The setting of the self-locking universal wheels 120 facilitates the movement of the butt joint device.

[0027] The spacing adjustment mechanism 150 is installed on the frame 140. The setting of the spacing adjustment mechanism 150 enables the two arc plates 161 to move towards or away from each other. The spacing adjustment mechanism 150 includes a double-headed threaded rod 151, a guide rod 152, a first motor 153, and a support block 154. One end of the double-headed threaded rod 151 is rotatably arranged on the frame 140. The guide rod 152 and the first motor 153 are both fixed on the frame 140. The support block 154 is threadedly sleeved on the double-headed threaded rod 151, and the support block 154 is also slidably sleeved on the guide rod 152. There are two support blocks 154.

[0028] The clamping mechanism 160 is installed on the spacing adjustment mechanism 150. The setting of the clamping mechanism 160 realizes the clamping and fixing of the heat preservation pipeline. The clamping mechanism 160 includes an arc-shaped plate 161, an L-shaped plate 162, a second hydraulic cylinder 163 and an abutting seat 164. The arc-shaped plate 161 is fixed on the upper surface of the support block 154. The L-shaped plate 162 is fixed on the upper surface of the arc-shaped plate 161. The second hydraulic cylinder 163 is fixed on the L-shaped plate 162. The lower end of the piston rod of the second hydraulic cylinder 163 is fixed on the upper surface of the abutting seat 164. It also includes an anti-slip pad 165. The anti-slip pad 165 is fixed on the lower surface of the abutting seat 164. The setting of the anti-slip pad 165 increases the friction of the abutting seat 164;

[0030] Specifically, the working principle of this insulating pipe butt joint device is as follows: When in use, the insulating pipe is placed within the arc-shaped plate 161 by means of a lifting device. The second hydraulic cylinder 163 operates to drive the abutting seat 164 to move downward. The abutting seat 164 clamps and fixes the insulating pipe.

The two support blocks 154 move towards or away from each other under the combined action of the double-headed threaded rod 151 and the guide rod 152. By controlling the rotation direction of the output shaft of the first motor 153, the two insulating pipes are brought closer to each other. The first hydraulic cylinder 130 operates, and the telescopic movement of the piston rod of the first hydraulic cylinder 130 drives the insulating pipe to move upward or downward, so that the center line of the insulating pipe coincides with the center line of the circular slider 172. The cutting machine is installed on the welding robot 176. The second motor 173 operates, and the rotation of the output shaft of the second motor 173 drives the first gear 174 to rotate, that is, drives the second gear 175 to rotate, realizing the rotation of the circular slider 172 and the welding robot 176. The welding robot 176 and the cutting machine cooperate to realize the opening of the bevel of the insulating pipe. After the opening is completed, the first motor 153 operates again to align the two insulating pipes together. Then the cutting machine is removed. Under the combined action of the second motor 173 and the welding robot 176, the welding of the bevel is realized. This insulating pipe butt joint device does not require the use of a lifting device to move the insulating pipe back and forth, that is, the bevel opening and bevel welding of the insulating pipe are carried out on the same workbench, simplifying the steps and saving time. In addition, the automatic welding of the bevel is realized by using the first motor 153, the second motor 173 and the welding robot 176, saving manpower and having a high efficiency, bringing a better use experience to the user.

[0031] It should be noted that the specific model specifications of the first hydraulic cylinder 130, the first motor 153, the second hydraulic cylinder 163, the second motor 173 and the welding robot 176 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.
