Description

Technical Field

[0001] The utility model relates to the technical field of supports, and in particular to a high-stability support. Background Art

[0002] At present, in order to facilitate the maintenance of tunnel boring machines, most tunnel boring machines are equipped with a support at the end. The support rotates with the help of the driving force of the hydraulic cylinder, thereby abutting against the ground and other contact surfaces to achieve the function of lifting the tunnel boring machine.

[0003] In actual use, people have found that when the tunnel boring machine is working, the shaking of the machine body can be reduced by contacting the support with the ground, thereby improving the stability of the tunnel boring machine; but as the tunnel boring machine starts to work, the vibration force generated during the tunneling process will be transmitted along the machine body to the support, and the support will continue to rub against the ground with which it contacts under the influence of this vibration force. Over time, the bottom of the support will be damaged by friction, thereby destroying the structure of the support itself. When it bears weight or external impact, it is more likely to deform, affecting the normal use of the support. Utility Model Content

[0008] Furthermore, each of the first wear-resistant column, the second wear-resistant column, and the third wear-resistant column has a rotating part that is convenient for disassembly and assembly thereof.

[0009] Furthermore, a plurality of buffer bodies are provided at one end of the base plate close to the connecting ear seat, each of the buffer bodies corresponds to each connecting hole one by one, the buffer body includes a buffer cavity and a buffer member, the buffer cavity is connected to the connecting hole, the buffer member is fixedly arranged inside the buffer cavity and abuts against the first wear-resistant column or the second wear-resistant column or the third wear-resistant column.

[0010] Furthermore, each of the first wear-resistant column, the second wear-resistant column, and the third wear-resistant column has a connecting groove for the limit rod to penetrate, and each of the limit rods is provided with a limit plate at both ends, and each of the limit plates is detachably connected to the limit rod.

[0011] Furthermore, the longitudinal section of the limiting rod is a rectangular structure.

[0012] Furthermore, the ends of the first wear-resistant column, the second wear-resistant column, and the third wear-resistant column away from the bottom plate are all inverted conical structures.

[0013] Furthermore, the connector includes a plurality of connecting plates and a reinforcing frame, and the connecting plates are symmetrically and evenly distributed around the reinforcing frame.

[0014] The working principle and beneficial effects of the utility model are:

[0015] 1. In the present invention, a plurality of wear-resistant components are arranged at the bottom of the base plate as the bottom of the support, and the wear-resistant components are used to replace the bottom of the base plate in contact with the contact surface such as the ground, thereby replacing the wear of the bottom of the base plate, and avoiding the stability of the support itself being affected by the damage to the structure of the base plate itself; the wear-resistant components are arranged in sequence along the linear direction, so that the bottom of the base plate has a plurality of contact points that can contact the ground, thereby ensuring the force balance of the present invention in the working state.

[0016] 2. Each wear-resistant assembly in the utility model includes a first wear-resistant column, a second wear-resistant column, a third wear-resistant column, and a limit rod.

[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] like Figure 1 to Figure 3 As shown, this embodiment proposes a high-stability support, which mainly includes a base plate 1 and a connector 2. The connector 2 is fixedly connected to the base plate 1, and the connector 2 has a rotating drum for rotationally connecting to the tunnel boring machine. The base plate 1 has a connecting ear seat 11, and the connecting ear seat 11 has a connecting hole for connection to a hydraulic cylinder, so that under the action of the hydraulic cylinder, the present embodiment rotates around the rotating drum as the center, thereby abutting against the ground, so that the present embodiment enters a working state.

[0030] The connecting body 2 includes a plurality of connecting plates 21 and a reinforcing frame 22. The reinforcing frame 22 and both ends of each connecting plate 21 are fixedly connected to the rotating drum and the base plate 1 respectively. The fixed connection method of the three is preferably integrated to ensure the stability of the main structure of this embodiment; the reinforcing frame 22 has a plurality of reinforcing ribs built in, and each reinforcing rib forms a plurality of triangular structures inside the reinforcing frame 22, thereby using the firm and reliable characteristics of the triangle to prevent the connecting body 2 itself from deforming when the hydraulic cylinder drives the base plate 1 to contact the ground, thereby ensuring the stability of the overall structure of this embodiment; the connecting plates 21 are symmetrically and evenly distributed with the reinforcing frame 22 as the center, so that each connecting plate 21 plays a role in protecting the side of the reinforcing frame 22, and preventing the reinforcing frame 22 from being subjected to multi-sided force.

[0031] A plurality of wear-resistant components 3 are provided at one end of the base plate 1 away from the connecting ear seat 11, that is, each wear-resistant component 3 replaces the bottom of the base plate 1 to contact the ground, so that the object that originally rubs back and forth on the ground due to the vibration force generated by the operation of the tunnel boring machine is changed from the base plate 1 to the wear-resistant components 3, that is, the wear-resistant components 3 replace the base plate 1 to wear, thereby preventing the structure of the main part of the present embodiment from being damaged, avoiding affecting the normal use of the support, and ensuring the stability of the present embodiment.

[0032] The wear-resistant components 3 are arranged in sequence along the linear direction, so that the wear-resistant components 3 can evenly disperse the pressure from the tunnel boring machine, thereby enhancing the working stability of the tunnel boring machine;

[0033] Each wear-resistant assembly 3 includes a first wear-resistant column 31, a second wear-resistant column 32, a third wear-resistant column 33, and a limit rod 34. The first wear-resistant column 31, the second wear-resistant column 32, and the third wear-resistant column 33 are all fixedly connected to the base plate 1 to ensure the strength of the connection structure between each wear-resistant column and the base plate 1, and prevent each wear-resistant column from being separated from the base plate 1; and the columnar structure of each wear-resistant column can effectively withstand the vertical load (the load from the axial direction of the wear-resistant column), and transfer the weight from the upper structure such as the base plate 1 to the contact surface such as the ground, so as to ensure the stability and safety of the tunnel boring machine supported by this embodiment;

[0034] However, considering that in actual use, the present embodiment rotates with the drum as the center under the action of the hydraulic cylinder to contact the ground, due to the unevenness of the ground, each wear-resistant column may be subjected to unilateral force in the process of contacting the ground, causing each wear-resistant column to be subjected to lateral load (load from the radial direction of the wear-resistant column), which may easily cause deformation phenomena such as structural distortion and affect the normal use of the wear-resistant column.

[0035] Therefore, by passing the limiting rod 34 through the first wear-resistant column 31, the second wear-resistant column 32, and the third wear-resistant column 33, each wear-resistant column is constrained by means of the limiting rod 34, thereby improving the resistance of each wear-resistant column to deformation and ensuring the stability of the overall structure of the wear-resistant assembly 3; the second wear-resistant column 32 is located between the first wear-resistant column 31 and the third wear-resistant column 33, and the two ends of the limiting rod 34 are fixedly connected to the first wear-resistant column 31 and the third wear-resistant column 33, respectively, so that the limiting effect of the limiting rod 34 fully acts on each wear-resistant column, and after the limiting rod 34 is fixedly connected to the first wear-resistant column 31 and the third wear-resistant column 33, it can prevent the limiting rod 34 from detaching from each wear-resistant column due to the rotation of this embodiment, thereby ensuring the integrity and stability of the overall structure of this embodiment.

[0036] like Figure 3-4 , Figure 5 As shown, the base plate 1 in this embodiment is provided with a plurality of connection holes 12 for threaded connection of the first wear-resistant column 31 or the second wear-resistant column 32 or the third wear-resistant column 33, that is, the fixed connection between each wear-resistant column and the base plate 1 is realized in the form of threaded connection, and the two are detachable while ensuring that they can be fixed, so that when the wear-resistant column is worn, the worn wear-resistant column can be replaced, so that this embodiment can maintain a relatively stable working state.

[0037] Each of the first wear-resistant column 31, the second wear-resistant column 32, and the third wear-resistant column 33 has a connecting groove 302 for the limit rod 34 to penetrate, so that the limit rod 34 can be located in the center position of the first wear-resistant column 31, the second wear-resistant column 32, and the third wear-resistant column 33, so that the force from each wear-resistant column in the radial direction (lateral direction) is uniform when acting on the limit rod 34, so that the limit rod 34 can be balanced to bear the force, thereby improving the structural stability and strength of each wear-resistant component 3; both ends of each limit rod 34 are provided with a limit plate 35, and each limit plate 35 is detachably connected to the limit rod 34, and the movement of the limit rod 34 in the horizontal direction is limited by the mutual cooperation between the limit plate 35 and the first wear-resistant column 31 or the third wear-resistant column 33; the detachable connection between each limit plate 35 and the limit rod 34 is preferably completed by threaded connection of the two by bolts or other threaded parts, so as to facilitate the subsequent disassembly of each wear-resistant column.

[0038] The longitudinal cross-section of the limit rod 34 is a rectangular structure, so if each wear-resistant column is to be deformed, it will inevitably apply force to each plane of the limit rod 34, and the rectangular structure can better withstand the pressure from the direction perpendicular to its plane, thereby ensuring the restraining effect of the limit rod 34 on each wear-resistant column, avoiding deformation of each wear-resistant column, and ensuring the stability of this embodiment.

[0039] Each of the first wear-resistant column 31, the second wear-resistant column 32, and the third wear-resistant column 33 has a rotating part 301 for convenient disassembly and assembly. The rotating part 301 is a regular hexagonal structure on the horizontal plane projection surface, so that the staff can easily complete the disassembly and assembly of the wear-resistant column by rotating the rotating part 301 with the help of tools such as wrenches, thereby avoiding the difficulty of disassembly and assembly of the wear-resistant column by the staff due to the surface of the wear-resistant column being too smooth, thereby ensuring the assembly and disassembly efficiency of the wear-resistant column; at the same time, the diameter size of the rotating part 301 should be larger than the aperture size of the connecting hole 12, so that the rotating part 301 also plays a limiting role to a certain extent, preventing the wear-resistant column from being displaced in the axial direction on the base plate 1.

[0040] A plurality of buffer bodies 13 are provided at one end of the bottom plate 1 close to the connecting ear seat 11, and each buffer body 13 corresponds to each connecting hole 12 one by one. The buffer body 13 includes a buffer cavity 131 and a buffer member 132. The buffer cavity 131 is connected to the connecting hole 12, and the buffer member 132 is fixedly arranged inside the buffer cavity 131 and abuts against the first wear-resistant column 31, the second wear-resistant column 32, or the third wear-resistant column 33. Each buffer member 132 is preferably an elastic member such as a spring. After the first wear-resistant column 31, the second wear-resistant column 32, or the third wear-resistant column is assembled, it will abut against the buffer member 132. When each wear-resistant column is subjected to force, it will transfer the force to the buffer member 132, so that the buffer member 132 is deformed to absorb the force and energy (external pressure, external impact) applied from the outside. This deformation alleviates the effect of impact and pressure by converting force into elastic potential energy, so that this embodiment can support the tunneling machine more stably.

[0041] Example 2

[0042] like Figure 6 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that: the ends of the first wear-resistant column 31, the second wear-resistant column 32, and the third wear-resistant column 33 away from the bottom plate 1 are all inverted conical structures, that is, the diameter of the end of each wear-resistant column away from the bottom plate 1 is smaller than the diameter of the end of each wear-resistant column close to the bottom plate 1. In this way, when the ground is relatively soft, according to the principle that the applied pressure remains unchanged, the area of ​​the applied point becomes smaller, and the applied force becomes larger, each wear-resistant column can give the ground a greater pressure, can be embedded in the ground, and increase its contact area with the ground. A larger contact area means that the friction between the object and the supporting surface increases, making it more difficult to be moved or tilted, so that this embodiment plays a more stable supporting role.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
