Description

Technical Field

[0001] The invention relates to the technical field of cable tray assembly, in particular to a continuous reversing assembly component suitable for cable tray assembly. Background Art

[0002] In the field of cable tray assembly, especially in complex assembly scenarios involving continuous reversal, traditional assembly methods mainly rely on manual operation. This operation method has many disadvantages. Manual reversal of heavy cable trays is not only inefficient but also extremely risky and prone to safety accidents. At the same time, during the installation process of the hanger, due to the lack of an effective fixing and positioning mechanism, the hanger is prone to slipping, resulting in reduced installation accuracy and even potential safety hazards. In addition, the traditional bridge positioning, hanger installation and flip correction steps are independent of each other and require frequent manual adjustments, which not only reduces assembly efficiency, but also makes it difficult to ensure assembly accuracy and meet the high standards required for batch assembly of continuously bent bridges in large-scale projects.

[0003] In order to solve the above problems, the patent publication number CN218771053U proposes a design of an assembled cable tray, which uses modular connection components to achieve rapid splicing of the cable tray and improve assembly efficiency. However, this design still requires manual flipping and positioning of the cable tray, which fails to fundamentally solve the problems caused by manual operation. In addition, patent publication number CN222721047U focuses on the fixing and supporting structure of the cable tray. The cable tray adopts a locking structure, and the locking mechanism is used to automatically lock the cable tray, thereby simplifying the installation process. However, this type of design mainly focuses on the connection stability of the cable tray itself, and does not provide an effective solution to the anti-slip and positioning problems during the installation of the hanger.

[0004] To this end, we propose a continuous reversing assembly component suitable for cable tray assembly. Summary of the Invention

[0005] The object of the present invention is to provide a continuous reversing assembly component suitable for assembling a cable tray, so as to solve the problems mentioned in the background art.

[0006] To achieve the above object, the present invention provides the following technical solution: a continuous reversing assembly component suitable for assembling a cable tray, comprising a conveyor frame, a slide being slidably connected to the conveyor frame, a rotary table being movably connected to the side of the slide, and a centering locking mechanism being slidably connected to the top of the rotary table; A positioning frame is slidably connected in a groove provided on one side of the rotary table, a gear rod is symmetrically welded and fixed on one side of the positioning frame, a positioning sleeve is slidably connected to the gear rod, a pressure plate is installed on the positioning sleeve, a screw rod is movably connected to the top of the pressure plate, and the screw rod passes through the directional sleeve and is threadedly connected to it, sliding columns are installed on both sides of the top of the pressure plate, passing through the directional sleeve and slidably connected to it; The centering locking mechanism includes a slide arranged on the top of the slide, a slider sliding in a slot arranged on the top of the slide, a rotary rod installed on the side of the slide, and one end of the rotary rod passes through the slide and is movably connected to the side wall of the slide through a bearing, movable clamping columns are symmetrically installed and fixed on both side walls of the slider, and a positioning ring is sleeved on the outer wall of the movable clamping column for abutting and engaging the side walls when the cable tray is inverted, fixed clamping columns are symmetrically fixed on both sides of the slide, and the movable clamping columns are combined to complete the clamping of the cable tray.

[0007] Furthermore, the centering locking mechanism also includes a centering rod arranged on the top of the slide and the slider, and the ends of the two centering rods are movably connected to the slide and the slider respectively, and a laser emitter is installed at one end of the two centering rods.

[0008] Furthermore, the side wall of the positioning sleeve is slidably connected to a lock box, and spring columns are symmetrically installed on both sides of the lock box. The spring column consists of a column and a spring installed in the lock box, and the column is located on the inner wall of the lock box and abuts against the spring. One end of the spring column is fixed with a directional block by welding, and the directional block abuts against the tooth pattern of the side wall of the gear rod.

[0009] Furthermore, a threaded stud is threadedly connected to the side wall of the directional jacket and passes through the through groove on the lock box. The threaded stud is located on the inner side of the directional jacket and is fixed with a cam, and one side of the cam is in contact with the inner wall of the lock box.

[0010] Furthermore, a transmission lifting assembly is installed on the top of the conveyor frame, and a screw rod is fixed on the output end of the motor installed in the transmission lifting assembly, and one end of the screw rod passes through the slide and is movably connected to the bottom of the conveyor frame.

[0011] Furthermore, a limit plate is fixedly connected between the slides and on the conveyor frame, a limit slot is provided on the limit plate, an abutment rod is fixedly connected to the central rotating shaft of the rotary table, and one side of the abutment rod is engaged with the limit slot.

[0012] The method of using the continuous reversing assembly component suitable for cable tray assembly is as follows: The cable tray is trimmed and bent, the marked area is cut, and after manual assembly and fixation, it is placed upside down on the conveyor frame. The transmission lifting assembly controls the slide to descend, and the slide is manually driven to move. The movable clamping column and the fixed clamping column are moved to both sides of the cable tray, and the rotary rod is rotated to drive the movable clamping column to complete the clamping of both sides of the cable tray. Then move the positioning frame on the slide to the bending area of ​​the cable tray, cover the hanger required for installation on the top of the inverted cable tray, with the "U"-shaped mouth of the hanger facing down, and rotate the shaft column on the pressure plate to complete the pressing work of the hanger on the top of the cable tray. According to the laser transmitter installed in the center of the centering rod, the position of the cable tray on the conveyor rack is calibrated. Then, the transmission lifting assembly on the conveyor rack is used to drive the entire slide to lift. At the same time, the rotary table shaft column contacts the upper limit slot of the limit plate to complete a 180-degree flip, realizing the flip of the cable tray, adjusting the length of the entire hanger, and completing the assembly of the cable trays on both sides at the same time.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, a mechanical turning mechanism is adopted, and the limit plate and the limit groove are used to guide the rotary table to automatically turn 180 degrees, replacing the traditional manual turning operation of the heavy bridge. At the same time, a self-locking anti-skid structure is set, and the directional jacket is engaged with the gear rod through the spring column and the directional cut block to achieve one-way movement locking. The cam structure can quickly switch the locking direction to ensure that there is no displacement when the hanger is pressed, eliminating the risk of manual handling and avoiding the hidden danger of slipping during the installation of the hanger.

[0014] 2. In the present invention, the centering locking mechanism realizes the rapid grasping and automatic center positioning of the cable bridge through the linkage clamping of the movable clamping column and the fixed clamping column, combined with the laser centering system. At the same time, the positioning frame cooperates with the gear rod and the adjustable pressure plate to pre-fix the hanger on the inverted bridge before flipping, so as to avoid falling off during flipping, reduce manual secondary adjustment, greatly shorten the bridge positioning and hanger assembly time, and ensure the angle and position accuracy of the continuous reversing bridge at the same time. The traditional separate bridge positioning, hanger installation and flip correction steps are integrated into a single mechanical operation to solve the pain points of low efficiency, poor precision and high risk in the installation of reversing cable bridges. It is especially suitable for the batch assembly of continuously bent bridges in large-scale projects. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-8 , the present invention provides a technical solution: Example 1: The cable tray is precisely cut on its side. For ladder-type cable trays, the crossbars or side ribs are cut, and for trough-type cable trays, the side panels are cut to form a "hinge" effect. This allows the cable tray to bend at the cutting point to achieve the desired angle of deflection. Standard horizontal elbow connectors or straight connectors are also required to connect and fix the bent cable tray section to the front and rear straight cable trays to ensure a firm connection. Usually, there are multiple cutting positions, which form a continuous reversal of the cable tray. During installation, unlike conventional cable trays, hangers are usually installed for stability. Since the cable tray deviates from the installation route, manual installation is difficult. For this reason Figure 1 and Figure 2 As shown, an automatic grabbing and lifting assembly is set up to complete the joint pre-assembly of related hangers at the same time, and the positioning and flipping during the lifting process are accompanied to achieve high-speed installation of the cable tray after continuous reversal, which is convenient to operate; Different from the installation method with the opening facing upwards, such as Figure 7 As shown, this application adopts the inverted grabbing method. The operator places the cut and assembled cable tray on one side of the conveyor frame 1, and completes the clamping of both sides of the cable tray through the centering locking assembly installed on the side of the rotary table 6, as shown in FIG. Figure 3 As shown, during the specific operation, the slide 701 on the top of the slide 5 is moved to adjust the side clamp position according to the length of the cable tray; At the same time, the side rotating rod 702 of the slide 701 is manually rotated to drive the movable clamping column 704 on the slider 703 to move toward the side wall of the cable tray, and cooperate with the fixed clamping column 705 to complete the clamping of both sides of the cable tray, while improving the clamping stability of the cable tray. The outer walls of the movable clamping column 704 and the fixed clamping column 705 are fixed with a positioning ring, and the two are clamped to move the positioning ring to the bottom side wall of the cable tray to play a supporting and fixing role; After continuous reversal, the cable tray has an angle deflection. In order to install the hangers synchronously, a "U"-shaped hanger is pre-placed on the set position of the inverted cable tray. The conventional hanger is installed, and then the cable tray is inserted through it to complete the joint assembly. After the cable tray is continuously reversed, it deviates from its original route, and the bent part is locked in advance, which delays the installation sequence of the hanger. The cable tray is assembled first, and then the support of the assembled cable tray is manually completed before the hanger is installed at the bottom of the cable tray. The switching of the installation sequence reduces the overall hanger installation accuracy and increases the installation difficulty. To this end, the present invention connects and fixes the cable tray and the hanger, and then completes the mechanical fixation by flipping and lifting. At the same time, it can assist the operator in positioning. The operator only needs to complete the fixation of the relevant hanger top contact surface. The self-contained cable tray is stable, which simplifies the installation process. During the initial installation, Figure 8 As shown, the hanger needs to be placed on the inverted cable tray in advance. To prevent the hanger from sliding during subsequent flipping, it needs to be fixed at the same time. For this purpose, a positioning frame 8 is installed on the side of the rotary table 6. The positioning frame 8 can automatically adjust its placement position according to the horizontal deflection angle of the cable tray after continuous reversing, as shown in FIG. Figure 4 As shown, the side wall of the positioning frame 8 is symmetrically fixed with a gear rod 9, and the gear rod 9 is sleeved with a directional clamping sleeve 10 in sliding connection; To prevent the hanger on the side of the directional jacket 10 from sliding, the position of the directional jacket 10 is limited by the teeth on the gear rod 9, such as Figure 5 As shown, a lock box 14 is slidably connected to the side wall of the directional jacket 10. The lock box 14 moves up and down on one side of the directional jacket 10. At the same time, spring columns 15 are installed on both sides of the lock box 14. The spring column 15 consists of a column and a spring installed in the lock box 14. The column is located on the inner wall of the lock box 14 and abuts against the spring. One end of the spring column 15 is fixed with a directional cut block 16 by welding. The directional cut block 16 abuts against the tooth pattern of the side wall of the gear rod 9. The directional cut block 16 is provided with different directional sections on both sides, such as Figure 4 As shown, the back side cut surface of the directional cut block 16 of the lock box 14 abuts against the tooth pattern on the gear rod 9, resulting in the entire directional jacket 10 being pushed to the left, and the spring column 15 is constantly moving during the movement; When the gear rod 9 needs to move to the right, it is necessary to adjust the position of the entire lock box 14 on the directional jacket 10, and move the front section of the directional cut block 16 to the side of the gear rod 9. In order to adjust the position of the lock box 14, a threaded screw 12 is installed on the side wall of the directional jacket 10 and in the through groove of the lock box 14. Figure 6 As shown, the threaded stud 12 is located on the inner wall of the lock housing and is also sleeved with a cam 13. As the threaded stud 12 rotates, it enters the directional cut block 16 and drives the cam 13 to rotate. When the cam 13 rotates clockwise, the cam 13 used to support the lock box 14 gradually moves downward, causing the lock box 14 to start sliding downward, driving the entire directional cut block 16 to slide between the gear rods 9, changing the contact between the upper cut surface of the directional cut block 16 and the gear rod 9, re-realizing the definition of the driving direction of the directional jacket 10, and by limiting the position of the hanger on the cable tray, eliminating the risk of manual handling and avoiding the hidden danger of slipping during the installation of the hanger; After the position adjustment of the directional jacket 10 is completed, the hanger is placed on the top of the cable tray, and then the central axis of the pressure plate 11 on the directional jacket 10 is rotated. The pressure plate 11 moves and contacts the hanger, completing the locking of the hanger on the cable tray. At this time, the preparation work for installing the continuous reversing cable tray is completed, and the lifting, flipping and fixing process begins; like Figure 1 As shown, a transmission lifting assembly 2 is provided on the top of the conveyor frame 1, and the upper screw of the transmission lifting assembly 2 is used to rotate to realize the up and down movement of the slide 5, and a limit plate 3 is fixed between the slide 5 and the rotary table 6, and a limit groove 4 is provided on the limit plate 3. One side of the rod body set on the central axis of the rotary table 6 is engaged with the limit groove 4. As the rotary table 6 rises, the central axis rod body is blocked, causing the entire rotary table 6 to flip over, and the inverted cable tray is rotated 180 degrees; Finally, according to the contact height between the hanger and the top surface, the height position of the bridge frame is fixed before the connection is completed, waiting for the end of the cable bridge frame to be fixed and the hanger to be installed. Since the cable bridge frame is mechanically lifted as a whole and the hanger position is fixed, the operator only needs to complete the assembly of the relevant connectors, which is convenient for installation.

[0019] Example 2: Considering the installation and positioning problem of the cable tray, in order to avoid the operator frequently moving the entire conveyor frame 1 to calibrate the position of the cable tray, a centering rod 706 is set on the entire centering locking mechanism 7, such as Figure 3 As shown, the slider 703 and the top of the slide 701 are rotatably connected by a centering rod 706, and the two centering rods 706 are the same length; As the movable clamping column 704 on the slider 703 abuts against both sides of the cable tray, the slider 703 slides and drives the entire centering rod 706 to rotate. The centering rods 706 form an isosceles triangle. The laser emitters are installed at the connection positions of the centering rods 706 on both sides. As the size of the cable tray is adjusted, the slider 703 moves and the laser emitter on the centering rod 706 is always located at the center of the cable tray. To this end, when docking the cable tray, turn on the laser transmitter, use the mirror reflection principle, place a plane mirror at 45 degrees to achieve mirror reflection of the laser line, and according to whether the reflection line is aligned with the installation line, move the entire conveyor frame 1. After adjusting the overall position, control the entire slide 5 to rotate and lift, complete the calibration and placement, and then fix the hanger and connect the cable tray. The automatic centering and locking mechanism is set up to facilitate operators to locate the cable tray after continuous reversal. At the same time, it combines the traditional separate cable tray positioning, hanger installation and flip correction steps to solve the pain points of low efficiency, poor precision and high risk in the installation of reversing cable trays, and further improve the batch assembly efficiency of bent cable trays.
