Problems solved by technology
The gate adopts the fixed wheel as the walking mechanism, mainly to reduce the opening and closing force during the gate operation process. However, due to the structural limitations of the gate and the deviation of on-site production and installation, the load borne by the gate cannot be evenly distributed to each fixed wheel mechanism. Moreover, the gate is a rigid structure as a whole. During the opening and closing process of the gate, the bearing capacity of the fixed wheel at different positions will change continuously. In order to ensure the safe operation of the equipment, the fixed wheel mechanism can only be designed and manufactured according to the maximum possible load, which greatly increases the equipment load. cost, but also increases the difficulty of manufacturing and installation

Embodiment Construction
[0016] Such as figure 1 As shown in -3, the load-limiting fixed wheel device for the gate of this embodiment is installed between the side beams of the plane gate through bolt connection, the connecting bolts between the fixed wheel and the gate bear the longitudinal load, and the transverse shear load is borne by the shear plate . The fixed wheel device includes a group of runner mechanisms and supporting mechanisms connected by bolts (the number of fixed wheels is determined according to the type, size and load of the plane gate), and a control system installed on the runner mechanism. in:
[0017] The wheel mechanism includes a wheel frame 1, a wheel 2, a wheel shaft 3, a retaining ring 4 and a baffle plate 5. The wheel frame 1 is basically in the shape of an inverted Π, that is, it has a horizontal bottom plate 1-1 and two upright side supports. Plate 1-2, wheel shaft 3 is horizontally installed on both side support plates 1-2, wheel 2 is sleeved on wheel shaft 3, and bo...

The invention relates to a load limiting fixed wheel device for a gate. The invention aims to balance a fixed wheel load and can limit a maximal load of a fixed wheel, such that a carrying capacity of the device is effectively used, the size of a device is reduced, a production cost of the device is reduced and safety performance of the device is improved. A technical solution of the present invention is that the load limiting fixed wheel device for a gate is characterized in that the fixed wheel device comprises a group of rotary wheel mechanisms and support mechanisms which are connected by bolts, as well as control systems mounted on the rotary wheel mechanisms, wherein each rotary wheel mechanism comprises a wheel frame, a wheel, a wheel axle, a check ring and a check plate; each support mechanism comprises a support seat, sealing rubber and a water storage cavity; and the control system comprises an overflow valve, an energy accumulator, a one-way valve, a pressurizing connector and a hydraulic pipeline.
Description
technical field [0001] The invention relates to the field of water conservancy and hydropower engineering, in particular to a load-limiting and fixing wheel device for gates used for gate support. It can balance the fixed wheel load of the multi-fixed wheel support structure gate, or limit the maximum bearing load of the fixed wheel in the double support structure. Background technique [0002] At present, in water conservancy and hydropower projects, the planar fixed wheel gate is a very common water retaining facility, which is often used for working gates and emergency gates, while gates with double support structures are generally used for diversion tunnel sealing gates. [0003] The planar fixed wheel gate refers to the planar water retaining equipment that uses 2 or more sets of fixed wheels as the supporting and running mechanism. The double-support structure gate refers to the planar water-retaining equipment that uses the fixed wheel as the traveling mechanism, and...
