Description

Technical Field

[0002] After the glue injection of the lining hose is completed, the lining hose needs to be laid flat on the ground, and then the lining hose is rolled by a flattening rolling device. However, the moving stroke of the rolling device is limited. After each rolling distance, the rolled hose needs to be folded, and the unrolled hose needs to be moved to the moving stroke area of ​​the rolling device and rolled. However, if workers are required to fold it, they will need to enter the area where the equipment is running, which is dangerous and inconvenient. In addition, the workers cannot stare at the equipment while working, because it will take up more of their time. Therefore, the equipment needs to be folded automatically, but if the equipment moves at a fast speed when folding, it will cause the folded hose to be misplaced when stacking, resulting in an uneven final folding effect.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0032] Embodiment: The present invention provides a mobile device for flattening and rolling a trenchless UV-curable liner hose, such as Figure 1-3 As shown, it includes two rails 1 and a moving vehicle 2 that can move on the rails 1, a lifting mechanism 3 is fixedly arranged on the moving vehicle 2, a rotating and swinging mechanism 5 is fixedly arranged on the lifting seat of the lifting mechanism 3, the lifting mechanism 3 is used to push the rotating and swinging mechanism 5 upwards to move vertically, and two rolling arms 4 that can tilt and slide are arranged on the moving vehicle 2, the two rolling arms 4 are connected with the rotating and swinging mechanism 5 by transmission, and the rotating and swinging mechanism 5 is used to drive the two rolling arms 4 in the wrong direction away from or close to the hose, and the two rolling arms 4 can be driven to move in two directions by the moving vehicle 2 horizontally on the rails 1, and in the process of the rolling arms 4 moving, according to the moving direction of the moving vehicle 2, the rotating and swinging mechanism 5 can be rotated to make the rolling arm 4 on the side corresponding to the moving direction move downward, so that the rolling arm 4 squeezes the hose. It also includes a hook plate rotating mechanism 6, a speed switching mechanism 7, a connecting frame 10 and two hook plates 8. The connecting frame 10 is fixedly connected to the lifting seat of the lifting mechanism 3, the connecting frame 10 is located at the bottom of the mobile vehicle 2, the hook plate rotating mechanism 6 is fixedly installed at the bottom of the connecting frame 10, the two hook plates 8 are fixedly installed on the two rotating seats of the hook plate rotating mechanism 6, and the two hook plates 8 are respectively located on both sides of the hose. When the lifting seat of the lifting mechanism 3 moves downward to the final bottom position, the bottom of the hook plate 8 contacts the ground, and then the hook plate 8 is driven to rotate by the hook plate rotating mechanism 6. The hook plate 8 will rotate and be inserted into the bottom of the hose. The speed switching mechanism 7 is fixedly installed at the bottom of the mobile vehicle 2, and the speed switching mechanism 7 is used to switch the moving speed of the mobile vehicle 2. When the hook plate 8 is rotated and inserted to the bottom of the hose, the speed switching mechanism 7 will switch to reduce the moving speed of the mobile vehicle 2, and the lifting mechanism 3 will drive the lifting seat to move upward, so that the two hook plates 8 will simultaneously lift the hose upward, and then the mobile vehicle 2 will move, so that the hose hooks the hook plate 8 and moves horizontally, so that the hose is folded, and after the folding is completed, the hook plate rotating mechanism 6 drives the hook plate 8 to reset and rotate, and the hook plate 8 can be pulled out of the hose. The pulled out hook plate 8 will not contact the middle of the hose during the movement.

[0033] Among them, the slow moving speed can prevent the next layer of hoses from being offset when the hoses are stacked.

[0034] Since the moving load will increase when the hose is hooked up, a switching method similar to a gear box is required to avoid excessive increase in the load of the motor and to slow down the moving speed of the mobile vehicle 2. Figure 4 As shown, the speed switching mechanism 7 includes two unilateral switching mechanisms, a rotator 7b and an inner pulling mechanism 7h. Each unilateral switching mechanism includes an elastic buffer 7a, a rotating shaft 2 7c, two middle gears 7d, a small gear 7e and a large gear 7f. The mobile vehicle 2 is provided with a rotating shaft 1 2a for movement. When the rotating shaft 1 2a moves, the entire mobile vehicle 2 will move horizontally along the track 1. The rotating shaft 2 7c is rotatably installed at the bottom of the mobile vehicle 2. The rotator 7b is fixedly installed on the mobile vehicle 2. The rotator 7b is transmission-connected with the rotating shaft 2 7c. , the rotator 7b is used to drive the rotating shaft 2 7c to rotate, the elastic buffer 7a includes a sleeve 7a1, a spline groove is provided inside the sleeve 7a1, the area where the rotating shaft 2 7c contacts the sleeve 7a1 is a spline structure, one of the middle gears 7d is fixedly mounted on the sleeve 7a1, the other middle gear 7d is fixedly mounted on the rotating shaft 1 2a, the small gear 7e is fixedly mounted on the sleeve 7a1, the large gear 7f is fixedly mounted on the rotating shaft 1 2a, the inner pulling mechanism 7h is fixedly mounted on the moving vehicle 2, and the inner pulling mechanism 7h is used to pull the sleeve 7a1 to move horizontally;

[0035] Before the speed switching mechanism 7 switches the speed, the inner pulling mechanism 7h is not pulled, the two middle gears 7d are meshed with each other, and the small gear 7e is separated from the large gear 7f;

[0036] After the speed switching mechanism 7 switches the speed, the inner pulling mechanism 7h pulls the sleeve 7a1 to slide horizontally, the two middle gears 7d separate, and the small gear 7e meshes with the large gear 7f. After the sleeve 7a1 is pulled horizontally, the sleeve 7a1 will slide horizontally along the spline part of the rotating shaft 2 7c. First, the two middle gears 7d will separate. Then, after the small gear 7e contacts with the large gear 7f, if there is a conflict, the elastic buffer 7a can be used to buffer it to avoid a rigid collision. After the small gear 7e meshes with the large gear 7f, the small gear 7e can drive the large gear 7f to rotate, so that the moving vehicle 2 can move.

[0037] It should be noted that during the switching of the sleeve 7a1, the rotator 7b can keep working.

[0038] When the hook plate 8 is rotated and inserted into the bottom of the hose, the speed needs to be switched at the same time, and it is also necessary to ensure that the moving speed of the mobile vehicle 2 is slowed down after the hook plate 8 is rotated, otherwise a failure will occur, and since the connecting frame 10 is a cantilever beam, it itself cannot withstand a large supporting force, therefore, it is necessary to reduce the weight of the hook plate rotating mechanism 6, and at the same time, it is necessary to hook up the hose later, resulting in that the hook plate rotating mechanism 6 cannot be provided with a motor mechanism, for this reason, Figure 3 and Figure 5 As shown, the hook plate rotating mechanism 6 includes a guide slide 6d, two rotating gears 6a, two vertical shafts 6b and two racks 6c. The guide slide 6d is fixedly installed on the bottom of the mobile vehicle 2. The two vertical shafts 6b are both vertically slidably installed on the guide slide 6d. The two hook plates 8 are respectively fixedly installed on the bottom of the two vertical shafts 6b. The rotating gear 6a is fixedly installed on the outer edge of the vertical shaft 6b. The connecting frame 10 is fixedly connected to the top of the two vertical shafts 6b. The inner pulling mechanism 7h includes two slides 7h1 that can slide horizontally. When the inner pulling mechanism 7h is working, it will pull the two slides 7h1 inward. The sleeve 7a1 and the rack 6c are both fixedly installed on the slide 7h1. When the two slide plates 7h1 are pulled inward, the slide plates 7h1 will drive the rack 6c and the sleeve 7a1 to move inward at the same time. When the sleeve 7a1 moves, the speed switching mechanism 7 will switch the speed. When the rack 6c moves, the two hook plates 8 will be driven to rotate inward, so that the hook plates 8 can be screwed into the bottom of the hose, that is, it can ensure that after the hook plates 8 rotate, the moving speed of the mobile vehicle 2 is slowed down, reducing the occurrence of faults. In addition, the hook plate rotating mechanism 6 does not need to design a motor structure, which reduces the weight of the hook plate rotating mechanism 6.

[0039] After the hook plate 8 is screwed into the bottom of the hose, when the lifting mechanism 3 is pushed upward, the lifting mechanism 3 will drive the connecting frame 10 to move vertically upward, and the connecting frame 10 will pull the hook plate 8 upward to slide along the guide slide 6d through the vertical shaft 6b, that is, the hose can be hooked up. According to the different stacking heights, the height of the lifting mechanism 3 moving upward can be controlled to be different. During the upward movement of the hook plate 8, the rotating gear 6a will slide vertically along the rack 6c to ensure that the rotating gear 6a and the rack 6c can always be meshed. When the hook plate 8 needs to be pulled out later, it can be moved through the slide 7h1 so that the hook plate 8 can be rotated and pulled out.

[0040] When the rack 6c is pulled horizontally, the rack 6c will drive the rotating gear 6a to rotate, so that the rotating gear 6a can drive the hook plate 8 to rotate through the vertical shaft 6b. The edge of the hose is an arc structure, which enables the hook plate 8 to be rotated and inserted.

[0041] Since the connecting frame 10 is a cantilever beam structure, in order to prevent the connecting frame 10 from bending and to reduce the gravity when the connecting frame 10 brings the hose upward, for this purpose, Figure 3As shown, a plurality of weight-reducing mechanisms 9 are fixedly arranged on the top of the connecting frame 10, and each weight-reducing mechanism 9 includes a guide column 9a, a lifting spring 9b, a limiting circular plate 9c and a linear bearing 9d. The bottom of the guide column 9a is fixedly connected to the top of the connecting frame 10, the linear bearing 9d is fixedly installed on the moving vehicle 2, the guide column 9a is slidably connected to the linear bearing 9d, the limiting circular plate 9c is fixedly installed on the top of the guide column 9a, the lifting spring 9b is sleeved on the guide column 9a, one end of the lifting spring 9b is in conflict with the limiting circular plate 9c, and the other end of the lifting spring 9b is in conflict with the linear bearing 9d. The lifting spring 9b provides an upward elastic force to the guide column 9a, so that the guide column 9a can pull the connecting frame 10 upward, reducing the load on the connecting frame 10. And the end of the cantilever beam is supported to prevent it from bending.

[0042] like Figure 6 As shown, the elastic buffer 7a includes a resistance spring 7a2, a retaining ring 7a3, a push plate 7a4, a slide seat 7a5 and a slide rail 7a6, the push plate 7a4 is fixedly connected to the slide plate 7h1, the push plate 7a4 is slidably connected to the sleeve 7a1, the push plate 7a4 is provided with a rotating hole for the sleeve 7a1 to pass through, the retaining ring 7a3 is fixedly installed on the sleeve 7a1, the resistance spring 7a2 is sleeved on the sleeve 7a1, one end of the resistance spring 7a2 is in contact with the retaining ring 7a3, and the other end of the resistance spring 7a2 is in contact with the push plate 7a4. The push plate 7a4 is pushed horizontally by the slide plate 7h1, so that the resistance spring 7a2 can be driven to move horizontally, and if the pinion 7e is in contact, the resistance spring 7a2 is compressed, wherein the retaining ring 7a3 is used to limit and transmit the resistance spring 7a2. The slide rail 7a6 is fixedly mounted on the bottom of the moving vehicle 2, the slide seat 7a5 is fixedly connected to the top of the push plate 7a4, and the slide seat 7a5 is slidably connected to the slide rail 7a6. The slide seat 7a5 and the slide rail 7a6 guide and stabilize the movement of the push plate 7a4 to prevent the push plate 7a4 from rotating.

[0043] In order to be able to pull the slide plate 7h1 horizontally to perform horizontal movement, for this purpose, Figure 5 As shown, the inner pulling mechanism 7h includes an electric push rod 7h2, an articulated seat 7h4 and two articulated rods 7h3. The electric push rod 7h2 is fixedly installed at the bottom of the moving vehicle 2 through a connecting frame. The articulated seat 7h4 is fixedly installed at the bottom of the output end of the electric push rod 7h2. One end of the articulated rod 7h3 is articulated with the articulated seat 7h4, and the other end of the articulated rod 7h3 is articulated with the slide plate 7h1. By controlling the electric push rod 7h2 to move, the electric push rod 7h2 will pull the slide plate 7h1 through the articulated seat 7h4 and the articulated rod 7h3 to move horizontally, which can drive the speed switching mechanism 7 and the hook plate rotating mechanism 6 to work simultaneously.

[0044] In order to drive the connecting frame 10 and the rotating and swinging mechanism 5 to move upward or downward at the same time, for this purpose, Figure 7 As shown, the lifting mechanism 3 includes an electric push rod 2 3a, a lifting plate 3b and two guide pillars 2 3c. The guide pillars 2 3c can be installed on the moving vehicle 2 in a vertically sliding manner. The lifting plate 3b is fixedly installed on the top of the two guide pillars 2 3c. The electric push rod 2 3a is fixedly installed on the moving vehicle 2. The output end of the electric push rod 2 3a is fixedly connected to the lifting plate 3b. The connecting frame 10 is fixedly installed on the bottom of the two guide pillars 2 3c. By controlling the electric push rod 2 3a to work, the electric push rod 2 3a will drive the lifting plate 3b to move vertically, that is, it can lift the rotating swing mechanism 5 upward. And when the guide pillar 2 3c moves upward, it will drive the connecting frame 10 to move upward at the same time.

[0045] like Figure 1 and Figure 7 As shown, the mobile vehicle 2 includes a vehicle body 2b and a traveling gear 2c, a rotating shaft 2a is rotatably mounted on the vehicle body 2b, the traveling gear 2c is fixedly mounted on the rotating shaft 2a, a traveling rack 2d meshing with the traveling gear 2c is fixedly arranged on the ground surface, and the vehicle body 2b is slidably connected to the track 1. By rotating the rotating shaft 2a, the vehicle body 2b can travel on the track 1 through the meshing of the traveling gear 2c and the traveling rack 2d.

[0046] like Figure 7 As shown, the rotating and swinging mechanism 5 includes a rotating motor 5a and a rotating frame 5b. The rotating frame 5b is rotatably installed on the top of the lifting plate 3b through a rotating seat 1, and the rotating motor 5a is fixedly connected to the rotating seat 1. The output end of the rotating motor 5a is fixedly connected to the rotating shaft of the rotating frame 5b, so that the rotating motor 5a can drive the rotating frame 5b to rotate when it is working. Each rolling arm 4 includes a sliding column 5c, a connecting rod 5d, a guide column 3 5e and a pressure roller. The pressure roller is fixedly installed on the guide column 3 5e through the rotating seat 2. The guide column 3 5e is slidably connected to the moving vehicle 2. One end of the connecting rod 5d is fixedly connected to the rotating seat 2, and the sliding column 5c is fixedly installed on the other end of the connecting rod 5d. The rotating frame 5b is provided with a waist-shaped hole slidably connected to the sliding column 5c. When the rotating frame 5b rotates and swings, the sliding column 5c is pushed by the rotating frame 5b to move, so that the pressure roller can move along the length direction of the guide column 3 5e, and then the pressure roller can be controlled to approach or move away from the hose through the operation of the rotating motor 5a.

[0047] When in use, when the hook plate 8 is rotated and inserted to the bottom of the hose, the speed switching mechanism 7 will switch to reduce the moving speed of the mobile vehicle 2, and at the same time, the lifting mechanism 3 will drive the lifting seat to move upward, so that the two hook plates 8 will simultaneously lift the hose upward, and then move through the mobile vehicle 2, so that the hose hooks the hook plate 8 and moves horizontally, so that the hose is folded, and after the folding is completed, the hook plate rotating mechanism 6 drives the hook plate 8 to reset and rotate, and the hook plate 8 can be pulled out of the hose. The pulled out hook plate 8 will not contact the middle hose during the movement. Among them, the slow moving speed can prevent the next layer of hose from being driven to deviate when the hoses are stacked.
