Description

Technical Field

[0001] The utility model belongs to the field of construction facilities, and more specifically relates to an electrically controlled opening and closing cable trench cover. Background Art

[0002] In industrial and civil systems, laying cables in cable trenches has the characteristics of good heat dissipation, repeatable laying, convenient construction, and convenient maintenance. Therefore, the cable laying method in electrical rooms is generally laying in cable trenches, and the outdoor cable laying method for industrial metallurgy is generally laying in outdoor cable trenches.

[0003] At present, indoor cable trench covers are mainly steel covers, weighing about dozens of kilograms per piece, while outdoor cable trench covers are mainly reinforced concrete covers, and large covers generally weigh about hundreds of kilograms per piece. In recent years, due to the overcapacity of most metallurgical and other industries, new projects have gradually decreased and have shifted to upgrading and reconstruction. During construction, the renewal and laying of cables often requires the use of existing laying paths, so it is necessary to open multiple cable trench covers at different locations to facilitate the work of construction workers.

[0004] The traditional method of opening the cover is to open it manually with a crowbar, and then carry it manually or by sucking it with a suction cup. Faced with the aging and reduction of labor force, it seems a bit difficult to open and reset the thick and heavy cable trench cover. In addition, manual opening and carrying of cable trench cover is inefficient and has great safety risks. At the same time, the cable trench cover and cable trench wall are also very destructive during the repetitive handling process, which increases the overall construction cost invisibly.

[0005] The Chinese patent application number is CN202320563821.0, and the patent document with the publication date of August 11, 2023 discloses a cable trench cover with an opening and closing function, which includes a U-shaped base frame, a cover body, a screw and a bidirectional motor. A rotating seat is fixedly installed on the top of both sides of one end of the U-shaped base frame by bolts, and the cover body is movably connected between the rotating seats through a rotating shaft. The center of the end of the U-shaped base frame away from the rotating seat is connected to a bidirectional motor through a support rod. The output end of the bidirectional motor is fixedly installed with a rotating rod, and the top end of the rotating rod is welded and fixed with a first bevel gear. The bearing seat is fixedly installed at both ends of the U-shaped base frame by bolts. The meshing of the first bevel gear drives the second bevel gear and the screw to rotate stably on the bearing seat. The movable block on the screw realizes back and forth movement under the limitation of the hinged rod during the rotation process. The movable block moves back and forth in the screw to lift up one end of the cover body on the rotating seat through the hinge and the hinged rod, so as to realize the opening and closing of the cable cover.

[0006] However, although this patent realizes the opening and closing of the cover without the help of manpower, after the cover is opened, one end is fixed in the original position, and the other end is lifted from the original position. When people enter and exit the cable trench, it is easy to scratch the cover. If the cover fails and falls to the ground, it will cause harm and damage to the personnel, the cover itself, and the cable trench wall. In addition, the device uses multiple screws, support rods, hinges and other components, and its structure is relatively complex, which may cause inconvenience in later maintenance. And because the bottom of the device needs to use a U-shaped base frame, it needs to occupy a large space at the bottom of the cable trench, which invisibly increases the depth of the cable trench and the manufacturing cost. Summary of the invention

[0009] 2. Technical solution

[0012] As a further improvement of the technical solution, a bracket is fixedly installed on the bottom of the fixed cover plate, and the bracket is fixedly connected to the driving device.

[0013] As a further improvement of the technical solution, the driving device includes a motor, a screw and a nut; one end of the screw is transmission-connected to the motor, and the other end passes through and is threadedly connected to the nut, and the nut is fixedly connected to the movable cover plate.

[0014] As a further improvement of the technical solution, the screw is arranged tilted, and the tilt angle is consistent with the tilt angle of the bevel structure.

Therefore, the scope of the present invention is limited only by the appended claims.

[0030] Example 1

[0031] like Figures 1 to 3 As shown, an electrically controlled opening and closing cable trench cover comprises adjacent fixed cover 1 and movable cover 2, wherein the contact position of fixed cover 1 and movable cover 2 has an angled structure 4, that is, the contact surfaces of fixed cover 1 and movable cover 2 are both inclined surfaces. Fixed cover 2 is fixedly mounted on the cable trench, and a bracket 5 is fixedly mounted below the fixed cover 2, and a driving device 3 is fixedly connected to the bracket 5, and the driving device 3 drives the movable cover 2 to move along the inclined direction of the angled structure 4.

[0032] Specifically, the driving device 3 includes a motor 31, a screw 32 and a nut 33. The motor 31 is fixedly connected to the bracket 5, one end of the bolt 32 is transmission-connected to the motor 31, and the other end passes through and is threadedly connected to the nut 33, and the nut 33 is fixedly connected to the movable cover plate 2. In this embodiment, the screw 32 is arranged obliquely, and the inclination angle is consistent with the inclination angle of the angled structure 4, so that the movable cover plate 2 can be moved to the bottom of the fixed cover plate 1 at the minimum inclination angle, that is, the inclination angle of the angled structure 4, to avoid descending too deep and causing the equipment to occupy too much space. It should be noted that the height to which the movable cover plate 2 descends cannot be higher than the distance between the end of the screw 32 and the fixed cover plate 1 in the vertical direction.

[0033] An inclined groove is provided on the side wall of the cable trench, and the bottom of the movable cover plate 2 has a support member 6 supported and arranged in the groove, and the inclination angle of the groove is consistent with the inclination angle of the bevel structure 4. In this way, the movable cover plate 2 can be supported and arranged in the groove by the support member 6, which plays a supporting and guiding role for the movable cover plate 2, making the overall structure of the movable cover plate 2 more stable. Furthermore, the support member 6 is a roller, which can reduce the resistance of the movable cover plate 2 when it moves, and facilitate the opening and closing of the movable cover plate 2. In this embodiment, grooves are provided on both side walls of the cable trench. There are multiple support members 6, which are arranged at the corners of the movable cover plate 2.

[0034] It is worth mentioning that in this embodiment, the driving device 3 is electrically connected to an external electric control device such as an electric control switch, a computer and a central control device, and can directly control the opening and closing of the movable cover 2 through the external electric control device, which is convenient and quick to use. The specific electrical connection method belongs to the conventional technical means in this field, so it will not be described in detail here.

[0035] In summary, the electrically controlled opening and closing cable trench cover of this embodiment cleverly divides the cable trench cover into two parts: a fixed cover 1 and a movable cover 2, and sets an angled structure 4 at the contact position between the fixed cover 1 and the movable cover 2, so that the movable cover 2 can be moved to the bottom of the fixed cover 1 along the inclined direction of the angled structure 4 under the control of the drive device 3, so that the cable trench leaks out. Compared with the traditional manual handling method, the efficiency of opening and closing the cover is greatly improved. At the same time, the structure of the cable trench cover is not complicated, the space occupied is small, and the manufacturing cost and maintenance cost are low.
