Description

Technical Field

[0001] The utility model relates to the technical field of pipe gallery installation, in particular to a docking mechanism which is convenient for splicing square pipe galleries. Background Art

[0002] A pipe gallery is a building structure used for the centralized laying of large-scale pipelines. It usually adopts an "open"-shaped design and consists of steel structures or reinforced concrete structures such as columns, beams and trusses. Depending on different needs, it can be passable or non-passable, above ground or underground, etc. It has the advantages of fast and convenient construction, good stress-bearing performance and performance.

[0003] Most of the existing pipe corridor connection methods use a socket connection. In this connection method, rubber rings are placed on the socket ends of the pipe corridor and are firmly bonded to the socket with glue to ensure that the rubber rings are fixed and do not shift after the pipe corridors are connected, and form a certain degree of extrusion and water stop with the socket end. However, this socket fixing method relying on glue bonding may cause the distance between the pipe corridors to gradually increase with the migration and flow of sand in the long term. Based on this, a docking mechanism that is more secure between pipe corridors and convenient for splicing square pipe corridors is proposed. Utility Model Content

[0004] In order to solve the technical problem of splicing pipe corridors, the utility model provides a docking mechanism which is convenient for splicing square pipe corridors.

[0005] The utility model is implemented by the following technical solutions: a docking mechanism that is convenient for splicing square pipe galleries, including a pipe gallery main body, an inner sealing frame fixedly connected to the port surface on one side of the pipe gallery main body, a plurality of slots are provided on the three side surfaces of the inner sealing frame, an outer sealing frame fixedly connected to the port surface on the other side of the pipe gallery main body, the outer sealing frame of the previous pipe gallery is matched with the inner sealing frame of the next pipe gallery, and a connector mechanism for fixing adjacent pipe galleries is provided on the inner side of each of the slots.

[0006] As a further improvement of the above-mentioned solution, the connecting member mechanism includes a plurality of clamping rods fixedly connected to the three inner side surfaces of the outer sealing frame, each of the clamping rods is paired with the inner side of each of the clamping slots, and the three inner sides of the inner sealing frame are respectively provided with a caliper mechanism for clamping and fixing the clamping rods entering the clamping slots.

[0007] As a further improvement of the above solution, the caliper mechanism includes multiple calipers arranged in cooperation with multiple clamping rods, one side of the multiple calipers is commonly fixedly connected with a push plate, and a dovetail slider mechanism for limiting the push plate is provided on the side of the pipe gallery body close to the push plate.

[0008] As a further improvement of the above scheme, the dovetail slider mechanism includes a dovetail groove opened on the side of the push plate close to the pipe gallery body, and the inner side of the dovetail groove is slidably connected to a dovetail platform. The push plate is provided with an elastic reset mechanism that enables the push plate to move back and forth left and right along the dovetail platform.

[0009] As a further improvement of the above solution, the elastic reset mechanism includes a limiting groove opened on each of the push plates, and a pull rod mechanism is provided in the limiting groove to ensure that the push plate always stays at a specific position inside the inner sealing frame.

[0010] As a further improvement of the above solution, the pull rod mechanism includes a pull rod slidably connected to the inner side of the limit groove, one end of the pull rod is fixedly connected to the inner sealing frame, and one end of the pull rod is provided with an elastic component for resetting the caliper.

[0011] As a further improvement of the above solution, the elastic component includes a fixing plate fixedly connected to one side of the push plate, and a spring is provided between the fixing plate and one end of the pull rod.

[0012] As a further improvement of the above solution, when the caliper is in the initial position, the spring is in a freely extended state, and the caliper clamps and fixes the clamping rod;

[0013] When the caliper moves from the initial position to a critical position to one side, the push plate moves to one side along the dovetail platform, the spring is in a deformed and stretched state, the caliper opens, and the clamping rod is in a releasable state;

[0014] When the caliper returns to the initial position from the critical position, the push plate moves in the opposite direction along the dovetail platform, the spring rebounds, and the caliper is reset.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model cooperates with the clamping rod through the caliper mechanism that can move left and right. When two pipe corridors need to be spliced, it is only necessary to move the clamping rod and the caliper close to each other and clamp the clamping rod into the slot. The caliper automatically rebounds under the action of the spring to realize the clamping and limiting effect of the caliper on the clamping rod. When the spliced ​​pipe corridor group is buried underground as a whole, even if geological phenomena such as soil loss and movement occur in the long term, the pipe corridor group can maintain a good splicing state under the clamping effect of the caliper on the clamping rod.

[0017] 2. The utility model seals the joints of two adjacent pipe galleries by setting an inner sealing frame and an outer sealing frame, which has a better sealing effect. In addition, sealant can be injected into the space after the inner sealing frame and the outer sealing frame are combined to further improve the sealing performance.

[0025] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example:

[0027] Please combine Figure 1-Figure 5 , a docking mechanism for facilitating the splicing of square pipe galleries in this embodiment includes a pipe gallery main body 1. In this embodiment, the pipe gallery main body 1 is a rectangular structure, the main frame part is made of concrete, and the connecting pieces at both ends are connected by steel structures. An inner sealing frame 2 is fixedly connected to the end surface of one side of the pipe gallery main body 1, and three card slots 4 are provided on the three sides of the inner sealing frame 2. Considering that working space needs to be left inside the pipe gallery, no connecting piece is provided on the lower side. An outer sealing frame 9 is fixedly connected to the end surface of the other side of the pipe gallery main body 1. The outer sealing frame 9 of the previous pipe gallery is matched with the inner sealing frame 2 of the next pipe gallery, and a connecting piece mechanism for fixing the adjacent pipe gallery is provided on the inner side of each card slot 4.

[0028] It should be noted that the size of the outer sealing frame 9 needs to meet the design requirements of the inner sealing frame 2, and the two can be seamlessly connected and smoothly transitioned after being combined.

[0029] Please combine Figure 4As shown, the connecting member mechanism includes three clamping rods 8 fixedly connected to the three inner side surfaces of the outer sealing frame 9, each clamping rod 8 is paired with the inner side of each clamping slot 4, and the three inner sides of the inner sealing frame 2 are respectively provided with a caliper mechanism for clamping and fixing the clamping rod 8 entering the clamping slot 4.

[0030] Please combine Figure 4 As shown, the caliper mechanism includes three calipers 5 arranged in cooperation with three clamping rods 8. It should be noted that the structure of the caliper 5 nozzle is an inclined wedge structure. The width of the caliper 5 nozzle is equal to the slot width of the slot 4. The maximum distance that the caliper 5 nozzle can move to one side is the slot width length of the slot 4, and the slot width length is less than the distance between the two slots 4. One side of the three calipers 5 is commonly fixedly connected with a push plate 6, and a dovetail slider mechanism for limiting the push plate 6 is provided on the side of the pipeline corridor body 1 close to the push plate 6.

[0031] Please combine Figure 4 As shown, the dovetail slider mechanism includes a dovetail groove 13 opened on the side of the push plate 6 close to the pipe gallery body 1, and the inner side of the dovetail groove 13 is slidably connected to the dovetail platform 11. The push plate 6 is provided with an elastic reset mechanism that enables the push plate 6 to move back and forth left and right along the dovetail platform 11.

[0032] Please combine Figure 4 As shown, the elastic reset mechanism includes a limiting groove 7 opened on each push plate 6 , and a pull rod mechanism is provided in the limiting groove 7 to make the push plate 6 always stay at a specific position inside the inner sealing frame 2 .

[0033] Please combine Figure 5 As shown, the pull rod mechanism includes a pull rod 12 slidably connected to the inner side of the limiting groove 7 , one end of the pull rod 12 is fixedly connected to the inner sealing frame 2 , and one end of the pull rod 12 is provided with an elastic component for resetting the caliper 5 .

[0034] Please combine Figure 5 As shown, the elastic component includes a fixed plate 10 fixedly connected to one side of the push plate 6, and a spring 3 is arranged between the fixed plate 10 and one end of the pull rod 12. By setting the spring 3, it can be ensured that when the clamping rod 8 enters the clamping slot 4, the caliper 5 can automatically rebound and lock.

[0035] When the caliper 5 is in the initial position, the spring 3 is in a freely extended state, and the caliper 5 clamps and fixes the clamping rod 8;

[0036] When the caliper 5 moves from its initial position to a critical position to one side, the push plate 6 moves to one side along the dovetail platform 11, the spring 3 is in a deformed and stretched state, the caliper 5 opens, and the clamping rod 8 is in a releasable state;

[0037] When the caliper 5 returns to the initial position from the critical position, the push plate 6 moves in the opposite direction along the dovetail platform 11, the spring 3 rebounds, and the caliper 5 is reset.

[0038] The implementation principle of a docking mechanism that is convenient for splicing square pipe galleries in the embodiment of the present application is as follows: the splicing process of any two pipe galleries in the square pipe gallery group is interpreted here. When the staff needs to assemble a pipe gallery body 1 into the pipe gallery group, they first align the ports of the inner sealing frame 2 and the outer sealing frame 9, and then use the lifting equipment to move the pipe gallery body 1 of the outer sealing frame 9 toward the pipe gallery body 1 of the inner sealing frame 2. At this time, the clamping rod 8 on the inner side of the outer sealing frame 9 is abutted and squeezed against the side of the caliper 5 along the channel of the clamping groove 4. Due to the special inclined structure of the clamping mouth of the caliper 5, the push plate 6 is pushed to slide to one side along the dovetail platform 11, and the clamping mouth of the caliper 5 is offset to one side. The spring 3 is deformed and stretched, and the pull rod 12 slides relatively along the limit groove 7 until the clamping rod 8 enters the bottom of the clamping groove 4. At this time, the spring 3 rebounds, and the clamping mouth of the caliper 5 clamps the clamping rod 8. In this way, the assembly of multiple pipe galleries can be quickly achieved.

[0039] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
