A special up and down well device for inspection wells

Abstract

The invention discloses a well clamping up and down device special for an inspection well, and belongs to the technical field of drainage facilities. The well clamping up and down device comprises a clamping ring. A horizontal U-shaped seat is fixed to one side of the top of the clamping ring. An inner cavity of the U-shaped seat is rotatably provided with a cross beam through a rotating shaft. Auniversal wheel is fixed to the bottom of the cross beam through a sliding block and a sliding groove, and the universal wheel is connected with the top of the clamping ring in a clamping mode. The outer wall of the cross beam is connected with a steel wire rope through a lifting hook. The bottom end of the steel wire rope is fixedly winded with a winding reel. The steel wire rope is winded on thewinding reel to raise a combined accommodating box. When the combined accommodating box rises near a well head, feet and a foot pedal make a pawl and a ratchet wheel overlapped with each other to clamp an output shaft of a gear type reduction box, so that the winding reel do not rotate; and when the combined accommodating box moves near the well wall, workers climb out with hands holding the wellhead. The well clamping up and down device is convenient to combine and install and easy to carry, workers can complete clamping up and down wells alone, the well clamping up and down device can be reused, and the folding combined accommodating box is suitable for inspection wells with different calibers.

Description

technical field [0001] The invention relates to the technical field of drainage facilities, in particular to a special upper and lower well device for inspection wells. Background technique [0002] In occasions such as urban water supply and drainage, as well as occasions such as underground laying of cables, there are more and more buried wells such as plastic inspection wells, installation wells, and even water meter wells and electric meter wells, which have become common facilities. Especially in the urban rainwater and sewage discharge pipe network system, inspection wells are often used for dredging and maintenance of the rainwater and sewage discharge pipe network. And these inspection wells generally have certain degree of depth, need just could go down in the well with ladder. Existing ladder mainly contains single ladder, herringbone ladder. The two ends of the single ladder need to rely on the wall and the bottom surface to keep it stable for people to go up an...
