Description

Technical Field

[0001] This invention relates to the field of tooling technology for manufacturing large components such as ships and steel structures, and in particular to an assembled jig base and its usage method. Background Technology

[0002] As a crucial support tool in the manufacturing process of large components such as ships and steel structures, the stability, ease of assembly and disassembly, and reliability of the jig base directly affect construction efficiency and safety. Currently, a typical jig base consists of a base body and mounting seats fixed to it, with the jig's support pipes fixed to the mounting seats via plug-in or bolt connections.

[0003] However, the existing jig base technology has the following significant drawbacks in practical applications: 1. Rigid impact easily damages: When the hoisting jig is in place, the mounting feet of the jig and the mounting base of the base are often in rigid contact. Due to operational errors or gravitational acceleration, the mounting feet are very prone to violent impact with the mounting base, causing deformation and damage to both, which not only affects the connection strength and service life, but also poses a safety hazard; 2. Bolt holes are prone to clogging: Bolt sleeves used for connection are usually directly exposed to the external environment. In the complex environment of the construction site, impurities such as sand and welding slag can easily enter the threaded holes of the bolt sleeves, causing thread blockage or damage. This makes it impossible to screw the bolts in smoothly, causing great inconvenience to the disassembly and assembly operations, and may even require extra time for cleaning or repair. 3. Difficult alignment and low efficiency: During the installation process, the support pipe of the jig and the insertion pipe of the base, as well as the bolt holes of the mounting feet and the bolt sleeves of the base, need to be precisely aligned. The existing base lacks an effective auxiliary positioning and buffering guide mechanism. The alignment process often relies on repeated manual adjustments, which is time-consuming and labor-intensive, increasing the labor intensity and working time of workers. 4. Insufficient initial stability: Most bases lack an immediate and effective anchoring mechanism to the ground after being in place. When bearing the weight of the jig and components, especially on soft ground or with a slight slope, the base may be at risk of sliding or displacement, affecting the overall initial stability of the jig.

[0004] Therefore, there is an urgent need for a jig base that can effectively mitigate installation impact, protect connection threads, assist in alignment of the kit and improve ground anchoring stability, in order to solve the above-mentioned technical problems. Summary of the Invention

[0005] This application provides an assembled jig base and its usage method. The first problem to be solved is that the rigid impact between the jig mounting feet and the base mounting seat is easily damaged. The second problem to be solved is that the threaded holes of the bolt sleeve are easily blocked. The third problem to be solved is that the jig support pipe and base insertion pipe, and the mounting feet and threaded sleeve are difficult to align. The fourth problem to be solved is that the initial stability of the base is poor after it is in place.

[0006] To solve the above-mentioned technical problems, this application provides an assembled jig base, including: a base body, on which at least one mounting seat is fixedly disposed; and further including: a buffer protection module disposed on the mounting seat, used to buffer the impact of its mounting feet and protect the connecting threaded holes during jig installation. The elastic alignment and anchoring module is movably mounted on the mounting base and penetrates the base body. It is used to provide support to assist alignment during the initial installation of the jig and to be forced downward to achieve anchoring with the ground when the jig is in place. The elastic alignment and anchoring module and the buffer protection module are spatially independent of each other, so that the mounting feet of the jig can first contact the elastic alignment and anchoring module to complete the alignment, and then contact the buffer protection module to compress.

[0007] Preferably, the buffer protection module includes: a bolt sleeve, the lower end of which is fixed to the inner wall of the mounting base, and the upper end is open for receiving the fixing bolt; The protective sleeve is axially slidably fitted onto the outside of the bolt sleeve, with its upper section protruding upward from the top surface of the mounting base to form a dust cap structure; A support spring is sleeved on the lower part of the bolt sleeve and acts between the protective sleeve and the internal fixing structure of the mounting base, providing an upward elastic support force for the protective sleeve.

[0008] Preferably, the bottom of the bolt sleeve is fixedly connected to the inner wall of the mounting base by a fixing block, and the upper end face of the bolt sleeve is flush with the top surface of the mounting base.

[0009] Preferably, the protective sleeve has a rounded rectangular cross-section and its length is shorter than that of the bolt sleeve; the inner diameter of the protective sleeve is larger than the outer diameter of the bolt sleeve.

[0010] Preferably, the elastic alignment and anchoring module includes: a tube, which is movably inserted into the mounting base for guiding and mounting the support tube of the mounting frame; A limiting piece is fixedly installed on the upper part of the insertion tube to support the mounting feet of the receiving and mounting frame; A push plate is fixedly connected to the bottom of the insertion tube and located below the base body; An elastic component is disposed between the push plate and the base body to provide an upward elastic restoring force for the insertion tube; At least one plug rod is fixed at its upper part to the bottom surface of the push plate and extends downward through the corresponding through hole on the base body.

[0011] Preferably, the elastic component is a connecting spring, and the upper two ends of the connecting spring are respectively connected to the push plate and the base body through a sleeve block, and the axis of the sleeve block coincides with the axis of the insertion tube.

[0012] Preferably, the lower surface of the limiting piece is roughened, and the top surface of the mounting base has a corresponding circular groove adapted to the limiting piece, the diameter of the circular groove being larger than the diameter of the limiting piece.

[0013] Preferably, the top surface of the limiting plate is lower than the top surface of the insertion tube to facilitate the introduction of the tire frame branch tube. The lower end of the insertion rod is provided with a tapered tip or rounded corner to facilitate insertion into the ground. The insertion tube, the push plate, and the insertion rod are in a first position under the support of the elastic component. At this time, the limiting plate is in contact with or adjacent to the top surface of the mounting base, and the lower end of the insertion rod is retracted. When subjected to downward pressure, it can move to a second position, at which time the lower end of the insertion rod extends to insert into the ground.

[0014] Preferably, the protective sleeve and the fixing block are not in contact with the push plate in the vertical direction, and the push plate is not in contact with the mounting base. Supporting ribs are fixedly provided on both sides of the mounting base, and the other end of the supporting ribs is fixedly connected to the base body.

[0015] The specific steps of using an assembled jig base are as follows: S1: Initial positioning: Place the jig base on the installation site, align the support pipe of the jig to be installed and fit it onto the insertion pipe, so that the mounting feet of the jig are supported on the limiting piece. S2: Assisted alignment: With the support of the elastic component, the jig is in a rotatable state. Rotate the jig so that the bolt holes on its mounting feet are aligned with the buffer protection module on the mounting base. S3: Downward Anchoring: Continue to lower the jig frame. The weight of the jig frame overcomes the elastic force of the elastic component, driving the push plate to move the plug rod downward, so that the lower end of the plug rod is inserted into the ground, achieving instant anchoring. S4: Buffer contact: During the pressing process, the mounting feet of the frame contact and press down on the protective sleeve, compressing the support spring, which provides buffer until the mounting feet are firmly seated on the top surface of the mounting base; S5: Fastening connection: Pass the fastening bolts through the bolt holes on the mounting feet of the frame and the protective sleeve in sequence, and screw them into the bolt sleeve to complete the installation.

[0016] Compared with the prior art, the present invention has the following features and beneficial effects: This invention effectively buffers and prevents impact damage. When the jig is lowered, its mounting feet first contact and compress the protective sleeve. The support spring is partially compressed, absorbing impact energy and preventing rigid impact between the mounting film and the mounting base, thus protecting both structures. Under normal conditions, the extended protective sleeve acts like a "dust cap," covering the threaded holes of the bolt sleeve, effectively preventing sand and impurities from entering and ensuring smooth bolt insertion. This improves connection reliability and ease of assembly and disassembly. Before the jig is fully in place, its mounting support pipe is first inserted into the insertion tube, and the mounting feet rest on the limiting plate. At this time, supported by the connecting spring, the jig is in a "suspended" state, allowing it to rotate easily. Workers can fine-tune the jig angle in this state to easily align the bolt holes on the mounting feet with the bolt sleeve below. This greatly reduces the difficulty of docking. After alignment, the jig continues to be lowered. Its gravity overcomes the elasticity of the connecting spring, pushing the insertion tube, push plate, and insertion rod downwards. The sharp insertion rod inserts into the ground soil under pressure, achieving immediate anchoring of the base. This significantly improves the initial stability of the jig system before bearing load, preventing slippage. The buffering, alignment, and anchoring functions are achieved through the linkage of components such as the insertion tube, spring, and protective sleeve. This solves the problems of easy damage from rigid impact between the jig's mounting feet and the base's mounting seat, easy blockage of the threaded holes of the bolt sleeve, difficulty in aligning the jig's branch pipe and the base's insertion tube, the mounting feet and the threaded sleeve, and poor initial stability of the base after positioning. The invention has a compact structure, requires no additional power or complex operation, and is driven entirely by the jig's own weight, making it highly practical. Attached Figure Description

Detailed Implementation

[0019] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0020] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0021] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] like Figure 1-8 As shown, in the first embodiment of this application, an assembled jig base includes: a base body 1, on which at least one mounting seat 12 is fixedly disposed; characterized in that it further includes: a buffer protection module disposed on the mounting seat 12, used to buffer the impact of its mounting feet and protect the connecting threaded holes when the jig is installed. The elastic alignment and anchoring module is movably mounted on the mounting base 12 and penetrates the base body 1. It is used to provide support to assist alignment during the initial installation of the jig and to be forced downward when the jig is in place to achieve anchoring with the ground. The elastic alignment and anchoring module and the buffer protection module are spatially independent, so that the mounting feet of the jig can first contact the elastic alignment and anchoring module to complete the alignment, and then contact the buffer protection module to compress.

[0024] Furthermore, the buffer protection module includes: a bolt sleeve 43, the lower end of which is fixed to the inner wall of the mounting base 12, and the upper end is open for receiving the fixing bolt; The protective sleeve 4 is axially slidably fitted onto the outside of the bolt sleeve 43, with its upper section protruding upward from the top surface of the mounting base 12 to form a dust cap structure. The support spring 41 is sleeved on the lower part of the bolt sleeve 43 and acts between the protective sleeve 4 and the internal fixing structure of the mounting base 12, providing an upward elastic support force for the protective sleeve 4.

[0025] Furthermore, the bottom of the bolt sleeve 43 is fixedly connected to the inner wall of the mounting base 12 via the fixing block 42, and the upper end face of the bolt sleeve 43 is flush with the top surface of the mounting base 12.

[0026] Furthermore, the protective sleeve 4 has a rounded rectangular cross-section, and its length is shorter than that of the bolt sleeve 43.

[0027] Furthermore, the flexible alignment and anchoring module includes: a tube 2, which is movably inserted into the mounting base 12 for guiding and mounting the branch tube of the mounting frame; The limiting piece 22 is fixedly installed on the upper part of the insertion tube 2 to support the mounting feet of the receiving mounting frame; The push plate 23 is fixedly connected to the bottom of the insertion tube 2 and located below the base body 1; An elastic component is disposed between the push plate 23 and the base body 1 to provide an upward elastic restoring force for the insertion tube 2; At least one plug rod 3 is fixed to the bottom surface of the push plate 23 at its upper part and extends downward through the corresponding through hole on the base body 1.

[0028] Furthermore, the elastic component is a connecting spring 21. The upper two ends of the connecting spring 21 are connected to the push plate 23 and the base body 1 respectively through the sleeve block 24. The axis of the sleeve block 24 coincides with the axis of the insertion tube 2.

[0029] Furthermore, the lower surface of the limiting piece 22 is rough, and the top surface of the mounting base 12 has a corresponding circular groove that matches the limiting piece 22. The diameter of the circular groove is larger than the diameter of the limiting piece 22.

[0030] Furthermore, like Figure 1-8 As shown in the second embodiment of this application, the mounting hole of the bolt sleeve 43 serves a protective function, which can prevent dust carried by the outside air from entering the interior of the bolt sleeve 43 during the handling of the jig, and enable the bolts on the jig mounting feet to be properly installed with the bolt sleeve 43.

[0031] The protective sleeve 4 has a rounded rectangular cross-section. The length of the protective sleeve 4 is shorter than the length of the bolt sleeve 43. The bolt sleeves 43 are evenly distributed on the mounting base 12. When used under normal conditions, the upper end of the protective sleeve 4 extends from the mounting base 12 and can protect the mounting hole of the bolt sleeve 43. This can prevent dust carried by the outside air from entering the interior of the bolt sleeve 43 when the jig is being transported, and ensure that the bolts on the jig mounting feet can be properly installed with the bolt sleeve 43.

[0032] In the third embodiment of this application, the insertion tube 2 is inserted into the mounting branch tube of the frame, and the mounting feet of the frame abut against the limiting plate 22. When the mounting feet abut against the limiting plate 22, the restoring force of the connecting spring 21 can drive the limiting plate 22 on the insertion tube 2 to support the mounting feet of the frame through the pushing plate 23. Before the mounting feet come into contact with the protective sleeve 4, the operator can rotate the mounting feet on the frame on the limiting plate 22, thereby facilitating the alignment of the bolts on the mounting feet with the bolt sleeve 43, so that the bolts on the mounting feet can be easily installed with the bolt sleeve 43.

[0033] A limiting piece 22 is fixed to the upper part of the insertion tube 2. The limiting piece 22 abuts against the top surface of the mounting base 12, and the pushing plate 23 abuts against the top surface of the base body 1.

[0034] Multiple insertion rods 3 are distributed on the bottom surface of the push plate 23. The elastic components on the push plate 23 include a connecting spring 21. Both the upper and lower ends of the connecting spring 21 are fitted with connecting blocks. The connecting block 24 at the upper end of the connecting spring 21 is fixed to the push plate 23, and the connecting block 24 at the lower end of the connecting spring 21 is fixed to the base body 1. When used under normal conditions, the restoring force of the connecting spring 21 can drive the insertion tube 2 to move upward through the push plate 23. The advantage of this design is that it can prevent the mounting feet of the frame from directly colliding with the protective sleeve 4 when they are connected to the mounting base 12, and prevent the protective sleeve 4 from damaging the bolt sleeve 43. It ensures that after the mounting feet are connected to the mounting base 12, the bolts on the mounting feet can be firmly connected to the bolt sleeve 43. When the mounting feet of the jig need to be connected with the mounting base 12, the insert tube 2 will be inserted into the mounting branch tube of the jig. At the same time, the mounting feet of the jig will abut against the limiting plate 22. When the mounting feet abut against the limiting plate 22, the restoring force of the connecting spring 21 can drive the limiting plate 22 on the insert tube 2 to support the mounting feet of the jig through the push plate 23. Before the mounting feet come into contact with the protective sleeve 4, the operator can rotate the mounting feet on the jig on the limiting plate 22, so as to make it easier for the bolts on the mounting feet to align with the bolt sleeve 43.

[0035] The bottom surface of the limiting piece 22 is rough, and a circular groove is provided on the mounting base 12. The depth of the circular groove is the same as the thickness of the limiting piece 22, and the diameter of the circular groove is larger than the diameter of the limiting piece 22. This can prevent the limiting piece 22 from being adsorbed into the circular groove on the mounting base 12, so that the limiting piece 22 can be separated from the mounting base 12.

[0036] In the fourth embodiment of this application, when the mounting feet of the jig abut against the limiting plate 22, the jig can compress the connecting spring 21 under the action of gravity. At this time, the pushing plate 23 can drive the plug rod 3 to be inserted into the soil of the construction site, so that the base body 1 can be stably placed on the construction site, thereby ensuring that the jig is stably placed on the construction site through the base.

[0037] The axis of the socket block 24 coincides with the axis of the insertion tube 2. The connecting spring 21 is distributed in the middle of the bottom surface of the push plate 23. The lower end of the insertion rod 3 is rounded. When the insertion rod 3 is used in the normal state, the lowest end of the insertion rod 3 is higher than the bottom surface of the base body 1. This can prevent the lowest end of the insertion rod 3 from being damaged during the transportation of the frame.

[0038] The top surface of the limiting plate 22 is lower than the top surface of the insertion tube 2. Both sides of the mounting base 12 are fixed with support ribs 11, and the end of the support rib facing away from the mounting base 12 is fixed to the base body 1.

[0039] The protective sleeve 4 and the fixing block 42 do not contact the push plate 23. The inner diameter of the protective sleeve 4 is larger than the inner diameter of the bolt sleeve 43. The push plate 23 does not contact the mounting base 12.

[0040] The cannula 2 is inserted into the inside of the outer tire frame, the limiting piece 22 abuts against the outer tire frame, and the protective sleeve 4 abuts against the outer tire frame; When the mounting feet of the jig abut against the limiting plate 22, the jig can press the connecting spring 21 under the action of gravity. At this time, the push plate 23 can drive the plug rod 3 to be inserted into the soil of the construction site, so that the base body 1 is placed stably on the construction site, thereby ensuring that the jig is placed stably on the construction site through the base. When workers need to move the placement of the base of the jig, they can use an external hoisting device to lift the jig. This is the existing method of handling the jig base. In order to facilitate workers to master the handling method of the jig base, this solution does not design the transportation part of the jig base. When the external hoisting device lifts the jig base, the restoring force of the connecting spring 21 can drive the insertion tube 2 to move upward through the push plate 23. This can enable the push plate 23 to drive the insertion rod 3 to be pulled out from the soil, so that the insertion rod 33 can be used again later.

[0041] The steps for use are as follows: S1: Initial positioning: Place the base of the jig on the installation site, align the branch pipe of the jig to be installed and fit it onto the insertion pipe 2, so that the mounting feet of the jig are supported on the limiting plate 22. S2: Assisted alignment: With the support of the elastic component, the jig is in a rotatable state. Rotate the jig so that the bolt holes on its mounting feet are aligned with the buffer protection module on the mounting base 12. S3: Downward Anchoring: Continue to lower the jig frame. The weight of the jig frame overcomes the elastic force of the elastic component, driving the push plate 23 to move the plug rod 3 downward, so that the lower end of the plug rod 3 is inserted into the ground, achieving instant anchoring. S4: Buffer contact: During the pressing process, the mounting feet of the jig contact and press down on the protective sleeve 4, compressing the support spring 41. The support spring 41 provides buffer until the mounting feet are firmly seated on the top surface of the mounting base 12. S5: Fastening connection: Pass the fastening bolts through the bolt holes on the mounting feet of the jig and the protective sleeve 4 in sequence, and screw them into the bolt sleeve 43 to complete the installation.

[0042] The existing jig mainly consists of mounting support pipes and crossbeams. In order to facilitate the jig to be fixed to the existing jig base by bolts, the lower end of the mounting support pipe of the jig will also be fixed with mounting feet. In actual use, external bolts will pass through the mounting feet and the jig base for fixation. The base of this jig is designed for the aforementioned jig. In actual use, the staff will attach the jig's mounting support pipe to the insertion pipe 2. The jig can use its own weight to drive the mounting feet to press against the protective sleeve 4, which in turn causes the protective sleeve 4 to press against the support spring 41 on the bolt sleeve 43. When the jig's mounting feet press against the protective sleeve 4, the support spring 41 can support the protective sleeve 4 under the action of restoring force, thereby preventing the mounting feet of the jig from colliding with the mounting base 12 when the jig and the mounting base 12 are connected, thus preventing damage to the mounting feet of the jig. When used under normal conditions, the upper end of the protective sleeve 4 extends from the mounting base 12 and can protect the mounting hole of the bolt sleeve 43. This can prevent dust carried by the outside air from entering the interior of the bolt sleeve 43 when the jig is being transported, and ensure that the bolts on the jig mounting feet can be properly installed with the bolt sleeve 43. When used under normal conditions, the restoring force of the connecting spring 21 can drive the insertion tube 2 to move upward through the push plate 23. The advantage of this design is that it can prevent the mounting feet of the frame from directly colliding with the protective sleeve 4 when they are connected to the mounting base 12, thus preventing the protective sleeve 4 from damaging the bolt sleeve 43 and ensuring that the bolts on the mounting feet can be securely connected to the bolt sleeve 43 after they are connected to the mounting base 12. When the mounting feet of the jig need to be connected with the mounting base 12, the insert tube 2 will be inserted into the mounting branch tube of the jig, and at the same time the mounting feet of the jig will abut against the limiting plate 22. When the mounting feet abut against the limiting plate 22, the restoring force of the connecting spring 21 can drive the limiting plate 22 on the insert tube 2 to support the mounting feet of the jig through the push plate 23. Before the mounting feet come into contact with the protective sleeve 4, the operator can rotate the mounting feet on the jig on the limiting plate 22, so as to make it easier for the bolts on the mounting feet to align with the bolt sleeve 43. When the mounting feet of the jig abut against the limiting plate 22, the jig can compress the connecting spring 21 under the action of gravity. At this time, the push plate 23 can drive the plug rod 3 to be inserted into the soil of the construction site, so that the base body 1 can be stably placed on the construction site, thereby ensuring that the jig is stably placed on the construction site through the base. When workers need to move the placement of the base of the jig, they can use an external hoisting device to lift the jig. This is the existing method of handling the jig base. In order to facilitate workers to master the handling method of the jig base, this solution does not design the transportation part of the jig base. When the external hoisting device lifts the jig base, the restoring force of the connecting spring 21 can drive the insertion tube 2 to move upward through the push plate 23. This can enable the push plate 23 to drive the insertion rod 3 to be pulled out from the soil, so that the insertion rod 3 can be used again later.

The lower end of the insertion rod (3) is provided with a conical tip or rounded corner to facilitate insertion into the ground. The insertion tube (2), the push plate (23) and the insertion rod (3) are in a first position under the support of the elastic component. At this time, the limiting piece (22) is in contact with or adjacent to the top surface of the mounting base (12), and the lower end of the insertion rod (3) is retracted. When subjected to downward pressure, it can move to a second position, at which time the lower end of the insertion rod (3) extends out to insert into the ground.

9. A prefabricated jig base according to claim 5, characterized in that, The protective sleeve (4) and the fixing block (42) are not in contact with the push plate (23) in the vertical direction, and the push plate (23) is not in contact with the mounting base (12). Supporting ribs (11) are fixedly provided on both sides of the mounting base (12), and the other end of the supporting ribs (11) is fixedly connected to the base body (1).

10. A method of using an assembled jig base as described in any one of claims 1-9, characterized in that, The specific steps of the method of use are as follows: S1: Initial positioning: Place the base of the frame on the installation site, align the branch pipe of the frame to be installed and fit it on the insertion pipe (2), so that the mounting feet of the frame are supported on the limiting piece (22). S2: Assisted alignment: Under the support of the elastic component, the frame is in a rotatable state. Rotate the frame so that the bolt holes on its mounting feet are aligned with the buffer protection module on the mounting base (12); S3: Downward Anchoring: Continue to lower the frame, the weight of the frame overcomes the elastic force of the elastic component, driving the push plate (23) to move the plug rod (3) downward, so that the lower end of the plug rod (3) is inserted into the ground to achieve instant anchoring; S4: Buffer contact: During the pressing process, the mounting feet of the frame contact and press down on the protective sleeve (4), compressing the support spring (41), which provides buffer until the mounting feet sit firmly on the top surface of the mounting base (12); S5: Fastening connection: Pass the fastening bolts through the bolt holes on the mounting feet of the frame and the protective sleeve (4) in sequence, and screw them into the bolt sleeve (43) to complete the installation.
