The protective shell is mounted and dismounted, so that the working time is shortened, the cost is saved, and a worker can conveniently maintain the protective shell.

The utility model discloses a saddle-shaped pipeline welding assembly which comprises a pipeline body, a welding seam is formed in the upper portion of the pipeline body, a main pipeline positioning sleeve is arranged on the outer side of the upper portion of the pipeline body, a fixing sleeve is fixedly connected to the top of the main pipeline positioning sleeve, and a pipeline connecting piece is arranged in the fixing sleeve. The end, away from the pipeline body, of the pipeline connecting piece is a round pipe, and the end, close to the pipeline body, of the pipeline connecting piece is a saddle-shaped skirt edge with the bottom shape corresponding to a weld joint. The pipeline connecting piece is provided with the saddle-shaped skirt edge which is in tangent transition with the round pipe, so that saddle-shaped edges and corners can be prevented from being formed at the pipeline connecting position, impact and kick flow caused when the pipeline connecting piece is used in a high-pressure and high-speed fluid environment are prevented, and the practicability of the device is enhanced.

The utility model belongs to the technical field of energy storage cabinets, and relates to an external antenna waterproof device for an energy storage cabinet, which comprises an energy storage cabinet, an antenna mounting cavity and a sealing plate, a wiring window is arranged on the side surface of the antenna mounting cavity, and a first wiring hole is arranged on the top surface of the antenna mounting cavity; a second wiring hole is formed in the sealing plate; the antenna mounting cavity passes through a mounting window formed in the side wall of the energy storage cabinet and then is fixedly connected with the inner side surface of the sealing plate, and the wiring window directly faces the second wiring hole; a cable of the external antenna sequentially passes through the second wiring hole, the wiring window and the first wiring hole from outside to inside and then is communicated with the interior of the energy storage cabinet. According to the utility model, the antenna mounting cavity is embedded in the energy storage cabinet, the cable of the antenna is introduced into the energy storage cabinet from outside to inside through the mounting window, and the routing path of the cable of the antenna is provided with an upturning slope and a slope which is high inside and low outside, so that external seepage water cannot enter the energy storage cabinet; therefore, the waterproof device is good in waterproof effect, firm, durable, free of water accumulation and high in protection level.

The utility model discloses a die device suitable for main shaft drilling, and mainly relates to the field of flange machining. Comprising a second annular seat, a first annular seat and an annular template which are coaxially connected in sequence, the end face of the side, away from the first annular seat, of the annular template is an annular matching end face, the outer diameter of the annular template is smaller than that of a flange workpiece, and the inner diameter of the annular template is larger than that of the flange workpiece. Two positioning columns matched with flange bolt holes are arranged on the edge of the matching end face, the two positioning columns are distributed at an angle of 90 degrees or 180 degrees relative to the circumferential face of the annular template, and the tail ends of the positioning columns are matched with fasteners for fixing a flange workpiece on the annular template. The tool has the advantages that outer circle machining and main hole machining are completed through one-time clamping, so that the coaxiality of the outer circle machining and the main hole machining is guaranteed, and the requirement for high machining precision is met.

The utility model discloses a trolley support suitable for variable cross section tunnel relates to trolley support technical field, including portal main part, telescopic spare is set up on portal main part, and it includes: the outer tube is axially horizontal and is arranged at the top of portal main part, and both ends are connected with outside, the threaded rod is coaxial and is arranged in the outer tube, and the annular gap is left between the outer wall of threaded rod and the inner wall of outer tube, the threaded cylinder is nested in the annular gap, and its inner wall is in threaded engagement with threaded rod. The utility model with the axial movement of threaded cylinder relative to outer tube in telescopic spare, can accurate regulation trolley support node's geometric size. Since the outer tube and threaded cylinder initial state both ends are flush, and the length is same, through rotating knob, can make telescopic output end's length of protruding according to actual demand change, thereby let same trolley support can match different size's tunnel section, need not for each kind of section alone custom-made trolley support, has greatly promoted the versatility of equipment.
