Description

Technical Field

[0001] The present application relates to the technical field of mortar mixing equipment, and in particular to an adaptive lubricating pump mortar transport mixing tank. Background Art

[0002] Ready-mix concrete pumping technology is widely used in construction, especially in high-rise and super-high-rise building construction, where its convenience and efficiency are particularly important. To ensure smooth pumping, the pump pipe must be wetted and lubricated before pumping concrete to reduce friction between the concrete and the pump pipe, thereby avoiding potential problems during the pumping process.

[0003] At present, in order to solve the problem of wetting and lubricating the pump pipe before concrete is pumped, the existing technical means are usually to use tank trucks to transport the pump-lubricating mortar to the construction site and use the pump-lubricating mortar to wet and lubricate the pump pipe. During the transportation process, in order to prevent the pump-lubricating mortar from stratifying or adhering to the inner wall of the storage tank, the pump-lubricating mortar usually needs to be stirred.

[0004] Existing mixing tanks for transporting lubricating pump mortar usually use a stirring rod to stir the lubricating pump mortar. However, when the lubricating pump mortar enters the mixing tank, some heavier materials in the lubricating pump mortar will first sink to the bottom, causing the stirring rod to be unable to rotate when starting due to excessive resistance from the materials that sink to the bottom of the lubricating pump mortar. Even if the stirring rod can rotate normally, the uniformity of the mixing of the lubricating pump mortar is poor. Utility Model Content

[0024] The following will be combined with the Figure 1 -Attached Figure 4 The technical solutions in the embodiments of the present invention are clearly and completely described. The described embodiments are only possible technical implementations of the present invention and do not constitute a complete set of implementations. Those skilled in the art can combine the embodiments of the present invention to derive other embodiments without inventive work, and such embodiments are also within the scope of protection of the present invention.

[0025] The inventors of this application have discovered that when the stirring rod of an existing mixing tank for transporting wet pump mortar is started, it cannot rotate normally due to the excessive resistance of the sediment in the wet pump mortar. Even if the stirring rod can rotate normally, the uniformity of the mixing of the wet pump mortar is poor. Therefore, this application discloses an adaptive mixing tank for transporting wet pump mortar, which mainly adopts the following solutions:

[0026] The embodiment of the present application discloses an adaptive lubricating pump mortar transport mixing tank. Figure 1 , including a tank body 1 and a rotating shaft 2 rotatably arranged in the tank body 1, a feed port 11 is opened on the top wall of the tank body 1, a discharge pipe 12 is connected to the position near the bottom of the tank body 1, a valve 13 is provided on the storage tank, a stirring rod 21 is slidingly sleeved on the rotating shaft 2, a shaft sleeve 22 is rotatably sleeved on the stirring rod 21, and a plurality of stirring blades 23 are fixedly arranged on the shaft sleeve 22, and the stirring blades 23 are distributed at equal intervals along the circumference of the shaft sleeve 22.

[0027] Reference Figure 1 、 2 A power unit for driving the rotating shaft 2 to rotate is provided on the tank body 1, and the power unit includes a servo motor 14. The servo motor 14 is fixedly arranged on the top of the tank body 1. A driving gear 141 is coaxially fixed on the output shaft of the servo motor 14, and a driven gear 24 is coaxially fixed on the rotating shaft 2. The driving gear 141 is engaged with the driven gear 24; an electronic control system 15 is also installed on the tank body 1, and the electronic control system 15 is electrically connected to the servo motor 14 for controlling the opening and closing of the servo motor 14.

[0028] Reference Figure 1 、 3 , a guide bar 25 is fixedly provided on the side wall of the rotating shaft 2, and the length direction of the guide bar 25 is parallel to the length direction of the rotating shaft 2. A guide groove 211 is provided on the stirring rod 21 along the length direction of the stirring rod 21. The guide bar 25 is slidably arranged in the guide groove 211. A lifting control unit for driving the stirring rod 21 to slide is provided on the tank body 1. The lifting control unit includes a driving ring 212, a transmission rod 16 and a servo cylinder 17. The driving ring 212 is sleeved on the stirring rod 21 and is coaxially connected to the stirring rod 21 for rotation. The transmission rod 16 is slidably arranged in the tank body 1 along the length direction of the rotating shaft 2. The servo cylinder 17 is fixedly arranged on the top wall of the tank body 1, and the piston rod of the servo cylinder 17 extends into the tank body 1 and is fixedly connected to the transmission rod 16. The electronic control system 15 is electrically connected to the servo cylinder 17, and the servo cylinder 17 is driven to start by the electronic control system 15, and the stirring rod 21 is driven to move along the length direction of the rotating shaft 2 through the transmission rod 16. Since the drive ring 212 is coaxially connected to the stirring rod 21 for rotation, the stirring rod 21 can be driven to move up and down in the tank body 1 while the stirring rod 21 rotates.

[0029] Reference Figure 3The side wall of the stirring rod 21 is provided with a positioning groove 213 along the circumference of the stirring rod 21, and the positioning groove 213 is arc-shaped. A connecting block 221 is fixedly provided on the inner side wall of the sleeve 22, and the connecting block 221 is slidably set in the positioning groove 213. A resistance sensing unit is provided on the stirring rod 21, and the resistance sensing unit includes a pressure sensor 214. The pressure sensor 214 is fixedly set in the positioning groove 213 and abuts against the connecting block 221. The pressure sensor 214 is electrically connected to the electronic control system 15; when the rotating shaft 2 is driven to rotate, the stirring blade 23 is subjected to the resistance from the lubricating pump mortar and transmitted to the pressure sensor 214. The pressure sensor 214 detects the size of the resistance of the lubricating pump mortar on the stirring blade 23 in real time.

[0030] Reference Figure 3 、 4 , sealed bearings 215 are provided on the stirring rod 21 and on the upper and lower sides of the positioning groove 213. The inner ring of the sealed bearing 215 is fixedly connected to the stirring rod 21, and the outer ring of the sealed bearing 215 is fixedly connected to the sleeve 22. The sealed bearing 215 can adopt a deep groove ball bearing or a multi-row roller bearing, which can effectively support the relative movement between the sleeve 22 and the stirring rod 21, improve the stability and reliability of the entire system, and prevent the mortar from entering the gap between the sleeve 22 and the stirring rod 21 during the stirring process, causing the sleeve 22 to be stuck on the stirring rod 21.

[0031] The implementation principle of the adaptive lubricating mortar transport mixing tank of the present application embodiment is as follows: when the rotating shaft 2 is driven to rotate, the stirring blade 23 is subjected to resistance from the lubricating mortar and transmitted to the pressure sensor 214. The pressure sensor 214 detects the resistance of the lubricating mortar on the stirring blade 23 in real time. When the resistance of the lubricating mortar on the stirring blade 23 is too large and the rotating shaft 2 cannot rotate normally, the servo cylinder 17 is driven by the electronic control system 15 to start, drive the stirring rod 21 to rise a certain distance, and then drive the rotating shaft 2 to rotate. If the stirring rod 21 still cannot stir normally after rising, the stirring rod 21 is driven to continue to rise until the rotating shaft 2 can rotate normally. During this process, the power unit keeps the rotating shaft 2 in a state of rotation and determines whether the rotating shaft 2 can rotate normally based on the pressure change value of the pressure sensor 214. After stirring for a certain period of time, the lifting control unit controls the stirring rod 21 to slowly descend while stirring, ultimately ensuring that all the sediment at the bottom of the tank body 1 is stirred up, thereby ensuring that the lubricating mortar has good uniformity during transportation and before use.

[0032] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
