Description

Technical Field

[0001] The utility model relates to the technical field of installation mechanisms, in particular to an auxiliary device for installing a chimney. Background Art

[0002] The inner tube of a double-tube chimney needs to be inserted into the outer tube in the factory. Because the gap between the inner tube and the outer tube is small, and double-tube chimneys are generally equipped with an insulation layer, it is labor-intensive and unsafe to use a crane or workers to pull and drag the large inner tube into place, which will damage the paint inside the outer tube, damage the insulation layer of the inner tube, and cause deformation of the internal components. At this time, an auxiliary tool needs to be set up to allow the inner tube to slide smoothly into the outer tube.

[0003] After searching, the Chinese patent application number 202222081858.8 discloses a chimney inner tube installation auxiliary trolley; it relates to the technical field of installation mechanism, including: an outer tube flange is fixedly installed at the bottom of the outer tube; an inner tube is movably installed inside the outer tube; an inner tube flange is fixedly installed at the bottom of the inner tube; an auxiliary trolley is movably installed between the outer tube and the inner tube; the beneficial effect is; the chimney inner tube installation auxiliary trolley can place the inner tube flange on the bearing, and then limit the inner tube flange through the limiting groove, so that the inner tube flange is stuck in the limiting groove to prevent the inner tube flange from detaching; then the roller fits with the inner wall of the outer tube, and then the inner tube is lifted and slowly pushed forward by a crane, so that the roller rotates on the inner wall of the outer tube, so that the inner tube slides smoothly into the specified position inside the outer tube; thereby preventing the inner tube and the outer tube from being scratched and collided, causing damage to the inner tube and the outer tube. The above patent has the following deficiencies: the inner tank fixing method of the device is less versatile, and the pulley block cannot be adjusted, resulting in weak gripping force. Therefore, an auxiliary device for chimney installation is urgently needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an auxiliary device for chimney installation in view of the above problems.

[0011] Beneficial effects of the utility model:

[0012] 1. A motor is set to drive the rotating shaft at the center of the bottom plate, which further drives the turntable to rotate. A rotating rod slidably connected to the slide groove is set at one end of the clamping assembly, and a second slider slidably installed on the slide rail is set in the middle of the clamping assembly. Therefore, the rotation of the turntable drives the front and rear extension of the clamping assembly. A clamp connected to a spring is set at the end of the clamping assembly. When the turntable rotates and the clamping assembly extends, the clamp contacts the inner wall of the double-layer chimney liner. Because the clamp is slidably connected, when the clamping assembly continues to extend, the clamp will move backward. At this time, the spring will give the clamp a forward force to clamp the double-layer chimney liner, which solves the problem of poor versatility of the liner fixing method in the prior art;

[0013] 2. By setting an adjustment shaft, adjusting the angle between the first connecting rod and the second connecting rod and fixing it, the moving wheel set at the end of the moving component can form an angle with the inner wall of the grasping when following the extension and retraction of the moving component, thereby increasing the adsorption force. In addition, the mobile component can be extended and retracted to further enhance the applicability of the device, solving the problem in the prior art that the pulley group cannot be adjusted, resulting in weak grasping force.
