4results about How to "The jacking process is stable" patented technology

The utility model provides a dispensing machine with a side edge jacked up, and relates to the technical field of dispensing devices. Comprising a rack, a three-axis movement mechanism arranged on the rack and a dispensing device arranged on the three-axis movement mechanism, and further comprises a jacking device arranged in the movement range of the three-axis movement mechanism, and the jacking device comprises a left jacking device and a right jacking device; an adjustable accommodating space is formed between the left jacking device and the right jacking device, so that a cart can be pushed in; the left jacking device and the right jacking device are suitable for acting on the two sides of the cart so that the cart can be synchronously jacked up from the two sides. The glue dispensing device is suitable for moving to the position above the cart to conduct glue dispensing on materials on the cart after the cart is jacked up and fixed. According to the scheme, the dispensing stability is improved.

The utility model belongs to the technical field of alignment devices, particularly relates to an alignment device for dismounting and mounting a bottom part of a bullet train, and provides the following scheme aiming at the problems that the existing alignment device is inconvenient to move, cannot jack up equipment automatically and lacks a fixing mechanism: the alignment device comprises a base, and two side plates are fixedly arranged on the base; an adjusting mechanism is arranged on the base and comprises a first motor, the first motor is fixedly connected with the base, a first screw rod is fixedly mounted on an output shaft of the first motor, a transverse moving plate is in threaded connection with the first screw rod, and a second motor is fixedly mounted on the transverse moving plate; a second screw rod is fixedly installed on an output shaft of the second motor, a longitudinal moving plate is in threaded connection with the second screw rod, and an inner groove is formed in the longitudinal moving plate. The device is convenient to move, accurate in alignment, high in alignment efficiency, capable of stably jacking equipment and convenient to install.

The invention discloses a heavy anti-collision early warning vehicle which comprises an elastic energy absorption anti-collision panel, a compartment type energy absorption box, a friction energy dissipation bottom plate, a mode conversion driving assembly and an early warning mechanism. The elastic energy absorption anti-collision panel is assembled at the front end of the compartment type energy absorption box, and the compartment type energy absorption box comprises liquid compartments and cavity compartments which are arranged in a staggered mode. The friction energy dissipation bottom plate is fixed to the bottom of the compartment type energy absorption box. The mode conversion driving assembly is assembled in a fixing cavity formed in the bottom of the compartment type energy absorption box and can be used for supporting in the anti-collision working state and lifting the compartment type energy absorption box to be hauled in the hauled state. The early warning mechanism is assembled at the top of the compartment type energy absorption box; through the combined design of the elastic energy absorption anti-collision panel, the compartment type energy absorption box and the friction energy dissipation bottom plate, multi-stage collision buffering is achieved, and vehicle intrusions of different speeds and weights can be coped with; the early warning mechanism is arranged, so that an early warning signal can be sent out in time to remind a driver to pay attention, and the accident risk is further reduced.

The utility model relates to the technical field of ring rolling machine, especially a double station ring rolling machine for rolling and expanding metal ring body, which comprises a rack, a sliding seat, a pushing oil cylinder, a rolling mechanism, a rotating motor for driving the rolling mechanism to rotate, a support roller body rotatably arranged on the rack below the rolling mechanism, the support roller body is used for supporting the ring body and realizing rolling and expansion in cooperation with the rolling mechanism, the rack is in an inclined state with an inclination angle of 5-30 degrees to realize independent support of the metal ring body by the support roller body, the support roller body comprises a first roller part close to the rack and a second roller part outside the first roller part, the diameter of the second roller part is smaller than that of the first roller part, and the rolling mechanism comprises a first rolling part matched with the first roller part and a second rolling part matched with the second roller part. The utility model solves the technical problem that the existing ring rolling machine cannot flexibly adapt to the rolling requirements of different parts of the metal ring body.
