[0007] The inner surface of the adjusting mechanism is fixedly connected with a slider, the interior of the slider is provided with a second screw hole, the outer surface of the adjusting mechanism is provided with a third screw hole, the interior of the third screw hole is threadedly connected with a first bolt;

[0008] A fourth screw hole is provided on the front surface of the reinforcement mechanism, and a second bolt is arranged inside the fourth screw hole.

[0009] Preferably, the lower end of the crane body is fixedly connected to a chassis, the first screw holes are evenly distributed inside the adjustment slot, and the first bolts penetrate the second screw holes and the third screw holes and penetrate into the first screw holes.

[0010] Preferably, the adjustment mechanism is slidably connected to the adjustment slot via a slider, and the adjustment mechanism is fixedly connected to the reinforcement mechanism.

[0011] Preferably, the second bolt thread passes through the fourth screw hole.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model provides a column-type cantilever crane. When in use, the crane body is first installed against a wall or other fixed objects so that the reinforcement mechanism fits the wall or the fixed object as closely as possible. After installation, the adjustment mechanism can be slid through a slider in an adjustment slot according to the height of the wall or the fixed object, and can be slid as high as possible. The higher the height of the adjustment mechanism, the better the reinforcement effect. After the height is adjusted, the first bolt thread can be passed through the second screw hole and the third screw hole and the thread can be inserted into the first screw hole, so that the adjustment mechanism and the reinforcement mechanism are locked and fixed. At this time, the second bolt thread can be passed through the fourth screw hole and inserted into the wall or the fixed object, so that the crane body is fixedly connected to the wall or the fixed object through the reinforcement mechanism, thereby further increasing the firmness of the crane body and preventing safety hazards when lifting heavy objects.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5A column-type cantilever crane comprises a crane body 1, an adjustment mechanism 2 located on the outer surface of the crane body 1 and a reinforcement mechanism 3 located on the front surface of the adjustment mechanism 2, an adjustment groove 12 is provided on the outer surface of the crane body 1, a first screw hole 121 is provided on the bottom surface of the adjustment groove 12, a slider 21 is fixedly connected to the inner surface of the adjustment mechanism 2, a second screw hole 211 is provided inside the slider 21, a third screw hole 22 is provided on the outer surface of the adjustment mechanism 2, a first bolt 23 is threadedly connected to the inner surface of the third screw hole 22, a fourth screw hole 31 is provided on the front surface of the reinforcement mechanism 3, a second bolt 32 is provided inside the fourth screw hole 31, and the crane body 1 is installed against a wall or other fixed objects. The reinforcement mechanism 3 is installed so that it fits the wall or the fixed object as closely as possible. The adjustment mechanism 2 can be slid through the slider 21 in the adjustment slot 12 according to the height of the wall or the fixed object, and can be slid as high as possible. The higher the height of the adjustment mechanism 2, the better the reinforcement effect. After adjusting the height, the first bolt 23 can be threaded through the second screw hole 211 and the third screw hole 22 and threaded into the first screw hole 121, so that the adjustment mechanism 2 and the reinforcement mechanism 3 are locked and fixed. At this time, the second bolt 32 can be threaded through the fourth screw hole 31 and inserted into the wall or the fixed object, so that the crane body 1 is fixedly connected to the wall or the fixed object through the reinforcement mechanism 3, thereby further increasing the firmness of the crane body 1.

[0022] Furthermore, the lower end of the crane body 1 is fixedly connected to the chassis 11, and the first screw holes 121 are evenly distributed inside the adjustment groove 12. The first bolt 23 penetrates the second screw hole 211 and the third screw hole 22 and penetrates into the first screw hole 121. When in use, the first screw hole 121, the second screw hole 211 and the third screw hole 22 are of the same size. By threading the first bolt 23 through the second screw hole 211 and the third screw hole 22 and threading it into the first screw hole 121, the adjustment mechanism 2 can be fixedly locked to the crane body 1.

[0023] Furthermore, the adjusting mechanism 2 is slidably connected to the adjusting groove 12 via a slider 21, and the adjusting mechanism 2 is fixedly connected to the reinforcing mechanism 3. When in use, the adjusting mechanism 2 can be slid via the slider 21 and the adjusting groove 12, thereby adjusting the height of the reinforcing mechanism 3, so that the reinforcing mechanism 3 is suitable for walls or fixed objects of various heights.

[0024] Furthermore, the second bolt 32 is threadedly passed through the fourth screw hole 31 . When in use, the reinforcement mechanism 3 can be fixedly connected to a wall or other fixed objects through the second bolt 32 and the fourth screw hole 31 , thereby increasing the firmness of the crane body 1 .

[0025] Working principle: When installing the crane body 1, the crane body 1 can be fixedly connected to the ground through the chassis 11, and then the crane body 1 is placed close to the wall or other fixed objects so that the reinforcement mechanism 3 fits the wall or fixed object. After the installation is completed, the height of the adjustment mechanism 2 can be adjusted according to the height of the wall or fixed object through the slider 21 inside the adjustment slot 12, and the adjustment mechanism 2 can be slid to the highest possible position, because the higher the height of the adjustment device, the better the reinforcement effect will be. The sliding adjustment mechanism 2 with the adjustment groove 12 can adapt to walls or fixed objects of different heights. After adjusting the height, the first screw hole 121 is passed through the second screw hole 211 and the third screw hole 22 and inserted into the first screw hole 121, so that the adjustment mechanism 2 and the reinforcement mechanism 3 can be locked with the crane body 1. Then, the second bolt 32 is passed through the fourth screw hole 31 and inserted into the wall or fixed object, so as to realize the fixed connection between the crane body 1 and the wall, so as to increase its firmness, avoid safety hazards when lifting heavy objects, and increase the overall practicality.
