Description

Technical Field

[0001] The utility model relates to the technical field of tire gantry crane equipment, in particular to a tire gantry crane. Background Art

[0002] A tire gantry crane refers to a gantry crane (full name gantry crane) that uses a tire chassis for movement. A gantry crane is a variation of a bridge crane. In ports, it is mainly used for loading and unloading operations in outdoor cargo yards, material yards, and bulk cargo.

[0003] Most common tire gantry cranes are hoisted directly by electric hoists. Since the tire gantry crane is large in size, the steel cable extended by the electric hoist is long when hoisting the cargo, which makes it easy for the cargo to shake during the hoisting process. Especially in windy weather, the cargo and the tire gantry crane are connected by a long steel cable. The amplitude and difficulty of the cargo shaking will be affected by the length of the steel cable. The longer the rope, the easier it is to shake and the greater the shaking amplitude. When lifting, the cargo will shake more violently due to the influence of wind force. The violent shaking will affect the stability of the entire tire gantry crane, and in severe cases, the steel cable will be separated from the cargo.

[0004] Therefore, a tire gantry crane is proposed to solve the above-mentioned problems. Utility Model Content

[0005] Based on the above description, the utility model provides a tire gantry crane to solve the problem that the cargo is easy to shake due to the steel cable being too long during the lifting process.

[0006] The utility model provides a technical solution to the above-mentioned technical problems as follows: a tire gantry crane, comprising: a gantry crane body and guide limit columns, the guide limit columns are arranged inside the gantry crane body, the total moving frame is arranged between the guide limit columns, and comprises a vertical moving frame, a transverse moving frame and a locking mechanism, the transverse moving frame is arranged between the vertical moving frames, the locking mechanism is arranged inside the vertical moving frame, and comprises a clamping hoop, a moving block and an electric push rod, the clamping hoop is sleeved on the outside of the guide limit columns, and is connected to the output shaft of the electric push rod through the moving block.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the vertical movable frame includes movable blocks, connecting guide rails are arranged between the movable blocks, and adjacent movable blocks are connected to each other by screws and nuts.

[0009] Furthermore, a mounting groove is provided on one side opposite to the movable block, a movable frame is provided inside the mounting groove, and a side roller is provided at the bottom end of the movable block.

[0028] See also Figure 1 , a tire gantry crane, comprising:

[0029] Gantry crane body 1, the gantry crane body 1 is a tire gantry crane, and its specific structure and principle are all existing technologies, so its specific structure and principle are not described in detail here; and

[0030] The guide limit column 2 is arranged inside the gantry crane body 1 , and the guide limit column 2 plays a limiting and guiding role, so that the total moving frame can only move vertically along the guide limit column 2 .

[0031] like Figure 2-Figure 5 As shown, the vertical movable frame 3 includes movable blocks 31, connecting guide rails 32 are arranged between the movable blocks 31, adjacent movable blocks 31 are connected to each other by screws and nuts, a mounting groove 33 is arranged on the opposite side of the movable block 31, a movable frame is arranged inside the mounting groove 33, a side roller 34 is arranged at the bottom end of the movable block 31, the guide limit column 2 is arranged between the movable blocks 31, and the side roller 34 is in contact with the outer surface of the guide limit column 2;

[0032] The transverse moving frame 4 includes a transverse moving frame body 41, and the transverse moving frame bodies 41 at the upper and lower sides are connected to each other by screws and nuts. The two transverse moving frame bodies 41 are respectively arranged at the upper and lower sides of the connecting guide rail 32, and a rope fixing rod 42 is arranged inside the transverse moving frame body 41. The outer surface of the transverse moving frame body 41 is provided with a supporting roller 43, and the supporting roller 43 is in contact with the surface of the connecting guide rail 32;

[0033] Based on the above, through the rope fixing rod 42 inside the transverse moving frame 4, the transverse moving frame 4 can be connected to the rope extended from the electric hoist in the gantry crane body 1, and the transverse moving frame 4 is driven by the rope to move laterally along the direction of the connecting guide rail 32, and the vertical moving frame 3 can be driven to move vertically along the guide limit column 2, wherein the cargo can also be connected to the rope fixing rod 42 through a short rope. Since the rope connecting the transverse moving frame 4 is short, it is not easy to shake and the amplitude after shaking is small.

[0034] like Figure 2 and Figure 3 As shown, the locking mechanism is arranged inside the vertical moving frame 3 and includes a clamping hoop 5, a moving block 6 and an electric push rod 7, wherein:

[0035] A clamping hoop 5, which is sleeved on the outside of the guide limit column 2 and is connected to the output shaft of the electric push rod 7 through a moving block 6. The clamping hoop 5 is arranged inside the mounting groove 33. The clamping hoop 5 includes a semicircular hoop 51, which is hinged to the moving block 6. The semicircular hoop 51 is connected to the connecting member 52 through screws and nuts. The surface of the semicircular hoop 51 close to the guide limit column 2 is provided with a toothed surface 53;

[0036] Based on the above, the locking mechanism plays a role in preventing falling. When the rope of the electric hoist is accidentally detached from the main moving frame, the moving block 6 can be driven by the electric push rod 7 to move in the direction away from the guide limit column 2. At this time, the clamping hoop 5 fits tightly with the surface of the guide limit column 2 after movement. The friction force after close fit is relatively large. Under the action of friction, the impact force when the goods fall can be alleviated, and it can even achieve the effect of preventing the goods from falling.

[0037] In actual use of this embodiment, by connecting the rope extending from the electric hoist of the gantry crane body 1 to the rope fixing rod 42, the rope fixing rod 42 located below can be connected to the goods through the rope. During the hoisting process, the longer part of the rope is the rope between the general moving frame and the electric hoist. This part of the rope that is longer and easy to shake is restricted by the general moving frame and the guide limit column 2, and can only move vertically, that is, it cannot shake.

[0038] The rope connecting the transverse moving frame 4 and the cargo is shorter, so the cargo is less likely to shake during the lifting process and the shaking amplitude is smaller;

[0039] Under the premise of ensuring that the shaking amplitude is small and not easy to shake, the transverse moving frame 4 can move transversely along the direction of the connecting guide rail 32, that is, the goods can move transversely;

[0040] When the rope connecting the electric hoist and the transverse moving frame 4 accidentally falls off, the total moving frame and the goods fall downward together. During the falling process, the electric push rod 7 can be controlled to work, and the electric push rod 7 drives the moving block 6 to move in the direction close to the transverse moving frame 4. At this time, the clamping hoop 5 is tightly fitted with the surface of the guide limit column 2 after being stressed, and the setting of the toothed surface 53 increases the friction force, thereby hindering the falling process of the total moving frame, reducing the impact force during the falling, or directly stopping the falling;

[0041] The tire gantry crane is provided with a total moving frame and a guide limit column 2, thereby reducing the shaking amplitude and increasing the difficulty of shaking. Compared with the traditional tire gantry crane, the stability is stronger, and the locking mechanism makes the crane safer.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
