An anti-tipping gantry crane

Abstract

This utility model provides an anti-tipping gantry crane, including a track parallel to the ground, a ground pole assembly parallel to the track on the ground beside the track, a trolley slidably mounted on the track, outriggers on the top of the trolley, a crossbeam between the tops of two sets of outriggers, a lifting device on the crossbeam, and sliding clamping mechanisms that cooperate with the ground pole assembly at both ends of the trolley. In this utility model, the sliding clamping mechanism is slidably connected to the ground pole assembly through a sliding seat, which enhances the connection stability between the two ends of the trolley and the ground. The sliding seat is not easy to slip off the ground pole assembly, making the crane less prone to instability and tipping. The clamping assembly can clamp and fix the crane to the ground pole assembly, preventing the crane from colliding with the end limit device under wind force and tipping over, thus ensuring its anti-tipping effect.

Description

Technical Field

[0001] This utility model belongs to the field of crane technology, specifically relating to an anti-tipping gantry crane. Background Technology

[0002] Gantry cranes are widely used in freight yards, warehouses, ports, and docks for lifting heavy objects. Gantry cranes typically run on fixed rails, moving the load onto vehicles or ships by moving the crane along the rails. Existing crane braking systems brake the wheels themselves, stopping the crane by preventing them from rotating.

[0003] However, when there are strong winds, especially when the wind force reaches level 8 or above, the wind will blow the crane. At this time, even if the crane's wheels do not roll, they will slide on the track under the force of the wind, causing the crane to move. When the crane reaches the end limit device on the track, the lower wheels stop moving, but the upper part continues to move under the action of inertia, thus causing a rollover accident.

[0004] In the prior art, such as the Chinese utility model patent document with authorization announcement number CN219239063U, an anti-slip and anti-tipping device for a gantry crane is disclosed, in which a hydraulic cylinder drives the rotation of the clamping arm, and the clamping arm drives the rail clamp to clamp the rail; however, excessive clamping force can easily cause damage to the rail surface, affecting the smooth movement of the crane and posing a safety hazard, while insufficient clamping force will affect the anti-tipping effect.

[0005] Therefore, it is necessary to design an anti-tipping gantry crane that can ensure the anti-tipping effect while avoiding damage to the track to solve the current technical problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a gantry crane that can ensure anti-tipping effect while avoiding damage to the track.

[0007] The technical solution of this utility model is as follows: an anti-tipping gantry crane, comprising a track parallel to the ground, a ground pole assembly parallel to the track on the ground beside the track, a trolley slidably mounted on the track, a support leg mounted on the top of the trolley, a crossbeam between the top ends of two sets of support legs, a lifting device mounted on the crossbeam, and sliding clamping mechanisms cooperating with the ground pole assembly at both ends of the trolley; the sliding clamping mechanism has a fixed plate fixedly mounted on the top of the trolley, a sliding seat and a clamping assembly mounted at the bottom of the fixed plate, the sliding seat being slidably connected to the ground pole assembly, and the clamping assembly being used to clamp or release the ground pole assembly.

[0008] Furthermore, the ground pole assembly has a pole body parallel to the track, the slide block has a sliding groove that is slidably fitted on the outside of the pole body, the clamping assembly has clamping blocks corresponding to both sides of the pole body, a clamping arm is fixedly provided on the side of the clamping block away from the pole body, the top end of the clamping arm is hinged to the bottom of the fixing plate, and a hydraulic cylinder is provided on the fixing plate to drive the two clamping arms to move closer or further apart.

[0009] Furthermore, a connecting rod is hinged to the side of the clamping arm near the rod body, and a hinge seat is fixedly provided at the output end of the hydraulic cylinder. The end of the connecting rod opposite to the clamping arm is hinged to the hinge seat.

[0010] Furthermore, a gap of 0.5~1mm is reserved between the slide groove and the rod body.

[0011] Furthermore, a support plate is fixedly provided on the top of the slide block, and the support plate is fixedly connected to the top of the fixed plate.

[0012] Furthermore, a vertical plate is fixedly installed at the bottom of the rod, and a base plate is vertically fixedly installed at the bottom of the vertical plate, with the base plate fixedly installed on the ground.

[0013] The beneficial effects of this utility model are:

[0014] (1) In this utility model, the sliding clamping mechanism is slidably connected between the sliding seat and the ground rod assembly, which strengthens the connection stability between the two ends of the trolley and the ground. The sliding seat is not easy to slip off the ground rod assembly, making the crane less likely to become unstable and tip over.

[0015] (2) The clamping assembly can be clamped and fixed with the ground pole assembly to prevent the crane from falling over due to collision with the end limit device under wind force, thus ensuring its anti-overturning effect;

[0016] (3) The clamping assembly acts on the ground pole assembly and will not damage the track. Attached Figure Description

In addition, the clamping assembly can clamp and fix the ground pole assembly 5, preventing the crane from moving and colliding with the end limit device under the action of wind force and causing a tipping accident, thus ensuring its anti-tipping effect. Furthermore, the clamping assembly acts on the ground pole assembly 5 without causing damage to the track 4.

[0023] In the above embodiment, the fixing plate 61 is fixedly installed on the top of the trolley 3 by welding, which ensures the connection strength between the sliding clamping mechanism 6 and the trolley 3.

[0025] In some embodiments, a connecting rod 66 is hinged to the side of the clamping arm 65 near the rod 52, and a hinge seat 67 is fixedly provided at the output end of the hydraulic cylinder 68. The end of the connecting rod 66 away from the clamping arm 65 is hinged to the hinge seat 56. The hydraulic cylinder 68 drives the hinge seat 67 to move up and down. The hinge seat 67 drives the clamping arm 65 to move closer or further away through the connecting rod 66, thereby clamping or releasing the rod 52.

[0026] In some embodiments, a gap of 0.5 to 1 mm is reserved between the slide 621 and the rod 52; this gap can prevent the slide 62 and the rod 52 from contacting each other during the movement of the crane, thereby preventing them from affecting the movement of the crane.

[0027] In some embodiments, a support plate 63 is fixedly provided on the top of the slide 62, and the support plate 63 is fixedly connected to the top of the fixed plate 61. The slide 62 is fixedly supported on the bottom of the fixed plate 61 by the support plate 63.
