Description

Two-way pumping machine for injecting two-component chemicals {PUMPING DEVICE FOR TWO COMPONENT REPAIR-LIQUID GROUTING}

The present invention relates to a two-way pump for mixing and injecting two-component chemicals into the cracks of concrete structures, and more particularly, the main liquid and the curing agent are discharged sequentially by having a proper ratio of the chemicals in the stored chemical containers. The present invention relates to a two-component pump for injecting two-component chemical liquids, which allows the curing agent to achieve a stable mixing and at the same time obtain a large force with low power.

In general, the construction and piers are made of concrete or stone structures, such cracks are generated after a long time after construction, and when the foreign matter such as rainwater penetrates the gap, the rainwater is capillary inside the structure As it penetrates into the furnace, the volume expansion due to temperature change or pressure difference further expands the gap or corrodes the internal basic structure, causing severe collapse of the structure.

Accordingly, a repair liquid is injected to repair the crack gap, and the repair liquid is injected by using a syringe-shaped injector or a repair liquid injection device according to the gap of the crack gap.

In other words, the repair liquid injector forcibly injects epoxy mixed with the main material and hardener into the cracks in the wall of the building or the bridge structure to prevent cracking and waterproofing by cracking or cracking the cracks during solidification of the epoxy. To make it possible.

The repair liquid injector has been filed by the applicant of the present application and registered as a utility model No. 121552, which is fixed to one side of the piston and the outer peripheral surface of the cylinder, the liquid is introduced into the cylinder by the vacuum pressure during the piston movement A chemical liquid container to be injected, a nozzle-shaped nipple provided at the front end of the cylinder to prevent backflow of liquid by a check valve and connected to a hose, and a slider provided at the rear end of the cylinder to reciprocate the piston And a drive unit for moving the slider back and forth by a plurality of rotary gears in accordance with the rotation of the motor provided above the slider.

The epoxy injection device having the above-described configuration linearly reciprocates the slider by an eccentric rotary cam provided in the rotary gear by rotating a large or small diameter rotary gear connected thereto while the motor shaft is rotated when power is applied to the motor during operation. As a result, the piston connected to the slider is reciprocated back and forth to push out the liquid flowing from the chemical container, and the moving liquid is injected into the crack gap through the hose while pushing the ball of the check valve by the hydraulic force. When the power is turned off afterwards, the ball of the check valve closes the inlet end of the nipple by the spring force.

The pumping device for the epoxy injection is a mixture of the main body and the curing agent in the chemical liquid container provided on the cylinder and then used as the injection time is delayed or when the liquid is left in the remaining state, the epoxy moves the nozzle, etc. in the device. Problems that can harden in the device to induce a defect of the device itself, or a problem that the remaining maintenance liquid is not reused.

In order to solve this problem, the applicant has to keep the chemical liquid container as the main agent and the curing agent, and to allow the chemical liquids from the separated chemical liquid container to be moved by the pumping machine and discharged simultaneously with mixing in the mixing chamber. It has been filed. That is, the main body and the curing agent are separately stored in the chemical container, and during the pumping operation, the main body and the curing agent are injected into the injection gun through the two hose lines at the proper ratio, and then mixed and injected into the crack gap at the same time. Through the pivoting bar which is moved by the iso-scissor as the main cylinder, it is possible to simultaneously operate the first and second pumps that pump the main and the hardeners respectively, and to adjust the piston stroke distance of one of them. The mixing ratio can be easily adjusted, and the main body and the curing agent are mixed at the same time as the injection into the crack gap through the injection gun to prevent the mixed repair liquid from hardening in the equipment. Water can be added to the water so that the mixed It is to be prevented. In addition, the rotating bar having the lever principle allows the pump to generate a large pump pressure even with a small cylinder stroke, while the rotation bar is provided with a pinhole for adjusting the stroke distance of the cylinder to adjust the discharge amount of the pump.

However, the pumping device has a large structure, and thus there is a problem in that the pumping device does not quickly cope with the actual work site.

In addition, the main body and the curing agent are sprayed after being mixed while being discharged in the mixing chamber at the same time, there is a problem that the main agent and the curing agent are sprayed even before the stable mixing is made.

The present invention has been devised to solve the above problems, and the object of the present invention is to allow a more stable mixing effect by allowing the main and the curing agent to be mixed while sequentially discharging the main and the curing agent. .

Another object of the present invention is to enable a motor shaft of a rotating electric drive to reciprocate a piston member for pushing chemicals directly so that a large force can be obtained with less power.
