Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The existing inverted hoist can realize the function of automatic turnover, but because the hoist main machine is inverted, a protective cover cannot be installed for the hoist main machine to protect the hoist main machine, and the hoist main machine is easy to be polluted by cement and the like to cause chain clamping or chain breakage. In addition, the traditional normal hanging hoist mounting structure is shown in fig. 1, and comprises a hoist host and a hoist hook, wherein a chain of the hoist hook is not a closed circulating chain, in the process of lifting the climbing frame, as shown in fig. 2, the hoist host is fixed on a wall-attached lifting hanging seat, and each lifting layer needs to be manually detached and moved to the previous layer or the next layer for reinstallation, so that time and labor are wasted.
In view of the above, this embodiment provides an integrated automatic turn-around positive hanging block, as shown in fig. 3, comprising a block main unit 1, an endless chain 2, a tail-chain hook assembly 3, a top spring 4, a middle suspension point assembly 5, and a lower hook assembly 6; the endless chain 2 is wound around the hoist main machine 1, the tail chain lifting hook assembly 3, the middle lifting point assembly 5 and the lower lifting hook assembly 6 so that the climbing frame moves along with the rotation of the endless chain 2. The main machine 1 of the hoist is hung up, so that the main machine 1 of the hoist can be effectively protected, pollution is prevented, and the service life of the hoist is prolonged; the hoist motor 1 does not need to be disassembled and assembled in the lifting process, and the climbing frame can be lifted and lowered only by turning around the middle lifting point assembly 5 for disassembly and assembly, so that the manual work load is reduced.
In order to ensure that the forces of the hoist main body 1, the middle lifting point component 5 and the lower lifting hook component 6 are on the same straight line, the integrated automatic rotation normal hanging hoist is not deflected, in the embodiment, the hoist main body 1 and the tail chain lifting hook component 3 are separately arranged, the hoist main body 1 comprises a main body lifting hook 101 arranged on the hoist main body, and a main body driving wheel 102 connected with the hoist main body 1 and used for winding the annular chain 2, and the tail chain lifting hook component 3 comprises a tail chain lifting hook 301 and a tail chain sprocket 302 arranged on the tail chain lifting hook 301 and used for winding the annular chain 2.

In this embodiment, the loop chain 2 is wound in the manner shown in fig. 4: the first end of the endless chain 2 is fixed to the endless chain lower fixing point 501, then bypasses the lower hook right sprocket 601 downward, then bypasses the intermediate hook lower sprocket 503 upward, then bypasses the lower hook left sprocket 602 downward, then bypasses the main machine driving wheel 102 upward, then bypasses the intermediate hook upper sprocket 504 downward, then bypasses the tail chain sprocket 302 upward, and finally the other end of the endless chain 2 is fixed to the endless chain upper fixing point 502 downward. The lower lifting hook left chain wheel 602 and the lower lifting hook right chain wheel 601 on the lower lifting hook 603 are equivalent to two movable pulleys, 4 chains penetrating around the lower lifting hook left chain wheel 602 and the lower lifting hook right chain wheel 601 are all stress chains, and are equivalent to four stress chains, each stress chain averagely shares a load, three stress chains bypass the middle lifting point assembly 5 fixed with the wall body, the forces of the three stress chains are transmitted to the building through the middle lifting point assembly 5, the other stress chain is upwards connected with the main machine driving wheel 102, so that the bearing capacity of the main machine 1 of the hoist is about 1/4 of the whole load, the fatigue damage of the main machine 1 of the hoist can be obviously relieved, and the service life of the hoist can be prolonged. The other 3 chains at the upper part of the middle lifting point component 5 are not stressed and only bear the tensioning force of the top spring 4, so that the annular chain 2 can be ensured to be tensioned and not clamped.
In order to describe the use of the integrated automatic turnover hanging hoist in detail, this embodiment also provides an installation structure of the integrated automatic turnover hanging hoist, as shown in fig. 5, including a climbing frame body provided with an upper hanging point 7 and a lower hanging point 8, and the integrated automatic turnover hanging hoist, the hoist host 1 of the integrated automatic turnover hanging hoist is hung at the upper hanging point 7 through a host hook 101, the tail chain hook assembly 3 is hung at the upper hanging point 7 through a top spring 4, the lower hook assembly 6 is hung at the lower hanging point 8 through a lower hook 603, and the middle hanging point assembly 5 is detachably fixed with a wall body through an attached wall lifting seat 9.
The principle of lifting by adopting the installation structure of the embodiment is shown in fig. 6, the hoist host 1 is started, the host driving wheel 102 of the hoist host 1 drives the annular chain 2 to rotate, the climbing frame and the middle lifting point component 5 perform relative movement, and only the climbing frame moves due to the fact that the middle lifting point component 5 is fixed on a building, so that lifting of the climbing frame is realized. After the climbing frame ascends one layer, the middle lifting point component 5 is separated from the wall-attached lifting seat 9, the wall-attached lifting seat 9 is detached and moves upwards one layer to be fixed, then the electric hoist 1 is started, the middle lifting point component 5 also moves upwards one layer, and finally the middle lifting point component 5 and the wall-attached lifting seat 9 are connected well to prepare for the next lifting.
It should be noted that modifications and improvements can be made by those skilled in the art without departing from the inventive concept, and these are all within the scope of the present invention.
