Description

Technical Field

[0001] The invention relates to the technical field of tunnel construction equipment, and in particular to a shield tunnel segment hoisting device. Background Art

[0002] The lifting of shield tunnel segments is an important part of shield construction, which involves the lifting, transportation and installation of segments.

[0003] The existing pipe segment lifting process mostly uses equipment such as suction cup machines, pipe segment lifting devices or soft contact props. For suction cup machines and pipe segment lifting devices, since both equipment need to contact the pipe segment, collisions are easy to occur during the lifting process, resulting in problems such as damage to the pipe segment or damage to the appearance. Soft contact props use the bolt structure on the pipe segment and use a grabbing method to lift the pipe segment, which can reduce the problem of pipe segment damage to a certain extent.

[0004] However, most existing grasping structures adopt a columnar structure. Since the size of the positioning hole needs to be adapted to the bolt, the size is small. When connecting, it is necessary to manually align the grasping structure with the bolt and put the bolt into the positioning hole of the grasping structure, which greatly affects the working efficiency.

[0016] As an optional implementation, a first lifting ear portion is formed at one end of the first connecting arm away from the beam body, and a second lifting ear portion is formed at one end of the second connecting arm away from the beam body.

[0017] Compared with the prior art, the shield tunnel segment hoisting equipment provided by the present invention has the following advantages: The shield tunnel segment lifting equipment provided by the present invention includes a positioning mechanism and a clamping mechanism; the positioning mechanism includes a crossbeam, and the crossbeam is formed with a guide portion extending along the length direction of the crossbeam; the clamping mechanism includes a positioning rod, a first elastic member, a second elastic member, a first clamping assembly and a second clamping assembly, the positioning rod is connected to the crossbeam along the length direction of the crossbeam, and the positioning rod is located in the guide portion; the first clamping assembly and the second clamping assembly are both slidably arranged on the positioning rod, the first clamping assembly is formed with a first notch, and the second clamping assembly is formed with a second notch, the first elastic member and the second elastic member are both sleeved on the positioning rod, and the first elastic member is located between the first clamping assembly and one end of the guide portion, and the second elastic member is located between the second clamping assembly and the other end of the guide portion, so that the first notch and the second notch are connected to form a positioning space.

[0018] From this analysis, it can be known that the crossbeam can provide a mounting base for the positioning rod, and the guide portion formed along the length direction of the crossbeam can accommodate and limit the moving trajectory of the first clamping assembly and the second clamping assembly. It can be understood that, since the first elastic member and the second elastic member in the present application are both sleeved on the positioning rod, and the first elastic member is located between the first clamping assembly and one end of the guide portion, and the second elastic member is located between the second clamping assembly and one end of the guide portion, therefore, one end of the first elastic member and one end of the second elastic member can abut against the guide portion, and the other end abuts against the corresponding first clamping assembly and second clamping assembly, so that the first elastic member and the second elastic member can always keep the first clamping assembly and the second clamping assembly in a state of abutting each other.

[0019] Since the first clamping component in the present application is formed with a first notch and the second clamping component is formed with a second notch, when the first clamping component and the second clamping component are in a docked state, a positioning space for accommodating the bolts on the pipe segment can be formed, and under the action of the first elastic member and the second elastic member, when the bolts on the pipe segment enter the positioning space, the bolts can be clamped, thereby achieving clamping, positioning and lifting of the pipe segment.

[0020] It is understandable that during the lifting process, the lifting equipment can be connected to the beam to achieve the lifting and transportation of the pipe segment.

[0021] During actual assembly, after the crossbeam is connected to the lifting device, the lifting device moves the crossbeam in the direction of the bolts close to the pipe segment until it contacts the sides of the first clamping assembly and the second clamping assembly. When the bolts contact the first clamping assembly and the second clamping assembly, as the lifting device continues to move, the bolts can push the first clamping assembly and the second clamping assembly apart, that is, the first clamping assembly and the second clamping assembly can move away from each other, compressing the first elastic member and the second elastic member.

[0022] When the bolt reaches the positioning space formed by the first notch and the second notch, the first elastic member and the second elastic member rebound, causing the first clamping assembly and the second clamping assembly to move toward each other, thereby clamping the bolt on the pipe segment and realizing the assembly of the overall clamping mechanism and the pipe segment.

[0023] Since the connection process between the pipe segment and the clamping mechanism in the present application does not require manual alignment and insertion, the operation efficiency can be greatly improved. In addition, the bolts of the pipe segment are clamped by the first notch and the second notch forming a positioning space, which can also improve the adaptability to pipe segment bolts of different sizes to a certain extent, making the overall equipment more versatile.

[0036] like Figure 1-Figure 9 As shown, the present invention provides a shield tunnel segment 5 hoisting device, including a positioning mechanism and a clamping mechanism; the positioning mechanism includes a crossbeam 1, and the crossbeam 1 is formed with a guide portion 1011 extending along the length direction of the crossbeam 1; the clamping mechanism includes a positioning rod 2, a first elastic member 202, a second elastic member 203, a first clamping assembly 3 and a second clamping assembly 4, the positioning rod 2 is connected to the crossbeam 1 along the length direction of the crossbeam 1, and the positioning rod 2 is located in the guide portion 1011; the first clamping assembly 3 and the second clamping assembly 4 are both The first clamping component 3 is slidably arranged on the positioning rod 2, and a first notch 3031 is formed on the first clamping component 3, and a second notch 4031 is formed on the second clamping component 4. The first elastic member 202 and the second elastic member 203 are both sleeved on the positioning rod 2, and the first elastic member 202 is located between the first clamping component 3 and one end of the guide portion 1011, and the second elastic member 203 is located between the second clamping component 4 and the other end of the guide portion 1011, so that the first notch 3031 is connected to the second notch 4031 to form a positioning space.

[0037] Compared with the prior art, the shield tunnel segment 5 hoisting equipment provided by the present invention has the following advantages: The shield tunnel segment 5 hoisting device provided by the present invention can provide a mounting base for the positioning rod 2 through the crossbeam 1, and can accommodate and limit the moving track of the first clamping assembly 3 and the second clamping assembly 4 through the guide portion 1011 formed along the length direction of the crossbeam 1. It can be understood that, since the first elastic member 202 and the second elastic member 203 in the present application are both sleeved on the positioning rod 2, and the first elastic member 202 is located between the first clamping assembly 3 and one end of the guide portion 1011, and the second elastic member 203 is located between the second clamping assembly 4 and one end of the guide portion 1011, therefore, one end of the first elastic member 202 and one end of the second elastic member 203 can abut against the guide portion 1011, and the other end abuts against the corresponding first clamping assembly 3 and second clamping assembly 4, so that the first elastic member 202 and the second elastic member 203 can always keep the first clamping assembly 3 and the second clamping assembly 4 in a state of abutting each other.

[0038] Since the first clamping component 3 in the present application is formed with a first notch 3031 and the second clamping component 4 is formed with a second notch 4031, when the first clamping component 3 and the second clamping component 4 are in a docked state, a positioning space for accommodating the bolt 501 on the pipe segment 5 can be formed, and under the action of the first elastic member 202 and the second elastic member 203, when the bolt 501 on the pipe segment 5 enters the positioning space, the bolt 501 can be clamped, thereby realizing the clamping, positioning and lifting of the pipe segment 5.

[0039] It can be understood that, during the lifting process, the lifting equipment can be connected to the crossbeam 1 , so as to achieve the lifting and transportation of the pipe segment 5 .

[0040] During actual assembly, after the cross beam 1 is connected to the lifting equipment, the lifting equipment moves the cross beam 1 in the direction of the bolt 501 close to the pipe segment 5 until it contacts the side of the first clamping assembly 3 and the second clamping assembly 4. When the bolt 501 contacts the first clamping assembly 3 and the second clamping assembly 4, as the lifting equipment continues to move, the bolt 501 can push the first clamping assembly 3 and the second clamping assembly 4 apart, that is, the first clamping assembly 3 and the second clamping assembly 4 can move away from each other, compressing the first elastic member 202 and the second elastic member 203.

[0041] When the bolt 501 reaches the positioning space formed by the first notch 3031 and the second notch 4031, the first elastic member 202 and the second elastic member 203 rebound, causing the first clamping assembly 3 and the second clamping assembly 4 to move toward each other, thereby clamping the bolt 501 on the pipe segment 5 and realizing the assembly of the overall clamping mechanism and the pipe segment 5.

[0042] Since the connection process between the pipe segment 5 and the clamping mechanism in the present application does not require manual alignment and insertion, the operation efficiency can be greatly improved. In addition, the bolts 501 of the pipe segment 5 are clamped by the first notch 3031 and the second notch 4031 to form a positioning space, which can also improve the adaptability to bolts 501 of pipe segments 5 of different sizes to a certain extent, making the overall equipment more versatile.

[0043] Preferably, if Figure 1-Figure 3 As shown, the side edges of the first clamping block 303 and the second clamping block 403 in the present application are both guide bevel edges 3032, and after the first clamping block 303 and the second clamping block 403 are attached, the guide bevel edges 3032 of the first clamping block 303 and the second clamping block 403 form a V shape.

[0044] Since the clamping mechanism provided in the present application moves from the side of the bolt 501 of the pipe segment 5 to the direction close to the bolt 501 during actual operation, by making the side edges of the first clamping block 303 and the second clamping block 403 both serve as guiding bevel edges 3032, the first clamping block 303 and the second clamping block 403 can be connected to form a V-shaped guiding structure, so that during the approach process, no matter whether the bolt 501 contacts the first clamping block 303 or the second clamping block 403 first, it can push the first clamping block 303 or the second clamping block 403 to move, thereby opening the positioning space and finally achieving the purpose of entering the positioning space and clamping the bolt 501 by the first clamping block 303 and the second clamping block 403.

[0045] It can be understood that the bolt 501 in the present application includes an end portion and a rod portion, and the diameter of the end portion is larger than the diameter of the rod portion and larger than the diameter of the positioning space, so that after clamping, the end portion with a larger diameter can ensure that the first clamping block 303 and the second clamping block 403 can stably clamp and lift the bolt 501.

[0046] It should be noted here that the first clamping block 303 and the second clamping block 403 in the present application are approximately triangular structures, and rolling structures such as balls can be further installed on the two oblique sides of the first clamping block 303 and the second clamping block 403, so that when contacting the bolt 501, the sliding friction can be converted into rolling friction, making the rod of the bolt 501 smoother in the process of entering the positioning space.

[0047] It should be further explained here that in the present application, the first elastic member 202 and the second elastic member 203 are both pressure springs, and the pressure springs are always in a compressed state. Therefore, in the actual assembly process, when the rod first contacts the first clamping block 303, as the action proceeds, the first clamping block 303 is pushed by the rod, thereby further compressing the first elastic member 202, and the space released by the first clamping block 303 will be under the action of the rebound of the second elastic member 203. Therefore, even if the bolt 501 and the positioning space are misaligned during the initial alignment, it will not affect the bolt 501 from finally entering the positioning space, thereby being able to improve the fault tolerance of the overall equipment connection process to a certain extent.

[0048] like Figure 1 As shown, the crossbeam 1 in the present application includes a beam body 101, a first connecting arm 102 and a second connecting arm 103; a guide portion 1011 is formed along the length direction of the beam body 101, and the first connecting arm 102 and the second connecting arm 103 are relatively connected at both ends of the beam body 101 for connecting a lifting device; a first through hole 1012 and a second through hole 1013 connected to the guide portion 1011 are also formed at both ends of the beam body 101, and the clamping mechanism also includes a fastener 201, and both ends of the positioning rod 2 are respectively connected to the fastener 201 through the first through hole 1012 and the second through hole 1013.

[0049] The two ends of the beam body 101 provided in the present application can be directly connected to the lifting equipment, and the connection can be achieved by directly welding lifting ears at the two ends of the beam body 101. The present application further adds a first connecting arm 102 and a second connecting arm 103 at both ends of the beam body 101, which can increase the distance between the lifting equipment and the beam body 101 to a certain extent, thereby providing sufficient space for the connection between the lifting equipment and the crossbeam 1, avoiding interference with the beam body 101.

[0050] The first connecting arm 102 and the second connecting arm 103 can be connected to the beam body 101 by welding, but the present application preferably adopts flanges to be installed at the ends of the first connecting arm 102 and the second connecting arm 103 and the ends of the beam body 101. On the one hand, the contact area can be increased, and on the other hand, multiple bolts 501 connecting parts can be arranged around the flange to achieve a detachable connection between the first connecting arm 102 and the second connecting arm 103 and the beam body 101.

[0055] Alternatively, if Figure 5As shown, the first movable block 302 and the second movable block 402 in the present application further include a plurality of rollers 304 , which are distributed circumferentially along the first mating portion 3022 and the second mating portion 3023 , and the rollers 304 can roll relative to the first mating portion 3022 and the second mating portion 3023 .

[0058] Furthermore, if Figure 6-Figure 9As shown, the first clamping assembly 3 in the present application also includes a first limiting nail 310, and the second clamping assembly 4 also includes a second limiting nail 408; the first limiting nail 310 is connected to the first clamping block 303, and the second limiting nail 408 is connected to the second clamping block 403, and the axis of the first limiting nail 310 is perpendicular to the first clamping block 303, and the axis of the second limiting nail 408 is perpendicular to the second clamping block 403; the first limiting nail 310 and the second limiting nail 408 both include an end portion 3101 and a guide rod portion 3102, and the diameter of the end portion 3101 is The beam body 101 is larger than the diameter of the guide rod portion 3102. A first guide hole 1015 and a second guide hole 1016 are formed at the bottom of the beam body 101 and along the length direction of the beam body 101. The size of the first guide hole 1015 is adapted to the diameter of the end portion 3101. The size of the second guide hole 1016 is adapted to the diameter of the guide rod portion 3102.

The diameters of the first expansion portion 1017 and the second expansion portion 1018 are adapted to the diameter of the end portion 3101.

[0059] In the present application, the ends of the first connecting rod 305 and the second connecting rod are both formed with abutment parts, and the diameter of the abutment parts is larger than the diameter of the rod body. When the bolt 501 of the pipe segment 5 enters the positioning space for lifting, the end of the bolt 501 abuts against the first clamping block 303 and the second clamping block 403, pulling the first clamping block 303 and the second clamping block 403 downward, so that the abutment part of the first connecting rod 305 is embedded in the first alignment hole 3011 of the first positioning seat 301, and the abutment part of the second connecting rod is embedded in the third alignment hole of the second positioning seat 401. The abutment part in the present application can be a polygonal structure, and accordingly, the shapes of the first alignment hole 3011 and the third alignment hole are adapted to the abutment part, so that the first connecting rod 308 and the second connecting rod 406 can be prevented from being damaged due to the rotation of the first connecting rod 305 and the second connecting rod to a certain extent.

[0060] When the first clamping block 303 and the second clamping block 403 are pulled downward by the bolt 501 of the tube plate 5, the first limiting nail 310 and the second limiting nail 408 can be driven downward, so that the end portion 3101 of the first limiting nail 310 can enter the first expansion portion 1017, and the end portion 3101 of the second limiting nail 408 can enter the second expansion portion 1018, thereby realizing the limitation of the first clamping component 3 and the second clamping component 4 in the length direction of the beam body 101.

[0061] After the lifting and transportation is in place, the lifting equipment drives the clamping mechanism to move downward. When the first limit piece 306 and the second limit piece 404 contact the pipe segment 5, the abutment portion can be moved upward through the first connecting rod 305 and the second connecting rod. Since one end of the first connecting rod 308 is rotationally connected to the abutment portion of the first connecting rod 305, and the other end is rotationally connected to the second sleeve 405, and one end of the second connecting rod 406 is rotationally connected to the abutment portion of the second connecting rod, the first connecting rod 308 and the second connecting rod 406 can be used to make the first sleeve 307 and the second sleeve 405 move away from each other, thereby making the first clamping assembly 3 and the second clamping assembly 4 move away from each other, releasing the clamping of the bolt 501 of the pipe segment 5, and then using the lifting equipment to pull the clamping mechanism to move horizontally, so that the clamping mechanism is separated from the bolt 501 area of ​​the pipe segment 5, and the lifting and transportation of the pipe segment 5 is completed.

[0062] Preferably, if Figure 6 As shown, the first clamping assembly 3 in the present application also includes a third elastic member 309, and the second clamping assembly 4 also includes a fourth elastic member 407; the third elastic member 309 is sleeved on the first connecting rod 305 and is located between the first clamping block 303 and the first limiting member 306; the fourth elastic member 407 is sleeved on the second connecting rod and is located between the second clamping block 403 and the second limiting member 404.

[0063] When the first limiting member 306 and the second limiting member 404 are in contact with the pipe segment 5, the third elastic member 309 and the fourth elastic member 407 are compressed, thereby pushing the first clamping block 303 and the second clamping block 403 to move upward, thereby driving the first limiting pin 310 and the second limiting pin 408 to move upward, and causing the end portion 3101 of the first limiting pin 310 and the end portion 3101 of the second limiting pin 408 to move upward, disengaging from the first expansion portion 1017 and the second expansion portion 1018, thereby unlocking the positions of the first clamping block 303 and the second clamping block 403.

[0064] More preferably, if Figure 1 As shown, a first lifting ear portion 1021 is formed at one end of the first connecting arm 102 away from the beam body 101 in the present application, and a second lifting ear portion 1031 is formed at one end of the second connecting arm 103 away from the beam body 101 .

[0065] By utilizing the first lifting ear portion 1021 and the second lifting ear portion 1031, a quick and detachable connection between the clamping mechanism and the lifting device can be achieved, thereby facilitating lifting.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
