Abstract
Description
Technical Field
[0001] This utility model relates to the field of subway power equipment hoisting technology; specifically, this utility model relates to a subway power supply construction hoisting device. Background Technology
[0002] With the development of society, people are increasingly developing and utilizing underground space. As a means of transportation, the subway plays a very important role in modern society. In the construction of subways, the installation of electrical equipment is mainly carried out underground, which causes certain inconvenience to the transfer of electrical equipment. In particular, the ground space of the subway is limited, and commonly used cranes cannot be effectively operated inside the subway. Therefore, the transfer of electrical equipment in the construction of subway power supply needs to be carried out in conjunction with specific transfer equipment.
[0003] A search revealed Chinese Patent Publication No. CN218371328U, which discloses a hoisting device for subway construction. The device includes a base, a slide rail, a sliding block slidably connected to the bottom of the slide rail, a hoisting rope wound inside the sliding block, a transport box fixedly connected to the bottom of the hoisting rope, damping telescopic rods fixedly connected to both sides of the transport box, damping hinge seats fixedly connected to both sides of the sliding block, and a connecting shaft fixedly connected to one side of the damping hinge seat. One end of each of the two damping telescopic rods is fixedly connected to one end of the connecting shaft. The hoisting rope and sliding block enable horizontal transport of the transport box, improving work efficiency during construction. The damping hinge seats prevent the transport box from tilting due to air resistance during horizontal transport, thus preventing items inside from falling from a height and injuring workers below. This improves stability and safety. Furthermore, the slide rail is flexible in its installation location and easy to install.
[0004] In the above technical solutions, the transport box connected by the hoisting rope is prone to shaking during the transfer of the hoisted equipment, which poses a significant safety hazard. Especially when dealing with heavy power equipment such as large transformers, it is difficult to guarantee the safety of hoisting and transfer. Utility Model Content
[0005] In view of this, the present invention provides a hoisting device for subway power supply construction, thereby solving or at least alleviating the above-mentioned problems existing in the prior art.
[0006] To achieve the aforementioned objective, this utility model provides a subway power supply construction hoisting device, including a gantry frame, track wheels arranged on both sides of the bottom end of the gantry frame, and a crane arranged on the top of the gantry frame. Lifting seats are provided on both sides of the gantry frame, and a first lifting plate and a second lifting plate are respectively fixedly arranged on the two lifting seats. Multiple steel wire ropes are installed on the first lifting plate at intervals, and the other end of the steel wire ropes can be connected to the second lifting plate.
[0007] In the aforementioned subway power supply construction hoisting device, optionally, a plurality of winding wheels are rotatably installed on the first lifting plate at intervals, the winding wheels are distributed one-to-one with the wire rope, and one end of the wire rope is fixed to the winding wheel. The winding wheel winds or releases the wire rope by rotating forward or backward.
[0008] In the aforementioned subway power supply construction hoisting device, optionally, all the wire ropes located on one side of the lifting platform are fixedly connected to a connecting plate at the end away from the winding wheel. The connecting plate is provided with a hook, and the second lifting plate is provided with a hanging hole for the hook to be inserted from top to bottom.
[0009] In the aforementioned subway power supply construction hoisting device, optionally, all the wire ropes located on one side of the lifting seat are provided with pads on both sides of the bottom of the hoisted object.
[0010] In the aforementioned subway power supply construction hoisting device, optionally, a guide wheel assembly is provided at the bottom of the pad for each wire rope. The guide wheel assembly includes a wheel plate, a central guide wheel, and lateral guide wheels. The top of the wheel plate is fixedly connected to the pad. Two wheel plates are provided and are located on both sides of the wire rope. The two ends of the central guide wheel and the lateral guide wheels are rotatably engaged with the two wheel plates. One lateral guide wheel is provided on each side of the central guide wheel. The two lateral guide wheels are supported at the bottom of the wire rope, and the central guide wheel is supported at the top of the wire rope.
[0011] In the aforementioned subway power supply construction hoisting device, optionally, a support plate is provided at the bottom of the wheel plate, and the support plate fixes the bottoms of all wheel plates located at the bottom of the same pad as one piece.
[0012] This utility model relates to a subway power supply construction hoisting device. By setting steel wire ropes to support the bottom of the hoisted equipment, it can reduce the swaying of the hoisted equipment and improve the stability and safety of hoisting power equipment. The effect is particularly prominent when the gantry moves on the track to transfer power equipment.
[0013] This utility model discloses a subway power supply construction hoisting device. It uses steel wire ropes to support the bottom of the hoisted equipment. Utilizing the flexibility of the steel wire ropes, it can adapt to supporting power equipment of varying widths. Furthermore, when supporting the power equipment, the portions of the steel wire ropes on both sides bend upwards, leveraging the ropes' resilience to stabilize the equipment in both forward / backward and lateral directions, thus improving hoisting stability.
[0014] This novel and practical subway power supply construction hoisting device uses steel wire ropes to support the bottom of the hoisted equipment. By utilizing the flexibility of the steel wire ropes, the hoisting area in the middle of the gantry can be fully opened up in the initial state by retracting the steel wire ropes, making hoisting operations easier.

Detailed Implementation
[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] like Figures 1 to 5As shown, this utility model provides a subway power supply construction hoisting device, including a gantry frame 1, track wheels 2 set on both sides of the bottom end of the gantry frame 1, and a crane 3 set on the top of the gantry frame 1. Lifting seats 16 are provided on both sides of the gantry frame. A first lifting plate 4 and a second lifting plate 5 are respectively fixed on the two lifting seats 16. Multiple steel wire ropes 6 are installed on the first lifting plate 4 at intervals, and the other end of the steel wire ropes 6 can be connected to the second lifting plate 5.
[0024] During the hoisting process, the crane 3 lifts the equipment into the air, and then the wire rope 6 is connected to the second lifting plate 5. At this point, the first lifting plate 4, the wire rope 6, and the second lifting plate 5 form an effective support surface at the bottom of the hoisted equipment. Afterward, the two lifting seats 16 move upward, allowing the wire rope 6 to support the bottom of the hoisted equipment. The support of the wire rope 6 at the bottom of the hoisted equipment improves its stability, especially reducing equipment sway and enhancing safety as the gantry moves along the track.
[0025] When lowering the hoisted equipment, the lifting platform 16 and the hook descend synchronously. Before the equipment touches the ground, the wire rope 6 is separated from the second lifting plate 5, thus lowering the equipment.
[0026] Specifically, in this embodiment, a plurality of winding wheels 7 are rotatably mounted on the first lifting plate 4 at intervals. The winding wheels 7 are distributed one-to-one with the wire ropes 6, and one end of the wire rope 6 is fixed to the winding wheel 7. The winding wheels 7 wind or release the wire rope 6 by rotating clockwise or counterclockwise. In this embodiment, all the winding wheels 7 on the first lifting plate 4 are connected to a common shaft, so that all the winding wheels rotate synchronously and maintain the same tension in each wire rope 6.
[0027] By setting up the winding wheel 7, the wire rope 6 can be wound around it in the initial state, achieving the effect of effectively storing the wire rope 6. At the same time, it does not occupy the middle area of the gantry, providing sufficient space for the hoisting equipment.
[0028] All the wire ropes 6 located on one side of the lifting platform 16, away from the winding wheel 7, are fixedly connected to a connecting plate 8. The connecting plate 8 is equipped with hooks 9, and the second lifting plate 5 has hanging holes 10 for inserting the hooks 9 from top to bottom. All the wire ropes 6 located on one side of the lifting platform 16 are connected using the connecting plate 8. When connecting the wire ropes 6 to the second lifting plate 5, simply pull the connecting plate 8 to one side of the second lifting plate 5, and then insert the hooks 9 from top to bottom into the hanging holes 10. When the wire ropes 6 are supported at the bottom of the suspended equipment, the wire ropes 6 are subjected to equipment pressure, and the hooks 9 will be inserted into the hanging holes 10 more stably.
[0029] Furthermore, all the wire ropes 6 located on one side of the lifting platform 16 are provided with pads 11 for supporting the bottom sides of the suspended object. To improve the stability of the wire ropes 6 supporting the suspended equipment and to prevent the wire ropes 6 from rubbing against the suspended equipment, after connecting the connecting plate 8 to the second lifting plate 5, the pads 11 are moved on the wire ropes 6 according to the orientation of the bottom ends of the suspended equipment, so that the two pads 11 are located on opposite sides of the bottom of the suspended equipment. When the wire ropes 6 support the suspended equipment, the pads 11 support the bottom of the suspended equipment, thus preventing the wire ropes 6 from directly contacting the suspended equipment and avoiding damage to its surface. At the same time, the pads 11 connect all the wire ropes 6 located on the same side of the lifting plate into a single unit, providing a more stable support effect for the suspended equipment.
[0030] Specifically, the bottom of the pad 11 is provided with a guide wheel assembly for each wire rope 6. The guide wheel assembly includes a wheel plate 12, a middle guide wheel 13 and a side guide wheel 14. The top of the wheel plate 12 is fixed to the pad 11. There are two wheel plates 12, which are located on both sides of the wire rope 6 respectively. The two ends of the middle guide wheel 13 and the side guide wheel 14 are rotatably engaged with the two wheel plates 12. There is one side guide wheel 14 on each side of the middle guide wheel 13. The two side guide wheels 14 are supported on the bottom of the wire rope 6 respectively, and the middle guide wheel 13 is supported on the top of the wire rope 6.
[0031] By combining the central guide wheel 13 and the two lateral guide wheels 14, the pad 11 becomes more stable and less prone to deflection on the wire rope 6, further improving the stability of the support for the suspended equipment. At the same time, it makes the movement of the pad 11 on the wire rope 6 more flexible and convenient.
[0032] More specifically, a support plate 15 is provided at the bottom of the wheel plate 12, and the support plate 15 fixes the bottoms of all the wheel plates 12 located at the bottom of the same pad 11 into one piece. By setting the support plate 15, when lowering the hoisted equipment, the wire rope 6 can be directly lowered to the lowest position using the lifting seat 16, so that the support plate 15 lands on the ground, and the hoisted equipment is supported by the support plate 15. During the process of lowering the hoisted equipment, there is no need to separate the wire rope 6 from the second lifting plate 5 separately, which makes the operation more convenient. At the same time, throughout the entire process of lowering, the wire rope 6 can stably support the hoisted equipment and prevent it from swaying and hitting the ground.
[0033] The lifting seat 16 is internally threaded with a lead screw, both ends of which are rotatably mounted on the gantry, and the bottom end of the lead screw is connected to a rotary motor that controls its forward and reverse rotation.
[0034] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
