Detailed Description
In order to make the technical purpose, technical solution and advantageous effects of the present invention clearer, the technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.
Example 1:
a suspension type manhole door, as shown in figures 1-3, comprises a manhole door body 3 vertically installed at an inspection manhole 2, wherein the edge position of the manhole door body 3 and the corresponding position of the inspection manhole 2 are fixedly installed through bolts 12. The manhole door body 3 is moved left and right to open and close the manhole 2. In the embodiment, a support guide rail is horizontally arranged on the outer side wall of a container 1 where an inspection manhole 2 is located, one end of the support guide rail is located above the inspection manhole 2, the other end of the support guide rail extends to one side of the inspection manhole 2, a guide body capable of moving along the support guide rail is installed in the support guide rail, the guide body is connected with a manhole door body through a rigid traction wire 6 which is vertically suspended, and the manhole door body 3 at the lower end of the rigid traction wire 6 synchronously moves while the guide body moves along the support guide rail; wherein, the lead S of the guide body that the maximum distance that the guide body moved is, the width of manhole door is W, then require S to be greater than or equal to W, can guarantee like this that inspection manhole 2 can be opened totally.
Wherein, the supporting guide rail adopts square steel 4, has seted up a bar poling 5 at square steel 4's lower terminal surface, and bar poling 5 is parallel with square steel 6 (unanimous with the direction of supporting guide rail promptly), and vertical downwardly extending in the bar poling 5 is followed to rigidity pull wire 6. The guide bodies are divided into two groups, each group of guide bodies is formed by assembling two rolling bearings 8, the two rolling bearings 8 are sleeved at two ends of the rigid shaft 7, and the assembled pair of rolling bearings 8 are arranged on the inner bottom surface of the square steel 4 and can roll along the inner bottom surface of the square steel 4; the upper end of the rigid traction wire 6 is vertically welded with the middle part of the rigid shaft 7.
In order to prevent the rolling bearing 8 from rushing out of the square steel 4, the two ends of the square steel 4 are respectively provided with a plugging piece 9 for limiting the rolling bearing 8, the plugging pieces 9 are welded at the two ends of the square steel 4, and the two ends of the square steel 4 are sealed by the plugging pieces 9.
