Description

Detachable clamp for balance fixing device

Technical Field

The application relates to the technical field of fasteners, in particular to a detachable clamp for a balance fixing device.

Background

The inclined shaft is an engineering structure type widely applied to a water conduit system of a hydroelectric power station. Almost all large mixed-flow hydroelectric generating sets or pumped storage power stations are provided with water-conducting steel pipe inclined shafts with large diameters and large inclination angles. The safety state of the inclined shaft is closely related to the operation reliability of the whole hydroelectric power station. When the steel pipe inclined shaft is overhauled, the movable trolley is required to be used, the movable trolley is required to pull the movable trolley to move when the movable trolley is checked and maintained in the steel pipe inclined shaft, and the winch is installed on the base and can be used for construction operation in the steel pipe inclined shaft.

In order to ensure the operation safety of a dam and a power station, deep hole drilling and foundation bolts are forbidden to be buried in a steel pipe inclined shaft and a water inlet of the steel pipe inclined shaft, and mechanical parts are also forbidden to be welded on the inner wall of the steel pipe. If the base of the winch is welded in the steel pipe inclined well, the strength of the welding point between the inner wall of the steel pipe and the base is not enough to bear the traction force of the movable trolley, so that danger is easy to occur.

However, the winch of the traction mobile type trolley can be fixed on the fixed cross beam of the gate slot through the balance fixing device, the balance fixing device comprises a supporting seat fixedly connected with the fixed cross beam, a rope wheel arranged on the supporting seat and a connecting rope used for connecting the base and the fixed cross beam, one end of the connecting rope is arranged on the base, and the other end of the connecting rope is connected on the base by bypassing the rope wheel.

Each supporting seat needs to be fixed on the fixed cross beam, and the connecting rope is connected to the base after bypassing the rope wheel, so that when the base is inclined, the base is conveniently moved to be aligned, and the traction movable trolley can be ensured to stably move under the traction action of the traction rope; the fixed beam is fixed in the gate slot, and the base is connected the rope and is held, receives external force at the base and draws when dragging, can guarantee that the hoist engine on the base is by stable fixed.

Generally, the supporting seat is directly connected with the fixed cross beam through bolts, bolt holes must be formed in the fixed cross beam in advance by using the method, however, the gate slot is an inherent structure of the steel pipe inclined shaft, the fixed cross beam is clamped in the gate slot to fix the base, and in order to protect the steel pipe inclined shaft, other fixing modes which damage the steel pipe inclined shaft are preferably not carried out in the steel pipe inclined shaft.

The maintenance and repair of inclined shaft are a repetitive work, if work at every turn all punches on fixed cross beam, can increase work load, and the staff still needs to carry more punching appliances more, and is inconvenient, and the gate slot is concrete steel structure, and intensity is big, is difficult for punching, even beat the bearing capacity that the hole also probably destroyed the dam when wasting time and energy.

Therefore, a new solution is needed to solve the above problems.

SUMMERY OF THE UTILITY MODEL

To overcome the defects in the prior art, the detachable clamp for the balance fixing device is provided.

The above object of the present application is achieved by the following technical solutions:
