The utility model discloses a dry tail gas heating vaporization sledge device which comprises a control box and a smoke outlet which are arranged on a heating vaporization sledge combustion chamber, and a heat dissipation screen frame is arranged at the upper end of the heating vaporization sledge combustion chamber. According to the skid device for heating and vaporizing the dry tail gas, by arranging a dismounting and washing assembly and pulling a pull ring upwards, an outer pressing plate is driven to move, meanwhile, a movable inner plate moves in a movable groove, a positioning spring is stretched, an elastic end is extruded, and after a clamping plate is taken out of a bayonet to be inserted, fixation of an upper positioning plate is relieved; the whole connecting outer frame can be in a movable state, the smoke exhaust port is moved outwards, the upper positioning plate is pulled out of a groove of the connecting outer frame, the inner circulation box is moved out of the smoke exhaust port and is taken away by a worker for cleaning operation, it is guaranteed that the inner face and the outer face can be kept clean, and meanwhile the situation that the inner face and the outer face are prone to being affected by dust accumulation is avoided; therefore, the convenience is improved.

This utility model provides a feeding compensation device for a fully automatic film coating machine, including a supporting base plate placed on an external lifting platform for supporting materials, a plurality of placement slots equally spaced on the supporting base plate, a plurality of support rods with one end set on the supporting base plate within each placement slot and the other end located outside the placement slot, and a counterweight block set on the other end of each support rod. The length of the support rod is greater than the length of the placement slot, and the support rod is fitted with the placement slot with a clearance. By subsequently increasing the lifting stroke of the lifting platform, the lifting frequency of the lifting platform is reduced, thereby reducing the energy consumption of the lifting platform due to frequent start-stop.

The invention discloses a direct-current speed reduction motor which comprises a motor body, a speed reduction assembly and a maintaining assembly, and the maintaining assembly comprises a maintaining frame, a deformation part and a maintaining part. During installation, pressure is applied to the two retaining pieces in the opposite directions, so that the deformation pieces are stressed to deform, the area of the compression area is reduced, the retaining pieces enter the sliding grooves, the positioning blocks on the speed reduction assembly are inserted into the compression area, and the fixing holes and the retaining pieces are kept to be matched for limiting. The direct-current gear motor is compact in structure, connection of the motor body and the speed reduction assembly is achieved through the maintaining assembly, and the speed reduction assembly can be assembled for use in use modes of different scenes, or the motor body can be independently used for use. Meanwhile, the speed reduction assembly can be installed or assembled without the cooperation of other special tools through the maintaining assembly, so that workers can conveniently, timely and rapidly disassemble and assemble the speed reduction assembly, and in addition, the trouble of carrying special disassembling and assembling tools is saved.

The utility model relates to the technical field of resistance welding, and discloses a multi-point resistance welding device which comprises a bottom plate, an adjusting welding device is arranged at the top of the bottom plate, and a mounting device is arranged at the top of the bottom plate. And the adjusting welding device comprises a welding positioning plate, a positioning sliding frame, a connecting block, a rectangular vertical block, a limiting sliding rod, a sliding block, a welding seat, an inner heating pipe placing ring piece and a placing plate, and the welding positioning plate is connected to the top of the bottom plate. According to the multi-point resistance welding device, the welding adjusting device is arranged, limiting can be conducted during sliding through a front positioning sliding frame and a rear positioning sliding frame, the transverse position can be adjusted, then longitudinal adjustment is needed, the top of a sliding block needs to be held during longitudinal adjustment, and then the sliding block is made to slide front and back in the mode of being attached to the surface of the sliding block; and the position of the upper welding assembly is adjusted to ensure that the upper welding assembly can smoothly and stably move to the position above the to-be-machined resistor piece, and machining treatment can be conducted.

The invention provides a guiding structure and a rolling mill guiding and guarding system, and relates to the technical field of guiding and guarding devices.The guiding structure comprises a main guiding block and an auxiliary guiding assembly, the main guiding block extends in the height direction and comprises a supporting part and a clamping part arranged on the supporting part in a protruding mode, and the supporting part is detachably connected with a rolling mill housing; the auxiliary guiding assembly comprises a plurality of auxiliary guiding blocks arranged in the height direction, the auxiliary guiding blocks are detachably connected with the supporting part and are opposite to the clamping part, and guiding grooves are formed between the auxiliary guiding blocks and the clamping part and used for guiding the guiding and guarding device. Guiding and supporting effects can be provided for the guiding and guarding device through the guiding structure, lateral displacement and vibration of the guiding and guarding device are prevented, and therefore accurate guiding and stable supporting of a steel plate are achieved through the guiding and guarding device. Moreover, after the auxiliary guide block is damaged, the damaged auxiliary guide block can be conveniently and timely disassembled, replaced and maintained, and the maintenance time is greatly shortened.
