Abstract
The utility model belongs to the technical filed of hydraulics, and more specifically relates to an opposite-open column. The opposite-open column comprises an upper cross beam and a slide block. A column is arranged between the upper cross beam and the slide block. A mobile shield is fixedly sleeved outside the lower portion of the column. The lower end of the mobile shield is fixed on the upper end of the slide block. A fixed shield is fixedly sleeved outside the upper portion of the column. The upper end of the fixed shield is fixed on the bottom of the upper cross beam. A gap which allows the mobile shield to pass through is arranged between the fixed shield and the upper portion of the column. The guiding surface of the column can be protected at all times, and if explosion occurs, the guiding surface of the column is not liable to any damage, thereby minimizing the frequency of maintenance. In addition, the protection device is of an opposite-open structure and is quite convenient in mounting and dismounting, such that the work intensity during maintenance is substantially reduced and the time for maintenance is shortened.
Description
Technical field
The utility model belongs to the hydraulic technique field, is specifically related to a kind of opposite opened column.
Background technology
Traditional four-column type explosive pressing hydraulic machine overwhelming majority column has no protection, and sub-fraction has relevant safeguard measure, but also can only accomplish localised protection, can not carry out the total travel protection; And the explosive pressing hydraulic machine is in the process of pressed explosive, and explosive charge is unavoidable, can directly cause the damage of guide pillar face, influences the normal use of hydraulic press.
Summary of the invention
The purpose of the utility model is: the opposite opened column that a kind of damage of can not being exploded is provided.
The purpose of the utility model is achieved in that a kind of opposite opened column, comprises entablature and slide block, between entablature and the slide block column is set, and the outside of said column bottom fixedly is nested with mobile guard shield, and said upper end of slide block is fixed in the lower end of moving guard shield; The outside on said column top is nested with secure shroud, and the entablature bottom is fixed in the upper end of secure shroud, and leaves between secure shroud and the column top to let and move the gap that guard shield passes through.
As a kind of improvement of the utility model, said mobile guard shield upper end fixedly installs gland, and the inboard of said gland fixedly installs guidance tape and dust ring.When guidance tape guarantee to move guard shield and moves up and down with slide block, have enough guiding accuracies, prevent that column from pulling; Dust ring prevents that dust from getting into, polluting column.
As a kind of improvement of the utility model, the lower inside of said secure shroud is provided with sealing ring.
The mobile guard shield of the utility model is fixed in the top of slide block, and moves up and down simultaneously with slide block; Fixed sheath is fixed in the entablature bottom; The fixed sheath bottom cooperates with mobile guard shield outer face, and the cooperation place seals through sealing ring.After mobile sheath and fixed sheath install, in fixed sheath, inject lubricant grease, the guard shield spigot surface is lubricated.
The utility model can total travel be protected the guide pillar face, and when blasting, the guide pillar face can not receive any damage, thereby has reduced maintenance frequency; In addition, because this protective device is an opposite opened, installing/dismounting is very convenient, and the working strength when greatly reducing maintenance has shortened maintenance time.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is the partial enlarged drawing of the utility model.
The specific embodiment
Like Fig. 1, shown in 2, a kind of opposite opened column comprises entablature 1 and slide block 5, between entablature 1 and the slide block 5 column 2 is set, and the outside of column 2 bottoms fixedly is nested with moves guard shield 4, and slide block 5 upper ends are fixed in the lower end of moving guard shield 4; The outside on column 2 tops is nested with secure shroud 3, and entablature bottom 1 is fixed in the upper end of secure shroud 3, and leaves between secure shroud 3 and column 2 tops to let and move the gap that guard shield 4 passes through.
Move guard shield 4 upper ends and fixedly install gland 7, the inboard of gland 7 fixedly installs guidance tape 6 and dust ring 8.
The lower inside of secure shroud 3 is provided with sealing ring 9.
Claims (3)
1. an opposite opened column comprises entablature and slide block, between entablature and the slide block column is set, and it is characterized in that: the outside of said column bottom fixedly is nested with mobile guard shield, and said upper end of slide block is fixed in the lower end of moving guard shield; The outside on said column top is nested with secure shroud, and the entablature bottom is fixed in the upper end of secure shroud, and leaves between secure shroud and the column top to let and move the gap that guard shield passes through.
2. opposite opened column according to claim 1 is characterized in that: said mobile guard shield upper end fixedly installs gland, and the inboard of said gland fixedly installs guidance tape and dust ring.
