Description

Technical Field

[0001] The utility model relates to the technical field of tunnel jumbo, in particular to a plug board used on a tunnel table, specifically a combined plug board convenient for lifting and adjusting. Background Art

[0002] With the development of technology, when a tunnel jumbo is used for tunnel lining construction, polymer plug boards that can be lifted and lowered are now commonly used for plugging, such as Patent CN213039290U and Patent CN218971213U. In these patented technologies, the lifting of the plug board is adjusted by a threaded connection member with the lifting direction being the same as that of the plug board. For example, when the plug board is lifted and lowered vertically, the displacement between the threaded connection members must also be vertical lifting. Due to the structural limitation of the plug board, the vertically lifting threaded connection member can only be arranged between the top plate and the bottom plate of the plug board. During adjustment, the rotation axis of the threaded connection member is perpendicular to the top plate and parallel to the rear side plate (the rear side plate is a panel for plugging that faces the plugging surface and is vertically fixed to the rear side of the top plate). In such a structure, when adjusting with an open-end wrench, the tangent direction of the wrench rotation is always perpendicular to the lifting direction. When operating, a large amount of wrist force is required. Since the number of plug boards used at one time is large, the operator usually feels discomfort in the wrist, and even suffers from wrist strain. Content of the Utility Model

[0003] Aiming at the problems raised in the background art, the purpose of the utility model is to provide a combined plug board convenient for lifting and adjusting. By changing the structure of the connecting member between the top plate and the top plate, an adjusting bolt with an axis basically parallel to the top plate is used to adjust the lifting of the plug board. Since the tangent direction of the bolt screwing is basically parallel to the lifting direction when exerting force, the arm force rather than the wrist force can be maximally utilized, improving the use comfort and avoiding wrist overwork damage to the operator.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A combined plug board convenient for lifting and adjusting, comprising a top seat and a bottom seat. The top seat is composed of a top plate and a rear side plate A located at the lower rear side of the top plate. The bottom seat is composed of a bottom plate and a rear side plate B located at the upper rear side of the bottom plate. The top plate is arranged above the bottom plate. The rear side plate A is in contact with the rear side plate B. A chute and a sliding plate are arranged between the top plate and the bottom plate. The sliding plate is inserted into the chute and is slidably connected with the chute. A connecting member is connected between the top plate and the bottom plate. The connecting member includes:

[0006] A first hinge assembly, including a first hinge arm A, a second hinge arm A, and a third hinge arm A that are sequentially connected in series from top to bottom and are rotationally hinged; the first hinge arm A is rotationally hinged to the top plate, and the third hinge arm A is rotationally hinged to the bottom plate;

[0007] The second articulated assembly includes a first articulated arm B, a second articulated arm B and a third articulated arm B which are connected in series and rotatably articulated from top to bottom; the first articulated arm B is rotatably articulated with the top plate, and the third articulated arm B is rotatably articulated with the bottom plate; the middle part of the second articulated arm B is rotatably articulated with the middle part of the second articulated arm A;

[0008] A first connecting seat is rotatably hinged on the first hinge assembly, and a first threaded hole is provided on the first connecting seat;

[0009] The second connection seat is rotatably hinged on the second hinge assembly and corresponds to the height position of the first connection seat. The second connection seat is provided with a second threaded hole; the thread rotation direction of the second threaded hole is opposite to that of the first threaded hole;

[0010] An adjusting bolt is laterally arranged between the first hinge assembly and the second hinge assembly, and is threadedly connected to the first threaded hole of the first connecting seat and the second threaded hole of the second connecting seat respectively; the adjusting bolt adjusts the overall height of the connecting member by changing the distance between the first connecting seat and the second connecting seat, thereby changing the distance between the top plate and the bottom plate.

[0011] The first articulated arm A and the second articulated arm A are rotatably articulated via a first articulated axis A, and the first connecting seat is connected to the first articulated axis A and is located in front of the first articulated axis A.

[0012] The first articulated arm B and the second articulated arm B are rotatably articulated via a first articulated shaft B, and the second connecting seat is connected to the first articulated shaft B and is located in front of the first articulated shaft B.

[0013] The connecting member also includes a first articulated seat, which is fixedly connected to the top plate. The first articulated arm A and the first articulated arm B are both rotatably articulated with the top plate through the first articulated seat.

[0014] The connecting member also includes a second articulated seat, which is fixedly connected to the base plate. The third articulated arm A and the third articulated arm B are both rotatably articulated with the base plate through the second articulated seat.

[0015] The number of the connecting pieces is two groups, and the two groups of connecting pieces are evenly distributed on the upper surface of the bottom plate.

[0016] The utility model has the following beneficial effects: the one-piece plug plate proposed by the utility model has a tangential direction of the adjusting bolt screwed in a direction basically parallel to the lifting direction when force is applied, which can maximize the use of arm strength rather than wrist strength, improve the comfort during operation, and avoid overwork and damage to the operator's wrist.

The top seat 1 is composed of a top plate 101 and a rear side plate A 102 located at the lower rear side of the top plate 101. The base 2 is composed of a bottom plate 201 and a rear side plate B 202 located at the upper rear side of the bottom plate 201. The top plate 101 is arranged above the bottom plate 201. The rear side plate A 102 is in contact with the rear side plate B 202. A slide groove 3 and a slide plate 4 are provided between the top plate 101 and the bottom plate 201. The slide plate 4 is inserted into the slide groove 3 and is slidably connected to the slide groove 3. A connecting member 5 is connected between the top plate 101 and the bottom plate 201; in an embodiment of the present utility model, the slide plate 4 is integrally formed with the base 2, the slide groove 3 is integrally formed with the top seat 1, and a receiving groove is provided between the slide groove 3 and the rear side plate A 102; of course, in another structure, the slide plate 4 can also be integrally formed with the top seat 1, the slide groove 3 is integrally formed with the base 2, and the receiving groove is provided between the slide groove 3 and the rear side plate B 202; the above structures belong to the prior art.

[0029] In the present utility model, the connecting member 5 includes:

[0030] The first hinge assembly 51 includes a first hinge arm A511, a second hinge arm A512, and a third hinge arm A513 that are sequentially connected in series from top to bottom and are rotationally hinged; the first hinge arm A511 is rotationally hinged to the top plate 101, and the third hinge arm A513 is rotationally hinged to the bottom plate 201;

[0031] The second hinge assembly 52 includes a first hinge arm B521, a second hinge arm B522, and a third hinge arm B523 that are sequentially connected in series from top to bottom and are rotationally hinged; the first hinge arm B521 is rotationally hinged to the top plate 101, and the third hinge arm B523 is rotationally hinged to the bottom plate 201; the middle of the second hinge arm B522 is rotationally hinged to the middle of the second hinge arm A512;

[0032] The first connecting seat 53 is rotationally hinged to the first hinge assembly 51, and a first threaded hole is provided on the first connecting seat 53;

[0033] The second connecting seat 54 is rotationally hinged to the second hinge assembly 52 and corresponds to the first connecting seat 53 in height position, and a second threaded hole is provided on the second connecting seat 54; the thread rotation direction of the second threaded hole is opposite to that of the first threaded hole;

[0034] The adjusting bolt 55 is horizontally arranged between the first hinge assembly 51 and the second hinge assembly 52, and the adjusting bolt 55 is threadedly connected to the first threaded hole of the first connecting seat 53 and the second threaded hole of the second connecting seat 54 respectively; the adjusting bolt 55 adjusts the overall height of the connecting member 5 by changing the distance between the first connecting seat 53 and the second connecting seat 54, thereby changing the distance between the top plate 101 and the bottom plate 201.

[0035] The usage method of the present utility model is as follows: After assembling the present utility model, after the lining formwork of the tunnel jumbo is in place, place the bottom plate 201 of the present utility model on the edge of the lining formwork, with the top plate 101 facing the tunnel surface, and then screw the adjusting bolt 55. The adjusting bolt 55 shortens the distance between the first connecting seat 53 and the second connecting seat 54. At this time, driven by the deformation of the first hinge assembly 51 and the first hinge assembly 52, the height of the connecting member 5 increases, thereby pushing the top plate 101 to rise and making the top plate 101 tightly press against the tunnel surface. At this time, the gap between the lining formwork and the tunnel surface is blocked. When multiple plugging plates are used in combination, all gaps can be blocked.

[0036] The described first articulated arm A511 and the second articulated arm A512 are rotationally hinged through the first hinge shaft A. The first connecting seat 53 is connected to the first hinge shaft A and is located in front of the first hinge shaft A. In an embodiment of the present invention, the first connecting seat 53 and the first hinge shaft A are integrally formed structures. At this time, the first hinge shaft A is a structure that can rotate in the hinge hole, so that the first connecting seat 53 and the first hinge assembly 51 maintain a rotationally hinged relationship; if the first hinge shaft A is a fixed shaft, the first connecting seat 53 should maintain a rotationally hinged connection with the first hinge shaft A.

[0037] The described first articulated arm B521 and the second articulated arm B522 are rotationally hinged through the first hinge shaft B. The second connecting seat 54 is connected to the first hinge shaft B and is located in front of the first hinge shaft B. The structural design of the first hinge shaft B corresponds to that of the first hinge shaft A, and its connection method with the second connecting seat refers to that of the first hinge shaft A and the first connecting seat 53.

[0038] The connecting member 5 further includes a first hinge seat 56. The first hinge seat 56 is fixedly connected to the top plate 101. The first articulated arm A511 and the first articulated arm B521 are both rotationally hinged to the top plate 101 through the first hinge seat 56.

[0039] The connecting member 5 further includes a second hinge seat 57. The second hinge seat 57 is fixedly connected to the bottom plate 201. The third articulated arm A513 and the third articulated arm B523 are both rotationally hinged to the bottom plate 201 through the second hinge seat 57.

[0040] In an embodiment of the present invention, the number of the connecting members 5 is two groups. The two groups of connecting members 5 are evenly distributed on the upper surface of the bottom plate 201 to make the force on the top plate 101 uniform.

[0041] The parts not described in detail in the present invention are prior art.
