Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of manhole covers, and in particular relates to a manhole cover supporting and connecting device. Background Art
[0002] Manhole cover refers to the general term for the cover plate and its fixing accessories installed on the manhole with sealing performance. Manhole cover can be divided into protruding type and embedded type according to whether it is higher than the opening surface after installation.
[0003] In some tanks with relatively high pressure protection requirements, the manhole needs to be filled with thicker refractory materials, which makes the overall weight of the manhole cover heavier. If an automatic weighing hinge device is used on some pipe openings, it will greatly facilitate the process of loading and unloading materials and improve the loading and unloading speed. However, for the manhole cover, the heavy weight is usually more difficult to manually disassemble and assemble, and it requires the assistance of multiple people, and the disassembly and assembly efficiency is low.

[0038] Example
[0039] like Figure 1-4 As shown, the utility model provides a manhole cover supporting and connecting device, wherein the manhole cover is embedded in a manhole seat on a tank body, and the manhole cover supporting and connecting device comprises: a connecting seat, a mounting seat and a connecting assembly.
[0040] The connecting seat is fixed on the surface of the manhole cover, and the connecting seat is fixedly connected to the center of the manhole cover. In order to facilitate the hinge connection with the connecting plate in the connecting assembly, the connecting seat is configured as a strip, and the strip-shaped connecting seat is vertically connected to the manhole cover.
[0041] The mounting seat is arranged on the tank body at one side of the manhole cover in a horizontal direction, that is, the mounting seat and the connecting seat are maintained at approximately the same horizontal height.
[0042] In this embodiment, the connecting assembly includes two connecting plates hinged in sequence. The connecting plates can be arranged to be three or more pieces connected in sequence to facilitate the control of the angle of the end connecting seat. The head and tail ends of the connecting plates are rotated in the vertical direction to form a hinge. One end of the connecting assembly is hinged to the connecting seat, and the other end is hinged to the mounting seat, so that the manhole cover connected to the connecting assembly through the connecting seat can swing freely on the horizontal plane with the mounting seat as the center, wherein the surface of the connecting plate is provided with weight-reducing holes.
[0043] By arranging a mounting seat on the tank body and a connecting seat on the manhole cover, the mounting seat and the connecting seat are connected by a connecting assembly, and the connecting plate in the connecting assembly is vertically rotated to form a hinge. During the process of pulling out and inserting the manhole cover, the connecting device, on the one hand, can play a role in auxiliary support of the manhole cover, reduce the influence of gravity on the manhole cover in the vertical direction, and make it easier for operators to disassemble and assemble the manhole cover. On the other hand, the connecting assembly is hinged through multiple connecting plates to form a multi-link structure, so that the manhole cover installed at the end can present multiple angles compared to the tank body, which is convenient for aligning with the manhole seat. While being supported, the manhole cover can be more flexibly and conveniently matched to the manhole seat.
[0044] Wherein, the connection assembly includes: a first connection plate and a second connection plate.
[0045] The first end of the first connecting plate is hinged to the connecting seat, the first end of the second connecting plate is hinged to the second end of the first connecting plate, and the second end of the second connecting plate is hinged to the mounting seat;
[0046] Specifically, the length of the first connecting plate is greater than the radius of the outer contour of the manhole cover, so that when the connecting plate is hinged to the connecting seat provided on the manhole cover, since the length of the first connecting plate is greater than the outer contour radius of the manhole cover, the second end of the first connecting plate can extend out of the range of the outer contour of the manhole cover and be hinged to the second connecting plate, and the length of the second connecting plate is not less than the distance between the outer end surface of the manhole cover and the mounting seat when it is separated from the manhole seat, such as Figure 2 As shown, at this distance, the manhole cover is separated from the manhole seat and is in a separated state. At this time, the length of the second connecting plate is set to be no less than the distance from the mounting seat to the outer end face of the manhole cover, so that when the manhole cover is separated from the manhole seat, it can be free from the restriction of the connecting assembly.
[0047] The mounting seat comprises: a base and an adjusting seat, and the base and the adjusting seat are connected by a plurality of bolts.
[0048] Specifically, the base is fixed to the surface of the tank body, and a plurality of mounting holes are provided on the base. A plurality of vertical waist-shaped holes corresponding to the mounting holes are opened on the adjustment seat, and the waist-shaped holes correspond to the mounting holes one by one. Since the waist-shaped holes are vertical waist-shaped holes, the adjustment seat can be adjusted in position in the vertical direction. The adjustment seat is connected to the mounting hole through the waist-shaped holes, and is specifically connected and fixed to the mounting hole after the bolt passes through the waist-shaped holes. The connection assembly is hinged to the adjustment seat, and specifically, the second end of the second connection plate in the connection assembly is hinged to the surface of the adjustment seat, and the hinge rotation direction is kept parallel to the hinge rotation direction of the first connection plate and the second connection plate.
[0049] At the same time, the hinged rotation direction of the connecting seat and the first connecting plate remains parallel to the hinged rotation direction of the first connecting plate and the second connecting plate, so that the manhole cover can move freely on the horizontal plane through the connecting assembly and receive support.
[0050] In order to achieve the up and down height adjustment of the adjustment plate, an adjustment plate is arranged at the bottom of the base, and an adjustment screw hole is opened on the adjustment plate, and an adjustment screw is threaded in the adjustment screw hole. After the adjustment screw is threaded in the adjustment screw hole, the end of the adjustment screw abuts against the bottom of the adjustment seat. After the adjustment plate is adjusted to the position vertically through the waist-shaped hole, the bottom of the adjustment plate is tightened by the adjustment bolt to further strengthen the fixation.
[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
