Abstract
The utility model provides a hydraulic support guide rod mechanism with a safety device, which comprises a guide sleeve, wherein a guide rod is arranged in the guide sleeve in a sliding way, one end of the guide rod is connected with a spring, and the other end of the guide rod is connected with a side guard plate; the guide rod is provided with a limiting groove along the length direction of the guide rod, the guide sleeve is provided with a threaded hole corresponding to the limiting groove, a limiting bolt is arranged in the threaded hole, and the screw part of the limiting bolt is in sliding fit with the limiting groove. The device is through seting up the spacing groove on the guide arm to utilize spacing bolt and spacing groove's cooperation, guaranteed the security of support in maintenance or the disassembly process, prevent that the guide arm from popping out and hindering the people, improved operation security.
Description
Technical Field
The utility model relates to a hydraulic support field, specific theory has related to a take safety device's hydraulic support guide arm mechanism.
Background
The hydraulic support side guard device generally uses a spring and a guide rod to ensure the smooth ejection of the side guard plate, and the guide rod not only plays a role in guiding, but also has larger stress in the using process. Bending deformation and the like can occur on part of the guide rod. In the maintenance process, the guide rod needs to be disassembled, jamming can occur on the bent guide rod, and the accident that the guide rod flies out to hurt people can occur when the spring is in a compressed state in the disassembling process.
In order to solve the above problems, people are always seeking an ideal technical solution.
SUMMERY OF THE UTILITY MODEL
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: a guide rod mechanism of a hydraulic support with a safety device comprises a guide sleeve, wherein a guide rod is arranged in the guide sleeve in a sliding mode, one end of the guide rod is connected with a spring, and the other end of the guide rod is connected with a side protection plate;
the guide rod is provided with a limiting groove along the length direction of the guide rod, the guide sleeve is provided with a threaded hole corresponding to the limiting groove, a limiting bolt is arranged in the threaded hole, and the screw part of the limiting bolt is in sliding fit with the limiting groove.
Based on the above, the length value of the limiting groove is smaller than that of the guide rod.
Based on the above, the limiting bolt is perpendicular to the axis of the guide rod.
Based on the above, the spring is a compression spring.
Based on the above, the side guard plate is perpendicular to the axis of the guide rod.
The utility model discloses relative prior art has substantive characteristics and progress, specific theory, the utility model provides a take safety device's hydraulic support guide arm mechanism is through offering the spacing groove on the guide arm to utilize the cooperation of spacing bolt and spacing groove, guaranteed the security of support in the maintenance or disassemble the in-process, prevent that the guide arm from popping out and hindering the people, improved the operational safety nature.
Drawings
Fig. 1 is a schematic view of an assembly structure of a hydraulic bracket guide rod mechanism with a safety device provided by the present invention.
Fig. 2 is a schematic view of a partial structure of a hydraulic bracket guide bar mechanism with a safety device according to the present invention.
In the figure: 1. a side guard plate; 2. a guide bar; 3. a spring; 4. a guide sleeve; 5. a limit bolt; 6. a limiting groove.
Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
Example 1
The embodiment provides a hydraulic support guide rod mechanism with a safety device, as shown in fig. 1 and 2, the hydraulic support guide rod mechanism comprises a guide sleeve 4, and a guide rod 2 is slidably arranged in the guide sleeve 4. One end of the guide rod 2 is connected with a spring 3, and the other end of the guide rod 2 is connected with a side guard plate 1.
And a limiting groove 6 is formed in the guide rod 2 along the length direction of the guide rod. The guide sleeve 4 is provided with a threaded hole corresponding to the position of the limit groove 6, and a limit bolt 5 is arranged in the threaded hole. And the screw part of the limiting bolt 5 is in sliding fit with the limiting groove 6.
Wherein, the length value of the limiting groove 6 is smaller than that of the guide rod 2. The limiting bolt 5 is perpendicular to the axis of the guide rod 2. The spring 3 is a pressure spring. The side guard plate 1 is perpendicular to the axis of the guide rod 2.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
