The invention provides a counterbalance forklift frame which comprises a frame body, the frame body comprises a left side structure assembly and a right side structure assembly, and the front end and the rear end of the left side structure assembly and the front end and the rear end of the right side structure assembly form a stable frame body structure through a rear tail frame and a plurality of transverse connecting plates in a surrounding mode; a first supporting assembly used for fixing an engine is arranged on the upper rear portion of the inner side of the frame body, and a second supporting assembly used for fixing a power battery is arranged on the lower middle portion of the inner side of the frame body. The space capable of containing the engine and arranging the power battery is formed in the frame body, the space utilization rate of the forklift frame is increased, and the forklift can carry the internal combustion engine and the power battery at the same time.

The application relates to the technical field of bridge erection, in particular to a construction method of a bridge erecting machine and a single-arm bridge erecting machine. The construction method of the bridge erecting machine is as follows: when the construction line is a small curve section, the front supporting leg assembly and the middle supporting leg assembly are folded, the first horizontal moving mechanism is used to drive the front supporting leg assembly to move horizontally to the inside of the curve, the second horizontal moving mechanism is used to drive the middle supporting leg assembly to move horizontally to the outside of the curve, the first horizontal moving mechanism is used to drive the machine arm at the front supporting leg assembly to move horizontally to the inside of the curve when the front supporting leg assembly and the middle supporting leg assembly are supported, the second horizontal moving mechanism is used to drive the machine arm at the middle supporting leg assembly to move horizontally to the outside of the curve, and the centers of the two ends of the machine arm can be adjusted to coincide with the centers of the first bridge pier and the second bridge pier. Therefore, when the small curve girder erection is carried out, the bridge erecting machine does not need to be modified, the process of the bridge erecting machine passing through the small curve is simplified, the construction efficiency of the bridge erecting machine is improved, and the bridge erection time of the small curve section is reduced.

The utility model provides a plurality of horizontally placed wafers, which relates to the technical field of wafers, and comprises a supporting sheet, a plurality of mutually overlapped wafer protection groups are placed at the top end of the supporting sheet, buckling films are placed at the top ends of the wafer protection groups, and buckling top covers are arranged at the top ends of the buckling films. And connecting buckle plates are fixedly mounted at the two ends of the buckling top cover.

The invention belongs to the field of control algorithms of target turning angle control systems, and particularly relates to a target turning angle control method and system based on steer-by-wire. The target turning angle control method based on the steer-by-wire comprises the steps that the current vehicle speed value and the gear target turning angle of a target turning angle control system during steering are obtained; calculating a first target rotation angle compensation angle and a second target rotation angle compensation angle according to the current vehicle speed value and the gear target rotation angle; determining one of the first target corner compensation angle and the second target corner compensation angle as a current compensation angle according to the current vehicle speed value; and compensating the target rotation angle of the gear by using the current compensation angle. The target rotating angle of the gear is adjusted through the selected compensation angle, and more accurate and stable steering control is achieved. At a low speed and a small steering wheel rotation angle, the compensation can reduce unnecessary transverse movement, and the problem that the transverse movement amount of a target rotation angle control system is too large due to a large steering angle caused by the low speed and the small steering wheel rotation angle is solved.
