Description

crane

The present invention relates to a crane, and more particularly to a crane structure that can lift a ground weight and move it into any floor of a house.

It is known that various high-rise hangers and crane structures that can carry articles up and down are in various forms of clamping components, and the cantilever is clamped and positioned on the wall of the daughter on the top floor, so that the cantilever protrudes out of the parapet wall and is placed at the front end of the cantilever. A steel cable that can be lifted and lowered, a hook is provided at one end of the steel cable, and the other end is connected to the lifting and rotating power unit. In this way, the heavy objects on the ground can be hung on the hook of the steel cable, and then the lifting and rotating power device on the ground is started to pull the steel cable, and the weight is pulled up to the top floor position, and then the cantilever is turned to the top floor. Lift the weight off the ground and place it on the top floor to remove it. With the advancement of the times, various improved forms of high-rise hangers and crane structures have been continuously introduced, such as certificate No. 114486, "Improvement of the base structure of high-rise hangers", which mainly includes components such as a tripod and a lever. The utility model has an inverted L shape, and the top of the lever is pivotally connected to the outer side of the top surface of the tripod, so that the base composed of the tripod and the lever is placed on the top wall of the roof, and the sleeve is provided at the top of the lever for hanging The arm is engaged. When in use, the boom hangs the cargo, and the clamp block provided at the bottom of the ejector pin can be clamped to the wall by the action of the lever, so that the lifting action can be smoothly carried out.

For example, the certificate number M494158 "mechanical transmission boom" includes a column, a cantilever, a sliding seat and a driving device for vertically erecting on the top of a building, the cantilever is laterally disposed and one end is fixed to the The column and the other end extend to the outside of the low wall around the roof, the sliding seat is mounted on the cantilever, and the driving device is connected to the sliding seat, and the sliding seat can be driven to slide back and forth on the cantilever. And a pulley system for hanging heavy objects is mounted on the sliding seat, whereby the worker can move the pulley together with the sliding seat along the cantilever toward or away from the low wall by controlling the driving device. Easy to operate.

The above-mentioned high-rise hangers and crane structures can lift heavy objects from the ground to the top floors, and can achieve the purpose of labor-saving heavy objects. However, if the decoration works are carried out on the floors of the non-top floor, there may be no low walls for the erection due to the site conditions. Or, because the windows on the non-top floor are both walls, even if the high-rise hangers and cranes of the above-mentioned form can be placed on the low walls of the windows, the existing walls will block the rotation of the cantilever. The cantilever that lifts the heavy object is rotated into the floor of the floor. Therefore, the common high-rise hangers and crane structures are only suitable for lifting the heavy objects on the ground to the top floor of the building. Heavy objects are lifted and moved into the floors of the house, which makes the construction and materials inconvenient, and it is necessary to improve.

After the outer side of the opening 159 of the outer wall 157 of the corresponding floor, the rotation of the steel cable 131 (as shown in Fig. 12) is stopped, and the worker can use the hook rod 111 to hook the hole of the hook portion 335. The 337 pulls down, so that the hook plate 319 can rotate the center of the second pivoting member 339, and the groove 331 on the hook plate 319 is disengaged from the blocking lever 177, so that the rotating power device on the ground can be started to take up the steel cable 131. So that the trolley 69 can be displaced on the cantilever 46 toward the second end 50, so that the weight can be lifted Each floor 135 into the interior (as shown in FIG. 16). After the wire take-up cable 131 is stopped and the steel cable 131 is released to remove the weight 135, the pulley 69 is pushed by the hook lever 111 to move the pulley 69 toward the first end 48 of the boom 46, and when the pulley 69 is displaced to the shift lever The 177 contact hook plate 319, the pressing platen 311 and the torsion spring 317 cause the bar 177 to be re-inserted into the recess 331 of the hook plate 319, so that the pulley 69 is again positioned adjacent to the first end 48 of the cantilever 46, so that Carry out the next heavy object 135 lifting work.

In the above operation, the base 22 is also clamped and positioned on the beam 153 of the house by the clamping and positioning device 20, and the end of the cantilever 46 is positioned by the support positioning device 80, so that the cantilever 46 of the crane 10 can be stably installed in the house. In each floor, and by the hook 76 of the pulley 68 provided in the cantilever 46, the steel cable 131 is disposed on the pulley block 60 of the first end 48 of the cantilever 46, so that the rotary power device on the ground starts the coiled steel cable. When the heavy object is lifted to the outside of the opening 159 of the outer wall 157 of the house, the displacement of the trolley 69 can also be operated, so that the weight 135 lifted by the steel cable 131 can enter the room with the trolley 69.

Therefore, it is clear from the above detailed description that the present invention is characterized in that the base 22 is clamped and positioned on the beam 153 of the house by the clamping and positioning device 20, and is positioned at the end of the cantilever 46 by the support positioning device 80, The cantilever 46 of the crane can be stably installed in each floor below the roof of the house, and the steel wrapped around the pulley block 60 of the first end 48 of the cantilever 46 by the hook 76 of the pulley 68 provided in the cantilever 46 The cable 131, or by the suspension arm 46 adjacent to the stop set 179 at the first end 48 and the stop lever 177 on the trolley 69, causes the rotary power unit on the ground to activate the coiled steel cable 131 to lift the heavy object to the wall of the house. When the outside of the opening is used, the lifting operation of the trolley 68 can be utilized to move the lifted weight 135 into the floor room, thereby achieving the practical effect of facilitating lifting and moving heavy objects into the floor of the house.

The basic teachings of this creation have been described in the foregoing paragraphs, and many extensions, variations, or conversions will be apparent to those having ordinary skill in the art, for example, the first portion of the gripping device 20. Only one block 30 is provided on the 24 side and a positioning member 32 is screwed, that is, the positioning member 32 can be rotated to move toward the beam 153 and abut against the side of the beam 153 without setting the two blocks 30 and the two positioning members 32. The base 22 is clamped to the beam 153. Moreover, the outer side of the second portion 26 of the clamping and positioning device 20 is not provided with the side panel 42 , the abutting member 44 and the abutting plate 45 , and the suspension arm 46 can be prevented from holding the first portion 24 of the positioning device 20 , The clamping of the positioning member 32 and the second portion 26, as well as the fixed frame 115 supporting the positioning device 80, provides a stable suspension effect for the cantilever 46.
