The embodiment described in the following example is an underground integrated pipe gallery feeding port cover device of the present invention. This example is only a part of the embodiment of the present invention, but the protection scope of the present invention is not limited to this. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall be included within the protection scope of the present invention.

Referring to FIGS. 1 to 3 , according to an embodiment of the present invention, an underground integrated pipe gallery feeding port cover device is provided, including a cover plate 1 and a cover plate frame 2 , and a feeding port is formed on the cover plate frame 2 . The cover plate 1 has a first position that can block the feeding port and a second position that can allow people or objects to pass through the feeding port. The feeding port cover device of the present invention further includes a jacking assembly. The jacking assembly can exert force on the preset area of the cover plate 1 to form an inclination angle between the cover plate 1 and the cover plate frame 2, so that the cover plate 1 can be switched from the first position to the second position under the action of its own weight . In this technical solution, an inclination angle is formed between the cover plate 1 and the cover plate frame 2 through the jacking assembly, so that the cover plate 1 on the cover plate frame 2 can use its own gravitational potential energy to move from the first position to the second position. The second position, that is, opening the feeding port, greatly facilitates the opening of the cover plate 1 . Especially when the weight of the cover plate 1 is relatively large, the technical solution of the present application can easily open the cover plate 1 with only a small mechanical energy of the jacking assembly, which is simple and easy to operate and saves energy. It can be understood that the inclination angle between the cover plate 1 and the cover plate frame 2 lifted by the jacking assembly does not need to be too large. Generally, about 10° can ensure that the cover plate 1 overcomes its own static friction and opens the feeding port.

The above-mentioned preset area can theoretically be any area that can form an inclination angle between the cover plate 1 and the cover plate frame 2 . Specifically, as shown in FIG. 1 , the preset area may be an area on the bottom surface of the cover plate 1 and adjacent to the side of the first long side of the cover plate 1 , and the number of this area is the same as that of the jacking screw 52 of the jacking assembly. The numbers are equal, and the first long side is the side of the cover plate 1 away from the telescopic drive device 4 . In some embodiments, the cover frame 2 has two side beams 21 that are relatively parallel and spaced apart, and two parallel and spaced cross beams that are perpendicular to the two side beams 21 . The two cross beams and the two side beams 21 together form a feeding port and form a carrier for assembling various components. As a specific embodiment, guide rails 31 are respectively provided on the top surfaces of the two side beams 21 , and rollers 32 are respectively provided on the two sides corresponding to the cover plate 1 and the cover plate frame 2 , and the rollers 32 slide between the guide rails 31 . connection, the structure is simple, and the manufacturing cost is also low. In order to ensure the reliable and stable guiding and sliding of the guide rail 31 to the roller 32, the cross section of the guide rail 31 is designed as a T-shaped structure, and the cross section of the roller 32 also has a corresponding T-slot structure, so as to ensure that the roller 32 does not detach from the guide rail during the sliding process. 31. The roller 32 is preferably a silent wheel, which can reduce the noise generated by the opening and closing of the cover plate 1 .

In order to make it easier for the operator to switch the cover plate 1 from the second position to the first position. In a specific embodiment, one end of the guide rail 31 is provided with a telescopic drive device 4, and the telescopic drive device 4 can exert force on the cover plate 1 to switch the cover plate 1 from the second position to the first position. The telescopic drive device 4 may be, for example, a component capable of generating telescopic linear displacement, such as a hydraulic cylinder and an air cylinder. Preferably, the telescopic drive device 4 is an electric push rod, which can facilitate installation and control. It is worth noting that while the telescopic drive device 4 realizes its closing function of closing the cover plate 1, it is arranged at one end of the guide rail 31 and can also realize the opening of the cover plate 1 (that is, switching from the first position to the second position). Two positions) stroke limit effect.

In some embodiments, the other end of the guide rail 31 has a limit structure 311 , which can effectively limit the extension stroke of the telescopic drive device 4 , and the limit structure 311 can be assembled on the other end of the guide rail 31 by using a separate convex stop member superior. As another better implementation, the limiting structure 311 is the bending portion of the other end of the guide rail 31 , that is, the limiting structure 311 is realized by bending the other end of the guide rail 31 , and the structure is simpler.

In some embodiments, the jacking assembly includes a rotary drive device 51 (specifically, a rotary motor) and a jacking screw 52 . The rotary drive device 51 can drive the jacking screw 52 to rotate in forward and reverse directions. At least two jacking screws 52 are provided, and the at least two jacking screws 52 are respectively located at the other ends of the two guide rails 31 . Specifically, the guide rail 31 can be welded to the rotatable top cover of the jacking screw 52, for example, to ensure the positional stability of the guide rail 31 and the jacking screw 52, and the other end of the guide rail 31 can be hinged with the side beam 21, Therefore, the stability of the position of the guide rail 31 during the process of being lifted and inclined is ensured. The jacking screw 52 is driven up and down by means of a thread. Since the thread has a self-locking angle, the inclination angle of the cover plate 1 can be reliably maintained at the target position.

In the case where the weight of the cover plate 1 is relatively large, a plurality of jacking screws 52 can be provided corresponding to each guide rail 31 at this time, and the plurality of jacking screws 52 are arranged at intervals along the length direction of the guide rail 31, so that a plurality of jacking screws 52 can pass through the guide rails 31. The joint action of the lifting screw 52 ensures smooth lifting. Each jacking screw 52 can also be smaller in terms of power selection and smaller in volume, which saves the space occupied by the device. Specifically, the two adjacent jacking screws 52 are connected by a first transmission shaft 53 ; the rotary output end of the rotary drive device 51 is connected to one of the plurality of jacking screws 52 corresponding to the two guide rails 31 respectively. The second transmission shaft 54 is used for transmission connection between them, so that only one rotary drive device 51 can be used to drive the lifting and lowering of the plurality of jacking screws 52 at the same time, so as to ensure the synchronization.

In some embodiments, the side beam 21 is a hollow structure, a plurality of jacking screws 52 are arranged in the hollow structure, and the rotating moving parts are arranged in the hollow structure, which can make the structure of the device more compact, and can also prevent the operator from accidentally touching resulting in safety hazards.

The cover plate 1 is also provided with a manual locking structure, through which the cover plate 1 can be placed in the first position more reliably and stably. The manual locking structure includes a handwheel 61 , a bolt fixing block (not shown in the figure), and a transmission link 62 connected between the handwheel 61 and the bolt fixing block. When the operator twists the hand wheel 61, the hand wheel 61 will apply a corresponding torque to the transmission link 62, and the transmission link 62 further drives the bolt fixing block to be inserted into the corresponding groove of the side beam 21 to realize the cover plate 1 Mechanical locking with cover frame 2. When the operator rotates the hand wheel 61 in the opposite direction, the bolt fixing block is released from the groove, and the mechanical unlocking between the cover plate 1 and the cover plate frame 2 is realized. The bolt fixing block is preferably made of high-strength material, which can enhance the locking strength and achieve better anti-shock and anti-explosion performance of the cover plate and the feeding port. There are two handwheels 61 , which are located on the top surface and the bottom surface of the cover plate 1 respectively. The two handwheels 61 are coaxially connected to ensure that the operator can achieve mechanical locking and mechanical unlocking from the inside and outside of the feeding port.

The specific working process of the underground integrated pipe gallery feeding port cover device of the present invention is further described below with reference to FIGS. 1 to 3 .

The state shown in FIG. 1 is a state in which the cover plate 1 is in the first position, that is, a state in which the feeding port is blocked. When the feeding port needs to be opened, the motor (that is, a specific implementation of the aforementioned rotary drive device 51 , the same below) is controlled to run (the rotation direction can be set as forward rotation), and the motor drives the two second transmission shafts 54 rotate. The rotating second transmission rod 54 is further rotated via the first transmission shaft 53 and finally drives the jacking screw 52 to rotate. The jacking screw 52 protrudes upward to jack up the guide rail 31 (the cover plate 1 is at the top of the guide rail 31 ), and one end of the guide rail 31 is raised and forms an inclination angle with the ground. At this time, due to the weight of the cover plate 1, under the action of gravitational potential energy, the cover plate 1 slowly slides horizontally and horizontally (sliding toward the side close to the telescopic drive device 4) until it collides with the telescopic drive device 4, and the feeding port is completely opened. That is, the cover plate 1 at this time is in the second position. At this time, the operator can carry out construction operations through the open feeding port.

When the feeding port needs to be closed after construction, the motor is controlled to rotate in the reverse direction, the jacking screw 52 is retracted downward, and the guide rail 31 is restored from the previous inclined state to the horizontal state. At this time, the telescopic drive device 4 is controlled to operate, and its telescopic rod extends and pushes the cover plate 1 to slide toward the other end of the guide rail 31 until it abuts against the limiting structure 311 on the guide rail 31, and the cover plate 1 is switched from the second position to the first position. At this time, the operator twists the handwheel 61, and the screwing force is transmitted to the bolt fixing block through the transmission link 62, and the bolt fixing block is inserted into the groove of the corresponding side beam 21 to achieve mechanical locking.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
