Description

Technical Field

[0001] The utility model relates to the technical field of insulation pipes, in particular to a grinding device for the production of insulation pipes with an inner wall that can be ground. Background Technique

[0002] An insulation pipe is short for an adiabatic pipe. Insulation pipes are used for the transportation of liquids, gases and other media, and are used for the adiabatic engineering insulation of pipes in petroleum, chemical industry, aerospace, hot springs - military, central heating, central air conditioning, municipal engineering, etc. During the production process of insulation pipes, the inner wall needs to be ground. After retrieval, the Chinese patent with the publication number CN213225386U discloses a grinding device for insulation pipes. When grinding a pipe fitting, one end of the pipe fitting is inserted into the grinding machine body, and then the other end of the pipe fitting is placed between two arc-shaped clamping plates, so that the two arc-shaped clamping plates can fix and clamp the pipe fitting. Then, the grinding machine body is started, so that the pipe fitting is ground inside the grinding machine body. When the grinding machine body is grinding, it drives the pipe fitting to rotate and move. Clamping the pipe fitting by two arc-shaped clamping plates has poor stability and is prone to tilting during the grinding process, and thus the grinding effect of the insulation pipe is poor. Therefore, a grinding device for the production of insulation pipes with an inner wall that can be ground is designed, which is convenient for internally and externally clamping the insulation pipe through an internal grinding mechanism and an external rotation mechanism, without an additional clamping mechanism and improving the grinding stability at the same time.

The internal grinding mechanism and the external rotating mechanism are vertically arranged on the frame 1, and a bidirectional spacing adjustment mechanism for adjusting the distance between the internal grinding mechanism and the external rotating mechanism is arranged on the frame 1. The internal grinding mechanism includes a horizontally arranged grinding roller 3, and the external rotating mechanism includes a horizontally arranged driving roller 2. The grinding roller 3 and the driving roller 2 are vertically distributed. Both the internal grinding mechanism and the external rotating mechanism further include driving components, and the two driving components respectively drive the grinding roller 3 and the driving roller 2 to rotate. It further includes a heat-insulating pipe supporting mechanism, and the heat-insulating pipe supporting mechanism includes two supporting rollers 4 respectively arranged on both sides of the driving roller 2, and the two supporting rollers 4 can move up and down.

A driving motor 7 is fixedly installed on the support slide base 6. The driving motor 7 is drivingly connected to the driving roller 2 through a transmission assembly 8. When the driving motor 7 is started, through the transmission of the transmission assembly 8, the driving roller 2 is driven to rotate. The rotation of the driving roller 2 can drive the insulation pipe to rotate from the outside. The structure of the driving assembly for driving the grinding roller 3 is the same. The grinding roller 3 is rotatably connected to the support slide base 6, and the structure and starting method are the same. The rotation of the grinding roller 3 can grind the insulation pipe. Further, the transmission assembly 8 can adopt the transmission methods of sprocket chains, belt pulleys, or synchronous belts for transmission, and the sprocket chain transmission method is preferably adopted.

[0023] Specifically, the bidirectional spacing adjustment mechanism includes a bidirectional adjustment frame 9 fixedly installed on the frame 1. A bidirectional screw 10 is rotatably connected to the bidirectional adjustment frame 9. Two support slide bases 6 are symmetrically threadedly connected to both sides of the bidirectional screw 10 and are both in guiding sliding fit with the bidirectional adjustment frame 9. It also includes a longitudinal spacing adjustment motor 11 for driving the bidirectional screw 10 to rotate. The longitudinal spacing adjustment motor 11 is fixedly installed on the bidirectional adjustment frame 9. When the longitudinal spacing adjustment motor 11 is started, the output shaft of the longitudinal spacing adjustment motor 11 rotates clockwise or counterclockwise, which is convenient for driving the bidirectional screw 10 to rotate clockwise or counterclockwise, thereby driving the two support slide bases 6 to move towards the middle or towards both sides, and further driving the driving roller 2 and the grinding roller 3 to move towards the middle or towards both sides.

[0024] Specifically, it further includes a lifting mechanism adapted to the two supporting rollers 4. The lifting mechanism includes a lifting driving cylinder 15 fixedly installed on the frame 1.

The stabilizing mechanism includes a one-way adjustment frame 12 fixedly installed on the machine frame 1. A one-way screw rod 13 is rotatably connected to the one-way adjustment frame 12 through a lifting adjustment motor 14. A roller bracket 5 that is vertically guided and slidably matched with the one-way adjustment frame 12 is threadedly connected to the one-way screw rod 13. A feeding gap is provided between the two stabilizing mechanisms. Through the feeding gap, it is convenient to sleeved the heat preservation pipe on the grinding roller 3.
