Description

Technical Field

[0001] This application relates to the field of crane technology, specifically to a mobile hoisting and shoving device for straddling. Background Technology

[0002] When installing mobile gate hoisting equipment at hydropower stations, it is often carried out on one side of the dam. After installation, when the mobile gate hoisting equipment needs to be moved to the working track in the middle of the dam face, there are often areas or gaps on the dam face that cannot bear pressure. Therefore, when moving the mobile gate hoisting equipment, there is a technical problem that the mobile gate hoisting equipment cannot cross regardless of whether there are tracks on both sides of the gap or the area that cannot bear pressure, or the installation track and the working track are offset by several meters, so the mobile gate hoisting equipment cannot cross the track at an angle. Therefore, a mobile gate hoisting equipment crossing device is needed to enable the mobile gate hoisting equipment to cross gaps and areas that cannot bear pressure.

[0003] For example, a Chinese patent, publication number CN208792159U, publication date April 26, 2019, entitled "A Low-Position Beam Carrying Mechanism," has the following technical solution: A low-position beam carrying mechanism, including a crossbeam, characterized in that it further includes a heavy-duty transporter, a guide wheel assembly, and a support pad; the crossbeam is a connecting beam and a load-bearing beam; the upper ends of the crossbeam are respectively connected to the support pad, and the lower ends are respectively connected to the heavy-duty transporter; the front and rear ends of the heavy-duty transporter are fixed with guide wheel assemblies.

[0004] The aforementioned patents reduce the height of the beam-carrying mechanism to enable beam-carrying across tunnels, but they still cannot cross areas or gaps on the dam surface that cannot bear pressure. Furthermore, for opening and closing devices that already have wheels, additional components such as transfer devices are often not added to solve the technical problem of crossing areas or gaps on the dam surface that cannot bear pressure.

[0012] Furthermore, both ends of the track beam are configured as sloping surfaces to facilitate the entry and exit of mobile opening and closing equipment.

[0013] Furthermore, the track beam also includes a pad; pads are provided between both ends of the track beam and the foundation, and there is a gap between the track beam and the cover plate; the upper surface of the pad is in contact with the track beam, and the lower surface of the pad is in contact with the foundation; the gap between the track beam and the cover plate is 3cm to 6cm.

[0014] Furthermore, the support beam is fixed to the outer side of the lower crossbeam or between two lower crossbeams by welding or bolting.
