[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] like Figure 1-3As shown, a material handling vehicle for construction sites includes a frame 1 and a rotatable carriage 4, wherein a handle 2 is fixedly connected to the rear side of the frame 1 for easy pushing and moving; wheels 3 are installed at the bottom of the frame 1 for saving time and effort when pushing; the bottom front end of the rotatable carriage 4 is hinged to the front top surface of the frame 1, and the bottom rear end of the rotatable carriage 4 is connected to the rear top surface of the frame 1 through a jacking drive member 8.

[0028] Specifically, the rotatable carriage 4 includes a left side plate, a right side plate, a back plate, a front side door 6 and a bottom plate. The left side plate, the right side plate and the back plate are connected to each other and the bottom is fixedly connected to the bottom plate. The top ends of the left side plate and the right side plate are connected to a crossbeam 5. The top end of the front side door 6 is hinged on the crossbeam 5. The bottom of the front side door 6 is provided with a locking assembly. The left side plate and the right side plate are provided with a telescopic plate 7. Specifically, through the lifting action of the lifting drive 8, it is convenient to lift the rear side of the rotatable carriage 4 to tilt it, which is convenient for dumping the materials after they are transported to the right place, and the operation is time-saving and labor-saving.

[0029] like Figure 2 As shown, a second lower articulated seat 102 and a first lower articulated seat 101 are respectively installed on the front and rear sides of the top surface of the frame 1, and an air avoidance groove is arranged in the middle of the rear side of the rotatable carriage 4, in which a first upper articulated seat 402 is installed, and the first upper articulated seat 402 corresponds to the first lower articulated seat 101 and is rotatably connected to the two ends of the jacking drive member 8 through an articulation shaft; a second upper articulated seat 403 is installed in two grooves on the front side of the bottom plate of the rotatable carriage 4, and the second upper articulated seat 403 is rotatably connected to the second lower articulated seat 102 through an articulation shaft.

[0030] Specifically, the jacking drive component 8 can adopt a linear motor or a pneumatic cylinder or an oil cylinder, which can be connected to the power supply, air pump or hydraulic station of the construction site when in use. During the jacking operation, the telescopic rod is extended to complete the tilting unloading of the rotatable carriage 4. After the unloading is completed, the telescopic rod is retracted and the rotatable carriage returns to a horizontal state.

[0031] Specifically, the left and right plates are provided with telescopic grooves, and the telescopic plate 7 can be installed in the telescopic grooves so as to move up and down. The sides of the left and right plates near the opening of the telescopic grooves are provided with spring positioning beads 401. A plurality of limiting grooves 701 are provided on one side of the telescopic plate 7, and the limiting grooves 701 cooperate with the spring positioning beads 401. When positioning, the spring positioning beads 401 are embedded in the limiting grooves 701. In order to further facilitate operation, a handle can be provided on the top surface or side surface of the telescopic plate 7. When it is necessary to transport sheet materials, the telescopic plate is pulled out and the plurality of telescopic plates cooperate to form a positioning space, and then the sheet materials or steel bars are overlapped in the positioning space on the top surface. The design of this structure can realize the rapid positioning of sheet materials or steel bars. When transporting, a single vehicle can be used or two vehicles can be used to realize the pushing and transfer of sheet materials or steel bars. When not in use, the telescopic plate is in the telescopic groove.

[0032] like Figure 3 As shown, the top end of the front side door 6 is hinged to the cross beam 5 through a hinge joint 11, a positioning groove is provided on the outer side wall of the cross beam 5, a rotating stop rod 12 is hinged in the positioning groove, the rotating stop rod 12 is parallel to the hinge joint 11 when placed horizontally, and is higher than and perpendicular to the top surface of the cross beam 5 when the rotating stop rod 12 is rotated to a vertical state.

[0033] When the sheet needs to be transported, the rotating lever on the beam is rotated vertically to form a limited space with the vertical lever of the handle in front, and then the sheet is overlapped on the top surface. The design of this structure can realize the rapid positioning of the sheet, and the sheet can be moved by a single vehicle or two vehicles; when not in use, the rotating lever is placed in a horizontal state.

[0034] Specifically, the locking assembly includes a locking plate 601 and a locking member 9. The locking plate 601 is positioned and connected to the bottom front side of the front side door 6. The locking member 9 passes through the through hole on the locking plate 601 and is connected to the locking hole 103 of the frame 1. The locking member is designed as a special-shaped bolt, and a ring-shaped hole is provided on the top. When there are too many materials on the vehicle, the motor vehicle can be hung together with the ring-shaped hole of the locking member to assist in moving. The operator only needs to grasp the direction by the handle. During the material loading and handling process, the locking member 9 is screwed and connected in the locking hole 103 to ensure that the rotatable carriage 4 is connected to form a box with an open top to realize the transportation of bulk materials; when unloading is required, the locking member 9 is first loosened and removed, and then when the rotatable carriage 4 is lifted and tilted, the front side door 6 is naturally opened by gravity, so that the material can be quickly poured out, and the operation is time-saving and labor-saving; after unloading, the locking member 9 is installed back to keep it in a locked state.

[0035] Specifically, a plurality of buffer pads 10 are arranged at the center of the top surface of the frame 1, and the top surface of the buffer pad 10 abuts against the bottom plate of the rotatable carriage 4. The free height of the buffer pad 10 is greater than the gap between the top surface of the frame 1 and the rotatable carriage 4, and provides a buffer force during the reset process after unloading to avoid hard impact, thereby reducing vibration damage.

[0036] The use process of the utility model is as follows, which mainly includes the handling of two types of materials:

[0037] 1) Sand and gravel bulk material handling operation: During the material loading and handling process, the locking member 9 is screwed and connected in the locking hole 103, and the operator pushes or the motor vehicle assists to realize the bulk material transportation operation; after arriving at the designated location, the locking member 9 is first loosened and taken out, and then the jacking drive member 8 is started to jack up and tilt the rotatable carriage 4, and the front side door 6 opens naturally due to gravity, and the material pours out quickly; after the unloading is completed, the locking member 9 is installed back to keep it locked. During this process, the telescopic plate and the rotating stopper are in a non-working state.

[0038] 2) Handling of steel bars or plates: According to the size of the material to be handled, choose whether to pull out the telescopic plate or rotate the rotating lever to a vertical state;

[0039] When transporting steel bars, it is preferred to pull out the telescopic plate. The gap between the two adjacent plates is small, which is convenient for forming a stable positioning and can be placed left or right. When it is necessary to transport wider plates, you can choose to rotate the rotating baffle rod to a vertical state and place it front or back.

[0040] The utility model has a reasonable layout and is suitable for the transportation of sand and gravel bulk materials as well as the transportation of steel bars, plates and the like. It has a wide range of applications and can be used in conjunction with motor vehicles during movement, making loading and unloading operations and movement more convenient and quick.
