This utility model relates to the field of climbing formwork support frame technology, and discloses a climbing formwork device for building construction, including a base plate, a support frame installed on one side of the base plate, and a fence with a U-shaped structure fixedly installed on the outer edge of the top of the base plate; a drive mounting groove is opened in the middle of the upper surface of the support frame, and a slot is opened on the lower side of the support frame near the drive mounting groove. This utility model, by setting up locking blocks, protrusions, and bolts, allows for the removal of the base plate mechanism by disassembling the bolts when reloading the construction work. Due to the universal wheels, the disassembled base plate mechanism can be pushed away, and then the base plate mechanism fully loaded with construction work can be moved to one side of the support frame, where the locking blocks and slots are engaged, and the bolt assembly can be reinstalled. This allows the base plate mechanism to be put into use immediately after replacement, and the disassembled base plate mechanism can be used by ground personnel to reload construction work. This alternating loading and unloading method reduces the time spent on loading and indirectly improves construction efficiency.

The utility model discloses a marine engine transport ship, which relates to the technical field of shipbuilding industry and comprises a ship body and a hatch cover, the ship body comprises a head section, a cargo compartment section and a tail section which are integrally connected in sequence, and the cargo compartment section is provided with an engine placing cavity with a top opening. The engine containing cavity is higher than a marine engine needing to be transported, and the hatch cover is used for being in rigid sealing connection with the top of the cargo hold section so as to open or seal a top opening of the engine containing cavity. The rear enclosure bulkhead comprises a fixed enclosure bulkhead and a movable enclosure bulkhead, the bottom of the movable enclosure bulkhead is hinged to the top of the fixed enclosure bulkhead, and the movable enclosure bulkhead can be overturned to the horizontal position in the direction away from the engine containing cavity and can be overturned to make contact with the fixed enclosure bulkhead, the left enclosure bulkhead, the right enclosure bulkhead and the hatch cover and be in sealed connection with the fixed enclosure bulkhead, the left enclosure bulkhead and the right enclosure bulkhead; weather tight closing of the warehouse can be achieved, the engine transportation requirement is met, loading and unloading are convenient, and the hoisting requirement of a shipyard is effectively met.

The utility model relates to a standing device. The standing device comprises a standing assembly which comprises a standing tank, the standing tank is horizontally arranged in the length direction, an opening is formed in one side of the standing tank, and the opening is communicated with an inner cavity of the standing tank; and the side door opening assembly comprises a tank door for closing or opening the opening. Compared with the prior art, the standing device has the advantages that on one hand, opening and closing of the tank door can be realized without lifting action, and on the other hand, the hoisting height of a clamp loaded with a battery is greatly reduced, so that the height of hoisting equipment is greatly reduced, and the space (especially the height space) required to be occupied by the equipment is greatly reduced; and the cost for transforming a plant is saved, and meanwhile, the energy consumption of equipment is also reduced.

This invention discloses a method for rapid replacement of filling mortar with low rail lifting, comprising: lifting the rail and track slab at a low height; installing a series of cutting devices on the track slab, with the main body of the devices located between the track slab and the base; adjusting the height of the cutting mechanism through a positioning mechanism to control the mortar cutting thickness; operating the cutting trolley to cut the filling mortar laterally along the track; after one lateral cutting pass, moving the series of cutting devices longitudinally along the track; repeating the lateral cutting, longitudinal movement, and vertical height adjustment steps until the mortar under the entire track slab is cut; dismantling the series of cutting devices; cleaning the base surface; lowering the track slab for fine adjustment; injecting new filling mortar; and restoring the rail. This invention reduces the lifting height of the rail and track, reduces workload, alleviates the labor intensity of personnel, and improves construction efficiency; it is suitable for operation during maintenance windows on operating railway lines.

The auxiliary feeding mechanism comprises a machine base, a sliding plate, a telescopic mechanism and a discharging base, the sliding plate is longitudinally installed on one side of the machine base in a sliding mode through the sliding mechanism, the telescopic mechanism is further installed on the machine base, and the telescopic end of the telescopic mechanism is connected with the sliding plate so as to drive the sliding plate to move up and down. The discharging base is installed on the sliding plate through a pivot hinge structure, so that the discharging base can swing left and right, and a longitudinal through limiting hole is formed in the discharging base. According to the utility model, a workpiece can be placed on the discharging seat at a low position on the outer side of the gear shaping machine, then the workpiece is moved to a position above the hydraulic clamp through the ascending and rotating of the discharging seat, and then the discharging seat descends to load the workpiece into the hydraulic clamp, so that the workpiece is prevented from being hoisted to a high position through hoisting equipment, and the working efficiency is improved. And potential safety hazards caused by manual traction and pushing of the workpiece into the hydraulic clamp are avoided.

The utility model discloses a hoisting balance beam for double-crane hoisting, which belongs to the technical field of equipment hoisting and comprises a cross beam body, and a middle-section steel wire rope hanging point is fixed at the middle position of the top of the cross beam body; a left steel wire rope hanging point and a right steel wire rope hanging point are respectively fixed on two sides of the middle steel wire rope hanging point on the top of the beam body; a left-side travelling crane lifting point and a right-side travelling crane lifting point are respectively fixed at the two end parts of the top of the cross beam body; and the left steel wire rope hanging point and the right steel wire rope hanging point as well as the left travelling crane hanging point and the right travelling crane hanging point are symmetrically arranged relative to the midpoint of the cross beam body. The hoisting balance beam disclosed by the utility model can reasonably distribute and balance the load of each hoisting point, so that the horizontal pressure borne by equipment during hoisting is reduced, the stability of the equipment during hoisting is ensured, the equipment is prevented from being damaged, and the equipment is effectively protected. Meanwhile, the height of the sling can be shortened, the lifting height of the movable pulley is reduced, and therefore the safety of lifting construction is improved.
