Description

Technical Field

[0001] This invention relates to the field of building construction, and in particular to a component handling device and method that can be pried up and lifted. Background Technology

[0002] After precast components arrive at the construction site, it is easy to encounter problems with incorrect hoisting positions. In such cases, it is often necessary to move the precast components to the correct location. In the traditional approach, construction workers use crowbars to pry up the precast components and then use a winch to lift and transport them to a transport vehicle. This method of using crowbars to pry up the precast components often damages the concrete protective layer of the precast components. At the same time, due to the large weight of the precast components, using a winch to lift them can easily cause safety hazards. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a component handling device and method that can be pried up and lifted, which is highly safe and will not damage the prefabricated components.

[0004] To achieve the above objectives, the present invention adopts a component handling device that can be pried up and lifted, comprising: a trolley body, a pry plate fixed to the front end of the trolley body and extending forward beyond the trolley body, two lifting components disposed on both sides of the trolley body, and a propulsion component that can simultaneously drive the two lifting components to move back and forth between the trolley body and the front end of the pry plate under the action of external force. The lifting component includes a lifting frame connected to the propulsion component and a lifting plate vertically movably connected to the lifting frame. The lifting plates of the two lifting components extend inward relative to each other to the pry plate.

[0005] A further improvement of the component handling device of the present invention is that the trolley body includes a horizontal frame, a caster wheel connected to the bottom of the rear crossbar of the horizontal frame, and the pry plate is connected to the front crossbar of the horizontal frame.

[0006] A further improvement of the component handling device of the present invention, which can be pried up and lifted, is that the propulsion assembly includes:

[0007] A pedal, which is rotatably connected about the rear crossbar of the horizontal frame;

[0008] A connecting rod, the first end of which is rotatably connected to the bottom of the pedal, and the rotation direction of the connecting rod is the same as the rotation direction of the pedal;

[0009] The push pulley, which is rotatably connected to the second end of the connecting rod, is pushed against the bottom of the pry bar. During the process of pressing down the pedal, the connecting rod drives the push pulley to move from the rear end of the pry bar to the front end of the pry bar.

[0010] A horizontal shaft passes through the axle of the propulsion pulley and is connected at both ends to the two lifting frames.

[0011] A further improvement of the component handling device of the present invention is that the second end of the connecting rod is also connected to a stop bar for protecting the push pulley, the stop bar being located above the push pulley and abutting against the bottom of the pry plate.

[0012] A further improvement of the component handling device of the present invention is that the lifting frame includes a base plate and a jack connected to the top surface of the base plate. The lifting plate is a Z-shaped plate. The lifting plate includes a first flange plate for connecting to the top of the jack and a second flange plate extending inward to the pry plate for placing the component to be moved. A wheel set is connected to the bottom of the base plate, and the horizontal axle is coaxially connected to the wheel axle of the wheel set.

[0013] A further improvement of the component handling device of the present invention is that the jack is a hand-cranked jack, and an inverted U-shaped downward pressure rod is connected between the two jacks. The inverted U-shaped downward pressure rod includes a web for the construction worker to hold, and two flange rods for connecting to the hand cranks of the two jacks respectively.

[0014] A further improvement of the component handling device of the present invention is that the base plate has a through hole for the web of the lifting plate to pass through, and a vertical rod is connected between the base plate and the wheel assembly, so that a lifting space for the lifting plate to be raised and lowered is formed below the base plate.

[0015] A further improvement of the component handling device of the present invention is that two guide plates are vertically connected to the top surface of the base plate, the two guide plates are respectively located on both sides of the through hole, guide rods are respectively connected to both sides of the web of the lifting plate, and guide grooves are vertically opened on the guide plates for the guide rods to pass through.

[0016] A method for handling a component that can be pried up and lifted, comprising the steps of:

[0017] Step 1: Provide the aforementioned conveying device;

[0018] Step 2: Drive the two trolley bodies and insert the pry plates at the front ends of the two trolley bodies into the opposite sides of the component to be transported;

[0019] Step 3: Drive the propulsion components on the two trolley bodies respectively, and drive the corresponding lifting components to move towards the front end of the skid. As the lifting components move, the skid is lifted until the corresponding lifting plate moves to the bottom of the prefabricated component to be transported.

[0020] Step 4: Synchronously drive the lifting frames on the two transport devices to lift the component to be transported until it is off the ground.

[0021] A further improvement of the pry-up and lifting component handling method of the present invention is that:

[0022] The trolley body includes a horizontal frame, universal wheels connected to the bottom of the rear crossbar of the horizontal frame, and the pry plate is connected to the front crossbar of the horizontal frame.

[0023] The propulsion assembly includes: a pedal rotatably connected to the rear crossbar of the horizontal frame; a connecting rod, the first end of which is rotatably connected to the bottom of the pedal, the rotation direction of the connecting rod being the same as that of the pedal; a propulsion pulley abutting against the bottom of the skid plate, the propulsion pulley being rotatably connected to the second end of the connecting rod; and a horizontal shaft passing through the axle of the propulsion pulley and having its two ends respectively connected to the two lifting frames.

[0024] When performing step 3, the pedal is depressed, causing the two lifting components to move to the front end of the pry bar, while simultaneously prying up the component to be moved, thereby causing the two lifting plates to be inserted into the gap where the component to be moved is pryed up.

[0025] Compared with the prior art, the advantages of the present invention are:

[0026] 1. The construction worker steps on the pedal to push the lifting assembly to the bottom of the component to be moved, and then the construction worker presses down the inverted U-shaped pressure rod to activate the lifting assembly to lift the component to be moved. The overall structure is lightweight and effortless, which improves construction efficiency.

[0027] 2. By installing a stop bar above the push pulley, damage to the push pulley due to the weight of the component to be transported during the push process can be avoided. Attached Figure Description
