging hole 7, and the other end is connected with the fixed plate 5 on ballast box; In described hanging hole 7, be provided with a hook pull bar 3, fixing coil tension spring 4 on described hook pull bar 3 one end, the other end of described hook pull bar 3 is fixed in hanger bulk 1.
This embodiment working principle: during carry, upper ballast box declines, 4 one of coil tension springs are suspended to hook pull bar 3 upper ends (as Fig. 3), coil tension spring 4 is in extended state, and when the inclined-plane of hanger bulk 1 touches the nowel hanging column on ground, hanger bulk 1 is rotation offset left, drive immediately coil tension spring 4 to stretch, when hanging column surpasses hanger bulk 1 mouth, hanger bulk 1 is subject to coil tension spring 4 reset response power to catch on rapidly hanging column, completes carry.
During unloading, ballast box declines, and 4 one of coil tension springs are suspended to hook pull bar 3 bottoms (as Fig. 4), and coil tension spring 4, in extended state, when ballast box bottom touches ground, loses gravity between hanger bulk 1 and nowel hanging column.Hanger bulk 1 turns left under coil tension spring 4 reset response power, reaches the object of rapid unhooking.
This embodiment has following beneficial effect: it is simple in structure, utilize coil tension spring reset principle, by change, be affiliated to position and realize automatic carry and unloading, not needing to increase cost drops into, at original hook mounting point Installation of New Type hook, safe and reliable, shortened the repeatable operation time.Increase work efficiency, reduce security risk and the rush of current of frequent operation to magneto, carry and unloading all can once complete.
