Description

Technical Field

[0001] The utility model relates to the technical field of gantry, in particular to the gantry of a cross-beam type portal crane. Background Art

[0002] The cross-beam type portal crane is a common lifting device, mainly used for loading and unloading operations of goods in ports, docks and other places. Its design feature is that there is a vertical gantry, and a horizontal cross-beam is installed at the top of the gantry. The cross-beam can be single or double, forming a "gate" shape structure. The gantry is one of the key components of the portal crane. It not only supports the weight of the whole crane, but also bears the action of various forces generated when lifting heavy objects.

[0003] At present, for the convenience of movement, small and medium-sized cranes are mostly installed with moving wheels at the bottom end of the crane gantry for movement. After moving to the destination to be lifted, the moving wheels are used to contact the ground, and the stability is poor. Even if wheels with a self-locking structure are set, the effective contact area with the ground is limited, so that the stability is still limited. Based on this, the gantry of the cross-beam type portal crane is proposed here. Content of the Utility Model

[0006] Two movable bottom beams, vertical beams are fixed on the upper end surfaces of the two bottom beams, and a cross-beam is fixed at the top end of the vertical beam;

[0007] A ground supporting component, the ground supporting component includes a movable support plate, and a contact floor is provided at the end of the movable support plate;

[0008] A contraction component, the contraction component includes a convex block and a telescopic rod. The convex block is fixed on the upper end surface of the bottom beam. First accommodation grooves capable of accommodating the movable support plate are opened on both sides of the convex block. One end of the movable support plate is hinged in the first accommodation groove, and the telescopic rod is hinged on the upper end surface of the movable support plate.

[0009] Preferably, the contraction component further includes a second accommodation groove opened on the upper end surface of the movable support plate, and one end of the telescopic rod is hinged in the second accommodation groove.

[0010] Preferably, a limiting groove is opened at the upper end inside the first accommodation groove, and the other end of the telescopic rod can be embedded in the limiting groove.

[0011] Preferably, hinge grooves are opened at the lower ends on both sides inside the first accommodation groove, and the end of the movable support plate is hinged to the hinge grooves through a connecting rod.

[0012] Preferably, anti-slip strips are uniformly fixed on the side of the contact floor that is grounded.

[0013] Preferably, moving wheels are installed at the bottom end of the bottom beam, and a cross beam is provided at the upper end inside the vertical beam.

[0014] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0015] 1. By providing a ground support assembly and a contraction assembly in the present utility model, after the gantry moves to the destination, the ground support assembly can be folded out from the first receiving groove, so that the contact floor installed with anti-slip strips abuts against the ground. Then, the hinged telescopic rod is turned out from the second receiving groove, and the end of the telescopic rod is inserted into the limiting groove, and then the grounded contact floor can be pressed downward to ensure the stability of the gantry after placement.

[0027] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below in conjunction with the accompanying drawings.

[0028] The present invention provides a gantry of a cross-beam type portal crane as shown in Figures 1-5 , including a bottom beam 1, a ground support assembly 6 and a shrinkage assembly 7. There are two bottom beams 1, and moving wheels 3 are installed at the bottom ends of the bottom beams 1. The moving wheels 3 facilitate the movement of the entire gantry. Vertical beams 2 are fixed on the upper end faces of the two bottom beams 1. A cross beam 4 is provided at the upper end inside the vertical beam 2. The setting of the cross beam 4 can improve the overall strength of the vertical beam 2 and the stability of the overall support. And a cross beam 5 is fixed at the top end of the vertical beam 2. The ground support assembly 6 includes a movable support plate 61. A touch floor 62 is provided at the end of the movable support plate 61. Anti-slip strips 63 are uniformly fixed on the side of the touch floor 62 in contact with the ground. When touching the ground, the anti-slip strips 63 contacting the ground can increase the friction force, thereby improving the stability. The shrinkage assembly 7 includes a bump 71 and a telescopic rod 72. The bump 71 is fixed on the upper end face of the bottom beam 1, and preferably the bump 71 is in the middle of the upper end face of the bottom beam 1. First receiving grooves 73 capable of accommodating the movable support plate 61 are opened on both sides of the bump 71. One end of the movable support plate 61 is hinged in the first receiving groove 73. Among them, hinge grooves 76 are opened at the lower ends on both sides inside the first receiving groove 73. The end of the movable support plate 61 is hinged to the hinge groove 76 through a connecting rod. In the initial state, the movable support plate 61 is received in the first receiving groove 73. The telescopic rod 72 is hinged to the upper end face of the movable support plate 61. The telescopic rod 72 can be used to support and resist the movable support plate 61 to touch the ground, and preferably the telescopic rod 72 is a manual telescopic rod, and an existing telescopic rod structure can be adopted.

[0029] Refer to Figure 4 As shown, the shrinkage assembly 7 further includes a second receiving groove 74 opened on the upper end face of the movable support plate 61. One end of the telescopic rod 72 is hinged in the second receiving groove 74. After the telescopic rod 72 retracts, the telescopic rod 72 can be received in the second receiving groove 74, which is beneficial for storage.

[0030] Refer to Figure 5 As shown, refer to Figure 4 As shown, a limiting groove 75 is opened at the upper end inside the first receiving groove 73. The other end of the telescopic rod 72 can be embedded in the limiting groove 75.

[0031] Based on the above technical solutions, during specific use, the movement of the entire gantry can be achieved by using the moving wheels 3. When the gantry is moved to the required position, the staff can fold out the ground support component 6 from the first receiving groove 73, so that the contact floor 62 equipped with the anti-slip strip 63 contacts the ground. Then, the hinged telescopic rod 72 is folded out from the second receiving groove 74. Subsequently, the telescopic rod 72 is extended, and then the end of the telescopic rod 72 is inserted into the limiting groove 75, and then the contact floor 62 in contact with the ground can be pressed downwards to ensure the stability of the gantry.

[0032] When movement is required, the telescopic rod 72 can be received into the second receiving groove 74, and the ground support component 6 can be received into the first receiving groove 73, and then the whole can be received, which is convenient for storage.

[0033] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
