Embodiment Construction
[0014] The present invention will be further described below in conjunction with accompanying drawing:
[0015] Depend on Figure 1 to Figure 4 As shown, a safety anti-off straight handle wrench fixer includes a central threaded pipe, the outer wall of the central threaded pipe 1 is welded with two symmetrical connecting steel plates 2 up and down, the connecting steel plates 2 are rectangular, and are connected to the outer wall of the central threaded pipe 1 Vertically, the ends of the two connecting steel plates 2 are respectively connected with a top plate 3, and the two top plates 3 are rectangular steel plates parallel to the axis of the central threaded pipe 1. The top plate 3 and the connecting steel plate 2 are connected by top plate tie ribs 4 to play a reinforcing role.
[0016] The inside of the central threaded pipe 1 can also be connected with a screw 5, the end of the screw 5 is fixed with a baffle 6, when the crankshaft nut of the pumping unit is removed, the ...

The invention provides a safe anti-slipping straight shank spanner fixator. The problems that when an existing high-pressure 250 gate big gland and an existing pumping unit crankshaft nut are dismounted, time and labor are wasted, a spanner easily slips, and therefore the operation is not safe are mainly solved. The safe anti-slipping straight shank spanner fixator is characterized in that two connecting steel plates (2) symmetric up and down are vertically welded to the outer wall of a center threaded pipe (1), the ends of the connecting steel plates (2) are connected with a top plate (3), and the axis of the top plate (3) is parallel to the axis of the center threaded pipe (1). By means of the safe anti-slipping straight shank spanner fixator, it can be guaranteed that the spanner does not slip, and the operation is safe.
Description
technical field [0001] The invention relates to the mechanical field, in particular to a safety anti-off straight handle wrench fixer. Background technique [0002] The 250 high-pressure gate on the wellhead of the oil field is the most widely used gate with a high damage rate. In the process of gate maintenance, the large gland of the gate needs to be disassembled first, and then the internal components of the gate can be repaired. The housing of the gate is threadedly connected by two parts, the large gland and the base. Generally, the inner hexagonal glove with a special straight handle is used to place the outer hexagonal glove on the large gland, and the special wrench is used to hit the special wrench with a sledgehammer to separate the gland from the base. open. Due to the weight of the gate, the tight thread connection, the serious corrosion and rust of the thread, the outer hexagon on the extra large gland is very shallow, and the inner hexagon with a straight hand...
