Description

Technical Field

[0001] This application relates to the field of bridge construction technology, and in particular to an auxiliary hoisting device for bridge installation and construction. Background Technology

[0002] Bridges generally refer to structures built over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. To adapt to the modern, rapidly developing transportation industry, bridges have also been extended to refer to buildings that cross mountains, adverse geological conditions, or meet other transportation needs to make travel more convenient. Because the materials used to build bridges are generally heavy, the steel wire ropes used for hoisting over a long period of time can wear down or break, posing a significant safety hazard.

[0003] Among existing bridge hoisting devices, such as Chinese Patent No. CN213011675U, a hoisting device for bridge construction is disclosed. Specifically, it includes a lower chassis and a mounting frame. An upper chassis is movably connected to the upper part of the lower chassis, and locking columns are fixedly connected to the upper left and right ends of the upper chassis. A support column is fixedly connected to the upper part of the upper chassis, and an electric extension frame is fixedly connected to the upper part of the support column. Electric slide rails are fixedly connected to the left and right sides inside the mounting frame, and the mounting frame is located at the upper end of the electric extension frame.

[0004] While the aforementioned existing technologies can achieve the function of hoisting bridge materials, firstly, they cannot detect partially broken wire ropes during the hoisting process. This could lead to further breakage of the wire ropes when hoisting heavier materials, potentially resulting in complete breakage and posing a significant safety hazard, thus hindering the safe hoisting of bridge materials. Secondly, the existing technologies cannot clean and maintain the wire ropes after hoisting, leaving impurities or oil stains that are detrimental to their preservation and could cause corrosion. Therefore, there is room for improvement in the existing bridge hoisting device technology. Summary of the Invention

[0026] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0027] This application discloses an auxiliary hoisting device for bridge installation and construction, which can realize the functions of hoisting bridge materials and inspecting, cleaning and protecting the steel wire ropes used.

[0028] Reference Figure 1 and Figure 2 As shown in this embodiment, an auxiliary hoisting device for bridge installation and construction includes: a support frame 1, which has a U-shaped structure; trusses 2, which are symmetrically installed on the upper end of the support frame 1; a movable frame 3, which is symmetrically slidably arranged on the upper ends of the two trusses 2, the movable frame 3 having a rectangular hollow structure, and the movable frame 3 being used to move longitudinally on the upper end of the trusses 2; a winding module 4, which is slidably arranged on the upper end of the movable frame 3, with a steel wire rope wound on the winding module 4, the winding module 4 being used to wind the steel wire rope and drive the steel wire rope to move laterally on the movable frame 3; an inspection and cleaning module 5, which is installed at the lower end of the winding module 4, the steel wire rope passing through the inspection and cleaning module 5, the inspection and cleaning module 5 being used to inspect, clean and maintain the steel wire rope; and a hoisting frame 6, which is installed at the end of the steel wire rope.

[0029] In actual use, when hoisting bridge materials, the winding module 4 loosens the wire rope, and the hoisting frame 6, under the action of gravity, drives the wire rope through the inspection and cleaning module 5. At this time, the inspection and cleaning module 5 inspects the wire rope. When a break is detected in the wire rope, the broken wire rope is manually repaired or treated. Then, the bridge materials are tied and fixed to the lower end of the hoisting frame 6. The moving frame 3 drives the bridge materials to move along the truss 2 for longitudinal hoisting. The winding module 4 moves laterally on the moving frame 3, so that the bridge materials can be accurately hoisted to the required installation position. After the bridge materials are hoisted, the winding module 4 winds up the wire rope, and the inspection and cleaning module 5 cleans and maintains the wire rope for easy storage. The inspection and cleaning module 5 also inspects the wire rope again.

[0030] It should be noted that the lower end of the hoisting frame 6 is symmetrically equipped with crossbars, and limit rods are evenly installed on the crossbars. When fixing the bridge materials, steel cables can be used to fix the bridge materials to the crossbars, and the corresponding limit rods are used to limit the steel cables according to the width of the bridge materials, so that the bridge materials can be kept in balance when hoisting, which facilitates the accurate positioning and installation of the bridge materials.

[0031] It should also be noted that the winding module 4 includes a winding motor and a winding roller. The winding roller is connected to the output shaft of the winding motor. The wire rope is wound on the winding roller. The rotation of the winding motor drives the winding roller to wind or unwind the wire rope.

[0032] Reference Figure 3 As shown, the detection and cleaning module 5 includes a rectangular frame 51, a cylindrical frame 52, a detection unit 53, a fixed frame 54, and a cleaning unit 55. The lower end of the movable frame 3 is equipped with a rectangular frame 51, which is a hollow structure. The upper middle part of the rectangular frame 51 is equipped with a cylindrical frame 52, which has through slots evenly distributed on it. The detection unit 53 is installed in the through slots. The lower middle part of the rectangular frame 51 is equipped with a fixed frame 54, which has mounting slots evenly distributed on it. The mounting slots correspond to the through slots, and the cleaning unit 55 is installed in the mounting slots.

[0033] In actual use, before hoisting the bridge materials, the winding module 4 loosens the wire rope, and the hoisting frame 6 moves the wire rope downward under the action of gravity. The wire rope passes through the detection unit 53 and the cleaning unit 55, and the detection unit 53 detects the wire rope. When there is a break in the wire rope, the broken wire rope squeezes the detection unit 53. At this time, the detection unit 53 issues an alarm, and the broken wire rope is manually repaired. After the bridge materials are hoisted, the winding module 4 winds up the wire rope, and the cleaning unit 55 cleans and maintains the wire rope for easy storage. The detection unit 53 also detects the wire rope again, realizing the functions of detection alarm, cleaning and maintenance of the wire rope, ensuring the safety of the wire rope during use, and facilitating the preservation of the wire rope and preventing corrosion.

[0034] Reference Figure 3 As shown, the detection unit 53 includes a detection component 531 and a limiting component 532. The detection component 531 is symmetrically installed at the end of the through groove by bolts, and the limiting component 532 is installed in the middle of the through groove.

[0035] In actual use, when the wire rope is being tested, the wire rope moves downward or upward. A broken wire rope will squeeze the detection component 531, triggering an alarm. The broken wire rope will then be manually repaired. The limiting component 532 will limit the wire rope, allowing it to pass through the middle of the detection component 531 and preventing the wire rope from shaking and affecting the detection structure of the detection component 531.

[0036] Reference Figure 5 As shown, the detection assembly 531 includes a detection frame 5311, a vertical rod 5312, a sector-shaped frame 5313, a touch switch 5314, a tension spring 5315, a locking rod 5316, and a tension spring 5317. The detection frame 5311 is bolted to the end of the through slot. The detection frame 5311 has a cylindrical hollow structure. An annular groove is provided on the end face of the detection frame 5311. The vertical rod 5312 is evenly installed in the middle of the annular groove. The sector-shaped frame 5313 is slidably mounted on the vertical rod 5312. The inner side of the fan-shaped frame 5313 is inclined, and touch switches 5314 are evenly installed in the annular groove. The touch switches 5314 cooperate with the fan-shaped frame 5313. A tension spring 5315 is installed between the fan-shaped frame 5313 and the upright 5312. A slot is provided in the middle of the outer side of the fan-shaped frame 5313. A locking rod 5316 is slidably provided in the middle of the outer side of the detection frame 5311. The locking rod 5316 cooperates with the slot. A tension spring 5317 is installed between the locking rod 5316 and the detection frame 5311.

[0037] In actual use, the touch switch 5314 is electrically connected to the alarm, and the tension spring 5317 is in a stretched state. When the wire rope is being tested, the broken wire rope compresses the sector frame 5313, causing it to move into the annular groove. The tension spring 5315 gradually compresses. When the sector frame 5313 presses against the touch switch 5314, the touch switch 5314 opens, and the alarm, which is electrically connected to the touch switch 5314, sounds an alarm. At this time, the tension spring 5317 drives the locking rod 531. 6. The locking rod 5316 is accurately inserted into the slot, limiting and fixing the sector frame 5313, so that the touch switch 5314 is in a continuously open state. The locking rod 5316 can be manually pulled to remove the end of the locking rod 5316 from the slot. The sector frame 5313 is reset under the action of the tension spring 5315, and the touch switch 5314 is closed. This realizes the function of detecting and alarming the wire rope, which makes it easy for workers to quickly and accurately repair the wire rope and eliminates the safety hazards during the wire rope hoisting process.

[0038] Reference Figure 6 As shown, the limiting component 532 includes a sleeve 5321, a tapered frame 5322, and ball bearings 5323. The sleeve 5321 is installed in the middle of the through groove, the tapered frame 5322 is evenly installed inside the sleeve 5321, and the ball bearings 5323 are evenly installed on the tapered frame 5322.

[0039] In actual use, the balls 5323 limit the movement of the wire rope, ensuring that the wire rope is always in the center of the through groove. This prevents the wire rope from shaking or the burrs on the wire rope from squeezing the fan-shaped frame 5313 and causing false alarms. In addition, the balls 5323 can reduce the friction on the wire rope.

[0040] Reference Figure 7 As shown, the cleaning unit 55 includes a ring frame 551, a cleaning component 552, a collection component 553, and an application component 554. The ring frame 551 is installed in the mounting slot. The cleaning component 552 is installed at the lower end of the ring frame 551. The collection component 553 is installed inside the ring frame 551 and cooperates with the cleaning component 552. The application component 554 is installed at the upper end of the ring frame 551.

[0041] In actual use, when cleaning and protecting the wire rope, the cleaning component 552 cleans the wire rope of dust, oil and other impurities, the collecting component 553 collects the impurities on the cleaning component 552, so that the cleaning component 552 is always clean and the cleaning effect of the cleaning component 552 is improved, and the coating component 554 applies protective agent to the cleaned wire rope to prevent the wire rope from rusting after winding and to ensure the quality of the wire rope.

[0042] Reference Figure 7 and Figure 8 As shown, the cleaning assembly 552 includes a rotating frame 5521, cleaning bristles 5522, gear one 5523, and gear two 5524. The rotating frame 5521 is mounted on the lower end of the inner ring frame 551 via a bearing. The cleaning bristles 5522 are evenly arranged inside the rotating frame 5521. Gear one 5523 is mounted on the lower end of the outer side of the rotating frame 5521 located in the middle of the fixed frame 54. Gear two 5524 is mounted on the lower end of the outer side of the rotating frame 5521 located outside the fixed frame 54. Gear two 5524 meshes with gear one 5523.

[0043] In actual use, a motor is installed on the ring frame 551, and a connecting gear is installed on the output shaft of the motor. The connecting gear meshes with a second gear 5524. The motor drives the connecting gear to rotate, causing all the second gears 5524 and the first gear 5523 to rotate. The rotating frame 5521 rotates synchronously. The cleaning brushes 5522 inside the rotating frame 5521 brush and sweep the wire rope to remove dust, oil and other impurities, keep the wire rope clean, and prevent rust after the wire rope is wound up.

[0044] Reference Figure 7 As shown, the collecting component 553 includes a horizontal frame 5531, a combing plate 5532, comb teeth 5533, and a collecting frame 5534. The horizontal frame 5531 is installed inside the annular frame 551. The horizontal frame 5531 has an annular structure. The combing plate 5532 is symmetrically installed at the lower end of the horizontal frame 5531. The combing plate 5532 has a trapezoidal cross-section and its outer surface is inclined. Comb teeth 5533 are evenly arranged on the outer surface of the combing plate 5532. The comb teeth 5533 are arranged at an incline. Guide grooves are evenly arranged on the combing plate 5532. The collecting frame 5534 is installed between the lower ends of the combing plates 5532. The collecting frame 5534 is connected to the rotating frame 5521 through a bearing. A collecting groove is provided in the middle of the collecting frame 5534, and the collecting groove is connected to the guide groove.

[0045] In actual use, when the cleaning brush 5522 brushes the wire rope, impurities will adhere to the cleaning brush 5522. When the cleaning brush 5522 rotates between the comb teeth 5533, the comb teeth 5533 clean the impurities on the cleaning brush 5522. The impurities enter the collection groove in the collection frame 5534 along the guide groove, which facilitates the subsequent centralized treatment of impurities. This realizes the function of cleaning and collecting impurities on the cleaning component 552, and ensures the continuous cleaning effect of the cleaning component 552 on the wire rope.

[0046] Reference Figure 7As shown, the coating component 554 includes a feed rack 5541 and hollow bristles 5542. The feed rack 5541 is installed at the upper end of the inner ring frame 551. The feed rack 5541 has a ring structure and a feed groove is provided in the middle of the feed rack 5541. Hollow bristles 5542 are evenly arranged on the inner side of the feed rack 5541 and are connected to the feed groove.

[0047] In actual use, when it is necessary to apply a protective agent to the wire rope, the protective agent is introduced into the feed trough in the feed rack 5541. The protective agent is applied to the wire rope through the hollow brush 5542 to protect the wire rope and prevent it from rusting after winding and storage, thus ensuring the quality of the wire rope.

[0048] The implementation principle of this embodiment is as follows: 1. Relaxation Detection: The winding module 4 relaxes the wire rope, and the hoisting frame 6 moves the wire rope downward under the action of gravity. The wire rope passes through the detection unit 53 and the cleaning unit 55. The detection unit 53 detects the wire rope. When there is a break in the wire rope, the broken wire rope squeezes the detection unit 53. At this time, the detection unit 53 issues an alarm, and the broken wire rope is manually repaired.

[0049] 2: Fixed hoisting, the bridge materials are tied and fixed to the lower end of the hoisting frame 6, the moving frame 3 drives the bridge materials to move along the truss 2, and the bridge materials are hoisted longitudinally. The winding module 4 moves laterally on the moving frame 3, so that the bridge materials can be accurately hoisted to the required installation position.

[0050] 3: Cleaning and protection. After hoisting, the winding module 4 winds up the wire rope, the cleaning component 552 cleans the wire rope of dust, oil and other impurities, the collecting component 553 collects the impurities on the cleaning component 552 to keep the cleaning component 552 clean, and the coating component 554 applies a protective agent to the cleaned wire rope to prevent rust after winding.

[0051] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
