Description

Technical Field

[0001] The invention belongs to the technical field of hoisting equipment, and in particular relates to a roller skating device used in the hoisting process of an oil tanker. Background Art

[0002] An oil tanker is a ship specially used for transporting bulk liquid cargo, especially petroleum and its derivatives. The construction of an oil tanker involves many complex processes and steps, which are usually carried out in a shipyard. The assembly of an oil tanker is usually carried out in sections, and the various components are transported to the dock in sections. For example, the large-scale installation of the main frame of the hull, deck, bulkheads, etc., as well as the specific layout of the oil tanks, are combined into an integral hull through welding and other methods. This process requires very precise alignment and operation, so lifting equipment is needed to greatly improve the assembly efficiency of the oil tanker.

[0003] The structure of the existing lifting equipment used in the assembly of oil tankers is relatively ordinary, especially the design of the pulley assembly is relatively simple. When the lifting equipment is lifting the parts of the oil tanker and the lifting equipment is out of control, the staff will press the emergency stop button and activate the brake to stop the rope from releasing or reeling in, so that the entire pulley assembly stops running. Since the parts of the oil tanker are relatively large in specifications and heavy in weight, and the existing lifting equipment is simply designed with a brake, although it can be emergency stopped under special circumstances, it cannot guarantee the safety of each operation. If a brake mechanism is designed on the pulley assembly, the safety of the oil tanker assembly and lifting will be greatly improved. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a roller skating device for the tanker lifting process.

[0005] The technical solution adopted to solve the above technical problems is: a roller pulley device for the tanker hoisting process, comprising a mounting frame, a fixed pulley assembly is fixedly mounted at the center of the mounting frame, and a connecting mechanism is installed on the top of the mounting frame;

[0006] A main brake mechanism is installed on the fixed pulley assembly, and auxiliary pulley assemblies are fixedly installed at the front and rear ends of the mounting frame;

[0007] A movable pulley assembly is provided below the mounting frame, and a rope is wound around the fixed pulley assembly, the auxiliary pulley assembly and the movable pulley assembly;

[0008] A secondary brake mechanism is installed between the center of the mounting frame and the auxiliary pulley assembly, and a hook is fixedly connected to the bottom of the movable pulley assembly.

[0009] Furthermore, the fixed pulley assembly includes a first connecting shaft fixedly connected to the center of the mounting frame, and a plurality of evenly distributed fixed pulley bodies are rotatably connected to the outer wall of the first connecting shaft, and an annular groove is formed on one side of the plurality of fixed pulley bodies.

[0010] Through the above technical solution, multiple fixed pulley bodies cooperate with the movable pulley assembly, so that the lifting direction and force direction of the hanging object can be adjusted at will, which is easier to control and operate, and the main brake mechanism is easy to install in the annular groove.

[0011] Furthermore, the connecting mechanism includes connecting ears rotatably connected to the two ends of the outer wall of the first connecting shaft, the top between the two connecting ears is rotatably connected to the installation shaft, and the two ends of the outer wall of the installation shaft are respectively rotatably connected to the first guide pulley and the second guide pulley.

[0012] Through the above technical solution, the entire device is installed on the top of the lifting equipment through the installation shaft. When the staff needs to adjust the magnification of the device, one end of the rope passes through the first guide pulley, passes through the fixed pulley assembly, the auxiliary pulley assembly and the movable pulley assembly, comes out of the second guide pulley, and then returns to the winding mechanism of the lifting equipment.

[0013] Furthermore, the main braking mechanism includes a plurality of brake gear rings respectively fixedly connected in the annular grooves, an outer wall of the first connecting shaft and a position close to the corresponding brake gear ring is rotatably connected with a mounting plate, a plurality of the mounting plates are each provided with a plurality of slots, a plurality of the mounting plates are each fixedly connected with a driven gear ring on the other side, an outer wall of the first connecting shaft and a position close to the corresponding mounting plate is fixedly connected with a fixed plate, a plurality of mounting grooves are each provided with a plurality of fixed plates, a plurality of the mounting grooves are each fixedly connected with a spring, a plurality of the springs are each fixedly connected with a brake pin on one end, a rotating shaft is rotatably connected to the center of the mounting frame and close to the lower position of the first connecting shaft, a plurality of evenly distributed driving gears are fixedly connected to the outer wall of the rotating shaft, and a motor is fixedly installed on one side of the mounting frame.

[0014] Through the above technical solution, when the hook lifts the tanker assembly parts, the movable pulley assembly is lifted and lowered through the connected rope. At this time, the lifting equipment is out of control. The staff starts the rope brake device and starts the motor. The motor drives the rotating shaft to rotate through the output shaft. The rotation of the rotating shaft drives multiple driving gears to rotate. The rotation of the multiple driving gears drives the meshing driven gear rings to rotate. The rotation of the driven gear ring drives the connected mounting disk to rotate. The mounting disk is against the brake pin when it is stationary before rotation. Since multiple notches are opened on the mounting disk, the positions of the multiple notches change after the mounting disk rotates. At this time, multiple brake pins pass through the corresponding slots under the action of the connected springs. Since the movable pulley assembly moves downward when the rope is released, the fixed pulley body rotates clockwise, and the brake gear ring also rotates clockwise. At this time, multiple brake pins pop out and fit with the teeth on the brake gear ring, causing the brake gear ring to be unable to rotate clockwise, making the multiple fixed pulley bodies unable to rotate, thereby increasing the friction between the rope and the multiple fixed pulley bodies, and cooperating with the original braking device on the lifting equipment, further improving the stability of the roller skating equipment, thereby reducing the occurrence of safety accidents.

[0015] Furthermore, the mounting plate is rotationally connected to the corresponding fixed pulley body and the fixed plate, the driven gear ring is meshed with the corresponding driving gear, the brake pin is slidingly connected to the corresponding mounting groove, and one end of the motor output shaft is fixedly connected to the other end of the rotating shaft.

[0016] Through the above technical solution, after braking, the tanker assembly is removed from the hook. In order to facilitate the subsequent use of the roller skating equipment, the main brake mechanism needs to be reset. The rope is pulled by the winding mechanism on the lifting equipment to drive the fixed pulley body to rotate counterclockwise, and then the brake gear ring is driven to rotate counterclockwise. When the contact area between the teeth on the brake gear ring and the brake pin is one-third, the mounting plate is driven by the motor to rotate counterclockwise, so that the notch on the mounting plate cuts into the contact surface between the brake pin and the brake gear ring, so that the solid part of the mounting plate presses the brake pin against the mounting groove, and the main brake mechanism is reset, which is convenient for the subsequent braking of the pulley device.

[0017] Furthermore, the auxiliary pulley assembly includes second connecting shafts fixedly connected to the front and rear ends of the mounting frame, and two of the second connecting shafts are rotatably connected to auxiliary pulley bodies that are evenly distributed.

[0018] Through the above technical solution, the rope passes through the corresponding multiple auxiliary pulley bodies, which is convenient for the auxiliary braking mechanism to perform secondary braking on them, greatly improving the stability and safety of the roller skating equipment and preventing the tanker assembly parts from falling and accidentally injuring workers.

[0019] Furthermore, the movable pulley assembly includes a movable frame arranged below the mounting frame, the center of the movable frame is fixedly connected to a third connecting shaft, and the outer wall of the third connecting shaft is rotatably connected to a plurality of evenly distributed movable pulley bodies.

[0020] Through the above technical solution, the rope passes through multiple fixed pulley bodies and corresponding multiple movable pulley bodies, so that the force requirement of the lifted tanker assembly parts is reduced, thereby reducing the work intensity of the staff.

[0021] Furthermore, the auxiliary braking mechanism includes a sliding rail fixedly connected between the inner walls on both sides of the mounting frame, a movable shaft is slidably connected to the sliding rail, a plurality of evenly distributed movable ears are rotatably connected to the front and rear end centers of the movable shaft, one end of each of the plurality of movable ears is rotatably connected to a connecting seat, a plurality of outer end surfaces of the connecting seats are fixedly connected to brake blocks, a plurality of evenly distributed bases are fixedly connected to the bottom of the front and rear ends of the movable shaft, a hydraulic cylinder is fixedly connected to the inner wall on the other side of the mounting frame, one end of the hydraulic cylinder piston is fixedly connected to a connecting head, and a limiting hole corresponding to the movable shaft and the connecting head is opened on the other side of the mounting frame.

[0022] Through the above technical solution, after the main brake mechanism brakes, in order to improve the safety of the device, the hydraulic cylinder is started at this time, so that the hydraulic cylinder pushes the connecting head through the piston, and then pushes the movable shaft, so that the movable shaft drives the multiple connected movable ears to rotate, and then drives the connecting seat connected to it to slide on the corresponding base, and then drives the brake block to squeeze the approaching rope, so that the rope is forced to fit with the corresponding auxiliary pulley body, increasing the friction between the rope and the multiple auxiliary pulley bodies, cooperating with the original braking device on the lifting equipment, and the braking effect of the main brake mechanism, further improving the braking effect of the movable pulley assembly, preventing the lifted tanker assembly parts from falling and injuring the staff.

[0023] Furthermore, the plurality of connecting seats are slidably connected to the corresponding bases, the plurality of brake blocks are respectively close to the inner end positions of the auxiliary pulley body, and the connecting head is fixedly connected to one end of the movable shaft.

[0024] Through the above technical solution, one end of the movable shaft passes through the limiting hole when being pushed, and multiple brake blocks fit with multiple contact surfaces of the rope, so that the rope fits with multiple auxiliary pulley bodies, increasing the friction contact surface and greatly improving the anti-slip effect of the rope.

[0025] The beneficial effects of the present invention are as follows: (1) The present invention designs a main braking mechanism. When the lifting equipment loses control, multiple brake pins pop out and fit with the teeth on the brake gear ring, making the brake gear ring unable to rotate, resulting in multiple fixed pulley bodies unable to rotate, thereby increasing the friction between the rope and the multiple fixed pulley bodies. In conjunction with the original braking device on the lifting equipment, the stability of the roller skating equipment is further improved, thereby reducing the occurrence of safety accidents. At the same time, the main braking mechanism can be reset for subsequent reuse without replacement, thereby reducing the use cost of the lifting equipment; (2) The present invention uses a secondary braking mechanism to fit the rope with the auxiliary pulley body through multiple brake blocks, thereby increasing the friction between the rope and the auxiliary pulley body. In conjunction with the original braking device on the lifting equipment and the braking effect of the main braking mechanism, the braking effect of the movable pulley assembly is further improved, preventing the lifted tanker assembly parts from falling and injuring the staff.

[0041] like Figure 1-9As shown, a main brake mechanism 4 is installed on the fixed pulley assembly 2, and the main brake mechanism 4 includes a plurality of brake gear rings 401 respectively fixedly connected in the annular groove 203, a mounting plate 402 is rotatably connected to the outer wall of the first connecting shaft 201 and close to one side of the corresponding brake gear ring 401, a plurality of mounting plates 402 are each provided with a plurality of notches 403, a plurality of mounting plates 402 are each fixedly connected to a driven gear ring 404 on the other side, a fixed plate 405 is each provided with a plurality of mounting grooves 406 on the outer wall of the first connecting shaft 201 and close to the other side of the corresponding mounting plate 402, a plurality of fixing plates 405 are each fixedly connected to a plurality of mounting grooves 406, a plurality of springs 407 are each fixedly connected to a brake pin 407 at one end thereof. 8.

The outer end surfaces of the plurality of connection seats 804 are all fixedly connected with brake blocks 805, the front and rear end bottoms of the movable shaft 802 are fixedly connected with a plurality of evenly distributed bases 806, the inner wall of the other side of the mounting frame 1 is fixedly connected with a hydraulic cylinder 807, one end of the piston of the hydraulic cylinder 807 is fixedly connected with a connector 808, and the other side of the mounting frame 1 is provided with a limiting hole 809 corresponding to the movable shaft 802 and the connector 808. After the main brake mechanism 4 is braked, in order to improve the safety of the device, the hydraulic cylinder 807 is started at this time, so that the hydraulic cylinder 807 pushes the piston The movable connector 808 further pushes the movable shaft 802, so that the movable shaft 802 drives the multiple movable ears 803 connected thereto to rotate, and then drives the connecting seat 804 connected thereto to slide on the corresponding base 806, and then drives the brake block 805 to squeeze the nearby rope 7, so that the rope 7 is forcefully fitted with the corresponding auxiliary pulley body 502, thereby increasing the friction between the rope 7 and the multiple auxiliary pulley bodies 502, and cooperating with the original braking device on the lifting equipment and the braking effect of the main braking mechanism 4, further improving the braking effect of the movable pulley assembly 6 The braking effect is to prevent the lifted tanker assembly parts from falling and injuring the staff. Multiple connecting seats 804 are slidably connected with the corresponding bases 806. Multiple brake blocks 805 are respectively close to the inner end positions of the auxiliary pulley body 502.

[0046] When the hook 9 lifts the tanker assembly parts, the movable pulley assembly 6 is lifted and lowered by the connected rope 7. At this time, the lifting equipment is out of control. The staff starts the braking device of the rope 7 and starts the motor 411. The motor 411 drives the rotating shaft 409 to rotate through the output shaft. The rotation of the rotating shaft 409 drives multiple driving gears 410 to rotate. The rotation of multiple driving gears 410 drives the meshing driven gear ring 404 to rotate. The rotation of the driven gear ring 404 drives the connected mounting plate 402 to rotate. The mounting plate 402 is against the brake pin 408 when it is stationary before rotation. Since the mounting plate 402 is provided with multiple notches 403, after the mounting plate 402 rotates, the positions of the multiple notches 403 are changed. At this time, the multiple brake pins 408 pass through the corresponding notches 403 under the action of the connected springs 407.

At the same time, the hydraulic cylinder 807 is started, so that the hydraulic cylinder 807 pushes the connecting head 808 through the piston, and then pushes the movable shaft 802, so that the movable shaft 802 drives the connected multiple movable ears 803 to rotate, and then drives the connecting seat 804 connected thereto to slide on the corresponding base 806, and then drives the brake block 805 to squeeze the approaching rope 7, so that the rope 7 is forced to fit with the corresponding auxiliary pulley body 502, thereby increasing the friction between the rope 7 and the multiple auxiliary pulley bodies 502, and further braking the movable pulley assembly 6;

[0047] After braking, the tanker assembly is removed from the hook 9. In order to facilitate the subsequent use of the roller skating equipment, the main brake mechanism 4 needs to be reset. The rope 7 is pulled by the winding mechanism on the lifting equipment to drive the fixed pulley body 202 to rotate counterclockwise, and then the brake gear ring 401 is driven to rotate counterclockwise. When the contact area between the teeth on the brake gear ring 401 and the brake pin 408 is one-third, the mounting plate 402 is driven by the motor 411 to rotate counterclockwise, so that the notch 403 on the mounting plate 402 cuts into the contact surface between the brake pin 408 and the brake gear ring 401, so that the solid part of the mounting plate 402 presses the brake pin 408 against the mounting groove 406, and the main brake mechanism 4 is reset, which is convenient for the subsequent braking of the pulley equipment.
