Description
Technical Field
[0001] The utility model relates to the technical field of cement tank trucks, in particular to a cement discharge pipe quick-connect structure of a cement tank truck. Background Art
[0002] Cement tank trucks, also known as bulk cement trucks, powder tank trucks, tank trucks, and powder and granular material transport trucks, are composed of a special vehicle chassis, a bulk cement truck tank body, an air piping system, and an automatic unloading device.
[0003] The external connecting pipe of the cement tank truck is used to pump the cement in the tank to the construction site through a pump. Before pumping the cement, the pipe connecting the tank body needs to be connected to the pipe of the external equipment. The existing connection method generally uses a flange or quick-connect buckle connection method.
[0004] Since pipeline connection is performed manually, the pipeline itself is relatively heavy, the flange connection speed is slow, and the quick connector is heavy and inconvenient for the workers to perform the connection operation.
[0005] Therefore, it is necessary to provide a cement discharge pipe quick-connect structure for a cement tank truck to solve the above technical problems. Utility Model Content
[0006] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a cement discharge pipe quick-connect structure of a cement tank truck, which can facilitate workers to connect the pipe.
[0007] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:
[0008] The quick-connect structure of the cement discharge pipe of a cement tanker includes: a discharge pipe, one end of which is installed on the cement tanker, and a connecting pipe is installed on the other end of the discharge pipe. The outer wall of the connecting pipe is provided with a second limiting ring, and the inner wall of the connecting pipe is provided with a sealing ring. The caliber of the second limiting ring is consistent with that of the sealing ring. The other end of the connecting pipe is threadedly installed on the inner wall of the output pipe, and the outer wall of the connecting pipe is provided with a rotating shaft, and the rotating shaft is provided with a handle.
[0009] Preferably, an enlarged opening is provided at one end of the output pipe close to the connecting pipe, and the inner diameter of the enlarged opening is the same as the outer diameter of the discharge pipe.
[0010] Preferably, a first limiting ring is fixedly provided on the inner wall of the discharge pipe, and the distance between the first limiting ring and the end of the discharge pipe is the same as the distance between the second limiting ring and the sealing ring.
[0011] Preferably, a rubber pad is provided on one side of each of the first limiting ring and the second limiting ring.
[0012] Preferably, the handle is rod-shaped, and blocks are provided at both ends of the handle, and the blocks are thicker than the handle.
[0013] Preferably, the handle is detachably connected to the stopper.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] (1) The utility model realizes the effect of quick connection between the discharge pipe and the output pipe by setting a connecting pipe. The handle can reduce the force required by the staff to rotate the connecting pipe, thereby reducing the labor intensity of the staff and facilitating operation;
[0016] (2) The connecting pipe and the discharge pipe of the utility model are heavy, which makes it inconvenient for workers to connect them by hand, and the precision is difficult to control. By providing an enlarged opening, the connecting pipe can be inserted more easily, reducing the difficulty of aligning and connecting the connecting pipe and the discharge pipe;
[0017] (3) The utility model can improve the safety of the connecting pipe by providing the first limiting ring, limit the further movement of the connecting pipe, and prevent the connecting pipe from being over-tightened, which may cause excessive pressure between the second limiting ring and the sealing ring and lead to damage.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.
[0023] First embodiment:
[0024] like Figure 1-3As shown in the figure, the cement discharge pipe quick connection structure of the cement tanker provided by the present invention includes: a discharge pipe 101, one end of which is installed on the cement tanker, and the cement is discharged from the tank body of the tanker through the discharge pipe 101 when pumping, and the flow direction is as follows: Figure 1 As shown by the large gray arrow, a connecting pipe 102 is installed at the other end of the discharge pipe 101, and the connecting pipe 102 connects the discharge pipe 101 and the output pipe 103. The other end of the output pipe 103 is connected to an external device such as a pump. A second limiting ring 106 is provided on the outer wall of the connecting pipe 102, and a sealing ring 107 is provided on the inner end of the connecting pipe 102. The shape of the ring is as shown in FIG. Figure 2 As shown in , the second limiting ring 106 is consistent with the caliber of the sealing ring 107. The other end of the connecting pipe 102 is threadedly installed on the inner wall of the output pipe 103. The outer wall of the connecting pipe 102 is provided with a rotating shaft 108, and the rotating shaft 108 is provided with a handle 109. When in use, first align the end of the connecting pipe 102 with the discharge pipe 101 and use the handle 109 to rotate the connecting pipe 102. The specific operation is as follows Figure 3 As shown, rotate the handle 109 so that it is perpendicular to the axis of the connecting tube 102, then pull one end of the handle 109 close to the rotating shaft 108, and the other end away from the rotating shaft 108, push the end of the handle 109 away from the rotating shaft 108, and this part forms a lever structure. The end of the handle 109 close to the rotating shaft 108 pushes the connecting tube 102 to rotate. At the same time, under the action of the surface threads of the two, the connecting tube 102 is gradually pushed into the inside of the discharge tube 101, and stops rotating when the second limiting ring 106 contacts the surface of the sealing ring 107. At this time, the connecting tube 102 connects the discharge tube 101 with the output tube 103.
[0025] The connection tube 102 is provided to achieve the effect of quick connection between the discharge tube 101 and the output tube 103 . The handle 109 can reduce the force required by the staff to rotate the connection tube 102 , thereby reducing the labor intensity of the staff and facilitating operation.
[0026] Second embodiment:
[0027] like Figure 2 As shown, an enlarged port 105 is provided at one end of the output pipe 103 close to the connecting pipe 102. The enlarged port 105 is annular and fixed at the opening of the output pipe 103. The inner diameter of the enlarged port 105 is the same as the outer diameter of the discharge pipe 101, that is, the outer diameter is larger.
[0028] The connecting tube 102 and the discharge tube 101 themselves have a certain weight, and it is inconvenient for the staff to connect the two by holding them, and the accuracy is difficult to control. By setting the enlarged opening 105, the connecting tube 102 can be easily inserted, reducing the difficulty of aligning and connecting the connecting tube 102 and the discharge tube 101.
[0029] Third embodiment:
[0030] like Figure 2 As shown, a first limiting ring 104 is fixedly provided on the inner wall of the discharge pipe 101. The distance between the first limiting ring 104 and the end of the discharge pipe 101 is the same as the distance between the second limiting ring 106 and the sealing ring 107. When the connecting pipe 102 rotates and moves gradually to the left, the second limiting ring 106 contacts the sealing ring 107 while the other end of the connecting pipe 102 contacts the first limiting ring 104.
[0031] The first limiting ring 104 can improve the safety of the connecting tube 102, limit the further movement of the connecting tube 102, and prevent the connecting tube 102 from being over-tightened, which may cause excessive pressure between the second limiting ring 106 and the sealing ring 107 and cause damage.
[0032] Fourth embodiment:
[0033] Rubber pads are provided on one side of the first limiting ring 104 and the second limiting ring 106 respectively. The rubber pads can increase the connection sealing and reduce the contact wear between the ports of the first limiting ring 104 and the second limiting ring 106 and the connecting pipe 102.
[0034] Fifth embodiment:
[0035] like Figure 3 The handle 109 is rod-shaped, and blocks 110 are provided at both ends of the handle 109. The blocks 110 are thicker than the handle 109, which can prevent the handle 109 from slipping off the rotating shaft 108. The handle 109 and the block 110 are threadedly connected, which facilitates the disassembly and installation of the handle 109 and the block 110 during production or maintenance and replacement.
[0036] Working principle: When in use, first align the end of the connecting pipe 102 with the discharge pipe 101 and use the handle 109 to rotate the connecting pipe 102. The specific operation is as follows: Figure 3 As shown, rotate the handle 109 so that it is perpendicular to the axis of the connecting tube 102, then pull one end of the handle 109 close to the rotating shaft 108, and the other end away from the rotating shaft 108, push the end of the handle 109 away from the rotating shaft 108, and this part forms a lever structure. The end of the handle 109 close to the rotating shaft 108 pushes the connecting tube 102 to rotate. At the same time, under the action of the surface threads of the two, the connecting tube 102 is gradually pushed into the inside of the discharge tube 101, and stops rotating when the second limiting ring 106 contacts the surface of the sealing ring 107. At this time, the connecting tube 102 connects the discharge tube 101 with the output tube 103.
[0037] The above embodiment is only one of the preferred implementation methods of the present invention and should not be used to limit the scope of protection of the present invention. Any changes or modifications that have no substantive meaning made to the main design concept and spirit of the present invention, as long as the technical problems they solve are still consistent with the present invention, should be included in the scope of protection of the present invention.
