Description
Technical Field
[0001] This utility model relates to the field of subway construction wiring technology; specifically, this utility model relates to a wiring device for subway construction. Background Technology
[0002] Many cities in my country are now undertaking large-scale subway construction. Subways are a form of rail transport, referring to urban rail transit systems that primarily operate underground. Subway construction requires the use of a large number of cables, and the quality of cable laying directly affects subway safety. Subway cable laying equipment is generally used for cable installation, and the laying height varies depending on the type of cable.
[0003] Existing cable laying equipment can only move in a straight line when laying cables and place them on cable supports. Since the cable supports are manually installed on the tunnel wall, there are height errors between the cable supports. This makes it easy for the cable to hit the tip of the cable support during laying, causing the cable support to deform and affecting the quality of cable laying. Utility Model Content
[0004] In view of this, the present invention provides a wiring device for subway construction, thereby solving or at least alleviating the above-mentioned problems existing in the prior art.
[0005] To achieve the aforementioned objectives, this utility model provides a wiring device for subway construction, comprising:
[0006] The laying trolley can move inside the tunnel;
[0007] A cantilever, slidably mounted on a laying trolley, is used to control the release position of the cable;
[0008] The transport plate is fixedly installed at the end of the cantilever away from the laying trolley and can support the bottom of the cable, used to lay the cable on the cable support;
[0009] An adjustment structure is installed on the bottom surface of the transport plate to avoid installation errors of the cable brackets, enabling the transport plate to carry the cable over the cable brackets.
[0010] In the aforementioned wiring device for subway construction, optionally, the transport plate includes:
[0011] A connecting frame is fixedly installed at the end of the cantilever away from the laying trolley, and is used to fix the transport plate on the cantilever.
[0012] The tray is slidably mounted at the bottom of the connector in the height direction and can contact the bottom of the cable for supporting and transporting the cable;
[0013] The limiting sleeve is rotatably mounted on the support plate to restrict the cable and prevent it from detaching from the cable bracket.
[0014] A sliding sleeve is fixedly installed at the end of the pallet away from the limiting sleeve, so that the pallet can remain stable when sliding in the height direction.
[0015] In the aforementioned wiring device for subway construction, optionally, the connecting frame includes a threaded rod and a sliding rod respectively fixedly installed on both sides of its bottom end. The threaded rod is threadedly engaged with a limiting sleeve to control the distance between the support plate and the connecting frame in the height direction. The sliding rod is slidably engaged with the sliding sleeve to keep the support plate stable when it slides in the height direction.
[0016] In the aforementioned wiring device for subway construction, optionally, the adjustment structure includes:
[0017] The drive gear is fixedly installed at the bottom end of the limit sleeve and located on the bottom surface of the support plate, and is used to drive the limit sleeve to rotate.
[0018] The rack is slidably mounted on the bottom surface of the support plate and meshes with the drive gear to drive the drive gear to rotate;
[0019] A contact head is fixedly installed at the end of the rack away from the drive gear and parallel to the axis of the drive gear. The bottom end of the contact head is lower than the bottom surface of the tray in the height direction, so that the tray can completely pass over the cable bracket.
[0020] In the aforementioned wiring device for subway construction, the adjustment structure may optionally further include:
[0021] A sliding block is slidably mounted on the bottom surface of the pallet. The sliding block can contact the end of the rack away from the contact head to reset the pallet to its initial height.
[0022] The rotating rod is rotatably mounted on the bottom surface of the end of the pallet away from the drive gear. The two ends of the rotating rod contact the side of the sliding block and the inner wall of the tunnel, respectively, and are used to drive the sliding block to move to the position to reset the pallet.
[0023] In the aforementioned wiring device for subway construction, the adjustment structure may optionally further include:
[0024] The limiting plate is fixedly installed on the side of the support plate away from the sliding block and can contact the side of the rotating rod to limit the rotation direction of the rotating rod.
[0025] A spring is fixedly installed between the limiting plate and the sliding block. The spring is located below the rotating rod and is used to keep the limiting plate and the rotating rod in contact, so that the rotating rod can remain perpendicular to the support plate.
[0026] This utility model discloses a cabling device for subway construction, which uses a transport plate that can pass through the gaps in the cable supports. When the transport plate passes through the gaps in the cable supports, the cable at the end of the transport plate away from the direction of movement of the laying trolley will come into contact with the cable support due to its own weight, thus achieving the effect of cable laying. Furthermore, the transport plate is equipped with an adjustment structure, which can adapt to the errors between the cable supports when the transport plate moves, preventing the cable from colliding with the cable supports during laying and affecting the laying quality.

[0033] 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.
[0034] like Figures 1 to 4 As shown, a typical embodiment of this utility model provides a wiring device for subway construction, comprising:
[0035] The laying trolley 1 is capable of moving inside the tunnel;
[0036] Cantilever 2 is slidably mounted on laying trolley 1 and is used to control the release position of the cable;
[0037] The transport plate 3 is fixedly installed at the end of the cantilever 2 away from the laying trolley 1 and can support the bottom of the cable for laying the cable on the cable support.
[0038] Adjustment structure 4 is set on the bottom surface of transport plate 3 to avoid installation errors of cable brackets, so that transport plate 3 can drive the cable over the cable bracket.
[0039] To achieve the effect that the transport plate 3 can pass through the gaps in the cable supports when it can carry the cable for laying, the cantilever 2 includes a support frame 2-1 fixedly installed on the laying trolley 1 and a movable frame 2-2 that can be slidably installed laterally and longitudinally on the support frame 2-1. The end of the transport plate 3 is fixedly connected to the movable frame 2-2. The lateral position of the movable frame 2-2 on the support frame 2-1 is controlled to control the lateral distance between the transport plate 3 and the cable support. The longitudinal position of the movable frame 2-2 on the support frame 2-1 is controlled to control the longitudinal distance between the transport plate 3 and the cable support. This allows the transport plate 3 to be adjusted to a suitable height and to pass through the gaps in the cable support to lay the cable.
[0040] To avoid errors during cable bracket installation that could cause the transport plate 3 to collide with the cable bracket during cable laying, an adjustment structure 4 is installed on the bottom surface of the transport plate 3. When the transport plate 3 moves, if the adjustment structure 4 comes into contact with the cable bracket, it can adjust the height of the cable so that it can pass over the cable bracket. If the adjustment structure 4 does not come into contact with the cable bracket, it means that the cable can pass through the gap in the cable bracket, which is convenient for cable laying.
[0041] Transport plate 3 includes:
[0042] The connecting frame 3-1 is fixedly installed at the end of the cantilever 2 away from the laying trolley 1, and is used to fix the transport plate 3 on the cantilever 2.
[0043] The tray 3-2 is slidably disposed at the bottom of the connecting frame 3-1 in the height direction and can contact the bottom of the cable for carrying and transporting the cable;
[0044] The limiting sleeve 3-3 is rotatably mounted on the support plate 3-2 to limit the cable and prevent it from detaching from the cable bracket;
[0045] The sliding sleeve 3-4 is fixedly installed at the end of the pallet 3-2 away from the limiting sleeve 3-3, so that the pallet 3-2 can remain stable when sliding in the height direction.
[0046] To enable the cable to pass over the cable support in the height direction, the cable is placed on the top surface of the tray 3-2. When the laying trolley 1 moves, it can drive the tray 3-2 to move as well. At this time, when the cable is released, it will contact the limiting sleeve 3-3 to prevent the cable from detaching from the tray 3-2. When the height of the tray 3-2 is higher than the cable support, the cable can pass smoothly through the gap of the cable support, which is convenient for laying the cable. When the height of the tray 3-2 is lower than the cable support, the tray 3-2 moves upward in the height direction of the connecting frame 3-1 so that it can pass over the cable support, which is convenient for laying the cable.
[0047] The connecting frame 3-1 includes a threaded rod 3-5 and a sliding rod 3-6, which are respectively fixedly installed on both sides of its bottom end. The threaded rod 3-5 is threadedly engaged with the limiting sleeve 3-3 to control the distance between the support plate 3-2 and the connecting frame 3-1 in the height direction. The sliding rod 3-6 is slidably engaged with the sliding sleeve 3-4 to ensure that the support plate 3-2 can remain stable when sliding in the height direction.
[0048] To enable the pallet 3-2 to move in the height direction of the connecting frame 3-1, the connecting frame 3-1 includes a threaded rod 3-5 and a sliding rod 3-6, which are respectively fixedly installed on both sides of its bottom end. The threaded rod 3-5 is threadedly engaged with the limiting sleeve 3-3, and the sliding rod 3-6 is slidably engaged with the sliding sleeve 3-4. When the limiting sleeve 3-3 rotates, it can move axially in the threaded rod 3-5, which facilitates the movement of the pallet 3-2 in the height direction of the connecting frame 3-1. At this time, the sliding sleeve 3-4 is restricted by the sliding rod 3-6, so that the pallet 3-2 remains stable when moving in the height direction of the bracket, making the cable laying more stable.
[0049] Adjustment structure 4 includes:
[0050] The drive gear 4-1 is fixedly installed at the bottom end of the limiting sleeve 3-3 and located on the bottom surface of the support plate 3-2, and is used to drive the limiting sleeve 3-3 to rotate.
[0051] The rack 4-2 is slidably mounted on the bottom surface of the support plate 3-2 and meshes with the drive gear 4-1 to drive the drive gear 4-1 to rotate;
[0052] The contact head 4-3 is fixedly installed at the end of the rack 4-2 away from the drive gear 4-1 and parallel to the axis of the drive gear 4-1. The bottom end of the contact head 4-3 is lower than the bottom surface of the support plate 3-2 in the height direction, so that the support plate 3-2 can completely pass over the cable bracket.
[0053] To achieve the effect of allowing the limiting sleeve 3-3 to rotate, when the pallet 3-2 moves, the contact head 4-3 first approaches the cable bracket. When the contact head 4-3 is not in contact with the cable bracket, it means that the pallet 3-2 is higher than the cable bracket, which facilitates cable laying. When the contact head 4-3 contacts the cable bracket, it is blocked by the cable bracket. At this time, the pallet 3-2 continues to move, allowing the rack 4-2 to move relative to the pallet 3-2 and towards the sliding sleeve 3-4. The rack 4-2 drives the drive gear 4-1 to rotate. When the drive gear 4-1 rotates, it drives the limiting sleeve 3-3 to rotate, allowing the limiting sleeve 3-3 to drive the pallet 3-2 to move in the height direction of the connecting frame 3-1. If the bottom end of the contact head 4-3 can pass over the cable bracket, the rack 4-2 will not continue to move, indicating that the pallet 3-2 is higher than the cable bracket at this time, allowing the pallet 3-2 to pass over the cable bracket.
[0054] Adjustment structure 4 also includes:
[0055] The sliding block 4-4 is slidably mounted on the bottom surface of the pallet 3-2. The sliding block 4-4 can contact the end of the rack 4-2 away from the contact head 4-3, and is used to reset the pallet 3-2 to its initial height.
[0056] Rotating rod 4-5 is rotatably mounted on the bottom surface of the end of the pallet 3-2 away from the drive gear 4-1. The two ends of rotating rod 4-5 contact the side of sliding block 4-4 and the inner wall of the tunnel, respectively, and are used to drive sliding block 4-4 to move to the position to reset pallet 3-2.
[0057] To ensure that the pallet 3-2 returns to its original position after passing the cable support, preventing the accumulation of errors during subsequent use, a movable wheel is rotatably mounted on one end of the rotating rod 4-5. The movable wheel contacts the inner wall of the tunnel, allowing the rotating rod 4-5 to contact the root of the cable support. When the rotating rod 4-5 contacts the root of the cable support, one end of the rotating rod 4-5 is blocked by the root of the cable support, allowing the other end of the rotating rod 4-5 to rotate toward the drive gear 4-1. This drives the sliding block 4-4 to move toward the rack 4-2. When the rotating rod 4-5 passes the cable support, the end of the rotating rod 4-5 moves the sliding block 4-4 to its furthest position, pushing the rack 4-2 back to its initial position, thus restoring the pallet 3-2 to its initial position for subsequent use.
[0058] Adjustment structure 4 also includes:
[0059] The limiting plate 4-6 is fixedly installed on the side of the support plate 3-2 away from the sliding block 4-4, and can contact the side of the rotating rod 4-5 to limit the rotation direction of the rotating rod 4-5;
[0060] Spring 4-7 is fixedly installed between the limiting plate 4-6 and the sliding block 4-4. Spring 4-7 is located below the rotating rod 4-5 and is used to keep the limiting plate 4-6 and the rotating rod 4-5 in contact, so that the rotating rod 4-5 can remain perpendicular to the support plate 3-2.
[0061] To ensure that the rotating rod 4-5 returns to its original position after passing the cable bracket for easy use next time, the spring 4-7 resets after the rotating plate passes the cable bracket. This allows the sliding block 4-4 to move toward the rotating rod 4-5 and elastically clamps the rotating plate between the limiting plate 4-6 and the sliding block 4-4, allowing the rotating rod 4-5 to reset and remain perpendicular to the support plate 3-2 for easy use next time.
[0062] 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.
