The invention relates to the technical field of rail construction, in particular to a four-wheel small platform lorry for pre-assembled turnout slippage and a construction method. The four-wheel smallplatform lorry comprises a frame body and a pre-assembled turnout clamp, wherein the frame body is provided with oppositely arranged long edge sides and oppositely arranged short edge sides, at leasttwo pairs of wheel mounting plates are arranged downwards on each short edge side, a wheel shaft is connected between each pair of wheel mounting plates, the wheel shafts are connected to rail-mounted wheels, trapezoidal sections are arranged at the lower ends of the wheel mounting plates, the upper bottoms of the trapezoidal sections are positioned at the bottommost ends, clamping grooves are upwards formed in the middle of the bottom ends of the trapezoidal sections, and an arc-shaped end part is arranged at the upper end of each clamping groove. Compared with the prior art, the combined structure is simple, feasible and easy to assemble and disassemble, the size of the four-wheel small platform lorry can be small enough due to the structure so that the combined structure can be arranged at a gap between two sleepers under a pre-assembled turnout steel rail, the pre-assembled turnout can integrally slip to a designed position without adjusting the sleepers, and the sleeper spacing does not need to be adjusted.

The invention discloses a usage method of a trailer assembling system. The usage method comprises the steps of self adjustment of guide rail separation distances, self movement of supporting parts, erection of taking-off assembly parts, erection of frame assembly, hanging installation, axle installation, wheel installation, electrical installation, trailer tape-out and the like. A frame supporting part, a hanging supporting part, an axle supporting part and a wheel supporting part move in the front-back direction of a horizontal linear guide rail part through supporting rollers or are positioned on the horizontal linear guide rail part through roller positioning mechanism, the parts are not interfered in the assembling-installing process, and rapid assembly is promoted. Accurate assembly and installation distance control can be achieved. Accurate, positioned and rapid hoisting can be achieved. By adopting the usage method of the trailer assembling system, overall and rapid positioning and assembly of a trailer can be achieved, the assembly efficiency is high, and the potential safety hazard of hanging swing installation can be avoided.

The invention discloses a trailer assembly system which comprises horizontal linear guide rail parts (1), vehicle frame supporting parts (2), suspension supporting parts (3), axle supporting parts (4), wheel supporting parts (5) and an electronic control device. The horizontal linear guide rail parts at least comprise vehicle frame mounting guide rails (11), axle mounting guide rails (12) and wheel mounting guide rails (13) which are arranged in a left-right symmetry mode; the bottoms of the vehicle frame supporting parts, the bottoms of the suspension supporting parts, the bottoms of the axle supporting parts and the bottoms of the wheel supporting parts comprise supporting rollers and roller positioning mechanisms correspondingly, and the supporting rollers are arranged to roll in the front-rear direction; and the vehicle frame supporting parts, the suspension supporting parts, the axle supporting parts and the wheel supporting parts are provided with up-down telescopic mechanisms arranged in the up-down direction and workpiece supporting surfaces located at the telescopic ends of the up-down telescopic mechanisms correspondingly. According to the trailer assembly system, overall quick positioning and assembling of a trailer can be achieved, the assembling efficiency is high, and the safety hidden trouble of hoisting and swinging mounting can be avoided.

The invention relates to an electrostatic spinning spray nozzle capable of achieving quick multi-needle-tip positioning and relates to electrostatic spinning. The spray nozzle comprises an upper coverplate, a needle tip mounting plate, an electric conduction plate, a needle tip array and an air cover; the upper cover plate is provided with a liquid inlet and connected with a liquid supply devicethrough a hose; the needle tip mounting plate is of a step structure, the step height difference is identical to the height difference of needle tips at the corresponding positions, and the needle tipmounting plate is provided with a needle tip positioning hole; the electric conduction plate is connected with a positive electrode of a high-voltage supply source and is of a separated structure; the needle tip array is provided with the needle tips distributed in an arc array, the needle tip at the middle position of the needle tip array is located at the lowest point, and the needle tips of the two sides of the needle tip array are symmetrically distributed; the air cover is provided with two air inlets and connected with an air supply device through an air guide pipe, and a pressure adjustment valve is used for controlling flow of air and magnitude of pressure intensity. Sheath air constraint is introduced, spinning jet injection is accelerated, the fiber spraying efficiency is improved, the jet flow is thinned, the diameter of a nano fiber is reduced, and the film formation uniformity and quality of an electrostatic spinning fiber are improved.

The invention discloses a construction method and an installation structure for an antique building roof ridge scorpion glazed decorative component. The method includes: dividing the scorpion glazed decorative component into several multi-layered and multi-column pieces of scorpion glazed assembly components, and sequentially placing them on a roof ridge beam. Set up steel plate embedded parts and risers; install the beast glazed assembly components layer by layer through the riser and align the upper and lower wedges and bond them through the glue layer. Connected by the bolt assembly and the rubber gasket on it, on the sub-top layer of the glass beast glass assembly assembly is inserted into the fire hole through the casing through the riser to the ridge beam and poured concrete to form a support column; Insert a rubber wedge into the gap between the fire hole and the casing; set a non-slip stopper at the wedge position between the sub-top layer and the top layer of the beast glaze assembly. The kiss beast glazed assembly assembly of the invention is light in weight, convenient for firing, not easy to break, high in installation precision, safe in construction, and low in construction difficulty.

The invention discloses a rapid positioning and assembling process of an electric device, belonging to the field of hair trimmer assembly technology. A rapid positioning and assembling process of an electric device is fixedly connected to the hair trimmer by a buffer seat whose upper end is fixedly connected with a rolling arc surface wiper. In the middle of the upper end of the head, by separating the hair trimmer head and the hair trimmer holding part, the two can be separated and replaced separately, and quick positioning and assembly can be realized through the setting of the detection element. The roller-type curved surface wiper can avoid manual application of shaving liquid, without pre-cleaning hands, making the application of shaving liquid more convenient, and combined with the high-speed rotation of the hair trimmer, the shaving liquid can be quickly whipped into a more delicate texture. Foam, smear more evenly; in addition, the setting of the rolling arc surface wiper can massage the skin while shaving, and the user is more comfortable to use.
