Description

Technical Field

[0001] This utility model relates to the field of track replacement technology, specifically a rapid track replacement hoisting device for urban rail transit. Background Technology

[0002] Urban rail transit systems include subway systems, light rail systems, straddle-type monorail systems, etc. When the track needs to be replaced, a track replacement hoisting device is used.

[0003] In existing technologies, urban rail transit track replacement operations are mainly completed using lifting devices based on beam structures. This device achieves track assembly and disassembly by symmetrically setting T-shaped support rods on both sides of the bottom of the beam, combined with a laterally movable hand-cranked hoist and track clamps installed on the beam. While suitable for confined working environments and easy to assemble, in actual use, because the track needs to be fixed to the top of the sleepers, the lifting device must be simultaneously positioned above the sleepers for operation. This prevents the installation of wheels at the bottom, making short-distance transport of the lifting device before and after construction inconvenient. Typically, the beam, support rods, and hoist must be disassembled one by one, requiring multiple workers to collaboratively move the disassembled components, significantly increasing labor and time costs. Therefore, an improved rapid track replacement lifting device for urban rail transit is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a rapid track-changing hoisting device for urban rail transit, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid rail replacement hoisting device for urban rail transit, comprising a base plate, a support rod fixedly installed on the top of the base plate, a reinforcing rod fixedly installed on the top of the base plate, the reinforcing rod being fixedly installed with the support rod, a positioning hole being provided inside the support rod, a crossbeam being slidably installed on the outside of the support rod, a hand-cranked hoist being provided on the top of the crossbeam, a moving mechanism being provided on the outside of the support rod, and a positioning mechanism being provided inside the support rod.

[0006] Preferably, the moving mechanism includes a positioning seat, which is fixedly installed on the outside of the support rod.

[0007] Preferably, the positioning seat has a through hole at the position corresponding to the insertion post, and the insertion post is slidably installed in the through hole to facilitate the movement of the insertion post.

[0008] Preferably, the positioning block has a groove at the position corresponding to the insertion post, and the insertion post is inserted into the groove to facilitate the positioning block's positioning function.

[0009] Preferably, the positioning mechanism includes a positioning column, which is slidably installed inside the positioning hole. A baffle is fixedly installed on the front of the positioning column, and the baffle is slidably installed with the support rod. A pull rod is fixedly installed on the front of the baffle.

[0010] Compared with the prior art, this utility model provides a rapid track-changing hoisting device for urban rail transit, which has the following beneficial effects:

[0011] 1. This urban rail transit rapid track changing hoisting device, through its set moving mechanism, facilitates the positioning of the positioning block through the set positioning seat during use. The rotating screw facilitates the movement of the sliding plate. With the cooperation of the insert column, it is easy to limit the positioning block after positioning. By tilting the device to one side, the two moving wheels contact the ground, which facilitates the short-distance transportation of the device without the need for disassembly and handling, thus reducing labor and time costs.

[0012] 2. This urban rail transit rapid rail replacement hoisting device, through its positioning mechanism, uses placement grooves and sponge pads to facilitate the storage and protection of the rail clamps after the device is tilted, preventing the rail clamps from contacting the ground. By sliding the positioning pin into the appropriate positioning hole, the baffle is easily limited by the cooperation of the stud and the threaded knob, thus facilitating the subsequent rapid positioning of the crossbeam.

[0021] Example 1:

[0022] Please see Figure 1-2 This utility model provides a technical solution: a rapid rail replacement hoisting device for urban rail transit, including a base plate 1, a support rod 2 fixedly installed on the top of the base plate 1, and two reinforcing rods 3 fixedly installed on the top of the base plate 1. The two reinforcing rods 3 are symmetrically installed on the top of the base plate 1 and fixedly installed with the support rod 2. The support rod 2 has positioning holes 4 inside, and a crossbeam 5 is slidably installed on the outside of the support rod 2. Multiple positioning holes 4 are equally spaced, and the center distance between adjacent positioning holes 4 is the same as the height of the crossbeam 5, which facilitates the equidistant installation of the crossbeam 5. A hand-cranked hoist 6 is set on the top of the crossbeam 5, and a rail clamp is connected to the bottom of the chain of the hand-cranked hoist 6 to facilitate the hoisting of the rail. A moving mechanism 7 is set on the outside of the support rod 2. There are two sets of moving mechanisms 7, which are respectively set on the top and bottom of the outside of the support rod 2 to facilitate the support and movement of the device. A positioning mechanism 8 is set inside the support rod 2.

[0023] Furthermore, the moving mechanism 7 includes a positioning seat 701, which is fixedly installed on the outside of the support rod 2. A connecting shell 702 is fixedly installed on the outside of the positioning seat 701. A screw 703 is threadedly installed inside the connecting shell 702. A sliding plate 704 is rotatably installed on the end of the screw 703 near the positioning seat 701. The sliding plate 704 is slidably installed on the inner wall of the connecting shell 702. A pin 705 is fixedly installed on the side of the sliding plate 704 away from the screw 703. A positioning block 706 is slidably installed on the inner wall of the positioning seat 701. A support leg 707 is fixedly installed on the end of the positioning block 706 away from the support rod 2. The support leg 707 is located away from the positioning block 706. One end of the device 06 is fixedly equipped with a movable wheel 708. The movable wheel 708 near the bottom of the support rod 2 is a directional wheel, and the movable wheel 708 near the top of the support rod 2 is a swivel wheel, which facilitates the movement of the device. The positioning seat 701 facilitates the positioning of the positioning block 706. The rotating screw 703 facilitates the movement of the sliding plate 704. With the cooperation of the insert 705, the positioning block 706 is limited after positioning. By tilting the device to one side, the two movable wheels 708 come into contact with the ground, which facilitates short-distance transportation of the device without disassembling and carrying it, thus reducing labor and time costs.

[0024] Furthermore, a through hole is provided inside the positioning base 701 at the position corresponding to the insertion post 705, and the insertion post 705 is slidably installed in the through hole, so that the insertion post 705 can move closer to or away from the positioning block 706.

[0025] Furthermore, a groove is provided inside the positioning block 706 at the position corresponding to the insertion post 705, and the insertion post 705 is inserted into the groove, which facilitates the positioning block 706 to limit the operation, thereby completing the positioning of the moving wheel 708.

[0026] Please see Figure 3-4Furthermore, in conjunction with Embodiment 1, the positioning mechanism 8 includes a positioning post 801, which is slidably installed inside the positioning hole 4. A baffle 802 is fixedly installed on the front of the positioning post 801, and the height of the baffle 802 is the same as the height of the crossbeam 5, so as to facilitate the quick positioning of the crossbeam 5 and to easily position the crossbeam 5 to a suitable height. The baffle 802 is slidably installed with the support rod 2. A pull rod 803 is fixedly installed on the front of the baffle 802. A stud 804 is fixedly installed on the back of the positioning post 801. The diameter of the stud 804 is slightly smaller than the diameter of the positioning post 801, so that the stud 804 can pass through the positioning hole 4. A threaded knob 805 is installed on the external thread of the stud 804. A bolt 806 is movably installed inside the crossbeam 5. The bolt 806 is installed inside the positioning hole 4. A nut is installed on the external thread of the bolt 806. A placement groove 807 is opened on the inner side of the support rod 2. A sponge pad 808 is placed inside the placement groove 807. The placement groove 807 and the sponge pad 808 facilitate the storage and protection of the track clamp after the device is tilted, preventing the track clamp from contacting the ground. By sliding the positioning pin 801 into the appropriate positioning hole 4, the baffle 802 is limited by the cooperation of the stud 804 and the threaded knob 805, which facilitates the subsequent quick positioning of the crossbeam 5. It also facilitates the contact between the crossbeam 5 and the baffle 802, making it easy to pass the bolt 806 through the positioning hole 4 and the crossbeam 5. With the cooperation of the nut, the crossbeam 5 is quickly installed and positioned.

[0027] In actual operation, when this device is used, by sliding the positioning block 706 onto the inner wall of the positioning seat 701, rotating the screw 703 causes the slide plate 704 to move. With the cooperation of the insert 705, the positioning block 706 is limited, completing the installation of the moving wheel 708. By sliding the positioning pin 801 into the appropriate positioning hole 4, with the cooperation of the screw 804 and the threaded knob 805, the positioning pin 801 and the baffle 802 are limited. By sliding the crossbeam 5 outside the support rod 2, the crossbeam 5 contacts the baffle 802, completing the installation of the crossbeam 5. The positioning work is carried out by passing the bolt 806 through the positioning hole 4 and the crossbeam 5, and limiting the crossbeam 5 with the cooperation of the nut. The hand-cranked hoist 6 is installed on the top of the crossbeam 5, and the rail clamp is connected to the bottom of the chain of the hand-cranked hoist 6 to carry out the disassembly and assembly of the rail. When the device needs to be transported over a short distance, the device is tilted to one side so that the moving wheel 708 contacts the ground, which facilitates the movement of the device. After tilting, the hand-cranked hoist 6 is moved. With the cooperation of the placement groove 807 and the sponge pad 808, the rail clamp is stored and protected.
