Description

Technical Field

[0001] The utility model relates to the technical field of tower crane climbing, in particular to a tower crane inter-layer transverse ladder. Background Art

[0002] Tower crane, also known as tower crane, originated in Western Europe. It is a rotating crane with a boom mounted on the top of a tall tower. It has a large working space and is mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes tower body, boom and base, etc. The working mechanism has four parts: lifting, luffing, rotation and travel. The electrical system includes motors, controllers, distribution cabinets, connecting lines, signals and lighting devices, etc.

[0003] Tower crane is an important lifting device in building construction. In actual use, personnel are required to climb up to perform relevant operations. However, in actual use, due to the high floors, it is time-consuming and labor-intensive for personnel to climb. Therefore, personnel often take an elevator to the top of the floor, and then enter the interior of the tower crane through the top to climb down to reduce the climbing height. Traditional inter-layer horizontal ladders are often temporarily built with steel pipes, so they are less safe in actual use. At the same time, as the floors are higher, frequent construction is required, which cannot meet actual use needs.

[0004] In order to solve the above problems, we have made improvements and proposed a tower crane inter-layer horizontal ladder. Utility Model Content

[0028] The telescopic device 3 includes a connecting ring 301 arranged on the outside of the circular mounting block 1, a bottom plate 302 fixedly installed on the right side of the connecting ring 301, and a telescopic plate 307 arranged on the top of the bottom plate 302. A connecting groove 310 is opened inside the circular mounting block 1, and the connecting ring 301 is inserted inside the connecting groove 310.

[0029] A first side guard plate 311 is fixedly installed on both sides of the top of the bottom plate 302, and a second side guard plate 312 is fixedly installed on both sides of the top of the telescopic plate 307. The cooperation between the first side guard plate 311 and the second side guard plate 312 is used to protect personnel and increase the stability of personnel when going up and down. A receiving groove 305 is provided inside the first side guard plate 311, and the second side guard plate 312 is inserted inside the receiving groove 305. The setting of the receiving groove 305 facilitates the storage of the second side guard plate 312 when the telescopic plate 307 is adjusted.

[0030] A thread groove is provided inside the telescopic plate 307, and the internal thread of the thread groove is connected to the second bolt 306. The bottom of the second bolt 306 contacts the top of the bottom plate 302. The second bolt 306 is installed by setting the thread groove. The bottom plate 302 is squeezed by the setting of the second bolt 306. Under the reaction force of the thread, the telescopic plate 307 is squeezed and fixed to increase the stability of the telescopic plate 307.

[0031] Two slide grooves 303 are provided on the top of the bottom plate 302, and a slider 308 is slidably connected inside the slide grooves 303. The top of the slider 308 is fixedly connected to the bottom of the telescopic plate 307. The cooperation between the slide grooves 303 and the slider 308 realizes the connection of the telescopic plate 307 relative to the bottom plate 302, and at the same time, the stability between the bottom plate 302 and the telescopic plate 307 is increased. Two accommodating grooves 304 are provided on the right side of the bottom plate 302, and two push rods 309 are threadedly connected to the bottom of the telescopic plate 307. The push rods 309 are inserted into the inside of the accommodating grooves 304.

The setting of the push rods 309 realizes the support of the right side of the telescopic plate 307 relative to the building to increase the stability of the right side of the telescopic plate 307.

[0032] See also Figure 1 , 4 5. A tower crane inter-layer transverse ladder, wherein the fixed guide device 2 comprises two transverse fixing rods 201 arranged on the top of the circular mounting block 1 and four guide rollers 203 arranged on the inner side of the rectangular through cavity 4. A triangular groove 205 is provided inside the guide roller 203. The circular mounting block 1 is fixed relative to the tower crane frame by setting the transverse fixing rods 201 to increase the stability of the circular mounting block 1. The outer frame of the tower crane is limited and squeezed by the cooperation between the guide rollers 203 and the triangular grooves 205 to facilitate the lifting and sliding of the circular mounting block 1.

[0033] Mounting frames 204 are fixedly installed on both sides of the guide roller 203, and one side of the mounting frame 204 is fixedly installed inside the rectangular through cavity 4. First bolts 202 are inserted on both sides of the transverse fixing rod 201. The bottom of the first bolt 202 penetrates into the interior of the circular mounting block 1 and is rotatably connected to the circular mounting block 1 through a thread. The connection of the transverse fixing rod 201 relative to the circular mounting block 1 is achieved through the setting of the first bolt 202, and at the same time, the disassembly of the transverse fixing rod 201 is convenient for the overall lifting and lowering movement, and then real-time adjustment according to the increase in the floor.

[0034] The working principle of the utility model is as follows: in the early stage of tower crane installation, after the base is installed, the whole is lifted and sleeved on the outer side of the tower crane support frame, so that the guide roller 203 and the triangular groove 205 are in contact with the outer side of the tower crane outer frame, so as to limit the circular installation block 1. When it is actually used and needs to be built, the whole is lifted up by the tower crane, and after the ascent is completed, the connecting ring 301 and the connecting groove 310 are rotated to make the bottom plate 302 move to the side close to the floor. After the rotation is completed, the telescopic plate 30 is moved according to the distance between the tower crane and the floor. 7 is pulled toward the inside of the floor so that the telescopic plate 307 extends to the top of the floor. The telescopic plate 307 is fixed by tightening the second bolt 306 and squeezing the bottom plate 302. At the same time, the top rod 309 is rotated to contact the floor and thus support the right side of the telescopic plate 307. After the installation is completed, the transverse fixing rod 201 is inserted into the inside of the tower crane and connected to the circular mounting block 1 through the first bolt 202. After the connection is completed, the personnel can go up and down the tower crane through the bottom plate 302 and the top of the telescopic plate 307.
