Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Assembly method: the lock body casing 25 is fixed on the well cover 26, the shaft sleeve 3 is welded on the lock body casing 25, the main shaft 2 passes through the shaft sleeve 3, and the inside is sealed with an O-ring 4 .

[0029] Driving wheel 6 is cylindrical external gear, is enclosed within on the main shaft 2, is connected with flat key 5 in the middle, and blocks with split ring 18 outside.

[0030] The intermediate wheel 10 is also a cylindrical external gear. One side forms an external gear transmission with the driving wheel 6, and the other side forms an internal gear transmission with the driven wheel 11. The intermediate wheel 10 is in interference fit with the outer ring of the bearing 9, and the bearing 9 passes through the first screw. 8 and pressing plate 14 are fixed on the support shaft 7, and the support shaft 7 is welded on...

Abstract

The invention discloses a multi-shaft well cover lock opening device which comprises a drive wheel installed on a main shaft. A driven wheel is driven to rotate by the drive wheel through a middle wheel. The drive wheel and the driven wheel rotate in a coaxial mode but at different speeds. A large transmission rate of a gear system can be achieved through the middle wheel and a bearing, so that the rotary speed of a gear is reduced, the function of small torque inputting and large torque outputting is achieved, and the friction resistance generated by sealing of the shafts of a well cover lock is overcome. The multi-shaft well cover lock opening device solves the problem that an existing well cover lock is difficult to open. The multi-shaft well cover lock opening device is especially designed to open a lock body with a sealing requirement in a labor-saving mode, wherein the lock body with the sealing requirement is difficult to open because of the frictional resistance of a sealing ring.

Description

technical field [0001] The invention relates to a multi-axis manhole cover lock opening device, in particular to a device capable of saving effort to open a multi-axis manhole cover lock with sealing requirements. Background technique [0002] With the development of modern cities, more and more power and communication cables have adopted underground pipelines. For the convenience of maintenance and management, many manhole covers are arranged. However, manhole covers are stolen or opened illegally. Once lost or opened illegally, the phenomenon of "well eating people" or someone illegally intruding will cause damage to equipment and cables. [0003] In order to prevent the well cover from being stolen, a well cover lock is provided on the well cover. The lock body is often equipped with an electrical device for monitoring the state of the manhole cover. It is difficult for the electrical device to achieve the protection level of IP68, so the lock body is required to have t...
