Referring to fig. 1 to 7, a support tool for a shield body of a shield machine includes a base 10, at least one set of support mechanisms 20 disposed on the base 10, and the support mechanisms 20 can reciprocate along a first horizontal direction relative to the base 10, the support mechanisms 20 include a support base 21, two sets of traverse assemblies 22 disposed on two sides of the support base 21, and two sets of support assemblies 23 disposed on the traverse assemblies 22 respectively, the traverse assemblies 22 include a cross beam 221 capable of reciprocating along a second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction, the support assemblies 23 include support shoes 231 mounted on the cross beam 221, and the support shoes 231 can rotate in a vertical direction.

The base 10 is fixed on the floor of the engineering plant, and the supporting mechanism 20 is arranged on the base 10 and can reciprocate along the first horizontal direction. When the shield body 30 is placed on the support tool, it is in contact with the top surface of the support shoe 231, i.e. the support shoe 231 is in direct contact with the support shield body 30. When the shield body 30 is fixed on the supporting factory, the axial direction of the shield body 30 is in the same direction as the first horizontal direction, and the second horizontal direction is in the same direction as the diameter of the shield body 30 in the horizontal direction. The whole supporting tool is of a bilateral symmetry structure.

The shield body 30 is placed on the supporting tool, and the supporting tool is driven to move in the workshop by moving along the first horizontal direction relative to the base 10 through the supporting mechanism 20, so that the position of the auxiliary lifting device for driving in the workshop can be flexibly matched.

Both beams 221 are reciprocable in the second horizontal direction. When the two cross beams 221 move relatively (approach each other), the distance between the two corresponding supporting shoes 231 is also reduced, so that the two supporting shoes 231 can correspondingly support the shield body 30 with smaller diameter; when the two cross beams 221 move back (away from each other), the distance between the corresponding two supporting shoes 231 also becomes larger, so that the two supporting shoes 231 can correspondingly support the shield body 30 with a larger diameter. In addition, the supporting shoe 231 can rotate in the vertical direction, that is, the supporting shoe 231 is turned over in the vertical direction, the angle of the top surface of the supporting shoe 231 (the contact surface of the supporting shoe 231 and the shield body 30) can be adjusted, the diameter of the shield body 30 is different, the radian of the cambered surface of the supporting shoe 231 is different, and the angle of the top surface of the supporting shoe 231 is adjusted, so that the supporting shoe can be better attached to the surface of the shield body 30, and the supporting is firmer.

In this embodiment, the base 10 is provided with at least one sliding rail 11 disposed along the first horizontal direction, and the bottom end of the supporting mechanism 20 is provided with pulleys 12 disposed in one-to-one correspondence with the sliding rails 11.

Specifically, the sliding rail 11 is a steel rail, and the pulley 12 is a steel wheel matched with the steel rail. In order to ensure the stability of the movement of the support mechanism 20 and the shield body 30, the number of the sliding rails 11 is four (specifically, the sliding rails can be designed according to practical requirements, and the number of the corresponding pulleys 12 is also four, the corresponding pulleys are correspondingly matched with the sliding rails 11 one by one, and one group of pulleys 12 comprises two steel wheels. Furthermore, two pulleys 12 are symmetrically arranged at the bottom ends of the supporting seat 21, and one pulley 12 is arranged at the bottom ends of the two traversing assemblies 22, so that the supporting mechanism 20 and the shield body 30 can move more stably.

In this embodiment, the number of the supporting mechanisms 20 is three, and the three supporting mechanisms 20 are sequentially arranged along the first horizontal direction.

The support mechanism 20 is designed into a plurality of groups to disperse stress, so that the support shield body 30 is more stable. The specific number of the supporting mechanisms 20 can be flexibly designed according to the actual length of the shield body 30, and is not limited herein. Further, the multiple groups of supporting mechanisms 20 are sequentially and uniformly arranged along the first horizontal direction, so that the stress on each part of the shield body 30 is more uniformly dispersed, and the support is more stable.

In this embodiment, as shown in fig. 3 to 7, the traversing assembly 22 is designed as follows: the traversing assembly 22 comprises a traversing rail 222 arranged along a second horizontal direction and a traversing cylinder 223 for driving the traversing beam 221 to move, wherein the traversing beam 221 reciprocates along the second direction through the traversing rail 222.

Specifically, the traversing cylinder 223 is disposed along the second horizontal direction, the cylinder body of the traversing cylinder 223 faces to one side of the center of the supporting seat 21, that is, faces to the inner side, and the piston of the traversing cylinder 223 faces to the outer side and is connected with the beam 221, and the piston of the traversing cylinder 223 stretches to drive the beam 221 to reciprocate along the second horizontal direction. The traversing rail 2221 improves the guiding and limiting action for the movement of the beam 221, making its movement smoother.

The traversing rail 222 is structured as follows: the traversing rail 222 includes a guide rail 2221 with an i-shaped cross section, and a guide groove 2222 adapted to the bottom end of the guide rail 2221, the guide rail 2221 reciprocates along a second horizontal direction relative to the guide groove 2222, and the cross beam 221 is fixedly connected with the guide rail 2221.

The guide rail 2221 and the guide groove 2222 are both disposed to extend in the second horizontal direction. The guide groove 2222 is a groove, and its shape is adapted to the bottom end of the guide rail 2221, and the cross section is approximately convex. The bottom end of the guide rail 2221 is correspondingly embedded in the guide rail 2222, and the guide rail 2221 is reciprocally movable in the second horizontal direction with respect to the guide rail 2222. The top end of the guide rail 2221 is locked and fixed with the cross beam 221 through a screw, the cross beam 221 moves under the action of the transverse moving oil cylinder 223, and then the guide rail 2221 is driven to move along the guide groove 2222, and the cooperation of the guide rail 2221 and the guide groove 2222 enables the movement of the cross beam 221 to be more stable.

The design of the beam 221 is as follows: the cross beam 221 is inverted L-shaped, and includes a horizontal portion 2211 and a vertical portion 2212 that are connected to each other, the horizontal portion 2211 is fixedly connected to the upper end of the guide rail 2221, and the vertical portion 2212 is connected to the traversing cylinder 223.

The vertical portion 2212 is located at the outer side end of the beam 221, the vertical portion 2212 is arranged downwards, the inner side of the vertical portion 2212 is fixedly connected with a piston of the traversing cylinder 223, and the traversing cylinder 223 drives the beam 221 to move through a connection position with the vertical portion 2212. The bottom end of the horizontal portion 2211 is fastened and fixed to the top end of the guide rail 2221 by screws.

Further, a nylon pad 224 is disposed between the cross beam 221 and the guide rail 2221. Namely, nylon pads 224 are provided between the bottom surface of the horizontal portion 2211 of the cross beam 221 and the top surface of the guide rail 2221.

As shown in fig. 3 to 5, in the present embodiment, the stay 231 is mounted on the cross beam 221 by the following structure: the bottom end of the supporting shoe 231 is connected with the beam 221 through two adjusting cylinders, and the two adjusting cylinders are sequentially arranged along the second horizontal direction. And the top surface of the supporting shoe 231 is an arc surface, and the bottom end of the supporting shoe 231 is rotatably connected with the adjusting oil cylinder.

Specifically, the adjusting cylinders are all vertically arranged, the rod bodies of the adjusting cylinders are fixed on the cross beam 221, and the pistons are upwards rotatably connected with the bottom ends of the supporting shoes 231. The piston of the adjusting cylinder moves up and down, thereby driving the corresponding position of the supporting shoe 231 to move up and down. And because the number of the adjusting cylinders is two and the adjusting cylinders are arranged along the second horizontal direction, when the piston movements of the two adjusting cylinders are not synchronous (the distances of the up-and-down movements are different or the directions are different or only one piston moves), the supporting shoe 231 can rotate in the vertical direction to adjust the top surface angle of the supporting shoe so as to adapt to the cambered surfaces of the shield bodies 30 with different diameters.

In addition, the piston of the adjusting cylinder moves up and down, the height of the supporting shoe 231 can be adjusted, and the function can be flexibly adjusted according to actual requirements. If the diameter of the shield body 30 is smaller, the height of the supporting shoe 231 can be properly adjusted so as to be better matched with the auxiliary lifting device for the running in the workshop.

Further, the two adjusting cylinders are a first adjusting cylinder 232 located at the inner side and a second adjusting cylinder 233 located at the outer side, a bar-shaped hole 2311 is provided at the bottom end of the supporting shoe 231, and the supporting shoe 231 is rotatably connected with the second adjusting cylinder 233 through the bar-shaped hole 2311.

The adjusting cylinder close to the center of the supporting seat 21 is a first adjusting cylinder 232, correspondingly, the adjusting cylinder far away from the center of the supporting seat 21 is a second adjusting cylinder 233, the top ends of the first adjusting cylinder 232 and the second adjusting cylinder 233 are hinged with the supporting shoe 231, and a bar-shaped hole 2311 is formed at the joint of the corresponding second adjusting cylinder 233 to provide a movement space for the supporting shoe 231 to rotate in the vertical direction (the cylinder bodies of the two adjusting cylinders are fixed).

As shown in fig. 3 to 5, taking the adjustment of the support tool from the small diameter shield body 30 to the large diameter shield body 30 as an example, the adjustment principle of the support tool is described:

the pistons of the two traversing cylinders 223 act to drive the two beams 221 to move back to the two outer sides respectively, so that the distance between the two groups of supporting components 23 (supporting shoes 231) is increased, then the two first adjusting cylinders 232 move upwards, the two second adjusting cylinders 233 move downwards, so that the two supporting shoes 231 rotate in the vertical direction for adjusting the angle, and meanwhile the height of the supporting shoes 231 is also reduced, and therefore, the two supporting shoes 231 can support the shield body 30 with a larger diameter compared with the original state. Specifically, the adjustment amount of each component is adjusted according to actual requirements, and when the support tool is adjusted from being applicable to the large-diameter shield body 30 to being applicable to the small-diameter shield body 30, the adjustment process of the support tool is opposite to the adjustment process.

The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
