Description

Precast concrete stair transfer device

Technical Field

The utility model relates to construction machinery for construction sites, in particular to a concrete prefabricated staircase transfer device.

Background

At present, along with the national vigorous promotion of building industrialization, industrialization and assembly type standardization, a large number of prefabricated parts are bred in factories, wherein the manufacturing work of stairs is transferred to the factory for production, and the quality of a plurality of prefabricated concrete parts is also different due to the difference of equipment level and management level of the building prefabricated part factories. Especially in some precast concrete member factories with large production capacity and large supply quantity, the problems of insufficient maintenance time of precast members, insufficient storage area, serious ultrahigh stacking height of members and the like generally exist, the product protection in the transportation process is insufficient, and the like, so that the problems can cause serious member quality and safety problems, influence the property safety of enterprises, and even threaten the safety of main structures of buildings.

The traditional method is inconvenient to operate, the form removal strength of the prefabricated staircase is only 70% of the design strength, and a large number of staircases need to be tiled on a storage yard to occupy a large amount of places when the component strength is insufficient. The strength of the member is satisfied, the time is 7-15 days in summer, the time is different 15-30 days in winter, the strength is not more than 3 layers according to the standard requirement after meeting the requirement, the pressure of a storage yard is not relieved, a plurality of factories limited by the field are stacked above 10 layers, the pressure of the bottom member is seriously more than the design requirement, the member can generate cracks and even break, and the member with the penetrating crack depth more than 3mm is discarded. Therefore, the traditional mode occupies a large amount of storage yards, causes the increase of land acquisition area, and increases the risks of component fracture, collision and the like during transportation when the components are laid down.

The utility model discloses a chinese utility model patent that publication number is CN 211548839U discloses a prefabricated concrete stair transfer equipment for assembly type construction, comprising a base plate, the front end at bottom plate top and rear end have all welded the sliding rail, and the sliding tray has all been seted up to two relative one sides of sliding rail, and sliding connection has the movable block between two sliding rails, the inner chamber sliding connection of sliding tray has spacing slide. According to the prefabricated concrete stair transfer device for the assembly type building construction, the lifting device is started to lift the prefabricated concrete stair under the action of the baffle and the shovel plate, the lifting device is pushed to move leftwards, so that the whole prefabricated concrete stair is placed on the transfer device, the moving block is limited and fixed through the unlocking mechanism, and the prefabricated concrete stair is not moved, so that the stability during transfer is improved, a user can conveniently move the prefabricated concrete stair to a proper position, and the construction efficiency is improved.

However, in the transfer process of the device, only one precast concrete stair can be transferred at a time, and the transfer efficiency is low; there is not fixing device to precast concrete stair, drops easily, damages the stair.

Detailed Description

The present invention will be further described with reference to the following examples.

As shown in fig. 1: the utility model is provided with a bottom frame 1, a fork-bearing type interface 2, a fastening upright post 3, a fixed upright post 7 and a link rod 8, wherein the bottom frame 1 is manufactured by processing a national standard square tube, and the square tube is hollow inside, so that a fork shovel of a forklift can directly go deep into the square tube for forking.

As shown in fig. 2, the welding has steel lug 9 on underframe 1, and four lugs 9 are full-welded on the side of underframe, provide hoist and mount convenience for the removal of rack to the support body both sides have welded the lug and also can have adopted the crane handling, transport and transportation convenient and fast.

As shown in fig. 3 and 4, at least one pair of fixed type upright posts 7 and 2 pairs of fork-type interfaces 2 are arranged on the bottom frame 1, and fastening upright posts 3 are vertically inserted into the socket-type interfaces 2, so that the operation is convenient. Form between fastening stand 3 and the fixed standing pillar 7 and hold the accommodation space that precast concrete stair laid on one's side, after stair adopted the transportation stair of formula of standing on one's side, the stair flat board had no pressure and has reduced the stair crack, and the land pressure has been alleviated to the less area occupied in the stock dump of standing on one's side.

As shown in fig. 1 and 5, the middle section of the fastening upright 3 is provided with an adjustable screw 4, a sleeve 5 and a rotary clamp 6 for jacking the precast concrete stair. The rotary clamping device 6 is angle steel welded and fixed at the top end of the adjustable screw rod 4, the shape and the structure of the rotary clamping device are convenient to match with a precast concrete stair, and collision in the transportation process can be reduced after the stair is fastened by the adjusting support.

The adjustable screw 4, the sleeve 5 and the rotating gripper 6 constitute a gripping system. The adjustable screw 4 passes through the sleeve 5, and the rotary clamping device 6 is arranged at the end of the adjustable screw 4 and can rotate 360 degrees. When needing to press from both sides tightly, make rotatory clamping device 6 and stair contact through adjusting adjustable screw 4, press from both sides tightly and can fix the stair, then in the fork shovel that adopts fork truck gos deep into frame square tube to the end, the frame is transported firmly steady.

Because the precast concrete stair is stored in a side standing mode, the occupied area is small, and the site utilization rate is high.
