Description

Technical Field

[0001] The utility model relates to the technical field of disassembling a guide sleeve of a propulsion oil cylinder of a shield machine, in particular to a disassembling tool for disassembling a guide sleeve of a propulsion oil cylinder of a shield machine. Background Art

[0002] A shield machine is a tunnel boring machine that uses the shield method. The shield construction method is that the tunnel boring machine constructs (lays) the "shield" (referring to the supporting segments) of the tunnel while excavating. It is different from the open construction method. The shield machine's propulsion cylinder is its main power structure, so the shield machine's propulsion cylinder is also a damaged component. When the shield machine's propulsion cylinder is disassembled and repaired, the guide sleeve on it needs to be disassembled. At this time, the shield machine's propulsion cylinder guide sleeve disassembly tooling is required.

[0003] At present, the disassembly tools for the guide sleeve of the thrust cylinder of the shield machine are divided into manual tools and electric tools. For the manual tools, when disassembling the guide sleeve, one end of the rod is usually pressed against the guide sleeve, and then the personnel use a hammer to hit the other end of the rod to achieve the knocking of the guide sleeve, and then the guide sleeve is knocked around in turn to loosen it, and then the guide sleeve can be removed. This method has the following problems: it is impossible to achieve uniform and synchronous force knocking on the guide sleeve around the circle, and a single point knocking can easily cause the guide sleeve to deflect and get stuck, and it can easily cause the guide sleeve to be damaged. In view of this, we propose a disassembly tool for the guide sleeve of the thrust cylinder of the shield machine. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet actual needs, and provide a shield machine propulsion cylinder guide sleeve disassembly tool to solve the technical problem that the current shield machine propulsion cylinder guide sleeve disassembly tool cannot perform uniform and synchronous force knocking on the guide sleeve around a circle.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is as follows: a shield machine propulsion cylinder guide sleeve disassembly tool is designed, including a support structure for pressing on a circle of the shield machine propulsion cylinder guide sleeve, a conductive structure is arranged on the top of the support structure, the conductive structure includes a conductive rod and a knocking seat, the conductive rods are equidistantly arranged around the knocking seat, the conductive rods are movably connected to the collar, and the knocking seat is in a truncated cone shape;

[0006] The supporting structure comprises a collar and a limiting sleeve, the limiting sleeve is slidably arranged outside the collar, and a sleeve gap is reserved between the inner wall of the limiting sleeve and the outer wall of the collar.

[0007] Preferably, a circular first through hole is formed at the top of the limiting sleeve, and the diameter of the first through hole is the same as the outer diameter of the collar.

[0008] Preferably, a plurality of groups of protrusions are arranged equidistantly around the inside of the first through hole, and sliding grooves corresponding to the protrusions are arranged on the surface of the collar, and the protrusions are located in the corresponding sliding grooves.

[0009] Preferably, a fixing screw hole is arranged at the bottom end of the conduction rod, a plurality of groups of rectangular mounting seats are arranged equidistantly around the top of the ring, and a second through hole is opened on the top of the mounting seat, the bottom end of the conduction rod is inserted into the second through hole, and a fixing bolt is screwed on the surface of the mounting seat.

[0010] Preferably, a limiting protrusion is arranged at the top end of the conduction rod, a plurality of groups of rectangular third through holes are arranged equidistantly around the striking seat, and the conduction rod passes through the corresponding third through holes.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model is composed of a support structure and a conduction structure. When it is necessary to disassemble the guide sleeve of the shield machine propulsion cylinder, the support structure is put on the shield machine propulsion cylinder and pressed against the guide sleeve of the shield machine propulsion cylinder for one circle. Then, a person strikes the conduction structure with a hammer, and the conduction structure transfers the force evenly to the support structure. Then, the support structure transfers the force evenly to the guide sleeve of the shield machine propulsion cylinder for one circle. Thus, the guide sleeve of the shield machine propulsion cylinder can be struck evenly all around synchronously, thereby avoiding the situation in which the guide sleeve of the shield machine propulsion cylinder is deflected and stuck due to uneven force on the guide sleeve.

[0013] 2. The utility model is composed of a collar and a limit sleeve. The bottom of the collar can be pressed against the guide sleeve of the shield machine's propulsion cylinder for one circle, and then the limit sleeve on the collar can be slid to fit around the outside of the shield machine's propulsion cylinder body for one circle, thereby limiting the entire support structure so that the collar on it can be stably and accurately pressed against the guide sleeve of the shield machine's propulsion cylinder, ensuring the stability of the knocking and disassembly of the guide sleeve of the shield machine's propulsion cylinder.

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0023] Embodiment: A shield machine propulsion cylinder guide sleeve disassembly tool, see Figures 1 to 7 , including a support structure 1 for pressing against a guide sleeve of a shield machine propulsion cylinder, a conductive structure 2 is arranged on the top of the support structure 1. When the guide sleeve of the shield machine propulsion cylinder is disassembled, the support structure 1 is mounted on the shield machine propulsion cylinder, and then pressed against the guide sleeve of the shield machine propulsion cylinder for a circle, and then a person strikes the conductive structure 2 with a hammer, and the conductive structure 2 evenly transfers the force to the support structure 1, and then the support structure 1 evenly transfers the force to the guide sleeve of the shield machine propulsion cylinder for a circle, thereby achieving synchronous and uniform force striking of the guide sleeve of the shield machine propulsion cylinder for a circle, avoiding the occurrence of deflection and jamming of the guide sleeve of the shield machine propulsion cylinder due to uneven force striking;

[0024] Specifically, the conductive structure 2 includes a conductive rod 201 and a striking seat 202. The conductive rods 201 are equidistantly arranged around the striking seat 202. The conductive rods 201 are movably connected to the ring 101. The striking seat 202 serves as a force-bearing structure for hammer striking. The force generated by the hammer striking the striking seat 202 is evenly transmitted to the supporting structure 1 through the conductive rod 201.

[0025] Furthermore, a fixing screw hole 204 is arranged at the bottom end of the conduction rod 201, and a plurality of groups of rectangular mounting seats 106 are equidistantly arranged around the top of the ring 101, and a second through hole 107 is opened at the top of the mounting seat 106. The bottom end of the conduction rod 201 is inserted into the second through hole 107, and a fixing bolt 108 is screwed on the surface of the mounting seat 106. When the conduction rod 201 is installed, the conduction rod 201 is inserted into the second through hole 107 of the mounting seat 106, and then the fixing bolt 108 is screwed into the fixing screw hole 204 of the conduction rod 201, so as to fix the conduction rod 201. In this way, the conduction rod 201 and the support structure 1 can be disassembled and assembled, which is convenient for disassembly and carrying of the device.

[0026] Furthermore, a limiting protrusion 203 is arranged at the top of the conduction rod 201, and a plurality of groups of rectangular third through holes 205 are equidistantly arranged around the striking seat 202, and the conduction rod 201 passes through the corresponding third through holes 205, and the third through holes 205 of the striking seat 202 are inserted and installed from the top of the corresponding conduction rod 201. When the striking seat 202 drops to a certain extent, the limiting protrusion 203 supports the striking seat 202, and then the personnel can strike the striking seat 202 with a hammer. The striking seat 202 and the conduction rod 201 can also be detachably installed, which is convenient for disassembly and carrying of the device.

[0027] It is worth noting that the striking seat 202 is in the shape of a truncated cone. When a hammer strikes the top of the truncated cone-shaped striking seat 202 , the force can be evenly distributed to a plurality of groups of conducting rods 201 .

[0028] In a specific embodiment, the support structure 1 includes a ring 101 and a limiting sleeve 102. The limiting sleeve 102 is slidably arranged on the outside of the ring 101, and a fitting gap is reserved between the inner wall of the limiting sleeve 102 and the outer wall of the ring 101. In the process of the support structure 1 pressing the guide sleeve of the shield machine propulsion cylinder, the ring 101 is firstly put on the shield machine propulsion cylinder, and its bottom is pressed against the guide sleeve of the shield machine propulsion cylinder for one circle, and then the limiting sleeve 102 is lowered, so that the fitting gap between the limiting sleeve 102 and the ring 101 is pressed against the outside of the shield machine propulsion cylinder body for one circle, so that the entire support structure 1 can be limited, so that the ring 101 on it can be stably and accurately pressed against the guide sleeve of the shield machine propulsion cylinder, thereby ensuring the stability of the knocking and disassembly of the guide sleeve of the shield machine propulsion cylinder.

[0029] Specifically, a circular first through hole 103 is formed at the top of the limiting sleeve 102 , and the diameter of the first through hole 103 is the same as the outer diameter of the collar 101 . The limiting sleeve 102 can be sleeved on the collar 101 through the first through hole 103 .

[0030] Furthermore, a plurality of groups of protrusions 104 are evenly spaced around the inside of the first through hole 103, and a slide groove 105 corresponding to the protrusion 104 is arranged on the surface of the ring 101, and the protrusion 104 is located in the corresponding slide groove 105. With the cooperation of the slide groove 105 and the protrusion 104, it can be ensured that the ring 101 and the limit sleeve 102 can slide relative to each other. The utility model solves the technical problem that the current shield machine propulsion cylinder guide sleeve disassembly tooling cannot perform uniform and synchronous force knocking on the guide sleeve around the circle through the support structure 1 and the conduction structure 2.

[0031] Working principle: When disassembling the guide sleeve of the shield machine's propulsion cylinder, first, put the support structure 1 on the shield machine's propulsion cylinder, and then make it press against the guide sleeve of the shield machine's propulsion cylinder for a circle. Then, the personnel knock the conduction structure 2 with a hammer, and the conduction structure 2 transfers the force evenly to the support structure 1. Then, the support structure 1 transfers the force evenly to the guide sleeve of the shield machine's propulsion cylinder for a circle. In this way, the guide sleeve of the shield machine's propulsion cylinder can be evenly struck synchronously for a circle, avoiding the situation where the shield machine's propulsion cylinder guide sleeve is deflected and stuck due to uneven force on the guide sleeve.

[0032] Secondly, when the hammer strikes the conductive structure 2, the hammer strikes the top of the truncated cone-shaped striking seat 202, and then the force can be evenly dispersed to a plurality of groups of conductive rods 201, and then the conductive rods 201 evenly transfer the force to the supporting structure 1, and then the supporting structure 1 evenly transfers the force to the guide sleeve of the shield machine propulsion cylinder for one circle;

[0033] Finally, in the process of supporting structure 1 to close the guide sleeve of shield machine propulsion cylinder, first, put the ring 101 on the shield machine propulsion cylinder, and make its bottom close to the guide sleeve of shield machine propulsion cylinder for one circle, then slide the limiting sleeve 102 down, so that the fitting gap between the limiting sleeve 102 and the ring 101 is close to the outside of the cylinder body of shield machine propulsion cylinder for one circle, so that the entire supporting structure 1 can be limited, so that the ring 101 on it can be stably and accurately close to the guide sleeve of shield machine propulsion cylinder, ensuring the stability of knocking and disassembling the guide sleeve of shield machine propulsion cylinder.

[0034] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
