Description

Pressure-maintaining pressurizing hinge and welding machine thereof
Technical Field
The invention relates to a pressurizing hinge and a welding tool thereof, in particular to a pressure-maintaining pressurizing hinge and a welding machine thereof.
Background
Because the length of the construction working surface is long or short, it is difficult to ensure that the length of the water stop belt is consistent with the length of the construction working surface. When the length of the construction work surface is smaller than the length of the water stop, it is necessary to saw off the unnecessary portion of the water stop. When the length of the construction working face is greater than that of the water stop, the end parts of the two water stop are required to be lapped together for welding, and then a water stop welding machine is used.
In the prior art, the waterstop welding machine comprises a lower electric heating clamping plate and an upper electric heating clamping plate, one end of the lower electric heating clamping plate is hinged with one end of the upper electric heating clamping plate through a rigid hinge, the other end of the lower electric heating clamping plate is connected with the other end of the upper electric heating clamping plate through a rigid pressurizing locking hand wheel in a pressurizing mode, a circulating water cooling channel is arranged between the lower electric heating clamping plate and the upper electric heating clamping plate, a water inlet and a water outlet are formed in the circulating water cooling channel, and the water inlet of the circulating water cooling channel is communicated with a water source. The water source refers to a mobile cooling water tank.
The prior art water stop welding machine has the following drawbacks.
1. Because one end of the lower electric heating clamping plate is hinged with one end of the upper electric heating clamping plate through the rigid hinge, the other end of the lower electric heating clamping plate is connected with the other end of the upper electric heating clamping plate through the rigid pressurizing locking hand wheel in a pressurizing mode, when the water stop is heated and softened, the water stop is extruded to the periphery under the extrusion force action of the lower electric heating clamping plate and the upper electric heating clamping plate of the water stop welder, at the moment, the pressure of the lower electric heating clamping plate and the upper electric heating clamping plate of the water stop welder to the water stop is reduced, and in order to keep enough pressure for the water stop, the hand wheel is screwed down again in time to conduct pressure supplementary. The welding of a water stop joint needs to carry out pressure compensation many times, the operation is not complicated, moreover, the water stop welding machine with one end being a rigid hinge and the other end being a rigid pressurizing locking hand wheel can not carry out simultaneous locking of two ends, and thus, the welding fastness is reduced due to different pressures of the two ends.
2. Because lower electric heat splint and last electric heat splint are provided with the circulating water cooling passageway, and the circulating water cooling passageway is provided with water inlet and delivery port, and the water inlet and the water source intercommunication of circulating water cooling passageway, so need discharge the return water through water-cooled cooling waterstop, like this, not only pollute the environment, moreover, still need constantly pour into new water into, consume the water resource greatly. Because construction welding of tunnels and other construction sites is frequently moved and insufficient water sources are available, return water can only be recycled, and because the lower electric heating clamping plate and the upper electric heating clamping plate with high temperature heat water, the temperature of the return water is extremely high, the temperature of circulating water in a water tank is easily increased, and the continuous cooling operation effect is extremely poor. When continuous welding is needed, water is changed continuously, so that the labor intensity is high, the environment is polluted, and water resources are consumed.
