Description

Technical Field

[0001] This utility model belongs to the technical field of beam-moving trolleys, and specifically relates to a beam-moving trolley for beam fabrication yards. Background Technology

[0002] With the rapid development of railway construction and highway infrastructure, the construction tasks at beam fabrication yards are increasing, making the transportation and installation of beams a crucial link. Beam-moving trolleys, as important equipment for transporting and installing box girders, play a vital role. Traditional beam-moving trolley designs are typically customized for different specifications of box girders, with separate designs for single-track or double-track box girders. These traditional trolleys present several problems in use: firstly, single-track and double-track box girders require different trolleys, leading to redundant investment and increased procurement and maintenance costs; secondly, the support distances differ between single-track and double-track box girders, necessitating frequent adjustments or replacements of existing trolleys to accommodate different beam specifications, resulting in cumbersome operation and low efficiency.

[0003] Therefore, designing a beam-moving trolley that can adapt to both single-line and double-line box girders has become an important technical requirement for improving the efficiency of beam fabrication yard operations, reducing equipment investment, and improving operational accuracy. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a beam-moving trolley for beam fabrication yards.

[0005] The technical solution adopted by this utility model is a beam-moving trolley for a beam fabrication yard, including a first trolley and a second trolley arranged symmetrically on the left and right. The first trolley and the second trolley include a frame, a hydraulic lifting device is set at the center of the frame, and a set of wheels is set on the left and right sides of the frame. The frames of the first trolley and the second trolley are connected by a connecting rod. A drive device is set at the end of the frame away from the connecting rod. A support beam is set on the top of the frames of the first trolley and the second trolley. The left and right ends of the support beam are supported and fixed to the upper end of the lifting column of the hydraulic lifting device. Support pads are symmetrically arranged on the upper surface of the support beam. The support pads can be moved to the double-line beam support point on the outside of the support beam to support the double-line beam, or moved to the single-line beam support point on the inside of the support beam to support the single-line beam. The support pads include a pad plate, and baffles are arranged around the pad plate. A rubber pad is set in the space enclosed by the baffles.

[0006] Furthermore, the upper end face of the supporting beam is provided with a first limiting strip of the blocking pad at the double-line beam support position and the single-line beam support position.

[0007] Furthermore, a second limiting strip with a blocking pad is provided on the upper end face of the load beam on the outer side of the double-line beam support position and the inner side of the single-line beam support position.

[0008] Furthermore, a handle is provided on the outer side of the pad.

[0009] Furthermore, the baffle is made of angle steel and welded to the base plate.

[0010] Furthermore, the connecting rod is made of channel steel.

[0011] This utility model has the following beneficial effects:

[0012] 1. Through redesign, this beam-moving trolley can adapt to the transportation of single-line and double-line box girders. The equipment has strong compatibility and does not require the separate purchase and maintenance of multiple specifications of beam-moving trolleys, thus reducing equipment investment costs.

[0013] 2. By setting adjustable support pads, the beam-moving trolley can quickly adapt to box girders with different support point distances, reducing equipment replacement and adjustment time and improving work efficiency.

[0014] 3. This beam-moving trolley is equipped with limit strips and blocking pads on the beam to ensure the stability of the beam during transportation, reduce the risk of accidents, and ensure the safety of the operation.

[0015] 4. Since the beam-moving trolley can be used with both single and double-track box girders, it avoids the duplication of equipment investment and waste of resources, thereby optimizing equipment management on the construction site and improving the efficiency of resource utilization.

Detailed Implementation

[0022] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a beam-moving trolley for beam fabrication yards.

[0023] like Figures 1-3 As shown, a beam-moving trolley for a beam fabrication yard includes a first trolley 1 and a second trolley 2 arranged symmetrically on the left and right. The first trolley 1 and the second trolley 2 include a frame 3. A hydraulic lifting device 4 is set at the center of the frame 3. Wheel sets 4 are set on the left and right sides of the frame 3. The frames 3 of the first trolley 1 and the second trolley 2 are connected by a connecting rod 9. A drive device 6 is set at the end of the frame 3 away from the connecting rod 9. A support beam 7 is set on the top of the frame 3 of the first trolley 1 and the second trolley 2. The left and right ends of the support beam 7 are supported and fixed to the upper end of the lifting column of the hydraulic lifting device 4. Support pads 8 are symmetrically arranged on the upper surface of the support beam 7. The support pads 8 can be moved to the double-line beam support point 71 on the outside of the support beam 7 to support the double-line beam, or moved to the single-line beam support point 72 on the inside of the support beam 7 to support the single-line beam. The support pads 8 include a pad plate 81. The pad plate 81 is surrounded by baffles 82. A rubber pad 83 is set in the space enclosed by the baffles 82.

[0024] In this embodiment, a 900t wheel-rail type beam-moving trolley is modified. This trolley is electrically driven and hydraulically lifted, suitable for current 900t double-track box girders, with a support point distance of approximately 4409mm. This trolley modification needs to adapt to the displacement conditions of both single and double-track box girders. To meet the needs of both double-track and single-track operation, the position of the drive device 6 is adjusted, and a support beam 7 is added. The support beam 7 simultaneously sets up a double-track beam support point 71 (distance approximately 4409mm) and a single-track beam support point 72 (distance approximately 2600mm).

[0025] The support beam 7 is a frame structure. A clamping plate 41 is installed at the upper end of the lifting column of the hydraulic lifting device 4. This clamping plate 41 is bolted to the bottom side plate of the support beam 7. The connecting rod is made of C16 or C20 channel steel and is temporarily welded to connect the first vehicle 1 and the second vehicle. Two handles 811 are respectively installed on the front and rear outer sides of the pad 81. The baffle 82 is made of angle steel and welded to the pad 81.

[0026] The upper end face of the support beam 7 is provided with a first limiting strip 73 of the blocking pad 81 at the double-line beam support position 71 and the single-line beam support position 72. The upper end face of the support beam 7 is provided with a second limiting strip 74 of the blocking pad 81 at the outer side of the double-line beam support position 71 and the inner side of the single-line beam support position 72.

[0027] like Figure 4 and Figure 5As shown, when it is necessary to transport a double-line beam, the support pad 8 can be moved to the double-line beam support position 71 by using the handle 811. When it is necessary to transport a single-line beam, the support pad 8 can be moved to the single-line beam support position 72 by using the handle 811.
