Abstract
Description
Technical Field
[0001] The utility model relates to a bridge crane paralleling device. Background Art
[0002] In the prior art, there is a requirement for parallel operation between two trolleys or two bridge cranes on a bridge crane. Parallel operation here can also be called interlocking. For example, the parallel operation device of a bridge crane of a hydropower station is used for parallel operation between two bridge cranes of a hydropower station. The parallel operation device mainly consists of three parts: a connecting seat 1, a connecting rod 2 and a nut 3. When two bridge cranes of a hydropower station are switched from independent operation to parallel operation, an operator needs to board the bridge crane to connect the two cranes. Figure 1 The hydropower station bridge crane on the left will Figure 1 The connecting rod 2 on the right side of the hydropower station bridge crane is connected to Figure 1 The connecting seat 1 of the hydropower station bridge crane on the left is connected, and then the nut 3 is tightened to complete the mechanical connection between the two hydropower station bridge cranes. At this time, the two hydropower station bridge cranes can run synchronously. When the two hydropower station bridge cranes need to be converted from synchronous operation to independent operation, the operator is required to board the hydropower station bridge crane to perform the opposite operation. Therefore, the prior art parallel vehicle device requires the operator to frequently get on and off the hydropower station bridge crane for manual operation, which is inconvenient to operate manually. When the weight of the connecting rod is relatively large, multiple workers are required, which is time-consuming and labor-intensive. Therefore, the production cost of the hydropower station bridge crane is increased and the production efficiency is reduced. Utility Model Content

DETAILED DESCRIPTION
[0013] like Figure 1 and 2 As shown, a bridge crane merging device includes a first support 2 and a second support 5 respectively fixedly connected to a main vehicle 1 and an auxiliary vehicle 6, a first oil cylinder 8 and a second oil cylinder 7 are respectively fixedly connected to the first support 2 and the second support 5, an axle seat 3 is fixedly connected to the auxiliary vehicle 6 on one side of the second oil cylinder 7, an axle hole for inserting the piston rod of the second oil cylinder 7 is provided on the axle seat 3, a limit block 4 is assembled on the piston rod of the first oil cylinder 8, and a pin hole for the piston rod of the second oil cylinder 7 to pass through is provided on the limit block 4.
[0014] It also includes a three-position four-way solenoid valve 13. The rodless chambers of the first oil cylinder 8 and the second oil cylinder 7 are connected to the three-position four-way solenoid valve 13A port via a first oil pipe, and the rod chambers of the first oil cylinder 8 and the second oil cylinder 7 are connected to the three-position four-way solenoid valve 13B port via a second oil pipe. A first one-way sequence valve 10 is installed on the first oil pipe connected to the rodless chamber of the second oil cylinder 7, and a second one-way sequence valve 12 is installed on the second oil pipe connected to the rod chamber of the first oil cylinder 8.
[0015] The first oil pipe and the second oil pipe are respectively connected with a pressure relay 9 , the pressure relay 9 is connected to the input end of the controller 11 , and the three-way and four-way solenoid valves are connected to the output end of the controller 11 .
[0016] The working principle of the utility model is as follows: after the start of the paralleling, the controller 11 controls the three-position four-way solenoid valve 13 to switch to the right position, and the hydraulic oil first enters the rodless chamber of the first oil cylinder 8, forcing the piston rod of the first oil cylinder 8 to extend to the limit position. As the oil is continuously fed into the rodless chamber of the first oil cylinder 8, the oil pressure in the rodless chamber of the first oil cylinder 8 also increases. When the pressure exceeds the set pressure of the first one-way sequence valve 10, the first one-way sequence valve 10 opens, and the hydraulic oil enters the rodless chamber of the second oil cylinder 7, forcing the piston rod of the second oil cylinder 7 to extend. The extended piston rod first passes through the pin hole on the limit block 4 and then is inserted into the shaft hole on the axle seat 3. When the oil pressure of the second oil cylinder 7 reaches the limit pressure, the pressure relay 9 on the first oil pipe is triggered. After the controller 11 obtains the signal of the pressure relay 9, it controls the three-position four-way solenoid valve 13 to switch to the middle position to complete the paralleling of the main vehicle 1 and the auxiliary vehicle 6.
[0017] When it is necessary to separate the main vehicle 1 from the auxiliary vehicle 6, the controller 11 controls the three-position four-way solenoid valve 13 to switch to the left position, and the hydraulic oil first enters the rod chamber of the second cylinder 7, driving the piston rod of the second cylinder 7 to be first withdrawn from the axle seat 3 and the limit pin, and then the hydraulic oil passes through the second one-way sequence valve 12 and enters the rod chamber of the first cylinder 8, retracting the piston rod of the first cylinder 8, and finally triggering the pressure relay 9 on the second oil pipe, and the controller 11 controls the three-position four-way solenoid valve 13 to switch to the middle position, completing the separation of the main vehicle 1 and the auxiliary vehicle 6.
