Description

TECHNICAL FIELD

[0001] The utility model relates to grouting device technical field, concretely relates to a grouting construction device. BACKGROUND

[0002] Grouting is to fill the cracks and pores in the rock-soil by pouring some solidified materials, such as cement, lime or other chemical materials, into the foundation rock-soil within a certain range, to prevent seepage of the foundation and improve the integrity, strength and stiffness of the rock-soil. In prefabricated buildings, grouting construction technology is also needed.

[0003] Through the search, patent announcement No. CN202222707571.1 discloses a grouting construction device. Although the device can fix the connecting head on the discharge pipe when in use, the accommodating part and the guide part for fixing the discharge pipe are arranged on the connecting head, the disc is fixedly connected to the connecting head, the screw part and the transmission part for providing power required for fixing the discharge pipe are arranged on the disc, and the device can automatically fix the connecting head and the grouting port without manual holding of the pipeline for grouting, thereby reducing manpower. However, the device does not have a structure for cooling the transmission mechanism of the high-pressure pumping machine when in use, and the temperature is relatively high when used for a long time. Since the device lacks a cooling structure, the transmission mechanism of the high-pressure pumping machine may generate a large amount of heat due to friction and mechanical operation when working for a long time, which may cause overheating of the mechanism. Overheating not only reduces the efficiency of the transmission mechanism, but also may cause equipment failure or damage. If the transmission mechanism stops or its performance decreases due to overheating, the progress and efficiency of the grouting construction will be directly affected, which may cause delay of the construction period or increase of the cost.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0035] Please refer to Figs. 1-3 The embodiments provided by the utility model:

[0036] Embodiment one:

[0037] The utility model provides a grouting construction device, including transmission case 5, motor 2 is installed on transmission case 5, and motor 2 is connected with transmission case 5 through transmission wheel 3 and driven wheel 4, and one side of transmission case 5 is installed with pump head 1 through sleeve 6, and the outer shell of pump head 1 is equipped with feed pipe 101 and discharge pipe 102, and the top of transmission case 5 is installed with cover plate 501, and motor 2 is installed on transmission case 5 through cover plate 501, and pump head 1 is equipped with pump core 104, and the cavity 107 between pump core 104 and the outer shell of pump head 1 is used for temporarily storing the medium into pump head 1, and one end of sleeve 6 is installed with conveying pipe 108 in pump head 1, and the through hole is set up on conveying pipe 108, and the mounting hole 106 is set up on pump core 104, and the taper guide block 105 is inlaid in mounting hole 106, and the taper guide hole 103 is set up in taper guide block 105, and the smaller end of taper guide hole 103 is towards the flow direction of medium, and then the taper guide hole 103 of taper guide block 105 plays the one-way flow guiding effect to medium, and the design of taper guide hole 103 not only realizes the one-way flow guiding of medium, but also enhances the flow velocity and pressure of medium through the gradually narrowing caliber. This design ensures that the medium can stably and efficiently pass through pump head 1, avoids backflow and leakage, thereby improving the efficiency and quality of grouting construction. Meanwhile, the structure of taper guide block 105 is simple, easy to manufacture and maintain, which reduces the cost of equipment, and the transmission case 5 is equipped with rotating shaft 7, and rotating shaft 7 is connected with driven wheel 4, and eccentric wheel 801 is installed on rotating shaft 7, and connecting rod 8 is installed on eccentric wheel 801, and the transmission mechanism realizes the effective energy transmission from motor 2 to piston head 10, so that piston head 10 can stably and continuously slide in conveying pipe 108. By adjusting the speed and direction of motor 2, the speed and direction of piston head 10 can be controlled, so as to realize the accurate control of medium flow. In addition, the design of eccentric wheel 801 and connecting rod 8 makes the transmission process more stable and reliable, reduces the vibration and noise of the equipment, and the limiting block 9 is installed in sleeve 6, and connecting rod 8 and piston head 10 are connected and fixed through limiting block 9, and the design of limiting block 9 ensures the stable connection between connecting rod 8 and piston head 10, avoids the equipment failure caused by loose or falling connection. At the same time, limiting block 9 can also limit the movement of connecting rod 8 and piston head 10 to prevent them from being damaged due to excessive movement. This design improves the reliability and durability of the equipment and reduces the maintenance cost. The piston head 10 slides in the conveying pipe 108, and the pressure generated by the movement of piston head 10 in the conveying pipe 108 cooperates with the mounting hole 106 to suck the medium into the conveying pipe 108 or send the medium out of the conveying pipe 108, and the sliding of piston head 10 in the conveying pipe 108 generates a pressure difference, which is the key to drive the flow of medium.By precisely controlling the speed and direction of the piston head 10, the flow of the medium can be precisely regulated. At the same time, the design of the mounting hole 106 allows the medium to smoothly enter and exit the pump head 1, avoiding equipment failure caused by flow channel blockage. This design not only improves the efficiency and quality of grouting construction, but also makes the equipment more easy to maintain and manage.

[0038] Example two:

[0039] To increase the cooling efficiency of the structure inside the sleeve 6, as shown in the example, Figs. 1-3 The utility model also includes: the heat exchange cavity 601 is set up in the sleeve 6, and connecting heads are set up on both sides of the heat exchange cavity 601, and the heat exchange medium is passed into the heat exchange cavity 601 through the connecting heads, and then the limiting block 9 in the sleeve 6 is cooled.

[0040] Working principle:

[0041] The medium enters the pump head 1 through the feed pipe 101 and is first temporarily stored in the cavity 107. This cavity 107 plays the role of buffering and storing the medium, ensuring that there is enough amount of medium before the pump core 104 starts working.

[0042] When the motor 2 starts, it drives the rotating shaft 7 to rotate through the transmission wheel 3 and the driven wheel 4. The eccentric wheel 801 on the rotating shaft 7 rotates and pulls the piston head 10 to slide in the delivery pipe 108 through the connecting rod 8. The sliding of the piston head 10 generates a pressure difference, which causes the medium to be sucked into the delivery pipe 108. When the piston head 10 slides in the opposite direction, the medium is compressed and sent out from the delivery pipe 108. The design of the conical guide block 105 and its conical guide hole 103 plays a key role. The smaller end of the conical guide hole 103 points towards the direction of the flow of the medium, which ensures that the medium can only flow in the predetermined direction, achieving one-way flow guiding.

[0043] The conical guide block 105 is installed on the pump core 104 and is equipped with a conical guide hole 103. The design of this conical guide hole 103 is very critical, with its smaller end pointing towards the direction of the flow of the medium. When the medium flows in from the larger end, it will be squeezed and accelerated due to the gradually narrowing flow channel. The pressure difference generated by this accelerated flow allows the medium to smoothly enter the delivery pipe 108. Once the medium enters the delivery pipe 108, it will become an obstacle to the continued flow of the medium due to the narrowing of the conical guide hole 103. At this time, if the medium tries to flow backward or leak, it will be blocked by the conical guide block 105, thus failing to achieve.

[0044] Motor 2 drives shaft 7 to rotate via a transmission system, which in turn drives eccentric wheel 801 and connecting rod 8 to move. This movement causes piston head 10 to slide back and forth within delivery pipe 108. When piston head 10 slides in one direction, it compresses the medium within delivery pipe 108, creating a pressure difference. This pressure difference draws the medium into delivery pipe 108. When piston head 10 slides in the opposite direction, it releases the previously compressed medium, creating a pressure difference in the other direction. This pressure difference sends the medium out of delivery pipe 108 for grouting operations.

[0045] After passing through a unidirectional guide, the medium is discharged through the discharge pipe 102 for grouting construction. During this process, the conical guide block 105 ensures the stable flow of the medium and avoids backflow or leakage.

[0046] The heat exchange chamber 601 and its connector within the sleeve 6 are designed to allow the introduction of a heat exchange medium. This heat exchange medium can be water, oil, or other suitable substances, used to absorb and remove heat from the sleeve 6 and its internal components. When the motor 2 and transmission system operate, they generate heat. This heat is transferred to the heat exchange medium within the heat exchange chamber 601 through components such as the sleeve 6 and the limiting block 9. During circulation, the heat exchange medium carries away the absorbed heat and dissipates it into the air or recovers it into the cooling system for reuse through heat dissipation devices (such as radiators, cooling towers, etc.) at the connector. By adjusting the flow rate, temperature, and circulation speed of the heat exchange medium, the temperature of the sleeve 6 and its internal components can be controlled. This temperature control mechanism helps prevent performance degradation or damage caused by overheating, extending the equipment's service life.
