Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to a cable bridge with adjustment and fixing functions. Background Art

[0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, brackets and installation accessories. The cable tray can be erected independently in the building, or it can be laid on various buildings (structures) and pipe gallery brackets. The cable tray has the characteristics of simple structure, beautiful shape, flexible configuration and convenient maintenance.

[0003] In order to ensure the stability of the cables on the current ladder-type cable tray, it is necessary to use a clamp to fix the cables on the tray. The clamp is generally a long metal sheet bent into a triangle and locked at the ends with screws. The cables are clamped in the metal sheet. This fixing method is greatly restricted. The number of fixed cables is mostly fixed, and it is difficult to make corresponding changes according to the increase or decrease in the number of cables, which is not convenient for increasing or decreasing the number of cables. Utility Model Content

[0004] The purpose of the utility model is to provide a cable tray with adjustment and fixing functions to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A cable bridge with adjustment and fixing functions comprises a bridge body, the bridge body comprises two symmetrically arranged side plates, a plurality of cross arms spaced along the length direction are arranged between the two side plates, a limit plate parallel to the cross arm is arranged on the top, guide blocks with T-shaped structures are symmetrically arranged on both sides of the limit plate, clamping plates are symmetrically arranged on both sides of the bottom end surface of the limit plate, a threaded drive groove is penetrated through the middle of the cross arm, a threaded drive rod is screwed in the threaded drive groove, the top of the threaded drive rod extends to the outside of the threaded drive groove and is rotatably connected to the bottom of the limit plate, and the bottom of the threaded drive rod extends to the outside of the threaded drive groove and is provided with a driving handwheel.

[0007] As a preferred technical solution of the utility model, a plurality of evenly distributed buffer springs are provided between the clamping plate and the limiting plate, one end of the buffer spring is fixedly connected to the top end surface of the clamping plate, and the other end of the buffer spring is fixedly connected to the bottom end surface of the limiting plate.

[0008] As a preferred technical solution of the utility model, a plurality of guide grooves capable of allowing the guide block to move up and down are provided on the inner side of the side plate.

[0009] As a preferred technical solution of the utility model, protective plates slidably connected to the limit plates are symmetrically provided on the top end surfaces of the cross arms on both sides of the threaded drive groove, and a fixing plate is provided on the top of the protective plate extending to the outside of the limit plate.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] When the cable is in use, the staff puts the cable between the cross arm and the limit plate, rotates the driving hand wheel to drive the threaded driving rod to rotate, and then drives the limit plate to move downward along the guide groove and gradually approach the cross arm, so as to compress and fix the cable, so that the cable is not easy to shake and avoid its entanglement. When the bottom of the clamping plate contacts the top of the cable and generates extrusion pressure, the clamping plate moves upward and compresses the buffer spring. Under the action of the elastic force of the buffer spring, the cable can be prevented from being compressed too tightly and causing damage to the cable surface. When the number of cables needs to be increased or decreased, the driving hand wheel is rotated according to the above steps in the opposite direction, so that the limit plate moves upward along the guide groove and gradually moves away from the cross arm, thereby loosening the cable and leaving enough space between the cross arm and the limit plate, which is convenient for the staff to increase or decrease the number of cables. The utility model has a simple structure and is easy to operate. The number of cables can be increased or decreased according to the needs of the construction site on the bridge frame body after the cables are fixed, thereby improving the practicability, flexibility and environmental applicability of the bridge frame body.

In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0018] Example

[0019] Combination Figure 1-3 A cable bridge with adjustment and fixing functions shown in the figure includes a bridge body 1, wherein the bridge body 1 includes two symmetrically arranged side plates 11, and a plurality of cross arms 12 are arranged between the two side plates 11 at intervals along the length direction thereof, and a limiting plate 13 is provided on the top of the cross arm 12 and is parallel to the cross arm 12, and guide blocks 131 with T-shaped structures are symmetrically provided on both sides of the limiting plate 13, and clamping plates 132 are symmetrically provided on both sides of the bottom end surface of the limiting plate 13, and a threaded driving groove 121 is opened through the middle part of the cross arm 12, and a threaded driving rod 133 is screwed in the threaded driving groove 121, and the top of the threaded driving rod 133 extends to the outside of the threaded driving groove 121 and is rotatably connected to the bottom of the limiting plate 13, and the bottom of the threaded driving rod 133 extends to the outside of the threaded driving groove 121 and is provided with a driving hand wheel 134.

[0020] A further optimization solution is that a plurality of evenly distributed buffer springs 135 are provided between the clamping plate 132 and the limit plate 13, one end of the buffer spring 135 is fixedly connected to the top end face of the clamping plate 132, and the other end of the buffer spring 135 is fixedly connected to the bottom end face of the limit plate 13. Through the setting of the buffer spring 135, the elastic force of the buffer spring 135 can prevent the cable from being pressed too tightly and causing damage to the cable surface.

[0021] A further optimization scheme is that a plurality of guide grooves 111 are provided on the inner side of the side plate 11 for the guide block 131 to move up and down. Through the setting of the guide block 131 and the guide groove 111, not only the displacement of the limit plate 13 can be guided and limited, but also the stability of the up and down displacement of the limit plate 13 is improved, thereby avoiding the phenomenon of shaking when the staff rotates the driving hand wheel 134 to drive the limit plate 13 to move.

[0022] A further optimization scheme is that protective plates 122 which are slidably connected to the limit plate 13 are symmetrically provided on the top end surfaces of the cross arms 12 on both sides of the threaded drive groove 121. Through the setting of the protective plates 122, damage to the cable surface caused by friction between the rotation of the threaded drive rod 133 and the cable can be avoided. A fixed plate 123 is provided on the top of the protective plate 122 extending to the outside of the limit plate 13.

[0023] The working principle of the utility model of a cable bridge with adjustment and fixing function:

[0024] When in use, the staff puts the cable between the cross arm 12 and the limit plate 13, rotates the driving hand wheel 134 to drive the threaded driving rod 133 to rotate, and then drives the limit plate 13 to move downward along the guide groove 111 and gradually approach the cross arm 12, so as to press and fix the cable to prevent the cable from shaking and entanglement. When the bottom of the pressing plate 132 contacts the top of the cable and generates a squeezing force, the pressing plate 132 moves upward and compresses the buffer spring 135. Under the action of the elastic force of the buffer spring 135, the cable can be prevented from being pressed too tightly and causing In the case where the cable surface is damaged and when it is necessary to increase or decrease the number of cables, the driving hand wheel 134 is rotated in the opposite order of the above steps to move the limit plate 13 upward along the guide groove 111 and gradually away from the cross arm 12, thereby loosening the cables and leaving enough space between the cross arm 12 and the limit plate 13, which is convenient for the staff to increase or decrease the number of cables. The utility model has a simple structure and is easy to operate. It can increase or decrease the number of cables according to the needs of the construction site on the bridge body 1 after fixing the cables, thereby improving the practicality, flexibility and environmental applicability of the bridge body 1.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
