Embodiment Construction

[0031] refer to Figure 2 to Figure 7 As shown, a combined manhole tooling is used to install a manhole cover 1 with at least three guide sleeves 101 distributed in a ring at equal intervals on the outer peripheral surface. The axis of the guide sleeve 101 is parallel to the axis of the manhole cover 1, including the outer diameter A positioning cylinder 9 equal to the outer diameter of the manhole cover 1; at least three positioning sleeves 901 are arranged at equal intervals on the outer peripheral surface of the positioning cylinder 9, and the axis of the positioning sleeve 901 is parallel to the axis of the positioning cylinder 9;

[0032] It also includes a bracket plate 2 with a connecting rod 202 and a bracket base 201. The number of bracket bases 201 is equal to the number of positioning sleeves 901, and the bracket bases 201 are equally spaced and distributed in a virtual circle whose diameter is equal to the outer diameter of the manhole cover 1. on, so that each sup...

Abstract

The invention discloses a combined manhole tooling, which is used for installing a manhole cover with at least three guide sleeves distributed at equal intervals in a ring on the outer peripheral surface, including a positioning cylinder, a pallet frame, a positioning seat and a guide rod; the positioning seat is used for Positioned by the positioning cylinder and installed on the edge of the manhole; the guide rod is used to penetrate into the guide hole of the guide sleeve and provide support for the manhole cover, so that the manhole cover can slide along the guide rod; the two ends of the guide rod can pass through the positioning respectively The seat and the support base on the bracket plate are supported and positioned. A method for installing an internal pressure manhole, using the combined manual tooling of the present invention to install the manhole cover on the edge of the manhole. The invention gets rid of the dependence on the long lever and the driving, and a single person can complete the assembly of the combined manhole tooling and the installation of the manhole cover, with high installation efficiency and low installation cost.

Description

technical field [0001] The invention relates to the technical field of manhole installation, in particular to manhole tooling and a manhole installation method. Background technique [0002] In petrochemical industry and metallurgy, there are many high-pressure vessels, which often use internal pressure high-pressure manholes. This kind of manhole is self-tightening. The higher the pressure, the more reliable the seal. It is often used on horizontal or vertical containers, but in the manufacturing stage, manholes are generally assembled in a horizontal method. In the original manhole structure, the connecting piece is placed on the back of the manhole cover, and it is often difficult to fit under the action of its own weight. For the installation process, refer to figure 1 Shown: Switching from position 1 to vertical position 2 under external force, in position 3 requires a long lever to provide support to prevent gravity from returning to position 1, and requires a heavy o...
