Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of cable bridge support devices, and in particular to a cable bridge support device and method for installing fully enclosed corrosion-resistant cables. Background Art
[0002] The temporary support device during cable tray installation is an auxiliary tool used for temporary positioning, load-bearing and adjustment before the cable tray is officially fixed. Its function is to ensure that the cable tray maintains a stable horizontality, verticality or preset position during the installation process, facilitates the subsequent precise connection with permanent support devices (such as brackets, hangers, etc.), avoids displacement and deformation due to the cable tray's own weight or external forces, and ensures installation accuracy and construction safety.
[0003] According to Chinese Patent Publication No. CN110571728B, an adjustable support frame for bridge installation includes two vertical support beams and a transverse support plate. The top ends of the two vertical support beams are mounted on the ceiling of the room. The middle portions of the vertical wall panels of the two vertical support beams have vertical adjustment slots. The upper and lower portions of the outer walls of the two vertical wall panels are fixed with connecting plates. Two vertical adjustment screws are hinged to the corresponding connecting plates via bearings. The bottom ends of the vertical adjustment screws extend out of the lower connecting plate and are fixed with rotating blocks. The two vertical adjustment screws are each screwed with an adjustment block, and the ends of the transverse support plate are mounted on the corresponding two adjustment blocks. The height of the transverse support plate can be adjusted by simply rotating the rotating block, which facilitates adjustment and ensures that the height of the transverse support plates of all support frames is uniform, meeting installation requirements.
[0004] When adjacent cable trays are assembled, and the assembly of cable trays is mostly in mid-air, if there is no appropriate support, deviations are likely to occur during assembly, which increases the difficulty of connection and reduces the accuracy of connection; and the shapes and angles of cable trays at the connection points are varied. Cable trays have straight plates, curved plates, etc. The cable trays also have to adjust the tilt angle according to the actual construction environment. Fixed support devices are difficult to adapt to numerous installation adjustment requirements. Summary of the Invention

[0039] The second end plate 62 is a rectangular plate. The width of the second end plate 62 is equal to the width of the first end plate 42. The length of the second end plate 62 is greater than the length of the first end plate 42. The second end plate 62 consists of a semicircular plate and a rectangular plate at one end of the semicircular plate.
[0040] The second end plate 62 is designed to change its width after rotation. Therefore, the length of the second end plate 62 is greater than its width. Typically, the length of the second end plate 62 is 2-4 times its width. Due to the effective support position at the bottom of the adjacent bridge frame, the length of the second end plate 62 can also be longer. The second end plate 62 can be configured as a telescopic plate for practical use. However, the first end plate 42 does not have this requirement. From a cost-saving perspective, the length of the first end plate 42 can be much smaller than the second end plate 62.
[0041] When the second end plate 62 is in the first position, the semicircular plate of the second end plate 62 is opposite to the first end plate 42, and the lower bent plate 63 or the second end plate 62 supports the bridge frame. When the second end plate 62 rotates 90° to reach the second position, the upper bent plate 64 or the second end plate 62 supports the bridge frame.
[0042] The bending member 7 includes: an inner box 72, the bottom of the inner box 72 is connected to the top of the stepping motor 31 through a vertical plate, an air hole 73 is opened through one side of the inner box 72, the bottom of the inner box 72 is connected to the outer box 71, a plurality of air holes 75 are opened through the bottom of the outer box 71 and the bottom ends of the air holes 75 pass through the top of the inner box 72, the outer box 71 is connected to the inner box 72 through the air holes 75, and a pneumatic box 77 is provided above each air hole 75, and the two sides of the pneumatic box 77 are connected to the limiting plates 79, and the top of the pneumatic box 77 is connected to the pressure head 74, and the top wall of the pressure head 74 is connected to the top of the inner box 72 through the third spring 78.
[0043] The inner wall of the outer box 71 is connected with a baffle, which is located directly below the limit plate 79. When the baffle abuts against the limit plate 79, a gap is left between the top of the pneumatic box 77 and the inner box 72.
[0044] The air hole 75 is composed of two semicircular ring holes, and each air hole 75 is directly opposite to the pneumatic box 77. The outer box 71 is arranged below the lower curved plate 63, and the lower curved plate 63 is an elastic shaping plate.
[0045] A cable tray support method is applied to a cable tray support device for fully enclosed corrosion-resistant cable installation. The shape and angle of the bridge at the connection point are determined. The bottom plate 11 moves to the bottom of the two bridges, and the stepper motor 31 is started. The first end plate 42 and the second end plate 62 move closer to or away from each other along the direction of the screw. The telescopic end of the first liquid oxygen cylinder moves up with the lifting support member 4 and the rotating support member 6. The first end plate 42 and the second end plate 62 respectively abut against a bridge bottom plate 11. When the bridge is an inclined plate, the second hydraulic cylinder 46 drives the rotating plate 44 to rotate, so that the rotating plate 44 is adapted to the bottom plate 11 of the inclined bridge. The rotating plate 44 supports the bridge. When the bridge is a horizontal curved plate, When the plate is turned, and the projection boundary of the horizontal bent plate exceeds the projection boundary of the second end plate 62, the second end plate 62 is rotated horizontally and fixed, and the second end plate 62 is transformed between the horizontal and vertical states, changing the contact area between the second end plate 62 and the bridge frame, so that the second end plate 62 can adapt to the horizontal straight plate and the horizontal bent plate. When the bridge frame is a lower bent plate 63, the bridge frame is pre-covered on the lower bent plate 63 to form a limited interface for the upward movement of the lower bent plate 63. Through the starting action, all the pressure heads 74 are controlled to move along the wind direction of the vertical outer box 71. The pressure heads 74 squeeze the lower bent plate 63 and bend the lower bent plate 63 toward the shape of the bridge, adapting to bridge frames of various shapes and bending or tilt angles.
[0046] When in use, push the bottom plate 11 to move the entire device to the bottom of the two bridge frames to be connected, determine the position of the support points of the two bridge frames, start the stepper motor 31, and the rotating end of the stepper motor 31 moves the wire drum 33, the first support rod 41, the second support rod 61, the first end plate 42, and the second end plate 62 in turn. The first end plate 42 and the second end plate 62 move closer to or away from each other along the axial direction of the screw rod, and the first end plate 42 and the second end plate 62 move to the bottom near the support point and then stop moving, and start the first hydraulic cylinder 12. The telescopic end of the first hydraulic cylinder 12 moves the connecting plate 34, the screw rod, the first end plate 42, and the second end plate 62 upward, and the first end plate 42 and the second end plate 62 support one bridge frame respectively. The separation distance between the first end plate 42 and the second end plate 62 is determined by the distance between the two bridge frames and the support point position at the bottom of the bridge frame, and can be adjusted according to the actual use environment.
[0047] When one bridge frame is an inclined plate, a height difference is formed between the two bridge frames. The lifting support 4 is placed under the inclined bridge frame, and the second hydraulic cylinder 46 is started. The telescopic end of the second hydraulic cylinder 46 moves the cylinder 49, the side plate 45, and the bottom end of the rotating plate 44 in turn. The two sides of the top of the rotating plate 44 are rotatably connected to the rotating cylinder 43 through the rotating rod 48. The rotating plate 44 rotates, and the inclination angle of the rotating plate 44 changes until the inclination angle of the rotating plate 44 is adapted to the bottom of the bridge frame.
[0048] When a bridge is a horizontal curved plate, the width of the second end plate 62 is relatively small, and the contact area between the second end plate 62 and the horizontal curved plate in the width direction is small, making the second end plate 62 unable to effectively support the horizontal curved plate. In this case, the plug 65 is removed and the second end plate 62 is rotated. The second end plate 62, the upper curved plate 64, and the lower curved plate 63 as a whole rotate within the second support rod 61 along with the slide rod 69. After rotating 90 degrees, the original length direction and width direction of the second end plate 62 are reversed. At this time, the second end plate 62 has a large contact area with the horizontal curved plate in the width direction, which can accommodate a variety of horizontal curved plates with different curvatures.
[0049] The curved plates in the vertical direction are divided into upper arc plates and lower arc plates. In each installation process, there are usually more lower arc plates or only lower arc plates, so the focus is on adapting to the lower arc plates.
[0050] When a bridge frame is equipped with a lower curved plate, the second end plate 62 is maintained in the first position. The curvature of each lower curved plate is determined based on the actual installation environment. Some construction sites have custom lower curved plates. To meet the support requirements of all lower curved plates, the supporting lower curved plate 63 must also be adaptable to various curvatures. Because the various lower curved plates are mostly quarter-circular plates, the bending angles of the various lower curved plates vary slightly. Lower curved plate 63 is configured as an elastically plastic curved plate, capable of a certain degree of deformation under the action of extrusion force. A lower curved plate to be installed can be placed on the upper surface of the adaptable bending member 7 and restricted from upward movement. The fan 21 is then started. Air from the fan 21 enters the air cavity 76 through the duct 22 and the air holes 73. The air in the air cavity 76 enters the outer box 71 through the air holes 73, increasing the wind pressure in the outer box 71. The pneumatic box 77 moves upward, along a line perpendicular to the curved surface of the outer box 71, along with the pressure head 74. The pressure head 74 contacts and presses the lower curved plate 63, which is located between the pressure head 74 and the lower curved plate to be installed. The lower curved plate 63 continuously bends and adapts to the curved surface at the bottom of the lower curved plate. The wind pressure simultaneously controls the expansion and contraction of all the pressure heads 74.
[0051] The rotatable second end plate 62 is an extended plate, and an upper curved plate 64 and a lower curved plate 63 are distributed on the side of the second end plate 62 to reduce the occupied space and adapt to arc plates with different bending directions. The arc plates can be flexibly adapted through rotation.
[0052] The inclined bridge can be adapted by lifting the support member 4, the curved bridge can be adapted by rotating the support member 6, and the horizontal bridge can be supported by two end plates with adjustable distances. It can adapt to various forms of bridges during the installation process and has strong adaptability.

Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.
[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention.
