DETAILED DESCRIPTION

[0022] Example implementations will now be described more fully with reference to the accompanying drawings. Example implementations can be implemented in any

[0023] The described features, structures, or characteristics can be combined in any suitable manner in one or more implementations. In the following description, numerous specific details are provided to give a thorough understanding of implementations of the application. One skilled in the relevant art will recognize, however, that the

[0024] ​​The following described embodiments are the open type comprehensive pipe gallery feeding port cover device of the present application, and the present application is not limited to the embodiments. All other embodiments obtained by those skilled in the art without creative labor are covered by the scope of the present application.

[0025] Please refer to Figures 1 to 5 According to the embodiments of the present application, an open type comprehensive pipe gallery feeding port cover device is provided, which comprises a cover frame 2, two cover plates 1, a feeding port is formed on the cover frame 2 (approximately at the central position of the cover frame 2), and each of the two cover plates 1 is drivingly connected with a displacement driving assembly. The displacement driving assembly can drive one of the two cover plates 1 to reciprocate linearly along the length direction of the feeding port, so that the two cover plates 1 can move towards each other to block the feeding port or move away from each other to open the feeding port. In the technical solution, the displacement driving assembly drives the two cover plates 1 to move towards each other or away from each other to open or close the feeding port, which does not need to be opened manually. The weight of the cover plate 1 can be made heavier to achieve the purpose of theft prevention and facilitate the maintenance work in the pipe gallery. The open type two cover plates matched with the corresponding displacement driving assemblies are especially suitable for the case where the size of the feeding port is large, which reduces the size of the single cover plate 1, reduces the processing difficulty of the cover plate 1, and is beneficial to the power selection of the related components in the displacement driving assembly, thereby reducing the design cost.

[0026] As a specific embodiment, guide rails 31 are respectively arranged on the cover frames 2 corresponding to the opposite sides of the feeding port, the guide rails 31 extend along the length direction of the feeding port, the cover plates 1 are respectively provided with rollers 11 corresponding to the opposite sides of the feeding port, and the rollers 11 are slidingly connected to the guide rails 31. The sliding direction of the cover plate 1 is guided by the cooperation between the rollers 11 and the guide rails 31, which is simple in structure and easy to implement. As a preferred embodiment, the cross sections of the guide rails 31 and the rollers 11 are T-shaped, which can ensure that the rollers 11 do not derail during sliding, thereby ensuring the reliability and stability of sliding and safety.

[0027] In some embodiments, the guide rails 31 are assembled on the top surface of the cover frame 2, that is, the guide rails 31 can be installed on the top surface of the cover frame 2 in an assembled manner, which reduces the processing difficulty of the cover frame 2. For example, a suitable type of steel (rectangular tube) can be used for welding, without considering the processing of the guide rails 31, and the guide rails 31 are directly purchased as selected parts and installed.

[0028] As mentioned above, the guide rail 31 is installed protruding from the top surface of the cover frame 2, and the cover plate 1 slides on the top surface of the guide rail 31, so that a height difference, i.e. a gap, will be formed between the cover plate 1 and the cover frame 2, and the existence of this gap will cause a sealing defect of the feeding opening. As a preferred embodiment, the guide rail 31 is provided with at least three cover plate falling positioning grooves 32 arranged at intervals along the length direction of the guide rail 31, and the number of the rollers 11 arranged on each side of the cover plate 1 is the same as the number of the cover plate falling positioning grooves 32, and the arrangement positions of the rollers 11 on each side of the cover plate 1 are adapted to the positions of the cover plate falling positioning grooves 32, and at least two rollers are located at the end of the cover plate 1 close to the feeding opening. In this way, when the cover plate 1 is driven to move towards each other, the rollers 11 of the cover plate 1 will fall into the cover plate falling positioning grooves 32 below the top surface of the guide rail 31 one by one at the corresponding positions capable of closing the feeding opening, so that the gap between the cover plate 1 and the cover frame 2 is reduced or even disappears (related to the groove depth design of the cover plate falling positioning grooves 32), and the sealing performance of the feeding opening in the closed state is improved. It needs to be particularly pointed out that the number of the cover plate falling positioning grooves 32 is at least three, and at least two rollers 11 are located at the end of the cover plate 1 close to the feeding opening, which can effectively ensure that the cover plate 1 will not be stuck in the cover plate falling positioning grooves 32 during sliding and simultaneously ensure the position stability (positioning) of the cover plate 1 when completely closing the feeding opening. Specifically, due to the foregoing design of the rollers 11 and the cover plate falling positioning grooves 32 of the present application, when the cover plate 1 at the distal end slides towards the proximal end, if no intermediate roller is arranged between the two rollers 11, the first roller 11 at the proximal end will first fall into the intermediate cover plate falling positioning groove 32 and will be stuck due to the positioning effect of the cover plate falling positioning groove 32, and the cover plate 1 obviously cannot continue to slide to completely close the feeding opening, and since the intermediate roller is arranged between the two rollers 11 in the present application, when the first roller 11 passes through the intermediate cover plate falling positioning groove 32, the intermediate roller is on the top surface of the guide rail 31 to form a horizontal support for the cover plate 1, at this time the first roller 11 will not enter the intermediate cover plate falling positioning groove 32, and all the rollers 11 on the same cover plate 1 will fall into the grooves one by one and form a complete closure of the feeding opening only after corresponding to all the cover plate falling positioning grooves 32. Figure 2

[0029] Referring to Figure 2 or Figure 5 ​As shown, the cover-falling positioning groove 32 comprises a stop groove wall 321 and a guide groove wall 322, the stop groove wall 321 is downstream of the guide groove wall 322 in the direction of the corresponding cover plate 1 moving towards each other, wherein the guide groove wall 322 can guide the roller 11 in the cover-falling positioning groove 32 to the guide rail 31 when the corresponding cover plate 1 moves away. The stop groove wall 321 is perpendicular to the top surface of the cover plate frame 2, thereby preventing the cover plate 1 from continuing to slide forward after the roller 11 falls into the cover-falling positioning groove 32, thereby achieving effective stop of the cover plate 1, while the guide groove wall 322 on the other side can effectively guide the roller 11 in the cover-falling positioning groove 32 during the opening of the cover plate 1, so that the cover plate 1 can be smoothly connected to the top surface of the guide rail 31, thereby achieving smooth opening of the feeding port.

[0030] As a preferred implementation of the displacement driving assembly, the displacement driving assembly comprises a rotating driving component 41 (such as a rotary motor), a driving gear 42, a transmission chain (not shown in the figure), a supporting gear 43, the driving gear 42 and the supporting gear 43 are arranged in a spaced manner along the length direction of the guide rail 31, and the transmission chain is simultaneously tensioned and looped between the driving gear 42 and the supporting gear 43, the rotating driving component 41 drives the driving gear 42 to rotate, and the transmission chain is connected with the cover plate 1, specifically, the transmission chain is connected with one end of the cover plate 1 through the transmission chain connecting piece 12. In this technical solution, the chain transmission is used as the driving mechanism of the sliding of the cover plate 1, when the rotating driving component 41 rotates, the driving gear 42 and the supporting gear 43 realize the loop driving of the transmission chain through the tooth meshing with the transmission chain. The looped transmission chain further drives the linear displacement (dragging) of the cover plate 1 connected therewith, thereby ensuring the position switching of the corresponding cover plate 1.

[0031] In some embodiments, the displacement driving assembly further comprises a driving shaft 44 and a driven shaft 45 which are arranged in a spaced manner on the cover plate frame 2, the rotating driving component 41 drives the driving shaft 44 to rotate, two driving gears 42 are arranged in a spaced manner on the driving shaft 44 along the length direction of the driving shaft 44, two supporting gears 43 are arranged in a spaced manner on the driven shaft 45 along the length direction of the driven shaft 45, the transmission chain has two, and the two transmission chains are respectively tensioned and looped on one of the two driving gears 42 and one of the two supporting gears 43, and the two synchronously rotating transmission chains are respectively connected with the end portions of the cover plate 1, so that the sliding of the cover plate 1 is more stable and smooth. The end of the guide rail 31 away from the feeding port is provided with a limiting structure, which can be a protruding piece assembled on the guide rail 31, or can be a protruding part integrally connected on the guide rail 31 in other ways, so as to limit the displacement of the cover plate 1 during opening.

[0032] As a preferred, the roller 11 is a mute wheel, which can reduce the noise during the position switching of the cover plate 1.

[0033] In some embodiments, the cover plate 1 is further provided with a manual locking device 5, which includes a rotating wheel inside or outside the feeding port. Rotation of the rotating wheel can drive the locking rod connected thereto to exit or enter the corresponding lock port of the cover plate frame 2, thereby achieving manual unlocking and locking of the cover plate 1.

[0034] The working process of the split comprehensive pipe gallery feeding port cover device of the present application will be further described below. Figure 1 The working process of the split comprehensive pipe gallery feeding port cover device of the present application will be further described below.

[0035] When the feeding port needs to be closed, the motor (i.e. the aforementioned rotating driving part 41) is started, the motor drives the transmission shaft (i.e. the aforementioned driving shaft 44) to rotate, the transmission shaft gear (i.e. the aforementioned driving gear 42) on the transmission shaft starts to rotate, drives the transmission chain to perform circular motion, the pulley block (i.e. the roller 11 on the cover plate 1 connected with the transmission chain) connected with the transmission chain starts to move horizontally along the slide rail direction (i.e. moves towards each other) under the traction of the transmission chain, drives the cover plate 1, until the front pulley block (i.e. the roller 11 near the feeding port side) enters the directional slot (i.e. the aforementioned cover plate falling positioning slot 32) and is fixed, the cover plate 1 and the feeding port are closed.

[0036] When the feeding port needs to be opened, the motor is reversed, the corresponding transmission shaft is reversed, the traction of the transmission chain drives the pulley block to move reversely, the front pulley block leaves the directional slot, the cover plate 1 slowly returns to the initial position, the cover plate 1 completely leaves the feeding port, and the feeding port is opened.

[0037] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
