Abstract
The utility model discloses a fixing device for a sand suction pump impeller casing. The fixing device comprises fixing bolts and protection bolt caps, wherein the protection bolt caps are evenly distributed in the sand suction pump impeller casing and meshed with the fixing bolts. According to the fixing device for the sand suction pump impeller casing, the protection bolt caps are arranged in the sand suction pump impeller casing and meshed with the fixing bolts, so that the fixing bolts are guaranteed against deterioration due to the calcination temperature in a calcinations process, the fixing force of the sand suction pump impeller casing is guaranteed, and the stability of the sand suction pump impeller during operation is further improved.
Description
Technical field
The utility model relates to a kind of fixing device, specifically a kind of fixing device of Sand pump impeller housing.
Background technique
Sand pump is a kind of of sand pump, is applied to large junk more and inhales sand in the river, and known Sand pump impeller housing is connected with hull by fixing bolt mostly at present.Because fixing bolt is set directly in the shell, in calcination process, because calcining heat usually can cause the material of fixing bolt to change, thereby affect the fixing of impeller housing, reduced Sand pump stability in the course of the work.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of fixing device of Sand pump impeller housing.
To achieve these goals, the technical solution adopted in the utility model is: a kind of fixing device of Sand pump impeller housing, comprise fixing bolt, and also comprise the protection nut, the protection nut is distributed in the Sand pump impeller housing, meshes with fixing bolt.
Further, the material of described protection nut is chromansil.
The utility model arranges the protection nut in the Sand pump impeller housing; and then mesh in fixing bolt; guarantee that fixing bolt can not go bad because of calcining heat in calcination process; thereby guaranteed the fixedly dynamics of Sand pump impeller housing, the stability when further having improved the work of Sand pump impeller.
Description of drawings
Fig. 1 is schematic representation of the present utility model.
Among the figure: 1, Sand pump impeller housing, 2, fixing bolt, 3, the protection nut.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1: to achieve these goals; the technical solution adopted in the utility model is: a kind of fixing device of Sand pump impeller housing, comprise fixing bolt 2, and also comprise protection nut 3; protection nut 3 is distributed in the Sand pump impeller housing 1, with fixing bolt 2 engagements.In order to guarantee to protect the worm structure of nut 3, protection nut 3 materials'use chromansils are material.
In the course of the work; the utility model arranges protection nut 3 in Sand pump impeller housing 1 calcination process; and then in fixing bolt 2 engagements; guarantee that fixing bolt 2 can not go bad because of calcining heat in calcination process; thereby guaranteed the fixedly dynamics of Sand pump impeller housing 1, the stability when further having improved 1 work of Sand pump impeller housing.
