Description

Technical Field

[0001] This application relates to the field of prefabricated building construction technology, and more specifically, to a quantitative pressure-stabilizing grouting device. Background Technology

[0002] The prefabricated building green construction grouting device is a specialized piece of equipment used in the green construction process of prefabricated buildings to grout prefabricated walls or connection points. Its main purpose is to improve the overall structural strength and stability by injecting appropriate grout material into the gaps and connection points of prefabricated buildings, allowing it to fill and solidify. However, existing prefabricated building green construction grouting devices cannot solve the problem of grout blockage, leading to reduced construction efficiency and grout treatment effectiveness.

[0003] In response, Chinese patent application number CN202422595191.2 discloses a green construction grouting device for prefabricated buildings. This solution mainly uses the setting of vibration components to effectively prevent grout from clogging in pipes or tanks. In this process, the spring can absorb and disperse part of the vibration energy transmitted by the vibrator, so that the spring moves with the vibration of the tank.

[0004] However, in the process of implementing the technical solution in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems: 1. The vibrator is only installed on the pressure tank, while the discharge pipe does not participate in the vibration, which can easily cause blockages in the pipe. 2. In actual construction, an air compressor is usually used to pressurize the tank to push the slurry out of the pipe. Due to the long pipe and the large damping of the slurry, the air pressure is not evenly transmitted in the pipe. When pressurization is turned on, the slurry will flow out with a delay. When pressurization is stopped, the residual pressure in the tank will still push the slurry out slowly. The pressure is not stable enough and affects the quantitative output of slurry. Utility Model Content

[0005] To overcome the above deficiencies, this application provides a quantitative pressure-stabilizing grouting device, which aims to improve the problems mentioned in the background art.

[0006] This application provides a quantitative pressure-stabilizing grouting device, including a trolley, a pressure tank on the trolley, a vibration mechanism on the pressure tank, a grouting hose connected to the outlet of the pressure tank, and a swing mechanism on the trolley, with the root of the hose sleeved on the swing mechanism.

[0007] In one specific implementation, the trolley includes a platform and casters, with the casters mounted at the four corners of the platform.

[0008] In one specific implementation, the cart further includes a handle, which is fixedly connected to the cart board.

[0009] In the above process, the trolley is pushed to the construction site. The casters have a self-locking structure, which makes the construction more stable.

[0010] In one specific implementation, the pressure tank includes a tank body and a shock absorber base. The shock absorber base is mounted on the vehicle panel, and the tank body is mounted on the shock absorber base. An air inlet is provided on the tank body.

[0011] In the above implementation process, the shock absorber is made of rubber, which can reduce the transmission of vibration from the mechanism to the trolley. The shock absorber is a conventional accessory, and its structure and principle are clear to those skilled in the art, so they will not be described in detail here.

[0012] In one specific implementation, the barrel body is provided with a barrel lid, the barrel lid is provided with a rubber gasket and is sealed to the barrel body, and a bolt is provided between the barrel body and the barrel lid.

[0013] In the above process, bolts are used to fix the lid to the barrel body, and rubber gaskets are used to improve the sealing and reduce vibration transmission.

[0014] In one specific implementation, the vibration mechanism includes a vibrating rod, which is fixedly connected to the inside of the bucket lid, and a vibration motor is provided outside the bucket lid.

[0015] In the above process, the vibration generated by the vibrating motor is transmitted to multiple vibrating rods. After the well-mixed slurry is poured into the tank, the air bubbles in the slurry can be reduced by vibration, which is beneficial to the stable transmission of pressure and the quality of grouting.

[0016] In one specific implementation, the swing mechanism includes a bracket, a motor, and a sleeve. The bracket is mounted on the vehicle plate, the motor is mounted on the bracket, an eccentric rod is fixedly connected to the output end of the motor, the flexible hose is fixedly inserted through the sleeve, and a linear groove is fixedly connected to the sleeve. The eccentric rod reciprocates within the groove.

[0017] In the above implementation process, the motor drives the eccentric rod to rotate, and the eccentric rod moves in a circular motion within the transverse groove, thereby driving the groove to reciprocate in a high-frequency, low-amplitude longitudinal motion, generating a sinusoidal vibration wave that can be transmitted along the hose, which helps to reduce the damping of the slurry in the hose. It should be noted that the hose can be tightened inside the sleeve after being filled with slurry, which is beneficial for vibration transmission. In this embodiment, in order to reduce the impact of hose vibration on the hand, a shock-absorbing rubber sleeve is provided at the front end of the hose, which can reduce hand vibration.

[0018] In one specific implementation, the groove is located at the front end of the sleeve, and the rear end of the sleeve is hinged to the bracket.

[0019] In the above implementation process, when the sleeve reciprocates, the rear end of the sleeve has a smaller amplitude due to the limitation of the hinge, which can reduce the impact of vibration waves on the hose interface, while the front end of the sleeve has a larger amplitude, which facilitates the transmission of vibration waves.

[0020] Compared with the prior art, the beneficial effects of this application are: the vibration mechanism can make the slurry in the pressure tank vibrate to reduce air; the swing mechanism can drive the hose to swing back and forth, generate a sine wave and transmit it along the hose, which helps to reduce the damping of the slurry in the hose, making the pressure transmission more stable, and the control delay of the air inlet on the slurry is smaller, which is conducive to the quantitative and stable transmission of slurry.

Detailed Implementation

[0024] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0025] Please see Figures 1-3This application provides a quantitative and pressure-stabilized grouting device, including a trolley 10, a pressure tank 20 mounted on the trolley 10, a vibration mechanism 30 mounted on the pressure tank 20, and a grouting hose 40 connected to the outlet of the pressure tank 20. The trolley 10 also includes a swing mechanism 50, with the root of the hose 40 fitted onto the swing mechanism 50. The vibration mechanism 30 vibrates the grout inside the pressure tank 20 to reduce air pressure; the swing mechanism 50 drives the hose 40 to swing back and forth, generating a sine wave that is transmitted along the hose 40, which helps reduce damping of the grout in the hose 40, making pressure transmission more stable. The control delay of the air inlet 23 on the grout is also smaller, which is beneficial for the quantitative and stable transmission of the grout.

[0026] Please see Figures 1-3 The trolley 10 includes a platform 11 and casters 12, which are installed at the four corners of the platform 11. The trolley 10 also includes a handle 13, which is fixedly connected to the platform 11. When the trolley 10 is pushed to the construction site, the casters 12 have a self-locking structure, which can make the construction more stable by self-locking.

[0027] Please see Figures 1-3 The pressure tank 20 includes a tank body 21 and a shock absorber 22. The shock absorber 22 is mounted on the cart 11, and the tank body 21 is mounted on the shock absorber 22. An air inlet 23 is provided on the tank body 21. The shock absorber 22 is made of rubber and can reduce the transmission of vibration from the vibration mechanism 30 to the trolley 10. The shock absorber 22 is a conventional accessory, and its structure and principle are clear to those skilled in the art, so they will not be described in detail here.

[0028] Please see Figures 1-3 A lid 24 is provided on the barrel body 21, and a rubber gasket 25 is provided on the lid 24 to seal it to the barrel body 21. A bolt 26 is provided between the barrel body 21 and the lid 24. The bolt 26 is used to fix the lid 24 to the barrel body 21, and the rubber gasket 25 is used to improve the sealing performance and reduce vibration transmission.

[0029] Please see Figures 1-3 The vibration mechanism 30 includes a vibrating rod 31, which is fixedly connected to the inside of the bucket cover 24. A vibration motor 32 is installed outside the bucket cover 24. The vibrating rod 31 is made of hollow die-cast aluminum alloy. The vibration generated by the vibration motor 32 is transmitted to multiple vibrating rods 31. After the well-mixed slurry is poured into the bucket body 21, the air bubbles in the slurry can be reduced by vibration, which is beneficial to the stable transmission of pressure and the quality of grouting.

[0030] Please see Figures 1-3The swing mechanism 50 includes a bracket 51, a motor 52, and a sleeve 53. The bracket 51 is mounted on the vehicle plate 11, and the motor 52 is mounted on the bracket 51. An eccentric rod 54 is fixedly connected to the output end of the motor 52. A flexible tube 40 is fixedly inserted through the sleeve 53, and a linear groove 55 is fixedly connected to the sleeve 53. The eccentric rod 54 reciprocates within the groove 55. The motor 52 drives the eccentric rod 54 to rotate, and the eccentric rod 54 moves in a circular motion within the transverse groove 55, thereby driving the groove 55 to reciprocate longitudinally at a high frequency and low amplitude. This generates a sinusoidal vibration wave that can be transmitted along the flexible tube 40, which helps reduce the damping of the slurry in the flexible tube 40. It should be noted that the flexible tube 40 can be tightened within the sleeve 53 after being filled with slurry, which is beneficial for vibration transmission. In this embodiment, to reduce the impact of the vibration of the flexible tube 40 on the hand, a shock-absorbing rubber sleeve is provided at the front end of the flexible tube 40 to reduce hand vibration.

[0031] Please see Figures 1-3 The groove 55 is located at the front end of the sleeve 53, and the rear end of the sleeve 53 is hinged to the bracket 51. When the sleeve 53 reciprocates, the rear end of the sleeve 53 has a smaller amplitude due to the hinge, which can reduce the impact of vibration waves on the hose 40 interface, while the front end of the sleeve 53 has a larger amplitude, which facilitates the transmission of vibration waves.

[0032] The working principle of this quantitative and pressure-stabilizing grouting equipment is as follows: The trolley 10 is pushed to the construction site. The universal wheels 12 adopt a self-locking structure, which can achieve more stable self-locking construction. After the mixed grout is poured into the barrel 21, the barrel cover 24 is fixed on the barrel 21. The vibration generated by the vibration motor 32 is transmitted to multiple vibrating rods 31. The air bubbles in the grout can be reduced by vibration, which is conducive to stable pressure transmission and grouting quality. The valve on the air inlet 23 is opened, so that the high-pressure air from the air compressor is transmitted into the barrel 21, pushing the grout out from the hose 40. The motor 52 drives the eccentric rod 54 to rotate. The eccentric rod 54 moves in a circular motion in the transverse slide groove 55, thereby driving the slide groove 55 to move longitudinally at high frequency and low amplitude. The vibration wave can be transmitted along the hose 40, which helps to reduce the damping of the grout in the hose 40, making the pressure transmission more stable. The control delay of the air inlet 23 on the grout is smaller, which is conducive to the quantitative and stable transmission of grout.

[0033] In summary, the vibration mechanism 30 can cause the slurry in the pressure tank 20 to vibrate in order to reduce air; the swing mechanism 50 can drive the hose 40 to swing back and forth, generate a sine wave and transmit it along the hose 40, which helps to reduce the damping of the slurry in the hose 40, making the pressure transmission more stable, and the control delay of the air inlet 23 on the slurry is smaller, which is conducive to the quantitative and stable transmission of slurry.

[0034] The vibration motor 32 and the electric motor 52 involved in this application are each equipped with a corresponding switch. The vibration motor 32 and the electric motor 52 are general-purpose devices, and their power supply and control are general technologies, so they will not be described redundantly.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, improvements, or equivalent substitutions made within the spirit and principles of this application should be included within the scope of protection of this application.
