Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction equipment, in particular to an auxiliary device for installing railway box girder supports. Background Art

[0002] At present, domestic railway box girder supports are basically installed using mobile forklifts. Forklifts can assist in the installation of supports. In order to reduce manpower input and reduce potential safety hazards during use, other auxiliary devices are often used to complete the installation work.

[0003] Patent publication number CN117963750A discloses an auxiliary device for the installation of railway box girder supports. In the process of controlling the docking installation of the railway box girder support and the box girder embedded plate, when the height is insufficient, the second cylinder is activated to drive the entire installation plate to rise, thereby driving the upper disc to rise until the railway box girder support and the box girder embedded plate are in contact. When the hole position is inaccurate due to angle reasons, the user can activate the third cylinder to enable the gear rod on its output end to move accordingly. During the process, the slide rail on the back of the gear rod can cooperate with the sliding sleeve to maintain the stability of the movement. Qualitative, and at the same time, the tooth grooves on the surface of the gear rod drive the gear to rotate. Under the action of the connecting shaft, the pad can drive the entire upper disc and the railway box girder support on its surface to rotate until the hole positions are aligned. During the docking and installation of the railway box girder support, since the device does not have a clamping structure, the railway box girder support may shake slightly when it is adjusted, and since the conditions at the construction site are relatively complicated, human collisions may occur, which may cause the railway box girder support that has completed the alignment task to deviate again, requiring the staff to align and adjust the railway box girder support again.

[0004] In view of this, how to improve the stability of railway box girder supports during the docking and installation process of railway box girder supports has become a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0028] Reference Figure 2 One end of the first rotating shaft 4 is rotatably connected to the mounting plate 3 through a bearing (not shown in the figure), and the other end of the first rotating shaft 4 is fixedly connected to a pad 6, and the upper end of the pad 6 is fixedly connected to the turntable 5. The design of the pad 6 increases the stability of the first rotating shaft 4, and is fixedly connected to the turntable 5 to ensure that the turntable 5 does not shake during rotation. The first rotating shaft 4 is fixedly connected to the locking structure.

[0029] Reference Figure 3 The clamping assembly includes a bearing seat 7, a rotating rod 8, a transmission motor 9, a slider 10, a push-pull rod 11 and a clamping plate 12. Both ends of the rotating rod 8 are rotatably connected to the bearing seat 7. Two threaded sections with opposite thread rotation directions are provided on both sides of the rotating rod 8. The bearing seat 7 and the turntable 5 are detachably connected. The output shaft of the transmission motor 9 is transmission-connected to the end of one end of the rotating rod 8. The transmission motor 9 is equipped with a reducer (not shown in the figure). The two opposite threaded sections are threadedly connected to the slider 10. One end of the push-pull rod 11 is hinged to the slider 10, and the other end of the push-pull rod 11 is hinged to the clamping plate 12. The two sets of push-pull rods 11 are equal in length and are arranged in an eight-shaped shape.

[0030] Reference Figure 2The upper end of the mounting plate 3 is detachably connected to a plurality of sleeves 14 in a circular array, and the sleeves 14 are rotatably connected to a plurality of pulleys 15 in a one-to-one correspondence. The pulleys 15 are slidably connected to the lower end of the turntable 5, thereby reducing the friction resistance when the turntable 5 rotates, and the design of the pulleys 15 ensures that the turntable 5 can rotate smoothly.

[0031] Reference Figure 1-2 The side wall of the support frame 1 is fixedly connected to a placing plate 16, and a rotating motor (not shown in the figure) is fixedly connected to the placing plate 16. A connecting rod 17 is provided at the upper end of the placing plate 16 in the vertical direction, and the output shaft of the rotating motor passes through the placing plate 16 and is transmission-connected to the connecting rod 17.

When the pawl 23 is stuck in the tooth groove of the ratchet 22, the spring 25 uses its elastic potential energy to push the pawl 23, thereby preventing the ratchet 22 from continuing to rotate or rotating in the opposite direction, thereby completing the locking task of the first rotating shaft 4. The ratchet structure is a prior art and will not be described in detail here.

[0033] Reference Figure 3 A crash pad 28 is provided on the side wall of the clamping plate 12 facing the blocking plate 13 .

[0035] The working principle of the utility model is as follows: when in use, the staff starts the rotating motor and adjusts the angle of the connecting rod 17 so that the lifting rope 20 connected to the movable rod 18 is located above the railway box girder support to be installed. At this time, the telescopic part 19 is started to drive the lifting rope 20 to move downward, and the staff fixes the railway box girder support through the sling hung on the hook 21, and starts the telescopic part 19 and the rotating motor again to place the railway box girder support on the turntable 5 so that one end of the railway box girder support abuts the side wall of the blocking plate 13, and then starts the transmission motor 9. The two sliders 10 on the opposite threaded sections move relative to each other, and the clamping plate 12 is driven to move toward the direction of the railway box girder support to be installed through the push-pull rod 11. When the anti-collision pad 28 on the clamping plate 12 abuts against the other end of the railway box girder support, the clamping task of the railway box girder support is completed.

[0036] The staff moves the device to the bottom of the box girder embedded plate and locks the device with the wheels 27. In the case of insufficient height, the lifting member 2 is started to drive the installation plate 3 to lift until the railway box girder support and the box girder embedded plate are in contact. When the hole position is inaccurate due to the angle, the staff rotates the turntable 5 to adjust the angle until the hole position is aligned, and then the alignment installation work can be carried out.
