Abstract
The utility model discloses a pumping unit braking jackscrew free of being locked by a tool. The problem that personal injuries and equipment trouble can happen easily due to the defects of a traditional jackscrew is solved. The pumping unit braking jackscrew free of being locked by the tool is composed of a handle and a lead screw, wherein the handle is vertically connected with the lead screw, and a screw thread is arranged in the middle part of the lead screw. According to the pumping unit braking jackscrew free of being locked by the tool, the handle is arranged on the jackscrew self, an operator does not need to use the tool, a pumping unit brake fuse can be locked through manual operation, and therefore operating risks caused by damage of the jackscrew can be avoided.
Description
Technical field
The utility model relates to a kind of pumping unit brake jackscrew of exempting from instrument locking, belongs to the oil development technical field.
Background technique
When pumping unit is worked, pumping unit brake jackscrew is the vitals of guaranteeing equipment and operator's person safety, this M12 * non-cap jackscrew of 1.75 straight groovees cooperates to come locked brake lever with the movable lock dog of braking device, with personal injury and the device damage that prevents from causing because of brake misoperation.Yet in actual production, also there is following problem in this jackscrew:
A, tool using could be operated; The straight groove of the non-cap jackscrew afterbody of straight groove can only be operated with straight screwdriver.
B, the Dimensions of straight screwdriver there is certain requirement.
C, straight groove mouth damage easily; Because operation is frequent, the straight groove of jackscrew weares and teares expansion easily and can't use and repair.
D, damage box screw thread; In tool using when operation,, the box of damaging easily makes the jackscrew can't normal running.
E, the burden that has increased the operative employee and operational risk; Must carry the straight screwdriver of corresponding specification and just can operate, otherwise, can increase operational risk because can't lock pumping unit brake insurance.
Summary of the invention
The purpose of this utility model is to provide a kind of pumping unit brake jackscrew of exempting from instrument locking, and it can avoid reducing operating risk because having personal injury and the device damage that the jackscrew defective causes now.
Concrete technological scheme of the present utility model is as follows:
Originally exempt from the pumping unit brake jackscrew of instrument locking and be made up of handle and screw mandrel, handle vertically connects screw mandrel, and screw thread is located at the screw mandrel middle part.
The utility model jackscrew carries handle, makes the operator needn't tool using, relies on manually-operable can lock pumping unit brake insurance, thereby avoids the personal injury and the device damage that produce because of traditional jackscrew defective, reduces operating risk.
Description of drawings
Fig. 1 is the pumping unit brake jackscrew schematic representation of exempting from instrument locking.
