Abstract
The utility model discloses a stagnation-proof mechanism for a concrete pumping oil cylinder, comprising a guide sleeve and a pressure cover of the oil cylinder, wherein the pressure cover is connected with a connection screw hole of the guide sleeve by a bolt; one screw hole of the guide sleeve, corresponding to the pressure cover, deflects by a certain angle relative to the original position; an O-shaped sealing ring is arranged on a drain hole so as to play a sealing role; and the drain hole is drilled at the bottom of the original position of the deflected screw hole. The stagnation-proof mechanism avoids the mistaken assembling at the connection part of the pressure cover and the drain hole of the guide sleeve, avoids the loss caused by reworking, and is convenient to assemble.
Description
Technical field
The utility model relates to the constructional engineering machinery technical field, is specifically related to a kind of concrete pumping oil cylinder fool proof mechanism.
Background technique
Available coagulation soil pumping oil cylinder does not have fool proof mechanism, in the assembly process of oil cylinder, because gland screw and guide sleeve screw are uniform, if not careful conscientious, it is wrong to be easy to a gland and guide sleeve water-leaking hole joint dress, makes the O RunddichtringO inoperative, and be not easy to find, cause product defect, the oil cylinder that assembles is done over again because of this problem, prolonged the manufacture cycle.
Summary of the invention
Technical problem to be solved in the utility model is: solve the problem that above-mentioned prior art exists, and a kind of gland and joint loading error of guide sleeve water-leaking hole and concrete pumping oil cylinder fool proof mechanism easy to assembly of avoiding is provided.
The technical solution adopted in the utility model is: this concrete pumping oil cylinder fool proof mechanism, the guide sleeve and the gland that comprise oil cylinder, gland connects with bolt with the screw that is connected of guide sleeve, but in the screw of gland and guide sleeve, one of them screw has been offset several angle equally on original position.Like this, just a kind of assembly method can only be arranged when assembling, the O RunddichtringO all on water-leaking hole, has played seal action.
In the technique scheme, the former screw bottom of skew is used for boring water-leaking hole.
This concrete pumping oil cylinder fool proof mechanism that the utility model provides adopts a kind of simple and practical method, changes screw and distributes, and just can not make a fault when assembling, has avoided oil cylinder gland and the joint loading error of guide sleeve bolt hole, prevents to do over again.The utility model is not only simple in structure, and its assembling is also very convenient, has saved the manufacturing time greatly.
Description of drawings:
Fig. 1 is the utility model assembling schematic representation;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the guide sleeve structural representation;
Fig. 4 is the left view of Fig. 3;
Fig. 5 is an oil cylinder gland structure schematic representation;
Fig. 6 is the left view of Fig. 5.
Embodiment:
Referring to accompanying drawing, from Fig. 1～Fig. 6 as can be seen, this concrete pumping oil cylinder fool proof mechanism that the utility model provides, the guide sleeve 1 and gland 2 that comprise oil cylinder, gland 2 connects with the screw 3 usefulness bolts that are connected of guide sleeve 1, but one of them screw 4 has been offset 15 ° on original position, has just had only a kind of assembly method when assembling.
Oil cylinder guide sleeve and its screw of gland of traditional no fool proof mechanism are evenly distributed, when assembling as long as the hole aimed at just can adorn, if still not careful, water-leaking hole not to be aimed at, O type circle can't play seal action, and water can't be discharged from water-leaking hole, the oil cylinder refitting of just must doing over again.
Claims (2)
1. concrete pumping oil cylinder fool proof mechanism, it is characterized in that: the guide sleeve and the gland that comprise oil cylinder, gland connects with bolt with the screw that is connected of guide sleeve, but wherein corresponding screw skew equally on original position in the screw of gland and guide sleeve, the O RunddichtringO is all on water-leaking hole.
2. concrete pumping oil cylinder fool proof according to claim 1 mechanism is characterized in that: the former screw bottom of skew is used for boring water-leaking hole.
