[0018] Figure 1 It is a structural schematic diagram of the utility model.
[0019] Figure numerals: 1 safety bolt column, 2 spring, 3 slide seat, 4 base, 5 linear guide rail, 6 round nut, 7 travel switch, 8 piston cylinder. DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0021] Example 1, please refer to Figure 1 , the utility model provides a technical solution:
[0022] The pneumatic safety bolt device comprises a safety bolt column 1, a slide seat 3 and a base 4. One end of the safety bolt column 1 is connected to the inner guide of the slide seat 3, and a spring 2 is installed between the two for shock absorption.
[0023] In order to drive the device, a piston cylinder 8 is mounted on the surface of the base 4 so that the piston rod of the piston cylinder 8 is connected to the slide 3;
[0024] In order to move, a linear guide rail 5 is set on the surface of the base 4, and the linear guide rail 5 is connected to the bottom end of the slide 3 by bolts. In order to achieve in-place detection and power-off protection, a travel switch 7 is installed on the slide 3.
[0025] like Figure 1 As shown: the safety bolt column 1 is a welded component, which is provided with a processed thread and a guide cylindrical surface. The guide cylindrical surface is sleeved with the spring 2 and connected with the guide inside the slide seat 3. A fastening nut 6 for pre-tightening the spring 2 is provided on the processed thread.
[0026] like Figure 1 As shown: a positioning hole and a positioning surface are set on the base 4, so that the piston cylinder 8 passes through the positioning hole and is connected to the slide 3, a linear guide 5 is installed on the positioning surface, and a saddle is set on the linear guide 5. The saddle is connected to the bottom end of the slide 3 by bolts to realize the sliding function and ensure that the two components slide against each other.
[0027] Working principle:
[0028] The piston cylinder 8 drives the slide 3 and the safety bolt 1 assembly to move on the linear guide 5. After the safety device is in place, the travel switch 7 works and the equipment is powered off, and the operator can perform safe operations. When an abnormality occurs, the equipment slide assembly falls, and the safety bolt 1 is compressed. The spring 2 buffers and the safety bolt 1 moves down and rigidly contacts the base 4, achieving a safe support function, preventing the equipment assembly from falling further, and protecting the safety of equipment and personnel.
[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
