The invention relates to a safe replacement device for a soil pressure sensor. The safe replacement device comprises a mounting hole formed in a shield tunneling machine shell, an inserting plate, andthe soil pressure sensor; the mounting hole communicates with an excavation cabin located in the front portion of the shield tunneling machine shell and the interior of the shield tunneling machine shell; the inserting plate is mounted in the shield tunneling machine shell and arranged at the mounting hole, the inserting plate can slide on the shield tunneling machine shell, and the mounting plate is plugged through the inserting plate by sliding the inserting plate; and the soil pressure sensor is arranged in the mounting hole in an inserted mode and detachably connected with the inserting plate. The safe replacement device has the beneficial effects that the slidable inserting plate is adopted, thus before the base and the soil pressure sensor are jointly taken down from the inserting plate, the mounting hole formed in the shield tunneling machine shell and used for accommodating the soil pressure sensor can be plugged only by sliding the inserting plate, the situation that underground mud water in the excavation cabin flows back into a shield tunneling machine is avoided, thus when the soil pressure sensor is dismounted and mounted during maintenance, the time and labor are saved, and the risk is extremely small.

The invention relates to the field of building decoration, and provides a wall surface fast leveling hanging installation structure which is simple in structure, convenient to construct, and labor-saving and time-saving to install and dismount, and integrated with positioning and leveling. Technical problems existing in the prior art that the wall surface leveling and hanging installation construction is troublesome, the construction period is long, the construction difficulty is large, and the construction is time-consuming and labor-consuming and the like are solved. The wall surface fast leveling hanging installation structure comprises a decoration panel fixed on the wall surface, the wall surface corresponding to the decoration panel is provided with an L-shaped hanging member, the vertical surface of the L-shaped hanging member is flatly pasted and fixed on the wall surface, the transverse surface of the L-shaped hanging member extends outwards, the outer end face of the vertical surface extends upwards and outwards to form an upper inclined leading-in clamping plate, the outer end face of the transverse surface extends downwards and inwards to form a lower inclined elastic clamping plate, the decoration panel is correspondingly provided with a hanging member mounting groove, the upper inclined leading-in clamping plate is upwards matched with and in clamp connection with a corresponding inclined groove in the upper end of the hanging member mounting groove, and the lower inclined elastic clamping plate is in clamp connection with the edge of the opening of the hanging member mounting groove elastically.

The invention discloses a supporting device for an ultra-low temperature thermal decoupling turbine rotor, comprising a bearing housing support body (2), a top fixing component (5), a bottom fixing component (6), a clamping component (7) and a thermal insulation Components; the thermal insulation component is set in the casing (3); the bearing box support body is fixedly installed in the casing through the top fixing component and the bottom fixing component to limit its circumferential, horizontal, vertical and axial displacement; both sides of the casing There is a support part (31), and the support contact surface (310) of the support part is located in the same horizontal plane as the assembly contact surface of the bottom fixing component and the bearing box support body; a pair of clamping components are arranged in the casing and clamped symmetrically On both sides of the bearing box support body and limit its axial displacement. The invention can avoid the problem of thermal stress generated when the connecting parts of the compressor are operated in an ultra-low temperature environment, and can also ensure that the elevation of the shaft system of the compressor remains unchanged in different temperature fields.

The invention provides an electric heater. The electric heater comprises a shell body and a control panel, wherein a supporting structure is arranged at the top of the shell body; the control panel ismounted at the top of the shell body; buckle structures which are matched with each other are arranged on the shell body and the control panel, thus the shell body is connected with the control panel, and the supporting structure is supported and located on the lower part of the control panel to support the control panel. According to the technical scheme, the problem of inconvenient operation ofa control panel of an electric heater in the prior art is effectively solved.

The invention discloses a quick mounting and dismounting structure for filter cores of a filter. The quick mounting and dismounting structure includes an upper tray, a support cylinder and a lower tray which are connected in sequence, and also includes a plurality of filter cores fixing between the upper tray and the lower tray through filter core mounting holes arranged on the upper tray and the lower tray; the filter core mounting holes of the upper tray are each internally provided with an annular groove, and each annular groove is internally provided with an earless elastic hole baffle ring. The quick mounting and dismounting structure is low in cost, and adopts simple tools during dismounting; hand pushing is performed during mounting, no dedicated tools are required, bolts are not required to be mounted or dismounted, and mounting and dismounting save time and labor and are convenient and fast; the diameter of the earless elastic hole baffle rings is larger than the diameter of the filter core mounting holes, so that the baffle rings do not fall into the interior of the filter; two faces of each filter core mounting hole are each processed with a 60-degree chamfer, so that pulling-out and mounting-in of the filter cores are smooth, the work efficiency is greatly improved, and the labor intensity is reduced; the working surface of the upper tray is flat and smooth, the friction force is small, and reliable, smooth and steady operation of the automatic backwashing filter is ensured.

A parking device of a motorcycle include a core shaft which penetrates a frame of the motorcycle; a parking unit which is pivoted to the core shaft and can rotation with the core shaft as an axial center; and a limiting unit which is used for limiting rotation of the core shaft; the limiting unit includes a first limiting mechanism formed on the frame, and a second limiting mechanism which is formed on the core shaft in a manner that the second limiting mechanism is clamped with the first limiting mechanism. The first limiting mechanism and the second limiting mechanism which are mutually clamped and formed on the frame can limit rotation of the core shaft with respective to the motorcycle; and the parking device is easy to demount, and time and effort can be saved while the parking device is demounted.

An automatic loading stretcher system arranged in a carriage. The stretcher system comprises a stretcher assembly (11, 12), a link mechanism and a control system. The link mechanism swings to enable the stretcher assembly (11, 12) to rotate, lift, extend out of or retract back to the carriage. The stretcher assembly (11, 12) comprises a stretcher platform (13) and a guide table (49). Stretchers (14) are detachably installed on the guide table (49). The guide table (49) can move forward and backward on the stretcher platform (11, 12). The control system comprises a programmable controller (77), an electromagnetic valve (75) and proximity switches (71, 72, 73, 74). The control system controls a cylinder (24) to drive the link mechanism to swing and controls a motor (42) to drive the guide table (49) to move forward and backward, and a plurality of automatic loading stretcher systems can be installed in the carriage. The automatic loading stretcher system has the advantages that the guide table can be automatically placed outside the carriage so that the wounded can be conveniently and safely loaded and unloaded; a stretcher fixer can fix the stretchers on the guide table conveniently; and the efficiency of transporting the wounds is improved due to the plurality of stretcher systems.
