Description

Technical Field

[0001] This utility model relates to the field of bridge erecting machine technology, and more specifically, to a leveling device for the No. 0 column support leg of a bridge erecting machine. Background Technology

[0002] A bridge erecting machine is a device that uses outriggers to support the bridge beams, thus facilitating the erection of the longitudinal beams of a bridge.

[0003] The existing bridge erecting machine has two outriggers, namely outrigger No. 1 and outrigger No. 0. First, outrigger No. 1 is erected, and then outrigger No. 0 is erected to form temporary support. Outrigger No. 1 is then moved and adjusted to complete the stable support for the bridge erecting machine. However, when erecting the outriggers, construction workers need to stand on the top of the cap beam to observe whether the landing point of the auxiliary outrigger is accurately aligned with the top of the cap beam and whether it is stable after being lowered and needs adjustment. This puts the construction workers at high altitude, which poses a risk to them. Utility Model Content

[0004] The purpose of this utility model is to provide a leveling device for the No. 0 column support leg of a bridge erecting machine, which solves the problem that when the No. 0 column support leg of the bridge erecting machine is being erected, construction workers need to stand on the top of the cap beam to observe the lowering position and stability of the No. 0 column support leg, which poses a risk of working at height for construction workers.

[0005] This utility model is achieved through the following technical solution: This utility model provides a leveling device for the No. 0 column support leg of a bridge erecting machine, including the No. 0 column support leg, an observation camera connected to the middle of the No. 0 column support leg, a UWB ranging sensor set near the top of the No. 0 column support leg, a base set at the bottom of the No. 0 column support leg, leveling columns connected to both sides of the base, a support base connected to the bottom of the leveling columns, a fitting groove set at the bottom of the support base, and a deflection rod hinged to one end of the fitting groove.

[0006] Preferably, the leveling column also includes a ball shaft, which is located at the bottom of the leveling column.

[0007] Preferably, the leveling column is connected to the support base via a bottom ball bearing.

[0008] Preferably, a micro switch is provided at the bottom of the support base, and the micro switch, the observation camera, and the UWB ranging sensor are all connected to the operation terminal signal.

[0009] Preferably, the leveling column is driven by a motor on one side.

[0010] Preferably, the fitting groove further includes a stop block, which is disposed at one end of the middle of the fitting groove, and the side of the stop block facing the fitting groove is inclined.

[0011] Preferably, the deflection rod further includes a deflection shaft and a push block, with the deflection shaft disposed on both sides of one end of the deflection rod and the push block disposed at the end of the deflection rod away from the deflection shaft.

[0012] Preferably, the deflection rod is connected to the fitting groove via a deflection shaft at one end, and the length of the deflection rod is greater than the length of the fitting groove.

[0013] Preferably, the push block is a transverse round rod located at one end of the deflection shaft.

[0014] The technical solution of this utility model has at least the following advantages and beneficial effects: 1. The observation camera and UWB distance sensor installed in the device can accurately control the position of the No. 0 column support leg and its contact with the top of the cap beam, without the need for human assistance in high-altitude operations on the top of the cap beam.

[0015] 2. The device is also equipped with a deflection rod. When the No. 0 column support leg is lowered and contacts the top of the cap beam, pressure is applied to deflect the deflection rod, thereby clearing the corresponding area of ​​the cap beam top and removing debris and stones that may affect the stability of the No. 0 column support leg when it is lowered.

[0023] The following is combined Figures 1 to 6This utility model will be described in detail.

[0024] A leveling device for the No. 0 column support leg of a bridge erecting machine includes a No. 0 column support leg 1, an observation camera 101 connected to the middle of the No. 0 column support leg 1, a UWB ranging sensor 102 near the top of the No. 0 column support leg 1, a base 2 at the bottom of the No. 0 column support leg 1, leveling columns 201 connected to both sides of the base 2, a support base 202 connected to the bottom of the leveling column 201, a fitting groove 2021 at the bottom of the support base 202, and a deflection rod 203 hinged to one end of the fitting groove 2021.

[0025] First, when setting up the bridge erecting machine, the machine is first supported by the No. 1 outrigger and the middle outrigger. Then, the No. 0 column outrigger is moved forward to form a temporary support. Then, the No. 1 outrigger is moved to support the bridge erecting machine, thus completing the stable erection of the bridge erecting machine.

[0026] Furthermore, the leveling column 201 also includes a ball shaft 2011, which is located at the bottom of the leveling column 201. The leveling column 201 is connected to the support base 202 through the bottom ball shaft 2011. A micro switch is provided at the bottom of the support base 202. The micro switch, the observation camera 101, and the UWB ranging sensor 102 are all connected to the operation terminal signal. The leveling column 201 is driven by a motor on one side.

[0027] During the movement and erection of column support leg 1 (0), a UWB distance sensor 102 is used to sense the distance between column support leg 1 and the UWB distance sensor 102 on column support leg 1, thereby precisely controlling the position of column support leg 1 and ensuring accurate displacement to the corresponding cap beam position. Then, column support leg 1 is lowered. During the lowering process, multiple observation cameras 101 are used to observe the lowering of the leveling column 201. When the support base 202 contacts the top of the cap beam, a micro switch is activated to indicate that it has been in contact with the top of the cap beam. At the same time, the UWB distance sensor 102, the observation cameras 101, and the micro switch are all connected to the control terminal, so that the status and data during the operation are displayed on the control terminal. Operation through the control terminal avoids the need for construction personnel to perform high-altitude auxiliary work on the top of the cap beam.

[0028] Meanwhile, if the top of the cap beam has a certain tilt angle, the height of the two support bases 202 can be controlled by driving the leveling column 201 to extend and retract, so as to match the tilt angle of the cap beam. The leveling column 201 is connected to the support base 202 through the ball shaft 2011, which makes it more suitable for the top of the cap beam with a tilt angle.

[0029] Furthermore, the fitting groove 2021 also includes an abutment block 2022, which is located at one end of the middle of the fitting groove 2021. The abutment block 2022 is inclined on the side facing the fitting groove 2021. The deflection rod 203 also includes a deflection shaft 2031 and a push block 2032. The deflection shaft 2031 is located on both sides of one end of the deflection rod 203, and the push block 2032 is located at the end of the deflection rod 203 away from the deflection shaft 2031. The deflection rod 203 is connected to the fitting groove 2021 through one end of the deflection shaft 2031. The length of the deflection rod 203 is greater than the length of the fitting groove 2021. The push block 2032 is a transverse round rod located at one end of the deflection shaft 2031.

[0030] When the support base 202 moves down close to the top of the cap beam, the deflection rod 203 at the bottom will first contact the top of the cap beam. The deflection rod 203 is connected to the fitting groove 2021 through the deflection shaft 2031 at one end. At the same time, due to the restriction of the abutment block 2022, the deflection rod 203 is tilted to one side in the initial state. As the support base 202 moves down, it will squeeze the deflection rod 203 to deflect to one side. Synchronously with the downward movement of the support base 202, one end of the deflection rod 203 will always be in contact with the top of the cap beam during the offset process. Then, due to the deflection, the push block 2032 at one end will move the top of the cap beam that the bottom of the support base 202 is about to contact, so as to push and clear the debris and stones on the top of the cap beam, so as to avoid the presence of foreign objects between the support base 202 and the top of the cap beam, which would affect the fit and support of the support base 202.

[0031] Finally, the length of the deflecting rod 203 is longer than that of the fitting groove 2021. Therefore, after the deflecting rod 203 bends and retracts into the fitting groove 2021, the pushing block 2032 will be on the side of the support base 202, which can also completely push out the debris and stones from the range of the support base 202.

[0032] The following is a detailed implementation process of this utility model. First, when assembling the bridge erecting machine, it is initially supported by support leg 1 and the middle support leg. Then, support leg 0 (1) is moved forward to form temporary support. Support leg 1 is then moved again to support the bridge erecting machine, completing the stable erection of the machine. During the movement of support leg 0 (1), a UWB distance sensor 102 is used to sense the distance between the support leg and the UWB distance sensor 102 on support leg 1, thereby precisely controlling the position of support leg 0 (1) and ensuring accurate displacement to the corresponding cap beam position. Then, support leg 0 (1) is lowered. During the lowering process, multiple observation cameras 101 monitor the lowering of the leveling column 201. Finally, when the support base 202 contacts the top of the cap beam, it activates a microswitch (Honeywell WW series). The system uses a series of sensors to indicate that the beam is aligned with the top of the cap beam. Simultaneously, the UWB ranging sensor 102 (model Anxinke BU01), the observation camera 101, and the micro switch are all connected to the control terminal (model Advantech IPC-610L industrial control computer). The data is then displayed on a tablet for operation, allowing the system to monitor the operation and display data on the control terminal. This avoids the need for construction personnel to perform high-altitude auxiliary work on the top of the cap beam. Furthermore, if the top of the cap beam has a certain tilt angle, the leveling column 201 is extended or retracted to control the height of the two support bases 202, adapting to the tilt angle of the cap beam. The leveling column 201 is connected to the support bases 202 via a ball joint 2011, ensuring a better fit on cap beams with tilt angles.

[0033] When the support base 202 moves down close to the top of the cap beam, the deflection rod 203 at the bottom will first contact the top of the cap beam. The deflection rod 203 is connected to the fitting groove 2021 through the deflection shaft 2031 at one end. At the same time, due to the constraint of the abutment block 2022, the deflection rod 203 is initially tilted to one side. As the support base 202 moves down, it will squeeze the deflection rod 203 to deflect to one side. Synchronously with the downward movement of the support base 202, one end of the deflection rod 203 will always be in contact with the top of the cap beam during the offset process. Then, due to the deflection, it will move, allowing one end to... The pushing block 2032 will move the bottom of the support base 202 to the top of the cover beam that is about to contact, so as to push and remove the debris and stones on the top of the cover beam, so as to avoid the presence of foreign objects between the support base 202 and the top of the cover beam, which would affect the fit and support of the support base 202. Finally, the length of the deflection rod 203 is longer than the fitting groove 2021. Therefore, after the deflection rod 203 bends, deflects and retracts into the fitting groove 2021, the pushing block 2032 will be on the side of the support base 202, which can also completely push the debris and stones out of the range of the support base 202.
