The invention discloses a production technology of a waterproof and heat-insulated integrated board. The production technology comprises the following steps of: firstly, compositing an enhanced isolating material at one side of a waterproof roll; pre-heating the waterproof roll composited with the enhanced isolating material by a pre-heating device; compositing an heat-insulated material at one side of the waterproof roll composited with the enhanced isolating material after pre-heating; and finally, covering another pre-heated waterproof roll on the surface of the heat-insulated material. By providing the enhanced isolating material at one side of the waterproof roll, not only can the bonding strength between the enhanced isolating material and the waterproof roll be enhanced, but also the waterproof roll and the heat-insulated material can be effectively isolated; the condition that the waterproof roll is contacted with the heat-insulated material for a long time to cause chemical reaction can be avoided; a plasticizer inside the roll is prevented from migrating; the quality of the product is ensured; a procedure of pre-heating the waterproof roll is added before the waterproof roll and the heat-insulated material are composited; and the phenomenon that a waterproof layer and an insulating layer are stripped after the board is molded can be avoided, and the performance and quality of the board are further improved.

The invention relates to a device used to align, position and guide metal rolling element. Wherein, it comprise bank with guide plate with rolling element channel; the bank has cooling water open; the guide roller axle has oil let connected to oil ejector; the bank has at least a couple of crossed guide roller at 2aphla angle; two guide rollers with arc holes are inserted into the rolling element channel inclined, to form trapezium hole; when the rolling element is through said trapezium hole, the roller will align, clamp and correct the rolling element to vertically feed long axle into round hole or square hole. The invention has simple structure while it can reduce the impact of rolling element on guide roller and bearing, to prolong its service life.

The invention relates to a lifting device, in particular to a cross head pin lifting device applied to a reciprocating compressor. A lifting device body of the lifting device is of a concave shape. A lifting rope of lifting equipment is connected with the end of a first side rod of the lifting device body, and the end of a second side rod of the lifting device body is connected with a cross head pin. The second side rod is sleeved with a movable collision block. A first stopping ring and a second stopping ring are fixedly arranged on the second side rod and located at the front side and the rear side of the collision block separately. The cross head pin can collide with any stopping ring to move through the collision block. By the adoption of the cross head pin lifting device, the labor intensity of workers is relieved, safety is improved, and meanwhile quality accidents caused by human factors are reduced.
