Description

Technical Field

[0001] The utility model belongs to the technical field of PPR pipe connection and installation, and specifically relates to a PPR pipe connection and installation device. Background Art

[0002] At present, when connecting ppr pipes, the hot-melting method of a hot-melt fuser is often used. The operator contacts the ppr pipe and the pipe joint with the two heating dies of the hot-melt fuser for hot-melt heating, then slowly pulls out horizontally, and then quickly docks the ppr pipe and the pipe joint together to complete the connection of the ppr pipe. However, this connection method is mainly operated manually, and the temperature of the hot-melt fuser is high, which has certain safety hazards, and it is difficult to keep the level during the manual insertion process, which easily leads to low connection quality of the ppr pipe. In addition, there are also some automatic equipment that fixes and clamps the ppr pipe and the pipe joint to achieve automatic docking. However, due to the different outer diameters of the ppr pipe and the pipe joint, the axis height is inconsistent when clamping ppr pipes and pipe joints of different sizes, resulting in the inability to achieve connection, so that the equipment can only be applied to ppr pipes of fixed sizes. In addition, the existing clamping mechanism is often set to clamp the cylindrical shape, so the clamping of the pipe joint is often only applicable to the straight joint, and the right-angle joint or the three-way joint often cannot achieve good clamping due to the short clampable part, and the practicality is poor. Utility Model Content

[0003] The utility model aims to provide a ppr pipe connection and installation device to solve the problem that the existing ppr pipe connection and installation device can only be used for ppr pipes of one size and the clamping of different types of pipe joints is unreliable.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A PPR pipe connection and installation device comprises a base and a hot melt mechanism arranged on the base, wherein two clamping mechanisms are symmetrically and slidably connected on both sides of the hot melt mechanism on the base;

[0006] The clamping mechanism includes a slide seat and two clamp seats symmetrically slidably connected to the two slide seats.

[0011] Preferably, a gantry is fixedly mounted on the base, an electric push rod is fixedly passed through the middle of the gantry, and the top of the heating plate is fixedly connected to the telescopic end of the electric push rod.

[0012] Preferably, a turntable is rotatably connected to the clamp seat, and four arc grooves arranged in a circumferential array are opened on the turntable.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] (1) The utility model is provided with a clamping mechanism, in which four clamping blocks are provided with two mutually perpendicular arc-shaped clamping surfaces, and the four clamping blocks are arranged in a circumferential array, so that the clamping space directly formed by the four clamping blocks forms a cross-shaped structure, and then the clamping mechanism can clamp straight joints, right-angle joints and three-way joints stably and reliably through the relative sliding of two clamp seats on the slide seat.

[0018] (2) The utility model is provided with gears, racks and an electric push rod. When the ppr pipe and the pipe joint are connected, the engagement of the gears with the two racks enables the ppr pipe and the pipe joint clamped by the two clamping mechanisms to simultaneously approach the hot-melt mechanism in the middle and perform the hot-melt operation. Then, the gears are rotated in the opposite direction to pull the ppr pipe and the pipe joint out of the hot-melt mechanism. The hot-melt mechanism is lifted by the electric push rod to prevent obstruction of the connection between the ppr pipe and the pipe joint.

DETAILED DESCRIPTION

[0026] 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.

[0027] See also Figure 1-Figure 5 As shown, the utility model provides the following technical solutions:

[0028] A PPR pipe connection and installation device comprises a base 1 and a hot melt mechanism arranged on the base 1, and two clamping mechanisms are symmetrically and slidably connected on both sides of the hot melt mechanism on the base 1;

[0029] The clamping mechanism includes a slide 2 and two clamp seats 3 symmetrically slidably connected to the two slides 2. Four clamp blocks 4 are arranged in a circumferential array on each of the two clamp seats 3. Each clamp block 4 is provided with two arc-shaped clamping surfaces perpendicular to each other.

[0030] Based on the above disclosed structure, when performing the connection and installation operation of the PPR pipe:

[0031] First, place the ppr pipe and the pipe joint respectively in the cross-shaped clamping space formed between the eight clamping blocks 4 on the corresponding clamping mechanism, and slide two clamp seats 3 on the slide 2 so that the arc-shaped clamping surfaces of the corresponding eight clamping blocks 4 are in contact with the outer wall of the ppr pipe or the pipe joint, so as to achieve fixed clamping of the ppr pipe and the pipe joint, and then slide two slides 2 on the base 1 close to the hot melt mechanism so that the hot melt mechanism performs hot melt operation on the connecting ends of the ppr pipe and the pipe joint, and then slide the two slides 2 in the opposite direction so that the ppr pipe and the pipe joint are horizontally pulled out of the hot melt mechanism, and then the hot melt mechanism is moved out from the middle of the two clamping mechanisms, and then the two slides 2 are brought close to each other so that the hot melt end of the ppr pipe is slowly and horizontally inserted into the hot melt end of the pipe joint, and the connection of the ppr pipe and the pipe joint is completed after the hot melt part cools down.

[0032] In addition, the cross-shaped clamping space formed between the eight clamping blocks 4 in the clamping mechanism can achieve stable clamping of straight connectors, right-angle connectors and three-way connectors, making the device more practical and reliable.

[0033] Preferably, regarding the sliding of the two clamp seats 3, a double-headed screw 10 is rotatably connected to the slide seat 2, and the two clamp seats 3 are respectively screwed and connected to the two ends of the double-headed screw 10; a second motor 16 is fixedly installed on one side of the slide seat 2, and the output end of the second motor 16 is fixedly connected to one end of the double-headed screw 10. Based on this, after the ppr pipe or pipe joint is placed between the corresponding eight clamping blocks 4, the second motor 16 is started to drive the double-headed screw 10 to rotate, so that the two clamp seats 3 are close to each other, thereby driving the corresponding multiple clamping blocks 4 to move toward the middle, so as to achieve fixed clamping of the pair of ppr pipes or pipe joints, and the setting of the double-headed screw 10 enables the axis of the connection end of the ppr pipe and the pipe joint to be automatically aligned, which is convenient for subsequent hot melting and docking operations.

[0034] In order to realize the automatic connection between the PPR pipe and the pipe joint, the following structure is preferably provided:

[0035] A third motor 23 is fixedly mounted on the base 1, a gear 17 is fixedly mounted on the output shaft of the third motor 23, and racks 18 are fixedly mounted on both slides 2, and the two racks 18 are respectively meshed and connected to the two sides of the gear 17;

[0036] The hot melt mechanism includes a heating plate 9 and an inner heating die head 19 and an outer heating die head 20 disposed on both sides of the heating plate 9. The inner diameter of the inner heating die head 19 is equal to the outer diameter of the outer heating die head 20. A fixing bolt 24 that penetrates the heating plate 9 is screwed and connected between the inner heating die head 19 and the outer heating die head 20.

[0037] A gantry 8 is fixedly mounted on the base 1 , an electric push rod 7 is fixedly passed through the middle of the gantry 8 , and the top of the heating plate 9 is fixedly connected to the telescopic end of the electric push rod 7 .

[0038] As can be seen from the above, firstly, the corresponding internal heating die head 19 and external heating die head 20 are selected according to the size of the ppr pipe and the pipe joint, and then the internal heating die head 19 and the external heating die head 20 are screwed together by the fixing bolts 24 so that the internal heating die head 19 and the external heating die head 20 are respectively fixed on both sides of the heating plate 9, and then the heating plate 9 is energized to preheat the internal heating die head 19 and the external heating die head 20;

[0039] Then, after the ppr pipe and the pipe joint are clamped on the two clamping mechanisms respectively, the third motor 23 is started to drive the gear 17 to rotate, and the two racks 18 meshing on both sides of the gear 17 move relative to each other, thereby driving the two slides 2 to approach each other, so that the two clamping mechanisms respectively drive the ppr pipe and the pipe joint to approach the hot-melt mechanism, and the connecting end of the ppr pipe extends into the inner heating die 19 and the connecting end of the pipe joint is sleeved on the outer side of the outer heating die 20. After the hot-melt heating for a predetermined time, the third motor 23 is started to reversely drive the gear 17 to rotate, so that the two racks 18 drive the two slides 2 to move away from each other, so that the clamping mechanism respectively drives the ppr pipe and the pipe joint It is pulled out horizontally from the hot-melt mechanism, and then the electric push rod 7 is quickly started to retract the telescopic end, so that the heating frame 9 drives the inner heating die head 19 and the outer heating die head 20 to rise, thereby moving to the top of the two clamping mechanisms, and then the third motor 23 is started again to drive the gear 17 to rotate, so that the two racks 18 drive the two slides 2 to approach each other, so that the clamping mechanisms respectively drive the connecting ends of the ppr pipe and the pipe joint to approach each other, so that the hot-melt connecting end of the ppr pipe slowly and horizontally extends into the hot-melt connecting end of the pipe joint, and the automatic connection of the ppr pipe and the pipe joint is completed after the connecting end is cooled. The operation process is automatically controlled by the device, with high working efficiency and good connection quality.

[0040] In addition, in order to be able to clamp PPR pipes and pipe joints of different sizes, it is preferably provided with the following structure:

[0041] The fixture seat 3 is rotatably connected with a turntable 6, and the turntable 6 is provided with four arc-shaped grooves 21 arranged in a circumferential array. The four clamping blocks 4 are all fixedly mounted with slide bars 25, and the four slide bars 25 are slidably matched in the four arc-shaped grooves 21 in a one-to-one correspondence.

[0042] A guide plate 5 is fixedly mounted on the clamp seat 3 , and a guide groove of an X-shaped structure is provided on the guide plate 5 . Four clamping blocks 4 are slidably matched with four ends of the guide groove of the X-shaped structure respectively.

[0043] As can be seen from the above, by rotating the turntable 6, the four arc grooves 21 on the turntable 6 are respectively slidably matched with the four slide bars 25 on the four clamping blocks 4, and at the same time, the guide grooves of the X-shaped structure on the guide plate 5 enable the four clamping blocks 4 to slide only along the guide grooves of the guide plate 5, so that the four slide bars 25 drive the four clamping blocks 4 to approach the rotating axis of the turntable 6 at the same time, thereby reducing the distance between two adjacent clamping blocks 4, thereby reducing the clamping space between the two clamping blocks 4, which is convenient for clamping smaller-sized PPR pipes and pipe joints; conversely, rotating the turntable 6 in the opposite direction, so that the four slide bars 25 drive the four clamping blocks 4 to move away from the rotating axis of the turntable 6 at the same time, which is convenient for clamping larger-sized PPR pipes and pipe joints, thereby improving the practicality of the device.

[0044] In addition, the four clamping blocks 4 synchronously approach or move away from the axis of the turntable 6, so that the axes of the clamped PPR pipes and pipe joints are always horizontal with the axis of the turntable 6, so that the different outer diameters of the PPR pipes and pipe joints clamped by the two clamping mechanisms will not affect the horizontal docking of the PPR pipes and pipe joints, and no complicated leveling operation is required.

[0045] As mentioned above, regarding the rotation of the turntable 6, it is preferred to have the following structure:

[0046] A second handle 11 is fixedly connected to one side of the turntable 6, and a guide rod 12 is fixedly connected to one end of the second handle 11. A first handle 14 is rotatably connected to the base 1, and a connecting rod 13 is rotatably connected between the first handle 14 and the guide rod 12, and one end of the connecting rod 13 is slidably sleeved on the outer side of the guide rod 12;

[0047] A first motor 15 is fixedly mounted on one side of the base 1 , an output end of the first motor 15 is fixedly connected to a rotating shaft 22 that rotates and penetrates the slide 2 , and one end of the first handle 14 is fixedly connected to the rotating shaft 22 .

[0048] As can be seen from the above, the first motor 15 is started to drive the rotating shaft 22 to rotate, and the rotating shaft 22 drives the first rotating handle 14 to rotate. The first rotating handle 14, the connecting rod 13 and the second rotating handle 11 form a double rocker structure, so that one end of the first rotating handle 14 drives one end of the connecting rod 13 to move, so that the other end of the connecting rod 13 drives the second rotating handle 11 to rotate around the axis of the rotating disk 6 through the guide rod 12. The second rotating handle 11 is fixedly connected to the rotating disk 6, thereby driving the rotation of the rotating disk 6. In addition, the rotating shaft 22 rotates through the slide 2, and the two first rotating handles 14 in the same clamping mechanism are respectively fixed to the two ends of the rotating shaft 22, so as to facilitate the synchronous adjustment of the two rotating disks 6 in the same clamping mechanism, and the operation is simpler.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
