Description

Technical Field

[0001] The present application relates to the field of gate valve wells, and in particular to a gate valve well. Background Art

[0002] Pipeline line engineering is the engineering that connects the starting station, intermediate station and terminal station of the pipeline with pipes, pipe fittings, valves, etc. to form the pipeline transportation line. It is the main part of the pipeline engineering. It is the engineering of constructing pipelines for transporting oil, natural gas and solid slurry.

[0003] These include pipeline line projects, station and depot projects, and pipeline ancillary projects. Pipeline projects in a broad sense also include the supply of materials and equipment. Where there are valves, a gate valve well needs to be established to facilitate the control, inspection, and maintenance of the valves.

[0004] Generally, the gate valve well has a straight-through structure. During long-term use, the well cover may be broken, cracked or have holes when it is rolled over by heavy vehicles. When the well cover is damaged, pedestrians may step on the broken well cover or the broken holes on the well cover without paying attention when passing by, and they may easily fall into the well. Utility Model Content

[0005] The purpose of the present application is to solve the problem raised in the above-mentioned background technology that when the manhole cover is damaged, pedestrians may not pay attention and step on the damaged manhole cover or the damaged holes on the manhole cover, which may cause passers-by to miss steps and fall into the well. The present application provides a gate valve well.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A gate valve well comprises a wellway, a valve is installed in the wellway, pipes are installed at both ends of the valve, a well cover is rotatably connected to the wellway, an anti-fall mechanism is arranged between the well cover and the valve, and a clamping mechanism is arranged on the well cover.

[0008] By adopting the above technical solution, the anti-fall mechanism is connected to the manhole cover by a clamping mechanism. When a pedestrian steps on a damaged manhole cover, the pedestrian directly passes through the manhole cover and steps on the anti-fall mechanism. When the manhole cover is used normally and the valve in the shaft needs to be inspected, the manhole cover is directly opened. The manhole cover uses the clamping mechanism to drive the anti-fall mechanism, so that the anti-fall mechanism is opened together with the manhole cover. This can reduce the possibility that after the manhole cover is damaged, pedestrians accidentally step on the manhole cover, causing the manhole cover to collapse, and then fall into the shaft and get injured.

[0009] Furthermore, the anti-fall mechanism includes a support frame arranged in the well, a support plate is fixed on the support frame, a plurality of evenly distributed drainage holes are opened on the support plate, and a support assembly is arranged between the support frame and the inner wall of the well.

[0010] By adopting the above technical solution, the support frame and the support plate are supported in the shaft by the support assembly, so that when pedestrians step on the damaged shaft cover, the support frame and the support plate can be used to support the pedestrians.

[0011] Furthermore, the support assembly includes two support frames symmetrically fixed on the support frame, and a support groove corresponding to the support block is opened on the well, the support groove is open on one side facing the well cover, and one side of the support groove is arc-shaped.

[0012] By adopting the above technical solution, the support block on the support frame is placed in the support groove provided in the well, and the support frame is supported by the support block, so that the installation of the support frame can be facilitated.

[0013] Furthermore, a support pad is fixed on the support plate, and the support pad is a rubber pad. The support pad is provided with a pipe through hole corresponding to the drainage hole.

[0014] By adopting the above technical solution, when pedestrians step on the manhole cover, the pedestrians step directly on the support pad, which can play a buffering role and further protect the pedestrians.

[0015] Furthermore, two symmetrical support bars are fixed in the well, the two support bars are located at the bottom of the support frame, and the support bars are in conflict with the support frame.

[0016] By adopting the above technical solution, the support bar contacts the bottom of the support frame, so that the support bar supports the support frame, thereby improving the stability of the support frame and reducing the possibility of the support blocks on both sides of the support frame not being able to support it properly.

[0017] Furthermore, the clamping mechanism includes two clamping rods symmetrically arranged on the support block, the clamping rods are rotatably connected to the support block, a clamping block is fixed to one end of the clamping rod away from the support block, a clamping groove 1 is provided on the manhole cover, a clamping groove 2 is provided at the bottom of the clamping groove 1, and the clamping groove 2 passes through the manhole cover.

[0018] By adopting the above technical solution, two clamping blocks are passed through the corresponding clamping groove 2, and then the clamping blocks are clamped at the bottom of the clamping groove 1, so as to facilitate the connection between the support block and the manhole cover, and facilitate driving the support frame and the support plate when lifting the manhole cover.

[0019] Furthermore, a spring sheet is arranged between the two clamping rods, the spring sheet is U-shaped, both ends of the spring sheet are fixedly connected to the corresponding two clamping rods, a limiting block is arranged on the side of the clamping rod away from the spring sheet, and the limiting block is fixedly connected to the support block.

[0020] By adopting the above technical solution, when the two clamping blocks pass through the clamping slot 2, the clamping blocks are directly buckled in the clamping slot 1 under the push of the spring sheet, so that the clamping blocks can be conveniently clamped in the clamping slot 2.

[0021] Furthermore, a clamping bevel is provided on the clamping block, and the clamping bevel corresponds to the second clamping groove.

[0022] By adopting the above technical solution, the edge of the second clamping groove squeezes the clamping inclined surface on the clamping block, so that the two clamping blocks are close to each other, thereby making it convenient for the two clamping blocks to pass through the second clamping groove.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. The present application places a support frame into the shaft, allows the support blocks on the support frame to contact the support grooves provided on the inner wall of the shaft, allows the support blocks to support the support frame, and the support frame supports the support plate, and then a layer of support pads is laid on the support plate, and finally the shaft cover is closed. When a pedestrian steps on a damaged shaft cover, the pedestrian's feet directly pass through the shaft cover, and then the pedestrian's feet fall on the support pads, which are then supported by the support plate. The support pads play a buffering role, thereby achieving the purpose of allowing pedestrians to be supported when they step on the damaged shaft cover and reducing the possibility of pedestrians' legs directly entering the shaft and causing falls or falling into the shaft.

[0025] 2. In the present application, when the support frame is placed in the well, the support block on the support frame contacts the support groove opened in the well, and then the manhole cover is covered on the well. When the manhole cover is covered on the well, the two clamping rods on the support block support the clamping block under the action of the limit block and the spring sheet. When the manhole cover is close to the clamping block, the clamping groove 2 approaches the two clamping blocks. When the two clamping blocks completely pass through the clamping grooves, the two clamping blocks are clamped in the clamping groove 1 under the push of the spring sheet. When the manhole cover is lifted, the manhole cover drives the clamping block, the clamping block drives the clamping rod, the clamping rod drives the support block, and the support block drives the support frame to move with the manhole cover, thereby achieving the purpose of allowing the support frame and the support plate to move with the manhole cover when the manhole cover is lifted, thereby facilitating the inspection of the valve in the well.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1 —4 Provide further details of this application.

[0033] The embodiment of the present application discloses a gate valve well.

[0034] Reference Figure 1 , Figure 2 and Figure 3 A gate valve well comprises a well 1, a valve 2 is installed in the well 1, pipes 3 are installed at both ends of the valve 2, a well cover 4 is rotatably connected to the well 1, an anti-fall mechanism 5 is arranged between the well cover 4 and the valve 2, and a clamping mechanism 6 is arranged on the well cover 4.

[0035] After the valve 2 and the pipe 3 in the well 1 are installed, a rotatably connected manhole cover 4 is installed on the well 1, and then the anti-fall mechanism 5 is connected to the manhole cover 4 by the clamping mechanism 6, and then the manhole cover 4 is covered on the well 1. When the manhole cover 4 is damaged after being crushed by passing vehicles for a long time, pedestrians do not notice the damage on the manhole cover 4 when passing by, and then step on the manhole cover 4. When the manhole cover 4 is broken, the pedestrians directly pass through the manhole cover 4 and step on the anti-fall mechanism 5. When the manhole cover 4 is in normal use and the valve 2 in the shaft 1 needs to be inspected, the manhole cover 4 is directly opened, and the manhole cover 4 uses the clamping mechanism 6 to drive the anti-fall mechanism 5, so that the anti-fall mechanism 5 is opened together with the manhole cover 4. By arranging the anti-fall mechanism 5 under the manhole cover 4, when the manhole cover 4 is damaged, pedestrians step on the manhole cover 4 and are then supported by the anti-fall mechanism 5, thereby reducing the possibility that pedestrians accidentally step on the manhole cover 4 after the manhole cover 4 is damaged, causing the manhole cover 4 to collapse, and then fall into the shaft 1 and get injured.

[0036] Reference Figure 2 , Figure 3 and Figure 4 The anti-fall mechanism 5 includes a support frame 51 arranged in the well 1, a support plate 52 is fixed on the support frame 51, a plurality of evenly distributed drainage holes 53 are opened on the support plate 52, and a support assembly 54 is arranged between the support frame 51 and the inner wall of the well 1.

[0037] In addition, the support assembly 54 includes two support frames 51 symmetrically fixed on the support frame 51, and a support groove 542 corresponding to the support block 541 is opened on the well 1. The support groove 542 is open on the side facing the manhole cover 4, and one side of the support groove 542 is arc-shaped.

[0038] Furthermore, a support pad 55 is fixed on the support plate 52 . The support pad 55 is a rubber pad. A pipe through hole corresponding to the drainage hole 53 is formed on the support pad 55 .

[0039] The support frame 51 is placed into the shaft 1, and the support block 541 on the support frame 51 is allowed to contact the support groove 542 opened on the inner wall of the shaft 1, so that the support block 541 supports the support frame 51, and the support frame 51 supports the support plate 52, and then a layer of support pad 55 is laid on the support plate 52, and finally the manhole cover 4 is closed. When a pedestrian steps on the damaged manhole cover 4, the pedestrian's foot directly passes through the manhole cover 4, and then the pedestrian's foot falls on the support pad 55, and is then supported by the support plate 52. The support pad 55 plays a buffering role, and by using the support block 541 to be placed in the support groove 542 in the shaft 1, the support frame 51 and the support plate 52 are supported, so that when a pedestrian steps on the damaged manhole cover 4 and passes through the manhole cover 4, his foot can be supported, thereby reducing the possibility of the pedestrian's legs directly entering the shaft 1 and causing a fall.

[0040] Reference Figure 2 , Figure 3 and Figure 4 Two symmetrical support bars 56 are fixed in the well 1. The two support bars 56 are located at the bottom of the support frame 51, and the support bars 56 are in conflict with the support frame 51. When the two support blocks 541 support the support, the support bars 56 are in conflict with the bottom of the support frame 51, so that the support bars 56 also support the support frame 51. By further supporting the support frame 51 with the support bars 56, the stability of the support frame 51 can be improved, and the possibility that the support blocks 541 on both sides of the support frame 51 are not in place can be reduced.

[0041] Reference Figure 2 , Figure 3 and Figure 4The clamping mechanism 6 includes two clamping rods 61 symmetrically arranged on the support block 541, the clamping rods 61 are rotatably connected to the support block 541, and a clamping block 62 is fixed to one end of the clamping rod 61 away from the support block 541. A clamping groove 1 63 is provided on the manhole cover 4, and a clamping groove 2 64 is provided at the bottom of the clamping groove 1 63, and the clamping groove 2 64 runs through the manhole cover 4.

[0042] In addition, a spring sheet 65 is arranged between the two clamping rods 61. The spring sheet 65 is U-shaped. Both ends of the spring sheet 65 are fixedly connected to the corresponding two clamping rods 61. A limiting block is arranged on the side of the clamping rod 61 away from the spring sheet 65. The limiting block is fixedly connected to the support block 541.

[0043] Furthermore, a clamping inclined surface 66 is formed on the clamping block 62 , and the clamping inclined surface 66 corresponds to the second clamping groove 64 .

[0044] When the support frame 51 is placed in the well 1, the support block 541 on the support frame 51 contacts the support groove 542 opened on the well 1, and then the manhole cover 4 is covered on the well 1. When the manhole cover 4 is covered on the well 1, the two clamping rods 61 on the support block 541 support the clamping block 62 under the action of the limit block and the spring sheet 65. When the well cover 4 is close to the clamping block 62, the second clamping groove 64 approaches the two clamping blocks 62, and then the edge of the second clamping groove 64 squeezes the clamping inclined surface 66 on the clamping block 62, so that the two clamping blocks 62 are close to each other, and then the clamping block 62 drives the clamping rod 61, and the two clamping rods 61 squeeze the spring sheet 65. After the two clamping blocks 62 completely pass through the clamping grooves, the two clamping blocks 62 are clamped in the clamping grooves 63 under the push of the spring sheet 65, so that the support block 541 is connected to the manhole cover 4. When the manhole cover 4 is lifted, the manhole cover 4 drives the clamping block 62, the clamping block 62 drives the clamping rod 61, the clamping rod 61 drives the support block 541, and the support block 541 drives the support frame 51 to move with the manhole cover 4. By using the clamping block 62 and the clamping rod 61 to connect the support block 541 with the manhole cover 4, when the manhole cover 4 is lifted, the support frame 51 and the support plate 52 can move with the manhole cover 4, so that the valve 2 in the shaft 1 can be easily inspected.

[0045] Working principle: After installing the valve 2 and the pipe 3 in the well 1, install the rotatably connected manhole cover 4 on the mouth of the well 1. When the support frame 51 is placed in the well 1, the support block 541 on the support frame 51 contacts the support groove 542 opened in the well 1. Then, the corresponding support pad 55 is laid on the support plate 52, and then the manhole cover 4 is covered on the well 1. When the manhole cover 4 is covered on the well 1, the two clamping rods 61 on the support block 541 support the clamping block 62 under the action of the limit block and the spring sheet 65. When the manhole cover 4 is close to the clamping block 62, the clamping groove 64 approaches the two clamping blocks 62, and then the edge of the clamping groove 64 squeezes the clamping slope 66 on the clamping block 62, so that the two clamping blocks 62 are close to each other. Then the clamping block 62 drives the clamping rod 61, and the two clamping rods 61 squeeze the spring sheet 65. When the two clamping blocks 62 completely pass through the clamping grooves, the two clamping blocks 62 are clamped in the clamping groove 63 under the push of the spring sheet 65, so that the support block 541 is connected to the manhole cover 4. When the manhole cover 4 is lifted, the manhole cover 4 drives the clamping block 62, the clamping block 62 drives the clamping rod 61, the clamping rod 61 drives the support block 541, and the support block 541 drives the support frame 51 to move with the manhole cover 4. When the manhole cover 4 is damaged, when pedestrians step on it while walking, the pedestrians' feet directly pass through the manhole cover 4, and then the pedestrians' feet fall on the support pad 55, and then are supported by the support plate 52. The support pad 55 plays a buffering role and plays a role in preventing people from falling.
