[0001] The invention belongs to the technical field of circuit equipment, in particular to a cable laying device for building electromechanical installation. Background Art

[0002] Cable laying devices for building mechanical and electrical installations are devices used to support and fix electrical equipment such as cables and wires.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention cooperates with the sleeve rod and the rotating rod and other structures. By stepping on the sleeve rod, the rotating rod can provide an upward supporting force for the moving rod. When the operator needs to adjust the height of the cable after installation, the operator can reduce the force of lifting the cross bar upward. Stepping on the sleeve rod can provide an auxiliary force for lifting upward, thereby reducing the work intensity of the operator and saving more effort.

[0018] The present invention provides a combination of structures such as a trapezoidal block and a soft brush. When the cable needs to be transported, the trapezoidal block is pressed downward to move the two groups of L-shaped rods, and the two groups of soft brushes are driven to move toward the middle at the same time and fit with the outer wall of the cable. In this way, dust and impurities on the outer wall of the cable can be cleaned during the movement of the cable, thereby avoiding the problem that excessive dust on the outside of the cable affects the quality of the cable.

[0019] The present invention provides the coordination of structures such as the bracket and the clamping block. When the cable passes through the two groups of clamping blocks, the two ends of the cable will sag and contact the bracket, so that the bracket, the square block and the control board move downward, and the control board drives the two groups of connecting rods to move toward the middle, so that the two groups of clamping blocks move toward the middle at the same time, so that the clamping block can automatically clamp the cable after the cable passes through, thereby solving the problem that the operator needs to loosen the bolts to adjust the position of the clamping block before clamping the cable, which is more convenient and quick.

[0020] The present invention cooperates with structures such as a moving block and a stabilizing plate. When the height of the cross bar is adjusted and the sleeve rod is pressed, the sleeve rod drives the moving block to move downward, the two sets of hinged rods flip over, and drive the two sets of stabilizing plates to move to both sides at the same time, thereby increasing the contact area with the ground. In the process of continuous raising of the cross bar, the two sets of stabilizing plates will continue to move to both sides and increase the contact area with the ground, thereby avoiding the problem of the overall device being easy to tip over due to the excessive center of gravity caused by the raising of the cross bar.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 4As shown, the present invention provides a cable laying device for building mechanical and electrical installation, including a base 1, a top outer wall of the base 1 is fixedly connected to a fixed rod 2, an inner wall of the fixed rod 2 is slidably connected to a moving rod 5, an outer wall of the moving rod 5 is provided with a lifting mechanism 3, the lifting mechanism 3 includes a connecting block 301, a bottom outer wall of the connecting block 301 is hinged to a rotating rod 302, an outer wall of the rotating rod 302 is slidably connected to a sleeve rod 303, an outer wall of the fixed rod 2 is fixedly connected to a fixed plate 304, and an outer wall of the sleeve rod 303 is fixed A rotating shaft 305 is connected, and a wedge block 306 is fixedly connected to the outer wall of the rotating shaft 305. A fixed block 307 is fixedly connected to the top outer wall of the base 1. The inner wall of the fixed block 307 is elastically connected to a stopper 310 via a spring A308. A movable plate 309 is fixedly connected to the outer wall of the stopper 310. The top outer wall of the movable rod 5 is fixedly connected to a cross bar 6. A clamping mechanism 7 is provided on the outer wall of the bottom end of the cross bar 6. A cleaning mechanism 4 is provided on the outer wall of the front end of the cross bar 6. A stabilizing mechanism 8 is provided on the inner wall of the base 1.

[0033] The above scheme is adopted: through the four sets of universal wheels arranged at the bottom end of the base 1, the device can be pushed to the mechanical and electrical installation site of the building for use; the clamping mechanism 7 arranged on the cross bar 6 can clamp the cable, so as to install the cable; the movable rod 5 can move up and down in the inner wall of the fixed rod 2 and be fixed, so that the height of the cable after installation can be adjusted according to needs; through the lifting mechanism 3, the operator can save more effort when adjusting the height of the cable after installation, and does not need to rely entirely on hand strength to lift it; while lifting the cross bar 6, the sleeve rod 303 can be pressed downward, and the sleeve rod 303 flips around the rotating shaft 305, driving the rotating rod 302 to flip, and the rotating rod 302 moves inward along the inner wall of the sleeve rod 303 during the flipping process, and when the cross bar 6 is continued to be lifted upward, the rotating rod 302 moves outward along the inner wall of the sleeve rod 303. The movable rod 5 is exerted with an upward force, thereby reducing the force required for the operator to lift the cross bar 6 and reducing the workload; while stepping on the sleeve rod 303, the sleeve rod 303 is flipped downward to control the stabilizing mechanism 8, so that the two sets of stabilizing plates 805 move to both sides, so that when the height of the cross bar 6 is adjusted after stepping on the sleeve rod 303, the stability can be increased by the stabilizing plates 805; and during the rotation of the sleeve rod 303, the arc surface of the wedge block 306 exerts an extruding force on the arc surface of the stop block 310, so that the stop block 310 moves downward, and the spring A308 is forced to contract. When the cross bar 6 is lifted to a suitable height, the wedge block 306 pops up upward due to the elastic force of the spring A308, and its straight surface contacts the straight surface of the stop block 310, so that the sleeve rod 303 can be limited, the height of the cross bar 6 is fixed, and the cable height adjustment is completed.

[0034] like Figures 1 to 4As shown, the connecting block 301 is fixedly connected to the outer wall of the bottom end of the moving rod 5, the rotating shaft 305 is rotatably connected to the fixed plate 304, the wedge block 306 contacts the outer wall of the stop block 310, the movable plate 309 passes through the outer wall of the fixed block 307, one end of the spring A308 is fixedly connected to the outer wall of the stop block 310, and the other end of the spring A308 is fixedly connected to the inner wall of the fixed block 307, and the outer wall of the stop block 310 is slidably connected to the inner wall of the fixed block 307.

[0035] By adopting the above scheme: by stepping on the movable plate 309, the stopper 310 can be driven to move downward and disengage from the wedge block 306, thereby releasing the limit of the sleeve rod 303, and the movable rod 5 can be moved downward to adjust the height of the cable downward; a curved surface is provided on one side of the stopper 310, and when the sleeve rod 303 is stepped on, the curved surface of the wedge block 306 contacts the curved surface of the stopper 310, so that the stopper 310 can be squeezed to move it downward.

[0036] like Figure 5 As shown, the cleaning mechanism 4 includes a protrusion 401, the inner wall of the bottom end of the protrusion 401 is elastically connected to the trapezoidal block 402 through a spring B403, the inner wall of the protrusion 401 is slidably connected to two groups of L-shaped rods 404, the inner wall of the bottom end of the protrusion 401 is slidably connected to a soft brush 405, the protrusion 401 is fixedly connected to the outer wall of the cross bar 6, one end of the L-shaped rod 404 is fixedly connected to the outer wall of the soft brush 405, the other end of the L-shaped rod 404 is slidably connected to the outer wall of the trapezoidal block 402, one end of the spring B403 is fixedly connected to the outer wall of the trapezoidal block 402, the other end of the spring B403 is fixedly connected to the inner wall of the protrusion 401, and the outer wall of the trapezoidal block 402 is slidably connected to the inner wall of the protrusion 401.

[0037] The above scheme is adopted: when not affected by external force, one end of the L-shaped rod 404 maintains contact with the inclined surface of the long side of the bottom end of the trapezoidal block 402, and the two groups of soft brushes 405 are located on both sides of the protrusion 401 and do not contact the cable surface; the top of the trapezoidal block 402 passes through the top of the protrusion 401; when the cable needs to be transported, the trapezoidal block 402 can be pressed downward, and the spring B403 is forced to shrink, driving the two groups of L-shaped rods 404 to move toward the middle at the same time, so that the two groups of soft brushes 405 can move toward the middle, so that the soft brushes 405 are in contact with the outer wall of the cable, so that during the transportation and movement of the cable, the surface is rubbed by the soft brushes 405 to have a cleaning effect, and dust and other impurities attached to the surface are cleaned, so as to keep the cleanliness of the cable surface.

[0038] like Figure 6As shown, the clamping mechanism 7 includes a mounting block 701, the inner wall of the mounting block 701 is slidably connected with a connecting rod 704, the outer wall of the bottom end of the cross bar 6 is fixedly connected with a concave block 702, the inner wall of the concave block 702 is slidably connected with a clamping block 703, the inner wall of the mounting block 701 is elastically connected with a square block 705 through a spring, the outer wall of the square block 705 is fixedly connected with a bracket 706, and the outer wall of the square block 705 is fixedly connected with a control board 707; the mounting block 701 is fixedly connected to the outer wall of the bottom end of the cross bar 6, one end of the connecting rod 704 is fixedly connected to the outer wall of the clamping block 703, the other end of the connecting rod 704 is slidably connected to the through groove of the outer wall of the control board 707, the square block 705 is slidably connected to the inner wall of the mounting block 701, and the bracket 706 is slidably connected to the inner wall of the mounting block 701.

[0039] The above scheme is adopted: the clamping mechanism 7 is provided with multiple groups, and the inner wall of the concave block 702 in each group of the clamping mechanism 7 is slidably connected with two groups of clamping blocks 703, and the two groups of clamping blocks 703 can clamp the cable from both sides to keep it in the erected state; one end of the spring is fixedly connected to the outer wall of the bottom end of the square block 705, and the other end is fixed to the inner wall of the bottom end of the mounting block 701. In the case of no external force, the spring elastic force keeps the square block 705 in the upper state, such as Figure 6 As shown, in this state, the bottom ends of the two groups of connecting rods 704 keep in contact with the inner wall of the bottom end of the through groove on the control board 707, and drive the two groups of clamping blocks 703 to remain in the state of being on both sides, and the semicircular ring-shaped support plates on the two groups of brackets 706 correspond to the positions of the clamping blocks 703. When the cable passes through the two groups of clamping blocks 703, the two sides of the cable hang down due to gravity and contact the support plates on the brackets 706, which exerts pressure on the support plates, so that the brackets 706, the square blocks 705 and the control board 707 move downward at the same time, and the bottom of the square blocks 705 rebounds. The spring contracts under force, and when the control plate 707 moves downward, the inner wall of the through groove generates pressure on the bottom end of the connecting rod 704, so that the bottom ends of the two groups of connecting rods 704 move to the inner wall of the top end of the through groove. Since the connecting rod 704 is slidably connected to the inner wall of the mounting block 701, it can only move horizontally in its inner wall, so that the two groups of connecting rods 704 and the corresponding clamping blocks 703 move toward the middle at the same time, and the cable can be clamped automatically. The operator does not need to tighten the bolts and adjust the position of the clamping block 703 to perform the clamping operation, which is more convenient and quick.

[0040] When the cable needs to be transported, the two ends of the cable are pulled up, and the cable is now out of contact with the support plates on the two side brackets 706. The spring drives the square block 705 to move upward and reset due to its own elastic force, so that the control board 707 moves upward synchronously, and the through grooves thereon drive the two sets of connecting rods 704 and the clamping block 703 to move to both sides, so that they can be out of contact with the outer wall of the cable and release its clamping state.

[0041] like Figures 7 to 9As shown, the stabilizing mechanism 8 includes a telescopic rod 801, the top outer wall of the telescopic rod 801 is hinged with a slider 807, the bottom outer wall of the telescopic rod 801 is fixedly connected with a moving block 802, the bottom outer wall of the moving block 802 is hinged with a stabilizing plate 805 through a hinge rod 804, the bottom outer wall of the base 1 is fixedly connected with a guide telescopic block 806, and the bottom outer wall of the guide telescopic block 806 is fixedly connected with an inner plate 803; the slider 807 is fixedly connected to the bottom outer wall of the sleeve rod 303, one end of the hinge rod 804 is hinged to the outer wall of the stabilizing plate 805, and the other end of the hinge rod 804 is hinged to the outer wall of the moving block 802; the stabilizing plate 805 is slidably connected to the outer wall of the inner plate 803, and the outer wall of the moving block 802 is slidably connected to the inner wall of the base 1.

[0042] Adopting the above scheme: when the operator pushes the device to move, the inner plate 803 and the stabilizing plates 805 on both sides thereof are not in contact with the ground, and at this time, the guide telescopic block 806 and the telescopic rod 801 remain in the retracted state, such as Figure 9 As shown, at this time, one end of the outer side of the sleeve rod 303 drives the telescopic rod 801 and the moving block 802 to remain in the upper state, and the two sets of hinged rods 804 at the bottom of the moving block 802 flip toward the middle, so that the two sets of stabilizing plates 805 are folded; when it is moved to a suitable location, it is necessary to step down on the sleeve rod 303 to adjust the height of the cross bar 6, and the positioning bolts of the guide telescopic block 806 and the outer side of the telescopic rod 801 can be screwed in. At this time, the moving block 802, the inner plate 803, and the stabilizing plate 805 move downward due to gravity, and the guide telescopic block 806 and the telescopic rod 801 are stretched. When the stabilizing plate 805 contacts the ground, the two sets of positioning bolts are tightened, and the contact area with the ground can be increased through the stabilizing plate 805, thereby improving stability.

[0043] When the cross bar 6 is raised, the sleeve rod 303 is pressed downward, which drives the telescopic rod 801 and the moving block 802 to continue to move downward, and the slider 807 moves along the slide groove below the sleeve rod 303. The telescopic rod 801 flips along the inner wall of the slider 807 and keeps the vertical movement state. When the moving block 802 moves downward, the stabilizing plate 805 has already contacted the ground, so that the two sets of hinged rods 804 flip to both sides at the same time, driving the two sets of stabilizing plates 805 to move to both sides, thereby continuing to increase the contact area with the ground. When the center of gravity rises due to the rise, the wider supporting area can improve the stability of the device and avoid damage caused by its tipping; when the cross bar 6 moves downward and is retracted, it can drive the telescopic rod 801 and the moving block 802 to move upward, and the two sets of hinged rods 804 are flipped toward the middle to make the two sets of stabilizing plates 805 move toward the middle and reset, and then the inner plate 803, the stabilizing plate 805 and the moving block 802 are moved upward synchronously, and they can be fixed by positioning bolts to keep the stabilizing plate 805 from contacting the ground to avoid affecting the movement of the entire device.

[0044] The working principle and use process of the present invention:

[0045] The operator can use the four sets of universal wheels arranged under the base 1 to move the entire device to the work site where cables need to be laid for building mechanical and electrical installation, and then clamp the cables in the clamping mechanism 7; the clamping mechanism 7 is provided with multiple groups, and the two groups of clamping blocks 703 slidably connected to the inner wall of the concave block 702 in each group are used to clamp the cables from both sides to keep them in the laid state.

[0046] Under normal circumstances without external force, the elastic force of the spring makes the square block 705 in the upper position. At this time, the bottom ends of the two groups of connecting rods 704 contact the bottom inner wall of the through groove on the control plate 707, driving the two groups of clamping blocks 703 to be separated on both sides, and the semicircular support plates on the two groups of brackets 706 correspond to the positions of the clamping blocks 703.

[0047] When the cable passes through the two groups of clamping blocks 703, the two sides of the cable hang down due to gravity and contact the support plate on the bracket 706, which generates pressure on the support plate. This pressure causes the bracket 706, the square block 705 and the control board 707 to move downward at the same time. The spring under the square block 705 is forced to shrink. When the control board 707 moves downward, the inner wall of its through groove generates pressure on the bottom end of the connecting rod 704, so that the bottom ends of the two groups of connecting rods 704 move to the inner wall of the top end of the through groove. Since the connecting rod 704 is slidably connected to the inner wall of the mounting block 701 and can only move horizontally, the two groups of connecting rods 704 and the corresponding clamping blocks 703 move toward the middle at the same time, thereby automatically clamping the cable, thereby completing the initial erection operation.

[0048] After the installation is completed, the height of the cross bar 6 is adjusted as needed to adjust the cable to a suitable height; when raising the cross bar 6, the operator can press down on the sleeve rod 303 to make the sleeve rod 303 flip around the rotating shaft 305, thereby driving the rotating rod 302 to flip. The rotating rod 302 provides an upward supporting force for the moving rod 5, thereby saving effort when the operator lifts the cross bar 6. The operator does not need to rely entirely on hand strength to lift it, thereby reducing work intensity.

[0049] In the process of stepping on the sleeve rod 303, the arc surface of the multiple groups of wedge blocks 306 continuously contacts and squeezes the arc surface of the stopper 310, so that the stopper 310 moves downward along the inner wall of the fixed block 307, and the spring A308 is forced to shrink. When the cross bar 6 is lifted to a suitable height, the spring A308 drives the stopper 310 to move upward due to the elastic force, and the straight surface of a group of wedge blocks 306 contacts the straight surface of the stopper 310. The stopper 310 can limit the rotation shaft 305 and fix the sleeve rod 303, so that the moving rod 5 will not cause the sleeve rod 303 to move due to its own gravity. 3 is flipped, thereby fixing the height of the cross bar 6 and the cable, completing the installation and height adjustment of the cable. When the cable needs to be moved downward, the operator can step on the movable plate 309 to drive the stopper 310 to move downward and disengage from the wedge block 306, thereby releasing the limit of the sleeve rod 303. The movable rod 5 moves downward due to its own gravity, driving the sleeve rod 303 to flip, and the cable height can be adjusted downward. Due to the provision of multiple sets of wedge blocks 306, the movable rod 5 can be moved to multiple heights for fixing, so as to adapt to the installation of cables with different height requirements.

[0050] Before adjusting the height of the crossbar 6, the operator can loosen the positioning bolts on the guide telescopic block 806 and the outside of the telescopic rod 801. At this time, the moving block 802, the inner plate 803 and the stabilizing plate 805 move downward due to gravity, stretching the guide telescopic block 806 and the telescopic rod 801. When the stabilizing plate 805 contacts the ground, tighten the two sets of positioning bolts to increase the contact area with the ground through the stabilizing plate 805, thereby improving a certain degree of stability.

[0051] When the sleeve rod 303 is pressed downward to raise the cross bar 6, pressing the sleeve rod 303 will drive the telescopic rod 801 and the moving block 802 to continue to move downward, the slider 807 moves along the slide groove below the sleeve rod 303, and the telescopic rod 801 flips along the inner wall of the slider 807 to keep moving vertically. Since the stabilizing plate 805 has been in contact with the ground when the moving block 802 moves downward, the two sets of hinged rods 804 are flipped to both sides at the same time, driving the two sets of stabilizing plates 805 to move to both sides and continue to increase the contact area with the ground. Therefore, the unfolding distance of the two sets of stabilizing plates 805 can be adjusted according to the degree of pressing and flipping of the sleeve rod 303. According to the height of the center of gravity after the cross bar 6 is raised, the contact area of ​​the stabilizing plate 805 with the ground is increased accordingly, thereby improving stability and avoiding the problem of the device having a high center of gravity and easy tipping.

[0052] When the cross bar 6 moves downward and is retracted, the telescopic rod 801 and the moving block 802 move upward, and the two sets of hinged rods 804 flip toward the middle to make the two sets of stabilizing plates 805 move toward the middle and reset. Then the inner plate 803, the stabilizing plate 805 and the moving block 802 move upward synchronously and are fixed by positioning bolts to keep the stabilizing plate 805 from contacting the ground so as not to affect the movement of the entire device.

[0053] When it is necessary to transport the installed cables, the operator can clean the impurities on the cable surface through a cleaning mechanism 4 corresponding to a group of cables. At this time, the two sides of the cable can be lifted up to disengage from the bracket 706, so that the spring drives the square block 705 and the control board 707 to reset, and the two groups of connecting rods 704 and the clamping block 703 are driven to move to both sides through the control board 707 to release the chicken wing state of the cable; then the trapezoidal block 402 is pressed downward, the spring B403 is forced to shrink, and drives the two groups of L-shaped rods 404 to move along the hypotenuse of the trapezoidal block 402, and the two groups of L-shaped rods 404 move to the sides at the same time. The two sets of soft brushes 405 can move inward, driving the two sets of soft brushes 405 to move inward. The two sets of soft brushes 405 can contact the surface of the cable. During the cable transportation process, the impurities on the cable surface can be scraped and cleaned to prevent the cable from being used in an environment with too much dust outside. Excessive surface dust affects the heat dissipation or quality of the cable. After cleaning, the trapezoidal block 402 can be loosened, and the spring B403 drives the trapezoidal block 402 to move upward and reset due to the elastic force, so that the two sets of L-shaped rods 404 drive the two sets of soft brushes 405 to move to both sides, keeping the soft brushes 405 on both sides without affecting the installation of the cable.
