Description

Technical Field

[0001] The utility model relates to the technical field of subway construction, in particular to a subway track laying device. Background Art

[0002] The subway is a fast, high-capacity, electrically-driven rail transit system built in cities. Trains run on fully enclosed lines. Lines in the central urban area are basically located in underground tunnels, and lines outside the central urban area are generally located on viaducts or on the ground. The subway is an exclusive, high-density, high-capacity urban rail transit system covering various underground and above-ground right-of-way areas in urban areas. Special subway track laying equipment is required when laying subway tracks.

[0003] The patent document with announcement number CN218203631U discloses a subway track laying device, including a rail transport frame, and also including an adjustment component detachably mounted on the top of the rail transport frame and a pushing component detachably mounted on the bottom of the adjustment component. The bottom of the rail transport frame is detachably mounted with support columns arranged side by side, and a rotating shaft is rotatably connected between the side walls of the support columns. The outer periphery of the rotating shaft is sleeved and fixed with a track roller located on the inner side of the support column. The side wall of the rail transport frame is constructed with a horizontal groove, and a third screw rod is rotatably connected in the horizontal groove. The outer periphery of the third screw rod is threadedly connected to a sliding block symmetrically arranged and slidably connected in the horizontal groove, and the side wall of the sliding block is mounted with a rail guide frame.

[0004] The device pushes one end of the rail to slide out along the rail guide frame. However, during the sliding process, the rail rubs against the sleepers on the ground, which easily causes wear of the rail and the sleepers. Since the position of the guide frame is fixed, it is not easy to adjust the laying position. Therefore, a subway track laying device is proposed to solve the above problems. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a subway track laying device with the advantages of easy track laying and convenient adjustment. It solves the problem that the existing subway track laying device pushes one end of the rail to make it slide out along the rail guide frame, but the rail rubs against the sleepers on the ground during the sliding process, which easily causes wear of the rail and the sleepers. Since the position of the guide frame is fixed, it is not easy to adjust the laying position.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a subway track laying device, comprising two support seats, a crossbeam is provided above the two support seats, a moving mechanism is provided on the outer side of the crossbeam, and a lifting mechanism is provided between the crossbeam and the support seats;

[0007] The moving mechanism includes a mounting plate slidably mounted on the outside of the beam, an electric hoist and a drive motor are fixedly mounted on the outer wall of the mounting plate, a hanging plate is connected to the lower side of the electric hoist, a grabbing mechanism is provided on the lower side of the hanging plate, a transmission gear is fixedly mounted on the output shaft of the drive motor, a fixed rack is meshed with the outer side of the transmission gear, and the fixed rack is fixedly connected to the outer wall of the beam;

[0008] The grabbing mechanism comprises two electric push rods hinged at the bottom of the hanging plate and two clamping claws rotatably mounted at the bottom of the hanging plate, and the output shafts of the two electric push rods are hinged to the two clamping claws respectively.

[0009] Furthermore, the lifting mechanism includes a hydraulic rod fixedly mounted on the top of the support seat, a connecting plate fixedly mounted on the output shaft of the hydraulic rod, and the crossbeam fixedly connected to the top of the connecting plate.

[0010] Furthermore, a guide wheel is rotatably mounted on the outer wall of the mounting plate, and the traction end of the electric hoist passes through the surface of the guide wheel.

[0011] Furthermore, two hanging ears are fixedly connected to the top of the hanging plate, and the hanging ears are connected to the traction end of the electric hoist.

[0012] Furthermore, two first guide rails are fixedly mounted on the outer wall of the crossbeam, and a first slider is fixedly mounted on the mounting plate at a position close to the first guide rail, and the first slider is slidably engaged with the outer side of the first guide rail.

[0013] Furthermore, two fixing columns are fixedly installed on the outer wall of the support seat, a second guide rail is fixedly installed on the outer wall of the fixing columns, a second slider is fixedly installed at a position of the connecting plate close to the second guide rail, and the second slider slides with the outer side of the second guide rail.

[0014] Furthermore, two movable wheels are rotatably mounted on the bottoms of the two support seats, and the two clamping jaws are symmetrical to each other.

[0015] Compared with the prior art, the present invention provides a subway track laying device with the following beneficial effects:

[0016] 1. The subway track laying device is convenient for grabbing the rails by means of the provided grabbing mechanism. The driving motor drives the transmission gear to rotate, so that the transmission gear moves along the outer side of the fixed rack and drives the mounting plate to slide along the outer side of the first guide rail, thereby driving the rails to move left and right, making it easy to adjust the laying position of the rails. After the laying position is determined, the electric hoist is started to drive the hanging plate to move downward, thereby driving the rails to move downward and place them on the sleepers. The electric push rod is then controlled to release the clamping claws, so that the device can be separated from the rails. The coordinated use of the grabbing mechanism and the moving mechanism makes track laying convenient, avoids the sliding wear of the rails on the sleepers, facilitates the adjustment of the laying position, and improves the efficiency of subway construction.

[0017] 2. The subway track laying device can drive the connecting plate to move downward by activating the hydraulic rod, thereby lowering the overall position of the beam, making it easier to maintain the various components on the beam, thus facilitating maintenance.
