Detailed Description

As shown in fig. 1, the present invention includes beam bodies 1, an expansion joint disposed between two beam bodies 1, and side walls 2 disposed at both sides of the beam bodies 1 in the width direction, wherein an elastic body 3 is filled in the expansion joint, water-retaining bosses 5 corresponding to both ends of the elastic body 3 are disposed on the side walls 2, the bottom surfaces of the water-retaining bosses 5 are lower than the upper surface of the beam bodies 1, inclined drain pipes 4 are disposed on the water-retaining bosses 5, and the drain pipes 4 may be disposed at the end portions of the elastic body 3 or between the water-retaining bosses 5 and the elastic body 3. A drainage system is formed by the water-retaining boss 5, the elastic body 3 and the drainage pipe 5 and is used for draining water on the beam body 1.

The condition that debris blockked up can inevitably appear in drain pipe 4 in the in-service use process, influences normal drainage effect, just needs to carry out artifical mediation this moment. When dredging, the simplest tool is to insert the rod into the drain pipe 4 to push out the sundries in the drain pipe. However, in some cases, stones are piled up and blocked in the drain pipe 4, so that the drain pipe can be smoothly dredged by applying a large force, or sundries are stained on the inner wall of the drain pipe 4, and a great deal of inconvenience is caused when the drain pipe is cleaned by using a simple rod. Therefore, this patent still provides a pressure type pipeline pull throughs 6 that can form a complete set and use, can the one-hand operation. The pressure type pipeline dredging device adopts the existing pressure type pipeline dredging device for the closestool, which is the prior art, and the utility model is not described again.

The utility model provides a quick-connection sealing structure for connecting a pressure type pipeline dredging device 6 with a drain pipe 4, as shown in attached figures 2 and 3, the quick-connection sealing structure comprises an inverted triangular annular clamping groove 9 arranged on the side wall of the drain pipe 4 and a rubber sealing block 8 which is arranged on the outer wall side of an air outlet 7 and is in an inverted frustum shape, the size of the rubber sealing block 8 is slightly smaller than that of the annular clamping groove 9, but the top surface diameter of the rubber sealing block 8 is larger than the inner diameter of the drain pipe 4, on one hand, the matching can be ensured, on the other hand, when the pressure type pipeline dredging device 6 is disassembled, the pressure type pipeline dredging device 6 can be inclined towards one side, so that the pressure type pipeline dredging device and the axis of the drain pipe 6 form a certain angle, and one side of the rubber sealing block 8 can be separated from the annular clamping groove 9, so that the pressure type pipeline dredging device and the drain pipe can be disassembled quickly.

According to the utility model, the inverted-triangular annular clamping groove 9 and the inverted-frustum-shaped rubber sealing block 8 are skillfully adopted, when the pressure of the pressure type pipeline dredging device 6 is released, the pressure type pipeline dredging device 6 moves upwards under the pushing of the reaction force, the top surface of the rubber sealing block 8 is in contact with the top surface of the annular clamping groove 9, and the rubber sealing block is sealed under the action of the pushing force. Meanwhile, the water outlet pipe 6 can be pulled outwards along the axial direction thereof by manpower to realize sealing.

In order to further improve the connection leakproofness between annular joint groove 9 and the sealed piece 8 of rubber be equipped with the annular arch 10 that adopts the rubber material on the top surface of annular joint groove 9, be equipped with on the top surface of the sealed piece 8 of rubber with the protruding 10 matched with bulge loop 11 of annular, bulge loop 11 also adopts the rubber material, and annular arch 10 and bulge loop 11 all adopt the rubber material, can extrude after the atress, further improve and connect sealing performance.

As a further improvement of the utility model, as shown in the attached figures 4 and 5, in the width direction of the beam body, namely the left and right directions of the travelling crane, the middle part of the elastic body is upwards protruded, water can be discharged from the middle part to two sides, and directional water discharge is realized. The elastic body can be inclined to one side to form a single slope, so that water can be drained to one side of the beam body.
