Description

Pumping apparatus for injecting liquid material

The present invention relates to a pumping device for injecting chemical liquids, and more particularly, it is easy to assemble and disassemble by improving the overall structure of the device, and to facilitate the cleaning and maintenance work, thereby reducing the damage of the device and including epoxy. The present invention relates to a pumping device for injecting a chemical solution for allowing selective adjustment of the repairing chemical liquid in both directions or pumping in one direction.

Cracks are likely to occur on walls and ceilings of buildings. In particular, the older the building, the larger the amount of cracks and crevices. Even if there is a crack in the wall or ceiling, the building may collapse if it is not properly maintained.

Therefore, as a method for maintaining cracks generated in walls or ceilings, chemicals such as epoxy are injected into the gaps where cracks are formed and solidified to prevent further cracking. When injecting the chemical solution, a separate pumping device is used.

As a device for injecting a chemical solution containing epoxy, several technologies are known, such as Korean Utility Model Registration Utility Model Publication No. 20-0237684 and No. 0121552. The former is for discharging the two-component chemical from the liquid container at the proper mixing ratio. The latter is for improving the structure of the driving device, which facilitates assembly disassembly and the easy cleaning after use. This is to reduce the damage of the possible device.

However, in the case of known devices, since all of them have a structure in which the chemical liquid can be pumped only in one direction, when the chemical liquid is solidified in the apparatus and the chemical flow path of the chemical liquid is blocked, the apparatus cannot be used and thus is not effective in use. In addition, due to the structural disadvantage that the drug solution can only be pumped in one direction, there is a problem that cannot use different types of drug solution at the same time.

The object of the present invention is not only easy to assemble and disassemble through the overall structure improvement of the device, but also easy to clean and maintain, thereby reducing the burnout of the device, while repairing chemicals including epoxy are pumped in both directions, or It is to provide a pumping device for injecting a liquid medicine so that it can be selectively adjusted such as pumped in one direction.

Another object of the present invention is to provide a pumping device for injecting a chemical liquid to improve the overall working efficiency by increasing the workability and shorten the working time, which is convenient for use.

As shown in Figure 1 and 2, the pumping device for injection of the chemical solution according to the present invention, the motor 10 for generating power, and is detachably coupled to each other through a fastening means (not shown) such as various bolts, etc. It has an upper plate 20, a middle plate 26, and a lower base 40.

The motor 10 is a means for generating power to the present pumping device and operates when power is applied through a separate power cable 12 to rotate the rotating shaft 10a. The side of the motor 10 is provided with a separate switch (not shown) for turning on / off the applied power.

The motor 10 is mounted to the top plate 20. Therefore, the upper plate 20 is provided with a mounting portion 22 for mounting in the rotation shaft 10a region of the motor 10. When the motor 10 is disposed in the mounting unit 22, a separate dummy block 24 is fastened to one side of the upper plate 20 so that the motor 10 may be fixed to the upper plate 20.

A separate middle plate 26 is interposed between the upper plate 20 and the lower base 40 to be described later in detail. A gear means (not shown) is provided between the upper plate 20 and the middle plate 26 to transmit the rotational force from the motor 10 to rotate the crank 32 to be described later.

The gear means includes a rotary boss 27 to which the rotary shaft 10a of the motor 10 is coupled and rotates, and a pinion 28 to which the rotary boss 27 is coupled to rotate with the rotary shaft 10a of the motor 10. , A driven gear 29 geared to and rotated on the outer surface of the pinion 28. The driven gear 29 is formed relatively large compared to the diameter of the pinion 28. Of course, a separate bearing 30 is further interposed between the pinion 28 and the driven gear 29.

Accordingly, when the motor 10 operates to rotate the rotation shaft 10a, the pinion 28 rotates in conjunction with the rotation shaft 10a to rotate the driven gear 29. Therefore, the rotation speed formed in the driven gear 29 is decelerated compared with the rotation speed formed in the rotation shaft 10a of the first motor 10.

The crank 32 is provided in the lower part of the gear means. The crank 32 serves to convert the linear reciprocating motion of the slide ram 42 provided in the lower base 40 to the rotary motion formed in the driven gear 29.

As shown in FIG. 3, the crank 32 includes a disc shaped crank body 33 and a pair of protrusions 34a and 34b protruding from each other on both sides of the crank body 33 with respect to the center. have. The upper protrusion 34a is coupled to the gear means and the lower protrusion 34b is fitted to the player bearing 36 mounted on the slide base 44.

Meanwhile, referring to FIGS. 3 and 4 including FIGS. 1 and 2, the lower part of the middle plate 26 supports the present pumping device as a whole while being detachably coupled with the upper plate 20 and the middle plate 26. The lower base 40 is provided. The lower base 40 is coupled to a stand 38 having a handle portion 38a formed therein to support the device as a whole.

Four support legs 41 are provided in the outer region of the lower base 40 to support the lower base 40 with respect to the ground. Although not shown in the figure, the support leg 41 is provided with anti-vibration rubber for absorbing vibration.

The lower base 40 has a through hole 40a through which a portion of the slide ram 42 and the slide base 44 coupled to the slide ram 42 are exposed. As the slide base 44 is exposed through the through hole 40a, the lower protrusion 34b of the crank 32 may be coupled to the player bearing 36 mounted on the slide base 44.

As described above, in the lower base 40, a rod-shaped slide ram 42 is disposed to penetrate the center region of the lower base 40. A slot 42a is formed on one surface of the slide ram 42, and the slide base 44 is coupled to the slot 42a in the form of a plate block. In the slide base 44, a player bearing 36 is mounted to operate the lower projection 34b of the crank 32 more smoothly.

A pair of first and second pump coupling portions 46a and 46b are formed on opposite sides of the lower base 40 along the longitudinal direction of the slide ram 42. First and second pumps 48a and 48b are coupled to the first and second pump coupling parts 46a and 46b, respectively.

First and second vessel coupling portions 49a and 49b are formed in the first and second pumps 48a and 48b to couple the first and second chemical liquid containers 50a and 50b, respectively. In the first and second chemical solution containers 50a and 50b coupled to the first and second container coupling parts 49a and 49b, a chemical solution such as an epoxy, which may be injected into a crack and coagulate, is accommodated. In this case, the chemical liquids accommodated in the first and second chemical liquid containers 50a and 50b may be the same or different from each other.

The first and second check valves 52a and 52b are provided in the first and second pumps 48a and 48b in the same configuration, respectively. The first and second check valves 52a and 52b have balls 53a and 53b for selectively opening and closing the chemical flow paths 51a and 51b and springs 55a and 55b for returning the balls 53a and 53b to their original positions. ) The springs 55a and 55b continuously press the balls 53a and 53b by compression springs so that the balls 53a and 53b always shield the moving passages 51a and 51b.

Meanwhile, first and second pumping bars 54a and 54b are disposed between the slide ram 42 and the first and second pumps 48a and 48b along the longitudinal direction of the slide ram 42. The first and second pumping bars 54a and 54b are disposed in the moving passages 51a and 51b of the corresponding first and second pumps 48a and 48b, respectively. When the slide ram 42 moves in a straight reciprocating motion, the balls 53a and 53b open the moving flow paths 51a and 51b by pressing the corresponding balls 53a and 53b while performing a linear reciprocating motion together. Allow it to be pumped.

At the ends of the first and second pumps 48a and 48b, first and second diaphragm gauges 56a and 56b for measuring pressure on the chemical liquid pumped through the first and second pumps 48a and 48b are provided. Are combined. First and second hoses 57a and 57b are coupled to the first and second diaphragm gauges 56a and 56b, respectively, and first and second ends of the first and second hoses 57a and 57b. The first and second pipes 61a and 61b are coupled through the two nipples 59a and 59b, and the first and second nozzles in which the chemical liquid is actually injected to the ends of the first and second pipes 61a and 61b. The tips 63a and 63b are coupled.

The operation of the chemical liquid injection pumping device having such a configuration will be described below with reference to FIGS. 4 and 5A and 5B.

The switch is operated in a state in which power is connected to the power cable 12 of the motor 10 to operate the motor 10 by the applied power. Then, as the rotation shaft 10a of the motor 10 starts to rotate, the pinion 28 associated with the rotation shaft 10a is rotated, and the pinion 28 rotates the driven gear 29.

When the driven gear 29 rotates, the crank 32 connected to the driven gear 29 and its upper projection 34a starts to rotate. The lower protrusion 34b of the crank 32 is fixed to the slide base 44 through the player bearing 36, so that when the crank 32 rotates, the slide ram 42 makes a linear reciprocating motion. do.

First, when the slide ram 42 linearly moves toward the first pump 48a, the first pumping bar 54a is pressed. Since the first pumping bar 54a is located in the chemical liquid flow passage 51a in the first pump 48a, the first pumping bar 54a moves and pushes the ball 53a. Then, as the spring 55a is compressed, the ball 53a is pushed to form a space therebetween and the pressure is lowered (see FIG. 5A). Therefore, the chemical liquid in the first chemical container 50a is transferred to the first diaphragm gauge 56a, the first hose 57a, the first nipple 59a, and the first via the moving passage 51a in the first pump 48a. After passing through the first pipe (61a) in turn may be injected through the first nozzle tip (63a).

When the slide ram 42 linearly moves toward the second pump 48b by the rotation of the crank 32 continuously, the pressing force of the ball 53a by the first pumping bar 54a is released. The ball 53a shields the movement flow path 51b of the chemical liquid by the spring 55a (see FIG. 5B). Therefore, the injection of the chemical liquid through the first nozzle tip 63a is stopped.

Instead, when the slide ram 42 linearly moves toward the second pump 48b, this time presses the second pumping bar 54b located on the side of the second pump 48b. As shown in FIG. 4, since the second pumping bar 54b is located in the chemical liquid flow passage 51b in the second pump 48b, the second pumping bar 54b moves and pushes the ball 53b. . Then, as the ball 53b is pushed, a space is formed and the pressure is lowered. Therefore, the chemical liquid in the second chemical container 50b passes through the second diaphragm gauge 56b, the second hose 57b, the second nipple 59b, and the second via the moving passage 51b in the second pump 48b. After passing through the two pipes (61b) in turn may be injected through the second nozzle tip (63b).

Of course, when the slide ram 42 linearly moves toward the first pump 48a by the rotation of the crank 32 again, the injection of the chemical liquid through the second nozzle tip 63b is stopped and the first nozzle tip 63a is stopped. Injection of the chemical liquid through begins.

In the case of the present invention, there is an advantage that the chemical liquid to both the first and second pumps 48a and 48b can be pumped only by rotating the crank 32. In addition, even if the chemical liquid is solidified and the moving flow paths 51a and 51b of any one of the first and second pumps 48a and 48b are shielded, the other side can be used. If the interior of any one of the first and the second chemical container (50a, 50b) is empty there is an additional advantage that can work while spraying the chemical in one direction (one direction).

As such, according to the present invention, since the assembly and disassembly are easy through the overall structural improvement of the apparatus, there is an advantage of easy cleaning and maintenance work. In addition, the chemical solution can be pumped to both the first and second pumps 48a and 48b, or can be selectively adjusted to be pumped to only one of the first and second pumps 48a and 48b. have.

As such, the pumping device is convenient for use, thereby increasing workability and reducing work time, thereby improving the overall work efficiency.

As described above, according to the pumping device for the injection of the chemical solution of the present invention, not only is easy to assemble and disassemble through the overall structural improvement of the device, but also easy to clean and maintain, reducing the damage of the device while repairing including epoxy Chemicals can be selectively adjusted, such as pumped in both directions or pumped in one direction.

In addition, according to the pumping device for the injection of the chemical solution of the present invention is convenient in use, the workability is increased and the working time is shortened, thereby improving the overall work efficiency.
