Description

Technical Field

[0001] The utility model relates to the technical field of boiler hanging devices, in particular to a combined tool for installing boiler suspension rods. Background Art

[0002] In the installation of conventional boilers, the combination of hanging devices is extremely common. For example, a suspension rod combination with a turnbuckle between two suspension rods. In the past combination method, the turnbuckle was first connected to one of the suspension rods as a whole, and then the second suspension rod was connected to the turnbuckle. At this time, due to the long length, large diameter and heavy weight of the suspension rod, when aligning the threads, the second suspension rod was often rotated by a pipe wrench. By using this method for combination, due to the uneven angle and force of each use of the pipe wrench, the suspension rod may be deflected and the thread engagement is incorrect, which will cause the suspension rod and the turnbuckle to be stuck and unable to move. More seriously, the threads may be damaged, resulting in the turnbuckle being unusable.

[0003] The Chinese utility model patent with the publication number of CN207434838U discloses a device for quickly combining boiler suspension rods.

[0019] The following further describes this utility model in conjunction with the accompanying drawings and embodiments:

[0020] As Figures 1 to 3 shown, a combined tool for installing boiler suspension rods includes a U-shaped base 1, a fixed pin 2, a first rolling bearing 3, a horizontal oblong hole 4, an adjusting pin 5, a fastening nut 6, a second rolling bearing 7, and an auxiliary fastening nut 8.

[0021] A fixed pin 2 is installed between the two side plates of the U-shaped base 1. A first rolling bearing 3 is provided on the fixed pin 2. Horizontal oblong holes 4 are symmetrically formed on the two side plates of the U-shaped base 1. An adjusting pin 5 is inserted through the two horizontal oblong holes 4. The adjusting pin 5 and the fixed pin 2 are on the same horizontal line. Fastening nuts 6 are screwed on the ends of the adjusting pin 5 protruding from the two side plates of the U-shaped base 1. A second rolling bearing 7 is provided on the adjusting pin 5.

[0022] The U-shaped base 1 can be made of channel steel.

[0023] The fixed pin 2 and the adjusting pin 5 can be made of round steel.

[0024] The working principle of this utility model is as follows:

[0025] First, fix the first suspension rod 9 with a turnbuckle 11, and then place the second suspension rod 10 to be installed on this utility model's tool, one at each of the bottom ends, and adjust the position to ensure that the first suspension rod 9 and the second suspension rod 10 are concentrically arranged; then wind the hemp rope 12 around the second suspension rod 10 as Figure 4 shown, and note that the winding direction should be the same as the installation rotation direction of the second suspension rod 10 to be installed; finally, pull the hemp rope 12 through the hoisting mechanical component 13 to rotate the second suspension rod 10 to be installed to complete the installation work. Leave enough length for the hemp rope 12 at the free end to ensure that the installation is completed in one pass.

[0026] The first rolling bearing 3 and the second rolling bearing 7 in the tool can support the second suspension rod 10 to avoid deviation during the installation process, and the rolling form of the first rolling bearing 3 and the second rolling bearing 7 is used to reduce the external force required for the installation of the second suspension rod 10.

[0027] The second rolling bearing 7 can adjust its position as needed, thereby changing the distance between the first rolling bearing 3 and the second rolling bearing 7, and can be applicable to the installation of boom poles of various specifications.

[0028] The first rolling bearing 3 and the second rolling bearing 7 are arranged with a front-back offset, which can avoid mutual interference inside the first rolling bearing 3 and the second rolling bearing 7, and enables a wider adjustment range.

[0029] The inner ring of the first rolling bearing 3 is fixedly welded to the outer wall of the fixed pin shaft 2, and the inner ring of the second rolling bearing 7 is fixedly welded to the outer wall of the adjusting pin shaft 5.

[0030] Auxiliary fastening nuts 8 are screwed tightly on the inner sides of the side plates of the U-shaped base 1 at both ends of the adjusting pin shaft 5. The auxiliary fastening nuts 8 can fasten the adjusting pin shaft 5 more firmly and avoid dislocation movement.

[0031] External threads are provided at both ends of the outer wall of the adjusting pin shaft 5, and the adjusting pin shaft 5 is screwed and installed with fastening nuts 6 and auxiliary fastening nuts 8 through the external threads.

[0032] Anti-slip pads are provided at the bottom of the U-shaped base 1, which can improve the anti-slip ability.

[0033] Handles are provided on the outer sides of the two side plates of the U-shaped base 1, which are convenient for moving and holding.
