Description

Technical Field

[0001] This utility model relates to the field of segment hoisting technology, and in particular to a winch-type segment hoisting machine with translation function. Background Technology

[0002] A segment crane is a heavy-duty piece of machinery specifically designed for transporting and installing tunnel segments; it is also known as a tunnel segment transport crane. Segment cranes are commonly used in underground tunnel projects, such as subways, tunnels, and water conservancy projects. Because the on-site environment is often narrow, complex, and challenging, segment cranes need to be adaptable and capable of precise operation within confined spaces.

[0003] Existing segment cranes have a large volume and can only move longitudinally (X-direction) within the tunnel for lifting. This requires manual handling to achieve lateral movement of the segments (Y-direction), which is time-consuming, labor-intensive, and has high labor costs. Utility Model Content

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0035] Reference Figures 1-6 As shown, this utility model embodiment provides a winch-type segment hoist with translation function, comprising:

[0036] The main frame 100 includes a bend 110 located between two tunnel tracks 500;

[0037] The first moving component 200 is connected to the main frame 100 and suspended on the tunnel track 500; the first moving component 200 is configured to drive the main frame 100 to move in the X direction; the X direction is the length direction of the tunnel (i.e. the extension direction of the tunnel track 500); the first moving component 200 drives the entire crane to move along the tunnel track 500.

[0038] The lifting assembly 300 is slidably connected to the underside of the main frame 100; the lifting assembly 300 includes a frame 310 and a plurality of winch components 320 for lifting heavy objects disposed in the frame 310;

[0039] The second moving component 400 is connected to the lifting component 300 and the bending portion 110; the second moving component 400 is configured to drive the lifting component 300 to move in the Y direction, where the Y direction is the width direction of the tunnel; the second moving component 400 includes an electric push rod 410, which is movably connected to the main frame 100, and the output end of the electric push rod 410 is movably connected to the lifting component 300.

[0040] Specifically, in this application, the bent portion 110 of the main frame 100 is located between two tunnel tracks 500. The lifting assembly 300, the second moving assembly 400, and the lifting assembly 300 are all connected to the bottom of the main frame 100. This effectively reduces the spatial volume of the segment crane body and improves the space utilization rate in small-diameter tunnels. Secondly, this application can achieve moving and lifting along the tunnel length direction (X direction) via the first moving assembly 200, and moving and lifting along the tunnel width direction (Y direction) via the second moving assembly 400, thereby meeting the needs of multi-directional lifting, saving time and effort, and reducing labor costs.

[0041] In addition, the output end of the electric push rod 410 of this application is movably connected to the lifting assembly 300, so that when there is a certain height difference between the two ends of the electric push rod 410, it can be adaptively adjusted, thereby ensuring the stability of the connection between the electric push rod 410 and the lifting assembly 300 and the main frame 100; further ensuring that the lifting assembly 300 can be in a horizontal state.

[0042] Furthermore, there are two sets of second moving components 400, located at both ends of the bent portion 110. Specifically, the two sets of second moving components 400 provided in this embodiment make the operation more stable.

[0043] Further, the second moving component 400 includes an I-shaped track 420 disposed at the bottom of the main frame 100 and at least one sliding component 430; the I-shaped track 420 extends in the Y direction; the sliding component 430 includes a connecting body 431 and a plurality of rollers 432 rotatably connected to the connecting body 431; the connecting body 431 is suspended at the bottom of the I-shaped track 420; in some embodiments, there are four rollers 432, arranged front, back, left, and right, with two rollers 432 on one side of the I-shaped track 420. The plurality of rollers 432 are symmetrically arranged on both sides of the I-shaped track 420; the rollers 432 are tactilely connected to the I-shaped track 420. The I-shaped track 420 includes a base plate 421, a middle vertical plate 422, and a top plate 423. The rollers 432 are tactilely connected to the upper surface of the base plate 421. Specifically, in this embodiment, movement is achieved by the tactile connection between the tubular rollers and the I-shaped track 420, resulting in low friction and smooth operation. The I-shaped track 420 is used to guide the lifting assembly 300 to move in the left and right (i.e., Y direction) directions of the tunnel and to bear the weight of the lifting assembly 300.

[0044] In some embodiments, the side of the bent portion 110 is provided with a side welding plate 111, and the side welding plate 111 is threaded with a hole to realize the connection between the main frame 100 and the lifting assembly 300.

[0045] The second moving component 400 also includes a plurality of anti-tipping wheels 440 rotatably connected to the connecting body 431. Further, the plurality of anti-tipping wheels 440 are rolledly connected to the lower surface of the I-beam track 420. In some embodiments, there are four anti-tipping wheels 440, which are rolledly connected to the four corners of the lower surface of the base plate 421 of the I-beam track 420. Specifically, the anti-tipping wheels 440 provided in this embodiment can prevent the second moving component 400 from tilting in the X direction, thereby ensuring the stability of movement.

[0046] Furthermore, the second moving component 400 also includes a plurality of guide wheels 450 movably connected to the side of the connecting body 431; the guide wheels 450 are tactilely connected to the side of the I-shaped track 420. The guide wheels 450 are also tactilely connected to the intermediate vertical plate 422. Specifically, in this embodiment, the guide wheels 450 serve a guiding function, making the movement along the Y direction smoother.

[0047] Furthermore, limiting baffles 424 are provided at both ends of the I-shaped track 420. Specifically, the limiting baffles 424 are used to limit the sliding component 430, preventing the sliding component 430 from detaching from the I-shaped track 420.

[0048] Furthermore, the first moving component 200 includes an active trolley 210; the active trolley 210 is slidably connected to the tunnel track 500, and the active trolley 210 is connected to the main frame 100 via a connecting component 600. Specifically, this embodiment improves the power of movement on the tunnel track 500 through the active trolley 210, resulting in a stable and reliable structure.

[0049] Furthermore, the first moving component 200 also includes a plurality of suspended trolleys 220 connected to the main frame 100; at least one suspended trolley 220 is provided on one side of the tunnel track 500; the suspended trolleys 220 are tumbling connected to the tunnel track 500. Specifically, in this embodiment, the suspended trolleys 220 provide support for the crane to slide on the tunnel track 500 while reducing friction, thereby further improving the smoothness of movement.

[0050] Furthermore, the main frame 100 also includes connecting portions 120 at both ends of the bend 110; the bend 110 is formed by arching upwards from the upper surface of the connecting portion 120; the bend 110 is located between the two tunnel tracks 500, and the lifting assembly 300 is connected to the bend 110; the connecting portion 120 is located below the two tunnel tracks 500, and the first moving assembly 200 is connected to the connecting portion 120. Specifically, this application can better match the spacing of the two tunnel tracks 500, thereby improving the utilization rate of the limited space in the tunnel.

[0051] The connecting part 120 is provided with multiple bearing seats, which are used to connect the suspension trolley 220 and the main frame 100.

[0052] Furthermore, the winch component 320 includes a winch, a wire rope, a pulley block, and a hook; the winch is connected to the frame 310; the wire rope is wound around the winch, and the end of the wire rope passes over the pulley block and is connected to the hook. The winch is responsible for lifting heavy objects. The pulley block provides fixing points for the wire rope. Specifically, the structure of this application is stable and low in cost.

[0053] In some embodiments, the second moving assembly 400 further includes a push rod body 460 and a push rod connecting base 470; one end of the electric push rod 410 is hinged to the push rod connecting base 470, and the push rod connecting base 470 is connected to the side welding plate 111 by bolts. The other end of the electric push rod 410 is connected (hinged) to the push rod body 460. Both ends of the push rod body 460 are connected to the frame 310 by bolts.

[0054] During the segment lifting process of this application, the hook of the winch component 320 is connected to the corresponding lifting device, and the lifting device is connected to the segment being lifted. The segment, the lifting device, and the lifting assembly 300 are relatively stationary on the horizontal plane of the tunnel. The lifting of the segment inside the tunnel is achieved by the winch on the lifting assembly 300.

[0055] The tunnel segment moves along the tunnel track 500 (i.e., the X direction) inside the tunnel. The main frame 100, the lifting assembly 300, and the second moving assembly 400 are relatively stationary on the tunnel track 500. The movement is powered by the motor on the active trolley 210, realizing the longitudinal hoisting of the tunnel segment along the X direction inside the tunnel.

[0056] When the tunnel segment moves laterally (i.e., in the Y direction) within the tunnel, the active trolley 210, the suspension trolley 220, and the main frame 100 are on the tunnel track 500, while the second moving component 400 moves (specifically, the electric push rods 410 of the second moving component 400 extend simultaneously with the connection point between the push rod connecting base 470 and the side welding plate 111 as the fulcrum, driving the lifting component 300 to move laterally, and the sliding component 430 reduces the resistance to the movement of the lifting component 300, ensuring that the electric push rods 410 have sufficient thrust, and driving the lifting component 300 to move on the I-shaped track 420 of the main frame 100, thereby realizing the lateral hoisting of the tunnel segment within the tunnel).

[0057] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
