Description

Technical Field

[0001] This utility model relates to the field of engineering construction equipment technology, and more specifically, to an existing highway steel-concrete composite beam hoisting equipment. Background Technology

[0002] Steel-concrete composite beams typically consist of a steel beam frame and a concrete slab. They are characterized by their heavy weight and complex structure. In modern construction engineering, steel-concrete composite beams are widely used due to their excellent mechanical properties and ease of construction. In highway construction, the hoisting of steel-concrete composite beams is one of the key construction steps, placing high demands on the load-bearing capacity, stability, and precision of the hoisting equipment.

[0003] However, during the hoisting of small-radius steel-concrete composite beams, due to their large curvature, the segmental connection accuracy is difficult to control, easily leading to problems such as misalignment and excessive gaps, affecting the overall stability of the structure and construction quality. Traditional hoisting methods and connection devices are insufficient to meet the high-precision requirements of segmental connections in small-radius steel-concrete composite beams. Utility Model Content

[0004] The purpose of this utility model is to provide an existing highway steel-concrete composite beam hoisting equipment, which can solve the problem of difficulty in controlling the connection accuracy of small-radius steel beam segments during hoisting in the prior art.

[0005] The present invention is implemented through the following technical solution: A hoisting device for existing highway steel-concrete composite beams includes: a connecting assembly, wherein the connecting assembly is disposed at the end of a steel-concrete composite beam segment, and the end of the connecting assembly extends beyond the end of the steel-concrete composite beam segment; the connecting assembly includes a fixed L-shaped plate, which is fixedly disposed at the bottom corner of the steel-concrete composite beam segment; an upper alignment plate and a lower alignment plate are vertically slidably disposed on the fixed L-shaped plate, the upper alignment plate and the lower alignment plate being used to push the upper and lower surfaces of the hoisted steel-concrete composite beam segment to align with the upper and lower surfaces of the segment to be connected; a movable L-shaped plate is slidably disposed at the bottom of the fixed L-shaped plate along the width direction of the steel-concrete composite beam segment, the movable L-shaped plate being used to push the side of the hoisted steel-concrete composite beam segment to align with the side of the segment to be connected.

[0006] Furthermore, a horizontal telescopic cylinder is horizontally arranged on the fixed L-shaped plate, and the piston rod of the horizontal telescopic cylinder is fixedly connected to the movable L-shaped plate.

[0007] Furthermore, two vertical telescopic cylinders are vertically arranged on the fixed L-shaped plate, and the piston rods of the two vertical telescopic cylinders are fixedly connected to the upper alignment plate and the lower alignment plate, respectively.

[0008] Furthermore, a measuring component is provided on the fixed L-shaped plate, which is used to monitor the connection accuracy of the steel-concrete composite beam segments in real time during the hoisting process.

[0009] Furthermore, the measuring components include a laser rangefinder and an angle sensor. The laser rangefinder is used to measure the distance between adjacent steel-concrete composite beam segments, and the angle sensor is used to measure the angular deviation between adjacent segments.

[0010] Furthermore, it also includes a positioning clamp, which is fixed to the side of the steel-concrete composite beam segment by bolts, and the inner side of the positioning clamp is provided with an arc-shaped positioning surface that matches the curvature of the steel-concrete composite beam segment.

[0011] Furthermore, the bottom surface of the positioning fixture is rotatably provided with multiple adjustable support feet to stabilize the position of the steel-concrete composite beam segment during hoisting, and the ends of the support feet abut against the bottom surface of the steel-concrete composite beam segment.

[0012] The technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

[0013] 1. This utility model uses an upper alignment plate and a lower alignment plate to abut against the upper or lower surface of the hoisted steel-concrete composite beam segment and the segment to be connected, and gradually move closer together to align the upper and lower surfaces of the hoisted steel-concrete composite beam segment and the segment to be connected. By using a fixed L-shaped plate and a movable L-shaped plate to move closer together, the left and right surfaces of the hoisted steel-concrete composite beam segment and the segment to be connected are aligned. The two work together to limit the movement range of the hoisted steel-concrete composite beam segment, making the hoisted steel-concrete composite beam segment and the segment to be connected closer together, which is conducive to achieving docking accuracy control during the hoisting process of small-radius steel-concrete composite beams.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] The following description, in conjunction with specific embodiments, provides further details. Figures 1-5 As shown, this utility model is a hoisting equipment for steel-concrete composite beams of existing highways, including a crawler crane 10, a positioning component 20, a connecting component 30, and a measuring component 40.

[0025] Reference Figure 2As shown, the positioning component 20 is installed at the hook of the crawler crane 10. Specifically, the positioning component 20 includes multiple positioning clamps 21. The positioning clamps 21 are fixed to the side of the steel-concrete composite beam segment 50 by bolts. The inner side of the positioning clamp 21 is provided with an arc-shaped positioning surface 22 that matches the curvature of the steel-concrete composite beam. The arc-shaped positioning surface 22 is used to abut against the side of the steel-concrete composite beam segment 50 being hoisted. The arc design of the arc-shaped positioning surface 22 can closely fit the outer surface of the steel-concrete composite beam, ensuring the stability of the segment's position during hoisting. Adjustable support feet 23 are vertically provided at both ends of the positioning clamp 21. The height of the support feet 23 is adjusted by screws to accommodate steel-concrete composite beam segments 50 with different curvatures. Multiple fine-tuning bolts 24 are provided on the arc-shaped positioning surface 22 of the positioning clamp 21. The fine-tuning bolts 24 can fine-tune the fit between the positioning clamp 21 and the steel-concrete composite beam, further improving the positioning accuracy.

[0026] Reference Figure 3 As shown, the connecting assembly 30 is installed at the end of the hoisted steel-concrete composite beam segment 50. The connecting assembly 3021 includes a fixed L-shaped plate 31, an upper alignment plate 32, a lower alignment plate 33, and a movable L-shaped plate 34. The fixed L-shaped plate 31 is located at one of the bottom corners of the steel-concrete composite beam segment 50. The side of the fixed L-shaped plate 31 is fixedly connected to the side of the steel-concrete composite beam segment 50 by bolts, and the bottom surface of the fixed L-shaped plate 31 is fixedly connected to the bottom surface of the steel-concrete composite beam segment 50 by bolts.

[0027] Reference Figure 3 As shown, the upper alignment plate 32 and the lower alignment plate 33 are located on the upper and lower sides of the fixed L-shaped plate 31, respectively. Two vertical telescopic cylinders 35 are installed on the side of the fixed L-shaped plate 31. The piston rods of the two vertical telescopic cylinders 35 are respectively set vertically upward and vertically downward, and the piston rods of the two vertical telescopic cylinders 35 are fixedly connected to the upper alignment plate 32 and the lower alignment plate 33, respectively. During hoisting, the upper alignment plate 32 and the lower alignment plate 33 move closer to each other, pushing the hoisted steel-concrete composite beam segment 50 to align with the upper and lower surfaces of the connecting segment. A guide rod 36 is vertically installed on the side of the fixed L-shaped plate 31. Both the upper alignment plate 32 and the lower alignment plate 33 have guide holes 37, and the guide rod 36 passes through the guide holes 37 to increase the stability of the upper alignment plate 32 and the lower alignment plate 33 relative to the fixed L-shaped plate 31.

[0028] Reference Figure 4As shown, a horizontal telescopic cylinder 38 is installed on the bottom surface of the fixed L-shaped plate 31 along the width direction of the steel-concrete composite beam segment 50. When the piston rod of the horizontal telescopic cylinder 38 is fully extended, the end of the piston rod extends beyond the surface of the steel-concrete composite beam segment 50 on the other side relative to the fixed L-shaped plate 31, and the movable L-shaped plate 34 moves relative to the steel-concrete composite beam segment 50 along the width direction. The piston rod of the horizontal telescopic cylinder 38 is fixedly connected to the bottom surface of the movable L-shaped plate 34, and the longitudinal section of the movable L-shaped plate 34 is L-shaped. When the piston rod of the horizontal telescopic cylinder 38 retracts into the horizontal telescopic cylinder 38, the movable L-shaped plate 34 abuts against the bottom corner of the steel-concrete composite beam segment 50 on the other side relative to the fixed L-shaped plate 31. Both the fixed L-shaped plate 31 and the movable L-shaped plate 34 are arc-shaped, matching the curvature of the steel-concrete composite beam segment 50.

[0029] In this embodiment, along the length of the steel-concrete composite beam segment 50, the fixed L-shaped plate 31, the upper alignment plate 32, the lower alignment plate 33, and the movable L-shaped plate 34 all extend beyond the end of the steel-concrete composite beam segment 50. In this embodiment, the movable L-shaped plate 34 is also equipped with two vertical telescopic cylinders 35, the upper alignment plate 32, and the lower alignment plate 33. The installation structure of the movable L-shaped plate 34 is the same as that of the fixed L-shaped plate 31, and will not be described again here.

[0030] Under the action of the vertical telescopic cylinder 35, the upper alignment plate 32 and the lower alignment plate 33 approach each other to align the upper and lower surfaces of the steel-concrete composite beam segment 50 and the connecting segment, respectively, used for adjusting the hoisting. Under the action of the horizontal telescopic cylinder 38, the fixed L-shaped plate 31 and the movable L-shaped plate 34 approach each other to align the hoisted steel-concrete composite beam segment 50 and the side of the connecting segment. The surfaces of the fixed L-shaped plate 31, the upper alignment plate 32, the lower alignment plate 33, and the movable L-shaped plate 34 are all provided with multiple elastic support pads 39. These elastic support pads 39 provide cushioning during the connection process, reducing accuracy deviations caused by collisions.

[0031] Reference Figure 4 As shown, the measuring component 40 is mounted on the fixed L-shaped plate 31. The measuring component 40 is used to monitor the connection accuracy of the steel-concrete composite beam segments 50 during hoisting. Specifically, the measuring component 40 includes a laser rangefinder 41 and an angle sensor 42. The laser rangefinder 41 measures the distance between adjacent steel-concrete composite beam segments 50, and the angle sensor 42 measures the angular deviation between adjacent segments. Based on the measured data, the measuring component 40 calculates the segment connection accuracy in real time and transmits the measurement data and accuracy information to the construction personnel via a wireless communication module, enabling them to adjust the hoisting and connection operations in a timely manner to ensure the accuracy of the segment connection.

[0032] The working process of this embodiment is as follows:

[0033] In the actual construction process, the positioning clamp 21 is first installed on the middle side of the steel-concrete composite beam segment 50, and the arc-shaped positioning surface 22 of the positioning clamp 21 ensures the stability of the segment's position. Then, the connecting device is installed at the ends of adjacent steel-concrete composite beam segments 50, and the upper alignment plate 32, lower alignment plate 33, and movable L-shaped plate 34 are all kept away from the fixed L-shaped plate 31. Next, the steel-concrete composite beam segment 50 is lifted by the crawler crane 10.

[0034] Reference Figure 1-5 As shown, before hoisting, a crawler crane 10 of suitable size is selected according to the weight of the steel beam to transport the steel box girder from the bridge deck to the hoisting position. During the hoisting process, the steel-concrete composite beam segment 50 is brought close to the connecting segment. The sensors of the measuring component 40 monitor the distance and angle parameters between adjacent segments in real time and send the measurement data to the construction personnel through the wireless communication module, so that the construction personnel can adjust the hoisting height and position and the connection operation in a timely manner to ensure the accuracy of the segment connection.

[0035] The vertical telescopic cylinder 35 and the horizontal telescopic cylinder 38 are activated respectively. The vertical telescopic cylinder 35 moves the upper alignment plate 32 and the lower alignment plate 33 closer together, changing the height difference between the upper and lower surfaces of the hoisted steel-concrete composite beam segment 50 and the connecting segment until their upper and lower surfaces are flush. The horizontal telescopic cylinder 38 drives the moving L-shaped plate 34 closer to the fixed L-shaped plate 31, changing the horizontal distance difference between the hoisted steel-concrete composite beam segment 50 and the connecting segment. The vertical telescopic cylinder 35 and the horizontal telescopic cylinder 38 work together to align the ends of the hoisted steel-concrete composite beam segment 50 with the connecting segment.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
