Abstract
The utility model relates to a counter weight pulley mechanism of a main shaft box of a floor-typed boring machine, which ensures a polish rod to keep balance and to run for normal working when a lathe is run by a lathe polish rod. The mechanism comprises a main shaft box (1), chain wheels (2), a chain (3), a counter weight (4) and a chain guide device, wherein the two chain wheels (2) are distributed left and right in parallel; the middle part of the chain (3) moves around the two chain wheels (2); the two ends of the chain (3) are respectively connected with the main shaft box (1) and the counter weight (4); and the chain guide device is arranged at the top part of the floor-typed boring machine and is matched with the chain (3). The counter weight pulley mechanism of the main shaft boxof the floor-typed boring machine can not cause the problem that the chain is fractured due to the adoption of the chain wheel mechanism and the chain mechanism, and the safety and the reliability arehigh.
Description
(1) technical field
The utility model relates to a kind of normal device that uses of lathe that keeps, and particularly a kind of lathe polished rod keeps the floor type boring machine main spindle box counterweight pulley mechanism of balance and operate as normal running to polished rod when the running lathe.
(2) background technology
The main spindle box of former boring machine can play the balance safety effect during for lifting in use, make the lathe motion that remains a constant speed in the process of walking, therefore having installed the counterweight pulley mechanism additional, all is that what to adopt is steel wire rope and pulley structure transition between original design main spindle box and the counterweight.In actual use, there is serious unsafe factor in the frequent breakage problem of counterweight cable wire.Reason one is that to land boring main spindle box counterweight diameter of pulley too little, the 2nd, and steel wire rope is too thick, must use so thick steel wire rope but will bear certain load, because often distortion by bending, the little lateral curvature of inboard curvature of cable wire is big, therefore causes fracture of wire.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of security reliability high floor type boring machine main spindle box counterweight pulley mechanism.
The purpose of this utility model is achieved in that a kind of floor type boring machine main spindle box counterweight pulley mechanism, comprise main spindle box, sprocket wheel, chain, counterweight and chain guide, described sprocket wheel has two, about be arranged in parallel, walk around described two sprocket wheels in the middle of the described chain, the chain two ends are connected with counterweight with main spindle box respectively, and described chain guide is arranged on the top of floor type boring machine, match with described chain.
The beneficial effects of the utility model are:
Adopt the sprocket wheel link chain mechanism the chain breakage problem can not occur, increased by a cover chain guide simultaneously at the top of lathe, chain shaft can not occur, also can not cause the chain breakage problem to off-set phenomenon.So security reliability height.

Fig. 1 is the structural representation of the utility model floor type boring machine main spindle box counterweight pulley mechanism.
Among the figure:
Sprocket wheel 2
(5) specific embodiment
Referring to Fig. 1, the utility model floor type boring machine main spindle box counterweight pulley mechanism comprises main spindle box 1, sprocket wheel 2, chain 3, counterweight 4 and chain guide composition.Described sprocket wheel 2 has two, about be arranged in parallel, walk around described two sprocket wheels 2 in the middle of the described chain 3, two ends are connected with counterweight 4 with main spindle box 1 respectively, described chain guide is arranged on the top of described floor type boring machine, guiding matches with described chain 3.
Claims (1)
1, a kind of floor type boring machine main spindle box counterweight pulley mechanism, it is characterized in that described mechanism comprises main spindle box (1), sprocket wheel (2), chain (3), counterweight (4) and chain guide, described sprocket wheel (2) has two, about be arranged in parallel, walk around described two sprocket wheels (2) in the middle of the described chain (3), chain (3) two ends are connected with counterweight (4) with main spindle box (1) respectively, and described chain guide is arranged on the top of floor type boring machine, match with described chain (3).
