Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A bridge maintenance crane includes a base 1, a support column 2 fixedly connected to the surface of the base 1, an adjusting column 3 connected to the surface of the support column 2 via a flange, a mounting frame 4 fixedly connected to the surface of the adjusting column 3, a boom 5 movably connected to the surface of the mounting frame 4, a mounting plate 7 on the surface of the base 1, a support block 71 fixedly connected to the outer surface of the mounting plate 7, a threaded rod 72 penetrating the surface of the support block 71, mounting holes 74 on the surface of the base 1, a sliding groove 75 on the side surface of the mounting plate 7, a control block 76 slidably connected to the inner side of the sliding groove 75, and a fixedly connected... The movable block 73 has a connecting hole 78 on its surface, and a connecting rod 77 is connected to the inside of the connecting hole 78. The movable block 73 has a moving groove 79 on its surface, and a limiting groove 710 is opened on the inside of the moving groove 79. A connecting block 711 is slidably connected to the inside of the limiting groove 710. Through the connection between the base 1 and the support column 2, and the connection between the support column 2 and the adjusting column 3, the support effect of the placement frame 4 and the boom 5 is achieved. The connection angle between the boom 5 and the placement frame 4 is adjusted by a cylinder, and the hoisting is controlled by an electric hoist. This is existing technology and will not be described in detail here.

[0024] Furthermore, an adjusting plate 6 is fixedly connected to the outer surface of the adjusting column 3, and a handle 61 is fixedly connected to the surface of the adjusting plate 6. A through groove is opened through the surface of the adjusting plate 6, and a stop groove 65 is opened on the inner side of the through groove. An insert rod 62 is connected through the through groove on the surface of the adjusting plate 6. A pull plate 63 is fixedly connected to the surface of the insert rod 62, and a stop plate 64 is connected to the outer surface of the insert rod 62. A round hole is opened on the outer surface of the support column 2. Through the connection between the adjusting column 3 and the adjusting plate 6, the adjustment plate 6 can control the rotation of the adjusting column 3 on the support column 2. Through the insertion of the insert rod 62 and the round hole on the support column 2, the angle of action of the adjusting column 3 on the support column 2 is limited and the support effect is achieved.

[0025] Furthermore, the adjusting column 3 consists of two parts, and the two parts of the adjusting column 3 are rotatably connected. The placement frame 4 is rotatably connected to the support column 2 through the adjusting column 3. The mounting plate 7 is plate-shaped and vertically connected to the base 1. Through the connection of the placement frame 4 on the adjusting column 3, the position of the placement frame 4 and the boom 5 is changed under the action of the adjusting column 3, so as to achieve the effect of horizontal adjustment of the hoisted items.

[0026] Furthermore, the insertion rod 62 is inserted through the round holes on the surface of the adjusting plate 6 and the support column 2. The round holes on the surface of the support column 2 are evenly distributed. A spring is connected to the surface of the abutment plate 64. The abutment plate 64 is in contact with the abutment groove 65 through the spring. Through the connection between the insertion rod 62 and the abutment plate 64, the abutment contact between the abutment plate 64 and the abutment groove 65 improves the insertion stability of the insertion rod 62 in the through groove of the adjusting plate 6 and prevents it from falling off on its own.

[0027] Furthermore, the screw 72 passes through the support block 71 and is threadedly connected to the mounting hole 74. The mounting holes 74 are evenly distributed on the surface of the base 1. The mounting plate 7 is connected to the base 1 through the support block 71. Through the connection between the support block 71 and the screw 72, and the connection between the screw 72 and the mounting hole 74, the connection and adjustment of the position of the mounting plate 7 on the base 1 can be achieved.

[0028] Furthermore, the control block 76 has a "T" shaped cross section, and the slide groove 75 has a "T" shaped cross section. The movable block 73 is slidably connected to the mounting plate 7 via the slide groove 75 and the control block 76. The connecting rod 77 passes through the connecting hole 78 and is threadedly connected to the control block 76. Through the connection between the mounting plate 7 and the slide groove 75, the position of the movable block 73 on the mounting plate 7 is adjusted under the sliding connection between the slide groove 75 and the control block 76. Through the connection between the connecting rod 77 and the connecting hole 78, the position of the movable block 73 on the mounting plate 7 is supported and controlled under the insertion of the connecting rod 77 and the control block 76.

[0029] Furthermore, a slider is fixedly connected to the opposite surface of the connecting block 711, and the slider and the limiting groove 710 are slidably connected. The connecting block 711 is slidably connected to the limiting groove 710 and the moving groove 79. A screw hole is opened through the surface of the connecting block 711. With the connection of the movable block 73 and the moving groove 79, the sliding connection between the limiting groove 710 and the connecting block 711 changes the position of the connecting block 711 on the movable block 73, thereby improving the range and performance of the movable block 73 when connected.

[0030] Working principle: When installing and using the crane, first determine the hoisting position, and fix the base 1 with bolts. Then, according to the usage requirements, install the mounting plate 7 on the base 1 at the corresponding position, install bolts on the bridge protection wall surface, rotate the connecting rod 77 to make the control block 76 slide in the slide groove 75, change the action position of the movable block 73 so that it acts on the bolt on the protection wall surface, move the connecting block 711 to connect the connecting block 711 and the bolt, and complete the installation support of the crane. During hoisting, the horizontal angle of hoisting can be changed through the connection of the adjusting plate 6 and the adjusting column 3, thereby increasing the range of hoisting applications. When it is necessary to limit its position, insert the plug rod 62 into the round hole at the corresponding position on the support column 2, thereby completing the operation of limiting the action angle of the adjusting column 3 on the support column 2.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
