Description

Technical Field

[0001] This application relates to the field of grouting equipment, and in particular to a cement grouting machine. Background Technology

[0002] Cement grouting machines are devices that inject cement grout into strata, structural cracks, or prefabricated sleeves. They are used in reinforcement projects such as foundation improvement and reinforcement, repair of concrete structures, leak sealing, filling of voids, and improvement of strata stability and bearing capacity. Cement grouting machines can improve construction quality and efficiency, and can also reduce costs to a certain extent.

[0003] Currently, cement grouting machines mainly include a grouting pump (the core component for pumping cement slurry), an inlet pipe for conveying cement slurry into the grouting pump, an outlet pipe for delivering cement slurry from the grouting pump to the target location, a control valve for regulating the slurry flow and pressure during the grouting process, as well as a pressure transmitter and an electromagnetic flowmeter. When grouting at a target location, the grouting machine is first moved to the vicinity of the target location. Then, the grouting pipe is connected to the grouting unit. Subsequently, the cement slurry is drawn in from the inlet pipe by the grouting pump, pressurized, and then delivered to the target location through the outlet pipe. However, grouting machines are not only heavy and equipped with many scattered parts, making them inconvenient to move and transport to the target location during construction, but they also generate severe vibrations during operation, especially when the operating horsepower is high. During vibration, the machine body may move along with the grouting pipe, easily disconnecting the connection between the grouting pipe and the grouting unit, making overall use inconvenient. Utility Model Content

[0004] To improve the ease of use and construction efficiency of cement grouting machines, this application provides a cement grouting machine.

[0005] This application provides a cement grouting machine, which adopts the following technical solution:

[0006] A cement grouting machine, comprising:

[0007] The frame includes a grouting pump, an inlet pipe and an outlet pipe detachably connected to the grouting pump, a control valve on the outlet pipe, and casters at the bottom of the frame; it also includes:

[0008] A positioning component is mounted on the frame. The positioning component includes a buffer component and a lifting component, wherein the buffer component is used to absorb the vibration generated by the grouting pump; and the lifting component is used to drive the buffer component to move up and down.

[0009] A storage component is disposed between the frame and the discharge pipe for storing the discharge pipe.

[0010] By adopting the above technical solution, when performing grouting operations at the target construction site using a cement grouting machine, the machine is first moved to the location using the casters at the bottom of the frame. Then, the lifting mechanism moves the buffer component downwards until it contacts the ground. Next, the inlet and outlet pipes are connected to the grouting pump, and the pump and control valve are started. Cement grout is drawn in through the inlet pipe and, under the pressure of the pump, is pushed to the outlet pipe. The outlet pipe delivers the pressurized grout to the target location, such as in the strata, structural cracks, or prefabricated sleeves. During the grouting process, the buffer component of the positioning assembly absorbs the vibration generated by the grouting pump, reducing the vibration on the frame. The machine is swayed to ensure the stability and continuity of the grouting operation. After grouting is completed, the control valve is closed and the grouting pump is stopped. Then, the grout pipe is organized and stored using the collection component to avoid pipe clutter and facilitate the organization and storage of the grout pipe. Subsequently, the buffer component is moved upward by the lifting component to separate it from the ground. The moving wheels added to the bottom of the frame, together with the lifting component, make the grouting machine more flexible to move on the construction site, reduce the burden of manual handling, and make it more convenient to use. At the same time, the buffer component in the positioning component, together with the lifting component, can effectively absorb the vibration generated by the grouting pump during operation, avoid violent shaking of the machine body, and improve the stability, continuity and construction efficiency of the grouting operation.

[0011] Optionally, the buffer component includes:

[0012] A base is disposed at the bottom of the frame, and a buffer groove is provided inside the base;

[0013] A buffer plate is disposed within the buffer groove and connected to the lifting component;

[0014] Multiple damping cylinders are spaced apart between the buffer plate and the bottom of the buffer groove, and a buffer spring is fitted on the outside of each damping cylinder.

[0015] By adopting the above technical solution, when the buffer component absorbs the vibration generated during the operation of the grouting pump, the buffer plate is first moved downward by the lifting component until the buffer plate touches the ground. When the grouting pump starts and generates vibration, the vibration is transmitted from the frame to the buffer plate. On the one hand, the damping cylinder absorbs the vibration energy through the internal damping material, and on the other hand, the buffer spring further absorbs the vibration energy through elastic deformation, thereby reducing the shaking of the frame.

[0016] Optionally, the lifting component includes:

[0017] The lifting screw is threaded to the frame, and one end is rotatably connected to the buffer plate;

[0018] The lifting guide rod is fixed at one end to the buffer plate and slidably connected to the frame at the other end.

[0019] By adopting the above technical solution, construction workers can rotate the lifting screw to move the buffer plate downwards or downwards under the action of the lifting guide rod, thereby controlling the base of the buffer component to contact or separate from the ground.

[0020] Optionally, an anti-loosening washer is fitted on the outside of the lifting screw, and an anti-loosening nut is threadedly connected to the outside of the lifting screw. The anti-loosening washer is located between the anti-loosening nut and the frame.

[0021] By adopting the above technical solution, the anti-loosening washer usually has a certain elasticity and can provide additional friction. When the lifting screw is vibrated, the anti-loosening washer can be locked between the nut and the frame to reduce the loosening of the threaded connection and prevent the threaded connection of the lifting screw from loosening due to vibration or long-term use during the operation of the grouting machine.

[0022] Optionally, a counterweight is fixedly provided below the base, and the bottom of the counterweight is provided with anti-slip texture.

[0023] By adopting the above technical solution, the counterweight increases the weight of the base, thereby improving the center of gravity distribution and stability of the entire grouting machine. At the same time, the anti-slip texture on the bottom increases the friction between the base and the ground, making it easier to maintain the stability of the equipment and reduce slippage in wet or muddy construction environments.

[0024] Optionally, the outer side of the movable wheel is fitted with an elastic rubber pneumatic tire.

[0025] By adopting the above technical solutions, the elastic rubber pneumatic tire has good shock absorption performance and can also absorb some of the vibration impact transmitted from the frame. When used in conjunction with the buffer components, the elastic rubber pneumatic tire can further absorb and disperse the vibration impact force generated by the grouting pump, thereby improving the stability and shock absorption effect of the cement grouting machine.

[0026] Optionally, multiple grout outlet pipes are provided, and each of the multiple grout outlet pipes is detachably connected to the grouting pump.

[0027] By adopting the above technical solutions, construction personnel can flexibly adjust the number and layout of grout outlet pipes according to actual construction needs. Multiple grout outlet pipes can simultaneously perform grouting operations on different construction sites at the target location, improving construction efficiency and flexibility, and shortening the overall construction cycle.

[0028] Optionally, the storage component includes:

[0029] A rotating shaft is rotatably connected to the frame.

[0030] The winding reel is slidably sleeved on the outside of the rotating shaft, and the slurry outlet pipe is wound around the outside of the winding reel;

[0031] A locking seat is fixed to the frame;

[0032] The locking rod is slidably connected to the locking seat and has a certain sliding resistance with the locking seat. The rotating shaft is provided with a plurality of locking holes spaced apart along its circumference, and one end of the locking rod can be inserted into the locking hole.

[0033] By adopting the above technical solution, when it is necessary to store the slurry tube, the construction personnel first rotate the rotating shaft to drive the winding reel to rotate. The slurry tube is wound around the outside of the winding reel as the winding reel rotates, achieving orderly storage. After the slurry tube is stored, the locking rod is pushed into the locking hole on the rotating shaft to lock the winding reel, thereby preventing the winding reel from rotating freely in the non-operational state and making the slurry tube more stable in the stored state.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. After grouting is completed, construction personnel can use the storage components to organize and store the grout pipes, avoiding messy pipes and facilitating the organization and storage of the grout pipes. The moving wheels added to the bottom of the frame, together with the lifting components, make the grouting machine more flexible to move on the construction site, reduce the burden of manual handling, and make the cement grouting machine more convenient to use.

[0036] 2. The buffer components in the positioning assembly, together with the lifting components, can effectively absorb the vibration generated during the operation of the grouting pump, avoid violent shaking of the machine body, and improve the stability, continuity and construction efficiency of the grouting operation;

[0037] 3. The counterweight in the buffer component increases the weight of the base, improving the center of gravity distribution and stability of the entire grouting machine. At the same time, the anti-slip texture on the bottom increases the friction between the base and the ground, making it easier to keep the equipment stable and reduce slippage in wet or muddy construction environments.

[0038] 4. Elastic rubber pneumatic tires have good shock absorption performance and can also absorb some of the vibration and impact transmitted from the frame. When used in conjunction with buffer components, elastic rubber pneumatic tires can further absorb and disperse the vibration and impact force generated by the grouting pump, thereby improving the stability and shock absorption effect of the cement grouting machine.

[0043] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0044] After reading this specification, those skilled in the art may make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] This application discloses a cement grouting machine. (Refer to...) Figure 1 and Figure 2 The cement grouting machine includes a frame 1, on which a grouting pump 2 is mounted. The grouting pump 2 has an inlet pipe 3 and multiple outlet pipes 4, and the grouting pump 2 is detachably connected to the inlet pipe 3 and the multiple outlet pipes 4 via unions 5. A control valve 6 is installed on the outlet pipe 4, and casters 7 are also installed at the bottom of the frame 1. A positioning assembly 8 is mounted on the frame 1, including a buffer component 81 for absorbing vibrations generated by the grouting pump 2 and a lifting component 82 for moving the buffer component 81 up and down. A receiving assembly 9 is located between the frame 1 and the outlet pipes 4 to receive the outlet pipes 4.

[0047] When performing grouting operations at the target construction site using a cement grouting machine, the machine is first moved to the location using the casters 7 at the bottom of the frame 1. Then, the lifting component 82 moves the buffer component 81 downwards, bringing it into contact with the ground. Next, the inlet pipe 3 and outlet pipe 4 are connected to the grouting pump 2 via the union joint 5, and the pump 2 and control valve 6 are activated. Cement grout is drawn in through the inlet pipe 3 and, under pressure from the pump 2, is pushed to the outlet pipe 4. The outlet pipe 4 then delivers the pressurized grout to the target location, such as in the strata, structural cracks, or prefabricated sleeves. During grouting, the buffer component 81 of the positioning assembly 8 absorbs the vibration generated by the pump 2, reducing frame 1 sway and ensuring the stability and continuity of the grouting operation.

[0048] After grouting is completed, the control valve 6 is closed and the grouting pump 2 is stopped. Then, the grout outlet pipe 4 is organized and stored using the storage component 9 to prevent pipe clutter and facilitate the organization and storage of the grout outlet pipe 4. Subsequently, the lifting component 82 moves the buffer component 81 upwards to separate it from the ground. The casters 7 added to the bottom of the frame 1, in conjunction with the lifting component 82, make the grouting machine more flexible to move on the construction site, reducing the burden of manual handling and making it more convenient to use. At the same time, the buffer component 81 in the positioning component 8, in conjunction with the lifting component 82, effectively absorbs the vibration generated by the grouting pump 2 during operation, preventing violent shaking of the machine body and improving the stability, continuity, and construction efficiency of the grouting operation. Construction personnel can also flexibly adjust the number and layout of the grout outlet pipes 4 according to actual construction needs, and multiple grout outlet pipes 4 can simultaneously perform grouting operations on different locations at the target site, improving construction efficiency and flexibility, and shortening the overall construction cycle.

[0049] Reference Figure 2 and Figure 3The buffer component 81 includes a base 811 located at the bottom of the frame 1, with a buffer groove 8111 inside the base 811. A buffer plate 812 is installed inside the buffer groove 8111 and is connected to the lifting component 82. Multiple damping cylinders 813 are spaced apart between the buffer plate 812 and the bottom of the buffer groove 8111, and each damping cylinder 813 is fitted with a buffer spring 814. A counterweight 815 is fixed below the base 811, with anti-slip texture on its bottom. The counterweight 815 increases the weight of the base 811, improving the center of gravity distribution and stability of the entire grouting machine. Simultaneously, the anti-slip texture on the bottom increases the friction between the base 811 and the ground, making it easier to maintain the stability of the grouting machine and reduce slippage in wet or muddy construction environments. The outer side of the moving wheel 7 is fitted with an elastic rubber pneumatic tire 816. The elastic rubber pneumatic tire 816 has good shock absorption performance and can also absorb some of the vibration impact transmitted from the frame 1. The elastic rubber pneumatic tire 816 is used in conjunction with the buffer component 81 to further absorb and disperse the vibration impact force generated by the grouting pump 2.

[0050] When the grouting pump 2 absorbs vibrations during operation through the buffer component 81, the buffer plate 812 is first moved downwards by the lifting component 82 until it contacts the ground. When the grouting pump 2 starts and generates vibrations, the vibrations are transmitted from the frame 1 to the buffer plate 812. On the one hand, the damping cylinder 813 absorbs the vibration energy through its internal damping material, and on the other hand, the buffer spring 814 further absorbs the vibration energy through elastic deformation, thereby reducing the swaying of the frame 1.

[0051] Reference Figure 2 and Figure 3 The lifting component 82 includes a lifting screw 821 threadedly connected to the frame 1. The lifting screw 821 is vertically oriented, and its bottom end is rotatably connected to a buffer plate 812. A handwheel 822 is fixedly mounted on the top of the lifting screw 821. Two lifting guide rods 823, parallel to the lifting screw 821, are fixedly mounted on the top of the buffer plate 812. The tops of the lifting guide rods 823 are slidably connected to the frame 1. An anti-loosening washer 824 is sleeved on the outside of the lifting screw 821, and an anti-loosening nut 825 is threadedly connected to the outside of the lifting screw 821. The anti-loosening washer 824 is located between the anti-loosening nut 825 and the frame 1.

[0052] Construction workers rotate handwheel 822, which drives the lifting screw 821 to rotate. Under the action of lifting guide rod 823, the buffer plate 812 moves downward or downward, thereby controlling the base 811 in the buffer component 81 to contact or separate from the ground. The anti-loosening washer 824 usually has a certain degree of elasticity and can provide additional friction. When the lifting screw 821 is subjected to vibration, the anti-loosening washer 824 can lock between the nut and the frame 1, reducing loosening at the threaded connection and preventing the threaded connection of the lifting screw 821 from loosening due to vibration or long-term use during the operation of the grouting machine.

[0053] Reference Figure 3 The storage assembly 9 includes a rotating shaft 91 rotatably connected to the frame 1 in a vertical direction. A wheel 92 is provided at the top of the rotating shaft 91, and a splined shaft 93 is fixed on the side of the wheel 92 near the rotating shaft 91. A splined groove 911 is opened at the top of the rotating shaft 91, and the splined shaft 93 is inserted into the splined groove 911. A winding reel 94 is slidably sleeved on the outside of the rotating shaft 91, and the pulp outlet pipe 4 is wound around the outside of the winding reel 94. A locking seat 95 is fixed on the frame 1, and a locking rod 96 is slidably connected in the locking seat 95. There is a certain sliding resistance between the locking rod 96 and the locking seat 95. Multiple locking holes 912 are evenly spaced along the circumference of the rotating shaft 91, and one end of the locking rod 96 can be inserted into the locking hole 912.

[0054] When the discharge pipe 4 needs to be stored, the operator first rotates the rotating wheel 92. The rotating wheel 92 drives the winding reel 94 to rotate via the rotating shaft 91. As the winding reel 94 rotates, the discharge pipe 4 winds around to the outside of the winding reel 94, achieving orderly storage. After the discharge pipe 4 is stored, the locking rod 96 is pushed into the locking hole 912 on the rotating shaft 91 to lock the winding reel 94, thus preventing the winding reel 94 from rotating freely in a non-operating state and making the discharge pipe 4 more stable in the stored state. Furthermore, the winding reel 94 adopts a detachable design. When the discharge pipe 4 needs to be flushed, inspected, or maintained, the operator can pull the rotating wheel 92 upwards to remove the splined shaft 93 from the splined groove 911, and then remove the winding reel 94.

[0055] The implementation principle of a cement grouting machine according to this application embodiment is as follows: After grouting is completed, the control valve 6 is closed and the grouting pump 2 is stopped. Then, the grout outlet pipe 4 is organized and stored using the storage component 9 to avoid pipe clutter and facilitate the organization and storage of the grout outlet pipe 4. Subsequently, the lifting component 82 drives the buffer component 81 to move upward and separate it from the ground. The moving wheels 7 added to the bottom of the frame 1, together with the lifting component 82, make the grouting machine more flexible to move on the construction site, reduce the burden of manual handling, and make it more convenient to use. At the same time, the buffer component 81 in the positioning component 8, together with the lifting component 82, can effectively absorb the vibration generated by the grouting pump 2 during operation, avoid violent shaking of the machine body, and improve the stability, continuity, and construction efficiency of the grouting operation. Construction personnel can also flexibly adjust the number and layout of the grout outlet pipe 4 according to actual construction needs, and multiple grout outlet pipes 4 can simultaneously perform grouting operations on different construction sites at the target location, improving construction efficiency and flexibility, and shortening the overall construction cycle.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
