Description

Technical Field

[0001] This utility model relates to the field of cable laying, and in particular to a cable laying device for building electromechanical installation. Background Technology

[0002] Building electromechanical installation refers to an engineering field in building construction that is responsible for the installation, commissioning, and maintenance of various electromechanical equipment and systems within a building. These electromechanical equipment and systems include, but are not limited to, electrical equipment, lighting equipment, water supply and drainage systems, heating, ventilation and air conditioning systems, fire protection equipment, elevators, and power transmission and distribution facilities.

[0003] A search revealed a Chinese patent publication number CN222029575U, which discloses a cable laying device for building electromechanical installation. This patent includes a base plate and a cable management mechanism. A detachable cable placement mechanism and a stabilizing mechanism are provided on the top of the base plate. The detachable cable placement mechanism includes a mounting frame, inside which a winding roller is placed. The device works by pulling the clamp to the left, causing the slider to move to the left and compressing the spring. The clamp moves to the left until the roller can be removed from the mounting frame. The rollers at both ends of the winding roller, which is wound with cable, are placed in the placement slots on the mounting frame. Then, the clamp is released, and under the elastic force of the spring, the clamp moves to the right until it fits against the mounting frame, allowing for cable replacement. However, current cable laying devices for building electromechanical installation require pulling out the same length of cable each time for laying. In actual operation, this is often done by visual estimation, which has a large error. Furthermore, existing cable laying devices that can lay a fixed length of cable each time are often complex to operate, inconvenient to use, and difficult to adjust the laying length.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figure 1 — Figure 6 As shown, a cable laying device for building electromechanical installation includes a movable base 101, with casters 102 mounted on the bottom of the movable base 101. A rotating mechanism is provided on the movable base 101, including a winding wheel 201. Fixed plates 103 are bolted to both sides of the movable base 101, and limit mechanisms are provided on the fixed plates 103. Rotating shafts 202 are bolted to both ends of the winding wheel 201, and the rotating shafts 202 are rotatably connected within the movable base 101. A locking mechanism is provided on the movable base 101, including a mounting box 401 bolted to one side of the movable base 101. A movable frame 402 is movably mounted on the mounting box 401, and guide blocks 404 are bolted to the movable frame 402. The mounting box 401 has a guide groove 405, and the guide block 404 is slidably connected in the guide groove 405. The moving frame 402 is bolted to the insertion rod 403, and the rotating shaft 202 is bolted to the locking disc 205. The locking disc 205 is provided with several ring-shaped locking holes 206. The moving seat 101 has a through hole on one side for the insertion rod 403 to pass through. The locking holes 206 are the same size as the insertion rod 403 and are located at the corresponding positions of the insertion rod 403. The insertion rod 403 cooperates with the locking disc 205 to automatically lock when the winding wheel 201 rotates a certain number of times. The mounting box 401 is movably provided with an adjustment mechanism, which is used to adjust the number of rotations of the winding wheel 201 each time the cable is laid.

[0026] In this embodiment, the adjustment mechanism includes an operating rod 501, which is sleeved within the movable frame 402. A connecting plate 502 is bolted to the operating rod 501, and an elastic telescopic rod 504 is rotatably connected to the connecting plate 502. The elastic telescopic rod 504 is configured with two relatively sliding shafts interlocked, and a spring is installed inside the larger shaft. This is a conventional technical solution. One end of a rotating shaft 202 is bolted to a screw 204, and the end of the elastic telescopic rod 504 away from the connecting plate 502 is bolted to a mating block 505. The mating block 505 mates with the screw 204, and the surface of the mating block 505 opposite to the screw 204 has the same threaded groove as the screw 204. During the laying operation, the elastic telescopic rod 504 expands and contracts. When rod 504 is compressed, the pressure of elastic telescopic rod 504 is transmitted to mating block 505, causing mating block 505 to form a threaded engagement with screw 204. When winding wheel 201 rotates to release the wire, winding wheel 201 drives screw 204 to rotate through shaft 202. Screw 204 drives mating block 505 to move. Mating block 505 drives connecting plate 502 and operating rod 501 to move towards winding wheel 201 through elastic telescopic rod 504. Operating rod 501 drives moving frame 402 and insertion rod 403 to move towards locking disc 205 until insertion rod 403 reaches the position of locking disc 205 through through hole on moving seat 101. Insertion rod 403 will be inserted into locking hole 206 to lock the rotation of winding wheel 201.

[0027] In this embodiment, a number of limiting plates 406 are bolted together inside the mounting box 401. The limiting plates 406 are arranged vertically, and there is a gap between the limiting plates 406 in the same layer. The operating rod 501 is movably arranged in the gap between the limiting plates 406.

[0028] In this embodiment, the bottom of the limiting plate 406 is connected to the guide strip 407 by bolts, and the top of the connecting plate 502 is provided with a groove 503. When the connecting plate 502 is in a low position, the elastic telescopic rod 504 is compressed by the pressure, and its pressure is transmitted to the mating block 505, providing the mating block 505 and the screw 204 with a stable force. When the mating block 505 moves along the screw 204, the groove 503 provided on the connecting plate 502 cooperates with the guide strip 407 to prevent the connecting plate 502 from shifting when it moves.

[0029] In this embodiment, the top of the mounting box 401 is provided with a scale 408. The distribution area of ​​the scale 408 is parallel to the guide groove 405. The scale 408 can precisely control the initial position of the moving frame 402, thereby making the length of the cable pulled out from the winding wheel 201 adjustable each time it is laid.

[0030] In this embodiment, the limiting mechanism includes a lead screw 301, which is threadedly connected to the fixed plate 103. A lifting plate 303 is rotatably connected to the bottom of the lead screw 301. Several guide rods 302 are slidably connected to the lifting plate 303, and the guide rods 302 are bolted to the bottom of the fixed plate 103.

[0031] Working principle: When using this device, first install the cable on the winding reel 201, move the movable seat 101 to the cable laying position, rotate the lead screws 301 on both sides, and the lead screws 301 push the guide rod 302 towards the ground until the guide rod 302 supports the movable seat 101, thus fixing the movable seat 101. The installer adjusts the initial position of the movable frame 402 according to the site conditions. The length of the wire pulled from the winding reel 201 before and after one wire laying can be determined by the scale 408. The distance from the winding reel 201 on the scale 408 is linearly related to the length of the pulled wire. During adjustment, press the operation button. The operating rod 501 is rotated, and the insertion rod 403 drives the connecting plate 502 to rotate until the length direction of the connecting plate 502 is parallel to the length direction of the limiting plate 406. At this time, the elastic telescopic rod 504 can lift the connecting plate 502, allowing the connecting plate 502 to rise to the top position above the connecting plate 502. At this time, the mating block 505 rises a certain distance and disengages from the screw 204. Then, the moving frame 402 can be moved to a certain position on the scale 408 by operating the operating rod 501. After that, the operating rod 501 is pressed down, causing the connecting plate 502 to descend again to the horizontal plane where the guide bar 407 is located, and the operating rod 501 is rotated. This allows the guide strip 407 to enter the groove 503, while the mating block 505 descends, pressing against the screw 204 and forming a threaded engagement. After completing the above operations, the cable laying operation begins. During the laying process, the rotating disk 203 drives the winding wheel 201 to rotate via the rotating shaft 202, causing the cable on the winding wheel 201 to be pulled out. During the pulling process, the winding wheel 201 drives the screw 204 to rotate via the rotating shaft 202. The rotation of the screw 204 can drive the mating block 505 to move along the axial direction of the screw 204. Due to the engagement between the connecting plate 502 and the guide strip 407, the screw 204 is connected by the elastic telescopic rod 504. The connecting plate 502 is moved horizontally, and the connecting plate 502 moves the operating rod 501 towards the winding wheel 201. The operating rod 501 pushes the insertion rod 403 towards the locking plate 205 through the moving frame 402. After pulling out the planned length, the insertion rod 403 passes through the through hole on the side of the moving seat 101 and connects to a locking hole 206 on the locking plate 205. At this time, the rotation of the winding wheel 201 is locked. The fixed cable length can be controlled without the operator visually estimating the cable length. After marking the cable length at the position of the winding wheel 201, the above operation is repeated to complete the segmented cable laying operation.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
