Description

Technical Field

[0001] The present invention relates to the technical field of cutting target objects, and in particular to a multifunctional cutting pulley steering device. Background Art

[0002] In tunnel construction, the cast-in-place reinforced concrete structure at the tunnel interface is generally externally reinforced. After the formwork is removed, the target cutting material extends a certain distance beyond the side wall. However, due to the existing tunnel structure, the target cutting material that extends beyond the side wall needs to be cut away. This cutting operation is performed using a diamond rope cutter. Due to the narrow working surface of the tunnel interface, the adaptability and accuracy of the cutting device are very demanding. Therefore, it is necessary to develop a convenient and efficient cutting device. Summary of the Invention

[0003] The purpose of the present invention is to provide a multifunctional cutting pulley steering device, which can enhance the adaptability of the entire cutting device to the environment, ensure the correct entry angle of the diamond rope into the wheel, reduce the wear of the diamond rope, improve the flatness of the cutting surface of the target object, reduce the failure rate of the device and improve work efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solutions: a multifunctional cutting pulley steering device, comprising a fixed support mounted on a wall, a horizontal beam mounted on the fixed support, an end of the horizontal beam away from the fixed support being connected to a vertical beam via a fixed connecting block, the horizontal beam and the vertical beam being perpendicular to each other, and a first pulley block and a second pulley block being mounted on both upper and lower ends of the vertical beam;

[0005] A wire saw machine, wherein the wire saw machine is used to drive the driving wheel to rotate;

[0006] A diamond rope is used to cut the target object. The diamond rope passes through the first pulley group at the upper end of the vertical beam, the second pulley group, the driving wheel, the second pulley group at the lower end of the vertical beam, the first pulley group, and the target object in sequence, and is closed into a loop;

[0007] The first pulley group at the upper end of the vertical beam is located directly above the first pulley group at the lower end of the vertical beam, and the diamond rope between the second pulley group at the upper end of the vertical beam and the driving wheel and the diamond rope between the second pulley group at the lower end of the vertical beam and the driving wheel are located on the same plane.

[0008] It can be seen from the above technical solution that the diamond rope is turned by the mutual cooperation of the first pulley group and the second pulley group, so that the rope saw machine can be placed in a position that is not in the same plane as the cutting surface of the target cutting object, thereby improving the applicability of the cutting device in the case of a narrow working surface; wherein the first pulley group located at the upper end of the vertical beam is located directly above the first pulley group at the lower end of the vertical beam, ensuring that the diamond rope for cutting the target cutting object is in the same plane as the ideal cutting surface, so that the cutting surface remains flat; the diamond rope between the second pulley at the upper end of the vertical beam and the driving wheel and the diamond rope between the second pulley at the lower end of the vertical beam and the driving wheel are located on the same plane, so that the diamond rope is not easy to separate from the driving wheel, thereby improving the stability of the cutting process.

[0009] A further solution is that fixing sleeves are provided at both ends of the vertical beam, the fixing sleeves are fastened to the vertical beam by bolts, and the first pulley group and the second pulley group are installed on both sides of the fixing sleeves.

[0010] It can be seen from the above technical solution that the fixing sleeve can be locked on the vertical beam by tightening the fixing sleeve with bolts. When the bolts are loosened, the fixing sleeve can be rotated with the central axis of the vertical beam and the position of the fixing sleeve can be adjusted up and down, so that the center line of the first pulley is parallel to the central axis of the target cutting object, which is suitable for cutting target cutting objects that are tilted left and right relative to the wall. At the same time, the distance between the two first pulleys is changed to adapt to target cutting objects with different diameters, further improving the applicability of the cutting device.

[0011] A further solution is to mount a first indicator needle on the fixing sleeve, and to provide first scale lines around the vertical beam near the fixing sleeve. By measuring the angle between the center axis of the target object and the wall, the first indicator needle and the first scale lines can be used to quickly adjust the center line of the first pulley to the center axis of the target object.

[0012] A further solution is that a bearing is installed in the fixed connecting block and a groove is opened, the beam is interference fit with the inner ring of the bearing and a turntable is provided on the outer surface of the beam, the turntable is set in the groove, and a number of slots are equidistantly spaced around the turntable, a limit plate is rotatably connected to the side wall of the groove, a block is provided on the side of the limit plate close to the groove, the block is adapted to the slot, a baffle is rotatably connected to the outer surface of the beam, the baffle is used to support the bottom end of the limit plate, and a knob is installed on the baffle.

[0013] It can be seen from the above technical solution that the bearing limits the forward and backward movement of the fixed connection block relative to the central axis of the beam. When the restriction of the baffle on the limit plate is released, the fixed connection block can be rotated relative to the beam, driving the limit plate to rotate outward, thereby driving the card block to disengage from the slot, adjusting the center line of the first pulley to be parallel to the central axis of the target cutting object, and adapting to cutting the target cutting object that is tilted up and down relative to the wall; when the rotation angle of the fixed connection block relative to the beam is adjusted, the limit plate is driven to rotate inward, thereby driving the card block to embed into the slot, and at the same time rotating the baffle so that the baffle presses against the limit plate, thereby locking the position of the fixed connection block relative to the beam.

[0014] A further solution is that a second indicator needle is installed on the fixed connection block, and a second scale line is circumferentially provided at a position relative to the crossbeam.

[0015] A further solution is that the first pulley group includes a first pulley and a first positioning frame, the first pulley is rotatably connected to the first positioning frame via a pulley shaft, and the second pulley group includes a second pulley and a second positioning frame, the second pulley is rotatably connected to the second positioning frame via a pulley shaft.

[0016] A further solution is that the first pulley and the second pulley are provided with V-shaped wire grooves which can limit the displacement of the diamond rope and prevent the diamond rope from being separated from the first pulley or the second pulley.

[0017] A further solution is that the wire saw machine is mounted on a trolley, and the trolley is used to drive the wire saw machine to move back and forth, thereby tensioning the diamond wire rope.

[0018] Compared with the prior art, the beneficial effects of the present invention are: the multifunctional cutting pulley steering device proposed by the present invention improves the flexibility of the entire cutting device, is more adaptable to the environment, and is suitable for use in situations where the working surface is narrow; and through the said changing pulley group, the cutting device can be arranged faster and more conveniently, thereby improving work efficiency and reducing work costs.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and beneficial effects of the invention clearer, the following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0026] See also Figure 1 、 Figure 2 and Figure 5A multifunctional cutting pulley steering device includes a wall-mounted fixed support 3, a wire saw 11, and a diamond rope 2. The fixed support 3 is fixed to the wall via expansion screws. A horizontal beam 4 is mounted on the fixed support 3. The end of the horizontal beam 4, away from the fixed support 3, is connected to a vertical beam 6 via a fixed connecting block 5. The horizontal beam 4 and the vertical beam 6 are perpendicular to each other. The vertical beam 6 can be mounted on the fixed connecting block 5 via bolts. Screw holes are provided in the fixed connecting block 5 and the vertical beam 6. Bolts pass through the screw holes to securely connect the fixed connecting block 5 and the vertical beam 6 together. The fixed connecting block 5 is a rectangular parallelepiped. The first pulley group 7 and the second pulley group 8 are installed at the upper and lower ends of the vertical beam 6; the first pulley group 7 and the second pulley group 8 are installed on the vertical beam 6 through a fixing sleeve 9, and the fixing sleeve 9 is fastened to the vertical beam 6 by bolts. The first pulley group 7 includes a first pulley 72 and a first positioning frame 71, and the first pulley 72 is rotatably connected to the first positioning frame 71 through a pulley shaft; the second pulley group 8 includes a second pulley 82 and a second positioning frame 81, and the second pulley 82 is rotatably connected to the second positioning frame 81 through a pulley shaft, and the first positioning frame 71 and the second positioning frame 81 are welded to the outer surface of the fixing sleeve 9. Since the fixing sleeve 9 is fastened to the vertical beam 6 by bolts, when the bolts are loosened, the fixing sleeve 9 can be rotated about the central axis of the vertical beam 6 and the position of the fixing sleeve 9 can be adjusted up and down, thereby adjusting the angle between the center line of the first pulley 72 and the wall where the target cutting object 1 is located to adapt to the cutting of the target cutting object 1 that is tilted left and right relative to the wall; adjusting the fixing sleeve 9 up and down serves the purpose of changing the distance between the two first pulleys 72 to adapt to target cutting objects 1 with different pipe diameters. In this embodiment, the target cutting object 1 is a reinforced concrete pipe segment.

[0027] Please continue reading Figure 1 The wire saw 11 is mounted on a trolley 12. The trolley 12 is used to drive the wire saw 11 back and forth. The diamond rope 2 is used to cut the target object 1. The diamond rope 2 passes through the first pulley block 7 at the upper end of the vertical beam 6, the second pulley block 8, the driving pulley 10, the second pulley block 8 at the lower end of the vertical beam 6, the first pulley block 7, and the target object 1, and then closes into a loop. The wire saw 11 is used to drive the driving pulley 10 to rotate, thereby driving the diamond rope 2 to cut the target object 1.

[0028] Furthermore, the first pulley group 7 at the upper end of the vertical beam 6 is located directly above the first pulley group 7 at the lower end of the vertical beam 6, ensuring that the diamond rope 2 for cutting the target object 1 is in the same plane as the cutting surface, so that the cutting surface remains flat, and the diamond rope 2 between the second pulley group 8 at the upper end of the vertical beam 6 and the driving wheel 10 and the diamond rope 2 between the second pulley group 8 at the lower end of the vertical beam 6 and the driving wheel 10 are located on the same plane, making it difficult for the diamond rope 2 to separate from the driving wheel 10, thereby improving the stability of the cutting process.

[0029] See also Figure 2 A first indicator needle 14 is installed on the fixed sleeve 9, and a first scale line 13 is circumferentially provided on the vertical beam 6 near the fixed sleeve 9. In order to adapt to the movement of the fixed sleeve 9 on the vertical beam 6, the line length of the first scale line 13 can be appropriately lengthened.

[0030] See also Figure 3 and Figure 4 A bearing is installed in the fixed connection block 5 and a groove 17 is provided. The crossbeam 4 is interference-fitted with the inner ring of the bearing and a turntable 18 is provided on the outer surface of the crossbeam 4. The bearings are located at both ends of the turntable. The bearings limit the forward and backward movement of the fixed connection block 5 along the central axis of the crossbeam 4. The turntable 18 is set in the groove 17. The turntable 18 is provided with a plurality of slots 19 at equal intervals around the circumference. A limit plate 20 is rotatably connected to the side wall of the groove 17. A block 21 is provided on the side of the limit plate 20 close to the groove 17. The block 21 is adapted to the slot 19. A baffle 22 is rotatably connected to the outer surface of the crossbeam 4. The baffle 22 is used to abut the bottom end of the limit plate 20. A knob 23 is installed on the baffle 22. By turning the knob 23, the baffle 22 can be driven to rotate. When the baffle is rotated, 22 is in a vertical state, and the upper end of the baffle 22 abuts against the bottom end of the limit plate 20, which can prevent the limit plate 20 from rotating outward, so that the card block 21 is embedded in the card slot 19 and remains stable; when the baffle 22 rotates to a horizontal state, the upper end of the baffle 22 no longer abuts against the bottom end of the limit plate 20, and the limit plate 20 can rotate outward, thereby facilitating the adjustment of the angle of the fixed connecting block 5 relative to the beam 4, and changing the angle between the center line of the first pulley 72 and the wall where the target cutting object 1 is located, to adapt to the cutting of the target cutting object 1 that is tilted up and down relative to the wall.

[0031] For further information, see Figure 3 A second indicator needle 15 is installed on the fixed connection block 5, and a second scale line 16 is circumferentially provided at the position of the beam 4.

[0032] Furthermore, a V-shaped wire groove is provided on the first pulley 72 and the second pulley 82 , and the V-shaped wire groove can limit the displacement of the diamond rope 2 and prevent the diamond rope 2 from being separated from the first pulley 72 or the second pulley 82 .

[0033] The working principle of the present invention is as follows: the fixed support 3 is fixed to the wall (the wall is not in the same plane as the wall where the target cutting object is located) by four expansion screws to ensure the stability of the entire cutting pulley steering device, and when fixing, ensure that the wire grooves of the two first pulleys 72 at the upper and lower ends of the vertical beam 6 and the ideal cutting surface of the target cutting object 1 (reinforced concrete pipe segment) are in the same plane to ensure cutting flatness; at the same time, ensure that the diamond rope 2 between the second pulley 72 at the upper end of the vertical beam 6 and the driving wheel 10 and the diamond rope 2 between the second pulley 82 at the lower end of the vertical beam 6 and the driving wheel 10 are in the same plane, so that the diamond rope 2 is not easy to separate from the driving wheel 10. After the cutting pulley steering device is fixed, the diamond rope 2 is connected to the first pulley 72, the second pulley 82, the target cutting object 1 and the target cutting object 1. The driving wheel 10 and the trolley 12 drive the wire saw machine 5 to move forward and backward, and the wire saw machine 5 is fixed according to the on-site environment, and the diamond rope 2 is tensioned; finally, a safety fence is arranged around the construction site to avoid safety accidents. After the fence is arranged, the target cutting object 1 can be cut. For the cutting of the target cutting object 1 that exceeds the limit at the tunnel interface, it is necessary to follow the principle of "from bottom to top, left and right symmetry, and block cutting". The target cutting object 1 located at the bottom of the tunnel, after cutting, falls directly on the bottom plate of the working well, and is then lifted away from the wellhead by a crane. Before cutting, the remaining target cutting object 1 needs to be connected to the bolt holes on the side of the pipe segment with a special connecting plate, and then lassoed with a wire rope, and the target cutting object 1 is kept in a lifting state with the help of the crane. After the crane is ready, cutting can begin.
