Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline repair, and in particular relates to an automatic pressing and straightening device for a PE hose used for repairing a water supply pipeline. Background Art

[0002] At present, the renovation of old urban water supply pipelines is generally based on trenching and pipe laying. However, for roads with large pedestrian and vehicle traffic and complex underground pipelines, trenchless repair technology can significantly reduce the impact of the construction process on road communications and surrounding residents, and the construction period is short, so water supply can be restored in the shortest time.

[0003] At present, the trenchless repair process of water supply pipelines usually requires the PE hose to be impregnated, that is, the adhesive is filled into the inside thereof so as to bond and solidify with the glass fiber to form the final water supply pipeline. However, the filled adhesive cannot be evenly distributed inside the PE hose. Currently, operators mostly hold a roller and slowly roll the adhesive from back to front to fill the inside of the PE hose. The operation time is long and the work efficiency is low. In addition, the quality of rolling and twisting mostly depends on the operator's feel. The uniformity of the adhesive distribution is difficult to ensure. The thickness of the PE hose after pressing is difficult to control, and it is difficult to meet the time requirements for on-site pipeline repair. Utility Model Content

[0004] The utility model provides an automatic pressing device for a PE hose for repairing a water supply pipeline, which solves the technical problems of long operation time and low efficiency of the existing manual pressing operation and poor control of the thickness of the PE hose after pressing.

[0005] The utility model can be realized through the following technical solutions:

[0006] An automatic pressing device for a PE hose for repairing a water supply pipeline comprises a moving roller and a fixed roller which are arranged in parallel and spaced apart from each other, both of which are arranged along the width direction of the PE hose, and the two ends of the moving roller are respectively connected to their corresponding driving support mechanisms, and the two driving support mechanisms move synchronously to drive the moving roller to move toward or away from the fixed roller, so as to adjust the gap between the moving roller and the fixed roller.

[0007] The fixed roller is also used as the driven roller of the first conveying mechanism. The first conveying mechanism and the second conveying mechanism are arranged on both sides of the fixed roller. The first conveying mechanism adopts an electrically driven synchronous belt conveying mechanism, and its conveying direction is obliquely upward, which is used to convey the PE hose filled with adhesive to the gap between the movable roller and the fixed roller, and to force the PE hose to pass through the gap to complete automatic pressing; the conveying direction of the second conveying mechanism is obliquely downward, which is used to receive and convey the pressed PE hose.

[0008] Furthermore, each of the driving support mechanisms includes a ball screw, the axial direction of which is perpendicular to the axial directions of the movable roller and the fixed roller, one end of which is connected to the output shaft of the motor, and the screw nut is connected to one end of the movable roller. The two motors rotate synchronously to drive the corresponding ball screws to rotate, thereby driving the movable roller to move up and down relative to the fixed roller, thereby adjusting the gap between the two.

[0009] Furthermore, one end of one of the ball screws is connected to the output shaft of the motor through a first commutator, and one end of the other ball screw is not connected to the motor but is connected to a second commutator. The first commutator is also connected to the second commutator through a connecting shaft, and the axial direction of the connecting shaft is parallel to the axial direction of the movable roller.

[0010] Furthermore, a guide rod is disposed on both sides of each ball screw, and the axial direction of each guide rod is parallel to the axial direction of the corresponding ball screw.

[0011] The ball screw and two guide rods on the same side of the movable roller are arranged inside the corresponding support shell, and their top and bottom ends are respectively connected to the support shell through their corresponding connecting blocks, and their rod parts are nested and connected to the same L-shaped connecting block. One side of the L-shaped connecting block is provided with openings corresponding to the positions of the ball screw and the two guide rods, and the openings corresponding to the guide rods are matched by bushings, and the openings corresponding to the ball screw are fixedly connected to the screw nut, and the other side of the L-shaped connecting block is fixedly connected to one end of the movable roller.

[0012] Furthermore, the second conveying mechanism includes a square frame, and a plurality of conveying rollers are arranged in parallel inside the square frame, and their two ends are respectively connected to the inner sides of the left and right sides of the square frame, and the outer sides of the left and right sides of the square frame are respectively connected to the corresponding supporting shell through their own corresponding connecting rod mechanisms, and the two connecting rod mechanisms are used to realize the folding or unfolding of the frame relative to the supporting shell.

[0013] Furthermore, a transition roller is arranged on the top edge of the square frame, and the axial direction of the transition roller is consistent with that of the fixed roller, and is used for transitionally transmitting the pressed PE hose to the transmission roller.

[0014] The beneficial technical effects of the utility model are as follows:

[0015] 1. With the help of the first transmission mechanism, the PE hose impregnated with the adhesive can pass through the gap between the moving roller and the fixed roller to implement the pressing operation without manual operation, saving time and labor costs, improving work efficiency, and meeting the on-site operation needs of water supply pipeline repair. The gap between the moving roller and the fixed roller can be adjusted by the driving support mechanism, so that the thickness of the PE hose after pressing can meet the repair needs of water supply pipelines of different specifications, expand the application scope of pipeline repair, and improve practicality.

[0016] 2. With the help of the connecting rod mechanism, the second conveying mechanism can be stored and unfolded to avoid occupying more use space, reduce the possibility of accidental injury, and improve safety and practicality. At the same time, the first conveying mechanism and the second conveying mechanism are cleverly arranged on both sides of the moving roller, one conveys obliquely upward and the other conveys obliquely downward, so that the PE hose impregnated with adhesive can be smoothly sent into the gap for compression, and then the compressed PE hose can be sent out. The overall structure is simple, easy to manufacture, and easy to promote and apply. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0023] like Figure 1-2 As shown, the utility model proposes an automatic pressing device for a PE hose for repairing a water supply pipeline, comprising a moving roller 1 and a fixed roller 2 which are arranged in parallel and spaced apart from each other, both of which are arranged along the width direction of the PE hose, and the two ends of the moving roller 1 are respectively connected to their respective corresponding driving support mechanisms 3, and the two driving support mechanisms 3 move synchronously to drive the moving roller 1 to move toward or away from the fixed roller 2, so as to adjust the gap size between the moving roller 1 and the fixed roller 2.

[0024] The fixed roller 2 is also used as a driven roller of the first conveying mechanism 4. The first conveying mechanism 4 and the second conveying mechanism 5 are arranged on both sides of the fixed roller 2. The first conveying mechanism 4 adopts an electrically driven conveyor belt conveying mechanism, and its conveying direction is obliquely upward, which is used to convey the PE hose filled with adhesive to the gap between the moving roller 1 and the fixed roller 2, and force the PE hose to pass through the gap to complete automatic pressing; the conveying direction of the second conveying mechanism 5 is obliquely downward, which is used to receive and convey the PE hose after pressing. In this way, the PE hose filled with adhesive is conveyed and forced to pass through the gap between the moving roller and the fixed roller by the first conveying mechanism, and automatic pressing is implemented without manual operation, which can greatly save manpower and improve work efficiency, and can make the adhesive evenly fill the PE hose, ensure the pressing thickness, and meet the actual needs of on-site operations. At the same time, the gap between the moving roller and the fixed roller can be adjusted by using the driving support mechanism, so that the thickness of the PE hose after pressing can meet the actual needs of water supply pipelines of different specifications, meet the performance requirements of repairing pipelines, and have strong operability and are easy to promote and apply.

[0025] The details are as follows:

[0026] like Figure 3-4 As shown, each driving support mechanism 3 includes a ball screw 31, the axial direction of which is perpendicular to the axial directions of the movable roller 1 and the fixed roller 2, one end of which is connected to the output shaft of the motor 32, and the screw nut is connected to one end of the movable roller 1. Depending on the control setting, the two motors 32 synchronously drive the corresponding ball screws 31 to rotate, so as to drive the movable roller 1 to move up and down relative to the fixed roller 2, so as to adjust the gap between the two and meet the thickness requirement of the PE hose after compression.

[0027] In order to save costs and ensure the smooth operation of the movable roller, we can use an electric motor to control the up and down movement of the movable roller, that is, one end of one ball screw 31 is connected to the output shaft of the motor 32 through the first commutator 33, and one end of the other ball screw 31 is not connected to the motor 32, but is connected to the second commutator 34, and the first commutator 33 is also connected to the second commutator 34 through the connecting shaft 35, and the axial direction of the connecting shaft 35 is parallel to the axial direction of the movable roller 1, so that the motor can drive one of the ball screws with the help of the first commutator, and at the same time transmit the motion to the connecting shaft and the second commutator to the other ball screw, so as to realize the synchronous movement of the two ball screws, and then the movable roller moves up and down relative to the fixed roller, so as to adjust the gap between the two.

[0028] In addition, a guide rod 36 is provided on both sides of each ball screw 31, and the axial direction of each guide rod 36 is parallel to the axial direction of the corresponding ball screw 31. The ball screw 31 and the two guide rods 36 on the same side of the moving roller 1 are arranged inside the corresponding support shell 38, and their top and bottom ends are respectively connected to the support shell 38 through their respective corresponding connecting blocks, and their rod parts are nested and connected with the same L-shaped connecting block 37. One side of the L-shaped connecting block 37 is provided with an opening corresponding to the position of the ball screw 31 and the two guide rods 36, and the openings corresponding to the guide rods 36 are By matching the shaft sleeve, that is, the shaft sleeve is put on the guide rod 36 and then assembled to the opening position to reduce the wear on the guide rod 36 and ensure smooth operation, the opening of the corresponding ball screw 31 is fixedly connected to the screw nut, and the other side of the L-shaped connecting block 37 is fixedly connected to one end of the movable roller 1. In this way, the support shell 38 is relied on to provide installation support and protection for the ball screw 31 and the two guide rods 36. At the same time, the L-shaped connecting block 37 is used to cleverly connect the movable roller 1 to the screw nut, and the guide rod and the ball screw can be connected together to provide auxiliary guiding effect for the movement of the ball screw.

[0029] The first conveying mechanism 4 includes an active roller and a driven roller connected by a conveyor belt, wherein the driven roller is replaced by the fixed roller mentioned above, and the two are shared. The active roller is driven by a motor to move, and the conveyor belt is driven by friction to realize the conveyance of the PE hose impregnated with adhesive.

[0030] Due to the active driving effect of the first conveying mechanism 4, the second conveying mechanism 5 can adopt a non-powered driving structure, and realize the conveying of the PE hose by means of rolling contact, that is, the second conveying mechanism 5 includes a square frame 51, and a plurality of conveying rollers 52 are arranged in parallel inside the square frame, and their two ends are respectively connected to the inner sides of the left and right sides of the square frame 51, so that the conveying rollers and the PE hose can be used to realize the conveying of the PE hose by rolling contact;

[0031] In addition, we connect the outer sides of the left and right sides of the frame 51 with the corresponding supporting shell 38 through their own corresponding connecting rod mechanisms 53. The two connecting rod mechanisms 53 are used to realize the folding or unfolding of the frame relative to the supporting shell to realize the storage of the second conveying mechanism 5. For example, each connecting rod mechanism 53 includes a first connecting rod and a second connecting rod. The two ends of the first connecting rod are respectively rotatably connected to the top of the frame and the corresponding position of the supporting shell, and the two ends of the second connecting rod are respectively rotatably connected to the middle of the frame and the corresponding position of the supporting shell. For the convenience of locking, we can design the second connecting rod into two rotatably connected parts, which are recorded as the third connecting rod. When the two third connecting rods are in the same straight line, the two are locked by using a pin shaft to realize the unfolding and locking of the second conveying mechanism.

[0032] In order to ensure that the compacted PE hose can be smoothly transferred to the second conveying mechanism 5, a transition roller 6 is arranged on the top edge of the frame 51. The axial direction of the transition roller 6 is consistent with the fixed roller 2, and a gap is left between the two. The PE hose coming out from between the movable roller 1 and the fixed roller 2 first reaches the transition roller, and under the action of its own weight, gradually reaches the conveying roller 52 of the second conveying mechanism 5, thereby gradually conveying the compacted PE hose to the required position.

[0033] Although specific embodiments of the present invention are described above, those skilled in the art should understand that these are merely examples and that various changes or modifications may be made to these embodiments without departing from the principles and essence of the present invention. Therefore, the scope of protection of the present invention is limited by the appended claims.
