[0028] like Figure 1 and Figure 2As shown, the cement pole capping machine includes an outer cylinder 1, an inner liner 3 and an extrusion mechanism. The outer cylinder 1 is mounted on the cement pole, and the outer cylinder 1 and the cement pole are locked by a fastening device installed on the outer cylinder 1. The inner liner 3 is installed in the outer cylinder 1, and the outer cylinder 1 is equipped with an extrusion mechanism. The extrusion mechanism is connected with the inner liner 3, and the extrusion mechanism pushes the inner liner 3 to move relative to the outer cylinder 1. When working, cement mortar is placed on the inner liner 3, and then the outer cylinder 1 is mounted on the cement pole, and then the fastening device is locked. The extrusion mechanism works to push the inner liner 3 to move along the outer cylinder 1. When the cement mortar contacts the cement pole, the cement mortar is squeezed. With the movement of the inner liner 3, the capping of the cement pole is finally completed. Since the cement pole is heavy, for ease of operation, the cement poles are placed horizontally or tend to be placed horizontally.

[0029] In this embodiment, if Figure 3 and Figure 4 As shown, the inner liner 3 includes a sealing cap 39, a bearing sleeve 35, a bearing 37 and a bearing cover 36. The sealing cap 39 is provided with a bearing sleeve 35, and a bearing 37 is installed in the bearing sleeve 35. A bearing cover 36 is also installed on the top of the bearing sleeve 35 to prevent the bearing 37 from withdrawing from the bearing sleeve 35. The extrusion mechanism includes a screw drive shaft 4, a top cover 2 is installed on the top of the outer cylinder 1, and a nut b21 is provided on the top cover 2. The screw drive shaft 4 is threadedly matched with the nut b21, and the end of the screw drive shaft 4 is connected to the bearing sleeve 35. When the screw drive shaft 4 is rotated, the screw drive shaft 4 rotates in the nut b21, thereby realizing the advancement and retreat of the screw drive shaft 4, that is, when the screw drive shaft 4 rotates forward, the inner liner 3 advances relative to the outer cylinder 1, and when the screw drive shaft 4 is reversed, the inner liner 3 retreats relative to the outer cylinder 1. In this embodiment, as shown in FIG. Figure 5 As shown, the screw drive shaft 4 includes a threaded section 41 and a polished rod section 42, a limiting step 44 is formed between the polished rod section 42 and the threaded section 41, the threaded section 41 is threadedly matched with the nut b21, the polished rod section 42 is connected to the bearing sleeve 35, a slot 43 is provided on the polished rod section 42, a retaining spring 45 is installed on the slot 43, the bearing 37 is limited between the retaining spring 45 and the limiting step 44, preferably, one end of the bearing 37 contacts with the limiting step 44, and the other end of the bearing 37 contacts with the retaining spring 45, so that when the screw drive shaft 4 rotates forward, the limiting step 44 abuts against the bearing 37, thereby transmitting power to the inner liner 3, so that the inner liner 3 moves forward relative to the outer cylinder 1, and when the screw drive shaft 4 reverses, the retaining spring 45 abuts against the bearing 37, thereby pulling the inner liner 3 backward relative to the outer cylinder 1, and the retaining spring 45 can also prevent the polished rod section 42 of the screw drive shaft 4 from exiting the bearing 37, thereby ensuring the stability of the connection between the screw drive shaft 4 and the bearing 37.

[0030] In this embodiment, a slider 11 is installed on the inner wall of the outer tube 1, and a guide bracket 33 is radially installed on the top plate 34 of the inner liner 3. A guide groove 38 is provided on the guide bracket 33. The slider 11 slides in the guide groove 38. The sliding fit between the slider 11 and the guide groove 38 ensures the straightness of the movement of the inner liner 3, thereby ensuring the coaxiality of the sealing cap and the cement pole.

[0031] In this embodiment, the cap cover 39 includes a lower skirt 31, a middle skirt 32 and a top plate 34. The lower skirt 31 is connected to the middle skirt 32, and the middle skirt 32 is connected to the top plate 34. The lower skirt 31, the middle skirt 32 and the top plate 34 form a concave receiving groove. When in use, cement mortar is placed in the receiving groove. When the cement mortar contacts the cement pole, the cement mortar is deformed. As the cement mortar is continuously squeezed, the cement mortar moves along the gap of the receiving groove, and finally a cap matching the shape of the receiving groove is formed.

[0032] In this embodiment, the fastening device includes a nut a13 and a fastening screw 14. A nut a13 is installed on the outer wall of the bottom of the outer cylinder 1, and a fastening screw 14 is installed on the nut a13. The fastening screw 14 passes through the side wall of the outer cylinder 1 along the radial direction of the outer cylinder 1. After the outer cylinder 1 is put on the cement pole, the fastening screw 14 is locked, thereby achieving a stable installation of the outer cylinder 1 and the cement pole. Furthermore, a gasket 12 is also provided on the inner wall of the bottom of the outer cylinder 1. The connecting line of the gasket 12 and the fastening screw 14 passes through the central axis of the outer cylinder 1. Preferably, the thickness of the gasket 12 is the difference between the radius of the inner cavity of the outer cylinder 1 and the radius of the cement pole, and the gasket 12 has an arc surface matching the cement pole. Therefore, when the fastening screw 14 is locked, the coaxiality of the outer cylinder 1 and the cement pole can be guaranteed. Therefore, when the cement pole is capped, the cap can maintain good coaxiality with the cement pole.

[0033] In this embodiment, an observation window a15 and an observation window b16 are installed on the side wall of the outer cylinder 1, and the observation window b16 is located above the observation window a15. Preferably, there are two observation windows a15 and b16, and the two observation windows a15 are symmetrically arranged relative to the screw drive shaft 4, and the two observation windows b16 are symmetrically arranged relative to the screw drive shaft 4. The operator can intuitively observe the movement of the inner liner 3 through the observation windows a15 and b16, thereby facilitating the sealing of the cement pole cap. In addition, the observation windows a15 and b16 can also reduce the weight of the outer cylinder 1, saving production costs. , and it also reduces the difficulty of operation. More importantly, when the cement pole capping is completed, cement mortar remains on the inner wall of the inner liner 3 and the outer tube 1, and the cement mortar needs to be flushed in time. In order to improve the flushing efficiency and prevent the cement mortar from entering the bearing 37, the cement pole capping machine needs to be placed horizontally, and then flushed with water from an observation window a15 and an observation window b16. The residue liquid after flushing flows out from another observation window a15 and an observation window b16, thereby preventing the residue liquid from entering the bearing 37 and affecting the use effect of the bearing 37, while ensuring the flushing efficiency.

[0034] In this embodiment, a handle 17 is also installed on the outer wall of the outer tube 1. The handle 17 is installed on the outer wall of the outer tube 1 by welding. The handle 17 facilitates the holding of the cement pole capping machine and also facilitates the installation of the cement pole capping machine.

[0035] In this embodiment, the top cover 2 is connected to the outer cylinder 1 via a locking assembly 22. Furthermore, a flange is provided on the top of the outer cylinder 1, and a through hole connected to the flange hole is provided on the edge of the top cover 2. The locking assembly 22 is a universal bolt assembly. The bolts are installed in the flange holes and then the bolts are locked. Of course, in other embodiments, a connecting block may be provided on the top edge of the outer cylinder 1, and a through hole may be provided on the connecting block. Similarly, a connecting block may be provided on the edge of the top cover 2, and a through hole may be provided on the connecting block, and then the bolt assembly may be used to lock the connection.
