[0027] 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.

[0028] like Figure 1 and Figure 2 As shown, a pipe locking device described in Example 1 of the utility model comprises a butt-joint pipe body and at least two clamping blocks 7 evenly distributed at the front end of the butt-joint pipe body, and a connecting plate 8 is hinged on the outside of the butt-joint pipe body. The number of connecting plates 8 corresponds to the clamping blocks 7, and the connecting plates 8 are all hinged on the outside of the butt-joint pipe body to form a swingable structure. One end of the connecting plate 8 is hinged to the clamping block 7; the butt-joint pipe body is provided with a driving mechanism connected to the other end of the connecting plate 8 for driving the connecting plate 8 to swing around the hinge point between the connecting plate 8 and the outside of the butt-joint pipe body, and the clamping blocks 7 at the end are driven to open and close through the swing of several connecting plates 8. In this embodiment, the butt-joint pipe body comprises a steel pipe 5 and a sleeve 1 coaxially arranged at the front end of the steel pipe 5, and the sleeve 1 is inserted into the discharge pipe. The end of the steel pipe 5 is used to connect the alumina storage bin unloading hose. The sleeve 1 can limit the discharge pipe, which facilitates the clamping block 7 to better clamp and fix the discharge pipe. Among them, at least two clamping blocks 7 are provided to form a clamping space. The driving mechanism drives one end of the connecting plate 8 to move so that the connecting plate 8 swings, thereby moving the clamping block 7 at the other end of the connecting plate 8 to form an opening and closing action, thereby releasing or clamping the discharge pipe.

[0029] In addition, if Figure 1 and Figure 2 As shown, the diameter of the sleeve 1 is larger than the steel pipe 5, and the sleeve 1 is connected to the steel pipe 5 through a ring plate. A sealing gasket 2 is provided on the side of the ring plate facing the sleeve 1 for sealing the butt discharge pipe. The outer side of the steel pipe 5 near the sleeve 1 is uniformly provided with intermediate ear plates 15 corresponding to the number of clamping blocks 7, and the middle part of the connecting plate 8 is hingedly connected to the outer side of the steel pipe 5 through the intermediate ear plates 15 through the pin shaft.

[0030] Embodiment 2 is different from Embodiment 1 in that the driving mechanism comprises a sliding member slidably arranged on the outside of the steel pipe 5 of the butt joint body and a driving member for driving the sliding member to slide axially along the butt joint body. The sliding member is provided with a first oblong hole 17, and the connecting plate 8 is hingedly and slidably connected to the sliding member by a pin passing through the first oblong hole 17.

[0031] Specifically, Figure 1 and Figure 2 As shown, the sliding member includes a guide tube 3 sleeved on the outside of the steel tube 5 of the butt joint body and guide tube ear plates 16 evenly distributed on the outside of the guide tube 3. Figure 3As shown, the first oblong hole 17 is arranged on the guide tube ear plate 16 along the radial direction of the guide tube 3. Through the radially arranged first oblong hole 17, not only the axial movement of the sliding member can be converted into the swing of the connecting plate 8, but also the jamming of the connecting plate 8 can be avoided. In this embodiment, the driving member is a small cylinder 9. The outer diameter of the above-mentioned ring plate is larger than the sleeve 1, so that the ring plate radially extends out of the outside of the steel pipe 5 and the sleeve 1. An angle plate 13 is fixed on the guide tube 3. The telescopic direction of the small cylinder 9 is arranged along the axial direction of the guide tube 3, and one end of the small cylinder 9 is fixed to the ring plate, and the other end is connected to the angle plate 13 to push the guide tube 3 to slide axially.

[0032] Embodiment 3 is different from Embodiment 2 in that Figure 1 and Figure 2 As shown, the outer side of the butt-jointed tube body is uniformly provided with axial guide shafts 10, and the outer side of the guide cylinder 3 is provided with an ear seat that slides with the guide shaft 10, and the guide shaft 10 is slidably penetrated on the ear seat, so as to limit the sliding of the guide cylinder 3 in the axial direction more stably. In this embodiment, a second ring plate parallel to the ring plate is provided on the outer side of the steel pipe 5, and the two ends of the guide shaft 10 are respectively connected and fixed to the ring plate and the second ring plate.

[0033] Embodiment 4 is different from Embodiment 1 in that Figure 4 As shown, the clamp block 7 is provided with a second oblong hole 18. In this embodiment, a clamp block ear plate 14 is provided on the outer side of the clamp block 7, and the second oblong hole 18 is provided on the clamp block ear plate 14. The connecting plate 8 is hingedly and slidably connected to the clamp block 7 by passing a pin through the second oblong hole 18.

[0034] In addition, a slide rail 11 is provided at the front end of the butt joint body. Figure 2 and Figure 4 As shown, in this embodiment, a radial slide rail 11 is provided on the front side of the ring plate, and a slider 12 slidably matched with the slide rail 11 is provided on the rear side of the clamping block 7, so as to realize radial movement of the clamping block 7.

[0035] Embodiment 5 is different from Embodiment 4 in that Figure 1 and Figure 4 As shown, the sleeve 1 is evenly provided with slots 19 corresponding to the clamping blocks 7 for the clamping blocks 7 to penetrate into the slots 19 to clamp the discharge pipe.

[0036] Embodiment 6 is different from Embodiment 1 in that Figure 1 and Figure 2 As shown, it also includes a support 6 for fixing the butt joint body, so as to facilitate the installation of the device at the corresponding material connection position. The steel pipe 5 of the butt joint body is detachably connected to the support 6.

[0037] Furthermore, the support 6 is detachably connected with a clamp 4 for clamping the butt joint body. Specifically, the support 6 is provided with a plurality of vertical plates with U-shaped openings, and the steel pipe 5 can be placed in the U-shaped openings. The clamp 4 is provided with a plurality of blocks, and the plurality of blocks can be enclosed on the outside of the steel pipe 5. The blocks of the clamp 4 are connected to the vertical plates by bolts to fix the steel pipe 5.

[0038] The pipe locking device of the utility model is mainly used for the docking and locking of the discharge pipe of the tank truck, and assists the tank truck in feeding. After the tank truck arrives at the designated area, the locking device starts to work after contacting the discharge pipe. The specific process is as follows:

[0039] The discharge pipe enters the sleeve 1 and rests on the sealing gasket 2 in the sleeve 1 to ensure sealing. The two small cylinders 9 start to extend backward at the same time, driving the guide cylinder 3 to slide backward on the guide shaft 10 through the angle plate 13. The pin of the connecting plate 8 moves from the inner end of the first oblong hole 17 to the outer end. The connecting plate 8 rotates around the pin on the middle ear plate 15, and the front pin moves from the front end of the second oblong hole 18 to the rear end. Therefore, the two clamps 7 move inward along the slide rail 11 through the slider 12 and enter the front end slot of the sleeve 1, tightly clamping the discharge pipe to achieve the clamping purpose. After the feeding is completed, the small cylinder 9 returns to its original position, the two clamps 7 withdraw from the slot, release the discharge pipe, and the tank truck leaves to complete the feeding work. The whole process is simple and fast, easy to operate, and greatly improves production efficiency.
