Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example

[0030] The following reference Figure 1-Figure 7 As shown, further described in combination with a specific embodiment, this embodiment provides a hot melt connection device for drain pipe installation, referring to Figure 1 As shown, the invention comprises a base frame 1, a fixed pipe hoop 2 and a sliding pipe hoop 3. Both ends of the base frame 1 are welded with vertical support plates 11 in the vertical direction. Two guide rods 12 are welded between the two vertical support plates 11. The fixed pipe hoop 2 is fixedly installed between the two guide rods 12. The sliding pipe hoop 3 is slidably installed between the two guide rods 12 along the length direction of the guide rods 12. A driving assembly 4 for driving the sliding pipe hoop 3 to move is provided on the base frame 1. A mounting mechanism 5 for mounting the joint is provided between the fixed pipe hoop 2 and the sliding pipe hoop 3. The mounting mechanism 5 is slidably installed between the two guide rods 12 and can move in a direction close to the fixed pipe hoop 2 under the drive of the sliding pipe hoop 3. After the joint is firmly mounted by the mounting mechanism 5, one of the through ports of the joint and the end of the first pipe are heated to a molten state by a hot melter. The sliding pipe hoop 3 is driven to move in a direction close to the fixed pipe hoop 2 by the driving assembly 4. Under the drive of the sliding pipe hoop 3, the mounting mechanism 5 can drive the joint to move in a direction close to one of the pipes, thereby completing the connection between the first pipe and the first through port of the joint.

[0031] Reference Figure 2 As shown, the driving assembly 4 includes a driving motor 41, a lead screw 42 and a driving rod 43. A slide groove is provided on one side of the base frame 1 along its length direction. The lead screw 42 is rotatably connected in the slide groove and the length direction of the lead screw 42 is consistent with the length direction of the slide groove. The driving motor 41 is fixedly installed at one end of the base frame 1 and the output shaft of the driving motor 41 is coaxially connected with the lead screw 42. The driving rod 43 is an L-shaped rod. One end of the driving rod 43 is slidably connected in the slide groove and is threadedly connected with the lead screw 42. An auxiliary rod 44 is slidably installed on the other side of the base frame 1. The driving rod 43 and the end of the guide rod 12 away from the base frame 1 are both fixedly connected to the sliding pipe clamp 3. Starting the driving motor 41 to drive the lead screw 42 to rotate can drive the driving rod 43 to move along the length direction of the slide groove. The end of the driving rod 43 away from the slide groove can drive the sliding pipe clamp 3 to move in the direction close to or away from the fixed pipe clamp 2 along the length direction of the guide rod 12. During the movement, the auxiliary rod 44 plays a guiding role, further improving the stability of the sliding pipe clamp 3 during the sliding process.

[0032] Reference Figure 3 , Figure 4 As shown, the installation mechanism 5 includes a lower support 51, an upper support 52 and multiple groups of lifting components 53. Sleeves 511 are provided at both ends of the lower support 51. The two sleeves 511 are respectively slidably connected to the two guide rods 12. The upper support 52 is located directly above the lower support 51. The upper and lower support 52 and 51 have opposite sides each other provided with grooves 54 that can fit with the joint. The bottom ends of the multiple groups of lifting components 53 are respectively fixed to the four corners of the bottom of the lower support 51, and the top ends of the lifting components 53 are detachably connected to the upper support 52. The top end of the lifting component 53 is connected to the upper support 52. After the joint is installed on the lower support 51, starting the lifting component 53 can drive the upper support 52 to move in the direction close to the lower support 51 to achieve a pressing effect on the joint, thereby fixing the joint in the installation mechanism 5 and enabling the joint to move synchronously with the installation mechanism 5. It should be noted that, referring to Figure 5 As shown, the shape of the groove 54 in this embodiment is adapted to the shape of the four-way joint. The four-way joint has one more opening than the three-way joint, while the shapes of other parts are the same. Therefore, if the groove 54 is adapted to the shape of the four-way joint, the three-way joint can also be installed.

[0033] Reference Figure 4 As shown, an auxiliary ring 513 is provided at one end of the lower support 51 facing the sliding pipe hoop 3. The auxiliary ring 513 can be detachably mounted on the lower support 51 and can be clamped by the sliding pipe hoop 3. After the four-way joint is mounted on the mounting mechanism 5, the sliding pipe hoop 3 is clamped on the through-hole at the end of the four-way joint away from the fixed pipe hoop 2. Since the four-way joint and the mounting mechanism 5 are connected as one body, the sliding pipe hoop 3 can drive the mounting mechanism 5 to move synchronously during the movement. After the three-way joint is mounted on the mounting mechanism 5, since the end of the three-way joint away from the fixed pipe hoop 2 does not have a through-hole, the sliding pipe hoop 3 and the three-way joint cannot be directly fixed. At this time, the auxiliary ring 513 is mounted on the lower support 51, and then the sliding pipe hoop 3 is clamped on the auxiliary ring 513, that is, the relative position between the sliding pipe hoop 3 and the mounting mechanism 5 can be fixed, so that the sliding pipe hoop 3 can drive the three-way joint to move in the direction close to the fixed pipe hoop 2.

[0034] Specifically, a connecting seat 5131 is welded to one of the end faces of the auxiliary ring 513, and connecting bolts 5132 are passed through both sides of the connecting seat 5131. A threaded hole for inserting the connecting bolts 5132 is opened on the lower support 51. The connecting bolts 5132 are threadedly connected to the threaded holes at the corresponding positions, so that the auxiliary ring 513 can be fixed to the lower support 51. At this time, the auxiliary ring 513 is coaxially arranged with the sliding pipe clamp 3. The sliding pipe clamp 3 can be clamped on the auxiliary pipe to achieve the fixation of the position of the sliding pipe clamp 3 and the installation mechanism 5.

[0035] Reference Figure 4 , Figure 6 As shown, the lifting assembly 53 includes a driving electric cylinder 531, the cylinder of which is fixedly mounted on the lower support 51, a driving seat 532 is provided on the piston rod of the driving electric cylinder 531, a positioning piece 533 is provided on the driving seat 532, and a positioning groove 521 for inserting the positioning piece 533 is provided on the upper support 52. The positioning pieces 533 of multiple groups of lifting assemblies 53 are all inserted into the positioning grooves 521 at the corresponding positions of the upper support 52, so that the relative position between the lifting assembly 53 and the upper support 52 can be fixed. In the process of driving the driving seat 532 to move by the driving electric cylinder 531, the driving seat 532 can drive the upper support 52 to move synchronously, so that the upper support 52 moves toward the direction close to the lower support 51 and is pressed against the joint.

[0036] Reference Figure 5 As shown, auxiliary supports 6 are welded on opposite sides of the lower support 51, and auxiliary pipe hoops 61 are provided on the auxiliary supports 6; the auxiliary supports 6 are slidably connected to the lower support 51 through a slide bar 62, and a compression spring 63 is provided between the auxiliary support 6 and the lower support 51 for driving the auxiliary support 6 to move in a direction away from the lower support 51, and the compression spring 63 is sleeved on the outside of the slide bar 62, and a traction member 64 is provided in the lower support 51 for driving the auxiliary support 6 to move in a direction close to the lower support 51. When it is necessary to install the pipes on both sides to the through-ports on both sides of the joint, the two pipes are respectively installed on the auxiliary supports 6 on both sides, and the positions of the pipes are fixed by the auxiliary pipe hoops 61, and then the auxiliary support 6 can be driven to move in a direction close to the lower support 51 by the traction member 64, so that the pipes on both sides can be moved in a direction close to the joint, so as to achieve the connection between the pipes on both sides and the joint.

[0037] Reference Figure 7 As shown, the positioning member 533 includes a positioning block 5331, a mounting groove 5321 is provided on the driving seat 532, the positioning block 5331 is slidably set in the mounting groove 5321, and a pressure spring 5332 is connected between the positioning block 5331 and the bottom wall of the mounting groove 5321; the bottom surface of the positioning block 5331 facing one end of the positioning groove 521 is provided with an arc surface 5333. After placing the joint on the lower support 51, the upper support 52 is covered on the joint, and then the driving electric cylinder 531 is started to drive the driving seat 532 to move downward. Under the abutment action of the arc surface 5333 and the upper support 52, the positioning block 5331 is pressed into the installation groove 5321. When the positioning block 5331 is aligned with the positioning groove 521, the positioning block 5331 is inserted into the positioning groove 521 under the elastic force of the pressure spring 5332 to fix the relative position of the driving seat 532 and the upper support 52. At this time, the upper support 52 can be driven by the driving electric cylinder 531 to continue to move in the direction close to the lower support 51 and press against the joint, thereby realizing the positioning effect of the joint.

[0038] Reference Figure 5 , Figure 6 As shown, a pulling member 55 is provided on the upper support 52 and between two opposite positioning blocks 5331 for driving the positioning blocks 5331 to move out of the positioning groove 521. The pulling member 55 includes a pulling plate 551, and pulling belts 552 are provided at both ends of the pulling plate 551. One end of the pulling belt 552 away from the pulling plate 551 is fixedly connected to the groove wall of the positioning groove 521. After multiple pipes are hot-melt connected to the joint, the upper support 52 is lifted upward by the pulling plate 551. During the upward movement of the pulling plate 551, the pulling belt 552 will be driven to move upward first. The pulling belt 552 can abut against the arc surface 5333 and drive the positioning block 5331 to move out of the positioning groove 521. When the arc surface 5333 partially moves out of the positioning groove 521, the upper support 52 continues to move upward and can further drive the positioning block 5331 to move out of the positioning groove 521, and finally the positioning block 5331 is completely moved out of the positioning groove 521, so that the upper support 52 can be easily removed from the joint.

[0039] Reference Figure 5 , Figure 6 As shown, the traction member 64 includes a traction rope 641 and a connecting screw 642. A rope cavity 512 is provided in the lower support 51. The middle section of the traction rope 641 is located in the rope cavity 512. One end of the traction rope 641 is fixedly connected to the auxiliary support 6. The connecting screw 642 is fixedly connected to the end of the traction rope 641 away from the auxiliary support 6. A threaded hole matching the connecting screw 642 is provided on the driving seat 532. The connecting screw 642 is threadedly connected to the threaded hole on the driving seat 532. When the electric cylinder 531 drives the driving seat 532 to move upward, the driving seat 532 drives one end of the traction rope 641 to move upward through the connecting screw 642, so that the other end of the traction rope 641 pulls the auxiliary support 6, thereby driving the pipe installed on the auxiliary support 6 to move toward the direction close to the joint to facilitate hot melt connection.

[0040] Reference Figure 6 , Figure 7As shown, a support column 5311 is fixedly connected to the piston rod of the driving electric cylinder 531, and the driving seat 532 is rotatably mounted on the support column 5311. After all the pipes are hot-melt connected to the joints, a crane or other lifting mechanism is needed to lift the connected pipes and joints upward as a whole, so as to facilitate the removal of the hot-melt connection device as a whole. At this time, the driving seat 532 is rotated away from the joint to avoid obstruction to the lifting process of the joint. An alignment piece 5312 is provided on the support column 5311 and located at the upper part of the driving seat 532, and a socket is provided on the alignment piece 5312. An alignment rod 643 is provided at the top of the connecting screw 642. When the alignment rod 643 is inserted into the socket, the positioning member 533 is directly opposite to the positioning groove 521. When it is necessary to align the positioning member 533 with the positioning groove 521 to achieve the positioning effect on the upper support 52, the positioning member 533 is rotated to face the positioning groove 521. At this time, the connecting screw 642 is threadedly connected to the threaded hole on the driving seat 532 and the alignment rod 643 is extended out of the threaded hole. When the alignment rod 643 is inserted into the socket, the position between the driving seat 532 and the support column 5311 is fixed, so that the driving seat 532 will not rotate relative to the support column 5311, so as to improve the reliability of the positioning between the positioning member 533 and the upper support 52.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
