Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a concrete mixer truck lifting device. Background Technology

[0002] In existing technologies, the concrete pumping process is used for the construction of the superstructure concrete of bridges where the bridge deck is not yet connected. This process has the following disadvantages: the pump pipeline is long, requiring multiple turns and bends, which makes the layout difficult, time-consuming, and material-costly, and carries a high risk of pipe blockage, resulting in low construction efficiency; for long-distance concrete construction on the bridge deck, the pumping system requires extremely high outlet pressure, placing stringent demands on the pump performance; the pumping construction time is long, the pumping resistance is high, and the workability and fluidity of the concrete are highly demanding. In case of emergencies, the concrete may solidify if it is not stirred for a long time; the continuous pulse vibration during the pumping process can be transmitted through the pump pipeline and supports to the freshly poured and unset concrete, which may cause the internal aggregates to sink and the slurry to float, affecting uniformity and even causing micro-cracks at the joints with the already poured sections.

[0003] To address the aforementioned issues, concrete mixer trucks can be lifted onto the bridge deck for operation, making the lifting equipment crucial. Currently, there are no dedicated lifting devices; direct lifting using wire ropes results in relatively poor stability and poses safety hazards. For example, patent CN220264918U discloses an adjustable mixer truck lifting device and lifting system, including a T-beam. The T-beam comprises a crossbeam and a longitudinal beam, with an inclined beam connecting the crossbeam and the longitudinal beam. A first lifting structure is provided on the inclined beam, with multiple first lifting holes sequentially arranged along the length of the inclined beam. One end of the longitudinal beam is fixed to the crossbeam, and the other end is provided with a second lifting structure, with multiple second lifting holes sequentially arranged along the length of the longitudinal beam. This system can only be used for lifting the mixer truck's tank body and is not suitable for lifting the entire concrete mixer truck. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a concrete mixer truck lifting device that can stably and safely lift concrete mixer trucks.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: The concrete mixer truck lifting device includes a frame beam wire rope, a frame beam, a platform wire rope, a load-bearing platform, and a wheel chock placed on the load-bearing platform. The load-bearing platform carries the concrete mixer truck and is connected to the frame beam via the platform wire rope. The frame beam is connected to the hook via the frame beam wire rope. The wheel chock is used to fix the position of the concrete mixer truck.

[0006] Further or preferred: The frame beam includes a main beam, a connecting beam, a top lifting lug, and a bottom lifting lug; the main beam is provided with two cross-connecting beams, which are fixed together by the connecting beam; and the top and bottom surfaces of the two main beams are provided with four top lifting lugs and four bottom lifting lugs, respectively.

[0007] The load-bearing platform includes longitudinal beams, transverse beams, distribution beams, panels, wedge-shaped ramps, and platform lifting lugs; the longitudinal beams, transverse beams, and distribution beams are welded to form a platform frame, a wedge-shaped ramp is set at one horizontal end of the platform frame, and platform lifting lugs are arranged on the top surface of each longitudinal beam.

[0008] Two wedge-shaped ramps are symmetrically arranged, with a triangular longitudinal cross-section and the top surface flush with the load-bearing platform.

[0009] The platform lifting lugs are symmetrically arranged on the top surface of the longitudinal beam in four sets, with 3-5 lugs in each set at equal intervals.

[0010] The platform lifting lugs in each corresponding sequence have the same longitudinal and transverse spacing as the bottom lifting lugs set at the bottom of the frame beam.

[0011] The top surface of the load-bearing platform is equipped with eight wheel wedges, and the bottom of the wheel wedges is provided with an anti-slip layer. The position of the wheel wedges can be adjusted as needed.

[0012] Compared with the prior art, this utility model has the following advantages: This concrete mixer truck lifting device features a rationally designed structure. The load-bearing platform facilitates the self-driving entry and exit of the concrete mixer truck. Multiple lifting lugs on the top of the platform can be adjusted according to the truck's center of gravity after entry, ensuring even stress distribution and stable lifting. A frame beam ensures the vertical arrangement of the platform's steel cables, preventing collisions with the concrete mixer truck. The frame beam, through its intersecting main beams and connecting beams, forms a stable framework with clearly defined stress distribution. This lifting device enables the rapid and safe lifting of concrete mixer trucks to the construction bridge deck. Attached Figure Description

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0021] like Figures 1 to 6 As shown, a concrete mixer truck lifting device includes a frame beam wire rope 1, a frame beam 2, a platform wire rope 3, a load-bearing platform 4, and a wheel chock 5 placed on the load-bearing platform 4; the frame beam wire rope 1 connects the hook and the frame beam 2, the platform wire rope 3 connects the frame beam 2 and the load-bearing platform 4, the load-bearing platform directly supports the concrete mixer truck, and the wheel chock 5 is used to fix the position of the concrete mixer truck.

[0022] The frame beam 2 includes a main beam 201, a connecting beam 202, a beam top lug 203, and a beam bottom lug 204. The main beam 201 is provided with two cross-connections. The cross-arranged main beams 201 are fixed by the connecting beam 202. The top and bottom surfaces of the two main beams 201 are provided with four beam top lugs 203 and four beam bottom lugs 204, respectively.

[0023] The load-bearing platform 4 includes longitudinal beams 401, transverse beams 403, distribution beams 404, panels 406, wedge-shaped ramps 402, and platform lifting lugs 405. The load-bearing platform and all components are made of steel to meet the strength and rigidity requirements.

[0024] Furthermore, the load-bearing platform 4 is composed of longitudinal beams 401, transverse beams 403, and distribution beams 404 welded together to form a platform frame, which is structurally stable.

[0025] A wedge-shaped ramp 402 is set at one end of the load-bearing platform. The cross-section of the wedge-shaped ramp 402 is triangular, with the top surface flush with the load-bearing platform 4 and the bottom surface connected to the ground. The width of the wedge-shaped ramp covers the width of the concrete mixer truck tires. After the load-bearing platform is lowered to the ground or beam surface, the concrete mixer truck can automatically get on and off the load-bearing platform at the wedge-shaped ramp position, ensuring stable and reliable operation.

[0026] Four sets of platform lifting lugs 405 are symmetrically arranged on the top surface of the longitudinal beam 401, with four lugs in each set at equal intervals. The four platform lifting lugs 405 can be selected according to the center of gravity position after the load is applied, ensuring stable lifting.

[0027] The concrete mixer truck enters the load-bearing platform 4 at the wedge ramp 402. Its position is fixed by eight wheel wedges 5 set on the top surface of the load-bearing platform 4. According to the overall center of gravity of the load-bearing platform 4 and the concrete mixer truck, four corresponding platform lifting lugs 405 are selected and connected to the bottom of the platform wire rope 3. The top of the platform wire rope 3 is connected to the frame beam 2. The frame beam 2 is connected to the hook of the lifting equipment through the frame beam wire rope 1. The lifting equipment lifts the concrete mixer truck full of concrete to the bridge deck and then lifts the concrete mixer truck that has been unloaded to the ground.

[0028] This patented design features a load-bearing platform that facilitates the autonomous entry and exit of concrete mixer trucks. Multiple lifting lugs on the top of the platform can be adjusted according to the center of gravity of the truck, ensuring even stress distribution and stable lifting. A frame beam ensures the vertical arrangement of the platform's steel cables, preventing collisions with the concrete mixer truck. The frame beam, with its intersecting main beams and connecting beams, forms a stable framework with clearly defined stress distribution. This invention enables concrete mixer trucks to quickly access construction sites such as bridges without traffic access. Compared to traditional concrete pumping processes, this method is convenient and fast, improving construction efficiency and solving the quality control challenges of long-duration, long-distance concrete pumping.
