Description

Technical Field

[0001] The utility model relates to a bridge structure, in particular to a trough type cable bridge and a mounting bracket thereof. Background Art

[0002] As an important component of the cable wiring system, trough-type cable tray has many advantages such as simple structure, strong load-bearing capacity, good corrosion resistance and good cable protection.

[0003] Its simple structural design, primarily composed of a U-shaped tray and cover, makes it easy to install and quickly adapt to various construction environments and cable laying requirements. This type of cable tray has a strong load-bearing capacity, effectively supporting and protecting cables, ensuring safe and stable cable laying. Furthermore, trough-type cable trays utilize anti-corrosion treatments such as hot-dip galvanizing, resulting in excellent corrosion resistance. This allows for long-term use in a variety of complex environments without damage, further extending the service life of the cables. Furthermore, its closed or semi-closed design effectively prevents corrosion from external factors such as dust and moisture, providing excellent cable protection.

[0004] When installing trough-type cable trays, the trays are laid first, followed by the wiring, and finally the cover plates. However, due to the lack of a stable connection between the cover plates, trays, and mounting brackets, the trays, cover plates, and mounting brackets are prone to movement and displacement when subjected to external forces, resulting in stability issues. Utility Model Content

[0005] The purpose of the present invention is to provide a trough-type cable tray and a mounting bracket thereof to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A trough type cable bridge comprises a galvanized trough plate, wherein the galvanized trough plate is in a "U" shape and has a notch formed on the upper portion;

[0008] The trough-type cable tray also includes a cover plate arranged at the trough for closing the trough, the cover plate is provided with a slot for cooperating with the mounting bracket, and the side of the galvanized trough plate is provided with an inlay.

[0009] The mounting bracket of the trough-type cable tray as described above: the mounting bracket includes a joist for supporting the bottom of the galvanized trough plate, side beams are installed above both sides of the joist, and the side beams are movably provided with an insert for cooperating with the embedding, and the side beams are also movably provided with a clamping block for cooperating with the clamping slot;

[0010] A lifting screw rod for connecting with the top of a building is vertically installed on the side edge of the side beam.

[0011] The mounting bracket of the trough-type cable tray as described above: a row of mounting holes are provided on both sides of the joist at equal intervals along the length direction of the joist, and fixing holes for cooperating with the mounting holes are provided at the lower part of the side beam.

[0012] The mounting bracket of the trough-type cable tray as described above: the side beam and the insert are connected by a threaded adjustment structure parallel to the joist, the threaded adjustment structure comprising a lead screw rotating on the side beam, a sleeve connected to the side beam, and a solenoid fixed on a side of the insert close to the side beam;

[0013] The insert is in sliding engagement with the housing, and the lead screw is in threaded engagement with the solenoid, an end of the lead screw away from the solenoid is formed with an external hexagonal portion, and an end of the insert away from the side beam has a cone angle.

[0014] The mounting bracket of the trough-type cable tray as described above: the clamping block is vertically movably arranged on the side beam along the length direction of the side beam through a follower block, and a socket is provided in the center of the follower block, and an insert block is fixedly inserted into the socket, and two sides of the insert block are respectively connected to two sides of the insert block through two connecting rods;

[0015] One end of the connecting rod is rotatably connected to the insert block, the other end of the connecting rod is rotatably connected to the insert block, and the clamping block is connected to the follower block.

[0016] The mounting bracket of the trough-type cable tray as described above: a track plate is fixedly provided on one side of the side beam along its length direction, and the track plate is provided with a follower groove that vertically movably cooperates with the follower block;

[0017] Through slots are provided on both sides of the following slot, and the inserting block passes through the through slots on both sides of the following slot to be connected to the connecting rod.

[0018] The mounting bracket of the trough-type cable tray as described above: a set of hemispherical recesses are respectively provided on both sides of the follower block, and balls are universally rolled and embedded in the hemispherical recesses;

[0019] Straight raceways are provided on both sides of the follower groove, and the balls are in rolling engagement with the straight raceways.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: when installing the cable bridge, the galvanized trough plate is first laid, and then the cable is laid in the galvanized trough plate from the notch. After the cable is laid, the cover plate is covered on the notch. Since an embedded opening is opened on the side of the galvanized trough plate and a card slot is opened on the cover plate, when the bridge needs to be fixed to the mounting bracket, the embedded opening and the mounting bracket are respectively matched, so that the galvanized trough plate cannot move up and down and forward and backward relative to the mounting bracket. At the same time, the card slot and the mounting bracket are matched to make the cover plate tightly pressed at the notch and also cannot move forward and backward.

[0021] The bottom of the galvanized trough plate is supported by the joist. When the block moves downward, the cover plate is driven to fit tightly against the notch, and the cover plate applies a downward force to the notch above the galvanized trough plate, so that the bottom of the galvanized trough plate is in close contact with the joist. In this way, it can be ensured that there is no looseness between the cover plate and the notch.

[0022] In addition, under the action of the embedding blocks and the embedding grooves, the galvanized trough plate is restricted in its forward and backward movement while being unable to move up and down, and no movement occurs; similarly, under the action of the clamping blocks and the clamping grooves, the forward and backward movement of the cover plate that cannot move up and down is also restricted.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] See also Figures 1 to 8 As an embodiment of the present invention, the trough type cable tray comprises a galvanized trough plate 1, wherein the galvanized trough plate 1 is in a "U" shape and has a notch formed on the top;

[0034] The trough type cable tray further comprises a cover plate 2 arranged at the trough for closing the trough, the cover plate 2 is provided with a slot 201 for cooperating with the mounting bracket, and an inlay 101 is provided on the side of the galvanized trough plate 1.

[0035] In this embodiment, when installing the cable bridge, the galvanized trough plate 1 is first laid, and then the cable is laid in the galvanized trough plate 1 from the notch. After the cable is laid, the cover plate 2 is covered on the notch. Since an inlay 101 is provided on the side of the galvanized trough plate 2 and a card slot 201 is provided on the cover plate 2, when the bridge needs to be fixed to the mounting bracket, the inlay 101 and the mounting bracket are respectively matched, so that the galvanized trough plate 1 cannot move up and down and forward and backward relative to the mounting bracket. At the same time, the card slot 201 is matched with the mounting bracket so that the cover plate 2 is tightly pressed at the notch and cannot move forward and backward.

[0036] In addition, the present application also proposes a mounting bracket that cooperates with the above-mentioned trough-type cable tray, the mounting bracket including a joist 3 for supporting the bottom of the galvanized trough plate 1, side beams 4 are installed above both sides of the joist 3, and the side beams 4 are movably provided with an insert 6 for cooperating with the inlay 101, and the side beams 4 are also movably provided with a clamping block 5 for cooperating with the clamping slot 201;

[0037] A lifting screw 15 for connecting to the top of a building is vertically installed on the side edge of the side beam 4.

[0038] In this embodiment, the bottom of the galvanized trough plate 1 is supported by the support beam 3, and the cover plate 2 is driven to fit tightly against the notch during the downward movement of the clamping block 5, so that the cover plate 2 applies a downward force to the notch above the galvanized trough plate 1, so that the bottom of the galvanized trough plate 1 is in close contact with the support beam 3. In this way, it can be ensured that there is no looseness between the cover plate 2 and the notch.

[0039] In addition, under the action of the embedment block 6 and the embedment 101, the galvanized trough plate 1 is restricted in its forward and backward movement while being unable to move up and down, and no movement occurs; similarly, under the action of the clamping block 5 and the clamping groove 201, the forward and backward movement of the cover plate 2, which is unable to move up and down, is also restricted.

[0040] As a further solution of the present invention, a row of mounting holes are provided on both sides of the joist 3 at equal intervals along the length direction of the joist 3 , and fixing holes for cooperating with the mounting holes are provided on the lower portion of the side beam 4 .

[0041] In this embodiment, since mounting holes are arranged in rows on both sides of the joist 3, the side beam 4 can be adjusted in position according to the actual width of the galvanized trough plate 1. After adjustment, the side beam 4 and the joist 3 are fixed by bolts passing through the mounting holes and the fixing holes at the corresponding positions, so as to be able to adapt to trough-type cable trays of different widths.

[0042] As a further solution of the present invention, the side beam 4 is connected to the insert 6 by a threaded adjustment structure parallel to the joist 3, the threaded adjustment structure comprising a screw 7 rotating on the side beam 4, a housing 9 connected to the side beam 4, and a solenoid 8 fixed on a side of the insert 6 close to the side beam 4;

[0043] The insert 6 is in sliding engagement with the housing 9 , and the lead screw 7 is in threaded engagement with the solenoid 8 , wherein an outer hexagonal portion is formed at one end of the lead screw 7 away from the solenoid 8 , and a taper angle is formed at one end of the insert 6 away from the side beam 4 .

[0044] In this embodiment, the screw 7 can be driven to rotate by engaging the hexagonal portion of the inner hexagonal wrench with the outer hexagonal portion of the end of the screw 7. The rotation of the screw 7 acts on the screw tube 8, which drives the insert 6 to slide along the housing 9, and eventually approaches or moves away from the insert 101 on the side of the galvanized trough plate 1.

[0045] The purpose of providing the end of the insert 6 away from the side beam 4 with a tapered angle is to assist in the positioning and calibration of the insert 6 and the insert opening 101 .

[0046] As a further solution of the present invention, the clamping block 5 is vertically movably arranged on the side beam 4 along the length direction of the side beam 4 through a follower block 11, and a socket 1101 is provided in the center of the follower block 11. An insert block 13 is fixedly inserted into the socket 1101. The two sides of the insert block 13 are respectively connected to the two sides of the insert block 6 through two connecting rods 14.

[0047] Specifically, one end of the connecting rod 14 is rotatably connected to the insert block 13 , the other end of the connecting rod 14 is rotatably connected to the insert block 6 , and the clamping block 5 is connected to the follower block 11 .

[0048] In this embodiment, during the process of the inserting block 6 being inserted into the inserting opening 101 , the connecting rod 14 drives the following block 11 to move downward, and the following block 11 drives the clamping block 5 to move downward.

[0049] Correspondingly, when it is necessary to dismantle the cable tray or remove the cover plate 2, it is only necessary to rotate the lead screw 7 in the reverse direction.

[0050] As a further solution of the present invention, a track plate 10 is fixedly provided on one side of the side beam 4 along its length direction, and a follower groove 1001 is provided on the track plate 10 to vertically movably cooperate with the follower block 11;

[0051] Through slots 1003 are formed on both sides of the following slot 1001 , and the insert block 13 passes through the through slots 1003 on both sides of the following slot 1001 to connect with the connecting rod 14 .

[0052] In this embodiment, the track plate 10 and the follower groove 1001 are provided so that the follower block 11 can and can only move vertically along the length direction of the side beam 4 .

[0053] As a further solution of the present invention, in order to reduce the resistance of the follower block 11 to the movement in the follower groove 1001, a set of hemispherical recesses are respectively provided on both sides of the follower block 11, and a ball 12 is universally rolled and embedded in the hemispherical recesses;

[0054] Straight raceways 1002 are provided on both sides of the follower groove 1001 , and the balls 12 are in rolling engagement with the straight raceways 1002 .
