Description

Technical Field

[0001] The utility model relates to the technical field of rail passenger car damping slurry construction, in particular to a rail passenger car damping slurry feeding trough. Background Art

[0002] Damping slurry is a sprayable material based on water-jet synthetic resin. It has vibration reduction, thermal insulation and sealing properties and is widely used in aircraft, communication, vehicles and various machinery industries. At present, in the construction of damping slurry for rail passenger cars, the suction gun needs to be completely immersed in the damping slurry to achieve a full-chamber and full-suction spraying effect. Otherwise, air will be inhaled and the sprayed damping slurry will contain bubbles, affecting the noise reduction function. However, in the actual production process, due to the poor fluidity of the damping slurry in the flat-bottomed trough, in order to ensure that no air is inhaled, after the suction gun inhales a certain amount of damping slurry to form a depression, the operator needs to adjust the suction gun position and move it to the other side of the feed trough. The construction needs to be adjusted multiple times at a time, which slows down the construction progress. In addition, a large amount of high-viscosity damping slurry remains on the inner wall of the feed trough, causing waste.

[0003] Therefore, based on the above technical problems, technicians in this field urgently need to develop a rail passenger car damping slurry supply trough. Utility Model Content

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] See also Figures 1 to 4 As shown;

[0036] A rail passenger car damping slurry supply trough of this embodiment includes:

[0037] A tank body 1, the bottom of which is provided with running wheels 3; and

[0038] An inner tank structure 2 formed inside the tank body 1;

[0039] The inner tank structure 2 is divided into an inner tank first end 201 and an inner tank second end 202 along the length direction of the tank body 1;

[0040] The width of the first end 201 of the inner groove is greater than the width of the second end 202 of the inner groove, and the height of the first end 201 of the inner groove is greater than the height of the second end 202 of the inner groove;

[0041] The inner tank second end 202 is configured as a suction area for damping the slurry suction operation.

[0042] Specifically, the present embodiment discloses a damping slurry feeding tank, which is mainly composed of a tank body 1, and an inner tank structure 2 is arranged inside to store damping slurry; and in order to facilitate the movement of the device, the bottom of the tank body 1 of the present embodiment has a walking wheel 3. In addition, in order to meet the absorption of high-viscosity damping slurry, the present embodiment uses the deadweight of the damping slurry to realize the flow of the damping slurry toward the second end 202 of the inner tank, so that the sucked damping slurry will be immediately filled to the second end 202 of the inner tank under the action of deadweight, avoiding the technical problem of constantly adjusting the absorption position during the absorption operation.

[0043] Preferably, the tank body 1 of the present embodiment is configured as a frustum-shaped structure with a width at one end greater than a width at the other end; the upper end of the inner tank structure 2 is an open structure, and the damping slurry is stored in the inner tank structure 2 .

[0044] Preferably, the tank body 1 of this embodiment includes a tank first end 101 and a tank second end 102;

[0045] The width of the first end 101 of the trough body is 800 mm, the width of the second end 102 of the trough body is 500 mm, the length of the trough body 1 is 1500 mm; and the height of the trough body 1 is 600 mm.

[0046] First, this embodiment further defines the structure of the tank body 1 and the size that can meet the operational requirements. The tank body 1 of this embodiment is formed as a frustum-shaped structure as a whole, and its size can be determined by determining the size of the internal tank structure 2 according to the capacity requirements of the damping slurry actually stored, and finally determining the size of the tank body 1.

[0047] Preferably, the inner groove first end 201 and the inner groove second end 202 of the inner groove structure 2 of this embodiment are arranged perpendicular to the horizontal plane; the bottom of the inner groove structure 2 is the inner groove bottom surface 203; the angle between the inner groove bottom surface 203 and the inner groove first end 201 is 95°; the angle between the inner groove bottom surface 203 and the inner groove second end 202 is 85°. Secondly, the two sides of the inner groove structure 2 of this embodiment are side walls 204; the angle between the side walls 204 and the horizontal plane is 70°.

[0048] This embodiment further defines the corresponding arrangement angles of each surface of the inner groove structure 2, so that it forms a structure in which the first end 201 of the inner groove is wide and shallow, and the second end 202 of the inner groove is narrow and deep, forming a structure with a height difference and each inside has an inclined angle, and the lowest point is concentrated at one point. Under the influence of the damping slurry's own gravity, it has higher fluidity, which prompts the damping slurry of the feed trough to always flow to the narrow and deep second end 202 of the inner groove, ensuring that the full cavity and full suction state can be achieved without adjusting the position of the suction gun during the construction process. In addition, each inside with an inclined angle can effectively reduce the amount of damping slurry residue on the inner wall and save raw materials.

[0049] In the above technical solution, the utility model provides a rail passenger car damping slurry feeding trough, which has the following beneficial effects:

[0050] The feed trough of the utility model enables the damping slurry to flow toward one end under the action of its own weight through the inner trough structure 2 with height difference and width difference, so that the suction gun position does not need to be adjusted during the construction process, and the residual amount on the inner wall is reduced, the construction is convenient, and raw materials are saved.

[0051] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
