Description

Technical Field

[0001] This utility model relates to the field of rail transit construction technology, and in particular to a ground line protection device for urban rail transit construction. Background Technology

[0002] The ground line protection device for urban rail transit construction is a device specifically designed to protect the safety of the ground line during urban rail transit construction. It mainly protects the ground line inside the device to prevent damage from external forces and ensures the integrity and safety of the line during construction and after operation.

[0003] However, since the lengths of ground lines vary, most of the existing urban rail transit construction ground line protection devices on the market are not convenient for workers to assemble and expand, and are difficult to adjust flexibly according to changes in the length of the protected line, which reduces the flexibility and adaptability of the protection devices.

[0004] Therefore, those skilled in the art have provided a ground track protection device for urban rail transit construction to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a ground line protection device for urban rail transit construction. The device connects the inclined blocks by sliding the first connecting groove and the first connecting block, and the second connecting groove and the second connecting block in the connecting mechanism. The second return spring inside the slot acts on the inclined block to keep the inclined block and the second connecting block in a locked state, which facilitates assembly and expansion.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A protective device for ground tracks during urban rail transit construction includes a protective shell, an opening and closing mechanism, and a connecting mechanism. Inclined blocks are fixedly connected to the outer walls of both the front and rear ends of the protective shell. The opening and closing mechanism, comprising two pull rods, is located at the upper end of the protective shell. Mounting holes are provided on both sides of the upper end of the inclined blocks, away from the center of the protective shell. The connecting mechanism, comprising two moving blocks, is located at both the front and rear ends of the protective shell. A first connecting groove is provided on the outer wall of one side of the inclined block, near the center of the protective shell. The connecting groove is located on the outer wall of one side of the inclined block, away from the center of the protective shell. A second connecting groove is provided on one side of the center of the protective shell. A first connecting block is fixedly connected to the outer wall of the other side of the inclined block near the center of the protective shell. A second connecting block is fixedly connected to the outer wall of the other side of the inclined block away from the center of the protective shell. A slot is provided on both sides inside the inclined block. A second return spring is fixedly connected to the inner wall of the slot near the center of the inclined block. An inclined block is fixedly connected to the second return spring near the center of the inclined block. The inclined block is fixedly connected to the moving block on the side near the center of the inclined block.

[0008] Through the above technical solution, the two inclined blocks are connected by sliding connection between the first connecting groove and the first connecting block, and between the second connecting groove and the second connecting block in the connecting mechanism. With the second return spring inside the slot acting on the inclined block, the inclined block and the second connecting block are engaged and connected for reinforcement, thereby facilitating assembly and expansion.

[0009] Furthermore, the front ends of both sides of the upper end of the protective shell are provided with sliding grooves, and the inner walls of the front ends of the sliding grooves are fixedly connected with first return springs. The rear ends of the first return springs are fixedly connected with protrusions, and the center of the outer wall of the front end of the protrusions is fixedly connected with a pull rod.

[0010] Through the above technical solution, the first reset spring inside the slide groove in the opening and closing mechanism acts on the protrusion, so that the protrusion can maintain the latched state with the cover plate that is hinged to the protective shell. The pull rod can drive the protrusion to move, release the latched state of the cover plate, and thus facilitate the staff to open and close the cover plate for the placement of ground wiring.

[0011] Furthermore, a wiring groove is provided in the middle of the upper end of the protective shell, and a cover plate is hinged to the rear end of the upper end of the protective shell.

[0012] The above technical solution allows workers to place ground wiring inside the protective casing by creating wiring channels inside the casing, and a cover plate is hinged to the casing to seal it, thus protecting the internal ground wiring.

[0013] Furthermore, each of the mounting holes is equipped with a ground nail, and the first connecting block is slidably connected to the first connecting groove;

[0014] By driving the ground nails installed in the mounting holes into the ground, the protective device can be fixed to the ground and will not easily loosen. By using the first connecting block to slide with the first connecting groove, the inclined blocks on the two devices can be connected together, and the auxiliary devices can be connected to each other, which facilitates the extension of the length.

[0015] Furthermore, the second connecting blocks are all slidably connected to the second connecting groove, and the side of the inclined block away from the center of the inclined block passes through the inclined block and is engaged with the second connecting block.

[0016] Through the above technical solution, the second connecting blocks are slidably connected to the second connecting groove, so that the inclined blocks can be connected more tightly. The second return spring acts on the inclined block, so that the inclined block is engaged with the second connecting block, thereby reinforcing the inclined blocks.

[0017] Furthermore, all the inclined blocks slide inside the slots, and the side of the moving block near the center of the inclined block penetrates the slot into the interior of the mounting hole;

[0018] Through the above technical solution, by allowing the movable block fixedly connected to the inclined block to pass through the slot into the installation hole, the operator can pull the movable block to move the inclined block, release the locking connection of the second connecting block, and thus separate the inclined blocks.

[0019] Furthermore, the front ends of the protrusions all penetrate the protective shell and are snapped together with the cover plate, and the protrusions all slide inside the groove;

[0020] With the above technical solution, the first reset spring acts on the protrusion, so that the protrusion can maintain the latched state with the cover plate that is hinged to the protective shell, so that the cover plate will not be easily opened, thus better protecting the internal ground wiring. Pulling the lever can drive the protrusion to move inside the slide groove, release the latched state of the cover plate, and then open the cover plate.

[0021] Furthermore, the front ends of the pull rods all penetrate through the slide groove to the outside of the protective shell, and the upper end of the inclined block is provided with clearance openings on both sides near the center of the protective shell;

[0022] The above technical solution allows the pull rod to pass through the slide groove to the outside of the protective shell, and two clearance openings are made on the inclined block, so that the staff can reach into the clearance openings to pull the pull rod and release the protrusion from the cover plate.

[0023] This utility model has the following beneficial effects:

[0024] 1. The present invention proposes a ground line protection device for urban rail transit construction. By sliding the first connecting groove and the first connecting block and the second connecting groove and the second connecting block in the connecting mechanism, two inclined blocks are connected together. With the help of the second return spring inside the slot acting on the inclined block, the inclined block and the second connecting block are locked together for reinforcement. This makes it easier for workers to assemble and expand the device according to the changes in the length of the protected line, thus improving the flexibility and adaptability of the protection device.

[0025] 2. The present invention proposes a ground line protection device for urban rail transit construction. The first return spring inside the slide groove of the opening and closing mechanism acts on the protrusion, so that the protrusion can maintain the latching state with the cover plate that is hinged to the protective shell. The pull rod can drive the protrusion to move, release the latching state of the cover plate, and then facilitate the workers to open and close the cover plate for ground line placement, thus improving the convenience of operation.

[0036] A wiring groove 2 is provided in the middle of the upper end of the protective shell 1. A cover plate 401 is hinged to the rear end of the upper end of the protective shell 1. The wiring groove 2 inside the protective shell 1 allows workers to place the ground wiring inside the protective shell 1. The cover plate 401 hinged to the protective shell 1 closes the protective shell 1 and protects the ground wiring inside. Ground nails 6 are provided inside the mounting holes 5. The first connecting blocks 703 are slidably connected to the first connecting grooves 701. By driving the ground nails 6 in the mounting holes 5 into the ground, the protective device can be fixed to the ground and will not easily loosen. The sliding connection of the first connecting blocks 703 to the first connecting grooves 701 allows the inclined blocks 3 on the two devices to be connected together, facilitating the connection between auxiliary devices and the extension of length. The second connecting blocks 704 are slidably connected to the second connecting grooves 702. The inclined block 707 is away from the ground. One side of the inclined block 3 at its center penetrates the inclined block 3 and is snapped into the second connecting block 704. The second connecting block 704 is slidably connected to the second connecting groove 702, making the inclined blocks 3 more tightly connected. The second return spring 706 acts on the inclined block 707, making the inclined block 707 snap into the second connecting block 704, thus reinforcing the inclined blocks 3. The inclined block 707 slides inside the groove 705. The side of the moving block 708 near the center of the inclined block 3 penetrates the groove 705 into the mounting hole 5. By having the moving block 708 fixedly connected to the inclined block 707 penetrate the groove 705 into the mounting hole 5, the operator can pull the moving block 708 to move the inclined block 707, releasing the snap-fit ​​connection to the second connecting block 704, thereby allowing the inclined blocks 3 to separate.

[0037] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 The upper sides of the protective shell 1 are provided with sliding grooves 402. The inner wall of the front end of the sliding groove 402 is fixedly connected with a first return spring 403. The rear end of the first return spring 403 is fixedly connected with a protrusion 404. The center of the outer wall of the front end of the protrusion 404 is fixedly connected with a pull rod 405.

[0038] The front ends of the protrusions 404 all penetrate the protective shell 1 and are snapped into the cover plate 401. The protrusions 404 slide inside the slide groove 402. The first return spring 403 acts on the protrusions 404, so that the protrusions 404 can maintain the snapped state with the cover plate 401 which is hinged to the protective shell 1, so that the cover plate 401 will not be easily opened, thus better protecting the internal ground wiring. Pulling the pull rod 405 can drive the protrusions 404 to move inside the slide groove 402, releasing the cover plate 401. The cover plate 401 is opened when the 01 is engaged. The front end of the pull rod 405 passes through the slide groove 402 to the outside of the protective shell 1. The upper end of the inclined block 3 is provided with clearance openings 406 on both sides near the center of the protective shell 1. By allowing the pull rod 405 to pass through the slide groove 402 to the outside of the protective shell 1 and by providing two clearance openings 406 on the inclined block 3, the operator can reach into the clearance openings 406 to pull the pull rod 405 and release the engagement connection between the protrusion 404 and the cover plate 401.

[0039] Working principle: When using this urban rail transit construction ground line protection device, the worker first places the device on the ground. Based on the length of the protected ground line, multiple inclined blocks 3 are connected by sliding connections between the first connecting groove 701 and the first connecting block 703, and between the second connecting groove 702 and the second connecting block 704. The second return spring 706 inside the slot 705 acts on the inclined block 707, causing the inclined block 707 to engage with the second connecting block 704 for assembly and expansion. Then, during expansion, the worker inserts the device into the mounting hole 5... The ground nail 6 is driven into the ground to fix the device to the ground. Then, the staff pulls the lever 405, which moves the protrusion 404 to release the locking state of the cover plate 401, open the cover plate 401, and put the ground wire into the wiring groove 2 in the protective shell 1. Then the cover plate 401 is closed. Finally, if the staff needs to remove the device, they can pull the moving block 708 to move the inclined plate block 707 to release the locking state of the second connecting block 704, so that the inclined plate block 3 separates. The staff can then remove the device along the first connecting groove 701 and the second connecting groove 702.
