[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The utility model provides a technical solution: a grouting device for engineering construction, including a mobile platform 1, a grouting barrel 2 is fixedly installed on the mobile platform 1, a mounting hole 204 is opened on the grouting barrel 2, a heating rod 205 is installed with an inner thread of the mounting hole 204, a connecting hole 201 is opened in the grouting barrel 2, the connecting hole 201 is communicated with the inside of the mounting hole 204, a stirring motor 3 is fixedly installed under the mobile platform 1, a transmission shaft 301 is fixedly installed at the output end of the stirring motor 3, a sleeve 4 is sleeved on the transmission shaft 301, and a stirring shaft 404 is fixedly installed on the outer wall of the sleeve 4.

[0024] In this embodiment, the sleeve 4 is sleeved on the transmission shaft 301, so that when the device needs to be cleaned, starting the stirring motor 3 can drive the transmission shaft 301 to rotate, and the rotation of the transmission shaft 301 will drive the sleeve 4 to rotate, and the scraper installed on the sleeve 4 will scrape the inner wall of the grouting tube 2 clean. After completion, unscrew the fixing bolt 303 to release the restriction on the sleeve 4, and then the sleeve 4 can be directly pulled out from the transmission shaft 301, exposing the sleeve 4 completely to the outside world, so as to facilitate the cleaning of the limit bump 401 and the scraper, and the installation hole 204 The port is threaded so that the heating rod 205 can be threadedly installed in the mounting hole 204. In order to facilitate the disassembly and assembly of the heating rod 205, the inner diameter of the mounting hole 204 is larger than the diameter of the heating rod 205. After the heating rod 205 is damaged, it can be directly unscrewed and replaced. At the same time, the heating rod 205 does not directly contact the inner wall of the mounting hole 204. At this time, a certain amount of heat conductive medium needs to be added to the inside of the mounting hole 204 through the connecting hole 201, so that the heat generated by the heating rod 205 can be quickly transferred to the grouting tube 2 to heat the slurry inside the grouting tube 2.

[0025] Among them, in order to achieve the purpose of adding heat-conducting medium into the connecting hole 201, the present device is implemented by the following technical solution: a pump 101 is fixedly installed under the mobile platform 1, one end of the pump 101 is communicated with the interior of the grouting cylinder 2, a filling port 202 is fixedly installed on the outer wall of the grouting cylinder 2, the filling port 202 is communicated with the interior of the connecting hole 201, and a sealing plug 203 is installed on the inner thread of the filling port 202.

[0026] By starting the pump 101, the slurry inside the grouting barrel 2 can be pumped. The filling port 202 is connected to the inside of the connecting hole 201. After unscrewing the sealing plug 203, a certain amount of heat-conducting medium can be added to the inside of the connecting hole 201 through the filling port 202. After screwing on the sealing plug 203, the filling port 202 can be re-sealed.

[0027] Among them, in order to achieve the purpose of putting the sleeve 4 on the transmission shaft 301, the present device adopts the following technical scheme: a threaded hole 302 is opened at the upper end of the transmission shaft 301, and a fixing bolt 303 is installed in the threaded hole 302. A limiting protrusion 401 is fixedly installed on the inner wall of the sleeve 4, and a limiting groove is opened on the outer wall of the transmission shaft 301. The limiting groove and the limiting protrusion 401 cooperate with each other. A connecting rod 402 is fixedly installed on the outer wall of the sleeve 4, and a side wall scraper 403 is fixedly installed on the other end of the connecting rod 402. A bottom scraper 405 is fixedly installed on the outer wall of the sleeve 4 and near the lower end edge.

[0028] The sleeve 4 can be squeezed and fixed on the transmission shaft 301 through the fixing bolt 303. The limiting groove and the limiting protrusion 401 cooperate with each other to make the sleeve 4 stuck on the transmission shaft 301, thereby preventing the transmission shaft 301 from rotating and the sleeve 4 and the stirring motor 3 from sliding. The side wall scraper 403 and the bottom scraper 405 can scrape off the slurry adhering to the inner wall of the grouting tube 2, and the stirring shaft 404 can stir the slurry inside the grouting tube 2 to prevent the slurry from solidifying.

[0029] The working principle and use process of the utility model are as follows: when in use, the device needs to be placed in a suitable position, the slurry is poured into the grouting barrel 2, the stirring motor 3 is started to drive the transmission shaft 301 to rotate, the rotation of the transmission shaft 301 can drive the sleeve 4 to rotate, and the rotation of the sleeve 4 will drive the stirring shaft 404 to rotate, thereby continuously stirring the slurry inside the grouting barrel 2. At the same time, when the temperature is too low, the heating rod 205 can be started to heat the grouting barrel 2, and the pump 101 can be started to pump the slurry inside the grouting barrel 2 to the appropriate position for grouting operation.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
