Description

Technical Field

[0001] The utility model relates to the technical field of support frames, in particular to a support frame for producing electric heating radiation tubes. Background Art

[0002] The electric heating radiant tube is a device that converts electrical energy into thermal energy to heat the material to be heated. The electric heating element is enclosed in a protective sleeve. After power is turned on for heating, the sleeve indirectly radiates heat to the furnace lining and the heated workpiece. The heating of the electric heating radiant tube is suitable for furnaces with protective atmosphere and corrosive atmosphere, such as continuous furnaces, drum furnaces, pit furnaces, etc.

[0003] When processing electric heating radiation tubes, the processing process requires many steps. After each step of the process is completed, the electric heating radiation tube is generally placed on a support frame to store the electric heating radiation tube. After this step of the process is completed, the support frame can be directly picked up by a forklift, and then the support frame and the electric heating radiation tube are sent to the next processing site. The width of the common support frame cannot be adjusted, and the length of the produced electric heating radiation tubes is long or short, so different support frames need to be used according to the length of the electric heating radiation tube.

[0004] To this end, we propose a support frame for producing electric heating radiant tubes to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problems existing in the prior art and to propose a support frame for producing electric heating radiant tubes.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The lockhole that is formed on the upper of the two said the upper and lower ends of the lifting link is formed on the second lateral side of the lifting link, and the lockhole that is formed on the upper and lower ends of the lifting link is formed on the second lateral side of the lifting link.

[0008] Preferably, the cross-connecting rod includes two mutually crossing long rods and a rotating shaft, and the rotating shaft is arranged to pass through the two long rods, and the rotating shaft is rotatably connected to the long rods.

[0009] Preferably, a cavity is opened inside the frame, and one end of the second threaded rod passes through the frame and extends to the inside of the cavity. One end of the second threaded rod located inside the cavity is fixedly connected to the first gear, the side wall of the first gear is engaged with the second gear, and the inner wall of the second gear is fixedly connected to the telescopic connecting rod.

[0010] Preferably, the telescopic connecting rod includes a first connecting rod and a second connecting rod, the inner wall of the second connecting rod is slidably sleeved on the outer wall of the first connecting rod, one end of the first connecting rod is rotatably connected to one of the frames, and the second connecting rod is rotatably connected to the other frame, and one end of the second connecting rod passes through the cavity and extends to the outside of the cavity.

[0011] Preferably, a hexagonal hole is formed at one end of the second connecting rod located outside the cavity.

[0012] Preferably, a bolt is threadedly connected to the outer wall of the second sliding tube, and one end of the bolt passes through the second sliding tube and abuts against the first sliding tube.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The utility model provides a first threaded rod and a second threaded rod for use in conjunction with each other. When the first threaded rod and the second threaded rod are rotated, the cross-connecting rod can push the two frames apart, and the distance between the two frames can be changed, so as to change the length of the electric heating radiation tubes that the two frames can support and set. Therefore, when producing electric heating radiation tubes, the support frame can be used regardless of whether long electric heating radiation tubes or short electric heating radiation tubes are produced. By providing a telescopic connecting rod, a first gear and a second gear for use in conjunction with each other, when in use, the telescopic connecting rod can be rotated to pass through the second gear and the first gear, thereby driving the two first threaded rods and the second threaded rods to rotate at the same time, thereby facilitating adjustment when adjusting the distance between the two frames.
