Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bridge engineering mobile steel platform beam yard box girder prefabrication construction equipment, and in particular to a track-mounted self-propelled mobile steel platform transverse trolley. Background Technology
[0002] When using mobile steel platforms to precast box girders in a precast box girder plant, the typical construction process is: rebar tying → concrete pouring → box girder curing → tensioning and grouting → girder storage. After the mobile steel platform transports the precast box girder to the storage area, the return trip for the next cycle usually involves using two 10t gantry cranes to lift the mobile steel platform back to the precast platform or using a wired distribution box for the lateral movement of the platform. This presents safety hazards such as hoisting operations and cable wear during the return trip. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model provides a track-mounted self-propelled mobile steel platform transverse trolley.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows:
[0005] A track-mounted self-propelled mobile steel platform traverse trolley includes:
[0006] The traverse trolley track is set laterally at one end of the moving steel platform track;
[0007] A self-propelled traverse trolley is set on a traverse trolley track;
[0008] Several hydraulic jacks are vertically mounted on a self-propelled trolley to lift the lifting legs of the steel platform, thereby enabling the movement of the steel platform.
[0009] The self-propelled traverse trolley includes:
[0010] Several pairs of steel wheels are mounted on the trolley body;
[0011] The drive motor is mounted on the trolley body and connected to the steel wheel spindle via a power transmission mechanism;
[0012] The trolley control box is located on the trolley body and is connected to the start / stop control part of the drive motor.
[0013] This utility model also includes: an infrared limiting device, which is installed at both ends of the trolley body and connected to the trolley control box.
[0014] The beneficial effects of this utility model are:
[0015] 1. This utility model utilizes a return track to the lateral movement zone, and then a DC-powered lateral movement trolley moves laterally to the designated production line, avoiding potential safety hazards. The coordinated action of the movable steel platform, the platform lateral movement zone, and the lateral movement trolley provides a safer solution for the production of precast box girders.
[0016] 2. The main structure of the transverse trolley of this utility model consists of a hydraulic jack, a drive motor, steel wheels, a transverse trolley control box, and an infrared limit device. The self-propelled transverse trolley travels on the transverse trolley track, powered by the drive motor. After the moving steel platform returns to its original position on the track without load, two self-propelled transverse trolleys travel to the underside of the steel platform's lifting legs. The infrared limit device is activated to position the platform. After positioning, the hydraulic jack is raised to the steel platform's lifting legs to lift the moving steel platform. The operator can operate the hydraulic jack and the transverse trolley by operating the remote control. After the self-propelled transverse trolley moves the moving steel platform to the target area, the infrared limit device performs positioning and braking again. After precise stopping, the hydraulic jack descends, and the moving steel platform returns to its position for the next cycle.
[0017] 3. Compared with traditional construction methods, when the steel platform is hoisted to the prefabrication production line, the operators need two 10t gantry cranes to assist in the hoisting. This utility model avoids the safety hazards caused by hoisting operations during the transportation of the mobile steel platform.
[0018] 4. Compared with similar traverse trolleys, this utility model saves more factory space, is easier to operate, and uses DC power, which solves the problems of aging cables and waste of space resources caused by connecting the distribution box to AC power for traverse operations.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0023] like Figure 1 and Figure 2 As shown, a track-driven self-propelled mobile steel platform trolley includes: a trolley track 7, horizontally arranged at one end of a mobile steel platform track 10; a self-propelled trolley 1, arranged on the trolley track 7; and several hydraulic jacks 2, vertically arranged on the self-propelled trolley 1, used to lift the steel platform lifting legs 8 on the mobile steel platform 9, thereby realizing the movement of the mobile steel platform 9. The self-propelled trolley 1 includes: several pairs of steel wheels 4, arranged on the trolley body; a drive motor 5, arranged on the trolley body and connected to the main shaft of the steel wheels 4 through a power transmission mechanism; and a trolley control box 3, arranged on the trolley body and connected to the start / stop control part of the drive motor 5.
[0024] like Figure 1 As shown, this utility model also includes an infrared limiting device 6, which is installed at both ends of the trolley body and connected to the trolley control box 3.
[0025] The car body has a rectangular design, and the main body is welded from 2mm steel plates to ensure its stability and rigidity.
[0026] The trolley body has two hydraulic jacks 2, each with a lifting capacity of 5t and a stroke range of 150-500mm.
[0027] The drive motor 5 has a power of 0.8kw and drives the steel wheels 4 to move on the transverse trolley track 7. The steel wheels 4 consist of two driving wheels and two driven wheels. The self-propelled transverse trolley 1 travels at a speed of 8m / min.
[0028] The infrared limit device 6 is used to brake and position the trolley body. After the moving steel platform 9 returns to the lateral movement area, the self-propelled lateral movement trolley 1 will activate the infrared limit device 6 to automatically brake and position itself when receiving and delivering the moving steel platform 9, so as to ensure the identification and positioning of the moving steel platform 9 by the self-propelled lateral movement trolley 1 and the stopping accuracy of the moving steel platform 9 after lateral movement to the target production line.
[0029] Both the hydraulic jack 2 and the drive motor 5 are operated remotely via the trolley control box 3.
[0030] The self-propelled traverse trolley 1 is powered by a 60V battery pack, which is placed inside the trolley control box 3. A full charge provides continuous operation for approximately 5-7 hours.
[0031] In use, after the mobile steel platform 9 returns to the lateral movement area unloaded, two self-propelled lateral movement trolleys 1 are driven by remote control to the area below the lifting legs 8 of the steel platform. The infrared limiting device 6 automatically identifies and positions the trolleys, aligning the hydraulic jacks 2 with the lifting legs 8. The hydraulic jacks 2 are then operated by remote control to lift the mobile steel platform 9 until it leaves the horizontal ground before lateral movement can begin. When the self-propelled lateral movement trolleys 1 lift the mobile steel platform 9 laterally, attention should be paid to the safety of surrounding personnel. After reaching the target production line, the infrared limiting device 6 automatically identifies the magnetic cone and automatically positions and brakes. After the self-propelled lateral movement trolleys 1 brake to the target production line, the hydraulic jacks 2 are lowered by remote control, allowing the mobile steel platform 9 to naturally fall onto the mobile steel platform track 10. This completes the lateral movement operation, and the cycle begins.
[0032] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
