[0002] When working on a construction site, the use of a crane can reduce safety risks such as falls from heights and objects hitting during manual handling. At the same time, when the crane is lifting materials or moving itself, the main function of the crane's anti-collision structure is to prevent collisions, protect the safety of vehicles and passengers, and ensure the safety of the construction process.

[0003] In the prior art, anti-collision structures with elastic effects are usually installed at the front and rear ends and left and right sides of the crane base to achieve the purpose of anti-collision protection of the crane. However, there is a lack of anti-collision protection at the corners of the crane base. When the entire anti-collision structure is actually used, there is a risk that the corners will easily collide with narrow objects, and the overall anti-collision effect of the structure will also be reduced. Therefore, an anti-collision structure for a crane is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-collision structure for a crane, so as to solve the problem in the above background technology that the existing anti-collision structure for a crane lacks anti-collision protection at the corners when in use.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] Preferably, the shape of the corner frame is an "L"-shaped structure, a center card is fixedly connected to the inner corner of the corner frame, the shape of the center card is a fan-shaped structure, and the inner side of the crane base body is provided with a slot that is engaged with the center card.

[0008] Preferably, the corner frame is sleeved on the corners of the crane base body, and the corner frame is fixedly connected to the crane base body by fastening bolts.

[0010] Preferably, the trapezoidal screw is embedded in the interior of the slot and is rotatably connected to the corner frame. The connection between the slider and the limiting buckle plate forms a "T"-shaped structure. The L-shaped brackets are provided in two groups of two, and the center points of the first and second wheels are on the same arc.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-3 , the utility model provides a technical solution:

[0019] A collision prevention structure for a crane comprises an angle clamp frame 1 and a crane base body 12. The outer end surface of the angle clamp frame 1 is provided with two slots 2 which are respectively arranged horizontally and longitudinally. A slider 3 is slidably connected to the inner side of the slot 2. The slider 3 is fixedly connected to a limiting plate 4 at an external position away from the deep part of the slot 2. The upper and lower ends of the limiting plate 4 are respectively fixedly connected to an L-shaped bracket 5. A first rotating wheel 6 is rotatably connected between the upper and lower groups of L-shaped brackets 5. A second rotating wheel 7 is adjacent to the obliquely upper position of the first rotating wheel 6. The inner side of the slider 3 is threadedly connected to a trapezoidal screw rod 8 which passes through the slider 3. The trapezoidal screw rod 8 is fixedly connected to a short shaft rod 9 at an outward position away from the corner of the angle clamp frame 1. The outside of the short shaft rod 9 is fixedly connected to a turning handle 10.

[0020] like Figure 1 and Figure 3 As shown, the shape of the corner clamp frame 1 is an "L"-shaped structure, and a center clamp plate 13 is fixedly connected to the inner corner of the corner clamp frame 1. The shape of the center clamp plate 13 is a fan-shaped structure, and the inner side of the crane base body 12 is provided with a slot that is engaged with the center clamp plate 13. When installing the entire structure, the fit and engagement between the center clamp plate 13 and the crane base body 12 can increase the contact area when the crane base body 12 is connected to the corner clamp frame 1; the corner clamp frame 1 is sleeved on the corners of the crane base body 12, and the corner clamp frame 1 is fixedly connected to the crane base body 12 by fastening bolts 11. This setting will facilitate the entire structure to be able to firmly connect the crane base body 12 and the corner clamp frame 1 through the upper and lower sets of fastening bolts 11.

[0021] like Figure 1 and Figure 2 As shown, the outer diameter of the short shaft rod 9 is smaller than the outer diameter of the trapezoidal screw rod 8, the short shaft rod 9 and the handle 10 are coaxially arranged, and the short shaft rod 9 extends outward through the angle clamp frame 1, which makes it convenient for the operator to adjust the spacing between the second rotating wheel 7 and the first rotating wheel 6 respectively; the trapezoidal screw rod 8 is embedded in the interior of the slot 2 and is rotatably connected to the angle clamp frame 1, and the connection between the slider 3 and the limiting buckle plate 4 forms a "T"-shaped structure. There are two groups of L-shaped brackets 5, each of which is a group of 2. The center points of the first rotating wheel 6 and the second rotating wheel 7 are on the same arc. This setting makes it convenient for the entire structure to use the rotation effects of the first rotating wheel 6 and the second rotating wheel 7 to reduce the direct collision of objects with the corners of the crane.

[0022] Workflow: When the entire anti-collision structure needs to be installed, first, the corner clamp frame 1 is set on the corner position of the crane base body 12 so that the center clamp plate 13 can be fitted and inserted. Then, the center clamp plate 13 and the crane base body 12 can be fixed together by bolt fasteners. Then, the corner clamp frame 1 and the crane base body 12 can be fixed together by two sets of fastening bolts 11 from the lower right and upper left of the corner clamp frame 1, so that the entire structure can be firmly installed. Then, at the same time, a set of trapezoidal screw rods 8 can be rotated toward the corner position of the corner clamp frame 1 through the turning handle 10 and the short shaft rod 9 respectively. The rotation adjustment enables the slider 3 to achieve displacement adjustment with the first rotary wheel 6 or the second rotary wheel 7 toward the corner of the corner frame 1 through the limiting clip 4 and the L-shaped bracket 5, and also directly shortens the distance between the second rotary wheel 7 and the first rotary wheel 6, so that in the subsequent operation of the crane at the construction site, the anti-collision structure composed of the corner frame 1, the slot 2, the slider 3, the limiting clip 4, the L-shaped bracket 5, the first rotary wheel 6, the second rotary wheel 7, the trapezoidal screw 8, the short shaft rod 9 and the handle 10 will provide effective anti-collision protection from the corner positions of the crane base body 12, thereby reducing the number of safety accidents when the crane is in use.

[0023] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
