Description

Technical Field

[0001] The utility model relates to the technical field of shield machines, in particular to a shield machine debugging stand. Background Art

[0002] The shield machine is a mechanical equipment used for underground tunnel construction. It can efficiently complete the tunnel construction task by drilling holes underground and constructing tunnel lining at the same time. The shield machine debugging bench is a key equipment for debugging and verification after the shield machine is manufactured. During the manufacturing process, the various components and systems of the shield machine need to be assembled and installed. By installing the shield machine on the debugging bench, the operating state of the shield machine in the actual construction environment can be simulated for system debugging and performance verification.

[0003] The Chinese patent with publication number CN217582129U discloses a shield machine debugging bench, which includes a base, a servo motor, a reducer and a support plate. Each group of the reducers is connected to a group of support plates through a group of adjustment structures, which effectively avoids the problem that the fixed straight slot plates cannot effectively support longer or shorter shield machines due to the complex models of shield machines and the different lengths of different shield machines, thereby improving the applicability of the device.

Therefore, it is impossible to effectively adapt to shield machines of different diameters by only replacing the support plates, and the device cannot provide stable support for shield machines of different diameters. Therefore, it is necessary to provide a shield machine debugging stand to solve the above-mentioned technical problems. Utility Model Content

[0029] A shield machine debugging stand, comprising:

[0030] A transverse support frame 1, the number of which is two, a plurality of longitudinal support frames 2 are fixedly installed on the top of the transverse support frame 1, a fixed box 21 is fixedly installed on the front end of the longitudinal support frame 2, a limiting groove 6 is provided on the top of the longitudinal support frame 2, a first threaded rod 5 is rotatably installed inside the limiting groove 6, a left-handed thread is provided on the front side of the outer wall of the first threaded rod 5, a right-handed thread is provided on the rear side of the outer wall of the first threaded rod 5, the front end of the first threaded rod 5 sequentially penetrates the front side of the inner wall of the limiting groove 6 and the back side of the fixed box 21 and extends to the inside of the fixed box 21, a symmetrically distributed movable block 4 is sleeved on the outer wall of the first threaded rod 5, and the movable block 4 is slidably connected to the limiting groove 6, the number of the movable blocks 4 is six, the six movable blocks 4 are divided into two groups, and the tops of the two groups of movable blocks 4 are fixedly installed with movable support frames 3;

[0031] A positioning groove 9 is provided at the top of the movable support frame 3, and a second threaded rod 10 is rotatably installed inside the positioning groove 9. A left-handed thread is provided on one side of the outer wall of the second threaded rod 10, and a right-handed thread is provided on the other side of the outer wall of the second threaded rod 10. A first motor 11 is fixedly installed on one side of the movable support frame 3, and a driving end of the first motor 11 passes through one side of the movable support frame 3 and extends to the inside of the positioning groove 9 and is fixedly connected to one end of the second threaded rod 10;

[0032] The outer wall of the second threaded rod 10 is sleeved with symmetrically distributed adjustment blocks 7, and the adjustment blocks 7 are slidably connected to the positioning grooves 9. A fixing plate 13 is fixedly installed on the top of the adjustment block 7, and a support plate 8 is arranged on the top of the fixing plate 13. A driving mechanism is arranged inside the fixed box 21.

[0033] A slot 15 is provided at the top of the fixing plate 13, a connecting plate 14 is fixedly installed at the bottom of the supporting plate 8, and the connecting plate 14 is snap-fitted with the slot 15, a symmetrically distributed threaded holes 16 are provided on the outer surface of the fixing plate 13, a threaded groove 18 corresponding to the position and number of the threaded holes 16 is provided on the outer surface of the connecting plate 14, the fixing plate 13 is threadedly connected with bolts 17 through the threaded holes 16, and the bolts 17 are threadedly connected to the threaded grooves 18, thereby realizing the detachability of the supporting plate 8 and facilitating the replacement of supporting plates 8 of different specifications.

[0034] In one of the embodiments, the driving mechanism includes a worm 20, and the worm 20 is rotatably installed and located inside the fixed box 21 below the first threaded rod 5. A worm wheel 19 is fixedly installed on the front end outer wall of the first threaded rod 5, and the worm wheel 19 is meshed with the worm 20. A second motor 12 is fixedly installed on one side of the fixed box 21, and the driving end of the second motor 12 passes through one side of the fixed box 21 and extends to the inside of the fixed box 21 and is fixedly connected to one end of the worm 20, thereby achieving the synchronous rotation of multiple first threaded rods 5 by one driving source, reducing the operating cost of the equipment and improving the practicality of the equipment.

[0035] In one of the preferred embodiments, a threaded hole matched with the first threaded rod 5 is opened on the front side of the movable block 4, and the movable block 4 is threadedly connected to the first threaded rod 5 through the threaded hole opened on the front side.

[0036] In one embodiment, a threaded hole matched with the second threaded rod 10 is opened on one side of the adjusting block 7, and the adjusting block 7 is threadedly connected to the second threaded rod 10 through the threaded hole opened on one side.

[0037] In one of the preferred embodiments, the support plate 8 is shaped like an arc-shaped plate, and an anti-skid pad is fixedly installed on the top of the support plate 8. The arc-shaped plate design of the support plate 8 can better adapt to the outer wall of the shield machine, improve the fit between the support plate 8 and the outer wall of the shield machine when they collide, and enhance the support effect. Through the setting of the anti-skid pad, the friction between the support plate 8 and the outer wall of the shield machine is increased, thereby improving the support stability.

[0038] The working principle of the utility model is as follows: the electrical components appearing in the present application are all externally connected to a power supply and a control switch when in use. When the debugging bench is in use, the first motor 11 is controlled by the switch to start working, and the driving end of the first motor 11 drives the second threaded rod 10 to rotate. Through the thread transmission of the left-handed thread and the right-handed thread on the second threaded rod 10, and the sliding relationship between the adjusting block 7 and the positioning groove 9, the two adjusting blocks 7 located on the movable support frame 3 can simultaneously move relative to or oppositely. The movement of the adjusting block 7 drives the fixed plate 13 to move, and the movement of the fixed plate 13 drives the support plate 8 to move. Therefore, the lateral spacing between the two support plates 8 on the movable support frame 3 can be adjusted by the drive of the first motor 11. When the second motor 12 is controlled to start working, the driving end of the second motor 12 drives the worm 20 to rotate, and through the meshing of the worm 20 and the worm wheel 19, the worm wheel 19 drives the first threaded rod 5 to rotate. The thread transmission of the right-hand thread and the right-hand thread, and the sliding relationship between the movable block 4 and the limit groove 6, can make the two movable blocks 4 on the longitudinal support frame 2 move relative to each other or move oppositely at the same time. The movement of the movable block 4 drives the movable support frame 3 to move, so the longitudinal spacing between the two movable support frames 3 can be adjusted. The movable support frame 3 drives the support plate 8 to move through the fixed plate 13. Therefore, when the debugging bench is in use, the first motor 11 and the second motor 12 are driven to achieve a bidirectional adjustment effect of the support plate 8 in the horizontal and longitudinal directions. The position of the support plate can be flexibly adjusted as needed to adapt to shield machines of different lengths and diameters. Compared with adapting to shield machines of different diameters by only replacing the support plate 8, the debugging bench has higher flexibility and versatility. It can stably support and adapt to shield machines of different sizes to meet the different usage needs of users. Whether it is the debugging process or other application scenarios, the debugging bench can provide a more reliable and adaptable support solution.

[0039] When the support plate 8 is in use, the bolt 17 can be tightened by a tool, and the bolt 17 can be removed from the inside of the threaded groove 18 through the threaded connection relationship between the bolt 17 and the threaded hole 16 and the threaded groove 18. After the connecting plate 14 loses the fixing effect of the bolt 17, the connecting plate 14 can be pulled out from the inside of the slot 15 at will. In this way, the support plate 8 is removable, which is convenient for replacing support plates 8 of different diameters. In combination with the longitudinal adjustment of the support plate 8, the shield machine can be supported very stably. The removable structure of the support plate 8 is fixed with bolts, and the fixing strength is high. For the support of large equipment such as the shield machine, its stability is ensured, and the safety during the debugging of the shield machine is improved.

[0040] The above is only an embodiment of the utility model, and the common sense such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model. Any figure mark in the claims should not be regarded as limiting the claims involved.
