Description

Technical Field

[0001] This utility model relates to the field of track crane towing maneuver replacement technology, and in particular to a track crane towing maneuver replacement device. Background Technology

[0002] Rail-mounted gantry cranes, also known as rail-mounted container gantry cranes, are lifting equipment used in ports for loading, unloading, handling, and stacking containers in container rail transfer yards and large container storage and transportation yards. A towing trolley, as a power supply method, is usually used in conjunction with mobile equipment (such as cranes and trolleys) for electrical or signal transmission. In rail-mounted gantry cranes, the towing trolley system generally requires an additional towing trolley to provide power or signals to the trolley portion of the rail-mounted gantry crane.

[0003] Replacing a rail-mounted gantry crane tow bar is a complex and meticulous process involving multiple steps and specialized operational skills. Before replacing the tow bar, the rail-mounted crane must be stopped and the power supply disconnected to prevent accidents during the replacement process. When installing the new tow bar, ensure it is accurately positioned, securely fixed, and fits well with other components. The entire replacement process is time-consuming, and the work area is at a considerable height, posing significant safety hazards for personnel working at height for extended periods.

[0004] The replacement of existing rail-mounted gantry crane cables requires multiple people to work continuously for more than ten days. There is no fixed replacement equipment or method, resulting in slow replacement efficiency, a large workload, and disruption to the normal operation of the port loading and unloading site. Utility Model Content

[0005] To address the problem of low efficiency in replacing track gantry crane tow hooks, this utility model provides a track gantry crane tow hook replacement device.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0007] A rail-mounted crane tow bar replacement device includes a rail detachably mounted on two opposing supports. One end of the rail is closed, and the other end is equipped with a connecting component. Two lifting lugs are provided on the top surface of the rail, symmetrically arranged about the center of gravity of the rail. In use, the tow bar is pre-installed on the rail. A crane uses the lifting lugs to lift the rail and the tow bar together to the rail-mounted crane where the tow bar needs to be replaced. The connecting component connects the rail to the tow bar slide rail of the rail-mounted crane, and the tow bar slides from the rail to the rail-mounted crane. This greatly reduces downtime for replacement and improves work efficiency.

[0008] Preferably, the track is constructed as an I-beam; a cover plate is fixedly installed at one end of the track; the connecting assembly includes a connecting plate; the connecting plate is welded onto the top surface of the track and extends to the outer side of the track; the connecting plate is located at the end away from the cover plate; the connecting plate has two through holes. The cover plate prevents the tow hook from coming off. The tow hook slide rail of the track crane can be threadedly connected by bolts passing through the through holes.

[0009] Preferably, two bolts are threaded between the connecting plate and the top surface of the track; a reinforcing plate is also welded between the end of the connecting plate and the top surface of the track. The bolts and reinforcing plate ensure the firmness of the connecting plate.

[0010] Preferably, the connecting plate has a U-shaped groove from the outside in. This facilitates the pre-installation of bolts on the rails of the rail-mounted crane, which are then secured in the U-shaped grooves, making it easy to connect the rails and the rail-mounted crane's slide rails when the crane lifts the rails.

[0011] Preferably, the bracket includes a base; a crossarm is movably mounted on the base; and a rail is detachably mounted on the crossarm. The crossarm is movably mounted on the base, and after a cable is pre-installed on the rail, the crossarm is raised to facilitate the installation of cables on the cable.

[0012] Preferably, the base includes an I-beam; a portal frame is fixedly mounted on the top surface of the I-beam; a crossbeam is inserted into the portal frame; and a linear drive mechanism is provided between the crossbeam and the portal frame.

[0013] Preferably, the linear drive mechanism includes a nut rotatably mounted on the U-shaped frame; a screw threaded onto the nut; the crossarm as a whole is arranged in an inverted U-shape; the two side rods of the crossarm are inserted into the U-shaped frame; and the upper end of the screw is fixedly mounted on the bottom rod of the crossarm. Rotating the nut drives the screw to rise and fall, thereby driving the crossarm to rise and fall.

[0014] Preferably, the base rod has a U-shaped cross-section; the screw is rotatably mounted on one side plate of the base rod; two limiting blocks are provided in the middle of the other side plate of the base rod; the two limiting blocks are spaced apart and parallel to each other; a pin hole is provided on the base rod; a second through hole is provided on the rail; a pin is provided in the second through hole. The rail can be fixed to the crossarm by passing the pin through the second through hole and the pin hole; the limiting blocks restrict the movement of the rail and facilitate the installation of the tow bar.

[0015] As can be seen from the above technical solutions, the advantages of this utility model are as follows: This solution provides a rail-mounted crane tow bar replacement device. In use, the tow bar is pre-installed on the rail. A crane uses lifting lugs to lift the rail together with the tow bar to the rail-mounted crane where the tow bar needs to be replaced. The connecting component is used to connect the rail with the tow bar slide rail of the rail-mounted crane. The tow bar is then slid from the rail to the rail-mounted crane, which greatly shortens the downtime for replacement and improves work efficiency. Attached Figure Description

[0023] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0024] like Figure 1 As shown, a track-mounted towing maneuvering device includes a track 1, which is detachably mounted on two opposing supports 2. One end of the track 1 is closed, and the other end is provided with a connecting component. Two lifting lugs 3 are provided on the top surface of the track 1. The two lifting lugs 3 are symmetrically arranged with the center of gravity of the track 1 as the center.

[0025] like Figure 2As shown, in the above configuration, the track 1 is constructed as an I-beam; a cover plate 101 is fixedly installed at one end of the track 1 to prevent the tow hook from coming off; the connecting assembly includes a connecting plate 4; the connecting plate 4 is welded onto the top surface of the track 1 and extends to the outside of the track 1; the connecting plate 4 is located at the end away from the cover plate 101; the connecting plate 4 has two through holes 401, which allow bolts to be threadedly connected to the tow hook rail of the rail crane through the through holes 401. Two bolts 5 are threaded between the connecting plate 4 and the top surface of the track 1; a reinforcing plate 6 is also welded between the end of the connecting plate 4 and the top surface of the track. The bolts 5 and the reinforcing plate 6 ensure the firmness of the connecting plate 4. A U-shaped groove 402 is provided on the connecting plate 4 from the outside inward, which facilitates the pre-installation of bolts on the rail crane's slide rail. When the crane lifts the track and docks with the rail crane's slide rail, the bolts are used to wedge into the U-shaped groove 402, reducing track sway and facilitating docking between the track and the rail crane's slide rail.

[0026] like Figure 3 As shown, the bracket 2 includes a base 201; the base 201 includes an I-beam 2011; a portal frame 2012 is fixedly mounted on the top surface of the I-beam 2011; a crossbeam 202 is inserted into the portal frame 2012; a linear drive mechanism is provided between the crossbeam 202 and the portal frame 2012. The linear drive mechanism includes a nut 203 rotatably mounted on the portal frame 2012; a screw 204 is threaded onto the nut 203; the length of the nut 203 is longer than the thickness of the portal frame 2012, and the nut 203 protrudes from the outer wall of the portal frame 2012 in a hexagonal shape, making it convenient to rotate the nut 203 with a wrench.

[0027] The crossarm 202 is shaped like an inverted U-shape. The two side rods 2021 of the crossarm 202 are inserted into the U-shaped frame 2012. The upper end of the screw 204 is fixed to the bottom rod 2022 of the crossarm 202. The bottom rod 2022 has a U-shaped cross-section. The screw 204 is rotatably mounted on one side plate of the bottom rod 2022. Two limiting blocks 2023 are located in the middle of the other side plate of the bottom rod 2022. The two limiting blocks 2023 are spaced apart and parallel to each other. A pin hole 2024 is provided on the bottom rod 2022. A through hole 102 is provided on the track 1. A pin 7 is installed inside the through hole 102. The pin 7 can pass through the through hole 102 and the pin hole 2024 to fix the track 1 to the crossarm 202. The limiting blocks 2023 restrict the movement of the track 1, facilitating the installation of the tow bar.

[0028] When installing the tow bar, place two brackets 2 on the ground beforehand, with the two brackets 2 arranged in parallel. Place the track 1 on the bracket 2; the track 1 is placed between the limiting blocks 2023 on the bracket 2, and the track 1 is fixed to the crossbeam 202 by using the pin 7 passing through the through hole 102 and the pin hole 2024;

[0029] At this time, the crossarm 202 is lowered on the base 201; then the cable tie is installed on the track 1. After the cable tie is installed, the nut 203 on the portal frame 2012 is rotated with a wrench, and the crossarm is raised by the screw 204 to make room for the cable connection on the cable tie.

[0030] Then, the crane hook is used to lift the rail 1 by holding the lifting lug 3 until the rail 1 is raised to the height of the rail crane's drag rail. Bolts are pre-threaded at the end of the rail crane's drag rail, and the U-shaped groove 402 of the connecting plate 4 is used to hold the bolts to limit the swaying of the rail 1. Then, the bolts are inserted into the through hole 401, and the bolts are threaded to connect the rail crane's drag rail, thus completing the connection between the rail 1 and the rail crane's drag rail. After that, the drag rail and cable on the rail 1 are slid into the rail crane's drag rail together.

[0031] When dismantling the tow bar of the rail-mounted crane, connect rail 1 to the rail-mounted crane's slide rail, slide the tow bar on the rail-mounted crane's slide rail into rail 1, then separate rail 1 from the rail-mounted crane's slide rail, and lift rail 1 and the tow bar down together for dismantling.

[0032] In use, two rails 1 and two cranes are used. One rail 1 has a tow bar and cable pre-installed on the support 2. The tow bar on the rail is removed using one crane and rail 1. The other crane is used to lift the rail 1 with the tow bar installed for replacement, reducing downtime and improving replacement efficiency.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
