Description

Technical Field

[0001] The utility model relates to the technical field of container lifting and unloading, in particular to a gantry. Background Art

[0002] When using containers to transport goods, you can load the goods directly at the shipper's warehouse and unload them at the consignee's warehouse. When changing vehicles or ships in the middle of the journey, there is no need to take the goods out of the container for reloading. Based on these advantages, container transportation of goods has been widely used. When goods are transported to the terminal destination in a vehicle-mounted container, if there is no special equipment to lift and unload the container, unloading is very troublesome, especially for bulk goods such as ore, which are often handled manually, which is time-consuming and labor-intensive, and has low loading and unloading efficiency.

[0003] In the prior art, a fixed gantry is usually provided to solve the problem of low loading and unloading efficiency. The existing fixed gantry has a large lifting weight and high stability, but poor maneuverability, complex installation, high requirements on ground flatness, and the need to lay special tracks. Utility Model Content

[0004] In view of this, the utility model aims to provide a gantry to facilitate rapid deployment and retraction and improve the maneuverability of the device.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0006] A method includes a mobile platform and a gantry body arranged on the mobile platform; the gantry body includes a lifting arm rotatably arranged on the mobile platform, a crossbeam arm hinged at one end to the lifting arm, and a support arm hinged at the other end of the crossbeam arm, the crossbeam arm is provided with a hook for lifting, and a lifting cylinder is provided between the lifting arm and the mobile platform, a first flipping cylinder is provided between the crossbeam arm and the lifting arm, and a second flipping cylinder is provided between the support arm and the crossbeam arm.

[0007] Furthermore, a connecting rod assembly is provided between the lifting arm and the cross beam arm, and the connecting rod assembly includes a first connecting rod hinged to the lifting arm, a second connecting rod hinged to the cross beam arm, and the first connecting rod is hinged to the second connecting rod.

[0008] Furthermore, one end of the first flip cylinder is hinged to the lifting arm, and the other end of the first flip cylinder is hinged to a hinge point between the first connecting rod and the second connecting rod.

[0009] Furthermore, the support arm includes a support cylinder hinged to the cross beam arm, a telescopic arm slidably arranged on one end of the support cylinder away from the cross beam arm, and a telescopic cylinder arranged between the telescopic arm and the support cylinder.

[0010] Furthermore, the cross beam arm is provided with a first oil cylinder and a moving seat driven by the first oil cylinder and moving along the extending direction of the cross beam arm, the hook is provided on the moving seat, and the moving seat is provided with a first sliding block.

[0011] Furthermore, a first guide rail is provided on the crossbeam arm, and the movable seat is slidably disposed on the first guide rail via the first sliding block.

[0012] Furthermore, the movable seat includes a base slidably arranged on the beam arm, a movable trolley arranged on the base, and a second oil cylinder for driving the movable trolley to move along a direction perpendicular to the extension direction of the beam arm, and the hook is arranged on the movable trolley.

[0013] Furthermore, the movable vehicle includes a base plate and a second sliding block arranged at the bottom of the base plate, and the hook is arranged on the base plate.

[0014] Furthermore, a second guide rail is provided on the base, and the moving trolley is slidably disposed on the second guide rail via the second slider.

[0015] Furthermore, the hook is arranged on the base plate in an adjustable manner up and down.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] The gantry described in the utility model is mainly composed of a lifting arm, a crossbeam arm, a supporting arm, and a hook, and can achieve rapid conversion from a driving state to a working state through the functions of a lifting cylinder, a first flip cylinder, and a second flip cylinder, so that the equipment has a one-key deployment function and can be quickly put into place.

[0018] Secondly, the first connecting rod and the lifting arm, the second connecting rod and the crossbeam arm, and the first connecting rod and the second connecting rod are all connected by hinges, thereby realizing the control of the flip angle between the lifting arm and the crossbeam arm, and improving the flexibility of the equipment. One end of the first flipping oil cylinder is hinged on the lifting arm, and the other end is hinged at the hinge point of the first connecting rod and the second connecting rod, so that the first flipping oil cylinder can drive the first connecting rod and the second connecting rod to rotate when retracting, and then drive the crossbeam arm to approach the lifting arm, making it parallel to the lifting arm, thereby reducing the required space in the height direction of the equipment, which is conducive to realizing a compact layout.

[0019] Furthermore, the setting of the support cylinder can enable the telescopic arm to slide into the support cylinder through the telescopic cylinder, which is conducive to the support arm being built into the crossbeam arm during driving.

The moving seat is slidably arranged on the first guide rail through the first slider, which can avoid shaking during the sliding process. The first guide rail can also play a supporting and guiding role, and can also reduce the friction between the moving seat and the crossbeam arm, thereby extending the service life.

[0020] In addition, the second oil cylinder can control the moving trolley to move in a direction perpendicular to the extension direction of the crossbeam arm, thereby controlling the hook to move. By cooperating with the first oil cylinder, the hook can be moved in the front, back, left, and right directions to accurately lift the container. The moving trolley is arranged on the second guide rail and cooperates with the second slider to ensure that the moving trolley remains stable during the sliding process and avoids shaking of the moving trolley. The hook is arranged on the base plate in an adjustable manner up and down, which is conducive to improving the flexibility of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Here, the gantry is composed of a lifting arm 21, a crossbeam arm 22, a supporting arm 23, and a hook 24. Through the joint action of the lifting cylinder 211, the first flip cylinder 25 and the second flip cylinder 26, the equipment can be quickly converted from a driving state to a working state, so that the equipment has a one-button deployment function and can be quickly put into place.
