Description

Technical Field

[0002] The utility model patents with announcement numbers CN201198435Y and CN201520595U both disclose a monorail hoist for hoisting rails. The main structure of such hoists is consistent in that a hoist shaft drives a locker and then drives two relatively arranged hook heads at the bottom to clamp the rail head.

[0003] However, at the rail welding site, it is necessary to unload 100-meter-long rails from the train cargo box, weld 5 rails end to end to form a 500-meter-long rail, and then hoist them onto the shipping train carriage. A 100-meter-long rail requires 7 overhead cranes equipped with their own monorail hoists for group hoisting. And a 500-meter-long rail requires more than 30 overhead cranes equipped with their own monorail hoists for group hoisting. The overhead crane electric control cabinet can control the synchronous movement of all overhead cranes to ensure smooth hoisting operations. However, the existing monorail hoists do not have an automatic detection function. If individual monorail hoists are not clamped properly, it will increase the burden on adjacent overhead cranes, and in serious cases, it will cause rail drop hoisting accidents. If so many monorail hoists are manually checked one by one, it will cause a waste of manpower and reduce hoisting efficiency.

[0004] Therefore, it is necessary to develop a monorail hanger for long rail hoisting and a long rail hoisting system to overcome the above-mentioned defects. Utility Model Content

[0029] With reference to the accompanying drawings, Figure 1 This is a schematic diagram of the main structure of the monorail hoist for hoisting long rails of the utility model; Figure 2 This is a right side structural schematic diagram of a monorail hoist for hoisting long rails of the utility model; Figure 3 It is a schematic diagram of the composition of the long rail hoisting system of the utility model.

[0030] In a specific embodiment, Figure 1 and Figure 2 As shown, the utility model monorail sling for long rail hoisting includes a sling body 1, a tension sensor 2, a signal transmitting box 3, a lifting ear assembly, a pin bolt 5 and a lifting ring 6. The internal structure of the sling body 1 is consistent with the monorail sling in the prior art, and many comparative documents in the background technology have been described in detail, which will not be repeated here in the utility model. The lifting ear assembly is arranged at the top of the sling body 1 and the top is connected to the lifting ring 6 through the pin bolt 5, and the lifting ring 6 is connected to the hook of the overhead crane. The tension sensor 2 is connected in series in the vertically arranged lifting ear assembly to ensure that the tension load can be accurately obtained by the tension sensor 2. The tension sensor 2 is electrically connected to the signal transmitting box 3, and the signal transmitting box 3 is arranged on the side wall of the sling body 1. A radio transceiver module is arranged in the signal transmitting box 3 and the load data is sent to the device control end by radio. The device control end sends out an alarm message after comparison through the control program. For example, an alarm message is sent out when the load data is less than the set range during the lifting process of the overhead crane.

[0031] By connecting the tension sensor 2 in series in the lifting ear assembly, it is ensured that the tension sensor 2 accurately obtains the tension load; through the setting of the signal transmitting box 3, the load data can be wirelessly sent to the equipment control end, and then when an unexpected situation occurs, an alarm message can be issued, and the operator can eliminate the fault in time, ensuring the safety of the operation.

[0032] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, the lifting lug assembly includes a lower lifting lug 101 and an upper lifting lug 4, the bottom leg plate of the lower lifting lug 101 is connected to the locker drum of the sling body 1, and the top of the lower lifting lug 101 is set as a threaded sleeve and is threadedly connected to the bottom screw segment of the tension sensor 2. The top screw segment of the tension sensor 2 is threadedly connected to the threaded sleeve at the bottom of the upper lifting lug 4, and the top support lug plate of the upper lifting lug 4 is connected to the pin bolt 5. That is, both ends of the tension sensor 2 are set as external threaded rods, and are connected by threaded connection.

[0033] Specifically, if Figure 1 and Figure 2 As shown, the utility model monorail hanger for long rail hoisting also includes anti-loosening thin nuts 7, and two anti-loosening thin nuts 7 are respectively threadedly connected to the bottom screw section and the top screw section of the tension sensor 2, both of which adopt fine pitch threads. The bottom anti-loosening thin nut 7 is locked on the threaded sleeve end face of the lower lifting ear 101, and the top anti-loosening thin nut 7 is locked on the threaded sleeve end face of the upper lifting ear 4.

[0034] The tension sensor 2 is installed by threaded connection, and the lifting force of the overhead crane is completely transmitted through the tension sensor 2, ensuring the accuracy of the measurement. By using the anti-loosening thin nut 7 to lock the threaded sleeve end surface of the lower lifting ear 101 and the upper lifting ear 4, a better anti-loosening effect can be achieved.

[0035] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, the signal transmitting box 3 is provided with a buzzer 302 and a warning light 303, which can send out an alarm signal according to the feedback signal. The warning light 303 is a red warning light, which flashes when it is lit.

[0036] Specifically, the signal transmitting box 3 is equipped with an independent battery compartment 301 and is equipped with dry batteries for power supply, and does not need to be connected with wires separately.

[0037] By arranging a buzzer 302 and a warning light 303 on the signal transmitting box 3, when a clamping failure occurs, sound and flashing alarm information are promptly issued, so that the operator can quickly find the monorail hanger with the clamping failure among many monorail hangers and eliminate the jamming fault.

[0038] In a specific embodiment of the present invention, Figure 1 and Figure 2As shown, the four corners of the signal transmitting box 3 are provided with countersunk bolt mounting holes and are mounted to the outer wall of the sling body 1 by hexagon socket bolts. The signal transmitting box 3 is made of a metal shell and has an IP65 protection level. The signal transmitting box 3 is mounted on one side of the bolt head of the mounting bolt of the sling body 1, and the bolt head height of the mounting bolt is not less than the thickness of the signal transmitting box 3.

[0039] By arranging the signal transmitting box 3 on the outer wall of the sling body 1 and on the same side as the bolt heads of the mounting bolts, the bolt heads around the signal transmitting box 3 form an outer protection, thereby reducing the possibility of impact damage.

[0040] In summary, the utility model of the monorail hoist for long rail hoisting ensures that the tension sensor 2 accurately obtains the tension load by connecting the tension sensor 2 in series in the lifting ear assembly; through the setting of the signal transmitting box 3, the load data can be wirelessly sent to the equipment control end, and then when an unexpected situation occurs, an alarm message can be issued, and the operator can eliminate the fault in time to ensure the safety of the operation. In addition, the tension sensor 2 is installed by threaded connection, and the lifting force of the overhead crane is completely transmitted through the tension sensor 2, which ensures the accuracy of the measurement. By using the anti-loosening thin nut 7 to lock it to the threaded sleeve end surface of the lower lifting ear 101 and the upper lifting ear 4, a better anti-loosening effect can be achieved. By setting the buzzer 302 and the warning light 303 on the signal transmitting box 3, when the clamping failure occurs, the sound and flashing alarm information are issued in time, which is convenient for the operator to quickly find the monorail hoist with clamping failure among many monorail hoists and eliminate the jamming fault. By arranging the signal transmitting box 3 on the outer wall of the sling body 1 and on the same side as the bolt heads of the mounting bolts, the bolt heads around the signal transmitting box 3 form an outer protection, thereby reducing the possibility of impact damage.

[0041] In one embodiment, the utility model also discloses a long rail hoisting system, such as Figure 3 As shown, including:

[0042] The monorail hoist in any of the above embodiments is used to hoist a 100-meter or 500-meter long rail, and a plurality of the monorail hoists are arranged at equal intervals along the rail 11 to be hoisted.

[0043] The equipment control end specifically adopts an industrial computer 9, which establishes a wireless communication connection with all signal transmission boxes 3. Specifically, the industrial computer 9 establishes a wireless communication connection with the signal transmission box 3 through a radio transceiver module in the cabinet, and a Bluetooth module with low energy consumption is used for wireless communication between the two.

[0044] The number of the overhead cranes 8 is consistent with that of the monorail hoist and they are arranged one by one. All the overhead cranes 8 run synchronously and are electrically connected to the overhead crane control cabinet 10 . The industrial computer 9 is electrically connected to the overhead crane control cabinet 10 .

[0045] The working process of the long rail hoisting system of the utility model is as follows: take the hoisting of the welded 500-meter rail 11 as an example for explanation. The operator operates the control panel of the overhead crane control cabinet 10, so that the 35 overhead cranes 8 required for the hoisting can run synchronously and run horizontally to the top of the 500-meter rail 11. The overhead crane 8 releases the wire rope, and the hook 801 descends with the hoisting device body 1 until the hook head of the hoisting device body 1 contacts the top of the rail 11, and then clamps the rail head. The overhead crane 8 reels in the wire rope, and the hook 801 clamps the rail 11, and slowly rises horizontally with the rail 11. At this time, the industrial computer 9 shows that the overhead cranes 8 have all entered the load state, and each hoisting device body 1 has its own ID number in the monitoring program of the industrial computer 9, displaying its own load weight data. When the value transmitted by the tension sensor 2 on some of the sling bodies 1 is significantly smaller than the value of the adjacent sling bodies 1 and exceeds the set range, an alarm message is displayed and a control command is sent to the overhead crane control cabinet 10. At this time, the overhead crane control cabinet 10 can only control the overhead crane 8 to descend synchronously, and cannot move or lift. At the same time, the industrial computer 9 sends a wireless signal to the corresponding signal transmission box 3, and the buzzer 302 and the warning light 303 on the signal transmission box 3 send out sound and flash alarm information. It is convenient for operators to quickly find the monorail sling with clamping failure among many monorail slings, and continue to work after eliminating the jamming fault.

[0046] The long rail hoisting system of the utility model can monitor the working status of each hoisting device body 1 in real time through the wireless communication connection between the industrial computer 9 and each signal transmitting box 3, and can perform emergency control on all the overhead cranes 8 through the electrical connection to the overhead crane control cabinet 10 through the industrial computer 9, thereby having good safety.

The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.

[0048] It should be noted that all components in the technical solution of this application require the necessary additional facilities of water supply, oil supply, electricity supply and gas supply to be driven and / or controlled. If there is no further explanation, it is assumed that the existing technology is used and equipped without special explanation.

[0049] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention.
