The utility model discloses a kind of adjustable jacking devices for friction type electrostatic impurity removal machine, it is related to jacking device technical field, including fixed frame, the outside of the fixed frame is equipped with buffer spring assembly, the outside of the buffer spring assembly is equipped with bed shaking assembly, the outer surface of the fixed frame is detachably connected with support frame, the outside of the support frame is equipped with worm screw lifting machine assembly, by the cooperation between worm screw lifting machine assembly and hanger ring etc. When it is necessary to control the movement of the roller frame, rotate the worm screw lifting machine assembly. At this time, the hanger ring can be moved by the first connector, and the roller frame can be moved by the hanger ring. Since the position of the screw rod is relatively low, the space at the top of the device is less affected, and the space at the top is more open. This realizes the function of jacking the device at a lower position, which is beneficial to reduce the occupied space at the top of the device and facilitate the extension of the function.

The invention relates to the technical field of thermal power equipment, and discloses a peripheral sparse column steel frame of a washing and absorbing two-tower-in-one structure, which comprises a steel column inner frame, a steel column outer frame and a horizontal support structure: the steel column outer frame and the steel column inner frame are both of a square frame structure, and the horizontal section is rectangular; the central tower is arranged in the peripheral sparse column steel frame; the steel column inner frame is arranged on the outer side of the center tower in a surrounding mode, and the steel column outer frame is arranged on the outer side of the steel column inner frame in a surrounding mode. The steel column inner frame and the steel column outer frame are connected and fixed through a horizontal supporting structure. A plurality of rows of horizontal platforms and a plurality of columns of steel latticed columns are arranged on the peripheral sparse column steel frame, and a large cubic space is formed between the two rows of horizontal platforms and the two columns of steel latticed columns; and each layer of filler in the central tower and the pipelines outside the tower transmit loads to the peripheral sparse column steel frame. According to the invention, the occupied area is reduced, the height and the capacity of the tower are increased and the like while the water washing tower and the absorption tower are integrally arranged, the space is relatively wide, and the possibility of collision with a pipeline can be reduced.

The utility model discloses a target material transfer device for semiconductor chip manufacturing, including transfer flat -bed truck, and the receiving subassembly of transfer flat -bed truck upper end face is provided with, and the sheltering subassembly of receiving subassembly outside is provided with, through setting up the receiving cavity on the receiving box upper end face, the target material body is placed in the receiving box and is transferred for the convenience of user, and because a plurality of receiving boxes are placed respectively on the front and back two sides of first support plate and second support plate upper end face, the space around is also relatively open, also is convenient for user to carry out the convenient taking of receiving box and target material body and put, through the sheltering of surrounding board placing on transfer flat -bed truck, can make the sheltering of surrounding board to the target material body in receiving box and shield protection, avoid the target material body in being transferred process direct exposure and receive knock, through setting up first weight reduction through cavity and second weight reduction through cavity, can further reduce the dead weight of sheltering surrounding board to make the sheltering surrounding board in being taken more portable.

The utility model relates to a ram fixing piece, tent support structure and tent, including the first connecting part and the second connecting part that are fixed and connected into one piece, the first connecting part is provided with a first plug hole, the second connecting part is provided with a second plug hole, the first plug hole and the second plug hole form an included angle of 145-170 degrees; the included angle ranging from 145 degrees to 170 degrees is formed between the first inserting hole and the second inserting hole, so that the ram arranged in the first inserting hole can be lifted upwards by 10 degrees to 25 degrees relative to the main body framework, the ram can be lifted upwards to be in an approximately horizontal state, the situation that an eave occupies the space in the vertical direction of the door is avoided, and the influence on a user going in and out of the door is avoided.

The utility model relates to a kind of cleaning device of roller bit rig drill rod, it is characterized in that, including base, sewage tank, roller bit rig drill rod support mechanism, cleaning mechanism and sliding mechanism;Sewage tank is placed on base, roller bit rig drill rod support mechanism is made of two portal frames and the support wheel group of setting two portal frames upper portion, respectively interval span is set in the both sides of the sewage tank, cleaning mechanism and sliding mechanism are respectively set on base, sewage tank and roller bit rig drill rod support mechanism upper portion, and with base sliding connection.The utility model is by setting open sewage tank, after arc cover is blocked to splashing sewage, so that sewage smoothly enters the inside of sewage tank, by the sewage tank that is set obliquely and inner wall is handled by anti-sticking coating coating, can be guided to discharge the sewage containing soil smoothly, subsequent processing is facilitated to sewage.

This invention relates to a welding apparatus and method for a plate-type radiator, comprising a fixing frame and a lifting mechanism; a flipping mechanism is disposed between two lifting mechanisms; the flipping mechanism includes a clamping and positioning unit and a rotating positioning unit; the flipping mechanism includes a rotating cylinder; the clamping and positioning unit can extend and retract relative to the rotating cylinder to pre-position or clamp and position the radiator fins; the rotating positioning unit can rotate circumferentially relative to the rotating cylinder, and the rotating positioning unit includes clamping heads that clamp the oil collection pipe from the left and right, so that while the clamping and positioning unit clamps and positions the radiator fins, the radiator fins are also clamped through the oil collection pipe; the welding assembly includes a position-adjustable welding head; the welding head can be aligned with the contact position between the radiator fins and the oil collection pipe in the optimal posture for welding, thereby improving welding quality and reducing operation difficulty; the radiator fins are simultaneously subjected to direct clamping from the clamping and positioning unit and lateral clamping from the oil collection pipe, forming dual positioning and improving welding stability.
